Description

Technical Field

[0001] The present invention relates to the technical field of electric power protection, and in particular to an electric power detection and protection device. Background Art

[0002] In the power system, the pull rod is a commonly used protective tool for operating high-voltage disconnectors, namely "knife switches". The traditional pull rod usually includes an insulating rod and a hook head fixed at one end of the insulating rod. Since different types and specifications of knife switches require different hook heads, the pull rods are mostly designed to be riveted directly to the insulating rod. The riveted form is difficult to disassemble, so power inspectors need to carry multiple pull rods with different hook heads. However, multiple pull rods are not convenient for power inspectors to move and carry. Therefore, in order to solve the above problems, the present invention proposes a new type of power detection and protection device. Summary of the invention

[0003] The purpose of the present invention is to provide a power detection and protection device to solve the problems raised in the above background technology.

[0006] A locking assembly, wherein the locking assembly is arranged on the side of the positioning sleeve, and the locking assembly is used to lock the insertion point of the hook head and the positioning sleeve. The locking assembly includes a locking sleeve arranged on the side of the positioning sleeve, and an insertion rod is inserted and connected inside the locking sleeve. The ends of the insertion rod are inserted and connected to the side of the positioning sleeve and the side of the hook head in sequence, and the inner cavity of the locking sleeve is provided with a rebound portion for resetting and inserting the insertion rod.

[0007] Preferably, the rebound portion includes a pressure ring and a compression spring sleeved on the outside of the insertion rod, and the pressure ring is arranged at one end of the compression spring close to the positioning sleeve.

[0008] Preferably, a limiting plug block is provided on the side of the hook head, the bottom end of the limiting plug block is inserted and connected to the top of the positioning sleeve, and the limiting plug block is used to prevent the hook head from rotating.

[0009] Preferably, a locking hole for inserting the rod is provided at the bottom of the hook head, and an expansion bell mouth is provided on the inner wall of one end of the locking hole, and the expansion bell mouth is used for guiding the insertion of the rod.

[0010] Preferably, the connecting portion includes a connecting thread head arranged at the bottom end of the fixing rod, the bottom end of the connecting thread head is threadedly inserted and connected with a connecting thread sleeve, and the connecting thread sleeve is arranged at one end of the holding rod.

[0011] Preferably, the other end of the gripping rod is sleeved with a rubber sleeve, and the rubber sleeve is used for insulation of the palm grip.

[0012] Preferably, a plurality of friction grooves are provided on the outer side of the rubber sleeve, and the friction grooves are used to increase the friction between the palm and the rubber sleeve.

[0013] Technical effects and advantages of the present invention:

[0014] The present invention provides a locking assembly at the connection between the hook head and the positioning sleeve. The power inspection personnel pulls the insertion rod in the locking sleeve, and the moving insertion rod squeezes the rebound part, so that the insertion rod is separated from the insertion part with the hook head, thereby replacing the hook head. Compared with the form in which the hook head is directly riveted to the insulating rod, this hook head fixing form enables the power inspection personnel to replace the appropriate hook head according to the type of switch knife, avoiding carrying multiple types of switch pulling rods.
