Description

Technical Field

[0001] This invention relates to the field of marine biofouling testing technology, specifically to a marine biofouling testing platform device. Background Technology

[0002] A large number of marine organisms in seawater adhere to seawater pipes, causing the pipe diameter to shrink, resulting in insufficient flow. This also accelerates the deterioration and corrosion of the pipes, reducing equipment reliability and lifespan. Furthermore, large-scale shedding of the attached marine organisms can clog the pipes. Therefore, many new antifouling technologies have emerged. To ensure the effectiveness of these technologies, testing is necessary.

[0003] Chinese invention patent CN113777230A discloses a marine biofouling test bench device and method, including a water inlet tank. One side of the water inlet tank has a seawater intake pipe, and the other side has a test channel. The test channel includes a blank test tube section and a test tube section module. Both the blank test tube section and the test tube section module include a flow measurement device. The inner bottom wall of the water inlet tank has an overflow weir plate and a grid, with the grid located on the side of the overflow weir plate away from the seawater intake pipe. However, this solution has the following drawbacks: the grid is installed inside the water inlet tank to intercept larger substances in the seawater, but it is inconvenient to clean up the intercepted larger substances; the device is large in size due to its composition of the water inlet tank, concrete channel, and tailrace pool, making assembly inconvenient; after the test plate is inserted into the concrete channel, contact with the test plate is required when removing it, which can easily cause marine organisms on the surface of the test plate to fall off, affecting the accuracy of the test results.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 5 This invention provides a technical solution: a marine biofouling antifouling test bench device, comprising a water inlet tank 1 and a test chamber 2. A first connecting pipe 6 and a second connecting pipe 7 are installed between the water inlet tank 1 and the test chamber 2 via a fixing mechanism 5. The fixing mechanism 5 includes a slider 15, a screw 14, and a pressing plate 16. A water inlet pipe 3 is movably installed on one side of the top of the water inlet tank 1 via a U-shaped frame. The water inlet pipe 3 is movably installed on the inner side of the U-shaped frame via a torsion spring shaft. The U-shaped frame is fixedly installed on the outer wall of the top of the water inlet tank 1. A filter frame 4 is installed below the water inlet pipe 3, with one end of the filter frame 4 snapped onto the top of the water inlet tank 1. The test chamber 2 has four flow channels 8 inside. The top of the test chamber 2 is longitudinally fixed... A horizontal plate 9 is fixedly provided, and a test plate 20 is provided at the bottom of the horizontal plate 9 through a placement mechanism 10. The placement mechanism 10 includes a placement opening 17, which is equidistantly opened inside the horizontal plate 9. A vertical plate 19 is slidably provided inside the placement opening 17, and a groove is opened at the bottom end of the vertical plate 19. The test plate 20 is vertically fixedly installed inside the groove. The water inlet pipe 3 can limit the filter frame 4 under the action of the torsion spring shaft, which facilitates the filtration of larger impurities in seawater through the filter frame 4. Furthermore, the filter frame 4 can be easily disassembled to clean the impurities inside the filter frame 4. By installing the test plate 20 inside the groove, it is easy to prevent the test plate 20 from contacting the horizontal plate 9 when the test plate 20 is removed, thus avoiding the marine organisms that should be prevented from falling off the test plate 20 and ensuring the accuracy of the test structure.

[0023] In this embodiment, a limiting plate 18 is fixedly installed on the top of the vertical plate 19. The limiting plate 18 is located above the placement opening 17 and the horizontal plate 9. A gap is provided between the test plate 20 and the inner walls of the front and rear sides of the groove. The bottom of the test plate 20 is flush with the bottom of the vertical plate 19. The test plate 20 is located inside the flow channel 8. The interaction between the vertical plate 19 and the placement opening 17 can limit the test plate 20, thereby ensuring the stability of the test plate 20 during the lowering and pulling process. In addition, the groove can ensure that the test plate 20 does not come into contact with other objects.

[0024] In this embodiment, an installation groove is provided inside one end of the water inlet tank 1 and the test chamber 2. The slider 15 is slidably installed inside the installation groove via a screw 14. The screw 14 is screwed to the top of the installation groove, and a handwheel 21 is fixedly installed on the top of the screw 14. The handwheel 21 is located on the top of the water inlet tank 1 and the test chamber 2. The screw 14 is rotatably located at the center position of the top of the slider 15. The extrusion plate 16 is pivotally installed at the bottom of the slider 15. An arc-shaped groove is provided at the bottom end of the extrusion plate 16. Rubber pads 22 are fixedly installed on both sides of the extrusion plate 16. The extrusion plate 16 is movably installed inside the installation groove. Both ends of the first connecting pipe 6 and the second connecting pipe 7 are installed at the bottom of the inner side of the installation groove. The extrusion plate 16 is located on the top of the first connecting pipe 6 and the second connecting pipe 7 via the arc-shaped groove. Sealing rings are provided between the two ends of the connecting pipe 7 and the mounting groove. Sealing gaskets are provided between the arc-shaped groove and the first connecting pipe 6 and the second connecting pipe 7. An addition port 13 is fixedly provided at the top of one end of the second connecting pipe 7. A sealing plug is screwed to the top of the addition port 13. The water inlet tank 1 and the test chamber 2 can be connected through the first connecting pipe 6 and the second connecting pipe 7, which facilitates the quick assembly of the device. The operation is simple and convenient. The extrusion plate 16 can be raised and lowered by the handwheel 21, the screw 14 and the slider 15, so that the extrusion plate 16 can contact or separate from the first connecting pipe 6 and the second connecting pipe 7, which facilitates the fixing and disassembly of the first connecting pipe 6 and the second connecting pipe 7. The sealing rings, sealing gaskets and rubber gaskets 22 can increase the sealing between the extrusion plate 16, the first connecting pipe 6 and the second connecting pipe 7 and the mounting groove to prevent water leakage.

[0025] In this embodiment, a discharge port 11 is fixedly provided at the other end of the test chamber 2 corresponding to one side of the flow channel 8. A liquid flow meter 12 is fixedly installed on the discharge port 11. Drainage ports are provided at the bottom of one end of the flow channel 8 and the water inlet tank 1. The flow rate of seawater discharged from the flow channel 8 can be monitored through the discharge port 11 and the liquid flow meter 12 to ensure the same seawater environment inside the flow channel 8, which is convenient for conducting tests. After the test is completed, the seawater inside the water inlet tank 1 and the flow channel 8 can be discharged through the drainage port.

[0026] When using this marine biofouling test rig, place the inlet tank 1 and test chamber 2 on a flat surface. Adjust the distance between the inlet tank 1 and test chamber 2 according to the lengths of the first connecting pipe 6 and the second connecting pipe 7. Turn the handwheel 21. The handwheel 21, through the screw 14 connected to the inlet tank 1 and test chamber 2, drives the slider 15 and the extrusion plate 16 to rise. Inside the mounting slot, the extrusion plate 16 is pushed, causing it to rotate at the bottom of the slider 15 via a pivot, thereby increasing the space between the extrusion plate 16 and the bottom of the mounting slot. Install the two ends of the first connecting pipe 6 and the second connecting pipe 7 into the mounting slots inside the inlet tank 1 and test chamber 2, respectively. Turning the handwheel 21 causes the screw 14 and slider 15 to lower the extrusion plate 16, and pushes it in the opposite direction to adjust it into the mounting groove, facilitating the extrusion plate 16 to press and fix the first connecting pipe 6 and the second connecting pipe 7. Turning one end of the inlet pipe 3 upwards allows the filter frame 4 to be snapped onto the inlet tank 1. Releasing the inlet pipe 3 causes it to press against the filter frame 4 under the action of the torsion spring shaft, thus limiting its position. The test plate 20 is inserted into the placement port 17 via the placement mechanism 10, entering the flow channel 8. The vertical plate 19 slides within the placement port 17, and the limiting plate 18... The device is installed by blocking the top of the placement port 17; the other end of the inlet pipe 3 is connected to the seawater pump and pipeline, and seawater is discharged into the filter frame 4 through the inlet pipe 3. The filter frame 4 filters out larger impurities in the seawater, and the seawater enters the inlet tank 1. The seawater level in the inlet tank 1 gradually rises and simultaneously enters the first connecting pipe 6 and the second connecting pipe 7, and finally enters the flow channel 8, so that the test plate 20 is submerged in seawater. Then it is discharged through the outlet 11 and the liquid flow meter 12. The flow rate of the seawater discharged from the flow channel 8 is monitored by the liquid flow meter 12 to ensure that the interior of the flow channel 8 is in the same seawater environment; The inner wall of the first connecting pipe 6 is left untreated, while the inner wall of the second connecting pipe 7, the inner wall of the flow channel 8, and the outer wall of the test plate 20 are coated with an antifouling coating. Both the first connecting pipe 6 and the second connecting pipe 7 are transparent pipes used for comparative experiments. Marine organisms on the inner walls of the first connecting pipe 6, the second connecting pipe 7, the flow channel 8, and the outer wall of the test plate 20 are observed and recorded at certain intervals to verify the antifouling coating. Alternatively, an antifouling agent can be added to the inside of the second connecting pipe 7 through the inlet 13, and marine organisms on the inner walls of the first connecting pipe 6, the second connecting pipe 7, the flow channel 8, and the outer wall of the test plate 20 are observed and recorded periodically to verify the antifouling technology.
