The invention discloses a submersible pump lifting and descending device for a hydrothermal geothermal well. The submersible pump lifting and descending device comprises a lifting assembly and a supporting assembly. The hoisting assembly is used for hoisting a submersible pump or a pump pipe and comprises a hoisting frame, a hoisting ring, a positioning rod, a positioning clamping block and a guide mechanism. The supporting assembly is used for supporting a submersible pump or a pump pipe and comprises a supporting bottom plate, a supporting vertical rod and a supporting semi-ring. Openings of the two supporting semi-rings are opposite, and the two supporting semi-rings can be supported below a submersible pump flange or a pump pipe flange plate, so that the pump pipe or the submersible pump is prevented from directly falling into a hydrothermal well. The upper portion of the lifting assembly is fixed to a lifting hook of the mobile truck crane, the lifting assembly and the lifting hook of the truck crane are only installed once, disassembly and assembly are not needed when pump pipes are connected every time, the pump lifting and descending time is shortened, and the personal safety of operators is guaranteed.

    本发明公开了一种水热型地热井提、下潜水泵装置,包括起吊组件和支撑组件;起吊组件用以吊装潜水泵或泵管,包括起吊架、吊环、定位杆、定位卡块和导向机构;支撑组件用以支撑潜水泵或泵管,包括支撑底板、支撑竖杆和支撑半环;两个支撑半环开口相对且二者能支撑在潜水泵法兰或泵管法兰盘下方,避免泵管或潜水泵直接掉落到水热井内。本发明起吊组件上部与流动式汽车吊的吊钩进行固定,只与汽车吊吊钩安装一次,不再随每次连接泵管进行拆装,加快了提、下泵时间且保障了作业人员的人身安全。
