The following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings, and the present invention is not limited by the following embodiments, and the embodiments can be determined according to the technical solutions and practical situations of the present invention. In the description, certain terminology is used herein for reference only and is not meant to be limiting.
Among them, the so-called sensor positioning structure is a space where a sensor is mounted, which can be obtained by deforming a foam or removing/adding some material. The foam outer surface means a region ranging from the foam outer surface to the foam inner surface, and is not limited to the plane of the outer surface.
As shown in fig. 1, the flexible intelligent pipe cleaner of the invention is mainly composed of a main cavity 1, a primary foaming body 2 and a secondary foaming body 3 which are nested layer by layer. The sensor positioning structure is arranged on the outer surface of the primary foaming body, and/or the sensor positioning structure is arranged in any one of the secondary foaming body and the primary foaming body, and/or the sensor positioning structure is arranged on the outer surface of the secondary foaming body. The sensor positioning structure is a groove or a hole. Almost all thermoset and thermoplastic plastics can be made into foams, and commonly used resins are polystyrene, polyurethane, polyvinyl chloride, polyethylene, urea formaldehyde, phenol formaldehyde, and the like. The primary foam body 2 and the secondary foam body 2 are one or more of the above foaming materials.

The bottom end cover is provided with an annular structure extending outwards, a plurality of wire passing holes are uniformly formed in the side face of the annular structure, and a lead passes through the annular wire passing holes through a lead sealing plug and is directly connected with an electric connector fixed on the rectangular via hole of the bottom end cover. Specifically, the main cavity is used for accommodating electronic equipment for collecting and storing data. A protruding annular structure extends outwards from the bottom end cover, and a plurality of annular wire passing holes are distributed in the side face of the protruding annular structure. An output lead of the sensor passes through the wire passing hole through the lead sealing plug and is directly connected with an electric connector arranged on the rectangular via hole at the bottom of the bottom side end cover, and the electric connector is connected with the electronic equipment in the main cavity so as to realize communication between the sensor and the electronic equipment. And sealing the lead, the electric connector and the bottom side end cover in the middle cavity of the annular structure by injecting epoxy resin. The main cavity is used as a carrier of electronic equipment, the diameter of the main cavity is far smaller than the inner diameter of the pipeline, and the sealing performance is good. The whole body can be made of plastic materials such as polytetrafluoroethylene and the like or stainless steel materials.
The end face of the top side end cover is exposed out of the secondary foaming body 3, and a sensor positioning structure is arranged near the top side end cover of the primary foaming body 2.
As shown in fig. 2 and 4, a primary foam body is formed by primary foaming outside the main cavity, the outer diameter of the primary foam body is about 30-40mm away from the outer diameter of the pipeline, and the length of the primary foam body can be slightly larger than the length of the shell of the cabin body but the annular structure of the bottom end cover is ensured to be completely exposed. And a plurality of sensor mounting holes or grooves are uniformly prefabricated on the outer surface of the primary foaming body near the top side end cover in the circumferential direction and used for positioning and arranging the sensors. The sensor positioning structure is provided with a non-contact sensor for detecting the pipe wall. The sensor is installed and wired after primary foaming.
As shown in fig. 3, the outer end face of the top end cover is provided with a hanging ring through threads so as to facilitate the handling and traction of the cleaning pig.
