The bottom of the door body 220 is provided with an outer chamber 2202 with variable capacity and communicated with the inner chamber 2201;
as the capacity of the inner chamber 2201 changes, the capacity of the outer chamber 2202 changes according to the following condition: the volume increment of the outer chamber 2202 is equal to the volume decrement of the inner chamber 2201, and the volume decrement of the outer chamber 2202 is equal to the volume increment of the inner chamber 2201.
The length of the outer chamber 2202 increases as the capacity of the outer chamber 2202 increases, and decreases as the capacity of the chamber decreases.
Then the effect is produced, the flow is increased due to the surge, the non-Newtonian fluid in the inner chamber 2201 flows into the outer chamber 2202, the outer chamber 2202 with the increased length extends downwards, the non-Newtonian fluid is impacted by the water flow, the viscosity of the non-Newtonian fluid is increased to form a form close to solid, the water flow is blocked, the cross section area of the opened gate is reduced through phase change, the gate flux is reduced, and the gate flux is reduced along with the change of the water flow surge.
Conversely, when the surge causes a decrease in flow, the outer chamber 2202 reduces in volume, retracts upward, increases in phase the cross-sectional area of the gate opening, increases in gate flux, and increases in gate flux with changes in water flow surge.

The surging flow increasing range movable plate 2203 overcomes the elastic force of the elastic piece to compress inwards to reduce the capacity of the inner cavity 2201, and the surging flow decreasing range elastic piece releases accumulated potential energy to push the movable plate 2203 to return to the balanced position.
The change in volume of the outer chamber 2202 is: the bottom of the door body 220 is provided with a groove, an inflated elastic bag 2204 in a cuboid shape is arranged in the groove, the inner space of the elastic bag 2204 forms an outer chamber 2202, and an opening of the elastic bag 2204 is connected with the door body 220 and is communicated with an inner chamber 2201 of the door body 220.
Initially, the elastomeric bladder 2204 has a minimum volume and is received within the recess of portal 220, and as the volume of the interior chamber 2201 changes, the non-Newtonian fluid flows into or out of the elastomeric bladder 2204, passively changing the volume of the exterior chamber 2202 of the elastomeric bladder 2204.
The elastic member can be selected from, but not limited to: a spring and an air bag.
