Description
Technical Field
[0001] The present utility model application relates to the technical field of detectors, and specifically to a handheld underground pipeline detector. Background Art
[0002] Underground pipelines are the general term for various pipelines, cables, integrated pipe galleries, pipe trenches and their ancillary facilities built underground in cities. They undertake important functions for urban operation and are the "lifelines" of urban infrastructure. In addition, underground pipelines also include pipelines such as radio and television, traffic signals, public video surveillance, and industry, as well as their ancillary facilities, which together constitute a complex network of urban underground pipelines.
[0003] Most of the existing handheld underground pipeline detectors have a fixed length and are difficult to meet the detection requirements of pipelines at different depths. In complex or restricted detection environments, such as deeply buried pipelines and narrow spaces, detectors with a fixed length often cannot achieve ideal detection effects and may even be unable to complete the detection task. Therefore, developing a handheld underground pipeline detector with an adjustable length is of great significance for improving detection efficiency and flexibility. Summary of the Invention
[0004] In order to solve the problem that most of the existing handheld underground pipeline detectors have a fixed length and are difficult to meet the detection requirements of pipelines at different depths. In complex or restricted detection environments, such as deeply buried pipelines and narrow spaces, detectors with a fixed length often cannot achieve ideal detection effects and may even be unable to complete the detection task, the present utility model provides a handheld underground pipeline detector to solve the above problems.
[0005] To achieve the above object, the present utility model provides the following technical solutions:
[0006] A handheld underground pipeline detector includes a detector main body. An inner detection rod is slidably sleeved inside the detector main body. A partition is fixed in the middle inside the detector main body. A slot matching the shape of the partition is opened in the middle of the inner detection rod. A fixed block is fixed at the bottom end of the partition. A chute matching the shape of the fixed block is opened in the lower part inside the inner detection rod. A lead screw is rotatably connected between the fixed block and one end inside the detector main body. One end of the lead screw extends to the outer end of the detector main body. A first control knob is fixed at the end of the lead screw far from the fixed block. The lead screw is threadedly connected to one end of the inner detection rod close to the first control knob. One end of the inner detection rod far from the first control knob is provided with a connecting rod. A probe main body is fixed at the end of the connecting rod far from the detector main body.
[0007] Further, an adjusting outer rod is fixed above the interior of the inner detection rod. An adjusting inner rod is slidably sleeved inside the adjusting outer rod. One end of the adjusting inner rod away from the inner detection rod extends to the outside of the detector body and is fixed with a second control knob. The adjusting inner rod is rotatably connected to the detector body. One end of the adjusting outer rod away from the detector body is fixed with a first helical gear. The first helical gear is meshed and connected with a second helical gear. The second helical gear is fixedly connected with a connecting rod. The bottom end of the second helical gear is rotatably connected to the inner detection rod.
[0008] Further, a lighting lamp is fixed to the top end of the connecting rod. The lighting lamp is located at one end of the probe body close to the inner detection rod.
[0009] Further, the diameter of the first control knob is smaller than the radius of the detector body. Anti-slip stripes are provided on the outer side surface of the first control knob.
[0010] Further, the radius of the second control knob is the same as the radius of the first control knob. Anti-slip stripes are provided on the outer side surface of the second control knob.
[0011] Further, a limiting strip is fixed inside the adjusting outer rod. A limiting groove for cooperating with the limiting strip of the adjusting outer rod is provided on the outer side surface of the adjusting inner rod.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] 1. In the present utility model, by slidably connecting the inner detection rod inside the detector body and rotating the first control knob, the first control knob drives the lead screw to rotate, so that the lead screw drives the inner detection rod to move, and then the inner detection rod drives the probe body to move, solving the problem that most existing handheld underground pipeline detectors have a fixed length and are difficult to meet the detection requirements of pipelines at different depths. In complex or restricted detection environments, such as deeply buried pipelines and narrow spaces, detectors with a fixed length often cannot achieve an ideal detection effect and may even be unable to complete the detection task.
[0014] 2. In the present utility model, by rotating the second control knob, the adjusting inner rod is driven to rotate, so that the adjusting inner rod drives the adjusting outer rod to rotate. The adjusting outer rod drives the second helical gear to rotate through the first helical gear, so that the second helical gear drives the connecting rod to rotate, and thus the direction of the probe body can be adjusted, enabling the staff to conveniently achieve the detection purpose by adjusting the direction of the probe body in a complex environment.

Detailed implementation manners
[0021] To make the application purpose, features, and advantages of the present application more obvious and understandable, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the embodiments described below are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.
[0022] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4, a handheld underground pipeline detector, including a detector main body 1. An inner detection rod 2 is slidably sleeved inside the detector main body 1. A partition 14 is fixed in the middle inside the detector main body 1. A slot matching the shape of the partition 14 is opened in the middle of the inner detection rod 2. A fixed block 3 is fixed at the bottom end of the partition 14. A chute matching the shape of the fixed block 3 is opened below the inner part of the inner detection rod 2. A lead screw 4 is rotatably connected between the fixed block 3 and one end inside the detector main body 1. One end of the lead screw 4 extends to the outer end of the detector main body 1. A first control knob 5 is fixed at the end of the lead screw 4 away from the fixed block 3. The lead screw 4 is threadedly connected to one end of the inner detection rod 2 close to the first control knob 5. One end of the inner detection rod 2 away from the first control knob 5 is provided with a connecting rod 6. One end of the connecting rod 6 away from the detector main body 1 is fixed with a probe main body 7, so that the length of the detector main body 1 can be adjusted.
[0023] Specifically, a lighting lamp 8 is fixed at the top end of the connecting rod 6. The lighting lamp 8 is located at one end of the probe main body 7 close to the inner detection rod 2. The diameter of the first control knob 5 is smaller than the radius of the detector main body 1. Anti-slip stripes are arranged on the outer side surface of the first control knob 5 to prevent the first control knob 5 from contacting the second control knob 11.
[0024] As an optimized solution, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, an adjusting outer rod 9 is fixed above the inner part of the inner detection rod 2. An adjusting inner rod 10 is slidably sleeved inside the adjusting outer rod 9. One end of the adjusting inner rod 10 away from the inner detection rod 2 extends to the outside of the detector main body 1 and is fixed with a second control knob 11. The adjusting inner rod 10 is rotatably connected to the detector main body 1. One end of the adjusting outer rod 9 away from the detector main body 1 is fixed with a first bevel gear 12. The first bevel gear 12 is meshed with a second bevel gear 13. The second bevel gear 13 is fixed to the connecting rod 6. The bottom end of the second bevel gear 13 is rotatably connected to the inner detection rod 2, so that the direction of the probe main body 7 can be adjusted.
[0025] Specifically, the radius of the second control knob 11 is the same as the radius of the first control knob 5. Anti-slip stripes are arranged on the outer side surface of the second control knob 11. A limiting strip is fixed inside the adjusting outer rod 9. A limiting groove matching the limiting strip of the adjusting outer rod 9 is opened on the outer side surface of the adjusting inner rod 10 to facilitate the adjusting inner rod 10 to drive the adjusting outer rod 9 to rotate.
[0026] Working principle: When the staff inserts the main body 1 of the detector deep into the ground for detection, by rotating the first control knob 5, the first control knob 5 drives the lead screw 4 to rotate, so that the lead screw 4 drives the inner detection rod 2 to move, and then the inner detection rod 2 drives the probe main body 7 to move, making the length of the detector main body 1 adjustable. When the staff encounters a curved angle underground or needs to detect the surrounding conditions, by rotating the second control knob 11, the second control knob 11 drives the adjusting inner rod 10 to rotate, and at the same time the adjusting inner rod 10 drives the adjusting outer rod 9 to rotate, so that the adjusting outer rod 9 drives the first helical gear 12 to rotate. At the same time, the first helical gear 12 is meshed with the second helical gear 13, so that the second helical gear 13 drives the connecting rod 6 to rotate, making the connecting rod 6 drive the probe main body 7 to move, making the detection angle of the probe main body 7 adjustable. At the same time, when the probe main body 7 is detecting, the lighting lamp 8 illuminates the dark underground environment, making the detection of the probe main body 7 more convenient.
