It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] Please also read Figures 1 to 12 Now, a water conservancy power generation device for a drainage riser of a high-rise building provided by the present invention is described. The water conservancy power generation device for a drainage riser of a high-rise building comprises a water pipe 1, a first shell 2, a water wheel 3 and a generator 4; the water pipe 1 is used to be connected to the drainage pipe of the high-rise building; the outer peripheral wall of the water pipe 1 has an avoidance hole 11; the first shell 2 is connected to the water pipe 1 at the position of the avoidance hole 11; the first shell 2 is connected to the water pipe 1; the water wheel 3 is rotatably arranged in the first shell 2; a part of the blades of the water wheel 3 is located in the water pipe 1, and the rotating shaft 31 of the water wheel 3 passes through the first shell 2; the generator 4 is connected to the outer side wall of the first shell 2; the output shaft of the generator 4 is connected to the rotating shaft 31 of the water wheel 3, and the generator 4 is connected to a battery (not shown in the figure) through a cable.

[0041] The present invention provides a hydraulic power generation device for a drainage riser of a high-rise building. Compared with the prior art, water in the drainage pipe of the high-rise building falls into the water pipe 1, and the water flow provides power to the blades of the water wheel 3, so that the blades of the water wheel 3 can rotate around the rotating shaft 31; during the rotation of the blades of the water wheel 3, the rotating shaft 31 of the water wheel 3 can drive the output shaft of the generator 4 to rotate, thereby realizing the process of power generation; since the generator 4 is connected to the battery through a cable, the electric energy generated by the generator 4 can be stored in the battery; compared with the prior art, which requires sewage to be pre-treated by sewage treatment equipment and then generate electricity, the present application does not need to pre-treat sewage, and the present application directly uses the gravitational potential energy of sewage to generate electricity, which is convenient for modifying the drainage pipes of existing high-rise buildings.

[0042] For example, the middle of the water wheel 3 has a spline groove, and the rotating shaft 31 of the water wheel 3 is a spline shaft, which is plugged into the spline groove; a spline sleeve 41 is fixedly provided on the output shaft of the generator 4, and the end of the spline shaft is plugged into the spline sleeve 41. A sealing cylinder 32 is fixedly provided on the side of the water wheel 3 close to the spline sleeve 41, and the sealing cylinder 32 is plugged into the through hole of the first shell 2, and the sealing cylinder 32 is sealed with the first shell 2; the sealing cylinder 32 has a spline hole for plugging with the spline shaft; through the above-mentioned configuration of the present application, the sealing performance of the side of the water wheel 3 close to the spline sleeve 41 and the first shell 2 can be ensured.

[0043] Exemplarily, the other side of the first housing 2 also has a through hole for the spline shaft to pass through. When the spline shaft is plugged into place, one end of the spline shaft is plugged into the spline sleeve 41, and the spline shaft is plugged into the spline groove of the water wheel 3. The other end of the spline shaft is located in the side wall of the first housing 2; the first housing 2 is provided with a sealing disc 21 and a sealing sleeve 22 at the position of the other end of the spline shaft, and the sealing disc 21 and the sealing sleeve 22 are fixedly connected; the sealing sleeve 22 is inserted into the through hole of the first housing 2, and the sealing sleeve 22 is plugged into the spline shaft. The part where the spline shaft and the sealing sleeve 22 are plugged in is not provided with a spline. The sealing disc 21 is located on the outside of the first housing 2 and is fixed to the first housing 2 by bolts. Through the above arrangement, the sealing performance of the spline shaft and the other side of the first housing 2 can be guaranteed. After removing the sealing disc 21, the spline shaft can be pulled out from the first housing 2, and then the water wheel 3 can be taken out from the first housing 2, which is convenient for cleaning or replacing the water wheel 3.

[0044] In some embodiments, Figures 1 to 12 As shown, an inspection port 23 is provided on the first shell 2, and a sealing cover plate 24 is detachably provided at the position of the inspection port 23; the inspection port 23 is arranged opposite to the avoidance hole 11, the top of the sealing cover plate 24 is hinged to the top of the first shell 2, and the bottom of the sealing cover plate 24 is connected to the bottom of the first shell 2 by bolts.

[0045] It should be noted that the side of the sealing cover 24 that contacts the inspection port 23 is provided with a sealing gasket. When the sealing cover 24 closes the inspection port 23, the sealing cover 24 can be fixed to the first shell 2 by bolts. At this time, the sealing gasket presses against the inspection port 23 and the sealing cover 24 to reduce sewage leakage from the connection between the sealing cover 24 and the inspection port 23.

[0046] Exemplarily, the first shell 2 has three threaded holes near the bottom of the inspection port 23. The three threaded holes are taken as an example, but are not limited to three threaded holes. The sealing cover plate 24 has through holes corresponding to the threaded holes one by one. When the sealing cover plate 24 closes the inspection port 23, the through holes on the sealing cover plate 24 correspond to the threaded holes one by one. At this time, the sealing cover plate 24 is fixed to the first shell 2 by bolts.

[0047] In some embodiments, Figures 1 to 12 As shown, a second shell 5 is connected to one side of the first shell 2, and a generator 4 is arranged in the second shell 5; wherein a fixing structure is connected to the generator 4, and the fixing structure is detachably connected to the second shell 5; and a through hole is provided on the side of the second shell 5 for the cable to pass through.

[0048] It should be noted that by setting a second shell 5 on one side of the first shell 2, a mounting platform can be provided for the generator 4; by setting a fixing structure on the generator 4 and detachably connecting the fixing structure to the second shell 5, the generator 4 can be fixed on the second shell 5, or the generator 4 can be removed from the second shell 5.

[0049] Exemplarily, both sides of the second shell 5 that are perpendicular to each other are openings, which facilitates placing the generator 4 in the second shell 5; an L-shaped sealing plate 51 is provided on the second shell 5, and the sealing plate 51 can close the openings on both sides of the second shell 5 that are perpendicular to each other; a threaded hole is provided at the open end of the second shell 5, and a through hole aligned with the threaded hole is provided on the sealing plate 51; after the generator 4 is fixed on the second shell 5, the sealing plate 51 is used to close the opening of the second shell 5, and the sealing plate 51 is fixed to the second shell 5 by bolts; through the above-mentioned arrangement, the generator 4 can be protected.

[0050] Exemplarily, heat dissipation holes 52 can be set on the second shell 5 and the sealing plate 51, and the heat dissipation holes 52 can be strip-shaped structures; heat dissipation fins (not shown in the figure) can be set on the outer wall of the second shell 5 and the outer wall of the sealing plate 51. By setting the heat dissipation holes 52 and heat dissipation fins, the heat dissipation performance can be improved.

[0051] In some embodiments, Figures 1 to 12As shown, the fixing structure includes a fixing frame 42, a plurality of fixing nuts 43 and a plurality of fixing bolts 44; the fixing frame 42 is fixed on the generator 4; the plurality of fixing nuts 43 are arranged on the top of the fixing frame 42; the top of the fixing frame 42 has a socket 421 for plugging and matching with the fixing nut 43; the fixing bolt 44 is threadedly matched with the fixing nut 43; wherein, the bottom of the second shell 5 has a through hole for the fixing bolt 44 to pass through, the threaded end of the fixing bolt 44 passes through the second shell 5, and the nut of the fixing bolt 44 is located outside the second shell 5.

[0052] It should be noted that the socket 421 on the top of the fixing frame 42 is a hexagonal hole, and the bottom wall of the socket 421 has a through hole for the threaded end of the fixing bolt 44 to pass through, and the diameter of the through hole is smaller than the outer diameter of the nut. Therefore, when the fixing bolt 44 and the fixing nut 43 are threadedly matched, the fixing nut 43 and the fixing bolt 44 can fix the fixing frame 42 on the second shell 5.

[0053] In some embodiments, Figures 1 to 12 As shown, a liquid level gauge 6 is provided on the top of the first shell 2, and the detection head of the liquid level gauge 6 is located in the first shell 2, and the detection head is sealed with the first shell 2; the power generation device also includes a control module and an alarm module, and the control module is electrically connected to the liquid level gauge 6 and the alarm module respectively; wherein, when the liquid level gauge 6 detects the liquid level, the liquid level gauge 6 generates a liquid level signal and transmits it to the control module; the control module controls the alarm module to alarm; the liquid level gauge 6 is a prior art and will not be described in detail here.

[0054] Exemplarily, the control module and the alarm module are arranged in the control room, and the control room has a power supply. When the water level reaches the detection head position of the liquid level meter 6, the liquid level meter 6 generates a liquid level signal and transmits it to the control module, and the control module transmits an alarm signal to the alarm module. At this time, the alarm module alarms, which can remind the staff of the blockage, so that the staff can deal with the blockage in time.

[0055] For example, an alarm module may also be provided on the first housing 2 to facilitate the staff to quickly identify the problematic pipe. The power generation device of the present application may be applied to various drainage pipes of high-rise buildings, including kitchen drainage pipes, bathroom drainage pipes, and balcony drainage pipes; the power generation device of the present application may be installed at the bottom floor of the high-rise building, not limited to the bottom floor, but also at other locations; the power generation device of the present application is not installed at the top floor of the drainage pipe.

[0056] It should be noted that when the power generation device of the present application is applied to various drainage pipes, the power generation device of the present application is installed on the kitchen drainage pipe, the bathroom drainage pipe and the balcony drainage pipe respectively. Therefore, the power generation device of the present application does not change the sewage discharge routes of the various drainage pipes.

[0057] In some embodiments, Figures 1 to 12 As shown, the sealing cover plate 24 is made of a transparent material, and the inner side of the sealing cover plate 24 has an arc-shaped chamber 241 for avoiding the blades of the water wheel 3.

[0058] It should be noted that since the sealing cover plate 24 is made of transparent material, it is convenient for the staff to observe the situation inside the first shell 2; by providing an arc-shaped chamber 241 on the inner side of the sealing cover plate 24, it can play a role in avoiding the blades of the water wheel 3, and during the rotation of the water wheel 3, it can prevent the water wheel 3 from colliding with the sealing cover plate 24.

[0059] In some embodiments, Figures 1 to 12 As shown, a receiving bag (not shown in the figure) is provided on the outer peripheral wall of the first shell 2 at the position of the inspection port 23, and the bag mouth of the receiving bag can be mounted on the first shell 2 to receive sewage and debris flowing out of the first shell 2; when the receiving bag is mounted on the first shell 2, the receiving bag is fixed to the first shell 2 by a clamp; wherein, a discharge port is provided at the bottom of the receiving bag, and the discharge port of the receiving bag is placed in a receiving tube (not shown in the figure).

[0060] It should be noted that the caliber of the receiving bag on the first shell 2 is much larger than the diameter of the first shell 2. Therefore, after the receiving bag is mounted on the first shell 2 and the bolts on the sealing cover 24 are removed, the sealing cover 24 can be flipped upward. At this time, the sealing cover 24 is still in the receiving bag, that is, the sealing cover 24 can be opened in the receiving bag; therefore, the sewage in the water pipe 1 can flow into the receiving bag and flow into the receiving tube along the receiving bag, thereby reducing the sewage flowing to the ground and reducing the difficulty of cleaning the ground.

[0061] For example, when a blockage occurs, after discharging the sewage accumulated in the water pipe 1, the receiving bag is removed from the first shell 2, and then the sealing disk 21 and the sealing sleeve 22 are removed from the first shell 2, and the spline shaft is pulled out. At this time, the water wheel 3 can be taken out of the first shell 2, which is convenient for cleaning the water wheel 3.

[0062] Exemplarily, the bottom surface inside the first shell 2 is a slope 25, which is inclined toward the shell pipe from the inspection port 23; during the normal sewage discharge process, if there is sewage in the first shell 2, the sewage will flow to the bottom surface of the first shell 2 and flow back to the water pipe 1 along the bottom surface to achieve the sewage discharge function and reduce the sewage accumulated in the first shell 2.

[0063] In some embodiments, Figures 1 to 12As shown, the receiving bag has a disassembly hole for the nut of the bolt to pass through, and the receiving bag is fixedly provided with a connecting ring 7 at the position of the disassembly hole. The inner peripheral wall of the connecting ring 7 is connected with a plurality of fan-shaped pieces 71, and the plurality of fan-shaped pieces 71 can close the disassembly hole; wherein each fan-shaped piece 71 is elastic, and the nut of the bolt can pass through the plurality of fan-shaped pieces 71. The number of connecting rings 7 on the receiving bag corresponds to the number of bolts; the large end of the fan-shaped piece 71 is fixed on the inner peripheral wall of the connecting ring 7, and the side walls of adjacent fan-shaped pieces 71 are in contact with each other.

[0064] It should be noted that when the water pipe 1 is blocked, the receiving bag is sleeved on the first shell 2 and fixed by a clamp; the connecting ring 7 on the receiving bag is sleeved on the nut of the bolt, and the nut is passed through the connecting ring 7. At this time, the bolt is removed by a disassembly tool and taken out of the connecting ring 7; after the bolt is separated from the connecting ring 7, the fan-shaped piece 71 in the connecting ring 7 recloses the disassembly hole; through the above arrangement, when the receiving bag is sleeved on the first shell 2, the bolt on the sealing cover can also be disassembled, and the sewage flowing out of the connecting hole can be reduced. Exemplarily, the fan-shaped piece 71 can be made of rubber.

[0065] For example, the rotating shaft 31 of the water wheel 3 in the present application is located in the first housing 2, and the rotating shaft 31 of the water wheel 3 is located outside the water pipe 1, that is, the rotating shaft 31 of the water wheel 3 in the present application is not arranged in the water pipe 1; through the above arrangement, it is possible to avoid the situation where sewage directly hits the rotating shaft 31 of the water wheel 3. Because if sewage directly hits the rotating shaft 31 of the water wheel 3, the sewage cannot provide torque to the water wheel 3, affecting the rotation of the water wheel 3.

[0066] In addition, since the rotating shaft 31 of the water wheel 3 is located outside the water pipe 1, it is possible to reduce the occurrence of hair and debris in the sewage being entangled on the rotating shaft 31 of the water wheel 3. The specific description is as follows:

[0067] If the rotating shaft 31 of the water wheel 3 is arranged inside the water pipe 1, since there is a gap between the end of the water wheel 3 and the inner circumferential wall of the water pipe 1, the part of the rotating shaft 31 close to the inner circumferential wall of the water pipe 1 is exposed inside the water pipe 1; when hair and debris in the sewage fall to the exposed position of the rotating shaft 31, the rotating shaft 31 can support the hair and debris on the one hand, and on the other hand, during the rotation of the rotating shaft 31, the hair and debris will be entangled on the rotating shaft 31, thereby increasing the resistance to the rotation of the rotating shaft 31 and affecting the rotation of the rotating shaft 31.

[0068] The above-mentioned method in the present application can reduce the situation where hair and debris fall on the exposed position of the shaft 31, thereby reducing the situation where hair and debris are entangled in the exposed position of the shaft 31.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
