[0002] During home renovation, it's necessary to inspect the installed water supply and drainage pipes, such as by filling them with water and conducting pressure tests. A manual pressure testing pump is typically used for this purpose. The process involves selecting a section of pipe, closing the corresponding valve, threading the output of the manual pressure testing pump to the pipe opening, injecting test fluid into the pipe, and observing the pressure gauge to determine the pressure value. Finally, the system is checked for leaks.
[0003] In the existing technology, manual pressure testing pumps have a simple structure and a single testing function. When performing other testing items, they also need to be disassembled and drained, which is inconvenient to operate. Fully automatic testing devices are expensive to manufacture and have high operating costs. Summary of the Invention

The pipe fixing supports are equipped with vibration sensors. The lower end of the water supply and drainage pipe is connected to an inlet solenoid valve, a water filling device, and a pressure testing device. The water filling device supplies clean water at a certain pressure and flow rate into the installed water supply and drainage pipes to simulate actual operating conditions and assist in inspection. The pressure testing device pressurizes and replenishes pressure in the water supply and drainage pipes to maintain the test pressure. The higher end of the water supply and drainage pipe is connected to a detection valve assembly and a recovery device. The detection valve assembly includes an integrated multi-parameter sensor and a drain solenoid valve. The integrated multi-parameter sensor detects the pressure and flow rate of the water in the water supply and drainage pipes. The drain solenoid valve closes the water supply and drainage pipes for pressure testing, or quickly opens and closes the drain solenoid valve to simulate water hammer, working in conjunction with the vibration sensor to detect the installation quality and sealing performance of the water supply and drainage pipes. The recovery device recovers or assists in cleaning the test water in the water supply and drainage pipes.
[0006] Preferably, the irrigation device includes an inlet flow meter, a water storage tank, and an inlet pump. A water intake pipe is provided between the inlet of the inlet pump and the water storage tank, and an irrigation pipe is connected to the outlet of the inlet pump. An inlet solenoid valve is installed on the irrigation pipe, and one end of the irrigation pipe is connected to a water supply and drainage pipe through a reducing joint. The inlet flow meter is installed on the irrigation pipe.
[0007] Preferably, the pressure testing device includes a water tank, a pressure testing pump, a water collection block, and a pressure gauge. The inlet pipe of the pressure testing pump extends into the water tank, and the outlet pipe of the pressure testing pump is connected to the water collection block. The water collection block is connected to the water filling pipe through a high-pressure hose. The water collection block includes a check valve, a shut-off valve, a safety valve, a drain valve, and a switch. The pressure gauge is installed on the water collection block. The water collection block serves as the control hub of the pressure testing pump, responsible for collecting the high-pressure clean water output by the pump and transporting it to the water supply and drainage pipeline to achieve the purpose of pressure testing.
[0008] Preferably, the integrated multi-parameter sensor includes a flow sensor and a pressure sensor, and the integrated multi-parameter sensor is located near the drain end of the water supply and drainage pipe; the recycling device adopts a recycling tank, the water supply and drainage pipe is connected to the recycling tank through a drain end solenoid valve, the top of the recycling tank is provided with a first air pipe, and the bottom of the recycling tank is provided with a drain outlet.
[0009] Preferably, the recycling device uses a recycling pipe, the water supply and drainage pipe is connected to the recycling pipe through a drain end solenoid valve, the recycling pipe is equipped with a second air pipe and a recycling control valve, the recycling control valve is connected to the upper part of the water tank; the water inlet pump is connected to the water tank through a water intake pipe, and a filter device is provided inside the water tank.
[0010] Preferably, the intelligent detection computer controls the opening and closing of the inlet solenoid valve and the outlet solenoid valve, as well as the operating parameters of the inlet pump and the pressure testing device; the intelligent detection computer receives data collected by the vibration sensor, the inlet flow meter, the pressure gauge, and the integrated multi-parameter sensor via wired or wireless means.
[0011] A smart detection method for water supply and drainage engineering construction, wherein the detection steps specifically include: S1. After the water supply and drainage pipelines are installed and fixed with the pipeline fixing brackets, connect the relevant equipment of the intelligent detection system to the water supply and drainage pipelines. S2. When the inlet solenoid valve and the outlet solenoid valve are opened, the water supply device is supplied with water from the lower end of the water supply and drainage pipe, and the air in the water supply and drainage pipe is discharged from the higher end. During this process, the inlet flow meter and the integrated multi-parameter sensor detect the inlet and outlet flow of the water supply and drainage pipe and determine whether the water supply and drainage pipe is blocked. After filling with water, the inlet solenoid valve and the outlet solenoid valve are closed, immersing the water supply and drainage pipes. S3. The pressure test pump draws clean water from the water tank and pumps it into the water filling pipe through the high-pressure hose to pressurize the water supply and drainage pipes. The pressure is slowly increased to the test pressure and stabilized for 30 minutes. During this period, if the pressure drops, water is injected to replenish the pressure, but it must not exceed the test pressure. Check the pipe joints, fittings and other parts for leaks or damage. If any abnormality is found, the pressure test must be stopped, the cause must be identified and repaired, and the pressure test must be repeated. S4. Stop water injection and pressurization, stabilize for 15 minutes. If the pressure drop does not exceed the allowable pressure drop value after 15 minutes, reduce the test pressure to the working pressure and maintain constant pressure for 30 minutes. Perform a visual inspection. If there is no leakage, the water pressure test is qualified. S5. Open the inlet solenoid valve and the outlet solenoid valve. The inlet pump supplies clean water with a certain pressure and flow rate into the water supply and drainage pipes. The outlet solenoid valve closes quickly, and a pressure pulse is generated in the water supply and drainage pipes instantly to simulate the water hammer effect. Check the pipe surface for abnormal deformation, cracks, or other phenomena to ensure the integrity of the pipe. At the same time, pressure sensors and vibration sensors collect pressure changes and vibration frequencies at the corresponding pipe supports in real time. The data acquisition system and analysis software are used to process and analyze the collected data to assess the pipe's pressure-bearing capacity, installation quality, sealing performance, and potential defects, providing comprehensive protection for the safe operation of the pipe. S6. Close the inlet solenoid valve and the outlet solenoid valve again, and pressurize the test pump with water. Maintain the test pressure for 15 minutes. If the pressure drop does not exceed the allowable pressure drop value and there is no leakage, it means that the pipeline installation is qualified. S7. Open the inlet solenoid valve and the outlet solenoid valve to quickly recover the residual clean water in the water supply and drainage pipes by injecting air into the first or second air pipe.
[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses an intelligent detection computer to control the operation of the inlet solenoid valve, the outlet solenoid valve, the inlet pump, and the pressure testing device to simulate various working conditions of water supply and drainage pipelines or to conduct pressure tests.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0016] Reference Figure 1-4 A smart detection system for water supply and drainage engineering construction includes a water supply and drainage pipeline 1, a pipeline fixing support 11 and a smart detection computer, wherein a vibration sensor is provided on the pipeline fixing support 11. The lower end of the water supply and drainage pipe 1 is connected to an inlet solenoid valve 41, a water filling device and a pressure testing device 5. Water is supplied from the lower end of the water supply and drainage pipe 1, which can quickly fill the water supply and drainage pipe 1 and expel the air in the water supply and drainage pipe 1. Example 1: The irrigation device is used to supply clean water with a certain pressure and flow rate into the installed water supply and drainage pipe 1 to simulate the actual working conditions of the water supply and drainage pipe 1 and assist in the testing. The irrigation device includes an inlet flow meter 2, a water storage tank 3 and an inlet pump 4. The water storage tank 3 and the inlet pump 4 can be integrated and assembled on a mobile trailer for easy handling and movement. A water intake pipe 43 is provided between the inlet of the inlet pump 4 and the water storage tank 3, or the water intake pipe 43 can be directly connected to the tap water supply pipe. The outlet of the inlet pump 4 is connected to an irrigation pipe 42. The inlet solenoid valve 41 is installed on the water filling pipe 42 to control the opening and closing of the water inlet, or to close the water inlet of the water supply and drainage pipe 1, which facilitates subsequent pressure testing. One end of the water filling pipe 42 is connected to the water supply and drainage pipe 1 through the reducer 12. The reducer 12 can be adapted to various water supply and drainage pipes 1, improving the equipment adaptability. The inlet flow meter 2 is installed on the water filling pipe 42 to record the inlet flow. The pressure testing device 5 is used to pressurize and replenish the pressure of the water supply and drainage pipeline 1 to maintain the test pressure. The pressure testing device 5 includes a water tank 51, a pressure testing pump 52, a water collection block 53, and a pressure gauge 54. The inlet pipe of the pressure testing pump 52 extends into the water tank 51 to draw clean water from the water tank 51. The outlet pipe of the pressure testing pump 52 is connected to the water collection block 53. The water collection block 53 is connected to the water filling pipe 42 through a high-pressure hose. The water collection block 53 includes a check valve, a stop valve, a safety valve, a drain valve, and a switch. The pressure gauge 54 is installed on the water collection block 53. The water collection block 53 serves as the control hub of the pressure testing pump 52 and is responsible for collecting the high-pressure clean water output by the pump and transporting it to the water supply and drainage pipeline 1 to achieve the purpose of pressure testing. The higher end of the water supply and drainage pipe 1 is connected to a detection valve assembly 7 and a recovery device. The detection valve assembly 7 includes an integrated multi-parameter sensor 71 and a drain end solenoid valve 72. The integrated multi-parameter sensor 71 includes a flow sensor and a pressure sensor. The integrated multi-parameter sensor 71 is located near the drain end of the water supply and drainage pipe 1. The integrated multi-parameter sensor 71 is used to detect the pressure and flow rate of the water in the water supply and drainage pipe 1. The drain end solenoid valve 72 is used to close one end of the water supply and drainage pipe 1 for pressure testing, or to quickly open and close the drain end solenoid valve 72 during the water supply process of the water pump 4 to simulate the water hammer phenomenon, and to cooperate with the vibration sensor to detect the installation quality and sealing performance of the water supply and drainage pipe 1. The intelligent detection computer controls the opening and closing of the inlet solenoid valve 41 and the outlet solenoid valve 72, as well as the working parameters of the inlet pump 4 and the pressure testing device 5. The working parameters are mainly the speed and start / stop of the inlet pump 4, and the pressure and flow of the pressure testing pump 52 of the pressure testing device 5. The intelligent detection computer receives data collected by the vibration sensor, water flow meter 2, pressure gauge 54 and integrated multi-parameter sensor 71 via wired or wireless means. For long distances, the detection personnel can use mobile phones or other terminal devices to connect to the Internet and transmit sensor data. The recycling device is used to recycle or assist in cleaning the test water in the water supply and drainage pipe 1. When the two ends of the water supply and drainage pipe 1 are far apart, the recycling device uses a recycling tank 6. The water supply and drainage pipe 1 is connected to the recycling tank 6 through the drain end solenoid valve 72. The top of the recycling tank 6 is equipped with a first air pipe 61, which is connected to an air valve and an air pump for venting or injecting air into the recycling tank 6 to quickly discharge the test water in the water supply and drainage pipe 1. The bottom of the recycling tank 6 is equipped with a drain outlet 62, which is equipped with a valve to facilitate the discharge of water from the recycling tank 6, which is then collected in the water storage tank 3. When the two ends of the water supply and drainage pipe 1 are close together, in Example 2, the recycling device uses a recycling pipe 8. The water supply and drainage pipe 1 is connected to the recycling pipe 8 through the drainage end solenoid valve 72. The recycling pipe 8 is equipped with a second air pipe 81 and a recycling control valve 82. The recycling control valve 82 is connected to the upper part of the water tank 51. The water inlet pump 4 is directly connected to the water tank 51 through the water intake pipe 43, which directly eliminates the need for the water storage tank 3 and the recycling tank 6, reducing equipment costs. The inside of the water tank 51 is equipped with a filter device to filter the test water and prevent impurities from clogging the water inlet pump 4 and the test pressure pump 52.
[0017] Intelligent detection methods for water supply and drainage engineering construction include: S1. After the water supply and drainage pipe 1 is installed and fixed by the pipe fixing bracket 11, connect the relevant equipment of the intelligent detection system to the water supply and drainage pipe 1. S2. The inlet solenoid valve 41 and the outlet solenoid valve 72 are opened, and the water supply device is supplied with water from the lower end of the water supply and drainage pipe 1. The air in the water supply and drainage pipe 1 is discharged from the higher end. During this process, the inlet flow meter 2 and the integrated multi-parameter sensor 71 detect the inlet and outlet flow of the water supply and drainage pipe 1 and determine whether the water supply and drainage pipe 1 is blocked. After filling with water, the inlet solenoid valve 41 and the outlet solenoid valve 72 are closed, and the water supply and drainage pipe 1 is fully soaked under a pressure not greater than the working pressure. S3. The test pressure pump 52 draws clean water from the water tank 51 and pumps it into the water filling pipe 42 through the high pressure hose to pressurize the water supply and drainage pipe 1. The test pressure is usually 1.5 times the working pressure and not less than 0.6MPa. Slowly increase the pressure to the test pressure and stabilize it for 30 minutes. A pressure drop of ≤0.05MPa is acceptable. If the pressure drops during this period, inject water to replenish the pressure, but it must not exceed the test pressure. Check the pipe joints, fittings, etc. for leaks or damage. If any abnormality is found, stop the pressure test, find out the cause, repair it, and then retest the pressure. S4. Stop water injection and pressurization, stabilize for 15 minutes. If the pressure drop does not exceed the allowable pressure drop value after 15 minutes, reduce the test pressure to the working pressure and maintain constant pressure for 30 minutes. Perform a visual inspection. If there is no leakage, the water pressure test is qualified. S5. Open the inlet solenoid valve 41 and the drain solenoid valve 72. The inlet pump 4 supplies clean water with a certain pressure and flow rate into the water supply and drainage pipe 1. The drain solenoid valve 72 closes quickly. The closing time of the drain solenoid valve 72 must be much less than the time required for the pressure wave to travel back and forth once in the water supply and drainage pipe 1, so as to generate significant water hammer pressure. A pressure pulse is generated instantaneously in the water supply and drainage pipe 1 to simulate the water hammer effect. Check the pipe surface for abnormal deformation, cracks, etc. to ensure the integrity of the pipe. At the same time, pressure sensors and vibration sensors collect pressure changes in the water supply and drainage pipe 1 and vibration frequency at the corresponding pipe fixing support 11 in real time. The data acquisition system and analysis software are used to process and analyze the collected data to evaluate the pipe's pressure bearing capacity, installation quality, sealing performance and potential defects, so as to provide comprehensive protection for the safe operation of the pipe. If the vibration is obvious, it means that the pipe fixing support 11 is not installed firmly and needs to be adjusted to ensure that the water supply and drainage pipe 1 is fixed reliably. S6. Close the inlet solenoid valve 41 and the drain solenoid valve 72 again, and pressurize the test pump 52 with water. Maintain the test pressure for 15 minutes. If the pressure drop does not exceed the allowable pressure drop value and there is no leakage, it means that the pipeline installation is qualified. S7. Open the inlet solenoid valve 41 and the drain solenoid valve 72, and inject air into the first air pipe 61 or the second air pipe 81 through the air pump to quickly recover the residual clean water in the water supply and drainage pipe 1.
