Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example: Figure 1-5As shown, the utility model provides a drone for environmental detection, including a fuselage 1, a connector 11 and a sensor 12 are fixedly installed at the bottom end of the fuselage 1, a first protective box 13 and a second protective box 14 are movably provided below the fuselage 1, a double-headed screw 15 with opposite threads at both ends is provided on one side of the first protective box 13 and the second protective box 14, a fixing block 16 is fixedly installed on one side of the first protective box 13 and the second protective box 14 close to the double-headed screw 15, the double-headed screw 15 threads penetrate the two fixing blocks 16, a fixing frame 17 is fixedly installed on the inner wall of the first protective box 13 and the second protective box 14, a movable plate 18 is movably provided on the opposite side of the inner wall of the fixed frame 17, and a silicone pad 19 and an airbag 191 are fixedly installed on both sides of the movable plate 18.

[0019] A stabilizing plate 2 is fixedly installed at the bottom of the second protective box 14, a slot 21 is provided at the top of the stabilizing plate 2, an empty slot 22 is provided at the bottom of the first protective box 13, a clamping plate 23 is clamped at the bottom end of the first protective box 13, the clamping plate 23 passes through the empty slot 22, and the clamping plate 23 is distributed in an L-shaped state, and evenly distributed stabilizing holes 24 are provided at the bottom end of the first protective box 13, a spring 25 is fixedly installed inside the stabilizing hole 24, and the other end of the spring 25 is fixedly connected to the clamping plate 23.

[0020] A symmetrically distributed support plate 3 is fixedly installed on one side of the bottom end of the fuselage 1 close to the double-headed screw 15. The double-headed screw 15 rotates and passes through the two support plates 3. By setting the support plate 3, the double-headed screw 15 can be supported so that it can rotate smoothly, thereby driving the first protective box 13 and the second protective box 14 to move towards each other.

[0021] A motor 4 is coaxially fixedly mounted on one end of the double-headed screw 15, and the sensor 12 and the motor 4 are electrically connected. By providing the motor 4, it is convenient to drive the double-headed screw 15 to rotate, thereby realizing protection of the digital remote sensing equipment.

[0022] Limiting blocks 5 are fixedly installed on the top of the first protective box 13 and the second protective box 14, and symmetrically distributed limiting grooves 51 are provided at the bottom of the fuselage 1. The limiting blocks 5 are movably clamped in the limiting grooves 51. By setting the limiting blocks 5 and the limiting grooves 51, the first protective box 13 and the second protective box 14 are prevented from being offset during the movement, so that they can better fit the digital remote sensing equipment.

[0023] Blocks 6 are fixedly installed on both sides of the movable plate 18 away from the silicone pad 19, and through grooves 61 are opened on both sides of the fixed frame 17 close to the block 6. The block 6 is movably clamped in the through groove 61. By setting the block 6 and the through groove 61, the movable plate 18 can be supported and its stability is improved.

[0024] The bottom of the fuselage 1 is fixedly installed with symmetrically distributed mounting blocks 7, the bottom end of the mounting blocks 7 is fixedly installed with fixing rods 71, and a support rod 72 is movably inserted inside the fixing rod 71. By setting the mounting blocks 7, the fixing rods 71 ​​and the support rods 72, the fuselage 1 can be supported.

[0025] The outer side of the fixing rod 71 is provided with evenly distributed first fixing holes 8, and the top of the support rod 72 is provided with a second fixing hole 81. By setting the first fixing hole 8 and the second fixing hole 81, the support rod 72 is pulled out of the fixing rod 71 by one end, and the second fixing hole 81 is aligned with one of the first fixing holes 8 and fixed by fixing screws, so that the height of the fuselage 1 can be adjusted to facilitate adaptation to different environments.

[0026] The number of the first fixing holes 8 is three, so that the fuselage 1 can be adjusted to different heights.

[0027] The side of the stabilizing plate 2 close to the empty slot 22 is distributed in a trapezoidal state, and the top of the clamping plate 23 is distributed in a trapezoidal state, so that the stabilizing plate 2 can better push the clamping plate 23 downward when it moves.

[0028] Working principle: In actual use, the digital remote sensing device is installed in the connecting piece 11. When the speed of the drone drops abnormally, the sensor 12 sends a command to the motor 4 and drives the motor 4 to work, so that the output end of the motor 4 drives the double-headed screw 15 to rotate. At this time, the two fixing blocks 16 threadedly sleeved on the outside of the double-headed screw 15 move toward each other, and the two fixing blocks 16 respectively drive the first protection box 13 and the second protection box 14 to move toward each other until the silicone pad 19 and the digital remote sensing device fit together. When the drone falls, the digital remote sensing device is cushioned by the silicone pad 19. At the same time, the airbag 191 can absorb part of the impact force and reduce the damage to the digital remote sensing equipment; when the first protective box 13 and the second protective box 14 are close to each other, the stabilizing plate 2 enters the empty slot 22 and pushes the card plate 23 downward. At this time, the spring 25 is stretched. When the card slot 21 comes to the top of the card plate 23, the spring 25 is reset and drives the card plate 23 to move upward until it is stuck in the card slot 21, thereby fixing the first protective box 13 and the second protective box 14, thereby providing secondary protection and reducing the probability of the first protective box 13 and the second protective box 14 falling off from the digital remote sensing equipment.

[0029] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
