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
The present invention relates to a kind of boats and ships auxiliary device, particularly a kind of self-stability auxiliary device for ship by means of water-jet propulsion.
Background technology
When boats and ships are in parked state, due to without any the power advanced, under the influence of fluctuations of wave, under boats and ships can be in wigwag motion state all the time, the work of this state people waved on boats and ships and operate the adverse effect all produced to a certain degree.Also do not have at present a kind of auxiliary device of boats and ships can help wiggly situation under this parked state of boats and ships customer service.Therefore now a kind of auxiliary device that can address this problem is needed.
Summary of the invention
The present invention is the above-mentioned deficiency in order to solve existing for prior art, proposes a kind of structure simple, designs ingenious, with low cost, reverse damping can be produced when Ship Swaying, thus weaken ship rocking movement, reach the self-stability auxiliary device for ship by means of water-jet propulsion of stable boats and ships object.
Technical solution of the present invention is: a kind of self-stability auxiliary device for ship by means of water-jet propulsion, it is characterized in that: it comprises the left water spray runner 1 of shape axisymmetricly and right water spray runner 2, tubaeform water inlet 3 is communicated with two water spray runner intersections, the offside of tubaeform water inlet 3 is provided with floating drum 4, the end of two water spray runners is provided with discharge port 5 and pipe link 6, and be also provided with and the left adapter shaft 7 of floating drum 4 interlock and right adapter shaft 8 in the intersection of left water spray runner 1 and right water spray runner 2, its end is respectively arranged with left valve block 9 and right valve block 10, axis along left adapter shaft 7 and right adapter shaft 8 is provided with stop block 11 at an upper portion thereof, the floating drum limiting stopper 12 be connected with floating drum 4 is also folded with between two stop blocks 11.
Compared with the existing technology, tool has the following advantages in the present invention:
The self-stability auxiliary device for ship by means of water-jet propulsion of this kind of version, its structure is simple, design ingenious, rationally distributed, it is subject to the impact of wave in the docked state for boats and ships, and the wiggly situation of certain amplitude can occur, and designs the structure that ceaselessly can produce opposite sense damping in Ship Swaying process, to reach the object weakening Ship Swaying action, for the boats and ships berthed across the sea provide one to work and the convenience operated.And its manufacture craft is simple, and cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market outlook are comparatively wide.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Fig. 6: a kind of self-stability auxiliary device for ship by means of water-jet propulsion, it comprises rigidly connected left water spray runner 1 and right water spray runner 2, and the two is arranged axisymmetricly, tubaeform water inlet 3 is communicated with in the intersection of two water spray runners, and on the water spray runner of tubaeform water inlet 3 offside, be also provided with floating drum 4, the end of these two water spray runners is provided with discharge port 5 and pipe link 6, and also cross-under has left adapter shaft 7 and right adapter shaft 8 in the junction of two water spray runners, one end of these two adapter shafts is connected with floating drum 4, the other end is respectively arranged with left valve block 9 and right valve block 10, and along the axis of left adapter shaft 7 and right adapter shaft 8, be provided with stop block 11 at an upper portion thereof, the floating drum limiting stopper 12 be connected with floating drum 4 is then folded with between two stop blocks 11.
The working process of the self-stability auxiliary device for ship by means of water-jet propulsion of the embodiment of the present invention is as follows: the afterbody first this auxiliary device being connected to boats and ships, utilize pipe link 6 this device and boats and ships to be rigidly connected, tubaeform water inlet 3 is connected with the waterjet propulsor water injector of boats and ships simultaneously.
In the wiggly process of boats and ships, because floating drum 4 only has longitudinal motion relative to the water surface, there is no rocking motion, namely floating drum is relative to boats and ships wigwag motion, again because water spray runner and boats and ships are rigidly connected, that is floating drum is relative to water spray runner, with left adapter shaft 7 and right adapter shaft 8 place for pivot point swings.
When boats and ships be in not run-off the straight ideally time, the uniform fluid flow sprayed from waterjet propulsor by left water spray runner 1 and right water spray runner 2, the stressed equalization of the right and left;
When boats and ships occur left-leaning, also be tilted to the left with the rigidly connected water spray runner of boats and ships, but because the left adapter shaft 7 that is connected with floating drum and right adapter shaft 8 do not tilt relative to the water surface, so the left valve block 9 be connected on adapter shaft and right valve block 10 are relative to the run-off the straight of water spray runner, the space that the water supply that right valve block 10 and right water spray runner 2 are formed flows through increases, the space that the water supply that left valve block 9 and left water spray runner 1 are formed flows through reduces, even closed, therefore current all enter sea by the discharge port 5 on right water spray runner 2, a direction resistance is left formed to boats and ships, weaken the trend of boats and ships "Left"-deviationist,
When boats and ships generation Right deviation, working process describes contrary with epimere, weakens the trend of boats and ships Right deviation.
Floating drum limiting stopper 12 can limit left adapter shaft 7 clickwise with the existence of the stop block 11 of its both sides, limit right adapter shaft 8 left-hand revolution, and when ship inclination angle is larger (as shown in the figure), left valve block 9, under the effect of left water spray runner 1 inwall, drives left adapter shaft 7 that left-hand revolution occurs.
