[0013] The emergency power anchor dynamic water penetration test method is operated using the emergency power anchor dynamic water penetration test system, including the following steps: S1. Set up soil trough: Use fine loess with a median particle size of 0.02 mm to simulate the breached riverbed soil. Place fine loess in the soil trough at the bottom of the glass water tank and compact, fill, flatten, and water it for testing; S2. Set up the video acquisition module and auxiliary lighting module: install the top-view bracket, front-view bracket and side-view bracket above, on the side and inside the glass water tank test area, respectively; install a top-view high-speed camera on the top-view bracket, a front-view high-speed camera on the front-view bracket, and a side-view waterproof high-speed camera on the side-view bracket.

Adjust the viewing angle and prepare for shooting; install an LED light strip around the soil trough at the bottom of the glass water tank, and install a lighting lamp on the top edge of the glass water tank to ensure sufficient light during the test period; S3. Debug the simulated breach water flow boundary: start the water pump, use the flow control solenoid valve to slowly increase the flow, adjust the water depth through the stainless steel shutter tail gate until the water depth and flow rate are controlled to meet the test conditions, record the flow, water depth, flow rate, water temperature and other parameters, and adjust the auxiliary lighting module to meet the visual transparency of the water body; S4. Debug the power anchor launch module: first level the beam using the bubble level on the beam, rotate the internal threaded sleeve to adjust the telescopic adjustment rod to an appropriate length to fix the beam in a horizontal state, and then adjust the angle adjustment mechanism according to the test working conditions so that the launch frame reaches the predetermined launch angle and is fixed; configure a special elastic rubber band with pre-calibrated tension and rated initial velocity indicators; select the elastic rubber band according to the initial velocity (tension) requirements selected in the test and connect the two ends of the elastic rubber band to the two elastic columns; S5. Preparation for the launch anchor test: Select a suitable power anchor, pull out the anchor cable from the anchor cable box and connect it to the tail ring of the hanging cable at the right end of the power anchor; all cameras start recording, or use the mobile phone Bluetooth to remotely control each camera, and non-test personnel evacuate the scene; the launch experimenter wears a safety helmet with a transparent mask and a protective vest, hangs the elastic rubber band in the hook hanging slot of the cable power anchor, pulls the power anchor with the elastic rubber band to the right through the trajectory control slot to the launcher slot, and the slot on the power anchor cooperates with the card block; S6. Launching the power anchor and collecting data: Turn on the laser sight, check that all preparations are correct, then pull the trigger at the bottom right end of the launcher to drive the two blocks to move downward and out of the slots in the power anchor. The power anchor is launched elastically under the action of the elastic rubber band, and the power anchor is shot through the flowing water into the underwater soil. Three cameras shoot the movement trajectory of the power anchor during penetration and the displacement when entering the soil from three angles: top view, front view, and side view (underwater). After the power anchor enters the soil, the anchor cable connected to the power anchor is passed through the first pulley and the second pulley, and connected to the dynamometer. The pulling device pulls the anchor cable, and the displayed tension and change process of the dynamometer are recorded until the power anchor is pulled out of the soil. S7. Continue to repeat tests (3) to (6) multiple times to collect penetration and extraction data of multiple power anchors; shut down the water pump and auxiliary lighting module, remove the camera, retract the power anchor and elastic rubber band, and return the safety protection equipment to its original position; S8. Test data collation and analysis: collate the test videos, photos and tension records, use Tracker software and reference coordinate system to analyze the power anchor penetration trajectory, interface shock wave, velocity attenuation, power anchor offset and power anchor burial posture data, and finally write a test report.
[0014] By adopting the above technical solution, the present invention has outstanding substantive features and significant progress compared with the prior art, as follows: 1) The base is used to place all test devices to ensure the stability of the system during the launch, penetration and pulling process. The launcher can rotate freely, and the angle adjustment mechanism can be used to adjust the launch angle. The launch force of the power anchor can be adjusted by adjusting the tension and elastic coefficient of the elastic rubber band (equipped with a special elastic conversion table), and the launch force can be adjusted and controlled according to the number and length of the elastic rubber band. The power anchor uses a special cable anchor, and the power anchor has a reverse-pull anchor barb to simulate the anchoring characteristics of the power anchor. After determining the deflection angle of the control launcher, fix one end of the selected elastic rubber band on the elastic column according to the launch force, and hang the other end into the hook groove of the power anchor, then tighten the elastic rubber band and clip it into the slot of the power anchor, and at the same time connect the anchor cable in the anchor cable box to the tail end of the power anchor, which is in a free release state; then aim at the penetration point through the laser sight, pull the trigger, drive the two card blocks to move down and out of the slot, and complete the elastic launch of the power anchor under the action of the elastic rubber band, and shoot the power anchor into the glass water tank.
[0015] 2) The glass water tank supported by a steel frame has good perspective effect and structural strength. The reference coordinate system set on the left side of the glass water tank (opposite to the power anchor launch module) is used to display the motion trajectory of the power anchor in the water, which is convenient for image tracking and analysis. The LED light strip configured at the bottom of the glass water tank is a special lighting device. After the direction and position are controlled, the light in the glass water tank is uniform, without light spots, shadows, and diffuse reflections, which is conducive to the high-speed camera to capture a clear and complete penetration process.
[0016] 3) High-speed cameras are set on the front, top and side of the glass water tank, and the height of the high-speed camera is facing the geometric center of the glass water tank; the shooting frame rate of the high-speed camera is 500fps. When the power anchor is launched, the high-speed camera is started to shoot the image of the power anchor penetration process, and the penetration process is recorded dynamically with high frame rate and high definition. The penetration process and the interface effect of the power anchor when passing through different media are completely recorded and transmitted to the computer in real time via Bluetooth function. Then the computer's built-in Tracker image analysis software draws the power anchor penetration trajectory and analyzes and calculates the anchor body offset affected by dynamic water.
[0017] 4) After the power anchor has penetrated, the anchor cable pre-connected on the power anchor is passed through the first pulley and the second pulley and then connected to the dynamometer. When pulling the anchor cable, a pulling device or manual labor can be used to make the pulling direction consistent with the penetration direction. The dynamometer records the entire process and transmits the dynamic data of the pulling force to the anchor force collector.
[0018] 5) After the penetration test, the video collected by the high-speed camera is imported into the Tracker software in the computer. By using the image tracking and analysis Tracker, the penetration trajectory of the power anchor can be drawn, the anchor body offset and interface shock wave elements can be analyzed and counted, and the speed of the power anchor at different times and in different media can be analyzed, and the speed attenuation change curve of the power anchor penetration process can be drawn.
[0019] In summary, the present invention is a multi-medium dynamic water penetration test system, which takes the penetration launch module as the core, constructs the breach dynamic water environment with large-scale circulating water tanks and soil tanks, utilizes image recognition, multi-condition cold launch and other technologies, integrates the two major functions of dynamic water penetration and anchor body pulling into one, and realizes real-time observation and research on the anchor body penetration process, interface effect, anchor body offset, and anchoring force test in a dynamic water environment.

9. A method for testing the dynamic water penetration of an emergency power anchor, which is operated by using the dynamic water penetration test system for an emergency power anchor as claimed in claim 8, characterized in that: The following steps are involved: S1. Set up soil trough: Use fine loess with a median particle size of 0.02 mm to simulate the breached riverbed soil. Place fine loess in the soil trough at the bottom of the glass water tank and compact, fill, flatten, and water it for testing; S2. Set up the video acquisition module and auxiliary lighting module: install the top-view bracket, front-view bracket and side-view bracket above, on the side and inside the glass water tank test area, respectively; install a top-view high-speed camera on the top-view bracket, a front-view high-speed camera on the front-view bracket, and a side-view waterproof high-speed camera on the side-view bracket. The shooting frame rate of each camera shall not be less than 500fps. Adjust the viewing angle and prepare for shooting; install an LED light strip around the soil trough at the bottom of the glass water tank, and install a lighting lamp on the top edge of the glass water tank to ensure sufficient light during the test period; S3. Debug the simulated breach water flow boundary: start the water pump, use the flow control solenoid valve to slowly increase the flow, adjust the water depth through the stainless steel shutter tail gate until the water depth and flow rate are controlled to meet the test conditions, record the flow, water depth, flow rate, water temperature and other parameters, and adjust the auxiliary lighting module to meet the visual transparency of the water body; S4. Debug the power anchor launch module: first level the beam using the bubble level on the beam, rotate the internal threaded sleeve to adjust the telescopic adjustment rod to an appropriate length to fix the beam in a horizontal state, and then adjust the angle adjustment mechanism according to the test working conditions so that the launch frame reaches the predetermined launch angle and is fixed; configure a special elastic rubber band with pre-calibrated tension and rated initial velocity indicators; select the elastic rubber band according to the initial velocity (tension) requirements selected in the test and connect the two ends of the elastic rubber band to the two elastic columns; S5. Preparation for the launch anchor test: Select a suitable power anchor, pull out the anchor cable from the anchor cable box and connect it to the tail ring of the hanging cable at the right end of the power anchor; all cameras start recording, or use the mobile phone Bluetooth to remotely control each camera, and non-test personnel evacuate the scene; the launch experimenter wears a safety helmet with a transparent mask and a protective vest, hangs the elastic rubber band in the hook hanging slot of the cable power anchor, pulls the power anchor with the elastic rubber band to the right through the trajectory control slot to the launcher slot, and the slot on the power anchor cooperates with the card block; S6. Launching the power anchor and collecting data: Turn on the laser sight, check that all preparations are correct, then pull the trigger at the bottom right end of the launcher to drive the two blocks to move downward and out of the slots in the power anchor. The power anchor is launched elastically under the action of the elastic rubber band, and the power anchor is shot through the flowing water into the underwater soil. Three cameras shoot the movement trajectory of the power anchor during penetration and the displacement when entering the soil from three angles: top view, front view, and side view (underwater). After the power anchor enters the soil, the anchor cable connected to the power anchor is passed through the first pulley and the second pulley, and connected to the dynamometer. The pulling device pulls the anchor cable, and the displayed tension and change process of the dynamometer are recorded until the power anchor is pulled out of the soil. S7. Continue to repeat tests (3) to (6) multiple times to collect penetration and extraction data of multiple power anchors; shut down the water pump and auxiliary lighting module, remove the camera, retract the power anchor and elastic rubber band, and return the safety protection equipment to its original position; S8. Test data collation and analysis: collate the test videos, photos and tension records, use Tracker software and reference coordinate system to analyze the power anchor penetration trajectory, interface shock wave, velocity attenuation, power anchor offset and power anchor burial posture data, and finally write a test report.
