The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The embodiment of the present invention provides a shaft branch pipe detection device, such as Figure 1-3As shown, it includes: a frame 1, the frame 1 includes a first side plate 11 and a second side plate 12 arranged opposite to each other, and a top plate 13 connecting the top ends of the first side plate 11 and the second side plate 12; a mounting assembly 2 rotatably mounted between the first side plate 11 and the second side plate 12; a sonar 3 fixedly mounted on the mounting assembly 2, used to detect the branch pipe parameters; a central processing unit arranged on the frame 1, the sonar 3 is communicatively connected with the central processing unit, the branch pipe parameters collected by the sonar 3 are processed by the central processing unit and then transmitted to a remote terminal device through a cable, and the remote terminal device uploads the branch pipe data to a cloud server for storage; and a limiting mechanism 4 arranged between the frame 1 and the mounting assembly 2, used to lock the mounting assembly 2 to the frame 1 to fix the rotation angle of the mounting assembly 2, and also used to unlock the mounting assembly 2 and the frame 1 to adjust the rotation angle of the mounting assembly 2.

[0023] In this embodiment, the shaft branch pipe detection device includes a frame 1, a mounting assembly 2, a sonar 3 and a limiting mechanism 4. Specifically, the frame 1 includes a first side panel 11 and a second side panel 12 that are arranged opposite to each other, and a top panel 13 connecting the top ends of the first side panel 11 and the second side panel 12, and may also include a back panel 14 connecting the first side panel 11 and the second side panel 12 to reinforce the connection stability between the first side panel 11 and the second side panel 12. The mounting assembly 2 is rotatably mounted between the first side panel 11 and the second side panel 12, and is used to install a sonar 3 that can detect branch pipe parameters. The limiting mechanism 4 is arranged between the frame 1 and the mounting assembly 2, and is used to lock the mounting assembly 2 to the frame 1 to fix the rotation angle of the mounting assembly 2, and is also used to unlock the mounting assembly 2 from the frame 1 to adjust the rotation angle of the mounting assembly 2.

[0024] Among them, Sonar 3 is an electronic device that uses the propagation characteristics of sound waves underwater to complete underwater detection and communication tasks through electroacoustic conversion and information processing. The branch pipe parameters include the inner diameter of the branch pipe, the length of the branch pipe, the orientation of the branch pipe, etc. Therefore, the use of Sonar 3 can replace the method of manual down-well inspection and avoid the risks of artificial underwater operations.

[0025] In actual use, the mounting assembly 2 with the sonar 3 fixedly mounted thereon can be rotated relative to the frame 1, and after being rotated to a position where the detection head of the sonar 3 is facing vertically downward, the mounting assembly 2 is locked on the frame 1 by the limiting mechanism 4 to fix the orientation of the sonar 3. Then, the vertical shaft branch pipe detection device adjusted for the first time is slowly lowered to the bottom of the shaft, and at the same time, the internal situation of the shaft is observed by using an external imaging display device connected to the sonar 3, and when the image of the branch pipe opening is displayed on the imaging display device, the orientation of the branch pipe opening is recorded, and the vertical shaft branch pipe detection device is taken out of the shaft to complete the work of determining the orientation of the branch pipe.

[0026] After obtaining the position of the branch pipe, the limit mechanism 4 is used to release the lock between the installation component 2 and the frame 1 to adjust the rotation angle of the installation component 2 to a horizontal position, that is, parallel to the length direction of the branch pipe, and then the limit mechanism 4 is used to re-lock the installation component 2 on the frame 1, so that the detection head of the sonar 3 is fixed in a horizontal position, and the vertical shaft branch pipe detection device is slowly lowered to the position of the branch pipe mouth again, so that the detection head of the sonar 3 is aligned with the branch pipe mouth, and the inner diameter of the branch pipe mouth and the length of the branch pipe and other parameters are obtained at the same time. The detection of the inner diameter and length parameters of the branch pipe is completed. The branch pipe parameters collected by the sonar 3 are processed by the central processor (not shown in the figure) and transmitted to the remote terminal device (such as a computer) through a cable (not shown in the figure), and the remote terminal device uploads the branch pipe data to the cloud server (not shown in the figure) for storage.
