[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment discloses a combined ecological unit.

[0025] The utility model provides Figure 1-3 A combined ecological unit shown includes a water inlet pipe 1, a plurality of first through holes are opened in the wall of the water inlet pipe 1, a first connecting pipe 2 is inserted into the inside of each first through hole, the lower end of each first connecting pipe 2 is fixedly connected to the second connecting pipe 3, the lower end of each second connecting pipe 3 is fixedly connected to the first water turbine 4, the lower end of each first water turbine 4 is fixedly connected to the third connecting pipe 5, the lower end of each third connecting pipe 5 is commonly fixedly connected to a water collecting cover 6, an acceleration mechanism is arranged inside the water collecting cover 6, the lower end of the water collecting cover 6 is fixedly connected to a Tesla valve 7, the lower end of the Tesla valve 7 is fixedly connected to a fourth connecting pipe 8, and the lower end of the fourth connecting pipe 8 is fixedly connected to a second water turbine 13.

[0026] The water passing through the first water turbine 4 can be collected by the water collecting cover 6 and then passed to the second water turbine 13 through acceleration by the acceleration mechanism. In this process, the water flow can be accelerated for a second time by the Tesla valve 7 .

[0027] In order to speed up the water flow, Figure 1-2 As shown, the acceleration mechanism includes two rotating rods 9, two gears 10 and a motor 11. The two rotating rods 9 are rotatably connected to the inside of the water collecting cover 6. The two gears 10 are fixedly sleeved on the rod walls of the corresponding rotating rods 9 respectively. The two gears 10 are meshed with each other. The motor 11 is fixedly connected to one side of the water collecting cover 6. One end of one of the rotating rods 9 passes through one side of the water collecting cover 6 and is fixedly connected to the output end of the motor 11.

[0028] The motor 11 is started to rotate the rotating rod 9 connected thereto, and then the two gears 10 are driven to rotate. The rotation of the gears 10 can accelerate the water flow.

[0029] In order to accelerate the water flow before entering the first turbine 4, Figure 1-2 As shown, the size of the upper end of each first connecting pipe 2 is larger than the size of the lower end.

[0030] Because the size of the upper end of each first connecting tube 2 is larger than that of the lower end, the water flow will be squeezed when flowing through the first connecting tube 2, thereby increasing the flow rate of the water flow.

[0031] In order to facilitate water discharge, Figure 1-2 As shown, the lower end of the second water turbine 13 is fixedly connected with a water outlet pipe 12 .

[0032] The water flow can be discharged by using the water outlet pipe 12.

[0033] In order to facilitate the disassembly and installation of the device, Figure 1-2 As shown, a plurality of second through holes are formed on the upper surface of the water collecting cover 6, and each third connecting pipe 5 is respectively inserted into the inside of a corresponding second through hole.

[0034] The plug-in prevention makes it convenient for workers to disassemble and assemble the device.

[0035] Finally, in order to further accelerate the water flow, Figure 1-2 As shown, the water collecting cover 6 is in an inverted cone shape.

[0036] Because the lower end of the water collecting cover 6 is in an inverted cone shape, the space at the lower end of the water collecting cover 6 is smaller than the space at the upper end, so the water flow can be squeezed and accelerated.

[0037] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
