Example Embodiment

[0015] like figure 1 , figure 2 As shown, the cable of the tower submersible pump and the cable of the anti-sea biological device are respectively led out from the junction box (11) of the lift pipe (10) arranged on the pile leg (12), and wound on the respective cable recovery device (16). When the submersible pump (14) needs to rise or fall in order to meet the different operating water depths of the platform, manually rotate the cable recovery device (16) to synchronize the lifting of the cable with the submersible pump. At this time, the connection between the recovery device (16) and the deck junction box The connecting cable (17) should be disconnected. When the submersible pump is lifted to the working depth of the platform, insert the locking pin (8) of the recovery device to fix the turntable (1), and finally connect the connection cable (17) between the recovery device (16) and the deck junction box, and the submersible pump is Can be put to work.

Abstract

The invention relates to an offshore platform tower type submersible pump cable take-up and release apparatus. Cables are respectively led out from a junction box (11) of a lifting pipe (10) arranged on pile legs (12), and wind around respective cable take-up devices (16). When a submersible pump (14) needs to ascend or descend to satisfy different operation water depths of a platform, the cable take-up devices (16) are manually rotated to enable the cables and the submersible pump to elevate in a synchronous manner, and at the moment, connection cables (17) between the take-up devices (16) and a deck junction box should be disconnected. When the submersible pump is elevated to the operation water depth of the platform, locking pins (8) of the take-up devices are inserted so that rotating discs (1) are fixed, finally the connection cables (17) between the take-up devices (16) and the deck junction box are connected, and the submersible pump can operate. According to the apparatus, the distortion of cables of the submersible pump and marine growth preventing cables is avoided, the service lifetime of the cables is prolonged, and the labor intensity is reduced.

Description

technical field [0001] The patent of the present invention relates to a cable retracting device for a tower-type submersible pump on an ocean platform, which is installed on an ocean platform and is mainly used for recovering or lowering the cables of the tower-type submersible pump and the cables of the anti-sea organism device when the platform is raised and lowered. . Background technique [0002] The existing tower type submersible pump cable retracting device is connected to the junction box on the deck because the cable is drawn out from the rotating shaft. The cable is long (usually 3-4 meters), and the cable will be twisted continuously during the rotation process. At this time, the cable needs to be artificially corrected. Over time the cable will shorten its service life due to twisting. In addition, because the junction box needs to be fixed in a suitable position on the deck, the cables of the submersible pump are messy on the deck, which brings inconvenience t...
