The drainage power generation device and its application will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

As shown in FIG. 1 and FIG. 2 , the drainage power generation device of an embodiment includes: an outer casing 10 , a rotating water pipe 20 , a fixed plate 30 , a transmission device 40 and a generator 50 .

The outer casing 10 is used to fix the fixing plate 30 and may be of any structure. In this embodiment, the outer casing 10 is in the shape of a barrel, and the lower end is provided with a drain port 12 . In other embodiments, the outer casing 10 can also choose any shape that can fix the fixing plate 30 . In special cases, the outer casing 10 can be omitted directly, and the fixing plate 30 can be fixed on any fixed structure, such as a wall.

In this embodiment, the rotating water pipe 20 includes a water inlet pipe 22 and a connecting pipe 24 communicating with the water inlet pipe 22 . The water inlet pipe 22 is generally a straight pipe, and the connecting pipe 24 is an elbow. The joint between the connecting pipe 24 and the water inlet pipe 22 forms an included angle.

In this embodiment, the water inlet pipe 22 and the connecting pipe 24 are integrally formed. In other embodiments, the water inlet pipe 22 and the connecting pipe 24 can be prepared separately, and the water inlet pipe 22 and the connecting pipe 24 are connected by a waterproof rubber ring so that the joint is not leaking, and at the same time, the water inlet pipe 22 and the connecting pipe 24 are fixed together .

In this embodiment, the connecting pipe 24 is a spiral bent pipe. The degree of spiral is not limited, and can be one circle, one and a half circles, two circles, three circles, etc.

In other embodiments, the connecting pipe 24 may also be a broken-line bent pipe, an annular bent pipe, or the like.

The shape of the connecting pipe 24 does not affect the inner diameter and inner circumference of the connecting pipe 24, that is, the inner diameter and inner circumference of the connecting pipe 24 remain unchanged. In this embodiment, the connecting pipe 24 is a round pipe, and its outer and inner circumferences are both circular. In other embodiments, the inner or outer circumference of the connecting pipe 24 may also be in other shapes such as a square.

The water inlet 26 of the rotating water pipe 20 is located at the end of the water inlet pipe 22, the water outlet 28 is located at the end of the connecting pipe 24, and there is only one water inlet 26. In this embodiment, there is one connecting pipe 24 and one water outlet 28 . In other embodiments, there may be two or more connecting pipes 24, and there may be two or more water outlets 28.

As shown in FIG. 3 , the rotating water pipe 220 of another embodiment has the same basic structure as the rotating water pipe 20 , the difference is that the rotating water pipe 220 includes two connecting pipes 224 and has two water outlets 228 .

Returning to this embodiment, the water outlet direction of the water outlet 28 can generally be in any direction. Of course, those skilled in the art can understand that when the water outlet direction is upward, the efficiency is low. In this embodiment, the water outlet direction of the water outlet 28 is vertically downward.

As shown in Figure 4, the rotating water pipe 320 of another embodiment has the same basic structure as the rotating water pipe 20, the difference is that the connecting pipe 324 of the rotating water pipe 320 is in the shape of a broken line, and the water outlet direction of the water outlet 328 is the same as that of the rotating water pipe 320. direction of rotation is opposite. At this time, the recoil force formed after the water flow is discharged can be used to push the rotating water pipe 320 to rotate, so that the efficiency is higher.

As shown in FIG. 5 , the rotating water pipe 420 of another embodiment has the same basic structure as the rotating water pipe 320 , the difference is that the outer and inner peripheries of the water inlet pipe 422 and the connecting pipe 424 are both square.

As shown in Figure 6, the rotating water pipe 520 of another embodiment has the same basic structure as the rotating water pipe 20, and the connecting pipe 524 of the rotating water pipe 520 is also helical. The difference is that the spiral degree of the connecting pipe 524 is relatively low, and The water outlet direction of the water outlet 528 of the rotating water pipe 520 is opposite to the rotating direction of the rotating water pipe 520 .

The rotating water pipe 620 of another embodiment shown in Figure 7 has the same basic structure as the rotating water pipe 20, and the connecting pipe 624 of the rotating water pipe 620 is also helical. 620 also includes a water outlet pipe 629 , and both the water outlet pipe 629 and the water inlet pipe 622 are on the axis of the rotating water pipe 620 . When the rotating water pipe 620 of this embodiment is applied to a drainage power generation device, another fixed plate for supporting the water outlet pipe 629 can be provided in the horizontal direction of the water outlet pipe 629. On the fixed plate, at this time, since the water outlet pipe 629 and the water inlet pipe 622 are all on the axis of the rotating water pipe 620 and are supported by the fixed plate simultaneously, the stability of the whole drainage power generation device is better.

Returning to this embodiment, the fixing plate 30 is fixed on the outer casing 10 and is better fixed by the auxiliary fixing piece 32 .

One end of the water inlet pipe 22 of the rotating water pipe 20 passes through the fixing plate 30 , and one end of the water inlet pipe 22 of the rotating water pipe 20 is rotatably arranged on the fixing plate 30 . That is, the rotating water pipe 20 can rotate, and at the same time, the fixing plate 30 also supports the rotating water pipe 20 .

In this embodiment, one end of the water inlet pipe 22 of the rotating water pipe 20 is rotatably fixed on the fixing plate 30 through a rotating bearing 29 . In other embodiments, other types of rotating assemblies may also be used. In particular, it is also possible to directly expand the outer side of the water inlet pipe 22 and contact the fixed plate 30 without using the rotating assembly, and polish the contact between the expanded part of the outer side of the water inlet pipe 22 and the fixed plate 20, and apply lubricant. Alternatively, the active part 42 fixedly connected with the water inlet pipe 22 is used, the contact between the active part 42 and the fixed plate 30 is polished smooth, and lubricant is applied.

The transmission device 40 is respectively connected with the water inlet pipe 22 and the generator 50, and transmits the power generated by the rotation of the rotating water pipe 20 to the rotating shaft 52 of the generator 50, thereby driving the generator 50 to generate electricity.

In this embodiment, the transmission device 40 includes an active part 42 and a passive part 44 , the active part 42 is fixed on the outside of the water inlet pipe 22 , and the passive part 44 is fixed on the rotating shaft 52 of the generator 50 . As shown in FIG. 1 and FIG. 2 , both the driving part 42 and the transmission part 44 are bevel gears, and the driving part 42 and the transmission part 44 mesh. When the rotating water pipe 20 rotates, the driving member 42 also rotates, thereby driving the transmission member 44 to rotate, and when the transmission member 44 rotates, the rotating shaft 52 of the generator 50 also rotates, thereby driving the generator 50 to generate electricity.

The rotating water pipe 20 of this drainage power generation device rotates, and the driving part 42 and the transmission part 44 are both bevel gears and meshed so that the linear speed of the two is the same. When the outer diameter of the rotating water pipe 20 is larger, the driving part 42 is correspondingly larger. The driving element 42 obtains a larger torsion force, and the transmission element 44 rotates at a faster speed. For example, when the outer diameter of the driving member 42 is five times that of the transmission member 44 , the rotation speed of the transmission member 44 is also five times that of the driving member 42 .

In this embodiment, a spiral curved pipe is used as the connecting pipe 24 . It can be understood that, for the spiral curved pipe, the greater the degree of spiral, the greater the torque obtained by the active member 42 . Simultaneously, the larger the helical radius is, the larger the torsion force obtained by the driving member 42 is.

In other embodiments, the transmission device 40 may also include a transmission belt, which is respectively connected to the driving element 42 and the passive element 44, so as to perform power transmission over a relatively long distance. In addition, the transmission device 40 may also include a transmission chain, etc., and the transmission chain is respectively connected with the active element 42 and the passive element 44 to assist in completing the power transmission, and the details are not listed one by one.

This drainage power generation device can be applied to a variety of hydroelectric power generation sites, such as mountain springs, rivers, etc. The following will briefly introduce the application of the drainage power generation system to high-rise wastewater power generation as an example.

1 and 2, high-rise wastewater flows into the water inlet pipe 22 from the water inlet 26, then flows along the connecting pipe 24, and finally is discharged from the water outlet 28. During this process, the gravitational potential energy of the high-rise wastewater is converted into kinetic energy, and pushes the rotating water pipe 20 turns. When the rotating water pipe 20 rotates, the driving member 42 also rotates, thereby driving the transmission member 44 to rotate, and when the transmission member 44 rotates, the rotating shaft 52 of the generator 50 also rotates, thereby driving the generator 50 to generate electricity.

When this drainage power generation device is applied to high-rise wastewater power generation, the high-rise wastewater can be discharged into the water inlet pipe 22 through the sewage pipe, and the sewage pipe can be connected with the water inlet pipe 22 through a waterproof rubber ring, so that the connection between the sewage pipe and the water inlet pipe 22 can be rotated And no water leakage.

This kind of drainage power generation device has a simple structure. When it is applied to high-rise wastewater power generation, the gravitational potential energy of high-rise wastewater is converted into kinetic energy to drive the rotating water pipe 20 to rotate and at the same time transmit the power to the rotating shaft 52 of the generator 50 through the transmission device 40, thereby Drive the generator 50 to generate electricity. Compared with the traditional drainage power generation system that relies on the rotation of the impeller or turbine to drive the generator to generate electricity, this drainage power generation system is not easy to block.
