The time for building a power station is short, the investment recovery speed is fast, and the social and economic benefits are very significant.

[0004] To achieve the above object of the invention, the solution adopted by the present invention is a floating ball funnel type hydroelectric power generation device, including: a front funnel, a rear funnel, a water turbine, a generator and supporting components, a rear funnel water outlet hopper, a rear funnel water inlet hopper, pipe clamps, rear funnel pulling ropes, front funnel pulling ropes, a fence net, a diversion waterproof cloth, a flow velocity sensor electric winch, pipe clamps, a tail pipe, floating balls, an anchor pile frame, and a bottom foundation, etc.

[0005] The rear funnel of the present invention is composed of a conical diversion waterproof cloth (thin plate) water inlet funnel, a thin plate water outlet funnel, a water turbine, a generator and supporting components installed in the thin plate tail pipe, etc. The front funnel is a conical diversion waterproof cloth (thin plate) funnel. On the waterproof cloth (thin plate) of the rear funnel water inlet funnel, front and rear radial pipe clamps are provided; on the diversion waterproof cloth (thin plate) of the front funnel, front and rear radial pipe clamps are provided. Front and rear radial pipe clamps.

[0006] On the pipe clamp at the mouth edge of the rear funnel facing the large water inlet of the water flow, at least 3 and several rear funnel pulling ropes are evenly spaced. The other ends of the at least 3 and several rear funnel pulling ropes are tied together and fixedly connected to the pulling rope on the anchor pile frame upstream in the axial direction of the rear funnel; the front and rear radial pipe clamps adjacent to each other along the inclined plane of their respective diversion waterproof cloths in the axial direction of the two funnels are sleeved together with a loose joint, that is, the radial pipe clamp on the small water outlet of the front funnel is sleeved outside the radial pipe clamp on the large water inlet of the rear funnel; on the docking surface of the two pipe clamps, a thin waterproof layer is respectively painted, sprayed, or adhered; on the pipe clamp at the large water inlet of the front funnel facing the water flow, at least 3 and several front funnel pulling ropes are evenly spaced. The other ends of the at least 3 and several front funnel pulling ropes are tied together and connected to the pulling rope of the electric winch on the anchor pile frame upstream in the axial direction of the front funnel. The electric winch of the flow velocity sensor installed on the anchor pile frame is equipped with an automatic monitoring water flow velocity sensing device and can control the operation of the electric winch to adjust the length of the pulling rope on the electric winch back and forth, so as to drive the front funnel to move backward or forward. Under the impact of the water flow, the loose joint where the front and rear two funnels are sleeved with each other slowly opens backward or slowly closes forward, adjusting the water body in the front funnel to flow out or gather into the water inlet funnel of the rear funnel, which is a stepless adjustment mechanism for large and small fluctuations in water flow velocity, adjusting the water collection range and the amount of water flowing into the rear funnel, and is used to improve the relative stability of the power generation quality of the water turbine and the generator when the water flow velocity changes.

[0007] The diversion waterproof cloth of the present invention can be made of polyester, high-strength fiber base materials, aramid fiber, ultra-high molecular weight polyethylene, carbon fiber composite materials, glass fiber reinforced polymers, PVC double-sided coated mesh cloth, and Oxford cloth, etc., and can be subjected to waterproof enhancement treatments such as polyurethane coating, rubber layer, thermoplastic polyurethane coating, polytetrafluoroethylene lamination, graphene coating, etc. It can also be structurally optimized and adopt seamless joining technology, etc.

[0008] The diversion waterproof thin plate of the present invention can be made of metal thin plates such as aluminum alloy thin plates and stainless steel thin plates, or can also be made of non-metal thin plates such as plastics with high strength, carbon fiber, and high-performance composite materials.

[0009] The radial pipe clamp of the present invention is a hollow pipe and can be made of metal pipe materials such as carbon steel, stainless steel, and aluminum alloy, or can also be made of high-strength non-metal pipe materials such as plastics, carbon fiber, and high-performance composite materials.

[0010] The traction rope of the present invention can be made of stainless steel wire rope or synthetic fiber with high tensile strength, such as ultra-high molecular weight polyethylene material, etc.

[0011] In the present invention, the front and rear funnels are axially sleeved with each other in a loose-fitting manner to form a combination. The large mouth of the front funnel faces the water flow for water inlet, and the small mouth discharges water. The water flow entering the water inlet funnel and the water outlet funnel of the rear funnel flows out after being subjected to hydraulic, mechanical, and electrical conversions through the water turbine, generator, and supporting components in the tail pipe. The generated electricity is output through the transformer and circuit configured to match it.

[0012] In order for the floating ball funnel type hydroelectric power generation device of the present invention to always float under the set water surface and be in a normal power generation state, floating balls each equipped with a traction rope and floating on the water surface are respectively installed on the radial pipe clamp of the water inlet funnel of the rear funnel, the tail pipe, the large-diameter radial pipe clamp of the water inlet of the front funnel, and the top of the traction winch, etc.

[0013] There are various types of materials for manufacturing the floating balls of the present invention. Mainly, waterproof materials such as latex (natural rubber) aluminum foil, plastics, Oxford cloth, or high-strength, weather-resistant, and wear-resistant materials such as reinforced fiber and polyester can be used.

[0014] The anchor pile frame provided on the underwater foundation of the present invention can be a single anchor pile, or a combination of multiple anchor piles and brackets, or can also be one or multiple combined gravity anchor solids, such as combined anchor solids of anchor chains or heavy objects (concrete blocks, or steel reinforcement cages and concrete).

[0015] In order to protect the water turbine, generator, and supporting components, etc., a net for intercepting floating dirt is installed on the outer side of at least 3 or several traction ropes evenly spaced on the radial pipe clamp of the large water inlet of the front funnel facing the water flow.

[0016] In the present invention, a guide ring is arranged in a circle inside the small water outlet (throat) of the water outlet funnel of the rear funnel. The guide ring can convert part of the water flow in the rear funnel from axial water flow into tangential water flow consistent with the rotation direction of the water turbine. The structure of the guide ring is composed of at least one or several annular guide groove plates connected and combined into a circumferential guide ring, and the bottom plate of the guide groove plate is fixed on the thin plate inside the circle of the small water outlet of the water outlet funnel of the rear funnel. On each guide groove plate, one or several streamlined curved plates are evenly spaced. The one or several streamlined curved plates can guide the axial water flow into tangential water flow in the same direction as the rotation of the water wheel. The tangential water flow flowing out of the guide ring arranged in a circle inside the small water outlet (throat) of the water outlet funnel of the rear funnel flows into the tail pipe of the rear funnel.

[0017] In order to increase the water pressure and flow rate in the rear funnel and improve the hydroelectric power generation efficiency, a reverse inclined tail funnel pipe with a certain length is butt-jointed and matched at the outer end of the water outlet of the tail pipe of the rear funnel.

[0018] On the collar of the front funnel facing the large water inlet of the water flow, at least 3 and several front funnel towing ropes are evenly spaced. The other ends of at least 3 and several front funnel towing ropes are tied together and fixedly connected to the towing rope on the upstream anchor pile frame in the axial direction of the front funnel; the radial collars of the adjacent front and rear funnels along the inclined planes of their respective diversion waterproof cloths in the axial direction are sleeved together with a loose joint, that is, the radial collar on the small water outlet of the outer front funnel is sleeved with a loose joint on the radial collar of the large water inlet of the inner rear funnel; on the docking surfaces of the two collars, a thin waterproof layer is respectively painted, sprayed, or adhered; on the collar of the rear funnel facing the large water inlet of the water flow, at least 3 and several front funnel towing ropes are evenly spaced. The other ends of at least 3 and several rear funnel towing ropes are tied together and connected to the towing rope of the flow velocity sensor electric winch on the upstream anchor pile frame in the axial direction of the rear funnel. The flow velocity sensor electric winch installed on the anchor pile frame is equipped with an automatic monitoring water flow velocity sensing device and can control the operation of the electric winch to adjust the length of the towing rope on the electric winch back and forth, thereby driving the rear funnel to move forward or backward. Under the traction of the towing rope, the loose joint where the front and rear funnels are sleeved with each other slowly opens forward or closes backward slowly, adjusting the water body in the front funnel to flow out or collecting and entering the water inlet of the rear funnel, which is an infinitely variable adjustment mechanism for large and small fluctuations in water flow velocity, adjusting the water collection range and the amount of water flowing into the rear funnel, and is used to improve the relative stability of the power generation quality of the water turbine and generator when the water flow velocity changes.

[0019] In order to keep the device running normally and prevent upstream debris from affecting safety, a debris barrier net can be set upstream of the water body passage of the device and cleaned in time.

[0020] In order to adapt to ocean tide conditions, at an appropriate position perpendicular to the side of the funnel floating type hydraulic power generation device, an anchor post frame is provided, which is equipped with an automatic monitoring device for water flow direction and velocity and can control the operation of the electric winch to pull the towing rope connecting the device back and forth, adjusting the whole device to face the water flow in the positive and negative directions of the tide.

[0021] In order to form large-scale, modular and large-scale, at least one set and several sets of floating ball funnel type hydraulic power generation devices are combined in parallel to form a cluster.

[0022] In order to improve the working efficiency of the device, at least one and several sensors are configured to intelligently adjust and control at least one and several hydraulic generator systems to achieve a cluster, automatic, visual, efficient and unmanned operation mode.

[0023] Comprehensive creative description of the present invention: Before and after the funnels of the present invention can collect horizontal flowing water over a large area. Through the superposition of the contraction tube effect, the kinetic energy, pressure energy, and potential energy of the water flowing into the rear funnel are gradually increased in pressure. The speed of the horizontal flowing water can be increased several times, even more than ten times. This enables the water turbine and generator installed in the outlet tail pipe of the rear funnel to significantly enhance their ability to convert water energy into electricity. Not only is the cost significantly reduced, but the comprehensive cost performance is also very high. The present invention conducts new exploration in the field of horizontal flowing water power generation by applying the "water tunnel" type Venturi effect.

[0024] The present invention arranges a guide ring around the circumference of the small outlet (throat) of the outlet bucket of the rear funnel. The guide ring can convert part of the water flow in the rear funnel from axial water flow into tangential water flow in the same direction as the rotation direction of the water turbine, guiding the axial water flow into tangential water flow in the same direction as the rotation direction of the water turbine and flowing into the outlet tail pipe of the rear funnel. This increases the tangential force and rotational force in the water flow at the outlet of the small outlet (throat) of the outlet bucket of the rear funnel. The tangential kinetic energy has the ability to transfer and enhance. Driven directly by the tangential water flow, the water turbine can more effectively convert water energy into mechanical energy, and thus into more useful mechanical energy and electrical energy.

[0025] The electric control winch of the flow velocity sensor installed on the anchor post frame of the present invention is equipped with an automatic monitoring device for water flow velocity induction, and can control the operation of the electric winch. It is used to adjust the length of the pulling rope on the electric control winch back and forth, thereby driving the front funnel to move backward or forward. Under the impact of the water flow, the movable opening where the front and rear funnels of the front funnel are sleeved gradually opens backward or slowly closes forward, adjusting the discharge of the water body in the front funnel or the collection of water flowing into the inlet bucket of the rear funnel. It is an infinitely adjustable mechanism for large and small fluctuations in water flow velocity, adjusting the water collection range and the amount of water flowing into the rear funnel, and is used to cope with changes in water flow velocity, fast or slow, to improve the relative stability of the power generation quality of the water turbine and generator.

[0026] The resources used in the present invention are very rich, and it has strong environmental adaptability, effectively utilizing renewable resources. Its equipment system only uses the water surface, does not occupy land, and does not change the ecological environment. Its installed capacity can range from hundreds of watts, kilowatts, megawatts, or even over ten megawatts and above, to build various types of hydroelectric power energy bases; it can perform horizontal flowing water power generation in rivers, ocean currents, ocean waves, tidal currents, etc. It is especially suitable for use in densely populated areas or areas with relatively fast water flow around cities and rural areas. It aims to solve the problem that horizontal flowing water still mostly uses primitive traditional power generation modes, overcome the limitations of small power and low efficiency of existing horizontal flowing water power generation equipment, and avoid the high costs of building dams, power stations, resettling immigrants, and changing the natural ecology in hydropower stations, making efforts for the new development of hydropower.

[0027] For the front and rear funnels of the present invention, non-metallic or polymer functional composite waterproof materials are preferably used as much as possible. They have a relatively low specific gravity, are convenient for suspension in water, and can be modularly fabricated, transported, installed, and maintained in sections. Less materials are used, the cost is low, the construction period is short, the capital recovery period is short, and the economic and social benefits are very good.
