Description

Technical Field

[0001] This invention belongs to the field of corrosion testing methods and monitoring technology, and relates to corrosion testing and monitoring in natural environments. Specifically, it relates to a weathering resistance testing platform and method for hanging panels in a real-world scenario in an inland river basin. Background Technology

[0002] To reduce losses and prevent problems before they occur, anti-corrosion treatment of metal structures is a common practice. Among these methods, coating protection technology is the most basic and important. Therefore, evaluating the corrosion resistance of various new anti-corrosion coating materials under different service environments is of great significance.

[0003] Currently, most of the new anti-corrosion coating materials being researched are for marine engineering. However, research on the corrosion resistance of hydraulic metal structures and freshwater engineering structures in inland river basins is also of great significance, as it can provide corrosion data support for the maintenance of these structures.

[0004] Currently, the main method for studying various coating materials is through corrosion tests on coating panels. However, most of these are laboratory simulations and accelerated corrosion tests, lacking weather resistance tests under real-world service environments, especially freshwater corrosion tests in inland river basins. Furthermore, the limited number of freshwater panel corrosion tests currently conducted rely on manual handling of sample racks by operators, which is labor-intensive and lacks corresponding monitoring methods. Therefore, there is an urgent need to design a new type of weather resistance testing platform for coating panels in real-world inland river basin environments. This platform would allow for corrosion resistance studies in actual service environments, utilizing natural corrosion in different freshwater conditions to reveal the corrosion mechanisms in service environments. Simultaneously, the platform would be compared with laboratory simulation tests to explore the reliability of the simulations. Summary of the Invention

[0005] To address the aforementioned issues, the present invention aims to overcome existing shortcomings and provide a weather resistance testing platform and method for hanging plates in real-world inland river basin scenarios. This platform offers high efficiency and precision, reduces labor intensity, and meets the testing requirements of four different regions: atmospheric zone, waterline semi-immersion zone, fully immersion zone, and riverbed bottom. It provides convenience and data support for the research and development and testing of new corrosion-resistant coating materials for inland river basins.

[0006] To achieve the aforementioned technical features, the present invention aims to provide a weathering resistance testing platform for hanging panels in a real-world inland river basin scenario. This platform includes a safety fixing system, an auxiliary movement system for the hanging panel placement frame, a weathering resistance testing system, and a monitoring and control system. The weathering resistance testing system and the monitoring and control system are used to conduct real-world weathering corrosion tests on hanging panels in inland river basins. The hanging panels are positioned in four different zones from top to bottom: an atmospheric zone, a semi-submerged zone, a fully submerged zone, and the bottom of the riverbed. The corrosion behavior of the hanging panel samples in these different zones is examined. Simultaneously, data is collected using different sensors installed in the weathering resistance testing system. The monitoring and control system stores and visualizes the collected key data locally and transmits the monitoring data to a remote server via a wireless network for storage.

[0007] The safety fixing system of the test platform includes support columns, protective fences, metal mesh, metal base frame and trash rack. The metal base frame is connected to four support columns at the four corners. The protective fence is vertically arranged and connected to the metal base frame to protect the operators and prevent the hanging plate placement rack from falling accidentally. The metal mesh is laid horizontally on the metal base frame. The trash rack is vertically connected to the bottom of the metal base frame to block large-volume debris underwater and on the water surface.

[0008] The support columns, protective fences, metal grids, metal base frames, and trash racks are manufactured and connected in strict accordance with the industry standard DL / T 5358-2006. The design service life is 10-20 years according to Appendix F of this standard. The surface and connection of the test platform safety fixing system are coated with three layers: a base layer of epoxy zinc-rich primer, a middle layer of epoxy resin paint, and a top layer of polyurethane topcoat.

[0009] The auxiliary movement system for the hanging plate placement rack includes a truss and a movable pulley system. The movable pulley system includes an automatic movable pulley, a servo motor, a fixed pulley, a fixed pulley shaft, and a winch. The truss is horizontally connected to a metal base frame via a truss base. The automatic movable pulley is fixed and moves horizontally via a groove on the truss. The servo motor is horizontally mounted on a motor placement platform. The fixed pulley shaft passes through the fixed pulley and is mounted on the servo motor side of the truss. The winch is axially mounted on the servo motor shaft. Under the operation of the motion control platform, the winch is rotated by the servo motor, and the wire rope on the winch is correspondingly wound up and down. The wire rope passes through the fixed pulley and the automatic movable pulley, and the end metal hook moves the hanging plate placement rack vertically. The automatic movable pulley can move horizontally along the truss. The auxiliary movement system for the hanging plate placement rack can assist the operator in achieving directional movement of the hanging plate placement rack.

[0010] The automatic movable pulley includes a small motor, a baffle plate, a driving roller, a movable pulley shaft, a movable pulley, a driven roller, a belt drive device, and a fixing nut. The small motor drives the driving roller vertically via the belt drive device. The baffle plate is horizontally fixed on the automatic movable pulley. The movable pulley shaft passes through the movable pulley and is horizontally fixed inside the automatic movable pulley. The belt drive device is internally driven by a belt, and its protective shell is fixed by the fixing nut. The driven roller is installed opposite to the driving roller. Under the operation of the motion control platform, the automatic movable pulley drives the driving roller via the small motor and the belt drive device. The driving roller and the driven roller achieve horizontal movement through the truss slide.

[0011] The weather resistance testing system for the hanging plate includes a self-locking chute, a test hanging plate, and a hanging plate placement frame. The self-locking chute is horizontally connected to the bottom beam of the truss and the metal base frame by fixing bolts on two fixed support platforms of the chute body. The hanging plate placement frame is installed in the chute body. The two ends of the test hanging plate are vertically fixed to the crossbeams of two adjacent placement frames and vertically installed on the hanging plate placement frame. Through the motion control platform, the chute self-locking device clamps the hanging plate placement frame at a designated position, so that the hanging plate for the hanging plate test is in four different areas: atmospheric zone, waterline semi-submerged zone, fully submerged zone, and riverbed bottom.

[0012] The self-locking slide includes a slide body and a slide self-locking device, which is installed parallel to the slide body. The slide self-locking device includes a waterproof shell, a waterproof rubber pad, and an electric clamping cylinder. The electric clamping cylinder moves perpendicularly to the slide in the self-locking hole reserved in the slide body to clamp and release the hanging plate placement frame. One end of the clamping head of the electric clamping cylinder has a rubber pad with a high coefficient of friction. When the electric clamping cylinder retracts, the rubber pad with a high coefficient of friction is embedded in the waterproof rubber pad, realizing the protection of the rubber pad at the cylinder head and the waterproofing of the device.

[0013] The test platform monitoring and control system includes a monitoring and control platform and sensors installed at various locations on the platform; the monitoring and control platform is vertically installed on one side of the motor placement frame of the truss; the sensors include limit sensors installed in the truss slide and slide body, water level sensors, flow meters, temperature sensors and underwater camera modules installed on the self-locking slide and hanging plate placement frame, and photoelectric sensors and humidity sensors installed above the test platform.

[0014] The monitoring and control platform includes a power distribution box, a motion control platform, and a test monitoring platform. The motion control platform is located above the power distribution box and includes a key switch, a mode switching knob, a touch screen, and an emergency stop button. It is also equipped with a motion control module responsible for controlling the movement of the entire platform. The main body of the test monitoring platform is the monitoring screen. Data collected by the sensors is displayed on the monitoring screen through a data acquisition and processing module and a data visualization module. The collected data is stored locally on the control platform through a data storage module and simultaneously transmitted to a remote server via a wireless network through a data transmission module.

[0015] An operational method for a weather resistance testing platform for hanging panels in a real-world inland river basin scenario includes the following steps: Step 1: The operator applies the paint whose corrosion resistance needs to be verified to the test hanging plate, turns on the key switch on the motion control platform, selects automatic or manual mode using the mode switching knob. In automatic mode, the plate will automatically move at the set distance, while in manual mode, the distance is manually controlled. The steel wire rope on the automatic pulley is lowered, the metal hook is hung on the hanging plate placement frame lifting lug, the hanging plate placement frame is lifted, and the test hanging plate is installed on the hanging plate placement frame. Step 2: The operator uses the water level and video information on the test monitoring platform to select a suitable weather resistance test area for the hanging plate on the motion control platform. The hanging plate placement frame will be lowered into the self-locking slide. Several electric clamping cylinders will selectively clamp the hanging plate placement frame according to the set position to fix one hanging plate placement frame. Step 3: The operator repeats the above steps to fix the hanging plate placement rack for the next time until the pre-set number of hanging plates for multi-area testing is reached or the hanging plate placement rack reaches the platform design limit. Step 4: After ensuring that all the above steps are qualified, the operator shuts down the motion control platform, checks the integrity of the sensor data on the test monitoring platform, and then leaves the entire platform. Step 5: The operator enters the test platform again according to the set test cycle, repeats Step 4, and at the same time manually uses the storage device to copy the monitoring data locally on the test monitoring platform, and provides dual data protection with the data stored on the remote server through the wireless network; Step 6: When the operator finds that several test panels have achieved the predetermined test effect, remove the batch of test panels, obtain the last corrosion data of this test, and save it. Step 7: Repeat Step 5 and Step 6. Once all test panels have been removed, the operator should shut down all equipment and terminate the entire test.

[0016] The present invention has the following beneficial effects: 1. This invention reduces the labor intensity of operators through the auxiliary movement system of the hanging plate placement frame. At the same time, the limit sensors installed in the truss slide and slide body can provide the specific position data of the automatic moving pulley and hanging plate placement frame after being squeezed. The self-locking device can selectively extend the electric clamping cylinder to clamp the device, providing more accurate and intelligent test positioning.

[0017] 2. This invention utilizes a weathering resistance testing system for hanging plates, based on data from a water level sensor, to ensure the hanging plates are placed in four different zones: the atmospheric zone, the semi-submerged zone, the fully submerged zone, and the riverbed bottom. Simultaneously, a flow meter, photoelectric sensor, temperature and humidity sensor, and underwater camera module are installed to verify the multi-factor coupled corrosion mechanism of materials used in inland waterways.

[0018] 3. The present invention uses a test platform monitoring and control system to facilitate operators in controlling the movement and positioning of the hanging plate placement rack. At the same time, it can monitor key environmental factors of the entire hanging plate weather resistance test, save environmental data locally and transmit it remotely to a remote server via wireless network for storage, ensuring the integrity and security of data on multiple environmental factors.

In section 8.2.1), the protection of the cylindrical head rubber pad and the waterproofing of the device are achieved.

6. The operating method of the weathering resistance testing platform for hanging panels in a real-world inland river basin scenario as described in any one of claims 1-5, characterized in that, Includes the following steps: Step 1: The operator applies the paint required to verify corrosion resistance to the test mounting plate (14), and turns on the key switch on the motion control platform (13.2). 13.2.1) Select automatic or manual mode by using the mode switching knob (13.2.2). In automatic mode, the distance will be set automatically, while in manual mode, the distance will be controlled manually. Lower the wire rope on the automatic pulley (3), hang the metal hook on the hanging plate placement frame lifting lug (15.1), lift the hanging plate placement frame (15), and install the test hanging plate (14) on the hanging plate placement frame (15). Step 2: The operator selects a suitable weather resistance test area for the hanging plate on the motion control platform (13.2) by using the water level and video information on the test monitoring platform (13.3). The hanging plate placement frame (15) will be lowered into the self-locking slide (8). Several electric clamping cylinders (8.2.2) selectively clamp the hanging plate placement frame (15) according to the set position to achieve the fixation of one hanging plate placement frame (15). Step 3: The operator repeats the above steps to fix the hanging plate placement rack (15) for the next time until the number of pre-set multi-area test hanging plates (14) is reached or the hanging plate placement rack (15) reaches the upper limit of the platform design. Step 4: After ensuring that all the above steps are qualified, the operator shuts down the motion control platform (13.2), checks the integrity of the sensor data on the test monitoring platform (13.3), and then leaves the entire platform. Step 5: The operator enters the test platform again according to the set test cycle, repeats Step 4, and at the same time manually uses the storage device to copy the local monitoring data of the test monitoring platform (13.3) and the data stored on the remote server through the wireless network to ensure dual data protection; Step 6: When the operator finds that several test plates (14) have achieved the predetermined test effect, take out the batch of test plates (14), obtain the last corrosion data of this test and save it; Step 7: Repeat Step 5 and Step 6. When all test plates (14) have been removed, the operator should turn off all equipment and terminate the entire test.
