When the rotating unit 6 works, water flow pushes the second water wheel 62 to rotate, the water wheel rotates to drive the rotating shaft 61 to rotate, the rotating shaft 61 drives the first bevel gear 63 to rotate, the first bevel gear 63 rotates to drive the second bevel gear 64 to rotate, and the second bevel gear 64 rotates to drive the flow stabilizing pipe 53 to rotate; the flow stabilizing unit 5 is also operated while the rotating unit 6 is operated, and the rotating unit 6 also drives the flow stabilizing pipe 53 to rotate in the process of pumping water by the flow stabilizing unit 5; under the cooperation of the steady flow unit 5 and the rotating unit 6, the water flow near the steady flow pipe 53 is sucked into the steady flow pipe 53, the direction of the water flow is changed at the moment, and the water flow with changed direction and the water flow forming vortex interfere with each other, so that the generation of the vortex is finally avoided, the water flow of a drainage pump station is discharged stably and uniformly, and the performance and stability of the drainage pump station are improved;
after the flow stabilizing unit 5 and the rotating unit 6 are matched with each other, the working effects of the flow stabilizing unit 5 and the rotating unit 6 are compared under the water drainage pump station, firstly, as shown in fig. 8 to 9, no flow stabilizing unit 5 and no rotating unit 6 are arranged in the front pool 2 and the water inlet pool 3 of the water drainage pump station, vortex is generated in the flowing process of water flow, the normal flowing of the water flow is greatly influenced by the vortex, the water flow originally flowing to the area in the front direction flows to other areas due to the fact that the direction of the vortex is changed, the water flow distribution is uneven, the water flow flowing out of the water drainage pump station is disturbed, and the working efficiency of the water drainage pump station is reduced; after the steady flow unit 5 and the rotating unit 6 are arranged in the front pool 2 and the water inlet pool 3, the direction of water flow is changed, and the flow speed of the water flow in the steady flow pipe 53 is accelerated, so that pressure difference is generated between the inside and the outside of the steady flow pipe 53, and the water flow is sucked into the steady flow pipe 53 through the through hole 59, thus forming interference with the water flow forming vortex, and the direction of the water flow is returned to the positive rail; meanwhile, the detailed simulation analysis is carried out on the water yield of each area of the water inlet tank 3 to obtain a line diagram shown in fig. 10, under the condition that the steady flow unit 5 and the rotary unit 6 are not installed, the flow difference of each area of the water inlet tank 3 is very large, and after the steady flow unit 5 and the rotary unit 6 are installed, the flow of each area of the water inlet tank 3 is relatively stable above and below the point A, which means that the working efficiency of a drainage pump station is higher and more stable after the steady flow unit 5 and the rotary unit 6 are installed; the analysis is carried out while the total flow distribution uniformity comparison chart shown in fig. 11 is obtained, and compared with the total flow distribution uniformity without the flow stabilizing pipe 53, the total flow distribution uniformity with the flow stabilizing pipe 53 is higher, which means that the water discharge pump station can achieve uniform flow distribution by installing the flow stabilizing unit 5 and the rotating unit 6 in the front tank 2 and the water inlet tank 3, the effect of high work efficiency is achieved, and meanwhile, the damage to the water discharge pump station caused by uneven flow distribution is avoided.
Example 3 based on the above example 1, as shown in fig. 6, as a preferred embodiment of the present invention, four flow stabilizing pipes 53 are uniformly distributed in the water inlet tank 3; the four steady pipes 53 are exactly in one-to-one correspondence with the four areas separated by the barrier 4; the front pool 2 and the water inlet pool 3 are divided into four areas by four flow stabilizing pipes 53, so that the space for flowing water can be compressed; because the area that each flow stabilizing pipe 53 can influence is limited, setting the flow stabilizing pipes 53 to four can also better prevent the water flow from generating bad flow states such as backflow, vortex and the like after entering the forehearth 2.
Example 4 based on the above-mentioned example 1, as shown in fig. 6, as a preferred example of the present invention, the flow stabilizing tube 53 is provided with a rectangular through hole 59, the rectangular through hole 59 is less likely to be blocked than a circular through hole, and the water inlet of the rectangular through hole 59 is smoother than a circular through hole.
Embodiment 5 based on the above embodiment 1, as shown in fig. 6, as a preferred embodiment of the present invention, rectangular through holes 59 in the flow stabilizing tube 53 are distributed in a staggered manner, and compared with regular array distribution, the staggered distribution of the rectangular through holes 59 can better interfere with the direction of the water flow, thereby avoiding the generation of vortex and improving the stability of the water flow.
Embodiment 6 on the basis of the above embodiment 1, as shown in fig. 1 to 2, as a preferred embodiment of the present invention, the water inlet is provided with a water level gauge 12, and the water inlet is provided with the water level gauge 12 for monitoring the water level in the drain pump, so as to prevent the overload operation of the drain pump station and influence the working efficiency of the drain pump station.
Embodiment 7 on the basis of the above embodiment 1, as shown in fig. 7, as a preferred embodiment of the present invention, the pipe rack 51 adopts an H-shaped structure, and the pipe rack 51 adopts an H-shaped structure, so that the blocking effect of the pipe rack 51 on the water flow can be reduced, and the area of the water flow hitting the pipe rack 51 is effectively reduced, thereby avoiding the reduction of the flow velocity of the water flow; the reduced flow rate of the water flow results in reduced rotational speeds of the first and second water wheels 55, 62, which results in insufficient power in the displacement pump station.
Embodiment 8 based on the above embodiment 1, as shown in fig. 6, as a preferred embodiment of the present invention, the end of the flow stabilizing tube 53 is fixedly provided with a flow meter 7, the flow meter 7 is used for detecting the flow rate of the water flowing through the flow stabilizing tube 53, when the flow rate is lower than a preset value a, it is predicted that the through holes 59 in the flow stabilizing tube 53 are mostly blocked, at this time, the flow meter 7 gives an alarm to prompt a worker to stop the operation of the drainage pump station, and clean the through holes 59 on the flow stabilizing tube 53 or replace the flow stabilizing tube 53.
Example 9 As a preferred embodiment of the present invention, on the basis of the above example 1, as shown in FIG. 1, the diameter of the steady flow pipe 53 is between 1.25m and 1.5 m;
taking the length of the water inlet tank 3 as 10m as an example, the partition pier 4 equally divides the water inlet tank 3 into four areas, each area has the length of 2.5m, and the diameter of the flow stabilizing pipe 53 is preferably 50% -60% of the length of the water inlet tank 3 because the flow stabilizing pipe 53 is used for preventing bad flow states such as backflow and vortex from being generated after water flows enter the front tank 2, so that the efficient operation of the flow stabilizing pipe 53 can be met, the blocking effect on the water flows can not be caused, and the subsequent operation of the first water wheel 55 and the second water wheel 62 can be influenced. The diameter d of the stabilizing tube 53 should be chosen to be
d 1 ＝D×0.5＝2.5×0.5＝1.25m
d 2 ＝D×0.6＝2.5×0.6＝1.5m
The diameter of the stabilizing tube 53 should be between 1.25m and 1.5 m.
Example 10 based on the above example 1, as shown in FIG. 1, the rotation speed of the steady flow tube 53 is between 0.21rad/s and 0.26rad/s as a preferred example of the present invention;
taking the flow rate of water flow in the drainage pump station as 4m/s as an example, since the flow rate of water flow is 4m/s and is generally calculated according to standard loss of a model, the rotation speed of the water wheel is 3m/s, the rotation speed of the first bevel gear 63 is 3m/s, and since the transmission ratio of the bevel gear of the structure is 2:3, the rotation speed of the second bevel gear 64 is
So the rotation speed of the cone gear 64 driving the flow stabilizing tube 53 to rotate is 2m/s, and the rotation speed of the flow stabilizing tube 53 is 2m/s because the diameter of the flow stabilizing tube 53 is 1.25m-1.5m
The rotation speed of the steady tube 53 is between 0.21rad/s and 0.26rad/s.
During operation, water flow enters the front pool 2 through the water inlet 1, the water level gauge 12 is used for monitoring the water level of the rectifying structure of the drainage pump station, the water flow enters the water inlet pool 3 after flowing through the front pool 2, in the water inlet pool 3, the water flow drives the first water wheel 55 and the second water wheel 62 to rotate, the first water wheel 55 drives the first bevel gear 63 to rotate, the first bevel gear 63 drives the second bevel gear 64 to rotate, and the second bevel gear 64 drives the flow stabilizing pipe 53 to rotate; the second water wheel 62 is matched with a generator in a rotating mode to convert kinetic energy into electric energy, the generator is used for supplying power to the water pump 58, after the water pump 58 works, the flow speed of water in the flow stabilizing pipe 53 is increased, the pressure in the flow stabilizing pipe 53 is reduced, the pressure outside the flow stabilizing pipe 53 is increased, water outside the flow stabilizing pipe 53 flows into the pipe under the action of pressure difference, so that the water outside the flow stabilizing pipe 53 changes in direction, and water flows to the direction through holes 59 of the flow stabilizing pipe 53 under the action of pressure difference, and vortex and backflow are prevented from being generated in the front pool 2 and the water inlet pool 3; because the flow stabilizing pipe 53 only has through holes 59 on two sides, bevel gear transmission is needed to drive the flow stabilizing pipe 53 to rotate so as to prevent vortex and reflux in the up-down direction of the flow stabilizing pipe 53; the flowmeter 7 is arranged at the tail end of the flow stabilizing pipe 53, the flowmeter 7 detects the flow in the flow stabilizing pipe 53 in real time, when the flow is lower than a preset value A, the flow meter 7 gives an alarm at the moment, prompts a worker to stop the work of a drainage pump station, and cleans the through hole 59 on the flow stabilizing pipe 53 or replaces the flow stabilizing pipe 53, wherein the through hole 59 in the flow stabilizing pipe 53 is predicted to be mostly blocked.
