Rotary diving platform experimental device capable of automatically recording and with variable speeds

Abstract

Provided is a rotary diving platform experimental device capable of automatically recording and with variable speeds. The bottom end of a main rotary shaft is arranged in a funnel and connected with a driving device, and the driving device is connected with a controller; a ball crown-shaped diving platform which is used for the grip of a mouse is fixed on the top end of the main rotary shaft, the main rotary shaft is provided with a speed measuring device for measuring the speed of the main rotary shaft, and the speed measuring device comprises a speed measuring turntable fixedly arranged on the main rotary shaft coaxially and a Hall sensor fixedly arranged on one side of the main rotary shaft; a speed measuring magnetic block is fixed on the speed measuring turntable, and the Hall sensor and the speed measuring magnetic block are opposite to each other and matched with each other; the distance between the Hall sensor and the main rotary shaft is equal to that between the speed measuring magnetic block and the main rotary shaft, and the Hall sensor is connected with the controller; a monitoring device is arranged at the small opening of the funnel and used for detecting whether or not the mouse falls down, and the monitoring device comprises a plurality of pairs of infrared radiation sensors arranged on the inner wall of the funnel; each pair of the infrared radiation sensors are connected with the controller, and a timer is arranged inside the controller.

Description

technical field [0001] The invention relates to an automatic recording and variable speed rotating platform experiment device. Background technique [0002] The experimental mice do unsupported passive rotation on a rotating platform, and observe the persistence of the passive rotation of the mice at different speeds. This experiment can be considered to belong to the anti-fatigue or anti-vertigo experiment of mice (see Gerning, Yuan Yong, Ying Huazhong, etc. Development of data memory animal fatigue tester [J].

[0002] Experimental mice do unsupported passive rotation on a rotating platform, and observe the persistence of passive rotation of mice at different rotational speeds. This experiment can be considered to belong to the anti-fatigue or anti-vertigo experiment of mice (see Gurning, Yuan Yong, Ying Huazhong, etc. Development of data memory animal fatigue tester [J].

Chinese Journal of Comparative Medicine, 2014, 24(7): 77-80.), which can be used in the research and development of anti-fatigue drugs, anti-vertigo drugs, antidepressant drugs, and stimulant drugs. In the experimental research related to medicine and aerospace, but there is no such device on the market that can automatically record
