Description

Technical Field

[0001] The present invention relates to the field of intelligent network fire prevention, and in particular to a photovoltaic power station plant area fire prevention equipment and a fire prevention system. Background Art

[0002] A photovoltaic power station refers to a power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. Depending on the installation location, photovoltaic power stations can be divided into ground-based photovoltaic power stations and distributed photovoltaic power stations. Ground-based photovoltaic power stations are usually built on vacant land such as deserts, Gobi, and tidal flats, and are large in scale; while distributed photovoltaic power stations are mainly installed on roofs, walls, and other locations of buildings. They are relatively small in scale but more flexible and diverse.

[0003] During the use of photovoltaic power stations, the materials of photovoltaic panels have a hot spot effect, which refers to the phenomenon that when some cells in the photovoltaic module are blocked or have defects, these cells will consume the energy generated by other normally working cells, resulting in local overheating. This phenomenon will cause the local temperature of the photovoltaic module to rise, thereby affecting the power generation efficiency and life of the entire photovoltaic system. There are many reasons for the hot spot effect of photovoltaic panels, such as dust, bird droppings and other obstructions covering the surface of the cells. Photovoltaic panels themselves are not flammable, but after the hot spot effect occurs, accumulated temperature points with temperatures as high as several hundred degrees may form on their surface, which can easily cause surrounding objects to burn, especially distributed photovoltaic power stations. Because distributed photovoltaic power stations are often built on buildings in human settlements, the probability of them coming into contact with combustible materials is also much greater. Therefore, photovoltaic power stations need to regularly inspect the surface of photovoltaic panels to ensure that the surface of photovoltaic panels is relatively clean, thereby reducing the possibility of fires caused by accumulated temperature of photovoltaic panels.

[0004] Traditional ground inspection methods, such as manual ground inspection or ground inspection device ground inspection, are not suitable for the inspection of photovoltaic power stations in many cases, because photovoltaic power stations are all facing upwards, and in many distributed photovoltaic power stations, their installation locations are difficult for personnel or ground inspection devices to inspect. There are also existing methods of using drones for inspection, but the existing methods often rely on personnel to operate drones for inspection. Due to the lack of suitable docking devices, drones can only roughly inspect the surface of photovoltaic panels, and their detection accuracy is often not high. Summary of the Invention

[0021] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0022] like Figures 1 to 9 As shown, the present invention provides a photovoltaic power station plant area fire prevention equipment, include: The UAV platform 1 includes a main body 11, a UAV support arm 12, a drive motor 13, and a flight blade 14. The UAV support arm 12 is evenly fixedly mounted on the main body 11. The end of the UAV support arm 12 is fixedly mounted with the drive motor 13. The drive shaft of the drive motor 13 is fixedly connected to the flight blade 14. A hanging plate 2 is fixedly mounted on the lower end of the main body 11. A connecting slide 3 is rotatably mounted on the lower end of the hanging plate 2. Connecting mechanisms 4 are mounted on both sides of the connecting slide 3. The scanning device 5 is arranged at the lower end of the connecting slide rail 3.

[0023] It should be noted that, in the process of inspecting the photovoltaic panels of the photovoltaic power station through the fire prevention equipment, the scanning device 5 hoisted below is used to inspect the photovoltaic panels through the drone platform 1. When the surface of the inspected photovoltaic panel is very clean, the drone platform 1 will drive the scanning device 5 to scan the next photovoltaic panel. When there is obvious debris on the surface of the photovoltaic panel, the drone platform 1 will directly report the scanning situation of the scanning device 5 to the operator. When the scanned surface of the photovoltaic panel is suspected of having debris, the drone platform 1 brings the scanning device 5 close to the photovoltaic panel suspected of having debris. During this process, the airflow generated by the flying blades 14 of the drone will blow strongly on the surface of the photovoltaic panel. During this process, if it is found that the suspected debris on the photovoltaic panel is still not removed, the entire fire prevention equipment can be docked on the photovoltaic panel through the connection mechanism 4, so that the scanning device 5 can accurately scan the surface of the photovoltaic panel, thereby solving the problem that the traditional drone inspection cannot approach the photovoltaic panel well and thus perform accurate inspection of the photovoltaic panel.

[0024] like Figures 1 to 5 As shown, the scanning device 5 includes a scanning slide rail 51, a scanning slider 52 is slidably connected to the scanning slide rail 51, and a scanning probe 53 is provided at the lower end of the scanning slider 52. The scanning slide rail 51 is slidably suspended in the connecting slide rail 3, and the connecting slide rail 3 is rotated to provide a first adjusting screw 54, and the connecting slide rail 3 is also fixedly provided with a first motor 55, and the output shaft of the first motor 55 is fixedly connected to the first adjusting screw 54. The scanning slide rail 51 is rotated to provide a second adjusting screw 56 and fixed to provide a second motor 57, and the output shaft of the second motor 57 is fixedly connected to the second adjusting screw 56.

[0025] It should be noted that in the process of accurately scanning the surface of the photovoltaic panel, the first motor 55 drives the rotation of the first adjusting screw 54, and the first adjusting screw 54 is threadedly connected to the scanning slide 51, so that the scanning slide 51 moves horizontally along the photovoltaic panel. The second motor 57 drives the rotation of the second adjusting screw 56, and the second adjusting screw 56 is threadedly connected to the scanning slider 52, so that the scanning slider 52 moves along the longitudinal direction of the photovoltaic panel with the scanning probe 53. When the scanning probe 53 moves from one end of the photovoltaic panel to the other end, the first motor 55 will drive the rotation of the first adjusting screw 54, thereby changing the horizontal position of the scanning probe 53 on the photovoltaic panel, and the second motor 57 will drive the second adjusting screw 56 to rotate in the opposite direction, so that the scanning probe 53 can effectively scan all positions on the photovoltaic panel.

[0026] like Figure 8 and Figure 9 As shown, the pitch of the first adjusting screw 54 is , the pitch of the second adjusting screw 56 is The main body 11 is provided with an information processing module. The length and width of the photovoltaic panel to be inspected are input into the information processing module, and the information processing module can adjust the pitch of the first adjusting screw 54 according to the length and width of the photovoltaic panel to be inspected. , the pitch of the second adjusting screw 56 , scanning width of scanning probe 53 , as well as the length and width of the photovoltaic panel, automatically generates the scanning path of the scanning probe 53, and is achieved by controlling the rotation of the first motor 55 and the second motor 57.

[0027] After completing the scanning of the photovoltaic panels, the information processing module can summarize the information on the photovoltaic panels and upload the information to the operator.

[0028] like Figure 8 As shown, the length and width of the photovoltaic panel are and When the scanning probe 53 scans the photovoltaic panel, the scanning route is a straight line parallel to the photovoltaic panel. and In contrast, the number of scans required is ,Will and Compare the number of times the first motor 55 rotates each time a scan is performed ,Will and Compare the number of times the second motor 57 rotates during one scan .

[0029] It should be noted that whenever the first motor 55 drives the first adjusting screw 54 to rotate When the scanning rail 51 moves horizontally along the photovoltaic panel, the distance is In this way, when the scanning probe 53 scans the photovoltaic panel, the boundaries of each scanning position are all connected, so there will be no omission of the scanning position during the scanning process. In each scanning process, the second motor 57 drives the second adjusting screw 56 to rotate the number of times. After completing a scan, the first motor 55 drives the first adjusting screw 54 to rotate, thereby changing the lateral position of the scanning probe 53. Then the second motor 57 drives the second adjusting screw 56 to rotate in the opposite direction, so that the scanning route can be realized in a straight line parallel to the photovoltaic panel.

[0030] like Figure 9 As shown, in the process of scanning the photovoltaic panel, the scanning route is zigzag, and the width of the photovoltaic panel is The pitch of the first adjusting screw 54 By comparison, the number of turns of the first adjustment screw 54 is obtained when the photovoltaic panel is scanned as a whole. ,Will and The number of turns required for the second adjusting screw 56 to perform a horizontal scan of the photovoltaic panel is obtained by comparing the number of turns required for the second adjusting screw 56 to perform a horizontal scan of the photovoltaic panel. , the speed of the first motor 55 is set to , and Compare and get the coverage factor , the speed of the second motor 57 is , which should satisfy the relationship .

[0031] It should be noted that, through the above technical solution, the rotation of the first motor 55 and the rotation of the second motor 57 are synchronized during the scanning of the photovoltaic panel. This has the advantage of significantly improving the efficiency of the scanning. At the same time, whenever the scanning probe 53 moves from one end of the photovoltaic panel to the other end of the photovoltaic panel, the second motor 57 drives the second adjusting screw 56 to rotate in the opposite direction. During this process, the relationship should be satisfied. The purpose is to make the previous or next scanning process well connected or overlapped, so that no scanning position is missed.

[0032] The regional distribution map of photovoltaic panels is stored in advance in the information processing module. When the fire protection equipment scans the photovoltaic panels, each photovoltaic panel will be numbered and marked at the location of the photovoltaic panel in the regional distribution map. In the process of scanning the photovoltaic panels, each horizontal scan will form an independent scanning area and number it.

[0033] It should be noted that, through the above technical solution, when debris is detected condensing on the photovoltaic panel, the number of the photovoltaic panel and the number of the location of the debris will be uploaded to the operator. The advantage of this is that the exact location of the debris can be found quickly.

[0034] like Figure 2 and Figure 5 As shown, the scanning probe 53 is mounted on the scanning slider 52 via a telescopic rod 6 , the fixed end of the telescopic rod 6 is fixedly mounted on the scanning slider 52 , and the scanning probe 53 is fixedly mounted at the end of the telescopic end of the telescopic rod 6 .

[0035] It should be noted that the extension and retraction of the telescopic rod 6 can effectively change the distance between the scanning probe 53 and the photovoltaic panel, thereby changing the scanning width of the scanning probe 53. In this way, when the surface of the photovoltaic panel is relatively smooth, the distance between the scanning probe 53 and the photovoltaic panel can be increased, thereby increasing value, thereby increasing the efficiency of the work. When there are a lot of debris on the surface of the photovoltaic panel, the distance between the scanning probe 53 and the photovoltaic panel can be reduced, thereby improving the detection accuracy.

[0036] like Figure 1 and Figure 7 As shown, a balancing mechanism 7 is provided between the hoisting plate 2 and the connecting slide rail 3. The balancing mechanism 7 includes a horizontal measurement module 71 and a balancing hydraulic rod 72. The two ends of the balancing hydraulic rod 72 are rotatably connected to the hoisting plate 2 and the end of the connecting slide rail 3 respectively. The horizontal measurement module 71 is integrated and installed on the hoisting plate 2.

[0037] It should be noted that, in the process of accurately scanning the photovoltaic panels, if the UAV platform 1 can be docked at the upper end of the connecting slide rail 3 and the suspended state of the UAV platform 1 can be reduced, the endurance of the UAV platform 1 can be effectively improved. By pulling the UAV platform 1 by the balancing hydraulic rod 72 and determining the position of the UAV platform 1 by the extension and contraction of the balancing hydraulic rod 72, the UAV can be kept in a horizontal state, which is conducive to the UAV's take-off again, and the posture of the UAV platform 1 can be sensed through the horizontal measurement module 71.

[0038] like Figure 1 、 Figure 2 and Figure 5 As shown, the connecting mechanism 4 includes a sliding plate 41, a connecting plate 42, a pressing slide 43 and a splint 44. The sliding plate 41 is slidably connected to the two ends of the connecting slide rail 3. The sliding plate 41 is fixedly installed with a connecting plate 42. The connecting plate 42 is U-shaped. The connecting plate 42 is connected with a pressing slide 43 in an axial sliding manner with the connecting slide rail 3. The upper and lower ends of the connecting plate 42 are connected with a splint 44 in a slidable manner in a direction perpendicular to the axial direction of the connecting plate 42. A spring is fixedly connected between the pressing slide 43 and the middle section of the connecting plate 42. A pull rod is provided between the pressing slide 43 and the splint 44. The two ends of the pull rod are rotatably connected with the pressing slide 43 and the splint 44 respectively.

[0039] It should be noted that the sliding plate 41 can be pulled by the cylinder to make the two connecting plates 42 clamp the two sides of the photovoltaic panel. When the top pressing slide plate 43 contacts the photovoltaic panel, the top pressing slide plate 43 will slide relative to the connecting plate 42, thereby pulling the clamping plate 44 through the pull rod, and then the clamping plate 44 clamps the photovoltaic panel. In this way, under the joint action of the top pressing slide plate 43 and the clamping plate 44, the fire protection equipment can be fixedly installed on the photovoltaic panel.

[0040] The present invention also provides a photovoltaic power station plant area fire protection system, comprising the following steps: S1. When the scanning device 5 finds that the suspected debris on the photovoltaic panel has not been removed, the entire fire protection device can be docked on the photovoltaic panel through the connecting mechanism 4; S2. When the fire prevention equipment scans the photovoltaic panels, each photovoltaic panel will be numbered and marked on the location of the photovoltaic panel in the area distribution map. During the scanning process of the photovoltaic panels, each horizontal scan will form an independent scanning area and be numbered;

[0041] When debris is detected on a photovoltaic panel, the number of the photovoltaic panel and the location of the debris will be uploaded to the operator; S3. During the specific scanning process, the first motor 55 drives the first adjusting screw 54 to rotate, and the first adjusting screw 54 is threadedly connected to the scanning slide 51, so that the scanning slide 51 moves horizontally along the photovoltaic panel. The second motor 57 drives the second adjusting screw 56 to rotate, and the second adjusting screw 56 is threadedly connected to the scanning slider 52, so that the scanning slider 52 moves with the scanning probe 53 along the longitudinal direction of the photovoltaic panel. When the scanning probe 53 moves from one end of the photovoltaic panel to the other end, the first motor 55 will drive the first adjusting screw 54 to rotate, thereby changing the horizontal position of the scanning probe 53 on the photovoltaic panel, and the second motor 57 will drive the second adjusting screw 56 to rotate in the opposite direction, so that the scanning probe 53 can effectively scan all positions on the photovoltaic panel.

[0042] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.

The second motor (57) drives the second adjusting screw (56) to rotate in the opposite direction, so that the scanning probe (53) can effectively scan all positions on the photovoltaic cell panel.
