Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a distribution box monitoring and protection system. Background Art

[0002] The distribution box is an electrical equipment with the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint and environmental protection.

[0003] At present, when the distribution box is used in outdoor environments, if it is in relatively hot weather, it is easy to cause a high temperature inside the distribution box due to the influence of the outdoor temperature. Therefore, heat dissipation vents and filters are usually opened for ventilation, and then a fan is installed inside the distribution box for heat dissipation.

[0004] However, the practicality of the heat dissipation device is poor when working. First, the device is used to block the dust in the air through a filter, but too much dust will accumulate in the filter holes of the filter and affect the ventilation efficiency. In addition, because the heat dissipation port is not sealed, it is easy for the inside of the distribution box to get damp, resulting in poor use effect. In view of this, we propose a distribution box monitoring and protection system. Summary of the invention

[0005] The purpose of the utility model is to provide a distribution box monitoring and protection system to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a distribution box monitoring and protection system, comprising a distribution box body, components are arranged inside the distribution box body, ventilation slots are opened on both sides of the distribution box body, filters are arranged inside the ventilation slots, and a protection structure is arranged inside the distribution box body, and the protection structure includes:

[0026] Specifically, the protective structure 3 of the technical solution of the utility model includes: a bearing 31, a rotating rod 32, a fan blade 33, a ventilation frame 34, a heat dissipation fan 35, a bevel column 36, a sleeve 37, a fixed cylinder 38, an extrusion spring 39, a sliding block 310, a support rod 311, and a cleaning brush 312.

[0027] In one embodiment of the present invention, bearings 31 are fixedly mounted on the upper and lower ends of the inner wall of the ventilation slot 5, and a rotating rod 32 is rotatably connected inside the two sets of bearings 31. The surface of the rotating rod 32 is provided with a fan blade 33. Ventilation frames 34 are fixedly mounted on both sides of the inner wall of the distribution box body 1, and a heat dissipation fan 35 is fixedly mounted on the inner wall of the ventilation frame 34. An inclined groove column 36 is fixedly mounted on the upper and lower surfaces of the rotating rod 32, and a sleeve 37 is rotatably connected on the surface of the inclined groove column 36. A fixed cylinder 38 is fixedly mounted on the side wall of the sleeve 37, and one end of an extrusion spring 39 is fixedly mounted on the inner wall of the fixed cylinder 38, and a sliding block 310 is fixedly mounted on the other end of the extrusion spring 39. One end of a support rod 311 is fixedly mounted on the side wall of the sliding block 310, and a cleaning brush 312 is fixedly mounted on the side wall of the support rod 311. By setting the protective structure 3, it is convenient to clean the dust on the surface of the filter 6. Natural ventilation is performed through the ventilation slot 5, and the filter 6 is used to filter dust in the air. When the monitor 7 detects that the temperature of the distribution box body 1 is high, the control unit inside the monitor 7 can start the heat dissipation fan 35 for heat dissipation. The operation of the heat dissipation fan 35 will drive the output shaft and the fan blades on its surface to rotate. At this time, the wind force will drive the fan blades 33 to rotate. The rotation of the fan blades 33 drives the internal rotating rod 32 to rotate inside the bearing 31. The rotation of the rotating rod 32 drives the inclined groove column 36 on its surface to rotate, and then drives the sleeve 37 to move up and down. The up and down movement of the sleeve 37 drives the fixed cylinder 38 and the cleaning brush 312 on its side wall to clean the upper and lower sides of the filter 6, thereby preventing dust from accumulating in the filter holes of the filter 6 and affecting the ventilation efficiency. A sealing structure 4 is arranged inside the ventilation slot 5.

[0028] Please continue reading Figure 1-Figure 6The sealing structure 4 includes a slide groove 41 provided at the upper and lower ends of the inner wall of the ventilation groove 5, and a positioning block 42 is slidably connected to the inner wall of the slide groove 41. Two groups of positioning blocks 42 are respectively fixedly connected to the upper and lower ends of the filter screen 6. The side wall of the filter screen 6 is fixedly connected to two groups of fixing rods 43, and the side wall of the fixing rod 43 is fixedly installed with a sealing plate 44. The lower end of one of the two groups of fixed cylinders 38 is hinged to one end of a connecting rod 45, and the other end of the connecting rod 45 is hinged to the side wall of the filter screen 6. By setting up the sealing structure 4, it is convenient to seal the ventilation groove 5. When the heat dissipation fan 35 rotates forward, it will drive the fixed cylinder 38 to move, and the movement of the fixed cylinder 38 drives it The connecting rod 45 at the lower end moves, and the movement of the connecting rod 45 drives the filter 6 hinged thereto to move on the surface of the slide groove 41. The movement of the filter 6 drives the fixing rod 43 and the sealing plate 44 of its side wall to move outward away from the ventilation groove 5, and when the subsequent heat dissipation fan 35 rotates in the opposite direction, the sealing plate 44 can be returned to the center by moving upward through the sleeve 37, thereby preventing the inside of the distribution box body 1 from getting damp. The moving trajectory of the filter 6 is adapted to the moving trajectory of the support rod 311, the ventilation groove 5 and the sealing plate 44 are adapted, the positions of the fan blades 33 and the heat dissipation fan 35 are adapted, the cleaning brush 312 is in contact with the surface of the filter 6, and a monitor 7 is fixedly installed on the inner wall of the distribution box body 1.

[0029] The distribution box body 1 is naturally ventilated through the ventilation slots 5, and the filter 6 is used to filter dust in the air. When the monitor 7 detects that the temperature of the distribution box body 1 is high, the control unit inside the monitor 7 can start the heat dissipation fan 35 to dissipate heat. The operation of the heat dissipation fan 35 will drive the output shaft and the fan blades on its surface to rotate. At this time, the wind will drive the fan blades 33 to rotate. The rotation of the fan blades 33 drives the rotating rod 32 inside the bearing 31 to rotate. The rotation of the rotating rod 32 drives the inclined groove column 36 on its surface to rotate, thereby driving the sleeve 37 to move up and down. The up and down movement of the sleeve 37 drives the fixed cylinder 38 and the cleaning brush 312 on its side wall to move up and down. The upper and lower sides of the filter 6 are cleaned, and the movement of the fixed cylinder 38 drives the connecting rod 45 at its lower end to move. The movement of the connecting rod 45 drives the filter 6 hinged thereto to move on the surface of the slide groove 41. The movement of the filter 6 drives the fixing rod 43 and the sealing plate 44 of its side wall to move outward and leave the ventilation groove 5. At this time, the cleaning brush 312 is supported by the support rod 311 of its side wall and the elastic force of the extrusion spring 39, so that the cleaning brush 312 is always in close contact with the surface of the filter 6 for cleaning, and when the heat dissipation fan 35 can be rotated in the opposite direction later, the sealing plate 44 can be moved upward by the sleeve 37 to return to the center, thereby protecting the inside of the distribution box body 1.
