[0003] The function of the heliostat in the tower solar thermal power generation is to focus the sunlight on the absorber. Each mirror field requires a large number of heliostats to reflect enough heat to the absorber. The mirror surface of each set of heliostats needs to form a certain curved surface to focus the sunlight and reflect it to the absorber on the absorber tower. Therefore, the accuracy of the mirror frame assembly is particularly important, and the accuracy of the mirror frame assembly depends on the accuracy of the main beam drilling and the riveting of the secondary beam.

Specifically, the drilling device performs a standard drilling on the first support as a comparison basis, and the picture taken by the camera device during this process is the preset picture (the picture can be a picture actually taken, or a picture obtained after computer processing). Then, when the support seats are drilled in batches, the picture taken by the camera device during the actual drilling process is compared with the preset picture, and the parameter difference is obtained by comparing the drill bit profile parameters in the preset picture with the drill bit profile parameters in the real-time picture taken by the camera device 3, and the parameter difference is compared with the preset threshold value.

In this article, "one" not only means "only one", but also means "more than one".

[0044] Example 1

[0045] See also Figures 1 to 4 This embodiment provides a hole position detection device, including a support seat, a punching device 4 and a camera device 3.

[0046] The support seat includes at least two first supports 1 that are parallel to each other and spaced apart. A drill bit is installed in the punching device 4, and the punching device 4 uses the drill bit to punch holes in the at least two first supports 1 that are parallel to each other and spaced apart on the support seat in sequence. The camera device 3 is arranged on the mounting seat 5, and the lens of the camera device 3 is aimed at the punching path of the drill bit in the punching device 4, and the optical axis of the lens is perpendicular to the reference punching path. The camera device 3 is configured to shoot the movement trajectory of the drill bit of the punching device 4 during the punching process, and the picture shot by the camera device 3 is used for comparison with the preset picture to determine the punching accuracy. Among them, the reference punching path is a straight line where the axes of several through holes formed by the punching device 4 on at least two adjacent first supports 1 under a preset condition (that is, the preset condition is usually that the axis of the drill bit is always perpendicular to the first support 1 in the support seat) are located.

[0047] The hole position detection device provided in this embodiment uses the drill bit in the punching 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 mass production. Specifically, the punching device 4 performs a standard punching on the support seat (that is, under normal circumstances, the standard punching is that during the punching process, the axis of the drill bit is always perpendicular to the first support 1 in the support seat to punch the hole) as a comparison basis, and the picture taken by the camera device 3 during this process is the preset picture (the picture can be a picture actually taken, or a picture obtained after computer processing). When drilling holes in batches on the support seat, the picture taken by the camera device 3 during the actual drilling process is compared with the preset picture, and the parameter difference is obtained by comparing the drill bit profile parameter of the preset picture (the parameter is usually the angle between the side parallel to the drill bit axis in the preset picture and the adjacent side parallel to the drill bit axis in the preset picture) with the drill bit profile parameter in the real-time picture taken by the camera device 3 (the parameter is usually the angle between the side parallel to the drill bit axis in the real-time picture taken by the camera device 3 and the adjacent side parallel to the drill bit axis in the real-time picture taken by the camera device 3). The parameter difference is compared with the preset threshold value, and the hole position accuracy is considered unqualified if it exceeds the preset threshold value. Among them, the preset picture can be the following pictures:

[0048] During a standard drilling process of the punching device 4 on the support seat, the camera device 3 takes a picture between two adjacent first supports 1 (i.e., the two adjacent first supports 1 are support No. 1 and support No. 2, respectively) (the picture may be a picture actually taken or a picture obtained after computer processing), which is usually a picture of the drill bit outline between support No. 1 and support No. 2; or,

[0049] During a standard drilling process of the punching device 4 on the support seat, the camera device 3 takes a picture between any two first supports 1 (i.e., any two first supports 1 are support No. 3 and support No. 4) (the picture may be a picture actually taken or a picture obtained after computer processing), which is usually a picture of the drill bit outline between support No. 3 and support No. 4; or,

[0050] During a standard drilling process of the support seat by the punching device 4, the camera device 3 captures a picture between the first support 1 punched first by the punching device 4 and the first support 1 punched last by the punching device 4 (the picture may be a picture actually captured or a picture obtained after computer processing). Generally speaking, the picture is a picture of the drill bit outline between the first support 1 punched first by the punching device 4 and the first support 1 punched last by the punching device 4.

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

[0052] As for the preset threshold value for comparison with the parameter difference, it can also be specifically designed according to the actual situation. For example, the through holes formed by the punching device 4 on the first supports 1 in the support seat usually have an axis perpendicular to the first supports 1. Therefore, in the picture taken by the camera device 3, when the drill bit passes through two adjacent first supports 1, the shape formed between the two first supports 1 should be a rectangle. When the axis of the through hole is tilted (that is, the drill bit for drilling is tilted), the shape formed by the drill bit between the two first supports 1 will become a parallelogram (the parallelogram here does not include a rectangle). The offset angle of the axis of the through hole can be obtained by the angle between two adjacent sides of the parallelogram. For example, in another specific embodiment, during a standard drilling process of the support seat by the punching device 4, the picture taken by the camera device 3 is a preset picture (the picture can be a picture actually taken or a picture obtained after computer processing). In the preset picture, the main beam 11 is a rectangle, the drill bit of the punching device 4 is also a rectangle, and the side of the outline picture of the main beam 11 close to the drill bit is parallel to the side of the outline picture of the drill bit close to the main beam 11; when the axis of the through hole is tilted (that is, the drilling drill bit is tilted), the side of the outline picture of the main beam 11 close to the drill bit in the picture taken by the camera device 3 will not be parallel to the side of the outline picture of the drill bit close to the main beam 11, and the offset angle of the axis of the through hole can be obtained by the angle between the extension line of the side of the outline picture of the drill bit close to the main beam 11 and the side of the outline picture of the main beam 11 close to the drill bit.

[0053] The structure of this embodiment is now described.

[0054] Normally, the support seat generally includes two first supports 1 that are parallel to each other and spaced apart. The punching device 4 punches holes in one first support 1 in the support seat each time when punching holes. That is, the punching device 4 completes the punching of two first supports 1 in one support seat in one punching process. The setting position of the camera device 3 is preferably: the space between two adjacent first supports 1 in the support seat is the detection space, the optical axis of the lens is located in the preset detection space, and the detection space where the optical axis of the lens is located is defined as the first detection space. The more preferred situation is that the distance from the optical axis of the lens to the two first supports in the first detection space is equal. Of course, in other embodiments, it is not excluded that there are three or more first supports 1 on the support seat. At this time, it is more inclined to perform more accurate detection on the hole positions on which two adjacent first supports 1, and the optical axis of the lens can be set in the detection space formed by the two adjacent first supports 1.

[0055] Further, in other embodiments, the support seat may include more than two first supports 1 that are parallel to each other and spaced apart, and the punching device 4 punches holes in the first supports 1 in one support seat at a time during the punching process, that is, the punching device 4 completes the punching of all the first supports 1 in one support seat in one punching process. The camera device 3 is arranged above the entire punching path, and shoots the entire punching path. The shot picture (the shot picture here does not only refer to the drill picture between two adjacent first supports 1 shot by the camera device 3, and the picture can also be the drill picture between any two first supports 1 shot by the camera device 3, or the drill picture between the first support 1 punched by the punching device 4 and the last support 1 punched by the punching device 4 shot by the camera device 3) is compared with the preset picture, and the parameter difference is obtained by comparing the drill profile parameters in the preset picture with the drill profile parameters in the real-time picture shot by the camera device 3, and the parameter difference is compared with the preset threshold value. If the preset threshold value is exceeded, it is considered that the hole position accuracy is unqualified. In this embodiment, there are multiple comparison methods. For example, when the captured image is a drill image between any two first supports 1 captured by the camera 3 during a drilling process of the drilling device 4, or a drill image between the first support 1 first drilled by the drilling device 4 and the first support 1 last drilled by the drilling device 4 captured by the camera 3 during a drilling process of the drilling device 4, in such captured drill images, there may be a situation where the captured drill image is divided into the same multiple segments by a plurality of first supports 1.

[0056] In this case, each segment can be extracted and compared with the preset picture (in this case, the preset picture is the drill picture between two adjacent first supports 1 taken by the camera device 3 during a standard drilling process of the support seat by the drilling device 4), or the picture of the drill during the entire drilling process taken by the camera device 3 can be compared with the preset picture (in this case, the preset picture is the drill picture between the first support 1 drilled first by the drilling device 4 and the last support 1 drilled last by the drilling device 4 taken by the camera device 3 during a standard drilling process of the support seat by the drilling device 4). Specific adjustments can be made according to actual conditions.

[0057] Of course, in other embodiments, there may also be a situation where, for example, when the captured image is an image of a drill bit between any two first supports 1 captured by the camera device 3 during a drilling process of the drilling device 4, or when the image of a drill bit between a first support 1 drilled first by the drilling device 4 and a first support 1 drilled last by the drilling device 4 captured by the camera device 3 during a drilling process of the drilling device 4, the captured drill bit image is divided into different multiple segments by a number of first supports 1. At this time, the preset image and comparison method can be adjusted according to the actual situation.

[0058] In another embodiment, the camera device 3 can be mounted on the mounting base 5 by means of an adjustment structure, and the adjustment structure is used to adjust the relative position of the camera device 3 on the mounting base 5, thereby accurately adjusting the position of the camera device 3.

[0059] Specifically, the adjustment structure includes an offset assembly, which includes an offset fixed base 6, a screw rod 7 and a moving member 8. The offset fixed base 6 is fixedly connected to the mounting base 5 through a connecting assembly, and the connecting assembly can be a bolt, a rivet, a fixing pin or other components used for connecting, which are not limited here; an offset chute is provided in the offset fixed base 6, and the offset chute is arranged in a direction parallel to the reference punching path, and the moving member 8 is movably arranged in the offset chute. Of course, in other embodiments, the offset chute may not be arranged in a direction parallel to the reference punching path, and the setting of the offset chute is sufficient as long as it can satisfy the movement of the moving member 8 in a direction parallel to the reference punching path. The two ends of the screw rod 7 are respectively rotatably connected to the offset fixed base 6, and the axial direction of the screw rod 7 is parallel to the reference punching path direction, and the screw rod 7 is passed through the moving member 8 and is threadedly connected thereto. Among them, the camera device is installed on the moving member 8. In this way, the left and right positions of the camera device 3 (that is, the position in the direction parallel to the reference punching path) can be adjusted by rotating the screw rod 7.

[0060] Furthermore, a lifting assembly is provided between the camera device 3 and the mobile component 8, and the lifting assembly includes a lifting fixture, a device fixture 9 and a lifting locking member 10. The camera device 3 is connected to the device fixture 9, and the device fixture 9 is slidably connected to the lifting fixture along the optical axis direction of the lens. The lifting locking member 10 is respectively connected to the lifting fixture and the device fixture 9, and is used to lock the relative positions of the lifting fixture and the device fixture 9. Among them, the lifting fixture can be the above-mentioned mobile component 8, or the lifting fixture can be detachably arranged on the mobile component 8, which is not limited here; in the present embodiment, the lifting fixture is the mobile component 8.

[0061] For details, see Figure 2 , a lifting guide groove arranged along the optical axis direction of the lens is provided on the lifting fixture, and the device fixture 9 is slidably connected in the lifting guide groove. A locking groove is provided on the side wall of the lifting guide groove, and a locking part extending into the locking groove is convexly provided on the device fixture 9, and the locking part can move along the optical axis direction of the lens in the locking groove with the device fixture 9. Locking holes corresponding to the lifting locking member 10 are respectively provided on the two side walls of the locking groove, and a plurality of adjustment holes arranged along the optical axis direction of the lens are provided on the device fixture 9. The lifting locking member 10 is penetrated by two locking holes and one of the adjustment holes to lock the relative position of the lifting fixture and the device fixture 9; and the lifting locking member 10 can be withdrawn from the adjustment hole and at least one locking hole to adjust the relative position of the lifting fixture and the device fixture 9.

[0067] When the heliostat main beam processing equipment provided in this embodiment is used, the main beam 11 is placed on the drilling machine base 2 to process multiple groups of holes simultaneously (that is, multiple drilling devices 4 simultaneously drill holes in the corresponding first support 1 in the support seat), and the camera device is fixed to a specified position on the drilling machine base 2 through the mounting seat 5.
