Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of forestry monitoring equipment, and particularly relates to a kind of unmanned aerial vehicle equipment for safety monitoring. BACKGROUND

[0002] The unmanned aerial vehicle equipment for safety monitoring is an intelligent unmanned aerial vehicle integrating a flight platform, a sensing monitoring module, a control communication module and a data processing / execution module. The core objective is to monitor safety risks (such as hidden dangers, disasters and illegal behaviors) in various scenes through remote, non-contact and automated operations to achieve early detection, early warning and early disposal. In the field of forestry safety monitoring, vegetation growth state monitoring, pest warning and ecological environment assessment all rely on a large amount of accurate plant leaf sample data. The collection efficiency and integrity of the leaf samples directly affect the scientificity and timeliness of the monitoring results.

[0003] Some existing technologies attempt to use unmanned aerial vehicles to carry collection devices for aerial leaf sample collection. For example, a forestry pest monitoring unmanned aerial vehicle disclosed in CN114313260A includes a unmanned aerial vehicle main body, a camera, a main control unit, a positioning unit and a paint marking device. The main control unit is used to transmit image data captured by the camera to a terminal control device to determine whether trees in a forest area have pests. The positioning unit is used to position the unmanned aerial vehicle main body when it is within a preset distance from a tree with pests and transmit the positioning position to the terminal control device to mark the position of the tree with pests once. The paint marking device is used to spray paint on the tree with pests to mark the position of the tree with pests twice, so that the tree with pests can be easily and quickly found when it is treated and handled, solving the problem of low efficiency of accurate marking of the tree with pests by manual methods when it is monitored.

[0004] The above device uses a driving device to link a shearing mechanism and a storage mechanism to collect leaf samples. That is, the storage mechanism is extended synchronously when the shearing mechanism starts shearing work, and the shearing mechanism is separated when the shearing mechanism is separated. The storage mechanism is retracted. Since the leaf sample needs to be located between the two shearing knives during collection, the extended storage device will push the leaf sample forward before shearing is completed, which will cause the leaf sample to be pushed away from the shearing area and the leaf sample to be broken off from the petiole, resulting in failure of leaf sample collection.

DETAILED DESCRIPTION

[0027] The application will be described in further detail below with reference to the drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the application and cannot be understood as limiting the scope of protection of the application. Those skilled in the art can make some non-essential improvements and adjustments to the application according to the above application content.

[0028] As shown in Figures 1-8 A UAV device for safety monitoring, comprising a UAV 1, a load bin 11 mounted on the lower part of the UAV 1, a transfer bin 12 sliding in the inside of the load bin 11, and two blades 14, the end of the transfer bin 12 away from the load bin 11 is rotationally connected with a baffle 121, the end of the transfer bin 12 away from the load bin is provided with a motor 122, the output end of the motor 122 is connected with the baffle 121, the upper part of the blade 14 is provided with a fixed plate 26 protruding from the blade edge of the blade 14, the inside of the load bin 11 is provided with a driving part two 3 for driving the transfer bin 12 to move and a driving part one 2 for driving the blade 14 to cut the leaf sample.

[0029] Specifically, the unmanned aerial vehicle 1 and the motor 122 are both prior art. The unmanned aerial vehicle 1 can be manually operated to carry the load bin 11 to perform leaf sample sampling operation. The motor 122 is started and stopped, i.e. started for half a cycle and stopped. The front end of the load bin 11 is provided with a limiting plate 111. One end of the limiting plate 111 is fixed to the load bin 11. The length direction of the limiting plate 111 is consistent with the length direction of the load bin 11. The cross section of the limiting plate 111 is in L-shaped structure. The transfer bin 12 is installed between the two groups of limiting plates 111. The transfer bin 12 is in sliding connection with the limiting plates 111. The transfer bin 12 is in structure of open in the upper part, the lower part and the front part. The transfer bin 12 can slide in the area between the two limiting plates 111 and the upper part inside the load bin 11. The baffle 121 is located at the side opening of the transfer bin 12 and is used to control the opening and closing of the side opening. The motor 122 drives the baffle 121 to rotate. The movement cycle is that when the transfer bin 12 slides out of the inside of the load bin 11, the motor 122 is started to drive the baffle 121 to rotate by ninety degrees to make the front part of the transfer bin 12 open. Then the motor 122 stops running. When the leaf sample is cut, the transfer bin 12 moves backward. The motor 122 is started to drive the baffle 121 to rotate reversely to close the front part of the transfer bin 12. Then the motor 122 stops running. The transfer bin 12 moves to the inside of the load bin 11. The two blades 14 can move to a specific position under the drive of the driving member 1 2 and approach each other to cut the leaf sample. After the cutting is completed, the two blades 14 are driven to retract into the inside of the load bin 11 by the driving member 1 2. In this process, the two blades 14 block the upper end opening of the transfer bin 12, so that the upper part of the transfer bin 12 is closed. That is, after the side opening of the transfer bin 12 is closed, the inside of the transfer bin 12 and the blades 14 form an approximately sealed cavity structure. The cut leaf sample is located in the cavity. The sealed cavity can prevent the leaf sample from being blown off during movement. After the blades 14 enter the inside of the load bin 11, the guide member 4 can guide the two blades 14 to slide away from each other. In order to drive the transfer bin 12 to slide, the driving member 2 3 is arranged in the inside of the load bin 11. The driving member 2 3 includes an electric telescopic rod 2 31 arranged in the right inside of the load bin 11. The front end of the electric telescopic rod 2 31 is provided with a mounting block 32. The mounting block 32 is rotationally connected with a gear 33 in the middle part. The right inside of the load bin 11 is provided with a toothed plate 1 34. The gear 33 is engaged with the upper part of the toothed plate 1 34. The right side of the transfer bin 12 is provided with a toothed plate 2 35. The gear 33 is engaged with the lower part of the toothed plate 2 35. The electric telescopic rod two 31 is a prior art, which can be controlled to be telescopic. The tooth plate one 34 is fixed in position, and the tooth plate two 35 is arranged on the right side of the transfer bin 12 which can slide. When the driving gear 33 is driven to move through the mounting block 32, the gear 33 rotates under the drive of the lower tooth plate one 34, and the gear 33 further drives the tooth plate two 35 to move, and the moving distance of the tooth plate two 35 is twice the moving distance of the gear 33, including the moving distance of the gear 33 and the moving distance of the gear 33 rotating to drive the tooth plate two 35 to move. In order to realize the action that the two blades 14 cooperate with the transfer bin 12 to move to shear the leaf sample, the driving part one 2 includes a moving plate 21 which slides in the load bin 11. The rear end of the blade 14 is provided with a sliding block 22. The moving plate 21 is provided with a sliding groove 221. The groove direction of the sliding groove 221 is consistent with the width direction of the blade 14. The sliding block 22 is located in the sliding groove 221 and forms a sliding guide cooperation with the sliding groove 221. The upper end of the sliding block 22 is provided with a protrusion which extends into a guide groove 23 and forms a sliding guide cooperation with the guide groove 23. The inside of the load bin 11 is provided with an electric telescopic rod one 24. The driving end of the electric telescopic rod one 24 is arranged on the rear side of the moving plate 21. The side of the fixed plate 26 close to the blade 14 is provided with a spring sheet 25. The other end of the spring sheet 25 is arranged on the upper part of the blade 14. When the blade 14 is opened, the spring sheet 25 is in a natural state. At this time, the two sides of the fixed plate 26 which are close to each other, that is, the clamping surface, is located between the two sides of the blade 14. By using the positional relationship between the clamping surface and the blade, in the process that the blade 14 is closed and shears the leaf sample, the two fixed plates 26 will contact the upper part of the leaf sample before the blade 14, that is, the leaf sample is fixed first and then sheared. The sliding block 22 and the electric telescopic rod one 24 are prior arts. The sliding block 22 can slide in the inside of the guide groove 23. The electric telescopic rod one 24 can drive the moving plate 21 to slide. The guide groove 23 is an L-shaped structure. Thus, the sliding block 22 cooperates with the shape of the guide groove 23 to realize the sliding of the moving plate 21 and the orderly opening and closing of the blade 14 in the forward and backward sliding process. The steps are as follows. The electric telescopic rod one 24 is started to drive the moving plate 21 to slide forward. When the moving plate 21 slides forward, the sliding block 22 slides in the guide groove 23. When the stroke of the electric telescopic rod one 24 is maximum, the front inclined surface of the guide groove 23 can drive the two sliding blocks 22 and the blade 14 to be close to each other. Before the two blades 14 cut the leaf sample, the two fixed plates 26 will first clamp and fix the upper part of the cutting position of the leaf sample. When the transfer bin 12 moves backward, the blade 14, the fixed plate 26 and the moving plate 21 remain stationary. When the transfer bin 12 is completely retracted into the load bin 11, the blade 14, the fixed plate 26 and the moving plate 21 move into the load bin 11. In this process, the blade 14 and the fixed plate 26 can always cover the upper end opening of the transfer bin 12, so that the chamber in the transfer bin 12 is always in an indirect sealing state, avoiding the opening of the upper end opening to cause the loss of the collected leaf sample.

[0030] Before the UAV 1 approaches the leaf sample, the motor 122 starts earlier than the driving part two 3, the motor 122 drives the baffle 121 to rotate and open, the UAV 1 carries the load compartment 11 forward, so that the sheared leaf sample is located at the front end of the load compartment 11, then the two blades 14 are driven by the driving part one 2 to slide out of the inside of the load compartment 11 and approach each other, at this time the leaf sample is located in front of the two blades 14, then the two fixed plates 26 will preferentially clamp and fix the upper part of the leaf sample, then the driving part two 3 pushes the transfer compartment 12 to move forward and slide out, the transfer compartment 12 and the baffle 121 will push the lower part of the target leaf to tilt forward during the forward movement, so that the leaf sample can be tilted and laid in the inside of the transfer compartment 12, then the baffle 121 is driven by the motor 122 to rotate reversely by 90 degrees to close the transfer compartment 12, then the two blades 14 start to cut, after the leaf sample is cut off, the driving part two 3 starts to drive the transfer compartment 12 and the baffle 121 to move rightward into the inside of the load compartment 11, the leaf sample moves to the upper part of the collection box 13, then the two blades 14 will be driven to slide into the inside of the load compartment 11.

[0031] In the above embodiment, as shown in Figure 3 and Figure 6 When the transfer compartment 12 and the baffle 121 jointly push the leaf sample into the inside of the load compartment 11, it can be saved, but when the device collects the leaf sample again, the previous leaf sample will also be pushed out by the transfer compartment 12, which will cause the leaf sample collected previously to be blown off by the wind and lost during the subsequent collection of the leaf sample, therefore, in order to solve the technical problem, in the embodiment, the UAV device further comprises a collection box 13 sliding in the inside of the load compartment 11, the front part of the transfer compartment 12 is provided with a telescopic plate 123, the lower part of the telescopic plate 123 is provided with two limit blocks 124 symmetrically distributed, and the limit blocks 124 slide in the middle part of the load compartment 11.

[0032] Specifically, the load compartment 11 is hollow and has a length greater than that of the transfer compartment 12 and the collection box 13, and the width of the three is consistent, the collection box 13 has a semi-closed structure with an upper opening, the length of the collection box 13 is greater than that of the transfer compartment 12, the collection box 13 slides as a whole in the inside of the lower part of the load compartment 11, when the transfer compartment 12 slides completely in the inside of the load compartment 11, the transfer compartment 12 and the collection box 13 can form a continuous space, the telescopic plate 123 has a telescopic structure, the length of the two limit blocks 124 is consistent with that of a single telescopic plate 123, and is greater than the thickness of the front side wall of the load compartment 11, the limit blocks 124 and the telescopic plate 123 at the rear end slide under the action of an external force, and the sliding distance is the length of the limit blocks 124.

[0033] The transport bin 12 can pull the telescopic plate 123 to stretch the lower part of the closed transport bin 12, and the transport bin 12 extrudes the telescopic plate 123 to shrink, and the rear side of the transport bin 12 starts to open and expose the upper part of the collection box 13. When the telescopic plate 123 is fully retracted, the transport bin 12 can push the telescopic plate 123 and the two limiting blocks 124 to move backward, so that the lower part of the transport bin 12 can be fully exposed to the upper part of the collection box 13. When the transport bin 12 is driven by the driving part two 3 to slide into the inside of the load bin 11, the lower part of the transport bin 12 is opened due to the shrinkage of the telescopic plate 123, and the rear end of the leaf sample in the transport bin 12 will first slide into the middle part of the transport bin 12 under the action of gravity. When the transport bin 12 moves subsequently, the leaf sample is slowly pushed into the inside of the collection box 13 by the baffle 121, and the collection order of the leaf sample can be recorded, that is, the stacking order of the leaf sample from bottom to top.

[0034] In the above embodiment, as shown in Figure 3 、 Figure 6 and Figure 9 , since the position of the leaf sample falling after each cutting cannot be guaranteed to be located in the middle part of the transport bin 12, that is, the middle part of the telescopic plate 123, and the surface of the leaf sample is rough, soft and curved, when the leaf sample is pushed backward by the baffle 121 and slides into the lower part of the load bin 11, the leaf sample can not completely enter the inside of the collection box 13, that is, the rear end of the leaf sample is located in the inside of the collection box 13, and the front end of the leaf sample protrudes from the front upper part of the collection box 13. If the sampling operation is performed again at this time, the rear end of the transport bin 12 forms a shearing surface with the front end of the collection box 13 when the transport bin 12 slides forward, which causes the leaf sample to be partially cut, resulting in damage to the integrity of the leaf sample. Therefore, in order to solve the technical problem, the unmanned aerial vehicle device further comprises a guide part 4 for guiding the movement of the leaf sample in the embodiment. The guide part 4 comprises a gas bin 41 arranged at the lower part of the load bin 11, a piston plate 42 slidably connected in the inside of the gas bin 41, a push rod 43 arranged at the front end of the piston plate 42, the rear end of the push rod 43 arranged at the right side of the mounting block 32, a synchronous plate 16 and a spring rod 17 arranged at the rear side of the collection box 13, and the rear end of the spring rod 17 arranged at the inner wall of the load bin 11.

[0035] Specifically, two through holes 15 for exhausting and inhaling are arranged at the rear side of the load bin 11, the spring rod 17 is a prior art which can contract when extruded and rebound when losing pressure, the gas bin 41 is a rectangular cavity, the piston plate 42 can slide in the inside of the gas bin 41, the push rod 43 serves as a structure for driving the piston plate 42 to slide and is connected with the mounting block 32, the reciprocating movement of the mounting block 32 provides power for the sliding of the piston plate 42, the rear side of the gas bin 41 is provided with an exhaust port 44, and the inside of the gas bin 41 communicates with the inside space of the load bin 11 through the exhaust port 44, from which a wide-area airflow can be blown out, and the position arrangement of the leaf sample in the collection box 13 is guided by the airflow.

[0036] When the transport bin 12 is driven by the driving member 3 to move backward, the mounting block 32 can simultaneously push the piston plate 42 to move backward, the piston plate 42 can push the air inside the gas bin 41 to move right and be sprayed from the air outlet 44 into the inside of the load bin 11, when the leaf sample is affected by gravity to droop downward and contact the airflow sprayed from the air outlet 44, the airflow can assist to blow the leaf sample to move backward and support the middle and rear part of the leaf sample, which can effectively avoid the leaf sample to be in contact with the inner wall of the collection box 13 too early, when the transport bin 12 moves backward and the synchronization plate 16 is contacted, the transport bin 12 will push the synchronization plate 16 and the collection box 13 to move backward, at this time, the collection box 13 will move backward with the transport bin 12, the longer space of the front part of the collection box 13 compared with the transport bin 12 is gradually exposed, when the transport bin 12 and the collection box 13 move to the last end, no airflow is sprayed from the air outlet 44, the front end of the leaf sample can fall into the inside of the collection box 13.

[0037] The above-mentioned embodiments only express several embodiments of the present application, the description is more specific and detailed, but it cannot be understood as the limitation of the patent scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which belong to the protection scope of the present application.
