Description

Technical Field

[0001] The utility model relates to the technical field of fixing a flat-plate solar thermal collector, in particular to a fixing piece used for a flat-plate solar thermal collector. Background Art

[0002] Flat-plate solar collectors are basic components for low-temperature solar thermal utilization. They are non-concentrating components in solar thermal utilization systems that receive solar radiation and transfer heat to their heat transfer media. Flat-plate solar collectors are mainly composed of a heat-absorbing plate, a transparent cover, an insulating layer, and an outer shell. The heat-absorbing structure is basically in the shape of a flat plate. When the flat-plate solar collector is working, solar radiation passes through the transparent cover and is projected onto the heat-absorbing plate, where it is absorbed and converted into thermal energy. The heat is then transferred to the heat transfer media in the heat-absorbing plate, raising the temperature of the heat transfer media. As the useful energy output of the collector, flat-plate solar collectors have been widely used in many fields such as domestic water heating, swimming pool heating, industrial water heating, building heating and air-conditioning, etc.

[0003] The existing fixings for flat-plate solar collectors cannot adjust the angle according to needs. For example, the fixing mechanism of a support frame for a solar collector panel disclosed in application number CN201922241971.6, the angle of the support frame body in the patent is fixed and cannot be adjusted, but the angle of the sun will change with the seasons. Therefore, if the angle of the flat-plate solar collector cannot be adjusted, the collector will not be able to receive sunlight at the optimal angle in certain seasons, thereby affecting its ability to absorb solar energy and reducing the collection efficiency.

[0004] Therefore, it is necessary to invent a fixing member for a flat-plate solar thermal collector to solve the above problems. Summary of the invention

[0007] Preferably, a hinge connection is provided between the bottom of the fixed frame and above the bottom plate, and a hinge connection is provided between the top of the fixed frame and the top of the support, so that the angles of the fixed frame and the support can be adjusted.

[0008] Preferably, three bushings are provided. The three bushings are movably connected to the rotating shaft, and the center lines of the three bushings coincide with the center line of the rotating shaft, so that the support can be synchronously adjusted when the bushings rotate on the rotating shaft.

[0009] Preferably, the installation frame is designed in a "U" shape structure, and the installation frame is slidably connected to the collector body, so that the collector body can be slidably disassembled and assembled on the installation frame.

[0010] Preferably, the slider is slidably connected to the chute. The slider is designed in a "convex" shape structure, and two sliders are provided, so that the slider and the chute form a sliding disassembly and assembly method for the installation frame and the collector body.

[0011] Preferably, two shaft seats and support plates are provided. The shaft seats and the support plates are hinged, the support plates and the adjusting screw are threadedly connected, and a limiting plate is fixedly installed at the bottom of the adjusting screw, so that the position of the limiting plate can be adjusted by rotating the support plate.

[0012] Preferably, an anti-slip pad is fixedly installed at the bottom of the limiting plate. The anti-slip pad is a silicone pad, and the anti-slip pad is fixedly adhered to the limiting plate through an adhesive, so that the anti-slip pad can enhance the friction between the limiting plate and the collector body and enhance its anti-slip performance.

[0015] 1. Through the arrangement of the rotating shaft and the bushings, the fixed frame and the support are connected by a hinge connection through the rotating shaft and the bushings. Thus, the angle of the fixed frame can be adjusted according to the change of the sun's angle, and the flat solar collector can also be adjusted accordingly, so that it always receives sunlight at the optimal angle, thereby improving the heat collection efficiency;

[0016] 2.
