Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV identification device for detecting joints and cracks in rock masses. Background Technology

[0002] Slope rock mass surveying is a crucial task in geotechnical engineering, engineering geology, hydropower, transportation, and mining. Its core purpose is to determine the stability of slopes and provide a scientific basis for design, construction, and long-term safe operation.

[0003] Within the rock mass of a slope, there are areas such as thickets, cracks, and steep cliffs. When using drones to survey and identify the rock mass of a slope, the drones cannot fly directly into these areas, thus creating survey blind spots. If they are forced to fly into these areas, the drones may collide and be damaged, requiring further surveying by staff. This not only reduces the efficiency of the slope rock mass survey but also increases the safety risks for the staff. Utility Model Content

[0004] The purpose of this invention is to provide a drone identification device for detecting joints and cracks in rock masses, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drone identification device for surveying rock mass joints and cracks, comprising a drone body and a survey camera 1 fixedly installed at one end of the bottom of the drone body. A mounting box is fixedly installed at the end of the bottom of the drone body away from the survey camera 1. A winding mechanism is provided inside the mounting box. A survey camera 2 is provided below the winding mechanism. Both ends of the mounting box are rotatably mounted with baffles. A spring 1 is fixedly installed on the side of the two baffles that are far apart from each other. The ends of the two springs that are far apart from each other are fixedly connected to the mounting box. A transmission mechanism is provided inside the mounting box.

[0006] Preferably, the winding mechanism includes a winding motor and a winding reel. The winding motor is fixedly installed inside the mounting box. The output shaft end of the winding motor is fixedly connected to the winding reel. A winding rope is wound around the outside of the winding reel. The end of the winding rope is fixedly connected to the second survey camera.

[0007] Preferably, a guide wheel is fixedly installed inside the mounting box, and the winding rope passes through the surface of the guide wheel.

[0008] Preferably, a counterweight ball is fixedly installed at the end of the winding rope, and the counterweight ball is positioned above the second survey camera.

[0009] Preferably, the transmission mechanism includes four guide rods, all of which are slidably sleeved inside the mounting box. A base plate is fixedly installed at the bottom of the four guide rods. A spring is sleeved on the outside of each of the four guide rods. A through hole is opened in the middle of the base plate, through which the winding rope passes. The diameter of the through hole is smaller than the diameter of the counterweight ball. Two symmetrically arranged connecting ropes are fixedly installed at one end of the top of the base plate, and the ends of the two connecting ropes are respectively fixedly connected to their corresponding baffle plates.

[0010] Preferably, multiple evenly distributed guide wheels are symmetrically fixedly installed at both ends inside the mounting box, and the two connecting ropes pass through the surface of their respective guide wheels.

[0011] Preferably, two symmetrically arranged limiting strips are fixedly installed on one side of the inner wall of the mounting box, and the two limiting strips cooperate with the two baffles respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up a second survey camera and using a rewind mechanism to control the height of the second survey camera, surveys can be conducted on areas such as bushes, cracks, and steep cliffs. This avoids blind spots, improves the efficiency of surveying slope rock masses, and reduces the safety risks for workers. Even if the second survey camera is damaged by a collision, the cost of equipment damage can be reduced compared to the cost of the drone itself flying directly into bushes, cracks, steep cliffs, etc.

[0013] 2. By setting two shielding plates, when the second survey camera is not in use, the two shielding plates will cover and protect the bottom opening of the mounting box, preventing external impurities from entering the mounting box and damaging the second survey camera when it is not used for a long time.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides a technical solution: such as Figure 1 - Figure 5 The device shown is a drone identification device for detecting joints and cracks in rock mass. It includes a drone body 1 and a survey camera 2 fixedly installed at one end of the bottom of the drone body 1. A mounting box 3 is fixedly installed at the end of the bottom of the drone body 1 away from the survey camera 2. A winding mechanism is provided inside the mounting box 3. A survey camera 4 is provided below the winding mechanism. Both ends of the mounting box 3 are rotatably installed with a baffle plate 5. A spring 6 is fixedly installed on the side of the two baffle plates 5 that are far apart from each other. The ends of the two springs 6 that are far apart from each other are fixedly connected to the mounting box 3. A transmission mechanism is provided inside the mounting box 3.

[0018] The winding mechanism includes a winding motor 7 and a winding reel 8. The winding motor 7 is fixedly installed inside the mounting box 3. The output shaft end of the winding motor 7 is fixedly connected to the winding reel 8. A winding rope 9 is wound around the outside of the winding reel 8. The end of the winding rope 9 is fixedly connected to the second survey camera 4.

[0019] Inside the mounting box 3, a guide wheel 10 is fixedly installed, and the winding rope 9 passes through the surface of the guide wheel 10.

[0020] A counterweight ball 12 is fixedly installed at the end of the winding rope 9, and the counterweight ball 12 is positioned above the second survey camera 4.

[0021] The transmission mechanism includes four guide rods 13, all of which are slidably sleeved inside the mounting box 3. A base plate 14 is fixedly installed at the bottom of the four guide rods 13. Springs 15 are sleeved on the outside of the four guide rods 13. A through hole 16 is opened in the middle of the base plate 14, through which the winding rope 9 passes. The diameter of the through hole 16 is smaller than the diameter of the counterweight ball 12. Two symmetrically arranged connecting ropes 17 are fixedly installed at one end of the top of the base plate 14. The ends of the two connecting ropes 17 are fixedly connected to their respective corresponding baffle plates 5.

[0022] Multiple evenly distributed guide wheels 18 are symmetrically fixed at both ends inside the mounting box 3, and two connecting ropes 17 pass through the surface of their respective guide wheels 18.

[0023] Two symmetrically arranged limiting strips 11 are fixedly installed on one side of the inner wall of the mounting box 3. The two limiting strips 11 cooperate with the two baffles 5 respectively.

[0024] Working principle: During use, the operator controls the drone body 1 to fly. In easily surveyable areas, the operator uses the survey camera 2 to conduct surveys and identifications. When the survey camera 2 identifies areas such as bushes, cracks, and steep cliffs, the operator starts the winding motor 7, which drives the winding reel 8 to rotate and release the winding rope 9. The survey camera 4 and the counterweight ball 12 move downwards under the action of gravity. At this time, the base plate 14 and multiple guide rods 13 move downwards under the action of multiple springs 15. During the downward movement of the base plate 14, it generates tension on the two connecting ropes 17. The bottom ends of the two connecting ropes 17 pull on the two shielding plates 5 respectively. The two shielding plates 5 rotate, thereby allowing the survey camera 4 to move downwards to the outside of the mounting box 3. While the two shielding plates 5 are moving, they squeeze the two springs 6 respectively. It should be noted that the elastic force of the multiple springs 15 is greater than the elastic force of the two springs 6. After releasing the winding rope 9 to the appropriate length, turn off the winding motor 7. Then, the survey camera 2 4 can be used to survey areas such as bushes, cracks, and steep cliffs. The survey camera 2 4 can extend into the rock joints and cracks for surveying and identification, avoiding blind spots, improving the surveying efficiency of slope rock mass, and reducing the safety risks for workers. Even if the survey camera 2 4 is damaged by collision, it can reduce the cost of equipment damage compared to the drone body 1 flying directly into bushes, cracks, steep cliffs, etc. After the survey is completed, the winding motor 7 reverses to wind up the winding rope 9, causing the counterweight ball 12 and the survey camera 4 to be drawn into the mounting box 3. When the counterweight ball 12 contacts the base plate 14, as the counterweight ball 12 continues to move upward, it pushes the base plate 14 and multiple guide rods 13 to move upward. Multiple springs 15 are compressed by force. At this time, the two baffle plates 5 are flipped under the action of two springs 6 until they contact the two limit strips 11 respectively. At this time, the two baffle plates 5 cover and protect the bottom opening of the mounting box 3 to prevent external impurities from entering the mounting box 3 and damaging the survey camera 4 when it is not used for a long time.
