Description

Technical Field

[0001] This invention relates to the field of solar collector mounting brackets, and in particular to a mounting structure for a plate solar collector. Background Technology

[0002] A solar thermal collector is a device that converts solar radiation energy into heat energy. It is mainly used to heat water, air, or other working fluids and is widely used in domestic hot water supply, heating, and industrial heating. Its core function is to absorb solar energy and efficiently transfer heat.

[0003] To increase the sunlight receiving surface area, solar collectors are generally made into a plate shape similar to photovoltaic panels. The surface of solar collectors is prone to the adhesion of foreign objects such as dust, gravel, fallen leaves, and soil. These foreign objects not only block the light and reduce the amount of radiation received, but also cause localized excessively high temperatures (hot spot effect) due to uneven distribution of foreign objects, which affects the service life of the collector.

[0004] To solve the above problems, it is necessary to regularly maintain and clean the surface of the solar collector. However, specialized cleaning equipment is expensive, and the brush bristles can easily scratch the surface of the solar collector during the cleaning process, affecting the light transmittance. The purpose of this invention is to propose a solar collector mounting bracket that can achieve surface cleaning without brushing to solve the above problems and avoid wear on the surface of the solar collector. Summary of the Invention

[0005] The purpose of this invention is to provide an installation structure for a plate solar collector to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a base, a plate collector, a frame, a glass plate, an elastic transparent film, a pressure frame, a winding motor, an unwinding motor, a rubber film, a water inlet pipe, an air inlet pipe, and an air extraction pipe. The base is provided with a support frame, and bolts pass through the opening at the bottom of the support frame and are threaded to the mounting surface to fix the support frame. The number and length of the support frames can be adjusted according to the actual installation requirements.

[0007] The bottom surface of the plate collector is set on the base. The plate collector refers to the plate-shaped solar collector in the prior art, which can convert solar energy into thermal energy. This is prior art and is known to those skilled in the art. Therefore, its specific structure and working principle will not be further explained.

[0008] The frame surrounds the plate collector and is connected to the base. The top of the frame extends toward the plate collector to form an extension. The frame is used to fix the plate collector. In specific implementation, it can be made of corrosion-resistant metals such as stainless steel or aluminum alloy.

[0009] The glass plate is located on the top surface of the plate collector. The glass plate is squeezed by the extension and a plurality of evenly distributed grooves are formed on the surface of the glass plate. The grooves on the glass plate can improve the deformation of the elastic transparent film when it is separated from the glass plate, which helps to peel off foreign objects attached to the elastic transparent film. The glass plate specifically refers to a colorless transparent glass plate. The thickness of the glass plate can be adjusted according to actual needs. The specific material used is not a necessary technical feature or the technical content that the applicant wants to protect. Therefore, there is no need to explain it. As long as the technical solution requirements are met, it is applicable.

[0010] The elastic transparent film covers the top surface of the frame and contacts the extension. A gap is formed between the elastic transparent film and the glass plate. The elastic transparent film refers to a transparent film component made of elastic material. In specific implementation, technicians can select materials that meet the aforementioned requirements based on factors such as manufacturing process and procurement cost, without having a substantial impact on the technical effect.

[0011] The pressure frame is positioned above the elastic transparent film and is fixed to the frame. By fixing the pressure frame to the frame, the elastic transparent film is limited to prevent displacement.

[0012] The winding motor and the unwinding motor are respectively mounted on the frame on both sides of the plate collector.

[0013] One end of the rubber membrane is connected to the shaft of the winding motor, and the other end is connected to the shaft of the winding motor through connecting ropes located on both sides of the rubber membrane. The rubber membrane can cover the pressure frame. The rubber membrane refers to a membrane-like component made of elastic rubber. The specific material used is not a necessary technical feature nor is it the technical content that the applicant wants to protect. Therefore, there is no need to explain it. The connecting rope refers to a rope-like component that plays a connecting role. The connecting rope can be made of, for example, a chain, a thin rope, a water-permeable fabric, or a mesh.

[0014] The water inlet pipe is installed on the frame and is located between the rubber membrane and the elastic transparent membrane. The water inlet pipe is connected to the external water supply equipment / water supply pipe to achieve water inlet.

[0015] The air inlet pipe and the air extraction pipe are respectively connected to the external air pump and the external air pump on the frame. The air inlet pipe and the air extraction pipe are located in the gap and communicate with the gap.

[0016] To optimize the above technical solution, further measures are taken, including: a roller is also included. The roller is embedded in the pressure frame and forms a rotating pair with the pressure frame. The roller abuts against the rubber membrane. During the winding and unwinding process of the rubber membrane by the winding motor and the unwinding motor, the roller can abut against the rubber membrane. By rolling, the sliding friction is changed into rolling friction, which reduces the wear between the rubber membrane and the pressure frame, and at the same time improves the smoothness of the rubber membrane during movement.

[0017] As a further improvement to the above technical solution: a metal mesh is embedded inside the rubber membrane. The metal mesh is composed of interlaced metal wires distributed inside the rubber membrane to prevent the rubber membrane from tearing.

[0018] As a further improvement to the technical solution: an electromagnet is installed inside the frame. The electromagnet can attract the metal mesh, thus ensuring that the edge of the rubber membrane can be tightly pressed against the frame to achieve a sealing effect. The electromagnet refers to a device that can generate magnetism when energized in the prior art. It is prior art and known to those skilled in the art. Therefore, its specific structure and working principle will not be further explained. Technicians can adjust the attraction between the electromagnet and the metal mesh by changing the specifications or power of the electromagnet. Technicians can select the material of the metal mesh according to actual needs. As long as it meets the aforementioned requirements, it is applicable.

[0019] As an improvement to the aforementioned technical solution: a sealing groove is provided on the top surface of the pressure frame. The sealing groove is located directly above the electromagnet. When the electromagnet is energized, it attracts the metal mesh, which can drive the rubber membrane to embed into the sealing groove. The rubber membrane is stuck in the sealing groove and deforms elastically, which can further improve the blocking effect of the rubber membrane on the water flow.

[0020] Furthermore, the air inlet pipe, air extraction pipe, and water inlet pipe are all equipped with one-way valves to prevent airflow and water flow from flowing back into the pipes and affecting the normal operation of the equipment.

[0021] Furthermore, the pressure frame and the frame are detachably connected. When the elastic transparent film is damaged, technicians can replace the elastic transparent film by disassembling the pressure frame. In specific implementation, bolts can be used to pass through the pressure frame and the frame to achieve a detachable connection between the pressure frame and the frame, which is convenient and quick to disassemble and assemble.

[0022] Furthermore, the pressure frame has outwardly inclined drainage grooves on both sides. The drainage grooves can be covered by a rubber membrane. The drainage grooves are used to guide the water flow outward. When the drainage grooves are covered by the rubber membrane, the rubber membrane can block the drainage grooves and prevent the water flow outward.

[0023] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

[0024] A. By wrapping an elastic transparent membrane on both sides with a liquid layer and an air layer, the elastic transparent membrane generates irregular vibrations during water injection, which can separate foreign objects attached to the elastic transparent membrane. No brushing is required, which can avoid surface scratches affecting the light transmittance of the plate collector.

[0025] B. By blocking water flow through the rubber membrane, the leakage of water from the gap between the rubber membrane and the pressure frame during the water injection process can be reduced. It is suitable for plate collectors with various inclinations and has a wide range of applications.

[0026] C. It uses an elastic transparent membrane to block foreign objects, and the cleaning target is concentrated on the elastic transparent membrane, so it is suitable for integrated plate collectors / multi-piece combined plate collectors. Attached Figure Description

[0049] The base 1 is provided with a support frame 101;

[0050] The bottom surface of the plate collector 2 is mounted on the base 1;

[0051] The frame 3 surrounds the plate collector 2 and is connected to the base 1. The top of the frame 3 extends toward the plate collector 2 to form an extension 301. An electromagnet is provided inside the frame 3.

[0052] The glass plate 4 is located on the top surface of the plate collector 2. The glass plate 4 is pressed by the extension 301, and a plurality of uniformly distributed grooves 401 are formed on the surface of the glass plate 4.

[0053] The elastic transparent film 5 covers the top surface of the frame 3 and contacts the extension 301, and a gap 501 is formed between the elastic transparent film 5 and the glass plate 4.

[0054] The pressure frame 6 is positioned above the elastic transparent film 5. The pressure frame 6 and the frame 3 are detachably fixed. The pressure frame 6 also includes a roller 601. The roller 601 is embedded in the pressure frame 6 and forms a rotating pair with the pressure frame 6. The roller 601 abuts against the rubber film 9. The pressure frame 6 has outwardly inclined drainage grooves 603 on both sides. The drainage grooves 603 can be covered by the rubber film 9. The top surface of the pressure frame 6 also has a sealing groove 602, which is located directly above the electromagnet.

[0055] The winding motor 7 and the unwinding motor 8 are respectively mounted on the frame 3 on both sides of the plate collector 2;

[0056] One end of the rubber membrane 9 is connected to the shaft of the winding motor 7, and the other end is connected to the shaft of the winding motor 7 through the connecting ropes 901 located on both sides of the rubber membrane 9. The rubber membrane 9 can cover the pressure frame 6. A metal mesh is embedded inside the rubber membrane 9. The electromagnet can attract the metal mesh. The pressure frame 6 has outwardly inclined drainage grooves 603 on both sides. The drainage grooves 603 can be covered by the rubber membrane 9.

[0057] The water inlet pipe 10 is disposed on the frame 3, and the water inlet pipe 10 is located between the rubber membrane 9 and the elastic transparent membrane 5;

[0058] The air inlet pipe 11 and the air extraction pipe 12 are respectively connected to the external air pump and the air extraction pump on the frame 3. The air inlet pipe 11 and the air extraction pipe 12 are located in the gap 501 and communicate with the gap 501. One-way valves are provided inside the air inlet pipe 11, the air extraction pipe 12 and the water inlet pipe 10.

[0059] Working principle: During the solar energy collection process of the plate collector 2, the winding motor 7 winds up the rubber film 9. At this time, the rubber film 9 does not act as a shading agent, and sunlight can pass through the elastic transparent film 5 and the glass plate 4 to directly irradiate the plate collector 2 without affecting the normal operation of the plate collector 2. The groove 401 on the glass plate 4 can increase light scattering, extend the light path, and reduce reflection loss, without reducing the heat collection efficiency of the plate collector 2.

[0060] Because of the barrier effect of the elastic transparent membrane 5, foreign objects such as dust, gravel, and fallen leaves will not directly adhere to the surface of the plate collector 2. For Embodiments 1 and 2, when it is necessary to clean the foreign objects attached to the elastic transparent membrane 5, air is injected into the gap 501 through the air inlet pipe 11. At this time, the elastic transparent membrane 5 separates from the glass plate 4. Then, the unwinding motor 8 drives the rubber membrane 9 to move and close the space above the elastic transparent membrane 5. Subsequently, water is injected through the water inlet pipe 10. Because the surface of the glass plate 4 has grooves 401 that are uneven, the foreign objects are easily peeled off from the elastic transparent membrane 5 after the elastic transparent membrane 5 separates from the glass plate 4. Moreover, the injected air will form an air layer below the elastic transparent membrane 5, and the water will form a liquid layer above the elastic transparent membrane 5. During the water injection process, the elastic transparent membrane 5 will produce irregular vibrations as the water is injected, thereby cleaning the foreign objects on the elastic transparent membrane 5. No brushing is required during the process, which can avoid scratching the surface of the plate collector 2 and the elastic transparent membrane 5.

[0061] After the foreign object is removed, the rewinding motor 7 rewinds the rubber membrane 9. At this time, the water flow can carry the foreign object out from the frame 3 and the drain trough 603. To improve the cleaning effect, the above process can be repeated. Then the air extraction pipe 12 discharges the air in the gap 501, and the elastic transparent membrane 5 is reset and tightly attached to the surface of the glass plate 4.

[0062] In Example 2, when the unwinding motor 8 drives the rubber membrane 9 to move and close the space above the elastic transparent membrane 5, the electromagnet is activated to attract the metal mesh inside the rubber membrane 9. The rubber membrane 9 is attracted and can stick tightly to the pressure frame 6, which can reduce the water flow from the gap between the rubber membrane 9 and the pressure frame 6 during the water injection process. It can be applied to plate collectors 2 with various inclinations.

[0063] The control method of this invention is to achieve automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
