Abstract

The utility model relates to an anti-freezing fire hydrant. The utility model is mainly characterized in that a fire hydrant extension section (5) is arranged below a fire hydrant head, and the bottom of the fire hydrant is provided with a water outlet pipe (10) which is connected to a water pumping pipe (4) communicated with the ground. In addition, the water outlet pipe (10) of the fire hydrant is orderly connected with a floating ball chamber (9) and a liquid level gauge pipe (12) with an observation window (13). After the fire hydrant with the structure is used, the fire hydrant can completely pump and discharge the accumulated water in the hydrant body on the ground by a water pump at any time to prevent the accumulated water from congealing which influences the normal use of the fire hydrant. The anti-freezing fire hydrant has the advantages of simple structure, low manufacturing cost and convenient installation and construction.

Description

Anti-freezing hydrant

Technical field:

The utility model relates to a kind of fire fighting equipment, especially a kind of anti-freezing hydrant.

Background technology:

What use was maximum at present is that hydrant is placed brick well, this method is owing to sealing problem between the water main line and the brick borehole wall can't solve, underground water will enter along each slit of the brick borehole wall in this well, if to winter hydrant just frozen ice in can't use, also may damage hydrant because of freezing up.Daqing Area in high and cold district, existing a kind of hydrant protection tube is being promoted the use of, and it is to substitute the brick well with the steel tube, and water inlet pipe is welded on the steel cylinder sidewall, has solved the problem that groundwater erosion hydrant, influence are used.Along with the variation of steel market relation between supply and demand, the jumbo rise of price of steel product, the patented product cost heightens, and in addition, because of its overall dimensions are big, installation earth excavation amount is also bigger, and construction cost is higher.

Summary of the invention:

The utility model solves two problems emphatically at the deficiencies in the prior art part: the one, and the antifreeze problem of hydrant; The 2nd, reduce protection tube cost problem.The technical measures that adopt are: be a hydrant lengthening section below the hydrant head, the hydrant bottom has gutter to receive to lead on the drinking-water pipe on ground; Gutter effluxes direction along current, is connected to float chamber, drinking-water pipe, valve, water pump; Drinking-water pipe directly is connected on the bottom of hydrant lengthening section, and valve, water pump, pipe bent position are on the ground; Water pump and water outlet are connected the top that the bottom has the hollow valve rod of opening with bend pipe; The float chamber is connected the bottom of hydrant lengthening section, tape splicing form content gauge pipe in the float chamber through gutter.

Because of setting up the hydrant lengthening section; and increase by a structure of overlapping ponding in the emptying hydrant, and hydrant head exposes on the ground, and tube really can not influence normal use yet because of not needing protection; its advantage is: use, install, safeguard all very convenient, the cost also fire hydrant than other model is low.

Description of drawings:

Fig. 1 is the principle schematic of one of embodiment of the present utility model, and drinking-water pipe 4 is connected on the bottom of float chamber; Fig. 2 is 1/4 ratio chart that dwindles of fire hydrant head I, II; Fig. 3 is two the principle schematic of embodiment; Fig. 4 is three the principle schematic of embodiment; Fig. 5 is another form of structure figure of two of embodiment.

The specific embodiment:

Embodiment 1: look as Fig. 1, it below fire hydrant head II the lengthening section 5 of fire hydrant, that outfall of hydrant bottom is to being circumscribed with gutter 10, the float chamber 9 of dress ball float 8 in being connected to again on the gutter 10, the upper end of float chamber 9 connects form 13 through the position of content gauge pipe 12 more than ground, connect a pole beacon 11 on the ball float 8; pole beacon 11 is in content gauge pipe 12; can move up and down with ball float 8; the top color of pole beacon 11 is darker; be in the form 13, play the effect of indication liquid level.9 bottom is connected with drinking-water pipe 4 in the float chamber, and is connected to valve 3, water pump 2, bend pipe 1.When the top of the pole beacon 11 in finding form 13 is higher, illustrate in the float chamber 9 to have ponding, drive valve 3, boiling water pump 2, pole beacon 11 is resetted get final product to extracardiac pumping.In the utility model, valve rod 7 has the hollow section of opening for the bottom.Fire hydrant, content gauge pipe 12, drinking-water pipe 4 are reinforced muscle and link together.

Embodiment 2 looks as Fig. 3: other structure is identical with embodiment 1, and the water pump 2 of the usefulness of just drawing water directly is connected the upper end of valve rod 7.

Embodiment 3 looks as Fig. 4: other structure is identical with embodiment 1, and just drinking-water pipe 4 directly is connected the bottom of the lengthening section 5 of fire hydrant, does not need through float chamber 9, and role and effect and embodiment 1 are identical.

Fig. 5 is another form of structure of two of embodiment, and its structure is more simple than embodiment 2.

Close the bolt internal valve behind the door through valve rod 7 during actual the use, be filled with ponding in the head and in lengthening section 4 tube chambers, if these ponding are not emptying, will freezing hydrant to freezed in winter, so want emptying, draining front opening valve 3, start water pump 2, till emptying, at this moment delivery port is anhydrous, and the top of pole beacon 11 also should be fallen after rise to the low level of form 13.When regular maintenance, can often observe form, as just needing draining, in order to avoid to freezing hydrant in winter in a high position.

Claims

1, a kind of anti-freezing hydrant; its primary structure is: hydrant is welded on the fire main that crosses the protection tube; and be in the protection tube; it is characterized in that: hydrant head I, be a hydrant lengthening section (5) below the II, on the drinking-water pipe (4) that the hydrant bottom has gutter (10) to receive to lead to ground.
