Description

Technical Field

[0001] This utility model relates to the field of washing drones, specifically a plant protection drone. Background Technology

[0002] Agricultural drones are large unmanned aerial vehicles that primarily serve agricultural and forestry production. They are equipped with functions such as agricultural monitoring, material transport, and fertilization. In other fields, such as photovoltaic power generation, agricultural drones can use their spraying mechanisms to load cleaning agents into their pesticide tanks and then spray and clean photovoltaic panels.

[0003] In existing technologies, when using agricultural drones to clean inclined surfaces such as photovoltaic panels, the drones often need to plan their flight path in the area to be cleaned, spray the cleaning agent evenly onto the area, and then workers use electric brushes with long poles to scrub the inclined surfaces that have been sprayed with cleaning agent.

[0004] Regarding the aforementioned technologies, existing agricultural drones can often only perform simple cleaning agent spraying on inclined surfaces. Manual use of electric brushes is still required to thoroughly scrub the inclined surfaces. When the inclined surfaces to be cleaned are high, it is often difficult for workers to thoroughly scrub them with handheld electric brushes. This is especially evident when dealing with scenarios such as floating solar panels or rooftop solar panels, which can easily leave cleaning dead corners at the top of the inclined surfaces, affecting the overall cleaning effect.

[0005] In summary, existing agricultural drones have blind spots when cleaning inclined surfaces at high altitudes, and manual brushing is inefficient. Utility Model Content

[0006] Based on this, the purpose of this utility model is to provide an agricultural drone to solve the technical problems of existing agricultural drones having blind spots when dealing with cleaning of high-altitude inclined surfaces, and low efficiency of manual brushing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a plant protection drone, including a body, an installation plate fixedly connected to the middle of the body, a sleeve rod connected to the installation plate, a sliding rod slidably connected inside the sleeve rod, and an electric brush disc, the electric brush disc being rotatably connected to the bottom end of the sliding rod, and a hose connected to the spray nozzle of the body extending to the electric brush disc.

[0008] By adopting the above technical solution, after the drone flies over the inclined surface and sprays the cleaning agent, the electric brush plate set at the bottom of the telescopic slide bar structure is used to scrub the inclined surface. By controlling the flight trajectory of the drone, the inclined surface can be thoroughly scrubbed while spraying the cleaning agent, eliminating the need for manual high-altitude operations, effectively avoiding the generation of cleaning dead corners, and significantly improving cleaning efficiency and operational safety.

[0009] The present invention is further configured such that the sleeve rod is provided with a sliding groove along its own length direction, the diameter of the sliding rod is the same as the inner diameter of the sleeve rod, and a limiting screw that passes through the sliding groove along the radial direction of the sleeve rod is fixedly connected at the top end.

[0010] Preferably, the limiting screw is used to restrict the relative rotation of the slide rod and the sleeve rod along their own axis, and at the same time, it can be used in conjunction with the slide groove to limit the slide rod in the axial direction.

[0011] The present invention is further configured such that the top end of the sleeve rod is coaxially and fixedly connected to the mounting plate, and the bottom end is connected to an electric brush plate through a second universal joint.

[0012] Preferably, the electric brush disc is tilted relative to the machine body by using the bidirectional rotating shafts of the second universal joint that are orthogonal to each other, so as to brush the tilted surface.

[0013] The present invention is further configured such that a support frame is fixedly connected to the bottom end of the machine body, and when the support frame is in contact with the ground, the limiting screw at the top of the slide rod does not slide to the top of the slide groove.

[0014] Preferably, the drone body is supported by a support frame while keeping the sleeve vertical.

[0015] The present invention is further configured such that a plug rod is fixedly connected to the bottom end of the mounting plate, a sleeve rod is connected to the bottom end of the plug rod through a first universal joint, and an electric brush plate is connected to the bottom end of the slide rod through a second universal joint.

[0016] Preferably, the drone body can be placed directly on the ground, making it convenient to replace the drone's battery or replenish cleaning fluid.

[0017] The present invention is further configured such that the axes of the first universal joint and the second universal joint are respectively in the same plane and parallel to each other.

[0018] Preferably, the electric brush disc can be tilted relative to the machine body along its own length and width directions respectively.

[0019] The present invention is further configured such that the electric brush disc cannot rotate relative to the machine body along the axis of the insertion rod.

[0020] Preferably, when the machine body rotates and adjusts its orientation in the horizontal plane, it can simultaneously drive the electric brush disc to adjust its orientation.

[0021] The present invention is further configured such that a connecting plate is coaxially fixedly connected to the edge of the insertion rod, the top end of the insertion rod can pass through the mounting plate, and the connecting plate and the mounting plate are fixedly connected by bolts.

[0022] Preferably, bolts are used for easy installation and removal of the insert rod.

[0023] The present invention is further provided that the mounting plate is also provided with a fixing plate with the same diameter as the connecting plate, and the center of the fixing plate is also provided with a through hole for the insertion rod to pass through. The connecting plate and the fixing plate are fastened together by bolts.

[0024] Preferably, the stability of the plug connection state is further improved.

[0025] The present invention is further configured such that a compression spring is provided inside the sleeve rod at a position higher than the slide groove, and the top of the slide rod can contact the compression spring before the limiting screw contacts the top of the slide groove.

[0026] Preferably, it acts as a buffer when the slide bar slides upward, preventing the limit screw from directly hitting the edge of the slide groove and causing damage.

[0027] In summary, the present invention has the following main advantages: This invention connects a telescopic sliding rod structure to the underside of an agricultural drone. After the drone flies over an inclined surface and sprays cleaning agent, an electric brush plate at the bottom of the telescopic sliding rod structure scrubs the inclined surface. By controlling the drone's flight trajectory, the inclined surface can be thoroughly scrubbed while the cleaning agent is being sprayed, eliminating the need for manual high-altitude operations, effectively avoiding the formation of cleaning dead spots, and significantly improving cleaning efficiency and operational safety.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] First embodiment: For an agricultural drone, please refer to [link / reference]. Figure 1-5 The device includes a body 1, with a mounting plate 2 fixedly connected to the middle of the body 1. Specifically, when the body 1 is parked on the ground, the mounting plate 2 is parallel to the ground. The mounting plate 2 is connected to a sleeve rod 3, and a sliding rod 4 is slidably connected inside the sleeve rod 3.

[0033] It also includes an electric brush disc 5, which is rotatably connected to the bottom end of the slide bar 4. The spray nozzle of the body 1 is connected to a hose that extends to the electric brush disc 5. Specifically, the electric brush disc 5 includes a motor and a brush disc driven by the motor. The electric brush disc 5 has an interface for connecting the hose at the position facing the brush disc. One end of the liquid supply hose is connected to the spray nozzle of the body 1, and the other end of the hose is connected to the interface located on the electric brush disc 5.

[0034] Furthermore, the sleeve rod 3 is provided with a groove 301 along its own length direction. The diameter of the slide rod 4 is the same as the inner diameter of the sleeve rod 3, and a limiting screw 401 is fixedly connected at the top end, which passes through the groove 301 along the radial direction of the sleeve rod 3. The limiting screw 401 restricts the relative rotation of the slide rod 4 and the sleeve rod 3 along their own axis, and can also cooperate with the groove 301 to limit the axial direction of the slide rod 4.

[0035] Furthermore, a compression spring is provided inside the sleeve rod 3 at a position higher than the slide groove 301. Before the limiting screw 401 contacts the top of the slide groove 301, the top of the slide rod 4 can first contact the compression spring, which plays a buffering role when the slide rod 4 slides upward, preventing the limiting screw 401 from directly hitting the edge of the slide groove 301 and causing damage.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 1-4The top end of the sleeve rod 3 is coaxially fixedly connected to the mounting plate 2, and the bottom end is connected to the electric brush plate 5 through the second universal joint 7. The electric brush plate 5 is tilted relative to the machine body 1 by using the bidirectional rotating shafts of the second universal joint 7, thereby brushing the tilted surface. Compared with the existing technology, the cleaning efficiency of the inclined surface is greatly improved, especially when dealing with working scenarios such as water photovoltaic panels or full photovoltaic panels on the roof of a pitched roof.

[0037] Furthermore, a support frame 101 is fixedly connected to the bottom of the body 1. When the support frame 101 is in contact with the ground, the limiting screw 401 at the top of the slide bar 4 does not slide to the top of the slide groove 301. The support frame 101 supports the body 1 of the drone while keeping the sleeve 3 in a vertical state.

[0038] Specifically, when the drone takes off, after the support frame 101 leaves the ground, the electric brush 5 can only leave the ground when the slide bar 4 slides to the bottom position in the sleeve 3. When the drone needs to clean the plane, the body 1 flies above the plane to be cleaned, and after the electric brush 5 contacts the plane to be cleaned, the body 1 lowers its altitude so that the limit screw 401 of the slide bar 4 slides to the middle position of the slide groove 301. Then the drone can start to fly horizontally to clean the plane.

[0039] Second embodiment: For an agricultural drone, please refer to [link / reference]. Figure 1-5 Based on the first embodiment, the difference from the first embodiment is that the bottom end of the mounting plate 2 is fixedly connected to the insertion rod 9, the bottom end of the insertion rod 9 is connected to the sleeve rod 3 through the first universal joint 6, and the bottom end of the slide rod 4 is connected to the electric brush plate 5 through the second universal joint 7, so that the body 1 of the drone can be directly placed on the ground, which is convenient for the drone to replace the battery or replenish the cleaning fluid.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 1-5 The axes of the first universal joint 6 and the second universal joint 7 are in the same plane and parallel to each other, so that the electric brush disc 5 can be tilted relative to the body 1 along its own length and width directions. Specifically, the electric brush disc 5 cannot rotate relative to the body 1 along the axis of the insertion rod 9, so that when the body 1 rotates and adjusts its orientation in the horizontal plane, it can synchronously drive the electric brush disc 5 to adjust its orientation.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 2-4 The edge of the insertion rod 9 is coaxially fixedly connected to the connecting plate 901. The top of the insertion rod 9 can pass through the mounting plate 2. The connecting plate 901 and the mounting plate 2 are fixedly connected by bolts. The insertion rod 9 can be easily installed and removed using bolts, thereby realizing the quick replacement or maintenance of the electric brush plate 5 and adapting to the needs of different cleaning scenarios.

[0042] Furthermore, the mounting plate 2 is also equipped with a fixing plate 8 with the same diameter as the connecting plate 901. The center of the fixing plate 8 is also provided with a through hole for the insertion rod 9 to pass through. The connecting plate 901 and the fixing plate 8 are fastened together by bolts, which further improves the stability of the insertion rod 9 when connected and effectively prevents the connection from loosening due to vibration during flight. This ensures that the electric brush plate 5 always maintains a stable posture during operation. At the same time, the integrated design of the fixing plate 8 and the mounting plate 2 enhances the overall rigidity of the structure and improves the operational reliability of the UAV under complex working conditions.

[0043] In practical operation, this utility model is as follows: After the drone is equipped with a battery and filled with cleaning fluid, it flies to the top of the slope to be cleaned and slowly descends to make the electric brush 5 contact the slope. At the same time, the drone body 1 sprays cleaning fluid into the location of the electric brush 5 through the hose. The drone flies horizontally from the bottom of the slope to the top of the slope, and the electric brush 5 always keeps in contact with the slope. Meanwhile, the slide bar 4 gradually slides back into the sleeve bar 3. By repeating this process, the agricultural drone can easily clean the slope.
