Figure 3 It is a structural schematic diagram of an initial rainwater abandonment device of an initial rainwater abandonment rainwater outlet of the present invention, Figure 4 FIG. 1 is a schematic structural diagram of a back plate of an initial rainwater discharge outlet of the present invention. Figure 1-4 As shown, a preferred embodiment of an initial rainwater abandonment rainwater outlet is shown, comprising: a well chamber 1 and an initial rainwater abandonment device 6, the top of the well chamber 1 has a wellhead 11, a rainwater grate 5 and a sewage interception hanging basket 4 located below the rainwater grate 5 are installed at the wellhead 11, the rainwater grate 5 is used to intercept larger garbage and prevent people from falling, and the sewage interception hanging basket 4 is used to intercept smaller garbage such as leaves and plastic bags carried in the initial rainwater, the bottom side wall of the well chamber 1 is connected with an initial rain abandonment pipe 8 and a rainwater connecting pipe 7, the initial rainwater abandonment device 6 is arranged in the well chamber 1, and is used to abandon the initial rainwater from the initial rain abandonment pipe 8 and the rainwater after the initial rain from the rainwater connecting pipe 7. The pipe 7 is used to collect rainwater; wherein, the initial rainwater discarding device 6 includes: a rotating shaft 63, a gate plate 61 and a handle 64. The rotating shaft 63 is rotatably arranged in the well chamber 1 and is located above between the initial rain discarding pipe 8 and the rainwater connecting pipe 7. The gate plate 61 is connected to the rotating shaft 63. The gate plate 61 has a through hole 611. One end of the handle 64 is connected to the rotating shaft 63, and the other end is connected to a float 65. When it rains for the first time, the float 65 droops to make the gate plate 61 block the rainwater connecting pipe 7. After the first rain, the float 65 floats up to make the gate plate 61 swing down, thereby making the gate plate 61 block the initial rain discarding pipe 8 and making the through hole 611 communicate with the rainwater connecting pipe 7.
[0031] In the present embodiment, when it rains for the first time, rainwater flows into the well chamber 1 and is discharged through the initial rain waste flow pipe 8. After the initial rain, as the amount of rainfall in the well chamber 1 increases, the float 65 floats upward under the buoyancy generated by the rainwater, and drives the lifting handle 64 to swing upward, while driving the rotating shaft 63 to rotate synchronously. At the same time, the gate plate 61 swings downward under the drive of the rotating shaft 63 until the gate plate 61 blocks the initial rain waste flow pipe 8 and the through hole 611 is connected to the rainwater connecting pipe 7. At this time, the rainwater is discharged and collected through the rainwater connecting pipe 7.
[0032] In this embodiment, the initial rainwater can be discarded through the initial rainwater discarding device 6. The initial rainwater discarding can effectively reduce the cost of subsequent rainwater resource utilization, avoid turbidity, eutrophication and water quality deterioration caused by direct discharge of initial rainwater into the water body, and reduce pollution to the water body and the environment.
[0033] In this embodiment, the initial rainwater discarding device 6 adopts non-powered operation, has the characteristics of simple structure and convenient maintenance, and can reduce the subsequent maintenance cost.
[0034] In this embodiment, the waste interception hanging basket 4 can intercept smaller garbage such as leaves and plastic bags carried in the initial rainwater, so as to prevent the garbage from clogging the initial rainwater discharge device and affecting the initial rainwater discharge effect.
[0035] More preferably, the sewage intercepting hanging basket 4 sinks downward to form an interception space, which can intercept and accommodate more smaller garbage, and the inner walls around the interception space are all inclined, and the inner walls around the interception space and the bottom inner wall have a number of interception holes. The inner walls around the interception space are inclined, which can concentrate the garbage at the bottom of the interception space. The inclined surfaces of the inner walls around the interception space have interception holes. When the garbage blocks the interception holes at the bottom of the interception space, rainwater can flow into the well chamber 1 through the interception holes on the inner walls around the interception space.

During the initial rain, the float 65 droops so that the gate plate 61 and the first limit plate 68 are limited and matched, and the gate plate 61 blocks the rainwater connecting pipe 7. After the initial rain, the float 65 floats up so that the handle 64 and the second limit block 67 are limited and matched, and the gate plate 61 blocks the initial rain abandonment pipe 8 and connects the through hole 611 with the rainwater connecting pipe 7.
[0037] Furthermore, as a preferred embodiment, the initial rainwater discharge device 6 also includes a back plate 62, which is connected to the inner wall of the well chamber 1 and has two holes 621, one of which is connected to the initial rain discharge pipe 8, and the other is connected to the rainwater connecting pipe 7. The rotating shaft 63 is rotatably arranged on the back plate 62. When it rains initially, the gate plate 61 blocks the hole 621 connected to the rainwater connecting pipe 7. After the initial rain, the gate plate 61 swings down and blocks the hole 621 connected to the initial rain discharge pipe 8, and makes the through hole 611 connected to the hole 621 connected to the rainwater connecting pipe 7.
[0038] Furthermore, as a preferred embodiment, in order to improve the sealing effect of the gate plate 61 on the hole 621 and to improve the sealing effect of the gate plate 61 on the initial rainwater discharge pipe 8 / rainwater connecting pipe 7, a sealing ring 66 is provided at each hole 621.
[0039] Furthermore, as a preferred embodiment, in order to reduce the weight of the gate plate 61, the gate plate 61 is hollow inside.
[0040] Furthermore, as a preferred embodiment, a bracket 3 is provided at the wellhead 11 , and the sewage interception hanging basket 4 and the rainwater grate 5 are both mounted on the bracket 3 .
[0041] Furthermore, as a preferred embodiment, the bottom of the well chamber 1 has a bottom plate 12 .
