Description

Technical Field

[0001] The utility model belongs to the technical field of marine oil spill recovery equipment, in particular to a marine oil spill recovery and dragging integrated device. Background Art

[0002] Petroleum is a fluid mineral buried deep underground. The pollution caused by petroleum and its refined products entering the marine environment during the process of extraction, refining, storage, transportation and use is a serious marine pollution in the world. Its prevention and control must rely on global cooperation to be more effectively achieved. Various oily wastewaters, the discharge of ballast water and tank washing water of offshore ships, or the leakage of oil tankers in distress, oil pipelines and offshore oil production are all ways of marine oil pollution. After entering the sea, a series of changes immediately occur, including diffusion, evaporation, dissolution, emulsification, photochemical oxidation, microbial degradation, sedimentation, formation of asphalt balls, etc. The oil film on the sea surface can hinder the gas exchange between the atmosphere and seawater, affect the photosynthesis of marine plants, and cause marine pollution.

[0003] After searching, the patent with publication number CN116356773A discloses an integrated device for recovering and towing oil spills in the ocean, including a towing boat, an oil storage tank fixedly connected inside the towing boat, a water pump installed on the top of the oil storage tank, and an encoder fixedly connected on the top of the water pump. The integrated device for recovering and towing oil spills in the ocean enables the hydraulic cylinder inside the short bend pipe to push the extrusion plate to squeeze the oil-absorbing cotton, and guide the oil spills collected by the oil-absorbing cotton into the oil tank through the flaring pipe, the solenoid valve that is opened for work, and the oil discharge pipe. The oil-absorbing cotton that absorbs and collects the oil spills can be squeezed and cleaned regularly to avoid the situation where the oil spills are absorbed by the oil-absorbing cotton too much, resulting in a decrease in the quality of the oil spill filtration and interception, thereby ensuring the clean recovery of the oil spills and ensuring the clean and fast recovery of the oil spills that cause marine pollution.

[0004] The above patent absorbs the spilled oil through oil-absorbing cotton and separates the spilled oil from seawater. The oil-absorbing cotton that intercepts the spilled oil can be driven by the waterproof motor and the drive shaft to rotate between the short bend pipe and the oil discharge pipe, so that the hydraulic cylinder inside the short bend pipe pushes the extrusion plate to squeeze the oil-absorbing cotton, and the spilled oil collected by the oil-absorbing cotton passes through the flared pipe. Since seawater is easily retained in the oil-absorbing cotton, it is difficult to separate it from the seawater completely. In addition, during the squeezing process of the oil-absorbing cotton, the oil in the oil-absorbing cotton is easy to flow back into the ocean, affecting the effect of oil spill recovery. Summary of the invention

[0005] The utility model aims to provide an integrated device for recovering and dragging marine oil spills, so as to solve the problems raised by the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an integrated towing device for recovering and towing oil spills in the ocean, comprising a towing boat, a box and a pumping pipe, wherein a box is arranged on the inner side of the towing boat, a filter is arranged on the bottom end of the box, a pumping pipe extending to the outside of the towing boat is arranged on one side of the filter, a water pump connected to the filter is installed on the bottom end of the box by bolts, an oil storage tank is arranged on one side of the box on the inner side of the towing boat, a filter cover is connected to one end of the pumping pipe by bolts, a weight block is welded to the outer wall of one end of the pumping pipe, and a balance plate is welded to the outer wall of the weight block.

[0007] Preferably, four groups of threaded rods are sleeved through the interior of the balance board, nuts are sleeved on the outer walls of the threaded rods, and air bags are arranged on the top ends of the threaded rods.

[0008] Preferably, the output end of the water pump is provided with a water tank connected to the bottom end of the box body, and the top end of the water tank is provided with multiple groups of water spray pipes extending to the inside of the box body.

[0009] Preferably, an upper fixing plate is welded to the top of the box body, a lower fixing plate is welded to the bottom end of the box body on one side of the upper fixing plate, a drainage box is arranged inside the box body, and a drainage pipe extending to the outside of the box body is arranged inside the drainage box.

[0010] Preferably, a filter element is arranged inside the filter.

[0011] Preferably, a connecting pipe extending to the interior of the box body is provided inside the oil storage box, and an oil drain port is provided on one side of the oil storage box.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When the utility model is used to recover the oil spill floating on the seawater, the buoyancy of the airbag drives the threaded rod, the balance plate, the weight block and one end of the water pumping pipe to float up, so that the filter cover is half-sunk in the sea surface, and the seawater containing oil on the sea surface is pumped into the inside of the water pump through the filter, the water pump and the water pump, and the seawater containing oil is sprayed into the inside of the box through the water pump, the water tank and the water spraying pipe. Since the density of the oil is less than that of the seawater, the seawater containing oil forms a layer on the inner side of the upper fixed plate and the lower fixed plate, the oil floats up, and the seawater sinks. The seawater containing oil continues to enter the inside of the box, so that the oil flows through the top of the lower fixed plate to the other side of the lower fixed plate for storage, and the seawater enters one side of the upper fixed plate through the bottom end of the upper fixed plate, and the excess seawater is discharged through the drainage box and the drainage pipe. The oil enters the inside of the oil storage tank through the connecting pipe for storage, and the water mixed in the oil is deposited on one side of the lower fixed plate. The utility model reduces the content of seawater in the recovered oil and improves the purity of the recovered oil.

[0014] 2. The utility model blocks large particles of impurities in the pumped seawater through the filter cover, and filters the seawater containing oil through the filter element, thereby ensuring the quality of the recovered oil. BRIEF DESCRIPTION OF THE DRAWINGS
