Description

[Technical field]

[0001] The present invention relates to hydroelectric power generation technology, in particular technology that can realize highly efficient power generation with a small head and without the need for dam construction, and more specifically, to a highly efficient rotating disk type hydroelectric generator set. [Background technology]

[0002] As is well known, hydroelectric power generation is the green energy with the least pollution to the environment. However, traditional hydroelectric power generation has high requirements for hydrology, and due to the structural constraints of the water turbine, it is necessary to build a dam on the river channel and drive the rotation of the water turbine with the impact force generated by the water level difference between the upstream and downstream. This method requires strict control and repeated demonstration, because, firstly, it requires a large investment (e.g., the Three Gorges Dam Project), and secondly, it affects the underwater ecosystem, especially the migration and reproduction of fish, and hinders the balance of biodiversity and development. Although the river channels in most parts of China have a certain degree of flow velocity, the geographical conditions and flow rate do not meet the standards for the construction of hydroelectric power plants, and in some places, the construction of hydroelectric power plants is not allowed due to the requirements of environmental protection, which results in a large amount of water energy being wasted. Meanwhile, thermal power generation is a factor that causes air pollution. Therefore, Chinese Patent 2016100717954 discloses a new hydroelectric power generation device that can generate electricity by utilizing the water flow without the need to block the river channel with a structure to supplement the power supply. This patent solves the problem of the power source of the generator in hydroelectric power generation, but does not disclose how to solve technical issues such as improving power generation efficiency or the arrangement of the generator set. Summary of the Invention [Problem to be solved by the invention]

[0003] SUMMARY OF THE PRESENT EMBODIMENTS The present invention aims to solve the problem of low power generation efficiency of conventional rotary disk type hydro-driven generator sets by designing a highly efficient rotary disk type hydro-driven generator set. [Means for solving the problem]

[0004] The technical solution of the present invention is as follows: A highly efficient rotating disk type hydro-driven generator set comprising an embedded support structure base 1, a transmission 2 attached to the support structure base 1, an input shaft of the transmission 2 connected to a support column 3 rotated by hydro-driven power, one or more output shafts arranged at equal intervals connected to the transmission 2, and one generator 4 connected to each output shaft.

[0005] The generators 4 include horizontal generators and vertical generators.

[0006] The support structure base 1 is composed of a foundation and an annular support wall 5, on which support balls or support rollers 8 are attached to reduce the frictional resistance of the driving member 7, and the driving member 7 is connected at one end to a support column 3 and at the other end to a reversible water baffle plate 6.

[0007] The driving member 7 is a rod or disk structure, and a support cable 9 is further attached between the support column 2 and the driving member 7 .

[0008] The water baffle plate 6 is disposed in an annular water passage 10 and rotates by being pushed by the flow of water, and an isolation device 13 is provided between a water inlet 11 and a water outlet 12 of the annular water passage.

[0009] The isolation device 13 is a isolation wall that is higher than the water surface, or is composed of a number of isolation plates that are higher than the water surface.

[0010] The beneficial effects of the present invention are as follows: The present invention significantly improves power generation efficiency, and by increasing the input rotation speed of the generator using a transmission, it is possible to improve the stability of power generation and output efficiency.

[0011] The present invention is advantageous in improving the rotational balance of the support columns by arranging the output shafts at equal intervals.

[0012] The present invention does not require the construction of dams, makes full use of water resources, requires no power, and has no destructive impact on the environment.

[0013] This invention enables flexible construction of power plants with low investment, makes full use of large rivers while allowing each tributary to play its proper role, and furthermore makes it possible to realize hydroelectric power generation by modifying artificial waterways (troughs).

[0014] In the present invention, the speed of the water current is low, so that the fish passing through it are not damaged, and the fish can pass through the rotating gap of the water barrier plate or the bottom of the water in both the return flow and the downward flow. Even if the fish collide with the water barrier plate, the damage they receive is small. [Brief description of the drawings]

[0015] [Figure 1] FIG. 2 is a schematic front view of the structure of the present invention. [Diagram 2] FIG. 2 is a top view of FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] The invention will now be further described with reference to the accompanying drawings and examples.

[0017] Please refer to Figs. 1-2. The highly efficient rotating disk type water-driven generator set includes an embedded support structure base 1, on which a transmission 2 is attached. A normal speed-increasing gearbox may be adopted as the transmission 2. The input shaft of the transmission 2 is connected to a support column 3 that rotates by water drive, and the vertical spindle of the transmission rotates with the rotation of the support column. After speed-increasing and allocation by the transmission, the power is output through one or more, preferably two to four, horizontal (and / or vertical) output shafts. Each output shaft is connected to the input shaft of a corresponding generator 4 to drive the operation of the generator. As shown in Fig. 1, the generator 4 may be a horizontal generator or a vertical generator. The support structure base 1 is composed of a foundation and an annular support wall 5, and as shown in Fig. 2, a support ball or support roller 8 for reducing the friction resistance of the drive member 7 is attached on the annular support wall. The drive member 7 is connected at one end to the support column 3 and at the other end to a reversible water baffle plate 6. The driving member 7 may have a rod structure or a disk structure. A support cable 9 for reducing the pressure of the driving member 7 on the annular support wall 5 is further attached between the support column 2 and the driving member 7, thereby reducing the frictional resistance between them. The structure of the water baffle plate 6 is the same as that of the prior art. The water baffle plate 6 in this embodiment is disposed in the annular water channel 10 and rotates by being pushed by the flow of water, and the water baffle plates 6 can be linked to each other via a cable 14 as necessary. An isolation device 13 is provided between the water inlet 11 and the water outlet 12 of the annular water channel, and the water inlet and the water outlet must not cross, and a certain head is required between them. In a specific implementation, as shown in FIG. 2, the isolation device 13 may adopt an isolation wall structure higher than the water surface, or may be composed of multiple isolation plates higher than the water surface.

[0018] All parts that are not related to the present invention are the same as or can be realized by the prior art.
