[0002] Urban rainwater drainage systems can effectively reduce urban waterlogging. Through proper drainage design, they can quickly remove accumulated water during heavy rainfall, preventing road flooding and traffic congestion, and minimizing property damage and casualties caused by flooding. Furthermore, rainwater collection and utilization can conserve water resources and promote sustainable urban development.

[0003] Publication number CN115306015B discloses a sponge city drainage structure with a water purification function. The problem raised in its background technology is that it is inconvenient for personnel to disassemble the internal components of the drain outlet, and the internal components are prone to wear and deformation after long-term use, resulting in a reduced filtering effect on impurities in rainwater and a shortened service life of the entire equipment.

[0004] Based on the existing technology, the following problems exist: When using the existing urban rainwater inlets, it is not convenient to automatically divert rainwater according to the amount of rainwater, which makes it inconvenient to collect rainwater. At the same time, it causes excessive rainwater to accumulate in the rainwater inlet, affecting the discharge of rainwater. In addition, fallen leaves are easily accumulated on the water inlet grate of the rainwater inlet along with the rainwater, affecting the efficiency of rainwater entering the rainwater inlet and affecting the drainage use. Referring to the above application documents, it only installs the water inlet grate through an elastic mechanism, but the mechanism for installing the water inlet grate is relatively complicated and not convenient for actual use. There are certain shortcomings. In order to solve the above problems, an urban rainwater comprehensive drainage structure and method are proposed. Summary of the Invention

The bottom of the limit rod extends to the bottom of the limit seat and is fixedly connected to the inner concave part of the arc tube. The side wall diameter of the limit block is larger than the side wall diameter of the limit rod, so that the limit block cooperates with the inner wall stop of the limit groove, thereby limiting the limit rod from being separated from the limit groove.

[0016] The present invention provides a comprehensive urban rainwater drainage structure and method. Compared with the existing technology, it has the following advantages: 1. The present invention uses a diversion mechanism to directly discharge rainwater into the sewer when there is less rain. When there is more rain, the rainwater enters the U-shaped tube along the top of the first vertical tube, and part of the rainwater is filtered through the filter cartridge and then transported to the external pipe, thereby sharing the amount of rainwater in the wellbore. When there is more rain and the water quality is better, the rainwater can be collected, thereby facilitating the recycling of water resources. The diversion mechanism cooperates with the cleaning mechanism to clean the fallen leaves on the top of the water inlet mechanism to avoid affecting the use of drainage.

[0017] 2. The present invention provides a U-shaped tube, so that after rainwater enters the U-shaped tube, part of the rainwater can flow outward along the filter cartridge, thereby transporting the rainwater to a designated pipeline for subsequent recycling of the rainwater. Part of the rainwater that enters the U-shaped tube can be discharged into the sewer along the top of the second vertical tube, which facilitates the transport of rainwater to the designated pipeline and the sharing of the amount of rainwater in the wellbore, thereby reducing the probability of excessive rainwater accumulation in the wellbore and the probability of rainwater not being able to be discharged in time, and facilitating actual urban drainage use.

[0018] 3. The present invention arranges the filter cartridge on the side wall of the second vertical pipe. When rainwater flows upward along the second vertical pipe, it can wash away the impurities filtered by the filter cartridge and discharge it into the sewer along the top of the second vertical pipe, thereby facilitating long-term filtration by the filter cartridge and improving the water quality of rainwater reuse.

[0019] 4. The present invention cooperates with the diversion mechanism and the cleaning mechanism to lift the fallen leaves accumulated on the top of the water inlet grate, and washes the fallen leaves away from the water inlet grate under the flow of rainwater, thereby avoiding a large number of fallen leaves from accumulating on the top of the water inlet grate to avoid affecting the entry of rainwater into the wellbore, thereby avoiding affecting the discharge of rainwater. While lifting the fallen leaves, rainwater can enter the wellbore along the second water inlet groove, etc., which is convenient for cleaning the fallen leaves without affecting the entry of rainwater into the wellbore.

[0020] 5. The present invention provides plug rods at the end corners of the water inlet grate, and makes the plug rods fit with the inner walls of the first slots respectively, so that the water inlet grate cannot be deflected. Even if the water inlet grate can only move vertically, the stability of the water inlet grate installation is improved, and the installation method is simpler than that of traditional water inlet grates.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A comprehensive urban rainwater drainage structure includes a well 1, and also includes a water inlet mechanism 2 and a cleaning mechanism 4 arranged at the upper end of the inner wall of the well 1, and the cleaning mechanism 4 is located at the bottom of the water inlet mechanism 2, and the bottom inner wall of the well 1 is provided with a diversion mechanism 3 extending to the outside of the well 1.

[0025] Lug plates 11 are fixed on both sides of the top of the shaft 1 to install the shaft 1 into the pre-buried groove; The bottom inner wall of the wellbore 1 is provided with water guide holes 12 arranged at intervals.

[0026] In specific implementation, the well 1 is installed in the pre-buried grooves on both sides of the road through the ear plates 11, so that when it rains, rainwater enters the well 1 along the water inlet mechanism 2 and is discharged into the sewer along the water guide holes 12 on the inner wall of the bottom of the well 1, thereby draining the rainwater to meet the needs of urban drainage; When installing the well shaft, a space for the U-shaped pipe 31 to be raised and lowered must be left between the bottom of the well shaft 1 and the sewer for practical use.

[0027] See also Figure 3 、 Figure 4 、 Figure 10 and Figure 12 , the diversion mechanism 3 includes: A U-shaped tube 31 is arranged on the bottom inner wall of the shaft 1 in a lifting manner. A limit assembly 32 is provided at the bottom of the shaft 1 for elastically supporting the U-shaped tube 31. The U-shaped tube 31 includes a first vertical tube 311, an arc-shaped tube 312, and a second vertical tube 313. The first vertical tube 311 and the second vertical tube 313 are respectively fixedly connected to the ends of the arc-shaped tube 312. The lifting assembly 33 is provided on the inner wall of one end of the first vertical tube 311 located in the wellbore 1, so as to drive the cleaning mechanism 4 to rise and fall when the U-shaped tube 31 rises and falls, thereby cleaning the water inlet mechanism 2; The filter cartridge 36 is fixed to the outer wall of the second vertical tube 313 and communicates with the inner wall of the second vertical tube 313 . The top of the second vertical tube 313 is lower than the top of the first vertical tube 311 .

[0028] In specific implementation, when there is less rain, the rainwater enters the wellbore 1 along the water inlet mechanism 2 and the cleaning mechanism 4, and is discharged into the sewer along the water guide hole 12 on the inner wall of the bottom of the wellbore 1, thereby draining the rainwater; When there is a lot of rain, the difference between the discharge volume and the intake volume of the wellbore 1 is large, resulting in excessive accumulation of rainwater in the wellbore 1. At this time, the liquid level of rainwater in the wellbore 1 continues to increase, causing the rainwater to enter the U-shaped tube 31 along the top of the first vertical tube 311 and flow along the arc tube 312 and the second vertical tube 313. After the filter cartridge 36 is connected to the external pipeline, part of the rainwater is filtered by the filter cartridge 36 and transported to the external pipeline, thereby sharing the amount of rainwater in the wellbore 1.

[0029] When there is less rain, the water quality is poor due to the large amount of impurities such as dust mixed in the rain. At this time, it is directly discharged to the sewer through the well 1 for actual drainage use. When there is more rain, the dilution effect on the dust is better, and the water quality is better than when there is less rain. At this time, part of the rainwater is transported to the designated pipeline through the diversion mechanism 3, which is convenient for collecting rainwater and facilitating the recycling of water resources.

[0030] Since the U-shaped tube 31 is at the same atmospheric pressure, under the action of gravity, the liquid level heights on both sides of the U-shaped tube 31 are the same, and since the top of the second vertical tube 313 is lower than the top of the first vertical tube 311, after the rainwater enters the U-shaped tube 31, part of the rainwater can flow outward along the filter cartridge 36, thereby transporting the rainwater to the designated pipeline for collection, thereby facilitating the subsequent recycling of the rainwater. Part of the rainwater entering the U-shaped tube 31 can be discharged into the sewer along the top of the second vertical tube 313, which is convenient for transporting the rainwater to the designated pipeline while facilitating the sharing of the amount of rainwater in the wellbore 1, thereby reducing the probability of excessive rainwater accumulation in the wellbore 1, reducing the probability of rainwater not being able to be discharged in time, and facilitating actual urban drainage use.

[0031] And because the filter cartridge 36 is arranged on the side wall of the second vertical pipe 313, when rainwater flows upward along the second vertical pipe 313, it can wash away the impurities filtered by the filter cartridge 36 and discharge it into the sewer along the top of the second vertical pipe 313, thereby facilitating long-term filtration by the filter cartridge 36, thereby improving the water quality of rainwater reuse.

[0032] See also Figure 12 、 Figure 13 and Figure 14 , the lifting assembly 33 includes: The limiting member 336 is fixedly mounted on the inner wall of the shaft 1. The top of the limiting member 336 is sleeved with a lifting rod 331. The lower end of the side wall of the lifting rod 331 is sleeved on the inner wall of one end of the first vertical tube 311 located in the shaft 1. The top of the lifting rod 331 is fixedly connected to the bottom of the partition 41. The side wall of the lifting rod 331 and the inner wall of the first vertical tube 311 are respectively fixed with a first tooth plate 334 and a second tooth plate 333. The gear 332 is rotatably mounted on the bottom of the stopper 336, and the side walls of the gear 332 are respectively engaged with the first tooth plate 334 and the second tooth plate 333 to transmit the connection between the U-shaped tube 31 and the lifting rod 331, thereby driving the partition 41 to move up and down. When the partition 41 is driven to move to the top dead center, a gap is left between the top of the partition 41 and the bottom of the water inlet grate 21. The first slide groove 335 is opened on the inner side wall of the first vertical tube 311 and is arranged opposite to the second gear plate 333. A first slider is placed inside the first slide groove 335. The first slider is fixedly connected to the lifting rod 331 to limit the lifting rod 331.

[0033] See also Figure 15 , the limiting component 32 includes: The limit seat 321 is fixed to the bottom of the wellbore 1, and a limit groove 322 is provided at the bottom of the limit seat 321. The inner wall of the limit groove 322 is provided with a limit block 323 and a limit rod 324, and the limit block 323 and the limit rod 324 are fixedly connected on the side close to each other. The bottom of the limit rod 324 extends to the bottom of the limit seat 321 and is fixedly connected to the inner recess of the arc tube 312. The side wall diameter of the limit block 323 is larger than the side wall diameter of the limit rod 324, so that the limit block 323 cooperates with the inner wall stop of the limit groove 322, thereby limiting the limit rod 324 from disengaging from the limit groove 322. The limit rod 324 is located on one end side wall of the limit groove 322 and is located at the bottom of the limit block 323 and is provided with a spring.

[0034] In a specific implementation, the limit block 323 is elastically supported by the spring, and the U-shaped tube 31 is elastically supported by the limit rod 324. When the amount of rainwater in the wellbore 1 is small, the liquid level of rainwater in the wellbore 1 is below the top of the first vertical tube 311, that is, rainwater does not enter the U-shaped tube 31. At this time, under the action of the spring, the U-shaped tube 31 is located at the top dead center. At this time, under the action of the lifting assembly 33, the partition 41 is located at the bottom dead center, that is, the stop plate 44 is located in the first water inlet groove 22; When the liquid level of rainwater in the wellbore 1 is at the top of the first vertical tube 311, the rainwater enters the U-shaped tube 31. As the liquid level continues to rise, more rainwater enters the U-shaped tube 31. At this time, the weight of the U-shaped tube 31 increases to overcome the elasticity of the spring and move the U-shaped tube 31 downward, thereby driving the gear 332 to rotate through the first tooth plate 334, and driving the second tooth plate 333 and the lifting rod 331 to move upward through the gear 332, so as to drive the partition 41 to move upward, so that the cleaning mechanism 4 cleans the water inlet mechanism 2 to avoid excessive accumulation of fallen leaves at the water inlet grate 21, which affects the use of drainage.

[0035] The first sliding groove 335 and the first sliding block are used to limit the lifting rod 331, and the limiting member 336 is used to limit the lifting rod 331 to improve its lifting stability. The limiting member 336 is used to facilitate the installation of the gear 332 to facilitate transmission use.

[0036] See also Figure 10 and Figure 11 , the diversion mechanism 3 also includes: The second chute 34 is formed in a circular array on the outer wall of the first vertical tube 311. The bottom inner wall of the wellbore 1 is provided with a mounting hole for sleeve-mounting the first vertical tube 311. The inner wall of the mounting hole is fixed with a second slider arranged in a circular array, and the second slider is placed in the second chute 34. A third chute 35 is provided on the outer wall of the shaft 1. A third slider is fixed to the outer wall of the second vertical tube 313. The third slider is placed in the third chute 35. In specific implementation, the first vertical tube 311 and the second vertical tube 313 of the U-shaped tube 31 are limited by the second slide groove 34 and the third slide groove 35, thereby improving the stability of the vertical movement of the U-shaped tube 31 and improving the stability of the elastic support of the U-shaped tube 31 by the limiting component 32.

[0037] Example 2: Please refer to Figure 5 、 Figure 6 、 Figure 8 and Figure 9 The difference between this embodiment and the first embodiment is that the water inlet mechanism 2 includes: The water inlet grate 21 is sleeved on the inner wall of the wellbore 1. The top of the water inlet grate 21 is provided with first water inlet grooves 22 arranged at intervals so that rainwater can enter the wellbore 1 along the first water inlet grooves 22. The cleaning mechanism 4 includes: The partition 41 has a top fixed with spaced-apart abutment plates 44 extending into the first water inlet groove 22 , and a top of the partition 41 and located between the abutment plates 44 has spaced-apart second water inlet grooves 42 .

[0038] The water inlet mechanism 2 also includes: The second T-shaped groove 26 is formed on both sides of the top of the wellbore 1 and is located between the first T-shaped groove 46; The second T-shaped blocks 23 are fixedly disposed on both sides of the water inlet grate 21 and fit in with the inner wall of the second T-shaped slot 26 . A groove is formed on the top of the second T-shaped block 23 .

[0039] The water inlet mechanism 2 also includes: A first slot 28 is provided at the top of the shaft 1 and near an end corner of the shaft 1. An inner groove 29 is provided at the top of the shaft 1 and outside the first slot 28. A second slot 27 is provided at the top of the shaft 1 and communicates with the inner groove 29 and the inner wall of the shaft 1. The insert block 24 is fixed on the side wall of the water inlet grate 21 and close to the end corner of the water inlet grate 21. The insert block 24 is fixed with an insert rod 25 on the side away from the water inlet grate 21. The side walls of the insert block 24 and the insert rod 25 are respectively fitted with the inner walls of the second slot 27 and the first slot 28 to limit the water inlet grate 21.

[0040] In a specific implementation, by providing the insertion rods 25 at the end corners of the water inlet grate 21, and making the insertion rods 25 respectively fit with the inner walls of the first slots 28, the water inlet grate 21 cannot be deflected. Even if the water inlet grate 21 can only move vertically, the stability of the installation of the water inlet grate 21 is improved, and the installation method of the water inlet grate 21 is simpler than that of the traditional water inlet grate 21. The water inlet grate 21 is installed by the auxiliary insertion rod 25 and the first slot 28 through the second T-shaped slot 26 and the second T-shaped block 23, and it is convenient for the staff to hold the water inlet grate 21 through the pull groove, thereby facilitating actual operation; The water inlet grate 21 and the insertion rod 25 are connected by the plug block 24, and the plug block 24 is placed through the second slot 27, so that after the water inlet grate 21 is installed, the top of the water inlet grate 21 is slightly lower than the top of the well shaft 1, or is level with the top of the well shaft 1, so as to facilitate actual installation and use. The actual installation and use are facilitated by setting the inner groove 29.

[0041] The dimension of the abutment plate 44 along the length direction of the shaft 1 is smaller than the inner wall diameter of the first water inlet groove 22 along the length direction of the shaft 1, so that rainwater can flow downward along the gap between the abutment plate 44 and the first water inlet groove 22, thereby allowing rainwater to enter the shaft 1 along the second water inlet groove 42; When the plate 44 is at the bottom dead center, the top of the plate 44 is located in the first water inlet groove 22. When the plate 44 is at the top dead center, the top of the plate 44 is located above the top of the water inlet grate 21. The plate 44 is made of elastic rubber material. Water guide grooves 43 are formed on both sides of the support plate 44 .

[0042] See also Figure 4 、 Figure 5 、 Figure 7 and Figure 8 , the cleaning mechanism 4 also includes: The first T-shaped grooves 46 are formed on both sides of the top of the wellbore 1 and communicate with the inner wall of the wellbore 1. The first T-shaped grooves 46 are symmetrically arranged around the center of the wellbore 1. The first T-shaped blocks 45 are fixedly arranged on both sides of the partition 41 at intervals and fit in the inner wall of the first T-shaped slot 46. The inner wall of the first T-shaped slot 46 has a height reserved for the vertical movement of the first T-shaped blocks 45. The rubber stopper 47 is sleeved on the inner wall of the first T-shaped groove 46 and is located on the top of the first T-shaped block 45 .

[0043] During specific implementation, when the U-shaped tube 31 drives the lifting rod 331 to move upward, the lifting rod 331 drives the partition 41 to move upward, thereby driving the support plate 44 to move upward along the first water inlet groove 22 to lift the fallen leaves accumulated on the top of the water inlet grate 21. At this time, under the flow of rainwater, the fallen leaves are washed away from the water inlet grate 21, thereby avoiding a large number of fallen leaves from accumulating on the top of the water inlet grate 21, so as to avoid affecting the rainwater from entering the wellbore 1, thereby avoiding affecting the discharge of rainwater. While lifting the fallen leaves, the rainwater can flow downward along the gap between the support plate 44 and the first water inlet groove 22, and enter the second water inlet groove 42 along the gap between the water inlet grate 21 and the partition 41, so as to enter the wellbore 1 along the second water inlet groove 42, which is convenient for cleaning the fallen leaves without affecting the rainwater from entering the wellbore 1.

[0044] When the U-shaped tube 31 moves downward to the lowest point, under the action of the lifting assembly 33, the lifting rod 331 moves to the highest point. At this time, the partition 41 and the support plate 44 are located at the upper dead center, which is convenient for cleaning fallen leaves. When the U-shaped tube 31 is reset, the partition 41 and the support plate 44 move downward and reset to the lower dead center. At this time, the support plate 44 is located at the lower end of the inner wall of the first water inlet groove 22, which is convenient for the next support plate 44 to move upward along the inner wall of the first water inlet groove 22.

[0045] By setting the water guide groove 43, the gap between the side wall of the support plate 44 and the first water inlet groove is increased to facilitate the flow of rainwater without affecting the area of ​​the top of the support plate 44, thereby not affecting the lifting of fallen leaves, thereby avoiding affecting the use of cleaning fallen leaves.

[0046] The first T-shaped slot 46 and the first T-shaped block 45 facilitate the lifting and lowering limit of the partition 41, thereby improving the lifting stability. The first T-shaped slot 46 is sealed by the rubber plug 47, which is convenient for practical use.

[0047] An embodiment of the present invention further provides a method for using an urban rainwater integrated drainage structure, using an urban rainwater integrated drainage structure, the method comprising the following steps: S1: Install the shaft 1 at a designated location, usually on both sides of the road, to facilitate access to the shaft 1, thereby transporting rainwater to meet the needs of urban rainwater discharge. When it rains, rainwater enters the shaft 1 along the water inlet mechanism 2 and the cleaning mechanism 4, and is discharged into the sewer along the shaft 1; S2: When there is a lot of rainwater, part of the rainwater is transported to the designated pipeline through the diversion mechanism 3 to share the drainage volume of the wellbore 1; S3: When a large amount of rainwater enters the diversion mechanism 3, the weight of the rainwater overcomes the elastic support force of the limiting component 32 on the U-shaped tube 31, so that the cleaning mechanism 4 is driven close to the water inlet mechanism 2 through the lifting component 33, thereby lifting the fallen leaves on the top of the water inlet grate 21, and washing away the fallen leaves with the help of rainwater.
