Description

Technical Field

[0001] This invention belongs to the field of concrete material durability testing equipment, and particularly relates to a concrete marine experimental device with real-time monitoring and debugging functions. Background Technology

[0002] Marine environments contain corrosive media such as chloride ions, sulfate ions, and magnesium ions, and are affected by alternating factors such as tides, waves, temperature, and humidity. Concrete structures are highly susceptible to problems such as steel reinforcement corrosion, surface deterioration, cracking, and spalling in such environments. Therefore, marine exposure experiments have become an important means of studying the durability of concrete and reinforced concrete structures.

[0003] A marine exposure test apparatus is an experimental device used to place test specimens in a real marine environment. It serves to fix the test specimens, adjust their position to place them in a specific marine erosion environment, and resist the erosion of the test apparatus by the marine environment. This helps researchers accurately locate the test specimens and effectively conduct research on the durability of materials and structures under marine environmental conditions.

[0004] Existing marine exposure test setups typically consist of a base, support frame, and placement platform, used to fix and expose specimens in a marine environment. However, existing marine exposure test setups generally suffer from the following drawbacks: (1) The height or angle of the support specimen is inconvenient to adjust, and the specimen block needs to be moved manually for position correction, which is not only inefficient, but also easy to cause damage to the specimen; (2) Lacking real-time monitoring function, it is impossible to directly observe the corrosion changes of the specimens under seawater immersion. It can only be tested by periodic sampling, resulting in data discontinuity. Summary of the Invention

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0021] like Figures 1-6 As shown, the present invention provides a concrete marine experimental device with real-time monitoring and debugging functions to facilitate the adjustment of the height of the supported specimen and to achieve real-time monitoring of the experiment, thereby improving experimental efficiency and monitoring accuracy. Specifically, it includes a vertical support frame 3, which has multiple support plates 5 arranged vertically at intervals to support the specimen. Each support plate 5 is equipped with a camera 12 above it to monitor the specimen in real time. Each support plate 5 is driven to rise and fall vertically by a lifting mechanism to adjust the height of the supported specimen.

[0022] In this embodiment, the vertical support frame 3 includes four vertical support columns 20 arranged in a rectangular shape. A base plate 1 is fixed between the bottoms of the four vertical support columns 20, and a top plate 4 is fixed between the tops of the four vertical support columns 20.

[0023] In this embodiment, the support plate 5 is rectangular and located inside the four vertical support columns 20. The left end of the support plate 5 is vertically slidably engaged with the two vertical support columns 20 located on the left side, and the right end of the support plate 5 is vertically slidably engaged with the two vertical support columns 20 located on the right side. The lifting mechanism includes four vertical screw assemblies distributed around the support plate 5. Each vertical screw assembly is installed on one vertical support column 20. The four vertical screw assemblies drive the support plate 5 to move up and down along the vertical support frame 3.

[0024] In this embodiment, the support plate 5 is provided with a pair of sliding protrusions 21 distributed in front and back at both the left and right ends. Each sliding protrusion 21 is provided with a vertical screw hole 10. Each sliding protrusion 21 corresponds to the position of a vertical support column 20. The peripheral side of the vertical support column 20 is provided with a vertical groove 7 corresponding to the position of the sliding protrusion 21. The sliding protrusion 21 extends into the vertical groove 7 and slides in cooperation with the vertical groove 7.

[0025] In this embodiment, the vertical lead screw assembly is disposed in the vertical slide groove 7. The vertical lead screw assembly includes a vertical lead screw 9 that cooperates with the vertical screw hole 10. The vertical lead screw 9 is installed inside the vertical slide groove. The lower end of the vertical lead screw 9 is connected to the output shaft of the micro motor 8. The micro motor 8 drives the vertical lead screw 9 to rotate. When the vertical lead screw rotates, it drives the sliding protrusion to slide along the vertical slide groove. The sliding protrusion drives the support plate to move.

[0026] In this embodiment, the micro motor 8 is installed in the vertical slide groove 7; furthermore, the inner wall of the vertical slide groove 8 is provided with a waterproof sealing ring to prevent seawater from entering the motor cavity.

[0027] In this embodiment, the support plate 5 is provided with a carrier plate 14 for placing the test specimen. The carrier plate 14 is driven by a moving mechanism to move forward and backward to adjust the position of the test specimen. Specifically: the top surface of the support plate 5 is provided with a downwardly recessed groove 13, the shape of which is adapted to the shape of the carrying plate. The left and right sides of the support plate 5 are provided with longitudinal sliding grooves 11, which are connected to the groove 13. The carrying plate 14 slides longitudinally with the groove 13. The left and right ends of the carrying plate 14 are each provided with a horizontally arranged movable block 15, which extends into the longitudinal sliding groove 11 and slides with it. The moving mechanism includes a pair of left and right distributed longitudinal lead screw assemblies. The longitudinal lead screw assembly includes a longitudinal lead screw 17 disposed in the longitudinal sliding groove 11. The longitudinal lead screw 17 is threadedly connected to the longitudinal screw hole on the movable block 15. One end of the longitudinal lead screw 17 is connected to the drive motor 16. The drive motor 16 drives the longitudinal lead screw 17 to rotate. When the longitudinal lead screw rotates, it drives the movable block to slide along the longitudinal sliding groove, and the movable block drives the carrying plate to move.

[0028] In this embodiment, columns 2 are provided around the bottom of the base plate 1 to enhance the overall stability of the device.

[0029] In this embodiment, a photovoltaic module 19 is installed on the top of the top plate 4. The photovoltaic module 19 is electrically connected to a battery module 18 installed at the bottom of the top plate 4. The photovoltaic module converts solar energy into electrical energy, which is then stored by the battery module. Furthermore, the battery module can power a micro motor, a drive motor, and a camera. It should be noted that the photovoltaic module can be integrated into the top plate in either an embedded or fixed manner.

[0030] In this embodiment, the surface of the support plate is provided with a stainless steel wire mesh protective cover, which can be used to prevent the specimen from being washed away by the waves without affecting the tidal flow.

[0031] In this embodiment, a controller 6 is fixedly installed on the top plate 4. The controller 6 is electrically connected to the micro motor and the drive motor. The controller is equipped with a timing module for periodically starting the motor to adjust the position of the test piece. Furthermore, the photovoltaic module is connected to the power management module integrated into the controller.

[0032] In this embodiment, the topmost camera is installed inside a protective cover at the bottom of the top plate, while the other cameras are installed inside protective covers at the bottom of the support plate. The cameras maintain a fixed viewing distance from the carrying plate.

[0033] In this embodiment, the vertical support column, base plate, column and top plate are all made of 316L stainless steel, which effectively avoids seawater corrosion. The electrical equipment used is waterproof, and the camera protection level is not lower than IP68, which has waterproof and salt spray resistance.

[0034] In use, the entire device is fixed to the experimental platform or a floating hull at sea, and the controller is activated to power the system via photovoltaic modules. A concrete specimen is placed on the support plate, and a drive motor rotates a longitudinal screw, causing a moving block to propel the support plate horizontally to the support position. A micro-motor rotates a vertical screw, adjusting the height of the support plate to raise or lower the specimen. During the experiment, a camera records real-time changes on the specimen surface, allowing researchers to periodically retrieve video data to analyze the corrosion, deterioration, and deformation processes of concrete in a real marine environment. This device features a reasonable structure, simple operation, automatic adjustment, real-time monitoring, and corrosion resistance, making it suitable for long-term durability studies of concrete materials in real marine environments.

[0035] The specimens are supported by a liftable support plate, which is driven by a lifting mechanism to automatically adjust the height of the supported specimens and avoid damage caused by manual placement. Real-time monitoring via cameras allows for the assessment of the specimens' durability in a seawater environment, understanding changes in their resistance to seawater erosion and chloride ion penetration, ensuring material lifespan and engineering safety. This helps researchers accurately record the rate of corrosion changes in seawater, and long-term monitoring of the specimens' condition in the sea helps researchers determine specimen properties, whether sampling and testing are necessary, and the impact of marine environmental changes on concrete performance. This provides data support for addressing the potential impact of environmental changes on engineering structures and allows for real-time observation of specimen erosion to determine the experimental progress.

[0036] The advantages of this invention are: (1) Strong automatic adjustment: The vertical lead screw is driven by a micro motor to realize the automatic adjustment of the specimen support height, reduce manual intervention and avoid specimen damage; (2) Real-time observation: A camera is installed at the bottom of the support plate to record the corrosion of the concrete specimen in real time, thereby improving the continuity and accuracy of the experiment; (3) Energy self-sufficiency: Photovoltaic modules provide the energy source, enabling the device to operate stably at sea for a long time; (4) Corrosion-resistant and durable: The use of corrosion-resistant stainless steel and sealed electrical structure significantly improves the durability of the device in marine environments; (5) Reasonable structure: The cooperation between the loading plate and the moving block realizes the smooth movement of the specimen, which is easy to operate and safe and reliable.

Of course, a fixed connection can also be replaced by an integral structure (e.g., manufactured in one piece using a casting process) (except where it is obviously impossible to use an integral molding process).
