[0032] An embodiment of the present invention provides a power generation device, which is applied to a house 400. The specific structure and function of the power generation device provided by the embodiment of the present invention will be further described below with reference to text and drawings.

[0033] Reference Figures 1 to 4According to an embodiment of the present invention, a power generation device is provided for use in a house 400. The power generation device comprises a drainage pipe 100 and a power generation assembly 200. The drainage pipe 100 includes a drainage channel and multiple drainage connectors 110 connected to the drainage channel. The drainage connectors 110 are spaced apart from each other at various locations within the house 400, such as on the roof and between floors, to collect drainage from various areas of the house 400. The drainage channel is responsible for directing this drainage to the power generation assembly 200. The power generation assembly 200 comprises a first synchronous pulley 210, a second synchronous pulley 220, a synchronous belt 230, multiple water receiving boxes 240, and a generator 250. The first synchronous pulley 210 is located at the top of the house 400, and the second synchronous pulley 220 is located at the bottom of the house 400. The two are connected by a synchronous belt 230. The synchronous belt 230 is at least partially inserted into the drainage channel to interact with the water receiving box 240. Multiple water receiving boxes 240 are spaced apart on the synchronous belt 230. Their shape matches the shape of the drainage channel, ensuring that the water receiving boxes 240 can smoothly enter the drainage channel and receive water. At least one water receiving box 240 is always located in the drainage channel, ready to receive water flowing through the drainage connector 110. The generator 250 is located on one side of the first synchronous pulley 210 and generates electricity through the rotation of the first synchronous pulley 210.

[0034] When water is drained from the house 400 or when rain falls on the roof, the water flows through the drain connector 110 into the drainage channel and into the water receiving box 240. As the water is received, the water receiving box 240 moves downward along the synchronous belt 230 due to gravity. The movement of the water receiving box 240 drives the synchronous belt 230, which in turn drives the first and second synchronous pulleys 210 and 220 to rotate. The rotation of the first synchronous pulley 210 in turn drives the generator 250, thereby converting the kinetic potential energy of the water flow into electrical energy. When the water receiving box 240 reaches the bottom of the drainage channel, the second synchronous pulley 220 rotates, causing the water in the water receiving box 240 to drain through the opening. The weight of the water receiving box 240 decreases, and the box rises, ready to receive the next influx of water. This cycle repeats continuously, achieving the conversion of water flow kinetic energy into electrical energy.

[0035] The power generation device provided by the present embodiment utilizes the organic combination of the drain pipe 100 and the power generation assembly 200, utilizing the gravitational potential energy of the water flow to drive the movement of the water receiving tank 240. This, in turn, drives the synchronous pulley and generator 250 via the synchronous belt 230, thereby achieving energy conversion and utilization. This process requires no additional energy input, and the system features a simple structure and easy maintenance, reducing implementation difficulty and costs while improving economic efficiency. Furthermore, the design of the water receiving tank 240 enables it to adapt to varying water flow rates and water level fluctuations, enhancing environmental adaptability and facilitating large-scale deployment.

[0036] Reference Figure 2 and Figure 3 According to the power generation device provided by the embodiment of the present utility model, the power generation component 200 also includes a first fixing frame 260, which is arranged on the top of the house 400 and is used to firmly install the first synchronous wheel 210. The first fixing frame 260 is composed of a first base plate 261 and two first support plates 262. The first base plate 261 is tightly connected to the top of the house 400 through a suitable connection method to ensure the stability and firmness of the entire first fixing frame 260. The two first support plates 262 are arranged on the first base plate 261 at intervals, and a first mounting position is defined between the two first support plates 262. The design of the first mounting position takes into account the size and shape of the first synchronous wheel 210 to ensure that the first synchronous wheel 210 can be accurately installed therein and can maintain smooth operation during operation.

[0037] During the actual installation process, first, according to the top structure and size of the house 400, select a suitable position to install the first base plate 261, and firmly fix the first base plate 261 to the top of the house 400 by bolts or other connecting parts. Then, install the first synchronous wheel 210 in the first installation position and connect it to the first support plate 262 by bearings or other connection methods to ensure that the first synchronous wheel 210 can rotate freely.

[0038] Reference Figure 2 and Figure 3 According to the power generation device provided by the embodiment of the present invention, a first synchronous wheel 210 is provided with a drive shaft 211 and a drive wheel 212 connected to each other on the side facing the generator 250. The drive shaft 211 is a key component connecting the first synchronous wheel 210 and the drive wheel 212, ensuring that the rotation of the first synchronous wheel 210 can be accurately transmitted to the drive wheel 212. The drive wheel 212 is a gear with an appropriate number of teeth, which is used to mesh with the driven wheel of the generator 250. The rotating shaft of the generator 250 is connected to a driven wheel, which is also a gear with a number of teeth that matches the drive wheel 212 to ensure that the two can closely mesh and efficiently transmit rotation.

[0039] Reference Figure 1 It can be understood that a first protective shell is provided on the top of the house 400, and the first protective shell covers the first fixing frame 260, the driving shaft 211, the driving wheel 212 and the driven wheel, thereby preventing the first fixing frame 260, the driving shaft 211, the driving wheel 212 and the driven wheel from being exposed.

[0040] When the first synchronous wheel 210 rotates, driven by the water receiving tank 240 and the synchronous belt 230, the drive shaft 211 rotates accordingly, which in turn drives the drive wheel 212. The rotation of the drive wheel 212 is transmitted to the driven wheel through gear meshing, which in turn drives the shaft of the generator 250. In this way, the water flow power of the first synchronous wheel 210 is successfully converted into mechanical energy of the generator 250, which is then converted into electrical energy through the electromagnetic conversion device within the generator 250.

[0041] Reference Figure 3 According to the power generation device provided by the embodiment of the present utility model, the first support plate 262 is provided with a slide groove 263 arranged from top to bottom. The slide groove 263 provides a sliding track for the slider 264, allowing the slider 264 to freely rise or fall within the slide groove 263. The two ends of the first synchronous wheel 210 are rotatably connected to the sliders 264 on the two first support plates 262 via bearings. In this way, the first synchronous wheel 210 can rotate stably under the support of the sliders 264. A screw hole is provided at the top of the first support plate 262 to connect to the slide groove 263. An adjustment screw 265 is provided in the screw hole, and the lower end of the adjustment screw 265 can be locked in the slider 264. By rotating the adjustment screw 265, the slider 264 can be controlled to slide up and down within the slide groove 263, thereby driving the first synchronous wheel 210 to rise or fall accordingly.

[0042] In actual operation, when the height or position of the first synchronous wheel 210 needs to be adjusted, it is only necessary to rotate the adjustment screw 265. This adjustment method is not only simple and convenient, but also can accurately control the position of the first synchronous wheel 210, ensuring that it cooperates more closely and efficiently with components such as the synchronous belt 230 and the water receiving box 240.

[0043] Reference Figure 2 and Figure 4 According to the power generation device provided by the embodiment of the present invention, the power generation assembly 200 includes a second fixing frame 270. The second fixing frame 270 is composed of a second base plate 271 and a second support plate 272. The overall structure is strong and stable. The second base plate 271 is firmly mounted on the bottom of the house 400, providing a solid support foundation for the second fixing frame 270. Two second support plates 272 are arranged on the second base plate 271 at intervals, and a second mounting position is defined between the two second support plates 272. The size and shape of the second mounting position match the second synchronous wheel 220 to ensure that the second synchronous wheel 220 can be accurately installed therein and leave sufficient space for it to rotate freely.

[0044] When installing the second synchronous wheel 220, first secure the second base plate 271 to the bottom of the housing 400. Then, based on the size and position of the second mounting location, place the second synchronous wheel 220 between the two second support plates 272. Connect the second synchronous wheel 220 to the second support plates 272 using appropriate connection methods, such as bearings or rotating shafts, to ensure smooth rotation within the second mounting location.

[0045] Reference Figure 1 It can be understood that a second protective shell is provided at the bottom of the housing 400, and the second protective shell covers the second fixing frame 270 and the second synchronous wheel 220, thereby preventing the second fixing frame 270 and the second synchronous wheel 220 from being exposed.

[0046] Reference Figure 1 and Figure 2 According to the power generation device provided by the embodiment of the present invention, the power generation assembly 200 also includes a tensioning pulley 280 connected to the outer wall of the housing 400. The tensioning pulley 280 is securely attached to the outer wall of the housing 400 and is positioned between the first and second synchronous pulleys 210, 220, and on one side of the line connecting them. This not only enables the tensioning pulley 280 to effectively tension the synchronous belt 230, but also prevents interference with the motion trajectories of the first and second synchronous pulleys 210, 220.

[0047] The synchronous belt 230 is wound along a predetermined path around the first synchronous pulley 210, the second synchronous pulley 220, and the tensioning pulley 280. During installation, first ensure that the synchronous belt 230 is properly wound around the first and second synchronous pulleys 210, 220. Then, by adjusting the position and angle of the tensioning pulley 280, the synchronous belt 230 is appropriately tensioned on the tensioning pulley 280. This way, when the first synchronous pulley 210 is driven to rotate by the water flow, the synchronous belt 230, with the assistance of the tensioning pulley 280, can stably and tightly transmit power to the second synchronous pulley 220, thereby driving the generator 250 to generate electricity. The design of the tensioning pulley 280 not only improves the transmission efficiency and stability of the synchronous belt 230, but also, through its tensioning action, reduces loosening and slipping of the synchronous belt 230 during transmission, thereby extending the service life of the synchronous belt 230.

[0048] Reference Figure 2According to the power generation device provided by the embodiment of the present invention, the power generation component 200 also includes a fixing base 290, which is firmly fixed to the outer wall of the house 400 by fasteners, such as bolts, nuts, etc. This installation method is not only simple and convenient, but also can ensure that the connection between the fixing base 290 and the outer wall of the house 400 is tight and firm, providing a solid support foundation for the installation of the tensioning wheel 280. The tensioning wheel 280 is rotatably connected to the fixing base 290 by an appropriate connection method, such as a bearing or a rotating shaft. This allows the tensioning wheel 280 to rotate freely under the support of the fixing base 290, while maintaining close contact with the synchronous belt 230, ensuring that it effectively tensions the synchronous belt 230.

[0049] During the actual installation process, the mounting position of mounting base 290 is first determined based on the overall layout of the power generation device and the required location of tensioning pulley 280. Then, mounting base 290 is securely fastened to the outer wall of house 400 using fasteners. Next, tensioning pulley 280 is mounted on mounting base 290 and its position and angle are adjusted to ensure that the timing belt 230 exerts appropriate tension on tensioning pulley 280.

[0050] Reference Figure 1 It is understood that the outer wall of the housing 400 is provided with a third protective shell, which covers the tensioning wheel 280 and the fixing seat 290, thereby preventing the tensioning wheel 280 and the fixing seat 290 from being exposed. In addition, an inspection port is provided on one side of the third protective shell to facilitate subsequent maintenance.

[0051] Reference Figure 1 and Figure 2 According to the power generation device provided by the embodiment of the present invention, the power generation assembly 200 further includes two protective tubes 300, which are respectively disposed between the first synchronous pulley 210 and the tensioning pulley 280, and between the second synchronous pulley 220 and the tensioning pulley 280. The position and length of the protective tubes 300 can be adjusted according to actual needs to ensure that the majority of the synchronous belt 230 is located within the protective tubes 300 during transmission, thereby effectively protecting it.

[0052] During the actual installation process, the installation position and length of the protective tube 300 are first determined based on the transmission path of the synchronous belt 230 and the design requirements of the protective tube 300. Then, the protective tube 300 is fixed to the outer wall of the house 400 or other supporting structure to ensure that it matches the transmission path of the synchronous belt 230. Next, the synchronous belt 230 is passed through the protective tube 300, and its position and tension are adjusted to ensure that the synchronous belt 230 can be smoothly transmitted within the protective tube 300. By providing the protective tube 300, not only can the synchronous belt 230 be effectively protected and its damage from external environmental factors be reduced, but the overall aesthetics and safety of the power generation device are also improved. At the same time, the design of the protective tube 300 also facilitates daily inspection and maintenance of the synchronous belt 230, ensuring the long-term and stable operation of the power generation device.

[0053] According to the power generation device provided by the embodiment of the present invention, at least two fixing holes (not shown in the figure) are provided on the wall of the water receiving box 240 close to the synchronous belt 230, and fasteners are passed through the at least two fixing holes to fix the water receiving box 240 to the synchronous belt 230.

[0054] During the actual installation process, first determine the fixed position of the water receiving box 240 on the synchronous belt 230 based on the overall layout of the power generation device and the location requirements of the water receiving box 240. Then, use fasteners that match the fixing holes, such as bolts, nuts, etc., to pass through the fixing holes to firmly fix the water receiving box 240 on the synchronous belt 230. In order to ensure the firmness and stability of the fixation, at least two fixing holes are usually used for fixing, and the number of fixing holes can be increased as needed. Through such a design, not only is a stable connection between the water receiving box 240 and the synchronous belt 230 achieved, but the stability and reliability of the water receiving box 240 are also improved through the fixing method of the fasteners. At the same time, the design of the fixing holes also facilitates the subsequent daily inspection, maintenance and replacement of the water receiving tank 240, ensuring the long-term stable operation of the power generation device.

[0055] Furthermore, the use of fixing holes and fasteners makes installation and removal of the water receiving tank 240 much simpler and more convenient. To clean, repair, or replace the water receiving tank 240, simply loosen the fasteners to easily remove the water receiving tank 240 from the timing belt 230. To reinstall, simply insert the fasteners through the fixing holes and tighten them.

[0056] Reference Figure 1 According to the power generation device provided by the embodiment of the present invention, the drain pipe 100 is connected to the sewage pipe 310, and the sewage pipe 310 is located at the lower end of the drain pipe 100. Its horizontal arrangement makes the sewage discharge process smoother and more efficient.

[0057] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
