Description

Technical Field

[0001] This utility model relates to the technical field of experimental demonstration equipment, specifically a demonstration device for flooding of an earthen dam. Background Technology

[0002] Overtopping demonstration devices for earthen dams are miniaturized experimental devices used to simulate and study the potential for dam failure after the dam crest is submerged (i.e., overtopping) during super-floods or other emergencies. These devices help researchers and engineers understand the overtopping failure process, assess potential hazards, and test different protective measures. Demonstration devices are not only used for scientific research but also frequently for educational purposes, enabling students to visually understand the importance of earthen dam safety and the severe consequences of overtopping failure. Furthermore, these devices may be used to train emergency responders, improving their awareness and ability to respond to potential disasters.

[0003] The demonstration device simulating the flooding of an earthen dam is not only a teaching tool but also a practical platform, allowing students to experience the importance of safety in a simulated real-world scenario. During the operation, students need to carefully observe the process of the dam flooding, analyzing how factors such as rising water levels, changes in water flow velocity, and increased pressure on the dam interact to ultimately lead to instability or collapse. This process vividly illustrates the philosophical principle that "quantitative change accumulates to a certain degree and triggers qualitative change," enabling students to deeply understand the complexity and severity of safety issues.

[0004] Existing earth dam flooding demonstration devices are not convenient for detecting water level, dam height, and dam collapse displacement during use, which leads to increased uncertainty and error in experimental results. Moreover, the lack of precise data support makes it difficult to conduct in-depth quantitative analysis of dam stability, flooding process, and ultimate dam failure mechanism. Utility Model Content

It solves the problem that existing demonstration devices for the flooding of earthen dams are not convenient for detecting water level, dam height, and dam collapse displacement during use, which leads to increased uncertainty and error in experimental results. Moreover, the lack of accurate data support makes it difficult to conduct in-depth quantitative analysis of the stability of earthen dams, the flooding process, and the final dam failure mechanism.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a demonstration device for flooding of an earthen dam, comprising a base, a demonstration box, a detection component, a water tank and a water pump fixedly installed on the top of the base, a water supply pipe connected to the outlet of the water tank, a flow valve connected to the outlet of the water supply pipe, and the flow valve fixedly installed at the bottom right side of the demonstration box and connected to its inner cavity.

[0007] The detection component includes a support rod, the bottom of which is fixedly connected to the top of the base, a fixing frame is fixedly connected to the top of the support rod, and an angle adjustment component is fixedly installed at the bottom of the fixing frame;

[0008] The angle adjustment assembly includes a mounting plate, a stepper motor is fixedly connected to the rear side of the mounting plate, a rotating rod is fixedly connected to the output shaft of the stepper motor, a rotating component is fixedly sleeved on the surface of the rotating rod, a slope displacement detection sensor is fixedly connected to one end of the rotating component, and a connecting frame is fixedly connected to the top of the mounting plate, with the top of the connecting frame fixedly connected to the bottom of the fixed frame.

[0013] As a preferred demonstration device for flooding of an earthen dam according to this utility model, a communication control module is also fixedly installed on the top of the base.

[0014] As a preferred demonstration device for flooding of an earthen dam according to this utility model, the top of the earthen slope height detection sensor and the liquid level height detection sensor are slidably connected to the bottom of the mounting frame.

The simulated water is located on the right side of the earthen dam. The liquid level detection sensor is located at the top of the simulated water to detect its liquid level. The earth slope height detection sensor is located at the top of the earthen dam to detect its height. The slope displacement detection sensor is located on the left side of the earthen dam to detect its slope.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model uses a first electric telescopic rod to move a slope height detection sensor to the top of the earth dam, and a second electric telescopic rod to move a liquid level detection sensor to the top of the simulated water. A stepper motor drives a rotating rod and a rotating component to rotate, and the rotating component drives a slope displacement detection sensor to rotate, so that the detection position of the slope displacement detection sensor is aligned with the slope on the left side of the earth dam.

[0018] 2. This utility model uses a water pump to draw water from an external source and injects it into a water tank through a delivery pipe. A liquid level sensor detects the liquid level inside the tank. When the set liquid level is reached, the water pump is automatically shut off. After the water injection is complete, the flow valve is opened, and water is added to the demonstration tank through the water inlet pipe to form simulated water. The changes in the liquid level detection sensor data are observed and the process of water level rise is recorded. Earth slope height detection sensors and slope displacement detection sensors are used to monitor changes in the earth dam, especially when the water level gradually rises to the top of the earth dam. When the water level exceeds the top of the earth dam, the state changes of the earth dam are continuously observed. Data from all sensors are collected and recorded, including water level, earth dam height changes, and slope changes. By analyzing the data, the stability of the earth dam and the possibility of dam failure are assessed. Attached Figure Description
