Referring to fig. 1, a rainwater collecting tank structure includes a rainwater collecting tank 3, wherein the rainwater collecting tank 3 is communicated with a main drainage channel 1 through a water inlet channel 2 so as to introduce fluid in the main drainage channel 1 through the water inlet channel 2; the design elevation of the bottom of the water inlet flow channel 2 is higher than the design elevation of the bottom of the main drainage flow channel 1 and the bottom of the rainwater collecting pool 3. And a grid 21 is arranged on the water inlet flow channel 2 and is used for blocking sundries and silt. The mesh 21 is preferably provided at the inlet end of the inlet channel 2.

The rainwater collecting pool structure of embodiment, the bottom that makes intake runner 2 is higher than main drainage runner 1, debris, silt etc. precipitate in main drainage runner 1's bottom, and the rainwater of collecting the recovery through intake runner 2 is the clear rainwater in upper strata, and the rainwater suspended solid of guaranteeing to collect is few, the turbidity is lower, makes intake runner 2's bottom be higher than rainwater collecting pool 3's bottom, can guarantee that there is certain safe depth of water in the rainwater collecting pool 3. In practice, the main drainage channel 1 is usually a drainage channel (main channel) in a municipal or factory, and the water inlet channel 2 is a water inlet channel (branch channel) of the rainwater collection tank 3, which may be in the form of a pipeline, and is not particularly limited. During implementation, it is optional the bottom of intake runner 2 is higher than 1 bottom of main exhaust runner a meter, the bottom of intake runner 2 is higher than 3 bottoms of rainwater collecting pool a meter, when guaranteeing into water quality, guarantees that there is the safe depth of water of a meter in the rainwater collecting pool 3.

Wherein, the water inlet channel 2 and the main drainage channel 1 are respectively provided with a gate 4 so as to realize collection or drainage through the opening and closing correspondence of different gates 4. And a first liquid level meter is arranged in the rainwater collecting tank 3 and is in signal connection with control mechanisms of the two gates 4.

Therefore, the device is convenient to control and use and improves the collection efficiency. During the implementation, under the general condition (collect the retaining state), liquid level in first level gauge detection rainwater collecting tank 3 does not reach design retaining liquid level, and transmission signal control closes gate 4 on main drainage runner 1, opens gate 4 on the runner of intaking 2, all collects rainwater collecting tank 3 with the clearer rainwater in upper strata. Because the bottom of the water inlet flow channel 2 is higher than the bottom of the main drainage flow channel 1 and the inlet is provided with the grid 21, sundries and silt are deposited and blocked outside the grid 21 and at the bottom of the main drainage flow channel 1. The first liquid level meter detects that the liquid level in the rainwater collecting pool 3 reaches the designed water storage liquid level, the gate 4 on the water inlet flow channel 2 is closed under the control of a transmission signal, the gate 4 on the main drainage flow channel 1 is opened, rainwater in the main drainage flow channel 1 is drained, and sediments such as sundries, silt and the like are flushed away to carry out self-cleaning. Through this kind of mode, most silt can't get into rainwater collecting tank 3, can guarantee that the rainwater suspended solid and the turbidity of collecting are lower.

And a second liquid level meter is arranged in the main drainage flow channel 1 and is in signal connection with control mechanisms of the two gates 4.

Thus, when necessary, the gate 4 on the water inlet runner 2 can be controlled to be closed and the gate 4 on the main drainage runner 1 can be opened by priority transmission signals, so that the function of ensuring safe drainage is achieved. In practice, the second liquid level meter is selected to be arranged in a flow passage in front of the gate 4 of the main drainage flow passage 1 so as to be correspondingly detected.

Wherein, one side of the runner section that is equipped with gate 4 on main drainage runner 1 is widened and is equipped with or both sides all widen and are equipped with overflow runner 11, overflow runner 11 is with the runner intercommunication around gate 4 on the main drainage runner 1, overflow runner 11's bottom design elevation is higher than intake runner 2's bottom design elevation.

Therefore, the functional design is further improved, the main drainage runner 1 is locally widened, the sufficient overflow capacity is ensured, and the safe implementation of the engineering can be ensured under the extreme condition. Under special conditions, when the rainfall is particularly high, the front liquid level of the gate 4 on the main drainage runner 1 rapidly rises to exceed the warning liquid level, and flood drainage is needed, and at this time, the gate 4 on the main drainage runner 1 cannot be opened due to the circumstances, so the overflow runner 11 on the side of the gate 4 on the main drainage runner 1 can also ensure the flood drainage, and therefore, the overflow runner 11 should be widened to the width enough to ensure the overflow capacity, and the design of widening two sides is adopted in the embodiment; in addition, the liquid level of elevating setting in main exhaust runner 1 of inhalant canal 2 can inevitably cause the influence of choking, so, the bottom design elevation of overflow runner 11 should be higher than inhalant canal 2's bottom design elevation, still be higher than the liquid level height of choking of inhalant canal 2 position department better, or according to the effect when this design of choking liquid level height of punishment is in order to ensure normally to collect the rainwater.

Among them, it is preferable that the water inlet flow passage 2 is horizontally and vertically disposed to the main water discharge flow passage 1.

Therefore, the collecting flow speed can be effectively controlled, and the realization of the effect is further ensured.

Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the scope of the claims of the present invention.
