Background

The hydro-electric power generation system (hydro-electric power) utilizes the potential energy of water flowing from high places such as rivers and lakes to low places, converts the potential energy contained in the water flowing into the kinetic energy of a water turbine, and then uses the water turbine as motive power to drive a generator to generate electric energy. The hydraulic machine (water turbine) is pushed to rotate by utilizing water power (with a water head), the water power is converted into mechanical energy, if another machine (generator) is connected to the water turbine and rotates along with the water turbine, electricity can be generated, and the mechanical energy is converted into electric energy. Hydroelectric power generation is in a sense the process of converting the potential energy of water into mechanical energy and then into electrical energy. Therefore, the prior art mainly utilizes the gravitational potential energy of water to convert into mechanical energy to generate electricity.

Although the device can realize floating type power generation, the device needs to establish structures such as foundation piles, water retaining plates, gates and the like in a river channel, the construction cost is high, and meanwhile, the natural environment can be damaged.

For example, the invention patent with application number 201310599316.2 discloses a floating waterwheel power generation device, which consists of waterwheel wheels, a water flow push plate, a bearing, a gear transmission, a generator, a waterwheel floating tank, a floating tank bracket, a waterwheel fixing buckle, a flow combining plate and a fixing column, wherein (1) the waterwheel wheels are uniformly provided with the water flow push plate; (2) the axle center of the waterwheel wheel is provided with a bearing which is connected with the water flow push plate; (3) a gear transmission and a generator are respectively arranged on two sides of the bearing; (4) two sides of the waterwheel wheel are respectively provided with a waterwheel floating tank, and the waterwheel floating tanks and the waterwheel wheel are connected and fixed by adopting a floating tank bracket; (5) the front and the rear positions of the waterwheel floating tank are provided with waterwheel fixing buckles; (6) two groups of floating waterwheel power generation devices are arranged in a river and are connected in series; (7) a current combining plate is arranged between the two groups of floating waterwheel power generation devices; (8) four fixing columns are arranged on two banks of a river and are arranged in parallel and are rectangular; (9) connecting the four fixing columns by using two steel wires, and connecting the fixing column at one end of the river to the fixing column at the other end of the opposite bank; (10) the waterwheel fixing buckle is arranged between the two steel wires.

In the prior art, a river channel is provided with a plurality of sections of blades, the width of each section of blade occupies a very small part of the width of the river channel, and when the flow rate of water flow in the river channel is relatively low, the width of the blade is narrow, so that the blades cannot be driven to rotate, and a generator set cannot normally operate to generate electricity. According to the invention, the transverse shaft is fixed by the floating boxes floating in the river channel, the blade drum is driven to rotate by the blades fully distributed in the river channel (namely crossing the river channel), the blades can be impacted by the flow of water flow in the whole river channel, so that one generator set connected with the blade drum is driven to generate electricity, on one hand, the blades are impacted by the whole water flow between the two floating boxes, so that the blades can be driven to rotate when the flow rate of the water flow is slow, and the generator set can be driven to rotate to generate electricity; on the other hand, the floating box, the cross shaft, the blade roller and the blades form a blocking effect on the river channel, so that water flow in the river channel can be concentrated on the blades, impact force on the blades is improved (the rotating speed of the blades is improved), and the generating capacity is further improved. And prior art sets up the mode of multistage blade, under the effect of blockking of multistage blade, can guide rivers to flow away from between the adjacent blade to lead to generating set's generated energy greatly reduced.

The structural design of the cross shaft is formed by connecting a plurality of sections of cylindrical components and connecting components between adjacent cylindrical components, the cylindrical sleeve is arranged on the periphery of each cylindrical component, the fixing ring fixedly connected with the cylindrical sleeve is arranged in the middle of the cylindrical sleeve, so that the blade rollers are arranged on the cross shaft at intervals along with the cylindrical components, the adjacent blade rollers form a whole through the second connecting rod, and then the blades are arranged on the blade rollers and cross the river channel, so that the stress of the blades and the cross shaft crossing the river channel is more uniform, the stability of the blades and the cross shaft is improved, and the blades and the cross shaft are prevented from being bent due to the nonuniform stress.
