As shown in fig. 3, 7, 8 and 14, a buoyancy frame 482 is commonly installed at the lower end of the buoyancy rod 48 in a sliding fit manner, the buoyancy frame 482 is located between the upper end of the displacement rod 4912 and the lower end of the buoyancy rod 48, an electromagnet 483 is arranged at the connection position of the buoyancy frame 482 and the buoyancy rod 48, the electromagnet 483 is electrically connected with the control box 7 and the electromagnet 483 is attached to the outer wall of the buoyancy rod 48, when the liquid level is higher than a preset distance above the buoyancy frame 482, the frictional adsorption force provided by the electromagnet 483 to the buoyancy rod 48 by the buoyancy frame 482 is smaller than the upward thrust force applied by the buoyancy frame 484 in the water flow, buoyancy balls 4821 are uniformly installed in the middle of the buoyancy frame 482, a plurality of groups of air bags 484 are uniformly installed at equal intervals at the upper end of the buoyancy rod 48, the air bags 484 in the same group are all at the same height and the air bags 484 in the same group are circumferentially distributed on the buoyancy rod 48 at different positions, and the buoyancy ball 4821 and the air bag 484 are hollow structures.
As shown in fig. 1 and 2, the control box 7 integrates input, storage, control and output of electric energy and electric signals, the control box 7 collects and stores electric energy generated by photovoltaic power generation from the photovoltaic panel 10, meanwhile, the control box 7 provides stable power supply for the flow monitor 37, the pressure sensor 43 and the electromagnet 483 through the collected electric energy, and the electric signals generated in the flow monitor 37 and the pressure sensor 43 are collected and converted through the control box 7.
During specific work, at the initial stage of the installation of the well lid 1, the photovoltaic power generation amount of the photovoltaic panel 10 is low, at the moment, the collected power is supplied to the pressure sensor 43 in advance through the control of the control box 7, no power is supplied to the electromagnet 483, at the moment, under the action of the buoyancy ball 4821, the whole buoyancy frame 482 floats above the liquid level of the sewage, due to the common buoyancy of the buoyancy frame 482 and the buoyancy rod 48 in the liquid level, the top end of the buoyancy rod 48 abuts against the abutting block 411 and supplies a continuous upward pushing force to the abutting block 411, the pushing force applied to the abutting block 411 is further applied to the monitoring ring 410, the monitoring seat 47 further abuts against the pressure sensor 43 tightly through the power connection between the monitoring ring 410 and the monitoring rod 46, and then, the pressure value transmitted by the pressure sensor 43 at the moment is collected and converted through the control box 7, the previously measured sewage liquid level height value is used as a comparison, the pressure value at the moment is used as a measured initial value, after the numerical value measurement record is finished, the control box 7 supplies power to the electromagnet 483, and the electromagnet 483 generates magnetic force and is adsorbed on the buoyancy rod 48 after being electrified;
on the premise that the liquid level does not change, the pressure value received by the pressure sensor 43 is still the initial value, then, as time goes on and the external environment changes, when the liquid level in the bilge well 00 drops, the buoyancy frame 482 drops along with the drop of the liquid level, because the buoyancy frame 482 is adsorbed on the buoyancy rod 48 at this time, the buoyancy rod 48 is further pulled to synchronously slide downwards on the first slide rod 491, and in the process of dropping displacement, the abutting action on the abutting block 411 is gradually relieved, the pressure value applied to the pressure sensor 43 by the monitoring seat 47 is further reduced, at this time, the control box 7 only records and processes data, and does not give an alarm to the outside, when the liquid level in the bilge well 00 rises, because the buoyancy frame 482 and the buoyancy rod 48 are in a fixed connection state at this time, and the upper end of the buoyancy rod 48 at this time is abutted and limited by the abutting block 411, the buoyancy frame 482 does not rise with the rise of the liquid level;
then, when the liquid level continues to rise, the buoyancy frame 482 begins to gradually submerge into the water, as the depth of the buoyancy frame 482 submerges into the liquid level increases, the buoyancy force applied to the buoyancy frame 482 itself increases, the buoyancy force further forms a squeezing action on the abutting block 411 through the power transmission of the buoyancy rod 48, the pressure applied to the pressure sensor 43 by the monitoring seat 47 is further increased through the power connection between the monitoring ring 410 and the monitoring rod 46, then, the collection and calculation of the pressure value are performed through the control box 7, when the liquid level rises higher than the preset value above the buoyancy frame 482, the flow rate of the liquid in the sewer well 00 is correspondingly increased due to the increase of the liquid level, the liquid is blocked by the buoyancy ball 4821 in the flowing process to further generate vortex, a continuous upward thrust is applied to the buoyancy frame 482, and when the thrust force and the buoyancy force are added to be larger than the adsorption force of 483, the buoyancy frame 482 starts to generate relative displacement on the buoyancy rod 48 and moves upwards until the buoyancy frame 482 rises to a position where the magnetic adsorption force and the buoyancy are balanced, and the buoyancy frame 482 actively rises to a relatively gentle position, so that water flow flowing at the bottom of the sewage well 00 at the highest speed can be avoided, and overlarge vibration deflection of the buoyancy frame 482 caused by rapid current impact is avoided, and the running stability and the service life of the whole monitoring system are further influenced;
the abdication groove 441 is arranged to be adaptable to the inclined swing of the monitoring rod 46 in a certain degree of freedom, the spring rod 442 can provide restoring force in a certain degree of freedom for the monitoring rod 46 through self elastic force, so that the monitoring rod 46 is positioned at the central position of the abdication groove 441 when placed in a standing state, the accuracy degree of data in subsequent liquid level monitoring is facilitated for multiple times, by monitoring the abutting engagement between the spherical structure at the upper end of the seat 47 and the spherical recess on the pressure sensor 43 and the abutting engagement between the cylindrical projection 481 on the buoyancy rod 48 and the semi-circular recess on the abutment block 411, the variation in the distance of displacement of the float rod 48 up or down at different locations on the monitoring ring 410 can be further accommodated, the values of the thrust transmitted by the float rods 48 in different zones can be distributed and averaged by monitoring the torsional rotation of the ring 410 itself, therefore, the fluctuation change of the liquid level in the sewage well 00 is adapted, and the stability and the accuracy of the liquid level monitoring data are improved.
As can be seen from the buoyancy formula F-float = ρ liquid gV row, when the liquid level further rises and reaches the position of the air bag 484, as the air bag 484 is gradually submerged, the buoyancy value received by the buoyancy rod 48 is greatly changed compared with the case where the single buoyancy frame 482 is submerged, the pressure value received by the pressure sensor 43 is further caused to jump and change, and then, in the process of recording the jump and change of the data by the control box 7, since the bottom heights of the lowest set of air bags 484 and the sewage well 00 and the liquid level in the well are fixed values after the well lid 1 is completely installed, the jump and change of the pressure data at this time are recorded, the judgment basis of the rising distance of the liquid level from the initial position can be further used, since a plurality of sets of air bags 484 are installed in the vertical direction on the buoyancy rod 48, the number of sets of air bags in which the liquid level is not passed at this time can be further judged by recording the number of times of data jump and change, when the number of times of data jumping changes is consistent with the number of groups of the air bags 484, the fact that the height of the liquid level in the well at the moment reaches the height of the early warning water level is proved, and then an alarm is sent to the outside through the control box 7 to remind a worker to timely perform flood control and drainage operation.

When the rain water filter is in daily use, the flow monitor 37 and the guide rod 36 are in a relatively static state, the flow monitor 37 does not generate an electric signal, when a rainy season comes, part of rainfall and surface accumulated water can flow into the sewage well 00 through the water permeable holes 2, and when rainwater flows downwards through the water permeable holes 2, the rainwater further enters the inner side of the water filtering funnel 33, when the rainwater flow reaches a certain volume and flow rate, the fan blade in the flow monitor 37 is impacted by the rainwater to start rotating on the guide rod 36, so as to further drive the induction coil in the flow monitor to rotate around the induction slice, according to an electromagnetic induction effect, the induction slice performs magnetic induction line cutting operation and generates alternating current, the numerical value of the alternating current can generate corresponding change along with the rotating speed of the fan blade, when the rainfall increases, the rotating speed of the fan blade increases, the induced current generated by the induction slice is correspondingly increased, the current change at the moment is recorded by the control box 7 and is compared with the pressure change value collected on the pressure sensor 43, can further judge the source of water flow in the well, can provide a certain degree of filtering effect for the permeable hole 2 through the blocking rods 34 arranged circumferentially, avoids the blockage of the permeable hole 2 caused by the inflow of rubbish in the surrounding environment through shrub fallen leaves, further influencing the drainage effect of the well lid 1, the vibration spring 32 can make the water filtering funnel 33 and the material blocking rod 34 vibrate when being applied with external pressure, further improving the drainage and ejection effect of stains on the outer area of the water permeable hole 2, and by the guiding effect of the guide plate 35 on falling water flow, the water flow in the falling process can flow to the inner wall direction of the sewage well 00, and the impact force formed on the monitoring mechanism below is reduced.
When in work:
the first step is as follows: during the process of installing the system in the bilge well 00, the whole depth of the bilge well 00 to be monitored and the sewage level depth in the well at the moment are manually measured in advance, then the balancing weight 4922 is installed at the lower end of the second sliding rod 492, the rope sleeve 451 is in a rotatable state by manually pulling out the pin shaft 452 on the supporting frame 45, then the handle 4512 is manually rotated, the rope sleeve 451 is driven to rotate by the handle 4512, the rope 4511 is in a relaxed state by rotating the rope sleeve 451, after the rope sleeve 451 is relaxed, the first sliding rod 491 and the second sliding rod 492 are in a slidable stretching state, the first sliding rod 491 and the second sliding rod 492 can be prevented from rotating during the relative sliding process through the sliding clamping action between the outward protruding block 4911 and the inner groove 4921, then the handle 4512 is further rotated, and the second sliding rod 492 is pulled to move at the same time, so that the balancing weight 4922 at the lower end of the second sliding rod 492 is far away from the well lid 1, until the distance from the bottom end of the balancing weight 4922 to the lower end surface of the well lid 1 is the integral depth of the sewage well 00;
the second step: the pin shaft 452 is inserted and reset again manually, the rope sleeve 451 is further locked, then the well lid 1 is lifted and hoisted manually or by an existing hoisting device, the whole system is further lifted and moved to the position above the sewage well 00 to be monitored, then hoisting operation on the well lid 1 is removed, installation and positioning operation of the well lid 1 and the well mouth of the sewage well 00 is carried out, in the process that the well lid 1 moves to the well mouth of the sewage well 00, the first slide bar 491 and the second slide bar 492 are aligned linearly and the rope 4511 is in a stretched state under the pulling of the self gravity of the balancing weight 4922, and after the well lid 1 is installed, the balancing weight 4922 synchronously abuts against the well bottom position of the sewage well 00;
the third step: when the well cover 1 is installed in the initial stage, the photovoltaic power generation of the photovoltaic panel 10 is low, at this time, the collected power is supplied to the pressure sensor 43 in advance through the control of the control box 7, no power is supplied to the electromagnet 483, at this time, under the action of the buoyancy ball 4821, the buoyancy frame 482 floats on the whole above the liquid level of the sewage, due to the common buoyancy of the buoyancy frame 482 and the buoyancy rod 48 in the liquid level, the top end of the buoyancy rod 48 abuts against the abutting block 411 and supplies a continuous upward pushing force to the abutting block 411, the pushing force applied to the abutting block 411 is further applied to the monitoring ring 410, the monitoring seat 47 is further abutted against the pressure sensor 43 through the power connection between the monitoring ring 410 and the monitoring rod 46, and then, the pressure value transmitted by the pressure sensor 43 at this time is collected and converted through the control box 7, and compared with the previously measured sewage liquid level value, taking the pressure value at the moment as an initial value of measurement, after the value measurement record is finished, supplying power to the electromagnet 483 through the control box 7, and enabling the electromagnet 483 to generate magnetic force and be adsorbed on the buoyancy rod 48 after being electrified;
the fourth step: on the premise that the liquid level does not change, the pressure value received by the pressure sensor 43 is still the initial value, then, as time goes on and the external environment changes, when the liquid level in the bilge well 00 drops, the buoyancy frame 482 drops along with the drop of the liquid level, because the buoyancy frame 482 is adsorbed on the buoyancy rod 48 at this time, the buoyancy rod 48 is further pulled to synchronously slide downwards on the first slide rod 491, and in the process of dropping displacement, the abutting action on the abutting block 411 is gradually relieved, the pressure value applied to the pressure sensor 43 by the monitoring seat 47 is further reduced, at this time, the control box 7 only records and processes data, and does not give an alarm to the outside, when the liquid level in the bilge well 00 rises, because the buoyancy frame 482 and the buoyancy rod 48 are in a fixed connection state at this time, and the upper end of the buoyancy rod 48 at this time is abutted and limited by the abutting block 411, the buoyancy frame 482 does not rise with the rise of the liquid level;

and a sixth step: as can be seen from the buoyancy formula F-float = ρ liquid gV row, when the liquid level further rises and reaches the position of the air bag 484, as the air bag 484 is gradually submerged, the buoyancy value received by the buoyancy rod 48 is greatly changed compared with the case where the single buoyancy frame 482 is submerged, the pressure value received by the pressure sensor 43 is further caused to jump and change, and then, in the process of recording the jump and change of the data by the control box 7, since the bottom heights of the lowest set of air bags 484 and the sewage well 00 and the liquid level in the well are fixed values after the well lid 1 is completely installed, the jump and change of the pressure data at this time are recorded, the judgment basis of the rising distance of the liquid level from the initial position can be further used, since a plurality of sets of air bags 484 are installed in the vertical direction on the buoyancy rod 48, the number of sets of air bags in which the liquid level is not passed at this time can be further judged by recording the number of times of data jump and change, when the number of times of data jumping changes is consistent with the number of groups of the air bags 484, the fact that the height of the liquid level in the well at the moment reaches the height of the early warning water level is proved, and then an alarm is sent to the outside through the control box 7 to remind a worker to timely perform flood control and drainage operation.
The seventh step: in the daily use process, the flow monitor 37 and the guide rod 36 are in a relatively static state, the flow monitor 37 does not generate an electric signal, when rainy seasons come, partial rainfall and surface accumulated water can flow into the sewage well 00 through the water permeable holes 2, and further enter the inner side of the water filtering funnel 33 in the process that the rainwater flows downwards through the water permeable holes 2, when the rainwater flow reaches a certain volume and flow speed, the fan blade in the flow monitor 37 is impacted by the rainwater to start rotating on the guide rod 36, the induction coil in the flow monitor is further driven to rotate around the induction slice, according to the electromagnetic induction effect, the induction slice performs magnetic induction line cutting operation and generates alternating current, the value of the alternating current can generate corresponding change along with the rotation speed of the fan blade, when the rainfall increases, the rotation speed of the fan blade increases, the induction current generated by the induction slice correspondingly increases, the current change size of this moment through control box 7 record and compare its pressure variation numerical value of collecting on with pressure sensor 43, can further judge the source of well discharge, and can provide the filter action of certain degree for permeating water hole 2 through the striker rod 34 of circumference setting, the inflow of avoiding rubbish in the surrounding environment to cross the bush fallen leaves causes the jam of permeating water hole 2, and then influence the drainage effect of well lid 1 self, the vibrating spring 32 of setting can make drainage funnel 33 and striker rod 34 carry out self vibration when receiving external pressure, further promote the ejecting effect of the discharge to 2 outside region spots of permeating water hole.
