All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention aims to provide a savonius turbine booster pump, which solves the problems in the prior art, and the blade angle can be automatically adjusted, so that the capture capacity of blades of a savonius turbine for fluid is improved, and the energy conversion efficiency of the savonius turbine for the fluid is improved.
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.
The invention provides a savonius turbine booster pump, which is shown in figure 1 and comprises a savonius turbine 1 capable of automatically adjusting the blade angle, a centrifugal pump 2 and a water conveying pipeline 3. As shown in FIG. 2, savonius turbine 1 adopts blade 4 with arc-shaped or semicircular cross section, as shown in FIG. 4 and FIG. 5, the low-speed incoming flow is easy to start, the catching capability for incoming flow is good, and the self-starting capability of flat-plate type straight blade is poor, and high-speed incoming flow is needed; the blades 4 are provided with the transverse baffle plates 5 on the working surface, the transverse baffle plates 5 are used for conducting drainage, when the incoming flow impacts the blades 4, the transverse baffle plates 5 are used for horizontally restraining the incoming flow, so that the incoming flow uniformly and intensively acts on the blades 4, and the situation that the incoming flow generates longitudinal flow to cause kinetic energy dissipation is avoided; the horizontal baffle is used for restraining the fluid horizontally, meanwhile, the acting area of the fluid on the blades is reduced, the effect of the fluid on the blades is unfavorable for the inflow, the longitudinal flow impacts the horizontal baffle, the operation of the horizontal baffle is not favored due to the fact that the baffle is too thin and too high, the radius of a lower cover plate of the savonius turbine is taken as R, the distance between the horizontal baffles is 0.5R, the height of the baffles is 0.02R, and the thickness of the baffles is 0.02R. The blade 4 of the savonius turbine capable of automatically adjusting the blade angle is positioned in the middle of an upper cover plate 6 and a lower cover plate 7 of the savonius turbine 1, the upper cover plate 6 and the lower cover plate 7 are connected through a fixed shaft 8, the front edge of the blade 4 is fixed on the outer edges of the upper cover plate 6 and the lower cover plate 7, and the tail edge of the blade 4 can freely move, so that the automatic adjustment of the blade 4 angle is realized. In order to prevent the free swing of the non-working blades from interfering with each other under the action of the incoming flow, the arc length of the tail edge of the blade 4 is reduced, and the structure is shown in fig. 5, so that the swing amplitude of the non-working blades is weakened under the action of the water flow impact. A fixed baffle plate 9 is designed on the fixed shaft 8, the fixed baffle plate 9 and the fixed shaft 8 are integrated into a whole and are fixed, and the fixed baffle plate 9 has a restraining effect on the tail edge of the blade 4 when the blade 4 works. As shown in fig. 3, the arrow direction is the flow direction of fluid in the river channel 12, the blades 4 perpendicular to the flow direction are working blades, the blades 4 in other directions are non-working blades, the working blades impact the working blades, the working blades rotate around the front edge and the fixed points of the upper cover plate and the lower cover plate until the convex side of the working blades is abutted with the fixed baffle 9, the fixed baffle 9 constrains the angle of the blades 4, so that the working blades are always perpendicular to the flow direction, the flow is fully utilized, the fluid utilization rate is improved, and the working blades drive savonius turbines to rotate under the impact of the fluid; taking savonius turbine lower cover plate radius as R. As a core component, the fixed baffle needs to ensure its rigidity and strength, taking its thickness of 0.02R into consideration comprehensively, and its thickness can be increased appropriately if necessary. In designing the geometry of the fixed baffle 9, the fixed baffle 9 needs to be tangent to the non-working surface of the blade, so as to ensure that the incoming flow always acts vertically on the working blade when the working blade is in the working area, and maximize the utilization rate of the fluid. As shown in fig. 6, the working state change process of one working vane is shown in fig. 6, and the working vane is in a state of a position 1, a position 2, a position 3 and a position 4 respectively from left to right in fig. 6, and the contact positions of the non-working surface on the back surface of the vane and the fixed baffle are a tangent point 1, a tangent point 2, a tangent point 3 and a tangent point 4 respectively when the working vane is in the corresponding four positions from left to right; when the working blade is in the position 1, the working blade reaches the optimal working state, the incoming flow vertically acts on the working surface of the blade, the utilization rate of the incoming flow by the blade 4 reaches the maximum, the position 2, the position 3 and the position 4 are the positions of the follow-up working state of the working blade, and when the working blade is in the position 3, the blade 4 finishes working, but the incoming flow is impacted excessively, the direct conversion is performed to the non-working blade, the damage to the blade is larger, and the swing amplitude is excessively large under the impact action of the incoming flow, so the transition is performed through the position 4, and the incoming flow is reduced and then the non-working blade is converted. The tangential points of the working vane at the positions 1, 2, 3, 4 and the fixed baffle 9 are respectively tangential point 1, tangential point 2, tangential point 3 and tangential point 4, the included angles of the tangential points relative to the front edge of the vane and the horizontal direction are respectively 66 degrees, 85 degrees, 90 degrees and 92 degrees, and the vane 4 is always vertical to incoming flow in the transition process from the position 1 to the position 4; as shown in fig. 4 and 5, the tangent principle of the blade and the fixed baffle is combined, the radius of the arc of the working surface of the blade is 0.2R, the radius of the arc of the back surface of the blade is 0.24R, and the height of the blade is 2R. Considering that the blades are perpendicular to the incoming flow direction in the working area, the incoming flow fully acts on the working blades, and the swing of the blades under the action of fluid impact needs to be reduced as far as possible in the non-working area, so that the mutual interference among the non-working blades is prevented, and the included angle of the tail edge of the blade with respect to the center of the blade arc section and the horizontal direction is 50 degrees. The lower cover plate 7 is fixedly connected with the centrifugal pump shaft 10, and along with the rotation of the savonius turbine 1, the centrifugal pump shaft 10 is driven to rotate, and the centrifugal pump shaft 10 is arranged in the centrifugal pump 2 in a transmission way, so that the centrifugal pump 2 runs, and the supercharging is realized; the suction inlet of the centrifugal pump 2 is provided with the trash rack 11, as shown in figure 1, when fluid is sucked into the pump body, impurities, sediment and the like at the bottom of a river channel are prevented from being directly sucked into the centrifugal pump, and the blades 4 are prevented from being damaged; the water pumping chamber of the centrifugal pump 2 is externally connected with a water conveying pipeline 3, and water flows out of the water pumping chamber of the centrifugal pump 2 and then enters the water conveying pipeline 3, so that the water flow can be directly introduced into farmland irrigation through the water conveying pipeline 3.
