Description

Technical Field

[0001] This invention relates to the field of friction coefficient measuring device technology, specifically a friction coefficient testing device for the anti-slip coating of aquaculture vessel deck. Background Technology

[0002] The deck of an aquaculture vessel is the core open-air area used for aquaculture operations and to ensure the vessel's operation, serving a dual purpose of production and functional support. Its surface is typically made of non-slip, corrosion-resistant materials. The layout includes areas for operating aquaculture equipment (such as cage lifting and feeding device control), fry / adult fish transfer areas, material storage areas, and crew access routes. Some decks are also equipped with lifting equipment, pipeline interfaces, and safety protection facilities. It can directly cooperate with the underwater aquaculture system to complete key processes such as fry release, feed delivery, and fish harvesting, while also meeting the stability and safety requirements of the vessel during navigation.

[0003] To ensure the safety of personnel and equipment and prevent accidents such as slipping, falling, or equipment slippage caused by slippery decks, the friction coefficient of the anti-slip coating on aquaculture vessels needs to be tested regularly to ensure that the anti-slip performance of the coating meets the safety standards for ship operation and navigation. Current technology generally uses portable sliding friction meters for measurement. However, this method requires manual cleaning of the deck before measurement, which is inefficient and cannot simulate the environment of residual seawater on the deck during actual operations.

The bottom of the gas delivery pipe is connected to the diversion box through a telescopic tube. An adjusting plate is fixedly installed on the side wall of the diversion box near the partition, and a ball bearing is embedded in the top of the adjusting plate. Cams are fixedly fitted on both ends of the rotating shaft, and the two cams respectively contact the ball bearings on the top of the two adjusting plates.

This allows for zoned testing under two conditions during the same test: deck dryness and seawater adhesion, eliminating the need for repeated adjustments to the device or test position. Simultaneously, through the synergistic action of pressure sensor one, pressure sensor two, and the elastic connecting component in the friction coefficient testing mechanism, the horizontal thrust and vertical pressure on the test block can be automatically detected. The static and dynamic friction coefficients are automatically calculated via the control panel software, further improving testing efficiency and data accuracy. This provides efficient and reliable technical support for testing the anti-slip coating performance of aquaculture vessel decks, ensuring the safety of personnel and equipment.

[0028] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Please see Figures 1-6In this embodiment of the invention, a friction coefficient testing device for the anti-slip coating of an aquaculture vessel deck includes a testing platform 1, a friction coefficient testing mechanism disposed below the testing platform 1, a driving mechanism disposed on the testing platform 1 for driving the friction coefficient testing mechanism to move horizontally, a partition assembly disposed in the middle of the lower surface of the testing platform 1, and a water spray assembly. Two friction coefficient testing mechanisms are provided and distributed on both sides of the partition assembly. The water spray assembly is disposed on one side of the partition assembly. A flow divider box 26 is provided on both sides of the partition assembly, and multiple high-pressure nozzles 27 are installed on the flow divider box 26, with the high-pressure nozzles 27 inclined downwards. During the movement, high-pressure gas is injected into the diversion box 26, and the high-pressure gas is sprayed out through the high-pressure nozzle 27 to clean the deck area below the test platform 1, preventing excessive dust on the deck from affecting the test accuracy. By setting up two friction coefficient testing mechanisms, the friction coefficient of the clamping plate area on both sides of the partition component can be tested. Before the test, seawater is sprayed onto one side of the partition 22 by the water spray component, so that seawater adheres to the deck surface, so as to realize the friction coefficient measurement when there is seawater on the deck. The other side of the partition 22 is in a dry state, so as to realize the friction coefficient measurement under dry deck conditions. The deck friction coefficient can be measured under both conditions.

[0030] Among them, see Figure 5 and Figure 6 The partition assembly includes partitions 22, rotating shafts 23, drive wheels 24, and flexible water-resistant belts 25. Two partitions 22, rotating shafts 23, and drive wheels 24 are provided. Two partitions 22 are fixedly connected to the lower surface of the test platform 1, with a gap between them. Two rotating shafts 23 are parallel to each other and pass through both partitions 22, rotatably connected to the partitions 22. The two rotating shafts 23 are distributed on both sides inside the gap. Two drive wheels 24 are respectively fixedly mounted on the two rotating shafts 23. The flexible water-resistant belt 25 is mounted on the two drive wheels 24. The bottom wall of the flexible water-resistant belt 25... The height is lower than the bottom wall of the bulkhead 22. During the test, the bottom wall of the flexible water-proof belt 25 is in contact with the deck. As the test platform 1 moves horizontally, the flexible water-proof belt 25 drives the transmission wheel 24 to rotate. Through the height of the flexible water-proof belt 25 and the deck, combined with the blocking effect of the bulkhead 22, the two friction coefficient test mechanisms can be effectively separated, so that the water sprayed by the water spray component cannot flow to the other side of the bulkhead 22, thus ensuring the accuracy of the zone test. Compared with only setting the bulkhead 22 for blocking, the water-proof effect is better, and the direct friction between the bulkhead 22 and the deck is effectively avoided, thus preventing wear.

[0031] Among them, see Figure 1 and 10The water spray assembly includes a water storage tank 18 mounted on the upper surface of the test platform 1, a water spray head 19 mounted on the lower surface of the test platform 1, a water pump 20 mounted on the top wall of the water spray head 19, and a water supply pipe 21. The top end of the water supply pipe 21 is connected to the water storage tank 18, the bottom end of the water supply pipe 21 is connected to the inlet end of the water pump 20, and the outlet end of the water pump 20 is connected to the water spray head 19. The bottom of the water spray head 19 has multiple spray holes. In use, seawater is put into the water storage tank 18. When the water pump 20 is turned on, the seawater in the water storage tank 18 is input into the water spray head 19 through the water supply pipe 21 and the water pump 20, and then sprayed out through the multiple spray holes at the bottom of the water spray head 19. The sprayed seawater covers the test area of ​​one of the friction coefficient testing mechanisms.

[0032] Among them, see Figure 1 and Figure 3 The driving mechanism includes a screw 13, a motor 14, and a slide block 2. A groove 101 is provided on the test platform 1, and the slide block 2 is slidably installed within the groove 101. The screw 13 passes through the slide block 2 and is threadedly connected to it. The motor 14 is fixedly installed on the test platform 1, and its output end is fixedly connected to one end of the screw 13. A cylinder 3 is fixedly installed on the upper surface of the slide block 2, and its output end passes through the slide block 2 and is fixedly connected to a lifting plate 15. The motor 14 drives the screw 13 to rotate, causing the slide block 2 to move horizontally, thereby causing the lifting plate 15 to move horizontally. When the output end of the cylinder 13 extends or retracts, it causes the lifting plate 15 to rise or fall, thus enabling the friction coefficient testing mechanism to move horizontally and rise or fall.

[0033] Among them, see Figure 3 and Figure 4The friction coefficient testing mechanism includes an elastic connection assembly, a transverse guide rail 7, a slide block 8 slidably installed inside the transverse guide rail 7, a spring 9 and a pressure sensor 10 disposed inside the transverse guide rail 7, a pressure sensor 11 fixedly installed on the lower surface of the slide block 8, and a test block 12 fixedly installed on the detection end of the pressure sensor 11. The transverse guide rail 7 is elastically connected to the lifting plate 15 through the elastic connection assembly. The pressure sensor 10 is fixedly installed on the inner side wall of the transverse guide rail 7. The slide block 8 is elastically connected to the detection end of the pressure sensor 10 through the spring 9. The elastic connection assembly includes a connecting cylinder 4, a connecting column 5, and a spring 9. 6. The top end of the connecting column 5 is fixedly connected to the lifting plate 15, and the bottom end of the connecting cylinder 4 is fixedly connected to the upper surface of the transverse guide rail 7. The bottom end of the connecting column 5 extends into the connecting cylinder 4, and the connecting column 5 and the connecting cylinder 4 are slidably engaged. The connecting column 5 is elastically connected to the bottom wall of the connecting cylinder 4 by spring 6. The inner wall of the connecting cylinder 4 is provided with a limit protrusion, so that the connecting cylinder 4 can only move up and down relative to the connecting column 5, and the connecting cylinder 4 cannot rotate. During the test, the lifting plate 15 is first driven to descend by cylinder 3. When the lifting plate 15 descends, the transverse guide rail 7 is driven to move downward through the elastic connecting assembly. When the transverse guide rail 7 moves downward, it is driven by the slide block 8 and the pressure sensor 1. 1. The test block 12 moves downward, pressing it onto the deck. Pressure sensor 11 detects the pressure exerted by the test block 12 on the deck. Then, the continuing descent of the lifting plate 15 moves the connecting column 5 downward, compressing the spring 6. The greater the compression of spring 6, the greater the pressure exerted by the test block 12 on the deck. When the pressure reaches the required level, the driving mechanism moves the lifting plate 15 horizontally. During this horizontal movement, the elastic connecting assembly moves the transverse guide rail 7 horizontally, gradually compressing the spring 9. Pressure sensor 10 detects the pressure exerted on the slide 8. The thrust value is measured by pressure sensor 11 acting on test block 12, which measures the horizontal thrust and vertical pressure acting on the deck. The software on control panel 38 automatically calculates the deck's coefficient of friction. When calculating the static friction coefficient, pressure sensor 11 detects the pressure N exerted by test block 12 on the deck when it is pressed against it. As lifting plate 15 descends, connecting column 5 moves downward to compress spring 6. At the moment test block 12 is about to slide, pressure sensor 10 detects the maximum thrust value of slide block 8; this thrust value is the static friction force f. s According to the formula μ s =f s / N, the software within the control panel 38 automatically calculates the static friction coefficient by acquiring real-time data from pressure sensor 10 and pressure sensor 11. When calculating the dynamic friction coefficient, after test block 12 begins to slide, it maintains a uniform sliding speed. Pressure sensor 10 detects the stable thrust value experienced by slide block 8 at this time; this is the dynamic friction force f. k The pressure value detected by pressure sensor 211 is still a positive pressure N, according to the formula μ k =f k / N, the software in the control panel 38 automatically calculates the coefficient of dynamic friction by acquiring real-time data from pressure sensor 10 and pressure sensor 21 during the uniform sliding phase of test block 12.

[0034] In this embodiment, preferably, cylinders 16 are fixedly installed on both sides of the upper surface of the test platform 1, and electromagnets 17 are fixedly installed at the output ends of the two cylinders 16. The electromagnets 17 are located below the test platform 1. During the test, in order to avoid the test platform 1 moving and affecting the test accuracy, the output ends of the cylinders 16 are extended so that the electromagnets 17 come into contact with the deck. Then the electromagnets 17 are turned on so that they are magnetically attracted to the deck, thereby fixing the test platform 1 and preventing it from moving.

[0035] In this embodiment, preferably, a push handle 37 is fixedly installed on one side of the top of the test platform 1, and a control panel 38 is installed on the top of the push handle 37. Multiple casters 102 are provided at the bottom of the test platform 1, enabling the test platform 1 to move on the deck. The push handle 37 can be used to push the test platform 1 to move the device to different areas for testing. The control panel 38 can be used to control the device to work and can display the measured friction coefficient. The control panel 38 has a control module that can be used to control the operation of the motor 14, cylinder 3, cylinder 16, water pump 20, etc., to realize the operation of the friction coefficient testing mechanism and the function of seawater spraying. At the same time, the control panel 38 also has a display module that can display the pressure values ​​detected by pressure sensor 10 and pressure sensor 11 in real time, as well as the automatically calculated static friction coefficient and dynamic friction coefficient. In addition, the control panel 38 also has a storage module that can store the measurement data for easy viewing and analysis later. The above functions are all implemented in the prior art.

[0036] Please see Figures 7-9 In this embodiment of the invention, the upper surface of the test platform 1 is provided with a gas storage tank 36. The gas outlet of the gas storage tank 36 is connected to two gas supply pipes 28 through a solenoid valve. The gas supply pipes 28 are connected to the distribution box 26. Gas can be input into the gas supply pipes 28 through the gas storage tank 36. The gas is sprayed out from the high-pressure nozzle 27 through the distribution box 26, thereby cleaning the deck.

[0037] In this embodiment, preferably, longitudinal guide rails 30 are fixedly installed on both sides of the partition 22, and a slide block 31 is slidably installed inside the longitudinal guide rail 30. The slide block 31 is fixedly connected to the diversion box 26, and the bottom wall of the slide block 31 is elastically connected to the bottom wall of the longitudinal guide rail 30 through a spring 32. The bottom of the gas delivery pipe 28 is connected to the diversion box 26 through a telescopic pipe 29. An adjusting plate 34 is fixedly installed on the side wall of the diversion box 26 near the partition 22. A ball bearing 35 is embedded in the top of the adjusting plate 34. Cams 33 are fixedly fitted on both ends of the rotating shaft 23, and the two cams 33 are respectively connected to the ball bearings 35 on the top of the two adjusting plates 34. Five phases in contact; during the movement of the test platform 1, the flexible water-proof belt 25 drives the rotating shaft 23 to rotate through the transmission wheel 24. When the rotating shaft 23 rotates, it drives the two cams 33 to rotate. With the elastic force of the spring 32, the cams 33 rotate and drive the diversion box 26 to reciprocate up and down through the adjustment plate 34, which in turn drives the high-pressure nozzle 27 to reciprocate up and down. This allows the high-pressure nozzle 27 to automatically adjust the spray position, thereby improving the cleaning effect on the deck. The power of the rotation of the flexible water-proof belt 25 can be used to drive the high-pressure nozzle 27 to reciprocate up and down, without the need for other electrical drive structures. The synchronization is good and the production and maintenance costs of the device are reduced.
