[0010] By adopting the above technical scheme, the cylindrical part is used to connect the lower end of the second rack and the expansion part. When the second rack moves vertically downward, it can synchronously drive the cylindrical part and the expansion part to move downward, so that the expansion part can pass through the cavity of the base body and be inserted into the base bed below the base body. By increasing the contact area with the base bed, the friction is increased and the support stability is improved; in the process of the expansion part moving downward, the top part at the bottom of the base body is aligned with the center of the circle surrounded by the several expansion parts, and the opening degree of the several expansion parts can be increased in the process of the cylindrical part and the top part approaching each other, so that the expansion part can be inserted into the base bed at an angle. Compared with the vertically arranged expansion part, the expansion part inserted into the base bed at an angle can optimize the vertical limiting effect, improve the fixing stability of the photovoltaic bracket, and enhance the reliability of the structure; the partition arranged at the bottom of the base body helps to separate the two adjacent expansion parts from each other, thereby improving the fixing effect of the photovoltaic bracket.

[0011] Optionally, a support portion is provided at the lower end of the cylindrical portion, the support portion is in a truncated cone shape, the diameter of the upper end surface of the support portion is smaller than the diameter of the lower end surface of the support portion, the upper ends of the plurality of expansion portions are distributed on the outer circumference of the support portion, the diameter of the lower end surface of the support portion is larger than the diameter of the upper end surface of the support portion, the upper end of the expansion portion is hingedly connected to the lower end of the cylindrical portion, so that the area of ​​the circle enclosed by the lower ends of the plurality of expansion portions is larger than the area of ​​the circle enclosed by the upper ends of the plurality of expansion portions, the expansion portion is inclined, and the top of the top sub-piece is provided with a spherical The spherical surface has a width less than or equal to the minimum diameter of a circle surrounded by the lower ends of the expansion parts, and a width greater than the diameter of the lower end surface of the support part, so that when the insert moves downward, the top dividing member can push the lower ends of the expansion parts to separate from each other; the insert includes a limiting ring and a connecting part arranged in the cavity, one end of the connecting part is connected to the base body, the limiting ring is arranged at the other end of the connecting part, the limiting ring is slidably sleeved on the outer periphery of the insert, and the limiting ring is used to bring the expansion parts together.

[0012] By adopting the above technical scheme, the truncated cone-shaped support part is used to tilt the expansion part so that the top part can be inserted into the circle surrounded by the lower end of the expansion part, so that the top part moves from the lower end of the expansion part to the upper end of the expansion part through the relative movement between the expansion part and the top part, and the lower end of the expansion part rotates around the upper end, so that the inclination of the expansion part is continuously increased, and the top part can push the expansion part to spread around so that it can be radially inserted into the base bed; the top of the top part is spherical, and through the width setting, it can reduce the risk of jamming when the expansion part and the top part contact while opening the expansion part; the limit ring can ensure that the expansion part remains in a convergent state in the initial state, avoiding the expansion part from being expanded prematurely when it is not inserted into the base bed; when the second rack moves upward, the limit ring supported by the connection part and sleeved on the outer periphery of the insert can gather the opened expansion part, so that when the expansion part is inserted into the base bed, the inclination can be gradually increased, which is convenient for insertion into the base bed, and effectively improves the reliability and stability of the insert into the base bed.

[0013] Optionally, the base assembly further includes an anchor, the upper end of the anchor is connected to the bottom end of the base body, and the lower end of the anchor is used to be hooked and inserted into the base.

[0014] By adopting the above technical solution, the provision of anchors enables the base assembly to be more firmly fixed to the base bed on the seabed, thereby enhancing the stability of the photovoltaic bracket and reducing the risk of displacement of the photovoltaic bracket due to factors such as ocean currents.

[0015] Optionally, the adjustment assembly further includes a tensioning member, and a plurality of the base assemblies are provided, and the plurality of base assemblies are arranged in pairs in a group. In a group of the base assemblies, the anchor of one base body is arranged at the bottom end of a side away from another base body. In a group of the base assemblies, the two ends of the tensioning member are respectively connected to the upper end of one base body and the lower end of another base body, and the tensioning member is flexible.

[0016] By adopting the above technical solution, the base components are grouped in pairs, which helps to improve the overall stability of the photovoltaic bracket; the force of seawater on the base body is mainly on the outside of a group of base components, so that the anchor is provided on both sides of the two base components, and the flexible tensioning member is respectively connected to the upper and lower ends of the two base bodies, so that when the first base body is subjected to the thrust of seawater toward the second base body, the tensioning member can pull the upper end of the second base body, which helps to make the second anchor more deeply inserted into the base bed, so that the stability of the second base body is improved, thereby improving the stability of the first base body in the group, and reducing the risk of displacement or tipping of the photovoltaic assembly; the flexible tensioning member can prevent thrust from being generated between the two base bodies to affect the stability.

[0017] Optionally, the adjustment assembly also includes a clip and a telescopic member, the first rack is provided with a limit groove, the limit groove extends vertically, the support body is provided with an avoidance groove, the avoidance groove extends horizontally, the clip is slidably connected to the avoidance groove, and the telescopic member is used to drive the clip to slide in the avoidance groove, so that the clip can be selectively clipped to the limit groove to limit the downward movement of the first rack.

[0018] By adopting the above technical solution, the clamping part is slidably arranged in the avoidance groove, and can be driven by the telescopic part to extend into the limiting groove, so as to limit the first rack, so that the first rack will not move down frequently after moving up, causing repeated insertion of the insert and affecting the reliability after insertion; and, limiting the upward movement of the first rack can keep the expansion part in a radially open state on the base bed, increase the force-bearing area, and improve the stability and reliability of the photovoltaic bracket in seawater.

[0019] Optionally, the fixed end of the telescopic member is connected to the bottom of the avoidance groove away from the first rack, and the movable end of the telescopic member is connected to the clamping member. The telescopic member drives the clamping member to extend and retract, so that the clamping member can selectively clamp the limiting groove.

[0020] By adopting the above technical solution, the telescopic part serves as a driving structure, which can drive the clamping part to slide horizontally in the avoidance groove, so that when the floating component drives the photovoltaic component to float up, the first rack can stably extend out of the supporting body. When the photovoltaic component needs to move downward, the telescopic part can drive the clamping part to retract, so that the first rack can be reset and moved downward, thereby improving the stability of the photovoltaic bracket by lowering the height of the photovoltaic component.

[0021] Optionally, a detection component is also included, which includes a water storage tank, a liquid level sensor and a control component. The water storage tank is arranged on one side of the floating component, and a plurality of leakage holes are arranged at the bottom of the water storage tank. The liquid level sensor is arranged on the side wall of the water storage tank. The liquid level sensor and the telescopic component are electrically connected to the control component. When the support portion abuts against the top component, the second rack reaches the maximum downward displacement, the first rack reaches the maximum upward displacement, the limit groove is aligned with the telescopic component, and the control component extends the telescopic component; after the liquid level sensor detects that the water level in the water storage tank is lower than the preset water level and lasts for a preset time, the control component retracts the telescopic component to return to its original position.

[0022] By adopting the above technical solution, the detection component can monitor the water level changes in the water storage tank in real time. When the sea water rises and the first rack is in an extended state and the support part abuts the top sub-component, the limit groove is aligned with the telescopic part, and the control part controls the telescopic part to extend, so that the clamping part is clamped in the limit groove, so that the first rack remains in a state of extending upward from the supporting body, thereby ensuring the stability of the photovoltaic bracket; when the water level drops below the preset water level and lasts for a preset time, it means that the water level has dropped, and the control part controls the telescopic part to retract, so that the clamping part is disengaged from the limit groove, and the first rack can move downward, thereby improving the stability of the photovoltaic bracket by lowering the height of the photovoltaic component; this automatic adjustment mechanism effectively improves the ability of the photovoltaic bracket to resist water level changes, and enhances its adaptability and reliability in complex underwater environments.

[0023] Optionally, the support assembly is offset on the base body, and the support assembly is arranged close to a side of the base body where the anchor is provided.

[0024] By adopting the above technical solution, since the support assembly is biased to the side close to the base body where the anchor is provided, the stability of the photovoltaic bracket in the seabed base can be enhanced, and the risk of the anchor being detached from the base due to water flow impacting the support assembly can be reduced, thereby reducing the possibility of the photovoltaic bracket being offset or tilted, and the stability of the photovoltaic bracket on the seabed base is enhanced; at the same time, the support assembly is arranged above the anchor, which helps to use the gravity of the support assembly to enable the anchor to be more effectively hooked into the base, thereby further improving the overall stability of the photovoltaic bracket.

[0025] Optionally, the adjustment assembly also includes a first elastic member and a second elastic member, wherein two ends of the first elastic member are respectively connected to the lower end of the first rack and the bottom of the support body, and two ends of the second elastic member are respectively connected to the upper end of the rack assembly and the top of the support body, and the first elastic member drives the first rack to return to the support body, and the second elastic member drives the rack assembly to return to the support body.

[0026] By adopting the above-mentioned technical solution, the setting of the first elastic member and the second elastic member can effectively drive the first rack and the rack assembly to reset into the supporting body, thereby realizing the automatic reset of the photovoltaic bracket after the floating assembly drives the photovoltaic assembly to float up, which helps to improve the stability and reset accuracy of the adjustment assembly, thereby improving the reliability and stability of the photovoltaic bracket during use.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1 -Attached Figure 7 The present application is further described in detail. In this embodiment, if not clearly specified, "connected", "connected" and "fixed" are understood in a broad sense, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection and interaction between two elements, etc., which can be understood according to the specific circumstances.

[0037] In the present application, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or the first and second features being in contact not directly but through another feature between them. Moreover, in the description of the present embodiment, the terms "above", "below", "right", etc., the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. Unless otherwise specified, the orientation words used in the present application, such as "inside" and "outside", refer to the contours of the corresponding parts themselves.

[0038] like Figure 1 As shown, the embodiment of the present application discloses a photovoltaic support made of basalt fiber material (hereinafter referred to as "photovoltaic support"). The photovoltaic support includes a base component 1, a support component 2, a floating component 3 and an adjustment component 4, which are used to set up a photovoltaic component 100 on a seabed.

[0039] The weight of the base assembly 1 is greater than or equal to the preset weight, which is the weight value that enables the photovoltaic assembly 100 to be stably supported on the base bed, so as to act as a pile sinker. The base assembly 1 is arranged on the base bed. The base assembly 1 has sufficient weight to enable the support assembly 2 arranged thereon to be stably arranged on the base bed on the seabed through the sinking effect of the weight. The support assembly 2 plays a supporting role, so that the photovoltaic assembly 100 can be located above the sea surface for more time, thereby receiving light and converting it into electrical energy.

[0040] like Figure 1 and Figure 2 As shown, the lower end of the support assembly 2 is connected to the base assembly 1, and the support assembly 2 includes a support body 21, which is hollow and made of basalt fiber material. The floating assembly 3 is used to support the photovoltaic assembly 100, and the floating assembly 3 can drive the photovoltaic assembly 100 to float. The floating assembly 3 is arranged on the lower side of the photovoltaic assembly 100, and the adjustment assembly 4 is arranged in the hollow support body 21. The photovoltaic assembly 100 is connected to the adjustment assembly 4, so that the photovoltaic assembly 100 can float under high tide and other conditions, reducing the damage caused by the seawater submerging the photovoltaic assembly 100 and the problem of reduced light, which helps to improve the life and power generation of the photovoltaic assembly 100.

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, the adjustment assembly 4 is arranged in the support body 21, and the adjustment assembly 4 includes a first rack 41, a rack assembly and a gear 43. A first slide groove is provided on the inner side of the first side wall of the support body 21, and a second slide groove is provided on the inner side of the second side wall of the support body 21. The first rack 41 is slidably connected to the first slide groove, and the upper end of the first rack 41 is used to support the photovoltaic assembly 100. The rack assembly is slidably connected to the second slide groove, so that the first rack 41 and the rack assembly can only move vertically. The gear 43 is rotatably connected to the third side wall of the support body 21 through the damping shaft, and the first rack 41 and the rack assembly are both meshed with the gear 43. The movement direction of the first rack 41 is opposite to that of the rack assembly. When the seawater level rises, the floating assembly 3 drives the photovoltaic assembly 100 to float up, which can drive the first rack 41 to extend upward from the upper end of the support body 21, so that the rack assembly can extend downward from the lower end of the support body 21, and pass through the bottom of the base assembly 1 and insert into the base bed. When the floating assembly 3 drives the photovoltaic assembly 100 to float, the first rack 41 of the adjusting assembly 4 extends upward from the upper end of the supporting body 21 to increase the height of the photovoltaic assembly 100; after the water level of the seawater drops, the buoyancy of the floating assembly 3 disappears, and the gravity of the photovoltaic assembly 100 can overcome the sum of the friction between the first rack 41 and the rack assembly and the gear 43 and the resistance of the damping shaft, so that the adjusting assembly 4 can be reset by the gravity of the photovoltaic assembly 100, so that the first rack 41 moves down, the rack assembly moves up, and the photovoltaic assembly 100 moves down. The floating assembly 3 enables the photovoltaic assembly 100 to automatically adjust its height according to the change of the water level, ensuring that the photovoltaic assembly 100 can maintain a high working efficiency at different water levels. At the same time, the first rack 41 moves in the opposite direction to the rack assembly. Through the meshing action of the gear 43, the rack assembly can extend downward from the lower end of the supporting body 21 and pass through the bottom of the base assembly 1 and stably insert into the base bed, thereby increasing the contact area with the base bed and helping to enhance the stability of the photovoltaic bracket.

[0042] The adjustment component 4 is made of basalt fiber material. The support component 2 and the adjustment component 4 made of basalt fiber material not only have sufficient strength, but also have good corrosion resistance, so they can work stably for a long time on the seabed and extend the service life of the photovoltaic bracket. The damping shaft can use an existing structure to prevent the gear 43 from rotating at will, so that the gear 43 can only be driven when the buoyancy of the tide is large enough to move the first rack 41 upward, avoiding frequent shaking up and down under the action of seawater. The photovoltaic assembly 100 includes a photovoltaic panel, a support structure and a hoop, the photovoltaic panel is arranged on the upper side of the support structure, the lower side of the support structure is connected to the upper end of the first rack 41, the floating assembly 3 can be a plate-like member with buoyancy, so that the floating assembly 3 is penetrated in the support structure to reliably realize the floating effect, the hoop is arranged at the lower end of the support structure, and the hoop is slidably connected to the support body 21, so that the photovoltaic assembly 100 can move up and down. The horizontal width of the first rack 41 can be set as needed to ensure sufficient support force.

[0043] like Figure 2 , Figure 3 and Figure 4 As shown, optionally, the adjustment assembly 4 further includes a first elastic member 47 and a second elastic member 48, and both the first elastic member 47 and the second elastic member 48 can be springs. The two ends of the first elastic member 47 are respectively connected to the lower end of the first rack 41 and the bottom of the support body 21, and the two ends of the second elastic member 48 are respectively connected to the upper end of the rack assembly and the top of the support body 21. The first elastic member 47 drives the first rack 41 to reset into the support body 21, and the second elastic member 48 drives the rack assembly to reset into the support body 21. The provision of the first elastic member 47 and the second elastic member 48 can effectively drive the first rack 41 and the rack assembly to reset into the support body 21, thereby realizing the automatic reset of the photovoltaic bracket after the floating assembly 3 drives the photovoltaic assembly 100 to float, which helps to improve the stability and reset accuracy of the adjustment assembly 4, thereby improving the reliability and stability of the photovoltaic bracket during use.

[0044] like Figure 2 , Figure 4 and Figure 5As shown, optionally, the rack assembly includes a second rack 42 and an insert 44 for inserting into the base bed, the insert 44 is arranged at the lower end of the second rack 42, and the second rack 42 is meshed with the gear 43. The insert 44 includes a cylindrical portion 441 and a plurality of expansion portions 442, the upper end of the cylindrical portion 441 is connected to the lower end of the second rack 42, and the lower end surface of the cylindrical portion 441 is circumferentially distributed with a plurality of expansion portions 442, and the upper end of the expansion portion 442 is connected to the lower end surface of the cylindrical portion 441. The cylindrical portion 441 is used to connect the lower end of the second rack 42 and the expansion portion 442. When the second rack 42 moves vertically downward, it can synchronously drive the cylindrical portion 441 and the expansion portion 442 to move downward, so that the expansion portion 442 can pass through the cavity of the base body 11 and be inserted into the base bed below the base body 11, thereby increasing the contact area with the base bed, increasing friction, and improving support stability. During the downward movement of the expansion part 442, the top part 12 at the bottom of the base body 11 is aligned with the center of the circle surrounded by the expansion parts 442. As the cylindrical part 441 and the top part 12 continue to approach each other, the opening degree of the expansion parts 442 can be increased, so that the expansion part 442 can be inserted into the base bed at an angle.

[0045] like Figure 4 , Figure 5 and Figure 6 As shown, the base assembly 1 includes a base body 11, and a cavity is provided in the base body 11. A top part 12 and a plurality of partitions 13 are provided in the cavity of the base body 11. The top part 12 is provided at the bottom of the base body 11. The top part 12 cooperates with the insert 44 so that when the insert 44 moves downward, the top part 12 pushes the lower ends of the plurality of expansion parts 442 to separate from each other. The partition 13 is located between two adjacent expansion parts 442 so that the expansion parts 442 can be separated from each other. The expansion parts 442 are used to be inserted radially into the base bed. Compared with the vertically arranged expansion parts 442, the expansion parts 442 that are inclined and radially inserted into the base bed can optimize the vertical limiting effect, improve the fixing stability of the photovoltaic bracket, and enhance the reliability of the structure. The length of the expansion part 442 is set according to the use requirements to ensure that it has sufficient insertion depth.

[0046] like Figure 4 , Figure 6 and Figure 7As shown, the partition 13 provided at the bottom of the base body 11 helps to separate the two adjacent expansion parts 442 from each other, thereby improving the fixing effect of the photovoltaic support. The base body 11 can be made of concrete to provide sufficient gravity so that the photovoltaic assembly 100 can be stably erected on the base bed of the seabed. The top of the partition 13 is an arc or an inclined sharp angle to reduce the risk of getting stuck when contacting the lower end of the expansion part 442. The expansion part 442 can be a rod-shaped member with a rounded lower end to avoid getting stuck when contacting the top partition 12. The expansion part 442 and the cylindrical part 441 can also adopt an integrated structure, and the expansion part 442 is inclined and made of a material with a certain elasticity so that the expansion part 442 can continue to expand relatively. When the expansion part 442 and the cylindrical part 441 are rotatably connected, a spring is provided between the expansion parts 442, which can be provided on the sides of the two adjacent expansion parts 442 to limit the expansion angle so that the expansion part 442 has an interaction force after expansion to avoid looseness. It is understandable that the plurality of expansion portions 442 are initially radially arranged before contacting the top part 12 , and after the expansion portions 442 contact the top part 12 , the radiation degree of the plurality of expansion portions 442 can be increased so that the expansion portions 442 can function reliably.

[0047] like Figure 4 , Figure 5 and Figure 6As shown, optionally, a support portion 443 is provided at the lower end of the cylindrical portion 441, and the support portion 443 is in a truncated cone shape, and the inclination angle of its side is set as required. The diameter of the upper end surface of the support portion 443 is smaller than the diameter of the lower end surface of the support portion 443, the upper ends of the plurality of expansion portions 442 are distributed on the outer periphery of the support portion 443, the diameter of the lower end surface of the support portion 443 is larger than the diameter of the upper end surface of the support portion 443, and the upper end of the expansion portion 442 is hinged to the lower end of the cylindrical portion 441, so that the area of ​​the circle enclosed by the lower ends of the plurality of expansion portions 442 is larger than the area of ​​the circle enclosed by the upper ends of the plurality of expansion portions 442. The truncated cone-shaped support portion 443 is used to tilt the expansion portion 442 so that the top portion 12 can be inserted into the circle surrounded by the lower end of the expansion portion 442, thereby allowing the top portion 12 to move from the lower end of the expansion portion 442 to the upper end of the expansion portion 442 through relative movement between the expansion portion 442 and the top portion 12, and the lower end of the expansion portion 442 rotates around the upper end, thereby continuously increasing the inclination of the expansion portion 442, and the top portion 12 can push the expansion portion 442 to spread out in all directions so that it can be radially inserted into the base bed. The expansion part 442 is arranged at an angle, and a spherical surface is arranged at the top of the top part 12. The width of the spherical surface is less than or equal to the minimum diameter of the circle surrounded by the lower ends of the expansion parts 442, that is, when the expansion parts 442 are gathered together, the minimum diameter of the circle surrounded by the lower ends of the expansion parts 442. The width of the spherical surface is greater than the diameter of the lower end surface of the support part 443, so that when the insert 44 moves downward, the top part 12 can push the lower ends of the expansion parts 442 to separate from each other. The top of the top part 12 is spherical, and by setting the width, the expansion part 442 can be opened while reducing the risk of jamming when the expansion part 442 contacts the top part 12. When the first rack 41 rises to the highest position and the second rack 42 falls to the lowest position, the lower end surface of the support part 443 abuts against the top part 12.

[0048] like Figure 4 , Figure 5 and Figure 6 As shown, the insert 44 includes a stop ring 444 and a plurality of connecting parts 445 disposed in the cavity. One end of the connecting part 445 is connected to the base body 11, and the stop ring 444 is disposed at the other end of the connecting part 445. The stop ring 444 is slidably sleeved on the outer periphery of the insert 44, and the stop ring 444 is used to gather the plurality of expansion parts 442. The stop ring 444 can ensure that the expansion part 442 remains in a convergent state in the initial state, and prevents the expansion part 442 from being prematurely expanded when it is not inserted into the base bed. The connecting part 445 can be a rod-shaped member.

[0049] When the second rack 42 moves upward, the limit ring 444 supported by the connection part 445 and sleeved on the outer periphery of the insert 44 can gather the opened expansion part 442, so that the expansion part 442 can gradually increase its inclination when inserted into the base bed, which is convenient for insertion into the base bed and effectively improves the reliability and stability of the insert 44. The rotation connection between the expansion part 442 and the support part 443 can also be achieved by a damping shaft, which limits the free rotation of the expansion part 442, so that the expansion part 442 can only be opened by the top part 12 and gathered by the limit ring 444, thereby improving reliability.

[0050] like Figure 2 and Figure 4 As shown, optionally, the base assembly 1 further includes an anchor 14. The upper end of the anchor 14 is connected to the bottom end of the base body 11, and the lower end of the anchor 14 is used to hook and insert into the base. The anchor 14 can be a ship anchor structure, and the specific structure of the anchor 14 is not limited. The provision of the anchor 14 enables the base assembly 1 to be more firmly fixed on the base bed of the seabed, enhances the stability of the photovoltaic bracket, and reduces the risk of displacement of the photovoltaic bracket due to factors such as ocean currents.

[0051] Optionally, the support assembly 2 is offset on the base body 11, and the support assembly 2 is arranged close to the side of the base body 11 where the anchor 14 is provided. Since the support assembly 2 is offset to the side close to the base body 11 where the anchor 14 is provided, the stability of the photovoltaic bracket in the seabed bed can be enhanced, and the risk of the anchor 14 being disengaged from the bed due to the impact of the water flow on the support assembly 2 can be reduced, thereby reducing the possibility of the photovoltaic bracket being offset or tilted, and the stability of the photovoltaic bracket on the seabed bed is enhanced. At the same time, the support assembly 2 is arranged above the anchor 14, which helps to increase the downward pressure on the anchor 14 through the gravity of the support assembly 2, so that the anchor 14 can be more effectively hooked into the base, further improving the overall stability of the photovoltaic bracket. The support assembly 2 also includes embedded parts, and the support body 21 can achieve a stable connection with the base body 11 through the embedded parts embedded in the base body 11.

[0052] like Figure 1 , Figure 2 and Figure 4 As shown, optionally, the adjustment component 4 also includes a tensioning member 45. The photovoltaic support is provided with multiple base components 1, and multiple base components 1 are arranged in pairs relative to each other in a group, and the base components 1 are arranged in pairs, which helps to improve the overall stability of the photovoltaic support. In a group of base components 1, the anchor 14 of a base body 11 is arranged at the bottom end of a side away from another base body 11; in a group of base components 1, the two ends of the tensioning member 45 are respectively connected to the upper end of one base body 11 and the lower end of another base body 11, and the tensioning member 45 is flexible.

[0053] like Figure 1 , Figure 2 and Figure 4 As shown, the force of seawater on the base body 11 is mainly on the outside of a group of base components 1, and because the photovoltaic component 100 is arranged on the top, the force-bearing area is large, which will make the force on the top of the photovoltaic bracket greater than the force on the bottom, causing the risk of the photovoltaic bracket to easily tip over. The anchor 14 is provided on both sides of the two base components 1, and the flexible tensioning member 45 is respectively connected to the upper end and the lower end of the two base bodies 11, so that when the first base body 11 in a group of base bodies 11 is subjected to the thrust of seawater toward the second base body 11, the tensioning member 45 can pull the upper end of the second base body 11, which helps to make the second anchor 14 inserted deeper into the base bed, so that the stability of the second base body 11 is improved, thereby improving the stability of the first base body 11 in the group, and reducing the risk of displacement or tipping of the photovoltaic component 100. The tensioning member 45 can be a flexible member such as a flexible rope that can only achieve pulling, and the flexible tensioning member 45 can prevent thrust from being generated between the two base bodies 11 to affect stability.

[0054] In one embodiment, optionally, the adjustment assembly 4 further includes a clamping member and a telescopic member 46. The first rack 41 is provided with a limit groove 411, which extends vertically. The support body 21 is provided with an avoidance groove, which extends horizontally. The clamping member is slidably connected to the avoidance groove, and the telescopic member 46 is used to drive the clamping member to slide in the avoidance groove, so that the clamping member can be selectively clamped in the limit groove 411 to limit the first rack 41 from moving downward. The clamping member can be a block structure, and one end of the clamping member away from the first rack 41 is connected to a spring, and is extended by the elasticity of the spring to achieve the effect of being clamped in the limit groove. The clamping member is slidably arranged in the avoidance groove, and can be driven by the telescopic member 46 to extend into the limit groove 411 to achieve the limitation of the first rack 41, so that the first rack 41 will not frequently move down after moving up, causing the insert 44 to be repeatedly inserted and affecting the reliability after insertion. Furthermore, the upward movement of the first rack 41 can keep the expansion part 442 radially open on the base bed, increase the force-bearing area, and improve the stability and reliability of the photovoltaic bracket in seawater. The size of the limit groove 411 can match the clamping piece, so that the clamping piece can be inserted into the limit groove 411 without causing the first rack 41 to move up and down significantly.

[0055] like Figure 1 , Figure 2 and Figure 4As shown, optionally, the fixed end of the telescopic member 46 is connected to the bottom of the groove on one side of the avoidance groove away from the first rack 41, and the movable end of the telescopic member 46 is connected to the clamping member (not shown in the figure), and the telescopic member 46 drives the clamping member to extend and retract, so that the clamping member can selectively clamp the limit groove 411 and achieve the function of resetting and releasing the clamping. The telescopic member 46 can be a structure that can achieve telescoping, such as an electric telescopic rod. As a driving structure, the telescopic member 46 can drive the clamping member to slide horizontally in the avoidance groove, so that when the floating component 3 drives the photovoltaic component 100 to float up, the first rack 41 can stably extend out of the support body 21. When the photovoltaic component 100 needs to move down, the telescopic member 46 can drive the clamping member to retract, so that the first rack 41 can be reset and moved down, thereby improving the stability of the photovoltaic bracket by reducing the height of the photovoltaic component 100.

[0056] like Figure 1 , Figure 2 and Figure 4 As shown, optionally, the photovoltaic bracket also includes a detection component, which includes a water storage tank 51, a liquid level sensor 52 and a control component. The water storage tank 51 is arranged on one side of the floating component 3 for sensing the water level. It is understandable that the buoyancy provided by the floating component 3 is large enough to drive the related structures to float. A plurality of leakage holes are provided at the bottom of the water storage tank 51, and the liquid level sensor 52 is provided on the side wall of the water storage tank 51. The liquid level sensor 52 and the telescopic component 46 are electrically connected to the control component. When the water level gradually rises, the adjustment component 4 will drive the photovoltaic component 100 to rise continuously, and the telescopic component 46 will not extend during this process. When the seawater rises and the photovoltaic assembly 100 is in a floating state, and the lower end surface of the support part 443 abuts the top sub-component 12, the second rack 42 reaches the maximum downward displacement, the first rack 41 reaches the maximum upward displacement, the limit groove 411 is aligned with the telescopic member 46, and the control member extends the telescopic member 46, so that the clamping member extends into the limit groove 411, so that the first rack 41 remains in a state of extending upward from the support body 21, ensuring the stability of the photovoltaic bracket. Specifically, a pressure sensor can be provided on the lower end surface of the support part 443, and the pressure sensor is used to measure the abutment pressure. After the support part 443 contacts the top sub-component 12, it means that the second rack 42 reaches the maximum downward displacement position, the first rack 41 reaches the maximum upward displacement position, and the pressure sensor is electrically connected to the control member. When the pressure value of the pressure sensor increases to the preset pressure value, the control member controls the telescopic member 46 to extend, and the telescopic member 46 can extend into the limit groove 411. By increasing the height of the photovoltaic module 100, the possibility of the photovoltaic module 100 being exposed to light is increased, or after the water level of the seawater drops, the photovoltaic module 100 can be exposed to sunlight more quickly, thereby improving the power generation efficiency. The pressure sensor can be a waterproof type, and an existing structure can be selected according to needs.

[0057] like Figure 1 , Figure 2 and Figure 4As shown, when the liquid level sensor 52 detects that the water level in the water storage tank 51 is less than the preset water level and maintains the preset time, it means that the seawater level has dropped. The control component retracts the telescopic component 46 to return to its original position, so that the photovoltaic assembly 100 can move downward to improve stability, so that the height of the photovoltaic assembly 100 can be adjusted according to the height of the water level. The liquid level sensor 52 can be a magnetic flap liquid level gauge, or other types of liquid level gauges can be selected as needed; the setting direction of the liquid level sensor 52 is determined according to actual conditions, and can be placed vertically in the water storage tank 51; the length of the preset time is determined according to actual use. The control component can be a data processing center, controller or computer that can realize the reception and transmission of signals and instructions, and an existing structure can be selected as needed. When the water level drops below the preset water level and lasts for a preset time, the control component controls the telescopic component 46 to retract, so that the clamping component disengages from the limiting groove 411, and the first rack 41 can move downward, thereby improving the stability of the photovoltaic bracket by lowering the height of the photovoltaic component 100; this automatic adjustment mechanism effectively improves the photovoltaic bracket's ability to resist water level changes, and enhances its adaptability and reliability in complex underwater environments.

[0058] It can be understood that the photovoltaic bracket also includes necessary structures for connection, support, driving, positioning, limiting, sealing and control functions so that the photovoltaic bracket can operate normally; the parameters such as the shape, size, material and setting quantity of each part of the photovoltaic bracket can be determined according to needs as long as the corresponding functions can be realized.

[0059] The implementation principle of a photovoltaic support made of basalt fiber material in the embodiment of the present application is as follows: the base component 1 has sufficient weight to enable the support component 2 arranged thereon to be stably erected on the base bed of the seabed through the sinking effect of the weight, and the support component 2 enables the photovoltaic component 100 to be arranged above the sea surface, so as to receive light and convert it into electrical energy; a floating component 3 is arranged on the lower side of the photovoltaic component 100, and an adjusting component 4 is arranged in the hollow supporting body 21, and the photovoltaic component 100 is connected to the adjusting component 4, so that the photovoltaic component 100 can float up in the case of high tide, thereby reducing the problem of damage caused by seawater submerging the photovoltaic component 100 and reduced light, which helps to improve the life and power generation of the photovoltaic component 100; when the seawater level rises and the floating component 3 drives the photovoltaic component 100 to float up, the first rack 41 of the adjusting component 4 extends upward from the upper end of the supporting body 21, thereby improving the photovoltaic The height of the photovoltaic component 100; after the water level of the sea drops and the buoyancy disappears, the adjusting component 4 is reset by the gravity of the photovoltaic component 100, and the height of the photovoltaic component 100 drops. The floating component 3 enables the photovoltaic component 100 to automatically adjust its height according to the change of the water level, ensuring that the photovoltaic component 100 can maintain a high working efficiency at different water levels; at the same time, the first rack 41 is opposite to the moving direction of the rack component, and through the meshing action of the gear 43, the rack component can extend downward from the lower end of the support body 21 and pass through the bottom of the base component 1 and stably insert into the base bed, thereby increasing the contact area with the base bed and helping to enhance the stability of the photovoltaic bracket; the support component 2 and the adjusting component 4 made of basalt fiber material not only have sufficient strength, but also have good corrosion resistance, so they can work stably for a long time on the seabed, thereby extending the service life of the photovoltaic bracket.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
