Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic component brackets, and in particular to a bracket for a photovoltaic component. Background Art

[0002] Photovoltaic power generation refers to a power generation system that uses solar energy and adopts special materials such as silicon panels, inverters and other electronic components. It is connected to the power grid and transmits electricity to the power grid. Photovoltaic power generation is the green power development energy project that the country encourages most. Since the photovoltaic panels used in photovoltaic power generation require a large amount of space for laying, photovoltaic panels are generally laid in deserts, water surfaces, wastelands and rooftops.

[0003] However, most of the existing photovoltaic panels installed on the water surface are fixedly installed, and the angle of the photovoltaic panels cannot be adjusted according to seasonal changes in sunlight, and the utilization rate of sunlight is low. For example, the patent application document with the Chinese utility model publication number CN217864624U discloses a water surface photovoltaic bracket. Although the support structure can drive the photovoltaic component to rotate around the center of the arc-shaped guide structure by setting an arc-shaped guide structure, thereby adjusting the inclination angle of the photovoltaic component relative to the mounting portion, the adjustment angle is relatively limited, and it is difficult to make more flexible adjustments. Summary of the Invention

[0004] The purpose of the present invention is to solve the above-mentioned shortcomings in the prior art and to propose a bracket for photovoltaic modules.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A photovoltaic module support, comprising a double-glass photovoltaic panel and two parallel rotating shafts, both of which are controlled and driven by external driving equipment and rotate in opposite directions, and a buoy is provided on the outer rotating sleeve of the rotating shaft, and further comprising:

[0007] There are two rope drums, each of which is fixedly installed on the right side of the two rotating shafts. A rope is wound in a cross shape between the two rope drums. The end of the rope away from the rope drum is fixedly connected to a connector. Rubber belts are fixedly connected between the two sets of connectors above and between the two sets of connectors below.

[0008] A fixing rope is fixedly connected to the left side between the two buoys. Two groups of floating boards are arranged in parallel between the fixing rope and the two groups of rubber belts. The ends of the two groups of floating boards close to the fixing rope are fixedly connected to the fixing rope through rope buckles fixedly installed thereon. Belt buckles are fixedly installed on the upper and lower sides of the ends of the two groups of floating boards close to the rubber belts. The rubber belts pass through the corresponding belt buckles and are fixedly connected to them.

[0009] The support and adjustment mechanism is arranged on the two groups of floating plates and is used for fixing and installing the double-glass photovoltaic panels.

[0010] Preferably, the support adjustment mechanism includes two groups of connecting parts fixedly installed on the upper end of the floating plate on the front side and arranged symmetrically on the left and right, and two groups of spring bases fixedly installed on the upper end of the floating plate on the rear side and arranged symmetrically on the left and right. The working ends of the spring bases are installed with compression connecting parts, and the upper ends of the connecting parts and the compression connecting parts are rotatably installed with rotary joints, and a support assembly is arranged above the multiple groups of rotary joints.

[0011] Preferably, the support assembly includes a guide rail rod fixedly mounted on a rotary joint above the connecting member, a spring fixedly mounted on the upper end of the guide rail rod, an end of the spring away from the guide rail rod is fixedly connected to a slider slidably sleeved on the outside of the guide rail rod, and the lower surface of the slider is fixedly connected to the rotary joint provided on the compression connecting member.

[0012] Preferably, the lower ends of the two guide rods are fixedly connected to a fixing plate, and the upper surfaces of the two groups of sliders are fixedly installed with a limiting plate. The upper surface of the fixing plate and the upper surface of the limiting plate are both fixedly installed with two groups of fixing clips that are symmetrically arranged on the left and right.

[0013] Preferably, a fixing rod is fixedly installed between the spring base and the connecting member.

[0014] Preferably, a reflective assembly is also included, which includes a bevel gear fixedly installed at the middle position of the rotating shaft, and a rotating connector meshing with the bevel gear is provided above the bevel gear. The upper end of the rotating connector is rotatably installed with a rotating connector after rotating through the upper side wall of the float, and a reflective plate is fixedly installed on the end of the rotating connector away from the rotating connector.

[0015] Preferably, there is damping between the rotating connector and the swivel connector, and the two groups of reflectors are symmetrically distributed.

[0016] Preferably, a counterweight bin is fixedly mounted on the lower end surface of the floating plate, and a wave-breaking component is provided below the counterweight bin.

[0017] Preferably, the wave-breaking assembly includes two groups of wave-breaking plates fixedly mounted on the lower end surface of the counterweight bin and symmetrically distributed on the left and right sides. The wave-breaking plates are arranged in a wave shape and have multiple through holes evenly opened on the surface. The two wave-breaking plates are distributed in an "eight" shape.

[0018] Preferably, the wave-breaking plate is made of elastic material.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. Compared with the traditional fixing method of photovoltaic module bracket, the present invention is more stable and convenient for installation and disassembly. The connection between the components uses flexible connection to adapt to the ups and downs of the water surface, reduce stress concentration, and improve the reliability and durability of the connection.

[0021] 2. In the present application, by setting the rotating shaft, rope drum, rope and rubber belt, when the sun moves westward in the afternoon, the rotating shafts on both sides rotate outward at the same time. When the rotating shaft on the left rotates counterclockwise and the rotating shaft on the right rotates clockwise, the rope below can be reeled in. While reeling in, the rope gradually tightens and drives the rubber belt below to move upward. When the rubber belt moves upward, it drags the right end of the floating board upward, so that the floating board can rotate a certain angle around the fixed rope, which is convenient for adjusting the angle of the double-glass photovoltaic panel in the afternoon so that it can receive sunlight more fully.

[0022] 3. In this application, by setting up the reflector and adjusting the angle of the reflector, the reflection of the water surface and the reflector can be used to make the light more concentrated, and the light can be received efficiently throughout the day, which greatly improves the input of light energy, promotes the output of clean electric energy, protects the environment, reduces dependence on limited resources, and provides a sustainable supply of clean energy.

[0023] 4. In this application, through the arrangement of the counterweight bin and the wave-breaking plate, when the water body fluctuates greatly or the water flow accelerates due to severe weather, when the water flow collides with the wave-like concave and convex surface of the wave-breaking plate, part of the water flow passes through the holes in the wave-breaking plate and slows down the flow rate, and part of the water flow is buffered when rushing to the concave and convex part. At the same time, the water flow turns in the opposite direction after hitting the inner concave surface to form a reaction force, which weakens the impact of the water flow, keeps the water surface stable, reduces large fluctuations of the water surface, and prevents the water equipment from being damaged due to excessive fluctuations of the water surface; when the weather is clear, the wave-breaking plate reduces the impact of underwater water flow on the water surface, reduces water surface fluctuations, keeps the water surface stable, and enhances the reflective effect of the water surface.

[0024] In summary, the present application can effectively ensure the power generation of the photovoltaic panel through the setting of the above-mentioned structure on the one hand, and on the other hand, can also effectively ensure the stability of the photovoltaic panel during operation.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Reference Figures 1 to 7 , a bracket for photovoltaic components, including two parallel rotating shafts 8, the rotating shaft 8 is controlled and driven by an external driving device, and a buoy 7 is provided on the outer side of the rotating shaft 8. A bevel gear 9 is fixedly installed at the middle position of the rotating shaft 8, and a rotating connector 25 meshing with it is provided above the bevel gear 9. The upper end of the rotating connector 25 is rotatably installed with a rotating connector after rotating through the upper side wall of the buoy 7. There is a large damping between the rotating connector and the rotating connector 25, and a reflector 26 is fixedly installed on the end of the rotating connector away from the rotating connector 25. Before the device is used, the staff can manually adjust the angle of the reflector 26. Due to the existence of damping, in the absence of staff intervention, the reflector 26 is difficult to rotate around the rotating connector by itself under the interference of external factors.

[0035] A fixed rope 6 is fixedly connected to the left side between the two buoys 7, and a rope drum 10 is fixedly installed on the right side of the two rotating shafts 8. A rope 13 is wound in a cross shape between the two rope drums 10, and a connecting piece 12 is fixedly connected to the end of the rope 13 away from the rope drum 10. A rubber belt 11 is fixedly connected between the two upper groups of connecting pieces 12 and between the two lower groups of connecting pieces 12. The two groups of rubber belts 11 are arranged in parallel. Two groups of floating boards 1 distributed in parallel are arranged between the fixed rope 6 and the two groups of rubber belts 11. The ends of the two groups of floating boards 1 close to the fixed rope 6 are fixedly connected to the fixed rope 6 through the rope buckle 4. Belt buckles 5 are fixedly installed on the upper and lower sides of the ends of the two groups of floating boards 1 close to the rubber belt 11. The rubber belt 11 passes through the belt buckle 5 and is fixedly connected to the belt buckle 5.

[0036] When the left rotating shaft 8 rotates counterclockwise and the right rotating shaft 8 rotates clockwise, the rope 13 below can be reeled in. While reeling in, the rope 13 gradually tightens and drives the rubber belt 11 below to move upward. While the rubber belt 11 moves upward, it drags the right end of the floating board 1 upward, so that the floating board 1 can rotate a certain angle around the fixed rope 6, which is convenient for adjusting the angle of the double-glass photovoltaic panel 27 in the afternoon so that it can receive sunlight more fully.

[0037] Two groups of connecting parts 15 are fixedly installed on the upper end of the floating board 1 on the front side, and two groups of spring bases 14 are fixedly installed on the upper end of the floating board 1 on the rear side. A compression connecting part 17 is installed on the working end of the spring base 14. The upper ends of the connecting part 15 and the compression connecting part 17 are rotatably installed with a rotary joint 18. The upper end of the rotary joint 18 above the connecting part 15 is fixedly installed with a guide rail rod 19. The lower ends of the two guide rail rods 19 are jointly fixedly connected to a fixing plate 22. Two groups of fixing clips 24 are fixedly installed on the upper surface of the fixing plate 22. A spring 20 is fixedly installed on the upper end of the guide rail rod 19. The end of the spring 20 away from the guide rail rod 19 is fixedly connected to a slider 21 slidably sleeved on the outside of the guide rail rod 19. The lower surface of the slider 21 is fixedly connected to the rotary joint 18 provided on the compression connecting part 17. A limit plate 23 is fixedly mounted on the upper surfaces of the two sets of sliders 21 , and two sets of fixing clips 24 symmetrically arranged on the upper surface of the limit plate 23 are fixedly mounted.

[0038] When the double-glass photovoltaic panel 27 needs to be fixed and installed, the lower end of the double-glass photovoltaic panel 27 can be placed in the two fixing clamps 24 at the bottom first, and then the limit plate 23 is pulled upward to drive the two fixing clamps 24 at the top to move upward, so that the double-glass photovoltaic panel 27 is placed flat on the upper surface of the guide rod 19. Finally, the limit plate 23 is released to allow the limit plate 23 to drive the fixing clamp 24 to move downward, so that the upper end of the double-glass photovoltaic panel 27 can be clamped and fixed.

[0039] To enhance the stability of the device, the spring base 14 and the connector 15 are fixedly connected by a fixing rod 16. A counterweight bin 2 is fixedly mounted on the lower surface of the floating board 1. Two sets of wave-breaking plates 3 are fixedly mounted on the lower surface of the counterweight bin 2 in a bilaterally symmetrical arrangement. The wave-breaking plates 3 are arranged in a wave shape and have multiple through holes evenly distributed on their surfaces. The two wave-breaking plates 3 are arranged in an "eight" shape.

[0040] When the water body fluctuates greatly or the water flow accelerates due to bad weather, when the water flow collides with the wavy concave and convex surface of the wave-breaking plate 3, part of the water flow slows down after passing through the holes in the wave-breaking plate 3, and part of the water flow is buffered when rushing to the concave and convex part. At the same time, the water flow turns in the opposite direction after hitting the inner concave surface to form a reaction force, which weakens the impact of the water flow, keeps the water surface stable, reduces large fluctuations of the water surface, and prevents the water equipment from being damaged due to excessive fluctuations of the water surface; when the weather is clear, the wave-breaking plate 3 reduces the impact of underwater water flow on the water surface, reduces water surface fluctuations, keeps the water surface stable, enhances the reflective effect of the water surface, and enables the back of the double-glass photovoltaic panel 27 to receive more reflected light, thereby improving the energy conversion efficiency.

[0041] The specific working principle of the present invention is as follows: when installing the double-glass photovoltaic panel 27, the lower end of the double-glass photovoltaic panel 27 is placed on the fixing clip 24 above the fixing plate 22, and the back of the double-glass photovoltaic panel 27 is placed on the guide rod 19. Under the action of gravity, the connecting piece 15 and the rotating joint 18 connected to it rotate relative to each other, and the slider 21 slides down to compress the spring 20. The rotating joint 18 on the lower side of the slider 21 and the compression connecting piece 17 rotate relative to each other, and the compression connecting piece 17 compresses the spring base 14 downward, and the slider 21 drives the fixing clip 24 above the limit plate 23 to clamp downward to fix the upper end of the double-glass photovoltaic panel 27, strengthening the fixation of the double-glass photovoltaic panel 27 while reducing the workload of installing the double-glass photovoltaic panel 27, and also facilitating the subsequent disassembly and maintenance work. The spring base 14 and the connecting piece 15 are connected by a fixing rod 16 and fixed to the floating board 1, making the upper device more stable.

[0042] A counterweight tank 2 is installed under the floating board 1, which is used to adjust the draft depth of the entire device. There are two wave-breaking plates 3 inserted into the water on the lower side of the counterweight tank 2. When the water body fluctuates greatly or the water flow accelerates due to bad weather, when the water flow collides with the wavy concave and convex surface of the wave-breaking plate 3, part of the water flow passes through the holes in the wave-breaking plate 3 and slows down the flow rate, and part of the water flow is buffered when rushing to the concave and convex part. At the same time, the water flow turns in the opposite direction after hitting the inner concave surface to form a reaction force, which weakens the impact of the water flow, keeps the water surface stable, reduces large fluctuations in the water surface, and prevents the water device from being damaged due to excessive fluctuations in the water surface; when the weather is clear, the wave-breaking plate 3 reduces the impact of underwater water flow on the water surface, reduces water surface fluctuations, keeps the water surface stable, enhances the reflection effect of the water surface, and makes the back of the double-glass photovoltaic panel 27 receive more reflected light, thereby improving the energy conversion efficiency.

[0043] When the sunlight intensity is the highest at noon, the sun is directly above the double-glass photovoltaic panel 27. At this time, the reflector 26 is parallel to the buoy 7 below. The sunlight hits the plane of the reflector 26 and is refracted to the front and back sides of the double-glass photovoltaic panel 27, increasing the utilization rate of light and further improving the energy conversion efficiency.

[0044] In the afternoon, the sun moves westward, and the shafts 8 on both sides rotate outward at the same time. The bevel gear 9 on the shaft 8 drives the rotating connector 25 to rotate, and the rotating connector on the rotating connector 25 drives the reflector 26 to deflect. The reflector 26 facing the double-glass photovoltaic panel 27 deflects counterclockwise, and the reflector 26 facing the back of the double-glass photovoltaic panel 27 deflects clockwise. The shaft 8 drives the rope drum 10 to rotate, and the waterproof rope 13 is wound around the upper side of the rope drum 10 to collect the rope, driving the waterproof rubber belt 11 connected to the lower side through the connector 12 to move upward. At the same time, the rope 13 and the lower side of the rope drum 10 are wound around the rope drum 10. A rope is released at the side winding point, driving the rubber belt 11 connected to the upper side through the connector 12 to move upward. A waterproof fixing rope 6 is passed through the rope buckle 4 on the left side of the floating board 1. Both ends of the fixing rope 6 are fixed on the buoy 7 to fix the left side of the floating board 1. The belt buckle 5 on the right side prevents the rubber belt 11 from shifting while assisting the right side of the floating board 1 to move upward smoothly. The double-glass photovoltaic panel 27 at the upper end is offset to the left, facing the direction of the sun's movement to receive more light. At the same time, the offset of the reflectors 26 on both sides is also towards the direction of the sun's movement, further increasing the reflected light and achieving high-efficiency light reception all day long.

[0045] At night, the two side shafts 8 rotate inwards at the same time, driving the double-glass photovoltaic panel 27 and the reflective plate 26 to the right (towards the east), so that they can receive light as soon as the sun rises in the morning.

[0046] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
