[0026] See also Figure 1-4 ,The utility model provides a technical solution:

[0027] A water pump experimental device comprises a fixing frame 1, a water tank 2 is fixedly arranged on the inner side of the fixing frame 1, a mounting frame 3 is fixedly arranged on the inner side of the water tank 2, a threaded rod 4 is rotatably arranged on the inner side of the mounting frame 3, a threaded block 5 is threadedly sleeved on the outer side of the threaded rod 4, a placement plate 6 is fixedly arranged on the outer side of the threaded block 5, a driving motor 7 is fixedly arranged on the upper side of the mounting frame 3, a power end of the driving motor 7 movably penetrates the mounting frame 3 and is fixedly connected to the threaded rod 4, a transparent window 10 is fixedly arranged on the outer side of the water tank 2, a scale mark 11 is arranged on the outer side of the transparent window 10, a supporting block 12 is fixedly arranged on the upper side of the fixing frame 1, a placement table 13 is fixedly arranged on the upper side of the supporting block 12, and a noise meter 14 is movably arranged on the upper side of the placement table 13. By testing the noise conditions of the water pump at different water depths, some noise laws of the water pump can be obtained, such as the noise value of the water pump at a water depth of 20 centimeters, the noise value at a water depth of 30 centimeters, and so on, so as to facilitate and quickly conduct noise experiments on the water pump.

[0028] Specifically, a limiting groove 8 for docking with the threaded block 5 is opened on the inner side of the installation frame 3. The threaded block 5 slides in the limiting groove 8. The limiting groove 8 can limit the threaded block 5, so that when the threaded rod 4 rotates, it can drive the threaded block 5 to move up and down along the threaded rod 4, thereby facilitating the up and down movement of the placement plate 6 and the water pump, thereby improving the movement stability of the placement plate 6.

[0029] Furthermore, a laser lamp 9 is fixedly provided on the outside of the placement plate 6, and a plurality of leakage holes are provided through the placement plate 6 from top to bottom. When the placement plate 6 moves, it can drive the laser lamp 9 to move, and the laser lamp 9 can illuminate the transparent window 10, so that the staff can quickly know the depth of the water pump and improve the convenience of use.

[0030] It is worth mentioning that two groups of fixed frames 15 are fixedly arranged on the inner side of the placement table 13, and sliders 16 are movably arranged on the inner sides of the two groups of fixed frames 15. A connecting rod 17 is fixedly arranged on the outer side of the slider 16, and a clamping plate 18 is fixedly arranged on the outer end of the connecting rod 17. The clamping plate 18 movably passes through the placement table 13 and extends to the upper side, and a limiting spring 19 is arranged on the inner side of the fixed frame 15, one end of the limiting spring 19 is connected to the inner side of the fixed frame 15, and the other end of the limiting spring 19 is connected to the slider 16. The limiting spring 19 is initially in an elastic shape, and the elasticity of the limiting spring 19 can drive the clamping block 18 to clamp the noise meter 14, thereby ensuring the stability of the noise meter 14. At the same time, it is convenient to fix noise meters 14 of different sizes, and the practicality is better.

[0031] It is worth noting that a connecting block 20 is fixedly provided on the upper side of the slider 16, the connecting block 20 movably passes through the fixed frame 15 and extends to the upper side, and a push plate 21 is fixedly provided on the upper side of the connecting block 20 located on the upper part of the fixed frame 15. By pulling the push plate 21, the connecting block 20 can be easily moved, thereby facilitating the movement of the intercepting stem 17 and the splint 18, further improving the convenience of loading and unloading the noise meter 14.

[0032] In addition, the fixed frame 15 is provided with a slide groove 22 for docking the connecting block 20 from top to bottom. The slide groove 22 can facilitate the movement of the connecting block 20 on the one hand, and can also limit the connecting block 20 to prevent the connecting block 20 from deviating, thereby ensuring the movement stability of the slider 16 and the splint 18.

[0033] It must be said that an anti-skid pad 23 is fixedly provided on the outer side of the splint 18. The anti-skid pad 23 is made of soft material. By providing the soft anti-skid pad 23, on the one hand, the fixing effect of the noise meter 14 can be improved to prevent the noise meter 14 from slipping, and at the same time, the noise meter 14 will not be damaged.

[0034] Working principle: first fill the water tank 2 with water, then place the noise meter 14 between the two sets of clamps 18, and use the elasticity of the limit spring 19 to drive the clamp 18 to clamp the noise meter 14, then place the water pump on the upper side of the placement plate 6, and then turn on the drive motor 7 and the water pump through an external power supply. The drive motor 7 drives the threaded rod 4 to rotate, and the threaded block 5 sleeved on the outside of the threaded rod 4 moves downward along the threaded rod 4 under the limiting action of the limit groove 8. When the threaded block 5 moves downward, it drives the placement plate 6 and the water pump to move. When the water pump moves to a certain position, the noise generated when the water pump is working can be tested by the noise meter 14. At this time, the laser light 9 illuminates the transparent window 10, and the scale mark 11 corresponding to the transparent window 10 can conveniently obtain the depth of the water pump, so as to facilitate the experiment of the noise of the water pump under different depths.
