Description

Technical Field

[0001] This utility model relates to water turbines, and more particularly to a suspended bucket turbine, belonging to the field of mechanical technology. Background Technology

[0002] A water turbine is a machine that uses the impact force of water to drive power generation equipment to produce hydroelectric power. Besides its application in large and medium-sized hydroelectric power stations, these machines are also used in smaller hydroelectric power generation projects, such as small reservoirs, small pumped storage power stations, and in tourism and educational settings. Many technical solutions for existing water turbines have been disclosed in Chinese patent applications. The most common water turbine is the one disclosed in Chinese patent CN201310074235.0, which includes at least two annular discs, a central shaft, spokes, and multiple blades. The central shaft is located at the center of the annular discs, and its axial direction is perpendicular to the radial direction of the annular discs. The water impacts the blades, driving the discs to rotate and thus driving the machinery or power generation equipment. This type of water turbine has a simple structure and is easy to manufacture, but its water utilization efficiency is relatively low. To improve efficiency, existing water turbines have various improved or modified designs, such as the high-efficiency water turbine disclosed in CN103670881A and CN118499172A. The publicly available water turbine runners and water turbines are complex designs and cannot provide a clear demonstration of the efficiency-enhancing process. Summary of the Invention

[0003] The purpose of this utility model is to provide a suspended bucket turbine.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: A suspended bucket turbine includes a frame, on which a central shaft is rotatably mounted. At least two impeller disks A and B are arranged radially outward at the central shaft. Multiple blades are fixedly connected between the two impeller disks A and B, and the multiple blades are evenly distributed circumferentially on the disks. Both disks are fixedly connected to the central shaft via multiple spokes. A bucket turbine A and a bucket turbine B are respectively arranged outside the impeller disks A and B. Both bucket turbines A and B are fixedly connected to the central shaft via multiple spokes. Multiple bucket shafts are fixedly connected between bucket wheel A and bucket wheel B. The bucket shafts pass through two blade wheel A and blade wheel B. The bucket shafts are parallel to the central axis. The multiple bucket shafts are evenly distributed on a circle with the central axis as the center. The buckets are rotatably connected and suspended on the bucket shafts. Two sets of tipping wheel mechanisms are fixedly installed at the lower part of the frame. The tipping wheel mechanism includes a wheel frame, on which tipping wheels are rotatably installed. One set of tipping wheel mechanisms is located between bucket wheel A and blade wheel A, and the other set of tipping wheel mechanisms is located between bucket wheel B and blade wheel B. The buckets interfere with the tipping wheels, and the tipping wheels drive the buckets to tilt.

[0005] Furthermore, the water bucket shaft is located circumferentially between two adjacent blades.

[0006] Furthermore, water passage holes or grooves are provided on both blade disk A and blade disk B between two adjacent blades.

[0007] Furthermore, multiple water trough devices are arranged radially inward on the blade. The water trough devices include a bottom ring fixedly connected to the spokes, and multiple baffles are fixedly connected to the bottom ring. Each baffle has a side plate, and the bottom of the side plate is closed with the bottom ring. A water trough is formed between two adjacent baffles, bottom plates, and side plates.

[0008] Furthermore, the water baffle is arc-shaped.

[0009] The positive and beneficial technical effects of this utility model are as follows: This water turbine can not only rotate by water impacting the blades, but the water after impacting the blades will also form a lateral gravity force to drive the water turbine to rotate after entering the water bucket and water tank. This can improve water utilization and power generation efficiency. It is suitable for use in small power plants, power generation demonstrations, science and education, tourism and other occasions, and can intuitively demonstrate the way to improve power generation efficiency.

[0014] To more fully explain the implementation of this utility model, implementation examples are provided. These implementation examples are merely illustrative of this utility model and do not limit its scope.

[0015] The present invention will be further explained in detail with reference to the accompanying drawings, in which the following references are made: 1: frame; 2: impeller disk A; 3: impeller disk B; 4: water bucket disk A; 5: water bucket disk B; 6: blade; 7: water bucket shaft; 8: water bucket; 9: arc-shaped plate; 10: wheel frame; 11: tipping wheel; 12: water tank; 13: bottom ring; 14: side plate; 15: water passage trough; 16: central shaft; 17: wheel spokes; 18: water outlet.

[0016] A suspended bucket turbine includes a frame 1, on which a central shaft 1 is rotatably mounted. Two blade disks A2 and B3 are arranged at the radially outer end of the central shaft. Multiple blades 6 are fixedly connected between the two blade disks A2 and B3. The multiple blades are evenly distributed in the circumferential direction of the disks. Both blade disks are fixedly connected to the central shaft by multiple spokes. The above is the basic structure of an existing water turbine.

[0017] A water bucket wheel A4 and a water bucket wheel B6 are respectively installed on the outer side of impeller disk A and blade disk B. Both water bucket wheels A and B are fixedly connected to the central shaft via multiple spokes 17. Multiple water bucket shafts 7 are fixedly connected between water bucket wheels A and B. The water bucket shafts are located circumferentially between two adjacent blades and pass through both blade disks A and B. In this embodiment, the water bucket shafts are fixedly connected to both blade disks A and B, which strengthens the impeller... The strength of the disc, the water bucket shaft is parallel to the central axis, and multiple water bucket shafts are evenly distributed on a circle with the central axis as the center. The water bucket 8 is rotatably suspended on the water bucket shaft. Two sets of tipping wheel mechanisms are fixedly installed on the lower part of the frame 1. The tipping wheel mechanism includes a wheel frame 10, on which tipping wheels 11 are rotatably installed. One set of tipping wheel mechanisms is located between the water bucket wheel disc A and the blade wheel disc A, and the other set of tipping wheel mechanisms is located between the water bucket wheel disc B and the blade wheel disc B. The water bucket interferes with the tipping wheel mechanism, and the tipping wheel drives the water bucket to flip.

[0018] Water passage holes or grooves are provided on blade disks A and B between two adjacent blades. Figure 4 The water tank 15 is shown, in Figure 1 , Figure 2, Figure 3 The diagram does not show a water passage hole or water passage groove. The water passage groove can also be a long water passage hole. The function of the water passage groove is to allow water to enter the water buckets on both sides after impacting the blades.

[0019] As a further optimization, multiple water trough devices are arranged radially inward on the blade. The water trough devices include a bottom ring 13 fixedly connected to the spokes, and multiple baffles are fixedly connected to the bottom ring. In this embodiment, the baffles are arc-shaped plates 9, and the baffles have side plates 14 on both sides (along the central axis). The bottom of the side plates is closed with the bottom ring, and an open water trough is formed between two adjacent baffles, bottom plates, and side plates. The open water trough can collect and store water after it impacts the blade, forming a lateral gravity. The lateral gravity can generate a torque that drives the central axis to rotate.

[0020] When this water turbine is in use, the water tank 12 (water source) is located at the top, and the outlet 18 is directly opposite the space between impeller disk A and impeller disk B. (Because the air at the bottom contracts when water flows down, adjusting the distance between the water turbine and the outlet ensures that the water at the outlet flows between impeller disk A and impeller disk B. The blades generate torque under the action of the water's scouring force, driving the central shaft to rotate. The water that flows over the blades is partially collected in the water buckets and tanks on both sides. The weight of the water buckets increases, creating lateral gravity, and the water in the tanks also creates lateral gravity. Both of these lateral gravity forces can form...) The torque generated by the central shaft rotation improves water utilization efficiency. When the bottom of the water bucket rotates past the tipping wheel, it interferes with the wheel, driving the water bucket to rotate around its axis and empty the water. Similarly, when the open trough rotates to the bottom, its opening faces downwards, and water flows out automatically. Therefore, the water buckets and open troughs are empty during the upward movement and do not create resistance to the central shaft. The water bucket wheel A, water bucket wheel B, and water buckets in this turbine experience relatively low stress during use and can all be made of lightweight materials, resulting in a limited increase in overall weight but a significant increase in water utilization.

[0021] After a detailed description of the embodiments of this utility model, those skilled in the art will clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent applications. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the scope of the technical solution of this utility model, and this utility model is not limited to the embodiments of the examples given in the specification.
