[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a fixing structure for a current acquisition device, including a fixing frame 1, a heat dissipation frame 2 fixedly connected to the side wall of the fixing frame 1, an adjustment frame 16 fixedly connected to the side wall of the fixing frame 1, bolts provided on the side wall of the fixing frame 1 to fix the fixing frame 1 at the required installation position, thereby improving the stability of the fixing frame 1 during the fixing process, a rotating rod 3 rotatably connected to the side wall of the fixing frame 1, a connecting frame 4 fixedly connected to the outer surface of the rotating rod 3, the rotation of the rotating rod 3 driving the connecting frame 4 to rotate inside the adjustment frame 16, a positioning mechanism 5 provided inside the connecting frame 4, and an adjustment rod 6 fixedly connected to the end of the rotating rod 3, the adjustment rod 6 rotatably connected inside the fixing frame 1, the rotation of the rotating rod 3 driving the adjustment rod 6 to rotate inside the fixing frame 1;

[0034] Furthermore, a connecting rod 7 is hinged to the side wall of the adjusting rod 6, and a limiting groove is provided on the side wall of the fixed frame 1. A moving rod is provided on the side wall of the connecting rod 7, which passes through and is slidably connected inside the limiting groove. The adjusting rod 6 is used to drive the connecting rod 7 to move during the rotation process. Through the setting of the limiting groove and the moving rod, the connecting rod 7 can move stably inside the fixed frame 1 during the movement process. A moving plate 8 is hinged to the side wall of the connecting rod 7, and a clamping plate 10 is elastically connected to the side wall of the moving plate 8 through a clamping spring 9. A current collector body 15 is provided on the side wall of the fixed frame 1. The clamping plate 10 clamps the side wall of the current collector body 15. When the clamping plate 10 is pushed, it squeezes the clamping spring 9, causing the clamping spring 9 to deform. When resetting, the rebound of the clamping spring 9 drives the clamping plate 10 to slide and reset.

[0035] Furthermore, the side walls of the movable plate 8 and the clamping plate 10 are slidably connected to the side wall of the fixed frame 1. During the movement, the connecting rod 7 drives the movable plate 8 and the clamping plate 10 to move on the side wall of the fixed frame 1. A servo motor 11 is fixedly connected inside the heat dissipation frame 2. A fan 12 is fixedly connected to the output end of the servo motor 11. The operation of the servo motor 11 drives the fan 12 to rotate. The wind force generated by the fan 12 during rotation dissipates heat from the current collector body 15. A rotating block 13 is fixedly connected to the side wall of the fan 12. The rotating fan 12 drives the rotating block 13 to rotate. A tapping component 14 is provided on the side wall of the heat dissipation frame 2.

[0036] Reference Figures 3-5 The positioning mechanism 5 includes a positioning plate 51, which is slidably connected inside the connecting frame 4. The connecting frame 4 has a connecting groove inside, which allows the positioning plate 51 to be slidably connected inside the connecting frame 4. A push rod is provided on the side wall of the positioning plate 51, which drives the positioning plate 51 to slide. One side of the positioning plate 51 is elastically connected to the inner side wall of the connecting frame 4 through a positioning spring 53. During the sliding process, the positioning plate 51 compresses the positioning spring 53, causing the positioning spring 53 to deform. When resetting, the rebound of the positioning spring 53 drives the positioning plate 51 to slide and reset. A positioning block 52 is fixedly connected to the other side of the positioning plate 51. The side wall of the adjusting frame 16 has multiple positioning holes of equal size and arranged in a ring. The positioning block 52 passes through the connecting frame 4 and is inserted into the positioning hole. The positioning block 52 is used to ensure that after the rotating rod 3 rotates to the appropriate position, it is inserted into the positioning hole, thereby improving the stability of the rotating rod 3 during the fixing process.

[0037] Reference Figures 4-6 The tapping assembly 14 includes a sieve 141, which is slidably connected inside the heat sink frame 2. The sieve 141 filters the airflow from the fan 12, preventing impurities from entering the current collector body 15 and damaging internal components. A fixing groove is provided on the side wall of the heat sink frame 2, and a slider adapted to the size of the fixing groove is provided on the side wall of the sieve 141. The fixing groove and slider allow the sieve 141 to slide within the heat sink frame 2. The side wall of the sieve 141 is connected to the inner side of the heat sink frame 2 by a return spring 142. The screen 141 is elastically connected to the wall. When the screen 141 is pushed, it compresses the return spring 142, causing the return spring 142 to deform. During reset, the rebound of the return spring 142 drives the screen 141 to slide and reset. The side wall of the screen 141 is fixedly connected to a protrusion 143. Both sides of the rotating block 13 and the protrusion 143 are arc-shaped. The side wall of the rotating block 13 contacts the side wall of the protrusion 143. The rotating block 13 pushes the protrusion 143, thereby causing the protrusion 143 to slide inside the heat sink frame 2.

[0038] Working principle: In use, the current collector body 15 that needs to be fixed is placed on the side wall of the fixed frame 1. Then, the positioning plate 51 is pushed and the positioning spring 53 is squeezed to drive the positioning block 52 into the interior of the connecting frame 4. The rotating rod 3 is rotated to drive the adjusting rod 6 to rotate. The rotation of the adjusting rod 6 drives the connecting rod 7 and the moving plate 8 to move, thereby driving the clamping spring 9 and the clamping plate 10 to stably clamp the side wall of the current collector body 15. After clamping, the push on the positioning plate 51 is released. The rebound of the positioning spring 53 drives the positioning block 52 to rebound and insert into the interior of the adjusting frame 16, which has a stabilizing and limiting effect on the rotating rod 3 and improves the stability of the clamping plate 10 in the clamping process of the current collector body 15. Then, the fixed frame 1 is fixed in the distribution cabinet with bolts for use.

[0039] When the current collector body 15 accumulates heat over a long period of time, the servo motor 11 drives the fan 12 to rotate, which in turn cools the current collector body 15. When the screen 141 becomes clogged due to prolonged heat dissipation, the rotation of the fan 12 drives the rotating block 13 to rotate, which in turn pushes the protrusion 143. After being pushed, the protrusion 143 compresses the reset spring 142, causing the screen 141 to slide inside the heat dissipation frame 2. When the rotating block 13 stops pushing the protrusion 143, the return of the reset spring 142 causes the screen 141 to spring back and reset, thus vibrating the impurities clogging the screen 141 to the outside of the heat dissipation frame 2, improving the heat dissipation efficiency of the fan 12, and thereby improving the safety of the current collector body 15 during use.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
