Description

Technical Field

[0001] This utility model relates to the field of seawater detection technology, and in particular to an online detection device for oil pollution in marine water. Background Technology

[0002] Currently, offshore oilfield extraction technology is becoming increasingly advanced. During offshore operations, oil spills are inevitable. If oil spills from offshore drilling platforms are not cleaned up promptly or spread elsewhere by ocean currents, they can cause serious ecological pollution. Furthermore, in densely populated urban areas with rivers flowing into the sea, large amounts of domestic sewage and various vessels contribute to marine oil pollution, resulting in a precarious marine environment. Therefore, online detection of offshore oil spills is of great significance for environmental protection, pollution incident response, and marine resource management.

[0003] When using optical absorption sensors to detect oil spills at sea, a collection container is needed to collect seawater. Inside the container, a stable light source (such as an LED or laser) emits a beam of light of a specific wavelength. The optical absorption sensor, positioned at the opening of the container, receives the light intensity after passing through the seawater sample and records the changes in transmitted light. Then, based on the degree of light intensity attenuation and a pre-established standard curve, the oil concentration is calculated—in other words, the oil concentration is determined by measuring the change in light intensity passing through the water sample. However, during use, the inner wall of the collection container needs to be kept clean, as oil adhering to the inner wall can affect the accuracy of the detection results. Since timely cleaning is not possible at sea, this method is quite inconvenient. Utility Model Content

[0023] Example:

[0024] Reference Figures 1-4 An online oil spill detection device for marine water includes a base 1 and a floating hull 101 fixed to the bottom of the base 1. An anchor chain is fixedly installed on the bottom side of the base 1 near the floating hull 101, which can be placed in waterways, estuaries, or oil drilling platforms. The floating hull 101 consists of two sets of symmetrical floating bodies. The shape of the floating bodies is similar to a ship-shaped structure. That is to say, when floating freely at sea, under the action of ocean currents, the bow of the ship-shaped floating hull 101 can always face the upstream direction of the water flow. The floating bodies adopt a streamlined design to reduce water resistance. This design makes the floating bodies more inclined to point the bow towards the direction of the water flow in the water. It also includes: a fixing plate 2 fixedly installed at the bottom of the base 1, a rotating shaft 201 rotatably installed on the fixing plate 2, and at least one set of collecting cylinders 202 fixedly installed on the rotating shaft 201. Here, we preferably provide two sets of collecting cylinders 202, which are evenly distributed circumferentially on the rotating shaft 201, and the axis of the collecting cylinders 202 is perpendicular to the axis of the rotating shaft 201. In use, the rotation of the rotating shaft 201 can automatically collect seawater with the collecting cylinders 202. After the test is completed, the collected seawater can be poured back into the ocean, similar to a waterwheel structure. A detection unit for detecting oil contamination in the sample is provided on the base 1. The detection unit can detect the oil contamination in the collecting cylinders 202. The samples collected in container 02 are tested for oil contamination. A water outlet pipe 501 is fixedly installed on the fixed plate 2. A nozzle 503 for cleaning the inner wall of the collection cylinder 202 is fixedly installed at one end of the water outlet pipe 501. The nozzle 503 is positioned in the collection cylinder 202, which is used for pouring seawater. That is, when the rotating shaft 201 stops rotating and the detection unit is performing the detection, the axis of the nozzle 503 coincides with the axis of the collection cylinder 202, which is used for pouring seawater. In use, the cleaning liquid in the storage tank 103 is pumped away by the water pump 5 and delivered to the nozzle 503. The nozzle 503 can clean the inside of the collection cylinder 202 where seawater is poured, thus improving the effectiveness of use.

[0025] In use, by setting multiple workstations on the rotating shaft 201 to form a collection cylinder 202, and fixing a nozzle 503 on the fixed plate 2 for cleaning the collection cylinder 202 at the seawater dumping workstation, the inner wall of the collection cylinder 202 can be cleaned in time after the test, reducing the oil stains adhering to the inner wall of the collection cylinder 202 and improving the accuracy of the test results.

[0026] Reference Figures 1-3A pyramidal shell 102 is fixedly installed on the top of the base 1. Preferably, the shell 102 is an octagonal pyramid. A storage tank 103 for storing cleaning fluid is fixedly installed inside the shell 102. The cleaning fluid can be a plant-based cleaner, an enzyme-based cleaner, or a marine-environmentally friendly cleaner, preferably a marine-environmentally friendly cleaner, mainly used in marine environments. The formula contains rapidly biodegradable surfactants and other environmentally friendly ingredients, which can effectively remove salt and oil stains. Moreover, it does not easily produce a large amount of foam in water, making it easy to rinse and reducing the residue of cleaning fluid in the collection cylinder 202. A water pump 5 is fixedly installed inside the shell 102. The other end of the water outlet pipe 501 is connected to the water pump 5, and the other end of the water pump 5 is connected to the storage tank 103 through the water inlet pipe 502. In use, the cleaning fluid in the storage tank 103 is drawn away by the water pump 5 and delivered to the nozzle 503 through the water outlet pipe 501 to clean the inner wall of the collection cylinder 202.

[0027] Reference Figure 3 Multiple sets of partitions 104 are fixedly installed inside the liquid storage tank 103. There are two to ten sets of partitions 104, preferably eight sets. Channels are opened on the partitions 104, and a liquid filling pipe connected to the liquid storage tank 103 is fixedly installed on the housing 102. A pipe cap is threadedly connected to the liquid filling pipe. In use, by fixing the partitions 104 inside the liquid storage tank 103, the impact on the housing 102 during shaking can be reduced, and the swaying of the housing 102 can be reduced.

[0028] Reference Figures 1-3 A solar panel is fixedly installed on the outer wall of the housing 102, and the solar panel is fixed on the side of the pyramid. A rechargeable battery is fixedly installed inside the housing 102, and a control module is fixedly installed inside the housing 102. The control module is existing technology, and its main functions include controlling and coordinating the working status of the water pump 5 and the motor 4, and then implementing wireless communication to facilitate the transmission of detection data. The control module and the solar panel are electrically connected to the rechargeable battery, and the detection unit and the water pump 5 are electrically connected to the control module to facilitate control and improve the use effect.

[0029] Reference Figure 3 and Figure 4Here, the detection unit is designed with a detection seat 3 that is raised and lowered inside the base 1. An installation groove is provided at the bottom of the detection seat 3, and an optical absorption sensor 301 is fixedly installed at the top of the installation groove. The bottom of the detection seat 3 is abutted against the liquid inlet end of the collection cylinder 202 by a rubber pad, which can reduce the interference of external light. Moreover, the inner and outer walls of the collection cylinder 202 are fixedly coated with an opaque coating, and a light source 203 matching the optical absorption sensor 301 is fixedly installed at the bottom of the collection cylinder 202. The light source 203 and the optical absorption sensor 301 are electrically connected to the control module. In use, the seawater is collected by rotating the collection cylinder 202. When the collection cylinder 202 rotates to the detection position, the rotating shaft 201 stops rotating. At this time, the detection seat 3 slides down, and the rubber pad at the bottom abuts against the liquid inlet end of the collection cylinder 202. Then, the light source 203 and the optical absorption sensor 301 are activated to detect oil pollution in the seawater.

[0030] Reference Figure 4 A motor 4, electrically connected to the control module, is fixedly mounted on the top of the base 1. A second synchronous pulley 401 is fixedly mounted on the output end of the motor 4. A first synchronous pulley is fixedly mounted on the rotating shaft 201. The first and second synchronous pulleys 401 are meshed together by a synchronous belt. Since the collecting cylinder 202 has three sets of equally spaced components, the first synchronous pulley rotates one-third of a turn for every one revolution of the second synchronous pulley 401. A rotating plate 302 is fixedly mounted on the top of the detection seat 3, and a connecting rod is rotatably mounted on the rotating plate 302. 402. An eccentric shaft is fixedly installed on the end face of the second synchronous pulley 401. The end of the connecting rod 402 away from the rotating plate 302 is rotatably connected to the eccentric shaft. In use, the second synchronous pulley 401 is driven to rotate by the motor 4. It can drive the rotating shaft 201 and the collection cylinder 202 to rotate through the synchronous belt and the first synchronous pulley, which facilitates the changing of the three sets of collection cylinders 202. In this process, the second synchronous pulley 401 can drive the detection seat 3 to rise and fall through the eccentric shaft and the connecting rod 402. The structure is simple, the driving effect is reliable, and the use effect is improved.
