The water storage device is characterized by further comprising a positioning ring 24, the positioning ring 24 is arranged on the guide rod 23 at an interval between the layering partition plate 13 and the layering partition plate 13, the floating plate 20 keeps an interval between the positioning ring 24 and the layering partition plate 13, so that the first water storage cavity 15 is communicated with the second water storage cavity 16 in an initial state, the interval between the balancing weight 22 and the floating plate 20 is larger than the interval between the positioning ring 24 and the layering partition plate 13, the balancing weight can be separated from the shunting port in a free state, and a shunting channel 25 is formed between the floating plate 20 and the layering partition plate 13;
in the state of no water flow in the sewage well 1, the floating plate 20 is supported on the positioning ring 24, and the balancing weight 22 is separated from the diversion port 14; under the condition that water flows in the sewage well 1, water solution continuously flows into the first water storage cavity 15 from the second water storage cavity 16 until sewage in the first water storage cavity 15 overflows into the second water storage cavity 16 and floats up the floating plate 20, and the balancing weight 22 blocks the branch port 14, so that the two water storage cavities are isolated. Liquid level in the first water storage chamber 15 risees gradually and spills over from diverging port 14 to second water storage chamber 16, has been the later stage rainwater this moment, and when the liquid level height in second water storage chamber 16 reached kickboard 20 department, kickboard 20 received the buoyancy effect of liquid level, and kickboard 20 rises and upwards follows up and drive balancing weight 22 along with the liquid level, and the interior aqueous solution of second water storage chamber 16 passes through drain pipe 2 to the collector tube drainage.

When the liquid level in the overflow area 18 is higher than the highest level of the drain pipe 2, the drain pipe generates a siphon phenomenon, the aqueous solution in the second water storage cavity 16 automatically flows from the drain water inlet end 2a to the drain water outlet end 2b and continuously flows into the confluence pipeline 3, the water outlet end of the confluence pipeline 3 is connected to a water collecting tank or a river channel for irrigation, and through the siphon action of the drain pipe 2, the aqueous solution can be effectively ensured to flow into the confluence pipeline 3, meanwhile, the input and use of power equipment such as a water pump and the like are reduced, and the cost input, the later maintenance and the like are greatly saved.
Wherein, under the state that said floating plate 20 floats and draws the clump weight 22 to block in the diversion port 14, the liquid level in said second water storage cavity 16 is higher than the peak of the drain pipe 2, namely exceed the turn-out 2c of the drain pipe 2, guarantee the siphonage, the said drainage water inlet end 2a locates between locating ring 24 and layered baffle 13, in order to guarantee the spontaneous process of the siphonage, lay under the ground, can use the use of the power equipment or reduce the power equipment effectively, reduce the cost by a wide margin, and guarantee when the liquid level is lower than certain degree, the clump weight 22 can be automatic and smooth to move downwards.
If the height of the drainage water inlet end 2a is higher than that of the positioning ring 24, when the rainwater stops and siphoning stops, the liquid level of the second water storage cavity 16 is higher than that of the positioning ring 24, the water solution still has certain buoyancy on the floating plate, the separation distance between the balancing weight 22 and the air flow port 14 is smaller, and meanwhile, the later-stage rainwater in the second water storage cavity is still more and cannot be fully discharged. If the height of drainage inlet end 2a is only less than the height of holding ring 24, and not siphon structure, though can guarantee that the aqueous solution passes through drain pipe 2 outflow in the second water storage chamber 16, but under the same pipe diameter state, the velocity of flow that its relative siphon action of velocity of flow produced is slow, can not be quick with the aqueous solution discharge in the second water storage chamber 16, easily cause the rainwater overflow, drain pipe jam scheduling problem, therefore, adopt the drain pipe that has the siphon action, and design benefit just has very apparent advantage and effect, reduce cost and guarantee smooth drainage.
Still include atmospheric pressure balance tube 40, the both ends of atmospheric pressure balance tube 40 communicate respectively converging pipe 3 and the upper portion region in second water storage chamber 16, guarantee that the atmospheric pressure of converging pipe 3 and second water storage chamber 16 is balanced, guarantee that drain pipe 2 drains water smoothly.
