Description

Technical Field

[0001] The invention belongs to the technical field of overflow wells, and in particular relates to a composite function overflow well with a modular design. Background Art

[0002] The sponge city rain garden includes vegetation, covering layer, planting layer, fine sand layer and gravel layer. The gravel layer can store water. When the water in the gravel layer reaches the designed amount, the water level will continue to rise. When the water level is higher than the overflow well, the water will overflow into the overflow well and enter the rainwater collection network through the drainage pipe. The current overflow well still has the following shortcomings:

[0003] 1. Some leaves or grass roots are easy to clog the overflow port and need to be cleaned frequently. Patent application number 201921981766.7 discloses that a filter grate is arranged at the wellhead of the overflow well to intercept blockages such as leaves, but when there are many leaves, the grate will also be clogged. Based on this patent, how to extend the wellhead clogging time and how to quickly and timely clean the leaves and other blockages on the grate are problems that need to be solved.

[0004] 2. When there is a lot of rain, the rainwater entering the overflow well from the wellhead has no time to be discharged, the water flow in the underground drainage pipe is overloaded, and the water will overflow from the overflow well to the surface. In addition, the area below the overflow well is a humid environment all year round, and odor will overflow. The patent with application number 202010120027.X solves the problem of water overflowing the surface by designing a water baffle, but it cannot solve the problem of odor overflowing from the bottom of the well. The patent with application number 201920605948.8 designs a baffle controlled by a spring. The baffle can isolate the bottom of the well from the outside world under the action of the spring to prevent the odor from overflowing from the bottom of the well. However, this spring-driven baffle will lose its function of blocking the odor from overflowing from the bottom of the well due to spring failure after long-term use.

[0005] 3. Cats or other small animals may mistakenly enter the drain pipe at the bottom of the overflow well and find it difficult to get out. If the cat or small animal that enters dies in the pipe because it cannot get out, the drain pipe will be blocked and cannot drain effectively. How to make the small animals that enter the drain pipe come out by themselves without affecting the normal use of the drain pipe is a problem that needs to be solved.

[0006] 4. The planting layer is the soil layer that provides the plants with the nutrients they need for growth. The roots of the plants are all located in the planting layer. The wellhead of the current overflow well is a certain distance higher than the covering layer covering the planting layer. If the rainfall is heavy, water will accumulate in the planting layer, causing the plants whose roots are located in the planting layer to be at risk of drowning.

[0007] 5. Rainwater sensors installed in overflow wells can sense overflow signals and judge that the rainwater is too heavy, but they cannot make stage-by-stage judgments. For example, after the planting layer is flooded, the first alarm is needed because the plants in the planting layer are at risk of drowning. It also means that the rainwater is greater than the water storage capacity of the gravel layer, or that the rainwater is so heavy that the water in the planting layer cannot catch up and infiltrate the gravel layer. This needs to be judged, but the current rainwater sensors can only sense when overflowing, and at this time, the planting layer has already been flooded, even for a long time. At this time, it is a bit late to take pipe network diversion measures.

[0008] The present invention designs a modular composite function overflow well to solve the above problems. Summary of the invention

[0009] Based on this, it is necessary to provide a modularly designed composite function overflow well in view of the problems existing in the current overflow well. The present invention can achieve long-term low-water-level overflow by staggering the six first grates and the six second grates in the slag blocking assembly, ensuring that the outer side of the well mouth of the overflow well is in a low-water-level state for a long time to facilitate overflow and drainage. When a lot of slag is accumulated on the first grates in the low-water-level overflow state, the shell drives all the first grates to swing up through the lever on the seat plate to clean the slag. While cleaning the slag on the first grates, the six second grates are still in a state of overflowing the surrounding accumulated water without affecting the overflow, thereby ensuring the overflow efficiency. The overflow well assembly in the present invention can effectively prevent the increasing amount of water in the well from flowing back toward the wellhead through the odor-isolating and anti-reversal assembly when the drainage flow rate of the drainage pipe at the lower end of the wellbore is less than the water inlet flow rate of the connecting pipe, ensuring that the water flowing through the drainage pipe of the nearby connected overflow well can be discharged smoothly through the underground pipe network. After the drainage peak of the underground pipe network has passed, the odor-isolating and anti-reversal assembly automatically opens and maintains the smooth downward discharge of the overflow water at the wellhead. The odor-isolating and anti-reversal assembly of the overflow well assembly in the present invention can automatically close and effectively isolate the bottom of the well from the outside world when it is not overflowing and draining water, preventing the stench generated by the bottom of the well being in a humid state for a long time from escaping upward through the wellhead, ensuring that the air around the wellhead of the overflow well is always clear, so that people sitting on the seat board to rest have a better rest experience, and there is no risk of failure of the odor-isolating and anti-reversal assembly, which has the characteristics of long-term continuous functioning and low maintenance cost. The water replenishment component in the present invention can regularly replenish water to the odor-isolating and anti-reversal component that can form a water seal. The water replenishment component can automatically close after the odor-isolating and anti-reversal component is filled with enough water, thereby reducing water resource waste and achieving the purpose of saving water resources. The street lamp component connected to the drain pipe at the lower end of the shaft of the overflow well component in the present invention allows the lower animals entering the drain pipe to escape from the predicament upward through the top rod through the vertically spaced rings in the hollow lamp pole and the water-absorbing annular sponge arranged between adjacent rings. At the same time, the annular sponge in the lamp pole can effectively absorb water and prevent the water in the drain pipe from being discharged upward through the lamp pole without blocking the passage of small animals, thereby ensuring that all the water in the drain pipe is effectively discharged through the underground pipe network. The overflow well assembly of the present invention is provided with a drain port on the wellbore wall, the drain port is located in the planting layer, and a fine sand annular belt and a coarse sand annular belt are provided around the drain port to filter the accumulated water entering the wellbore from the planting layer, thereby preventing the plant roots in the planting layer from rotting or drowning due to excessive water accumulation. At the same time, the accumulated water in the planting layer is prevented from carrying a lot of debris into the wellbore through the drain port, thereby causing blockage of the wellbore after long-term use, thereby effectively reducing the maintenance cost of the overflow well assembly.

[0024] The beneficial effects of the present invention are:

[0025] 1. The present invention can achieve long-term low-water-level overflow by staggering the six first grates and the six second grates in the slag blocking assembly, ensuring that the outer side of the overflow well mouth is in a low-water-level state for a long time to facilitate overflow and drainage. When a lot of slag is accumulated on the first grates in a low-water-level overflow state, the shell drives all the first grates to swing up through the lever on the seat plate to clean the slag. While cleaning the slag on the first grates, the six second grates are still in a state of overflowing the surrounding accumulated water without affecting the overflow, thereby ensuring the overflow efficiency.

[0026] 2. The overflow well assembly in the present invention can effectively prevent the increasing amount of water in the well from flowing back toward the wellhead through the odor-isolating and anti-reverse assembly when the drainage flow of the drainage pipe at the lower end of the wellbore is less than the water inlet flow of the connecting pipe, thereby ensuring that the water flowing through the drainage pipe of the nearby connected overflow well can be discharged smoothly through the underground pipe network. After the drainage peak of the underground pipe network has passed, the odor-isolating and anti-reverse assembly automatically opens to maintain the smooth discharge of overflow water at the wellhead.

[0027] 3. The odor-isolating and anti-reversal component of the overflow well assembly in the present invention can be automatically closed and effectively isolate the bottom of the well from the outside world when the overflow drainage is not in progress, thereby preventing the stench generated by the long-term humid state of the bottom of the well from escaping upward through the wellhead, ensuring that the air around the wellhead of the overflow well is always clear, so that people sitting on the seat board to rest have a better rest experience. In addition, the odor-isolating and anti-reversal component has no risk of failure, has the characteristic of continuously exerting its function for a long time, and has low maintenance costs.

[0028] 4. The water replenishing component in the present invention can regularly replenish water to the odor-isolating and anti-reversal component that can form a water seal. The water replenishing component can automatically close after the odor-isolating and anti-reversal component is filled with sufficient water, thereby reducing water waste and achieving the purpose of saving water resources.

[0029] 5. The street lamp assembly connected to the drain pipe at the lower end of the shaft of the overflow well assembly in the present invention enables animals entering the drain pipe to escape from the predicament upward through the top rod through the vertically spaced circular rings in the hollow lamp pole and the water-absorbing annular sponge provided between adjacent circular rings. At the same time, the annular sponge in the lamp pole can effectively absorb water and prevent the water in the drain pipe from being discharged upward through the lamp pole without hindering the passage of small animals, thereby ensuring that all the water in the drain pipe is effectively discharged through the underground pipe network.

[0030] 6. A drain port is provided on the wellbore wall of the overflow well assembly in the present invention. The drain port is located in the planting layer and a fine sand annular belt and a coarse sand annular belt are provided around the drain port to filter the accumulated water from the planting layer entering the wellbore, thereby preventing the plant roots in the planting layer from rotting or drowning due to excessive water accumulation. At the same time, the accumulated water in the planting layer is prevented from carrying more debris into the wellbore through the drain port, thereby causing blockage of the wellbore after long-term use, thereby effectively reducing the maintenance cost of the overflow well assembly.

[0031] 7. The second and first rain sensors installed can respectively alarm the amount of rainwater, which is convenient for collecting information on rainwater of different sizes. With the help of cloud platform data processing, digital and phased green space rainfall monitoring, alarm and early warning functions can be realized. After the planting layer is flooded, the second rain sensor in the fine sand layer senses the signal, warning that the rainwater has accumulated too much, or the rainwater precipitation speed is too fast to catch up with the infiltration into the gravel layer. At this time, the pipe network should be adjusted in time to guide the water to the centralized water storage area of ​​the urban pipe network as soon as possible. Taking measures should be able to alleviate the rainwater level, but after the first rain sensor receives the signal, it means that the rainwater has exceeded the planting layer and has reached the overflow state. At this time, if the diversion has been adjusted before, it means that the previous diversion measures cannot prevent the increase of the accumulated water level of rainwater, and it is necessary to make timely preparations for flood control. The first sensor and the second sensor can sense rainwater in stages, which is convenient for pipe network regulation. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] In a further embodiment, Figure 1 , Figure 2 , Figure 5 , Fig. 9As shown, a water replenishment component 600 for replenishing water into the space formed by the third baffle 504 and the fourth baffle 505 is arranged on the wall of the wellbore 201, and the water replenishment component 600 includes a straight and curved water replenishment pipe 601, and the horizontal section of the water replenishment pipe 601 is connected to the water pump 606 in the pump well 108, and a nozzle 603 is arranged on the wall of the horizontal section of the water replenishment pipe 601, and a nozzle 605 is arranged at the top of the nozzle 603, and a throttle port 602 is arranged in the horizontal section of the water replenishment pipe 601, and the throttle port 602 is located between the vertical section of the water replenishment pipe 601 and the nozzle 603, and the vertical section of the water replenishment pipe 601 is located in the wellbore 201, and the lower end of the vertical section of the water replenishment pipe 601 is provided with a valve assembly 700 for opening and closing it.

[0073] In a further embodiment, Figure 6 As shown, the valve assembly 700 includes a second guide sleeve 701, which is fixed in the vertical section of the water supply pipe 601 by a fixing rod 702, and a second guide rod 703 is vertically slid in the second guide sleeve 701, and the upper end of the second guide rod 703 is provided with a limit block 704 to prevent it from escaping from the second guide sleeve 701, and the lower end of the second guide rod 703 is provided with a second float 705 for switching the lower end of the pipe mouth of the vertical section of the water supply pipe 601, and the lower end of the second float 705 is lower than the upper end of the fourth baffle 505 when it closes the water supply pipe 601, and the upper end of the second float 705 is provided with a sealing gasket 706 that cooperates with the lower end of the vertical section of the water supply pipe 601.

[0074] In a further embodiment, Figure 7 As shown, the valve assembly 700 includes a second guide sleeve 701, a floating water chamber 709 and a solenoid valve 711. The second guide sleeve 701 is fixed in the vertical section of the water supply pipe 601 through a fixing rod 702. A second guide rod 703 slides vertically in the second guide sleeve 701. The upper end of the second guide rod 703 is provided with a limit block 704 to prevent it from escaping from the second guide sleeve 701. The lower end of the second guide rod 703 is provided with a second floating block 705 for opening and closing the lower end of the pipe opening of the vertical section of the water supply pipe 601. The upper end of the second floating block 705 is provided with a sealing gasket 706 that cooperates with the lower end of the vertical section of the water supply pipe 601 and a first magnet 707 that cooperates with the second magnet 708 on the outer side of the lower end of the vertical section of the water supply pipe 601. The floating water chamber 709 is arranged at the lower end of the water supply pipe 601 and wraps the second floating block 705. The lower end of the floating water chamber 709 is provided with a water outlet pipe 710. The lower end of the water outlet pipe 710 is lower than the upper end of the fourth baffle 505. The solenoid valve 711 is arranged on the nozzle 603.

[0075] The present invention can achieve long-term low-water-level overflow by staggering the six first grates 303 and the six second grates 313 in the slag blocking assembly 300, ensuring that the outer side of the overflow well mouth is in a low-water-level state for a long time to facilitate overflow and drainage. When a lot of slag is accumulated on the first grates 303 in the low-water-level overflow state, the housing drives all the first grates 303 to swing up through the lever 309 on the seat plate 403 to clean the slag. While cleaning the slag on the first grates 303, the six second grates 313 are still in a state of overflowing the surrounding accumulated water without affecting the overflow, thereby ensuring the overflow efficiency. The overflow well assembly 200 in the present invention can effectively prevent the increasing amount of water in the wellbore 201 from flowing back toward the wellhead through the odor-isolating and anti-reversal assembly 500 when the drainage flow rate of the drainage pipe 205 at the lower end of the wellbore 201 is less than the water inlet flow rate of the connecting pipe 206, ensuring that the water flowing through the drainage pipe 205 of the overflow well connected nearby can be discharged smoothly through the underground pipe network. After the drainage peak of the underground pipe network has passed, the odor-isolating and anti-reversal assembly 500 automatically opens and maintains the smooth discharge of the overflow water at the wellhead. The odor-isolating and anti-reversal assembly 500 of the overflow well assembly 200 in the present invention can automatically close and effectively isolate the bottom of the well from the outside when it is not overflowing and draining, preventing the stench generated by the bottom of the well being in a humid state for a long time from escaping upward through the wellhead, ensuring that the air around the wellhead of the overflow well is always clear, so that people sitting on the seat plate 403 have a better rest experience, and the odor-isolating and anti-reversal assembly 500 does not have the risk of failure, has the characteristics of long-term continuous function, and has low maintenance costs. The water replenishment component 600 in the present invention can regularly replenish water for the odor-isolating and anti-reversal component 500 that can form a water seal. The water replenishment component 600 can automatically close after the odor-isolating and anti-reversal component 500 is filled with enough water, thereby reducing water waste and achieving the purpose of saving water resources. The street lamp component 800 in the present invention is connected to the drain pipe 205 at the lower end of the shaft 201 of the overflow well component 200, through the vertically spaced circular rings 802 in the hollow lamp pole 801 and the water-absorbing annular sponge 803 arranged between the adjacent circular rings 802, so that the lower animals entering the drain pipe 205 can escape from the predicament upward through the top rod. At the same time, the annular sponge 803 in the lamp pole 801 can effectively absorb water and prevent the water in the drain pipe 205 from being discharged upward through the lamp pole 801 without blocking the passage of small animals, thereby ensuring that all the water in the drain pipe 205 is effectively discharged through the underground pipe network. In the present invention, a drain port 202 is provided on the wall of the wellbore 201 of the overflow well assembly 200. The drain port 202 is located in the planting layer 106 and a fine sand annular belt 111 and a coarse sand annular belt 112 are provided around the drain port 202 to filter the accumulated water from the planting layer 106 entering the wellbore 201, thereby preventing the plant roots in the planting layer 106 from rotting or drowning due to excessive water accumulation. At the same time, the accumulated water in the planting layer 106 is prevented from carrying a large amount of debris into the wellbore 201 through the drain port 202, thereby causing blockage of the wellbore 201 after long-term use, thereby effectively reducing the maintenance cost of the overflow well assembly 200.

[0076] The operation process of the present invention is as follows:

[0077] In the initial state, the first grate 303 in the slag blocking assembly 300 swings down to the limit and forms an upper-opening grate cage with the corresponding fifth grate 318 and the two third grates 315, and the free end of the lever 309 is in an upward state. If the odor isolation and anti-reversal assembly 500 switches the S channel formed by the first baffle 501, the second baffle 502, the third baffle 504 and the fourth baffle 505 through the first floating block 506, then the bottom of the first floating block 506 abuts against the limit bar 503 and closes the channel between the second baffle 502 and the fourth baffle 505, and the upper end of the fourth baffle 505 is slightly higher than the lower end of the first floating block 506. If the odor-isolating and anti-reversal component 500 switches the S channel formed by the first baffle 501, the second baffle 502, the third baffle 504 and the fourth baffle 505 by water sealing, the water surface on the third baffle is flush with the upper end of the fourth baffle 505, and the lower end of the second baffle 502 is lower than the water surface. If a floating water cavity 709 is provided at the end of the water supply pipe 601, the lower end of the outlet pipe 710 of the valve component 700 is lower than the water surface and the second floating block 705 of the valve component 700 closes the water supply pipe 601, the first magnet 707 and the second magnet 708 are attracted together, and the floating water cavity 709 and the outlet pipe 710 are filled with water. If a floating water cavity 709 is not provided at the end of the water supply pipe 601, the lower end of the second floating block 705 of the valve component 700 is lower than the water surface and closes the water supply pipe 601.

[0078] When it rains moderately, the water storage in the gravel layer 103 reaches its limit and spreads to the planting layer 106. Most of the water reaching the planting layer 106 will enter the wellbore 201 through the filtration of the coarse sand annulus 112 and the fine sand annulus 111 at the drain port 202. At this time, the second rain sensor 901 can sense it and transmit it to the cloud platform for detection and warning. At this time, the odor isolation and anti-reverse component 500 located below the drain port 202 in the wellbore 201 does not form a barrier to the water entering the wellbore 201 through the drain port 202. The water entering the wellbore 201 from the planting layer 106 through the drain port 202 is effectively discharged, thereby avoiding water accumulation in the planting layer 106 and causing the vegetation 113 to rot or drown.

[0079] like Figure 8As shown, in the process of water entering the wellbore 201 from the drain port 202 passing through the odor isolation and anti-reversal component 500, if the odor isolation and anti-reversal component 500 switches the channel between the second baffle 502 and the fourth baffle 505 through the first float 506, then when the water reaches the third baffle 504 and the liquid surface begins to contact the first float 506, the first float 506 moves upward under the action of buoyancy and opens the channel between the second baffle 502 and the fourth baffle 505, passing through the odor isolation and anti-reversal component The water reaching the bottom of the shaft 201 passes through the drainage pipe 205 and reaches the underground drainage system or the bottom of the adjacent shaft 201. Since the drainage pipe 205 and the connecting pipe 206 at the lower end of the shaft 201 are spaced a certain distance from its bottom, the water coming in from the adjacent shaft 201 through the connecting pipe 206 will form turbulence at the bottom of the shaft 201, thereby reducing the flow rate of the water coming in from the adjacent shaft 201, and further reducing the impact of the water flow, making it easier for the water at the bottom of the shaft 201 to be discharged smoothly through the drainage pipe 205. When most of the water in the planting layer 106 enters the wellbore 201 through the drain port 202 and is discharged, the accumulated water on the third baffle 504 will form a relatively fragile water seal because the upper end of the fourth baffle 505 is slightly higher than the lower end of the second baffle 502. The first floating block 506 falls on the water surface, and the water seal can temporarily block the odor at the bottom of the wellbore 201 from reaching the wellhead and polluting the environment. When the water plane in the water seal is lower than the lower end of the second baffle 502 due to evaporation, the first floating block 506 will reset as the water surface drops and close the channel between the second baffle 502 and the fourth baffle 505, ensuring that the odor isolation and anti-reversal component 500 continues to perform its odor isolation function.

[0080] When it rains heavily, the water storage in the gravel layer 103 and the planting layer 106 reaches the limit, and the water in the planting pool 101 floods the covering layer 107 and passes over the ground ring 204 and enters the wellbore 201 through the six first grates 303 in a downward swing state and the third grates 315 on both sides of the first grates 303. When the water entering the wellbore 201 from the wellhead reaches the third baffle 504 and the liquid surface begins to contact the first float 506, the first float 506 moves upward under the action of buoyancy and opens the channel between the second baffle 502 and the fourth baffle 505. The water that reaches the bottom of the wellbore 201 through the odor isolation and anti-reverse assembly 500 reaches the underground drainage system or reaches the bottom of the adjacent wellbore 201 through the drain pipe 205. When a lot of scum is accumulated on the first grates 303, the lever 309 is pressed down, and the lever 309 drives all the first grates 303 to swing up to the limit through the slide bar 307, the frame 306, and the driving rod 305, and forms a complete cone surface with the six second grates 313, which is conducive to cleaning the scum on the first grates 303.

[0081] When the water flow from the adjacent wellbore 201 through the connecting pipe 206 at the bottom of the wellbore 201 reaches its limit, the drain pipe 205 cannot complete the drainage in time, and the water at the bottom of the wellbore 201 rises rapidly. When the water surface reaches the first baffle 501 of the odor isolation and anti-reverse flow component 500, the first floating block 506 will keep the channel between the second baffle 502 and the fourth baffle 505 closed under the action of water pressure, thereby achieving the purpose of blocking backflow.

[0082] like Figure 6 As shown, when it rains moderately, in the process of water entering the wellbore 201 from the drain port 202 and passing through the odor isolation and anti-reversal component 500, if the odor isolation and anti-reversal component 500 blocks the connection between the bottom of the wellbore 201 and the wellhead by the principle of water sealing through the water stored on the third baffle plate 504 and the floating water chamber 709 is not provided at the end of the water supply pipe 601 of the corresponding water supply component 600, then when the water reaches the water seal on the third baffle plate 504, the water in the water seal will overflow to the bottom of the wellbore 201 through the fourth baffle plate 505, thereby achieving the water reaching the bottom of the wellbore 201 through the odor isolation and anti-reversal component 500 and being discharged from the drain pipe 205 to the underground drainage system. When most of the water in the planting layer 106 enters the wellbore 201 through the drain port 202 and is discharged, the accumulated water on the third baffle 504 will form an effective water seal similar to that in a toilet because the upper end of the fourth baffle 505 is higher than the lower end of the second baffle 502. The lower end of the second float 705 in the water replenishment component 600 is a certain distance below the water surface. The water seal can effectively prevent the odor at the bottom of the wellbore 201 from reaching the wellhead and polluting the environment. When the water level in the water seal is lower than the lower end of the second baffle 502 due to evaporation, the second float 705 loses the buoyancy of the water and falls under its own weight and opens the water supply pipe 601. At this time, the water pump 606 in the pump well 108 supplies water to the third baffle 504 through the water supply pipe 601 and makes the water surface on the third baffle 504 flush with the upper end of the fourth baffle 505, thereby forming a water seal between the second baffle 502 and the fourth baffle 505. The second float 705 closes the water supply pipe 601 under the action of buoyancy to achieve the purpose of not wasting water resources while ensuring that the odor isolation and anti-reversal component 500 continues to perform its odor isolation function. During the water replenishment process, the water pumped into the water replenishment pipe 601 by the water pump 606 first reaches the nozzle 605 through the nozzle 603 to be sprayed out to irrigate the vegetation 113, and then reaches the second floating block 705 through the throttle port 602 in the water replenishment pipe 601. The throttle port 602 in the water replenishment pipe 601 can effectively reduce the water speed and make the water pressure on the upper surface of the second floating block 705 smaller without pushing open the second floating block 705 in the closed state, thereby ensuring that the water seal formed in the odor isolation and anti-reverse assembly 500 will not continuously overflow into the wellbore 201, thereby saving water resources.

[0083] When it rains heavily, the water storage in the gravel layer 103 and the planting layer 106 reaches the limit, and the water in the planting pool 101 floods the covering layer 107 and passes over the ground ring 204, and flows into the wellbore 201 through the six first grates 303 in the downward swing state and the third grates 315 on both sides of the first grates 303. When the water entering the wellbore 201 from the wellhead reaches the water seal on the third baffle 504, the first rain sensor 902 senses the rainwater during this process and transmits it to the cloud platform, which plays a warning and early warning role. At this time, the water in the water seal will overflow to the bottom of the wellbore 201 through the fourth baffle 505. The water that reaches the bottom of the wellbore 201 through the odor isolation and anti-reverse assembly 500 reaches the underground drainage system or reaches the bottom of the adjacent wellbore 201 through the drain pipe 205. When a lot of scum is accumulated on the first grates 303, the lever 309 is pressed down, and the lever 309 drives all the first grates 303 to swing up to the limit through the slide bar 307, the frame 306, and the driving rod 305, and forms a complete cone surface with the six second grates 313, which is conducive to cleaning the scum on the first grates 303.

[0084] When the water flow from the adjacent wellbore 201 through the connecting pipe 206 at the bottom of the wellbore 201 reaches its limit, the drain pipe 205 cannot complete the drainage in time, and the water at the bottom of the wellbore 201 rises rapidly. When the water surface reaches the third baffle 504 of the odor isolation and anti-reverse flow assembly 500, the third baffle 504 will rise under the action of water pressure and resist against the lower end of the second baffle 502, so that the odor isolation and anti-reverse flow assembly 500 is closed, thereby achieving the purpose of blocking backflow.

[0085] like Figure 7As shown, when it rains moderately, in the process of water entering the wellbore 201 from the drain port 202 and passing through the odor isolation and anti-reversal component 500, if the odor isolation and anti-reversal component 500 blocks the connection between the bottom of the wellbore 201 and the wellhead by the principle of water sealing through the water stored on the third baffle plate 504 and a floating water cavity 709 is provided at the end of the water supply pipe 601 of the corresponding water supply component 600 to wrap the second floating block 705, then when the water reaches the water seal on the third baffle plate 504, the water in the water seal will overflow to the bottom of the wellbore 201 through the fourth baffle plate 505, thereby achieving the water reaching the bottom of the wellbore 201 through the odor isolation and anti-reversal component 500 and being discharged from the drain pipe 205 to the underground drainage system. When most of the water in the planting layer 106 enters the wellbore 201 through the drain port 202 and is discharged, the accumulated water on the third baffle 504 will still form an effective water seal similar to that in a toilet because the upper end of the fourth baffle 505 is higher than the lower end of the second baffle 502. The second float 705 in the water replenishment component 600 is in a closed state to the water replenishment pipe 601 under the action of the first magnet 707 and the second magnet 708. The water seal on the third baffle 504 effectively blocks the odor at the bottom of the wellbore 201 from reaching the wellhead and polluting the environment. When the water level in the water seal is lower than the lower end of the second baffle 502 due to evaporation, the water seal fails, and the bottom of the wellbore 201 is connected to the wellhead. At this time, water is pumped into the water supply pipe 601 by the water pump 606 in the pump well 108. The water pumped into the water supply pipe 601 by the water pump 606 reaches the solenoid valve 711 through the nozzle 603 and reaches the second float 705 through the throttle port 602. The throttle port 602 decelerates the water flow and effectively reduces the pressure of the water flow on the second float 705, and cannot overcome the suction of the first magnet 707 and the second magnet 708. The second float 705 is still in a closed state. At this time, the solenoid valve 711 is briefly opened and closed, so that the water in the nozzle 603 produces pulsation similar to the water hammer effect and is transmitted to the second float 705 through the water supply pipe 601, effectively overcoming the first magnet 707 and the second magnet 708. The suction force causes the second floating block 705 to instantly open the water supply pipe 601, and the water in the water supply pipe 601 enters the floating water chamber 709. The water in the floating water chamber 709 reaches the third baffle 504 through the outlet pipe 710 and finally forms a water seal. In the process of the water supply pipe 601 replenishing water to the third baffle 504, since the water output of the outlet pipe 710 is four-fifths of the water output of the water supply pipe 601 and the water capacity of the floating water chamber 709 is one-fifth of the water output of the water supply pipe 601, the original water on the third baffle 504 is replaced while the floating water chamber 709 replenishes water to the third baffle 504 through the outlet pipe 710, thereby achieving the goal of replenishing water on the third baffle 504 to re-form a water seal while partially replacing the original smelly water on the third baffle 504, fundamentally solving the problem of odor in the overflow well.

[0086] After the second floating block 705 is opened, the solenoid valve 711 is immediately opened again, and the water in the water supply pipe 601 reaches the nozzle 605 through the nozzle 603 and sprays out to irrigate the vegetation 113. The throttle port 602 in the water supply pipe 601 can effectively reduce the water speed and make the water pressure on the upper surface of the second floating block 705 smaller, and will not push the second floating block 705 in the closed state open, ensuring that the water seal formed in the odor isolation and anti-reversal component 500 will not continuously overflow into the wellbore 201, saving water resources. When the floating water chamber 709 is just full of water, the water level on the third baffle 504 is just flush with the upper end of the fourth baffle 505. The second floating block 705 closes the water supply pipe 601 under the buoyancy of the water in the floating water chamber 709 and the interaction between the first magnet 707 and the second magnet 708, saving water resources and avoiding water waste.

[0087] When it rains heavily, the water storage in the gravel layer 103 and the planting layer 106 reaches the limit, and the water in the planting pool 101 floods the covering layer 107 and passes over the ground ring 204, and flows into the wellbore 201 through the six first grates 303 in a downward swing state and the third grates 315 on both sides of the first grates 303. When the water entering the wellbore 201 from the wellhead reaches the water seal on the third baffle 504, the water in the water seal will overflow to the bottom of the wellbore 201 through the fourth baffle 505. The water that reaches the bottom of the wellbore 201 through the odor isolation and anti-reverse assembly 500 reaches the underground drainage system or reaches the bottom of the adjacent wellbore 201 through the drain pipe 205. When a lot of scum is accumulated on the first grates 303, the lever 309 is pressed down, and the lever 309 drives all the first grates 303 to swing up to the limit through the slide bar 307, the frame 306, and the driving rod 305, and forms a complete cone surface with the six second grates 313, which is conducive to cleaning the scum on the first grates 303.

[0088] When the water flow from the adjacent wellbore 201 through the connecting pipe 206 at the bottom of the wellbore 201 reaches its limit, the drain pipe 205 cannot complete the drainage in time, and the water at the bottom of the wellbore 201 rises rapidly. When the water surface reaches the third baffle 504 of the odor isolation and anti-reverse flow assembly 500, the third baffle 504 will rise under the action of water pressure and resist against the lower end of the second baffle 502, so that the odor isolation and anti-reverse flow assembly 500 is closed, thereby achieving the purpose of blocking backflow.

[0089] The annular sponge 803 in the lamp pole 801 of the street lamp assembly 800 will absorb a lot of water during the drainage process of the drain pipe 205 and effectively block the water from moving outward through the lamp pole 801. Normally, if small animals enter the drain pipe 205, the small animals can climb up through the circular ring 802 in the lamp pole 801. During the climbing process, the small animals can squeeze the sponge 803 and get out from the middle of the sponge 803.
