As shown in fig. 1, an unmanned aerial vehicle water intake system mainly comprises a winch 1 and a water intake bottle 2.
The hoist 1 includes a housing 11, as shown in fig. 2, a spool 12 is provided in the housing 11, and a suspension wire is wound around the spool 12, and the suspension wire is led out from below the housing 11 and then connected to the water taking bottle 2. In this embodiment, the spool 12 has a wire paying-out and winding-up function. When the wire spool 12 pays out, the water taking bottle 2 descends relative to the winch 1; when the wire spool 12 is wound up, the water bottle 2 is lifted up relative to the hoist 1. In addition, the upper end of the shell 11 is fixedly arranged at the bottom of the unmanned aerial vehicle, so that the water taking system is connected with the unmanned aerial vehicle.
As shown in fig. 1, the water intake bottle 2 includes a bottle cap 21, a bottle body 22, and a bottle bottom 23, and the bottle cap 21 and the bottle bottom 23 are provided with upper and lower ends of the bottle body 22, respectively. Specifically, a suspension wire led out from the lower side of the housing 11 is connected to the cap 21.
In order to be able to sample better, both the bottle cap 21 and the bottle bottom 23 are modified in this technical solution. Sampling means taking water by the water taking bottle 2.
As shown in fig. 4, a plurality of openings 211 are formed in the bottle cap 21, each opening 211 is movably hinged with a movable cover 212, and after the movable covers 212 are combined on the openings 211, the bottle cap 21 forms a truncated cone-shaped structure. The truncated cone-shaped structure can reduce the resistance of the water taking bottle 2 in water.
As shown in fig. 5, a circular water inlet 231 is formed in the bottom surface of the bottle bottom 23, a circular baffle 232 is arranged above the water inlet 231, the radius of the water inlet 231 is smaller than that of the circular baffle 232, a plurality of limiting components 233 are arranged on the upper surface of the bottom surface of the bottle bottom 23, a movable area is surrounded by the plurality of limiting components 233 above the water inlet 231, and the circular baffle 232 is limited in the movable area by the limiting components 233.
During sampling, in the process of descending the water taking bottle 2, the water taking bottle 2 slowly enters water, when the bottle bottom 23 contacts the water surface, the circular baffle 232 is pushed by the water to ascend, the water taking bottle 2 continues to descend, and the water is poured into the water taking bottle 2 from the space between the water inlet 231 and the circular baffle 232; in the process of lifting the water bottle 2, no water pushes the circular baffle 232 from bottom to top, the circular baffle 232 is lowered by self gravity and the gravity of the water above the circular baffle 232, and the circular baffle 232 can be used for blocking the water inlet 231 to prevent water leakage because the radius of the water inlet 231 is smaller than that of the circular baffle 232.
After a sufficient amount of water is collected in the water taking bottle 2, a wire winding is needed to pull the water taking bottle 2 back to the unmanned aerial vehicle. The process of pulling the water bottle 2 back to the unmanned aerial vehicle is divided into three stages, wherein the first stage is ascending under the water surface, the second stage is water outlet, and the third stage is ascending under the water surface.
When the bottle cap 21 of the water taking bottle 2 is of a flat plate structure, the resistance to the water taking bottle 2 when rising under the water surface and discharging water is larger, especially when the bottle cap 21 discharges water, the resistance to the water taking bottle 2 suddenly increases first, and when the bottle cap 21 is exposed out of the water surface, the resistance to the water taking bottle 2 suddenly decreases again due to the buoyancy relation. Therefore, when the bottle cap 21 of the water bottle 2 is of a flat plate structure, the stability of the unmanned aerial vehicle is greatly affected, which is not beneficial to the flight safety.
In this technical scheme, bottle lid 21 part of water intaking bottle 2 is round platform column structure, through such setting, has reduced the resistance that the in-process water intaking bottle 2 that retrieves water bottle 2 received greatly, has also reduced the variation range of bottle lid 21 in-process resistance simultaneously, improves unmanned aerial vehicle's stability and security.
As shown in fig. 5, the limit assembly 233 includes a vertical portion having one end connected to the upper surface of the bottom surface of the bottle bottom 23 and the other end connected to a horizontal portion disposed above the water inlet 231 along the circumferential direction of the water inlet 231. In brief, the limiting members 233 are arranged in a 7 shape, and the plurality of limiting members 233 collectively define the circular baffle 232 within the active area. The vertical portion and the horizontal portion are integrally formed, and the vertical portion is fixedly arranged on the upper surface of the bottom surface of the bottle bottom 23 through bolts. Specifically, three limit members 233 are provided, and the three limit members 233 are uniformly distributed on the upper surface of the bottom surface of the bottle bottom 23.
Several spacing assemblies 233 enclose an active area through the vertical, horizontal and bottom surfaces of the bottle bottom 23, and the circular baffles 232 are movably disposed in the active area. Therefore, when the water inlet 231 is filled with water, the circular baffle 232 is pushed upwards, so that water is conveniently filled; when sampling is completed, the circular baffle 232 is pushed down and covers the water inlet 231 to prevent leakage.
Preferably, as shown in fig. 3, a truncated cone-shaped concave portion 13 is arranged at the bottom of the housing 11, the shape of the concave portion 13 is matched with that of the bottle cap 21, and the water bottle 2 is sleeved into the concave portion 13 through the bottle cap 21 and is fixed below the winch 1.
In order to enable the water bottle 2 to be better connected with the winch 1, a connecting port is formed in the center of the bottle cap 21, and a hanging wire led out from the lower side of the shell 11 is connected with the bottle cap 21 through a connecting piece.
As shown in fig. 6, the connecting member includes an outer sleeve 3, a connecting vertebral body 4, a binding-wire fastener 5, and a connecting portion 6. In the present solution, the connecting vertebral body 4 is a soft elastic connecting vertebral body.
The inside of the connecting cone 4 is provided with a tiny pore along the central axis, and the pore penetrates through the upper end and the lower end of the connecting cone 4 from top to bottom. After the hanging wire is led out from the lower part of the unmanned aerial vehicle, the hanging wire penetrates into the fine hole from the upper end of the connecting cone 4 and penetrates out from the lower end of the connecting cone 4, and the hanging wire penetrating out from the lower end of the connecting cone 4 is further fixedly connected with the wire binding fastener 5.
The binding-wire fastener 5 functions to fix the suspension wire passing through the connecting vertebral body 4. The hanging wire passes through the connecting cone 4 and then is bound on the binding wire fastener 5, and the hanging wire is in a loose state. If the hanging wire is tightened, the hanging wire drives the wire binding fastener 5 to move upwards, the wire binding fastener 5 is gradually abutted against the lower end of the connecting cone 4, and if the hanging wire is further tightened, the hanging wire drives the wire binding fastener 5 to extrude the connecting cone 4, so that the hanging wire is buffered.
The outer sleeve 3 has a cylindrical structure. When the hanging wire is tightened, the wire binding fastener 5 is driven to move upwards, so that the connecting cone 4 and the wire binding fastener 5 are completely sleeved in the outer sleeve 3, then the connecting part 6 is connected with the lower end of the outer sleeve 3, and the connecting part 6 can seal the connecting cone 4 and the wire binding fastener 5 in the outer sleeve 3.
The connecting part 6 has two functions, namely, the connecting cone 4 and the binding wire fastener 5 are sealed in the outer sleeve 3, and the water taking bottle 2 is connected. In the case that the connecting part 6 is fixedly connected with the lower end of the outer sleeve 3, the water taking bottle 2 is mounted on the unmanned aerial vehicle only by connecting the connecting part 6 with the water taking bottle 2.
After the water taking bottle 2 is arranged on the unmanned aerial vehicle, in the water taking process, the hanging wire pays out, the water taking bottle 2 is subjected to the action of gravity to provide a downward pulling force for the whole connecting piece, and the whole connecting piece gradually descends until the sampling action is completed. After the sampling action is finished, the hanging wire is wound, and as the volume of the wire binding fastener 5 is far smaller than the radius of the pore inside the connecting cone 4, the wire binding fastener 5 is gradually abutted to the lower end of the connecting cone 4 along with the winding, and then the connecting piece of the water taking bottle 2 of the whole unmanned aerial vehicle is driven to ascend together with the water taking bottle 2, so that water taking is finished. At the moment, the unmanned aerial vehicle is operated to return to the voyage.
Preferably, in order to make the installation of the suspension wire more convenient and quick, the lower end of the outer sleeve 3 is provided with an internal thread, the upper end of the connecting portion 6 is provided with an external thread, and the connecting portion 6 is in threaded connection with the outer sleeve 3 through the internal thread and the external thread. The connection part 6 is only required to be screwed on the lower end of the outer sleeve 3 to complete the installation.
In order to enable the connecting portion 6 to be better fixed with the water taking bottle 2, the lower end of the connecting portion 6 is provided with a clamping assembly 61, the clamping assembly 61 is connected with the water taking bottle 2 through a connecting port arranged on the bottle cap 21 of the water taking bottle 2, the shape of the clamping assembly 61 is identical to that of the connecting port, after the clamping assembly 61 stretches into the connecting port, the connecting portion 6 is rotated again to enable the clamping assembly 61 to be staggered with the connecting port, and therefore connection of the clamping assembly 61 and the water taking bottle 2 is completed. Specifically, as shown in fig. 7 and 8, the clip assembly 61 has a petal-like structure.
In addition, a groove 62 is formed in the middle of the connecting portion 6, the groove 62 is disposed between the external thread and the clamping assembly 61, and an elastic ring 63 is disposed in the groove 62.
The engaging member 61 has a petal-shaped structure, and correspondingly, as shown in fig. 10, a petal-shaped connection port is formed in the cap 21 of the water bottle 2. After the connecting part 6 is embedded into the connecting port on the bottle cap 21 of the water bottle 2 through the clamping assembly 61, the connecting part 6 is rotated, so that the clamping assembly 61 is staggered with the connecting port, and the connection between the clamping assembly 61 and the water bottle 2 is completed. To enable the clamping assembly 61 to be inserted into the connection port, the size of the connection port is slightly larger than the size of the clamping assembly 61.
