[0016] Compared with the prior art, the present invention provides a water photovoltaic installation device, which has the following beneficial effects:

[0017] 1. This kind of water photovoltaic installation equipment, by setting extension rails, fixed pulleys, cables, knots and wire clamps, installs multiple extension rails on the tail of the main rail in turn, extends the combined rail, pulls the cables, and converts the pulling force into thrust of the knot on the inner wall of the wire clamp, thereby pushing the frame to move toward the main rail, causing all photovoltaic panels to fit tightly and move in the direction of the main rail until they fit the inner wall of the main rail, and fixes the end of the cable away from the knot on the water bank, thus completing the installation and fixation of the entire photovoltaic panel array, and the length of the combined rail can be freely adjusted by adding or reducing extension rails, so that the installation position of the main rail on the water surface can be freely adjusted, and the number of photovoltaic panels to be installed can also be freely arranged according to needs, and after the main rail and the extension rail are fixed, the staff can complete the water installation of the photovoltaic panels on the shore, and the operation method is convenient and has a wide range of applicability.

[0018] 2. This kind of water photovoltaic installation equipment is equipped with a float, a threaded column and a threaded sleeve. The float floats on the water surface, provides a pulling force to resist gravity for the extension rail, and reduces the risk of the entire device sinking. By rotating the threaded column, the threaded column, the suspension rope and the float can be removed from the threaded sleeve, which is convenient for replacing or maintaining the float that has leaks.

[0019] 3. This kind of water photovoltaic installation equipment is equipped with plug blocks, slots, pins, springs and pull handles. The extension rails or the extension rails and the main rails are connected through the plug blocks and slots. When connecting, the pin is pulled up by the pull handle, the spring is stretched, the inner cavity of the slot is vacated, and the plug block is inserted into the cavity of the slot. At this time, the pull handle is released, and the spring drives the pin downward to insert into the pin hole of the plug block, so that the plug block and the slot can be quickly connected in a simple way, and it is convenient for the subsequent installation of multiple extension rails.

[0020] 4. This kind of water photovoltaic installation equipment is equipped with an upper airbag, a bellows and a lower airbag. The buoyancy component composed of the upper airbag, the bellows and the lower airbag floats on the water surface and forms a support at the bottom of the bottom plate. The bellows can be extended and retracted, so that the volume of the inner cavity composed of the upper airbag, the bellows and the lower airbag can be changed, which can adapt to the changes in the air pressure in the inner cavity, avoid the upper and lower airbags from being damaged due to excessive deformation caused by pressure changes, and extend the service life of the device.

[0021] 5. This kind of water photovoltaic installation equipment is equipped with a blower, a one-way air inlet valve, a one-way exhaust valve, a push rod motor, a piston cylinder, a piston rod and a piston. When inflating, the one-way air inlet valve is turned on, and the blower sends air into the upper air bag through the first intake pipe and the second intake pipe. After the barometer detects that the air pressure reaches the standard, the signal is fed back to the controller to control the blower to stop supplying air, and the one-way air inlet valve is closed at the same time. Affected by temperature, atmosphere, etc., when the barometer detects that the air pressure in the upper air bag exceeds the standard, the one-way exhaust valve is turned on, and the air inside the lower air bag is discharged through the low exhaust pipe and the high exhaust pipe. When the air pressure reaches the standard again, the controller controls the one-way exhaust valve to close. When the barometer detects that the air pressure in the upper air bag is slightly deficient and cannot be accurately supplemented by the blower, the controller controls the push rod motor to pull down the pressure plate, and the piston rod pushes the piston into the piston cylinder, and presses the air inside the piston cylinder into the upper air bag, so as to achieve the purpose of supplementing the air pressure.

When inflating, the one-way air inlet valve 27 is turned on, and the blower 29 sends airflow into the upper airbag 5 through the first air inlet pipe 26 and the second air inlet pipe 28. After the barometer 32 detects that the air pressure reaches the standard, the signal is fed back to the controller. The blower 29 is controlled to stop supplying air, and the one-way air inlet valve 27 is closed at the same time.
