Embodiment 1

[0050]This embodiment provides a soap film water hole test device, which can make the flow rate of the soap film water hole test device meet the test requirements of high flow rate, and can effectively control the flow rate.

[0051] Such as figure 2 As shown, the soap film water hole test device comprises: an outer frame 1, an inner frame 2 and a position locking mechanism;

[0052] Wherein the internal frame 2 is the test main device fixed in the external frame 1, and the two opposite ends of the internal frame 2 (such as figure 2 The shown left and right ends) are supported on the external frame 1 by bearings, and can rotate around the bearing axis (horizontal direction). After rotating to a set angle, the position is locked by the position locking mechanism.

[0053] Such as image 3 and Figure 4 As shown, the internal frame 2 includes: a bracket 201, an optical axis seat, a hook, a silk thread 204, an upper water tank 205, a lower water tank 206, a bracket slider 20...

Embodiment 2

[0067] On the basis of the above-mentioned embodiment 1, in order to further increase the flow velocity of the soap film, a thread traction mechanism is added; the thread traction mechanism drives the two silk threads 204 used to form the guide frame to move downward synchronously, thereby assisting in controlling the flow velocity.

[0068] Such as Figure 7 As shown, the thread traction mechanism includes: traction rollers, guide hooks 301, thread convergence buckets 302, traction motors, dampers and winding reels; wherein the traction rollers and silk thread convergence buckets are fixed on the internal frame 2; the connection relationship is: through Two parallel linear slide rails 303 are connected to the optical axis seats at the corresponding positions on the left and right side panels of the internal frame 2, and each linear slide rail 303 is provided with two guide hooks 301 slidingly matched with it, and two silk threads 204 or so After being arranged side by side, t...

Embodiment 3

[0073] On the basis of the above-mentioned embodiment 1 or embodiment 2 or embodiment 3, specifically, the position locking mechanism adopts a spring lock, and a spring lock is provided on the outside of the left and right side plates of the inner frame 2 bracket 201, and the spring lock passes through the corner code (The corner code is a triangular bracket) fixed on the side plate; the position of the spring lock corresponds to the position of the index plate on the outer frame of the corresponding side, and the index plate is provided with a locking hole for matching with the mandrel of the spring lock; it needs to be rotated When the inner frame 2 is in place, pull out the mandrel of the spring lock, and when the inner frame 2 is rotated to the set angle position, insert the mandrel of the spring lock into the locking hole on the index plate, thereby fixing the inner frame 2.

Abstract

The invention provides a soap film water hole test device, which can realize effective control of soap film flow and can adjust test related parameters according to test requirements. The soap film water hole test device includes: an external frame, an internal frame and a position locking mechanism; the left and right ends of the internal frame are supported on the external frame by bearings, and can rotate around the axis of the bearing to change the rotation angle of the internal frame; the position locking mechanism is used After the internal frame is rotated to the set angle, the position of the internal frame is locked; the internal frame includes: brackets, bracket guide rails, wires, upper water tank, lower water tank and mold table; the mold table is used to fix the mold required for the test; the test is adopted The device can adjust the length and position of the test area, change the width of the test area (that is, the width of the soap film), and change the test angle according to the test needs; thus construct two-dimensional water tunnels with different parameters to adapt to different models; and can change the flow field velocity.

Description

technical field [0001] The invention relates to a test device, in particular to a soap film water hole test device. Background technique [0002] There are a large number of surfactant molecules in the soap film, so its surface tension is only about one-third of that of water, making it easier for the soap liquid to be pulled apart to form a film. In 1981, Couder first used soap film as an experimental method to simulate the flow structure of a two-dimensional drag pool, and then a series of experimental studies used soap film to simulate two-dimensional flow field. The display of the flow structure of the two-dimensional flow field of the soap film is realized through the colored stripes on the soap film, and the light irradiated on the surface of the soap film is reflected on the gas-liquid interface between the soap film and air. The wavelength of visible light is comparable in magnitude, and the light emitted on the film interferes with each other to form fringes. These...
