DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1-6 The utility model provides an embodiment of an underground pipeline positioning device, comprising a pipeline detector 1, a plug-in box 2, a water-based paint box 3 and a rubbing shell 7. The plug-in box 2 is fixedly mounted on the bottom end of the pipeline detector 1, and the water-based paint box 3 is slidably plugged into the bottom end of the plug-in box 2. When the pipeline does not need to be marked, the water-based paint box 3 can be pulled out by external force to position the pipeline. The top outer side of the water-based paint box 3 is fixedly connected to the plug-in outer frame 4, which is slidably plugged into the inside of the plug-in box 2. The plug-in box 2 is used to push the top of the water-based paint box 3. The cover is sealed to prevent paint from leaking. Leakage holes 5 are evenly penetrated at the bottom of the water-based paint box 3. Support ears 6 are fixedly connected to the middle of the bottom ends of both sides of the water-based paint box 3. The inner side of the rubbing shell 7 is fixedly connected to a support bracket 8. Fixed ears 12 are fixedly connected to both sides of the rubbing shell 7. The top of the fixed ear 12 is fixedly connected to a sliding rod 14. A spring 13 is nested on the outside of the sliding rod 14. The top of the sliding rod 14 is threadedly connected to a limiting top cover 15, which is limited by the limiting top cover 15 to prevent the sliding rod 14 from slipping out of the supporting ears 6 and causing the rubbing shell 7 to fall.

[0023] The inner bottom end of the rubbing shell 7 is fixedly connected to a sponge rubbing strip 9, and the top end of the sponge rubbing strip 9 is fixedly connected to the bottom end of the support bracket 8. The sponge rubbing strip 9 has strong adsorption properties and can absorb paint for rubbing.

[0024] The top of the supporting bracket 8 is evenly fixedly connected with a movable rod valve 11, and the outside of the movable rod valve 11 is evenly provided with a drainage groove 10. The movable rod valve 11 is slidably connected to the inner side of the leakage hole 5. When the bottom end of the limiting top cover 15 is close to the top of the supporting ear 6 in the normal state, the drainage groove 10 is located below the leakage hole 5, and the leakage hole 5 is blocked by the movable rod valve 11 to prevent leakage. When the movable rod valve 11 slides to the drainage groove 10 and is above the leakage hole 5, the water-soluble paint in the water-based paint box 3 flows into the interior of the rubbing shell 7 through the drainage groove 10, and the water-soluble paint is absorbed by the sponge rubbing strip 9 and conducted to the ground for rubbing.

[0025] The sliding rod 14 is slidably connected to the supporting ear 6, the top end of the spring 13 is close to the bottom end of the supporting ear 6, and the bottom end of the spring 13 is close to the top end of the fixed support ear 12. The elasticity of the spring 13 restores the initial state of the rubbing shell 7. After the rubbing is completed, when the pipeline detector 1 is lifted upward, the spring 13 loses pressure and rebounds. The rebound of the spring 13 squeezes the fixed support ear 12 downward, and the movement of the fixed support ear 12 drives the rubbing shell 7 to move downward and return to its initial state.

[0026] The sponge rubbing strip 9 is designed as a bidirectional arrow. The straight direction of the sponge rubbing strip 9 and the straight direction of the handle of the pipeline detector 1 are in the same direction. The direction of the arrow makes it easy to understand the wiring direction of the pipeline.

[0027] Working principle: During use, first put water-soluble paint into the water-based paint box 3, then push the water-based paint box 3 by external force, and the water-based paint box 3 is plugged into the inside of the plug-in box 2 through the plug-in outer frame 4, and then the pipeline is located by the pipeline detector 1. When the pipeline is found, the direction of the pipeline is determined by adjusting the direction of the pipeline detector 1. When the pipeline and the plug-in box 2 are in the same straight line, the pipeline detector 1 is moved downward by external force. The movement of the pipeline detector 1 drives the plug-in box 2 to move downward, and the movement of the plug-in box 2 The water-based paint box 3 and the rubbing shell 7 are driven to move downward, and the movement of the rubbing shell 7 drives the sponge rubbing strip 9 to move downward. When the sponge rubbing strip 9 moves to contact the ground, it continues to push the pipeline detector 1 downward. At this time, the sponge rubbing strip 9 is compressed to the inner side of the bottom end of the rubbing shell 7 by the pressure. When the bottom end of the rubbing shell 7 contacts the ground, the rubbing shell 7 and the fixed support ear 12 remain stationary under the action of pressure, and the water-based paint box 3 continues to move downward. At this time, the sliding rod 14 slides on the support ear 6, and the movable rod valve 11 When the piston rod 11 is in the state of being pressed down, the piston rod 12 of piston rod 13 is in the state of being pressed down, and piston rod 13 is in the state of being pressed down.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
