Description

Technical Field

[0001] This invention relates to the field of animal capture technology, specifically a harmless trapping device for crane rescue. Background Technology

[0002] Cranes need to migrate in winter, and they often get injured during the migration, most commonly with wing injuries that prevent them from flying. When a crane cannot continue its migration, it needs to be rescued. The first step in the rescue is to capture the crane and then treat its injured area. Cranes are easily frightened when rescuers approach, struggling in their hands or moving away from them. To avoid harming the crane during the capture process, it is difficult to hold it firmly when it struggles, requiring multiple attempts to capture it successfully. This increases the difficulty of the crane rescue and may delay the treatment of the crane's injured area.

[0003] A search revealed that patent application number CN202011343117.1 discloses an animal trapping rod that uses a feeding component to lure and capture animals from a distance based on their habits. After an animal enters the trapping area, a person can remotely control the toothed trapping pincers to capture the animal by pulling the handle switch.

[0004] However, the aforementioned capture clamps cannot control the squeezing force when grabbing animals, and they are not well adapted to animals of different sizes. The larger the animal, the stronger the pressure, which can easily cause greater damage to larger cranes. Moreover, the capture clamps can easily squeeze the injured parts of the cranes, causing secondary damage. Therefore, there is a need for a device that can adapt to cranes of different sizes and reduce the damage to cranes during the capture process. Summary of the Invention

[0030] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0031] Example 1

[0032] Figures 1-6 In one embodiment of the present invention, a non-harmful trapping device for crane rescue includes a mobile platform 1 with anti-slip ridges on its top. A capture frame 2, which gradually narrows internally, is fixedly connected to one side of the mobile platform 1. Rollers are installed at the bottom of both the mobile platform 1 and the capture frame 2. A push rod 3 is fixedly connected to one side of the capture frame 2. Multiple positioning components 4 are installed at equal intervals inside the capture frame 2. A sliding plate 5 is slidably connected to the top of the capture frame 2. An induction component 6 and a neck limiting component 7 are installed on the top of the sliding plate 5. By holding the push rod 3, the mobile platform 1 and the capture frame 2 are moved to the injured crane. Nearby, the food on the guiding component 6 attracts the cranes to the mobile platform 1. After the cranes' heads and necks pass through the neck limiting component 7, they come into contact with the food on the guiding component 6. Then, the cranes slide along the mobile platform 1 into the capture frame 2. Inside the capture frame 2, which gradually narrows, the cranes get stuck and stop moving. The staff moves the trapping device and the cranes inside to a safe location. Then, the cranes inside the capture frame 2 are taken out for rescue. The device can trap the cranes in the corresponding positions in the capture frame 2 according to their size, adapting to cranes of different sizes and reducing the damage caused by squeezing the cranes during the capture process.

[0033] The positioning component 4 includes a swing plate 41 rotatably connected to the bottom of the capture frame 2. Both ends of the bottom of the capture frame 2 are slidably connected to folded frames 42 to prevent the swing plate 41 from descending. A crossbar 43, extending movably into the interior of the capture frame 2, is provided on one side of the folded frame 42. An elastic arc plate 44 is fixedly connected to one end of the crossbar 43. A limiting frame 45, used to limit the falling height of the swing plate 41, is fixedly connected to the bottom of the capture frame 2. After the crane enters the capture frame 2, it slides along the inner bottom of the capture frame 2. When the crane shifts to one side inside the capture frame 2, it presses and bends the elastic arc plate 44 on one side of the capture frame 2, pushing the crossbar 43 and the folded frame 42 to move until the folded frame 42 moves to the outside of the capture frame 2 and no longer supports the swing plate 41 from the bottom. At this point, the swing plate 41 is captured. The folded frame 42 on the other side of the capture frame 2 blocks the swing plate 41 from rotating downwards. Only when the crane moves to a position inside the capture frame 2 with a width similar to that of the crane will the crane squeeze the elastic arc plates 44 on both sides, pushing the folded frames 42 on both sides of the capture frame 2 to move to the outside of the capture frame 2 and no longer support the swing plate 41. At this time, the swing plate 41 rotates downwards, and finally the limiting frame 45 at the bottom of the swing plate 41 supports it in a horizontal position. The crane stays on the horizontal swing plate 41 and is restricted in its position and cannot move, waiting for rescuers to arrive for rescue. This can reduce the risk of the positioning component 4 being accidentally activated due to the crane struggling during the capture process, and ensure that the crane is captured in a position with a size similar to its own. This increases the tightness of the crane's restraint without squeezing the crane and causing injury, and reduces the possibility of the crane struggling to escape.

[0034] The induction component 6 includes a support rod 61 that is slidably connected to the top of the slide plate 5. The top of the support rod 61 is fixedly connected to the outer frame 62. A feeding frame 63 is rotatably connected between the two sides of the inner wall of the outer frame 62. A columnar food 64 is installed inside the feeding frame 63. The food that cranes like to eat is made into a columnar shape and placed inside the feeding frame 63. The cranes are lured by the columnar food 64 inside the feeding frame 63 to move to the moving platform 1, and then slide along the moving platform 1 into the capture frame 2 to be captured. The difficulty of capturing cranes is reduced by using food as bait.

[0035] Example 2

[0036] Reference Figures 1-9Based on Embodiment 1, the neck limiting component 7 includes an inclined rod 71 fixedly connected to the top of the slide plate 5. A semi-circular frame 72 is fixedly connected to the top of the inclined rod 71. A semi-circular plate 73 extending to the outside of the semi-circular frame 72 is slidably connected inside the semi-circular frame 72. Both sides of the semi-circular plate 73 are equipped with toothed components 74 to limit its unidirectional sliding along the semi-circular frame 72. After the crane's head and neck pass through the semi-circular frame 72 and the semi-circular plate 73, they come into contact with the columnar food 64 to eat. When the crane slides along the moving platform 1 into the capture frame 2, its neck is encircled by the semi-circular frame 72 and the semi-circular plate 73, thus limiting the crane's body and neck. This reduces the possibility of the crane escaping after being captured. At the same time, fixing at multiple positions reduces the strength required for fixing at a single position, reduces the pressure on the crane's body when captured, and reduces the injury to the crane.

[0037] The toothed assembly 74 includes a storage groove on the outer side of the semi-ring plate 73. A locking plate 741 is rotatably connected to one side of the inner wall of the storage groove. An elastic plastic sheet 742 is fixedly connected between the locking plate 741 and the inner wall of the storage groove. Multiple slots are provided on both sides of the inner wall of the semi-ring frame 72. A traction rope 8 is fixedly connected between the semi-ring plate 73 and the outer frame 62. A limiting ring 9 for guiding the movement path of the traction rope 8 is fixedly connected to the outer side of the semi-ring frame 72. A baffle 10 is fixedly connected to the top of the slide plate 5. A first spring 11 is fixedly connected between the baffle 10 and the support rod 61. When the crane eats the columnar food 64, the columnar food 64 will be pushed by the crane, causing the outer frame 62 and the support rod 61 to squeeze and contract the first spring 11 and slide along the slide plate 5. The volume of the columnar food 64 exposed outside the feeding frame 63 gradually decreases. If the crane wants to continue eating, it needs to get closer to the moving platform 1, and its head and neck need to pass through more of the semi-ring frame 72 and the semi-ring plate 74. 3. Finally, the cranes are guided to the mobile platform 1 and then slide along it into the capture frame 2 to be captured. The capture process is gradual, guiding the cranes to walk onto the mobile platform 1 while feeding, and then slide into the capture frame 2 to be captured. This reduces the cranes' wariness during the capture process. As the cranes push and compress the first spring 11 on the outer frame 62 and the support rod 61, the outer frame 62 pulls the traction rope 8 to move, which in turn pulls the semi-ring plate 73 towards the semi-ring frame 72. The space between the semi-ring plate 73 and the semi-ring frame 72 gradually decreases until the semi-ring plate 73 and the semi-ring frame 72 compress the crane's neck from both sides. At this point, the cranes will not push the outer frame 62 to continue to drive the semi-ring plate 73 and the semi-ring frame 72 to increase the pressure on the neck. The size of the enclosure around the neck can be automatically adjusted by the cranes' feeding process to ensure that the neck limiting component 7 fits tightly to the neck, improving the fit of the enclosure around the crane's neck.

[0038] The skateboard 5 has grooves on both sides, and an elastic plate 12 extending to the outside is fixedly connected to one side of the inner wall of the groove. The inner wall of the capture frame 2 has limit grooves on both sides. When the crane slides along the capture frame 2, the crane's neck pushes the induction component 6, the neck limit component 7 and the skateboard 5, squeezing and bending the elastic plate 12 into the groove of the skateboard 5, and then the skateboard 5 slides along the capture frame 2.

[0039] A counterweight 13 is fixedly connected to the top inner side of the feeding frame 63. A longitudinal plate 14 extending to the outside of the outer frame 62 is fixedly connected to the top of the feeding frame 63. One end of the rotating shaft of the feeding frame 63 extends to the outside of the outer frame 62 and is fixedly connected to a knob 15. When the sliding plate 5 is pushed by the crane to slide along the capture frame 2, the longitudinal plate 14 is pushed by the reaction force of the air, causing the feeding frame 63 to rotate. At this time, the counterweight 13 moves to one side and causes the feeding frame 63 to continue to rotate until the counterweight 13 moves to the bottom of the feeding frame 63. The longitudinal plate 14 on one side of the feeding frame 63 is then... The outer frame 62 blocks further movement. After the feeding box 63 rotates to the outside of the outer frame 62, it covers the cylindrical food 64. At this time, the cranes can no longer eat the cylindrical food 64. When the rescuers come, they turn the knob 15 to make the feeding box 63 rotate until the cylindrical food 64 is exposed after the feeding box 63 rotates. The cranes can then continue to eat. After the cranes are captured, the food can be automatically retracted to prevent the cranes from eating. When the rescuers arrive, they take out the cylindrical food 64 to help the cranes continue to eat. By feeding the cranes, the rescuers can build a closer relationship with the cranes and reduce the difficulty of rescuing them.

[0040] A rocker arm 16 is rotatably connected to the top of the mobile platform 1. A second spring 17 is fixedly connected between the bottom of the rocker arm 16 and the mobile platform 1. When the crane walks onto the rocker arm 16 to eat the columnar food 64, the rocker arm 16 is squeezed and rotates downward, squeezing and contracting the second spring 17. Then the crane slides along the inclined rocker arm 16 into the capture frame 2 and is captured.
