Description

Technical Field

[0001] The utility model relates to the technical field of aerators, in particular to a drainage system demonstration device. Background Art

[0002] A drainage demonstration device is a device used to demonstrate the drainage performance of drainage parts. When designing the existing water supply and drainage system, the functional speed of the drainage system needs to be tested. The system pipe fittings can be replaced by scaled-down substitutes for actual demonstration to measure the drainage function of the designed system. However, most of the demonstration devices are for one-time operation. Pour a certain amount of water at the top, measure the time required for the water to empty from the bottom, and detect the drainage efficiency of the pipe fittings to empty. Then stop the detection, empty or collect the clear water below, and pour it from the top for a second demonstration. The demonstration continuity is poor. At the same time, it is extremely troublesome to replace when testing the drainage of different pipes. In view of this, we propose a pipe drainage function demonstration device.

[0003] In view of the problems in the prior art, those skilled in the art have improved it. For example, a pipe drainage function demonstration device with the publication number of CN221175647U includes a housing. A water supply and drainage model installation part is arranged in the housing. The water supply and drainage model installation part supplies the drainage model to be vertically installed. A water supply component is arranged at the top of the housing, and a water accumulation part is arranged at the bottom of the housing. The utility model has a reasonable structure. The water storage tank can provide demonstration water. The water flowing through the drainage system model will have its water inflow and drainage volume detected in real time to obtain digital demonstration data. A circulating water channel is installed on the water storage tank to push the water below upward to prevent it from accumulating at the water outlet position at the bottom of the drainage system model and affecting the smooth water discharge. And the water storage tank can be replenished with water at any time for continuous demonstration. The disadvantage of this device is that it is extremely troublesome to replace when testing the drainage of different pipes.

[0004] To sum up, it is obvious that the prior art has inconveniences and defects in actual use, so it is necessary to improve it. Content of the Utility Model

A water collection tank 13 is arranged inside the demonstration box 6, and the water collection tank 13 is fixedly connected to the inner bottom of the demonstration box 6. A water distribution pipe 7 is arranged above the water collection tank 13. The drain pipes 2 pass through the demonstration box 6 and are fixedly connected to both ends of the water distribution pipe 7. A plurality of telescopic pipes 701 are penetrated on the water distribution pipe 7. Clamps are fixedly connected to one ends of the telescopic pipes 701. A sliding frame 8 is fixedly connected to the telescopic pipes 701. A driving member 9 is arranged on one side of the sliding frame 8, and the driving member 9 is fixedly connected to the inner bottom of the demonstration box 6. Screw rods 11 are arranged on both sides of the driving member 9. Threaded blocks 12 are threadedly connected to both ends of the screw rods 11, and both ends of the screw rods 11 are respectively rotatably connected to the inner top and inner bottom of the demonstration box 6.

[0021] See Figures 1 to 3 , in a further embodiment, the thread directions of the upper and lower ends of the screw rod 11 are opposite.

After the installation is completed, the output shaft of the driving member 9 rotates in reverse, the screw rod 11 drives the threaded blocks 12 to move away from each other, and then the cross-bar group 10 drives the sliding frame 8 to move away from the opening of the demonstration box 6, and then retracts the telescopic tube 701 and the demonstration pipe to conduct a drainage demonstration. When demonstrating, the valve 5 will be closed to prevent the water in the drain pipe 2 from flowing into the circulation pipe 3. When the water in the drain pipe 2 is emptied, the valve 5 will be opened to pump the water in the water pumping tank 14 back to the drain pipe 2 through the circulation pipe 3.
