Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings:
As it is shown in figure 1, a kind of portable underground hydrant include upper and lower closed at both ends vertically fixing pipe 13, can along the first piston 4 that the most fixing pipe slides, be arranged on the most fixing pipe in and the vertical lifting pipe 1, the self adaptation mechanism for opening/closing being arranged in the most fixing pipe that are connected with first piston and be arranged on the time-delay mechanism in vertical lifting pipe.The upper end of the most fixing pipe is provided with dodges through hole 12.Vertical lifting pipe is coaxially disposed with the most fixing pipe.
The upper end of vertical lifting pipe is through dodging through hole and being positioned at above the most fixing pipe.The upper end closed of vertical lifting pipe.On vertical lifting pipe and be positioned at vertically fixing pipe and be arranged over fire coupling 3, the number of the fire coupling of the present embodiment is one.The lower end of vertical lifting pipe is down through first piston, and the lower ending opening of vertical lifting pipe.Vertical lifting pipe is sealedly and fixedly connected with first piston.It is not arranged over fall way limited block 2 with the most fixing pipe on vertical lifting pipe lateral surface, and fall way limited block is positioned at below fire coupling.
Self adaptation mechanism for opening/closing includes being arranged on vertically fixing manages interior and is positioned at the vertically guide pin bushing 6 of first below vertical lifting pipe, is slidably arranged on the first guide rod 7 of the first vertical guide pin bushing and is arranged on the first guide rod the spool 5 for controlling vertical lifting pipe on/off.First vertical guide pin bushing is connected with the most fixing pipe by head rod.Spool is positioned at the top of the first vertical guide pin bushing.On first guide rod lateral surface and be positioned at below the first vertical guide pin bushing and be provided with the first guide rod limited block 10.Spool is coaxial with vertical lifting pipe.Spool can be moved to vertical lifting pipe by the lower port of vertical lifting pipe.Vertically fix on pipe lateral surface and be positioned at below the first vertical guide pin bushing and be provided with water inlet 14 and discharge outlet 11.Water inlet is provided with water inlet switch valve 15.Discharge outlet is provided with drain pipe 9.Discharge outlet is provided with drainage switch valve 8, and specifically, drainage switch valve is arranged on drain pipe.
As shown in Figure 1 and Figure 2, time-delay mechanism includes the dividing plate 19 being arranged in vertical lifting pipe, the vertical conduit 17 being arranged on dividing plate, the second piston 18 being slidably arranged in vertical conduit, is arranged in vertical lifting pipe and is positioned at second above vertical conduit vertically guide pin bushing 22, the second guide rod 20 being slidably arranged on the second vertical guide pin bushing and the pretension compression spring 21 being set on the second guide rod.Vertically conduit is positioned at the top of spool.Vertically the upper port of conduit is positioned at above dividing plate, and lower port is positioned at below dividing plate.Vertically the length of conduit is less than the spacing between vertical conduit and the second vertical guide pin bushing.Second vertical guide pin bushing is connected with vertical lifting pipe by the second connecting rod.On second guide rod lateral surface and be positioned at the second vertical guide pin bushing and be arranged over the second guide rod limited block 23.Pretension compression spring is vertical between guide pin bushing and the second piston second.When the second guide rod limited block is resisted against on the second vertical guide pin bushing, the second piston is positioned at vertical conduit and near vertical conduit lower end.
As it is shown in figure 1, when fall way limited block is resisted against the outer end face of the most fixing pipe, spool is positioned at vertical lifting pipe and blocks the lower port of vertical lifting pipe.
When first piston is resisted against the inner top surface of the most fixing pipe, spool is positioned at the lower section of vertical lifting pipe.
The specifically used process of the portable underground hydrant of the present embodiment is as follows:
As it is shown in figure 1, portable underground hydrant is installed to underground, the import of water inlet pipe 16 with water inlet switch valve is connected.
During use: fire fighter is by water inlet switch valve opening, water in water inlet pipe enters in the most fixing pipe, then, vertical lifting pipe is driven to rise by first piston under hydraulic pressure effect, during vertical lifting pipe rises, when moving to above earth's surface on fire coupling, fire fighter just can start to install fire hose on the ground, is docked with fire coupling rapidly by fire hose coupling before spool separates with vertical lifting pipe.
On the other hand, during vertical lifting pipe rises, also band movable valve plug and the first guide rod together being risen, when the first guide rod limited block is resisted against on the first vertical guide pin bushing, spool and the first guide rod stop rising；And first piston also will drive vertical lifting pipe to continue to rise, till first piston is resisted against the inner top surface of the most fixing pipe, now spool is positioned at the lower section of vertical lifting pipe.When spool is positioned at the lower section of vertical lifting pipe, the water in the most fixing pipe will enter vertical lifting pipe, thus up be elapsed by the second piston of time-delay mechanism and make the second piston move above vertical conduit.When the second piston moves to after above vertical conduit, and the water in the most fixing pipe through vertical conduit and is entered fire hose by fire coupling；Thus the underground hydrant of the present invention has only to open this valve of water inlet switch valve when actually used, just can realize vertical lifting pipe to rise, facilitate fire fighter that fire hose (need not extra power-equipment) is installed on the ground, and automatically supply water for fire hose within following a period of time.
After portable underground hydrant has used, close water inlet switch valve, opening water discharge controlled valve；Now, the second guide rod and the second piston is made to move down reset under the effect of pretension compression spring, until the second guide rod limited block is resisted against second vertically leads slipped-on position；Then, the pressure of vertical lifting pipe being resetted, be resisted against until fall way limited block till vertically fixing on the outer end face of pipe, now, spool is positioned at vertical lifting pipe and blocks the lower port of vertical lifting pipe；Followed by, close drainage switch valve.
