Description

A current protection measurement and control device

Technical Field

The utility model relates to the technical field of microcomputer protection measurement and control devices, in particular to a current protection measurement and control device.

Background Art

The microcomputer protection and measurement and control device integrates control, protection, measurement, signal alarm, switch quantity acquisition, and communication functions. The main microcomputer protection and measurement and control devices are mainly divided into voltage protection and measurement and control devices, current protection and measurement and control devices, motor protection and measurement and control devices, low-voltage transformer microcomputer protection and measurement and control devices, etc.

A current protection measurement and control device with a publication number of CN210007368U has been retrieved. The current protection measurement and control device includes a panel, a mounting frame and a back plate. The mounting frame is fixed to the back of the panel. The back of the mounting frame is detachably fixed with a back plate. A heat dissipation component is arranged inside the mounting frame to dissipate heat for electronic equipment inside the mounting frame. A dustproof component is arranged inside the mounting frame. The utility model has the advantages that, firstly, by arranging a heat dissipation component, the heat generated by the protective device inside the mounting frame when working can be brought out of the mounting frame in time, thereby preventing a large amount of heat from accumulating inside the mounting frame and causing damage to the protective device; secondly, by arranging a dustproof component, the connecting part between the mounting frame and the outside world can be dustproofed to prevent impurities in the outside air from entering and accumulating inside the mounting frame, which can provide dustproof protection for the protective device and also reduce the workload of the staff.

In view of the above-mentioned related technologies, the inventor believes that after the device is used for a long time, a large amount of dust and foreign matter will adhere to the filter screen. If it is not cleaned, the heat dissipation effect will be affected. If the dust and foreign matter on the filter screen are removed directly by cleaning the filter screen, due to the internal closed space, it is easy for water to enter the interior when it contacts the filter screen, thereby causing water to enter the internal parts and affect the use. At this time, the filter screen needs to be disassembled and the dust and foreign matter are cleaned, which makes the cleaning of the filter screen cumbersome. To this end, we propose a current protection measurement and control device.

If the dust and foreign matter on the filter screen is removed directly by cleaning the filter screen, due to the enclosed space inside, it is easy for water to enter the interior when it comes into contact with the filter screen, thereby causing water to enter the internal components and affecting their use. At this time, the filter screen needs to be disassembled and the dust and foreign matter need to be cleaned, resulting in the problem of cumbersome filter cleaning.

When in use, the protective device is installed inside the box body 1. When the protective device is working, heat is generated, and the cooling fan 4 is started. The cooling fan 4 blows the heat gathered around the protective device out of the box body 1 through the vent 5. The filter 6 can intercept dust and other impurities. When the filter 6 needs to be cleaned after being used for a long time, the motor 10 is started. The motor 10 drives the screw 9 to rotate. Since the mounting plate 14 is threadedly connected to the screw 9, the mounting plate 14 can be driven to move up and down, and then the brush plate 17 can be driven to remove dust and other impurities attached to the surface of the filter 6.

A mounting groove 2 is provided on the surface of the box body 1 .

The brush plate 17 and the filter screen 6 are consistent in size and position;

In order to improve the cleaning effect, as shown in FIGS. 1-3 , a spring 18 is nested on the telescopic rod 16 , one end of the spring 18 is fixedly connected to the inner wall of the groove 15 , and the other end of the spring 18 is fixedly connected to the outer wall of the brush plate 17 ;

The elastic effect of the spring 18 can push the brush plate 17 to always be in contact with the surface of the filter screen 6, thereby improving the cleaning effect of the brush plate 17 on the filter screen 6.

In order to limit the mounting plate 14, as shown in Figures 1-3, a vertical plate 12 is fixedly installed on the outer wall of the box body 1, and a limiting groove 13 is provided on the vertical plate 12. A limiting block 19 is provided on the outer wall of the mounting plate 14. The limiting block 19 and the mounting plate 14 are integrated.

By setting a limit block 19 and setting it to be engaged with the limit groove 13, the mounting plate 14 can be limited to prevent it from rotating with the rotation of the screw rod 9.

When in use, the protective device is installed inside the box body 1. When the protective device is working, heat is generated, and the cooling fan 4 is started. The cooling fan 4 blows the heat gathered around the protective device out of the box body 1 through the vent 5. The setting of the filter 6 can intercept dust and other impurities. When the filter 6 needs to be cleaned after being used for a long time, the dust and other impurities attached to its surface are started, and the motor 10 is started. The motor 10 drives the screw 9 to rotate. Since the mounting plate 14 and the screw 9 are threadedly connected, the mounting plate 14 can be driven to move up and down, and then the brush plate 17 can be driven to remove the dust and other impurities attached to the surface of the filter 6 to prevent them from being attached to the surface of the filter 6 and affecting the heat dissipation effect.

The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
