Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a levee seepage simulation experimental device. Background Technology

[0002] Dikes are an important component of water conservancy projects. Their main function is to prevent flooding and maintain the safety and stability of the surrounding areas. However, in actual operation, dike leakage often threatens the safety performance of dikes and may even cause serious disasters such as dike breaches. Therefore, in-depth research on the mechanism, laws and control measures of dike leakage is of great significance.

[0003] With increasing emphasis on research into seepage in dikes, related experimental studies are also increasing. Traditional methods for studying seepage in dikes mainly include field monitoring and theoretical analysis. While field monitoring can obtain seepage data from actual projects, it is limited by engineering conditions and cannot comprehensively and systematically study the impact of various factors on seepage. Theoretical analysis is mainly based on mathematical models, which derive seepage formulas and laws by establishing various assumptions and simplifying conditions. However, due to the complex geological conditions of actual dike projects, theoretical models often fail to accurately reflect the real situation and have certain limitations.

[0004] To overcome the shortcomings of on-site monitoring and theoretical analysis, a dike seepage simulation experimental device has emerged. However, the current experimental device cannot accurately simulate the slope of the real environment or the dynamic water conditions in the actual environment, and the experimental efficiency needs to be improved. In view of this, we propose a dike seepage simulation experimental device. Utility Model Content

A circular filter plate is snapped into the inner side of the water inlet end of the water outlet pipe. A door is hinged to the side of the test chamber away from the servo hydraulic cylinder.

[0010] The test chamber has a locking plate attached to one side of the bottom of the door, a drain pipe fixedly installed inside the locking plate, a valve installed on the drain pipe, a fastener installed on the door, a semi-circular filter bucket attached to the other side of the bottom of the door, and an observation window made of transparent glass fixedly installed inside the test chamber on the side near the door.

[0011] Preferably, the circular filter plate has through-holes, and the semi-circular filter barrel has through-holes on its arc-shaped sidewall, thereby filtering impurities.

[0012] Preferably, the hatch, the card plate, the drain pipe, the valve, the fastener, and the semi-circular filter barrel are provided in two sets.

The servo motor is fixedly installed on the outer side of the end of the test chamber near the water inlet pipe, and a sealed bearing is fixedly installed on the inner side of the end of the test chamber near the water inlet pipe. Two sets of sealed bearings are provided. A rotating shaft is fixedly installed at the output end of the servo motor. The rotating shaft is fixedly installed between the two sets of sealed bearings, and an impeller is fixedly installed on the outer side of the rotating shaft. Thus, the rotation of the impeller drives the water to move, thereby better simulating the moving water conditions in the actual environment.

[0014] Preferably, an L-shaped frame is fixedly installed on the outer side of the end of the test chamber away from the water inlet pipe. A servo hydraulic rod is fixedly installed on the lower surface of the top of the L-shaped frame, and a baffle is fixedly installed on the piston end of the bottom of the servo hydraulic rod. Two sets of L-shaped frames and servo hydraulic rods are provided to better prevent water from entering the chamber door during the test phase and to reduce the impact force caused by a sudden dam failure.

[0015] Preferably, a rotating cylinder is rotatably installed inside the end of the water outlet pipe away from the circular filter plate, and a water spray pipe is fixedly installed on the rotating cylinder. The water outlet pipe, the rotating cylinder, and the water spray pipe are internally connected.

[0016] Compared with the prior art, this utility model provides a dam seepage simulation experimental device, which has the following beneficial effects:

[0017] 1. This dike seepage simulation experimental device, in order to better conduct dike seepage simulation experiments, is equipped with motion components. After the dike material is formed into a dike body in the test chamber, the servo hydraulic cylinder is activated to make the hinge block rotate in the hinge seat. The swing of the test chamber facilitates the simulation of the slope of the real environment. Water can be introduced into the test chamber through the water inlet pipe and water pump. The seepage of the dike body can be monitored through the observation window. With the water outlet pipe, water outlet pump and circular filter plate, the water can be discharged to the other side of the dike body.

[0018] 2. This dam seepage simulation experimental device, in order to make the experimental process more closely resemble real water conditions and improve experimental efficiency, is equipped with auxiliary components. When the servo motor is started, in conjunction with the sealed bearing, the rotating shaft rotates, thereby rotating the impeller and driving the water to move, better simulating the moving water conditions in the actual environment. The servo hydraulic rod on the L-shaped frame is activated, allowing the baffle to move up and down. When the bottom of the baffle is in contact with the bottom surface of the test chamber, it can better prevent water from leaking into the chamber door during the test phase and also reduce the impact force of a sudden dam failure. After the test, the servo asynchronous motor is started, and the rotation of the rotating rod drives the rotating drum and water spray pipe to swing back and forth, thereby rinsing the semi-circular filter bucket to prevent the accumulation of impurities, thus making the experimental process more closely resemble real water conditions and improving experimental efficiency.

Two sets of impellers 44 on the outer side of the shaft 43 rotate accordingly, thereby causing water movement and better simulating the dynamic water conditions in a real environment. Additionally, an L-shaped frame 45 is fixedly installed on the outer side of the test chamber 33 away from the inlet pipe 36. A servo hydraulic rod 46 is fixedly installed on the lower surface of the top of the L-shaped frame 45, and a baffle 47 is fixedly installed on the piston end of the servo hydraulic rod 46. Two sets of L-shaped frames 45 and servo hydraulic rods 46 are provided. Furthermore, the inner side of the outlet pipe 38 away from the circular filter plate 310 rotates...

The water outlet pipe 38, the rotating drum 48, and the water spray pipe 49 are internally connected. Multiple sets of water spray pipes 49 are provided, and the water spray pipes 49 are located above the semi-circular filter barrel 316. When the servo hydraulic rod 46 on the L-shaped frame 45 is activated, the baffle 47 at the piston end of the servo hydraulic rod 46 can move up and down.

[0034] All electrical components appearing in this application are electrically connected to the controller and 220V AC mains power. The controller is a conventional and known device that can control the servo hydraulic cylinder 34, the inlet pump 37, the outlet pump 39, the servo motor 41, the servo hydraulic rod 46, and the servo asynchronous motor 410. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The machinery, parts, and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.

[0035] Working principle: First, the dam material is formed into dam body 35 inside the test chamber 33. When the servo hydraulic cylinder 34 is started, its piston end extends and retracts, driving the hinge block 32 to rotate in the hinge seat 31, thereby causing the test chamber 33 to swing, thus simulating the slope of the real environment. Water is input into the test chamber 33 through the water inlet pipe 36 and the water inlet pump 37. During the test, the leakage of dam body 35 can be monitored through the observation window 317. Using the water outlet pipe 38, the water outlet pump 39 and the circular filter plate 310, the water can be discharged to the other side of the dam body 35 and impurities can be filtered. When it is necessary to drain water from the chamber door 311, the water can be easily discharged from the test chamber 33 with the help of the drain pipe 313 and the valve 314, and the semi-circular filter barrel 316 can filter impurities.

[0036] Furthermore, when the servo motor 41 is started, it works with the sealed bearing 42 to drive the rotating shaft 43 to rotate. The two sets of impellers 44 on the outer side of the rotating shaft 43 rotate accordingly, thereby driving the water to move and better simulating the moving water conditions in the actual environment. When the servo hydraulic rod 46 on the L-shaped frame 45 is started, the baffle 47 at the piston end of the servo hydraulic rod 46 can move up and down. When the bottom of the baffle 47 is in contact with the bottom surface of the test chamber 33, it can prevent water from leaking into the chamber door 311 during the test phase and can also reduce the impact force caused by a sudden dam failure. After the test, the servo asynchronous motor 410 is started in both directions. Its output end drives the rotating rod 411 to rotate, thereby driving the multiple sets of water spray pipes 49 on the rotating drum 48 to swing back and forth, thereby rinsing the semi-circular filter bucket 316, avoiding the accumulation of impurities, ensuring the normal operation of the experimental device and the accuracy of the experiment, making the experimental process closer to the real water conditions and improving the experimental efficiency.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
