Description

Technical Field

[0001] The present invention relates to the technical field of power meter boxes, in particular to a power meter box with a protection mechanism. Background Art

[0002] The electricity meter box is an important device for measuring electric energy in the power system. It is mainly used to measure, record and display the usage of electric energy, which facilitates the power department to settle electricity bills and manage electricity consumption. It is generally composed of a box body, metering instruments (such as smart meters), wiring terminals, circuit breakers and other parts. The box body plays a role in protecting the internal equipment. It has a wide range of application scenarios. In residential communities, it is used to measure the electricity consumption of each household; in industrial and commercial places, it can accurately count the electricity consumption of enterprises and shops. In addition, it is also indispensable in power facilities such as substations and distribution boxes to help monitor and manage energy consumption during the power distribution process.

[0003] Under existing technical conditions, floor-standing electricity meter boxes are usually set at a height of 30 cm to 50 cm from the ground during installation and placement to achieve waterproof protection. However, in extremely harsh weather conditions, especially long-term heavy rain or heavy rainfall, water on the ground will continue to accumulate, and the liquid level will gradually rise, and may eventually exceed the bottom height of the electricity meter box, causing rainwater to seep into the box. Once rainwater comes into contact with electrical components in the box, it will not only cause damage to the electrical components, but may also cause safety hazards such as leakage. At the same time, some rainwater will be violently hit on the heat dissipation holes of the electricity meter box under the action of strong winds, and rainwater will more easily enter the box through the heat dissipation holes, causing damage to electrical components, which will seriously affect the stable operation of the power system.

[0004] For this reason, we propose an electric power metering box with a protection mechanism. Summary of the Invention

[0005] (1) Technical problems solved

[0006] In response to the shortcomings of the existing technology, the present invention provides an electricity meter box with a protective mechanism, which solves the problem that in the case of long-term heavy rain or heavy rainfall, water on the ground will continue to accumulate, the liquid level will gradually rise, and may eventually exceed the bottom height of the electricity meter box, causing rainwater to seep into the interior of the box and rainwater to enter the interior of the box through the heat dissipation holes, causing damage to electrical components.

When the winding shaft 441 collects the wire rope 445, it can drive the auxiliary block 42 to move upward, drive the foldable waterproof cover 43 to unfold, and achieve a protective effect.

[0043] Among them, the drainage component 47 includes a drainage hole 474 opened at the bottom of the exhaust hole 46, the inner wall of the auxiliary block 42 is provided with a collection chamber 476, the drainage hole 474 is connected to the collection chamber 476, the inner wall of the collection chamber 476 is installed with a water level sensor 475, a pump body 471 is installed on one side of the auxiliary block 42, the water level sensor 475 is connected to the pump body 471 by wires, the output end and the input end of the pump body 471 are respectively fixedly connected with a drainage pipe 473 and a suction pipe 472, and the other end of the suction pipe 472 extends into the collection chamber. In the collecting chamber 476, the other end of the drain pipe 473 passes through the upper cover 2 and extends from the upper cover 2. Through the above components, when rainwater hits the auxiliary block 42 and enters the exhaust hole 46, it will enter the collecting chamber 476 through the drain hole 474 in the exhaust hole 46 for collection. When the water level sensor 475 detects that the water level in the collecting chamber 476 is too high, the pump body 471 starts working, and the pump body 471 sucks the rainwater in the collecting chamber 476 through the suction pipe 472 and discharges it through the drain pipe 473.

[0044] Among them, the sealing component 48 includes two cavities 1 483 and 2 484 opened in the inner wall of the auxiliary block 42. The two cavities 1 483 are connected to the 2 484.

The supporting wheel 410 on the auxiliary block 42 can contact the surface of the power metering box 1 to achieve a supporting effect and ensure the stability of the movement. After moving to the appropriate position, the cylinder 481 is turned on, and the cylinder 481 The piston block 482 is driven to move, pushing the gas in the cavity 1 483 into the cavity 2 484, and then the air bag 485 is expanded, tightly fitting with the outer surface of the power meter box 1 to achieve a sealing effect, reducing the entry of rainwater between the folding waterproof cover 43 and the power meter box.

When heat dissipation is in progress, the cooling fan can blow air downward from the upper cover 2, and the gas can be discharged through the exhaust hole 46 on the surface of the mounting plate 45. When the folding waterproof cover 43 completely blocks the exhaust hole 46, the gas discharged from the exhaust hole 46 can enter the auxiliary hole 412 and be discharged through the auxiliary exhaust pipe 411.

[0048] In addition, when the exhaust hole 46 is not completely blocked, rainwater will hit the mounting plate 45 and enter the exhaust hole 46 on the surface of the mounting plate 45. The rainwater flows into the bottom of the trapezoidal exhaust hole 46 and flows into the collecting chamber 476 in the mounting plate 45 through the drainage hole 474. When the water level sensor 475 detects that the water level in the collecting chamber 476 is too high, the pump body 471 starts working, and the pump body 471 sucks away the rainwater in the collecting chamber 476 through the suction pipe 472 and discharges it through the drain pipe 473.
