Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically to a cabinet with a controllable opening and closing angle. Background Technology

[0002] With the development of power systems, the requirements for traditional distribution cabinets vary across different power-consuming locations, equipment, and loads. Therefore, distribution cabinets need to be rationally allocated and precisely controlled to ensure the normal operation of various electrical devices. As key equipment for power distribution and control, traditional distribution cabinets are typically non-adjustable or only have simple limit switches. They cannot be precisely fixed at the desired angle according to operational needs and are prone to accidental opening due to external forces, posing safety hazards. Over long-term use, dust and debris easily accumulate on the inner walls and ventilation vents of the cabinet, and insufficient dustproof design may even allow snakes and insects to intrude, affecting the reliability of equipment operation. Existing dust cleaning methods mostly rely on manual disassembly and cleaning, resulting in high maintenance costs and low efficiency.

[0003] To address the aforementioned shortcomings, this utility model provides a cabinet that combines controllable opening and closing angles with automated dust removal. The angle is precisely locked through a limiting device, and the dust removal device automatically removes accumulated dust and optimizes sealing, effectively solving the problems of inconvenient operation, difficult maintenance, and poor sealing in the prior art. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a cabinet with a controllable opening and closing angle, comprising: a cabinet body, a limiting device rotatably connected to the outer wall of the cabinet body, a dust outlet at the bottom of the cabinet body, a partition plate located inside the cabinet body away from the bottom, and a dust removal device on the inner wall of the cabinet body; the limiting device includes a guide rod, a top rod slidably connected to the inner wall of the guide rod, a spring fixedly connected to the outer wall of the top rod, a slidable connection between the outer wall of the top rod and the inner wall of the cabinet cover, a limiting gear located on the outside of the top rod, and a wedge-shaped locking block fixedly connected to the top rod near the limiting gear.

[0005] Preferably, the wedge-shaped locking block is slidably connected to the inner wall of the tooth groove of the limiting gear, the limiting gear is fixedly connected to the housing, the end of the spring away from the top rod is fixedly connected to the inner wall of the guide rod, and the inner wall of the housing cover is fixedly connected to the guide rod. When opening or closing the housing cover, the top rod needs to be manually pulled to overcome the spring force, so that the wedge-shaped locking block fixedly connected to the top rod disengages from the current tooth groove, and the housing cover can be rotated to the next limiting angle. After being released, the wedge-shaped locking block fixedly connected to the top rod is locked again into the new tooth groove, realizing multi-level angle control and avoiding accidental opening due to external force shaking.

[0006] Preferably, the dust removal device includes a drive motor, the output end of which is fixedly connected to a drive gear, and a drive belt is provided at the bottom end of the drive motor. A reciprocating lead screw is symmetrically arranged inside the drive belt, and a drive gear is fixedly connected to the outer wall of the reciprocating lead screw. A dust filter is provided outside the reciprocating lead screw. When the cabinet is placed outdoors for operation, the inner wall of the cabinet and the dust filter form a physical barrier, effectively preventing external snakes, insects, dust, and other foreign objects from entering the cabinet through the bottom dust outlet and heat dissipation vent. Simultaneously, the outline of the dust removal plate matches the shape of the inner wall of the cabinet and is sealed to the bottom of the cabinet and the partition via a corrugated pipe, further reducing gaps, enhancing the cabinet's sealing performance, and improving its anti-intrusion capability.

[0007] Preferably, the outer wall of the drive motor is fixedly connected to the inner wall of the housing, the drive gear and the transmission gear mesh with the belt, the top outer wall of the reciprocating screw is rotatably connected to the inner wall of the partition, the bottom end of the reciprocating screw is rotatably connected to the inner wall of the housing, and the outer wall of the dust filter is fixedly connected to the inner wall of the housing. When the drive motor is started, the reciprocating screw drives the dust removal plate to slide up and down through the transmission belt, removing the accumulated dust. The dust is discharged from the dust outlet at the bottom under the push of the dust removal plate.

[0008] Preferably, the outer wall of the dust filter is symmetrically provided with guide grooves, the inner wall of the guide groove is slidably connected with a dust removal plate, the inner wall of the dust removal plate is fixedly connected with a bearing, and the outer wall of the dust removal plate is symmetrically fixedly connected with a bellows. The bellows move and extend with the movement of the dust removal plate, sealing the reciprocating screw and preventing dust from entering the spiral groove of the reciprocating screw, thus ensuring the cleanliness of the transmission components.

[0009] Preferably, the inner wall of the bearing is threadedly connected to the outer wall of the reciprocating lead screw, the outer wall of the dust removal plate is slidably connected to the outer wall of the dust filter, the end of the bellows away from the dust removal plate is rotatably connected to the outer wall of the reciprocating lead screw, and the heat dissipation vents of the partition inside the box are kept ventilated during dust removal, which, together with the dust filter 37, intercepts large particles of impurities, thereby achieving the coordinated operation of heat dissipation and dust removal functions.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model achieves multi-level controllability of the lid opening and closing angle by setting a limiting device. The limiting device consists of a push rod, spring, limiting gear, and wedge-shaped locking block that work together. When the push rod is pulled to disengage the wedge-shaped locking block from the limiting gear groove, the lid can rotate freely. After the push rod is released, the wedge-shaped locking block engages with the corresponding groove under the spring force, forming a mechanical limit and fixing the current opening and closing angle. If the angle needs to be adjusted, the push rod can be pulled repeatedly to switch to the next limiting angle, meeting the precise control requirements of the lid opening and closing angle in different usage scenarios and avoiding operational inconvenience or safety hazards caused by uncontrollable angles.

[0012] 2. This utility model incorporates a dust removal device. Driven by a transmission motor, a reciprocating screw causes the dust removal plate to slide back and forth along the guide groove of the dust filter, adhering to the filter and the inner wall of the enclosure to remove accumulated dust. The dust is then discharged through the dust outlet, achieving automated dust removal and reducing manual maintenance costs. Simultaneously, the dust filter and the inner wall of the enclosure form a physical barrier, which, combined with the sealing design of the dust removal plate and the corrugated pipe, effectively prevents the intrusion of dust, insects, and other foreign objects, improving the enclosure's airtightness. The corrugated pipe also prevents dust from entering the spiral groove of the reciprocating screw, ensuring the cleanliness of the transmission components, extending the equipment's service life, and achieving synergistic operation of heat dissipation and dust removal functions, enhancing the enclosure's reliability in complex outdoor environments.

[0021] Example:

[0022] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a cabinet with a controllable opening and closing angle, comprising: a cabinet body 1, a limiting device 2 rotatably connected to the outer wall of the cabinet body 1, a dust outlet 12 opened at the bottom of the cabinet body 1, a partition 10 provided inside the cabinet body 1 away from the bottom, and a dust removal device 3 provided on the inner wall of the cabinet body 1; the limiting device 2 includes a guide rod 21, a top rod 20 slidably connected to the inner wall of the guide rod 21, a spring 22 fixedly connected to the outer wall of the top rod 20, a slidable connection between the outer wall of the top rod 20 and the inner wall of the cabinet cover 11, a limiting gear 23 provided on the outside of the top rod 20, and a wedge-shaped locking block 24 fixedly connected to the top rod 20 near the limiting gear 23.

[0023] The wedge-shaped locking block 24 is slidably connected to the inner wall of the tooth groove of the limiting gear 23. The limiting gear 23 is fixedly connected to the housing 1. The end of the spring 22 away from the top rod 20 is fixedly connected to the inner wall of the guide rod 21. The guide rod 21 is fixedly connected to the inner wall of the housing cover 11. When opening or closing the housing cover 11, the top rod 20 needs to be manually pulled to overcome the elastic force of the spring 22, so that the wedge-shaped locking block 24 fixedly connected to the top rod 20 is disengaged from the current tooth groove. Then the housing cover 11 can continue to be rotated to the next limiting angle. After being released, the wedge-shaped locking block 24 fixedly connected to the top rod 20 is locked again into the new tooth groove to achieve multi-level angle control.

[0024] The dust removal device 3 includes a drive motor 31, a drive gear 39 fixedly connected to the output end of the drive motor 31, a drive belt 33 at the bottom end of the drive motor 31, a reciprocating screw 32 symmetrically arranged inside the drive belt 33, a drive gear 30 fixedly connected to the outer wall of the reciprocating screw 32, and a dust filter 37 on the outside of the reciprocating screw 32. During dust removal, the drive motor 31 drives the drive gear 30 to rotate through the drive belt 33, and the reciprocating screw 32 meshing with the drive gear 30 drives the dust removal plate 34 to slide up and down along the guide groove 36 of the dust filter 37 to remove the accumulated dust.

[0025] The outer wall of the drive motor 31 is fixedly connected to the inner wall of the housing 1. The drive gear 39 and the transmission gear 30 mesh with the transmission belt 33. The top outer wall of the reciprocating screw 32 is rotatably connected to the inner wall of the partition 10. The bottom end of the reciprocating screw 32 is rotatably connected to the inner wall of the housing 1. The outer wall of the dust filter 37 is fixedly connected to the inner wall of the housing 1. The inner wall of the housing 1 and the dust filter 37 form a physical barrier, which can effectively block foreign objects such as snakes, insects, and dust from entering the housing through the bottom dust outlet 12 and the heat dissipation vent of the housing 1.

[0026] The outer wall of the dust filter 37 is symmetrically provided with guide grooves 36, the inner wall of the guide grooves 36 is slidably connected with a cleaning plate 34, the inner wall of the cleaning plate 34 is fixedly connected with a bearing 38, and the outer wall of the cleaning plate 34 is symmetrically fixedly connected with a corrugated pipe 35. The outline of the cleaning plate 34 is adapted to the shape of the inner wall of the box 1, and it is sealed to the bottom of the box 1 and the partition 10 through the corrugated pipe 35, so that the cleaning effect is better.

[0027] The inner wall of the bearing 38 is threadedly connected to the outer wall of the reciprocating screw 32, the outer wall of the dust removal plate 34 is slidably connected to the outer wall of the dust filter 37, and the end of the bellows 35 away from the dust removal plate 34 is rotatably connected to the outer wall of the reciprocating screw 32. When cleaning the accumulated dust, the bellows 35 moves and extends with the dust removal plate 34, sealing the reciprocating screw 32 and preventing dust from accumulating in the spiral groove of the reciprocating screw 32, thus affecting its service life.

[0028] Working principle:

[0029] In use, the opening and closing angle of the cover 11 is multi-level controllable through the cooperation of the limit gear 23 and the top rod 20. The internal dust is cleaned by the reciprocating motion of the reciprocating screw 32 and the dust cleaning plate 34, which improves the convenience and reliability of the cabinet.

[0030] When opening the lid 11, the push rod 20 inside the guide rod 21 fixed on the inner wall of the lid 11 must be manually pulled outwards first, so that the wedge-shaped locking block 24 of the push rod 20 leaves the tooth groove of the limiting gear 23. At this time, the spring 22 inside the guide rod 21 is in a compressed state. As the lid 11 rotates, the push rod 20 gradually crosses the tooth top of the limiting gear 23, providing a sliding guide for opening the lid 11.

[0031] When the lid 11 is rotated to the target angle and the opening / closing angle needs to be fixed, the push rod 20 is released. The wedge-shaped locking block 24, which is fixedly connected to the push rod 20, is engaged in the corresponding tooth groove of the limiting gear 23 under the action of the spring 22. The wedge-shaped locking block 24 and the tooth groove are tightly engaged to form a mechanical limit, thereby fixing the opening / closing angle of the lid 11. If the angle needs to be adjusted, the push rod 20 needs to be manually pulled again to overcome the spring 22, so that the wedge-shaped locking block 24, which is fixedly connected to the push rod 20, is disengaged from the current tooth groove. Then the lid 11 can continue to be rotated to the next limiting angle. After being released, the wedge-shaped locking block 24, which is fixedly connected to the push rod 20, is engaged in the new tooth groove to achieve locking, realizing multi-level angle controllability.

[0032] When closing the lid 11, the user pulls the push rod 20 again, causing the wedge-shaped locking block 24, which is fixedly connected to the push rod 20, to disengage from the tooth groove of the limiting gear 23, and compresses the spring 22 again. When the lid 11 is completely in contact with the box body 1, the push rod 20 is released. Under the action of the spring 22, the wedge-shaped locking block 24, which is fixedly connected to the push rod 20, engages with the tooth groove of the limiting gear 23 at its initial position. The elastic force of the spring 22 ensures that the end of the push rod 20 meshes with the tooth groove of the limiting gear 23, maintaining the closed state of the lid 11 and preventing accidental opening due to external force shaking.

[0033] When the cabinet is placed outdoors for operation, the inner wall of the cabinet 1 and the dust filter 37 form a physical barrier, which can effectively prevent foreign objects such as snakes, insects, and dust from entering the cabinet through the dust outlet 12 and heat dissipation vent at the bottom of the cabinet 1. At the same time, the outline of the dust removal plate 34 is adapted to the shape of the inner wall of the cabinet 1, and is sealed to the bottom of the cabinet 1 and the partition 10 through the corrugated pipe 35, further reducing gaps, enhancing the airtightness of the cabinet, and improving the anti-intrusion capability.

[0034] When cleaning dust, the drive motor 31 is started, which drives the drive gear 30 to rotate through the drive belt 33. The reciprocating screw 32, which meshes with the drive gear 30, drives the cleaning plate 34 to slide up and down along the guide groove 36 of the dust filter 37. The cleaning plate 34 fits against the dust filter 37 and the inner wall of the box 1 to remove the accumulated dust. The dust is pushed by the cleaning plate 34 and discharged through the dust outlet 12 at the bottom of the box 1. The corrugated pipe 35 moves and extends with the movement of the cleaning plate 34, sealing the reciprocating screw 32 and preventing dust from entering the spiral groove of the reciprocating screw 32, thus ensuring the cleanliness of the transmission components. The heat dissipation vents of the partition 10 inside the box 1 are kept ventilated during dust cleaning. Together with the dust filter 37, it intercepts large particles of impurities, realizing the coordinated operation of heat dissipation and dust cleaning functions.
