SENKEN warning lightbars
Solar flash warning lights are widely used in road intersections, bends, bridges and other dangerous sections with potential safety hazards, to remind drivers or pedestrians to pay attention, which can effectively play a warning role and avoid traffic accidents and accidents. The shell of this product is composed of aluminum alloy profiles, the surface is sprayed with plastic, the appearance is exquisite, and the warning effect is good. The flash lamp adopts sealed combination lamp group, each group consists of 30 ultra bright imported LED chips. The polycarbonate lampshade is impact resistant, aging resistant and has high transparency. Several flash mode controller, light control, overcharge, over discharge protection, fast flash, slow flash, stroboscopic flash, explosion flash (can be designed according to customer requirements) product performance is stable, quality is reliable.
With the development of society, the construction of buildings and roads is gradually increasing, and the frequent use of large mechanical vehicles such as cranes and excavators in the power line protection area, the phenomenon of building and road construction is more and more, which poses a threat to the safe operation of power lines. Most of the external force damage is caused by crane and tower crane concrete pump truck, which can account for more than 60% of overhead line accidents. Especially at night, because the construction personnel can not see the specific location of the high-voltage wire, the line trip accidents often occur, accounting for 70-80% of the external force accidents
1. Materials and methods
Materials: (1) super bright LED; (2) rubber pad 45 * 18 * 12 (3) bracket 51 * 18 * (4) compression spring (5) printed circuit board (6) circuit wiring (7) lithium battery for storage device; (8) single weight: 420g (9) size: φ * 30 φ 69 * 30 pin length 26mm (10) compression spring bolt 5 * 42 (11) control module IC (12) photovoltaic solar panel (13) package: epoxy sealant (14) shell PC
Installation method
(1) Put the high-voltage operation arm under the wire to be installed, and two workers shall take the installation tools and warning lights. The length of the operating rod of the installation tools shall meet the requirements of the effective length of the line voltage level, and keep enough safe distance from the wire.
(2) Place the warning light in the installation tool, and separate the two pressure springs of the warning light with a special driver Use installation tools_ Hang up the upper hook respectively, and slowly lift the lamp to the wire with the operating rod, away from the wire When it is about 200 mm, align with the installation position, touch the wire with force, and connect the tool hook with the warning light spring Disconnect and press the spring on the wire. Staff down. The installation is complete.
Through the LED light to outline the location of high-voltage wire, guide the driver's line of sight, improve the awareness rate of construction personnel to ensure the safety of overhead lines. We randomly surveyed 100 construction workers in 10 construction sites before and after installation, and the cognition rate increased from 25% to 85%.
Effective methods to improve the performance of solar LED flashover warning light
PC bulletproof material is used for the solar panel on the surface. IC control is used as far as possible to reduce the volume of the sub circuit. The suspension bracket is made of stainless iron to ensure durability and no rust. The pressure spring is made of stainless steel wire to ensure the spring pressure. The fixing on the wire is firm and reliable, and the live installation and disassembly are convenient. High quality rubber is used to ensure good elasticity and prolong aging time. The surface is made into colloidal anti-skid treatment to ensure the firmness after installation. To improve the sealing performance of solar LED flashover warning light
If the solar LED flash warning light is not completely sealed, it will naturally seep, and the seeping water will disappear
Cause circuit short circuit, the consequences are disastrous, so a qualified wire solar LED flash warning light sealing performance must also pass. The separation design can improve the sealing performance of solar LED flashover warning light. The LED lampshade and the internal circuit board adopt isolation design, even if the LED lampshade is broken, the inner part of the solar LED flashover warning light of the conductor still can not be penetrated; the strong neutral bonding material is used to ensure that the solar panel, the LED lampshade and the shell of the solar LED flashover warning light of the conductor are closely bonded, and there is no gap in the middle.
Solar LED flash warning light, light control active light. Clear outline of high voltage overhead line conductor
Line outline. Compared with the reflective luminous warning signs, one of the most important characteristics is the high luminous intensity. The luminous brightness can reach 2000 MCD, and the visual distance is far more than 500 meters. It is 6 to 7 times of the ordinary LED light, with 360 degree illumination. Such a high intensity of light can penetrate the rain and fog at night, safely and effectively remind the crane and mechanical drivers to keep a safe distance from the specific direction of the high-voltage wire; Another important feature is the dynamic sense. The light control LED solar flash warning light flashes at a certain frequency at night, and people's vision is more sensitive to changing light, so its dynamic warning function is very strong. Active lighting not only can avoid the interference of rain and fog to the greatest extent, but also can be separated from the dependence on the scene lighting, the visual distance is longer, and it plays a better effect in eliminating the security risks.
Battery life is an important factor to determine the life of solar LED flashover warning lamp Element is the life of battery, so the choice of battery is very important.
The design of electronic circuit board must follow the principle of simple and effective design, do not artificially complicate, because more than one circuit has more than one possibility of failure. Electronic components should also be strictly selected, because any electronic component problems may make the whole system paralyzed.
The welding must be reliable, because the solar LED flashover warning light of the wire bears the vibration impact of the wire every day, and the slight looseness of the solder joint will lead to the looseness and fall off of the wire. Therefore, when choosing the soldering gun and solder, we must choose high-quality products to ensure that the solder joint is firm and reliable and can work in a relatively "bad" environment for a long time.
Environmental adaptability: the use environment of solar LED flash warning light is complex and changeable, and the temperature and humidity may be very different. The temperature is very low in winter in the north, and it is very high in summer in the south, and the temperature difference between day and night in the northwest is particularly large, which will affect whether the solar LED flashover warning light works normally. It can also be used for 25-400 square millimeter wires and voltage levels, Therefore, the design of the solar LED flashover warning lamp should fully consider the environmental adaptability. The environmental adaptability of the solar LED flashover warning lamp is a comprehensive test of its mechanical and electrical properties, involving structural design, circuit design, electronic device performance and other aspects, even including its production process. This also requires that all aspects of the work should be done in place, in order to ensure that the solar LED explosion warning light has better environmental adaptability.
