Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, specifically to a photovoltaic power generation device with a protective mechanism. Background Technology

[0002] Photovoltaic power generation devices with protective mechanisms are typically used in areas with harsh natural environmental factors, with the aim of enabling the generation of electricity using solar energy even in some areas with harsh environments.

[0003] Patent publication number CN218633836U relates to the field of photovoltaic power generation technology and discloses a photovoltaic power generation panel device with protective function. The device includes a photovoltaic power generation mechanism, which comprises a photovoltaic power generation panel body. A left support 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 support. This protective photovoltaic power generation panel device works by pulling a second protective plate to the left via a pull ring. The movement of the second protective plate causes a connecting plate to move, which in turn stretches and deforms a return spring, causing the second protective plate to be inserted into a slot. At this point, the second protective plate extends out from within the first protective plate, achieving the advantage of protective function. This solves the problem that existing photovoltaic power generation panels are exposed to the elements and lack protective structures, making them susceptible to damage in extreme weather conditions, such as hail directly hitting their surface and causing them to crack.

[0004] In the aforementioned patent, a protective plate is added to the top surface of the photovoltaic panel to provide protection for the photovoltaic panel in most situations. However, in extreme windy weather, if the entire device is not stabilized in time, it may tip over and be damaged. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a photovoltaic power generation device with a protective mechanism, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic power generation device with a protective mechanism, comprising a base, a support column fixedly mounted on the top of the base, a thick connecting rod slidably mounted on the top of the support column, a main photovoltaic panel rotatably mounted on the top of the thick connecting rod, a component platform fixedly mounted on the circumferential surface of the support column, an anemometer rotatably mounted on the top of the component platform, a telescopic top rod fixedly mounted on the bottom circumferential surface of the anemometer, an internal hydraulic cylinder provided inside the support column, a deflection stop rotatably mounted on the circumferential surface of the support column, an internal partition fixedly mounted on the inner wall of the internal hydraulic cylinder, an open baffle rotatably mounted on the top of the internal partition, and fine holes formed on the surface of the open baffle. A hydraulic rod is fixedly installed at the bottom of the pole, a side top rod is fixedly installed on the circumferential surface of the support column, a vertical limiting groove is opened on the circumferential surface of the thick connecting rod, and a telescopic limiting rod is fixedly installed at the bottom of the main photovoltaic panel. The deflection block is deflected by the anemometer and the telescopic top rod, so that hydraulic oil flows from the upper part to the lower part of the inner hydraulic cylinder through the fine hole. This allows the main photovoltaic panel to release the limit and lower its height when the wind speed reaches a certain level, thereby lowering the overall center of gravity of the device and 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 top rod and the telescopic limiting rod, so that the main photovoltaic panel returns to the horizontal position under the action of the spiral spring, further reducing the impact of wind on the overall device.

[0007] According to the above technical solution, the deflection block is located on the movement trajectory of the telescopic top rod, the side top rod is located on the movement trajectory of the telescopic limit rod, the bottom of the deflection block contacts the top of the opening baffle, a hydraulic oil tank is fixedly installed on the top of the component platform, 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 is connected to the inner hydraulic cylinder through a hydraulic oil pipe, the hydraulic valve is connected to the hydraulic oil tank, and a spiral spring is provided between the main photovoltaic panel and the thick connecting rod. By rotating the valve switch to open the hydraulic valve, 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, thus realizing the height adjustment of the main photovoltaic panel under normal conditions.

[0008] According to the above technical solution, an auxiliary fixing device is provided on the top of the component platform. The auxiliary fixing device includes an L-shaped hydraulic cylinder, a hydraulic push rod, a rotating pin, and a limiting 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. The limiting pin groove is fixedly installed on the bottom of the main photovoltaic panel. During the descent of the hydraulic rod, the hydraulic oil is squeezed to drive the hydraulic push rod to move upward. During the upward movement of the hydraulic push rod, it contacts the bottom of the main photovoltaic panel, thus realizing that after the main photovoltaic panel is lowered, the hydraulic push rod rises to contact and support it, 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 locking rod, and a triangular top block. The sliding limit rod is slidably installed at the bottom of the main photovoltaic panel, and the rotating locking rod is rotatably installed at the bottom of the main photovoltaic panel. A stabilizing groove is provided at the bottom of the rotating locking rod, and a rotating limit groove is provided at the front of the rotating locking rod. An auxiliary groove is provided at the rear of the component platform, and a triangular top block is slidably installed on the inner wall of the auxiliary groove. The rotating pin releases the limiting position of the rotating locking rod through the sliding limit rod, so that the stabilizing groove of the rotating locking rod contacts the component platform to form a limit, thereby further improving the stability of the device.

[0010] According to the above technical solution, the main photovoltaic panel is located on the movement trajectory of the rotating pin, the limiting pin groove is located on the movement trajectory of the rotating pin, the triangular apex is located on the movement trajectory of the rotating clamp, the sliding limiting rod is located on the movement trajectory of the rotating pin, a return spring is provided between the triangular apex and the component platform, the sliding limiting rod is in contact with the inner wall of the rotating limiting groove, the component platform is located on the movement trajectory of the stabilizing clamp, and a spiral spring is provided between the rotating pin and the hydraulic jack. The rebound force of the spiral spring ensures that the rotating pin is not horizontal before contacting the main photovoltaic panel, so that its subsequent rotation can drive the sliding limiting rod to slide through contact.

[0011] According to the above technical solution, two automatic rotating shafts are rotatably installed on the side of the main photovoltaic panel, and auxiliary photovoltaic panels are fixedly installed on the circumferential surfaces of the two automatic rotating shafts. A universal top rod is rotatably installed on the top of the component platform, and a strip pin is slidably installed on the bottom of the main photovoltaic panel. The top of the universal top rod is rotatably connected to the bottom of the strip pin. A hinge is rotatably installed on the bottom of the main photovoltaic panel, and the end of the hinge away from the main photovoltaic panel is rotatably connected to the bottom of the auxiliary photovoltaic panel. A horizontal pin groove is opened on the side of the hinge. The auxiliary photovoltaic panel can improve the power generation efficiency of the device under normal conditions. At the same time, it can be folded and stored in extreme weather conditions to reduce the surface area of ​​the total photovoltaic panel and its contact area with the wind. This achieves both improved overall working efficiency and improved stability during operation.

[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 limiting action formed between the reciprocating hook and the side hook can prevent the sub-photovoltaic panel from being rotated again after being folded and stored, thereby preventing the sub-photovoltaic panel from being rotated and opened again due to wind force after being folded.

[0013] According to the above technical solution, the automatic rotating shaft is equipped with a spiral spring three inside, the strip pin contacts the inner wall of the horizontal pin groove, the reciprocating hook is equipped with a reset spring two between the reciprocating hook and the hinge, the reciprocating hook is located on the movement trajectory of the sub-photovoltaic panel, the side hook is located on the movement trajectory of the reciprocating hook, and the spiral spring three of the automatic rotating shaft enables the sub-photovoltaic panel to rotate and fold on its own under the rebound force of the spiral spring three after the limit between the strip pin and the horizontal pin groove is released.

[0014] This invention provides a photovoltaic power generation device with a protective mechanism. It has the following beneficial effects:

[0015] This invention uses an anemometer and a telescopic rod to deflect the deflection block, causing hydraulic oil to flow from the upper part to the lower part of the inner hydraulic cylinder through a fine hole. This allows the main photovoltaic panel to release its limit and lower its height when the wind speed reaches a certain level, thereby lowering the overall center of gravity of the device and minimizing the impact of wind on the device. At the same time, the side rod and telescopic limit rod release the limit between the main photovoltaic panel and the thick connecting rod, allowing the main photovoltaic panel to return to a horizontal position under the action of the spiral spring, further reducing the impact of wind on the overall device.

[0016] This invention utilizes the hydraulic rod's downward movement to compress hydraulic oil, causing the hydraulic jack to move upward. During this upward movement, the hydraulic jack contacts the bottom of the main photovoltaic panel, thus enabling the hydraulic jack to rise and support the panel after its descent. This further improves the overall stability of the device in windy conditions. Simultaneously, the rotating pin releases the limiting position of the rotating lever via a sliding limit rod, allowing the stable groove of the rotating lever to contact the component platform, thereby creating a limit and further enhancing the device's stability.

[0017] This invention allows the main photovoltaic panel to be lowered, and the limiting mechanism between the main photovoltaic panel and the secondary photovoltaic panel to be released through the universal top rod and the strip pin, so that the secondary photovoltaic panel can be folded and stored. This reduces the overall surface area of ​​the device and the surface area of ​​the photovoltaic panel in contact with the wind. At the same time, the reciprocating hook and the side hook form a limiting mechanism so that the photovoltaic panel can be self-locked after being folded, preventing the secondary photovoltaic panel from being reopened due to extreme wind conditions, thereby further improving the overall safety of the device.

[0026] 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.

[0027] Please see Figures 1-7A photovoltaic power generation device with a protective mechanism includes a base 1, a support column 2 fixedly mounted on the top of the base 1, a thick connecting rod slidably mounted on the top of the support column 2, a main photovoltaic panel 3 rotatably mounted on the top of the thick connecting rod, a component platform 5 fixedly mounted on the circumferential surface of the support column 2, an anemometer 601 rotatably mounted on the top of the component platform 5, a telescopic top rod 602 fixedly mounted on the bottom circumferential surface of the anemometer 601, an internal hydraulic cylinder provided inside the support column 2, a deflection stop 603 rotatably mounted on the circumferential surface of the support column 2, an internal partition plate fixedly mounted on the inner wall of the internal hydraulic cylinder, an opening baffle 604 rotatably mounted on the top of the internal partition plate, the opening baffle 604 having fine holes on its surface, a hydraulic rod 605 fixedly mounted on the bottom of the thick connecting rod, and the support column 2's circumferential surface... A side top rod 606 is fixedly installed on the circumference of the main photovoltaic panel 3. A vertical limiting groove is opened on the circumference of the thick connecting rod. A telescopic limiting rod 607 is fixedly installed at the bottom of the main photovoltaic panel 3. The deflection block 603 is deflected by the anemometer 601 and the telescopic top rod 602, so that the hydraulic oil flows from the upper part of the inner hydraulic cylinder to the lower part through the fine hole. This realizes that when the wind speed reaches a certain level, the main photovoltaic panel 3 is released from the limit and lowers its height to lower the overall center of gravity of the device, minimizing the impact of wind on the device. At the same time, the side top rod 606 and the telescopic limiting rod 607 release the limit between the main photovoltaic panel 3 and the thick connecting rod, so that the main photovoltaic panel 3 returns to the horizontal position under the action of the spiral spring, further reducing the impact of wind on the overall device.

[0028] The deflection block 603 is located on the movement trajectory of the telescopic top rod 602, and the side top rod 606 is located on the movement trajectory of the telescopic limit rod 607. The bottom of the deflection block 603 contacts the top of the perforated baffle 604. A hydraulic oil tank 7 is fixedly installed on the top of the component platform 5. A hydraulic valve is fixedly installed on the top of the hydraulic oil tank 7. A valve switch 8 is fixedly installed on 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 spiral spring is set between the main photovoltaic panel 3 and the thick connecting rod. Rotating the valve switch 8 opens the hydraulic valve. 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, thus realizing the height adjustment of the main photovoltaic panel 3 under normal conditions.

[0029] An auxiliary fixing device is provided on the top of component platform 5. The auxiliary fixing device includes an L-shaped hydraulic cylinder 901, a hydraulic push rod 902, a rotating pin 903, and a limiting pin groove 904. The L-shaped hydraulic cylinder 901 is fixedly installed on the circumferential surface of the support column 2. The hydraulic push 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 push rod 902. The limiting pin groove 904 is fixedly installed on the bottom of the main photovoltaic panel 3. When the hydraulic rod 605 descends, it squeezes the hydraulic oil to drive the hydraulic push rod 902 to move upward. During the upward movement of the hydraulic push rod 902, it contacts the bottom of the main photovoltaic panel 3. This realizes that after the main photovoltaic panel 3 descends, the hydraulic push rod 902 rises up to contact and support it, which further improves the overall stability of the device in windy weather.

[0030] The auxiliary fixing device also includes a sliding limit rod 905, a rotating locking rod 906, and a triangular apex block 907. The sliding limit rod 905 is slidably installed at the bottom of the main photovoltaic panel 3, and the rotating locking rod 906 is rotatably installed at the bottom of the main photovoltaic panel 3. A stabilizing groove is provided at the bottom of the rotating locking rod 906, and a rotating limiting groove is provided at the front of the rotating locking rod 906. An auxiliary groove is provided at the rear of the component platform 5. The triangular apex block 907 is slidably installed on the inner wall of the auxiliary groove. The rotating pin 903 releases the limiting of the rotating locking rod 906 through the sliding limit rod 905, so that the stabilizing groove of the rotating locking rod 906 contacts the component platform 5 to form a limit, thereby further improving the stability of the device.

[0031] The main photovoltaic panel 3 is located on the movement trajectory of the rotating pin 903, the limiting pin groove 904 is located on the movement trajectory of the rotating pin 903, the triangular top block 907 is located on the movement trajectory of the rotating clamp rod 906, and the sliding limiting rod 905 is located on the movement trajectory of the rotating pin 903. A reset spring is provided between the triangular top block 907 and the component platform 5. The sliding limiting rod 905 is in contact with the inner wall of the rotating limiting groove. The component platform 5 is located on the movement trajectory of the stable clamp groove. A spiral spring is provided between the rotating pin 903 and the hydraulic top rod 902. The rebound force of the spiral spring can ensure that the rotating pin 903 is not horizontal before contacting the main photovoltaic panel 3, so that its subsequent rotation can drive the sliding limiting rod 905 to slide through the contact.

[0032] Two automatic rotating shafts 1001 are rotatably mounted on the side of the main photovoltaic panel 3. A secondary photovoltaic panel 4 is fixedly mounted on the circumference of each of the two automatic rotating shafts 1001. A universal top rod 1002 is rotatably mounted on the top of the component platform 5. A strip pin 1003 is slidably mounted on the bottom of the main photovoltaic panel 3. The top of the universal top rod 1002 is rotatably connected to the bottom of the strip pin 1003. A hinge 1004 is rotatably mounted on the bottom of the main photovoltaic panel 3. The end of the hinge 1004 away from the main photovoltaic panel 3 is rotatably connected to the bottom of the secondary photovoltaic panel 4. A horizontal pin groove 1005 is opened on the side of the hinge 1004. The secondary photovoltaic panel 4 can improve the power generation efficiency of the device under normal conditions. At the same time, it can be folded and stored in extreme weather conditions to reduce the surface area of ​​the total photovoltaic panel and its contact area with the wind. This improves the overall working efficiency of the device while enhancing its stability during operation.

[0033] A reciprocating hook 1006 is slidably installed on the right side of the hinge 1004, and a side hook 1007 is slidably installed on the top of the secondary photovoltaic panel 4. The limiting position formed between the reciprocating hook 1006 and the side hook 1007 can prevent the secondary photovoltaic panel 4 from being rotated again after being folded and stored, thereby preventing the secondary photovoltaic panel 4 from being rotated and opened again due to wind force after being folded.

[0034] The automatic rotating shaft 1001 is equipped with a spiral spring 3 inside. The strip pin 1003 contacts the inner wall of the horizontal pin groove 1005. The reciprocating hook 1006 is provided with a reset spring 2 between it and the hinge 1004. The reciprocating hook 1006 is located on the movement trajectory of the sub-photovoltaic panel 4, and the side hook 1007 is located on the movement trajectory of the reciprocating hook 1006. The spiral spring 3 of the automatic rotating shaft 1001 enables the sub-photovoltaic panel 4 to rotate and fold on its own under the rebound force of the spiral spring 3 after the limit between the strip pin 1003 and the horizontal pin groove 1005 is released.

[0035] During operation: When extreme winds occur at the location of the device, i.e., when the wind speed reaches a certain level, the wind force drives the anemometer 601 to rotate, which in turn drives the telescopic rod 602 to rotate as well. 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 rod 602 extends outward under the action of centrifugal force. During the rotation, the telescopic rod 602 contacts the deflection block 603, causing the deflection block 603 to deflect. This causes the bottom of the deflection block 603 to disengage from the fine hole. After disengagement, the main photovoltaic panel 3, the thick connecting rod, and the liquid... When the pressure rod 605 slides downwards under the action of gravity, the main photovoltaic panel 3 slides downwards when the wind speed reaches a certain level, thereby lowering the center of gravity of the entire device and improving the overall stability of the device. At the same time, during the descent, the main photovoltaic panel 3 drives the telescopic limit rod 607 to slide downwards together and contact the side top rod 606. After contact, the telescopic limit rod 607 retracts, thereby releasing the restriction between the main photovoltaic panel 3 and the thick connecting rod. Under the rebound force of the first spiral spring, the main photovoltaic panel 3 returns to the horizontal position, thereby reducing the angle between the photovoltaic panel and the wind and further improving the overall stability of the device.

[0036] As the hydraulic rod 605 slides downwards, it compresses the hydraulic oil inside the inner hydraulic cylinder, thereby driving the hydraulic push rod 902 to slide upwards. During this upward sliding, the top of the hydraulic push rod 902 contacts the bottom of the main photovoltaic panel 3 and supports it, thus improving the stability of the main photovoltaic panel 3 after it is lowered. Simultaneously, as the hydraulic push rod 902 slides upwards, it also drives the rotating pin 903 to slide upwards. After sliding a certain distance, the rotating pin 903 contacts the bottom of the main photovoltaic panel 3, causing it to rotate while sliding. During this rotation, the rotating pin 903 contacts the limiting pin groove 904, forming a limit. Simultaneously, during rotation, the rotating pin 903 contacts the sliding limit rod 905. When the sliding limit rod 905 slides, it disengages from the rotation limit groove of the rotating clamp rod 906 and releases the limiting effect of the rotating clamp rod 906. Under the action of gravity, the rotating clamp rod 906 rotates downward and contacts the triangular top block 907, causing the triangular top block 907 to retract into the component platform 5. After the triangular top block 907 continues to rotate, it disengages from the triangular top block 907 and, under the rebound force of the return spring, the triangular top block 907 re-extends from the component platform 5, thus achieving the limitation of the rotating clamp rod 906. After the rotating clamp rod 906 rotates downward, the stable groove contacts the component platform 5 and forms a limitation, thereby further improving the overall stability of the device after the main photovoltaic panel 3 is lowered.

[0037] Since the top of the universal top rod 1002 is rotatably connected to the bottom of the strip pin 1003 and the strip pin 1003 is slidably installed at the bottom of the main photovoltaic panel 3, the universal top rod 1002 rotates during the downward sliding of the main photovoltaic panel 3, thereby causing the strip pin 1003 to slide. After the strip pin 1003 slides, it disengages from the horizontal pin groove 1005. After disengagement, the limiting between the strip pin 1003 and the horizontal pin groove 1005 is released, allowing the auxiliary photovoltaic panel 4 to rotate under the rebound force of the spiral spring three of the automatic rotating shaft 1001. This enables the auxiliary photovoltaic panel 4 to rotate and fold after the main photovoltaic panel 3 is lowered, reducing the overall surface area of ​​the photovoltaic panel and the surface area in contact with the wind, thereby reducing the impact of wind on the overall device. As the secondary photovoltaic panel 4 rotates, it drives the side hook 1007 to rotate as well. 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 causes it to slide. During the sliding process, the reciprocating hook 1006 forms a limit with the side hook 1007, thereby preventing the secondary photovoltaic panel 4 from being blown open again due to excessive wind force after the photovoltaic panel has been folded. This further ensures the protective stability of the device in truly extreme environments.
