A protection system for an outdoor power distribution cabinet

Abstract

The present invention relates to the technical field of power distribution cabinets, and specifically to a protection system for an outdoor power distribution cabinet. A detection module is used to obtain water flow conditions, and the water flow conditions are sent to a signal processing module. The signal processing module sends instructions to a guide module based on the received water flow conditions to guide the water flow. Specifically, when the water level is high, the water level plate moves upward under the action of buoyancy, and at the same time, a resistance plate moves upward. The upward movement of the resistance plate pushes the moving rod to move, and a reset spring is compressed, then two groups of contact switches are triggered, so that the power distribution cabinet is powered off. When the water flows from one side of the base, it enters the water inlet, and the water level in the water storage chamber reaches a certain position, then the float plate rises to push the guide plate out, and the guide plate guides the water flow to prevent the water flow from directly impacting the base, reduce erosion of the base, and at the same time reduce splashing water droplets, thereby reducing the risk of damage to the power distribution cabinet.

Description

Technical Field

[0001] The present invention relates to the technical field of distribution cabinets, and particularly to a protection system for an outdoor distribution cabinet. Background Art

[0002] The distribution cabinet is an important part of the power system. In daily use, the distribution cabinets are widely distributed. Some distribution cabinets are distributed outdoors. In order to prevent water ingress, a base is generally poured with cement at the bottom of the outdoor distribution cabinet. The base can protect against accumulated water at a certain water level, ensuring that the distribution cabinet does not come into contact with the accumulated water. The patent application with the application number CN202010032079.1 filed by our company proposed a water level protection device for a distribution cabinet. After the first expansion member encounters water, it absorbs water and expands, pushing the cover plate upward. The lifting device on the cover plate moves upward to lift the distribution cabinet to a height higher than the water level of the accumulated water, preventing the accumulated water from entering the interior of the distribution cabinet.

[0003] However, the applicant found in practice that the prior art has at least the following problems:

[0004] When heavy rain occurs, a large amount of water flow is often formed. The flow of the water flow directly impacts and scours the base of the distribution cabinet, eroding the base and at the same time, the splashing water droplets may cause damage to the distribution cabinet.

[0036] The detection module 201 obtains the water flow situation and sends the water flow situation to the signal processing module 102. The signal processing module sends an instruction to the guiding module 301 according to the received water flow situation to guide the water flow.

[0037] In some optional specific embodiments, the power distribution module 101 includes a base 402 installed on the ground. There is a preset height between the top surface of the base 402 and the ground, and a power distribution cabinet 401 is installed on the top surface of the base 402.

[0038] In some optional specific embodiments, the detection module 201 includes a water level detection unit 202, the water level detection unit 202 includes two groups of guide holes 601 opened in the distribution cabinet 401, the two groups of guide holes 601 are arranged opposite to each other, a moving rod 604 is adapted to be installed in the guide hole 601, a contact switch 602 is also installed in the guide hole 601, a reset spring 603 is installed between the moving rod 604 and the inner wall of the guide hole 601, the moving rod 604 is connected to an inclined plate 606, the inclined plate 606 is adapted to be connected to a resistance plate 704, the resistance plate 704 is connected to a connecting rod 703, a mounting sleeve 701 is installed on the side wall of the base 402, the connecting rod 703 is adapted to be installed in the mounting sleeve 701, a water level plate 702 is connected to the top of the connecting rod 703, the water level plate 702 has buoyancy, and the height of the water level plate 702 is lower than the upper surface of the base 402. When in use, when the water level is high, the water level plate 702 moves upward under the action of buoyancy, and the contact plate 704 moves upward at the same time. The upward movement of the contact plate 704 pushes the moving rod 604 to move, and the reset spring 603 is compressed, and the two sets of contact switches 602 are triggered, so that the distribution cabinet 401 is powered off.

[0039] In some optional specific embodiments, the detection module 201 further includes a flow direction detection unit 203, and the flow direction detection unit 203 includes a baffle 605, and the baffle 605 is installed at the end of the moving rod 604. When the water flows toward the baffle 605, it impacts the baffle 605, pushing one group of moving rods 604 to move, so that one group of contact switches 602 is triggered to determine the flow direction of the water.

[0040] In some optional specific embodiments, the guide unit 303 includes a receiving groove 507 opened on the ground, and a guide plate 506 is adapted to be installed in the receiving groove 507.

A floating plate 503 is installed in the water storage cavity 502, and the floating plate 503 is fixedly connected to a support rod 504. When water flows from one side of the base 402, it enters the water inlet 501. When the water level in the water storage cavity 502 reaches a certain position, the floating plate 503 rises and pushes out the deflector plate 506.

[0043] In some optional specific embodiments, a shielding portion 403 is installed at the top of the water inlet 501, and the shielding portion 403 is integrally formed with the base 402.

[0044] The working principle of the present invention: The detection module 201 obtains the water flow condition and sends the water flow condition to the signal processing module 102. The signal processing module sends an instruction to the guiding module 301 according to the received water flow condition to guide the water flow; specifically, when the water level is relatively high, the water level plate 702 moves upward under the buoyancy force, and at the same time, the contact plate 704 moves upward. The upward movement of the contact plate 704 pushes the moving rod 604 to move, and the return spring 603 is compressed, so that the two contact switches 602 are triggered, causing the power distribution cabinet 401 to cut off the power; when water flows from one side of the base 402, it enters the water inlet 501. When the water level in the water storage cavity 502 reaches a certain position, the floating plate 503 rises and pushes out the deflector plate 506. The deflector plate 506 guides the water flow, avoiding the direct impact of the water flow on the base 402, reducing the erosion of the base 402, and at the same time reducing the splashing water droplets, reducing the risk of damage to the power distribution cabinet 401.
