Description

Technical Field

[0001] The present invention belongs to the technical field of geographic information collection, and specifically relates to a geographic information surveying and collecting device for national land space planning. Background Art

[0002] National land space planning refers to the planning work of rationally allocating, scientifically utilizing and protecting land resources according to the needs of comprehensive economic and social development. Geographic information survey and collection equipment plays an important role in national land space planning. Geographic information survey and collection equipment mainly includes global satellite navigation systems (such as GPS, Beidou, etc.), remote sensing instruments and bottom-mounted total stations for coordinated use and completion of geographic information survey and collection.

[0003] The prior art geographic information survey and collection equipment for land space planning usually uses a drone equipped with a total station. During the flight in the air, the total station survey port arranged downward is used to survey and collect the geographic information below. After the drone is lowered, the drone is placed on a fixed tripod, and the total station is disassembled and adjusted and then additionally arranged on the ground. The geographic information collection above the static ground is achieved by adding a total station fixed on the tripod. However, the former requires the disassembly or re-adjustment of the survey direction of the carried total station after the drone lands, which is troublesome to operate and inconvenient to use. The latter requires the purchase of an additional fixed static total station for geographic information detection, which has a high actual investment cost. The maintenance and carrying and transportation of the two sets of survey machines are relatively troublesome, and the application effect is not good. It is inconvenient to conduct geographic information survey and collection for land space planning, and the use effect is not good.

[0004] In addition, in the prior art, when a single drone is used to carry a total station for aerial survey, after the aerial survey is completed, when it falls back to the ground and is assembled for low-level ground survey, the dust in the air adheres to the surface of the total station due to the relative movement of the air during the flight, causing the survey lens group and the total station instrument to be seriously dusty, requiring cleaning for subsequent effective testing. However, the cleaning method currently used has a limited cleaning range, and manual assistance is required for all-round cleaning, which is inefficient, affects the work efficiency of continuous survey operations, and has poor use effect.

[0034] First embodiment: When the unmanned aerial vehicle 1 takes off, the survey port of the total station 3 at the bottom is pointed vertically downward, and during the flight in the air, the land survey is performed downward. When the unmanned aerial vehicle 1 lands at a height near the fixed tripod, the air pump 191 in the controllable air supply assembly 19 is started, and the gas is input into the No. 1 hole 16 through the air pipe 192, and the gas enters the interior of the internal cavity 5. As the gas pressure in the right-angle space between the No. 3 folding plate 8 and the No. 1 folding plate 6 in the lower part of the internal cavity 5 increases, the high-pressure gas pushes the No. 1 folding plate 6 to rotate upward, and at the same time drives the rotating shaft 4 The rotating shaft 4 rotates, and at the same time, the total station 3 in the bottom seat 2 is driven to swing accordingly, so that the bottom survey port of the total station 3 rotates upward from the bottom to the horizontal, and at the same time, the No. 1 folding plate 6 is upwardly embedded in the No. 3 folding plate 8 located above, and as the rotating shaft 4 drives the connecting shaft 12 fixed on the end surface to rotate, the No. 1 gear 13 on the connecting shaft 12 rotates, thereby rotating the No. 2 gear 145 in the meshing connection reverse rotation assembly 14, so that the No. 2 gear 145 sleeved on the fixed shaft 144 through the bearing (not shown in the figure) rotates. The gear ring 142 meshing with the outside is driven to rotate, so that the gear ring 142 drives the rotating ring 141 to rotate, and during the rotation process, the rotating ring 141 drives the purge assembly 15 connected to the outer surface to rotate, and the actual purge assembly 15 rotates downward from the horizontal direction, and the total station 3 rotates from bottom to top at the same time, and the purge assembly 15 is synchronously started when the controllable air supply assembly 19 is started, so that at the moment the total station 3 rotates, the purge assembly 15 blows and cleans along the outside of the total station 3, and as the total station 3 rotates upward, the purge assembly 15 5 rotates downward, and the purge assembly 15 completes the purge of the lateral side, bottom and other side of the total station 3 in sequence. At this time, the survey port of the total station 3 completes the horizontal adjustment, and the control valve 193 is closed to complete the pressure maintenance and maintain stability. When it is necessary to adjust the survey angle of the total station 3 according to the survey situation, the control valve 193 is started and the instantaneous opening and closing action is performed to gradually release the air in the internal cavity 5. With the release action, the No. 1 folding plate 6 in the internal cavity 5 is gradually reset, and at the same time, the rotating shaft 4 is driven to rotate and reset to a certain angle, so that the angle of the total station 3 changes.

[0035] First, ventilation is performed by utilizing the controllable air supply assembly 19, and the gas is introduced into the internal cavity 5 in cooperation with the No. 1 hole 16, and the No. 1 folding plate 6 is pushed to rotate, and at the same time, the rotation of the rotating shaft 4 is cooperated to complete the rotation adjustment of the total station 3, and the shape adaptation effect of the No. 3 folding plate 8 and the No. 1 folding plate 6 is made to be accurately embedded in the No. 3 folding plate 8 after rotating 90°, completing the precise 90° rotation adjustment, thereby realizing the adjustment of the total station 3 from the bottom survey angle to the horizontal, and after lowering the unmanned vehicle body 1, the angle adjustment of the total station 3 is directly completed, thereby realizing the installation of the ground tripod and conducting the survey of ground geographic information, reducing the manual disassembly and adjustment steps, and automatically adjusting quickly and accurately, and at the same time, cooperating with the instantaneous opening and closing of the control valve 193, the deflation of the introduced gas is completed, so that the actual angle can be conveniently adjusted according to the actual ground survey requirements, and the actual geographic information survey is convenient and effective, and the switching from aerial survey to ground survey is rapid and stable, and the actual adjustment accuracy is high, the range is wide, and the use effect is good.

[0036] In addition, by sleeve-arranging a No. 1 gear 13 on the end face of the rotating shaft 4 through the connecting shaft 12, and cooperating with the arrangement of the reverse rotating component 14, the rotating shaft 4 can be rotated and the total station 3 can be rotated from bottom to top under the air supply effect, while the reverse rotating component 14 is used to realize the rotation of the purge component 15 from horizontal downward, and in cooperation with the purge effect in the purge component 15, after completing the aerial flight survey, the total station 3 and the purge component 15 that rotate in opposite directions are used to complete the purge cleaning of the two sides and the survey port of the total station 3, which greatly improves the actual purge cleaning range, and while the purge is completed within the range automatically, effective cleaning is achieved to avoid a large amount of dust and impurities adhering to the surface after the high-altitude flight survey and affecting the subsequent ground level survey, the actual purge cleaning range is wide, the cleaning is automatic and the timing is good, the cleaning is achieved during the descent of the unmanned aerial vehicle body 1, and the assembly with the fixed tripod is directly performed, saving intermediate time and comprehensively improving the efficiency of comprehensive geographic information survey.

[0037] Second embodiment: When the unmanned aerial vehicle body 1 is lowered and the controllable air supply assembly 19 is started, as the pressurized air pushes the No. 1 folding plate 6 to swing upward, the upper space of the No. 1 folding plate 6 is compressed, so that the filled lubricating oil quickly flows to the other side through the through hole 9, so that the oil pressure on the other side of the internal cavity 5 increases, thereby transmitting the liquid pressure to the inside of the amplifying pushing assembly 21 through the No. 2 hole 17, so that the movable rod 215 moves upward, and drives the movable plug 213 to move upward to compress the lubricating oil in the amplifying cylinder 212, and the No. 3 spring 214 is compressed, the internal oil pressure of the connecting frame 201 in the support assembly 20 increases, and the support leg 203 in the support assembly 20 is pushed downward by the oil pressure, so that the bottom of the support leg 203 passes over the bottom surface of the bottom seat 2 and moves to the bottom, and contacts with the landing platform to complete the landing.

[0038] First, by again utilizing the controllable air supply assembly 19 to supply pressurized air inside the internal cavity 5, while coordinating with the descent of the unmanned aerial vehicle 1, the No. 1 folding plate 6 rotates and moves upward, completing the angle adjustment of the total station 3, and coordinating with the rotation of the No. 1 folding plate 6 to further compress the lubricating oil on the other side of the internal cavity 5, and coordinating with the increase in lubricating oil pressure, the movable rod 215 in the amplification push assembly 21 moves under the push of the hydraulic pressure, thereby quickly compressing the lubricating oil inside the amplification cylinder 212, so that the oil pressure in the support assembly 20 is synchronously increased, and the support legs 203 are lowered downward to ensure that the support legs are retracted during flight, reduce the exposed area, reduce wind resistance, and shrink the overall upper and lower structure lengths, concentrate the center of gravity, thereby improving the flight stability of the unmanned aerial vehicle 1, and at the same time, cooperate with the synchronously raised and retracted support legs 203 during the synchronous flight process to avoid the total station 3 being disturbed by the outer lower support legs when surveying downward, avoid the survey screen being blocked, and further improve the survey quality.

On the one hand, precise limiting is achieved to ensure that the rotation is 90° after the rotation limit, so that the total station 3 can be rotated from a vertical downward position to a horizontal horizontal position. In addition, by controlling the filling of lubricating oil and cooperating with the opening of the through hole 9, part of the lubricating oil is squeezed during the rotation and upward movement of the No. 1 folding plate 6, compressing the actual space and compressing the lubricating oil into the No. 2 hole 17, providing the action power of the support assembly 20, wherein the guide arc rod 10 guides the rotation movement of the No. 2 folding plate 7, and cooperates with the elasticity of the No. 1 spring 11 to facilitate automatic resetting.

The pressure relief hole at the bottom of the amplifying cylinder 212 maintains the air pressure balance under movement.

[0047] like Figure 1 , Figure 2 and Figure 5 As shown, the purge assembly 15 includes a swing frame 151, a mounting hole 152 and a fan 153. The swing frame 151 is located on the outside of the bottom seat 2. The swing frame 151 is fixedly connected to the rotating ring 141. The mounting hole 152 is opened on the front side of the swing frame 151, and the fan 153 is arranged in the mounting hole 152.

[0048] During use, the purge assembly 15 is used to cooperate with the counter-movement of the total station 3 to complete comprehensive purge cleaning.

[0049] Working principle and use process: When the unmanned aerial vehicle 1 takes off, the survey port of the total station 3 at the bottom is vertically downward, and during the flight in the air, the land survey is carried out downward. When it lands at a height near the fixed tripod, the air pump 191 in the controllable air supply component 19 is started, and the gas is input into the No. 1 hole 16 through the air pipe 192, and the gas enters the interior of the internal cavity 5. As the gas pressure in the right-angle space between the No. 3 folding plate 8 and the No. 1 folding plate 6 in the lower part of the internal cavity 5 increases, the high-pressure gas pushes the No. 1 folding plate 6 to rotate upward, and at the same time drives the rotating shaft 4 to rotate. As the rotating shaft 4 rotates, the total station 3 in the bottom seat 2 is driven to swing, so that the bottom survey port of the total station 3 rotates from the bottom upward to the horizontal, and at the same time the No. 1 folding plate 6 It is embedded upward in the third folding plate 8 located above, and as the rotating shaft 4 drives the connecting shaft 12 fixed on the end surface to rotate, the first gear 13 on the connecting shaft 12 rotates, thereby causing the second gear 145 in the meshing reverse rotating component 14 to rotate, so that the second gear 145 sleeved on the fixed shaft 144 through a bearing (not shown in the figure) drives the external meshing gear ring 142 to rotate, so that the gear ring 142 drives the rotating ring 141 to rotate, and during the rotation process, the rotating ring 141 drives the purge component 15 connected to the outer surface to rotate, and the actual purge component 15 rotates downward from the horizontal direction, and at the same time the total station 3 rotates from bottom to top, and the purge component is started synchronously when the controllable air supply component 19 is started. 15, so that the total station 3 rotates at the moment, the purge component 15 purges and cleans along the outside of the total station 3, and as the total station 3 rotates upward and the purge component 15 rotates downward, the purge component 15 completes the purge of the lateral side, bottom and the other side of the total station 3 in sequence. At this time, the survey port of the total station 3 completes the horizontal adjustment, the control valve 193 is closed, and the pressure is maintained to maintain stability. When it is necessary to adjust the survey angle of the total station 3 according to the survey situation, the control valve 193 is started and the instantaneous opening and closing action is performed to gradually deflate the internal cavity 5. With the deflation action, the No. 1 folding plate 6 in the internal cavity 5 is gradually reset, and at the same time, the rotating shaft 4 is driven to rotate and reset to a certain angle, so that the angle of the total station 3 changes; when the unmanned vehicle body 1 is lowered and started, the control valve 193 can be When the air supply assembly 19 is controlled, as the pressurized air pushes the No. 1 folding plate 6 to swing upward, the upper space of the No. 1 folding plate 6 is compressed, so that the filled lubricating oil quickly flows to the other side through the through hole 9, so that the oil pressure on the other side of the internal cavity 5 increases, and the liquid pressure is transmitted to the interior of the amplifying pushing assembly 21 through the No. 2 hole 17, so that the movable rod 215 moves upward, and drives the movable plug 213 to move upward to compress the lubricating oil in the amplifying cylinder 212, and the No. 3 spring 214 is compressed, the internal oil pressure of the connecting frame 201 in the support assembly 20 increases, and the support leg 203 in the support assembly 20 is pushed downward by the oil pressure, so that the bottom of the support leg 203 passes over the bottom surface of the bottom seat 2 and moves to the bottom, and contacts with the landing platform to complete the landing.
