A detection mechanism for leakage detection includes detection holes on the wall of a semi-circular hole in the housing, and multiple sets of detection holes are arranged circumferentially on the wall of the semi-circular hole in the housing. The detection holes are connected to the detection cavity, and each set of detection holes is provided with a detection component. And a sealing mechanism for temporary treatment of leaks, the sealing mechanism including a sealing component and an auxiliary pressing component for use in conjunction with the sealing component. The sealing component is provided in the sealing cavity of each of the two sets of housings, and the two sets of sealing components are sealed and connected by a connecting component. One set of housings is also provided with an actuating component for driving the sealing component to work.

[0006] As a further aspect of the present invention: one detection cavity is provided on each side of the sealing cavity.

[0007] As a further aspect of the present invention: the detection component includes a detection piece fixedly installed in the detection hole, the bottom of the detection piece has a concave arc-shaped structure, and two wires are also provided inside the detection piece. The bottom of the detection piece is provided with an absorbent cloth for connecting the two sets of wires.

[0008] As a further aspect of the present invention: the detection sheet is also provided with an electric heating wire for drying the absorbent cloth, and multiple sets of the electric heating wire are provided on both sides of the absorbent cloth.

[0009] As a further aspect of the present invention: the sealing component includes: A sealing box fixed inside the sealing cavity, wherein both the upper and lower ends of the sealing box are provided with connecting holes, and the end of the sealing box away from the sealing cavity has an opening; And an elastic sealing strip, which is fixedly installed inside the opening of the sealing box, forming a sealed cavity structure between the sealing box and the elastic sealing strip.

[0010] As a further aspect of the present invention: the connectivity component includes: A connecting block, one end of which is fixedly installed in one of the connecting holes, and the other end of which is provided with a sealing airbag, and the connecting block has an air guiding cavity. Through holes, multiple sets of through holes are opened at both ends of the connecting block, and the through holes are connected to the air guiding cavity inside the connecting block; And an air guide channel opened on the side wall of the connecting block, the air guide channel being used to seal the connection between the airbag and the cavity inside the connecting block.

[0011] As a further aspect of the present invention: the starting component includes an air pump fixedly installed on the housing, and the output end of the air pump is connected to one of the sealing boxes through a conduit.

[0012] As a further aspect of the present invention: the auxiliary component includes: A telescopic component is fixedly installed on the sealing box, and two sets of pressing rollers are symmetrically arranged on the telescopic end of the telescopic component; The take-up roller is rotatably installed inside the sealing box, and two sets of take-up rollers are symmetrically arranged inside the sealing box. A motor for driving the take-up roller to rotate is also provided inside the side wall of the sealing box. And an elastic pressing belt, one end of which is fixedly connected to the end of the sealing box, and the other end of which passes through the pressing roller and is fixedly connected to the winding roller.

[0013] As a further aspect of the present invention: two sets of the auxiliary components are symmetrically arranged inside the sealing box.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: In use, screws are used to connect the two sets of housings together. The pipe passes through the circular hole formed by the combination of the two sets of housings, and the traveling wheels press against the surface of the pipe. In practical applications, a set of long-distance pipeline leakage detection devices can be installed at certain intervals on the pipeline. The traveling wheels allow the entire device to move on the pipeline. During the movement, the detection components can detect the location of the leak in time. When the leak is detected, the traveling wheels will drive the entire device forward or backward a certain distance, making it easy to move the sealing chamber to the location of the leak. The starting component drives the sealing components to work, which can effectively seal the leak. The auxiliary components can further improve the sealing effect, preventing the leak from remaining in a state of disrepair before repair, and avoiding water waste. Once the sealing chamber is moved to the leak location, an air pump is used to introduce gas through a conduit into one set of sealing boxes. A connecting block ensures that both sets of sealing boxes are filled with gas. After the gas completely fills the cavity between the sealing box and the elastic sealing strip, it applies pressure to the elastic sealing strip, ensuring full contact between the strip and the pipe surface, thus achieving the sealing function. Once the elastic sealing strip is completely pressed onto the pipe surface, the air pump continues to operate, allowing some gas to enter the sealing airbag through the air guide channel. This causes the sealing airbag to inflate, and the inflated airbag then presses against the connecting block and the connecting hole. The connection between the two sets of sealing boxes is fully filled to improve the sealing performance between them. Finally, the auxiliary components start to work. Specifically, the telescopic component drives the pressing roller to press the elastic sealing strip, while the motor drives the winding roller to rotate and wind up the elastic pressing strip, so that the elastic pressing strip is completely pressed onto the elastic sealing strip. Through the coordinated setting of the two sets of elastic pressing strips, one side of the elastic sealing strip can be fully pressed. Through the mutual cooperation of the auxiliary components in the two sets of sealing boxes, the elastic sealing strip can be pressed in the circumferential direction, further improving the sealing effect. This invention, through the coordinated design of the detection mechanism and the sealing mechanism, avoids the problem that existing long-distance pipeline leakage detection devices cannot promptly and temporarily seal the leak when a leak is detected, which easily leads to water waste.

[0028] Please see Figures 1-8 This invention provides a long-distance pipeline leakage detection device, which includes: The housing 1 has a detection chamber 23 and a sealing chamber 14 respectively, and a semi-circular hole is provided on the housing 1. There are two sets of housing 1, which are detachably connected. The two sets of housing 1 are combined to form a circular hole for the pipe to pass through. Multiple sets of walking wheels 3 are also provided in the semi-circular hole of the housing 1. The walking wheels 3 are electric wheels. The detection mechanism for leakage detection includes a detection hole 13 opened on the wall of a semi-circular hole in the housing 1, and multiple sets of detection holes 13 are arranged circumferentially on the wall of the semi-circular hole in the housing 1. The detection holes 13 are connected to the detection cavity 23, and each set of detection holes 13 is provided with a detection component. And a sealing mechanism for temporary treatment of leakage, the sealing mechanism including a sealing component and an auxiliary pressing component for use in conjunction with the sealing component. The sealing component is provided in the sealing cavity 14 of each of the two sets of housings 1, and the two sets of sealing components are sealed and connected by a connecting component. One set of housings 1 is also provided with an actuating component for driving the sealing component to work.

[0029] In an embodiment of the present invention, the long-distance pipeline leakage detection device is suitable for water transport pipelines. In use, two sets of housings 1 are joined together using screws. The pipeline passes through the circular hole formed by the combined housings 1, and the traveling wheels 3 press against the surface of the pipeline. In practical applications, a set of long-distance pipeline leakage detection devices can be installed at certain intervals on the pipeline. The traveling wheels 3 allow the entire device to move along the pipeline. During movement, the detection components can promptly detect the location of leaks. Once a leak is detected, the traveling wheels 3 will drive the entire device forward or backward. By moving the sealing cavity 14 a certain distance back, it is easy to move the sealing cavity 14 to the location of the leak. The actuating component drives the sealing component to work, which can effectively seal the leak. The auxiliary component can further improve the sealing effect, preventing the leak from remaining in a state of disrepair before repair, thus avoiding water waste. Compared with the prior art, the present invention, through the cooperation of the detection mechanism and the sealing mechanism, avoids the problem that existing long-distance pipeline leakage detection devices cannot temporarily seal the leak when a pipeline leak is detected, which easily leads to water waste.

[0030] In one embodiment of the present invention, please refer to Figures 1-8 The detection cavity 23 is provided on each side of the sealing cavity 14; The detection assembly includes a detection piece 11 fixedly installed in the detection hole 13.

The bottom of the detection piece 11 is provided with an absorbent cloth 15 for connecting the two sets of wires 16. The detection plate 11 is also provided with an electric heating wire 17 for drying the absorbent cloth 15, and multiple sets of the electric heating wire 17 are provided on both sides of the absorbent cloth 15.

[0031] In this embodiment, both the bottom of the detection pad 11 and the absorbent cloth 15 are concave arc-shaped structures, and the curvature of this structure is the same as the curvature of the semi-circular hole wall inside the housing 1, which facilitates the movement of the absorbent cloth 15 against the surface of the pipe. In use, the wires 16 in each set of detection pads 11 are connected in parallel to the same warning circuit or warning system. The warning circuit or warning system adopts existing publicly available technology. When the absorbent cloth 15 slides past the leak, the leaked water wets the absorbent cloth 15, making the absorbent cloth 15 conductive, thereby connecting the two sets of wires 16. This connects the power supply, thereby activating the warning circuit or system and enabling the warning function. The electric heating wire 17 dries the wetted absorbent cloth 15, facilitating reuse. Both ends of the sealing cavity 14 are equipped with detection cavities 23, allowing leakage detection during forward or backward movement. A water immersion sensor can be installed within the detection cavity 23 to promptly detect water entering it, providing auxiliary detection. A drain hole 9 is also provided at the bottom of the detection cavity 23 to drain water. More preferably, a ceramic heating element can replace the electric heating wire 17. The ceramic heating element is connected to the power supply, and when energized, it dries the absorbent cloth 15.

Both the upper and lower ends of the sealing box 6 are provided with connecting holes 10, and the end of the sealing box 6 away from the sealing cavity 14 has an opening. And an elastic sealing strip 7, which is fixedly installed inside the opening of the sealing box 6, forming a sealed cavity structure between the sealing box 6 and the elastic sealing strip 7; The connectivity component includes: A connecting block 19, one end of which is fixedly installed in one of the connecting holes 10, and the other end of which is provided with a sealing airbag 21, and the connecting block 19 has an air guiding cavity. Through holes 20, multiple sets of through holes 20 are opened at both ends of the connecting block 19, and the through holes 20 are connected to the air guiding cavity inside the connecting block 19; And an air guide channel 22 is provided on the side wall of the connecting block 19, the air guide channel 22 being used to seal the communication between the airbag 21 and the cavity inside the connecting block 19; The starting component includes an air pump 2 fixedly installed on the housing 1, and the output end of the air pump 2 is connected to one of the sealing boxes 6 through a conduit 12. The auxiliary components include: The telescopic component 4 is fixedly installed on the sealing box 6, and two sets of pressing rollers 18 are symmetrically arranged on the telescopic end of the telescopic component 4; wherein the telescopic component 4 can be an electric telescopic rod. The take-up roller 5 is rotatably installed inside the sealing box 6, and two sets of take-up rollers 5 are symmetrically arranged inside the sealing box 6.

Two sets of the auxiliary components are symmetrically arranged inside the sealing box 6.

[0033] In this embodiment, after the two sets of housings 1 are connected, the connecting block 19 is inserted into the connecting hole 10 of the opposing sealing box 6, so that the two sets of sealing boxes 6 can communicate with each other. When the sealing cavity 14 moves to the leak, the air pump 2 can introduce gas through the conduit 12 into one of the sealing boxes 6. The connecting block 19 can make both sets of sealing boxes 6 filled with gas. After the gas completely fills the cavity between the sealing box 6 and the elastic sealing strip 7, it will exert pressure on the elastic sealing strip 7, so that the elastic sealing strip 7 is in full contact with the pipe surface, realizing the sealing function. After the elastic sealing strip 7 is completely pressed onto the pipe surface, the air pump 2 continues to work, so that some gas can enter the sealing airbag 21 through the air guide channel 22, so that... The sealing airbag 21 inflates, and the inflated sealing airbag 21 will fully fill the connection between the connecting block 19 and the connecting hole 10, thereby improving the sealing performance of the connection between the two sets of sealing boxes 6. Finally, the auxiliary components start to work. Specifically, the telescopic component 4 will drive the pressing roller 18 to press onto the elastic sealing strip 7, and at the same time, the motor will drive the winding roller 5 to rotate, using the winding roller 5 to wind up the elastic pressing strip 8, so that the elastic pressing strip 8 is completely pressed onto the elastic sealing strip 7. Through the cooperative arrangement of the two sets of elastic pressing strips 8, one side of the elastic sealing strip 7 can be fully pressed. Through the mutual cooperation of the auxiliary components in the two sets of sealing boxes 6, the elastic sealing strip 7 can be pressed in the circumferential direction, further improving the sealing effect.
