Abstract
The invention relates to offshore well auxiliary power facilities, in particular to zinc alloy union spring type offshore well auxiliary power equipment. Each platform hinge on the periphery of an operation platform is connected to one end of a corresponding union spring shock absorber, the other end of each union spring shock absorber is connected with a corresponding fixing support, and an inclined angle is formed between each union spring shock absorber and the operation platform to guarantee stability and fixation of the operation platform. Each union spring shock absorber adopts union connection combined with double-spring combination for shock absorption, and each union spring shock absorber is capable of bearing tension or pressure at the same time to guarantee that the operation platform is capable of withstanding wave impacts in any directions. A communication part is arranged between a motor shell and each of a front end cover and a rear end cover to guarantee that dependency of sealing of cooling water channels onto close attachment of end faces is avoided. Since the operation platform integrates an end cover water drawing motor and the union spring shock absorbers, the problems of shock absorption of integral well facilities and proneness to damages of power source motors are solved at the same time, and extraordinary effects are achieved.
