Abstract
Description
Technical Field
[0001] This utility model relates to the field of water surface garbage cleaning technology, and in particular to a water surface garbage cleaning drone. Background Technology
[0002] With the improvement of people's living standards, water pollution has become increasingly serious, and cleaning up surface debris has become an urgent problem to be solved. Traditional methods of cleaning up surface debris mainly rely on manual labor, which is not only inefficient but also labor-intensive and costly. Therefore, developing a drone capable of automatically identifying and cleaning up surface debris is of significant practical importance.
[0003] The existing patent publication number "CN215590999U" discloses a drone for garbage removal, including a drone body with four arms installed around the drone's fuselage. Each arm has a drive rotor installed at its top. The drone body has automatically folding legs installed on both sides of its bottom. A garbage collection bag, a garbage gripping mechanism, and a 360° smart camera are installed below the drone body. This utility model uses an electric push rod to extend, allowing an electric mechanical claw to contact the garbage. The electric mechanical claw retracts to grab the garbage. The position of the electric push rod and the electric mechanical claw can then be readjusted so that the electric mechanical claw extends into the collection bag and opens to drop the garbage into the collection bag, thus temporarily collecting the garbage through the collection bag.
[0004] The above description has the following problems: the surface of the garbage retrieved from the water is wet, and the water makes it easy for the garbage to stick to the electric robotic claw, making it difficult for the garbage to fall off during disposal; in addition, the wind force is strong during the flight of the drone. When the electric robotic arm that has grabbed the garbage extends into the garbage bag's disposal opening and opens, the garbage falls into the collection bag by its own weight. However, at the moment the electric robotic arm opens, lighter garbage will fly out of the garbage bag due to the strong wind, resulting in disposal errors and requiring a second retrieval, which reduces the efficiency of the operation. Utility Model Content
[0005] The purpose of this invention is to provide a surface garbage cleaning drone that solves the problem that garbage with water on its surface easily adheres to the electric mechanical gripper and is not easy to detach from the electric mechanical gripper.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a surface garbage cleaning drone, including a drone body, the bottom of which is provided with organic legs, a garbage grabbing mechanism and a garbage recognition camera, and also includes: A waste storage component is provided at the bottom of the drone body and opposite to the waste grabbing mechanism, and a waste disposal port is provided on the waste storage component; A waste collection auxiliary component is provided, which is used to cooperate with the waste grabbing mechanism to place the grabbed waste into the waste storage component. The waste collection auxiliary component includes a negative pressure exhaust fan disposed at the top of the waste storage component and an adsorption pipe connected to the air inlet of the negative pressure exhaust fan. The air inlet of the adsorption pipe is disposed inside the waste storage component and faces the waste disposal port. A filter screen is disposed inside the air inlet of the adsorption pipe.
[0007] Furthermore, the waste storage assembly includes a waste collection bin and a bin door. The side of the waste collection bin opposite to the waste grabbing mechanism is open. The bin door is openable and closable on the side of the waste collection bin with the opening. The waste disposal port is located at the top of the bin door. The air inlet of the adsorption tube is located inside the waste collection bin and faces the waste disposal port. The negative pressure exhaust fan is installed at the top of the exterior of the waste collection bin.
[0008] Furthermore, the bottom and circumferential sides of the garbage collection bin are provided with multiple water filter holes that communicate with its interior.
[0009] Furthermore, the garbage collection bin is equipped with a garbage storage mesh bag, the opening of which is open and detachably connected to the inner wall of the garbage collection bin, and the opening of the garbage storage mesh bag is lower than the garbage disposal port.
[0010] Furthermore, multiple hooks are provided along the circumference of the inner wall of the garbage collection bin, and the open end of the garbage collection bag is hung on the hooks.
[0011] Furthermore, the adsorption tube includes a first pipe, a second pipe, and a corrugated pipe. The filter screen is disposed inside the air inlet of the second pipe. The air outlet of the first pipe is connected to the air inlet of the negative pressure exhaust fan. The air inlet of the first pipe is fixed on the garbage collection bin and is connected to the interior of the garbage collection bin. The interior of the garbage collection bin is provided with a support plate for supporting the second pipe. The corrugated pipe is detachably connected between the first pipe and the second pipe.
[0012] Furthermore, the outer edge of the second pipe is provided with external threads, the air inlet end of the second pipe is threadedly connected to a limit plate, the support plate is provided with a through hole, the air outlet end of the second pipe slides through the through hole and connects to the corrugated pipe, and the outer diameter of the corrugated pipe is larger than the inner diameter of the through hole.
[0013] Furthermore, the air inlet of the adsorption tube is arranged in a funnel shape.
[0014] Furthermore, a moisture drying filter element is also provided inside the adsorption tube.
[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model provides a surface garbage cleaning drone, including a drone body with legs, a garbage grabbing mechanism, and a garbage recognition camera at the bottom. It also includes a garbage storage component located at the bottom of the drone body and opposite to the garbage grabbing mechanism, with a garbage disposal port. A garbage collection auxiliary component, used in conjunction with the garbage grabbing mechanism, places the grabbed garbage into the garbage storage component. The auxiliary component includes a negative pressure exhaust fan at the top of the garbage storage component and an adsorption pipe connected to the air inlet of the negative pressure exhaust fan. The air inlet of the adsorption pipe is located inside the garbage storage component and faces the garbage disposal port, with a filter screen inside the air inlet. The garbage collection auxiliary component can adsorb wet garbage that is difficult to detach from the electromechanical grippers, allowing the garbage to fall into the garbage storage component without adsorption, thus achieving garbage disposal and collection. Because the air inlet of the adsorption tube is located inside the waste storage component, and the distance between the air inlet of the adsorption tube and the waste disposal port is far, the waste is not easily affected by the wind when the drone is flying and a large wind is generated. Therefore, the waste will not fly out of the waste storage component, which can better dispose of the waste into the waste collection box, reduce the waste disposal error rate, and improve the operation efficiency.

[0021] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0022] refer to Figure 1 , Figure 2 and Figure 3This utility model provides a surface garbage cleaning drone, including a drone body 1. The bottom of the drone body 1 is provided with a body support 2, a garbage grabbing mechanism 3 and a garbage recognition camera 4. The garbage grabbing mechanism 3 includes an electric turntable 31 and a rotating arm 32. The electric turntable 31 is installed at the bottom of the drone body 1. A dual-axis rotary motor that drives the rotating arm 32 to rotate is installed at the bottom of the electric turntable 31. A support shaft 33 is installed at the bottom end of the rotating arm 32. A drive motor that drives the support shaft 33 to rotate is installed on the rotating arm 32. One end of the support shaft 33 is connected to an electric push rod 34. An electric mechanical claw 35 is installed at the telescopic end of the electric push rod 34.
[0023] refer to Figure 1 , Figure 2 and Figure 3 It also includes a waste storage component 5 and a waste collection auxiliary component 6. The waste storage component 5 is located at the bottom of the drone body 1 and is positioned opposite to the waste grabbing mechanism 3. The waste storage component 5 is provided with a waste disposal port 7. The waste collection auxiliary component 6 is used to cooperate with the waste grabbing mechanism 3 to place the grabbed waste into the waste storage component 5. The waste collection auxiliary component 6 includes a negative pressure exhaust fan 61 located at the top of the waste storage component 5 and an adsorption pipe 62 connected to the air inlet of the negative pressure exhaust fan 61. The air inlet of the adsorption pipe 62 is located inside the waste storage component 5 and faces the waste disposal port 7. A filter screen plate 63 is provided inside the air inlet of the adsorption pipe 62. The filter screen plate is a rigid plate. A moisture drying filter element 13 is also provided inside the adsorption pipe 62 (the moisture drying filter element can be a multi-layer filter screen, with adsorption activated carbon filled between adjacent filter screens). When adsorbing waste, the moisture drying filter element 13 dries the adsorbed moisture to prevent moisture from entering the negative pressure exhaust fan 61 and causing the negative pressure exhaust fan 61 to rust and corrode, resulting in damage. The air inlet of the adsorption tube 62 is flared, which increases the area of the air inlet and thus the adsorption area, allowing for better adsorption of the garbage grabbed by the garbage grabbing mechanism 3.
[0024] refer to Figure 1 , Figure 2 and Figure 3When this drone is working, it detects trash (such as bottles, bags, or tissues) on the water surface through the trash recognition camera 4. The trash grabbing mechanism 3 then uses the electric mechanical claw 35 to pick up the trash from the water surface and transport it to the trash disposal port 7. At this time, the negative pressure exhaust fan 61 works to draw in and absorb the trash grabbed by the electric mechanical claw, thus adsorbing the trash grabbed by the electric mechanical claw onto the air inlet end of the adsorption tube 62. Since a filter screen 63 is installed inside the air inlet end of the adsorption tube 62, the filter screen 63 acts as a barrier to block the trash, thus adsorbing the trash onto the air inlet end of the adsorption tube 62 and preventing the trash from entering the adsorption tube 62. When the negative pressure exhaust fan 61 is powered off and stops working, the trash falls into the trash collection bin by its own gravity without the adsorption force, thus realizing the picking and collection of trash. Therefore, by using the waste collection auxiliary component 6 in conjunction with the waste grabbing mechanism 3 to collect and dispose of waste, the air inlet of the adsorption pipe 62 is located inside the waste storage component 5, and the distance between the air inlet of the adsorption pipe 62 and the waste disposal port 7 is relatively far. Therefore, when the drone is flying and generates strong winds, the waste is not easily affected by the wind when it falls, and the waste will not fly out of the waste storage component 5. This allows the waste to be disposed of in the waste storage component 5 more effectively, reducing the waste disposal error rate and improving operational efficiency.
[0025] refer to Figure 1 , Figure 2 and Figure 3 The waste storage component 5 includes a waste collection bin 51 and a bin door 52. The side of the waste collection bin 51 opposite the waste grabbing mechanism 3 is open. The bin door 52 opens and closes on the side of the waste collection bin 51 with the opening. The waste disposal port 7 is located at the top of the bin door 52. The air inlet of the suction pipe 62 is located inside the waste collection bin 51 and faces the waste disposal port 7. The negative pressure exhaust fan 61 is installed on the top of the waste collection bin 51. This structure of the waste collection bin 51 can block wind, ensuring that the waste disposal and collection process is not affected by external wind, and reducing the waste disposal error rate. The waste collection bin 51 can be made of thinner sheet material (such as plastic sheet or aluminum sheet) to reduce the overall weight, thereby reducing the burden on the drone body 1 during flight.
[0026] refer to Figure 1 , Figure 2 and Figure 3 The bottom and circumferential sides of the garbage collection bin 51 are equipped with multiple water-filtering holes 8 that communicate with its interior. When garbage is placed into the garbage collection bin 51, the water on the garbage is filtered out through the water-filtering holes 8, achieving solid-liquid separation and preventing excessive water in the garbage collection bin 51 from increasing the burden on the drone body 1 during flight. In addition, the water-filtering holes 8 also reduce the wind resistance of the garbage collection bin 51, ensuring the stability of the drone body 1 during operation.
[0027] refer to Figure 1 , Figure 2 and Figure 3 The garbage collection bin 51 is equipped with a garbage storage mesh bag 9. The opening of the garbage storage mesh bag 9 is open and detachably connected to the inner wall of the garbage collection bin 51. The opening of the garbage storage mesh bag 9 is lower than the garbage disposal opening 7. Multiple hooks 10 are arranged circumferentially on the inner wall of the garbage collection bin 51, and the opening of the garbage bag is hung on the hooks 10. Garbage disposed of in the garbage collection bin 51 is collected and stored in the garbage storage mesh bag 9. When garbage is removed from the garbage collection bin 51, the garbage storage mesh bag 9 can be directly removed. The operation is simple, convenient, and quick, and the hooks 10 facilitate the hanging and retrieval of the garbage storage mesh bag 9.
[0028] refer to Figure 1 , Figure 2 and Figure 3 The adsorption tube 62 includes a first pipe 621, a second pipe 622, and a corrugated pipe 623. A filter screen 63 is disposed inside the air inlet of the second pipe 622. The air outlet of the first pipe 621 is connected to the air inlet of the negative pressure exhaust fan 61. The air inlet of the first pipe 621 is fixed to the garbage collection bin 51 and communicates with the interior of the garbage collection bin 51. A support plate 11 supporting the second pipe 622 is disposed inside the garbage collection bin 51. The corrugated pipe 623 is detachably connected between the first pipe 621 and the second pipe 622. When the negative pressure exhaust fan 61 is working, the vibration force is eliminated through the corrugated pipe 623, ensuring the stability of the drone body 1 during flight. The second pipe 622 can be set horizontally or inclined. When inclined, the air inlet of the second pipe 622 is tilted downward toward the garbage disposal port 7. This utility model is described with the second pipe 622 set horizontally as an example.
[0029] refer to Figure 1 , Figure 2 and Figure 3 The second pipe 622 has external threads on its outer edge. A limiting plate 12 is threadedly connected to the air inlet of the second pipe 622. A through hole is provided on the support plate 11. The air outlet of the second pipe 622 slides through the through hole and connects to a corrugated pipe 623. The outer diameter of the corrugated pipe 623 is larger than the inner diameter of the through hole. The corrugated pipe 623 is stretchable, thus the distance between the air inlet of the second pipe 622 and the garbage disposal port 7 can be adjusted according to actual conditions, enabling better adsorption of garbage. After adjustment, the limiting plate 12 is screwed onto the second pipe 622 to limit its position.
[0030] In summary, by using the waste collection auxiliary component 6 in conjunction with the waste grabbing mechanism 3 to collect and dispose of waste, the air inlet of the adsorption pipe 62 is located inside the waste storage component 5, and the distance between the air inlet of the adsorption pipe 62 and the waste disposal port 7 is relatively far. Therefore, when the drone is flying and generates strong winds, the waste is not easily affected by the wind when it falls, and the waste will not fly out of the waste storage component 5. This allows the waste to be disposed of more effectively into the waste collection bin 51, reducing the waste disposal error rate and improving operational efficiency.
[0031] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
