Description

Technical Field

[0001] The utility model relates to the technical field of radar platforms, and in particular to a radar mobile platform for three-dimensional measurement of geological deformation. Background Art

[0002] In the field of geological disaster prevention and control, three-dimensional monitoring of mountain deformation is a crucial technical tool for assessing geological stability and providing early warning of disasters such as landslides. Currently, a common measurement method involves deploying radar equipment on an opposing mountain with a low or relatively stable deformation trend to perform non-contact surface deformation measurements of the target mountain. Through long-range, high-precision micro-displacement detection, dynamic monitoring of the mountain's overall deformation characteristics and risk assessment can be achieved.

[0003] However, in actual measurements, the target mountain's surface environment is complex and variable, often with numerous obstructions that severely impact radar observations. For example, the mountain's surface is often covered with tall, dense vegetation, irregularly distributed large rocks, rockfall accumulations, and even new landslides generated by natural weathering or small-scale geological activity. These obstructions not only block the normal propagation of radar signals, resulting in missing echoes in the target area, but also easily create monitoring blind spots, preventing the effective identification and capture of certain key deformation areas, reducing the integrity and accuracy of monitoring results.

DETAILED DESCRIPTION

[0028] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0030] Example

[0031] The following reference Figures 1-4 As shown, and further described in conjunction with specific embodiments, this embodiment provides a radar mobile platform for three-dimensional geological deformation measurement, comprising a track frame 1 fixedly mounted on a mountain; a base 2 slidably mounted on track frame 1, and a first drive member 21 mounted on base 2 for driving base 2 to move along track frame 1 and secure it to any position. The provision of base 2 movable along track frame 1 enables the radar monitoring equipment to flexibly switch between multiple measurement locations on the mountain surface, facilitating the acquisition of geological deformation data at different measurement points, improving measurement range and efficiency, and resolving the issue of blind spots in a single viewing angle caused by obstructions.

[0032] Reference Figure 2 and Figure 3 As shown, the turntable 3 is rotatably mounted on the base 2. Mounted on the base 2 is a second drive member 31 for driving the turntable 3 vertically and securing it to any desired position. This second drive member 31 includes a second drive motor with a vertically mounted rotation axis. This self-locking motor allows the turntable 3 to precisely steer according to the relative orientation of the target area. Combined with the self-locking function, it ensures stability at the set angle, preventing deviation and providing a stable observation reference for the radar equipment.

[0033] A pair of swing arms 4 are provided, and one end of the pair of swing arms 4 is hingedly mounted on the turntable 3 at the same time, and the hinge direction thereof is parallel to the plane where the turntable 3 is located. A pair of radar bodies 5 are correspondingly mounted on the other ends of the pair of swing arms 4. The swing arms 4 are telescopically arranged and can fix their length after telescoping. A third driving member 41 is provided on the turntable 3 for driving the pair of swing arms 4 to swing synchronously and fix them to the position after swinging. Among them, the third driving member 41 includes a third driving motor, and the third driving motor is a self-locking motor. Through the synchronous swing design of the swing arms 4, the radar coverage of areas with different elevation angles can be achieved, and the telescopic structure of the swing arm further adjusts the relative distance between the radar body 5 and the target surface, thereby improving the imaging accuracy and target recognition rate.

[0034] Reference Figure 2 Specifically, the track frame 1 includes a guide rail 11, which is an I-beam structure. Other shapes, such as a T-shape or other anti-slip configurations, are also possible. The guide rail 11 can be spliced ​​to desired lengths or installed in a curved shape to match the curvature of the mountain. This design enhances the track's ability to adapt to complex mountain terrain, ensuring smooth movement and precise positioning of the platform at varying heights and curvatures.

[0035] Track frame 1 comprises multiple columns 12, the tops of which are fixedly connected to guide rails 11 via clamps 13 and bolts. Columns 12 and guide rails 11 can also be welded together, while the bottoms of columns 12 are fixed to the ground. The specific installation method of columns 12 can be customized based on the mountain topography. For example, a pre-excavated pit can be constructed on the slope, concrete piers can be poured to enhance stability, and then the columns 12 can be securely connected using bolts and other fasteners. This structure effectively enhances the overall stability and safety of track frame 1 in harsh terrain, preventing equipment tipping or displacement during monitoring.

[0036] The first drive member 21 comprises multiple pairs of rollers 22, which are simultaneously rotated and engaged with the guide rail 11. At least one of the rollers 22 is equipped with a self-locking first drive motor. The contact between the rollers 22 and the guide rail 11 enables the platform's mobility, while the self-locking function prevents positional shifting during operation. Furthermore, the presence of multiple rollers 22 provides balanced support for the base 2, enhancing overall operational stability.

[0037] Furthermore, to enhance the stability of roller 22 during movement and prevent slipping, guide rail 11 is provided with tooth grooves 111 along its length, and roller 22 is provided with annular teeth 221 along its circumference, which mesh with tooth grooves 111. This meshing structure, through mechanical engagement, ensures that the platform does not slip due to gravity when operating uphill or on a slope. A slider 23 is fixedly welded or bolted to the bottom wall of base 2. Slider 23 slides and engages with guide rail 11, further enhancing operational smoothness and track alignment accuracy, and preventing track deviation due to vibration.

[0038] In this embodiment, the first drive motor, the second drive motor and the third drive motor are all waterproof motors. At the same time, a waterproof cover can be installed on the turntable 3 or the base 2 and other structures to prevent rainwater from seeping in and affecting the working conditions of key components such as the gear 42 and the drive mechanism, thereby ensuring the stability and reliability of the long-term operation of the equipment and adapting to complex climate environments such as rainy outdoor environments.

[0039] In other embodiments, the first driving member 21, the second driving member 31 and the third driving member 41 may also use other driving structures such as rotating cylinders, so as to achieve diversified system configuration, select according to different energy supply conditions or environmental requirements, and improve system adaptability and module replacement flexibility.

[0040] Reference Figure 2 and Figure 3 As shown, to achieve synchronous rotation of the pair of swing arms 4, a gear 42 is integrally welded to one end of each swing arm 4 near the turntable 3. The two gears 42 mesh with each other. The turntable 3 is fixedly provided with an articulated seat 32, and the gear 42 is hingedly mounted on the articulated seat 32. This gear 42 transmission structure ensures that the pair of swing arms 4 maintain angular consistency during the driving process, preventing radar angle deviation caused by asynchronous movement and ensuring the stability and uniformity of the radar system's measurement direction.

[0041] Reference Figure 3 and Figure 4 As shown, a rotating ring 43 is integrally welded to the end of the swing arm 4 away from the turntable 3. A fixed seat 51 is fixedly welded to the top of the radar body 5. A rotating rod 511 is fixedly welded to the fixed seat 51. The rotating rod 511 is rotatably inserted into the rotating ring 43. An arc-shaped electromagnet 431 is embedded in the rotating ring 43. The rotating rod 511 is circumferentially embedded with multiple metal plates 512 that can attract the electromagnet 431. The distal end of the rotating rod 511 is fixedly connected to an end cap 5111 via bolts to prevent the rotating rod 511 from falling out of the rotating ring 43. This design allows the radar body 5 to automatically lock through electromagnetic attraction after positioning, preventing rotation or loosening during operation, thereby improving the device's pointing stability and measurement accuracy.

[0042] The following describes how the electromagnet 431 controls its working state: during the process of rotating the swing arm 4, the electromagnet 431 is in a power-off and non-attracted state, allowing the radar body 5 to rotate freely around the rotating rod 511; after the radar body 5 is in place, the swing arm action is stopped, and the radar will automatically droop vertically to a stable state under the action of gravity. At this time, the electromagnet 431 is controlled to be energized to attract the metal plate 512, thereby fixing the radar body 5 in the current vertical position, ensuring that the radar posture is consistent during each measurement, which is conducive to the consistency and comparability of the measurement data.

[0043] It should be noted that the telescopic arrangement of the swing arm 4 can be in the form of multiple telescopic tubes, internally equipped with a self-locking telescopic cylinder or electric cylinder to ensure that the current length and position are stable after extension and retraction. Alternatively, the swing arm 4 can be directly composed of a telescopic cylinder or electric cylinder body. This structural design can flexibly adjust the relative distance between the radar and the target area at different target distances, improving observation clarity and radar beam coverage efficiency.

[0044] To enhance the stability of the swing arm 4 during its swing, a fan-shaped support frame 33 is welded to the turntable 3. An arcuate slot 331 is defined in the support frame 33, and a sliding post 44 is welded to the swing arm 4. During the swing process, the sliding post 44 always slides within the arcuate slot 331, effectively limiting the swing trajectory of the swing arm 4, improving its stability and accuracy, preventing shaking and deviation during the swing process, and further ensuring the stability of the radar body 5 and the consistency of its measurement direction.

[0045] As a preferred embodiment, a pair of support brackets 33 are provided, one clamping each side of the pair of swing arms 4. This further enhances the lateral support and overall stability of the swing arms 4 during movement. This dual-sided support effectively offsets external wind forces or disturbances during operation, preventing adverse factors such as swing arm yaw and vibration, effectively ensuring stable operation and accurate measurement of the radar equipment in various environments.

[0046] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
