Detailed description of the invention
The present invention as shown in Figure 1-2, including being articulated with the gate 1 of bottom surface, river course, is located at described gate bottom the air bag 3 driving described gate to make rotary movement, is provided with upright abutment wall 2 in gate two sides, is provided with side-sealing device 4 between described gate and described abutment wall.Described air bag 3 is placed in the side of described gate 1, and is connected with air pump one.Along with air pump one carries out inflation/deflation operation, air bag 3 drives gate to lift, and reaches to block the purpose of water.
It is provided with side-sealing device 4 between described gate 1 and abutment wall 2.Due to machining accuracy reason, gap will necessarily be formed between gate 1 and abutment wall 2, affect the sealing effectiveness on gas shield dam, so needing to be provided with sealing device 4 between gate 1 and abutment wall 2, the sealing effectiveness on strengthening gas shield dam so that it is can normally work.
Gate 1 is articulated with on bottom surface, river course, can rotate with articulated mounting for axle under the driving of air bag 3, reaches to block the purpose of water, and along with the angle rotated is different, it is possible to intercept the water level of differing heights.
It is provided with leakproof adhesive tape between described gate 1 and bottom surface, river course.Prevent gate 1 from leaking with the junction of bottom surface, river course, affect sealing effectiveness.
Embodiment one
As Figure 4-Figure 6, side-sealing device 4 is the pressure bladder A being located at described gate side.Pressure bladder A is fixed on described gate by bolt and pressing plate, the pressure bladder A inflation being located on gate needing dash when, and pressure bladder A is formed with abutment wall and seals.
In order to strengthen sealing effectiveness, at least one protruding A, protruding A and described abutment wall formed by integrally casting can be provided with on described abutment wall, it is ensured that the intensity of protruding A.The width of the described projection width less than described pressure bladder A.The end face of described pressure bladder A is provided with and described protruding adaptive groove A.Described protruding A passes through a center of circle, is arranged radially.Between abutment wall and gate, form linear sealing, strengthen sealing effectiveness.
When needing Rotary grate, first by pressure bladder A exit, then by air bag fill (putting) pneumatic work, drive gate rotates, friction will not be formed with abutment wall when rotating, can be inflated to pressure bladder A by air pump two when turning to specify position, be formed with gate and seal.Avoid caulking gum in prior art long-term and abutment wall friction reality damaged, poorly sealed, the defect that service life is short.
Embodiment two
As Figure 7-8, described side-sealing device 4 is the pressure bladder B being located on described abutment wall；The side that described gate contacts with pressure bladder B is provided with protruding B, the width of the described protruding B width less than described pressure bladder B.Between abutment wall and gate, form linear sealing, strengthen sealing effectiveness.
In order to further enhance sealing effectiveness, described pressure bladder B can be provided with at least one and pass through a center of circle with described protruding suitable for B groove B, described groove B, be arranged radially.By groove B and coordinating of protruding B strengthening sealing effectiveness.
When needing Rotary grate, first by pressure bladder B exit, then by air bag fill (putting) pneumatic work, drive gate rotates, friction will not be formed with abutment wall when rotating, can be inflated to pressure bladder B by air pump two when turning to specify position, be formed with gate and seal.Avoid caulking gum in prior art long-term and abutment wall friction reality damaged, poorly sealed, the defect that service life is short.Described protruding B is welded to connect with described gate, and the anti-pressure ability that is connected firmly is strong.
Embodiment three
As shown in figs. 9-10, described sealing device includes that the sealing baffle A being located on described gate and the sealing baffle B being located on described abutment wall, described sealing baffle A are provided with sealing joint strip A, described sealing baffle B and are provided with sealing joint strip B.Described sealing baffle A is flange, and described sealing baffle B is notch board, and described sealing baffle A and sealing baffle B cooperates.The sealing baffle B utilizing the sufficient intensity with abutment wall formed by integrally casting cooperates with the sealing baffle A being located in door body and utilizes the pressure effect of air bag, good sealing effect；Being located on concrete sidewall owing to sealing baffle B is prominent, in gate rotation process, sealing baffle A does not directly contact with concrete sidewall, it is to avoid in prior art, caulking gum and abutment wall rub reality damaged, poorly sealed, the defect that service life is short.
Embodiment four
As illustrated in figs. 11-14, in embodiment three, sealing baffle B is fixed on abutment wall so technical scheme in embodiment three exists gate and can only fix aperture and can not realize the defect of any opening degree.Embodiment four improves based on embodiment three.
As shown in figure 11, the lower end of sealing baffle B is hinged on the side of abutment wall, can rotate along abutment wall, on abutment wall, riveting is fixed with dash cloth, and one end of dash cloth seals and is fixed on abutment wall, and the other end is tightly connected with sealing baffle B, realize sealing between sealing baffle B at abutment wall, prevent from leaking.
As a example by gate maximum opening (peak level can be intercepted), when gas shield dam works, airbag aeration, gate rotates, rises, the dual-side of gate drives sealing baffle B to rotate, when gate reach maximum opening stop operating time, sealing baffle B is close to gate because of gravity and hydraulic pressure comprehensive function, and water can give mono-pressure of sealing baffle B during blocking water, sealing baffle B and gate is made to realize sealing.Owing to being provided with dash cloth between sealing baffle B and abutment wall, and dash cloth and sealing baffle B, good seal between dash cloth and abutment wall.Dash cloth material is softer, moves along with the motion of gate, so will not rub between dash cloth and abutment wall, does not deposit the real defect damaged, poorly sealed that rubs in the prior art.Gatage is unrestricted simultaneously, can intercept different water level, and range is wide, simple in construction, good sealing effect.
