DETAILED DESCRIPTION

[0026] In order to further understand the characteristics, technical means and specific purposes and functions achieved by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0027] Referring to Figures 1-5 The utility model provides: a non - excavation formula water supply pipe network leakage detection device, including water supply pipeline 1 and install on water supply pipeline 1 connecting pipe 2, water supply pipeline 1 is the main part of entire water supply system, is responsible for delivering water source to each water point, connecting pipe 2 still install the pressure detection device 4 for detecting the water pressure in pipe and the flow detection module 5 of detecting water flow, connecting pipe 2 is used to connect and guide water flow to pressure detection device 4 and flow detection module 5, and flow detection module 5 is used for real -time monitoring the water flow in pipe. Water flow data is also crucial for analyzing pipe leakage, because leakage usually leads to abnormal reduction of water flow, and ensures that the detection process does not affect the normal operation of the main water supply pipeline 1. Pressure detection device 4 includes protective shell 41, protective shell 41 also installs pressure sensor for detecting water pressure, the water inlet of the bottom of protective shell 41 is inserted into connecting pipe 2, and electromagnetic valve 42 is also installed on protective shell 41, the water inlet of the bottom of flow detection module 5 is inserted into connecting pipe 2, when pipe is water stop, electromagnetic valve 42 is closed, and water does not enter into protective shell 41, when pipe water flow tends to be stable, electromagnetic valve 42 is opened, and water enters into protective shell 41 to detect the pressure of water in pipe.

[0028] When pipe is water stop, electromagnetic valve 42 can be automatically closed, when pipe restores water supply, water does not enter into pressure detection device 4 in advance, at this time, electromagnetic valve 42 slowly opens, and water slowly enters into pressure detection device 4, which can avoid that instantaneous impact force is too large due to water hammer effect when water supply, leading to damage of pressure detection device 4.

[0029] The pressure detection device 4 further comprises a first sealing plate 44 and a first supporting plate 45, which are tightly connected to the outside of the connecting pipe 2. The first sealing plate 44 is used to block the pores at the joint between the protective shell 41 and the connecting pipe 2, so as to prevent water from leaking from the protective shell 41. The flow detection module 5 is further provided with a second sealing plate 51 and a second supporting plate 52, which are tightly connected to the connecting pipe 2. The second sealing plate 51 is used to seal the joint between the flow detection module 5 and the connecting pipe 2, so as to prevent water from leaking from the flow detection module 5.

[0030] The cross sections of the first sealing plate 44, the first supporting plate 45, the second sealing plate 51 and the second supporting plate 52 are arc-shaped, and they are made of rubber.

[0031] The introduction of the first sealing plate 44, the first supporting plate 45, the second sealing plate 51 and the second supporting plate 52 not only enhances the connection strength and sealing performance between the pressure detection device 4, the flow detection module 5 and the connecting pipe 2, but also improves the stability and reliability of the entire detection device. These design improvements help to ensure that water does not leak out from unintended locations during the detection process, thereby ensuring the accuracy of the detection results and the safety of the device.

[0032] The first sealing plate 44 and the second sealing plate 51 play a sealing role, preventing water from leaking from the pores between the pressure detection device 4 and the connecting pipe 2 or the pores between the flow detection module 5 and the connecting pipe 2.

The storage battery 433 provides power support for the circuit board 43 and all components thereon. The storage battery 433 has the advantages of large capacity, long battery life and easy charging, which can ensure that the device can still work normally in the case of long-term unattended operation.

[0034] When the water supply pipeline 1 supplies water, the electromagnetic valve 42 remains open, and as the water flows into the pressure detection device 4, the pressure sensor begins to work, measuring and recording the water pressure data in the pipeline in real time. The data processing module 431 is responsible for receiving raw data from the pressure sensor and processing and analyzing it. Through the built-in algorithm and logic, the data processing module 431 can identify abnormal changes in water pressure data, such as sudden drops or fluctuations. The data processing module 431 sends the processed data to the background terminal through wireless means, which can be a remote monitoring center, data center, or mobile device, etc. By receiving and analyzing these data, management personnel can monitor the operation of the pipeline in real time and promptly discover and handle potential problems.

[0035] Referring to Figure 4 and Figure 6 As shown, the connecting pipe 2 is also provided with a plurality of clamping devices 3, which are used to fix the first sealing plate 44 and the first support plate 45 on the pressure detection device 4 on the connecting pipe 2, and the second sealing plate 51 and the second support plate 52 on the flow detection module 5 on the connecting pipe 2. The clamping device 3 includes a first clamping piece 31 and a second clamping piece 32, which are movably connected by a shaft. The first clamping piece 31 is movably provided with a fixing bolt 33 by a shaft, which is rotated into a groove on the second clamping piece 32, and a butterfly nut 34 is screwed on the fixing bolt 33. The butterfly nut 34 is used to fix the first clamping piece 31 and the second clamping piece 32. The cross section of the first clamping piece 31 and the second clamping piece 32 is arc-shaped, and they can be spliced into a circular shape.

[0036] During installation, the first sealing plate 44, the first support plate 45, the second sealing plate 51, and the second support plate 52 are placed on the connecting pipe 2, and the first clamping piece 31 and the second clamping piece 32 are clamped on the first sealing plate 44, the first support plate 45, the second sealing plate 51, and the second support plate 52, respectively. Then, rotate the fixing bolt 33 to insert it into the groove on the second clamping piece 32, and tighten the butterfly nut 34 to fix them. As the butterfly nut 34 is tightened, the first clamping piece 31 and the second clamping piece 32 will exert more and more clamping force on the connecting pipe 2, thereby firmly fixing the first sealing plate 44 and the first support plate 45 on the pressure detection device 4, and the second sealing plate 51 and the second support plate 52 on the flow detection module 5 on the connecting pipe 2.
