[0029] 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.

[0030] Reference Figure 2 - Figure 3 The utility model provides an embodiment: an outdoor lightning protection high-voltage switch cabinet, including a control cabinet 1, a lightning rod 2 is fixedly connected to the upper surface of the control cabinet 1, a wire box 3 is fixedly connected to the upper surface of the control cabinet 1, a lead 4 is arranged inside the wire box 3, one end of the lead 4 is fixedly connected to the lightning rod 2, and the other end of the lead 4 is fixedly connected to a grounding grid 5, a limiting groove 6 is provided inside the control cabinet 1, a concave hole 7 is provided inside the control cabinet 1, a mounting plate 8 is arranged inside the control cabinet 1, a limiting assembly is arranged on the side wall of the mounting plate 8, a fixing frame 10 is fixedly connected to the side wall of the mounting plate 8, and a fixing frame 10 is fixedly connected inside the fixing frame 10 A positioning block 11 is connected, a sliding block 12 is slidably connected inside the fixed frame 10, a spring 13 is arranged inside the fixed frame 10, one end of the spring 13 is fixedly connected inside the positioning block 11, and the other end of the spring 13 is fixedly connected to the side wall of the sliding block 12, a push plate 14 is fixedly connected to the side wall of the sliding block 12, and the side wall of the push plate 14 is slidably connected inside the fixed frame 10, a clamping block 15 is fixedly connected to the side wall of the sliding block 12, and the side wall of the clamping block 15 is slidably connected inside the recessed hole 7, and the limiting assembly includes a slider 9, a side wall of the slider 9 is fixedly connected to the side wall of the mounting plate 8, and a side wall of the slider 9 is slidably connected inside the limiting groove 6.

[0031] When lightning strikes, the lightning rod 2 becomes the first target of lightning due to its height and conductivity, and then guides the lightning to the grounding grid 5 through the lead 4. The grounding grid 5 will quickly disperse the lightning energy and release it to the ground, thereby greatly reducing the damage to the equipment. During the use of the equipment, the electrical components may fail or be damaged, and they need to be regularly inspected and maintained. When it is necessary to inspect the electrical components on the mounting plate 8, the operator only needs to push the push plates 14 on both sides inward at the same time. This action makes the block 15 slide out from the inside of the recessed hole 7 and slide into the inside of the fixed frame 10. At this time, the mounting plate 8 can be pulled out from the inside of the control cabinet 1, which provides convenience for the inspection work. After the inspection is completed, push the push plate 14 inward again, so that the block 15 slides into the inside of the fixed frame 10, and the spring 13 is squeezed and contracted. Then, push the mounting plate 8 back to the inside of the control cabinet 1 until it is reset. Then release the push plate 14 to make the spring 13 lose pressure and reset, and push the block 15 to re-enter the recessed hole 7 to limit the position of the mounting plate 8 to ensure that the device will not accidentally fall off or loosen during normal operation.

[0032] Reference Figure 1 , Figure 2 and Figure 3 A heat dissipation groove 16 is opened inside the control cabinet 1, a filter 17 is fixedly connected inside the control cabinet 1, and the filter 17 covers the inner side of the heat dissipation groove 16. A heat dissipation fan 18 is fixedly connected inside the control cabinet 1, a filter frame 19 is fixedly connected to the rear side wall of the control cabinet 1, and the filter frame 19 is arranged directly behind the heat dissipation fan 18. A cabinet door 20 is slidably connected inside the control cabinet 1, an observation window 21 is fixedly connected inside the cabinet door 20, and a handle 22 is fixedly connected to the side wall of the cabinet door 20.

[0033] The heat dissipation slot 16 effectively discharges the heat inside the cabinet, and the filter 17 can effectively block external dust, preventing it from entering the control cabinet 1 through the heat dissipation slot 16 and causing damage to the electrical components. When the temperature inside the control cabinet 1 is high, natural heat dissipation cannot meet the demand. At this time, the heat dissipation fan 18 is started, and the heat dissipation fan 18 can accelerate the air flow inside the control cabinet 1 by forced convection, thereby improving the heat dissipation efficiency. The filter frame 19 can also effectively block external dust, preventing it from entering the control cabinet 1 through the heat dissipation fan 18, thereby ensuring the normal operation and service life of the equipment.

[0034] Working principle: When installing the equipment, the grounding grid 5 is buried underground. When struck by lightning, the lightning rod 2 will become the first target hit by the lightning, thereby guiding the lightning to the ground through the lead 4 to the ground grid 5. The grounding grid 5 will safely release the guided lightning to the ground, disperse it and reduce the damage to the building or equipment. During the use of the equipment, when it is necessary to inspect and repair the electrical components installed on the mounting plate 8, the push plates 14 on both sides can be pushed inward at the same time to drive the card block 15 to slide out of the inside of the recessed hole 7 and slide into the inside of the fixed frame 10. At this time, the mounting plate 8 is pulled out from the inside of the control cabinet 1, and the electrical components on the mounting plate 8 are inspected. After the inspection is completed, the push plate 14 is pushed inward again to make the card block 15 slide into the inside of the fixed frame 10, and the spring 13 is squeezed and contracted, and then the mounting plate 8 is installed. Push it back to the inside of the control cabinet 1. When the mounting plate 8 is reset, release the push plate 14. The spring 13 will lose pressure and reset at this time, and push the block 15 to make it enter the inside of the recessed hole 7 again, so as to limit the position of the mounting plate 8. The electrical components will generate heat during use, and this heat will be discharged from the inside of the control cabinet 1 through the heat dissipation groove 16. During the heat dissipation process, the filter 17 will block the external dust to prevent the dust from entering the inside of the control cabinet 1 through the heat dissipation groove 16 and affecting the electrical components. When the temperature inside the control cabinet 1 is high, the heat dissipation fan 18 can be started. The heat dissipation fan 18 will blow air into the inside of the control cabinet 1, thereby speeding up the ventilation efficiency inside the control cabinet 1. The filter frame 19 will also block the external dust to prevent the heat dissipation fan 18 from blowing dust into the inside of the control cabinet 1, thereby ensuring the service life of the equipment.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
