[0083] The information collecting component 32 is coaxially arranged with the drill body 27;

[0084] Each pressure sensing plate 33 is connected to the information collection unit 32 via a corresponding first telescopic rod 341. The pressure sensing plate 33 can measure the compressibility, internal friction, and shear strength of the rock and soil, which are used to reflect the mechanical properties of the rock and soil, when subjected to pressure. Specifically, in the present application, a total of four pressure sensing plates 33 are provided, each of which is connected to the information collection unit 32 via two first telescopic rods 34. The telescopic direction of the first telescopic rod 341 is consistent with the radial direction of the drill bit body 27.

[0087] Example 2:

[0088] On the basis of embodiment 1, an electromagnet 35 is fixedly provided on the inner side of the impact drill bit 29;

[0089] When the electromagnet 35 is powered on, the information collecting component 32 is fixedly connected to the impact drill bit 29 through the electromagnet 35 ; when the electromagnet 35 is powered off, the information collecting component 32 is separated from the impact drill bit 29 .

[0090] Preferably, Figure 2 As shown, the launch chamber 7 is provided with a winding mechanism 10 capable of pulling and recovering the information collection mechanism 28;

[0091] The wire coiling mechanism 10 includes a wire coiling motor 23, a wire coiling shaft, and a traction wire 24 wound on the wire coiling shaft; the wire coiling motor 23 is fixedly mounted on the inner wall of the launch chamber 7, the wire coiling shaft 23 is connected to the output shaft of the wire coiling motor 23, and the free end of the traction wire 24 is connected to the information collection unit 32;

[0092] When the winding motor 23 is powered on, the winding shaft is controlled to rotate to reclaim the traction line 24. When the winding motor is powered off, the winding shaft rotates freely.

[0093] Preferably, the outer cover of the wire coiling mechanism 10 is provided with a wire coiling box 25 fixedly arranged in the launching chamber 7, and the wire coiling box 25 is provided with a wire outlet 26 for the traction wire 24 to pass through.

[0094] Preferably, the bottom of the percussion drill 30 is annular in shape, and a through hole 36 for the traction line 24 to pass through is provided on the bottom of the percussion drill 30, wherein the structure of the bottom of the percussion drill 30 is as follows: Figure 4 As shown;

[0095] After the pressure sensing plate 33 , the pore water pressure gauge 38 , and the water content sensor 39 are reset inwardly, the information collection mechanism 28 can pass through the inner hole of the bearing drill bottom 30 .

[0096] Preferably, the ejection plate 21 is provided with a wire scavenging groove 22 for providing a sliding channel for the traction line 24; the wire scavenging groove 22 has a smooth surface and provides a sliding channel for the traction line to prevent the line from being stuck; wherein the structure of the ejection plate 21 is as follows Figure 3 As shown;

[0097] Therefore, the traction line 24 extends out through the outlet 26 on the wire coil box 25, passes through the wire slit 22 on the ejection plate 21, the wire hole 36 on the impact drill bottom 30 and is connected to the information collection part 32.

[0098] The specific implementation of the drone-mounted drilling and surveying device for high and steep slope survey in Example 2 is as follows:

[0099] Before the drilling and testing device of the present application is flown, the motor 11 is energized to control the movement of the rack 15 to compress the launch spring 20 and store energy; then the test drill bit 4 is placed into the launch slot 9, and the line winding motor 23 is energized to control the line winding shaft to rotate to tighten the traction line 24, so as to ensure that the test drill bit 4 will not fall out of the launch slot 9 when the drilling and testing device is in flight.

[0100] The drilling and testing device of the present application flies to the vicinity of the position to be tested, and the camera mechanism 2 takes a picture of the position to be tested and finally determines the test position, and aligns the impact drill bit 29 with the test position; then the winding motor 23 is powered off to make the traction line 24 in a freely pull-out state, and then the motor 11 is powered off to make the gear 17 rotate freely without applying resistance to the rack 15. At this time, under the elastic force of the launch spring 20, the ejection plate 21 drives the ejection rod 12 to move to the right and collide with the test drill bit 4, thereby launching the test drill bit 4 to the test position to achieve drilling; wherein the test drill bit 4 will drive the traction line 24 to extend when it is launched.

[0101] Control the first telescopic rod 341 to extend outwards, such as Figure 7-8As shown, the pressure sensing plate 33 is passed through the through hole 31 on the drill bit body 27 to squeeze the surrounding rock and soil to obtain rock and soil compressibility, internal friction, and shear strength data used to reflect the mechanical properties of the rock and soil. After the pressure sensing plate 33 completes the measurement, the first telescopic rod 341 is controlled to retract inward, while the second telescopic rod 342 is controlled to extend outward, so that the pore water pressure gauge 38 and the water content sensor 39 extend outward to push out the corresponding dust plugs 37. Figure 9 As shown, the pore water pressure and the water content of the rock and soil are then measured; after the pore water pressure gauge 38 and the water content sensor 39 are measured, the first telescopic rod 341 and the second telescopic rod 342 are controlled to be retracted to their positions, so that the adjacent pressure sensing plates 33 are connected to form a protective shell for the information collection unit 32, as shown in FIG. Figure 10-11 As shown, the information collecting component 32 is protected and the volume of the information collecting mechanism 28 is reduced.

[0102] Then the electromagnet 35 is powered off to separate the information collection mechanism 28 from the impact drill bit 29; then the wire winding motor 23 is powered on to control the wire winding shaft to rotate to tighten the winding traction wire 24, and the information collection mechanism 28 is removed from the inner hole of the impact drill bottom 30 under the drive of the traction wire 24 to achieve the recovery of important testing instruments.

[0103] In this application, the camera structure 2, the motor 11, the winding motor 23, the pressure sensor plate 33, the first telescopic rod 341, the second telescopic rod 342, the electromagnet 35, the pore water pressure gauge 38, and the water content sensor 39 are all connected to the main controller in the drone body 1. The main controller is connected to the remote control mechanism through wireless signals, and can realize the control of a series of instructions such as flight, aiming, launching, testing, and recovery; the drone body 1 and the remote control mechanism matched therewith can be realized by using existing technology, and its specific structure will not be repeated here.

[0104] Although the above describes the specific embodiments of the present invention in conjunction with the accompanying drawings, it is not a limitation of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without any creative work are still within the scope of protection of the present invention.
