Abstract
The utility model relates to the technical field of fire hydrants, in particular to an outdoor fire hydrant of a lifting type rotating chamber. The outdoor fire hydrant comprises a rotating hydrant body, a lifting body is arranged at the lower end of the rotating hydrant body, the lifting body is connected through steel balls and sealed through an O-shaped seal ring I, the lower end of the lifting body is sleeved into a middle section and is hermetically connected through a seal ring II, the lower end of the middle section is connected with an elbow, and cavities of the rotating hydrant body, the lifting body, the middle section and the elbow connected together form a water flow channel; a rack is arranged on the middle section, a gear box is arranged on the lifting body, a transmission gear, a big gear and a control gear are installed in the gear box, the control gear is meshed with the big gear, a shaking hand wheel is connected on the control gear, and one end off the rack extends to be connected with the transmission gear. Because the structure is arranged, the outdoor fire hydrant of a lifting type rotating chamber can be freely lifted and rotate within a certain range, the height and the direction of a water outlet can be changed, and the outdoor fire hydrant is convenient, practical, safe and reliable.
Description
Technical field
The utility model relates to fire-fighting outdoor fire hydrant technical field, particularly a kind of ascending/decending rotation outdoor fire hydrant.
Background technology
The outdoor fire hydrant of commonly using all is to be fixedly connected on the fire protection pipeline, and the delivery port height is fixed, and can not be elevated to the ideal height of practical operation, and the delivery port direction also is fixed extremely, can not rotate.The hydrant of this structure makes to be installed in road easily. and leak because of hit the fire water that causes by mistake in street or the urban construction, influence the ground environment and the appearance of the city.Deviating from the therefore dead pleat of water band meeting that the delivery port direction is connected with certain altitude; The pressure of water can not reach the force value of the needed water of rescue personnel; Can not effectively control hydraulic pressure, can't satisfy rescue personnel's needs, bring very big hidden danger and inconvenience to fire-fighting and rescue.
The utility model content
In order to overcome the above-mentioned weak point that exists in the prior art; The purpose of the utility model is to provide a kind of free lifting within the specific limits and rotation; Can change delivery port height and direction, convenient and practical, safe and reliable ascending/decending rotation outdoor fire hydrant.
In order to reach above-mentioned purpose, the utility model adopts following concrete technical scheme: a kind of ascending/decending rotation outdoor fire hydrant comprises that the lower end of rotation key, rotation key is provided with lifting body; In the joint, the lower end of middle joint was connected with elbow during be inserted in the lower end of lifting body, and the rotation key that links together, lifting body, middle joint and elbow inner chamber constitute a water stream channel; Joint is provided with tooth bar in said; Said lifting body is provided with gear-box, and travelling gear, gear wheel and control gear are housed in the said gear-box, said control gear and gear wheel engagement; And on control gear, be connected with and shake handwheel, an end of said tooth bar extends to travelling gear and connects.
Be provided with steel ball between the lower end of said rotation key and the upper end of lifting body, and through O RunddichtringO I sealing.
The lower end of said lifting body is nested in the middle joint, and is tightly connected through sealing ring II.
Compared with prior art, the utlity model has following outstanding advantage and effect: the utility model will rotate key and be bumped into lifting body, the structure of joint and the design and installation of jacking equipment during lifting body is inserted in again; Thereby can rotate freely within the specific limits and go up and down, can change delivery port direction and height, the pressure of feed pipe is controlled effectively; Improved fire-extinguishing apparatus and caused unnecessary loss inadequately, also possessed the crashproof function of the formula of hiding in the middle of the while is invisible, under conditions permit, can be loaded on whole hydrant underground because of hydraulic pressure; Well door closure with resistance to compression is light is lived; The water intaking time spent only need be opened Jing Men and shaken the up-down handwheel, key is raised to suitable height gets final product, and falls reposition after having fetched water again; Can avoid mistake to hit the damage that brings, make fire fighting equipment obtain certain protection.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Below in conjunction with accompanying drawing the utility model is done further to specify.
The specific embodiment
As shown in Figure 1, a kind of ascending/decending rotation outdoor fire hydrant comprises that the lower end of rotation key 1, rotation key 1 is provided with lifting body 2; Connect and O RunddichtringO I12 sealing through steel ball 11, save in 3 during be inserted in the lower end of lifting body 2, and be tightly connected through sealing ring II5; The lower end of middle joint 3 is connected with elbow 4, and the rotation key 1 that links together, lifting body 2, middle joint 3 and elbow 4 inner chambers constitute a water stream channel, and said middle joint 3 is provided with tooth bar 6; Said lifting body 2 is provided with gear-box 21, and travelling gear 10, gear wheel 9 and control gear 8 are housed in the said gear-box 21, said control gear 8 and gear wheel 9 engagements; And on control gear 8, be connected with and shake handwheel 7, an end of said tooth bar 6 extends to travelling gear 10 and connects, and rotates the rotation that drives gear wheel 9 through shaking handwheel 7; Gear wheel 9 drives control gear 8 rotations, and control gear 8 drives tooth bar 6 rotations, and tooth bar 6 is installed in lifting body 2 again; Thereby can rotate freely within the specific limits and go up and down, can change delivery port direction and height, the pressure of feed pipe is controlled effectively; Improved fire-extinguishing apparatus and caused unnecessary loss inadequately, also possessed the crashproof function of the formula of hiding in the middle of the while is invisible, under conditions permit, can be loaded on whole hydrant underground because of hydraulic pressure; Well door closure with resistance to compression is light is lived, and the water intaking time spent only need be opened Jing Men and shaken the up-down handwheel, key is raised to suitable height gets final product; Fall reposition after having fetched water again, can avoid mistake to hit the damage that brings, make fire fighting equipment obtain certain protection.
What should explain at last is: above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although the utility model is specified with reference to preferred embodiment; Those of ordinary skill in the art is to be understood that; Can make amendment or be equal to replacement the technical scheme of the utility model, and not break away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
