Description

Technical Field

[0001] This utility model relates to a surface seawater sampler, belonging to the field of seawater sampling technology. Background Technology

[0002] With the development of global industry, marine pollution has become increasingly serious, causing significant changes in the local marine environment. In order to understand the specific situation of seawater pollution, it is necessary to take seawater samples and bring them back to the laboratory for component analysis. Seawater sampling equipment is required when taking seawater samples.

[0003] When sampling surface seawater, there will be floating objects and plankton on the surface. However, commonly used seawater sampling methods cannot intercept and filter floating objects and plankton during use. This not only causes floating objects and plankton to clog the sampling device, but also the pollutants attached to the floating objects and plankton can affect the detection of seawater.

[0004] Therefore, there is an urgent need to improve the surface seawater sampler to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a surface seawater sampler that, through the design of a filtration sampling structure, can intercept and filter floating objects and plankton during the surface seawater sampling process. After filtration, the floating objects and plankton can be prevented from clogging the seawater and affecting the quality of seawater testing.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] A surface seawater sampler includes a floating platform frame, a winding roller fixedly mounted on the floating platform frame, a rope mounted on the winding roller, and a filtration sampling structure mounted on the rope. The filtration sampling structure includes a cover fixedly mounted on one end of the rope, a cylinder disposed below the cover, a pump fixedly mounted on the top of the cover, a fixing frame fixedly mounted on the pump, and a filter frame disposed on the fixing frame. The filter frame contains, from top to bottom, a glass fiber filter membrane, a polycarbonate filter membrane, and a nylon filter membrane.

[0008] Preferably, a solenoid valve is fixedly installed at the bottom of the cover, and the solenoid valve is connected to the output end of the pump.

[0009] Preferably, multiple fixing plates are fixedly installed on the surface of the fixing frame, bolts are installed on the fixing plates, and multiple threaded blocks are fixedly installed on the surface of the filter frame.

[0010] Preferably, the inner wall of the cover and the surface of the cylinder are both provided with threaded grooves, and multiple handles are fixedly installed on the cylinder.

[0011] Preferably, two support blocks are symmetrically arranged on both sides of the cylinder, and an underwater thruster is fixedly installed on the support blocks.

[0012] Preferably, two sealing frames are symmetrically fixedly installed on the cylinder, a motor is fixedly installed inside the sealing frame, a support rod connected to the support block is movably installed on one side of the sealing frame, and the output end of the motor is connected to the other end of the support rod.

[0013] Preferably, a liquid level sensor is fixedly installed on the inner wall of the cylinder, and an alarm electrically connected to the liquid level sensor is fixedly installed on the top of the floating platform frame.

[0014] This utility model has at least the following beneficial effects:

[0015] By setting up a filtration sampling structure, floating objects and plankton can be intercepted and filtered during the sampling of surface seawater. When the seawater is pumped out for sampling, the seawater passes through multiple layers of filtration and interception treatment of glass fiber filter membrane, polycarbonate filter membrane and nylon filter membrane in the filter frame, which can prevent floating objects and plankton from clogging the pump. At the same time, it can also prevent pollutants attached to floating objects and plankton from affecting the seawater testing. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5 As shown in the figure, this embodiment provides a surface seawater sampler embodiment.

[0025] A surface seawater sampler includes a floating platform frame 1, a winding roller 2 fixedly installed on the floating platform frame 1, a rope 3 installed on the winding roller 2, a filtration sampling structure 4 provided on the rope 3, the filtration sampling structure 4 including a cover 5 fixedly installed on one end of the rope 3, a cylinder 6 provided below the cover 5, a pump 7 fixedly installed on the top of the cover 5, a fixing frame 8 fixedly installed on the pump 7, a filter frame 9 provided on the fixing frame 8, and a glass fiber filter membrane 10, a polycarbonate filter membrane 11 and a nylon filter membrane 12 arranged sequentially from top to bottom inside the filter frame 9. By setting up the filtration sampling structure 4, floating objects and plankton can be intercepted and filtered during the sampling of surface seawater. After the winding roller 2 is started to loosen the rope 3 and lower the entire filtration sampling structure 4 into the seawater, the seawater is sampled by the pump 7. After the seawater passes through the glass fiber filter membrane 10, polycarbonate filter membrane 11 and nylon filter membrane 12 in the filter frame 9, the floating objects and plankton can be prevented from clogging the pump 7. At the same time, it also prevents the pollutants attached to the floating objects and plankton from affecting the seawater testing.

[0026] In this embodiment, as Figures 1-5As shown, a solenoid valve 13 is fixedly installed at the bottom of the cover 5. The solenoid valve 13 is connected to the output end of the pump 7. Multiple fixing plates 14 are fixedly installed on the surface of the fixing frame 8. Bolts 15 are installed on the fixing plates 14. Multiple threaded blocks 16 are fixedly installed on the surface of the filter frame 9. Threaded grooves 17 are opened on the inner wall of the cover 5 and the surface of the cylinder 6. Multiple handles 18 are fixedly installed on the cylinder 6. With the solenoid valve 13 in place, after seawater sampling is completed, the solenoid valve 13 is activated to seal the connection between the solenoid valve and the pump 7, preventing seawater leakage. With the fixing plate 14, bolts 15, and threaded blocks 16, the filter frame 9 is fixed to the fixing frame 8 by the connection of multiple bolts 15 and threaded blocks 16, so that the filter frame 9 can be removed from the fixing frame 8 by removing multiple bolts 15 from the threaded blocks 16. This facilitates the cleaning or replacement of the glass fiber filter membrane 10, polycarbonate filter membrane 11, and nylon filter membrane 12 after long-term use, avoiding clogging that affects filtration. With the threaded grooves 17 and the handle 18, the cover 5 and the cylinder 6 are connected by multiple threaded grooves 17, making the connection tighter and preventing them from falling off. It is also easy to disassemble and separate them to drain and collect seawater. At the same time, the handle 18 increases the force points on the surface of the cylinder 6, making it easier to twist and rotate the cylinder 6 during installation and disassembly.

[0027] In this embodiment, as Figures 1-5 As shown, two support blocks 19 are symmetrically arranged on both sides of the cylinder 6. An underwater thruster 20 is fixedly installed on the support block 19. Two sealing frames 21 are symmetrically fixedly installed on the cylinder 6. A motor 22 is fixedly installed inside the sealing frame 21. A support rod 23 connected to the support block 19 is movably installed on one side of the sealing frame 21. The output end of the motor 22 is connected to the other end of the support rod 23. A liquid level sensor 24 is fixedly installed on the inner wall of the cylinder 6. An alarm 25 electrically connected to the liquid level sensor 24 is fixedly installed on the top of the floating platform frame 1. With the support block 19, underwater thruster 20, sealing frame 21, motor 22, and support rod 23, the underwater thruster 20 on both sides of the cylinder 6 can push the cover 5 and the cylinder 6 as a whole into the seawater, avoiding floating on the surface, so as to better collect surface seawater samples. After sampling, the motor 22 can drive the support block 19 and the underwater thruster 20 to rotate and adjust the direction, so that when the cover 5 and the cylinder 6 are retrieved, the underwater thruster 20 can be activated to push the cylinder 6 for better recovery. The liquid level sensor 24 and the alarm 25 can be used to monitor the seawater sampling capacity in the cylinder 6 and the alarm 25 can be used to remind the operator to retrieve the cylinder 6 in time.

[0028] In this embodiment, as Figures 1-5 As shown, the working process of a surface seawater sampler provided in this embodiment is as follows:

[0029] After the take-up roller 2 is activated to loosen the rope 3 and lower the entire filter sampling structure 4 into the seawater, the seawater is sampled by the pump 7. The seawater passes through multiple layers of filtration and interception in the filter frame 9, including the glass fiber filter membrane 10, polycarbonate filter membrane 11, and nylon filter membrane 12. The filtered seawater enters the cylinder 6 for storage. After sampling, the pump 7 is turned off and the solenoid valve 13 is activated to close the connection with the pump 7 to prevent seawater leakage. Finally, the take-up roller 2 is activated to wind up the rope 3 and pull the entire filter sampling structure 4 outward. At the same time, the underwater propeller 20 assists the take-up roller 2 in retracting the filter sampling structure 4.

[0030] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
