Among the existing municipal drainage structures, the underground drainage structures are often utilized, namely, through the arrangement of different pipelines, the underground drainage structures are communicated with different water inlets, so that the classified drainage effect is achieved, among drainage systems communicated with the ground, water is often directly discharged into the municipal wastewater pipelines, but in the rainy season in the south, a large amount of rainwater can be generated, if the rainwater is directly connected into the drainage pipelines through the ground without treatment, the rainwater is directly mixed with resident excreta in the municipal wastewater pipelines, kitchen water and the like, irrigation water is required to be formed through a plurality of processes, fresh water which can be drunk by people cannot be utilized, and if pipelines for recovering the rainwater are independently built, the waste is relatively high in the rainless season, the construction amount is increased, but in the rainy season, if a rainwater recovery system is not built, a large amount of rainwater also can cause a large burden on the original drainage, so that drainage is difficult and recovery difficulty becomes a large problem of municipal drainage, and the cost of maintaining the drainage structures is huge each year, in order to solve the technical problems as follows:

referring to fig. 1 to 8, a municipal construction rapid drainage system electrically connected with a rain and snow sensor installed at the top of a building, comprising: the movable cover 1 is clamped on the road surface; an upper sealed cavity 2 connected below the movable cover 1; the lower through cavity 3 is integrally formed below the upper sealing cavity 2, and the lower through cavity 3 is communicated with the rainwater recovery pipe A; the bottom sealing structure 4 is movably connected to the bottom of the lower through cavity 3, and the bottom sealing structure 4 is communicated with the wastewater recovery pipe B; the movable cover 1 and the bottom sealing structure 4 are electrically connected with the rain and snow sensor; the reflow detection structure 6 is welded at the middle section position inside the upper sealing cavity 2, and the reflow detection structure 6 is electrically connected with the bottom sealing structure 4; a plurality of filter drawers 7 which are connected in a sliding way in the lower through cavity 3.

In this embodiment, there are three drainage modes, namely, a normal drainage mode, a rainwater recovery mode, and a storm water circulation mode, and the specific drainage modes are as follows:

in the normal drainage mode, the rain and snow sensor does not sense that the external environment is in a raining state, so that the bottom sealing structure 4 is in an opened state, the waste water recovery pipe B is directly communicated with the lower through cavity 3, at the moment, the external waste water is small amount of waste water such as water flowing down in garden irrigation and caused in working production of citizens, the waste water has no recovery meaning, the small amount of waste water flows in through the movable cover 1, then flows into the upper sealed cavity 2 and the lower through cavity 3 respectively, and directly enters municipal pipelines through the waste water recovery pipe B after being filtered by the filtering drawer 7, so that the waste water is not required to be recovered, and normal drainage can be carried out.

In the rainwater recovery mode, the rain and snow sensor senses that the outside is in a raining state, signals can be sent to the bottom sealing structure 4, the bottom sealing structure 4 starts to be folded, a pipeline between the waste water recovery pipe B and the lower transparent cavity 3 is closed, at the moment, a large amount of inflow rainwater can be blocked by the bottom sealing structure 4 after passing through the movable cover 1, the upper sealing cavity 2, the lower transparent cavity 3 and the filter drawer 7, flows out in the direction of the rainwater recovery pipe A, a large amount of rainwater flows out through the special rainwater recovery pipe A and is collected to a recovery plant specially treating the rainwater, and industrial water or other fresh water usage can be formed after simpler procedures.

In the storm circulation mode, on the premise of recovering based on the rainwater recovery mode, a large amount of rainwater flows out in the direction of the rainwater recovery pipe A, but because the rain potential is large, the rainwater recovery pipe A cannot discharge a large amount of inflow rainwater, the accumulated rainwater can rise upwards, the liquid level is continuously raised, when the water level rises to the middle section position of the upper sealing cavity 2, the phenomenon of outward pouring of the rainwater at the moment exists, so when the water level rises to the position of the backflow detection structure 6, the backflow detection structure 6 senses the water level rising, sends a starting signal to the bottom sealing structure 4 to enable the bottom sealing structure 4 to be opened again, a large amount of rainwater leaks in the direction of the wastewater recovery pipe B, the problem of rainwater recovery is not considered any more, and the setting of the rain and snow sensor is reset until the end of the rain.

Through the automatic switching of the three modes, the waste water drainage effect under the normal state can be realized, the rain is recovered in rainy seasons under heavy rain, and the waste water is quickly drained under the condition of heavy rain, so that the problem of recovering the rain is solved, the phenomenon of backflow of water flow in the heavy rain stage is not needed, and the condition of water accumulation on the ground is relieved.

In this embodiment, the upper sealed cavity 2 is a square or circular cylindrical structure with a sealed periphery, and the lower transparent cavity 3 is a square or circular cylindrical structure with meshes on the periphery, so when water is blocked by the bottom sealing structure 4, the water can flow in the direction of the rainwater recovery pipe a through the meshes of the lower transparent cavity 3, and although a plurality of filter drawers 7 are arranged in the horizontal direction of the rainwater recovery pipe a, the purpose of the filter drawers 7 is to filter solids, and the normal circulation of the water to the wastewater recovery pipe B is not affected.

In this embodiment, the rain and snow sensor is a common rain and snow sensor in the prior art, and the principle of the rain and snow sensor is that a grid electrode is adopted, and the conductivity of water is utilized, so that when rainwater falls onto an induction section, the electrode is short-circuited, and the device can monitor the rain, and is often arranged on municipal buildings, such as a telegraph pole or a resident house along a street.

The rain and snow sensor is in wireless communication connection with the movable cover 1 and the bottom sealing structure 4, and the reflux detection structure 6 and the bottom sealing structure 4 can be in wired connection or wireless communication connection.

In fact, in order to facilitate the maintenance, each movable cover 1 is in a detachable state, and the movable cover 1 is specifically configured in such a manner that the movable cover 1 includes an outer mounting cover 11, a mounting member 14 annularly disposed on the outer peripheral surface of the outer mounting cover 11, an inner mounting cover 12 movably connected to the inner side of the outer mounting cover 11, and the inner mounting cover 12 and the outer mounting cover 11 are movably connected through a rotating member 13, and the rotating member 13 is electrically connected to the rain and snow sensor, in this embodiment, the outer mounting cover 11 and the inner mounting cover 12 may have a circular structure, and in other embodiments, may have other shapes, for example, may have a triangular, square, regular pentagonal structure, etc., but in order to ensure the degree of fit, the outer mounting cover 11 and the inner mounting cover 12 need to have the same shape but different structures.

Regarding the movable cover 1, firstly, the inner mounting cover 12 is not a constant planar structure, in order to limit sundries flowing into the drainage system, the inner mounting cover 12 needs to be perforated, however, in the process of draining a large amount of water in a rainy day, the design of draining a large amount of water through the small holes on the inner mounting cover 12 is certainly insufficient, so the inner mounting cover 12 comprises two semicircular cover plates 121, a riveted matching part 123 is connected between the adjacent cover plates 121, a plurality of uniform water draining holes 122 are formed on the cover plates 121, one end of the cover plates 121 far away from the matching part 123 is hinged with the rotating piece 13, the inner mounting cover 12 is divided into two cover plates 121 which can be opened and closed at any time, in order to open and close the water draining system in the rainy day, the matching part 123 is designed, the matching part 123 is a groove structure, and in the corresponding other cover plate 121, the matching part 123 is a clamping block, so when the two cover plates 121 are closed, a riveted structure is formed between the two matching parts, and in order to prevent the sundries from flowing through the water draining holes 122 in the process.

Next, in a rainy day, the rain and snow sensor sends a signal to the rotating member 13, and the specific structure is set as follows: the rotating member 13 includes a first rotating motor 132, and a first rotating cylinder 133 fixed to an output shaft of the first rotating motor 132, the first rotating cylinder 133 is fixedly connected to the cover plate 121, the first rotating motor 132 is electrically connected to the rain and snow sensor, when the rain arrives, the rain and snow sensor transmits a signal to a control chip of the first rotating motor 132, the first rotating motor 132 is controlled to rotate by 10 ° to enable the first rotating motor 132 to drive the cover plate 121 to rotate, the rotating speed of the cover plate 121 with a clamping block is slightly faster than that of the cover plate 121 with a clamping block, when the cover plate is reset, the reset speed of the cover plate 121 with the clamping block is faster than that of the cover plate 121 with the clamping block, if the rotating angle is smaller than 10 °, the opening gap is smaller, the water flowing in unit time is difficult to be conducted away, and if the rotating angle is larger than 10 °, the branches and the like with larger volumes can enter the drainage system through the opening gap, so that the effect on other structures in the system is larger.

Finally, since maintenance is required to be performed inside the drainage system occasionally, the outer mounting cover 11 needs to be set to be in a movable state, in order to reduce the difficulty of mounting, the mounting member 14 comprises a mounting groove 141 recessed toward the inner side of the cover plate 121, a spring 142 pinned in the mounting groove 141, a spring plate 143 locked and fixed with the other end of the spring 142, and a pull tab 144 fixed on the spring plate 143, when mounting, the spring plate 143 is compressed by pressing the spring plate 143, so that the spring plate 143 can be retracted into the mounting groove 141 to be matched with a concrete groove structure prefabricated in the pavement structure, and when dismounting is required, the spring plate 143 is pressed into and ejected again by pressing the pull tab 144, thereby realizing quick dismounting.

In the three modes, the state of the bottom sealing structure 4 is the most important in practice, and since the bottom sealing structure 4 needs to bear a large amount of rainwater and then enables the rainwater to flow in the direction of the rainwater recovery pipe a, the bottom sealing structure 4 needs to have certain strength, the bottom sealing structure is specifically configured in that the bottom sealing structure 4 comprises a baffle plate 41 sealing the bottom of the lower through cavity 3, a swinging structure 42 fixed on one side of the baffle plate 41 and hinged with the lower through cavity 3, a fixing piece 43 connected below the swinging structure 42, and a booster piece 44 hinged on one side of the fixing piece 43 and hinged with the lower part of the baffle plate 41, wherein the swinging structure 42 plays a role of rotating the baffle plate 41, and the booster piece 44 plays a role of rotating and driving the baffle plate 41 and also plays a role of supporting, and can bear the baffle plate 41 so that the water cannot leak into the wastewater recovery pipe B under the action of the heavy rainwater.

In order to achieve the rotation effect of the swing structure 42 and the supporting rotation effect of the booster 44, first, the swing structure 42 includes a second rotary drum 421 fixed to the baffle plate 41, a second rotary motor 422 having an output shaft connected to the second rotary drum 421, the second rotary motor 422 being electrically connected to the rain and snow sensor and the backflow detecting structure 6, respectively, when the second rotary motor 422 is driven by a signal of the rain and snow sensor, the second rotary motor 422 rotates counterclockwise, driving the baffle plate 41 to seal the lower through cavity 3 and the waste water recovery pipe B for mass recovery of rainwater, and when the second rotary motor 422 is driven by a signal of the backflow detecting structure 6, the second rotary motor 422 rotates clockwise, driving the baffle plate 41 to rotate downward, opening a passage between the lower through cavity 3 and the waste water recovery pipe B, the power assisting component 44 comprises a first connecting seat 441 locked with the baffle 41 and a second connecting seat 443 locked with the fixing component 43, and pushing components 442 hinged with the first connecting seat 441 and the second connecting seat 443 respectively, in this embodiment, the pushing components 442 are push rod motors, when the push rod motors are driven by signals of the rain and snow sensors, the push rod motors push out the baffle 41, when the push rod motors are driven by signals of the rain and snow sensors, the push rod motors retract the baffle 41, and the baffle 41 and the fixing component 43 are in hinged states, so that the baffle 41 can be driven to move in an arc shape in the pushing and retracting process, and in the pushing out process of the push rod 442, a supporting arm can be formed due to the supporting effect of the push rod motors, so that the baffle 41 is supported.

In the rainwater recovery mode, although most water flows in from the gap between the two cover plates 121, a part of water flowing in from the side edge still enters the drainage system through the water drain hole 122, and if a part of sundries such as leaves or plastic bags are placed on the water drain hole 122, the entering speed of rainwater can be greatly influenced, as part of water enters the water storage cavity when the rainwater is filled into the upper sealing cavity 2, the backflushing structure 5 has a usable water source, wherein the backflushing structure 5 is specifically arranged, a backflushing structure 5 is further connected between the movable cover 1 and the upper sealing cavity 2, the water storage cavity is further sleeved outside the upper sealing cavity 2, the backflushing structure 5 comprises a connecting ring 51 welded at the top of the upper sealing cavity 2, a plurality of pumps 52 annularly arranged at the inner side of the connecting ring 51 are connected with a transmission pipe 53 inside the pumps 52, the bottom of the transmission pipe 53 is communicated with the water storage cavity, the pumps 52 can be controlled by the same main platform, and can be started at fixed time by embedding a timing circuit, when the water storage cavity is stored in the water storage cavity, the water storage cavity can be continuously discharged to the water storage cavity through the pumps 53 without impacting the water storage cavity, and the water storage cavity can be continuously discharged to the water storage cavity without impacting the water storage cavity after the water storage cavity is continuously, and the water storage cavity is continuously discharged to the water storage cavity is continuously without a long time when the water storage cavity is no water storage cavity is required to be discharged.

It should be emphasized that the different pump 52 may be aligned with different drain holes 122 to simultaneously impact different drain holes 122, thereby cleaning the different drain holes 122 of debris that may be present.

In the treatment process of the drainage system, the specific quantity of the rainwater is most difficult to judge, when the rainwater is recovered, when all the rainwater is required to be drained quickly, no influence is caused to roads, the specific threshold value is difficult to judge, and for the situation, the backflow detecting structure 6 comprises a locating ring 61 clamped at the middle section of the inner side of the upper sealing cavity 2, a plurality of water guide inclined blocks 62 which are inserted on the locating ring 61 and are annularly arranged, a water immersion sensor 63 which is embedded in the water guide inclined blocks 62, the water immersion sensor 63 is electrically connected with the first rotating motor 132 and the pushing piece 442, firstly, the locating ring 61 is positioned at the middle section of the inner side of the upper sealing cavity 2, the distance is a dangerous value, when the threshold value is exceeded, the rainwater has a probability of directly rushing through the movable cover 1 and the upper sealing cavity 2 to directly flow backward to the ground, therefore, when the threshold value is exceeded, an alarm is formed, and then, in a normal water guiding state, water flows downwards along the water guiding inclined block 62, the normal water draining state is not affected, the water sensor 63 is positioned in the water guiding inclined block 62, the water guiding inclined block 62 is hollow, the water sensor 63 is protected from the upper side, no influence is caused by waste water or rainwater flowing down from the upper side, only the rainwater rising from the lower side submerges the water sensor 63, once the water sensor 63 receives water, the water level of the rainwater is indicated to rise reversely, so that the water sensor 63 transmits signals to start the first rotating motor 132 and the pushing member 442, and the signal transmission principle is the same as the electric signal principle.
