The shunt equipment is used for connecting the shunt line 1 and achieving the purpose of shunting and guiding the current.

[0030] When the application is triggered, the on-off control of the electromagnet 26 connected to the surface of the control box 25 is realized through a remote controller, so that the electromagnet 26 is powered on; at this time, the unlocking process of the locking assembly 5 can be automatically triggered, so that the front end of the clamping mechanism 3 part can lose the pulling force generated by the locking assembly 5, and then the entire clamping mechanism 3 is pushed under the left and right spring inside the closing mechanism 4, so that the clamping plate part at the end of the clamping mechanism 3 can be close to each other and generate a clamping action, so that the first clamping plate 9 and the second clamping plate 10 are clamped on the surface of the shunt line 1 respectively; after the clamping contact is completed, enough pushing force is always applied to the clamping mechanism 3 through the rear spring mechanism; after the two shunt equipment are connected with the shunt line 1 through the above process, the current shunting process is completed.

[0032] Specifically, in the clamping mechanism 3, the shaft in the middle and the rotating sleeve 8 on the surface of the shaft are supported by the support frame 33, so that the clamping plates and the rotating arm 12 on both sides of the rotating sleeve 8 can rotate by relying on the rotating sleeve 8, and the inner side of the rotating arm 12 is provided with an abutting plate 18. Therefore, by pushing the abutting plate 18 through the two groups of spring structures in the subsequent sealing mechanism 4, a pushing force can be applied to the end of the rotating arm 12, so that the rotating arm 12 starts to expand outward. This process can make the first clamping plate 9 and the second clamping plate 10 on the other side approach each other, and finally clamp the clamping groove 34 in the first clamping plate 9 and the second clamping plate 10 on the inner side on the shunt wire 1.

The surface of the abutting plate 18 is provided with the closing mechanism 4, the spring structure part on the inner side is shielded by the closing mechanism 4, the pulling of the clamping mechanism 3 is matched with the locking assembly 5, so that the spring is always in a good sealing state, the erosion of the spring structure part is slowed down, and the service life of the equipment is prolonged.

[0034] Specifically, when the closing mechanism 4 is connected and locked with the pull plate 15 on the clamping mechanism 3, the abutting plate 18 is close to the position where the control box 25 is located, and it is ensured that the end of the closing mechanism 4 can be matched with the surface of the abutting plate 18. Because the surface of the closing mechanism 4 is provided with a double sleeve structure, the inner sleeve 21 part can press and match the rubber ring part at the end of the inner sleeve 21 on the surface of the abutting plate 18 by the thrust of the second spring 22 at the rear end, at this time, the center first spring 19 part can be in a compressed state, and the side and both ends are completely closed.

[0036] Specifically, the locking assembly 5 part is used to adsorb the magnetic plate 29 below through the electromagnet 26 at the top, so as to trigger the upward movement of the lifting column 30 and the inclined plate 31 to achieve the unlocking purpose. In the locked state, the electromagnet 26 is not electrified, after the catch pin 16 is embedded into the inside of the groove 23 by pulling the pull plate 15, the catch pin 16 is abutted from the inclined surface of the inclined plate 31, so that the lifting column 30 moves upward, and finally the catch pin 16 is moved to the vertical surface on the other side of the inclined plate 31, the catch pin 16 is blocked by the lifting column 30, so as to achieve the state that the whole abutting plate 18 is pulled to be attached with the closing mechanism 4.
