Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of salvage equipment, in particular to a breathable cap tooling for oil extraction from a sunken ship. 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 breathable cap tooling for oil extraction from a sunken ship, which can inject water into the cabin while extracting oil, so as to keep the pressure difference between the inside and outside of the cabin balanced.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a breather cap tooling for oil extraction from a sunken ship, comprising a breather cap connecting flange, a manual valve, a quick connector, a water inlet pipe and a one-way valve, a circle of mounting holes being arranged on the breather cap connecting flange, the quick connector being fixedly mounted on the breather cap connecting flange, a manual valve being arranged on the quick connector, the water inlet pipe passing through the breather cap connecting flange, and a one-way valve being arranged on the water inlet pipe.
[0006] Preferably, a circle of rubber sealing gasket is provided on the bottom edge of the vent cap connecting flange to play a sealing role.
[0007] Preferably, a filter screen is provided on the top of the water inlet pipe.
[0008] The technical solution of the utility model can achieve the following beneficial effects:
[0009] The utility model discloses a breathable cap tooling for oil extraction from a sunken ship, which is installed on the cabin of the sunken ship for extracting oil and taking in water. The device replenishes water into the cabin while extracting oil, thereby ensuring the pressure difference between the inside and outside of the cabin is balanced when extracting oil, and can prevent oil in the cabin from overflowing. The filter net provided can also prevent mud and sand from entering the cabin when taking in water. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] The following is a brief description of the contents and symbols in the drawings of this specification:
[0011] Figure 1 This is the structural diagram of this tooling;
[0012] The markings in the above figures are: 1. Breathable cap connecting flange; 2. Quick connector; 3. Manual valve; 4. Water inlet pipe; 5. Check valve; 6. Rubber sealing gasket; 7. Filter. DETAILED DESCRIPTION
[0013] 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.
[0014] 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.
[0015] like Figure 1 As shown, the breather cap tooling for oil extraction from a sunken ship comprises a breather cap connecting flange 1, a manual valve 3, a quick connector 2, a water inlet pipe 4 and a one-way valve 5. A circle of mounting holes is arranged on the breather cap connecting flange 1, and the mounting holes are used to install the tooling to the surface of the cabin of the sunken ship. The quick connector 2 is fixedly mounted on the breather cap connecting flange 1, and a manual valve 3 is arranged on the quick connector 2. The quick connector 2 is used to quickly connect the oil extraction pipe, and the manual valve 3 is used to control the flow rate and switch of the oil extraction. The water inlet pipe 4 runs through the breather cap connecting flange 1, and a one-way valve 5 is arranged on the water inlet pipe 4. The one-way valve 5 can only allow water to enter the cabin, and does not allow the oil in the cabin to overflow.
[0016] like Figure 1 As shown, a circle of rubber sealing gasket 6 is arranged at the bottom edge of the breathable cap connecting flange 1 to play a sealing role. During installation, the breathable cap connecting flange 1 is fixed to the cabin surface by screws. The rubber sealing gasket 6 plays a sealing role. A filter screen 7 is arranged on the top of the water inlet pipe 4 to prevent mud and sand from entering when water is entering.
[0017] When in use, the tool is installed on the cabin wall, and then the oil extraction pipe is connected to the quick connector 2, and the manual valve 3 is opened to start oil extraction. While pumping oil, as the pressure difference between the inside and outside of the cabin changes, water is sucked into the water inlet pipe 4 and enters the cabin through the water inlet pipe 4, so that the pressure difference between the inside and outside is balanced. The setting of the one-way valve 5 can prevent the oil in the cabin from overflowing, and the setting of the filter screen 7 can also prevent mud and sand from entering the cabin when water is taken in.
[0018] 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.
