Abstract
The present invention is an acoustic leak sensor that can detect the sound source of the leak by detecting the sound generated by the leak when there is an internal pressure, such as leaks or water pressure inside the building, such as an apartment building to provide. The acoustic sensor includes a sound receiving disk for receiving the sound from the leak in the housing; A piezo buzzer equipped with a piezoelectric element for converting the sound into an electrical signal; A disk for fixing the piezo buzzer; A sound absorbing sponge that fixes the disk to the housing and blocks the signal received by the piezo buzzer from being transmitted to the housing; Cushion rubber for preventing a signal received at the surface of the inspection object from entering the housing; And an internal connection line and a connector.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to acoustic sensors for leak detection used for buildings such as apartments and leak detection of waterworks.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to an acoustic sensor for leak detection used for leak detection of buildings or waterworks in apartments, etc. The sensor mainly finds a leak location on a wall surface of an apartment, or tracks the origin of leaks where the tap water leaks. It is used as a way to. If there is a real leak, you can often hear it without the use of equipment, so if you use acoustic sensors and leak detectors, their performance is noticeably less valuable.
Accordingly, the present invention has been devised to solve the above-described problem, and provides an acoustic sensor capable of efficiently detecting an acoustic signal from a leak source.
The leak detection acoustic leak sensor for solving the above object has the following configuration. That is, the sensor, the sound receiving disk for receiving the sound from the leak in the housing; A piezo buzzer equipped with a piezoelectric element for converting the sound into an electrical signal; A disk for fixing the piezo buzzer; A sound absorbing sponge that fixes the disk to the housing and blocks the signal received by the piezo buzzer from being transmitted to the housing; Cushion rubber for preventing a signal received at the surface of the inspection object from entering the housing; And an internal connection line and a connector. The leak detection acoustic sensor is connected to a main body, that is, an amplifier. The main body is to display the measurement results measured by the acoustic sensor for leak detection of the present invention.
As a result, by using the acoustic sensor according to the present invention, it is possible to make an acoustic sensor that is easy to use and excellent in reception sensitivity. It is understood that various modifications and variations can be made by those skilled in the art without departing from the appended claims.
1 is a cross-sectional view of an acoustic sensor according to the present invention.
An embodiment of the acoustic sensor for leak detection according to the present invention will be described with reference to the drawings.
1, reference numeral 1 denotes a housing, 2 a piezo buzzer, 3 an acoustic receiving disk, 4 a fixing screw, 5 a cushion rubber, 6 a spacing ring, 7 a fixing holder, and 8 a sound absorption. Sponge, 9 is the connecting line, 10 is the connector, 11 is the lid.
In the acoustic leak sensor for leak detection of the present invention, the acoustic sensor includes: a sound receiving disk (3) for receiving sound generated from the leak in the housing (1); A piezo buzzer (2) equipped with a piezoelectric element for converting the sound into an electrical signal; Disk for fixing the piezo buzzer (2), sound-absorbing sponge (8) for fixing the disk to the housing (1) and blocks the signal received by the piezo buzzer (2) from being transmitted to the housing (1) ; A cushion rubber 5 for preventing a signal received at the surface of the test object from entering the housing 1; And an internal connection line 9 and a connector 10.
The leak detection acoustic sensor is connected to a main body, that is, an amplifier. The main body is to display the measurement results measured by the acoustic sensor for leak detection of the present invention.
