Among them, tower CSP technology has developed rapidly in recent years due to its advantages in energy storage and peak shaving.

[0003] In tower solar thermal power generation, heliostats concentrate sunlight onto the receiver. Each field requires a large number of heliostats to reflect sufficient heat to the receiver, and each heliostat's mirror surface needs to be curved to concentrate and reflect sunlight onto the receiver on the tower. Therefore, the precision of the mirror frame assembly is crucial, and this precision depends on the drilling accuracy of the main beam and the riveting accuracy of the sub-beams. Drilling holes in the main beam is for installing the sub-beams, so the riveting accuracy of the heliostat sub-beams partly depends on the drilling accuracy.

[0044] Embodiment 1

[0045] Referring to Figures 1 to 4 , the present embodiment provides a hole position detection device, which comprises a support seat, a punching device 4 and a camera device 3.

[0046] The support seat comprises at least two first supports 1 arranged in parallel and spaced apart. The drilling device 4 is provided with a drill bit, and the drilling device 4 drills the at least two first supports 1 arranged in parallel and spaced apart on the support seat through the drill bit. The camera device 3 is arranged on the mounting seat 5, the lens of the camera device 3 is aligned with the drilling path of the drill bit in the drilling device 4, and the optical axis of the lens is perpendicular to the reference drilling path, the camera device 3 is configured to shoot the movement track of the drill bit in the drilling device 4 during drilling, and the picture shot by the camera device 3 is used for comparison with a preset picture to judge the drilling accuracy. The reference drilling path is a straight line where the axes of a plurality of through holes drilled by the drilling device 4 on the adjacent at least two first supports 1 under a preset condition (i.e. the condition that the axis of the drill bit is always perpendicular to the first support 1 in the support seat under normal circumstances).

[0047] The hole position detection device provided by the embodiment takes the drill bit in the drilling device 4 as a marker for hole position detection, and realizes rapid detection of the hole position on the first support 1 in the support seat in batch production. Specifically, the standard drilling of the support seat by the drilling device 4 (i.e. the drilling in which the axis of the drill bit is always perpendicular to the first support 1 in the support seat under normal circumstances) is taken as the comparison basis, and the picture shot by the camera device 3 during this process is the preset picture (which can be an actually shot picture or a picture obtained after computer processing). When drilling the support seat in batch, the picture shot by the camera device 3 during actual drilling is compared with the preset picture, the parameter difference is obtained by comparing the drill bit contour parameter in the preset picture (which is usually the included angle between the edge parallel to the axis of the drill bit in the preset picture and the adjacent edge parallel to the axis of the drill bit in the preset picture) with the drill bit contour parameter in the real-time shot picture by the camera device 3 (which is usually the included angle between the edge parallel to the axis of the drill bit in the real-time shot picture by the camera device 3 and the adjacent edge parallel to the axis of the drill bit in the real-time shot picture by the camera device 3), the parameter difference is compared with the preset threshold value, and the hole position accuracy is considered unqualified if the parameter difference exceeds the preset threshold value. The preset picture can be the following pictures:

[0048] During the standard drilling of the support seat by the drilling device 4, the picture (which can be an actually shot picture or a picture obtained after computer processing) between two adjacent first supports 1 (i.e. the two adjacent first supports 1 are the first support and the second support respectively) shot by the camera device 3 is usually the drill bit contour picture between the first support and the second support; or,

[0049] In a standard drilling process of the support seat by the drilling device 4, the picture between any two first supports 1 (i.e. any two first supports 1 are the third support and the fourth support respectively) taken by the camera device 3 (the picture can be the actually taken picture or the picture after computer processing) is usually the picture of the drill bit profile between the third support and the fourth support; or,

[0050] In a standard drilling process of the support seat by the drilling device 4, the picture between the first support 1 drilled first by the drilling device 4 and the first support 1 drilled last by the drilling device 4 taken by the camera device 3 (the picture can be the actually taken picture or the picture after computer processing) is usually the picture of the drill bit profile between the first support 1 drilled first by the drilling device 4 and the first support 1 drilled last by the drilling device 4.

[0051] Of course, the preset picture can also be other pictures (the picture can be the actually taken picture or the picture after computer processing) and is not limited to the above three pictures. The preset picture is not limited here and can be designed according to the actual situation.

[0052] The preset threshold value compared with the parameter difference can also be designed according to the actual situation. For example, the axis of the through hole formed by the drilling device 4 on the first supports 1 in the support seat is usually perpendicular to the first support 1. Therefore, in the picture taken by the camera device 3, the shape formed between two adjacent first supports 1 by the drill bit should be a rectangle. When the axis of the through hole is inclined (i.e. the drill bit is inclined), the shape formed between two adjacent first supports 1 by the drill bit becomes a parallelogram (the parallelogram here does not include a rectangle). The angle between two adjacent sides of the parallelogram can be used to obtain the deviation angle of the axis of the through hole. For another example, in another specific embodiment, in a standard drilling process of the support seat by the drilling device 4, the picture taken by the camera device 3 is the preset picture (the picture can be the actually taken picture or the picture after computer processing). In the preset picture, the girder 11 is a rectangle, the drill bit of the drilling device 4 is also a rectangle, and the side of the profile picture of the girder 11 close to the drill bit is parallel to the side of the profile picture of the drill bit close to the girder 11. When the axis of the through hole is inclined (i.e. the drill bit is inclined), the side of the profile picture of the girder 11 close to the drill bit is not parallel to the side of the profile picture of the drill bit close to the girder 11 in the picture taken by the camera device 3. The angle between the extension line of the side of the profile picture of the drill bit close to the girder 11 and the side of the profile picture of the girder 11 close to the drill bit can be used to obtain the deviation angle of the axis of the through hole.

[0053] The structure of the embodiment will be described.

[0054] In general, the support seat generally includes two first supports 1 arranged in parallel and spaced apart, and the punching device 4 punches one first support 1 in the support seat at a time, that is, the punching device 4 completes the punching of two first supports 1 in the support seat in one punching process. The camera device 3 is preferably arranged at a position where the space between the two adjacent first supports 1 in the support seat is a detection space, and the optical axis of the lens is located in a preset detection space, and the detection space in which the optical axis of the lens is located is defined as a first detection space, and more preferably, the distance between the optical axis of the lens and the two first supports in the first detection space is equal. Of course, in other embodiments, there can be three or more first supports 1 on the support seat, and more accurate detection of the hole positions on which two adjacent first supports 1 is preferred, and the optical axis of the lens can be arranged in the detection space formed by the two adjacent first supports 1.

[0055] Further, in other embodiments, the support seat can include two or more first supports 1 arranged in parallel and spaced apart, and the punching device 4 punches one first support 1 in the support seat at a time, that is, the punching device 4 completes the punching of all the first supports 1 in the support seat in one punching process. The camera device 3 is arranged above the entire punching path and photographs the entire punching path. The photographed picture (here, the photographed picture does not only refer to the drill bit picture between the two adjacent first supports 1 photographed by the camera device 3, but also can be the drill bit picture between any two first supports 1 photographed by the camera device 3, or the drill bit picture between the first support 1 first punched by the punching device 4 and the first support 1 last punched by the punching device 4) is compared with a preset picture, the parameter difference is obtained by comparing the drill bit contour parameters in the preset picture with the drill bit contour parameters in the real-time photographed picture by the camera device 3, and the parameter difference is compared with a preset threshold value, and if the parameter difference exceeds the preset threshold value, it is considered that the hole position accuracy is unqualified. In this embodiment, there are various comparison methods, such as when the photographed picture is the drill bit picture between any two first supports 1 photographed by the camera device 3 in one punching process of the punching device 4, or the drill bit picture between the first support 1 first punched by the punching device 4 and the first support 1 last punched by the punching device 4 in one punching process of the punching device 4, in such photographed drill bit pictures, the photographed drill bit picture can be divided into the same number of segments by the first supports 1;

[0056] In this case, each segment can be extracted and compared with the preset picture (at this time, the preset picture is the drill bit picture between two adjacent first supports 1 photographed by the camera device 3 during a standard punching process of the support seat by the punching device 4), or the drill bit picture photographed by the camera device 3 during the entire punching process can be compared with the preset picture (at this time, the preset picture is the drill bit picture between the first support 1 first punched by the punching device 4 and the first support 1 last punched by the punching device 4 photographed by the camera device 3 during a standard punching process of the support seat by the punching device 4), and the specific adjustment can be made according to the actual situation.

[0057] Of course, in other embodiments, there can also be a case where the photographed drill bit picture is divided into different segments by a plurality of first supports 1, such as when the photographed picture is the drill bit picture between any two first supports 1 photographed by the camera device 3 during a punching process of the punching device 4, or the drill bit picture between the first support 1 first punched by the punching device 4 and the first support 1 last punched by the punching device 4 photographed by the camera device 3 during a punching process of the punching device 4, and the preset picture and the comparison method can be adjusted according to the actual situation.

[0058] In another embodiment, the camera device 3 can be mounted on the mounting seat 5 through an adjustment structure for adjusting the relative position of the camera device 3 on the mounting seat 5, so as to accurately adjust the position of the camera device 3.

[0059] Specifically, the adjustment structure includes an offset component, and the offset component includes an offset fixed base 6, a lead screw 7, and a moving member 8.

Of course, in other embodiments, the offset sliding groove can not be arranged in parallel to the direction of the reference punching path, and the offset sliding groove can be arranged as long as it can meet the requirement that the moving member 8 moves in parallel to the direction of the reference punching path. The two ends of the lead screw 7 are rotatably connected with the offset fixed base 6, and the axis direction of the lead screw 7 is parallel to the direction of the reference punching path, and the lead screw 7 penetrates the moving member 8 and is threadedly connected therewith. The camera device is arranged on the moving member 8. In this way, the left and right positions (i.e., the positions in parallel to the direction of the reference punching path) of the camera device 3 can be adjusted by rotating the lead screw 7.

[0060] Further, the camera device 3 and the moving member 8 are further provided with a lifting assembly, which comprises a lifting fixing member, the device fixing member 9 and a lifting locking member 10. The camera device 3 is connected to the device fixing member 9, and the device fixing member 9 is slidingly connected to the lifting fixing member along the optical axis direction of the lens. The lifting locking member 10 is connected to the lifting fixing member and the device fixing member 9 respectively, and is used for locking the relative position of the lifting fixing member and the device fixing member 9. The lifting fixing member can be the moving member 8, or can be detachably arranged on the moving member 8, which is not limited here. In this embodiment, the lifting fixing member is the moving member 8.

[0061] Specifically, referring to Figure 2 , the lifting fixing member is provided with a lifting guide slot arranged along the optical axis direction of the lens, and the device fixing member 9 is slidingly connected in the lifting guide slot. The side wall of the lifting guide slot is provided with a locking groove, and the device fixing member 9 is provided with a locking portion protruding into the locking groove, which can move along the optical axis direction of the lens in the locking groove. The two side walls of the locking groove are respectively provided with a locking hole corresponding to the lifting locking member 10, and the device fixing member 9 is provided with a plurality of adjusting holes arranged along the optical axis direction of the lens.
