Description

Technical Field

[0001] This utility model relates to the field of actuator technology, and in particular to an elevation actuator for a heliostat in a central tower power station. Background Technology

[0002] Against the backdrop of global energy transition, solar energy, as an important form of clean and renewable energy, has attracted much attention for its efficient utilization technologies. Central tower solar thermal power plants use a large-scale heliostat array to reflect sunlight onto a central collection tower, heating heat transfer fluids to drive turbines for power generation, demonstrating high photothermal conversion efficiency and potential for large-scale application. As the core component of this system, the heliostats need to dynamically adjust their azimuth and elevation angles to track the sun's position in real time, ensuring that the reflected light is continuously focused on the receiver at the top of the tower. Therefore, the stability and accuracy of their drive mechanism directly affect the overall system efficiency. In existing technologies, when the drive mechanism malfunctions, the entire system needs to be disassembled and repaired, a cumbersome, time-consuming, and costly process. Utility Model Content

[0003] The purpose of this invention is to solve the shortcomings of the existing technology, which requires disassembly and repair of the entire system when the drive part fails. The repair process is cumbersome, time-consuming, labor-intensive, and costly. Therefore, an elevation driver for a heliostat in a central tower power station is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An elevation actuator for a heliostat in a central tower power station includes a base, a T-shaped hollow column, and two side plates. The T-shaped hollow column is vertically fixed to the upper end of the base, and the two side plates are symmetrically fixed to the two ends of the T-shaped hollow column. The actuator also includes two adjustment mechanisms symmetrically arranged at the two ends of the T-shaped hollow column. These adjustment mechanisms are used to avoid the need for complete disassembly and repair when the actuator fails. During repair, only the rods need to be replaced, resulting in lower repair costs and greater time and effort savings.

[0005] As a preferred embodiment of this utility model, the adjustment mechanism includes: two bottom columns, an arc-shaped rod, a top rod, a connecting rod, an active rod, and two U-shaped blocks; Both base columns are fixedly connected to the side plates. The center of the arc-shaped rod and one end of the top rod are respectively rotatably sleeved on the two base columns. The extension ends of the arc-shaped rod and the top rod are both U-shaped. The two ends of the connecting rod are respectively rotatably connected to the inner walls on both sides of the U-shaped end of the arc-shaped rod and the U-shaped end of the top rod. One end of the driving rod is rotatably connected to one end of the arc-shaped rod. The other ends of the top rod and the driving rod are respectively rotatably connected to the inner walls on both sides of the two U-shaped blocks. The same driving component is provided between the two driving mechanisms.

[0006] Furthermore, by pulling the other end of the arc-shaped rod, the arc-shaped rod rotates around one of the base columns. The rotational force of the arc-shaped rod then presses down on the connecting rod and pushes up the driving rod. Simultaneously, one end of the arc-shaped rod rotates around one end of the driving rod. This allows the downward force of the connecting rod to press down on the U-shaped end of the top rod, causing the top rod to rotate around the other base column. At the same time, both ends of the connecting rod rotate around the inner walls of the U-shaped ends of the arc-shaped rod and the top rod, respectively. This allows the two U-shaped blocks to move along with the other ends of the top rod and the driving rod. This allows for adjustment of the heliostat's angle and avoids the need for complete disassembly and repair when the drive unit malfunctions. During repair, only the rods need to be replaced, resulting in lower repair costs and saving time and effort.

[0007] As a preferred embodiment of this utility model, the propulsion assembly includes: an electro-hydraulic rod, a connecting block, and a U-shaped rod; One end of the electro-hydraulic rod slides through one side of the T-shaped hollow column and is fixedly connected to the inclined surface inside the T-shaped hollow column. The connecting block is fixedly connected to the other end of the electro-hydraulic rod and rotatably sleeved on the U-shaped rod. The two ends of the U-shaped rod are respectively rotatably connected to the other ends of two arc-shaped rods.

[0008] Furthermore, by activating the electro-hydraulic rod, the electro-hydraulic rod extends to advance the connecting block and the U-shaped rod. At the same time, the connecting block rotates around the U-shaped rod as the center, and the two ends of the U-shaped rod rotate around the other ends of the two arc-shaped rods, thereby pulling the other ends of the two arc-shaped rods.

[0009] In a preferred embodiment of this utility model, the four U-shaped blocks are fixedly connected to the same base frame, and multiple support rods are symmetrically fixedly connected to the base frame at equal intervals. The multiple support rods are fixedly connected to the same mounting frame, and the mounting frame is fixedly connected to the mirror body.

[0010] Furthermore, the mirror body is fixedly connected to four U-shaped blocks via a base frame, multiple support rods are fixedly connected to the base frame at equal intervals, the mounting bracket is fixedly connected to multiple support rods, and the mirror body is fixedly connected to the mounting bracket, thereby supporting the mirror body. Beneficial effects

[0011] First, pull the other end of the curved rod to make it rotate around one of the base columns. Then, use the rotational force of the curved rod to press down the connecting rod and push up the driving rod. In this way, the downward force of the connecting rod can be used to press down the U-shaped end of the top rod and make the top rod rotate around the other base column. This allows the two U-shaped blocks to move along with the other ends of the top rod and the driving rod. This allows the angle of the heliostat to be adjusted and avoids the need for complete disassembly and repair when the drive part fails. During repair, only the rods need to be replaced, which is less expensive and saves more time and effort.

[0012] In this invention, the angle of the heliostat is adjusted by activating the adjustment mechanism, which avoids the need for complete disassembly and repair when the drive part fails. During repair, only the rods need to be replaced, resulting in lower repair costs and greater time and effort savings. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-4 An elevation actuator for a heliostat in a central tower power station includes a base 1, a T-shaped hollow column 2, and two side plates 6. The T-shaped hollow column 2 is vertically fixed to the upper end of the base 1, and the two side plates 6 are symmetrically fixed to the two ends of the T-shaped hollow column 2. The actuator also includes two adjustment mechanisms symmetrically arranged at the two ends of the T-shaped hollow column 2. These adjustment mechanisms are used to avoid the need for complete disassembly and repair when the actuator fails. During repair, only the rods need to be replaced, resulting in lower repair costs and greater time and effort savings.

[0017] Using the above structure: To further address the problem that when the drive unit malfunctions, it requires complete disassembly and repair, which is cumbersome, time-consuming, labor-intensive, and costly, as follows: Figure 2 and Figure 3 As shown, firstly, the other end of the arc-shaped rod 8 is pulled, causing the arc-shaped rod 8 to rotate around one of the base columns 7. Then, the rotational force of the arc-shaped rod 8 is used to press down the connecting rod 10 and push up the active rod 11. In this way, the downward force of the connecting rod 10 can be used to press down the U-shaped end of the top rod 9 and make the top rod 9 rotate around the other base column 7. This allows the two U-shaped blocks 12 to move along with the other end of the top rod 9 and the other end of the active rod 11. This allows the angle of the heliostat to be adjusted and avoids the need for complete disassembly and repair when the drive part fails. During repair, only the rods need to be replaced, resulting in lower repair costs and saving more time and effort.

[0018] In this utility model, the adjustment mechanism includes: two bottom columns 7, an arc-shaped rod 8, a top rod 9, a connecting rod 10, an active rod 11, and two U-shaped blocks 12; like Figure 2 and Figure 3 As shown, both bottom columns 7 are fixedly connected to the side plate 6. The center of the arc-shaped rod 8 and one end of the top rod 9 are respectively rotatably sleeved on the two bottom columns 7, and the extension ends of the arc-shaped rod 8 and the top rod 9 are both U-shaped. The two ends of the connecting rod 10 are respectively rotatably connected to the inner walls on both sides of the U-shaped ends of the arc-shaped rod 8 and the top rod 9. One end of the driving rod 11 is rotatably connected to one end of the arc-shaped rod 8, and the other ends of the top rod 9 and the driving rod 11 are respectively rotatably connected to the inner walls on both sides of the two U-shaped blocks 12. The two driving mechanisms are provided with the same driving component. By pulling the other end of the arc-shaped rod 8, the arc-shaped rod 8 is rotated around one of the bottom columns 7 as the center, and then the rotational force of the arc-shaped rod 8 is used to drive the connecting rod 10. The downward pressure is applied to push the active rod 11 upwards, while one end of the arc-shaped rod 8 rotates around the end of the active rod 11. This allows the downward force of the connecting rod 10 to press down on the U-shaped end of the top rod 9, causing the top rod 9 to rotate around the other bottom column 7. At the same time, both ends of the connecting rod 10 rotate around the inner walls of the U-shaped ends of the arc-shaped rod 8 and the top rod 9, respectively. This allows the two U-shaped blocks 12 to move along with the other ends of the top rod 9 and the active rod 11. This allows for adjustment of the heliostat angle and avoids the need for complete disassembly and repair when the drive unit malfunctions. During repair, only the rods need to be replaced, resulting in lower repair costs and greater time and effort savings.

[0019] In this invention, the propulsion assembly includes: an electro-hydraulic rod 3, a connecting block 4, and a U-shaped rod 5.

[0020] like Figure 1 and Figure 4 As shown, one end of the electric hydraulic rod 3 slides through one side of the T-shaped hollow column 2 and is fixedly connected to the inclined surface inside the T-shaped hollow column 2. The connecting block 4 is fixedly connected to the other end of the electric hydraulic rod 3 and rotatably sleeved on the U-shaped rod 5. The two ends of the U-shaped rod 5 are respectively rotatably connected to the other ends of the two arc rods 8. By activating the electric hydraulic rod 3, the electric hydraulic rod 3 extends to push the connecting block 4 and the U-shaped rod 5. At the same time, the connecting block 4 rotates around the U-shaped rod 5 as the center, and the two ends of the U-shaped rod 5 rotate around the other ends of the two arc rods 8 as the center, so that the other ends of the two arc rods 8 can be pulled.

[0021] To support the mirror body 16, such as Figure 1 and Figure 2 As shown, the four U-shaped blocks 12 are fixedly connected to the same base frame 13. Multiple support rods 14 are symmetrically fixedly connected to the base frame 13 at equal intervals. The multiple support rods 14 are fixedly connected to the same mounting frame 15. The mirror body 16 is fixedly connected to the mounting frame 15. The mirror body 16 is fixedly connected to the four U-shaped blocks 12 through the base frame 13. The multiple support rods 14 are fixedly connected to the base frame 13 at equal intervals. The mounting frame 15 is fixedly connected to the multiple support rods 14, and the mirror body 16 is fixedly connected to the mounting frame 15, thereby supporting the mirror body 16.

[0022] It should be noted that the specific model of the electro-hydraulic rod 3 to be used is to be selected by those skilled in the art, and the electro-hydraulic rod 3 mentioned above is all existing technology, which will not be elaborated on in this solution.

[0023] The working principle of this utility model is as follows: First, the electric hydraulic rod 3 is activated. The electric hydraulic rod 3 extends to advance the connecting block 4 and the U-shaped rod 5. At the same time, the connecting block 4 rotates around the U-shaped rod 5. The two ends of the U-shaped rod 5 rotate around the other ends of the two arc-shaped rods 8, respectively. This pulls on the other ends of the two arc-shaped rods 8, causing the arc-shaped rods 8 to rotate around one of the bottom posts 7. The rotational force of the arc-shaped rods 8 then presses down on the connecting rod 10 and pushes up the driving rod 11. Meanwhile, one end of the arc-shaped rod 8 rotates around one end of the driving rod 11. This allows the downward force of the connecting rod 10 to push the U-shaped rod 9. The U-shaped end is pressed down, causing the top rod 9 to rotate around the other bottom column 7 as the center. At the same time, the two ends of the connecting rod 10 rotate around the inner walls of the two sides of the U-shaped end of the arc rod 8 and the U-shaped end of the top rod 9, respectively. This allows the two U-shaped blocks 12 and the base frame 13 to move along with the other end of the top rod 9 and the other end of the active rod 11. This allows the multiple support rods 14 and the mounting bracket 15 to move, which in turn allows the mirror body 16 to move. This allows the angle of the heliostat to be adjusted and avoids the need for complete disassembly and repair when the drive part fails. During repair, only the rods need to be replaced, resulting in lower repair costs and greater time and effort savings.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
