the lower parts of the two walls 1 are respectively provided with a through hole for communicating the upstream and the downstream with the lock chamber, a gate valve 10 for controlling the opening and the closing of the gate valve is arranged in each through hole, one end of each gate valve 10, which is close to the suspension frame 4, is communicated with the annular cavity 7 through a soft water pipe 9, one end of each gate valve 10, which is far away from the water pipe 9, is communicated with the upstream and the downstream respectively, and the water in the upstream and the downstream can be communicated with the lock chamber through the gate valves 10, the water pipes 9, the annular cavity 7 and the.
The area of an opening at the lower side of an inner ring of the suspension frame 4 is smaller than the sectional area of the rubber bag 5, a plurality of process grooves which are not communicated with the annular cavity 7 are formed in the suspension frame 4, the notch of each process groove is sealed by spot welding, and the process grooves can reduce the overall mass of the suspension frame 4, so that the comprehensive density of the suspension frame 4 and the rubber bag 5 is reduced, and the working load of an external traction device is reduced; each branch pipe 8 penetrates from the side wall of the rubber bladder 5 to the inside thereof.
The inner wall of the part of the branch pipe 8, which is positioned in the rubber bag 5, is fixedly embedded with a plurality of special-shaped bulges 11, the special-shaped bulges 11 are square and hemispherical, two adjacent special-shaped bulges 11 are staggered with each other, and the maximum size of each special-shaped bulge 11 on the cross section perpendicular to the axial direction of the branch pipe 8 is less than half of the pipe diameter of the branch pipe 8, so that the rubber bag 5 is prevented from completely sealing the branch pipe 8 when being extruded by a ship; the square and hemispherical irregular protrusions 11 can make the water in the branch pipe 8 flow more disorderly, enhance the vibration generated in the branch pipe 8 and ensure that the viscosity of the non-Newtonian fluid 6 keeps a higher level.
In the invention, the river banks on two sides are provided with the traction devices for drawing the suspension frame 4 to move up and down, the traction devices can drive the suspension frame 4 to move up and down in water when working, the suspension frame 4 is made of materials with higher hardness such as stainless steel, and the like, so that the integral density of the suspension frame 4 and the rubber bag 5 is higher than that of water, namely, the suspension frame 4 is partially sunk below the water surface under the condition of no external force (the traction devices do not work).
When the ship needs to pass through the gate, firstly opening the entry gate (if the upper gate is the entry gate, otherwise, the lower gate is the entry gate), the ship completely enters the gate chamber to close the entry gate, the traction device starts to pull part of the suspension frame 4 to move upwards until the rubber bag 5 abuts against the bottom of each ship, the bottom of each ship is at least embedded into the rubber bag 5 for one meter, and after each ship is stable and does not shake or skew any more, the power of the traction device is controlled to keep the traction force of the suspension frame 4 constant, (at this time, if the traction force of the suspension frame 4 on the traction device is reduced, the traction device continues to pull the suspension frame 4 and the ship body to move upwards, otherwise, part of the suspension frame 4 moves downwards), slowly opening the gate valve 10 corresponding to the exit valve to enable water to flow (the gate valve 10 communicated with the exit valve, when the gate valve moves downwards, the gate valve 10 communicated with the downward movement is opened, otherwise, the gate valve 10 communicated with the upstream is opened when the gate valve moves upwards);

When the gate valve 10 is opened slowly, a large amount of water can circulate in the branch pipe 8, the ship can not be in a straight state in the rubber bag 5 due to the fact that the rubber bag 5 is extruded to enable the branch pipe 8, so that water in the branch pipe 8 can collide with the inner wall of the branch pipe 8 to generate vibration when flowing fast, non-Newtonian fluid 6 in the rubber bag 5 is vibrated, particularly, viscosity of the non-Newtonian fluid is obviously increased when the non-Newtonian fluid is vibrated at high frequency, solid properties are shown even, and the non-Newtonian fluid 6 in the rubber bag 5 can be kept in a shape embedded with each ship at the moment.
After the gate valve 10 is continuously opened to the maximum flow, the non-Newtonian fluid 6 in the rubber bag 5 keeps a certain degree of vibration, and the ship above the rubber bag 5 cannot generate displacement because the ship is embedded in the rubber bag 5 similar to a solid state, and cannot collide with other ships naturally.
When the ship moves upwards, water at the upstream is supplemented into the lock chamber, the water level continuously rises at the moment, the draft of each ship also synchronously rises, the buoyancy of the water to each ship is increased at the moment, namely, the tension of the suspension frame 4 part to the traction device is reduced, as mentioned above, the traction device continues to pull the suspension frame 4 part to move upwards until the tension returns to the set state, and each ship is still embedded in the rubber bag 5 during the period, namely each ship cannot deviate to generate impact.
On the contrary, when the ship descends, the water in the lock chamber flows downstream, the water level in the lock chamber continuously descends, the draft of each ship continuously descends, the buoyancy of the water to each ship is reduced, namely the tension of the suspension frame 4 to the traction device is increased, as mentioned above, the traction device is reversed to enable the suspension frame 4 to move downwards until the tension returns to the set state, and each ship is still embedded in the rubber bag 5 during the period, namely each ship cannot deviate to generate impact.
When the water levels on the two sides of the run-out valve are equal, the traction device is closed to enable the partial structure of the suspension frame 4 to sink under the action of self gravity without contacting with each ship, the run-out valve is opened, and each ship finishes the brake passing work.
Although the terms wall 1, chute 2, slide 3, suspension frame 4, rubber bladder 5, non-newtonian fluid 6, annular chamber 7, branch pipe 8, water pipe 9, gate valve 10, shaped protrusion 11, etc. are used more herein, the possibility of using other terms is not excluded.
