Technical Field

[0001] The utility model belongs to the technical field of heat collecting plates, and particularly relates to a large-size high-efficiency solar flat plate collector. Background Technique

[0002] The flat plate solar collector is a basic component for low-temperature solar energy utilization. In a solar thermal utilization system, it is a non-concentrating component that receives solar radiation and transfers heat to its heat transfer medium. The flat plate solar collector mainly consists of an absorber plate, a transparent cover plate, a heat insulation layer, and a housing, etc. The absorber structure is basically in a flat plate shape.

[0003] The utility model of 201720610350.9 discloses a high-efficiency solar collector embedded on an inclined tile roof, including a solar heat collecting plate core provided with longitudinal circulation water pipes thereon, a transverse upper header and a lower header respectively arranged at the top and bottom of the solar heat collecting plate core and communicated with the longitudinal circulation water pipes. The characteristics are as follows: a sloping flat plate with a length and width greater than that of the solar collector is arranged at the bottom of the solar collector. Vertical retaining edges are arranged on the left and right sides of the sloping flat plate, and the upper and lower sides are flat edges. A flexible overlapping piece is arranged at the lower part of the flat edge on the lower side. The lower end of the flexible overlapping piece is overlapped with the roof tile below to form a concave-convex groove. However, in the actual use process, since the heat collecting plate is in an open-air environment, dust will adhere to the surface of the heat collecting plate, and the heat absorption efficiency of the heat collecting plate will be reduced due to the accumulated dust.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0027] Please refer to Figure 1 - Figure 6 The present invention provides a technical solution: a large-size high-efficiency solar flat collector, which includes two connecting plates 2, and two connecting plates 3 are connected between the two connecting plates 2. A through groove 4 is provided on one side of the opposite surfaces of the two connecting plates 2, and the same cleaning device 7 is provided in the two through grooves 4. The cleaning device 7 includes a turntable 701. A rotating rod 713 is connected to one side of the turntable 701. One end of the rotating rod 713 is connected to a threaded rod 706. A threaded seat 707 is threadedly connected to the outer wall of the threaded rod 706. A moving block 702 is connected to one side of the threaded seat 707. A sliding sleeve seat 703 is connected to one side of the moving block 702. A sliding rod 704 is slidably connected in the sliding sleeve seat 703. A plugging groove is provided at the bottom of the moving block 702, and a scraping plate 705 is slidably connected to the inner wall of the plugging groove. Two fixing grooves 709 are provided at the top of the scraping plate 705, and a fixing rod 712 is slidably connected in the fixing grooves 709. A first spring 711 is sleeved on the outer wall of the fixing rod 712. Two ends of the first spring 711 are respectively connected to the top of the scraping plate 705 and one side of the inner wall of the plugging groove, and one end of the fixing rod 712 is connected to one side of the plugging groove. One end of the threaded rod 706 is rotatably connected to one side of the inner wall of one of the through grooves 4, and one end of the rotating rod 713 extends out of the through groove 4 where the threaded rod 706 is connected. Both ends of the sliding rod 704 are respectively connected to both sides of the inner wall of the other through groove 4. The outer walls of the threaded seat 707 and the sliding sleeve seat 703 are respectively slidably connected to the inner walls of the two through grooves 4. Two limiting grooves 708 are provided on both sides of the inner wall of the plugging groove provided in the moving block 702, and a limiting block 710 is slidably connected in the limiting grooves 708. One side of the limiting block 710 is connected to one side of the scraping plate 705.

[0028] In the specific implementation manner, by setting the first spring 711, due to the elasticity of the first spring 711, the first spring 711 drives the scraping plate 705 to always be in close contact with the surface of the heat collecting plate 1, thereby ensuring the cleaning efficiency of the scraping plate 705. By setting the fixing rod 712, it is avoided that the compressed first spring 711 is bent, thereby affecting the spring-back effect of the first spring 711. By sliding the sliding sleeve seat 703 on the outer wall of the sliding rod 704, the moving block 702 moves more stably, avoiding deviation and causing jamming to affect the use.

[0029] On one side of the connecting plate 2, two movable slots 5 are provided. On the other side of the connecting plate 2, two connecting slots 6 are provided. And in the two movable slots 5, there is the same installation and disassembly device 8. The installation and disassembly device 8 includes a pull plate 801. On one side of the pull plate 801, a pull handle 802 is connected. On the other side of the pull plate 801, two pull rods 803 are connected. One end of the pull rod 803 is connected with a clamping block 805. A second spring 804 is sleeved on the outer wall of the pull rod 803. One side of the movable slot 5 is communicated with one side of the connecting slot 6. The outer wall of the clamping block 805 is slidably connected with the inner wall of the movable slot 5. And the outer wall of the pull rod 803 is slidably connected with the inner wall of the connecting slot 6. Two ends of the second spring 804 are respectively connected to one side of the inner wall of the movable slot 5 and one side of the clamping block 805. And between the two connecting plates 2, there is a heat collecting plate 1. The other two sides of the heat collecting plate 1 are respectively attached to one side of the two connecting plates 3. And two clamping slots 9 are provided on both sides of the heat collecting plate 1. The clamping block 805 on one side is clamped in the clamping slot 9.

[0030] Specific implementation method: By setting the pull rod 803, when the second spring 804 is compressed, with the support of the pull rod 803, the second spring 804 will not shake left and right when compressed, thereby ensuring the rebound efficiency of the second spring 804. By setting the pull plate 801, the clamping blocks 805 on the same side can be pulled to move simultaneously, thereby improving the convenience of the device during use.

[0031] Working principle: During use, by rotating the turntable 701, the turntable 701 drives the rotating rod 713 to rotate. The rotating rod 713 drives the threaded rod 706 to rotate. The threaded rod 706 drives the threaded seat 707 to move. The threaded seat 707 drives the moving block 702 to move. Further, the moving block 702 drives the scraping plate 705 to move, so that the scraping plate 705 moves on the surface of the heat collecting plate 1. Further, the scraping plate 705 scrapes the dust attached to the surface, thereby ensuring the cleanliness of the surface of the heat collecting plate 1, and thus ensuring the heat absorption efficiency of the heat collecting plate 1. When the heat collecting plate 1 is damaged, by pulling the pull handles 802 to both sides, the pull handles 802 drive the pull plate 801 to move. Further, the pull plate 801 drives the clamping blocks 805 to move through the pull rods 803, so that the clamping blocks 805 are disengaged from the clamping slots 9, and then the damaged heat collecting plate 1 is taken out. Then, the new heat collecting plate 1 is pressed upward, so that the clamping blocks 805 move inward and compress the second spring 804. When the pressing is in place, the clamping blocks 805 are driven by the resilience of the second spring 804 to be reinserted into the clamping slots 9, thereby fixing the new heat collecting plate 1, and thus quickly replacing the damaged heat collecting plate 1.
