Megawatt tower type photo-thermal power generation heat collector mounting method and mounting system device

Abstract

The invention discloses a megawatt tower type photo-thermal power generation heat collector mounting method and mounting system device. The method is characterized in that at first, a heat absorptiontower is built on the ground at a tower type photo-thermal power generation heat collector mounting position, and according to the size of the tower type photo-thermal power generation heat collector,an internal space for tower type photo-thermal power generation heat collector hoisting is reserved in the heat absorption tower; then, the tower type photo-thermal power generation heat collector isintegrally assembled on the ground; the assembled tower type photo-thermal power generation heat collector integrally slides to the center in the heat absorption tower from an assembly site by sliding devices through a sliding channel; and finally, the megawatt tower type photo-thermal power generation heat collector is integrally hoisted from the bottom of the heat absorption tower to the top ofthe heat absorption tower by using gantries and a hydraulic crane at the top of the heat absorption tower, and integrally mounted by using a support frame. According to the method, the megawatt tower-type photo-thermal power generation heat collector is assembled on the ground at first, and is integrally hoisted to the tower top from the interior of the heat absorption tower so that the construction period can be effectively shortened, a large amount of aloft work can be reduced, and the safety construction can be greatly guaranteed.

Description

technical field [0001] The present invention relates to a hoisting method and a hoisting device for a tower-type photothermal power generation system, in particular to a hoisting safety control method and device for a megawatt-level tower-type photothermal power generation collector; The safety control method and device for hoisting thermal power collectors can effectively prevent failures of megawatt-level tower-type photothermal power collectors during hoisting; they belong to the technical field of hoisting operations for heavy objects. Background technique [0002] Solar thermal power generation refers to the use of large-scale arrays of parabolic or dish mirrors to collect solar heat, provide steam through heat exchange devices, and combine traditional turbogenerator technology to achieve the purpose of power generation. The use of solar thermal power generation technology avoids the expensive silicon crystal photoelectric conversion process, which can greatly reduce th...

[0008]3. The patent number is CN201620778657.5, a utility model patent named "Integral hoisting sling for solar thermal power generation collector module". The overall hoisting sling for the power generation collector module solves the technical problem of large size and difficult hoisting of the collector module

[0009]Through the analysis of the above patent documents, we found that these patents all involve hoisting, and there are also studies on the overall hoisting of solar-thermal power generation collector modules, and it is also proposed Some improved technical solutions have been proposed, but there are still some problems in these technical solutions, and there are still some practical problems of how to solve the overweight of the collector during the hoisting process of the tower solar thermal power collector, and how to carry out the overall hoisting. However, many unexpected problems and faults still appear in practical applications, so it is still necessary to do further research on this
