Description

Technical Field

[0001] The utility model relates to the technical field of land surveying and mapping, and in particular to an unmanned aerial vehicle surveying and mapping device based on land planning. Background Art

[0002] In the field of land planning and surveying, soil testing is often required. For some soft soil areas or soil layers with harsh environments, drones are generally used to take soil samples and then test the soil.

[0003] A Chinese utility model patent with publication number CN220418862U discloses a UAV surveying and mapping device based on land planning, including: a body and wings, two fixing plates are fixedly installed at the lower end of the body, a U-shaped plate is fixedly installed at the lower ends of the two fixing plates, an adjusting component is arranged inside the U-shaped plate, the adjusting component includes a first servo motor, a rotating shaft is fixedly installed at the output end of the first servo motor, an adjusting plate is fixedly installed on the outer surface of the rotating shaft, a drilling component is arranged at the lower end of the U-shaped plate, and a material taking component is arranged at the upper end of the adjusting component.

[0004] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: the soil in the sampling tube is easy to fall off during the rotation of the sampling tube, and the suction force of the pump can only absorb the soil in the sampling tube close to the pump, and the soil near the lower end is still easy to fall off, affecting the sampling effect. Utility Model Content

[0005] In order to solve the above problems, the utility model provides an unmanned aerial vehicle surveying and mapping device based on land planning.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a UAV surveying and mapping device based on land planning, including a UAV body, a driving motor is fixed on the lower surface of the UAV body, a sampling barrel is arranged at the end of the output shaft of the driving motor, the lower end of the sampling barrel is open, a spiral cutter is fixedly sleeved on the outer wall of the sampling barrel, an electric push rod is fixed on the lower surface of the UAV body, a mounting plate is fixed on the end of the output shaft of the electric push rod, a closing component for closing the opening of the sampling barrel is installed on the mounting plate, and the closing component includes a rotating motor fixed to the lower surface of the mounting plate, a connecting plate fixed to the end of the output shaft of the rotating motor, and a closing plate fixed to the side wall of the connecting plate.

[0007] By adopting the above technical solution, when soil sampling is required, the drone is brought close to the soil, and then the driving motor is started to drive the sampling tube to rotate, so that the spiral cutter drives the sampling tube to drill into the soil for sampling. When the sampling tube is drilled out of the soil after sampling, the mounting plate is moved downward by controlling the electric push rod, and then the connecting plate and the closing plate are rotated by the rotating motor, so that the closing plate closes the mouth of the sampling tube, thereby reducing the probability of soil falling after sampling, which is beneficial to improving the sampling effect.

[0008] Furthermore, the inner wall of the sampling tube is provided with spiral blades.

[0009] By adopting the above technical solution and setting the spiral blades, the soil stays on the spiral blades during the process of the sampling tube rotating and drilling into the soil, further reducing the probability of soil falling.

[0010] Furthermore, a rubber sheet is fixed on the upper surface of the closing plate.

[0011] By adopting the above technical solution, the rubber sheet is made of rubber material with good sealing performance, and the closing plate cooperates with the sampling tube and presses against the rubber sheet, thereby enhancing the sealing performance of the closing plate on the sampling tube.

[0012] Furthermore, a fixing block is fixed to the end of the output shaft of the driving motor, a fixing groove is opened at the bottom of the fixing block, and a fixing component for fixing the sampling tube is installed on the fixing block, and the fixing component includes a mounting block fixed to the upper end of the sampling tube and plugged into the fixing groove, a pin plugged into the fixing block and the mounting block at the same time, and a pull block fixed to the end of the pin away from the mounting block.

[0013] By adopting the above technical solution, the pin is plugged into the fixed block and the mounting block at the same time, so that the sampling cylinder is fixed on the fixed block. When the sampling cylinder needs to be removed, the staff only needs to remove the pin from the mounting block by pulling the block to remove the sampling cylinder, thereby facilitating maintenance and cleaning of the sampling cylinder.

[0014] Furthermore, the cross-sections of the mounting block and the fixing groove are both rectangular.

[0015] By adopting the above technical solution, the rectangular cross-section mounting block and the fixing groove prevent the mounting block from rotating in the fixing groove, which is beneficial for the driving motor to drive the sampling tube to rotate.

[0016] Furthermore, a mounting groove is formed on the side wall of the fixing block, a spring is arranged in the mounting groove, one end of the spring is fixed to the side wall of the pulling block, and the other end of the spring is fixed to the inner wall of the mounting groove.

[0017] By adopting the above technical solution, the pull block keeps the latch pin plugged into the mounting block under the elastic force of the spring, thereby reducing the probability of the latch pin falling off the mounting block and causing the sampling tube to fall off.

[0018] Furthermore, a yielding portion cooperating with the mounting block is provided on the lower surface of the latch.

[0019] By adopting the above technical solution, the installation block can squeeze the pin into the fixing block during the process of inserting the installation block into the fixing groove, eliminating the tedious operation of the staff to pull the pull block, and facilitating the installation of the sampling tube.

[0020] Furthermore, a protective cover for covering the rotating motor is fixed to the lower surface of the mounting plate, the output shaft of the rotating motor passes through the inner bottom wall of the protective cover and is rotatably connected, and a protective shell for covering the electric push rod and the driving motor is fixed to the lower surface of the drone body.

[0021] By adopting the above technical solution, the protective cover and the protective shell protect the rotating motor, the electric push rod and the drive motor, reducing the probability of damage to the rotating motor, the electric push rod and the drive motor under the action of external force.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. In the present application, when soil sampling is required, the drone is brought close to the soil, and then the driving motor is started to drive the sampling tube to rotate, so that the spiral cutter drives the sampling tube to drill into the soil for sampling. When the sampling tube is drilled out of the soil after sampling, the mounting plate is moved downward by controlling the electric push rod, and then the connecting plate and the closing plate are rotated by the rotating motor, so that the closing plate closes the mouth of the sampling tube, which reduces the probability of soil falling after sampling and is conducive to improving the sampling effect.

[0024] 2. In the present application, the setting of the spiral blades enables the soil to stay on the spiral blades when the sampling tube rotates and drills into the soil, further reducing the probability of soil falling;

[0025] 3. In the present application, the latch is plugged into both the fixed block and the mounting block, so that the sampling tube is fixed on the fixed block. When the sampling tube needs to be removed, the staff only needs to remove the latch from the mounting block by pulling the block, thereby removing the sampling tube, which is convenient for maintenance and cleaning of the sampling tube.

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0031] like Figure 1-3 As shown, an embodiment of the present application discloses a UAV surveying and mapping device based on land planning, including a UAV body 1, a driving motor 2, a sampling tube 3, a spiral knife 31, an electric push rod 4, a mounting plate 5 and a closing assembly 6.

[0032] The drone body 1 is a drone body 1 commonly used in the prior art and applicable to the present embodiment. The drive motor 2 is fixed to the lower surface of the drone body 1, and the output shaft of the drive motor 2 extends vertically downward. The sampling barrel 3 is a cylindrical structure, and the sampling barrel 3 is arranged at the end of the output shaft of the drive motor 2, and the lower end of the sampling barrel 3 is open. The spiral blade 31 is a spiral structure, and the spiral blade 31 is fixedly sleeved on the outer wall of the sampling barrel 3. The electric push rod 4 is fixed to the lower surface of the drone body 1, and the telescopic rod of the electric push rod 4 extends vertically downward. The mounting plate 5 is a rectangular plate-like structure, and the mounting plate 5 is fixed to the end of the telescopic rod of the electric push rod 4.

[0033] The closing assembly 6 is mounted on the mounting plate 5 and is used to close the opening of the sampling tube 3. The closing assembly 6 includes a rotating motor 61, a connecting plate 62 and a closing plate 63. The rotating motor 61 is fixed to the lower surface of the mounting plate 5, and the output shaft of the rotating motor 61 extends vertically downward. The connecting plate 62 is a rectangular plate-shaped structure, and the connecting plate 62 is fixed to the end of the output shaft of the rotating motor 61. The closing plate 63 is a circular plate-shaped structure, and the closing plate 63 is fixed to the side wall of the connecting plate 62.

[0034] When soil sampling is required, the drone is brought close to the soil, and the driving motor 2 is started to drive the sampling tube 3 to rotate, so that the spiral cutter 31 drives the sampling tube 3 to drill into the soil for sampling. When the sampling tube 3 is finished and drilled out of the soil, the mounting plate 5 is moved downward by controlling the electric push rod 4, and then the connecting plate 62 and the closing plate 63 are rotated by the rotating motor 61, so that the closing plate 63 closes the mouth of the sampling tube 3, thereby reducing the probability of soil falling after sampling, which is beneficial to improving the sampling effect.

[0035] In order to further reduce the probability of soil falling, the inner wall of the sampling tube 3 is provided with a spiral blade 32. The setting of the spiral blade 32 allows the soil to stay on the spiral blade 32 during the process of the sampling tube 3 rotating and drilling into the soil, thereby further reducing the probability of soil falling.

[0036] In order to enhance the sealing performance of the closing plate 63 to the sampling tube 3, a rubber sheet 7 is fixed to the upper surface of the closing plate 63. The rubber sheet 7 is made of rubber material with good sealing properties. The closing plate 63 cooperates with the sampling tube 3 and presses against the rubber sheet 7, thereby enhancing the sealing performance of the closing plate 63 to the sampling tube 3.

[0037] In order to facilitate the maintenance and cleaning of the sampling barrel 3, a fixing block 8 is fixed to the end of the output shaft of the driving motor 2, and a fixing groove 81 is provided at the bottom of the fixing block 8. A fixing assembly 9 is installed on the fixing block 8 for fixing the sampling barrel 3. The fixing assembly 9 includes a mounting block 91, a latch 92 and a pull block 93. The mounting block 91 is fixed to the upper end of the sampling barrel 3, and the mounting block 91 is plugged into the fixing groove 81. The latch 92 is a horizontally arranged rectangular rod-shaped structure, and the latch 92 is plugged into the fixing block 8 and the mounting block 91 at the same time. The pull block 93 is a round block-shaped structure, and the pull block 93 is fixed to the end of the latch 92 away from the mounting block 91. The latch 92 is plugged into the fixing block 8 and the mounting block 91 at the same time, so that the sampling barrel 3 is fixed on the fixing block 8. When the sampling barrel 3 needs to be disassembled, the staff only needs to remove the latch 92 from the mounting block 91 through the pull block 93, thereby disassembling the sampling barrel 3, so as to facilitate the maintenance and cleaning of the sampling barrel 3.

[0038] In order to prevent the mounting block 91 from rotating in the fixing groove 81, the cross-sections of the mounting block 91 and the fixing groove 81 are both rectangular. The mounting block 91 and the fixing groove 81 with rectangular cross-sections prevent the mounting block 91 from rotating in the fixing groove 81, which is beneficial for the driving motor 2 to drive the sampling tube 3 to rotate.

[0039] In order to reduce the probability of the pin 92 falling off the mounting block 91, a mounting groove 82 is opened on the side wall of the fixing block 8, and a spring 10 is arranged in the mounting groove 82. One end of the spring 10 is fixed to the side wall of the pull block 93, and the other end of the spring 10 is fixed to the inner wall of the mounting groove 82. Under the action of the elastic force of the spring 10, the pull block 93 keeps the pin 92 plugged into the mounting block 91, thereby reducing the probability of the pin 92 falling off the mounting block 91 and causing the sampling tube 3 to fall off.

[0040] In order to facilitate the installation of the sampling tube 3, a yielding portion 921 is provided on the lower surface of the pin 92 to cooperate with the mounting block 91, so that the mounting block 91 can squeeze the pin 92 into the fixing block 8 during the insertion of the fixing groove 81, eliminating the tedious operation of the staff to pull the pull block 93, thereby facilitating the installation of the sampling tube 3.

[0041] In order to protect the rotating motor 61, the electric push rod 4 and the driving motor 2, a protective cover 11 for covering the rotating motor 61 is fixed to the lower surface of the mounting plate 5, and the output shaft of the rotating motor 61 passes through the inner bottom wall of the protective cover 11 and is rotatably connected. A protective shell 12 for covering the electric push rod 4 and the driving motor 2 is fixed to the lower surface of the drone body 1. The protective cover 11 and the protective shell 12 protect the rotating motor 61, the electric push rod 4 and the driving motor 2, thereby reducing the probability of damage to the rotating motor 61, the electric push rod 4 and the driving motor 2 under the action of external force.

[0042] The use principle of a drone surveying and mapping device based on land planning in this embodiment is: when soil sampling is required, the drone is used to approach the soil, and then the driving motor 2 is started to drive the sampling tube 3 to rotate, so that the spiral knife 31 drives the sampling tube 3 to drill into the soil for sampling. When the sampling tube 3 is completed and drilled out of the soil, the mounting plate 5 is moved downward by controlling the electric push rod 4, and then the connecting plate 62 and the closing plate 63 are rotated by the rotating motor 61, so that the closing plate 63 closes the tube mouth of the sampling tube 3, thereby reducing the probability of soil falling after sampling, which is beneficial to improving the sampling effect.

[0043] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
