The support beams 14 and the connecting beam 15 are both provided with equidistant third mounting holes 16. The two support beams 14 and the connecting beam 15 are fixed through the fifth bolt 17 and the third mounting hole 16. When the upper end surface of the mounting bracket 3 needs to be installed with photovoltaic panels 4 of different sizes, the spacing between the two support beams 14 can be adjusted through the fifth bolt 17, the third mounting hole 16, and the connecting beam 15, thereby realizing the overall adjustment of the length of the cross beam 12 to adapt to the installation of photovoltaic panels 4 of different sizes. At the same time, the spacing between the two floats 1 is adaptively adjusted.

[0029] In the embodiment, a plurality of auxiliary beams 18 parallel to the longitudinal beams 11 are arranged between the two longitudinal beams 11, and the auxiliary beams 18 are fixedly arranged on the upper end surfaces of each cross beam 12.

[0030] In the embodiment, the lower end surface of the connecting beam 15 is fixedly provided with a Y-shaped connecting piece 20, and the outer surface of each vertical column 2 is fixedly provided with a diagonal strut 21. The top end of each diagonal strut 21 is fixedly arranged with the Y-shaped connecting piece 20. The diagonal strut 21 can effectively increase the stability between the two vertical columns 2 and the middle cross beam 12.

[0031] In the embodiment, the float 1 is a hollow structure, and the inner bottom wall of the float 1 is fixedly provided with a reinforcing rib 22. The bottom end of the vertical column 2 extends downward into the float 1 and is fixedly arranged with the reinforcing rib 22, achieving the purpose of fixing the vertical column 2.

[0032] In the embodiment, the lower end surface of the float 1 is fixedly provided with an anchoring rope 23, and the bottom end of the anchoring rope 23 is fixedly provided with an anchoring pile 24. The anchoring rope 23 and the anchoring pile 24 mainly play a role in stabilizing the float 1, preventing the water from flowing too fast, and preventing the vertical column 2 and the mounting bracket 3 from being overturned. The anchoring pile 24 is provided in the shape of a spherical ball.

[0033] In this embodiment, the anchor rope 23, the anchor pile 24, the column 2, the longitudinal beam 11 and the cross beam 12, and the connecting piece are all made of basalt fiber composite material, which is made of basalt stone and has the advantages of corrosion resistance, high strength and light weight, can better adapt to the material requirements of the floating photovoltaic support, and effectively avoid the rusting of the installation support 3 caused by the metal structure design in the prior art.

[0034] In this embodiment, the float 1 is integrally formed of polyethylene material.

[0035] Since the float 1 is arranged in the left-right direction, the float 1 may be inclined in the front-back direction during use, and even cause a rollover. In order to solve this problem, in this embodiment, a connecting rod 25 is fixedly arranged on the front and back sides of the adjusting mechanism between the two floats 1, a support rod 26 is fixedly arranged on the outer surface of each connecting rod 25, and an adjusting cylinder 27 is fixedly arranged on the outer end of each support rod 26. During use, the adjusting cylinders 27 on the front and back sides provide buoyancy in the front-back direction, which compensates for the imbalance of the buoyancy of the two floats 1 in the front-back direction, and reduces the probability of the front and back sides of the two floats 1 rolling over.

[0036] In order to further realize the function of automatically returning to the normal position of the float 1 when the float 1 is inclined in the front-back direction, in this embodiment, a fixed rod 28 is fixedly arranged below the adjusting mechanism between the two floats 1, a vertical rod 29 is fixedly arranged on the fixed rod 28 in the up-down direction, a balance disc 30 is coaxially fixedly arranged at the bottom end of the vertical rod 29, a plurality of balance counterweights 31 are arranged on the balance disc 30 in the radial direction, a water pressure sensing device is arranged in the adjusting cylinder 27, a transmission device is arranged between the water pressure sensing device and the corresponding balance counterweight 31, the water pressure sensing device acts according to the change of the water pressure, and then drives the corresponding balance counterweight 31 to move inwards or outwards relative to the balance disc 30 in the radial direction through the transmission device, and then the displacement of the balance counterweight 31 causes the center of gravity to change to compensate for the inclination of the float 1 in the front-back direction, so that the two floats 1 have the function of automatically returning to the normal position when they are inclined. When the float 1 is inclined to the back side, the water pressure sensing device on the front side floats up, the water pressure acting on the water pressure sensing device on the front side becomes smaller, the balance counterweight 31 on the front side is driven to move outward through the transmission device, so that the center of gravity of the two floats 1 moves forward, so that the two floats 1 generate a forward inclination force to offset the tendency of the float 1 to incline to the back side.

[0037] The water pressure sensing device can use an existing water pressure sensor, which causes a micro-displacement of a diaphragm to cause a change in resistance and output a standard electrical signal through the action of water pressure; and then the standard electrical signal controls the corresponding driving motor to drive the center of gravity of the balance counterweight 31 to produce a corresponding offset. The above structure is prior art and will not be described here.

[0038] In this embodiment, the water pressure sensing device can also be realized by the following special designed mechanical mechanism: The inside of the adjusting cylinder 27 is fixedly provided with a partition plate 32, which divides the inside space of the adjusting cylinder 27 into left and right two sliding chambers, and the water pressure sensing device comprises pistons 33 respectively slidingly arranged in the left and right two sliding chambers of the adjusting cylinder 27, a compression spring 34 is fixedly arranged between the inner side surface of each piston 33 and the partition plate 32, a piston rod 35 is coaxially fixedly arranged on the outer side surface of each piston 33, the outer end of each piston rod 35 is rotationally connected with the outer end of a connecting rod 36, and the inner end of each connecting rod 36 is rotationally connected with a corresponding balance weight 31; the outer side surface of the piston 33 senses the water pressure, when the two floating buoys 1 are inclined forward, the front adjusting cylinder 27 sinks into the water to increase the depth, and then the water pressure on the outer side surface of the piston 33 increases, so that the piston 33 slides inward, the piston rod 35 moves inward driven by the piston 33, the outer ends of the two piston rods 35 move to each other driven by the two connecting rods 36, so that the inner end of the connecting rod 36 pushes the front balance weight 31 to move inward on the balance disc 30, the balance weight 31 moves the center of gravity backward, and then offsets the force of the two floating buoys 1 inclining forward; when the two floating buoys 1 are inclined forward, the rear adjusting cylinder 27 floats upward at the same time, so that the depth of the adjusting cylinder 27 in the water decreases, and then the water pressure on the outer side surface of the piston 33 decreases, so that the piston 33 moves outward under the pushing of the compression spring 34, the piston rod 35 moves outward driven by the piston 33, so that the outer ends of the two piston rods 35 move away from each other driven by the two connecting rods 36, and then the inner ends of the two connecting rods 36 pull the rear balance weight 31 outward, so that the rear balance weight 31 moves backward, and the center of gravity of the floating buoy 1 moves backward, and then offsets the force of the two floating buoys 1 inclining forward; in summary, when the two floating buoys 1 are inclined forward, the two balance weights 31 on the front move backward, the two balance weights 31 on the rear move backward, so that all the balance weights 31 on the balance disc 30 move backward, and then the center of gravity moves backward, so that the two floating buoys 1 inclining forward slowly corrects, and the purpose that the two floating buoys 1 can automatically correct when inclining forward or backward is realized.

[0039] In this embodiment, the outer end of the connecting rod 36 is fixedly provided with a vertical shaft 37 in the vertical direction, and the vertical shaft 37 is rotationally connected with the outer end of the corresponding piston rod 35, so as to realize the rotationally connecting purpose of the connecting rod 36 and the piston rod 35.

[0040] In the embodiment, a clamping groove 38 is formed in each balance weight 31, and the balance disc 30 is located in the clamping groove 38 of each balance weight 31; a guide groove 39 is formed in the lower end surface of the balance weight 31 along the radial direction of the balance disc 30, and a guide rod 40 is fixedly arranged on the lower end surface of the balance disc 30 and located in the guide groove 39; when the balance weight 31 moves, the balance weight 31 is limited by the guide groove 39 and the guide rod 40, so that the balance weight 31 moves along the radial direction of the balance disc 30.

[0041] In order to adjust the draft of the buoy 1, in the embodiment, the bottom end of the vertical rod 29 is fixedly provided with a ballast cylinder 41, the inside of the ballast cylinder 41 is divided into a front ballast chamber 42 and a rear ballast chamber 43, the front ballast chamber 42 and the rear ballast chamber 43 are provided with energy storage devices, check valves are arranged at both ends of the ballast cylinder 41, and the flow directions of the check valves are both directed to the inside of the ballast cylinder 41; in use, the buoy 1 is pressed downward, so that the draft of the buoy 1 is artificially changed, the depth of the ballast cylinder 41 in water increases, the water pressure increases, the water pressure opens the check valves to enter the front ballast chamber 42 and the rear ballast chamber 43 and compresses the energy storage devices, so that the energy storage devices are consistent with the water pressure outside the ballast cylinder 41, and the outside water stops entering the front ballast chamber 42 and the rear ballast chamber 43; at this time, the pressing of the buoy 1 is stopped, because the water enters the inside of the front ballast chamber 42 and the rear ballast chamber 43, the buoy 1 will not float to the original height, but will stay near the pressed depth, so that the draft of the buoy 1 increases, and the purpose of adjusting the draft of the buoy 1 is achieved; when the buoy 1 is arranged in a fresh water area and a sea water area, because the environments are different, the wind and wave in the sea water area are larger, the draft of the buoy 1 can be increased, so that the height of the mounting bracket 3 is reduced, and the swinging range when the buoy 1 is affected by wind is reduced (the wind-affected area is small, and the center of gravity is low, so the swinging range is reduced); by reducing the swinging range of the mounting bracket 3, the impact on the mounting bracket 3 is greatly reduced, and the service life of the mounting bracket 3 is further prolonged; in the fresh water area, because the wind and wave are small, the draft of the buoy 1 can not be adjusted, and the buoy 1 can be normally used.

[0042] In the embodiment, the energy storage device includes an energy storage spring 44 and a second pressing plate 45, and the outer end of the energy storage spring 44 is fixedly arranged with the second pressing plate 45; when the water pressure outside the ballast cylinder 41 increases and enters the ballast cylinder 41, the water pushes the second pressing plate 45 to move inward to compress the energy storage spring 44, until the elastic force of the energy storage spring 44 is consistent with the water pressure outside, the check valve is closed, and the water stops entering.

[0043] In this embodiment, the check valve includes two valve seats 46, a valve ball 47 is arranged between the two valve seats 46, and a transmission device is arranged between the valve ball 47 and the counterweight 31; the counterweight 31 pushes the valve ball 47 to move forward or backward through the transmission device, so as to realize the purpose of cooperation of the valve ball 47 with the valve seat 46 on the outside or the valve seat 46 on the inside; in normal use, the valve ball 47 cooperates with the valve seat 46 on the outside; when it is needed to adjust the draft of the buoy 1, the buoy 1 is pressed downward, the water pressure on the outside is increased, which pushes the valve ball 47 into the front ballast chamber 42 and the rear ballast chamber 43, then the pressing of the buoy 1 is stopped, because the ballast water is introduced into the front ballast chamber 42 and the rear ballast chamber 43, the buoy 1 stays at the pressed depth, so as to realize the purpose of increasing the draft of the buoy 1; when it is needed to adjust upward, the valve ball 47 needs to cooperate with the valve seat 46 on the inside, the operation mode is to continue to press the buoy 1 downward, the water pressure on the outside of the adjusting cylinder 27 is continuously increased to push the piston 33 to move inward, so that the piston 33 drives the counterweight 31 to move inward through the piston rod 35, the vertical shaft 37 and the connecting rod 36, the counterweight 31 moves inward to drive the valve ball 47 to move inward through the transmission device and cooperate with the valve seat 46 on the inside; so that the flow direction of the check valve is changed from inward to outward; then the buoy 1 is lifted upward, so as to drive the ballast cylinder 41 to move upward, the water pressure on the outside of the ballast cylinder 41 is reduced, the energy storage spring 44 in the ballast cylinder 41 pushes the second pressing plate 45 to move outward, the second pressing plate 45 pushes the water in the ballast cylinder 41 to move outward and push away the valve ball 47 to discharge the ballast cylinder 41, at this time, the buoy 1 is stopped from being lifted upward, because part of the water in the ballast cylinder 41 is discharged, the buoy 1 will not drop back to the original position, so as to realize the purpose of reducing the draft of the buoy 1; if the buoy 1 is completely lifted out and the ballast cylinder 41 is separated from the water surface, the water in the ballast cylinder 41 will be completely discharged under the pushing of the energy storage spring 44, then the buoy 1 can be moved and carried.

[0045] In this embodiment, the telescopic rod 52 comprises a sleeve 55 and an inner rod 56, the bottom end of the sleeve 55 is rotationally connected with the lower rod 51; the top end of the inner rod 56 is rotationally connected with the upper rod 53; the inner rod 56 is sleeved in the inner hole of the sleeve 55, the inner hole of the sleeve 55 is fixedly provided with a tension spring 57, the bottom end of the tension spring 57 is fixedly provided with the inner bottom wall of the inner hole of the sleeve 55, and the top end of the tension spring 57 is fixedly provided with the bottom end of the inner rod 56; when in use, when the counterweight 31 moves inward, the counterweight 31 moves inward through the transmission rod 54, the upper rod 53, the inner rod 56, the sleeve 55, the lower rod 51 and the outer rod 50 to drive the rotating shaft 49 to rotate, so that the rotating shaft 49 drives the valve ball 47 to rotate inward through the valve rod 48, so that the valve ball 47 cooperates with the inner valve seat 46; in the process of movement, when the sleeve 55 and the inner rod 56 rotate to coincide with the outer rod 50 (that is, pass through the vertical plane of the axis of the rotating shaft 49), the tension spring 57 is stretched the longest, when the sleeve 55 and the inner rod 56 pass through the vertical plane of the axis of the rotating shaft 49, the direction of the force of the tension spring 57 changes, so that the lower rod 51 rapidly rotates inward, so that the valve ball 47 cooperates with the inner valve seat 46; the working principle of the valve ball 47 rotating outward to cooperate with the outer valve seat 46 is the same.

[0046] The water depth adjustment of the ballast cylinder 41 is a range, when the valve ball 47 cooperates with the outer valve seat 46, pressing downward can increase the water depth of the buoy 1, but if the pressing depth exceeds the adjustment range, the valve ball 47 will act to cooperate with the inner valve seat 46, at this time, only the buoy 1 can be adjusted to move upward; when the buoy 1 moves upward beyond the adjustment range, the valve ball 47 will act to cooperate with the outer valve seat 46.

[0047] The working principle of the present application is as follows: two floating buoys 1 can float on the water surface, the floating buoys 1 are supported by the vertical columns 2 to install the mounting brackets 3 and the photovoltaic panels 4, so as to realize the purpose of generating electricity on the surface of water bodies such as lakes, ponds, salt ponds and offshore areas; when assembling, the total height of the first telescopic part 7 and the second telescopic part 8 is adjusted through the second mounting hole 9 and the second bolt 10, so as to adjust the inclination of the mounting bracket 3, and then adjust the inclination of the photovoltaic panel 4; the distance between the two supporting beams 14 is adjusted through the fifth bolt 17, the third mounting hole 16 and the connecting beam 15, so as to adjust the overall length of the cross beam 12, so as to adapt to the installation of photovoltaic panels 4 of different sizes, and the photovoltaic panel 4 is fixed on the mounting bracket 3 through the first pressing plate 19. When the two floating buoys 1 are inclined forward, the front adjusting cylinder 27 sinks into the water to increase the depth, and then the water pressure on the outer side of the piston 33 increases, so that the piston 33 slides inward, the piston rod 35 moves inward under the driving of the piston 33, the two connecting rods 36 move towards each other under the driving of the two piston rods 35, the inner end of the connecting rod 36 pushes the front balance weight 31 on the balance disc 30 to move inward, and the center of gravity moves backward under the cooperation of the weight, so as to offset the force of the two floating buoys 1 tilting forward; when the two floating buoys 1 are inclined forward, the rear adjusting cylinder 27 floats upward at the same time, so that the depth of the adjusting cylinder 27 in the water decreases, and then the water pressure on the outer side of the piston 33 decreases, so that the piston 33 moves outward under the driving of the compression spring 34, the piston rod 35 moves outward under the driving of the piston 33, the outer end of the two connecting rods 36 moves away from each other, and then the inner end of the two connecting rods 36 pulls the rear balance weight 31 outward, so that the rear balance weight 31 moves backward, and the center of the floating buoy 1 moves backward, so as to offset the force of the two floating buoys 1 tilting forward; as described above, when the two floating buoys 1 are inclined forward, the two balance weights 31 on the front side move backward, the two balance weights 31 on the rear side move backward, so that all the balance weights 31 on the balance disc 30 move backward, and then the center of gravity moves backward, so that the two floating buoys 1 tilting forward slowly return to the normal position, so as to realize the purpose of automatically returning to the normal position when the two floating buoys 1 are inclined forward or backward.
