Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a farmland water conservancy inspection and patrol device. Background Technology

[0002] Floating debris such as human garbage, tree branches and leaves, and aquatic plants often appear in water bodies such as reservoirs and rivers. These floating debris will rot and deteriorate if soaked for a long time, causing water pollution and seriously affecting water quality. Therefore, it is necessary to clean up floating debris on the water surface in a timely manner.

[0003] There are two main methods for cleaning up floating debris on water surfaces. The first is to set up interception nets and dams at the entrances and exits of rivers and reservoirs. This method can only intercept floating debris when there is a water flow due to a height difference, and it cannot be used in calm waters such as lakes. Moreover, after interception, the floating debris cannot be transferred out of the water in time, which will still cause water pollution. The second method is to regularly dredge the debris by salvage boats. This method consumes a lot of manpower and resources, and can only be carried out when a large amount of floating debris is observed to have accumulated. It cannot be salvaged in time for small amounts of floating debris on the water surface, resulting in poor timeliness of cleaning and difficulty in ensuring water quality.

[0004] In summary, it is necessary to consider how to efficiently and promptly remove floating debris from the water surface in order to complete the water body cleaning operation and effectively salvage a small number of scattered floating debris. In view of this, we propose a farmland water conservancy inspection and patrol device. Summary of the Invention

The outer end of the embedded arc-shaped curved arm corresponds to the side wall of the rotating perforated plate. Above each of the vertical perforated plates is a cooperating component for cyclically driving the embedded arc-shaped curved arm to slide back and forth along the inside of the arc-shaped hollow shell and spraying disinfectant on the salvaged impurities.

[0010] Preferably, the vertical hole plate is fixedly connected below the lead screw sleeve and slides horizontally along the wall of the hollow annular cavity of the annular float; Bottom baffles and side baffles are respectively connected to the bottom end of the flip-over perforated plate and the horizontal inner side of the vertical perforated plate, and the bottom baffles and side baffles on both sides are arranged alternately.

[0011] Preferably, the collaborative component includes a collaborative hollow chamber fixedly installed inside the support base, and a processing piston is slidably installed in the inner cavity of the collaborative hollow chamber; The processing piston is connected to a traction arm at one end away from the support seat, and the traction arm slides horizontally and sealed through the cooperating hollow chamber and its outer end is fixedly connected to the lead screw sleeve.

[0012] Preferably, a flow pipe is provided between the arc-shaped hollow shell and the traction arm; As the processing piston moves along the end away from the support, the embedded arc-shaped curved arm presses the side wall of the flipping plate inward and flips it over.

[0013] Preferably, a hollow distribution box is installed at one end of the collaborative hollow chamber near the support base via a one-way drain valve pipe; The hollow distribution box has multiple horizontally connected diversion pipes installed at one end away from the support base, and multiple spray heads are installed on the diversion pipes.

Retrieval and disinfection operations can be completed continuously without additional operation, improving the overall efficiency of inspection work. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-6 The present invention will describe the above technical solution in detail through the following embodiments: Reference Figure 1 and Figure 2 This application provides a farmland water conservancy inspection and patrol device, including a drone body 1. The drone body 1 is equipped with a panoramic camera for inspecting and patrolling the water surface of water conservancy projects. The bottom of the drone body 1 is equipped with a water surface execution unit that can actively clean up floating garbage on the water surface. The water surface execution unit includes a lifting component and a capture component set on the lifting component for retrieval and cleaning of floating garbage in the water surface of water conservancy projects.

[0021] Specifically, the lifting assembly includes an outer protective shell 201 fixedly connected to the bottom of the UAV body 1. A bottom cover is sealed to the bottom opening of the outer protective shell 201. A take-up roller 202 is rotatably connected inside the outer protective shell 201 via a rotating shaft. The roller wall of the take-up roller 202 is provided with... Figure 3The position is limited by a conical groove. The take-up roller 202 has a take-up and release rope 204 wound around the outer periphery of the limited conical groove. The bottom of the bottom cover is fixedly connected to a limited guide cylinder 205. The free end of the take-up and release rope 204 passes through the limited guide cylinder 205 and is connected to an end block 206. A first servo reduction motor 203 is connected to the side wall of the outer protective shell 201. The output shaft of the first servo reduction motor 203 is connected to the end of the rotating shaft, and the first servo reduction motor 203 is used to drive the take-up roller 202 to rotate.

[0022] When performing water conservancy project inspection tasks, this invention can effectively prevent the drone from falling into the water when it is found to be floating garbage on the water surface. The drone body 1 is hovered at a safe position at least 5 meters above the water surface. Then, a lifting component lowers the capture component to the water surface, where it actively retrieves and cleans the floating garbage. The lifting component then retracts and lifts the captured component, and the drone body 1 flies to a garbage collection area to dump the retrieved garbage. This invention effectively avoids the drone body falling into the water when needing to be lowered close to the water surface to retrieve garbage, ensuring the stable progress of water conservancy project inspection work and bringing convenience to water surface inspection work.

[0023] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 The capture assembly includes an annular float 301 located below the end connecting block 206. An annular oil-absorbing felt 317 is connected to the bottom of the annular float 301. A bidirectional lead screw 305 is located above the annular float 301. Support seats 302 are rotatably connected to both ends of the bidirectional lead screw 305. A second servo reduction motor 303 is connected to the side wall of one of the support seats 302, and the output shaft of the second servo reduction motor 303 is connected to the end of the bidirectional lead screw 305. The two support seats 302 are respectively connected to the left and right sides of the annular float 301. A waterproof cover is provided around the outer periphery of the second servo reduction motor 303, and the waterproof cover is sealed to the side wall of the support seat 302. Two lead screw sleeves 306 are symmetrically threaded onto the bidirectional lead screw 305. An inverted U-shaped frame 304 is connected to the annular float 301, and the inverted U-shaped frame 304 is detachably installed at the bottom of the end connecting block 206.

[0024] In this embodiment, a flipping and retrieval unit is provided at the bottom of the screw sleeve 306, and a cooperative component is provided above the screw sleeve 306 to spray and disinfect the impurities floating on the water surface when the two flipping and retrieval units move in opposite directions and when the impurities retrieved by the two flipping and retrieval units fall.

[0025] Reference Figure 3The flipping and retrieval unit includes a vertical perforated plate 407 fixedly connected to the bottom of the corresponding lead screw sleeve 306. Multiple filter holes are evenly distributed through the vertical perforated plate 407. A flipping perforated plate 401 is rotatably connected to the bottom of the vertical perforated plate 407. Multiple filter holes are also evenly distributed through the flipping perforated plate 401. Multiple bottom baffles 402 are evenly connected to the bottom end of the flipping perforated plate 401. Multiple side baffles 403 are evenly connected from top to bottom on both the front and rear sides of the vertical perforated plate 407 near the other set of flipping and retrieval units. An arc-shaped hollow shell 404 is connected to the lower part of the orifice plate 407 away from the connected side baffle 403. An arc-shaped gas piston 405 is slidably connected to the inner cavity of the arc-shaped hollow shell 404. An embedded arc-shaped curved arm 406 is connected to the end of the arc-shaped gas piston 405, which is adapted to the inner cavity of the arc-shaped hollow shell 404 and slidably connected to the inner cavity of the arc-shaped hollow shell 404. The end of the embedded arc-shaped curved arm 406 away from the connected arc-shaped gas piston 405 is connected to the side wall of the flip orifice plate 401.

[0026] Because only a bidirectional lead screw 305 is provided, in order to achieve horizontal movement, the length between the front and rear ends of the vertical perforated plate 407 is the same as the length between the front and rear ends of the inner cavity of the annular float 301, and the vertical perforated plate 407 is slidably connected to the inner cavity of the annular float 301; in order not to hinder the collision during the process of retrieving impurities and to obtain a better retrieval surface, the side baffles 403 connected to the opposite faces of the two vertical perforated plates 407 are staggered, and the bottom baffles 402 connected to the opposite ends of the two flipping perforated plates 401 are staggered.

[0027] When floating debris is detected on the water surface, the first servo reduction motor 203 is started. Then, the free end of the reeling rope 204 continuously drives the capture component above the floating debris to move down. After the annular float 301 of the capture component floats on the water surface, the first servo reduction motor 203 is turned off and the second servo reduction motor 303 is started. Subsequently, the two flipping and retrieval units move towards each other. At the same time as the two flipping and retrieval units move towards each other, the screw sleeve 306 pulls the processing piston 312 and injects gas into the inner cavity of the arc-shaped hollow shell 404 through the inlet pipe 314.

[0028] When the end of the processing piston 312 abuts against the end of the cooperating hollow chamber 307, the flipping orifice plate 401 flips upward 90°. The bottom baffle 402 connected to the end of one flipping orifice plate 401 is staggered and inserted between the bottom baffle 402 connected to the end of the other flipping orifice plate 401. At the same time, the side baffle 403 connected to the side wall of one vertical orifice plate 407 is staggered and inserted between the side baffle 403 connected to the side wall of the other vertical orifice plate 407. This allows the floating garbage on the water surface to be contained within the structure formed by the two flipping and retrieval units, thereby quickly completing the retrieval and cleaning of the floating garbage on the water surface.

[0029] After the capture component has collected and cleaned up the floating garbage on the water surface, the first servo reduction motor 203 is restarted, causing the continuously winding roller 202 to pull the capture component containing the floating garbage upward and separate it from the water surface. When the top of the end connecting block 206 abuts against the bottom of the limiting guide cylinder 205, the first servo reduction motor 203 is turned off, and the UAV body 1 is controlled to fly to the garbage collection area and the second servo reduction motor 303 is controlled to reverse. Subsequently, the two flipping and retrieval units gradually move in opposite directions. During this process, the processing piston 312 continuously draws the gas inside the arc-shaped hollow shell 404 back into the cooperating hollow chamber 307 through the conveying pipe 314, causing the flipping perforated plate 401 to flip downward, so that the floating garbage can fall directly into the garbage collection area through the openings created by the two downward-flipping flipping perforated plates 401, which facilitates the dumping of garbage collected from the water surface by this invention.

[0030] Reference Figures 2 to 4 In this embodiment, the collaborative component includes a collaborative hollow chamber 307 connected at one end to the side wall of the corresponding support base 302. A processing piston 312 is slidably connected in the inner cavity of the collaborative hollow chamber 307. A traction arm 313 is connected to the end of the processing piston 312 connected to the support base 302 away from the end of the collaborative hollow chamber 307. A delivery pipe 314 is provided inside the traction arm 313. A hollow distribution box 316 is installed at the end of the collaborative hollow chamber 307 near the support base 302 through a one-way drain valve pipe 311. Multiple diversion pipes 315 are horizontally installed at the end of the hollow distribution box 316 away from the support base 302. Multiple spray heads are installed on the diversion pipes 315 for spraying disinfectant.

[0031] A liquid tank 308 is installed on the top of the coordinating hollow chamber 307. The liquid tank 308 has a filling port 309 on its top. The side of the coordinating hollow chamber 307 near the support base 302 is connected to the coordinating hollow chamber 307 through a one-way liquid inlet valve pipe 310.

[0032] The end of the traction arm 313 away from the connected processing piston 312 is sealed through the end of the cooperating hollow chamber 307 and connected to the end of the corresponding lead screw sleeve 306. One end of the conveying pipe 314 passes through the side wall of the traction arm 313 near the processing piston 312, and the other end passes into the interior of the corresponding lead screw sleeve 306 and the vertical hole plate 407 and is fixedly connected to the end of the arc-shaped hollow shell 404.

[0033] As the two tilting plates 401 gradually tilt downwards, the processing piston 312 continuously injects the disinfectant extracted from the cooperating hollow chamber 307 into the multiple diversion pipes 315 through the drain pipe. The disinfectant is then sprayed out from the spray nozzles on the diversion pipes 315, effectively disinfecting the tilting and retrieval unit and the retrieved waste, reducing the number of bacteria on the surface of the tilting and retrieval unit and the retrieved waste, and inhibiting secondary bacterial transmission. Simultaneously, as the two tilting and retrieval units move in opposite directions, the screw sleeve 306 pulls the processing piston 312. 12. Gas is injected into the inner cavity of the arc-shaped hollow shell 404 simultaneously through the inlet pipe 314. During this process, the processing piston 312 also simultaneously draws the disinfectant contained in the liquid tank 308 into the cooperating hollow chamber 307. This allows the present invention to simultaneously complete the automatic injection of disinfectant into the cooperating hollow chamber 307 while collecting and cleaning floating garbage on the water surface through the capture component. This makes it convenient for the present invention to continuously collect and clean floating garbage on the water surface during water conservancy project water surface inspection and patrol work.

[0034] The specific working steps of the farmland irrigation inspection and patrol device in this embodiment are as follows: S1. After controlling the drone body 1 to fly above the target water surface, hover the drone body 1 at a safe position at a height of at least 5 meters above the water surface. S2. When floating garbage is found on the water surface, the first servo reduction motor 203 is started. The first servo reduction motor 203 drives the winding roller 202 to rotate slowly, so that the free end of the winding rope 204 continuously drives the capture component above the floating garbage to move down. When the annular float 301 of the capture component floats on the water surface, the first servo reduction motor 203 is turned off, and the oil pollution on the water surface near the floating garbage is absorbed by the annular oil-absorbing felt 317. S3. Start the second servo reduction motor 303. After the second servo reduction motor 303 drives the bidirectional lead screw 305 to rotate, the two flipping and lifting units move towards each other. S4. While the two flipping and retrieval units are moving towards each other, the screw sleeve 306 pulls the processing piston 312 and injects gas into the inner cavity of the arc-shaped hollow shell 404 through the inlet pipe 314. At the same time, the processing piston 312 also draws the disinfectant contained in the liquid tank 308 into the cooperating hollow chamber 307. S5. When the end of the processing piston 312 abuts against the end of the cooperating hollow chamber 307, the flipping orifice plate 401 flips upward by 90°. The bottom baffle 402 connected to the end of one flipping orifice plate 401 is staggered and inserted between the bottom baffle 402 connected to the end of the other flipping orifice plate 401. At the same time, the side baffle 403 connected to the side wall of one vertical orifice plate 407 is staggered and inserted between the side baffle 403 connected to the side wall of the other vertical orifice plate 407. Thus, the floating garbage on the water surface can be contained inside the structure formed by the two flipping and retrieval units. S6. Restart the first servo reduction motor 203. The continuously winding roller 202 pulls the internal capture component that is scooping up the floating garbage on the water surface to move upward and separate from the water surface. When the top of the end connecting block 206 abuts against the bottom of the limiting guide tube 205, turn off the first servo reduction motor 203 and then control the drone body 1 to fly to the garbage collection area. S7. Control the second servo reduction motor 303 to reverse, and then the two flipping and retrieval units gradually move in opposite directions. During this process, the processing piston 312 continuously draws the gas inside the arc-shaped hollow shell 404 back into the cooperating hollow chamber 307 through the conveying pipe 314, so that the flipping orifice plate 401 flips downward, thus making it easier for floating garbage to fall directly into the garbage collection area through the openings created by the two downward-flipping orifice plates 401. S8. As the two rotating perforated plates 401 gradually rotate downwards, the processing piston 312 continuously injects the disinfectant extracted from the cooperating hollow chamber 307 into the multiple diversion pipes 315 through the drain pipe. Then, the disinfectant is sprayed out from the spray head on the diversion pipe 315 to achieve spray disinfection treatment on the rotating retrieval unit and the retrieved garbage.

[0035] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
