[0026] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it is worth specifically explaining that the lifting assembly 4 includes a plurality of mounting frames a41, and the plurality of mounting frames a41 are symmetrically distributed and fixed to the top side wall of the bottom plate 1, and the side walls of one side of every two adjacent mounting frames a41 are rotatably connected with a bidirectional threaded rod 42, and a threaded sleeve 43 is threadedly connected to the external thread of the bidirectional threaded rod 42, and the threaded sleeve 43 is slidably connected to the inside of the mounting frame a41, and a support plate a44 is fixed to the side wall of one side of the bottom plate 1, and a servo motor a45 is fixed to the top side wall of the support plate a44, and one end of the output shaft of the servo motor a45 is coaxially fixed to one end of the bidirectional threaded rod 42; a plurality of mounting frames b46, and the plurality of mounting frames b46 are symmetrically distributed and fixed to the bottom side wall of the top plate 3, and one side of the mounting frame b46 is A guide rod 47 is fixed to the wall, and a mounting sleeve 48 is slidably sleeved on the outer surface of the guide rod 47. The mounting sleeve 48 is slidably connected to the inner side of the mounting frame b46. A scissor-type hinged frame 49 is hinged between the two mounting sleeves 48 and the two threaded sleeves 43. A plurality of symmetrically distributed telescopic rods 410 are fixed between the top plate 3 and the bottom plate 1. Through the setting of the lifting component 4, the height position of the viewing angle positioning camera 12 can be adjusted according to specific needs, so as to meet the image acquisition work needs at different high and low positions. In addition, the structure is simple and reliable, and it is convenient to flexibly adjust the viewing angle positioning camera 12 to meet the shooting positions and angle requirements of different visual detection positioning. It is highly practical and convenient for staff to operate and control.

[0027] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth specifically explaining that the rotating assembly 7 includes a driving shaft 71, which is rotatably connected to the side wall of one side of the top plate 3, one end of the driving shaft 71 is fixed to the side wall of the bottom end of the load-bearing ring 5, and two symmetrically distributed bearing seats 72 are fixed to the side wall of the bottom end of the top plate 3, and the two bearing seats 72 are internally connected with a driven shaft 73 that is rotatably connected, a worm gear 74 is tightly sleeved on the outer surface of the driving shaft 71, and a worm 75 is tightly sleeved on the outer surface of the driven shaft 73, and the worm 75 is meshingly connected with the worm gear 74, and two symmetrically distributed brackets 76 are fixed to the side wall of one side of the top plate 3, and a driving motor 77 is commonly fixed to the side wall of one side of the two brackets 76, and one end of the output shaft of the driving motor 77 is coaxially fixed with one end of the driven shaft 73.

Not only is the viewing angle positioning camera 12 flexible and convenient to adjust, but the adjustment method is also highly reliable, which can meet the requirements for multi-angle viewing angle acquisition and effectively solve the problem of limitations during use.

[0028] This solution has the following working process: when the height of the viewing angle positioning camera 12 needs to be adjusted, two servo motors a45 are driven simultaneously to make the bidirectional threaded rod 42 rotate synchronously, and the thread transmission effect between the bidirectional threaded rod 42 and the threaded sleeve 43 is used to cause the transmission effect of the scissor-type hinge frame 49 to make the installation sleeve 48 move along the installation frame b46 after being subjected to force, so that the top plate 3 moves upward under the force after being squeezed, so as to achieve the purpose of adjusting the height of the viewing angle camera. When the horizontal angle needs to be adjusted, the driven shaft 73 is driven by the driving motor 77 to rotate synchronously, with The movable worm 75 rotates synchronously, and the meshing transmission effect between the worm 75 and the worm wheel 74 is utilized to make the driving shaft 71 rotate synchronously, driving the load-bearing ring 5 to rotate synchronously, thereby driving the frame 6 and the perspective positioning camera 12 to operate, so as to achieve the purpose of adjusting the angle of the perspective positioning camera 12. When the horizontal position of the perspective positioning camera 12 needs to be adjusted, the lead screw 10 is driven by the servo motor b9 to rotate synchronously, and the transmission effect between the lead screw 10 and the wire sleeve 11 is utilized to cause the wire sleeve 11 to move along the frame 6, thereby driving the perspective positioning camera 12 to move horizontally synchronously.

[0029] According to the above working process, it can be known that: through the setting of the lifting component 4, the height position of the viewing angle positioning camera 12 can be adjusted according to specific needs, so as to meet the image acquisition work needs at different high and low positions, and the structure is simple and reliable, which is convenient for flexible adjustment of the viewing angle positioning camera 12 to meet the shooting positions and angle requirements of different visual detection positioning. It is highly practical and convenient for staff to operate and control. Through the setting of the rotating component 7, it can meet the viewing angle acquisition work needs at different angles and positions. The scope of application is relatively wide. Not only is the viewing angle positioning camera 12 flexible and convenient to adjust, but the adjustment method is also highly reliable, which can meet the multi-angle viewing angle acquisition work needs and effectively solve the problem of limitations during use.

[0030] Further as Figure 1 and Figure 2 As shown, it is worth specifically explaining that a support plate b8 is fixed to a side wall of one side of the frame 6, a servo motor b9 is fixed to the top side wall of the support plate b8, a screw rod 10 is rotatably connected to the inner side wall of the frame 6, one end of the output shaft of the servo motor b9 is coaxially fixed with one end of the screw rod 10, a threaded sleeve 11 is threadedly connected to the external thread of the screw rod 10, the thread sleeve 11 is slidably connected to the inner side of the frame 6, and a viewing angle positioning camera 12 is arranged on the top side wall of the thread sleeve 11. By arranging the screw rod 10 and the thread sleeve 11, the position of the viewing angle positioning camera 12 on the horizontal plane can be adjusted, so as to ensure that the viewing angle positioning camera 12 is not shaken when the position is adjusted, resulting in a poor viewing angle imaging effect, effectively ensuring the imaging effect of image acquisition, not only can meet various visual detection needs, but also there is no need to move the camera, thereby ensuring the stability of the camera's long-term operation.

[0031] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth mentioning that the projected area value of the top plate 3 is consistent with the projected area value of the bottom plate 1, two symmetrically distributed guide rods 13 are fixed to the bottom side wall of the frame 6, and an annular guide groove 14 is provided on the top side wall of the top plate 3. The guide rod 13 is slidably connected with the inside of the annular guide groove 14. By sliding the guide rod 13 in the annular guide groove 14, not only the stability of the frame 6 and the load-bearing ring 5 during operation is improved, but also the service life of the frame 6 and the load-bearing ring 5 is greatly enhanced.

[0032] Further as Figure 1 As shown, it is worth explaining in detail that the central axis of the load-bearing ring 5 is colinear with the central axis of the top plate 3, and one end of the guide rod 13 is set with a smooth arc surface. The smooth arc surface of the guide rod 13 can improve the stability and smoothness of the guide rod 13 when sliding in the annular guide groove 14, and avoid the guide rod 13 from getting stuck when sliding in the annular guide groove 14.

[0033] In summary: through the setting of the screw rod 10 and the screw sleeve 11, the position of the viewing angle positioning camera 12 on the horizontal plane can be adjusted, so as to ensure that the viewing angle positioning camera 12 is not shaken when the position is adjusted, resulting in poor viewing angle imaging effect, and effectively guaranteeing the imaging effect of image acquisition, which can not only meet various visual detection needs, but also do not need to move the camera, thereby ensuring the stability of the camera's long-term operation, and through the guide rod 13 sliding in the annular guide groove 14, not only the stability of the frame 6 and the load-bearing ring 5 during operation is improved, but also the service life of the frame 6 and the load-bearing ring 5 is greatly enhanced, and through the smooth arc surface setting of the guide rod 13, the stability and smoothness of the guide rod 13 when sliding in the annular guide groove 14 can be improved, and the guide rod 13 can be prevented from getting stuck when sliding in the annular guide groove 14.

[0034] The servo motor a45, the drive motor 77, the servo motor b9 and the viewing angle positioning camera 12 can all be purchased on the market.
