Embodiment 1

[0039] Embodiment 1: as figure 1As shown, in the river 2 between the banks 1, four vertical upright columns 4a are fixedly installed at the bottom of the river, and horizontal bars 4b are respectively connected between the two upright columns 4a along the flow direction of the river 2 , the crossbar 4b is parallel to the water surface of the river 2, and the enclosure of the water turbine 5 is fixedly connected between the crossbars 4b. The enclosure is a cylindrical shape with openings at both ends and a grid-like periphery. The axial direction of is consistent with the flow direction of river 2. The crossbar 4b and the upright post 4a are loosely fitted and movably connected, and the water turbine 5 can move up and down along the upright post 4a along with the crossbar 4b to adapt to changes in different water levels of the river 2 . Column 4a, crossbar 4b, and the fixed rod connected between the columns 4a in the width direction of the river 2 and fixedly connected with th...

Embodiment 2

[0041] Embodiment 2: basic structure is as embodiment 1, wherein the shroud of water turbine is changed into as figure 2 The funnel type shown can further save material and cost.

Embodiment 3

[0042] Embodiment 3: as image 3 As shown, the three columns 4a of the support 4 are fixedly installed on the river bottom of the river 2, and a water turbine 5 is arranged between two adjacent columns 4a successively. The axially arranged blades form an impeller, and the radial direction of the impeller is consistent with the flow direction of the river 2 .

[0043] The water turbine rotating shaft 5a passes through the column 4a, and is movably connected with the column 4a through a bearing, and one end thereof is rotatably connected with the generator rotating shaft 3a of the generator 3 arranged on the river bank 1 through a gear, or may be rotatably connected with the generator rotating shaft 3a through a pulley .

Abstract

The invention relates to a hydropower generation system without dam, belonging to a power generation system, solving problems that at present the water power of rivers and lakes where it is not suitable for installing generators can not be used and if rivers are retarded to construct dams there are large power generation cost and long constructing period. Hydraulic turbines, which can rotate under the attack of water flow, can be set on rivers or falls and the rotary shaft of hydraulic turbine is connected with the rotary shaft of power generator actively by mechanical transmission method. Or a drainage device (closed drainage slot or pipe) extending to the downstream end along the flow direction is opened on the upstream end of rivers or falls with fall directly and the hydraulic turbine and generator integrated power generation device is set at the output position of drainage device. According to the demand, multiple hydraulic turbines are set in width and length directions of rivers in parallel or the drainage device constituted by multiple drainage pipes is set to form array generating set so as to improve the output power of generator and utilize energy sources more efficiently. It can be applied in various flowing rivers with fall.

Description

technical field [0001] The invention belongs to a power generation system, in particular to a dam-free water power generation system suitable for generating power by utilizing natural water flow. Background technique [0002] In the process of the rapid development of our country's economy, the energy problem has become an important issue whether our country's economy can maintain sustainable development. Therefore, the development and utilization of multiple energy sources is becoming more and more important now that fuel energy is increasingly scarce. [0003] Among the tens of thousands of kilometers of rivers and lakes in our country, the length that can block rivers and dams to install hydroelectric generators to generate electricity is less than 1% of the total length of rivers and lakes, which means that more than 99% of rivers and lakes cannot Realize building dams and installing generators to generate electricity. [0004] Moreover, the traditional damming of rive...
