[0026] As Figure 1 , Figure 2 shown, a preferred embodiment of the initial rainwater runoff and discard system of the present utility model includes:
[0027] The pool body 1, with a water inlet pipe 31 connected to one side of the pool body 1, and a water outlet 14 provided on the other side of the pool body 1;
[0028] The oil baffle 2, which is vertically or obliquely arranged in the pool body 1. The oil baffle 2 divides the pool cavity of the pool body 1 into a first cavity 11 and a second cavity 12, and a water guiding channel 13 for communicating the first cavity 11 and the second cavity 12 is provided between the lower end of the oil baffle 2 and the bottom of the pool body 1. The water inlet pipe 31 is communicated with the first cavity 11, and the water outlet 14 is communicated with the second cavity 12;
[0029] The first control valve 41, which is connected to the water inlet pipe 31;
[0030] The liquid level gauge, which is arranged in the pool body 1;
[0031] The controller, the liquid level gauge, and the first control valve 41 are all electrically connected to the controller.
[0032] Specifically, the water guiding channel 13 is located at the bottom of the first cavity 11 and the second cavity 12, enabling the first cavity 11 and the second cavity 12 to form a communicating vessel; the initial rainwater flows into the first cavity 11 through the water inlet pipe 31. When the rainwater flowing into the first cavity 11 from the water inlet pipe 31 reaches the set liquid level of the liquid level gauge, the first control valve 41 is closed through the controller, which can achieve the quantitative interception of the initial rainwater; the oil baffle 2 can block the oil floating on the upper part of the first cavity 11 from flowing into the second cavity 12, thereby preventing the oil from flowing into the water outlet 14 and avoiding the oil from flowing into the post-treatment device located downstream of the pool body 1; moreover, the lower part of the rainwater in the first cavity 11 is oil-free, and this oil-free part of the rainwater can flow from the first cavity 11 into the second cavity 12 through the water guiding channel 13, ensuring that the oil-free rainwater in the pool body 1 can smoothly flow into the second cavity 12 and through the water outlet 14 into the post-treatment device; therefore, the initial rainwater diversion system of the present utility model can quantitatively intercept the initial rainwater and remove oil from the intercepted initial rainwater.
[0033] Among them, as the lower layer of the rainwater in the first cavity gradually flows into the second cavity, if the rainwater in the first cavity drops below the highest point of the water guiding channel 13, the oil floating on the top layer of the rainwater in the first cavity can flow into the second cavity through the water guiding channel 13, which will increase the amount of oil flowing into the post-treatment equipment. To prevent the rainwater in the cavity from dropping below the highest point of the water guiding channel 13, in this embodiment, the water outlet 14 is arranged higher than the water guiding channel 13. In other embodiments of the present utility model, another liquid level gauge for monitoring the lowest point of the rainwater in the first cavity 11 can be provided in the first cavity 11. The lowest liquid level of the rainwater in the first cavity 11 is monitored through this liquid level gauge, and this lowest liquid level is higher than the highest point of the water guiding channel 13. When the liquid level of the rainwater in the first cavity 11 reaches the lowest liquid level, the water outlet 14 is closed.
[0034] In this embodiment, the oil baffle 2 is arranged vertically, and the oil baffle 2 is spaced up and down from the bottom of the pool body 1. The space between the oil baffle 2 and the bottom of the pool forms the water guiding channel 13. In other embodiments of the present utility model, the lower section of the oil baffle 2 can be abutted against the bottom of the pool, and an opening is provided at the lower end of the oil baffle 2, and this opening forms the water guiding channel 13.
[0035] After the single precipitation treatment is completed, a part of rainwater remains in the first cavity 11 and the second cavity 12. The liquid level of the remaining rainwater is higher than the highest point of the water guiding channel 13 and lower than the lowest point of the water outlet 14. In this embodiment, the pool body 1 is arranged underground, and the top of the pool body 1 is provided with a top cover. The setting of the top cover enables the utilization of the space above the pool body 1 and can slow down the speed of the rainwater remaining in the pool body 1 decreasing due to natural evaporation. Because if the rainwater in the pool body 1 completely dries up before the next rainfall, the liquid level of the rainwater in the pool body 1 will be lower than the water guiding channel 13 at the initial stage of rainwater collection. At this time, part of the oil liquid will flow into the second cavity 12; by setting an oil cleaning port 15 on the top cover, after the rainwater treatment is completed, the oil liquid on the upper layer of the rainwater remaining in the lower cavity is removed through the oil cleaning port 15.
[0036] Since the rainwater often contains impurities such as sediment, in this embodiment, a silt extraction port is provided at the bottom of the pool body 1, which is convenient for regularly cleaning the sediment and impurities deposited at the bottom of the pool body 1 and ensuring the smoothness of the water guiding channel 13.
[0037] For the convenience of silt extraction operation, in this embodiment, a second valve body is provided at the silt extraction port. The initial rainwater runoff system includes a silt extraction device, and the silt extraction device is communicated with the silt extraction port at the bottom of the pool body 1. When silt extraction is required, the valve body and the silt extraction device are opened to clean the sediment and impurities at the bottom of the pool. In this embodiment, the valve body is a control valve, and the control valve is electrically connected to the controller, which is convenient for the silt extraction operation.
[0038] In this embodiment, the initial rainwater runoff system includes an inlet main pipe 33, a drain pipe 32, a rainwater collection pipe network, and a second control valve 42 connected to the drain pipe 32. One end of the drain pipe 32 and the end of the water inlet pipe 31 far from the pool body 1 are both communicated with the inlet main pipe 33, and the other end of the drain pipe 32 is communicated with the rainwater collection pipe network. The second control valve 42 is electrically connected to the controller. Specifically, the inlet main pipe 33 has a slope, and the rainwater on the road surface flows into the inlet main pipe 33 through the higher end of the inlet main pipe 33. At the initial stage of rainfall, the first control valve 41 is opened and the second control valve 42 is closed through the controller, and the initial rainwater flows into the first cavity 11. As the rainfall progresses, the rainwater flow rate increases, and the liquid level of the rainwater in the first cavity 11 gradually rises to the set position of the liquid level gauge. At this time, the liquid level gauge sends an electrical signal to the controller, and the controller sends an electrical signal to the first control valve 41 to close the first control valve 41. At the same time, the controller sends an electrical signal to the second control valve 42 to open the second control valve 42, and the later rainwater flows into the rainwater collection pipe network through the drain pipe 32.
[0039] In this embodiment, the initial rainwater runoff system further includes a post-treatment device for treating the initial rainwater, and the post-treatment device is communicated with the water outlet 14. The post-treatment device can be a water treatment device such as a sedimentation tank, a biological decomposition tank, a filtration tank, etc.
[0040] In summary, the initial rainwater runoff diversion system of the present utility model includes a pool body 1, an oil baffle 2, a first control valve 41, a liquid level gauge and a controller disposed in the pool body 1. A water inlet pipe 31 is connected to one side of the pool body 1, and a water outlet 14 is provided on the other side of the pool body 1. The oil baffle 2 is vertically or obliquely disposed in the pool body 1. The oil baffle 2 divides the pool cavity of the pool body 1 into a first cavity 11 and a second cavity 12, and a water guiding channel 13 is provided between the lower end of the oil baffle 2 and the bottom of the pool body 1. The water guiding channel 13 is located at the bottom of the first cavity 11 and the second cavity 12, enabling the first cavity 11 and the second cavity 12 to form a communicating vessel. The initial rainwater flows into the first cavity 11 through the water inlet pipe 31. When the rainwater flowing into the first cavity 11 from the water inlet pipe 31 reaches the set liquid level of the liquid level gauge, the first control valve 41 is closed through the controller, enabling quantitative interception of the initial rainwater. The oil baffle 2 can block the oil floating on the upper part of the first cavity 11 from flowing into the second cavity 12, thereby preventing the oil from flowing into the water outlet 14 and preventing the oil from flowing into the post-treatment device located downstream of the pool body 1. Moreover, the lower part of the rainwater in the first cavity 11 does not contain oil, and this part of the oil-free rainwater can flow from the first cavity 11 into the second cavity 12 through the water guiding channel 13, ensuring that the oil-free rainwater in the pool body 1 can smoothly flow into the second cavity 12 and flow into the post-treatment device through the water outlet 14. Therefore, the initial rainwater runoff diversion system of the present utility model can quantitatively intercept the initial rainwater and remove oil from the intercepted initial rainwater.
[0041] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present utility model, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present utility model.
