The utility model has the advantages that the employing electrical control, can realize that the chaufeur front portion controls the effect of ship, can be with powered version at the arbitrarily angled outboard engine body of raising at any time; Regulate the best propelling of going of propelling screws angle, and make outboard engine have the Anti-bumping protection function, and simple in structure; Governing speed is fast, and volume is little, and cost is low; Use face width, safe and convenient to use.
Description of drawings
Figure is the utility model structural representation.
The specific embodiment
As shown in the figure, a kind of electric liquid device that warps mainly is made up of piston cylinder 3, bypass control 8, DC machine 20, lead 17, piston 7, piston rod 2 and 6 of piston rings.Piston cylinder is positioned at body 16 1 sides.The body upper end is provided with DC machine, is provided with the gear type pump 18 that is driven by DC machine in the body of DC machine lower end, and DC machine is through motor shaft 19 driven gear pumps.It is piston cylinder epicoele 4 and piston cylinder cavity of resorption 10 that the piston that is positioned at piston cylinder is cut apart piston cylinder.The piston cylinder sidewall is connected with last through tube 5 sidewalls.Last through tube one end is communicated with the piston cylinder epicoele in the piston cylinder outside, and the other end of last through tube is communicated with counter-rotating pump oil through change-over valve 15 and goes out pipe 9.Piston cylinder cavity of resorption through tube 13 1 ends that communicate down, the other end of following through tube are communicated with through change-over valve just to be changeed pump oil and is going out pipe 14.Piston is provided with the upper and lower chamber of control plunger cylinder and connects or osed top bypass control 8.Piston cylinder bottom is provided with floating piston 22, is provided with spring 23 between floating piston lower end and the piston cylinder bottom, when floating piston is used to prevent the piston rod fast retractile to the impact bottom the piston cylinder.
Described piston upper end connects the piston rod draw ring 1 that is positioned at outside the piston cylinder top cover 21 through piston rod.The body of described piston cylinder lower end is provided with coupling link 11.
Piston ring and seal ring are positioned on the piston side wall, and the packed-piston upper and lower end forms the upper and lower chamber of leak free piston cylinder.The piston upper center connects piston-rod lower end.Be connected again after the piston rod middle part is coupling through seal ring and sealing cap and piston cylinder top cover mider hole sealing and be positioned at piston cylinder top cover 21 piston rod draw ring outward.The piston cylinder top cover is spirally connected through seal ring and piston cylinder end sealing.
During use, oneself injects an amount of high-voltage oil liquid in advance in piston cylinder and gear type pump through body sealing nut 12.Positive and negative direction rotation can be done through master cock in DC machine energising back, as the drive power source geared oil pump, to high-voltage oil liquid pressure energy is provided.Under normal condition, piston is in contraction state.With versatile spindle outboard engine is put in the ship rear end; The coupling link and the outboard engine middle part of the utility model is fixing; Will be fixing with piston rod draw ring and cooresponding ship side group that piston rod fuses; The cable both positive and negative polarity of DC machine is connected with storage battery through control circuit, through the master cock control DC machine of control circuit.
When the operator needed going of upper and lower adjustment propelling screws to advance the angle, master cock was beaten to forward one side, and DC machine is rotated in the forward; Driving gear through motor shaft and coupler driven gear pump is rotated in the forward; The high-voltage oil liquid of gear pump driven is just changeing pump oil and is going out pipe and get into change-over valve, drives change-over valve core and moves to left, and will just change pump oil and go out pipe and be communicated with following through tube; High-voltage oil liquid edge through tube down gets into the piston cylinder cavity of resorption; Move and drive piston rod on the driven plunger and move on also, piston rod drives the outboard engine prop shaft certain angle of facing upward simultaneously, relies on screw propeller to advance the vertical direction component of counter-force to reach the go purpose of angle of downward modulation bow; Otherwise master cock is beaten to a reverse side, DC machine backward rotation; Driving gear contrarotation through motor shaft driven gear pump; Just changeing the high-voltage oil liquid pressure that pump oil goes out in the pipe and be lower than the high-voltage oil liquid pressure that counter-rotating pump oil goes out pipe, the spool of high-voltage oil liquid reverse drive change-over valve moves to right, and will go up through tube and go out to manage with counter-rotating pump oil and be communicated with; High-voltage oil liquid gets into the piston cylinder epicoele by last through tube; Drive piston cylinder moves down and drives piston rod and also moves down, and simultaneously piston rod drives outboard engine prop shaft nutation certain angle, relies on screw propeller to advance the vertical direction component of counter-force to reach to raise the go purpose of angle of bow.
If under piston rod is in the state of ejecting; Prominent and the thing collision under water of outboard engine when reaching certain impact, is roughly equal to 1～1.5 ton of lower apron that is not enough to damage outboard engine this moment; Impact drive this moment piston rod pulling piston is opened the bypass control (force value is 1～1.5 ton) on it; The piston cylinder upper and lower end is connected, impact is driven on the outboard engine lift, thing collides thereby escape under water; Quick impact energy during the withdrawal of the unsteady damper piston absorption piston rod of piston cylinder bottom simultaneously reaches the buffering purpose.Then outboard engine weight is oppressed piston reset again.
In a word, the utility model adopts electrical control, can realize that the chaufeur front portion controls the effect of ship; Can regulate the best propelling of going of propelling screws angle, and make outboard engine have the Anti-bumping protection function at the arbitrarily angled outboard engine body of raising at any time with powered version; And simple in structure, governing speed is fast, and volume is little; Cost is low, uses face width, and is safe and convenient to use.
