Flushing apparatus for green water test

Abstract

The invention belongs to the green water test equipment technical field and relates to a flushing apparatus for a green water test. The flushing apparatus includes a flushing device, a square water pipe and a green water test piece; test points on the green water test piece are correspondingly provided with a strain gauge and a displacement meter, wherein the strain gauge and the displacement meter are connected with a computer; one end of the square water pipe is connected with the flushing device, and the other end of the square water pipe is connected with the green water test piece; the flushing device includes a water tank, a lifting table and a flushing valve; the bottom of the water tank is connected with the lifting table; one end of the flushing valve is connected with the water tank through a circular soft joint, and the other end of the flushing valve is connected with the square water pipe; and a plurality of parameters such as water flow impact speed, water flow rate, water flow impact angle, the shape and impact position of impact water flow are adjusted and controlled, so that the dynamic response of water flow impact to a deck can be tested quantitatively. The flushing apparatus of the invention has the advantages of simple structure, operational easiness, good test results, reasonable manufacture and operation costs.

Description

technical field [0001] The invention relates to the technical field of ship deck wave test equipment, in particular to a flushing device for a deck wave test. Background technique [0002] With the development of sea transportation to the deep sea, ships as the carrier of sea transportation have to face the test of various harsh sea conditions. Severe sea waves induced by storms will cause large nonlinear swaying motion of the ship and deck wave impact, which will generate huge deck wave impact pressure on the ship structure. Flatten the hatch cover, collapse the deck of the ship building, destroy the armament on the ship, and deteriorate the stability of the ship. For ships without hatch covers such as inland and offshore transport ships and various small fishing boats, when the waves on the deck are severe, the waves will Influx into the cabin, and even cause the ship to capsize. Generally speaking, there are two situations of waves on the deck: one is that the water bod...

Problems solved by technology

Although this equipment can be used in the laboratory to carry out the wave test on the deck, because the device needs to change the flushing tank frequently to change the flushing water flow, flushing angle and impact force when adjusting the test conditions, the operation is more complicated, and the flushing tank Only one end is hingedly connected with the fixture pier, so it is relatively easy to fall off, so there is still a lot of room for improvement in the existing technology
