Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet protection technology, and in particular to a protection mechanism and its power distribution switch control equipment. Background Technology

[0002] In power distribution systems, the safety protection of switch control equipment (such as distribution cabinets, control boxes, etc.) is of paramount importance.

[0003] Since equipment typically requires cabling for power transmission or signal connection, cabinets often have cable inlets for cables to pass through. However, there are often gaps between the cables and the cable inlets, which can become channels for small animals (such as rats, snakes, insects, etc.) to enter the cabinet. Once animals invade the power distribution equipment, they can easily damage the electrical equipment, leading to equipment failure, electrical fires, or even power system paralysis, seriously affecting power supply safety and stability. To address this, we propose a protective mechanism and its power distribution switch control equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a protective mechanism and its power distribution switch control device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective mechanism, comprising:

[0032] Compared with the prior art, the technical effects of this utility model are as follows:

[0033] This invention utilizes a covering mechanism fixed to the bottom of the cabinet. After the cable passes through the inlet and completes the wiring, the air intake mechanism inflates the airbag ring inside the covering mechanism until the inner wall of the airbag ring presses against the cable passing through the inlet.

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] This utility model provides, for example Figures 1-3The protective mechanism shown includes an inlet 102, a covering mechanism, an air intake mechanism, an exhaust mechanism, and a fixing mechanism. The inlet 102 is located at the bottom of the cabinet. The covering mechanism is located below the inlet 102. The air intake mechanism is connected to the covering mechanism, and the exhaust mechanism is connected to the covering mechanism. The fixing mechanism is located between the covering mechanism and the cabinet. By using the covering mechanism fixed at the bottom of the cabinet, after the cable passes through the inlet 102 and is completed, the air intake mechanism inflates the airbag ring 302 inside the covering mechanism until the inner wall of the airbag ring 302 abuts against the cable passing through the inlet 102. This prevents animals from entering the cabinet through the gap between the cable and the inlet 102, thus avoiding damage to the electrical equipment inside the cabinet.

[0040] The covering mechanism includes a connecting pipe 301 and an airbag ring 302. The top end of the connecting pipe 301 is fixedly connected to the bottom end of the cabinet. The connecting pipe 301 is positioned opposite the inlet 102. An air intake mechanism is located on the outer wall of the connecting pipe 301, an exhaust mechanism is located on the outer wall of the connecting pipe 301, and a fixing mechanism is located between the connecting pipe 301 and the cabinet. The airbag ring 302 is fixedly connected to the inner wall of the connecting pipe 301. When the cable passes through the inlet 102, it also passes through the airbag ring 302 inside the connecting pipe 301. After the wiring is completed, with the cooperation of the air intake mechanism, the airbag ring 302 inflates and squeezes the outer wall of the cable, so that the inflated airbag ring 302 can prevent external animals from entering the cabinet through the gap between the inlet 102 and the cable.

[0041] The air intake mechanism includes an air intake pipe 401, a first fixed plate 402, a second fixed plate 403, a piston plate 404, a first one-way valve 405, and a second one-way valve 406. The air intake pipe 401 is sequentially fixedly inserted into the outer wall of the airbag ring 302 and the connecting pipe 301. The first fixed plate 402 is fixedly connected to the inner wall of the air intake pipe 401, and the second fixed plate 403 is fixedly connected to the inner wall of the air intake pipe 401. The piston plate 404 is slidably connected to the inner wall of the air intake pipe 401 and is located between the first fixed plate 402 and the second fixed plate 403. In this process, the first one-way valve 405 is installed on one side of the second fixed plate 403, and the second one-way valve 406 is installed on the outer wall of the air intake pipe 401. After the wiring is completed, the piston plate 404 moves in the air intake pipe 401, so that the external air continuously enters between the piston plate 404 and the second fixed plate 403 through the second one-way valve 406, and then enters the airbag ring 302 through the first one-way valve 405, so that the airbag ring 302 slowly inflates until it touches the outer wall of the cable, thereby improving the convenience and stability of the wrapping mechanism.

[0042] A connecting rod 501 is fixedly connected to one side of the piston plate 404. A movable hole 502 is opened on one side of the first fixed plate 402. The connecting rod 501 is movably inserted into the inner wall of the movable hole 502. A convex block 503 is fixedly connected to one end of the connecting rod 501. The shape of the convex block 503 allows the operator to move the convex block 503 even after it abuts against the first fixed plate 402. Thus, the piston plate 404 moves under the connection of the connecting rod 501, allowing the intake mechanism to work.

[0043] The exhaust mechanism includes an exhaust pipe 601, a sealing cap 602, and a rubber plug 603. The exhaust pipe 601 is sequentially fixedly inserted into the outer wall of the airbag ring 302 and the connecting pipe 301. The sealing cap 602 is threaded onto the outer wall of the exhaust pipe 601. The rubber plug 603 is fixedly connected to the inner wall of the sealing cap 602 and inserted into the inner wall of the exhaust pipe 601. When wiring is required, the sealing cap 602 can be unscrewed from the outer wall of the exhaust pipe 601 to allow air in the airbag ring 302 to be discharged through the exhaust pipe 601, thus facilitating cable passage. At the same time, the rubber plug 603 allows the sealing cap 602 to be tightened on the outer wall of the exhaust pipe 601, and the rubber plug 603 can be inserted into the exhaust pipe 601 to seal it, preventing air in the airbag ring 302 from being discharged through the exhaust pipe 601, thereby improving the stability of the covering mechanism.

[0044] The fixing mechanism includes a connecting ring 703, a socket 701, a bolt 702, and a locking nut 704. The connecting ring 703 is fixedly sleeved on the outer wall of the connecting pipe 301. The socket 701 is opened at the bottom of the cabinet and the connecting ring 703. The bolt 702 is movably inserted into the inner wall of the socket 701. The locking nut 704 is threaded onto the outer wall of the bolt 702. By passing the bolt 702 through the two sockets 701 in sequence and then tightening the locking nut 704 on the outer wall of the bolt 702, the connecting ring 703 is fixed to the cabinet, thereby fixing the connecting pipe 301 to the cabinet. This improves the stability of the covering mechanism. At the same time, this modular design of the covering mechanism allows the cabinet to be equipped with the covering mechanism according to actual needs. For example, in some relatively enclosed indoor environments, where there is no need to worry about animals entering, the covering mechanism can be omitted.

[0045] This utility model also provides a power distribution switch control device, including the protective mechanism of any one of the above.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
