As shown in Figure 1, Figure 3, unlocking type retaining mechanism is triggered to be used to connect vertical mounting cylinder and base.The present embodiment touches It is two to send out unlocking type retaining mechanism, and two triggering unlocking type retaining mechanisms are distributed in the opposite sides of base.
Triggering unlocking type retaining mechanism includes being arranged on the spacing hole 3.6 on chassis outer side face, the water coaxial with spacing hole Flat cylinder body 3.1, the connector of the horizontal cylinder body of connection and vertical mounting cylinder, the first annular limit that is arranged in horizontal cylinder body on side Position block 3.3, be slidably arranged in horizontal cylinder body latching ram 3.2, be connected with latching ram piston rod 3.4, be arranged on Connect the first interface 3.5 on horizontal cylinder outside, the subsidiary cylinder 3.8 coaxial with horizontal cylinder body and be slidably arranged in subsidiary cylinder Interior auxiliary piston 3.7.The internal diameter of horizontal cylinder body is more than the internal diameter of auxiliary piston.One end of subsidiary cylinder is connected with the inner chamber of horizontal cylinder body It is logical, another end opening of subsidiary cylinder.Auxiliary piston is provided with the pull bar 3.9 coaxial with subsidiary cylinder, and the end of pull bar is located at subsidiary cylinder Outside.
Piston rod is located at the same side of latching ram with spacing hole.Piston rod is coaxial with spacing hole.Piston rod and subsidiary cylinder Positioned at the opposite sides of latching ram.Pull bar is located at the opposite sides of auxiliary piston with latching ram.First interface, first annular limit Position block and piston rod are located at the same side of latching ram.First interface is located at relative the two of latching ram with first annular limited block Side.The end of piston rod is through horizontal cylinder body and positioned at the outside of horizontal cylinder body.When latching ram is against first annular limited block When upper：The end of piston rod is stretched into spacing hole.
As Figure 1 and Figure 4, floating trigger mechanism is used to control the retaining mechanism unblock of triggering unlocking type.
Floating trigger mechanism includes triggering connecting rope 4.3, is arranged on the medial surface of vertical mounting cylinder and is put down positioned at installation The second ring limit block 4.2 above plate, it is arranged in vertical mounting cylinder and positioned at floating plate below the second ring limit block 4.1st, the vertical cylinder body 4.4 above floating plate, the vertical cylinder body of connection and vertical mounting cylinder connector, be slidably arranged in Upper piston 4.10 in vertical cylinder body with lower piston 4.8, be connected the piston rod of upper piston and lower piston, be arranged on vertical cylinder body Lower piston limited block 4.6 on medial surface and below the lower piston, it is arranged in vertical cylinder body and below lower piston Reseting pressuring spring 4.5 and the second interface 4.9 being arranged on vertical cylinder body lateral surface.
Floating plate is positioned at the top of installation flat board.The buoyancy of floating plate is more than gravity, in the present embodiment, floating plate Buoyancy be slightly larger than gravity, the buoyancy of floating plate and the difference of floating plate gravity are 0.5-3 kilograms.
The upper end of vertical cylinder body is provided with upper through hole 4.11.The lower end of vertical cylinder body is provided with lower through-hole 4.7.Contact fuze rope Upper end is connected with lower piston, and the lower end of contact fuze rope is connected through upper through hole and with floating plate.First interface passes through Connecting tube is connected with second interface.
When upper piston is against on the upper surface of vertical cylinder body：Second interface is between upper piston and lower piston；Instantly When piston is against on lower piston limited block：Second interface is located at the top of upper piston.
The device for improving seining cultivation base bottom environment of the present embodiment it is specifically used as follows：
First, EM bacterium solutions are filled in the storage filling of EM bacterium by entering fluid through-hole, then sealed by entering fluid through-hole seal plug Enter fluid through-hole, so as to which EM bacterium solutions are stored in the storage filling of EM bacterium；
Then, vertical mounting cylinder is placed on the upper surface of base, meanwhile, the upper end for filling the storage of EM bacterium is stretched into corresponding spacing In set, buckle is stuck in the annular slot that corresponding EM bacterium storage fills, fixed so as to which EM bacterium are stored into filling installation by buckle In vertical mounting cylinder.
Followed by connecting tube is separated with first interface, then, auxiliary piston is pushed away inside by pull bar, is lived from locking is made Plug drives piston rod to stretch out, until latching ram is against on first annular limited block, now, corresponding to the end of piston rod is stretched into In spacing hole, so as to which vertical mounting cylinder is connected on base；Followed by connecting tube is connected with first interface.
Second, the device for improving seining cultivation base bottom environment is transferred into seabed in advance, for example, in certain batch of horizontal product （Large yellow croaker）Transferred in advance before cultivation or by the device for improving seining cultivation base bottom environment before a certain cultivation stages To seabed.After the device decentralization for improving seining cultivation base bottom environment is marine, floating plate in buoyancy float downward simultaneously It is against in the second ring limit block, as shown in Figure 1.After the device for improving seining cultivation base bottom environment transfers to seabed, The device for improving seining cultivation base bottom environment is supported in seabed by base.
In the breeding process of plant afterwards, a part of residual bait, fish excreta and other deposits will be gradual Deposit on floating plate, when the deposit on floating plate reaches constant weight, floating plate will slowly sink；Floating In flat board sinking watching, upper piston and lower piston is driven together to move down the effect for overcoming reseting pressuring spring, until lower piston is against Untill on lower piston limited block, now, second interface is located at the top of upper piston, so that the inner chamber of horizontal cylinder body passes through second Interface, connecting tube and first interface connect with extraneous seawater.When the inner chamber of horizontal cylinder body passes through second interface, connecting tube and first After interface connects with extraneous seawater, because the internal diameter of horizontal cylinder body is more than the internal diameter of auxiliary piston, in the presence of hydraulic pressure, locking is lived Plug will drive piston rod toward moving in horizontal cylinder body, so that piston rod separates with spacing hole.When piston rod separates with spacing hole Afterwards, vertical mounting cylinder is by the buoyancy float downward of buoyant mass.
In vertical mounting cylinder floating-upward process, the storage of EM bacterium will be driven to fill by buckle and together floated, filled when EM bacterium store After closure post separation, the EM bacterium solutions in the storage filling of EM bacterium store the lower ending opening filled by EM bacterium and are discharged into environments such as subsea, So as to improve cultivation field marine bottom environment eutrophication using EM bacterium, reduce aquaculture to shadow caused by bottom soil environment Ring.
On the other hand, so can be with due to the device for improving seining cultivation base bottom environment is transferred into seabed in advance In deposits such as residual bait, fish excretas in sea-bottom deposit to certain level when, automatic triggering improves seining cultivation base substrate The device of environment, EM bacterium solutions are discharged into environments such as subsea, so as to improve cultivation field marine bottom environment eutrophy using EM bacterium Change, reduce aquaculture to influence caused by bottom soil environment, it is not only easy to operate when to launch EM bacterium without artificial judgment, And handle timely.
After vertical mounting cylinder floats to sea, vertical mounting cylinder is connected by the first connecting rope with base, so can be with Vertical mounting cylinder is avoided to be walked with wave floating, at the same time it can also reclaim base by the first connecting rope.
