Description

Technical Field

[0001] This invention relates to the field of navigation early warning equipment technology, specifically to a navigation early warning device that uses infrasound to drive away wild animals. Background Technology

[0002] With increasing global awareness of forest resource protection and national emphasis on ecosystem health, the frequency and intensity of forest patrols are constantly increasing. Modern technologies such as drone patrols, unmanned vehicle monitoring, and automatic early warning systems are widely used in forest fire prevention, illegal logging prevention, and protection of rare species to ensure the stability and health of forest ecosystems. During patrols of target protected areas, which are typically key ecological areas or artificially restored forests, the vegetation, facilities, and ecological structures are relatively fragile and highly susceptible to the impact of wildlife activities. For example, the digging, gnawing, or trampling of seedlings by certain animals can cause serious damage to the vegetation in the protected area and affect the ecological restoration process. Monitoring and timely dispersal of wildlife around the protected area using unmanned monitoring equipment has become a necessary measure. However, this dispersal measure based on unmanned equipment has certain limitations: when the unmanned equipment leaves a specific area, its dispersal effect immediately weakens or even disappears, causing wildlife to quickly return to their original location and continue to pose a potential threat to the protected area. Summary of the Invention

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1 Please see Figure 1 and Figure 2A navigational warning device that uses infrasound to drive away wild animals includes: a drone 1, which is a UAV; a mounting base 7 is installed on the bottom of the drone 1; a warning device 2, a sound wave generating device 3, a controller 4, and a monitoring device 6 are installed on the mounting base 7; the warning device 2 can be an alarm; the sound wave generating device 3 is a device that can emit infrasound, such as an infrasound generator; the controller 4 is a PLC controller; and the monitoring device 6 can be an image recognition camera, an infrared thermal sensor, a lidar, or other equipment used to monitor wild animals (using the above equipment to monitor wild animals is existing technology and will not be described in detail here).

[0018] Please see Figure 2 The mounting base 7 has a placement component 5 installed on its side wall; Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The placement assembly 5 includes a placement box 501, driving members 510, a mounting assembly, and a pushing assembly. Several driving members 510 are arranged horizontally in sequence within the inner cavity of the placement box 501. The pushing assembly includes a push plate 508 and an elastic member 509 (spring). The push plate 508 is slidably mounted within the inner cavity of the placement box 501, and the elastic member 509 is installed between the push plate 508 and the placement box 501. The push plate 508 is in contact with the side wall of one driving member 510, and the elastic force provided by the elastic member 509 causes the push plate 508 to press several driving members 510 together. An opening 50 is provided on the top wall of the placement box 501. 4. An outlet 514 is provided on the bottom wall of the placement box 501. The outlet 514 is located directly below the opening 504. A door panel 512 is hinged to the inner cavity of the outlet 514 via an elastic pivot (the elastic pivot refers to a spring hinge, specifically including the pivot and the spring on the pivot). The pushing assembly includes a driving component 502 located on the top of the placement box 501 and a fixing component 503 located on the moving end of the driving component 502. The driving component 502 can be an electric telescopic rod. The fixing component 503 includes a mounting plate and an electromagnet located at the bottom of the mounting plate (the electromagnet can also be replaced with a vacuum adsorption device). The fixing component 503 is located directly above the opening 504.

[0019] Working principle: The aircraft 1 flies through the forest, patrolling the target protected area. During this process, the monitoring device 6 monitors the surroundings. When the monitoring device 6 detects wild animals, the controller 4 controls the sound wave generator 3 to emit infrasound waves to drive away the wild animals. At the same time, the alarm device 2 also sounds an alarm. The controller 4 then controls the aircraft 1 to descend to the ground (the area where wild animals were detected). Next, the controller controls the drive component 502 to move the fixing component 503 downwards, so that the fixing component 503 passes through the opening 504 and enters the inner cavity of the placement box 501, making contact with the top of a driving component 510 (which is fixed to the fixing component 503). The drive component 502 continues to move downwards with the fixing component 503, so that the fixed component 503... The driving component 510 moves downward, applying downward pressure to the door panel 512, pushing the door panel 512 downward and opening the outlet 514. The driving component 510 continues to move downward until it is inserted into the soil. Then, the fixing component 503 releases the driving component 510, and the driving component 502 moves the fixing component 503 upward to reset. When one driving component 510 is removed from the inner cavity of the placement box 501, the elastic component 509 pushes the push plate 508 to move, so that the remaining driving components 510 inside the placement box 501 are pressed again (i.e., there are driving components 510 below the fixing component 503). The driving component 510 inserted into the ground can continuously drive away the surrounding wild animals. After the installation of the driving component 510 is completed, the controller 4 controls the vehicle 1 to rise and continue patrolling.

[0020] It should be noted that if no wild animals approach the target protected area for a period of time, the repellent device 510 can be retrieved.

[0021] It should also be noted that the placement box 501 consists of a box body and a box cover. The box cover and the box body are connected together by bolts. The box body consists of two shell parts that are interlocked, allowing the interior of the placement box 501 to be opened.

[0022] In this embodiment, as a further optimization, please refer to... Figure 5 and Figure 10 The deterrent device 510 includes a fixed stake 5101, a sound-generating device 5104 (such as an infrasound generator, a small device) disposed on the top of the fixed stake 5101, and a cover 5103 disposed on the top of the fixed stake 5101, the cover 5103 covering the sound-generating device 5104; the sound-generating device 5104 emits infrasound waves to deter wild animals; the cover 5103 is made of a metal that can be magnetically attracted, so that the fixed device 503 can attract and fix the deterrent device 510.

[0023] It should be noted that a detector 5102 (a device for detecting wild animals, such as an image recognition camera) is installed on the fixed stake 5101, and a control device (such as a PLC) is installed on the fixed stake 5101; when the detector 5102 detects wild animals in the vicinity, the control device controls the sound-emitting device 5104 to start, which is used to drive away wild animals and prevent the sound-emitting device 5104 from working continuously; a battery is installed inside the fixed stake 5101 to power the electrical equipment inside the driving device 510.

[0024] In this embodiment, as a further optimization, please refer to... Figure 5 and Figure 6 The cross-sectional length of the outlet 514 is greater than the cross-sectional length of the door panel 512, so that the door panel 512 will not pass through the outlet 514 upwards. A second magnetic block 513 is installed at the top of the inner cavity of the outlet 514. The door panel 512 is made of a metal material that can be magnetically attracted, such as iron, to attract the door panel 512 and fix the door panel 512 so that it will not easily rotate downwards and open the outlet 514.

[0025] In this embodiment, as a further optimization, please refer to... Figure 5 and Figure 7 The bottom of the placement box 501 is provided with a first magnetic block 511, and the top of the door panel 512 is provided with a kit 515. A movable block 516 is slidably provided in the inner cavity of the kit 515. When the door panel 512 is in a horizontal state, the movable block 516 can move up and down at the kit 515. A guide groove 517 is provided on the top of the door panel 512, and the guide groove 517 communicates with the inner cavity of the kit 515. A ball 518 is provided in the guide groove 517. When the door panel 512 is pushed downward by the driving member 510, the first magnetic block 511 attracts and fixes the door panel 512, so that the door panel... 512 will not obstruct the downward movement of the driving component 510, nor will it prevent the fixing component 503 from moving upward and resetting. The door panel 512, attracted by the first magnetic block 511, is in a vertical state. At this time, the rolling ball 518 enters the inner cavity of the kit 515 under the action of gravity, which is used to push the movable block 516 to move to the outside of the kit 515, so that when the fixing component 503 moves upward, it can contact the movable block 516, which is used to pull the door panel 512 to rotate upward, release the attraction force of the first magnetic block 511 on the door panel 512, and allow the door panel 512 to rotate upward and reset under the action of the elastic rotating shaft.

[0026] Example 2 As a further optimization of Example 1, please refer to Figure 3 , Figure 4 , Figure 8 and Figure 9The top of the placement box 501 is provided with a support plate 505. A movable groove 519 is opened on the side wall of the support plate 505. A movable block 520 is slidably arranged in the inner cavity of the movable groove 519. A limiting baffle 506 is provided at the end of the movable block 520 away from the support plate 505. A support plate 507 is provided on the limiting baffle 506. The bottom of the support plate 507 is in contact with the top of the fixing member 503. When the fixing member 503 moves down and pushes the driving member 510 inside the placement box 501 downward, the support plate 507 loses its supporting force and is subjected to gravity. The limiting baffle 506 moves down and inserts into the placement box 501 to block the movement of the remaining driving member 510 inside the placement box 501. When the driving member 502 moves up and resets the fixing member 503, the fixing member 503 contacts the support plate 507 and moves it up, so that the limiting baffle 506 does not contact the driving member 510, thereby releasing the restriction on the driving member 510. This ensures that the driving member 510 inside the placement box 501 can only move after the fixing member 503 is reset, avoiding premature movement that would hinder the reset of the fixing member 503.

[0027] In this embodiment, as a further optimization, please refer to... Figure 8 and Figure 9 The moving groove 519 includes an inclined groove 5191 and a vertical groove 5192. The inclined groove 5191 slopes downward at the end facing the driving member 510, and the vertical groove 5192 is located at the end of the inclined groove 5191 facing the driving member 510. During the upward movement of the fixing member 503 carrying the support plate 507, the moving block 520 slides inside the inclined groove 5191, causing the limiting baffle 506 to move obliquely upward (the limiting baffle 506 moves away from the driving member 510). During this process, the remaining driving member 510 inside the placement box 501 is pushed and moved by the push plate 508 (i.e., the limiting baffle 506 is not completely moved). When resetting, the driving member 510 starts to move, so that the limiting baffle 506 is no longer in contact with the driving member 510. This reduces the stroke that the driving member 510 still needs to move, thus reducing the probability of the driving member 510 colliding under the push of the push plate 508. The inner wall of the inclined groove 5191 is provided with several limiting blocks 521 arranged sequentially along the length of the inclined groove 5191. The limiting blocks 521 are used to increase the resistance of the moving block 520 moving away from the driving member 510, thereby reducing the speed of the driving member 510 and further reducing the probability of the driving member 510 colliding under the push of the push plate 508.

[0028] It should be noted that when the fixing member 503 moves down and does not contact the support plate 507, the moving block 520 is in the inner cavity of the vertical groove 5192. At this time, the limiting baffle 506 will not move when subjected to a horizontal force, ensuring that the limiting baffle 506 will not fail to restrict the driving member 510.

[0029] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
