Description

Technical Field

[0001] This utility model relates to the field of water supply systems, specifically a water supply system pipe burst monitoring and alarm device. Background Technology

[0002] As a crucial component of urban infrastructure, the safe and stable operation of water supply systems directly impacts residents' daily lives and production activities. Over long periods of use, water pipes are prone to bursting due to environmental factors, pipe aging, pressure fluctuations, and other reasons. This leads to significant water waste and can cause environmental damage and facility disruption. Pipe bursts not only increase maintenance costs but can also disrupt water supply, negatively impacting social production and residents' lives. Therefore, timely detection and early warning of pipe bursts in water supply systems are of paramount importance for ensuring water supply safety, reducing economic losses, and improving the operational efficiency of water supply systems.

[0003] In existing technologies, during water pipe monitoring, when the water pressure inside the pipe continuously increases, it may cause the pipe to burst, posing a serious safety hazard to the water supply system. Traditional monitoring devices usually only have an alarm function, which can sound an alarm when the water pressure is too high to remind staff to pay attention. However, these devices often lack an effective pressure relief mechanism and cannot take timely measures to release pressure when the water pressure is too high, thereby preventing the pipe from bursting. This design that relies solely on alarm devices has significant shortcomings, because alarm devices can only issue warnings after a problem occurs and cannot intervene when the water pressure in the pipe increases. Utility Model Content

[0004] The purpose of this invention is to provide a water supply system pipe burst monitoring and alarm device to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A water supply system pipe burst monitoring and alarm device includes a water pipe body, flange bodies are fixedly connected to both ends of the outer wall of the water pipe body, a water pressure gauge for viewing water pressure is fixedly connected to the top of the water pipe body, a water pressure detection head is fixedly connected to the detection end of the water pressure gauge and extends into the interior of the water pipe body, a pressure reducing mechanism for reducing water pressure is provided at the top of the water pipe body, and an alarm mechanism for excessive water pressure is provided on the outer wall of the water pipe body.

[0007] Preferably, the pressure reducing mechanism includes an inner box fixedly connected to the top of the water pipe body, a water storage tank fixedly connected to the top of the water pipe body on one side of the inner box, and the water storage tank is located between the water pressure gauge and the inner box. A first spring is fixedly connected to the top of the inner box, and a first pressure plate is fixedly connected to the end of the first spring.

[0008] Preferably, a second spring is fixedly connected to the inner top of the inner box, a second pressure plate is fixedly connected to the end of the second spring, a threaded sleeve is fixedly connected to the center of the upper top of the second pressure plate, a threaded rod is threaded inside the threaded sleeve, and the end of the threaded rod extends to the upper top of the inner box, and a throttle is fixedly connected to the extended end of the threaded rod.

[0009] Preferably, a sealing seat is fixedly connected to the inner top of the inner box on the outer wall of the threaded rod, and the sealing seat is rotatably sleeved with the threaded rod. A water supply pipe for communicating with the interior is fixedly connected between the inner box and the water storage tank. A drain pipe is fixedly connected to the discharge end of the water storage tank, and an electromagnetic one-way valve is installed on the outer wall of the drain pipe.

[0010] Preferably, a flow monitoring screen is fixedly connected to the top of the water pipe body on the side of the water pressure gauge away from the water storage tank, and a flow detection head is fixedly connected to the detection end of the flow monitoring screen, with the flow detection head extending into the interior of the water pipe body.

[0011] Preferably, the alarm mechanism includes fixed brackets symmetrically and fixedly connected to the outer wall of the water pipe body. An audible and visual alarm is fixedly connected inside the two fixed brackets. A switch and a receiving module are respectively installed on the top of the audible and visual alarm, and the switch and the receiving module are symmetrically arranged.

[0012] Preferably, the first pressure plate is slidably connected to the inner wall of the water storage tank, and the second pressure plate is slidably connected to the inner wall of the inner tank.

[0013] The beneficial effects of this utility model are:

[0014] This invention incorporates a pressure-reducing mechanism. When the water pressure inside the water pipe exceeds a certain limit, the mechanism is activated by the operator. This involves rotating a threaded rod, which, in conjunction with a threaded sleeve, causes the second pressure plate to rise. The second pressure plate then presses against the sealing seat and moves above the end of the water pipe, allowing water to flow into the inner tank and then into the storage tank via the water pipe. As the liquid level increases, it applies pressure to the first pressure plate and stretches the first spring. At this point, the first pressure plate is lower than the drain pipe, allowing water to flow back into the water pipe. Because the liquid passes through the pressure-reducing mechanism, the pressure inside the water pipe is reduced, preventing damage to the water pipe. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, a water supply system pipe burst monitoring and alarm device includes a water pipe body 1, flange bodies 2 fixedly connected to both ends of the outer wall of the water pipe body 1, a water pressure gauge 4 for viewing water pressure fixedly connected to the upper top of the water pipe body 1, a water pressure detection head 41 fixedly connected to the detection end of the water pressure gauge 4, and the water pressure detection head 41 extending into the interior of the water pipe body 1, a pressure reducing mechanism 3 for reducing water pressure is provided at the upper top of the water pipe body 1, and an alarm mechanism for excessive water pressure is provided on the outer wall of the water pipe body 1.

[0023] It should be noted that the water pressure detection head 41, which is fixedly connected to the detection end of the water pressure gauge 4, extends into the interior of the water pipe body 1 to sense changes in water pressure in the water pipe in real time. Once an abnormal change in water pressure occurs, the water pressure detection head 41 can promptly provide data feedback, providing real-time basis for the alarm mechanism. At the same time, the pressure reducing mechanism 3 set at the top of the water pipe body 1 can automatically adjust when the water pressure is too high, preventing the pipe from bursting due to excessive water pressure. The water pressure alarm mechanism set on the outer wall of the water pipe body 1 can trigger the alarm system when the water pressure exceeds the set value, promptly reminding the operator to take appropriate measures to avoid equipment damage or other safety hazards caused by prolonged high-pressure operation. The water pressure detection head 41 can use a water pressure sensor as the main detection method, and its model can be CYG1001 (not specifically specified).

[0024] As a technical optimization of this utility model, the pressure reducing mechanism 3 includes an inner box 32 fixedly connected to the top of the water pipe body 1. A water storage tank 31 is fixedly connected to the top of the water pipe body 1 on one side of the inner box 32. The water storage tank 31 is located between the water pressure gauge 4 and the inner box 32. A first spring 311 is fixedly connected to the top of the inner end of the water storage tank 31. A first pressure plate 312 is fixedly connected to the end of the first spring 311.

[0025] It should be noted that the design of the inner tank 32 enables it to effectively accommodate and regulate the pressure of the water flow. The water storage tank 31 acts as a buffer to regulate the water pressure, ensuring a smooth change in water pressure. The first spring 311, as a key component of the pressure reducing mechanism 3, can provide an elastic response when the water pressure is high. The first pressure plate 312 is fixedly connected to the end of the first spring 311. When the water pressure is too high, the spring can be compressed, pushing the first pressure plate 312 to move downward, thereby releasing the water in the water storage tank 31 and reducing the water pressure in the system. The elastic design of the first spring 311 ensures that the water storage tank 31 can automatically adjust according to the actual water pressure changes and effectively control the water pressure within a safe range.

[0026] As a technical optimization of this utility model, a second spring 321 is fixedly connected to the inner top of the inner box 32, a second pressure plate 322 is fixedly connected to the end of the second spring 321, a threaded sleeve 326 is fixedly connected to the center of the upper top of the second pressure plate 322, a threaded rod 324 is threaded inside the threaded sleeve 326, and the end of the threaded rod 324 extends to the upper top of the inner box 32. A handle 325 is fixedly connected to the extended end of the threaded rod 324. The first pressure plate 312 is slidably connected to the inner side wall of the water tank 31, and the second pressure plate 322 is slidably connected to the inner side wall of the inner box 32.

[0027] It should be noted that the second pressure plate 322, which is fixedly connected to the end of the second spring 321, plays a role in regulating pressure when the water pressure is too high. When the water pressure in the water pipe increases, the second spring 321 is compressed, pushing the second pressure plate 322 upward, thereby adjusting the pressure level of the system. By rotating the position of the threaded rod 324, the degree of compression of the second pressure plate 322 is changed, further refining the water pressure adjustment process. The end of the threaded rod 324 extends to the top of the inner box 32, ensuring the stability and effectiveness of the entire adjustment process. When in use, when the internal water pressure of the water pipe body 1 is in a flat state, the second pressure plate 322 is located below the port of the water supply pipe 33, while the upper end of the first pressure plate 312 is located below the water supply pipe 33.

[0028] As a technical optimization of this utility model, the inner top of the inner box 32 is fixedly connected to the outer wall of the threaded rod 324 with a sealing seat 323, and the sealing seat 323 is rotatably sleeved with the threaded rod 324. A water supply pipe 33 for communicating with the interior is fixedly connected between the inner box 32 and the water storage tank 31. A drain pipe 34 is fixedly connected to the discharge end of the water storage tank 31, and an electromagnetic one-way valve 35 is installed on the outer wall of the drain pipe 34.

[0029] It should be noted that the rotatable engagement of the sealing seat 323 and the threaded rod 324 ensures that the system maintains a tight seal when adjusting water pressure, preventing water leakage. The rotatable engagement design of the sealing seat 323 makes the adjustment of the threaded rod 324 smoother, reducing friction and resistance, and improving the accuracy and efficiency of adjustment. The electromagnetic check valve 35 installed on the outer wall of the drain pipe 34 plays an important role in the system's drainage. The electromagnetic check valve 35 can automatically control the direction of water flow, ensuring that water is discharged through the drain pipe 34 only when needed, while preventing external water from entering the system, thus ensuring the system's stability and safety.

[0030] As a technical optimization of this utility model, a flow viewing screen 5 is fixedly connected to the top of the water pipe body 1 on the side of the water pressure gauge 4 away from the water storage tank 31. A flow detection head 51 is fixedly connected to the detection end of the flow viewing screen 5, and the flow detection head 51 extends into the interior of the water pipe body 1.

[0031] It should be noted that the flow detection head 51, which is fixedly connected to the detection end of the flow display screen 5, can directly sense the water flow rate through the main body of the water pipe 1. The design of the flow detection head 51 extending into the interior of the main body of the water pipe 1 enables it to capture the actual water flow more accurately, ensuring the accuracy of the detection data. Through the real-time data acquisition of the flow detection head 51, the system can provide accurate flow information to help operators make more precise adjustments and management.

[0032] As a technical optimization of this utility model, the alarm mechanism includes fixed brackets 6 that are symmetrically fixedly connected to the outer wall of the water pipe body 1. A sound and light alarm 8 is fixedly connected inside the two fixed brackets 6. A switch 7 and a receiving module 9 are respectively installed on the top of the sound and light alarm 8, and the switch 7 and the receiving module 9 are symmetrically arranged.

[0033] It should be noted that the two fixed brackets 6 are internally connected to audible and visual alarms 8, which enable the audible and visual alarms 8 to issue an alarm in a timely manner when there is an abnormality in the water pipe system, reminding the operator to take measures. A corresponding controller can be installed on the outer wall of the water pipe body 1. The controller can establish a signal transmission channel with the water pressure gauge 4 through wires. When the water pressure inside the water pipe body 1 is too high, the transmitting module inside the water pressure gauge 4 transmits the data to the controller. The controller then establishes a signal transmission channel with the receiving module 9 on the outer wall of the audible and visual alarm 8 through wires, and the controller controls the audible and visual alarm 8 to sound the alarm.

[0034] When this utility model is in use, when the water pressure in the main body of the water pipe 1 exceeds the safety threshold due to abnormal working conditions, the water pressure gauge 4 displays the current water pressure value in real time, and the flow monitoring screen 5 monitors the instantaneous flow rate simultaneously, providing the operator with a basis for decision-making. If the water pressure continues to rise, the operator can trigger the pressure reduction process by rotating the threaded rod 324. The threaded rod 324 is driven by the handle 325 and engages with the threaded sleeve 326 to push the second pressure plate 322 to slide upward along the inner wall of the inner box 32, compressing the second spring 321. When the second pressure plate 322 moves upward to above the port of the water supply pipe 33, the high-pressure water flow in the main body of the water pipe 1 flows into the inner box 32 through the water supply pipe 33 and is further injected into the water storage tank 31 to achieve pressure release. The first pressure plate 312 in the water storage tank 31 is displaced downward by the liquid impact, stretching the first spring 311 until its bottom surface is lower than the port of the drain pipe 34.

[0035] At this time, some water in the water tank 31 flows back to the water pipe body 1 through the drain pipe 34 controlled by the electromagnetic check valve 35, forming a circulating pressure relief circuit. The rotating sealing structure of the threaded rod 324 and the sealing seat 323 ensures that the high-pressure fluid flows only through the water supply pipe 33 in one direction, avoiding the risk of leakage. By adjusting the height of the second pressure plate 322, the pressure relief rate can be precisely controlled: rotating the threaded rod 324 clockwise increases the displacement of the second pressure plate 322 and accelerates the pressure relief; rotating counterclockwise restores the initial state and terminates the pressure relief. If the water pressure is abnormally high and does not exceed the limit within 5 minutes without manual intervention, the receiving module 9 receives the over-limit signal from the water pressure gauge 4 and triggers the audible and visual alarm 8, which alerts on-site personnel through high-frequency flashing and a 90dB buzzer. The switch 7 provides a manual emergency stop function, which can cut off the alarm with one click and close the electromagnetic check valve 35 in conjunction with the alarm, to avoid excessive pressure relief and water supply interruption.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
