Heat collection plate rotating structure on solar water heater

Abstract

The invention discloses a heat collection plate rotating structure on a solar water heater. The heat collection plate rotating structure comprises a supporting frame, a heat collecting plate, a rotating assembly and an angle changing mechanism; the two sides of the heat collecting plate are fixed on the supporting frame through a rotating shaft; a curved water pipe is flatly arranged on the heat collecting plate; a water inlet pipe is connected to a water source; a water outlet pipe is connected with a heat insulation water storage device; one end of the supporting frame is provided with the angle changing mechanism; the rotating shaft is provided with the rotating assembly; and the supporting frame is vertically fixed to the two ends of a base. The invention adopts the photoelectric detecting sensor to illuminate the light intensity on the heat collecting plate, and feeds the signal to the control system to rotate the motor. An photoelectric detection sensor is adopted for feeding signals back to a control system through light intensity irradiated on the heat collecting plate, the motor is enabled to rotate, by arranging the heat collecting plate in the mode, the angle can be automatically rotated, thus, sunlight is kept irradiating perpendicularly, the heat collecting effect is effectively improved, especially in the limited area of the top floor of a building, the function of the heat collection plate rotating structure can be achieved more completely, and the overall structure is high in practicability and simple in structure.

Description

technical field [0001] The invention relates to solar heat collector equipment, in particular to a rotating structure of a heat collecting plate on a solar water heater. Background technique [0002] A solar collector is a device that converts the sun's radiant energy into thermal energy, and heats water from low temperature to high temperature to meet the needs of hot water in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structure. Vacuum tube solar water heaters are the main ones, accounting for 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 accessories. The conversion of solar energy into heat mainly depends on the heat collecting tubes. hot water. [0003] At present, there are many types of solar water heaters with different structures, but they al...

Problems solved by technology

Since the solar energy is relatively scattered, it must be concentrated, so the collector is a key part of various solar energy devices. At present, a large part of the solar collector is used in the heat collecting solar water heater. With more and more The use of solar water heaters has gradually exposed many defects of heat collecting solar water heaters. For example, the solar heat collecting plate can only stand obliquely and form a fixed angle with the sunlight, which cannot be changed, and requires a relatively heavy bracket; the light-transmitting panels are mostly made of glass, which is easy to break , the light transmittance is low, the heat collector box is required to have a certain rigidity, and it cannot be deformed
