It should be noted that the pressure provided by the pressure supply assembly 7 can enable the water flows in the first pipeline 11 and the second pipeline 12 to generate back pressure in the same direction, and the pressure supply assembly 7 is an air pump assembly. Of course, in other embodiments, the pressure supply assembly 7 may supply pressure to the second line 12, or to both the first line 11 and the second line 12.

As shown in fig. 1, the air outlet device 2 is a device that can generate an air wall by spraying air in front to change the direction of rainwater flow. In fig. 1, a trajectory S1 represents a trajectory of rainwater flowing down the slope 1 when the wind outlet device 2 is not in operation; the locus S2 is a locus diagram showing that the rainwater is guided into the rainwater grate 3 when the wind outlet device 2 is operated.

Specifically, as shown in fig. 2 and 3, when the outside rains, rainwater flowing down along the slope 1 is guided into the rainwater grate 3 and flows into the water collection tank 5 by the air outlet device 2. The drainage device located below the slope 1 can guide the rainwater from the water collecting tank 5 into the water storage tank 6 through the first pipeline 11 and the second pipeline 12 respectively when the pressure supply device works, and finally drain the rainwater from the water storage tank 6. Wherein the first and

second pipes

11 and 12 are respectively installed with the first and

second drainage assemblies

9 and 10 for increasing the water flow rate.

As shown in fig. 6 and 7, in the present embodiment, the drainage assembly includes a body 28 with a built-in water passing cavity 31, a fan 27 rotatably disposed on the body 28 and located in the water passing cavity 31, an upper cover 26 for covering the water passing cavity 31, and a motor assembly for driving the fan 27 to rotate. The body 28 is provided with a water inlet 30 and a water outlet 29 which are respectively communicated with a water passing cavity 31, the fan blades 27 are provided with a plurality of blades, the upper cover 26 is provided with a pressure relief hole 32 which is communicated with the water passing cavity 31 and the outside, and the pressure relief hole 32 corresponds to the water passing cavity 31 and is clamped in the area between the water inlet 30 and the water outlet 29.

Specifically, the plurality of blades can divide the water passing cavity 31 into a plurality of relatively independent water containing areas, when the fan blades 27 are driven by the motor assembly to rotate to work, the water containing area facing the water inlet 30 can store water, when the water containing area rotates to the area of the pressure release hole 32 of the upper cover 26, the water containing area is subjected to pressure release, and then when the water containing area continues to rotate and faces the water outlet 29, the water in the water containing area is discharged from the water outlet 29 under the action of inertia and water pressure.

As shown in fig. 6 and 7, the fan blade 27 is provided with three uniformly distributed blades, the water passing cavity 31 is a cylindrical cavity, and the three blades divide the water passing cavity 31 into A, B, C three water containing areas. In addition, the water inlet 30 and the water outlet 29 are oppositely arranged on the body 28, and the pressure relief hole 32 is positioned on the perpendicular bisector of the water inlet 30 and the water outlet 29.

As shown in fig. 7, the drainage device of the present invention is divided into four steps P1, P2, P3 and P4, and its specific operation principle is as follows:

in P1, water has not yet entered the water containing area a from the water inlet 30 at this time.

When blade 27 is rotated counterclockwise to the position shown in fig. P2, water-containing area a will be opposite to water inlet 30, and water will enter from water inlet 30 and fill water-containing area a.

When blade 27 is rotated further counterclockwise to the position shown in FIG. P3, pressure relief hole 32 relieves pressure to water containing area A. It should be noted that, since the A, B, C water-containing areas are relatively independent, when water enters the water-containing area a in a short time, negative pressure is generated in the water-containing area a, which is not favorable for drainage. The pressure relief hole 32 can well relieve the pressure of the water containing area A.

When fan blade 27 further rotates counterclockwise to reach the position shown in fig. P4, and water containing area a is opposite to water outlet 29, the water in water containing area a will be rapidly discharged from water outlet 29 under the action of inertia and water pressure.

In the above process, when the water in the water-containing area a finally reaches the position shown in fig. P4 driven by the fan blades 27 from the position shown in fig. P2, the kinetic energy of the water in the water-containing area a is increased, and the water is discharged from the water outlet 29 at a high speed. Note that, for convenience of description, the above steps are described only for the water-containing region a. In operation, the water-containing regions A, B, C are sequentially connected to allow the outlet to be in a continuous state.

The air storage assembly comprises an air storage box 18, an air inlet piece 21 which is arranged on the air storage box 18 and communicated with the cavity 19, and an air outlet piece 20 which is arranged on the air storage box 18 and communicated with the cavity 19, wherein the air outlet piece 20 is provided with an air outlet channel which is approximately horizontally arranged.

Specifically, the rotating fan assembly 15 can draw air from the air inlet member 21 and then eject the air from the air outlet member 20 toward a designated direction to form an air wall to guide rainwater into a designated position. The fan assembly 15 includes not only the fan 16, but also an end cover 17 behind the fan 16. The end cover 17 is a circular sheet-shaped geometric body sleeved on the output shaft 14, and the rotating end cover 17 can change a wind power track positioned in the cavity 19, so that air is sprayed out from the air outlet channel more intensively. Of course, the side of the end cap 17 adjacent to the fan blades 16 may be provided with a plurality of air guiding drum surfaces to push and cut air, thereby further enhancing the air wall generated by the fan blade assembly 15.
