[0002] Underground pipeline detection is a prerequisite for the construction and maintenance of urban infrastructure. Current operations typically involve three people: one operates the detector, one clears debris from the ground, and one marks the pipeline with paint or coating. This process has the following shortcomings:

[0003] Multiple divisions of labor lead to low efficiency and high labor costs;

[0004] If paint / coating markings are sprayed incorrectly, they need to be removed with chemical solvents or by sanding, which is labor-intensive and can easily leave marks.

[0005] The mixing of residual markings with old and new markings can easily lead construction workers to misjudge the pipeline route, causing digging accidents.

[0006] The fixed probe angle makes it difficult to adapt to the detection needs of pipelines at different depths and inclination angles.

[0007] Therefore, there is an urgent need for an integrated probe device that combines "multi-angle detection + rapid and removable marking". Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0027] Please see Figures 1-6 This utility model provides a technical solution: an adjustable probe device for multi-angle detection of underground pipelines, including a signal processor 1. A marking mechanism 4 is fixedly connected to the outer side of the lower end of the signal processor 1. The marking mechanism 4 includes a mounting bracket 41. A cleaning air cylinder 42 is fixedly connected to the inner side of one cylindrical end of the mounting bracket 41. A storage container 43 is fixedly connected to the upper end of the cleaning air cylinder 42. A compression spring 44 is fixedly connected to the inner side of the cleaning air cylinder 42. A piston 45 is fixedly connected to the lower end of the compression spring 44. A discharge pipe 46 is fixedly connected to the lower end of the piston 45. An anti-wear washer 47 is fixedly connected to the lower end of the discharge pipe 46. A connecting air pipe 48 is opened inside the cleaning air cylinder 42. A material taking device 49 is fixedly connected to the upper end of the piston 45. The outer side of the piston 45 is slidably connected to the inner wall of the cleaning air cylinder 42. The material taking device 49 includes a material taking pipe 491. A sealing ring 492 is fixedly connected to the outer side of the lower end of the material taking pipe 491. A material taking hole 493 is opened at the upper end of the sealing ring 492.

[0028] In some specific embodiments, a receiving plate 2 is fixedly connected to the lower end of the signal processor 1, and an adjustable probe 3 is rotatably connected to the lower end of the receiving plate 2. The lower end of the marking mechanism 4 is located 5cm below the adjustable probe 3. The mounting bracket 41 is fixedly connected to the outer side of the lower end of the signal processor 1 by bolts. This detachable connection method facilitates the maintenance of the marking mechanism 4, replacement of parts, or adjustment of its position, thereby improving the maintainability of the equipment.

[0029] In some specific embodiments, the vertical cross-section of the storage container 43 is trapezoidal, the axis of the storage container 43 coincides with the axis of the cleaning air cylinder 42, the outer diameter of the storage container 43 is 1.2 times the outer diameter of the cleaning air cylinder 42, the mounting bracket 41 is fixedly connected to the lower outer side of the signal processor 1 by bolts, and the shape of being wider at the top and narrower at the bottom is conducive to the smooth flow of the marking material to the bottom under the action of gravity, which is convenient for the material picking device 49 to pick up the material and reduces the possibility of the marking material remaining in the container.

[0030] In some specific embodiments, the compression spring 44 is vertically arranged inside the cleaning cylinder 42. The upper end of the compression spring 44 is fixedly connected to the top of the inner wall of the cleaning cylinder 42, and the lower end of the compression spring 44 is fixedly connected to the upper end face of the piston 45. The compression spring 44 is located on the central axis of the cleaning cylinder 42. The vertical section of the storage container 43 is trapezoidal. The vertical arrangement of the compression spring 44 ensures that the direction of the force remains vertical during the compression and rebound process, which can accurately push the piston 45 to move up and down, thus ensuring the stability of the air compression and marking material picking process inside the cleaning cylinder 42.

[0031] In some specific embodiments, the discharge pipe 46 is a hollow cylindrical structure, the axis of the discharge pipe 46 coincides with the axis of the cleaning air cylinder 42, the piston 45 has a hollow structure on the inner side, the upper end of the discharge pipe 46 communicates with the hollow structure on the inner side of the piston 45, and the outer side of the piston 45 is in close contact with the inner wall of the cleaning air cylinder 42. The discharge pipe 46 is a hollow cylindrical structure, which can provide a smooth and unobstructed channel, allowing the marking material to fall smoothly from the hollow structure on the inner side of the piston 45 to the ground, reducing the possibility of material blockage.

[0032] In some specific embodiments, multiple connecting air pipes 48 are provided, and the connecting air pipes 48 are arranged in a circular array with the axis of the cleaning air cylinder 42 as the axis. The lower end of the connecting air pipe 48 is connected to the outside of the cleaning air cylinder 42. The shape of the vertical cross section of the lower end of the connecting air pipe 48 is trapezoidal, so that compressed air can be ejected from multiple directions, forming a relatively uniform airflow below the cleaning air cylinder 42, which can more effectively blow away the debris on the ground and improve the effect of ground cleaning.

[0033] In some specific embodiments, the outer side of the sealing ring 492 is tightly attached to the inner wall of the cleaning air cylinder 42, the upper end of the material taking tube 491 is located at the bottom of the storage container 43, and the material taking holes 493 are symmetrically arranged on the outer side of the upper end of the material taking tube 491. The cross-sectional shape of the material taking holes 493 is fan-shaped. The inner side of the material taking tube 491 and the material taking holes 493 are connected to the inner side of the piston 45. This design increases the area of ​​the material taking holes 493, allowing the marking material to enter the material taking tube 491 more quickly and evenly, thus improving the material taking efficiency. The outer side of the sealing ring 492 is tightly attached to the inner wall of the cleaning air cylinder 42 to prevent the marking material from leaking to other parts of the cleaning air cylinder 42 during the material taking process, ensuring the sealing and accuracy of the material taking process.

[0034] The working method of this utility model:

[0035] First, add sufficient marking material to the storage container 43. The operator pushes or moves the entire device to the area to be detected. By rotating the adjustable probe 3 at the lower end of the receiving plate 2, it is adjusted to a suitable detection angle to achieve multi-angle detection of underground pipelines. The signal processor 1 is turned on. The signal processor 1 controls the adjustable probe 3 to emit detection signals and receives signals reflected back from the underground pipelines. The signal processor 1 processes and analyzes the received signals to preliminarily determine the location, depth, and other information of the underground pipelines. Before marking, it is necessary to clean up the debris on the ground. At this time, the anti-wear washer 47 of the discharge pipe 46 is placed on the ground. Then, the cleaning air cylinder 42 is controlled to move downward. At the same time, the piston 45 is forced to move upward and compress the squeeze spring 44. The movement of the piston 45 compresses the air inside the cleaning air cylinder 42 to the inside of the connecting air pipe 48. The compressed air is sprayed out from the lower end of multiple connecting air pipes 48, forming an airflow below the cleaning air cylinder 42 to blow away the debris on the ground.

[0036] As the piston 45 moves upward, it will drive the material taking tube 491 to move upward. The material taking hole 493 at the upper end of the material taking tube 491 will move to the inside of the storage container 43. The marking material inside the storage container 43 will enter the hollow structure inside the piston 45 through the material taking hole 493 and the material taking tube 491, and then fall to the ground from the inside of the discharge tube 46. When the compression spring 44 drives the piston 45 and the discharge tube 46 to return to their original positions, the material taking hole 493 will move down to the inside of the cleaning cylinder 42, waiting for the next material marking.

[0037] By adopting the above-disclosed technical solution of this utility model, the following beneficial effects are obtained:

[0038] Structural integration: The "ground cleaning-quantitative material collection-marking" process is integrated into the same piston-cylinder mechanism, which can be completed in one go with one hand, reducing manual labor by 2 / 3;

[0039] Easy-to-remove markings: Made with dry powder / granular marking materials, with no solvent adhering. Incorrect markings can be directly broken up by stepping on them or blown away by the next airflow, leaving no residue on the ground.

[0040] Avoid misjudgment: Each marking color / material can be changed, with no historical traces interfering, ensuring that the construction basis is unique and accurate;

[0041] Angle adjustable: The adjustable probe (3) can continuously rotate at ±90° pitch and 360° horizontally, adapting to the detection of branches, intersections, and deeply buried pipelines;

[0042] Easy to maintain: The marking mechanism (4) is connected to the signal processor (1) by bolts, and can be quickly removed for cleaning or replacement of consumables;

[0043] Green and environmentally friendly: No paint volatilization, reducing VOC emissions, and meeting urban environmental protection construction requirements.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
