The specific embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
The utility model is the repacking that the liferaft peculiar to vessel 2 of standard is discharged control.As shown in Figure 1, fixing between the liferaft 2 of standard and the raft frame 3 with steel rope 1, the cover liferaft remote control release gear of between steel rope 1, manual releasing hook (not shown) and hydrostaticrelease unit 4 and raft frame 3 attachment points, packing into, as long as both have one to start release like this, just can the steel rope 1 that liferaft 2 and raft frame 3 are fixed be separated, realize the release of liferaft 2.
As shown in Figure 1 to Figure 3, the utility model liferaft remote control release gear is installed between the steel rope 1 and raft frame 3 attachment points of fixing liferaft 2.As shown in Figure 1, the utility model liferaft remote control release gear comprises the gas control device 5 that overlaps between steel rope 1 and raft frame 3.As shown in Figures 2 and 3, this gas control device 5 comprises: compressed-air actuated source of the gas, two-position-five-way solenoid valve 56, electromagnetic valve electric-control system 7, cylinder 51 are provided and place cylinder piston 511 in this cylinder 51 and locating dowel pin 52, adapter plate 54 and two locating pieces 53 and steel wire loop 11.Wherein, locating dowel pin 52 is bolted to connection with this cylinder piston 511, and adapter plate 54 is positioned at cylinder 51 belows and is fixed on the raft frame 3.Pressurized air feeds two-position-five-way solenoid valve 56 along tracheae 58 and arrives cylinder 51.The unlatching of electromagnetic valve 56 gas circuits, close by electric-control system 7 control.
As shown in Figure 2, an end of above-mentioned locating dowel pin 52 and cylinder piston 511 are fixing, and the other end stretches out outside the cylinder 51.One face down bonding of cylinder 51 is connected to two locating pieces 53, and this locating piece 53 is welded on the adapter plate 54, and a knock hole (not shown) is respectively bored in the top of this locating piece 53 and locating dowel pin 52 corresponding positions, two position of positioning hole correspondences.The aperture of knock hole should be slightly larger than the diameter of axle of locating dowel pin 52, makes locating dowel pin 52 movable being interspersed between this two knock hole under the drive of cylinder piston 511.
As depicted in figs. 1 and 2, fixing steel rope 1 end of liferaft 2 is made a steel wire loop 11, and be suspended between two knock holees.The bore of this steel wire loop 11 is much larger than the external diameter of locating dowel pin 52.Drive locating dowel pin 52 parallel motions by cylinder piston 511, and the parallel motion by locating dowel pin 52, make steel wire loop 11 be set on the locating dowel pin 52 and be locked between two locating pieces 53, thereby the liferaft 2 that will link to each other with steel wire loop 11 is locked on the raft frame 3.
As shown in Figure 3, the electric-control system 7 of above-mentioned electromagnetic valve 56 is composed in series by control power supply, electromagnetic valve coil 561 and four groups of control buttons parallel with one another 61～64.The two ends of electromagnetic valve coil 561 and four groups of open contacts control button 61～64 parallel with one another Access Control power supply of connecting.Under the situation as shown in Figure 2, four groups of control buttons 61～64 are positioned at normally open.
In the preferred embodiment of the present utility model, between compressed gas source and electromagnetic valve 56, be connected with a screw down nonreturn valve 55.Screw down nonreturn valve 55 is set, can prevents to interrupt, break down or when the maintenance, still can lock liferaft 2 such as compressed air system in pressurized air.So just avoided compressed gas source not because of locking the situation that discharges voluntarily.
In addition, the impulsive force that the application force during for buffer switch produces cylinder 51 two ends, four-way gas port S and five-way gas port R at two-position-five-way solenoid valve 56 have all installed exhaust shutter 57, to prolong the service life of cylinder 51.
The utility model device is connected in series with the steel rope 1 of original manual releasing hook and hydrostaticrelease unit 4, does not influence liferaft 2 original release functions.The pressurized air that source of the gas adopts common ship to use mixedly provides power.
As shown in Figures 2 and 3, control principle of the present utility model is as follows:
Each control button 61～64 that to control two-position five-way valve 56 gas circuits at ordinary times disconnects, and two-position five-way valve 56 is in initial position shown in Figure 2.Pressurized air is by screw down nonreturn valve 55, enters the first vent P of two-position-five-way solenoid valve 56 through the tracheae 58 of diameter 10mm, arrives the 3rd vent B of electromagnetic valve 56 again, enters the left part cavity of cylinder 51 through tracheae 58.Pressure acts on cylinder piston 511 bottoms, to the power of cylinder piston 511 generations greater than 300 kilograms, make it to right translation, the locating dowel pin 52 that drive is captiveed joint with cylinder piston 511 is to right translation, after entangling steel wire loop 11, pierce into knock hole, so just firmly pinned liferaft 2 with steel wire loop 11 bindings.
When the drowning emergency situation that need succour of people takes place, can press any one in four control knobs 61～64 that are arranged in different positions nearby, make the two-position-five-way solenoid valve 56 of series connection with it and control power connection.Under the effect of electromagnetic force, spool moves, and the vent P that wins is communicated with the second vent A, and the 3rd vent B is communicated with five-way gas port R simultaneously, and four-way gas port S blocking-up is not communicated with other mouthfuls; Pressurized air arrives the right part cavity that the second vent A enters cylinder 51 through the first vent P.Pressure acts on cylinder piston 511 right parts, and the air of cylinder piston 511 left parts can arrive five-way gas port R through the 3rd vent B simultaneously, and four-way gas port S blocking-up is not communicated with other mouthfuls, and discharges into the atmosphere through exhaust shutter 57.Cylinder piston 511 is moved to the left under compressed-air actuated effect, the locating dowel pin 52 that drive is installed on the cylinder piston 511 is moved to the left together, the fixing steel wire loop 11 of liferaft 2 is untied from locating dowel pin 52, and the liferaft 2 that will link to each other with steel wire loop 11 discharges rapidly.Adopt the utility model device to compare original man overboard and succour when taking place, need the ship's staff to arrive in liferaft 2 next doors and manually discharge again and will shorten many valuable time.
In like manner, as shown in Figure 2, when unclamping control button, two-position-five-way solenoid valve 56 dead electricity, spool can set back under the effect of spring force, and pressurized air enters cylinder piston 511 left side cavitys again, and locating dowel pin 52 levels are moved to right, and gets back to the position of locking.
The coupling mechanism force of gas control device 5 is calculated as follows in the utility model most preferred embodiment:
The P=0.7MPa ≈ 7Kg/cm that adopts common ship to use mixedly
2Pressurized air is as power,
Wherein, cylinder piston 511 diameters: d=7.5cm, r=d/2=3.75cm;
Latching force F=P x S=7 x 44.15=309Kg.
The latching force of this device reaches 309 kilograms, is enough to guarantee stable at ordinary times pinning liferaft 2.
Though more than described the specific embodiment of the present utility model, but those skilled in the art is to be understood that, these only are casehistorys, under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
