[0020] The utility model will be further explained in connection with the drawings and specific embodiment.

[0021] It should be noted that in the following description, the terms "front," "rear," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. Example 1

[0022] like Figure 1 As shown, the underwater narrow pipe detection equipment involved in this embodiment includes an underwater detector 1, a collision protection ring 2, a waterproof umbrella 3, a first umbrella rib 4, a second umbrella rib 6, a sliding ring 8, a fixing part 9, a cable 11, a net sleeve 12, and a connecting line 13.

[0023] An underwater detector 1 is installed at the front end of the fixed part 9 to collect data inside the pipeline. The underwater detector 1 includes, but is not limited to, pipeline inspection equipment such as underwater cameras, sonar, and hydrophones. The underwater camera uses the collected image data to determine the type of dirt inside the pipeline, as well as aging and leakage points. A shock-absorbing ring 2 is installed at the front end of the underwater detector 1 to protect it from impacts. The cable 11 (such as an umbilical cable) extending from the rear end of the underwater detector 1 passes through the fixed part 9. A sliding ring 8 is fitted around the outside of the fixed part 9 and moves back and forth along the fixed part 9. Multiple first umbrella ribs 4 are hinged at equal intervals to the outer periphery of the shock-absorbing ring 2 or the front end of the underwater detector 1. Correspondingly, multiple second umbrella ribs 6 are hinged at equal intervals to the outer periphery of the sliding ring 8. The free ends of the second umbrella ribs 6 are hinged to the first umbrella ribs 4. A waterproof umbrella 3 is fixed to the outside of the first umbrella ribs 4. A net sleeve 12 is fixedly fitted around the outside of the cable 11 at the rear end of the fixed part 9. The net sleeve 12 is connected to the sliding ring 8 through multiple ring-shaped connecting lines 13 that are set at equal intervals upwards.

[0024] The underwater narrow pipe inspection device involved in this embodiment also includes a float 7, which is fixed to the side of the fixing part 9 near the waterproof umbrella 3. The design of the float 7 ensures that the underwater narrow pipe inspection device is positioned as close as possible to the center of the pipe during use, thus guaranteeing the accuracy of the collected data.

[0025] As one implementation, the fixing part 9 is a fixing tube, and the cable 11 passes through the cavity of the fixing tube. The inner diameter of the cavity of the fixing tube is smaller than the outer diameter of the net sleeve 12, thus controlling the maximum diameter of the waterproof umbrella 3 when it is opened. Figure 2As shown, in another implementation, the fixing part 9 is a fixing frame, which includes a first ring 901, a connecting rod 902, and a second ring 903. The first ring 901 and the second ring 903 are connected and fixed by multiple connecting rods 902. There are at least three connecting rods 902 arranged in a ring at equal intervals. The cable 11 passes through the first ring 901 and the second ring 903 in sequence. The underwater detector 1 is fixed to the front side of the first ring 901, and the float 7 is fixed to the rear side of the first ring 901. Further, a cable locking sleeve 10 is fixed to the rear side of the second ring 903. The cable 11 passes through the central hole of the cable locking sleeve 10. The inner diameter of the central hole of the cable locking sleeve 10 is smaller than the outer diameter of the net sleeve 12, which controls the maximum diameter of the waterproof umbrella 3 when it is opened.

[0026] The first umbrella rib 4 can be fixed to the outer periphery of the anti-collision ring 2, or it can be fixed to the outer periphery of the front end of the underwater detector 1. For ease of installation, the first fixing method is adopted, such as... Figure 3 As shown, specifically: the anti-collision guard ring 2 includes a hollow guard ring 201 and a first umbrella rib hinge seat 202. Multiple first umbrella rib hinge seats 202 are evenly spaced around the outer periphery of the hollow guard ring 201. Any one of the first umbrella rib hinge seats 202 is hinged to the front end of a first umbrella rib 4. Correspondingly, as... Figure 4 As shown, the sliding ring 8 includes a circular ring 801, side ears 802, and a second umbrella rib hinge seat 803. Multiple side ears 802 and multiple second umbrella rib hinge seats 803 are fixed in a ring around the outer periphery of the circular ring 801. The rear end of the second umbrella rib 6 is hinged to a second umbrella rib hinge seat 803, and the rear end of the first umbrella rib 4 is hinged to the corresponding front end of the second umbrella rib 6.

[0027] The underwater narrow pipe inspection device involved in this embodiment also includes a crash wheel 5. The crash wheel 5 is fixed to the free end of the first umbrella rib 4, which can prevent the device from being bumped and play a certain guiding role. The free end of the second umbrella rib 6 can be hinged to the middle of the first umbrella rib 4 or to the free end of the first umbrella rib 4. Preferably, the free end of the second umbrella rib 6 is hinged to the free end of the first umbrella rib 4, and the crash wheel 5 is installed at the hinge. This method can provide sufficient support for the crash wheel 5, making it easy for it to slide on the inner wall of the pipe.

[0028] The specific usage process of the underwater narrow pipe detection equipment involved in this embodiment is as follows: The pipe detection equipment is lowered into the pipe. Under the combined action of water flow and tension, the waterproof umbrella 3 is partially unfolded. The pipe detector moves forward along the water flow direction. The cable 11 is lowered at a constant speed to control the underwater detector 1 to move at a constant speed to collect relevant data inside the pipe. During retrieval, the cable 11 is pulled backward, and the net sleeve 12 moves backward with the cable 11. The sliding ring 8 is pulled backward through the connecting line 13, and the sliding ring 8 moves backward along the fixed frame 9, causing the waterproof umbrella 3 to retract. When the pipe detection equipment is lowered into the pipe, under the action of gravity, the cable 11 and the net sleeve 12 are in a backward-pulled state, and the waterproof umbrella 3 is retracted and folded, with the overall diameter at its smallest, which can be used for deployment in narrow entrances. The anti-collision wheel 5 is located on the outermost side of the equipment, which can prevent the equipment from being bumped and play a certain guiding role.

[0029] When pipeline inspection equipment is performing inspection operations, it is mostly in an extended state due to the action of water flow. However, when inspecting main pipelines, it may encounter branch pipelines. These branch pipelines are often narrower, and the water flow through them is accelerated and turbulent. Conventional pipeline inspection equipment may become uncontrollably stuck inside the branch pipelines, causing the equipment to become jammed. Figure 7 As shown, this utility model sets the maximum diameter when unfolded, so that when the equipment passes through a branch, the unfolded waterproof umbrella 3 stops the equipment at the entrance of the branch pipe, temporarily blocking the water flow to the branch. The waterproof umbrella 3 is pulled out of the branch pipe by pulling the cable 11, and then the speed of lowering the cable is accelerated to expand the unfolding angle of the waterproof umbrella 3, thereby increasing the forward speed of the equipment in the main pipeline. It uses inertia to quickly pass through the branch and continue to move forward.
