DETAILED DESCRIPTION

[0021] 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.

[0022] Reference Figure 1-4 A constant voltage frequency converter with dustproof function includes a box body 1, a strap 101 is fixedly connected to the inner wall of the box body 1, a ventilation hole is arranged on the surface of the strap 101, and a frequency converter body 102 is clamped on the top of the strap 101, and also includes:

[0023] The top of the box body 1 is fixedly connected to the heat dissipation box 2, and the heat dissipation box 2 is connected to the box body 1. The top of the heat dissipation box 2 is fixedly connected to a servo motor 201, the output end of the servo motor 201 is fixedly connected to a rotating shaft 202, and the end of the rotating shaft 202 is fixedly connected to a fan blade 203. The top of the other side of the heat dissipation box 2 is fixedly connected to a first filter plate 204, and the heat dissipation box 2 is connected to the outside through the first filter plate 204.

[0024] A rotating column 205 is rotatably connected to the top of the first filter plate 204, and a crawler 206 is rotatably connected between the rotating column 205 and the rotating shaft 202;

[0025] A cleaning plate 207 is fixedly connected to the side wall of the rotating column 205 on the surface of the first filter plate 204, and an air outlet box 208 is fixedly connected to the side walls of both sides of the box body 1 below the strap 101;

[0026] It should be noted that: when the servo motor 201 is turned on, the servo motor 201 drives the rotating shaft 202 to rotate, and the rotating shaft 202 drives the fan blades 203 to rotate to generate wind force, blowing the cold air in the inner cavity of the heat sink 2 to the inner cavity of the box body 1, so as to dissipate the heat of the inverter body 102. Since the surface of the strap 101 that is connected to the inverter body 102 is provided with ventilation holes, the bottom of the inverter body 102 can be cooled, and the hot air is discharged through the air outlet box 208 under the strap 101, and the first filter plate 204 will filter and remove dust from the air entering the inner cavity of the heat sink 2. At the same time, the rotating shaft 202 drives the rotating column 205 to rotate by the crawler 206, and the rotation of the rotating column 205 drives the cleaning plate 207 to rotate, so as to remove the dust on the surface of the first filter plate 204, and prevent the dust from blocking the first filter plate 204 and reducing the air intake effect of the heat sink 2, thereby affecting the heat dissipation.

[0027] Reference Figure 1-4 The inner wall of the strap 101 is rotatably connected with a rotating disk 3, and both sides of the inner wall of the strap 101 are slidably connected with sliding plates 301, and the rotating disk 3 and the sliding plates 301 are meshingly connected;

[0028] Clamps 302 are slidably connected to both sides of the surface of the strap 101. The clamps 302 are used to clamp the inverter body 102, and the clamps 302 are fixedly connected to the sliding plate 301.

[0029] The side wall of the rotating disk 3 is provided with a tooth groove 303, and the side wall of the sliding plate 301 is fixedly connected with an inner tooth plate 304, and the inner tooth plate 304 is meshedly connected with the tooth groove 303 on the side wall of the rotating disk 3;

[0030] It should be noted that: when the rotating disk 3 is rotated, since the tooth grooves 303 on the side walls of the rotating disk 3 and the inner tooth plates 304 on the side walls of the sliding plate 301 are meshed, when the rotating disk 3 is rotated, the sliding plate 301 is driven to move closer to the middle of the strap 101, and at the same time, the clamping plate 302 is driven to move closer to the middle, thereby completing the clamping and fixing of the inverter body 102. Similarly, rotating the rotating disk 3 in the opposite direction can complete the disassembly of the inverter body 102, and the inverter body 102 can be taken out from the inner cavity of the box body 1 to complete maintenance.

[0031] Reference Figure 1-4 The inner wall of the air outlet box 208 is slidably connected with a second filter plate 305, and the top of the second filter plate 305 is threadedly connected with a fixing bolt 306, which can extend to the inner cavity of the air outlet box 208;

[0032] It should be noted that the second filter plate 305 can remove dust from the air exchanged between the air outlet box 208 and the outside world to prevent dust from entering the inner cavity of the box body 1 through the air outlet box 208, and by rotating the fixing bolt 306, the second filter plate 305 can be removed from the inner cavity of the air outlet box 208 to facilitate dust cleaning.

[0033] Operation method: Turn on the servo motor 201, the servo motor 201 drives the rotating shaft 202 to rotate, and the rotating shaft 202 drives the fan blades 203 to rotate to form wind force, blowing the cold air in the inner cavity of the heat sink 2 to the inner cavity of the box body 1, and dissipating the heat of the inverter body 102. Since the surface of the strap 101 that is connected to the inverter body 102 is provided with ventilation holes, the bottom of the inverter body 102 can be cooled, and the hot air is dispersed through the air outlet box 208 under the strap 101, and the first filter plate 204 will filter and remove dust from the air entering the inner cavity of the heat sink 2. At the same time, the rotating shaft 202 drives the rotating column 205 to rotate by means of the crawler 206, and the rotating column 205 drives the cleaning plate 207 to rotate, thereby removing dust on the surface of the first filter plate 204, and preventing the dust from blocking the first filter plate 204 and reducing the air intake effect of the heat dissipation box 2, thereby affecting the heat dissipation. The second filter plate 305 can remove dust from the air exchanged between the air outlet box 208 and the outside, and prevent dust from entering the inner cavity of the box body 1 through the air outlet box 208. In addition, by rotating the fixing bolt 306, the second filter plate 305 can be removed from the inner cavity of the air outlet box 208, so as to facilitate dust cleaning.

[0034] Among them, when the rotating disk 3 is rotated, since the tooth grooves 303 on the side walls of the rotating disk 3 and the inner tooth plates 304 on the side walls of the sliding plate 301 are meshed, when the rotating disk 3 is rotated, the sliding plate 301 is driven to move closer to the middle of the strap 101, and at the same time, the clamping plate 302 is driven to move closer to the middle, thereby completing the clamping and fixing of the inverter body 102. Similarly, rotating the rotating disk 3 in the opposite direction can complete the disassembly of the inverter body 102, and the inverter body 102 can be taken out from the inner cavity of the box body 1 to complete maintenance.
