Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of exploration equipment, especially a chute detection device. BACKGROUND

[0002] The chute refers to an important roadway structure in mine exploitation, which is mainly used for putting down ore from top to bottom by using the weight of ore, and in the chute, a chute detector is needed for detection, which can measure the mine goaf and the chute, especially plays an important role in underground mining safety, and can accurately measure the three-dimensional data of underground cavity to help guide underground operation and safety management.

[0003] For example, the patent literature with the publication number: "CN222068064U" discloses a chute detection device, which comprises a scanner, a scanner protection assembly and a rope assembly; the scanner protection assembly comprises a top plate and a frame, the top plate is arranged on the top of the frame, a protection area is formed in the frame, the projection of the protection area in the direction of the top plate completely falls on the top plate, the scanner is installed on the lower surface of the top plate and located in the protection area. By using the patent technical scheme, since the scanner is located in the protection area in the frame, the scanner will not directly contact or collide with the shaft wall, so that the scanner is protected. However, when the scanner moves in the chute, it needs to be pulled by manpower with the help of the rope, which increases the labor intensity. With the gradual maturity of the unmanned aerial vehicle technology, the unmanned aerial vehicle technology is gradually applied to the exploration field. When the depth of the chute is large and there are more curves inside the chute, the above detection method is no longer applicable. When the detector is mounted on the unmanned aerial vehicle and enters the chute for detection, since the light in the chute is insufficient, the control personnel outside the chute cannot observe the real-time flight state of the unmanned aerial vehicle, and the unmanned aerial vehicle cannot completely avoid collision with the shaft wall during flight, so that the scanner is still easy to collide with the shaft wall and be damaged.
