Description

Integrated assembled water surface photovoltaic power generation system and its installation method

technical field

The invention relates to the field of photovoltaic power generation, and specifically refers to an integrated assembled water surface photovoltaic power generation system with simple structure, convenient installation, stable structure and low cost and an installation method thereof.

Background technique

As an ideal clean energy for human beings, solar energy has made important contributions to building a low-carbon society. With the continuous maturity of photovoltaic technology, photovoltaic power generation has gradually become the main force of new energy power generation. However, due to the large area occupied by photovoltaic power stations, land resources cannot be rationally allocated. Therefore, the use of water surface space to build floating photovoltaics is an optimal use of resources. It can not only make rational use of land resources, increase power generation, but also protect the water environment and reduce floating dust.

The surface floating photovoltaic power station uses floating tubes, floating tanks, etc. as floating bodies, and uses itself as a support or builds a support on the floating body to support the photovoltaic modules at a certain angle to achieve power generation. For the water surface photovoltaic power generation system that combines the floating body and the bracket, since the bracket is located near the water surface, it is easy to cause corrosion damage to the bracket, so the requirements for the bracket material are relatively high; for the full floating body surface photovoltaic power generation system, the floating body not only provides buoyancy, but also can be used as a photovoltaic power generation system. The module support simplifies the system structure and installation procedure, and also improves the corrosion resistance of the photovoltaic power generation system. At present, most of the full-floating surface floating photovoltaic power generation system schemes use split floating floating bodies, including supporting main floating bodies and walkway auxiliary floating bodies, which increases the workload of connection between floating bodies, resulting in increased labor costs and time costs.

At present, there are already many patents on the floating body of the floating photovoltaic power station on the water surface, but most of them have not solved the above-mentioned problems. For example, CN105119558A discloses a modular aquatic photovoltaic array, which uses a connection mechanism installed on a floating body to support photovoltaic modules, but this patent does not consider the maintenance channel of photovoltaic modules, which is not conducive to the later maintenance of power stations; Patents such as CN205105144U, CN204836054U, US2014224165A1, and CN105186968A are similar to the water surface photovoltaic power generation systems. They all combine the floating body and the bracket to form an integrated photovoltaic module support structure, and design pedestrian passages for easy maintenance. However, the first component of these photovoltaic floating bodies supports the floating body. The volume is large and the manufacturing cost is high; the inclination angle of the design of the floating body is low, which is difficult to apply to high-dimensional areas; on average, each photovoltaic module needs to install a large number of parts, the installation process is complicated, and the labor cost is high; the floating body does not consider the function of placing cables. During the use process, a large number of floating bodies need to be laid as cable channels. On average, each photovoltaic module occupies more floating body materials, and the cost is relatively high; CN2016103175562 discloses a floating body for an L-shaped water surface photovoltaic power generation system. This floating bucket uses left and right to support photovoltaic modules. form, and use steel and steel pipes to form an array, which enhances the overall stability of the floating system. However, in this patent, the position of the steel is near the water surface, which is easy to cause corrosion damage to the steel structure, and the aisle of the floating body structure is thin and the interval is relatively large, so it is not easy to construct and maintain; A floating photovoltaic support system on the water surface. Two floating tanks are used to form a support unit, and the middle is connected by a connecting piece. The photovoltaic module support parts can be installed on both sides of the floating tank, and the two sides of the photovoltaic module are respectively installed on the two floating tanks. Although the idea put forward by this patent group can save the special support floating body for photovoltaic modules and increase the backwater area of photovoltaic panels, the description of the system, components or installation method in the patent is too abstract to consider engineering solutions such as its stability, cost and installation volume. , does not have engineering operability; CN105129041A discloses a modular twin-hull integrated floating device for a variable-inclination full-water photovoltaic power station, including a cuboid channel and a component support slope, and realizes an easily expandable modular water surface floating power generation device. However, in this patent, the structure of the floating body is large, the transportation cost is high, and the average installation quantity of the components is large, which increases the construction workload and is not conducive to popularization and utilization.

At present, the construction cost of photovoltaic power stations on water surfaces is relatively high, and installation on water is more difficult than on the ground. Therefore, how to simplify the structure and connection of floating bodies, reduce the cost of floating bodies, components and installation, and improve the maintainability of photovoltaic power stations is the sustainable development of floating photovoltaic power stations on water. issues that need to be considered and resolved.

Buoyancy calculation:

In this example, a polysilicon module with a power of 260Wp and a size of 992mm×1650mm is used, and its carrying capacity is calculated as follows with 88 photovoltaic modules as a unit:

The total load of the surface photovoltaic power generation system:

Photovoltaic module: 20Kg/block × 88 = 1760kg;

Floating body self-weight: main floating body: 14.87Kg/block×104 blocks=1546.48kg; connectors: 0.36kg/block×208 blocks=74.88kg; walkway board: 10kg/block×16 blocks=160kg;

Installation and maintenance personnel: 8 persons × 75Kg/person = 600Kg.

Considering the safety factor of 2.0, the total load is about 8282.72kg,

The total buoyancy of the surface photovoltaic power generation system:

According to the buoyancy formula, the buoyancy that the main floating body can provide is 197kg/block, then the total buoyancy is: 197kg/block×104 blocks=20492.16kg.

Therefore, this embodiment can fully guarantee the buoyancy requirement of the water surface photovoltaic power generation system.

Workload calculation for installation parts:

In this embodiment, 88 photovoltaic modules are used as a unit to calculate the number of installation parts as follows:

Main floating body connecting pins: 192 pieces

Connection supports: 208 pieces

The total number of installation parts is 400 pieces, and the average workload of floating body and module installation parts is about 4.5 pieces per photovoltaic module.

Compared with the patent US2014224165A1, the workload per installation of photovoltaic modules has decreased by about 11 pieces. Therefore, this embodiment can reduce the workload of the installation parts and save labor costs.

Float cost calculation:

In this embodiment, 88 photovoltaic modules are used as a unit to calculate the floating body material required for a single photovoltaic module. The values of the wall thickness of the floating body and the height of the main floating body are similar to those of patents US2014224165A1 and CN105186968A, respectively:

Wall thickness of floating body: 5mm on the upper surface and 3mm on the rest

Float height: 200mm

Materials required for a single float:

Main floating body: 14.87kg/piece, connecting support: 0.36kg/piece

The floating body material required for each photovoltaic system unit is: 104×14.87kg/unit+208×0.36kg/unit=1622.0kg

The average material required for a single photovoltaic module is: 1622.0kg/88＝18.4kg

Compared with patents US2014224165A1 and CN105186968A, a single photovoltaic module saves about 2.4kg of materials. Therefore, this embodiment can reduce the consumption of materials and save costs.
