Horizontal turbine

Abstract

A horizontal water turbine includes a main body mounted on a base, with its diameter direction parallel to a water surface. A blocking structure is positioned on the base, with two sides defined as a blade-receiving section and a blade-releasing section. When the blade of the turbine structure rotates into contact with the blade-receiving section, the blade folds upward into a first position. As it rotates to the blade-releasing section, the blade leaves the blocking structure and unfolds downward into a second position. This design allows the blade to shift between the first and second positions, ensuring optimal utilization of water flow kinetic energy under varying flow conditions, effectively reducing water resistance and enhancing energy conversion efficiency.

Description

[Technical Field]

[0001] This invention relates to a hinged water turbine, and more particularly to a horizontal water turbine that can effectively reduce water flow resistance, thereby reducing energy loss. [Previous Technology]

[0002] Traditional water turbine designs often rely on fixed blades. When water flows onto the blades, significant resistance is generated, leading to energy loss. This resistance problem is particularly pronounced in environments with low flow velocities or frequent changes in flow direction. This not only reduces energy conversion efficiency but also accelerates blade wear and increases maintenance costs. Furthermore, the operating principle of traditional horizontal water turbines is to use forward-flowing water to drive the blades to rotate and output kinetic energy. However, horizontal water turbines are restricted by the direction of water flow, generating half the resistance, further reducing the efficiency of kinetic energy output and causing additional energy loss.

[0003] Therefore, how to further reduce the resistance of water turbines in the frequently changing water flow environment, thereby improving energy conversion efficiency, reducing blade wear and reducing manufacturing and maintenance costs, has become a problem to be solved. [Summary of the Invention]

[0004] Based on the above deficiencies, the purpose of this invention is to provide a horizontal water turbine that can effectively reduce water flow resistance, thereby reducing energy loss.

[0005] According to the purpose of the present invention, a horizontal water turbine is provided, having a main body disposed on a base, the diameter direction of the main body being parallel to a water surface, the main body comprising a plurality of blade structures, characterized in that the base has a positioning part and a blade receiving part, a blocking structure disposed within the blade receiving part, the two sides of the blocking structure being defined as a blade retracting part and a blade lowering part, when a blade of each blade structure contacts the blade retracting part, the blade folds upward along the surface of the blade retracting part to a first position; when the blade of each blade structure rotates to the blade lowering part, the blade leaves the blocking structure and unfolds downward to a second position.

[0006] The main body also includes a rotating shaft vertically disposed on a positioning seat, the positioning seat being disposed on the positioning part, and the blade structures being disposed in the blade receiving part and connected to the rotating shaft through a connecting component.

[0007] The paddle receiving part has an inclined surface.

[0008] The blocking structure is a U-shaped baffle or a trapezoidal block.

Implementation Method

[0009] To clearly illustrate the specific embodiments, structure, and effects achieved by the present invention, embodiments are provided and described in conjunction with the drawings as follows:

[0010] Please refer to Figures 1 and 2, which illustrate a horizontal water turbine having a main body 10 and a base 20. The base 20 has a positioning part 201 and a blade receiving part 202. The main body 10 includes a rotating shaft 111, a plurality of blade structures 12, and the rotating shaft 111 is vertically disposed on a positioning seat 112. The positioning seat 112 is disposed within the positioning part 201. The blade structures 12 are disposed within the blade receiving part 202 and are connected to the rotating shaft 111 through a connecting component 15. Each blade structure 12 has a blade and a blade shaft. The blades are fan-shaped blades, but are not limited thereto. The present invention mainly drives the rotating shaft 111 to rotate by driving the blade structures 12 through water flow power.

[0011] Further explanation: The horizontal turbine also has an output gear set (not shown) connected to a rotating shaft 111. The output gear set transmits the rotational kinetic energy of the horizontal turbine to a generator (not shown) to achieve energy conversion.

[0012] In an embodiment of the present invention, the main body 10 is disc-shaped, and the diameter direction of the main body 10 is parallel to the water surface W. When the water flow pushes the impeller structure 12, it drives the rotating shaft 111 to rotate counterclockwise 360 ​​degrees. The base 20 has a blocking structure 21 disposed in the impeller receiving portion 202. Please refer to Figure 3. The blocking structure 21 is a trapezoidal block. The two sides of the blocking structure 21 are defined as a blade-retracting portion 211 and a lower blade-retracting portion 212, respectively. The blade-retracting portion 211 is an inclined surface. When the blades of each impeller structure 12 come into contact with the blade-retracting portion 211, the blades will fold upward along the surface of the blade-retracting portion 211 to a first position. When the blades of each impeller structure 12 rotate to the lower blade-retracting portion 212, the blades leave the blocking structure 21 and unfold downward to a second position. In other embodiments, the blocking structure 21 can be a U-shaped baffle, but it is not limited thereto. The blocking structure 21 is designed to reduce water flow resistance and increase kinetic energy conversion efficiency.

[0013] To further explain, when the blade is in the first position, only the tail end of the blade contacts the water surface W, allowing the water flow to smoothly slide over the blade, reducing the water flow resistance caused by frontal impact, and making the rotation of the rotating shaft 111 smoother; when the blade is in the second position, the blade surface is perpendicular to the water surface, maximizing the contact area between the blade and the water flow, so as to maximize the kinetic energy of the water flow.

[0014] Please refer to Figure 2, which is a schematic diagram of a horizontal turbine installed in a waterway. The hollow arrows in the figure indicate the direction of water flow, and the solid arrows indicate the rotation direction of the main body 10. This invention uses the counter-clockwise rotation of the main body 10 as an example. The blades of the horizontal turbine are driven to rotate by the water flow. When the water flows through the blade retractor 211 of the horizontal turbine, the energy of the water flow is effectively converted into kinetic energy to drive the blades to rotate, causing the rotating shaft 111 of the horizontal turbine to generate rotational power. As the rotating shaft 111 rotates, the blades sequentially enter the lower blade section 212, and the blades gradually unfold to fully receive the driving force of the water flow, further increasing the efficiency of the horizontal turbine. The blade retractor 211 and the lower blade section 212 of the blocking structure 21 form an optimal water flow guide, allowing the water flow to move smoothly on the blade surface without generating turbulence or eddies, further reducing the resistance experienced by the blades. This invention not only improves the power output of the horizontal turbine but also adapts to changes in water flow speed and flow rate.

[0015] Please refer to Figure 4 for another embodiment of the horizontal water turbine of the present invention installed in a waterway. Users can stack multiple horizontal water turbines according to the water depth. In this embodiment, a central shaft 1111 is inserted into the waterway. The function of the central shaft 1111 is the same as that of the aforementioned rotating shaft 111, and the length of the central shaft 1111 is greater than the water depth. Multiple horizontal water turbines are sequentially fixed to the central shaft 1111 from top to bottom. Furthermore, the number and distribution of the water turbines can be flexibly adjusted according to the actual water depth conditions, thereby improving the applicability and energy conversion efficiency of the hydropower generation equipment.

[0016] Further explanation: In this embodiment, the upper and lower horizontal turbines are connected by a water pipe 30. One end of the water pipe 30 is located at the blade retractor 211 of the upper horizontal turbine, and the other end is located at the blade shearer 212 of the lower horizontal turbine. This allows water to flow through the upper horizontal turbine and then be guided to the lower horizontal turbine via the water pipe 30. This not only effectively utilizes water flow energy and reduces energy loss, but also avoids reducing the driving efficiency of the lower turbine due to water flow dispersion. Through the flow guiding function of the water pipe 30, the upper and lower horizontal turbines can operate collaboratively to form a continuous and efficient power generation system, further improving the overall structural stability and energy conversion efficiency. Furthermore, the configuration of the water pipe 30 can be optimized and adjusted according to water flow velocity and flow rate to ensure stable and efficient operation of the system in different operating environments.

[0017] Through the vertical arrangement of multiple horizontal turbines, the water flow can drive the blades of each layer of horizontal turbines, thereby making full use of the kinetic energy of the water flow at different depths and further improving the overall efficiency. This stacked arrangement design not only maximizes the power output of the turbines in a limited water area, but also adapts to changes in different water flow speeds, enabling the present invention to have excellent operating efficiency under various water flow conditions.

[0018] In other embodiments, multiple horizontal turbines can be arranged in parallel on both sides of the waterway, with multiple horizontal turbines on each side, and the turbines arranged sequentially along the water flow direction. Each horizontal turbine has a certain spacing, allowing water to flow smoothly through each turbine and effectively drive its blades to rotate. This parallel configuration allows water to simultaneously drive multiple sets of horizontal turbines on both sides of the waterway, thereby improving the utilization efficiency of water kinetic energy. The parallel arrangement not only provides a symmetrical kinetic energy distribution but also helps enhance the stability of the turbine system and reduce the instability effects caused by water flow impact. Furthermore, the number and arrangement density of the horizontal turbines can be adjusted according to the width of the waterway and the water flow velocity to adapt to different water flow conditions and improve overall efficiency and adaptability.

[0019] The horizontal turbine of the present invention, by providing a blocking structure 21 on the base 20, allows the blades to change between a first position and a second position, maximizing the kinetic energy utilization of the water flow under different water flow conditions, and ensuring that water flow resistance is effectively reduced and kinetic energy conversion efficiency is enhanced without damaging any ecological environment. Furthermore, the present invention can also be used in waterways of different depths and widths through multi-layer vertical stacking or parallel arrangement on both sides, further improving overall power generation efficiency. It maintains stable output even in environments with large variations in water flow velocity or flow rate, giving the present invention wider applicability and stability, thereby achieving higher energy conversion efficiency and expanding the application range of the turbine.
