Description

Technical Field

[0001] The present invention relates to the technical field of hydroelectric power generation devices, and in particular to a kinetic energy conversion device of a hydroelectric generator. Background Art

[0002] Hydropower is a renewable energy utilization method that converts the kinetic energy of water into mechanical energy and then further into electrical energy. With the increasing demand for renewable energy, hydropower technology has received widespread attention and has been applied in many fields.

[0003] At present, traditional hydroelectric power generation usually relies on fixed water flow direction and speed, resulting in certain limitations on power generation efficiency under changing water flow conditions. For example, application publication number CN118686726A discloses a kinetic energy conversion hydroelectric generator, which specifically discloses that the generator is set on the beach and connected to the generator set through a transmission shaft; it includes a support frame, a transmission shaft on the support frame, and the transmission shaft is rotatably connected to the support frame; the two transmission shafts form a plane parallel to the beach, sprockets are synchronously installed at both ends of the two transmission shafts, and the two transmission shafts are synchronously connected through a chain; blades are installed on the chain; auxiliary paddles are installed at both ends of the transmission shaft, and the paddles rotate coaxially with the sprockets; a deflector is placed in front of the auxiliary paddle on the beach, and its function is to prevent the front waves from impacting the blades below the auxiliary paddle, and at the same time guide the upper falling water flow to impact the blades below, so that the blades absorb water flow in both the front and rear directions.

[0004] Although the above-mentioned hydroelectric generator can convert kinetic energy under changing water flow conditions, there are still some shortcomings. For example, the hydroelectric generator uses water flow to impact the blades installed on the chain, thereby changing the moving position of the blades and driving the sprocket to rotate to generate electricity. However, there is a height difference between the transmission shafts at the front and rear ends. When the water flow impacts the blades, the position of the blades after rotation is not at the bottom of the rotating shaft. The auxiliary paddle and the deflector may not be able to provide the power for the blades to rotate upward, which may cause the sprocket to be unable to rotate continuously, resulting in inefficient and unstable power generation.

[0005] Therefore, it is necessary to make further improvements to the prior art. Summary of the invention

[0006] In view of the problems existing in the above-mentioned prior art, the object of the present invention is to provide a kinetic energy conversion device for a hydroelectric generator, which provides paddles on both sides of a transmission belt that are opened and closed by the push of the water flow, so that the paddles on both sides can continuously and stably convert the kinetic energy of the water flow into mechanical energy that can be used for power generation after being impacted by the water flow; when the paddles on one side are unfolded, the paddles on the other side can be closed in coordination to reduce the resistance generated when the water flow pushes the blades to unfold.

[0007] In order to achieve the above object, the technical solution of the present invention is:

[0009] Furthermore, two bearings are provided between each of the fixed shafts and the sleeve, and the two bearings are respectively provided at the upper and lower ends of the sleeve.

[0010] Furthermore, a plurality of the blades are evenly distributed on the surface of the transmission belt, and the spacing between each of the blades is the same.

[0011] Furthermore, the paddle is connected to the transmission belt via a hinge device.

[0012] Furthermore, the hinge device comprises a hinge connection seat fixedly arranged on the surface of the transmission belt and a hinge connection rod inserted in the hinge connection seat, and one end of the paddle is movably connected to the hinge connection rod.

[0013] Furthermore, one end of the support block is fixedly connected to the paddle, and the other end thereof extends downward and can abut against the surface of the transmission belt after the paddle is pushed by the water flow.

[0014] Furthermore, two bearings are provided between each of the fixed shafts and the sleeve, and the two bearings are respectively provided at the upper and lower ends of the sleeve.

[0015] Furthermore, baffles for preventing the transmission belt from moving up and down are respectively provided at the upper and lower ends of the sleeve.

[0016] Furthermore, the diameters of the two baffles are greater than the diameter of the sleeve.

[0017] Furthermore, the first blade can be kept in the unfolded state by replacing the support block by only setting a connecting belt on the right side of each first blade, and the second blade can be kept in the unfolded state by only setting a connecting belt on the left side of each second blade. Through the above arrangement, after the first blade and the second blade are impacted by the water flow, the connecting belt can tighten and fix the first blade or the second blade after it is unfolded to a certain angle, so that the first blade or the second blade can maintain the unfolded state under the impact of the water flow.

[0035] The invention is further described below in conjunction with the accompanying drawings and specific embodiments. The following description is only exemplary and does not limit the protection scope of the invention.

[0036] Embodiment 1:

[0037] like Figure 1-Figure 6 As shown, a kinetic energy conversion device of a hydroelectric generator. In this embodiment, the kinetic energy conversion device of the hydroelectric generator is used to convert the kinetic energy of water flow into mechanical energy.

[0038] It comprises a support frame 1, fixed shafts 2 vertically arranged on both sides of the support frame 1, sleeves 3 sleeved on each fixed shaft 2 and rotatably connected to the fixed shaft 2, and a transmission belt 4 for connecting the two sleeves 3;

[0039] A gear 5 is also provided at one end of each sleeve 3, and the gear 5 can be connected to an external power generation device; in this embodiment, when the sleeve 3 rotates, it can synchronously drive the gear 5 to rotate, so that the mechanical energy generated by the rotation of the gear 5 can be converted into electrical energy through the external power generation device.

[0040] like Figure 3-Figure 4As shown, a plurality of paddles 6 that can be automatically opened and closed by the water flow are hinged on the surface of the transmission belt 4. The paddles 6 include a first paddle 61 arranged on one side of the transmission belt 4 and a second paddle 62 arranged on the other side of the transmission belt 4. Support blocks 7 are respectively arranged on the left side of the first paddle 61 and the right side of the second paddle 62. The support blocks 7 can be used to maintain the deployment angles of the first paddle 61 and the second paddle 62. In this embodiment, when the water flow flows from right to left and pushes the first paddle 61, the first paddle 61 can be turned over and abutted with the transmission belt 4 by the support block 7 arranged on its left side to form an deployment state. At the same time, since the support block 7 on the second paddle 62 is arranged on its right side, after the water flow pushes the water-facing surface of the second paddle 62, the support block 7 on the second paddle 62 cannot abut with the transmission belt 4, so that the second paddle 62 is in a closed state under the push of the water flow. In order to make the first paddle 61 more efficient in utilizing water energy after being deployed, the angle of the first paddle 62 after being deployed is about 90 degrees.

[0041] In this embodiment, the kinetic energy conversion device of the hydroelectric generator is used in a river or a beach;

[0042] Among them, Figure 3-Figure 4 As shown, when the water flows from right to left, the water pushes the first paddle 61 to be in an expanded state; the first paddle 62, pushed by the water, drives the two sleeves 3 and the gear 5 to rotate synchronously through the transmission belt 4, thereby converting the kinetic energy of the water into mechanical energy for power generation; at this time, the second paddle 62 located on the other side of the transmission belt 4 is in a closed state under the push of the water, so as to reduce the resistance generated by the water pushing the first paddle 61.

[0043] When used on the beach, if the water flows from left to right (seawater backflow generated by the tide), as shown in 5, the water flow pushes the second paddle 62 to be in an unfolded state; the second paddle 62, driven by the water flow, drives the two sleeves 3 and the gear 5 to rotate synchronously through the transmission belt 4, thereby converting the kinetic energy of the water flow into mechanical energy for power generation; at this time, the first paddle 61 is in a closed state under the push of the water flow, so as to reduce the resistance generated by the water flow pushing the second paddle 62.

[0044] like Figure 2 As shown, two bearings 8 are provided between each fixed shaft 2 and the sleeve 3, and the two bearings 8 are respectively provided at the upper and lower ends of the sleeve 3. Through the above arrangement, the sleeve 3 provided on the fixed shaft 2 can rotate along the axial direction of the fixed shaft 2; in addition, the two bearings 8 are respectively provided at the upper and lower ends of the sleeve 3, which can also make the sleeve 3 more stable when rotating.

[0045] like Figure 3-Figure 5As shown, a plurality of paddles 6 are evenly distributed on the surface of the transmission belt 4, and the spacing between each paddle 6 is the same. In this embodiment, each paddle 6 can be laid flat on the surface of the transmission belt 4 in a closed state, so that when the water flows through the flat paddle 6, it will not form additional resistance.

[0046] like Figure 1 and Figure 6 As shown, the paddle 6 is connected to the transmission belt 4 through a hinge device 9. Specifically, the hinge device 9 includes a hinge connection seat 91 fixedly arranged on the surface of the transmission belt 4 and a hinge connection rod 92 inserted into the hinge connection seat 91, and one end of the paddle 6 is movably connected to the hinge connection rod 92. Through the above arrangement, the paddle 6 can be turned over and formed into an unfolded state under the push of the water flow.

[0047] like Figure 3 and Figure 4 As shown, one end of the support block 7 is fixedly connected to the paddle 6, and the other end thereof extends downward and can abut against the surface of the transmission belt 4 after the paddle 6 is pushed by the water flow. Specifically, the end of the support block 7 after extending downward has an arc-shaped surface. Through the above arrangement, when the paddle 6 is in an unfolded state under the push of the water flow, the support block 7 can limit the unfolding angle of the paddle 6. At the same time, when the end of the support block is an arc-shaped surface, it can avoid damage to the surface of the transmission belt 4 when it abuts against the transmission belt 4.

[0048] like Figure 2 As shown, baffles 31 for preventing the transmission belt 4 from moving up and down are respectively arranged at the upper and lower ends of the sleeve 3. The diameter of the two baffles 31 is greater than the diameter of the sleeve 3.

[0049] Embodiment 2:

[0050] In order to keep the first blade 61 and the second blade 62 in the unfolded state after being impacted by the water flow, the first blade 61 can be kept in the unfolded state by replacing the support block 7 only by setting a connecting belt 10 on the right side of each first blade 61, and the second blade 61 can be kept in the unfolded state by replacing the support block 7 by setting a connecting belt 10 on the left side of each second blade 62. Specifically, one end of the connecting belt 10 on the first blade 61 is respectively fixed to the transmission belt 4, and the other end is fixedly connected to the first blade 61; correspondingly, one end of the connecting belt 10 on the second blade 62 is respectively fixed to the transmission belt 4, and the other end is fixedly connected to the first blade 62; through the above-mentioned arrangement, after the first blade 61 and the second blade 62 are impacted by the water flow, the connecting belt 10 can be tightened and fixed after the first blade 61 or the second blade 62 is unfolded to a certain angle, so that the first blade 61 or the second blade 62 can maintain the unfolded state under the impact of the water flow.

[0051] The following describes the use principle of the present invention to facilitate understanding of the present invention:

[0052] Specifically, when in use, the kinetic energy conversion device of the hydroelectric generator can be placed on the beach behind the river, wherein the blades 6 need to face the flow direction of the water flow when unfolded, so that the kinetic energy of the water flow can push the blades 6 and drive the transmission belt 4 to circulate and rotate on the two sleeves 3;

[0053] like Figure 3-Figure 4 As shown, when the water flows from right to left, the water pushes the first blade 61 to be in an expanded state; the first blade 61 is pushed by the water flow and moves in the direction of the sleeve 3 on the left side in sequence, so that the sleeve 3 and the gear 5 can be driven to rotate synchronously through the movement of the first blade 61, thereby realizing the conversion of the kinetic energy of the water flow into mechanical energy for power generation; because the gear 5 is connected to an external power generation device, the gear 5 can further convert the mechanical energy into electrical energy when it rotates. When the first blade 61 is in an expanded state, the second blade 62 will be in a closed state through the push of the water flow, so as to reduce the resistance generated by the water flow pushing the first blade 61.

[0054] like Figure 5 As shown, when the water flows from left to right, the water pushes the second paddle 62 to be in an expanded state; the second paddle 62 is pushed by the water flow and moves toward the right side of the sleeve 3 in sequence, so that the sleeve 3 and the gear 5 can be driven to rotate synchronously through the movement of the second paddle 62, thereby realizing the conversion of the kinetic energy of the water flow into mechanical energy for power generation; when the second paddle 62 is in an expanded state, the first paddle 61 is correspondingly in a closed state due to the push of the water flow.

[0055] In summary, by providing paddles 6 that open and close in coordination with the water flow on both sides of the transmission belt 4, the paddles 6 on both sides can continuously and stably convert the kinetic energy of the water flow into mechanical energy that can be used for power generation after being impacted by the water flow; when the paddles 6 on one side are unfolded, the paddles 6 on the other side can be closed in coordination to reduce the resistance generated when the water flow pushes the paddles 6 to unfold.

[0056] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
