Description

Technical Field

[0001] The present invention relates to the technical field of water surface photovoltaics, and in particular to a water surface photovoltaic installation system and an application method thereof. Background Art

[0002] In the prior art, the commonly used water surface photovoltaic installation system is a device that installs a floating body on the water surface and then installs photovoltaics on the surface of the floating body to achieve photovoltaic installation and power generation. However, when the water surface photovoltaic installation system is in unstable waters such as the sea surface or unstable weather conditions outdoors, after encountering wind and waves or rain, these liquids are easy to accumulate on the surface of the floating body and are difficult to be discharged from the photovoltaic installation area, which will damage the photovoltaics and further affect the working efficiency of the photovoltaics. Summary of the invention

[0003] In view of this, the present invention proposes a water surface photovoltaic installation system and an application method thereof, and the specific scheme is as follows:

[0004] In the first aspect, a water surface photovoltaic installation system is proposed, including an airbag body and a supporting structure;

[0005] The airbag body includes a first surface and a second surface that are correspondingly arranged, the first surface is used for installing photovoltaics, and the second surface is used for contacting the external water surface; the support structure is arranged at the edge of the airbag body, and is used to support the airbag body;

[0006] The airbag body includes at least one cabin; the cabin is provided with at least one opening, and the opening is used to switch the airbag body between the expanded and contracted states;

[0007] A liquid discharge surface for discharging liquid to the outside is formed on the first surface of the airbag body in the deployed state.

[0008] It should be noted that the present application does not specifically limit the structural shape of the liquid discharge surface. As long as the function of discharging the liquid from the first surface to the outside can be achieved, there can be a variety of structural options. The liquid discharge surface includes a plane or curved surface with a highest point and a lowest point, so that the liquid falling on the first surface can flow along the high point of the curved surface to the low point until it is discharged to the outside. In a specific embodiment, the liquid discharge surface includes a slope surface with a slope, so that the liquid falling on the first surface can flow and be discharged along the slope from high to low.

[0009] In some specific embodiments, the thickness of the airbag body in the deployed state decreases from the middle of the airbag body to the edge of the airbag body close to the outside. In practical applications, by decreasing the thickness of the airbag body in the deployed state from the middle to the edge close to the outside, the first surface of the airbag body forms a convex arc surface on the plane where the airbag body is located, so that the liquid falling on the first surface can be dispersed from the middle of the airbag body, that is, the middle of the first surface, along the arc surface to the surroundings due to gravity, and the liquid will not gather on the first surface.

[0010] In some specific embodiments, the interior of the airbag includes a plurality of regions; at least one cabin is disposed in each region; and a valve is disposed at a corresponding opening position on the cabin.

[0011] In practical applications, the airbag body needs to be stable above the water surface. Therefore, liquid can be injected into the cabin near the second surface of the airbag body to increase the weight of the airbag body and partially or completely sink the second surface of the airbag body into the water. In a specific embodiment, the airbag body can include a first area near the first surface of the airbag body and a second area near the second surface of the airbag body. The first area and the second area can be isolated from each other, thereby realizing the upper and lower structure cabins in the airbag body. At least one cabin is respectively provided in the first area and the second area.

[0012] During use, the user can inject liquid into part or all of the cabin located in the second area, and inflate part or all of the cabin located in the first area, so that the first area in the airbag body is mainly gas and the second area is mainly liquid. This can make the position corresponding to the second area in the airbag body submerged in water, ensuring the stability of the airbag body on the water surface.

[0013] By setting up multiple capsules, users can inflate or deflate multiple capsules, inject or release liquid into or out of multiple capsules at the same time during use, which can effectively shorten the time required to deploy and collapse the airbag body. At the same time, due to the multiple capsules, if one capsule suddenly breaks and stops working, the broken capsule will not affect the normal operation of other capsules, further extending the overall service life of the airbag body and expanding the use scenarios of the airbag body.

[0014] In some specific embodiments, it also includes a photovoltaic mounting member and a first fixing member; a connection auxiliary member is provided on the first surface of the airbag body; the first fixing member passes through the photovoltaic mounting member and the connection auxiliary member to fix the photovoltaic mounting member on the first surface, wherein the photovoltaic mounting member is integrally formed with the photovoltaic, or the photovoltaic mounting member is used for a detachable connection with the photovoltaic.

[0015] In practical applications, the photovoltaic to be installed is a photovoltaic panel, and the photovoltaic mounting piece can be connected to the edge of the photovoltaic panel to fix the photovoltaic panel on the first surface. The connection auxiliary piece can be a connection film material, one side of the connection film material can be connected to the first surface by welding, and the other side is a free end for contacting the photovoltaic mounting piece, and the first fixing piece can be a fixing bolt. In a specific embodiment, a plurality of first mounting holes are provided on the connection auxiliary piece, and a second mounting hole corresponding to the first mounting hole is provided on the photovoltaic mounting piece, and the first fixing piece passes through the first mounting hole and the second mounting hole in sequence, or passes through the second mounting hole and the first mounting hole in sequence to fix the connection auxiliary piece and the photovoltaic mounting piece.

[0016] In a specific embodiment, it also includes an elastic member that can be sleeved with the first fixing member, and the elastic member is sleeved on one end of the first fixing member close to the first surface, and is used to form an elastic deformation space between the connection position of the first fixing member and the auxiliary connecting member, so that when the auxiliary connecting member is subjected to external force, the elastic member can cooperate with the auxiliary connecting member to deform under the action of the external force, offset the external force on the photovoltaic and / or the connection position of the first fixing member and the auxiliary connecting member, and protect the photovoltaic and the connection position of the first fixing member and the auxiliary connecting member from damage. In practical applications, the elastic member can be a spring structure.

[0017] In a specific embodiment, a protective layer is further provided on the first surface at a position corresponding to the installation position of the first fixing member. In practical applications, when the first fixing member is a metal member such as a fixing bolt, if it contacts the first surface for a long time, friction may be generated to wear the first surface. Therefore, providing a protective layer at the corresponding position can prevent the first surface from being scratched or worn, reduce the number of maintenance times for the first surface, and extend the overall service life of the airbag body. In practical applications, the protective layer can include a protective film material with high strength.

[0018] In some specific embodiments, a limiting member is provided on part or all of the edges of the photovoltaic mount and / or the auxiliary connection member, and the limiting member is used to strengthen the connection strength of at least one of the photovoltaic mount and the auxiliary connection member and the first fixing member. In a specific embodiment, the limiting member protrudes relative to the photovoltaic mount and / or the auxiliary connection member, and after the first fixing member passes through the photovoltaic mount and the auxiliary connection member, the side exposed to the photovoltaic mount contacts and engages with the limiting member on the edge of the photovoltaic mount, and the side exposed to the auxiliary connection member contacts and engages with the limiting member on the edge of the auxiliary connection member. In practical applications, the limiting member can be a rope-buried edge. The rope-buried edge is provided on the edges of the photovoltaic mount and the auxiliary connection member, which can limit the first fixing member while strengthening the strength of the edges of the photovoltaic mount and the auxiliary connection member.

[0019] In some specific embodiments, the support structure includes a support frame and a support tube; a through hole is provided on the support frame, and one or more support tubes pass through the through hole to be fixed on the support frame; a first connecting part extends from the edge of the airbag body; one or more of the support tubes are covered with a second connecting part, and the second connecting part is fixedly connected to the free end of the first connecting part.

[0020] In some specific embodiments, a cable net system and a mounting rail are further included; the cable net system is disposed on the first surface; the mounting rail is used for detachably connecting with one or more photovoltaic blocks;

[0021] A transfer structure is provided on the cable net system, and the mounting rail is fixedly connected to the cable net system through the transfer structure, so that the photovoltaic can be detachably installed on the cable net system.

[0022] In practical applications, the cable net system includes multiple cable net structures, and the two ends of each cable net structure are connected to different areas on the supporting structure, so that the cable net structure can span the area corresponding to the first surface. In the cable net system, each cable net structure can be distributed in a variety of ways, such as multiple cable net structures are arranged parallel to each other on the first surface, or multiple cable net structures are arranged staggered on the first surface, or multiple cable net structures are evenly arranged vertically and horizontally on the first surface.

[0023] After completing the installation of the cable net system on the first surface, the user can set a transfer structure at a corresponding position on the cable net system according to the position distribution of the photovoltaics to be installed, and then connect the mounting rail to the transfer structure, so that the mounting rail is fixedly connected to the cable net system, and further slidably install the photovoltaics on the mounting rail. In some specific embodiments, a spacing structure is also provided between adjacent photovoltaics on the mounting rail; the spacing structure is used to limit the position of the photovoltaics connected to the mounting rail. In practical applications, by using a spacing structure on the cable net system, the movement of adjacent photovoltaics on the mounting rail can be limited.

[0024] In some specific embodiments, the control terminal and a cabin detection device connected to the cabin are also included; the cabin detection device is used to detect the filling status of gas and / or liquid inside the cabin to determine the integrity of the cabin;

[0025] The control terminal is communicatively connected to the cabin detection device and the opening, and is used to control the opening or closing of the opening according to the detection result of the cabin detection device.

[0026] In the second aspect, an application method of a water surface photovoltaic installation system is proposed, which is applicable to any water surface photovoltaic installation system in the aforementioned technical solution, and the specific method includes:

[0027] Calculate a target value of the sinking depth of the airbag body and a target value of the amount of gas and / or liquid inside the cabin according to environmental parameters of a target installation area of ​​the water surface photovoltaic installation system;

[0028] Control the switches of each cabin to open, so that external gas and / or liquid enter the cabin until the amount of gas and / or liquid inside the cabin reaches the target value;

[0052] Example 1

[0053] This embodiment discloses a water surface photovoltaic installation system, and the specific scheme is as follows, including:

[0054] A water surface photovoltaic installation system includes an airbag body 1 and a support structure 42. The airbag body 1 includes a first surface 11 and a second surface 12 that are correspondingly arranged, the first surface 11 is used to install the photovoltaic 7, and the second surface 12 is used to contact the external water surface; the support structure 42 is arranged at the edge of the airbag body 1, and is used to support the airbag body 1;

[0055] The airbag body 1 includes at least one cabin 13; the cabin 13 is provided with at least one opening 131, and the opening 131 is used to switch the airbag body 1 between the expanded and contracted states; a drainage surface 111 for discharging liquid to the outside is formed on the first surface 11 of the airbag body 1 in the expanded state.

[0056] It should be noted that the present application does not specifically limit the structural shape of the drainage surface 111. As long as the function of discharging the liquid from the first surface 11 to the outside can be achieved, there can be a variety of structural options. The drainage surface 111 can be a sloped surface, so that the liquid falling on the first surface 11 can flow along the slope direction and be discharged; the drainage surface 111 can also be a curved surface with the highest point and the lowest point, so that the liquid falling on the first surface 11 can flow from the high point to the low point along the curved surface until it is discharged to the outside.

[0057] In some specific embodiments, the thickness of the airbag body 1 in the deployed state decreases from the middle of the airbag body 1 to the edge of the airbag body 1 close to the outside. In practical applications, by making the thickness of the airbag body 1 in the deployed state decrease from the middle to the edge close to the outside, the first surface 11 of the airbag body 1 forms a convex arc surface on the plane where the airbag body 1 is located, such as Figure 3 As shown, this allows the liquid that falls on the first surface 11 to spread out from the middle of the airbag body 1 , that is, the middle of the first surface 11 , along the arc surface to the surrounding areas due to gravity, and the liquid will not gather on the first surface 11 .

[0058] In some specific embodiments, the interior of the airbag includes a plurality of regions; at least one cabin 13 is disposed in each region; and a valve is disposed on the cabin 13 at a position corresponding to the opening 131 .

[0059] In practical applications, the airbag body 1 needs to be stable above the water surface, so liquid can be injected into the cabin 13 in the second area close to the second surface 12 of the airbag body 1 to increase the weight of the airbag body 1 and sink part or all of the second surface 12 of the airbag body 1 into the water. In a specific embodiment, the airbag body 1 includes a first area close to the first surface 11 of the airbag body 1 and a second area close to the second surface 12 of the airbag body 1. The first area and the second area can be isolated from each other, thereby realizing the upper and lower structure compartments in the airbag body 1. At least one cabin 13 is respectively provided in the first area and the second area.

[0060] During use, the user can inject liquid into part or all of the cabin 13 located in the second area, and inflate part or all of the cabin 13 located in the first area, so that the first area in the airbag body 1 is mainly gas and the second area is mainly liquid. This can make the position corresponding to the second area in the airbag body 1 submerged in water, ensuring the stability of the airbag body 1 on the water surface.

[0061] like Figure 2 As shown, by providing multiple capsules 13, the user can simultaneously inflate or deflate multiple capsules 13, inject liquid into or release liquid during use, which can effectively shorten the time required to deploy and collapse the airbag body 1. At the same time, due to the multiple capsules 13, if a capsule 13 suddenly breaks and stops working, the broken capsule 13 will not affect the normal operation of other capsules 13, further extending the overall service life of the airbag body 1 and expanding the use scenarios of the airbag body 1.

[0062] It should be noted that the present application does not specifically limit the size of each area and the size of each cabin 13. The user can set the volume of each cabin 13 to be the same or different according to actual needs, and can also set the size of each area to be the same or different.

[0063] In some specific embodiments, a photovoltaic mounting component 31 and a first fixing component 32 are also included; a connection auxiliary component 33 is provided on the first surface 11 of the airbag body 1; the first fixing component 32 passes through the photovoltaic mounting component 31 and the connection auxiliary component 33 to fix the photovoltaic mounting component 31 on the first surface 11, the photovoltaic mounting component 31 is integrally formed with the photovoltaic 7, or the photovoltaic mounting component 31 is used for detachable connection with the photovoltaic 7.

[0064] In practical applications, the photovoltaic device 7 to be installed is a photovoltaic panel, and the photovoltaic mounting member 31 can be connected to the edge of the photovoltaic panel to fix the photovoltaic panel on the first surface 11. The connection auxiliary member 33 can be a connection film material, one side of the connection film material can be connected to the first surface 11 by heat sealing, and the other side is a free end for contacting the photovoltaic mounting member 31, and the first fixing member 32 can include a fixing bolt. The heat sealing connection range between the connection film material and the first surface can be as follows: Figure 4 and Figure 5 As shown in area A. In a specific embodiment, a plurality of first mounting holes are provided on the connection auxiliary member 33, and a second mounting hole corresponding to the first mounting hole is provided on the photovoltaic mounting member 31, and the first fixing member 32 is fixedly connected to the connection auxiliary member 33 and the photovoltaic mounting member 31 by sequentially passing through the first mounting hole and the second mounting hole, or sequentially passing through the second mounting hole and the first mounting hole.

[0065] In a specific embodiment, it also includes an elastic member 35 that can be sleeved with the first fixing member 32. The elastic member 35 is sleeved on one end of the first fixing member 32 close to the first surface 11, and is used to form an elastic deformation space between the connection position of the first fixing member 32 and the auxiliary connecting member. When the auxiliary connecting member is subjected to external force, the elastic member 35 can cooperate with the auxiliary connecting member to deform under the action of the external force, offset the external force on the photovoltaic 7 and / or the connection position of the first fixing member 32 and the auxiliary connecting member, and protect the photovoltaic 7 and the connection position of the first fixing member 32 and the auxiliary connecting member from damage.

[0066] In a specific embodiment, a protective layer 36 is further provided on the first surface 11 at a position corresponding to the installation position of the first fixing member 32. Figure 4 and Figure 5 In practical applications, when the first fixing member 32 is a metal member such as a fixing bolt, if it contacts the first surface 11 for a long time, friction may be generated to wear the first surface 11. Therefore, a protective layer 36 is provided at the corresponding position to prevent the first surface 11 from being scratched or worn, thereby reducing the number of maintenance times for the first surface 11 and extending the overall service life of the airbag body 1.

[0067] In some specific embodiments, a limiting member 34 is provided on part or all of the edges of the photovoltaic mounting member 31 and / or the connection auxiliary member 33, and the limiting member 34 is used to strengthen the connection strength between at least one of the photovoltaic mounting member 31 and the connection auxiliary member 33 and the first fixing member 32. In a specific embodiment, the limiting member 34 is raised relative to the photovoltaic mounting member 31 and / or the connection auxiliary member 33. After the first fixing member 32 passes through the photovoltaic mounting member 31 and the connection auxiliary member 33, the side exposed to the photovoltaic mounting member 31 contacts and engages with the limiting member 34 on the edge of the photovoltaic mounting member 31, and the side exposed to the connection auxiliary member 33 contacts and engages with the limiting member 34 on the edge of the connection auxiliary member 33. In practical applications, the limiting member 34 can be a rope-buried edge. The rope-buried edge is provided on the edges of the photovoltaic mounting member 31 and the connection auxiliary member 33, which can limit the first fixing member 32 and strengthen the strength of the edges of the photovoltaic mounting member 31 and the connection auxiliary member 33.

[0068] In some specific embodiments, the support structure 42 includes a support frame 21 and a support tube 22; the support frame 21 is provided with a through hole, and one or more support tubes 22 pass through the through hole to be fixed on the support frame 21; a first connecting portion 41 extends from the edge of the airbag body 1; one or more support tubes 22 are covered with a second connecting portion 42, and the second connecting portion 42 is fixedly connected to the free end of the first connecting portion 41. The specific connection is as follows Figure 6 , Figure 7 and Figure 8 shown.

[0069] In a specific embodiment, the first connection part 41 extending from the airbag body 1 can be a traction film material, and the second connection part 42 wrapped on the support tube 22 can also be a traction film material. The traction film material of the first connection part 41 wraps the traction film material of the second connection part 42 while wrapping the support tube 22, and fixedly connects them. In this way, the second connection part 42 can wrap the first connection part 41 and the support tube 22 at the same time, and the three can be fixedly connected, and the airbag body 1 and the support structure 42 can be further tightly connected.

[0070] In practical applications, the first connection part 41 and the second connection part 42 can be connected by a plate 44 and a second fixing member 43, such as overlapping the first connection part 41 and the second connection part 42, and then covering the two side surfaces of the overlap of the first connection part 41 and the second connection part 42 respectively, and the second fixing member 43 passes through the plate 44 on one side surface close to the overlap, the first connection part 41, the second connection part 42 and the plate 44 on the other side surface of the overlap in sequence, so as to realize the fixed connection of the first connection part 41 and the second connection part 42 through the plate 44 and the second fixing member 43. Among them, the plate 44 includes a metal plate and the second fixing member 43 includes a bolt. The present application does not specifically limit the method of fixed connection between the first connection part 41 and the second connection part 42. As long as the fixed connection between the two can be achieved, other methods are also possible, such as welding, or using a clamp, etc.

[0071] In practical applications, the edge of the first connection part 41 and / or the second connection part 42 may also be provided with a limiting member 34, and the limiting member 34 may be a rope-embedded edge. By providing the limiting member 34, when the second fixing member 43 passes through the first connection part 41 and the second connection part 42 respectively, the limiting member 34 may be engaged with the limiting member 34, and the limiting member 34 may limit and adjust the position of the plate member 44 and the second fixing member 43, and may also further strengthen the strength of the edge of the first connection part 41 and the second connection part 42. The specific structure of the rope-embedded edge may be as follows: Figure 7 and Fig.10 shown.

[0072] In practical applications, the support tube 22 may be an inflatable tube with an air port, through which the user may adjust the air pressure in the inflatable tube to further adjust the overall support force and overall buoyancy that the support frame 21 can provide to the airbag body 1.

[0073] In some specific embodiments, it also includes a cable net system 5 and a mounting rail 52; the cable net system 5 is arranged on the first surface 11; the mounting rail 52 is used for detachable connection with one or more photovoltaic blocks 7; a transfer structure 51 is provided on the cable net system 5, and the mounting rail 52 is fixedly connected to the cable net system 5 through the transfer structure 51, so that the photovoltaic 7 can be detachably installed on the cable net system 5.

[0074] In practical applications, such as Fig. 9 As shown, the cable net system 5 includes a plurality of cable net structures, and the two ends of each cable net structure are respectively connected to different areas on the support structure 42, so that the cable net structure can span the area corresponding to the first surface 11. In the cable net system 5, each cable net structure can be distributed in a variety of ways, such as multiple cable net structures are arranged on the first surface 11 in parallel, or multiple cable net structures are arranged on the first surface 11 in an alternating manner, or multiple cable net structures are evenly arranged on the first surface 11 in a longitudinal and transverse manner.

[0075] After completing the installation of the cable net system 5 on the first surface 11, the user can set the adapter structure 51 at the corresponding position on the cable net system 5 according to the position distribution of the photovoltaic 7 to be installed, and then connect the installation rail 52 with the adapter structure 51, so that the installation rail 52 can be slidably connected to the cable net system 5, and further install the photovoltaic 7 on the installation rail 52 slidably, as shown in FIG. Fig.11 shown.

[0076] By setting the cable net system 5, firstly, the connection between the support structure 42 and the airbag body 1 can be strengthened. Secondly, since the first surface 11 is a liquid discharge surface 111, in some specific cases, the first surface 11 may have an arc or a slope. At this time, by setting the cable net system 5 and further installing the photovoltaic 7 on the cable net system 5 through the transfer structure 51 and the mounting guide rail 52, the influence of the slope or arc of the first surface 11 on the photovoltaic 7 can be reduced. In actual application, the cable net structure in the cable net system 5 can be set in close contact with the first surface 11, or can be set at a partial distance from the first surface 11.

[0077] When most of the cable net system 5 is arranged in contact with the first surface 11, the first surface 11 can provide partial support force for the photovoltaic 7 to reduce the supporting pressure of the cable net system 5 on the photovoltaic 7; when most of the cable net system 5 is not arranged in contact with the first surface 11, the retention of liquid falling on the photovoltaic 7 and the cable net system 5 can be reduced, so as to better keep the surface of the cable net system 5 and the photovoltaic 7 dry.

[0078] In some specific embodiments, a spacing structure 53 is further provided between adjacent transfer structures 51 on the cable net system 5 and / or between adjacent photovoltaics 7 on the mounting rail 52; the spacing structure 53 is used to prevent the transfer structure 51 from driving the mounting rail 52 to move on the cable net system 5; and / or the spacing structure 53 is used to limit the movement of adjacent photovoltaics 7 on the mounting rail 52.

[0079] In practical applications, by providing a spacing structure 53 in the mounting rail 5, the movement of adjacent photovoltaics 7 on the mounting rail 5 can be limited. Therefore, by providing the spacing structure 53, the movement of the photovoltaics 7 relative to the first surface 11 can be effectively limited, so that the photovoltaics 7 on the first surface 11 are installed more stably.

[0080] In some specific embodiments, the control terminal 61 and a cabin detection device 62 connected to the cabin 13 are further included; the cabin detection device 62 is used to detect the filling condition of the gas and / or liquid inside the cabin 13 to determine the integrity of the cabin 13;

[0081] The control terminal 61 is connected to the cabin detection device 62 and the opening 131 for controlling the opening or closing of the opening 131 according to the detection result of the cabin detection device 62. Fig.13 shown.

[0082] This embodiment proposes a water surface photovoltaic installation system, which includes at least one cabin in the airbag body by setting an airbag body and a supporting structure; the cabin body is provided with at least one opening, and the opening is used to switch the airbag body between the expanded and contracted states; a liquid discharge surface for discharging liquid to the outside is formed on the first surface of the airbag body in the expanded state. The liquid falling on the first surface of the airbag body can be quickly discharged, and the photovoltaic will not be troubled by the liquid immersion. At the same time, there is no need to use additional equipment such as a water pump to assist in liquid discharge, which can effectively reduce the relevant manpower and material resources.

[0083] Example 2

[0084] This embodiment discloses an application method of a water surface photovoltaic installation system, which is applicable to any water surface photovoltaic installation system in Embodiment 1. The specific method includes:

[0085] S100, calculating a target value of the sinking depth of the airbag body 1 and a target value of the amount of gas and / or liquid inside the cabin 13 according to environmental parameters of a target installation area of ​​the water surface photovoltaic installation system;

[0086] S200, controlling the opening 131 of each cabin 13 to open, so that external gas and / or liquid enter the cabin 13, until the amount of gas and / or liquid in the cabin 13 reaches a target value;

[0087] S300, when the airbag body 1 includes a plurality of cabins 13, setting an air pressure warning value for each cabin 13 according to the different positions of the different cabins 13; and setting an overall air pressure warning value according to the air pressure warning values ​​of the different cabins 13;

[0088] S400, detecting the air pressure value of each cabin 13 by the cabin detection device 62 on the cabin 13, and calculating the overall air pressure value;

[0089] S410, when the air pressure value of the cabin 13 is lower than the air pressure warning value, and the overall air pressure value is not lower than the overall air pressure warning value, a first-level warning signal is issued through the control terminal 61 of the water surface photovoltaic installation system;

[0090] S420, when the air pressure value of the cabin 13 is lower than the air pressure warning value, and the overall air pressure value is lower than the overall air pressure warning value, a second-level warning signal is issued through the control terminal 61 of the water surface photovoltaic installation system; the level of the second-level warning signal is higher than the level of the first-level warning signal.

[0091] The specific steps of the method are shown in the following figure: Fig.14 As shown. In actual applications, the installation and operation of the water surface photovoltaic installation system are closely related to the water depth, water environment and weather conditions of the water area in the target area of ​​the water surface photovoltaic installation system. Therefore, in step S100, it is necessary to obtain the environmental parameters of the target installation area of ​​the photovoltaic installation system. For example, in a specific embodiment, when it is predicted that there will be strong winds in the target installation area, it may be necessary to increase the target value of the depth of the airbag body 1 submerged in the water to enhance the stability of the photovoltaic installation system on the water surface. When the target value of the sinking depth of the airbag body 1 is increased, the inflation amount and the amount of liquid injected into the cabin 13 in the airbag body 1 are adjusted accordingly.

[0092] In a specific embodiment, when there are multiple cabins 13 in the airbag body 1, the overall coping ability of the airbag body 1 in the face of external impact can be enhanced, and the airbag body 1 can be prevented from being damaged and collapsing as a whole. In step S300, since different cabins 13 are subjected to different forces and may have different sizes, the air pressure warning values ​​corresponding to different cabins 13 may be different.

[0093] In actual application, when one of the multiple cabins 13 in the airbag body 1 is damaged, the supporting force of the airbag body 1 can still be maintained by the undamaged cabin 13. At this time, the preset maintenance process is entered, and the staff can repair the damaged cabin 13 while the water surface photovoltaic installation system is working normally, which can effectively improve the service life and use efficiency of the water surface photovoltaic installation system. When facing a more complex external environment, it is still necessary to detect the real-time situation of each cabin 13 in the airbag body 1 or detect it multiple times, so that the staff can be notified in time when the water surface photovoltaic installation system is damaged.

[0094] In a specific embodiment, it also includes:

[0095] S500, when the airbag body 1 has only one cabin 13, setting an overall air pressure warning value for the cabin 13;

[0096] S510, detecting the air pressure value of the cabin 13 by the cabin detection device 62 on the cabin 13, and calculating the overall air pressure value;

[0097] S520, detecting the air pressure value of the cabin 13 by the cabin detection device 62 on the cabin 13, and calculating the overall air pressure value;

[0098] S530: When the overall air pressure value is lower than the overall air pressure warning value, the control terminal 61 of the photovoltaic installation system sends a highest level warning signal.

[0099] In actual application, when there is only one cabin 13 in the airbag body 1, when there is an operating problem in this cabin 13, it is necessary to immediately issue an alarm and enter a preset maintenance process.

[0100] The present embodiment provides a water surface photovoltaic installation system and an application method thereof, which is applicable to any one of the water surface photovoltaic installation systems in the aforementioned technical solutions. The target value of the sinking depth of the airbag body and the target value of the gas volume and / or liquid volume inside the cabin are calculated by detecting the environmental parameters of the target installation area. By intelligently constructing and intelligently controlling the cabin, the intelligent control of the operation of the airbag body is further realized, thereby improving the overall operation automation and intelligence of the water surface photovoltaic installation system.
