Summary of the Invention

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a pentagonal heliostat transport system and transport device that can achieve stable transport of the entire pentagonal heliostat.

[0023] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0024] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0025] The terms “a,” “one,” “the,” and “” are used to indicate the existence of one element / component / etc.; the terms “include” and “have” are used to indicate an open-ended meaning of inclusion and that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” etc. are used only as markers and are not a limitation on the number of objects.

[0026] In tower-type concentrated solar power (CSP) plants, heliostats are the core equipment for achieving efficient solar energy collection. Currently, heliostats in tower-type CSP plants mainly include rectangular heliostats and pentagonal heliostats. Among them, the pentagonal "monster-like" heliostat, due to its more circular shape, can effectively reduce shading between mirror surfaces and reflect light more accurately, and is gradually being promoted and applied.

[0027] The pentagonal "monster lizard" heliostat is characterized by its large size and weight as a single mirror. It is about 2 meters high and weighs about 1.2 tons. The reflecting surface is pentagonal, and the diameter of the circumscribed circle can reach 9 meters. It is usually composed of 10 right-angled trapezoidal mirrors and one small central pentagonal mirror. The load-bearing center on its back has a mounting connector.

[0028] The transfer devices in related technologies are mainly used for the transfer of rectangular heliostats, and cannot achieve stable transfer of pentagonal heliostats.

[0029] To address the aforementioned issues, this disclosure provides a pentagonal heliostat transport system, comprising a transport device (not shown in the figure) and a transport apparatus, wherein the transport apparatus is attached to the transport device and is used to fix the pentagonal heliostat.

[0030] In one embodiment of this disclosure, the transfer equipment can be a transfer vehicle or similar structure.

[0031] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 1 The transfer device includes an installation platform 1 and a connecting and fixing structure 2. The connecting and fixing structure 2 is set on the installation platform 1 and is used to install and fix the pentagonal heliostat. The installation platform 1 provides stable support for the connecting and fixing structure 2 and the heliostat.

[0032] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 1 and Figure 2 The installation platform 1 can be a truss structure welded from structural steel (such as I-beams or channel steel) or a solid steel plate structure. The front end of the installation platform 1 has a hanging structure 12. Specifically, the installation platform 1 has a platform structure 11, a hanging structure 12, and a wheel assembly.

[0033] Optionally, the platform structure 11 includes a first connecting plate 111, a second connecting plate 112, a central shaft 113, multiple connecting rods 114, a first link group, a second link group, and a third link group. The first link group includes two first links 115, the second link group includes two second links 116, and the third link group includes two third links 117.

[0034] In this example, each connecting rod 114 is sequentially welded to the central shaft 113 along its extension direction. Two first connecting rods 115 are distributed on both sides of the connecting rod 114, and are welded to the two front connecting rods 114, with their extension lines intersecting. Two third connecting rods 117 are distributed on both sides of the connecting rod 114, and are welded to the rear connecting rods 114, with their extension lines intersecting. Two second connecting rods 116 are distributed on both sides of the connecting rod 114, and are welded to the outer side of the first connecting rod 115, the middle connecting rods 114, and the inner middle of the third connecting rods 117, respectively. The included angle between the extension lines of the two second connecting rods 116 is greater than the included angle between the extension lines of the two third connecting rods 117.

[0035] In this example, the first connecting plate 111 and the second connecting plate 112 are sequentially welded to the third connecting rod 117 and the central shaft 113 along the axial direction of the central shaft 113, and the first connecting plate 111 and the second connecting plate 112 are distributed on both sides of the traveling shaft 13 of the traveling wheel, with a gap between the first connecting plate 111 and the second connecting plate 112.

[0036] Of course, in other embodiments, the platform structure 11 may also adopt other structures not shown.

[0037] In this example, one end of the mounting structure 12 is welded to the front end of the platform structure 11 (in this disclosure, the front end of the platform structure 11 refers to the side where the first connecting rod 115 is provided), and the other end has a connection port. In this example, the connection port can be a mounting hole for mounting transfer equipment.

[0038] In this example, the wheels are located at the rear end of the platform structure 11.

[0039] In one embodiment of this disclosure, the mounting connector can be a disc structure with bolt holes or a mounting flange.

[0040] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 3 The connecting and fixing structure 2 includes a fixing pipe 21 and a fixing flange 22. The fixing flange 22 is used to connect with the mounting connectors on the heliostat (it can be understood that the fixing flange 22 is adapted to the mounting connectors, and the connection between the fixing flange 22 and the mounting connectors can be achieved using bolts). In this disclosure, the use of the fixing flange 22 to connect with the mounting connectors on the heliostat enables precise alignment and reliable fixing of the heliostat and the transfer device, significantly improving transfer efficiency and positioning accuracy.

[0041] In this example, one end of the fixing pipe 21 is vertically welded to the side of the first connecting plate 111 near the second connecting plate 112, while the other end is left unattended. (Setting the fixing pipe 21 on the side of the first connecting plate 111 near the second connecting plate 112 ensures the balance of the entire transfer device and utilizes the gap between the first connecting plate 111 and the second connecting plate 112 to avoid interference between other structures of the heliostat and the transfer device.) The outer diameter of the fixing pipe 21 is smaller than the outer diameter of the fixing flange 22. The fixing flange 22 is fitted and welded to the outside of the fixing pipe 21, thus forming a welded structure between the fixing flange 22 and the fixing pipe 21.

[0042] See Figure 3 The distance between the fixed flange 22 and the first connecting plate 111 on the side closer to the first connecting plate 111 is less than the height of the fixed pipe 21 (where the height of the fixed pipe 21 refers to the distance between the fixed pipe 21 and the first connecting plate 111 on the side farther away from the first connecting plate 111). In this way, part of the fixed pipe 21 will protrude from the fixed flange 22. When the fixed flange 22 is connected to the mounting connector, the fixed pipe 21 protruding from the fixed flange 22 can be inserted into the mounting connector. Firstly, this can achieve quick positioning of the fixed flange 22 and the mounting connector. Secondly, when transporting the heliostat in a strong wind environment, the fixed pipe 21 inserted into the mounting connector can be used to limit the heliostat to a certain extent, avoiding displacement of the connection between the mounting connector and the fixed flange 22 caused by strong winds, thus ensuring the stability of the heliostat during transport.

[0043] In this disclosure, taking the mounting connector of the heliostat as the starting point, a transfer device is designed for the pentagonal heliostat that needs to be transported as a whole (the transfer device in this disclosure can realize the whole-face transport of the pentagonal heliostat without affecting the installation accuracy and focusing efficiency of the heliostat in subsequent use). The fixed flange 22 is detachably connected to the mounting connector on the heliostat, which can realize the quick installation and quick disassembly of the transfer device and the heliostat. The fixed tube 21 is inserted into the mounting connector to ensure the stability of the heliostat during the transport process.

[0044] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 1 and Figure 3 The fixed pipe 21 is located between the two traveling wheels and on the center line of the mounting platform 1. This ensures the balance of the entire transfer device.

[0045] In one embodiment of this disclosure, the distance between the end of the fixing tube 21 furthest from the mounting platform 1 and the end of the fixing flange 22 furthest from the mounting platform 1 is greater than the thickness of the mounting connector. This allows more fixing tubes 21 to pass through the mounting connector and be inserted into the heliostat, further ensuring the stability of the heliostat under swaying conditions.

[0046] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 4 Both the fixed flange 22 and the mounting connector (not shown in the figure) have multiple bolt holes 26. The fixed flange 22 and the mounting connector are fixedly connected by bolts. In this disclosure, a transfer device is designed with the mounting connector of the heliostat as the starting point. By utilizing the fixed connection between the fixed flange 22 of the transfer device and the mounting connector of the heliostat, the transfer device can reliably fix the heliostat. Furthermore, the multi-point bolt connection between the fixed flange 22 of the transfer device and the mounting connector of the heliostat can reduce the risk of the heliostat shaking, slipping, or being damaged during the transfer process. In addition, the rapid positioning and fixing of the fixed flange 22 and the mounting connector can reduce manual intervention during the transfer process (manual intervention is only required for bolt fixing), without affecting the subsequent installation accuracy and focusing efficiency of the heliostat.

[0047] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 3 and Figure 4The fixed flange 22 is provided with multiple first positioning structures 23, and the mounting connector has a second positioning structure adapted to each of the first positioning structures 23. The first positioning structures 23 are used to lock with the second positioning structures. The number of first positioning structures 23 is less than the number of bolt holes 26 on the fixed flange 22. The provision of the first positioning structures 23 and the second positioning structures can further achieve rapid positioning of the fixed flange 22 and the mounting connector. Furthermore, since the bolt holes 26 are relatively large compared to the bolt size, fixing the fixed flange 22 and the mounting connector requires a longer time for positioning. In this disclosure, the locking of the first positioning structures 23 and the second positioning structures can be used to quickly align and position the bolt holes 26 of the fixed flange 22 and the bolt holes 26 of the mounting connector. In this example, there are three first positioning structures 23, evenly distributed along the circumference.

[0048] In one example, the first positioning structure 23 can be a positioning pin, and the second positioning structure can be a positioning hole. In this disclosure, the fixing tube 21 is first inserted into the mounting connector for preliminary positioning, and then the positioning pin is inserted into the positioning hole to achieve final positioning. This can increase the transport efficiency of the heliostat.

[0049] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 3 The connecting and fixing structure 2 also includes multiple reinforcing plates 24; each reinforcing plate 24 is arranged around the fixing pipe 21 and is located between the fixing flange 22 and the first connecting plate 111. Specifically, the first side of the reinforcing plate 24 is welded to the end of the fixing flange 22 near the first connecting plate 111 and to the welding structure between the fixing flange 22 and the fixing pipe 21; the second side of the reinforcing plate 24 is welded to the first connecting plate 111; and the third side of the reinforcing plate 24 is welded to the fixing pipe 21. In this disclosure, the reinforcing plates 24 can increase the supporting strength of the entire connecting and fixing structure 2 and enhance the stability and structural rigidity of the weld between the fixing flange 22 and the fixing pipe 21, so that the entire heliostat can be supported by a single connecting and fixing structure 2.

[0050] In one embodiment of this disclosure, the welding between the reinforcing plate 24 and the fixed flange 22, the welding between the reinforcing plate 24 and the fixed pipe 21, the welding between the reinforcing plate 24 and the mounting platform 1, and the welding between the reinforcing plate 24 and the welding structure are all performed at a 45-degree angle. Based on the structure of the pentagonal heliostat and the structure of the transfer device in this disclosure (using the fixed pipe 21 and the fixed flange 22 to support and fix the heliostat), when supporting and fixing the heliostat (or transferring the heliostat), it is necessary to laterally distribute the weight of the heliostat borne by the connecting and fixing structure 2 to ensure the balance of the entire transfer system and improve the service life of the entire transfer system. In this disclosure, the 45-degree welding design can achieve this function. In addition, the 45-degree welding design allows the reinforcing plate 24 to effectively distribute the stress and torque during the transfer process, ensuring the stability and safety of the connection node between the heliostat and the transfer device under the dynamic load of the transfer, and effectively preventing the heliostat from overturning or being damaged.

[0051] In one embodiment of this disclosure, the reinforcing plate 24 is made of steel.

[0052] In one embodiment of this disclosure, the reinforcing plate 24 is a right-angled trapezoid. The right-angled trapezoidal structure of the reinforcing plate 24 better achieves lateral weight distribution of the heliostat, further ensuring the balance of the entire transport system and improving its service life.

[0053] In one embodiment of this disclosure, there are four reinforcing plates 24, which are evenly distributed along the circumference of the fixed pipe 21. The ratio of the length of the first side, the length of the third side, and the length of the second side of the reinforcing plate 24 is 9:44:19. The length of the first side of the reinforcing plate 24 refers to its length along the radial direction of the fixed flange 22. The length of the second side of the reinforcing plate 24 refers to its length along the radial direction of the fixed flange 22. The length of the third side of the reinforcing plate 24 refers to its height.

[0054] In one embodiment of this disclosure, at least two adjacent reinforcing plates 24 are fixedly connected by a connecting ring 25, and the connecting ring 25 is welded to the mounting platform 1, thereby forming a storage cavity between the connecting ring 25, the two adjacent reinforcing plates 24, and the fixing pipe 21. In this disclosure, bolts are used to fix the fixing flange 22 to the mounting connector. The provided storage cavity can be used to place the bolts, avoiding the loss of bolts in extreme weather (such as strong winds), and avoiding the need to retrieve bolts repeatedly, thus improving the transport efficiency of the heliostat.

[0055] In this example, any two adjacent reinforcing plates 24 are welded together by a connecting ring 25.

[0056] In one embodiment of this disclosure, the mounting platform 1 has binding structures 3 on all four sides, which are used to bind to the periphery of the heliostat's load-bearing structure. This further secures the transport device to the heliostat during transport, reducing the amplitude of heliostat swaying in windy conditions and ensuring stability during the transport process.

[0057] In one embodiment of this disclosure, a buffer pad (not shown in the figure) is provided on the platform structure 11. This further prevents damage to the heliostat's mirror surface due to contact with the platform structure 11. In this example, the buffer pad can be a rubber pad, a polyurethane pad, or a similar structure. Of course, the buffer pad can be provided locally or throughout the platform structure 11; this disclosure does not limit this.

[0058] The welding in this disclosure uses continuous fillet welds, which can improve strength and support performance.

[0059] The transfer system proposed in this disclosure has a simple structure, low cost, and is easy to manufacture. It can also avoid contact between the mirror surface of the heliostat and the transfer system, thus avoiding damage to the mirror surface during the transfer process. In addition, this disclosure can achieve the transfer of heliostats of different sizes by replacing the fixed flange 22, or the fixed flange 22 and the fixed pipe 21, etc., which is low-cost and conducive to the promotion and use in engineering.

[0060] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
