Problems solved by technology

Although the structure of the wave suppressor is simple and easy to install, it is actually aimed at the field of underground explosion-proof wave suppression, and the hole diameter on the orifice plate is fixed, and the position of the orifice plate is fixed and placed vertically, which cannot be flexibly used in the technical field involved in the present invention. According to different water depths, wave heights and wavelengths, the best wave suppression effect cannot be achieved.

Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] Such as figure 1 And shown in Fig. 3 (a), Fig. 3 (b), Fig. 3 (c): the present invention comprises orifice plate 1, upper support 4 and lower support 8, orifice plate 1 is installed in the middle of upper support 4 and lower support 4, And the present invention has at least two orifice plates 1 to form a multi-layer orifice plate, and the apertures on each orifice plate are different, and the multi-layer orifice plates are arranged from large to small along the direction facing the waves according to the difference in aperture size. And there is a certain distance between the orifice plate and the orifice plate. The orifice plate 1 is hingedly mounted on the upper bracket 4 and the lower bracket 8, so a living hinge 3 is arranged on the upper bracket 4 and the lower bracket 8, and the living hinge 3 is evenly and symmetrically ...

Abstract

The invention provides a variable damping wave absorbing structure which comprises an upper bracket, a lower bracket and at least two orifice plates arranged between the upper and lower brackets, wherein apertures in the orifice plates are unequal; the orifice plates are arranged from the orifice plates with large apertures to the orifice plates with small apertures. According to the variable damping wave absorbing structure, the apertures of the orifice plates are different, and included angles between the orifice plates and the horizontal plane can be changed to be adapted to different wave lengths and wave heights and different waves, so that the variable damping wave absorbing structure has good variable damping wave absorbing effects, is high in adaptability, and can be widely applied to multiple wave absorbing places.

Description

technical field [0001] The invention relates to a wave-absorbing structure, in particular to a wave-absorbing structure with variable damping. Background technique [0002] At present, the main wave absorbing devices in the tank include arc wave absorbing devices, barbed wire array wave absorbing devices and box type wave absorbing devices. For a tank with a relatively fixed water depth, the arc-shaped wave-absorbing device has a better wave-absorbing effect. However, the radian of the arc at the top of the device remains unchanged, so there is an optimal water depth with the best wave-absorbing effect in the arc-shaped wave-absorbing device. Once the water depth in the water tank deviates greatly from the optimum water depth, the device cannot achieve a good wave suppression effect. For the tank with relatively fixed wavelength and wave height, the barbed wire array wave damping device has a better wave damping effect. In this device, multi-layer barbed wire with the sam...
