A photovoltaic cable frame

Abstract

This invention belongs to the field of photovoltaic technology and discloses a photovoltaic cable frame, including a base, with support frames fixedly installed at the left and right ends of the top of the base. This invention achieves good wind resistance by incorporating a rake, impeller, and swing rod. When encountering strong winds, the current in the electromagnet at one end of the photovoltaic cable frame gradually increases during the movement of the slider, and the magnetic force of the electromagnet gradually increases. Under the action of the magnetic force, the transmission block moves downward, driving one end of the swing rod downward, while the other end of the swing rod moves upward. At this time, one end of the rope moves downward, and the other end moves upward, causing the windward side of the photovoltaic panel to move downward. This results in the photovoltaic panel installed at the top of the rope tilting at a 30-degree angle, thereby reducing wind resistance and effectively preventing the wind from pushing the bottom of the photovoltaic panel and causing it to swing, thus achieving good wind resistance for the cable frame.

Description

Technical Field

[0001] This invention belongs to the field of photovoltaic technology, specifically a photovoltaic cable frame. Background Technology

[0002] Photovoltaics, or photovoltaic power generation systems, are power generation systems that utilize the photovoltaic effect of semiconductor materials to convert solar radiation energy into electrical energy. The energy of photovoltaic power generation systems comes from inexhaustible solar energy, making it a clean, safe, and renewable energy source. The photovoltaic power generation process does not pollute the environment or damage the ecosystem. With the vigorous development of the photovoltaic industry, land and rooftop resources are gradually decreasing. Many hilly areas, deep fishponds, mudflats with poor geological conditions, and large-span water plants are not fully utilized due to limitations imposed by traditional photovoltaic support installation methods. Photovoltaic cable-stayed systems, also known as flexible photovoltaic supports, employ a "suspension, tension, hanging, support, and pressure" process, effectively avoiding unfavorable factors such as undulating terrain and high vegetation cover, turning previously unusable land into valuable resources and greatly improving land utilization. This invention's cable-stayed system is specifically designed for hilly areas.

[0003] Currently, photovoltaic cable-stayed structures consist of support frames and ropes. The ropes support the photovoltaic modules and effectively avoid terrain such as hills, ponds, or large-span swamps, thereby improving land utilization. However, because the photovoltaic panels are supported by ropes with large spans, the ropes have poor stability. In addition, strong outdoor winds cause the photovoltaic cable-stayed structures to sway significantly, directly affecting the stability of the photovoltaic panels and posing certain safety hazards, which in turn affects the power generation of the photovoltaic panels. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the problems mentioned in the background section, this invention provides a photovoltaic cable frame that solves the problem of large swing amplitude caused by strong outdoor winds, which affects the stability of the photovoltaic panels and consequently their power generation. The cable frame has the advantage of being wind-resistant.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic cable frame, comprising a base, support frames fixedly installed at the left and right ends of the top of the base, a fixing rod fixedly installed on the inner side of the top of the support frame, a fixing frame fixedly installed on the inner side of the support frame at the bottom of the fixing rod, a wind-resistant component movably installed on the front of the fixing frame, a tightening component fixedly installed on the back of the support frame, a transmission component fixedly installed on the inner side of the support frame, guide grooves respectively opened at the upper end of the support frame, and fixing components fixedly installed at the left and right ends of the wind-resistant component;

[0008] The wind-resistant component includes a swing rod, the left and right ends of which are movably engaged with the inside of the guide groove. Each of the left and right ends of the swing rod has a locking groove, and a locking block is slidably engaged inside the locking groove. A transmission block is fixedly installed at the bottom of each locking block, and a first spring is fixedly installed at the bottom of each transmission block. An electromagnet is fixedly installed at the bottom of the first spring.

[0009] In windy weather, the wind will cause the impeller to rotate, which in turn drives the rifled rod to rotate. During this rotation, the electromagnets at both ends of the rifled rod will be energized. Simultaneously, because the electromagnets are connected in parallel with the slider, the drive ring moves against the wind through the threaded groove on the outside of the rifled rod. Since the damping between the drive ring and the sleeve is greater than the weight of the slider itself, the drive ring drives the sleeve, slider, and limit block to move. The slider slides outside the resistance wire. During this movement, the current in one electromagnet will gradually increase, and the magnetic force of the electromagnet will gradually increase. Under the influence of the magnetic force, the resistance wire... The transmission block moves downward and compresses the first spring. At the same time, the locking block slides inside the locking groove and drives one end of the swing rod downward, while the other end of the swing rod moves upward. Since the ropes are fixedly installed at the left and right ends of the swing rod, one end of the rope moves downward and the other end moves upward, causing the windward side of the photovoltaic panel to move downward. This causes the photovoltaic panel installed at the top of the rope to tilt at a 30-degree angle, allowing the wind to blow through the top of the photovoltaic panel. This effectively prevents the wind from pushing the bottom of the photovoltaic panel, causing the photovoltaic panel and rope to sway, thereby improving the wind resistance of the photovoltaic panel.

Impellers are fixedly installed on the left and right sides of the firing rod, and protective frames are fixedly installed on the left and right sides of the support frame outside the impellers.

A counterweight is fixedly installed at one end of the rope. A fourth spring is fixedly installed at the bottom of the movable block.

[0013] Preferably, the middle part of the swing rod is movably installed with the middle part of the fixed frame, the left and right ends of the swing rod are respectively movably engaged with the inside of the guide groove, the transmission block is movably engaged with the inside of the guide groove, the electromagnet is fixedly installed with the bottom of the guide groove, the electromagnet is connected in parallel with the slider, and the transmission block is made of iron.

[0014] Preferably, the outside of the rifle rod is provided with a threaded groove, the transmission ring is threadedly sleeved on the outside of the rifle rod, the sleeve is movably sleeved on the outside of the transmission ring, the damping between the sleeve and the transmission ring is greater than the resistance of the slider movement, and the limiting block is movably engaged inside the limiting rod.

[0015] Preferably, the resistance of the resistance wire increases from the middle to both ends, and the slider is movably sleeved on the outside of the resistance wire.

[0016] Preferably, the fixing block has a circular groove inside, and the inner diameter of one end of the circular groove gradually decreases from left to right, and the first collar is movably sleeved inside the circular groove.

[0017] Preferably, the inner diameter of the first collar is the same as the outer diameter of the rope in the tightening assembly, the rope in the tightening assembly moves through the inside of the first collar, and the first fixing ball is movably engaged with the outside of the first collar and contacts the outside of the rope in the tightening assembly.

[0018] Preferably, the movable blocks are slidably engaged with the interior of the limiting frame, the rope moves through the interior of the second collar, the exterior of the second fixed ball contacts the exterior of the rope, and the elastic coefficient of the fourth spring is greater than the magnetic force of the electromagnet.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] This invention achieves good wind resistance for the cable frame by incorporating a joist, impeller, and swing rod. When encountering strong winds, the wind drives the impeller to rotate, which in turn rotates the joist. During rotation, the electromagnets at both ends of the joist are energized, causing the sleeve, slider, and limit block to move via the joist, transmission ring, and limit block. As the slider moves, the current in one electromagnet gradually increases, and the magnetic force of the electromagnet also gradually increases. Under the influence of the magnetic force, the transmission block moves downward, causing one end of the swing rod to move downward while the other end moves upward. This causes one end of the rope to move downward while the other end moves upward, moving the windward side of the photovoltaic panel downward. This results in the photovoltaic panel installed at the top of the rope tilting at a 30-degree angle, reducing wind resistance and effectively preventing the wind from pushing the bottom of the photovoltaic panel and causing it to swing, thus achieving good wind resistance for the cable frame.

[0022] This invention achieves the purpose of cleaning photovoltaic panels by incorporating an electromagnet, a first spring, and a rope. As the wind blows and the impeller rotates, the current in the electromagnet at one end gradually increases, and the magnetic force of the electromagnet gradually increases. Under the action of the magnetic force, one end of the swing rod is pulled downwards, simultaneously moving the rope at one end downwards. This causes the photovoltaic panel at the top of the rope to tilt at a 30-degree angle, increasing the contact area between the top of the photovoltaic panel and the wind. The wind then cleans the top of the photovoltaic panel, reducing dust accumulation and thus increasing the power generation of the photovoltaic panel, achieving the desired cleaning effect.

[0023] This invention achieves rope tightening by incorporating a counterweight, a second collar, and a second fixed ball. As the swing rod moves downwards, the rope passes through the first and second collars. The swing rod drives a fixed block at one end downwards, creating a drop between the fixed and movable blocks. During this movement, the fixed block secures one end of the rope via the second collar and the second fixed ball. The fixed block then pulls the other end of the rope, causing it to enter the space between the movable and fixed blocks. When the wind stops, the swing rod returns to its original position, moves upwards, and reaches a horizontal position. A second spring pushes the first collar to compress the first fixed ball, securing the other end of the rope. At this point, the rope between the movable and fixed blocks, under the influence of the counterweight, pushes the second collar and the third spring, causing the rope to move to the left, thus tightening the rope and achieving the desired tightening effect.

Detailed Implementation

[0034] 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.

[0035] like Figures 1 to 9As shown, the present invention provides a photovoltaic cable frame, including a base 1, support frames 2 are fixedly installed at the left and right ends of the top of the base 1, a fixing rod 6 is fixedly installed on the inner side of the top of the support frame 2, a fixing frame 7 is fixedly installed on the inner side of the support frame 2 at the bottom of the fixing rod 6, a wind-resistant component 8 is movably installed on the front of the fixing frame 7, a tightening component 5 is fixedly installed on the back of the support frame 2, a transmission component 3 is fixedly installed on the inner side of the support frame 2, guide grooves 9 are respectively opened at the upper end of the support frame 2, and fixing components 11 are fixedly installed at the left and right ends of the wind-resistant component 8.

[0036] The wind-resistant component 8 includes a swing rod 801. The left and right ends of the swing rod 801 are movably engaged with the inside of the guide groove 9. The left and right ends of the swing rod 801 are respectively provided with engagement grooves 802. Engagement blocks 803 are slidably engaged inside the engagement grooves 802. Transmission blocks 804 are fixedly installed at the bottom of the engagement blocks 803. A first spring 805 is fixedly installed at the bottom of the transmission blocks 804. An electromagnet 806 is fixedly installed at the bottom of the first spring 805.

[0037] The transmission assembly 3 includes a bolt 303, which is movably installed inside the support frame 2. Impellers 302 are fixedly installed on the left and right sides of the bolt 303, respectively. Protective frames 301 are fixedly installed on the left and right sides of the support frame 2 outside the impellers 302. A resistance wire 304 is fixedly installed on the top of the bolt 303 inside the support frame 2. A limit rod 309 is fixedly installed on the back of the resistance wire 304 inside the support frame 2. A slider 308 is movably sleeved on the outside of the resistance wire 304. A limit block 307 is fixedly installed on the back of the slider 308. A sleeve 306 is fixedly installed on the bottom of the slider 308. A transmission ring 305 is movably sleeved inside the sleeve 306.

[0038] Using the above scheme: by installing two bases 1 at the top and bottom of the hill respectively, and connecting two ropes 503 between the two bases 1 respectively, with the ropes 503 located at the left and right ends of the swing rod 801 respectively, the photovoltaic panel can be installed on the top of the ropes 503.

[0039] In windy weather, the wind will cause the impeller 302 to rotate, which in turn will drive the crankshaft 303 to rotate. During the rotation of the crankshaft 303, the electromagnets 806 at both ends will be energized. Simultaneously, since the electromagnets 806 and the slider 308 are connected in parallel, the drive ring 305 moves against the wind through the threaded groove on the outside of the crankshaft 303. Because the damping between the drive ring 305 and the sleeve 306 is greater than the weight of the slider 308 itself, the drive ring 305 drives the sleeve 306, the slider 308, and the limiting block 307 to move. The slider 308 slides outside the resistance wire 304. During the movement of the slider 308, the current in one end of the electromagnet 806 will gradually increase, and the magnetic force of the electromagnet 806 will gradually increase. As the magnetic force gradually increases, the transmission block 804 moves downward and squeezes the first spring 805 under the action of the magnetic force. At the same time, the locking block 803 slides inside the locking groove 802 and drives one end of the swing rod 801 to move downward, while the other end of the swing rod 801 moves upward. Since the ropes 503 are fixedly installed at the left and right ends of the swing rod 801 respectively, at this time one end of the rope 503 moves downward and the other end moves upward, causing the windward side of the photovoltaic panel to move downward, so that the photovoltaic panel installed at the top of the rope 503 is tilted at 30 degrees, allowing the wind to blow through the top of the photovoltaic panel, effectively preventing the wind from pushing the bottom of the photovoltaic panel and causing the photovoltaic panel and rope 503 to sway, thereby improving the wind resistance of the photovoltaic panel.

[0040] Meanwhile, when the photovoltaic panel at the top of the rope 503 is tilted at a 30-degree angle, the contact area between the top of the photovoltaic panel and the wind is increased. The wind blows the top of the photovoltaic panel to clean it, reducing dust on the top of the photovoltaic panel and thus increasing the power generation of the photovoltaic panel.

[0041] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 9 As shown, the fixing component 11 includes a fixing block 111, which is fixedly installed on the left and right ends of the swing rod 801. The fixing block 111 is movably sleeved with a first collar 112, and the outer side of the first collar 112 is movably engaged with a first fixing ball 113 at an equal angle. A second spring 114 is fixedly installed on one side of the first collar 112.

[0042] The tightening assembly 5 includes a limiting frame 501, which is fixedly installed on the back of the support frame 2. Sliding grooves 504 are respectively opened at the left and right ends of the back of the limiting frame 501. A movable block 506 is movably engaged inside the limiting frame 501. A second collar 507 is movably sleeved inside the movable block 506. A third spring 508 is fixedly installed on one side of the second collar 507. A second fixed ball 505 is movably engaged at an equal angle on the outside of the second collar 507. A rope 503 is movably sleeved inside the second collar 507. A counterweight 502 is fixedly installed at one end of the rope 503. A fourth spring 509 is fixedly installed at the bottom of the movable block 506.

[0043] Using the above scheme: During the downward movement of the swing rod 801, since the rope 503 passes through the inside of the first collar 112 and the second collar 507 respectively, the swing rod 801 drives the fixed block 111 at one end to move downward, and a drop will be formed between the fixed block 111 and the movable block 506. Since the elastic coefficient of the fourth spring 509 is greater than the downward pulling force of the swing rod 801, during the movement of the fixed block 111, one end of the rope 503 is fixed by the second collar 507 and the second fixed ball 505. The fixed block 111 will pull the rope 503 at the other end, and the rope 503 will push the first collar 112 to the left and squeeze the second spring 114. At the same time, the inner side of the first fixed ball 113 will detach from the outside of the rope 503, so that the rope 503 enters between the movable block 506 and the fixed block 111, thereby tightening the rope 503.

[0044] When the wind stops, the swing arm 801 will reset, move upward, and be in a horizontal state. The second spring 114 pushes the first collar 112 to squeeze the first fixed ball 113 and fix the other end of the rope 503. At this time, the rope 503 between the movable block 506 and the fixed block 111 is affected by the gravity of the counterweight 502, which will push the second collar 507 and the third spring 508 to move the rope 503 to the left, thereby tightening the rope 503 and keeping the rope 503 in a taut state, thus improving the stability of the rope 503.

[0045] like Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the middle part of the swing rod 801 is movably installed with the middle part of the fixed frame 7. The left and right ends of the swing rod 801 are respectively movably engaged with the inside of the guide groove 9. The transmission block 804 is movably engaged with the inside of the guide groove 9. The electromagnet 806 is fixedly installed with the bottom of the guide groove 9. The electromagnet 806 is connected in parallel with the slider 308. The transmission block 804 is made of iron.

[0046] The outside of the rocker arm 303 is provided with a threaded groove. The transmission ring 305 is threadedly sleeved on the outside of the rocker arm 303. The sleeve 306 is movably sleeved on the outside of the transmission ring 305. The damping between the sleeve 306 and the transmission ring 305 is greater than the resistance of the slider 308. The limiting block 307 is movably engaged inside the limiting rod 309. The resistance value of the resistance wire 304 increases from the middle to the left and right ends. The slider 308 is movably sleeved on the outside of the resistance wire 304.

[0047] Using the above scheme: When the photovoltaic cable frame encounters strong winds, the wind will cause the impeller 302 to rotate. At this time, the two electromagnets 806 will be energized. Simultaneously, since the electromagnets 806 and the slider 308 are connected in parallel, they drive the transmission ring 305 to move against the wind through the threaded groove on the outside of the crankshaft 303. Because the damping between the transmission ring 305 and the sleeve 306 is greater than the weight of the slider 308 itself, the transmission ring 305 drives the sleeve 306, the slider 308, and the limiting block 307 to move. The slider 308 slides outside the resistance wire 304. During the movement of block 308, the current of one end of electromagnet 806 will gradually increase, and the magnetic force of electromagnet 806 will gradually increase. Under the action of the magnetic force, the transmission block 804 will move downward and squeeze the first spring 805. At the same time, when the transmission block 804 slides downward into the inside of the guide groove 9, the locking block 803 will slide into the inside of the locking groove 802 and pull down one end of the swing rod 801. Thus, the swing rod 801 pulls down one end of the rope 503, thereby causing the photovoltaic panel at the top of the rope 503 to tilt at a 30-degree angle.

[0048] At the same time, when the slider 308 moves to one end of the resistance wire 304, the limiting rod 309 limits the limiting block 307. When the slider 308 and the sleeve 306 are subjected to resistance, and the resistance is greater than the damping between the sleeve 306 and the transmission ring 305, the transmission ring 305 will rotate, thus keeping the swing rod 801 tilted at 30 degrees.

[0049] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 9 As shown, a circular groove is provided inside the fixing block 111, and the inner diameter of one end of the circular groove gradually decreases from left to right. The first collar 112 is movably sleeved inside the circular groove. The inner diameter of the first collar 112 is consistent with the outer diameter of the rope 503 in the tightening assembly 5. The rope 503 in the tightening assembly 5 moves through the inside of the first collar 112. The first fixing ball 113 is movably engaged with the outside of the first collar 112 and contacts the outside of the rope 503 in the tightening assembly 5.

[0050] The movable block 506 is slidably engaged with the inside of the limiting frame 501, the rope 503 is movably passed through the inside of the second ring 507, the outside of the second fixed ball 505 is in contact with the outside of the rope 503, and the elastic coefficient of the fourth spring 509 is greater than the magnetic force of the electromagnet 806.

[0051] Using the above scheme: During the downward movement of the swing rod 801, since the rope 503 passes through the inside of the first collar 112 and the second collar 507 respectively, the swing rod 801 drives the fixed block 111 at one end to move downward, creating a drop between the fixed block 111 and the movable block 506. Because the elastic coefficient of the fourth spring 509 is greater than the downward pulling force of the swing rod 801, the fixed block 111, during its movement, fixes one end of the rope 503 through the second collar 507 and the second fixed ball 505. The fixed block 111 will pull the other end of the rope 503, which will push the first collar 112 to the left and compress the second spring 114. At the same time, the inner side of the first fixed ball 113 will detach from the outside of the rope 503, allowing the rope 503 to enter between the movable block 506 and the fixed block 111. This tightens the rope 503. When the wind stops, the swing rod 801 will reset, move upward, and be in a horizontal state. The second spring 114 pushes the first collar 112 to squeeze the first fixed ball 113 and fix the other end of the rope 503. At this time, the rope 503 between the movable block 506 and the fixed block 111 is affected by the gravity of the counterweight block 502, which will push the second collar 507 and the third spring 508 to move the rope 503 to the left, thereby tightening the rope 503. At the same time, when one end of the swing rod 801 moves downward, the rope 503 will be in a taut state. At this time, the swing rod 801 pulls the movable block 506 downward through the rope 503 and compresses the fourth spring 509, so that the rope 503 is in a taut state and tilts normally.

[0052] Working principle and usage process of this invention:

[0053] When erecting a photovoltaic cable frame on a hill, the base 1 is first installed in a suitable position and fixed. At the same time, two ropes 503 are respectively passed through the inside of the first ring 112 and the second ring 507, and the ropes 503 are located at the left and right ends of the swing rod 801. One end of the rope 503 is fixedly connected to the counterweight 502, and the rope 503 is tightened, so that the photovoltaic panel can be installed on the top of the rope 503.

[0054] When the photovoltaic cable frame encounters strong winds, the wind will cause the impeller 302 to rotate, which in turn drives the relief rod 303 to rotate. During the rotation of the relief rod 303, the electromagnets 806 at both ends will be energized. Simultaneously, since the electromagnets 806 are connected in parallel with the slider 308, the drive ring 305 moves against the wind through the threaded groove on the outside of the relief rod 303. Because the damping between the drive ring 305 and the sleeve 306 is greater than the weight of the slider 308 itself, the drive ring 305 drives the sleeve 306, the slider 308, and the limiting block 307 to move. The slider 308 slides outside the resistance wire 304. During the movement of the slider 308, the current in one end of the electromagnet 806 will gradually increase. As the magnetic force of the electromagnet 806 increases, the transmission block 804 moves downward and squeezes the first spring 805. At the same time, the locking block 803 slides inside the locking groove 802 and drives one end of the swing rod 801 downward, while the other end of the swing rod 801 moves upward. Since the ropes 503 are fixedly installed at the left and right ends of the swing rod 801, one end of the rope 503 moves downward and the other end moves upward, causing the windward side of the photovoltaic panel to move downward. This causes the photovoltaic panel installed at the top of the rope 503 to tilt at a 30-degree angle, thereby reducing wind resistance and effectively preventing the wind from pushing the bottom of the photovoltaic panel and causing it to swing.

[0055] As the swing rod 801 moves downward, the rope 503 passes through the first collar 112 and the second collar 507 respectively. The swing rod 801 drives the fixed block 111 at one end to move downward, creating a drop between the fixed block 111 and the movable block 506. Because the elastic coefficient of the fourth spring 509 is greater than the downward pulling force of the swing rod 801, the fixed block 111, during its movement, fixes one end of the rope 503 through the second collar 507 and the second fixed ball 505. The fixed block 111 then pulls the rope 503 at the other end, which in turn pushes the first collar 112 to the left and compresses the second spring 114. At the same time, the inner side of the first fixed ball 113 will detach from the outside of the rope 503, allowing the rope 503 to enter between the movable block 506 and the fixed block 111, thereby tightening the rope 503. When the wind stops, the swing rod 801 will reset, move upward, and be in a horizontal state. The second spring 114 pushes the first collar 112 to squeeze the first fixed ball 113 and fix the other end of the rope 503. At this time, the rope 503 between the movable block 506 and the fixed block 111 is affected by the gravity of the counterweight 502, which will push the second collar 507 and the third spring 508 to move the rope 503 to the left, thereby tightening the rope 503.

[0056] At the same time, when one end of the swing rod 801 moves downward, and the rope 503 is in a taut state, the swing rod 801 pulls the movable block 506 downward through the rope 503 and compresses the fourth spring 509, so that the rope 503 is in a taut state and the rope 503 tilts normally.

[0057] When the slider 308 moves to one end of the resistance wire 304, the limiting rod 309 limits the limiting block 307. When the slider 308 and the sleeve 306 are subjected to resistance, and the resistance is greater than the damping between the sleeve 306 and the transmission ring 305, the transmission ring 305 will rotate. When the wind direction changes, the impeller 302 will rotate in the opposite direction, and will drive the transmission ring 305, the sleeve 306, the limiting block 307 and the slider 308 to rotate in the opposite direction respectively. Thus, the magnetic force of the electromagnet 806 at the other end pulls the swing rod 801 down, and drives the rope 503 at the other end respectively, so that the photovoltaic panel at the top of the rope 503 tilts in the opposite direction, thereby achieving the purpose of wind resistance.
