Problems solved by technology

[0002] In the past, when the submersible pump was draining, high-pressure water was discharged from the outlet pipe of the coupling base. The high pressure of the discharged high-pressure water would cause a gap between the coupling surface of the coupling base and the coupling surface of the outlet flange of the submersible pump, which would cause Part of the water discharged by the submersible pump flows back into the drainage pool from such a gap, that is, the water discharged by the submersible pump cannot be completely discharged from the outlet pipe of the coupling base, resulting in water loss. In order to solve this problem of water loss, it is necessary to invent A device for preventing the gap generated between the above-mentioned coupling surfaces

Abstract

The invention provides an auto-coupling and auto-locking device of a high lift diving pump and relates to a drainage device of the a diving pump. A high pressure liquid transport pipe (1) is connected with a coupling base (2) and a hydraulic cylinder (9); a coupling surface (33) of a pump splint (3) is pressed on a coupling surface (28) of a pump splint of the coupling base (2), the pump splint (3) is connected to a diving pump (7) via a bolt (6); a guide rail (4) is inserted in a guide rail pin (5) which is connected with a guide hole (29) of the coupling base (2); floor (11) on which the hydraulic cylinder (9) is arranged on is mounted on a foundation via holding down bolts (10); a steel axle (19) is provided with a piston (17) and a spring seat (15) and is sleeved with spring (14). One end of the steel axle (19) is pulled through an axle hole (42) of the steel axle (19) and supports an outlet flange of the diving pump (7). The device can avoid water loss of the coupling surface.
