On part of construction sites, the foundation pit precipitation is often discharged into municipal sewage pipelines as waste water, so that waste is caused.
However, the water recovered at the construction site is not effective as a treatment means, and thus has not been carried out.

In this embodiment, the first cylindrical cam, the second cylindrical cam and the third cylindrical cam are all fixedly mounted on the transmission shaft of the valve core, so that the first cylindrical cam, the second cylindrical cam and the third cylindrical cam rotate synchronously with the valve core. As shown in fig. 7, the first cylindrical cam, the second cylindrical cam and the third cylindrical cam are sequentially distributed from bottom to top, and the diameter of the first cylindrical cam, the diameter of the second cylindrical cam and the diameter of the third cylindrical cam are sequentially increased.
The working principle of the linkage type time delay driving mechanism of the embodiment is as follows:
as shown in fig. 12, the upper end of the push rod contacts with the convex part of the cam profile of the cylindrical cam, the mechanical valve is in a closed state, the first compression spring is compressed between the frame and the push rod, and the elastic air bag is pressed by the pressing part of the first connecting rod to be in a contracted state;
as shown in fig. 13, the cylindrical cam is driven to rotate (which may be achieved by driving the valve core to rotate) so that the upper end of the push rod is switched to contact with the concave portion of the cam profile of the cylindrical cam, the push rod moves upward to drive the first link to swing in the clockwise direction, and the pressing portion of the first link is separated from the bottom of the elastic air bag;
as shown in fig. 14, after the pressing portion of the first connecting rod is separated from the bottom of the elastic airbag, the elastic airbag will gradually expand under its own restoring force, the expanding speed is related to the aperture of the vent hole on the cover plate, and the aperture of the vent hole is proportional to the expanding speed of the elastic airbag, so that the expanding speed of the elastic airbag can be controlled by changing the aperture of the vent hole; in the expansion process of the elastic air bag, the second pin shaft moves downwards to drive the second connecting rod to rotate along the anticlockwise direction, and the sliding rod can be driven to slide upwards in the rotation process of the second connecting rod along the anticlockwise direction;
as shown in fig. 15, the expansion of the elastic balloon is completed, the sliding rod moves up to a predetermined position, and the mechanical valve is switched from the closed state to the open state.
Therefore, the push rod and the sliding rod move asynchronously, so that the function of opening the mechanical valve in a delayed mode is achieved.
In the process of switching the rotary valve core (namely, the rotary cylinder) from a gear three to a gear eight, for example, when the water outlets are passed through four, five and seven regions, four through holes in the regions, five through holes in the regions and seven through holes in the regions are respectively and temporarily communicated with the first water outlet, and because the first cylindrical cam is respectively provided with a concave part of the first cylindrical cam at the corresponding positions of the four, five and seven regions, namely when the water outlets are passed through the four, five and seven regions, the upper end of the push rod can be contacted with the concave part of the first cylindrical cam, and if the first mechanical valve is in an open state at the moment, the first water outlet inevitably has a water leakage phenomenon.
In the embodiment, the linkage type delay driving mechanism is arranged to realize the delayed opening of the mechanical valve so as to compensate the time that the water outlet I is temporarily communicated with the through hole in some areas in the process of crossing the gear switching, and the mechanical valve is not opened in the short communication time, so that the water leakage phenomenon is avoided.
The rack 912 is provided with a tooth-lacking part 923 and a toothed part 924 for meshing with the gear;
when the tooth-lacking portion 923 of the rack 912 is opposite to the gear, the rack is disengaged from the gear, so that the knob is stopped;
the rack 912 remains engaged with the gear when the toothed portion 924 of the rack is positioned opposite the gear to allow the knob to rotate;
the rack 912 slides upward on the sliding rod 910 to move from a position where the tooth lacking portion 923 faces the gear to a position where the tooth having portion 924 faces the gear when the mechanical valve is switched from the closed state to the open state.
