Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinet dust removal and power distribution cabinet, and specifically, to a dust removal device for a power distribution cabinet and a low-voltage power distribution cabinet. Background Art

[0002] When a low-voltage distribution cabinet is used for a long time, dust will adhere to its interior. Too much accumulated dust will affect the operation of internal components and even cause the entire distribution cabinet to be damaged and unable to continue to be used. Therefore, the interior needs to be vacuumed and dust removed at regular intervals.

[0003] The existing dust removal method basically involves opening the cabinet and manually using a handheld vacuum cleaner to remove dust, which is time-consuming and labor-intensive. The vacuum cleaner built into the cabinet is fixed in position, has a poor dust removal effect, and cannot be moved to dissipate heat from the cabinet. Summary of the invention

[0004] The present invention proposes a dust removal device for a distribution cabinet and a low-voltage distribution cabinet. The dust removal device can move up and down in the distribution cabinet, and can knock on the side walls of the distribution cabinet while moving, so that the dust accumulated on the side walls can be thoroughly cleaned. After the cleaning is completed, the switch door can be closed to prevent dust from overflowing; the interior of the distribution cabinet can also be cooled in a mobile manner.

[0005] To this end, the present invention provides a dust removal device for a distribution cabinet, comprising a main body, a dust removal filter cartridge is provided inside the main body, a negative pressure mechanism connected to the interior of the main body is provided at the lower portion of the main body, a dust hood is provided at the upper end of the main body, a switch door is provided inside the dust hood, a linkage mechanism for pulling the main body and the switch door is provided inside the dust hood, a knocking mechanism is provided between the upper end of the main body and the dust hood, and also includes a switch door locking and heat dissipation mechanism arranged on the dust hood.

[0006] By adopting the above technical solution: when performing dust removal, the switch door is first opened through the action of the linkage mechanism, and then the linkage mechanism continues to pull up to drive the main body to slide up and down. While the main body and the side wall of the distribution cabinet slide relative to each other, the knocking mechanism intermittently knocks on the side wall of the distribution cabinet to shake off the dust thereon. The mobile and knocking dust removal improves the dust removal efficiency; after the dust removal is completed, the switch door is closed to prevent dust from overflowing; when the inside of the distribution cabinet needs to be cooled down, the switch door locks the heat dissipation mechanism to lock the switch door first, and the switch door is in a closed state. Then, while the linkage mechanism drives the main body to move up and down, the switch door locks the heat dissipation mechanism to pass cold air to the inside of the cabinet, so as to quickly cool down the inside of the cabinet.

[0007] Optionally, the switch door is arranged at the upper opening of the dust filter cartridge, and the linkage mechanism includes a mounting plate connected to the dust hood through a support rod, a pull rod is slidably provided on the mounting plate, the lower end of the pull rod is connected to the switch door, and an elastic member is sleeved on the pull rod between the switch door and the mounting plate.

[0008] By adopting the above technical solution: through the movement of the pull rod, firstly, part of the elastic force of the elastic member is overcome to open the switch door. Of course, the elastic force of the elastic member that tops the switch door should be smaller than the overall gravity of the device. When the switch door is opened, the pull rod continues to be pulled up, and the elastic action of the elastic member can drive the device to move relative to the cabinet.

[0009] Optionally, the knocking mechanism includes a mounting column arranged at the upper end of the main body, the upper end of the mounting column is rotatably connected to a Z-shaped rod, one end of the Z-shaped rod is connected to the dust hood through an elastic component, and the other end of the Z-shaped rod is provided with a touch portion.

[0010] By adopting the above technical solution: during the upward movement of the main body, since a touch component is provided on the inner wall of the cabinet, the touch component can stretch the elastic component after contacting the touch part. When the contact is released, the touch part can hit the inner wall of the cabinet under the rebound force of the elastic component, thereby shaking off the dust.

[0011] Optionally, the main body is slidably connected to the inner wall of the distribution cabinet through a sliding assembly, the elastic assembly includes a spring with one end connected to the end of the Z-shaped rod and the other end connected to the outer wall of the dust hood, and the sliding assembly includes a positioning groove arranged on the main body and a positioning rail arranged on the inner wall of the distribution cabinet.

[0012] By adopting the above technical solution, the movement of the main body can be positioned through the cooperation of the positioning slide rail and the positioning slide groove, so that it can move up and down relative to the cabinet.

[0013] Optionally, the door lock heat dissipation mechanism includes a pneumatic cavity arranged on the dust cover, a resilient trigger for locking the door is arranged at the lower part of the pneumatic cavity, and also includes a plurality of air outlets arranged on the pneumatic cavity, and the pneumatic cavity is connected to an external air source through a hose;

[0014] The elastic triggering member comprises a piston rod slidably arranged at the bottom of the pneumatic cavity, and a tension spring is arranged between the piston rod and the bottom of the pneumatic cavity.

[0015] By adopting the above technical solution: the pneumatic cavity can temporarily store cold air, and secondly, it can drive the piston rod to lock the door. Then the pull rod can pull the body to move. At the same time, cold air is sprayed through the air outlet to quickly cool down the inside of the cabinet.

[0016] Optionally, the interior of the main body is hollow, and a pedestal is provided at the bottom of the main body. The dust filter cartridge is clamped on the pedestal, and a gas channel is formed between the dust filter cartridge and the inner wall of the main body. The gas channel is connected to a negative pressure mechanism, and a supporting platform for clamping a switch door is provided on the upper part of the dust filter cartridge.

[0017] By adopting the above technical solution: the vertebral platform is convenient for fixing the dust filter cartridge. Under the suction of the negative pressure mechanism, the airflow carrying dust passes through the dust filter cartridge for dust removal. The supporting platform is used to support the switch door when the pull rod is pushed downward, thereby driving the main body to move downward.

[0018] Optionally, the Z-shaped rod is rotatably connected to the upper end of the mounting column via a limiting assembly.

[0019] Optionally, the limit assembly includes a connecting rod connected to the upper end of the mounting column, the connecting rod is provided with an upper limit plate and a lower limit plate, and the Z-shaped rod is rotatably connected to the connecting rod between the upper limit plate and the lower limit plate.

[0020] By adopting the above technical solution, the Z-shaped rod can be swung around the connecting rod, so as to knock the inner wall of the distribution cabinet.

[0021] The second aspect of the present invention provides a low-voltage distribution cabinet, including a cabinet body, in which the above-mentioned dust removal device is slidably connected, and also includes a lifting power part connected to the pull rod of the linkage mechanism. A positioning slide rail is provided on the inner wall of the cabinet body, and also includes a touch component arranged on the inner wall of the cabinet body on both sides of the positioning slide rail.

[0022] Optionally, the trigger assembly includes a plurality of trigger protrusions arranged on the inner wall of the cabinet.

[0023] By adopting the above technical solution, the touching protrusion intermittently contacts the touching part, stretches the elastic component to store force, and can intermittently knock on the inner wall of the cabinet.

[0024] The working principle and beneficial effects of the present invention are:

[0025] 1. When performing dust removal, first open the switch door through the linkage mechanism, and then the linkage mechanism continues to pull up to drive the body to slide up and down. While the body and the side wall of the distribution cabinet slide relative to each other, the knocking mechanism intermittently knocks on the side wall of the distribution cabinet to shake off the dust thereon. The mobile and knocking dust removal improves the dust removal efficiency. After the dust removal is completed, the switch door is closed to prevent dust from overflowing. When it is necessary to cool down the inside of the distribution cabinet, the switch door locks the heat dissipation mechanism to lock the switch door first, and the switch door is in a closed state. Then, while the linkage mechanism drives the body to move up and down, the switch door locks the heat dissipation mechanism to pass cold air into the cabinet, which is convenient for quickly cooling down the inside of the cabinet.

[0026] 2. By moving the pull rod, first overcome part of the elastic force of the elastic member to open the switch door. Of course, the elastic force of the elastic member that tops the switch door should be smaller than the overall gravity of the device. When the switch door is opened, the pull rod continues to be pulled up, and the elastic action of the elastic member can drive the device to move relative to the cabinet.

[0027] 3. The pneumatic cavity can temporarily store cold air and drive the piston rod to lock the door. The pull rod can then pull the body to move. While moving, cold air is sprayed through the air outlet to quickly cool down the interior of the cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figure 1-Figure 5 As shown, the first aspect of this embodiment provides a dust removal device for a power distribution cabinet, including a main body 100, wherein a dust filter cartridge 200 is provided inside the main body 100, a negative pressure mechanism 300 connected to the inside of the main body 100 is provided at the lower part of the main body 100, a dust hood 400 is provided at the upper end of the main body 100, a switch door 500 is provided inside the dust hood 400, a linkage mechanism 600 for pulling the main body 100 and the switch door 500 is provided inside the dust hood 400, a knocking mechanism 700 is provided between the upper end of the main body 100 and the dust hood 400, and also includes a switch door locking and heat dissipation mechanism 800 arranged on the dust hood 400.

[0037] The basic principle of this embodiment is as follows: when performing dust removal, the switch door 500 is first opened through the action of the linkage mechanism 600, and then the linkage mechanism 600 continues to pull up to drive the main body 100 to slide up and down. While the main body 100 slides relative to the side wall of the distribution cabinet, the knocking mechanism 700 intermittently knocks on the side wall of the distribution cabinet to shake off the dust thereon. The mobile and knocking dust removal improves the dust removal efficiency. After the dust removal is completed, the switch door 500 is closed to prevent dust from overflowing. When it is necessary to cool down the inside of the distribution cabinet, the switch door locking heat dissipation mechanism 800 first locks the switch door 500, and the switch door 500 is in a closed state. Then, while the linkage mechanism 600 drives the main body 100 to move up and down, the switch door locking heat dissipation mechanism 800 passes cold air into the cabinet 900, so as to quickly cool down the inside of the cabinet 900.

[0038] The switch door 500 in this embodiment is arranged at the upper opening of the dust filter cartridge 200, and the linkage mechanism 600 includes a mounting plate 620 connected to the dust hood 400 through a support rod 610, and a pull rod 630 is slidably penetrated on the mounting plate 620, and the lower end of the pull rod 630 is connected to the switch door 500, and an elastic member 640 is sleeved on the pull rod 630 between the switch door 500 and the mounting plate 620; through the movement of the pull rod 630, the switch door 500 is first opened by overcoming part of the elastic force of the elastic member 640, of course, the elastic force of the elastic member 640 that contacts the switch door 500 should be less than the overall gravity of the device, and when the switch door 500 is opened, the pull rod 630 continues to pull up, and the device can be driven to move relative to the cabinet 900 under the elastic action of the elastic member 640.

[0039] The knocking mechanism 700 in this embodiment includes a mounting column 710 arranged at the upper end of the main body 100, and the upper end of the mounting column 710 is rotatably connected to a Z-shaped rod 720, one end of the Z-shaped rod 720 is connected to the dust hood 400 through an elastic component, and the other end of the Z-shaped rod 720 is provided with a touch portion 730.

[0040] During the upward movement of the main body 100, since a touch component is provided on the inner wall of the cabinet 900, the touch component can stretch the elastic component after contacting the touch part 730. When the contact is released, the touch part 730 can hit the inner wall of the cabinet 900 under the rebound force of the elastic component, thereby shaking off the dust.

[0041] The main body 100 is slidably connected to the inner wall of the distribution cabinet through a sliding component. The elastic component includes a spring 740 with one end connected to the end of the Z-shaped rod 720 and the other end connected to the outer wall of the dust cover 400. The sliding component includes a positioning groove 110 arranged on the main body 100 and a positioning rail 120 arranged on the inner wall of the distribution cabinet; the movement of the main body 100 can be positioned by cooperating with the positioning rail 120 and the positioning groove 110, so that it can move up and down relative to the cabinet 900.

[0042] The switch door locking and heat dissipation mechanism 800 in this embodiment includes a pneumatic cavity 810 arranged on the dust hood 400, and the lower part of the pneumatic cavity 810 is provided with an elastic trigger for locking the switch door 500, and also includes a plurality of air outlet holes 820 arranged on the pneumatic cavity 810. The pneumatic cavity 810 is connected to an external air source through a hose, and the elastic trigger includes a piston rod 830 slidably arranged at the bottom of the pneumatic cavity 810, and a tension spring 840 is provided between the piston rod 830 and the bottom of the pneumatic cavity 810.

[0043] The pneumatic cavity 810 can temporarily store cold air and drive the piston rod 830 to lock the switch door 500. Then the pull rod 630 can pull the main body 100 to move. While moving, cold air is sprayed through the air outlet 820 to quickly cool the interior of the cabinet 900. When cold air with a certain pressure is introduced into the pneumatic cavity 810, the airflow first pushes the piston rod 830 to move downward and extend to support the switch door 500. Then the pull rod 630 is pulled and the switch door 500 is no longer opened. This can prevent dust from spilling out and pull the pull rod 630 to drive the entire dust removal device to move upward for cooling.

[0044] The main body 100 in this embodiment is hollow inside, and a prism 130 is provided at the bottom of the main body 100. The dust filter cartridge 200 is clamped on the prism 130. A gas channel 140 is formed between the dust filter cartridge 200 and the inner wall of the main body 100. The gas channel 140 is connected to the negative pressure mechanism 300. The upper part of the dust filter cartridge 200 is provided with a supporting platform 210 for clamping the switch door 500; the prism 130 is convenient for fixing the dust filter cartridge 200. Under the suction force of the negative pressure mechanism 300, the airflow carrying dust passes through the dust filter cartridge 200 for dust removal. The supporting platform 210 is used to support the switch door 500 when the pull rod 630 is pushed downward, thereby driving the main body 100 to move downward.

[0045] The Z-shaped rod 720 is rotatably connected to the upper end of the mounting column 710 through a limiting assembly. The limiting assembly includes a connecting rod 750 connected to the upper end of the mounting column 710. The connecting rod 750 is provided with an upper limit plate 760 and a lower limit plate 770. The Z-shaped rod 720 is rotatably connected to the connecting rod 750 between the upper limit plate 760 and the lower limit plate 770, so that the Z-shaped rod 720 can swing around the connecting rod 750, thereby hitting the inner wall of the distribution cabinet.

[0046] The second aspect of this embodiment provides a low-voltage distribution cabinet, including a cabinet body 900, in which the above-mentioned dust removal device is slidably connected, and also includes a lifting power part 910 connected to the pull rod 630 of the linkage mechanism 600. A positioning slide rail 120 is provided on the inner wall of the cabinet body 900, and also includes a touch component arranged on the inner wall of the cabinet body 900 on both sides of the positioning slide rail 120.

[0047] The touch assembly includes a plurality of touch protrusions 920 disposed on the inner wall of the cabinet 900 . The touch protrusions 920 intermittently contact the touch portion 730 , stretching the elastic assembly to store force, and can intermittently knock on the inner wall of the cabinet 900 .
