Description

Technical Field

[0001] This invention relates to the field of surveying equipment technology, specifically a portable engineering surveying device. Background Technology

[0002] In field operations in environmental engineering, geological exploration, precision agriculture, and disaster emergency assessment, two core tasks are typically involved: first, mapping and sensing the spatial and environmental information of the work area (such as topography, temperature, humidity, and gas composition); and second, collecting and analyzing surface or shallow subsurface samples (such as soil and sediments). Currently, these two types of work generally rely on independent equipment and workflows: surveyors use total stations, 3D laser scanners, or detectors equipped with multiple sensors to acquire spatial data; sampling personnel use manual or motorized samplers to acquire physical samples.

[0003] Chinese Patent Publication No. CN 220582165 U discloses a portable engineering surveying device, relating to the technical field of engineering surveying devices. This utility model includes a support plate and a mounting plate. The mounting plate is disposed on top of the support plate, and an adjustment component is provided at the bottom of the support plate. An installation component is provided on the top of the mounting plate, and a positioning component is provided on the installation component. The installation component includes a first fixing plate and a second fixing plate disposed on the top of the mounting plate. A first sliding groove is formed on one side of the first fixing plate, and a first slider is disposed within the first sliding groove. A first threaded through hole is formed on the other side of the first fixing plate, and a second threaded through hole is formed on one side of the first slider. This utility model is a portable engineering surveying device that allows for quick disassembly and easy carrying, greatly improving surveying efficiency.

[0004] However, the above solution still has the following problems:

[0005] The work is inefficient, requiring multiple visits to the same area, and involves complex coordination of personnel and equipment, which is time-consuming and labor-intensive.

[0006] Manually recording sampling points and on-site environmental parameters is prone to errors, making it difficult for subsequent laboratory analysis data to accurately correspond with the actual on-site situation, thus affecting the scientific validity and reliability of the conclusions.

[0007] Insufficient adaptability to the field; professional surveying and heavy sampling equipment is often bulky and relies on external power sources, making it difficult to deploy quickly and move flexibly in areas without roads or with complex terrain, thus failing to meet normal usage requirements.

[0008] Therefore, the present invention requires the design of a portable engineering surveying device to solve the above-mentioned problems. Summary of the Invention

A connecting plate is fixedly connected to one side of each of the two limiting sliders, and one end of each of the two connecting plates is fixedly connected to the field acquisition equipment.

[0019] In a preferred embodiment of the present invention, a first drive motor is fixedly connected inside the electrical control compartment.

Workers can push or tow it for short distances using a height-adjustable handle. Adjusting the slide bar and second positioning bolt allows the device to function as a stable mobile workstation once it reaches the designated work area. The control panel activates the first drive motor, which rotates the reciprocating lead screw, causing the threaded limit slider and connecting plate to move vertically along the limit guide rail inside the fixed column, thus raising and lowering the on-site sampling equipment to the optimal observation height. The third drive motor then activates, driving the spiral conveyor rod to rotate at high speed, cutting and conveying soil upwards from the sampling port. The lifted soil is conveyed through a pipeline to the diversion pipe. The device employs a modular design to ensure portability: the portable support column and support base plate are connected by threads and are detachable; the sampling mechanism is fixed to the support base plate with bolts. This design facilitates disassembly and maintenance, allowing for partial disassembly during transport to save space and meet the practical needs of field equipment handling. Furthermore, the portability of this invention is relative to large, fixed equipment or separate equipment requiring truck transport; it refers to equipment that can be transported by small off-road vehicles and quickly deployed and moved by a single operator in the field. The support base plate has threaded grooves inside for mounting the portable support column. These grooves, along with the support base plate, allow for positioning and installation. Removing the second positioning bolt allows the adjusting slide rod to be pulled upwards from inside the portable support column to the desired height. The second positioning bolt then limits the height, accommodating users of different heights. The first positioning bolt connects the auxiliary positioning plate and the adjusting slide rod, facilitating partial disassembly and maintenance of the convenient mechanism. The detachable and retractable design saves space, thus improving overall portability. Attached Figure Description

[0055] In this design, casters 21 are installed around the bottom of the support base plate 2.

[0056] Please see Figures 1-7 The working principle of this invention is as follows:

[0057] It is equipped with a portable support column 1, a support base plate 2, and a field data acquisition device 3. When using it, open the control panel 18:

[0058] Move and position:

[0059] The device can move on relatively flat ground in the field by means of four casters 21 at the bottom. The staff can push or tow it for short distances by means of height adjustable portable handle 14. It can be adjusted by adjusting slide bar 11 and second positioning bolt 17. After arriving at the predetermined work area, the device itself is a stable mobile workstation.

[0060] Simultaneous collection of spatial and environmental information:

[0061] Height adjustment: The control panel 18 starts the first drive motor 37, which drives the reciprocating lead screw 34 to rotate, thereby causing the limit slider 35 and the connecting plate 32 that are threadedly engaged with it to move vertically along the limit guide rail 36 in the fixed column 31, thereby raising and lowering the field acquisition device 3 to the optimal observation height.

[0062] Multi-parameter sensing: The second drive motor 44 at the bottom of the field acquisition device 3 can drive the monitoring camera 4 to perform 360° rotation shooting. Multiple sensors 42 arranged around the camera can be configured as sensors for gas, temperature and humidity, particulate matter, illuminance, etc., and simultaneously collect multi-dimensional environmental information of the target point with the assistance of the supplementary light 43. All sensing data is transmitted to the control panel 18 in real time.

[0063] Automated sampling and sorting of soil at fixed points:

[0064] Sampling point alignment and downward movement: After determining the specific sampling point through the above sensing, the control panel 18 controls the electric telescopic rod 51 to extend downward, pushing the entire sampling mechanism, such as the sampling channel 6, to descend, so that the sampling port 66 is compacted or cuts into the ground.

[0065] Sample collection and transportation: The third drive motor 52 starts, driving the spiral conveyor rod 67 to rotate at high speed, cutting and transporting the soil upward from the sampling port 66;

[0066] Automatic sample sorting and storage: The lifted soil reaches the diversion pipe 69 through the delivery pipe 62 and is evenly distributed to three parallel filter chambers 63. The sampling storage chamber 64 at the bottom of each filter chamber is equipped with filter screens 68 with different pore sizes, so as to realize the automatic collection of soil samples according to particle size.

[0067] The control panel 18 is used to control the operation of the lighting lamp 19, solar photovoltaic panel 23, energy storage compartment 24, charging controller 25, field acquisition device 3, electrical control compartment 33, first drive motor 37, buzzer 38, backup battery 39, monitoring camera 4, installation sensor 42, first supplementary light 43, second drive motor 44, electric telescopic pole 51, fourth positioning bolt 52, and second supplementary light 65, realizing unified management of power equipment. Corresponding sensors measure corresponding environmental parameters, convert them into signals, and send them to the control panel 18. The control panel 18 receives and processes the signals, and generates corresponding control signals according to the preset control algorithm. As the brain, the control panel 18 not only sends control commands, but also receives and processes data from all sensors and motor statuses.

[0068] The solar photovoltaic panel 23 has an integrated circuit inside. When light shines on the solar photovoltaic panel 23, the photosensitive material in the panel, such as silicon, absorbs the light energy, excites electrons and generates current. These currents are collected by the integrated circuit and converted into direct current. The charging controller 25 is used to manage the electrical energy generated by the photovoltaic panel and regulate the voltage and current to ensure the safe charging of the battery. The battery is stored in the energy storage compartment 24 to provide continuous power for the whole device. The backup battery 39 ensures that critical operations are uninterrupted. The lighting lamp 19 provides lighting for nighttime operations.

[0069] The device adopts a modular design to ensure portability: the portable support column 1 and the support base plate 2 are connected by threads and can be disassembled; the sampling mechanism is fixed to the support base plate 2 by bolts, which facilitates disassembly and maintenance, so that the device can be partially disassembled during transportation to save space, which meets the actual needs of field equipment handling.

[0070] Meanwhile, the portability of this invention is relative to large fixed equipment or separate equipment that requires truck transportation; it refers to equipment that can be transported by small off-road vehicles and quickly deployed and moved by a single operator in the field.

[0071] The support base plate 2 has a threaded groove inside to accommodate the portable support column 1. The portable support column 1 and the support base plate 2 are positioned and installed through the threaded groove. The second positioning bolt 17 can be removed to easily pull the adjusting slide rod 11 upward from inside the portable support column 1 until the desired height is reached. The second positioning bolt 17 is used to limit the position again to accommodate the use of staff of different heights. The auxiliary positioning plate 12 and the adjusting slide rod 11 are positioned and connected by the first positioning bolt 16, which facilitates partial disassembly and maintenance of the convenient mechanism. The detachable and retractable design saves space and improves the overall portability.
