[0002] A power receiving transformer is a device in a power system that converts high-voltage electrical energy into low-voltage electrical energy. It is mainly installed at the entrance of the user's power distribution system to connect the power grid and the user's power distribution system. If a power receiving transformer is not cleaned for a long time, a large amount of dust will accumulate on its heat sink, resulting in insufficient heat dissipation and increased energy consumption due to transformer losses. Therefore, it is necessary to use a power receiving transformer heat sink cleaning brush to clean the heat sink. However, the currently used power receiving transformer heat sink cleaning brush is manually held by hand to clean the heat sink, which is difficult to operate. Utility Model Content

A reciprocating screw 302 is installed on the first bearing 304. A first motor 3 is fixedly installed on the upper surface of the mounting frame 2. The rotating part of the first motor 3 is fixedly connected to the reciprocating screw 302. A first slider 303 is threadedly installed on the outer surface of the reciprocating screw 302. A cleaning brush 4 is fixedly installed on the rear surface of the first slider 303. A fixing structure 5 is provided inside the C-shaped mounting base 1. The cleaning brush is connected to an external power source. The first motor 3 and the second motor 501 are controlled by a PLC controller.

[0015] Specifically, the No. 1 motor 3, which is fixedly mounted on the upper surface of the mounting bracket 2, and the reciprocating lead screw 302, which is fixedly connected to the rotating part of the No. 1 motor 3, can be started by the PLC controller. The rotating part of the No. 1 motor 3 drives the reciprocating lead screw 302 to rotate on the No. 1 bearing 304, and the No. 1 slider 303, which is threaded on the outer surface of the reciprocating lead screw 302, slides up and down in the No. 1 slide groove 301, thereby moving the cleaning brush 4 up and down to clean the heat sink.

[0016] Participation Figure 2-4 As shown, the fixed structure 5 includes a second motor 501, a rectangular slide 502, a rectangular slider 503, a second bearing 504, a rotating rod 505, a rectangular groove 506, a first bevel gear 507, a second bevel gear 508, a third bearing 509, a bidirectional threaded rod 510, a fixed plate 511, and a silicone pad 512. The second motor 501 is fixedly installed on the upper surface of the C-type mounting base 1 near the other end. The rotating part of the second motor 501 is fixedly connected to the rotating rod 505. A rectangular groove 506 is opened inside the C-type mounting base 1.

[0017] Specifically, the second motor 501, which is fixedly installed on the upper surface of the C-type mounting base 1 near the other end, and the rotating rod 505, which is fixedly connected to the rotating part of the second motor 501, can be started by the PLC controller, so that the second motor 501 drives the rotating rod 505 to rotate.

[0018] Participation Figure 2-4As shown, a No. 2 bearing 504 is fixedly installed in the middle of the upper and lower surfaces of the rectangular groove 506. A rotating rod 505 is installed on the No. 2 bearing 504. A No. 2 bevel gear 508 is fixedly installed on the outer surface of the rotating rod 505 near the upper and lower ends. A rectangular slide groove 502 is opened on the upper and lower surfaces of the inner side of the C-type mounting base 1. A No. 3 bearing 509 is fixedly installed in the middle of the two ends of the rectangular slide groove 502. A double-threaded rod 510 is installed on the No. 3 bearing 509. A No. 2 bevel gear 508 is fixedly installed on the other end of the double-threaded rod 510. The No. 2 bevel gear 508 meshes with the No. 1 bevel gear 507.

[0019] Specifically, the second bevel gear 508, which is fixedly installed on the outer surface of the rotating rod 505 near both the upper and lower ends, can drive the first bevel gear 507, which is fixedly installed on the outer surface of the rotating rod 505 near both the upper and lower ends, to rotate when the rotating rod 505 rotates. Because the first bevel gear 507 meshes with the second bevel gear 508, it drives the bidirectional threaded rod 510 to rotate on the third bearing 509.

A silicone pad 512 is fixedly installed on the inner surface of the fixing plate 511.

[0021] Specifically, the rectangular sliders 503 installed near the two ends of the outer surface of the bidirectional threaded rod 510 and the rectangular sliders 503 fixedly installed in the middle of the upper and lower surfaces of the fixed plate 511 can slide in the rectangular groove 502 when the bidirectional threaded rod 510 rotates, thereby driving the two fixed plates 511 to move.

[0022] It should be noted that this utility model is a cleaning brush for the heat sink of a power receiving transformer. When cleaning the heat sink of a power receiving transformer is required, first, the C-type mounting base 1 is placed around the heat sink. Then, the PLC controller controls the start of motor 501, causing the rotating part of motor 501 to drive the rotating rod 505 to rotate on bearing 504. This drives the first bevel gear 507, which is fixedly mounted near the upper and lower ends of the outer surface of the rotating rod 505, to rotate. Because the first bevel gear 507 meshes with the second bevel gear 508, it drives the double... The threaded rod 510 rotates on the bearing 509, causing the rectangular slider 503, which is threaded on the outer surface of the bidirectional threaded rod 510, to slide in the rectangular groove 502. This causes the two fixed plates 511 to move towards the center. Then, the PLC controller controls the start of the motor 3, causing the rotating part of the motor 3 to drive the reciprocating screw 302 to rotate on the bearing 304. This causes the slider 303, which is threaded on the outer surface of the reciprocating screw 302, to slide up and down in the groove 301, thereby causing the cleaning brush 4 to move up and down to clean the heat sink.
