[0046] The embodiment provides a main beam mechanism for heliostat, which combines Figures 1 to 6 As shown in the drawings, the main beam mechanism for heliostat includes a main beam body 100, a support base 200, and a reinforcing member 300. The support base 200 includes a support body 210, the support body 210 is provided with an installation channel 211 matching the cross-sectional shape of the main beam body 100 along the axial direction of the main beam body 100, and the main beam body 100 is arranged in the installation channel 211; the reinforcing member 300 is arranged in the installation channel 211 and clamped between the support body 210 and the main beam body 100; or, along the axial direction of the main beam body 100, the reinforcing member 300 is arranged on one side of the support body 210; wherein, along the axial direction of the main beam body 100, the width of the reinforcing member 300 is greater than the width of the support body 210.
[0047] Specifically, as Figures 1 to 2As shown, generally, the main beam body 100 is designed in an elongated shape; the support base 200 comprises a support body 210, generally, the support body 210 is designed in a sheet shape, the support body 210 is provided with an installation channel 211 along the axial direction of the main beam body 100, the installation channel 211 is matched with the cross-sectional shape of the main beam body 100, and the support body 210 is sleeved on the main beam body 100 through the installation channel 211; the reinforcing member 300 is generally designed in a plate shape, the reinforcing member 300 is arranged in the installation channel 211 and clamped between the support body 210 and the main beam body 100; along the axial direction of the main beam body 100, the width of the reinforcing member 300 is greater than the width of the support body 210, and the reinforcing member 300 can disperse the stress from the support base 200 to different radial sections of the main beam body 100, thereby effectively avoiding the deformation of the main beam body 100 due to excessive stress at the position where the support body 210 is arranged.
[0048] In some embodiments, the reinforcing member 300 is welded to the main beam body 100 at the contour thereof, and the support body 210 is welded between the main beam body 100 at the contour of the installation channel 211.
[0049] Specifically, referring to the accompanying drawings Figure 2 As shown, generally, along the axial direction of the main beam body 100, the width of the reinforcing member 300 on both sides of the support body 210 is the same, and the contour of the reinforcing member 300 on both sides of the support body 210 is also the same; however, in other embodiments, along the axial direction of the main beam body 100, the width of the reinforcing member 300 on both sides of the support body 210 can be different; further, along the axial direction of the main beam body 100, the contour of the reinforcing member 300 on both sides of the support body 210 can also be different, here, the specific shape and installation position of the reinforcing member 300 are not limited too much, and can be designed according to the specific use condition.
[0050] In particular, in another embodiment, the width of the reinforcing member 300 is the same as the width of the support body 210 along the axial direction of the main beam body 100, but the reinforcing member 300 is positioned between the support body 210 and the main beam body 100 (i.e., along the axial direction of the main beam body 100, one side of the reinforcing member 300 protrudes from the mounting channel 211, and the other side does not protrude from the mounting channel 211, and the reinforcing member 300 and the main beam body 100 are connected by welding); or, the reinforcing member 300 is not positioned between the main beam body 100 and the support body 210, but is abutted against one side of the support body 210 along the axial direction of the main beam body 100, and the reinforcing member 300 is fixed on the support body 210 by welding. Of course, in this embodiment, the support body 210 can have the reinforcing member 300 welded on only one side, or can have the reinforcing member 300 welded on both sides, and the number of reinforcing members 300 on each side can not be only one, but can be designed according to the actual use. The reinforcing member 300 is welded at the contour thereof (generally, the contour refers to the contour of the surface of the reinforcing member 300 in contact with the main beam body 100), and the support body 210 is welded between the contour of the mounting channel 211 and the main beam body 100.
[0051] The foregoing structure and welding method make the welding range larger and not in the same cross section, reduce the transmission of torque and the concentrated stress when subjected to wind load, and improve the structural stability; at the same time, the above arrangement makes the welding longer and the welding away from the support seat 200, which can reduce the amount of thermal deformation of the support seat 200 during welding.
[0052] In other embodiments, the reinforcing member 300 and the main beam body 100 can not be connected by welding, but can be connected by screwing, riveting or gluing, etc. For example, the reinforcing member 300 is riveted to the main beam body 100 along the contour thereof by a plurality of rivets. Similarly, the support body 210 and the main beam body 100 can also not be connected by welding, but can be connected by screwing, riveting or gluing, etc. The connection method is not limited here, and can be designed according to the specific use. Preferably, the reinforcing member 300 and the main beam body 100 are connected by welding; the support body 210 and the main beam body 100 are connected by welding.
[0053] In some embodiments, the support body 210 is locally expanded at the mounting channel 211 to form a clamping groove 212, the reinforcing member 300 is arranged in the clamping groove 212, and two groove walls of the clamping groove 212 correspondingly abut two side walls of the reinforcing member 300 around the main beam body 100 in the axial direction to limit the lateral movement of the reinforcing member 300 along the circumference of the main beam body 100. In addition, the abutment of the groove walls of the clamping groove 212 and the side walls of the reinforcing member 300 can effectively increase the torque that can be transmitted between the support seat 200 and the main beam body 100. In addition, the arrangement of the clamping groove 212 provides a position guide for the installation of the reinforcing member 300. In the installation, the main beam body 100 is first arranged in the mounting channel 211, and then the reinforcing member 300 is arranged in the clamping groove 212, thereby improving the installation efficiency and position accuracy of the reinforcing member 300.
[0054] In use, the main beam body 100 is arranged on the main beam support b through the support seat 200, and the main beam mechanism for the heliostat has at least two support seats 200 arranged at intervals in the axial direction of the main beam body 100 to improve the support strength of the main beam body 100. In the embodiment, the two support seats 200 are arranged at intervals to facilitate the arrangement of a rotating shaft between the two support seats 200. The support body 210 is provided with a mounting hole 213 arranged at intervals with the mounting channel 211 in the axial direction of the main beam body 100. In general, the centers of all the mounting holes 213 on the support body 210 are located on a straight line, and the mounting hole 213 is used to connect the rotating shaft, wherein the rotating shaft is arranged in the main beam support b.
[0055] Regarding the matching relationship between the reinforcing member 300 and the support seat 200, in one embodiment of the present embodiment, the main beam mechanism for the heliostat has at least two reinforcing members 300 arranged one-to-one with at least two support seats 200. In the axial direction of the main beam body 100, the welding seams between the reinforcing member 300 and the main beam body 100 are symmetrical about the support seat 200. In another embodiment of the present embodiment, the main beam mechanism for the heliostat has one reinforcing member 300, and in the axial direction of the main beam body 100, the width of the reinforcing member 300 is greater than or equal to the distance between the adjacent two support seats 200. The reinforcing member 300 is located in the two mounting channels 211, and the two ends respectively extend out of the two corresponding mounting channels 211. Of course, in other embodiments, the reinforcing member 300 can be located in the two mounting channels 211, but the two ends can not extend out of the two corresponding mounting channels 211. As long as the width of the reinforcing member 300 is greater than or equal to the distance between the adjacent two support seats 200 in the axial direction of the main beam body 100, that is, one end of the reinforcing member 300 extends out of the corresponding mounting channel 211, and the other end is located in the corresponding mounting channel 211.
[0056] In some embodiments, the cross section of the main girder body 100 is circular, the reinforcing member 300 is an arc plate, and the radius is the same as the radius of the outer contour of the cross section of the main girder body 100. Generally, the main girder body 100 is a circular steel pipe, and the cross section of the main girder body 100 in the radial direction is circular, which is easy to process and low in cost; of course, in another embodiment, the cross section of the main girder body 100 in the radial direction can be rectangular, elliptical, polygonal, irregular, or the like, and the shape of the cross section of the main girder body 100 is not limited here and can be designed according to the actual situation. The arc plate and the main girder body 100 are matched in shape, which facilitates welding and makes the welding firm. To facilitate processing and installation, preferably, the arc of the arc plate is less than or equal to 180°; and in some special embodiments, the arc of the arc plate can also be greater than 180° and less than 360°, which can be designed according to the actual situation.
[0057] In some embodiments, the support body 210 is welded to the reinforcing member 300 at the contour of the mounting channel 211. Of course, in other embodiments, the reinforcing member 300 and the support body 210 can be integrally formed, thereby increasing the connection strength between the two. Exemplarily, the reinforcing member 300 and the support body 210 can be integrally formed by a casting process.
[0058] In some embodiments, the reinforcing member 300 is located on the side of the mounting channel 211 close to the mounting hole 213. This arrangement concentrates the stress on the side of the support body 210 close to the mounting hole 213, reduces the load bearing requirement of the side of the support body 210 away from the mounting hole 213, thereby helping to reduce the width of the support body 210 on the side away from the mounting hole 213, reduce the occupied space, and facilitate reasonable layout with other structures. Of course, in other embodiments, the reinforcing member 300 can also be arranged on the side of the support body 210 away from the mounting hole 213, which can be adjusted and designed according to the actual use.
[0059] Referring to FIG. 1, FIG. 2, and FIG. 3, the reinforcing member 300 is arranged on the side of the support body 210 close to the mounting hole 213, and the reinforcing member 300 is arranged on the side of the support body 210 away from the mounting hole 213. Figure 2 3 To increase the strength of the support seat 200, in some embodiments, the support seat 200 further comprises a reinforcing rib 220, the reinforcing rib 220 is in the form of a sheet and parallel to the axial direction of the main girder body 100, the reinforcing rib 220 is arranged on the support body 210 and connects the support body 210 and the reinforcing member 300. The reinforcing rib 220 has at least two, which are arranged on the two sides of the support body 210 along the axial direction of the main girder body 100. This arrangement effectively increases the load bearing capacity of the support seat 200 along the axial direction of the main girder body 100. In the axial direction of the main girder body 100, the two reinforcing ribs 220 on the same side of the support body 210 are arranged on the two sides of the axis of the main girder body 100.
[0060] In order to drive conveniently, the main beam mechanism for heliostat further comprises a push rod support e which is in transmission connection with the output end of the transmission mechanism d, the push rod support e is provided with a through hole, the main beam body 100 is arranged in the through hole and is welded with the push rod support e. In order to increase the connecting strength between the push rod support e and the main beam body 100, a reinforcing part 300 is arranged in the through hole and is clamped between the push rod support e and the main beam body 100.
[0061] In some embodiments, the push rod supports e and the support seats 200 are arranged at intervals, and one reinforcing part 300 can be shared between adjacent push rod supports e and support seats 200. For example, the reinforcing part 300 is arranged in the through hole and the mounting channel 211 and extends out of the through hole and the mounting channel 211 at two ends.
