Description

Technical Field

[0001] The utility model relates to the technical field of pipeline leakage blocking, in particular to an emergency blocking device for oil pipeline leakage. Background Art

[0002] Oil pipeline leakage not only causes waste of resources, but also poses a great safety hazard. Therefore, it is necessary to seal the leaking points of the pipeline. Among them, the strong injection method is a common method for sealing pipeline leaking points. Specifically, a sealing cavity is prefabricated at the leaking point or the leaking point itself has a sealing cavity. The sealing rubber is forcefully injected into the sealing cavity and quickly solidifies into a new filler to block the leaking part. It is suitable for high-pressure, high-temperature, flammable and explosive parts that are difficult to seal.

[0003] After searching, a Chinese patent provides a device for sealing leakage points in oil and natural gas pipelines, with the publication number CN218719700U, which includes two arc-shaped plates, which are symmetrically matched to form a ring body that is close to the pipeline to be sealed. The inner side of the arc-shaped plate is provided with a groove that is close to the pipeline to be sealed, and multiple partition plates are equidistantly constructed in the groove.

[0004] The above-mentioned device for sealing leakage points of oil and gas pipelines, thanks to the cooperation between the arc plate and the partition plate, divides the groove in the arc plate into multiple sealing chambers, so that when the staff seals the leakage points of the pipeline, they only need to inject sealant into the sealing chambers at specific positions, which is convenient to use;

[0005] However, the method of sealing the outside of the leakage hole with sealant has a relatively simple structure. Under the impact and pressure of the fluid in the pipeline, the sealant is prone to penetration at the joint, and the anti-displacement ability after sealing is poor. The outer shell is easily impacted and slipped, affecting the sealing stability. Utility Model Content

[0006] The purpose of the utility model is to provide an emergency plugging device for oil pipeline leakage, which can effectively solve the problems in the background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] An emergency plugging device for leaks in a petroleum pipeline comprises a sealing assembly disposed at a leak hole in the pipeline body, the sealing assembly comprising two sealing sleeves connected to each other by connecting bolts disposed on both sides, and a mounting seat disposed at the center of the top end of one of the sealing sleeves;

[0009] The upper and lower ends of the mounting seat are threadedly connected with mounting posts, and a sealing rubber pad is provided at the lower position of the outer ring of the mounting post. The two sealing sleeves are combined into a circular ring arrangement, and a number of equidistantly arranged partitions are fixedly connected inside the two sealing sleeves. A glue injection head is provided on the outer ring of the sealing sleeve and located between each two mounting seats, and a glue injection hole is provided at the connection between the sealing sleeve and the glue injection head.

[0010] Preferably, the bottom end of the mounting column is threadedly connected to an insert rod, and the bottom end of the insert rod is fixedly connected to a rubber arc block.

[0011] Preferably, the sealing rubber pad and the rubber arc block are both softly configured, and the rubber arc block is semicircularly configured with the opening facing upward.

[0012] Preferably, the front and rear ends of the sealing rubber pad are inclined, and the top surface of the sealing rubber pad fits against the inner wall of the conveying pipe body when the sealing rubber pad is unfolded.

[0013] Preferably, the front and rear ends of the two sealing sleeves are connected to anti-slip rubber sleeves, and the opposite surfaces of the anti-slip rubber sleeves are in contact with the outer ring of the conveying pipe body.

[0014] Preferably, a rotating handle is fixedly connected to the top end of the mounting column, and a sealing plug is threadedly connected to the end of the glue injection head away from the sealing sleeve.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model sets a sealing component to cooperate with the conveying pipe body. When injecting glue to seal, the sealing rubber pad is inserted into the leakage hole of the conveying pipe body and unfolded. The leakage hole can be initially blocked from the inside, and the external injection sealing method is combined to achieve a double blocking effect, thereby reducing the probability of leakage at the connection and improving the sealing effect.

[0017] 2. The rubber arc block, mounting column and anti-slip rubber sleeve cooperate with each other. After sealing, the mounting column and the insertion rod are inserted into the leakage hole and the inside of the conveying pipe body, and the anti-slip rubber sleeve is sleeved on the outer ring of the conveying pipe body. This can reduce the probability of the sealing sleeve being displaced due to collision. The rubber arc block is set as a semicircular arc. When fluid remains in the conveying pipe body, the rubber arc block can be pressed to limit the upward movement of the insertion rod, thereby improving the sealing stability.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] Combine Figure 1-Figure 3 A device for sealing oil pipeline leakage emergency, comprising a sealing assembly 2 arranged at a leakage hole of a pipeline body 1, wherein the sealing assembly 2 has two sealing sleeves 3, and the two sealing sleeves 3 are connected to each other by connecting bolts 12 arranged on both sides, and a mounting seat 4 is arranged at the center of the top end of one of the sealing sleeves 3.

[0025] like Figure 2 and Figure 3 As shown, it is further obtained that the upper and lower ends of the mounting seat 4 are threadedly connected with a mounting column 5, the outer ring of the mounting column 5 is provided with a sealing rubber pad 6 at the lower position, the two sealing sleeves 3 are combined into a circular ring arrangement, and the two sealing sleeves 3 are fixedly connected to a number of equidistantly arranged partitions 10, the outer ring of the sealing sleeve 3 and between every two mounting seats 4 are provided with a glue injection head 11, and a glue injection hole is provided at the connection between the sealing sleeve 3 and the glue injection head 11, the top of the mounting column 5 is fixedly connected with a rotating handle 9, and the end of the glue injection head 11 away from the sealing sleeve 3 is threadedly connected with a sealing plug.

[0026] Specifically, the sealing sleeve 3 can be fixed to the conveying pipe body 1 by aligning the two sealing sleeves 3 and tightening the connecting bolts 12. When fixing, the sealing rubber pad 6 below the mounting column 5 can be folded, and after the sealing rubber pad 6 is inserted into the conveying pipe body 1, the sealing rubber pad 6 can be loosened, so that the sealing rubber pad 6 is expanded at the leakage hole in the conveying pipe body 1. At the same time, the rubber arc block 8 is installed below the mounting column 5 through the insertion rod 7. The rubber arc block 8 can be inserted into the interior of the conveying pipe body 1 while the sealing rubber pad 6 is installed. After the rubber pad 6 is fully unfolded, glue can be injected toward the outside of the appropriate conveying pipe body 1 through the glue injection head 11 to seal the leakage hole and the cracks around it. Through the above steps, the leakage hole of the conveying pipe body 1 can be sealed from the inside and the outside, which can reduce the probability of leakage and improve the sealing effect. At the same time, when the sealing rubber pad 6 and the rubber arc block 8 are inserted, the leakage hole can be enlarged with the help of tools according to actual needs to ensure that the sealing rubber pad 6 can be smoothly inserted, and through appropriate enlargement, the leakage hole can be adjusted to a regular shape to reduce the probability of leakage.

[0027] Example 2

[0028] like Figure 2 As shown, and on the basis of Example 1, it is further obtained that the bottom end of the mounting column 5 is threadedly connected to the insertion rod 7, the bottom end of the insertion rod 7 is fixedly connected to the rubber arc block 8, the sealing rubber pad 6 and the rubber arc block 8 are both soft settings, and the rubber arc block 8 is a semicircular setting with the opening facing upward, the front and rear ends of the sealing rubber pad 6 are inclined, and when the sealing rubber pad 6 is unfolded, the top surface is in contact with the inner wall of the conveying pipe body 1, and the front and rear ends of the two sealing sleeves 3 are connected to the anti-slip rubber sleeves 13, and the opposite surface of the anti-slip rubber sleeves 13 is in contact with the outer ring of the conveying pipe body 1.

[0029] Specifically, by cooperating with the mounting post 5 and the sealing rubber pad 6 to stick to the inner wall of the conveying pipe body 1, and cooperating with the anti-slip rubber sleeve 13 to be sleeved on the conveying pipe body 1 from the outside, the friction between the sealing sleeve 3 and the conveying pipe body 1 can be improved, and the probability of the sealing sleeve 3 being collided and skewed after the injection sealing is reduced. At the same time, the insertion rod 7 is inserted into the interior of the conveying pipe body 1, and a semicircular rubber arc block 8 is connected to the bottom of the insertion rod 7. When the conveying pipe body 1 is filled with fluid, the rubber arc block 8 is in the fluid, which can limit the insertion rod 7 from detaching upward, thereby pulling the mounting post 5 to reduce the probability of the sealing sleeve 3 detaching. At the same time, when the sealing rubber pad 6 is subjected to the fluid pressure in the conveying pipe body 1, the gap between it and the conveying pipe body 1 will be reduced, further improving the sealing effect.

[0030] In actual operation, the sealing sleeves 3 can be fixed to the conveying pipe body 1 by aligning the two sealing sleeves 3 and tightening the connecting bolts 12. When fixing, the sealing rubber pad 6 below the mounting column 5 can be folded. After the sealing rubber pad 6 is inserted into the conveying pipe body 1, the sealing rubber pad 6 can be loosened, so that the sealing rubber pad 6 is unfolded at the leakage hole in the conveying pipe body 1. At the same time, the rubber arc block 8 is installed below the mounting column 5 through the insertion rod 7. The rubber arc block 8 can be inserted into the interior of the conveying pipe body 1 while the sealing rubber pad 6 is installed.

[0031] After the sealing rubber pad 6 is fully expanded, glue can be injected into the appropriate sealing sleeve 3 through the glue injection head 11 to seal the leakage hole and the cracks around it. Through the above steps, the leakage hole of the conveying pipe body 1 can be sealed from the inside and outside, which can reduce the probability of leakage and improve the sealing effect. At the same time, when the sealing rubber pad 6 and the rubber arc block 8 are inserted, the leakage hole can be expanded with the help of tools according to actual needs to ensure that the sealing rubber pad 6 can be smoothly inserted. By appropriately expanding the hole, the leakage hole can be adjusted to a regular shape to reduce the probability of leakage.

[0032] By cooperating with the mounting post 5 and the sealing rubber pad 6 to stick to the inner wall of the conveying pipe body 1, and cooperating with the anti-slip rubber sleeve 13 to be sleeved on the conveying pipe body 1 from the outside, the friction between the sealing sleeve 3 and the conveying pipe body 1 can be improved, and the probability of the sealing sleeve 3 being collided and skewed after the injection sealing is reduced. At the same time, the insertion rod 7 is inserted into the interior of the conveying pipe body 1, and a semicircular rubber arc block 8 is connected to the bottom of the insertion rod 7. When the conveying pipe body 1 is filled with fluid, the rubber arc block 8 is in the fluid, which can limit the insertion rod 7 from detaching upward, thereby pulling the mounting post 5 to reduce the probability of the sealing sleeve 3 detaching.
