Description

Technical Field

[0001] The present invention relates to the technical field of free tick monitoring, and in particular to a free tick on-site monitoring device based on an unmanned aerial vehicle. Background Art

[0002] Ticks are parasitic arthropods that live mainly in natural environments such as grasslands, forests, and bushes. Ticks have a very sensitive sense of smell and are very sensitive to the smell of sweat and carbon dioxide. Ticks use this ability to wait for their hosts to approach them in places such as grass on the sides of the road, the tops of bushes, and the surface of tree trunks. Once the host approaches, they will actively contact it and cling to the host's body surface to feed on blood. Ticks are the vectors of many important zoonotic diseases and can spread a variety of diseases to humans and animals. In order to understand and effectively control ticks, it is necessary to monitor the distribution and number of ticks in the living environment so as to formulate appropriate control measures.

[0003] The tick flag is a tool used to monitor ticks, mainly used by disease control agencies for vector monitoring. It is a white cotton flag used to monitor the density of free ticks in outdoor environments through the flag method. This method involves dragging the tick flag evenly across the grass and then checking the ticks attached to the flag to understand the distribution and density of ticks.

[0004] At present, the commonly used monitoring method is to manually drag tick flags through vegetation to capture ticks. However, in many areas such as high grass and shrubs, it is difficult to walk manually and it is easy to be bitten by ticks. This is not only inefficient but also dangerous. After the ticks are captured on the tick flags, they need to be removed manually and the tick flags need to be cleaned. The monitoring efficiency is low and it is difficult to carry out continuous and large-scale monitoring work. Therefore, a free tick field monitoring device based on drones is proposed.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] Example: Reference Figure 1-Figure 7 A free tick on-site monitoring device based on a drone comprises a drone body 1, a rotor 2 and a landing gear 3, wherein the rotors 2 are evenly spaced on the outer wall of the drone body 1, the landing gear 3 is symmetrically fixed to the bottom of the drone body 1, and also comprises a tick flag 4 arranged at the bottom of the drone body 1, a monitoring chamber 5 is fixedly connected to the landing gear 3, the tick flag 4 passes through the center of the monitoring chamber 5, and a winding portion for rolling up the tick flag 4 is arranged at the bottom of the drone body 1; wherein an exhaust box 21 is fixedly connected to the connecting rod of the rotor 2, and an exhaust portion for generating suction in the monitoring chamber 5 is arranged in the exhaust box 21.

[0024] Reference Figure 1-Figure 3 The winding part includes a winding drum 6, which is fixed at the bottom of the drone body 1, and a winding shaft 61 is rotatably connected inside the winding drum 6. A servo motor 62 is fixedly connected to the outer wall of the end of the winding drum 6, and the rotating shaft of the servo motor 62 is fixedly connected to the end of the winding shaft 61. A pull rope 63 is fixedly wound on the winding drum 6, and three groups of pull ropes 63 are arranged at equal intervals along the side wall of the winding shaft 61. The bottom end of each group of pull ropes 63 is fixedly connected to the top of the tick flag 4, and both sides of the bottom end of the tick flag 4 are fixedly connected with counterweight balls 64. The width of the tick flag 4 is equal to the length of the bottom opening of the winding drum 6 and the length of the upper and lower ports of the monitoring chamber 5; the spacing on both sides of the top of the monitoring chamber 5 is smaller than the spacing on both sides of the bottom, and the spacing on both sides of the top of the monitoring chamber 5 is equal to the thickness of the tick flag 4. The monitoring chamber 5 is arranged in an upward curved arc, and the bottom of the monitoring chamber 5 is rotatably connected with a flap 51 through a damping shaft.

[0025] By setting the above structure, firstly, the drone body 1 is lifted and moved to the top of the area to be monitored by remote control, and at this time, the servo motor 62 is controlled to rotate in the opposite direction, so that the reel 61 rotates in the opposite direction of the winding rope 63. At this time, under the gravity of the counterweight ball 64, the tick flag 4 will pass through the monitoring chamber 5 and drop out, and then by adjusting the height of the drone body 1 and the number of rotations of the servo motor 62, the tick flag 4 is spread on the top of the vegetation in the required monitoring area, and then the drone body 1 is controlled to move, so as to pull the tick flag 4 to move on the top of the vegetation. Ticks will hide in the top of grass and shrubs due to their nature, and will actively climb on objects that fit their movement. In this way, when the tick flag 4 sweeps over the top of the vegetation, the tick will first climb upwards. Secondly, the tick flag 4 is made of cotton cloth, and the tick is a multi-legged animal, so the tick can be hooked with cotton cloth to achieve the capture of the tick, which effectively saves manpower, improves the capture speed, and ensures the monitoring efficiency. Secondly, after the drone body 1 drags the tick flag 4 for a period of time, the drone body 1 is raised, and the servo motor 62 is controlled to rotate forward, so that the reel 61 rotates in the direction of the winding rope 63, so as to pull the tick flag 4 upward. When the tick flag 4 moves up into the monitoring chamber 5, the top port of the monitoring chamber 5 will fit with the two sides of the tick flag 4. At this time, when the tick flag 4 continues to move up, the top of the monitoring chamber 5 will sweep the ticks attached to the tick flag 4 down. After the drone body 1 drags the tick flag 4 for a period of time, The drone body 1 is raised, and the servo motor 62 is controlled to rotate forward, so that the reel 61 rotates in the direction of the winding rope 63, thereby pulling the tick flag 4 upward. When the tick flag 4 moves up into the monitoring chamber 5, the top port of the monitoring chamber 5 will fit with the two sides of the tick flag 4. At this time, when the tick flag 4 continues to move up, the top of the monitoring chamber 5 will sweep down the ticks attached to the tick flag 4 and vegetation residues, thereby realizing the collection of captured ticks and completing the cleaning and sorting of the tick flag 4, effectively improving the efficiency of monitoring and capturing.

[0026] In addition, in order to facilitate the capture of ticks, sweat can be smeared on the tick flag 4 to improve the trapping effect.

[0027] Reference Figure 3-Figure 5The exhaust part includes a driven shaft 7, which is rotatably connected to the exhaust box 21. An exhaust blade 71 is fixedly connected to the outer wall of the driven shaft 7 located in the exhaust box 21. The top of the driven shaft 7 passes through the exhaust box 21 and is connected to the rotating shaft of the rotor 2 through a pulley set 72. The bottom of the exhaust box 21 is fixed and connected to an exhaust pipe 73. An intake pipe 74 is fixedly connected to the outer wall of the monitoring chamber 5. A plurality of groups of intake holes 741 are evenly spaced on one side of the intake pipe 74 close to the inner cavity of the monitoring chamber 5. A dust filter bag 742 is fixedly connected to the intake hole 741, and the inner diameter of the intake hole 741 is smaller than the outer diameter of the smallest tick. The bottom end of the exhaust pipe 73 is fixed on the intake pipe 74 and connected to its inner cavity.

[0028] Through the arrangement of the above structure, the rotating shaft of the rotor 2 will drive the driven shaft 7 to rotate through the pulley set 72, so that the exhaust blade 71 rotates in the exhaust box 21, thereby generating a suction effect at the bottom of the exhaust box 21, and transmitting it to the monitoring chamber 5 along the exhaust pipe 73, the suction pipe 74 and the suction hole 741, thereby generating a suction effect on the side of the monitoring chamber 5 away from the tick flag 4, so that the swept ticks move toward the suction hole 741, and finally fall to the bottom of the monitoring chamber 5, so as to collect the captured ticks, effectively avoiding the situation that the ticks will be dropped from the bottom port of the monitoring chamber 5 during the collection process, ensuring the collection effect, and improving the accuracy of the monitoring results; and the cleaned tick flag 4 can be reused to realize continuous and large-scale monitoring work, thereby improving the monitoring efficiency.

[0029] Reference Figure 3 , Figure 5-Figure 7 , wherein, a piston chamber 8 is fixedly connected to the landing gear 3, a piston plate 81 is slidably connected in the piston chamber 8, a return spring 82 is fixedly connected between the top of the piston plate 81 and the inner wall of the piston chamber 8, an alcohol cylinder 83 is fixedly connected to the bottom end of the piston chamber 8, the piston chamber 8 is communicated with the inner cavity of the alcohol cylinder 83, a plurality of groups of atomizing nozzles 831 are arranged at equal intervals at the bottom of the alcohol cylinder 83, the output end of the atomizing nozzle 831 penetrates into the monitoring chamber 5, the atomizing nozzle 831 adopts a pressure nozzle, and the gravity of the liquid in the alcohol cylinder 83 is less than the opening thrust required for the atomizing nozzle 831, the vacuum box 21 Both sides of the top are fixed and connected with air ducts 84, the other end of the air duct 84 is connected with the top of the inner cavity of the piston chamber 8, and a conversion part for switching the gas flow direction is arranged between the two groups of air ducts 84; the conversion part includes a two-way cylinder 85, which is fixed on the top of the vacuum box 21, and the telescopic ends on both sides of the two-way cylinder 85 are fixedly connected with conversion plates 86, which penetrate the air duct 84 and slide in a sealing fit with it, and a straight air groove 861 and a turning air groove 862 are respectively opened on the conversion plate 86, which can be connected with the inner cavity of the air duct 84.

[0030] Through the arrangement of the above structure, in the process of collecting ticks, the conversion plates 86 at both ends are pulled back by the two-way cylinder 85, so that the straight air groove 861 and the air guide tube 84 are in a connected state. At this time, the airflow drawn into the vacuum box 21 will be filled into the piston chamber 8 along the air guide tube 84, thereby increasing the internal air pressure of the piston chamber 8, thereby pushing the piston plate 81 to move downward, thereby increasing the air pressure in the alcohol cylinder 83, so that the alcohol liquid stored in it is sprayed into the monitoring chamber 5 along the atomizing nozzle 831. When the ticks encounter alcohol, they will become dehydrated and eventually die, thereby inactivating the collected ticks, realizing the treatment of the ticks, and improving the safety of subsequent tick counting.

[0031] Among them, the bidirectional cylinder 85, the drone body 1 and the servo motor 62 are connected through electrical signals, and the drone body 1 is electrically connected to the remote controller. As described above, the existing electrical signal control technology is used to remotely control the operating status of the bidirectional cylinder 85, the drone body 1 and the servo motor 62, which effectively improves the monitoring efficiency.

[0032] Reference Figure 1-Figure 7 In the present invention, when in use, the drone body 1 is lifted and moved to the top of the area to be monitored by remote control. At this time, the servo motor 62 is controlled to rotate in the opposite direction, so that the reel 61 rotates in the opposite direction of the winding rope 63. At this time, under the gravity of the counterweight ball 64, the tick flag 4 will pass through the monitoring chamber 5 and drop out. Then, by adjusting the height of the drone body 1 and the number of rotations of the servo motor 62, the tick flag 4 is spread on the top of the vegetation in the required monitoring area. Then, the drone body 1 is controlled to move, thereby pulling the tick flag 4 to move on the top of the vegetation. Ticks will hide in the top of grass and shrubs due to their nature, and will actively climb on objects that fit their movement. In this way, when the tick flag 4 sweeps over the top of the vegetation, the tick will first climb up. Secondly, the tick flag 4 is made of cotton cloth, and the tick is a multi-legged animal. Therefore, the tick can be hooked with cotton cloth to capture the tick, which effectively saves manpower, improves the capture speed, and ensures the monitoring efficiency.

[0033] After the drone body 1 has been dragging the tick flag 4 for a period of time, the drone body 1 is raised. At this time, the servo motor 62 is controlled to rotate forward, so that the reel 61 rotates in the direction of the winding rope 63, thereby pulling the tick flag 4 upward. When the tick flag 4 moves up into the monitoring chamber 5, the top port of the monitoring chamber 5 will fit with the two sides of the tick flag 4. At this time, when the tick flag 4 continues to move up, the top of the monitoring chamber 5 will sweep the ticks attached to the tick flag 4 down; at the same time, the rotating shaft of the rotor 2 will drive the driven shaft 7 to rotate through the pulley group 72, so that the exhaust blade 71 rotates in the exhaust box 21, thereby producing a vacuum at the bottom of the exhaust box 21. Suction is generated and transmitted to the monitoring chamber 5 along the exhaust pipe 73, the suction pipe 74 and the suction hole 741, thereby generating suction on the side of the monitoring chamber 5 away from the tick flag 4, so that the swept ticks move toward the suction hole 741 and finally fall to the bottom of the monitoring chamber 5, so as to facilitate the collection of the captured ticks, and effectively avoid the situation that the ticks will fall from the bottom port of the monitoring chamber 5 during the collection process, thereby ensuring the collection effect and improving the accuracy of the monitoring results. There is no need to manually remove the ticks from the tick flag 4 later, which effectively improves the monitoring efficiency, and cleans the vegetation residues attached to the tick flag 4 to ensure the cleanliness of the tick flag 4. The air in the air pump box 21 is connected to the air pipe 84, and the air sucked into the air pump box 21 will be discharged along the turning air groove 862. In the process of collecting ticks, the conversion plates 86 at both ends are retracted by the two-way cylinder 85, so that the straight air groove 861 and the air pipe 84 are connected. At this time, the airflow drawn into the air pump box 21 will be filled into the piston chamber 8 along the air pipe 84, thereby increasing the internal air pressure of the piston chamber 8, thereby pushing the piston plate 81 to move downward, thereby increasing the air pressure in the alcohol cylinder 83, causing the alcohol liquid stored in it to be discharged along the turning air groove 862. The atomizing nozzle 831 is sprayed into the monitoring chamber 5. When the ticks encounter alcohol, they will be dehydrated and eventually die. The collected ticks are inactivated, the ticks are processed, and the safety of subsequent tick counting is improved. The tick flag 4 can then be lowered again for subsequent monitoring work. Finally, when the tick flag 4 has swept across the entire monitored area, the drone body 1 is controlled to return. After shutting down the drone body 1, the flap 51 can be turned downward to take out the ticks, thereby obtaining the number of captured ticks in the monitored area, which makes it convenient for staff to understand the distribution and corresponding density of ticks, so as to carry out subsequent disease and insect control work.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
