Embodiment 1
[0038] Such as figure 1 , figure 2 As shown, the structural diagram of the heat collector and its supporting device in one embodiment of the solar thermal power generation system of the present invention is given.
[0039] In practical application, the bracket 13 is fixed on the ground, and the beam 6 is installed on the bracket 13, so that one or two arms protrude from the bracket to the surrounding space to form a cantilever beam. This embodiment shows the situation that there are two arms, and those skilled in the art can easily understand that there may be only one arm depending on the installed capacity of the system and other parameters.
[0040] figure 2 A sectional view of the above-mentioned heat collector support device is shown to illustrate the working principle of the support device. An engaging device 12 is provided on the heat collector 5 so as to be connected and fixed with the beam 6, and a direction-adjustable windshield 16 is installed on the side of th...
Embodiment 2
[0046] Such as image 3 As shown, the second embodiment of the solar thermal power generation system of the present invention is given. In this embodiment, the crossbeam 6 adopts the form of simply supported beam and is supported on the brackets 13 at both ends. By installing on the crossbeam 6 The corresponding driving device 17 can easily realize the longitudinal movement of the heat collector 5 along the beam 6, so that when the position of the beam 6 does not move, the position of the heat collector 5 in space can be adjusted longitudinally along the beam 6 to follow the mirror field. The point with the highest light collection efficiency.
Embodiment 3
[0048] Such as Figure 4As shown, the third embodiment of the solar thermal power generation system of the present invention is provided. In this embodiment, the support 13 adopts the form of an upright column, and the beam 6 adopts the form of a cantilever beam, which can be driven by the driving device 17. Rotate and move up and down around the bracket 13, the heat collector 5 is suspended and installed on the beam 6, and can move up and down relative to the beam under the action of the hoist, and can stay in any position that can be rotated or moved to absorb heat; the solar light The pipeline system of the thermal power generation system is provided with a device that can turn the pipeline. This embodiment adopts the pipeline joint 23, and it can also be realized by using the bellows according to the site conditions.
