[0040] Based on the above heliostat mirror frame, the embodiment further discloses a heliostat, which comprises a reflector 1, a stand 3, an electric push rod 4, a rotary reducer 5, a heliostat mirror frame 2 as described above, and a connecting assembly 6. Figure 5 As shown, the connecting seat 6.3 of the mirror frame and the connecting assembly 6 is connected by a fixing bolt, and the hole position 6.1.8 of the base is connected with the rotary reducer by a bolt. The rotary reducer drives the connecting assembly 6 to rotate horizontally around the stand to realize the azimuth angle adjustment of the heliostat. The trunnion of the mirror frame and the electric push rod is connected through a bracket, and the end shaft hole of the electric push rod is connected with the hinged hole position 6.1.1 through a fixing bolt. The electric push rod is extended and retracted to drive the reflector to rotate vertically around the rotating shaft of the support flange assembly to realize the pitch angle adjustment of the heliostat.

[0041] The reflector 1 (composed of the reflector 1 and the mirror frame 2) of the heliostat is connected with the rotary reducer and the electric push rod through the connecting assembly 6. The connecting seat 6.3 of the mirror frame and the connecting assembly 6 is connected by a fixing bolt, and the hole position 6.1.8 of the base is connected with the rotary reducer by a bolt. The rotary reducer drives the connecting assembly 6 to rotate horizontally around the stand to realize the azimuth angle adjustment of the heliostat. The trunnion of the mirror frame and the electric push rod is connected through a bracket, and the end shaft hole of the electric push rod is connected with the hinged hole position 6.1.1 through a fixing bolt. The electric push rod is extended and retracted to drive the reflector to rotate vertically around the rotating shaft of the support flange assembly to realize the pitch angle adjustment of the heliostat.

[0042] The heliostat is composed of 12 pieces of reflectors 1, 4 pieces of which are symmetrically arranged along the main pipe axis, and 3 pieces of which are arranged perpendicular to the main pipe axis. The mirror piece 1.1 of the reflector is connected with the bonding tray 1.3 through an adhesive 1.2 (as shown in Figure 10 The bonding tray 1.3 is fixed with the mirror frame through bolt connection to realize the connection of the mirror piece and the mirror frame; the bonding tray 1.3 is provided with adhesive thickness limiting protrusions 1.3.1 (3 in this embodiment, not limited), as shown in Figure 11As shown, the convex point 1.3.1 is higher than the bonding surface 0.5mm, and the bonding process is usually completed automatically by a robot, and the thickness of the adhesive is controlled at about 1mm, and the role of the convex point can ensure that the bonding strength is ensured when the precision control deviation of the robot is large, and the bonding strength is ensured.

[0043] As shown in the figure, the connecting assembly comprises an L-shaped support flange 6.1, a rotating shaft 6.2, a connecting seat 6.3, and a sliding bearing 6.4. Figures 7-9 As shown, the connecting assembly comprises an L-shaped support flange 6.1, a rotating shaft 6.2, a connecting seat 6.3, and a sliding bearing 6.4.

[0044] The transition connection between the mounting hole and the base is provided as an arc surface structure; the middle position of the mounting hole is a rotating shaft mounting hole 6.1.3; the rotating shaft is mounted at the rotating shaft mounting hole, and a sliding bearing 6.4 is provided between the rotating shaft and the rotating shaft mounting hole, and the middle part of the rotating shaft corresponding to the sliding bearing is provided with an O-ring groove; the two ends of the rotating shaft are provided with an oil seal 6.5 and a connecting seat 6.3. One end of the connecting seat is connected with the mirror frame rotating shaft support seat, and the other end is matched with the L-shaped support flange.

[0045] The base 6.1.1 is a cylindrical stepped structure, which can withstand torque or load in all directions and has high rigidity. A hinge hole position 6.1.2 matched with the shaft hole of the push rod end is arranged at the base, and the center axis 6.1.6 of the hole is parallel to the rotating shaft axis 6.1.4; the bottom flange 6.1.9 of the base is connected with the rotary reducer, and corresponds to the azimuth axis 6.1.5 of the heliostat.

[0046] The arc surface structure reserves an electric push rod cable routing hole position (a side elliptical hole 6.1.8) and (a front rounded rectangular 6.1.7); with the extension and contraction of the electric push rod, the power supply and communication cables need to be reserved for a certain length, in order to avoid the cables from drooping and interfering with the movement of other parts, the cables are wound around a torsion tube, and pass through the front rounded rectangular 6.1.7 and the hole position side elliptical hole 6.1.8 to be connected with the electric control box.

[0047] The thickness of each structure of the L-shaped support flange is uniform and basically consistent, and the connection is rounded and transitioned, which can avoid casting defects caused by internal stress concentration and has a high yield.

[0048] According to the different distances f from the center point of the reflecting surface to the heat absorber, the curvature radius R of the surface of the reflector needs to be adjusted, that is, the elevation of the support point of the reflecting mirror needs to be adjusted, and the specific implementation manner is as follows:

[0049] The connecting hole groups 1-8 on each claw assembly of the twisted tube are machined to create an arc-shaped height difference between the relative positions of the connecting hole groups along the axis of the circular tube, thereby achieving X-axis curvature adjustment of the reflector. The specific height difference value needs to be based on the spacing between the claw assemblies and the curvature requirements of the heliostat surface, and the deformation value of the reflector on the twisted tube assembly under the action of gravity is compensated to obtain the overall height difference value.

[0050] Along the length of the support beam, adjusting shims of varying thicknesses are installed at the bolt holes of the reflector mounting tray. The relative positions of the top surfaces of these shims create an arc-shaped height difference along the length of the support beam, thus adjusting the Y-axis curvature of the reflector. The specific height difference value needs to be determined based on the spacing between the reflector's mounting points and the curvature requirements of the heliostat surface, while also compensating for the deformation of the reflector on the support beam assembly under gravity. The shim thickness value is then calculated by combining these factors.

[0051] When the X and Y radii of curvature R satisfy R=2f, the astigmatism of the light spot reflected to the receiver is small.

[0052] Typically, depending on the scale of the heliostat field and its distance from the receiver, several heliostats with different curvatures are used in engineering applications. Heliostat assembly workshops are usually set up on-site. Construction of the field typically proceeds gradually from the inside out or from the outside in, with the assembly curvature of the heliostats adjusted according to the construction progress. The connecting holes on the torsion tube assembly are machined in the assembly workshop based on curvature requirements. Adjusting shims are provided in several different thicknesses, which are combined and installed according to thickness requirements. Therefore, by adjusting the position of the machined hole groups and the thickness of the adjusting shims, the surface curvature of the heliostat reflector can be easily adjusted without affecting the supply of components or the assembly process.

[0053] Considering the operating environment of the heliostat, the entire torsion tube assembly is hot-dip galvanized for protection. The support beams, diagonal braces, and purlins are made of zinc-aluminum-magnesium sheet metal, and the connecting pins and fasteners are made of stainless steel or Dacromet surface-treated materials, giving the entire frame good corrosion resistance.

[0054] To ensure that the center of mass of the reflector (composed of reflector 1 and mirror frame 2) passes through the center of the pivot support hole, the middle connecting hole of the support beam assembly is offset relative to the center, so that the length L5 of the support beam near the pivot support is greater than the length L6 of the support beam at the other end; the circular holes at both ends of the support beam assembly for connecting with the diagonal brace assembly are basically the same distance from the two ends of the support beam, and the length of the diagonal brace assembly near the pivot support is greater than the length of the diagonal brace assembly near the push rod support.

[0055] like Figure 6 As shown, in order to precisely control the pitch angle of the heliostat by controlling the extension and retraction of the electric actuator, the structural dimensions of each component should meet the following relationship:

[0056] The line L1 (fixed length) connecting the center of the shaft support seat hole (passing through the overall center of gravity of the reflector) and the center of the push rod support seat hole, the line L2 (fixed length) connecting the center of the shaft hole of the support flange and the center of the push rod hinge hole, and the line L3 (changing with the extension and retraction of the electric push rod) connecting the center of the push rod trunnion and the end shaft hole form a reflector pitching movement relationship, the angle between L1 and L2 is A, according to the cosine theorem: L3 2 =L1 2 +L2 2 -2*L1*L2*cosA, the change amount of L3 and the adjustment amount of the pitching angle are related. The length L4 of the push rod trunnion to the end needs to meet the kinematic check to avoid interference with the reflector lens within the pitching angle adjustment range (0-90°).

[0057] After the whole twist pipe assembly is welded, process holes 1-6 are processed, which are perpendicular to the positioning reference surface P and symmetrically pass through the center section of the main pipe, specifically, two holes are arranged near the middle pair of clamping jaw assemblies, which are used as lifting process holes 3-4 of the twist pipe assembly, a hook is hung in the two holes, and the twist pipe assembly is lifted and carried. Two holes (process holes 1-2 and process holes 5-6) are arranged near the clamping jaw assemblies at both ends, which are used as process holes for assembling the support beam assembly, the diagonal brace assembly, the reflector and the twist pipe assembly. After a matched round bar (preferably made of steel) is clamped after passing through the round hole, the twist pipe can be fixed, the other function is that when the mirror frame and the reflector are assembled to form a whole reflector, the round bar is hung by a crane to realize the transfer and installation of the reflector.

[0058] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements should also be considered to fall within the protection scope of the present application.
