Anti-shielding type energy-saving and environment-friendly solar heat collecting pipe

Abstract

The invention discloses an anti-shielding type energy-saving and environment-friendly solar heat collecting pipe which comprises a supporting frame. A water tank is fixedly connected to the upper end face of the supporting frame, a water inlet pipe is arranged on the right side end face of the water tank, and an upper rotating frame is rotationally connected to the side wall of the lower end of the water tank through an upper rotating shaft; and the supporting frame is rotationally connected with a lower rotating frame through a lower rotating shaft, a plurality of heat collecting pipes arranged at equal intervals are arranged between the upper rotating frame and the lower rotating frame, and a balance weight mechanism used for achieving overturning of the heat collecting pipe is arranged between the upper rotating frame and the lower rotating frame. According to the anti-shielding type energy-saving and environment-friendly solar heat collecting pipe, by arranging a left counterweight pipe and a right counterweight pipe, the heat collecting pipe is inclined at a certain angle in an initial water injection state by utilizing the sequence of the left counterweight pipe and the right counterweight pipe in the water injection process and the left and right weight difference generated by different pressures in the water injection process, so that the contact area between the heat collecting pipe and the sun when the sun is located at different positions in one day is increased, and it is guaranteed that sunlight always irradiates the surface of the heat collecting pipe in a linear state.

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...

[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.
