Abstract

The utility model relates to a pollution-prevention cofferdam for an oil pipe bed, which comprises PVC plastic cofferdam boards, PVC plastic cofferdam corners, a PVC plastic buckle, bolts and a plastic cloth inner liner. The utility model is characterized in that the cofferdam is a rectangular block enclosed by a plurality of cofferdam boards and four cofferdam corners, and the perimeter of the rectangular block is greater than that of the oil pipe bed; each cofferdam board is an isosceles trapezoid body or right-angle trapezoid body; each buckle is an isosceles or right-angle trapezoid body, the upper bottom and the lower bottom are smaller than the upper bottom and the lower bottom of the cofferdam boards, the buckles are buckled in the cofferdam boards, one end of each cofferdam board is only buckled with one projecting buckle, the buckles are fixed to the cofferdam boards by the screws, and the buckle of one cofferdam board and the end of another cofferdam board without the buckle constitute a burrock; one end of each cofferdam corner is buckled with the same buckle, and the buckle is buckled with the cofferdam board to constitute the cofferdam; and the cofferdam is lined with the plastic cloth inner liner internally. The utility model solves the problem of environmental pollution caused by dripping oil of the oil pipes.

Description

The anti-pollution cofferdam of oil pipe bed

One, technical field

When the utility model relates to a kind of workover treatment, prevent that the inside and outside sump oil sewage of oil pipe on the oil pipe bed from immersing the earth or the excessive outer environmental protection dike that spatters, the anti-pollution cofferdam of specifically a kind of oil pipe bed.

Two, background technology

At present, during oil well repairing operation, be to impale an earth embankment with around the tubing rack, prevent that the sump oil sewage outflow from spattering the expansion contaminated area outward, play certain environmental-protection function, but do not prevent land pollution.This indigenous method implements very difficult winter, digs big, time-consuming, the effort of frozen soil embankment labour intensity, does not fundamentally also have the effect of sump oil sewage to land pollution that prevent, does not also meet the requirement of carrying out production strictly in line with rules and regulations.

Three, summary of the invention

The purpose of this utility model provides the anti-pollution cofferdam of a kind of oil pipe bed, overcomes the defective of above-mentioned prior art, fundamentally solves the problem of the sump oil sewage pollution the earth on the oil pipe.

The technical solution of the utility model realizes in the following manner:

The utility model is made up of PVC plastics cofferdam plate, angle, PVC plastics cofferdam, PVC plastics attacker, screw and Polypropylence Sheet neck bush, it is characterized in that the cofferdam is made as the cuboid that is surrounded by some blocks of cofferdam plates and angle, four cofferdam, and its girth is greater than the girth of oil pipe bed; The cofferdam plate is made as isosceles trapezoid body or right-angled trapezium body; The attacker is made as isosceles or right-angled trapezium body, its upper base and going to the bottom less than the upper base on the plate of cofferdam and going to the bottom, be buckled within the plate of cofferdam, one end of every block of cofferdam plate is only detained the attacker of a protrusion, be screwed the end that the attacker of a cofferdam plate and another piece cofferdam plate do not have the attacker composition burrock that interlocks between attacker and the cofferdam plate; Each angle, cofferdam one end is buckled with same attacker equally, interlocks with the cofferdam plate and forms the cofferdam; Be lined with the Polypropylence Sheet neck bush in the cofferdam.

Compared with the prior art the utility model has the following advantages:

1, cofferdam plate and angle, cofferdam PVC material compression molding, intensity is big, good toughness, and is not fragile, reusable.

2, Polypropylence Sheet neck bush and cofferdam match, and elegant in appearance neat, disposable use can be poured greasy dirt in the container into and be transported, and the Polypropylence Sheet neck bush reclaims.

3, the use in cofferdam has prevented the pollution of sump oil sewage to the earth and environment, guarantees the cleaning of workover treatment environment.

Five, the specific embodiment

For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:

The utility model is made up of angle, PVC plastics cofferdam 1, PVC plastics cofferdam plate 2, PVC plastics attacker 3, screw 4 and Polypropylence Sheet neck bush, it is characterized in that the cofferdam is made as the cuboid that is surrounded by some blocks of cofferdam plates and angle, four cofferdam, its girth is greater than the girth of oil pipe bed; Cofferdam plate 2 is made as isosceles trapezoid body or right-angled trapezium body; Attacker 3 is made as isosceles or right-angled trapezium body, its upper base and going to the bottom less than the upper base on the plate of cofferdam and going to the bottom, be buckled within the plate of cofferdam, one end of every block of cofferdam plate is only detained the attacker of a protrusion, be screwed the end that the attacker of a cofferdam plate and another piece cofferdam plate do not have the attacker composition burrock that interlocks between attacker and the cofferdam plate; Each angle, cofferdam one end is buckled with same attacker equally, interlocks with the cofferdam plate and forms the cofferdam; Be lined with the Polypropylence Sheet neck bush in the cofferdam. in the cofferdam, install tubing rack, being placed on the oil pipe bed of one one in the oil pipe that will trip out in the well, oil that oil pipe is taken out of or sewage all drop on or spatter in the Polypropylence Sheet neck bush, repair after the completion Deng having removed oil pipe, the oil pipe bed of dismantling is poured the profit in the Polypropylence Sheet lining into and is pulled away in the uncovered oil tank, reclaim the Polypropylence Sheet neck bush, focus on, the dismounting cofferdam is pulled away and is kept, and waits next well workover to use.
