Technical Field

[0001] This application relates to the technical field of unmanned aerial vehicles, and more specifically, to an unmanned aerial vehicle for watershed water resources investigation. Background Art

[0002] Protecting the water resources environment of the watershed is particularly important for water body monitoring. Currently, water body monitoring mainly relies on manual detection, buoy detection, and satellite remote sensing. Traditional manual monitoring methods have a long cycle, high cost, poor mobility, low efficiency, low accuracy, and also require a large amount of manpower and material resources; satellite remote sensing images have a long acquisition cycle, low resolution, are easily affected by weather, and have serious delays.

[0003] In related technologies, for an unmanned aerial vehicle, the unmanned aerial vehicle is used to map the water surface in the watershed to obtain mapping data. Then the unmanned aerial vehicle falls into the water for water navigation. The unmanned aerial vehicle floats or is provided with a floating airbag for floating, and then underwater mapping operations are carried out. When the unmanned aerial vehicle floats, the whole unmanned aerial vehicle needs to be waterproof and sealed. If there is leakage, it will directly affect the internal circuit of the unmanned aerial vehicle. When floating through a floating airbag, the floating airbag is also easily damaged and leaks air.

Detailed implementation manners

[0039] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0040] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0041] The river basin water resource survey UAV according to an embodiment of the present application will be described below with reference to the drawings.

[0042] As shown Figures 1 - 14 in the figure, the unmanned aerial vehicle for basin water resource investigation according to the embodiment of the present application includes: an unmanned aerial vehicle component 100 and a hull component 200. The unmanned aerial vehicle component 100 is used for aerial mapping, and the hull component 200 is used for underwater mapping.

[0043] As shown Figure 2 and Figure 3 in the figure, the hull component 200 includes a first hull 210, a second hull 220, a support frame 230, and a first telescopic driving member 240. The first hull 210 includes a first hull plate 211, and a card slot 212 is formed on one side of the first hull plate 211. The second hull 220 includes a second hull plate 221 and a card strip 222. The card strip 222 is fixedly connected to one side of the second hull plate 221. Among them, the card strip 222 and the second hull plate 221 are of an integral structure. A sealing strip 223 is arranged on the lower side of the card strip 222. The card strip 222 presses the sealing strip 223 into the card slot 212 to seal the pressing part between the second hull plate 221 and the first hull plate 211 through the sealing strip 223, reducing the situation of water leakage. Both the support frame 230 and the first telescopic driving member 240 are provided in two. The upper ends of the two support frames 230 are respectively fixedly connected to both ends of the lower side of the unmanned aerial vehicle component 100, and the lower ends of the two support frames 230 are respectively hinged to the inner walls of the first hull plate 211 and the second hull plate 221. One ends of the two first telescopic driving members 240 are hinged to the lower side of the unmanned aerial vehicle component 100, and the other ends of the two first telescopic driving members 240 are respectively hinged to the inner walls of the first hull plate 211 and the second hull plate 221. The sealing strip 223 is arranged as a rubber strip, which is convenient for sealing. When the unmanned aerial vehicle needs to conduct underwater mapping, control the unmanned aerial vehicle component 100 to approach the water surface, open one of the first telescopic driving members 240, and the first telescopic driving member 240 drives the first hull plate 211 to flip around the lower end of the support frame 230 until the first hull plate 211 is in a horizontal position. Then open the other first telescopic driving member 240, and the first telescopic driving member 240 drives the second hull plate 221 to flip around the lower end of the support frame 230. The first telescopic driving member 240 pushes the card strip 222 on the second hull plate 221 into the card slot 212 until the sealing strip 223 is pressed tightly against the card slot 212, and then control the unmanned aerial vehicle component 100 to make the first hull plate 211 and the second hull plate 221 float on the water surface. If water leakage occurs, the water first enters the first hull plate 211 and the second hull plate 221, and the water does not directly enter the unmanned aerial vehicle component 100. At this time, the unmanned aerial vehicle component 100 can be controlled to fly up, retract the first hull plate 211 and the second hull plate 221, deploy the first hull plate 211 and the second hull plate 221 again, make the card strip 222 press into the card slot 212 again, and try whether it is sealed again. If the water leakage problem is solved, the operation can continue. If the problem is not solved, it can be controlled to fly back for repair. The first hull plate 211 and the second hull plate 221 are stronger than the floating airbag and are not easily damaged.

Preferably, the first mounting plates 232 are respectively fixedly connected to both ends of the lower side of the drone assembly 100 by bolts. The first support plate 231 is fixed through the first mounting plate 232, which is convenient for installation. A first hinge seat 233 is fixedly connected to the lower end of the first support plate 231. When specifically arranged, the first hinge seat 233 and the first support plate 231 are of an integral structure. Two second hinge seats 234 are provided on the inner walls of both the first ship plate 211 and the second ship plate 221. Specifically, the second hinge seats 234 are integrally fixed to the inner walls of the first ship plate 211 and the second ship plate 221. The first hinge seat 233 is hinged between the two second hinge seats 234.

[0045] As Figure 5 shown, the first telescopic driving member 240 includes a first telescopic rod 241, two first double-ear plates 242, a first single-ear plate 243 and a second single-ear plate 244. The two first double-ear plates 242 are respectively fixedly connected to both ends of the first telescopic rod 241. The first single-ear plate 243 and the second single-ear plate 244 are respectively hinged to the two first double-ear plates 242. The first single-ear plate 243 is fixedly connected to the lower side of the drone assembly 100. The second single-ear plate 244 is fixedly connected to the inner walls of the first ship plate 211 and the second ship plate 221. Among them, the second single-ear plate 244 is integrally fixedly connected to the inner walls of the first ship plate 211 and the second ship plate 221. When the first telescopic rod 241 retracts, the first telescopic rod 241 drives the second single-ear plate 244, and the first double-ear plate 242 rotates around the second single-ear plate 244, and the second single-ear plate 244 drives the first ship plate 211 and the second ship plate 221 to flip.

[0046] As Figure 6As shown, leg members 250 are fixedly connected to the upper sides of the first deck plate 211 and the second deck plate 221. There are four leg members 250, which are symmetrically arranged on the upper sides of the first deck plate 211 and the second deck plate 221. The leg member 250 includes a support base 251 and a second telescopic rod 252. The support base 251 is fixedly connected to the inside of the first deck plate 211 and the second deck plate 221. The second telescopic rod 252 is fixedly connected to the support base 251. Preferably, the second telescopic rod 252 is fixedly connected to the support base 251 by screws. The output end of the second telescopic rod 252 extends outside the first deck plate 211 and the second deck plate 221. Both the first telescopic rod 241 and the second telescopic rod 252 are configured as electric push rods. The support base 251 includes a second mounting plate 2511 and a second support plate 2512. One end of the second mounting plate 2511 is fixedly connected to the side walls of the first deck plate 211 and the second deck plate 221. Among them, one end of the second mounting plate 2511 is integrally fixedly connected to the side walls of the first deck plate 211 and the second deck plate 221. One end of the second support plate 2512 is fixedly connected to the second mounting plate 2511. Specifically, the second support plate 2512 and the second mounting plate 2511 are of an integral structure, and the second mounting plate 2511 is supported by the second support plate 2512 to reduce the deformation of the second mounting plate 2511. The other end of the second support plate 2512 is fixedly connected to the inner walls of the first deck plate 211 and the second deck plate 221. A support block 253 is fixedly connected to the output end of the second telescopic rod 252. The support block 253 is configured as a frustum of a cone. After the drone assembly 100 takes off from the water surface, the first telescopic rod 241 is opened, and the first telescopic rod 241 retracts. The first telescopic rod 241 drives the second single ear plate 244, and the first double ear plate 242 rotates around the second single ear plate 244. At the same time, the first double ear plate 242 drives the second single ear plate 244 to flip around the hinge point of the first hinge seat 233. The second single ear plate 244 drives the first deck plate 211 and the second deck plate 221 to flip, and the first deck plate 211 and the second deck plate 221 retract, reducing the area of the drone assembly 100 during takeoff and reducing the takeoff resistance. When the drone assembly 100 needs to land, the second telescopic rod 252 is opened, and the second telescopic rod 252 extends. The support block 253 on the output end of the second telescopic rod 252 lands first, and the second telescopic rod 252 cooperates with the first deck plate 211 and the second deck plate 221 to serve as a landing support.

[0047] As Figure 7 and Figure 8As shown, in the prior art, for the unmanned aerial vehicle (UAV) used in basin water resources investigation, during water operations, it is driven by the propeller arranged on the lower side of the rotor 160. As a result, the UAV needs to use two sets of blades, namely the rotor 160 and the propeller, for separate driving, with a relatively large number of blades. The blades of the rotor 160 rotate parallel to the horizontal plane, while the blades of the propeller rotate perpendicular to the horizontal plane, and corresponding power direction conversion is required. This setting with a large number of blades and the need to set up power direction conversion on the rotor 160 makes the structure of the UAV in the prior art for basin water resources investigation more complex than that of ordinary UAVs at the rotor part.

[0048] To solve the above problems, the specific setting method of the present invention is as follows: The drone component 100 includes a drone body 110, a first support rod 120, a third double-ear plate 130, a third single-ear plate 140, a second support rod 150, a rotor 160, and a second telescopic driving member 170.

The four first support rods 120 are fixedly connected to the periphery of the drone body 110 at equal intervals. Among them, the four first support rods 120 and the drone body 110 are of an integral structure. The third double-ear plate 130 is fixedly connected to the end of the first support rod 120. Specifically, the third double-ear plate 130 and the first support rod 120 are of an integral structure. The third single-ear plate 140 is hinged to the third double-ear plate 130. One end of the second support rod 150 is fixedly connected to the third single-ear plate 140. In this embodiment, the second support rod 150 and the third single-ear plate 140 are of an integral structure. The rotor 160 is arranged at the end of the second support rod 150. The specific connection method between the rotor 160 and the second support rod 150 is known to those skilled in the art and will not be described in detail here. It should be noted that the driving motor on the rotor 160 is a waterproof motor, and the electrical connection method between the waterproof motor and the drone body 110 is also known to those skilled in the art and will not be described in detail here. The second telescopic driving member 170 includes a third telescopic driving rod 171, a fourth double-ear plate 172, and a fourth single-ear plate 173. Two of each of the fourth double-ear plate 172 and the fourth single-ear plate 173 are provided. The two fourth double-ear plates 172 are respectively fixedly connected to both ends of the third telescopic driving rod 171. In this embodiment, the two fourth double-ear plates 172 are respectively integrally fixedly connected to both ends of the third telescopic driving rod 171. The third telescopic driving rod 171 is also provided as an electric push rod. The two fourth single-ear plates 173 are respectively hinged to the two fourth double-ear plates 172, and the two fourth single-ear plates 173 are respectively fixedly connected to the lower sides of the first support rod 120 and the second support rod 150. When the first ship plate 211 and the second ship plate 221 are unfolded and the first ship plate 211 and the second ship plate 221 float on the water surface, the third telescopic driving rod 171 is opened, the third telescopic driving rod 171 retracts, the third telescopic driving rod 171 drives the fourth double-ear plate 172 on the second support rod 150 to move, the fourth double-ear plate 172 drives the second support rod 150 to rotate around the third double-ear plate 130, the second support rod 150 drives the rotor 160 to vertically flip, and the rotor 160 extends into the water. At this time, the blades on the rotor 160 can rotate in a direction perpendicular to the water surface. Through the rotation of the four groups of rotors 160, the first ship plate 211 and the second ship plate 221 are driven to sail horizontally. First, the rotor 160 of the original drone component 100 is used as the power for navigation, eliminating the need to set up a propeller again and reducing the use of blades.In a second aspect, only the third telescopic drive rod 171 is used to flip the rotor 160, and there is no need to set up the structure required for power direction conversion again. The structure of the rotor of this basin water resources survey drone is the same as that of a common drone, and only the support rod is segmented and hinged, and the second telescopic drive member 170 is used to drive the flipping, so the structure is simple.

[0049] As Figure 9 and Figure 10 shown, in the related art, when a basin water resources survey drone conducts aerial mapping (using a photographing device to take images), the surveying instrument needs to face the water surface and the direction near the water surface for surveying. When the surveying instrument conducts vertical surveying, and for underwater surveying, it needs to survey all around. When the surveying instrument conducts horizontal surveying, usually two surveying instruments are used for surveying in two directions. It is not convenient to use the same surveying instrument for surveying in two directions. In the design concept of using one surveying instrument to measure two surveying directions, it is necessary to consider raising the surveying instrument above the drone body 110 to increase the height of the surveying instrument and keep the surveying instrument away from the water surface. At the same time, it is also necessary to change the surveying direction of the surveying instrument, which requires two sets of power components, which is likely to increase energy consumption and also likely to increase the weight of the drone body 110.

[0050] To this end, through long-term practical research, the inventor has solved this technical problem. Specifically, the UAV for water resources survey in this basin further includes a surveying and mapping component 300, which includes a first torsion member 310, a mounting member 320, a second torsion member 330, a surveying instrument 340, a first connecting ring 350, a first transmission member 360, and a second transmission member 370. The first torsion member 310 includes a fifth single-ear plate 311, a torsion shaft 312, a fifth double-ear plate 313, and a torsion spring 314. The fifth single-ear plate 311 is fixedly connected to the side wall of the front part of the UAV body 110. Among them, the fifth single-ear plate 311 and the UAV body 110 are of an integral structure. The torsion shaft 312 is fixedly penetrated through the fifth single-ear plate 311. Specifically, the torsion shaft 312 is fixedly penetrated through the fifth single-ear plate 311 by screws. After passing through the side wall of the fifth single-ear plate 311, the screws are threadedly connected to the torsion shaft 312. The fifth double-ear plate 313 is hinged to the torsion shaft 312. The fifth single-ear plate 311 is located inside the fifth double-ear plate 313. The side wall of the front part of the UAV body 110 can block the side wall of the fifth double-ear plate 313. Both ends of the torsion shaft 312 extend out of both sides of the fifth double-ear plate 313. The torsion spring 314 is sleeved on both ends of the torsion shaft 312. One end of the torsion spring 314 is fixedly connected to the fifth double-ear plate 313, and the other end of the torsion spring 314 is fixedly connected to the torsion shaft 312. It should be noted that under the elastic force of the torsion spring 314, the fifth double-ear plate 313 can flip upward until the side wall of the front part of the UAV body 110 blocks the fifth double-ear plate 313. The mounting member 320 includes a mounting rod 321 and a second connecting ring 322. One end of the mounting rod 321 is fixedly connected to the fifth double-ear plate 313. Among them, the mounting rod 321 and the fifth double-ear plate 313 are of an integral structure. The second connecting ring 322 is fixedly connected to the outer wall of one end of the mounting rod 321. Specifically, the second connecting ring 322 and the mounting rod 321 are of an integral structure. The second torsion member 330 is arranged at the other end of the mounting rod 321, and the second torsion member 330 has the same structure as the first torsion member 310. The surveying instrument 340 is fixedly connected to the fifth single-ear plate 311 on the second torsion member 330. The first connecting ring 350 is fixedly connected to one side of the surveying instrument 340. The surveying instrument 340 includes a surveying instrument body 341 and a limiting plate 342. The limiting plate 342 is fixedly connected to one side of the surveying instrument body 341. The fifth double-ear plate 313 on the second torsion member 330 can block the limiting plate 342. Specifically, under the elastic force of the torsion spring 314 on the second torsion member 330, the limiting plate 342 on the surveying instrument body 341 is pressed against the fifth double-ear plate 313.

[0051] Such as Figure 11As shown, the first transmission member 360 includes a first wire guide seat 361, a second wire guide seat 362, a third wire guide seat 363, a third connection ring 364, and a fourth connection ring 365. The first wire guide seat 361 is fixedly connected to the outer wall of the mounting rod 321. Specifically, the first wire guide seat 361 is fixedly connected to the outer wall of the mounting rod 321 by welding. The second wire guide seat 362 is fixedly connected to the upper side of the front part of the UAV body 110. Among them, the second wire guide seat 362 and the UAV body 110 are fixedly connected by welding. The third wire guide seat 363 is fixedly connected to the lower side of the front part of the UAV body 110. It should be noted that the third wire guide seat 363 is fixedly connected to the lower side of the front part of the UAV body 110 by welding. The third connection ring 364 is fixedly connected to the side wall of one of the third double-ear plates 130. In this embodiment, the third connection ring 364 and the third double-ear plate 130 are of an integral structure. The fourth connection ring 365 is fixedly connected to the outer wall of the output end of the corresponding third telescopic driving rod 171. The fourth connection ring 365 is fixedly connected to the output end of the third telescopic driving rod 171 by welding. The third connection ring 364 is located between the fourth connection ring 365 and the rotor 160. A first towing cable is tied to the first connection ring 350. The first towing cable sequentially passes through the first wire guide seat 361, the second wire guide seat 362, the front part of the UAV body 110, the third wire guide seat 363, and the third connection ring 364. After passing through the third connection ring 364, the first towing cable is tied to the fourth connection ring 365.

[0052] As Figure 12As shown, the second transmission member 370 includes a fourth wire guide seat 371, a fifth wire guide seat 372, and a fixed seat 373. The fourth wire guide seat 371 is fixedly connected to the lower side of the UAV body 110. Specifically, the fourth wire guide seat 371 is fixedly connected to the lower side of the UAV body 110 by welding. The fourth wire guide seat 371 is located near the second connection ring 322 of the UAV body 110. The fifth wire guide seat 372 is fixedly connected to one end of the lower front side of the UAV body 110. It should be noted that the fifth wire guide seat 372 is fixedly connected to one end of the lower front side of the UAV body 110 by welding. The fixed seat 373 is fixedly connected to the inner wall of the first ship plate 211. Among them, the fixed seat 373 and the first ship plate 211 are fixed by welding. A second towing cable is tied to the second connection ring 322. The second towing cable passes through the lower end and the upper end of the fourth wire guide seat 371 and the fifth wire guide seat 372 in sequence. After passing through the fifth wire guide seat 372, the second towing cable is tied to the fixed seat 373. The lower end of the fourth wire guide seat 371 is lower than the second connection ring 322. When the first ship plate 211 and the second ship plate 221 are unfolded, one end of the second towing cable moves with the fourth wire guide seat 371 on the first ship plate 211, and the second towing cable gradually relaxes, releasing the tension on the second connection ring 322. Under the elastic force of the torsion spring 314 on the first torsion member 310, the mounting rod 321 flips up, and the mounting rod 321 drives the surveying instrument body 341 to flip up, so that the surveying instrument body 341 flips to the upper side of the UAV body 110. After the first ship plate 211 and the second ship plate 221 enter the water, the output end of the third telescopic drive rod 171 retracts. The third telescopic drive rod 171 drives the rotor 160 to flip into the water. The output end of the third telescopic drive rod 171 drives the fourth connection ring 365. The fourth connection ring 365 pulls the first towing cable. The first towing cable slides along the third connection ring 364, the third wire guide seat 363, the second wire guide seat 362, and the first wire guide seat 361 in sequence, and changes the movement direction of the first towing steel. The tightened first towing cable pulls the first connection ring 350, and then pulls the surveying instrument body 341 to rotate around the fifth double-ear plate 313 on the second torsion member 330. At this time, the elastic force of the torsion spring 314 on the second torsion member 330 increases until the surveying instrument body 341 faces the horizontal direction. Before the water resources survey UAV takes off, the output end of the third telescopic drive rod 171 pushes out. The output end of the third telescopic drive rod 171 pushes the rotor 160 back to its original position. The output end of the third telescopic drive rod 171 drives the fourth connection ring 365. The first towing cable on the fourth connection ring 365 gradually relaxes. Under the elastic force of the torsion spring 314 on the second torsion member 330, the surveying instrument body 341 flips until the limiting plate 342 presses tightly against the fifth double-ear plate 313. At this time, the surveying part of the surveying instrument body 341 faces upward, and the rotor 160 is turned on.After the drone for the water resources survey in this basin takes off, the first boat plate 211 and the second boat plate 221 are retracted. The first boat plate 211 drives the fixed seat 373, and the fixed seat 373 pulls the second towing steel cable. The second towing steel cable slides along the upper and lower ends of the fifth cable guide seat 372 and the fourth cable guide seat 371 in sequence, and changes the movement direction of the second towing steel cable. The second towing steel cable pulls the second connecting ring 322, and the second connecting ring 322 pulls the mounting rod 321 to rotate. At the same time, the fifth double-ear plate 313 on the first torsion member 310 rotates around the fifth single-ear plate 311. At this time, the elastic force of the torsion spring 314 on the first torsion member 310 increases until the mounting rod 321 flips to the vertical state. At this time, the mapping instrument body 341 faces the ground for mapping in the vertical direction. Through one mapping instrument body 341, mapping in the vertical direction during flight and mapping in the horizontal direction during water surface navigation can be carried out. There is no need to set two mapping instrument bodies 341. At the same time, when the height and mapping direction of the mapping instrument body 341 change, they are driven by the power when the first boat plate 211 flips and the power when the rotor 160 flips. The actions of the mapping instrument body 341, the first boat plate 211, and the rotor 160 cooperate with each other. That is, during water navigation, the mapping instrument body 341 conducts horizontal mapping, and during flight, it conducts vertical mapping. There is no need to introduce a new driving device, reducing the use of power components, and thus reducing the weight increase and energy consumption increase caused by setting power components.

[0053] As Figure 13 shown, the fourth cable guide seat 371 includes two first connecting rods 3711 and four first fixing rods 3712. The four first fixing rods 3712 are respectively fixedly connected between the two first connecting rods 3711, and the four first fixing rods 3712 are symmetrically arranged at the upper and lower ends of the two first connecting rods 3711. The second towing steel cable first passes through the two first fixing rods 3712 at the lower end of the first connecting rod 3711, and then passes through the two first fixing rods 3712 at the upper end of the first connecting rod 3711, which is convenient for guiding the steel cable.

[0054] As Figure 14 shown, the first cable guide seat 361 includes two second connecting rods 3611 and two second fixing rods 3612. The two second fixing rods 3612 are respectively fixedly connected between the two second connecting rods 3611. The second cable guide seat 362, the third cable guide seat 363, the fifth cable guide seat 372, and the fixed seat 373 have the same structure, which is convenient for guiding the steel cable. The first towing steel cable and the second towing steel cable pass through between the two second fixing rods 3612. The relative sides of the first connecting rod 3711 and the second connecting rod 3611 are set to be arc-shaped to reduce the wear of the steel cable by the first connecting rod 3711 and the second connecting rod 3611.

[0055] Specifically, the working principle of the UAV for watershed water resources investigation: When the UAV needs to conduct water mapping, control the UAV component 100 to approach the water surface, turn on one of the first telescopic driving members 240. The first telescopic driving member 240 drives the first boat plate 211 to flip around the lower end of the support frame 230 until the first boat plate 211 is in a horizontal position. Then turn on the other first telescopic driving member 240. The first telescopic driving member 240 drives the second boat plate 221 to flip around the lower end of the support frame 230. The first telescopic driving member 240 pushes the clamping strip 222 on the second boat plate 221 into the clamping groove 212 until the sealing strip 223 is tightly pressed against the clamping groove 212. Then control the UAV component 100 to make the first boat plate 211 and the second boat plate 221 float on the water surface. If there is a leak, the water first enters the first boat plate 211 and the second boat plate 221, and the water does not directly enter the UAV component 100. At this time, the UAV component 100 can be controlled to fly up, retract the first boat plate 211 and the second boat plate 221, deploy the first boat plate 211 and the second boat plate 221 again, make the clamping strip 222 press into the clamping groove 212 again, and try whether it is sealed again. If the leak problem is solved, the operation can continue. If the problem is not solved, it can be controlled to fly back for repair. The first boat plate 211 and the second boat plate 221 are stronger than the floating airbags and are not easily damaged.

[0056] After the UAV component 100 takes off from the water surface, turn on the first telescopic rod 241. The first telescopic rod 241 retracts. The first telescopic rod 241 drives the second single ear plate 244, and the first double ear plate 242 rotates around the second single ear plate 244. At the same time, the first double ear plate 242 drives the second single ear plate 244 to flip around the hinge point of the first hinge seat 233. The second single ear plate 244 drives the first boat plate 211 and the second boat plate 221 to flip, and the first boat plate 211 and the second boat plate 221 are retracted, reducing the area of the UAV component 100 during takeoff and reducing the takeoff resistance. When the UAV component 100 needs to land, turn on the second telescopic rod 252. The second telescopic rod 252 extends. The support block 253 on the output end of the second telescopic rod 252 lands first, and the second telescopic rod 252 cooperates with the first boat plate 211 and the second boat plate 221 as the landing support.

[0057] After the first hull plate 211 and the second hull plate 221 are unfolded and the first hull plate 211 and the second hull plate 221 float on the water surface, the third telescopic drive rod 171 is opened, the third telescopic drive rod 171 retracts, the third telescopic drive rod 171 drives the movement of the fourth double-ear plate 172 on the second support rod 150, the fourth double-ear plate 172 drives the second support rod 150 to rotate around the third double-ear plate 130, the second support rod 150 drives the rotor 160 to vertically flip, and the rotor 160 extends into the water. At this time, the blades on the rotor 160 can rotate in a direction perpendicular to the water surface. Through the rotation of the four groups of rotors 160, the first hull plate 211 and the second hull plate 221 are driven to sail horizontally. Firstly, the rotor 160 of the original UAV component 100 is used as the power for sailing, eliminating the need to set up a propeller again and reducing the use of blades. Secondly, only the rotor 160 is flipped by the third telescopic drive rod 171, and there is no need to set up a structure for power direction conversion again. The UAV rotor for the water resources survey in this basin has the same structure as that of an ordinary UAV, and only the support rod is segmented and hinged and driven to flip by the second telescopic drive member 170, with a simple structure.

[0058] When the first hull plate 211 and the second hull plate 221 are unfolded, one end of the second towing cable moves along with the fourth cable guide seat 371 on the first hull plate 211, and the second towing cable gradually becomes slack, releasing the tension on the second connecting ring 322. Under the elastic force of the torsion spring 314 on the first torsion member 310, the mounting rod 321 flips up, and the mounting rod 321 drives the surveying instrument body 341 to flip up, so that the surveying instrument body 341 flips to the upper side of the UAV body 110. After the first hull plate 211 and the second hull plate 221 enter the water, the output end of the third telescopic drive rod 171 retracts, and the third telescopic drive rod 171 drives the rotor 160 to flip into the water. The output end of the third telescopic drive rod 171 drives the fourth connecting ring 365, and the fourth connecting ring 365 pulls the first towing cable. The first towing cable slides along the third connecting ring 364, the third cable guide seat 363, the second cable guide seat 362 and the first cable guide seat 361 in sequence, and changes the movement direction of the first towing cable. The tightened first towing cable pulls the first connecting ring 350, and further pulls the surveying instrument body 341 to rotate around the fifth double ear plate 313 on the second torsion member 330. At this time, the elastic force of the torsion spring 314 on the second torsion member 330 increases until the surveying instrument body 341 faces the horizontal direction. Before the UAV for basin water resources survey takes off, the output end of the third telescopic drive rod 171 extends, and the output end of the third telescopic drive rod 171 pushes the rotor 160 back to its original position. The output end of the third telescopic drive rod 171 drives the fourth connecting ring 365, and the first towing cable on the fourth connecting ring 365 gradually relaxes. Under the elastic force of the torsion spring 314 on the second torsion member 330, the surveying instrument body 341 flips until the limiting plate 342 presses tightly against the fifth double ear plate 313. At this time, the surveying part of the surveying instrument body 341 faces upward. After the rotor 160 is turned on and the UAV for basin water resources survey takes off, the first hull plate 211 and the second hull plate 221 are retracted. The first hull plate 211 drives the fixed seat 373, and the fixed seat 373 pulls the second towing cable. The second towing cable slides along the fifth cable guide seat 372 and the upper and lower ends of the fourth cable guide seat 371 in sequence, and changes the movement direction of the second towing cable. The second towing cable pulls the second connecting ring 322, and the second connecting ring 322 pulls the mounting rod 321 to rotate. At the same time, the fifth double ear plate 313 on the first torsion member 310 rotates around the fifth single ear plate 311. At this time, the elastic force of the torsion spring 314 on the first torsion member 310 increases until the mounting rod 321 flips to the vertical state. At this time, the surveying instrument body 341 faces the ground for vertical direction surveying. The vertical direction surveying during flight and the horizontal direction surveying during water surface navigation can be carried out by one surveying instrument body 341 without setting two surveying instrument bodies 341. At the same time, when the height and surveying direction of the surveying instrument body 341 change, they are driven by the power when the first hull plate 211 flips and the power when the rotor 160 flips.The movement of the surveying instrument body 341 cooperates with the movement of the first ship board 211 and the rotor 160. When sailing in water, the surveying instrument body 341 conducts horizontal surveying, and when flying, it conducts vertical surveying. There is no need to introduce a new driving device, which reduces the use of power components, and further reduces the increase in weight and energy consumption caused by the setting of power components.

[0059] It should be noted that the specific model specifications of the electric push rod and the torsion spring 314 need to be selected according to the actual specifications of the device.
