Description

Technical Field

[0001] This utility model relates to the field of water supply pipeline detection technology, specifically to a water supply pipeline leakage monitoring and early warning device. Background Technology

[0002] Water supply pipes are suitable for domestic water supply and drainage, chemical industry, sewage discharge, waterworks renovation, and national water conservancy projects. After a period of use, existing municipal water supply pipes are prone to leakage at their connections, leading to water waste. To detect leaks promptly, leakage detection devices are typically installed at these connections. Currently, water supply pipes come in various outer diameters, while existing leakage detection devices have fixed installation diameters, making them unsuitable for simultaneous installation on pipes of different diameters. This limits their applicability and makes installation inconvenient. Therefore, improvements to the existing technology are necessary.

[0003] For example, patent document CN 220582248 U discloses a leak detection device for municipal road water supply and drainage pipelines, but the leak detection device has a complex structure, making it inconvenient to process, manufacture, and control costs. Utility Model Content

[0004] In view of the problems and shortcomings of the existing technology, this utility model provides a water supply pipeline leakage monitoring and early warning device.

[0005] The technical solution of this utility model is as follows:

[0006] A water supply pipeline leakage monitoring and early warning device includes a lower support, an upper support, and a connector;

[0007] The lower and upper supports have horizontally bottomed V-groove positioning parts, which are connected to the water supply pipe by a connector with reverse threads;

[0008] A point-type water immersion sensor is installed on the positioning part of the lower support. The detection element of the point-type water immersion sensor passes through the top surface of the lower support and is exposed below the water supply pipe.

[0009] According to a specific embodiment, the lower support has a positioning part with a horizontally bottomed V-shaped groove at its top, and horizontal mounting parts are symmetrically arranged on both sides. The positioning part has a vertically penetrating mounting hole at its center for mounting a point-type water immersion sensor. The mounting part has a first connecting hole for mating with a connector. Specifically, the positioning part and the mounting part are integrally formed. The top surface of the positioning part is machined with a V-shaped positioning surface with a horizontal bottom, for mating with the outer diameter of the water supply pipe to accommodate different pipe diameters. The mounting part has a vertically penetrating first connecting hole.

[0010] Furthermore, the mounting holes are stepped holes that gradually increase in size downwards, facilitating the fixing of the point-type water immersion sensor from the bottom. This allows the data cable of the point-type water immersion sensor to be led out from below and connected to the monitoring unit, enabling leakage detection and alarm.

[0011] The upper support has a positioning part with a horizontally bottomed V-groove at its top, and horizontal mounting parts are symmetrically arranged on both sides. Each mounting part has a second connecting hole for mating with a connector. Specifically, the positioning part and the mounting part are integrally formed. The top surface of the positioning part is machined with a V-shaped positioning surface with a horizontal bottom, for mating with the outer diameter of the water supply pipe to accommodate different pipe diameters. The mounting part has a second connecting hole that runs vertically through it.

[0012] Furthermore, the first connecting hole or the second connecting hole is a threaded hole, and the threads rotate in opposite directions.

[0013] The connector includes an adjusting section in the middle and a first connecting section and a second connecting section symmetrically arranged radially along the adjusting section. The first and second connecting sections have threads with opposite directions of rotation. The first connecting section mates with a first connecting hole, and the second connecting section mates with a second connecting hole. A tool hole is provided at the center of the adjusting section for mates with an installation tool. The tool hole is an internal hexagonal hole.

[0014] During installation, insert the hex wrench into the tool hole and turn it clockwise. The connector rotates within the first and second connecting holes. Since the threads of the first and second connecting parts on its upper and lower sides rotate in opposite directions, the lower and upper supports that it mates with move towards each other, clamping the pipe and thus achieving fixation. During disassembly, rotate the hex wrench counterclockwise, driving the connector to rotate counterclockwise within the first and second connecting holes. This causes the lower and upper supports that it mates with to move away from each other, loosening the pipe and thus achieving disassembly.

[0015] The beneficial effects of this utility model are:

[0016] It consists only of a lower support, an upper support, and a connector, featuring a simple structure that is easy to process and has low manufacturing costs. Both the lower and upper supports have horizontally oriented V-groove positioning parts. These are attached to the water supply pipe via connectors with reverse threads. Tightening or loosening the lower and upper supports on the pipe can be achieved by rotating the connectors with an external hex wrench, making installation and disassembly convenient. A point-type water immersion sensor is installed at the bottom of the V-groove positioning surface of the lower support to improve the timeliness of leak detection. Attached Figure Description

[0021] The technical means adopted to achieve the intended purpose of this utility model will be further described below with reference to the accompanying drawings of the embodiments of this utility model.

[0022] See Figure 1 As shown, a water supply pipeline leakage monitoring and early warning device includes a lower support 1, an upper support 2, and a connector 3.

[0023] The lower support 1 and the upper support 2 have V-groove positioning parts 11 with horizontal bottoms, which are connected to the water supply pipe by a connector 3 with reverse threads.

[0024] A point-type water immersion sensor 4 is provided on the positioning part 11 of the lower support 1. The detection element of the point-type water immersion sensor passes through the top surface of the lower support 1 and is exposed below the water supply pipe.

[0025] See Figure 2 As shown, according to a specific embodiment, the lower support 1 has a positioning part 11 with a horizontally bottomed V-shaped groove at its top, and horizontal mounting parts 12 are symmetrically arranged on both sides. The center of the positioning part 11 has a vertically penetrating mounting hole 111 for mounting a point-type water immersion sensor 4. The mounting part has a first connecting hole 121 for mating with the connector 3. Specifically, the positioning part and the mounting part are integrally formed. The top surface of the positioning part 11 is machined with a V-shaped positioning surface with a horizontal bottom surface for mating with the outer diameter of the water supply pipe to accommodate different pipe diameters. The mounting part is machined with a vertically penetrating first connecting hole 121.

[0026] Furthermore, mounting hole 111 is a stepped hole that gradually increases in diameter downwards, facilitating the fixing of the point-type water immersion sensor from the bottom. This allows the data cable of the point-type water immersion sensor to be led out from below and connected to the monitoring unit, enabling leakage detection and alarm.

[0027] See Figure 1 As shown, the upper support 2 has a positioning part 11 with a horizontal bottom V-shaped groove at its top, and horizontal mounting parts 12 are symmetrically arranged on both sides. The mounting parts are provided with a second connecting hole 21 for mating with the connector 3. Specifically, the positioning part and the mounting part are integrally formed. The top surface of the positioning part is machined with a V-shaped positioning surface with a horizontal bottom, which is used to fit with the outer diameter of the water supply pipe to accommodate different pipe diameters. The mounting part is machined with a second connecting hole 21 that runs vertically through the pipe.

[0028] Furthermore, the first connecting hole 121 or the second connecting hole 21 is a threaded hole, and the threads are rotated in opposite directions.

[0029] See Figure 3 The connector 3 includes an adjusting portion 31 in the middle and a first connecting portion 32 and a second connecting portion 33 arranged radially symmetrically along the adjusting portion 31. The first connecting portion 32 and the second connecting portion 33 are provided with threads in opposite directions. The first connecting portion 32 mates with the first connecting hole 121, and the second connecting portion 33 mates with the second connecting hole 21. A tool hole 331 is provided at the center of the adjusting portion 31 for mates with an installation tool. The tool hole 331 is an internal hexagonal hole.

[0030] During installation, insert the hex wrench into the tool hole 331 and rotate it clockwise. The connector 3 rotates within the first connecting hole 121 and the second connecting hole 21. Since the threads of the first connecting part 32 and the second connecting part 33 on its upper and lower sides are opposite, the lower support 1 and the upper support 2 that cooperate with it move towards each other, clamping the pipe and thus achieving fixation. During disassembly, rotate the hex wrench counterclockwise, driving the connector 3 to rotate counterclockwise within the first connecting hole and the second connecting hole 21, causing the lower support 1 and the upper support 2 that cooperate with it to move away from each other, loosening the pipe and thus achieving disassembly.
