Description

Technical Field

[0001] The present invention relates to the technical field of field intelligent monitoring, and particularly relates to an infrared camera device for intelligently monitoring and tracking wild animals in the wild. Background Art

[0002] Currently, when intelligently monitoring animals in the wild, infrared cameras are used. However, the horizontal / vertical rotation range of the pan-tilt of traditional infrared cameras is limited. Using a single-axis bracket results in a vertical viewing angle of only ±45°. When tracking the whereabouts of animals, it is unable to cope with the rapid movement of animals in three-dimensional space, resulting in a decline in shooting and monitoring effects. In addition, the complex terrain in forest areas easily causes the equipment to fall over. At the same time, traditional infrared cameras rely on lithium batteries or need to replace batteries regularly, and the battery life is limited in extreme environments. Therefore, we propose an infrared camera device for intelligently monitoring and tracking wild animals to solve the above problems. Summary of the Invention

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

A lifting mechanism is connected to the upper end of the moving plate. A bearing plate is installed at the upper end of the lifting mechanism. A plurality of movable brackets are inserted at equal intervals at the upper end of the bearing plate. A protective box is installed at the upper end of the movable bracket. A rotating mechanism is arranged in the protective box. An adjusting mechanism is installed on the rotating mechanism. An infrared imaging device body is installed on the adjusting mechanism. A solar power generation mechanism is arranged on one side of the protective box.

[0006] Preferably, the walking mechanism includes mounting frames fixed on both sides of the moving plate. Rollers are rotatably connected to both sides of the mounting frames. Guide rods penetrate through both sides of the mounting frames.

[0007] Preferably, the lifting mechanism includes a stud screwed onto the middle of the moving plate. The upper ends of the four guide rods are jointly fixed at the four corners of the lower end of the bearing plate. A connection box is fixed in the middle of the lower end of the bearing plate. A fixing plate is fixed on one side of the lower end of the bearing plate. A rotating rod is rotatably sleeved on the side walls of the fixing plate and the connection box. A second bevel gear is fixed at one end of the rotating rod. A runner is fixed at the other end of the rotating rod. The upper end of the screw rod is rotatably sleeved on the lower side wall of the connection box. A first bevel gear is fixedly sleeved on the upper end of the screw rod, and the first bevel gear and the second bevel gear mesh with each other.

[0008] Preferably, the movable support includes three separately arranged electric telescopic rods. The upper ends of the electric telescopic rods are rotatably connected with universal joint balls. A connecting block is connected between the three universal joint balls, and the upper end of the connecting block is fixed to the lower end of the protection box.

The end of the output shaft of the third servo motor is connected with a gear set, and the upper end of the gear set is connected with a rotating seat. The upper end of the rotating seat penetrates through the side wall of the protection box and extends to the upper end of the protection box.

[0011] Preferably, the adjusting mechanism includes a support seat fixed to the upper end of the rotating seat. A rotating arm is rotatably connected to the support seat. A second servo motor is installed on one side of the support seat. The output shaft of the second servo motor penetrates through the side wall of the support seat and is connected to one side of the rotating arm. The infrared camera device body is rotatably connected to the upper end of the rotating arm. A first servo motor is installed on one side of the rotating arm. The output shaft of the first servo motor penetrates through the side wall of the rotating arm and is connected to one end of the infrared camera device body.

[0013] Preferably, a camouflage coating is coated on the outer side wall of the periphery of the flexible curved photovoltaic panel.

[0014] Preferably, a ground nail is screwed in the threaded blind hole.

[0015] In the present invention, after the three electric telescopic rod supports are unfolded, the movable legs adjust their lengths according to the lidar data (sampling rate 100Hz) so that the equipment center of gravity error ≤ 3mm. When the target is locked, the thermal imaging module detects the animal, and the three servo motors drive the infrared camera device body 7 to perform dynamic adjustment in combination with the adjustment of the electric telescopic rods to make them always correspond, and it can automatically move according to the shooting object, with a minimum focusing distance of 0.5m;

At the same time, the height and position can be adjusted according to needs, improving the flexibility and convenience of monitoring, and also enhancing the comprehensiveness of monitoring.

[0018] The present invention has the following advantages:

[0019] 1. Through the combination of horizontal / vertical rotation and multi-angle telescopic adjustment, the adjustment range is expanded by 270% compared with traditional pan-tilt heads, and the three-dimensional space coverage rate reaches 98%, greatly improving the tracking range;

[0020] 2. Through the telescopic adjustment bracket, the device can work stably on terrains with a slope ≤ 35°, and the wind resistance level reaches level 9, improving the environmental adaptability;

[0022] 4. Through the low reflection characteristics of the curved surface photovoltaic of the flexible curved photovoltaic panel, it avoids disturbing wild animals that are active at night. The camouflage coating, curved surface photovoltaic structure are integrated with the surrounding vegetation form, reducing the visibility of the device. At the same time, it can receive sunlight from more angular positions during the day;

[0023] In summary, through the collaborative design of the four-degree-of-freedom transmission system, three-stage telescopic movable bracket and modular flexible curved photovoltaic panel, the present invention breaks through the bottlenecks of limited perspective and poor environmental adaptability of traditional devices, provides high-precision three-dimensional motion trajectory data for wildlife ethology research.
