Detailed Description of the Preferred Embodiment

[0015] To make the above objects, technical solutions, and beneficial effects more clear and definite, the following specifically describes the present invention with reference to the accompanying drawings.

[0016] As Figures 1-5 shown, the floating power generation system includes a vertical column 1, a cross arm 4, a connecting piece 7, a connecting bolt 8, a permanent magnet motor 13, a rotating shaft 12, and a floating wheel 15; A grounding plate 2 is provided at the bottom surface of the vertical column 1, and a grounding plate 2 bolt hole is penetrated through the top surface of the grounding plate 2. The vertical column 1 is installed on the river ground by inserting a grounding bolt 3 into the top surface of the grounding. The cross arm 4 is connected to the vertical column 1. The cross arm 4 is installed on the side surface of the vertical column 1 through a mounting plate 5 and a mounting bolt 6. Two mounting plates 5 are provided. One is connected to the vertical column 1, and the other is connected to the cross arm 4. Mounting plate 5 bolt holes are penetrated through the two mounting plates 5. After the mounting plate 5 bolt holes on the two mounting plates 5 coincide, a mounting bolt 6 is inserted for installation. The vertical column 1 and the cross arm 4 are detachably connected, which is convenient for transportation and installation; The connecting member 7 is arranged on the bottom surface of the cross arm 4. The chain 9 is installed at the connecting member 7 through the connecting bolt 8. There are two groups of connecting members 7 arranged on the bottom surface of the cross arm 4, and the chain 9 is installed at the two groups of connecting members 7. The chain 9 is composed of chain components 18. Connecting holes 19 are arranged at the top and bottom of the chain component 18. After the connecting holes 19 of the two chain components 18 coincide, a screw 20 is inserted for connection. The chain components 18 rotate at the position of the screw 20. Multiple chain components 18 form the chain 9. The connecting member 7 includes a top plate 27 and side plates 28. The top plate 27 is welded to the bottom surface of the cross arm 4. There are two side plates 28, and the two side plates 28 are arranged opposite to each other on the bottom surface of the top plate 27. A connecting bolt hole 29 is penetrated through the side surface of the side plate 28; when the chain 9 is installed with the connecting member 7, the chain component 18 at the top of the chain 9 is located between the two side plates 28, and the connecting hole 19 at the top of the chain component 18 coincides with the connecting bolt 8 holes on the side surfaces of the two side plates 28, and then the connecting bolt 8 is inserted and fixed to complete the installation of the chain 9; The permanent magnet motor 13 is located between the two chains 9. Rotating shafts 12 are arranged on both sides of the permanent magnet motor 13. The rotating shafts 12 are installed at the chain components 18 at the bottom of the chain 9. The rotating shafts 12 are installed through the connecting holes 19 at the bottom of the chain components 18 at the bottom of the chain 9. The rotating shafts 12 rotate around the connecting holes 19. The permanent magnet motor 13 is connected to the chain 9 through the rotating shafts 12. The floating wheels 15 are connected to the rotating shafts 12 on the left and right sides of the permanent magnet motor 13. Blade 14 is arranged on the outer shell surface of the permanent magnet motor 13. The cable 16 of the permanent magnet motor 13 extends from the permanent magnet motor 13 and from the chain 9 to the position of the column 1. A distribution box 17 is arranged inside the column 1. The cable 16 is electrically connected to the distribution box 17. The cable 16 on the chain 9 is fixed by a fixing cable to prevent the cable 16 from falling off; The floating wheel 15 is composed of an upper floating wheel 21 and a lower floating wheel 22. Insertion openings 23 are penetrated through the top surfaces of the upper floating wheel 21 and the lower floating wheel 22. A connecting column 24 is inserted into the insertion opening 23. The connecting column 24 is connected to the rotating shaft 12. An inner cavity body 26 is arranged inside the floating wheel 15. The inner cavity body 26 is separated by a partition plate 25. The inner cavity body 26 separated by the partition plate 26 in the floating wheel 15 is multiple independent chambers. The floating wheel 15 is made of plastic material and is light in texture. The setting of the floating wheel 15 can increase the buoyancy. The upper floating wheel 21, the lower floating wheel 22 and the connecting column 24 are integrally formed without gaps and are not easy to let water in to affect the buoyancy. The setting of the floating wheel 15 increases the buoyancy. The inner cavity bodies 26 in the floating wheel 15 are arranged at intervals, and the multiple inner cavity bodies 26 are not connected. When the floating wheel 15 is damaged, water flow will not flow into the entire inside of the floating wheel 15 to affect the buoyancy of the floating wheel 15. The setting of the floating wheel 15 can keep the permanent magnet motor 13 floating on the water surface. Chain floating wheels 11 are installed on the side surfaces of the chain components 18 of the chain 9 through side mounting shafts 10. The structure of the chain floating wheel 11 is the same as that of the floating wheel 15. The setting of the chain floating wheel 11 can increase the buoyancy when the chain 9 contacts the water, and can prevent multiple sections of the chain 9 from entering the water and affecting the water entry depth of the permanent magnet motor 13 and the blades.

[0017] When generating electricity using the floating power generation system, the column 1 is installed on the river bank, on the bank of the river channel. The height of the column 1 is calculated based on the difference between the high water period and the low water period of the water flow. The cross arm 4 and the column 1 are fixedly connected by installation bolts 6, which can be determined according to the width of the river bed and the distance between the water flow and the bank. The permanent magnet motor 13 used is a waterproof permanent magnet motor 13. A paddle 14 is installed on the outer shell of the permanent magnet motor 13. Under the folding of the chain 9 and the clamping of the two floating wheels 15 on the left and right, the permanent magnet motor 13 can float on the water surface. In addition, the permanent magnet motor 13 itself has a certain buoyancy, and the draft position of the permanent magnet motor 13 is adjusted to the water level. The paddle 14 on the permanent magnet motor 13 is rotated by the water flow to generate electric energy; if the river is wide and the water flow is large, a permanent magnet motor 13 with a large power can be configured; if the river is small and the water flow is small, a permanent magnet motor 13 with a small power can be configured; the chain 9 is installed in the connector 7 using connecting bolts 8. The length of the chain 9 is determined by the water level difference between the high water period and the low water period of the river and the water channel. The lowermost section is used to install the two floating wheels 15, and the permanent magnet motor 13 is installed between the two floating wheels 15. Under the joint support of the two floating wheels 15 and the chain 9, regardless of the size of the water flow, the paddle 14 of the permanent magnet motor 13 rotates under the impact of the water flow to generate electric energy and form an electric current, forming a complete floating water conservancy power generation system; After the installation of the power generation system is completed, the stability of the column 1 and the cross arm 4 should be checked to eliminate potential safety hazards. After the installation is stable, power generation can be carried out; the permanent magnet motor 13 uses a waterproof permanent magnet generator. The permanent magnet motor 13 is a through-shaft motor, also called a long-shaft motor. The installation of the permanent magnet motor 13 is to extend the two ends of the motor axis axially, and the shaft has its own thread. At the connection point, bolts are used to interlock with the rotating shaft 12. In order to better utilize the natural water flow, the permanent magnet motor 13 selects a generator with a pole logarithm greater than 20 and a speed less than 360; When using the floating power generation system to generate electricity in the water channel during the low water period, the water depth of the water channel is at least 0.9M, and the width of the water channel is at least 1.5M; the relationship between the water flow velocity and the power generation efficiency parameters, the water flow velocity is in m / s, and the power generation efficiency is in percentage %. The water flow velocity and the power generation efficiency are as follows: Under the condition that the water flow velocity is 0.8 m / s, the power generation efficiency of the power generation system is at least 51% of the power generation of a 5-kilowatt generator; under the condition that the water flow velocity is 1.1 m / s, the power generation efficiency of the power generation system is at least 64% of the power generation of a 5-kilowatt generator; under the condition that the water flow velocity is 1.5 m / s, the power generation efficiency of the power generation system is at least 75% of the power generation of a 5-kilowatt generator; under the condition that the water flow velocity is 1.8 m / s, the power generation efficiency of the power generation system is at least 87% of the power generation of a 5-kilowatt generator; under the condition that the water flow velocity is 2.3 m / s, the power generation efficiency of the power generation system is at least 100% of the power generation of a 5-kilowatt generator, and the floating power generation system can operate stably. On the premise that the water flow velocity is greater than 0.8 m / s, 30% of the overall height of the permanent magnet motor 13 together with the blade 14 sinks into the water, and the power generation efficiency of the power generation system is at least 51% of the power generation of a 5-kilowatt generator.
