The following describes a dam piping emergency treatment device in detail with reference to fig. 1.
Example 1
The invention relates to a dam piping emergency treatment device which comprises a moving mechanism 3 for driving a plugging box 1 to move on a dam surface 2, wherein an opening 4 is arranged on one side, close to the dam surface 2, of the plugging box 1 in a penetrating way, a film 6 is arranged in the opening 4 through a damping structure 5, and the plugging box 1 is completely placed in water of the dam body. When the pressure of the opening 4 inside the occlusion tank 1 is high, the membrane 6 will deform outwards under the effect of the pressure and disengage from the damping structure 5. The side of shutoff case 1 runs through and is equipped with pressure release mouth 7, be equipped with the automatic closing mechanism 8 that is used for sealing pressure release mouth 7 in the pressure release mouth 7. When the pressure relief opening 7 is opened, the internal of the plugging box 1 is equal to the water pressure in the dam. The membrane 6 is also at a distance H from the mouth of the opening 4, which distance H is such that the membrane 6 will not be rubbed when moving along the dam surface, and water is also present in this distance H, so that the water pressure on both sides of the membrane 6 is equal.
The one end that shutoff case 1 kept away from opening 4 runs through and is equipped with first water inlet 9, the outside activity of first water inlet 9 is provided with first water inlet baffle 10, and first water inlet 9 is opened when the beginning, and moving mechanism 3 drives shutoff case 1 and moves on dam facing 2, and shutoff case 1 is inside to be full of water through first water inlet 9 and pressure release mouth 7.
When dam face 2 does not take place the piping, pressure release mouth 7 is opened, the shutoff case 1 is slided and is equipped with and pushes away flitch 11, and the left and right sides that pushes away flitch 11 will shutoff case 1 is cut apart into I cavity and II cavity, and outside water can get into II cavity through pressure release mouth 7, and shutoff case 1 is located between flitch 11 and film 6, II cavity intussuseption is filled with rubber blanking ball 12, pushing away flitch 11 runs through and is equipped with second water inlet 13, and outside water can get into I cavity through first water inlet 9, because water is full of in shutoff case 1 for the pressure of pushing away flitch 11 both sides equals, so can not take place to remove in shutoff case 1.
When piping occurs to the dam face 2, when the blocking box 1 moves to the piping position, the pressure in the piping channel can be obviously smaller than the pressure in the cavity II on the right side of the blocking box 1, so that water in the blocking box 1 quickly flows into the piping channel, pressure difference on two sides pushes the film 6 to deform and separate from the damping structure 5, the film enters the piping channel under the action of the impulsive force of the water, the automatic closing mechanism 8 closes the pressure relief opening 7, and therefore, after the piping channel flows into the cavity II of the blocking box 1, the water pressure in the cavity II of the blocking box 1 is smaller than the water pressure of the cavity I outside, so that the external water pressure pushes the pushing plate 11 to move rightwards, the rubber blocking ball 12 is pushed into the piping channel, and when the opening of the piping channel is large enough, the film 6 can even completely enter the piping channel to be clamped at a certain position of the piping channel, and the rubber blocking ball 12 can be clamped in the piping channel well.
