Description

Technical Field

[0001] This invention relates to the field of road ancillary structures, and more specifically to a rainwater inlet with an odor-proof diversion structure and a diversion method. Background Technology

[0002] A storm drain is a structure that collects rainwater in storm drains or combined sewer systems. Rainwater from the street surface first passes through the storm drain and flows into the drainage system via connecting pipes. The form, number, and arrangement of storm drains should be determined based on the catchment area, the drainage capacity of the storm drains, and the road type. The location of the storm drains should ensure the rapid and effective collection of surface rainwater.

[0003] Chinese invention patent application CN110512711B, or Chinese invention patent application number for a concealed odor-proof rainwater inlet, includes a housing. The left half of the housing is a rainwater inlet, and the right half is a control component housing. Multiple longitudinal sleeves are arranged circumferentially along the inner wall of the rainwater inlet. Each sleeve contains a spring-connected rod, which is connected to a cover plate. The lower surface of the cover plate has a fixed end connected to one end of a cable. The other end of the cable is connected to a cable winding wheel, which is connected to the output shaft of a stepper motor. The stepper motor is connected to a microprocessor, which is also connected to a rainwater detector and a smart lock. The stepper motor, microprocessor, and smart lock are all electrically connected to a power module, which is connected to the municipal road power supply system. This invention can be concealed under the road surface, preventing odors and garbage accumulation, and automatically opens to quickly drain rainwater during rainy weather.

[0004] However, the aforementioned devices still have certain drawbacks. With rapid urban development, the increasing number of paved roads leads to increased rainwater runoff, and the initial runoff is severely polluted. This initial rainwater dissolves large amounts of acidic gases, vehicle exhaust, factory emissions, and other pollutants from the air. After falling to the ground, it washes over roofs and asphalt concrete roads, resulting in a high level of pollution, sometimes exceeding that of ordinary urban sewage. Such rainwater is unsuitable for direct discharge and requires sewage treatment before release. In extreme rainfall conditions, direct discharge from rainwater inlets can overload the entire rainwater drainage system for a period, causing overflows and preventing timely drainage of road surface water, leading to urban flooding. To address urban flooding, sponge city construction, stormwater storage tank construction, and upgrading of rainwater pipe systems can be implemented, but these projects are large-scale and costly.

[0005] Therefore, it is necessary to invent a rainwater inlet with an odor-proof diversion structure and a diversion method to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a rainwater inlet and diversion method with an odor-proof diversion structure, which can achieve staggered discharge during heavy rain. The M-shaped overflow pipe and siphon inlet can be modified according to the actual situation, so as to reduce the peak flow of the drainage pipe in the drainage well during extreme rainy days, thereby solving the problem of waterlogging caused by insufficient drainage capacity of urban drainage wells in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a rainwater inlet device with an odor-proof and diversion structure, comprising a drainage well, wherein the inner cavity of the drainage well is provided with a hollow overflow cylinder with an open top, a fixing ring is bolted to the inner side of the upper part of the overflow cylinder's inner cavity, a guide ring is snapped onto the top of the fixing ring, a connecting rod is bolted to the bottom of the guide ring, a intercepting groove is bolted to the inner side of the connecting rod, a sewage tank is slidably connected inside the intercepting groove, and spring grooves are provided around the bottom of the sewage tank and the bottom of the intercepting groove's inner cavity, with springs bolted to the inner side of each spring groove. Both sides of the bottom of the water tank cavity are hinged with linkage rods. A through groove is opened in the middle of the inner cavity of the guide ring. Linkage plates are hinged to the front and back of both sides of the through groove, and the bottom of the linkage plate is hinged to the top of the linkage rod. Overflow components are opened on both sides of the inner cavity of the guide ring. An anti-backflow component is set in the middle of the inner cavity of the overflow cylinder. A water collection frame is bolted to the top of the inner side of the drainage well. A rain grate is snapped into the top of the inner side of the water collection frame. An odor prevention mechanism is opened in the middle of the inner side of the water collection frame. A baffle plate is bolted to the lower part of the inner cavity of the overflow cylinder. An M-shaped overflow pipe is bolted to the right side of the baffle plate.

[0008] In a preferred embodiment of the present invention, the overflow assembly includes an overflow trough. Sealing plates are hinged to both sides of the inner cavity of the guide ring. First rubber sealing blocks are bolted to both sides of the bottom of the sealing plates. Second rubber sealing blocks are bolted to both sides of the inner cavity of the guide ring, and the surfaces of the first and second rubber sealing blocks are interlocked. Foam floats are bolted to the top of the sealing plates. The upper part of the sealing plates is rotatably hinged to the inner side of the guide ring. When rainwater submerges the sealing plates and the upper foam floats, due to buoyancy, the foam floats will cause the left side of the sealing plates to rise until the overflow trough is opened. Simultaneously, when the sealing plates are closed, the first rubber sealing blocks cooperate with the second rubber sealing blocks to seal the overflow trough, preventing water from entering. Preferably, the anti-backflow assembly includes a locking ring, and the outer side of the locking ring is bolted to the inner side of the middle of the overflow cylinder cavity. A partition plate is bolted to the inner side of the locking ring. A limit rod is bolted to the left side of the top of the partition plate. A slider is slidably connected to the surface of the limit rod. A folded rod is bolted to the right side of the slider. A drainage groove is opened on the left side of the partition plate, and a float is bolted to the bottom of the folded rod through the drainage groove. When rainwater enters the drainage groove and accumulates on the top of the barrier plate, the float is affected by buoyancy and moves vertically upward under the limit of the limit rod through the slider and the folded rod. The upper part of the paper float blocks and seals the opening of the drainage groove, so that the water flow under the partition plate cannot overflow. Preferably, the odor-proof mechanism includes a rotating rod, rectangular grooves are provided on both sides of the water collection frame, the front and rear of the rectangular grooves are rotatably connected to the front and rear sides of the rotating rod through bearings, baffles are bolted to the front and rear of the inner side of the rotating rod, a limit strip is bolted to the upper part of the inner side of the rectangular groove, and a torsion spring is bolted to the middle of the surface of the rotating rod, with the two ends of the torsion spring respectively engaging with the bottom of the baffle and the inner wall of the rectangular groove. Under normal circumstances, the baffles are closed to prevent odorous gases from leaking out of the overflow cylinder cavity. After rainwater drips onto the baffle through the rain grate and accumulates, the weight of the rainwater accumulates to a point greater than the torsional force of the torsion spring, so the left side of the baffle moves downward in an arc shape, allowing the rainwater to fall into the guide bucket. Subsequently, due to the loss of the weight of the accumulated rainwater, the torsion spring resets the baffle again through its own torsional force, and the limit strip assists the baffle in returning to its original position. Preferably, rubber strips are bolted to the inner side of the linkage plate, a sewage hose is connected to the center of the bottom of the sewage tank, a hose groove is opened at the center of the bottom of the interception tank, and the other end of the sewage hose passes through the hose groove and the left side of the overflow cylinder. The rubber strips can help the linkage plate seal the bottom of the guide ring after closing. The sewage hose can drain the rainwater in the sewage tank, and the hose groove can facilitate the user to adjust the specifications of the hose. Preferably, magnetic attractors are bolted to the bottom perimeter of the intercepting trough and the bottom perimeter of the sewage tank. The top and bottom of the magnetic attractors are positive and negative poles, respectively. When they are in contact, they can be attracted together by magnetic force, thereby increasing the flow rate of sewage in the sewage tank and the intercepting trough. Preferably, the bottom of the inner cavity of the sewage tank is lined with an absorbent sponge, so that rainwater can be absorbed by the absorbent sponge as soon as it enters the sewage tank, and the initial weight of the rainwater in the sewage tank is increased. Preferably, a guide bucket is bolted to the upper part of the overflow cylinder cavity, and support rods are bolted to all four sides of the bottom of the guide bucket. The other end of the support rod is bolted to the inner wall of the overflow cylinder cavity, so that the support rod fixes the guide bucket to the upper part of the overflow cylinder cavity. Preferably, the bottom left side of the overflow cylinder is connected to a rainwater pipe, so that the rainwater accumulated in the overflow cylinder can be discharged through the rainwater pipe.

[0009] A method for diverting water with an odor-proof diversion structure includes a rainwater inlet device with an odor-proof diversion structure as described above, and the specific processing steps are as follows: Step 1: On a sunny day, the device is in its first state, as shown in the figure. The guide bucket will guide the water flowing through the rain grate into the sewage tank in the intercepting channel. When there is too much water in the sewage tank, the sewage tank will gradually move towards the bottom of the intercepting channel due to the gravity of the internal water flow, until the sewage tank is connected to the bottom of the intercepting channel through the magnetic attraction. At this time, the sewage in the sewage tank will be gradually discharged through the sewage hose. After the water in the sewage tank is discharged, the overall weight gradually decreases, and the spring will continuously push the sewage tank upward through its own elastic force. When the elastic force is greater than the magnetic force of the magnetic attraction and the downward gravity of the sewage tank, the spring will assist the sewage tank to reset. At this time, the overflow channel and the M-shaped overflow pipe are both in the closed state. Step Two: During rainy weather, the interception trough still serves to intercept the initial runoff of rainwater. Since the rainwater in the early stages of rainy weather comes into contact with the ground first and is more polluted, this part of the rainwater is initially diverted through the interception components. When the sewage tank moves downward, it will drive the linkage plate to move downward in an arc shape through the linkage rod until the other end of the linkage plate closes together and is sealed by the rubber strip. At this time, the bottom of the guide ring is in a sealed state. Rainwater from the middle to the later stages of rainy weather will fall into the inner cavity of the guide ring until the rainwater accumulates and submerges the sealing plate. The foam float on the top of the sealing plate will drive the sealing plate to rise, causing the overflow trough to open. At this time, the rainwater will pass through the overflow trough and fall into the top of the barrier plate through the drainage trough, and collect in the lower part of the overflow cylinder inner cavity, intercepting this part of the rainwater and completing the secondary diversion. Step 3: When rainwater accumulates above the M-shaped overflow pipe opening at the top of the baffle plate, the M-shaped overflow pipe uses the siphon effect to draw the rainwater above the pipe opening to the bottom of the overflow cylinder. Finally, this part of the rainwater will be discharged from the overflow cylinder through the rainwater pipe, completing the third diversion. At the same time, the rainwater is collected by the baffle plate, which allows some rainwater to be temporarily stored inside the overflow cylinder, reducing the pressure on the urban drainage system when heavy rain comes. Step 4: When heavy rain occurs and the rainwater flow in the overflow cylinder is too large, in order to prevent the rainwater between the partition plate and the baffle plate from flowing back to the upper part of the overflow cylinder, the accumulation of rainwater on the top of the baffle plate will cause the float to gradually rise. It will then move vertically upward on the surface of the limit rod through the folded rod and the slider until the upper part of the float blocks the drainage channel. This makes the space between the partition plate and the guide ring a second rainwater storage area. Since the space between the baffle plate and the partition plate is larger, more rainwater can be stored. The buoyancy of the float is greater than the pressure of the rainwater on the float from the top, which allows the float to stably seal the drainage channel. After the rainwater in the lower part is discharged through the M-shaped overflow pipe, the float descends and the drainage channel reopens. Through this final diversion, a multi-layer buffering effect can be achieved to prevent a large amount of rainwater from entering the drainage well.

[0010] Compared with the prior art, the technical effects and advantages provided by the present invention in the above technical solution are as follows: The initial rainwater runoff is intercepted and stored by components such as linkage rods and linkage plates between the interception trough and the sewage trough. The initial rainwater runoff is then transported to the sewage treatment plant for unified treatment through sewage hoses. This separates the highly polluted initial runoff from the middle and later runoff, effectively reducing the sewage treatment load in the urban rainwater pipe network and thus preventing highly polluted rainwater from entering the river and lake system. The M-shaped overflow pipe allows for segmented discharge of rainwater between the baffle and the partition. Combined with anti-backflow components, it creates another temporary rainwater storage area between the partition and the guide ring. Since rainwater only undergoes a siphon effect after submerging the M-shaped overflow pipe opening, the overflow cylinder can simultaneously store rainwater in two locations. This allows for staggered discharge during heavy rains. Furthermore, the M-shaped overflow pipe and siphon inlet can be modified according to actual conditions, reducing the peak flow of the drainage system during extreme rainy days and mitigating urban flooding caused by insufficient drainage capacity.

Detailed Implementation

[0014] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0015] This invention provides, for example Figure 1-7 The rainwater inlet device shown includes a drainage well 1. The drainage well 1 has a hollow overflow cylinder 2 with an open top. A fixing ring 3 is bolted to the inner side of the upper part of the overflow cylinder 2. A guide ring 4 is snapped onto the top of the fixing ring 3. A connecting rod 5 is bolted to the bottom of the guide ring 4. A intercepting groove 6 is bolted to the inner side of the connecting rod 5. A sewage tank 7 is slidably connected inside the intercepting groove 6. Spring grooves 8 are provided around the bottom of the sewage tank 7 and the bottom of the intercepting groove 6. Springs 9 are bolted to the inner sides of the spring grooves 8. Linkage rods 1 are hinged to both sides of the bottom of the sewage tank 7. 0. A through groove 11 is provided in the middle of the inner cavity of the guide ring 4. A linkage plate 12 is hinged to both the front and rear sides of the through groove 11, and the bottom of the linkage plate 12 is hinged to the top of the linkage rod 10. An overflow component 13 is provided on both sides of the inner cavity of the guide ring 4. An anti-backflow component 14 is provided in the middle of the inner cavity of the overflow cylinder 2. A water collection frame 15 is bolted to the top of the inner side of the drainage well 1. A rain grate 16 is snapped into the top of the inner side of the water collection frame 15. An odor prevention mechanism 17 is provided in the middle of the inner side of the water collection frame 15. A baffle plate 18 is bolted to the lower part of the inner cavity of the overflow cylinder 2. An M-shaped overflow pipe 19 is bolted to the right side of the baffle plate 18.

[0016] As a further optimization of the present invention, the overflow assembly 13 includes an overflow groove 131. Sealing plates 132 are hinged to both sides of the inner cavity of the guide ring 4. First rubber sealing blocks 133 are bolted to both sides of the bottom of the sealing plates 132, and second rubber sealing blocks 134 are bolted to both sides of the inner cavity of the guide ring 4. The surfaces of the first and second rubber sealing blocks 133 and 134 are interlocked. Foam floats 135 are bolted to the top of the sealing plates 132. The upper part of the sealing plates 132 is rotatably hinged to the inner side of the guide ring 4. When rainwater submerges the sealing plates 132 and the upper foam floats 135, due to buoyancy, the foam floats 135 will cause the left side of the sealing plates 132 to rise until the overflow groove 131 is opened. Simultaneously, when the sealing plates 132 are closed, the first rubber sealing blocks 133 cooperate with the second rubber sealing blocks 134 to seal the overflow groove 131, preventing water from entering.

[0017] like Figure 1 and Figure 2 As shown, the anti-backflow assembly 14 includes a locking ring 141, and the outer side of the locking ring 141 is bolted to the inner side of the middle of the overflow cylinder 2. A partition plate 142 is bolted to the inner side of the locking ring 141. A limit rod 143 is bolted to the left side of the top of the partition plate 142. A slider 144 is slidably connected to the surface of the limit rod 143. A folded rod 145 is bolted to the right side of the slider 144. A drainage groove 146 is provided on the left side of the partition plate 142. A float 147 is bolted to the bottom of the folded rod 145 through the drainage groove 146. When rainwater enters the drainage groove 146 and accumulates on the top of the barrier plate 18, the float 147 is affected by buoyancy and moves vertically upward under the limit of the limit rod 143 through the slider 144 and the folded rod 145. The upper part of the paper float 147 blocks and seals the opening of the drainage groove 146, preventing the water flow at the bottom of the partition plate 142 from overflowing.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the odor-proof mechanism 17 includes a rotating rod 171. Rectangular grooves 172 are provided on both sides of the water collection frame 15. The front and rear ends of the rectangular grooves 172 are rotatably connected to the front and rear ends of the rotating rod 171 via bearings. Baffles 173 are bolted to the front and rear ends of the inner side of the rotating rod 171. A limit strip 174 is bolted to the upper part of the inner side of the rectangular groove 172. A torsion spring 175 is bolted to the middle of the surface of the rotating rod 171, and both ends of the torsion spring 175 are respectively engaged with the bottom of the baffle 173 and the inner wall of the rectangular groove 172. Under normal conditions, the baffles... The baffle 173 and the baffle 173 close together to prevent the leakage of odorous gas from the inner cavity of the overflow cylinder 2. After rainwater drips onto the baffle 173 through the rain grate 16 and accumulates, the weight of the rainwater accumulates to a point greater than the torsional force of the torsion spring 175. As a result, the left side of the baffle 173 moves downward in an arc shape, allowing the rainwater to fall into the guide hopper 25. Subsequently, due to the loss of the weight of the accumulated rainwater, the torsion spring 175 resets the baffle 173 again through its own torsional force. The limiting strip 174 can assist the baffle 173 in returning to its original position.

[0019] like Figure 1 , Figure 2 and Figure 7 As shown, rubber strips 20 are bolted to the inner side of the linkage plate 12. A sewage hose 21 is connected to the center of the bottom of the sewage tank 7. A hose groove 22 is opened at the center of the bottom of the interception tank 6. The other end of the sewage hose 21 passes through the hose groove 22 and the left side of the overflow cylinder 2. The rubber strips 20 can help the linkage plate 12 to seal the bottom of the guide ring 4 after closing. The sewage hose 21 can drain the rainwater in the sewage tank 7. The hose groove 22 can facilitate the user to adjust the specifications of the hose.

[0020] like Figure 1 , Figure 2 and Figure 5 As shown, magnetic components 23 are bolted to the bottom of the intercepting trough 6 and the bottom of the sewage tank 7. The top and bottom of the magnetic components 23 are positive and negative poles, respectively. When they are attached to each other, they can be attracted together by magnetic force, thereby increasing the flow rate of sewage in the sewage tank 7 and the intercepting trough 6.

[0021] like Figure 1 , Figure 2 and Figure 5 As shown, the bottom of the inner cavity of the sewage tank 7 is lined with a water-absorbing sponge 24, so that rainwater can be absorbed by the water-absorbing sponge 24 as soon as it enters the sewage tank 7, and the initial weight of the rainwater in the sewage tank 7 is increased.

[0022] like Figure 1 and Figure 2As shown, a guide bucket 25 is bolted to the upper part of the inner cavity of the overflow cylinder 2. Support rods 26 are bolted to all four sides of the bottom of the guide bucket 25, and the other end of the support rods 26 is bolted to the inner wall of the inner cavity of the overflow cylinder 2, so that the support rods 26 fix the guide bucket 25 to the upper part of the inner cavity of the overflow cylinder 2.

[0023] like Figure 1 and Figure 2 As shown, a rainwater pipe 27 is connected to the bottom left side of the overflow cylinder 2, so that the rainwater accumulated in the overflow cylinder 2 can be discharged through the rainwater pipe 27.

[0024] A method for diverting water with an odor-proof diversion structure includes a rainwater inlet device with an odor-proof diversion structure as described above, and the specific processing steps are as follows: Step 1: On a sunny day, the device is in its first state, such as... Figure 1 As shown, the guide bucket 25 guides the water flowing through the rain grate 16 into the sewage tank 7 in the intercepting channel 6. When there is too much water in the sewage tank 7, the sewage tank 7 gradually moves towards the bottom of the intercepting channel 6 due to the influence of the gravity of the internal water flow, until the sewage tank 7 is connected to the bottom of the intercepting channel 6 through the magnetic suction 23. At this time, the sewage in the sewage tank 7 will be gradually discharged through the sewage hose 21. After the water in the sewage tank 7 is discharged, the overall weight gradually decreases, and the spring 9 will continuously push the sewage tank 7 upward through its own elastic force. When the elastic force is greater than the magnetic force of the magnetic suction 23 and the downward gravity of the sewage tank 7, the spring 9 will assist the sewage tank 7 to reset. At this time, the overflow channel 131 and the M-shaped overflow pipe 19 are both in a closed state. Step 2: During rainy weather, the interception trough 6 still serves to intercept the initial runoff of rainwater. Since the rainwater in the early stage of rainy weather comes into contact with the ground first and is more polluted, this part of the rainwater is initially diverted through the interception component. When the sewage tank 7 moves downward, it will drive the linkage plate 12 to move downward in an arc shape through the linkage rod 10 until the other end of the linkage plate 12 is closed and sealed by the rubber strip 20. At this time, the bottom of the guide ring 4 is in a sealed state. The rainwater in the middle to late stages of rainy weather will fall into the inner cavity of the guide ring 4 until the rainwater accumulates and submerges the sealing plate 132. The foam float 135 on the top of the sealing plate 132 will drive the sealing plate 132 to float up, causing the overflow trough 131 to open. At this time, the rainwater will pass through the overflow trough 131 and fall into the top of the barrier plate 18 through the drainage trough 146, and gather in the lower part of the inner cavity of the overflow cylinder 2, intercepting this part of the rainwater and completing the secondary diversion. Step 3: When rainwater accumulates above the opening of the M-shaped overflow pipe 19 at the top of the baffle plate 18, the M-shaped overflow pipe 19 uses the siphon effect to draw the rainwater above the opening to the bottom of the overflow cylinder 2. Finally, this part of the rainwater will be discharged from the overflow cylinder 2 through the rainwater pipe 27, completing the third diversion. At the same time, the rainwater is collected by the baffle plate 18, which can temporarily store some rainwater inside the overflow cylinder 2, reducing the pressure on the urban drainage system when heavy rain comes. Step 4: When heavy rain occurs and the rainwater flow in the overflow cylinder 2 is too large, in order to prevent the rainwater between the partition plate 142 and the baffle plate 18 from flowing back to the upper part of the overflow cylinder 2, the accumulation of rainwater on the top of the baffle plate 18 will cause the float 147 to gradually float upwards. It will then move vertically upwards on the surface of the limit rod 143 through the folded rod 145 and the slider 144 until the upper part of the float 147 blocks the drainage channel 146, making the area between the partition plate 142 and the guide ring 4 a second rain... The water storage area, and because the space between the baffle plate 18 and the partition plate 142 is larger, can store more rainwater. The buoyancy of the float 147 is greater than the pressure of the rainwater on the float 147, which enables the float 147 to stably seal the drainage channel 146 until the rainwater in the lower part is discharged through the M-shaped overflow pipe 19. Then the float 147 descends, and the drainage channel 146 reopens. Through the final diversion, it can play a multi-layer buffering effect on the large amount of rainwater entering the drainage well 1.

[0025] Specific embodiments of the present invention, such as Figure 1-7 As shown: When using the device, as Figure 1As shown, the linkage plate 12 is in the open state. At this time, the initial runoff rainwater entering the overflow cylinder 2 will be affected by the guide bucket 25 and the guide ring 4, and enter the sewage tank 7. After the rainwater accumulates in the sewage tank 7, the weight gradually increases, and the sewage tank 7 gradually moves downward. During this process, the linkage rod 10 will drive the upper linkage plate 12 to gradually close in the middle due to the movement of the bottom. Finally, the magnetic suction part 23 will attract and connect the bottom of the sewage tank 7 and the intercepting channel 6, and the linkage plate 12 will be completely closed. The bottom of the guide ring 4 will be sealed, and the rainwater will begin to accumulate inside the guide ring 4 and gradually submerge the sealing plate 132. The foam float plate on the upper part of the sealing plate 132 will drive the inner side of the sealing plate 132 to move upward in an arc shape, opening the through slot 11. The intermediate runoff rainwater will enter the bottom of the overflow cylinder 2 through the drainage channel 146 and accumulate on the top of the barrier plate 18 until it submerges the M-shaped overflow. Pipe 19, the M-shaped overflow pipe 19, uses the siphon effect to draw rainwater that has exceeded the pipe opening to the lower part of the baffle plate 18. This part of the rainwater will be discharged to the outside of the overflow cylinder 2 through the rainwater pipe 27. The remaining rainwater is temporarily stored between the partition plate 142 and the baffle plate 18, which reduces the drainage pressure of the rainwater pipe 27 when the rainfall is large. When the rainwater accumulates on the top of the baffle plate 18, the buoyancy will lift the float 147, which will move vertically upward on the surface of the limit rod 143 through the folded rod 145 and the slider 144 until the float 147 blocks the drainage channel, so that the rainwater at the bottom cannot flow back to the top through the drainage channel. At the same time, the rainwater that re-enters will accumulate between the partition plate 142 and the guide ring 4, becoming a second rainwater storage place, waiting for the lower M-shaped overflow pipe 19 and the rainwater pipe 27 to discharge the water. The rainwater is diverted and discharged without the influence of any external active drive device.

[0026] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

10. A method for diverting water with an odor-proof diversion structure, comprising a rainwater inlet device with an odor-proof diversion structure as described in any one of claims 1-9, characterized in that: The specific processing steps are as follows: Step 1: On a sunny day, the guide bucket (25) will guide the water flowing through the rain grate (16) into the sewage tank (7) in the intercepting channel (6). When there is too much water in the sewage tank (7), the sewage tank (7) will gradually move towards the bottom of the intercepting channel (6) under the influence of the gravity of the internal water flow until the sewage tank (7) is connected to the bottom of the intercepting channel (6) through the magnetic suction (23). At this time, the sewage in the sewage tank (7) will be gradually discharged through the sewage hose (21). After the water in the sewage tank (7) is discharged, the overall weight gradually decreases. The spring (9) will continuously push the sewage tank (7) upward through its own elastic force. When the elastic force is greater than the magnetic force of the magnetic suction (23) and the downward gravity of the sewage tank (7), the spring (9) will assist the sewage tank (7) to reset. At this time, the overflow channel (131) and the M-shaped overflow pipe (19) are both in a closed state. Step 2: During rainy weather, the interception trough (6) still serves to intercept the initial runoff of rainwater. Since the rainwater in the early stages of rainy weather comes into contact with the ground first and is more polluted, this part of the rainwater is initially diverted through the interception component. When the sewage trough (7) moves downward, it will drive the linkage plate (12) to move downward in an arc shape through the linkage rod (10) until the other end of the linkage plate (12) closes together and is sealed by the rubber strip (20). At this time, the bottom of the guide ring (4) is in a sealed state. During the middle to late stages of rainy weather, rainwater will fall into the inner cavity of the guide ring (4) until the rainwater accumulates and submerges the sealing plate (132). The foam float (135) on the top of the sealing plate (132) will cause the sealing plate (132) to float up, causing the overflow channel (131) to open. At this time, the rainwater will pass through the overflow channel (131) and fall into the top of the barrier plate (18) through the drainage channel (146), and gather in the lower part of the inner cavity of the overflow cylinder (2), intercepting this part of the rainwater and completing the secondary diversion. Step 3: When rainwater accumulates above the opening of the M-type overflow pipe (19) at the top of the baffle plate (18), the M-type overflow pipe (19) draws the rainwater above the opening to the bottom of the overflow cylinder (2) through the siphon effect. Finally, this part of the rainwater will be discharged from the overflow cylinder (2) through the rainwater pipe (27), completing the third diversion. At the same time, the rainwater is collected by the baffle plate (18), which allows a part of the rainwater to be temporarily stored inside the overflow cylinder (2). Step 4: When heavy rain occurs and the rainwater flow in the overflow cylinder (2) is too large, in order to prevent the rainwater between the partition plate (142) and the baffle plate (18) from flowing back to the upper part of the overflow cylinder (2), the accumulation of rainwater on the top of the baffle plate (18) will cause the float (147) to gradually float upwards, and move vertically upwards on the surface of the limit rod (143) through the folded rod (145) and the slider (144) until the upper part of the float (147) blocks the drainage channel (146), so that the partition plate (142) can be closed. 2) The space between the guide ring (4) and the flow ring (4) becomes a second rainwater storage area. Since the space between the baffle plate (18) and the partition plate (142) is larger, more rainwater can be stored. The buoyancy of the float (147) is greater than the pressure of the upper rainwater on the float (147), which enables the float (147) to stably seal the drainage channel (146) until the lower rainwater is discharged through the M-shaped overflow pipe (19). Then the float (147) descends, the drainage channel (146) opens again, and the water is diverted for the last time.
