Abstract

The invention discloses a small direct expansion type solar energy heating pump. The small direct expansion type solar energy heating pump comprises a heating steam engine. The heating steam engine comprises a housing. The housing is internally provided with a displacer piston and a power piston which are transversely arranged and connected with each other and a heating pipe and a cooling pipe are laid on the outside of the housing. The small direct expansion type solar energy heating pump further comprises a solar heat collection panel, a bearing and a working water tank. A heat transfer pipe of the solar heat collection panel is communicated with the heating pipe through a connecting pipe. The power piston of the heating steam engine is connected to the bearing through a connecting rod. A working piston of the working water tank is connected to the bearing through a connecting rod. A drain pipe and a pumping pipe are mounted at the bottom of the working water tank. The drain pipe is communicated with the cooling pipe. Heating space and cooling space are filled with an organic working medium of isopentane. The small direct expansion type solar energy heating pump pumps underground water by heating the organic working medium with solar energy to expand to drive the pistons to move to output mechanical energy, can continuously pump the underground water for use without using any external energy and is energy-saving, environmentally friendly and renewable.

Description

technical field [0001] The invention belongs to the field of irrigation equipment, and specifically relates to a device for extracting groundwater by using solar energy to heat an organic working medium to drive a piston to move and output mechanical energy. Background technique [0002] At present, most of the known solutions to irrigation problems in arid areas are the use of electricity and fossil fuels to drive water pumps for irrigation, which is affected by many aspects such as imperfect power distribution facilities, lack of natural resources, and climate and regional factors. Some existing electric water pumping equipment cannot be effectively used in poor remote and arid areas. At the same time, considering the consumption of natural resources, environmentally unfriendly diesel water pumps are bound to be phased out. Contents of the invention [0003] In order to overcome the defects of existing pumping equipment in terms of energy consumption, the present inventi...
