Description

Technical Field

[0001] This invention relates to the field of auxiliary scanning and mapping equipment technology, specifically a three-dimensional scanning and mapping device for water conservancy projects. Background Technology

[0002] The process of 3D scanning and mapping for water conservancy projects mainly includes equipment selection and on-site reconnaissance. Specifically, a 3D laser scanner is set up at the survey station location to ensure that the scanner can cover the area to be surveyed. The scanner is then started and scanned at the set resolution and scanning speed to obtain point cloud data. During the scanning process, care should be taken to avoid occlusion and reflection interference to ensure the integrity of the data.

[0003] When conducting 3D scanning and mapping for water conservancy projects, it is necessary to select a suitable location for comprehensive mapping of the area. However, uneven ground can cause the scanner to tilt or become unstable during setup, affecting the accuracy of the scanned data. This necessitates staff to reselect the location or perform more corrections and adjustments during subsequent data processing to eliminate errors caused by uneven ground. This process requires more preparation and adjustments, increasing the operational difficulty. Therefore, this paper proposes a 3D scanning and mapping device for water conservancy projects to address the above problems. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, when conducting 3D scanning and mapping of water conservancy projects, it is necessary to select a good location for coverage mapping of the area. However, when the ground is uneven, the scanner may tilt or become unstable during setup, thus affecting the accuracy of the scanned data. This requires staff to reselect the location or to perform more correction and adjustment work during later data processing to eliminate the errors caused by the uneven ground. This process requires more preparation and adjustment, increasing the difficulty of operation. This invention proposes a 3D scanning and mapping device for water conservancy projects.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: A three-dimensional scanning and mapping device for water conservancy projects, comprising a base; multiple sets of circular through grooves are provided on the side wall of the base; a pair of limiting grooves are provided within each circular through groove; limiting blocks are slidably connected to the groove walls of the limiting grooves; a support rod is fixedly connected between the pair of limiting blocks; a threaded groove is provided on the side wall of the support rod; a threaded block is threadedly connected to the groove wall of the threaded groove; a connecting rod is fixedly connected to the side wall of the threaded block; a rotating handle is fixedly connected to one end of the connecting rod; the rotating handle is rotatably connected to the base; a three-dimensional scanning and mapping instrument is mounted on the side wall of the base via a rotating component.

[0006] It also includes a multispectral soil sensor, a vibration compaction module, a tilt sensor, and a controller. The multispectral soil sensor and the tilt sensor are located on the bottom surface of the base and are used to detect ground compaction. The vibration compaction module is embedded in the support rod and includes a linear motor and an impact head. The controller is electrically connected to the multispectral soil sensor, the vibration compaction module, and the tilt sensor. The controller is configured to: start the vibration compaction module to perform periodic ground compaction when the ground compaction is detected to be below a threshold; compare the change in tilt measured by the tilt sensor before and after compaction at set time intervals; if the tilt deteriorates by more than 15% for two consecutive cycles, stop the machine and send a remote alarm.

[0007] This adjustment makes it more adaptable to various terrains and ground conditions, thus achieving a more stable support effect. This adjustment ensures that the surveying instrument can remain level even on uneven ground, reducing errors caused by uneven ground.

[0008] Preferably, the side wall of the support rod is provided with a pair of placement grooves; both sides of the placement groove are provided with sliding grooves; the side wall of the sliding groove is slidably connected to a slider; the side wall of the slider is provided with an auxiliary rod through a locking component, and the operator can open the auxiliary rod from the placement groove to support the bottom of the auxiliary rod with the ground, further improving the stability of the surveying instrument, distributing the weight of the surveying instrument, and reducing tilting or shaking caused by uneven ground.

[0009] Preferably, the locking component includes a circular block; both side walls of the auxiliary rod are provided with circular grooves; a circular block is slidably connected to the side wall of the circular groove; the circular block is rotatably connected to the slider; a spring is fixedly connected between the circular block and the circular groove; the side wall of the slide groove is provided with multiple sets of locking grooves; the locking grooves match the slider; the side wall of the auxiliary rod is provided with a through groove; the through groove communicates with the circular groove; a stop plate is slidably connected to the side wall of the through groove; the side wall of the stop plate is fixedly connected to the slider; the stop plate matches the circular block, enabling the auxiliary rod to rotate and slide within the placement groove, enhancing the flexibility of the auxiliary rod and improving the ease of operation for the operator.

[0010] Preferably, the rotating component includes a disc; the upper surface of the base is rotatably connected to the disc; an extension block is fixedly connected to the side wall of the disc; a pin is slidably connected to the side wall of the extension block; the upper surface of the base is provided with multiple sets of slots; the slots match the pins; a bracket is provided on the top of the disc; the 3D scanning and mapping instrument is mounted on the top of the bracket, which can help the 3D scanning and mapping instrument find the optimal scanning position and angle, improve measurement efficiency and enhance flexibility.

[0011] Preferably, the top of the disc is provided with multiple sets of sliding grooves; L-shaped blocks are slidably connected to the side walls of the sliding grooves; springs are fixed between the L-shaped blocks and the sliding grooves; a limiting plate is placed between the multiple sets of L-shaped blocks; the bracket is fixed to the limiting plate; the side walls of the disc are provided with limiting components, which facilitates the installation and removal of the 3D scanning and mapping instrument on the base by the staff, making it easy for the staff to carry and transport the instrument and quickly deploy it to the base, thus improving work efficiency.

[0012] Preferably, the limiting component includes a rotating ring; the rotating ring is rotatably connected to the side wall of the disc; multiple sets of arc-shaped blocks are fixed to the inner circular wall of the rotating ring; an extrusion block is fixed to the side wall of the L-shaped block; the extrusion block matches the arc-shaped block, which simplifies the operation difficulty of installation and disassembly for the staff and improves the ease of use of the equipment.

[0013] Preferably, both the side walls of the extrusion block and the arc-shaped block are designed as inclined surfaces, which reduces resistance and improves sliding efficiency when the operator rotates the rotating ring to drive the arc-shaped block to extrude the extrusion block.

[0014] Preferably, the sidewall of the slider is rounded, which helps the slider enter the locking groove more smoothly, reduces the possibility of jamming or stopping, and facilitates the slider to enter the locking groove for limiting.

[0015] The advantages of this invention are:

[0016] 1. By rotating the handle, the operator can rotate the threaded block. Since the threaded block is connected to the threaded groove inside the support rod, the rotation of the threaded block will cause the support rod to slide in the circular through groove, allowing the support rod to rise and fall on the base. This adjusts the height of the surveying instrument, making it more adaptable to various terrains and ground conditions, thus achieving a more stable support effect. This adjustment ensures that the surveying instrument remains level even on uneven ground, reducing errors caused by uneven ground.

[0017] 2. The auxiliary rod can be opened from the placement slot, allowing its bottom to be supported on the ground, further improving the stability of the surveying instrument. This distributes the weight of the surveying instrument, reducing tilting or swaying caused by uneven ground. The auxiliary rod can rotate and slide within the placement slot, enhancing its flexibility and improving the ease of operation for the staff. The 3D scanning surveying instrument can rotate on the base, helping it find the optimal scanning position and angle, improving measurement efficiency and enhancing flexibility.

[0018] 3. The equipment integrates a vibratory compaction function, which can automatically compact the ground based on the soil density test results, improving the density and stability of the foundation. Real-time monitoring of the equipment's tilt changes ensures stability during operation and provides feedback on the compaction effect. Multispectral technology is used to detect soil parameters such as density and moisture content, helping to assess the stability and bearing capacity of the foundation. Attached Figure Description

[0038] Please see Figure 1-8As shown, a three-dimensional scanning and mapping device for water conservancy projects includes a base 1; the side wall of the base 1 is provided with multiple sets of circular through grooves; a pair of limiting grooves 2 are provided in the circular through grooves; limiting blocks 3 are slidably connected to the groove walls of the limiting grooves 2; a support rod 4 is fixedly connected between the pair of limiting blocks 3; the side wall of the support rod 4 is provided with a threaded groove 5; 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; a rotating handle 8 is fixedly connected to one end of the connecting rod 7; the rotating handle 8 is rotatably connected to the base 1; the side wall of the base 1 is provided with multiple sets of circular through grooves; a pair of limiting grooves 2 are provided in the circular through grooves; limiting blocks 3 are slidably connected to the groove walls of the limiting grooves 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; a rotating handle 8 is fixedly connected to one end of the connecting rod 7; the rotating handle 8 is rotatably connected to the base 1; the side wall of the base 1 is provided with multiple sets of circular through grooves 2; limiting blocks 3 are slidably connected to the groove walls of the threaded grooves 2; a supporting 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 walls of the threaded groove 5; a connecting rod 7 is fixedly connected to the side wall of the threaded block 6; a rotating handle 8 is rotatably The rotating part is equipped with a three-dimensional scanning surveying instrument 9. During operation, the operator rotates the rotating handle 8, which in turn 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 cause the support rod 4 to slide in the circular through groove, allowing the support rod 4 to rise and fall on the base 1. This adjusts the height of the surveying instrument, making it more adaptable to various terrains and ground conditions, thereby achieving a more stable support effect. This adjustment can ensure that the surveying instrument remains level even on uneven ground, reducing errors caused by uneven ground.

[0039] It also includes a multispectral soil sensor, a vibration compaction module, a tilt sensor, and a controller. The multispectral soil sensor and the tilt sensor are located on the bottom surface of the base and are used to detect ground compaction. The vibration compaction module is embedded in the support rod and includes a linear motor and an impact head. The controller is electrically connected to the multispectral soil sensor, the vibration compaction module, and the tilt sensor. The controller is configured to: start the vibration compaction module to perform periodic ground compaction when the ground compaction is detected to be below a threshold; compare the change in tilt measured by the tilt sensor before and after compaction at set time intervals; if the tilt deteriorates by more than 15% for two consecutive cycles, stop the machine and send a remote alarm.

[0040] Driven by a linear motor, the impact head acts on a support rod, which indirectly transmits the force to the ground. Specifically, the linear motor drives the impact head to perform high-frequency reciprocating motion inside the support rod, generating vibration. The vibrational energy of the impact head is transmitted to the ground through the bottom of the support rod. Soil particles rearrange under the action of vibration, gradually increasing the compaction. In this embodiment, transmitting vibrational energy through the support rod allows for a more even distribution of vibration across the ground, avoiding localized over-compaction or under-compaction.

[0041] The equipment integrates vibration compaction, enabling automatic ground compaction based on soil density testing results, thereby improving the density and stability of the foundation. Real-time monitoring of equipment tilt changes ensures stability during operation and provides feedback on compaction effectiveness. Multispectral technology is used to detect soil parameters such as density and moisture content, helping to assess the foundation's stability and bearing capacity.

[0042] The support rod 4 has a pair of placement grooves 10 on its side wall; each side wall of the placement groove 10 has a sliding groove 11; a slider 12 is slidably connected to the side wall of the sliding groove 11; an auxiliary rod 13 is provided on the side wall of the slider 12 through a locking member; during operation, the slider 12 slides in the sliding groove 11, thereby driving the auxiliary rod 13 to slide in the placement groove 10. Under the action of the locking member, the auxiliary rod 13 and the slider 12 can rotate, and the rotation of the auxiliary rod 13 on the slider 12 can be limited. The operator can open the auxiliary rod 13 from the placement groove 10, so that the bottom end of the auxiliary rod 13 is supported with the ground, further improving the stability of the surveying instrument, distributing the weight of the surveying instrument, and reducing tilting or shaking caused by uneven ground.

[0043] The locking component includes a circular block 14; both sides of the auxiliary rod 13 are provided with circular grooves 15; the circular block 14 is slidably connected to the side wall of the circular groove 15; the circular block 14 is rotatably connected to the slider 12; a spring is fixedly connected between the circular block 14 and the circular groove 15; the side wall of the slide groove 11 is provided with multiple sets of locking grooves 16; the locking grooves 16 match the slider 12; the side wall of the auxiliary rod 13 is provided with a through groove 17; the through groove 17 communicates with the circular groove 15; a stop plate 18 is slidably connected to the side wall of the through groove 17; the stop plate 18 is slidably connected to the side wall of the through groove 17; the stop plate 18 is slidably connected to the side wall of the through groove 17; the stop plate 18 is slidably connected to the side wall of the through groove 17; the stop plate 18 is slidably connected to the side wall of the slide groove 13; the stop plate 14 ...8 is slidably connected to the side wall of the slide groove 13; the stop plate 18 is slidably connected to the side wall of the slide groove 13; the stop plate 18 is slidably connected to the side wall of The side wall of plate 18 is fixed to slider 12; the abutment plate 18 matches the circular block 14; during operation, the operator pulls the abutment plate 18 to slide in the through groove 17, so that the abutment plate 18 will abut against the circular block 14 to slide in the circular groove 15, and then the circular block 14 will drive the slider 12 to slide, so that one end of the slider 12 will disengage from the locking groove 16, so that the slider 12 can drive the auxiliary rod 13 to slide in the sliding groove 11, realizing that the auxiliary rod 13 can rotate and slide in the placement groove 10, enhancing the flexibility of the auxiliary rod 13 and improving the convenience of operation for the operator.

[0044] The rotating component includes a disc 19; the disc 19 is rotatably connected to the upper surface of the base 1; an extension block 20 is fixedly connected to the side wall of the disc 19; a pin 21 is slidably connected to the side wall of the extension block 20; multiple sets of slots 22 are provided on the upper surface of the base 1; the slots 22 match the pins 21; a bracket 23 is provided on the top of the disc 19; the 3D scanning and mapping instrument 9 is mounted on the top of the bracket 23; during operation, the disc 19 rotates on the base 1, thereby driving the bracket 23 to rotate, and then the bracket 23 to rotate, driving the 3D scanning and mapping instrument 9 to rotate. The pin 21 on the extension block 20 can be inserted into the slot 22 to limit the rotation of the disc 19, and the 3D scanning and mapping instrument 9 can rotate on the base 1, which helps the 3D scanning and mapping instrument 9 find the best scanning position and angle, improves measurement efficiency and enhances flexibility.

[0045] The top of the disc 19 is provided with multiple sets of sliding grooves 24; L-shaped blocks 25 are slidably connected to the side walls of the sliding grooves 24; springs are fixed between the L-shaped blocks 25 and the sliding grooves 24; a limiting plate 26 is placed between the multiple sets of L-shaped blocks 25; the bracket 23 is fixedly connected to the limiting plate 26; the side walls of the disc 19 are provided with limiting components; during operation, the L-shaped blocks 25 slide within the sliding grooves 24, and under the action of the limiting components, the L-shaped blocks 25 can slide towards the center of the disc 19, thereby limiting the limiting plate 26. This facilitates the installation and removal of the 3D scanning and mapping instrument 9 on the base 1 by the staff, making it easier for the staff to carry and transport the instrument and quickly deploy it onto the base 1, thus improving work efficiency.

[0046] The limiting component includes a rotating ring 27; the rotating ring 27 is rotatably connected to the side wall of the disc 19; multiple sets of arc-shaped blocks 28 are fixed to the inner circular wall of the rotating ring 27; a pressing block 29 is fixed to the side wall of the L-shaped block 25; the pressing block 29 matches the arc-shaped block 28; during operation, by rotating the rotating ring 27, the arc-shaped block 28 on the rotating ring 27 will contact the pressing block 29 on the L-shaped block 25. After the arc-shaped block 28 presses the pressing block 29, the pressing block 29 will be pressured and drive the L-shaped block 25 to slide in the sliding groove 24, so that the L-shaped block 25 will limit and fix the limiting disc 26, which simplifies the operation difficulty of the operator's installation and disassembly and improves the ease of use of the equipment.

[0047] Both sides of the extrusion block 29 and the arc block 28 are set as inclined surfaces. During operation, the inclined surfaces of the side walls of the extrusion block 29 and the arc block 28 allow the operator to rotate the rotating ring 27 to drive the arc block 28 to extrude the extrusion block 29, thereby reducing resistance and improving sliding efficiency.

[0048] The sidewall of the slider 12 is rounded. During operation, the rounded sidewall of the slider 12 helps the slider 12 to enter the locking groove 16 more smoothly, reducing the possibility of jamming or stopping, and making it easier for the slider 12 to enter the locking groove 16 for limiting.

[0049] The working principle is as follows: The operator rotates the handle 8, which in turn rotates the threaded block 6. 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 causes the support rod 4 to slide within the circular through groove. This allows the support rod 4 to rise and fall on the base 1, thereby adjusting the height of the surveying instrument to better adapt to various terrains and ground conditions, achieving a more stable support effect. This adjustment ensures that the surveying instrument remains level even on uneven ground, reducing errors caused by uneven ground. The slider 12 slides within the slide groove 11, causing the auxiliary rod 13 to slide within the placement groove 10. Under the action of the locking component, the auxiliary rod 13 can rotate between itself and the slider 12, and... The auxiliary rod 13 is limited in its rotation on the slider 12. The operator can open the auxiliary rod 13 from the placement slot 10, allowing its bottom end to support the ground, further improving the stability of the surveying instrument. This distributes the weight of the instrument and reduces tilting or swaying caused by uneven ground. The operator pulls the abutment plate 18, which slides through the through slot 17. This abutment plate 18 then pushes the circular block 14 against the circular groove 15, causing it to slide. The circular block 14 then drives the slider 12 to slide, disengaging one end of the slider 12 from the locking slot 16. This allows the slider 12 to drive the auxiliary rod 13 to slide within the sliding groove 11, enabling the auxiliary rod 13 to rotate and slide within the placement slot 10. This enhances the flexibility of the auxiliary rod 13 and improves the operator's control. For ease of use, the disc 19 rotates on the base 1, which in turn rotates the bracket 23, which in turn rotates the 3D scanning and mapping instrument 9. The pin 21 on the extension block 20 can be inserted into the slot 22 to limit the rotation of the disc 19. The 3D scanning and mapping instrument 9 can rotate on the base 1, helping it find the optimal scanning position and angle, improving measurement efficiency and enhancing flexibility. The L-shaped block 25 slides within the sliding groove 24, and under the action of the limiting component, it can slide towards the center of the disc 19, thereby limiting the limiting plate 26. This facilitates the installation and removal of the 3D scanning and mapping instrument 9 on the base 1, making it easy for personnel to carry, transport, and quickly deploy. The 3D scanning and mapping instrument 9 is mounted on the base 1, improving work efficiency. When the operator rotates the rotating ring 27, the arc-shaped block 28 on the rotating ring 27 contacts the pressing block 29 on the L-shaped block 25. After the arc-shaped block 28 presses the pressing block 29, the pressure on the pressing block 29 causes the L-shaped block 25 to slide within the sliding groove 24, thus limiting and fixing the limiting plate 26. This simplifies the installation and disassembly process and improves the ease of use of the equipment. The inclined sidewalls of the pressing block 29 and the arc-shaped block 28 reduce resistance and improve sliding efficiency when the operator rotates the rotating ring 27 to press the arc-shaped block 28 against the pressing block 29. The rounded sidewalls of the slider 12 help it enter the locking groove 16 more smoothly.To reduce the possibility of jamming or stalling, it facilitates the movement of slider 12 into the locking slot 16 for positioning.
