The invention is described in further detail below with reference to the following detailed description and accompanying drawings:

referring to fig. 1, 2 and 3, in the present embodiment, a drainage device includes a body 2 with a water passing cavity 6 therein, a fan blade 3 rotatably disposed on the body 2 and located in the water passing cavity 6, an upper cover 1 for covering the water passing cavity 6, and a motor assembly for driving the fan blade 3 to rotate. The body 2 is provided with a water inlet 4 and a water outlet 5 which are respectively communicated with the water passing cavity 6, the fan blades 3 are provided with a plurality of blades, the upper cover 1 is provided with a pressure release hole 8 which is communicated with the water passing cavity 6 and the outside, and the pressure release hole 8 corresponds to the water passing cavity 6 and is clamped in the area between the water inlet 4 and the water outlet 5.

Specifically, the water passing cavity 6 can be divided into three relatively independent water containing areas by the three blades, when the fan blades 3 are driven by the motor assembly to rotate to work, the water containing area facing the water inlet 4 can store water, when the water containing area rotates to the pressure release hole 8 area of the upper cover 1, the water containing area is subjected to pressure release, and then when the water containing area continues to rotate and faces the water outlet 5, water in the water containing area is discharged from the water outlet 5 under the action of inertia and water pressure.

As shown in fig. 3 and 4, the fan blade 3 is provided with three uniformly distributed blades, the water passing cavity 6 is a cylindrical cavity, and the three blades divide the water passing cavity 6 into A, B, C three water containing areas. In addition, the water inlet 4 and the water outlet 5 are oppositely arranged on the body 2, and the pressure relief hole 8 is positioned on the perpendicular bisector of the water inlet 4 and the water outlet 5.

As shown in fig. 4, 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 4 at this time.

When fan blade 3 rotates counterclockwise to reach the position shown in fig. P2, water-containing area a faces water inlet 4, and water enters from water inlet 4 and fills water-containing area a.

When fan blade 3 further rotates counterclockwise to reach the position shown in fig. P3, pressure release hole 8 releases 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 8 can well relieve the pressure of the water containing area A.

When fan blade 3 further rotates counterclockwise to reach the position shown in fig. P4, water containing area a is opposite to water outlet 5, and water in water containing area a is rapidly discharged from water outlet 5 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 3 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 5 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.

As shown in fig. 2, in the present embodiment, the pressure release hole 8 is a fan-shaped through hole that penetrates the upper cover 1 vertically. In addition, in this case, two ends of the rotating shaft of the fan blade 3 respectively extend outwards and are respectively rotatably disposed on the main body 2 and the upper cover 1.

As shown in fig. 5, in the present embodiment, the end sections of the three blades are each provided with a water chute 7. In the scheme, the water chute 7 is U-shaped and winds from the upper surface of the blade, the tail end of the blade and the lower surface of the blade. In the working process of the fan blades 3, the water guide groove 7 helps to reduce the blocking effect of the rotating fan blades 3 on the water inlet 4, and water can conveniently flow into the water passing cavity 6 from the water inlet 4. Meanwhile, in the scheme, the gap between the blade and the side wall of the water passing cavity 6 can be 5-15 mm, the gap can not interfere with the body 2 in the long-term work of the blade, and meanwhile, the gap also ensures that the water containing area A, B, C is relatively independent.

Fig. 6 and 7 show a schematic view of an entrance and exit ramp of an underground garage, wherein the drainage system of fig. 7 is arranged below the ramp. The slope is provided with an air-wall water blocking device 9 and a rainwater grate 10 for draining water, wherein the air-wall water blocking device 9 is a device which can spray air flow and generate an air wall in front to change the flow direction of rainwater, a track S1 in the figure is a track of rainwater flowing through the slope when the air-wall water blocking device 9 does not work, and a track S2 is a track of rainwater finally flowing into the rainwater grate 10 when the air-wall water blocking device 9 works. The air-wall water-blocking device 9 may be composed of components such as a fan, and will not be described in detail herein.

As shown in fig. 7, the rainwater flowing into the rainwater grate 10 flows into the water collecting tank 15, and then flows into the water storage tank 14 from the water collecting tank 15 in two paths, and the two paths of pipelines are respectively provided with the drainage devices, namely the first drainage device 12 and the second drainage device 13. In addition, it should be noted that the drainage system is equipped with a pressure supply assembly 11, and the pressure supply assembly 11 can drive water from the water collection tank 15 to flow into the water storage tank 14. The pressure supply assembly 11 may be an air supply device that provides a back pressure to the pipeline to allow water to flow continuously. In addition, the pipeline of the drainage system can be provided with valve bodies such as a one-way valve, a safety valve and the like to ensure the normal and safe operation of the drainage system, and the detailed description is omitted.

Through the above scheme of this embodiment, the drainage device of present case can greatly increased the water flow rate of pipeline in the drainage system, improves the efficiency of drainage.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
