Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-6, an intelligent and efficient water turbine volute for a hydroelectric power generation device according to an embodiment of the present invention includes a casing 1 formed by two tangent drums, the top of the tangent portion of the casing 1 is communicated with a water inlet pipe 2, flow guide channels 3 having an arc structure are symmetrically disposed on the bottom surface of the casing 1, the flow guide channels 3 are communicated with the inner side of the casing 1, the bottom ends of the two flow guide channels 3 are both communicated with the water inlet end of a water outlet pipe 4, and the water outlet pipe 4 is located at the bottom of the tangent portion of the casing 1.
Impeller 5 is installed to the inboard symmetry of casing 1, evenly is provided with a plurality of blades 6 on impeller 5, and the part that blade 6 is close to casing 1 inner wall is provided with flexion 7, and one side that inlet tube 2 was kept away from to blade 6 is provided with reinforcing plate 8.
Wherein, the same velocity of flow, under the condition of equal time, the flow of two water conservancy diversion way 3 is greater than the flow of inlet tube 2, the flow of outlet pipe 4 is greater than the flow of two water conservancy diversion way 3, the water of inlet tube 2 gets into casing 1 respectively, 3 discharges of rethread water conservancy diversion way, in order to guarantee impeller 5's rotating resistance reduces, and rivers are to the thrust of blade 6, must in time discharge the water of casing 1 inside as far as possible, water through 3 discharged water of water conservancy diversion way finally collects in outlet pipe 4, therefore, also guarantee that outlet pipe 4 can quick drainage.
Wherein, inlet tube 2 sets up for the slope, and inlet tube 2 keeps away from the one end of casing 1 and is higher than the one end of being connected with casing 1, and inlet tube 2 is the toper structure, and the slope of inlet tube 2 sets up and the design of toper structure for the velocity of flow of rivers that get into in casing 1 accelerates, increases the effort increase to blade 6, realizes stronger thrust.
Wherein, impeller 5 cover is located on the transmission shaft, and the top of transmission shaft runs through the top surface of casing 1 and is connected with the transmission of generating set 9, sets up generating set 9 in the top of casing 1, through with casing 1 with water culvert or runner be connected can, whole equipment especially generating set 9 do not contact with water, life is longer.
Wherein, all be provided with fixed plate 10 on the casing 1, casing 1 passes through fixed plate 10 and is connected with outside fixing device for whole hydraulic turbine spiral case that is used for hydroelectric device can be fixed through fixed plate 10, also can loosen fixed plate 10 and remove when not using.
The convex surface on the bending part 7 is the same as the flowing direction of the water flow, so that the acting force of the water flow on the blades 6 is concentrated at the bending part 7, and the water flow can more easily push the impeller 5 to rotate.
Wherein, impeller 5 and blade 6 are the corrosion-resistant plastics material of high strength for impeller 5 and blade 6's dead weight is lighter, reduces the storage of self kinetic energy, and corrosion-resistant material can strengthen blade 6 and impeller 5's life simultaneously.
The working principle is as follows: fix casing 1 horizontal installation in suitable position through fixed plate 10, introduce rivers in inlet tube 2, end flow direction lower position's the play water end of intaking through the higher position of inlet tube 2, and accelerate the rivers that flow into casing 1 inside jointly through the toper structure, because rivers flow in from the middle part of casing 1 tangent part, consequently the impeller 5 of symmetry setting all receives the effort of rivers, because flexion 7 is close to casing 1 inner wall department, the rivers velocity of flow here is bigger relatively, consequently the effort is bigger, leverage through blade 6, the effort of rivers is enlarged, promote impeller 5 more easily and rotate, thereby make the transmission shaft of installation impeller 5 rotate thereupon. The impeller 5 rotates under the action of water flow, when the water flow reaches the guide channel 3, the water flow flows into the guide channel 3 under the action of self gravity, the water flow pushing the blade 6 gradually flows into the water outlet pipe 4 from the guide channel 3, when the blade 6 is impacted by the water flow flowing in from the water inlet pipe 2 again, the water flow originally flowing into the shell 1 completely flows out through the guide channel 3 and cannot be pushed by the blade 6, and the two impellers 5 rotate rapidly under the action of the water flow.
