Description

Technical Field

[0001] This utility model relates to the technical field of pipeline network testing equipment, and in particular to a sewage culvert dredging and testing device. Background Technology

[0002] Currently, during the design phase of dredging pipeline networks, the spacing between inspection wells is generally between 50-80 meters to facilitate the inspection and maintenance of underground pipelines. However, difficult sections with larger well spacing are frequently encountered, especially in old pipeline networks and mountainous urban pipeline networks.

[0003] Traditional pipeline inspection equipment cannot perform comprehensive inspection of pipelines with long manhole spacing. This is mainly because the inspection equipment is inconvenient to move inside the pipeline, and the propeller of conventional spiral propulsion inspection equipment is easily entangled inside the pipeline, making it impossible to continue the inspection. There is an urgent need for a sewage culvert dredging and inspection device. Utility Model Content

[0004] This utility model provides a sewage culvert dredging and detection device to solve the problem that traditional pipeline detection equipment in the prior art cannot perform all-round detection of pipelines with long manhole spacing. This is mainly because the detection equipment is inconvenient to move inside the pipeline, and the propeller of conventional spiral propulsion detection equipment is easily entangled inside the pipeline, making it impossible to continue to move forward for detection.

[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0006] A sewage culvert dredging and detection device includes:

[0007] The central inspection vessel frame and the floating propulsion units installed on both sides of the central inspection vessel frame;

[0008] The central detection frame includes a reinforcing frame and an electrical compartment at the rear end of the reinforcing frame. A camera is installed at the front end of the reinforcing frame, and a sonar unit is installed at the lower end of the reinforcing frame.

[0009] The buoy propulsion unit includes hollow buoys installed on both sides of the reinforcing frame and a pump-jet propulsion unit installed at the rear end inside the hollow buoy.

[0010] In one specific implementation, high beam spotlights and low beam spotlights are respectively installed at the front ends of the floating hull propulsion sections on both sides of the central detection vessel frame.

[0011] In one specific implementation, the reinforcing frame includes a channel steel bar and a front drag hook installed at the front end of the channel steel bar, and a tail hook is provided at the rear end of the channel steel bar.

[0012] In one specific implementation, the electrical compartment includes an electrical compartment mounted on the upper end face of the channel steel bar and transmission lines electrically connected to the electrical compartment.

[0013] In one specific implementation, the sonar unit includes a mounting bracket fixedly welded to the lower end face of the channel steel bar and a ring scan sonar mounted on the mounting bracket.

[0014] In one specific implementation, the cavity float includes a body and a removable cover plate mounted on the upper part of the body.

[0015] In one specific implementation, the front end of the cabin is a pointed structure, the rear end of the cabin is a flat structure, and a tail nozzle is provided at the rear end of the cabin.

[0016] In one specific implementation, the pump-jet propulsion unit is fixedly installed at the rear end inside the cabin, with the nozzle of the pump-jet propulsion unit protruding from the tail nozzle.

[0017] The beneficial effects of this utility model are:

[0018] The floating pod propulsion units are installed on both sides of the central inspection vessel frame. The compact structure facilitates the insertion and removal of pipes from the inspection well using hoisting equipment. Meanwhile, a pump-jet propulsion unit is installed at the rear end of the hollow floating pod. Compared with traditional inspection equipment that uses conventional propulsion, there is no propeller entanglement, making it easier to move and inspect inside the pipe. Cameras and sonar units are installed on the reinforced frame, enabling comprehensive inspection of the conditions inside the pipe and transmitting information to the ground through the electrical compartment.
