Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and specifically provides a photovoltaic power generation device with a protection mechanism. Background Art

[0002] A photovoltaic power generation device with a protection mechanism is usually used for photovoltaic power generation in areas with relatively harsh natural environmental factors, aiming to be able to generate electricity using light energy in some areas with poor environments.

[0003] The patent with the patent publication number CN218633836U relates to the technical field of photovoltaic power generation and discloses a photovoltaic power generation panel device with a protection function, including a photovoltaic power generation mechanism. The photovoltaic power generation mechanism includes a photovoltaic power generation panel body. A left bracket is movably connected to the left side of the inner cavity of the photovoltaic power generation panel body, and a left support plate is fixedly connected to the bottom of the left bracket. For this photovoltaic power generation panel device with a protection function, by pulling the pulling ring to move the second protection plate to the left, the movement of the second protection plate drives the connecting plate to move, and the movement of the connecting plate causes the reset spring to stretch and deform. Then, the second protection plate is snapped into the internal card slot. At this time, the second protection plate extends out from the first protection plate, achieving the advantage of the protection function and solving the problem that the existing photovoltaic power generation panels are used exposed, lacking a protection structure, and being easily damaged in extreme weather. For example, when hail directly falls on its surface, the photovoltaic power generation panel will break.

[0004] In the above patent, the protection of the photovoltaic power generation panel in many cases is achieved by adding a protection plate on the top surface of the photovoltaic power generation panel. However, in the case of extremely strong wind weather, if the whole device cannot be stabilized in time, it may cause the device to tip over and be damaged. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a photovoltaic power generation device with a protection mechanism, solving the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a photovoltaic power generation device with a protective mechanism, comprising a base, a support column fixedly installed on the top of the base, a thick connecting rod slidably installed on the top of the support column, a main photovoltaic panel rotatably installed on the top of the thick connecting rod, a component table fixedly installed on the circumferential surface of the support column, an anemometer rotatably installed on the top of the component table, a telescopic top rod fixedly installed on the circumferential surface of the bottom of the anemometer, an inner hydraulic cylinder is arranged inside the support column, a deflection block is rotatably installed on the circumferential surface of the support column, an inner partition is fixedly installed on the inner wall of the inner hydraulic cylinder, an open hole baffle is rotatably installed on the top of the inner partition, fine holes are opened on the surface of the open hole baffle, and the thick connecting rod is fixedly installed on the circumferential surface of the support column. A hydraulic rod is fixedly installed at the bottom of the rod, a side push rod is fixedly installed on the circumferential surface of the support column, a vertical limit groove is opened on the circumferential surface of the thick connecting rod, and a telescopic limit rod is fixedly installed at the bottom of the main photovoltaic panel. The deflection block is deflected by the anemometer and the telescopic push rod, so that the hydraulic oil flows from the upper part of the inner hydraulic cylinder to the lower part through the fine hole, so that when the wind speed reaches a certain level, the main photovoltaic panel is released from the limit and lowered in height to lower the overall center of gravity of the device, thereby minimizing the impact of wind on the device. At the same time, the limit between the main photovoltaic panel and the thick connecting rod is released by the side push rod and the telescopic limit rod, so that the main photovoltaic panel is restored to a horizontal position under the action of the volute spring, further reducing the impact of wind on the overall device.

[0007] According to the above technical scheme, the deflection block is located on the movement trajectory of the telescopic push rod, the side push rod is located on the movement trajectory of the telescopic limit rod, the bottom of the deflection block contacts the top of the open hole baffle, a hydraulic oil tank is fixedly installed on the top of the component table, a hydraulic valve is fixedly installed on the top of the hydraulic oil tank, a valve switch is fixedly installed on the control end of the hydraulic valve, the hydraulic valve and the inner hydraulic cylinder are connected through a hydraulic oil pipe, the hydraulic valve is connected to the hydraulic oil tank, a volute spring 1 is arranged between the main photovoltaic panel and the thick connecting rod, the valve switch is turned to open the hydraulic valve, and the hydraulic oil in the upper part of the inner hydraulic cylinder flows into the hydraulic oil tank through the hydraulic oil pipe and the hydraulic valve, thereby realizing the height adjustment of the main photovoltaic panel under normal circumstances.

[0008] According to the above technical scheme, an auxiliary fixing device is arranged on the top of the component platform, and the auxiliary fixing device includes an L-shaped hydraulic cylinder, a hydraulic push rod, a rotating pin and a limit pin groove. The L-shaped hydraulic cylinder is fixedly installed on the circumferential surface of the support column, the hydraulic push rod is slidably installed on the inner wall of the L-shaped hydraulic cylinder, the rotating pin is rotatably installed on the top of the hydraulic push rod, and the limit pin groove is fixedly installed on the bottom of the main photovoltaic panel. The hydraulic push rod is driven to move upward by squeezing the hydraulic oil during the descent of the hydraulic rod, and the hydraulic push rod contacts with the bottom of the main photovoltaic panel during the upward movement. Therefore, after the main photovoltaic panel is lowered, the hydraulic push rod rises to contact and support it, thereby further improving the overall stability of the device in windy weather.

[0009] According to the above technical solution, the auxiliary fixing device further includes a sliding limit rod, a rotating clamping rod and a triangular top block. The sliding limit rod is slidably installed at the bottom of the main photovoltaic panel. The rotating clamping rod is rotatably installed at the bottom of the main photovoltaic panel. A stable clamping groove is formed at the bottom of the rotating clamping rod, and a rotating limit groove is formed at the front of the rotating clamping rod. An auxiliary clamping groove is formed at the rear of the component table. A triangular top block is slidably installed on the inner wall of the auxiliary clamping groove. The rotating pin releases the limit of the rotating clamping rod through the sliding limit rod, so that the stable clamping groove of the rotating clamping rod contacts the component table to form a limit, further improving the stability of the device.

[0010] According to the above technical solution, the main photovoltaic panel is located on the movement track of the rotating pin, the limit pin groove is located on the movement track of the rotating pin, the triangular top block is located on the movement track of the rotating clamping rod, the sliding limit rod is located on the movement track of the rotating pin. A first return spring is arranged between the triangular top block and the component table. The sliding limit rod contacts the inner wall of the rotating limit groove. The component table is located on the movement track of the stable clamping groove. A second scroll spring is arranged between the rotating pin and the hydraulic ejector rod. The resilient force of the second scroll spring can ensure that the rotating pin is in a non-horizontal state before contacting the main photovoltaic panel, so that its subsequent rotation can drive the sliding limit rod to slide through the contact.

[0011] According to the above technical solution, two automatic rotating shafts are rotatably installed on the side surface of the main photovoltaic panel. Sub-photovoltaic panels are fixedly installed on the circumferential surfaces of the two automatic rotating shafts. A universal ejector rod is rotatably installed on the top of the component table. A strip-shaped pin is slidably installed at the bottom of the main photovoltaic panel. The top of the universal ejector rod is rotatably connected to the bottom of the strip-shaped pin. A hinge is rotatably installed at the bottom of the main photovoltaic panel. One end of the hinge away from the main photovoltaic panel is rotatably connected to the bottom of the sub-photovoltaic panel. A horizontal pin groove is formed on the side surface of the hinge. The sub-photovoltaic panel can improve the power generation efficiency of the device under normal circumstances. At the same time, when extreme weather occurs, it can be folded and stored, reducing the surface area of the total photovoltaic panel and its contact area with the wind, that is, improving the overall working efficiency of the device and the stability during work.

[0012] According to the above technical solution, a reciprocating hook is slidably installed on the right side of the hinge, and a side hook is slidably installed on the top of the sub-photovoltaic panel. The limit formed between the reciprocating hook and the side hook can prevent the sub-photovoltaic panel from rotating after being folded and stored, thus avoiding the sub-photovoltaic panel being rotated and opened again by the wind after folding.

[0013] According to the above technical solution, a scroll spring III is arranged inside the automatic rotating shaft. The strip-shaped bolt is in contact with the inner wall of the horizontal pin slot. A return spring II is arranged between the reciprocating hook and the hinge. The reciprocating hook is located on the movement track of the secondary photovoltaic panel, and the side hook is located on the movement track of the reciprocating hook. The scroll spring III of the automatic rotating shaft enables the secondary photovoltaic panel to rotate and fold on its own under the elastic force of the scroll spring III after the limit between the strip-shaped bolt and the horizontal pin slot is released.

[0014] The present invention provides a photovoltaic power generation device with a protection mechanism. It has the following beneficial effects: 1. In this invention, the deflection stopper is deflected by the anemometer and the telescopic ejector rod, so that the hydraulic oil flows from the upper part to the lower part of the inner hydraulic cylinder through the fine holes, realizing that when the wind speed reaches a certain level, the main photovoltaic panel is released from the limit and its height is reduced to lower the overall center of gravity of the device, minimizing the impact of wind on the device as much as possible. At the same time, the limit between the main photovoltaic panel and the thick connecting rod is released by the side ejector rod and the telescopic limiting rod, and the main photovoltaic panel returns to the horizontal position under the action of the scroll spring, further reducing the impact of wind on the overall device.

[0015] 2. In this invention, when the hydraulic rod descends, it squeezes the hydraulic oil to drive the hydraulic ejector rod to move upward. When the hydraulic ejector rod moves upward and contacts the bottom of the main photovoltaic panel, it realizes that after the main photovoltaic panel descends, the hydraulic ejector rod rises to contact and support it, further improving the overall stability of the device in strong wind weather. At the same time, the rotating pin releases the limit of the rotating rod through the sliding limiting rod, and the stable clamping groove of the rotating rod contacts the component platform to form a limit, further enhancing the stability of the device.

[0016] 3. In this invention, after the main photovoltaic panel descends, the limit between the main photovoltaic panel and the secondary photovoltaic panel is released by the universal ejector rod and the strip-shaped bolt, enabling the secondary photovoltaic panel to be folded and stored, thereby reducing the overall surface area of the device and the surface area of the photovoltaic panel in contact with the wind. At the same time, a limit is formed between the reciprocating hook and the side hook to enable the photovoltaic panel to form a self-lock after folding, preventing the secondary photovoltaic panel from being reopened due to the influence of extreme strong wind weather, thus further enhancing the overall safety of the device.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-7, a photovoltaic power generation device with a protection mechanism, including a base 1. A support column 2 is fixedly installed at the top of the base 1.

A telescopic ejector rod 602 is fixedly installed on the circumferential surface of the bottom of the anemometer 601. An inner hydraulic cylinder is arranged inside the support column 2. A deflection stopper 603 is rotatably installed on the circumferential surface of the support column 2. An inner partition is fixedly installed on the inner wall of the inner hydraulic cylinder. An opening baffle 604 is rotatably installed at the top of the inner partition. Fine holes are formed on the surface of the opening baffle 604. A hydraulic rod 605 is fixedly installed at the bottom of the thick connecting rod. A side ejector rod 606 is fixedly installed on the circumferential surface of the support column 2. A vertical limiting groove is formed on the circumferential surface of the thick connecting rod. A telescopic limiting rod 607 is fixedly installed at the bottom of the main photovoltaic panel 3. The deflection stopper 603 is deflected by the anemometer 601 and the telescopic ejector rod 602, so that the hydraulic oil flows from the upper part to the lower part of the inner hydraulic cylinder through the fine holes, realizing that when the wind speed reaches a certain level, the main photovoltaic panel 3 releases the limit and reduces the height to lower the overall center of gravity of the device, minimizing the impact of the wind on the device as much as possible. At the same time, the limit between the main photovoltaic panel 3 and the thick connecting rod is released by the side ejector rod 606 and the telescopic limiting rod 607, and the main photovoltaic panel 3 returns to the horizontal position under the action of the volute spring, further reducing the impact of the wind on the overall device.

[0021] The deflection stopper 603 is located on the movement track of the telescopic ejector rod 602. The side ejector rod 606 is located on the movement track of the telescopic limiting rod 607. The bottom of the deflection stopper 603 contacts the top of the opening baffle 604. A hydraulic oil tank 7 is fixedly installed at the top of the component platform 5. A hydraulic valve is fixedly installed at the top of the hydraulic oil tank 7. A valve switch 8 is fixedly installed at the control end of the hydraulic valve. The hydraulic valve is connected to the inner hydraulic cylinder through a hydraulic oil pipe. The hydraulic valve is connected to the hydraulic oil tank 7. A volute spring one is arranged between the main photovoltaic panel 3 and the thick connecting rod. Rotate the valve switch 8 to open the hydraulic valve, and the hydraulic oil in the upper part of the inner hydraulic cylinder flows into the hydraulic oil tank 7 through the hydraulic oil pipe and the hydraulic valve, realizing the height adjustment of the main photovoltaic panel 3 under normal conditions of the device.

[0022] An auxiliary fixing device is provided on the top of the component table 5. The auxiliary fixing device includes an L-shaped hydraulic cylinder 901, a hydraulic ejector rod 902, a rotating pin 903, and a limit pin slot 904. The L-shaped hydraulic cylinder 901 is fixedly installed on the circumferential surface of the support column 2. The hydraulic ejector rod 902 is slidably installed on the inner wall of the L-shaped hydraulic cylinder 901. The rotating pin 903 is rotatably installed on the top of the hydraulic ejector rod 902. The limit pin slot 904 is fixedly installed on the bottom of the main photovoltaic panel 3. During the downward movement of the hydraulic rod 605, the hydraulic oil is squeezed to drive the hydraulic ejector rod 902 to move upward. When the hydraulic ejector rod 902 moves upward and contacts the bottom of the main photovoltaic panel 3, it realizes that after the main photovoltaic panel 3 descends, the hydraulic ejector rod 902 rises to contact and support it, further improving the overall stability of the device in strong wind weather.

[0023] The auxiliary fixing device further includes a sliding limit rod 905, a rotating clamping rod 906, and a triangular top block 907. The sliding limit rod 905 is slidably installed on the bottom of the main photovoltaic panel 3. The rotating clamping rod 906 is rotatably installed on the bottom of the main photovoltaic panel 3. A stable clamping groove is provided at the bottom of the rotating clamping rod 906, and a rotating limit groove is provided at the front of the rotating clamping rod 906. An auxiliary clamping groove is provided at the rear of the component table 5. The triangular top block 907 is slidably installed on the inner wall of the auxiliary clamping groove. The rotating pin 903 releases the limit of the rotating clamping rod 906 through the sliding limit rod 905, so that the stable clamping groove of the rotating clamping rod 906 contacts the component table 5 to form a limit, further improving the stability of the device.

[0024] The main photovoltaic panel 3 is located on the movement track of the rotating pin 903. The limit pin slot 904 is located on the movement track of the rotating pin 903. The triangular top block 907 is located on the movement track of the rotating clamping rod 906. The sliding limit rod 905 is located on the movement track of the rotating pin 903. A first reset spring is provided between the triangular top block 907 and the component table 5. The sliding limit rod 905 contacts the inner wall of the rotating limit groove. The component table 5 is located on the movement track of the stable clamping groove. A second scroll spring is provided between the rotating pin 903 and the hydraulic ejector rod 902. The elastic force of the second scroll spring can ensure that the rotating pin 903 is in a non-horizontal state before contacting the main photovoltaic panel 3, so that its subsequent rotation can drive the sliding limit rod 905 to slide through the contact.

[0025] On the side of the main photovoltaic panel 3, two automatic rotating shafts 1001 are rotatably installed. On the circumferential surfaces of the two automatic rotating shafts 1001, auxiliary photovoltaic panels 4 are fixedly installed. On the top of the component table 5, a universal ejector rod 1002 is rotatably installed. At the bottom of the main photovoltaic panel 3, a strip-shaped bolt 1003 is slidably installed. The top of the universal ejector rod 1002 is rotatably connected to the bottom of the strip-shaped bolt 1003. At the bottom of the main photovoltaic panel 3, a hinge 1004 is rotatably installed. One end of the hinge 1004 away from the main photovoltaic panel 3 is rotatably connected to the bottom of the auxiliary photovoltaic panel 4. A horizontal pin slot 1005 is formed on the side of the hinge 1004. The auxiliary photovoltaic panel 4 can improve the power generation efficiency of the device under normal circumstances. At the same time, when extreme weather occurs, it can be folded and stored, reducing the surface area of the total photovoltaic panel and its contact area with the wind, that is, while improving the overall working efficiency of the device, the stability during operation is also improved.

[0026] A reciprocating hook 1006 is slidably installed on the right side of the hinge 1004. A side hook 1007 is slidably installed on the top of the auxiliary photovoltaic panel 4. The limit formed between the reciprocating hook 1006 and the side hook 1007 can prevent the auxiliary photovoltaic panel 4 from rotating again after being folded and stored, thus avoiding the auxiliary photovoltaic panel 4 being rotated and opened again by the wind after folding.

[0027] A scroll spring three is arranged inside the automatic rotating shaft 1001. The strip-shaped bolt 1003 is in contact with the inner wall of the horizontal pin slot 1005. A return spring two is arranged between the reciprocating hook 1006 and the hinge 1004. The reciprocating hook 1006 is located on the movement track of the auxiliary photovoltaic panel 4, and the side hook 1007 is located on the movement track of the reciprocating hook 1006. The scroll spring three of the automatic rotating shaft 1001 enables the auxiliary photovoltaic panel 4 to rotate and fold automatically under the elastic force of the scroll spring three after the limit between the strip-shaped bolt 1003 and the horizontal pin slot 1005 is released.

[0028] During operation: When extreme high wind weather occurs at the location where the device is located, that is, when the wind speed reaches a certain level, the wind force drives the anemometer 601 to rotate, thus driving the telescopic ejector rod 602 to rotate together. As the wind force gradually increases, the rotation speed of the anemometer 601 also gradually increases. When the rotation speed of the anemometer 601 increases to a certain level, the telescopic ejector rod 602 extends outwards under the action of centrifugal force. Then, during the rotation process, the telescopic ejector rod 602 contacts the deflection block 603 and causes the deflection block 603 to deflect, so that the bottom of the deflection block 603 is separated from the fine hole. After the separation, the main photovoltaic panel 3, the thick connecting rod, and the hydraulic rod 605 slide downward under the action of gravity. Thus, when the wind speed reaches a certain level, the main photovoltaic panel 3 slides downward, reducing the overall center of gravity of the device and enhancing the overall stability of the device. At the same time, during the downward movement of the main photovoltaic panel 3, the telescopic limit rod 607 is driven to slide downward together and contacts the side ejector rod 606. After the contact, the telescopic limit rod 607 contracts, releasing the limit between the main photovoltaic panel 3 and the thick connecting rod. Then, under the elastic force of the first volute spring, the main photovoltaic panel 3 returns to the horizontal position, reducing the angle between the photovoltaic panel and the wind, and further enhancing the overall stability of the device.

[0029] During the downward sliding process of the hydraulic rod 605, it drives the hydraulic ejector rod 902 to slide upward by squeezing the hydraulic oil inside the inner hydraulic cylinder. During the upward sliding process of the hydraulic ejector rod 902, its top contacts and supports the bottom of the main photovoltaic panel 3, thus enhancing the stability of the main photovoltaic panel 3 after it descends. At the same time, when the hydraulic ejector rod 902 slides upward, it drives the rotating pin 903 to slide upward together. After the rotating pin 903 slides a certain distance, it contacts the bottom of the main photovoltaic panel 3 and rotates while sliding. When the rotating pin 903 rotates, it contacts the limit pin slot 904 and forms a limit. At the same time, during the rotation process of the rotating pin 903, it contacts the sliding limit rod 905 and drives it to slide. When the sliding limit rod 905 slides, it is separated from the rotation limit slot of the rotating latch 906, releasing the limiting effect of the rotating latch 906. Then, under the action of gravity, the rotating latch 906 rotates downward and contacts the triangular ejector block 907, driving the triangular ejector block 907 to retract into the component platform 5. After the triangular ejector block 907 continues to rotate and is separated from the triangular ejector block 907, under the elastic force of the first return spring, the triangular ejector block 907 extends out of the component platform 5 again, realizing the limitation of the rotating latch 906. After the rotating latch 906 rotates downward, the stable card slot contacts the component platform 5 and forms a limit, further enhancing the overall stability of the device after the main photovoltaic panel 3 descends.

[0030] Since the top of the universal ejector rod 1002 is rotatably connected to the bottom of the bar-shaped pin 1003 and the bar-shaped pin 1003 is slidably installed at the bottom of the main photovoltaic panel 3, when the main photovoltaic panel 3 slides downward, it drives the universal ejector rod 1002 to rotate, thereby driving the bar-shaped pin 1003 to slide. After the bar-shaped pin 1003 slides, it disengages from the horizontal pin slot 1005. After the disengagement, the limit between the bar-shaped pin 1003 and the horizontal pin slot 1005 is released, enabling the secondary photovoltaic panel 4 to rotate under the resilient force of the torsion spring three of the automatic rotating shaft 1001. Thus, when the main photovoltaic panel 3 descends, the secondary photovoltaic panel 4 rotates and folds, reducing the overall surface area of the photovoltaic panels and the surface area in contact with the wind, thereby reducing the impact of the wind on the overall device. While the secondary photovoltaic panel 4 rotates, it drives the side hook 1007 to rotate together. When the side hook 1007 rotates to a certain position, it contacts the reciprocating hook 1006. At the same time, the rotation of the secondary photovoltaic panel 4 contacts the reciprocating hook 1006 and drives it to slide. During the sliding process of the reciprocating hook 1006, it forms a limit with the side hook 1007, thus preventing the secondary photovoltaic panel 4 from being blown open again due to strong wind after the photovoltaic panels are folded, further ensuring the protection stability of the device in a truly extreme environment.
