A rolling buried pipeline rapid positioning and surveying device

Abstract

The invention discloses a rolling buried pipeline rapid positioning and surveying device, which relates to the field of municipal maintenance technology. This scheme aims to quickly and accurately locate the buried pipeline through the specific sound wave intensity recognition technology on the ground. During operation, the user swings the support rod by holding the handle, and the bottom end of the support rod drives the sealing chamber to swing, thereby guiding the ground wheel to roll and drive the connecting tube to rotate, so that the pickup moves along a circular trajectory. The pickup is compressed and contracted when it contacts the lowest point of the ground, and keeps in contact with the ground to collect sound. The design of the device prevents the pickup from being dragged when sampling evenly on the ground, thereby improving the detection accuracy. In addition, the device can also leave marks on the ground to quickly identify the detection area, simplifying the recognition and recording of the pipeline position. Generally speaking, compared with the traditional pipeline positioning technology, this scheme has the advantages of simple operation, high detection efficiency, high accuracy and low cost, and is suitable for pipeline survey work in various complex geological environments.

Description

Technical Field

[0001] The invention belongs to the technical field of municipal maintenance, and in particular relates to a rolling buried pipeline rapid positioning and surveying device. Background Art

[0002] In the context of urbanization and industrial development, the dense layout of underground pipelines has become a major challenge for urban infrastructure construction and maintenance. These pipelines include water pipes, gas pipes, oil pipelines, and telecommunication pipelines, and their safe and stable operation is crucial to the operation of the city. Therefore, effective positioning and detection of these buried pipelines is necessary to avoid accidental damage during construction, ensure construction safety, and promptly detect and repair damaged pipelines.

[0003] Although traditional pipeline positioning technologies such as acoustic detection and ground penetrating radar (GPR) can achieve pipeline positioning, they are usually inconvenient to operate, inefficient, costly, and require high technical skills of operators. Acoustic detection equipment requires a generator to be installed at one end of the pipeline to generate vibrations of a specific audio frequency, and then these vibration signals are captured by sensors on the ground. However, these traditional methods are greatly affected by the ground environment and pipeline materials, and the detection signals are easily interfered with, resulting in low positioning accuracy. In addition, these methods usually require single-point detection of each suspected location, which is inefficient, especially in complex urban environments.

[0004] In view of this, the present invention proposes a rolling buried pipeline rapid positioning survey device, which uses the intensity recognition technology of specific sound waves to quickly and accurately locate the pipeline through rolling operations on the ground. Compared with traditional technologies, this device simplifies the operation process, improves the positioning speed and accuracy, reduces costs, and reduces the dependence on the technical level of operators. Through this device, it is possible to achieve rapid survey of buried pipelines, effectively improving the efficiency and safety of urban infrastructure construction and maintenance work.

[0040] Beneficial effects:

[0041] When the present invention is in use, the handle can be held in the hand and the support rod can be swung to make the bottom end of the support rod swing with the sealing bin. In this process, the ground wheel rolls on the ground, and then the ground wheel rotates with the connecting tube of the driving assembly. The connecting tube starts to rotate under the support of the bearing and then rotates with the eccentric wheel. The limit clamp sliding on the surface of the eccentric wheel moves in a circular trajectory under the action of the eccentric rotation. During the movement, the limit clamp does not rotate by itself, but only moves in a trajectory, and moves with the lateral movement assembly and the pickup in a circular trajectory at the same time. When it moves to the lowest point, the pickup The device is completely compressed and contracted, and fits on the ground. When it gradually rises, the pickup extends and is in a continuous fit state to collect sound. Because the diameter difference between the ground wheel and the eccentric wheel is large, when the ground wheel moves a long distance, the height change of the pickup is small, so that the pickup fits on the ground and fits on the ground through the lateral movement component at a fixed position without being dragged until the eccentric wheel moves to the highest position with the limit card, and then it can be reset. As a whole, uniform multi-point detection is achieved within the swing range of a straight line or arc on the ground, so as to quickly identify the position of the buried pipeline;

[0042] In summary, when using this solution, you only need to simply swing your arms and wear aviation headphones to quickly identify the pipeline. Compared with the traditional point-by-point measurement of multiple positions, it is faster and more accurate to finally understand the location of the buried pipeline.

[0043] During use, the limit card moves along a circular trajectory and moves with the lugs and connecting rods on the surface at the same time. The connecting rod moves with a sliding sleeve fixed at one end. The horizontal movement of the sliding sleeve directly slides on the surface of the limit column without doing work. Only the vertical force will cause the limit column to reciprocate up and down. During this process, the limit column moves up and down and slides in the strip-shaped through groove at the same time, and makes the cam swing back and forth with the mounting seat as the center, and each swing is the state of the eccentric wheel rotating one circle, so that every time the eccentric wheel rotates one circle, its cam will swing to press the marking strip to the ground. After contacting the ground, it rolls with the ground wheel and leaves a mark on the ground, so that the mark can quickly mark and understand the detection area. It only needs to remember which areas have the largest specific sound signals.

[0044] During the inspection process, this solution can roll back and forth quickly on the ground in a zigzag shape and move forward quickly to quickly mark the pipeline position along the way, making it convenient for subsequent construction and marking.

DETAILED DESCRIPTION

[0069] The sealing bin 2 is disposed at the bottom end of the support rod 1, and an angle limiter 7 is installed between the sealing bin 2 and the support rod 1, and the angle limiter 7 is used to limit the rotation angle between the sealing bin 2 and the support rod 1;

[0070] Drive component 3;

[0071] The driving assembly 3 is rotatably connected to the arc-shaped side wall of the sealing bin 2, and is used to drive the pickup 6 to move and change its height to perform ground uniform distribution detection;

[0072] Transverse movement component 5;

[0073] The transverse moving assembly 5 is fixedly connected to the lower surface of the driving assembly 3, and the pickup 6 is fixedly connected to the lower surface of the transverse moving assembly 5. The transverse moving assembly 5 is used to maintain the transverse moving assembly 5 at the landing position;

[0074] Swing assembly 4;

[0075] The swing component 4 is fixed at one end of the sealing bin 2, and the swing component 4 is driven by the driving component 3 to swing, so as to record the number of times the pickup 6 falls to the ground;

[0076] Adjustment handle 11;

[0077] The adjustment handle 11 is disposed at the top end of the support rod 1, a pull rope 12 is installed at one end of the adjustment handle 11, and the other end of the pull rope 12 is fixedly connected to the angle limiter 7;

[0078] Processor 15;

[0079] The processor 15 is fixedly connected to the surface of the support pole 1, the input end of the processor 15 is electrically connected to the output end of the microphone 6, and one side of the processor 15 is electrically connected to an aviation headset 16 through an audio line;

[0080] Ground wheel 17;

[0081] The ground wheel 17 is fixedly connected to one end of the driving assembly 3 and is used to move the driving assembly 3 when rolling against the ground;

[0082] Battery pack 9;

[0083] Power supply array 10;

[0084] The battery pack 9 is fixedly connected to the inner wall of the sealed compartment 2 , and the power source array 10 is evenly distributed inside the battery pack 9 .

[0085] The rolling buried pipeline rapid positioning survey device proposed in this scheme realizes the rapid and accurate positioning of buried pipelines through simple operation procedures and specific sound wave intensity recognition technology. This device optimizes many shortcomings of traditional pipeline detection methods, such as operational complexity, low detection efficiency and high cost, and provides an efficient, low-cost and high-precision solution. Through handheld operation and uniform multi-point detection on the ground, as well as a design that facilitates construction marking, this scheme significantly improves the efficiency and accuracy of pipeline survey work, and is suitable for wide application in urban infrastructure construction and maintenance in various complex geological environments.

[0086] Specifically, Figure 7 As shown: a plurality of bearings 8 are fixedly connected to the inner wall of the driving assembly 3, and the plurality of bearings 8 are fixedly connected to the surface of the sealing bin 2 to support the rotation of the driving assembly 3 and the ground wheel 17 fixed on the surface thereof.

[0087] The bearings 8 are evenly distributed and fastened to the outer surface of the sealed bin 2, providing a stable and reliable support structure. The main function of the bearings 8 is to reduce the friction generated during the operation of the drive assembly 3, allowing the ground wheel 17 and other components connected thereto to rotate smoothly, thereby reducing energy consumption and extending the service life of the equipment.

[0088] Specifically, Figure 5 As shown: the angle limiter 7 includes a rotating pin 71 fixedly connected to one side of the sealing bin 2, and a pin seat 72 is movably connected to the surface of the rotating pin 71, and the pin seat 72 is fixedly connected to the bottom end of the support rod 1;

[0089] The angle limiter 7 also includes a partition 73 fixedly connected to the inner wall of the bottom end of the pin seat 72, a pull rod 74 slides through the surface of the partition 73, one end of the pull rod 74 is fixedly connected to a limiting frame 75, the limiting frame 75 is arranged on one side of the rotating pin 71, and a third spring 76 is fixed between the limiting frame 75 and the partition 73.

[0090] The structural design of the angle limiter 7 ingeniously realizes the precise control of the swing angle of the device. A rotating pin 71 is fixedly installed on one side of the sealing chamber 2, and a pin seat 72 is movably connected to the rotating pin 71 to form a fulcrum with adjustable angle. The pin seat 72 is further fixed to the bottom end of the support rod 1, so that the support rod 1 and the sealing chamber 2 can rotate within a certain angle without excessively deviating from the preset swing range.

[0091] The angle limiter 7 also includes a partition 73 fixed to the bottom end of the pin seat 72, and a sliding groove is provided on the partition 73 to guide the linear movement of the pull rod 74. One end of the pull rod 74 is connected to the limiting frame 75, which is arranged on one side of the rotating pin 71 to stabilize and limit the swing range of the support rod 1. When the operator adjusts the support rod 1, the pull rod 74 slides along the partition 73, thereby realizing the limiting change of the rotation angle by the displacement of the limiting frame 75. This setting not only increases the flexibility of the equipment, but also ensures the accuracy and stability of the detection under various ground conditions, thereby improving the efficiency and accuracy of the buried pipeline survey.

[0092] Specifically, Fig. 9 As shown: the driving assembly 3 includes a connecting tube 31 installed on the surface of a plurality of bearings 8, the ground wheel 17 is fixedly connected to one end of the connecting tube 31, an eccentric wheel 32 is fixedly connected to the surface of the connecting tube 31, and the arc-shaped side wall of the eccentric wheel 32 is limited to slide with a limiting clamp 33, and the lower surface of the limiting clamp 33 is fixedly connected to the upper surface of the transverse movement assembly 5;

[0093] A lug 34 is fixedly connected to one side of the limit clamp 33, a connecting rod 35 is fixedly connected to the surface of the lug 34, and the connecting rod 35 is fixedly connected to the surface of the swing assembly 4;

[0094] The connecting tube 31 is fixed on one side of the axis position of the eccentric wheel 32 .

[0095] The driving assembly 3 is a key part for realizing the precise movement of the pickup 6 in the present invention. It is composed of a plurality of connecting tubes 31 precisely mounted on the bearings 8, which ensures the stability and smoothness of the operation of the entire device. The ground wheel 17 is fastened to one end of the connecting tube 31. When the ground wheel 17 rolls along the ground, the connecting tube 31 rotates accordingly, driving the eccentric wheel 32 mounted on its surface to rotate together. The design of the eccentric wheel 32 allows the limit clamp 33 attached to its arc-shaped side wall to slide along a specific circular trajectory, and the formation of this trajectory is achieved by the difference in diameter between the eccentric wheel 32 and the ground wheel 17.

[0096] The lower surface of the limit clamp 33 is fixedly connected to the upper surface of the lateral movement assembly 5, thereby achieving the synchronous movement of the lateral movement assembly 5 and the pickup 6 it carries. In addition, the lug 34 on one side of the limit clamp 33 fixes the connecting rod 35, and the connecting rod 35 is connected to the surface of the swing assembly 4, forming a complex linkage mechanism. When the eccentric wheel 32 rotates, it can not only drive the lateral movement assembly 5 and the pickup 6 to move along the predetermined trajectory, but also drive the swing assembly 4 to produce a corresponding swing through the push of the connecting rod 35. This swing is crucial for recording the number of times the pickup 6 is detected to the ground.

[0097] The design of the entire drive assembly 3 not only achieves the coordination of the vertical and horizontal movements of the pickup 6, but also ensures the efficiency and accuracy of the device in surveying underground pipelines through precise mechanical linkage. This design effectively improves the working efficiency of the device and also ensures stable operation under complex ground conditions.

[0098] Specifically, Figure 4 As shown: one end of the pull rod 74 is fixedly connected to the bottom end of the pull rope 12, the pull rope 12 is slidably arranged on the inner wall of the support pole 1, and a handle 14 is fixed to the top end of the support pole 1.

[0099] The design of the pull rod 74 and the pull rope 12 constitutes a simple and effective mechanical linkage mechanism for adjusting and controlling the working state of the angle limiter 7, thereby achieving precise adjustment of the swing angle of the device. One end of the pull rod 74 is connected to the bottom end of the pull rope 12 in a fixed manner, ensuring that the force and movement transmitted between the two are synchronized and accurate. The pull rope 12 is set to slide along the inner wall of the support rod 1. This layout not only saves space, but also ensures smooth movement of the pull rope 12 during operation, reducing friction and wear.

[0100] When the operator pulls the pull rope 12 through the adjustment handle 11, the pull rope 12 then pulls the pull rod 74 connected thereto, causing the limiting frame 75 in the angle limiter 7 to adjust its position accordingly, thereby changing the rotation angle between the sealing bin 2 and the support rod 1. This design allows the user to flexibly adjust the swing angle of the device according to different ground conditions and detection requirements, thereby improving the adaptability and survey efficiency of the device in different environments.

[0101] In addition, setting the pull rope 12 on the inner wall of the support rod 1 not only optimizes the overall structure of the device and reduces the possible damage of the external exposed parts, but also provides a more intuitive and convenient operation method for the operator. By simply pulling the adjustment handle 11, the swing angle of the device can be finely controlled, making the survey of underground pipelines more efficient and accurate.

[0102] Specifically, Fig.10 As shown: the swing assembly 4 includes a mounting seat 45 fixedly connected to one end of the sealing bin 2, a cam 42 is slidably provided at the bottom end of the mounting seat 45, a strip-shaped through groove 43 is opened on one side of the cam 42, the inner wall of the strip-shaped through groove 43 is limited to slide with a limiting column 41, a sliding sleeve 44 is slidably provided on the surface of the limiting column 41, the sliding sleeve 44 is fixedly connected to the connecting rod 35, and a marking strip 46 for ground marking is fixedly provided on the surface of the cam 42.

[0103] The design details of the swing assembly 4 reflect the pursuit of accuracy and reliability of the present invention. The basic structure of the swing assembly 4 is formed by the mounting seat 45 installed at one end of the sealing bin 2 and the cam 42 cleverly arranged at the bottom of the mounting seat 45. The cam 42 is not only the driving source of the swing action, but the strip-shaped through groove 43 designed therein also provides an accurate sliding path for the limit column 41, thereby ensuring the accuracy of the swing action. It enables the ground to mark the exact distance when swinging.

[0104] Specifically, Figure 2 As shown: the surface of the top end of the support rod 1 is movably connected with a buckle 13 through a pin, and the buckle 13 is used to cooperate with the adjustment handle 11 to limit the position.

[0105] The main function of the buckle 13 is to cooperate with the adjustment handle 11. When the handle is pressed, the buckle 13 can hold the handle to prevent the handle from being reset.

[0106] Specifically, Fig.11As shown: the transverse movement assembly 5 includes a reinforcing rib 55 fixedly connected to the arc-shaped side wall of the limiting clamp 33, a horizontal guide rail 51 is fixedly connected below the reinforcing rib 55, a slider 52 is slidingly limited on the surface of the horizontal guide rail 51, two protective grooves 53 are provided on one side of the slider 52, a tension spring 54 is fixedly connected to the inner wall of the protective groove 53, and the other end of the tension spring 54 is fixedly connected to one end of the horizontal guide rail 51.

[0107] The design of the transverse moving assembly 5 fully considers the requirements of stability and flexibility, and realizes the precise transverse movement of the pickup 6 on the ground through the coordinated work of the reinforcing ribs 55, the horizontal guide rails 51, the slider 52, the protection groove 53 and the tension spring 54. The reinforcing ribs 55 are fixed on the arc-shaped side walls of the limit clamps 33, which increases the stability and bearing capacity of the structure, ensuring that the transverse moving assembly 5 can operate stably during the entire detection process.

[0108] The horizontal guide rail 51 is installed under the reinforcing rib 55, providing a platform for the limited sliding of the slider 52, allowing the slider 52 to move smoothly along the guide rail. This design is intended to achieve accurate lateral positioning of the pickup 6, and the tension spring 54 fixed on the inner wall of the protection groove 53 provides power support for the return position of the slider 52. The other end of the tension spring 54 is fixed to one end of the horizontal guide rail 51. Through the elastic force of the tension spring 54, it can be ensured that the slider 52 can automatically return to the initial position after completing a lateral movement, preparing for the next lateral movement.

[0109] It can ensure that the microphone 6 will not be displaced or dragged after being attached to the designated ground. When the microphone 6 is separated from the ground, it can be reset along with the slider 52 under the action of the tension spring 54.

[0110] The design of the transverse movement assembly 5 not only improves the operational flexibility and detection efficiency of the surveying device, but also ensures the accuracy and repeatability of the detection process through a sophisticated mechanical structure.

[0111] Specifically, Fig.12 As shown: the pickup 6 includes a base 61 fixedly connected to the lower surface of the slider 52, the inner wall of the base 61 is provided with a top head 62 which is limited and slidable, the upper surface of the top head 62 and the inner wall of the base 61 are fixedly connected with a first spring 63, the inner wall of the top head 62 is penetrated and slid with a ground nail 65, and the lower surface of the top head 62 is fixed with a ground cover 67 around the ground nail 65;

[0112] The inner wall of the top head 62 is provided with a micro-vibration sensor 66 for monitoring the ground nail 65 and the ground cover 67;

[0113] The top end of the ground nail 65 is fixedly connected to a second spring 64 . The top end of the second spring 64 is fixedly connected to the inner wall of the base 61 . The ground nail 65 fits and slides on the inner wall of the top head 62 .

[0114] The design of the pickup 6 is a key component for detecting specific underground sound wave vibration signals in the present invention. The pickup 6 includes a solid base 61, which is firmly connected to the lower surface of the slider 52 to ensure the stability of the pickup 6 during the entire detection process. The top head 62 can slide on the inner wall of the base 61 and fit on the ground under the action of the first spring 63. When the top head 62 is pressed to press the first spring 63 to shrink, its ground nail 65 can be inserted into the ground under the action of the second spring 64. The hardness of the second spring 64 is greater than that of the first spring 63, which can meet the requirements of the top head 62 fitting the ground and the ground nail 65 being inserted into the soil for more accurate detection. If there is a hard object blocking the ground, the second spring 64 will also shrink, so that the ground nail 65 can be inserted into the ground and released to the hard object and then stop.

[0115] When the present invention is in use, the handle 14 can be held and the support rod 1 can be swung to swing the bottom end of the support rod 1 with the sealing chamber 2. During this process, the ground wheel 17 is subjected to a ground friction force when in contact with the ground, causing the position of the angle limiter 7 at the bottom end of the support rod 1 to deflect. The specific deflection angle depends on the actual measurement needs. By pressing the adjustment handle 11, the adjustment handle 11 pulls the pull rope 12, so that the pull rope 12 slides with the pull rod 74 on the surface of the partition 73, and the pull rod 74 pulls the concave limit frame 75 away from the rotation. Pin 71 causes the rotating pin 71 to lose its limit, and as the distance increases, the swing amplitude of the rotating pin 71 increases, and at the same time, the limiting frame 75 presses the third spring 76. When the hand releases the adjusting handle 11, the third spring 76 resets the limiting frame 75, so that the sealing bin 2 can no longer swing and deflect, and is in a vertical state. According to the needs of measurement, the zigzag angle can be adjusted by directly grasping the opening and closing degree of the adjusting handle 11 by hand, and then the measured distance can be increased or decreased to meet the needs of use and can be quickly and dynamically regulated.

[0116] As the ground wheel 17 rotates, the connecting tube 31 of the driving assembly 3 rotates with it. The connecting tube 31 starts to rotate under the support of the bearing 8 and then rotates with the eccentric wheel 32. The limit clamp 33 sliding on the surface of the eccentric wheel 32 moves in a circular trajectory under the eccentric rotation. During the movement, the limit clamp 33 does not rotate by itself, but only moves in a trajectory, and moves with the transverse movement assembly 5 and the pickup 6 in a circular trajectory at the same time. When it moves to the lowest point, the pickup 6 is completely compressed and contracted. After gradually descending, the pickup 6 touches the ground. First, the position where it touches the ground will not move, because when the transverse movement assembly 5 maintains the overall movement, the pickup 6 touches the ground when it descends to a certain position, and continues to do so. When the base 61 descends, the base 61 is pressed downward. The base 61 is pressed downward to first maintain a downward elastic support of the top head 62 through the first spring 63, ensuring that the ground cover 67 contacts the ground, so that the micro-vibration sensor 66 can pick up the specified sound through the ground cover 67. As the pressure increases, the second spring 64 is thicker and more elastic, and can insert the ground nail 65 into the soil under pressure, so that the specified frequency can be better transmitted. When there is a hard object blocking below, the second spring 64 is deformed, and the ground nail 65 cannot continue to be inserted downward, and the sound can be picked up with the ground cover 67. After the movement is completed, the top head 62 completely slides out under the action of the first spring 63, and the ground nail 65 retracts again in a protective state;

[0117] The microphone 6 is attached to the ground and stretches and is in a continuous attached state to collect sound as it gradually rises. Because the diameter difference between the ground wheel 17 and the eccentric wheel 32 is large, when the ground wheel 17 has moved a long distance, the height change of the microphone 6 is still small (the ground wheel 17 has a large diameter, and the ground wheel 17 moves a large distance for the same rolling circle, but the coaxial eccentric wheel 32 has a smaller amplitude). At this time, the microphone 6 is attached to a specified ground surface, and it is attached to the ground under the downward pressure and will not move. The slider 52 above it is fixed to it, and it will Slide on the surface of the horizontal guide rail 51 and pull the tension spring 54 until the eccentric wheel 32 moves to the highest position with the limit clamp 33. At this time, the pickup 6 gradually extends, the pressure on the ground is reduced, and after leaving the ground, the detection is completed. The slider 52 is reset from the end of the horizontal guide rail 51 to the initial end of the horizontal guide rail 51 under the action of the tension spring 54, and the next detection can be carried out. As a whole, a uniform and fast multi-point detection of a straight line or arc on the ground is achieved within the swing range of the handheld support rod 1, thereby quickly identifying the position of the buried pipeline;

[0118] In summary, when using this solution, one only needs to swing one's arm and wear the aviation headset 16 to quickly identify the pipeline. Compared with the traditional method of measuring multiple positions one by one, it is faster and more accurate to finally understand the location of the buried pipeline.

[0119] During use, the limit card 33 moves along a circular trajectory and moves with the surface lug 34 and the connecting rod 35 at the same time. The connecting rod 35 moves with the sliding sleeve 44 fixed at one end. The horizontal movement of the sliding sleeve 44 directly slides on the surface of the limit column 41 without doing work. Only the vertical force will cause the limit column 41 to reciprocate up and down. During this process, the limit column 41 moves up and down and slides in the strip-shaped through groove 43 at the same time, and makes the cam 42 reciprocate around the mounting seat 45 as the center, and each swing is the state of the eccentric wheel 32 rotating one circle, so that every time the eccentric wheel 32 rotates one circle, its cam 42 will swing to press the marking strip 46 to the ground. After contacting the ground, it rolls with the ground wheel 17 and leaves a mark on the ground, so that the mark can quickly mark and understand the detection area. It only needs to remember which areas have the largest specific sound signals.

[0120] Among them combined Fig.14 You can know the sound size data when swinging in one direction and detecting multiple points

[0121] During the inspection process, this solution can roll back and forth quickly on the ground in a zigzag shape and move forward quickly to quickly mark the pipeline position along the way, making it convenient for subsequent construction and marking.
