Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

the water level monitoring modules are mainly distributed in an underground waterlogging 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 height information from the water level monitoring module in real time and sending an alarm signal when the water level height 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 is in positive correlation with the levels of the alarm signal;
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;

The working principle of the intelligent waterlogging draining module is as follows:
the receiver 19 starts the adjusting motor 20 after receiving the drainage signal, and the adjusting motor 20 is a stepping motor, that is, the adjusting motor 20 does not work all the time, but works for a short time, and stops and locks after working for a short time; during 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 to the driving shaft 22, the fourth bevel gear 25 drives the third bevel gear 24 fixed to 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 is matched with one rack 26 by a straight gear 23 fixed on the driving shaft to drive one sliding piece 6 to slide along a sliding rod 28;
the driven shaft 29 is matched with the other rack 26 by using a straight gear 23 fixed on the driven shaft to drive the other sliding piece 6 to slide along the sliding rod 28;
the sliding directions of the two sliding pieces 6 are opposite, so that the scissor lifting structure 4 is deformed, the distance between the lifting platform 2 and the mounting base 1 is adjusted, and the height of the lifting platform 2 is adjusted;
meanwhile, the rotating fastening shaft 7 drives the connecting pipe 8 to rotate 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 lead screw 14 further rotates, the rotating lead screw 14 drives the solenoid 15 to move along the radial direction of the mounting seat 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 seat 1 and the inspection well is improved.
Furthermore, the driven shaft 29 drives the flywheel to rotate via the transmission 30, which adjusts the governor so that the suction pump 3 operates.
Because the adjusting motor 20 is a stepping motor, when the lifting platform 2 is lifted for a certain height, the water pump 3 works, and the connection strength of the mounting base 1 and the inspection well is adjusted; the lifting platform 2 is not lifted any more, but the current height is kept unchanged, meanwhile, the water suction pump 3 is kept working under the current power, and the connection strength of the mounting base 1 and the inspection well is also fixed.
3 work drainage waterlogging of suction pump, along with the work of suction pump 3, the ponding degree of depth of current position can have two kinds of situations:
one is that the rainfall speed is higher than the current drainage speed of the water pump 3, the water level height is higher and higher;
at the moment, the level of the alarm signal sent by the alarm module is continuously enhanced, so that the intensity of the drainage signal sent by the central control center is enhanced, the intensity of the drainage signal received by the receiver 19 is also continuously enhanced, the receiver 19 sends an instruction to the adjusting motor 20, the adjusting motor 20 works again, the height of the lifting platform 2 is raised, the height of the water pump 3 is raised, and the problem that the water pump 3 cannot drain water effectively due to the fact that accumulated water submerges the water pump 3 is avoided;
meanwhile, the power of the water suction pump 3 is increased, the water drainage speed of the water suction pump 3 is increased, the connection strength between the mounting base 1 and the inner wall of the inspection well is increased, and collapse caused by unstable gravity center after the height of the water suction pump 3 is increased is avoided.
The rainfall speed is lower than the drainage speed of the retaining wall water pump 3, the water level height is gradually reduced, the height of the lifting platform 2 is gradually reduced, the power of the water pump 3 is reduced, and the connection strength of the mounting base 1 and the inner wall of the inspection well is reduced adaptively; the height of the water pump 3 is reduced, so that the load of the water pump 3 can be prevented from being increased due to the fact that the height of the water pump 3 and the height of the liquid level of accumulated water are too high, and the water pump 3 can be prevented from being burnt out when being in a high-power output state for a long time by reducing the power of the water pump 3; the connection strength of the mounting base 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 clamping block 18 is prevented from being damaged and abraded under the condition of high extrusion force for a long time.
The above embodiments are exemplary rather than limiting, and embodiments of the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
