Description

Technical Field

[0001] The invention relates to the technical field of surface runoff, and in particular to a model test box system for remotely controlling simulated surface runoff. Background Art

[0002] At present, most tests on the runoff law of the ground or building surface are carried out based on similarity ratio physical model tests or centrifugal model tests. Designing and installing indoor test equipment that can simulate different flow rates is the key work of this type of test. However, the same equipment often cannot simulate different surface runoff volumes at the same time. Therefore, the conventional practice is to replace the equipment to simulate different surface runoff volumes after each test simulation. This practice will not only increase the cost of equipment installation and commissioning, but also greatly extend the test cycle. At the same time, there is no perfect solution to the problem of water supply being difficult to ensure during long-term runoff centrifugal model tests.

[0045] The box body 1 and the water supply tank 2 are used to store and provide surface runoff water; the pressure air pipe 3 and the booster pump 4 are used to input high-pressure air into the water supply tank 2 to increase the flow rate of water flowing out of the water supply tank 2.

[0046] Assembly of the model system:

[0047] The water supply tank 2 is installed on the box body 1 by embedding the pulleys 2-1 on both sides of the water supply tank 2 into the fixed slide groove 1-5. When installing the water supply tank 2, it should be ensured that the front facade of the water supply tank is aligned with the front rectangular window 1-3; the fixed pulley 2-1 of the water supply tank slides up and down in the fixed slide groove 1-5 to adjust the height of the water supply tank 2 to adapt to model surfaces with different slopes.

[0048] Screw bolts into the booster pump mounting screw holes 4-1 on the booster pump wing plate 4-1 and the booster pump mounting reserved screw holes 1-4 on the box body 1 to fix the booster pump 4, and insert the upper and lower ends of the pressure air pipe 3 into the pressure air pipe No. 1 connecting hole 2-3 and the pressure air pipe No. 2 connecting hole 4-3 respectively, so as to realize the connection between the water supply tank 2 and the booster pump 4. The pressure air pipe 3 is a telescopic tube, and its length can be adjusted according to the relative distance between the water supply tank 2 and the booster pump 4.

[0049] Screw bolts into the drainage box installation screw holes 6-2 on the drainage box wing plate 6-1 and the drainage box installation reserved screw holes 1-8 on the box body 1 to fix the drainage box 6. When installing the drainage box, ensure that the front facade of the drainage box 6 is aligned with the rectangular window 1-6 on the back.

[0050] Screw bolts into the water pump mounting screw holes 8-2 on the water pump wing plate 8-1 and the water pump mounting reserved screw holes 1-7 on the box body 1 to fix the water pump 8, and insert the upper and lower ends of the drain pipe 7 into the drain pipe No. 1 connecting hole 6-4 and the drain pipe No. 2 connecting hole 8-3 respectively, so as to realize the connection between the drainage box 6 and the water pump 8.

[0051] Insert the two ends of the circulating water pipe 5 into the circulating water pipe No. 1 connecting hole 2-4 and the circulating water pipe No. 2 connecting hole 8-4 respectively, so as to realize the connection between the drainage tank 6 and the water supply tank 2.

[0052] Specifically, the operating principle is as follows: the opening and closing degree of the water supply grille 2-2 is controlled by the buttons a10-1 and b10-2 on the remote controller 10. The water supply grille 2-2 is similar to the openable and closable shutter structure of the automobile exhaust pipe to adjust the water flow cross-sectional area of ​​the water supply from the water tank 2 to the model surface; the output pressure value of the pressure pump 4 is controlled by the buttons c10-3 and d10-4 on the remote controller. The buttons c10-3 and d10-4 of the remote controller 10 are electrically connected to the pressure pump 4 respectively. The pressurized air enters the water tank 2 through the pressurized air pipe 3, causing the air pressure in the water tank 2 to change, thereby adjusting the water flow rate from the water tank 2 to the model surface.

[0053] The water after runoff from the model surface enters the drainage box 6 through the drainage filter 6-3. The drainage filter 6-3 can intercept the sediment carried by the water during the runoff process to avoid pipe blockage and loss of model surface quality.

[0054] The buttons e10-5 and f10-6 of the remote controller 10 are also electrically connected to the water pump 9 respectively. The power of the water pump 8 is controlled by the buttons e10-5 and f10-6 on the remote controller 10 to control the drainage efficiency of the drainage tank 6. Through the action of the water pump 8, the water in the drainage tank 6 enters the water supply tank 2 through the drain pipe 7 and the circulating water pipe 5 to achieve a balance between the water supply and drainage of the model system.

[0055] The geometrical dimensions of the model box, the power of the booster pump and the water pump and other parameters can be flexibly designed according to the similarity ratio of the model test and the test characteristics.

[0056] Compared with the prior art, the present invention has the following beneficial effects:

[0057] 1) It overcomes the shortcoming that the same surface runoff simulation equipment often cannot simulate different surface runoff volumes and runoff velocities at the same time, and saves the time and cost required to replace the surface runoff simulation equipment.

[0058] 2) The automatic circulation of water supply and drainage of the model can be realized, thus avoiding the problem of difficulty in ensuring the water supply during long-term surface runoff centrifugal model tests.

[0059] 3) It has strong applicability. By adjusting the relative height of the water supply tank and the drainage tank, it can simulate the surface runoff phenomenon on the ground with different slopes.

[0060] 4) It can be operated remotely and automatically, avoiding the disadvantages of manual operation during the test and the influence of people on the simulation test process.

[0061] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
