DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] Refer to Figure 1-6, a power grid equipment maintenance warning device, comprising:

[0031] A protection box 1; a high-temperature automatic heat dissipation device is fixedly arranged inside the protection box 1, and a natural heat dissipation mechanism is fixedly arranged on the bottom side of the protection box 1;

[0032] A placement plate 2, which is fixedly connected to the inner bottom of the protection box 1;

[0033] A warning device 3, which is detachably connected to the top side of the placement plate 2;

[0034] A top cover 4, which is slidably connected to the top side of the protection box 1, and a locking mechanism is fixedly arranged on one side of the top cover 4;

[0035] A controller 5, which is fixedly connected to one side of the protection box 1;

[0036] A wind guide plate 6, which is fixedly connected to the bottom side of the placement plate 2 and abuts against one side of the protection box 1.

[0037] In order to provide a natural heat dissipation function for the warning device 3, the natural heat dissipation mechanism includes: a heat conduction rod 7, the heat conduction rod 7 is connected to the bottom side of the placement plate 2 through screw transmission, a heat dissipation fin 8 is detachably sleeved on the outer side of the heat conduction rod 7, the heat conduction rod 7 is made of graphene plate, and a number of diamond-shaped air holes are arranged on one side of the heat dissipation fin 8;

[0038] When the warning device 3 is in use, heat is generated. The placement plate 2 is heated, and the heat is transmitted to the heat dissipation fin 8 through the heat conduction rod 7. Through the diamond-shaped air holes on the heat dissipation fin 8, heat dissipation operation is carried out by relying on natural wind. The heat conduction rod 7 is made of graphene plate. Graphene has very good heat conduction performance. The thermal conductivity of pure defect-free single-layer graphene is as high as 5300 W / mK, which is the highest carbon material with the highest thermal conductivity so far, higher than that of single-walled carbon nanotubes (3500 W / mK) and multi-walled carbon nanotubes (3000 W / mK). When it is used as a carrier, the thermal conductivity can also reach 600 W / mK. In addition, the ballistic thermal conductivity of graphene can lower the lower limit of the ballistic thermal conductivity of carbon nanotubes per unit circumference and length.

[0039] To avoid the situation where the warning device 3 generates high temperature during use and natural heat dissipation cannot eliminate the high temperature, resulting in high-temperature damage to the warning device 3, a high-temperature automatic heat dissipation device is provided, including: a temperature sensor 9, which is fixedly connected to the inner side of the protection box 1. There are heat dissipation air holes 10 on both sides of the protection box 1. Two baffles 11 are slidably connected to the inner side of the protection box 1. A rack 12 is fixedly provided on one side of the baffle 11. A gear 13 is connected to the rack 12 through tooth transmission on one side. A connecting rod 14 is fixedly provided between the opposite sides of the two gears 13. A micro motor 15 is detachably connected to one side of the protection box 1. The shaft end of the micro motor 15 is connected to one side of the connecting rod 14. Two fans 16 are fixedly provided symmetrically in parallel on the top side of the top cover 4. The temperature sensor 9, the micro motor 15, and the fans 16 are all electrically connected to the controller 5 through wires;

[0040] When the warning device 3 is at high temperature, the temperature sensor 9 detects the high-temperature signal and sends a signal to the controller 5. At the same time, the controller 5 controls the micro motor 15 and the fans 16 to start working respectively. The micro motor 15 drives the connecting rod 14 to rotate, so that the gear 13 drives the rack 12, and the rack 12 drives the baffle 11 to move upward, opening the heat dissipation air holes 10. The fans 16 start to blow air. Cooperating with the air guide plate 6, the air flow blown by the fans passes through the warning device 3, and then the heat flow is blown out through the heat dissipation air holes 10 under the guidance of the air guide plate 6, forming air-cooled heat dissipation, cooling the warning device 3. The whole process is automatic heat dissipation, avoiding high-temperature overload damage to the warning device 3 and improving the service life of the warning device 3.

[0041] In order to provide a function of waterproofing and dustproofing for the protection box 1 without affecting the normal operation of the fans 16, a connecting plate 17 is fixedly provided on the top side of the top cover 4. A diversion plate 18 is fixedly provided on the top side of the connecting plate 17. A wind baffle 19 is detachably connected to the bottom side of the diversion plate 18. A dust-proof net plate 20 is detachably connected to one side of the wind baffle 19;

[0042] When it rains, the rainwater flows down along the diversion plate 18 and will not enter the protection box 1. At the same time, due to the function of the wind baffle 19, when it rains and there is wind, the rainwater will not enter the top side of the top cover 4. At the same time, the dust-proof net plate 20 can provide a dust-proof function, avoiding introducing external dust into the interior of the protection box 1 when the fans 16 are working.

[0043] In order to improve the diversion performance and avoid the situation of water accumulation at the top of the diversion plate 18, the diversion plate 18 is arranged in an umbrella-shaped structure.

[0044] For the convenience of opening the top cover 4, overhauling and replacing the warning device 3 inside the protection box 1, and enhancing the anti-theft security, a locking mechanism is provided, including: a slide bar 21. A chute is provided on the top side of the protection box 1, and the slide bar 21 is slidably connected to the inner side of the chute. One side of the slide bar 21 is fixedly connected to one side of the top cover 4. A fixed block 22 is fixedly provided on one side of the protection box 1. A connecting groove is provided inside the fixed block 22. One side of the slide bar 21 is located inside the connecting groove. A threaded hole is fixedly provided inside the connecting groove, and the threaded hole penetrates through the slide bar 21. A threaded rod 23 is rotatably connected to the inside of the threaded hole by threads. A knob 24 is fixedly provided on one side of the threaded rod 23. An intelligent lock 25 is fixedly provided on one side of the protection box 1. A lock catch matching the intelligent lock 25 is fixedly provided on one side of the top cover 4;

[0045] During use, rotate the knob 24 to drive the threaded rod 23 to rotate, so that the threaded rod 23 disengages from one side of the slide bar 21. At the same time, the maintenance personnel are required to input the password to open the intelligent lock 25, and then only need to gently push the top cover 4, and cooperate with the slide bar 21 to slide on the top side of the protection box 1, then the top of the protection box 1 can be opened to overhaul, replace and maintain the internal warning device 3. The setting of the intelligent lock 25 improves the use safety, avoids non-staff members from touching the warning device 3, and facilitates the opening of the top cover 4.

[0046] To provide a power supply function, a storage battery is fixedly provided on one side of the protection box 1. A solar photovoltaic panel is electrically connected to one side of the storage battery through a wire. One side of the controller 5 is electrically connected to the storage battery through a wire. The setting of the solar photovoltaic panel enables the storage battery to store electricity and be supplemented by solar energy, which is environmentally friendly and safe.

[0047] To enhance the heat conduction of the placement plate 2, the inner side of the placement plate 2 is provided with a mesh hollow structure, and the placement plate 2 is made of heat-conducting insulating elastic rubber;

[0048] The heat-conducting insulating elastic rubber has good heat-conducting ability and high-grade voltage resistance. This type of product is easy to install, conducive to automated production and product maintenance, and is a new material with excellent craftsmanship and practicality.
