Description

Technical Field

[0001] The utility model relates to the technical field of water turbine water diversion and power generation, in particular to a water turbine water diversion structure and water turbine power generation equipment. Background Art

[0002] Existing household water turbines mostly adopt oblique impact or turbine structures, and their volume and power generation capacity are generally small. In addition, there is also a waterwheel-type water turbine, which has a larger volume and power generation capacity. It usually includes a trapezoidal steel support frame, a rotating shaft, round seats on both sides and a circle of guide vanes welded between the round seats. When in use, this structure is mostly set at the outlet of a drainage structure with a larger pipe diameter.

[0003] Among them, since the waterwheel-type turbine is mostly used for drainage structures with larger pipe diameters, the distance between the circular seats on both sides is large (this distance is sometimes close to the diameter of the circular seat). At the same time, the axial length of a single guide vane is also long, so the impact area and impact force of water each time are also large. The overall rotating structure of the water wheel continues to rotate under the impetus of intermittent large impulses. Among them, since there is often a large distance between the circumferential guide vanes, the force interval of the water wheel rotating structure is long, which is easy to affect the balance of the rotational torque, and then easily affect the power generation effect. In addition, if the number of circumferentially arranged guide vanes is simply increased, the above problems can be alleviated to a certain extent. However, since the guide vanes are longer, this will also significantly increase the use of raw materials and the overall weight. At the same time, the requirements for hydraulic power will also be higher. Utility Model Content

[0034] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0035] This embodiment provides a water turbine water guide structure, please refer to Figure 1-5 As shown, it includes a water wheel mechanism 100 and a receiving mechanism 200; the water wheel mechanism 100 has a pivotal mounting portion 110, and a plurality of mounting seats 120 and a plurality of guide vane plates 130 arranged around the pivotal mounting portion 110; the pivotal mounting portion 110 is pivotally mounted to the receiving mechanism 200; the plurality of mounting seats 120 are arranged at intervals along the axial direction, and each group of guide vane plates 130 is installed between adjacent mounting seats 120; wherein, two axially adjacent groups of guide vane plates 130 are arranged in a circumferentially staggered manner.

[0036] Specifically, the pivotal mounting portion 110 may be a pivot shaft or a connected sleeve and shaft; the shape and installation of a single guide vane 130 may refer to the prior art and will not be described in detail herein; the guide vane 130 may be welded between adjacent mounting seats 120; the two axially adjacent groups of guide vanes 130 are circumferentially staggered, which can shorten the force interval between the circumferential guide vanes 130, thereby improving the balance of the rotational torque and further improving the power generation effect.

[0037] In this embodiment, in two axially adjacent groups of guide vanes 130 , one guide vane 130 in one group is located in the middle of two circumferentially adjacent guide vanes 130 in the other group.

[0038] Specifically, a guide vane 130 in one group is located in the middle of two circumferentially adjacent guide vanes 130 in another group, that is, the guide vanes 130 of two adjacent groups are circumferentially staggered by half a pitch, as shown in the figure. The structure is relatively simple and reasonable, and is easy to layout and install.

[0039] In this embodiment, the number of groups of the guide vanes 130 is an even number greater than zero, and correspondingly, the number of the mounting seats 120 is an odd number.

[0040] Specifically, when the number of groups of the guide vanes 130 is an even number greater than zero, and at the same time, two axially adjacent groups of guide vanes 130 are staggered in the circumferential direction, the number and arrangement of the guide vanes 130 subjected to force each time are consistent, which can ensure the balance of the rotational torque.

When an odd number is used, one is arranged in the middle of the pivotal mounting portion 110, and the rest are symmetrically arranged on the pivotal mounting portion 110.

[0042] Specifically, the mounting seats 120 of the same shape are symmetrically arranged, or simultaneously arranged in the middle, so that the gravity of the water wheel mechanism 100 can be evenly distributed, thereby ensuring the stability of the structure and rotation.

[0046] Specifically, such as Figure 2 As shown, when the mounting seat 120 is annular, the mounting seat 120 can be set on the pivot portion 110 through the support frame 140; wherein the support frame 140 can be a vertical frame set only on the mounting seats 120 on both sides, or a horizontal frame can be set between the vertical frames on both sides.

[0047] In this embodiment, the receiving mechanism 200 adopts a receiving frame or a water tank structure.

[0048] Specifically, when a water tank is used, the receiving mechanism 200 can also be used as a container for storing or transferring water; in addition, when used for power generation, the internal water needs to be discharged in time before it approaches the lowest guide vane 130 to avoid increasing the rotational resistance.

[0049] This embodiment also provides a hydro turbine power generation device, please refer to Figure 4-5 As shown, it includes the turbine water guide structure, water guide mechanism 300 and power generation mechanism 400 described in any one of the above items; the water guide mechanism 300 has multiple water outlets 321, and the multiple water outlets 321 respectively correspond to multiple groups of guide vanes 130; the pivot part 110 is provided with a transmission end, and the power generation mechanism 400 is transmission-connected to the transmission end.

[0050] Specifically, when one end of the pivotal portion 110 serves as a transmission end, it is used to be directly connected to the power generation mechanism 400 through a transmission mechanism.

[0051] In this embodiment, the water diversion mechanism 300 has a connected main pipeline 310 and at least two branch pipelines 320 , and each branch pipeline 320 is provided with a plurality of water outlets 321 .

[0052] Specifically, a single main line 310 is connected to at least two branches, and each branch is provided with a plurality of water outlets 321 , so as to evenly drain water from each guide vane plate 130 while minimizing the use of pipelines.

[0053] In this embodiment, a speed-increasing transmission mechanism 500 is further included, and the speed-increasing transmission mechanism 500 is connected between the transmission end and the power generation mechanism 400 .

[0054] Specifically, the speed-increasing transmission mechanism 500 may adopt a speed-increasing transmission chain set or an independent speed-increasing box as shown in the figure, which is used to increase the speed of the transmission shaft to match the rated speed of the generator.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
