[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0027] Example 1

[0028] like Figure 1 As shown, the present invention's water-floating adjustable photovoltaic support 10 includes an inclined beam 11, with support columns disposed at the front and rear ends of the inclined beam 11. The upper ends of the two support columns are hingedly connected to the inclined beam 11. The lower end of one of the support columns is provided with a connection structure for fixed connection to a foundation 17, while the lower end of the other support column is fixedly connected to a floating raft 14. In this embodiment, purlins 16 for mounting photovoltaic panels 15 are spaced apart on the top surface of the inclined beam 11. In this embodiment, the two support columns are a front column 12 located at the front end of the inclined beam 11 and a rear column 13 located at the rear end of the inclined beam 11. The floating raft 14 is disposed at the lower end of the front column 12, and the lower end of the rear column 13 is fixedly connected to the foundation 17. Of course, in other embodiments, the floating raft 14 can also be disposed at the lower end of the rear column 13, with the lower end of the front column 12 fixedly connected to the foundation. This will not be described in detail here.

[0029] Thus, in actual use, the floating raft 14 is placed in the water, and the height of the floating raft 14 can be adjusted by adjusting the water level, thereby changing the position of the front column 12 relative to the rear column 13, so that the inclination angle of the inclined beam 11 is changed, such as Figure 1-2 Of course, in another embodiment of the present invention, a water injection hole is provided on the floating raft 14. In this way, water can be injected into the floating raft 14 through the water injection hole, or the water in the floating raft 14 can be pumped out through the water injection hole to adjust the weight of the floating raft 14. In this way, the position of the floating raft 14 can be adjusted even without changing the water level, thereby achieving adjustment of the inclination angle of the inclined beam 11.

[0030] In actual use, a proportional value of the maximum buoyancy of the floating raft 14 can be set to be equal to the maximum support reaction force borne by the front column 12. For example, 80% of the maximum buoyancy of the floating raft 14 can be set to be equal to the maximum support reaction force borne by the front column 12. In this way, it can be ensured that at least 20% of the volume of the floating raft 14 is exposed above the water surface. Since the support reaction force borne by the front column 12 will change with different working conditions, the volume of the floating raft 14 exposed above the water surface will change accordingly. At this time, the inclination angle of the inclined beam 11 can be obtained by observing the volume of the floating raft 14 exposed above the water surface and combining it with the water level. Of course, at this time, a pressure sensor can be installed on the bottom surface of the floating raft 14. The water pressure measured by the pressure sensor can be used to obtain the water immersion depth of the floating raft 14, and then the volume of the floating raft 14 exposed above the water surface can be obtained.

[0031] Example 2

[0032] like Figure 3 As shown, the water-floating adjustable photovoltaic support system of this embodiment includes a water area 20 and at least one water-floating adjustable photovoltaic support 10 as described in Example 1. Specifically, a floating raft 14 is located within water area 20, and the tilt angle of the inclined beam 11 is adjusted by adjusting the water level within water area 20 or the weight within the floating raft 14. Specifically, a foundation 17 is disposed within water area 20 or on the shore adjacent to water area 20 to secure the rear column 13.

[0033] Specifically, if the area of ​​the water area 20 is large and a large amount of water needs to be pumped in or out to change the water level in the water area 20, the tilt angle of the inclined beam 11 can be adjusted by adjusting the weight of the floating raft 14. Specifically, in this case, a water injection hole can be provided on the floating raft 14. In this way, water can be injected into the floating raft 14 through the water injection hole, or water in the floating raft 14 can be pumped out through the water injection hole to adjust the weight of the floating raft 14. In this way, the position of the floating raft 14 can be adjusted even without changing the water level, thereby achieving adjustment of the tilt angle of the inclined beam 11.

[0034] If the area of ​​the water area 20 is small, the tilt angles of all water-floating adjustable photovoltaic supports 10 can be adjusted simultaneously by directly changing the water level of the water area 20. Figure 3 As shown, in this application scenario, the water-floating adjustable photovoltaic support system of this embodiment further includes a water level control system for controlling the water level in the water area 20. The water level control system can be implemented in a variety of existing methods. In this embodiment, the water level control system includes a water tank 21 and a first pump 22. The first pump 22 is used to pump water from the water area 20 into the water tank 21 or pump water from the water tank 21 into the water area 20 to adjust the water level in the water area 20, thereby changing the height of the floating raft 14 and the inclination angle of the inclined beam 11.

[0035] Example 3

[0036] like Figure 4 As shown, the water-floating adjustable photovoltaic support system of this embodiment includes a water area 20 and at least one water-floating adjustable photovoltaic support 10 as described in Example 1. Specifically, a floating raft 14 is located within water area 20, and the tilt angle of the inclined beam 11 is adjusted by adjusting the water level within water area 20. Specifically, a foundation 17 is disposed within water area 20 or on the shore adjacent to water area 20 to secure the rear column 13.

[0037] In this embodiment, the water-floating adjustable photovoltaic mounting system also includes a water level control system for controlling the water level within water area 20. Specifically, water area 20 is a canal 23 that cooperates with floating raft 14. The water level control system includes an upper reservoir 24 and a lower reservoir 25. The water level of upper reservoir 24 is higher than that of canal 23, while the water level of lower reservoir 25 is lower than or equal to that of canal 23. In this embodiment, an upper control pipe 26 is provided between upper reservoir 24 and canal 23, with an upper control valve 27 installed thereon. Lower reservoir 25 is connected to canal 23. A second pump 28 is provided between upper and lower reservoirs 24, 25, for pumping water from lower reservoir 25 into upper reservoir 24. Thus, when the upper control valve 27 is opened, the water in the upper water tank 24 can automatically flow into the canal 23 under the action of potential energy to adjust the water level in the canal 23. Under the action of potential energy, the water in the canal 23 can also automatically flow into the lower water tank 25 to adjust the water level in the canal 23. When the water storage capacity in the upper water tank 24 is low, the second pump 28 is used to pump the water in the lower water tank 25 to the second pump 28 in the upper water tank 24. This ensures that the water level in the upper water tank 24 is always higher than the water level in the canal 23. In one application scenario, the second pump 28 can be activated at night when electricity consumption is low to pump water from the lower water tank 25 to the upper water tank 24, thereby achieving staggered electricity consumption.

[0038] In a preferred implementation of this embodiment, a dam 241 is provided on the side of the upper water tank 24 facing the canal 23 to prevent water in the upper water tank 24 from seeping into the canal 23 and to control the amount of water flowing from the upper water tank 24 to the canal 23 .

[0039] In this embodiment, the water level of the lower water tank 25 is equal to the water level of the water channel 23. Figure 5 As shown, in the preferred implementation of this embodiment, the water level of the lower water tank 25 can also be made lower than the water level of the canal 23. At this time, a lower control pipe 29 can be set between the lower water tank 25 and the canal 23, and a lower control valve 30 can be provided on the lower control pipe 29, so as to realize the control of the amount of water flowing from the canal 23 to the lower water tank 25.

[0040] The above-described embodiments are merely preferred embodiments for the purpose of fully illustrating the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are within the scope of protection of the present invention.
