Abstract

The invention relates to the technical field of photovoltaic power generation, and discloses an ice-pushing upward-sliding snow-accumulation-preventing type water surface photovoltaic floating systemsuitable for alpine regions. The system comprises a photovoltaic module and a plurality of module floating body groups, each module floating body group comprises a plurality of module floating body units arranged side by side, and the photovoltaic module is mounted on the module floating body units through a bracket system. A plurality of channel floating bodies are arranged between every two adjacent rows of assembly floating body groups, each channel floating body is located in the center of the corresponding four adjacent assembly floating body units, and the four corners of each channel floating body are connected with the corners of the corresponding four adjacent assembly floating body units respectively. The two ends, facing the channel floating body, of each assembly floating bodyunit extend outwards to the outer side of the projection of the photovoltaic assembly to form aisles. The ice-pushing upward-sliding snow-accumulation-preventing type water surface photovoltaic floating system suitable for the alpine regions can achieve the functions of resisting freezing loads, preventing snow accumulation coverage and increasing the shadow distance between assemblies, and has the advantages of being simple in structure, easy to achieve, convenient to operate and maintain, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to an ice push-up and anti-snow type water surface photovoltaic floating system suitable for alpine regions. Background technique [0002] In Northeast China, Inner Mongolia and other high-latitude cold regions, land resources are scarce and mountainous conditions are harsh, and the development of ground-mounted photovoltaic power stations is limited. The construction of water-surface photovoltaic power stations in reservoirs in these regions can make full use of local solar energy resources without crowding out precious local pasture resources. It can also provide economical and convenient power resources for nearby herdsmen, and the economic and social benefits are huge. [0003] However, due to the low temperature and long freezing time in the severe cold areas of high latitudes, higher requirements are put forward for the anti-freezing of floating systems. ...

Problems solved by technology

[0004] At present, most of the water surface photovoltaic floating systems proposed at home and abroad only focus on their use in mid- and low-latitude regions, without special consideration of the extreme environments in high-latitude severe cold regions, and some floating systems only focus on high-latitude severe cold regions. Local influencing factors, not comprehensively considering all factors

[0005] Chinese patent (publication date: September 20, 2019, publication number: CN209419535U) discloses a floating power generation system and its supporting array, which uses a beam system to connect the floating bodies to form an array supporting photovoltaic modules, which only has strong anti-corrosion Surge performance, does not have the ability to be used in high latitude cold regions

[0006] Chinese patent (publication date: July 30, 2019, publication number: CN209176870U) discloses a floating floating body and floating body array. Effects of snow and shadows on floating structures

However, the floating system connected to the flat iron can only release part of the frost heave force between the floating bodies, and it is difficult to release the frost heaving force around the floating body, and it is difficult to protect the weaker floating bodies in the system; secondly, the structure uses lifting cylinders to adjust the photovoltaic Module inclination angle, although the inclination angle of photovoltaic modules can be adjusted, but the cost investment is relatively large, and the distance between the front and rear photovoltaic modules has not been adjusted after the inclination angle of photovoltaic modules is increased, which may cause photovoltaic modules to block and affect power generation

[0009] Due to the above-mentioned technical problems in the floating system of the existing floating water surface photovoltaic power station, it is difficult to promote the use of water surface photovoltaic power station in high latitude and severe cold areas, wasting idle water resources and hindering the development of water surface photovoltaic in these areas
