[0026] Further, the collecting cylinder 101 is fixedly connected with a blocking plate 206, one side of the blocking plate 206 is fixedly connected with a limiting block 216, the upper surface of the limiting block 216 is placed with a third filter screen 217, and the blocking plate 206 blocks the sewage under the condition of sunny or cloudy days, so as to prevent the sewage from flowing to one side of the rainwater discharge pipe 106. When the blocking plate 206 is under the condition of heavy rainfall, the liquid in the collecting cylinder 101 will quickly accumulate, and the first sewage discharge pipe 103 and the second sewage discharge pipe 104 are used. When the blocking plate 206 is under the condition of small rainfall, the mixed liquid of the collected sewage and rainwater will increase, and the blocking plate 206 is used to block the mixed liquid of the sewage, so as to prevent the mixed liquid of the sewage from flowing to one side of the rainwater discharge pipe 106. The collecting cylinder 101 is divided into two parts by the blocking plate 206, so that the two parts can collect sewage and rainwater respectively, and the sewage and rainwater can be separated at different stages, thereby improving the recycling of water resources of the equipment to a certain extent.

[0028] Further, the second filter screen 209 is fixedly connected with a blocking plate 215 on both sides, the blocking plate 215 is clampedly connected to the inner surface of the collecting cylinder 101 on one side, the upper surface of the collecting cylinder 101 is fixedly connected with a blocking arc plate 208, and the center of the third filter screen 217 is fixedly connected with a clamping block 205, wherein the third filter screen 217 can be disassembled and maintained through the clamping block 205, thereby improving the maintenance effect of the equipment.

[0029] Working principle: By using the control valve 102, the first sewage discharge pipe 103, the second sewage discharge pipe 104, the liquid inlet pipe 105 and the rainwater discharge pipe 106, the liquid inlet pipe 105 can guide the sewage or rainwater into the collecting cylinder 101, and the collecting cylinder 101 can use the first sewage discharge pipe 103 and the second sewage discharge pipe 104 to discharge the sewage in different areas to the outside for further treatment, and further, the rainwater collected by the rainwater discharge pipe 106 can be recycled and treated; By using the water-permeable roadbed 201, the permeable guide plate 202, the first inclined guide plate 203 and the second inclined guide plate 207, the rainwater can be gradually collected in the middle of the organic land 107 after penetrating into the organic land 107 through the permeable guide plate 202, and further, the rainwater or sewage can be guided into the collecting cylinder 101 through the first inclined guide plate 203 and the second inclined guide plate 207, so that the rainwater in a certain area can be quickly collected in the collecting cylinder 101; By using the first filter screen 204, the blocking plate 206, the blocking arc plate 208, the second filter screen 209, the limiting guide rail 210, the auxiliary rod 211, the inclined filter screen 212, the lifting groove 213, the L-shaped rod 214, the blocking plate 215, the limiting block 216 and the third filter screen 217, the blocking arc plate 208 can block the sewage or rainwater guided by the first inclined guide plate 203 to prevent it from flowing into the organic land 107 again, and further, when a small amount of sewage flows into the blocking plate 206, the impurities carried by the sewage can be prevented from floating in the collecting cylinder 101 by the cooperation between the first filter screen 204, the second filter screen 209, the third filter screen 217 and the inclined filter screen 212, and further, the sewage can be quickly discharged through the first sewage discharge pipe 103, so as to prevent it from being stored for a long time and accumulated therein, when a large amount of rainwater or sewage flows into the equipment, the liquid inlet pipe 105 and the blocking arc plate 208 cooperate with each other, and the liquid directly collides with the third filter screen 217 through the curved motion of the water flow, so as to impact the impurities floating on the lower surface of the third filter screen 217, so as to discharge them to the first sewage discharge pipe 103 as much as possible, and at the same time, the first filter screen 204 can filter the water flow to prevent the impurities from covering the inside of the collecting cylinder 101; The use of the baffle shunt unit 200 makes the blocking plate 206 block the sewage under sunny or cloudy conditions, prevent the sewage from flowing to the side of the rainwater discharge pipe 106, and at the same time use the control valve 102 to continuously discharge the sewage to the outside, so that the side with small area of the blocking plate 206 remains clean. When the blocking plate 206 is in the condition of small rainfall, the collected sewage and rainwater mixed liquid will increase, which is blocked by the blocking plate 206 to prevent the sewage mixed liquid from flowing to the side of the rainwater discharge pipe 106. When the inflow is greater than the discharge capacity of the first sewage discharge pipe 103, the liquid level in the collection cylinder 101 will gradually rise, and will flow to the side of the blocking plate 206, which will start the second sewage discharge pipe 104 below the rainwater discharge pipe 106, so as to avoid discharging the sewage directly from the rainwater discharge pipe 106. When the blocking plate 206 is in the condition of heavy rainfall, the liquid in the collection cylinder 101 will accumulate quickly, and the first sewage discharge pipe 103 and the second sewage discharge pipe 104 will be used to discharge the sewage and rainwater mixed liquid at the bottom of the collection cylinder 101 and the beginning of the collection at the same time, and at the same time use the scouring of rainwater to clean the inside of the collection cylinder 101 to a certain extent, so as to avoid discharging the sewage mixed liquid from the rainwater discharge pipe 106 in the subsequent process. Further, after the rainwater continues to collect, the rainwater is discharged to the outside through the rainwater discharge pipe 106 for treatment. The use of the wind stirring unit 300 in the process of discharging rainwater or sewage makes the external wind blow the spiral stress plate 302 to rotate, so as to drive the spiral blade 309 and the stirring plate 310 to rotate in the liquid to a certain extent, so as to form turbulent flow of the liquid at the bottom and the middle, and avoid a certain degree of sludge deposition. At the same time, under sunny or cloudy conditions, the water body is continuously stirred to prevent excessive oxygen deficiency of the water body and cause accumulation and odor. Example two:

[0030] Reference Figure 2 - Figure 4 The difference between the embodiment one and the embodiment two is that the outer surface of the drive shaft 303 is equidistantly distributed with a plurality of connecting rings 306, and the connecting ring 306 is inserted and connected with the drive shaft 303. The outer surface of two groups of connecting rings 306 is circumferentially distributed with a plurality of link rings 307, and the outer surface of another two groups of connecting rings 306 is circumferentially distributed with stirring plates 310, and the stirring plates 310 are internally provided with special-shaped turbulence grooves. The stirring plates 310 and the special-shaped turbulence grooves internally provided therein can stir a small amount of sewage in the interior to a certain extent, so as to prevent the sewage from being stationary and affecting the surrounding environment.

[0031] Further, when the spiral stress plate 302 is driven by the outside, it synchronously drives the spiral blade 309 and the stirring plate 310 to rotate in the liquid to a certain extent, so that the liquid at the bottom and the middle forms a turbulent flow, avoids a certain degree of sludge precipitation, and at the same time, under sunny or cloudy conditions, the water body is continuously stirred to prevent the water body from being excessively deoxygenated to cause accumulation and odor. The spiral stress plate 302 and the driving shaft 303 connected thereto rotate as a whole under the influence of the outside air flow, so that the liquid in the collecting cylinder 101 is kept in a flowing state to a certain extent.

[0032] Further, the rotating rod 308 is rotatably connected in the adapter ring 307, the outer surface of the rotating rod 308 is fixedly connected with the spiral blade 309, and the side of the rotating rod 308 away from the driving shaft 303 is not in contact with the blocking plate 206. By the rotatable spiral blade 309, the device can continuously stir the internal rainwater in a windy and rainy environment, thereby preventing a large amount of impurities from continuously accumulating on one side of the first filter plate to a certain extent, thereby improving the filtering effect of the device.

[0033] Working principle: The core purpose of the municipal water resource recycling device of the sponge city is to realize automatic and efficient separation and quality storage of initial rainwater or domestic sewage and later clean rainwater through a series of ingenious mechanical structure design, so as to improve the water quality of recycled rainwater from the source, reduce the subsequent treatment cost and energy consumption. The working principle is based on gravity flow, liquid level difference, mechanical filtration and wind energy driving. The whole process does not need external intelligent control or power intervention. The specific description is as follows: Firstly, the initial rainwater or domestic sewage on the municipal road surface enters the collecting cylinder 101 through the liquid inlet pipe 105, at the same time, the rainwater infiltrated from the surrounding organic land 107 area is guided to the center under the guidance of the infiltration guide plate 202, and is also introduced into the collecting cylinder 101 under the further guidance of the first inclined guide plate 203 and the second inclined guide plate 207. The function of the blocking arc plate 208 is to prevent the liquid introduced by the inclined guide plate from splashing or flowing back to the organic land 107, so as to ensure that all the liquid enters the treatment process; Secondly, after the liquid enters the collecting cylinder 101, it first hits the inclined filter screen 212, which can disperse the water flow impact force and complete the preliminary screening. The liquid then passes through the first filter screen 204 for filtration, so that the first filter screen 204 can effectively intercept the larger solid particles, leaves, plastics and other suspended impurities carried in the water body, preventing them from entering the core area of the device. The blocking plate 215 ensures the sealing of the second filter screen 209 and the inner wall of the collecting cylinder 101, preventing the unfiltered liquid from flowing through the short circuit. Most of the intercepted impurities slide down along the inclined filter screen 212 under the action of gravity, so that they are mixed with sewage again and discharged. Thirdly, the baffle plate 206 permanently separates the inner cavity of the collecting cylinder 101 into two functionally different chambers: a sewage chamber and a clean water chamber. The sewage chamber is the area where the multiple filter screens are located, and the clean water chamber is the area on the same side as the rainwater discharge pipe 106. This is the key structure for separating rainwater and sewage, and it dynamically switches the working mode according to the amount of liquid: Sunny or overcast days: At this time, the amount of water entering the device is small, mainly sewage. The liquid is effectively blocked in the sewage chamber by the baffle plate 206. The operator can open the control valve 102 to allow the sewage to be discharged through the first sewage discharge pipe 103 and into the municipal sewage pipe network. This process ensures that the sewage does not overflow into the clean water chamber, ensuring the cleanliness of the clean water chamber and preparing it to receive later clean rainwater. The third filter screen 217 is placed on the limiting block 216 by the clamping block 205 to prevent impurities in the sewage from rising with the water level and overflowing into the clean water chamber. It can also be easily lifted for maintenance and cleaning when needed. Light rain to moderate rain period: As the rain continues, the amount of water increases, and the liquid level in the sewage chamber rises. When the liquid level rises above the top of the baffle plate 206, the mixed liquid begins to overflow into the clean water chamber. However, because most of the initial rainwater with high pollution concentration has been intercepted and discharged earlier, the water quality of the overflowing water has improved. The device uses the second sewage discharge pipe 104 to preferentially discharge this part of the mixed liquid, continuing to protect the clean water chamber from serious pollution and ensuring that only rainwater with up-to-standard water quality is discharged from the rainwater discharge pipe 106. Heavy rain or storm period: At this time, the amount of water entering is much larger than the discharge capacity of the sewage discharge pipe. The liquid level in the collecting cylinder 101 rises rapidly and comprehensively. The device enters "flushing mode". A large amount of rainwater forms a strong water flow, which flushes the inside of the collecting cylinder 101. On the one hand, the water flow impacts the third filter screen 217, which can remove impurities attached to its lower surface. On the other hand, the high-speed water flow drives the impurities deposited in the sewage chamber to mix with the liquid and be quickly discharged through the first and second sewage discharge pipes 103 and 104, achieving self-cleaning effect of the device. After a period of rain, i.e. after the initial flushing effect, it is confirmed that the inflow is relatively clean rainwater. The control valve 102 on the sewage discharge pipe can be closed to allow clean rainwater to be directly discharged through the rainwater discharge pipe 106 for storage and used for urban greening, landscape water supplementing, and other recycling purposes. Then, the wind agitation unit 300 at the top of the device is an auxiliary protection device for maintaining water quality. Natural wind blows the spiral stress plate 302, causing it to rotate and process. The rotational motion is transmitted to the water in the collecting cylinder 101 through the drive shaft 303. The agitation plate 310 on the drive shaft 303 rotates, and the special-shaped turbulence groove inside it can efficiently break the water flow pattern and generate turbulence. At the same time, the spiral leaf 309 connected by the connecting ring 307 and the rotating rod 308 also rotates in the water, The device is in working state: one is in the process of rainwater discharge, stirring water to prevent sludge deposition in the pool; two is in the dry or cloudy days, sewage stored in the warehouse may be in a state of stagnation, the continuous mechanical stirring can increase the contact between water and air, effectively prevent water from anaerobic spoilage, avoid secondary pollution to the surrounding environment, the whole process is driven by wind energy, energy saving and environmental protection; Finally, the filter system of the device is designed with a convenient maintenance structure, the first filter screen 204 is connected with the limiting guide rail 210 through the auxiliary rod 211 and the L-shaped rod 214, and can be lifted as a whole along the lifting groove 213, so that the impurities trapped on the first filter screen 204 and the second filter screen 209 can be conveniently cleaned, and the third filter screen 217 can also be disassembled and cleaned through the lifting clamping block 205, which greatly reduces the long-term maintenance difficulty and cost of the device.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting.
