Embodiment Construction
[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0040] A hoisting and positioning method for a trough solar heat collector, comprising:
[0041] S1. Set up the shoulder pole
[0042]The shoulder pole is lifted on the boom of the crane. The length of the pole is consistent with the length of the trough solar collector. By adjusting the length of multiple lifting ropes connecting the pole, the pole is in a horizontal state after lifting.
[0043] A connecting rope is arranged at both ends of the shoulder pole. One end of the connecting rope is provided with a lobster clasp, and the other end is provided with a buckle ring. The first and last ends of the connecting rope are connected through the cooperation of the lobster clasp and the buckle ring (also can be connected in other ways). Pass the connecting rope through the hoisting holes 7 at both ends of the trough solar collector, and connect the connecting...

The invention relates to the technical field of trough solar thermal collector construction and installation, in particular to a hoisting and positioning method for trough solar thermal collectors. The hoisting and positioning method for the trough solar thermal collectors comprises the following steps of: S1: hoisting the first two trough solar thermal collectors; S2: hoisting the rest trough solar thermal collectors; and S3: regulating and connecting with the trough solar thermal collectors. When the trough solar thermal collectors are hoisted, all trough solar thermal collectors are subjected to central position positioning through the cooperation of positioning shafts and positioning holes, and the orientations of the trough solar thermal collectors are regulated. When telemeter rods suspended on symmetrical structure positions on the left cantilever and the right cantilever of each trough solar thermal collector have the same indicated reading obtained by aiming at a level gage, aresult shows that the forward direction of the trough solar thermal collector just faces upwards. According to the hoisting and positioning method, after all trough solar thermal collectors are regulated can be conveniently regulated to realize a purpose that the forward directions face upwards, adjacent trough solar thermal collectors are fixedly connected.
Description
technical field [0001] The invention relates to the technical field of construction and installation of trough solar heat collectors, in particular to a hoisting and positioning method for trough solar heat collectors. Background technique [0002] Sunlight incident on the earth's surface through the atmosphere will produce radiant energy with low heat flux density, and the economic benefits of direct use are low. Higher economic benefit. [0003] The trough solar collector uses the trough parabolic concentrating reflector to gather the solar radiation energy with high heat flux density to realize the light-to-heat conversion. When used in a system, multiple trough solar collectors form an array that collectively track the sun to collect heat. Since solar thermal power generation is in the early stage of development in China, there is a lack of experience in the construction of trough solar thermal power generation units in China. [0004] Such as figure 1 and figure 2...
