Abstract

The present invention provides a reciprocating hydroelectric mechanism, comprising: a sliding rod, pivoting at least one propeller airfoil which generates lift force to drive the sliding rod in linear motion by the fluid flow force, thus to drive the power generating device to generate electricity with the rotation of the transmission rod and the rotation rod rotate. The lift force is generated by the fluid flow through said airfoils, which push the sliding rod to move in one direction. Therefore, when the sliding rod moves to the left or right dead point, the steering mechanism adjusts the angle of said airfoils to let the airfoils generate a lift force in the opposite direction by fluid flow, causing the sliding rod moves in another direction, until the sliding rod moves to another dead point that makes the airfoils turn again and move backwards. It will generate a reciprocating circular motion, thus let the transmission rod and the rotation rod continuously rotates to drive the power generating device to generate electricity. There could be a large gap between said airfoils, so that small debris can easily flow by, without affecting the linear motion of the sliding rod. The steering motion of said airfoils also prevents the debris from entangling the said airfoils, avoiding a reduction in propulsion. A swing mechanism can rotate the sliding rod to let said airfoils leave the water, so as to let large debris which remains in water can pass by, and then let said airfoils inserted into fluid flow to generate electricity as described above. The feature can also be used at high tide flooding: only need to rotate said airfoils away from the fluid by swing mechanism can prevent the present invention from being damaged by flooding. As a result, the present invention can be applied to low-head hydroelectric power in water pipes: high efficiency, small size, free-flowing, with functions of flood prevention and easy maintenance.

Description

Reciprocating hydroelectric power generation mechanism

The present invention provides a reciprocating hydroelectric power generation mechanism, in particular a propulsion wing pivoted on a sliding rod, so that the propulsion wing can be lifted by the flow of the fluid to drive the linear motion, and when the sliding rod moves to the left or right At the dead point, the steering mechanism will adjust the angle of the propulsion wing and move in a straight line in the opposite direction; this will repeatedly drive the generator to generate electricity.

According to, hydroelectric power uses the potential energy of the water head to generate kinetic energy when it flows, so as to promote the rotation of the turbine of the power generation device, thereby driving the generator to generate electricity.

Most of the hydroelectric power generations are large-scale hydropower generation. The conditions for large-scale hydropower generation include factors such as head and flow rate. In response to various conditions, the types of hydropower generators used include: impulse turbines, reaction turbines Among them, impulse turbines include Pelton, Turgo, and Cross Flow models, reaction turbines include Deriaz, Vertical Francis, and Horizontal Francis models, and reaction turbines include Propeller rotary turbines , Kaplan rotary turbines, Bulb bulb turbines and S-type tubular flow turbines.

According to the Taiwan Electric Power Co., Ltd.’s Implementation Measures for the Acquisition of Small Hydroelectric Power, the defined capacity is less than 20,000 kilowatts, and the United Nations and the World Bank have further defined that small hydroelectric power is the capacity greater than 1,000 kilowatts and less than 10,000 kilowatts. Mini hydropower has a capacity greater than 100 kW and less than 1,000 kW, while micro hydropower has a capacity less than 100 kW. It is obvious that the channel head of micro hydropower is very small, which is the same as traditional large hydropower. The high-head conditions are not met;

The traditional micro-hydraulic channel generators all use rotating waterwheels, such as China’s "LCS Stream Hydropower System", which is suitable for installation in low-head and low-flow low-slope (above 3/1,000) channels or canals The applicable flow rate is 1.5 to 5 meters per second, and the applicable flow rate is 25 to 30 seconds cubic meters. The construction cost is about 100,000/cm; however, the traditional micro-hydropower channel generator has the blade direction The water flow plane of the channel is parallel. Therefore, each blade is almost equal to the width of the channel. Therefore, if there is debris in the channel, such as driftwood, sand or garbage, it will be stuck on the blades, which will affect the rotation of the blades. If it is set, it will cause damage to the blade; in addition, when the blade enters the water, it will generate resistance due to impact. When the specific rotation occurs, the blade can only play its role when it enters the water, so it actually produces The cost of electricity is high, and the effect is not good. Moreover, the traditional micro-hydro channel generator is very large, and it is extremely difficult to transport, erect and maintain. Therefore, it is impossible to directly remove the water surface during the flood season. Towing a large crane will consume a lot of time, manpower and money costs; and its erection cost is extremely high, but the power generation efficiency is not obvious, so its practicality is still greatly limited.

In view of this, our inventors devoted themselves to further research on micro-hydroelectric power generation, and proceeded to develop and improve, hoping to develop a better invention to solve the above problems, and after continuous testing and modification, the present invention came out.

The purpose of the present invention is to solve the aforementioned problems. In order to achieve the above objectives, our inventors provide a reciprocating hydroelectric power generation mechanism, which includes:

A sliding rod, at least one propulsion wing, a steering mechanism and a power generating device;

Wherein, the sliding rod is used to be erected in a flow channel with fluid, the sliding rod is arranged and pivoted with at least one propulsion wing in the vertical direction of the axial direction; the sliding rod defines a movable range in the axial direction, and The two ends of the sliding rod axially define a left dead center and a right dead center respectively at the two ends of the movable range;

The propulsion wing has a first lift position and a second lift position. When the propulsion wing is at the first lift position, it is lifted by the flow of the fluid to drive the sliding rod to move to the left, and in the first lift position. In the second lift position, the lift is generated by the flow of the fluid and drives the slider to move to the right;

In this way, the fluid pushes the propulsion wing to generate lift, which in turn drives the sliding rod to move linearly, thereby enabling the power generating device to generate electricity.

The steering mechanism is pivotally connected to the propulsion wing, and when the sliding rod moves to the left dead center, the The rotation of the propulsion wing is adjusted to the second lift position, and when the slider moves to the right dead center, the rotation of the propulsion wing is adjusted to the first lift position; in this way, the propulsion wing can drive the slider to produce Linear reciprocating motion, the power generating device is connected to the sliding rod, so the reciprocating motion of the sliding rod can drive the power generating device to generate electricity.

There may be large gaps between single or plural propulsion wings, so that small debris can easily flow through, and the propulsion wing is steered by the steering mechanism, which makes it difficult for debris to catch the propulsion wing and reduce the thrust.

In one embodiment, the sliding rod can be erected by a frame system, and the sliding rod is further fixedly provided with a rotating device at one end opposite to the power generating device, so that the sliding rod is synchronously rotated on the rotating device, the The rotating device is eccentrically arranged with a rotating handle relative to one end of the connecting rod; when there is no large debris in the water, the propelling wing can be swung down to deepen the water and perform reciprocating motion as described above to generate electricity. If there is a large debris , The rotating device can be rotated by the handle to swing the propulsion wing up and off the water surface through the slide bar, so that the sundries can flow through; in the flood season, it is only necessary to swing the propulsion wing up and off the water surface as mentioned above. It may affect the water flow or cause damage to the present invention.

As a result, the present invention can have extremely high performance and no noise from the impact of the blades on the water surface, and the reciprocating motion of the propulsion wing, the steering mechanism and the rotating device that make the propulsion wing swing, the overall composition is quite coordinated, so the present invention is assembled The space required is small; therefore, the present invention can be applied to rivers and channels for sewage discharged from related factories to achieve the effect of power generation.

The frame is provided with two shaft tubes, and a linear bearing unit is respectively provided in the shaft tubes, and the sliding Both ends of the rod are axially slidably connected in the linear bearing unit; in one embodiment, the two ends of the sliding rod are respectively provided with a sliding block, and the sliding block is axially slidingly connected to the linear bearing unit. In the linear bearing unit;

The length of the transmission rod is Larger than the rotating rod, the rotating rod is pivoted to a shaft at one end opposite to the transmission rod, and the shaft is connected to the power generating device; thereby, when the connecting rod moves axially, the transmission will be driven The rod and the rotating rod rotate around the shaft and drive the shaft to rotate, so as to drive the power generating device through the rotation of the shaft to generate electricity.

According to the above-mentioned reciprocating hydroelectric power generation mechanism, the shaft is further equipped with a flywheel to make the shaft generate rotational inertia in a rotation direction, so that the rotation direction of the transmission rod, the rotating rod and the shaft Consistent, and not because the sliding rod is parallel to the driving rod and the rotating rod, the reverse rotation of the driving rod and the rotating rod will reduce the power generation efficiency, and the output torque and speed will be more uniform.

Regarding the technical means of our inventors, several preferred embodiments are described in detail below in conjunction with the drawings to provide a thorough understanding and approval of the present invention.

Please refer to Figures 1 to 3 first, the present invention is a reciprocating hydroelectric power generation mechanism, which includes:

A slide bar 1, which is used to set up a flow channel 2 with a fluid F. In a specific embodiment, the flow channel 2 can be a river or a channel, and the fluid F is water flowing in it; the slide bar 1. At least one propulsion wing 3 is arranged and pivoted at intervals in the vertical direction of the axial direction; the sliding rod 1 defines a movable range in the axial direction, and the two ends of the sliding rod 1 in the axial direction are respectively at the two ends of the movable range A left dead center P1 and a right dead center P2 are defined; the propulsion wing 3 has a first lift position and a second lift position, and when the propulsion wing 3 is at the first lift position, it is subjected to the flow of fluid F The force generates lift to drive the slide bar 1 to move to the left, and when in the second lift position, the flow force of the fluid F generates lift to drive the slide bar 1 to move to the right;

A steering mechanism 4, which is pivotally connected to the propulsion wing 3, and when the sliding rod 1 moves to the left dead center P1, the propulsion wing 3 is rotated and adjusted to the second lift position, and the sliding When the rod 1 moves to the right dead center P2, the propulsion wing 3 is rotated and adjusted to the first lift position; and

A power generating device 5 which is connected to the slide bar 1 and generates power by the movement of the slide bar 1. In one embodiment, the power generating device 5 can be a micro-generator of 10 kilowatts to 100 kilowatts.

With regard to the erection of the sliding rod 1, in one embodiment, a frame 6 is mounted on the flow channel 2. The frame 6 is provided with two shaft tubes 61, and a linear bearing unit 62 is respectively provided in the shaft tubes 61 , And the two ends of the sliding rod 1 are axially slidably connected in the linear bearing unit 62, so that the sliding rod 1 can perform linear reciprocating smoothly; in a preferred embodiment, the sliding rod 1 The two ends of the two ends are further provided with a sliding block 11 respectively. The sliding rod 1 is axially slidably connected in the linear bearing unit 62 by the sliding block 11; this facilitates the connection of other components through the sliding block 11;

First of all, in terms of the linear reciprocating motion of the slide bar 1, the water flow in the flow channel 2 has a single flow direction due to the height of the head, and the propulsion wing 3 is arranged in a wing shape, therefore, at a rotation angle , The specific shape and angle setting of the lift that can be received by water flow are conventional technology, and the present invention does not limit the specific shape of the propulsion wing 3, so it will not be repeated here; and the lift force is as mentioned above, and As shown in Figures 1 and 2, when the propulsion wing 3 is in the first lift position, as shown in Figure 4, the lift is generated by the flow force of the fluid F and drives the slider 1 to the left When the sliding rod 1 moves to the left dead center P1, the propulsion wing 3 will be rotated and adjusted by the steering mechanism 4 to the second lift position, as shown in Figure 5, the propulsion wing 3 is subject to fluid F The current force generates lift and drives the slider 1 to move to the right;

There are many ways to steer the propulsion wing 3, which can be achieved by using related mechanical structures. In this embodiment, the steering mechanism 4 includes two limiting elements 41, 41', and the limiting element 41 The distance between, 41' is smaller than the movable range. A connecting rod 42 is provided between the limiting elements 41 and 41'. The connecting rod 42 is parallel and driven by the sliding rod 1, and the connecting rod 42 is pivoted There are corresponding adjustment rods 43 pivotally connected to the propulsion wing 3; and the connecting rod 42 moves from the middle of the limiting elements 41, 41' to the left end of the connecting rod 42 contacting the limiting element 41 at the left end At this time, the position of the slide bar 1 is the left adjustment point P3, and the connecting rod 42 moves from the middle of the limiting element 41, 41' to the right end of the connecting rod 42 contacting the limiting element 41' at the right end. The position of the sliding rod 1 is the right adjustment point P4; in order to prevent the connecting rod 42 from hitting the limiting elements 41, 41' for a long time and causing damage, and to avoid noise during collisions, in one embodiment, the connecting rod 42 has two end sections There are also abutting portions 44, 44' corresponding to the limiting elements 41, 41' respectively, and as shown in Figure 4, the connecting rod 42 is formed by the limiting elements 41, 41' The position of the slide bar 1 when the abutting portion 44 moved to the left end contacts the limiting element 41 at the left end in the middle is the left adjustment point P3, and the connecting rod 42 is defined by the limiting elements 41, 41' The position of the slide bar 1 when the stopper 44' moved to the right end in the middle contacts the limit element 41' at the right end is the right adjustment point P4;

Thereby, as shown in Figure 5, it is the position of the slide bar 1 at the left adjustment point P3. At this time, since the distance between the limiting elements 41, 41' is smaller than the movable range, the slide bar 1 It can still move to the left due to the lift generated by the propulsion wing 3 at the first lift position, as shown in Figure 6, so the connecting rod 42 of the time is supported by the limiting element 41 on the left and cannot move. The sliding rod 1 can continue to move to the left, so the adjusting rod 43 will be pulled by the sliding rod 1 and the propelling wing 3 to gradually rotate the angle of the propelling wing 3, and during the rotation of the propelling wing 3, When the wing 3 is parallel to the direction of the water flow, the pivoting positions of the adjusting rod 43 and the connecting rod 42, and the pivoting positions of the adjusting rod 43 and the propelling wing 3 correspond to each other, and the distance between the two is the closest. Therefore, in one embodiment, the adjusting rod 43 may be a segmented telescopic rod; and when the propulsion wing 3 is parallel to the direction of the water flow, although the propulsion wing 3 does not generate lift at this time, the connecting rod 42 faces the left The inertial force of the moving side can help the connecting rod 42 move to the left to continuously adjust the angle of the propelling wing 3 until it reaches the left dead center P1, so that the propelling wing 3 is adjusted by the adjustment rod 43 as described above. Is the second lift position, so that the propelling wing 3 is lifted by the flow force of the fluid F to drive the slider 1 to move to the right; and when the slider 1 moves to the right adjustment point P4, it will be as described in the previous principle, And as shown in Figures 7 and 8, gradually moving to the right dead center P2, so that the propelling wing 3 is pulled by the adjusting rod 43 to be adjusted to the first lift position, and then the sliding rod 1 is moved to the left, and so on. It can achieve linear reciprocating motion of the slide bar 1.

The linear reciprocating motion of the slide bar 1 can be used to drive the power generating device 5 to generate electricity. For the linear reciprocating motion to cause the power generating device 5 to generate power, it is a conventional technology, and in this embodiment, as shown in Figs. 4-7 As shown, the power generating device 5 generates electricity by converting the linear reciprocating motion of the sliding rod 1 into a circular rotation motion. Specifically, for example, in one embodiment, the sliding rod 1 is pivoted with a transmission rod 12 at one end. , The transmission rod 12 is pivoted with a rotating rod 13 at one end opposite to the connecting rod 42. The length of the transmission rod 12 is greater than the rotating rod 13, and the rotating rod 13 is pivoted at the end opposite to the transmission rod 12 A shaft 14 is connected to the power generating device 5; when the connecting rod 42 moves axially, the pivot point of the shaft 14 and the rotating rod 13, as well as the sliding rod 1 and the transmission The linear movement between the pivot points of the rod 12, in line with the difference in length between the transmission rod 12 and the rotating rod 13, will cause the transmission rod 12 and the rotating rod 13 to rotate in one direction, and rotate around the shaft 14, thereby driving The shaft 14 rotates to drive the power generating device 5 to generate electricity through the rotation of the shaft 14;

And as mentioned above, because when the transmission rod 12 and the rotating rod 13 are parallel, as shown in Figures 6 and 8, the pivot point of the aforementioned shaft 14 and the rotating rod 13, as well as the sliding rod 1 and the transmission rod 12 The linear movement between the pivot points does not necessarily cause the transmission rod 12 and the rotating rod 13 to rotate in the original rotation direction. Therefore, by arranging a flywheel 7 on the shaft 14 to make the shaft 14 generate in a rotation direction The inertia of rotation, by which the transmission rod 12 and the rotating rod 13 are parallel and subjected to the linear movement force between the aforementioned pivot points, the inertial force can induce the transmission rod 12 and the rotating rod 13 to rotate in the original direction of rotation, and The output torque and rotation speed are more uniform, so as to achieve the effect of stable power generation. In addition, the inertia of the shaft 14 rotation can also provide the force of the aforementioned propulsion wing 3 to move in the same direction when parallel to the direction of the water flow, thereby overcoming the present invention. When the propulsion wing 3 is parallel to the water flow direction, no lift is generated, or the propulsion wing 3 moves parallel to the water flow direction to cause the left dead center P1 or the right dead center P2. During the process, the propulsion wing 3 produces a reverse lift on the water flow, causing the slide bar 1 Phenomenon of inability to move; and as far as the specific mechanism of the flywheel 7 is concerned, since it is a conventional component and is applied to the present invention, its structure and principle of action are not repeated here.

In order to prevent the excessive speed of the shaft 14 from affecting the performance of the power generating device 5, or causing damage to the power generating device 5, in one embodiment, the shaft 14 can be connected to a transmission device 8 at one end. The speed change device 8 can be a reduction gear set, which is a conventional component and is applied to the present invention, so its structure and working principle are not repeated here. The power generating device 5 is further provided with a transmission shaft 51, the speed change device 8 is connected to one end of the shaft 14 with the transmission shaft 51; when the shaft 14 rotates, it is transmitted to the transmission shaft 51 at a variable speed through the transmission device 8, so that the transmission shaft 51 rotates to drive the transmission shaft 51 The power generating device 5 generates electricity, and can coordinate with the design rotation speed of the power generating device 5 to achieve the best efficiency.

As a result, the present invention can be applied to a wide range of power generation, and can be applied to power generation under the conditions of low head height and/or flow. Therefore, it can be applied to rivers and the channels of sewage discharged from related factories to achieve The effect of power generation, and the overall volume of the present invention is small, easy to install and maintain, which can improve the overall applicability of the present invention.

As mentioned above, since the propulsion wings 3 of the present invention are arranged in parallel and spaced apart, if there are small debris in the water flow, they can flow through the gaps between the propulsion wings 3, and the propulsion wings 3 will rotate at an angle. When the sundries are not easily caught on the propelling wing 3, the lift force is reduced; and when there are large sundries in the water flow, it is not eliminated. Therefore, in one embodiment, as shown in Figures 1 to 4 As shown, the sliding rod 1 is further fixedly provided with a rotating device 9 at one end opposite to the power generating device 5, so that the sliding rod 1 is synchronously rotated on the rotating device 9, and the rotating device 9 can pass through a motor, or It can be a turntable, and the rotating device 9 is provided with a rotating handle 91 eccentrically relative to the end of the connecting rod 42 to automatically or manually rotate the sliding rod 1; and because the sliding rod 1 is connected with a connecting rod 42 and a propulsion wing 3. Therefore, the connecting rod 42 and the propulsion wing 3 will also swing with the rotation of the slide bar 1, so that the propulsion wing 3 can be moved out of the water surface, so that large debris can pass along with the flowing water. In addition, during the flood season, it is also The propulsion wing 3 can be placed out of the water to prevent the flood discharge from being hindered, and the invention can also be prevented from being damaged by floods; in one embodiment, the invention can be fully erected on the frame 6 so that the rotating device 9 can rotate At this time, the present invention can be rotated as a whole to keep away from the flow channel 2 to prevent the whole present invention from being damaged by flooding.

In summary, the technical means disclosed in the present invention can effectively solve conventional problems and achieve the expected purpose and effect. It has not been seen in publications, has not been used publicly, and has long-term progress before application. The patent law claims that the invention is correct.
