Description

Technical Field

[0001] This application relates to the field of radar detection brackets, and in particular to adjustable radar detection brackets for detecting the burial depth of underground pipelines. Background Technology

[0002] Underground pipeline burial depth detection utilizes technologies such as ground-penetrating radar and electromagnetic induction to analyze the distribution characteristics of underground media by emitting specific signals and receiving reflected waves, thereby determining the spatial location and burial depth of pipelines. This process provides crucial data support for urban planning, construction, maintenance, and safety management, preventing excavation and damage accidents caused by unclear pipeline information. The detection support is an auxiliary device specifically designed to carry ground-penetrating radar equipment.

[0003] Traditional detection brackets are usually fixed structures with non-adjustable height, making them difficult to adapt to undulating terrain. This can easily lead to improper coupling distance between the radar antenna and the ground, causing signal attenuation or detection blind spots. When detecting pipelines in different directions or at an angle, frequent manual moving and coarse adjustments are required to change the detection direction, which is not only inefficient but also prone to introducing operational errors, affecting data consistency and detection accuracy. Utility Model Content

[0004] To address the issue of the difficulty in flexibly adjusting the height and angle of the radar antenna on the detection bracket, this application provides an adjustable radar detection bracket for detecting the burial depth of underground pipelines.

[0005] The adjustable radar detection bracket for underground pipeline burial depth detection provided in this application adopts the following technical solution:

[0006] An adjustable radar detection bracket for underground pipeline burial depth detection includes a ground-penetrating radar box and an adjustment mechanism at the top of the ground-penetrating radar box for adjusting the height and angle of the ground-penetrating radar box. The top and adjacent sides of the adjustment mechanism are respectively equipped with motor 1, motor 2, and motor 3, which provide driving force to the adjustment mechanism. The adjustment mechanism includes a fixed plate and a sleeve rod rotatably passing through the middle of the fixed plate. A sliding rod fixed to the drive end of motor 1 is slidably mounted inside the upper end of the sleeve rod. A limiting block is symmetrically fixed to the outer side of the sleeve rod near the sliding rod. A rotating bracket is slidably mounted between the two limiting blocks. A transmission rod 1 fixed to the output end of motor 2 is rotatably passed through the end of the rotating bracket away from the limiting blocks. A shaped rod 1 is fixedly mounted to the bottom end of the sleeve rod. A fixed rod 1 is fixedly passed through one side of the shaped rod 1. A spherical hinge pair is rotatably mounted to the end of the fixed rod 1 away from the shaped rod 1. A fixed rod 2 fixed to the ground-penetrating radar box is fixed to the bottom end of the spherical hinge pair.

[0007] By adopting the above technical solution, the rotational motion of the rotating bracket is converted into the longitudinal movement of the sleeve rod by the second motor, which is used to adjust the height of the ground penetrating radar box; the sliding rod and sleeve rod are rotated by the first motor, which, in conjunction with the linkage components below, is used to adjust the horizontal angle of the ground penetrating radar box; the pitch angle of the ground penetrating radar box is adjusted by the third motor driving the second irregular rod and the pitch tilt of the ground penetrating radar box; the bottom of the sleeve rod, the first irregular rod, is connected to the ground penetrating radar box through the first fixed rod, the spherical hinge pair and the second fixed rod. When each motor drives the adjustment mechanism, it is convenient to flexibly adjust the height and angle of the ground penetrating radar box, so as to meet the needs of different detection positions and attitudes of the radar when detecting the burial depth of underground pipelines, and improve the accuracy and comprehensiveness of the detection.

[0008] Preferably, a circular slider is symmetrically fixed inside one end of the rotating bracket near the limiting block, and the circular slider slides within the straight slide rail formed between the two limiting blocks.

[0009] By adopting the above technical solution, the circular sliders symmetrically arranged at one end of the rotating bracket near the limiting block are embedded in the straight slide between the two limiting blocks, so as to slide smoothly along the slide during adjustment and assist in the adjustment of the height of the ground penetrating radar box.

[0010] Preferably, the outer circumference of the slide rod is provided with a plurality of radial transmission key teeth, and the upper end of the sleeve rod is provided with a special-shaped groove adapted to the shape of the radial transmission key teeth, and the lower end of the slide rod slides in the special-shaped groove.

[0011] By adopting the above technical solution, the radial transmission key teeth distributed on the outer circumference of the slide rod cooperate with the irregular groove adapted to the upper end of the sleeve rod, so that the lower end of the slide rod slides in the irregular groove. Under the drive of motor two, a stable and precise linear lifting motion is achieved, which facilitates the height adjustment of the ground penetrating radar box. Under the drive of motor one, the lower linkage component is rotated, thereby realizing the horizontal angle adjustment of the ground penetrating radar box.

[0012] Preferably, a shaped rod 2 is fixedly sleeved on the outer side of the middle part of the fixed rod 2, and a transmission rod 2 is fixedly sleeved on the side of the shaped rod 2 away from the fixed rod 2. A fixed bracket fixed to the bottom end of the fixed plate is rotatably sleeved on the outer side of the transmission rod 2 near the shaped rod 2. The end of the transmission rod 2 away from the shaped rod 2 is fixed to the output end of the motor 3. A fixed disc fixed to the fixed end of the motor 3 is rotatably sleeved on the outer side of the transmission rod 2 near the motor 3. The side of the fixed disc near the fixed bracket is fixed to the side of the fixed bracket.

[0013] By adopting the above technical solution, the three motors drive the two transmission rods to rotate. One end of the transmission rod is limited by the rotation of the fixed bracket, and the other end is stably connected to the side of the fixed bracket via the fixed disc. The rotational power is converted into the tilting swing force of the irregular rod by the two fixed rods, so that the ground penetrating radar box can achieve pitch angle adjustment.

[0014] Preferably, the outer side of the adjustment mechanism is fitted with a housing, T-shaped sliders are symmetrically fixed on both sides of the fixing plate, and T-shaped grooves that slide and cooperate with the T-shaped sliders are symmetrically opened on both sides of the inner wall of the housing.

[0015] By adopting the above technical solution, the T-shaped sliding grooves on both sides of the inner wall of the outer housing of the adjustment mechanism slide in cooperation with the T-shaped sliders on both sides of the fixed plate, providing stable support and guidance for the adjustment mechanism.

[0016] Preferably, a plurality of adjusting rods are slidably arranged around the bottom of the housing, and each adjusting rod has a limiting hole at both its upper and lower ends. Threaded holes with the same diameter as the limiting holes are symmetrically opened on both sides of the lower end of the housing, and a limiting rod is threaded through the threaded hole and the corresponding limiting hole.

[0017] By adopting the above technical solution, the adjusting rod that is slidably set around the bottom of the shell, together with the limiting holes at its upper and lower ends and the threaded holes on both sides of the lower end of the shell, achieves positioning and fixation through the threaded penetration of the limiting rod, which facilitates the protection of the ground penetrating radar box and prevents ground debris from damaging the ground penetrating radar box.

[0018] Preferably, a control panel is provided at the top of the housing, and the control panel is electrically connected to the first motor, the second motor, the third motor and the ground-penetrating radar box.

[0019] By adopting the above technical solution, the control panel set at the top of the shell is electrically connected to motor one, motor two, motor three and the ground-penetrating radar box, which facilitates centralized control of the operation of each motor to achieve adjustment of the radar box height and angle, and improves the convenience of operation.

[0020] Preferably, a base plate is fixed to the bottom end of the plurality of adjusting rods, and rollers are symmetrically fixed to both sides of the base plate.

[0021] By adopting the above technical solution, the base plate and rollers work together to provide stable support and protection for the ground penetrating radar box, which facilitates its transfer between different detection locations and improves operational efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By driving the rotating bracket with motor 2, the rotational motion is converted into the longitudinal movement of the sleeve rod, which drives the fixed plate to rise and fall along the T-shaped sliding groove on the inner wall of the shell, thereby realizing the height adjustment of the ground penetrating radar box. By driving the sliding rod and sleeve rod with motor 1, the horizontal angle of the ground penetrating radar box is adjusted. By driving the irregular rod 2 and the ground penetrating radar box to tilt with motor 3, the pitch angle of the ground penetrating radar box is adjusted. This is conducive to quickly adapting to terrain undulations, maintaining the radar's optimal detection posture, and facilitating the expansion of single-point scanning coverage while the mobile base remains stationary. While keeping the phase center basically unchanged, in-situ spin is performed to quickly find the polarization angle with the strongest echo, effectively avoiding signal attenuation, detection blind spots, and manual handling errors, thereby improving operational efficiency and data accuracy.

[0024] 2. The housing provides storage space for the adjustment mechanism and the ground-penetrating radar box. The length and width of the ground-penetrating radar box are smaller than the length and width of the inner wall of the housing, allowing the ground-penetrating radar box to rotate within the housing's interior. Simultaneously, the adjustment bracket is a telescopic and foldable structure, and the adjustment rod can slide into a circular groove at the bottom of the housing. This allows the entire device to be easily stored inside the housing when not in operation, reducing its overall size and facilitating transportation and storage, thus improving the equipment's portability and ease of use.

[0038] The following is in conjunction with the appendix Figure 1 - Figure 8 This application will be described in further detail.

[0039] This application discloses an adjustable radar detection bracket for detecting the burial depth of underground pipelines.

[0040] Reference Figure 1 - Figure 3 , Figure 8 An adjustable radar detection bracket for underground pipeline burial depth detection includes a ground-penetrating radar box 1 and an adjustment mechanism 2 at the top of the ground-penetrating radar box 1 for adjusting its height and angle. A motor 4 is mounted at the top of the adjustment mechanism 2, providing driving force. Motors 5 and 6 are mounted on adjacent sides of the adjustment mechanism 2, also providing driving force. A housing 3 is fitted around the outside of the adjustment mechanism 2, providing storage space for the adjustment mechanism 2 and the ground-penetrating radar box 1. The length and width of the ground-penetrating radar box 1 are smaller than the length and width of the inner wall of the housing 3, so that the ground-penetrating radar box 1 can rotate in the internal space of the housing 3. Multiple adjusting rods 7 are slidably arranged around the bottom of the housing 3. Multiple vertically guiding circular grooves are opened around the bottom of the housing 3. The adjusting rods 7 slide in the circular grooves. Threaded holes 15 are symmetrically opened on both sides of the lower end of the housing 3. Limiting holes 14 are symmetrically opened at the upper and lower ends of the adjusting rods 7. The diameter of the limiting hole 14 is the same as the diameter of the threaded hole 15. A limiting rod 10 is provided through the internal threads of one of the limiting holes 14 and the threaded hole 15.

[0041] This device is suitable for on-site inspection of underground pipelines in the field. Before use, the device needs to be moved to the target position by the rollers 9 on the base plate 8. Adjust the sliding extension length of multiple adjustment rods 7 in the circular groove at the bottom of the housing 3 according to the ground conditions to keep the housing 3 horizontal and stable. Then, use the limit rod 10 threaded through the corresponding threaded hole 15 and the limit hole 14 to fix the adjustment rod 7. Subsequently, unfold the telescopic and foldable adjustment bracket 11 to assist in pushing the housing 3. Wirelessly connect motor 1 4, motor 2 5, motor 3 6 and ground penetrating radar box 1 through the control panel 12 to complete the installation preparation so that the adjustment mechanism 2 can subsequently adjust the height, rotation angle and pitch angle of the ground penetrating radar box 1.

[0042] The end of the limiting rod 10 near the housing 3 is threaded through the threaded hole 15. When the adjusting rod 7 slides to the required height, the adjusting rod 7 and the housing 3 can be fixed relative to each other by threading the limiting rod 10 through a threaded hole 15 and a limiting hole 14 aligned with the threaded hole 15. The bottom ends of the multiple adjusting rods 7 are fixed with a base plate 8. Rollers 9 are symmetrically fixed on both sides of the base plate 8. T-shaped grooves 13 are symmetrically opened on both sides of the inner wall of the housing 3. A telescopic and foldable adjusting bracket 11 is hinged to the outer side of the top of the housing 3. The adjusting bracket 11 is a linkage hinge structure. When not in use or during transportation, it can be folded and stored close to the outside of the housing (3). When in use, it can be unfolded and extended to a suitable length to act as a push rod or handle to assist the user in moving the entire bracket on the ground.

[0043] A control panel 12 is provided on the upper end of the adjustment bracket 11. The control panel 12 integrates a wireless communication module. Motor 1 4, Motor 2 5, Motor 3 6 and the ground-penetrating radar box 1 are all equipped with corresponding wireless receiving modules. The control panel 12 establishes a wireless communication connection with the wireless receiving modules of each motor and the ground-penetrating radar box 1 through the wireless communication module, forming a wireless control network. It sends control commands to each motor through the wireless network to adjust the opening and closing, direction and speed. At the same time, it receives the detection data wirelessly transmitted from the ground-penetrating radar box 1 and displays and processes it.

[0044] In use, the control system built into the control panel 12 wirelessly sends commands to control the opening and closing of motor 4, motor 5 and motor 6, so that the adjustment mechanism 2 drives the ground penetrating radar box 1 to make precise adjustments to the height, rotation angle and pitch angle, thereby enabling the ground penetrating radar box 1 to be aimed at the underground target pipeline area to collect burial depth data, and feed it back to the control panel 12 for processing in real time.

[0045] Reference Figure 4 - Figure 7The adjusting mechanism 2 includes a fixed plate 201 and a sleeve rod 202 rotatably passing through the middle of the fixed plate 201. The fixed plate 201 is located directly above the base plate 8. When the base plate 8 is retracted, it facilitates the storage and protection of the fixed plate 201. T-shaped sliders 216 are symmetrically fixed on both sides of the fixed plate 201. The shape of the T-shaped sliders 216 matches the shape of the T-shaped grooves 13. The fixed plate 201 slides up and down along the inner wall of the housing 3 through the sliding engagement of the T-shaped sliders 216 on both sides with the T-shaped grooves 13 on the inner wall of the housing 3. The upper end of the sleeve rod 202 is slidably provided with a slide rod 204. Multiple radial transmission teeth are distributed on the outer circumference of the slide rod 204. The shape of the slide rod 204 is as follows: Figure 7 As shown, the upper end of the sleeve rod 202 is provided with a special-shaped groove 223. The shape of the special-shaped groove 223 is adapted to the shape of the slide rod 204. The lower end of the slide rod 204 slides in the special-shaped groove 223. The top end of the slide rod 204 is fixed to the output end of the motor 4. The fixed end of the motor 4 is fixed to the middle of the inner top surface of the housing 3. A limiting block 203 is symmetrically fixed on the outer side of the sleeve rod 202 near the slide rod 204. The limiting block 203 is located above the fixing plate 201. The two limiting blocks 203 are parallel to each other and spaced apart. The gap between them forms a straight slide.

[0046] When the height of the ground-penetrating radar box 1 needs to be adjusted, the motor 25 is started to drive the transmission rod 207 to rotate, which in turn drives the rotating bracket 205 to rotate around the transmission rod 207. The rotating bracket 205 moves within the slide rail formed by the limiting block 203 through the circular slider 206 at its end, converting the rotational motion into the longitudinal movement of the sleeve rod 202. The sleeve rod 202 drives the fixing plate 201 to slide longitudinally along the T-shaped slide groove 13 of the housing 3 through the T-shaped slider 216, which in turn drives the irregular rod 208 and the spherical hinge pair 210 and the fixing rod 212 connected below to rise and fall synchronously, thereby adjusting the load-bearing height of the ground-penetrating radar box 1.

[0047] A circular hole 217 is provided in the middle of the limiting block 203. One end of the sleeve rod 202 near the slide rod 204 is fixedly inserted through the circular hole 217. A rotating bracket 205 is slidably arranged between the two limiting blocks 203. The shape of the rotating bracket 205 is as follows: Figure 6As shown, a circular slider 206 is symmetrically fixed inside the rotating bracket 205 near the limiting block 203. The diameter of the circular slider 206 matches the width of the straight slide rail formed between the two limiting blocks 203, allowing the circular slider 206 to slide within the slide rail. A transmission rod 207 is rotatably inserted through the rotating bracket 205 away from the limiting block 203. A circular hole 218 is opened at the end of the rotating bracket 205 near the transmission rod 207. The diameter is the same as that of the transmission rod 207. The transmission rod 207 is fixedly inserted through the circular hole 218. One end of the transmission rod 207 located outside the rotating bracket 205 is fixed to the output end of the motor 5. A fixing block 16 is fixedly installed at the fixed end of the motor 5. The end of the fixing block 16 away from the motor 5 is fixed to one side of the inner wall of the housing 3. The bottom end of the sleeve rod 202 is fixedly fitted with a special-shaped rod 208. The special-shaped rod 208 is a three-fold block. The shape of the special-shaped rod 208 is as follows: Figure 4 As shown, a circular hole 219 is provided in the middle of the upper end of the irregular rod 208, and the lower end of the sleeve rod 202 is fixedly inserted through the circular hole 219.

[0048] When it is necessary to adjust the rotation angle of the ground penetrating radar box 1, the motor 4 is started to drive the slide rod 204 to rotate. The slide rod 204 transmits the rotational force to the sleeve rod 202 through the cooperation of the radial transmission key teeth and the irregular sliding groove 223 at the upper end of the sleeve rod 202. This causes the sleeve rod 202, the irregular rod 208, and the spherical hinge pair 210 and the fixed rod 212 connected below to rotate as a whole around the axis of the sleeve rod 202, thereby enabling the ground penetrating radar box 1 to achieve horizontal rotation angle adjustment.

[0049] A fixing rod 209 is fixedly installed through one side of the irregular rod 208. A spherical hinge pair 210 is rotatably fitted onto the end of the fixing rod 209 away from the irregular rod 208. The spherical hinge pair 210 is spherical in shape. A semi-circular groove 220 is formed on the side of the spherical hinge pair 210 near the fixing rod 209. A circular hole is formed on one side of the inner wall of the semi-circular groove 220. The end of the fixing rod 209 away from the irregular rod 208 extends into the semi-circular groove 220. It is rotatably connected to the circular hole opened in the side wall of the semi-circular groove 220. The bottom end of the spherical hinge pair 210 is fixedly provided with a fixing rod 212. The outer side of the middle part of the fixing rod 212 is fixedly sleeved with a non-shaped rod 211. The shape and size of the non-shaped rod 211 are the same as the shape and size of the non-shaped rod 208. The circular hole 3 219 is diagonally symmetrical with the non-shaped rod 211. The side of the non-shaped rod 211 away from the fixing rod 212 is fixedly provided with a transmission rod 214.

[0050] A fixed bracket 213 is rotatably sleeved on the outer side of the end of the transmission rod 214 near the irregular rod 211. A circular hole 221 is opened at the lower end of the fixed bracket 213. The end of the transmission rod 214 near the irregular rod 211 rotates through the circular hole 221. The end of the transmission rod 214 away from the irregular rod 211 is fixed to the output end of the motor 6. A fixed disc 215 is rotatably sleeved on the outer side of the end of the transmission rod 214 near the motor 6. A circular hole 222 is opened in the middle of the fixed disc 215. The end of the transmission rod 214 near the motor 6 rotates through the circular hole 222. The side of the fixed disc 215 near the fixed bracket 213 is fixed to the side of the fixed bracket 213. The fixed end of the motor 6 is fixed to the surface of the fixed disc 215 away from the fixed bracket 213.

[0051] When it is necessary to adjust the pitch angle of the ground penetrating radar box 1, the motor 6 is started to drive the transmission rod 214 to rotate, which in turn causes the irregular rod 211 to swing around the transmission rod 214. The swing of the irregular rod 211 is transmitted to the spherical hinge pair 210 and the ground penetrating radar box 1 through the fixed rod 212, thereby causing the ground penetrating radar box 1 to perform pitch movement. At the same time, the spherical hinge pair 210 rotates around the fixed rod 209. Since the irregular rod 208 is fixedly sleeved at the bottom of the sleeve rod 202, the pitch angle of the ground penetrating radar box 1 can be adjusted.

[0052] The implementation principle of the adjustable radar detection bracket for underground pipeline burial depth detection in this application embodiment is as follows: When the device is in use, the control panel 12 wirelessly sends commands to drive the rotating bracket 205 through the starter motor 2 5, so that the sleeve rod 202 drives the fixed plate 201 to rise and fall along the T-shaped slide groove 13 of the housing 3, thereby realizing the height adjustment of the ground penetrating radar box 1. The starter motor 4 drives the slide rod 204, and through the cooperation of the radial transmission key teeth and the irregular slide groove 223, the sleeve rod 202 and the linkage components below rotate as a whole, thereby realizing the horizontal angle adjustment of the ground penetrating radar box 1. The starter motor 3 drives the irregular rod 211 and the ground penetrating radar box 1 to tilt, thereby realizing the tilt angle adjustment of the ground penetrating radar box 1, so that the ground penetrating radar box 1 can accurately align with the target area to collect data and feed it back to the control panel 12 in real time.

[0053] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art.
