Damping net tensioner

Abstract

The invention relates to the technical field of flow field test, and provides a damping net tensioning device. The device comprises a first clamp ring and a second clamp ring which is coaxial with the first clamp ring; a ring-shaped bulge is circumferentially arranged on one side, opposite to the second clamp ring, of the first clamp in an extension manner; a ring-shaped groove is formed in one side, opposite to the first clamp ring, of the second clamp ring in an extension manner; the ring-shaped bulge is matched with the ring-shaped groove in a pluggable manner; a fixing structure is arranged on the first clamp ring or the second clamp ring and located outside the ring-shaped bulge and the ring-shaped groove; the fixing structure is used for fixing the edge of a tensioned net; elastic components are alternately arranged between the first clamp ring and the second clamp ring; a clamping structure is connected between the first clamp ring and the second clamp ring. Through adjusting the clamping force of the clamping structure, the adjustment of the dragging degree of the tensioned net is realized, so that the adjustment of the tensioning degree of the tensioned net is realized; according to the device, a hole does not need to be formed in a rectification section, so that no sealing problem exists and the mounting is convenient.

Description

technical field [0001] The invention relates to the technical field of flow field testing, in particular to a damping net tensioning device. Background technique [0002] In the flow field test of a small-sized channel, the incoming air flow is very turbulent, and the velocity distribution of the flow field is very uneven. In order to study the flow effect under the condition of a uniform flow field, it is usually necessary to rectify the incoming flow. One of the main devices for rectification is the damping net. Let the incoming flow pass through the tensioned damping net to achieve the effect of rectification, and the tension of the damping net has an important impact on the uniformity of the flow field. [0003] The existing fixing structure of the damping net mainly includes a fixed device and an elastic connection device. The fixed connection method is to directly fix the damping net on the cylinder body of the rectification section, which has the problem that the ten...

Problems solved by technology

The fixed connection method is to directly fix the damping net on the cylinder body of the rectification section, which has the problem that the tension of the damping net cannot be adjusted and the flow cannot be controlled; the elastic connection needs to open holes in the rectification section, and there is a seal in the rectification section.
