Description

A sensor attaching seet and a method of detachment sensor to a pipe joint.}

The present invention relates to a leak detection sensor for applying to a system for detecting a breakage and a leak in a buried pipe, and more particularly, a leak detection sensor installed on a connection portion of a pipe to quickly measure even a slight leak.

9A is a perspective view showing the appearance of a leak detection sensor as shown in FIG. 9A.

The leak detection sensor 20 is a rectangular parallelepiped, which can be separated up and down, and a passage 22 through which two lines of copper wire enter and exit is installed on both sides of the rectangular enclosure, and water enters and exits the upper surface of the upper enclosure 23. A plurality of holes 24 are provided at regular intervals.

One end of the copper wire extending to the passage 22 is a female connector 25 and the other end is a male connector 26.

9B is a cross-sectional view taken along line A-A' in FIG. 2.

The lower conductive material 31 and the upper conductive material 32 are mounted on the lower layer inside the enclosure, and the spiral wire 33 is located inside the lower conductive material. An impermeable cloth 34 is placed on the upper portion of the upper conductive inducing material 32.

The lower conduction-inducing material 31 is made of celloroid foam (FOAME) or cellulose using natural pulp, and the upper conduction-inducing material is melanin foam (FOAME).

In addition, the lower conduction-inducing material 31 is not electrolytically treated, and the upper conduction-inducing material 32 is electrolytically treated.

This is to pre-electrolyte the internal conduction-inducing material to strengthen the energizing atmosphere inside the sensor (increasing electrolytic power), but in the case of the lower conduction-inducing material, it contains a bare wire. The lower conduction-inducing material is not treated with electrolyte.

At this time, NaCl or NaOH may be used as the electrolyte.

In addition, the impermeable cloth 34 is made of micropore or ProporeFabric material, and the impermeable cloth 34 does not pass water under atmospheric pressure, but when the pressure becomes higher than atmospheric pressure, water is introduced into the enclosure. It will serve to pass through.

However, the prior art is not only a complicated configuration, but also has 4 terminals, so that signal attenuation cannot be avoided.

In addition, since it is disposed on the joint and is stepped outward to the joint, it is configured in a more protruding form, so an external enclosure is required to withstand earth pressure.

Therefore, the amount of work increases and there is much room for reliability problems.

If there is pressure in the form of a short circuit or water leakage, the leak detection sensor cannot be broken.

The sensor of the prior art is configured such that in the event of a leak, the sheet attached to the leak detection sensor is first separated, then water flows into the hole formed in the sensor enclosure, and then the water expanding rubber or spring inside the sensor is operated to short circuit the sensor. Therefore, the manufacturing process was complicated, the leak detection time was long, and the cost was increased because the upper and lower sensors had to be assembled and supplied in the factory.

In the prior art detection sensor, when a leak occurs, the butyl sheet attached to the outside of the sensor is separated first, and water is introduced into the hole formed in the enclosure to expand the water expansion rubber so that water leakage can be detected. It takes a long time and has been limited to leaking liquid components.

Korea Patent Office Registration No. 10-1074337 (2011.10.17) Korea Patent Office Patent Publication No. 10-2006-0004741 (2006.01.16) Republic of Korea Patent Office Registration No. 10-1807739 (December 12, 2017)

The first problem to be solved is that the upper sensor and the lower sensor of the detachable sensor are configured to be separated directly, and when an event occurs and the sensor protection device swells, the sensor needs to be activated immediately.

The second task is to solve the problem of cost savings because the upper and lower sensors are produced integrally with the sensing sheet and not assembled in separate factories.

The third problem is to solve the problem that can be applied to the piping network that transports gas, such as gas, because the detachable sensor of the present invention is not necessarily a sensor that operates only when water is introduced into the inside.

The fourth problem is that the detachable sensor of the present invention is manufactured by directly combining the sensors separated into upper and lower ends on both ends of the sensing sheet, thereby reducing production costs and fundamentally solving the problem of quality problems caused by assembly errors.

The fifth task is that the existing sensor must use 4 connection jacks to connect the sensor and the sensor line to the seat in the field, but the detachable sensor of the present invention is produced by directly connecting the sensor to the sheet where the sensor line is inserted. Therefore, it has solved the problem of reducing the material cost and labor cost.

The sixth task is that the existing crimping sensor strips part of the sensing wire to cause a short circuit in the event of a leak, so if the sensor is not completely sealed, there is a risk of the sensing wire shorting due to corrosion due to long-term use. There is a possibility that signal attenuation may occur according to the present invention, but the detachable sensor housing of the present invention is configured to be completely sealed and the sensor wire is not exposed to solve the problem of fundamentally preventing short circuit and signal attenuation caused by corrosion. .

The detachable sensor of the present invention is configured such that the upper sensor and the lower sensor are directly separated, and an event occurs, so that the sensor is activated immediately when the sensor protection device swells.

The second effect is that the upper and lower sensors are produced in one piece with the sensing sheet, so they are not assembled in separate factories, thereby reducing costs.

The third effect is that the detachable sensor of the present invention is a sensor that can be applied to a pipe network that transports gas, such as gas, because it is not a sensor that works only when water flows in.

As a fourth effect, since the detachable sensor of the present invention is manufactured by directly combining the sensors separated into upper and lower ends on both ends of the sensing sheet, it is possible to reduce production costs and fundamentally solve quality problems caused by assembly errors.

The lower sensor 200 comprises a rubber insert 215 so that the connection terminal protrusion 116 of the upper sensor 100 is inserted into the lower sensor connection terminal 210 of the lower sensor 200. It is desirable to have a configuration that does not cause a short circuit even when moisture flows into the sensor 10.

It will be described below with reference to Figures 6a and 6b.

The sensing line sheet 300 applies butyl to the sheet 320 and attaches the sensing line 310 thereto.

The sensing line 310 may be configured such that two sensing lines are arranged inside one circular line, such as a household wire.

The same is true of two separate sensing lines.

It is preferable to have a configuration for attaching a butyl-attached rubber plate 330 to which butyl is attached to the upper part of the sensing line 310.

This is to protect the sensing line.

It is necessary to work to prevent the detection line from being disconnected during construction considering that it is attached to the surface of the pipe and buried in soil and stone corresponding to a considerable weight.

Therefore, the butyl-attached rubber plate 330 to which butyl is attached is appropriate.

Here, after attaching the butyl-attached rubber plate 330, after attaching the butyl release paper 340 to the top of the butyl-attached rubber plate 330, storage and movement, and butyl are attached to attach the sensing line sheet to the surface of the buried pipe. The removed release paper 340 is removed and attached to the surface of the tube.

It will be described below with reference to Figures 7a to 8c.

The method for attaching the sensor line sensor to the joint of the tube is as follows.

And attaching the first lower sensor of the sensor line sheet attaching sensor 1000 around the joint of the tube.

First, the lower sensor is attached to the joint of the tube, and then the upper sensor is combined.

In order to protect the detachable sensor 10 that combines the upper sensor and the first lower sensor, the step of configuring the sensor protection device 400 to be wrapped around the detachable sensor 10.

The word meaning of the detachable sensor 10 means that the upper sensor and the lower sensor are combined.

There is a method of attaching the detachable sensor 10 to the pipe joint by having a step of attaching a protective cover having high durability to the upper portion of the sensor protection device 400.

The protective cover is a buried pipe to protect the detachable sensor when buried by solid stones buried in the buried pipe and the like.

After the step of configuring the sensor protection device 400 to wrap, it is preferable to have a step of wrapping a flexible tape on the side surface of the sensor protection device 400.

The sensor protection device has a V-shape on both sides and is designed to seal the water or moisture from reaching the detachable sensor from the outside of the tube, that is, from the outside.

It is configured to seal the sensor protection device 400 regardless of the presence or absence of a step.

The sensor protection device 400 constitutes a watertight portion 410 and a step watertight portion 420 on both sides.

And it is composed of a space support portion 435 having a space portion 430 in the central portion.

The detachable sensor has a volume, and it is preferable to cut out the space support part 435 from the sensor protection device 400 so that uneven portions are not generated unnecessarily due to the detachable sensor 10.

7B and 7C are views showing that the space support portion 435 is removed and the detachable sensor 10 is inserted into a corresponding portion.

The left and right directions correspond to the circumferential direction of the tube, and the direction of the sensing line indicates the length direction of the tube.

Here, the step of wrapping the side portion of the sensor protection device 400; thereafter further comprising the step of configuring the sensor protection cover 600 on the upper portion of the sensor protection device 400, part of the upper portion of the detachable sensor (10) It is preferable to configure the upper portion of the sensor protection device 400 surrounding the.

The step watertight portion 420 covers the portion where the step joint 30 is located in the sensor protection device 400.

Even if there is a step portion, it is advantageous in that it is configured to be watertight simply by the step watertight portion 420.

The sensor protection device 400 is a flexible material, and in the present invention, a rubber material is acceptable.

7D shows an example of application of the sensor protection device 400 as having a joint between pipes having no step.

7E is a view showing that the detachable sensor 10 is attached to the joint of the tube and the sensor protection device 400 is wrapped to protect the detachable sensor.

7F covers the elastic protective tape that is the first tape 510 in FIG. 7E, but attaches the side portion of the sensor protection device 400, so that the watertight part 410 and the step watertight part 420 of the sensor protection device 400 are attached. Is configured to be more watertight.

Therefore, when leaking from the joint, it is prevented from leaking to the outside of the detachable sensor 10, and liquid such as water from outside the joint is prevented from entering the inside of the detachable sensor 10, so that it exhibits performance. The detachable sensor 10 is prevented from malfunctioning by the water.

In addition, the liquid is prevented from leaking to the outside of the detachable sensor 10 inside the pipe joint to quickly determine whether or not it leaks.
