Problems solved by technology

[0002] When the ship is in a moored state, because there is no forward power, under the influence of wave fluctuations, the ship will always be in a state of swinging left and right. This swinging state will have a certain degree of adverse effects on the work and operation of people on the ship.
At present, there is no auxiliary device for ships that can help the ship overcome the situation of swaying from side to side in the mooring state

Embodiment Construction

[0013] The specific implementation manner of the present invention will be described below with reference to the accompanying drawings. Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 Shown: a self-stabilizing auxiliary device for water-jet propelled ships, which includes a rigidly connected left water spray channel 1 and a right water spray channel 2, and the two are arranged axially symmetrically, at the intersection of the two water spray channels There is a trumpet-shaped water inlet 3 connected at the place, and a buoy 4 is also arranged on the water spray channel on the opposite side of the trumpet-shaped water inlet 3. The ends of these two water spray channels are all provided with drain outlets 5 and connecting rods 6, and A left connecting shaft 7 and a right connecting shaft 8 are connected at the junction of the two water spray channels, one end of the two connecting shafts is connected with the buoy 4, and the other end is respectiv...

Abstract

The invention discloses a self-stability auxiliary device for a ship by means of water-jet propulsion, which is characterized by comprising a left water-jet runner and a right water-jet runner which are in axial symmetry, a flared water inlet is communicated at a junction of the two water-jet runners, a float bowl is arranged opposite to the flared water inlet, a water outlet and a connecting rod are arranged at the tail end of each water-jet runner, a left connecting shaft and a right connecting shaft which are linked with the float bowl are further arranged at the junction of the two water-jet runners, a left valve plate and a right valve plate are arranged at the ends of the left connecting shaft and the right connecting shaft respectively, two stop blocks are axially arranged on the upper portions of the left connecting shaft and the right connecting shaft respectively, and a float bowl limit block connected with the float bowl is clamped between the two stop blocks. The self-stability auxiliary device is simple in structure, ingenious in design, low in cost and capable of generating reverse damping when the ship sways, so that sway of the ship is abated, and the ship is stabilized.

Description

technical field [0001] The invention relates to a ship auxiliary device, in particular to a water jet propulsion ship self-stabilizing auxiliary device. Background technique [0002] When the ship is in a moored state, because there is no forward power, under the influence of wave fluctuations, the ship will always be in a state of swinging left and right. This swinging state will have a certain degree of adverse effects on people's work and operation on the ship. . At present, there is no auxiliary device for ships that can help the ship overcome the situation of swinging from side to side under this mooring state. Therefore need a kind of auxiliary device that can solve this problem now. Contents of the invention [0003] The present invention aims to solve the above-mentioned deficiencies in the prior art, and proposes a water spraying device with simple structure, ingenious design and low cost, which can produce reverse damping when the ship is swaying, thereby weake...
