Submersible pump for solar well

Abstract

The invention discloses a solar immersible pump for wells. The solar immersible pump comprises a pump head, a motor, a water outlet pipe and a solar panel; the motor is installed at one end of the pump head and drives the pump head to do work, the water outlet pipe is connected with the pump head and an external water demand portion, and the solar panel is arranged on the ground and connected withthe motor through a cable; a guiding frame is fixed to the top of the pump head, the immersible pump further comprises a guide rod assembly, the guide rod assembly is arranged on the well wall, and the guiding frame vertically slides along the guide rod assembly. The immersible pump is inverted in a well, the pump head is arranged at the upper portion, and the motor is arranged at the lower portion. The pump head comprises several pump bodies, impellers, pump shafts, a cover assembly and a water outlet base, wherein the pump bodies, the impellers and the pump shafts have the same number. Theimpellers sleeve the pump shafts and are in transmission connection with the pump shafts, the impellers and the pump shafts are all located in the pump bodies, the axes of the pump shafts coincide with the center lines of the pump bodies, each pump shaft comprises a square head and a positioning section, each square head and the corresponding positioning section are located at the two ends of thecorresponding pump shaft respectively, and a square inner hole is formed in the portion, facing outwards, of the center of each positioning section in the axial direction; the pump bodies, the impellers and the pump shafts are stacked in sequence in the axial direction.

Description

technical field [0001] The invention relates to the field of submersible pumps, in particular to a submersible pump for solar wells. Background technique [0002] Water for agricultural irrigation or domestic water in remote areas is often obtained from wells, and well water pumps are needed. If the pumps are installed on the ground, water needs to be filled when the pumps start, which is a bit troublesome, so they are generally in the form of submersible pumps. [0003] Existing well water pumps only use conventional general-purpose submersible pumps, but in many usage environments, long-distance power transmission is required, and the laying of lines is troublesome, and the installation of submersible pumps is inconvenient. If the steel rope is directly hung down, it will shake during operation. Obviously, it is troublesome to install parts such as mounting bases at the bottom of the well, and the installation height cannot be adjusted. [0004] When the submersible pump ...

AI Technical Summary

Problems solved by technology

[0003] Existing well water pumps only use conventional general-purpose submersible pumps, but in many usage environments, long-distance power transmission is required, and the laying of lines is troublesome, and the installation of submersible pumps is inconvenient. If the steel rope is directly hung down, it will shake during operation. Obviously, it is troublesome to install parts such as mounting bases at the bottom of the well, and the installation height cannot be adjusted

[0004] When the submersible pump is used, the motor burnout caused by the drop of the water level and the exposure of the motor also occurs from time to time. If the working water level and the warning water level are judged by some liquid level switches, it is also necessary to set up a complicated control cabinet.

[0005] The delivery of well water to farther places requires a higher head, and the adjustment range by changing the motor speed is small, and the applicable scenarios are limited
