Description

Technical Field

[0001] This invention relates to the field of oil spill recovery equipment technology, and in particular to an oil spill recovery device and recovery method for use in a small marine area. Background Technology

[0002] Oil spills refer to the leakage of oil products during offshore oil exploration, production, storage, and transportation due to various reasons. With the booming development of the maritime transportation industry and the frequent comings and goings of ships, the probability of marine pollution is constantly increasing. At the same time, seabed oil extraction also brings oil pollution to the sea surface, making marine environmental pollution increasingly serious and causing serious harm to the world's ecological environment.

[0003] Currently, the main methods for recovering marine oil spills include physical, chemical, and biological methods. Among these, physical methods have the least environmental pollution, as they can separate oil from water without altering the chemical properties of the crude oil. These methods include mechanical recovery or the use of adsorbent materials to recover the spilled oil. However, there are no mature devices available for oil spills in confined areas, as the limited distance and area prevent these devices from entering the spill zone for oil recovery. Summary of the Invention

[0004] The technical problem to be solved by this invention is that there is no mature device for oil spills in small areas. Due to the small distance and range, the device cannot enter the leak area to recover the oil spill. This invention provides an oil spill recovery device and method for small sea areas.

[0005] The technical solution adopted by this invention to solve its technical problem is: an oil spill recovery device for confined sea areas, comprising a device body that can float on the sea surface, oil-absorbing foam for absorbing oil spills, a squeezing mechanism for squeezing the oil-absorbing foam, and a control unit. The device body is provided with a power mechanism for controlling its displacement on the sea surface. The device body is provided with a launching mechanism for launching the oil-absorbing foam to the oil spill area. The device body is provided with a recovery mechanism for recovering the oil-absorbing foam. The output end of the recovery mechanism is sequentially provided with an aligning mechanism, a conveying mechanism, and an oil storage mechanism. The aligning mechanism is used to align and sort the oil-absorbing foam recovered by the recovery mechanism and convey it to the conveying mechanism. The conveying mechanism is used to output the oil-absorbing foam aligned by the aligning mechanism to the oil storage mechanism. The device body is provided with a displacement mechanism for controlling the reciprocating movement of the squeezing mechanism between the launching mechanism and the oil storage mechanism. The control unit is signal-connected to the power mechanism, the launching mechanism, the recovery mechanism, the oil storage mechanism, the displacement mechanism, and the squeezing mechanism.

[0006] In some preferred embodiments, the launching mechanism includes a launching pipe disposed on the device body, and a discharge pump is installed on the launching pipe for launching oil-absorbing foam in the launching pipe to the oil spill area.

[0007] In some preferred embodiments, the recovery mechanism includes a recovery pipeline disposed on the device body, and a recovery pump is installed on the recovery pipeline for recovering oil-absorbing foam from the oil spill area through the recovery pipeline.

[0008] In some preferred embodiments, the launch pipe and the recovery pipe are arranged side by side.

[0009] In some preferred embodiments, the extrusion mechanism includes an extrusion plate disposed on the extended end of a robotic arm. The robotic arm is used to move the extrusion plate closer to or away from the oil-absorbing foam, and to control the extrusion plate to grab the oil-absorbing foam for extrusion or release of the oil-absorbing foam.

[0010] In some preferred embodiments, the displacement mechanism includes a pulley mechanism rotatably mounted on the device body, and the manipulator is mounted on the pulley mechanism.

[0011] In some preferred embodiments, the oil-absorbing foam is provided with a positioning module and a detection module. The positioning module and the detection module are respectively connected to the control unit. The positioning module is used to locate the specific position of the oil-absorbing foam, and the detection module is used to detect the oil concentration of the oil-absorbing foam.

[0012] In some preferred embodiments, the extrusion plate is provided with a receiving cavity, which is used to avoid the positioning module and detection module on the oil-absorbing foam and to prevent being clamped to the positioning module and detection module.

[0013] In some preferred embodiments, the oil storage mechanism includes an oil storage tank and an oil pump. The output end of the conveying mechanism is provided with a placement trough for placing oil-absorbing foam. The oil storage tank is located below the placement trough and is interconnected with it. The oil pump is located between the oil storage tank and the placement trough.

[0014] A recovery method using an oil spill recovery device in a confined marine area as described above includes the following steps:

[0015] S1. The control unit sends a signal to the displacement mechanism and the squeezing mechanism. The displacement mechanism drives the squeezing mechanism to move to the location of the oil-absorbing foam, controls the squeezing mechanism to approach and grab the oil-absorbing foam, and then the displacement mechanism drives the grabbing mechanism to move to the launching mechanism to place the oil-absorbing foam in the launching mechanism.

[0016] S2. The control unit sends a signal to the launching mechanism and launches the oil-absorbing foam into the oil spill area;

[0017] S3. Following steps S1 and S2, launch multiple oil-absorbing foams in sequence;

[0018] S4. The detection module monitors the oil absorption concentration of the oil-absorbing foam in real time. When the oil absorption concentration is reached, the control unit controls the power mechanism according to the specific position of the positioning module on the oil-absorbing foam to move the device body to the position of the oil-absorbing foam.

[0019] S5. The control unit sends a signal to the recycling mechanism and recycles the oil-absorbing foam.

[0020] S6. The recovered oil-absorbing foam passes through the sorting mechanism, the conveying mechanism and the oil storage mechanism in sequence;

[0021] S7. The control unit controls the squeezing mechanism to grab and squeeze the oil-absorbing foam. The oil storage mechanism stores the squeezed-out oil. The squeezed oil-absorbing foam is sent to the launching mechanism through the displacement mechanism and then launched to the oil spill area.

[0022] The beneficial effects of the present invention are as follows: When the present invention provides an oil spill recovery device and method for use in a narrow sea area, the device reasonably solves the problem of oil recovery being affected by factors such as distance, range, and viscosity, improves the purity of oil recovery, improves the efficiency of oil recovery, and solves the problem that there is no mature device for oil spills in narrow areas, and the device cannot enter the leak area to recover oil spills due to the small distance and range.

[0042] Example 2

[0043] Example 2 is a recovery method based on Example 1, specifically: a recovery method using an oil spill recovery device for a small sea area as described above, comprising the following steps:

[0048] S5, Control Unit 4 sends a signal to the recycling pump 702 of the recycling mechanism 7 and recycles the oil-absorbing foam 2 through the recycling pipe 701;

[0049] S6. The multiple oil-absorbing foams 2 that have been recovered are sorted and arranged by the arranging mechanism 8, and then transported by the conveying mechanism 9 to the placement tank 1003 above the oil storage mechanism 10.

[0050] S7, the control unit 4 controls the squeezing mechanism 3 to grab the oil-absorbing foam 2 and squeeze it. The squeezed oil is transported to the oil storage tank 1001 by the oil pump 1002 below the placement tank 1003, so that the oil storage mechanism 10 can store the squeezed oil spill. The squeezed oil-absorbing foam 2 is sent to the launching mechanism 6 through the displacement mechanism 11 and continues to be launched to the oil spill area.
