Description

Technical Field

[0001] The utility model relates to the technical field of marine oil slick sampling, in particular to a marine oil slick sampling device. Background Art

[0002] Oil is a viscous, dark brown liquid. The extraction of oil on Earth includes the interior of the surface and the interior of the ocean. When oil is extracted from the interior of the ocean, a certain amount of marine oil slicks will be produced. Oil slick literally means an oily substance floating on the water. Oil slicks floating on the sea surface are harmful to humans and the environment. They will hinder the photosynthesis of plankton at the bottom of the food chain, reduce the dissolved oxygen content in seawater, and cause the death of a large number of marine organisms. Marine organisms such as fish are particularly susceptible to oil slicks in the early stages of development. They will accumulate along the food chain and threaten food safety. When detecting oil slicks in the ocean, sampling devices are often required to collect samples of the oil slicks.

[0003] The Chinese patent with the existing authorization announcement number (CN219977845U) discloses a water body oil floating sampler, including a base, a connecting rod fixed to one side of the top of the base, a portable structure provided at the top of the horizontal plate, the portable structure including a reserved groove, the reserved groove provided inside the top of the horizontal plate, a connecting column provided inside the reserved groove, a fixing plate fixed to the top of the connecting column, and a handle fixed to the top of the fixing plate. During use, this utility model is provided with a portable structure, the notch at the top of the reserved groove enables the connecting column to be engaged with the inside of the reserved groove, grasp the handle and rotate it, so that the connecting column rotates inside the reserved groove and slides to the other side of the reserved groove, so that the connecting column can be engaged with the inside of the reserved groove, so that the fixing plate can be fixed to the top of the horizontal plate, grasp the handle and lift it, so that the water body oil floating sampler can be lifted, thereby realizing the portable taking of the water body oil floating sampler, and it can be disassembled and assembled at the same time, and it is convenient to use.

[0004] However, this utility model is not convenient for multi-point sampling. When it is necessary to sample oil spills at multiple locations, the water body oil spill sampler must be disassembled and then replaced with a new water body oil spill sampler. The whole process is time-consuming and can easily affect the efficiency of multi-point sampling of oil spills.

[0005] In order to solve the above problems, we propose a marine oil spill sampling device to solve the above problems. Utility Model Content

The pressing needle is pushed by the telescopic rod so that the pressing needle can press the sealing plug. By pressing the pressing needle to the inner side of the feed port and leaking out of the inlet of the feed pipe, the floating oil will flow in from the feed port and then flow into the sampling tube through the feed tube in turn for collection. When the sealing plug loses the pressure of the pressing needle, the sealing plug will return to the feed port to seal the feed port under the push of the elastic force of the spring, so as to avoid the overflow of the floating oil collected in the sampling tube. At the same time, it also prevents the floating oil from other places from flowing in and polluting the previously sampled floating oil.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] In the present solution, the rotating shaft is driven to rotate by a motor so that multiple groups of sampling tubes can be moved to the middle position of the bottom end of the pressing needle in sequence, and then the pressing needle is pushed by the telescopic rod to press and move the pressing needle against the sealing plug, thereby facilitating the floating oil to flow into the sampling tube through the feed port for collection. Conversely, the pressing needle is driven to retract by the telescopic rod, and the pressure of the pressing needle is lost. The sealing plug re-seals the feed port under the push of the spring, thereby preventing floating oil from other locations from entering the sampling tube and causing pollution. Through the above process, the utility model allows the sampling device to perform multi-point sampling in sequence, and the entire sampling process does not require repeated disassembly and replacement of the sampling tube, effectively improving the sampling work efficiency and solving the problems raised by the background technology.

DETAILED DESCRIPTION

[0021] The embodiment of the present application provides a marine oil spill sampling device, which provides a technical solution that can perform multi-point sampling of sea surface oil spills in sequence. Moreover, the entire sampling process does not require repeated disassembly and replacement of the sampling tube 11. The operation is simple, convenient and fast, and the sampling work efficiency is effectively improved.

[0022] Example: Refer to Figure 1-3 As shown, a marine oil floating sampling device of this embodiment includes a fixed base 1, a rotating shaft 2 is arranged in the middle of the bottom end of the fixed base 1, the rotating shaft 2 is driven to rotate by a motor, a base 5 is arranged in the middle of the bottom end of the rotating shaft 2, and a sampling assembly is arranged in the middle of the upper end of the base 5; the sampling assembly includes multiple groups of sampling tubes 11, and the rotating shaft 2 is driven to rotate by the motor, so that the multiple groups of sampling tubes 11 can rotate.

[0023] The upper end of the sampling tube 11 is threadedly connected with a top cover 12, a feed port 14 is arranged in the middle of the upper end of the top cover 12, a sealing plug 15 is movably installed in the middle of the inner side of the feed port 14, a spring 16 is arranged in the middle of the bottom end of the sealing plug 15, and the bottom of the spring 16 is fixedly installed in the middle of the inner side of the top cover 12; both sides of the bottom end of the feed port 14 are connected with feed pipes 17, the feed pipes 17 are located in the middle of both ends of the sealing plug 15, and the bottom end of the feed pipe 17 is connected with the sampling tube 11; the sampling assembly also includes a pressing needle 10, a telescopic rod 9 is arranged in the middle of the top end of the pressing needle 10, and the base of the telescopic rod 9 is fixedly installed on one side of the bottom end of the fixed seat 1.

[0024] Among them, the pressing needle 10 can be pushed by extending the telescopic rod 9, and the sealing plug 15 can be pressed by the pressing needle 10, so that the sealing plug 15 moves downward, thereby leaking out the inlet of the feed pipe 17. At this time, the floating oil on the sea surface can flow in from the feed port 14, and then flow into the sampling tube 11 through the feed pipe 17 in turn.

[0025] When the pressing needle 10 is retracted to the initial position by the telescopic rod 9, the sealing plug 15 loses the pressure of the pressing needle 10 and is pushed by the elastic force of the spring 16 to return to the position of the feed port 14, thereby sealing the feed port 14 and preventing floating oil from overflowing from the sampling tube 11.

[0026] A plurality of mounting holes 6 are arranged around the upper end of the base 5, and the plurality of mounting holes 6 are distributed in a circular array. A threaded seat 13 is arranged in the middle of the bottom end of the sampling tube 11, and the threaded seat 13 is threadedly connected to the mounting holes 6, thereby improving the stability of the sampling tube 11 during installation and preventing the sampling tube 11 from falling when used in seawater.

[0027] A limit plate 3 is provided in the middle of the bottom end of the rotating shaft 2, and the limit plate 3 is located in the middle of the upper end of the base 5. A plurality of groups of through holes 4 are provided in the middle of the inner side of the limit plate 3, and the through holes 4 are located at the upper end of the mounting hole 6 and correspond to the position of the mounting hole 6. The sampling tube 11 passes through the through holes 4 and extends out. The limit plate 3 limits the sampling tube 11, thereby further improving the stability of the sampling tube 11 during installation.

[0028] Limiting blocks 18 are provided at both ends of the inner side of the feed port 14 , and the limiting blocks 18 can limit the sealing plug 15 to prevent the sealing plug 15 from sliding out from the inlet end of the feed port 14 under the push of the spring 16 .

[0029] In some examples, a connecting column 7 is provided in the middle of the upper end of the fixing seat 1, and a flange 8 is provided in the middle of the top end of the connecting column 7 for installing and fixing the sampling device.

[0030] In some examples, the bottom end of the base 5 is configured to be tapered.

[0031] The working principle of the utility model is:

[0032] When it is necessary to collect samples of oil spills on the ocean, the sampling device is first mounted on a long pole or a retractable device through a flange 8. After the sampling device is moved to a designated location, the sampling device is first dropped onto the oil spill surface through the long pole or the retractable device, so that the oil spill submerges the sampling tube 11.

[0033] At this time, the motor is driven to drive the rotating shaft 2 to rotate, so that one of the sampling tubes 11 rotates and moves to the middle of the bottom end of the pressing needle 10, and then the pressing needle 10 is pushed by the telescopic rod 9, so that the pressing needle 10 is pushed downward to contact the sealing plug 15, and the pressing needle 10 continues to press downward to push the sealing plug 15. When the sealing plug 15 slides down to the inside of the feed port 14, the feed pipe 17 leaks out. At this time, the floating oil on the sea surface will flow in from the feed port 14, and then flow into the sampling tube 11 through the feed pipe 17 for collection;

[0034] When the sampling tube 11 collects enough floating oil, the telescopic rod 9 is retracted to drive the pressing needle 10 to move upward. At this time, the pressure of the pressing needle 10 is lost, and the sealing plug 15 slides upward under the push of the spring 16, thereby sealing the feed port 14 again.

[0035] When sampling is required at another sampling point, the motor is only required to drive the rotating shaft 2 to rotate, rotate and move a new sampling tube 11 to the bottom of the pressing needle 10, and then repeat the above operation.

[0036] Through the above process, the sampling device can perform multi-point sampling in sequence, and the entire sampling process does not require repeated disassembly and replacement of the sampling tube 11, which effectively improves the sampling work efficiency.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
