Abstract

The invention relates to the related technical field of projection equipment, and discloses an intelligent projector for modern teaching and training. The intelligent projector comprises a wall body and a projector, the inner wall of the wall body is provided with a fire-fighting pipe, the inner wall of the wall body is provided with a storage cavity with a downward opening, the side wall of the fire-fighting pipe is in threaded connection with a support frame located in the storage cavity, and a movable plug is movably mounted on the inner wall of the supporting frame, and an adjusting pipe is fixedly connected to the inner wall of the movable plug. The fan blades are arranged in the adjusting pipe and communicated with the inner cavity of the projector through the heat dissipation cavity, so that the pressure of airflow in the inner cavity of the supporting frame is enhanced through rotation of the fan blades, the projector is pushed out, and therefore height adjustment of the projector is achieved; meanwhile, hot airflow blown by the fan blades exchanges temperature with a cold water medium in the fire-fighting pipe; water medium cooling in the projector is realized, the external temperature does not influence heat dissipation of the projector, and finally automatic adjustment of the installation height and water-cooling heat dissipation are realized.

Description

technical field

[0001] The invention relates to the related technical field of projection equipment, in particular to an intelligent projector for modern teaching and training. Background technique

[0002] A projector is a device that magnifies images and videos on a projection cloth, so as to satisfy multiple people for long-distance viewing, so it is widely used in teaching and training rooms, corporate conference rooms, etc.

[0003] When the projector is installed in places such as teaching, because the space on the ground is occupied by students, etc., in order to achieve stable imaging, it is usually fixed to the top of the room by bolts, which solves the problem of stable imaging of the projector. It does not occupy the space on the ground, so it is widely used. However, in the actual use process, because the projector is fixed on the top of the room, when adjusting the imaging position up and down, people need to use ladders to adjust it at high altitude. As a resu...
