The plan views shown in fig. 5 and 6 illustrate the sealing principle, and in order to clearly show the boundaries of the structures, partial separation treatment is performed, and the sealing matching relationship is not affected.

When the water level intercepting device is used, the gate door body 10 is in sealing fit with the bottom and two sides of the gate frame assembly in a sealed water storage state, so that water level interception is realized; when the gate door body 10 is opened to need and is let off water, driving motor 16 rotates, through drive gear 18 and the transmission of follow-up gear 17, drives the gate door body 10 level and rotates, and in the recess 3 interval, the gate door body 10 keeps encapsulated situation between all the time and the stand 28, and the bottom keeps sealed simultaneously, and usable this interval carries out sealed regulation, if sealed problem appears because of the cooperation, can rotate the regulation, staggers and reveal the position to keep sealed effect. When the gate body 10 rotates through the groove 3, a water discharge channel is formed. When the gate door is closed, the driving motor 16 rotates reversely to drive the gate door 10 to reset, and if the installation matching is strong, the gate door 10 can also rotate continuously along the circumference to open and close.

The sealing of the bottom is realized by the sealing contact and matching of the jacked elastic membrane 9 part and the bottom end of the gate door body 10, and the jacking plate 7 jacks up the elastic membrane 9 part right above the jacking plate, so that the elastic membrane 9 is partially lifted and is sealed by extrusion contact with the gate door body 10. When the gate door body 10 rotates, under the effect of magnetic attraction, the rotation is followed to jacking board 7, make the 9 parts of elastic membrane that correspond gradually by jack-up and gate door body 10 sealing contact, when the partly of elastic membrane 9 is driven and is lifted, the grit of its top can take the advantage of the situation and drop to low department, at continuous rotation in-process, form the promotion effect to the grit, discharge the grit, then reduce the elastic membrane 9 of the contact of the gate door body 10 and go up remaining grit, reduce the destruction to sealing. The elastic membrane 9 terminal surface of jacking part contacts with the gate door body 10 all the time, can avoid the subsequent entering of grit to pile up, and simultaneously under the state of opening the gate door body 10, the lifting part direction is the same with the rivers direction, can not hinder the rivers of bottommost and flow.

The width of the jacking plate 7 is smaller than that of the gate door body 10, and the length of the jacking plate 7 is not smaller than that of the gate door body 10.

The tap ball 21 may perform a tap or stroke-like action. The elastic membrane 9 is enabled to form a protrusion by the jacking plate 7, meanwhile, two sides of the lifting end face are in a downhill state, when the jacking plate 7 rotates horizontally, the protrusion portion of the elastic membrane 9 changes along with the elastic membrane, but the elastic membrane 9 does not translate completely and synchronously, the jacking plate 7 can move firstly, the horizontal space between the downhill portion of the elastic membrane 9 and the jacking plate 7 can be compressed, namely, the spring 20 can be compressed, the elastic membrane 9 and the knocking ball 21 are subjected to friction force and blocking force, when the spring 20 has large accumulated potential, the elastic membrane is larger than the friction force and the shape blocking force, the knocking ball 21 can be pushed out, the downhill portion of the elastic membrane 9 forms scratching and pushing or similar knocking actions, and accordingly, gravel above the elastic membrane can slide smoothly.

The water pump 25 is used for humidifying the sealing parts 12, the elastic membrane 9 and the like, the water seepage holes 26 are distributed above the sealing parts 12 on two sides, and the water seepage holes 26 are formed in the front side and the rear side of the gate door body 10, so that water can cover the front side and the rear side and finally flows onto the elastic membrane 9. If a plurality of the water gate opening and closing devices are arranged side by side for use, only one water pipe can be used for supplying water.

The drive motor 16 is a power take-off unit that may be fitted with a brake unit to achieve more stable positioning, a conventional prior art means in the field.
