Solar gathering and shielding plate and light gathering and shielding method

Abstract

The invention relates to the field of solar water heater, and particularly relates to a solar gathering and shielding plate and a light gathering and shielding method. A temperature controller (1) is arranged on a water tank (8); the solar gathering and shielding plate (2) is arranged at the periphery of a heat collecting water pipe (9); a limit switch (5) is arranged on each of the left and right sides of the end of the solar gathering and shielding plate (2); a gear (3) is connected with the end of the solar gathering and shielding plate (2); the gear (3) is sheathed on the heat collecting water pipe (9); a rubber gasket (10) is arranged in the gear (3); the gear (3) is connected with a worm (4); and the worm (4) is connected with a speed reducer (6) and is connected with a reverse motor (7) after penetrating through the speed reducer (6). The solar gathering and shielding plate can shield the solar light when being placed above the heat collecting water pipe so as to control the water temperature to be blow the boiling point so as to prevent scale formation and scaling on the inner wall of the pipe. When the solar gathering and shielding plate is placed below the heat collecting pipe, the solar gathering and shielding plate can gather the solar light to heat the water quickly.

Description

technical field [0001] The invention relates to the field of solar water heaters, in particular to a solar concentrating sunshade plate and a concentrating sunshade method. Background technique [0002] The current solar energy has no sunshade device. When the sunshine intensity is high, especially in summer, the water in the hot water pipe is always in a high-temperature boiling state, and the temperature cannot be controlled. As a result, the inner wall of the water pipe is easy to scale under the long-term high temperature state, which blocks the water pipe and reduces the water collection. heat effect. And the water in the hot water pipe is boiled at a high temperature for a long time, which will change the water quality and affect human health. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the above-mentioned prior art, and provide a solar concentrating sunshade panel and a concentrating sunshade method. ...

[0002] The current solar energy has no sunshade device. When the sunshine intensity is high, especially in summer, the water in the hot water pipe is always in a high-temperature boiling state, and the temperature cannot be controlled. As a result, the inner wall of the water pipe is easy to scale under the long-term high temperature state, which blocks the water pipe and reduces the water collection. heat effect

Moreover, the water in the hot water pipe will undergo long-term high-temperature boiling, which will change the water quality and affect human health.
