Description

Technical Field

[0001] The utility model belongs to the technical field of control cabinets, and in particular relates to an electrical control cabinet for mines. Background Art

[0002] A control cabinet is a device that assembles switchgear, measuring instruments, protective devices, and auxiliary equipment in a closed or semi-enclosed metal cabinet or on a screen according to electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, facilitate maintenance, and not endanger the safety of personnel and surrounding equipment. Mining electrical control cabinets are designed specifically for mining environments.

[0003] Patent No. CN211790028U is a coal mine mining method that uses an electrical control cabinet to drive the rotor through a motor, the rotor drives gear A to rotate, gear A drives gear B to rotate, and gear B drives fan blade A to rotate, so that the electrical control cabinet can quickly discharge the internal hot air, speed up the air exchange of the electrical control cabinet, and at the same time discharge the internal dust from the interior of the electrical control cabinet, thereby reducing the possibility of explosion accidents.

[0004] However, when the electrical control cabinet used in the coal mine in the utility model needs to be repaired or replaced with electronic components inside the control cabinet, since most of these electronic components are fixedly assembled inside the control cabinet, when handling some electronic components located deep inside the cabinet cavity, the relatively small operating space makes it inconvenient for the staff to operate; in addition, during use, the heat inside the electrical control cabinet is exchanged with the outside world through the heat dissipation net, and during long-term use, some dust and impurities will gradually adhere to the heat dissipation net, thereby affecting the air permeability of the heat dissipation net, and ultimately affecting the heat dissipation effect of the electrical control cabinet. Utility Model Content

[0005] The purpose of the present utility model is to provide an electrical control cabinet for mines to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electrical control cabinet for mines, comprising a cabinet body, a mounting mechanism provided on the cabinet body, the mounting mechanism comprising a fixed frame, two fixed frames fixedly connected to the interior of the cabinet body, a movable plate slidably connected to the fixed frame, a mounting block fixedly connected to the cabinet body, a motor provided in the mounting block, two screw rods rotatably connected to the interior of the side wall of the cabinet body, one of the screw rods being provided on the transmission end of the motor, a pulley being respectively installed on the two screw rods, a belt being wound between the two pulleys, the two screw rods being rotatably connected to the interior of the two fixed frames, and the two screw rods being threadedly connected to the interior of the two movable plates, and a scraping mechanism being provided on the cabinet body.

[0007] As a preferred embodiment, two bases are fixedly connected to the bottom of the cabinet body, and the overall shape of the base is L-shaped.

[0008] As a preferred embodiment, a heat dissipation net is provided on the cabinet body, and the overall shape of the heat dissipation net is rectangular.

[0009] As a preferred embodiment, two guide rods are fixedly connected to the inside of the cabinet body, and the moving plate is slidably connected between the two guide rods.

[0010] As a preferred embodiment, the scraping mechanism includes a vertical frame. A vertical frame is fixedly connected to each side of the cabinet body where the heat dissipation net is located. A slider is slidably connected to the vertical frame. An installation frame is provided on one side of the two vertical frames. A group of two limiting rods are slidably connected to both ends of the installation frame respectively. The two groups of limiting rods are fixedly connected to the two sliders respectively, and the cross-section of the slider is T-shaped.

[0011] As a preferred embodiment, a spring is wound around the limiting rod. One end of the spring is fixedly connected to the limiting rod, and the other end is fixedly connected to the inside of the installation frame.

[0012] As a preferred embodiment, a cleaning scraping block is installed on the installation frame. One end of the cleaning scraping block is wedge-shaped. A handle is fixedly connected to one side of the installation frame, and the overall shape of the handle is "凵"-shaped.

[0013] As a preferred embodiment, a switch door is installed on the side of the cabinet body背离安装块 (it seems there is a mistake here, maybe "opposite to the mounting block"), and the switch door is rectangular.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] In the present utility model, by setting the cabinet body, fixed frame, moving plate, mounting block, motor, screw rod, pulley, belt and switch door, in actual operation, when it is necessary to repair and replace the electronic components inside the cabinet body, the switch door can be opened first. Then, the motor is powered on, and the motor rotates to drive the corresponding screw rod to rotate. As the above screw rod rotates, the pulley on it will also rotate, and then through the transmission of the belt, the other pulley is driven to rotate simultaneously, and then the other screw rod is also driven to rotate. Then, under the drive of the two screw rods, the corresponding moving plate will gradually move out of the inside of the cabinet body from the corresponding fixed frame, and thus the electronic components placed on the moving plate will also be moved out of the inside of the cabinet body, so that when repairing and replacing the electronic components, the corresponding operation space is enlarged, making the operation more convenient;

[0016] The utility model provides a heat dissipation net, a vertical frame, a placement frame, a handle, a cleaning scraper, a slider, a limit rod and a spring. After a long period of use, it is inevitable that a lot of dust will adhere to the heat dissipation net. The user can hold the handle and press it, and the handle will then apply pressure to the placement frame, causing the placement frame to be displaced relative to the limit rod, while driving the cleaning scraper installed thereon to move together, and the spring is compressed at the same time until the cleaning scraper contacts the heat dissipation net. Then, the handle can be pulled, thereby driving the placement frame and the cleaning scraper thereon to slide on the vertical frame through the slider. As the cleaning scraper scrapes the surface of the heat dissipation net, it is convenient to scrape and clean the dust and impurities adhered to the surface of the heat dissipation net at any time, avoiding affecting the air permeability of the heat dissipation net, and ensuring the heat dissipation effect of the cabinet.

[0030] Specifically, such as Figure 1 、 Figure 2 and Figure 3 As shown, two bases 2 are fixedly connected to the bottom of the cabinet 1, and the base 2 is L-shaped as a whole. The base 2 is used to facilitate the fixed placement of the cabinet 1; a heat dissipation net 3 is provided on the cabinet 1, and the heat dissipation net 3 is rectangular as a whole. The heat dissipation net 3 is used to facilitate the dissipation of heat inside the cabinet 1.

[0031] Specifically, such as Figure 5 As shown, two guide rods 408 are fixedly connected inside the cabinet 1, and the movable plate 402 is slidably connected to the two guide rods 408. The guide rods 408 serve as a limiting guide for facilitating the sliding of the movable plate 402.
