Embodiment 1

[0028] Such as figure 1 with figure 2 As shown, in Embodiment 1 of the present invention, including a gate plate, a bracket and a lifting device, the gate plate 1 is arranged with elastic materials 2 on the left and right edges, elastic materials 3 are arranged on the bottom edge, and vertically arranged on the front side panel There are several (take two as an example) guide beams 4, and a cable fairlead 5 is installed at the bottom; the support is composed of a transverse support 8 and a transverse support 11 respectively arranged on the front and rear sides of the gate plate 1 and spanning above the water tank; Both the bracket 8 and the transverse bracket 11 are arranged with three fixed pulleys 10 on the top, and there are four conductive fluent strips 18 vertically arranged on the side close to the gate plate 1, and all the conductive fluent strips 18 act on the panel of the gate plate 1 , four conduction fluent strips are arranged in pairs; two space-limiting fluent s...

Embodiment 2

[0032] Such as Image 6 As shown, compared with Embodiment 1, the support also includes a vertical support 21, the vertical support 21 is arranged outside the test water tank, its top is fixed with the horizontal support 8 and the horizontal support 11 at the same time, and four casters 22 are installed at its bottom. The winch 7 of lifting device is installed on the vertical support 21.

Embodiment 3

[0034] In Embodiment 3 of the present invention, the bracket and the lifting device are exactly the same as those in Embodiment 1 or Embodiment 2, but are different on the gate plate, such as Figure 7As shown, the fixing of the elastic material 2 and the panel of the gate plate 1 is strengthened by the cover plate 24, and the cover plate 24 is installed on the gate plate 1 by fasteners 25; the fixing of the elastic material 3 and the panel of the gate plate 1 is carried out by a cover plate 23 For reinforcement, the cover plate 23 is mounted on the gate plate 1 by fasteners 25 .

[0035] In the above embodiment of the present invention, the gate plate 1 adopts a 18mm thick Chevron board, the elastic material 2, the elastic material 3 and the buffer pad 20 all adopt a 3mm thick strong sponge single-sided adhesive tape, and the guide beam 4 adopts a stainless steel angle iron. The cable guide 5 adopts a stainless steel round pipe with a flange seat, the cable 6 adopts a stainle...

Abstract

The invention provides a lifting gate type internal solitary wave generating device comprising a gate sheet, a support and a lifting device; the left and right sides and bottom edge of the gate sheet are provided with elastic material, a panel is vertically provided with a plurality of guide beams, and the bottom is provided with a cable guide; the support comprises two transverse racks respectively arranged in the front and rear side of the gate sheet and crossing above a water groove; a fixed pulley is arranged on the top of each transverse rack; one side, close to the gate sheet, of the transverse rack is vertically provided with a conductive fluent bar, and all conductive fluent bars are applied on the panel of the gate sheet; the transverse rack close to the guide beam is vertically provided with a plurality of limit fluent bars, and all limit fluent bars are applied to the corresponding guide beams; the lifting device comprises a cable and a hoist; the cable penetrates the gate sheet cable guide, and two ends of the cable are commutated by the corresponding fixed pulley and fixed on the hoist; the hoist is arranged on the support and can synchronically pull the two ends of the cable. The lifting gate type internal solitary wave generating device is suitable for large, medium and small test water grooves, simple in structure, and easy in operations.

Description

technical field [0001] The invention relates to a wave making device, in particular to a lifting gate type internal solitary wave making device. Background technique [0002] Internal solitary wave is a kind of fluctuation that occurs in density-stratified seawater, and it exists widely in the ocean. The wavelength of internal solitary waves can reach hundreds of meters to hundreds of kilometers, and the wave amplitude can reach the order of hundreds of meters, which poses a great threat to underwater vehicles and marine engineering equipment. It is a very intuitive and effective research method to conduct physical experiments on internal solitary waves using a density stratified flow test tank, and the generation of internal solitary waves in the test requires the use of suitable wave-making devices; the current wave-making of internal solitary waves The device has structural forms such as lifting gate type, rotating louver type and double push plate type. Among them, the ...
