Abstract

The invention relates to the technical field of a camera device, and more particularly, to a schlieren cylinder protection apparatus and the schlieren cylinder, comprising: a left baffle plate, a right baffle plate, a left rotation ball screw, a right rotation ball screw, a coupling device, a guide rail, a hand wheel and a servo motor. The bottoms of the left baffle plate and the right baffle plate are provided with a plurality of guide rail sliding blocks distributed uniformly. The guide rail sliding blocks are sleeved on the guide rail. The top parts of the left baffle plate and the right baffle plate are provided with at least one screw sliding block arranged uniformly. The screw sliding block in connection with the left baffle plate is sleeved on the left rotation ball screw; and the screw sliding block in connection with the right baffle plate is sleeved on the right rotation ball screw. According to the invention, through the left baffle plate and the right baffle plate arranged inside the case body and through the transmission mode of the rotation ball screw and the servo motor, the schlieren cylinder protection apparatus can be adjusted freely in the short time within its starting or closing time to meet the requirement of schlieren cylinders of different sizes, especially of the large size on the time.

Description

technical field [0001] The invention relates to the technical field of photographic equipment, in particular to a schlieren tube protection device and a schlieren tube. Background technique [0002] During the wind tunnel test, it is necessary to take photos of the test model in the test section from both sides through the schlieren camera. The wind tunnel test section is directly connected to the schlieren tube. The pressure will change sharply. On the one hand, it will impact the precision equipment placed at both ends of the schlieren tube; on the other hand, it will arouse the impurity particles on the ground, and the high-speed movement will hit the surface of the optical element in the schlieren tube, causing its wear and affecting the imaging quality. In order to prevent the above situation from happening, it is necessary to install a schlieren protection device between the test section and the schlieren cylinder. The existing mature solution is to install high-streng...
