Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary scanning and mapping instruments, and specifically to a three-dimensional scanning and mapping device for water conservancy projects. Background Art

[0002] The process of three-dimensional scanning and mapping for water conservancy projects mainly includes equipment selection and on-site reconnaissance. Specifically, a three-dimensional laser scanner is erected at the measuring station position to ensure that the scanner can cover the area to be mapped. Then, the scanner is started, and the target is scanned at the set resolution and scanning speed to obtain point cloud data. During the scanning process, attention should be paid to avoiding occlusion and reflection interference to ensure the integrity of the data.

[0003] When conducting three-dimensional scanning and mapping for water conservancy projects, a good location needs to be selected to cover and map the area. However, when the ground is uneven, it will cause the scanner to tilt or be unstable during erection, thereby affecting the accuracy of the scanned data. This requires the staff to reselect the position or perform more calibration and adjustment work during post-data processing to eliminate the errors caused by the uneven ground. In this process, more preparatory work and adjustments are needed, increasing the operation difficulty. Therefore, a three-dimensional scanning and mapping device for water conservancy projects is proposed to address the above problems. Summary of the Invention

[0029] Please refer to Figure 1-8As shown in the figure, a three-dimensional scanning and mapping device for water conservancy projects includes a base 1; a plurality of circular through grooves are provided on the side wall of the base 1; a pair of limiting grooves 2 are provided in the circular through grooves; a limiting block 3 is slidably connected to the groove wall of the limiting groove 2; a support rod 4 is fixedly connected between the pair of limiting blocks 3; a threaded groove 5 is provided on the side wall of the support rod 4; a threaded block 6 is threadedly connected to the groove wall of the threaded groove 5; a connecting rod 7 is fixedly connected to the side wall of the threaded block 6; one end of the connecting rod 7 is fixedly connected to a rotating handle 8; the rotating handle 8 is rotatably connected to the base 1; a three-dimensional scanning and mapping instrument 9 is provided on the side wall of the base 1 through a rotating member; during operation, the staff rotates the rotating handle 8, so that the rotating handle 8 drives the threaded block 6 to rotate. Since the threaded block 6 is threadedly connected to the threaded groove 5 inside the support rod 4, the rotation of the threaded block 6 will drive the support rod 4 to slide in the circular through groove, so that the support rod 4 can rise and fall on the base 1, thereby adjusting the height of the mapping instrument to make it more adaptable to various terrains and ground conditions, so as to achieve a more stable support effect. This adjustment can ensure that the mapping instrument remains horizontal on uneven ground and reduce errors caused by uneven ground.

[0030] It also includes a multispectral soil sensor, a vibration ramming module, an inclination sensor and a controller. The multispectral soil sensor and the inclination sensor are arranged on the bottom surface of the base for detecting the ground compactness; the vibration ramming module is embedded in the support rod. The vibration ramming module includes a linear motor and a rammer head; the controller is electrically connected to the multispectral soil sensor, the vibration ramming module and the inclination sensor. The controller is configured to: when the detected ground compactness is lower than the threshold, start the vibration ramming module to perform periodic ground ramming, and compare the inclination changes measured by the inclination sensor before and after ramming after a set time period interval. If the inclination deteriorates by more than 15% in two consecutive periods, stop the machine and send a remote alarm.

[0031] The rammer head acts on the support rod under the drive of the linear motor, and the acting force is indirectly transmitted to the ground by the support rod. Specifically, the linear motor drives the rammer head to perform high-frequency reciprocating motion inside the support rod to generate vibration. The vibration energy of the rammer head is transmitted to the ground through the bottom of the support rod. The soil particles are rearranged under the action of vibration, and the compactness gradually increases. In this embodiment, by transmitting the vibration energy through the support rod, the vibration can be more evenly distributed to the ground, avoiding local over-ramming or under-ramming.

[0032] The device integrates the function of vibration ramming, can automatically perform ground ramming according to the detection result of soil compactness, and improve the compactness and stability of the foundation. Real-time monitoring of the inclination change of the device ensures the stability of the device during operation, and at the same time provides feedback for the ramming effect. Detecting parameters such as the compactness and water content of the soil through multispectral technology helps to evaluate the stability and bearing capacity of the foundation.
