Technical Field

[0001] The present application relates to the technical field of electric energy meter boxes, and in particular to an electric energy meter box. Background Art

[0002] The electricity meter box is a device used to measure and meter electricity consumption. It is widely used in power supply and electricity management systems. The electricity meter box can provide accurate electricity metering and monitoring functions, which helps to monitor electricity usage in real time.

[0003] In the related art, the electric energy meter box includes a box body, in which a plurality of electrical components are arranged, and the electrical components can realize the basic functions of the electric energy meter box. A plurality of heat dissipation holes are opened on the side of the box body, and the plurality of heat dissipation holes provide air flow inside and outside the box body.

[0004] Since part of the electricity meter box is installed outdoors, when there is heavy rain outdoors, rainwater may enter the box through the heat dissipation holes, causing water accumulation inside the box, affecting the normal operation of the electrical components inside the box, and even causing some electrical components to malfunction, rendering the electricity meter box inoperable. Summary of the invention

[0005] In order to improve the problem that rainwater easily enters the interior of the box through the heat dissipation holes during heavy rain, the present application provides an electric energy metering box.

[0006] The present application provides an electric energy meter box, which adopts the following technical solution:

[0007] An electric energy meter box comprises a box body, a plurality of heat dissipation holes are provided on the box body, a receiving cavity connected to the heat dissipation holes is provided on the box body, a support rod is rotatably connected in the receiving cavity, a waterproof cloth is provided on the support rod, the waterproof cloth can cover the heat dissipation holes, and people can drive the support rod to rotate.

[0008] By adopting the above technical solution, the waterproof cloth is set on the support rod, and the support rod is rotatably connected to the accommodating cavity. When people drive the support rod to rotate, the support rod can move the waterproof cloth in the accommodating cavity. Since the accommodating cavity is connected to the heat dissipation holes, the waterproof cloth can block the heat dissipation holes so that the heat dissipation holes will not be connected to the inside of the box. When encountering heavy rain, the waterproof cloth blocks the heat dissipation holes, making it difficult for rainwater to enter the inside of the box through the heat dissipation holes, making it difficult for rainwater to affect the electrical components inside the box, so that the electric energy meter box can operate stably.

[0009] Optionally, the waterproof cloth is provided with a water absorption strip, the box body is provided with a water flow hole connected to the accommodating cavity, the opening of the water flow hole is connected to the water absorption strip, when the water absorption strip absorbs a certain amount of water, the water absorption strip can drive the waterproof cloth to cover the heat dissipation hole.

[0010] By adopting the above technical solution, a water flow hole connected to the accommodating cavity is opened on the box body, so that rainwater can flow from the water flow hole into the accommodating cavity, so that the water absorption strip can absorb a certain amount of rainwater, and the weight of the water absorption strip itself is increased. The water absorption strip can drive the waterproof cloth to move, and then the waterproof cloth can cover the heat dissipation holes, so that the waterproof cloth can automatically rotate on the support rod, so that when a certain amount of rainwater accumulates, the heat dissipation holes can be covered, and people do not need to rotate the support rod when it rains.

[0011] Optionally, a gear block is provided on the support rod, and a gear bar is provided on the box body, and the gear bar is meshed with the gear block. When the waterproof cloth completely blocks the heat dissipation holes, the gear bar blocks the water flow holes.

[0012] By adopting the above technical solution, the gear block is on the support rod, and the gear bar is meshing with the gear block. When the waterproof cloth moves, the support rod can rotate, so that the support rod drives the gear bar to move, and the gear bar blocks the water hole, making it difficult for rainwater to continue to flow from the water hole into the accommodating cavity.

[0013] Optionally, a through hole connected to the accommodating cavity is provided on the box body, a dovetail groove is provided on the water absorbing strip, and a dovetail block is provided on the waterproof cloth. When the dovetail block is separated from the dovetail groove, the water absorbing strip can be separated from the accommodating cavity through the through hole.

[0014] By adopting the above technical solution, the dovetail block is inserted into the dovetail groove so that the water absorbent strip can be fixed on the waterproof cloth. Since the perforation is connected to the accommodating cavity, the water absorbent strip can be taken out from the perforation. After the heavy rain is over, people can replace the water absorbent strip so that the water absorbent strip can absorb water again, so that the water absorbent strip will not absorb a small amount of water and drive the waterproof cloth to move, thereby ensuring the water absorption capacity of the water absorbent strip.

[0015] Optionally, a fixed cover is slidably connected to the box body, and the fixed cover can completely cover the perforation. A fixing component is provided on the fixed cover, and the fixing component is used to limit the sliding of the fixed cover at the perforation.

[0016] By adopting the above technical solution, a fixing component is provided on the fixing cover, so that the fixing component can restrict the fixing cover, and the fixing cover can completely cover the perforation, making it difficult for debris to enter the accommodating cavity through the perforation, so that the water absorbent strip can fall smoothly.

[0017] Optionally, a first magnet is provided on the waterproof cloth, and a second magnet is provided in the accommodating cavity. When the first magnet attracts the second magnet, the waterproof cloth abuts against an inner wall of the accommodating cavity where the heat dissipation hole is provided.

[0018] By adopting the above technical solution, the first magnet absorbs the second magnet, so that the waterproof cloth can abut the inner wall of the accommodating cavity, allowing the waterproof cloth to stably cover the heat dissipation holes, reducing the possibility of the waterproof cloth moving when air flows in the heat dissipation holes, and enhancing the shielding effect of the waterproof cloth on the heat dissipation holes.

[0019] Optionally, a sliding groove is provided on the box body, the fixed cover slides in the sliding groove, the second magnet is slidably connected to the inner wall of the accommodating cavity, and a accommodating groove is provided on the fixed cover. When one end of the second magnet is located in the accommodating groove, the fixed cover can cover the perforation, and when the first magnet attracts the second magnet, the second magnet is separated from the accommodating groove.

[0020] By adopting the above technical solution, the fixed cover slides in the sliding groove, and one end of the second magnet can be inserted into the receiving groove, so that the second magnet can restrict the fixed cover. When the first magnet attracts the second magnet, the second magnet is separated from the receiving groove, so that the fixed cover can move in the sliding groove. When the waterproof cloth covers the heat dissipation hole, the first magnet on the waterproof cloth can unlock the fixed cover, so that the fixed cover can slide smoothly in the sliding groove.

[0021] Optionally, a third magnet capable of attracting the second magnet is provided in the receiving groove, the magnetic force of the third magnet on the second magnet is smaller than the magnetic force of the first magnet on the second magnet, and the third magnet can drive the second magnet to be inserted into the receiving groove.

[0022] By adopting the above technical solution, when the waterproof cloth does not block the heat dissipation hole, the third magnet can absorb the second magnet, allowing one end of the second magnet to be inserted into the receiving groove, so that the second magnet locks the fixed cover; when the waterproof cloth blocks the heat dissipation hole, the magnetic force of the third magnet on the second magnet is smaller than the magnetic force of the first magnet on the second magnet, and the first magnet absorbs the second magnet, allowing the second magnet to be separated from the receiving groove, so that the second magnet does not lock the fixed cover, and the second magnet unlocks the fixed cover.

[0023] Optionally, the fixing assembly includes a fixing bar, which is rotatably connected to a fixing cover, and the box body is provided with a fixing groove for inserting the fixing bar. When the fixing bar is inserted into the fixing groove, the fixing cover blocks the perforation.

[0024] By adopting the above technical solution, the fixing bar is rotatably connected to the fixing cover, and the fixing bar is inserted into the fixing groove, so that the groove wall of the fixing groove restricts the fixing bar, so that the fixing bar can be fixed to the box body, and the fixing cover can stably cover the through hole, making it difficult for debris to enter the accommodating cavity through the through hole.

[0025] Optionally, a solar panel is provided on the box, a battery is electrically connected to the solar panel, and electrical components are provided in the box, and the battery is used to supply electrical components.

[0026] By adopting the above technical solution, the solar panels are arranged on the box. When it is sunny, the solar panels can convert solar energy into electrical energy.

The rotation groove 221 is a regular hexagon, which is convenient for people to rotate the support rod 22 through tools.

[0044] Reference Figure 3 , Figure 4 and Figure 5 A waterproof cloth 23 is fixedly connected to the support rod 22, and a dovetail block 231 is fixedly connected to the end surface of the waterproof cloth 23 away from the support rod 22. A water-absorbing strip 24 is provided on the waterproof cloth 23, and a dovetail groove 241 is provided on the end surface of the water-absorbing strip 24. The dovetail groove 241 penetrates the end surfaces of the water-absorbing strip 24 on opposite sides, and the dovetail block 231 is inserted into the dovetail groove 241. The waterproof cloth 23 can be wrapped around the support rod 22. When the waterproof cloth 23 is located in the accommodating cavity 2, the waterproof cloth 23 can shield the heat dissipation hole 13, reducing the possibility of rainwater entering the accommodating cavity 2 from the heat dissipation hole 13.

[0045] Reference Figure 2 and Figure 3 The box body 1 is provided with a water flow hole 14 connected to the placement cavity 21.
