Technical Field

[0001] The present application relates to the technical field of sewage collection, and in particular to an unmanned aerial vehicle flying device for river management that facilitates sewage sampling. Background Art

[0002] With the acceleration of global modernization, many jobs that require manpower have been gradually replaced by machines. The most obvious one is the collection of sewage samples. Modern sewage sample collection is mostly done by using drones to fly to specific waters for collection. However, existing drones can only collect samples once. When collecting samples in multiple waters, the process is cumbersome, time-consuming and labor-intensive. Summary of the invention

[0003] In order to improve the efficiency of sewage collection, the present application provides a drone flying device for river management that is convenient for sewage sampling.

[0004] The above technical objectives of this application are achieved through the following technical solutions: A drone flying device for river management that is convenient for sewage sampling includes a drone, a turntable is rotatably connected below the drone, a plurality of collection pipes for sewage collection are arranged around the turntable, a collector for allowing sewage to enter the collection pipe is arranged below the drone, and the turntable is connected to a driving structure for driving the turntable to rotate.

[0005] By adopting the above scheme, when sewage collection is needed, the drone is stopped above the water surface, and the collection tube is inserted into the water surface. The collector fills the collection tube below it with sewage, thereby realizing sewage collection. Then the drone goes to the next place to collect sewage, and the driving structure drives the turntable to rotate, so that another collection tube moves to the bottom of the collector. Then the above operation is repeated, and sewage can be collected from multiple places, thereby improving sewage collection efficiency.

[0006] Optionally, the collector includes a pushing cylinder, a sliding cover is provided above the collecting tube, the sliding cover can slide along the collecting tube, and a collecting door that can be opened and closed is provided below the collecting tube. When the collecting tube moves below the pushing cylinder, the pushing cylinder can drive the sliding cover to slide in the collecting tube.

[0007] By adopting the above scheme, when sewage collection is required, the collection door is opened, pushing the cylinder piston rod to extend, thereby compressing the gas in the collection pipe, so that the gas in the collection pipe flows out, and then the piston rod is retracted, and under the influence of the air pressure, the sewage enters the collection pipe at the collection door, and then the collection door is closed, so that the sewage is collected in the collection pipe, thereby realizing the collection of sewage.

[0008] Optionally, a T-shaped slide rail is provided above the slide cover, and a T-shaped block is fixedly connected to the piston rod of the push cylinder. When the collecting tube moves to the bottom of the push cylinder, the T-shaped block slides into the T-shaped slide rail.

[0009] By adopting the above solution, when the collection pipe moves to the bottom of the pushing cylinder, the T-shaped slider slides into the T-shaped slide rail, thereby clamping the sliding cover with the pushing cylinder, so that when the piston rod of the cylinder is retracted, the pushing cylinder can drive the sliding cover to move together, allowing the sewage to enter the collection pipe more smoothly.

[0010] Optionally, an elastic member is provided in the collecting tube, one end of the elastic member is connected to the sliding cover, and the other end of the elastic member is connected to the collecting tube.

[0011] By adopting the above solution, a spring is provided to further ensure that the sliding cover can return to the initial position, and the spring can limit the initial position of the sliding cover, so that the T-shaped slider can slide into the T-shaped slide rail more smoothly, avoiding displacement of the sliding cover causing misalignment of the T-shaped slider and the T-shaped slide rail.

[0012] Optionally, the collecting door includes a liquid inlet one-way door that allows sewage to enter the collecting pipe, and the sliding door is provided with an air outlet one-way door that allows air in the collecting pipe to be discharged.

[0013] By adopting the above scheme, when the piston rod of the push cylinder is extended, the sliding cover compresses the air in the collecting pipe, causing the air in the collecting pipe to flow out at the air outlet one-way door, and then the sliding cover slides in the opposite direction to reduce the air pressure in the collecting pipe, allowing the sewage to enter the collecting pipe at the liquid inlet one-way door, thereby realizing the collection of sewage.

[0014] Optionally, a pin groove is provided on the upper surface of the sliding cover, and a pin is slidably connected in the pin groove. One end of the pin is located in the T-shaped slide rail and is an inclined surface. The end of the pin facing away from the T-shaped slide rail is fixedly connected to a pin spring. The end of the pin spring facing away from the pin is fixedly connected to the pin groove, and one end of the pin connected to the pin spring is fixedly connected to a connecting rod. The end of the connecting rod facing away from the pin is connected to a helical rack. A transmission cavity is provided in the sliding cover, and a helical gear is arranged in the transmission cavity. The helical gear meshes with the helical rack. The helical gear is connected to a door panel, and the door panel is located opposite to the one-way air outlet door. A cavity sufficient for the door panel to slide is provided on the inner side of the sliding cover.

[0015] By adopting the above scheme, when the collecting pipe does not correspond to the pushing cylinder, the pin spring is at its original length, and the door plate blocks the door of the one-way air outlet door to prevent the one-way air outlet door from opening and sewage entering the collecting pipe; when the collecting pipe is facing the pushing cylinder, the T-shaped slider presses the bayonet pin completely into the pin groove, thereby driving the connecting rod and the bevel rack to move, thereby driving the bevel gear to rotate, thereby driving the door plate to open, so that the one-way air outlet door can be used normally.

[0016] Optionally, a lower cover is provided below the collecting tube, the lower cover is threadedly connected to the collecting tube, and a liquid inlet one-way door is provided inside the lower cover.

[0017] By adopting the above solution, the liquid inlet one-way door can be easily disassembled and replaced, and the operator can more conveniently take out the sewage in the collection pipe.

[0018] Optionally, the lower cover is provided with a sliding hole, the liquid inlet one-way door is fixedly connected to a sliding rod, the sliding rod is slidably connected in the sliding hole, the sliding rod is fixedly connected to a clamping plate at one end facing away from the air outlet one-way door, the clamping plate is perpendicular to the sliding rod, the drone is connected to a clamping rod which is one less than the collecting tube, the clamping rod is connected to an axle rod at one end facing away from the drone, the axle rod is connected to a roller, each roller corresponds to a collecting tube except the one facing the pushing cylinder, and the roller is located between the lower rod and the clamping plate.

[0019] By adopting the above solution, the roller slides to the position between the lower plate and the clamping rod, thereby blocking the liquid inlet one-way door, thereby preventing sewage from entering other collecting pipes when the collecting pipe facing the pushing cylinder is filled.

[0020] Optionally, a rubber sealing ring is provided at the connection between the liquid inlet one-way door and the lower cover.

[0021] By adopting the above solution, the sealing effect of the liquid inlet one-way door is improved, and the liquid inlet one-way door has a certain movable margin when sealing, making it easier for the roller to slide between the lower plate and the clamping rod.

[0022] Optionally, an inflatable airbag is provided under the drone. When the inflatable airbag is filled with gas, when the drone stops on the water surface, the water level just covers the collection pipe at the lower end.

[0023] By adopting the above solution, the drone can stay on the water surface more stably, and the distance between the drone and the water surface can be conveniently controlled so that the collection pipe can collect sewage, thereby improving the effect of sewage collection.

[0024] In summary, this application has the following technical effects: 1. By setting up a turntable and multiple collection pipes, the drone can collect sewage from multiple locations, thereby improving the efficiency of sewage collection; 2. By setting up a T-shaped slide rail and a T-shaped slider, when the piston of the push cylinder is retracted, the push cylinder can also drive the slide cover to move; 3. By setting up an inflatable airbag, the drone can stay on the water surface more conveniently, making sewage collection more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The present application is further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1 A drone flight device for river management that is convenient for sewage sampling includes a drone 1, a turntable 3 is rotatably connected below the drone 1, a plurality of collection pipes 4 for sewage collection are arranged around the turntable 3, a collector for allowing sewage to enter the collection pipe 4 is arranged below the drone 1, and the turntable 3 is connected to a driving structure for driving the turntable 3 to rotate. When sewage collection is required, the drone 1 is stopped above the water surface, the collection pipe 4 is inserted into the water surface, and the collector fills the collection pipe 4 below it with sewage, thereby realizing sewage collection. Then the drone 1 goes to the next place to collect sewage, and the driving structure drives the turntable 3 to rotate, so that another collection pipe 4 moves to the bottom of the collector. Then the above operation is repeated, and sewage can be collected from multiple places, thereby improving the efficiency of sewage collection.

[0029] Reference Figure 1 The driving structure includes a driving motor 2, which is fixedly connected to the bottom of the drone 1, with the output shaft of the driving motor 2 facing downward, and the output shaft of the driving motor 2 is fixedly connected to the turntable 3. A plurality of threaded holes are provided near the edge of the turntable 3, and the threaded holes are arranged in a circular array. Threads are provided on the outer side of the collecting tube 4, and the collecting tube 4 passes through the threaded holes and is threadedly connected to the turntable 3, so that the operator can remove the collecting tube 4 and the liquid in the collecting tube 4 can be inspected conveniently.

[0030] Reference Figure 1 and Figure 3 The collector includes a push cylinder 5, which is fixedly connected to the bottom of the drone 1, and the piston rod of the push cylinder 5 is downward, and the push cylinder 5 is facing a threaded hole. The collection pipe 4 is a hollow tube body, and a sliding cover 6 is slidably connected to one end of the collection pipe 4. The surface of the sliding rod 711 is provided with a one-way gas outlet door 66 for discharging the gas in the collection pipe 4. A lower cover 7 is threadedly connected to the end of the collection pipe 4 away from the sliding cover 6, and the lower cover 7 is connected to a one-way liquid inlet door 71 for allowing sewage to enter the collection pipe 4. An elastic member 41 is provided in the collection pipe 4, and the two ends of the elastic member 41 are respectively connected to the sliding cover 6 and the lower cover 7. When sewage collection is required, the collection pipe 4 that needs to collect sewage is rotated to the bottom of the push cylinder 5, and then the piston rod of the push cylinder 5 is extended, so that the slide cover 6 slides into the collection pipe 4, and the elastic member 41 is compressed at the same time, so that the gas in the collection pipe 4 is compressed, so that the gas in the collection pipe 4 flows out at the gas outlet one-way door 66, and then the piston rod of the push cylinder 5 is retracted, and the spring rebounds, so that the slide cover 6 moves toward the push cylinder 5. At this time, the air pressure in the collection pipe 4 is reduced, so that the sewage enters the collection pipe 4 from the liquid inlet one-way door 71 until the spring shrinks to its original length. At this time, the push cylinder 5 shrinks to the limit, so that the sewage is collected. In addition, due to the presence of the elastic member 41, there may still be some air in the collection pipe 4. At this time, it is only necessary to extend a part of the output shaft of the push cylinder 5 again to completely discharge the gas in the collection pipe 4, and then the piston cover of the push cylinder 5 is retracted, so that the collection pipe 4 is completely filled with gas.

[0031] Reference Figure 2 and Figure 3 , the piston rod of the push cylinder 5 is connected with a T-shaped slider 51, which includes two cylinders with different diameters. A T-shaped slide rail 61 is arranged above the slide cover 6. When the collection pipe 4 rotates to the bottom of the driving cylinder, the T-shaped slider 51 slides into the T-shaped slide rail 61. Since the movement path of the collection pipe 4 is circular, the route of the T-shaped slide rail 61 is arc-shaped. When sewage is collected, the T-shaped slider 51 slides into the T-shaped slide rail 61, and then the piston rod of the push cylinder 5 drives the slide bar 711 to move downward. When the piston of the push cylinder 5 retracts, since the T-shaped slide rail 61 clamps the T-shaped slider 51, the push cylinder 5 drives the slide cover 6 to move, making sewage collection more convenient. After the sewage collection is completed, the T-shaped slider 51 slides out on the slide rail. In addition, when the elastic member 41 is at its original length, the T-shaped slider 51 is directly opposite to the T-shaped slide rail 61, so that the T-shaped slider 51 can slide into the T-shaped slide rail 61 more smoothly.

[0032] Reference Figure 3 , Figure 4 and Figure 5A pin groove 64 is provided at the center of the upper surface of the sliding cover 6, and a bayonet 62 is slidably connected in the pin groove 64. A pin spring 621 is fixedly connected to one end of the bayonet 62 near the bottom of the pin groove 64. The end of the bayonet 62 away from the pin spring 621 is tapered, and when the pin spring 621 is at its original length, the tapered end of the bayonet 62 extends out of the pin groove 64, and one end of the bayonet 62 connected to the pin spring 621 is fixedly connected to a connecting rod 622. A transmission chamber 65 is provided inside the sliding cover 6, and the end of the connecting rod 622 away from the bayonet 62 is located in the transmission chamber 65, and this end of the connecting rod 622 is fixedly connected to a bevel rack 623, and a bevel gear 63 is rotatably connected in the transmission chamber 65, and the bevel gear 63 is meshed with the bevel rack 623, and the bevel gear 63 is fixedly connected to a door plate 631, and the transmission chamber 65 is communicated with the air outlet one-way door 66, so that the door plate 631 can block or open the air outlet one-way door 66. When the collecting pipe 4 is not corresponding to the pushing cylinder 5, the pin spring 621 is at its original length, and the door plate 631 blocks the door of the one-way air outlet door 66 to prevent the gas in the collecting pipe 4 from overflowing, thereby preventing the one-way air outlet door 66 from opening to allow sewage to enter the collecting pipe 4; when the collecting pipe 4 is facing the pushing cylinder 5, the T-shaped slider 51 presses the bayonet 62 completely into the pin groove 64, thereby driving the connecting rod 622 and the bevel rack 623 to move, thereby driving the bevel gear 63 to rotate, thereby driving the door plate 631 to open, so that the one-way air outlet door 66 can be used normally.

[0033] Reference Figure 6 A sealing rubber ring is provided between the lower cover 7 and the liquid inlet one-way door 71. The sealing rubber ring makes the sealing of the liquid inlet one-way door 71 more tight, and the sealing rubber ring also allows the liquid inlet one-way door 71 to have a certain displacement margin when sealing. The lower cover 7 is provided with a sliding hole 72, and the liquid inlet one-way door 71 is fixedly connected with a sliding rod 711. The sliding rod 711 is slidably connected in the sliding hole 72. The end of the sliding rod 711 away from the gas outlet one-way door 66 is fixedly connected with a clamping plate 712. The clamping plate 712 is perpendicular to the sliding rod 711. The drone 1 is connected with a clamping rod 8 which is one less than the collection tube 4. The end of the clamping rod 8 away from the drone 1 is connected with a shaft 81. The shaft 81 is connected with a roller 82. Each roller 82 corresponds to a collection tube 4 except the one corresponding to the push cylinder 5. The roller 82 is located between the lower rod and the clamping plate 712. The roller 82 slides to a position between the lower plate and the clamping rod, thereby clamping the liquid inlet one-way door 71, so that the liquid inlet one-way door 71 is in a sealed state, thereby preventing sewage from entering other collecting pipes 4 when the collecting pipe 4 facing the pushing cylinder 5 is filled.

[0034] Reference Figure 1An inflatable airbag 9 is arranged under the drone 1. When the inflatable airbag 9 is filled with gas, when the drone 1 stops on the water surface, the water level just covers the collecting pipe 4 at the lower end, and the inflatable airbag 9 is connected to an air pump that can inflate and deflate the inflatable airbag 9. The inflatable airbag 9 enables the drone 1 to stay on the water surface more stably, and it is convenient to control the distance between the drone 1 and the water surface, so that the collecting pipe 4 can collect sewage, thereby improving the effect of sewage collection.

[0035] The specific implementation principle of the present application is as follows: when sewage treatment is required, the inflatable airbag 9 is inflated, and then the drone 1 is stopped on the water surface, so that part of the collection pipe 4 enters the water, and the driving motor 2 drives the disc to rotate, so that the T-shaped slider 51 slides into the T-shaped slide rail 61. At the same time, the T-shaped slider 51 completely presses the bayonet 62 into the bayonet 62, thereby driving the connecting rod 622 and the bevel rack 623 to move, thereby driving the bevel gear 63 to rotate, thereby driving the door plate 631 to open; then the piston rod of the cylinder 5 is pushed out, driving the sliding cover 6 below it to move downward, so that the gas in the collection pipe 4 flows out at the gas outlet one-way door 66, and then the piston rod is retracted, driving the sliding cover 6 to move, so that the gas in the collection pipe 4 is compressed less, so that the sewage enters the collection pipe 4 at the liquid inlet one-way door 71, thereby realizing the collection of sewage, and then the drone 1 repeats the above operation to collect the next sewage, thereby improving the efficiency of sewage collection.

[0036] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
