Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panels, and in particular to a protective device for new energy photovoltaic panels. Background Art

[0002] Photovoltaic power generation system is composed of solar cell array, battery pack, charge and discharge controller, inverter, AC distribution cabinet, solar tracking control system and other equipment. In actual use, photovoltaic panels are installed outdoors and facing the sun. In order to better receive light, there are generally no obstructions around the photovoltaic panels, and photovoltaic panels are generally installed at an angle. In windy weather, when the wind direction is opposite to the tilt direction of the photovoltaic panel, the wind direction also flows toward the lifted side. At this time, due to its tilted design, the contact area is increased, and the wind cannot be effectively diverted. The wind force will make the photovoltaic panel as a whole have an upward force, which will cause the risk of overturning. For this reason. We designed a protective device for new energy photovoltaic panels. Summary of the invention

[0045] Guide wire wheels 36 are provided at both ends of the winding shaft 35, and multiple guide wire wheels 36 are provided on the right side of the mounting frame 1. The belt 34 passes through the multiple guide wire wheels 36 in sequence and is connected to the driving mechanism 8.

During the deflection process, the deflection worm 7 will cause the deflection worm wheel 812 to rotate, which will cause the driving shaft 81 to rotate. The rotating driving shaft 81 will cause the movable pull seat 37 to move linearly back and forth, thereby enabling the cleaning plate 4 to move accordingly.

[0051] The reset structure 82 includes a fixed plate 821 rotatably connected to the drive shaft 81, a reset spring 822 is connected to the rear side of the fixed plate 821, and a movable push plate 823 is connected to one end of the reset spring 822 away from the fixed plate 821.

The driving rod 831 is threadedly connected with a moving plate 832 through the two-way thread 833. The head end of the driving rod 831 is also provided with a driving worm 834. The moving push plate 823 can push the moving plate 832 to move together when moving forward, and the moving plate 832 is threadedly connected to the driving rod 831, which can change the linear motion into a rotating motion, thereby rotating the driving rod 831. There is a certain distance between the moving push plate 823 and the moving plate 832, and the moving push plate 823 will contact it only after moving a certain distance, so that the side wind plate 6 will not move on the lifting frame 9 when the wind force is small;

The rotation of the transmission shaft 1 841 can make the transmission shaft 851 rotate accordingly, and then make the lifting gear 853 rotate, and the transmission ratio in the whole structure is adjusted by a certain proportion, so that when the side wind plate 6 is deflected by a corresponding angle, the whole lifting frame 9 can rise to a suitable position.

[0057] A connection notch is formed by removing a portion of the rear surface of the front frame 12, and the internal cavity of the front frame 12 is connected to the outside through the connection notch.

[0062] Working principle: The photovoltaic panel 2 is installed at a suitable position through the mounting frame 1. When encountering wind from front to back or from back to front (and the wind force is less than the set wind force), the side wind plate 6 will deflect backward or forward at this time. The forward or backward deflection of the side wind plate 6 will cause the deflection worm 7 at both ends to rotate, thereby enabling the two driving shafts 81 on both sides to rotate accordingly. Since the movable pull seat 37 is threadedly connected to the driving shaft 81, the movable pull seat 37 will move linearly toward the rear or front side;

[0063] When the movable pull seat 37 moves backward, the belt 34 will be wound onto the take-up wheel 32 under the action of the rewinding spring, so that the two cleaning plates 4 will swing forward, and when it moves forward, the belt 34 will be pulled backward, so that the cleaning plates 4 will move backward, so that the surface of the photovoltaic panel 2 can be cleaned accordingly, and because a part of the belt 34 will be wound around the take-up wheel 32, when the height of the photovoltaic panel 2 changes, the belt 34 can automatically compensate accordingly, so that it will not interfere with the normal operation;

[0064] By setting two groups of cleaning plates 4 above the photovoltaic panel 2, and the two cleaning plates 4 are located at 1 / 4 of the front and rear sides of the photovoltaic panel 2, and cooperating with the pulling mechanism 3, the pulling mechanism 3 enables the cleaning plates 4 to be displaced accordingly under the action of the side wind plate 6, thereby cleaning the surface of the photovoltaic panel 2 to prevent the accumulation of dust and debris from reducing its light conversion effect.

[0065] When the device encounters strong wind from the front to the back, the side wind plate 6 will deflect backwards, thereby reducing the wind resistance of the device as a whole, and the wind will flow upward along the surface of the photovoltaic panel 2, so that the photovoltaic panel 2 is subjected to a downward component force, and the photovoltaic panel 2 will not be overturned at this time;

[0066] When the device encounters a strong wind from the back to the front, the photovoltaic panel 2 will be subjected to an upward force component, which may cause the risk of overturning. At this time, the side wind plate 6 will be deflected forward by the wind force, and the side wind plate 6 deflected forward will make the driving shaft 81 rotate forward through the deflection worm 7 and the deflection worm wheel 812. Since the movable push plate 823 is threadedly connected with the driving shaft 81, the movable push plate 823 will move forward and compress the return spring 822.

[0067] When the wind hood 51 encounters a strong wind from the back to the front, it will be blown forward, and the lifting frame 9 will be unlocked at this time, so that it can move upward, and the moving push plate 823 will contact the moving plate 832 after moving a certain distance and make the moving plate 832 move forward, and the moving plate 832 moving forward will make the driving rod 831 rotate, and the rotation of the driving rod 831 can make the transmission shaft 1 841 rotate through the transmission worm gear 843 and the driving worm 834, and the rotation of the transmission shaft 1 841 can make the transmission shaft 2 851 rotate accordingly, and then can make the lifting gear 853 rotate, and the rotation of the lifting gear 853 will make the lifting frame 9 move upward, so that the entire photovoltaic panel 2 moves upward and is in a horizontal state, reducing the contact area with the wind and avoiding the risk of being overturned;

[0068] When the wind force decreases or even disappears, the elastic force of the return spring 822 is greater than the wind force, and the return spring 822 will make the movable push plate 823 move backward. After there is no thrust from the movable push plate 823, the lifting frame 9 will move downward under its own gravity, and in the process of moving downward, the transmission member 2 85 and the transmission member 1 84 will rotate accordingly and transmit to the driving structure 83, and the movable plate 832 will move in the opposite direction and reset, and the reverse reset of the movable push plate 823 will also reduce the swing angle of the side wind plate 6, or even return to the initial state;

[0069] By rotatably connecting the front side of the photovoltaic panel 2 to the lifting frame 9, and the lifting frame 9 to the driving mechanism 8, and the driving mechanism 8 to the side wind plate 6 through the deflection worm 7, in windy weather with a high wind force level, the deflection of the side wind plate 6 can move the front side of the photovoltaic panel 2 upward through the driving mechanism 8, so that the photovoltaic panel 2 is in a horizontal state as a whole, reducing the contact area of ​​the wind, avoiding it from being overturned, and improving safety.

[0070] In the present invention, a brush or a rubber scraper is arranged under the cleaning plate 4 for cleaning the surface of the photovoltaic panel 2, and in order to ensure that the device is not disturbed by external impurities, a corresponding protective shell can also be arranged at the position of the transmission component in the device (in order to make the transmission structure in the figure more obvious, the protective shell is not drawn in the figure).
