[0002] In rainy weather, rainwater will carry some surface pollutants into the rainwater pipe network and finally into the drainage system. Considering that the pollutants in rainwater are mainly concentrated in the initial rainwater, some cities have built some storage ponds to solve the problem of initial rainwater pollution, but generally the costs are relatively high, and it is difficult to accurately collect the initial rainwater; there are also hanging basket type sewage intercepting rainwater grates, but the disadvantage of this type of rainwater grate is that it can only intercept larger garbage such as leaves and cannot intercept muddy water. If the grid is too dense, it will increase the risk of the rainwater grate being blocked and waterlogging. Content of the Utility Model

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] As a preferred embodiment of the present utility model, as Figures 1-3As shown in the figure, this embodiment provides a device for intercepting and removing pollutants from initial rainwater, which includes a rainwater diversion trough 1. A diversion pipe 2 is connected to the bottom of the rainwater diversion trough 1, and a pollution interception mechanism 3 is connected to the bottom of the diversion pipe 2. The pollution interception mechanism 3 includes a grid bucket 30. Leakage holes 31 are formed on the surface of the grid bucket 30. A filter bag 32 is arranged in the inner cavity of the grid bucket 30. A bucket cover 33 is sleeved on the top of the grid bucket 30. A sealing ball 34 is arranged in the inner cavity of the filter bag 32.

[0020] When the above-mentioned embodiment is implemented, by setting the grid bucket 30, the leakage holes 31 and the filter bag 32, the sewage flows into the inner cavity of the filter bag 32 through the rainwater diversion trough 1 and the diversion pipe 2, and the impurity sludge is collected to prevent the pipeline from being blocked by the discharge of impurity sludge. By setting the sealing ball 34, which floats on the water, it can block the top of the bucket cover 33 to prevent the impurities in the filter bag 32 from being discharged from the top.

[0021] In some embodiments, as Figure 1 shown, a telescopic hose 35 is connected to the surface of the bucket cover 33. The end of the telescopic hose 35 away from the bucket cover 33 is sleeved on the surface of the diversion pipe 2. By setting the telescopic hose 35, it is convenient to connect with the diversion pipe 2 to divert the sewage.

[0022] As Figure 2 shown, a hook 36 is fixedly connected to the inner wall of the grid bucket 30, and the filter bag 32 is hung on the surface of the hook 36. By setting the hook 36, the filter bag 32 is hung, which is convenient for the installation of the filter bag 32.

[0023] As Figure 2 shown, a clamping mechanism 4 is installed on the surface of the bucket cover 33. The clamping mechanism 4 includes a spring 40. One side of the spring 40 is fixedly connected to the grid bucket 30, and the other side of the spring 40 is fixedly connected to a connecting plate 41. A clamping block 42 is fixedly connected to the surface of the connecting plate 41. A clamping hole 43 is formed on the surface of the bucket cover 33. The side of the clamping block 42 away from the connecting plate 41 extends into the inner cavity of the clamping hole 43. By setting the spring 40, the connecting plate 41 is connected, so that the connecting plate 41 drives the clamping block 42 to be clamped with the clamping hole 43, thereby locking and fixing the bucket cover 33, improving the stability of the bucket cover 33.

[0024] As Figure 2As shown, a guide rod 44 is fixedly connected to the surface of the grid bucket 30. One end of the guide rod 44 away from the grid bucket 30 penetrates through the spring 40 and the connecting plate 41 respectively. A limiting block 45 is fixedly connected to one end of the guide rod 44. A pull rod 46 is fixedly connected to one side of the connecting plate 41. By providing the guide rod 44, the connecting plate 41 is guided to facilitate the movement of the connecting plate 41. By providing the limiting block 45, the lateral movement distance of the connecting plate 41 is limited to prevent the connecting plate 41 from separating from the guide rod 44. By providing the pull rod 46, it is convenient to pull the connecting plate 41 to move, so that the clamping block 42 is separated from the clamping hole 43, facilitating the disassembly of the bucket cover 33.

[0025] As Figure 1 As shown, a rainwater collection tank 5 is arranged outside the rainwater diversion trough 1. One side of the rainwater diversion trough 1 is connected to the rainwater collection tank 5 by bolts. A drain pipe 6 is communicated with one side of the rainwater collection tank 5. By providing the drain pipe 6, it is convenient to discharge the rainwater into the municipal drainage system.

[0026] In some embodiments, the rainwater diversion trough 1 is installed on the inner wall of the rainwater collection tank 5 by bolts. The rainwater diversion trough 1 and the pollution interception mechanism 3 are installed around the inner wall of the rainwater collection tank 5. The initial rainwater enters the rainwater diversion trough 1 through the rain grate, and then enters the filter bag 32 through the diversion pipe 2 and the telescopic hose 35. The rainwater passes through the filter bag 32 and the leakage holes 31, and finally is discharged through the drain pipe 6. The filter bag 32 is a water-permeable bag for filtering the main pollutants. The sealing ball 34 is a sphere that can float on the water surface and has a diameter larger than the diameter of the round hole at the top of the bucket cover 33. In rainy weather, as the water level in the filter bag 32 rises, the sealing ball 34 is floated accordingly; when the rainwater entering the filter bag 32 further increases, the sealing ball 34 moves upward to block the round hole at the top of the bucket cover 33; the remaining rainwater no longer enters the filter bag 32 and directly enters the rainwater collection tank 5 and is discharged through the drain pipe 6, which will not affect the water discharge efficiency.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
