Abstract

The invention relates to hydraulic engineering, in particular, to devices for producing single waves in hydro trays. The purpose of the Invention is to improve the accuracy of wave modeling. Wave Producer contains hydro 1, supports 2, a wave-forming bell 3 connected with drive 4, impellations 5 and frame 6 with rollers 7 in contact with supports 2. Elastic plates are attached to the lower edges of the side 13 and rear 14 walls. material, and the adjacent ends of the plates are interconnected. The plates form a skirt 15. An Il6 plate made of an elastic material is attached to the edge of the front wall of the bell. The bell 3 is lowered, it is filled with water, and the air is vented through the open valve 5. Close the valve 5 and move the bell 3 upwards. Then, the valve 5 is opened, and the water pouring out of the bell 3 creates 1 wave in the flow trap. At the same time, due to the presence of the skirt 15, the flow of water does not create a turbulence on the edges of the walls, and the plate 16 improves the conditions for separation of the wave crest from the bell 3. 2 Il. from 3

The invention relates to hydraulic engineering, in particular, to devices for producing single waves in hydro trays.

The purpose of the invention is to increase the accuracy of wave modeling.

FIG. I shows a wave viewer, side view; figure 2 - section aa in figure 1.

.. A wave producer for receiving single waves contains a hydraulic current 1, guiding supports 2, a wave-forming bell 3 installed in supports with the possibility of vertical movement from the actuator 4. In this case, the bell 3 fs is equipped with a controllable valve 5 located in its upper part and a rigid frame 6 with rollers 7 in contact with supports 2, the upper ends of which are interconnected with transverse beams 8 each along; and drive 4 is fulfilled in the form of a load-lifting reversing mechanism with engine 9 mounted on beams 8 and having

The wave-forming bell 3 under its own weight drops below the water level and is immersed in hydraulic flow 1 strictly vertically, as the wave-forming bell 3 is moved in supports 2 by means of rollers 7 of frame 6 in contact with them (Fig. 1). The control flap 5 is open at the same time, and the air escapes from the bell 3. After the required bell 3 is immersed, the flap 5 closes.

The motor 9 mounted on the beams 8 is turned on, and the actuator 4, by winding the cable 10 connected to frame 6, moves the bell 3 up to the required height, after which the valve 5 opens, water flows out, and a wave is formed in the hydraulic flow. In this case, the skirt 15 will come into contact along the entire length of the walls 13 and 14 with the walls of the hydrojar 1J, which significantly reduces the vortex formation at the diverter 10, associated with the frame 6 (Fig. 1), 75 de water from the bell, plate

16 of the elastic material. The material will take the form of a wave crest (with a full lift of the bell), which satisfies the conditions of the flow around and the crest away from the wall 30 of the bell, and also reduces the vortex formation, as a result of which the wave modeling accuracy.

In addition, the wave-forming bell 3 is installed in the supports with the possibility of moving the lower edge 11, its front wall 12 parallel to the surface of the liquid in hydraulic flow 1, and along the side 13 and rear 14 walls there is a fixed skirt 15, which is a plate of elastic material, which can be in contact with the walls of the hydraulic track 1. On the front wall 12 of the bell 3 a plate 16 of elastic material is fixed, not connected with the edges of the skirt 15. For the elastic material of the skirt and the plate you can, for example, use thin sheets rubber or rubberized fabric, as well as elastomers.
