Abstract

The application discloses a stretchable and adjustable rainproof shed for an outdoor terminal box, which is characterized in that: a rocker is rotated to drive a screw rod to rotate inside a bearing; the screw rod has opposite threads at two ends thereof and is screwed with a screw rod nut; when the screw rod is rotated, the screw rod nut is moved away from the screw rod in a direction away from each other on the outer surface of the screw rod, thereby driving a connecting plate and the rainproof shed to extend out of an adjusting groove, so that the rainproof shed can increase the shielding area of the terminal box; after the rocker is reversely rotated, the two screw rod nuts are moved towards each other on the outer surface of the screw rod, thereby enabling the connecting plate to drive the rainproof shed to enter the inside of the terminal box; when rainwater accumulates, evaporative liquid is extruded from the inside of a liquid storage pipe to the inside of a cooling box body and is in contact with metal cooling fins; when electric elements in the terminal box work, heat generated thereby can make the evaporative liquid vaporize, thereby taking away a large amount of heat and playing an auxiliary heat dissipation effect for the electric elements.

Description

Technical Field

[0001] This invention relates to the field of substation technology, and in particular to a stretchable and adjustable outdoor terminal box rainproof canopy. Background Technology

[0002] Traditional metal-cased terminal boxes have some drawbacks during on-site installation and operation: 1. Because the casing is made of metal, it is prone to leakage and liveness. In addition, because it is a metal structure, cutting, welding and grinding can easily cause perforation, allowing rainwater to enter the electrical live parts through the gaps and small holes at the top.

[0003] A patent document with publication number CN202363760U discloses an outdoor terminal box that forms an airflow channel by providing ventilation openings at the bottom and top of the box. To ensure suitable temperature and humidity inside the box, in addition to being equipped with a fan and an air conditioning forced dehumidification device, a unique "breathing channel" is designed. This channel can effectively achieve ventilation and convection, prevent rainwater from entering, prevent wind and sand from entering, and prevent small animals from entering.

[0004] However, while this outdoor terminal box serves the purposes of rain protection and heat dissipation, it cannot effectively utilize rainwater, and equipping it with a fan for dehumidification and heat dissipation would increase the load on the outdoor terminal box. Summary of the Invention

[0005] The purpose of this invention is to provide a stretchable and adjustable outdoor terminal box rainproof canopy to solve the above-mentioned problems. When water accumulates at the bottom of the terminal box, the buoyancy of the water causes the waterproof board to float on the water surface. The buoyancy of the water compresses the waterproof board, thereby causing the flexible spring to contract. When the height of the waterproof board is higher than the height of the drainage channel, the water accumulated at the bottom of the box will be discharged from the drainage channel, thereby preventing the water level from rising and affecting the electrical components inside the terminal box.

[0006] The present invention achieves the above objectives through the following technical solutions:

[0007] An adjustable outdoor terminal box rainproof canopy includes a terminal box, a base frame at the bottom of the terminal box, and a waterproof plate on the base frame; a box door and a lower box door are provided on the side wall on the same side of the terminal box;

[0008] The terminal box is equipped with a rainproof canopy on top;

[0009] The rainwater collection end of the rain shelter is equipped with a water collection trough, the bottom of the water collection trough is connected to several water collection pipes, the bottom of the water collection pipes is equipped with a telescopic spring, the top of the telescopic springs is equipped with a magnetic slider, and the lower part of the side wall of the water collection pipes is equipped with several drainage holes.

[0010] The bottom of the terminal box is provided with a sealing strip, and several springs are provided on the sealing strip. The other end of the springs is connected to the load-bearing frame, and the height of the load-bearing frame is slightly higher than the lower box door.

[0011] The terminal box is equipped with a mounting bracket on one side of the water collection tank. The mounting bracket is equipped with a partition plate, and the partition plate is equipped with a connecting box. The connecting box is equipped with a liquid storage pipe, which is connected to the cooling box through a connecting pipe. The top of the liquid storage pipe is equipped with a magnetic pressure block, and a movable magnetic ring is provided between the liquid storage pipe and the connecting box. The cooling box is equipped with metal heat sinks.

[0012] The water collection pipe is installed in close contact with the connecting box.

[0013] A further embodiment is that one side wall of the terminal box is provided with several heat dissipation channels, and a pull ring is provided at the lower part of the side wall on the same side as the heat dissipation channels, with drainage grooves on both sides of the pull ring.

[0014] A further solution is that, when there is no water in the water collection pipe, the height of the drain hole is less than the height of the telescopic spring.

[0015] A further embodiment is that the rain shelter has a front rain shield at one end facing the box door, and rain shelters are provided on both sides of the rain shelter near the box door. The rain shelter is fixedly mounted on a connecting plate. The connecting plate is threadedly connected to the lead screw via a lead screw nut. The lead screw is connected to a rocker arm via a bearing. The left and right ends of the lead screw have opposite thread directions. The lead screw is located in an adjustment groove, which is located below the rainwater collection end of the rain shelter.

[0016] A further embodiment is that the movable magnetic ring is slidably connected to the liquid storage tube and the connecting box.

[0017] A further embodiment is that the magnetic slider is slidably connected to the water collection pipe.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. When rainwater accumulates, the evaporator is squeezed from the inside of the storage pipe into the interior of the cooling box and comes into contact with the metal heat sink. When the electrical components inside the terminal box are working, the heat generated will cause the evaporator to vaporize, thereby carrying away a large amount of heat and playing an auxiliary role in heat dissipation for the electrical components.

[0020] 2. When water accumulates at the bottom of the terminal box, the buoyancy of the water will cause the waterproof plate to float on the water surface. The buoyancy of the water will compress the waterproof plate, causing the flexible spring to contract. When the height of the waterproof plate is higher than the height of the drainage trough, the water accumulated at the bottom of the terminal box will be discharged from the drainage trough, thereby preventing the water level from rising and affecting the electrical components inside the terminal box.

[0021] 3. By rotating the rocker arm, the lead screw rotates inside the bearing. Because the threads at the left and right ends of the lead screw are in opposite directions and are threadedly connected to the lead screw nut, the rotation of the lead screw will cause the lead screw nut to move away from each other on the outer surface of the lead screw. This will cause the connecting plate and the canopy to extend out of the adjustment groove, allowing the canopy to increase the coverage area of ​​the terminal box. After rotating the rocker arm in the opposite direction, the two lead screw nuts will move closer to each other on the outer surface of the lead screw, causing the connecting plate to pull the canopy into the interior of the terminal box.

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0038] In any embodiment, such as Figure 1 As shown, an adjustable outdoor terminal box rainproof canopy of the present invention includes a terminal box 1, a base frame 302 at the bottom of the terminal box 1, a waterproof plate 303 on the base frame 302; a box door 2 and a lower box door 3 are provided on the side wall of the terminal box 1 on the same side;

[0039] The terminal box 1 is equipped with a rainproof canopy 4 on its top;

[0040] The rainproof canopy 4 has a rainwater collection trough 401 at the rainwater collection end. The bottom of the rainwater collection trough 401 is connected to several water collection pipes 402. The bottom of the water collection pipes 402 is provided with a telescopic spring 405. The top of the telescopic spring 405 is provided with a magnetic slider 404. The lower part of the side wall of the water collection pipes 402 is provided with several drainage holes 403.

[0041] The bottom of the terminal box 1 is provided with a sealing strip 304, and a number of springs 305 are provided on the sealing strip 304. The other end of the springs 305 is connected to the load-bearing frame 7. The height of the load-bearing frame 7 is slightly higher than the lower box door 3.

[0042] The terminal box 1 is equipped with a mounting bracket 101 located on one side of the water collection tank 401. The mounting bracket 101 is equipped with a partition plate 102, and the partition plate 102 is equipped with a connecting box 104. The connecting box 401 is equipped with a liquid storage pipe 105, which is connected to the cooling box 103 through a connecting pipe 108. The top of the liquid storage pipe 105 is equipped with a magnetic pressure block 107, and a movable magnetic ring 106 is provided between the liquid storage pipe 105 and the connecting box 104. The cooling box 103 is equipped with metal heat sinks 109.

[0043] The water collection pipe 402 is installed in close contact with the connecting box 103.

[0044] The terminal box 1 has several heat dissipation channels 5 on one side wall, and a pull ring 6 is provided on the lower part of the side wall on the same side as the heat dissipation channel 5. Drainage grooves 301 are provided on both sides of the pull ring 6.

[0045] When there is no water in the water collection pipe 402, the height of the drain hole 403 is less than the height of the extension spring 405.

[0046] The rain shelter 4 has a front rain shield 406 at one end facing the box door, and rain shelters 412 on both sides near the box door. The rain shelters 412 are fixedly mounted on the connecting plate 411. The connecting plate 411 is threadedly connected to the lead screw 409 through the lead screw nut 410. The lead screw 409 is connected to the rocker arm 413 through the bearing 408. The left and right ends of the lead screw 409 have opposite thread directions. The lead screw 409 is located in the adjustment groove 407, which is located below the rainwater collection end of the rain shelter 4.

[0047] The movable magnetic ring 106 is slidably connected to the liquid storage tube 105 and the connecting box 104.

[0048] The magnetic slider 404 is slidably connected to the water collection pipe 402.

[0049] The implementation process of this invention is as follows:

[0050] When rainwater drips onto the top of the rain shelter, due to the shape of the rain shelter, the rainwater flows to one side (rainwater collection end) along the upper surface of the rain shelter, thus collecting inside the water collection trough, and then flowing into the inside of the water collection pipe through the connecting hole. The rainwater accumulates on the top of the magnetic slider. When a lot of rainwater accumulates, the gravity of the rainwater will cause the magnetic slider to overcome the friction with the inner wall of the water collection pipe and slide downward inside the water collection pipe.

[0051] As the magnetic slider slides downwards, the movable magnetic ring attracts the side of the magnetic slider that is close to it, causing the movable magnetic ring to slide downwards on the outer surface of the liquid storage tube. Similarly, the magnetic pressure block attracts the side of the movable magnetic ring that is close to it, causing the magnetic pressure block to slide downwards inside the liquid storage tube. This forces the evaporator from inside the liquid storage tube into the interior of the cooling box, where it contacts the metal heat sink. When the electrical components inside the terminal box operate, the heat generated causes the evaporator to vaporize, carrying away a large amount of heat and providing auxiliary cooling for the electrical components.

[0052] When the magnetic slider descends to a height lower than the drain hole, rainwater inside the water collection pipe will be discharged from the drain hole. This causes the magnetic slider to rise under the restoring force of the extension spring, returning to a position higher than the drain hole. As the magnetic slider rises, it drives the movable magnetic ring to slide upward on the outer surface of the liquid storage tube. The movable magnetic ring drives the magnetic pressure block to slide upward inside the liquid storage tube. Under the action of air pressure inside the liquid storage tube, the vaporized liquid will enter the inside of the liquid storage tube through the connecting pipe. After the temperature of the electrical components drops, the liquid will liquefy inside the liquid storage tube due to the cooling effect, thus continuing to provide auxiliary heat dissipation for the electrical components inside the terminal box when rainwater accumulates again.
