Detailed Implementation

[0024] like Figures 1-9 As shown, this invention discloses a distributed gravity energy storage green power generation system for long-distance ABR pipelines, comprising a pipeline body 1, a rotating shaft 2 extending radially along the pipeline body 1 and rotatably disposed within the pipeline body 1, and support and buffer assemblies 3 connected to both ends of the rotating shaft 2. The pipeline body 1 is inclined, allowing the potential energy of the medium to be converted into kinetic energy impacting the impeller device during flow. The rotating shaft 2 is arranged radially along the pipeline body 1, with both ends extending towards the inner wall of the pipeline body 1. The rotating shaft 2 is also kinetically connected to the input end of the power generation device 4. The support and buffer assemblies 3 are connected to the inner wall of the pipeline body 1.

[0025] A support frame 5 is coaxially connected to the rotating shaft 2. The support frame 5 is generally circular, and six sets of impeller assemblies 6 are evenly distributed around its outer circumference. Each set of impeller assemblies 6 includes radial rods 7 arranged parallel to both ends of the support frame 5, a first hinge shaft 8 and a second hinge shaft 9 connected parallel to the two radial rods 7. The two radial rods 7 are parallel to each other, and the axial direction of the radial rods 7 is perpendicular to the axial direction of the rotating shaft 2 and the support frame 5. The outer end of the radial rod 7 must be located inside the pipe body 1 to prevent interference with the inner wall of the pipe body 1 when it rotates.

[0026] The two ends of the first hinged shaft 8 and the second hinged shaft 9 are respectively rotationally matched with the radial rod 7, that is, the first hinged shaft 8 and the second hinged shaft 9 can rotate around their own axes, the distance between the first hinged shaft 8 and the rotating shaft 2 is greater than the distance between the second hinged shaft 9 and the rotating shaft 2. The first hinged shaft 8 is fixedly connected with the first impeller plate 10, the length direction of the first impeller plate 10 is parallel to the axial direction of the first hinged shaft 8, and the first hinged shaft 8 is fixed at the center of the first impeller plate 10. The second hinged shaft 9 is fixedly connected with the second impeller plate 11, the length direction of the second impeller plate 11 is parallel to the axial direction of the second hinged shaft 9, and the second hinged shaft 9 is fixed at the center of the second impeller plate 11. The side surfaces of the first impeller plate 10 and the second impeller plate 11 are simultaneously hinged through the first connecting rod 12 and the second connecting rod 13, the first impeller plate 10 and the second impeller plate 11 are parallel to each other, the first connecting rod 12 and the second connecting rod 13 and the side surfaces of the first hinged shaft 8 and the second hinged shaft 9 form a parallelogram, and the second impeller plate 11 is connected with the support frame 5 through the telescopic device 14. The overlapping area between the first impeller plate 10 and the second impeller plate 11 can be changed through the telescopic device 14, so that the working area of the whole impeller assembly 6 is changed, the flow of the impacted medium can be controlled, and the output power of the device can meet the needs of different users.

[0027] When the water flow in the long-distance ABR pipeline flows through the device under the action of gravitational potential energy, the impeller assembly 6 outside the support frame 5 is impacted, the impeller assembly 6 is forced to drive the rotating shaft 2 to rotate after the support frame 5, the rotating shaft 2 rotates to charge the power generation device 4, the power generation device 4 adopts existing charging equipment, including a rotor coaxially connected with the rotating shaft 2 and a stator corresponding to the rotor, and a relative motion between the rotor and the stator generates an induced electromotive force, thereby achieving the purpose of charging. Of course, the power generation device 4 can also be other devices that can convert the kinetic energy of the impeller assembly 6, which is not within the protection scope of the present application, and those skilled in the art should understand.

[0028] As a further improvement of the embodiment, a plurality of wave-breaking plates 15 are uniformly and spacedly arranged on the surface of the second impeller plate 11 along the length direction of the second impeller plate 11, the wave-breaking plates 15 are perpendicular to the surface of the second impeller plate 11, and the wave-breaking plates 15 can to a certain extent resist the impact of the water flow, slow down the instantaneous impact of the water flow on the impeller assembly 6, allow the water flow to act on the subsequent distributed power generation system more continuously and charge it, and also protect the device to a certain extent. A strip-shaped hole 16 is formed in the first impeller plate 10 for the wave-breaking plate 15 to pass through, and a round corner is formed at the position of the outer end of the wave-breaking plate 15 towards the first impeller plate 10 to avoid interference between the wave-breaking plate 15 and the device when rotating.

[0029] In the embodiment, the support frame 5 comprises a first circular ring 17, a second circular ring 18 arranged apart from the first circular ring 17, a connecting plate 19 connecting the first circular ring 17 and the second circular ring 18, the first circular ring 17 is located at the left side of the pipeline body 1, and the corresponding second circular ring 18 is arranged at the right side of the pipeline body 1, and the planes where the two are located are perpendicular to the rotating shaft 2. The connecting plate 19 is parallel to the rotating shaft 2, the first circular ring 17 is connected to the sleeve 21 through the first connecting rod 20, and the first connecting rod 20 is uniformly and spacedly arranged along the circumference of the first circular ring 17. The second circular ring 18 is connected to the first bevel gear 23 through the second connecting rod 22, but the sleeve 21 is coaxially and fixedly connected with the rotating shaft 2, and the first bevel gear 23 is coaxially and rotatably connected with the rotating shaft 2; the telescopic device 14 is connected with the support frame 5 through the connecting plate 19. By adopting the frame type support frame 5 structure, the blocking effect on the water flow can be reduced, the water flow can maintain good potential energy, and the energy loss can be reduced to cope with the power generation of the subsequent power generation device 4.

[0030] In the embodiment, the support buffer assembly 3 comprises a rectangular mounting seat 24 fixed on the inner wall of the pipeline body 1, the rectangular mounting seat 24 is arranged along the axial direction of the pipeline body 1, the rectangular mounting seat 24 is provided with a T-shaped sliding groove 25 along the axial direction of the pipeline body 1, the rotating shaft 2 is rotatably connected to a bearing seat 26, and the bearing seat 26 is slidably arranged in the T-shaped sliding groove 25. The T-shaped sliding groove 25 is used for limiting the outer surface of the bearing seat 26, that is, the bearing seat 26 can slide along the axis of the pipeline body 1 but cannot come out of the T-shaped sliding groove 25, and at the same time, the bearing seat 26 can be used for rotatably connecting with the rotating shaft 2, thereby achieving the function of rotation fit. The bearing seat 26 is connected with one end of the T-shaped sliding groove 25 through a spring damper 27. By arranging the spring damper 27, when the support frame 5 and the impeller assembly 6 connected therewith are subjected to a large instantaneous water flow impact, a certain degree of buffering can be achieved through the spring damper 27, thereby avoiding damage to the device caused by instantaneous impact. Through the short distance accommodation function of the spring damper 27, the water flow can be timely avoided, and the loss of water flow potential energy can also be reduced.

[0031] In the embodiment, the first bevel gear 23 is engaged with a second bevel gear 28, the axis of the second bevel gear 28 is perpendicular to the axis of the first bevel gear 23, the second bevel gear 28 is coaxially connected to the input end of the power generation device 4, and the first bevel gear 23 drives the second bevel gear 28 engaged therewith to rotate after the rotating shaft 2 rotates. At this time, the rotation of the second bevel gear 28 can drive the power generation device 4 to generate power, and the power generation device 4 is in sliding fit with the pipeline body 1. When the first bevel gear 23 and the rotating shaft 2 compress the spring damper 27 to displace under the action of instantaneous impact, the second bevel gear 28 engaged with the first bevel gear 23 can also drive the power generation device 4 to displace to a certain extent, so as to avoid damage to the power generation device 4. Of course, the displacement distance is small, and the first bevel gear 23 and the second bevel gear 28 will not be disengaged.

[0032] In this embodiment, the bottom of the power generation device 4 is fixed with a first limiting block 29 and a second limiting block 30, and a limiting groove 31 is formed between the first limiting block 29 and the second limiting block 30. The inner wall of the pipeline body 1 is fixed with a guide rail 32 along the axial direction, and the guide rail 32 is slidingly installed in the limiting groove 31. By setting the first limiting block 29 and the second limiting block 30, the power generation device 4 and the guide rail 32 can be set in a sliding fit manner, which can adapt to the impact of the water flow. The second bevel gear 28 is coaxially connected to a shaft sleeve 34 through a first center shaft 33, the shaft sleeve 34 is in rotational fit with the first center shaft 33 and is limited in the axial direction of the first center shaft 33, and a rotating connection hole 35 in rotational fit with the rotating shaft 2 is formed on the shaft sleeve 34 in the radial direction. The possibility of disengagement between the first bevel gear 23 and the second bevel gear 28 is reduced.

[0033] The impact of the water flow at the beginning may affect the rotating direction of the impeller assembly 6. Since the reverse rotation of the input shaft of the power generation device 4 will bring adverse effects to the device, in this embodiment, the reverse rotation can be avoided by setting the following device. Specifically, a ratchet wheel 36 is fixedly connected to the rotating shaft 2 in a coaxial manner, the ratchet wheel 36 is located on the back side of the first bevel gear 23, a pawl 37 is rotatably connected to the back side of the first bevel gear 23, a return torsion spring 38 is connected between the pawl 37 and the first bevel gear 23, and the inner end of the pawl 37 is always pivoted to the first bevel gear 23. Under the action of the return torsion spring 38, the outer end of the pawl 37 tightly abuts the outer circumference of the ratchet wheel 36. The rotating direction of the ratchet wheel 36 corresponds to the rotating direction of the rotating shaft 2. When the rotating shaft 2 rotates forward, it is used for generating electricity for the power generation device 4. At this time, the pawl 37 is engaged with the ratchet wheel 36 and the ratchet wheel 36 can drive the first bevel gear 23 to rotate, so as to facilitate the first bevel gear 23 to drive the second bevel gear 28 to rotate and realize power generation; when the ratchet wheel 36 reversely rotates, the pawl 37 slides off the outer surface of the ratchet wheel 36. At this time, the ratchet wheel 36 does not act on the pawl 37, and naturally does not drive the first bevel gear 23 to rotate, avoiding the adverse effects of reverse rotation on the power generation device 4, and improving the service life of the device.

[0034] In the embodiment, the pipe body 1 is connected with a column 39, the column 39 penetrates into the inside of the pipe body 1, the first bevel gear 23 is engaged with a third bevel gear 40, the axis of the third bevel gear 40 is perpendicular to the axis of the first bevel gear 23, the third bevel gear 40 is coaxially connected to a second center shaft 41, a through hole is arranged on the column 39 and is in sealing cooperation with the second center shaft 41, the second center shaft 41 can only slide on the column 39 but cannot rotate by arranging a convex rib on the inside of the column 39, when the second center shaft is pressed downward, the third bevel gear 40 is engaged with the first bevel gear 23, the third bevel gear 40 cannot rotate, thus the first bevel gear 23 can be stopped, the device can be manually prevented, and the device is convenient for subsequent maintenance. The second center shaft is connected to an end plate 42 after extending through the through hole, and the end plate 42 is connected with a tension spring 43 between the column 39. By arranging the tension spring 43, the third bevel gear 40 can be kept away from the first bevel gear 23, and the first bevel gear 23 is prevented from being affected when normally rotating.

[0035] In the embodiment, the rectangular mounting seat 24 is connected to the inner wall of the pipe body 1 through a support plate 44, the support plate 44 is fixedly connected with a mounting cylinder 45, the mounting cylinder 45 is arranged along the axial direction of the pipe body 1, the mounting cylinder 45 is in rotating cooperation with the rotating shaft 2, the bottom of the mounting cylinder 45 is connected with a floating ball 47 through a supporting spring 46, the diameter of the floating ball 47 is smaller than that of the mounting cylinder 45, the water flow is convenient for passing through, the floating ball 47 is connected with a limiting support 48, the limiting support 48 is provided with an open slot 49 with a width greater than the diameter of the rotating shaft 2, and the root of the open slot 49 is in frictional cooperation with the rotating shaft 2. The device is provided with the floating ball 47, the floating ball 47 drives the limiting support 48 to tightly adhere to the rotating shaft 2 under the action of the supporting spring 46, the rotating shaft 2 is prevented from rotating under the action of the frictional force, at this time, the power generation device 4 is not started, thus the small rate rotation is prevented from affecting the power generation device 4, and the service life of the device can be improved. Only when the flow of the medium reaches a certain threshold value, the water flow can impact the floating ball 47, the floating ball 47 moves to compress the supporting spring 46, the limiting support 48 is prevented from contacting the rotating shaft 2, at this time, the rotating shaft 2 can normally rotate to realize power generation. Of course, the rotating shaft 2 also compresses the supporting spring 46 through the limiting support 48 in the process of being greatly impacted and moved, but the frictional force is far less than the power of the rotating shaft 2 at this time, thus the rotating shaft 2 is slightly affected, and the normal power generation of the device is not affected.

[0036] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application.
