The lower plugging member 500 is in the form of a sliding piston, and is connected to the inner wall of the sliding chamber 320 in a sealing manner by a sealing ring.
After whole anchor 400 drops into under water, rivers can get into through the second water filling port, then exert water pressure and give the lower shutoff piece 500 that is located sliding chamber 320, after anchor 400 sinks to certain degree of depth, water pressure can promote down the inside removal of shutoff piece 500 to storehouse body 120 down, finally make in shutoff piece 500 is pushed storehouse body 120 down, the second water filling port, sliding chamber 320 and storehouse body 120 intercommunication down, the rivers flow in through second water injection portion 321 flows into storehouse body 120 down. After the water flow enters the lower chamber body 120, the positive buoyancy is changed into the negative buoyancy, and the sinking movement is started, at the moment, the fluke piece 410 is also separated from the second chamber body 314 and embedded into the sea mud, so that the stable operation of underwater equipment is ensured.
In some embodiments of the present application, the cross-sectional area of the lower block piece 500 is set to be larger than the cross-sectional area of the upper block piece 112.
Because the cross-sectional areas of the lower plugging piece 500 and the upper plugging piece 112 are different, an area difference exists, so that a pressure difference can be formed between the lower plugging piece 500 and the upper plugging piece 112 when water pressure is received in water, and when the difference exceeds the sum of the sealing friction force corresponding to the upper plugging piece 112 and the lower plugging piece 500, the lower plugging piece 500 can slide relative to the sliding cavity 320, is separated from the sliding cavity 320, is not sealed to the sliding cavity 320 any more, and water flow is injected into the lower bin body 120.
The lower plugging piece 500 and the upper plugging piece 112 are both connected to the connecting piece 200, and when the lower plugging piece 500 moves towards the lower bin body 120, the connecting piece 200 and the upper plugging piece 112 are both driven to slide.
In some embodiments of the present application, the anchor piece 410 is provided with a protruding block 411 on the side contacting with the side wall of the second cavity 314. Specifically, raised bumps 411 are arranged on both sides of fluke piece 410, so that the contact area between fluke piece 410 and accommodating cavity 310 can be reduced, the friction force between fluke piece 410 and accommodating cavity 310 is reduced, and the extending efficiency of fluke piece 410 is improved.
When the built-in pressure control anchor is arranged, the sliding part 430, the fluke piece 410, the anchor rod 420 and other parts of the anchor device 400 are completely hidden in the lower end cover 300 of the bin body 100, so that the whole anchor device 400 has the advantages of compact structure, small occupied space, convenience in transportation and simple structure;
when the anchor device 400 needs to be thrown, the anchor device 400 only needs to be placed in water, after the anchor device reaches a certain depth of water, the lower plugging piece 500 can automatically drive the connecting piece 200 and the upper plugging piece 112 to slide relative to the sliding cavity 320 under the action of water pressure, and the lower plugging piece 500 enters the lower cabin body 120 so as to inject water into the lower cabin body 120 and automatically sink the anchor device 400 for placement;
meanwhile, when the fluke is opened, only the water depth needs to reach a certain depth, the water pressure can apply force to the sliding part 430 to push the sliding part to slide along the accommodating cavity 310, the anchor rod 420 and the fluke piece 410 connected with the anchor rod 420 are pushed to move, the fluke piece 410 is enabled to be separated from the first outlet part 312 outwards, automatic release of the fluke piece 410 is achieved through the water pressure, extra power is not needed, manual participation control is not needed, and throwing and laying work is facilitated.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
