Description

Technical Field

[0001] The utility model relates to the technical field of equipment of a photothermal power station, in particular to a stabilizing support device for a heliostat in a photothermal power station. Background Art

[0002] A heliostat is an optical device that reflects light from the sun or other celestial bodies in a fixed direction. It is also called a star-fixing mirror. Its function is similar to that of a coelostat, but it uses a plane mirror placed in an equatorial device that can move in the declination direction. When the mirror tracks at the speed of diurnal motion, sunlight or starlight is reflected in the direction of the polar axis and then reflected into a fixed telescope directly or through an auxiliary plane mirror. Compared with a coelostat, its main advantage is that it does not require guide rails and has a simple and compact structure.

[0003] For example, the heliostat support device, entitled "CN218565786U," utilizes rectangular connecting plates and tray columns welded together and riveted to the heliostat frame. This allows the tray columns to be fixed at any angle while ensuring a secure connection. However, the heliostat support device utilizes relatively thin tray columns to support and secure the entire heliostat. Because heliostats are often fixed in large numbers over large areas in locations like deserts or Gobi deserts where there is no sunlight shielding, and because strong winds and sand are common in outdoor environments like Gobi deserts, strong forces are applied to the tops of the thin tray columns when large heliostats are blown by strong winds. Over time, the tray columns of the heliostat support device may bend and wobble, affecting the stability of the support device.

[0004] At the same time, in the existing heliostat support device, the lower end of the entire heliostat support device needs to be plugged and fixed to the frame through a connecting plate. However, the pallet column can only be connected to the frame by relying on the relatively weak connecting plate. Therefore, the connecting plate will exert a forward pulling force outward, causing the pallet column to easily fall off the frame in windy weather, thereby shortening the service life of the heliostat support device. Utility Model Content

[0005] The purpose of the utility model is to solve the problems of poor support stability and short service life of existing heliostat support devices, and to propose a stable support device for heliostats in a solar thermal power station.

[0007] A heliostat stabilization support device for a solar thermal power station is designed, comprising a column, a heliostat fixing plate, and a heliostat mirror surface.

[0010] Preferably, the firmly fixed installation structure includes a base and a support platform, the support platform is fixedly connected to the lower end of the column, the lower end of the support platform is fixedly connected to the base, the lower end of the base is fixedly connected to multiple anchor cones, and multiple support plates are fixedly connected above the support platform, and the side walls of the multiple support plates are fixedly connected to the outer side of the lower end of the column.

[0011] Preferably, a plurality of shaping frames are fixedly connected to the rear side of the outer wall of the heliostat fixing plate, and a plurality of diagonal supports are fixedly connected between the inner sides of the plurality of shaping frames.

The reinforcement rods are made of a high-strength carbon steel alloy. The reinforcement rods fix the lamination frames and the connecting blocks, which are spread out on both sides, by rotating locking bolts. In this way, the lamination frames can fully support and connect the entire heliostat fixing plate. In this way, when the heliostat is installed in the Gobi Desert where strong winds are common, the connection between the top of the column and the heliostat fixing plate can be improved, thereby improving the support stability of the heliostat stabilization support device for a solar thermal power station.

[0025] The heliostat stabilizing mounting structure 6 includes a connecting block 61 and a bonding frame 65. Multiple bonding frames 65 are movably connected to the rear side of the heliostat fixing plate 2. Made of aluminum alloy, there are eight bonding frames 65, each of which is fixedly connected to the heliostat fixing plate 2 via fixing screws 66. The internal threads of the bonding frames 65 are connected to multiple fixing screws 66, and the ends of the multiple fixing screws 66 are connected to the internal threads of the heliostat fixing plate 2. The rear sides of the multiple bonding frames 65 are fixed to the transverse plate 64 by welding, and one end of the multiple bonding frames 65 is fixedly connected to the transverse plate 64.

[0026] The side walls of multiple transverse plates 64 are fixedly connected to reinforcement rods 63, which are made of high-strength carbon steel alloy. The reinforcement rods 63 fix the fitting frames 65 opened on both sides to the connecting block 61 by rotating locking bolts 62. In this way, the fitting frames 65 can fully support and connect the entire heliostat fixing plate 2. In this way, when the heliostat is installed in the Gobi Desert where strong winds are common, the connection between the top of the column 1 and the heliostat fixing plate 2 can be improved. The other ends of the multiple reinforcement rods 63 are movably connected to the connecting block 61. The inner side of the connecting block 61 is threadedly connected to the locking bolt 62, and the end of the locking bolt 62 is threadedly connected to the reinforcement rod 63.

The rear sides of the multiple laminating frames 65 are fixed to the transverse plate 64 by welding. The reinforcement rods 63 are made of high-strength carbon steel alloy. The reinforcement rods 63 fix the laminating frames 65 opened on both sides to the connecting block 61 by rotating locking bolts 62. In this way, the laminating frames 65 can fully support and connect the entire heliostat fixing plate 2. In this way, when the heliostat is set in the Gobi Desert where strong winds often occur, the connection between the top of the column 1 and the heliostat fixing plate 2 can be improved, thereby improving the support stability of the stable support device for the heliostat in the solar thermal power station.

The extension rods 46 will be welded to the two ends of the transverse rod 42. The outer walls of the two extension rods 46 are fixedly sleeved with limit rings 45. The limit rings 45 can prevent the transverse rod 42 from sliding and falling off on the inner side of the top rod 41. The outer side of the transverse rod 42 is fixed with multiple through holes 44.

[0029] The through holes 44 are provided with two relatively parallel rows. Under normal circumstances, the extension rods 46 can change their direction angle as the inner transverse rods 42 rotate, so that the orientation angle of the front heliostat fixing plate 2 can be adjusted as needed. After the angle of the heliostat fixing plate 2 is determined, the two screws 43 can be inserted simultaneously at different angles of the top rod 41. The screws 43 are then rotated and screwed, and the ends of the screws 43 are inserted into the through holes 44. In this way, the screws 43 can lock the rotation of the transverse rods 42, thereby fixing the angle of the heliostat fixing plate 2. The outer side of the top rod 41 is threadedly connected to the two screws 43. The inner sides of the two screws 43 are movably connected to the inner side of the through hole 44.

A variety of structures are used to reinforce the fixation of the lower end to improve the service life of the stable support device of the heliostat in the solar thermal power station.

[0033] Working principle:

[0034] When using the heliostat stabilization support device of a large-scale CSP plant, a certain number and density of heliostat stabilization support structures are erected on the ground near the CSP tower of a large CSP plant. Then, the heliostat mirrors are aligned obliquely toward the top of the CSP tower. In this way, sunlight will be reflected by the heliostats to the CSP tower for solar energy extraction and storage.

[0035] The firm and stable installation structure of the heliostat stabilization support device of a CSP station:

[0036] The bonding frames 65 are made of aluminum alloy, and there are eight bonding frames 65. The eight bonding frames 65 are fixedly connected to the heliostat fixing plate 2 by tightening screws 66. The rear sides of the multiple bonding frames 65 are fixed to the transverse plate 64 by welding. The reinforcement rods 63 are made of high-strength carbon steel alloy. The reinforcement rods 63 fix the bonding frames 65 opened on both sides to the connecting block 61 by rotating locking bolts 62. In this way, the bonding frames 65 can fully support and connect the entire heliostat fixing plate 2. In this way, when the heliostat is set in the Gobi Desert where strong winds are common, the connection between the top of the column 1 and the heliostat fixing plate 2 can be improved.

The through hole 44 is provided with two relatively parallel rows. Under normal circumstances, the extension rod 46 can change the direction angle as the inner transverse rod 42 rotates, so that the orientation angle of the front heliostat fixing plate 2 can be adjusted as needed. After the angle of the heliostat fixing plate 2 is determined, the two screws 43 can be inserted at different angles of the top rod 41 at the same time, and then the screw 43 is rotated and screwed. The end of the screw 43 is inserted into the through hole 44. In this way, the screw 43 can lock the rotation of the transverse rod 42, thereby fixing the angle of the heliostat fixing plate 2.
