Description

Technical Field

[0001] This utility model belongs to the field of pipe detector technology, specifically relating to a pipe detector for underground gas pipelines. Background Technology

[0002] A pipe detector is an instrument used to detect the location, direction, and depth of underground pipelines. Currently, the location of PE gas pipelines is mostly detected using acoustic pipe detectors. When using an acoustic pipe detector, a device that generates sound waves of a specific frequency is placed inside the pipeline. The sound waves then propagate through the pipeline and radiate through the pipe wall into the surrounding medium (such as soil). When a receiving sensor on the ground receives these sound wave signals, the location and condition of the pipeline are determined by analyzing the propagation time, frequency, and other characteristics of the sound waves. However, after the gas pipeline location is detected, the pipe detector itself does not have a marking function, requiring personnel to use additional marking equipment to mark the location of the gas pipeline, making the detection and marking process rather cumbersome. Summary of the Invention

[0003] The purpose of this invention is to provide a pipe detector for underground gas pipelines, which can directly mark the location of the gas pipeline after it is detected, thus making the pipe detection and marking process simpler.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] A pipe detector for underground gas pipelines includes a receiver, a transmission line, and an acoustic sensor. The two ends of the transmission line are connected to the output of the receiver and the output of the acoustic sensor, respectively. A movable sleeve is fitted over the surface of the transmission line, and a handle is fixedly connected to the surface of the movable sleeve. A remote control switch is fixedly connected to the upper surface of the handle. A support plate is fixedly connected to the surface of the acoustic sensor. A through hole is formed inside the support plate, and a marking mechanism is fixedly connected to the inner wall of the through hole and the upper surface of the support plate. The marking mechanism is electrically connected to the transmission line via a wire and is signal-connected to the remote control switch.

[0006] The present invention is further configured such that the movable sleeve includes a threaded cylinder, a strip-shaped hole, a cylinder, a pressing post, and a nut. The inner wall of the threaded cylinder is in contact with the surface of the transmission line, and the surface of the threaded cylinder is fixedly connected to the inner wall of the handle. The strip-shaped hole is opened on the threaded cylinder. Both ends of the cylinder are fixedly connected to the inner wall of the strip-shaped hole. The inner wall of the pressing post is rotatably connected to the surface of the cylinder. The inner wall of the nut is threadedly connected to the inner wall of the threaded cylinder. The inner wall of the nut and the surface of the transmission line are both in contact with the surface of the pressing post.

[0007] The present invention is further configured such that the marking mechanism includes a column, a powder box, a powder outlet pipe, a solenoid valve, a powder inlet, and a sealing plug. The bottom end of the column is fixedly connected to the upper surface of the support plate, the top end of the column is fixedly connected to the bottom of the powder box, the top end of the powder outlet pipe is fixedly connected to the bottom of the powder box, the bottom end of the powder outlet pipe is fixedly connected to the top end of the solenoid valve, the surface of the powder outlet pipe is fixedly connected to the inner wall of the through hole, the powder inlet is opened on the upper surface of the powder box, the inner wall of the powder inlet is in contact with the surface of the sealing plug, the solenoid valve is electrically connected to a transmission line via a wire, and the solenoid valve is signal-connected to a remote control switch.

[0008] The present invention is further configured such that a support leg is fixedly connected to the bottom of the support plate, and the bottom of the support leg is in the same horizontal plane as the bottom of the acoustic sensor.

[0009] The present invention is further configured such that a connecting block is fixedly connected to the surface of the powder outlet pipe, a vibration motor is fixedly connected to the right side of the connecting block, the vibration motor is electrically connected to a transmission line via a wire, and the vibration motor is signal-connected to a remote control switch.

[0010] The present invention is further configured such that a U-shaped post is fixedly connected to the bottom of the handle.

[0011] The technical effects achieved by this utility model are as follows:

[0012] This utility model discloses a pipe detector for underground gas pipelines. Through a remote control switch on the handle, the user can remotely control the solenoid valve on the marking mechanism. When the solenoid valve is opened, the marking powder in the powder box will be discharged through the powder outlet pipe and fall to the ground. At this time, the location of the gas pipeline can be marked by the marking powder on the ground. This allows the pipe detector to directly mark the location of the gas pipeline after it is detected, thus making the detection and marking process simpler. At the same time, the vibration motor can shake the marking powder stuck in the powder outlet pipe and allow the marking powder to be discharged normally.

[0013] This utility model discloses a pipe detector for underground gas pipelines.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] like Figures 1 to 9As shown, a pipe detector for underground gas pipelines includes a receiver 1, a transmission line 2, and an acoustic sensor 3. The two ends of the transmission line 2 are connected to the output ends of the receiver 1 and the acoustic sensor 3, respectively. A movable sleeve 4 is fitted on the surface of the transmission line 2, and a handle 5 is fixedly connected to the surface of the movable sleeve 4. A U-shaped post 13 is fixedly connected to the bottom of the handle 5. When a hand is inserted into the U-shaped post 13, the U-shaped post 13 prevents the user from easily slipping out of their hand when holding the handle 5. A remote control switch 6 is fixedly connected to the upper surface of the handle 5. A support plate 7 is fixedly connected to the surface of the acoustic sensor 3. A through hole 8 is opened inside the support plate 7. A marking mechanism 9 is fixedly connected to the inner wall of the through hole 8 and the upper surface of the support plate 7. The marking mechanism 9 is electrically connected to the transmission line 2 through a wire and is signal-connected to the remote control switch 6. A support leg 10 is fixedly connected to the bottom of the support plate 7. The bottom of the support leg 10 is in the same horizontal plane as the bottom of the acoustic sensor 3. The support leg 10 prevents the acoustic sensor 3 from tipping over when placed on the ground.

[0028] The marking mechanism 9 includes a column 901, a powder box 902, a powder outlet pipe 903, a solenoid valve 904, a powder inlet 905, and a sealing plug 906. The bottom end of the column 901 is fixedly connected to the upper surface of the support plate 7, the top end of the column 901 is fixedly connected to the bottom of the powder box 902, the top end of the powder outlet pipe 903 is fixedly connected to the bottom of the powder box 902, the bottom end of the powder outlet pipe 903 is fixedly connected to the top end of the solenoid valve 904, the surface of the powder outlet pipe 903 is fixedly connected to the inner wall of the through hole 8, the powder inlet 905 is opened on the upper surface of the powder box 902, the inner wall of the powder inlet 905 is in contact with the surface of the sealing plug 906, the solenoid valve 904 is electrically connected to the transmission line 2 through a wire, and the solenoid valve 904 is signal connected to the remote control switch 6.

[0029] It should be noted that the solenoid valve 904 controls the switch at the bottom of the powder outlet pipe 903. The user can remotely control the solenoid valve 904 on the marking mechanism 9 via the remote control switch 6. When the solenoid valve 904 is open, the marking powder in the powder box 902 will be discharged through the powder outlet pipe 903 and fall to the ground. At this time, the location of the gas pipeline can be marked by the marking powder on the ground. When the solenoid valve 904 is closed, the bottom of the powder outlet pipe 903 is sealed by the solenoid valve 904.

[0030] like Figures 1 to 6As shown, the movable sleeve 4 includes a threaded cylinder 401, a strip hole 402, a cylinder 403, a pressing post 404, and a nut 405. The inner wall of the threaded cylinder 401 is in contact with the surface of the transmission line 2, and the surface of the threaded cylinder 401 is fixedly connected to the inner wall of the handle 5. The strip hole 402 is opened on the threaded cylinder 401. Both ends of the cylinder 403 are fixedly connected to the inner wall of the strip hole 402. The inner wall of the pressing post 404 is rotatably connected to the surface of the cylinder 403. The inner wall of the nut 405 is threadedly connected to the inner wall of the threaded cylinder 401. The inner wall of the nut 405 and the surface of the transmission line 2 are both in contact with the surface of the pressing post 404.

[0031] It should be noted that when the user rotates the nut 405, the distance between the nut 405 and the handle 5 changes through the cooperation between the nut 405 and the threaded sleeve 401. When the distance between the nut 405 and the handle 5 increases, the pressing column 404 will release the transmission line 2, allowing the movable sleeve 4 to slide on the transmission line 2. When the distance between the nut 405 and the handle 5 decreases, the pressing column 404 can press the transmission line 2 through the nut 405, and the friction between the pressing column 404 and the transmission line 2 prevents the movable sleeve 4 from moving on the transmission line 2. Thus, through the movable sleeve 4, the distance between the handle 5 and the acoustic sensor 3 can be adjusted according to the user's height, allowing users of different heights to use the probe in a comfortable posture.

[0032] like Figures 1 to 8 As shown, a connecting block 11 is fixedly connected to the surface of the powder outlet pipe 903, and a vibration motor 12 is fixedly connected to the right side of the connecting block 11. The vibration motor 12 is electrically connected to the transmission line 2 through a wire, and the vibration motor 12 is signal connected to the remote control switch 6.

[0033] It should be noted that when the vibration motor 12 is turned on, the vibration motor 12 can shake the marking powder stuck in the powder outlet pipe 903 and allow the marking powder to be discharged normally.

[0034] The working principle of this invention is as follows: First, the transmitter is fixed to an exposed gas pipeline and emits sound waves of a specific frequency into the gas pipeline. Then, the sound wave sensor 3 is placed on the ground and slowly moved. When the sound wave sensor 3 receives the sound wave signal, it displays information such as signal strength and frequency on the receiver 1. Generally, the strongest signal is usually located directly above the pipeline. At this point, the user can determine the location of the gas pipeline based on the information displayed on the receiver 1.

[0035] Once the location of the gas pipeline is found, move the solenoid valve 904 to the corresponding position. Then, open the solenoid valve 904 using the remote control switch 6, and the marking powder in the powder box 902 will fall to the ground through the powder outlet pipe 903. At this time, the location of the gas pipeline can be marked by the marking powder on the ground. Meanwhile, the solenoid valve 904 will automatically close after being open for a period of time, and the marking powder will no longer be discharged through the closed solenoid valve 904.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
