Protective device for solar water heater and use method thereof

Abstract

The invention discloses a protective device for a solar water heater and a use method of the protective device for the solar water heater and relates to the technical field of solar water heaters. Theprotective device comprises a protective mechanism, a remote controller, a cleaning mechanism, a group of first supporting plates and a second supporting plate. The protective mechanism comprises a first fixing plate, a first motor and a second protective plate. One surface of the first fixing plate is fixedly connected with one surface of a second supporting plate. An electric pushing rod is fixed to one surface of the first fixing plate. According to the protective device for the solar water heater, a PLC is controlled through the remote controller, the PLC is made to control the electric push rod to drive a first protective plate to move to above a plurality of vacuum pipe bodies to protect the vacuum pipe bodies, the PLC controls the first motor to drive the second protective plate toslide upward through a first lead screw, and therefore comprehensive protection of the vacuum pipe bodies is achieved; the vacuum pipe bodies are not prone to being damaged by collision with foreignmatter, financial loss of a user is avoided, and therefore the solar water heater can provide better service for the user.

Description

technical field [0001] The invention belongs to the technical field of solar water heaters, and in particular relates to a protective device for solar water heaters and an application method thereof. Background technique [0002] A solar water heater is a device that uses sunlight to heat water. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters. Vacuum tube solar water heaters occupy 95% of the domestic market share. Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly depends on the vacuum heat collecting tubes. Using the principle of hot water floating and cold water sinking, the water produces microcirculation to achieve the required hot water. With the development of society, the price of solar water heaters continues to decrease and can be accepted by more and more families, making the ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a protective device for solar water heaters and its use method. The PLC controller is controlled by the remote controller, so that the PLC controller controls the electric push rod to drive the first protective plate to run above the vacuum tube body to protect several vacuum tube bodies. At the same time, the PLC controller controls the first motor to drive the second protective plate to slide upward through the first threaded screw rod, so as to comprehensively protect several vacuum tube bodies, and solve the problem that the vacuum tube body of the existing solar water heater is easily affected by the collision of foreign objects. Damage occurs, making the solar water heater unusable and causing losses to users
