Passive optical fiber communication principle teaching experiment box

Abstract

The invention discloses a passive optical fiber communication principle teaching experiment box, which comprises an experiment box body, the bottom of the experiment box body is fixedly connected with a box body support, one end of the box body support is fixedly connected with a water storage tank, the water storage tank is internally provided with a cooling water pipe, the inner side wall of the experiment box body is fixedly connected with a first bearing, the center of the first bearing is rotatably connected with a first rotating shaft, the outer side wall, located in the cooling water pipe, of the first rotating shaft is fixedly sleeved with a third rotating sleeve, the outer side wall of the third rotating sleeve is fixedly connected with a driving water valve, and a communication working circuit is arranged in the experiment box body, the outer side wall of the side, close to the communication working circuit, of the first rotating shaft is fixedly sleeved with a fan rotating sleeve, and the outer side wall of the fan rotating sleeve is fixedly connected with a fan. According to the invention, through arrangement of the cooling water pipe, the fan, the driving water valve and the first rotating shaft, double cooling effects of water cooling and air cooling on the outer surface of the communication working circuit are realized.

Description

technical field [0001] The invention relates to the technical field of teaching the principle of passive optical fiber communication, in particular to a teaching experiment box for the principle of passive optical fiber communication. Background technique [0002] In the teaching process of electronic circuits, in order to facilitate students' learning and understanding, experimental boxes are often used to carry out a large number of circuit experiments to assist teaching. When these experimental boxes are not conducting teaching experiments, the experimental equipment is stored in the storage area. When needed When conducting experiments, teachers or students take the experimental equipment out of the storage area and operate it on the experimental platform. The teaching experiment box can also be provided with a box cover, which closes the teaching experiment box when the experiment is not being performed, so as to facilitate the storage and handling of the teaching exper...
