Description

Technical Field

[0001] The invention relates to the technical field of pipeline detection, and in particular to an adjustable underground pipeline detection device. Background Art

[0002] Underground pipelines refer to pipelines, cables, integrated pipeline corridors, trenches and their ancillary facilities for water supply, drainage, gas, heat, electricity, communications, lighting, radio and television, traffic signals, public video surveillance, industry, etc. built below the ground in the city.

[0003] With the acceleration of urbanization, the laying and maintenance of underground pipelines (such as water pipes, drainage pipes, gas pipes, power cables, etc.) have become increasingly important. These pipelines are an important part of urban infrastructure and play an irreplaceable role in ensuring the normal operation of the city. However, since underground pipelines are often buried under the surface, and over time, the original pipeline data may be lost or deviate from the actual situation, which brings great challenges to the maintenance, renovation and new construction of pipelines. Especially during construction activities, if the specific location of underground pipelines is not accurately understood, it is easy to cause pipeline damage, which will not only lead to economic losses, but also may cause safety accidents.

[0004] Existing underground pipeline detection is usually carried out by manually walking on the road with a handheld detection instrument. The detection process is cumbersome, labor-intensive, and has low work efficiency. Although there are currently devices for detecting underground pipelines, such as the authorized patent with application number CN202123272490.5, its structure is relatively simple. After the pipeline is detected, it is necessary to manually spray paint to mark the position of the pipeline, which is time-consuming and labor-intensive. Moreover, in strong winds, it is difficult to spray the precise position of the pipeline, resulting in poor practicality. Therefore, the existing equipment needs to be improved.

[0005] Therefore, an adjustable underground pipeline detection device is needed to solve the above problems. Summary of the invention

[0006] In order to solve the above problem, that is, to solve the problem that the existing underground pipeline detection equipment cannot mark the detection position in time during detection, the present invention provides an adjustable underground pipeline detection device.

[0007] An adjustable underground pipeline detection device comprises a traveling mechanism, wherein a detection mechanism is arranged on the traveling mechanism, wherein the detection mechanism comprises a detection member, wherein the detection member comprises a first probe, wherein the detection mechanism further comprises a marking member, wherein the marking member is arranged in the traveling direction of the first probe, wherein the marking member comprises a storage cylinder with an opening at the top, wherein the storage cylinder contains marking powder, wherein a marking hole opening downward is provided at the bottom end of the storage cylinder, a closing cover is threadedly connected to the top end of the storage cylinder, a marking motor is fixedly connected to the inner wall of the closing cover, an output end of the marking motor is fixedly connected to a rotating shaft, and a rotating plate is fixedly connected to the bottom end of the rotating shaft, wherein a discharge hole is provided on the rotating plate, and the discharge hole can be connected to the marking hole.

[0008] Specifically, during use, when it is necessary to detect the underground pipeline, start the first probe, and at the same time start the traveling mechanism, the traveling mechanism drives the first probe to move, when the first probe detects the underground pipeline, the traveling mechanism moves along the axial direction of the underground pipeline, and the first probe continues to detect the underground pipeline, and at the same time start the marking motor, the output end of the marking motor drives the rotating shaft to rotate, and the rotating shaft drives the rotating plate to rotate, during the rotation of the rotating plate, when the discharge hole is connected with the marking hole, stop the marking motor, and the marking powder in the storage cylinder is discharged through the discharge hole and the marking hole, and then the marking powder falls on the ground to mark the underground pipeline; when the first probe fails to detect the underground pipeline during its movement, start the marking motor again, and the output end of the marking motor drives the rotating plate to rotate, so that the marking hole is disconnected from the discharge hole, and the discharge of the marking powder is stopped; when the marking powder in the storage cylinder is used up, unscrew the closing cover from the storage cylinder, and then replenish the marking powder into the marking cylinder.

[0009] Through the setting of the first probe, underground pipelines can be detected, and at the same time, through the setting of the traveling mechanism, the first probe can be driven to move, so that the first probe can automatically detect underground pipelines, saving manpower and improving work efficiency; at the same time, through the setting of the marking part, during the detection process of the first probe, the rotating plate can be rotated to connect the marking hole with the discharge hole, so that the marking hole discharges marking powder on the ground, and the position of the detected underground pipeline can be marked in time, which is convenient for subsequent work.

[0010] Furthermore, the first probe is a prior art and will not be described in detail.

[0011] Preferably, seven stirring rod groups are arranged on the rotating shaft at equal intervals along the axial direction, and the stirring rod group includes a fixed sleeve fixedly sleeved on the rotating shaft, and four stirring rods are evenly fixedly connected to the fixed sleeve along the circumferential direction.

[0012] Specifically, when in use, when the rotating shaft rotates, the rotating shaft drives the fixed sleeve to rotate, and the fixed sleeve drives the stirring rod to rotate. The stirring rod breaks up the marking powder in the storage cylinder to prevent the marking powder in the storage cylinder from clumping.

[0013] By setting the stirring rod group, when the rotating shaft rotates, the rotating shaft can drive the fixed sleeve to rotate, and the fixed sleeve drives the stirring rod to rotate. The stirring rod breaks up the marking powder in the storage cylinder to prevent the marking powder in the storage cylinder from clumping and being unable to be discharged, affecting the normal progress of the marking work.

[0014] Preferably, a discharge nozzle is fixedly connected to the marking hole, the discharge nozzle is communicated with the marking hole, and a nozzle opening opening downward is formed in the discharge nozzle.

[0015] Preferably, the detection member further comprises a mounting rod fixedly connected to the first probe, and the mounting rod is connected to the traveling mechanism.

[0016] Specifically, when in use, the first probe is installed on the traveling mechanism through the installation rod. When the traveling mechanism moves, the traveling mechanism drives the installation rod to move, and the installation rod drives the first probe to move.

[0017] Preferably, the detection mechanism also includes an auxiliary detection member, which includes a mounting plate fixedly mounted on the mounting rod, wherein both ends of the mounting plate are respectively fixedly connected to fixing rods, and the lower end of each fixing rod is fixedly connected to a second probe, and the length direction of the mounting plate is perpendicular to the travel direction of the traveling mechanism.

[0018] Specifically, during use, when the traveling mechanism moves, the traveling mechanism drives the mounting rod to move, the mounting rod drives the mounting plate to move, and the mounting plate drives the second probe to move. During the movement of the second probe, both sides of the pipeline detected by the first probe are detected to detect the bifurcation of the underground pipeline.

[0019] By setting up the auxiliary detection part, when the first probe is detecting the underground pipeline, the second probe can be used to detect both sides of the underground pipeline, so as to detect the bifurcation of the underground pipeline and facilitate the comprehensive detection of the underground pipeline.

[0020] Furthermore, the second probe is a prior art and will not be described in detail.

[0021] Preferably, two marking members are symmetrically fixedly connected to the mounting plate, and the two marking members are respectively located on one side of the mounting plate close to the two second probes.

[0022] Specifically, during use, when the second probe detects an underground pipeline, the second probe sends a signal to the controller, and the controller controls the marking motor in the marking part near the second probe to start, so that the discharge hole in the marking part is connected to the marking hole, so that the marking powder is discharged from the marking hole, and the marking powder marks the ground; when the detection signal of the second probe disappears, the marking motor is started again to disconnect the discharge hole from the marking hole.

[0023] By setting the marking parts close to the two second probes, the bifurcation of the underground pipeline can be marked after the second probe detects the bifurcation of the underground pipeline, which is convenient for operators to carry out pipeline construction and other work.

[0024] Preferably, the detection mechanism also includes a steering mechanism, which includes a steering motor fixedly connected to the travel mechanism, the output end of the steering motor is fixedly connected to the mounting plate, two electric push rods are symmetrically fixedly connected to the lower side of the mounting plate, the output ends of the two electric push rods are fixedly connected to a steering wheel, the steering wheel is gap-mounted on the mounting rod, and four insertion rods are evenly fixedly connected to the lower side of the steering wheel along the circumferential direction, and the lower ends of the insertion rods are pointed.

[0025] Specifically, during use, when the detection signal of the first probe is interrupted, if the second probes on both sides can still detect the signal, the electric push rod is started, and the output end of the electric push rod drives the steering wheel to move downward, and the steering wheel drives the insertion rod to move downward. When the insertion rod is fully inserted into the ground, the traveling mechanism is lifted up, and the traveling mechanism is separated from the ground. Then, the steering motor is started, and the steering motor rotates 90°, causing the traveling mechanism to rotate 90°, and then the electric push rod is retracted, and the electric push rod drives the insertion rod to reset, so that the traveling mechanism contacts the ground again, and then the traveling mechanism is started again to continue detecting the bifurcation of the underground pipeline.

[0026] By setting the steering mechanism, the traveling mechanism can be turned, and cooperate with the auxiliary detection component to enable the traveling mechanism to continue to detect the bifurcation of the underground pipeline, further improving the comprehensiveness of the underground pipeline detection.

[0027] Furthermore, the electric push rod is a prior art and will not be described in detail.

[0029] Specifically, when in use, when the traveling mechanism needs to move, the traveling motor is started, the output end of the traveling motor drives the traveling shaft to rotate, and the traveling shaft drives the traveling wheel to rotate, so that the frame moves, thereby making the detection mechanism move.

[0030] By setting the traveling mechanism, the traveling motor can drive the traveling wheel to rotate, so that the frame moves, and the frame drives the detection mechanism to detect the underground pipeline.

[0031] Preferably, the travel mechanism also includes a pushing member arranged on the frame, and the pushing member includes two hinged forks symmetrically fixedly connected to the frame, each of the hinged forks is rotatably connected to a connecting plate, the ends of the two connecting plates are fixedly connected to push rods, and a locking member is arranged between the connecting plate and the frame.

[0032] Specifically, in the initial state, the connecting plate is parallel to the frame; when the detection device needs to be pushed, the locking piece is unlocked, the connecting plate is rotated so that the connecting plate is perpendicular to the frame, and then the push rod is pushed to push the detection device to move.

[0033] By providing the pushing member, the detection device can be pushed, thereby facilitating the movement of the detection device.

[0034] Preferably, the locking member includes a fixed shaft fixedly connected between the two connecting plates, a square sleeve is provided on the fixed shaft, a rotating shaft is rotatably connected to the frame, a torsion spring is connected between the rotating shaft and the frame, an L-shaped locking rod is fixedly connected to the rotating shaft, and the lower side surface of the locking rod is in contact with the top surface of the square sleeve.

[0035] Specifically, when in use, when the connecting plate needs to be flipped, the locking rod is rotated so that the locking rod drives the rotating shaft to rotate 90°, and at the same time the rotating shaft accumulates force on the torsion spring, and then the connecting plate is flipped. After the connecting plate is flipped 90°, the locking rod is released, so that the locking rod is reset under the action of the torsion spring, limiting the rotation of the square sleeve, thereby locking the connecting plate, making it convenient for the user to push the push rod.

[0036] By setting the locking member, the connecting plate can be locked, which facilitates the folding and pushing of the pushing member, makes it easier for users to use the device and improves the passability of the device in terms of height.

[0056] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0057] like Figure 1 , 2As shown in Figures 3 and 6, an embodiment of the present invention discloses an adjustable underground pipeline detection device, comprising a traveling mechanism 1, on which a detection mechanism 2 is arranged, the detection mechanism 2 comprises a detection member 21, the detection member 21 comprises a first probe 211, the detection mechanism 2 further comprises a marking member 22, the marking member 22 is arranged in the traveling direction of the first probe 211, the marking member 22 comprises a storage cylinder 221 with an opening at the top, the storage cylinder 221 contains marking powder, a marking hole 222 opening downward is provided at the bottom end of the storage cylinder 221, a closing cover 223 is threadedly connected to the top end of the storage cylinder 221, a marking motor 224 is fixedly connected to the inner wall of the closing cover 223, a rotating shaft 225 is fixedly connected to the output end of the marking motor 224, a rotating plate 226 is fixedly connected to the bottom end of the rotating shaft 225, a discharge hole 227 is provided on the rotating plate 226, and the discharge hole 227 can be communicated with the marking hole 222.

[0058] Specifically, when it is necessary to detect the underground pipeline, the first probe 211 is started, and the travel mechanism 1 is started at the same time. The travel mechanism 1 drives the first probe 211 to move. When the first probe 211 detects the underground pipeline, the travel mechanism 1 moves along the axial direction of the underground pipeline. At the same time, the first probe 211 continuously detects the underground pipeline, and the marking motor 224 is started at the same time. The output end of the marking motor 224 drives the rotating shaft 225 to rotate, and the rotating shaft 225 drives the rotating plate 226 to rotate. During the rotation of the rotating plate 226, when the discharge hole 227 is connected with the marking hole 222 , stop the marking motor 224, and the marking powder in the storage tube 221 is discharged through the discharge hole 227 and the marking hole 222, and then the marking powder falls on the ground to mark the underground pipeline; when the first probe 211 does not detect the underground pipeline during its movement, start the marking motor 224 again, and the output end of the marking motor 224 drives the rotating plate 226 to rotate, so that the marking hole 222 is disconnected from the discharge hole 227, and the discharge of the marking powder is stopped; when the marking powder in the storage tube 221 is used up, the closing cover 223 is unscrewed from the storage tube 221, and then the marking powder is replenished into the marking tube 221.

[0059] Through the setting of the first probe 211, underground pipelines can be detected. At the same time, through the setting of the traveling mechanism 1, the first probe 211 can be driven to move, so that the first probe 211 can automatically detect underground pipelines, saving manpower and improving work efficiency. At the same time, through the setting of the marking part 22, during the detection process of the first probe 211, the rotating plate 226 can be rotated to connect the marking hole 222 with the discharge hole 227, so that the marking hole 222 discharges marking powder on the ground, and the position of the detected underground pipeline is marked in time, which is convenient for subsequent work.

[0060] Furthermore, the first probe 211 is a prior art and will not be described in detail.

[0061] like Figure 6 As shown, seven stirring rod groups are arranged on the rotating shaft 225 at equal intervals along the axial direction. The stirring rod group includes a fixed sleeve 228 fixedly sleeved on the rotating shaft 225, and four stirring rods 229 are evenly fixedly connected to the fixed sleeve 228 along the circumferential direction.

[0062] Specifically, when in use, when the rotating shaft 225 rotates, the rotating shaft 225 drives the fixed sleeve 228 to rotate, and the fixed sleeve 228 drives the stirring rod 229 to rotate. The stirring rod 229 breaks up the marking powder in the storage tube 221 to prevent the marking powder in the storage tube 221 from clumping.

[0063] By setting the stirring rod group, when the rotating shaft 225 rotates, the rotating shaft 225 can drive the fixed sleeve 228 to rotate, and the fixed sleeve 228 drives the stirring rod 229 to rotate. The stirring rod 229 breaks up the marking powder in the storage tube 221 to prevent the marking powder in the storage tube 221 from clumping and being unable to be discharged, which affects the normal progress of the marking work.

[0064] like Figure 6 As shown, a discharge nozzle is fixedly connected to the marking hole 222 , the discharge nozzle is communicated with the marking hole 222 , and a nozzle opening opening downward is formed in the discharge nozzle.

[0065] like Figure 3 As shown, the detection member 21 further includes a mounting rod 212 fixedly connected to the first probe 211 , and the mounting rod 212 is connected to the traveling mechanism 1 .

[0066] Specifically, when in use, the first probe 211 is installed on the traveling mechanism 1 through the installation rod 212. When the traveling mechanism 1 moves, the traveling mechanism 1 drives the installation rod 212 to move, and the installation rod 212 drives the first probe 211 to move.

[0067] like Figure 2 , 3 As shown, the detection mechanism 2 also includes an auxiliary detection member 23, which includes a mounting plate 231 fixedly mounted on the mounting rod 212, and both ends of the mounting plate 231 are respectively fixedly connected with fixing rods 232, and the lower end of each fixing rod 232 is fixedly connected with a second probe 233, and the length direction of the mounting plate 231 is perpendicular to the travel direction of the traveling mechanism 1.

[0068] Specifically, during use, when the traveling mechanism 1 moves, the traveling mechanism 1 drives the mounting rod 212 to move, the mounting rod 212 drives the mounting plate 231 to move, and the mounting plate 231 drives the second probe 233 to move. During the movement of the second probe 233, both sides of the pipeline detected by the first probe 211 are detected to detect the bifurcation of the underground pipeline.

[0069] By setting the auxiliary detection part 23, when the first probe 211 detects the underground pipeline, the second probe 233 can detect both sides of the underground pipeline, so as to detect the bifurcation of the underground pipeline and facilitate the comprehensive detection of the underground pipeline.

[0070] Furthermore, the second probe 233 is a prior art and will not be described in detail.

[0071] like Figure 3 As shown, two marking members 22 are symmetrically fixedly connected to the mounting plate 231 , and the two marking members 22 are respectively located on one side of the mounting plate 231 close to the two second probes 233 .

[0072] Specifically, during use, when the second probe 233 detects an underground pipeline, the second probe 233 sends a signal to the controller, and the controller controls the marking motor 224 in the marking part 22 near the second probe 233 to start, so that the discharge hole 227 in the marking part 22 is connected with the marking hole 222, so that the marking powder is discharged from the marking hole 222, so that the marking powder marks the ground; when the detection signal of the second probe 233 disappears, the marking motor 224 is started again, so that the discharge hole 227 is disconnected from the marking hole 222.

[0073] By setting the marking member 22 close to the two second probes 233, the bifurcation of the underground pipeline can be marked after the second probe 233 detects the bifurcation of the underground pipeline, which is convenient for operators to perform pipeline construction and other work.

[0074] like Figure 2 , 3 As shown, the detection mechanism 2 also includes a steering mechanism 24, and the steering mechanism 24 includes a steering motor 241 fixedly connected to the travel mechanism 1, and the output end of the steering motor 241 is fixedly connected to the mounting plate 231, and two electric push rods 242 are symmetrically fixedly connected to the lower side of the mounting plate 231, and the output ends of the two electric push rods 242 are fixedly connected to a steering wheel 243, and the steering wheel 243 is gap-mounted on the mounting rod 212, and the lower side of the steering wheel 243 is evenly fixedly connected with four insertion rods 244 along the circumferential direction, and the lower ends of the insertion rods 244 are pointed.

[0075] Specifically, during use, when the detection signal of the first probe 211 is interrupted, if the second probes 233 on both sides can still detect the signal, the electric push rod 242 is started, and the output end of the electric push rod 242 drives the steering wheel 243 to move downward, and the steering wheel 243 drives the insertion rod 244 to move downward. When the insertion rod 244 is fully inserted into the ground, the traveling mechanism 1 is lifted up, and the traveling mechanism 1 is separated from the ground. Then, the steering motor 241 is started, and the steering motor 241 rotates 90°, so that the traveling mechanism 1 rotates 90°, and then the electric push rod 242 is retracted, and the electric push rod 242 drives the insertion rod 244 to reset, so that the traveling mechanism 1 contacts the ground again, and then the traveling mechanism 1 is started again to continue detecting the bifurcation of the underground pipeline.

[0076] By setting the steering mechanism 24, the traveling mechanism 1 can be turned, and cooperate with the auxiliary detection member 23 to enable the traveling mechanism 1 to continue to detect the bifurcation of the underground pipeline, further improving the comprehensiveness of the underground pipeline detection.

[0077] Furthermore, the electric push rod 242 is a prior art and will not be described in detail.

[0078] like Figure 2 , 4 As shown, the traveling mechanism 1 includes a frame 11, the steering motor 241 is fixedly connected to the frame 11, and traveling members 12 are respectively provided at both ends of the frame 11. The traveling member 12 includes a traveling motor 121 fixedly connected to the frame 11, and the output ends on both sides of the traveling motor 121 are respectively fixedly connected to traveling shafts 122, and each traveling shaft 122 is fixedly connected to a traveling wheel 123.

[0079] Specifically, when in use, when the traveling mechanism 1 needs to move, the traveling motor 121 is started, the output end of the traveling motor 121 drives the traveling shaft 122 to rotate, and the traveling shaft 122 drives the traveling wheel 123 to rotate, so that the frame 11 moves, thereby making the detection mechanism 2 move.

[0080] Through the arrangement of the traveling mechanism 1 , the traveling motor 121 can drive the traveling wheel 123 to rotate, so that the frame 11 moves, and the frame 11 drives the detection mechanism 2 to detect the underground pipeline.

[0081] like Figure 5 , 10 As shown, the travel mechanism 1 also includes a pushing member 13 arranged on the frame 11, and the pushing member 13 includes two hinged forks 131 symmetrically fixedly connected to the frame 11, and each of the hinged forks 131 is rotatably connected to a connecting plate 132, and the ends of the two connecting plates 132 are fixedly connected to push rods 133, and a locking member 14 is arranged between the connecting plate 132 and the frame 11.

[0082] Specifically, in the initial state, the connecting plate 132 is parallel to the frame 11; when the detection device needs to be pushed, the locking member 14 is unlocked, the connecting plate 132 is rotated so that the connecting plate 132 is perpendicular to the frame 11, and then the push rod 133 is pushed to push the detection device to move.

[0083] By providing the pushing member 13 , the detection device can be pushed, thereby facilitating the movement of the detection device.

[0084] like Figure 5 , 7 As shown, the locking member 14 includes a fixed shaft 141 fixedly connected between the two connecting plates 132, a square sleeve 142 is fixedly sleeved on the fixed shaft 141, a rotating shaft 143 is rotatably connected to the frame 11, a torsion spring 144 is connected between the rotating shaft 143 and the frame 11, an L-shaped locking rod 145 is fixedly connected to the rotating shaft 143, and the lower side surface of the locking rod 145 is in contact with the top surface of the square sleeve 142.

[0085] Specifically, when in use, when it is necessary to flip the connecting plate 132, rotate the locking rod 145 so that the locking rod 145 drives the rotating shaft 143 to rotate 90°. At the same time, the rotating shaft 143 accumulates force on the torsion spring 144, and then flips the connecting plate 132. After the connecting plate 132 is flipped 90°, release the locking rod 145, so that the locking rod 145 is reset under the action of the torsion spring 144, limiting the rotation of the square sleeve 142, thereby locking the connecting plate 132, making it convenient for the user to push the push rod 133.

[0086] By setting the locking member 14, the connecting plate 132 can be locked, which facilitates the folding and pushing of the pushing member 13, makes it easier for users to use the device and improves the passability of the device in terms of height.
