Description

Technical Field

[0001] The utility model relates to the technical field of bird observation, in particular to a camera device used for observing a mandarin duck breeding nest and its egg-laying and hatching behavior. Background Art

[0002] Mandarin duck (Aix galericulata), also known as Mandarin duck in English, belongs to the genus Aix, Anseriformes, Anatidae, and is a national second-level key protected wild animal. Mandarin ducks are mainly distributed in eastern Asia, inhabiting inland lakes and streams. They migrate to their breeding grounds from late March to early April every year, moving in groups in the forest and surrounding rivers and ponds. As the weather gradually warms up, mandarin ducks gradually disperse and enter the nesting site in pairs. They nest in natural tree holes of old trees close to the water, about 10 meters above the ground. The nest material is extremely simple, with sawdust from the tree itself and down feathers shed from the female bird during molting. The size of the tree hole is generally 10 cm × 8 cm, the size of the tree hole is about 40 cm × 30 cm, the wall thickness is 8 cm, and the depth is generally more than 60 cm.

[0003] In the natural state, only old trees can provide suitable natural tree holes as nesting places for mandarin ducks to lay eggs and hatch. In order to solve the problem of insufficient natural tree holes in urban parks, the mandarin duck protection project team of Beijing Zoo provided new nests for mandarin ducks to lay eggs and hatch by hanging artificial nest boxes, and successfully achieved artificial attraction of mandarin ducks. The project team conducted scientific research on the breeding and hatching behavior of mandarin ducks in natural tree holes and artificial nest boxes, and obtained the breeding parameters of mandarin ducks, which is conducive to further research and protection of mandarin ducks. However, because the mandarin duck nests (natural tree holes and artificial nest boxes) are too high from the ground, researchers cannot observe the mandarin ducks in the nests at any time, and climbing tree trunks not only cannot ensure their own safety, but also easily disturbs the mandarin ducks, causing the mandarin ducks to abandon the nest during the hatching period. The existing video observation equipment is expensive, needs to be installed in advance when used, and cannot observe mandarin ducks at any time in the wild without a network.

[0004] Therefore, how to reduce the cost of scientific research, or how to enable researchers to observe mandarin ducks conveniently and effectively at any time in the wild without Internet access, is a goal that the industry urgently needs to improve. Utility Model Content

The camera device includes a telescopic rod 1, a winding drum 14 and a power module 2 are provided on one side near the bottom of the telescopic rod 1. The power module 2 is axially (such as Figure 6 The telescopic rod 1 is installed on one side of the telescopic rod 1 (in the direction shown by the central axis L) and is arranged adjacent to the winding drum 14. A display screen 3 is axially installed on the telescopic rod 1, and the display screen 3 and the power module 2 are symmetrically arranged. A camera unit 4 is installed on the top of the telescopic rod 1, and the camera unit 4 includes a camera 41 and a wire 42. The wire 42 is wound on the winding drum 14, one end of the wire 42 extends upward along the axial direction of the telescopic rod 1 and is connected to the camera 41, and the other end is respectively connected to the power module 2 and the display screen 3. The telescopic rod 1 changes in length by extension. During use, the telescopic rod 1 is extended, and the camera 41 located at the top of the telescopic rod 1 moves accordingly. The camera 41 is connected to the power module 2 and the display screen 3 through the wire 42, which is used in an environment without a signal in the wild. When the telescopic rod 1 is extended, the winding drum 14 is used to reel in and release the wire to make the length of the wire 42 match the extension and retraction distance of the telescopic rod 1, so as to ensure that the picture taken by the camera 41 can be transmitted to the display screen 3 in real time, so as to shoot and observe the mandarin ducks.

[0048] like Figures 2 to 4As shown, the wire 42 includes a power line 421 and a video transmission line 422, one end of the power line 421 and the video transmission line 422 are connected with a junction box 423, the junction box 423 is installed on one side of the top of the telescopic rod 1, the power line 421 and the video transmission line 422 are connected based on the junction box 423 to form a data line 424 connected to the camera unit 4, the junction box 423 is installed on the top of the telescopic rod 1, the power line 421 and the video transmission line 422 are connected to form a data line 424 through the junction box 423, so that a distance from the top of the telescopic rod 1 to the camera 41 is connected through a single data line 424, so as to avoid the problem of being entangled in tree branches due to too many connected lines during shooting.
