The offshore photovoltaic power station includes a pile foundation, a photovoltaic support arranged on the pile foundation, and a photovoltaic panel arranged on the photovoltaic support. The offshore photovoltaic power station is usually located in a region far from the shore, and economy is a key factor restricting large-scale development of offshore photovoltaic power stations.

[0025] In the related art, the existing operation and maintenance mode of the offshore photovoltaic power station relies on ships, which is not only costly, but also limited by weather conditions, low in efficiency and poor in safety. Chinese patent CN117922770A discloses a kind of offshore photovoltaic power generation platform and photovoltaic system, which includes a network component, a plurality of photovoltaic bearing floats and a plurality of operation and maintenance floats, the photovoltaic bearing float is detachably connected with the network component, and the operation and maintenance float is arranged above and / or below the first hole of the network component to form an operation and maintenance channel,

[0026] However, the offshore photovoltaic power station is usually located in a region far from the shore, which is difficult to operate and maintain itself. In addition, the photovoltaic support is often designed as a large-span structure to reduce the number of pile foundations and construction costs. However, the photovoltaic power station suitable for large-span supports has a large number of photovoltaic panels and complex lines. The operation and maintenance mode relying on existing ships or the mode of setting the above operation and maintenance floats not only requires a large number of ships or operation and maintenance floats, but also is limited by weather conditions, low in efficiency and poor in safety. The setting of multiple operation and maintenance floats not only increases the cost, but also increases the load of the photovoltaic support, greatly increasing the operation and maintenance cost and difficulty.

[0027] As shown in Figures 1 to 5 , in order to achieve the above purpose, the utility model provides a kind of operation and maintenance channel 100 for offshore photovoltaic large-span support, including operation and maintenance mechanism 10 and support mechanism 30, as shown in Figures 1 to 2 , operation and maintenance mechanism 10 includes operation and maintenance framework 11 arranged on the side of photovoltaic support 63 and pass-through framework 12 arranged in photovoltaic support 63, the top of operation and maintenance framework 11 is connected with the top of photovoltaic support 63, and the middle part is connected with photovoltaic support 63 through support mechanism 30, so that the plane where photovoltaic panel 65 is laid on photovoltaic support 63 is arranged at an angle with the vertical plane of operation and maintenance framework 11, as shown in Figure 3 .

[0028] The utility model discloses a maintenance channel 100 for offshore photovoltaic large span support includes maintenance mechanism 10 and support mechanism 30, and maintenance mechanism 10 includes the side maintenance framework 11 of being arranged at photovoltaic support 63 and the passable framework 12 of being arranged at the inside of photovoltaic support 63, and the top of maintenance framework 11 is connected with the top of photovoltaic support 63, and the middle part is connected photovoltaic support 63 through support mechanism 30, makes the plane of photovoltaic panel 65 that is obliquely laid on photovoltaic support 63 and the vertical vertical plane of maintenance framework 11 is set up with the angle of setting. The wiring and electrical equipment of photovoltaic panel 65 are concentrated to maintenance framework 11 can orderly arrange the circuit, and maintenance framework 11 is connected to photovoltaic support 63 and eliminates the oblique design angle of photovoltaic support 63 through support mechanism 30, so that personnel can walk steadily on maintenance framework 11 and can reach maintenance framework 11 quickly through passable framework 12, to maintain and overhaul the wiring and electrical equipment through the channel, need not set up multiple interval maintenance floating body, reduce the operation and maintenance cost and operation and maintenance difficulty, reduce the transportation time of personnel and equipment, significantly improve the operation and maintenance efficiency.
