Description

Technical Field

[0001] The present application relates to the technical field of municipal sewage pipe equipment, and in particular to a method of finding a municipal sewage pipe system by using underwater sound transmission. Background Art

[0002] At present, underground pipelines are an important part of urban infrastructure and the basis for cities to perform various functions. Municipal public pipelines such as water supply, rainwater, sewage, natural gas, heat, electricity, and communications required for production and life are all set up underground. Since underground pipelines involve many functional departments and are huge in scale, with the development of urbanization, the scale of domestic cities is getting larger and larger, and underground pipelines involve hidden projects, which are becoming more and more complex. In the maintenance process of urban sewage pipe networks, how to accurately find the whereabouts of sewage pipes in use and the correspondence between sewage pipes and sewage wells has become a problem that needs to be solved urgently.

[0003] In the diving field of related technology, a special underwater buzzer for diving has been designed (US5951205A). This buzzer is used with a gas tank and can emit a sound of 125-130dB underwater. It can be transmitted 1000 meters underwater and the direction of sewage pipes in underground pipelines can be found by underwater sound transmission.

[0004] With respect to the above-mentioned related technologies, the inventor believes that: currently, in order to determine the destination of the sewage pipe and the corresponding relationship between the sewage pipe and the sewage well, it is necessary to drain the sewage in the pipe and send workers to the pipe to determine the destination. This method has the following disadvantages:

[0005] The sewage in the pipe needs to be drained out, and the pipe needs to lose its normal sewage discharge function before the direction of the sewage pipe and the corresponding relationship between the sewage pipe and the sewage well can be determined;

[0006] Even if the pipes are drained, some of the pipes are narrow and workers may not be able to enter. In addition, the underground pipe environment is harsh or even dangerous, posing a threat to the safety of workers. Utility Model Content

[0007] The purpose of the present application is to provide a method for finding a municipal sewage pipe system by using underwater sound transmission, so as to solve the problem that in order to determine the direction of the sewage pipe and the corresponding relationship between the sewage pipe and the sewage well, the sewage in the pipe needs to be pumped out and workers need to be dispatched to the pipe to determine the direction. This method has the following disadvantages: 1. The sewage in the pipe needs to be pumped out, and the pipe needs to lose its normal sewage discharge function before the direction of the sewage pipe and the corresponding relationship between the sewage pipe and the sewage well can be determined; 2. Even if the pipe is pumped out, the space in some parts of the pipe is narrow and workers may not be able to enter. In addition, the underground pipe environment is harsh or even dangerous, posing a threat to the safety of workers.

[0008] The present application provides a method for finding a municipal sewage pipe system by underwater sound transmission, which adopts the following technical solution:

[0009] A system for finding a municipal sewage pipe using underwater sound transmission includes a first surface sewage well and a second surface sewage well. An underground sewage pipe is connected between the bottoms of the first surface sewage well and the second surface sewage well. An underwater buzzer is placed underwater in the first surface sewage well, and the underwater buzzer is connected to a gas tank. An underwater pickup is placed underwater in the second surface sewage well, and a computer device connected to the underwater pickup is arranged on one side of the second surface sewage well.

[0010] Furthermore, the top wellheads of the first surface sewage well and the second surface sewage well are both covered with soundproof top covers.

[0011] Furthermore, the soundproof top cover includes a top cover frame and soundproof cotton arranged on the top cover frame.

[0012] Furthermore, the outer sides of the top wellheads of the first surface sewage well and the second surface sewage well are both provided with wellhead frames, and the wellhead frames cooperate with the top cover frames.

[0013] Furthermore, a frame groove is opened on the top of the wellhead frame, and the side of the top cover frame facing away from the sound insulation cotton is inserted into the frame groove.

[0014] Furthermore, a sealing strip is arranged in the groove wall of the frame groove, and the sealing strip abuts against the top cover frame.

[0015] Furthermore, the underwater microphone is electrically connected to an input terminal of the computer device via an electric wire.

[0016] Furthermore, a wire hole is opened on one side of the top cover frame, and the wire passes through the wire hole and penetrates the top cover frame.

[0017] Furthermore, a sealing rubber ring matching with the electric wire is arranged on the hole wall of the electric wire hole.

[0018] Compared with the prior art, the beneficial effect of the present application is that by setting up a structure in which an underwater buzzer, a gas tank, an underwater microphone, and computer equipment cooperate with each other, underwater sound transmission is used to find the pipe, and the effect can be exerted even if the pipe is tortuous. The unique sound of the underwater buzzer is transmitted underwater. If the underwater buzzer and the underwater microphone are connected by water, the underwater microphone can receive a clear signal.

[0019] At the same time, the system is not only easy to carry, but also has strong anti-interference ability and low chance of false detection. It uses sound insulation cotton to cover the wellhead to isolate the interference of sound propagation in the air medium on the underwater pickup reception. Moreover, it does not require workers to enter the underground pipeline, thus avoiding threats to the workers' safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following is combined with Figure 1-2 This application is described in further detail.

[0024] The present application embodiment discloses a method for finding a municipal sewage pipe system by underwater sound transmission, referring to Figure 1 In this embodiment, the system includes a first surface sewage well 1, a second surface sewage well 2, an underground sewage pipe 3, an underwater buzzer 4, a gas tank 5, an underwater pickup 6 and a computer device 7. The underground sewage pipe 3 is connected between the bottoms of the first surface sewage well 1 and the second surface sewage well 2; the underwater buzzer 4 is placed underwater in the first surface sewage well 1, and the underwater buzzer 4 can emit a unique sound; the gas tank 5 is connected to the underwater buzzer 4, and the underwater buzzer 4 is floated underwater in the first surface sewage well 1 by the arrangement of the gas tank 5.

[0025] At the same time, the underwater microphone 6 is placed underwater in the second ground sewage well 2, and the unique sound of the underwater buzzer 4 can be heard; the computer device 7 is placed on the external side of the second ground sewage well 2, and the underwater microphone 6 is electrically connected to the input end of the computer device 7 through the wire 12, so that the underwater microphone 6 receives a clear signal and displays a clear, unique peak of the underwater buzzer 4 in the computer device 7, so that the first ground sewage well 1 and the second ground sewage well 2 are judged whether they are connected according to the strength of the displayed peak signal. If the first ground sewage well 1 and the second ground sewage well 2 are determined to be connected by a pipeline, the direction of the underground sewage pipeline 3 can be found.

[0026] Therefore, by setting up a structure in which the underwater buzzer 4, the gas tank 5, the underwater microphone 6, and the computer equipment 7 cooperate with each other, the underwater sound transmission is used to find the pipe, and the effect can be exerted even if the pipe is tortuous. The unique sound of the underwater buzzer 4 is transmitted underwater. If the underwater buzzer 4 is connected to the underwater microphone 6 by water, the underwater microphone 6 can receive a clear signal.

[0027] At the same time, the system of the present application is not only easy to carry and widely used, but also does not require workers to enter underground pipelines, thereby avoiding threats to the safety of workers.

[0028] In addition, refer to Figure 1 and Figure 2 In this embodiment, the top wellheads of the first surface sewage well 1 and the second surface sewage well 2 are covered with a soundproof top cover 8, and the soundproof top cover 8 includes a top cover frame and soundproof cotton; wherein the four peripheral sides of the soundproof cotton are fixedly installed at the upper edge of the top cover frame.

[0029] By respectively covering the top wellheads of the first surface sewage well 1 and the second surface sewage well 2 with a soundproof top cover 8 composed of a top cover frame and soundproof cotton installed together, the interference of sound propagating in the air medium on the underwater microphone 6 can be isolated, and it has the advantages of strong anti-interference ability and low false search probability.

[0030] In addition, refer to Figure 1 and Figure 2 In order to facilitate the stable installation of the two sound insulation covers 8 at the top wellheads of the first ground sewage well 1 and the second ground sewage well 2, respectively, in this embodiment, wellhead frames 9 are provided on the outer sides of the top wellheads of the first ground sewage well 1 and the second ground sewage well 2, and the wellhead frames 9 cooperate with the top cover frames of the sound insulation covers 8.

[0031] A frame groove 10 is provided on the top of the wellhead frame 9, and the side of the top cover frame facing away from the sound insulation cotton cooperates with the frame groove 10, so that the edge of the top cover frame is inserted into the frame groove 10, so that the wellhead frame 9 covers the top cover frame, which makes it easy to firmly position the two sound insulation top covers 8 at the top wellheads of the first ground sewage well 1 and the second ground sewage well 2.

[0032] Preferably, a sealing strip 11 is installed in the groove wall of the frame groove 10, and the sealing strip 11 abuts against the top cover frame, thereby achieving an effective sealing effect, thereby further isolating the interference of sound propagation in the air medium on the reception of the underwater microphone 6.

[0033] Secondly, refer to Figure 1 and Figure 2 In the present embodiment, a wire hole 13 is provided on one side of the top cover frame, and the wire 12 connecting the underwater microphone 6 and the computer device 7 passes through the wire hole 13 and passes through the top cover frame. By providing the wire hole 13, it is possible to prevent the wire 12 from being clamped and compressed and thus damaged.

[0034] At the same time, a sealing rubber ring 14 is installed on the hole wall of the wire hole 13, and the sealing rubber ring 14 cooperates with the wire 12 so that the wire 12 passes through the sealing rubber ring 14. Therefore, by providing the sealing rubber ring 14, not only can the wire 12 be effectively positioned and installed, but also a certain sealing effect can be achieved.

[0035] The implementation principle of the present application embodiment using underwater sound transmission to find the municipal sewage pipeline system is as follows:

[0036] Start the underwater buzzer 4. If the underwater microphone 6 receives and displays a clear, unique wave crest of the underwater buzzer 4 on the computer device 7, and the signal is strong, it proves that the two wells are connected. If the displayed wave crest signal is weak or the interference is extremely large, the two wells are not connected. At the same time, the underwater microphone 6 cannot receive the unique wave crest of the underwater buzzer 4, and the two wells are not connected.

[0037] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
