Detailed Description
The following specific examples are intended to be illustrative of the invention and are not intended to be limiting, as modifications of the invention will be apparent to those skilled in the art upon reading the specification without inventive contribution thereto, and are intended to be protected by the patent law within the scope of the appended claims.
The invention relates to an underground water level early warning and waterlogging prevention facility, which comprises a water inlet chamber 1 and a water accumulation chamber 2, wherein a buoyancy member 4 capable of floating in water is arranged in the water accumulation chamber 2, and the top of the water accumulation chamber 2 is provided with an extension port 21 for extending out of the buoyancy member 4; the water inlet chamber 1 is provided with a first water filling port 11, the water accumulation chamber 2 is provided with a second water filling port 22, and a water conveying pipeline 3 with one end communicated with the first water filling port 11 and the other end communicated with the second water filling port 22 is arranged between the water inlet chamber 1 and the water accumulation chamber 2; the water conduit 3 comprises an early warning threshold section 35, one end of the early warning threshold section 35 having a first port 351 and the other end having a second port 352, the first port 351 being higher than the rest of the water conduit 3 and higher than the first water filling port 11, the second port 352 being higher than the second water filling port 22 or being level with the second water filling port 22. In actual use, the water inlet chamber 1 is communicated with a sewer, and water in the sewer can enter the water inlet chamber 1, so that the water level of the water inlet chamber is the water level of the sewer, the water level of the sewer rises due to external factors such as storm, and the water level of the water inlet chamber 1 rises; at the initial stage of water level rising, the water level does not reach the height of the early warning threshold section 35, and at this time, the water in the water inlet chamber 11 cannot enter the water accumulation chamber 2 through the water delivery pipeline 3; when the water level is immersed in the first water filling port 11 and then continuously rises to reach the height of the first port 351 in the early warning threshold section 35, water starts to enter the early warning threshold section 35 from the first port 351 and then enters the water accumulation chamber 2 through the early warning threshold section 35, and in the process, although water still flows into the water inlet chamber 1, the water level in the water inlet chamber 1 is basically not raised any more, and redundant water enters the water accumulation chamber 2; until the water level in the water accumulation chamber 2 is increased until the second water filling port 22 is immersed, a section of air column is formed inside the water conveying pipeline 3 because the two ends of the water conveying pipeline are sealed by water, once the air pressure of the section of air column reaches a critical point slightly larger than the external atmospheric pressure, water cannot enter the water accumulation chamber 2 through the water conveying pipeline 3, and the water level in the water accumulation chamber 2 stops to increase; the buoyancy member 4 in the water accumulation chamber 2 rises along with the water level and partially extends out of the water accumulation chamber 2, and when in actual use, the buoyancy member extending out of the road surface can draw attention of people, and the water level condition of a sewer is transferred to pedestrians on the road surface to play a role in warning; in addition, if this facility sets up the gate at the low-lying places of topography such as underground garage or subway station, the buoyancy piece 4 that stretches out the road surface can also play the blocking effect to the road surface water, prevents ponding inflow above-mentioned low-lying place of topography, avoids appearing the waterlogging.
In actual use, the setting height of the early warning threshold section 35 can be selected according to the field condition, because the water enters the water accumulation chamber 2 through the water conveying pipeline 3 only after the water level in the water inlet chamber 1 reaches the height of the first port 351 in the early warning threshold section 35, so that the buoyancy member 4 rises along with the water level and stretches out of the water accumulation chamber 2 to play a role in warning and retaining water, the height of the first port 351 of the early warning threshold section 35 is the threshold of the facility for early warning the water level of the sewer, and only if the water level of the sewer reaches the threshold, the facility starts to stretch out the buoyancy member 4 out of the water accumulation chamber 2 for water level early warning and retaining; as long as the water level in the intake chamber 1 has not reached this threshold, it is indicated that the water level of the sewer is within a safe range, and no pre-warning is required. In this embodiment, the upper end of the buoyancy member 4 is located at the top of the water accumulation chamber 2 when water does not enter the water accumulation chamber 2, so long as the water level in the water accumulation chamber 2 rises, the buoyancy member will rise and extend out of the water accumulation chamber, and early warning is ensured in time.
The pre-warning threshold section 35 is a part of the water pipe 3, so the pre-warning threshold section 35 is communicated with the first water filling port 11 through the rest part of the water pipe 3, so when water in the water inlet chamber 1 continuously rises after submerging the first water filling port 11, a water column with the water level being consistent with the water level in the water inlet chamber 1 can also appear in the part of the water pipe 3, which is communicated with the pre-warning threshold section 35 and is communicated with the first water filling port 11, when the water level of the water column reaches the first port 351 in the pre-warning threshold section 35, water enters the pre-warning threshold section 35 and enters the water accumulation chamber 2 through the pre-warning threshold section 35, if the pre-warning threshold section 35 is a tortuous pipeline, the water easily generates a local section of air column at the tortuous position inside the pre-warning threshold section, so that water cannot flow in the pre-warning threshold section 35, the pre-warning threshold section 35 is a pipeline which is horizontally arranged can flow along the bottom of the inner cavity of the pre-warning threshold section 35 as long as the water reaches the first port 351, the upper part of the inner cavity of the pre-warning threshold section 35 can not be guaranteed to be smoothly filled with water, the pre-warning threshold section 35 can be smoothly filled with water, and the water can be smoothly impacted by the water pipe 3, and the pre-warning threshold section can be smoothly arranged on the water pipe 3, and the water flow can be stably, and the pre-warning threshold section can be guaranteed, and the water flow can be stably and stably, and the water flow can be guaranteed.
The first port 351 of the early warning threshold section 35 is higher than the first water filling port 11, so that the first port 351 and the first water filling port 11 need to be communicated with each other through the rest of the water conveying pipeline 3, specifically, in this embodiment, the water conveying pipeline 3 further includes a first water conveying section 31 for communicating the first port 351 and the first water filling port 11, the whole first water conveying section 31 is not higher than the first port 351, preferably the first water conveying section 31 is a straight pipeline, and before the water level of the water inlet chamber 1 reaches the height of the first port 351 of the early warning threshold section 35, the water level in the first water conveying section 31 is consistent with the water level of the water inlet chamber, and when the water level of the water inlet chamber 1 continues to rise, the water level of the first water conveying section 31 rises towards the first port. The advantage of this design lies in that the water level of intake chamber 1 has been reflected to first water delivery section 31, first water delivery section 31 is isolated between intake chamber 1 and early warning threshold section 35, because in the circumstances that a large amount of rainwater got into intake chamber 1, intake chamber 1's the surface of water is in unstable rocking state, its water level height is inaccurate, and the water in first water delivery section 31 is in the narrow and small pipeline in space, and can not receive intake chamber 1 environment's influence, its surface of water is in comparatively stable state, the actual water level height of reflection intake chamber 1 that can be comparatively accurate, guarantee only after intake chamber 1's actual water level height reaches the height of early warning threshold section 35 first port 351 in can flow into the hydrops chamber 2.
The pre-warning threshold section 35 is a horizontally and transversely arranged pipeline, so that as long as the water level in the first water delivery section 31 continues to rise, water in the pre-warning threshold section 35 can flow from the first port 351 to the second port 352 and finally enter the water accumulation chamber 2 through the second water filling port 22. There are two embodiments of the connection between the pre-warning threshold segment 35 and the second filler 22; the first is that the second water filling port 22 is leveled with the second port 352 of the early warning threshold section 35, and the second port 352 is directly communicated with the second water filling port 22, so that the water in the early warning threshold section 35 directly flows through the second water filling port 22 and enters the water accumulation chamber 2; the second type is that the second port 352 of the early warning threshold section 35 is higher than the second water filling 22 port, the water pipe 3 further comprises a second water conveying section 32, the second water conveying section 32 is communicated with the second port 352 and the second water filling 22 port, the whole second water conveying section 32 is lower than the second port 352, water in the early warning threshold section 35 enters the second water conveying section 32 through the second port 352 and then enters the water accumulation chamber 2 through the second water filling 22 port, the setting position of the second water filling 22 port is lower, the early warning threshold section 35 is erected on the first water conveying section 31 and the second water conveying section 32, when the water level in the water accumulation chamber 2 rises to submerge the second water filling 22 port, a section of air column is formed in the second water conveying section 32, and the subsequent water cannot flow through the water pipe 3 any more, so that the early warning threshold section 35 is provided with an exhaust hole, the air column is communicated with the outside and always keeps consistent with the outside air pressure, and the water flowing through the water conveying pipe 353 can always and keep the water flowing through the water conveying pipe 3. In the first embodiment, the height of the second water filling port 22 is consistent with the second port 352 of the early warning threshold section 35, and if the area occupied by the buoyancy member 4 on the water surface of the water accumulation chamber 2 is large, the water is difficult to fall directly below the buoyancy member 4 after falling from the second water filling port 22, and the floating of the buoyancy member is affected. In the second embodiment, the second water filling port 22 is arranged at a lower position of the water accumulation chamber 2, so that water in the water delivery pipeline 3 can enter the lower part of the buoyancy member 4 conveniently, interference of the water on the buoyancy member 4 in the process of entering the water accumulation chamber 2 is avoided, meanwhile, the early warning threshold section 35 is erected on the first water delivery section 31 and the second water delivery section 32, and the overall structural stability of the water delivery pipeline 3 is improved.
In this embodiment, the water level in the water accumulation chamber 2 can rise to be equal to the water level in the water inlet chamber 1, and if rainwater still enters the water inlet chamber 1, the water levels in the water inlet chamber 1 and the water accumulation chamber 2 rise together until the water delivery pipeline 3 is completely filled with water, the early warning threshold section 35 does not play a role any more, the water inlet chamber 1 and the water accumulation chamber 2 can be regarded as a container, and the water delivery pipeline 3 plays a role of delivering water to the water accumulation chamber 2 continuously. In actual use, the pre-warning threshold section 35 is typically arranged in an area near the top of the facility, so that the pre-warning threshold section 35 approaches the actual road surface, once the water level in the water inlet chamber 1 reaches the height of the pre-warning threshold section 35, the water level is in the condition of being about to overflow onto the road surface, and then the rainwater continuing to enter the water inlet chamber 1 enters the water accumulation chamber 2 through the water pipe 3, so that the buoyancy member 4 rises along with the water level until the water level in the water accumulation chamber 2 rises to be consistent with the water level in the water inlet chamber 1, reaches a limit state, and then the rainwater continues to enter the water inlet chamber 1, so that the water level in the water inlet chamber 1 continues to rise until the water overflows onto the road surface.
On the basis of the above embodiment, it is preferable that the pre-warning threshold section 35 is detachably and fixedly connected with the first water delivery section 31 and the second water delivery section 32, and the first water delivery section 31 and the first water filling port 11 and the second water delivery section 32 and the second water filling port 22 are detachably and fixedly connected. Therefore, the first water delivery section 31 and the second water delivery section 32 with different lengths can be selected through disassembly and assembly, so that the height of the early warning threshold section 35 can be adjusted to adapt to different use conditions. In the above embodiment, since the first water delivery segment 31 is directly connected to the first port 351 and the first water filling port 11, the second water delivery segment 32 is directly connected to the second port 352 and the second water filling port 22, and the first water delivery segment 31 and the second water delivery segment 32 are preferably long and straight pipes, the first water delivery segment 31 and the second water delivery segment 32 are all inclined pipes, the structure is not stable, and if the height of the early warning threshold segment 35 is to be adjusted by replacing the first water delivery segment 31 and the second water delivery segment 32 with different lengths, the length of the early warning threshold segment 35 needs to be changed after each adjustment, and the early warning threshold segment 35 with different length specifications needs to be prepared. Therefore, the second improvement is preferred in this embodiment, the water pipe 3 further includes a first water filling section 33, a second water filling section 34 and a water draining section 36, the first water filling section 33 is communicated with the first water filling port 11 and transversely extends below the first water filling section 31, the second water filling section 34 is communicated with the second water filling port 22 and transversely extends below the second water filling section 32, the first water filling section 31 is vertical, the lower end of the first water filling section 31 is communicated with the first water filling section 33, the second water filling section 32 is vertical, the lower end of the second water filling section 32 is communicated with the second water filling section 34, the transverse arrangement of the first water filling section 33, the second water filling section 34 and the early warning threshold section 36 is that one end points to the water accumulating chamber 2 and the other end points to the left and right transverse arrangement of the water inlet chamber 1, and the extending directions of the three are consistent, so that the water pipe 3 forms a "several" shape structure with higher structural strength and stable structure; in addition, the drain section 36 communicates the first water filling section 33 with the second water filling section 34, the drain section 36 is supported in a lower notch in the overall structure of the water pipe 3, the structural strength of the water pipe 3 is further improved, the drain section 36 is provided with a valve 361, in the normal use process of the facility, the valve 361 is in a closed state, when water in the water accumulating chamber 2 needs to be drained, the valve 361 on the drain section 36 is opened, so that the water in the water accumulating chamber 2 is drained into the water inlet chamber 1, and finally drained into a sewer. Preferably, the extending direction of the drainage section 36 is consistent with the pre-warning threshold section 35, so that the pre-warning threshold section 35, the drainage section 36, the first water delivery section 31 and the second water delivery section 32 form a square frame, and the structural stability of the water delivery pipeline 3 is further improved. In this preferred embodiment, the first water delivery segment 31 and the second water delivery segment 32 are all vertically arranged, so that the pre-warning threshold segment 35 is preferably detachably and fixedly connected with the first water delivery segment 31 and the second water delivery segment 32, and the first water delivery segment 31 and the first water filling segment 33 and the second water delivery segment 32 and the second water filling segment 34 are also detachably and fixedly connected. When the height of the early warning threshold section 35 is adjusted, only the first water delivery section 31 and the second water delivery section 32 with different lengths are required to be replaced, the length of the early warning threshold section 35 is still unchanged, and only the early warning threshold section 35 with one length specification can be prepared. The present specification provides that the water accumulation chamber 2, the water delivery pipe 3 and the water inlet chamber 1 are arranged in order from left to right, the water inlet chamber 1 and the water accumulation chamber 2 are wide in the left-right direction and long in the front-rear direction. When in actual use, the ponding chamber 2 is close to the low-lying position, the intake chamber 1 is far away from the low-lying position, so that the buoyancy member 4 extending out of the ponding chamber 2 can block the rainwater on the ground, and the rainwater overflowing from the intake chamber 1 to the ground is blocked by the buoyancy member 4, so that the rainwater is effectively prevented from entering the low-lying position.
Further, it is preferable that the first water filling port 11 is located at the bottom area of the water inlet chamber 1, and because the whole of the early warning threshold section 35 is higher than the first water filling port 11, the adjustable height range of the early warning threshold section 35 is enlarged to adapt to different use situations. In this embodiment, the buoyancy member 4 includes a base 42 and a baffle 41 fixed together, the base 42 is located below and has a width in the left-right direction greater than the width of the baffle 41 and the width of the extending opening 21 in the left-right direction, and the width of the baffle 41 is slightly smaller than the width of the extending opening 21, so that when water enters the water accumulation chamber 2 and the buoyancy member 4 integrally begins to float, the baffle 41 can extend from the extending opening 21, and the base 42 cannot leave the water accumulation chamber 2 all the time, so that the buoyancy member 4 is limited after reaching the maximum floating height and cannot break away from the water accumulation chamber 2, and the baffle 41 in the buoyancy member 4 can also block the water accumulation on the ground to prevent the water accumulation from flowing into the low-lying place. Since the buoyancy member 4 can move up and down in the water accumulation chamber 2, a gap is necessarily formed between the buoyancy member 4 and the inner wall of the outlet 21, if the water level is still rising after the water accumulation chamber 2 is filled with rainwater, the rainwater in the water accumulation chamber 2 may overflow to the ground from the left gap and the right gap between the buoyancy member 4 and the outlet 21, the left side of the buoyancy member 4 is a protected low-lying place, the right side of the buoyancy member 4 is a ground with water accumulation, and the rainwater overflowing from the right gap of the buoyancy plate 4 can be blocked by the buoyancy member 4, and the rainwater overflowing from the left gap of the buoyancy member directly flows into the low-lying place beyond the buoyancy member 4.

The early warning threshold section 35, the drainage section 36, the first water delivery section 31 and the second water delivery section 32 form a square frame, four pipelines are mutually supported, the whole structure is stable, the first water filling section 33 and the second water filling section 34 are respectively communicated with the water inlet chamber 1 and the water accumulation chamber 2 at two sides of the square frame, the square frame is structurally erected, and the whole structural strength and the whole stability of the water delivery pipeline 3 are improved. The water delivery pipeline 3 is taken as a whole, can be produced as a whole during processing and manufacturing, and can be directly installed on site.
In order to improve the efficiency of the delivery of the rainwater, it is preferable that a plurality of water delivery pipes 3 are arranged side by side between the water inlet chamber 1 and the water accumulation chamber 2, each water delivery pipe 3 is correspondingly communicated with one first water filling port 11 and one second water filling port 22, and the water delivery pipes 3 are all manufactured and formed according to the above preferred embodiment in the same structure and specification. In the first embodiment of the arrangement mode of the water conveying pipelines 3, all the water conveying pipelines 3 are arranged side by side at the same height, the pipe walls of the water conveying pipelines 3 are completely sealed, the early warning threshold sections 35 of the water conveying pipelines 3 are provided with the exhaust holes 353, because the structures and the specifications of all the water conveying pipelines 3 are the same, the height of the early warning threshold sections 35 of each water conveying pipeline 3 is consistent, when the water level in the water inlet chamber 1 reaches the height of the first port 351 of the early warning threshold section 35, all the water conveying pipelines 3 start to convey the water entering the early warning threshold sections 35 into the water accumulation chamber 2, and the function of arranging the water conveying pipelines 3 is mainly to improve the conveying capacity of the facility on rainwater and the rainwater conveying efficiency. In this embodiment, it is preferable that the upper end of the first water delivery segment 31 and the first port 351 of the early warning threshold segment 35 and the upper end of the second water delivery segment 32 and the second port 352 of the early warning threshold segment 35 are both detachably connected, and the lower end of the first water delivery segment 31 and the first water filling segment 33 and the lower end of the second water delivery segment 32 and the second water filling segment 34 are both detachably connected. Therefore, the height of the early warning threshold section 35 can be adjusted according to actual conditions, when the height of the early warning threshold section 35 is adjusted, only the first water delivery section 31 and the second water delivery section 32 with different lengths are required to be replaced, the length of the early warning threshold section 35 is still unchanged, and only the early warning threshold section 35 with one length specification can be prepared.
In the second embodiment of the arrangement mode of the plurality of water pipes 3, the pipe walls of the water pipes 3 are completely sealed, and the pre-warning threshold sections 35 in any two water pipes 3 have a spacing in the vertical height direction, so that all pre-warning threshold sections 35 form a low-to-high arrangement relationship in the vertical height direction, and because the structures and specifications of all water pipes 3 are completely consistent and are arranged side by side, all water pipes 3 also form the same low-to-high arrangement relationship as the pre-warning threshold sections 35 in the vertical height direction; when the water level of the water inlet chamber 1 starts to continuously rise, the water level can reach the height of the early warning threshold section 35 with the lowest height at first, and at the moment, the water pipe 3 where the early warning threshold section 35 with the lowest height is positioned can convey rainwater into the water accumulation chamber 2; because the water delivery pipe 3 is completely sealed after being closed, when the second water filling port 22 of the water delivery pipe 3 for delivering rainwater is immersed by water in the water accumulation chamber, the water delivery pipe 3 cannot continuously deliver the rainwater, and although the water level of the water inlet chamber 1 continuously rises, the water level of the water accumulation chamber 2 cannot rise any more; until the water level in the water inlet chamber 1 rises to the height of the foremost early warning threshold section 35, at this time, the water pipe 3 where the foremost early warning threshold section 35 is located starts to convey rainwater into the water accumulation chamber 2, the water level in the water accumulation chamber 2 starts to rise for the second time, until the second water filling port 22 connected with the water pipe 3 is immersed, and the water pipe 3 stops conveying rainwater; then the water level in the water inlet chamber 1 continues to rise until the water level rises to the height of the early warning threshold section 35 with the third last height, the water pipeline 3 with the early warning threshold section 35 with the third last height starts to convey rainwater, and so on, the water pipeline 3 sequentially conveys the rainwater according to the arrangement relation from low to high, the intermittent rising of the water level in the water accumulation chamber 2 is realized, the buoyancy piece 4 in the water accumulation chamber 2 is caused to intermittently rise, and therefore different water level grades in the water inlet chamber 1 are divided, and the buoyancy piece 4 plays a role of graded early warning. When the water level of the water inlet chamber 1 is low, only the water pipe 3 with the lowest height conveys rainwater into the water accumulation chamber 2, and the water level of the water accumulation chamber 2 stops rising after the second water filling port 22 connected with the water pipe 3 is immersed, and the part of the buoyancy member 4 extending out of the water accumulation chamber 2 is short, so that the water level warning and reporting function of a sewer is realized, and normal traffic of a road surface is not hindered; only when the water level of the water inlet chamber 1 rises to reach the height of the next early warning threshold section 35, the water level of the water accumulation chamber 2 rises for the second time, the buoyancy member 4 also rises for the second time, the second water level early warning is realized, and intermittent multiple water level early warning is realized along with the continuous rising of the water level of the water inlet chamber 1.
When the water level of the water inlet chamber 1 reaches the height of the highest early warning threshold section 35 and the highest water delivery pipeline 3 delivers rainwater, the second water filling port 22 connected with the water delivery pipeline 3 is immersed to stop delivering rainwater, at this time, the water level of the water inlet chamber 1 is close to the road surface, the water in the water inlet chamber 1 is about to overflow onto the road surface, a serious stage is reached, the water level of the water accumulation chamber 2 is not consistent with the water level of the water inlet chamber 1, and the water level of the water inlet chamber 1 cannot be reflected in real time under the worst condition. Therefore, in this embodiment, the vent hole is preferably formed in the pre-warning threshold section 35 with the highest height, so that when the water level of the water inlet chamber 1 reaches the height of the pre-warning threshold section 35 with the highest height, the water pipe 3 with the highest height continuously conveys rainwater, and when the water level of the water accumulation chamber 2 reaches the pre-warning threshold section 35 with the highest height, the water level of the water accumulation chamber 2 and the water level of the water inlet chamber 1 in the subsequent water level rising process are kept consistent, and thus, the water level of the water inlet chamber 1 can be reflected in real time by the buoyancy member 4, and a good pre-warning effect is achieved.
In this embodiment, the second water filling sections 34 are laterally disposed left and right and are connected to the second water filling port 22, and the second water filling sections 34 are also pipes with a section of cross-sectional area that is consistent throughout, so the shape and size of the second water filling port 22 are preferably consistent with those of the nozzle of the second water filling section 34, and since the second water filling port 22 connected to each water pipe 3 is submerged and stops delivering rainwater, the width of the second water filling port 22 in the up-down direction determines the maximum delivering amount of rainwater by the water pipe 3, the up-down width of the second water filling port 22 is smaller, in this embodiment, the second water filling sections 34 in any two water pipes 3 are preferably spaced in the up-down height direction, so that overlapping portions of two second water filling sections 34 adjacent in height are avoided, and loss of delivering amount of rainwater by the water pipe 3 is avoided. Further, preferably, the second water filling section 34 is detachably and fixedly connected with the second water delivery section 32 through a special-shaped water pipe connector, and the second water filling section 34 is also detachably and fixedly connected with the second water filling port 22, so that the second water filling sections 34 with different pipe orifice sizes can be selected according to actual requirements to adjust the maximum delivery amount of the water delivery pipeline 3 to rainwater.
In the scheme of realizing intermittent type stage water level early warning, the setting of the water pipe 3 can also adopt a second implementation mode, the pipe wall of the water pipe 3 is completely sealed, the early warning threshold sections 35 in any two water pipes 3 are spaced in the vertical height direction, the exhaust holes 353 are formed in the early warning threshold sections 35 of each water pipe 3, and the water pipes 3 are provided with pressure valves 331 except for the highest water pipe 3, and the rest water pipe 3 is provided with pressure valves 33 in the first water filling sections 33. The threshold value of the pressure valve 331 in each first water filling section 33 is set in advance, since all the water pipes 3 have a height difference in height as a whole, the first water filling sections 33 to which each water pipe 3 is connected are formed in the height-wise arrangement order as well, which is in accordance with the height-wise arrangement order of the water pipes 3 in which it is located, so the pressure valves 331 provided in the first water filling sections 33 have the same height-wise arrangement order as the first water filling sections 33, the threshold value of each pressure valve 331 is also set in the height-wise arrangement order of the pressure valves 331 as the pressure valves 331, the threshold value of the pressure valve 331 with the lowest height is the lowest, and the threshold value of the pressure valve 331 with the highest height is the highest. When the water level in the water inlet chamber 1 reaches the height of the early warning threshold section 35 of one of the water delivery pipelines 3, the water delivery pipeline 3 conveys rainwater to the water accumulation chamber 2, the water level in the water inlet chamber 1 is not increased in the conveying process, the water pressure born by the pressure valve 331 in the first water filling section 33 connected with the water delivery pipeline 3 is kept unchanged, the pressure value is a threshold value, when the water level in the water inlet chamber 1 reaches the height of the early warning threshold section 35 of one of the water delivery pipelines 3, the pressure value slightly larger than the threshold value can be set as the threshold value of the pressure valve 331 in use, and after the water level in the water accumulation chamber 2 rises to the height of the early warning threshold section 35 in the water delivery pipeline 3, the water level in the water accumulation chamber 2 is level with the water level in the water inlet chamber 1 and starts to rise synchronously, the pressure born by the pressure valve 331 increases and reaches the threshold value of the pressure valve 331, the pressure valve 331 is closed, and the water delivery pipeline 3 stops conveying rainwater. The pressure valve 331 in each water pipe 3 is arranged in this way, and intermittent water level early warning can be realized.
In a further improvement, the buoyancy member 4 preferably comprises a baffle 41 capable of extending out of the water accumulation chamber 2, the top of the baffle 41 is provided with a slope 411, and the side, close to the water inlet chamber 1, of the slope 411 is lower than the side, far away from the water inlet chamber 1, so that in the scheme of intermittent stage water level early warning, when the water level of the water inlet chamber 1 is lower, the vehicle can still pass through the baffle 41 from the slope 411 under the condition that the part, extending out of the water accumulation chamber 2, of the buoyancy member 4 is shorter. When the urban inland inundation is finished, the water level of the sewer is reduced, and the water level of the water inlet chamber 1 is also reduced, at the moment, the rainwater in the water accumulation chamber 2 can be discharged into the water inlet chamber 1 and finally discharged into the sewer by only opening the valve 361 on the water discharge section 36. The water accumulation chamber 2, the water delivery pipeline 3 and the water inlet chamber 1 in the water logging prevention facility are sequentially arranged from left to right, the depth of the water accumulation chamber 2 and the water inlet chamber 1 is in the length along the front-back direction, and when the water logging prevention facility is arranged at an inlet and an outlet of a low-lying place, the whole facility is required to be transversely arranged in front of the inlet and the outlet of the low-lying place along the front-back direction, so that the length of the water logging prevention facility in the front-back direction is required to be certain. The waterlogging prevention facility is usually limited in length during processing and manufacturing, and is produced singly, so that a plurality of waterlogging prevention facilities can be spliced together in the front-back direction during specific implementation, and the length requirement of a use site is met. In the waterlogging prevention facility of mutual concatenation, two adjacent ponding rooms 2 are inside to communicate each other, and two adjacent intake chambers 1 are inside to communicate each other, set up respectively on the front and back both sides wall of ponding room 2 and intake chamber 1 and set up pin thread and box to satisfy the concatenation of two waterlogging prevention facilities.
