Detailed Description
The technical solution of the present invention is further described in detail with reference to the accompanying drawings, but the scope of protection is not limited thereto.
Referring to fig. 1, one embodiment of the present invention provides an arc door capable of automatically controlling an upstream water level by using buoyancy, which includes a gate wall 1, a water inlet pipe 3 disposed on the gate wall 1, a water outlet pipe 2 disposed on a side of the gate wall 1, a water outlet pipe 9, an arc door 4 disposed on an outer end of the gate wall 1, and a hinged floating mechanism connected to the arc door 4, wherein the hinged floating mechanism includes an arc door buoyancy tank 5, an arc door support arm 7 connected to the arc door buoyancy tank 5, and an arc door support hinge 6 hinged to one end of the arc door support arm 7, the arc door buoyancy tank 5 is connected to an upper portion 41 of the arc door 4 to form a fan-shaped structure, a lower portion 42 of the arc door 4 extends downward from the upper portion 41 of the arc door 4, and when the bottom surface of the fan-shaped structure is connected to the bottom surface of theWhen touching, the lower part 42 of the arc door 4 is connected with the lower part of the bottom surface of the gate wall 1OrificeAnd (6) turning off.
The buoyancy tank 5 is in a completely sealed state, a cavity 8 is formed by enclosing between the arc door 4 and the gate wall 1, the arc door support hinge 6, the arc door support arm 7 and the arc door buoyancy tank 5 are positioned in the cavity 8, one end of the water inlet pipe 3 is positioned on the upper portion of the gate wall 1, and the other end of the water inlet pipe is positioned on the lower portion of the gate wall 1 and is communicated with the cavity 8. The water outlet pipe 9 is positioned at the upper part of the water outlet pipe 2, the position of the water outlet pipe 9 is higher than the outlet of the water inlet pipe 3, the section of the water outlet pipe 9 is larger than that of the outlet of the water inlet pipe 3, and the section of the water outlet pipe 2 is far smaller than that of the water inlet pipe 3. The inlet of the water inlet pipe 3 is higher than the normal water storage level of the upstream, can be set to the maximum flood level of the upstream, and the water outlet pipe 9 is positioned in the cavity 8 and can be set to the maximum water level of the downstream.
The utility model discloses the theory of operation does: when the upstream water level is lower than the normal water storage level, no water exists in the cavity 8, and the arc door 4 closes to block water under the action of self weight.
When the upstream water level rises and reaches the maximum flood level, the upstream water enters the cavity 8 through the water inlet pipe 3, meanwhile, the water outlet pipe 2 on the side surface of the gate wall 1 begins to drain water to the downstream, the cross section of the water outlet pipe 2 is far smaller than that of the water inlet pipe 3, therefore, the water level in the cavity 8 rises continuously, the floating box 5 floats upwards slowly along with the rise of the water level to drive the arc door support arm 7 to rotate around the arc door support hinge 6, the arc door 4 is opened (as shown in fig. 2), when the water level in the cavity 8 rises to a certain elevation, the opening degree of the arc door 4 reaches a designed value, at the moment, the water outlet pipe 9 arranged on the side surface of the gate wall 1 begins to discharge water, the cross section of the water outlet pipe 9 is larger than that of the water inlet pipe 3, the water level in the cavity 8 is kept unchanged, the.
When the upstream water level is discharged below the maximum flood level, the water cannot enter the water inlet pipe 3, the water in the cavity 8 cannot be supplemented, the water discharge pipe 2 on the side surface of the gate wall 1 continues to discharge water, the water level in the cavity 8 continuously descends, the floating box 5 begins to sink until the water in the cavity 8 is completely emptied, and the arc door 4 is completely closed under the action of self weight.
In the arc door opening and closing process, the cavity 8 is always disconnected with the downstream water body, the downstream water body cannot be poured into the cavity 8, and the downstream highest water level line cannot exceed the highest water blocking line of the arc door 4.
