Description

A geographic information survey and collection device for national land space planning

Technical Field

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

Background technique

Geographic information survey and collection equipment for national space planning is a key tool in the field of modern surveying and mapping and geographic information. It can provide high-precision geographic location information and is the basis for surveying and collecting geographic data. By measuring the horizontal and vertical angles and distances, the three-dimensional coordinates of the target point are calculated for drawing topographic maps, building layout, deformation monitoring, etc., providing accurate geographic data for planning. Equipment tends to integrate multiple sensors to achieve multifunctional and intelligent surveying. Geographic information survey and collection equipment for national space planning plays a key role in providing high-precision and comprehensive geographic data, supporting the scientific and rational use of land resources and planning decisions.

A Chinese patent with application number CN202310430658.5 discloses a geographic information survey and collection device for land space planning, including a collection box, a collection cavity is provided inside the collection box, and movable grooves are provided inside the collection box and on both sides of the collection cavity, and a first servo motor is provided at the top of the inner cavity of the movable groove, and a threaded column is provided at the output end of the first servo motor, and a limit block is threadedly connected to the outer side of the threaded column. The geographic information survey and collection device for land space planning is provided with an unmanned aerial vehicle body, a collection box and a connecting platform, and can use a total station module to collect high-altitude data and ground data, so that the device has a wide range of uses and more functions. At the same time, the connecting platform and the collection box can be separated, which is convenient for carrying the device for movement, thereby facilitating geographic information survey and collection work.

Usually, when using drones to survey geographic information, the drones operate at high altitudes. The influence of high-altitude wind direction and uncertain flight speed causes deviations in the exploration angle of the total station, resulting in inaccurate measurement information. In addition, it is impossible to conduct high-altitude and ground surveys on the same device at the same time, resulting in more equipment being carried in the field, which in turn is inefficient. For some comprehensive measuring equipment, after the drone survey is completed, a lot of adjustment work is required for subsequent ground surveys, and the inability to switch efficiently leads to low efficiency.

Compared with the prior art, the present invention has the following beneficial effects:

(1) The present invention adjusts the structural design of the spherical panel of the structure to form a spherical inner cavity, so that the spherical total station can be slidably connected to the spherical panel, thereby flexibly adjusting the angle of the total station.

(2) The present invention adopts a matching design of a rotating bottom ring and an annular groove. When it is necessary to survey the ground, the rotating bottom ring is inserted into the annular groove, and the left and right angles of the total station are adjusted and measured by rotating the adjustment structure and the rotating bottom ring. By rotating the balance structure on one side up and down, the objective lens slides on the corresponding slideway so that the objective lens faces forward, and then the balance structure on the other side is rotated so that the limit plate of the balance structure locks the ball panel, thereby fixing the angle.

When it is necessary to conduct ground geographic information survey, the rotating bottom ring is inserted into the annular groove, and the double-bevel limiting head of the limiting member is squeezed by the double-chamfered structure of the rotating bottom ring. Through the force of the inclined surface, the limiting member can easily compress the spring and retract into the telescopic groove. After the rotating bottom ring is inserted into the annular groove, the limiting head of the limiting member extends out of the telescopic groove to perform preliminary limiting on the rotating bottom ring, which is also beneficial for rotation adjustment. If it is necessary to move the ground survey position, the rotating bottom ring is fixed by the limiting screw for further limiting, and then the point is moved to conduct ground geographic information survey; when it is necessary to conduct high-altitude survey, the rotating bottom ring is pulled out, and the rotating bottom ring can be easily taken out through the double-chamfered structure of the rotating bottom ring and the double-bevel limiting head of the limiting member, thereby realizing flexible switching between ground survey and high-altitude survey.

(4) The present invention realizes horizontal adjustment of the base through the structural design of the first support frame and the second support frame, and through the angle adjustment of the first support frame and the second support frame, in combination with a pancake-shaped level; the second slide groove can be structurally designed with the first slide groove, so that when switching to ground survey, the flexible plastic cloth coated with a fluorescent layer is unfolded on the first slide groove of the first support frame, so that the landing platform in the area where the base is located is larger and more conspicuous, which is convenient for the UAV to land, thereby improving the work efficiency of survey switching and reducing the risk of equipment damage caused by improper landing position of the UAV; when the surveying is completed, the second support frame is folded so that the second support frame is located above the first support frame, and then the flexible plastic cloth is slid into the second slide groove of the second support frame, and the equipment is stored by fixing the fixing hole, thereby protecting the UAV and the total station and preventing equipment damage.

In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with embodiments. Of course, the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

Although the steps in the present invention are arranged with numbers, they are not used to limit the order of the steps. Unless the order of the steps is clearly stated or the execution of a certain step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and/or" used in this article involves and covers any and all possible combinations of one or more of the associated listed items.

Example

As shown in FIG. 1 to FIG. 8 , a geographic information survey and collection device for land space planning includes a total station 200 and an adjustment structure 400, wherein the total station 200 is installed inside the adjustment structure 400; a bottom frame is movably installed at the bottom of the adjustment structure 400;

As shown in FIG3 , the adjustment structure 400 includes four support columns 410, and spherical panels 420 are fixed on opposite side walls of the support columns 410. The four spherical panels 420 together form a spherical inner cavity 421, and the top and bottom of the inner cavity 421 are both open; the bottom ends of the support columns 410 are commonly fixedly connected to a rotating bottom ring 430, and the outer side and inner side of the rotating bottom ring 430 are both set as a protruding double chamfered structure 431; the top ends of the support columns 410 are commonly fixedly connected to the drone 100;

It is worth noting that the upper and lower chamfers of the double chamfer structure 431 can be rounded or beveled.

The UAV 100 and the total station 200 are both existing mature technologies. The UAV 100 can be flown through an automated system, remote control or a preset flight plan. The UAV is usually composed of the aircraft itself, a remote control or a ground station, a sensor, a communication system, etc. The total station 200 is a measuring instrument, which is mainly used to measure coordinates in geographic space. It is widely used in civil engineering, construction engineering, geological surveying and other fields. It will not be described in detail here.

As shown in Figure 4, the total station 200 is a spherical structure. The total station 200 is arranged in an inner cavity 421 and is slidably connected to a spherical panel 420. An objective lens 220 and an eyepiece 210 are relatively arranged on the total station 200. The objective lens 220 is located at the bottom of the inner cavity 421, and the eyepiece 210 is located at the top of the inner cavity 421.

It is worth noting that the center of gravity of the total station 200 is the same as the center of gravity of the spherical structure. The center of gravity position can be achieved by making an internal layout of the total station 200, which will not be described in detail here.

The present invention adjusts the structural design of the spherical panel 420 of the structure 400 so that the spherical panel 420 forms a spherical inner cavity, thereby enabling the spherical total station 200 to be slidably connected to the spherical panel 420, thereby flexibly adjusting the angle of the total station 200.

It is worth noting that the contact surface material of the total station 200 and the ball panel can be selected to make the sliding effect between them smoother, and the specific material is not further limited.

Furthermore, four threaded openings 230 are evenly opened around the total station 200, and a balancing structure 300 is screwed on the threaded openings 230; the balancing structure 300 includes a screw rod 320, one end of the screw rod 320 is fixedly connected to a balancing ball 310, and the other end of the screw rod 320 is screwed to the threaded openings 230, and a limit plate 330 is fixed on the screw rod 320;

Through the cooperation of the balancing structure 300, the balancing balls 310 of the four balancing structures 300 act on the spherical total station 200, so that the objective lens 220 of the total station 200 is always facing downward. When the drone 100 accelerates or decelerates to change the flight posture, or changes its posture due to the action of wind, it does not affect the angle direction of the objective lens 220 of the total station 200, so that the drone 100 will not affect the operation of the total station 200 when flying in the sky, thereby improving the accuracy of high-altitude surveying.

It is worth noting that the weight of the balancing ball 310 can be determined by the power configuration of the specific drone 100 and the weight of the total station 200, and can be selected according to actual conditions, which will not be further explained here.

A slideway 422 is formed between adjacent spherical panels 420, the balancing structure 300 is located on the corresponding slideway 422, the limiting plate 330 is located on the outer side of the spherical panel 420, the outer diameter of the limiting plate 330 is greater than the width of the slideway 422, and the outer diameters of the eyepiece 210 and the objective lens 220 are both smaller than the width of the slideway 422, thereby ensuring that the eyepiece 210 and the objective lens 220 can slide in the slideway 422, and at the same time, after the screw 320 is tightened, the limiting plate 330 can press the spherical panel 420 for limiting.

As shown in Figure 6, further, the base frame also includes a base 600, and the base 600 includes a chassis 610. The chassis 610 is provided with an annular groove 620, and the annular groove 620 is matched and movably connected with the rotating bottom ring 430; a limiting structure 500 is installed on the annular groove 620 for limiting the rotating bottom ring 430.

The present invention adopts the matching design of rotating the bottom ring 430 and the annular groove 620. When it is necessary to survey the ground, the rotating bottom ring 430 is inserted into the annular groove 620, and the left and right angles of the total station 200 are adjusted and measured by rotating the adjustment structure 400 and the rotating bottom ring 430; by rotating the balance structure 300 on one side up and down, the objective lens 220 slides on the corresponding slide 422, so that the objective lens 220 faces forward, and then by rotating the balance structure 300 on the other side, the limit plate 330 of the balance structure 300 locks the ball panel 420, so that the angle is fixed. When it is necessary to adjust and measure the upper and lower angles, the balance structure 300 is unscrewed to adjust and measure, thereby realizing the survey of ground geographic information.

Furthermore, a pancake-shaped level 630 is fixed in the middle of the top of the chassis 610. The pancake-shaped level 630 is a liquid level that can display the horizontal condition of the chassis 610, making it convenient to keep the chassis 610 in a horizontal state through the pancake-shaped level 630. At the same time, the position of the total station 200 can also be understood through the relative position of the balancing structure 300 and the pancake-shaped level 630.

Furthermore, a plurality of expansion slots 621 are symmetrically provided on the inner side wall of the annular slot 620 , and the slot openings of the expansion slots 621 are double-bevel slots with decreasing widths; the double-bevel slots make the slot opening width smaller than the width inside the expansion slot 621 , which facilitates positioning.

The limiting structure 500 includes a spring 530 and a limiting member 520, both of which are located in the telescopic groove 621; one end of the spring 530 is fixedly connected to the inner bottom end of the telescopic groove 621, and the other end of the spring 530 is fixedly connected to the limiting member 520; the limiting member 520 is slidably connected to the telescopic groove 621, and the end of the limiting member 520 away from the spring 530 is a double-bevel limiting head with a continuously decreasing width, and the limiting head extends into the annular groove 620.

It is worth noting that the double-beveled limit head of the limit member 520 matches the double-beveled notch of the telescopic slot 621 , and the bevel angles can be the same, so as to reduce the telescopic resistance.

Furthermore, the limiting structure 500 also includes a limiting screw 510, and a plurality of threaded holes are opened on the outer side of the chassis 610, the threaded holes are located below the telescopic groove 621, and the threaded holes are connected to the annular groove 620; the limiting screw 510 is threadedly connected to the threaded hole and passes through the threaded hole, so as to fix the rotating bottom ring 430.

The present invention adopts the structural design of the limiting structure 500. When ground geographic information survey is required, the rotating bottom ring 430 is inserted into the annular groove 620. The double chamfered structure 431 of the rotating bottom ring 430 squeezes the double inclined limiting head of the limiting member 520. The limiting member 520 can easily compress the spring 530 through the force of the inclined surface, thereby shrinking it into the telescopic groove 621. When the rotating bottom ring 430 is inserted into the annular groove 620, the limiting head of the limiting member 520 extends out of the telescopic groove 621 to squeeze the rotating bottom ring 430. It performs preliminary limiting and is also conducive to rotation adjustment. If the ground survey position needs to be moved, the rotating bottom ring 430 is fixed by the limiting screw 510 for further limiting, and then the point is moved to conduct ground geographic information survey; when it is necessary to survey at high altitude, the rotating bottom ring 430 is pulled out, and the rotating bottom ring 430 can be easily taken out through the action of the double chamfered structure 431 of the rotating bottom ring 430 and the double bevel limiting head of the limiting member 520, thereby realizing flexible switching between ground survey and high altitude survey.

Through the cooperation of the limiting structure 500 and the adjusting structure 400 of the present invention, the UAV 100 and the total station 200 can be quickly separated from the base 600 to perform high-altitude precise surveys, and can also be quickly combined with the base 400 when ground surveys are required, thereby performing ground surveys by realizing flexible angle control.

As shown in Figures 5 and 6, further, a support frame 700 is fixed to the bottom of the base 600, and the support frame 700 includes a first support frame 710 and a second support frame 720. There are four first support frames 710, which are horizontally arranged and evenly fixed on the bottom of the base 600 in a circumferential direction; one end of the first support frame 710 away from the base 600 is hinged to the second support frame 720, and one end of the second support frame 720 is fixed with a supporting foot 722.

The present invention realizes the horizontal adjustment of the base 600 through the structural design of the first support frame 710 and the second support frame 720, by adjusting the angles of the first support frame 710 and the second support frame 720, and cooperating with the round pancake-shaped level 630;

It is worth noting that the lengths of the first support frame 710 and the second support frame 720 are not specifically limited and can be adaptively adjusted according to the size of the human body and the drone, and are not specifically limited here.

As shown in Figures 7 and 8, further, both sides of the first support frame 710 are provided with a first slide groove 711, the first slide groove 711 is an L-shaped structure, the first slide groove 711 is arranged upward near the notch of the second support frame 720, and a plurality of sliding members 712 are slidably connected to the first slide groove 711, and a flexible plastic sheet 800 is fixedly connected to the sliding members 712 on one side of two adjacent first support frames 710, and the surface of the flexible plastic sheet 800 is coated with a fluorescent layer.

It is worth noting that the flexible plastic sheet 800 is flexible and has certain expansion and contraction and folding capabilities. The specific material can be selected conventionally and will not be described in detail here.

Furthermore, the sliding member 712 close to the base 600 may be fixedly connected to the first support frame 710 , thereby facilitating the extension and folding of the flexible plastic sheet 800 .

Furthermore, second slide grooves 721 are provided on both sides of the second support frame 720 . When the second support frame 720 rotates to above the first support frame 710 , the second slide grooves 721 can be connected to the first slide grooves 711 .

Furthermore, a fixing head 713 is fixedly provided on the sliding member 712 which is farthest from the base 600 , and a first fixing hole is provided on the fixing head 713 ; and a second fixing hole 723 is provided on the supporting foot 722 .

Through the structural design of the second slide groove 721 and the first slide groove 711, when switching to ground survey, the flexible plastic cloth 800 coated with the fluorescent layer is unfolded on the first slide groove 711 of the first support frame 710, so that the landing platform in the area where the base 600 is located is larger and the fluorescent layer is more conspicuous, which is convenient for the UAV 100 to land, thereby further improving the working efficiency of high-altitude ground survey switching and reducing the risk of equipment damage caused by improper landing position of the UAV 100; when the surveying is completed, the second support frame 720 is folded so that the second support frame 720 is located above the first support frame 710, and then the flexible plastic cloth 800 is slid into the second slide groove 721 of the second support frame 720, and the equipment is stored by fixing between the fixing holes, thereby protecting the UAV 100 and the total station 200 to prevent equipment damage.

It is worth mentioning that the fixing holes can be fixed by fixing bolts or fixing ropes, which are not further limited here. After fixing, a cover can be placed on the top of the device for protection. After storage, it can be placed anywhere waiting for the next use by the staff. The fluorescent layer is more conducive to the staff's search and positioning, which is conducive to the field use of the equipment.

The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and changes without departing from the creative concept of the present invention, and these all fall within the protection scope of the present invention.
