AI Technical Summary
In a ship's stranded or sunken accident, the fuel in the cabin will overflow during the oil pumping operation due to the solidification state, and it is difficult to maintain the pressure balance inside and outside the cabin during underwater pumping, which increases the risk of oil spill accidents.
A water inlet device for underwater oil pumping is designed, including connecting pipes, check valves and sludge protection covers. Through the combination of check valves and sludge protection covers, water inlets in the cabin can be realized to balance the pressure difference and prevent oil from spilling out. and silt and sand enter.
Effectively prevent oil from spilling in the cabin, maintain balance between pressure difference inside and outside the cabin, ensure safe oil pumping operation, and prevent mud and sand from entering the cabin.

Description
Technical Field
[0001] The utility model relates to the technical field of underwater salvage, and in particular to a water intake device for underwater oil pumping. Background Art
[0002] In recent years, with the rapid development of the global shipping industry, maritime transportation has become increasingly busy, the number and density of maritime activities have continued to increase, and the navigation environment has become increasingly complex, which has gradually increased the probability of major oil spill pollution risks at sea. When a ship runs aground, sinks, or other accidents occur, the risk of oil spills increases greatly. It is an effective measure to promptly pump out the fuel from the accident ship and transfer it to other safe locations to prevent and reduce the damage caused by oil spills.
[0003] The general method of pumping oil from a distressed ship is: determine the location of the oil pumping - use the drilling equipment to drill a hole at the location of the oil pumping - connect the oil pumping equipment - pump the oil - seal. If the oil stored in the tank is in a solidified state due to oil quality, temperature and other reasons, the solidified oil needs to be heated during the oil pumping operation. Usually, the water inlet for underwater oil pumping is usually drilled underwater by a drilling machine, and then a water inlet and mud prevention device is installed at the hole. During the underwater oil pumping process, water can be effectively flowed into the tank to maintain the pressure balance inside and outside the tank. Summary of the invention
[0004] The technical problem to be solved by the utility model is to provide a water intake device for underwater oil extraction, which can prevent the oil in the sunken ship from flowing out of the ship and can also be used for cabin water intake to ensure the balance of internal and external pressure differences.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a water inlet device for underwater oil pumping, including connecting pipe one, connecting pipe two, a one-way valve and a mud cover, the two ends of the one-way valve are respectively connected to the ends of connecting pipe one and connecting pipe two, one end of connecting pipe two is connected to the one-way valve, and the other end is connected to the mud cover.
[0006] Preferably, one end of the connecting pipe is connected to the one-way valve, and the other end is provided with a connecting thread.
[0007] The technical solution of the utility model can achieve the following beneficial effects:
[0008] The underwater oil pumping water inlet device of the utility model is arranged on the detection pipe or directly on the hull. The device is used for water intake in the cabin to ensure the pressure difference between the inside and outside of the cabin is balanced when pumping oil, and at the same time can prevent the oil in the cabin from overflowing. The filtering device can also prevent mud and sand from entering the cabin when water is taken in. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] The following is a brief description of the contents and symbols in the drawings of this specification:
[0010] Figure 1 It is a structural schematic diagram of the device;
[0011] The markings in the above figures are: 1. connecting thread; 2. one-way valve; 3. connecting pipe 1; 4. mud cover; 5. connecting pipe 2. DETAILED DESCRIPTION
[0012] The following is a detailed description of the embodiments of the present invention, including the shapes and structures of the components involved, the relative positions and connection relationships between the components, the functions and working principles of the components, etc.
[0013] When an oil tanker runs aground, sinks, or other accidents occur, the risk of oil spills increases greatly. The fuel in the accident ship must be pumped out in time and transferred to other safe locations. During the oil pumping process, in order to maintain the pressure difference inside and outside the cabin of the sunken ship, water must be injected into the cabin to make the pressure difference inside and outside the cabin consistent. This device is used to allow water to enter the cabin, and at the same time prevent the fuel in the cabin from flowing back and overflowing.
[0014] like Figure 1 As shown, the water inlet device for underwater oil extraction comprises a connecting pipe 1 3, a connecting pipe 2 5, a one-way valve 2 and a mud cover 4. The two ends of the one-way valve 2 are respectively connected to the ends of the connecting pipe 1 3 and the connecting pipe 2 5. One end of the connecting pipe 2 5 is connected to the one-way valve 2, and the other end is connected to the mud cover 4. One end of the connecting pipe 1 3 is connected to the one-way valve 2, and the other end is provided with a connecting thread 1.
[0015] When in use, the connecting thread 1 of the device can be screwed onto the oil extraction detection pipe for water intake, or a threaded hole can be directly opened on the hull, and the connecting thread 1 can be directly screwed onto the threaded hole for water intake in the cabin. The mud cover 4 can prevent mud and sand from entering during the water intake process, and the one-way valve 2 can prevent oil from overflowing in the cabin, while also ensuring water intake.
[0016] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
