Description

Technical Field

[0001] This utility model relates to the technical field of pipeline leakage detection tools, and in particular to a water supply pipeline leakage detector. Background Technology

[0002] Pipeline network usually refers to urban water supply pipelines, which are complex pipeline systems. They are generally composed of water treatment systems, transmission pipelines, water tanks, pumping stations, and user terminals. Pipeline network leakage detection devices are devices that detect leakage points in urban water supply pipelines. Common types include sound detection pipeline network leakage detection devices and pressure change detection pipeline network leakage detection devices.

[0003] A pipeline leakage detection device, disclosed on January 24, 2025 (publication number CN222392705U), includes a base frame, a servo motor, a display and control mechanism, a detection probe, and a dual-head servo motor. A bracket is fixedly connected to the middle of the upper surface of the base frame, and a servo motor is fixedly mounted on the upper surface of the base frame along the side of the bracket. The display and control mechanism is fixedly installed at the upper end of the bracket. A positioning frame is fixedly connected to the end face of the base, and a detection probe is fixedly mounted at the lower end of the positioning frame. A dual-head servo motor is fixedly mounted in the middle of the upper inner wall of the base frame, and transmission rods are fixed to both ends of the output shaft of the dual-head servo motor. An adjustment structure is installed on the outer wall of the transmission rods. Support rods are installed at the four corners of the lower surface of the transmission plate, and square sleeves are fixedly installed at the lower ends of the support rods. This pipeline leakage detection device allows for easy adjustment of the chassis height, facilitating movement of the device on rough terrain.

[0004] However, the above-mentioned detection device still has some shortcomings in use. When a leak is detected in the underground pipeline, it is usually marked by manual assistance by spraying paint on the ground. However, in actual operation, the staff needs to stop the detection vehicle when spraying paint, and can only push it to detect again after the paint is finished. The detection efficiency needs to be further improved. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a water supply network leakage detector.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A water supply network leakage detector includes a wheeled detection vehicle, on which a display screen and a controller are connected, and a probe is fixedly connected to the side wall of the detection vehicle. It also includes: The symmetrically arranged marking cylinders are fixedly connected to the inspection vehicle; The marking tube is fixedly connected to the inspection vehicle, and the marking tube is connected to the marking cylinder; A drive cylinder is fixedly connected to the testing vehicle. A first air supply pipe is fixedly connected to the side wall of the drive cylinder. The end of the first air supply pipe away from the drive cylinder is connected to the marking cylinder.

[0007] Preferably, an impact bladder is fixedly connected to the marking cylinder, and a second air supply pipe is fixedly connected to the marking cylinder. One end of the second air supply pipe is connected to the impact bladder, and the other end of the second air supply pipe is connected to the drive cylinder.

[0008] Furthermore, a first pressure relief pipe is fixedly connected to the impact bladder.

[0009] Preferably, a drive rod is slidably connected to the drive cylinder, and a slide plug is slidably connected inside the drive cylinder, with the drive rod and the slide plug being fixedly connected.

[0010] Furthermore, a rotating rod is rotatably connected to the testing vehicle, the rotating rod is fixedly connected to the wheel, and a cam is fixedly connected to the rotating rod, the cam abutting against the drive rod.

[0011] Furthermore, a compression wheel is rotatably connected to the end of the drive rod away from the slide, and the cam abuts against the compression wheel.

[0012] Furthermore, a spring is fixedly connected to the slide, and the end of the spring away from the slide is fixedly connected to the inner wall of the drive cylinder.

[0013] Furthermore, a second pressure relief pipe is fixedly connected to the top of the marking cylinder, and the second pressure relief pipe is connected to the marking cylinder.

[0014] Compared with the prior art, this utility model provides a water supply network leakage detector, which has the following beneficial effects: The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model uses the rotation of a wheel to drive the rotating rod and cam to rotate, which in turn causes the drive rod and the sliding plug to compress gas. The gas is then blown into the marking cylinder through the first and second air supply pipes to disturb the coating and to inflate the impact bladder to impact the coating. When the sliding plug resets, the pressure relief pipe of the impact bladder releases air and agitates the coating again. The multi-stage coordinated disturbance of the coating in the marking cylinder effectively prevents the marking coating from separating and ensures the clarity of the marking effect. Furthermore, marking with this device eliminates the need for manual auxiliary marking, thus improving detection efficiency. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1: Reference Figures 1-7 A water supply network leakage detector includes a detection vehicle 1 with wheels 2, a display screen 101 and a controller 102 connected to the detection vehicle 1, and a probe 103 fixedly connected to the side wall of the detection vehicle 1. It also includes: The symmetrically arranged marking cylinders 3 are fixedly connected to the inspection vehicle 1; The marking tube 301 is fixedly connected to the inspection vehicle 1, and the marking tube 301 is connected to the marking cylinder 3; The drive cylinder 4 is fixedly connected to the inspection vehicle 1. A first air supply pipe 302 is fixedly connected to the side wall of the drive cylinder 4. The end of the first air supply pipe 302 away from the drive cylinder 4 is connected to the marking cylinder 3.

[0019] An impact bladder 5 is fixedly connected to the marking cylinder 3, and a second air supply pipe 303 is fixedly connected to the marking cylinder 3. One end of the second air supply pipe 303 is connected to the impact bladder 5, and the other end of the second air supply pipe 303 is connected to the drive cylinder 4.

[0020] The first pressure relief pipe 501 is fixedly connected to the impact bladder 5.

[0021] Reference Figure 7 In practice, the first pressure relief pipe 501 is equipped with a commercially available electromagnetic pressure relief valve.

[0022] Reference Figure 6 An air supply pipe 404 is fixedly connected to the drive cylinder 4, and one-way valves are provided on the air supply pipe 404, the first air supply pipe 302, and the second air supply pipe 303.

[0023] A drive rod 402 is slidably connected to the drive cylinder 4, and a slide plug 401 is slidably connected inside the drive cylinder 4. The drive rod 402 and the slide plug 401 are fixedly connected.

[0024] A rotating rod 201 is rotatably connected to the inspection vehicle 1. The rotating rod 201 is fixedly connected to the wheel 2. A cam 2011 is fixedly connected to the rotating rod 201. The cam 2011 abuts against the drive rod 402.

[0025] Reference Figure 1 , Figure 5 During the testing process, staff members push the testing vehicle 1 to move, which in turn moves the probe head 103 to conduct the detection. Reference Figure 1 , Figure 3 and Figure 5 When a leak is detected in an underground pipe, the controller 102 will open the electromagnetic control valve on the marking pipe 301. At this time, the marking paint in the marking cylinder 3 will leak out, thus completing the marking on the ground. Reference Figures 1-7 During the testing process, the movement of wheel 2 will drive the rotating rod 201 to rotate synchronously. The rotation of rotating rod 201 will drive the cam 2011 to rotate synchronously. When the cam 2011 rotates, the cam 2011 will squeeze and push the drive rod 402 to slide. The sliding of the drive rod 402 will push the sliding plug 401 to slide and squeeze the gas in the drive cylinder 4. After the gas is squeezed, it will be discharged through the first gas supply pipe 302 and the second gas supply pipe 303. Reference Figure 7 The outlet end of the first gas supply pipe 302 is inclined, and the included angle between the outlet end of the first gas supply pipe 302 and the inner wall of the marking cylinder 3 is 30°.

[0026] Reference Figure 4 , Figure 7 The gas delivered through the first gas supply pipe 302 will be blown into the marking cylinder 3. At this time, the blown gas will disturb the marking paint in the marking cylinder 3. By disturbing the marking paint, the paint can be effectively prevented from separating, thereby ensuring the subsequent marking effect.

[0027] Reference Figure 4 , Figure 7The gas delivered through the second gas pipe 303 will be blown into the impact bladder 5. The impact bladder 5 will inflate and bulge. At this time, the inflated impact bladder 5 will impact and disturb the material in the marking cylinder 3, thereby further agitating the marking paint in the cylinder and further preventing the paint from separating.

[0028] Reference Figure 7 When the sliding plug 401 is reset, the first pressure relief pipe 501 on the impact bladder 5 will open simultaneously. At this time, the gas in the impact bladder 5 will be discharged through the first pressure relief pipe 501. The discharged gas will once again impact and agitate the marking paint in the marking cylinder 3, thereby further preventing the paint from separating.

[0029] It should be noted that the impact bladder 5 is an elastic bladder that is available for purchase on the market.

[0030] A compression wheel 4021 is rotatably connected to the end of the drive rod 402 away from the slide plug 401, and the cam 2011 abuts against the compression wheel 4021.

[0031] Reference Figure 4 , Figure 5 With the compression wheel 4021 in place, when the cam 2011 pushes the drive rod 402, it can stably compress and push to make the drive rod 402 slide.

[0032] A spring 403 is fixedly connected to the slide plug 401, and the end of the spring 403 away from the slide plug 401 is fixedly connected to the inner wall of the drive cylinder 4.

[0033] Reference Figure 6 The spring 403 provided on the slider 401 enables the slider 401 to be quickly reset.

[0034] A second pressure relief pipe 304 is fixedly connected to the top of the marking cylinder 3, and the second pressure relief pipe 304 is connected to the marking cylinder 3.

[0035] Reference Figure 6 In practice, the second pressure relief pipe 304 is equipped with a pressure relief valve that is available on the market.

[0036] Reference Figure 6 In practice, through the second pressure relief pipe 304 set at the top of the marking cylinder 3, as the gas in the impact bladder 5 is continuously discharged into the marking cylinder 3, the gas pressure in the marking cylinder 3 will increase. When the gas pressure in the marking cylinder 3 is too high and reaches the threshold of the pressure valve on the second pressure relief pipe 304, the second pressure relief pipe 304 will open, and the marking cylinder 3 will be depressurized, thereby preventing the marking cylinder 3 from exploding due to excessive gas pressure.

[0037] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
