Description

Technical Field

[0001] This utility model relates to the field of transformer heat sink cleaning technology, specifically a dustproof cleaning auxiliary brush holder for transformer heat sinks. Background Technology

[0002] Transformer heat sinks are an important component used to increase the surface area of ​​a transformer for heat dissipation. Their working principle is primarily based on the physical principles of heat conduction and convection. The main function of the heat sink is to increase the transformer's surface area. Heat generated inside the transformer is conducted to the outside through the windings and core, and then released through the heat sink. The large-area design of the heat sink helps to increase the surface area for heat transfer, thus improving heat dissipation efficiency.

[0003] Patent document CN115346767A discloses a heat sink fixing fixture for a transformer radiator. A locking assembly is used to install and fix the radiator. The locking assembly includes two sets of double-ended screws and corresponding scissor-fork components. The two sets of double-ended screws are connected by a smooth rod. Specifically, the scissor-fork components are deformed by rotating the double-ended screws. First, the scissor-fork components are closed to facilitate insertion into the mounting holes of the radiator. Then, the scissor-fork components are unfolded and locked by reverse compression. This design requires only the cooperation of the double-ended screws and the scissor-fork components, without any other unnecessary structures. Manually turning the retaining ring drives the connecting part and pulley in the transmission assembly to rotate. This pulley, via a belt, drives all other pulleys to rotate synchronously. A locking assembly is mounted below each pulley, thus synchronously controlling the operation of each locking assembly.

[0004] The above solution lacks a mechanism for cleaning the heat sink in actual use, which leads to a large amount of dust accumulating on the surface of the heat sink after long-term use. The dust cover can easily cause heat accumulation, which seriously affects the heat dissipation effect of the heat sink on the transformer. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dust-proof cleaning auxiliary brush holder for transformer heat sinks includes a transformer body and a cleaning frame assembly. Heat sink bodies are provided on both the front and back of the transformer body. The cleaning rack assembly includes a mounting vertical plate and two symmetrical horizontal beams. The two horizontal beams are fixedly installed at the upper and lower ends of the mounting vertical plate, and connecting frames are provided at both ends of the two horizontal beams. The surface of the connecting frames is provided with a number of equally spaced screw holes, and the inner wall of the screw holes is threaded with mounting bolts. A spacing adjustment mechanism is provided between the connecting frames and the horizontal beams. The mounting plate has a mounting groove on its back. A motor is fixedly mounted on the upper surface of the upper beam. The output shaft of the motor extends into the mounting groove and is fixedly connected to a reciprocating screw. A moving block is provided on the surface of the reciprocating screw. A cleaning plate is fixedly connected to the back of the moving block. The back of the cleaning plate is provided with bristles corresponding to the position of the heat sink body.

[0006] In a preferred embodiment, a guide slider is provided on the front of the moving block, and a guide groove is provided on the inner front wall of the mounting groove for the guide slider to slide.

[0007] Guided by the guide slider, the moving block can drive the cleaning plate to move up and down in a directional manner through the rotation of the reciprocating screw.

[0008] In a preferred embodiment, a horizontal pipe is fixedly installed on the surface of the above-mentioned crossbeam by a bracket. An air outlet is embedded in the lower surface of the horizontal pipe. An external pipe is provided at the right end of the horizontal pipe, and the end of the external pipe away from the horizontal pipe is connected to an external fan.

[0009] In a preferred embodiment, the number of air outlets is several, and the several air outlets are equidistantly arranged on the lower surface of the horizontal tube.

[0010] In a preferred embodiment, the lower crossbeam has through-holes at both ends with assembly slots. Two symmetrical mounting plates are fixedly installed inside the assembly slots. Rotation openings are formed on the surfaces of the two mounting plates. A bidirectional threaded rod is rotatably connected to the inner wall of the rotation opening. A transmission opening extending through the assembly slot is formed on the front of the lower crossbeam. An operating rod is rotatably connected to the inner wall of the transmission opening. A bevel gear is fixedly connected to the end of the operating rod inside the assembly slot and the surface of the bidirectional threaded rod. Two symmetrical threaded cylinders are threaded to both ends of the bidirectional threaded rod. The ends of the two threaded cylinders away from the bidirectional threaded rod are fixedly connected to the surfaces of two connecting frames, respectively.

[0011] In a preferred embodiment, both ends of the upper crossbeam are provided with limit grooves, and the opposite surfaces of the two connecting frames are fixedly connected with limit rods that slide inside the limit grooves. The front of the upper crossbeam is provided with two sliding strip openings that pass through the two limit grooves respectively. The end surface of the limit rod located inside the limit groove is fixedly connected to a screw through the sliding strip opening, and a fixing nut is threaded onto the surface of the screw.

[0012] By using a limit rod and a fixing nut, the threaded cylinder can drive the connecting frame to move in a specific direction through the rotation of the bidirectional threaded rod.

[0013] As can be seen from the above, the auxiliary brush holder for dust prevention and cleaning of transformer heat sinks provided by this utility model has the following technical effects.

[0014] 1. During use, the motor drives the reciprocating screw to rotate. Under the guidance of the guide slider, the moving block can drive the cleaning plate to move up and down through the rotation of the reciprocating screw. The movement of the cleaning plate drives the bristles to sweep the surface of the heat sink body to remove the dust covering it. At the same time, the external fan blows air into the horizontal pipe through the external pipe and blows it out through several air outlets. Combined with the sweeping of the bristles, the cleaning effect on the heat sink body can be further improved. 2. Loosen the fixing nut on the surface of the screw. Without the restriction of the fixing nut, rotate the operating lever to drive the double-sided threaded rod to rotate through the bevel gear. Under the guidance of the limit rod, the two threaded cylinders can drive the connecting brackets on both sides to move closer or in opposite directions through the rotation of the double-sided threaded rod. The installation distance of the two connecting brackets can be adjusted according to the width specifications of different transformers, which improves the adaptability of the cleaning brush frame.
