Description

Technical Field

[0001] This utility model relates to the field of medium-voltage switchgear, and more specifically, to a medium-voltage switchgear that facilitates component wiring. Background Technology

[0002] Medium-voltage switchgear is suitable for power plants, petroleum, chemical, metallurgical, textile, high-rise building and other industries for power transmission, distribution and power conversion. Patent publication number CN208478900U discloses a low-voltage switchgear that facilitates wiring, including a cabinet. Inside the cabinet is a cable tray, and inside the cable tray are two horizontally spaced electrical component mounting plates. A cable tray is located directly below each electrical component mounting plate. Ventilation holes are evenly distributed on both side walls of the cable tray. Shock-absorbing mechanisms are provided at the four corners of the top and bottom of the cable tray. A pulley is fixedly connected to the bottom of the first cylinder. Wiring grooves are evenly distributed on the surface of the cable tray. Cooling fans are symmetrically arranged in the center of the bottom of the cabinet. This utility model facilitates the installation and wiring of electrical components and also has dustproof and heat dissipation functions.

[0003] In existing technologies, during component wiring, since each electronic component has a different size and specification, the actual installation requires reasonable wiring arrangement based on its size and location. The aforementioned switch cabinet uses two fixed mounting plates for component installation, which results in the component positions being basically fixed and making it impossible to adjust the height and position appropriately to optimize the wiring arrangement. For example, some components are large, and the same installation space may result in less space for wiring arrangement, forcing the wires to be wound up, which may affect heat dissipation and service life, thus reducing the overall practicality of the switch cabinet. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a medium-voltage switch cabinet that facilitates component wiring. It can adjust the height of the electronic component mounting plate to accommodate the installation needs of various components of different sizes and specifications. Furthermore, by adjusting the height of the wiring board, it provides more suitable space for cable arrangement, thereby further optimizing the cable arrangement and improving the overall practicality of the device.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A medium-voltage switch cabinet for easy component wiring includes a cabinet, a cable tray slidably mounted inside the cabinet, an extension box fixedly mounted on the inner side of the cable tray, a sliding groove provided on the side of the extension box, a slider slidably mounted inside the sliding groove, a component mounting plate fixedly mounted on the side of the slider, a toothed plate slidably mounted inside the component mounting plate, and a cable tray fixedly mounted at the bottom end of the toothed plate.

[0009] Furthermore, a screw is rotatably mounted inside the sliding groove, and a rotating wheel is fixedly mounted at one end of the screw.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Example 1:

[0031] Please see Figure 1-5 A medium-voltage switch cabinet for easy component wiring includes a housing 1. A cable tray 2 is slidably installed inside the housing 1. An extension box 3 is fixedly installed on the inner side of the cable tray 2. A sliding groove 301 is provided on the side of the extension box 3. A slider 401 is slidably installed inside the sliding groove 301. A component mounting plate 4 is fixedly installed on the side of the slider 401. A toothed plate 501 is slidably installed inside the component mounting plate 4. A cable tray 5 is fixedly installed at the bottom end of the toothed plate 501.

[0032] It should be noted that the structure of the enclosure 1 in this application is basically the same as that of the switch cabinet in the prior art. Therefore, the cable tray 2 can slide out inside it, which is a mature existing technology. Therefore, in this application, the relevant structure required for the cable tray 2 to slide out will not be described in detail.

[0033] A screw 302 is rotatably mounted inside the sliding groove 301. A rotating wheel 303 is fixedly mounted at one end of the screw 302. There are two screws 302. A limiting disk 304 is rotatably mounted between the two rotating wheels 303. The limiting disk 304 is rotatably mounted inside the extension box 3. The screw 302 and the slider 401 are threadedly connected to each other.

[0034] Specifically, the slider 401 is slidably installed inside the sliding groove 301, which allows the slider 401 to move up and down as the screw 302 is driven by the thread. During the movement, it has a limiting function to prevent it from deviating from other positions. In addition, the limiting plate 304 ensures the rotation of the two rotating wheels 303, which also has a limiting function, ensuring the original rotation of the screw 302.

[0035] A turntable 403 is rotatably mounted in the middle of the component mounting plate 4. A connecting rod 404 is integrally formed at both the left and right ends of the turntable 403. A worm gear 405 is integrally formed at the outer end of the connecting rod 404. A worm wheel 406 meshes with the surface of the worm gear 405. Limiting posts 407 are integrally formed on both the front and rear sides of the worm wheel 406. The limiting posts 407 are rotatably mounted inside the component mounting plate 4. The surface of the worm wheel 406 meshes with the toothed plate 501. Several wire grooves are integrally formed on the surface of the cable tray 5. Several bolt interfaces 402 are fixedly mounted on both the upper and lower sides of the component mounting plate 4.

[0036] Specifically, the worm gear 405 and worm wheel 406 are used for mutual transmission, and the worm wheel 406 drives the toothed plate 501 to move up and down. This ensures that the two toothed plates 501 can be controlled by a turntable 403, achieving the purpose of one-to-two transmission and facilitating operation. The rotation of the limit post 407 inside the component mounting plate 4 can limit the rotation of the worm wheel 406, thereby ensuring the transmission stability of the intermediate transmission component.

[0037] The working principle of this utility model is as follows: First, the electronic components are fixedly connected to the bolt interface 402 using bolts and other connectors. The position between the two component mounting plates 4 is adjusted according to the size of the electronic components. The rotating wheel 303 drives the screw 302 to rotate, which, together with the slider 401, realizes the lifting and lowering movement of the component mounting plate 4 until it is moved to the appropriate position and then stops. Then, during the wiring process, in order to prevent the wire from being too long or too short, the wiring plate 5 is adjusted to the appropriate position. The rotating disk 403 drives the worm gear 405, which in turn drives the worm wheel 406 to rotate. The other side of the rotating worm wheel 406 drives the toothed plate 501 to adjust the overall position of the wiring plate 5 until the wire arrangement is suitable for installation.

[0038] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
