Since the transmission gear 450 provided between the adjacent first and second pressing bars 430 and 440 is one, the moving directions of the adjacent first and second pressing bars 430 and 440 are opposite.
The driving rod 420 pushes the first pressing rod 430 toward the cable, and then all of the first pressing rod 430 moves toward the cable, and all of the second pressing rod 440 moves toward a side away from the cable. In this way, the first extrusion rod 430 extrudes the rubber ring 200, the second extrusion rod 440 pulls the rubber ring 200, and the first extrusion rod 430 and the second extrusion rod 440 are alternately arranged in sequence, so that the rubber ring 200 can be in a wrinkled state and smoothly attached to the surface of the cable, the rubber ring 200 is tightened to the surface of the cable under the action of the extrusion assembly 400, the rubber ring is fully attached to the surface of the cable, and sealing is achieved, as shown in fig. 5.
In addition, the end of the first extrusion rod 430 has the expanded diameter section 431, so that the folded portion of the rubber ring 200 can be closely attached to each other, thereby improving the sealing effect.
The self-locking between the adjustment sleeve 410 and the driving rod 420 can be realized very conveniently.
The embodiment also provides an installation and debugging method for the electric equipment installation auxiliary device of the offshore wind power booster station, which comprises the following steps:
the cable is threaded into the outer tube 100 from an end of the outer tube 100 remote from the connection portion 110 and is threaded out from an end of the connection portion 110 after passing through the rubber ring 200.
After the cable is connected and the cable joint explosion-proof box 2000 is mounted, the outer tube 100 is hermetically connected to the end of the cable joint explosion-proof box 2000 through the connection portion 110.
The rubber ring 200 is extruded by the extrusion assembly 400, so that the rubber ring 200 is attached to the outer part of the cable, and the sealing between the rubber ring 200 and the cable is realized.
In summary, the auxiliary device for installing the electrical equipment of the offshore wind power booster station provided by the embodiment of the invention can effectively improve the sealing effect of the cable connection part 110, reduce the damage and corrosion of the surrounding environment to the cable connection part 110, and effectively improve the safety of the cable connection part 110. The installation and debugging method provided by the embodiment of the invention can effectively improve the sealing effect of the cable connecting part 110, reduce the damage and corrosion of the surrounding environment to the cable connecting part 110 and effectively improve the safety of the cable connecting part 110.
