Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, specifically a 10kV switchgear with high-efficiency dust removal. Background Technology

[0002] In modern power supply networks, 10kV switchgear, as a crucial piece of equipment for power distribution and control, is widely used in various substations, distribution rooms, and industrial and civil power systems. Its reliable operation is essential for ensuring stable power transmission. However, 10kV switchgear generates a significant amount of heat during operation. To prevent damage from overheating, heat dissipation design is a key aspect of switchgear structural design. Typically, switchgear is equipped with dedicated heat dissipation channels, vents, and other heat dissipation facilities. However, dust is ubiquitous in the air. When the switchgear dissipates heat, airflow inevitably brings dust into the heat dissipation areas, leading to dust accumulation. This dust accumulation affects heat dissipation efficiency, causing the internal temperature of the switchgear to rise, accelerating the aging of electrical components, and reducing their lifespan.

[0003] To address the aforementioned problems, this utility model proposes a 10kV switchgear with high-efficiency dust removal. Utility Model Content

[0004] The technical problem this invention aims to solve is that dust accumulation at the heat dissipation vents affects heat dissipation efficiency, leading to increased internal temperature of the switchgear, accelerated aging of electrical components, and reduced service life. This invention proposes a 10kV switchgear with high-efficiency dust removal.

[0005] To solve the above technical problems, the technical solution adopted by this utility model is: a 10kV switchgear with high efficiency dust removal, including a cabinet and electrical components installed in the cabinet cavity. The outer wall of the cabinet is provided with heat dissipation vents, the inner wall of the heat dissipation vents is provided with heat dissipation mesh, and the outer wall of the heat dissipation mesh is fitted with a dust removal mechanism, which is used to remove dust from the surface of the heat dissipation mesh.

[0006] The dust removal mechanism includes side-mounted blocks installed on the side wall of the cabinet. There are two sets of side-mounted blocks, and the two sets of side-mounted blocks are symmetrically distributed about the center of the cabinet. Each set of side-mounted blocks has an upper connecting block and a lower connecting block fixedly connected to both ends. The upper connecting block and the lower connecting block are fixedly connected to the side wall of the cabinet. A threaded rod is rotatably connected between the upper connecting block and the lower connecting block. A movable block is threadedly connected to the outer wall of the threaded rod. A cleaning block is provided on the inner wall of the movable block. The cleaning block is attached to the heat dissipation mesh. An opening is opened on the outer wall of the cleaning block. The cleaning block is a component made of rubber material and has a hollow structure inside.

[0007] Furthermore, the movable block 35 has a U-shaped structure, and the movable block slides in conjunction with the side mounting block.

[0008] Furthermore, the bottom of the movable block is provided with a movable groove, and a slider body is slidably connected to the inner wall of the movable groove. The slider body is fixedly connected to the cleaning block.

[0009] Furthermore, an elastic element is fixedly connected to the bottom of the cavity of the movable groove, and one end of the elastic element is fixedly connected to the slider body.

[0010] Furthermore, a top block body is fixedly connected to the outer wall of the cabinet. The outer wall of the top block body has an arc-shaped structure, and the top block body is located above the heat dissipation vent.

[0011] Furthermore, when the upper wall of the movable block is attached to the upper connecting block, the cleaning block is attached to the outer wall of the top block body.

[0012] Compared with the prior art, the beneficial effects of this utility model include: the threaded rod and the movable block are connected by a thread, and the movable block has a U-shaped structure and slides in cooperation with the side mounting block. Therefore, when the threaded rod rotates, the movable block will move linearly along the track of the side mounting block. During the movement of the movable block, the cleaning block set on its inner wall is always in close contact with the heat dissipation mesh. The cleaning block can effectively scrape off the dust attached to the surface of the heat dissipation mesh. With the continuous rotation of the threaded rod, the movable block moves from one end of the heat dissipation mesh to the other end, completing the comprehensive cleaning of the surface of the heat dissipation mesh, peeling the dust off the heat dissipation mesh and removing it from the heat dissipation area. This avoids the accumulation of dust from affecting the heat dissipation efficiency and causing electrical faults. It solves the problem that dust accumulation not only affects the heat dissipation efficiency, but also causes the internal temperature of the switch cabinet to rise, accelerates the aging of electrical components, and reduces their service life.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0020] Please see Figures 1-4 To address the problem that dust accumulation not only affects heat dissipation efficiency, leading to increased internal temperature of the switchgear, accelerating the aging of electrical components, and reducing their lifespan, the following preferred technical solutions are provided:

[0021] A high-efficiency dust removal 10kV switchgear includes a cabinet 1 and electrical components 2 installed inside the cabinet 1. The outer wall of the cabinet 1 has heat dissipation vents, and the inner wall of the vents is fitted with a heat dissipation mesh 4. A dust removal mechanism 3 is attached to the outer wall of the heat dissipation mesh 4 to remove dust from its surface. The dust removal mechanism 3 includes side-mounted blocks 31 installed on the side wall of the cabinet 1. Two sets of side-mounted blocks 31 are provided, and both sets are symmetrically distributed about the center of the cabinet 1. Each set of side-mounted blocks 31 has an upper connecting block 32 and a lower connecting block 33 fixedly connected to its two ends. The upper connecting block 32... Both the upper and lower connecting blocks 33 are fixedly connected to the side wall of the cabinet 1. A threaded rod 34 is rotatably connected between the upper connecting block 32 and the lower connecting block 33. A movable block 35 is threadedly connected to the outer wall of the threaded rod 34. When the threaded rod 34 rotates, according to the thread transmission principle, the movable block 35 threadedly connected to it will slide along the track formed by the side mounting block 31. The position of the movable block 35 can be precisely controlled by rotation. A cleaning block 36 is provided on the inner wall of the movable block 35. The cleaning block 36 is attached to the heat dissipation mesh 4. The movable block 35 has a U-shaped structure and slides in cooperation with the side mounting block 31.

[0022] Specifically, when dust removal is required, the threaded rod 34 is connected to an external motor. Since the threaded rod 34 and the movable block 35 are connected by a thread, and the movable block 35 has a U-shaped structure and slides in cooperation with the side mounting block 31, when the threaded rod 34 rotates, the movable block 35 will move linearly along the track of the side mounting block 31. During the movement of the movable block 35, the cleaning block 36 set on its inner wall is always in close contact with the heat dissipation mesh 4. The cleaning block 36 can effectively scrape off the dust attached to the surface of the heat dissipation mesh 4. As the threaded rod 34 continues to rotate, the movable block 35 moves from one end of the heat dissipation mesh 4 to the other end, completing a comprehensive cleaning of the surface of the heat dissipation mesh 4, peeling the dust off the heat dissipation mesh 4 and removing it from the heat dissipation area. This avoids dust accumulation affecting heat dissipation efficiency and causing electrical faults. It solves the problem that dust accumulation not only affects heat dissipation efficiency, but also causes the internal temperature of the switch cabinet to rise, accelerates the aging of electrical components, and reduces their service life.

[0023] The bottom of the movable block 35 is provided with a movable groove 38, and the inner wall of the movable groove 38 is slidably connected to a slider body 37. The slider body 37 is fixedly connected to the cleaning block 36. The bottom of the cavity of the movable groove 38 is fixedly connected to an elastic element 39, and one end of the elastic element 39 is fixedly connected to the slider body 37.

[0024] Specifically, when the cleaning block 36 is cleaning the heat dissipation mesh 4, if the surface of the heat dissipation mesh 4 is uneven or there are large dust particles obstructing it, the cleaning block 36 can slide in the movable groove 38 through the slider body 37 to compress the elastic element 39, thereby achieving adaptive adjustment. The elastic element 39 always provides the cleaning block 36 with a force that keeps it in close contact with the surface of the heat dissipation mesh 4, ensuring that the cleaning block 36 can maintain good contact with the heat dissipation mesh 4 under any circumstances, effectively removing dust and improving the dust removal effect.

[0025] The outer wall of the cabinet 1 is fixedly connected to the top block body 5. The outer wall of the top block body 5 has an arc-shaped structure. The top block body 5 is located at the upper end of the heat dissipation vent. When the upper wall of the movable block 35 is attached to the upper connecting block 32, the cleaning block 36 is attached to the outer wall of the top block body 5. The outer wall of the cleaning block 36 has an opening. The cleaning block 36 is a component made of rubber or special fiber material, and the interior of the cleaning block 36 has a hollow structure.

[0026] Specifically, because the cleaning block 36 is made of a special rubber material, it has a certain degree of elasticity and deformation recovery ability. When the cleaning block 36 moves along the arc-shaped outer wall of the top block body 5 and gradually detaches, a relative negative pressure will be formed inside the cleaning block 36 under the squeezing action of the top block body 5. This negative pressure generates suction, which can adsorb the dust that adheres to the surface of the heat dissipation mesh 4 during cleaning and the surrounding suspended dust into the cavity of the cleaning block 36, further improving the dust collection effect of the cleaning block 36, preventing dust from flying around the switch cabinet again, and ensuring the efficiency and thoroughness of the dust removal work.
