4th spacing preiection is set, prevents expansion link 123 from departing from column sleeve pipe by the 3rd spacing preiection and the cooperation of the 4th spacing preiection
121 and column 122.In other embodiments, also can be respectively provided with column sleeve pipe 121, column 122 and expansion link 123 simultaneously
Spacing preiection, the present embodiment does not specifically limit.In addition, as shown in figure 4, in the present embodiment, column sleeve pipe 121, column 122 and
Expansion link 123 is cylinder, and the first spacing preiection 1211 and the second spacing preiection 1232 all circumferentially whole installations, but
It is, it should be noted that the present embodiment is not used to limit the concrete shape of column sleeve pipe 121, column 122 and expansion link 123
And the concrete form of spacing preiection, such as in other embodiments, column sleeve pipe 121, column 122 and expansion link 123 are acceptable
For square pile body or other shapes of cylinder, spacing preiection can also be spaced protruding block.
Specifically, the process that the spacing column 120 of the present embodiment rises or falls with water level is as follows：First, when on water level
When rising, the floating drum 110 swimming on the water surface 20 rises with water level and rises, and floating drum 110 rising drives be connected with floating drum to prop up
Support column 130 rises, and then drives support beam 140, flexible support 150 and photovoltaic module 160 to rise, and support beam 140 rose
Expansion link 123 is driven to move upwards in journey, expansion link 123 rises with water level and rises, and spacing column 120 rises with water level and stretches
Long, photovoltaic cells 10 are overall to be risen with water level rising, and each photovoltaic cells 10 rise with water level simultaneously and rise, and photovoltaic plant is whole
Body rises with water level and rises；When the water level descends, by the weight of photovoltaic module 160 and support beam 140 and support post 130 etc.
Power acts on, and floating drum 110 declines with water level decreasing, and drives support post 130 to decline, and then drives support beam 140 and photovoltaic
Assembly 160 declines, and support beam 140 is pressed downward expansion link 123 during declining, and so that expansion link 123 is moved downward, expansion link 123
Decline with water level decreasing, spacing column 120 shortens with water level decreasing, photovoltaic cells 10 are overall to be declined with water level decreasing,
Each photovoltaic cells 10 rise with water level simultaneously and rise, and photovoltaic plant is overall to be risen with water level rising.
Embodiment two
As shown in figure 5, in one embodiment, spacing column 120 includes column sleeve pipe 121, column 122, expansion link
123, column sleeve pipe 121 and column 122 are all partly fixed in underwater soil bearing layer 30, column sleeve pipe 121 offer many
Individual limbers 125, column 122 is arranged in column sleeve pipe 121；Connecting hole 1231, expansion link 123 are offered on expansion link 123
One end is stretched into column sleeve pipe 121 inner sleeve and is connected to inside column sleeve pipe 121, and column 122 stretches in connecting hole 1231,122 sets of column
It is connected to inside expansion link 123, the other end of expansion link 123 is stretched out the water surface 20 and is connected with support beam 140；Expansion link 123 is arranged on
Between column sleeve pipe 121 and column 122, expansion link 123 can rise with water level and rise, and decline with water level decreasing.
Specifically, in the present embodiment, limbers 125 can make the water in water body flow into column sleeve pipe when water level rises
In 121, the water level in column sleeve pipe 121 is risen with the water level of the water surface 20 simultaneously, and expansion link 123 is in floating drum 110 and support beam 140
Drive under, and with column sleeve pipe 121 water level rise and steadily rise；When the water level descends, the water in column sleeve pipe 121
Flowed out by limbers 125, flow in water body, the water level in column sleeve pipe 121 is declined with the water level of the water surface 20, expansion link simultaneously
123 steadily decline with the water level decreasing in column sleeve pipe 121 in the presence of photovoltaic plant entirety gravity, photovoltaic plant overall with
Water level decreasing steadily declines.
In the present embodiment, by the water inflow in water body when limbers 125 makes water level rise is being opened up on column sleeve pipe 121
In column sleeve pipe 121, when the water level descends, the water energy in column sleeve pipe 121 enough flows back in water body, makes in column sleeve pipe 121
