the following describes how the device works in various states of light rain and heavy rain;
when the rain is light for a long time, namely when the water inlet quantity of the water inlet 9 on the drum 2 is less than or equal to the water outlet quantity of the overflow hole on the fixed block, the rain is set to be in a light rain state; rainwater flows into the drum 2 through the water inlet pipeline 8, and the baffle 7 is in an inclined downward state, so that the rainwater can flow into the water collecting cavity 21 through the liquid inlet 20, the volume of the water collecting cavity 21 is smaller, and the water collecting cavity 21 can be quickly filled with the rainwater;
meanwhile, when water exists in the water collecting cavity 21, timing is started, that is, the water in the water collecting cavity 21 flows into the water collecting tank 13 through the capillary flow guide pipe 23, and here, when the water in the water collecting cavity 11 flows into the water collecting tank 30, the whole volume of the water collecting cavity 11 flows into the water collecting tank 30, so as to play a timing role, and for convenience of subsequent description, a device formed by the water collecting cavity 21 and the capillary flow guide pipe 23 is named as a timing device;
it is worth noting that the process that water in the water collecting cavity 21 flows into the water collecting tank 13 through the capillary draft tube 23 is very slow, the water flowing into the draft tube flows into the water collecting tank 13 through the liquid outlet tank, and as the vertical plate 31 is in a state of being vertically fixed by the overload device, rainwater can gradually gather in the cavity of the water collecting tank 13 on the right side of the vertical plate 31, the water in the water collecting tank 13 gradually increases, the pressure on the vertical plate 31 gradually increases, when the volume of the water gathered in the water collecting tank 13 is equal to the volume of the water collecting cavity 21, the pressure of the water can push the vertical plate 31 to rotate anticlockwise across the overload device, the water in the water collecting tank 13 can flow into the rainwater discarding cavity 5 through the water outlet tank 32, a timing cycle is completed, and as no rainwater exists at the water outlet 11, the water retaining plate 12 is not opened at this time; it should be noted that the purpose of timing during the light rain is to prevent the rainwater above the baffle 7 from penetrating into the drum 2 below the baffle 7 during the long-time light rain, and to avoid the situation that the flow rate is inaccurate due to the residual water originally contained in the drum 2 when the heavy rain occurs next time; when water permeates into the barrel 2 in a light rain state, the fixing device still loosens the water baffle 12 after a certain time, the water baffle 12 is rotated by the permeated water, the water outlet 11 is opened, and the permeated residual water is discharged, so that the flow of the water is more accurate next time.
In summary, in case of light rain, the rain water is discharged through the overflow hole, and a small amount of rain water is also discharged from the liquid outlet 15.
When the rain changes from light rain to heavy rain or the rain just starts to be heavy rain, namely when the water inflow of the water inlet 9 on the drum 2 is greater than the water outflow of the overflow hole on the fixed block, the state is set to be heavy rain;
rainwater flows into the barrel 2 through the water inlet 9, rainwater entering the barrel 2 enters the water collecting cavity 21 and rapidly fills the water collecting cavity 21, the rainwater can be gathered in the barrel 2, the baffle 7 rotates clockwise due to the rainwater in the barrel 2, when the baffle 7 rotates clockwise under the action of water pressure, the torsion spring at the baffle 7 is subjected to torsional deformation, when the baffle 7 drives the sleeve 16 to rotate, the sleeve 16 drives the first positioning pin 18 to rotate together, at the moment, the pressure spring at the first positioning pin 18 is in a compressed state, when the baffle 7 rotates through the water outlet 11 due to the water pressure in the barrel 2, the first positioning pin 18 rotates to be opposite to the first blind hole 17, the first positioning pin 18 moves into the first blind hole 17 under the pressure of the pressure spring, at the moment, the position of the baffle 7 is fixed, at the moment, the baffle 7 is subjected to the action of resultant force of the water pressure and the torsion spring, the application directions of the baffle 7 are opposite, the torsion force of the torsion spring is not enough to move the first positioning pin 18 out of the first blind hole 17; the water in the barrel 2 is fully collected to a certain amount, and the amount is the abandon flow;
meanwhile, in the process that the baffle 7 rotates clockwise, the baffle 7 rotates clockwise to drive the arc plate 10 to rotate through the fixing rod 26, the pressure spring at the arc plate 10 is compressed, the arc plate 10 rotates to enable the through groove 24 to be staggered with the water inlet 9, and the arc baffle 28 shields the water inlet 9 to enable the water inlet 9 to be closed; after the water inlet 9 is closed, rainwater flows into the rainwater treatment chamber 4 through the water inlet pipeline 8; meanwhile, in the rotating process of the baffle 7, the baffle 7 can drive the arc-shaped baffle 28 to rotate together, the through hole 29 is staggered with the liquid inlet 20, rainwater in the drum 2 cannot flow into the water collecting cavity 21 under the shielding of the arc-shaped baffle 28, and the water collecting cavity 21 is isolated from the drum 2;
the device starts timing when water exists in the drum 2, namely, the water in the water collecting cavity 21 flows into the water collecting tank 13 through the capillary flow guide pipe 23, and is worth noting that the process is very slow, the water flowing into the flow guide groove flows into the water collecting tank 13 through the liquid outlet groove, as the vertical plate 31 is in a state of being vertically fixed by the overload device, rainwater can be gradually gathered in the cavity of the water collecting tank 13 on the right side of the vertical plate 31, the water in the water collecting tank 13 is gradually increased, the pressure on the vertical plate 31 is gradually increased, when the volume of the water gathered in the water collecting tank 13 is equal to the volume of the water collecting cavity 21, the pressure of the water can push the vertical plate 31 to cross the overload device to rotate anticlockwise, the water in the water collecting tank 13 can flow into the rainwater discarding cavity 5 through the liquid outlet groove 32, and a timing period is completed;
the vertical plate 31 rotates anticlockwise to be separated from the water baffle 12, and at the moment, the barrel 2 at the position of the water baffle 12 is filled with rainwater, so that the rainwater can enable the water baffle 12 to rotate in the process, the torsion spring at the position of the water baffle 12 is subjected to torsional deformation, the water outlet 11 is opened, and the flow is abandoned, and it needs to be noted that in the process that the water outlet 11 is opened, the rainwater in the barrel 2 can fall onto the vertical plate 31 to form pressure on the vertical plate 31, so that the vertical plate 31 cannot be reversely rotated and reset, meanwhile, after the water flow in the barrel 2 is finished, the water pressure borne by the baffle 7 disappears, and under the action of the torsion spring torsion force, the baffle 7 reversely rotates to enable the first positioning pin 18 to move out of the first blind hole 17, and the baffle 7 reversely rotates and resets; after the rivers in cask 2 are accomplished, the pressure that breakwater 12 received disappears, and the contrarotation resets, and simultaneously under torsional spring torsion effect, riser 31 contrarotation resets, and the dowel is located positioning groove 38 again, and the position of riser 31 is fixed once more, and simultaneously, breakwater 12 is fixed by riser 31.
In conclusion, in heavy rain, under the timing action of the timing device, after a certain time, the liquid outlet groove is opened, and rainwater is discharged through the liquid outlet groove;
it is worth noting that when the device is used, if the timing device counts time, intermittent heavy rain does not repeatedly abandon the flow, the utilization rate of the rain can be increased, and: the purpose of discharging the large rain and the small rain is that when the small rain occurs, the garbage on the ground is not easy to flush, so that the whole small rain state is abandoned, when the large rain occurs, the garbage on the ground is easy to flush, and enters the abandoning device, so that when the large rain occurs, the liquid outlet groove with larger size is opened, the garbage is convenient to discharge, and the abandoning device is not blocked.
The timing device is matched with the overflow holes, so that rainwater can be directly discharged in light rain, unclean water is prevented from entering the sewage treatment device to increase the treatment strength of the sewage treatment device, and the filter screen is arranged at the timing device to retain impurities in the barrel 2 to prevent the impurities from blocking the timing device.
According to the invention, the baffle 7 and the arc-shaped plate 10 are arranged, so that when heavy rain occurs, after the rainwater amount in the drum 2 reaches the abandon flow rate, the arc-shaped plate 10 closes the water inlet 9, subsequent rainwater can enter the rainwater treatment chamber 4, the subsequent rainwater is treated by the rainwater treatment device, and after a certain time, the fixing device loosens the water baffle 12, the water baffle 12 rotates under the action of the gravity of the water to open the water outlet 11, the initial rainwater in the drum 2 is abandoned, and garbage in the drum 2 is discharged through the water outlet 11, so that the whole device is prevented from being blocked.
By the aid of the fixing device and the timing device, flow discarding can be performed only once in the timing time of the timing device if heavy rain with the property of rain fall occurs, and multiple flow discarding is not needed, so that the utilization rate of rainwater is increased.
According to the invention, the baffle 7 and the water outlet 11 with larger size are arranged, so that the inner wall of the barrel 2 can be scraped and cleaned in the rotation process of the baffle 7 in heavy rain, and finally the garbage is discharged from the water outlet 11, so that the situation that the garbage is accumulated in the barrel 2 for a long time and blocks the barrel 2 to lose the flow discarding effect is prevented, and the device automatically discards the flow after a certain time, automatically resets after the flow discarding, prepares for next flow discarding without manual operation, and has strong practicability.
The invention has novel concept, smart structure and strong practicability, can realize direct flow abandoning of small rain and one-time flow abandoning of large rain and time-interval rain gusts, has the self anti-blocking function and can always ensure the effectiveness of the flow abandoning device.
