Description

Technical Field

[0001] The present invention belongs to the technical field of building drainage, and particularly relates to an energy-saving and environment-friendly building drainage system. Background Art

[0002] In the context of the continuous growth of global energy demand and the increasing awareness of environmental protection, the construction industry, as one of the main areas of energy consumption and carbon emissions, the innovation and application of energy-saving and emission-reduction technologies are particularly important. As a clean and renewable energy source, solar energy has been widely used in building rooftop photovoltaic power generation systems, effectively reducing the building's dependence on the traditional power grid, reducing carbon emissions, and setting an example for the green transformation of the construction industry.

[0003] However, although solar power generation technology has been relatively mature and widely used, the diversified utilization of building energy systems still faces many challenges. Especially in the rainy season, due to the reduction of sunshine hours, the efficiency of solar power generation will be significantly affected. At the same time, rainwater, as a widely distributed and easily accessible renewable water resource in nature, not only contains huge water volume potential, but also the kinetic energy and potential energy contained in its flowing process have the physical basis for conversion into electric energy, providing new possibilities for the diversification of building energy systems.

[0004] Traditional building drainage systems mainly focus on drainage design, and their functions are limited to quickly and safely discharging rainwater out of the building area, but they ignore the kinetic energy and potential energy contained in the flowing process of rainwater. These unutilized energies are quietly lost in rainwater runoff, resulting in a waste of energy resources. There are also some rainwater utilization devices in the prior art, which mainly focus on the collection and reuse of rainwater, such as for flushing toilets, irrigating farmland, etc. Although they improve the utilization efficiency of rainwater resources to a certain extent, they do not touch on the core issue of rainwater energy conversion. Therefore, in-depth research and practical application of rainwater power generation technology are still lacking.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment: Refer to Figures 1-7, the present invention provides an energy-saving and environmental-friendly building drainage system for houses, including a house body 1 and a water storage tank 2 on the back of the house body 1. A drain pipe 3 is penetrated through the house body 1, and a water storage tank 4 is provided at the water outlet end of the drain pipe 3. The water storage tank 4 is fixedly installed on the back side of the house body 1. A water storage and discharge assembly is provided in the water storage tank 4, and a water outlet pipe 5 is connected and communicated at the bottom of the end far from the drain pipe 3. A power generation assembly 6, a first pulley 7 and a second pulley 8 are provided at the bottom of the water storage tank 4. The power generation assembly 6, the first pulley 7 and the second pulley 8 are all installed on the house body 1. A one-way drive bearing sprocket 9 is fixedly installed on the input shaft of the power generation assembly 6. The first pulley 7 and the second pulley 8 are respectively located on both sides of the one-way drive bearing sprocket 9. The one-way drive bearing sprocket 9 is connected with a drive chain 10 in a transmission manner. Both ends of the drive chain 10 are wound around from the upper ends of the first pulley 7 and the second pulley 8 respectively, and a water bucket 11 and a counterweight 12 are respectively connected at both ends. The water bucket 11 is located between the water outlet pipe 5 and the water storage tank 2, and a guiding assembly for tipping the water bucket 11 is provided below the water bucket 11.

[0024] The specific working principle of this energy-saving and environmental-friendly building drainage system for houses is as follows: When rainfall occurs, rainwater converges on the roof of the housing body 1 and is introduced into the water storage tank 4 through the drain pipe 3 on the housing body 1. Inside the water storage tank 4, the water storage and discharge component automatically adjusts according to the water level change. Specifically, when the water level is lower than the designed water level, the water storage and discharge component remains closed, allowing the rainwater to continuously accumulate inside the water storage tank 4. When the water level exceeds the designed water level, the water storage and discharge component automatically opens, guiding the accumulated rainwater to the outlet side and discharging it into the lower water bucket 11 through the water discharge pipe 5. As the water bucket 11 continuously stores water, its weight gradually increases. When the total weight of the water bucket 11 exceeds the counterweight 12, under the action of gravity, the water bucket 11 begins to descend vertically. When the water bucket 11 descends to the position where the guiding component is located, under the action of the guiding component, the water bucket 11 completes the dumping action, pouring out the water inside it and being collected and stored in the storage pool 2, which is beneficial for the subsequent secondary utilization of rainwater, reduces the waste of water resources, and conforms to the concept of energy conservation and environmental protection. At the same time, after the water bucket 11 drains water, its weight suddenly decreases, and under the traction of the counterweight 12, the water bucket 11 begins to rise again, thus forming a reciprocating working mechanism. During this process, the driving chain 10 will reciprocate with the lifting and lowering of the water bucket 11, and then drive the one-way driving bearing sprocket 9 to rotate. It should be noted that due to the one-way driving characteristic of the one-way driving bearing sprocket 9, that is, when the one-way driving bearing sprocket 9 rotates in one direction, it will be in an idling state and will not drive the input shaft of the power generation component 6 to rotate. When the one-way driving bearing sprocket 9 rotates in the opposite direction, it can drive the input shaft of the power generation component 6 to rotate, so that the power generation component 6 effectively converts mechanical energy into electrical energy for supplying the power demand of the building. This one-way driving mechanism effectively avoids the energy loss and equipment wear problems that may be caused by the reciprocating rotation of the input shaft, and improves the system operation efficiency and durability. Compared with the traditional building drainage system, through the above design, this energy-saving and environmental protection building drainage system not only realizes the effective collection and discharge of rainwater, but also further utilizes the kinetic energy and potential energy contained in the flowing process of rainwater for power generation, realizing the energy utilization of rainwater. In the rainy season, it can effectively make up for the problem of the decline in solar power generation efficiency and power generation caused by the insufficient influence of sunlight on solar power generation efficiency, helps reduce the building's dependence on the traditional power grid, and improves the degree of diversified utilization of the building energy system. At the same time, it also enhances the building's energy supply capacity in the face of different climate conditions, effectively reduces the waste of energy resources and carbon emissions, and makes a positive contribution to promoting the green transformation of the building industry.

[0025] It is worth mentioning that the power generation component 6 adopts conventional technical means in the prior art, including generators, inverters, storage batteries, etc., which can be fully realized by those skilled in the art, so it will not be elaborated here.

[0026] In a specific embodiment, refer to Figure 6 and Figure 7, the water storage and discharge assembly includes a water baffle 13 and a buoyancy plate 14. Sliders 15 are provided on both sides of the water baffle 13, and chutes 16 matching with the sliders 15 are formed on both sides of the water storage tank 4. The buoyancy plate 14 is fixedly installed above the water baffle 13.

[0027] The water storage and discharge component realizes the water level regulation function through the cooperation of the water baffle 13 and the buoyancy board 14. Inside the water storage tank 4, at the beginning of rainfall, rainwater flows into the water storage tank 4 through the drain pipe 3. At this time, the water level in the water storage tank 4 has not reached the designed water level, and the rainwater continues to accumulate inside the water storage tank 4. As the rainwater continues to be injected, the water level in the water storage tank 4 gradually rises until it reaches the bottom of the buoyancy board 14. When it exceeds this position, the liquid level gradually submerges the buoyancy board 14, and the buoyancy board 14 also begins to be affected by the buoyancy force. When the buoyancy force exceeds the total weight of the buoyancy board 14 and the water baffle 13, the buoyancy board 14 will then be buoyed up above the water surface by the buoyancy force of the water. As the water level continues to rise, the buoyancy board 14 drives the water baffle 13 to move up together, causing a gap to form between the lower part of the water baffle 13 and the bottom of the water storage tank 4. At this time, the rainwater accumulated in the water storage tank 4 is discharged to the outlet side through this gap. As the rainwater continues to be discharged, the water level in the water storage tank 4 begins to drop, and the heights of the buoyancy board 14 and the water baffle 13 also drop accordingly. When the water level drops to a certain position where the buoyancy force is exactly equal to the total gravity of the buoyancy board 14 and the water baffle 13, at this time, the buoyancy board 14 is still floating on the water surface, the gap has not closed yet, and the rainwater is still being discharged, but the drainage speed has begun to slow down. As the water level continues to drop further, the buoyancy force continues to decrease and is not sufficient to support the buoyancy board 14 to continue floating. The buoyancy board 14 and the water baffle 13 continue to drop under the action of gravity, and the liquid level submerges the buoyancy board 14 again until the water level drops to the bottom position of the buoyancy board 14. The buoyancy board 14 and the water baffle 13 are reset, the gap is completely closed, and the water storage tank 4 enters the water storage stage again, waiting for the next cycle of water level rise and discharge. During this process, the opening degree of the lower gap of the water baffle 13 will be automatically adjusted according to the water level change. When the water level is relatively high, the opening degree of the gap is relatively large, and the drainage speed is relatively fast, which can quickly reduce the water level in the water storage tank 4 to cope with the possible overflow risk. When the water level drops, the opening degree of the gap gradually decreases, and the drainage speed slows down accordingly, ensuring that a certain amount of water is retained in the water storage tank 4 to maintain the system stability. This automatic adjustment mechanism enables the rainwater in the water storage tank 4 to form a periodic water storage and discharge cycle. By reasonably designing the drainage volume of the water storage tank 4 and the capacity of the water bucket 11, the water storage stage of the water storage tank 4 is skillfully staggered with the subsequent descending stage and the subsequent ascending stage after the water bucket 11 completes water storage. Specifically, when the water bucket 11 is in the descending stage after the water storage stage and the subsequent dumping and ascending stages, the water storage tank 4 is in the process of re-storing water, avoiding the impact on the water bucket 11 caused by the continuous large-flow drainage of the water outlet pipe 5. This coordinated cooperation of intermittent drainage and water storage effectively guarantees the running stability of the water bucket 11 during the operation process, thereby improving the running stability and reliability of the entire system during drainage and power generation, and realizing the efficient utilization of water resources and the stable supply of energy.

[0028] In a specific embodiment, refer to Figure 4 and Figure 5, the one-way drive bearing sprocket 9 includes an inner wheel 901 and an outer wheel 902 that are concentrically arranged. The inner wheel 901 is fixedly sleeved on the input shaft of the power generation assembly 6. The outer wheel 902 is arranged outside the inner wheel 901. The drive chain 10 is installed on the outer wheel 902. A plurality of ratchet teeth 903 that are inclined in the clockwise direction are uniformly arranged on the inner wall of the outer wheel 902. A latch 904 is hinged on the outer edge of the inner wheel 901. The other end of the latch 904 is in a blocking fit with the ratchet teeth 903. A spring plate 905 is arranged on the inner wheel 901. The spring plate 905 presses tightly against the latch 904 so that the latch 904 has a tendency to snap into the ratchet teeth 903.

[0029] The operating principle of the one-way drive bearing sprocket 9 is as follows: When the outer wheel 902 rotates clockwise driven by the drive chain 10, the latch 904 swings outward against the pressure of the spring plate 905 under the push of the inclined surface of the ratchet teeth 903. The outer wheel 902 can rotate freely without driving the inner wheel 901, that is, in an idling state, and will not drive the input shaft of the power generation assembly 6 to rotate. On the contrary, when the outer wheel 902 rotates counterclockwise driven by the drive chain 10, the spring plate 905 presses tightly on the latch 904, so that the other end of the latch 904 snaps into the ratchet teeth 903 to form a blocking fit. At this time, the outer wheel 902 can drive the inner wheel 901 to rotate, and then drive the input shaft of the power generation assembly 6 to rotate. This design ensures that the one-way drive bearing sprocket 9 has the characteristic of one-way drive, effectively avoiding the problems of energy loss and equipment wear that may be caused by the reciprocating rotation of the input shaft, and improving the operating efficiency and durability of the system.

[0030] In a specific embodiment, refer to Figure 1 and Figure 4 , the number of the power generation assemblies 6 is two. One-way drive bearing sprockets 9 are fixedly sleeved on the input shafts of the power generation assemblies 6. The drive chain 10 is wound around the two one-way drive bearing sprockets 9 in an S shape in sequence.

[0031] By using two power generation assemblies 6 and winding the drive chain 10 around the one-way drive bearing sprockets 9 on the input shafts of the two power generation assemblies 6 in an S shape in sequence, the meshing area between the drive chain 10 and the one-way drive bearing sprockets 9 is increased, making the contact between the drive chain 10 and the one-way drive bearing sprockets 9 more sufficient and the force more uniform, effectively improving the overall transmission efficiency. Moreover, due to the winding method of the drive chain 10, the rotation directions of the two one-way drive bearing sprockets 9 are opposite. Whether the drive chain 10 moves forward or backward, one of the two power generation assemblies 6 can be in a power generation state during the reciprocating movement of the drive chain 10. Compared with a single power generation assembly 6, more electric energy benefits can be generated, effectively improving the energy conversion rate.

[0032] In a specific embodiment, refer toFigure 1 , Figure 2 and Figure 3 , further comprising a first rod 17 and a second rod 18. The first pulley 7 and the second pulley 8 are respectively rotatably sleeved on the first rod 17 and the second rod 18. Support rods 19 are provided around the bottom of the water storage tank 4, and two ends of the first rod 17 and the second rod 18 are respectively connected to the adjacent support rods 19.

[0033] By arranging the support rods 19 around the bottom of the water storage tank 4, on the one hand, these support rods 19 provide a supporting effect for the water storage tank 4, and on the other hand, they also provide installation conditions for the first rod 17 and the second rod 18. By rotatably sleeving the first pulley 7 and the second pulley 8 on the first rod 17 and the second rod 18 respectively, smooth and stable rotation is achieved, providing a guiding effect for the driving chain 10 during movement, avoiding the situation of the driving chain 10 slipping, ensuring the continuity and stability of the transmission process of the driving chain 10, and effectively reducing the frictional resistance of the driving chain 10 during movement and reducing the energy loss during the transmission process.

[0034] In a specific embodiment, referring to Figure 2 and Figure 3 , first sliding seats 20 and second sliding seats 21 are symmetrically arranged at both ends of the water bucket 11 and both ends of the counterweight 12 respectively. The first sliding seat 20 is movably sleeved on the support rod 19 on one side of the water bucket 11 and is hinged to the water bucket 11. The second sliding seat 21 is movably sleeved on the support rod 19 on one side of the counterweight 12.

[0035] By symmetrically arranging the first sliding seats 20 and the second sliding seats 21 at both ends of the water bucket 11 and the counterweight 12 respectively and movably sleeving them on the support rods 19 on their respective sides. When encountering windy and rainy weather, the external wind force will inevitably act on the water bucket 11 and the counterweight 12 in the system. Since the first sliding seat 20 and the second sliding seat 21 respectively restrain the water bucket 11 and the counterweight 12 in a slidable manner on the support rod 19, while ensuring that the water bucket 11 and the counterweight 12 can move up and down, the influence of the wind force on the water bucket 11 and the counterweight 12 is effectively reduced, avoiding the excessive swing arc, and ensuring that the entire energy-saving and environmental protection building drainage system can still operate efficiently and reliably under complex weather conditions.

[0036] In a specific embodiment, referring to Figure 1 and Figure 2 , the guiding assembly includes a guiding groove 22 and a guiding rod 23. The guiding groove 22 is arranged below the water bucket 11, the water outlet end of the guiding groove 22 faces the storage pool 2, the guiding rod 23 is horizontally installed in the guiding groove 22, and a clamping groove 24 matching the guiding rod 23 is provided on one side of the bottom of the water bucket 11.

[0037] When the water bucket 11 descends to the position of the guide rod 23, the guide rod 23 is caught in the card slot 24 on one side of the bottom of the water bucket 11, forming a constraint relationship. Thereafter, as the water bucket 11 continues to descend, due to the limitation of the guide rod 23 and the traction of the driving chain 10, the water bucket 11 tilts towards the other side of the guide rod 23, so as to pour the water in the water bucket 11 into the guide groove 22. Under the guiding action of the guide groove 22, the rainwater is collected into the water storage tank 2, which is convenient for subsequent secondary utilization and effectively relieves the water use pressure.

[0038] In a specific embodiment, refer to Figure 1 , a cover plate 25 is provided above the water storage tank 2.

[0039] By providing the cover plate 25, the probability of accidental falling of personnel is effectively prevented, reliable safety protection is provided for the personnel activity area, and at the same time, the probability of impurities entering is reduced, the rainwater in the water storage tank 2 is prevented from being polluted, the quality of the collected rainwater is ensured to be relatively clean, and a good water quality basis is provided for subsequent secondary utilization.

[0040] In a specific embodiment, refer to Figure 1 , a drainage channel 26 which is inclined downward along the direction away from the water storage tank 2 is communicatedly provided on the top surface of the water storage tank 2.

[0041] By communicatively providing the drainage channel 26 on the top surface of the water storage tank 2, after the water storage tank 2 is full, the water can be discharged in time through the drainage channel 26 and away from the building, effectively avoiding potential safety hazards and adverse effects caused by water accumulation around the building.

[0042] In a specific embodiment, refer to Figure 1 , an overflow pipe 27 is communicatively provided at the top of the side surface of the water storage tank 4, and the water outlet end of the overflow pipe 27 extends into the drainage channel 26.

[0043] By communicatively providing the overflow pipe 27 at the top of the side surface of the water storage tank 4, when the rain suddenly increases or extreme rain conditions are encountered, the overflow pipe 27 can quickly discharge the rapidly increasing rainwater in the water storage tank 4 into the drainage channel 26, effectively avoiding exceeding the bearing capacity of the water storage tank 4 and ensuring the safe and stable operation of the water storage tank 4 under complex rain conditions.

[0044] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
