A system for measuring water flow in physics teaching

Abstract

The invention discloses a water flow measurement system for physics teaching, comprising a water tank, a communication device is fixedly connected to the inner bottom surface of the water tank, a thick tube is arranged on the front side of the upper surface of the communication device, and the upper surface of the communication device is provided with a thick tube. The rear side is provided with a thin tube, the front end of the upper surface of the water tank is fixedly connected with a supporting threaded rod, the upper surface of the supporting threaded rod is fixedly installed with a horizontal plate, and the outer surface of the supporting threaded rod is threadedly connected with an adjusting nut, The outer surface of the adjusting nut is slidably connected with a U-shaped connecting frame, the outer surface of the U-shaped connecting frame is slidably connected to the outer surface of the supporting threaded rod through a sliding hole, and the rear surface of the U-shaped connecting frame is connected by a connecting rod. A regulating cylinder is fixedly connected, and the lower end of the inner surface of the regulating cylinder is slidably connected to the outer surface of the thick tube through a sealing ring. Intuitiveness.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a water flow measurement system for physics teaching. Background technique [0002] In the process of physics teaching, some physical phenomena are selected to be operated by the experimental equipment, so that the teacher can demonstrate directly and the students can learn intuitively. Among them, the water flow measurement of the connector needs specific demonstration teaching. [0003] However, most of the existing connector water flow measurement experiments use simple connectors to directly inject water for demonstration. The process is relatively simple and the demonstration effect is poor. During the measurement demonstration, only the change of the water level can be seen, but the pressure of the water flow and the display effect cannot be displayed intuitively, and it is not convenient to change the experimental variables to conduct multiple experiments, which...
