Description
Technical field
A kind of dull and stereotyped rotating vane hydroelectric installation, belongs to hydro-electric power generating equipment technical field, particularly relates to a kind of dull and stereotyped rotating vane hydroelectric installation.
Background technique
Traditional hydroelectric installation adopts water turbine, and impeller is all surrounded, and introduced wherein by water with pipeline, structure is more complicated, is inconvenient to disperse to use, and should build wet pit specially, build dam, build water power plant, costly.
Summary of the invention
The object of the invention is the above-mentioned deficiency overcoming existing hydraulic power generation technology, invent the simple dull and stereotyped rotating vane hydroelectric installation of structure that the higher convenient dispersion of a kind of efficiency uses.
A kind of dull and stereotyped rotating vane hydroelectric installation, comprises deflector, left-hand rotation leaf device, right-hand rotation leaf device, left generator and right generator.Deflector is the symmetrical hollow and the special-shaped box body sealed that are surrounded by base plate, top board, left sideboard and right sideboard, the base plate of deflector and top board horizontal arrangement, left sideboard and right sideboard are vertically arranged, deflector afterbody is more tapering than deflector head.Left-hand rotation leaf device is identical with working principle with right-hand rotation leaf device structure, and symmetry is arranged on the arc notch place on the base plate of the left and right sides of deflector.Left generator keep left be fixedly mounted on deflector base plate below, its input shaft is connected with the main shaft of left-hand rotation leaf device; Right generator keep right be fixedly mounted on deflector base plate below, its input shaft is connected with the main shaft of right-hand rotation leaf device.Left generator and right generator carry out water-proofing treating, and their security level is IP68.In the structure weight of this device and deflector, empty size can be guaranteed: this device being put into water can submerged or float, and only has at most top board surface and be horizontal when floating.If when can not reach requirement, solved by the method in base plate lower surface appropriate location counterweight.The use occasion of this device is that the depth of water exceedes this device height and current faster in rivers.The mounting type of this device has two kinds: the first adopts the mode that tangles of positioning rope, and one end and the base plate front end of positioning rope are connected, the other end of positioning rope the front of this device be fixed on fluviatic object such as bridge pier or pile and be connected.The second is directly installed on by this device on a positioning vertical column be fixed at the bottom of river, be connected with positioning vertical column by the hole of base plate front end, this device can around the flexible switch of positioning vertical column, automatically deflector head can be carried out flow path direction, deflector afterbody direction towards downstream towards upstream.Submersible this kind of device is only suitable for the second mounting type.
The structure of right-hand rotation leaf device is: the rotating vane that the right-hand rotation leaf device structure that to comprise main shaft, central gear different with the setting angle of six, seven of being evenly distributed on around central gear or eight only blade is identical.Main shaft is vertically arranged, the stage casing of main shaft is connected in the center hole of central gear by bearing and central gear, and main shaft can flexible rotating in the center hole of central gear.Central gear is fixedly mounted on the base plate of deflector by its termination.Each rotating vane comprises arm axle, rachis, nearly heart gear, arm axle sleeve pipe, heart gear far away, leaf-teeth wheel and blade.Blade is that Rectangular Rigid is dull and stereotyped.The rachis lower end that be fixed on rachis vertical with arm axle, rachis is vertically arranged, arm axle horizontal arrangement.The upper end of rachis to be taken turns with leaf-teeth by bearing and is connected, and leaf-teeth wheel can around rachis flexible rotating.The termination of leaf-teeth wheel and blade are fixed on the following center place of blade.Rachis and blade are in same vertical plane.Arm axle sleeve pipe is contained in around arm axle stage casing by bearing housing, arm axle can in arm axle sleeve pipe flexible rotating.Nearly heart gear and heart gear far away are fixed on the two ends of arm axle sleeve pipe respectively.Heart gear far away and leaf gears meshing, its velocity ratio is 6: 1.The upper end of main shaft is vertical with the arm axle of all rotating vanes to be connected.The nearly heart gear of all rotating vanes all engages with central gear, and the velocity ratio of central gear and nearly heart gear is 1: 3.Central gear, nearly heart gear, heart gear far away and leaf-teeth wheel all adopt umbrella gear.Assembling right-hand rotation Ye Qishi, when guaranteeing that the arm axle of its arbitrary rotating vane is in its main shaft front-right lateral attitude, the blade of this rotating vane and this arm axle are in same horizontal vertical plane, and now the blade of this rotating vane and the angle of this arm axle are 0 °.
The number of the rotating vane of left-hand rotation leaf device is identical with the number of the rotating vane of right-hand rotation leaf device.Assembling left-hand rotation Ye Qishi, when guaranteeing that the arm axle of its arbitrary rotating vane is in its main shaft front-left lateral attitude, the blade of this rotating vane and this arm axle are in same horizontal vertical plane, and now the blade of this rotating vane and the angle of this arm axle are 0 °.
The arc notch of the deflector left and right sides is the circular arc cutaway that cornerite is about 180 °, the blade on the right side of the main shaft of left-hand rotation leaf device is encased by the circular arc cutaway in left side substantially, and the blade in the left side of the main shaft of right-hand rotation leaf device is encased by the circular arc cutaway on right side substantially.
The working principle of right-hand rotation leaf device is: when the arm axle because of each rotating vane is in main shaft front-right lateral attitude arm axle and blade coplanar, and the velocity ratio that central gear and leaf-teeth are taken turns is 2: 1.By the structures shape of right-hand rotation leaf device, water flows through from front, and the water side being in the blade on the right side of main shaft is far longer than the water side of the blade be on the left of main shaft.See from top to bottom, namely overlook right-hand rotation leaf device, under the promotion of water, right-hand rotation leaf device will be rotated in a clockwise direction.And because of the existence of deflector, blocked the blade on the left of main shaft, incoming flow can not directly shift the blade be on the left of main shaft onto, and such right-hand rotation leaf device can turn faster, and efficiency can be higher.
See from top to bottom, namely this dull and stereotyped rotating vane hydroelectric installation is overlooked, its working principle is: under the effect of stronger incoming flow, this device can automatic adjustment direction, make deflector head just to carrying out flow path direction, under the effect of deflector, incoming flow is divided into left and right two stocks and does not flow to deflector caudal directions from the left and right sides of this contrive equipment in deflector head front, converge at the rear of deflector afterbody again.Left side flowing water drives left-hand rotation leaf device to rotate counterclockwise and drives the generating of left generator rotation, and right side flowing water drives right-hand rotation leaf device to rotate clockwise and drives right electrical power generators.
This contrive equipment efficiency is higher, and can flow to and be automatically adjusted to the best and to meet water orientation by Automatic-searching.Extensively can disperse the rivers generating being used in flowing.The electricity sent exports electric treatment system on the bank to by cable.
