Abstract

PROBLEM TO BE SOLVED: To increase output efficiency of an impeller.SOLUTION: An outer impeller 6 and an inner impeller 3 of an impeller with a booster function constitute an impeller group 10 via a gear change power transmission device 7. The inner impeller is rotary-driven at a rotation speed higher than that of the outer impeller by fluid energy flowing in the impeller group, so as to rectify a turbulence flowing in the impeller group. The rectified fluid is circulated in the impeller group together with a centrifugal force, so as to boost the fluid energy to the outer impeller in a backflow region. In the impeller with the booster function, a flow introduction device such as a guide vane or a synchronous mechanism inevitable for a cross flow type watermill is omitted.

Description

The present invention has a cross flow type impeller with an inner impeller, the inner impeller rotates at a rotational speed faster than the rotational speed of the cross flow impeller, and is a vertical axis cross flow type impeller in a reverse flow region. A mechanism that boosts the fluid force to the curved blades and enables extraction of rotational energy from the curved blades in the backflow region is also provided.

In open channels such as mountain streams and agricultural canals, cross-flow turbine generators with a simple turbine structure and easy installation and maintenance are being used as a means of effectively using low-head and low-level water flow energy. It is.
However, in the case of a cross-flow type turbine, it is difficult to generate vibration and rotation because it receives a large resistance to the counter-flow to the turbine blades. A precision flow guide device such as a synchronous adjustment mechanism for rotational speed is required, and it has been desired to solve these problems.

For example, as shown in Non-Patent Document 1, when the entire water wheel is submerged, it receives a large back flow resistance in the back flow region to the impeller, so that the back flow received by the blade in the back flow region is parallel to the flow of the peristaltic blade. Figure 1 on page 1 of Chapter 1 of Non-Patent Document 1, with a tension spring attached between the blade shaft and the turbine wheel flange so that it backs up and automatically escapes the reverse flow and generates a restoring force according to the swing angle. There is a conventional technology that developed a peristaltic impeller as shown in Photo-1.

In addition, the water turbine shown in Non-Patent Document 1 is provided with a weir and a water catching plate at the water inlet of the water turbine without providing a drop pipe in the guide pipe and guide vane and the outflow part that are indispensable for the cross-flow water turbine. There is a technology that raises the pressure head and uses the head of the water level that flows through the turbine to accelerate the flowing water in the turbine to increase the output efficiency.

In addition, in the technique shown in Patent Document 1, in order to efficiently send the fluid to the rotor blades, a partition and a guide portion 14 are provided between the pair of rotor blades to draw water and measure the water guiding effect. As described in Chapter 3, page 27 of Non-Patent Document 1, there is a technique for increasing the output efficiency by increasing the pressure head by providing a weir or a water drainage plate at the water inlet of the water turbine.

National Land Policy Research Institute Document No. 328 Survey Report on Utilization of Flowing Water Energy (Chapter 1, Page 3, Chapter 3, Page 27) Ohara Gear Industry Co., Ltd. KHK STOCK GEARS3006 vol.8 (August 20, 1994 revised 8th edition P294-295)

The problem to be solved is that according to the mechanism described in Non-Patent Document 1 (see page 1 of Chapter 1), the peristaltic resistance of the impeller received by the impeller in the backflow region is oscillated in parallel to the flow. Using a mechanism that escapes backflow and automatically restores with tension springs, omits guide vanes and synchronization mechanisms, etc., however, when vortex or discontinuous pulsating current flows into the peristaltic turbine And, when the output load of the peristaltic turbine changes rapidly in a short cycle, the elevation angle of the blades changes according to the fluid force and the vortex behind the blade, and the strength of the tension spring provided between the blade shaft and the turbine flange portion is In the case of non-automatic, it is not possible to cope with the fluctuation in the elevation angle of the blade and transient phenomenon, the elevation angle of the blade pulsates discontinuously, the fluid force pulsating the discontinuity is amplified, and the rotation of the impeller irregularly rotates. To deal with this phenomenon that may cause vibration damage However, it is necessary to automatically control the strength of the tension spring, the revolution position of the water wheel, and the fluid force against the peristaltic blade, and there are problems in practical application.

In addition, the water turbine shown in Chapter 3 page 27 of the National Institute of Advanced Industrial Science and Technology (NIST) is a constricted water transfer device. The head of the water level that flows through is used to accelerate the running water in the turbine to increase the output efficiency.
However, it is not possible to increase the output efficiency by installing a water collecting plate or a weir at the water inlet of the water turbine to raise the water level and utilize the water level difference between the water turbine inlet and the water outlet to accelerate the running water in the water turbine. In the case of a shaft-type cross-flow turbine, a characteristic is that a large amount of flowing water that has flowed through the turbine wheel acts again on the turbine blades near the drain to increase the efficiency. Since the turbine blades extend in parallel to the axial direction of the turbine wheel, the flowing water that acts on the turbine blade blades near the drain port is drained and slanted with a gradient along the turbine blade blade, The larger the drop in the water level at the drain and the outlet, the less the fluid force acting on the turbine blades, and it does not act sufficiently in the direction of rotation, especially as the rotational speed of the turbine blades decreases, the flow from free surface flow As the water flows through the impeller, the water level drops rapidly, Fluid force use is weakened.
Therefore, there is a problem in that there is a contradiction that contradicts the effect of increasing the output efficiency due to the head and the characteristics of the crossflow turbine.
(Non-Patent Document 1) (See Chapter 3, pages 27-28)

In addition, in the invention disclosed in Patent Document 1, in order to efficiently send the fluid to the rotor blades, a partition and a guide portion 14 are provided between the pair of rotor blades to draw water and measure the water guiding effect. Although there is a problem that a drag load is applied to the rotation of the rotor blades when water is present in the reservoir portion Z on the opposite side of the fluid flow side of the fluid guide portion 14 of the casing 12, an attempt is made to solve the problem. Because of this, problems remain.

In order to solve the above problems, the present invention described in claim 1 will be described in detail with reference to FIGS.
A plurality of boost blades 2 are provided around a conical boss 1 fitted to the rotation output shaft 15, and a plurality of curved portions are provided on the “inner impeller 3 fixed integrally with the conical boss”. The outer impeller 6 around which the mold blades 4 are provided is connected to the rotary output shaft 15 that is provided on the inner impeller 3 so that the bearing portion 5 of the outer impeller 6 is interposed via the transmission power transmission device 7. And set up the impeller group 10.
Further, the outer peripheral edge 8 of the inner impeller 3 and the inner peripheral edge 17 of the curved blade 4 provided around the outer impeller 6 are spaced apart from each other, and the section is defined as a through flow path 9.

The present invention of claim 2 will be described in detail with reference to FIGS.
A portable vertical axis cross-flow hydraulic power generation device 74 (hereinafter sometimes abbreviated as a power generation device 74) using the impeller group 10 is submerged in the water in which the flow is generated, and the power generation device is used. The forward water 21 flowing in from the inlet 20 provided in the impeller part 19 of the casing 61 of 74 has rotationally driven the inner impeller 3 and the outer impeller 6 of the impeller group 10 provided in the impeller part 19. The inner impeller 3 and the outer impeller 6 are rotated in cooperation with each other by means of the transmission power transmission device 7, and the inner impeller 3 is faster than the rotational speed of the outer impeller 6. The rotation output shaft 15 that rotates in the same direction and protrudes from the inner impeller 3 is rotatably supported by the main bearing portion 28 provided on the cover plate 33 of the impeller portion 19, and the rotation that penetrates the shaft is supported. The output shaft 15 is electrically driven by the frame 63. Transmission and to drive on the machine 71.

The change of the flowing water flowing through the impeller group 10 by the operation of the impeller group 10 will be described in detail with reference to FIG.
The impeller group 10 provided in the impeller part 19 includes an inner impeller 3 having boost blades 2, an outer impeller 6 having curved blades 4, and a transmission power transmission device 7. The forward flow water 21 flowing in from the flow inlet 20 of the 19 fluid acts on the curved blades 4 and the boost blades 2 and receives the resistance of the blades to reduce the flow velocity, thereby flowing the overflow water flow 12, It flows as a through-flow water 11 including a wing vortex 13 and turbulent flow, and the flow-through water 11 is formed by a boost blade 2 fixed to the inner impeller 3 and a conical boss 1 in the process of flowing through the through-flow passage 9. By rotating means, the through-flow water 11 including the wing vortex 13 and the turbulent flow is lifted up in the boss apex direction 23 to prevent commutation and is provided in the vicinity of the discharge opening 14 while performing synthetic rectification. Back surface of curved blade 4 extending parallel to the axial direction The fluid force is again applied to the upper part of 4 to forcibly inject between the wings of the curved blade 4 and drain 49, and even when the rotational speed of the curved blade 4 decreases, Through water 11 that flows through the drain opening 14 is forced to drain 49 through the drain opening 14 to accelerate the flow velocity in the impeller 19 and increase the output efficiency. Therefore, it is the most important feature that resolves the contradiction conflicting with the head effect of Non-Patent Document 1 and the characteristics of the crossflow turbine.

The forced drainage will be described in detail with reference to FIG.
The peripheral speed of the curved blade 4 (hereinafter simply referred to as the curved blade 4) fixed to the outer impeller 6 is equal to the flow velocity of the forward water 21 flowing from the flowing water inlet 20 of the impeller portion 19. When the flow speed of the forward flow water 21 is high, the rotational speed of the curved blade 4 is high, and the forward water 21 in which the fluid force acts on the curved blade 4 receives the resistance of the blade, The water is discharged along the back surface 24 of the curved blade 4 by spraying while the flow velocity is attenuated.
Further, when the flow velocity of the forward flow water 21 is low, the rotational speed of the curved blade 4 is in a low speed state, and the fluid force acting on the blade of the forward flow water 21 decreases as the rotational speed decreases, and the impeller group 10 has an internal speed. While flowing through the central portion, the water surface gradient is drastically lowered, and drainage 49 is performed along the back surface 24 of the curved blade 4 near the discharge opening 14 while attenuating the resistance of the blade against the forward water 21. Therefore, the curved blade When the rotational speed of 4 is high or low, the curved blades 4 extending parallel to the axial direction in the vicinity of the drainage do not have sufficient fluid force, and the characteristics of the crossflow turbine cannot be utilized.

Therefore, regardless of whether the rotational speed of the curved blade 4 is low or high, the shape of the boss fixed to the inner impeller 3 is inclined and reduced in the apex direction as means for forcibly draining the through water 11 from the discharge opening 14. 23. Using the means of the transmission power transmission device 7 in which the rotational speed of the inner impeller 3 is higher than the rotational speed of the outer impeller 6 and rotates in the same direction, the flow-through water 11 is scraped in the apex direction of the boss 1. The peripheral speed of the curved blade 4 rotating in accordance with the flow velocity of the forward water 21 in the vicinity of the discharge opening 14 near the discharge opening 14 is prevented by accelerating flowing water with centrifugal force and preventing the jet near the discharge opening 14. The flow between the wings of the “curved blades 4 extending in parallel to the axial direction” is discharged and drained in the upper direction of the curved blades 4 at a much higher flow rate, contributing to the rotational torque of the curved blades 4. The excess turbulent water from the curved blade 4 ”And the curved blades 4 are forced to drain efficiently regardless of whether the rotation of the curved blades 4 is high or low. Therefore, the flow of water in the impeller group 10 is accelerated without depending on the head, and the output efficiency is increased. This is the most important feature that resolves the contradiction conflicting with the head effect of Non-Patent Document 1 and the characteristics of the crossflow turbine.

The setting means for rotating the inner impeller 3 at a value far exceeding the peripheral speed of the curved blade 4 is, as shown in FIGS. 2 and 7, planetary gear B82 and sun gear A81 of the transmission power transmission device 7. And the number of teeth of the ring gear C83 are selected so that the rotational speed of the inner impeller 3 is higher than the rotational speed of the outer impeller 6, and the rotational output shaft of the inner impeller 3 is also set. The output power of a permanent magnet type motor / generator (hereinafter also referred to as a generator 71) that is driven via the power supply 15 is time-divided, and the duty ratio is set to about 1/20. The generator 71 and the motor are time-divided to drive the rotary output shaft 15 and assist the rotation of the inner impeller 3 to adapt to the flow velocity of the forward water 21. The peripheral speed of the curved blade 4 that rotates is apparently stopped. Realized by adjusting the stomach condition.
Further, since the main subject of the present invention is the utilization of the fluid system of the impeller, description of the electrical relationship is omitted.

The inner portion of the third aspect (hereinafter sometimes referred to as boost inner portion 25) will be described in detail with reference to FIGS.
A flat plate is provided around the outer peripheral edge of the impeller portion 19 on the reverse flow region side from the positioning column 55 provided at the flowing water inlet 20 to the exhaust pipe 38 in the circumferential direction, and the inner periphery of the booster inner portion 25 is provided. A section in which the section of the wall surface 30 and the conical surface 23 inclined to the apex direction of the conical boss 1 fixed to the inner impeller 3 is formed in a trapezoid-like shape 42 extends from the drainage weir 75 in a counterclockwise direction. A section extending to the positioning column 55 is defined as a booster flow path 36.

,
The forward water 21 flowing through the through-flow passage 9 acts again on the back surface 24 of the curved curved blade in operation near the discharge opening 14, attenuates and drains by receiving the resistance of the curved blade 4. Both drainage and drainage forcibly drained by the rotating means of the boost blades 2 drain from the drain opening 14, and the excess water running water 43 leaked from the drainage 49 and the regenerative from which a part of the through water 11 leaked The stream 44 passes through the drainage weir 75 while accelerating by the rotating means of the boost blade 2 and circulates through the booster flow path 36 as the boost flow 45. In the circulating process, the boost flow 45 is integrated with the boost blade 2. It is lifted up in the apex direction of the conical boss 1 to prevent the jet flow, boost the fluid force to the back surface 24 of the curved blade 4 near the backflow region, and drive the curved impeller 6 near the backflow region.

Further, the boost flow 45 is prevented from jumping out and flowing out from the outer periphery of the impeller portion 19 in the process of circulating the booster flow path 36 by means of the booster inner portion 25 provided on the outer periphery of the impeller portion 19. And the agglomerated boost flow 45 boosts the fluid force to the back surface 24 of the curved blade 4 so that the air resistance at the back surface 24 is greater than that at the surface 18 of the curved blade 4. Thus, a rotational force is generated in the rotation output shaft 15 in the direction in which the back surface 24 is pushed, overcomes the reverse flow resistance received by the impeller group 10 in the reverse flow region, and the rotational torque is extracted also from the curved blade 4 on the reverse flow region side. This is the most important feature beyond the defects of peristaltic turbines, without the need to automatically control the strength of the tension spring, the revolving position of the turbines and the fluid force against the peristaltic wings.

In addition, as shown in FIG. 4, a casing 61 in which the impeller group 10 according to claim 2 is installed in the impeller portion 19 of the casing and is submerged in the water in which the flow is generated, As shown in FIGS. 5 and 6, the vehicle portion 19 and the booster inner portion 25 are configured by the vehicle portion 19 and the booster inner portion 25, and each portion includes a bottom plate 37 and a cover plate 33, and the inclined side plate 51 and the booster of the water guide portion 27. By the means of the inner portion 25, the flowing water flowing around the pool portion 57 between the inside of the impeller portion 19 and the inner wall surface L52 of the side groove 60 is cut off, and the fluid flow side of the guide portion, which is the subject of Patent Document 1, is a problem. It is characterized by effectively eliminating the effect of accumulated water on the opposite wall surface.

In addition, as a conventional technique, a technique described in Chapter 3 page 27 of Non-Patent Document 1 for providing a weir and a water-feeding plate at a water inlet of a water turbine to raise a pressure head, and a method for efficiently supplying fluid to a rotor blade as shown in Patent Document 1 In order to feed the water into the water, any technique of providing a partition between the pair of rotor blades and the guide portion 14 to raise the water surface and the water head is a cross-flow type in order to cope with a sudden change in the flow rate and flow velocity of the influent water. The impeller is indispensable for a conduction guide synchronization function, and the above-described mechanism alone cannot be expected to have an effect as a conduction device. According to the present invention, the “casing 61 in which the impeller group 10 is installed” is formed. The inclined side plate 51 provided in the water guide portion 27 is a condition in which the terminal 56 of the inclined side plate 51, the positioning column 55 of the flowing water inlet 20, and the starting point 40 of the booster inner portion 25 are fixed to the positioning column 55. By filling, flow Even when there is a sudden change in the flow rate or flow rate of the incoming water, a synchronization mechanism or the like is not necessary, and the power generation device 74 having a function that can omit guide vanes essential to the crossflow type impeller is a main feature.

With the above configuration, an apparatus having the following effects can be provided.
Like the peristaltic impeller, the backflow received by the blades in the backflow region is automatically released in parallel with the peristaltic blades so that the backflow is restored and the blades are restored in the forward flow region. There is a conventional technology that raises the water level and accelerates the running water in the water turbine using the head with the drain outlet to increase the output rate, but even without using such a problematic mechanism The outer impeller and the inner impeller are provided with a transmission power transmission, and the inner impeller is rotated in the same direction at a higher speed than the outer impeller. And the conical boss fixed to the inner impeller, the reverse flow resistance that the impeller receives in the reverse flow region is overcome, the flow of water in the impeller is accelerated and the jet flow is prevented, and the characteristics of the cross flow type impeller are improved. Indispensable gas for the cross flow type impeller. There is an advantage that it is possible to omit the Doben and synchronization mechanism guiding flow devices or the like.
