DETAILED DESCRIPTION
[0017] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.
[0018] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. The present utility model is further described in detail below in conjunction with the accompanying drawings.
[0019] like Figure 1-4 As shown, the utility model proposes an outdoor frequency conversion cabinet with a dustproof and heat dissipation structure, including a frequency conversion cabinet body 1, the top wall of the frequency conversion cabinet body 1 is connected to an opening 2, the bottom wall of the frequency conversion cabinet body 1 is connected to a ventilation port 3, a bracket 4 is arranged in the opening 2, the bracket 4 is arranged in an X-shaped structure, a heat dissipation fan 5 is arranged on the bracket 4, a dustproof net 1 6 is removably arranged on the opening 2, and a dustproof net 2 7 is arranged on the ventilation port 3. The heat dissipation fan 5, in conjunction with the ventilation port 3 and the opening 2, can promote the exchange of airflow inside and outside the frequency conversion cabinet body 1 to achieve heat dissipation. At the same time, the dustproof net 1 6 and the dustproof net 2 7 can prevent external dust from entering the frequency conversion cabinet body 1 during heat dissipation and ventilation.
[0020] The bottom wall of the frequency conversion cabinet body 1 is provided with a dust cleaning member 8, and the dust cleaning member 8 includes a support plate 9, a lead screw 10, a lead screw pair 11, a slide bar 12 and a brush plate 13. The support plate 9 is provided on the bottom wall of the frequency conversion cabinet body 1, and both ends of the lead screw 10 are rotatably provided on the support plate 9, and both ends of the slide bar 12 are provided on the support plate 9. The lead screw pair 11 is threadedly connected with the lead screw 10 and is slidably sleeved on the slide bar 12. The brush plate 13 is provided on the lead screw pair 11. It is arranged in contact with the dustproof net 27, and the side wall of the support plate 9 is provided with a driving motor 14. The output end of the driving motor 14 rotates through the support plate 9 and is connected to the screw 10. Because the bottom dustproof net 27 is not convenient to clean, the driving motor 14 can be started to drive the screw 10 to rotate, and the screw pair 11 can drive the brush plate 13 to clean the dust on the outside of the dustproof net 27 to prevent dust from clogging the dustproof net 27 and affecting heat dissipation. The dustproof net 6 can be cleaned by disassembly.
[0021] The four corners of the bottom wall of the frequency converter cabinet body 1 are provided with supporting legs 15, a slide plate 16 is provided between the supporting legs 15, a roller 17 is provided on the bottom wall of the slide plate 16, and a telescopic member 18 is provided between the slide plate 16 and the frequency converter cabinet body 1. The slide plate 16 is driven downward by the telescopic member 18, and the roller 17 can prop up the frequency converter cabinet body 1 for movement.
[0022] The telescopic member 18 includes an electric telescopic rod 19 , a fixed end of which is disposed on a side wall of the frequency conversion cabinet body 1 , and a movable end of which is disposed on the slide plate 16 .
[0023] The opening 2 and the ventilation port 3 are both fixed to the frequency conversion cabinet body 1 by bolts.
[0024] During specific use, the heat dissipation fan 5, in conjunction with the ventilation port 3 and the opening 2, can promote the exchange of airflow inside and outside the frequency converter cabinet body 1 to achieve heat dissipation. At the same time, the dustproof net 1 6 and the dustproof net 2 7 can prevent external dust from entering the frequency converter cabinet body 1 during heat dissipation and ventilation. Since the bottom dustproof net 2 7 is not easy to clean, the drive motor 14 can be started to drive the screw 10 to rotate, and the screw pair 11 can drive the brush plate 13 to clean the dust on the outside of the dustproof net 2 7 to prevent dust from clogging the dustproof net 2 7 and affecting heat dissipation. The dustproof net 1 6 can be disassembled for cleaning.
[0025] The slide plate 16 can be driven downward by the electric telescopic rod 19, and the roller 17 can prop up the frequency conversion cabinet body 1 to move it.
[0026] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
