Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rodent prevention technology for ring main units, and specifically relates to a rodent prevention device for ring main units. Background Technology
[0002] In power systems, ring main units are an important type of power distribution equipment, widely used in urban power grids, industrial and mining enterprises, and other places, undertaking key tasks such as distributing electrical energy and controlling the on / off state of circuits.
[0003] However, ring main units (RMS) often face the problem of rodent infestation during operation, posing a serious threat to the safe and stable operation of the power system. Rats have a natural instinct to gnaw, and their teeth grow extremely quickly, requiring them to constantly gnaw on hard objects to wear them down. Cables, insulation materials, and other components inside the RMS often become targets for rodent chewing. Once cables are damaged by rodents, it can lead to short circuits, causing power outages and disrupting normal production and daily life. Furthermore, the high-temperature arc generated by a short circuit can also cause fires, posing a significant threat to the surrounding environment and human safety. In addition, rodent activity inside the RMS can damage the mechanical structure of the equipment, leading to malfunctions, increased maintenance costs, and longer power outage times.
[0004] Currently, traditional rodent control methods have certain limitations. For example, while rodent-proof netting can prevent rats from entering ring main units to some extent, the mesh size of the netting is difficult to control precisely. If it is too small, it may affect the heat dissipation of the ring main unit; if it is too large, it will not effectively prevent rats. Moreover, rodent-proof netting is easily corroded and damaged when exposed to the outdoors for a long time, reducing its rodent-proof effect. Therefore, this application proposes a rodent-proof device for ring main units. Utility Model Content

[0025] 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.
[0026] This embodiment provides a rodent-proof device for a ring main unit, the structural diagram of which is shown below. Figures 1-4 As shown, this device is mainly used in the ring mesh cabinet 1 to prevent rats from entering the interior of the ring mesh cabinet 1 and causing damage. It includes a base 2 installed at the bottom of the ring mesh cabinet 1. The base 2 is generally rectangular in shape and has a hollow interior, providing space for rats to enter and for subsequent handling.
[0027] In this embodiment, inlet 3 is provided on both ends of the base 2, and two inlets 3 are provided on each end face, distributed at both ends of the end face of the base 2. The size of the inlet 3 is designed to allow a mouse to pass through, with a width and height ranging from 8 to 12 cm, ensuring that the mouse can pass through smoothly into the interior of the base 2.
[0028] Furthermore, a drawer 4 is provided in the middle of the base 2, which can be pulled out horizontally from one side of the base 2. Through slots 8 are provided on both side walls of the drawer 4, centrally located and offset from the inlet 3. This offset design requires a specific path for a mouse to reach the drawer 4 after entering the base 2, increasing the difficulty of escape.
[0029] Furthermore, a box 9 is located in the middle of the bottom wall inside drawer 4, containing a rodent attractant 10. The rodent attractant 10 emits an odor that attracts mice. The rodent attractant 10 can be a food with a strong odor, such as peanut butter or cheese, or it can be a specially formulated chemical rodent attractant 10. Its function is to attract mice into drawer 4. A sticky mouse trap 7 is also laid on the bottom wall inside drawer 4. The sticky mouse trap 7 has strong adhesive properties; when a mouse enters drawer 4 and steps on the sticky mouse trap 7, it will be firmly stuck and unable to escape.
[0030] Furthermore, in this embodiment, a handle 11 is provided on the outer end face of the drawer 4 that allows it to be pulled out from the base 2. At the same time, a pair of limiting plates 13 are provided on the inner wall of the base 2. The pair of limiting plates 13 fit against the outer side of the drawer 4, which restricts the position of the drawer 4, prevents the drawer 4 from shaking inside the base 2, and ensures the stability of the drawer 4.
[0031] As a preferred technical solution in this embodiment, a first channel 5 is provided at both ends of the base 2 corresponding to the inlet 3, and a second channel 6 is provided between the two sides of the drawer 4 and the first channel 5. The second channel 6 is connected to the first channel 5, and the second channel 6 is connected to the internal space of the drawer 4 through the through groove 8. After the mouse enters from the inlet 3, it can smoothly pass through the first channel 5 and the second channel 6 to enter the interior of the drawer 4. Moreover, this channel setting forms a circuitous path, which increases the difficulty for the mouse to escape from the base 2.
[0032] In this embodiment, a ramp 12 is provided inside the first channel 5. The ramp 12 is distributed upwards from the inlet 3 towards the second channel 6. The higher end of the ramp 12 is large enough to allow a mouse to pass through between it and the inner top wall of the base 2. The lower end of the ramp 12 is sealed to the inner bottom wall of the first channel 5, and both sides of the ramp 12 are sealed to the inner side walls of the first channel 5. The higher end of the ramp 12 is left open between it and the inner bottom wall of the first channel 5. This design requires the mouse to climb up the ramp 12 to enter the second channel 6 after entering the first channel 5 through the inlet 3. After entering the second channel 6, the open space between the higher end of the ramp 12 and the inner bottom wall of the first channel 5 restricts the mouse's movement path and prevents the mouse from escaping from the inlet 3.
[0033] Working principle:
[0034] When mice move around the ring mesh cabinet 1, they are attracted by the scent emitted by the rodent bait 10 inside the drawer 4, box 9. The mice first enter the first passage 5 through the inlet 3 on the end face of the base 2. Inside the first passage 5, because the ramp 12 is distributed upwards from the inlet 3 towards the second passage 6, the mice climb up the ramp 12 and then enter the second passage 6 through the gap between the higher end of the ramp 12 and the first passage 5. Next, the mice enter the drawer 4 through the slot 8 on the side wall of the drawer 4. After entering the drawer 4, the mice step on the sticky mouse trap 7, which traps them, preventing them from escaping and thus preventing them from entering the ring mesh cabinet 1. The drawer 4 can then be pulled out of the base 2 to remove the trapped mice.
[0035] All technical features in this embodiment can be freely combined according to actual needs.
[0036] 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.
