[0034] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the following embodiments combine with the drawings to make specific description to the self-driven water supply pipeline detection device of the utility model, and it needs to be explained that the description of these embodiments is used to help understanding the utility model, but does not constitute the limitation to the utility model.

[0035] The specific implementation of the utility model will be described in detail in combination with the drawings and preferred embodiments.

[0036] As Figures 1-2The utility model provides a kind of self-driving water supply pipeline detection device, including head cabin 1, tail cabin 2 and multiple functional cabins 3 being arranged between head cabin 1 and tail cabin 2, they are all connected by tubular sealing mechanism 4 between each other, the tubular sealing mechanism 4 is used to provide passage for cable passing and realize the sealing between passage and cabin body;Fastening clamping mechanism 21 is provided at the end of tail cabin 2, power conversion unit 22 is provided inside, the fastening clamping mechanism 21 is used to provide pressure clamping for cable;Power mechanism 11 is provided at the end of head cabin 1, control unit is provided inside, corresponding function detection unit is provided in each functional cabin, for realizing the corresponding defect detection of water supply pipeline;The power conversion unit 22 is connected with external power supply by cable, realizes the power supply of control unit, power mechanism, function detection unit.This way, the connection between each cabin body is realized by tubular sealing mechanism, both electrical connection and communication connection between cabin bodies can be realized, and the sealing between cabin bodies can be ensured, while the split modular structure of robot can be realized, the function expansion and maintenance of robot are facilitated, in addition, external power supply is introduced by cable, to provide continuous and stable working power supply for robot, to guarantee the endurance of robot, to provide physical basis for larger range of water supply pipeline detection.

[0037] Specific as follows:

[0038] The overall structure of water supply pipeline detection device is split, cabin bodies are connected together by tubular sealing mechanism, instead of integral structure, so we set power mechanism 11 on the end of head cabin 1, to facilitate traction other cabin bodies in water supply pipeline, the power mechanism 11 can be built by multiple propellers, and visual detection unit such as camera 12, illuminating lamp 13 etc. can also be assembled on the top of head cabin 1, to collect image information inside water supply pipeline, to analyze defect conditions such as rust, scale etc. inside pipeline by image processing calculation, three-axis gyroscope is assembled on internal control unit, to detect the attitude information of robot itself, to obtain the relative position of water supply pipeline detection device inside pipeline by analysis, to facilitate attitude adjustment and progress control etc.

[0039] As the power supply of water supply pipeline detection device comes from external power supply, and electric energy is delivered to each module unit by cable, so cable will be subjected to certain tension in movement process, so we set clamping mechanism with tensile capacity in tail cabin, to avoid cable being pulled out of water supply pipeline detection device in movement process, to reduce the influence of cable tension on movement of water supply pipeline detection device.

[0040] As Figure 3As shown, the tubular sealing mechanism 4 is arranged between the tail cabin 2 and the functional cabin 3, between two adjacent functional cabins 3, and between the front end of the functional cabin 3 and the head cabin 1, and includes a wire passing column pipe 41 arranged inside the cabin body, the inside of the wire passing column pipe 41 is provided for the cable 5 to pass through, one end is provided with a step, so that the end part forms two pipes with different outer diameters, the outside of the small size part is sleeved with a connecting pipe 6, the large size part is threadedly connected with an end cover, the inside of the connecting pipe 6 is also provided for the cable 5 to pass through, so that the connecting pipe 6 and the wire passing column pipe 41 connected in communication can lead the external cable to the inside of the cabin body, and a ring-shaped protrusion 42 can be arranged on the outside of the small size part along the circumference thereof, the sleeved connecting pipe 6 can adopt a hose structure to increase the tightness and firmness of the connection between the connecting pipe 6 and the wire passing column pipe 41, and to prepare for subsequent sealing.

[0041] The end cover is matched with the end part of the cabin body, a first threaded hole is arranged at the central position of the end cover for the connecting pipe to pass through, the first threaded hole is threadedly connected with the large size part, one end of the end cover is provided with a first annular stopper, the first annular stopper is in contact with the end face of the first annular protrusion, so that after the connecting pipe 6 is sleeved on the small size part, the end cover is screwed on the large size part, as the wire passing column pipe 41 is gradually screwed into the first threaded hole, the first annular stopper gradually abuts against the ring-shaped protrusion 42, so that the connecting pipe 6 is clamped between the ring-shaped protrusion 42 and the first annular stopper, to achieve the sealing between the cabin body and the connecting pipe 6.

[0042] For the tail end of the tail cabin, it is not necessary to connect other cabin bodies, only the cable 5 needs to be connected, so it is not necessary to seal with the tubular sealing mechanism, and we design a nested sealing mechanism 7, which includes an end cover, a first sealing sleeve 71 and a first locking nut 72 which are nested in sequence and are sleeved on the cable 5, a through hole is arranged at the central position of the end cover for the cable 5 to pass through, an extension pipe 73 is arranged outward along the axial direction of the through hole, the outside of the extension pipe 73 is threadedly connected with the first locking nut 72; the first sealing sleeve 71 is sleeved on the outside of the cable, one end of the first sealing sleeve 71 is in the shape of a circular truncated cone, the small head part of the circular truncated cone is inserted into the inside of the extension pipe 73, the end face of the large head part is in contact with a second annular stopper of the first locking nut 72, and the inner circle of the second annular stopper is matched with the outer diameter of the cable 5.

[0043] In assembly, the first sealing sleeve 71 is first sleeved on the cable, then the end cover and the first locking nut 72 are respectively sleeved on both sides of the first sealing sleeve 71, the small head part of the first sealing sleeve is then inserted into the inside of the extension pipe, and finally the end cover is screwed onto the extension pipe 73, as the first locking nut 72 is gradually screwed in, the second annular stopper abuts against the large head part in the shape of a circular truncated cone, so that the first sealing sleeve 71 is gradually extruded into the inside of the extension pipe 73, to achieve the sealing between the cable and the tail cabin.

[0044] AsFigure 4 As shown, the fastening clamping mechanism 21 includes an upper clamping block 211 and a lower clamping block 212 that cooperate with each other inside the tail compartment. A notch for the cable 5 to pass through is provided in the center between the upper clamping block 211 and the lower clamping block 212. The inner size of the notch is smaller than the outer size of the cable 5. Multiple threaded holes are provided on both sides of the upper clamping block 211 and the lower clamping block 212. Bolts pass through the corresponding threaded holes to fix the upper clamping block 211 and the lower clamping block 212 to the horizontal plate of the T-shaped bracket 213. The vertical plate of the T-shaped bracket 213 is fixed to the end of the tail compartment.

[0045] We can design the shape of the vertical plate to match the inner cavity of the cabin, such as a circle, with a through hole in the center for the cable 5 to pass through. The vertical plate can then be assembled to the end of the stern cabin by bolts. Since the notch between the upper clamping block 211 and the lower clamping block 212 is smaller than the cable, the cable 5 will be firmly clamped between the clamping plates after the bolts are assembled, achieving pressure clamping.

[0046] Considering that the power conversion unit 22 is installed inside the tail compartment, we can appropriately lengthen the horizontal plate to facilitate the installation of the power conversion unit 22 to the end of the horizontal plate. The corresponding power conversion control board 23 is also installed on the horizontal plate, while the clamping block is installed close to the power conversion unit 22 at other positions on the horizontal plate.

[0047] The specific number and detection functions of functional compartment 3 can be determined according to actual needs. For example, if leak detection is required, one of the functional compartments can be set as a leak detection compartment, and leak detection can be achieved with the help of a hydrophone.

[0048] Considering the working principle of hydrophones, such as Figure 5 As shown, we designed the side wall of the cylindrical cabin near the tail end as a hollow structure. Inside the cylindrical cabin, the hollow area and the non-hollow area are sealed and isolated by the isolation plate 31. The isolation plate 31 can be a circular plate that cooperates with the cylindrical cabin. The seal between the isolation plate 31 and the cylindrical cabin is achieved by multiple sealing rings.

[0049] For the hollowed-out area, a hydrophone 32 is installed on the isolation plate 31;

[0050] For non-perforated areas, an electromagnetic generator 33 and a leak detection control circuit board 34 are installed on the isolation plate 31. The electromagnetic generator 33 is used to generate and emit electromagnetic waves of a preset frequency, which can be used in conjunction with a receiver on the ground to achieve precise positioning of the water supply pipeline detection device, thereby determining the precise location of the leak on the water supply pipeline.

[0051] The electromagnetic generator 33 has a columnar structure and is assembled inside the columnar frame by multiple clamps 35. The bottom surface of the columnar frame is assembled on the isolation plate 31, and its side wall is provided with a cut surface. A leak detection and control circuit board 34 is assembled on the cut surface.

[0052] The hydrophone 32 comprises a spherical detection end and a rod-shaped fixed end, and considering that the hydrophone 32 also needs to be sealed, the sealing structure thereof is similar to the sealing structure of the tail cabin and the cable, and a second threaded through hole through which the rod-shaped fixed end passes is arranged on the isolation plate 31, the second threaded through hole is in threaded cooperation with a second lock nut 36, the second lock nut 36 can adopt an external thread structure, a third annular stop piece is arranged on an end face of the second threaded through hole close to the spherical detection end, and a second sealing sleeve 37 is sleeved on the outer side of the rod-shaped fixed end, the second sealing sleeve 37 is the same in structure as the first sealing sleeve 71, is inserted into the inside of the second threaded through hole, and one end thereof is in the shape of a circular truncated cone, the small head portion of the circular truncated cone abuts against the third annular stop piece, and the large head portion is in contact with the second lock nut 36.

[0053] Similarly, during assembly, the rod-shaped fixed end of the hydrophone 32 is first inserted into the second threaded through hole, then the second sealing sleeve 37 is sleeved on the rod-shaped fixed end, the second sealing sleeve 37 is moved along the rod-shaped fixed end, the small head portion is inserted into the inside of the second threaded hole, finally the second lock nut 36 is screwed into the second threaded through hole, and thus the second sealing sleeve 37 is gradually extruded into the second threaded through hole, and the sealing of the hydrophone 32 is realized.

[0054] Although the specific embodiments of the present application are described above, those skilled in the art should understand that these are only examples, and various changes or modifications can be made to these embodiments without departing from the principles and essence of the present application, therefore, the protection scope of the present application is defined by the appended claims.
