DETAILED DESCRIPTION

[0029] The present invention will be described in more detail below in conjunction with the schematic diagram, wherein the preferred embodiment of the present invention is shown, and it should be understood that those skilled in the art can modify the present invention described herein, and still achieve the beneficial effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation of the present invention.

[0030] like Figures 1 to 7 As shown, a hierarchical drainage ditch structure includes: an upper drainage channel 1, a lower drainage channel 2 and a drainage unit; the upper drainage channel 1 and the lower drainage channel 2 are detachably connected.

[0031] When the total amount of water is less than the set amount, the drainage unit is closed and in the interception state, and rainwater and sewage are discharged through the upper drainage channel 1; when the total amount of water is greater than the set amount, the drainage unit is closed and in the open state, connecting the upper drainage channel 1 and the lower drainage channel 2, and the water (rainwater and sewage) is discharged through the upper drainage channel 1 and the lower drainage channel 2. The specific structure of this structure is as follows:

[0032] The bottom surface of the upper drainage channel 1 is open, and a plurality of water-permeable grooves 11 are provided on the top surface to communicate with the interior of the upper drainage channel 1. An upper water diversion plate 13 is provided in the upper drainage channel 1, and two upper cross beams 12 are provided between the upper water diversion plate 13 and the two inner side walls of the upper drainage channel 1.

[0033] The lower drainage channel 2 is open to the top surface of the upper drainage channel 1 to communicate with the bottom surface of the upper drainage channel 1; a drainage unit is rotatably installed between the two inner side walls (the first inner side wall 21 and the second inner side wall 22) of the lower drainage channel 2 and the lower water diversion plate 23, and the drainage unit rotates to conduct the upper drainage channel 1 and the lower drainage channel 2. In this embodiment, a lower water diversion plate 23 is arranged in the lower drainage channel 2 along the water flow direction in the lower drainage channel, and two lower cross beams 24 are arranged between the lower water diversion plate 23 and the two inner side walls (the first inner side wall 21 and the second inner side wall 22) of the lower drainage channel; the two lower cross beams 24 are located between the adjacent first water retaining plates 32, and the drainage components 3 on both sides of each lower cross beam 24 turn in opposite directions; a pair of drainage components 3 are arranged between the two lower cross beams 24, and the pair of drainage components 3 are symmetrically arranged; the connecting shafts 31 of the pair of drainage components 3 are close to the adjacent lower cross beams 24,

[0034] The drainage unit includes two groups of drainage component 3 units which are sequentially arranged along the water flow direction in the lower drainage channel 2 and are symmetrically arranged about the lower water distribution plate 23; each group of drainage component units includes four drainage components 3 which are sequentially arranged.

[0035] Each water discharge member 3 includes a connecting shaft 31, a first water baffle plate 32 and an elastic element connected in sequence. Specifically, the connecting shaft 31 is rotatably mounted on the inner side wall of the lower water diversion plate 23, and the elastic element (spring) is welded to an inner side wall of the lower drainage channel 2; the first water baffle plate 32 is hinged to the second water baffle plate, and the area of ​​the first baffle plate is larger than the area of ​​the second water baffle plate 33. When the second water baffle plate 33 is flipped to a horizontal state, the second water baffle plate 33 and the elastic element are located on the same side of the first baffle plate; a reserved gap is formed between the second water baffle plate 33 and the second inner side wall 22, that is, at this time, the gap between the second water baffle plate 33 and the second inner side wall 22 is small. In this embodiment, the intercepting area occupied by the elastic element is small and is not considered. That is, it is considered that when the first water baffle plate 32 and the second water baffle plate 33 of the water discharge member 3 are both in a horizontal state, the water in the upper drainage channel 1 passes through the gap between the elastic element, the second water baffle plate 33 and the second inner side wall 22, and the amount of water flowing into the lower city drainage channel is negligible.

[0036] In this embodiment, the hinge structure between the first water baffle plate 32 and the second water baffle plate includes: a hinge seat, a hinge shaft and a swing bar; the hinge seat is fixed to the upper end surface of the first water baffle plate 32, the swing bar is fixed to the upper end surface of the second water baffle plate 33, the swing bar is sleeved on the hinge shaft, and the hinge shaft is rotatably installed on the hinge seat.

[0037] In this embodiment, the interception principle of the drainage unit is as follows: in the two water flow channels of the lower drainage channel 2, each water flow channel is composed of two lower cross beams 24 and four drainage components 3 in an interception state (horizontal state), which intercept the water in the upper drainage channel 1 in the water flow channel of the upper drainage channel 1.

[0038] Working principle of the hierarchical drainage ditch structure:

[0039] Step 1: Install the drainage components 3 and adjust each drainage component 3 to a horizontal state to separate the upper drainage channel 1 and the lower drainage channel 2.

[0040] Specifically, each water discharge component 3 is installed in the lower drainage channel 2 in turn, the first water baffle 32 of each water discharge component 3 is adjusted to a horizontal state, and then the second water baffle 33 of each water discharge component 3 is flipped to a horizontal state. At this time, the second water baffle 33 in each water discharge component 3 is coplanar with the corresponding first water baffle 32, and a reserved gap is formed between the second water baffle 33 of each water discharge component 3 and the corresponding second inner wall 22.

[0041] Step 2: clamp the upper drainage channel 1 on the lower drainage channel 2 so that the top surface of the lower drainage channel 2 facing the upper drainage channel 1 is connected to the bottom surface of the upper drainage channel 1. At this time, the drainage unit is in a cut-off state.

[0042] Step 3: On rainy days, when the total amount of water is less than the set amount of water, rainwater enters the upper drainage channel 1 through the permeable groove 11 and is discharged along the upper drainage channel 1, and the drainage component 3 is still in the interception state.

[0043] When the total amount of water is greater than the set amount of water, the water discharge member 3 is opened. Specifically, the first water baffle plate 32 and the second water baffle plate 33 of each water discharge member 3 are turned along the corresponding connecting shaft 31 to enter the open state, and the elastic element is twisted with the first water baffle plate 32.

[0044] After the drainage member 3 is opened, the upper drainage channel 1 is connected to the lower drainage channel 2, a part of the water in the upper drainage channel 1 enters the lower drainage channel 2 and is discharged from the lower drainage channel 2, and the other part of the water is discharged from the upper drainage channel 1.

[0045] When the total amount of water gradually decreases, the whole formed by the second water baffle plate 33 and the first water baffle plate 32 automatically rotates back to the horizontal state (intercepting state) under the action of the elastic element.

[0046] The above is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any technician in the relevant technical field, without departing from the scope of the technical solution of the present invention, makes any form of equivalent replacement or modification to the technical solution and technical content disclosed in the present invention, which does not depart from the content of the technical solution of the present invention and still falls within the protection scope of the present invention.
