[0001] This invention relates to the field of monitoring technology, and in particular to an intelligent monitoring device for photovoltaic power plants. Background Technology

[0002] A photovoltaic power station is a power generation system that utilizes solar energy and is composed of special materials such as crystalline silicon panels and electronic components such as inverters. It is connected to the power grid and transmits electricity to the grid. Typically, when building a photovoltaic power station, dozens to hundreds of photovoltaic panel assemblies are set up side by side, which may stretch for tens or even hundreds of meters.

[0010] Optionally, two sets of strip frames are slidably arranged on both sides of the interior of the movable seat in conjunction with the vertical guide rod. A lifting rod is fixedly arranged at the top center of the strip frame, and a lifting ring is fixedly arranged at the top of the lifting rod through the top of the movable seat.

[0011] Optionally, a worm gear is rotatably mounted inside the inner transmission frame. The rear end of the worm gear is driven by a first motor, and the front end of the worm gear passes through the inner transmission frame and is fixedly mounted with an external transmission gear. A cleaning wheel and an external driven gear are coaxially rotatably mounted at the front end of the inner transmission frame, and the external transmission gear meshes with the external driven gear. The external brush structure of the cleaning wheel can contact the tooth surface of the intermediate rack. During the rotation of the worm gear, the external transmission gear is driven to rotate, and the external transmission gear drives the external driven gear and the cleaning wheel to rotate. The cleaning wheel is used to rotate and clean the surface of the intermediate rack, preventing foreign objects from falling on the top of the intermediate rack and affecting the movement of the moving seat.

[0012] Optionally, an inner drive shaft is rotatably arranged inside the inner drive frame, and a worm gear is fixedly arranged outside the inner drive shaft, which is connected to the worm gear in a drive connection; an inner drive gear is fixedly arranged outside the inner drive shaft; an inner driven shaft is rotatably arranged below the inner drive frame, and an inner driven gear and a traveling gear are fixedly arranged outside the inner driven shaft, with the inner driven gear meshing with the inner drive gear; the traveling gear meshes with the intermediate rack.

The H-shaped wheel slides against the outside of the lifting ring. During the rotation of the inner transmission shaft, the drive wheel and eccentric rod are driven to rotate. The eccentric rod drives the strip frame to reciprocate up and down, which in turn drives the lifting ring to move up and down. The lifting ring drives the H-shaped wheel to move up and down, and at the same time, the linkage rod drives the L-shaped rack to reciprocate up and down. The L-shaped rack drives the swing gear to rotate back and forth, thereby realizing the up and down swing of the monitor.

[0016] The beneficial effects are as follows:

This allows for more detailed observation of the swing monitor, enabling direct magnification of the monitor image for detection. It avoids the inability to observe important information due to small pixels and is sufficient for overall observation and detection.

[0018] 2. A second motor is provided, which provides dual observation function for the front and back of the photovoltaic module. When the moving base moves to the limit position, the second motor is started by the program to drive the bevel gear ring and the steering tube shaft to rotate half a turn. The self-locking ring and the locking block assist in positioning, so that the monitor faces the back of the photovoltaic module, and then the moving base moves in the opposite direction to monitor the back of the photovoltaic module.

[0019] 3. The cleaning wheel is provided to clean the track. Obstacles may fall from the top of the middle rack, affecting the movement of the moving seat. During the rotation of the worm gear, the external transmission gear is driven to rotate, which in turn drives the external driven gear and the cleaning wheel to rotate. The cleaning wheel is used to rotate and clean the surface of the middle rack, preventing foreign objects from falling on the top of the middle rack and affecting the movement of the moving seat.

[0031] Example 1: Please refer to the accompanying drawings in the instruction manual. Figures 1 to 8 As shown:

[0032] This invention proposes an intelligent monitoring device for a photovoltaic power station, comprising a mobile base 1, a control box 101 fixedly mounted at the rear end of the mobile base 1; an inner transmission frame 2 fixedly mounted on the upper part of the interior of the mobile base 1; a bearing seat 102 fixedly mounted on the top of the mobile base 1, and a steering tube shaft 3 rotatably mounted on the top of the bearing seat 102 in conjunction with the bearing; a second motor 4 fixedly mounted on the top of the control box 101; a transmission chamber 5 fixedly mounted on the top of the steering tube shaft 3; a monitor 6, a rotating tube shaft 601 for threading wires fixedly mounted on one side of the monitor 6, and the rotating tube shaft 601 rotatably mounted on one side of the transmission chamber 5; a guide rail 8, a central rack 9 fixedly mounted in the middle of the guide rail 8; F-shaped structures on both sides of the top of the guide rail 8; and guide wheels 104 rotatably mounted on both sides of the bottom of the mobile base 1, the guide wheels 104 slidingly mounted at the F-shaped structure of the guide rail 8.

[0033] Among them, the top two sides of the bearing housing 102 are integrally provided with protruding structures, and a locking block 103 is slidably provided in the middle of the protruding structure in conjunction with a spring rod. The spring rod is a hexagonal rod, which can maintain the sliding direction and ensure the main body state of the locking block 103. A self-locking ring 304 is fixedly provided on the lower outer side of the steering tube shaft 3. Two sets of V-shaped grooves that match the locking block 103 are opened on both sides of the self-locking ring 304.

[0034] The movable seat 1 has two sets of strip frames 105 that slide together with vertical guide rods on both sides inside. A lifting rod 106 is fixedly installed at the top center of the strip frame 105. A lifting ring 107 is fixedly installed at the top of the movable seat 1 through the top of the lifting rod 106.

[0035] The inner transmission frame 2 has a worm gear 201 that rotates inside. The rear end of the worm gear 201 is driven by a first motor 202. The front end of the worm gear 201 passes through the inner transmission frame 2 and is fixedly mounted with an outer transmission gear 203. The front end of the inner transmission frame 2 is coaxially mounted with a sweeping wheel 212 and an outer driven gear 213. The outer transmission gear 203 meshes with the outer driven gear 213. The external brush structure of the sweeping wheel 212 can contact the tooth surface of the intermediate rack 9.

[0036] The inner transmission frame 2 has an inner transmission shaft 204 rotatably mounted inside, and a worm gear 205 is fixedly mounted outside the inner transmission shaft 204. The worm gear 205 is connected to the worm 201 for transmission. An inner transmission gear 206 is fixedly mounted outside the inner transmission shaft 204. An inner driven shaft 207 is rotatably mounted below the inner transmission frame 2. An inner driven gear 208 and a traveling gear 209 are fixedly mounted outside the inner driven shaft 207. The inner driven gear 208 meshes with the inner transmission gear 206. The traveling gear 209 meshes with the intermediate rack 9.

[0037] Two sets of drive wheels 210 are fixedly installed at both ends of the inner drive shaft 204. An eccentric rod 211 is fixedly installed on the outside of the drive wheel 210. The eccentric rod 211 is slidably installed inside the strip frame 105.

[0038] Among them, an outer cylinder 301 is fixedly installed on the lower outer side of the steering tube shaft 3, a conical enclosure 302 is integrally installed on the upper outer side of the outer cylinder 301, and a bevel gear ring 303 is fixedly installed at the bottom of the outer cylinder 301; a bevel gear is installed at the shaft end of the second motor 4 to mesh with the bevel gear ring 303.

[0039] The transmission chamber 5 is equipped with an L-shaped rack 501 that slides with a vertical guide rod inside. The rotating tube shaft 601 is fixedly equipped with a swing gear 602, which meshes with the L-shaped rack 501. A linkage rod 7 is fixedly installed at the bottom of the L-shaped rack 501. An H-shaped wheel 701 is fixedly installed on the linkage rod 7, which passes through the bottom of the transmission chamber 5 and the top of the outer cylinder 301. The H-shaped wheel 701 slides against the outside of the lifting ring 107.

[0040] like Figure 1-8 As shown, the middle rack 9 provides a function to assist in movement;

[0041] When building a photovoltaic power station, dozens to hundreds of photovoltaic panel assemblies are set up side by side, which may stretch for tens or even hundreds of meters. Therefore, the guide rail 8 and the middle rack 9 are combined and pre-installed and fixed in the intervals of the row of photovoltaic power stations, while keeping the guide rail 8 parallel to the arrangement of the photovoltaic panels.

[0042] Worm gear 205 and worm 201 are common mechanical transmission devices, typically used for rotation and motion transmission. To determine the rotation direction of worm 201, one can refer to the rotation direction of worm gear 205. The working principle of worm gear 205 and worm 201 is mutual meshing; the rotation of worm 201 causes the rotation of worm gear 205. Worm 201 is a long, helical shaft, usually with one or more threads, located at the center of the transmission system. The function of worm 201 is to generate rotational motion, which is transmitted to the meshing worm gear 205. Worm gear 205 is a helical gear whose teeth mesh with the threads of worm 201. Worm gear 205 is usually fixed in the mechanical system to facilitate motion transmission. The function of worm gear 205 is... The rotational motion of the worm 201 is converted into axial motion or vice versa. When the worm 201 rotates, its thread meshes with the gear of the worm wheel 205. Due to the shape of the thread and teeth, the rotation of the worm 201 causes the worm wheel 205 to move axially, or the axial movement of the worm wheel 205 causes the worm 201 to rotate. This meshing process converts rotational motion into axial motion or vice versa. The design of the worm 201 and worm wheel 205 provides a mechanical advantage, allowing the worm wheel 205 to easily drive the worm 201, but requiring greater force to drive the worm wheel 205 in the reverse direction. This makes the worm wheel 205 and worm 201 transmission system very suitable for applications requiring anti-reverse rotation, because when the force stops acting on the worm wheel 205, it is not easy for it to rotate back.

[0043] During the monitoring process, the main driving mechanism is to start the first motor 202 to drive the worm gear 201 to rotate. When the worm gear 201 rotates, it drives the worm wheel 205 to rotate. The worm wheel 205 drives the inner drive shaft 204 and the inner drive gear 206 to rotate. The inner drive gear 206 drives the inner driven gear 208 to rotate. The inner driven gear 208 drives the inner driven shaft 207 to rotate. The inner driven shaft 207 drives the travel gear 209 to rotate. In conjunction with the intermediate rack 9, a counter-thrust force is provided to drive the moving seat 1 to move forward as a whole for travel detection and inspection. When foreign objects or abnormalities are detected on the photovoltaic surface, an alarm is triggered.

[0044] Since the back of the photovoltaic panel may also malfunction, the surface of the photovoltaic module on one side is inspected when the moving seat 1 moves. When the moving seat 1 moves to the limit position, the second motor 4 is started by the program to drive the bevel ring 303 and the steering tube shaft 3 to rotate half a turn. The self-locking ring 304 cooperates with the locking block 103 to assist in positioning, so that the monitor 6 faces the back of the photovoltaic module, and then the moving seat 1 is moved in the opposite direction to monitor the back of the photovoltaic.

[0045] Example 2: Based on Example 1, such as Figure 6-7 As shown, the monitor 6 is set to swing. During the rotation of the inner drive shaft 204, the drive wheel 210 and the eccentric rod 211 are driven to rotate. The eccentric rod 211 drives the strip frame 105 to move up and down reciprocally. Then, the lifting rod 106 drives the lifting ring 107 to move up and down. The lifting ring 107 drives the H-shaped wheel 701 to move up and down. At the same time, the linkage rod 7 drives the L-shaped rack 501 to move up and down reciprocally. The L-shaped rack 501 drives the swing gear 602 to rotate back and forth, so as to realize the up and down swing of the monitor 6. The monitor 6 is used to monitor the surface of the photovoltaic panel.

[0046] The swing monitor 6 allows for more detailed observation. The image of the monitor 6 can be directly magnified for inspection, avoiding the inability to observe important information due to small pixels, and is sufficient for overall observation and inspection.

[0047] Example 3: Based on Example 1, such as Figure 7 As shown, the upper surface of the middle rack 9 is a toothed surface, and the outer part of the sweeping wheel 212 is a brush structure, which can sweep the upper surface of the middle rack 9; the sweeping wheel 212 is arranged horizontally, which can sweep the middle rack 9 horizontally.

[0048] The monitoring device starts up at regular intervals. Usually, the mobile seat 1 is charging and waiting at one end of the guide rail 8. Due to the intervals in the inspection, obstacles may fall from the top of the intermediate rack 9, affecting the movement of the mobile seat 1. During the rotation of the worm gear 201, the external transmission gear 203 is driven to rotate. The external transmission gear 203 drives the external driven gear 213 and the cleaning wheel 212 to rotate. The cleaning wheel 212 is used to rotate and clean the surface of the intermediate rack 9 to prevent foreign objects from falling on the top of the intermediate rack 9 and affecting the movement of the mobile seat 1.

[0049] Because the movable seat 1 moves at regular intervals, the record of debris falling on the top of the intermediate rack 9 is relatively low in a short period of time. Therefore, the cleaning wheel 212 is only set to one direction to ensure normal observation.

[0050] The specific usage and function of this embodiment: In this invention, when in use, the guide rail 8 and the intermediate rack 9 are combined and pre-installed and fixed in the intervals of a row of photovoltaic power stations;

[0051] The first motor 202 is started, which drives the worm gear 201 to rotate. The worm gear 201 drives the worm wheel 205 to rotate, which in turn drives the inner drive shaft 204 and the inner drive gear 206 to rotate. The inner drive gear 206 drives the inner driven gear 208 to rotate, which drives the inner driven shaft 207 to rotate. The inner driven shaft 207 drives the travel gear 209 to rotate, which, together with the intermediate rack 9, drives the moving seat 1 to move forward as a whole for movement monitoring.

[0052] During the rotation of the inner drive shaft 204, the drive wheel 210 and the eccentric rod 211 are driven to rotate. The eccentric rod 211 drives the strip frame 105 to move up and down reciprocally. In turn, the lifting rod 106 drives the lifting ring 107 to move up and down. The lifting ring 107 drives the H-shaped wheel 701 to move up and down. At the same time, the linkage rod 7 drives the L-shaped rack 501 to move up and down reciprocally. The L-shaped rack 501 drives the swing gear 602 to rotate back and forth, so as to realize the up and down swing of the monitor 6. The monitor 6 is used to monitor the surface of the photovoltaic panel.

[0053] The monitoring device starts up at regular intervals. Usually, the mobile seat 1 is charging and waiting at one end of the guide rail 8. Due to the intervals in the inspection, obstacles may fall from the top of the intermediate rack 9, affecting the movement of the mobile seat 1. During the rotation of the worm gear 201, the external transmission gear 203 is driven to rotate. The external transmission gear 203 drives the external driven gear 213 and the cleaning wheel 212 to rotate. The cleaning wheel 212 is used to rotate and clean the surface of the intermediate rack 9 to prevent foreign objects from falling on the top of the intermediate rack 9 and affecting the movement of the mobile seat 1.

[0054] When the moving seat 1 moves, it inspects the surface of the photovoltaic module on one side. When the moving seat 1 moves to the limit position, the second motor 4 is started by the program to drive the bevel ring 303 and the steering tube shaft 3 to rotate half a turn. The self-locking ring 304 cooperates with the locking block 103 to assist in positioning, so that the monitor 6 faces the back of the photovoltaic module, and then the moving seat 1 moves in the opposite direction to monitor the back of the photovoltaic module.
