Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a leakage monitoring and drainage device for water conservancy projects. Background Technology

[0002] In water conservancy projects, pipeline systems are a crucial component, used for water transport and diversion. However, due to various reasons such as material aging, improper construction, and external corrosion, leaks may occur on the outer walls of pipelines. Pipeline leaks not only lead to water waste but can also cause serious consequences such as soil instability and structural damage. Therefore, timely and effective monitoring and treatment of pipeline leaks are of paramount importance.

[0003] Existing pipeline leakage monitoring devices are often single-function and cannot simultaneously collect, drain, and settle leaking water and impurities. Furthermore, when a leak is detected, the information feedback is not timely or intuitive enough. Utility Model Content

[0004] This utility model provides a leakage monitoring and drainage device for water conservancy projects, which solves the problems of limited pipeline leakage monitoring function, difficulty in effectively collecting and draining water, and untimely information feedback in the prior art.

[0005] The technical solution adopted by this utility model is: a water collection and drainage device for leakage monitoring in water conservancy projects, including a water collection cover for clamping onto the outer wall of a pipe, wherein an annular sealed space is formed between the inner wall of the water collection cover and the outer wall of the pipe, the water collection cover is composed of a separable upper ring cover and a lower ring cover joined together, and a fixing block is provided on both the upper ring cover and the lower ring cover, and the two are connected by fastening bolts passing through the fixing blocks; the bottom of the lower ring cover is provided with an integrally formed water collection cavity, the bottom of the water collection cavity extends downward to form a sedimentation bucket, a vertical rod is provided in the water collection cavity, a sensor is provided at the top of the vertical rod, and a float that can rise and fall with the water level is sleeved on the vertical rod.

[0006] Preferably, the side wall of the water collection chamber is connected to a drain pipe, and the drain pipe is equipped with a solenoid valve.

[0007] Preferably, an audible and visual alarm is installed on the outer wall of the water collection cavity.

[0008] Preferably, the bottom outlet of the settling hopper is connected to a manual drain valve.

[0009] Preferably, an elastic sealing strip is embedded on the contact surface between the upper and lower ring covers and the outer wall of the pipe.

[0010] Preferably, a sealing structure is provided on the mating surface of the upper ring cover and the lower ring cover. The sealing structure includes an elastic sealing strip II disposed at the bottom of the upper ring cover and a sealing groove disposed at the top of the lower ring cover for accommodating the elastic sealing strip II.

[0011] Preferably, the sensor is electrically connected to the solenoid valve and the audible and visual alarm, respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By clamping the water collection hood to the outer wall of the pipe, a ring-shaped sealed space is formed with the outer wall of the pipe, which can effectively collect any leakage water that may occur outside the pipe. The float in the water collection chamber rises and falls with the leakage water level, and drives the sensor to work through the upright, which can realize accurate monitoring of the leakage water level.

[0014] 2. The sensor is electrically connected to the solenoid valve and the audible and visual alarm. When the leakage water level reaches the set threshold, the solenoid valve can be automatically opened to drain the water, and the audible and visual alarm will issue an early warning to ensure timely handling.

Detailed Implementation

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] like Figures 1-4As shown, this utility model provides a leakage monitoring and drainage device for water conservancy projects, including a water collection cover 1. The water collection cover 1 is used to clamp onto the outer wall of a pipeline in the water conservancy project. The water collection cover 1 is composed of a detachable upper ring cover 101 and a lower ring cover 102 connected together. The upper ring cover 101 and the lower ring cover 102 are designed to surround a part of the pipeline, and an annular sealed space is formed between the inner wall and the outer wall of the pipeline for collecting leakage water from the pipeline. For easy installation and disassembly, both the upper ring cover 101 and the lower ring cover 102 are provided with fixing blocks 4. These two fixing blocks 4 are provided with through holes for fastening bolts 401 to pass through. By tightening the fastening bolts 401, the upper ring cover 101 and the lower ring cover 102 can be firmly connected together, thereby clamping the water collection cover 1 onto the outer wall of the pipeline.

[0023] The bottom of the lower ring cover 102 is integrally formed with a water collection chamber 2. The water collection chamber 2 is a container for collecting leaked water. The bottom of the water collection chamber 2 extends downward to form a sedimentation hopper 201. The sedimentation hopper 201 is designed to settle the mud, sand and other impurities carried in the leaked water, preventing them from clogging the water collection chamber 2 and the subsequent drainage pipes.

[0024] Inside the water collection chamber 2, there is a vertical rod 5. This rod 5 is vertically fixed to the bottom or side wall of the water collection chamber 2 and extends upwards to near the top of the chamber. A sensor 6 is installed at the top of the rod 5. To enable the sensor 6 to respond to changes in the leakage water level, a float 7 is fitted onto the rod 5. The float 7 has a density less than water, allowing it to float on the water surface and move up and down with changes in the water level. When leaking water enters the water collection chamber 2, the float 7 rises with the increasing water level, activating the sensor 6 on the rod 5 to detect the current water level.

[0025] To facilitate the drainage of leaked water, a drain pipe 8 is connected to the side wall of the water collection chamber 2. The drain pipe 8 can be connected to a drainage system or other collection point as needed. A solenoid valve 9 is installed on the drain pipe 8. The solenoid valve 9 controls the opening and closing of the drain pipe 8, thereby controlling the discharge of leaked water.

[0026] To promptly alert management personnel to leaks, an audible and visual alarm 10 is installed on the outer wall of the water collection chamber 2. When the sensor 6 detects that the leak level has reached a preset alarm threshold, the audible and visual alarm 10 can be triggered by an electrical signal to emit an audible and visual signal, reminding management personnel to handle the situation promptly.

[0027] To facilitate the cleaning of silt accumulated in the settling hopper 201, a manual drain valve 11 is connected to the bottom outlet of the settling hopper 201. When cleaning is required, the manual drain valve 11 can be opened to discharge the settled silt.

[0028] To improve the sealing performance of the water collection cover 1 and prevent external rainwater or other impurities from entering, elastic sealing strips 12 are embedded on the contact surfaces of the upper ring cover 101 and the lower ring cover 102 with the outer wall of the pipe. These elastic sealing strips 12 can fit tightly against the outer wall of the pipe to form an effective seal.

[0029] To ensure a tight seal at the joint between the upper ring cover 101 and the lower ring cover 102, a sealing structure is provided on their mating surfaces. This sealing structure includes a second elastic sealing strip 13 located at the bottom of the upper ring cover 101 and a sealing groove 14 located at the top of the lower ring cover 102 to accommodate the second elastic sealing strip 13. When the upper ring cover 101 and the lower ring cover 102 are mated, the second elastic sealing strip 13 is pressed into the sealing groove 14, forming a good seal.

[0030] Working principle:

[0031] When installing the device, for pipes with visible cracks or localized damage, install the device directly on the cracked or damaged area for focused monitoring. Alternatively, the device can be directly clamped to the joint, allowing immediate collection of water seeping from any point along the joint. For long-distance pipelines where full coverage is not possible, select representative sections or install a device at intervals to form a monitoring network. Once an alarm is triggered at a point, the location of the leak can be roughly pinpointed.

[0032] When a leak occurs in the pipe, the leaking water collects from the outer wall of the pipe and is collected by the water collection hood 1, which is clamped to the outer wall of the pipe. The leaking water flows into the water collection chamber 2 through the lower part of the water collection hood 1. As the leaking water continues to accumulate, the water level in the water collection chamber 2 gradually rises, and the float 7 rises accordingly. The rise of the float 7 activates the sensor 6 on the upright 5, which detects the current water level.

[0033] If the leakage continues to increase, causing the water level to rise rapidly, sensor 6 will send a signal to solenoid valve 9 and audible and visual alarm 10 when the water level reaches a preset threshold. Upon receiving the signal, solenoid valve 9 will automatically open, allowing the leaking water to be discharged through drain pipe 8. At the same time, audible and visual alarm 10 will emit an audible and visual signal to alert management personnel.

[0034] During the collection and drainage of leaked water, the sedimentation hopper 201 at the bottom of the collection chamber 2 will settle the mud and sand and other impurities in the leaked water, keeping the collection chamber 2 and the drainage pipeline clean. When the mud and sand in the sedimentation hopper 201 accumulate to a certain level, it can be cleaned by opening the manual drain valve 11.
