Abstract
Description
Technical Field
[0001] The utility model relates to the field of pipe loss detection devices, in particular to a water supply pipeline leakage prevention monitoring device. Background Art
[0002] The water supply pipeline system is an indispensable part of urban infrastructure. With the advancement of urbanization, the water supply demand is increasing day by day. Traditional water supply pipelines are usually buried underground to avoid the direct impact of the external environment. However, in some specific environments and conditions, water supply pipelines need to be laid on the ground. These scenarios usually include temporary water supply facilities, agricultural irrigation systems, industrial parks, remote areas, and water supply systems in some special environments. These above-ground water supply pipelines are more vulnerable to the invasion of the external environment, such as temperature changes, mechanical damage, and ultraviolet radiation. Therefore, higher requirements are put forward for the leakage prevention and alarm systems of the pipelines.
[0003] Most traditional water supply pipeline leakage detection methods rely on manual inspection or simple electronic monitoring devices. However, manual inspection is time-consuming and laborious, and it is difficult to achieve full coverage and real-time monitoring of the pipelines. Leakage problems are often discovered only when serious consequences have occurred. Although electronic monitoring devices can improve the detection efficiency to a certain extent, they usually can only detect the situation after leakage and cannot provide a secondary protection function. In addition, the joints of water supply pipelines, such as flange joints, are extremely vulnerable to leakage due to poor sealing or improper installation. Therefore, the monitoring of these key parts is particularly important.
[0004] In view of the above problems, some new technologies for water supply pipeline leakage detection have been developed in recent years, aiming to improve the detection accuracy and efficiency. Especially at the pipeline joints, through external protection measures and automated monitoring means, leakage signs can be detected earlier, reducing water resource waste and environmental damage. Most of these technologies use electronic components such as sensors and liquid level switches for detection, and at the same time, combined with information technology means, a real-time alarm system is used to remind maintenance personnel to take measures in time. However, there are still deficiencies in the integration of the existing technology in preventing leakage and alarm functions, especially the detection of small-scale leakage and false alarm problems have not been effectively solved. Content of the Utility Model
[0005] To solve the above technical problems, the utility model provides a water supply pipeline leakage prevention monitoring device. By using a housing and a water collecting tank, leakage can be collected, and then a liquid level sensor is used for detection, so that it is more convenient to obtain whether there is leakage, and small-scale leakage can also be detected.
[0006] The technical solution adopted by the utility model to solve its technical problems is: a water supply pipeline leakage prevention monitoring device, including a housing arranged outside the leakage prevention section of the pipeline;
[0007] A water collecting tank is provided at the bottom of the outer shell, and a drain pipe and a liquid level sensor are provided in the water collecting tank.
[0008] In this solution, the outer shell is arranged outside the leak-proof section. If water leakage occurs in the leak-proof section, the water will drain into the outer shell. Since the outer shell is provided with a water collecting tank, the water will first flow into the water collecting tank. The water collecting tank is provided with a drain pipe and a liquid level sensor. When the liquid level sensor detects an increase in the water level, it can send out a signal to the outside so that the staff can be informed. Before the staff arrives, the leaked water can be discharged out through the drain pipe.
[0009] Preferably, it includes a solar cell module and a controller. The solar cell module is fixed to the outer shell. The controller is provided with a wireless transmission module, and the controller is electrically connected to the solar cell module and the liquid level sensor respectively. The solar cell module can supply power to the controller and the liquid level sensor, ensuring the normal operation of electrical components outdoors. When the liquid level sensor detects an increase in the liquid level, it transmits the information to the staff through the wireless transmission module so that the staff can remotely monitor the pipeline status.
[0010] Preferably, the liquid level sensor is a float type liquid level gauge. It has accurate detection and more reliable use.
[0011] Preferably, the water collecting tank is a V-shaped groove with a smaller bottom and a larger top, and the drain pipe and the liquid level sensor are arranged on the side wall of the V-shaped groove. The V-shaped groove can better gather water for the liquid level sensor to detect it.
[0012] Preferably, the water collecting tank is of a conical structure. It can better gather water for the liquid level sensor to detect it.
[0013] Preferably, a distance for collecting water is left between the drain pipe and the liquid level sensor and the bottom of the water collecting tank. So that part of the water can be collected at the bottom of the water collecting tank for detection, and then the leakage situation can be obtained. At the same time, the excess water can be discharged through the drain pipe.
[0014] Preferably, the drain pipe is provided with a hydrophobic breathable membrane. When there is a small leakage, the hydrophobic breathable membrane can block the water body from flowing out to the outside, achieving the effect of leak prevention. When there is a large-scale leakage and the water in the water collecting tank is too much, the hydrophobic breathable membrane at the end of the drain pipe will quickly increase the pressure and discharge the excess water body, ensuring that the cavity will not expand and cause damage to the device and affect the normal operation, and ensuring the long-term stable operation of the device.
[0015] Preferably, the leak-proof section is the pipe flange connection. The flange is the place where the pipeline is most likely to leak water. Setting it at this place can more accurately detect the water leakage situation.
[0016] Preferably, the outer shell is a cylindrical member sleeved around the periphery of the flange, and both ends of the cylindrical member are connected to the outer wall of the pipeline. This facilitates the installation of the outer shell.
[0017] Preferably, rubber seals are provided between both ends of the cylindrical member and the outer wall of the pipeline. This improves the sealing performance.
[0018] Advantages of the present utility model:
[0019] By adopting the outer shell and the water collecting tank, water leakage can be collected, and then detected by the liquid level sensor, so that it is more convenient to obtain whether there is leakage. It can also detect small-scale water leakage. At the same time, the information is transmitted to the staff through the wireless transmission method, enabling remote acquisition of the water leakage situation, reducing the work intensity and improving the work efficiency. The drain pipe provided with the water transmission and breathable membrane can discharge the water inside the housing when there is too much accumulated water, which can avoid the damage of the instrument caused by the accumulated water on the inner wall while ensuring the detection of water leakage.
[0020] Compared with the traditional acoustic wave, gas and optical fiber detection technologies, the pressure detection technology of the present utility model is simpler and easier to implement, with lower costs, and is not easily interfered by the external environment, improving the sensitivity and accuracy of detection. A solar panel is installed on the upper part of the outer shell to provide continuous power supply for the pressure sensor and the control system. This design not only realizes energy conservation and environmental protection, but also enhances the independence and reliability of the device, ensuring that the system can operate stably for a long time under various environmental conditions. The water collecting tank adopts a drain pipe design to timely drain the leaked water body, preventing equipment damage caused by excessive accumulated water, and further improving the durability and service life of the device. It effectively improves the reliability and adaptability of the water supply pipeline leakage detection, and is applicable to various above-ground installed water supply systems.

[0028] To deepen the understanding of the present utility model, the following will further describe the present utility model in detail with reference to the drawings and embodiments. The embodiment is only used to explain the present utility model and does not limit the protection scope of the present utility model.
[0029] Embodiment
[0030] As Figure 1 and Figure 2 shown, a leakage prevention monitoring device for a water supply pipeline includes a housing 4 arranged outside the leakage prevention section of the pipeline 5; a water collecting tank 7 is arranged at the bottom of the housing 4, and the water collecting tank 7 is provided with a drain pipe 8 and a liquid level sensor 6.
[0031] In this solution, the housing 4 is arranged outside the leakage prevention section. If there is a water leakage in the leakage prevention section, the water will drain into the housing 4. Since the housing 4 is provided with a water collecting tank 7, the water will first flow into the water collecting tank 7. The water collecting tank 7 is provided with a drain pipe 8 and a liquid level sensor 6. When the liquid level sensor 6 detects an increase in the water level, it can send out a signal to the outside so that the staff can know for maintenance. Before the staff arrives, the leaked water can be discharged outward through the drain pipe 8.
[0032] It includes a solar cell module and a controller 3. The solar cell module is fixed to the housing 4 through a bracket 2. The controller 3 is provided with a wireless transmission module. The controller 3 is electrically connected to the solar cell module and the liquid level sensor 6 respectively. The solar cell module can stably supply power to the controller 3 and the liquid level sensor 6, and can ensure the normal operation of electrical components outdoors. When the liquid level sensor 6 detects an increase in the liquid level, it transmits the information to the staff through the wireless transmission module so that the staff can remotely monitor the state of the pipeline 5. The controller adopts the model ESP8266.
[0033] The liquid level sensor 6 is a float type liquid level gauge. It has accurate detection and more reliable use.
[0034] Combined with Figure 3As shown, the water collecting tank 7 is a V-shaped tank with a smaller bottom and a larger top. The drain pipe 8 and the liquid level sensor 6 are arranged on the side wall of the V-shaped tank. The V-shaped tank can better collect water so that the liquid level sensor 6 can detect it.
[0035] The water collecting tank 7 is of a conical structure. It can better collect water so that the liquid level sensor 6 can detect it.
[0036] A distance for collecting water is left between the drain pipe 8 and the liquid level sensor 6 and the bottom of the water collecting tank 7. So that part of the water can be collected at the bottom of the water collecting tank 7 for detection, and then the leakage situation can be obtained. At the same time, the excess water can be discharged through the drain pipe 8.
[0037] The drain pipe 8 is provided with a hydrophobic breathable membrane 10. This design can ventilate, making the air pressure inside and outside the cavity the same. Even if there is water accumulation in the cavity, the air pressure inside and outside is also the same, avoiding excessive pressure affecting the expansion of the cavity. When there is a small leak, the hydrophobic breathable membrane 10 can block the water body from flowing out to the outside, achieving the effect of leak prevention. When there is a large-scale leak and there is too much water accumulation in the water collecting tank 7, the hydrophobic breathable membrane 10 at the end of the drain pipe 8 will discharge the excess water due to the rapid increase in pressure, ensuring that the cavity will not expand, causing damage to the device and affecting normal operation, and ensuring the long-term stable operation of the device.
[0038] Combined with Figure 4 As shown, the leak-proof section is the flange 9 connection of the pipe 5. The flange 9 is the place where the pipe 5 is most likely to leak water. Setting it here can more accurately detect the water leakage situation.
[0039] The outer shell 4 is a cylindrical part sleeved around the flange 9, and both ends of the cylindrical part are connected to the outer wall of the pipe 5. It is convenient to install the outer shell 4.
[0040] A rubber seal is provided between both ends of the cylindrical part and the outer wall of the pipe 5. To improve the sealing performance.
[0041] Advantages of the present utility model:
[0042] By using the outer shell 4 and the water collecting tank 7, water leakage can be collected, and then the liquid level sensor 6 is used for detection, so that it is more convenient to obtain whether there is leakage. It can also detect small-scale water leakage. At the same time, combined with the wireless transmission method, the information is transmitted to the staff, and the water leakage situation can be remotely obtained, reducing the work intensity and improving the work efficiency. The drain pipe 8 provided with a water-permeable breathable membrane can discharge the water inside the shell when there is too much water accumulation, and can avoid the inner wall from being damaged by water accumulation while ensuring the detection of water leakage.
[0043] Compared with traditional acoustic wave, gas, and fiber optic detection technologies, the pressure detection technology of the present utility model is more simple and feasible, with lower costs, and is not easily interfered by the external environment, improving the sensitivity and accuracy of detection. A solar panel is installed on the upper part of the housing to provide continuous power supply for the pressure sensor and control system. This design not only achieves energy conservation and environmental protection but also enhances the independence and reliability of the device, ensuring that the system can operate stably for a long time under various environmental conditions. The water collection tank adopts a drain pipe design to timely drain the leaked water body, preventing equipment damage caused by excessive water accumulation, and further improving the durability and service life of the device. It effectively improves the reliability and adaptability of water supply pipeline leakage detection and is applicable to various above-ground installed water supply systems.
