Before the device is used, the drum 2 is positioned at the uppermost end of the displacement, the first positioning pin 16 is positioned in the first blind hole 17, the tension spring is in the original length, the drum 2 is fixed by the first positioning pin 16, the conical block 5 does not seal the water inlet 4, the baffle 20 is positioned in a state of inclining downwards rightwards, the water outlet 22 of the drum 2 is opposite to the water inlet 23 of the fixed block 10, and the water baffle 9 is positioned in the liquid outlet groove 8 and is fixed by the fixing device;
the following describes how the device works in various states of light rain and heavy rain;
when the rain is raining for a long time, namely when the water inlet quantity of the water inlet 4 on the drum 2 is less than or equal to the water outlet quantity of the overflow port 12 on the fixed block 10, the rain is set to be in a raining state; when the drum 2 is positioned at the uppermost position of the displacement, the conical block 5 is not positioned in the water inlet 4, the water inlet 4 is communicated with the cavity in the drum 2, and due to the action of the stop 21 of the drum 2, the stop 21 enables the right side baffle 20 to incline to the right and downwards at the moment, and the right side baffle 20 is positioned below the water outlet 22, so that rainwater flows into the baffle 20 of the drum 2 through the water inlet 4 and flows into the water collecting cavity 11 through the water outlet 22 at the moment, the volume of the water collecting cavity 11 is small, the rainwater can quickly fill the water collecting cavity 11, and at the moment, when the water inflow of the water inlet 4 on the drum 2 is less than or equal to the water outflow of the overflow port 12 on the fixed block 10, the rainwater cannot be collected in the drum 2, and the rainwater passes through the drum 2 and the water collecting cavity 11 and is discharged into the rainwater drainage chamber 7 from the overflow port 12;
meanwhile, the water in the water collecting cavity 11 flows into the water collecting tank 30 through the capillary flow guide pipe 13, the timing is started, and the time used when the water in the water collecting cavity 11 completely flows into the water collecting tank 30 is regarded as a timing period, and for convenience of describing the using process of the invention, a device formed by the water collecting cavity 11 and the flow guide pipe 13 is named as a timing device; it should be noted that the diameter of the capillary flow guiding pipe 13 is extremely small, so the process is very slow, the gravity of the water collecting tank 30 can be gradually increased by the water flowing into the water collecting tank 30, when the water in the volume of one water collecting cavity 11 in the water collecting cavity 11 completely flows into the water collecting tank 30, the water collecting tank 30 pulls the positioning rod 29 to move downwards under the action of the gravity, the tension spring is stretched, the positioning rod 29 moves downwards to drive the third positioning pin 32 to move downwards so that the third positioning pin 32 moves towards the direction far away from the third positioning blind hole 33, the pressure spring at the third positioning pin 32 is compressed, the third positioning pin 32 moves out of the third positioning blind hole 33, when the third positioning pin 32 is separated from the water baffle 9, the third positioning pin 32 resets under the pressure of the pressure spring, in the process, the purpose of the abdicating groove is to not block the sliding of the third positioning pin 32 and the up-down movement of the third positioning pin 32 along with the positioning rod 29, after the third positioning pin 32 moves out of the third positioning blind hole 33, the position of the water baffle 9 is released, and after the water baffle 9 is released, the liquid outlet tank 8 is not opened in the process because no rainwater exists in the barrel 2 at the position of the water baffle 9;
the main points of attention are: the purpose of loosening the water baffle 9 in the light rain process is to prevent rainwater above the baffle 20 from penetrating into the barrel 2 below the baffle 20 when the light rain is in a long time, and avoid the situation that the flow rate is inaccurate due to residual water originally contained in the barrel 2 when the heavy rain is in the next time; when water permeates into the barrel 2 in a light rain state, the fixing device still loosens the water baffle 9 after a certain time, the permeated water enables the water baffle 9 to rotate, the liquid outlet groove 8 is opened, and permeated residual water is discharged, so that the next flow metering is more accurate;
after the water collecting tank 30 moves downwards, the baffle cover 31 is pushed to rotate under the action of the ejector rod 34, the water outlet of the water collecting tank 30 is opened, and water in the water collecting tank 30 flows into the rainwater drainage chamber 7; when water in the water collecting tank 30 is discharged, the positioning rod 29 and the water collecting tank 30 move upwards to reset under the action of tension of the tension spring, in the process that the water collecting tank 30 resets upwards, the spherical surface of the third positioning pin 32 contacts with the water baffle 9 firstly, the water baffle 9 pushes the third positioning pin 32 to move towards the direction far away from the liquid outlet groove 8, when the water collecting tank 30 moves to the position that the third positioning pin 32 is opposite to the third positioning blind hole 33, the third positioning pin 32 moves into the third positioning blind hole 33 under the action of the pressure spring, and the position of the water baffle 9 is fixed again.
In summary, in case of light rain, the rain water is discharged through the overflow port 12, and a small amount of the rain water is also discharged from the opening of the water collecting tank 30.
When the rain is changed into heavy rain or the rain is just heavy rain, the rain water flows into the barrel 2 through the water inlet 4, the rain water entering the barrel 2 enters the water collecting cavity 11 in the fixed block 10 through the water outlet 22 and quickly fills the water collecting cavity 11, when the water inlet amount of the water inlet 4 on the barrel 2 is larger than the water outlet amount of the overflow port 12 on the fixed block 10, the rain water is gathered in the barrel 2, the baffle 20 is rotated clockwise by the rain water in the barrel 2, when the baffle 20 is rotated clockwise under the action of the water pressure, the torsion spring at the baffle 20 is twisted and deformed, the sleeve 19 drives the second positioning pin 25 to rotate together when the baffle 20 drives the sleeve 19 to rotate, at the moment, the pressure spring at the second positioning pin 25 is in a compressed state, when the baffle 20 rotates through the liquid outlet groove 8 under the water pressure in the barrel 2, the second positioning pin 25 rotates to be opposite to the second blind hole 24, and the second positioning pin 25 moves into the second blind hole 24 under the action of the pressure spring, at the moment, the position of the baffle 20 is fixed, the baffle 20 is subjected to the resultant force action of water pressure and a torsion spring, the force application directions of the baffle 20 and the water pressure and the torsion spring are opposite, the torsion force of the torsion spring is not enough to enable the second positioning pin 25 to move out of the second blind hole 24, when the water in the drum 2 is fully collected to a certain amount, the amount is to achieve the abandon flow rate, the drum 2 breaks through an overload device, the drum 2 can move downwards under the action of gravity, after the drum 2 moves downwards, the conical block 5 is positioned in the water inlet 4, rainwater flows into the box body 1 on the left side of the conical block 5 through the water inlet pipeline 3, meanwhile, the drum 2 moves downwards to enable the water inlet 23 to be separated from the water outlet 22, and water in the drum 2 cannot enter the water collecting cavity 11;
when raining, water in the water collecting cavity 11 flows to the water collecting tank 30 through the capillary flow guide pipe 13, and similarly, the gravity of the water collecting tank 30 is gradually increased by the water flowing into the water collecting tank 30, and similarly, when the water in the volume of one water collecting cavity 11 in the water collecting cavity 11 completely flows into the water collecting tank 30, the gravity of the water collecting tank 30 drives the third positioning pin 32 to break through the third positioning blind hole 33, the water collecting tank 30 moves downwards, so that the water baffle 9 is loosened, and as the barrel 2 at the position of the water baffle 9 is filled with rainwater at the moment, the rainwater can rotate the water baffle 9 in the process, so that the liquid outlet groove 8 is opened for drainage;
the water collecting tank 30 moves downwards, the baffle cover 31 is pushed to rotate under the action of the mandril 34, the water outlet of the water collecting tank 30 is opened, the water in the water collecting tank 30 flows into the rainwater drainage chamber 7, when the water in the water collecting tank 30 is discharged, the positioning rod 29 and the water collecting tank 30 move upwards to reset under the tension of the tension spring, when the water in the drum 2 is discharged from the liquid outlet groove 8, under the action of torsional spring torsion, the water baffle 9 reversely rotates and resets, the water baffle 9 firstly contacts with the spherical surface of the third positioning pin 32 in the process of reversely rotating and resetting, the water baffle 9 pushes the third positioning pin 32 to move towards the direction far away from the liquid outlet groove 8, the water baffle 9 rotates until the third positioning pin 32 is opposite to the third positioning blind hole 33, the third positioning pin 32 moves into the third positioning blind hole 33 under the action of the pressure spring, and the position of the water baffle 9 is fixed again.
In the rainwater drainage's of cask 2 in-process, cask 2 rebound resets, and simultaneously, after the rivers in cask 2 are accomplished, the water pressure that baffle 20 received disappears, and under the effect of torsional spring torsion, baffle 20 reverse rotation makes second locating pin 25 shift out second blind hole 24, and baffle 20 reverse rotation resets.
In conclusion, in heavy rain, when 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 for a time to play a role of timing, so that a timing device is formed, after a certain time, the liquid outlet groove 8 is opened, and rainwater is discharged through the liquid outlet groove 8;
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 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 when the large rain occurs, the liquid outlet groove 8 with larger size is opened, the garbage is convenient to discharge, and the abandoning device is not blocked.
The rainwater flow-discarding device can directly discard rainwater in light rain through the matching action of the overload device, the timing device and the overflow port 12, so that unclean water is prevented from entering the rainwater treatment device to increase the treatment strength of the rainwater 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, through the arrangement of the brush 35, the baffle 20 and the overload device, the barrel 2 breaks through the overload device and moves downwards when heavy rain falls, namely after the rain amount reaches the abandon flow rate, subsequent rain can enter the rain water treatment chamber 6, the subsequent rain water is treated by the rain water treatment device, and after a certain time, the rain water in the water collection cavity 11 enables the fixing device to loosen the water baffle 9, the water baffle 9 rotates under the action of the gravity of the rain water in the barrel 2, the initial rain water in the barrel 2 is abandoned, and the garbage in the barrel 2 is discharged through the liquid outlet groove 8, so that the blockage of the whole device is prevented.
By the cooperation of the overload device and the timing device, the invention can realize that the flow is abandoned once without a plurality of times when the timing device times out the time and the rain is heavy rain, thereby increasing the utilization rate of the rainwater.
According to the invention, the baffle 20 is arranged, the liquid outlet groove 8 with larger size can scrape and clean the inner wall of the barrel 2 in the rotation process of the baffle 20 in heavy rain, and finally the waste is discharged from the liquid outlet groove 8, so that the situation that the waste 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 stronger 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.
