Description

Technical Field

[0001] The present invention relates to the technical field of pipeline anti-leakage detection, in particular to an anti-leakage detection device for municipal road water supply and drainage pipelines. Background Art

[0002] Municipal water supply and drainage pipelines are pipelines that transport and distribute industrial water supply and domestic drinking water, and collect, transport and discharge industrial wastewater, domestic sewage and rainwater. Water supply and drainage pipeline projects are an integral part of the water supply and drainage system and play an important role in the entire water supply and drainage system. Water supply and drainage pipelines include trunk pipes, branch pipes and pipelines leading to treatment plants. No matter whether they are built on the streets or anywhere else, as long as they are functional pipelines, they need to be regularly inspected for leaks. In order to reduce the difficulty of leak detection, professional water supply and drainage pipeline anti-leakage detection devices will be used for leak detection.

[0003] For example, a Chinese patent, publication number: CN 114894394 A, discloses a device for detecting leakage of municipal road water supply and drainage pipelines, specifically relating to the technical field of detecting leakage of water supply and drainage pipelines. The present invention comprises a housing and a computer, a first rotating shaft is provided inside the housing, rollers are provided at both ends of the first rotating shaft, a second rotating shaft is provided above the first rotating shaft, a transmission belt is provided between the second rotating shaft and the first rotating shaft, a turntable is provided on the second rotating shaft, a baffle is provided on the turntable, a through hole is provided at the bottom of the housing, a leak detector is provided above the through hole, a spring is provided on the leak detector, a limit plate is provided on the spring, a first connecting rod is provided on the limit plate, a second connecting rod is rotatably connected to the first connecting rod, a third connecting rod is rotatably connected between the second connecting rod and the housing, and the second connecting rod is located on the motion trajectory of the baffle.

[0004] This invention uses a drive motor and other components to allow inspectors to continuously inspect along the road surface of the pipeline. However, the water supply and drainage pipelines are very long, requiring continuous work over long distances. This causes fatigue among inspectors, who need frequent breaks during the leak detection process, resulting in slow detection and a heavy workload for inspectors. Therefore, the present invention proposes a municipal road water supply and drainage pipeline anti-leakage detection device to address the above-mentioned issues. Summary of the Invention

[0005] The present invention aims to provide a municipal road water supply and drainage pipeline anti-leakage detection device to solve the problem that existing technical means require inspectors to conduct inspections along the road surface of the pipeline, and need to work continuously for a long distance, which causes fatigue of the inspectors and requires frequent rest during the leak detection process, resulting in slow leak detection speed and heavy workload for inspectors.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the present invention is as follows: a municipal road water supply and drainage pipeline anti-leakage detection device, comprising a water supply and drainage pipeline, a plurality of detection devices are placed in the water supply and drainage pipeline, the detection device comprises a circular body, a plurality of electric control cylinders are installed in the circular body along its circumference, the output shafts of the plurality of electric control cylinders are fixedly connected to a first connecting rod, the ends of the plurality of first connecting rods away from the electric control cylinders are fixedly connected to a first support portion, a plurality of drive motors are installed in the circular body along its circumference, the output shafts of the plurality of drive motors are coaxially connected to a main bevel gear, and a plurality of drive motors are installed on the circular body along its circumference. There are several rollers, part of the roller body is located outside the ring body, one end of the roller shaft is rotatably connected to the inside of the ring body, the other end of the roller shaft is coaxially connected to the slave bevel gear, the main bevel gears are engaged with the slave bevel gears, a water pressure detector and a flow rate detector pointing to the center of the circle are installed on the ring body, a battery and a controller are installed inside the ring body, the controller, several electric control cylinders, water pressure detectors, flow rate detectors and several drive motors are electrically connected to the battery respectively, and the battery, several electric control cylinders, water pressure detectors, flow rate detectors and several drive motors are respectively connected to the controller signal.

[0007] Principle of the basic scheme: The detection device of the present invention controls several electric control cylinders through a controller to output the first connecting rod outward, so that the first support part connected to the first connecting rod circumferentially presses against the side wall of the water supply and drainage pipe, thereby fixing the entire detection device in the water supply and drainage pipe, and then uses the water pressure detector and flow rate detector installed on the inside of the annular body to respectively detect the flow rate and water pressure of the water flowing from the middle of the annular body. When the water supply and drainage pipe is broken at a certain point, the water flow in the water supply and drainage pipe will leak outward through the rupture. At this time, the water flow rate and water pressure detected by the detection device downstream of the rupture will decrease, thereby locating the rupture upstream of the detection device; by retracting the first support part and starting the drive motor, the roller rolls and drives the detection device to move upstream, thereby accurately locating the position of the rupture.

[0008] The beneficial effects achieved are: the detection device proposed in the present invention enables the detection device to continuously detect water flow inside the water supply and drainage pipe through the cooperation of the electric control cylinder, the driving motor and other components, and can be applied to water supply and drainage pipes with long lengths, and does not require detection personnel to manually operate the detection step by step along the water supply and drainage pipe; the detection device proposed in the present invention has two working states, one is to fix the detection device in the water supply and drainage pipe through the first support part, and locate the position of the rupture through the pressure difference formed by the rupture between different detection devices; the second is to be able to move the detection device in the water supply and drainage pipe through the driving motor, and to adjust the distance between adjacent detection devices as needed, and to switch the two states of the detection device freely by manual operation at the remote end, so that the rupture can be accurately located, which greatly improves the speed of leak detection and reduces the workload of detection personnel.

[0009] Furthermore, a plurality of water inlets are provided on the side wall of the annular body, and the plurality of water inlets are connected to a plurality of water pressure conversion chambers provided inside the annular body. A vertical second connecting rod is slidably connected in the plurality of water pressure conversion chambers, the lower ends of the second connecting rods are fixedly connected to the pressure blocks, and the upper ends of the second connecting rods are fixedly connected to the second support parts. The water pressure conversion chambers are connected to water outlets, and the plurality of water outlets are located on the side wall of the annular body away from the water inlet.

[0010] The principle of the basic solution: Through several water inlets provided on the side wall of the annular body, the water flow inside the supply and discharge pipes can flow into the water pressure conversion chamber. The water flow in the water pressure conversion chamber applies water pressure to the pressure block, causing the second connecting rod to slide upward, and causing the several second support parts on the circumference of the annular body to slide outward and against the inner wall of the pipe, thereby supporting the entire detection device.

[0011] The beneficial effect achieved is: by converting the water pressure of the water flow in the supply and discharge pipes, the stability of the entire detection device is enhanced, and the detection device is prevented from being washed away by the water flow.

[0012] Furthermore, the environment in which the municipal road water supply and drainage pipelines are located is used as a distinction. According to the probability of pipeline damage, the pipelines are divided into easy leakage areas, moderate leakage areas and low leakage areas. Different numbers of detection devices are reasonably placed in the easy leakage areas, moderate leakage areas and low leakage areas.

[0013] The principle and beneficial effects of the basic solution: By distinguishing between areas prone to leakage, areas with moderate leakage, and areas with low leakage, the goal of low-cost and high-efficiency leakage detection can be achieved. In addition, by centrally maintaining and replacing the detection devices in areas prone to leakage at a regular interval, long-term and high-accuracy detection can be achieved.

[0014] Furthermore, a communicator is installed in each of the detection devices, the communicator is connected to the controller by signal, the communicator is connected to the server by signal, and the server is wirelessly connected to the client.

[0015] The principle and beneficial effects of the basic solution: Through the communicators installed in several detection devices, the data information collected by each component in the detection device can be sent to the customer service end. The customer service end will organize the received data information and send it to the customer service end. The staff will understand the data information of each detection device through the customer service end, so that they can locate the detection device next to the leakage position of the water supply and drainage pipeline. The staff will then control the detection device to move to the rupture through the customer service end, server and communicator, so that they can accurately locate the leakage position of the water supply and drainage pipeline, which is convenient for maintenance personnel to repair the leaking water supply and drainage pipeline. Through remote control, the workload of the staff is reduced and the efficiency of detection is increased.

[0016] Furthermore, the controller, the plurality of electric control cylinders, the water pressure detector, the flow rate detector, the battery and the plurality of driving motors are all sheathed with sealing layers on their outer sides.

[0017] Principle and beneficial effects of the basic solution: The sealing layer provided on the outside of each component can effectively protect each component and increase the service life of the entire detection device.

[0018] Furthermore, the controller is one of an LG programmable controller, a PLC controller, and a CPU microcontroller.

[0019] Furthermore, the communicator is one of an NB-LOT communicator, a LORA communicator, and a ZigBee communicator.

[0020] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

The water flow in the water pressure conversion chamber 16 applies water pressure to the pressure block 17, causing the second connecting rod 18 to slide upward, so that the several second support parts 19 circumferentially of the annular body 4 slide outward and against the inner wall of the pipe, thereby supporting the entire detection device 2.
