Abstract

The utility model relates to a blocking oil well fire extinguishing device, which is suitable for fire extinguishing of the oil well of land oilfields. The surroundings of a combustion oil well are laid with parallel double guide rails to support the well plug frame of steel structure which can move on the guide rails. Besides, the well plug frame is arranged on the guide rails. The top beam of the well plug frame is hung with a column well plug with a cone head. An explosive cylinder which is installed on the tail part of the well plug supports the double guide rails which are arranged in the middle part of the well plug frame. Besides, the outer side of the explosive cylinder is respectively provided with pressure, two movable cover plates of a spring and two parallel spacing plates which are arranged between the two movable cover plates. The blocking oil well fire extinguishing device can directly block oil well fire sources and insulate the contact of the oil surface of the fire sources and air. The blocking oil well fire extinguishing device has the advantage of high fire extinguishing efficiency. Besides, the blocking oil well fire extinguishing device has no need to consume fire extinguishing materials.

Description

Blocking oil well fire extinguishing device

The utility model relates to a kind of oil well fire-extinguishing equipment, and it is applicable to the oil well in oil field, land Fire extinguisher on fire.

At present, the oil well in oil field, land is on fire, just adopts the fire-extinguishing apparatus with extinguish materials such as water, carbon dioxide foaming, sands, and in fact, to the oil field big fire of intensity of a fire ferociousness, the fire-extinguishing apparatus that sprays above-mentioned extinguish material has not had Ji as thing.

In view of this, the purpose of this utility model provides a kind of blocking type oil well fire-extinguishing device, it is a strength of utilizing the grain blast, promote the metal hole plug, pour the oil well that is burning at a high speed, make pasta and two removable covers under the vibrations of blast of isolated while of air of oil well draw close, cover well head, further seal well mouth of oil well, force the oil well fray-out of flame.

The purpose of this utility model is achieved in that lays parallel two guide rails around the oil well of burning, the steel work hole plug frame that is supported on the guide rail and can moves thereon, hole plug frame back timber hangs the cylinder hole plug of a band conehead down, be contained in the grain of hole plug afterbody, be supported on the middle two guide rails of hole plug frame, and pressure is arranged, two removable covers of spring, and two parallel interval plates between two removable covers respectively in the outside.

Owing to adopt such scheme, can directly stop up the oil well burning things which may cause a fire disaster, the pasta of isolated burning things which may cause a fire disaster contacts with air, than the extinguishing device fire-fighting efficiency height of prior art, and is the direct fire extinguishing that does not need to consume extinguish material.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the front schematic view of embodiment of the present utility model.

Fig. 2 is the A-A sectional view among embodiment Fig. 1 of the present utility model.

Among the figure: 1. pair guide rail, 2. hole plug frame, 3. grain, 4. hole plug, 5. removable cover, 6. space bar.

In Fig. 1 and 2 illustrated embodiment, two guide rails 1 are the i iron guide rails, be placed on around the oil well of burning, the hole plug shelf is the steel work ladder frame, 4 vertical beams support the weight of whole hole plug frame 2 on two guide rails 11, and the roller that can roll is equipped with in the bottom of 4 vertical beams on two guide rails, and the end face crossbeam has the hook that hangs hole plug 4.Hole plug 4 is the cone headed cylinders of steel band, at hole plug 4 afterbodys grain 3 is housed, comprise high explosives in the grain 3, two parallel rectangular removable covers 5 are supported on two guide rails 1 of hole plug frame 2 centres, in two removable covers, 5 outsides compression spring is arranged respectively, can promote two removable covers 5 and on two guide rails 1, slide and draw close, between two removable covers 5, place two parallel space bars 6.

The using method of present embodiment is as follows:

At first dragging hole plug frame 2 rolls on two guide rails 1, be in the oil well position of burning until hole plug frame 2, light the grain 3 of hole plug 4 afterbodys with lead-in wire, grain 3 blasts, promoting hole plug 3 flings into deep-well depths pasta, stop up oil well, simultaneously, the vibrations that grain 3 blasts produce vertically change the spring in two removable cover 5 outsides, when contract in the spring field, two interblock dividing plates 6 drop, and spring promotes two removable covers 5 at once and draws close, and just in time covers the well mouth of oil well of burning, make the pasta and the air of burning further isolated, fire slowly extinguishes naturally.

Claims

A kind of blocking type oil well fire-extinguishing device, it is characterized in that: around the oil well of burning, lay parallel two guide rails 1, the steel work hole plug frame 2 that is supported on the guide rail 1 and can moves thereon, hole plug frame 2 back timbers hang the cylinder hole plug 4 of a band conehead down, be contained in the grain 3 of hole plug afterbody, be supported on two guide rails 1 of hole plug frame 2 centres, and pressure is arranged respectively in the outside, two removable covers 5 of spring, and two parallel interval plates 6 between two removable covers 5.
