Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) measurement technology, and in particular to a UAV measurement head adjustment device. Background Technology

[0002] In surveying operations, the measuring heads (such as lidar and multispectral cameras) on unmanned aerial vehicles (UAVs) often need to continuously oscillate within a certain angle range to expand the effective coverage of a single flight or to continuously scan the target area, thereby improving operational efficiency and data acquisition density. Existing adjustment devices typically achieve this oscillation through motor-driven gear transmission.

[0003] However, the current adjustment device still has some shortcomings in use. For example, during reciprocating reversal, the transmission components are easily subjected to inertial impact, which causes impact stress on the gear meshing surface and aggravates wear. When the wear at the gear meshing clearance increases with long-term use of the equipment, it will cause the measuring head to wobble when it reaches the preset left and right limit positions, affecting the accuracy of the measurement data. Secondly, during the use of the adjustment device, the lubricating oil at the gear meshing gradually reduces its effectiveness over a certain period of time, leading to increased wear. In the existing device, lubricating oil is usually replenished periodically by manual disassembly, which is inconvenient for the device to adaptively lubricate according to the degree of wear during use.

[0004] Therefore, this application provides a drone measurement head adjustment device to meet the requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a drone measuring head adjustment device to solve the problems of existing devices, which are prone to inertial impact during reciprocating reversal, resulting in impact stress on the gear meshing surface, aggravated wear, and inconvenience in adaptive lubrication according to the degree of wear during use.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A drone measuring head adjustment device includes: a mounting base fixed to the bottom of the drone; a cavity inside the mounting base; a connector rotatably connected to the bottom of the cavity; a gear ring fixed to the upper outer wall of the connector inside the cavity; a mounting plate fixed to the inner wall of the cavity; a first gear rotatably connected to the bottom of the mounting plate via a motor, the first gear meshing with the gear ring; an adjustment frame fixed to the bottom of the connector; a measuring head body rotatably connected to the end of the adjustment frame via a motor; an electric telescopic rod fixed to the center of the mounting plate; a lifting plate rotatably connected to the movable end of the electric telescopic rod; two piston boxes fixed to the bottom of the lifting plate; a plug slidably connected to one side of each piston box; a stop plate fixed to one end of each plug; a spring connecting the stop plate and the piston box; a drive rod abutting one side of each stop plate; each drive rod fixed to the top surface of the connector; and a limit hole opened at the top of the piston box corresponding to the position of the drive rod. A first positioning component is provided on the outer side of the lifting plate, and a second positioning component is provided on the outer side of the shaft of the first gear.

[0008] Optionally, the piston box has an arc-shaped structure, the center of the arc of the piston box corresponds to the center of the joint, and the bottom of the piston box located on the side of the abutment plate has an open structure.

[0009] Optionally, the first positioning component includes a plurality of first brackets fixedly connected to the bottom of the mounting plate, each of the first brackets having an elastic telescopic rod fixedly connected to the side near the lifting plate, and each of the elastic telescopic rods having a first wedge fixedly connected to its movable end.

[0010] Optionally, a plurality of the first brackets are arranged in a circular array on the outside of the lifting plate, the side wall of the lifting plate is a sloping structure, and the sloping surface of the first wedge block corresponds to the sloping structure of the lifting plate.

[0011] Optionally, the second positioning component includes a collar fixedly connected to the bottom of the mounting plate. A second gear is rotatably connected to the outer wall of the collar. Two locking blocks are symmetrically slidably connected to the outer wall of the collar via a slide rod. A rack is fixedly connected to one side of each locking block. The two racks are staggered and mesh with the second gear.

[0012] Optionally, a second wedge is fixedly connected to the side wall of the locking block near the lifting plate. The inclined surface of the second wedge corresponds to the inclined surface structure of the lifting plate. A hanging rod is slidably sleeved on the outer wall of the second wedge. The top end of the hanging rod is fixed to the mounting plate. The hanging rod and the locking block are connected by a spring.

[0013] Optionally, each piston box has a first one-way tube and a second one-way tube fixedly connected through the rodless chamber sidewall, and a drip head is fixedly connected to the rod sidewall. The drip head is located at the meshing point of the first gear and the gear ring, and the first one-way tube is connected to the drip head through a pipe.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] In the above scheme, by setting up a piston box, plug body, stop plate, and spring, the inertial impact when the measuring head body swings to the maximum swing position is reduced. When the motor stops, the lifting plate rises, and in conjunction with the first positioning component and the second positioning component, the lifting plate and the rotating shaft of the first gear are positioned, so that the measuring head body is accurately positioned. At the same time, it avoids large-scale shaking of the joint due to wear gap. The rotation tendency of the joint causes the drive rod to squeeze the stop plate and compress the spring, converting inertial kinetic energy into elastic potential energy, avoiding hard collision between the gear ring and the first gear, reducing the wear of transmission components, and improving the service life and positioning stability of the device.

[0016] In the above scheme, by setting up a piston box, a first one-way pipe, a second one-way pipe, and a drip head, on-demand lubrication of the gear transmission parts is achieved. During the buffering process, the squeezing force of the drive rod on the abutment pushes the plug to compress the lubricating oil in the piston box. The oil is pumped to the drip head through the first one-way pipe and drips onto the meshing point of the first gear and the gear ring. The greater the inertia, the stronger the squeezing force, and the more lubricating oil is pumped, thus achieving adaptive matching of lubrication supply. Attached Figure Description

Detailed Implementation

[0029] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0030] like Figures 1 to 10As shown, an embodiment of the present invention provides a drone measuring head adjustment device, including: a mounting base 1, which is fixed to the bottom of the drone. A cavity 2 is formed inside the mounting base 1, and a connector 3 is rotatably connected through the bottom of the cavity 2. The connector 3 is rotatable in the horizontal direction. A gear ring 4 is fixed to the upper outer wall of the connector 3 inside the cavity 2. A mounting plate 5 is fixed to the inner wall of the cavity 2. A first gear 6 is rotatably connected to the bottom of the mounting plate 5 via a motor. The first gear 6 meshes with the gear ring 4. When the motor drives the first gear 6 to rotate, the meshing of the first gear 6 with the gear ring 4... The motor is used to adjust the horizontal rotation angle of connector 3. The forward and reverse rotation of the motor allows connector 3 to reciprocate horizontally. An adjusting frame 7 is fixed to the bottom of connector 3. The end of the adjusting frame 7 is connected to the measuring head body 8 via a motor. The adjusting frame 7 and the measuring head body 8 rotate synchronously with connector 3. The pitch angle of the measuring head body 8 is adjusted by the rotation of the motor at the end of the adjusting frame 7. An electric telescopic rod 9 is fixed through the center of the mounting plate 5. A lifting plate 10 is rotatably connected to the movable end of the electric telescopic rod 9. The bottom of the lifting plate 10 is fixed... Two piston boxes 11 are symmetrically installed about one diameter of the lifting plate 10. A plug 12 is slidably connected to one side of each piston box 11. The two plugs 12 are arranged in opposite directions around the circumference of the lifting plate 10. A stop plate 13 is fixedly connected to one end of each plug 12. The stop plate 13 is connected to the piston box 11 by a spring. A drive rod 14 abuts against one side of each stop plate 13. Each drive rod 14 is fixed to the top surface of the connector 3. A limit hole 15 is provided at the top of the piston box 11 corresponding to the position of the drive rod 14. The lifting plate 10 lowers... When lowered, the drive rod 14 fixed at the top of the connector 3 is inserted into the limiting hole 15 of the piston box 11. The rotation of the connector 3 will drive the lifting plate 10 and the piston box 11 to rotate synchronously. A first positioning component 16 is provided on the outside of the lifting plate 10, and a second positioning component 17 is provided on the outside of the shaft of the first gear 6. When the electric telescopic rod 9 drives the lifting plate 10 to rise, it slides against the first positioning component 16 and the second positioning component 17, so that the first positioning component 16 restricts the inertial rotation of the lifting plate 10, and at the same time, the second positioning component 17 positions the shaft of the first gear 6.

[0031] The piston box 11 has an arc-shaped structure, and the center of the arc of the piston box 11 corresponds to the center of the joint 3. The bottom of the piston box 11 located on one side of the abutment plate 13 has an open structure.

[0032] Specifically, the top of the mounting base 1 is connected to the UAV via a threaded sleeve. When the measuring head body 8 needs to perform reciprocating swing measurement, the forward and reverse rotation of the motor drives the first gear 6 to rotate reciprocally. Furthermore, the meshing of the first gear 6 with the gear ring 4 drives the connector 3, the adjusting frame 7, and the measuring head body 8 to rotate synchronously, thus realizing the reciprocating swing measurement of the measuring head body 8. During the rotation of the connector 3, the electric telescopic rod 9 drives the lifting plate 10 to descend, so that the drive rod 14 fixed at the top of the connector 3 is inserted into the limiting hole 15 of the piston box 11. The rotation of the connector 3 will drive the lifting plate 10 and the piston box 11 to rotate synchronously. When the measuring head body 8 reaches the maximum swing position required for measurement, the motor driving the first gear 6 stops, and at the same time, the electric telescopic rod 9 drives the lifting plate 10 to rise, so that the drive rod 14 fixed at the top of the connector 3 disengages from the limiting hole 15 of the piston box 11, but still abuts against the abutment plate 13. At this time, the first positioning component 16 positions the lifting plate 10, and the second positioning component 17 positions the rotating shaft of the first gear 6, restricting its rotation. The connector 3 continues to rotate under inertia, causing the drive rod 14 to press against the abutment plate 13. Through the spring action between the abutment plate 13 and the piston box 11, the hard collision is reduced. Then, the motor driving the first gear 6 rotates in the opposite direction. This cycle reduces the wear of the gear ring 4 and the first gear 6 during the reciprocating swing measurement process of the measuring head body 8.

[0033] The first positioning component 16 includes a plurality of first brackets 161 fixedly connected to the bottom of the mounting plate 5. Each first bracket 161 is fixedly connected to an elastic telescopic rod 162 on the side near the lifting plate 10. Each elastic telescopic rod 162 is fixedly connected to a first wedge 163 at its movable end.

[0034] Multiple first supports 161 are arranged in a circular array on the outside of the lifting plate 10. The side wall of the lifting plate 10 has a sloping structure, and the sloping surface of the first wedge 163 corresponds to the sloping structure of the lifting plate 10.

[0035] Specifically, during the upward movement of the lifting plate 10, the inclined structure on its outer side contacts and presses against the inclined surfaces of the multiple first wedges 163 distributed in a circular array, causing each first wedge 163 to overcome the elastic force of the corresponding elastic telescopic rod 162 and generate a contraction displacement in the direction of the first support 161. When the electric telescopic rod 9 drives the lifting plate 10 to reach the preset end point of the upward stroke, the inclined surface of the lifting plate 10 abuts tightly against the inclined surface of the first wedge 163, and the inertial rotation of the lifting plate 10 is restricted by the multiple first wedges 163 arranged in a circumferential manner.

[0036] The second positioning component 17 includes a collar 171 fixedly connected to the bottom of the mounting plate 5. A second gear 172 is rotatably connected to the outer wall of the collar 171. Two locking blocks 173 are symmetrically slidably connected to the outer wall of the collar 171 via a slide rod. A rack 174 is fixedly connected to one side of each locking block 173. The two racks 174 are staggered and mesh with the second gear 172.

[0037] A second wedge 175 is fixedly connected to the side wall of the locking block 173 near the lifting plate 10. The inclined surface of the second wedge 175 corresponds to the inclined surface structure of the lifting plate 10. A hanging rod 176 is slidably sleeved on the outer wall of the second wedge 175. The top end of the hanging rod 176 is fixed to the mounting plate 5. The hanging rod 176 and the locking block 173 are connected by a spring.

[0038] Specifically, during the process of the electric telescopic rod 9 driving the lifting plate 10 to rise, the inclined surface of the lifting plate 10 gradually contacts and compresses the inclined surface of the second wedge block 175. Since the second wedge block 175 is fixed on the locking block 173 near the lifting plate 10, this compression pushes the locking block 173 to overcome the tension of the spring on the boom 176 and slide along the slide bar on the outer wall of the collar 171 away from the lifting plate 10. The movement of the locking block 173 drives the rack 174 fixed on one side to move synchronously. Since the two racks 174 are staggered and mesh with the second gear 172, when one rack 174 moves, it drives the second gear 172 to rotate. The rotation of the second gear 172 drives the other rack 174 meshing with it to move in the opposite direction, thereby pulling the locking block 173 on the other side to slide synchronously towards the shaft of the first gear 6. When the lifting plate 10 rises to the preset abutment position between its inclined surface and the inclined surface of the second wedge block 175, the two locking blocks 173 clamp the shaft of the first gear 6 from both sides, thus positioning the shaft of the first gear 6 and preventing it from micro-movement due to inertial rotation after the motor stops or under the action of external force. When the motor reverses, the electric telescopic rod 9 drives the lifting plate 10 to descend, causing its inclined surface to disengage from the inclined surface of the second wedge block 175. Under the restoring pull of the spring on the suspension rod 176, the locking blocks 173 that have been squeezed outward, together with the second wedge block 175, are pulled back to their initial positions.

[0039] Each piston box 11 has a first one-way tube 18 and a second one-way tube 19 fixedly connected through the rodless chamber sidewall. The sidewall of the rod 176 is fixedly connected to a drip head 20, which is located at the meshing point of the first gear 6 and the gear ring 4. The first one-way tube 18 is connected to the drip head 20 through a pipe, and the second one-way tube 19 is connected to an external lubricating oil tank.

[0040] Specifically, when the connector 3 tends to rotate due to inertia, the drive rod 14 fixed at its top will compress the abutment 13 inside the piston box 11, causing the abutment 13 to move the plug 12 into the rodless chamber of the piston box 11, compressing the pre-stored lubricating oil in the chamber. The pressurized lubricating oil opens the one-way valve in the first one-way pipe 18 and is pumped through the pipeline to the drip head 20 fixed to the side wall of the hanger 176. The outlet of the drip head 20 is located above the meshing point of the first gear 6 and the gear ring 4, whereby the lubricating oil drips down and lubricates the meshing tooth surfaces. During this process, the greater the inertia of the connector 3, the greater the squeezing force of the drive rod 14 on the abutment 13 and the greater the displacement of the plug 12, thereby increasing the amount of lubricating oil pumped out accordingly, achieving an adaptive match between lubrication supply and the magnitude of inertia. When the squeezing pressure is eliminated, the plug body 12 returns to its original position under the action of the spring. A negative pressure is generated in the rodless chamber of the piston box 11, and oil is replenished from the outside through the second one-way pipe 19. Thus, during the buffering process of each swing reversal, the transmission parts are automatically lubricated, which effectively reduces the wear at the first gear 6 and makes the swing of the measuring head body 8 stable and the positioning accurate.

[0041] The working principle of the technical solution provided by this invention is as follows:

[0042] During operation, the adjustment device is connected to the UAV via the threaded sleeve on the top of the mounting base 1, and the measuring head body 8 works in conjunction with the UAV to perform measurement operations. When the measuring head body 8 needs to swing horizontally, the motor on the mounting plate 5 is activated to drive the first gear 6 to rotate in both directions. The first gear 6 meshes with the gear ring 4 fixed on the connector 3, causing the connector 3 to rotate reciprocally in the horizontal plane, which in turn drives the measuring head body 8 to swing synchronously through the adjustment frame 7. At the same time, the electric telescopic rod 9 drives the lifting plate 10 to descend, so that the drive rod 14 fixed on the top of the connector 3 is inserted into the limiting hole 15 of the piston box 11, thereby forming a rigid connection between the lifting plate 10 and the piston box 11 and the connector 3, driving the measuring head to move accurately to the measurement position. When the measuring head body 8 reaches the maximum swing amplitude, the motor stops, and the electric telescopic rod 9 synchronously drives the lifting plate 10 to rise. During this process, the outer inclined surface of the lifting plate 10 is pressed against the inclined surface of the first wedge block 163 and finally tightly abuts against it. Through the circumferential constraint of multiple first wedge blocks 163, the rotation of the lifting plate 10 is restricted. As the lifting plate 10 rises, its inclined surface presses against the second wedge 175, pushing the connected locking block 173 to move. Through the transmission of the rack 174 and the second gear 172, the two locking blocks 173 move closer to each other, jointly clamping the rotating shaft of the first gear 6 for positioning. At this time, the joint 3 continues to rotate due to inertia, pressing the abutment plate 13 through the drive rod 14, forcing the plug 12 to compress the spring in the piston box 11, converting the inertial kinetic energy into the elastic potential energy of the spring, and preventing the gear ring 4 from having a hard impact with the first gear 6.

[0043] When the drive rod 14 presses against the abutment plate 13, it drives the plug body 12 to compress the lubricating oil in the rodless chamber of the piston box 11. The oil pressure opens the one-way valve of the first one-way pipe 18, allowing the lubricating oil to be transported through the pipeline to the drip head 20 fixed to the hanger rod 176. The outlet of the drip head 20 is located above the meshing point of the first gear 6 and the gear ring 4, and the lubricating oil drips precisely onto the gear meshing surface. During this process, the greater the inertia of the joint 3, the stronger the pressure of the drive rod 14 on the abutment plate 13, the greater the displacement of the plug body 12, and the corresponding increase in the amount of lubricating oil pumped out, thereby achieving an adaptive match between the lubrication supply and the intensity of motion inertia. After the buffering is completed, the plug body 12 returns to its original position under the action of the spring, and a negative pressure is generated in the piston box 11, which replenishes the oil from the outside through the second one-way pipe 19. When the motor drives the first gear 6 in the reverse direction, the electric telescopic rod 9 drives the lifting plate 10 to descend, causing its inclined surface to disengage from the compression of the first wedge block 163 and the second wedge block 175. Under the action of the springs at the elastic telescopic rod 162 of the first wedge 163 and the second wedge 175, all components reset, releasing the rotational restriction on the lifting plate 10 and the clamping of the first gear 6 shaft. Subsequently, the lifting plate 10 continues to descend until the drive rod 14 re-inserts into the limiting hole 15.
