Description

Technical Field

[0001] This application relates to the field of photothermal support technology, and more particularly to a photoelectric probe structure and a photothermal support. Background Technology

[0002] The solar thermal support structure is the core of solar thermal power generation. It uses heliostats to track the sun so that the reflected light can be accurately projected onto the heat exchange surface of the receiver placed on top of the receiving tower. The receiver converts solar energy into heat energy and heats the medium (water or other fluids) flowing in the coil to produce medium- and high-temperature steam, thereby driving the steam turbine generator set to generate electricity.

[0003] Currently, most heliostats on the market use astronomical algorithms for tracking. However, due to errors in construction and installation, the tracking accuracy is not high. To further improve the tracking accuracy of tower-type dual-axis heliostats, photoelectric probes are added and installed near the reflecting mirror of the heliostat to help it reflect light more accurately. Once the angle of the photoelectric probe is adjusted, it cannot be changed, so it is usually installed on the ground using an additional column. This undoubtedly increases the amount of construction work and occupies maintenance space.

[0004] Therefore, how to improve the technical defects existing in the prior art has always been a problem that ordinary people skilled in the art need to solve. Summary of the Invention

[0005] The purpose of this application is to provide a photoelectric probe structure and a photothermal support that integrates the photoelectric probe and the photothermal support together, eliminating the construction process of fixing the photoelectric probe to the ground, shortening the construction period, reducing labor costs, and saving space by eliminating the need for ground installation of the photoelectric probe, providing sufficient space for subsequent maintenance and cleaning of the heliostat, and avoiding affecting the normal driving of maintenance vehicles.

[0012] Furthermore, the clamp assembly also includes a third docking part, which is equipped with a second bearing, which is sleeved on the outside of the second rotating shaft.

[0013] Furthermore, there are two clamp groups, which are spaced apart along the axis of the column; the connector has two mounting ears corresponding to the two clamp groups, and the second rotating shaft passes through the mounting ears and the clamp groups to realize the rotational connection between the connector and the base.

[0014] Furthermore, it also includes: A first mounting base and a second mounting base are provided, wherein the first mounting base is installed at the end of the support rod away from the fixed base, and the second mounting base is installed at the first mounting base, for mounting the photoelectric probe; The first mounting base has a first adjustment hole for adjusting the azimuth angle of the first mounting base.

The first mounting base also has a second adjustment hole for adjusting the pitch angle of the second mounting base relative to the first mounting base. A fastener passes through the second adjustment hole to lock the second mounting base to the first mounting base and limit the pitch angle of the photoelectric probe.

[0015] Furthermore, both the first adjustment hole and the second adjustment hole are arc-shaped holes, and the first mounting base has a fixing hole at the center of the arc of the second adjustment hole. The fastener passes through the fixing hole to rotatably fix the second mounting base to the first mounting base.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] Currently, photoelectric probes are generally installed on the ground using additional pillars, which increases the amount of ground construction. Furthermore, the pillars installed on the ground occupy maintenance space, resulting in a large site footprint and an unsightly appearance for solar thermal power plant projects.

[0028] For this, see Figures 1 to 3This application provides a photoelectric probe mounting structure that is installed on a solar thermal support, integrating the photoelectric probe 500 onto the support without requiring additional ground-based fixing structures. This eliminates the need for ground-based fixing of the photoelectric probe 500, shortens the construction period, and saves labor costs. Furthermore, it effectively saves space, providing sufficient room for subsequent maintenance and cleaning of the heliostat 803, avoiding interference with the normal operation of maintenance vehicles, and resulting in a cleaner and more aesthetically pleasing solar thermal power plant project.

[0029] In one specific embodiment, see Figure 3 and Figure 4 The photoelectric probe mounting structure includes a photoelectric probe 500, a support rod 200, a base 710, and a connector 300. The support rod 200 is vertically mounted at the center of the mirror surface of the heliostat assembly 803 of the solar thermal support. The photoelectric probe 500 is mounted on top of the support rod 200. The support rod 200 passes through the gap between the two heliostats in the heliostat assembly 803 from bottom to top, so that the photoelectric probe 500 is positioned above the heliostat assembly 803 of the solar thermal support. The base 710 is used to fix it to the column of the solar thermal support. The connector 300 is connected to both the support rod 200 and the base 710, and is used to fix the support rod 200 to the base 710. By integrating the photoelectric probe mounting structure into the solar thermal support, there is no need to add an additional fixing structure on the ground, eliminating the construction process of fixing the photoelectric probe to the ground, shortening the construction period, and saving labor costs.

[0030] The solar thermal support includes a column 700, a drive unit 600, a mounting base 100, a main shaft 801, purlins 802, and a heliostat assembly 803. The drive unit 600 is mounted on the top of the column 700, the mounting base 100 is fixed to the top of the drive unit 600, the main shaft 801 is connected to the drive unit 600 for transmission, and the heliostat assembly 803 is mounted on the main shaft 801 via the purlins 802.

[0031] Drive unit 600 is a dual-axis rotary drive mechanism. For details, please refer to [link / reference needed]. Figure 4As shown, the drive device 600 includes a first rotary mechanism 620 and a second rotary mechanism 630. The first rotary mechanism 620 and the second rotary mechanism 630 are sequentially arranged at the top of the column 700 along the height direction of the column 700. The first rotary mechanism 620 includes a first drive motor 621, and the second rotary drive mechanism 630 includes a second drive motor 631. The first drive motor 621 and the second drive motor 631 are arranged vertically. The second rotary mechanism 630 is located above the first rotary mechanism 620, and the main shaft 801 of the photothermal support is connected to the power output shaft of the second rotary mechanism 630. Driven by the second drive motor 631 of the second rotary mechanism 630, the main shaft 801, the purlin 802 fixedly connected to the main shaft 801, and the heliostat assembly 803 fixed to the purlin 802 are driven to rotate around the axis of the drive main shaft 801, thereby adjusting the pitch angle of the heliostat assembly 803.

[0032] Driven by the first drive motor 621, the second rotary mechanism 630, the main shaft 801, the purlin 802 fixedly connected to the main shaft 801, and the heliostat assembly 803 fixed to the purlin 802 are driven to rotate around the axis of the column 700, thereby adjusting the azimuth angle of the heliostat assembly 803. The fixed seat 100 is provided on the second rotary mechanism 630.

[0033] The first rotary mechanism 620 further includes a first input shaft, a first transmission component group, and a first output shaft. The first input shaft is connected to the first drive motor 621 and the first transmission component group, respectively. The first transmission component group is connected to the first output shaft. The power of the first drive motor 621 is transmitted to the first output shaft sequentially through the first input shaft and the first transmission component group. The first output shaft is connected to the second rotary mechanism 630, thereby driving the second rotary mechanism 630 to rotate around the axis of the first output shaft. The axis of the first output shaft is coaxial with the axis of the column 700. The second rotary mechanism 620 further includes a second input shaft, a second transmission component group, and a second output shaft. The second input shaft is connected to the second drive motor 631 and the second transmission component group, respectively. The second transmission component group is connected to the second output shaft, and the second output shaft is connected to the main shaft 801. Driven by the second drive motor 631, the second input shaft, the second transmission component group, and the second main shaft rotate, thereby driving the main shaft 801 and the heliostat assembly 803 mounted on the main shaft 801 to rotate. The first and second transmission components can be in the form of gear transmission, worm gear transmission, bevel gear transmission, etc.

[0034] Please continue to refer to this. Figure 4 and Figure 5As shown, in actual production, the top of the second rotary mechanism 630 is often arc-shaped. To achieve stable fixation of the fixed seat 100 and the support rod 200, the top of the second rotary mechanism 630 can be provided with at least two protruding supports 610, and the top surfaces of these supports 610 are all on the same horizontal plane, providing a plane for the fixed seat 100 to be installed, thus improving the stability of the overall structure. Preferably, there are four supports 610. The fixed seat 100 is machined and fixed to these four protruding supports 610 to support the weight of the upper photoelectric probe 500 and the support rod 200. The fixed seat 100 includes a connecting part 110 and a main body 120. The main body 120 has a hollow cavity. The connecting part 110 is fixedly connected to the supports 610, thereby fixing the fixed seat 100 to the second rotary mechanism 630.

[0035] One end of the support rod 200 is rotatably mounted on the fixed base 100. Specifically, one end of the support rod 200 can directly extend into the fixed base 100 and be rotatably connected to it. To improve the stability and smoothness of the relative rotation between the fixed base 100 and the support rod 200, and to prevent the drive device 600 from affecting the support rod 200 during operation, a first bearing 122 can also be provided inside the fixed base 100, which is sleeved on the outside of the support rod 200. When the drive device 600 drives the main shaft 801 and the heliostat assembly 803 to rotate around the axis of the column 700, or around the axis of the main shaft 801, the support rod 200 does not interfere with the lenses in the heliostat assembly 803.

[0036] Or see Figure 5 Alternatively, a flange shaft 121 can be provided at the end of the support rod 200 away from the photoelectric probe 500. This flange shaft 121 is fixedly connected to the support rod 200 and extends into the cavity of the fixed seat 100, rotatably connecting with the fixed seat 100, thus achieving a rotatable connection between the support rod 200 and the fixed seat 100. This structure also serves the function of the first bearing 122. In this case, to improve the stability and smoothness of the relative rotation between the fixed seat 100 and the support rod 200, and to prevent the drive device 600 from affecting the support rod 200 during operation, a first bearing 122 can also be provided inside the fixed seat 100. This first bearing 122 is sleeved on the outside of the flange shaft 121. The flange shaft 121 is preferably machined and rotatably connected to the fixed seat 100 via the first bearing 122. One end of the flange shaft 121 extends out of the fixed seat 100 and is fixedly connected to one end of the support rod 200. The support rod 200 is preferably made of steel pipe profile welded with flange. The flange at one end of the support rod 200 is connected to the flange shaft 121, and the flange at the other end is used to install the photoelectric probe 500.

[0037] In this embodiment, a first bearing 122 is provided to support the relative rotation between the flange shaft 121 and the fixed seat 100. Combined with the connecting piece 300, this ensures that when the drive device 600 rotates the drive spindle 801 around the axis of the column 700, only the fixed seat 100 rotates horizontally with the drive device 600, while the flange shaft 121 and the support column 200 remain stationary, thus guaranteeing that the position of the photoelectric probe 500 remains unchanged. Furthermore, due to the presence of the first bearing 122, the fixed seat 100 can rotate more smoothly relative to the flange shaft 121 without jamming, thus not affecting the operation of the drive device 600 or the support column 200.

[0038] The first bearing 122 is preferably a roller bearing, which has an inner ring and an outer ring. When the fixed seat 100 rotates synchronously with the second rotating mechanism 630 under the drive of the first rotating mechanism 620, the outer ring of the bearing rotates synchronously with the fixed seat 100, while the inner ring of the bearing remains stationary. This is more conducive to ensuring that the position of the photoelectric probe 500 remains unchanged. Moreover, the roller bearing has a standard size, is interchangeable, and is easy to disassemble and assemble, which is conducive to mass production and use.

[0039] The first bearing 122 within the fixed base 100 also supports the support rod 200 and the photoelectric probe 500. Therefore, generally speaking, the more first bearings 122 there are, the more stable the photoelectric probe 500 will be. In one example embodiment, there are two first bearings 122, which are spaced apart along the height direction of the flange shaft 121. A sleeve 123 is also fitted over the flange shaft 121, located between the two first bearings 122. The sleeve 123 abuts against the inner ring of the first bearing 122, thereby providing upward support and limiting for the upper bearing 122 and preventing it from sliding down. Conversely, a limiting seat 124 is also installed at the end of the flange shaft 121 away from the support rod 200, which provides upward support and limiting for both first bearings 122, preventing them from sliding down. Through the arrangement of the sleeve 121 and the limiting seat 124, the first bearings 122 are stably limited to their respective positions on the flange shaft 121. The flange shaft 121 is preferably a hollow structure. The limiting seat 124 includes a main body 1241 and a limiting part 1242. The main body 1241 extends into the cavity of the flange shaft 121 and is fixedly connected to the flange shaft 121 by threaded fastening or interference fit. When the main body 1241 and the flange shaft 121 are threadedly fastened, threads are respectively provided on the circumferential outer surface of the main body 1241 and the inner wall of the cavity of the flange shaft 121. The fixed connection between the limiting seat 124 and the flange shaft 121 is achieved by tightening the main body 1241. The limiting part 1242 abuts against the bottom end face of the flange shaft 121, and the limiting part 1242 has an extension 1243 away from the axis of the limiting seat 124. The extension 1243 is located below the first bearing 122, which facilitates installation and also provides a limiting function for the first bearing 122 to prevent the first bearing 122 from falling out of the fixed seat 100. It should be noted that there is a certain distance between the limiting seat 124 and the outer peripheral surface of the second rotating mechanism 630, so as to ensure that the position of the photoelectric probe 500 will not change due to the influence of the second rotating mechanism 630 during the rotation of the limiting seat 124.

[0040] Please continue to refer to this. Figure 4 As shown, the base 710 is fixed to the column 700; the support rod 200 also includes a fixing member 210, one end of which is fixedly connected to the support rod 200. Both ends of the connecting member 300 are connected to the base 710 and the fixing member 210 respectively, thereby fixing the support rod 200 to the column 700 via the connecting member 300. By ensuring that the positional relationship between the fixing member 210 and the base 710 remains unchanged, the positional relationship between the support rod 200 and the column 700 is defined, thereby limiting the azimuth angle of the support rod 200 and the photoelectric probe 500 on it.

[0041] Considering that the drive device 600 also drives the main shaft 801 to rotate around its own axis to deflect the heliostat assembly 803, during the deflection process, the photothermal support (e.g., the purlins 802 arranged on the main shaft 801) may interfere with the connector 300. In a preferred embodiment, the two ends of the connector 300 are rotatably connected to the base 710 and the fixed member 210, respectively. In this way, when the drive device 600 drives the main shaft 801 to rotate around its own axis, the connector 300, after being subjected to external forces (e.g., the purlins 802), can rotate relative to the fixed member 210 and the base 710 to provide clearance, providing sufficient space for the normal operation of the heliostat assembly 803, without affecting the dual-axis rotation of the photothermal support, and the support rod 200 remains stationary during this process. The structure is reasonable and practical.

[0042] Specifically, see Figure 4 and Figure 6 The two ends of the connector 300 are connected to the fixed member 210 and the base 710 respectively via a first rotating shaft 330 and a second rotating shaft 360. The two ends of the connector 300 are respectively provided with a first mating portion 310 and a second mating portion 320. The first rotating shaft 330 is fixedly mounted on the first mating portion 310, and the first rotating shaft 330 can be fixedly connected to the first mating portion 310 by welding or bolt fastening. The second mating portion 320 has a first opening 340. The fixed member 210 is fixed to one end of the support rod 200 for mating with the fixed seat 100 (for example, integrally formed on one end of the support rod 200 connecting flange shaft 121, or fixedly connected to the support rod 200 or flange shaft 121 by welding, bolting, or riveting). The end of the fixed member 210 away from the support rod 200 has a second opening 211, through which the first rotating shaft 330 rotatably passes.

[0043] Please refer to Figures 4 to 8 As shown, the base 710 includes at least one clamp assembly, which includes a first clamp member 711 and a second clamp member 712. The first clamp member 711 and the second clamp member 712 together clamp the outside of the column 700, and one of the first clamp member 711 and the second clamp member 712 is rotatably connected to the connector 300 via a second rotating shaft 360. For example, one of the first clamp member 711 and the second clamp member 712 is provided with a third mating portion 713, and a third opening 714 is provided on the third mating portion 713. The two ends of the second rotating shaft 360 pass through the first opening 340 and the third opening 714 respectively, so as to realize the rotatable connection between the second mating portion 320 and the third mating portion 713.

[0044] In this embodiment, the connection between the connector 300 and the column 700 is achieved through the clamp assembly. The connector 300 is then connected to the support rod 200 through the engagement of the first rotating shaft 330 and the pin of the second opening 211, thereby achieving a fixed connection between the photoelectric probe 500 and the column 700 and ensuring that the position of the photoelectric probe 500 does not change. If it is necessary to change the azimuth angle of the photoelectric probe 500, the operator can also adjust the clamp assembly to change the orientation of the third mating part 713, and then the first rotating shaft 330 on the connector 300 limits the orientation of the fixing part 210, thereby changing the azimuth angle of the photoelectric probe 500. The operation is convenient and quick, which is conducive to the operator to reasonably control the angle of the photoelectric probe 500. Alternatively, the orientation of the connector 300 and the fixing part 210 can be adjusted manually to achieve the purpose of adjusting the angle of the photoelectric probe 500. Understandably, the angle adjustment function of the clamp assembly, coupled with the rotation avoidance of the connector 300, can increase the rotation angle range of the azimuth and pitch angles of the photothermal support, making it less prone to interference. In addition, the azimuth angle of the photoelectric probe 500 is also more selectable, which can meet the functional requirements. The structure is reasonably designed and highly practical.

[0045] Specifically, both the first clamp 711 and the second clamp 712 are made of bent and welded steel plates and are bolted to the column 700. The connector 300 is also made of bent and welded steel plates, and its first opening 340 and first rotating shaft 330 are coaxial. Thus, when the connector 300 connects the support rod 200 and the column 700, the first rotating shaft 330 and the second rotating shaft 360 can be set coaxially, thereby ensuring that when the connector 300 is rotated by external force, it will not exert a force on the fixed part 210 and thus drive the support rod 200 to rotate, further ensuring that the position of the photoelectric probe 500 remains unchanged. In another embodiment, the clamp assembly can also be an integral clamp, which is fastened at both ends by bolts after surrounding the column 700; in another embodiment, the clamp assembly can be omitted, and lugs, connecting plates, etc., that are fixedly connected to the column can be provided on the column by welding, bolting, or riveting, and then the second rotating shaft 360 can be used to assist in the rotational connection between the connector 300 and the column 700.

[0046] Preferably, see Figure 7 and Figure 8 A second bearing 715 is installed inside the third opening 714, and the second bearing 715 is sleeved on the outside of the second rotating shaft 360. At this time, a baffle 716 is provided at the bottom of the third mating part 713 corresponding to the third opening 714 to support the second bearing 715. The setting of the second bearing 715 makes it easier for the connector 300 to rotate under the action of external force, and the rotation is smooth and without jamming, with a fast response speed, which is beneficial to improving the overall performance of the photothermal support.

[0047] Further, see Figure 4 There are two clamp assemblies, which are spaced apart along the axis of the column 700. The second docking part 320 is provided with two mounting ears 350. The first opening 340 is opened on the two mounting ears 350, and the two mounting ears 350 are respectively located on the side of the two clamp assemblies that are far apart from each other. The second rotating shaft 360 passes through the two first openings 340 and the two third openings 714 to realize the rotational connection between the second docking part 320 and the base 710, so as to achieve higher structural stability.

[0048] In one example embodiment, see Figure 9 The photoelectric probe mounting structure also includes a first mounting base 410 and a second mounting base 420. The first mounting base 410 is mounted on the end of the support rod 200 away from the fixed base 100, and the second mounting base 420 is mounted on the first mounting base 410 for mounting the photoelectric probe 500. The first mounting base 410 is fixed to the end of the support rod 200 and has a first adjustment hole 413 for adjusting its azimuth angle. Fasteners pass through the first adjustment hole 413 to lock the first mounting base 410 to the support rod 200 and limit the azimuth angle of the photoelectric probe 500. Conversely, the first mounting base 410 also has a second adjustment hole 414 for adjusting the pitch angle of the second mounting base 420 relative to the first mounting base 410. Fasteners pass through the second adjustment hole 414 to lock the second mounting base 420 to the first mounting base 410 and limit the pitch angle of the photoelectric probe 500.

[0049] Specifically, the first mounting base 410 includes a first mounting plate 411 and two first support plates 412 located on opposite sides of the first mounting plate 411, making the first mounting base 410 generally U-shaped. The first mounting plate 411 has the aforementioned first adjustment hole 413 for connecting with the support rod 200. The two first support plates 412 extend away from the support rod 200 and have second adjustment holes 414 for connecting with the second mounting base 420. The second mounting base 420 includes a second mounting plate 421 and two second support plates 422 located on opposite sides of the second mounting plate, making the second mounting base 420 also generally U-shaped, with the openings of the first mounting base 410 and the second mounting base 420 facing each other. The second mounting plate 421 connects with the photoelectric probe 500, and the two second support plates 422 extend away from the photoelectric probe 500, respectively connecting with the two first support plates 412.

[0050] In this embodiment, there can be multiple first adjustment holes 413. Fasteners can be inserted into different first adjustment holes 413 to change the azimuth angle of the photoelectric probe 500. Correspondingly, there can also be multiple second adjustment holes 414. Fasteners can be inserted into different second adjustment holes 414 to change the pitch angle of the photoelectric probe 500.

[0051] Of course, in actual production, both the first adjustment hole 413 and the second adjustment hole 414 can be arc-shaped. By changing the position of the fasteners locked in the first adjustment hole 413 and the second adjustment hole 414, the azimuth and elevation angles of the photoelectric probe 500 can be adjusted. Bolts and screws are preferred as fasteners. The operator does not need to remove the fasteners; simply loosening the fasteners and moving their positions in the first adjustment hole 413 and the second adjustment hole 414 will adjust the angle of the photoelectric probe 500. After adjusting the angle, tightening the fasteners will complete the fixation, keeping the angle and position of the photoelectric probe 500 unchanged.

[0052] Preferably, the first support plate 412 has a fixing hole 415 at the arc-shaped center of the second adjustment hole 414. Fasteners pass through the fixing hole 415 to rotatably fix the second support plate 422 to the first support plate 412. By providing the fixing hole 415, it is easier to lock the photoelectric probe 500 at the required pitch angle, and it is less likely to deviate. Moreover, when the operator adjusts the pitch angle, only the corresponding fastener in the second adjustment hole 414 needs to be loosened, and the fastener in the fixing hole 415 can still connect to the second mounting base 420, which is convenient for the operator.

[0053] See Figure 1 and Figure 2 This application also provides a photothermal support, including a column 700, a drive device 600, a fixing base 100, a main shaft 801, purlins 802, a heliostat assembly 803, and the photoelectric probe mounting structure provided in any of the above embodiments. The heliostat assembly 803 is mounted on the main shaft 801 via the purlins. The drive device 600 is used to drive the main shaft 801 to rotate around its own axis or around the axis of the column 700, so as to change the pitch angle and azimuth angle of the heliostat assembly 803. There are multiple heliostat assemblies 803, and there is a gap between adjacent heliostat assemblies 803. The support rod 200 passes through the gap to mount the photoelectric probe 500 above the heliostat assembly 803.

[0054] Specifically, multiple purlins 802 are arranged sequentially on the main shaft 801, and the heliostat assembly 803 is arranged on the purlins 802. When the driving device 600 drives the main shaft 801 to rotate around its own axis, the angle positioning mechanism 300 in this embodiment includes a fixed member 210, a base 710, and a connecting member 300. The connecting member 300 is hinged to the fixed member 210 and the base 710. The fixed member 210 and the base 710 are respectively connected to the support rod 200 and the column 700 to stabilize the azimuth angle of the photoelectric probe. At this time, the rotation setting of the connecting member 300 can automatically rotate to avoid the purlins 802, providing sufficient space for the normal operation of the heliostat assembly 803, without affecting the dual-axis rotation of the photothermal support, and the support rod 200 remains stationary during this process. The structure is reasonable and practical.
