In the field of power infrastructure, power cabinets are common equipment. Power cabinets are a common power infrastructure and are usually placed outdoors for storage, control and protection of electrical equipment. Since there are usually heat dissipation holes on the power cabinet to dissipate heat inside the power cabinet, dust enters the power cabinet through the heat dissipation holes.

[0003] The Chinese patent "An Electric Power Dust-proof Power Cabinet" authorization announcement number "CN219874515U" can reduce the dust from the outside from entering the power cabinet through the dust-proof nets on both sides, and clean the two dust-proof nets by reciprocating up and down two brushes. The cleaned dust is drained through the drainage plate and falls into the two receiving boxes. After cleaning, the two receiving boxes are taken out by pulling the two pull rods outward, and the cleaned dust can be taken out. The utility model has a simple structure and is easy to use. The electric power dust-proof power cabinet can automatically clean and remove dust from the dust-proof nets of the heat dissipation holes of the power cabinet, saving time and effort, and increasing the dust-proof effect of the power cabinet.

[0004] Although the dust screen can be cleaned, the dust accumulated on the dust screen will be lifted up again and adhere to the electronic components inside the power cabinet due to the movement of the brush when cleaning, thereby reducing the dust prevention effect of the power cabinet.

[0005] Therefore, an electric dustproof power cabinet is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] 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.

[0026] When implementing: Figure 1-6 As shown, an electric dustproof power cabinet comprises: a power cabinet body 1, a mounting frame 2 is fixedly connected to one side of the power cabinet body 1, a dustproof net 3 is fixedly connected to the inner wall of the mounting frame 2, and a cleaning mechanism 4 is arranged inside the mounting frame 2; wherein, the cleaning mechanism 4 comprises a motor 401, a protective frame 402 is fixedly connected to one side of the mounting frame 2, a reciprocating screw rod 403 is rotatably connected to the inner wall of the protective frame 402, the bottom end of the reciprocating screw rod 403 passes through the protective frame 402 and is fixedly connected to the output shaft of the motor 401, a cleaning brush 404 is slidably connected to the inner wall of the mounting frame 2, one side of the cleaning brush 404 passes through the mounting frame 2 and is slidably connected to the surface of the reciprocating screw rod 403, a rear end of the cleaning brush 404 is fixedly connected to a dust collecting box 405, a front end of the dust collecting box 405 is fixedly connected to dust suction pipes 406 distributed in equal rows, and a cleaning component 407 is arranged on one side of the mounting frame 2.

[0027] The mounting frame 2 corresponds to the position of the heat dissipation holes of the power cabinet body 1. When the dust screen 3 needs to be cleaned, the motor 401 is started. The motor 401 is arranged inside the protective box to protect the motor 401. The output shaft of the motor 401 drives the reciprocating screw 403 to rotate. The reciprocating screw is in the form of two thread grooves with the same pitch and opposite rotation directions. The two ends are connected by a transition curve. Through the rotation of the reciprocating screw, the side of the spiral groove pushes the slider placed in the spiral groove to make axial reciprocating motion. When the reciprocating screw 403 rotates, it will drive the cleaning brush 404 to move up and down to clean the dust screen 3. While cleaning, the cleaning mechanism 4 runs.

[0028] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the cleaning assembly 407 includes two gears 4071, and the two gears 4071 are meshed and connected. The inner wall of one gear 4071 is fixedly connected to the output shaft of the motor 401, and the top of the other gear 4071 is fixedly connected to a threaded sleeve 4072. A cylinder 4073 is fixedly connected to one side of the mounting frame 2. The top of the threaded sleeve 4072 penetrates into the interior of the cylinder 4073. A piston plate 4075 is slidably connected to the interior of the cylinder 4073. The bottom end of the piston plate 4075 is rotatably connected to a threaded rod 4074. The surface of the threaded rod 4074 is threadedly connected to the inner wall of the threaded sleeve 4072. An air intake pipe 4076 is arranged between the dust box 405 and the cylinder 4073, and a first one-way valve 4077 is arranged on the surface of the air intake pipe 4076.

[0029] When the output shaft of the motor 401 drives the reciprocating screw rod 403 to rotate clockwise, the cleaning brush 404 is driven downward to clean the dust screen 3 under the action of the reciprocating screw rod 403. At the same time, the output shaft of the motor 401 synchronously drives the gear 4071 to rotate. Since the two gears 4071 are meshed and connected, the other gear 4071 drives the threaded sleeve 4072 to rotate counterclockwise, so that the bottom end of the threaded rod 4074 moves into the threaded sleeve 4072. At this time, the top end of the threaded rod 4074 drives the piston plate 4075 to move downward. At this time, the first one-way valve 4074 is opened. Under the action of 77 and the air inlet pipe 4076, the external gas will enter the cylinder 4073. The other end of the air inlet pipe 4076 passes through the mounting frame 2 and is connected to the top of the dust box 405. The dust suction pipe 406 is connected to the dust box 405. When the air inlet pipe 4076 sucks the external gas, the gas will be sucked in through the dust suction pipe 406 and pass through the dust box 405 and the air inlet pipe 4076 into the cylinder 4073. Therefore, when the cleaning brush 404 moves downward to clean the dustproof net 3, the dust raised again will be sucked into the dust box 405 by the dust suction pipe 406.

[0030] like Figure 3 , Figure 4 and Figure 6 As shown, the top of the cylinder 4073 is fixedly connected with an air outlet pipe 40710, the top and bottom of the dust box 405 are fixedly connected with connecting pipes 4078, the air outlet pipe 40710 is connected with the connecting pipe 4078, the surface of the connecting pipe 4078 is fixedly connected with exhaust pipes 4079 distributed in equal rows, and the surface of the air outlet pipe 40710 is provided with a second one-way valve 40711. The number ratio of the connecting pipe 4078 to the air outlet pipe 40710 is two: one.

[0031] When the output shaft of the motor 401 drives the reciprocating screw 403 to rotate counterclockwise, the cleaning brush 404 is driven to move upward to clean the dust net 3 under the action of the reciprocating screw 403, the threaded sleeve 4072 rotates clockwise, and the threaded rod 4074 pushes the piston plate 4075 to move upward to squeeze the gas in the cylinder 4073. At this time, under the action of the air outlet pipe 40710 and the second one-way valve 40711, the gas in the cylinder 4073 will be discharged through the air outlet pipe 40710, and at the same time enter the two connecting pipes 4078, and be discharged through the exhaust pipe 4079. At this time, when the cleaning brush 404 moves upward to clean the dust net 3, the re-raised dust will be blown out under the action of the exhaust pipe 4079 to prevent dust from entering the power cabinet body 1.

[0032] like Figure 5 As shown, the inner wall of the dust box 405 is fixedly connected with a filter 40712, and the angle between the filter 40712 and the horizontal plane is 45 degrees. The dust suction pipe 406 sucks the external air and dust into the dust box 405 at the same time, and after being filtered by the filter 40712, the dust is retained in the dust box 405, and the air enters the cylinder 4073 through the air inlet pipe 4076.

[0033] like Figure 4 As shown, the bottom end of the piston plate 4075 is fixedly connected to the limit rod 408, and the bottom end of the limit rod 408 penetrates the cylinder 4073. The surface of the limit rod 408 is slidably connected to the inner wall of the cylinder 4073, and when the piston plate 4075 moves up and down, it drives the limit rod 408 to move up and down synchronously.

[0034] like Figure 5 As shown, the other end of the dust suction pipe 406 is trumpet-shaped, and the cleaning brush 404 is arranged between the two dust suction pipes 406 on the vertical plane. When the cleaning brush 404 moves downward for cleaning, the upper and lower dust suction pipes 406 of the cleaning brush 404 simultaneously absorb the raised dust.

[0035] like Figure 5 and Figure 6 As shown, the bottom ends of the air inlet pipe 4076 and the air outlet pipe 40710 are both configured as bellows. The portions of the air inlet pipe 4076 and the air outlet pipe 40710 configured as bellows are located inside the mounting frame 2.

[0036] When the utility model is in use, when the dustproof net 3 needs to be cleaned, the starting motor 401 drives the reciprocating screw rod 403 to rotate clockwise. At this time, the cleaning brush 404 moves downward to clean the dustproof net 3. Under the action of the two gears 4071, the threaded sleeve 4072 rotates counterclockwise and makes the threaded rod 4074 drive the piston plate 4075 to move downward. At this time, the dust suction pipe 406 will suck in the external gas. Therefore, the dust and air raised by the cleaning brush 404 during cleaning will be sucked into the dust collecting box 405 through the dust suction pipe 406 at the same time, and after being filtered by the filter net 40712, the dust will be retained in the dust collecting box 405, and the air will enter the cylinder 4073 through the air inlet pipe 4076.

[0037] When the cleaning brush 404 moves upward to clean the dustproof net 3, the motor 401 drives the reciprocating screw rod 403 to rotate counterclockwise. Therefore, the threaded sleeve 4072 rotates clockwise and causes the threaded rod 4074 to push the piston plate 4075 to move upward to squeeze the gas in the cylinder 4073. At this time, the gas in the cylinder 4073 will enter the two connecting pipes 4078 at the same time through the outlet pipe 40710, and be discharged through the exhaust pipe 4079, blowing out the dust raised again during cleaning to prevent dust from entering the power cabinet body 1.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
