Description

Technical Field

[0001] This utility model relates to the field of water surface photovoltaic technology, specifically a water surface photovoltaic mooring system. Background Technology

[0002] A floating photovoltaic (PV) mooring system is an anchoring and positioning device specifically designed for floating PV power plants. Through the coordinated action of key components such as cables, anchor chains, and anchoring foundations, it dynamically stabilizes the PV array in the aquatic environment. This system must balance natural loads such as wind, waves, and currents with complex environmental constraints. It employs elastic connections to allow for moderate displacement of the floating bodies to reduce impact loads, while also possessing excellent corrosion resistance and tensile strength to ensure that the PV panels maintain structural integrity and high-efficiency power generation even under fluctuating water levels. Due to its strong adaptability, it is widely used in various aquatic conditions such as reservoirs and lakes, serving as a crucial support system for ensuring the safe and stable operation of floating PV power plants.

[0003] CN201920494880.0 discloses a surface photovoltaic support system, including a floating body and component support. The overall structure of the floating body adopts two parallel supporting floating bodies and a connecting floating body, with the supporting floating bodies maintaining a certain distance and connected by the connecting floating body. The supporting floating bodies are equipped with maintenance channels, and the floating bodies are connected to form a photovoltaic array via connecting lugs. However, the cables in the above system rely solely on their own elasticity for deployment and retraction, and cannot be actively adjusted according to the rise and fall of the water level. This makes it difficult to adequately match the pulling force required for different water level rises, thus affecting the usability of the mooring system.

[0004] Therefore, it is of great significance to design a surface photovoltaic mooring system that can automatically match the pulling force required for different water level rises. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings in the above-mentioned background technology and provide a water surface photovoltaic mooring system. This system should have the function of automatically adjusting the cable tension for different water level rises and the advantage of automatically lubricating the cable to increase its service life.

[0006] The technical solution of this utility model is: A surface photovoltaic mooring system includes a float, a photovoltaic panel disposed on the upper side of the float, and cables disposed at the four corners of the float to connect to an anchoring foundation; characterized in that: the float is provided with a deployment and retraction structure, a water level sensor, and an electrical control center that electrically connects the deployment and retraction structure and the water level sensor; The cable retraction and deployment structure includes two cable retraction and deployment assemblies located at both ends of the side of the float plate and a lubrication assembly located above the cable retraction and deployment assemblies.

[0007] The cable winding and unwinding assembly includes a support plate mounted on the upper side of the float, a double-ended motor mounted on the support plate, two rotating rods coaxially connected to the two output shafts of the double-ended motor, and two fixed plates movably connected to the suspended ends of the two rotating rods. The cable is wound around the surface of the rotating rods.

[0008] The fixed plate is provided with a bearing for movably connecting with the rotating rod, and a triangular block for reinforcing the floating plate is provided on the outer side.

[0009] The lubrication assembly includes a flat plate disposed on the upper side of the float and located below the rotating rod, a reciprocating plate horizontally movable and positioned on the flat plate and having threaded holes, a reciprocating threaded sleeve coaxially fixed to the rotating rod and engaging with the threaded holes, a lubricating oil box disposed on the top of the reciprocating plate, a wiping plate disposed on the side of the reciprocating plate and having brushes arranged at its lower end, solenoid valves disposed on both sides of the lubricating oil box and communicating with the inner cavity of the lubricating oil box, an oil inlet pipe interface disposed on the top of the lubricating oil box, and a corrugated hose whose two ends are respectively connected to the solenoid valves and the wiping plate to deliver lubricating oil to the brushes.

[0010] The top of the plate is provided with a moving groove that slides with the lower end of the reciprocating plate and a limiting frame for limiting the sliding of the reciprocating plate.

[0011] The direction of movement of the reciprocating plate is parallel to the axial direction of the double-ended motor.

[0012] The electrical control center is electrically connected to the solenoid valve and the double-ended motor.

[0013] The beneficial effects of this utility model are: 1. This system monitors water level information in real time via a water level sensor and transmits it to the electrical control center, which then drives the deployment and retraction mechanism to adjust the cable tension. Compared to traditional anchoring devices that rely on the elasticity of the cable itself to adjust the cable tension, this system has the function of automatically adjusting the cable tension according to different water level rises, greatly improving the quality of the mooring system.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, a surface photovoltaic mooring system includes a float 1, photovoltaic panels 2, cables 3, a launch and retrieve mechanism, water level sensors 5, and an electrical control center. The photovoltaic panels are installed on the upper side of the float for photovoltaic power generation. The launch and retrieve mechanism is installed on both sides of the upper side of the float. One end of the cables is connected to the launch and retrieve mechanism, and the other end is connected to an anchoring foundation on the bottom of the nearby water area. The water level sensors are installed on both sides of the float to monitor the water level in real time and convert it into electrical signals that are transmitted to the electrical control center. The electrical control center is electrically connected to the launch and retrieve mechanism and the water level sensors.

[0022] like Figure 3 and Figure 4 As shown, the deployment and retrieval structure includes two cable deployment and retrieval assemblies 4 and two lubrication assemblies 6. The two cable deployment and retrieval assemblies are located at both ends on the upper side of the float, and the cables are connected to these assemblies. The lubrication assemblies are located above the cable deployment and retrieval assemblies to lubricate the cables and reduce the risk of cable aging and breakage.

[0023] like Figure 3 and Figure 4As shown, the cable winding and unwinding assembly includes a support plate 4.1, a double-ended motor 4.2, a fixing plate 4.3, a rotating rod 4.4, and a triangular block 4.5. The support plate is positioned above the float, and the double-ended motor is mounted on the upper side of the support plate. A fixing plate is vertically mounted on both sides of the axial direction of the double-ended motor, and the output shafts of the two motors are coaxially connected to one end of the rotating rod via couplings. The other end of the rotating rod is mounted on the fixing plate via bearings (as shown in the figure, the rotation axes of the two double-ended motors in the two cable winding and unwinding assemblies are parallel to each other). The lower end of the fixing plate is fixed to the float, and the fixing plate is equipped with the bearings, the axis of which coincides with the rotation axis of the double-ended motors. The fixing plate is further reinforced by the triangular block connected to the float. The cable is wound around the rotating rod, and the double-ended motor drives the rotating rod to rotate, thereby changing the number of cable turns on the rotating rod and adjusting the working length and tensile force of the cable.

[0024] like Figure 3 and Figure 4 As shown, the lubrication assembly includes a flat plate 6.1, a reciprocating plate 6.2, a reciprocating threaded sleeve 6.3, a lubricating oil box 6.4, a friction plate 6.5, a solenoid valve 6.6, an oil inlet pipe interface 6.7, and a corrugated hose 6.8. The flat plate is positioned above the float plate and below the rotating rod. The reciprocating plate is horizontally movable and has threaded holes on its upper side. Each rotating rod is coaxially fitted with a reciprocating threaded sleeve, the threads on the reciprocating threaded sleeve matching the threaded holes. The reciprocating threaded sleeve passes through the threaded holes and is threadedly connected to the reciprocating plate. The lubricating oil box is located above the double-ended motor, with its lower side fixed to the top of the reciprocating plate at both ends along its length. The upper end of the lubricating oil box has an oil inlet pipe interface, allowing lubricating oil to be replenished to the inner cavity of the box via the connecting oil inlet pipe. A solenoid valve is located at each end of the lubricating oil box, and the solenoid valves are electrically connected to the electrical control center. The wiping plate is located on the side of the reciprocating plate, above the cable on the rotating rod. The upper end of the wiping plate is connected to the outlet of the solenoid valve via a corrugated hose, and the lower end is equipped with a brush that contacts the cable. When the rotating rod rotates, the reciprocating plate is driven to move horizontally through the reciprocating threaded sleeve. The wiping plate on the reciprocating plate wipes the cable on the rotating rod and evenly spreads the lubricating oil output through the solenoid valve onto the cable.

[0025] like Figure 3 As shown, the flat plate has a moving groove 6.1.1, and the protruding strips around the moving groove form a limiting frame 6.1.2. The moving groove is located on the upper side of the flat plate, and the lower end of the reciprocating plate is horizontally movable and positioned within the moving groove, with the direction of movement parallel to the direction of the axis of the double-ended motor. The limiting frame can limit the movement of the reciprocating plate.

[0026] The working principle and usage process of this utility model are as follows: First, the water level sensor 5 is responsible for monitoring the rise and fall of the surrounding water level. Its working mechanism involves measuring the pressure exerted by the liquid on itself, converting this pressure value into an electrical signal, and transmitting it to the electronic control center (existing technology). After processing, the electronic control center can obtain the current liquid level height.

[0027] If the measured water level rise exceeds the set range, the electrical control center drives the dual-end motor 4.2 to operate, which in turn drives the rotating rod 4.4 to rotate. The rotating rod 4.4 can adjust the cable tension for different water level rises by retracting and extending the cable 3, automatically adjusting the draft of the photovoltaic mooring system. Since the cable 3 needs to be frequently retracted and extended to follow water level changes, its retraction and extension parts are prone to wear. Therefore, the electrical control center controls the opening of the solenoid valve 6.6 of the lubricating oil box 6.4, and the lubricating oil is discharged into the brush of the wiping plate 6.5 through the corrugated hose 6.8. The wiping plate 6.5 then wipes the cable 3 with the brush to maintain its good lubrication, thereby achieving the purpose of convenient maintenance of the cable 3.

[0028] In summary, this surface photovoltaic mooring system innovates the traditional method of relying on its own elasticity for tensioning and releasing. By sensing the water level position through the water level sensor 5, and then using the rotating rod 4.4 to control the tension of the cable 3, it can automatically adjust the tension of the cable 3 according to different water level rises, effectively improving the quality of use of the mooring system.

[0029] The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.
