Background
With the increasing exhaustion of non-renewable energy sources, the traditional power generation mode cannot adapt to the long-term development of society. In order to reduce the dependence on non-renewable energy such as coal, the state advocates the development and utilization of new energy, wherein the development of hydraulic energy mostly utilizes dams to generate electricity, the large-scale hydraulic power generation equipment not only has certain requirements on geographical positions, but also has complex matching structures, and needs to consume a large amount of manpower and financial resources to construct some building structures, increase the water level difference and improve the potential energy of water, thereby improving the power generation efficiency and the total power generation amount. The construction process will undoubtedly cause damage to the environment and the cost is extremely high.
Meanwhile, China is a country with numerous rivers, and small-sized hydroelectric power generation equipment can be mostly carried out in rivers and lakes, but the power generation efficiency and the power generation amount of the large-sized small-sized hydroelectric power generation equipment are low. For example:

As shown in fig. 1, the power generation device includes a hollow housing, the housing has a circular or conical head, the head is pulled by a pulling rope, the tail is provided with a propeller blade, the housing is provided with a power generator, the propeller blade rotates, and energy conversion is performed by the power generator. However, the flat blade structure of the floating power generator cannot effectively increase the rotation speed of the generator shaft, and the generator shaft is rotated in a direction determined by the direction of the water flow, so that the floating power generator can be applied to only a river having a single flow direction. Meanwhile, the ellipsoidal shell can cause the instability of the power generation equipment, and the service life of the equipment is easy to shorten.
The Chinese invention patent (CN104653388A) provides a floating waterwheel power generation device. As shown in fig. 2, the floating waterwheel power generation device 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. However, the waterwheel power generation device is relatively complex in overall structure, and the force bearing area of the blades is relatively small, so that the power generation efficiency is relatively low. Meanwhile, the turning direction of the waterwheel is determined by the direction of the water flow, so that the waterwheel can be applied to rivers with a single flow direction.
Chinese invention patent (CN206429344U) provides a floating hydroelectric power generating device. As shown in fig. 3, the structure of the floating anchor rod is that a roller impeller is arranged in a support, blades are arranged on the roller impeller, shafts are arranged at two ends of the roller impeller and fixed on a bearing seat, the shaft at one end of the roller impeller is connected with an input shaft of a gearbox through the bearing seat, a belt wheel is arranged on an output shaft of the gearbox and connected with the belt wheel of a generator through a belt, the bearing seat is fixed on the support, the support is fixed on a floating block, fixing devices are arranged at two ends of the support, and the fixing devices are sleeved on an anchor rod. However, the overall structure of the hydroelectric power generation device is complex, and inevitable loss exists in the process that the rotating shaft drives the generator to generate electricity through the belt. Meanwhile, the direction of the water wheel is determined by the direction of the water flow, so that the water wheel can be only applied to rivers with a single flow direction.
It is thus understood that none of the above patent technologies solves the problems of fixing the rotation direction of the turbine and reducing the resistance of the turbine.

Detailed Description
Before describing the present invention of a turbine with rotatable blades and a hydroelectric power plant having the same, two common terms, "bearing" and "turbine" are introduced. Wherein,
the bearing is an important part in the modern mechanical equipment. Its main function is to support the mechanical rotator, reduce the friction coefficient in its motion process and ensure its rotation precision.
The turbine is a rotary power machine which converts the energy of a flowing working medium into mechanical work. It is one of the main components of aircraft engines, gas turbines, steam turbines, generators, etc.
Fig. 4 shows a schematic view of the structure of a turbine with rotatable blades according to the invention. As shown in fig. 4, the turbine with rotatable blades of the present invention includes a main shaft 7. A plurality of blades 4 are uniformly arranged on the main shaft 7. Preferably, four blades 4 are uniformly arranged on the main shaft 7.
More preferably, the blades 4 are rectangular, square or triangular in shape, with an arc. That is, the paddle 4 is made of a plate material bent in an arc shape in a rectangular, square, or triangular shape. This shape makes it easier for the blades 4 to be impacted by the water flow and thus to bring the main shaft 7 into rotation.
Each of the blades 4 is connected to the main shaft 7 via a link shaft 5, so that the blade 4 can rotate about the link shaft 5 relative to the main shaft 7.
A plurality of barrier panels 6 are also fixedly connected to the main shaft 7. The plurality of barrier panels 6 are respectively located on one side of the interface of the blade 4 and the main shaft 7. Preferably, four blocking panels 6 are fixedly connected to the main shaft 7. One side of the boundary of each blade 4 and the main shaft 7 is provided with one blocking panel 6. In this way, the blocking panel 6 can block the rotation of the paddle 4, so that the paddle 4 can only rotate between 0 and 90 degrees relative to the main shaft 7.
The water flow impacts the blades 4, so that the main shaft 7 is driven to rotate, and power generation is realized.
More preferably, the connection head 9 of the spindle 7 is provided with a groove and a protrusion for connection.
Fig. 6 shows a schematic view of the structure of a hydroelectric power plant according to the invention. Figure 6 shows a schematic front view of a hydropower device according to the invention. As shown in fig. 6 and 7, the hydroelectric power generating apparatus of the present invention comprises a generator 1, a floating panel 3, and a turbine in which the above-described blades are rotatable. The hydropower device is allowed to float on the water surface by means of the floating panels 3. The generator 1 makes it possible to generate electricity. The turbine can drive the generator 1 to rotate so as to generate electricity.
Wherein the generator 1 is fixedly connected with one side of the floating panel 3. Preferably, the generator 1 is fixedly connected to one side of the floating panel 3 by a plurality of L-shaped connection plates 8. This allows the generator 1 to be more firmly fixed on one side of the floating panel 3.
The turbine is located on the other side of the floating panel 3. Wherein the main shaft 7 of the turbine is rotationally connected with the floating panel 3 by means of a bearing 2. And, the main shaft 7 is connected to a rotation shaft of the generator 1. In this way, the turbine is made to rotate relative to the floating panel 3 and is able to bring the generator 1 to generate electricity.
Preferably, the main shaft 7 is connected with the rotating shaft of the generator 1 through a convex-concave groove. For example, a convex-concave groove matched with the convex-concave groove of the connector 9 of the main shaft 7 is arranged on the rotating shaft connector 10 of the generator 1, so that the main shaft 7 is connected with the rotating shaft of the generator 1 through the convex-concave groove.
As shown in fig. 5, the dynamic process of the turbine in operation is analyzed. If the water flow direction flows from right to left, because the blocking panel 7 behind the lower blade 4 has the supporting force effect on the lower blade 4, the water flow can be over against and impact the lower blade 4, the contact area is large, the acting force of the borne water flow can be larger, and the force borne by the lower blade 4 is taken as power, so that the turbine rotates anticlockwise.
For the upper blade 4, because the blocking panel 7 is on the other side of the upper blade 4, the upper blade 4 rotates to the left under the action of the water flow, so that the action of the water flow on the upper blade 4 is small, that is, the resistance is small, and the spindle 7 rotates counterclockwise due to the inequality of the action of the water flow on the two blades 4.
The flow in the other direction is the same as in the above case and will not be described in detail here.
Therefore, the main shaft 7 rotates only in one direction, and the resistance to rotation is small, so that the generator can generate power continuously in one direction, and the efficiency is high.
The hydroelectric power generation equipment is designed on the basis of the traditional turbine, and the blades can only move between 0-90 degrees by linking the rotating shaft, the blocking panel and other parts, so that the contact surface of resistance can be reduced, and the resistance of the turbine in water rotation can be greatly reduced; meanwhile, the turbine is vertically placed in water, and as the power in each direction is unchanged, the resistance is reduced, the difference between the power and the resistance is increased, and the turbine rotates along the power direction and cannot change along with the change of the water flow direction.
The above examples of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. Not all embodiments are exhaustive. All obvious changes and modifications which are obvious to the technical scheme of the invention are covered by the protection scope of the invention.
