Embodiment Construction
[0014] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.
[0015] Such as figure 1 and figure 2 As shown, the present invention is a multi-position height-adjustable line-focus reflective support device, which includes a main shaft 1 connected with a tracking system. The main shaft 1 is a metal circular tube and plays the role of bearing and rotating shaft. The main shaft 1 is horizontally set under the supporting beam 2. The supporting beam 2 is composed of a plurality of channel steels whose length is equal to the width of the reflector installed in parallel on the steel pipe. It has two functions of structural support and structural balance. Each supporting beam 2 is equally spaced Five vertical adjustable fulcrums 3 are provided.
[0016] Such as image 3 As shown, the adjustable fulcrum 3 uses channel steel as the basic structure, with a long hole 7 on the side, a fine-tuning screw 6 installed ...

The invention relates to a multi-position height adjustable line focusing reflective support device, which comprises a main shaft connected with a tracking system, wherein the main shaft is arranged below a support cross beam horizontally; and more than two vertical adjustable fulcra are arranged on the support cross beam at equal intervals and are connected with a reflecting mirror base in a movable mode. On the basis of the principle of mechanical cold deformation, the radian of a plane mirror is regulated by utilizing the support device to manufacture a micro-arc mirror surface quickly with low cost; and compared with the conventional technology of machining a cambered surface mirror by hot bending, the multi-position height adjustable line focusing reflective support device has the advantages that: due to the adoption of the ordinary plane mirror, the machining cost is reduced substantially; and for a micro-arc mirror, the complexity of a machining process is reduced greatly, and the arc-shaped accuracy of the reflecting mirror is improved, so the condensing efficiency of the line focusing reflecting mirror can be improved substantially, and the installation debugging cost of a system can be reduced.
Description
technical field [0001] The invention belongs to the field of solar thermal power generation, and in particular relates to a multi-position height-adjustable line-focusing reflection support device. Background technique [0002] Solar thermal power generation technology uses concentrators to gather solar energy and convert it into heat energy, and then generate high-temperature and high-pressure steam to drive steam turbines to generate electricity. [0003] Line-focusing solar concentrating thermal power generation technology is a common form of solar thermal power generation at present. The mirror field composed of multi-faceted mirrors gathers the solar energy into a linear spot, and then uses the receiver to convert the light energy into heat energy. Heat energy is absorbed and transferred to the heat exchanger. In the heat exchanger, the heat of the heat transfer fluid is used to heat the water to generate water vapor, and then use the water vapor to drive the steam tur...
