Description

Technical Field

[0001] The utility model belongs to the technical field of detection devices, and in particular relates to a rapid detection device for water leakage in a water supply network. Background Art

[0002] A rapid water supply network leak detection device is a device used to identify and locate leaks in water supply pipes. This type of device uses physical phenomena such as sound, vibration, or pressure changes to quickly and accurately detect leaks in the pipes. The most common method for existing rapid water supply network leak detection devices is to use a handheld detection device to investigate leaks in the water supply network. This device primarily uses sound wave detection to determine the approximate location of the leak, thereby defining a specific area for subsequent, precise investigations. The advantages of this type of device are its flexibility and convenience. It detects the location of the leak by detecting the strength of underground sound waves transmitted from the ground. Its handheld design facilitates daily portability, leading to its widespread use. However, its drawbacks are also obvious. Since this type of device relies on underground sound waves for detection, external noise can interfere with its use. This noise can mix with the sound waves generated by the leak, interfering with the device's ability to detect the leak. Therefore, a new structure has been proposed to address this issue. Utility Model Content

[0004] The utility model is realized by the following technical solutions: a rapid detection device for water leakage in a water supply network, comprising: a handle, a sound receiving disk and sound insulation cotton, a display disk is provided at the center of the handle, a connecting rod is welded at the center of the bottom of the display disk, and a sound wave receiving mechanism is provided at the bottom of the connecting rod;

[0010] As a preferred embodiment, the sound receiving disk is a trumpet-shaped structure with a diameter gradually shrinking from bottom to top, and the top of the sound receiving disk extends upward to the inside of the sound wave structure mechanism. The connection between the top of the sound receiving disk and the bottom of the sound wave receiving mechanism is connected by sealant. The trumpet-shaped structure can make the sound receiving disk more focused and increase the frequency of sound waves transmitted from underground. The side of the sound receiving disk is in close contact with the ground, which has a certain noise reduction effect.

[0012] As a preferred embodiment, the area enclosed by the side of the sound wave converter away from the center of the circle and the side of the sound insulation cotton close to the center of the circle forms a sound insulation cavity, and nitrogen is injected into the sound insulation cavity.

By arranging sound insulation cotton and a sound insulation cavity, nitrogen is injected into the sound insulation cavity through two groups of air filling ports, and nitrogen has a sound insulation effect, which assists the sound insulation cotton in sound insulation. The sound insulation cotton is glued to the inside of the sound wave receiving mechanism, which can absorb and soundproof the noise coming from the side, bottom and top of the sound wave receiving mechanism, and prevent the external noise from being too loud and mixed with the sound wave signal, resulting in unstable sound wave signal reception and distortion of the sound wave signal, thereby preventing noise from interfering with water leakage detection.

[0023] See also Figures 1 to 4 A rapid detection device for water leakage in a water supply network comprises a handle 100, a sound receiving disk 220 and sound insulation cotton 240. A display disk 110 is provided at the center of the handle 100. A connecting rod 120 is welded at the center of the bottom of the display disk 110. A sound wave receiving mechanism 200 is provided at the bottom of the connecting rod 120.

[0024] Four groups of support columns 210 are equidistantly arranged in an annular area away from the center of the bottom of the sound wave receiving mechanism 200. A sound receiving disk 220 is installed at the center of the bottom of the sound wave receiving mechanism 200. The horizontal height of the bottom edge of the sound receiving disk 220 is the same as the horizontal height of the bottom edge of the four groups of support columns 210.

[0025] Two groups of air inlets 201 are provided on the left and right sides of the top of the sound wave receiving mechanism 200. Sound insulation cotton 240 is glued to the inner side of the sound wave receiving mechanism 200. A sound insulation cavity 250 is provided on the side of the sound insulation cotton 240 close to the center of the circle.

[0026] The display panel 110 is connected and fixed to the inner side of the handle 100 via two sets of reinforcing ribs. The display panel 110 has a built-in signal receiving module, a signal display module, a control module and a power supply module.

[0027] A signal amplifier 130 is provided above the outer side of the connecting rod 120, a telescopic cylinder 140 is provided below the signal amplifier 130, an electric push rod is installed inside the telescopic cylinder 140, and a telescopic rod is provided below the telescopic cylinder 140;

[0028] The top of the telescopic rod is connected and fixed to the bottom of the electric push rod, and the bottom of the telescopic rod is fixed to the center of the top of the sound wave receiving mechanism 200. The signal amplifier 130 is connected to the display panel 110 through wireless signal one, and the electric push rod is connected to the display panel 110 through wireless signal two. The electric push rod installed inside the telescopic tube 140 can drive the telescopic rod to extend and retract, thereby extending or shortening the overall length of the device, making it easier to cope with ground environments with different height conditions and increasing the convenience of using the device.

[0029] The sound receiving disk 220 is a trumpet-shaped structure with a diameter that gradually shrinks from bottom to top. The top of the sound receiving disk 220 extends upward to the inside of the sound wave structure mechanism. The connection between the top of the sound receiving disk 220 and the bottom of the sound wave receiving mechanism 200 is connected by sealant. The trumpet-shaped structure can make the sound receiving disk 220 more concentrated and increase the frequency of sound waves coming from underground. The side of the sound receiving disk 220 is in close contact with the ground, which has a certain noise reduction effect. At the same time, the main function of the sound receiving disk 220 is to collect and amplify sound waves.

[0030] A sound wave converter 231 is provided on the top of the sound receiving disk 220 . The sound wave converter 231 is located above the interior of the sound wave receiving mechanism 200 . The sound wave converter 231 is connected to the sound wave receiver 230 via a wire.

[0031] The area enclosed by the side of the sound wave converter 231 away from the center of the circle and the side of the sound insulation cotton 240 close to the center of the circle forms a sound insulation cavity 250. Nitrogen is injected into the sound insulation cavity 250. Nitrogen is an inert gas and has a high density, so it can have a certain sound insulation effect and assist the sound insulation cotton 240 in sound insulation.

[0032] The radius length of the top opening of the sound insulation cotton 240 matches the radius length of the sound wave converter 231, the radius length of the bottom opening of the sound insulation cotton 240 matches the radius length of the bottom of the sound receiving disk 220, the inner side of the top opening of the sound insulation cotton 240 is glued and fixed to the outer side of the sound wave converter 231, the inner side of the bottom opening of the sound insulation cotton 240 is glued and fixed to the outer side of the sound receiving disk 220, and the outer side surface of the sound insulation cotton 240 is glued and fixed to the inner wall of the sound wave receiving mechanism 200. Therefore, the sound insulation cotton 240 can absorb and reduce noise coming from the top, bottom and sides of the sound wave receiving mechanism 200.

[0033] Example 1: Please refer to Figures 1 to 3 In actual use, the staff first enters the ground of the water supply network area with the handheld device, then holds the left and right sides of the handle 100 with both hands, places the bottom of the sound wave receiving mechanism 200 flat on the ground, and keeps the connecting rod 120 vertical to the ground. At this time, the bottoms of the four groups of support columns 210 are all in contact with the ground, and because the bottom edge of the sound receiving disk 220 is at the same height as the bottom of the support column 210, the bottom of the sound receiving disk 220 is in contact with the ground and is in close contact with it. If a slightly rugged ground is encountered, it is only necessary to ensure that the bottom of the sound receiving disk 220 is in contact with the ground, and it is not necessary for the bottom of the sound receiving disk 220 to be in theoretical close contact with the ground. The side surface of the bottom of the sound receiving disk 220 only plays an auxiliary noise reduction effect, and its main function is to amplify the frequency of underground vibration. At this time, the vibration waves of the underground water flow will be transmitted through the ground and received by the sound receiving disk 220. The horn-shaped structure of the sound receiving disk 220 can collect and amplify these sound waves, and then transmit them upward to the sound wave receiver 230;

[0034] The sound wave receiver 230 receives the sound wave vibration and transmits it to the sound wave converter 231. The sound wave converter 231 converts the vibration wave into an electrical signal that can be recognized by the display panel 110, and then continues to transmit it upward to the signal amplifier 130 for secondary amplification, and finally transmits it to the display panel 110. The sound wave information is displayed on the display panel 110. The display panel 110 is provided with water leakage sound wave information. After comparing it with the collected sound wave information, it can be known whether the underground water supply network here is leaking (the above sound wave collection, forwarding, amplification and comparison are all existing technologies, and the sound waves used are The receiver 230, sound wave converter 231, signal amplifier 130 and display panel 110 are all existing technologies and will not be described in detail here. At the same time, if a relatively low ground is encountered, the electric push rod installed inside the telescopic cylinder 140 can be controlled by the display panel 110 to drive the telescopic rod to extend, thereby extending the entire device to facilitate the contact between the sound receiving panel 220 and the ground. The final effect is that the bottom side of the sound receiving panel 220 can play an auxiliary noise reduction effect. At the same time, the sound receiving panel 220 can gather the sound wave vibrations from the underground and transmit them upward, reducing the interference of external noise.

[0035] Example 2: Please refer to Figure 3 and Figure 4 When the sound wave receiving mechanism 200 is collecting underground sound waves, the sound insulation cotton 240 glued to the side of the sound wave receiving mechanism 200 can absorb and weaken the external noise. The top of the sound insulation cotton 240 is glued to the upper part of the sound wave receiving mechanism 200, the inner side of the opening at the top center of the sound insulation cotton 240 is glued to the outer side of the sound wave converter 231, and the inner side of the bottom opening of the sound insulation cotton 240 is glued to the outer side of the part of the sound receiving disk 220 extending into the interior of the sound wave receiving mechanism 200, thereby absorbing and reducing the noise coming from the top and sides of the sound wave receiving mechanism 200, greatly reducing the influence of external noise on the water sound waves. Sufficient nitrogen is injected into the sound insulation cavity 250 through two sets of air filling ports 201. The density of nitrogen is slightly smaller than that of air (under standard conditions, the density of nitrogen is 1.25g / L, and the density of air is about 1.29g / L). When sound propagates in a medium, the density of the medium is a factor that affects the speed of sound and sound attenuation. Generally speaking, a medium with a smaller density has a relatively slower sound propagation speed, and the sound is more easily scattered and attenuated during the propagation process, which can have a certain noise reduction effect. In combination with the sound insulation cotton 240, the external noise can be greatly reduced to prevent the external noise from interfering with the water leakage detection work, which greatly reduces the difficulty of regional inspection before maintenance.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
