Description

Technical Field

[0001] This utility model relates to the field of underground engineering and detection technology, and in particular to a trenchless underground pipeline leak detection device. Background Technology

[0002] Underground pipelines are an important component of urban infrastructure, used to transport resources such as water, gas, natural gas, sewage, electricity, and communications. They are typically buried underground to protect the pipelines from environmental impacts and minimize interference with surface activities. Underground pipeline systems are complex and extensive, including water supply pipelines, drainage pipelines, gas pipelines, power cables, and communication fiber optic cables. The construction and operation of these pipelines are crucial to the normal functioning of a city and the quality of life of its residents. Through scientific planning, construction, and maintenance, underground pipelines can provide efficient and safe services to the city, supporting its sustainable development.

[0003] A search revealed that the document with publication number "CN216555665U" mentions that "this utility model relates to the field of underground pipeline repair technology, and in particular to a trenchless underground pipeline repair auxiliary device, including a base, an auxiliary device body fixedly connected to the upper surface of the base, a heat dissipation vent on the top of the auxiliary device body, support plates fixedly connected to both outer surfaces of the auxiliary device body, a motor cylinder fixedly connected to the lower surface of the support plates, a rotary motor fixedly connected to the top wall of the inner cylinder of the motor cylinder, a rotating shaft fixedly connected to the output end of the rotary motor, and a fixed connection at the lower end of the rotating shaft." The device is equipped with a turntable, with monitoring probes fixedly connected to both sides of the lower surface of the turntable. The auxiliary device body has a monitoring chamber inside, and a shock-absorbing cylinder is fixedly connected to the bottom surface inside the monitoring chamber. When in use, the turntable, monitoring probes, and moving wheels eliminate the need for handheld auxiliary devices, freeing up the workers' hands and improving work efficiency. However, in existing underground pipeline leak detection, the pipeline is often dug up to determine the leakage situation. This is difficult to observe, and the specific location is usually only observed visually after the leakage has become severe and soil deformation has occurred.

[0004] Therefore, we provide a trenchless underground pipeline leak detection device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a trenchless underground pipeline leak detection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a trenchless underground pipeline leak detection device, comprising an underground connecting pipe, a sealing gasket provided on the outside of the underground connecting pipe, a pipe sleeve provided on the outside of the sealing gasket, a water sensing plate provided on the inner wall of the pipe sleeve, and a pressure sensor welded to the upper side of the pipe sleeve.

[0007] Preferably, the sealing gasket and the pipe sleeve are bonded together, the sealing gasket and the pipe sleeve are symmetrically arranged on the left and right sides, and the pipe sleeve and the underground connecting pipe form a sealing structure through the sealing gasket.

[0008] Preferably, the water sensing plate is welded to the sleeve, and the water sensing plate and the sleeve have an arc-shaped structure. The water sensing plate and the air pressure sensor are electrically connected.

[0009] Preferably, a protective steel pipe is welded to the upper side of the pressure sensor, a protective box is welded to the top of the protective steel pipe, a data reactor is arranged inside the protective box, a signal transmitter is arranged on the upper side of the data reactor, and the data reactor is electrically connected to the water sensor board and the pressure sensor.

[0010] Preferably, the signal transmitter and the data reactor are electrically connected.

[0011] Preferably, a power supply battery is provided on the left side of the data reactor, a sealing groove is provided on the front side of the protective box, and a sealing plate is provided on the inner side of the sealing groove.

[0012] Preferably, the sealing plate and the sealing groove are connected by a slot, and the sealing plate and the sealing groove are tightly fitted together.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When needed, the sealing gasket can seal the pipe sleeve and the underground connecting pipe, thus preventing accidental activation due to external water leakage. When leakage occurs at the interface of the underground connecting pipe, the water sensor will detect the water and have an electrical reaction with the water sensor. When the water flow is small, or there is no water in the underground connecting pipe, but a leakage point appears, the air pressure sensor will detect the change in air pressure inside the pipe sleeve, thus identifying the current leakage location.

[0015] 2. The electrical wiring of the air pressure sensor is connected to the data reactor inside the protective steel pipe and protective box for data analysis. This allows staff to easily understand the current data during inspections. In the event of a leak, the data reactor will detect the data change and remotely alert staff via a signal transmitter to conduct a timely investigation, preventing the leak from worsening. The power supply battery can store energy, thus preventing circuit breaks caused by external environmental factors, which could also lead to leaks and prevent the data reactor from detecting data.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 As shown, this utility model provides a technical solution: a trenchless underground pipeline leak detection device, including an underground connecting pipe 1, a sealing gasket 2 on the outside of the underground connecting pipe 1, a pipe sleeve 3 on the outside of the sealing gasket 2, a water sensing plate 4 on the inner wall of the pipe sleeve 3, and a pressure sensor 5 welded to the upper side of the pipe sleeve 3.

[0023] Furthermore, the sealing gasket 2 and the sleeve 3 are bonded together. The sealing gasket 2 and the sleeve 3 are symmetrically arranged on the left and right sides. The sleeve 3 and the underground connecting pipe 1 form a sealing structure through the sealing gasket 2. When needed, the sealing gasket 2 can seal the sleeve 3 and the underground connecting pipe 1, thereby preventing accidental contact due to external moisture leakage.

[0024] Furthermore, the water sensing plate 4 is welded to the pipe sleeve 3, and the water sensing plate 4 and the pipe sleeve 3 have an arc-shaped structure. The water sensing plate 4 and the air pressure sensor 5 are electrically connected. When it is needed, the water sensing plate 4 will sense the water and have an electrical reaction when there is a leak at the interface of the underground connecting pipe 1. When the water flow is small, or there is no water in the underground connecting pipe 1, but there is a leak, the air pressure sensor 5 will sense the change in air pressure in the pipe sleeve 3, thus indicating that there is a leak at the current location.

[0025] Furthermore, a protective steel pipe 6 is welded to the upper side of the pressure sensor 5, and a protective box 7 is welded to the top of the protective steel pipe 6. A data reactor 8 is installed inside the protective box 7, and a signal transmitter 9 is installed on the upper side of the data reactor 8. The data reactor 8 is electrically connected to the water sensor board 4 and the pressure sensor 5. When needed, the wiring of the pressure sensor 5 will perform data analysis through the protective steel pipe 6 and the data reactor 8 inside the protective box 7. This makes it easier for staff to understand the current data when conducting inspections.

[0026] Furthermore, the signal transmitter 9 and the data reactor 8 are electrically connected. When leakage occurs, the data reactor 8 senses the data change and will remotely remind the staff to conduct a timely inspection through the signal transmitter 9 to prevent the leakage from worsening.

[0027] Furthermore, a power supply battery 10 is provided on the left side of the data reactor 8, and a sealing groove 11 is provided on the front side of the protection box 7. A sealing plate 12 is provided on the inner side of the sealing groove 11. When needed, the power supply battery 10 can store energy, thereby avoiding the problem of circuit disconnection caused by external environmental influences, which would also cause leakage and prevent the data reactor 8 from sensing data.

[0028] Furthermore, the sealing plate 12 and the sealing groove 11 are connected by a slot, and the sealing plate 12 and the sealing groove 11 fit tightly together. When needed, the use of the sealing plate 12 and the sealing groove 11 can protect the equipment inside the protective box 7 during the non-staff survey stage.

[0029] Working Principle: A trenchless underground pipeline leak detection device is moved to the working position. In the first step, the underground connecting pipe 1 is buried underground. Then, the connection between the two underground connecting pipes 1 is fitted with a sleeve 3 and sealed with a sealing gasket 2. After installation, soil is buried on the underground connecting pipe 1. During this process, the electrical wiring is connected to the data reactor 8 inside the protective box 7 via a protective steel pipe 6. In the second step, when leakage occurs at the interface of the underground connecting pipe 1, the water sensor 4 senses the water flow, while the air pressure sensor 5 senses the airflow and changes in air pressure. At this time, the data reactor 8 analyzes the current data to determine if it is within a preset critical value. When the critical value is exceeded, a remote alert is sent to the staff via a signal transmitter 9, and the power supply battery 10 provides power. Finally, after the staff arrives at the location, they remove the sealing plate 12 from the sealing groove 11 to analyze and observe the data from the data reactor 8 to determine if maintenance is needed. This completes the operation of the trenchless underground pipeline leak detection device.
