Description

Technical Field

[0001] This utility model belongs to the field of busbar technology, specifically a busbar with a double dustproof structure. Background Technology

[0002] Busbar trunking is a closed metal device composed of copper or aluminum busbar columns. It typically uses copper or aluminum busbars as the conductive medium, offering high conductivity and current carrying capacity. Its outer shell is generally made of metal, such as aluminum-magnesium alloy, serving to protect the conductors and provide insulation. It also facilitates installation and fixation. Primarily used to distribute large power to various components in distributed systems, it has gradually replaced electrical wires and cables in indoor low-voltage power transmission trunk line projects. It can be flexibly arranged and installed according to actual needs, is easy to disassemble and maintain, and can adapt to different environmental conditions. However, in existing busbar trunking systems, the copper busbars are prone to shaking, which can cause the electrical components connected to the copper busbars to loosen, affecting the normal operation of the busbar trunking. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a busbar trunking with a double dustproof structure, which solves the problem that the copper busbars on the busbar trunking are prone to shaking during use, which leads to the loosening of electrical components connected to the copper busbars and affects the normal use of the busbar trunking.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a busbar trunking with a dual dustproof structure, comprising a busbar trunking body, four copper busbars fixedly connected to both sides of the busbar trunking body, four sliding grooves respectively opened on the two end surfaces around the busbar trunking body, protective frames slidably connected to both sides of the busbar trunking body, four elastic blocks fixedly connected to the inner wall of each protective frame, the elastic blocks slidably connected to the inner wall of the sliding groove, elastic sealing gaskets fixedly connected to both sides of each elastic block on the inner wall of each protective frame, the elastic sealing gaskets being tightly attached to the surface of the busbar trunking body, four through grooves opened on the side of each protective frame away from the elastic blocks, the through grooves corresponding to the positions of the copper busbars and penetrating the protective frame, five springs fixedly connected to the inner walls of both sides of each through groove, a same limiting plate installed at one end of the five springs on the same side, the limiting plate slidably connected to the inner wall of the through groove, and a rubber inclined block fixedly connected to the side of each limiting plate away from the spring, the rubber inclined block slidably connected to the inside of the through groove.

[0005] As a further embodiment of this utility model: heat dissipation mesh is fixedly connected to both sides of the busbar trunking body, and mounting plates are fixedly connected to both sides of the heat dissipation mesh on the busbar trunking body.

[0006] As a further embodiment of this utility model: a threaded rod is rotatably connected between the mounting plates via bearings, and a motor is installed at one end of the threaded rod passing through the mounting plate.

[0007] As a further embodiment of this utility model: the motor is fixedly connected to the mounting plate, and a movable plate is threadedly connected to the threaded rod.

[0008] As a further embodiment of this utility model: a cleaning brush is fixedly connected to one side of the movable plate, and the cleaning brush is in close contact with the heat dissipation mesh.

[0009] As a further embodiment of this utility model: limit rods are symmetrically fixedly installed on both sides of the threaded rod between the two mounting plates, and the limit rods are slidably connected to the movable plate through the plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This busbar trunking with a dual dustproof structure, through the setting of a protective frame, spring, and rubber inclined blocks, allows the protective frame to be pulled during use. This causes the protective frame to slide along the elastic block in the groove. As the protective frame moves, the copper busbar presses against the inclined surface of the rubber inclined block. The rubber inclined block, in turn, moves the limiting plate to both sides of the groove, thereby pressing the limiting plate against the spring inside the groove. The spring, through its elastic force, causes the rubber inclined block to press tightly against the surface of the copper busbar, fixing and clamping the copper busbar to prevent it from shaking and improving the stability of the busbar trunking during use.

[0012] 2. This busbar trunking with a dual dustproof structure is equipped with a motor, a threaded rod, a movable plate, and a heat dissipation mesh. The motor drives the threaded rod to rotate through the output shaft, which in turn drives the movable plate to move. During the movement, the movable plate causes the cleaning brush to slide on the surface of the heat dissipation mesh, thereby allowing the cleaning brush to sweep away the dust adhering to the surface of the heat dissipation mesh and prevent the heat dissipation mesh from becoming clogged and affecting its normal heat dissipation.

Detailed Implementation

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: a busbar trunking with a double dustproof structure, including a busbar trunking body 1, with heat dissipation mesh 11 fixedly connected to both sides of the busbar trunking body 1, and mounting plates 12 fixedly connected to both sides of the busbar trunking body 1 on the heat dissipation mesh 11. By setting the heat dissipation mesh 11, the heat dissipation mesh 11 can ensure normal air circulation between the inside of the busbar trunking body 1 and the outside air, so that the hot air inside the busbar trunking body 1 can be discharged through the heat dissipation mesh 11 to dissipate heat from the busbar trunking body 1.

[0019] A threaded rod 14 is rotatably connected between the mounting plates 12 via bearings. One end of the threaded rod 14 passes through the mounting plate 12 and is equipped with a motor 13. The motor 13 is fixedly connected to the mounting plate 12. A movable plate 15 is threadedly connected to the outside of the threaded rod 14. By setting the motor 13, the motor 13 controls the rotation of the threaded rod 14 through the output shaft, so that the threaded rod 14 can drive the movable plate 15 to move between the two mounting plates 12.

[0020] A cleaning brush 16 is fixedly connected to one side of the movable plate 15. The cleaning brush 16 is in close contact with the heat dissipation mesh 11. By setting the cleaning brush 16, the cleaning brush 16 can move together with the movable plate 15, so that the movable plate 15 can slide on the surface of the heat dissipation mesh 11 and scrape off the dust attached to the surface of the heat dissipation mesh 11 to prevent the heat dissipation mesh 11 from being blocked.

[0021] Limiting rods 17 are symmetrically fixed on both sides of the threaded rod 14 between the two mounting plates 12. The limiting rods 17 are slidably connected to the movable plate 15. By setting the limiting rods 17, the motor 13 drives the movable plate 15 to move through the threaded rod 14, so that the movable plate 15 can slide outside the limiting rods 17, thereby limiting the movable plate 15 by the limiting rods 17, making the movement of the movable plate 15 more stable.

[0022] Four copper busbars 3 are fixedly connected to both sides of the busbar trunking body 1. Four sliding grooves 2 are opened on the two ends of the busbar trunking body 1. Protective frames 4 are slidably connected to both sides of the busbar trunking body 1. By setting the protective frames 4, when the busbar trunking body 1 is idle, the protective frames 4 can store the copper busbars 3 inside the protective frames 4, so that the protective frames 4 can protect the copper busbars 3.

[0023] Four elastic blocks 5 are fixedly connected to the inner wall of each protective frame 4. The elastic blocks 5 are slidably connected to the inner wall of the slide 2. By setting the elastic blocks 5, the elastic blocks 5 slide in the slide 2 as the protective frame 4 moves, so that the slide 2 can limit the protective frame 4 through the elastic blocks 5, making the movement of the protective frame 4 more stable.

[0024] Each protective frame 4 has an elastic sealing gasket 6 fixedly connected to both sides of each elastic block 5 on its inner wall. The elastic sealing gasket 6 is in close contact with the surface of the busbar trunking body 1. By setting the elastic sealing gasket 6, the elastic sealing gasket 6 slides on the surface of the busbar trunking body 1 as the protective frame 4 moves, thereby isolating the inside of the protective frame 4 from the outside world and preventing dust from entering the interior of the elastic sealing gasket 6 and affecting the normal use of the copper busbar 3.

[0025] Each protective frame 4 has four through slots 7 on the side away from the elastic block 5. The through slots 7 correspond to the positions of the copper busbar 3 and pass through the protective frame 4. Five springs 8 are fixedly connected to the inner walls on both sides of each through slot 7. The same limiting plate 9 is installed at one end of the five springs 8 on the same side. The limiting plate 9 is slidably connected to the inner wall of the through slot 7. A rubber inclined block 10 is fixedly connected to the side of each limiting plate 9 away from the spring 8. The rubber inclined block 10 is slidably connected to the inside of the through slot 7. By setting the springs 8, when the rubber inclined block 10 is pressed against both sides of the copper busbar 3, the rubber inclined block 10 can squeeze the spring 8 through the limiting plate 9, thereby causing the spring 8 to deform and generate relative elastic force. The spring 8 drives the rubber inclined block 10 to press tightly against both sides of the copper busbar 3 through the elastic force, thereby achieving the sealing treatment of the through slot 7.

[0026] The working principle of this utility model is as follows:

[0027] When not in use, the protective frame 4 can house the copper busbars 3 on both sides of the busbar trunking body 1, thus protecting the copper busbars 3. In use, pushing the protective frame 4 moves it towards the center of the busbar trunking body 1. The protective frame 4 causes the elastic sealing gasket 6 to slide on the surface of the busbar trunking body 1, isolating the inside of the protective frame 4 from the outside. This allows the copper busbars 3 on both sides of the busbar trunking body 1 to press against the rubber inclined blocks 10 in the through groove 7. The rubber inclined blocks 10 move towards both sides of the through groove 7 as the copper busbars 3 are pressed against them, thus allowing the rubber inclined blocks 10 to move... The limiting plate 9 compresses the spring 8, causing the spring 8 to deform and generate relative elastic force. The spring 8 drives the rubber inclined block 10 to stick tightly to both sides of the copper busbar 3 through the elastic force, completing the sealing treatment at the opening of the through groove 7. When dust begins to accumulate on the surface of the heat dissipation mesh 11 after long-term use of the busbar trunk body 1, the motor 13 is started. The motor 13 drives the threaded rod 14 to rotate through the output shaft, so that the threaded rod 14 can drive the movable plate 15 to slide between the mounting plates 12, thereby allowing the movable plate 15 to drive the cleaning brush 16 to clean the surface of the heat dissipation mesh 11 and prevent dust from clogging the heat dissipation mesh 11.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
