In the figure: the device comprises an outer shell 1, an inner sleeve 2, a closure cover plate 3, an inner cover plate 4, an initial rainwater closure pipe 5, a rainwater discharge pipe 6, a vertical U-shaped pipe 7, a connecting rod 8 and a gate 9.
Detailed Description
The following describes embodiments of the present invention with reference to the accompanying drawings.
Example 1:
referring to fig. 1-6, the environment-friendly rainwater grate for intercepting and shunting initial rainwater comprises an outer shell 1, an inner sleeve 2 is installed inside the outer shell 1 in a hanging mode through an elastic connecting piece, an intercepting cover plate 3 used for intercepting the initial rainwater is arranged between the outer shell 1 and the inner sleeve 2, an inner cover plate 4 is arranged in the center of the top of the inner sleeve 2, a rainwater discharge pipe 6 is arranged at the bottom of the outer shell 1, and the bottom of the outer shell 1 is communicated with an initial rainwater intercepting pipe 5. Can carry out the reposition of redundant personnel that dams to initial stage rainwater, finally arrange to sewage treatment plant through sewage conduit and handle.
Furthermore, the elastic connecting piece adopts an elastic rope or a spring and utilizes the self gravity to adjust and control.
Preferably, the initial elastic force of the elastic string or the spring is greater than the gravity of the inner sleeve 2, and the elastic force is less than the total weight of the inner sleeve and the water after the inner sleeve 2 is filled with the water, so that the inner sleeve can automatically fall. Thereby driving the connecting rod 8 and controlling the gate 9 to close.
Furthermore, the closure cover plate 3 is provided with uniformly distributed through holes. Can be used for assembling the rainwater through the through-hole, the through-hole area can be adjusted according to catchment area size moreover.
Further, a vertical U-shaped pipe 7 for realizing siphon is arranged on the rainwater discharge pipe 6. Can realize the automatic of rainwater through the siphon principle through setting up vertical U type pipe 7 and discharge to guarantee that the initial stage rainwater can not discharge municipal rainwater pipeline.
Further, a gate 9 is arranged on the initial rainwater intercepting pipe 5, and the gate 9 is connected with the inner sleeve 2 through a connecting rod 8. The gate can be conveniently controlled by the connecting rod 8.
Further, a trap is mounted on the initial rainwater intercepting pipe 5. The odor is blocked by the trap.
Further, the initial rainwater intercepting pipe 5 is connected with a municipal sewage pipeline, and the rainwater discharge pipe 6 is connected with the municipal sewage pipeline. By the connection mode, the initial rainwater can be conveniently intercepted and collected, and the initial rainwater can be prevented from being discharged into a municipal rainwater pipeline; can discharge middle and later stage rainwater to guarantee that middle and later stage rainwater can not discharge into municipal sewage pipeline.
The utility model discloses a working process and principle:
in the early stage of rainfall, the initial rainwater is gradually gathered near the rainwater grate and firstly enters the space between the inner sleeve 2 and the outer shell 1 of the rainwater grate through the closure cover plate 3;
step two, discharging initial rainwater to a municipal sewage pipeline through an initial rainwater intercepting pipe 5 after the initial rainwater enters the rainwater grate;
step three, with the continuous rainfall, the rainwater flow is larger and larger, and the rainwater enters the rainwater grate inner sleeve 2 after passing through the closure cover plate 3; the rainwater in the inner rainwater grate sleeve 2 falls to the bottom of the rainwater grate shell under the influence of self gravity as the rainwater is more and more, and the initial rainwater intercepting pipe gate 9 is controlled to be closed through the connecting rod 9; at the moment, the closure cover plate 3 and the inner cover plate 4 of the rainwater grate are filled with water, and the water level in the rainwater grate is higher and higher;
step four, when the water level is higher than the top of the vertical U-shaped pipe 7, rainwater begins to be discharged to form inverted siphon, rainwater in the rainwater grate shell 1 is completely discharged, the rainwater grate inner sleeve 2 is still full of water, and the pipe gate 9 of the initial rainwater interception 5 is still closed; with the continuous rainfall, the water level continues to rise, and the process is repeated; the inner rainwater grate sleeve 2 can be used for ensuring that the initial rainwater is only cut off and shunted once in a long-time rainfall and the rainfall period is intermittent, so that the initial rainwater which is rained again after the rainwater stops in the same rainfall period can not be cut off again;
and step five, after the rainfall period is finished, the rainwater in the inner sleeve 2 of the rainwater grate is removed or naturally evaporated during manual inspection, the inner sleeve 2 is enabled to reset under the action of the elastic connecting piece, and the gate 9 is opened so as to facilitate the rainwater interception in the initial period next time.
