Description

Technical Field

[0001] This invention relates to the field of solar power generation technology, and more particularly to a solar photovoltaic power generation device suitable for coastal mudflats. Background Technology

[0002] Tidal flats are often underutilized idle land. Building photovoltaic power stations on tidal flats can avoid competing with agriculture, urban construction and other fields for valuable land resources. Moreover, coastal tidal flats have abundant sunshine resources. Some projects adopt salt-photovoltaic complementary or fishery-photovoltaic complementary models, which can restore the tidal flat ecosystem and promote biodiversity recovery while generating electricity.

[0003] However, the installation of photovoltaic equipment in tidal flat areas usually adopts the method of fixed connection with fixed piles and support frames. However, the coastal areas have strong winds and large areas of photovoltaic panels exposed to the wind, which requires extremely high strength and stability of the support structure. In severe weather such as rain, snow and hail, the photovoltaic panels can be damaged, causing huge economic losses. At the same time, the tidal flat foundation is soft, and the fixed piles may be slightly displaced or shaken under long-term load and water erosion, causing the photovoltaic panels to tilt and reduce power generation efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a solar photovoltaic power generation device suitable for coastal mudflats, solving the problems mentioned in the background art where photovoltaic panels are damaged in severe weather, and where slight displacement or shaking of the fixing piles causes the photovoltaic panels to tilt, reducing power generation efficiency and causing huge economic losses.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A solar photovoltaic power generation device suitable for coastal mudflats includes: an installation frame and fixed piles, wherein a central bearing frame is provided on the installation frame, and a top flip plate and a bottom flip plate are rotatably connected to both ends of the central bearing frame, and photovoltaic panels are provided on the central bearing frame, the top flip plate and the bottom flip plate. The wind-resistant protection unit is installed on the mounting frame and the central load-bearing frame, and includes a plurality of first hydraulic push rods for preventing damage to the photovoltaic panels in severe weather. An adaptive leveling unit is disposed between the mounting frame and the fixed pile. The adaptive leveling unit is used to automatically adjust the floating leveling plate that causes the photovoltaic panel to tilt due to the shaking of the fixed pile.

[0006] Furthermore, both ends of the mounting frame are fixedly connected to rotating connecting shafts, and a set of rotating connecting shafts are respectively rotatably connected to both ends of the central bearing frame. The rotating connecting shafts are located at the center point of the end face of the central bearing frame.

[0007] Furthermore, the wind-resistant protection unit also includes: The fixing strip is fixedly connected to the mounting frame, and the rotating connecting shaft is rotatably connected to the fixing strip. The connection point between the rotating connecting shaft and the fixing strip is the center point of the fixing strip. The top and bottom flip plates are each fixedly connected to a rotating connecting rod at one end near the central support frame. The top and bottom flip plates are rotatably connected to the central support frame through a set of rotating connecting rods. Mounting plates are fixedly connected to both ends of the rotating connecting rods. One end of the first hydraulic push rod is rotatably connected to the mounting plate, and the other end is rotatably connected to the fixing strip.

[0008] Furthermore, the central support frame is provided with buffer pads on its edge.

[0009] Furthermore, the first hydraulic push rod connected to the top flip plate is rotatably connected to the end of the fixing bar near the buffer pad, and the first hydraulic push rod connected to the bottom flip plate is rotatably connected to the end of the fixing bar away from the buffer pad. A set of first hydraulic push rods connected to the top flip plate and a set of first hydraulic push rods connected to the bottom flip plate are symmetrically arranged.

[0010] Furthermore, the adaptive leveling unit also includes: The lower cup seat is coaxially fixedly connected to the fixed pile. The lower cup seat is coaxially provided with a limiting cone groove. The end of the floating leveling plate near the fixed pile is fixedly connected to a connecting column. The end of the connecting column away from the floating leveling plate is provided with a hemispherical head. The floating leveling plate and the connecting column are respectively provided with through holes. The hemispherical head is set inside the lower cup seat, and the connecting column is connected to the lower cup seat ball through the hemispherical head. Multiple second hydraulic push rods are provided between the fixed pile and the connecting column. One end of the second hydraulic push rod is rotatably connected to the fixed pile, and the other end is rotatably connected to the connecting column.

[0011] Furthermore, a central locking fastener is coaxially inserted into the through hole, and a conical head that matches the central locking fastener is provided at one end near the limiting conical groove. The central locking fastener is coaxially fixedly connected to a driven bevel gear, and a follower component is coaxially fixedly connected to the rotating connecting shaft.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention, through the cooperation of the first hydraulic push rod, the central bearing frame, the rotating connecting rod and the fixing strip, enables the top flip plate and the bottom flip plate at both ends of the central bearing frame to be opened or closed simultaneously from both sides of the central bearing frame, ensuring that the photovoltaic panel reduces the wind-exposed area of ​​the photovoltaic power generation device under severe weather conditions, and at the same time avoids damage to the photovoltaic panel under severe weather conditions such as rain, snow and hail.

[0014] 2. This invention uses the cooperation of the second hydraulic push rod, the central locking fastener, the third hydraulic push rod, and the lower bowl seat to adjust the rotation of the floating leveling plate relative to the lower bowl seat, thereby achieving active and precise leveling. This avoids the possibility of slight displacement or shaking of the fixed pile under long-term load and water flow scouring, which could cause the photovoltaic panel to tilt, reduce power generation efficiency, and damage the surrounding photovoltaic panels.

[0015] 3. The present invention uses the cooperation of the first hydraulic push rod, the rotating connecting rod and the follower component to enable the driving bevel gear and the driven bevel gear to mesh and transmit power. The conical head on the central locking fastener moves downward to lock the floating leveling plate and the fixed pile, and rigidly connects the entire upper frame and the fixed pile into one unit. By cooperating with the adaptive leveling part, the folded photovoltaic panel is locked in a state with the minimum wind-receiving area, reducing the damage to the photovoltaic panel caused by severe weather.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 8 This embodiment of the present invention provides a solar photovoltaic power generation device suitable for coastal mudflats, which includes an installation frame 1, a fixing pile 2, a wind-resistant protection part 3 and an adaptive leveling part 4. The installation frame 1 is provided with a central bearing frame 11, and a top flip plate 12 and a bottom flip plate 13 are rotatably connected to both ends of the central bearing frame 11, respectively. A buffer pad is provided on the edge of the central bearing frame 11. Photovoltaic panels 14 are provided on the central bearing frame 11, the top flip plate 12 and the bottom flip plate 13.

[0020] Both ends of the central load-bearing frame 11 are fixedly connected to rotating connecting shafts 111. A set of rotating connecting shafts 111 are rotatably connected to both ends of the mounting frame 1. The rotating connecting shafts 111 are located at the center point of the end face of the central load-bearing frame 11.

[0021] The central support frame 11 is equipped with a weather detector and a control board. The control board is electrically connected to the weather detector, the first hydraulic push rod 33, the second hydraulic push rod 43 and the third hydraulic push rod 52 respectively.

[0022] Usage process: First, drive the fixed pile 2 into the tidal flat foundation, install the bottom of the mounting frame 1 and the lower bowl seat 21 on the fixed pile 2, and install the central locking fastener 5. Weather data is detected by multiple different sensors of the meteorological detector and transmitted to the control board in real time. Finally, the control board controls the first hydraulic push rod 33 and the second hydraulic push rod 43 to perform the operation.

[0023] The weather detector here is a current technology, consisting of multiple different sensors installed on the frame of the central support frame 11. It does not affect the photovoltaic panel 14 from receiving sunlight. It only serves to detect meteorological data and will not be described in detail.

[0024] Please see Figures 1 to 4 The wind-resistant protection unit 3 is installed on the mounting frame 1 and the central load-bearing frame 11. The wind-resistant protection unit 3 includes multiple first hydraulic push rods 33 for preventing the photovoltaic panels 14 from being damaged in severe weather.

[0025] The wind-resistant protection unit 3 also includes: a fixing strip 32 fixedly connected to the mounting frame 1, a rotating connecting shaft 111 rotatably connected to the fixing strip 32, and the connection point between the rotating connecting shaft 111 and the fixing strip 32 is the center point of the fixing strip 32.

[0026] The top flip plate 12 and the bottom flip plate 13 are both fixedly connected to the central support frame 11 at one end. The top flip plate 12 and the bottom flip plate 13 are rotatably connected to the central support frame 11 through a set of rotating connecting rods 31. Both ends of the rotating connecting rods 31 are fixedly connected to mounting plates. One end of the first hydraulic push rod 33 is rotatably connected to the mounting plate, and the other end is rotatably connected to the fixing strip 32.

[0027] The fixing strip 32 is perpendicular to the central support frame 11, and the first hydraulic push rod 33 connected to the top flip plate 12 is rotatably connected to the end of the fixing strip 32 near the buffer pad strip, and the first hydraulic push rod 33 connected to the bottom flip plate 13 is rotatably connected to the end of the fixing strip 32 away from the buffer pad strip; a set of first hydraulic push rods 33 connected to the top flip plate 12 and a set of first hydraulic push rods 33 connected to the bottom flip plate 13 are symmetrically arranged.

[0028] Usage process: When the wind pressure sensor of the weather detector detects that the wind speed is lower than the set value or other sensors detect that the weather data is normal, one end of the first hydraulic push rod 33 is rotatably connected to the mounting plate and the other end is rotatably connected to the fixing strip 32, and the connection point between the rotating connecting shaft 111 and the fixing strip 32 is the center point of the fixing strip 32. At this time, the output ends of the two sets of first hydraulic push rods 33 simultaneously push the rotating connecting rods 31 at both ends of the central support frame 11, so that the top flip plate 12 and the bottom flip plate 13 at both ends of the central support frame 11 are opened from both sides of the central support frame 11. At this time, the photovoltaic panels 14 on the central support frame 11, the top flip plate 12 and the bottom flip plate 13 are exposed and enter the working state.

[0029] When the top flip plate 12 and bottom flip plate 13 at both ends of the central support frame 11 are in the maximum open state, the photovoltaic panels 14 on the central support frame 11, the top flip plate 12 and the bottom flip plate 13 are arranged in parallel, and the tilt angle between the central support frame 11 and the installation frame 1 is set to the optimal angle for receiving solar energy.

[0030] When the wind pressure exceeds the threshold or other sensors detect abnormal meteorological data, the output ends of the two sets of first hydraulic push rods 33 simultaneously pull the rotating connecting rods 31 at both ends of the central support frame 11, so that the top flip plate 12 and bottom flip plate 13 at both ends of the central support frame 11 are simultaneously retracted from both sides of the central support frame 11. At this time, the photovoltaic panels 14 on the central support frame 11 and the top flip plate 12 are covered. After the final retraction, the central support frame 11 is set parallel to the installation frame 1, reducing the wind-receiving area of ​​the photovoltaic power generation device and preventing the photovoltaic panels 14 from being damaged in severe weather such as rain, snow, and hail.

[0031] Please see Figures 5 to 7 The adaptive leveling unit 4 is disposed between the mounting frame 1 and the fixed pile 2. The adaptive leveling unit 4 is used to automatically adjust the floating leveling plate 41 that causes the photovoltaic panel 14 to tilt due to the shaking of the fixed pile 2.

[0032] The adaptive leveling unit 4 also includes a lower cup seat 21 that is coaxially fixedly connected to the fixed pile 2. The lower cup seat 21 is coaxially provided with a limiting cone groove 42. The floating leveling plate 41 is fixedly connected to a connecting column 411 at one end near the fixed pile 2. The connecting column 411 is provided with a hemispherical head at one end away from the floating leveling plate 41. Both the floating leveling plate 41 and the connecting column 411 are provided with corresponding through holes 4111.

[0033] The hemispherical head is set inside the lower bowl seat 21. The connecting column 411 is spherically connected to the lower bowl seat 21 through the hemispherical head. Multiple second hydraulic push rods 43 are provided between the fixed pile 2 and the connecting column 411. One end of the second hydraulic push rod 43 is rotatably connected to the fixed pile 2, and the other end is rotatably connected to the connecting column 411.

[0034] A central locking fastener 5 is coaxially inserted into the through hole 4111, and a conical head 51 adapted to the central locking fastener 5 is provided at one end near the limiting conical groove 42. The central locking fastener 5 is coaxially fixedly connected to a driven bevel gear 53, and a follower component 55 is coaxially fixedly connected to the rotating connecting shaft 111. The follower component 55 is rotatably connected to a driving bevel gear 54, which meshes with the driven bevel gear 53 for transmission. The outer wall of the central locking fastener 5 is provided with a thread 52, and the conical head 51 is provided with a thread groove that matches the thread 52.

[0035] Usage process: When the fixed pile 2 is slightly displaced, the floating leveling plate 41 contacts the lower bowl seat 21 through its lower spherical surface. The output end of multiple second hydraulic push rods 43 adjusts the rotation of the floating leveling plate 41 relative to the lower bowl seat 21, thereby achieving active and precise leveling. This avoids the photovoltaic panel 14 from tilting due to slight displacement or shaking of the fixed pile 2 under long-term load and water flow, which would reduce power generation efficiency and damage the surrounding photovoltaic panels 14.

[0036] When encountering severe weather, the photovoltaic panel 14 is retracted. During the process of the first hydraulic push rod 33 pulling the rotating connecting rod 31, the rotating connecting shaft 111 rotates relative to the mounting frame 1, thereby driving the follower component 55 to transmit power, which in turn causes the driving bevel gear 54 to mesh with the driven bevel gear 53. When the central locking fastener 5 rotates, since the conical head 51 is threadedly engaged with the central locking fastener 5, and the conical head 51 is provided with a protrusion, while the lower cup seat 21 is provided with a groove, the rotational freedom of the conical head 51 is restricted. Therefore, the conical head 51 on the central locking fastener 5 moves downward, locking the floating leveling plate 41 and the fixed pile 2.

[0037] Among them, the conical head 51 on the central locking fastener 5 is connected to the conical surface of the limiting conical groove 42 in the lower cup seat 21. Here, the follower component 55 can be a set of bevel gears meshing at ninety degrees and a rotating shaft that is coaxially fixedly connected to a set of bevel gears. At the same time, the metal-to-metal conical surface of the conical head 51 and the limiting conical groove 42 cooperate to directly transmit all horizontal forces and torsional moments to the fixed pile 2 in the form of compression and shear, and rigidly connect the entire upper frame with the fixed pile 2 as one unit. By cooperating with the adaptive leveling part 4, the folded photovoltaic panel 14 is locked in the state of minimizing the wind-receiving area, reducing the damage of severe weather to the photovoltaic panel 14.

[0038] As can be seen from the above, the working principle of this application is as follows: First, drive the fixed pile 2 into the tidal flat foundation. Then, install the floating leveling plate 41 at the bottom of the mounting frame 1 with the lower cup seat 21 on the fixed pile 2, and insert the central locking fastener 5. The central load-bearing frame 11 and the top flip plates 12 and bottom flip plates 13 at both ends have two modes: Normal leveling mode: When the wind pressure sensor of the meteorological detector detects that the wind speed is lower than the set value or other sensors detect that the meteorological data is normal, one end of the first hydraulic push rod 33 is rotatably connected to the mounting plate and the other end is rotatably connected to the fixing strip 32, and the connection point between the rotating connecting shaft 111 and the fixing strip 32 is the center point of the fixing strip 32. At this time, the output ends of the two sets of first hydraulic push rods 33 simultaneously push the rotating connecting rods 31 at both ends of the central support frame 11, so that the top flip plate 12 and the bottom flip plate 13 at both ends of the central support frame 11 are opened from both sides of the central support frame 11. At this time, the photovoltaic panels 14 on the central support frame 11, the top flip plate 12 and the bottom flip plate 13 are exposed and enter the working state.

[0039] When the top flip plate 12 and bottom flip plate 13 at both ends of the central support frame 11 are in the maximum open state, the photovoltaic panels 14 on the central support frame 11, the top flip plate 12 and the bottom flip plate 13 are arranged in parallel, and the tilt angle between the central support frame 11 and the installation frame 1 is set to the optimal angle for receiving solar energy.

[0040] Strong wind locking mode: When the wind pressure exceeds the threshold or other sensors detect abnormal meteorological data, the output ends of the two sets of first hydraulic push rods 33 simultaneously pull the rotating connecting rods 31 at both ends of the central support frame 11, so that the top flip plate 12 and bottom flip plate 13 at both ends of the central support frame 11 are simultaneously retracted from both sides of the central support frame 11. At this time, the photovoltaic panels 14 on the central support frame 11 and the top flip plate 12 are covered, and the central support frame 11 after the final retraction is completed is set parallel to the installation frame 1.

[0041] Meanwhile, as the first hydraulic push rod 33 pulls the rotating connecting rod 31, the rotating connecting shaft 111 rotates relative to the mounting frame 1, thereby driving the follower component 55 to transmit power, which in turn causes the driving bevel gear 54 to mesh with the driven bevel gear 53. The conical head 51 on the central locking fastener 5 moves downward to lock the floating leveling plate 41 and the fixed pile 2. The conical head 51 on the central locking fastener 5 is connected to the conical surface of the limiting conical groove 42 in the lower bowl seat 21. At this time, the metal-to-metal conical surface of the conical head 51 and the limiting conical groove 42 cooperate to directly transmit all horizontal forces and torsional moments to the fixed pile 2 in the form of compression and shear, and rigidly connect the entire upper frame with the fixed pile 2 as one unit. By cooperating with the adaptive leveling part 4, the folded photovoltaic panel 14 is locked in the state of minimum wind-receiving area.

[0042] When the fixed pile 2 undergoes slight displacement, the floating leveling plate 41 contacts the lower cup seat 21 through its lower spherical surface. The output ends of multiple second hydraulic push rods 43 adjust the rotation of the floating leveling plate 41 relative to the lower cup seat 21, thereby achieving active and precise leveling.

[0043] If the wind speed continues to rise after the control board receives the warning but does not reach the emergency threshold, it first activates the adaptive leveling unit 4 to ensure that the central load-bearing frame 11 is in a horizontal or preset safety reference posture. Then, it controls the first hydraulic push rod 33 to quickly pull the flip plate to close. Since the central load-bearing frame 11 has been pre-leveled and is in a stable reference state, the folding process is smoother and faster, reducing the risk of asynchronous or stuck folding due to the frame's own tilt.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
