Problems solved by technology

[0002] At present, there is a relatively serious water ingress problem in the PASS equipment mechanism box in the power grid, which affects the normal work and operation of power grid equipment, especially primary equipment such as circuit breakers and isolating switches, and has hidden dangers of equipment and system accidents
The problem of water ingress is mainly caused by two reasons: one is that the mechanism box is located on the edge of the PASS switch air chamber, which is not fully protected and is easily eroded by cold waves and rain; the other is that the operation and maintenance personnel sometimes open the cover of the mechanism box due to work needs Waterproof gasket seal damaged
Waterproof treatment has become a thorny problem that operation and maintenance personnel often encounter but it is difficult to find a good solution

Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing:

[0012] Such as figure 1 , 2 As shown, the present invention is composed of a lock body and a lock hook. The lock body is composed of a base (1), a pull plate (2) and a pull arm assembly. The pull plate and the base are hinged through the hinge shaft (3), and the pull arm assembly is hinged with the pull plate through the hinge shaft (4). The pull arm assembly is composed of two fixed pull arms (5) hinged at both ends of the pull plate and two movable pull arms (7) respectively sleeved on the fixed pull arms by two springs (6). The ends of the two movable pull arms are connected with A locking lever ⑻.

[0013] The base of the lock body is provided with a fixing bolt (9).

[0014] The lock hook is composed of a hook body ⑽ and a base ⑾, and the base is provided with a fixing bolt ⑿.

[0015] When in use, the lock body and the lock hook are respectively fixed on the box c...

Abstract

The invention relates to a mechanism case cover tightening lock for substation equipment. The mechanism case cover tightening lock is composed of a lock body and a lock hook, and is characterized in that the lock body is formed by connection of a base, a pull plate and a pull arm component, the pull plate is hinged to the base through a hinge shaft, and the pull arm component is hinged to the pull plate through a hinge shaft; the pull arm component is composed of two fixed pull arms hinged to two ends of the pull plate and two movable pull arms respectively sleeving the fixed pull arms through two springs, and a lock bar is connected to ends of the movable pull arms. A mechanism case cover can be fixed on a fixed plate through a hinged connection structure and effect of the springs, sealing performance of the mechanism case cover is enhanced, and the problem about water inflowing of a mechanism case is solved. The mechanism case cover tightening lock is simple in structure, convenient to mount and use and high in universality.
