Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of heliostat auxiliary equipment in photo-thermal power generation, in particular to a spherical leveling support. BACKGROUND

[0002] The current global faces extremely serious energy and environmental problems, and solar thermal power generation is one of the key technologies to solve the problem. The basic principle of solar thermal power generation is that a large number of reflectors or condensers focus the solar radiation around the power station on the heat collection area, the heat collection area heats the working medium to absorb the solar radiation to generate high-temperature steam, drives the steam turbine generator set to generate electricity, thereby converting solar energy into electrical energy. Tower type molten salt photo-thermal power generation is one of the technical routes of solar thermal power generation, and the power station is composed of three units: solar heat collection, heat storage unit and heat power conversion power generation unit. The former two mainly include condensation, heat absorption, heat storage and heat exchange; the latter includes heat engine, heat control, electrical, water supply, water making, heating and ventilation parts. The condenser field is composed of a large number of condensing devices (such as heliostats) arranged according to certain rules. At present, the investment of condenser field accounts for more than 60% of the total system investment in various solar power generation systems, and the annual average efficiency of condenser field is generally 58% to 72%. How to improve the condensing efficiency of the mirror field through technical means is one of the important problems faced by the current tower type molten salt solar thermal power station technology.

[0003] The heliostat in the existing tower type molten salt solar thermal power station condensing field (heliostat field) generally uses a ground column to support the mirror body structure and the rotation control device (revolving speed reducer). Due to the construction deviation in the column installation process and the production deviation in the column production process, the top plane of the column cannot be absolutely parallel to the horizontal plane, resulting in a certain angle. The existence of this angle will further cause the reflected light spot of the heliostat to not be able to focus on the target position during condensation, thereby reducing the condensation efficiency.

[0004] For the common heliostat column and foundation integrated form (i.e. an entire PHC pipe pile or a steel pile, part of which is buried in the foundation as a pile foundation, and the other part is exposed to the ground as a column), a leveling flange plate is usually arranged on the top surface of the column, a screw rod is arranged on the top surface of the flange plate, an upper nut and a lower nut are arranged on the screw rod, and the rotating speed reducer base is arranged on the screw rod between the upper and lower nuts. The position of the rotating speed reducer base is leveled by adjusting the positions of the upper and lower nuts.

[0005] In order to ensure the rigidity of the connection between the rotary reducer and the flange, the number of bolts is not easy to be too small, and the spacing between the rotary reducer base and the flange is not easy to be too large, which leads to the extremely limited angle range of this leveling method, generally 1°~2°, so the angle deviation cannot exceed this range value, which puts higher requirements on the construction deviation and production deviation, thereby increasing the construction and production difficulty and reducing the production and installation efficiency. And when the angle leveling operation is performed, the nut position of all bolts needs to be determined through multiple attempts, and this leveling method also reduces the overall installation efficiency. Practical new type content

[0007] In order to achieve the above object, the utility model provides a spherical leveling support, the support includes an upper support plate, a lower support plate, a connecting piece and an L-shaped connecting plate, the upper support plate is connected with the lower support plate through the connecting piece and the L-shaped connecting plate, and the spherical crown plate at the bottom of the upper support plate is matched with the spherical support seat of the lower support plate.

[0008] Further, the upper support plate is composed of a top plate and a spherical crown plate, the spherical crown plate is arranged at the center position of the bottom surface of the top plate, and the spherical crown plate is designed in a spherical arc.

[0009] Further, the lower support plate is composed of a bottom plate and a spherical support seat, and the spherical support seat is arranged at the center position of the bottom plate, and the top surface of the spherical support seat is designed in a concave surface.

[0010] Further, the number of the connecting pieces is not less than 3.

[0015] Further, the connecting piece fixes and connects the L-shaped connecting plate and the stand column through bolts.

[0016] Further, bolt holes are arranged on the upper support plate for connecting the rotary reducer.

[0017] Compared with the prior art, the spherical leveling support has the following beneficial effects: 1. The spherical leveling support has the advantages of flexible and simple angle adjusting mode, large adjustable angle range, and the ability to adjust the leveling in any horizontal direction, thereby improving the light condensation efficiency, reducing the difficulty of column construction and production, and improving the production and installation efficiency; 2. The spherical leveling support can be designed according to the required leveling angle range, such as the height of the support and the spherical arc, to meet the required angle leveling requirements.
