It primarily includes water transmission channels, distribution networks, booster pump stations, water towers, reservoirs, and ancillary facilities. Water supply pipes can leak over time, and locating devices are essential for detecting leaks.

[0003] For example, patent application number CN202222895165.2 discloses a pipeline leak detector, comprising a housing, a retractable drive wheel, two annular airbags, and an air pump. The two annular airbags are located at either end of the housing, a multi-way solenoid valve is provided within the housing, and an air inlet is provided on the housing's peripheral wall. The air pump is connected to the annular airbags and the air inlet, respectively, via the multi-way solenoid valve and a hose. An air pressure sensor is provided on the housing's outer wall. The annular airbags are inflated by the air pump, expanding and contacting the inner wall of the pipe on both sides of the joint, forming a sealed space between the annular airbags, the housing's outer wall, and the inner wall of the pipe. The air pump then inflates the sealed space, and the air pressure in the sealed space is detected by the air pressure sensor. However, since the air pump increases the air pressure in the pipe when pressurized, the air pressure exerts a reverse thrust on the housing, making it easy for the annular airbags in the pipe to become loose, thereby affecting the detector's positioning stability and safety in use.

DETAILED DESCRIPTION

[0021] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] according to Figure 1 、 2 As shown in Figures 3 and 4, this embodiment provides a water supply network leakage locating device, comprising a fixing base 1, a positioning tube 2, and a detection tube 4. The fixing base 1 and the detection tube 4 are fixedly connected at the left and right ends. The detection tube 4 is provided with a pressurizing port 5 and a pressure sensor 6 at the end away from the fixing base 1. An airbag is provided on the outside of the positioning tube 2 for sealing.

[0023] A plurality of bolt positioning members are provided around the fixing base 1, and the bolt positioning members are fixedly connected to the fixing base 1;

[0024] Place the fixing seat 1 outside the pipe mouth of the pipeline to be tested, extend the positioning tube 2 and the detection tube 4 into the pipeline, and the bolt positioning parts around the fixing seat 1 fix the pipeline from the outside of the pipeline. The airbag part expands from the pipeline to ensure the sealing of the pipeline. The boosting port 5 increases the pressure in the pipeline, and the pressure sensor 6 is used to detect whether there is any leakage in the closed pipe section.

[0025] A positioning plate 12 is provided at the upper end of the fixing seat 1, and a group of clamping members are provided at each end of the positioning plate 12. The two groups of clamping members are evenly arranged in the circumferential direction of the axis of the fixing seat 1, and an adjusting member is provided on the positioning plate 12 for simultaneously controlling the tightness of the two groups of clamping members.

[0026] To prevent the detection tube 4 from loosening during pressurization, the clamps at both ends of the positioning plate 12 will be stuck on the edge of the pipe, and the adjustment part controls the two sets of clamps to clamp at the same time, reinforcing the detection tube 4 from the edge of the pipe to ensure the safe use of the positioning device.

[0027] About airbag parts:

[0028] The airbag assembly includes at least one sealing airbag 3, which is fixedly connected to the outside of the positioning cylinder 2. A second conduit 11 is provided on the outside of the fixing base 1 and communicates with the sealing airbag 3. The end of the second conduit 11 away from the fixing base 1 is connected to a second air pump 10. The valve between the second air pump 10 and the second conduit 11 is opened, and the second air pump 10 increases the pressure of the sealing airbag 3 through the second conduit 11. After the sealing airbag 3 expands, it adheres to the inner wall of the pipe, ensuring a seal between the detection tube 4 and the pipe. It should be noted that before using the sealing airbag 3, the inner wall of the pipe opening area needs to be cleaned in advance.

[0029] Regarding the pressurization inside the pipeline, specifically, a first conduit 9 is provided on the outside of the fixing base 1 and communicates with the pressurization port 5. The end of the first conduit 9 away from the fixing base 1 is connected to a first air pump 8. To test for leaks in the corresponding pipeline, the valve connecting the first air pump 8 and the first conduit 9 is opened. The first air pump 8 increases the pressure in the closed pipe section through the first conduit 9 and the pressurization port 5. The pressure change in the pipe section is measured by the pressure sensor 6 to determine whether the closed pipe section needs to be replaced.

[0030] For the specific structure of the clamping parts, please refer to the following description:

[0031] The clamping member includes two mating blocks 17, with an arc-shaped clamping plate 19 fixedly connected to the lower end of the mating block 17. The upper end of the mating block 17 is slidably connected to a slide groove provided on the lower end surface of the positioning plate 12. The two clamping members are located at the left and right ends of the positioning plate 12. Each clamping member includes two mating blocks 17. To secure the detection tube 4, the edge of the enclosed tube is placed between the two mating blocks 17.

[0032] About the adjustment parts:

[0033] The adjustment member includes a double-ended screw 16, which is rotatably connected to the chute. The outer side of the mating block 17 has two threads, one in each direction, which are respectively threadedly connected to the two mating blocks 17. The outer side of the positioning plate 12 is rotatably connected to an adjustment knob 18, which is fixedly connected to the double-ended screw 16. The two double-ended screws 16 are fixedly connected by a connecting shaft. When the adjustment knob 18 is turned, the two double-ended screws 16 rotate simultaneously. During the rotation of the double-ended screw 16, the double-ended screw 16 engages with the mating block 17, and the mating block 17 moves along the shaft of the double-ended screw 16. Due to the different rotation directions of the threads on the outer side of the mating block 17, when the double-ended screw 16 rotates, the two mating blocks 17 in the chute will move in opposite directions along the chute.

[0034] About bolt locators:

[0035] The bolt locator includes a bolt seat 14, which is fixedly connected to the outside of the fixing base 1. A fixing bolt 15 is provided at the end of the bolt seat 14 away from the fixing base 1 and is threadedly connected to the bolt seat 14. The fixing bolt 15 is arranged opposite the axis of the fixing base 1. After the detection tube 4 is fixed in the center of the pipeline by the clamp, the fixing bolt 15 is screwed into the pipeline. The fixing bolt 15 contacts the outer wall of the pipeline, securing the fixing base 1 and the detection tube 4 from the outside of the pipeline.

[0036] In order to facilitate the staff to hold the positioning device, in a preferred solution, a handle 13 is provided on the side of the positioning plate 12 away from the fixing seat 1 , and the handle 13 is fixedly connected to the positioning plate 12 .

[0037] How this application works:

[0038] The fixing base 1 is placed outside the mouth of the pipe to be inspected. The positioning tube 2 and detection tube 4 are extended into the pipe. The bolt positioning members surrounding the fixing base 1 secure the pipe from the outside. The airbag expands from the pipe to ensure the pipe is sealed. The pressurization port 5 increases the pressure in the pipe, and the pressure sensor 6 detects whether the pipe section has leaks. To prevent the detection tube 4 from loosening during pressurization, the clamps at both ends of the positioning plate 12 are locked to the edge of the pipe. The adjustment member controls the two sets of clamps to clamp simultaneously, providing secondary reinforcement to the detection tube 4 from the edge of the pipe, ensuring the safe use of the leak locating device.
