Description

Technical Field

[0001] The utility model relates to the technical field of geological survey, in particular to a remote sensing geological survey device. Background Art

[0002] Conducting field surveys with hyperspectral survey instruments and enriching the spectral database of ground objects is an important basic work for quantitative ground inversion in aerospace hyperspectral or multispectral remote sensing. Relevant scientific research units in the field of remote sensing spend huge manpower and material resources on field surveys every year. However, during the field surveys, it is found that some ground objects are difficult to approach, such as in swamps. In addition, some ground objects, such as trees, are relatively high and can only be collected by ladders, which is dangerous. In order to solve this problem, most of the current geological surveys are carried out by drones mounted on hyperspectral survey instruments.

[0003] With existing remote sensing geological survey equipment, when the drone takes off and flies, the raised mud and dust can easily adhere to the hyperspectral survey instrument, thus affecting the accuracy of the data collected by the hyperspectral survey instrument. Sand and gravel can hit the hyperspectral survey instrument, causing damage to the lens. At the same time, when the drone is flying at low altitude, it may scratch against tree branches or collide with birds, causing damage to the drone. When the drone is forced to land in complex ground conditions such as water, swamps, and mud, the lack of effective support on the bottom causes the drone to sink and cannot be retrieved. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a remote sensing geological survey device to solve the technical problems of impaired data collection accuracy of the hyperspectral survey instrument, damage to the equipment and damage to the safety of the drone itself due to environmental factors during the take-off, flight and forced landing of the drone.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a remote sensing geological survey device, comprising an unmanned aerial vehicle body, a protective mechanism and a hyperspectral survey instrument, wherein a support column is arranged at the bottom of the unmanned aerial vehicle body, a rotating rod is rotatably connected to the bottom of the support column through a universal ball seat, a bottom of the rotating rod is fixedly connected to a bottom plate, an outer surface of the bottom plate is connected to a rope winding column through a first steel rope, a motor is arranged at the top of the unmanned aerial vehicle body, and an output end of the motor is connected to the rope winding column;

[0006] The protection mechanism comprises a second steel rope, one end of which is connected to a sponge sheet, one side of which is fixedly connected to a spring sleeve rod, one end of which is fixedly connected to an outer shell, and an inner wall of the outer shell is provided with a sliding groove.

[0007] By adopting the above technical solution, the support column plays the role of connecting the UAV body and the base plate, providing a stable support structure, which ensures that the base plate and the surveying equipment on it can be stably fixed under the UAV and will not be affected by turbulence during flight.

[0008] Furthermore, the second steel rope is fixedly connected to the first steel rope, and two first steel ropes are provided, and the two first steel ropes are symmetrically arranged along the central axis of the drone body.

[0009] By adopting the above technical solution, the second steel rope is fixedly connected to the first steel rope, which plays the role of connecting and transmitting tension.

[0010] Furthermore, the spring sleeve rods are provided in two groups, and each group of the spring sleeve rods is provided with two.

[0011] By adopting the above technical solution, the spring sleeve rod is used to automatically pull back the sponge sheet. During the operation of the remote sensing geological survey device, the sponge sheet is pulled to wipe the lens of the hyperspectral survey instrument. When the base plate is lowered, the spring sleeve rod uses its internal spring force to automatically pull back the sponge sheet.

[0012] Furthermore, a plurality of through holes are provided on the outer surface of the bottom plate, and the plurality of through holes are evenly and equidistantly arranged in a filling array, and a reflective coating is provided on the bottom of the bottom plate.

[0013] By adopting the above technical solution, the reflective coating is located at the bottom of the base plate to reduce the interference of light on the hyperspectral survey instrument. At the same time, the reflected light can disperse flying birds and prevent collisions.

[0014] Furthermore, four rotating rods are provided, and the four rotating rods are evenly and equidistantly arranged in a rectangular array, and damping springs are provided inside the rotating rods.

[0015] By adopting the above technical solution, the rotating rod plays a key supporting and stabilizing role in the remote sensing geological survey device. It is evenly and equidistantly arranged in a rectangular array, which can ensure that the base plate has sufficient stability and bearing capacity when unfolded, and can evenly disperse gravity when landing on complex ground, such as water, swamps, mud, etc.

[0016] Furthermore, two sponge sheets are provided, and the two sponge sheets are adapted to the slide groove.

[0017] By adopting the above technical solution, the sponge sheet can wipe the lens of the hyperspectral survey instrument during the flight to ensure the clarity of the survey.

[0018] Furthermore, a GPS signal generator is provided on one side of the motor, and the GPS signal generator is connected to an external console via an electrical signal.

[0031] The following describes an embodiment of the utility model based on its overall structure.

[0032] A remote sensing geological survey device, such as Figure 1-Figure 4 As shown, it includes a drone body 1, a protection mechanism 10 and a hyperspectral survey instrument 11. A support column 2 is arranged at the bottom of the drone body 1. The bottom of the support column 2 is rotatably connected to a rotating rod 4 through a universal ball seat 3. The bottom of the rotating rod 4 is fixedly connected to a bottom plate 5. The outer surface of the bottom plate 5 is connected to a rope winding column 7 through a first steel rope 6. A motor 8 is arranged on the top of the drone body 1. The output end of the motor 8 is connected to the rope winding column 7.

[0033] The protection mechanism 10 includes a second steel rope 1001, one end of which is connected to a sponge sheet 1004, one side of the sponge sheet 1004 is fixedly connected to a spring sleeve rod 1005, one end of the spring sleeve rod 1005 is fixedly connected to a shell 1002, and a slide groove 1003 is provided on the inner wall of the shell 1002. The support column 2 connects the UAV body 1 and the base plate 5, providing a stable support structure, which ensures that the base plate 5 and the surveying equipment thereon can be stably fixed under the UAV and will not be affected by bumps during flight. The combination of the universal ball seat 3 and the rotating rod 4 enables the base plate 5 to rotate freely in multiple directions, which increases the adaptability and flexibility of the device on complex terrain.

[0034] See also Figure 1 , Figure 3 The second steel rope 1001 is fixedly connected to the first steel rope 6. Two first steel ropes 6 are provided. The two first steel ropes 6 are symmetrically arranged along the central axis of the UAV body 1. The second steel rope 1001 is fixedly connected to the first steel rope 6, which plays the role of connecting and transmitting tension.

The first steel rope 6 plays a key stretching and supporting role in the device. By setting two first steel ropes 6 and symmetrically arranging them along the central axis of the UAV body 1, the stability and balance of the bottom plate 5 during the unfolding and storage process are ensured.

[0035] See also Figure 3 There are two groups of spring rods 1005, each group of spring rods 1005 is provided with two. The spring rods 1005 are used to automatically pull back the sponge sheet 1004. During the operation of the remote sensing geological survey device, the sponge sheet 1004 is pulled to wipe the lens of the hyperspectral survey instrument 11.

A reflective coating is provided at the bottom of the bottom plate 5, and the reflective coating is located at the bottom of the bottom plate 5 to reduce the interference of light on the hyperspectral survey instrument 11. At the same time, the reflected light can disperse flying birds and prevent collisions. The through holes 13 are evenly and equidistantly arranged in a filling array on the bottom plate 5. The through holes reduce the weight of the bottom plate, which helps to improve the flight efficiency and endurance of the drone.

[0037] See also Figure 1 , Figure 4There are four rotating rods 4, which are evenly and equidistantly arranged in a rectangular array. A damping spring 12 is arranged inside the rotating rod 4.

[0040] The implementation principle of the utility model is as follows: first, before the UAV takes off, the protection mechanism 10 is in a retracted state, and the sponge sheet 1004 and the spring sleeve rod 1005 connected to the second steel rope 1001 are stored in the outer shell 1002. After take-off is completed, the motor 8 drives the rope column 7 to rotate, and controls the bottom plate 5 to rotate to both sides through the first steel rope 6. At the same time, the sponge sheet 1004 is pulled open to wipe the lens of the hyperspectral survey instrument 11. When the UAV lands on complex ground such as water, swamps, and mud, the structure of the bottom plate 5 and the rotating rod 4 enables the UAV to be stably supported to avoid sinking and being unable to be retrieved. The GPS signal generator 9 is connected to the external console through electrical signals, which is convenient for the operator to monitor the position in real time.
