Description

Technical Field

[0001] This utility model relates to the field of hydropower generation equipment technology, specifically to a floating hydropower generator set. Background Technology

[0002] A floating hydroelectric generator set is a device that uses the power of water flow to generate electricity. It typically consists of three main parts: a float, a turbine, and a generator. The float keeps the entire generator set afloat on the water surface and is stably anchored in the water using anchor chains or other securing devices to ensure its position in the water flow. The turbine uses the kinetic energy of the water flow to drive its blades, converting kinetic energy into mechanical energy. The generator is responsible for converting the mechanical energy generated by the turbine into electrical energy, thus outputting electricity.

[0003] In existing technologies, the design of the floating body of floating hydro-turbine generator sets often adopts a single box structure. Although this structure is simple, it lacks sufficient adaptive adjustment capability when facing water level fluctuations and wave impacts. Due to the continuous changes in water level and the irregular impact of waves, the floating body of a single box structure is difficult to maintain stability, which directly affects the stability and power generation efficiency of the entire generator set. Therefore, we propose a floating hydro-turbine generator set. Utility Model Content

[0004] The purpose of this invention is to address the common problem that floating turbine generator sets often employ a single-box structure for their floating body design. While simple, this structure lacks sufficient adaptive adjustment capabilities in the face of water level fluctuations and wave impacts. Due to the continuous changes in water level and the irregular impact of waves, the floating body of a single-box structure is difficult to maintain stability, which directly affects the stability and power generation efficiency of the entire generator set. This invention provides a floating turbine generator set.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A floating hydro-turbine generator set includes a central float. Connecting beams are fixedly connected to the upper end of the central float at both ends. Extended floats are fixedly connected to both sides of the two connecting beams. The extended floats on both sides are arranged parallel to the central float. Both the central float and the extended floats are shuttle-shaped floats. A speed-increasing generator is fixedly installed at the center of the central float. A speed-increasing gearbox is installed at the bottom of the speed-increasing generator. The output shaft of the speed-increasing gearbox is fixedly connected to the drive shaft of the speed-increasing generator. Drive shafts are fixedly connected to the input shafts of the speed-increasing gearbox on both sides. The outer ends of the drive shafts are rotatably mounted to the sidewalls of the corresponding extended floats via bearings. Multiple horizontal shaft turbines are keyed at equal intervals along the middle of the outer walls of the drive shafts on both sides.

[0007] Furthermore, a protective fixing rod is fixedly connected to the upper front side of the central float, and a central column is fixedly connected to the lower front end of the protective fixing rod. Multiple protective baffles are vertically installed at equal intervals on both sides of the central column.

[0008] Furthermore, the protective barrier is an arc-shaped rod structure, and the outer wall of the protective barrier is wrapped with a polytetrafluoroethylene bushing.

[0009] Furthermore, when the central float and the extended float are formed, a reinforcing inner mesh is embedded inside, and the reinforcing inner mesh is a square grid frame structure.

[0010] Furthermore, a fixing screw is welded and fixed at the upper center of the reinforced inner embedded mesh, corresponding to the mounting hole position of the connecting beam and the protective fixing rod. The upper end of the fixing screw passes through the connecting beam and the protective fixing rod at the corresponding position and is threaded with a fixing nut.

[0011] Furthermore, both ends of the connecting beam are provided with anchoring holes, and anchoring ropes are fixedly connected in the anchoring holes.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model improves the buoyancy of the entire device by setting a central float and an extended float, which are connected by a connecting beam to form a load extension. The shuttle-shaped structure design not only reduces water flow resistance but also enhances the stability of the device. When facing water level fluctuations and wave impacts, the shuttle-shaped float can better adapt to water flow changes, reducing the impact on the device and ensuring the stable operation of the generator set. When the tip of the shuttle-shaped structure faces the water flow, the water flow can be guided and collected by the tips of the central float and the extended float, increasing the water flow impact force and improving the power generation effect. In addition, the speed-increasing generator, as the core component of the generator set, is closely connected to the turbine through the speed-increasing gearbox, realizing the efficient conversion of mechanical energy into electrical energy. It has the advantages of structural stability and high power generation efficiency, enabling it to maintain efficient and stable operation even in complex aquatic environments. The modular structure facilitates installation and disassembly, maintenance and replacement, providing great convenience for practical applications.

[0014] 2. This utility model features a protective fixing rod. The protective fixing rod is fixed to two rows of protective baffles on both sides of the central float via a central column. The protective baffles are oriented towards the water flow, which can push away floating objects carried by the water flow, prevent floating objects from entering between the central float and the extended float, reduce the impact of floating objects, and prevent jamming of the horizontal shaft water turbine, thereby improving the operating efficiency and safety of the generator set.

[0015] 3. This utility model, through the installation of a reinforced inner net, can improve the structural strength of the central float and the extended float, enhance the overall load-bearing capacity and resistance to deformation, and enable it to remain stable when facing water level fluctuations and wave impacts, thereby ensuring the stability and power generation efficiency of the generator set.

When the tip of the shuttle-shaped structure faces the water flow, the water flow can be guided and collected by the tips of the central float 1 and extended float 2, increasing the water flow impact force and improving power generation efficiency. Furthermore, the speed-increasing generator 6, as the core component of the generator set, is tightly connected to the turbine section through the speed-increasing gearbox 10, achieving efficient conversion of mechanical energy into electrical energy.
