The working principle of the movable rainwater storage box is as follows:

firstly, the movable rainwater storage box is moved to the position below an eave drainage pipe of a residential building, the eave drainage pipe is butted with a water inlet 22, rainwater drained from the roof of the residential building can enter the storage box 1, rainwater in the early stage of rainfall enters the filter barrel 2 through the water inlet 22, the rainwater is filtered by the inner wall of the filter barrel 2 and the permeable plate 48 positioned at the bottom of the filter barrel and then enters the transition bin 11, meanwhile, the motor 42 is started to drive the conveyor belt 43 to rotate, the fixture block 44 fixed on the conveyor belt 43 drives the first connecting rod 45 and the scraper 46 to move downwards along the rotating rod 4 until the permeable plate 48 descends to the bottom of the transition bin 11, the magnetic block 49 on the lower bottom surface of the permeable plate 48 and the magnetic strip 73 on the stirring rod 711 attract each other, the magnetic block 49, the magnetic strip 73 and the stirring rod 711 are 4 groups, and the connecting valve 7 is sucked from the position where the bottom of the transition bin 11 is communicated with the opening of the water, make in the transition bin 11 filtered rainwater enter into water storage bin 12, start to rotate motor 31 and make it drive dwang 4 rotatory to drive scraper blade 46 and strike off adnexed debris on 2 inner walls of filter vat, simultaneously permeable plate 48 passes through magnetic path 49 and drives puddler 711 and rotate, avoids silt to block up the entry.

At the moment, more heavy metal pollutants exist in the collected initial rainwater, the collected initial rainwater does not have recycling value, the initial rainwater and the later rainwater are judged according to the liquid level height monitored by the liquid level sensor 18, when the liquid level height in the water storage bin 12 reaches the height of the liquid level sensor 18, the liquid level sensor 18 transmits a signal to the controller 34, and the water outlet 15 is opened to discharge the water;

meanwhile, the rotating motor 31 stops rotating, the motor 42 rotates in the opposite direction, so that the conveyor belt 43 drives the fixture block 44 and the permeable plate 48 to move upwards along the rotating rod 4, the connecting valve 7 is separated from the permeable plate 48 under the separation of the baffle plate 74, so that the water blocking plug 72 falls down to block the inlet between the transition bin 11 and the water storage bin 12, the permeable plate 48 carries filtered and scraped impurities to move to the top of the filter barrel, the first connecting rod 45 stops moving when moving to the uppermost side and contacting with the pressure sensor 33 at the bottom of the motor set 3, the scraper 46 enters the opening 211, the motor 42 is closed, the pressure sensor 33 transmits a signal to the controller 34, the push rod motor 32 is controlled to be opened, the push rod motor 32 controls the telescopic rod 51 to retract and simultaneously drive the S-shaped pipe 5 to move towards the empty groove 23 of the filter barrel 2, the push plate 55 at the bottom of the S-shaped pipe 5 pushes the impurities, garbage and the like recovered on the permeable plate 48 from the empty groove 23 to the garbage, meanwhile, the first opening 53 of the S-shaped pipe 5 is in butt joint with the water inlet 22, and the second opening 54 of the S-shaped pipe 5 is in butt joint with the flow guide pipe 13, so that clean later-stage rainwater with a use value is directly collected into the water storage bin 12 through the flow guide pipe 13 and the filtering of the filter screen 16.

The collected rainwater is settled to settle the residual silt in the sand settling bin 14 after standing and settling, and when the rainwater is used, a water pipeline is connected to a water outlet 15 and the water outlet is opened, so that the rainwater storage tank can be moved to a place where water is needed for use.
