Abstract
Description
Technical Field
[0001] This utility model relates to the field of photothermal technology, and in particular to a heliostat side-rolling connecting seat and a heliostat adjustment device. Background Technology
[0002] In solar thermal utilization systems, heliostats play a crucial role as key concentrating devices. The basic function of a heliostat is to reflect sunlight and precisely focus it onto a specific target; it is usually a receiver located at the top of a tower. Structurally, a heliostat mainly consists of three parts: the heliostat's reflecting structure, the support device, and the drive mechanism and tracking control system.
[0003] Currently, the driving mechanism of heliostats mainly consists of a combination of a rotary reducer and a linear drive. The rotary reducer controls the azimuth angle of the heliostat's reflecting structure, while the linear drive controls the elevation angle. However, the rotary reducer in this design is inconvenient to maintain and too expensive. Replacing the rotary reducer with a linear drive can effectively solve these problems, but the existing heliostat support device cannot be adapted to the linear drive.
[0004] Therefore, it is urgent to study a heliostat side-roll connector to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a heliostat side roll connector and a heliostat adjustment device, which, while ensuring the performance of the heliostat, not only replaces the rotary reducer drive method, but also reduces the cost of the drive components, thus facilitating the widespread use of heliostats.
[0006] To achieve the above objectives, the following technical solution is provided:
[0007] The heliostat roll-on connector includes:
[0008] A connecting seat body, the first end of which is mounted on a supporting structure;
[0009] A rotary shaft sleeve is disposed at the second end of the connecting seat body and forms an integral structure with the connecting seat body. The angle between the first axis of the rotary shaft sleeve and the XY horizontal plane is an acute angle. The rotary shaft sleeve is configured to install a rotating shaft.
[0010] A drive component connection structure is provided, which is installed on the outer wall of the connector body, and has pin holes for mounting a linear drive mechanism.
[0011] As an optional solution for the heliostat side roll connection seat, the drive component connection structure includes at least two connection supports, each of which includes a mounting part with a plate-like structure.
[0012] At least two adjacent mounting portions are parallel to each other, and each of the two adjacent mounting portions is provided with a through pin hole;
[0013] The center lines of the pin holes on two adjacent mounting parts are located on the second axis, which is parallel to the first axis of the rotary sleeve.
[0014] As an optional solution for the heliostat side-rolling connection seat, the number of the connection support is two, and the connection support as a whole has a sheet-like structure;
[0015] The two connecting supports are respectively installed on the outer wall of the connecting support body, and the two connecting supports are parallel to each other;
[0016] The pin hole is located on the side of the connecting support away from the connecting body.
[0017] As an optional solution for the heliostat side-rolling connector, the rotating shaft sleeve is welded to the connector body, or
[0018] The rotary shaft sleeve and the connecting seat body are integrally cast.
[0019] As an optional solution for the heliostat side-rolling connector, along the first axis direction, the length of the connection between the connector body and the rotary shaft sleeve is not greater than the length of the rotary shaft sleeve.
[0020] As an optional solution for the heliostat side-rolling connector, at least one side of the outer wall of the connector body is provided with a tangent plane, and the connection between the connector body and the rotary shaft sleeve is transitionally connected to the tangent plane.
[0021] As an optional solution for the heliostat side-roll connector, the heliostat side-roll connector further includes:
[0022] A reinforcing rib is provided between the drive component connection structure and the outer wall surface of the connecting seat body.
[0023] As an optional solution for the heliostat side roll connection seat, one end of the rotating shaft sleeve has a first through hole, and the other end of the rotating shaft sleeve has a second through hole, wherein the first through hole and the second through hole are connected or not connected.
[0024] As an optional solution for the heliostat side-rolling connector, the first end of the connector body is provided with an adapter flange, which is used to connect the support structure.
[0025] A heliostat adjustment device includes a heliostat pitch connection seat, a telescopic drive component, a support column, and a heliostat roll connection seat as described in any one of the above.
[0026] The first end of the connecting seat body is connected to the support column, the heliostat pitch connecting seat is rotatably connected to the heliostat roll connecting seat, the fixed end of the telescopic drive is hinged to the pin hole of the drive connecting structure, and the telescopic end of the telescopic drive is hinged to the cantilever beam on the pitch connecting seat.
[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0028] The heliostat side-roll connecting seat provided by this utility model sets the angle between the first axis of the rotary shaft sleeve and the XY horizontal plane to an acute angle, so that the heliostat's reflecting structure still has a large azimuth adjustment range after using a linear drive device instead of a rotary reducer. Furthermore, the integrated structure of the heliostat side-roll connecting seat makes it more stable and reliable. Specifically, the heliostat side-roll connecting seat mainly includes a connecting seat body, a rotary shaft sleeve, and a drive component connecting structure. The heliostat's reflecting surface structure is rotatably connected to the rotary shaft sleeve via a rotating shaft. The angle between the first axis of the rotary shaft sleeve and the XY horizontal plane is an acute angle. A pin hole is provided on the drive component connecting structure. When the fixed end of the telescopic drive component is hinged to the pin hole, and the telescopic end of the telescopic drive component is hinged to the heliostat's reflecting surface structure, the side-roll deflection angle of the heliostat can be changed by extending and shortening the telescopic drive component, ensuring the performance of the heliostat.

[0040] The embodiments of this utility model are described in detail below.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0041] To ensure the performance of the heliostat while replacing the rotary reducer drive method and reducing the overall cost of the heliostat, thus facilitating its widespread use, this embodiment provides a heliostat side-roll connecting seat and a heliostat adjustment device. The following description, in conjunction with... Figures 1 to 4 The specific content of this embodiment will be described in detail.
[0042] The heliostat roll connector 100 mainly comprises three core parts: a connector body 1, a rotary shaft sleeve 2, and a drive component connecting structure 3. The first end of the connector body 1 is mounted on a support structure; the rotary shaft sleeve 2 is located at the second end of the connector body 1 and forms an integrated structure with it. The angle between the first axis L1 of the rotary shaft sleeve 2 and the XY horizontal plane P is an acute angle, and the rotary shaft sleeve 2 is configured to mount a rotating shaft; the drive component connecting structure 3 is mounted on the outer wall of the connector body 1, and has pin holes 31 for mounting a linear drive mechanism.
[0043] In the field of solar thermal power generation, heliostats are key components, and their performance and cost directly affect the efficiency and economic benefits of the entire power generation system. The heliostat side-roll connector 100 proposed in this embodiment, with its unique and ingenious structural design, brings a brand-new solution to the driving and adjustment of heliostats. While ensuring the performance of heliostats, it significantly reduces the cost of driving components, thus strongly promoting the widespread application of heliostats.
[0044] It should be noted that the drive component connecting structure 3 is configured to mount the fixed end (or telescopic end) of the linear drive mechanism. The linear drive mechanism is mounted in the pin hole 31 on the drive component connecting structure 3 via a connecting shaft. Here, the structure of the drive component connecting structure 3 is not specifically limited. For example, the drive component connecting structure 3 may be a single integral component with pin holes 31 for mounting the linear drive mechanism, or it may be composed of multiple components. Furthermore, the shape and size of the drive component connecting structure 3 are not limited here and can be designed according to the actual application.
[0045] In an embodiment of this technical solution, the drive component connection structure 3 includes at least two connecting supports 32, each connecting support 32 including a mounting portion with a sheet-like structure; at least two adjacent mounting portions are parallel to each other, and pin holes 31 are provided through the two adjacent mounting portions; wherein, the center line of the pin holes 31 on the two adjacent mounting portions is located on the second axis L2, and the second axis L2 is parallel to the first axis L1 of the rotary shaft sleeve 2.
[0046] Specifically, see attached Figure 1-3 As shown, in the implementation of this technical solution, there are two connecting supports 32, which are generally sheet-like structures. The two connecting supports 32 are respectively installed on the outer wall of the connecting body 1, and are parallel to each other. The pin hole 31 is located on the side of the connecting support 32 away from the connecting body 1. The connecting body 1 serves as the basic support component of the entire structure, and its first end bears the important task of connecting with the support structure. The rotary shaft sleeve 2 is located at the second end of the connecting body 1, and the rotary shaft sleeve 2 and the connecting body 1 form an integrated structure. This integrated design not only enhances the overall strength and stability of the structure and reduces the risk of failure due to loose component connections, but also simplifies the installation and maintenance process, reducing construction difficulty and cost. The first axis L1 of the rotary shaft sleeve 2 is set at an acute angle to the XY horizontal plane P. It provides a specific rotation direction and angle range for the heliostat's reflecting structure, allowing the heliostat's reflecting structure to rotate flexibly within this angle range, thereby achieving precise adjustment of the heliostat (generally, enabling the heliostat to track the sun in all directions from 0° to 90°). The drive component connecting structure 3 serves as an important connecting component between the connecting seat body 1 and other parts. One end of the connecting support 32 of the drive component connecting structure 3 is tightly connected to the outer wall surface of the connecting seat body 1, and the other end of the connecting support 32 of the drive component connecting structure 3 is provided with a pin hole 31. The second axis L2 of the pin hole 31 is parallel to the first axis L1 of the rotating shaft sleeve 2. This parallel design ensures the stability and coordination of the linear drive mechanism during installation and operation.
[0047] It should be noted that the aforementioned support structure is a component used to support the heliostat side-roll connector 100. This application does not impose specific limitations on the support structure, and specific designs can be made according to actual conditions. Preferably, the support structure is a support column 400, which provides stable support for the heliostat side-roll connector 100, ensuring that the entire heliostat system can be stably installed in the designated position, resisting the effects of various natural environmental factors such as wind and earthquakes, and ensuring the safe operation of the heliostat in complex environments.
[0048] Furthermore, the linear drive mechanism is a telescopic drive component 300. When the fixed end of the telescopic drive component 300 is hinged to the pin hole 31, and the telescopic end is hinged to the heliostat pitch connection seat 200, a complete drive system is formed. The telescopic drive component 300, through its own extension and retraction movements, provides power for the heliostat's roll deflection, driving the heliostat pitch connection seat 200 to rotate around the first axis L1 of the rotating shaft sleeve 2. This changes the roll deflection angle of the heliostat's reflecting structure, ensuring that the heliostat's reflecting structure always maintains the optimal reflection angle, accurately focusing sunlight onto the collector and improving solar energy collection efficiency. By precisely controlling the extension and retraction of the telescopic drive component 300, fine-tuning of the azimuth angle of the heliostat's reflecting structure can be achieved, enabling the heliostat's reflecting structure to better track the sun's trajectory and further improve solar energy collection efficiency.
[0049] From a technical perspective, the innovative design of this heliostat side-roll connector 100 offers several advantages. First, it replaces the traditional rotary reducer drive. While the traditional rotary reducer drive can achieve precise adjustment of the heliostat, it suffers from high cost, high energy consumption, and complex maintenance. The heliostat side-roll connector 100, however, achieves heliostat adjustment through the extension and retraction of the telescopic drive component 300, resulting in a simpler structure and lower cost. For example, the telescopic drive component 300 can be hydraulic, pneumatic, or electric push rods, among other forms. These drive methods are widely used and have mature technologies in the market, offering relatively low cost and ease of maintenance and replacement. Second, it reduces the cost of drive components. By replacing the rotary reducer with the telescopic drive component 300, the overall structural complexity of the heliostat is reduced, thereby lowering the cost of the entire drive system. This can significantly reduce construction and operating costs for large-scale solar thermal power generation projects, improving economic efficiency. Finally, it facilitates the widespread adoption of heliostats. While ensuring the performance of the heliostat, the cost of the drive components has been reduced, thus enhancing the heliostat's competitiveness in the market. More companies and investors can afford the construction and operation costs of heliostats, thereby promoting the widespread application of solar thermal power generation technology. Preferably, the telescopic drive component 300 is an electric actuator.
[0050] For example, the rotary shaft sleeve 2 is welded to the connecting seat body 1. The welding process provides an extremely strong connection between the rotary shaft sleeve 2 and the connecting seat body 1. During welding, high temperatures melt the metal at the contact surfaces of the rotary shaft sleeve 2 and the connecting seat body 1, causing them to fuse together and form a single unit upon cooling. This connection method offers higher strength and rigidity compared to other connection methods such as bolted connections and riveting. In the actual operation of a heliostat, it is subjected to various complex external forces, such as wind, gravity, and the inertial force generated by the heliostat's own movement. Under long-term vibration and alternating loads, bolted connections may loosen, leading to gaps in the connection and affecting the accuracy and stability of the heliostat. While riveting provides some connection strength, the rivets may deform or break under heavy loads. Welded connections effectively avoid these problems, ensuring that the rotary shaft sleeve 2 and the connecting seat body 1 remain tightly connected, forming a stable integral structure and providing a solid structural foundation for the reliable operation of the heliostat.
[0051] For example, the rotary shaft sleeve 2 and the connecting seat body 1 are integrally cast. This integral casting process gives the rotary shaft sleeve 2 and the connecting seat body 1 structural integrity. During the casting process, the molten metal flows uniformly within the mold and cools and solidifies, ensuring that there are no gaps or weak points at the joint between the rotary shaft sleeve 2 and the connecting seat body 1. This integral structure greatly enhances the strength and rigidity of the components, enabling them to better withstand the various complex external forces encountered by the heliostat during operation. Heliostats are typically installed outdoors and need to withstand wind, gravity, and inertial forces generated by their own movement for extended periods. Traditional spliced structures are prone to loosening, deformation, or even breakage at the joints under long-term stress, severely affecting the accuracy and stability of the heliostat. The integral casting structure effectively avoids these problems; its integrity results in a more uniform stress distribution, reducing stress concentration and thus improving the fatigue resistance and service life of the components. Even in harsh natural environments, such as strong winds and heavy rain, the integrally cast rotating shaft sleeve 2 and connecting seat body 1 can maintain structural stability and ensure the normal operation of the heliostat.
[0052] In the implementation of this technical solution, along the first axis L1, the length of the connection between the connecting seat body 1 and the rotating shaft sleeve 2 is no greater than the length of the rotating shaft sleeve 2, and the width of the connection between the connecting seat body 1 and the rotating shaft sleeve 2 is no greater than the outer diameter of the rotating shaft sleeve 2. Since the length of the connection between the connecting seat body 1 and the rotating shaft sleeve 2 along the first axis L1 is no greater than the length of the rotating shaft sleeve 2, if the length of the connection is too large, it may cause structural interference between the connection and surrounding components, thus affecting the rotational flexibility of the heliostat. Because the width of the connection between the connecting seat body 1 and the rotating shaft sleeve 2 does not exceed the outer diameter of the rotating shaft sleeve 2, in the actual operation of the heliostat, the reflecting structure of the heliostat needs to continuously adjust its angle to track the movement trajectory of the sun. This requires the reflecting structure of the heliostat to be able to rotate freely around the first axis L1 of the rotating shaft sleeve 2. If the width of the connection is too large, the heliostat's reflecting structure may collide or rub against the connecting seat body 1 during rotation, affecting the rotational flexibility of the heliostat's reflecting structure and even causing damage. For example, when the heliostat's reflecting structure rotates to a certain angle, an excessively wide connection may obstruct its movement path, preventing it from reaching the expected adjustment angle and thus affecting solar energy collection efficiency. Furthermore, structural interference may generate additional vibration and noise, reducing the heliostat's operational stability and reliability. Long-term structural interference may also lead to accelerated wear at the connection points, shortening the service life of the heliostat's side-rolling connecting seat 100. Therefore, reasonably controlling the width of the connection to avoid structural interference is crucial for ensuring the normal operation of the heliostat and extending its service life.
[0053] Furthermore, at least one side of the outer wall of the connecting seat body 1 is provided with a cutting plane 11, and the connection between the connecting seat body 1 and the rotary shaft sleeve 2 is smoothly connected to the cutting plane 11. This transition connection needs to be smooth and continuous to ensure that the stress can be evenly distributed at the connection and to avoid stress concentration. In the manufacturing process, high-precision machining processes, such as CNC milling, are usually used to achieve a precise transition between the connection and the cutting plane 11. By precisely controlling the tool path and cutting parameters, the transition area between the connection and the cutting plane 11 can be made smooth and without sharp edges, thereby reducing the risk of fatigue damage caused by stress concentration and improving the service life of the connecting seat body 1.
[0054] Within the rotation range of the heliostat's reflecting structure's roll deflection angle, a flat surface is removed from each side of the connecting seat body 1. This operation also requires precise geometric calculations and machining control. Designers need to accurately determine the position and size of the removed flat surfaces based on the specific dimensions of the heliostat's reflecting structure, its rotation range, and its relative positional relationship with other components. During machining, it is essential to ensure that the removed flat surfaces are flat and perpendicular to guarantee that the connecting seat body 1 meets functional requirements while possessing good appearance quality and structural stability. Specifically, in this embodiment, within the rotation range of the heliostat's reflecting structure's roll deflection angle, a flat surface is removed from each side of the connecting seat body 1. During the operation of the heliostat, the reflecting structure needs to roll deflect around the rotation axis sleeve 2 to track the sun's trajectory. If the outer wall surface of the connecting seat body 1 is a complete cylindrical surface or other irregular shape, it may interfere with the connecting seat body 1 during the deflection of the heliostat's reflecting structure, affecting the normal rotation of the heliostat's reflecting structure. By removing a flat surface from each side of the connecting seat body 1, more space is provided for the rotation of the heliostat's reflecting structure, effectively avoiding interference between the heliostat's reflecting structure and the connecting seat body 1. This design also cleverly reduces the distance between the connecting seat body 1 and the rotating shaft sleeve 2. In the heliostat's transmission system, the telescopic drive component 300 is used to drive the heliostat's reflecting structure to perform lateral roll deflection. The reduction in the distance between the connecting seat body 1 and the rotating shaft sleeve 2 means that the telescopic drive component 300 requires a correspondingly smaller amount of extension when driving the heliostat's reflecting structure to rotate. A smaller amount of extension not only reduces the load on the telescopic drive component 300, reducing its wear and the probability of failure, and improving the reliability and stability of the transmission system, but also makes the structure of the telescopic drive component 300 more compact, facilitating installation and maintenance. Removing a flat surface from each side of the connecting seat body 1 significantly reduces the amount of steel used in the connecting seat body 1. Steel is one of the main materials in heliostat manufacturing, and its cost accounts for a considerable portion of the total cost of the heliostat. By reducing the volume of the connector body 1, the amount of steel used is directly reduced, thereby lowering raw material costs. Furthermore, the reduction in steel consumption brings other cost savings. On the one hand, it reduces steel procurement costs; on the other hand, during processing, the reduced material volume leads to lower processing time and energy consumption, further reducing manufacturing costs. Simultaneously, the smaller connector body 1 is more convenient for transportation and installation, reducing transportation and installation costs and difficulties.
[0055] Furthermore, at least two connecting supports 32 are spaced apart on the outer wall of the connecting seat body 1. The axes (i.e., center lines) of the pin holes 31 on the two connecting supports 32 coincide to form a straight line, which is crucial to ensuring the normal operation of the telescopic drive component 300. In this embodiment, there are two identical connecting supports 32 on the connecting seat body 1. The two identical connecting supports 32 are engaged with the telescopic drive component 300 using pins (i.e., connecting shafts) to form a stable transmission structure. The telescopic drive component 300 transmits power to the heliostat's reflecting structure through its telescopic movement, thereby achieving a change in the roll deflection angle of the heliostat's reflecting structure. When the telescopic drive 300 extends, the telescopic end of the telescopic drive 300 generates an outward thrust, which pushes the heliostat on the heliostat pitch connection 200 to rotate around the rotary shaft sleeve 2 on the connection body 1, thereby increasing the roll deflection angle of the heliostat's reflecting structure. When the telescopic drive 300 shortens, the telescopic end of the telescopic drive 300 generates an inward pull, which causes the heliostat's reflecting structure on the heliostat pitch connection 200 to rotate in the opposite direction, thereby decreasing the roll deflection angle of the heliostat's reflecting structure.
[0056] In another embodiment of this technical solution, one end of the rotating shaft sleeve 2 has a first through hole 21, and the other end of the rotating shaft sleeve 2 has a second through hole 22. The first through hole 21 and the second through hole 22 may or may not be connected. These two different design methods provide a flexible and reliable solution for the rotational connection of the heliostat. Preferably, the center line of the first through hole 21 and the center line of the second through hole 22 are on the same straight line.
[0057] For example, when the first through hole 21 and the second through hole 22 are connected, the internal channel of the rotary shaft sleeve 2 is in a through state. With this design, only one rotary shaft needs to be inserted through the rotary shaft sleeve 2 and the heliostat pitch connector 200 to achieve a rotational connection between the heliostat pitch connector 200 and the heliostat roll connector 100. The single-axis insertion design greatly simplifies the rotational connection structure of the heliostat. Reducing the number of rotary shafts means reducing the number of parts and lowering assembly complexity. Furthermore, the single-axis insertion design facilitates maintenance and upkeep. When the rotary shaft needs repair or replacement, only one rotary shaft needs to be handled, making the operation more convenient and faster. Moreover, due to the simple structure, maintenance personnel can more easily diagnose the cause of the fault and perform repairs, reducing maintenance costs and time.
[0058] For example, when the first through hole 21 and the second through hole 22 are not connected, the internal channel of the rotating shaft sleeve 2 is not through. In this case, two rotating shafts need to be inserted through the rotating shaft sleeve 2 and the heliostat pitch connection seat 200 to achieve a rotational connection between the heliostat pitch connection seat 200 and the heliostat roll connection seat 100. This dual-axis insertion design has significant advantages in terms of stability. The two rotating shafts each bear a portion of the load and torque, making the entire rotational connection structure more stable. During the operation of the heliostat, it is subjected to various complex external forces such as wind and gravity. The dual-axis insertion can better disperse these external forces, reduce the pressure on a single rotating shaft, and reduce the risk of deformation or damage to the rotating shaft. In terms of load-bearing capacity, the dual-axis insertion design can withstand greater loads. When the heliostat is large or the operating environment is harsh, a higher load-bearing capacity is required to ensure the normal operation of the heliostat. By increasing the number of rotating shafts, the dual-axis insertion increases the load-bearing limit of the entire rotational connection structure, ensuring that the heliostat can work stably under various working conditions. In terms of precision control, the dual-axis insertion system can achieve more precise rotation control by adjusting the position and fit of the two rotating axes separately. Although the structure is relatively more complex, precise manufacturing and assembly processes can ensure the coordinated work between the two rotating axes, making the pitch and roll movements of the heliostat smoother and more accurate.
[0059] The two different through-hole designs each have their applicable scenarios. The design with a continuous internal channel and single-axis through-hole is suitable for applications where structural simplicity, transmission efficiency, and cost are critical, such as some small or medium-sized heliostat systems, or in situations with relatively stable operating environments and low loads. The design with a non-continuous internal channel and double-axis through-hole is more suitable for large heliostat systems or applications with harsh operating environments and high loads, providing higher stability and load-bearing capacity. In practical applications, the most suitable through-hole design for the rotating shaft sleeve 2 needs to be selected based on a comprehensive consideration of factors such as the specific specifications of the heliostat, the operating environment, and the cost budget. In summary, the design of whether the first through-hole 21 at one end of the rotating shaft sleeve 2 is connected or not, and the corresponding single-axis or double-axis through-hole schemes, provides diverse options for the rotational connection of the heliostat. These two designs each have their advantages and disadvantages in terms of structural simplicity, transmission efficiency, stability, and load-bearing capacity; through reasonable selection and application, the needs of different heliostat systems can be met.
[0060] Furthermore, the heliostat side-roll connecting seat 100 also includes a reinforcing rib 4, which is disposed between the drive component connecting structure 3 and the outer wall of the connecting seat body 1. The drive component connecting structure 3 consists of two connecting supports 32. The reinforcing rib 4 is configured to strengthen the structural strength of the two connecting supports 32 and ensure the parallelism between them. The reinforcing rib 4 typically adopts a structure with a specific geometric shape, such as a triangle or trapezoid. Triangular reinforcing ribs 4 are widely used due to their good stability and ability to effectively distribute stress. During the operation of the heliostat, the heliostat side-roll connecting seat 100 is subjected to various forces, including the weight of the heliostat body, wind force, and forces generated by the drive mechanism. These forces can cause bending and torsional deformation of the drive component connecting structure 3, thus affecting the stability and service life of the connecting seat. The reinforcing rib 4 significantly improves the bending and torsional resistance of the connecting seat. When the drive component connecting structure 3 is subjected to external forces, the reinforcing rib 4 acts as an additional support structure, sharing the bending and torque borne by the drive component connecting structure 3. By transferring stress from the drive component connecting structure 3 to the connecting seat body 1, the reinforcing rib 4 reduces the stress concentration of the drive component connecting structure 3, lowering the risk of breakage or deformation. For example, in strong winds, the wind exerts a large lateral force on the mirror body, which is then transferred to the heliostat roll connecting seat 100. The reinforcing rib 4 effectively resists this lateral force, maintaining a stable structural shape and ensuring the mirror body can properly track the sun's trajectory. Furthermore, the reinforcing rib 4 increases the connection stiffness between the drive component connecting structure 3 and the connecting seat body 1. Increased connection stiffness means that the relative displacement between the drive component connecting structure 3 and the connecting seat body 1 decreases under stress, thereby improving the overall accuracy and stability of the connecting seat. This is particularly important for heliostats, as even small displacement deviations can lead to inaccurate sun tracking and affect solar energy collection efficiency. The reinforcing rib 4 significantly extends the service life of the heliostat roll connecting seat 100. Because the reinforcing rib 4 improves the strength and stability of the connector, it reduces deformation and damage to the drive component connection structure 3 and the connector body 1, thus lowering the failure rate caused by structural fatigue. During long-term use, frequent maintenance and replacement are unnecessary, thereby reducing maintenance costs and downtime.
[0061] Furthermore, a transition flange 5 is provided at the first end of the connecting seat body 1. The transition flange 5 is used to connect to the support structure (e.g., the support column 400). The transition flange 5 is made of high-strength metal material, such as cast steel or alloy steel, to ensure sufficient load-bearing capacity and fatigue resistance. Multiple bolt holes are evenly distributed along the edge of the transition flange 5, ensuring that the transition flange 5 can mate with the flange on the support column 400. In this embodiment, the main function of the transition flange 5 is to connect the connecting seat body 1 and the support column 400, achieving a stable connection between them. By tightly connecting the transition flange 5 to the flange on the support column 400 with bolts, a strong connection node is formed, ensuring the accurate installation position of the heliostat body. In windy environments, the heliostat is subjected to significant wind loads. The stable connection of the transition flange 5 effectively resists the wind force on the connecting seat body 1, preventing the connecting seat body 1 from shaking or deforming. This helps maintain the stability of the heliostat, reduces mirror reflection errors caused by wind, and ensures that the heliostat can still operate normally under adverse weather conditions.
[0062] This embodiment also provides a heliostat adjustment device, which includes a heliostat pitch connection seat 200, a telescopic drive component 300, a support column 400, and the aforementioned heliostat roll connection seat 100. The first end of the connection seat body 1 is connected to the support column 400. The heliostat pitch connection seat 200 is rotatably connected to the rotary shaft sleeve 2. The fixed end of the telescopic drive component 300 is hinged to the pin hole 31 of the drive component connection structure 3, and the telescopic end of the telescopic drive component 300 is hinged to the cantilever beam 201 of the pitch connection seat. As a key component of the heliostat, the heliostat adjustment device is composed of the heliostat pitch connection seat 200, the telescopic drive component 300, the support column 400, and the heliostat roll connection seat 100. The components work closely together to achieve flexible movement and precise positioning of the heliostat in the pitch and roll directions. The precise control of the telescopic drive component 300 allows the heliostat to adjust the mirror angle in real time according to the position of the sun, efficiently reflecting sunlight onto the collector. This precise angle adjustment capability greatly improves the efficiency of solar energy collection, providing a stable and efficient energy input for solar thermal power generation systems.
[0063] It should be noted that the reflecting structure of the heliostat in this application is a component (i.e., including the heliostat pitch connecting seat 200 and other structures) mounted on the heliostat side roll connecting seat 100.
