[0049] Please refer to Figures 1 to 12The adjustable rain and sewage shunting and discharging device provided by the application will be described below. The adjustable rain and sewage shunting and discharging device comprises a shunting box 1 and a water storage box 2.

[0050] The shunting box 1 is used to be fixed on a horizontal plane and has a hollow structure with an opening facing upwards for rainwater to flow in. A partition plate 3 is arranged in the shunting box 1, and the outer periphery of the partition plate 3 is attached to the inner periphery of the shunting box 1 through a sealing ring to divide the space in the shunting box 1 into an upper space and a lower space.

[0051] The shunting box 1 is connected with an inlet pipe 11 and a sewage discharge pipe 12 which are in communication with the lower space and are used for sewage to flow through. In actual use, the sewage can be discharged in a targeted manner by connecting the inlet pipe 11 with a sewage discharge pipeline and connecting the sewage discharge pipe 12 with a sewage pipe, and the lower space can provide a temporary storage space for the sewage. In addition, the shunting box 1 is also connected with a water distribution pipe 13 which is in communication with the upper space and is used for rainwater to flow through, and the water distribution pipe 13 is connected with a rainwater discharge pipe 131 extending upwards.

[0052] It should be noted that the communication position of the water distribution pipe 13 and the shunting box 1 has a certain distance from the inner bottom surface of the upper space (i.e. the upper surface of the partition plate 3), so that part of the rainwater can be temporarily stored in the upper space after falling into the shunting box 1, thereby avoiding backflow and overflow caused by the inability of the fluid to gather in the shunting box 1. In addition, the rainwater discharge pipe 131 is used to be in communication with a rainwater pipe to realize the targeted discharge of rainwater to the rainwater pipe.

[0053] The water storage box 2 is used to be fixed on a horizontal plane outside the shunting box 1, as shown in Figs. Figure 1 and Figure 3 The water storage box 2 is supported on the horizontal plane through a supporting leg to keep the lower surface of the water storage box 2 at a certain distance from the horizontal plane.

[0054] The water storage box 2 is connected with a water discharge pipe 21 for rainwater to flow through, and the water discharge pipe 21 is located at the lower side of the water storage box 2 to ensure that the rainwater in the water storage box 2 is completely discharged. The water discharge pipe 21 is connected with a valve body 211, and the opening or closure of the water discharge pipe 21 can be controlled by controlling the valve body 211.

[0055] The water storage tank 2 is fixedly connected with a drainage pipe 22 in communication with the interior of the water storage tank 2, the drainage pipe 22 is in communication with the extended end of the water distribution pipe 13, and the drainage pipe 22 is provided with a water outlet 221 in communication with the interior of the water storage tank 2, in this embodiment, the water outlet 221 is downwardly arranged (to avoid the case of backflow of liquid) and is connected with a corresponding pipe body to realize directional discharge of liquid. In addition, the water storage tank 2 is further provided with a water blocking member 4 for closing the water outlet 221, so that the liquid entering the drainage pipe 22 cannot be discharged and finally returns to the water distribution pipe 13 and is discharged into the rainwater pipe through the rain discharge pipe 131.

[0056] In this embodiment, the partition plate 3 can divide the space in the shunt tank 1 into an upper space and a lower space; the upper space and the lower space do not exchange matters, so that the case that impurities in sewage affect rainwater is avoided. After the sewage enters the lower space through the sewage inlet pipe 11, the lower space can store a certain amount of sewage, and finally the sewage is discharged into the sewage pipe through the sewage discharge pipe 12; at the same time, when the rainwater enters the upper space through the opening in the upper part of the shunt tank 1, the rainwater gradually accumulates and is discharged into the water distribution pipe 13, and then is discharged into the rainwater pipe through the rain discharge pipe 131. When the rainfall is large, the water outlet 221 is opened by the water blocking member 4, so that the rainwater originally entering the rain discharge pipe 131 is adjusted to be discharged into the water storage tank 2 through the water outlet 221, to realize storage of part of the rainwater; when the stored rainwater needs to be used, the rainwater can be discharged in a directional manner by controlling the valve body 211 and the drain pipe 21.

[0057] Compared with the prior art, the adjustable rainwater and sewage shunt discharge device provided in this embodiment can realize regional discharge of rainwater and sewage, can ensure that the rainwater shunt space meets different rainfall requirements, and can improve the stability of the shunt discharge process.

[0058] In some embodiments, as shown in Figure 10 and Figure 11 The water blocking member 4 includes a water blocking plug 41 and a first linear cylinder 42.

[0059] The water blocking plug 41 is slidingly arranged in the drainage pipe 22 along the length direction of the drainage pipe 22, and the outer peripheral surface of the water blocking plug 41 is attached to the inner peripheral surface of the drainage pipe 22; in actual use, the water blocking plug 41 is suitable to be moved to a position for closing or avoiding the water outlet 221. In order to realize control of the movement of the water blocking plug 41, the water blocking plug 41 is provided with a transmission arm 411, the transmission arm 411 extends outwardly away from the water distribution pipe 13 to protrude out of the drainage pipe 22 and into the water storage tank 2.

[0060] The first linear cylinder 42 is arranged in the water storage tank 2 and fixedly connected with the drainage pipe 22, specifically fixed to the upper side of the drainage pipe 22 to avoid the influence of the liquid surface on the normal use. Based on this, the power output direction of the first linear cylinder 42 is parallel to the length direction of the drainage pipe 22, and the power output end is connected with the extending end of the transmission arm 411 to realize the driving of the transmission arm 411 in the drainage pipe 22.

[0061] In some embodiments, as shown in Figure 3 , the water inlet 221 has a plurality of water inlets 221, and the plurality of water inlets 221 are arranged at intervals along the length direction of the drainage pipe 22.

[0062] By adopting the above technical scheme, when the first linear cylinder 42 drives the water plug 41 to move, the water plug 41 can avoid the water inlet 221 or close one or more water inlets 221 to adjust the efficiency of rainwater flowing into the water storage tank 2, so that the rainwater can quickly flow into the water storage tank 2, and the stability of the device in use is improved.

[0063] In some embodiments, as shown in Figure 3 and Figure 12 , the water storage tank 2 has a support table 23.

[0064] The support table 23 is fixedly arranged on the inner bottom surface of the water storage tank 2 and supports the lower side of the drainage pipe 22 to avoid the bending phenomenon caused by excessive liquid in the drainage pipe 22 and improve the structural stability of the device.

[0065] In some embodiments, as shown in Figure 3 and Figure 8 , the shunt box 1 has a flow limiting assembly 5 for closing the water distribution pipe 13. The flow limiting assembly 5 can completely close, partially close, or not close the water distribution pipe 13 to match different situations of the device in use.

[0066] Based on this, the flow limiting assembly 5 includes a lifting block 51 and a second linear cylinder 52.

[0067] The lifting block 51 is slidably arranged on the inner side of the upper space in the up-down direction, and the outer side thereof is attached to the side where the water distribution pipe 13 is located, so as to be adapted to move to a position closing or avoiding the entrance of the water distribution pipe 13.

[0068] The second linear cylinder 52 is fixedly arranged in the shunt box 1 and drivingly connected with the lifting block 51 to drive the lifting block 51 to move in the up-down direction.

[0070] Correspondingly, in order to avoid liquid flowing in, the upper side of the mounting base 6 is further detachably connected with a baffle plate adapted to close the accommodating groove 61 and to allow the power output shaft of the second linear cylinder 52 to extend out.

[0071] Based on the foregoing, the partition plate 3 has a reserved hole 31 for the power output shaft of the second linear cylinder 52 to pass through, and a sealing sleeve 32 adapted to be sleeved on the outer periphery of the power output shaft of the second linear cylinder 52 is embeddedly connected in the reserved hole 31, so as to avoid rainwater entering the lower space through the gap between the reserved hole 31 and the power output shaft of the second linear cylinder 52.

[0072] In some embodiments, as shown in Figure 3 , Figure 5 and Figure 9 , the inner bottom surface of the flow divider 1 has an upwardly extending connecting rod 14, and the lower side of the mounting base 6 has a slot 62 adapted for the connecting rod 14 to be inserted; through the cooperation of the connecting rod 14 and the slot 62, the positioning and mounting of the mounting base 6 relative to the flow divider 1 can be achieved, and the mounting base 6 is fixed relative to the flow divider 1 in the horizontal direction.

[0073] In some embodiments, as shown in Figure 7 and Figure 8 , the lifting block 51 has a positioning hole 511 extending through in the up-down direction. Correspondingly, the power output end of the second linear cylinder 52 is adapted to abut against the lower side of the lifting block 51 and close the positioning hole 511, and the power output end of the second linear cylinder 52 is coaxially connected with a positioning screw 521 adapted to pass through the positioning hole 511 and extend out, and the extending end of the positioning screw 521 is threadedly connected with a anti-loosening nut 522 adapted to abut against the upper side of the lifting block 51.

[0074] Correspondingly, in order to avoid liquid flowing in, a sinking groove coaxially communicating with the positioning hole 511 is further provided on the upper side of the lifting block 51; when the anti-loosening nut 522 is connected with the positioning screw 521, the anti-loosening nut 522 is embeddedly arranged in the sinking groove. At the same time, a water-blocking cover is embeddedly connected at the opening of the sinking groove, so as to avoid liquid flowing in and affecting the threaded connection relationship between the anti-loosening nut 522 and the positioning screw 521.

[0075] Through the cooperation of the anti-loosening nut 522 and the power output end of the second linear cylinder 52, the detachable connection of the lifting block 51 and the second linear cylinder 52 can be achieved. In actual use, by detaching the lifting block 51 and the second linear cylinder 52, the partition plate 3 can be moved upwardly out of the flow divider 1, so as to facilitate the maintenance, repair or replacement thereof.

[0076] In some embodiments, as shown in Figure 6 , the partition plate 3 further comprises a plurality of guide rods 33 and a filter screen 7.

[0077] The plurality of guide rods 33 are arranged on the upper side of the partition plate 3; based on this, the plurality of guide rods 33 are arranged in a circumferential direction of the partition plate 3, and the axial direction of each guide rod 33 is parallel to the up-down direction, and the lower end of each guide rod 33 is fixedly connected to the upper side of the partition plate 3, and a welding method is usually selected for connection.

[0078] The filter screen 7 is arranged on the upper side of the guide rod 33, and the lower side of the filter screen 7 has a plurality of mounting sleeves 71 corresponding to the upper ends of the plurality of guide rods 33, so as to avoid movement of the filter screen 7 relative to the partition plate 3 in the horizontal direction, and to avoid deformation of the filter screen 7 itself.

[0079] Among them, the lifting block 51 is slidably connected with at least one guide rod 33 in the up-down direction, so as to limit the movement path of the lifting block 51 and ensure the structural stability of the device.
