The contact surface of the head of the lock tongue 3 and the transition block 7 is a circular arc surface.
The mounting structure of the weight box 1 is as follows: the rear part of the frame 2 is provided with supporting bosses 9 at intervals, the supporting bosses 9 support the rear end of the weight box 1, the frame 2 at the two sides of the weight box 1 is also provided with guide wheel assemblies 300, and the front end of the weight box 1 is connected with the release mechanism 100.
The specific structure and function of the invention are as follows:
mainly comprises a driving assembly 200, a releasing mechanism 100, a weight box 1 and a guide wheel assembly 300,
the release mechanism 100, weight box 1 and guide wheel assembly 300 are mounted to the bottom of the submersible 400.
The structure of the release mechanism 100 is: including spring bolt 3 and release lever 4, spring bolt 3 is connected with frame 2 through round pin axle 5, and between two support otic placodes 6 of release lever 4 installation in frame 2, transition piece 7 is equipped with to 4 front ends of release lever, and transition piece 7 is pushed down to spring bolt 3, and the anticlockwise upset of restriction release lever 4 is in order to play the pinning function. Two releasing blocks 8 are arranged at the rear end of the releasing rod 4 and support the front end of the lifting block box 1 together, two supporting bosses 9 are welded at the rear part of the frame 2 and support the rear end of the weight box 1 together, and the releasing blocks 8 and the supporting bosses 9 limit the longitudinal displacement of the weight box 1 along the fore-aft direction of the submersible vehicle at the same time.
The structure of the driving assembly 200 is: comprising a drive cylinder 10, a manual pump 11 and hydraulic piping 12. The manual pump 11 is installed in a cab in the front of a manned cabin of the submersible vehicle, and is connected to an oil inlet of a driving oil cylinder 10 on an extravehicular frame 2 through a hydraulic pipe system 12, hydraulic oil enters a rod cavity of the driving oil cylinder 10 through the oil inlet, a cylinder barrel end of the driving oil cylinder 10 is hinged with an oil cylinder lug plate 13, a rodless cavity inside a cylinder barrel of the driving oil cylinder 10 is provided with a compression spring 14, one end of the compression spring 14 abuts against the barrel bottom, the other end of the compression spring abuts against the bottom of a piston rod of the driving oil cylinder 10, the head of the piston rod is hinged with a lock tongue 3 of a release mechanism 100, and the compression spring 14 prevents the lock tongue 3 from being overturned.
In addition, the contact surface of spring bolt 3 and transition piece 7 is the arc surface, and the circular arc center is the rotation center of spring bolt 3, and under the non-throwing load state, release lever 4 points to this rotation center to the effort of spring bolt 3, and spring bolt 3 can not receive the unexpected upset unblock of the change of effort all the time.
An oil outlet of the driving oil cylinder 10 is provided with a one-way valve 15, under the non-load rejection state, outside water cannot enter the rodless cavity, and the compression spring 14 is always in an oil environment, so that corrosion and failure are avoided; under the load rejection state, the hydraulic oil in the rodless cavity is extruded to flow out of the oil outlet.
In the practical use process, when the weight box 1 needs to be abandoned, the stop valve of the hydraulic pipe system 12 is firstly opened, then the manual pump 11 is driven, so that hydraulic pressure is transmitted to the driving oil cylinder 10 to form a rod cavity, the piston rod is contracted to pull the bolt 3 of the release mechanism 100, the release rod 4 is unlocked and rotated to release the weight box 1, and the weight box 1 is overturned downwards by taking the contact point of the supporting boss 9 as a rotation center, so that load rejection is realized. Before the weight box 1 is not discarded, the compression spring 14 compresses the piston rod, so that the bolt 3 safely presses the release block 8, and the release block 8 and the support boss 9 safely support the weight box 1.
The weight housing 1 is turned over and discarded such that the release lever 4 only has to bear half the weight of the weight housing 1. Because the installation space of the load rejection device is extremely limited in height, the release lever 4 can only be designed into a non-labor-saving lever, and the force arms on the two sides are basically the same. However, the resistance mainly overcome by the unlocking of the driving oil cylinder 10 is the friction force between the bolt 3 and the transition block 7, since the static friction coefficient of metal is only about 0.15, the friction force is small, the driving force of the oil cylinder is large, the driving oil cylinder 10 can pull the bolt 3, the bolt 3 is separated from the transition block 7, the release lever 4 and the release block 8 rotate, the front end of the weight box 1 is released, so that the weight box 1 turns downwards around the support boss 9 in a pointing manner, and is finally unloaded, therefore, the heavy weight box 1 can be discarded by the load rejection device.
The invention installs guide wheel components 300 on the frame 2 at both sides of the weight box 1, including the pressure plate 16 and the pulley 17, and there are two sets of guide wheel components 300 at each side. The pressing plate 16 restrains the shaking of the weight box 1 in the vertical direction, and the pulley 17 limits the lateral displacement of the weight box 1 and plays a role in guiding when the load is thrown.
In the present invention, the driving assembly 200 is designed redundantly, that is, the driving assembly 200 is provided with two sets of driving cylinders 10 and two sets of manual pumps 11 connected with the hydraulic piping 12.
The hydraulic piping system 12 is divided into two paths, each path is composed of a manual pump 11, a pressure gauge (not shown in the figure), a stop valve (not shown in the figure), a cabin penetrating piece (not shown in the figure), a driving oil cylinder 10, a one-way valve 15 and a pipeline, and the on-off between the two paths is realized by controlling the stop valves.
When load rejection operation is executed, the stop valve is opened, the two driving oil cylinders 10 work, and the lock tongue 3 is pulled to act under the action of the piston rods of the driving oil cylinders 10, so that the load rejection operation is realized.
When certain equipment of wherein pipeline damages all the way, close the contact that the stop valve cut off two ways, use manual pump 11 to transmit hydraulic pressure force, judge which is unusual pipeline through the numerical value of observing the manometer, the pipeline that becomes invalid promptly uses the normal pipeline of manometer numerical value to realize throwing and carrying. It is flexible and convenient to use.
The above description is intended to be illustrative and not restrictive, and the scope of the invention is defined by the appended claims, which may be modified in any manner within the scope of the invention.
