Solar water heater capable of precisely adjusting light receiving angle

Abstract

The invention relates to a solar water heater capable of precisely adjusting a light receiving angle, and belongs to the technical field of solar equipment. The solar water heater comprises a water tank, a base, a bottom communicating vessel, vacuum tubes, a height adjusting mechanism, a horizontal adjusting mechanism and an angle detection mechanism, wherein the water tank is connected with the bottom communicating vessel through the plurality of vacuum tubes, one end of the height adjusting structure is arranged on the base, the other end of the height adjusting structure is connected with the water tank, one end of the horizontal adjusting mechanism is installed on the base, the other end of the horizontal adjusting mechanism is connected with the bottom communicating vessel. The heightadjusting mechanism and the horizontal adjusting mechanism are arranged so that an included angle between the vacuum tubes and the ground can be adjusted, the angle detection mechanism is arranged sothat the included angle between the vacuum tubes and the ground can be detected, then the angles of the vacuum tubes for receiving irradiating of sunlight are adjusted, and then the use efficiency ofthe solar water heater is improved.

[0002] Solar water heater is a heating device that converts solar energy into heat energy. It heats water from low temperature to high temperature to meet the needs of hot water in people's life and production. Vacuum tube solar water heaters are the main ones. Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks and brackets and other related parts. The conversion of solar energy into heat mainly depends on vacuum heat collecting tubes. The vacuum heat collecting tubes use the principle of hot water to float and sink. Make the water produce microcirculation to obtain the required hot water; the solar water heater technology in the prior art is relatively mature, but because the earth revolves around the sun, the altitude angle of the sun at noon is different throughout the year, and the sunlight shines on the solar vacuum tube. The above angles are also different. When the sun altitude angle is 90°, the solar radiation intensity is the largest and the utilization rate of the vacuum tube is the highest; The technology for adjusting the receiving angle of solar energy is still immature, and there is still the problem that the angle adjustment mechanism is not accurate enough; in addition, if the vacuum degree of the vacuum tube is reduced, because each vacuum tube is connected in series, it will affect the use of the entire solar energy and reduce the use efficiency of the solar energy; When the sun's light intensity is weak in cloudy and rainy days, the heating efficiency of Tianyang Energy will be greatly reduced, which will affect people's normal use
