Referring to fig. 1 to 3, the present invention provides an off-line rainwater storage tank, which includes a rainwater compartment 100 and a storage tank 200. The rain compartment 100 is a rain water circulation pipe. The rainwater flow pipeline specifically refers to a flow pipeline of a rainwater pipe canal, and the rainwater pipe canal is a pipeline for collecting and conveying rainwater and is used for timely removing rainwater to prevent rainstorm and water accumulation on the ground of urban residential areas and industrial enterprise areas from influencing normal life and production. Specifically, the rainwater pipe duct includes pipelines such as a street rainwater branch pipe, a factory rainwater branch pipe, a street rainwater branch pipe, and a town rainwater trunk pipe, so the rainwater compartment 100 may be a rainwater flow pipeline of the street rainwater branch pipe, the factory rainwater branch pipe, the street rainwater branch pipe, the town rainwater trunk pipe, and the like, and this application does not give an example.

The storage tank 200 is disposed along the rainwater flow pipe and is located at one side of the rainwater compartment 100 along the extending direction of the rainwater flow pipe. Referring to fig. 1, the direction indicated by the arrow in the drawing is the extending direction of the rainwater flow pipe, i.e., the extending direction of the rainwater compartment 100. The regulation pond 200 is equipped with inlet opening 210 and apopore 220 to communicate with rainwater cabin 100 through inlet opening 210 and apopore 220, be used for sharing the peak flow of rainwater runoff in rainwater cabin 100, with the reduction flood peak flow, improve regional drainage standard and flood control ability, reduce urban waterlogging. Fig. 2 shows a cross-sectional view at 1-1 in fig. 1, in which the direction directed perpendicularly to the paper plane is the direction of extension of the rainwater flow pipes, and the direction indicated by the arrow is the direction of flow of rainwater during peak flow rainwater storage. Referring to fig. 2, the water inlet 210 is located above the water outlet 220, the flap valve 110 is disposed in the rainwater cabin 100, the flap valve 110 is hinged to the inner wall of the rainwater cabin 100, the hinged position is located above the water outlet 220, and in a natural state, the flap valve 110 falls under the action of gravity and has a first state of shielding the water outlet 220; in addition, when the flap door 110 is rotated by a certain angle around the hinge position by an external force, the flap door 110 has a second state of opening the water outlet hole 220.

It should be noted that, the hinge structure of the flap door 110 and the inner wall of the rain water chamber 100 may be specifically a pin shaft connection, and the flap door 110 can rotate relative to the inner wall of the rain water chamber 100 through the pin shaft under the action of an external force, so as to change from a first state of shielding the water outlet hole 220 to a second state of opening the water outlet hole 220.

When the rain is not raining, the flow of rainwater in the rainwater circulation pipeline is less, no rainwater exists in the storage tank 200, and the flap valve 110 hinged to the inner wall of the rainwater cabin 100 naturally falls under the action of gravity and is in a first state of shielding the water outlet hole 220. When the rainfall is less in dry seasons, the flow of the rainwater collected in the rainwater circulation pipeline is small, the liquid level line in the rainwater cabin 100 is lower and does not exceed the height of the water inlet hole 210, water does not enter the storage tank 200, and the storage regulation space is not started. In this case, the flap 110 maintains the first state of shielding the outlet hole 220 under gravity or under the pressure of rainwater in the rainwater chamber 100, and rainwater flows only in the rainwater chamber 100 until it is drained.

When the rainfall is more in rainy season, the flow of the rainwater collected in the rainwater circulation pipeline is increased, and the water level in the rainwater cabin 100 is increased accordingly. After the water level line in the rain cabin 100 rises to a height higher than the water inlet 210, the rain water in the rain cabin 100 overflows into the storage tank 200 through the water inlet 210, and the storage space is started to temporarily store the flood peak rain water, so that the water level line in the storage tank 200 gradually rises. Rainwater can reduce the rainwater peak flow in the rainwater pipe canal after flowing into the regulation and storage pond 200, alleviates the drainage pressure of rainwater pipe canal to improve regional drainage standard and flood control ability, reduce the waterlogging calamity.

As the rainfall decreases, the runoff of rainwater in the rainwater canals decreases, and the water level line in the rainwater compartment 100 decreases accordingly. When the water level in the rainwater compartment 100 drops below the inlet, rainwater stops flowing into the storage tank 200, and thereafter the water level in the storage tank 200 is maintained at a fixed value. The water level line in the rainwater cabin 100 continues to slowly decrease along with the gradual emptying of rainwater, when the water level line in the rainwater cabin 100 decreases to reach a set value with the water level difference in the storage tank 200, the flap valve 110 rotates relative to the inner wall of the rainwater cabin 100 under the pressure generated by the water level difference at the two sides, the flap valve 110 is adjusted from a first state of shielding the water outlet hole 220 to a second state of opening the water outlet hole 220, and the rainwater stored in the storage tank 200 flows back into the rainwater cabin 100 again through the water outlet hole 220. After rainwater in the storage tank 200 is drained, the flap valve 110 naturally falls under the action of gravity, and the first state of blocking the water outlet hole 220 is recovered, so that the effect of regulating and storing the peak flow of rainwater is achieved again when the next rainstorm occurs.

Wherein, for making rainwater and the sedimentary silt in the rainwater in the regulation pond 200 all can the evacuation, set up apopore 220 in the bottom of regulation pond 200. In order to accelerate the emptying of rainwater in the storage tank 200, the water outlet hole 220 is designed to be a rectangular hole elongated along the extending direction of the rainwater cabin 100, and the longer the length along the extending direction of the rainwater cabin 100 is, the larger the sectional area of the water outlet hole 220 is, and the faster the outflow speed of rainwater is. Simultaneously, the increase sectional area can avoid in the rainwater miscellaneous debris to shelter from apopore 220, and furthest increases out the water width, reduces out the water dead angle, avoids the silt of bottom of the pool to pile up.

Further, set up the horizontal slope towards apopore 220 direction at the bottom of regulation pond 200, the direction slope that is close to apopore 220 descends gradually. When the flap valve 110 is in the second state of opening the apopore 220, silt has the trend of flowing to apopore 220 under the action of gravity, along with the washing away of rainwater, flows out from apopore 220 along horizontal ramp, avoids the bottom of the pool silt deposit too much to block up apopore 220 to reduce the maintenance cost of regulation pond 200.

Fig. 3 shows a cross-sectional view at 2-2 in fig. 1, where the direction indicated by the arrow is the direction of extension of the storm water flow conduit. Referring to fig. 2 and 3, the grid 211 is disposed at the inlet 210 to primarily filter rainwater flowing from the rainwater compartment 100, and when more impurities are mixed in ground rainwater collected in the rainwater conduit, the grid 211 can prevent the impurities from blocking the inlet 210 and the outlet 220, so as to avoid affecting the use of the storage tank 200. It should be noted that the size of the inlet opening 210 is determined according to the designed flow capacity of the rainwater flow pipe, and the designed flow capacity must meet the requirement of reducing the peak flow in the rainwater compartment 100.

In the whole working process of the rainwater storage tank 200, the water inlet node of the storage tank 200 is determined by the opening height of the water inlet hole 210, the water outlet node of the storage tank 200 is determined by the water level difference of the storage tank 200 and the rainwater cabin 100, manpower or electric power control is not needed in the whole process, and the full-automatic off-line rainwater storage and regulation by waterpower is realized. Simultaneously, the rainwater accessible automatic apopore 220 evacuation of opening of the rainwater accessible water conservancy of storing in the regulation pond 200 is to rainwater cabin 100, need not elevator pump, row's mud equipment and detection controlgear etc. has reduced manpower and materials's input, has reduced the operation energy consumption.
