Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments.

the water level monitoring module is fixedly arranged in the underground drainage pipe network and used for monitoring the water level height in the underground drainage pipe network;
the water level monitoring modules are mainly distributed in an underground drainage pipe network corresponding to the urban low-lying place;
the alarm module is communicated with the water level monitoring module and is used for receiving the water level information from the water level monitoring module in real time and sending out an alarm signal when the water level in the underground drainage pipe network exceeds the preset value of the alarm module;
the alarm signal is divided into a plurality of levels, and the water level height and the level of the alarm signal are in positive correlation;
The central control center is interacted with the alarm module, receives an alarm signal sent by the alarm module, and can also send a control instruction to the alarm module;
When the urban flood occurs, the water level monitoring module monitors that the water level in the underground drainage pipe network exceeds the preset value of the alarm module, and an alarm signal is sent to the central control center through the alarm module;
When flood weather does not occur in the city and the water pipe is broken due to underground pipeline excavation, the water level in a certain underground drainage pipe network is increased, and the water level height exceeds the preset value of the alarm module, a control instruction for stopping alarm can be generated to the alarm module through the central control center, and the alarm signal is cancelled.
The intelligent drainage module is connected with the central control center and is used for draining excessive accumulated water in the current underground drainage pipe network when the central control center sends drainage signals to the intelligent drainage module, and the strength of the drainage signals corresponds to the alarm signal level sent by the alarm module.
The water level monitoring module is arranged at the position of an underground drainage pipe network of a relatively low city in a fixed point mode, and the intelligent drainage module is movably arranged;
According to severe stormwater weather early warning issued by weather forecast, the intelligent drainage module is arranged in an inspection well of an underground drainage pipe network provided with a water level monitoring module in advance, so that the system can effectively drain water when stormwater comes temporarily; and in sunny days, the intelligent drainage module can be detached from the inspection well.
The intelligent drainage modules are flexibly distributed and can be flexibly set in advance according to the area covered by the heavy rain; compared with the arrangement at each low-lying place of the city, the method has higher flexibility and saves cost.

The working principle of the intelligent drainage module in the invention is approximately as follows:
The receiver 19 starts the regulating motor 20 after receiving the waterlogging draining signal, the regulating motor 20 is a stepping motor, namely, the regulating motor 20 does not always work and only works for a small period of time, and stops and locks after working for a small period of time; in the process of the operation of the adjusting motor 20, the adjusting motor 20 drives the driving shaft 22 to rotate, the driving shaft 22 drives the fourth bevel gear 25 and the fastening shaft 7 to rotate through the third bevel gear 24 fixed on the driving shaft 22, the fourth bevel gear 25 drives the third bevel gear 24 fixed on the driven shaft 29 to rotate, so that the driven shaft 29 also rotates, and the rotation directions of the driven shaft 29 and the driving shaft 22 are opposite;
The driving shaft 22 cooperates with one of the racks 26 by means of a spur gear 23 fixed thereto, driving one of the sliding members 6 to slide along a sliding rod 28;
the driven shaft 29 cooperates with the other rack 26 by means of the spur gear 23 fixed thereon, driving the other slide 6 to slide along the slide bar 28;
The sliding directions of the two sliding parts 6 are opposite, so that the scissor lifting structure 4 is deformed, the distance between the lifting table 2 and the mounting seat 1 is adjusted, and the height of the lifting table 2 is adjusted;
Simultaneously, the connecting pipe 8 is driven to rotate by the rotating fastening shaft 7 through the clamping key 10, the connecting pipe 8 drives the first bevel gear 12 to rotate, the first bevel gear 12 drives the second bevel gear 13 to rotate, the screw rod 14 is further enabled to rotate, the screw rod 14 is rotated to drive the screw tube 15 to move along the radial direction of the mounting base 1 under the action of the wing plate 16 and the wing groove, the extrusion force of the clamping block 18 and the inner wall of the inspection well is adjusted, and the connection strength of the mounting base 1 and the inspection well is improved.
In addition, the driven shaft 29 drives the speed regulating wheel to rotate through the transmission part 30, so that the speed regulator is regulated, and the water pump 3 works.
Since the adjusting motor 20 is a stepping motor, when the lifting platform 2 is lifted by a certain height, the water pump 3 works, and after the connection strength between the mounting seat 1 and the inspection well is adjusted; the lifting table 2 is not lifted any more, but the current height is kept unchanged, meanwhile, the water pump 3 is kept to work under the current power, and the connection strength of the mounting seat 1 and the inspection well is also fixed.
The water suction pump 3 works to drain waterlogging, and along with the work of the water suction pump 3, the ponding depth of the current position can have two kinds of conditions:
one is that the rainfall speed is higher than the current drainage speed of the water pump 3, and the water level height is higher and higher;
At this time, the alarm signal level sent by the alarm module is continuously enhanced, so that the intensity of the drainage signal sent by the central control center is continuously enhanced, the intensity of the drainage signal received by the receiver 19 is also continuously enhanced, and an instruction is sent to the adjusting motor 20 through the receiver 19, so that the adjusting motor 20 works again, the height of the lifting table 2 is raised, the height of the water pump 3 is raised, and the phenomenon that the water pump 3 cannot effectively drain water due to the flooding of accumulated water on the water pump 3 is avoided;
meanwhile, the power of the water pump 3 is increased, the drainage speed of the water pump 3 is increased, the connection strength of the mounting seat 1 and the inner wall of the inspection well is increased, and collapse caused by unstable gravity center after the height of the water pump 3 is increased is avoided.
The other is that the rainfall speed is smaller than the drainage speed of the retaining wall water pump 3, so that the water level is lower and lower, the height of the lifting platform 2 is reduced slowly, the power of the water pump 3 is reduced, and the connection strength of the mounting seat 1 and the inner wall of the inspection well is reduced adaptively; the reduction of the height of the water suction pump 3 can prevent the load of the water suction pump 3 from being increased due to the excessive height of the water suction pump 3 and the water accumulation liquid level, and the reduction of the power of the water suction pump 3 can prevent the water suction pump 3 from being burnt out when being in a high power output state for a long time; the connecting strength of the mounting seat 1 and the inner wall of the inspection well is reduced adaptively, the service life of the clamping block 18 can be prolonged, and the damage and abrasion of the clamping block 18 under the condition of high extrusion force for a long time are avoided.
The above-described embodiments are illustrative, not restrictive, and the technical solutions that can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention are included in the present invention.
