Description

Technical Field

[0001] This utility model relates to the field of water flow experiment demonstration technology, and in particular to a water flow experiment demonstration platform. Background Technology

[0002] With the progress of the times, people are very interested in the speed and state of water flow. Through a series of experiments, they explore water flow to discover its other functions. When conducting water flow experiments in the laboratory, a water flow experiment demonstration platform is needed to demonstrate the experimental operation. Only after the water flow experiment demonstration can we know whether the experimental data and results are qualified.

[0003] When conducting a water flow experiment in the laboratory, the slope of the water tank is first adjusted using a lifting machine. Once the slope is adjusted to the appropriate position, the water pump is started to raise the water in the constant pressure tank to the water tank. The movement of the water flow is observed in the water tank, and the water flow is intercepted and released using a gate. The water flows through the return water tank into the return water pipe, and finally returns to the constant pressure tank, completing a water flow experiment demonstration process.

[0004] Of course, some water flow experiments need to be combined with actual conditions. This requires adding something to the experiment, such as sand. However, most of the return water tanks on the market are straight pipes. If mud and sand enter the pipes and accumulate in the return pipes, it will cause blockage of the return water pipes, resulting in poor water flow or slow water return. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a water flow experiment demonstration platform, which aims to improve the problem of preventing sediment from accumulating in the water pipes and causing blockage of the return pipe when conducting water flow experiments containing sediment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water flow experiment demonstration platform, including a constant pressure water tank, a water trough on the right side of the constant pressure water tank, a second water pipe fixedly connected to one side of the water trough, a splash-proof shell on the outer wall of the second water pipe, a return water tank on the lower surface of the second water pipe, a mud and sand prevention mechanism inside the return water tank, and a splash-proof mechanism on the top of the return water tank; The anti-sludge mechanism includes a support column, the lower surface of which is fixedly connected to the inner wall of the return water tank, a spring fixedly connected to the upper surface of the support column, a pressing plate fixedly connected to one end of the spring, and the other end of the spring fixedly connected to the upper surface of the support column. A pressing column is fixedly connected to the lower surface of the pressing plate, a locking column is fixedly connected inside the pressing column, a rotating column is provided on one side of the support column, a rotating plate is fixedly connected to the outer wall of the rotating column, and a nylon plate is fixedly connected to the lower surface of the rotating plate.

[0007] Furthermore, the splash-proof mechanism includes a splash-proof shell, a return water tank is provided on the lower surface of the splash-proof shell, a rotating rod is fixedly connected to the outer wall of the splash-proof shell, a locking block is fixedly connected to the outer wall of the splash-proof shell, and a locking plate is rotatably connected to the outer wall of the rotating rod.

[0008] Furthermore, the water tank has a groove inside, a gate is slidably connected to the inner wall of the water tank, and a lift is provided on the lower surface of the water tank.

[0009] Furthermore, a support frame is fixedly connected to the lower surface of the constant pressure water tank, and a first water pipe is fixedly connected to the lower surface of the constant pressure water tank.

[0010] Furthermore, a water pump box is fixedly connected to one end of the first water pipe, the water pump box contains a water pump, the output end of the water pump is fixedly connected to the first water pipe, and a return water pipe is fixedly connected to the right side of the water pump box.

[0011] Furthermore, the upper surface of the support frame is fixedly connected to the lower surface of the elevator, a support plate is fixedly connected to the lower surface of the support frame, and a wheel is fixedly connected to the lower surface of the support plate.

[0012] Furthermore, the lower surface of the return water tank is fixedly connected to the upper surface of the return water pipe, and the outer wall of the retaining column is slidably connected to the inside of the support column.

[0013] Furthermore, the splash guard has a semi-circular hole to allow the second water pipe to pass through.

[0014] This utility model has the following beneficial effects: 1. In this utility model, water is pumped into a constant pressure water tank by a water pump, and then the slope of the water tank is adjusted by a lift to observe the movement and speed of the water flow. The combination of nylon plate and nylon net can effectively retain sediment in the return water tank, preventing sediment from falling into the water pipe and causing blockage at the bottom of the water pipe, thus preventing water from returning to the constant pressure water tank through the return water pipe. At the same time, the nylon plate can be flipped over to replace the nylon net, effectively solving the problem of sediment accumulation on the nylon net, which causes the water to flow downward slowly, resulting in slow return and affecting the next water flow experiment demonstration.

[0015] 2. In this utility model, by installing a splash-proof mechanism above the return water tank, the problem of water splashing out when flowing into the return water tank is effectively solved because the slope of the water tank is changed by the elevator, which changes the flow speed of the water. At the same time, the splash-proof shell can be easily disassembled and installed above the water tank by using the card plate and card block. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1-4 An embodiment of this utility model is provided: a water flow experiment demonstration platform, including a constant pressure water tank 1, a water tank 2 is provided on the right side of the constant pressure water tank 1, the water tank 2 is L-shaped and the other end is connected to a second water pipe 10, a splash shield 11 is provided on the outer wall of the second water pipe 10, a return water tank 12 is provided on the lower surface of the second water pipe 10, a mud and sand prevention mechanism is provided inside the return water tank 12, and a splash prevention mechanism is provided on the top of the return water tank 12; The anti-sludge mechanism includes a support column 21, the lower surface of which is fixedly connected to the inner wall of the return water tank 12. A spring 20 is fixedly connected to the upper surface of the support column 21. One end of the spring 20 is fixedly connected to a pressing plate 19, and the other end of the spring 20 is fixedly connected to the upper surface of the support column 21. A pressing column 23 is fixedly connected to the lower surface of the pressing plate 19. A locking column 24 is fixedly connected inside the pressing column 23. A rotating column 22 is provided on one side of the support column 21. A rotating plate 18 is fixedly connected to the outer wall of the rotating column 22. A nylon plate 17 is fixedly connected to the lower surface of the rotating plate 18. A groove is provided inside the water tank 2. A gate 3 is slidably connected to the inner wall of the water tank 2. A lift 9 is provided on the lower surface of the water tank 2. A support frame 4 is fixedly connected to the lower surface of the constant pressure water tank 1.

[0020] Specifically, by pressing the nylon mesh onto the nylon plate 17, pressing the pressing plate 19 and squeezing the spring 20, the pressing post 23 connected to the pressing plate 19 is pressed downwards, along with the locking post 24, until the locking post 24 moves out of the support post 21. This allows the nylon plate 17 to rotate. After replacing the nylon mesh, the nylon plate 17 is placed back in place, and the pressing plate 19 is released. The elastic force of the spring 20 will cause the pressing plate 19 to rebound upwards, driving the pressing post 23 upwards. At the same time, the locking post 24 also moves upwards and enters the locking groove in the support post 21, thus fixing the nylon plate 17 in place. Finally, the water flows from the nylon plate 17 into the return water pipe 13, and then back into the constant pressure water tank 1 in the return pipeline formed by the return water pipe 13. Using the nylon plate 17 and the nylon mesh together can effectively keep the sediment in the return water tank 12, preventing sediment from falling into the water pipe and causing blockage at the bottom of the water pipe.

[0021] Reference Figure 1-5 The splash-proof mechanism includes a splash-proof shell 11, a return water tank 12 on the lower surface of the splash-proof shell 11, a rotating rod 15 fixedly connected to the outer wall of the splash-proof shell 11, a locking block 16 fixedly connected to the outer wall of the splash-proof shell 11, a locking plate 14 rotatably connected to the outer wall of the rotating rod 15, a semi-circular hole in the splash-proof shell 11 to allow the second water pipe 10 to pass through, a first water pipe 5 fixedly connected to the lower surface of the constant pressure water tank 1, a water pump box 6 fixedly connected to one end of the first water pipe 5, a water pump box 6 containing a water pump, and the output end of the water pump fixedly connected to the first water pipe 5, a return water pipe 13 fixedly connected to the right side of the water pump box 6, a support frame 4 fixedly connected to the lower surface of the elevator 9, a support plate 7 fixedly connected to the lower surface of the support frame 4, a wheel 8 fixedly connected to the lower surface of the support plate 7, a return water tank 12 fixedly connected to the upper surface of the return water pipe 13, and a locking post 24 slidably connected to the inner wall of the support post 21.

[0022] Specifically, when conducting a water flow experiment demonstration, the water tank 2 is first raised using the elevator 9 to change its slope. Then, the water pump in the pump box 6 is started to pressurize the water in the constant pressure tank 1 into the water tank 2. The water in the water tank 2 changes speed due to the slope and flows to the other side. The gate 3 in the water tank 2 can then be used to intercept and release the water, changing the flow speed again and observing the dynamics of the water flow. When the water flows into the return water tank 12, the clamps 14 on both sides of the splash shield 11 are engaged. Rotating the rotating rod 15 engages the groove on the clamping plate 14 with the clamping block 16, thus securing the splash guard 11. By installing a splash guard above the return water tank 12, the problem of water splashing when flowing into the return water tank 12 is effectively solved, as the slope of the water tank 2 is changed by the elevator 9, which alters the flow speed of the water. At the same time, the clamping plate 14 and the clamping block 16 allow for easy disassembly and installation of the splash guard 11 above the return water tank 12.

[0023] Working principle: When conducting a water flow experiment demonstration, the water tank 2 is first lifted by the elevator 9 to change its slope. Then, the water pump in the pump box 6 is started to pressurize the water in the constant pressure tank 1 into the water tank 2. The water in the water tank 2 changes speed due to the slope and flows to the other side of the water tank 2. Then, the gate 3 in the water tank 2 can be used to intercept and release the water, changing the water flow speed again and observing the dynamics of the water flow. When the water flows to the return water tank 12, the clamping plates 14 on both sides of the splash shield 11 are rotated by the rotating rod 15 to lock the grooves on the clamping plates 14 into the clamping blocks 16, thus simply fixing the splash shield 11. When the water flows into the return water tank 12, it is pressed against the nylon plate. Place the nylon mesh on plate 17, press down on the pressing plate 19 and squeeze the spring 20, causing the pressing post 23 connected to the pressing plate 19 to press down together, along with the locking post 24, until the locking post 24 moves down out of the support post 21. This allows the nylon plate 17 to rotate. After replacing the nylon mesh, place the nylon plate 17 in place and release the pressing plate 19. The elastic force of the spring 20 will cause the pressing plate 19 to rebound upward, driving the pressing post 23 upward. At the same time, the locking post 24 also moves upward and enters the locking groove in the support post 21, thus fixing the nylon plate 17 in place. Finally, the water flows from the nylon plate 17 into the return water pipe 13, and then flows back to the constant pressure water tank 1 in the return pipeline formed by the return water pipe 13.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
