Description
Technical field
The utility model relates to and utilizes ocean current to carry out hydroelectric new equipment, particularly can resist the new method that the gravity type of typhoon can be generated electricity with ocean current.
Background technique
Marine energy becomes each maritime state government the sixth of the twelve Earthly Branches and lists development plan in the domestically produced energy strategic framework in.Developed country begins to carry out the research and development of ocean energy very many years ago with regard to oneself.No matter utilize the research and development situation of ocean current, trend, morning and evening tides and wave energy to investigate, find that the generating of which kind of form and the utilization of resources all exist four problems to occur improving the ground solution as yet to China and developed country in recent years; 1, resists that typhoon 2, built on-site 3, stability fix 4, electric motor power.
Summary of the invention
The utility model provides a kind of power station that utilizes energy by ocean current to generate electricity, can improve capacity of installed generator, reach the above generating scale of MW class by big spoke.The power station is simple in structure, can site operation, Safety performance is good, can resist typhoon billow, can prevent seawater corrosion, the power generation device from sea current of good, the similar island of stability shape.
The utility model is finished by following technological scheme:
A kind of reinforced concrete construction of similar big raise bridge pier shape over strait.Build up back the seeing of generating and exactly like deepwater islands and reefs from the sea, or the landing stage.It is installed in the generating island by high-strength density trash rack and conflux cover, head pressure pipe, low water head tubular turbine, draft cone, pipe, draft tube, bearing support, water distributor, flywheel and generator.Water turbine and generator are installed in the inner space of the generating island body of reinforced concrete structure, body middle part, generating island is provided with the conflux cover, the import of conflux cover is square and is provided with trash rack, the conflux cover is connected with aqueduct with the head pressure pipe, be provided with draft cone in the aqueduct, speed regulator and low water head tubular turbine, water turbine and coupling, flywheel, bearing support, generator connects successively, the aqueduct afterbody is connected with the drop tail pipe, drop tail pipe front end is provided with the tail water butterfly valve, the rear end is provided with outlet and trash rack, enters in the water turbine to prevent marine organisms from the habit of swinging current being arranged to cause the accident.Generating body bottom, island is provided with water chamber, and bodies top is provided with electric power master control room, water tank, signaling lamp, radar, lightning arrester on the generating island.Between water chamber and water tank, be provided with water pump and be provided with intake pipe and valve.
The utility model working procedure: be provided with the conflux cover behind the trash rack, the conflux cover is square, connects the head pressure pipe behind the conflux cover, the transverse section of head pressure pipe can be circular or square, is provided with the low water head tubular turbine in the pipe.Be provided with into water butterfly valve between tubular turbine and the head pressure pipe, the sweptback draft tube of another termination of pipe, the draft tube transverse section can be circular or square, and the draft tube rear portion is provided with the tail water butterfly valve, and tubular turbine is connected with generator, the bearing support of installation in the generating island.Stretch out top, sea and be provided with electric power control room and working room, working room's roofdeck is equipped with lightning conductor and signaling lamp and water tank.
After natural ocean current enters the conflux cover, increased the density and the flow velocity of water, its fluidised form becomes rapidly varied flow in the head pressure pipe because the continuous extruding of current is fallen into, through the adjusting of water distributor.Thereby the potential energy of current and inertial force strengthen and have driven water turbine and convert mechanical energy to and order about the generator operation generating.Release draft tube through the current after the water turbine work done with gradually varied flow situation.Because the outer flow velocity of generating island and draft tube is apparently higher than the flow velocity that enters after the draft tube work done.The water that flow velocity is high is taken the low water of flow velocity and is formed the stronger power of the dragging diffluence downstream of taking.
The utility model has utilized the carrier of gravity-type reinforced concrete structure as the power station.With cement for construction in sea and steel plate materials mixing construction, the tubular hydraulic generator unit of then that routine is traditional low water head is placed in it, and the generating island is built in through generating electricity in the waters that surveys the suitable rivers that generate electricity, lake, sea.Can offer resident and fisherman and army life stationed on the island production electricity consumption on seashore and the island.The utility model patent has simple and compact for structure, and construction cost is low, the investment gain quick return, the feature of environmental protection good, safe and reliable, the characteristics of generating efficiency height, good stability.The scientific level and the manufacturing technology in the present age can be built marine building weight, large-scale fully, bore as offshore oil and open platform and facilities such as bridge spanning the sea and seabed tunnel.The utility model power station is simple in structure, can site operation, Safety performance is good, can resist typhoon billow, can prevent seawater corrosion, stability is good.
