Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a rat ethology experimental device. Background Art

[0002] Y / T maze, open field test, etc. are widely used in animal ethology test methods for testing animal learning and memory, emotional behavior. The Y / T maze judges the learning and memory ability of animals by the alternative selection of different arms by rodents, as well as the number of entries and time. The open field test is a procedure for observing the activities of animals by placing them in a closed planar area, which is divided into squares, and usually measures their activities by counting the number of squares crossed by animals within a given time.

[0003] Before these existing experimental operation devices are operated, an additional camera recording system needs to be installed to record these ethology data, and appropriate lighting needs to be adjusted to facilitate the identification of animal behavior and reduce the stimulation to animals. However, it takes a long time to adjust the camera to the appropriate angle, and it may also cause deviations, displacements of the camera and uneven lighting due to manual adjustment, which affect the experimental data. For example, it may cause low tracking specificity of animals during the test, resulting in inaccurate experimental data results. In addition, after each experiment, the existing experimental operation devices are not easy to clean and process, which will also affect the data of the next experiment.

[0004] Therefore, it is necessary to design a new rat ethology experimental device to solve the above problems. Content of the Utility Model

The shooting component is electrically connected to a control module arranged on the third cover plate, and a touch display screen is arranged on the control module. A bottom plate is slidably arranged in the housing. A plurality of guide rods penetrating the bottom of the housing are arranged at the bottom of the bottom plate. A lead screw is screwed through the bottom of the housing. The top end of the lead screw is rotatably connected to the bottom plate through a rotary joint, and a hand wheel is arranged at the bottom end of the lead screw.

[0007] Based on the above, a water tank for containing cleaning water is arranged at the bottom of the housing. A water pump is arranged outside the water tank. The inlet of the water pump is connected to the drain outlet arranged in the water tank. The outlet of the water pump is connected to a water spray gun through a water supply pipe. A bracket for placing the water spray gun is arranged outside the housing. The water pump is connected to the control module. A sewage outlet is arranged on the side wall of the housing.

[0008] Based on the above, the shooting component includes an infrared induction module, a camera, and a plurality of lamp beads.
