Description

Technical Field

[0001] The present invention relates to the technical field of geological exploration, and in particular to a geophysical exploration device for geological exploration. Background Art

[0002] Geological exploration is a survey and research activity that uses various means and methods to survey and detect geology, determine the appropriate bearing layer, determine the foundation type based on the bearing capacity of the bearing layer, and calculate the foundation parameters.

[0003] When using an ultrasonic CT detector for geological exploration, it is necessary to carry the instrument manually to the designated location for exploration. Therefore, exploration in rugged terrain and on the sides of mountains is difficult and risky. During exploration, the horizontality of the ultrasonic CT detector needs to be adjusted. The ground inclination of different terrains is different, so the explorers need to make continuous adjustments. Summary of the invention

[0004] The problem solved by the present invention is to provide a geophysical exploration device for geological exploration, which solves the problem that when conducting geological exploration with an ultrasonic CT detector, it is necessary to manually carry the instrument to a designated location for exploration, so exploration on steep terrain and the sides of mountains is difficult and risky. During exploration, the horizontality of the ultrasonic CT detector needs to be adjusted. The ground inclination of different terrains is different, so the exploration personnel need to make continuous adjustments.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A geophysical prospecting device for geological exploration comprises a mounting seat installed at the bottom of an unmanned aerial vehicle, the mounting seat being provided with an adjustment slot, a slide seat being slidably mounted in the adjustment slot, a rotating column being mounted at the bottom of the slide seat, the rotating column being rotatably mounted on the column seat, a turntable being mounted at the bottom end of the column seat, the bottom side of the turntable being connected to a fixing ring through a plurality of connecting arms arranged at equal angles, an adjusting disk being rotatably mounted on the fixing ring, an ultrasonic CT detector, an air pump and a spirit level being mounted on the adjusting disk, a probe of the ultrasonic CT detector passing through the center of the adjustment disk, a plurality of fixing seats being equiangularly mounted on the bottom side of the fixing ring, a rotating block being rotatably mounted in the fixing seat, the rotating block being connected to a pneumatic cylinder, and the pneumatic cylinder being connected to an air pump through a hose, an air pump being mounted at the telescopic end of the pneumatic cylinder, and an observation camera being mounted at the bottom of the fixing ring.

[0007] Preferably, a first motor is installed on the mounting seat, a threaded rod is installed on the output end of the first motor, and the threaded rod is threadedly connected to the sliding seat, and sliding rails slidably connected to the sliding seat are arranged on both sides of the adjusting groove.

[0008] Preferably, the rotating column and the column seat are connected by an inserted shaft, a wheel seat is installed on the bottom side of the sliding seat end, a second motor is installed on the side wall of the wheel seat, and a winding wheel is installed on the output end of the second motor located in the wheel seat, and a connecting rope is connected to the winding wheel.

[0009] Preferably, an adjusting shaft is installed on the turntable, a rotating drum is rotatably installed on the adjusting shaft, and the rotating drum is connected to the bottom end of the connecting rope.

[0010] Preferably, the fixing ring and the adjusting disk are connected via a bearing, an inner side of the fixing ring is provided with internal teeth, a third motor is mounted on the adjusting disk, a first rotating tooth is mounted on an output end of the third motor, and the first rotating tooth is meshed with the internal teeth.

[0011] Preferably, a plurality of translation grooves are provided at equal angles on the fixed ring, a plurality of translation rails parallel to the translation grooves are provided at equal angles on the fixed ring, a translation block is slidably mounted on the translation rail, and the plurality of translation blocks move synchronously.

[0012] Preferably, a plurality of arc grooves are provided at equal angles on the adjusting disk, and a guide column penetrating the translation grooves and the arc grooves is installed on the translation block.

[0013] Preferably, a mounting shaft is installed through the rotating block, the mounting shaft is connected to the fixed seat bearing, and a second rotating tooth is installed at the end of the mounting shaft, and a rack is installed on the translation block, and the rack is meshed with the second rotating tooth.

[0014] Preferably, the specific operating steps of the device are as follows:

[0015] Step 1: The device is driven to fly and move by the drone. When it is necessary to conduct longitudinal geological detection, the drone drives the device to move downward. When the device is close to the ground, the ground conditions are observed through the observation camera. The third motor drives the first rotating tooth to rotate, and cooperates with the meshing internal teeth to drive the adjustment disk to rotate. When the adjustment disk rotates, the arc groove on the adjustment disk acts on the guide column, driving the guide column to move along the translation groove. At this time, the translation block connected to the guide column moves along the translation rail, and the second rotating tooth is driven to rotate through the moving rack, thereby driving the rotating block and the pneumatic cylinder to rotate. The pneumatic cylinder rotates downward, and the pneumatic cylinder is driven to extend and retract through the air pump until the limit airbags at the telescopic end of the pneumatic cylinder are in contact with the ground, and the level meter remains horizontal. At this time, detection is performed through the ultrasonic CT detector and the probe;

[0016] Step 2: When conducting horizontal detection of rock geology, the pneumatic cylinder is in a folded storage state. The second motor drives the winding wheel to rotate and reel in the connecting rope. At this time, the rotating column rotates between the column seats, and then pulls the turntable upward 90° to maintain a vertical state. At the same time, the first motor drives the threaded rod to rotate, and then drives the slide to move in the adjustment slot to adjust the center of gravity of the entire device to prevent the drone from shaking and the device from tilting significantly during horizontal detection. Then, detection is carried out using an ultrasonic CT detector and probe.

[0017] The beneficial effects of the present invention are: combining the device with a drone, controlling the drone to move the entire device, facilitating geological exploration work in rugged terrain, improving the efficiency of geological exploration, and greatly reducing the danger of geological exploration;

[0018] The second motor drives the winding wheel to rotate to wind and unwind the connecting rope. At this time, the rotating column rotates between the column seats, thereby realizing the rotation of the turntable. When the turntable rotates to a horizontal state, the adjusting disk rotates to drive the guide column to move in the arc groove and the translation groove, driving the translation block to move along the translation rail, and driving the second rotating tooth to rotate through the moving rack, thereby driving the rotating block and the pneumatic cylinder to rotate. During flight, the pneumatic cylinder is in a stored state. During detection, the pneumatic cylinder rotates downward to an expanded state. The limit airbags at the telescopic ends of the pneumatic cylinder are in contact with the ground and the level is adjusted by the telescopic pneumatic cylinder. Therefore, the device is kept in a horizontal state during detection to complete longitudinal detection. When the turntable rotates to a vertical state, the slide seat moves in the adjusting slot to adjust the center of gravity of the entire device to avoid shaking of the drone and a large tilt of the device during lateral detection. Horizontal detection realizes detection of the sides of mountains and rivers. BRIEF DESCRIPTION OF THE DRAWINGS
