Description

Technical Field

[0001] The utility model relates to the field of water body maintenance, and in particular to a drone used for collecting floating objects on the water surface. Background Art

[0002] In recent years, the work of cleaning up floating garbage on the water surface still faces many challenges.

[0003] First, the manual collection of floating garbage on the water surface has significant limitations. It is not only time-consuming and labor-intensive, but also inefficient and accompanied by high safety risks. In some waters, due to complex terrain or water depth restrictions, it is difficult for ships to navigate or reach, which further increases the difficulty of cleaning work; secondly, even if ships are used for garbage collection, there are problems of slow speed and incomplete cleaning. Ships collect garbage on the river surface with difficulty, but due to the slow speed, it is difficult to achieve efficient and comprehensive cleaning; in addition, although salvage ships can be used to clean up floating garbage on the water surface in a timely manner, this method works better in waters where garbage is more concentrated. However, due to the limitation of the water surface, some waters cannot be reached by ships, the navigation speed is slow, and it takes a long time, which makes it difficult to clean up garbage thoroughly; some people have tried to use ocean currents to clean up floating garbage on the water surface, but this method is costly and cannot clean up garbage in a timely and effective manner.

[0004] In the face of these challenges, the application of drone technology has gradually shown its potential. Drones are fast and flexible, but under the current technical conditions, they are not ideal for cleaning up floating garbage on the water surface. In order to solve the significant limitations of the manual method of collecting floating garbage on the water surface, which not only consumes a lot of time and labor, but is also inefficient and accompanied by high safety risks, it is necessary to improve the structure of drones to better meet the needs of cleaning up floating garbage on the water surface. Utility Model Content

[0005] The utility model aims to provide a drone for collecting floating objects on the water surface, so as to solve the technical problem that the method of manually collecting floating garbage on the water surface has significant limitations, which not only consumes a lot of time and labor, but also is inefficient and is accompanied by high safety risks.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] The utility model discloses a drone for collecting floating objects on the water surface, which can fly close to the water surface at low altitude. The drone comprises a fuselage, and an image acquisition device and an image transmission module are fixed on the top of the fuselage. The image acquisition device and the image transmission module are electrically connected. The acquisition end of the image acquisition device faces the forward direction of the drone and is used to acquire the water surface image in the area in front of the fuselage during flight.

[0008] The image transmission module is fixed on the top of the fuselage, and is used to receive the image captured by the image acquisition device and transmit the image to the background remote control device;

[0009] A flight control system is also fixed on the top of the fuselage, which is used to control the flight direction or height of the drone according to the flight instructions from the background remote control device;

[0010] A mobile power source is also fixed at the bottom of the fuselage to provide a power source for the drone;

[0011] A water surface cleaning component is also fixed to the bottom of the fuselage for collecting floating objects on the water surface during flight.

[0012] The working principle of this scheme is: the drone for collecting floating objects on the water surface disclosed in this scheme can capture and transmit the image in the water surface area in front of the flight in real time through the image acquisition device and image transmission module installed on its top, and transmit it to the background remote control device for display. The operator can view the picture of the water surface area in front of the flight through the background remote control device, and when seeing floating objects that need to be collected on the water surface, the operator can operate the background remote control device to send operating instructions to the flight control system of the drone, instructing the drone to perform low-altitude near-water flight and floating object collection operations. The water surface cleaning component at the bottom of the drone is responsible for collecting floating objects on the water surface during flight. The entire flight system has the characteristics of remote operation, efficient monitoring, precise positioning, low-altitude flight capability, flexible maneuverability, environmental protection and energy saving, and rapid response, which effectively improves the efficiency and effect of collecting floating objects on the water surface, while reducing the risk and cost of manual operation.

[0013] Preferably, the image acquisition device adopts a miniature camera, and the shooting angle of the miniature camera is greater than 40°.

[0014] Preferably, the camera angle of the micro camera is 40° to 60°, which is closer to the natural field of vision of the human eye and is usually provided by a focal length of 35mm to 50mm.

[0015] Preferably, the camera angle of the micro camera is 65° to 90°, and the camera lens within this camera angle range is an ultra-wide-angle lens, which can provide a wider field of view.

[0016] Preferably, the camera angle of the micro camera is 90° to 110°, and the camera lens within this camera angle range is an extremely wide-angle lens, which can provide a wider field of view than an ultra-wide-angle lens.

[0017] As one of the implementation methods of the structure of the drone itself, the two sides of the fuselage are respectively provided with side wings, the tail of the fuselage is obliquely extended upward away from the fuselage with a tail wing, and the tail wing is provided with ailerons extending laterally, and the ailerons are electrically connected to the mobile power source and can swing up and down to control the pitch of the aircraft;

[0018] A vertically extending rudder is arranged at the rear of the tail wing away from the fuselage, and the rudder is electrically connected to the mobile power source and can swing left and right to control the steering of the aircraft;

[0019] A horizontal frame is fixed at the bottom center of the front part of the fuselage, and a first motor and a second motor are fixed at both ends of the horizontal frame respectively; a first propeller is fixed at the output end of the first motor, and the first motor can be electrically driven to rotate the output end, thereby driving the first propeller to rotate;

[0020] A second propeller is fixed to the output end of the second motor, and the second motor can be electrically driven to rotate the output end, thereby driving the second propeller to rotate;

[0021] The first propeller and the second propeller are both oriented toward the tail wing, and their rotation directions are opposite; making the first propeller and the second propeller rotate in opposite directions respectively helps to balance the torque applied to the aircraft and reduce the yaw or rotation tendency of the aircraft during flight.

[0022] The UAV designed by the utility model is different from the traditional push-type propeller layout. The traditional push-type propeller layout usually installs the propeller on the wing or fuselage, facing the nose direction to pull the aircraft forward. The UAV designed by the utility model adopts a pull-in propeller configuration, that is, when the UAV needs to move forward, looking from the tail to the nose, the first propeller rotates clockwise and the second propeller needs to rotate counterclockwise; the pull-in propeller configuration can also reduce the impact of the propeller slipstream on the tail structure of the aircraft, which helps to improve the propulsion efficiency.

[0023] Preferably, a third motor is fixed on the tail wing, a third propeller is fixed to the output end of the third motor, and the third motor can be electrically driven to rotate the output end, thereby driving the third propeller to rotate.

[0024] The third propeller can serve as auxiliary thrust to help the aircraft obtain additional thrust in specific flight phases (such as take-off, climb or slow flight); the rotation direction of the third propeller is consistent with the direction in which the main thrust is generated, that is, toward the nose of the aircraft to provide forward thrust.

[0025] As one of the implementation methods of the water surface cleaning component, the water surface cleaning component includes a filter barrel, which is suspended at the bottom of the fuselage; the filter barrel is an overall cylindrical structure, one end of the filter barrel has an opening, the opening is a water inlet, and the other end opposite to the opening is fixed with a mesh plate, the mesh plate is a porous structure, and the mesh plate is a circular structure; when the drone is flying, the upper part of the filter barrel along the direction in which the cylindrical structure extends floats on the water surface, and the lower part is located in the water body, the water flows into the filter barrel from the opening, flows out from the mesh plate, and floating objects on the water surface remain in the filter barrel.

[0026] As another implementation method of the water surface cleaning component, the water surface cleaning component includes a filter screen, the peripheral side of the filter screen is fixed on a frame, the frame is formed by four rods connected end to end to form a square frame structure, the center of the frame is a water inlet, one of the rods of the frame and another rod opposite to it are respectively suspended at the rear and front sides of the bottom of the fuselage; the frame is inclined in the water body, and the upper part of the frame is exposed above the water surface, and the lower part of the frame is located in the water body. When the UAV is flying, the water surface flows into the filter screen from the water inlet of the frame and flows out from the other side of the filter screen, and floating objects on the water surface remain in the filter screen.

[0027] As a preferred solution for the UAV, an electronic weighing scale is installed between the bottom of the fuselage and the water surface cleaning component. The electronic weighing scale is electrically connected to the flight control system and is used to weigh the water surface cleaning component.

[0028] If the total weight of the surface cleaning components reaches 70% to 80% of the rated load of the drone, the flight control system will control it to return.

[0029] The technical solution of the utility model has the following beneficial effects:

[0030] 1. The drone for collecting floating objects on the water surface disclosed by the utility model has a water surface cleaning component at the bottom of the drone that can collect floating objects on the water surface in a timely manner during flight, which can solve the significant limitations of the method of manually collecting floating garbage on the water surface, reduce cleaning time, save labor, significantly reduce the labor intensity of manual garbage collection, and at the same time improve the efficiency of water surface garbage collection, while reducing the risk and cost of manual operations.

[0031] 2. The utility model of the UAV for collecting floating objects on the water surface utilizes its low-altitude flight capability and strong adaptability to various environmental conditions to collect surface garbage quickly and timely, which helps to deal with the problem of surface garbage pollution more efficiently.

[0032] 3. Through technological innovation and structural optimization, the utility model of the UAV for collecting floating objects on the water surface has broad application prospects in cleaning floating garbage on the water surface. Its efficient ability to clean floating garbage on the water surface is expected to play a more important role in future environmental protection work. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the utility model of a drone for collecting floating objects on the water surface in conjunction with the accompanying drawings.

[0039] The utility model can be applied to the remote control and unmanned collection of garbage floating in oceans, lakes and rivers, solving the technical problem that the method of manually collecting garbage floating on the water surface has significant limitations, which not only consumes a lot of time and labor, but is also inefficient and accompanied by high safety risks.

[0040] See also Figure 1 to Figure 2Based on the technical problems solved above, the utility model discloses a drone for collecting floating objects on the water surface, which can fly at a low altitude close to the water surface 700. The drone 100 includes a fuselage 101, and an image acquisition device 200 and an image transmission module 300 are fixed on the top of the fuselage 101. The image acquisition device 200 and the image transmission module 300 are electrically connected. The acquisition end of the image acquisition device 200 faces the forward direction of the drone 100, and is used to collect the water surface image in the area in front of the fuselage 101.

[0041] The image transmission module 300 is fixed on the top of the fuselage 101, and is used to receive the image captured by the image acquisition device 200, and transmit the image to the background remote control device, and the background remote control device displays the image;

[0042] A flight control system 400 is also fixed on the top of the fuselage 101, which is used to receive flight instructions from a background remote control device and control the flight direction or height of the drone 100 according to the flight instructions from the background remote control device;

[0043] A mobile power source 113 is also fixed to the bottom of the fuselage 101 to provide a power source for the drone 100;

[0044] A water surface cleaning assembly 600 is also fixed to the bottom of the fuselage 101 for collecting floating objects on the water surface during flight.

[0045] The working principle of this scheme is: the drone for collecting floating objects on the water surface disclosed in this scheme can capture and transmit the image in the water surface 700 area in front of the flight in real time through the image acquisition device 200 and the image transmission module 300 installed on the top thereof, and transmit it to the background remote control device for display. The operator can view the picture of the water surface area in front of the flight through the background remote control device, and when seeing floating objects that need to be collected on the water surface, the operator can operate the background remote control device to send an operation instruction to the flight control system 400 of the drone 100, instructing the drone 100 to perform low-altitude near-water flight and floating object collection operations. The water surface cleaning component 600 at the bottom of the drone 100 is responsible for collecting floating objects on the water surface during the flight. The entire flight system has the characteristics of remote operation, efficient monitoring, precise positioning, low-altitude flight capability, flexible maneuverability, environmental protection and energy saving, and rapid response, which effectively improves the efficiency and effect of collecting floating objects on the water surface, while reducing the risk and cost of manual operation.

[0046] Preferably, the image acquisition device 200 uses a miniature camera, and the shooting angle of the miniature camera is greater than 40°.

[0047] Preferably, the camera angle of the micro camera is 40° to 60°, which is closer to the natural field of vision of the human eye and is usually provided by a focal length of 35mm to 50mm.

[0048] Preferably, the camera angle of the micro camera is 65° to 90°, and the camera lens within this camera angle range is an ultra-wide-angle lens, which can provide a wider field of view.

[0049] Preferably, the camera angle of the micro camera is 90° to 110°, and the camera lens within this camera angle range is an extremely wide-angle lens, which can provide a wider field of view than an ultra-wide-angle lens.

[0050] The use of a wide-angle lens can have a wider field of view, which can improve image acquisition efficiency, reduce the number of drone flights by 100, save time and flight costs; in addition, the images collected by the wide-angle lens contain more visual information, which helps to provide more data points, increase the data density of surface floating object detection, and provide richer image acquisition data for the background remote control device; because it can provide a wider reference background, it helps to better locate the exact position of surface floating objects. For example, the images collected by the wide-angle lens are used to create a panoramic image of a 700-degree area on the water surface, and a large-scale detailed view is generated through image stitching technology; after image acquisition, the large-scale image field of view is also more conducive to the remote operator to observe surface floating objects, which helps to more timely discover floating object targets that need to be collected.

[0051] In specific implementation, the flight control system 400 uses a finished product that can be directly purchased on the market. The flight control system has integrated functions. The flight control system 400 needs to receive signals sent by the background remote control device, and convert the transmitted signals into specific flight actions of the drone 100 after parsing; it is also necessary to adjust the power system of the drone, including the speed and direction of the motor, according to the instructions of the flight control module to achieve precise speed and direction control; through sensors such as gyroscopes and accelerometers, the attitude changes of the drone are monitored in real time, and by adjusting the motor output, the external disturbance is quickly responded to to maintain the stable flight of the drone; the flight control system also integrates GPS or other navigation technologies to determine the precise position and flight path of the drone, ensuring that the drone can efficiently perform tasks according to the established cleaning route; An emergency processing module that stores a preset flight control program can also be designed in the flight control system. In the event of an emergency or signal loss, the emergency processing module can automatically take over the control of the drone according to the preset flight control program, execute the safe return or landing procedure, and ensure the safety of the drone and the surrounding environment; the flight control system can also provide real-time feedback of the drone's status information, including flight data, battery power, cleaning progress, etc. to the background remote control device, so that the operator can understand the real-time status of the drone and make corresponding adjustments; in addition, the flight control system is also provided with a power management unit, which can provide stable and continuous power to each module, and has power monitoring and low-power warning functions, so as to ensure that the drone can return and ensure the safety of the drone when the cleaning time of floating objects on the water surface is too long and the endurance is insufficient.

[0052] In the specific implementation, in order to facilitate the flight control and camera control of the drone, the background remote control device is in the form of a handheld wireless remote control, and each functional module is integrated inside the handheld wireless remote control. Each functional module can be purchased on the market as a finished product with each corresponding function.

[0053] Next, the main functional modules in the handheld wireless remote control are described, including:

[0054] Transmitter module: This module is equipped with an operation panel that enables the operator to directly input commands. These commands are transmitted to the microcontroller through the transmitter module. The operation panel includes operating keys such as joysticks, buttons, switches, etc.

[0055] Microcontroller: The input end of the microcontroller is connected to the output end of the transmitter module, and the microcontroller is used to analyze the user input of the transmitter module and convert it into a UAV flight control signal;

[0056] Wireless communication module: The input end of the wireless communication module is connected to the output end of the microcontroller. The wireless communication module is used to convert the signal of the microcontroller into a wireless signal and transmit it to the flight control system set on the UAV, ensuring the wireless long-distance transmission of the control signal;

[0057] Flight mode control module: provides a variety of flight modes such as manual, automatic, and return, allowing operators to flexibly select the flight status of the drone according to actual conditions and mission requirements;

[0058] Camera control module: allows operators to make detailed adjustments to the image acquisition device, including zoom, focus and shooting mode, to capture clearer and more accurate water surface images;

[0059] Image display module: displays the images sent back by the drone, so that the operator can observe the images in front of the drone, and provide the operator with clear visual information of the target of cleaning floating objects on the water surface;

[0060] Rechargeable power supply and power management module: Provides stable and continuous power supply for all modules, ensuring the stable operation of the entire handheld wireless remote control.

[0061] Then, for each of the above functional modules, the working process of the drone 100 using this solution to clean up floating objects on the water surface is: first, control the drone 100 to fly at a low altitude, conduct a full-scale scan of the water surface area to be cleaned, and display the overall situation of the water surface to be cleaned in the background remote control device. The operator observes the picture of the area in front of the drone through the background remote control device to determine whether there are floating objects on the water surface that need to be cleaned, and when necessary, operate the background remote control device to send operating instructions to the flight control system of the drone, instructing the drone to fly at a low altitude near the water surface and collect floating objects, so as to clean up floating objects on the water surface in a targeted manner.

[0062] As one of the implementation methods of the structure of the drone 100 itself, please refer to Figure 1, the two sides of the fuselage 101 are respectively provided with side wings 102, the tail of the fuselage 101 is obliquely extended upward away from the fuselage 101 with a tail wing, the tail wing is provided with a laterally extending aileron 103, the aileron 103 is electrically connected to the mobile power supply 113, can swing up and down, and is used to control the pitch of the aircraft; the tail wing is provided with a vertically extending rudder 104 at the rear away from the fuselage 101, the rudder 104 is electrically connected to the mobile power supply 113, can swing left and right, and is used to control the steering of the aircraft; a cross frame 105 is fixed at the bottom center of the front part of the fuselage 101, and the two ends of the cross frame 105 are respectively fixed with a first motor 106 and a second motor 108; a first propeller 107 is fixed to the output end of the first motor 106, and the first motor 106 can be electrically driven to rotate the output end, thereby driving the first propeller 107 to rotate; a second propeller 109 is fixed to the output end of the second motor 108, and the second motor 108 can be electrically driven to rotate the output end, thereby driving the second propeller 109 to rotate; the first propeller 107 and the second propeller 109 are both facing the direction of the tail wing, and the rotation directions of the two are opposite; making the first propeller 107 and the second propeller 109 rotate in opposite directions respectively helps to balance the torque exerted on the aircraft and reduce the yaw or rotation tendency of the aircraft during flight.

[0063] The drone 100 designed in the utility model is different from the traditional push-type propeller layout, which usually installs the propeller on the wing or fuselage 101, facing the nose direction to pull the aircraft forward. The drone 100 designed in the utility model adopts a pull-in propeller configuration, that is, when the drone 100 needs to move forward, looking from the tail to the nose, the first propeller 107 rotates clockwise and the second propeller 109 needs to rotate counterclockwise; the pull-in propeller configuration can also reduce the impact of the propeller slipstream on the tail structure of the aircraft, which helps to improve the propulsion efficiency.

[0064] The drone 100 used in this solution can utilize the ground effect so that the aircraft can obtain better controllability and efficiency when flying at low altitudes. Specifically, the ground effect is also called the "air cushion effect", which means that when the aircraft flies close to the ground or water surface 700, due to the influence of the ground or water surface 700 on the air flow, the lift of the aircraft will be enhanced and the resistance will be reduced, which enables the aircraft to obtain better controllability and efficiency when flying at low altitudes.

[0065] Specifically, by adjusting the angle of the aileron 103, the lift of the tail can be increased or decreased, thereby controlling the pitch movement of the aircraft. During the take-off and landing of the aircraft, the tail wing is mainly responsible for maintaining the longitudinal balance of the aircraft and controlling the pitch attitude of the aircraft; the left and right swinging of the rudder 104 can control the yaw movement of the aircraft, that is, left and right steering; the two work together to ensure that the aircraft can fly stably and accurately respond to the operator's manipulation.

[0066] As a preference, see Figure 1 The tail wing is also fixed with a third motor 110, and the output end of the third motor 110 is fixed with a third propeller 111. The third motor 110 can be electrically driven to rotate the output end, thereby driving the third propeller 111 to rotate. The third propeller 111 can be used as an auxiliary thrust to help the aircraft obtain additional thrust in a specific flight phase (such as take-off, climb or slow flight); the rotation direction of the third propeller 111 is consistent with the direction of the main thrust, that is, toward the nose direction, to provide forward thrust.

[0067] Specifically, the center of the cross frame 105 is fixed at the bottom center of the front part of the fuselage 101 to keep the cross frame 105 symmetrically fixed.

[0068] Specifically, a landing gear 112 is fixed to the bottom of the fuselage 101 to assist in landing and taking off on the fuselage 101 and also to play a buffering role.

[0069] Specifically, the fuselage 101 is designed to be streamlined, which can reduce air resistance and improve flight efficiency.

[0070] Specifically, the cross section of the fuselage 101 is circular, elliptical or polygonal.

[0071] Specifically, the ratio of the length of the fuselage 101 to the maximum width of the cross section is in the range of 5:1 to 10:1.

[0072] Specifically, the nose of the fuselage 101 is designed to be a frustum in shape to optimize aerodynamic performance.

[0073] Specifically, the fuselage 101 structure is a single-shell structure, a multi-shell structure or a semi-rigid shell structure.

[0074] As one implementation of the water surface cleaning assembly 600, please refer to Figure 2The water surface cleaning component 600 includes a filter barrel 601, which is suspended at the bottom of the fuselage 101; the filter barrel 601 is a cylindrical structure as a whole, and one end of the filter barrel 601 has an opening 605, and the opening 605 is a water inlet. A mesh plate 604 is fixed to the other end opposite to the opening 605, and the mesh plate is a porous structure, and the mesh plate 604 is a circular structure; when the drone 100 is flying, the upper part of the filter barrel 601 along the direction in which the cylindrical structure extends floats on the water surface 700, and the lower part is located in the water body. The water flows into the filter barrel 601 from the opening 605 and flows out from the mesh plate 604, and floating objects on the water surface remain in the filter barrel 601.

[0075] Specifically, the mesh plate is a hard plate with a pore size ranging from 0.5 to 5 cm.

[0076] Specifically, two lifting ears 602 are symmetrically fixed to the upper part of the outer periphery of the filter barrel 601 . The lifting ears 602 are provided with openings for tying one end of a lifting rope 603 . The other end of the lifting rope 603 is fixed to the bottom of the fuselage 101 .

[0077] As another implementation of the water surface cleaning assembly 600, please refer to Figure 3 The water surface cleaning component 600 includes a filter 606, the peripheral side of the filter 606 is fixed on a frame 607, the frame 607 is surrounded by four rods connected end to end to form a square frame structure, the center of the frame 607 is a water inlet, one of the rods of the frame 607 and another rod arranged opposite to it are respectively suspended at the rear and front sides of the bottom of the fuselage 101; the frame 607 is tilted in the water body, and the upper part of the frame 607 is exposed to the water surface 700, and the lower part of the frame 607 is located in the water body. When the drone 100 is flying, the water surface 700 flows into the filter 606 from the water inlet of the frame 607 and flows out from the other side of the filter 606, and floating objects on the water surface remain in the filter 606.

[0078] Specifically, the filter screen is a soft structure, and its mesh aperture ranges from 0.5 to 5 cm.

[0079] Specifically, the frame 607 is formed by connecting the first rod, the second rod, the third rod and the fourth rod in sequence end to end. The first rod and the third rod are arranged opposite to each other. One end of a front sling 608 is fixed to the first rod, and one end of a rear sling 609 is fixed to the third rod. The other end of the front sling 608 is fixed to the front side of the bottom of the fuselage 101, and the other end of the rear sling 609 is fixed to the rear side of the bottom of the fuselage 101; and the length of the front sling 608 is longer than that of the rear sling 609, so that the frame 607 structure is tilted in the water, with the forward direction of the drone 100 as the front, and the third rod is located behind the first rod.

[0080] As a preferred solution for the drone 100 , an electronic weighing scale is installed between the bottom of the fuselage 101 and the water surface cleaning component 600 . The electronic weighing scale is electrically connected to the flight control system 400 and is used to weigh the water surface cleaning component 600 .

[0081] If the total weight of the water surface cleaning assembly 600 reaches 70% to 80% of the rated load of the UAV 100, the flight control system 400 controls the UAV 100 to return.

[0082] The use of a drone for collecting floating objects on the water surface disclosed by the utility model has the following technical effects: the drone for collecting floating objects on the water surface disclosed by the utility model is intended to significantly reduce the labor intensity of manual garbage collection and improve the efficiency of garbage collection on the water surface. The drone for collecting floating objects on the water surface can collect garbage on the water surface quickly and timely by utilizing its low-altitude flight capability and strong adaptability to various environmental conditions, which helps to deal with the problem of garbage pollution on the water surface more efficiently. In addition, the drone for collecting floating objects on the water surface combines advanced image acquisition and transmission technology, as well as remote flight control, which not only improves the response speed of the operation, but also reduces the safety risks caused by manual operation. Through technological innovation and structural optimization, the drone for collecting floating objects on the water surface has broad application prospects in cleaning floating garbage on the water surface.
