DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0025] The present invention provides an electrical frequency conversion power distribution cabinet, as Figures 1 to 3As shown in the figure, it includes a cabinet body 1 and a cabinet door 2 on the front side of the cabinet body 1. A heat dissipation port 3 is provided on the side of the cabinet body 1. A protective net 4 is installed on the outer side of the heat dissipation port 3 by screws. The protective net 4 is correspondingly buckled inside the heat dissipation port 3. The top and bottom of the protective net 4 are installed on the side of the cabinet body 1 by screws. At this time, the protective net 4 prevents external components from entering the cabinet body 1 through the heat dissipation port 3, and the heat inside the cabinet body 1 is discharged through the heat dissipation port 3.

[0026] Side frames 5 are provided on both inner side walls of the cabinet body 1, and the heat dissipation port 3 is correspondingly communicated with the left side frame 5. A motor 6 is provided at the top of the right side frame 5. The output end of the motor 6 is drivingly connected with a screw rod. A moving frame 7 is provided between the two side frames 5. A convex plate 8 is provided at the right end of the moving frame 7. The convex plate 8 is spirally sleeved on the surface of the screw rod. The rotating screw rod makes the moving frame 7 move up and down inside the cabinet body 1 by means of the convex plate 8. An inner pipe 9 is provided inside the moving frame 7. A corrugated pipe 10 is provided inside the inner pipe 9. An exhaust pipe 11 is provided at the left end of the corrugated pipe 10, and a one-way valve is provided inside the exhaust pipe 11. A one-way valve is also provided at the right end of the corrugated pipe 10. A thread groove corresponding to a rotating sleeve 12 is provided at the left end of the moving frame 7. The surface of the exhaust pipe 11 is spirally clamped on the left side of the moving frame 7 by means of the rotating sleeve 12, and the rotating sleeve 12 is spirally sleeved on the surface of the exhaust pipe 11. The right end of the corrugated pipe 10 is connected to an adsorption component. A cylinder is installed on one side at the top of the moving frame 7. The output end of the cylinder is connected to the adsorption component. Among them, a controller is provided inside the cabinet body 1, and the cylinder and the motor 6 are both electrically connected to the controller.

[0027] When the cylinder is started, the output end of the cylinder makes the adsorption component move left and right inside the moving frame 7, and the moving adsorption component makes the corrugated pipe 10 generate a telescopic movement inside the moving frame 7. At the same time, the motor 6 is started. The screw rod at the output end of the motor 6 rotates inside the side frame 5, and the spiral cooperation between the rotating side frame 5 and the convex plate 8 makes the moving frame 7 move up and down inside the cabinet body 1. When the adsorption component moves to the right and makes the corrugated pipe 10 stretch, the stretched corrugated pipe 10 uses the adsorption component to extract the dust and hot air inside the cabinet body 1, and the hot air carrying dust enters the corrugated pipe 10 through the one-way valve on the right side; when the adsorption component moves to the left and makes the corrugated pipe 10 contract, the contracted corrugated pipe 10 discharges the hot air carrying dust through the one-way valve inside the exhaust pipe 11. At this time, the hot air carrying dust is discharged from the cabinet body 1 through the heat dissipation port 3.

[0028] The corrugated pipe 10 that performs telescopic movement inside the moving frame 7 discharges the hot air carrying dust inside the cabinet body 1 through the heat dissipation port 3. When the corrugated pipe 10 in the telescopic state moves up and down inside the cabinet body 1, the corrugated pipe 10 uses the adsorption component to comprehensively extract the dust and hot air inside the cabinet body 1, ensuring the comprehensive heat dissipation effect of the cabinet body 1.

[0029] At Figure 2 and Figure 3In it, two vertical side plates 13 are fixed to the left side of the moving frame 7. The outer side surfaces of the side plates 13 are attached to the inner side walls of the side frames 5. The moving frame 7 that moves up and down moves on the surface of the inner side walls of the side frames 5 by means of the side plates 13. The exhaust pipe 11 is located between the two side plates 13 and corresponds to the protective net 4. The left side of the moving frame 7 is in sliding fit with the left side frame 5 by means of the side plates 13. The right side of the moving frame 7 is spirally sleeved on the surface of the screw rod by means of the convex plate 8, so as to prevent the moving frame 7 from tilting or rotating inside the cabinet body 1 and ensure the stable up and down movement of the moving frame 7 inside the cabinet body 1.

[0030] In Figures 2 to 4 it, the adsorption component includes a slide carriage 14. The slide carriage 14 vertically penetrates the moving frame 7. Chute grooves corresponding to the slide carriage 14 are provided at both the top and the bottom of the moving frame 7. Inner rods 15 are arranged inside the chute grooves. The slide carriage 14 is slidably sleeved on the surface of the inner rods 15, and the output end of a cylinder is connected to the side of the slide carriage 14. A circular plate 16 is provided at the center of the slide carriage 14. The right end of the bellows 10 is connected to the circular plate 16. The right side surface of the circular plate 16 is communicated with an adsorption frame 18 through a conduit 17. The adsorption frame 18 is arranged as a circular frame-shaped screen. The stretched bellows 10 extracts the gas inside the cabinet body 1 through the adsorption frame 18. When the output end of the cylinder causes the slide carriage 14 to move to the right, the moving slide carriage 14 slides on the surface of the inner rod 15 in the chute groove, and the moving slide carriage 14 drives the circular plate 16 to move synchronously. At this time, the circular plate 16 that moves to the right pulls the bellows 10, and the extended bellows 10 starts to pump air. At this time, the gas inside the cabinet body 1 enters the inside of the bellows 10 through the adsorption frame 18, the conduit 17 and the circular plate 16. A one-way valve is used to prevent the gas inside the bellows 10 from being discharged back into the cabinet body 1 through the adsorption frame 18. At this time, most of the dust in the gas is filtered by the adsorption frame 18, and a small amount of dust enters the inside of the bellows 10 through the one-way valve. When the output end of the cylinder causes the slide carriage 14 to move to the left, the slide carriage 14 squeezes the bellows 10 by means of the circular plate 16. The gas inside the bellows 10 is discharged through the one-way valve inside the exhaust pipe 11. The bellows 10 discharges the hot air and dust through the exhaust pipe 11 and the protective net 4. While ensuring the heat dissipation of the cabinet body 1, the adsorption frame 18 and the protective net 4 can also be used to adsorb the dust inside the cabinet body 1.

[0031] In Figure Figures 2 to 4Among them, the adsorption component further includes two opposite clamping frames 19 which are arranged vertically. An arc-shaped plate is provided in the middle of the sliding frame 14. Both ends of the arc-shaped plate are provided with side edges corresponding to the clamping frames 19. A plug rod 20 penetrating through the side plate is fixed on the outer side of the clamping frame 19. A baffle 21 is fixed at the outer end of the plug rod 20. And a spring 22 is sleeved on the surface of the plug rod 20. One end of the spring 22 is connected to the side edge, and the other end of the spring 22 is connected to the baffle 21. The elastic force of the spring 22 makes the concave surface of the clamping frame 19 squeeze the adsorption frame 18. Push the two clamping frames 19 to separate from each other. The upper clamping frame 19 moves upward, and the lower clamping frame 19 moves downward. The moving clamping frame 19 makes the baffle 21 move away from the side plate by using the plug rod 20. The moving baffle 21 cooperates to pull the spring 22 on the surface of the plug rod 20 until the outer side surface of the clamping frame 19 fits with the inner side surface of the side plate. Place the adsorption frame 18 correspondingly between the two clamping frames 19. Slowly release the pulling force applied to the clamping frame 19. The elastic force of the spring 22 makes the clamping frame 19 approach the adsorption frame 18 until the concave surface of the clamping frame 19 fits with the circumferential outer side surface of the adsorption frame 18. Under the limitation of the elastic force of the spring 22, the two opposite clamping frames 19 cooperate to clamp the adsorption frame 18, completing the limitation of the adsorption frame 18.

[0032] In Figure 4 and Figure 5 Among them, movable grooves are provided at both the top and the bottom of the sliding frame 14. Protrusions are provided at both the top and the bottom of the circular plate 16. Inner grooves are provided inside the protrusions. Plug frames 23 are provided inside the inner grooves. Elastic sheets are provided inside the inner grooves. The elastic force of the elastic sheets makes the plug frames 23 penetrate through the protrusions. Vertical grooves 24 are provided at both the top and the bottom of the arc-shaped plate. The plug frames 23 are correspondingly inserted into the vertical grooves 24, and the vertical grooves 24 communicate with the movable grooves. The corrugated pipe 10 is correspondingly inserted into the inner pipe 9. A rotating sleeve 12 is spirally sleeved on the surface of the exhaust pipe 11 on the left side of the corrugated pipe 10. Until the rotating sleeve 12 corresponds to the thread groove on the left side of the moving frame 7, rotate the rotating sleeve 12. The rotating rotating sleeve 12 makes the exhaust pipe 11 be correspondingly buckled inside the thread groove of the moving frame 7, completing the limitation of the exhaust pipe 11. The circular plate 16 at the right side end of the corrugated pipe 10 is inside the arc-shaped plate of the moving sliding frame 14. At this time, the elastic force of the elastic sheet makes the outer end of the plug frame 23 extend out of the protrusion until the outer end of the plug frame 23 is correspondingly inserted into the vertical groove 24. At this time, the moving sliding frame 14 drives the circular plate 16 to move synchronously by using the plug frame 23. The moving circular plate 16 and the rotating sleeve 12 cooperate to stretch or contract the corrugated pipe 10.

[0033] In Figures 4 to 6In it, a rotating plate 25 is inserted into the movable slot. The front end of the rotating plate 25 is hinged to the baffle 21. Convex rods 26 are fixed on both side surfaces of the rear end of the rotating plate 25. Limit slots 27 corresponding to the convex rods 26 are arranged on both inner side walls of the movable slot. A sliding rod is embedded in the inner part of the rotating plate 25. A pressing rod 28 is arranged in the inner part of the rotating plate 25. The inner end of the pressing rod 28 is inserted into the vertical slot 24. The outer end of the pressing rod 28 is hinged to a connecting frame 29, and the connecting frame 29 is slidably sleeved on the surface of the sliding rod. When pulling the two clamping frames 19 away from each other, the moving clamping frame 19 uses the inserting rod 20 to make the baffle 21 drive the front end of the rotating plate 25 to move. At this time, the front end of the top rotating plate 25 moves upward, and the front end of the bottom rotating plate 25 moves downward. Since the rear end of the rotating plate 25 is slidably clamped in the limit slot 27 by the convex rod 26, the baffle 21 makes the rotating plate 25 rotate in the movable slot. The rotating rotating plate 25 slides in the limit slot 27 by the convex rod 26. At this time, the rotating rotating plate 25 uses the sliding rod and the connecting frame 29 to pull the pressing rod 28 away from the inserting frame 23. During the process of the two clamping frames 19 cooperating to clamp the adsorption frame 18, the elastic force of the elastic sheet at this time makes the outer end of the inserting frame 23 inserted into the vertical slot 24, which is convenient for the sliding frame 14 to drive the circular plate 16 and the adsorption frame 18 to move synchronously.

[0034] Rotate the rotating sleeve 12 in the reverse direction. The rotating rotating sleeve 12 moves out of the screw groove. At this time, pull the adsorption frame 18 to move between the two clamping frames 19 until the adsorption frame 18 is separated from the clamping frames 19. The elastic force of the spring 22 makes the baffle 21 close to the side plate. The moving baffle 21 pulls the front end of the rotating plate 25 to move. At this time, the front end of the top rotating plate 25 moves downward, and the front end of the bottom rotating plate 25 moves upward. The rotating rotating plate 25 uses the sliding rod and the connecting frame 29 to push the pressing rod 28 close to the inserting frame 23 until the inner end of the pressing rod 28 presses the inserting frame 23. The pressed inserting frame 23 cooperates with the elastic sheet in the pressurizing inner groove. At this time, the outer end of the inserting frame 23 gradually moves out of the vertical slot 24, completing the separation of the circular plate 16 and the sliding frame 14. At this time, the corrugated pipe 10 and the adsorption frame 18 can be taken out of the moving frame 7. At this time, the corrugated pipe 10 and the adsorption frame 18 move out of the cabinet body 1 from the heat dissipation port 3, which is convenient for comprehensively cleaning the corrugated pipe 10 and the adsorption frame 18. Then reinstall the cleaned corrugated pipe 10 and the adsorption frame 18 in the moving frame 7 to ensure the continuous dust cleaning and heat dissipation effect of the cabinet body 1.

[0035] The working principle of the present invention:

[0036] Refer to Figures 1 to 6As shown, push the two clamping frames 19 to separate from each other. The upper clamping frame 19 moves upward, and the lower clamping frame 19 moves downward. The moving clamping frame 19 uses the insertion rod 20 to move the baffle 21 away from the side plate. The moving baffle 21 cooperates with the spring 22 on the surface of the insertion rod 20 until the outer side surface of the clamping frame 19 fits against the inner side surface of the side plate. Place the adsorption frame 18 correspondingly between the two clamping frames 19, and slowly release the pulling force applied to the clamping frame 19. The elastic force of the spring 22 causes the clamping frame 19 to approach the adsorption frame 18 until the concave surface of the clamping frame 19 fits against the circumferential outer side surface of the adsorption frame 18. Under the limitation of the elastic force of the spring 22, the two opposite clamping frames 19 cooperate to clamp the adsorption frame 18, completing the limitation of the adsorption frame 18.

[0037] The bellows 10 is correspondingly inserted inside the inner tube 9. A rotating sleeve 12 is spirally sleeved on the surface of the exhaust pipe 11 on the left side of the bellows 10. When the rotating sleeve 12 corresponds to the screw groove on the left side of the moving frame 7, rotate the rotating sleeve 12. The rotating rotating sleeve 12 causes the exhaust pipe 11 to be correspondingly buckled inside the screw groove of the moving frame 7, completing the limitation of the exhaust pipe 11. The circular plate 16 at the right end of the bellows 10 moves inside the arc-shaped plate of the sliding frame 14. At this time, the elastic force of the elastic piece causes the outer end of the insertion frame 23 to extend out the convex block until the outer end of the insertion frame 23 is correspondingly inserted inside the vertical groove 24. At this time, the moving sliding frame 14 drives the circular plate 16 to move synchronously by using the insertion frame 23. The moving circular plate 16 and the rotating sleeve 12 cooperate to stretch or contract the bellows 10.

[0038] Start the cylinder. The output end of the cylinder causes the adsorption component to move left and right inside the moving frame 7. The moving adsorption component causes the bellows 10 to produce a telescopic movement inside the moving frame 7. At the same time, start the motor 6. The screw rod at the output end of the motor 6 rotates inside the side frame 5. The spiral cooperation between the rotating side frame 5 and the convex plate 8 causes the moving frame 7 to move up and down inside the cabinet body 1. When the adsorption component moves to the right and causes the bellows 10 to stretch, the stretched bellows 10 uses the adsorption component to extract the dust and hot air inside the cabinet body 1. The hot air carrying dust enters the bellows 10 through the one-way valve on the right side; when the adsorption component moves to the left and causes the bellows 10 to contract, the contracted bellows 10 discharges the hot air carrying dust through the one-way valve inside the exhaust pipe 11. At this time, the hot air carrying dust is discharged from the cabinet body 1 through the heat dissipation port 3.

[0039] When the cylinder output end moves the carriage 14 to the right, the moving carriage 14 slides on the surface of the inner rod 15 of the chute, and the moving carriage 14 drives the circular plate 16 to move synchronously. At this time, the circular plate 16 moving to the right pulls the corrugated pipe 10, and the extended corrugated pipe 10 starts to pump air. At this time, the gas inside the cabinet 1 enters the corrugated pipe 10 through the adsorption frame 18, the conduit 17 and the circular plate 16. The one-way valve is used to prevent the gas inside the corrugated pipe 10 from being discharged back into the cabinet 1 through the adsorption frame 18. At this time, the adsorption frame 18 filters most of the dust in the gas, and a small amount of dust enters the corrugated pipe 10 through the one-way valve. When the cylinder output end moves the carriage 14 to the left, the carriage 14 squeezes the corrugated pipe 10 by using the circular plate 16. The gas inside the corrugated pipe 10 is discharged by the one-way valve inside the exhaust pipe 11. The corrugated pipe 10 discharges the hot air and dust through the protective net 4 by using the exhaust pipe 11. While ensuring the heat dissipation of the cabinet 1, the adsorption frame 18 and the protective net 4 can also be used to adsorb the dust inside the cabinet 1.

[0040] Rotate the sleeve 12 in the reverse direction, and the rotating sleeve 12 moves out of the screw groove. At this time, pull the adsorption frame 18 to move between the two clamping frames 19 until the adsorption frame 18 is separated from the clamping frame 19. The elastic force of the spring 22 makes the baffle 21 close to the side plate. The moving baffle 21 pulls the front end of the rotating plate 25 to move. At this time, the front end of the top rotating plate 25 moves downward, and the front end of the bottom rotating plate 25 moves upward. The rotating rotating plate 25 uses the sliding rod and the connecting frame 29 to push the pressure rod 28 close to the inserting frame 23. When the inner end of the pressure rod 28 squeezes the inserting frame 23, the stressed inserting frame 23 cooperates with the elastic piece inside the pressurizing inner groove. At this time, the outer end of the inserting frame 23 gradually moves out of the vertical groove 24, completing the separation of the circular plate 16 and the carriage 14. At this time, the corrugated pipe 10 and the adsorption frame 18 can be taken out of the moving frame 7. At this time, the corrugated pipe 10 and the adsorption frame 18 are moved out of the cabinet 1 from the heat dissipation port 3, which is convenient for a comprehensive cleaning of the corrugated pipe 10 and the adsorption frame 18. Then, the cleaned corrugated pipe 10 and the adsorption frame 18 are reinstalled inside the moving frame 7 to ensure the continuous dust cleaning and heat dissipation effect of the cabinet 1.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
