Abstract
Description
Technical Field
[0001] This utility model relates to the field of surveying and mapping technology. More specifically, this utility model relates to a geological engineering exploration and surveying equipment. Background Technology
[0002] Geological exploration and mapping are systematic technical methods in the field of geological engineering. Their objects cover various elements related to geological structure, surface morphology, and underground facilities. By acquiring geological information, they provide a basis for geological environment analysis for engineering construction. According to different spaces, they can be mainly divided into surface observation and underground exploration.
[0003] In practical applications, due to differences in the types of equipment and measurement methods used, surface observation and underground exploration are usually conducted separately and independently. For example, total stations and 3D scanners are used to measure regional surface morphology data at designated measurement points, while ground-penetrating radar and metal detectors are used to scan and detect the distribution of underground media (such as geological structures, metals, and buildings). When a global assessment of geological data is required, the aforementioned surface morphology and underground media data are directly integrated to form a full-section topographic distribution map or 3D model. The integrated surface observation data and underground exploration data can be correlated and linked through planar coordinates. However, the positioning deviation of the equipment itself during the measurement process can easily cause correspondence errors between geological data and coordinate information. Under the condition of using different equipment for separate measurements, the relatively independent measurement and exploration process results in a larger correspondence deviation between surface observation data and underground exploration data, affecting the accuracy and reliability of important reference data for engineering construction planning.
[0004] To address the aforementioned issues, it is necessary to design a geological engineering surveying and mapping device to improve the comprehensiveness and accuracy of the acquired geological data. Summary of the Invention

[0027] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.
[0028] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are all conventional methods, and the reagents and materials described are all commercially available unless otherwise specified.

Therefore, they should not be construed as limitations on this utility model.
[0029] like Figure 1-2 As shown, this utility model provides a geological engineering surveying and mapping equipment, comprising:
[0030] The carriage is a box-shaped structure without a lid;
[0031] The support frame includes a bottom frame 21, which is a horizontally arranged rectangular frame structure; multiple vertical beams 22, which are spaced apart circumferentially on the bottom frame, and any vertical beam is fixedly connected to the bottom of the vehicle body; a protective plate 23, which is continuously arranged circumferentially between the bottom frame and the vehicle body and forms a semi-enclosed space with an opening at the bottom; a transverse partition 24, which is fixed in the middle along the width direction of the bottom frame and divides the semi-enclosed space into two parts; and a support plate, which is laid on the bottom frame located on one side of the transverse partition and forms a support platform.
[0032] Two sets of moving mechanisms are arranged opposite each other on both sides of the support frame and drive it to move along the ground. Each set of moving mechanisms includes multiple moving mechanisms, which are spaced apart along the length of the support frame.
[0033] The detection system includes a ground-penetrating radar 41 located on the other side of the transverse partition and mounted at the bottom of the vehicle body; a 3D scanner 42 located on the same side as the support plate and mounted inside the vehicle body via an adjusting bracket configured to adjust the height and detection direction of the 3D scanner; and a GNSS receiver 43 located on the side of the 3D scanner away from the ground-penetrating radar and mounted inside the vehicle body. The ground-penetrating radar, the 3D scanner, and the GNSS receiver are located in the same vertical plane along the length of the support frame.
[0034] A controller is installed inside the vehicle body and electrically connected to the moving mechanism and various components of the detection system.
[0035] The power battery 6 is mounted on the support plate and is used to power the moving mechanism, the detection system and the controller.
[0036] In the above technical solution, the vehicle body and the transverse partition work together to isolate three installation spaces: inside the vehicle body (above), on the left side of the support frame, and on the right side of the support frame. The ground-penetrating radar is installed in the space on the left side of the support frame, which is not obstructed from below. The space on the right side of the support frame is supported by a support plate, which can be used to install the power equipment (power battery) to support the operation of the overall surveying and mapping equipment. The 3D scanner and GNSS receiver are both installed in the space in the vehicle body directly above the support plate, staggered from the ground-penetrating radar both horizontally and vertically to avoid electromagnetic interference during operation, which would affect the measurement accuracy of the various components of the detection system. Setting the ground-penetrating radar, the 3D scanner, and the GNSS receiver to be located in the same vertical plane means that the detection center points of the above-mentioned components are located in the same vertical plane along the length of the support frame, which facilitates the rapid and accurate determination of the detection position / range of the ground-penetrating radar and the 3D scanner based on the positioning signal of the GNSS receiver during use.
[0037] During operation, the geological engineering surveying and mapping equipment is first moved to the designated detection point via a mobile mechanism. Then, a 3D scanner is used to collect surface morphology data within the target area as required. Combined with the real-time coordinate information acquired by the GNSS receiver and the working status (height, detection angle) of the adjustment support, the real-time coordinates and detection range information of the 3D scanner can be calculated, thus obtaining a precise correspondence between surface morphology data and 3D coordinate data. The controller automatically plans the detection path and points of the ground-penetrating radar based on the above correspondence. The path must cover the entire detection range previously covered by the 3D scanner. The geological engineering surveying and mapping equipment is then moved along the planned detection path via the mobile mechanism, and the ground-penetrating radar collects subsurface medium data at the corresponding points. The real-time coordinates of the ground-penetrating radar can be converted based on the real-time coordinate information acquired by the GNSS receiver and compared with the design coordinates of the detection points. When there is a large error, the working status of the mobile mechanism can be controlled to correct the real-time coordinates of the ground-penetrating radar. After collecting subsurface medium data at all detection points, the topographic data of the entire cross-section within the target area can be obtained. The above method can be used cyclically to measure multiple defined detection ranges.
[0038] Specifically, the vertical beams are welded and fixed to the bottom frame and the vehicle body; the protective plate is welded to the outside of the bottom frame and fixed to the bottom of the vehicle body; the transverse partition is welded between the bottom frame and the bottom of the vehicle body; and the support plate is mounted on the bottom frame and welded and fixed to it. All components of the vehicle body and support frame can be made of conventional steel. The ground-penetrating radar can be a conventional ground-penetrating radar, the 3D scanner can be a conventional 3D laser measuring instrument, and the GNSS receiver is a commercially available model. The controller is integrated inside a sealed control box, and the GNSS receiver can be installed on the top of the control box. The control box 51 also has a control panel 52, which displays the control information integrated and processed by the controller and can also send control commands to the controller via the control panel. The moving mechanism is electrically driven, and the power battery casing has a high-voltage output terminal and a low-voltage output terminal. The high-voltage output terminal directly powers the moving mechanism, and the low-voltage output terminal, after being stepped down (12V, 24V) by a DC-DC converter, powers the various components of the detection device.
[0039] This invention uses the same GNSS receiver to compare the three-dimensional coordinate information of the data collected by the ground-penetrating radar and the 3D scanner. Furthermore, the surface observation and underground exploration steps are carried out continuously within the same detection range, avoiding the influence of positioning errors of different devices on the correspondence between geological data and coordinate information. This significantly reduces the deviation between coordinate information of different geological (surface and underground) data. The semi-automated measurement method saves the amount of manual work required for exploration and mapping, improving measurement efficiency while ensuring the accuracy and reliability of the correspondence between the measured surface and underground data.
[0040] In another technical solution, the geological engineering surveying and mapping equipment includes a chassis comprising a floor plate 11, the top surface of which is a sloped surface with a fixed angle, inclined downwards from one side of the transverse partition near the support plate to the other side; multiple sets of columns 12, spaced apart along the length of the floor plate, each set comprising two columns fixed to the top two sides of the floor plate, with the tops of each column located on the same horizontal plane; and multiple side plates 13, fixedly connected to the multiple columns along the circumference of the floor plate, forming a three-sided enclosure structure that encloses the top two sides of the floor plate and the side where the higher end is located. This provides protection for the detection devices inside the chassis while preventing long-term accumulation of rainwater or other debris on the chassis floor plate, which could affect the normal operation of the electronic devices.
[0041] In another technical solution, the geological engineering survey and mapping equipment further includes three photovoltaic power generation devices. Each photovoltaic power generation device includes a back plate, a rotating shaft 73 is provided on one side along the length direction, and its two ends are respectively fixedly connected to the ends of the back plate through ear plates; a solar power generation panel is fixedly laid on the back plate; and a drive mechanism is configured to drive the rotating shaft to rotate.
[0042] The three photovoltaic power generation devices include two first photovoltaic power generation devices 71, which are mounted opposite each other on the columns on both sides of the base plate. The rotating shaft of any first photovoltaic power generation device is mounted on the top of multiple columns on the same side along the length direction of the vehicle body and is hinged to them. The width of the first photovoltaic power generation device is equal to 1 / 2 of the distance between two columns in the same group. The second photovoltaic power generation device 72 is mounted between a group of columns located at the lower end of the base plate. The rotating shaft of the second photovoltaic power generation device is hinged to the corresponding two columns along the width direction of the vehicle body and the top of the rotating shaft is flush with the top of each column. The width of the second photovoltaic power generation device is less than the height of its corresponding column. The solar panels of each photovoltaic power generation device are all set to be adjacent to the inner side wall of the vehicle body.
[0043] In the above technical solution, the irradiation angle of the solar panels can be adjusted by driving the rotating shaft through the drive mechanism. Under sunny conditions, all photovoltaic power generation devices unfold outwards (towards the vehicle body), with one side of the solar panel facing upwards. When the weather is bad and surveying work cannot be carried out, each photovoltaic power generation device can be folded inwards. The second photovoltaic power generation device folds inwards to a vertically downward position first, with one side of its solar panel inside the vehicle body and the back panel facing outwards. The first photovoltaic power generation device folds inwards to a horizontal position, with the back panel facing upwards. Thus, the vehicle body and each photovoltaic power generation device cooperate to form a relatively enclosed box space, protecting each detection device inside, allowing the geological engineering surveying and mapping equipment to better adapt to different regional environments and weather changes. The solar panels can be of conventional models, and each solar panel is electrically connected to the controller and charges the power battery through a DC-DC converter. The drive mechanism uses a small DC motor, which is electrically connected to the controller and powered by the low-voltage output terminal (24VDC) of the power battery. The drive mechanism of the first photovoltaic power generation device can be installed on the top of the column, and the drive mechanism of the second photovoltaic power generation device can be installed inside the corresponding column. Trusses 14 can be installed on the inner and outer sides of each column to support the larger first photovoltaic power generation device and keep it horizontal.
[0044] In another technical solution, the geological engineering surveying and mapping equipment includes electromagnetic shielding layers 8 within the base plate and the transverse diaphragm, respectively, to isolate the ground-penetrating radar from other components of the detection system and improve anti-interference performance. Specifically, the base plate has a horizontal mounting groove covering the entire (projected) plane of the support frame. The electromagnetic shielding layer within the base plate can be made of aluminum plate or permalloy plate, with the aluminum plate positioned above the permalloy plate. Both plates are fixed within the mounting groove and fill the gap between the aluminum plate and the base plate. Mounting grooves are also provided on both sides of the transverse diaphragm, covering as much of the diaphragm's surface as possible. The electromagnetic shielding layer within the transverse diaphragm can be made of aluminum plate or permalloy plate, with the aluminum plate fixedly embedded in the mounting groove on the side closest to the support plate and the permalloy plate fixedly embedded in the mounting groove on the side closest to the ground-penetrating radar.
[0045] In another technical solution, the geological engineering surveying and mapping equipment includes a triangular track wheel 31 for each moving mechanism, which is fixedly connected to the bottom frame via a triangular bracket; and a drive motor 32, which is fixedly mounted on the bottom frame and whose output shaft is connected to the drive wheel of the triangular track wheel. This allows the geological engineering surveying and mapping equipment to better adapt to various terrain conditions and maintain stable movement.
[0046] The triangular track wheel is a conventional model, mainly comprising a track, a triangular bracket, a drive wheel, and driven wheels. The drive wheel is located at the top of the triangular bracket, and multiple driven wheels (including support wheels and tensioning wheels) are located at the bottom of the triangular bracket. The track is fitted around the drive wheel and each driven wheel from the outside along the circumference of the triangular bracket and is connected to them for transmission. In this embodiment, the bottom frame is welded to the inner wall of the triangular bracket, allowing the output shaft of the drive motor installed at the corresponding position on the bottom frame to be easily aligned with the rotation shaft of the drive wheel and connected to it for transmission (i.e., driving the drive wheel to rotate). The drive motor can be a DC motor, controlled by the same controller, and powered by a power battery. The protective plate has a notch at the position of the triangular track wheel that adapts to the shape of the triangular bracket, allowing the triangular bracket to be easily fixedly connected to the bottom frame at that position, and also facilitating the installation and docking of the drive motor.
[0047] In another technical solution, the geological engineering surveying and mapping equipment includes a ground-penetrating radar installed at the bottom of the vehicle body via a lifting bracket. The lifting bracket includes a lifting frame, which is a horizontally arranged grid-shaped planar frame. The top of the ground-penetrating radar is fixed to the bottom of the lifting frame. A lifting mechanism has its fixed end fixedly connected to the bottom of the vehicle body and its lifting end vertically downward and fixedly connected to the center of the top surface of the lifting frame. Multiple connecting rods are spaced apart along the circumference of the lifting frame. Each connecting rod is vertically arranged and includes two sleeves. One sleeve is fitted onto the outside of the other sleeve and slidably connected to it along the axial direction. The outer ends of the two sleeves are fixedly connected to the bottom of the vehicle body and the top of the lifting frame, respectively. A compression spring is fitted on the outside of the connecting rod, and its two ends abut against the bottom of the vehicle body and the top of the lifting frame, respectively.
[0048] In the above technical solution, the measuring height of the ground-penetrating radar can be adjusted in real time via a lifting support. When abnormal data collection occurs during the detection process, the distance between the ground-penetrating radar and the ground can be adjusted appropriately to ensure the clarity and accuracy of the underground mapping data. The lifting mechanism is electrically connected to the controller and powered by a power battery. The lifting mechanism can use conventional lifting equipment such as jacks and hydraulic cylinders, and its supporting hydraulic pump station can be installed in the overhead vehicle compartment.
[0049] In another technical solution, the geological engineering surveying and mapping equipment includes an adjustment support comprising an adjustment platform 91 with an adjustment groove 92 on its top surface and a circular cross-section; multiple linear guide rails 93 spaced around the adjustment platform, each linear guide rail being fixed vertically to the bottom plate of the carriage, the adjustment platform being fixedly connected to the sliders of each linear guide rail; an adjustment plate horizontally fitted into the adjustment groove and slidably connected thereto, the 3D scanner being fixedly mounted on the adjustment plate; a pushing device 94 fixed to the bottom of the adjustment platform with its pushing end vertically upward through the adjustment groove; and a rotating mechanism 95 fixed to the pushing end of the pushing device with its rotating shaft fixedly connected vertically to the bottom center of the adjustment plate.
[0050] The adjustment platform is located between the linear guides and moves vertically under their drive. The top of the linear guide is lower than the top of the column, the height of the adjustment platform is lower than the length (height) of the linear guide, and the depth (height) of the adjustment groove is greater than the height of the 3D scanner. Therefore, when the 3D scanner is not in use, it can be stored inside the adjustment platform through dual height adjustment via the linear guides and the pushing mechanism. Simultaneously, the adjustment platform is lowered below the top of the vehicle body (i.e., the top of the column). This provides protection for the 3D scanner through the adjustment platform's own structure and also provides overall protection for the detection system through the side panel structure of the vehicle body, minimizing damage to the 3D scanner from harsh environments. The linear guides, pushing device, and rotation mechanism are all electrically connected to the controller and powered by a power battery. The pushing device can be an electric push rod, and the rotation mechanism can be a rotary motor.
[0051] The adjustment bracket also includes a cover plate. When the 3D scanner is completely retracted into the adjustment platform, the cover plate can be placed on top of the adjustment platform to prevent water from seeping into the adjustment tank in rainy weather.
[0052] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
