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] Specific embodiments of the present invention will be described below with reference to the accompanying drawings. like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 Shown: A self-stabilizing auxiliary device for water jet propulsion ships, which includes a left water jet channel 1 and a right water jet channel 2 that are rigidly connected, and the two are arranged axially symmetrically, at the intersection of the two water jet channels There is a horn-shaped water inlet 3 connected at the place, and a buoy 4 is also provided on the water jet channel on the opposite side of the horn-shaped water inlet 3. The ends of these two water jet channels are provided with a water outlet 5 and a connecting rod 6, and A left connecting shaft 7 and a right connecting shaft 8 are also threaded through the connection of the two water spray channels. One end of the two connecting shafts is connected to the buoy 4, and the other end is provided with a left valv...

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 at berth, because there is no forward power, under the influence of wave fluctuations, the ship will always be in a state of left and right swaying. This swaying state will have a certain degree of adverse impact on people's work and operations on the ship. . At present, there is no auxiliary device for ships that can help the ship to overcome this situation of swaying left and right in the berthing state. Therefore, there is a need for an auxiliary device that can solve this problem. SUMMARY OF THE INVENTION [0003] In order to solve the above-mentioned shortcomings of the prior art, the present invention proposes a water spray with simple structure, ingenious design and low cost, which can generate reverse damping when the ship is swaying, thereby weakening the swaying mo...
