Technical Field

[0001] This utility model relates to the field of sewage sampling technology, specifically to a drone for river patrol that facilitates sewage sampling. Background Technology

[0002] With increasing environmental awareness, the monitoring and protection of river water quality has become increasingly important. Wastewater sampling is a crucial step in obtaining water quality information during river patrols. An existing patent (CN210027915U) describes a drone for river patrols that facilitates wastewater sampling. The drone includes a main body with a wing fixedly connected to one side. A protective box is fixedly connected to one end of the wing, and a support block is fixedly connected to the inner bottom wall of the protective box. A first motor is fixedly connected to one side of the support block, and the output shaft of the first motor is fixedly connected to a first connecting shaft via a coupling. A rotating fan blade is fixedly connected to the outer wall of the first connecting shaft, and a rotating shaft is fixedly connected to one side of the drone main body. This wastewater-sampling drone for river patrols, through its hydraulic cylinder, hydraulic rod, connecting plate, auxiliary box, top block, servo motor, rotating disk, connecting block, and sampling tube, allows for more convenient and faster wastewater sampling, solving the problem of conventional drones being inconvenient for wastewater sampling, thereby improving work efficiency and meeting people's needs.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: when using them, existing drones, when sampling rivers, lack an effective sealing structure after sampling, which makes it easy for sewage in the sampling bucket to leak out as the drone flies after sampling, thus having limitations. Therefore, we propose a drone for river patrol that facilitates sewage sampling to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a drone for river patrol that facilitates sewage sampling. It solves the problem that existing technologies lack an effective sealing structure after sampling, which easily leads to sewage leakage from the sampling bucket as the drone flies after sampling, thus limiting their effectiveness.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a drone for river patrol that facilitates sewage sampling, comprising a drone body structure, wherein a plunger mechanism is installed on the bottom surface of the body structure, and the main body of the plunger mechanism is made of rubber.

[0006] A magnetic suction assembly is fixedly connected to the outside of the plunger mechanism. The magnetic suction assembly is a ring electromagnet structure. A support mechanism is fixedly connected to the bottom surface of the body mechanism. Each pair of longitudinally adjacent support mechanisms forms a group.

[0007] Both sets of support mechanisms are equipped with servo motors on their outer sides. A winding wheel is installed on the output shaft of the servo motor. A guide wheel for guiding the traction rope is also installed at the bottom of the machine body mechanism. The traction rope is wound around the outer side of the traction rope.

[0008] A hanging ring A is fixedly connected to the bottom end of the traction rope. A hanging ring B is installed on the outside of the hanging ring A. A sampling bucket is fixedly connected to the inside of the hanging ring B. A counterweight is fixedly connected to the bottom end of the sampling bucket.

[0009] Preferably, the front end of the body mechanism has a groove, and a gimbal module is rotatably connected inside the groove.

[0010] Preferably, a camera is fixedly connected to the front end of the gimbal module, and a support arm assembly is fixedly connected to the outer side of the body mechanism.

[0011] Preferably, the main body of the support arm assembly is inclined, and there are four support arm assemblies, which are respectively fixedly connected to the four corners of the outer side of the machine body.

[0012] Preferably, the arm assembly has a driver for a motor structure installed inside.

[0013] Preferably, a blade assembly is mounted on the top output shaft of the driver.

[0014] Preferably, the outer side of the body structure is fixedly connected with an inclined support leg assembly. There are four support leg assemblies in total, with each pair of longitudinally adjacent support leg assemblies forming a group. Support assemblies are fixedly connected to the outer side of each group of support leg assemblies.

[0015] Beneficial effects

[0016] This invention provides a drone for river patrol that facilitates wastewater sampling. Compared with existing technologies, it has the following advantages:

[0017] This unmanned aerial vehicle (UAV) for river patrol, which facilitates sewage sampling, uses a rubber plug mechanism at the bottom of the body, along with a magnetic suction component with an outer ring electromagnet structure. After the sampling bucket has finished sampling and is lifted back, the magnetic suction component is energized to attract the sampling bucket, and the plug mechanism blocks the opening of the sampling bucket, forming a reliable closed structure. This greatly reduces the possibility of sewage leakage during transportation, ensures the integrity and accuracy of sampling, and avoids secondary pollution to the environment.

[0018] This unmanned aerial vehicle (UAV) for river patrol, which facilitates wastewater sampling, utilizes tilted outriggers at the four corners of the fuselage, along with internal actuators and top-mounted blades, to provide stable lift, ensuring flight stability and maneuverability. The combination of a gimbal module and camera allows operators to comprehensively observe the river conditions and promptly identify problems. For takeoff and landing, the tilted outriggers and external support components enhance the stability of the UAV when parked. These designs improve the overall performance of the UAV, making it more efficient and reliable in river patrol and wastewater sampling, reducing operational difficulty, and increasing work efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6 This utility model provides a technical solution: a drone for river patrol that facilitates sewage sampling, including a drone body structure 1, a plunger mechanism 2 installed on the bottom surface of the body structure 1, and the main body of the plunger mechanism 2 being made of rubber.

[0028] A magnetic suction component 201 is fixedly connected to the outside of the plunger mechanism 2. The magnetic suction component 201 is a ring electromagnet structure. A support mechanism 3 is fixedly connected to the bottom surface of the body mechanism 1. Each pair of longitudinally adjacent support mechanisms 3 forms a group.

[0029] Servo motors 301 are installed on the outer side of both sets of support mechanisms 3. A winding wheel 3011 is installed on the output shaft of the servo motor 301. A guide wheel for guiding the traction rope 3012 is also installed at the bottom of the body mechanism 1. The traction rope 3012 is wound around the outer side of the traction rope 3012.

[0030] A hanging ring A3013 is fixedly connected to the bottom end of the traction rope 3012. A hanging ring B3014 is installed on the outside of the hanging ring A3013. A sampling bucket 3015 is fixedly connected to the inside of the hanging ring B3014. A counterweight 3016 is fixedly connected to the bottom end of the sampling bucket 3015.

[0031] By installing a rubber plunger mechanism 2 and its outer magnetic suction component 201 at the bottom of the body mechanism 1, and in conjunction with the support mechanism 3, servo motor 301, winding wheel 3011, traction rope 3012, hanging ring A 3013, hanging ring B 3014, sampling bucket 3015 and counterweight 3016, the sampling bucket 3015 can be stably suspended and wastewater sampling can be achieved. The magnetic suction component 201 can adsorb and position the sampling bucket 3015, reducing the risk of wastewater leakage.

[0032] See Figures 1-5 The front end of the body mechanism 1 has a groove, and the gimbal module 101 is rotatably connected inside the groove.

[0033] By rotating and connecting the gimbal module 101 in the groove at the front end of the body mechanism 1, the gimbal module 101 can rotate flexibly, which makes it easy to adjust the shooting angle of the camera 1011 installed at its front end, which is beneficial for comprehensive observation during river patrol.

[0034] See Figures 3-6 A camera 1011 is fixedly connected to the front end of the gimbal module 101, and a support arm assembly 1012 is fixedly connected to the outside of the body mechanism 1.

[0035] The camera 1011 is fixed at the front of the gimbal module 101 to capture and record the river conditions. The support arm assembly 1012 is connected to the outside of the body structure 1 to provide support for the subsequent installation of the driver 1013 and the blade assembly 1014, ensuring the flight of the drone.

[0036] See Figures 1-2 The main body of the support arm assembly 1012 is inclined. There are four support arm assemblies 1012, which are fixedly connected to the four corners of the outer side of the body mechanism 1.

[0037] By using the outrigger assemblies 1012, which are tilted in four places and located at the four corners of the outer side of the body structure 1, better aerodynamic performance can be provided for the UAV, ensuring flight stability and maneuverability.

[0038] See Figures 5-6 The arm assembly 1012 has a motor-driven driver 1013 installed inside;

[0039] The driver 1013 installed inside the boom assembly 1012 provides power to the blade assembly 1014, causing the blade assembly 1014 to rotate and generate lift, thus driving the drone to fly.

[0040] See Figures 1-2 A blade assembly 1014 is mounted on the top output shaft of the driver 1013;

[0041] The blade assembly 1014 on the top output shaft of the driver 1013 rotates under the drive of the driver 1013, generating power to propel the drone in flight. It is a key power component for drone flight.

[0042] See Figures 3-5 An inclined support leg assembly 1015 is fixedly connected to the outer side of the body mechanism 1. There are four support leg assemblies 1015 in total, and each pair of longitudinally adjacent support leg assemblies 1015 forms a group. A support assembly 1016 is fixedly connected to the outer side of each group of support leg assemblies 1015.

[0043] The four outrigger assemblies 1015 and the two support assemblies 1016 on the outside of the body structure 1 provide support during take-off and landing of the drone, thereby enhancing the stability of the drone when it is parked.

[0044] During operation, the flight of this UAV relies on the coordinated work of the boom assembly 1012, the driver 1013, and the blade assembly 1014. The boom assembly 1012 has four locations, which are tilted and fixed at the four corners of the outer side of the body structure 1 to provide support for the entire power system. The driver 1013 is installed inside the boom assembly 1012 as a power source. Its top output shaft is connected to the blade assembly 1014. When the driver 1013 is started, the output shaft drives the blade assembly 1014 to rotate at high speed. When the blade assembly 1014 rotates, it pushes the air to generate a reaction force, thereby providing lift for the UAV, enabling the UAV to fly stably in the air and move towards the target river area.

[0045] Upon reaching the target sampling area, the servo motors 301 on the outer sides of the two sets of support mechanisms 3 at the bottom of the body mechanism 1 are activated. The output shaft of the servo motors 301 drives the winding wheel 3011 to rotate, and the winding wheel 3011 begins to unwind the traction rope 3012. Under the guidance of the guide wheel at the bottom of the body mechanism 1, the traction rope 3012 extends smoothly downward. The hanging ring A3013 at the bottom of the traction rope 3012 is connected to the hanging ring B3014. The sampling bucket 3015 fixed inside the hanging ring B3014 descends accordingly. The counterweight 3016 connected to the bottom of the sampling bucket 3015 keeps the sampling bucket 3015 vertically stable during the descent, ensuring that the sampling bucket 3015 can smoothly sink into the sewage for sampling. After the sampling bucket 3015 has collected sewage, the servo motor 301 is activated again to rotate in the opposite direction. The winding wheel 3011 begins to wind the traction rope 3012, lifting the sampling bucket 3015 back to the drone.

[0046] After the sampling bucket 3015 is lifted back to the drone, the plug mechanism 2 and the magnetic component 201 are used to prevent sewage leakage. The plug mechanism 2 is installed at the bottom of the body mechanism 1. The main body is made of rubber and has good sealing performance. The magnetic component 201 is a ring electromagnet structure and is fixed on the outside of the plug mechanism 2. When the sampling bucket 3015 rises close to the plug mechanism 2, the magnetic component 201 is energized. The magnetic component 201 generates magnetism and attracts the sampling bucket 3015 to the plug mechanism 2. At this time, the rubber plug mechanism 2 tightly blocks the opening of the sampling bucket 3015, forming an effective closed structure and preventing sewage leakage from the sampling bucket 3015 during the drone's flight.

[0047] During the drone's flight and sampling, the gimbal module 101 and camera 1011 play a role in river patrol. The gimbal module 101 is rotatably connected to the groove at the front end of the body mechanism 1 and can rotate flexibly. The camera 1011 is fixed to the front end of the gimbal module 101. As the gimbal module 101 rotates, the camera 1011 can adjust the shooting angle to record the river from all angles. By observing the images captured by the camera 1011, operators can promptly detect abnormalities in the river, such as sewage discharge points and floating objects, providing a basis for river management.

[0048] The four outrigger assemblies 1015 and the two support assemblies 1016 on the outside of the body structure 1 play a key role in the take-off and landing of the UAV. When the UAV lands, the outrigger assembly 1015 is the first to touch the ground. The inclined design allows the outrigger assembly 1015 to better adapt to different terrains. The support assembly 1016 further enhances the stability of the support, prevents the UAV from tipping over when landing, and ensures that the UAV is safely and stably parked.

[0049] In summary, this device can quickly adsorb and position the sampling container 3015 by utilizing the magnetic suction component 201.

[0050] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
