[0018] Example 1

[0019] See also Figures 1 to 4, is the first embodiment of the utility model, which provides a technical solution: an underwater structure detection device, including a fixing ring 1, a lifting ring 2, a detection camera 3 and a lifting rope 4, the fixing ring 1 is sleeved and fixed on the top area of ​​the structure 6, the lifting ring 2 is movably sleeved on the bottom area of ​​the structure 6, the fixing ring 1 and the lifting ring 2 are connected by a plurality of lifting ropes 4, a T-shaped installation notch 21 corresponding to the detection camera 3 is opened on the surface of the lifting ring 2, the detection camera 3 is installed in the T-shaped installation notch 21, a camera lens 33 is arranged on one side surface of the detection camera 3, and the camera lens 33 is embedded in the inner end of the T-shaped installation notch 21. In actual use, the operator needs to fix the fixing ring 1 on the area where the top of the structure 6 is above the water surface, and then lift the lifting ring 2 to the area where the bottom of the structure 6 is underwater through a plurality of lifting ropes 4, so as to install the lifting ring 2 on the lifting ring 2. The multiple detection cameras 3 are installed to perform visual image detection on the underwater part of the structure 6, that is, to record the image of the underwater part of the structure 6. These images can be used to judge whether the underwater part of the structure 6 is damaged or abnormal. It also includes a limit plate 71, an L-shaped base block 72 and a limit structure 73. The L-shaped base block 72 is welded and fixed to the top surface of the limit plate 71. The upper and lower surfaces of the lifting ring 2 are provided with stable sockets 22 that are connected to the T-shaped mounting notch 21. The limit plate 71 is inserted into the two sockets 22, and the limit plate 71 passes through the T-shaped mounting notch 21. The detection camera 3 is on the inner side of the limit plate 71, and the limit plate 71 can be used to block and limit the detection camera 3. Later, the limit plate 71 only needs to be pulled out to realize the rapid disassembly and assembly of the detection camera 3. The L-shaped base block 72 is stuck on the top surface of the lifting ring 2 through the limit structure 73.

[0020] Among them, the bottom end of the L-shaped base block 72 extends to the outer surface of the lifting ring 2, and the limiting structure 73 includes an inner groove 732 opened inside the L-shaped base block 72, and a spring 734 and a triangular clamping block 735 are arranged in the inner groove 732. A clamping hole 23 corresponding to the triangular clamping block 735 is opened on the outer surface of the lifting ring 2, and the triangular clamping block 735 is movably installed in the inner groove 732 through the spring 734, and the end of the triangular clamping block 735 passes through the inner side of the L-shaped base block 72 and is clamped into the clamping hole 23 to realize the clamping and limiting of the L-shaped base block 72, so that the limiting plug plate 71 and the L-shaped base block 72 can be stably limited during daily use, thereby ensuring the limiting stability of the limiting plug plate 71 on the detection camera 3, and a pull rod 733 is fixed to the other side surface of the triangular clamping block 735, and the pull rod The end of 733 passes through the outside of the L-shaped base block 72 and is fixed with a T-shaped pull block 731, which is convenient for subsequent operators to pull the triangular clamping block 735 into the inner groove 732 through the T-shaped pull block 731. If the detection camera 3 is to be removed later, it is only necessary to pull the T-shaped pull block 731 first, so that the pull rod 733 pulls the triangular clamping block 735 toward the inner groove 732, and the spring 734 is gradually compressed until the end of the triangular clamping block 735 moves out of the clamping hole 23, so that the triangular clamping block 735 can release the limit of the L-shaped base block 72.

In the absence of the blocking limit of the limit plug plate 71, the detection camera 3 can be directly removed from the T-shaped installation notch 21 for inspection and maintenance or data transfer.

[0021] One end of the spring 734 abuts against the inner wall of the inner groove 732 , and the other end of the spring 734 is fixedly connected to the triangular clamping block 735 , thereby achieving stable installation of the spring 734 and the triangular clamping block 735 .

[0022] Among them, the inner surface of the L-shaped base block 72 is provided with a pop-up hole connected to the inner groove 732, and the pop-up hole corresponds to the triangular clamping block 735, so that the triangular clamping block 735 can be ejected smoothly. The outer surface of the L-shaped base block 72 is provided with a rod hole connected to the inner groove 732, and the rod hole corresponds to the pull rod 733, so that the pull rod 733 can pass through smoothly.

[0025] Specifically, a rubber pad 31 is installed on the other side surface of the detection camera 3, and a plurality of integrated circular protrusions 32 are provided on one side surface of the rubber pad 31, both of which are made of rubber material and will undergo elastic deformation when squeezed. The circular protrusions 32 are in squeeze contact with the limiting plug plate 71, which can ensure the installation stability of the detection camera 3, so that the detection camera 3 can maintain its own stability due to the tight contact between the circular protrusions 32 and the limiting plug plate 71.

[0026] Among them, the other side surface of the rubber pad 31 is provided with multiple integrated T-shaped rubber heads 34, both of which are made of rubber material and will undergo elastic deformation when squeezed. The other side surface of the detection camera 3 is provided with a T-shaped slot 35 corresponding to the T-shaped rubber head 34, and the T-shaped rubber head 34 is embedded in the T-shaped slot 35 to achieve stable installation of the rubber pad 31.
