[0038] Preferably, Figure 2 , Figure 3 , Figure 6As shown, the top end of the vibration probe 15 passes through the rubber waterproof pad 9 and is fixed on the lower surface of the supporting steel plate 8. A conductive vibration guide needle 7 is provided on the upper surface of the supporting steel plate 8, and the top end of the conductive vibration guide needle 7 is connected to the vibration sensor 5; the vibration sensor 5 and the vibration probe 15 are connected via the conductive vibration guide needle 7 and the supporting steel plate 8.

[0039] Preferably, Figure 2 , Figure 5 , Figure 6 As shown, screw threads are provided on the outer circumferential surfaces of the bottom ends of the first water-proof and vibration-isolating belt 11 and the second water-proof and vibration-isolating belt 10; a rotating handle 801 is provided on the upper surface of the supporting steel plate 8, and the supporting steel plate 8, the first water-proof and vibration-isolating belt 11, the second water-proof and vibration-isolating belt 10, and the vibration probe 15 are driven to rotate by the rotating handle 801, and the first water-proof and vibration-isolating belt 11, the second water-proof and vibration-isolating belt 10, and the vibration probe 15 are drilled into the pipe wall 101 of the water supply pipe 1.

[0040] In the present embodiment, the first water-proof vibration-isolating belt 11 and the second water-proof vibration-isolating belt 10 are both made of metal, and the first water-proof vibration-isolating belt 11, the second water-proof vibration-isolating belt 10, the conductive vibration-guide needle 7, the vibration probe 15, the support steel plate 8, and the rotating handle 801 are an integrated connector, that is, the top of the first water-proof vibration-isolating belt 11 and the top of the second water-proof vibration-isolating belt 10 are fixed on the lower surface of the support steel plate 8, and the rubber water-proof pad 9 is bonded to the lower surface of the support steel plate 8, and will not interfere with the vibration probe 15, the first water-proof vibration-isolating belt 11, and the second water-proof vibration-isolating belt 10.

[0041] Furthermore, after the first water-proof and vibration-isolating belt 11, the second water-proof and vibration-isolating belt 10, and the vibration probe 15 are passed through the platform through hole 301, since the length of the vibration probe 15 is greater than the length of the first water-proof and vibration-isolating belt 11, and the length of the first water-proof and vibration-isolating belt 11 is greater than the length of the second water-proof and vibration-isolating belt 10, the bottom end of the vibration probe 15 first contacts the outer peripheral surface of the water supply pipe 1. As the rotating handle 801 rotates downward, the vibration probe 15 first drills into the pipe wall 101 of the water supply pipe 1, and then the first water-proof and vibration-isolating belt 11 drills into the pipe wall 101 of the water supply pipe 1 through the screw thread at the bottom end, and finally the second water-proof and vibration-isolating belt 10 drills into the pipe wall 101 of the water supply pipe 1 through the screw thread at the bottom end.

[0042] Preferably, Figure 2-Figure 6As shown, it also includes a water body vibration monitoring component, which has the same structure as the water supply pipe vibration monitoring component; the length of the vibration probe in the water body vibration monitoring component is greater than the vibration probe 15 in the water supply pipe vibration monitoring component; the vibration probe in the water body vibration monitoring component is immersed in the water of the water supply pipe 1.

[0043] In this embodiment, the structure of the water body vibration monitoring component is the same as that of the water supply pipe vibration monitoring component. The only difference is that the length of the vibration probe in the water body vibration monitoring component is greater than the vibration probe 15 in the water supply pipe vibration monitoring component. Therefore, for the convenience of distinction, the vibration probe in the water body vibration monitoring component is now defined as the water body monitoring vibration probe 12. The first water-proof vibration isolation belt 11, the second water-proof vibration isolation belt 10, the conductive vibration guide needle 7, the support steel plate 8, the rotating handle 801, and the vibration sensor 5 in the water body vibration monitoring component all use the same names of parts in the water supply pipe vibration monitoring component. The water body monitoring vibration probe 12 is immersed in the water body of the water supply pipe 1, and is mainly used to monitor the noise generated by the flow of water in the water supply pipe 1 in real time. The diameter of the hole drilled by the water body monitoring vibration probe 12 and the vibration probe 15 on the pipe wall 101 of the water supply pipe 1 is 1 mm, which is very small to prevent the water supply pipe 1 from collapsing at this point due to water pressure. The radius of the water body monitoring vibration probe 12 is greater than the radius of the vibration probe 15 and is a metal structure. In order to be waterproof, the radius of the water body monitoring vibration probe 12 is less than 0.3 mm.

[0044] Preferably, Figure 2 , Figure 5 , Figure 6 As shown, a circuit board 13 is also provided in the sealed chamber, and capacitive conductive probes 6 are provided between the circuit board 13 and the supporting steel plate 8 in the water supply pipe vibration monitoring assembly and between the supporting steel plates 8 in the water body vibration monitoring assembly; the vibration probe 15, the water body monitoring vibration probe 12, the water body in the water supply pipe 1, and the circuit board 13 constitute a closed circuit for monitoring the voltage parameters and capacitance parameters between the vibration probe 15 and the water body vibration probe 15.

[0045] In this embodiment, the vibration probe 15, the water monitoring vibration probe 12, the water in the water supply pipe 1, and the circuit board 13 constitute a closed circuit for monitoring the vibration probe 15 drilling into the pipe wall 101 of the water supply pipe 1, whether there is water leakage when the water monitoring vibration probe 12 drills into the pipe wall 101 of the water supply pipe 1, and whether the water monitoring vibration probe 12 is immersed in the water.

[0046] When the water body monitoring vibration probe 12 is not immersed in the water body, the vibration probe 15, the water body monitoring vibration probe 12, the water body in the water supply pipe 1, and the circuit board 13 form a closed circuit that is disconnected, and the voltage between the two is equal to the open circuit voltage; when the water body monitoring vibration probe 12 is immersed in the water body, the vibration probe 15, the water body monitoring vibration probe 12, the water body in the water supply pipe 1, and the circuit board 13 form a closed circuit that is connected, and the voltage between the two is equal to the water body partial pressure, so whether the water body monitoring vibration probe 12 is immersed in the water body can be judged by whether there is a voltage between the vibration probe 15 and the water body monitoring vibration probe 12.

[0047] When judging whether there is a water leakage at the pipe wall 101 of the water supply pipe 1, when there is no water leakage at the pipe wall 101, there is only a single capacitance medium of the resin pipe between the vibration probe 15 and the water body monitoring vibration probe 12, so the capacitance value between the two is the minimum value of the system; when there is a water leakage at the pipe wall 101, there are capacitance media such as water, the first water-proof vibration isolation belt 11, and the second water-proof vibration isolation belt 10 between the vibration probe 15 and the water body monitoring vibration probe 12, so the capacitance value between the two is increased compared with when there is no water seepage. In addition, when the water seepage reaches the first water-proof vibration isolation belt 11 but does not reach the second water-proof vibration isolation belt 10, the proportion of liquid between the vibration probe 15 and the water body monitoring vibration probe 12 increases, and the capacitance value further increases; when the water seepage exceeds the second water-proof vibration isolation belt 10, the proportion of liquid between the vibration probe 15 and the water body monitoring vibration probe 12 increases further, and the capacitance value further increases. In this way, the position reached by the water seepage can be qualitatively judged by the different capacitance value measurement results.

[0048] Preferably, Figure 2-Figure 6 As shown, a battery 14 is also provided in the sealed chamber, and the battery 14 supplies power to the circuit board 13, the water supply pipe vibration monitoring component, and the water body vibration monitoring component.

[0049] Preferably, Figure 1 As shown, the installation assembly 2 includes a plurality of cable ties 201 , which are fixedly connected to the base platform 3 , and are wrapped around the outer circumference of the water supply pipe 1 ; a rubber fixing pad 203 is also provided between the water supply pipe 1 and the base platform 3 .

[0050] In this embodiment, there are two cable ties 201, and the material of the cable ties 201 is steel. The head and tail of the cable ties 201 are connected by a cable tie fastening ring 202. Accordingly, the cable tie 201 can be directly connected to the base platform 3 as a whole, or an arc-shaped connecting hole can be opened in the base platform 3, and the cable tie 201 passes through the arc-shaped connecting hole. The purpose of setting the rubber fixing pad 203 in this application is to ensure the stability of the base platform 3 when installed on the water supply pipe 1, and the first water-proof vibration isolation belt 11, the second water-proof vibration isolation belt 10, the water body monitoring vibration probe 12, and the vibration probe 15 all pass through the rubber fixing pad 203.

[0051] To achieve the above purpose or other purposes, the present invention discloses a method for using a multi-phase resin water supply pipeline vibration monitoring device, using the multi-phase resin water supply pipeline vibration monitoring device, the steps are as follows:

Press down and rotate the handle 801 to pass the first water-proof and vibration-isolating belt 11, the second water-proof and vibration-isolating belt 10, and the water monitoring vibration probe 12 through the platform through hole 301 and press them onto the outer circumferential surface of the water supply pipe 1. The water monitoring vibration probe 12 first drills into the pipe wall 101 of the water supply pipe 1 and is located at the downstream position of the water supply pipe 1 on the rubber water-proof pad 9 to complete the basic positioning.

[0058] Then rotate and press the rotating handle 801, the first water-proof and vibration-isolating belt 11 drills into the pipe wall 101 of the water supply pipe 1, and then the second water-proof and vibration-isolating belt 10 drills into the pipe wall 101 of the water supply pipe 1, until the bottom end of the water body monitoring vibration probe 12 just contacts with the surface of the water body in the water supply pipe 1. At this time, the water body monitoring vibration probe 12 contacts the water body, and the capacitance value suddenly increases significantly. After that, continue to rotate and press the rotating handle 801 to make the water body monitoring vibration probe 12 penetrate into the water. At this time, the lower surface of the rubber water-proof pad 9 on the lower side of the water body vibration monitoring component just contacts with the upper surface of the base platform 3 and is bonded by glue; when the first water-proof and vibration-isolating belt 11 and the second water-proof and vibration-isolating belt 10 rotate and drill into the pipe wall 101 of the water supply pipe 1, the filled elastic waterproof material is squeezed and overflows outward, thereby filling between the second water-proof and vibration-isolating belt 10 and the platform through hole 301, ensuring the airtightness of the platform through hole 301, and disconnecting the measurement signal line on the capacitive conductive probe 6;

[0059] A4: The operator installs the water supply pipe vibration monitoring assembly into another platform through hole 301.

[0060] A4.1: First, fill the elastic waterproof material between the first water-proof and vibration-proof belt 11 and the second water-proof and vibration-proof belt 10, and between the first water-proof and vibration-proof belt 11 and the vibration probe 15;

[0061] A4.2: Ground one end of the capacitive sensor on the circuit board 13 and connect the other end to the capacitive conductive probe 6 to monitor the corresponding capacitance of the vibration probe 15 at any time. Press down and rotate the handle 801 to pass the first water-proof and vibration-isolating belt 11, the second water-proof and vibration-isolating belt 10, and the vibration probe 15 through the platform through hole 301 and press them onto the outer circumferential surface of the water supply pipe 1. The vibration probe 15 first drills into the pipe wall 101 of the water supply pipe 1 and is located upstream of the water supply pipe 1 on the rubber water-proof pad 9 to complete the basic positioning.

[0062] Then rotate and press the rotating handle 801, the first water-proof and vibration-isolating belt 11 drills into the pipe wall 101 of the water supply pipe 1, and then the second water-proof and vibration-isolating belt 10 drills into the pipe wall 101 of the water supply pipe 1, until the bottom end of the vibration probe 15 just contacts the surface of the water body in the water supply pipe 1. At this time, the vibration probe 15 contacts the water body, and the capacitance value suddenly increases significantly. After that, slightly rotate and lift the rotating handle 801 to make the vibration probe 15 return to the pipe wall 101. At this time, the lower surface of the rubber water-proof pad 9 on the lower side of the water supply pipe vibration monitoring component just contacts the upper surface of the base platform 3 and is bonded by glue; when the first water-proof and vibration-isolating belt 11 and the second water-proof and vibration-isolating belt 10 are rotated and drilled into the pipe wall 101 of the water supply pipe 1, the filled elastic waterproof material is squeezed and overflows outward, thereby filling between the second water-proof and vibration-isolating belt 10 and the platform through hole 301, ensuring the airtightness of the platform through hole 301, and disconnecting the measurement signal line on the capacitive conductive probe 6;

[0063] A5: Further verify the status of the water monitoring vibration probe 12 and the vibration probe 15; the battery 14 supplies power to the circuit board 13. When the water monitoring vibration probe 12 is not immersed in the water body, the vibration probe 15, the water monitoring vibration probe 12, the water in the water supply pipe 1, and the circuit board 13 are in an open circuit state, and the voltage between the two is the open circuit voltage of the power supply; when the water monitoring vibration probe 12 is immersed in the water body, the vibration probe 15, the water monitoring vibration probe 12, the water in the water supply pipe 1, and the circuit board 13 form a closed circuit connection, and the voltage between the two is the corresponding partial pressure of the water body. In this way, whether there is a voltage between the vibration probe 15 and the water monitoring vibration probe 12 can be used to determine whether the water monitoring vibration probe 12 is immersed in the water body. That is, it is determined whether the water body vibration monitoring component and the water supply pipe vibration monitoring component in steps A3 and A4 are installed in place;

[0064] A6: After the water body vibration monitoring assembly and the water supply pipe vibration monitoring assembly are installed, the waterproof housing 4 is fixed on the base platform 3 to form a sealed chamber between the waterproof housing 4 and the base platform 3;

[0065] A7: Daily vibration monitoring; When the water body vibration monitoring component and the water supply pipe vibration monitoring component are installed, the battery 14 always supplies power to the water body vibration monitoring component and the water supply pipe vibration monitoring component. Since the water body monitoring vibration probe 12 is always immersed in the water body, that is, the water body monitoring vibration probe 12 can monitor the vibration and water body noise caused by the flow of the water body, and then transmit it to the vibration sensor 5 through the conductive vibration guide needle 7, and then the vibration sensor 5 collects the parameters of the vibration and water body noise caused by the flow of the water body, and the vibration parameter amplitude and frequency of the water body itself are T1; since the vibration probe 15 is always located inside the pipe wall 101, that is, the vibration probe 15 can monitor the vibration caused by the water supply pipe 1, and then transmit it to the vibration sensor 5 through the conductive vibration guide needle 7, and then the vibration sensor 5 collects the vibration parameters of the water supply pipe 1, and the vibration parameter amplitude and frequency of the water supply pipe 1 itself are T2;

[0066] When the water supply pipe 1 vibrates, the vibration probe 15 detects that the water supply pipe 1 vibrates, and the vibration parameter size of the water supply pipe 1 is T2; then the two vibration sensors 5 transmit T1 and T2 to the circuit board 13 respectively, and then the circuit board 13 performs information processing through the information processing transmission system, and the actual vibration parameter size T of the water supply pipe 1 is T2-T1; the actual vibration parameter size T of the water supply pipe 1 is compared with the expected vibration parameter of the water supply pipe 1. When the difference between the actual vibration parameter size T of the water supply pipe 1 and the set vibration parameter is outside the error range, it indicates that the vibration of the water supply pipe 1 is abnormal and there may be a pipe burst; when the difference between the actual vibration parameter size T of the water supply pipe 1 and the set vibration parameter is within the error range, it indicates that the vibration of the water supply pipe 1 is not caused by a pipe burst; dual-probe monitoring can more accurately capture the daily vibration law of the pipeline and reduce measurement deviation;

[0067] A8: Pipe burst vibration monitoring; when the water supply pipe 1 vibrates after a pipe burst, taking PVC pipe as an example, the time difference △t between the vibration peak value of the water body vibration monitoring component and the water supply pipe vibration monitoring component, according to the solid sound transmission speed of the pipe material is v1, the corresponding propagation time is t1; the water body sound transmission speed is v2, the corresponding propagation time is t1+△t, and v1>v2, combined with the relationship between the propagation speed of sound and the propagation distance v1*t1=v2*t1+v2*△t, the propagation time of the sound signal of the pipe burst of the water supply pipe 1 in the pipe wall 101 is calculated as: t1=v2*△t / (v1-v2), and the possible occurrence distance is L=v1*v2*△t / (v1-v2).

[0068] A8: Daily water leakage monitoring of water supply pipe 1; when the water body vibration monitoring component and the water supply pipe vibration monitoring component are installed, the battery 14 always supplies power to the water body vibration monitoring component and the water supply pipe vibration monitoring component. When there is no water leakage at the pipe wall 101, there is only a single capacitance medium of the resin pipe between the vibration probe 15 and the water body monitoring vibration probe 12, so the capacitance value between the two is the minimum value of the system; when there is water leakage at the pipe wall 101, there are capacitance media such as water, the first water-proof vibration isolation belt 11, and the second water-proof vibration isolation belt 10 between the vibration probe 15 and the water body monitoring vibration probe 12, so the capacitance value between the two is increased compared to when there is no water seepage. In addition, when the amount of water seepage reaches the first water-proof vibration isolation belt 11 but does not reach the second water-proof vibration isolation belt 10, the proportion of liquid between the vibration probe 15 and the water body monitoring vibration probe 12 increases, and the capacitance value further increases; when the amount of water seepage exceeds the second water-proof vibration isolation belt 10, the proportion of liquid between the vibration probe 15 and the water body monitoring vibration probe 12 further increases, and the capacitance value further increases. In this way, the position reached by the water seepage can be qualitatively determined by the different capacitance measurement results. The determination structure is transmitted to the information processing transmission system through the circuit board 13 for information processing;

[0069] A9: Installing a plurality of multi-phase resin water supply pipeline vibration monitoring devices at equal intervals on the water supply pipe 1 according to steps A1-A6 can realize real-time monitoring of the water supply pipe 1.

[0070] The multi-phase resin water supply pipeline vibration monitoring device and use method of the present invention directly detects the vibration of the water supply pipe 1 by inserting a vibration probe 15 into the pipe wall 101 of the water supply pipe 1, and simultaneously sets a water supply pipe vibration monitoring component and a water body vibration monitoring component, wherein the water supply pipe vibration monitoring component is used to monitor the vibration of the water supply pipe 1 in real time, and the water body vibration monitoring component is used to monitor the vibration of the water body in real time. When the water supply pipe 1 vibrates, the difference in vibration parameters between the water body vibration monitoring component and the water supply pipe vibration monitoring component is the actual parameter of the vibration of the water supply pipe 1, and then the actual parameter of the vibration of the water supply pipe 1 is compared with the set vibration value, so as to determine whether the vibration is caused by the burst of the water supply pipe 1, that is, to determine whether the water supply pipe 1 has burst, which is more accurate than the monitoring result of only monitoring the pipe wall 101 of the water supply pipe 1 in the prior art.

[0071] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
