During the cooling process, in most cases, the air circulation in the cabinet is enhanced to achieve the cooling effect. However, due to the large amount of dust in the mining environment, the filter is easily blocked by dust, and the traditional filter is connected to the installation cabinet in an integrated manner. Dust blocking the filter will lead to poor internal heat dissipation and cause high temperature, which is easy to damage the internal components and cause economic losses. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides the following technical solutions:

[0025] Embodiment 1

[0026] See also Figure 1-2 and Figure 4-5 An electrical instrument installation cabinet includes a cabinet body 1, a filter replacement mechanism 2 is arranged at the rear end of the cabinet body 1, a switch mechanism 3 is arranged at the left end of the cabinet body 1, a switch door 4 is hinged at the front end of the cabinet body 1 through a hinge, and a support leg 5 is fixedly connected to the lower end of the cabinet body 1.

[0027] The filter replacement mechanism 2 includes a ventilation hole 201, which is opened at the rear end of the cabinet 1. The inner wall of the ventilation hole 201 is fixedly connected to a ventilation frame 202, the inner wall of the ventilation frame 202 is fixedly connected to a fan 203, the inner wall of the ventilation frame 202 is fixedly connected to a fixed block 204, the rear end of the fixed block 204 is fixedly connected to a limit rod 205, the outer wall of the limit rod 205 is movably connected to a filter screen 206, the upper end of the ventilation frame 202 is fixedly connected to a motor 207, the output shaft of the motor 207 is fixedly connected to a rotating rod 208, the outer wall of the rotating rod 208 is fixedly connected to a cam 209, and the ventilation frame 202 is fixedly connected to the inner wall of the ventilation frame 202. By using the motor 207, cam 209, spring 211, L-shaped lever 214, limit groove 215, limit rod 205 and other parts in combination, the cam 209 can continuously knock on the filter 206 during actual use to prevent the filter 206 from being blocked and affecting the heat dissipation effect. Secondly, the rotation of the L-shaped lever 214 can make the limit rod 205 disengage from the limit groove 215, so as to facilitate the replacement of the filter 206, thereby improving the heat dissipation effect and preventing the filter 206 from being blocked, resulting in poor heat dissipation and forming high temperature, which may cause damage to internal components and cause economic losses.

[0028] Furthermore, a fixing hole 210 is opened at the upper end of the ventilation frame 202, and a spring 211 is fixedly connected to the front end of the inner wall of the fixing hole 210. By using the fixing hole 210 in combination with the spring 211, during actual use, the dust shaken off the filter 206 can fall through the fixing hole 210, and the use of the spring 211 can facilitate the subsequent installation and disassembly of the filter 206.

[0029] Furthermore, a fixing rod 212 is fixedly connected to the front end of the inner wall of the fixing hole 210, and a spring 211 is movably connected to the outer wall of the fixing rod 212. By using the fixing rod 212 in combination with the spring 211, the fixing rod 212 controls the deformation angle of the spring 211. Since the spring 211 is on the outer wall of the fixing rod 212, the spring 211 can only be deformed in the left and right directions.

[0030] Furthermore, the outer wall of the fixed rod 212 is movably connected to a connecting block 213, and the upper end of the connecting block 213 is fixedly connected to an L-shaped lever 214. By using the connecting block 213 in combination with the L-shaped lever 214, during use, by moving the L-shaped lever 214, the connecting block 213 connected thereto can not only compress the spring 211, but also rotate the connecting block 213, thereby facilitating the subsequent installation of the filter 206.

[0031] Furthermore, a limiting groove 215 is provided at the front end of the connecting block 213, and the outer wall of the limiting rod 205 is matched with the inner wall of the limiting groove 215. By using the limiting rod 205 in combination with the limiting groove 215, when the limiting rod 205 is in the limiting groove 215, the filter 206 is installed; when the limiting rod 205 is out of the limiting groove 215, the filter 206 can be replaced.

[0032] Embodiment 2

[0033] Combination Figure 1-5 On the basis of the first embodiment, the switch mechanism 3 further comprises a through hole 301, the through hole 301 is provided at the left end of the cabinet 1, the lower end of the inner wall of the through hole 301 is fixedly connected with an air outlet frame 302, the right end of the air outlet frame 302 is provided with a circular hole 303, the inner wall of the circular hole 303 is fixedly connected with a second filter screen 304, the lower end of the inner wall of the through hole 301 is provided with a rectangular groove 305, the upper end of the inner wall of the rectangular groove 305 is movably connected with a threaded rod 306 through a bearing, and the threaded rod 306, the rectangular plate 307, the rectangular groove 305, the second filter screen 304 and other parts are used in combination, so that during use, the position of the rectangular block in the rectangular groove 305 is moved by rotating the threaded rod 306, so as to facilitate the control of the switch of the air outlet frame 302.

[0034] Furthermore, a rectangular plate 307 is threadedly connected to the outer wall of the threaded rod 306, and the upper end of the threaded rod 306 passes through the lower end of the through hole 301 and is movably connected to the lower end of the through hole 301 through a bearing. By using the threaded rod 306 and the rectangular plate 307, the rectangular plate 307 can move up and down under the rotation of the threaded rod 306, so that the rectangular plate 307 can dredge the air outlet frame 302. When heat dissipation is not performed, the rectangular plate 307 can be moved upward to prevent dust from entering.

[0035] In actual operation, when the device is used, the device is first installed. When it is necessary to dissipate heat, the fan 203 can be used for heat dissipation, and the motor 207 is started to drive the cam 209 to knock the filter screen 206, so that the impurities and dust adsorbed on the filter screen 206 are knocked down and fall through the fixing hole 210. When the filter screen 206 needs to be replaced, the limit groove 215 on the connecting block 213 can be disengaged from the limit position of the limit rod 205 by rotating the L-shaped lever 214, and the filter screen 206 can be replaced. 06 is completely taken out and replaced, and then the L-shaped lever 214 is toggled to compress the spring 211, prompting the subsequent limit groove 215 to align and limit with the limit rod 205. When the rectangular plate 307 is controlled to move up or down by rotating the threaded rod 306, the air outlet frame 302 can be opened when heat dissipation is needed to make it a circulation system. When heat dissipation is not needed, the rectangular plate 307 can be moved up to make the air outlet frame 302 a closed space to prevent dust and other debris from entering.
