An anti-shield type energy-saving and environment-friendly solar heat collecting tube

Abstract

The invention discloses an anti-shielding type energy-saving and environment-friendly solar heat collecting tube, which comprises a support frame. The upper turret is rotatably connected to the upper turret through the upper rotatable shaft, and the lower turret is rotatably connected to the support frame through the lower rotatable shaft. A plurality of heat collecting tubes arranged at equal intervals are arranged between the upper turret and the lower turret. A counterweight mechanism for turning over the heat collecting tube is provided between the upper turret and the lower turret. In the present invention, by setting the left counterweight tube and the right counterweight tube, using the left and right weight difference between the left and right counterweight tubes in the water injection process and the difference in pressure during the water injection process, the heat collecting tube is in the initial water injection state. A certain inclination angle increases the contact area between the heat collecting tube and the sun when the sun is in different positions in a day, so as to ensure that the sun's rays always shine on the surface of the heat collecting tube in a straight line.

Description

technical field [0001] The invention relates to the technical field of solar heat collecting tubes, in particular to an anti-shielding energy-saving and environment-friendly solar heat collecting tube. Background technique [0002] Water heaters are one of the indispensable equipment for every household. Solar water heaters are favored by people due to the advantages of cleanliness, environmental protection, and low investment in the later stage. space. [0003] With the development of society, the dust in the air and the concentration of dust in the air have increased significantly. The heat collecting tubes of solar water heaters are easily covered by dust due to long-term exposure to the air, which affects the heat collection efficiency of the heat collecting tubes. At the same time, the existing solar heat collecting tubes are always kept in a horizontal state during the installation process. Due to the different positions of the sun and the different irradiation angles...

Problems solved by technology

[0003] With the development of society, the dust in the air and the concentration of dust in the air have increased significantly. The heat collecting tubes of solar water heaters are easily covered by dust due to long-term exposure to the air, which affects the heat collection efficiency of the heat collecting tubes. At the same time, the existing solar collector tubes are always kept horizontal during the installation process. Due to the different positions of the sun and different irradiation angles in different seasons, the heat absorbed by the solar water heater collector tubes in different seasons is different.
