Description

Technical Field

[0001] This invention relates to the field of flat-plate solar collector technology, and in particular to a windproof and reinforced structure and a flat-plate solar collector assembly. Background Technology

[0002] With the growth of global energy demand and the depletion of fossil fuel resources, developing new energy sources has become an important way to address the energy crisis and reduce greenhouse gas emissions. Solar energy, as a clean and renewable energy source, has attracted widespread attention. Flat-plate solar collectors are devices that can effectively utilize solar energy and have broad market demand.

[0003] In most cases, flat-plate solar collectors need to be installed at a certain angle to the horizontal plane. The size of the angle needs to take into account many factors such as the local latitude, installation location, usage scenario, and usage time. The specific installation method is to fix the upper mounting hole on the back of the flat-plate solar collector to the upper mounting position with bolts, and fix the lower back of the flat-plate solar collector to the lower mounting position with bolts.

[0004] Because of its inclined installation, the front and back of the flat-plate solar collector are exposed to wind. Under prolonged wind conditions, especially when the ambient wind is strong, the bolts used to secure the ends of the flat-plate solar collector are subjected to significant shear forces, making them prone to breakage and causing the collector to fall and become damaged. Summary of the Invention

[0005] The purpose of this invention is to provide a windproof and reinforced structure and a flat plate solar collector assembly to solve the problems existing in the above-mentioned related technologies and improve the fixation stability of the flat plate solar collector.

[0006] To achieve the above objectives, the present invention provides the following solution:

[0007] This invention discloses a windproof reinforcement structure, comprising:

[0008] The U-shaped groove has a plate 1, a plate 2, and a plate 3. The two ends of the plate 3 are respectively fixedly and perpendicularly connected to the plate 1 and the plate 2. The plate 1 is used to contact and limit the front end of the flat plate collector, the plate 2 is used to contact and limit the back end of the flat plate collector, and the plate 3 is used to contact and limit the side end of the flat plate collector, so as to restrict the end of the flat plate collector inside the U-shaped groove.

[0009] The connector is fixedly connected to the U-shaped groove and has mounting holes through which bolts pass.

[0010] Preferably, the area of ​​the first plate is smaller than the area of ​​the second plate.

[0011] Preferably, the widths of plate one, plate two, and plate three are the same, and the length of plate one is less than the length of plate two.

[0012] Preferably, the connector is L-shaped, including plate four and plate five, plate four and plate five are perpendicularly and fixedly connected; plate four is fitted and fixedly connected to plate two, plate five is perpendicular to plate three, and the mounting hole is located on plate five.

[0013] Preferably, the width of plate four is the same as that of plate five, and the length of plate four is less than that of plate five.

[0014] The present invention also discloses a flat plate solar collector assembly, including the above-mentioned windproof and reinforced structure, and further including a flat plate solar collector, an upper fastening assembly, an upper support, a lower fastening assembly, and a lower support;

[0015] The number of windproof reinforcement structures is multiple, including upper reinforcement structures and lower reinforcement structures;

[0016] The upper end of the flat plate solar collector is inserted into the U-shaped groove of the upper reinforcing structure, and the lower end of the flat plate solar collector is inserted into the U-shaped groove of the lower reinforcing structure;

[0017] The upper fastening assembly includes an upper bolt and an upper nut; the upper bolt passes through the mounting hole of the upper reinforcement structure, the flat plate collector, and the upper support, and is locked by the upper nut;

[0018] The lower fastening assembly includes a lower bolt and a lower nut; the lower bolt passes through the mounting hole of the lower reinforcement structure, the flat plate collector, and the lower support, and is locked by the lower nut.

[0019] Preferably, the connector of the upper reinforcing structure is clamped between the upper nut and the upper support;

[0020] The connector of the lower reinforcement structure is clamped between the lower nut and the lower support.

[0021] Preferably, the upper fastening assembly further includes an upper cotter pin, which is mounted on the thread of the upper bolt and located on the side of the upper nut away from the head of the upper bolt; the lower fastening assembly further includes a lower cotter pin, which is mounted on the thread of the lower bolt and located on the side of the lower nut away from the head of the lower bolt.

[0022] Preferably, the upper support includes a support rod and a mounting base one, the lower end of the support rod is fixedly connected to the mounting base one, and the upper bolt passes through the upper end of the support rod; the lower support includes a mounting base two; the mounting base one and the mounting base two have the same structure and are used to fix it to the ground.

[0023] Preferably, the back of the flat plate solar collector has ribs extending along its width direction, the ribs extending from the upper end to the lower end of the flat plate solar collector, the upper bolt passing through the upper end of the ribs, and the lower bolt passing through the lower end of the ribs.

[0024] Compared with related technologies, the present invention achieves the following technical effects:

[0025] After the end of the flat plate solar collector is inserted into the U-shaped groove, plate one can abut and limit the front of the flat plate solar collector, plate two can abut and limit the back of the flat plate solar collector, and plate three can abut and limit the side of the flat plate solar collector. Therefore, the displacement of the flat plate solar collector can be limited from three directions, thereby improving the stability of the flat plate solar collector.

[0026] After the windproof reinforcement structure is installed, the bolts not only pass through the corresponding mounting holes on the flat plate collector, but also through the mounting holes on the connector. This increases the number of positions where the bolts bear shear force and reduces the maximum shear force that a single stress point on the bolt can withstand, thereby minimizing the risk of bolt breakage.

[0027] Since the windproof reinforcement structure is not fixed to the flat plate solar collector, but is independent of it, the number and location of the windproof reinforcement structure can be selected according to the actual situation, which improves the adaptability to the installation environment.

[0028] In a preferred embodiment of the invention, the connector of the upper reinforcing structure is clamped between the upper nut and the upper support. The connector of the lower reinforcing structure is clamped between the lower nut and the lower support. By selecting this connection position, the upper reinforcing structure can be installed and removed without moving the upper bolt, and the lower reinforcing structure can be installed and removed without moving the lower bolt. Only the upper and lower nuts need to be removed during installation and removal. This avoids the need to remove the upper and lower bolts and also avoids lifting the flat plate collector, greatly improving operational convenience and safety.

[0029] In a preferred embodiment of the present invention, the upper cotter pin, after being inserted into the threaded rod of the upper bolt, prevents the upper nut from falling off. Similarly, the lower cotter pin, after being inserted into the threaded rod of the lower bolt, prevents the lower nut from falling off. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] The purpose of this invention is to provide a windproof and reinforced structure and a flat plate solar collector assembly to solve the problems existing in the above-mentioned related technologies and improve the fixation stability of the flat plate solar collector.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Figure 4 The diagram shows the wind force decomposition diagram of the front and back of the flat plate solar collector 2 when exposed to wind.

[0039] Reference Figures 1-4 This embodiment provides a windproof reinforcement structure 1, including a U-shaped groove 11 and a connector 12.

[0040] The U-shaped channel 11 has a first plate 111, a second plate 112, and a third plate 113. The two ends of the third plate 113 are vertically and fixedly connected to the first plate 111 and the second plate 112, respectively. The first plate 111 is used for contact and limitation with the front end of the flat plate collector 2, the second plate 112 is used for contact and limitation with the back end of the flat plate collector 2, and the third plate 113 is used for contact and limitation with the side end of the flat plate collector 2, thereby confining the end of the flat plate collector 2 within the U-shaped channel 11. A connector 12 is fixedly connected to the U-shaped channel 11 and has mounting holes 123 for bolts to pass through.

[0041] The working principle of the windproof reinforcement structure 1 in this embodiment is as follows:

[0042] After the end of the flat plate solar collector 2 is inserted into the U-shaped groove 11, the first plate 111 can abut and limit the front of the flat plate solar collector 2, the second plate 112 can abut and limit the back of the flat plate solar collector 2, and the third plate 113 can abut and limit the side of the flat plate solar collector 2. Therefore, the U-shaped groove 11 can limit the displacement of the flat plate solar collector 2 from three directions, thereby improving the stability of the flat plate solar collector 2.

[0043] After the windproof reinforcement structure 1 is installed, the bolts not only pass through the corresponding mounting holes on the flat plate collector 2, but also through the mounting holes 123 on the connector 12. This increases the number of positions where the bolts bear shear force and reduces the shear force borne by a single stress position of the bolt, thereby minimizing the risk of bolt breakage.

[0044] Since the windproof reinforcement structure 1 is not integrally connected to the flat plate collector 2, but is independent of the flat plate collector 2, the number and installation position of the windproof reinforcement structure 1 can be selected according to the actual situation, which improves the adaptability to the installation environment.

[0045] In some examples, gaskets are provided between plate 111 and plate collector 2, between plate 212 and plate collector 2, and between plate 313 and plate collector 2.

[0046] To facilitate installation, the distance between plate 111 and plate 112 (i.e., the length of plate 113) is generally slightly greater than the thickness of the flat plate solar collector 2. When the flat plate solar collector 2 moves within the groove 11, it is easily scratched due to collisions with the groove 11. This embodiment uses a gasket to fill the gap between the groove 11 and the flat plate solar collector 2, preventing collisions. The gasket can be made of rubber.

[0047] In some examples, the area of ​​plate 111 is smaller than the area of ​​plate 212.

[0048] In actual use, part of the weight of the flat plate collector 2 presses on the plate 112. By making the plate 112 have a larger area, the pressure in the area where the back of the flat plate collector 2 contacts the plate 112 can be reduced, thereby preventing the back of the flat plate collector 2 from being crushed.

[0049] In some examples, the widths of plate 111, plate 212, and plate 313 are the same, and the length of plate 111 is less than the length of plate 212.

[0050] In actual processing, the U-shaped channel 11 can be prepared by bending metal plates of equal width, which is convenient for processing. Since the flat plate solar collector 2 is exposed to direct sunlight for a long time, if the U-shaped channel 11 is made of polymer materials such as plastic, it is prone to aging and cracking after a period of use, resulting in high maintenance costs. In this embodiment, the U-shaped channel 11 is preferably made of stainless steel to provide better resistance to sun and rain.

[0051] In some examples, connector 12 is L-shaped, including plate four 121 and plate five 122, which are vertically and fixedly connected. Plate four 121 is fitted and fixedly connected to plate two 112, and plate five 122 is perpendicular to plate three 113. Mounting hole 123 is located on plate five 122.

[0052] In actual manufacturing, the connector 12 can be made of metal, preferably stainless steel, to provide better resistance to sun and rain. The connector 12 can be fixedly connected to the U-shaped groove 11 by welding or by bolt and nut assembly.

[0053] For example, connector 12 can be obtained by cutting angle steel.

[0054] In some examples, plate 4 121 and plate 5 122 have the same width, but the length of plate 4 121 is less than the length of plate 5 122.

[0055] By making plate 5 122 longer, the distance between the mounting hole 123 on plate 5 122 and the U-shaped groove 11 can be increased, that is, the distance between the flat plate collector 2 and the installation position (e.g., upper support 4, lower support 6) can be increased, thereby avoiding the flat plate collector 2 from colliding with the installation position when it shakes.

[0056] In some examples, the width of plates 111, 112, and 113 is 30mm, the length of plate 111 is 40mm, the length of plate 212 is 80mm, and the length of plate 313 is 142mm. The width of plates 4121 and 122 is 50mm, the length of plate 4121 is 32mm, and the length of plate 5122 is 54mm. However, the actual implementation is not limited to these, and the appropriate dimensions can be selected according to the actual situation in actual use.

[0057] This embodiment also provides a flat plate solar collector assembly, including the windproof and reinforced structure 1 described above, as well as a flat plate solar collector 2, an upper fastening component 3, an upper support 4, a lower fastening component 5, and a lower support 6.

[0058] There are multiple windproof reinforcement structures 1, including upper reinforcement structures and lower reinforcement structures.

[0059] The upper end of the flat plate solar collector 2 is inserted into the U-shaped groove 11 of the upper reinforcing structure, and the lower end of the flat plate solar collector 2 is inserted into the U-shaped groove 11 of the lower reinforcing structure.

[0060] The upper fastening assembly 3 includes an upper bolt and an upper nut. The upper bolt passes through the mounting hole 123 of the upper reinforcement structure, the flat plate collector 2, and the upper support 4, and is locked by the upper nut.

[0061] The lower fastening assembly 5 includes a lower bolt and a lower nut. The lower bolt passes through the mounting hole 123 of the lower reinforcement structure, the flat plate collector 2, and the lower support 6, and is locked by the lower nut.

[0062] The working principle of the flat-plate solar collector assembly in this embodiment is as follows:

[0063] The line connecting the upper and lower ends of the flat plate solar collector 2 is along its own width direction. By setting an upper reinforcement structure at the upper end and a lower reinforcement structure at the lower end of the flat plate solar collector 2, the displacement of the flat plate solar collector 2 along its own thickness direction and its own width direction can be restricted, achieving multi-point limiting and enabling the flat plate solar collector 2 to maintain better stability.

[0064] For example, the number of both upper and lower reinforcing structures is preferably multiple. Each upper reinforcing structure corresponds to an upper support 4 and an upper fastening component 3, and each lower reinforcing structure corresponds to a lower support 6 and a lower fastening component 5.

[0065] In some examples, the connector 12 of the upper reinforcement structure is clamped between the upper nut and the upper support 4. The connector 12 of the lower reinforcement structure is clamped between the lower nut and the lower support 6.

[0066] By selecting this connection position, the upper reinforcement structure can be installed and removed without moving the upper bolt, and the lower reinforcement structure can be installed and removed without moving the lower bolt. It is only necessary to remove the upper nut and the lower nut during installation and removal.

[0067] It should be noted that since the upper and lower bolts bear the weight of the flat plate solar collector 2, removing them requires lifting the flat plate solar collector 2; otherwise, the frictional resistance will be extremely high. However, the flat plate solar collector 2 is quite heavy, making lifting it very difficult and potentially dangerous.

[0068] In this embodiment, by selecting to clamp the upper reinforcing structure connector 12 between the upper nut and the upper support 4, and clamp the lower reinforcing structure connector 12 between the lower nut and the lower support 6, the removal of the upper and lower bolts is avoided, as is raising the flat plate collector 2, which greatly improves the convenience and safety of operation.

[0069] In some examples, the upper fastening assembly 3 also includes an upper cotter pin, which is mounted on the thread of the upper bolt and located on the side of the upper nut away from the head of the upper bolt. The lower fastening assembly 5 also includes a lower cotter pin, which is mounted on the thread of the lower bolt and located on the side of the lower nut away from the head of the lower bolt.

[0070] The upper cotter pin, inserted into the threaded rod of the upper bolt, prevents the upper nut from falling off. Similarly, the lower cotter pin, inserted into the threaded rod of the lower bolt, prevents the lower nut from falling off. In practice, when it is necessary to remove the upper and lower nuts, the upper and lower cotter pins must be removed first.

[0071] In some examples, the upper support 4 includes a support rod and a mounting base one, with the lower end of the support rod fixedly connected to the mounting base one, and an upper bolt passing through the upper end of the support rod. The lower support 6 includes a mounting base two. Mounting base one and mounting base two have the same structure and are used to fix it to the ground.

[0072] Normally, mounting base one and mounting base two are set at the same height. By selecting the length of the support rod, the tilt angle of the flat plate collector 2 can be controlled.

[0073] Mounting bracket one and mounting bracket two are used to fix the object to the ground, where the ground can be... Figure 4 The cement block shown in the image.

[0074] In some examples, the back of the flat plate collector 2 has ribs extending along its own width direction, the ribs extending from the upper end to the lower end of the flat plate collector 2, the upper bolts passing through the upper end of the ribs, and the lower bolts passing through the lower end of the ribs.

[0075] The ribs not only enhance the strength of the flat plate solar collector 2, but also provide mounting positions for the upper and lower bolts.

[0076] In some examples, both mounting base one and mounting base two include a base plate and two upright plates. The lower ends of the two upright plates are vertically fixed to the upper surface of the base plate, and the two upright plates are positioned opposite each other. The support rod is a channel steel, with the two upright plates of mounting base one located inside the groove at the lower end of the channel steel, and the upper end of the rib located inside the groove at the upper end of the channel steel.

[0077] The upper bolt passes through the two side walls of the channel steel and the reinforcing rib between the two side walls. The lower bolt passes through the two upright plates of mounting base two. Mounting base one is also fixed to the channel steel by a fastening assembly whose bolts pass through the two side walls of the channel steel and the two upright plates of mounting base one located between the two side walls.

[0078] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
