Description

Technical Field

[0001] The invention belongs to the technical field of heliostats, and in particular relates to a main beam structure of a heliostat. Background Art

[0002] As a clean and renewable energy source, solar energy is increasingly being used, especially solar thermal power generation technology, which is an emerging solar energy utilization technology after photovoltaic power generation technology. Among them, tower solar thermal power generation technology has developed rapidly in recent years due to its advantages in energy storage and peak regulation.

[0003] The function of the heliostat in the tower solar thermal power generation is to focus sunlight onto the absorber. Each mirror field requires a large number of heliostats to reflect enough heat to the absorber. The main beam is the main load-bearing component in the mechanical structure of the heliostat, and its strength is directly related to the accuracy and stability of the heliostat. At the same time, the heliostat uses a large amount of steel, and the cost issue needs to be considered. Therefore, the mechanical structure of the heliostat must be designed with both strength and low cost.

[0004] Moreover, after the heliostat is installed, the pressure of the entire mirror body acts on the main beam support weldment, and the rotational driving force acts on the support beam support weldment. The main beam support weldment and the support beam support weldment are arranged on the main beam of the heliostat, so the pressure of the heliostat acts on the main beam of the heliostat through the main beam support weldment and the support beam support weldment. Therefore, as the heliostat mirror surface continues to increase, the main beam of the heliostat needs to have better rigidity to ensure that the main beam of the heliostat remains stable and does not deform during processing, transportation, and use.

[0011] In a heliostat main beam structure provided in a certain embodiment, the side reinforcement member is a side reinforcement plate, and the side reinforcement plate is perpendicular to the connection member of the connection support attached thereto.

[0012] In a heliostat main beam structure provided in a certain embodiment, along the axial direction of the main beam, the length of the limiting section is greater than the length of the penetration section.

Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0021] In order to simplify the drawings, only the parts related to the present invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0022] See also Figures 1 to 3 The present embodiment provides a heliostat main beam structure, including a main beam 1, an intermediate reinforcement 4 and a side reinforcement 5. At least two connection supports arranged side by side and spaced apart are installed on the main beam 1. The intermediate reinforcement 4 penetrates into the main beam 1 from one side of the main beam 1 and then passes out from the other side of the main beam 1, and the intermediate reinforcement 4 is installed on the main beam 1. The side reinforcement 5 includes a limiting section 51 and a penetration section 52; the limiting section 51 is installed between the two connection supports, and the penetration section 52 penetrates into the main beam 1 from one side of the main beam 1 and then abuts against the intermediate reinforcement 4.

[0023] Among them, each connecting support is respectively provided with a connecting shaft hole, and the limiting section 51 is configured to limit the positional relationship between the two connecting supports (the two connecting supports here refer to the two connecting supports on which the above-mentioned limiting section 51 is installed) so that the center lines of the connecting shaft holes of the two connecting supports are located on the same straight line.

[0024] The heliostat main beam structure provided in this embodiment significantly improves the strength of the heliostat main beam structure while adding a small amount of material, and improves the stability of the heliostat precision by installing an intermediate reinforcement member 4 on the main beam 1 and arranging side reinforcement members 5 installed in two connecting supports to penetrate into the main beam 1 and abut against the intermediate reinforcement member 4 in the main beam 1.

[0025] It should be noted that, in the following text, unless otherwise specified, the connection supports described in connection with the side reinforcement 5 refer to the two connection supports in which the above-mentioned limiting sections 51 are installed.

[0026] Generally, the connection support includes a connection piece, the connection shaft hole is provided on the connection piece, and the connection piece is a sheet structure. The limiting section 51 includes a first end face and a second end face, and the first end face and the second end face are preferably two end faces arranged opposite to each other on the limiting section 51. The limiting section 51 is arranged between the two connection supports, and the first end face on the limiting section 51 is attached to the connection piece of any one connection support, and the second end face on the limiting section 51 is attached to the connection piece of the other connection support. Among them, the first end face and the second end face are parallel to each other to ensure that the connection pieces of the two connection supports are parallel to each other. In an ideal state, the connecting pieces of the two connecting supports installed on the main beam 1 are parallel to each other, and the connecting shaft holes on the connecting pieces of the other two connecting supports are located on the same straight line; however, when the connecting support is welded to the main beam 1 (welding here may refer to the connecting support being directly welded to the main beam 1, or may refer to the connecting support being connected to other components, and the other components being welded to the main beam 1), in the actual operation process, the main beam 1 is easily deformed due to welding, resulting in a change in the relative position between the two connecting supports welded on the main beam 1, so that the connecting pieces of the two connecting supports are no longer parallel, and the connecting shaft holes on the connecting pieces of the two connecting supports are no longer located on the same straight line, thereby affecting the subsequent installation of other components. In this embodiment, by providing a limiting section 51 (specifically, the first end face and the second end face on the limiting section 51), even if the main beam 1 is deformed due to welding, the connecting pieces of the two connecting supports can be ensured to be parallel to each other, thereby ensuring that the connecting shaft holes on the connecting pieces of the two connecting supports are located on the same straight line. The shape of the side reinforcement is not restricted here and can be designed according to actual conditions, as long as the positions of the two connecting supports can be limited by the limiting section 51 so that the center lines of the connecting shaft holes on the two connecting supports are located on the same straight line.

[0027] It should be specially noted that, generally, the limiting section 51 is arranged between the connecting parts of the two connecting supports, and the parallelism of the two sheet-like connecting parts is limited by the parallelism of the first end face and the second end face, so that the center lines of the connecting shaft holes on the two connecting supports are located on the same straight line; but in other embodiments of the present scheme, in addition to the connecting parts, there may be other parts in the connecting support (for the convenience of description, the other parts are referred to as part No. 1), the connecting parts are arranged on part No. 1, and the limiting section 51 is arranged between the part No. 1 of the two connecting supports, and the part No. 1 of the two connecting supports may not be arranged in parallel, then the first end face and the second end face of the limiting section 51 are also not arranged in parallel at this time, and the relationship between the first end face and the second end face only needs to satisfy the limitation of the part No. 1 of the two connecting supports, and then constrain the relationship between the connecting parts of the two connecting supports (that is, the connecting parts of the two connecting supports are parallel to each other), that is to say, the limiting section 51 can directly limit the relationship between the connecting parts of the two connecting supports, and can also indirectly limit the relationship between the connecting parts of the two connecting supports.

[0028] Specifically, the limiting section 51 of the side reinforcement member 5 and the connecting support may be welded, or the limiting section 51 of the side reinforcement member 5 and the connecting support may be integrally formed.

[0029] The middle reinforcement 4 is provided with a slot corresponding to the penetration section 52 of the side reinforcement 5, and the slot is located in the main beam 1, and the penetration section 52 penetrates the main beam 1 from one side of the main beam 1 and is inserted and connected to the slot. The middle reinforcement 4 is a rod, a pipe or a plate.

[0030] The main beam 1 is provided with two through holes for the intermediate reinforcement 4 to pass through. The intermediate reinforcement 4 passes through one of the through holes into the main beam 1 and passes through the other through hole out of the main beam 1. Preferably, the intermediate reinforcement 4 and the main beam 1 are fully welded at the through holes.

[0031] Preferably, the side reinforcement member 5 is a side reinforcement plate, and the side reinforcement plate is perpendicular to the connecting member of the connecting support affixed thereto. It should be particularly noted that when the side reinforcement member 5 is determined to be a side reinforcement plate, in order to achieve the limiting effect of the limiting section 51, then among several connecting supports, the side reinforcement plate needs to be arranged between two adjacent connecting supports, and the side reinforcement plate is perpendicular to the connecting member of the connecting support affixed thereto.

[0032] Preferably, along the axial direction of the main beam 1, the length of the limiting section 51 is greater than the length of the penetration section 52, that is, Figure 3 As shown, the shape of the side reinforcement plate is similar to a T. Compared with the rectangular side reinforcement plate, such a design can improve the strength of the main beam at this position (i.e., the position where the side reinforcement plate is installed) while reducing the amount of material used, and minimize the size of the opening on the main beam for inserting the through-section 52.

[0033] Furthermore, the heliostat main beam structure further includes at least one fitting member 6, on which the connecting support is mounted, that is, the connecting support is connected to the fitting member 6, and the fitting member 6 is welded to the main beam 1. Among the plurality of connecting supports, at least two connecting supports are arranged in a one-to-one correspondence with at least two fitting members 6 (e.g. Figure 3 The push rod support 3 and the other corresponding fittings 6 are arranged in a manner), and / or, among the plurality of connecting supports, at least two connecting supports are arranged on the same fitting 6 (such as Figure 3 The middle main beam support 2 and the other corresponding fittings 6 are arranged). The fittings 6 are fitted to the outer wall of the main beam 1 and are welded to the main beam 1.

[0034] Specifically in this embodiment, Figure 3 As shown, there are four connecting supports of the main beam structure of the heliostat, of which two connecting supports are main beam supports 2 and two connecting supports are push rod supports 3. The two main beam supports 2 are respectively mounted on two fittings 6, and a side reinforcement plate is mounted between the two main beam supports 2. The penetration section 52 of the side reinforcement plate mounted between the two main beam supports 2 penetrates the main beam 1 and abuts against the middle reinforcement 4. The two push rod supports 3 are mounted on the same fitting 6, and another side reinforcement plate is mounted between the two push rod supports 3. The penetration section 52 of the side reinforcement plate mounted between the two push rod supports 3 penetrates the main beam 1 through the fitting 6 and abuts against the same middle reinforcement 4. Of course, in other embodiments, the connecting support may also include a sub-beam support, and a side reinforcement plate may also be arranged between the two sub-beam supports and a corresponding middle reinforcement 4 may be provided in cooperation, so as to ensure the parallelism of the connecting parts of the two sub-beam supports after welding while strengthening the structural strength.

[0035] The connecting shaft hole on the main beam support 2 is a first connecting shaft hole, and the center lines of all the first connecting shaft holes are located on the first axis; the connecting shaft hole on the push rod support 3 is a second connecting shaft hole, and the center lines of all the second connecting shaft holes are located on the second axis; the first axis is parallel to the second axis. Among them, the connecting shaft hole on the main beam support 2 is used to install the rotating shaft, the main beam 1 is installed on the supporting structure through the rotating shaft, and the connecting shaft hole on the push rod support 3 is used to install the push rod.

[0036] In the heliostat main beam structure provided in this embodiment, the main beam support 2 and its corresponding side reinforcement plates, the push rod support 3 and its corresponding side reinforcement plates and the middle reinforcement member 4 are assembled by tooling positioning before welding (i.e., the side reinforcement plates corresponding to the main beam support 2 and the main beam support 2 are first positioned and welded, the side reinforcement plates corresponding to the push rod support 3 and the push rod support 3 are first positioned and welded, and the middle reinforcement member 4 is first installed in the main beam 1). After assembly, the side reinforcement plates corresponding to the main beam support 2, the side reinforcement plates corresponding to the push rod support 3 and the middle reinforcement member 4 are respectively fully welded with the main beam 1 at the joints to form a stable support structure. The welding of the limiting section 51 of the side reinforcement plate corresponding to the main beam support 2 and the connecting piece of the main beam support 2 can ensure the spacing size and parallelism accuracy between the connecting pieces of the two main beam supports 2. The welding of the limiting section 51 of the side reinforcing plate corresponding to the push rod support 3 and the connecting piece of the push rod support 3 can ensure the spacing size and parallelism accuracy between the connecting pieces of the two push rod supports 3 .

[0037] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments.
