DETAILED DESCRIPTION

[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] In addition, the term "and / or" in this paper is only a description of the association relationship of the associated objects, which means that there can be three kinds of relationships, for example, A and / or B, which can represent the three cases of existence of A alone, existence of A and B simultaneously, and existence of B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are in an "or" relationship.

[0032] For example, Figures 1 to 6As shown, the underground pipeline comprehensive planning multi-dimensional data acquisition device, the structural components include two first side plates 4 arranged oppositely, two second side plates 5 arranged correspondingly, a second adjusting mechanism 7 for supporting, a geological radar module 10 for detecting the underground geological structure and pipeline distribution on the first adjusting mechanism 6, an electromagnetic induction module 9 capable of sensing the electromagnetic signal of the underground metal pipeline, and an ultrasonic detection module 14 capable of detecting the depth and defects of the underground pipeline. Two first side plates 4 and two second side plates 5 are connected in a head-to-tail manner, thereby forming a stable rectangular frame structure to provide a basic support structure for the entire acquisition device. The second adjusting mechanism 7 is arranged on the two first side plates 4, and the first adjusting mechanism 6 is arranged on the second adjusting mechanism 7, forming a nested linkage structure. The first adjusting mechanism 6 as a direct drive component can drive the geological radar module 10, the electromagnetic induction module 9 and the ultrasonic detection module 14 to move along the predetermined track, realizing multi-dimensional acquisition of underground pipeline data in different directions and depths.

[0033] In actual use, the first adjusting mechanism 6 can drive the geological radar module 10, the electromagnetic induction module 9 and the ultrasonic detection module 14 to move in a predetermined direction, realizing the adjustment of the positions of the geological radar module 10, the electromagnetic induction module 9 and the ultrasonic detection module 14. At the same time, the second adjusting mechanism 7 can control the first adjusting mechanism 6 to move along the direction of the second adjusting mechanism 7. By setting the first adjusting mechanism 6 and the second adjusting mechanism 7, when the user moves the acquisition device to the pipeline position, it is no longer necessary to frequently move the acquisition device to meet the measurement environment of the geological radar module 10, the electromagnetic induction module 9 and the ultrasonic detection module 14. Only the first adjusting mechanism 6 and the second adjusting mechanism 7 need to be controlled, reducing the workload of the user when measuring multiple pipeline positions and improving work efficiency. And the first adjusting mechanism 6 and the second adjusting mechanism 7 which can be adjusted in two perpendicular directions also facilitate the user to find the measurement position of the geological radar module 10, the electromagnetic induction module 9 and the ultrasonic detection module 14, saving measurement time.

[0034] The basic working principle of the geological radar module 10 is as follows: electromagnetic wave emission: GPR emits high-frequency electromagnetic waves (in the range of tens of MHz to several GHz) through an antenna. These electromagnetic waves penetrate the ground and are reflected by underground objects (such as metal pipes or rock layers). Echo reception: the receiver of the GPR receives the echo signal reflected from the underground object. Signal processing: after processing the received echo signal, the properties, depth, position, etc. of the object are analyzed according to the intensity, time delay and frequency change of the reflected wave.

[0035] The basic working principle of the electromagnetic induction module 9 is as follows: electromagnetic induction: the electromagnetic induction module induces the magnetic field signal generated by the underground metal pipeline by transmitting low-frequency electromagnetic fields to the underground. Change detection: when electromagnetic waves encounter metal objects, a magnetic field change will occur on the surface of the object. The device detects these changes to determine the path of the pipeline. Signal strength analysis: through the change in the induced magnetic field strength, the device can calculate the position, shape, and direction of the metal pipeline. Features: suitable for metal objects: especially suitable for detecting metal pipelines, metal cables, etc.

[0036] The basic working principle of the ultrasonic detection module 14 is as follows: ultrasonic wave propagation: the module transmits high-frequency ultrasonic signals to the underground pipeline or structure, and then receives the returned echo signals. Echo analysis: according to the time delay and intensity change of the echo signal, the thickness, crack location, corrosion degree, and other information of the pipeline can be calculated. Signal processing: the echo time and reflection intensity of the ultrasonic signal are transmitted to the processor for analysis, thereby providing accurate underground pipeline health status.

[0037] Further, the underground pipeline comprehensive planning multi-dimensional data acquisition device also includes a processor, and the ground penetrating radar module 10, the electromagnetic induction module 9, and the ultrasonic detection module 14 transmit raw data to the processor. The processor performs real-time processing, analysis, and fusion of the data. The processed data is transmitted to the terminal device through a wireless network. Through this integrated multi-dimensional detection technology and efficient data transmission, users can obtain comprehensive information about underground pipelines in real time, make timely decisions, and perform maintenance and management.

[0038] The working principles of the processor, the ground penetrating radar module 10, the electromagnetic induction module 9, and the ultrasonic detection module 14 described above are well known to those skilled in the art, and specific working principles and implementation methods are not described here.

[0039] In the present embodiment, the second adjusting mechanism 7 is responsible for driving the first adjusting mechanism 6 to move, and the second adjusting mechanism 7 and the first adjusting mechanism 6 are in a perpendicular spatial layout relationship with each other in the moving direction.

[0040] In actual use, the perpendicular driving design of the second adjusting mechanism 7 and the first adjusting mechanism 6 enables the ground penetrating radar module 10, the electromagnetic induction module 9, and the ultrasonic detection module 14 to cover a wider working area, making it easier for users to find the measurement position of the underground pipeline.

[0041] In the embodiment, in order to further improve the functionality and stability of the underground pipeline comprehensive planning multi-dimensional data acquisition device, a series of key components are added. Specifically, it covers four back plates 2, four sliding grooves 12, four circular wheels 3 and four limit blocks 13. In terms of structural connection, two first side plates 4 are respectively connected to one corresponding limit block 13, that is, one first side plate 4 is connected to two limit blocks 13. Four sliding grooves 12 are machined on four back plates 2, and the sliding groove 12 and the limit block 13 can slide, the sliding groove 12 limits the limit block 13 to move only in the vertical direction, and the shape of the sliding groove 12 and the limit block 13 is matched.

[0042] In actual use, the ground penetrating radar module 10, the electromagnetic induction module 9 and the ultrasonic detection module 14 can move up and down relative to the back plate 2. With this function, when facing complex and variable underground pipeline distribution scenarios and diversified detection depth requirements, the ground penetrating radar module 10, the electromagnetic induction module 9 and the ultrasonic detection module 14 can adjust their vertical height positions, making it more convenient for users to focus on pipeline information capture at different stratum depths, improving the pertinence and accuracy of data acquisition, and providing accurate data support for underground pipeline comprehensive planning work.

[0043] In the embodiment, in order to continuously optimize the structural integrity and functionality of the underground pipeline comprehensive planning multi-dimensional data acquisition device, a group of key structures are introduced, including two plate bodies 1, two limit racks 15, a first connecting piece 16 and a second connecting piece 17. Two plate bodies 1 are connected to two back plates 2, and two plate bodies 1 further strengthen the lateral support strength of the device, making the entire frame structure more stable. The plate body 1 cooperates with the limit rack 15, and the second side plate 5 can slide on the limit rack 15. The first connecting piece 16 is connected between the two second side plates 5, and the first connecting piece 16 is connected to the second connecting piece 17 through bolts, and the second connecting piece 17 is connected to the two first side plates 4.

[0044] In actual use, the first connecting piece 16 and the second connecting piece 17 arranged on the first side plate 4 and the second side plate 5 not only improve the compressive strength of the first side plate 4 and the second side plate 5, but also the protruding first connecting piece 16 and the second connecting piece 17 make it more convenient for users to indirectly grasp the first side plate 4 and the second side plate 5 to change the height of the first side plate 4 and the second side plate 5 structure.

[0045] In the embodiment, in order to further improve the operation and stability of the underground pipeline comprehensive planning multi-dimensional data acquisition device, a positioning mechanism 8 is additionally arranged.

The clamping part 804 and the clamping piece 805 form a clamping matching relationship, and the clamping piece 805 is connected with the second side plate 5. At the same time, the tension spring 806 is connected between the limiting frame 15 and the rotating plate 803. By virtue of the elastic tension characteristics of the tension spring 806, on one hand, the tension spring 806 provides power assistance for the rotation reset of the rotating plate 803, and on the other hand, ensures that the rotating plate 803 can return to the original state after dynamic adjustment, i.e., the clamping part 804 on the rotating plate 803 is clamped into the clamping piece 805.

[0046] In actual use, when the user needs to adjust the height of the ground penetrating radar module 10, the electromagnetic induction module 9 and the ultrasonic detection module 14, the rotating plate 803 can be rotated first, at this time, the tension spring 806 is stretched, so that the clamping part 804 on the rotating plate 803 is separated from the clamping piece 805, then the user can lift the second side plate 5 upwards, and when reaching a suitable measurement position, the rotating plate 803 can be released, at this time, the tension spring 806 loses external force support to drive the clamping part 804 on the rotating plate 803 to be clamped into the clamping piece 805 for positioning, so as to realize the positioning of the height of the ground penetrating radar module 10, the electromagnetic induction module 9 and the ultrasonic detection module 14. The whole operation process is simple and fast, and the work efficiency is improved.

[0047] In the embodiment, the handle 11 is connected to one of the plate bodies 1, and the position of the handle 11 corresponds to the position of the positioning mechanism 8. The positioning mechanism 8 further comprises a foot pedal 802, and the lower portion of the rotating plate 803 is connected with the foot pedal 802.

[0048] In actual use, the user can hold the handle 11 to push the acquisition device to move, and at the same time, the user can step on the foot pedal 802 to drive the rotating plate 803 to rotate, which is more convenient for the user to operate.

[0049] In the embodiment, the second adjusting mechanism 7 comprises an electric sliding block 701 and a sliding rail 702. The electric sliding block 701 is slidably connected with the sliding rail 702, and the electric sliding block 701 can move on the sliding rail 702.

[0050] In actual use, the electric sliding block 701 can move along the setting direction of the sliding rail 702, and the electric sliding block 701 can drive the first adjusting mechanism 6 to move in the process of movement.

[0051] In the embodiment, the first adjusting mechanism 6 comprises a bottom plate 601, a cushion plate 606, a motor 602, a sliding block 603, a screw rod 604 and a sliding rod 605. The ground penetrating radar module 10, the electromagnetic induction module 9 and the ultrasonic detection module 14 are connected to the bottom plate 601, the cushion plate 606 is connected to the motor 602, the output end of the motor 602 is connected to the screw rod 604, the screw rod 604 is threadedly connected to the sliding block 603, the screw rod 604 is rotationally connected to the cushion plate 606 through a bearing, and the sliding block 603 can slide on the sliding rod 605.

The sliding block 603 is connected to the bottom plate 601, and the cushion plate 606 is connected to the electric sliding block 701.

[0052] In actual use, the user can start the motor 602, the motor 602 can drive the screw rod 604 to rotate, the screw rod 604 can drive the sliding block 603 to move in the process of rotation, since the sliding block 603 is limited to straight-line movement by the sliding rod 605 at this time, the sliding block 603 can drive the bottom plate 601 to move in a straight line at this time, and can synchronously drive the ground penetrating radar module 10, the electromagnetic induction module 9 and the ultrasonic detection module 14 to move, so as to realize the adjustment of the positions of the ground penetrating radar module 10, the electromagnetic induction module 9 and the ultrasonic detection module 14.
