Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0026] Physical geography focuses on the natural environment on Earth, including aspects such as climate, hydrology, geomorphology, soil, vegetation, and zoogeography. It explores the formation, distribution, interaction, and change laws of these natural elements. Geographic information data collection refers to the process of obtaining geospatial data using various technologies and methods. These data can be used for the establishment and analysis of geographic information systems (GIS). Geographic information data collection is a complex process involving multiple technologies and methods, which requires following certain standards and procedures. At the same time, it is necessary to continuously introduce the latest technologies and tools to improve the efficiency and accuracy of data collection;

[0027] During the process of geographic information data collection, the collection equipment used is generally mounted on the corresponding workbench. Most of the existing workbenches for geographic information data collection are not convenient for applying to different geographical environments for geographic information data collection work, and are not convenient for effectively protecting the geographic information data collection equipment mounted on them and for convenient disassembly and assembly.

[0028] In view of the problems existing in the above-mentioned prior art, according to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown, this embodiment provides an adaptive horizontal workbench for geographic information data collection, including a hollow machine table 1 and a first motor 2 fixed to the right side of the top of the machine table 1. A turntable 3 is rotatably connected to the top of the machine table 1, and the turntable 3 is driven to rotate by the first motor 2. Two groups of support plates 4 distributed symmetrically left and right are fixed to the top of the turntable 3 by bolts. A signal transceiver 5 for receiving and transmitting geographic information data is clamped between the two groups of support plates 4. The signal transceiver 5 is placed on the top of the turntable 3. A horizontal adjustment table 7 is hinged to the top of the support plate 4, and the horizontal adjustment table 7 is driven by a cylinder 6 for tilting adjustment to adjust the levelness of the horizontal adjustment table 7. An electronic level 8 is fixed to the front of the horizontal adjustment table 7 by bolts. The electronic level 8 is connected to the PLC control system of the adaptive horizontal workbench, and is used to drive the cylinder 6 to work when detecting that the horizontal adjustment table 7 is uneven, detect the levelness of the horizontal adjustment table 7 through the electronic level 8, and drive the horizontal adjustment table 7 to tilt and adjust to the horizontal state through the cylinder 6, so that the horizontal adjustment table 7 can adaptively maintain the horizontal;

[0029] A data collection camera 9 for collecting geographic information data is placed on the top of the horizontal adjustment table 7, and the data collection camera 9 is clamped and fixed to the top of the horizontal adjustment table 7 through a second clamping mechanism. The signal transceiver 5 is clamped and fixed to the top of the turntable 3 through the first clamping mechanism, and the data collection camera 9 is clamped and fixed to the top of the horizontal adjustment table 7 through the second clamping mechanism, so that each data collection device is convenient for disassembly and assembly;

[0030] Inside the machine table 1, there is a lifting plate 11. The lifting plate 11 is driven by an electric hydraulic cylinder 10 to move up and down. At the four corners of the bottom end of the lifting plate 11, support legs 12 are fixed by bolts, and the bottom ends of the support legs 12 slide through to the lower part of the machine table 1 to provide support for the machine table 1. Through grooves adapted to the support legs 12 are symmetrically opened at the bottom end of the machine table 1 for the support legs 12 to pass through. At the center position of the bottom end of the machine table 1, a groove is opened, and a laser rangefinder 13 is fixed in the groove by bolts for measuring the distance between the ground and the machine table 1. The laser rangefinder 13 is connected to the PLC control system of the adaptive horizontal workbench. When it detects that the machine table 1 is lifted to an appropriate position, it drives the electric hydraulic cylinder 10 to stop working. The electric hydraulic cylinder 10 drives the lifting plate 11 to drive the support legs 12 to move up and down, and the laser rangefinder 13 measures the distance between the machine table 1 and the ground, so that the height of the machine table 1 can be adaptively adjusted according to actual use needs;

[0031] At the top of the machine table 1, there are two groups of transparent protective covers 14 distributed symmetrically left and right. At the top ends of the two groups of transparent protective covers 14, lifting handles are fixed. A sealing groove is opened at the right end of the left transparent protective cover 14, and a sealing strip adapted to the sealing groove is fixed at the left end of the right transparent protective cover 14. On the front and rear side walls of the machine table 1, two groups of slide plates 16 distributed symmetrically left and right slide through. The slide plates 16 are driven to move by a second motor 15 inside the machine table 1. Through grooves adapted to the slide plates 16 are opened on the front and rear side walls of the machine table 1 for the slide plates 16 to pass through. The slide plates 16 and the transparent protective covers 14 are clamped and fixed through an elastic clamping mechanism, which is convenient for the disassembly and assembly of the transparent protective covers 14. The second motor 15 drives the slide plates 16 on the left and right to move towards each other until the two groups of transparent protective covers 14 on the left and right are spliced and closed, so as to effectively protect the components at the top of the machine table 1.

[0032] A partition plate 17 is fixed inside the machine table 1 by bolts. There are two electric hydraulic cylinders 10. The two electric hydraulic cylinders 10 are symmetrically fixed on the partition plate 17 by bolts. The output end of the electric hydraulic cylinder 10 is located below the partition plate 17 and is fixed to the top end of the lifting plate 11 by bolts.

[0033] Inside the machine 1, there are two sets of horizontally moving plates 18 distributed symmetrically left and right. The front and rear sets of sliding plates 16 are respectively fixed to the front and rear ends of the horizontally moving plates 18 by bolts. A limiting rod 19 is fixed to the front side inside the machine 1, and the limiting rod 19 slidably penetrates through the horizontally moving plates 18. A first bidirectional lead screw 20 is rotatably connected to the rear side inside the machine 1 through a bearing, and the first bidirectional lead screw 20 is driven to rotate by a second motor 15. The two sets of horizontally moving plates 18 are threadedly sleeved on both sides of the first bidirectional lead screw 20 and the threaded connection directions are opposite. A first bevel gear 21 is fixed to the output shaft of the second motor 15, and a second bevel gear 22 is fixedly sleeved on the first bidirectional lead screw 20, and the second bevel gear 22 is engaged with the first bevel gear 21 in a matching manner. By driving the first bevel gear 21 to rotate by the second motor 15, the first bevel gear 21 drives the engaged second bevel gear 22 to rotate, and the second bevel gear 22 then drives the first bidirectional lead screw 20 to rotate, so that the horizontally moving plates 18 threadedly sleeved on both sides of the first bidirectional lead screw 20 move towards or in opposite directions, so as to drive the sliding plates 16 to move.

[0034] The elastic clamping mechanism includes a square frame 23 and an elastic plug 24. The square frame 23 is fixed to the outer walls of the front and rear sides of the transparent protective cover 14 by bolts. The elastic plug 24 slidably penetrates through the square frame 23 and the transparent protective cover 14. Sliding grooves 25 adapted to the sliding plates 16 are provided on the inner walls of the front and rear sides of the transparent protective cover 14. One end of the sliding plate 16 outside the machine 1 extends into the sliding grooves 25, so that the transparent protective cover 14 can move up and down along the sliding plate 16. A jack 26 is provided on one side of the sliding plate 16 close to the transparent protective cover 14, and the jack 26 is adapted to the elastic plug 24. The positioning and clamping between the transparent protective cover 14 and the sliding plate 16 are realized by inserting the elastic plug 24 into the jack 26. A retaining piece 27 is fixed to one side of the elastic plug 24 inside the square frame 23. A first limiting spring 28 is fixed between the retaining piece 27 and the inner wall of the side of the square frame 23 away from the transparent protective cover 14. The first limiting spring 28 is movably sleeved on the elastic plug 24. An elastic ejecting force is provided for the retaining piece 27 by the first limiting spring 28, so that the elastic plug 24 can automatically rebound and insert into the jack 26.

[0035] The output shaft of the first motor 2 is vertically upward and is fixed with a driving gear 29. A driven gear ring 30 is fixedly sleeved on the outer wall of the turntable 3, and the driven gear ring 30 is engaged with the driving gear 29 in a matching manner. A support shaft 31 is fixed to the bottom end of the turntable 3, and the support shaft 31 is rotatably connected to the top end of the machine 1. By driving the driving gear 29 to rotate by the first motor 2, the driving gear 29 drives the engaged driven gear ring 30 to rotate, and the driven gear ring 30 then drives the turntable 3 to rotate.

[0036] The first clamping mechanism includes a pull rod 32 and a first clamping plate 33. There are two groups of pull rods 32, which respectively slide through the two groups of support plates 4. At the opposite ends of the two groups of pull rods 32, pull rings are fixed respectively for pulling the pull rods 32. There are two groups of first clamping plates 33, which are respectively fixed at the opposite ends of the two groups of pull rods 32. At the opposite ends of the two groups of first clamping plates 33, sleeves 34 are symmetrically fixed in an up-and-down distribution. On the opposite side walls of the two groups of support plates 4, first sliding rods 35 are symmetrically fixed and slide through into the sleeves 34. A second limit spring 36 is fixed between the inner wall of the sleeve 34 far from the first clamping plate 33 and the first sliding rod 35. Through the action of the second limit spring 36, the two groups of first clamping plates 33 can automatically clamp the signal transceiver 5.

[0037] The second clamping mechanism includes a second bidirectional lead screw 37 and threaded blocks 38. The second bidirectional lead screw 37 is rotatably connected to the inside of the horizontal adjustment table 7 through bearings. The right end of the second bidirectional lead screw 37 passes through the outside of the horizontal adjustment table 7 through bearings and is fixed with a turntable. There are two groups of threaded blocks 38. The two groups of threaded blocks 38 are respectively threadedly sleeved on both sides of the second bidirectional lead screw 37 and have opposite threading directions. The tops of the threaded blocks 38 slide through above the horizontal adjustment table 7 and are fixed with second clamping plates 39. Through grooves adapted to the threaded blocks 38 are opened at the top of the horizontal adjustment table 7 for the threaded blocks 38 to pass through. By rotating the turntable to drive the second bidirectional lead screw 37 to rotate, the threaded blocks 38 threadedly sleeved on both sides of the second bidirectional lead screw 37 move towards each other, and drive the second clamping plates 39 to clamp and limit the data acquisition camera 9.

[0038] The cylinder 6 is fixed to the top of the right support plate 4 by bolts. The top of the left support plate 4 is fixed with a support rod 40 by bolts. The top of the support rod 40 is hinged to the bottom end of the horizontal adjustment table 7 through a hinge member, so that the horizontal adjustment table 7 can tilt and rotate around the top of the support rod 40. The output end of the cylinder 6 is hinged with a hinge seat 41. The top of the hinge seat 41 is fixed with a sliding sleeve 42. A groove is opened at the bottom right of the horizontal adjustment table 7 and a second sliding rod 43 is fixed in the groove. The sliding sleeve 42 is slidably sleeved on the second sliding rod 43. By driving the right side of the horizontal adjustment table 7 to lift or lower through the cylinder 6, the levelness adjustment of the horizontal adjustment table 7 is realized.

[0039] When the adaptive horizontal workbench for geographic information data collection is in use, first move the machine table 1 to the area to be collected. First, use the electric hydraulic cylinder 10 to drive the lifting plate 11 to drive the support leg 12 to move up and down to adjust the support height of the machine table 1. At the same time, use the laser rangefinder 13 to measure the distance between the machine table 1 and the ground until the support height of the support leg 12 for the machine table 1 reaches the actual requirement. Then, use the electronic level 8 to detect the levelness of the horizontal adjustment table 7. When it is detected that the horizontal adjustment table 7 is in a skew state, start the cylinder 6 to drive the horizontal adjustment table 7 to tilt and adjust until the data collection camera 9 at its top is kept horizontal. Subsequently, start the data collection camera 9 to work, collect the surrounding geographic information data, and send the collected geographic information data to the remote control terminal through the signal transceiver 5 to realize the collection work of the geographic information data;

[0040] In the initial state, the two groups of transparent protective covers 14 are in a separated and unfolded state, and the upper surface of the transparent protective cover 14 is on the same horizontal plane as the upper surface of the machine table 1. When there are harsh weather conditions such as rain, snow, wind and sand in the outdoor environment, first lift the transparent protective cover 14 upward and use the elastic clamping mechanism to clamp and position between the transparent protective cover 14 and the sliding plate 16. Then, use the second motor 15 to drive the sliding plates 16 on the left and right to move towards each other until the two groups of transparent protective covers 14 are spliced and closed with each other, so as to effectively protect the components at the top of the machine table 1 with the two mutually butted transparent protective covers 14, making it not easily damaged due to harsh weather conditions such as rain, snow, wind and sand.
