Construction scheme of floating photovoltaic project on water

The photovoltaic power station adopts floating bracket, which mainly uses floating body to float photovoltaic modules on the water surface to generate electricity.

Example of floating fishery light complementary

For the near shore of the inverter along the edge of the array placed as close as possible to the roadside channel, to facilitate late operation and maintenance. After the integral connection of the buoy is strengthened, the buoy, the connecting rod and the shore are connected in series by a movable hinge device, and the anchor rope is used to anchor the anchor piles.

For those far from the shore, the inverters can be placed on the independent pontoons, the inverters can be placed in the middle of the square array on the independent floating platform, and the buoyancy design of the pontoons and platforms can be done well, when the pontoon is fully connected, several steel plates can be used to cover the pontoon directly. The pontoon is filled with buffer material between the pontoon and the pontoon to reduce the influence of water surface movement on the pontoon platform. The pontoon platform is anchored down.

(1) the floating body platform is fixed to the underwater concrete anchor block by a spring-pulling fixing device, which is composed of special anti-corrosion natural fiber and metal elements. It is very firm and stable in tension. It is suitable for all kinds of water surface within 6m of water level difference. This scheme can keep the same level position and freeboard height all the time when the water level changes.

(2) the floating body connects the wharf to the bottom or the bank by means of the anchor chain through concrete anchors at a selected suitable location. The size of concrete anchor blocks depends on the water area or wind and wave environment, which is suitable for the water environment with little change of water level.

The floating PV project will inevitably lead to blisters on the PV equipment. Slocable has IP68 waterproof connectors and waterproof cables to help you

Construction scheme of inverter floating platform

The floating platform used in this project is a practical new type, simple structure, convenient site construction and good stability of the floating platform. The characteristics of this platform design are: the shell is welded by steel plate, the shell is filled with extruded polystyrene floating material, the outer circumference and the top of the shell are poured with reinforced concrete, and the outer circumference and the top of the shell are poured with reinforced concrete, to form a concrete floating platform. The shell is welded by steel plates and a stiffening beam is arranged to prevent the extrusion deformation in the course of concrete pouring; the inner wall of the shell is coated with anti-corrosion paint to meet the service life requirements under the corresponding environment; the outer wall of the shell is provided with plum-shaped anchorage steel bars, it is anchored into the concrete wall and the roof outside the steel plate, thus ensuring the integrity of the shell and the concrete enclosure of the floating platform, in order to prevent the floating platform from collision and damage in the process of transportation and hoisting, the corresponding hooks are arranged around the top plate of the floating platform, which also act as anchor ears when the floating platform is anchored.

1. First, steel plates and stiffening beams are welded to form a floating platform shell with the opening upward, the outer side of the shell is welded and anchored with steel bars, and the inner side of the shell is coated with anti-corrosion coating after anti-corrosion treatment, xPS extruded polystyrene is filled by internal lamination bonding and then the shell is turned upside down to make the opening face down. The roof on the outside of the shell is welded and anchored with reinforcing bars.

2. After the shell is made, the shells are placed in position and fixed reliably, and the steel mesh of the floating platform wall plate and the roof plate is tied; the angle steel protecting angle of the fixed circumferential ring, the hook and the embedded parts of the plate roof are fixed reliably, a formwork for the concrete outer wall plate is arranged on the circumference circle and is fixed.

3. Pour the concrete on the side wall and the roof of the floating platform, vibrate fully, and maintain the concrete. After the concrete strength is 100% , remove the outer formwork, the floating platform can be transported, hoisted to the corresponding position and fixed with underwater anchor rope around the connection point; the upper railing of the platform can be installed after equipment is in place.

Construction scheme of photovoltaic bracket pontoon

Main construction methods:

1, construction preparation: level the site, repair access road, machinery, materials into the field.

2, the production of photovoltaic bracket: Photovoltaic Bracket factory processing site assembly method to install, try to avoid the site cutting, welding process.

3,Assembly of the pontoon and support: the pontoon can be assembled into small units on the shore, and then the small units can be connected locally in the water to form a large unit; after the support and the pontoon are made and installed, they are fixed on the pontoon on the shore to form a network support system, when all the supports and components of the small unit are installed, they are placed on the steel rails on the shore, pulled into the water by the engineering ship in the water, and the support system is pulled to the designated position by the power ship after all the supports are in the water, the prestressed pipe pile is anchored by anticorrosive steel wire rope.

4,In the process of environmental protection, the river course should not be polluted by production oil, and the river course should not be polluted by cofferdam filling and demolishing.
