Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and particularly to a photovoltaic power generation system with complementary fishery and photovoltaic power generation. Background Art

[0002] Photovoltaic systems play an important role in many fields by directly converting sunlight into electrical energy. To improve the energy conversion efficiency of photovoltaic systems, an automatic tracking system is usually adopted to adjust the angle of photovoltaic panels so that they are as perpendicular as possible to the sun's rays, thereby maximizing the light energy absorption efficiency. One of the core components of such an automatic tracking system is an electric motor, which is responsible for driving the photovoltaic panels to adjust the angle according to the position of the sun at different times of the day. In the face of adverse weather conditions, such as strong wind weather, the photovoltaic panels and their supporting structures face additional pressure and risks. Due to the large area of the photovoltaic panels, they are prone to being the force-receiving surface of the wind force, which may cause a large torque on the output shaft connected to the electric motor. At the same time, the large wind force on the photovoltaic panels themselves is also likely to cause damage, thereby affecting the service life of the electric motor and the photovoltaic panels. Summary of the Invention

[0003] To solve the above problems, the present invention provides a photovoltaic power generation system with complementary fishery and photovoltaic power generation, including a base. A motor is fixedly arranged on the base. Two mounting plates are fixedly arranged on the top surface of the base. Mounting holes are arranged in both of the two mounting plates. A rotating shaft is rotatably arranged in the two mounting holes. A photovoltaic panel is fixedly arranged on the rotating shaft. A separating and combining device capable of disconnecting or connecting the rotating shaft and the output shaft of the motor is arranged between the rotating shaft and the output shaft of the motor. A triggering device and a flipping device are also arranged between the rotating shaft and the motor. When the photovoltaic panel is subjected to a large wind force, the triggering device is activated to drive the separating and combining device to disconnect the rotating shaft from the output shaft of the motor, and then drive the flipping device to flip the photovoltaic panel to a direction close to the horizontal direction.

[0004] The separating and combining device includes a movable space arranged on the end face of the output shaft of the motor. A limit block capable of reciprocating is arranged in the movable space. A first spring is fixedly arranged between the limit block and the inner wall of the movable space. A spline is fixedly arranged on the limit block. A spline groove is arranged at one end of the rotating shaft close to the spline.

[0005] The triggering device includes two movable shells arranged on the front and rear sides of the rotating shaft. A working groove is arranged on the side surface of each movable shell facing away from the rotating shaft. A windward plate is arranged outside the working groove. A strip magnet capable of reciprocating and passing through the working groove is arranged in the working groove. The windward plate is connected to the strip magnet. An annular magnet is fixedly arranged on the limit block. When the strip magnet faces the annular magnet, the magnetic poles of the opposite side surfaces of the two are the same.

[0006] An intermediate component for connecting the windward plate and the strip magnet is provided between the windward plate and the strip magnet. The intermediate component includes a movable block that can reciprocate in the working groove. One end of the movable block is fixedly connected to the wind deflector. A second spring is fixedly arranged between the end of the movable block located inside the working groove and the inner wall of the working groove. The other end of the movable block is fixedly connected to the strip magnet. An annular magnet is fixedly arranged on the rotating shaft. When the strip magnet faces the annular magnet, the magnetic poles on the opposite side surfaces of the two are the same.

[0007] On one side surface of each movable housing facing the rotating shaft, a rack is fixedly arranged. A large gear is fixedly arranged on the rotating shaft. A rotating shaft is rotatably arranged between each rack and the large gear. A small gear that cooperates with the rack and the large gear is fixedly arranged on each rotating shaft.

[0008] Two abutting rods are evenly distributed along the circumferential direction on the rotating shaft. An abutting column is fixedly arranged on each of the two movable housings. One abutting column is located above the movable housing, and the other abutting column is located below the movable housing.

[0009] A housing is fixedly arranged on the top surface of the base. The two ends of the rotating shaft are rotatably arranged between the inner walls of the housing. A first trapezoidal groove is arranged on the top wall of the housing. A first trapezoidal block that can reciprocate is arranged in the first trapezoidal groove. A second spring is fixedly arranged between the first trapezoidal block and the inner wall of the first trapezoidal groove. The first trapezoidal block is fixedly connected to one of the racks. A second trapezoidal groove is arranged on the top surface of the base. A second trapezoidal block that can reciprocate is arranged in the second trapezoidal groove. A third spring is fixedly arranged between the second trapezoidal block and the inner wall of the second trapezoidal groove. The second trapezoidal block is fixedly connected to the other rack.

[0010] The windward plate is arranged in a flared shape.

[0011] The beneficial effects of the present invention are as follows: 1. Through the setting of the triggering device, the separating and combining device, and the flipping device, when encountering a relatively strong wind, the output shaft of the rotating shaft and the motor can be disconnected, and then the flipping device is driven to flip the photovoltaic panel to a horizontal direction, so that the output shaft will not be subjected to a large torque due to excessive wind force, and at the same time, the wind force received by the photovoltaic panel is also reduced to the minimum, thereby being able to avoid damage to the motor used by the photovoltaic panel and the photovoltaic panel itself as much as possible due to a relatively strong wind, and thus extending the service life of the photovoltaic system.

[0012] 2. When the photovoltaic panel rotates to the horizontal direction, exactly the two abutting rods are also in the horizontal direction and abut against the abutting columns, so that it can be ensured that even when the photovoltaic panel is at any angle in the face of strong wind, it can be caught by the abutting columns and the abutting rods and will not continue to rotate when rotating to the horizontal direction, so that the photovoltaic panel is subjected to a smaller wind force in the horizontal direction, and thus damage to the photovoltaic panel under relatively strong wind force can be avoided as much as possible.

[0013] 3. The labor-saving structure set by the meshing of the small gear and the large gear enables the windward plate to have sufficient force to smoothly turn the photovoltaic panel when it is affected by the wind force. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In view of the problems existing in the prior art, an embodiment of the present invention provides a photovoltaic power generation system with complementary fishing and solar power, as Figures 1 to 8 shown, which includes a base 1. A motor 2 is fixedly arranged on the base 1. Two mounting plates 3 are fixedly arranged on the top surface of the base 1. Mounting holes 4 are arranged in both of the two mounting plates 3. A rotating shaft 5 is rotatably arranged in the two mounting holes 4. A photovoltaic panel 6 is fixedly arranged on the rotating shaft 5.

A triggering device and a flipping device are also arranged between the rotating shaft 5 and the motor 2. When the photovoltaic panel 6 is subjected to a relatively large wind force, the triggering device is activated to drive the separating and combining device to disconnect the rotating shaft 5 from the output shaft of the motor 2, and then drive the flipping device to flip the photovoltaic panel 6 to a horizontal direction. Two columns 100 are fixedly arranged on the bottom surface of the base 1, and the columns 100 are used to fix the photovoltaic panel above the river surface.

[0025] The separating and combining device includes a moving space 20 arranged on the end face of the output shaft of the motor 2. A limit block 21 capable of reciprocating movement is arranged in the moving space 20. A first spring 22 is fixedly arranged between the limit block 21 and the inner wall of the moving space 20.

[0026] The triggering device includes two moving shells 30 arranged on the front and rear sides of the rotating shaft 5. A working groove 31 is arranged on the side surface of each moving shell 30 facing away from the rotating shaft 5. A windward plate 33 is arranged outside the working groove 31. A strip magnet 35 capable of reciprocating movement and passing through the working groove 31 is arranged in the working groove. The windward plate 33 is connected to the strip magnet 35. An annular magnet 36 is fixedly arranged on the limit block 21. When the strip magnet 35 faces the annular magnet 36, the magnetic poles of the opposite side surfaces of the two are the same.

[0027] An intermediate component for connecting the windward plate 33 and the strip magnet 35 is provided therebetween. The intermediate component includes a movable block 32 that can reciprocate within the working groove 31. One end of the movable block 32 is fixedly connected to the wind deflector 33. A second spring 34 is fixedly provided between the end of the movable block 32 located inside the working groove 31 and the inner wall of the working groove 31. The other end of the movable block 32 is fixedly connected to the strip magnet 35. An annular magnet 36 is fixedly provided on the rotating shaft 5. When the strip magnet 35 faces the annular magnet 36, the magnetic poles on the opposite sides of the two are the same.

[0028] On one side surface of each movable housing 30 facing the rotating shaft 5, a rack 40 is fixedly provided. A large gear 41 is fixedly provided on the rotating shaft 5. A rotating shaft 42 is rotatably provided between each rack 40 and the large gear 41. A small gear 43 that cooperates with the rack 40 and the large gear 41 is fixedly provided on each rotating shaft 42 (when there is no strong wind, the rack 40 is away from the small gear 43 and is in a non-engaged state).

[0029] Through the setting of the small gear and the large gear, as a labor-saving structure, it can facilitate the windward plate to drive the photovoltaic panel to flip more smoothly when the windward plate is pushed by the wind. In this embodiment, the transmission ratio of the small gear to the large gear is 1:3.

[0030] Two abutting rods 50 are evenly distributed along the circumferential direction on the rotating shaft 5, and the rotating shaft 5 and the abutting rods 50 are fixedly connected. One abutting column 51 is fixedly provided on each of the two movable housings 30. One abutting column 51 is located above the movable housing 30, and the other abutting column 51 is located below the movable housing 30.

[0031] A housing 60 is fixedly provided on the top surface of the base 1. The two ends of the rotating shaft 42 are rotatably provided between the inner walls of the housing 60. A first trapezoidal groove is provided on the top wall of the housing 60. A first trapezoidal block 61 that can reciprocate is provided in the first trapezoidal groove. A second spring 62 is fixedly provided between the first trapezoidal block 61 and the inner wall of the first trapezoidal groove. The first trapezoidal block 61 is fixedly connected to one of the racks 40. A second trapezoidal groove is provided on the top surface of the base 1. A second trapezoidal block 63 that can reciprocate is provided in the second trapezoidal groove. A third spring 64 is fixedly provided between the second trapezoidal block 63 and the inner wall of the second trapezoidal groove. The second trapezoidal block 63 is fixedly connected to the other rack 40.

[0032] The windward plate 33 is arranged in a flared shape. Through this flared shape setting, the windward plate 33 can have a larger windward area, so that the windward plate can receive a greater wind force, which helps to flip the photovoltaic panel by pushing the windward plate.

[0033] Working principle: When the photovoltaic panel 6 is subjected to strong wind, the windward plate 33 will also be subjected to strong wind. Therefore, when the windward plate 33 is subjected to wind force, it will be pushed, causing the windward plate 33 to drive the movable block 32 and the strip magnet 35 to move in the direction close to the ring magnet 36. When the strip magnet 35 faces the ring magnet 36, due to the repulsion between like poles, it will push the spline 23, the ring magnet 36, the limit block 21 and the first spring 22 to move, causing the spline 23 to leave the spline groove 24, achieving the effect of disconnecting the output shaft of the motor from the photovoltaic panel (at this time, the rack and the pinion are still not engaged). When the windward plate 33 is continuously pushed, the windward plate 33 will drive the movable housing 30 and the rack 40 to move. At this time, the rack and the pinion start to engage, causing the rack 40 to push the pinion 43 to rotate. The pinion 43 drives the large gear 41 to rotate, and the large gear 41 drives the rotating shaft 5 and the photovoltaic panel 6 to tilt towards the horizontal direction. When the photovoltaic panel rotates to the horizontal direction, just the two abutting rods 50 are also in the horizontal direction and abut against the abutting column 51. Thus, it can be ensured that even when the photovoltaic panel 6 is at any angle in the face of strong wind, it can be stuck by the abutting column 51 and the abutting rod 50 and will not continue to rotate when it rotates to the horizontal direction, so that the photovoltaic panel 6 is subjected to less wind force in the horizontal direction, thereby minimizing the damage to the photovoltaic panel under strong wind.

[0034] When the strong wind disappears, under the action of the second spring 62, it will push the rack 40 to reset. The second spring 34 pushes the windward plate to reset. The spline 23 will also, under the reset action of the first spring 22, make the spline 23 re-enter the spline groove 24, reconnecting the output shaft of the motor to the photovoltaic panel, thus eliminating the need for manual reset.

[0035] Although the embodiments of the present invention have been described in detail above, it is obvious to those skilled in the art that various modifications and changes can be made to these embodiments. However, it should be understood that such modifications and changes are all within the scope and spirit of the present invention. Moreover, the present invention described herein may have other embodiments and can be implemented or realized in various ways.
