Description

Direct current cable crossing laying structure between different arrays of water photovoltaic project Technical Field The utility model relates to the technical field of cable laying, in particular to a crossing laying structure of direct current cables among different arrays of a water photovoltaic project. Background Along with the common larger installed capacity of new energy photovoltaic fields, especially water surface photovoltaic, in order to meet the construction requirement of 'fishing light complementation', the array spacing between different groups of photovoltaic strings is larger, and conventionally, a hot dip galvanized steel pipe is adopted to lay a direct current cable so as to meet the requirements of large span, large cross section through pipe area and larger rigidity support, the diameter and the wall thickness of the steel pipe wall have to be increased, so that engineering material waste is caused, and engineering construction cost is increased. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a crossing laying structure of direct current cables among different arrays of a water photovoltaic project, which can meet the laying requirement of large-span cables among strings, greatly reduce the construction cost and improve the construction efficiency, and aims to solve the technical problems of insufficient rigidity, higher cost and high construction difficulty of the traditional galvanized steel pipe. In order to achieve the above purpose, the present utility model provides the following technical solutions: The direct current cable crossing laying structure comprises prefabricated pipe piles, pipe hoops are respectively arranged at equal height positions of adjacent prefabricated pipe piles, a steel wire rope is fixed between the two pipe hoops, and a cable protection pipe is fixed on the steel wire rope; the pipe hoop is connected with a pull rod, the pull rod is connected with a fastener, and the fastener is connected with a steel wire rope. In the crossing laying structure of the direct current cables among different arrays of the above-water photovoltaic project, the steel wire rope and the cable protection tube are fixed through a plurality of tube clamps. In the crossing laying construction of the direct current cables among different arrays of the above-mentioned water photovoltaic project, the interval between the adjacent pipe clamps is smaller than 50cm. In the crossing laying structure of the direct current cables among different arrays of the above-mentioned water photovoltaic project, the direct current cable also comprises a direct current cable, and the direct current cable between the two prefabricated pipe piles is arranged in the cable protection pipe in a penetrating way. In the crossing laying structure of the direct current cables among different arrays of the above-water photovoltaic project, the pipe hoop comprises two half hoops, two ends of the two half hoops are respectively connected through bolts, one end of the pull rod is hooked and fixed on the bolts, and the other end of the pull rod is hinged and fixed through the fastener after penetrating through the steel wire rope. The beneficial effects are that: The traditional scheme adopts measures such as the galvanized steel pipe must increase wall thickness in order to satisfy large-span rigidity requirement, can have the material to consume more, construction cost is higher, the great defect of construction degree of difficulty. In contrast, the utility model only comprises common materials of construction sites such as pipe hoops, steel wire ropes, pull rods, fasteners, pipe clamps, cable protection pipes and the like, has simple assembly structure and simple assembly process, can effectively reduce the construction difficulty and the engineering cost, and is convenient to detach and wide in application range if parts need to be replaced in the later use stage. Therefore, the utility model can optimize the engineering quantity and improve the construction efficiency, and the scheme of the utility model has no substantial influence on the cable laying in the implementation process and does not influence the normal use of the direct current cable.
