Hydrodynamic self-cleaning solar water heater

Abstract

The invention discloses a hydrodynamic self-cleaning solar water heater. The hydrodynamic self-cleaning solar water heater comprises a water storage tank and a supporting base which are arranged up and down, wherein a plurality of heat collecting pipes are fixedly installed on the front side between the water storage tank and the supporting base at equal intervals, a support is connected to the rear side between the water storage tank and the supporting base jointly, and the supporting base is composed of a first step plate, a second step plate and a third step plate which are integrally formed from bottom to top. The hydrodynamic self-cleaning solar water heater has the advantages that rainwater accumulated in the water tank is used for generating water pressure on a pressure valve in rainy days, the rainwater automatically flows into a hydrodynamic cavity through a water outlet pipe to impact a waterwheel, a first bevel gear and a second bevel gear which are meshed with each other drive two synchronous belts to transmit in opposite directions, a lifting plate and a cleaning sleeve are driven to move upwards, therefore, the heat collecting pipes are cleaned, then a clockwork spring device is used for rotating reversely to drive the lifting plate and the cleaning sleeve to move downwards, the heat collecting pipes are cleaned again, furthermore, the cleaning effect is better inrainy days, manual cleaning is not needed, and the heat conversion efficiency of solar energy is high.

Description

technical field [0001] The invention relates to the technical field of solar water heaters, in particular to a water-driven self-cleaning solar water heater. Background technique [0002] Evacuated tube solar water heater is the most commonly used in people's life as a heating device that does not need electric energy and can convert sunlight energy into heat energy. The vacuum tube solar water heater is composed of heat collecting tubes, water storage tanks and brackets and other related parts. The conversion of solar energy into heat mainly depends on the vacuum heat collecting tubes. hot water required. [0003] In the process of long-term use of vacuum tube solar water heaters, dust will adhere to the outer surface of the vacuum heating tube, which seriously reduces the efficiency of solar energy conversion into heat energy and affects people's domestic water, and it is usually installed on the roof, which is inconvenient to clean. [0004] In order to solve the above ...
