Description

Technical Field

[0001] This utility model relates to the field of ecological and environmental protection technology, and in particular to a pipeline connectivity tracing and identification device. Background Technology

[0002] Currently, tracing and investigating municipal pipe networks is crucial for identifying points of cross-connection and ensuring water quality. However, during these investigations, discrepancies often arise between pipe network connections and existing site maps, or the maps may be missing information about specific sections of the network. By identifying the locations of these cross-connections and their connections to stormwater pipes, targeted rectification can be implemented, thus addressing the root cause of sewage entering rivers and threatening water quality.

[0003] Currently, the mainstream methods used in pipeline network tracing and investigation in China include: CCTV pipeline robot detection, which involves using a pipeline robot equipped with a camera system to enter the pipe and capture images, while manual identification of pipeline interfaces, flow direction markers, and abnormal water outlets; fluorescent / chemical tracer method, which involves releasing fluorescent dyes or salt tracers at suspected upstream nodes, sampling and testing at multiple downstream points, and determining the connectivity path by color development or concentration changes; and manual well knocking analysis method, which relies on experienced technicians to open and verify wells one by one, and infer connectivity through experience-based methods such as water flow sound identification, observation of scum flow direction, and measurement with a simple flow meter.

[0004] However, CCTV requires investment in specialized robots and high-definition cameras, with equipment rental and labor costs exceeding 10,000 yuan per kilometer per inspection. It also suffers from slow travel speeds and cannot operate in high-water-level or silted-up pipe sections, making it prone to missed detections in turbid water, full-pipe flow, or when the diameter of concealed branch pipes is small. The tracer method involves reagent procurement, multi-point deployment, and laboratory analysis, resulting in even higher overall costs. Furthermore, it requires waiting for diffusion and multiple sampling, with single-path verification taking hours to days. Well-knocking analysis is limited by well spacing and human experience, resulting in a short daily inspection distance. It is also affected by environmental noise and water turbulence, leading to a high rate of subjective misjudgment. All of the above-mentioned existing source tracing and investigation methods suffer from high operating costs, low efficiency, and low accuracy. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] Figure 1 This is a three-dimensional structural diagram of a pipeline connectivity tracing and identification device proposed in this utility model; Figure 2 This is a schematic diagram of the limiting component structure of a pipeline connectivity tracing and discrimination device proposed in this utility model; Figure 3 This is a schematic diagram of the placement structure of a pipeline connectivity tracing and identification device proposed in this utility model; Figure 4 This is a schematic diagram of the internal structure of the placement part of a pipeline connectivity tracing and discrimination device proposed in this utility model; Figure 5 This is a schematic diagram of the first battery location structure of a pipeline connectivity tracing and discrimination device proposed in this utility model; Figure 6 This is a schematic diagram of the internal plan of a pole component of a pipeline connectivity tracing and identification device proposed in this utility model.

Figures 1 to 8 As shown, this utility model embodiment provides a pipeline connectivity tracing and identification device, including a rod 1. An electric actuator 8 is vertically connected to the outer surface of one end of the rod 1. The telescopic end of the electric actuator 8 is connected to a mounting block 9. A placement part 10 is fixedly installed on one side of the mounting block 9 by a fixing rod 14. The interior of the placement part 10 has a cavity for placing smoke sheets. A smoke outlet 15 is provided through the top surface of the placement part 10. A blower 16 is installed on the top of the mounting block 9. An electronic igniter 21 is provided inside the placement part 10. A control panel 6 is installed on the other end of the rod 1. The electric actuator 8, the blower 16, and the electronic igniter 21 are communicatively connected to the control panel 6.

[0022] In this embodiment of the invention, the electric actuator 8, blower 16, and electronic igniter 21 are all communication-connected to the control panel 6. Operators can control the operation of each component via buttons on the control panel 6. When using the equipment, the operator stands beside the manhole, holds the rod 1 with both hands, and inserts the end of the rod 1 equipped with the electric actuator 8 into the manhole. By operating the control panel 6, the electric actuator 8 extends into the pipe network opening to be inspected, pushing the mounting block 9 and placement part 10 into the opening. Then, the electronic igniter 21 is controlled to ignite the smoke sheet in the placement part 10, and the smoke diffuses outward through the smoke outlet 15. Simultaneously, the blower 16 is turned on, blowing air into the pipe network. The smoke flows into the pipe network with the airflow. Inspectors can open the downstream manhole cover to be inspected and use the smoke to determine whether it is connected to the upstream manhole network where the equipment is located. This equipment requires only one person to operate at the inlet of the pipeline to be investigated. It is simple to use and requires no complicated procedures. Investigators downstream use wind-driven smoke to determine connectivity, reducing subjective errors and ensuring investigation efficiency. This effectively overcomes the problems of high operating costs, low efficiency, and low accuracy associated with traditional techniques.

[0023] For example, in this embodiment of the invention, the rod 1 can be a traditional nested pipe body. Its length can be adjusted by stretching the embedded end connected to the electric actuator 8 to adapt to wells of different depths. An external clamp is used to secure the embedded end to the socket end where the control panel 6 is installed, thus maintaining a stable length. In other possible implementations, the rod 1 can also employ an electrically controlled telescopic structure such as an electric actuator.

[0024] Optionally, a limiting component is provided at the other end of the rod, including a fixed plate 3, a limiting plate 5, and a top plate 51 arranged sequentially at intervals along the axial direction of the rod 1. One side of the fixed plate 3 is connected to one end of the rod 1, and the other side is connected to the top plate 51 via a vertical rod 4. The limiting plate 5 is sleeved on the vertical rod 4. Exemplarily, in this embodiment of the present invention, when the operator holds the rod 1, their hand not used for operating the control panel 6 can hold the vertical rod 4, which is provided with a fixed plate 3 and a limiting plate 5 at both ends, or the limiting plate 5 and the top plate 51 for limiting, ensuring the stability of the operator's grip. In the event of loss of grip, along the axial direction of the rod 1, the limiting plate 5 and the top plate 51 can collide and block the operator's hand or arm to prevent direct fall into the well, giving the operator time to react and regain a firm grip, thus improving safety and stability.

[0025] Optionally, the limiting plate 5 is slidably sleeved on the upright 4, and a threaded cylinder 11 perpendicular to the fixed plate 3 is rotatably connected to the other end face of the fixed plate 3. A threaded rod 12 coaxial with the threaded cylinder 11 is rotatably provided on the limiting plate 5, and the end of the threaded rod 12 away from the limiting plate 5 is threadedly engaged with the threaded cylinder 11. Exemplary, in this embodiment of the present invention, the user can rotate the two threaded cylinders 11 synchronously in the same direction, thereby causing the two threaded rods 12 to extend and retract inside the threaded cylinders 11. When the threaded rods 12 extend and retract, the limiting plate 5 can be pushed and pulled to slide on the outside of the upright 4. Thus, when the user holds the upright 4, the limiting plate 5 can be pushed and pulled to a position that contacts the user's hand, thereby limiting the user's hand, increasing the stability of the grip, and reducing the possibility of the rod 1 falling off due to accidental disengagement. The surface of the anti-slip sleeve 13 is provided with anti-slip texture, which makes it easier for the user to rotate the threaded cylinders 11. Similarly, the threads of the two threaded rods 12 and the threaded cylinders 11 used in this device can also be set in opposite directions, thereby allowing the user to move the two threaded cylinders 11 in opposite directions to control the movement of the limiting plate 5.

[0026] Optionally, refer to Figure 3 and Figure 4 A cover plate 17 is hinged to one side of the placement part 10, and a fixing block 18 is fixedly connected to the bottom surface of the cover plate 17. A fixing plate 20 is fixedly connected to the bottom surface of the placement part 10, and a screw 19 passes between the fixing plate 20 and the fixing block 18. Specifically, the cover plate 17 is hinged to one side of the placement part 10, and the opening of the side opening of the placement part 10 can be controlled by the deflection of the cover plate 17. When the cover plate 17 is opened, the user can easily place the smoke tablet inside the placement part 10 or replace it. After placement, the cover plate 17 can be closed. At this time, the screw holes on the surfaces of the fixing block 18 and the fixing plate 20 are on the same horizontal line. Then, the screw 19 passes through the screw holes on the surfaces of the fixing plate 20 and the fixing block 18 in sequence to fix the cover plate 17.

[0027] Optionally, refer to Figure 5 and Figure 6 The mounting block 9 contains a first battery 22 electrically connected to the blower 16. The rod 1 contains a second battery 23 electrically connected to the electric actuator 8 and a motor 2 driven by the electric actuator 8. Specifically, the first battery 22 is connected to the motor 2 via a wire, thus supplying power to the motor 2. The output end of the motor 2 is connected to the transmission mechanism inside the electric actuator 8, thereby providing power to the electric actuator 8 to ensure its stable extension and retraction. The first battery 22 is connected to the blower 16 via a wire, thus providing power to the blower 16 and ensuring its normal operation.

[0028] Optionally, a protective layer 7 is provided at the bottom of one end of the rod 1. Specifically, the protective layer 7 is made of a soft material. When the rod 1 is inserted into the interior of the pipe, the protective layer 7 can prevent the bottom wall of the pipe from contacting the rod 1 and causing damage to the workpiece.

[0029] Optionally, a sealing cover 24 is detachably connected to the bottom of the rod 1, and a protective layer 7 is disposed on the sealing cover 24. Furthermore, by providing a detachable sealing cover 24 at the bottom of the rod 1, operators can easily lift the bottom of the rod 1 to maintain and replace internal components such as batteries and motors, thereby further improving the overall service life.
