Description

An underwater wreck hole pumping unit base with plugging function

technical field

The invention belongs to the field of oil storage disposal of accident ships, and particularly relates to a base for drilling oil pumping equipment for underwater sunken ships.

Background technique

When the ship is in danger of sinking or other oil spill accidents, it is necessary to drill holes on the surface of the accident ship and pump the cargo oil or fuel oil in it and transfer it to a safe ship to reduce the damage of the oil spill accident. .

When the drilling oil pumping equipment is used in the deep water environment that cannot be reached by divers, it is necessary to realize the underwater unmanned operation of the drilling drilling equipment, especially the connection and separation between the equipment and the hull. After the oil pumping equipment completes the operation, the remaining operation holes need to be blocked to prevent the residual oil from overflowing and causing new pollution.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a submerged wreck perforated pumping unit base with plugging function that is convenient to realize the connection and separation between the underwater perforated oil pumping unit and the hull through remote control and can prevent residual oil from overflowing after the operation. .

In order to achieve the above object, the present invention is achieved through the following technical solutions:

An underwater wreck perforated pumping unit base with plugging function is mainly composed of a support structure 1, a transition flange 2, a controllable magnetic attraction 3, a plugging valve 4, a sealing disc 5, a low-speed motor 6, and a nail-tightening device. It consists of a fixing device 7, a fragment-free explosion bolt 8, and an anchoring lug plate 9. Among them, the upper part of the blocking valve 4 is bolted with the transition flange 2, and the lower part is bolted with the sealing disc 5; the low-speed motor 6 is installed on the support structure 1 through bolts, and the lower part is connected with the driving part of the blocking valve 4; A group of anchoring lugs 9 are evenly distributed on the outer circumference of the bottom, and each anchoring lug 9 is provided with a positioning blind hole, and the center position of the hole corresponds to the position of the nail fastener 7; the nail fastener 7 is fixed and installed by bolts On the outer circumference of the support structure 1, the lower part is inserted into the positioning blind hole of the anchoring lug plate 9, and there is no axial constraint with the anchoring lug plate 9; the upper part of the controllable magnetic attraction 3 is installed on the outer circumference of the supporting structure 1 through bolts, and the lower part is sealed with the seal The bottom of plate 5 is flush.

The support structure 1 and the transition flange 2 are connected by a set of non-fragment explosion bolts 8. After the drilling operation is completed, the non-fragment explosion bolts 8 are remotely controlled to detonate to realize the separation of the support structure 1 and the transition flange 2.

The driving part of the blocking valve 4 is connected with the lower part of the low-speed motor 6, and there is no axial restraint, only the circumferential rotation torque is transmitted. The blocking valve 4 is driven by the low-speed motor 6 to complete the opening and closing. can achieve separation.

Beneficial effects:

The connection and separation between the base and the hull and the blocking of the operation port of the present invention are all completed by remote control on the water, without the operation of an underwater diver, and it is convenient to realize underwater unmanned operation.

Detailed ways

1 to 3, the working principle and motion process of the present invention are as follows:

Before the perforated pumping unit enters the water, the present invention is installed on the bottom of the perforated pumping unit through bolts, and the low-speed motor 6 is controlled to open the blocking valve 4 to make it in an open state.

After the perforated pumping unit and the base reach the designated opening position, the switch of the controllable magnetic attraction 3 is remotely controlled from the water to make it enter the magnetized state, and the base is adsorbed on the hull to provide the perforated pumping unit perpendicular to the hull. surface adsorption.

Remotely control the firing nail fastener 7, so that the firing nails penetrate the anchoring lugs 9 and shoot into the surface of the hull, and the base and the drilling pumping unit are fixedly connected to the surface of the working hull.

After the drilling operation of the pumping unit is completed, the low-speed motor 6 is remotely controlled to work to close the blocking valve 4 .

The remote control detonation of the non-fragmentation explosive bolts 8 disables the connection between the support structure 1 and the transition flange 2 .

The switch of the controllable magnetic attraction 3 is remotely controlled to make it enter the non-magnetic state from the magnetized state, and the adsorption force between the support structure 1 and the hull disappears.

Support structure 1, nail fastener 7, controllable magnetic attraction 3, low-speed motor 6 are removed and recovered together with the drilling pumping unit; the closing valve 4 and sealing disc 5, transition flange 2, anchorage The lug plate 9 is permanently connected to the hull, and the working holes left after the operation of the drilling pumping unit are blocked to prevent the residual oil from overflowing.
