Description

Technical Field

[0001] This utility model relates to the field of gate technology, and in particular to a fast-opening gate for gravity impact simulation experiments. Background Technology

[0002] Impact simulation test gates are used to simulate the impact force and response of debris flows on structures (such as gates, dams, pipelines, etc.), aiming to help design and optimize protective facilities to ensure effective resistance to impacts in actual debris flow disasters.

[0003] These experimental gates are adjustable, capable of simulating different flow rates, particle sizes, and impact pressures of debris flows, while possessing sufficient strength and durability to withstand the impact forces of debris flows. The gates are equipped with a sophisticated control system that can adjust the opening and closing speeds to simulate different debris flow impact scenarios.

[0004] In summary, existing simulated impact devices still have the following technical problems: Debris flows are usually caused by factors such as heavy rainfall, snowmelt, or earthquakes, which cause a large amount of loose soil and rock material to slide down steep slopes rapidly, forming a mixed mud flow. Debris flows towards lower altitudes have a stronger impact force. Existing simulated impact devices generally only increase the flow rate of water, but this kind of simulation requires a large site. If the site is small, the impact force of the water flow will not meet the simulation requirements. Therefore, it is necessary to propose a gravity impact simulation experiment quick-opening gate to provide a new technical solution to solve the technical problems mentioned in the above patent.

[0028] The gravity impact simulation experiment quick-opening gate provided by this utility model, by setting a counterweight 9 in conjunction with the gate 20, can achieve water accumulation inside the water storage tank 1 after the gate 20 blocks the water storage tank 1. After completion, the gravitational potential energy of the descending counterweight 9 drives the gate 20 to flip instantly and release the water inside the water storage tank 1, thus simulating the impact of debris flow. This method can greatly reduce the experimental space and simulate the real impact effect of debris flow in a shorter distance.

[0031] The support frame 3 has a fixed seat 10 inside, and a hanging rod 11 is fixedly connected to the bottom end of the fixed seat 10. A fixing clamp 13 is provided at the end of the hanging rod 11 away from the fixed seat 10. A cable 18 is connected to the top of the counterweight 9.

[0034] Specifically, a first fixed pulley 16 is fixedly connected to the top of the support frame 3, a second fixed pulley 17 is fixedly connected inside the support frame 3, a lifting ring 15 is fixedly connected to the top surface of the counterweight block 9, a cable 18 is fixedly connected to the counterweight block 9 through the lifting ring 15, a connecting ring 21 is fixedly connected to the surface of the gate 20, and the cable 18 passes through the first fixed pulley 16 and the second fixed pulley 17 and is fixedly connected to the gate 20 through the connecting ring 21.

[0035] Specifically, a control rod 14 is fixedly connected inside the support frame 3, and the end of the control rod 14 away from the support frame 3 is connected to the fixing clamp 13.

[0036] Specifically, a limit block 22 is fixedly connected to one side of the water storage tank 1, and a telescopic control rod 23 is fixedly connected to the side of the gate 20 away from the connecting ring 21.

As the counterweight 9 descends, the cable 18 is pulled to make the gate 20 rotate around the hinge seat 19 to stop blocking the water storage tank 1. At this time, the water inside the water storage tank 1 pours out instantly, thereby simulating the impact of a mudslide. As the counterweight 9 descends, it is buffered by the buffer pad 7.
