Description

Technical Field

[0001] The present invention relates to the field of photovoltaic technology, and in particular to a photovoltaic power generation device. Background Art

[0002] Photovoltaic panels are devices that use semiconductor materials to convert light into electricity. They are generally composed of multiple photovoltaic cells. Photovoltaic panels are mainly composed of solar cells, protection panels, brackets, junction boxes, inverters and other components. They absorb solar radiation through the panels to generate current, which is converted into alternating current through the inverter to supply power to homes and businesses. Photovoltaic panels can be widely used in various occasions.

[0003] In order to improve the utilization rate of light energy by photovoltaic panels and avoid obstruction, the existing technology usually installs photovoltaic panels in a higher position, such as the roof. However, it is well known that when it is windy, the wind is stronger at high places, so photovoltaic panels are easily disturbed by external wind force, resulting in the phenomenon of bracket tipping or damage. Although the problem of bracket tipping can be solved by fixing the photovoltaic panel bracket to the floor of the top floor with bolts or pins, this method not only requires drilling holes in the floor, but also cannot reduce the force of strong wind on the photovoltaic panel body, and the photovoltaic panel will still be damaged.

[0004] For example, the patent document with announcement number CN220896593U discloses a photovoltaic panel wind-resistant reinforcement device. Through the setting of the support frame and the adjustment component, when the external wind force changes, the personnel can pull the adjustment rod to drive the slide rod to slide inside the slide, so that the connecting block drives the card block to move inside the slide rails on both sides of the support column. When the card block moves to the appropriate position, the connecting bolt is placed in the connecting hole and the corresponding circular hole, and the connecting bolt is turned to fix it to form a triangular stable support. The personnel can adjust its force area according to the external wind force.

[0005] It can be seen that although the existing technology has solved the problem of the instability of the photovoltaic panel support frame when encountering strong winds, it still requires manual operation, which not only poses certain risks, but also has a relatively cumbersome operation process. Most importantly, it still cannot reduce the force of strong winds on the photovoltaic panel body. Summary of the invention

[0019] Wherein, the first cavity is connected to the oil delivery mechanism.

[0020] Preferably, the oil delivery mechanism includes an oil storage cylinder fixedly arranged on one side of the lifting cylinder, a second cavity is opened in the oil storage cylinder, one side of the bottom of the second cavity is connected with the first cavity through an oil inlet pipe, a one-way valve limited to oil inlet is provided between the oil inlet pipe and the second cavity, the other side of the bottom of the second cavity is connected with the first cavity through an oil outlet pipe, a one-way valve limited to oil discharge is provided between the oil outlet pipe and the second cavity, and the top of the second cavity is connected to the pumping mechanism for extracting the hydraulic oil in the second cavity.

[0023] Preferably, several groups of adsorption plates are evenly arranged on both sides of the base, a suction cup is set at the bottom end of the adsorption plate, and an adsorption frame is also provided on the mounting base. The adsorption frame and the adsorption plate are provided with mutually connected air pressure channels, and the adsorption frame is connected to the top of the lifting cylinder through a negative pressure pipe.

[0024] Beneficial effects of the present invention:

[0025] The present invention drives the support shaft to rotate by setting a rotating module, and the support shaft can synchronously drive the photovoltaic panel body to rotate when rotating; when the photovoltaic power generation device is in a strong wind environment, the rotating module can drive the photovoltaic panel body to rotate to a horizontal state through the support shaft, thereby reducing the cross-sectional area of ​​the photovoltaic panel body, thereby reducing its contact area with the wind, and thus achieving the effect of initially reducing wind force;

[0026] When the photovoltaic power generation device of the present invention is in a strong wind environment, the photovoltaic panel body can be driven down to a preset height by the lifting module to further reduce the force of the strong wind on the photovoltaic panel body and avoid the phenomenon that the photovoltaic panel body is damaged due to excessive wind force;

[0027] When the photovoltaic power generation device in the present invention is in an environment with strong wind, the impeller can drive the cam to rotate. During the rotation of the cam, the second piston can be pushed to slide in the cylinder body through the push plate and the rod body, so that the third cavity generates negative pressure. At this time, the second spring contracts to generate elastic force, and the oil delivery pipe extracts the hydraulic oil in the second cavity, and negative pressure is generated in the second cavity. The oil inlet pipe extracts the hydraulic oil in the first cavity. At the same time, the photovoltaic panel body descends. As the impeller drives the cam to continue to rotate, the second spring can drive the second piston to reset a certain distance to press part of the hydraulic oil in the third cavity back into the second cavity. However, since the inner diameter of the oil inlet pipe is larger than the inner diameter of the oil outlet pipe, the hydraulic oil drawn into the second cavity does not completely flow back to the first cavity. The cam continues to push the push plate to move and perform secondary oil absorption processing, and so on. When the strong wind disappears, the second spring can drive the second piston to completely reset, so that the hydraulic oil can all flow back to the first cavity and the second cavity, and the photovoltaic panel body is reset.

[0028] In the present invention, as the first piston descends, negative pressure is generated in the lifting cylinder above the first piston, and negative pressure can be synchronously generated at the suction cup through the negative pressure tube and the air pressure channel, thereby increasing the adsorption force of the suction cup when it contacts the ground, further improving the stability of the photovoltaic power generation device and avoiding the risk of tipping over. When the strong wind disappears, the suction cup also loses its adsorption force, thereby facilitating manual movement of the power generation device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Embodiment 1:

[0042] See also Figure 1 As shown, the present invention is a photovoltaic power generation device, including a photovoltaic panel body 1 and a mounting base 2, mounting frames 201 are arranged on both sides of the mounting base 2, and the mounting frames 201 on both sides are arranged in parallel and symmetrically, and the photovoltaic panel body 1 is arranged between the mounting frames 201 on both sides; specifically, the mounting frames 201 on both sides are fixed to the mounting base 2 by welding or bolting. When the photovoltaic power generation device is used, the mounting base 2 can be directly placed in the corresponding position, and there is no need to use bolts or pins to fix it to the floor, so as to avoid damage to the floor.

[0043] See also Figure 2-Figure 3, first support plates 105 are fixedly arranged at both ends of the back side of the photovoltaic panel body 1 close to the bottom, and a support shaft 106 is fixedly arranged between the two groups of first support plates 105. Rotation modules are also arranged on both sides of the photovoltaic panel body 1, and the rotation modules are used to drive the support shaft 106 to rotate; it should be noted that in order to improve the utilization rate of light energy of the photovoltaic panel body 1, the photovoltaic panel body 1 is usually arranged in an inclined state. In this embodiment, a rotation module is arranged to drive the support shaft 106 to rotate, and the support shaft 106 can synchronously drive the photovoltaic panel body 1 to rotate when rotating; specifically, when the photovoltaic power generation device is in a strong wind environment, the rotation module can drive the photovoltaic panel body 1 to rotate to a horizontal state through the support shaft 106, thereby reducing the cross-sectional area of ​​the photovoltaic panel body 1, so as to reduce its contact area with the wind, thereby achieving the effect of initially reducing wind force;

[0044] In this embodiment, please refer to Figure 7 A lifting module is also provided on the mounting base 2, and the lifting module is used to drive the photovoltaic panel body 1 to rise and fall; it can be explained that when the photovoltaic power generation device is in a strong wind environment, the lifting module can also drive the photovoltaic panel body 1 to descend to a preset height, so as to further reduce the force of the strong wind on the photovoltaic panel body 1, and avoid the phenomenon that the photovoltaic panel body 1 is damaged due to excessive wind.

[0045] Embodiment 2:

[0046] Based on Example 1, please refer to Figure 2-Figure 4 The rotating module includes gears 504 fixedly arranged at both ends of the support shaft 106, wherein racks 503 for meshing with the gears 504 are fixedly arranged on the sides close to the mounting frames 201 on both sides; specifically, when the lifting module drives the photovoltaic panel body 1 to lift, the photovoltaic panel body 1 synchronously drives the gear 504 to lift through the support shaft 106, and the gear 504 meshes with the rack 503 during the lifting process to drive the support shaft 106 to rotate. For example, the photovoltaic panel body 1 is initially in an inclined state, at which time the gear 504 meshes with the rack 503. When encountering strong winds, as the lifting module drives the photovoltaic panel body 1 to descend, the gear 504 meshes with the rack 503 to drive the photovoltaic panel body 1 to rotate from the inclined state to the horizontal state.

[0047] In order to prevent the photovoltaic panel body 1 from rotating freely after the gear 504 continues to descend and separates from the rack 503, in this embodiment, please refer to Figure 3-Figure 4 as well as Figure 6, a mounting plate 505 is further provided between the mounting frames 201 on both sides, a limiting frame 5 is fixedly arranged on both sides of the mounting plate 505, a limiting seat 501 is fixedly arranged on the side of the limiting frame 5 facing the gear 504, a screw 502 is spirally arranged in the limiting seat 501, a through groove is provided at one end of the screw 502 facing the gear 504, a telescopic rod 506 which is slidably inserted in the through groove is fixedly arranged at one end of the gear 504 away from the support shaft 106, wherein a plurality of groups of strip-shaped card slots 507 are circumferentially provided in the through groove, and a plurality of bar-shaped card slots 507 are fixedly arranged on the telescopic rod 506 The strip holder 508 is slidably engaged with the strip slot 507 in a one-to-one correspondence; specifically, when the driving gear 504 rotates, the gear 504 drives the screw 502 to rotate through the telescopic rod 506, the strip holder 508 and the strip slot 507. The screw 502 can move along its axial direction while rotating on the limit seat 501. Since the screw 502 and the limit seat 501 are spirally matched, even if the gear 504 is separated from the rack 503, the screw 502 will not rotate freely, and the stability is higher.

[0048] For further information, see Figure 4 An arc guide frame 101 is fixedly arranged on one end of the limit frame 5 away from the limit seat 501, and an arc guide groove 102 is provided on the arc guide frame 101, wherein second support plates 104 are fixedly arranged on both ends of the back side surface of the photovoltaic panel body 1 close to the top, and pins 103 are fixedly arranged on one end away from the second support plates 104 on both sides, and the other end of the pin 103 is slidably embedded in the arc guide groove 102; it can be explained that when the photovoltaic panel body 1 rotates around the support shaft 106, the pins 103 on both sides can slide synchronously along the arc guide groove 102 until the photovoltaic panel body 1 rotates to a horizontal state and stops.

[0049] See also Figure 2-Figure 3 as well as Figure 5The lifting module includes a lifting cylinder 3 fixedly arranged on both sides on the mounting base 2, a first piston 307 is slidably arranged in the lifting cylinder 3, the first piston 307 and the cylinder bottom are enclosed to form a first cavity 308 for storing hydraulic oil, a lifting rod 301 is fixedly arranged on the first piston 307, the other end of the lifting rod 301 is fixed to the lifting plate 306, a first spring 302 is arranged on the lifting rod 301, one end of the first spring 302 is fixed to the cylinder top, and the other end is fixed to the lifting plate 306, the mounting plate 505 is fixedly arranged on the lifting plate 306 through a connecting rod, wherein the first cavity 308 is connected to the oil delivery mechanism; it can be explained that, in the initial In the initial state, based on the setting of the first spring 302 and the hydraulic oil in the first cavity 308, the photovoltaic panel body 1 is in a normal light energy conversion state. When encountering strong wind weather, this embodiment uses the oil delivery mechanism to extract the hydraulic oil in the first cavity 308 to reduce the pressure in the first cavity 308, and then drives the lifting rod 301 to descend through the first piston 307. The lifting rod 301 drives the photovoltaic panel body 1 to descend through the lifting plate 306 and the mounting plate 505. Accordingly, when the strong wind weather passes, the oil delivery mechanism can re-input the hydraulic oil into the first cavity 308 to restore the photovoltaic panel body 1 to its initial state.

[0050] The oil conveying mechanism includes an oil storage cylinder 4 fixedly arranged on one side of the lifting cylinder 3, and a second cavity 409 is opened in the oil storage cylinder 4. One side of the bottom of the second cavity 409 is connected with the first cavity 308 through the oil inlet pipe 304, and a one-way valve limited to oil inlet is arranged between the oil inlet pipe 304 and the second cavity 409. The other side of the bottom of the second cavity 409 is connected with the first cavity 308 through the oil outlet pipe 303, and a one-way valve limited to oil discharge is arranged between the oil outlet pipe 303 and the second cavity 409. The top of the second cavity 409 is connected with a pumping mechanism for extracting the hydraulic oil in the second cavity 409. It can be explained that the pumping mechanism firstly extracts the hydraulic oil in the second cavity 409, and the hydraulic oil in the first cavity 308 can enter the second cavity 409 through the oil inlet pipe 304 under the action of negative pressure. When the pumping mechanism re-inputs the hydraulic oil into the second cavity 409, the hydraulic oil can be re-discharged into the first cavity 308 through the oil outlet pipe 303.

[0051] See also Figure 3 , Figure 5 as well as Figure 8The pumping mechanism includes a cylinder body 402 fixedly arranged on the mounting base 2, a second piston 411 is slidably arranged in the cylinder body 402, one side of the second piston 411 is surrounded by the side wall of the cylinder body 402 to form a third cavity 410, the third cavity 410 is connected with the top of the second cavity 409 through the oil delivery pipe 401, a rod body 403 fixed with the second piston 411 is slidably arranged on the cylinder wall on one side of the third cavity 410, the end of the rod body 403 is fixed with the push plate 405, and the rod body 403 A second spring 404 is provided on the top, one end of the second spring 404 is fixed to the cylinder body 402, and the other end is fixed to the push plate 405. A connecting frame 204 is also fixedly arranged between the mounting frames 201 on both sides, a support 408 is rotatably arranged on the connecting frame 204, an impeller 407 is fixedly arranged on the support 408, a cam 406 is fixedly arranged on the impeller 407, and the outer edge surface of the cam 406 is in sliding contact with the push plate 405, wherein the inner diameter of the oil inlet pipe 304 is greater than the inner diameter of the oil outlet pipe 303;

[0052] It can be explained that when the power generation device is in a windless or light wind environment, the impeller 407 cannot rotate, and thus the push plate 405 cannot push the second piston 411 to slide in the cylinder 402, so that the hydraulic oil cannot flow between the first cavity 308 and the second cavity 409, and thus the photovoltaic panel body 1 cannot be adjusted to rise and fall, and the photovoltaic panel body 1 is in a normal working state;

[0053] When the power generation device is in an environment with strong wind, the impeller 407 can drive the cam 406 to rotate. During the rotation process, the cam 406 can push the second piston 411 to slide in the cylinder 402 through the push plate 405 and the rod body 403, so that the third cavity 410 generates negative pressure. At this time, the second spring 404 contracts to generate elastic force, and the oil delivery pipe 401 draws out the hydraulic oil in the second cavity 409, and negative pressure is generated in the second cavity 409. The oil inlet pipe 304 draws out the hydraulic oil in the first cavity 308. At the same time, the photovoltaic panel body 1 descends (see Figure 7 ), as the impeller 407 drives the cam 406 to continue to rotate, the second spring 404 can drive the second piston 411 to reset a certain distance to press part of the hydraulic oil in the third cavity 410 back into the second cavity 409. However, since the inner diameter of the oil inlet pipe 304 is larger than the inner diameter of the oil outlet pipe 303, the hydraulic oil drawn into the second cavity 409 does not completely flow back to the first cavity 308. The cam 406 continues to push the push plate 405 to move and perform a secondary oil suction process, and so on. When the strong wind disappears, the second spring 404 can drive the second piston 411 to completely reset, so that the hydraulic oil can all flow back to the first cavity 308 and the second cavity 409, and the photovoltaic panel body 1 is reset.

[0054] It should be noted that if the cam 406 is still in the state of compressing the second spring 404 after the strong wind disappears, the impeller 407 can be rotated manually.

[0055] See also Figure 2-Figure 3 as well as Fig. 9 , a plurality of groups of adsorption plates 202 are evenly arranged on both sides of the mounting base 2, a suction cup 203 is arranged at the bottom end of the adsorption plate 202, and an adsorption frame 205 is also arranged on the mounting base 2, and an air pressure channel interconnected with each other is opened in the adsorption frame 205 and the adsorption plate 202, and the adsorption frame 205 is connected with the top of the lifting cylinder 3 through the negative pressure pipe 305; it can be explained that as the first piston 307 descends, a negative pressure is generated in the lifting cylinder 3 above the first piston 307, and a negative pressure can be synchronously generated at the suction cup 203 through the negative pressure pipe 305 and the air pressure channel, so that the adsorption force of the suction cup 203 when it contacts the ground can be improved, and the stability of the photovoltaic power generation device can be further improved to avoid the risk of tipping over. Correspondingly, when the strong wind disappears, the suction cup 203 also loses its adsorption force, which makes it easier to manually move the power generation device.

[0056] The working principle of the present invention is: please refer to Figure 2-Figure 5 as well as Figure 8 The present invention is provided with an impeller 407. When the power generation device is in an environment with strong wind, the impeller 407 can drive the cam 406 to rotate. During the rotation process, the cam 406 can push the second piston 411 to slide in the cylinder 402 through the push plate 405 and the rod body 403, so that the third cavity 410 generates negative pressure. At this time, the second spring 404 contracts to generate elastic force, and the oil delivery pipe 401 extracts the hydraulic oil in the second cavity 409, and negative pressure is generated in the second cavity 409. The oil inlet pipe 304 extracts the hydraulic oil in the first cavity 308. At the same time, the photovoltaic panel body 1 descends (see Figure 7 ), as the photovoltaic panel body 1 descends, the gear 504 meshes with the rack 503 to drive the photovoltaic panel body 1 to rotate from an inclined state to a horizontal state, so as to reduce the contact area between the photovoltaic panel body 1 and the wind and improve its wind resistance. As the impeller 407 drives the cam 406 to continue to rotate, the second spring 404 can drive the second piston 411 to reset a certain distance to press part of the hydraulic oil in the third cavity 410 back into the second cavity 409. However, since the inner diameter of the oil inlet pipe 304 is larger than the inner diameter of the oil outlet pipe 303, the hydraulic oil drawn into the second cavity 409 does not completely flow back to the first cavity 308. The cam 406 continues to push the push plate 405 to move and perform a secondary oil absorption process, and so on. When the strong wind disappears, the second spring 404 can drive the second piston 411 to completely reset, so that the hydraulic oil can all flow back to the first cavity 308 and the second cavity 409, and the photovoltaic panel body 1 is reset.
