Description

Technical Field

[0001] The invention belongs to the technical field of supporting and adjusting solar thermal collectors, and in particular relates to an adjustable bracket for solar thermal collectors. Background Art

[0002] Solar thermal collectors are one of the most important devices widely used in the field of solar energy utilization. They mainly reflect or absorb solar radiation to convert light energy into heat energy for hot water, heating or industrial purposes. In order to maximize the efficiency of solar energy capture, solar thermal collectors usually need to be equipped with adjustable brackets to adjust the inclination and direction of the collector to adapt to different geographical locations, seasonal changes and the trajectory of the sun.

[0003] According to the invention patent of Chinese patent CN109520156B, a heat storage solar water heater mounting base that is easy to adjust is disclosed, which is basically described as: including a base, a first motor, a driven gear, a driving gear, a limit plate, a groove, a convex block, a turntable, a fixed column, a spring, a connecting plate, a support seat, a side plate, a connecting block, a rotating shaft, a solar panel, a second motor, a transmission rod, a sleeve, a slide bar, a limit plate, a connecting rod, a telescopic rod, a spiral groove and a limit ring. The present invention has a reasonable structure, and the second motor drives the transmission rod and the sleeve to rotate, and the spiral groove inside the sleeve rotates, so that the slide bar and the connecting rod rise or fall along the direction of the spiral groove rotation, and the solar panel at one end of the side panel rotates a certain angle under the rotation of the support seat, and the other end of the solar panel compresses one end of the spring through the connecting plate, thereby slowing down the rotation amplitude, thereby adjusting the angle of the solar panel and better receiving solar energy.

[0004] But in practice, there are still some problems:

[0005] Traditional bracket structures are designed mainly for stability and lack dynamic wind resistance. When the wind speed is high, the windward area of ​​the reflector and collector is large, and the wind force will cause the bracket to vibrate, tip over or structural damage. At high wind speeds, the center of gravity of the equipment is high and the windward area is too large, resulting in excessive overturning moment generated by the wind, further increasing the safety risks of the equipment. In addition, most traditional brackets do not have automatic cleaning functions. The surface of the reflector is exposed to the outdoor environment for a long time, and it is easy to accumulate dust, impurities, leaves or other pollutants. These pollutants will reduce the reflectivity and light transmission efficiency of the reflective surface, thereby resulting in a decrease in solar energy capture efficiency. Frequent manual cleaning is required, which is not only time-consuming and labor-intensive, but also difficult to achieve efficient maintenance in large-scale application scenarios.

[0006] Based on this, the present invention designs an adjustable bracket for a solar thermal collector to solve the above problems. Summary of the invention

At this time, the bottom end of the reset spring pushes the support to move, and then squeezes the cleaning brush, so that the bottom end of the cleaning brush fits the surface of the reflecting device, effectively removing pollutants such as dust and impurities. When the reflecting device When the other side is adjusted to a higher position, the mounting plate is close to the connecting plate under the action of gravity, and the anti-collision pad on the inner side of the mounting plate provides buffer protection to avoid direct collision between the connecting plate and the mounting plate. Subsequently, the first magnetic attraction and the second magnetic attraction are re-adsorbed and connected under the action of magnetism, and the mechanism is reset. After cleaning the surface of the reflector, the intensity and accuracy of the reflected light can be improved, ensuring that the solar energy is concentrated on the solar collector body to the maximum extent, improving the overall light energy utilization efficiency, and avoiding long-term erosion or wear to damage the performance of the reflector, extending the service life of the equipment, and reducing the cost of maintenance and replacement.
