[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific implementation methods and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] like Figures 1 to 3 As shown, the present application provides a floating dust detection device based on a drone, including a drone body 1 and a protection box 3, the protection box 3 is detachably connected to the drone body 1, an inlet and outlet 301 is provided on the top plate of the protection box 3 away from the drone body 1, a groove 302 is provided on the inner wall of the inlet and outlet 301, an opening and closing component is arranged in the groove 302, and the opening and closing component is used for opening and closing the inlet and outlet 301, a floating dust sensor 6, a controller 5 and a telescopic component are installed in the protection box 3, one end of the telescopic component is connected to the inner wall of the protection box 3, and the other end is connected to the floating dust sensor 6, the telescopic component can drive the floating dust sensor 6 to pass through the inlet and outlet 301 and extend out of the protection box 3, and the controller 5 is electrically connected to the floating dust sensor 6 and the telescopic component respectively.

[0024] Specifically, the protection box 3 is detachably connected to the top of the drone body 1, and can be easily installed and disassembled, which is very convenient for maintenance and replacement. An inlet and outlet 301 is arranged at the center of the top plate of the protection box 3, and a groove 302 is arranged on the inner wall of the inlet and outlet 301. An opening and closing component is arranged in the groove 302, which is used for opening and closing the inlet and outlet 301, so that the floating dust sensor 6 can be protected from the influence of the external environment when it is not in working state. The internal structure of the protection box 3 is compact, and the floating dust sensor 6, the controller 5 and the telescopic component are integrated therein. Among them, one end of the telescopic component is fixed to the bottom surface of the protection box 3, and the other end is closely connected to the floating dust sensor 6. During the take-off stage of the drone, the floating dust sensor 6 is safely hidden in the protection box 3, avoiding the strong downwash airflow generated when the propeller is running, and preventing the ground dust from being rolled up and adsorbed on the surface of the floating dust sensor 6, so as to prevent the accuracy of the subsequent atmospheric floating dust detection from being adversely affected. Once the drone reaches the preset detection point, the opening and closing assembly opens, and the telescopic assembly drives the floating dust sensor 6 to smoothly pass through the inlet and outlet 301, and then extend out of the protection box 3, thereby officially starting the collection of floating dust concentration. At this time, with the assistance of the telescopic assembly, the floating dust sensor 6 reaches a suitable height and maintains a safe distance from the rotating propeller, effectively avoiding the impact of the air flow disturbance caused by the operation of the propeller on the surrounding air environment, ensuring the uniform distribution of floating dust around the drone, and thus ensuring the authenticity and reliability of the detection data. After the detection task is completed, the telescopic assembly is started again to safely recycle the floating dust sensor 6 into the protection box 3, providing comprehensive protection for the sensor to prevent it from being damaged externally. As a core component, the controller 5 is electrically connected to the floating dust sensor 6 and the telescopic assembly respectively, responsible for receiving the data of the floating dust sensor 6, controlling the action of the telescopic assembly, and transmitting the data to the ground station or other monitoring equipment through wireless signals.

[0025] The working process is as follows:

[0026] Before the drone takes off, the dust sensor 6 is safely stored in the protection box 3. The tight closure of the opening and closing components effectively isolates the dust pollution that may be caused by the propeller underwash airflow. When the drone arrives at the target detection point according to the preset route, the controller 5 sends an electric command to let the telescopic component start working, drive the dust sensor 6 to smoothly pass through the opening and closing component and extend from the protection box 3, and adjust the dust sensor 6 to the optimal detection height so that it keeps a sufficient distance from the rotating propeller, and then starts to collect atmospheric dust concentration data. At the same time, the controller 5 stores the data of the dust sensor 6. After completing the detection task, the controller 5 sends an electric command again to let the telescopic component safely retract the dust sensor 6 into the protection box 3, and the opening and closing component is closed to form a sealed state, thereby providing comprehensive protection for the dust sensor 6.

[0027] The above technical solution adopted by the floating dust detection device based on drone provided in this application can achieve the following beneficial effects:

[0028] The present application sets a protection box 3, and when it is not in operation, the dust sensor 6 is placed in the protection box 3, which effectively isolates the ground dust and particles rolled up by the airflow under the propeller when the drone takes off, and prevents these particles from adhering to the dust sensor 6, thereby avoiding interference with subsequent atmospheric dust detection, improving the accuracy of the detection result, and reducing data deviation; by setting a telescopic component, when working, the telescopic component can lift the dust sensor 6 to a certain height to keep it away from the propeller of the drone, avoiding the disturbance of the surrounding air by the strong airflow generated when the propeller rotates, preventing uneven distribution of dust in the area near the drone, and improving the accuracy of the detection data.

[0029] Based on the above implementation scheme, the drone-based floating dust detection device further includes a wind deflector 2 , one side of which is connected to the drone body 1 , and the side away from the drone body 1 extends in a direction away from the drone body 1 .

[0030] Specifically, one side of the wind deflector 2 is firmly connected to the drone body 1, ensuring that the wind deflector 2 can be stably attached to the drone body 1 and will not be displaced or fall off due to the influence of airflow during flight. The other side of the wind deflector 2, that is, the side away from the drone body 1, extends in the direction away from the drone 1. The setting of the wind deflector 2 effectively changes the path of the airflow around the drone when it is flying in the air. What is particularly critical is that the wind deflector 2 can block and guide the strong airflow generated by the propeller when it is running, preventing this part of the airflow from rushing into the detection range of the dust sensor 6, thereby reducing the impact of the airflow generated by the rotation of the propeller on the distribution of dust, so that the airflow in the detection area remains relatively stable, thereby ensuring that the data collected by the dust sensor 6 is more real and reliable.

[0031] As a more preferred embodiment, the air guide plate 2 is tilted and has an arc shape.

[0032] Specifically, one side of the wind deflector 2 is firmly connected to the drone body 1, and the other side of the wind deflector 2, that is, the side away from the drone body 1, extends in the direction away from the drone 1 and is inclined toward the propeller. The wind deflector 2 is designed to be an arc-shaped structure. Based on the above design, it is not only aesthetically pleasing, but more importantly, when the airflow generated by the propeller on the drone hits the inner arc surface of the wind deflector 2, the airflow can be concentrated and can be smoothly guided and dispersed, thereby reducing the turbulent effect of the airflow and enhancing the stability of the airflow. By concentrating and dispersing the airflow, it is possible to effectively avoid the strong airflow generated by the propeller from rushing to the detection range of the floating dust sensor 6, so as to avoid making the floating dust concentration within the detection range uneven, thereby improving the reliability and accuracy of the data collected by the floating dust sensor 6.

[0033] In one embodiment, the telescopic assembly includes a first telescopic rod 4, one end of the first telescopic rod 4 is connected to the bottom of the protection box 3, and the other end is connected to the floating dust sensor 6, and the first telescopic rod 4 is electrically connected to the controller 5.

[0034] Specifically, the telescopic assembly includes a first telescopic rod 4, one end of which is connected to the bottom of the protection box 3, and the other end is connected to the floating dust sensor 6, and the first telescopic rod 4 is electrically connected to the controller 5. Among them, the first telescopic rod 4 belongs to but is not limited to any one of an electric telescopic rod, a pneumatic telescopic rod and a hydraulic telescopic rod. When the drone is not working or in bad weather conditions, the controller 5 will issue a command to shrink the first telescopic rod 4, so that the floating dust sensor 6 is completely stored in the protection box 3 to prevent it from being damaged by the external environment. When the drone is ready to start the data collection task, the controller 5 will drive the first telescopic rod 4 to extend according to a preset program or real-time instructions, and push the floating dust sensor 6 out of the protection box 3 to a predetermined position. During the flight, if an emergency (such as strong wind, obstacles approaching, etc.) is encountered, the controller 5 can respond quickly, by adjusting the extension degree of the first telescopic rod 4, changing the position of the floating dust sensor 6 to avoid potential threats, while maintaining the continuity and accuracy of data collection as much as possible. After completing the task, or when encountering unpredictable danger, the controller 5 will immediately instruct the first telescopic rod 4 to retract the floating dust sensor 6 and store it safely in the protection box 3 to ensure that the sensor will not be damaged.

[0035] In a preferred embodiment, a protective cover 7 is installed at the telescopic end of the telescopic assembly, the protective cover 7 is sleeved on the floating dust sensor 6, and a plurality of air inlets 701 are opened on the protective cover 7.

[0036] Specifically, a protective cover 7 is installed at the telescopic end of the telescopic component, and the protective cover 7 covers the floating dust sensor 6, forming a protective layer, so that the floating dust sensor 6 is completely inside the protective cover 7. A number of air inlets 701 are provided on the protective cover 7, and the air inlets 701 are evenly distributed on the side wall or top of the protective cover 7, so as to ensure that sufficient air can circulate from all directions. The protective cover 7 is connected to the free end of the telescopic component through threads, buckles or special fixings to ensure that the protective cover 7 is firmly installed, and it is also convenient for maintenance and replacement. The internal shape of the protective cover 7 matches the shape of the floating dust sensor 6, so as to ensure that the floating dust sensor 6 can be accurately and correctly placed in the center of the protective cover 7, and maintain a suitable distance from the air inlet 701 so that the air can circulate smoothly. The protective cover 7 is designed as a semi-enclosed shell structure, and its shape is determined according to the shape of the floating dust sensor 6, usually square, cylindrical or similar streamlined design to reduce flight resistance. In terms of material, the protective cover 7 is made of lightweight and high-strength materials such as engineering plastics and aluminum alloys, so as to ensure that sufficient protection is provided without adding too much weight burden. The design of the air inlet 701 usually takes into account both ventilation and protection, and includes a fine filter or a channel of special shape to block the entry of large particles or foreign matter, while allowing air and tiny particles (such as floating dust) to pass smoothly, so as to achieve the purpose of protecting the sensor without affecting data collection. In addition, the protective cover 7 can effectively prevent direct collisions from the outside, such as collisions from branches, birds or other flying objects, thereby reducing physical damage to the floating dust sensor 6.

[0037] In one embodiment, the opening and closing assembly includes two movable plates 8 and an actuator. The movable plates 8 are slidably guided in the groove 302. The two movable plates 8 are connected to the actuator on one side away from each other. The end of the actuator away from the movable plates 8 is connected to the inner wall of the groove 302.

[0038] Specifically, the opening and closing assembly includes two movable plates 8, and an actuator is connected to the outer side (i.e., the side away from each other) of each movable plate 8, and the actuator can drive the contact and separation of the two movable plates 8. The movable plate 8 is connected to the groove 302 through a sliding guide, that is, the edge of the movable plate 8 has a profile that matches the shape of the groove 302, and can slide freely in the groove 302 without falling out, thereby ensuring the smooth movement of the movable plate 8 and the accuracy of positioning. One end of each actuator is firmly connected to the corresponding movable plate 8, such as direct welding, bolt fixing or any other suitable mechanical connection method, to ensure that the actuator can effectively transmit external force to the movable plate 8. The other end of the actuator is fixed to the inner wall of the groove 302, and this fixing method also requires sufficient strength and stability to withstand the force generated during the opening and closing process. Generally, this can be achieved by pre-installing fixing points on the inner wall of the groove 302, and then fixing the ends of the actuator to these points using screws, pins or similar fasteners. When an external force is applied to the actuator, the force is transmitted to the movable plate 8 through the actuator, pushing or pulling the movable plate 8 to slide along the groove 302. Since the actuators of the two movable plates 8 are located on both sides, they can move simultaneously and symmetrically, maintaining the balance and coordination of the opening and closing actions, and improving the efficiency of the opening and closing assembly.

[0039] In one embodiment, the actuator includes a second telescopic rod, and the two movable plates 8 are connected to the second telescopic rod on the side away from each other, and the end of the second telescopic rod away from the movable plate 8 is connected to the inner wall of the groove 302, and the second telescopic rod is electrically connected to the controller 5.

[0040] Specifically, the actuator includes a second telescopic rod, which is any one of an electric telescopic rod, a pneumatic telescopic rod and a hydraulic telescopic rod. The side of each movable plate 8 that is away from each other (i.e., the side facing the inner wall of the groove) is connected to the telescopic end of the second telescopic rod, and the other end of the second telescopic rod is fixed to the inner wall of the groove 302 to form a fixed fulcrum, which can be achieved by bolts, welding or other mechanical fixing methods to ensure that the second telescopic rod has sufficient support and stability when working. The second telescopic rod is electrically connected to the controller 5 through a wire, and the controller 5 can respond to external signals to control the second telescopic rod to complete the opening and closing of the two movable plates 8 without manual intervention, which greatly improves the convenience and safety of operation.

[0041] In a preferred embodiment, the actuator includes a return spring 10, and the two movable plates 8 are connected to the return spring 10 on the side away from each other. The end of the return spring 10 away from the movable plate 8 is connected to the inner wall of the groove 302, and the two movable plates 8 are connected on the side with an inclined surface 801.

[0042] Specifically, the actuator includes a reset spring 10. The two movable plates 8 are connected to a reset spring 10 on the side away from each other. The other end of the reset spring 10 is fixed on the inner wall of the groove 302, ensuring that when the movable plates 8 are separated due to the passage of an object, they can be automatically reset under the elastic action of the reset spring 10, that is, restored to the initial closed state. Inclined surfaces 801 are set on the upper and lower surfaces of the two movable plates 8 on the side where they are connected. The design of the inclined surface 801 enables the first telescopic rod 4 to drive the floating dust sensor 6 to pass smoothly through the inlet and outlet 301, and at the same time, the thrust forces the movable plates 8 to separate in opposite directions to achieve automatic opening. Through the design of the inclined surface 801 and the cooperation of the reset spring 10, the automatic opening and closing of the two movable plates 8 are achieved without additional manual operation, thereby improving work efficiency. The automatic reset function ensures that the movable plates 8 can be automatically closed even when unattended, reducing safety hazards. Since the opening and closing action mainly depends on the principles of physical mechanics rather than complex electronic control, the maintenance of the component is relatively simple, reducing maintenance costs.

[0043] Based on the above embodiment, the two movable plates 8 are in surface contact at one side thereof.

[0044] Specifically, a plane contact surface is designed on one side of the two movable panels 8, and the contact surface fits tightly when the two movable panels 8 are closed to form a seamless connection. Sealing materials, such as rubber gaskets or sealing strips, can also be added to the contact surface of the movable panels 8 to further enhance the sealing effect when closed and prevent dust, water vapor and other foreign substances from entering the protective box. Compared with point or line contact, surface contact can significantly improve the sealing performance between the two movable panels 8 and effectively isolate the influence of the external environment.

[0045] In one embodiment, a sealing gasket 9 is disposed on the outer side of the inlet and outlet 301 .

[0046] Specifically, a sealing gasket 9 matching the contour of the inlet and outlet 301 is installed on the outer side of the inlet and outlet 301 of the protection box 3 to ensure that it fits tightly with the inlet and outlet 301. The outer edge of the sealing gasket 9 is firmly connected to the surface of the top plate, and an opening is provided at its center, so that key components such as the floating dust sensor 6 and the first telescopic rod 4 can pass smoothly, and during the inlet and outlet process, the sealing gasket 9 always fits on the surface of the first telescopic rod 4 or the protective cover 7, thereby enhancing the sealing performance at the inlet and outlet 301 and preventing floating dust from entering the protection box 3. The sealing gasket 9 is usually made of an elastic material, such as rubber, silicone or a specific polymer, to ensure that it can fit tightly with the first telescopic rod 4 or the protective cover 7 when under pressure to form an effective seal, which is crucial to prevent dust and impurities from entering the protection box 3.

[0047] The specific working process of this application is as follows:

[0048] Before the drone takes off, the floating dust sensor 6 is safely stored in the protection box 3, and the inlet and outlet 301 on the protection box 3 is tightly sealed by two movable plates 8. When the drone arrives at the target detection point according to the preset route, the controller 5 sends an electric command to start the first telescopic rod 4. The rising action of the first telescopic rod 4 first touches the inclined surface 801 of the movable plate 8. As it continues to rise, it forces the two movable plates 8 to move in opposite directions, and at the same time compresses the reset spring 10, so that the protective cover 7 smoothly passes through the opening of the sealing pad 9, and finally adjusts the floating dust sensor 6 to the optimal detection height, so that it keeps a sufficient distance from the rotating propeller, and then starts to collect atmospheric floating dust concentration data. At the same time, the controller 5 stores the data of the floating dust sensor 6. After completing the detection task, the controller 5 activates the first telescopic rod 4 again, and safely retracts the floating dust sensor 6 into the protection box 3. At this time, the reset spring 10 begins to reset naturally after losing the extrusion force, pushing the two movable plates 8 to close again, forming a sealed state, and providing comprehensive protection for the floating dust sensor 6. During the whole process, the edge of the opening of the sealing pad 9 is always in close contact with the surface of the protective cover 7 or the first telescopic rod 4 .

[0049] The above-described embodiments only express the way of equipment layout of the present application, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application; it should be pointed out that for ordinary technicians in this field, several adjustments and improvements can be made without departing from the concept of the present application, which all belong to the scope of protection of the present application; therefore, the scope of protection of the patent of this application should be based on the attached claims.
