Description

Technical Field

[0001] The present application relates to the technical field of photothermal brackets, and in particular to a photoelectric probe structure and a photothermal bracket. Background Art

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

[0003] Currently, most tracking systems use astronomical algorithms, but due to construction and installation errors, tracking accuracy is low. To further improve the tracking accuracy of tower-type dual-axis heliostats, additional photoelectric sensors are installed near the heliostat's reflective mirror surface to help it reflect light more accurately. Once the photoelectric sensor angle is adjusted, it cannot be changed, so it is usually installed on the ground using additional columns. This undoubtedly increases construction workload and consumes maintenance space.

[0027] Currently, photoelectric probes are generally installed on the ground through additional columns, which increases the amount of ground construction. The columns installed on the ground will occupy operation and maintenance space, resulting in a large and unsightly site for the solar thermal power station project.

[0028] For this, see Figures 1 to 3This application provides a photoelectric probe mounting structure, which is installed on a solar thermal support. This structure can integrate the photoelectric probe 500 onto the support, eliminating the need for additional fixing structures on the ground. This eliminates the need to fix the photoelectric probe 500 to the ground, shortens the construction period, and saves labor costs. Furthermore, it effectively saves space, providing sufficient space for subsequent maintenance and cleaning of the heliostat 803, avoiding disruption to the normal operation of maintenance vehicles. This also makes the solar thermal power station project cleaner and more aesthetically pleasing.

[0029] In one 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 in the middle of the mirror surface of the heliostat assembly 803 of the CSP support. The photoelectric probe 500 is mounted on top of the support rod 200. The support rod 200 passes upward through the gap between two heliostats in the heliostat assembly 803, positioning the photoelectric probe 500 above the CSP support. The base 710 is used to secure the CSP support to the support column. The connector 300 is connected to the support rod 200 and the base 710, respectively, and is used to secure the support rod 200 to the base 710. By integrating the photoelectric probe mounting structure into the CSP support, there is no need for additional fixing structures on the ground, eliminating the need for 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 device 600, a fixing base 100, a main shaft 801, a purlin 802 and a heliostat assembly 803. The drive device 600 is installed on the top of the column 700, the fixing base 100 is fixed to the top of the drive device 600, the main shaft 801 is connected to the drive device 600 by transmission, and the heliostat assembly 803 is installed on the main shaft 801 through the purlin 802.

[0031] The driving device 600 is a dual-axis rotary driving mechanism. For details, please refer to Figure 4As shown, the drive device 600 includes a first rotating mechanism 620 and a second rotating mechanism 630. The first rotating mechanism 620 and the second rotating mechanism 630 are sequentially arranged at the top of the column 700 along the height direction of the column 700. The first rotating mechanism 620 includes a first drive motor 621, and the second rotating 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 rotating mechanism 630 is located above the first rotating mechanism 620. The main shaft 801 of the solar thermal support is drivingly connected to the power output shaft of the second rotating mechanism 630. Driven by the second drive motor 631 of the second rotating 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 rotate about the axis of the 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 rotate about the axis of the column 700, thereby adjusting the azimuth angle of the heliostat assembly 803. The fixing base 100 is provided on the second rotary mechanism 630.

[0033] The first rotary mechanism 620 also includes a first input shaft, a first transmission assembly, and a first output shaft. The first input shaft is transmission-connected to the first drive motor 621 and the first transmission assembly, respectively. The first transmission assembly is transmission-connected to the first output shaft. The power of the first drive motor 621 is sequentially transmitted to the first output shaft via the first input shaft and the first transmission assembly. The first output shaft is transmission-connected to the second rotary mechanism 630, thereby driving the second rotary mechanism 630 to rotate about 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 also includes a second input shaft, a second transmission assembly, and a second output shaft. The second input shaft is transmission-connected to the second drive motor 631 and the second transmission assembly, respectively. The second transmission assembly is transmission-connected to the second output shaft. The second output shaft is transmission-connected to the main shaft 801. Driven by the second drive motor 631, the second input shaft, the second transmission assembly, and the second output shaft rotate, thereby driving the main shaft 801 and the heliostat assembly 803 mounted on the main shaft 801 to rotate. The first transmission member group and the second transmission member group can be in the form of gear transmission, worm gear transmission, bevel gear transmission, etc.

[0034] Please continue to refer to Figure 4 and Figure 5As shown, in actual production, the top of the second rotating mechanism 630 is often curved. To ensure stable fixation of the fixing base 100 and the support rod 200, the top of the second rotating mechanism 630 may be provided with at least two raised supports 610. The top surfaces of these supports 610 are all on the same horizontal plane, providing a flat surface for the fixing base 100 to be installed, thereby improving the stability of the overall structure. The number of supports 610 is preferably four. The fixing base 100 is machined and fixed to these four raised supports 610 to support the weight of the upper photoelectric probe 500 and the support rod 200. The fixing base 100 includes a connecting portion 110 and a main body 120. The main body 120 has a hollow cavity. The connecting portion 110 is fixedly connected to the supports 610, thereby securing the fixing base 100 to the second rotating 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 be directly inserted into the fixed base 100 and rotatably connected thereto. To improve the stability and smoothness of relative rotation between the fixed base 100 and the support rod 200 and prevent the drive device 600 from affecting the support rod 200 during operation, a first bearing 122 can be further provided within the fixed base 100. This first bearing 122 is sleeved onto the exterior of the support rod 200. When the drive device 600 drives the main shaft 801 and the heliostat assembly 803 to rotate about the axis of the column 700, or about the axis of the main shaft 801, the support rod 200 does not interfere with the mirrors in the heliostat assembly 803.

[0036] Alternatively, see Figure 5 , a flange shaft 121 can also be provided at the end of the support rod 200 away from the photoelectric probe 500. The flange shaft 121 is fixedly connected to the support rod 200 and extends into the cavity of the fixing seat 100, and is rotatably connected to the fixing seat 100, thereby realizing the rotational connection between the support rod 200 and the fixing seat 100. This structure can also realize the function of the first bearing 122. At this time, in order to improve the stability and smoothness of the relative rotation between the fixing seat 100 and the support rod 200 and prevent the driving device 600 from affecting the support rod 200 during operation, a first bearing 122 can also be provided in the fixing seat 100. The 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 fixing seat 100 through the first bearing 122. One end of the flange shaft 121 passes through the fixing seat 100 and is fixedly connected to one end of the support rod 200. The support rod 200 is preferably made of a steel pipe profile and a flange welded together. 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 mount the photoelectric probe 500 .

[0037] In this embodiment, a first bearing 122 is provided to support relative rotation between the flange shaft 121 and the fixed base 100. This, in conjunction with the connector 300, ensures that when the drive device 600 drives the main shaft 801 to rotate about the axis of the column 700, only the fixed base 100 rotates horizontally with the drive device 600, while the flange shaft 121 and the support column 200 remain stationary, thereby ensuring that the position of the photoelectric probe 500 remains unchanged. Furthermore, the presence of the first bearing 122 allows the fixed base 100 to rotate more smoothly relative to the flange shaft 121 without any jamming, thus neither affecting the operation of the drive device 600 nor the support column 200.

[0038] The first bearing 122 is preferably a roller bearing having 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, and the inner ring of the bearing remains stationary, which is more conducive to ensuring that the position of the photoelectric probe 500 remains unchanged. Moreover, the roller bearing has standard dimensions, is interchangeable, and is easy to disassemble and assemble, which is conducive to mass production and use.

[0039] The first bearings 122 within the fixed base 100 also support the support rod 200 and the photoelectric probe 500. Therefore, generally speaking, the greater the number of first bearings 122, the more stable the photoelectric probe 500. In one exemplary embodiment, there are two first bearings 122, spaced apart along the height of the flange shaft 121. A sleeve 123 is also sleeved around the flange shaft 121. This sleeve 123 is positioned between the two first bearings 122 and abuts against the inner races of the first bearings 122, thereby providing upward support and restraint for the upper first bearing 122, preventing it from sliding downward. Conversely, a retaining seat 124 is mounted on the end of the flange shaft 121 away from the support rod 200. This retaining seat 124 provides upward support and restraint for both first bearings 122, preventing them from sliding downward. The arrangement of the sleeve 121 and retaining seat 124 ensures that the first bearings 122 are stably retained at their respective positions on the flange shaft 121. The flange shaft 121 is preferably a hollow structure, and the stopper 124 includes a main body 1241 and a stopper 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 provided on the circumferential outer portion of the main body 1241 and on the inner wall of the cavity of the flange shaft 121. The stopper 124 and the flange shaft 121 are fixedly connected by tightening the main body 1241. The stopper 1242 abuts against the bottom end surface of the flange shaft 121 and has an extension 1243 away from the axis of the stopper 124. The extension 1243 is located below the first bearing 122, facilitating installation while also providing a stopper for the first bearing 122 to prevent it from falling out of the fixing seat 100. It should be noted that there is a certain distance between the limit seat 124 and the outer periphery of the second rotating mechanism 630, thereby ensuring that the limit seat 124 will not be affected by the second rotating mechanism 630 during the rotation of the second rotating mechanism 630, resulting in the position of the photoelectric probe 500 changing.

[0040] Please continue to refer to 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. The ends of the connecting member 300 are respectively connected to the base 710 and the fixing member 210, thereby ensuring a relatively fixed connection between the support rod 200 and 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 achieving a defined azimuth angle of the support rod 200 and the photoelectric sensor 500 thereon.

[0041] Considering that the drive device 600 also drives the main shaft 801 to rotate about its own axis to deflect the heliostat assembly 803, during this deflection, the CSP support (e.g., the purlins 802 arranged on the main shaft 801) may interfere with the connector 300. In a preferred embodiment, the connector 300 is rotatably connected to the base 710 and the fixing member 210 at both ends. Thus, when the drive device 600 drives the main shaft 801 to rotate about its own axis, the connector 300, under the action of external forces (e.g., the purlins 802), can rotate relative to the fixing member 210 and the base 710 to provide clearance, providing sufficient space for the normal operation of the heliostat assembly 803 without affecting the CSP support's biaxial rotation. During this process, the support rod 200 remains stationary, resulting in a reasonable and practical structural arrangement.

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

[0043] Please refer to Figures 4 to 8 As shown, the base 710 includes at least one clamping assembly, which includes a first clamping member 711 and a second clamping member 712. The first clamping member 711 and the second clamping member 712 are jointly engaged with the outside of the column 700, and one of the first clamping member 711 and the second clamping member 712 is rotatably connected to the connector 300 via the second rotating shaft 360. For example, one of the first clamping member 711 and the second clamping member 712 is provided with a third docking portion 713, which has a third opening 714. The two ends of the second rotating shaft 360 are respectively inserted into the first opening 340 and the third opening 714 to achieve a rotatable connection between the second docking portion 320 and the third docking 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 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, ensuring that the position of the photoelectric probe 500 does not change. If the azimuth angle of the photoelectric probe 500 needs to be changed, the operator can also adjust the clamp assembly to change the orientation of the third docking portion 713 thereon, and then use the first rotating shaft 330 on the connector 300 to determine the orientation of the fixing member 210, thereby changing the azimuth angle of the photoelectric probe 500. This operation is convenient and quick, and helps the operator to reasonably control the angle of the photoelectric probe 500. Alternatively, the orientation of the connector 300 and the fixing member 210 can be manually adjusted to achieve the purpose of adjusting the angle of the photoelectric probe 500. It can be understood that the angle adjustment function of the clamp group, supplemented by the rotation avoidance of the connector 300, can increase the rotation angle range of the azimuth angle and the rotation angle range of the pitch angle of the photothermal bracket, is not easy to interfere, and the azimuth angle options of the photoelectric probe 500 are also more, which can meet the functional requirements, and the structural setting is reasonable and practical.

[0045] Specifically, the first clamping member 711 and the second clamping member 712 are both formed from bent and welded steel plates and are fastened to the column 700 via bolts. The connecting member 300 is also formed from bent and welded steel plates, and its first opening 340 and first rotating shaft 330 are coaxial. This ensures that when the connecting member 300 connects the support rod 200 and the column 700, the first rotating shaft 330 and the second rotating shaft 360 are coaxially arranged. This ensures that when the connecting member 300 is rotated by an external force, it does not exert force on the fixed member 210, thereby driving the support rod 200 to rotate, further ensuring that the position of the photoelectric sensor 500 remains unchanged. In another embodiment, the clamp group may be an integral clamp, which surrounds the column 700 and has its two ends fastened by bolts. In another embodiment, the clamp group may not be provided, but a lug, connecting plate, etc. fixedly connected to the column may be provided on the column by welding, bolt connection or riveting, and then assisted by the second rotating shaft 360, thereby realizing the rotational connection between the connecting member 300 and the column 700.

[0046] Preferably, see Figure 7 and Figure 8 A second bearing 715 is mounted within the third opening 714 and sleeved onto the second rotating shaft 360. A baffle 716 is provided at the bottom of the third docking portion 713, corresponding to the third opening 714, to support the second bearing 715. The provision of the second bearing 715 facilitates the connector 300's rotation in response to external forces, resulting in smooth, non-stuttering rotation and a fast response, thus improving the overall performance of the solar thermal support.

[0047] Further, see Figure 4 There are two clamping hoop groups, spaced apart along the axis of the column 700. The second docking portion 320 is provided with two mounting ears 350. The first openings 340 are formed in the two mounting ears 350, and the two mounting ears 350 are located on the sides of the two clamping hoop groups that are separated from each other. The second rotating shaft 360 is passed through the two first openings 340 and the two third openings 714 to achieve a rotational connection between the second docking portion 320 and the base 710, thereby enhancing structural stability.

[0048] In one example embodiment, see Figure 9 The photoelectric sensor 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 fixing base 100, and the second mounting base 420 is mounted on the first mounting base 410 for mounting the photoelectric sensor 500. The first mounting base 410 is fixed to the end of the support rod 200. The first mounting base 410 defines a first adjustment hole 413 for adjusting the azimuth angle of the first mounting base 410. A fastener passes 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 sensor 500. Conversely, the first mounting base 410 also defines a second adjustment hole 414 for adjusting the elevation angle of the second mounting base 420 relative to the first mounting base 410. A fastener passes through the second adjustment hole 414 to lock the second mounting base 420 to the first mounting base 410 and limit the elevation angle of the photoelectric sensor 500.

[0049] Specifically, the first mounting base 410 includes a first mounting plate 411 and first support plates 412 disposed on opposite sides of the first mounting plate 411, giving the first mounting base 410 an overall U-shaped structure. The first mounting plate 411 is provided with the aforementioned first adjustment hole 413 for docking with the support rod 200. The two first support plates 412 extend away from the support rod 200 and have second adjustment holes 414 disposed therein for docking with the second mounting base 420. The second mounting base 420 includes a second mounting plate 421 and second support plates 422 disposed on opposite sides of the second mounting plate, also forming a U-shaped structure. The openings of the first and second mounting bases 410 and 420 face each other. The second mounting plate 421 is used to dock with the photoelectric sensor 500. The two second support plates 422 extend away from the photoelectric sensor 500 and are respectively used to dock with the two first support plates 412.

[0050] In this embodiment, the number of first adjustment holes 413 can be multiple, and the azimuth angle of the photoelectric probe 500 can be changed by passing the fasteners through different first adjustment holes 413; correspondingly, the number of second adjustment holes 414 is also multiple, and the pitch angle of the photoelectric probe 500 can be changed by passing the fasteners through different second adjustment holes 414.

[0051] Of course, in actual production, the first adjustment hole 413 and the second adjustment hole 414 can both 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. The fasteners are preferably bolts, screws, etc. The operator does not need to remove the fasteners, but only needs to loosen the fasteners and move them in the first adjustment hole 413 and the second adjustment hole 414 to adjust the angle of the photoelectric probe 500. After adjusting the angle, tighten the fasteners to complete the fixation, maintaining the angle and position of the photoelectric probe 500 unchanged.

[0052] Preferably, the first support plate 412 is provided with a fixing hole 415 at the center of the arc of the second adjustment hole 414. A fastener passes through the fixing hole 415 to rotatably secure the second support plate 422 to the first support plate 412. The provision of the fixing hole 415 facilitates locking the photoelectric probe 500 at a desired pitch angle, making it less likely to shift. Furthermore, when adjusting the pitch angle, the operator need only loosen the corresponding fastener in the second adjustment hole 414. The fastener in the fixing hole 415 can still connect the second mounting base 420, thus facilitating operation.

[0053] See also Figure 1 and Figure 2 The present application also provides a solar thermal support, comprising 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 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 extends through the gap to install the photoelectric probe 500 above the heliostat assembly 803.

[0054] Specifically, a plurality of purlins 802 are arranged in sequence on the main shaft 801, and the heliostat assembly 803 is arranged on the purlin 802. When the driving device 600 drives the main shaft 801 to rotate around its own axis. Therefore, the angle positioning mechanism 300 in this embodiment includes a fixed part 210, a base 710 and a connecting part 300. The connecting part 300 is hinged to the fixed part 210 and the base 710. The fixed part 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 part 300 can automatically rotate to avoid when it encounters the purlin 802, providing sufficient space for the normal operation of the heliostat assembly 803, without affecting the dual-axis rotation of the photothermal bracket. During this process, the support rod 200 remains stationary, and the structural setting is reasonable and practical.
