Underground pipeline detection device

Abstract

The utility model relates to the technical field of pipeline detection, and discloses an underground pipeline detection device which comprises a rectangular plate, a rotating shaft, a supporting block, a mounting block, a gear motor, wheels, universal wheels, a hook, a detector and an elastic piece. During use, after the detector is hung on the four-corner hooks, the two-corner gear motors are controlled to work, so that the two-corner wheels can be driven to rotate, and the two-corner wheels are matched with the two-corner universal wheels to work, so that the device can be driven to move. Therefore, measuring personnel do not need to manually push the device to move, and physical output of the measuring personnel is reduced. Moreover, under the driving of external force, the two-angle rotating shafts can rotate relative to the rectangular plate, and then the two-angle supporting blocks are driven to rotate around the two-angle rotating shafts correspondingly. And finally, the wheels at the two corners can be driven to rotate around the two corners, so that the driving direction of the device is automatically changed. Meanwhile, in the running process of the device, the elastic pieces at the two corners can play a role in buffering and damping, and therefore the impact force borne by the detector is reduced.

[0017] The underground pipeline detection device provided in this disclosure can achieve the following technical effects:

[0018] This disclosure provides an underground pipeline detection device, including a rectangular plate, rotating shafts, support blocks, mounting blocks, geared motors, wheels, casters, hooks, a detector, and elastic elements. The rectangular plate includes rectangular holes, employing an open-hole design to reduce the overall weight of the rectangular plate and facilitate cable routing. Rotating shafts are rotatably installed at two adjacent corners of the rectangular plate, with the axes of both shafts perpendicular to the plane of the rectangular plate, allowing for rotational movement relative to the plate. Support blocks are installed at the bottom ends of the two corner rotating shafts, rotating under their influence. Mounting blocks are located below the two corner support blocks, supporting the geared motors. Geared motors are mounted on the two corner mounting blocks, with the axes of their rotating ends parallel to the plane of the rectangular plate, providing driving force for rotational movement. Wheels are installed at the rotating ends of the two corner geared motors, rotating under their influence. Casters are installed at the other two corners of the rectangular plate's bottom surface, providing contact with the ground. Hooks are installed at the four corners of the bottom surface of the rectangular plate to secure the detector. The detector is suspended from the four corner hooks for detecting pipelines. Elastic elements are installed between the two corner support blocks and the two corner mounting blocks to provide cushioning and shock absorption. The two corner pivots are controllable and can rotate relative to the rectangular plate to change the orientation of the corner wheels.

[0019] This disclosure provides an underground pipeline detection device that uses hooks to fix the detector, offering advantages such as simple structure and ease of assembly and disassembly. After suspending the detector on the four corner hooks, controlling the two corner reduction motors drives the two corner wheels to rotate. These, in conjunction with the two corner casters, move the device. Therefore, manual pushing by the surveyor is unnecessary, reducing physical exertion. Furthermore, under external force, the two corner shafts rotate relative to the rectangular plate, causing the two corner support blocks to rotate around the two corner shafts. This ultimately drives the two corner wheels to rotate around the two corners, automatically changing the device's direction of travel. Simultaneously, during travel, the elastic elements at the two corners act as buffers and shock absorbers, reducing the impact force on the detector.

[0036] Combination Figures 1 to 4As shown, this embodiment of the present disclosure provides an underground pipeline detection device, including a rectangular plate 1, a rotating shaft 2, a support block 3, a mounting block 4, a reduction motor 5, wheels 6, casters 7, hooks 8, a detector 9, and elastic elements. The rectangular plate 1 includes rectangular holes, employing an open-hole design to reduce the overall weight of the rectangular plate 1 and to facilitate cable routing. The rotating shaft 2 is rotatably installed at two adjacent corners of the rectangular plate 1, with the axes of both corner shafts perpendicular to the plane of the rectangular plate 1, allowing for rotational movement relative to the rectangular plate 1. The support blocks 3 are respectively installed at the bottom ends of the two corner shafts 2, rotating under the drive of the two corner shafts 2. The mounting blocks 4 are located below the two corner support blocks 3, supporting the installation of the reduction motors 5. The reduction motors 5 are respectively installed on the two corner mounting blocks 4, with the axes of the rotating ends of the two corner reduction motors 5 parallel to the plane of the rectangular plate 1, providing driving force for rotational movement. The wheels 6 are respectively installed on the rotating ends of the two corner reduction motors 5, rotating under the drive of the two corner reduction motors 5. The casters 7 are installed at the other two corners of the bottom surface of the rectangular plate 1, respectively, for contact with the ground. Hooks 8 are installed at the four corners of the bottom surface of the rectangular plate 1 for fixing the detector 9. The detector 9 is suspended from the four corner hooks 8 for detecting pipelines. Elastic elements are installed between the two corner support blocks 3 and the two corner mounting blocks 4, respectively, for buffering and shock absorption. The two corner pivots 2 are controllable and can rotate relative to the rectangular plate 1 to change the orientation of the two corner wheels 6.

[0037] This disclosure provides an underground pipeline detection device that uses hooks 8 to fix the detector 9, offering advantages such as simple structure and ease of assembly and disassembly. After suspending the detector 9 on the four corner hooks 8, controlling the two corner reduction motors 5 drives the two corner wheels 6 to rotate. These, in conjunction with the two corner casters 7, move the device. Therefore, manual pushing by the surveyor is unnecessary, reducing physical exertion. Furthermore, under external force, the two corner shafts 2 rotate relative to the rectangular plate 1, thereby causing the two corner support blocks 3 to rotate around the two corner shafts 2. This ultimately drives the two corner wheels 6 to rotate around the two corners, automatically changing the device's direction of travel. Simultaneously, during the device's movement, the elastic elements at the two corners act as buffers and shock absorbers, reducing the impact force on the detector 9.

[0038] Optionally, combined Figures 1 to 4As shown, the elastic element includes a guide shaft 10, a retaining ring 11, and a spring 12. The guide shaft 10 is slidably mounted on the two corner support blocks 3 along the axial direction of the two corner pivots 2. The bottom ends of the two corner guide shafts 10 are connected to the two corner mounting blocks 4, both serving as guides and supports. The retaining rings 11 are respectively mounted on the top ends of the two corner guide shafts 10, both serving as limiters to prevent the two corner guide shafts 10 from falling off the two corner support blocks 3. The springs 12 are respectively fitted onto the two corner guide shafts 10 and located between the two corner support blocks 3 and the two corner mounting blocks 4, both serving as buffers.

[0039] In this embodiment, both corner springs 12 serve as buffers. When the device travels on bumpy roads, the two corner guide shafts 10 can slide relative to the two corner support blocks 3 respectively. This compresses the two corner springs 12, thereby absorbing energy and reducing the impact force.

[0040] Optionally, combined Figures 1 to 4 As shown, the elastic element also includes metal bushings 13. The metal bushings 13 are respectively fitted onto the two corner guide shafts 10 and respectively installed on the two corner support blocks 3.

[0041] In this embodiment, the elastic element further includes metal bushings 13 that are respectively fitted onto the two corner guide shafts 10 and respectively mounted on the two corner support blocks 3. The two corner metal bushings 13 are used to reduce the friction between the two corner guide shafts 10 and the two corner support blocks 3, and to improve the accuracy of the two corner guide shafts 10 when sliding relative to the two corner support blocks 3.

[0042] Optionally, combined Figures 1 to 4 As shown, the elastic element also includes metal washers 14. The metal washers 14 are respectively fitted onto the two corner guide shafts 10 and are located at the contact points between the two corner springs 12 and the two corner metal bushings 13 and the two corner mounting blocks 4.

[0043] In this embodiment, the elastic element further includes metal washers 14 respectively fitted onto the two corner guide shafts 10. The two corner metal washers 14 are located at the contact points between the two corner springs 12 and the two corner metal bushings 13 and the two corner mounting blocks 4, respectively, to prevent the surfaces of the two corner metal bushings 13 and the two corner mounting blocks 4 from being worn and damaged by the two corner springs 12.

[0044] Optionally, combined Figure 3 As shown, the elastic element also includes shock-absorbing rubber 15. The shock-absorbing rubber 15 is respectively installed between the opposite surfaces of the two corner support blocks 3 and the two corner mounting blocks 4.

[0045] In this embodiment, the elastic element further includes shock-absorbing rubber 15 installed between the opposing surfaces of the two corner support blocks 3 and the two corner mounting blocks 4. Both corner shock-absorbing rubbers 15 serve to dampen vibrations and suppress the jumping of the two corner springs 12.

[0046] Optionally, combined Figure 1 and Figure 4 As shown, it also includes a motor mounting plate 16 and a drive motor 17. The motor mounting plate 16 is mounted on the top surface of the rectangular plate 1 to support and mount the drive motor 17. The drive motor 17 is mounted on the motor mounting plate 16 to provide driving force to achieve the rotational motion function. Under the drive of the drive motor 17, the two corner shafts 2 rotate relative to the rectangular plate 1.

[0047] In this embodiment, the two corner shafts 2 rotate relative to the rectangular plate 1 under the drive of the drive motor 17. Using the drive motor 17 as the power source has advantages such as stable motion and convenient control.

[0048] Optionally, combined Figure 1 and Figure 4 As shown, it also includes a driving belt gear, a driven belt gear, and a synchronous toothed belt 18. The driving belt gear is mounted on the rotating end of the drive motor 17 and rotates under the drive of the drive motor 17. The driven belt gears are respectively mounted on the top ends of the two angular rotating shafts 2, and are used to drive the two angular rotating shafts 2 to rotate. The synchronous toothed belt 18 is fitted between the driving belt gear and the two angular driven belt gears to transmit driving force. The driving belt gear and the two angular driven belt gears are arranged in a triangular pattern.

[0049] In this embodiment, controlling the drive motor 17 to operate drives the driving gear to rotate. The synchronous toothed belt 18 then drives the two driven gears at the corners to rotate. This, in turn, drives the two corner shafts 2 to rotate, ultimately changing the orientation of the two corner wheels 6. Furthermore, the triangular arrangement of the driving gear and the two driven gears at the corners ensures a stable transmission by maintaining the wrap angle between the driving gear, the two driven gears at the corners, and the synchronous toothed belt 18.

[0050] Optionally, combined Figure 3 As shown, it also includes bearing housings 19 and angular contact ball bearings. The bearing housings 19 are mounted on the rectangular plate 1 and respectively fitted onto the two angular shafts 2. The angular contact ball bearings are respectively mounted between the two angular bearing housings 19 and the two angular shafts 2.

[0051] In this embodiment, two angular bearing seats 19 are respectively installed on two rectangular plates 1 at the corners, and are used to support and install angular contact ball bearings. The two angular contact ball bearings installed opposite each other at the corners are used to support and install two angular rotating shafts 2, so as to reduce the frictional force on the two angular rotating shafts 2 and improve the rotational accuracy of the two angular rotating shafts 2.

[0052] Optionally, combined Figure 1 and Figure 4 As shown, it also includes a pusher 20. The pusher 20 is mounted on the top surface of the rectangular plate 1.

[0053] In this embodiment, a pusher 20 is also included, mounted on the top surface of the rectangular plate 1. The pusher 20 is for gripping, so as to facilitate manual movement of the entire device.

[0054] Optionally, combined Figure 1 and Figure 4 As shown, it also includes a display controller 21. The display controller 21 is mounted on the top surface of the rectangular plate 1.

[0055] In this embodiment, a display controller 21 is also included, which is mounted on the top surface of the rectangular plate 1. The display controller 21 is electrically connected to the detector 9 and is used to display the working status of the detector 9 and control the operation of the detector 9.

[0057] In this embodiment, an antenna 22 is also included, which is mounted on the top surface of the rectangular plate 1. The antenna 22 is electrically connected to the display controller 21 and is used to transmit and receive signals.
