Description

Technical Field

[0001] This invention relates to the field of rainwater treatment technology, specifically to a rainwater collection and utilization device for karst regions. Background Technology

[0002] In the existing technological field, various devices and methods have been developed and applied for rainwater harvesting and utilization. Rainwater harvesting technologies typically include basic rainwater harvesting systems such as rainwater bins, storage tanks, and more complex collection systems, which are widely used in residential, industrial, and agricultural sectors. The core objective is to capture and store rainwater for subsequent use, such as irrigation, domestic water use, or industrial water use. In some regions, especially those with scarce water resources or uneven rainfall distribution, rainwater harvesting systems have become an important means of supplementing water resources. However, existing rainwater harvesting technologies often focus on basic collection and storage functions, and may have limitations in terms of filtration efficiency, water quality management, and energy efficiency.

[0003] Existing technologies face challenges in handling unique geographical environments, such as the distinctive "two-dimensional and three-dimensional" topography of karst regions. Karst areas exhibit both geological fragility and sensitivity, low environmental carrying capacity, and are susceptible to severe anthropogenic disturbances that can exceed ecosystem health limits. Characteristics of karst regions include slow soil formation, shallow and discontinuous soil layers, low soil water retention capacity, and low vegetation cover. Rainwater harvesting systems may not be effective in managing the complex and variable rainfall patterns in karst areas. Ineffective rainwater harvesting exacerbates water scarcity, impacting daily life, agricultural irrigation, and rapid infiltration due to surface porosity. Traditional rainwater harvesting devices may lack the filtration precision and treatment efficiency required for specific regional water quality requirements, leading to inefficient water utilization. Effective rainwater harvesting and management are crucial for karst regions, not only as a key to addressing water scarcity but also as an important measure to protect and maintain local ecological balance and geological security. Therefore, it is necessary to develop more efficient, adaptive, and effective rainwater harvesting and utilization solutions specifically for karst topography. Summary of the Invention

A wastewater filtration mechanism effectively removes impurities and pollutants from the collected rainwater, ensuring water quality. This is crucial for ensuring local residents' water security and supporting agricultural production. Effective rainwater harvesting reduces the impact of rapid water infiltration on geological structures, thereby mitigating geological risks such as ground subsidence and ensuring environmental stability in karst areas. Through the power generation components in the switching and power mechanism, not only is rainwater harvested and utilized, but the kinetic energy of the water is also converted into electrical energy, increasing energy self-sufficiency and reducing dependence on external power sources. A backwashing mechanism effectively maintains the cleanliness of the filtration system, ensuring long-term efficient operation and reducing maintenance costs and labor input. Therefore, this device provides a comprehensive solution tailored to the specific conditions of karst topography, improving rainwater harvesting and utilization efficiency while ensuring water resource quality and sustainability, which is of great significance to the health and stability of local communities and ecosystems.

It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0028] Please see Figures 1-9 This application provides a karst area rainfall collection and utilization device, comprising: a housing 1, a sewage filtration mechanism 2, a collection and convergence mechanism 3, a branch collection mechanism 4, a switching and power mechanism 5, a backwashing mechanism 6, and a sewage discharge pipe 7. The sewage filtration mechanism 2 is located at the top of the housing 1; the collection and convergence mechanism 3 is located at the top of the sewage filtration mechanism 2; there are multiple branch collection mechanisms 4, each connected to the end of the collection and convergence mechanism 3; the switching and power mechanism 5 is fixedly installed at the top of the housing 1 and connected to the collection and convergence mechanism 3; the backwashing mechanism 6 is located at the top of the sewage filtration mechanism 2 and communicates with the bottom of the housing 1; the input end of the sewage discharge pipe 7 is connected to the end of the sewage filtration mechanism 2 through a valve body.

[0029] In the specific implementation process, it should be noted that when rainfall first occurs, the branch collection mechanism 4 initially collects rainwater, which then enters the switching and power mechanism 5 through the converging collection mechanism 3. Because a large amount of dirt (dust accumulated between the two rainfall stages) remains inside the branch collection mechanism 4 immediately after rainfall, the rainwater containing dirt enters the wastewater filtration mechanism 2 through the switching and power mechanism 5. After filtration, it is transported to one of the chambers within the housing mechanism 1 for storage. After the rainwater containing dirt has been transported for a period of time, the switching and power mechanism 5 switches, allowing the rainwater to enter another chamber of the housing mechanism 1 through the converging collection mechanism 3. The clean rainwater, free of dirt, is used to generate electricity through the power and switching mechanism, and after use, it directly enters the wastewater system. The rainwater is stored inside the housing 1, and the collection and gathering mechanism 3 serves as the rainwater collection point, further collecting and guiding rainwater from multiple sources to ensure efficient collection. The rainwater output position can be adjusted as needed through switching and power mechanism 5. During the collection and transmission of rainwater, the backwashing mechanism 6 cleans the wastewater filtration mechanism 2, ensuring that the filtration efficiency does not decrease due to long-term use. After a period of use, the backwashing mechanism 6 is activated, and the valve on the drain pipe 7 is opened, allowing wastewater to be discharged through the drain pipe 7. This device not only collects rainfall efficiently and effectively but also ensures the quality of the collected rainwater, adapting to the common precipitation patterns and geographical characteristics of karst landform areas.

[0030] Due to the porous nature of karst terrain, rainwater may contain significant amounts of soil and impurities. The wastewater filtration mechanism 2, located at the top of the housing mechanism 1, effectively filters these impurities, ensuring the quality of the collected water. In karst regions, the irregular terrain necessitates the use of a power and switching mechanism to supply power to the components of this device, effectively utilizing resources. The backwashing mechanism 6 is crucial for maintaining the long-term effective operation of the equipment. This device considers the unique geographical and hydrological conditions of karst topography and addresses the challenges to transportation and living environments posed by these conditions. By effectively collecting and utilizing rainfall, it provides vital water resource support for residents of karst regions.

[0031] In some examples, the housing mechanism 1 further includes a water tank 11, a water outlet 13, and a partition 14. The water outlet 13 is located at the bottom of the housing. The partition 14 is located inside the water tank 11 and divides the water tank 11 into two spaces, one of which is a sewage collection chamber 12 and the other is a clean water collection chamber 15. The sewage collection chamber 12 is connected to the sewage filtration mechanism 2.

[0032] In the specific implementation process, it should be noted that inside the water tank 11, a partition 14 divides it into two different spaces: a sewage collection chamber 12 and a clean water collection chamber 15. At the start of rainfall, rainwater first passes through the branch collection mechanism 4 and the convergence collection mechanism 3 of the equipment, filtering out larger impurities and dirt in the initial stage. The rainwater is then transported via a switching and power mechanism 5. The initially contaminated rainwater enters the sewage filtration mechanism 2, where residual pollutants are further separated. The sewage, with large impurities removed, enters the sewage collection chamber 12 within the water tank 11. The clean water collection chamber 15 is used to store clean rainwater, providing a safe and reliable water source for the karst region. As rainfall begins... As rainwater is continuously collected and filtered, the water level in the purified water collection chamber 15 gradually rises. When the collected water is needed, it can be obtained through the outlet 13 located at the bottom of the water tank 11. The backwashing mechanism 6 can further flush the sewage filtration mechanism 2 to prevent clogging. The sewage filtration mechanism 2 is cleaned regularly to ensure its continuous and efficient operation. Dirt and accumulated sewage are discharged through the sewage pipe 7. This device efficiently collects and utilizes rainfall. By separating water sources of different qualities, it ensures the quality of the collected rainwater. It is particularly adapted to the common precipitation patterns and geographical characteristics of karst landform areas, providing important water resource support for residents of karst areas, while also reducing dependence on groundwater resources.

[0033] In some examples, the wastewater filtration mechanism 2 further includes: a cover 21, a top cover 22, partitions 23, a filter screen 26, and a water quality sensor 27. The bottom of the inside of the cover 21 is sloped. The bottom of the top cover 22 is fixedly installed inside the cover 21. Two partitions 23 divide the cover 21 into three spaces. The bottom of the partitions 23 fits against the slope of the bottom of the cover 21, and there is a gap between the top of the partitions 23 and the top cover 22. The three spaces are two water passage chambers 25 and one filter chamber 24. The two water passage chambers 25 are located on both sides of the cover 21 and between the two partitions 23, and are connected to the wastewater collection chamber 12. The filter chamber 24 is located between the two partitions 23. The filter screen 26 is disposed at the top of the two partitions 23. The two water quality sensors 27 are disposed inside the two water passage chambers 25 respectively.

[0034] In the specific implementation process, it should be noted that the bottom of the inside of the cover 21 is sloping, which helps to guide the water flow and promote the filtration process. The top cover 22 is fixedly installed inside the cover 21, and its bottom end forms a closed space with the bottom of the cover 21. Inside the cover 21, two partitions 23 divide it into three spaces: two water passage chambers 25 and one filter chamber 24. A gap is maintained between the top of the partition 23 and the top cover 22, so that after the water flows through the middle filter chamber 24, it gradually spreads from the top to the two water passage chambers 25, so that the pre-treated water flows into the sewage collection chamber 12. The filtration mechanism is very suitable for the unique landform and hydrological conditions of karst areas, and can efficiently treat and utilize rainwater to provide reliable water resources for the region.

[0035] In some examples, the collection mechanism 3 further includes: a collection plate 31, an inclined surface 32, a water outlet cover 33, a filter plate 36, and a water outlet pipe 35. The bottom end of the collection plate 31 is fixedly installed on the top of the cover 21 by four support columns 34; multiple inclined surfaces 32 are respectively arranged at the bottom end of the collection plate 31; the end of the water outlet cover 33 is connected to the end of the collection plate 31; the filter plate 36 is arranged between the water outlet cover 33 and the collection plate 31; the input end of the water outlet pipe 35 is connected to the bottom end of the water outlet cover 33, and the output end is located inside the switching and power mechanism 5.

[0036] In the specific implementation process, it should be noted that the collecting plate 31 can effectively capture rainwater flowing in from the branch collection mechanism 4. The multiple inclined surfaces 32 at the bottom are designed to guide the rainwater to the lower part of the collecting plate 31 and promote the collection of rainwater. The collected rainwater enters the outlet hood 33. The filter plate 36 is set between the outlet hood 33 and the collecting plate 31 to filter the rainwater and remove larger particulate impurities from the rainwater, providing a certain guarantee for the subsequent filtration and storage process. The filtered rainwater can be effectively transferred to the switching and power mechanism 5, thus entering the next processing stage of the entire equipment. The collecting mechanism 3 efficiently captures and pre-treats rainwater, improves the efficiency of rainwater collection, and ensures the water quality flowing into the subsequent treatment stage. It is very suitable for application in the unique landform and hydrological conditions of karst areas, effectively utilizing rainfall resources.

[0037] In some examples, the branch collection mechanism 4 further includes: a water pipe 42, a collection tray 41, and a screen 43. There are several water pipes 42, and their output ends are respectively connected to the side of the collection tray 31. The corners of the several collection trays 41 are respectively connected to the several water pipes 42. The bottom surface of the collection trays 41 has a slope to facilitate the collection of rainwater to the input end of the water pipes 42. Several screens 43 are respectively set on the top of the several collection trays 41.

[0038] In the specific implementation process, it should be noted that there are multiple water pipes 42, with their output ends connected to the side of the collecting tray 31. This facilitates the introduction of collected rainwater from different locations into the collecting tray 31. All water pipes 42 are used to transport rainwater, ensuring that rainwater can flow smoothly from the collecting tray 41 to the collecting tray 31. The bottom surface of the collecting tray 41 has a certain slope, which helps rainwater to naturally converge towards the input end of the water pipes 42, allowing rainwater to flow more efficiently from the collecting tray 41 to the water pipes 42 and then into the collecting tray 31. The screen 43 performs preliminary filtration of the rainwater before it enters the water pipes 42, intercepting larger impurities and debris, such as leaves and branches, thus protecting the water. The water pipe 42 is not blocked, which also ensures the quality of rainwater flowing into the collection tray 31. In actual operation, when it rains, the rainwater first falls on the collection tray 41, and the screen 43 intercepts large particles of impurities. The rainwater flows along the slope of the collection tray 41 to the input end of the water pipe 42. After passing through the water pipe 42, the rainwater is effectively concentrated and introduced into the collection tray 31, and then enters the next processing stage of the equipment. The branch collection mechanism 4 achieves efficient rainwater capture and preliminary filtration through the effective combination of multiple water pipes 42, collection trays 41 and screens 43. It is very suitable for the unique terrain and climate conditions of karst areas, makes full use of rainfall, and provides important water resources for the region.

[0039] In some examples, the switching and power mechanism 5 further includes: a housing 51, a mounting plate 52, a switching assembly 53, and a power generation assembly 54. The bottom end of the housing 51 is fixedly disposed at the top end of the water tank 11; the edge portion of the mounting plate 52 is fixedly disposed inside the housing 51; the switching assembly 53 is disposed on the mounting plate 52 and the housing 51; and the power generation assembly 54 is located between the bottom end of the mounting plate 52 and the housing 51.

[0040] In specific implementation, it should be noted that the switching and power mechanism 5 realizes the switching control of rainwater flow direction and also uses rainwater flow to generate electricity, increasing the energy efficiency of the equipment. The housing 51 is the outer part of the switching and power mechanism 5, and its bottom end is fixedly set on the top of the water tank 11 to ensure the stability of the entire mechanism and enable it to withstand the pressure caused by water flow or other operations. The main function of the mounting plate 52 is to serve as a support platform for the switching component 53 and the power generation component 54, ensuring the correct position and stable installation of the components. The switching component 53 is responsible for controlling the rainwater flow direction. According to the needs of the system, it can switch the rainwater flow into the clean water collection chamber 15 or the sewage filtration mechanism 2, which can make the equipment more efficient. The device can flexibly adjust the water flow direction according to different working conditions, optimize the rainwater collection and treatment process, and the power generation component 54 uses the flowing rainwater to generate power, which is not only an effective use of resources, but also increases the self-sufficiency of the water pump in the equipment. It does not need to rely on external power supply. By converting the kinetic energy of rainwater into electrical energy, the power generation component 54 provides the required energy for other parts of the equipment, reducing the dependence on external power supply. The switching and power mechanism 5, through its switching and power generation functions, not only improves the efficiency of rainwater collection and utilization equipment in karst areas, but also realizes the effective utilization of rainwater energy. It is suitable for karst areas, which require efficient water resource management and energy utilization.

[0041] In some examples, the switching component 53 further includes: an electric actuator 532, a rotating plate 533, a drain pipe 534, and a sewage pipe 531. The electric actuator 532 is rotatably mounted on the mounting plate 52 via a hinge. The rotating plate 533 is rotatably mounted on the mounting plate 52, with one end movably connected to the telescopic end of the electric actuator 532, and the other end of the rotating plate 533 fixedly connected to the output end of the outlet pipe 35. The drain pipe 534 is mounted on the mounting plate 52, and the center of the drain pipe 534 is located on the rotation trajectory of the rotating plate 533. The sewage pipe 531 is mounted on the mounting plate 52 and is located directly below the outlet pipe 35.

[0042] In practical implementation, it should be noted that the switching component 53 ensures that rainwater can be effectively guided to the corresponding treatment stage according to different operating states of the equipment. The electric push rod 532 provides power to adjust the water flow direction. The extension and retraction of the electric push rod 532 can be precisely controlled to achieve the switching of the water flow path. When the electric push rod 532 extends or retracts, the rotating plate 533 rotates accordingly, thereby changing the direction of the output end of the water outlet pipe 35 fixedly connected to it. The rotating plate 533 switches the water flow into the drain pipe 534 or the sewage pipe 531 according to the action of the electric push rod 532. The center of the drain pipe 534 is located on the rotation trajectory of the rotating plate 533. When the rotating plate 533 rotates to a certain position, it can align the output end of the water outlet pipe 35 with the drain pipe 534. The water flows into the drain pipe 534 and then into the power generation component 54 to generate electricity. Finally, it flows into the clean water collection chamber 15 in the water tank 11. The sewage pipe 531 is located directly below the outlet pipe 35. When the rotating plate 533 rotates to the position of the sewage pipe 531, the output end of the outlet pipe 35 will be aligned with the sewage pipe 531, thereby guiding the water flow into the sewage pipe 531 until the sewage enters the sewage filtration mechanism 2. In actual operation, the electric push rod 532 adjusts the position of the rotating plate 533 through the telescopic action. Rainwater can be guided to the drain pipe 534 and the sewage pipe 531 as needed. This device can flexibly respond to different operating states, effectively manage and utilize the collected rainwater, and is very suitable for the special landforms and water resource management needs of karst areas.

[0043] In some examples, the power generation assembly 54 further includes: a cavity 541, a generator 543, blades 542, and a battery 544. The cavity 541 is fixedly disposed at the bottom end of the housing 51; the generator 543 is fixedly disposed at the bottom end of the housing 51, and the rotation shaft of the generator 543 extends into the interior of the cavity 541; a plurality of blades 542 are respectively fixedly disposed on the rotation shaft of the generator 543; and the battery 544 is disposed at the bottom end inside the housing 51.

[0044] In the specific implementation process, it should be noted that the power generation component 54 drives the generator 543 through the flow of rainwater, thereby generating electrical energy. When rainwater flows through the cavity 541, it drives the blades 542 mounted on the rotating shaft to rotate. Multiple blades 542 are fixedly mounted on the rotating shaft of the generator 543. When rainwater flows over the blades 542, the blades 542 are pushed by the water flow and rotate. The arrangement of the blades 542 ensures efficient energy conversion, enabling effective rotation even at low water flow speeds. The battery 544 is located at the bottom of the housing 51 and is used to store the electrical energy generated by the generator 543. 544 provides the necessary power to the electrical components in this device (such as water pump 62) and can also maintain some functions of the device when there is no rainwater flow. During the entire operation, rainwater drives the blades 542 to rotate as it passes through the cavity 541, thereby driving the generator 543 to generate electricity. The electricity is then stored in the battery 544 to provide energy for other parts of the device or external equipment. This not only makes effective use of rainwater resources but also increases the environmental friendliness and self-sufficiency of the device. It enables the rainwater harvesting and utilization equipment in karst areas to achieve energy recovery and utilization while collecting rainwater, adapting to the special geographical and environmental conditions of the region.

[0045] In some examples, the backwashing mechanism 6 further includes: a water pump 62, a water supply pipe 61, a water passage chamber 63, and a flushing assembly 64. The water pump 62 is located at the top of the cover 21; the input end of the water supply pipe 61 is connected to the water tank 11; the water passage chamber 63 is located in the middle of the top cover 22; and the flushing assembly 64 is rotatably mounted at the bottom of the top cover 22 and is connected to the water passage chamber 63.

[0046] In the specific implementation process, it should be noted that the backwashing mechanism 6 ensures that the wastewater filtration mechanism 2 in the equipment remains clean and operates efficiently. The water pump 62 is located at the top of the cover 21 and is responsible for driving the water flow. During the backwashing process, the water pump 62 draws water from the water tank 11 and delivers it to the filter screen 26 that needs to be cleaned through the water pipe 61. The power of the water pump 62 is sufficient to ensure the pressure and stability of the water flow throughout the cleaning process. The inlet end of the water pipe 61 is connected to the water tank 11, allowing the clean water to reach the flushing component 64 from the water tank 11. The water pipe 61 ensures that the water flow can reach the flushing component 64 smoothly and without obstruction, while avoiding any leakage or blockage. The water passage chamber 63 is located in the middle of the top cover 22 and distributes the water flow. When the clean water passes through the water pipe... After reaching the water passage chamber 63, the water 61 enters the flushing assembly 64. The flushing assembly 64 is rotatably installed at the bottom of the top cover 22 and is interconnected with the water passage chamber 63. When the flushing assembly 64 is in operation, it rotates and sprays high-pressure water to effectively remove dirt, sediment and other impurities accumulated in the filtration system. When backwashing is required, the water pump 62 is started to draw water from the water tank 11 and deliver the water to the water passage chamber 63 through the water pipe 61. After the water flow is evenly distributed through the water passage chamber 63, it is sprayed out by the flushing assembly 64 in a high-pressure form to thoroughly clean all parts of the sewage filtration mechanism 2. The backwashing process not only improves the filtration efficiency, but also extends the service life of the equipment, ensuring that the equipment can continue to operate effectively in the special environment of the karst region.

[0047] In some examples, the rinsing assembly 64 further includes: a rotating tube 642, an annular tube 641, a first nozzle 643, and a second nozzle 644. The middle portions of the rotating tubes 642 are rotatably disposed at the bottom end of the top cover 22. The annular tubes 641 are respectively connected to the outer side of the outer wall of the rotating tubes 642. The first nozzles 643 are respectively inclinedly disposed on the rotating tubes 642. The second nozzles 644 are respectively inclinedly disposed on the annular tubes 641.

[0048] In the specific implementation process, it should be noted that the flushing assembly 64 ensures that the sewage filtration mechanism 2 can be thoroughly cleaned and maintain its efficient operation. The rotating pipe 642 can rotate during the cleaning process, thereby improving the cleaning coverage. The rotating pipe 642 can make the nozzles spray water flow in different directions and angles, ensuring that each part can be cleaned evenly and thoroughly. The annular pipe 641 is connected to the outer side of the outer wall of the rotating pipe 642. The water flow processed by the annular pipe 641 is distributed to the first nozzle 643 and the second nozzle 644 on the rotating pipe 642. The first nozzle 643... The water jet is tilted and sprayed at an angle along the same direction of rotation. The spray angle and intensity of the first nozzle 643 generate a reaction thrust, thereby achieving the self-rotation effect of the entire flushing assembly. This ensures that every corner inside the hood 21 can be effectively cleaned, achieving all-round cleaning. It effectively removes dirt and deposits, ensuring the cleanliness and efficient operation of the filtration system. Therefore, the flushing assembly 64 not only improves cleaning efficiency but also ensures long-term stable operation of the equipment, making it suitable for addressing the cleaning and maintenance issues that may be encountered in the long-term use of rainwater harvesting and utilization equipment in karst areas.
