The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation on the present application.

[0016] Please refer to Figure 1 andFigure 2 The embodiment provides a transformer with a lightning protection assembly, which comprises a transformer body 10, a telescopic protection pipe 20, a first driving assembly 30, a second driving assembly 40 and a lightning rod 50, the lightning rod 50 is movably arranged on the side of the transformer body 10, the lightning rod 50 is grounded through a grounding wire (not shown in the figure), the telescopic protection pipe 20 is movably sleeved on the outside of the lightning rod 50, the first driving assembly 30 and the second driving assembly 40 are installed on the side wall of the transformer body 10, when the lightning rod 50 needs to play a role, the second driving assembly 40 drives the telescopic protection pipe 20 to shorten, so that the telescopic protection pipe 20 is removed from the outside of the lightning rod 50, then the first driving assembly 30 drives the lightning rod 50 to rotate, so that the lightning rod 50 vertically extends above the transformer body 10.

[0017] When the lightning rod 50 does not need to play a lightning protection role, the lightning rod 50 is accommodated in the side position of the transformer body 10 and remains horizontally distributed, the telescopic protection pipe 20 is sleeved on the outside of the lightning rod 50, the lightning rod 50 is protected, the lightning rod 50 is prevented from being contaminated by dust and other foreign matters, the service life of the lightning rod 50 is prolonged, and when the lightning rod 50 is horizontally distributed, the wind resistance received by the lightning rod 50 can be reduced, so that the probability that the lightning rod 50 is blown by strong wind and then loosened and bent is reduced, and the use effect of the lightning rod 50 is improved; when the lightning rod 50 needs to play a lightning protection role, the second driving assembly 40 drives the telescopic protection pipe 20 to shorten, so that the telescopic protection pipe 20 is removed from the outside of the lightning rod 50, so as to expose the lightning rod 50, then the first driving assembly 30 drives the lightning rod 50 to rotate, so that the lightning rod 50 vertically extends above the transformer body 10, and then plays a lightning protection role.

[0018] Please refer to Figure 1 and Figure 2 In one embodiment, the first driving assembly 30 comprises a first incomplete gear 301, a support plate 302, a second incomplete gear 303 and a motor 304, the support plate 302 is fixedly arranged on the side wall of the transformer body 10, the motor 304 is fixedly installed on one side of the support plate 302, the second incomplete gear 303 is fixedly arranged on the output shaft of the motor 304, the first incomplete gear 301 is rotatably arranged on the side wall of the support plate 302 and can be engaged with the second incomplete gear 303, and the lightning rod 50 is fixedly arranged on the circumferential side wall of the first incomplete gear 301.

[0019] When the lightning rod 50 needs to play the role of lightning protection, the motor 304 is started, the output shaft of the motor 304 drives the second incomplete gear 303 to rotate, at this time the second drive assembly 40 drives the telescopic protective pipe 20 to shorten so that the telescopic protective pipe 20 is removed from the outside of the lightning rod 50, when the telescopic protective pipe 20 is removed from the outside of the lightning rod 50, the second incomplete gear 303 is engaged with the first incomplete gear 301, thereby driving the first incomplete gear 301 to rotate, when the first incomplete gear 301 rotates, the lightning rod 50 is rotated, so that the horizontally distributed lightning rod 50 is rotated to a vertical state, thereby extending above the transformer body 10, thereby playing the role of lightning protection.

[0020] Please refer to Figure 1 , Figure 2 and Figure 4 , in an embodiment, the telescopic protective pipe 20 comprises a telescopic pipe 201, a fixed seat 202 and a sliding seat 204, the fixed seat 202 is fixedly arranged on the side wall of the transformer body 10, the sliding seat 204 is slidably arranged on the side wall of the transformer body 10, the sliding seat 204 is oppositely distributed with the fixed seat 202, one end of the telescopic pipe 201 is connected with the fixed seat 202, and the other end is connected with the sliding seat 204, a through hole is formed in the sliding seat 204, which can allow the lightning rod 50 to extend into the inside of the telescopic pipe 201.

[0021] When the lightning rod 50 does not need to play the role of lightning protection, the sliding seat 204 is away from the fixed seat 202, the end of the lightning rod 50 away from the first incomplete gear 301 extends from the through hole to the inside of the telescopic pipe 201, and the lightning rod 50 is covered by the telescopic pipe 201, thereby achieving the protection of the lightning rod 50; when the lightning rod 50 needs to play the role of lightning protection, the second drive assembly 40 drives the sliding seat 204 to slide along the side wall of the transformer body 10 towards the fixed seat 202, the telescopic pipe 201 is compressed and shortened, after the sliding seat 204 moves away from the end of the lightning rod 50, the second incomplete gear 303 is engaged with the first incomplete gear 301, thereby driving the lightning rod 50 to rotate, so that the lightning rod 50 extends vertically above the transformer body 10, thereby playing the role of lightning protection.

[0022] Please refer to Figure 1 and Figure 3 , in an embodiment, a guide wheel 102 is rotatably arranged on the side wall of the transformer body 10, the second drive assembly 40 comprises a reel 401 and a pull rope 402, the reel 401 is fixedly arranged on the output shaft of the motor 304, one end of the pull rope 402 is connected with the reel 401, and the other end passes through the guide wheel 102 and is connected with the sliding seat 204.

[0023] While the motor 304 drives the second incomplete gear 303 to rotate through its output shaft, the output shaft of the motor 304 can also drive the reel 401 to rotate. When the reel 401 rotates, it reels the pull rope 402. When the pull rope 402 reels, it pulls the sliding seat 204 so that the sliding seat 204 slides along the side wall of the transformer body 10 and approaches the fixed seat 202. When the sliding seat 204 slides, it drives the telescopic tube 201 to shorten until the lightning rod 50 is exposed as a whole. When the lightning rod 50 is exposed as a whole, the rotating second incomplete gear 303 engages with the first incomplete gear 301, thereby driving the lightning rod 50 to rotate, so that the lightning rod 50 extends vertically above the transformer body 10.

[0024] See also Figure 1 In one embodiment, a guide rail 101 is fixedly provided on the side wall of the transformer body 10 , and the sliding seat 204 is in sliding cooperation with the guide rail 101 .

[0025] When the pull rope 402 pulls the sliding seat 204 , the sliding seat 204 slides along the guide rail 101 and approaches the fixed seat 204 , thereby driving the telescopic tube 201 to shorten.

[0026] See also Figure 1 as well as Figure 3 In one embodiment, the sliding seat 204 is connected to the fixed seat 202 via an elastic member 203 , and the elastic member 203 is used to provide elastic support for the sliding seat 204 .

[0027] When the motor 304 rotates and drives the reel 401 to rotate to reel the pull rope 402, the pull rope 402 pulls the sliding seat 204 so that the sliding seat 204 is close to the fixed seat 202. At this time, the elastic member 203 is gradually compressed by the force; when the lightning rod 50 plays its lightning protection role, the motor 304 drives the second incomplete gear 303 and the reel 401 to rotate in the opposite direction. When the second incomplete gear 303 rotates in the opposite direction, it meshes with the first incomplete gear 301 in the opposite direction and drives the first incomplete gear 301 to rotate in the opposite direction, thereby driving the lightning rod 50 to rotate in the opposite direction. When the reel 401 rotates in the opposite direction, the pull rope 402 is unwound. The elastic member 203 pushes the sliding seat 204 so that the sliding seat 204 moves away from the fixed seat 202. The sliding seat 204 pulls the telescopic tube 201 so that the telescopic tube 201 extends. When the lightning rod 50 rotates to the horizontal position again, the second incomplete gear 303 disengages from the first incomplete gear 301. As the reel 401 continues to reverse, the elastic member 203 continues to push the sliding seat 204 away from the fixed seat 202. The sliding seat 204 is re-sheathed on the outside of the lightning rod 50 and moves along the outside of the lightning rod 50, thereby pulling the telescopic tube 201 so that the telescopic tube 201 is re-sheathed on the outside of the lightning rod 50 to protect the lightning rod 50 again.

[0028] In one embodiment, the elastic member 203 can be a spring or a metal spring, which is not limited here.

[0029] In one embodiment, the telescopic tube 201 can be composed of a rubber bellows or a plurality of tube bodies connected in sequence, which is not limited here.

[0030] Please refer to Figure 4 In one embodiment, the flexible cleaning ring 205 is further arranged on the inner wall of the through hole.

[0031] When the motor 304 drives the reel 401 to reverse, the elastic member 203 pushes the sliding seat 204 to move along the outer part of the lightning rod 50, and the flexible cleaning ring 205 can act on the outer wall of the lightning rod 50, thereby pushing away the rainwater and dust and other sundries attached to the surface of the lightning rod 50, so as to clean the rainwater and dust and other sundries.

[0032] In one embodiment, the flexible cleaning ring 205 can be a rubber ring or a silica gel ring, which is not limited here.

[0033] In the embodiment of the application, when the lightning rod 50 does not need to play a lightning protection role, the lightning rod 50 is stored in the side position of the transformer body 10 and is horizontally distributed, and the telescopic protection tube 20 is connected to the outer part of the lightning rod 50, so as to protect the lightning rod 50 and prevent the lightning rod 50 from being contaminated by dust and other sundries, thereby improving the service life of the lightning rod 50, and the horizontally distributed lightning rod 50 can also reduce the wind resistance, thereby reducing the probability of the lightning rod 50 being blown by strong wind and then being loosened and bent, so as to improve the use effect of the lightning rod 50; when the lightning rod 50 needs to play a lightning protection role, the second driving assembly 40 drives the telescopic protection tube 20 to be shortened, so that the telescopic protection tube 20 is removed from the outer part of the lightning rod 50, so as to expose the lightning rod 50, and then the first driving assembly 30 drives the lightning rod 50 to rotate, so that the lightning rod 50 is vertically extended to the upper part of the transformer body 10, thereby playing a lightning protection role; compared with the prior art, when the lightning rod 50 does not need to play a lightning protection role, the lightning rod 50 can be stored and protected, and the influence of strong wind on the lightning rod 50 is reduced, thereby prolonging the service life of the lightning rod 50.
