It will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The technical solution of the present invention is further described with reference to the accompanying drawings and embodiments.

The rainwater well special for the sponge city as shown in the drawing comprises a well body 11, an outward-expanded water inlet cavity 12 is formed at the top of the well body 11, an installation cylinder 2 is sleeved in the well body 11, the installation cylinder 2 extends into the water inlet cavity 12, a first water inlet hole 2a communicated with the water inlet cavity 12 is formed in the side wall of the installation cylinder 2, the top of the installation cylinder 2 is detachably connected with a well cover 3, an installation hole and a water permeable hole 3a are formed in the well cover 3, a telescopic cylinder 41 is slidably connected in the installation hole, a second water inlet hole 41a is formed in the side wall of the telescopic cylinder 41, the top of the telescopic cylinder 41 is connected with an end cover 42, a water accumulating cup 5 is arranged inside the installation cylinder 2, an overflowing passage is formed between the side wall of the water accumulating cup 5 and the side wall of the installation cylinder 2, the projection of the water accumulating cup 5 on the well cover 3 covers the telescopic cylinder 41 and the water permeable hole 3a, the end cover 42 is connected with a floating body 43 extending into the water accumulating cup 5, a drain hole 5 is formed in the bottom of the water accumulating cup 5, and a drain hole 5a is formed in the bottom of the water accumulating cup 5, and the drain hole 3a maximum overflowing amount larger than the maximum amount of the water permeable hole 5 a. When the rainfall is low, the rainwater flowing to the rainwater well completely flows into the water inlet cavity 12, or the water inlet quantity of the water permeable hole 3a is smaller than the maximum overflowing quantity of the water drainage hole 5a, the water level in the water accumulation cup 5 is zero, and the telescopic cylinder 41 is positioned in the installation cylinder 2, so that the passing of pedestrians and vehicles is not obstructed; it can be understood that even if some rainwater flows into the water collecting cup 5 through the water permeable holes 3a, if the water inflow amount of the water permeable holes 3a is smaller than the maximum overflow amount of the water discharge holes 5a, the rainwater flowing into the water collecting cup 5 will flow away through the water discharge holes 5a rapidly, and the water level in the water collecting barrel will not rise. In a heavy rain day, the external water supply amount is larger than the maximum overflow amount of the first water inlet hole 2a, a part of rainwater flowing to the rainwater well can overflow the water inlet cavity 12 and then flows into the water accumulating cup 5 through the water permeable hole 3a, because the maximum overflow amount of the water permeable hole 3a is larger than the maximum overflow amount of the drain hole 5a, if the water inlet amount of the water permeable hole 3a is larger than the maximum overflow amount of the drain hole 5a, the water level in the water accumulating cup 5 can gradually rise, so that the floating body 43 drives the telescopic cylinder 41 to protrude from the top end of the well cover 3 under the action of buoyancy, the rainwater overflowing the water inlet cavity 12 can flow into the well body 11 through the second water inlet hole 41a, and the maximum water inlet amount of the rainwater well is increased. In addition, after the rainfall is reduced, the rainwater flowing to the rainwater well completely flows into the water inlet cavity 12, or the water inlet amount of the water permeable hole 3a is smaller than the maximum overflowing amount of the water drainage hole 5a, the water level in the water accumulation cup 5 is reduced, the telescopic cylinder 41 automatically slides downwards under the action of gravity, and the situation that the telescopic cylinder 41 still obstructs the passing of pedestrians and vehicles after the rainfall is reduced is avoided.

Preferably, the bottom of the mounting cylinder 2 is detachably connected with a flow guide hopper 6, the water accumulation cup 5 is integrally connected with the flow guide hopper 6, a filter barrel 71 is arranged below the flow guide hopper 6, the projection of the filter barrel 71 on the flow guide hopper 6 covers a small hole of the flow guide hopper 6, and the flow guide hopper 6 can guide rainwater falling from the mounting cylinder 2 to the filter cylinder, so that the rainwater falling from the mounting cylinder 2 is firstly filtered by the filter cylinder, and the rainwater guide hopper is favorable for preventing sundries of the rainwater from flowing into municipal sewage pipes through a rainwater well and causing the municipal sewage pipes to be blocked; the filter barrel 71 is detachably connected with the well body 11, and a manager can sequentially detach the well cover 3, the diversion hopper 6 and the filter barrel 71 from the rainwater well, so that the manager can conveniently clean the filter barrel 71; an overflow channel is formed between the filtering barrel 71 and the side wall of the well body 11, and if the filtering barrel 71 is seriously blocked, rainwater exceeding the capacity of the filtering barrel 71 can overflow to the overflow channel from the top end of the filtering barrel 71, so that the rainwater well can still normally drain water under the condition that the filtering barrel 71 is seriously blocked.

Preferably, a water storage cup 8 is arranged in the overflow channel, a flow guide groove 71a aligned with the water storage cup 8 is formed at the top of the filter barrel 71, and a blockage warning mechanism is arranged on the well cover 3 and linked with the water storage cup 8. Jam warning mechanism includes swing arm 91 with well lid 3 looks articulated, and swing arm 91 can be at vertical rotation in face, and the one end of swing arm 91 is connected with warning pole 92, and the other end of swing arm 91 is connected with water storage cup 8 through stay cord 93, is connected with elastic component 94 between swing arm 91 and the well lid 3, and in this embodiment, elastic component 94 is the shell fragment, and elastic component 94 makes swing arm 91 keep having the trend that drives warning pole 92 and hug closely well lid 3. If the filtering barrel 71 is not seriously blocked, rainwater in the filtering barrel 71 can be directly drained through the filtering holes of the filtering barrel 71, rainwater does not exist in the water storage cup 8, the self weight of the water storage cup 8 cannot overcome the elastic force of the elastic piece 94 to drive the swing arm 91 to rotate, and the warning rod 92 is tightly attached to the well lid 3 under the elastic force of the elastic piece 94; if the filtering barrel 71 is seriously blocked, a part of rainwater exceeding the capacity of the filtering barrel 71 flows into the water storage cup 8 through the diversion trench 71a, so that the weight of the water storage cup 8 is increased enough to overcome the elastic force of the elastic piece 94 to drive the swing arm 91 to rotate, and the warning rod 92 is erected to remind a manager to clean the filtering barrel 71 in time. A through hole for the pull rope 93 to pass through is formed in the flow guide hopper 6, one section of the pull rope 93, which is located below the flow guide hopper 6, is connected with an umbrella skirt 95, and the umbrella skirt 95 can prevent rainwater from flowing into the water storage cup 8 along the pull rope 93.
