Description

Technical Field

[0001] The utility model belongs to the technical field of heliostats, and in particular relates to a single-side open main beam for installing a heliostat frame. Background Art

[0002] In solar thermal power generation systems, heliostats are crucial devices for focusing sunlight, and their design directly impacts system performance and cost. Current mainstream heliostat designs include not only the mirrors that reflect sunlight, but also a drive mechanism, a mirror frame, and support brackets connecting the columns to the frame. The frame supports the mirrors and ensures wind resistance and surface accuracy. A typical heliostat truss consists of a main beam, trusses, and purlins, with the main beam providing primary support and preventing wind deformation.

[0003] Conventional main beams are designed as long tubular structures to support trusses distributed parallel to the width of the heliostat. Therefore, the main beams are usually designed to be long, with a length-to-diameter ratio even exceeding 50:1. This design introduces several problems: First, due to the excessive length of the main beam, the processing difficulty increases significantly, and manufacturing costs also increase accordingly. Second, controlling the tolerance of the main beam becomes very difficult, affecting the overall assembly accuracy and efficiency of the heliostat. In addition, the existing main beam structure is generally biased towards one side of the support point, resulting in poor symmetry and a large offset of the center of gravity relative to the support point. When driving the heliostat, the push rod needs to output a large amount of power to overcome this center of gravity offset, further increasing the cost and energy consumption of the system.

[0004] Therefore, the existing heliostat design has obvious shortcomings in terms of high main beam processing cost, poor structural symmetry and high driving power requirement, and urgently needs to be improved to improve overall performance and reduce costs. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application proposes a single-side open main beam for installing a heliostat frame.

[0006] In order to achieve the technical purpose of this utility model, this utility model will adopt the following technical solutions:

[0007] A single-side open main beam for mounting a heliostat mount comprises a main beam body, an upper flange, and a lower flange. The main beam body comprises two spaced-apart arcuate structures connected by a connecting beam on one side and forming an opening on the other side, the opening area providing movement space for a heliostat support seat. The inner sides of the two arcuate structures are reinforced by spaced-apart connecting plates, thereby forming two semi-cylindrical structures. The connecting plates are located on either side of the opening and are used to connect to the heliostat support seat. An upper flange and a lower flange are respectively provided at the upper and lower ends of the main beam body. A plurality of fixing positions for securing the heliostat truss are respectively provided on the upper and lower flanges.

[0008] Furthermore, the two semi-cylindrical structures are symmetrically arranged, and the inner side planes thereof formed by the connecting plates are parallel to each other.

[0009] Furthermore, the single-side open main beam also includes a main beam connector, which is a long strip structure installed laterally on the upper flange and spans the tops of the two semi-cylindrical structures.

[0010] Furthermore, a plurality of limiting grooves for positioning and limiting the installation of the heliostat truss are symmetrically distributed along the outer edges of the lower surface of the upper flange and the upper surface of the lower flange.

[0011] Furthermore, a heliostat truss mounting hole is provided in each of the limiting grooves.

[0012] Furthermore, the single-side open main beam also includes a support ear, which is symmetrically arranged at the bottom of the lower flange and is used to connect the driving mechanism of the support seat.

[0013] Furthermore, the depth, width and length of the limiting groove match the fixing components of the heliostat truss.

[0014] Furthermore, the inner planes of the two semi-cylindrical structures are respectively provided with a pin hole, and the pin hole is connected to the heliostat support seat.

[0015] Furthermore, the geometric center of the single-side open main beam is located on the longitudinal center axis of the main beam body and is located at the midpoint between the upper flange and the lower flange.

[0016] Furthermore, the rotation center axis of the heliostat support seat is perpendicular to the longitudinal center axis of the main beam body and is located above the geometric center of the main beam.

[0017] The beneficial effects of the utility model are:

[0018] First, the single-sided open main beam of the present invention achieves weight reduction and improved material utilization through the combination of the single-sided open design, the curved structure, and the connecting beam, while also reducing manufacturing and transportation costs. The design of the upper and lower flanges enables the heliostat trusses and support bases to be quickly and securely installed on the main beam body. The heliostat trusses are distributed in a diffuse manner around the outer edge of the main beam, further enhancing the stability and load-bearing capacity of the overall structure. The two curved structures provide high-strength support, ensuring the stability of the heliostats under external loads, and guaranteeing their precise positioning and long service life.

[0019] Second, in a preferred implementation, the present invention forms a semi-cylindrical structure by arranging connecting plates on the inner sides of the two arc-shaped structures, and symmetrically arranging the two semi-cylindrical structures. This can effectively improve the overall rigidity and stability of the main beam, making it stronger when bearing external loads, thereby enhancing the load-bearing capacity of the heliostat system.

[0020] Third, in the preferred implementation, the main beam connector of the present invention is installed transversely between the two semi-cylindrical structures, which effectively enhances the rigidity of the main beam, prevents the main beam from deforming under load or external force, improves the overall stability of the system, and ensures the stability of the heliostat truss during operation.

[0021] Fourth, in a preferred embodiment, the retaining grooves provided on the outer edges of the upper and lower flanges of the present invention are used to precisely position and limit the installation of the heliostat truss, ensuring a simpler and more accurate installation process while also increasing safety and reliability. The depth, width, and length of the retaining grooves match the fixing components of the heliostat truss, ensuring a smooth and efficient installation process.

[0022] Fifth, in a preferred implementation, the rotation center axis of the heliostat support of the present invention is perpendicular to the longitudinal center axis of the main beam and is located above the geometric center of the main beam. This design of the rotation center being close to the geometric center can effectively reduce the torque applied to the main beam during rotation and reduce the risk of structural deformation due to eccentric loading. Under the action of the driving torque, the main beam can more efficiently distribute the force to each support point, reduce local stress concentration, make the force distribution during rotation more uniform, and optimize the dynamic balance performance of the system during rotation.

For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] Example 1

[0034] As the instruction manual Figure 1-2The present invention describes a single-sided open main beam for mounting a heliostat frame, comprising a main beam body 1, and an upper flange 2 and a lower flange 3 for mounting a heliostat truss. The main beam body 1 comprises two spaced-apart arc-shaped structures, which are connected on one side by a connecting beam 11 and form an opening on the other side. The opening area is used to provide movement space for the heliostat support seat, ensuring flexibility in installation and operation. The inner sides of the two arc-shaped structures are reinforced by spaced-apart connecting plates 12, thereby forming two semi-cylindrical structures. The two connecting plates 12 are respectively located on both sides of the opening and are used to connect to the heliostat support seat to form a stable support structure. An upper flange 2 and a lower flange 3 are respectively provided at the upper and lower ends of the main beam body 1, and a number of fixing positions for fixing the heliostat truss are respectively arranged around the upper flange 2 and the lower flange 3.

[0035] In the embodiment of the present application, the inner connecting plates 12 of the two semi-cylindrical structures are each provided with a pin hole 10, which is connected to the heliostat support base. Preferably, the center of each pin hole 10 and the center of the corresponding semi-cylindrical structure are both located on the connecting plate 12 and coincide with each other in the longitudinal direction. The support base is mounted within the pin hole 10 via a pin.

[0036] The single-side open main beam also includes two lugs 4, each symmetrically located at the bottom of the lower flange 3, on the side opposite the opening. These lugs 4 are used to connect to the support base's drive mechanism. Both the upper and lower flanges 2 and 3 are equipped with mounting holes for the heliostat truss, symmetrically distributed around the flange's circumference to ensure symmetrical force during installation.

[0037] As the instruction manual Figure 3 , Figure 3 The symbol a represents the longitudinal center axis of the main beam, and the symbol b represents the rotation center axis of the support base. Since the upper flange 2, lower flange 3, and two semi-cylindrical structures are symmetrically arranged on the horizontal plane, the geometric center of the main beam lies on the longitudinal center axis of the main beam, and is located at the midpoint between the upper flange 2 and the lower flange 3. The rotation center axis is perpendicular to the longitudinal center axis of the main beam and is located above the geometric center of the main beam.

[0038] In the embodiment of the present application, the height of each semi-cylindrical structure is 400mm to 550mm, the radius is 150mm to 200mm, and the wall thickness is 8mm to 12mm, ensuring that the main beam has sufficient strength and rigidity. The distance between the inner connecting plates 12 of the two semi-cylindrical structures is 180mm to 220mm. This distance and the radius of the semi-circular semi-cylindrical structure provide sufficient space for the rotation of the support seat and the assembly of parts. The diameter of the upper flange 2 and the lower flange 3 is 620mm to 760mm. The diameter of the flange is designed to be larger than the diameter of the semi-cylinder to increase the stability of the connection and the mounting surface. The thickness is 8mm to 12mm to ensure that it can effectively support the heliostat truss. The diameter of each pin hole 10 is 30-40 mm and is used to install the pin shaft of the support seat to ensure its accuracy and stability during rotation. The geometric center of the main beam is located on the longitudinal center axis of the main beam body and at the midpoint between the upper flange 2 and the lower flange 3. For example, when the height of the semi-cylindrical structure is 500 mm, the height position of the geometric center of the main beam is 250 mm.

[0039] With the structure of this embodiment, the two semi-cylindrical structures are symmetrically arranged, and the rotation axis of the support seat is close to the geometric center of the main beam. This design helps to balance the forces during rotation and reduce the eccentric torque during rotation. This layout allows the load to be evenly distributed on both sides of the main beam structure when the support seat rotates around the axis, thereby improving the stability and operational efficiency of the system. The opening design of the main beam provides ample space, and the support seat can rotate smoothly and move toward the outside of the main beam, ensuring flexible installation and operation of the heliostat truss. The diameter of the upper flange and the lower flange is larger than that of the semi-cylindrical structure, and the stability of the installation is improved by increasing the connection area. The larger wall thickness ensures that the main beam can still maintain structural integrity under high loads, effectively resisting deformation, thereby stably supporting the heliostat truss.

[0040] Example 2

[0041] As the instruction manual Figure 4 This embodiment includes all the structures of Example 1, and the single-side open main beam further includes a main beam connector 5. The main beam connector 5 is a long strip structure installed horizontally on the upper flange 2, spanning the tops of the two semi-cylindrical structures. It is fixed to the upper flange 2 by bolts or welding to form a lateral support, effectively preventing the main beam from deforming under load, improving the overall rigidity and structural stability, ensuring the fixed spacing between the two semi-cylindrical structures, and avoiding spacing changes caused by external forces, thereby maintaining the geometric stability of the main beam.

[0042] In the embodiment of the present application, the width of the main beam connector 5 is about 50-80 mm, and the thickness is about 8-15 mm. High-strength steel or aluminum alloy is selected to take into account both strength and weight reduction.

[0043] A plurality of retaining grooves 30 are symmetrically distributed along the outer edges of the lower surface of the upper flange 2 and the upper surface of the lower flange 3 for positioning and limiting the installation of the heliostat truss. Each retaining groove 30 is provided with a heliostat truss mounting hole, which tightly mates with the locating pins or bolts of the mirror frame to provide a stable retaining effect.

[0044] In the embodiment of the present application, the retaining grooves 30 have a depth of 5-10 mm, a width of 20-30 mm, and a length of 50-150 mm, matching the mounting fixtures. The groove dimensions are designed based on the size of the mounting's locating pins or fixing bolts to ensure a tight fit. The design of the retaining grooves 30 simplifies the installation and adjustment process of the heliostat truss, improving assembly efficiency and accuracy. The symmetrical and even distribution of the retaining grooves 30 ensures comprehensive support and positioning, preventing the mounting from shifting or rotating during operation, significantly enhancing the system's wind resistance and operational stability.

[0045] Example 3

[0046] As the instruction manual Figure 5-6 Based on Example 1, this embodiment provides an application of a single-side open main beam for mounting a heliostat frame. The support seat 6 is located in the center of the main beam body 1 and is installed between the two semi-cylindrical structures. The support seat 6 is connected to the main beam body through a pin 7. Figure 5 At the section line position marked as AA, you can see that the pin passes through the top of the support base, allowing the support base to rotate stably and flexibly around the pin to achieve the pitch adjustment of the heliostat.

[0047] The housing of the electric push rod 8 is located between the two lugs 4 and is rotatably connected to the two lugs 4 by means of a hinge, ensuring that the push rod can rotate flexibly during the extension and retraction process, thereby adapting to the rotational movement of the support base. The push rod of the electric push rod 8 is connected to the bottom of the support base 6 by means of a hinge (at Figure 6 This connection method allows the push rod to work smoothly at different angles, avoiding excessive lateral stress that affects the stability of the system.

[0048] The core components of the electric push rod 8 include an electric motor, a reduction gear set, a lead screw mechanism, and a push rod. The electric motor drives the lead screw, and the relative motion between the lead screw and the nut converts rotational motion into linear motion, pushing or retracting the push rod. The electric motor is controlled by a control signal (such as a voltage or pulse signal) to rotate forward or reverse, thereby achieving the push rod's telescopic motion. This motion, through precise electronic control, enables precise angular adjustment of the heliostat support base 6. When the electronic control system issues a push rod extension command, the electric motor rotates forward, driving the lead screw through the gear reducer. The nut moves along the lead screw, pushing the push rod outward. At this point, the push rod pushes the main beam upward around the pin 7, increasing the pitch angle of the heliostat. To decrease the pitch angle, the electronic control system reverses, causing the electric motor to reverse, driving the lead screw in the opposite direction. The nut moves along the lead screw in the opposite direction, thereby retracting the push rod. As the push rod retracts, it pulls the main beam downward around the pin 7, decreasing the pitch angle of the heliostat.

[0049] The single-sided open main beam of this embodiment utilizes two spaced-apart semi-cylindrical structures, providing excellent structural strength and rigidity. This also provides ample room for rotation of the support base, satisfying the pitch adjustment requirements of the heliostat truss. The symmetrical arrangement of the semi-cylindrical structures ensures balanced force distribution, reduces eccentric torque, and improves rotational stability and angular adjustment accuracy. The main beam connectors enhance overall rigidity and prevent deformation, while the retaining groove design enables quick and precise installation of the heliostat truss.
