Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle remote sensing, in particular to a portable geophysical exploration collection and processing unmanned aerial vehicle airborne remote sensing geophysical exploration instrument. Background Art

[0002] Geophysical exploration, collection and processing by drone-mounted remote sensing geophysical instruments refers to the use of remote sensing geophysical instruments to detect the radiation and reflection characteristics of electromagnetic waves of objects. Remote sensing measurements can conduct ground observations over a large area in a relatively short period of time and obtain valuable remote sensing data from them.

[0003] After searching, a portable geophysical exploration collection and processing drone-mounted remote sensing geophysical instrument with announcement number CN215361879U is found. When the tilt angle of the remote sensing geophysical instrument body needs to be adjusted during use, the wireless remote control switch is controlled by an external remote control. The wireless remote control switch controls the brake motor to open. The output shaft of the brake motor drives the right shaft to rotate, and the right shaft drives the remote sensing geophysical instrument body to rotate. When the remote sensing geophysical instrument body rotates to a suitable angle position, the brake motor is closed and the adjustment is completed, making it convenient to adjust the tilt angle of the remote sensing geophysical instrument body according to use needs and increase the observation range.

[0004] However, the rotation of the remote sensing geophysical detector body driven by the rotating shaft can only achieve rotation and swing in one direction. When it is necessary to tilt and swing in other directions, the drone needs to be controlled to rotate in a hovering state. Controlling the rotation of the drone will inevitably cause the remote sensing geophysical detector body to shake, which may affect the detection effect of the remote sensing geophysical detector body.

[0005] The purpose of the utility model is to provide a portable geophysical exploration collection and processing drone airborne remote sensing geophysical exploration instrument to solve the problems of low efficiency and insufficient extraction of the existing gardenia meal processing technology proposed in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A portable geophysical exploration collection and processing drone airborne remote sensing geophysical instrument, comprising a drone body, a remote sensing geophysical instrument and a rotating shaft for installing the remote sensing geophysical instrument, the lower surface of the drone body is rotatably connected to a rotating seat for rotatably installing the rotating shaft, one end of the rotating shaft passes through the rotating seat and extends outwardly to be fixedly connected to a bevel gear block, and is located on the lower surface of the rotating seat and rotatably connected to an inner bevel gear ring meshing with the bevel gear block, the side edge of the inner bevel gear ring extends outwardly and is fixedly connected to a bottom bevel gear ring, the side edge of the rotating seat is in the shape of a bevel gear ring, an extension plate is fixedly connected to the bottom of the drone body, a lifting rod is penetrated through the extension plate, and the rod surface of the lifting rod is fixedly connected to two hard rubber blocks for respectively engaging with the side edge of the rotating seat and the bottom bevel gear ring.

[0008] By adopting the above technical solution, the lifting rod can be raised and lowered so that when the hard rubber block on the upper surface of the lifting rod engages with the side of the rotating seat, the lifting rod can be rotated to realize the rotation of the rotating seat, thereby realizing the rotation of the remote sensing geophysical instrument on the rotating seat. When the lifting rod is lowered to the bottom hard rubber block and engages with the bottom bevel gear ring, the bottom bevel gear ring can be driven to rotate by rotating the lifting rod, thereby realizing the rotation of the inner bevel gear ring, and the bevel gear block can drive the rotating shaft to rotate, thereby realizing the swing of the remote sensing geophysical instrument.

[0011] The utility model is further configured that the hard rubber blocks at the upper and lower positions on the lifting rod are used alternately and respectively engage with the cone gear ring-shaped part on the side of the rotating seat and the bottom cone gear ring.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0030] like Figure 1-6 As shown, the utility model provides a technical solution: a portable geophysical exploration collection and processing drone airborne remote sensing geophysical instrument, comprising a drone body 1, a remote sensing geophysical instrument 5 and a rotating shaft 7 for installing the remote sensing geophysical instrument 5, the lower surface of the drone body 1 is rotatably connected with a rotating seat 9 for rotatably installing the rotating shaft 7, one end of the rotating shaft 7 passes through the rotating seat 9 and extends outwardly and is fixedly connected with a bevel gear block 8, and an inner bevel gear ring 6 meshing with the bevel gear block 8 is rotatably connected to the lower surface of the rotating seat 9, the side edge of the inner bevel gear ring 6 extends outwardly and is fixedly connected with a bottom bevel gear ring 2, the bottom bevel gear ring 2 is used to rotate to drive the inner bevel gear ring 6 to rotate, and then the meshing bevel gear block 8 drives the rotating shaft 7 to rotate, that is, The remote sensing geophysical instrument 5 fixed on the rotating shaft 7 can be swung. The side of the rotating seat 9 is set in a bevel gear ring shape. The bottom of the UAV body 1 is fixedly connected to an extension plate 4, and a lifting rod 11 is arranged through the extension plate 4. The rod surface of the lifting rod 11 is fixedly connected to two hard rubber blocks 12 which are respectively used to engage with the side and bottom bevel gear rings 2 of the rotating seat 9. The lifting rod 11 is used to lift and lower. When the lifting rod 11 rises to the position above its surface, the hard rubber block 12 is embedded and engaged with the tooth surface of the bevel gear ring on the side of the rotating seat 9. The lifting rod 11 is used to rotate and drive the hard rubber block 12 to rotate, thereby realizing that the rotating seat 9 in the engaged state drives the remote sensing geophysical instrument 5 to rotate, and the remote sensing geophysical instrument 5 can be swung in different directions.

[0031] In addition, the lifting rod 11 is also rotatably connected to a connecting block 14 that penetrates the side of the extension plate 4, and the side of the extension plate 4 is fixedly connected to an electric push rod 13 for driving the connecting block 14 to rise and fall. The contact portion of the extension plate 4 and the connecting block 14 is hollowed out, and the hollowed-out portion is slidably connected to the connecting block 14, so that the connecting block 14 can be ensured not to rotate, but to rise and fall only under the telescopic action of the electric push rod 13, thereby driving the lifting rod 11 to rise and fall, and the lifting rod 11 is rotatably connected to the connecting block 14, so that the rotation of the lifting rod 11 is not affected.

[0032] Further explanation of the hard rubber block 12: the hard rubber blocks 12 in the upper and lower positions on the lifting rod 11 are used alternately, and respectively engage with the bevel gear ring portion on the side of the rotating seat 9 and the bottom bevel gear ring 2. The contact portions of the hard rubber block 12 with the rotating seat 9 and the bottom bevel gear ring 2 are all inclined, so it can ensure full contact and embedded engagement with the tooth surface when in contact, which is convenient for realizing linkage.

[0033] In order to lock the bottom bevel gear ring 2 or the rotating seat 9: the top position of the lifting rod 11 is rotatably connected to a lifting seat 17 sleeved on the longitudinal part of the extension plate 4, a guide plate 16 is fixedly connected to the position near the lifting seat 17 on the drone body 1, and racks 10 are installed on the lifting seat 17 and the guide plate 16, a spur gear 15 meshing with the opposite tooth surfaces of the two racks 10 is rotatably connected to the extension plate 4, and the side of the rack 10 on the guide plate 16 is fixedly connected with a friction pad 3 for alternate use and against the bevel gear ring part on the side of the rotating seat 9 and the bottom bevel gear ring 2, one of the racks 10 is fixed on the lifting rod 11. On the seat 17, the tooth back of another rack 10 is embedded and inserted in the side of the guide plate 16. As shown in the figure, when the lifting rod 11 descends, it will drive the rotatably connected lifting seat 17 to descend under the auxiliary action of the extension plate 4, and will not affect the rotation of the lifting rod 11. When the lifting seat 17 descends with the descent of the lifting rod 11, the rack 10 on the surface of the lifting seat 17 will synchronously descend. Under the meshing connection of the spur gear 15, the other rack 10 is realized. Rise along the surface of the guide plate 16, the friction pad 3 fixed on the surface of the rack 10 on the guide plate 16 can be achieved. Rise to the side contact with the rotating seat 9 and damping cooperation.

[0034] In order to realize the rotation of the lifting rod 11 , the lifting rod 11 is driven by a motor, and the motor driving the lifting rod 11 is fixed on the lifting seat 17 .

[0035] Working principle: as shown in the figure, the hard rubber block 12 above the surface of the lifting rod 11 is engaged with the tooth surface of the bevel gear ring part on the side of the rotating seat 9. Therefore, the lifting rod 11 is driven by a motor to rotate, which drives the hard rubber block 12 to rotate, so that the rotating seat 9 in the engaged state can drive the remote sensing geophysical instrument 5 to rotate, so that the remote sensing geophysical instrument 5 can swing in different directions. When driving the remote sensing geophysical instrument 5 to swing, it is only necessary to extend the electric push rod 13 to realize that the connecting block 14 drives the lifting rod 11 to descend to the position below its surface so that the hard rubber block 12 is engaged with the tooth surface of the bottom bevel gear ring 2. The lifting rod 11 can be driven by a motor to rotate, which drives the hard rubber block 12 to rotate, so that the bottom bevel gear ring 2 in the engaged state drives the inner bevel gear ring 6 to rotate, and then the meshing bevel gear block 8 drives the rotating shaft 7 to rotate, so that the remote sensing geophysical instrument 5 fixed on the rotating shaft 7 can swing.

[0036] In addition, the motor and electric push rod 13 involved in the utility model are motors and electric push rod devices of any corresponding models that can be purchased on the market. Therefore, as known products, their internal structures, wiring diagrams and working principles are all known technologies, and therefore they are not described in detail.
