Description

Technical Field

[0001] The invention relates to the technical field of data collection unmanned aerial vehicles, and in particular to a reservoir basin three-dimensional geographic information data collection unmanned aerial vehicle. Background Art

[0002] Three-dimensional geographic information data of reservoir basins is an important basis for reservoir management, planning and decision-making support. These data are obtained through modern technical means such as drones, remote sensing technology, GIS (geographic information system), etc., providing detailed and accurate information for the all-round management of reservoir basins.

[0003] Drone technology plays an indispensable role in many fields due to its high precision and high efficiency. Among them, the drone point cloud acquisition system uses sensors such as lidar or depth cameras to perform three-dimensional scanning and data collection on the ground or buildings, generate three-dimensional models or digital elevation models (DEM), and provide strong support for the collection of three-dimensional geographic information data in reservoir basins.

[0004] The laser radar on the drone acquires the distance information of the target object by emitting laser beams and measuring their reflection time. During the flight, the laser radar continuously collects the three-dimensional coordinate data of the ground or buildings to form a point cloud data set. At the same time, the depth camera calculates the distance between the object and the camera through the principle of stereo vision. Similar to the laser radar, the depth camera also collects three-dimensional coordinate data during the flight of the drone.

[0005] At present, the actual use of drones for collecting three-dimensional geographic information data in reservoir basins still has the following shortcomings. If a drone malfunctions and crashes while collecting data in a reservoir basin, most of the current drones will fall directly onto the water surface and then sink to the bottom of the water. This may cause important data such as geographic information and environmental monitoring data stored in the drone to be lost or damaged due to the crash. At the same time, due to the large and deep reservoir, it may be difficult to quickly find and salvage it, which increases the difficulty and cost of salvaging the drone. Summary of the invention

[0020] Beneficial effects of the present invention:

[0021] 1.

If the drone cannot float on the water surface after falling into water, the difficulty of salvaging and recovering it will be greatly increased. After airbags 1 and 2 are deployed, the drone can float on the water surface, which is convenient for searching and salvaging, reducing the difficulty and time cost of rescue. In addition, the drone may be equipped with important aerial survey equipment or data. Once falling into water, it may cause data loss, affecting the construction period and agency reports.

In the present invention, when the drone malfunctions and falls into the water, airbags 1 and 2 are deployed to make the drone float on the water surface, and at the same time, the battery pack on the sinking bottom plate is driven to sink, so that the battery pack moves from the inside of the drone to the bottom of the drone, so that the center of gravity of the drone floating on the water surface is lowered, and the lower center of gravity can increase the stability of the drone, so that it can maintain a stable floating state even in waters with strong winds and waves, thereby improving the survivability and safety of the drone in emergency situations.

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] Example 1

[0044] Reference Figure 1-7 , which is the first embodiment of the present invention, provides a reservoir basin three-dimensional geographic information data collection drone, the reservoir basin three-dimensional geographic information data collection drone comprises a drone operation top warehouse 1 and a mounting base plate 2 installed at the bottom of the drone operation top warehouse 1, support columns 3 installed on both sides of the mounting base plate 2, a support cross pipe 4 fixedly connected to the end of the support column 3 away from the mounting base plate 2, three groups of rubber rings 5 ​​fixedly sleeved on the surface of the support cross pipe 4, which can be used for buffering when the drone lands and contacts the ground, a floating component 6 arranged on the support column 3 and the support cross pipe 4 to prevent the drone from falling and sinking to the bottom, and a center of gravity lowering component 7 arranged on the drone operation top warehouse 1 and the mounting base plate 2 to lower the center of gravity of the drone;

[0045] The floating component 6 includes a floating component 61 arranged on the supporting cross tube 4 for floating the drone, a fixed installation bin 62 fixedly installed in the inner cavity of the supporting column 3, a CO2 gas cylinder 63 connected to one end of the fixed installation bin 62, and the bottle mouth of the CO2 gas cylinder 63 extends to the inner cavity of the fixed installation bin 62, a gas release component 64 arranged in the inner cavity of the supporting column 3 for puncturing the CO2 gas cylinder 63, and a conveying component 65 arranged in the inner cavity of the supporting cross tube 4 for transmitting gas to the inner cavity of the CO2 gas cylinder 63. The floating component 61 includes an installation bin 611 fixedly installed on both sides of the two ends of the surface of the supporting cross tube 4, a bin cover 612 hinged on the top of one end of the installation bin 611, an air bag 613 installed at one end of the inner cavity of the installation bin 611, and an air intake pipe 614 connected to the air bag 613, and one end of the air intake pipe 614 extends to the inner cavity of the supporting cross tube 4.

[0046] The floating assembly 61 also includes a blocking plate 615 fixedly installed on both sides of the inner cavity of the supporting cross tube 4, an air bag 616 installed on one side of the blocking plate 615, an air intake pipe 617 connected to the air bag 616, and one end of the air intake pipe 617 passes through the blocking plate 615 and is sleeved on a blocking cover 618 on the two end surfaces of the supporting cross tube 4.

[0047] The gas release assembly 64 includes a salt storage bin 641 installed at one end of the fixed installation bin 62 away from the CO2 gas cylinder 63, a connecting pipe 642 connected to the bottom end of the support column 3, and one end of the connecting pipe 642 extends to the inner cavity of the supporting cross tube 4, an air guide pipe 643 slidably sleeved on the connecting pipe 642 located at one end of the inner cavity of the support column 3, and one end of the air guide pipe 643 slides through the salt storage bin 641 and extends to the inner cavity of the fixed installation bin 62, a limiting disk 644 fixedly sleeved on the surface of the air guide pipe 643, and the limiting disk 644 is located in the inner cavity of the salt storage bin 641, where one side of the limiting disk 644 in the inner cavity of the salt storage bin 641 is filled with salt blocks for blocking the limiting disk 644, A limiting disk 2 646 is fixedly mounted between the connecting main pipe 642 on the surface of the air guide pipe 643 and the salt storage bin 641, a spring 647 is mounted between the connecting main pipe 642 on the surface of the air guide pipe 643 and the limiting disk 2 646, a plurality of connecting ports 1 645 are arranged on the surface of the salt storage bin 641 to facilitate water to enter the inner cavity of the salt storage bin 641 to dissolve the salt blocks inside, a plurality of connecting ports 2 648 are arranged on the bottom of the surface of the support column 3, and the arrangement of the connecting ports 2 648 at the bottom of the surface of the support column 3 allows water to enter the inner cavity of the support column 3 through the connecting ports 2 648 when the drone falls into the water, and a piercing member 649 is arranged on one end of the air guide pipe 643 located in the inner cavity of the fixed installation bin 62.

[0048] The piercing member 649 includes an inverted cone piercing head 6491 fixedly mounted on the air guide tube 643 at one end of the inner cavity of the fixed mounting bin 62, so as to facilitate piercing the bottle mouth of the CO2 gas cylinder 63, and an air inlet hole 6492 opened on the surface of the inverted cone piercing head 6491, so as to facilitate the transfer of the inner cavity gas of the CO2 gas cylinder 63 into the air guide tube 643 through the air inlet hole 6492.

[0049] The conveying assembly 65 includes a one-way valve 651 connected to the connecting main pipe 642 at one end of the inner cavity of the supporting cross tube 4, a three-way pipe fitting 652 connected to one end of the one-way valve 651, and the one-way valve 651 is used to allow gas to enter the three-way pipe fitting 652 only from the connecting main pipe 642, an air supply pipe 653 connected to the other two ends of the three-way pipe fitting 652, an air inlet pipe 614 at one end of the inner cavity of the supporting cross tube 4 and connected to the air supply pipe 653, and an air inlet pipe 617 at one end away from the airbag 2 616 and connected to the air supply pipe 653.

[0050] During use, when the drone crashes due to a malfunction while collecting data in the reservoir basin, the drone has no power due to the malfunction, and gravity causes the drone to fall. When the drone falls close to the water surface, the supporting transverse pipe 4 will first contact the water surface of the reservoir, and then the bottom end of the supporting column 3 will contact the water surface, and then the water will enter the inner cavity of the supporting column 3 through the second connecting port 648. As the drone continues to fall, the water source in the inner cavity of the supporting column 3 continues to rise, slowly submerging the connecting main pipe 642;

[0051] When the water floods the salt storage bin 641, the water will enter the inner cavity of the salt storage bin 641 through the connecting port 1 645 and melt the salt block inside. When the salt block is melted, the restriction disk 1 644 will be unblocked. At this time, the rebound force of the spring 1 647 can push the restriction disk 2 646 to move, and at the same time, the restriction disk 1 644 moves in the inner cavity of the salt storage bin 641, and finally the air guide tube 643 drives the inverted cone piercing head 6491 to pierce the bottle mouth of the CO2 gas cylinder 63 and extend to the inner cavity of the CO2 gas cylinder 63, and then the gas in the CO2 gas cylinder 63 enters the air guide tube 64 through the air inlet hole 6492. The gas in the inner cavity is then transferred to the connecting main pipe 642, and then enters the three-way pipe 652 through the one-way valve 1 651 and is transferred to the two sets of gas delivery pipes 653 respectively, and then the gas is delivered to the airbag 1 613 and the airbag 2 616 through the air inlet pipe 1 614 and the air inlet pipe 2 617. When the airbag 1 613 is filled with gas, it begins to expand and pushes open the compartment cover 612, so that the airbag 1 613 extends to the outside of the installation compartment 611. At the same time, the airbag 2 616 begins to expand after being filled with gas, and pushes open the blocking cover 618, and then the airbag 2 616 also expands and extends to the outside of the supporting cross pipe 4.

[0052] Thereby, the two groups of supporting transverse tubes 4 on the UAV form buoyancy, and then the UAV can float on the water surface of the reservoir, thereby preventing the UAV from being soaked in water and sinking to the bottom, and facilitating subsequent salvage operations.

[0059] The anti-fall component 79 includes a threaded groove 793 opened at the bottom end of the surface of the sliding rod 73, a receiving base plate 791 arranged below the mounting base plate 2, and four groups of sliding rods 73 sliding through the receiving base plate 791, a nut 794 threadedly connected to the bottom end of the surface of the sliding rod 73 and adapted to the threaded groove 793, and a plurality of groups of buffer rubber strips 792 fixedly installed on the top of the receiving base plate 791, so as to facilitate buffering and shock absorption of the descending sinking base plate 75 to avoid damage to the battery pack 71 on the sinking base plate 75.

[0060] During use, when the drone falls onto the water surface, water will enter the inner cavity of the salt storage bin 641 through the connecting port 1 645 and melt the salt blocks inside, so that the airbag 1 613 and the airbag 2 616 on the two sets of supporting cross tubes 4 on the drone will unfold to form buoyancy, and then the drone can float on the water surface of the reservoir. When the gas in the inner cavity of the CO2 gas cylinder 63 is transferred to the connecting main pipe 642 through the air guide pipe 643, a part of the gas is inflated to the airbag 1 613 and the airbag 2 616 through the one-way valve 1 651, and the other part of the gas is transported to the gas transfer pipe 772 through the one-way valve 2 771, and then transferred to the U-shaped tube 773 and sprayed out from the two ports of the U-shaped tube 773, and then the blocking plug can be pushed. When the rod 765 moves out of the U-shaped tube 773, the two sets of connecting cross plates 762 will move closer to each other on the surface of the connecting cross rod 761 and compress the spring 2 764. When the blocking rod 765 moves out of the U-shaped tube 773, the fixing between the sinking bottom plate 75 and the mounting bottom plate 2 is cancelled. Then, the sleeve block 74 will slide down on the surface of the sliding rod 73 by gravity and drive the battery pack 71 on the sinking bottom plate 75 to descend. When the bottom of the sinking bottom plate 75 contacts the buffer rubber strip 792 on the top of the receiving bottom plate 791, the battery pack 71 can be moved from the mounting bottom plate 2 to the bottom of the mounting bottom plate 2, thereby lowering the center of gravity of the drone, making the drone float more stably on the water.

[0061] When the sinking bottom plate 75 descends to the top of the receiving bottom plate 791, spring three 788 can pull the movable sleeve block 786 to slide on the surface of the positioning bottom rod 785, and at the same time, the fixed plug rod 787 moves and is inserted into the socket 783 on the sliding rod 73. Then the sinking bottom plate 75 can be fixed, further improving the stability of the sinking bottom plate 75 on the receiving bottom plate 791.
