Fig. 3 is the structural schematic diagram of secondary bolt of the invention；
Fig. 4 is the partial enlarged view in Fig. 1 at A.
Specific embodiment
As shown in Figure 1-Figure 3, this cascade fire hydrant, including king bolt 11 and secondary bolt 1, king bolt 11 are installed on first base
In body 14, secondary bolt 1 is installed in second matrix 2, and the first matrix 14 and the second matrix 2 are embedded in the soil, and the first base
Body 14 and the upper surface of the second matrix 2 are concordant with ground；
Specific structure is described in detail below, wherein the first, second intrinsic silicon opens up the water inlet of upper surface opening
Plate 16 sealing together is welded in the bottom of chamber 17, secondary bolt 1 and king bolt 11, and the outer wall of sealing plate 16 wraps up one layer of layer of silica gel (not
Diagram), sealing plate 16 is sealed by external layer of silica gel and 17 inner wall of intake antrum, and the top of secondary bolt 1 and king bolt 11 is protruded
In the top upper surface of the first, second matrix, an opening 12 is respectively formed at the top of the first, second matrix；
A water outlet connector is respectively arranged in the two sides of first matrix 14, and the side of the second matrix 2 faces water outlet connector setting
There is a water supply connector, an aqueduct 23, the water supply connector input of the second matrix are all connected between water outlet connector and water supply connector
End is provided with an intake tunnel 33, and a water outlet 34, water outlet 34 and the second matrix 2 is arranged in the output end of intake tunnel 33
Internal intake antrum communicates；
One is provided among the sealing plate of 11 bottom of sealing plate 16 and king bolt of secondary 1 bottom of bolt to communicate with body
The bottom water inlet of water inlet (not shown), the sealing plate 16 of secondary 1 bottom of bolt welds a metal block, between secondary bolt 1 and king bolt 11
It is additionally provided with one and pushes the mechanism that blocks water.
In the present embodiment, pushes the mechanism that blocks water and be installed in 14 bottom cover plate 22 of the first matrix, cover board 22 is close by screw thread
It seals in the bottom thread mouth of the first matrix 14, a main water inlet tube 19 is accessed in the bottom of cover board 22, and main water inlet tube 19 accesses outside
High-pressure water.
Pushing the mechanism that blocks water includes a connecting tube 5 and the piston rod 4 for being weldingly fixed on metal block bottom, and connecting tube 5 is buried
Enter in soil, connecting tube 5 is L-shaped, is provided with a conduit pipe 6 among it, fills full water, piston in conduit pipe 6
The bottom of bar 4 is provided with sealing-plug 7, and piston rod 4 is inserted in conduit pipe 6 from top sealing and is sealed by sealing-plug 7
Conduit pipe, the output end of conduit pipe 6 are communicated with the main intake tunnel 21 inside main water inlet tube.
As shown in figure 4, a rubber elastic membrane 51, elastic rubber is arranged in the junction of conduit pipe 6 and main intake tunnel 21
A motion stops 52 are arranged in the inner end of the output end in 51 sealing ventilation channel of film, rubber elastic membrane 51, and motion stops 52 seal entirely
Conduit pipe 6.
A metallic packing ring 15 is welded and fixed in the intake antrum of first, second intrinsic silicon, is set among metallic packing ring 15
Set the through-hole passed through for body, through-hole outer diameter is equal to the outer diameter of king bolt 11 and secondary bolt 1, king bolt 11 and pair bolt 1
Outside be set with one group of reset spring 13, the top of reset spring 13 and the top surface of intake antrum 17 are welded and fixed, bottom with
The upper surface of metallic packing ring 15 is welded and fixed, and the water outlet of king bolt 11 and secondary bolt 1 stretches out in outside.King bolt 11 and pair
Bolt 1 can opposing metallic sealing ring make oscilaltion movement, when king bolt or secondary bolt are pressurized, reset spring can be stretched,
At this time body can equal retraction in intake antrum, to avoid directly hitting, therefore the external extension elongation of fire hydrant of the invention is not
It is preferably excessively high, as long as water inlet is exposed, and the top of fire hydrant is arc surface, facilitates shock to squeeze, high-pressure water can not
Disconnected to jack up king bolt and secondary bolt outward, reset spring plays the function of limit compression.
When king bolt is hit, king bolt can decline retraction in intake antrum, when king bolt drops to bottommost, king bolt bottom
The water inlet in portion can be directly with the output end Butt sealing of main intake tunnel, the aqueduct be connected originally with two sides pair bolt at this time
Input terminal water source is blocked, and can only be discharged at this time from king bolt, cannot be discharged from secondary bolt, in this case it is possible to prevente effectively from because
King bolt is hit and other secondary bolts have probability to be hit and the case where water spray occur, and we can be to cascade with it after pushing king bolt
Secondary bolt is overhauled, very convenient, while king bolt can also continue use of supplying water.
It is compressed into when in intake antrum when one of secondary bolt is knocked down, piston rod declines at this time, squeezes conduit pipe
In air so that motion stops are mobile towards rubber elastic membrane, elastic rubber membrane swelling, motion stops enter main intake tunnel
In, main intake tunnel narrows at this time, and water yield reduces, and reduces water yield with its cascade each body at this time.It is this cascade
Structure to produce the relationship to interact between each fire hydrant, in the switch that remotely can control corresponding body
Water, and can cut off the water supply after any one body is hit retraction, facilitate the maintenance between cascade each body, also increases
After one of body is hit, the safeties of other several bodies, as long as secondary bolt is pressed down, then near cascade therewith
Several bodies can immediately cut off the water supply, and there will not be the case where water source sprays even if being hit.
As long as can block others are several to disappear the beneficial effects of the present invention are: the present invention pushes any one fire hydrant
The water source of anti-bolt, therefore after one of fire hydrant is by drops, the water source with its cascade several fire hydrant can be closed,
And can avoid vehicle after pushing and be knocked, fire hydrant is effectively protected, anti-collision effect greatly promotes.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, of the invention
Protection scope should be determined by the scope of protection defined in the claims.
