Detailed Description
The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, which are not intended to limit the present invention, but are given by way of example only.
The air bag type automatic water retaining sill shown in fig. 1 and 2 comprises a water retaining cover plate 1, a steel plate 2, an air bag 5, a support 6 and an air storage bottle 8, wherein a buoyancy valve 9 is mounted on the air storage bottle 8, and the opening and closing of the buoyancy valve 9 are controlled by a buoyancy rod 10 extending outwards. A groove 4 and a working well 7 are reserved on the entrance and exit bottom plate F, and a blocking ridge 13 for preventing the water-retaining cover plate 1 from being overturned excessively is pre-buried in the entrance and exit side wall B.
The width of the groove 4 is matched with the width of the water retaining cover plate 1, and the depth is the sum of the thicknesses of the water retaining cover plate 1 and the support 6. The steel members of the support 6 are pre-buried in the side walls of the groove 4 during construction. The water retaining cover plate 1 is made of light metal and is convenient to open and close, and a buffer rubber strip which is in contact with the water retaining cover plate 1 can be arranged in the groove 4 for reducing metal impact noise when pedestrians walk.
The pre-buried steel sheet 2 of the lee side of recess 4, manger plate apron 1 is connected with steel sheet 2 through pre-buried hinge 3 on access & exit bottom plate F, can realize through this hinge 3 that the dry season hides manger plate apron 1 in access & exit bottom plate F, becomes access & exit bottom plate F's component part, does not influence personnel's traffic and access & exit pleasing to the eye.
The gasbag 5 passes through support 6 to be installed in recess 4, gasbag 5 can bear 1.5 ~ 2 atmospheric pressure, forms the post with the side wall under the inflation state, prevents flood side direction seepage, and gasbag 5 bears the horizontal pressure of flood under the supporting role of manger plate apron 1 class simultaneously.
The gas bomb 8, the buoyancy valve 9 and the buoyancy rod 10 are all located in the working well 7. The working wells 7 are positioned below the grooves 4, and the number of the working wells can be one or two, so that the opening guarantee degree of the air bags 5 is improved. The number of the gas cylinder 8 may be one or more to satisfy the atmospheric pressure amount of the airbag 5.
Still pre-buried inlet tube 11 and outlet pipe 12 in the access & exit bottom plate F around the working well 7, can realize coming temporarily at the flood, fill working well 7 with water rapidly through inlet tube 11, buoyancy pole 10 upwards opens certain angle under the buoyancy of water, opens buoyancy valve 9, then opens gas holder 7, inflates to gasbag 5, along with gasbag 5 ground inflation manger plate apron 1 upwards turns over gradually, until keeping off bank 13 and counterbalance, the angle of opening of manger plate apron 1 can be controlled to fender bank 13 pre-buried on left and right access & exit side wall B, contained angle alpha with steel sheet 2 when manger plate apron 1 opens is not less than 90. When the flood is removed and the flood in the working well 7 is drained through the water outlet pipe 12, the buoyancy rod 10 is reset, the buoyancy valve 9 is closed, the air vent on the air bag 5 is opened, and the air bag is placed in the groove 4 and covered with the water retaining cover plate 1 after the air is drained.
Firstly, a groove 4 needs to be reserved on an entrance and exit bottom plate F, and the opening size of the groove 4 is matched with the plane size of the water retaining cover plate 1; the width is generally 400mm to 500mm, and the thickness is generally 200mm to 300 mm.
And secondly, embedding a steel plate 2 on the backwater side of the groove 4, and embedding a support 6 in the groove 4.
Thirdly, reserving one or two working wells 7 below the groove 4, wherein the size of each working well 7 is generally 800mm x 800mm x 500mm so as to meet the requirements of article placement and personnel maintenance; the inlet pipe 11 and the outlet pipe 12 are embedded in the inlet and outlet bottom plate F around the working well 7.
And fourthly, installing the air bag 5 in the groove 4, placing the air storage bottles 8 in the working well 7, wherein the quantity of the air storage bottles 8 is matched with the air quantity of the air bag 5.
And fifthly, embedding a blocking ridge 13 in the side wall B of the entrance/exit.
And sixthly, connecting the steel plate 2 with the water retaining cover plate 1 through a hinge 3.
The application of automatic manger plate threshold of gasbag formula in preventing that flood flows backward specifically is: flood enters the working well 7 from the water inlet pipe 11, the buoyancy rod 10 moves upwards under the action of buoyancy of the water to open the buoyancy valve 9, the gas storage cylinder 8 starts to inflate the gas bag 5, the water retaining cover plate 1 gradually turns upwards along with the expansion of the gas bag 5 until abutting against the retaining ridge 13, the gas bag 5 becomes a water retaining sill for blocking the backward flow of the flood together with the water retaining cover plate 1 after being full of, and the gas bag 5 is tightly attached to the side wall F of the inlet and the outlet. After the water is drained, the water in the working well 7 is discharged from the water outlet pipe 12, the buoyancy rod 10 is reset, the buoyancy valve 9 is closed, the air vent on the air bag 5 is opened until the air is completely discharged, the air bag 5 is put into the groove, and the water retaining cover plate 1 is closed.
