Abstract
Disclosed is a safe vertical type underground fire hydrant. According to the safe vertical type underground fire hydrant, a fire hydrant body is arranged underground and meanwhile and fixed onto a support jack. A firefighter can open a cover plate above a protecting case, then rotate a second screw through a rotating tool, and lastly drive the top support seat of the support jack up through the first screw, and when the top support seat moves to the top end, the height of a water outlet is higher than the ground, so that the firefighter can connect a fire hose with the water outlet of the fire hydrant in butt joint without going underground; meanwhile, the top of the fire hydrant body is provided with a pressure meter, so that the firefighter can observe the internal pressure condition of the fire hydrant at any time, and once finding numerical value abnormality during daily maintenance, can instantly performing corresponding maintenance on the fire hydrant to ensure smooth rescue when abrupt fire breaks out. The safe vertical type underground fire hydrant is integrally in pure mechanical connection, thereby enhancing the systemic reliability and avoiding the problem of possibly-existing circuit disconnection due to electric lifting of the fire hydrant body.
Description
Technical field

Detailed description of the invention
Embodiment 1
As shown in the structural representation of the present invention of Fig. 1, the vertical underground hydrant of safety comprises the protective housing 5 being positioned at underground, and be placed in the fire hydrant body 1 of vertical in protective housing 5, fire hydrant body 1 side-walls is distributed with water inlet 2, delivery port 3, valve 4, be fixed in support jack 8 top support bottom fire hydrant body 1, the base of support jack 8 is fixed at the bottom of the case of protective housing 5, first screw rod 9 one end of support jack 8 is connected in two regulating sleeves in the middle part of support jack 8 successively, first screw rod 9 other end is in transmission connection by steering spindle 10 and the second screw rod 11, second screw rod 11 extends to the top position of protective housing 5, the water inlet 2 of fire hydrant body 1 is connected with feed water inlet 6 by flexible pipe 7, fire hydrant body 1 top layout has pressure gauge 12.
Support jack 8 is existing application in other field, does not describe in detail at this, and it is by the first screw rod 9 in rotation two regulating sleeves, can mutual alignment between regulating sleeve, thus the top support of support jack 8 is propped up by upper and lower two groups of support bars.
Water inlet 2 is positioned at fire hydrant body 1 sidewall lower position, and delivery port 3 and valve 4 are positioned at the relative position above fire hydrant body 1 sidewall.
Along concordant with ground on protective housing 5, protective housing 5 upper opening is provided with cover plate 13, and cover plate 13 corresponding pressure meter 12 place is observation port 14, and observation port 14 is transparent configurations of tempered glass.
During support jack 8 full extension, the level height of fire hydrant body 1 upper water-out mouth 3 is above the ground level highly.
Feed water inlet 6 extends in protective housing 5 through protective housing 5 sidewall, flexible pipe 7 length connected between feed water inlet 6 and water inlet 2 is greater than the distance after support jack 8 full extension between feed water inlet 6 and water inlet 2, guarantees that fire hydrant body 1 is still connected by flexible pipe 7 between water inlet 2 with feed water inlet 6 after rising.
Be connected to bottom second screw rod 11 in steering spindle 10, its top layout has screw rod to extend mouth 15, the output of throw can be snapped fit onto screw rod to extend in mouth 15, thus fire hydrant body 1 be propped up by tool drives support jack 8, wherein throw is motor or extends screw rod.
During use, after fire fighter opens the cover plate above protective housing 5, the output of throw is extended mouth 15 with the screw rod of the second screw rod 11 dock, start throw, as opened motor or hand rotation prolongation screw rod, the second screw rod 11 is driven to rotate, second screw rod 11 through steering spindle 10 by transmission direction by the first screw rod 9 vertically going to horizontal direction, the top support of final driving support jack 8 rises, the height rising to delivery port 3 during top is above the ground level, therefore fire hose can dock with the delivery port 3 of fire plug without the need to entering underground by fire fighter, also because entirety all adopts pure mechanical connection, add the reliability of system, avoid the Circuit Interrupt problem that may exist in electronic rise fire hydrant body 1.
Because its water inlet 2 is connected with feed water inlet 6 by longer flexible pipe 7 in the process that fire hydrant body 1 rises, therefore can not affect fire plug and supply water.
Also because in fire hydrant body 1 top layout pressure gauge 12, cover plate corresponding pressure meter 12 place is the transparent configuration of tempered glass simultaneously, therefore, it is possible to observe pressure condition in this fire plug at any time, at ordinary times in maintenance process once find numerical exception, at once corresponding maintenance is carried out to this fire plug and guarantees to rescue smoothly when there is burst fire.
Embodiment 2
As shown in Figure 2, the present embodiment is substantially identical with embodiment 1 structure, difference is that screw rod prolongation mouth 15 place that the second screw rod 11 top connects also is furnished with handwheel 16, when there is no other auxiliary throw, hand rotation handwheel 16 drives the second screw rod 11 to rotate, thus fire hydrant body 1 is risen.
