Principle of operation
When the municipal subway entrance retaining dam is started from a static state, the device is placed at the position, equidistant from wall surfaces on two sides, of the subway entrance, the sucking discs 104 are sucked to the ground to play a positioning role, the device is prevented from being displaced due to buoyancy of water when the groove-shaped air bags 101 are unfolded, and the pump boxes 103 on two sides are respectively unfolded towards two sides and placed on the ground.
At this time, a wrench is used for rotating the wrench groove 215, the fourth bevel gear 201 is driven to rotate through gear set transmission, the screw 203 is driven to rotate, the screw 203 and the nut 204 are in threaded transmission, so that the two parts of the middle box 105 move towards the wall surfaces on the two sides of the subway entrance, the baffle plates 102 on the two sides are respectively extruded and fixed with the wall surfaces on the two sides of the subway entrance, and the groove-shaped air bag 101 is formed through inflation.
When the water flow comes, the water flow enters the pump box 103 and flows through the blades 307, the blades 307 have a certain inclination angle with the water flow direction, and the blades 307 on both sides of the water feeding cylinder 301 have an inclination angle opposite to the water flow direction and opposite to the direction of the force generated by the water flow, so that the eccentric wheel 304 rotates. When the blade 307 rotates to the turning shifting block 309, the turning shifting block 309 shifts the turning piece 308 to rotate for a certain angle, so that the inclination angles of the blade 307 on the two sides of the water supply cylinder 301 and the water flow direction are always kept opposite.
At the moment, the eccentric shaft 306 pushes the piston 302 to reciprocate along the direction of the water supply cylinder 301, when negative pressure exists in the water supply cylinder 301, the water inlet ball 316 is separated from the water inlet valve body 315, water flows into the water supply cylinder 301, when high pressure exists in the water supply cylinder, the water inlet ball 316 is contacted with the water inlet valve body 315, the water outlet ball 314 is separated from the water outlet valve body 312, the water flows into the bottom of the groove-shaped air bag 101 through the water outlet pipe 311, as the water flow at the bottom of the groove-shaped air bag 101 increases, the groove-shaped air bag 101 is pressed to the ground by the water pressure in the groove, as long as the water flows into the pump box 103, the groove-shaped air bag 101 is pressed more tightly until the water flow is cut off, and therefore the water flow is prevented from entering the subway station.
The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention, and all equivalent structures or equivalent processes performed by the present invention or directly or indirectly applied to other related technical fields are also included in the scope of the present invention.
