Description
Technical Field
The invention relates to the field of photovoltaic power generation, in particular to a trinity coupling plug-in type water surface photovoltaic power generation unit and a power generation system thereof, wherein the trinity coupling plug-in type water surface photovoltaic power generation unit is simple in structure, convenient to install and low in processing difficulty.
Background
The photovoltaic power generation system is a power generation system which is formed by utilizing solar energy and adopting special materials such as a crystalline silicon plate, an inverter and other electronic elements, is connected with a power grid and transmits power to the power grid. The photovoltaic power station is a green electric power development energy project with the highest national encouragement intensity at present, and makes an important contribution to the construction of a low-carbon society. However, land photovoltaic power stations occupy large area, land resources cannot be reasonably allocated, and China has numerous idle water surface resources such as reservoirs, lakes, subsidence areas and the like, and the construction of water photovoltaic by utilizing water surface space is the optimal utilization of the resources, so that the land resources can be reasonably utilized, the generated energy can be improved, the water environment can be protected, and floating dust can be reduced.
The water surface floating type photovoltaic power station utilizes floats to support the photovoltaic module for a certain angle and then floats on the water surface to realize the power generation function. Because the environment where the water surface floating photovoltaic power station is located is moist, structural components are easy to corrode, and in order to ensure the corrosion resistance and the service life of floaters, a high-density polyethylene floating body is generally adopted to provide buoyancy for the water surface photovoltaic power station. The main production modes of the waterborne floating body comprise blow molding and rotational molding, but the rotational molding technology has low production efficiency and poor sealing property, and the floating body can keep buoyancy by filling foam, so that the application is less; the production efficiency and the product performance of the blow molding product are greatly related to the structural form, and how to simplify the structural form under the condition of guaranteeing the function of the floating body is a problem to be solved.
The photovoltaic power generation system not only comprises a solar cell module, but also comprises equipment such as a combiner box, an inverter, a cable trough and the like. The direct current generated by the solar cell module is transmitted to the string type inverter through a cable, and the inverted low-voltage alternating current is transmitted to the junction box through the cable, and is transmitted to the transformer through the cable after junction. In order to reduce the consumption of cables and improve the economy of the photovoltaic power station, equipment such as an inverter, a combiner box, a cable trough and the like needs to be installed and fixed on a water surface floating body. Unlike photovoltaic modules, electrical devices such as string inverters and combiner boxes are installed on the water surface with certain special requirements, such as off-water height, installation angle and the like. At present, most existing floating body design forms only consider the fixed installation of the photovoltaic module, and special consideration is not made on the fixation of electrical equipment such as a combiner box, a string inverter, a cable trough and the like on the floating body. In practical application, such floating bodies often fixedly mount electric equipment such as an inverter, a combiner box and the like through a floating body photovoltaic module mounting structure, so that not only are the electric equipment mounting requirements not met, but also the mechanical properties are not met. For water cable laying, the current partial water surface photovoltaic power generation system designs a special water cable channel floating body, but the special floating body needs to be provided with an additional die, so that the construction cost of a power station is increased, and the photovoltaic power station is not beneficial to realizing low-price surfing.
At present, a plurality of water surface photovoltaic power generation system design schemes are proposed at home and abroad, so that the problems of the water surface photovoltaic power generation system design schemes are solved, but the design schemes also have a plurality of problems from the aspects of the reasonability and the universality of the floating body structure. As CN201520671619.5 discloses a carrier for photovoltaic modules on water, the support tables at two ends of the floating body have a certain height difference for supporting the photovoltaic modules at a certain angle, and the lower part of the support table has at least one opening for bearing the photovoltaic modules, and can be matched with the installation connection support piece for fixing the photovoltaic modules. However, the high-level support table, the low-level support table and the main floating body are integrally formed, so that the high-level support table can be raised higher when the inclination angle of the assembly is larger, and the local wall thickness can be too thin in the blowing process, so that potential safety hazards are generated; and the openings at the high-position and low-position support tables of the floating body are concave buckles, so that the product is difficult to demold, and the product can be damaged or cracked due to strong demolding. CN201520606080.5 discloses a floating body of a photovoltaic power station floating on water, and at least one group of opposite grooves are arranged on two sides of the floating body. Similar to the above patent, the design scheme of the patent also has the conditions of uneven wall thickness of blow molding and strong back-off demolding in the production process, and generates hidden quality hazards. CN201520911191.7 discloses a water surface light Fu Futi, two ends of the floating body are provided with embedded connection plates with different heights, and the embedded connection plates are used for installing a photovoltaic module. The design scheme can also appear the uneven condition of blow molding wall thickness in the production process to connecting plate length is longer when the inclination is great, the problem of intensity deficiency appears. WO2012/139998A2, CN201620133888.0, CN201520618986.9, CN201510610856.5 and other patents disclose a water surface photovoltaic floating body, and the photovoltaic component is fixed by utilizing parts such as guide rails, bolts, clamping grooves and the like of different materials preset at the two ends of the upper surface, so that the problem of strong demolding possibly occurring is avoided, the surface structure is optimized, and the uneven wall thickness of blow molding is prevented. However, the preset part introduces a new problem, firstly, the preset part needs to be manufactured independently, and the preset part needs to be placed in a mould in advance in the blowing process, so that the production period of the product can be increased, and the production efficiency of the product can be reduced; and secondly, the preset part and the floating body are formed in a non-integrated manner, the connection tightness between the preset part and the floating body is reduced, the service life of a product is influenced, and particularly when the preset part is made of a metal material, the physical property difference between the preset part and the floating body is large, and the inconsistency of the change of the two materials under the environmental condition can lead to the failure of the preset part. CN201620418220.0 discloses a multi-ear type floating body on water, which achieves stronger connection stability by increasing the number of connecting ears of the floating body; the photovoltaic module is supported and clamped by using a metal bracket. The patent is simple and convenient to install, the connection between floating bodies is firm, but the following problems exist: the left side and the right side of the main floating body of the photovoltaic module support are respectively connected to different pavement floating bodies, and the different stress of the two pavement floating bodies can cause the asynchronous left and right deformation of the main floating body, so that the photovoltaic module is damaged; the floating body is too many in variety, the die sinking cost is high, and the production efficiency can be reduced; no fixed support exists between the long metal supports of the photovoltaic module, and the deformation of the two supports is asynchronous easily caused, so that the photovoltaic module is damaged. None of the above patents considers the versatility of the water surface mounting and fixing of electrical devices such as string inverters, combiner boxes, etc., nor mentions the water cabling scheme.
