Hot water submersible pump is used for hot spring bathing, and can also be used for extracting underground water from deep well, and can also be used for river, reservoir, water channel and other water lifting engineering. It is mainly used for farmland irrigation and water for people and livestock in high mountain area, and can also be used for central air conditioning cooling, heat pump unit, cold pump unit, city, factory, railway, mine and construction site drainage.

[0003] The existing submersible pump often needs lifting device to assist operation when using, the depth of the submersible pump is adjusted by using the lifting device, and the submersible pump is conveniently lifted out of the water surface for maintenance. However, the applicant finds that when the submersible pump is actually lifted, 1, the lifting chain is generally connected to the lifting lug of the submersible pump during lifting of the submersible pump, but if the lifting lug is worn or the connection between the lifting lug and the submersible pump is corroded, the submersible pump is prone to falling off, and the safety protection of the submersible pump needs to be improved. 2, in order to prevent the submersible pump from being damaged by collision, the existing technology adopts a protection frame to protect the submersible pump, but the protection frame lacks a buffer device when colliding in actual use, which causes large impact vibration, thereby affecting the submersible pump, and the protection frame is also prone to deformation and damage. In order to solve the above problems, a lifting type high protection submersible pump is provided. UTILITY MODEL CONTENTS
