In this embodiment, the first control valve 212, the second control valve 213, the third control valve 222, and the fourth control valve 223 are preferably butterfly valves. A butterfly valve, also called a flap valve, is a regulating valve with simple structure, and can be used for the on-off control of low-pressure pipeline media, namely a valve which is opened and closed by rotating around a valve shaft, wherein a closing member (a valve clack or a butterfly plate) is a disk. The pipe mainly plays a role in cutting off and throttling. The butterfly valve opening and closing piece is a disc-shaped butterfly plate and rotates around the axis of the butterfly plate in the valve body, so that the opening and closing or adjusting purpose is achieved.
In this embodiment, the mounting frame 10 primarily serves to protect its internal mounting components and to connect to the bucket structure 60. The hydraulic pump group 20 mainly functions as follows: during sinking, water is pumped from the interior of the bucket structure 60 to form negative pressure difference; during the floating process, water is injected into the barrel structure 60 to form a positive pressure difference. A plurality of control valves are installed in the different pipelines, and under the action of the hydraulic and control unit 30, different construction states of self-weight sinking, negative pressure sinking, water injection floating and the like of the bucket structure 60 can be realized through different states of opening and closing of the control valves.
As shown in fig. 8 to 10, the automatic detaching mechanism 50 includes: the hydraulic oil cylinder 51, the rotating arm 52, the holding claw 53 and the frame 54, wherein the cylinder end and the piston end of the hydraulic oil cylinder 51 are respectively rotatably connected with the rotating arm 52, the rotating arm 52 is rotatably connected to the frame 54, the frame 54 is fixedly connected with the third pipeline 40, and the holding claw 53 is rotatably connected to the rotating arm 52, wherein under the driving action of the hydraulic oil cylinder 51, the holding claw 53 is fixedly or separately arranged with the mounting positions of the third pipeline 40 and the fourth pipeline 61; the hydraulic oil cylinder 51 is connected with the hydraulic and control unit 30 through a cable. The automatic detaching mechanism 50 has a function of automatically and rapidly detaching the fourth pipeline 61 between the present embodiment and the barrel structure 60, wherein the present embodiment uses a hydraulic system as its power source.
The number of the holding claws 53 and the number of the rotating arms 52 are two.
Further, the installation position includes a first flange 401 disposed on the third pipeline 40 and a second flange 611 disposed on the fourth pipeline 61, wherein the outer diameters of the first flange 401 and the second flange 611 are the same, and the installation position is formed when the first flange 401 and the second flange 611 are disposed in contact.
In this embodiment, as shown in fig. 9, an arc-shaped groove structure 531 is provided on the holding claw 53, and the groove structure 531 is arranged in match with the mounting position.
The rotating arm 52 is driven by the hydraulic oil cylinder 51 to enable the holding claw 53 to clamp the flanges (the first flange 401 and the second flange 611) at the joint of the third pipeline 40 and the third pipeline 40, so that the connecting function is achieved. When the construction system of the embodiment needs to be lifted off after the construction is finished, the connection at the position needs to be disconnected. Under the action of the hydraulic and control unit 30, the hydraulic cylinder 51 is retracted to drive the rotating arm 52 to release the holding claw 53, so that the construction system of the embodiment can be separated from the bucket structure 60.
The rotating arm 52 is further provided with a limiting block 521. The limiting block 521 can effectively prevent the hydraulic cylinder 51 from being released from the holding claw 53 in a single side in the retraction process, so as to prevent the hydraulic cylinder from being completely released.
The present embodiment further includes a monitoring unit, and the monitoring unit is respectively connected to the hydraulic pump unit 20 and the hydraulic and control unit 30 through cables.
The bottom of installation frame 10 still is equipped with fixed establishment 11, through fixed establishment 11 realizes the detachable connection of installation frame 10 and bucket formula structure 60. In addition to the automatic detaching mechanism 50 described above, the fixing mechanism 11 may further enhance the coupling of the construction system of the present embodiment to the tub structure 60. After the construction is completed, the automatic detaching mechanism 50 is opened to separate the fourth pipeline 61 between the construction system of this embodiment and the bucket structure 60, and the fixing mechanism 11 is disconnected at the same time, and finally the construction system of this embodiment is lifted away from the bucket structure 60.
The working principle of the embodiment is as follows:
the working state of the embodiment mainly includes 3 working conditions: self-weight sinking, negative pressure sinking and positive pressure floating. Before the working condition of automatic sinking, the fixing between the present embodiment and the barrel-type structure 60 is completed, one is to realize the connection between the present embodiment and the fourth pipeline 61 through the automatic detaching mechanism 50, and the other is to further realize the connection between the present embodiment and the barrel-type structure 60 through the fixing mechanism 11.
When the dead weight sinks under the working condition: the first control valve 212 and the second control valve 213 are opened, the third control valve 222 and the fourth control valve 223 are closed, and the third control valve 222 and the fourth control valve 223 are in a closed state and do not work. The bucket structure 60 sinks under the gravity, and seawater (sludge and other substances) in the bucket is discharged from the water outlet through the pipeline. When the dead weight sinks to a certain depth, the sinking is stopped, and the working condition of negative pressure sinking is changed: the fourth control valve 223 is opened, the second control valve 213 is closed, and the valve block is opened to operate. At this time, the inside of the tub structure 60 is sucked by the hydraulic pump unit 20, so that a negative pressure is formed in the tub, and the tub structure 60 continues to sink until the elevation depth is reached. When the barrel structure 60 needs to float upwards, the working condition is positive pressure floating: the first control valve 212 is opened, the second control valve 213 is opened, and the third control valve 222 and the fourth control valve 223 are closed, and at this time, the external seawater is pumped into the interior of the tub structure 60 through the hydraulic pump unit 20, so that a positive pressure is formed in the tub, and the tub structure 60 is floated. Then, under the action of the hydraulic and control unit 30, the automatic detaching mechanism 50 is opened to separate the fourth pipeline 61 between the construction system of the embodiment and the bucket structure 60, and the fixing mechanism 11 is disconnected at the same time, and finally, the construction system of the embodiment is lifted away from the bucket structure 60.
The installation frame is connected and fixed with the barrel type structure through the fixing mechanism, the barrel type structure sinks to a certain height through self weight, corresponding passages are formed in the pipeline through the difference of opening and closing states of the valve group in the pipeline, and the hydraulic pump set is opened, so that two construction processes of sinking or floating of the barrel type structure can be realized; the automatic detaching mechanism is opened, so that a fourth pipeline between the whole construction system and the barrel type structure is separated, and the bottom fixing mechanism is disconnected at the same time, so that the complete separation of the application and the barrel type structure is finally realized; the system has high automation degree, and underwater operation does not need diver intervention; the structure is relatively simple, and the reliability is high; the system has the advantages of low processing difficulty, easiness in construction, transportation and installation, low price and high economical efficiency.
