Description

Technical Field

[0001] The present invention relates to the technical field of collector auxiliary equipment, and specifically relates to a support device for a large flat collector. Background Technique

[0002] A collector, also known as a heat collection plate, is the name given by the solar energy industry to the outdoor heat collection component of a solar water heater. A solar collector with good performance is one of the key devices of a solar air conditioner. Its main function is to collect the heat energy in sunlight and transfer it to a water tank through a connecting pipeline to heat the cold water in the water tank. Mature solar collectors mainly include: flat collectors, all-glass evacuated tube collectors, and heat pipe evacuated tube collectors. Among them, flat collectors are widely used all over the world due to their simplicity, low cost, and easy installation.

[0003] A flat collector is composed of four parts: a heat collection plate, a transparent cover plate, a heat insulation layer, and a housing. Its heat absorption element, the heat collection plate, is a metal heat absorption plate (usually copper or aluminum), and the surface of the heat absorption plate is a solar selective absorption coating; the middle of the heat absorption plate is a medium flow channel. A collector is composed of several heat absorption plates and upper and lower heat collection tubes welded together, with a metal outer frame and a back insulation material, and high-transmittance glass on the top.

[0004] Due to its large area and heavy weight, a large flat collector is generally inclined and fixed on a large bracket, and the bracket itself only serves as a support. However, the heat absorption efficiency of the flat collector is closely related to the irradiation angle. If it is only installed at a certain angle, the heat absorption efficiency is low, and it is greatly affected by the weather. In case of rain, snow or sleet, if no protection is carried out, the coating on the surface of the heat collection plate will also be damaged, affecting the heat absorption efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a support device for a large flat collector to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A support device for a large flat collector, including a base, a moving component, a deflection mechanism, a fixing frame, a solar panel, a cleaning mechanism, and a solar panel control system.

The filter is used to purify and filter the rainwater. The water tank is used to store the excess accumulated water in the water storage area. During dry days, the water storage area directly extracts the stored water in the water tank.

[0012] Furthermore, the cleaning wheel group includes two cleaning rollers, cleaning cotton blocks, slide rails, sliders, and a drive module.

[0033] The cleaning wheel set 63 includes two cleaning rollers 631, cleaning cotton blocks 632, a slide rail 633, a slider 634 and a driving module 635. The slide rail 633 is arranged on both sides of the cleaning frame 61, the slider 634 is slidably matched with the slide rail 633, both ends of the cleaning roller 631 are rotatably connected to the slider 634, the cleaning cotton blocks 632 are sleeved on the surface of the cleaning roller 631, and the driving module 635 is connected to the slider 634.

[0034] It should be noted that: The driving module 635 preferably but not limited to a structure driven by a screw, a motor and a pulley, and is used to drive the cleaning roller 631 to move up and down; the cleaning cotton blocks 632 are preferably made of sponge material with soft texture and good water absorption; the infrared detection module 64 is signal-connected to the solar panel control system and is used to detect whether there is dirt residue on the surface of the solar panel 5; the cleaning roller 631 is provided with a pressure sensing module to avoid hitting the solar panel 5 during movement.

[0035] The moving assembly 2 includes a carriage 21, a fixing plate 22, two screws 23, a plurality of rotating teeth 24 and a driving motor 25. The carriage 21 is slidably arranged in the base 1, the fixing plate 22 is installed in the carriage 21, the two screws 23 are arranged through the base 1 and are in threaded cooperation with the carriage 21 and the fixing plate 22, the driving motor 25 is arranged on one side of the base 1, and the rotating teeth 24 are respectively sleeved on the screws 23 and the driving end of the driving motor 25.

[0036] A slide rail is arranged in the base 1 in cooperation with the carriage 21. In actual operation, the driving motor 25 drives each rotating tooth 24 to rotate through forms such as chain drive, indirectly drives the two screws 23 to rotate, thereby realizing the movement of the carriage 21 and the fixing plate 22, and finally causing the solar panel 5 to be displaced.

[0037] In this embodiment, the implementation method is as follows:

[0038] Step 1: The sunlight angle sensor 39 continuously feeds back the detected direct sunlight condition to the solar panel control system;

[0039] Step 2: The solar panel control system analyzes whether the solar panel 5 forms a perpendicular angle with the sunlight in terms of the direct sunlight direction and angle. If not, it controls the deflection mechanism 3 to drive the solar panel 5 to deflect until it is corrected to the vertical state.

[0040] Step 3: The deflector 623 feeds back the detected temperature and pressure signals to the solar panel control system.

[0041] Step 4: The solar panel control system analyzes whether there is rain or snow based on the changes in temperature and pressure signals. If so, it controls the deflection mechanism 3 to drive the solar panel 5 to deflect to a state parallel to the ground, and then controls the moving component 2 to drive the solar panel 5 to move under the cleaning frame 61 for shelter.

[0042] Step 5: The moving component 2 drives the solar panel 5 to pass in front of the infrared detection module 64. The infrared detection module 64 detects the surface state of the solar panel 5 and feeds it back to the solar panel control system.

[0043] Step 6: The solar panel control system determines whether there are impurities on the surface of the solar panel 5. If so, it detects the water storage state in the water storage area 622. After waiting for sufficient water, it controls the moving component 2 and the cleaning wheel group 63 to clean the surface of the solar panel 5.

[0044] Specifically, in Step 3, it is possible to judge whether there is snowfall based on the temperature signal detected on the surface of the deflector 623. For the position where snowflakes fall, there will be a low-temperature signal that is significantly different from other areas, so it can be judged that there is snowfall; judge whether there is rain or hail based on the pressure signal detected on the surface of the deflector 623. For the position where rain or hail falls, there will be a pressure signal that is significantly different from other areas, so it can be judged. The solar panel control system can retract the solar panel 5 according to the actual weather conditions to protect its surface from being damaged.

[0045] In Step 5, the infrared detection module 64 is used to measure the distance to the solar panel 5. If there is no debris (leaves, stones) attached to the surface of the solar panel 5, only the distance reaching the inner wall on the other side of the cleaning frame 61 will be detected at the height of the surface of the solar panel 5. If there is debris, the infrared detection module 64 will detect a short-distance signal, and thus it can be judged whether the surface of the solar panel 5 needs to be cleaned.

[0046] In Step 6, the cleaning wheel group 63 judges whether the cleaning wheel group 63 has descended to the surface of the solar panel 5 according to the pressure signal detected by the cleaning roller 631. Then the solar panel control system controls the water pump 625 to start and controls the moving component 2 to drive the solar panel 5 to move back and forth to clean the impurities on its surface through the cleaning cotton block 632.
