Description

Technical Field

[0001] This utility model relates to the field of underground pipeline leakage detection technology, and in particular to a device for accurately locating leakage points in underground pipelines. Background Technology

[0002] Underground pipelines are pipes laid underground to transport liquids, gases or loose solids. After long-term use, pipelines are prone to leakage problems when transporting liquids. In order to easily find the leak in underground pipelines, leakage point location equipment is needed. Leakage point location equipment usually includes sensors, main unit, connecting wires and earpieces.

[0003] Most existing underground pipeline leak location devices require the use of sensors to detect underground sounds, which are then processed by a main unit and transmitted to headphones for inspection personnel. However, the inventors have found that because inspectors need to constantly monitor changes in the sound, it is not convenient to mark the detected leak areas in a timely manner, which can easily lead to omissions. Therefore, we propose a precise device for monitoring and locating leaks in underground pipelines. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a device for accurately locating leaks in underground pipelines, so as to solve the current technical problem that the current method of testing personnel need to pay attention to changes in sound at all times, which makes it inconvenient to mark the leaking area in a timely manner and easily leads to omissions.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A device for accurately locating leaks in underground pipelines includes a mobile platform and a positioning sensor. The mobile platform consists of a mobile base, a support column, a pusher, and a top plate. A fixed frame is fixedly installed on the top of the mobile base. The fixed frame is equipped with an adjustment structure for adjusting the position of the positioning sensor. A marking mechanism is installed on the mobile platform.

[0008] The marking mechanism includes a pump body that is controlled to start and stop by a remote controller. A nozzle is installed at the output end of the pump body through a discharge channel. A dye box is installed on the top of the top plate. A feed pipe is provided between the dye box and the pump body. The end of the feed pipe away from the pump body passes through the dye box and extends to the bottom wall of the inner cavity of the dye box.

[0009] As an improved technical solution, the movable base is provided with a cylindrical groove, and the inner wall of the cylindrical groove is provided with multiple limiting grooves;

[0010] The adjustment structure includes a hydraulic push rod installed on the inner top wall of the fixed frame. A fixed plate corresponding to the cylindrical groove is installed on the piston end of the hydraulic push rod, and the fixed plate is adapted to the cylindrical groove. The positioning sensor is installed on the bottom of the fixed plate. Limiting strips corresponding to the limiting grooves are installed on the fixed plate, and the limiting strips are adapted to the limiting grooves. The fixed plate is slidably installed in the cylindrical groove through the limiting strips and the limiting grooves.

[0011] As an improved technical solution, multiple limiting grooves are equidistantly arranged along the axial / circumferential direction of the cylindrical groove.

[0012] As an improved technical solution, the discharge channel consists of a hollow disc installed on the top plate and a discharge pipe installed at the bottom of the hollow disc and connected to it. The pump body is installed on the hollow disc, and the nozzle is installed on the end of the discharge pipe away from the hollow disc.

[0013] As an improved technical solution, both the movable base and the top plate are provided with through holes for inserting the discharge pipe, and the discharge pipe is sleeved and installed in the through holes.

[0014] As an improved technical solution, the dye box is equipped with a feed inlet for dispensing dye, and the feed inlet is connected to the dye box.

[0015] As an improved technical solution, the positioning sensor is connected to an external host via a connecting wire, and the external host is connected to an external headset. The bottom of the positioning sensor is provided with a rubber pad to reduce the pressure between the positioning sensor and the ground.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are:

[0017] 1. This utility model uses a remote control to start the pump body. At this time, the input end of the pump body draws the dye in the dye box into the pump body through the inner cavity of the feed pipe, and then discharges it from the output end of the pump body. The dye passes through the inner cavity of the hollow disc, the discharge pipe and the inner cavity of the nozzle, and is finally sprayed onto the ground through the nozzle to form a mark, which makes it convenient to mark the ground area in a timely manner and thus avoids the phenomenon of omission.

[0018] 2. This utility model allows for the electrical connection of the positioning sensor to an external host via a connecting wire, and the connection of an external headset to the external host. The inspector then wears the external headset, turns on the external host, and activates the hydraulic push rod fixed to the mounting bracket. The piston end of the hydraulic push rod moves the mounting plate, which in turn moves the positioning sensor closer to the ground until the sensor is properly aligned and in contact with the ground for inspection. During this process, the limiting strip moves along the inner cavity of the limiting groove to provide a limiting and guiding function, ensuring the stability of the positioning sensor during movement. The moving platform acts as a moving device, facilitating pipeline inspection. Attached Figure Description

[0032] Reference Figures 1-3The movable base 1 has a cylindrical groove 101, and the inner wall of the cylindrical groove 101 has multiple limiting grooves 102.

[0033] The adjustment structure includes a hydraulic push rod 6 installed on the inner top wall of the fixed frame 5. A fixed plate 7 corresponding to the cylindrical groove 101 is installed on the piston end of the hydraulic push rod 6, and the fixed plate 7 is adapted to the cylindrical groove 101. The positioning sensor 9 is installed at the bottom of the fixed plate 7.

The fixed plate 7 is slidably installed in the cylindrical groove 101 through the limiting strip 8 and the limiting groove 102 to facilitate the adjustment of the position of the positioning sensor 9 and ensure the stability of the positioning sensor 9 during movement.

[0034] Reference Figure 2 Multiple limiting grooves 102 are equidistantly arranged along the axial / circumferential direction of the cylindrical groove 101 to facilitate adaptation to the limiting strip 8.

[0035] Reference Figure 1 and Figure 4 The discharge channel consists of a hollow disc 10 installed on the top plate 4 and a discharge pipe 14 installed at the bottom of the hollow disc 10 and connected to it. The pump body 11 is installed on the hollow disc 10, and the nozzle 15 is installed on the end of the discharge pipe 14 away from the hollow disc 10, so that the dye can pass through the inner cavity of the hollow disc 10, the discharge pipe 14 and the inner cavity of the nozzle 15, and finally be sprayed onto the ground through the nozzle 15 to form a mark.

[0036] Reference Figure 1 and Figure 2 Both the movable base 1 and the top plate 4 are provided with through holes 103 for inserting the discharge pipe 14, and the discharge pipe 14 is sleeved and installed in the through holes 103 to facilitate the installation of the discharge pipe 14.

Then, the inspector wears the external earphone, turns on the external host, and starts the hydraulic push rod 6 fixed on the mounting bracket 5. At this time, the piston end of the hydraulic push rod 6 drives the fixed plate 7 to move, and the fixed plate 7 drives the positioning sensor 9 to move towards the ground until the positioning sensor 9 is adjusted. At this time, the positioning sensor 9 is in contact with the ground for detection. During this period, the limiting strip 8 moves along the inner cavity of the limiting groove 102 to play a limiting and guiding role, while ensuring the stability of the positioning sensor 9 during movement. The moving platform plays the role of a moving device, thereby facilitating the inspection of the pipeline.

[0040] When a leak is detected, the pump body 11 is started via remote control. At this time, the input end of the pump body 11 draws the dye from the dye box 13 into the pump body 11 through the inner cavity of the feed pipe 12, and then discharges it from the output end of the pump body 11. The dye passes through the inner cavity of the hollow disc 10, the discharge pipe 14, and the inner cavity of the nozzle 15, and is finally sprayed onto the ground through the nozzle 15 to form a mark. This facilitates timely marking of the ground area and avoids omissions. This device not only facilitates timely marking of the ground area, but also prevents omissions.
