Description

Technical Field

[0001] The present invention belongs to the technical field of garden landscape, and more specifically, relates to a system and method for multi-stage rainwater blocking and soil recycling on garden roads. Background Art

[0002] Ecological gardens are to build multi-level, multi-structure, multi-functional and scientific plant communities to achieve harmonious coexistence between humans, nature and animals, and at the same time meet people's pursuit of ecological beauty, cultural beauty and artistic beauty. They enable the ecological environment and social and economic benefits to develop together, achieve a virtuous cycle, and create a clean, beautiful and civilized ecological environment for people.

[0003] Large areas of green plants in gardens need irrigation, and large areas of planting soil also need protection. However, most existing gardens are irrigated with tap water. A small number of gardens build ecological reservoirs and use rainwater collection and filtration systems to store rainwater in reservoirs for irrigation to achieve water conservation and protection. Patent document CN110005044A discloses a garden road with rainwater recovery, filtration and reuse functions, including a water storage channel, a reservoir, a road cover, an overflow pipe, a filter device and a rainwater reuse device. The water storage channel is located above the reservoir, the road cover is located above the water storage channel, the overflow pipe is connected to the water storage channel, the filter device is installed inside the water storage channel under the road cover, and the rainwater reuse device is installed inside the reservoir. The longitudinal cross-section of the water storage channel is U-shaped, with notches on the inner sides of the two ends of the top, and the notches have horizontal and vertical surfaces. There is a water outlet hole at the bottom of the water storage channel. The water storage tank is square in shape as a whole. There is a water inlet hole at the top of the water storage tank and a water outlet hole at the side of the water storage tank. The water inlet hole at the top of the water storage tank is connected to the water outlet hole at the bottom of the water storage channel. One end of the overflow pipe has an expansion joint. The rainwater recycling device has a submersible pump, a water pipe, a water distribution pipe and a water spray head. The submersible pump is installed on the lower side of the water storage tank. One end of the water pipe is connected to the submersible pump. The other end of the water pipe passes through the water outlet hole and is connected to one end of the water distribution pipe. The other end of the water distribution pipe is connected to the water spray head. The water spray head is spherical in shape as a whole and has water spray holes distributed on the water spray head. However, this solution cannot filter, separate and recycle the sludge at the front end.

[0004] However, the relevant complete set of technologies for combining garden water resource recycling and reuse with soil conservation, protection and collection and reuse is not mature enough. After rainwater enters the rainwater collection and filtration device, the rainwater is separated from the impurities and sediment therein, and the relevant sediment is directly discharged with the water flow. The conservation and protection of the soil is not in place, and the long-term soil loss will accumulate and bring irreversible effects to the ecological environment. Therefore, a multi-level anti-blocking device and construction method for rainwater on garden roads are provided to solve the problems raised in the above background technology. Summary of the invention

[0005] In view of the above defects or improvement needs of the prior art, the present invention provides a multi-level rainwater blocking and soil recycling and reuse system and method for garden roads, which adopts a detachable sludge recovery well with a socket-type blocking plate inside. A quick-detachable filter basket is designed on the top of the recovery well to prevent dead branches, leaves and other impurities from entering the rainwater collection system in large quantities. It solves the problem of setting a covering layer on the rainwater grate at any time, which causes rainwater to be undrained and causes water accumulation, affecting the survival of seedlings in the garden, and solves the problem that traditional rainwater wells cannot be disassembled and are not convenient for sludge recovery. The design of the blocking plate reduces the water flow velocity to a limited extent, prolongs the water path, and facilitates the sedimentation of silt soil particles by gravity.

[0008] The circular cone bucket safety diversion well includes a solid-liquid separator, a drainage collection pipe and a clean water separation pipe. The solid-liquid separator includes a front mud discharge pipe and a curved circular mud suction device. The front mud discharge pipe is connected to the solid-liquid separator. The solid-liquid separator introduces the separated clean water into the drainage collection pipe through the clean water separation pipe. The drainage collection pipe is connected to the sewage interception mechanism, and the sediment is caused to settle by slowing down the water flow speed and the mud and water are separated through the solid-liquid separator.

[0009] The sewage interception mechanism includes a sewage interception hanging basket and an automatic lifting device for the hanging basket. The sewage interception hanging basket filters impurities in rainwater through a filter screen. The sewage interception mechanism is connected to the waste flow device through a drainage main pipe, and impurities in rainwater are further filtered through the sewage interception hanging basket.

[0010] The flow abandonment device includes a buoyancy switch system, which switches the clean water pipe and the sewage pipe according to the amount of rainfall. The clean water pipe introduces clean rainwater into a water reservoir, which is connected to a ground sprinkler irrigation system. The sewage pipe is used to discharge rainwater directly into a municipal pipeline when the rainfall is heavy, thereby realizing multi-stage filtration, mud-water separation and resource recycling of rainwater.

[0011] Furthermore, the primary rainwater filtering mechanism also includes a detachable sludge recovery well, in which a socket-type blocking plate is provided, and a quick-detachable filter basket is installed on the top of the detachable sludge recovery well.

[0012] Furthermore, the quick-release filter basket is convenient for frequent replacement and cleaning through the quick-release design, thereby preventing the filter device from being blocked and ensuring that rainwater flows smoothly into the drainage collection pipe.

[0013] Furthermore, the solid-liquid separator guides the mud at the bottom of the diversion well to the solid-liquid separator through the front mud discharge pipe to separate the mud and water;

[0014] The arc-surface circular mud suction device is used for stirring the deposited silt to improve the efficiency of mud and sand separation.

[0015] Furthermore, the solid-liquid separator introduces the separated clean water into the drainage collection pipe through the clean water separation pipe, and discharges the silt sediment into the designated soil recovery equipment.

[0016] Furthermore, the sewage interception basket controls the automatic lifting device of the basket through an intelligent monitoring system.

[0017] Furthermore, the filter screen of the sewage interception hanging basket is used to intercept larger impurities in rainwater and further slow down the flow rate of rainwater, thereby promoting the sedimentation and separation of impurities.

[0018] Furthermore, the buoyancy switch system automatically adjusts the valve switch status of the clean water pipe and the sewage pipe according to different rainfall amounts;

[0019] When the rainfall is light, the clean water pipe is opened to direct clean rainwater into the reservoir;

[0020] When the rainfall is heavy, the sewage pipe is opened to discharge the excess rainwater directly into the municipal pipeline.

[0021] Furthermore, the water reservoir is connected to a ground sprinkler irrigation system, and the stored clean rainwater is used for garden irrigation.

[0022] According to a second aspect of the present invention, a method for multi-stage rainwater blocking and soil recycling for garden roads is provided, which is implemented by using the multi-stage rainwater blocking and soil recycling system for garden roads, and comprises:

[0023] S100: Rainwater passes through the quick-detachable filter basket in the primary rainwater filter mechanism, removes large impurities and enters the detachable sludge recovery well. It is slowed down and blocked by the socket-type blocking plate. The sludge settles at the bottom of the well and is cleaned regularly.

[0024] S200: Rainwater enters the circular cone bucket safety diversion well, and the sludge is sucked into the solid-liquid separator through the front mud discharge pipe and the arc-shaped circular mud suction device to achieve mud and water separation and obtain reusable planting soil;

[0025] S300: After secondary filtration, rainwater flows into the sewage interception mechanism, and impurities such as leaves and weeds are filtered out multiple times through the sewage interception basket. The intelligent monitoring system automatically triggers the automatic lifting device of the basket to clean up the impurities in the basket.

[0026] S400: Rainwater enters the waste flow device, and the buoyancy switch controls the clean water to flow into the reservoir through the clean water pipe during light rain. The clean water pipe is closed during heavy rain, and the sewage is directly discharged into the municipal pipeline through the sewage pipe.

[0028] 1. The system of the present invention adopts a detachable sludge recovery well with a socket-type blocking plate inside. A quick-detachable filter basket is designed on the top of the recovery well to prevent a large amount of impurities such as dead branches and leaves from entering the rainwater collection system. It solves the problem of setting a covering layer on the rainwater grate at any time, which causes water accumulation due to untimely rainwater drainage and affects the survival of seedlings in the garden. It also solves the problem that traditional rainwater wells cannot be disassembled and are not convenient for sludge recovery. The design of the blocking plate effectively reduces the water flow speed, prolongs the water path, and facilitates the sedimentation of silt soil particles by gravity.

[0029] 2. The system of the present invention adopts an innovative design, and the bottom of the safety separation well is set as a circular cone bucket, which can make silt and other impurities gather at the bottom of the cone bucket under the action of weight, so that the front mud discharge pipe can transport the silt to the solid-liquid separator. It solves the problem that the traditional flat-bottom safety separation well cannot concentrate the silt and cannot be automatically collected by fixed equipment, realizes the recycling and reuse of silt, and protects water and soil resources.

[0030] 3. In the system of the present invention, the mud suction device at the front section of the mud discharge pipe is designed to be an arc-shaped circle, which is convenient for the mud suction device to fit with the bottom of the circular cone bucket, and can effectively ensure the airtightness of the mud suction system, solving the problem of low suction force when the mud suction pipe is directly placed at the bottom of the cone bucket.

[0047] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. 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. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0048] like Figure 1 As shown, in the embodiment of the present invention, a multi-stage anti-blocking device for rainwater on a garden road and a soil recycling and reuse system are provided, including a primary rainwater filtration mechanism 1, a circular cone bucket type safety diversion well 2, a sewage interception mechanism 3, a flow abandonment device 4 and a water storage tank 5 which are sequentially connected by pipelines. Among them, rainwater passes through the rainwater wellhead on the garden road, flows through the primary rainwater filtration mechanism 1, and then enters the circular cone bucket type safety diversion well 2. The sludge at the bottom is sucked in for mud separation. After separation, the planting soil can be improved and reused. The discharged water enters the sewage interception mechanism 3. When too much impurities accumulate in the hanging basket, causing the rainwater flow rate to slow down, the intelligent monitoring system lifts the hanging basket and dumps the impurities inside it, and then the hanging basket automatically returns to the initial position. The water that has been filtered three times by the sewage interception mechanism enters the waste flow device 4. When the rainwater is small, the buoyancy is small, the suspended ball falls, the sewage drainage pipe outlet is closed, and the clean water flows into the reservoir; when the rainwater flow is large, the suspended ball floats up, the buoyancy switch closes the clean water pipe, and the sewage flows directly into the municipal pipeline. Finally, the usable water after filtration and sedimentation enters the reservoir 5, which solves the problem that the conventional use of vegetation soil on the rainwater manhole cover has good filtering and adsorption effects, but cannot be drained in time when the rainfall is heavy, resulting in water accumulation. The system of the present invention adopts a detachable sludge recovery well with a socket-type blocking plate arranged inside. A quick-detachable filter basket is designed on the top of the recovery well to prevent a large amount of impurities such as dead branches and leaves from entering the rainwater collection system. It solves the problem of the traditional covering layer set on the rainwater grate at any time, which causes water accumulation due to untimely rainwater drainage and affects the survival of seedlings in the garden. It also solves the problem that the traditional rainwater well cannot be disassembled and is not convenient for recovering sludge. The design of the blocking plate reduces the water flow speed to a limited extent, prolongs the water path, and facilitates the sedimentation of silt soil particles by gravity.

[0049] Specifically, a multi-stage anti-blocking device for rainwater on a garden road and a soil recycling and reuse system include a primary rainwater filtration mechanism 1, a circular cone bucket safety diversion well 2, a sewage interception mechanism 3, a flow abandonment device 4, and a water storage tank 5, which are sequentially connected by pipelines. The primary rainwater filtration mechanism 1 has a detachable sludge recovery well 11 inside the system, and a spigot-type blocking plate 111 is arranged inside the system, and a quick-detachable filter basket 112 is installed on the top surface of the detachable sludge recovery well 11. The primary rainwater filtration mechanism 1 is connected to the circular cone bucket safety diversion well 2 through a drainage collection pipe 13, and a front mud discharge pipe 211 and a curved circular mud suction device 212 are arranged inside the circular cone bucket safety diversion well 2. The front mud discharge pipe 211 is connected to an external mud solid-liquid separator 21, and the sludge and the like are separated by the solid-liquid separator 21, and the separated clean water flows into the drainage collection pipe 22 through the clean water separation pipe 23. The circular cone bucket safety diversion well 2 is connected to the sewage interception mechanism 3 through the drainage pipe 22, and the sewage interception hanging basket 31 is connected to the hanging basket automatic lifting device 32. The sewage interception mechanism 3 is connected to the abandoned flow device 4 through the drainage main pipe 33. The abandoned flow system 4 is equipped with a buoyancy switch system 41. The buoyancy switch system 41 switches the valve switch state of the clean water pipe 42 and the sewage pipe 43 according to the different rainfall. The abandoned flow system 4 is connected to the reservoir 5, and the reservoir 5 is connected to the ground spray irrigation system. The present invention has the functions of improving the cleanliness of rainwater, collecting organic sludge, and protecting soil and water loss, which meets the requirements of the state for protecting water and soil resources and protecting the environment.

[0050] like Figure 2 and Figure 3As shown, the primary rainwater filtration mechanism 1 is an important component of the multi-stage anti-blocking device for rainwater on garden roads and the soil recycling and reuse system. Its design includes a detachable sludge recovery well 11, a socket-type blocking plate 111, a quick-detachable filter basket 112 and a drainage collection pipe 13, which has a compact structure and coordinated functions. First, the rainwater passes through the quick-detachable filter basket 112 to preliminarily remove large particles of impurities such as leaves, dead branches and sand. The filtered rainwater enters the detachable sludge recovery well 11, and a socket-type blocking plate 111 is provided in the well. The blocking plate effectively slows down the water flow speed, blocks larger particles of silt, and causes the sludge to settle to the bottom of the recovery well to prevent it from entering the downstream pipeline. The detachable design makes it easy to clean and recycle the sludge. The treated sludge can be used as a modified material for garden planting soil and further used for soil reuse. Subsequently, the rainwater after primary filtration enters the circular cone bucket safety diversion well 2 of the next level through the drainage collection pipe 13. This design can not only effectively block impurities and achieve preliminary purification of rainwater, but also reduce maintenance costs through modular and detachable components to ensure the stable operation of the system. In addition, the system realizes the recycling of resources and avoids soil erosion through the recovery and reuse of sediment, which meets the national requirements for soil and water resource protection and environmental protection. The multi-stage filtration and purification function of the overall structure greatly improves the cleanliness of rainwater, reduces the burden on subsequent treatment devices, and ensures the efficient and sustainable operation of the entire rainwater collection and reuse system.

[0051] like Figure 4-Figure 6As shown, the circular cone bucket safety diversion well 2 is the core intermediate processing unit in the multi-stage anti-blocking device for rainwater in garden roads and the soil recycling and reuse system, which is responsible for effectively treating impurities, silt and organic matter in rainwater through multi-stage filtration and separation technology. The diversion well is composed of a solid-liquid separator 21, a front mud discharge pipe 211, a curved circular mud suction device 212, a drainage collection pipe 22 and a clean water separation pipe 23. First, after the rainwater enters the diversion well, the heavier silt and impurities settle to the bottom of the well due to the slowdown of the water flow. Through the front mud discharge pipe 211, the deposited sludge is guided to the solid-liquid separator 21 for mud and water separation. The design of the solid-liquid separator ensures that the sludge and organic matter in the rainwater can be treated in time to prevent impurities from entering the downstream drainage system. The curved circular mud suction device 212 can stir and absorb the sludge at the bottom of the well through its unique design, ensuring that the sediment will not stay at the bottom of the diversion well for a long time, avoiding the occurrence of blockage problems. The clean water after solid-liquid separation treatment is discharged into the reservoir or subsequent system through the clean water separation pipe 23, while the remaining silt is discharged into the next-level treatment unit, such as the sewage interception mechanism, through the drainage collection pipe 22. This design not only ensures the efficient separation of silt and water and improves the cleanliness of rainwater, but also facilitates the maintenance and operation of the system through modular design, and reduces the risk of blockage caused by silt accumulation. At the same time, the separated clean water can be further used for water storage or irrigation systems to achieve the recycling of water resources, which meets the requirements of environmental protection and water and soil resource protection. The present invention adopts an innovative design to set the bottom of the safety separation well into a circular cone bucket, which can realize that silt and other impurities are gathered at the bottom of the cone bucket under the action of weight, so that the front mud discharge pipe can transport the silt to the solid-liquid separator. It solves the problem that the traditional flat-bottomed safety separation well cannot concentrate the silt and cannot be automatically collected by fixed equipment, realizes the recycling and reuse of silt, and protects water and soil resources. In addition, the mud suction device at the front section of the mud discharge pipe of the present invention is designed to be an arc-shaped circle, which is convenient for the mud suction device to fit with the bottom of the circular cone bucket, and can effectively ensure the airtightness of the mud suction system, solving the problem of low suction force when the mud suction pipe is directly placed at the bottom of the cone bucket. In addition, by designing a mud stirring device, sludge can be collected efficiently.

[0052] like Figure 7As shown, the sewage interception mechanism 3 is an important filtering unit in the multi-stage anti-blocking device for rainwater in garden roads, which is responsible for further removing larger impurities in the rainwater and ensuring the smooth flow of the drainage system. Its main components include a sewage interception hanging basket 31, an automatic lifting device for the hanging basket 32, and a drainage collection pipe 33. When rainwater enters the sewage interception mechanism, larger impurities such as leaves, dead branches, and weeds in the rainwater will be intercepted by the sewage interception hanging basket 31 to prevent these impurities from entering the subsequent drainage system. A filter screen is provided in the sewage interception hanging basket 31, which can effectively filter these larger particles of impurities. As impurities gradually accumulate in the hanging basket, the automatic lifting device 32 of the hanging basket will detect the accumulation of impurities through the intelligent monitoring system. When the impurities accumulate to a certain extent, the lifting device automatically starts, lifts the hanging basket to a predetermined position, and cleans the impurities therein to ensure the normal operation of the system, and then the hanging basket automatically resets. The present invention adopts a sewage interception hanging basket connected with an automatic lifting device. The sewage interception hanging basket is provided with a filter net. The intelligent monitoring system is used to monitor the water flow velocity flowing through the sewage interception hanging basket, thereby solving the problems of filtering and separating and automatically dumping light impurities such as dead branches and leaves, and realizing intelligent operation of dumping the sewage interception hanging basket, liberating labor and improving construction efficiency of personnel.

[0053] like Figure 8 As shown, the flow abandonment device 4 is a key unit in the multi-stage anti-blocking device for rainwater on garden roads and the soil recycling and reuse system, which is responsible for intelligently diverting rainwater according to the amount of rainfall to optimize the utilization and management of water resources. Its main components include a buoyancy switch system 41, a clean water pipe 42 and a sewage pipe 43. The buoyancy switch system 41 detects the size of the rainwater flow by the rise and fall of the buoyancy ball, thereby automatically controlling the opening and closing of the clean water pipe 42 and the sewage pipe 43. When the rainfall is small, the buoyancy ball is in a low position, the clean water pipe 42 is opened, and the clean rainwater after multi-stage filtration is guided to the reservoir for subsequent garden irrigation and other purposes, reducing the waste of water resources; when the rainfall is large, the buoyancy ball rises, the buoyancy switch system 41 closes the clean water pipe 42, and opens the sewage pipe 43 at the same time, and discharges the excess rainwater directly into the municipal drainage system to avoid overloading or overflowing the reservoir. The abandoned flow device ensures that rainwater can be efficiently managed under different rainfall conditions by intelligently controlling the water flow path. On the one hand, it realizes the recycling and reuse of rainwater, and on the other hand, it reduces the burden on the sewage system, protects the environment and optimizes the allocation of water resources. The present invention uses the buoyancy principle, and a buoyancy switch is provided in the abandoned flow device. The lower part of the suspension ball is connected to the clean water pipe switch. The change in the size of rainwater is used to realize the diversion of clean water and muddy water, ensure the cleanliness of the water tank, and eliminate the problem of frequent flushing of the water tank. It solves the traditional manual control, saves human resources, and realizes automatic control.

[0054] like Fig. 9As shown, in another embodiment of the present invention, a multi-stage anti-blocking device for rainwater on a garden road and a soil recycling and reuse method are provided. On rainy days, rainwater passes through the rainwater well on the garden road, flows through the primary rainwater filtering mechanism 1, and then enters the drainage collection pipe 13, which solves the problem that the vegetation soil on the conventional rainwater well cover has good filtering and adsorption effects, but cannot be drained in time when the rainfall is heavy, resulting in water accumulation. The rainwater is first filtered through the quick-detachable filter basket 112 to remove impurities such as dead branches and leaves in the water, and the filtered rainwater enters the detachable sludge recovery well 11. The blocking and deceleration effect of the socket-type blocking plate 111 prevents rainwater from directly entering the drainage collection pipe 13, and by extending the drainage route and reducing the water flow rate, the sludge in the water is precipitated to the bottom of the sludge recovery well. When the sludge deposition reaches a certain amount, the detachable sludge recovery well 11 can be taken out to recover the sludge inside it. The rainwater after primary filtration enters the circular cone bucket safety diversion well 2. The water inlet of the diversion well is higher than the water outlet. By gravity, impurities, nutrients and silt mixed in the rainwater are deposited at the bottom of the cone bucket. The front mud discharge pipe 211 is arranged at the bottom of the cone bucket, and a curved circular mud suction device 212 is installed at its end. The device is equipped with a curved circular stirring mud suction head 213, which can stir the sludge and suck it into the front mud discharge pipe 211. Through the solid-liquid separator 21, the sludge at the bottom of the cone bucket is sucked in for mud separation. The planting soil after separation can be improved and reused, and the discharged water is discharged into the sewage interception well again through the clean water separation pipe 23. Lighter impurities in the rainwater, such as leaves, are filtered twice in the diversion well, and the rainwater flows into the sewage interception mechanism 3. A sewage interception hanging basket 31 is arranged in the sewage interception mechanism, and a round hole is arranged on the water-facing surface of the hanging basket to facilitate the entry of impurities into the hanging basket. The sewage interception hanging basket 31 is equipped with a filter net to intercept impurities such as leaves, branches and weeds. When too much impurities accumulate in the hanging basket, causing the rainwater flow rate to slow down, the intelligent monitoring system will automatically turn on the hanging basket automatic lifting device 32, lift the hanging basket and dump the impurities inside it, and then the hanging basket will automatically return to the initial position. The water filtered three times by the sewage interception mechanism enters the flow abandonment device 4. The flow abandonment device is equipped with a buoyancy switch 41, the lower part of which is connected to the clean water pipe 42. When the rainwater is small, the buoyancy is small, the suspension ball falls, the sewage drainage pipe mouth is closed, and the clean water flows into the reservoir; when the rainwater flow is large, the suspension ball floats up, the buoyancy switch closes the clean water pipe, and the sewage flows directly into the municipal pipeline. Through the above-mentioned multi-level filtration system design, the cleanliness of rainwater flowing into the reservoir can be improved, the pollutants entering the reservoir and remaining can be reduced, and the cleanliness of the reservoir can be guaranteed. At the same time, the rainwater collection system not only realizes the recycling of rainwater, but also takes into account the recycling and reuse of garden planting soil, effectively preventing soil erosion, and meeting the requirements of national soil and water resource protection and environmental protection.The method of the present invention adopts a detachable sludge recovery well and a quick-detachable filter basket to effectively remove large particles of impurities in rainwater, and at the same time realizes efficient separation and recovery of sludge through the solid-liquid separator and the front mud discharge pipe in the circular cone bucket diversion well. The sewage interception mechanism automatically cleans and filters impurities through intelligent monitoring, and the waste flow device intelligently switches the clean water pipe and the sewage pipe according to the rainfall, ensuring that a small amount of rainwater is used for recycling in the reservoir to avoid water accumulation caused by heavy rain. The system not only improves the efficiency of rainwater treatment, but also reduces environmental pollution by recycling soil and rainwater, which meets the requirements of water and soil resource protection and environmental protection.

[0055] It will be easily understood by those skilled in the art that 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.
