In the present embodiment, the 6 piston rod front end of the second oil cylinder has and can cooperate with first sleeve 5 or feeler lever
Arc surface, as shown in Figure 10.
The working principle of above-mentioned penetration sounding system is as follows:
In the initial state, 304 a part of snap-gauge in 302 side wall card slot 3021 of the second casing is in screens axle 303
In the lower endless groove 3032 for holding annular convex platform 3031, by snap-gauge 304 and leaf spring 305 to the branch of annular convex platform 3031
The annular convex platform 3031 of screens axle 303 is limited in 304 top of snap-gauge by support effect, even if so that first sleeve 5 is visited in recycling
Bar 8 under gravity and the effect of ground frictional force, the feeler lever that is connect with screens axle 303 can not relative to first sleeve 5 individually to
Lower movement, the state are as self-locking.
When carrying out the operation of ocean static sounding, first starting two group of second oil cylinder 6 forward extends out piston rod, two pistons
Bar relative extension clamps first sleeve 5, and then starting the first oil cylinder 7 shrinks piston rod, moves downward oil cylinder set with band
Dynamic first sleeve 5 moves downward, the second casing 302 synchronize move downward when, on 302 lower end surface of the second casing and the shaft shoulder 306
End face contacts and applies downward pressure to screens axle 303, forces screens axle 303 and feeler lever 8 can be same with the second casing 302
Walk downward injection.After first sleeve 5 moves downward a distance, 6 piston rod of the second oil cylinder is shunk, by 5 pine of first sleeve
It opens, then 7 piston rod of the first oil cylinder extends, and increase oil cylinder set, and then the second oil cylinder 6 continues to clamp first sleeve 5, the
The oil cylinder set of one oil cylinder 7 moves downward, and promotes the further downward injection of first sleeve 5.Repeatedly, when 5 upper end of first sleeve
After dropping to the second oil cylinder 6 and can not being clamped, the second oil cylinder 6 can also directly be clamped feeler lever, and by the first oil cylinder 7 into
One step makes feeler lever further downward injection, to keep the depth of feeler lever injection deeper.
When directly clamping feeler lever makes feeler lever individually downward injection to the second oil cylinder 6, need to overcome self-locking mechanism to feeler lever
It is self-locking.Downward penetrating power is applied to feeler lever by the first oil cylinder 7 and the second oil cylinder 6, while starting third oil cylinder 12 for
Sleeve 5 clamps, and feeler lever is during external force downward injection, due under 303 upper end annular convex platform 3031 of screens axle
End face and 304 top edge of snap-gauge are inclined surface, thus the annular convex platform 3031 of screens axle 303 can apply to snap-gauge 304 to
Outer thrust, snap-gauge 304 can promote 305 both ends of leaf spring to open to two sides under the action of the thrust, bend high reduction, to make card
Plate 304 is gradually mobile to 305 side of leaf spring, after the excircle of annular convex platform 3031 is crossed in 304 lower surface of snap-gauge, that is, releases card
Plate 304 can continue to move downward to the locking effect of annular convex platform 3031, feeler lever under the action of penetrating power, carry out further
Injection operation.
In above-mentioned penetration process, using 4 formula injection system of platform, the tide is flowing and ebbing can be effectively prevent to feeler lever injection
It influences, guarantees the stability of feeler lever penetration process；Feeler lever is protected in penetration process using first sleeve 5, Neng Gouyou
Effect prevents feeler lever from the problem of bending or fractureing occurring in penetration process.
When recycling to first sleeve 5 and feeler lever, self-locking mechanism is needed to lock feeler lever.Third is kept first
Then feeler lever is clamped the clamped condition of first sleeve 5 by oil cylinder 12 by the second oil cylinder 6, the first oil cylinder 7 of starting makes oil cylinder set
Rise, drive feeler lever to be lifted up by the second oil cylinder 6, since first sleeve 5 is clamped, feeler lever is in the mistake being lifted up
Cheng Zhong, 3031 upper surface of annular convex platform in screens axle 303 can gradually open the snap-gauge 304 of two sides, until between two snap-gauges 304
Spacing be more than or equal to 3031 outer diameter of annular convex platform, then annular convex platform 3031 can cross snap-gauge 304 and continue up, until ring
Shape boss 3031 is completely by the way that after snap-gauge 304, snap-gauge 304 can enter in 3031 lower grooves of annular convex platform.By on snap-gauge 304
Edge guarantees feeler lever integral locking to first sleeve 5 with the engaging of 303 upper end annular convex platform of screens axle, 3031 lower end surface
During being lifted up, feeler lever can be synchronized with first sleeve 5 and be moved upwards, without falling downwards.
It should be noted that the application essentially consists in the overall structure of 4 formula ocean static sounding device of protecting platform, and on
It states system and also needs to configure corresponding detection device and electrical control equipment in implementation process, probe needs to pass through connection
It connects data collecting instrument 10 (such as PeneLoger-lll PS011205 model), data collecting instrument is passed for obtaining probe in real time
The Various types of data of sensor detection, and operation, display and storage are carried out, the data transmission that then will acquire to server 11.It is above-mentioned
Process also needs to use depth gauge or displacement measuring instrument, detects to the depth of penetration to feeler lever, depth can be used
Encoder, the depth gauge are mounted on the first oil cylinder 7, are connect by data line with data collecting instrument, to obtain passing through for probe
Enter depth, and the penetrating speed of probe can be obtained indirectly.
Embodiment two
On the basis of the above embodiment 1, the installation site of the second oil cylinder 6 can also be further improved.Its side
Case are as follows:
Injection driving mechanism includes two groups of first oil cylinders 7 being longitudinally set on platform 4, the piston rod of the first oil cylinder 7 and flat
Platform 4 is fixed, is fixedly connected between two group of first oil cylinder 7 and clamps bracket 13, clamps central be equipped with of bracket 13 and is used for first sleeve 5
The through-hole passed through with feeler lever, the first clamp system include two group of second oil cylinder 6, and the cylinder sleeve of two group of second oil cylinder 6 is fixed on described
It clamps on bracket 13, two piston rods are just oppositely arranged, and two piston rod central axis and feeler lever central axis are in same flat
