However, the pressure and speed of the fluid at the fluid outlet of the existing experimental teaching instrument are not stable, so that the experimental measurement of students (experimenters) is greatly influenced; and the existing water tank is easy to accumulate water to generate accumulated water, so that moss at the wall of the water tank grows, and the cleaning workload and difficulty of the instrument are greatly increased. Therefore, the water tank device which can prevent water accumulation and has the rectifying effect is required in teaching.

A water accumulation preventing hydraulic experiment water tank comprises a water accumulation preventing inverted round table, an outer cylinder, an overflow cylinder and a rectifying cylinder; the bottom of the ponding-preventing reverse round table is provided with a water inlet connected with a water inlet pipe, a water outlet connected with a water outlet pipe and a ponding water outlet; the outer cylinder is fixed at the top end of the water accumulation preventing inverted round table, and is provided with a water outlet; the upper end opening and the lower end of the overflow cylinder are fixed at the bottom of the inverted circular table and are communicated with the water outlet; the upper end of the rectifying cylinder is provided with an opening, the lower end of the rectifying cylinder is fixed at the bottom of the inverted circular table and covers the water inlet, the water outlet and the water accumulation outlet, the lower end of the rectifying cylinder is uniformly provided with water accumulation preventing holes which enable the inner side and the outer side of the rectifying cylinder to be communicated, and the pipe wall of the rectifying cylinder is uniformly provided with rectifying small holes.
Further, the rectifying small holes are uniformly distributed on the pipe wall of the rectifying cylinder in a right spiral mode.
Further, the water outlet is positioned at the center of the bottom of the water accumulation preventing reverse round table.
Furthermore, the water inlet, the water outlet and the ponding water outlet all adopt internal thread structures.
The invention has the following advantages:
1) The bottom of the water tank adopts an inverted round platform structure, so that water drops on the pipe wall are not easy to remain on the pipe wall, and the growth of moss on the pipe wall can be effectively prevented;
2) Compared with the traditional rectangular water tank, the water tank has no boundary and included angle of four sides, and the cleanliness of the water tank is improved;
3) The bottom of the rectifying cylinder is provided with a water accumulation preventing hole, so that the water accumulation between the rectifying cylinder and the water accumulation preventing reverse round table at the outermost layer of water tank area can flow into the inner ring drainage area, and the residual water accumulation at the bottom of the outermost layer of water tank is prevented.

Detailed Description
The invention will now be described in detail with reference to the drawings and specific examples. The present embodiment is implemented on the premise of the technical scheme of the present invention, and a detailed implementation manner and a specific operation process are given, but the protection scope of the present invention is not limited to the following examples.
The embodiment of the invention is shown with reference to figures 1-4, and the water accumulation preventing hydraulic experiment water tank comprises a water accumulation preventing inverted round table 8, an outer cylinder 6, an overflow cylinder 4 and a rectifying cylinder 5.
As shown in fig. 4, the bottom of the ponding-preventing reverse round table 8 is provided with a water inlet 1 connected with a water inlet pipe, a water outlet 2 connected with a water outlet pipe and a ponding water outlet 3.
The outer cylinder 6 is fixed at the top end of the ponding-preventing reverse round table 8, and the outer cylinder 6 is provided with a water outlet 7.
The upper end opening and the lower end of the overflow cylinder 4 are fixed at the bottom of the inverted circular table 8 and are communicated with the water outlet 2. The water outlet 2 is positioned at the center of the bottom of the water accumulation preventing reverse round table 8.
As shown in fig. 3, the upper end of the rectifying cylinder 5 is opened, the lower end of the rectifying cylinder is fixed at the bottom of the inverted circular table 8 and covers the water inlet 1, the water outlet 2 and the water accumulation outlet 3, water accumulation preventing holes 10 which enable the inner side and the outer side of the rectifying cylinder 5 to be communicated are uniformly formed in the lower end of the rectifying cylinder 5, and rectifying small holes 9 are uniformly formed in the pipe wall of the rectifying cylinder 5. The rectifying small holes 9 are uniformly distributed on the pipe wall of the rectifying cylinder 5 in a right spiral manner.
As shown in fig. 1-2, the water inlet 1, the water outlet 2 and the accumulated water drain hole 3 are all of screw hole structures, so that the inlet and outlet drain pipelines can be conveniently installed, and valve-closing can be carried out by installing valve-equipped pipe sections; or the hose section can be externally connected, and then the hose is clamped.
When the experiment is carried out, the device is firstly connected into a hydraulic experiment device through the water outlet hole 7, the water inlet 1 is connected with the water inlet pipe, and the water outlet 2 and the ponding water outlet 3 are connected with the water outlet pipe; then closing the pipeline connected with the ponding water drain hole 3, and enabling water flow to flow into the water tank from the inlet 1, overflow through the ponding prevention hole 10 and the rectifying small hole 9 and enter the area between the rectifying cylinder 5 and the outer wall of the water tank; as the water level increases, water begins to flow out of the water outlet 7, supplying water to the experiment. When the water level of the water tank reaches the height of the overflow cylinder 4, water enters the overflow cylinder 4 and is discharged from the water outlet 2 at the bottom of the water tank, so that the liquid level is constant at the height of the overflow cylinder 4; after the experiment is completed, the power supply of the water supply pump is turned off, so that the liquid level of the water tank starts to drop; when only accumulated water is left in the water tank liquid level discharge, a pipeline associated with the accumulated water discharge hole 3 is opened to perform accumulated water discharge.
What is not described in detail in this specification is prior art known to those skilled in the art.
