Description

Technical Field

[0001] The utility model relates to the technical field of municipal pipeline detection and positioning equipment, in particular to pipeline detection and positioning equipment. Background Art

[0002] Municipal pipelines are generally buried underground. To determine pipeline location and depth, appropriate detection methods are necessary. Existing pipeline detection and positioning methods typically rely on high-tech, high-cost equipment such as robots, metal pipeline detectors, and ultra-deep pipeline equipment. These devices are expensive to use and maintain, and are unable to address the problems of non-metallic and ultra-deep pipelines. Therefore, pipeline detection and positioning equipment has been designed to locate pipelines, reducing equipment costs and improving the accuracy of detection results. Utility Model Content

[0003] The purpose of the utility model is to provide a pipeline detection and positioning device, which bundles the cable on the hollow tube of the pipeline detection head, uses water pressure to provide propulsion for the pipeline detection head, so that the pipeline detection head can move to the end of the pipeline, further driving the cable to be distributed in the pipeline, making it convenient to use the pipeline detector to locate the cable and determine the position of the pipeline.

[0004] The utility model provides the following technical solution: a pipeline detection and positioning device, comprising a vehicle body, a mounting seat connected to the end of the vehicle body, symmetrically distributed bearing seats fixed on the mounting seat, a roller rotatably connected between the bearing seats, a hollow tube wound around the roller, one end of the hollow tube connected to a pipeline detection head, the other end of the hollow tube connected to the vehicle body, and the roller driven by a motor;

[0005] It also includes a cable rack, which is rotatably connected to a turntable, a cable wound on the turntable, one end of the cable connected to one end of the hollow tube, a water outlet hole is opened on the end of the pipeline detection head, and water flows into the hollow tube.

[0006] According to the above technical solution, a conical head is formed on one end face of the pipeline detection head, and a conical surface is formed on the other end face. The water outlet holes are evenly arranged on the conical surface, so that the water outlet direction is outward, resulting in the propulsion force being concentrated on the pipeline detection head, further improving the propulsion force.

[0007] According to the above technical solution, a cavity is opened in the pipeline detection head, the center of the cavity is connected to the hollow tube, and the cavity is also connected to the water outlet. The water is discharged from the water outlet through the cavity. The discharged water will generate a jet force to provide propulsion to the pipeline detection head.

[0008] According to the above technical solution, the hollow tube and the pipeline detection head are closely matched, and the connection strength between the hollow tube and the pipeline detection head is improved through the close match.

[0009] According to the above technical solution, a water tank is provided in the vehicle body, and the water tank is connected to the hollow pipe. The water tank provides water to the hollow pipe, further providing propulsion force for the pipeline detection head, so that the pipeline detection head moves smoothly in the pipeline.

[0010] Compared with the existing technology, the beneficial effect achieved by the utility model is: by connecting the cable to the hollow tube on the side of the pipeline detection head, the movement of the pipeline detection head is used to drive the cable to be extended, so that the cable is distributed in the pipeline, and then the cable is energized and the position of the cable is located using the pipeline detector, which can solve the detection problem of non-metallic pipelines and thus determine the position and burial depth of the pipeline.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example 1

[0018] See also Figure 1The utility model provides a technical solution: a pipeline detection and positioning device, comprising a vehicle body 1, a mounting seat 2 connected to the end of the vehicle body 1, symmetrically distributed bearing seats 3 fixed on the mounting seat 2, a roller 4 rotatably connected between the bearing seats 3, a hollow tube 41 wound around the roller 4, one end of the hollow tube 41 is connected to a pipeline detection head 6, and the other end of the hollow tube 41 is connected to the vehicle body 1, the roller 4 is driven by a motor, and the motor controls the rotation of the roller 4 so that the hollow tube 41 enters the pipeline 7 at a certain speed;

[0019] It also includes a cable rack 5, which is rotatably connected to a turntable 51, on which a cable 52 is wound. One end of the cable 52 is connected to one end of the hollow tube 41. A water outlet 63 is provided at the end of the pipeline detection head 6. Water is introduced into the hollow tube 41. The entry of the hollow tube 41 will also drive the cable 52 into the pipeline 7, causing the turntable 51 to rotate. After the pipeline detection head 6 is in place, the cable 52 is energized, and then the pipeline detector is used to detect and locate the energized cable 51, thereby determining the position of the pipeline and realizing detection and positioning of the pipeline.

[0020] like Figure 2 As shown, a conical head 61 is formed on one end surface of the pipeline detection head 6, and the conical head 61 can guide the pipeline detection head 6 to prevent the end of the pipeline detection head 6 from getting stuck. A conical surface 62 is formed on the other end surface, and water outlet holes 63 are evenly opened on the conical surface 62. The water injection pressure in the water outlet holes 63 can provide pressure for the movement of the pipeline detection head 6, further making the pipeline detection head move smoothly.

[0021] like Figure 3 As shown, a cavity 64 is opened in the pipeline detection head 6, the center of the cavity 64 is connected to the hollow tube 41, and the cavity 64 is also connected to the water outlet 63. The water first enters the cavity 64, and then the water passes through the cavity 64 and is ejected from the water outlet 63. The water ejected under pressure will provide thrust to the pipeline detection head 6, so that the pipeline detection head 6 moves more smoothly in the pipeline 7.

[0022] The hollow tube 41 is tightly matched with the pipeline detection head 6 , which improves the connection strength between the hollow tube 41 and the pipeline detection head 6 and prevents the pipeline detection head 6 from being separated from the hollow tube 41 under water pressure.

[0023] A water tank is provided in the vehicle body 1, which is connected to the hollow tube 41. The water tank provides water to the hollow tube 41, so that water flows out of the water outlet 63 of the pipeline detection head 6, providing thrust for the detection of the pipeline detection head 6, so that the pipeline detection head 6 can quickly enter the pipeline 7.

[0024] Detection process: First, tie the end of the cable to the side of the hollow tube close to the pipeline detection head, then put the pipeline detection head into the pipeline, and use the rotation of the motor to control the rotation of the drum, so that the hollow tube pushes the pipeline detection head into the pipeline and gradually goes deeper. When it encounters a jam, water will flow into the hollow tube and spray out from the water outlet through the cavity. At the same time, the sprayed water will provide pressure, making the pipeline detection head move more smoothly.

[0025] After the pipeline detection head is moved into position, the cable can be energized, and the position and length of the pipeline can be determined by detecting and positioning the energized cable.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
