[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example 1:

[0041] See also Figures 1-6 , this embodiment provides the following technical solutions: a water conservancy project supervision video acquisition device, including an acquisition device body 1, the acquisition device body 1 includes a monitoring and transmission module, a fixed upper plate 2 is fixed to the bottom of the acquisition device body 1, and both sides of the fixed upper plate 2 are rotatably connected with side shafts 201, and a movable plate 202 is fixed to one side of the bottom end of the side shaft 201. The angle between the fixed upper plate 2 and the movable plate 202 is adjusted by a screw module, and a plurality of positioning holes are opened on the surface of the movable plate 202. By setting the fixed upper plate 2 and the movable plate 202 and rotating them through the side shaft 201, the angle between the two can be changed, so that it can better adapt to river banks or other installation positions with different angles, so that the acquisition device body 1 can maintain a better acquisition position and angle, maintain the stability of the equipment, and improve the application range of the acquisition device body 1.

[0042] The screw module includes a bearing plate 3, one end of the top of the movable plate 202 is fixed with a bearing plate 3, the other end of the top of the movable plate 202 is fixed with a bearing seat 302, one side of the bearing plate 3 is rotatably connected to a threaded rod 301, one end of the threaded rod 301 is fixed with a screw 308, the circumference of the threaded rod 301 is rotatably connected to the inner wall of the bearing seat 302, the circumference of the threaded rod 301 is threadedly connected with a threaded member 303, a limiting cylinder 304 is fixed at the groove on the circumference of the threaded member 303, a plurality of wing plates 305 are fixed on the circumference of the limiting cylinder 304, one end of the wing plate 305 is fixed with a connecting rod 306, one end of the connecting rod 306 is rotatably connected to a fixed bridge member 307, and the top of the fixed bridge member 307 is connected to the inner wall of the bearing seat 302. The bottom of the fixed upper plate 2 is fixed, and the threaded rod 301 is threadedly connected by the screw 308 and the limiting cylinder 304 fixes and limits the threaded member 303, so that the limiting cylinder 304 moves along the threaded rod 301 as it rotates. As the angle between the movement connecting rod 306 of the threaded member 303 and the wing plate 305 and the fixed bridge member 307 changes, the movable plate 202 is gradually pushed to change its position and the angle with the fixed upper plate 2, thereby facilitating the operation of the staff. At the same time, after installation, the staff can still rely on rotating the threaded rod 301 to change the angle of the movable plate 202, thereby improving user experience, facilitating the operation of the staff, and simplifying maintenance and angle changes after installation.

[0043] An auxiliary hole 4 is opened at the bottom of the fixed bridge 307. The depth of the auxiliary hole 4 is greater than the diameter of the threaded rod 301. Through the auxiliary hole 4, when the angle is not adjusted, the threaded rod 301 is located in the auxiliary hole 4 of the fixed bridge 307, which is convenient for storage and prevents interference, reducing the space required for transportation and reducing transportation costs.

[0044] A plurality of anti-skid grooves 5 are provided at the bottom of the fixed bridge 307, which increase the friction between the fixed bridge 307 and the movable plate 202 through the anti-skid grooves 5, thereby preventing the fixed upper plate 2 and the movable plate 202 from shaking left and right during storage and transportation, causing the rotating connection between the fixed bridge 307 and the connecting rod 306 and the wing plate 305 to loosen, thereby improving its service life.

[0045] A plurality of positioning screw holes 6 are provided in a linear array on both sides of the threaded rod 301 at the top of the movable plate 202. By providing the positioning screw holes 6 on both sides of the threaded rod 301 at the top of the movable plate 202, when the staff rotates the threaded rod 301 to adjust the angle between the movable plate 202 and the fixed upper plate 2, the position of the threaded member 303 on the threaded rod 301 changes accordingly. After the angle is adjusted appropriately, the staff uses the positioning screw holes 6 to screw multiple bolts upward from the bottom of the movable plate 202, so that the multiple bolts are respectively located at both ends of the threaded member 303, limiting the position of the threaded member 303 and preventing the position change caused by its self-spinning, thereby better limiting the angle and improving the stability of the screw module.

[0046] The screw 308 is covered with a rubber layer 8, and a plurality of transverse grooves are provided in a circumferential array on the surface of the rubber layer 8 to increase the friction between the palm of the worker and the rubber layer 8, making it easier for the worker to rotate and improving the user experience.

[0047] A plurality of resistance blocks 11 are fixed on the top of the movable plate 202, and a rubber pad 1101 is glued and fixed on the top of the resistance block 11 to prevent the fixed upper plate 2 from being deformed due to pressure during storage. The resistance blocks 11 and the rubber pad 1101 prevent one end of the fixed upper plate 2 from being suspended in the air.

[0048] Stable triangles 7 are fixed on both sides of the interference block 11, and the bottom of the stable triangle 7 is fixed to the top of the movable plate 202. Stable triangles 7 are fixed on both sides of the side shaft 201, and one side of the stable triangle 7 is fixed to the side of the movable plate 202, thereby increasing the fixing effect and improving its service life.

[0049] An additional panel 9 is fixed to the top of the fixed upper plate 2, and the top of the additional panel 9 is fixed to the bottom of the acquisition device body 1 to prevent the fixed upper plate 2 from being deformed due to the small contact area between the acquisition device body 1 and the additional panel 9.

[0050] A plurality of stabilizing ladders 10 are fixed to the back of the acquisition device body 1 , and the bottom of the stabilizing ladders 10 is fixed to the top of the added panel 9 to prevent the acquisition device body 1 from tilting during use and improve the fixing effect.

[0051] Example 2:

[0052] See also Figures 1-6 In this embodiment, staff deployed five sets of this video acquisition device for real-time monitoring of riprap slope protection operations during a riverbank reinforcement project on a section of the Yangtze River, using the disclosed method. The acquisition device body 1 utilized a Hikvision DS-2DE7230IW-A network camera (2 megapixels, 30x optical zoom). The fixed upper plate 2 and the additional panel 9 were welded from 10 mm thick Q235 steel plates. The on-site riverbank slope was 25°, and the operator installed the device according to the following process:

[0053] According to the terrain, the screw member 308 (40 mm diameter) covering the cross-striped rubber layer 8 rotates, driving the 45-gauge steel threaded rod 301 (4 mm pitch). The threaded rod drives the 304 stainless steel threaded member 303 to move horizontally, pushing the limiting cylinder 304 through the four sets of wing plates 305, which in turn connect the connecting rod 306 (150 mm long). This causes the fixed bridge 307 to generate thrust on the movable plate 202. The movable plate 202 rotates around the side shaft 201 (20 mm diameter) until it forms a 25° angle with the fixed upper plate 2, at which point the camera remains horizontal.

[0054] 8.8-grade high-strength bolts are screwed into the M10 positioning screw holes 6 (50 mm apart) at the top of the movable plate 202, tightening against the sides of the threaded member 303 to prevent vibration and displacement. Eight anti-slip grooves 5 (2 mm deep) at the bottom of the fixed bridge 307 engage the surface of the movable plate 202 to increase static friction. Four sets of stabilizing triangles 7 (5 mm thick) are welded to the connection between the side shaft 201 and the movable plate 202 to resist water impact and vibration. Two stabilizing ladders 10 (30 mm high) on the back of the camera are welded to the expansion panel 9 to suppress equipment pitch and roll.

[0055] During emergency storage, loosen the bolt and rotate the screw 308 in the opposite direction. The threaded rod 301 will retract into the auxiliary hole 4 (25 mm in diameter and 30 mm in depth) of the fixed bridge 307. The movable plate 202 will be reset to a horizontal state. The NBR rubber pad 1101 (3 mm thick) on the top of the resistance block 11 will buffer the pressure of the fixed upper plate 2, and the transportation volume will be reduced by 40%.

[0056] In extreme environments, such as heavy rain (wind speed of 12 m / s), the device remained stable on a 25° mud slope, with a camera offset angle of <0.5°. After 30 days of continuous operation, the screw mechanism showed no spin displacement (the pre-tightening force of the positioning bolts reached 120 Nm). Compared with traditional parallel base equipment: the installation and adjustment time was shortened from 15 minutes to 3 minutes, and the terrain adaptability slope range was expanded to 0-45°.

[0057] The working principle of the present invention is as follows: when the staff installs the collection equipment body 1, the screw member 308 is rotated according to the slope of the river bank to drive the threaded rod 301. The rubber layer 8 increases the friction between the staff's palm and the rubber layer 8, which is convenient for the staff to rotate, and drives the threaded member 303 to move axially along the threaded rod, pushing the limiting cylinder 304 and the wing plate 305 to link the connecting rod 306, so that the fixed bridge member 307 applies thrust to the movable plate 202; the movable plate 202 rotates around the side shaft member 201 until it forms an inclination angle that adapts to the terrain with the fixed upper plate 2. At this time, the collection equipment body 1 remains horizontal; after the angle is determined, the bolt is screwed in from bottom to top through the positioning screw hole 6 to resist the two ends of the threaded member 303 to prevent self-spin displacement; the rubber pad 1101 on the top of the contact block 11 buffers the pressure of the fixed upper plate when it is stored, and the stabilizing triangle member 7 strengthens the rigidity of the connection between the side shaft member 201 and the movable plate 202; the added panel 9 prevents the collection equipment body 1 and the added panel 9 The smaller contact area causes deformation of the fixed upper plate 2, and the stabilizing ladder 10 prevents the main body 1 of the collection equipment from tilting during use, ultimately achieving a firm grip and monitoring of the collection equipment on the inclined river bank, overcoming the terrain adaptability defects of the traditional parallel base. After installation, the staff can still rely on rotating the threaded rod 301 to change the angle of the movable plate 202, thereby improving user experience, facilitating staff operation, simplifying maintenance and angle changes after installation; the auxiliary hole 4 allows the threaded rod 301 to be located in the auxiliary hole 4 of the fixed bridge 307 when the angle is not adjusted, thereby facilitating storage, preventing conflict, and reducing the space required for transportation. The anti-slip groove 5 increases the friction between the fixed bridge 307 and the movable plate 202 to prevent the fixed upper plate 2 and the movable plate 202 from shaking left and right during storage and transportation, thereby preventing the rotating connection between the fixed bridge 307 and the connecting rod 306 and the wing plate 305 from loosening, thereby increasing its service life.

[0058] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
