Description

Leaking pipe and buried pipe detector

The present invention relates to a detector for finding metal pipes buried indoors or outdoors, or to quickly find leaks when leaks are generated from the buried pipes. In particular, since only one main body can detect a leak generator or underground buried pipe, It is very efficient and economical, and it is a leak detector and buried pipe combined detector which improves its use more conveniently by incorporating a multi-button type of frequency filter for eliminating unnecessary noise when leak detection.

The term "leak exploration" began to be used in our country in the early 1980s, and has a long history. In the past, there was no alternative but to find a way to find a leak by digging up the floor by years of experience.

But now, if you pull off high-quality interior materials or dig up and down the asphalt to fix the leak, it's more expensive than repairs, so leak detectors to repair water leaks in less time in less time The system can be used to repair leak points more efficiently and quickly.

The above-mentioned leaks are caused by cracks, and leaks by cracks refer to leaks caused by rainwater, leaks due to rupture of sewer pipes, leaks due to poor waterproof layer, and are not accompanied by pressure.

Another cause is water leakage due to condensation. Condensation refers to the phenomenon of water condensation caused by temperature differences between the inside and outside, such as water droplets forming in cold cold water cups in summer. It occurs in the wrong house and disappears during the day when the temperature rises.

Another cause is leaks caused by pipes, which are leaks generated in buried pipes, causing damage to residents in the lower house, material damages such as interior materials and finishing materials, and inconveniences in residential life. .

The most easy-to-repair and common type of leaks caused by leaks are pipe leaks, which are typically used in the world's most widely used leak detectors. It is no exaggeration to say that 90% of domestic users use this type of leak detector.

Blue food is literally a detection method that tells the earth's exploration sound of leaks through sensors that are in contact with the ground.

Outdoor exploration literally refers to water leakage in the ground of more than 1.2m depth. This is because it is found in the water pressure state, so it is good to have a detector with high amplification and water leakage frequency band in the water pressure state.

Unlike indoors, indoor exploration drains water and finds air pressure in the pipes, so a good detector is a device that finds a leaky frequency band.

Therefore, since it is difficult to apply the outdoor detector indoors, it is generally common to purchase and use a leak detector separately set for outdoor use and indoor use.

In addition, underground buried detectors are also called obstacle detectors, pipe & cable detectors, line detectors, pipeline detectors,

The obstacles buried underground are divided into water supply pipes, sewer pipes, communication cables, electric cables, and gas pipes, and are closely related to our lives, and those that have discontinuities like gold or silver in the ground are underground I do not say.

There are many types of detectors, but the two most commonly used methods are electromagnetic induction and GPR. The information that can be detected by the electromagnetic induction detector is the depth, direction, and location of the metal buried in the ground. In addition, GPR detectors can detect not only metals but also the depth, location, diameter, and geological state of deposits of nonmetals.

The underground buried detectors are widely used in telecommunication construction, underground line-related departments of KEPCO, city gas companies, waterworks in each province, water resources construction, GIS offices, and construction companies.

In particular, since underground underground accidents are frequent, construction and civil engineering companies are in the spotlight as essential equipment, and companies that specialize in leak detection are also widely used.

However, in general, leak detection or detection of underground buried pipes is generally carried out in one construction process.In the case of leaks indoors or outdoors, first, after locating buried pipes, Since leak detection is common, leak detection should be carried simultaneously with a buried pipe detector.

Therefore, there is a need for an operator to unnecessarily carry and transport excessive equipment and equipment, and each of these equipment is very expensive, which adds to the economic burden.

In particular, the leak detection is classified into outdoor use and indoor, respectively, so that the equipment and equipment moved with the worker is very burdensome.

In particular, the leak detector main body 100 as shown in FIG. 5 is provided with a control knob 101 for removing unnecessary noise when listening to the leak, the frequency band is variable according to the rotation of the control knob 101 The amplification of the sound leakage or noise is eliminated, and the adjustment of the frequency by the adjustment knob is not only a very cumbersome operation for the field worker, but also requires a very high level of skill for an inexperienced unskilled man. Even if the adjustment knob is moved or touched during operation, the setting value is easily changed, so it is very necessary to handle it during handling.

In addition, the hearing sensor 102 installed on the indoor and outdoor floors is configured to have an unnecessarily large shape as shown in the drawing, and is not only inconvenient to handle, but also has a problem that effective hearing and sound collection are impossible due to poor adhesion to the ground. .

The present invention was conceived to eliminate the problems as described above, forming a power switch and a switching switch on the control panel of the detector body, respectively, to form a separate multi-stage frequency adjustment button, by combining the headphone insert and the sensor connection port,

Leakage detection as well as buried pipes can be detected with only one main body, which simplifies the equipment and provides convenience of carrying and transporting. It is very convenient because the sound can be optimally listened to, and the sound sensor which is more simplified and has improved adhesion to the ground improves the noise removal efficiency while providing a very convenient leak and buried pipe detector. There is a purpose.

A power switch 3 and a changeover switch 4 are formed on one side operation panel 2 of the detector body 1 in which a known leak detection circuit and a pipe detection circuit are incorporated, and are divided by the changeover switch 4. The detection circuit is switched

The operation panel 2 is provided with a plurality of frequency adjustment buttons 5, 5 'so that the sound frequency band of the leak detection circuit is varied by the adjustment buttons 5, 5',

In the operation panel 2, a headphone insertion port 6, a sensor connection port 7 and a probe socket 8 and 8 'are formed, respectively.

Using this detector body 1,

The changeover switch 4 of the operation panel 2 is switched to the leak detection side, and the sensor connector 7 is coupled with a known connector 10 having a hearing sensor 11 and a short-circuit switch 12, and a headphone insertion hole ( 6) combines a known headphone 13 to be used as a leak detector,

Switch the switch of the operation panel 2 to the pipe detection side, and insert the probes 15 and 15 'having the clips 14 and 14' at the ends into the probe sockets 8 and 8 ', It is to be used as a pipe detector to detect the position of the buried pipe (17) connected to the clip (14, 14 ') using the detector (16).

In addition, the hearing sensor 11 is composed of a sensor unit 18 in close contact with the ground and a close contact pad 19 formed on the outer periphery of the sensor unit 18, but the lower end of the close contact pad 19 By forming the wrinkled portion 20 on the bent to thereby increase the adhesion to the ground to prevent more efficient noise from entering or leaking the sound.

In the figure, reference numeral 21 denotes a volume.

Referring to the action of the present invention leak pipe and buried pipe combined detector by the above configuration in more detail by the accompanying drawings as follows.

As shown in the present invention, the leak and pipe combined detector can detect the leak pipe and the underground buried pipe with only one body.

On the operation panel 2 formed on the front side of the detector main body 1, a power switch 3 for interrupting power is formed, and the power switch 3 applies power to a circuit inside the main body 1, or To act as a short circuit,

The switch 4 on one side is used to switch to a known leak detection circuit or a pipe detection circuit built in the detector main body 1, and only a simple circuit is switched in a state where a common power source is used.

In addition, the operation panel 2 is provided with a frequency adjustment button 5, 5 ', a headphone insertion hole 6, a sensor connector 7, and a probe socket 8, 8' connected to an internal circuit, respectively. The frequency adjustment button (5) (5 ') is to remove the unnecessary noise during the sound leakage, while the role plays a role to amplify the leak, as in the prior art rather than the rotary frequency adjustment method by the dial is set in advance The frequency band value can be selectively used by the adjustment buttons 5 and 5 ', and the frequency band is variably set according to the conditions and conditions of the detection site, so that an appropriate leak sound can be heard.

In addition, the frequency adjustment buttons 5 and 5 'are formed in plural. When two adjustment buttons 5 and 5' are shown in the figure, one button is pressed to filter the low frequency band. If another button is pressed, the mid-frequency band is filtered, but when two buttons are pressed at the same time, the high-frequency band is filtered. It is very convenient to use because it presents a simple and convenient operation.

In addition, it is possible to insert a known headphone 13 into the headphone insertion hole 6 so that it can be used at the time of audible leakage, and the connector 10 can be inserted into the connector 10 withdrawn from the hearing sensor 11. It was made.

In addition, the probe sockets 8 and 8 'are inserted with probes 15 and 15' which are used to detect the pipes. All connections are formed.

Looking at the example of using a leak and pipe detector,

First, the headphone 13 is inserted into the headphone insertion hole 6 of the operation unit 2 of the detector main body 1, and the connector having a hearing sensor 11 and a short-circuit switch 12 is inserted into the sensor connection port 7. 10) in the combined state, when the changeover switch 4 is switched to the leak detection side and the power is applied to the internal circuit according to the operation of the power switch 3, from the buried pipe in the ground from the sound sensor 11 in close contact with the ground. The leakage sound generated is intercepted by the headphone 13, and the volume of the leakage sound intercepted through the volume 21 formed in the operation panel 2 can be adjusted.

At this time, when the hearing sound is unclear or weak, the frequency adjustment buttons 5 and 5 'may be operated to hear the leak sound in a clear and clean state, and the short switch 12 may be touched by hand. Grip is to control the operation of the hearing sensor (11).

Here, the hearing sensor 11 is composed of a sensor unit 18 in close contact with the ground as shown in FIG. 4 and an elastic rubber contact pad 19 formed at its periphery, and of the close contact pad 19. By forming the pleats 20 on the bottom, the contact pads 19 are more elastically in contact with the ground by the pleats 20 described above, and the sound collection of the leakage sound is improved by the improved adhesion to the ground. In addition, since the effect of blocking unnecessary noise generated from the outside is excellent, it is easier to detect the leak generator.

In particular, the close contact pad 19 having the pleats 20 can increase the adhesion to the ground more and can minimize the size of the close contact pad 19 can significantly reduce the size of the hearing sensor 11 Therefore, it is to simplify the handling while providing the convenience of carrying and moving.

In addition, when detecting the pipe embedded in the ground by using the detector main body 1, in the state where the probe 15, 15 'is inserted into the probe socket 8, 8', When the switch 14 is switched to the pipe detecting side while the clip 14, 14 'formed at the end of the probe 15, 15' is grounded at the end of the buried pipe 17, the probe ( 15) The predetermined power is applied to the buried pipe 17 through 15 ',

It is possible to determine the underground buried position of the buried pipe 17 through a separate detector 16 to the electric force of the buried pipe 17 applied.

Therefore, only one main body can perform the function of leak detection or pipe detection by the changeover switch 4 alone, and the piping position of the leak and underground buried pipe as well as indoors and outside can be relatively reduced by more simplified equipment. It can be detected accurately.

Leakage pipe and buried pipe combined detector of the present invention as described above, it is possible to detect leaks as well as buried pipes with only one main body, thus simplifying the equipment and providing convenience of carrying and transporting, and the field operator has a multi-stage frequency adjustment button. It is very convenient because it can be easily operated, even for the unskilled person, so that the sound can be optimally listened to by the non-skilled person. It is a convenient effect.
