Description

technical field

The utility model belongs to the technical field of pneumatic transmission control, and relates to an automatic lifting gate control device, which is used for fluid-related barrier wave-making experiments.

Background technique

At present, in the wave-making experiments under the conditions of the fluid mechanics laboratory, the requirements for the lifting speed and position accuracy of the ram are very high. But at present, in actual experiments, manual plugging and unplugging is often used. Due to the relatively heavy weight of the ram, at least two people need to pull and plug it hard on both sides at the same time, which will cause inconsistent strength when the ram is pulled out. As a result, the speed and accuracy are affected, thereby affecting the experimental effect. Therefore, based on the above status quo, it is of obvious practical value to study a new type of gate control device that uses pneumatic transmission control technology to automatically adjust and control the lift of the gate, with adjustable lift speed, accurate lift position, low cost and simple operation.
