Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and specifically to a new energy photovoltaic device and a monitoring system. Background Art

[0002] With the development of technology and the continuous exploration and utilization of energy by people, solar power generation has become a very common way to utilize solar energy in our lives. During the process of solar power generation, photovoltaic panels are required to collect solar energy and then convert it into electrical energy for storage and utilization. After the existing devices are installed, it is difficult to adjust the tilt angle of the photovoltaic panels, so it is impossible to ensure that the photovoltaic panels face the sun for a long time, affecting the power generation efficiency of the photovoltaic panels.

[0003] The patent document with the existing publication number CN218829738U discloses a photovoltaic panel energy storage device capable of automatically adjusting the angle, including a support assembly. The support assembly includes a first support plate. A plurality of support columns are fixedly arranged on the upper surface of the first support plate in a circular array. The upper end surfaces of the support columns are fixedly provided with a second support plate. A transmission assembly is arranged on the upper surface of the second support plate. A semi-cylindrical body two is fixedly arranged in the middle of the upper surface of the second support plate. A retaining ring is fixedly arranged on the upper end surface of the semi-cylindrical body two. A photovoltaic energy storage assembly is arranged above the retaining ring.

[0004] However, the above device has the following problems when in use: Although most existing photovoltaic devices already have the function of adjusting the angle of the photovoltaic panel according to the incident angle of the sun, in most outdoor-installed photovoltaic systems, the driving devices for angle adjustment are usually exposed to the external environment for a long time. In this case, they will be affected by sand, wind, rain, sunlight, and temperature changes. Long-term environmental erosion may cause the gradual wear of the equipment, affecting the stability and continuity of the angle adjustment function of the photovoltaic panel; in addition, the large area of the photovoltaic panel makes it vulnerable to continuous pressure under the action of wind. If the wind force exceeds a certain limit, it may cause damage to the photovoltaic panel or its support structure, affecting the stability and safety of the entire photovoltaic system.

DETAILED DESCRIPTION OF THE INVENTION

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0028] Please refer to Figures 1 to 7 , a new energy photovoltaic device and monitoring system, including a bottom plate 1 and a mounting plate 3. A bracket 4 is fixedly installed on the mounting plate 3, and a photovoltaic panel 5 is installed on the bracket 4. The photovoltaic panel 5 can convert solar energy signals into electrical signals, thereby realizing the utilization of energy.

[0029] By rotating the mounting plate 3, the angle of the photovoltaic panel 5 thereon can be changed, thereby realizing the angle adjustment of the photovoltaic device.

[0030] A support frame 2 is fixedly installed on the bottom plate 1, and the mounting plate 3 is rotatably installed on the support frame 2. A connecting frame 10 is fixedly installed on the rotating rod 9, and the connecting frame 10 is fixedly connected to the mounting plate 3; By rotating the rotating rod 9, the connecting frame 10 will rotate synchronously. Since the connecting frame 10 is fixedly connected to the mounting plate 3, the angle of the mounting plate 3 can be changed, thereby completing the angle adjustment of the photovoltaic panel 5.

[0031] A fixing plate 6 is fixedly installed on the support frame 2, a shielding cover 8 is fixedly installed on the fixing plate 6, a driving plate 18 is fixedly installed at one end of the shielding cover 8 away from the fixing plate 6, and sliding blocks 19 are fixedly installed on both sides of the driving plate 18; The presence of the shielding cover 8 can shield the transmission parts and electrical components, thereby avoiding the influence of environmental factors on the normal operation of the equipment.

[0032] An iron ring 20 is inlaid on the driving plate 18, a connecting plate 11 is fixedly installed on the mounting plate 3, and a magnetic ring 25 adapted to the iron ring 20 is fixedly installed at the corresponding position on the connecting plate 11; When the shielding cover 8 is stretched to the corresponding height, the driving plate 18 will be inside the connecting plate 11. At this time, the iron ring 20 can be magnetically attracted to the magnetic ring 25, thereby completing the installation and fixing of the shielding cover 8. Subsequently, the connection part needs to be sealed to ensure that the space inside the shielding cover 8 is a sealed space, further protecting the equipment.

[0033] An air pump 16 and a pressure sensor 17 are arranged on the fixing plate 6.

[0034] It should be noted that the rotating rod 9, the transmission shaft 13, the servo motor 15, the driving gear 14, the driven gear 12, the air pump 16, and the air pressure sensor 17 are all inside the enclosed space formed by the fixing plate 6, the shielding cover 8, and the connecting plate 11. By enclosing the inside of the shielding cover 8 to form an enclosed space, if gas is input into the shielding cover 8 through the air pump 16, on the one hand, the air pressure inside can be changed, and the air pressure sensor 17 can detect the air pressure inside the shielding cover 8. Once there is a breakage, the pressure detected by the air pressure sensor 17 will change. Thus, the state of the shielding cover 8 can be determined through the air pressure sensor 17, facilitating the timely monitoring of the state of the shielding cover 8.

[0035] In the present invention, a servo motor 15 is fixedly installed on the support frame 2. A transmission shaft 13 is fixedly installed on the shaft output end of the servo motor 15. A driving gear 14 is fixedly installed on the transmission shaft 13. A driven gear 12 meshing with the driving gear 14 is fixedly installed on the rotating rod 9.

[0036] It should be noted that when the servo motor 15 is started, the transmission shaft 13 drives the driving gear 14 to rotate. Since the driving gear 14 meshes with the driven gear 12, the rotating rod 9 is driven to rotate through the driven gear 12. Then, the connecting frame 10 will rotate synchronously, enabling the installation plate 3 to change its angle, thereby realizing the adjustment of the angle of the photovoltaic panel 5.

[0037] In the present invention, convex blocks 7 are fixedly installed at both ends of the fixing plate 6. A fixing strip 21 is fixedly installed on the convex block 7. A rotating block 22 is fixedly installed on the fixing strip 21. A rotating strip 23 is rotatably installed on the rotating block 22. Sliding grooves 24 for the slider 19 to slide are provided on both the fixing strip 21 and the rotating strip 23.

[0038] It should be noted that when the installation plate 3 is in a state parallel to the bottom plate 1, at this time, the fixing strip 21 and the rotating strip 23 are also in a parallel state. The sliding groove 24 on the rotating strip 23 is on the extension line of the sliding groove 24 on the fixing strip 21. The slider 19 can move on the sliding groove 24, enabling the driving plate 18 to move along a predetermined trajectory. Thus, the enclosed space for accommodating mechanical equipment and electrical components can be closed and unfolded, facilitating the maintenance of mechanical components.

[0039] In the present invention, an installation cavity 26 is provided on the connecting plate 11. The end of the rotating strip 23 away from the fixing strip 21 is fixedly installed inside the installation cavity 26.

[0040] It should be noted that since the end of the rotating strip 23 is inside the connecting plate 11, when the slider 19 moves to the end of the rotating strip 23, the driving plate 18 will automatically be inside the connecting plate 11, facilitating the automatic docking of the iron ring 20 and the magnetic ring 25.

[0041] It should be noted that when the fixed bar 21 is parallel to the rotating bar 23, the distance between the sliding groove 24 on the fixed bar 21 and the sliding groove 24 on the rotating bar 23 is less than the length of the slider 19; since the length of the slider 19 is greater than the distance between the sliding groove 24 on the fixed bar 21 and the sliding groove 24 on the rotating bar 23, the slider 19 can slide smoothly at the connection, ensuring the continuity of the motion state of the slider 19.

[0042] In the present invention, the gap between the connecting plate 11 and the driving plate 18 is filled with a sealing strip 27. Through the arrangement of the sealing strip 27, the sealing performance can be ensured, the internal shielding cover 8 can be kept in a sealed state, the accidental influence of environmental factors such as dust and water vapor on the normal operation of the photovoltaic device can be reduced, and the sealing performance monitoring activity can also be facilitated.

[0043] It should be noted that the center of the rotating rod 9 and the center of the rotating block 22 are on the same straight line. When the rotating rod 9 rotates, the rotating block 22 can be rotated synchronously, and the connecting frame 10 always remains parallel to the rotating bar 23, ensuring the stable bending movement of the shielding cover 8.

[0044] It should be noted that the shielding cover 8 is made of an elastic material, and it is provided with accordion-like folds. Preferably, the material of the shielding cover 8 includes but is not limited to silicone; the elastic material enables the shielding cover 8 to synchronously adjust its own angle with the change of the angle of the connecting frame 10 driven by the rotating bar 23. The arrangement of the accordion-like folds enables a larger range of change in the height of the shielding cover 8, enabling the transmission device and electrical components to be in an exposed state, facilitating the maintenance activity; by enclosing these transmission parts and electrical components inside the shielding cover 8, the shielding cover 8 can shield them, thereby reducing the influence of environmental factors on the normal operation of the equipment.

[0045] The working process of the present invention: First, install the photovoltaic device at a suitable position. Through the photovoltaic panel 5, the conversion of solar energy signal into an electrical signal can be realized, thereby realizing the utilization of energy.

[0046] When the mounting plate 3 is in a state parallel to the bottom plate 1, at this time, the fixing strip 21 and the rotating strip 23 are also in a parallel state, and the chute 24 on the rotating strip 23 is on the extension line of the chute 24 on the fixing strip 21. The slider 19 can move on the chute 24, which can make the driving plate 18 move along a predetermined trajectory. Since the end of the rotating strip 23 is inside the connecting plate 11, when the slider 19 moves to the end of the rotating strip 23, the driving plate 18 automatically lies inside the connecting plate 11, facilitating the automatic docking activity of the iron ring 20 and the magnetic ring 25. The iron ring 20 can be magnetically attracted to the magnetic ring 25, thus completing the installation and fixation activity of the shielding cover 8. Subsequently, the connection part is sealed by the sealing strip 27 to ensure that the space inside the shielding cover 8 is a sealed space to protect the transmission part and electrical components.

[0047] When the angle needs to be adjusted, the transmission shaft 13 drives the driving gear 14 to rotate. The driving gear 14 meshes with the driven gear 12, and the rotating rod 9 is driven to rotate by the driven gear 12. Then the connecting frame 10 will rotate synchronously to change the angle of the mounting plate 3, realizing the adjustment of the angle of the photovoltaic panel 5.

[0048] By controlling the air pump 16 to input gas into the shielding cover 8 to keep a certain air pressure inside the shielding cover 8, the air pressure sensor 17 can monitor the air pressure inside the shielding cover 8. Once the shielding cover 8 is damaged, the air pressure detected by the air pressure sensor 17 will change, and then the state of the shielding cover 8 can be determined, facilitating timely obtaining of the air pressure state inside the shielding cover 8 and convenient maintenance of the shielding cover 8.

[0049] When maintenance is required, the mounting plate 3 is made parallel to the bottom plate 1, and then the sealing strip 27 is removed. The driving plate 18 is moved downward, and the slider 19 is moved on the chute 24. The driving plate 18 moves downward along a predetermined trajectory, so that the space inside the shielding cover 8 is exposed, and the transmission part and electrical components inside can be maintained.

[0050] In the present invention, the present invention includes an intelligent monitoring platform, and the intelligent monitoring platform includes a sensing and acquisition module, a monitoring and analysis module, a database, and an angle control module; The sensing and acquisition module is used to collect the external environment information of the photovoltaic device; The database is used to access and store the external environment information of the photovoltaic device; The monitoring and analysis module is used to analyze the external environment information of the photovoltaic device to obtain the wind force influence value, heat influence value, temperature and humidity influence value, and angle adjustment value; normalize the wind force influence value, heat influence value, and temperature and humidity influence value, and use the formula YX = FG * x1 + RL * x2 + WS * x3 to obtain the adjustment value YX; where x1, x2, and x3 respectively represent the weights corresponding to the wind force influence value, heat influence value, and temperature and humidity influence value; compare the adjustment value with its adjustment threshold, and if the adjustment value is greater than its adjustment threshold, generate an angle adjustment signal; it is also used to analyze the optimal angle of the photovoltaic panel 5 to obtain an angle control signal group; The angle control module controls the tilt angle of the photovoltaic panel 5 according to the angle control signal group, specifically: When receiving the angle tolerance signal, control the servo motor 15 to adjust the tilt angle of the photovoltaic panel 5 according to the tolerable angle; When receiving the angle adjustable signal, control the servo motor 15 to adjust the tilt angle of the photovoltaic panel 5 according to the angle adjustment value; When receiving the wind force overload signal, control the servo motor 15 to adjust the tilt angle of the photovoltaic panel 5 to the optimal tolerable angle.
