Description

Technical Field

[0001] This invention relates to the field of slope protection performance testing technology, and in particular to a device for testing the wave-damping and erosion resistance performance of plant-based ecological concrete. Background Technology

[0002] Vegetated ecological concrete is a composite structure with porous concrete as its framework and plants planted inside. It is widely used in water conservancy projects, municipal engineering projects and ecological restoration, among which slope protection is a common application scenario for vegetated ecological concrete.

[0003] To test the erosion resistance of vegetation-based ecological concrete slope protection, existing technologies typically use wave simulation devices to model the slope protection against frontal erosion. However, this approach has the following drawbacks:

[0004] 1. In practical applications, the slope protection is not directly facing the impact direction of the waves; there is usually a certain angle between them. Existing technology cannot simulate the lateral erosion of the slope protection by waves.

[0005] 2. The slope protection model can have its tilt angle adjusted by a tilt adjustment mechanism. However, the tilt adjustment mechanism is usually located at the bottom of the slope protection model, which will create resistance to the waves and thus affect the scouring effect of the waves on the slope protection model, resulting in unreliable test results. Similarly, if a tilt adjustment mechanism is set to adjust the angle between the slope protection model and the direction of the wave impact, it will also affect the scouring effect of the waves on the slope protection model.

[0006] 3. The wave-damping performance of the slope protection model cannot be tested.

[0007] Therefore, how to provide a device for testing the erosion resistance and wave dissipation performance of slope protection is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0008] The purpose of this invention is to provide a testing device for the wave-damping and erosion resistance performance of vegetation-type ecological concrete, so as to solve the problems existing in the prior art.

[0009] To achieve the above objectives, the present invention provides a testing device for the wave-damping and erosion resistance performance of vegetation-type ecological concrete, comprising:

[0026] A drive mechanism, connected to the limiting plate, is used to drive the limiting plate and the dynamic friction ring to rotate;

[0027] An elastic lifting mechanism, connected to the drive mechanism, has an elastic tendency to push the limiting member toward the lower surface of the fixed friction ring.

[0028] Furthermore, the rotary table has a square groove corresponding to the model frame, the first connecting ear is disposed in the square groove, and the model frame is connected to the upper edge of the square groove through a sealing rubber connector, the sealing rubber connector being close to the bottom of the model frame.

[0029] Furthermore, the drive mechanism includes:

[0034] A connecting plate is provided on which the first drive motor and the first bearing housing are mounted;

[0035] The first spring assembly has one end connected to the lower surface of the connecting plate and the other end disposed on the bottom surface of the lower chamber.

[0036] Furthermore, the synchronous rotation mechanism includes:

[0037] A rotating disk is arranged near the top surface of the test chamber and concentrically with the rotating table.

[0038] A mounting plate is disposed on the lower surface of the rotating disk, and the adjusting cylinder is hinged to the mounting plate via a third connecting lug;

[0041] The second engaging gear is disposed on the second rotating shaft;

[0042] A second drive motor is mounted on the bracket, and its output end is provided with a second drive gear, which meshes with a second engagement gear.

[0043] Furthermore, it also includes:

[0044] Multiple wave height meters are respectively installed on the partition and located on the left and right sides of the rotating platform, used to measure the wave height before and after the wave flow erodes the slope protection model.

[0045] Furthermore, it also includes:

[0046] A wave-damping filter is inclinedly installed in the upper chamber of the test chamber, with its bottom rotatably connected to the partition and its top extending toward the top surface of the test chamber.

[0047] The top plate is fixedly connected to the top of the wave-damping filter screen, and multiple second spring assemblies are provided between the top plate and the top surface of the test chamber.

[0048] Furthermore, the wave-damping filter screen is provided in multiple sets, with the multiple sets of wave-damping filter screens spaced apart. The partition plate is recessed downward to form a filter pool corresponding to the multiple sets of wave-damping filter screens. The filter pool is provided with a support column, and the multiple sets of wave-damping filter screens can be rotatably mounted on the support column or rotatably mounted on the partition plate.

[0049] The present invention discloses the following technical effects:

[0050] 1. The tilt adjustment mechanism is located on the top surface of the test chamber. It drives the slope protection model to rotate by adjusting the cylinder. The setting position and working process of the tilt adjustment mechanism do not affect the wave flow scouring the slope protection model, which helps to improve the authenticity of the scouring effect and improve the detection accuracy.

[0051] 2. The angle adjustment mechanism is located in the lower chamber of the test chamber. The bottom of the slope protection model is hinged to the rotary table. When the rotary table rotates, the synchronous rotation mechanism drives the adjustment cylinder to rotate coaxially, realizing the adjustment of the angle between the slope protection model and the wave flow and realizing the coupling of the angle adjustment mechanism and the tilt adjustment mechanism. The rotary table is flush with the partition, so the rotary table will not affect the wave flow scouring the model.

[0052] 3. This application adopts a "dynamic sealing" structure. The rotating platform is set inside the dynamic friction ring, and the dynamic friction ring and the static friction ring are rotatably connected and their connection surfaces are sealed with sealing grease. A limiting plate is set at the bottom of the dynamic friction ring, and the limiting plate is rotatably connected to the bottom surface of the static friction ring through a limiting element and its connection surface is sealed with sealing grease. Under the synergistic effect of the above two sets of sealing structures, water flow can be prevented from entering the angle adjustment mechanism. In addition, based on the elastic force of the first spring assembly, the limiting plate can always be tightly fitted to the lower surface of the static friction ring, which can further improve the sealing performance.

[0053] 4. Wave height meters are placed on the left and right sides of the slope protection model to detect the wave height before and after the wave flow scours the slope protection model, thereby obtaining the energy change before and after scour and evaluating the wave dissipation performance of the slope protection model.

[0054] 5. This application integrates filtration and wave-damping functions. Specifically, the filter screen itself acts as a filter, trapping impurities in the wave flow after the slope protection model is eroded, and then using the amount of impurities to assess the erosion resistance and corrosion resistance of the slope protection model. When the wave flow impacts the filter screen, energy is transferred from bottom to top along the filter screen. During the transfer process, some energy can be reduced. When the energy is transferred to the top of the filter screen, it can be released through the elastic deformation and vibration of the second spring assembly, thereby realizing the wave-damping function. Wave flow wave-damping helps to avoid energy reflection, which would lead to inaccurate wave height measurement data. Attached Figure Description

[0062] Among the existing technologies retrieved:

[0064] Slope simulation device: An inclined soil and rock layer bearing device, which is divided into multiple areas by partitions. Each area contains a slope soil and rock layer, and a vegetation layer is arranged on the soil and rock layer.

[0065] Rainfall simulation device: includes a height-adjustable support and a rain plate. The lower surface of the rain plate is arranged with serpentine connecting pipes. There are multiple water outlets at the bottom of the pipes, which can adjust the rainfall intensity and flow rate.

[0066] Slope adjustment device: including support plate, angle adjustable bracket, slide rail and locking buckle, used to adjust the slope of the slope simulation device.

[0067] Effluent collection device: including mud and water collection tank, collection trough and collection container, used to collect surface runoff, erosion material and mud and water that seep into the soil and rock layer of the slope.

[0068] This device can simulate slope erosion processes under different slope gradients and rainfall intensities, collect and analyze eroded materials, and study the impact of vegetation layer on slope stability. It features a simple structure, low cost, and freely adjustable slope, enabling comprehensive analysis of slope rainfall infiltration patterns and providing data for numerical simulation and analysis. It is suitable for the research and application of ecological slope protection technologies and provides guidance for slope hydroseeding engineering construction and research.

[0069] Patent 201620538174.8 discloses a testing device for simulating anti-slip and anti-rainwater erosion of concrete frame block slope protection, including:

[0070] The simulated slope adjustment mechanism includes a first support, a first rectangular frame, a slope simulation support plate, and a slope adjustment power drive mechanism. The tilt angle of the slope simulation support plate is controlled by adjusting a hydraulic cylinder.

[0071] The simulated rain mechanism includes a second support frame, a water pump, a water tank, rigid water pipes, solenoid valves, and sprinklers. The water tank is divided into multiple chambers, and the water supply to different chambers is controlled by solenoid valves to simulate rainfall in different areas.

[0072] The testing process is as follows:

[0073] Anti-slip stability test: Start the adjustable hydraulic cylinder and gradually increase the inclination angle of the slope simulation support plate, and record the slope ratio when the concrete grid block or soil layer begins to slide.

[0074] Rainwater erosion resistance test: After adjusting the tilt angle of the simulated slope support plate, simulated rainfall erosion was applied to the soil and vegetation within the concrete grid blocks using a water pump and nozzles. The erosion time and the vegetation's erosion resistance were recorded. A horizontal scale and a flexible scale were used to accurately measure the slope ratio; a telescopic waterproof cylinder protected the adjusting hydraulic cylinder; and reinforcing ribs improved the load-bearing capacity of the simulated slope support plate.

[0075] This device can simulate the anti-sliding stability and rainwater erosion resistance of concrete grid block slopes under different slope conditions, providing data support for civil engineering construction.

[0084] In this embodiment, the slope protection model 3 includes:

[0085] The model frame 301 defines multiple mounting slots 302, and the mounting slots 302 are filled with ecological concrete samples.

[0086] The first hinge shaft 304 is located at the bottom of the model frame 301, and the first hinge shaft 304 is hinged to the experimental box through the first connecting lug 303.

[0087] The second hinge shaft 305 is disposed on the top of the model frame 301 via the second connecting ear 306, and there is a gap between the second hinge shaft 305 and the top of the model frame 301.

[0088] The tilt adjustment mechanism is an adjustment cylinder 4, which is located on the top surface of the test chamber 1, and its telescopic rod is hinged to the second hinge shaft 305.

[0089] In this embodiment, it also includes:

[0090] A partition 5 is horizontally set inside the test chamber 1, dividing the test chamber 1 into an upper chamber 103 and a lower chamber 104. The inlet 101 and the outlet 102 are both connected to the upper chamber 103.

[0091] An angle adjustment mechanism is provided in the lower chamber 104. The angle adjustment mechanism has a rotating platform 6 and is used to drive the rotating platform 6 to rotate. The rotating platform 6 is rotatably and sealed in the partition 5. The upper surface of the rotating platform 6 is flush with the partition 5. The first connecting ear 303 is provided on the rotating platform 6.

[0092] The synchronous rotation mechanism is located on the top surface of the test chamber 1 and connected to the adjusting cylinder 4; when the included angle adjusting mechanism drives the rotating table 6 to rotate, the synchronous rotation mechanism drives the adjusting cylinder 4 to rotate coaxially.

[0093] In this embodiment, the included angle adjustment mechanism includes:

[0094] The fixed friction ring 7 and the partition plate 5 have mounting holes that extend through the upper and lower surfaces. The fixed friction ring 7 is adapted to the shape of the mounting holes and is set in the mounting holes.

[0095] A moving friction ring 8 and a rotating platform 6 are embedded on the inner side of the moving friction ring 8. The outer side of the moving friction ring 8 is in contact with the inner side of the fixed friction ring 7. A limiting plate 9 is provided at the bottom of the moving friction ring 8. The limiting plate 9 extends outward to form a limiting member 901. The upper surface of the limiting member 901 is in contact with the lower surface of the fixed friction ring 7.

[0098] In this embodiment, the rotary table 6 has a square groove 601 corresponding to the model frame 301. The first connecting ear 303 is disposed in the square groove 601. The model frame 301 is connected to the upper edge of the square groove 601 through a sealing rubber connector 10, which is located near the bottom of the model frame 301. The square groove 601 allows the bottom of the slope protection model 3 to be flush with the partition 5, which can avoid the first hinge shaft 304 from generating resistance to the wave flow and simulate the actual wave flow erosion of the slope protection to the greatest extent.

[0099] In this embodiment, the driving mechanism includes:

[0100] The first rotating shaft 11 is connected to the limiting plate 9 at its upper end and is rotatably mounted on the first bearing seat 12 at its lower end.

[0103] The first drive motor 14 has a first drive gear 15 at its output end, and the first drive gear 15 meshes with the first engagement gear 13.

[0104] The flexible lifting mechanism includes:

[0105] The connecting plate 16, the first drive motor 14 and the first bearing seat 12 are mounted on the connecting plate 16;

[0106] The first spring assembly 17 is connected at one end to the lower surface of the connecting plate 16, and at the other end to the bottom surface of the lower chamber 104.

[0107] In this embodiment, the synchronous rotation mechanism includes:

[0108] The rotating disk 18 is arranged near the top surface of the test chamber 1 and concentrically with the rotating table 6;

[0109] Mounting plate 19 is located on the lower surface of rotating disk 18, and adjusting cylinder 4 is hinged to mounting plate 19 via third connecting lug 20;

[0110] Support 21 is installed on the top surface of test chamber 1;

[0111] The second rotating shaft 22 has its lower end penetrating through the top surface of the test chamber 1 and connected to the rotating disk 18, and its upper end is rotatably mounted on the second bearing seat 23, which is installed on the bracket 21.

[0112] The second engaging gear 24 is disposed on the second rotating shaft 22;

[0113] The second drive motor 25 is mounted on the bracket 21, and its output end is provided with a second drive gear 26, which meshes with the second engagement gear 24.

[0114] In this embodiment, it also includes:

[0115] Multiple wave height meters 27 are respectively set on the partition plate 5 and located on the left and right sides of the rotating platform 6, and are used to measure the wave height before the wave flow scours the slope protection model 3 and the wave height after the wave flow scours the slope protection model 3.

[0116] In this embodiment, it also includes:

[0117] The wave-damping filter 28 is inclinedly installed in the upper chamber 103 of the test chamber 1, with its bottom rotatably connected to the partition 5 and its top extending toward the top surface of the test chamber 1.

[0118] The top of the top plate 29 and the top of the wave-damping filter 28 are fixedly connected to the top plate 29. Multiple second spring assemblies 30 are provided between the top plate 29 and the top surface of the test chamber 1.

[0119] In this embodiment, two sets of wave-damping filter screens 28 are provided, with the two sets of wave-damping filter screens 28 spaced apart. The wave-damping filter screen 28 closer to the outlet 102 has a smaller aperture. The partition 5 is recessed downward to form a filter pool 31 corresponding to multiple sets of wave-damping filter screens 28. A support column 32 is provided in the filter pool 31. The wave-damping filter screen 28 closer to the outlet 102 is rotatably mounted on the partition 5, and the wave-damping filter screen 28 farther from the outlet 102 is rotatably mounted on the support column 32. Due to the vibration of the filter screen generated by the impact force of the wave flow, impurities can fall naturally into the filter pool 31 and will not accumulate on the surface of the filter screen.

[0120] The specific work process is as follows:

[0121] The wave-simulating pump 2 operates intermittently, outputting wave-like water flow towards the outlet 102. This flow travels along the upper surface of the baffle 5. When the wave-like water flow passes through multiple wave height meters 27 on the left side of the rotating platform 6, these meters record the wave height data before the water flow scours the slope protection model 3. When the wave-like water flow passes through multiple wave height meters 27 on the right side of the rotating platform 6, these meters record the wave height data after the water flow scours the slope protection model 3. The wave-dissipating performance of the slope protection model 3 can be calculated using the wave height data obtained from both sides. The specific calculation method is existing technology and will not be elaborated here. The wave-like water flow continues to flow after scourning the slope protection model 3. When the wave-like water flow impacts the filter screen, the impurities generated by the scour are trapped by the filter screen. The energy of the wave-like water flow is transferred to the filter screen and then upwards along the inclined direction of the filter screen. When it reaches the top of the filter screen, it is completely released by the vibration and elastic deformation of the second spring assembly 30. Therefore, no water flow reflection wave is generated on the right side of the rotating platform 6.

[0122] When it is necessary to adjust the tilt angle of the slope protection model 3, the adjusting cylinder 4 is activated, and the slope protection model 3 is rotated along the axis of the first hinge shaft 304 via the telescopic rod.

[0123] When it is necessary to adjust the angle between the slope protection model 3 and the wave flow, the first drive motor 14 and the second drive motor 25 are started simultaneously. The first drive motor 14 drives the limit plate 9 and the rotating table 6 to rotate together, and the second drive motor 25 drives the rotating disk 18, the mounting plate 19 and the adjusting cylinder 4 to rotate together. Since the rotating table 6 and the rotating disk 18 are arranged coaxially, the relative position of the adjusting cylinder 4 and the slope protection model 3 remains unchanged. The two rotate synchronously to realize the adjustment of the angle between the slope protection model 3 and the wave flow.

[0124] Explanation of the sealing performance of the angle adjustment mechanism:

[0125] A rotating platform 6 is disposed inside the dynamic friction ring 8, which is rotatably connected to the static friction ring and the connection surface is sealed with sealing grease. A limiting plate 9 is provided at the bottom of the dynamic friction ring 8, which is rotatably connected to the bottom surface of the static friction ring via a limiting member 901 and the connection surface is sealed with sealing grease. Under the synergistic effect of the above two sets of sealing structures, water flow can be prevented from entering the angle adjustment mechanism. In addition, based on the elastic force of the first spring assembly 17, the limiting plate 9 can always be tightly fitted to the lower surface of the static friction ring, which can further improve the sealing performance.
