Mechanical lifting device for mobile floor of swimming pool

摘要

A mechanical lifting device for a movable floor of a swimming pool, usually driven by a double acting hydraulic cylinder supplied by a water or low viscosity water fluid pressurizer. This immersible device has been developed in private or public swimming pools and Mediterranean therapeutic basins. The device can also be driven by a hydraulic motor, a cylinder, or an electromechanical actuator. The dlm-pmp device is suitable for immersion in the treated fresh water specially used for swimming pools and is operated with the same fluid or water hydraulic fluid, orThe biodegradable compounds are completely mixed to conform to the principle of nature protection. The unique feature of "dlm-pmp" device lies in its completely immersible mechanical design and innovative kinematics.Figure-7 shows that the upper part of a pool floor structure is supported by two tilting arms, and the other two tilting arms are supported on a gasket, As a result, the floor support beam (DL) between the surface and the bottom of the pool is allowed to move in a horizontal plane and be held in any intermediate fixed position by locking the drive. The dynamic motion of the device is realized by two sliding sliding sliding sliding sliding sliding sliding sliding sliding sliding sliding devices which slide on the floor support beam.Movement is achieved by closed-loop cable transmission between two crazy pulley couplings and a transmission actuator.
