Description

Technical Field

[0001] The invention belongs to the technical field of drilling engineering equipment, and in particular relates to a pipe and cable branch line glue-filling sealing structure and method. Background Art

[0002] During field operations, equipment connection is usually achieved by setting cables. For distributed equipment in field operations, in order to enhance the mechanical properties of the cables themselves, multiple independent cables can be integrated into the same sheath to form a pipe cable. The pipe cable integrated with multiple cables needs to be split near the equipment wiring part, and the single pipe cable is differentiated into multiple independent cables and connected to the corresponding equipment wiring parts respectively. In order to ensure the normal operation of the pipe cable, the end of the pipe cable, that is, the branching part, needs to be sealed to prevent moisture from entering the pipe cable sheath and soaking the cable for a long time, causing insulation failure.

[0003] The existing pipes and cables generally achieve the purpose of covering the branching part of the pipes and cables by setting an annular glue-filling container at the end of the pipes and cables, and sleeve the annular glue-filling container on the outside of the branching part of the pipes and cables, and then fill the glue into the gap between the glue-filling container and the pipes and cables, so as to achieve the effect of sealing the end of the pipes and cables, i.e. the branching part, by filling the end of the pipes and cables with glue. However, after the branching part of the pipes and cables is covered by filling the glue, the highest height of the glue filling can only be flush with the outer edge of the end face of the glue-filling container. After the glue solidifies, the solidified glue will shrink, so that the height of the whole or local position of the solidified glue will be lower than the outer edge of the end face of the glue-filling container, thereby forming a depression on the end face of the glue-filling container. When performing field operations, if it rains or spray washing operations are performed, the depression on the end face of the glue-filling container is very easy to accumulate water, and the accumulated water is difficult to lose or volatilize. Long-term water accumulation will reduce the insulation capacity of the insulation material on the cable surface, causing the insulation capacity to continue to decline until failure. It may also cause the seal failure at the branching part of the pipe and cable, and water and soluble impurities to enter the pipe and cable sheath. The accumulated water in the sheath is difficult to remove. Long-term immersion of cables in water can cause cable insulation failure, which in turn causes short circuit fires, equipment loss of control and other problems.

[0004] Therefore, the existing pipe and cable branch line sealing method is very easy to accumulate moisture, and the accumulated water can easily cause cable insulation failure, posing a safety hazard. Summary of the invention

[0005] In view of the above problems, the present invention proposes a pipe and cable branch line glue-filling sealing structure and method, comprising:

[0006] A wrapping portion, wherein a wrapping cavity is provided in the wrapping portion and is arranged to wrap around the end of the tube and cable, and a colloid can be placed in the wrapping cavity;

[0007] An extension portion, the extension portion is arranged on the end surface of the wrapping portion, and the extension portion is arranged around the wrapping cavity, and the height of the wrapping cavity can be extended by the extension portion, so that the end surface of the colloid placed in the wrapping cavity can be higher than the end surface of the wrapping portion;

[0008] A drainage channel is provided on the end surface of the wrapping portion so that the water accumulated on the colloid can slide down through the drainage channel.

[0009] In some specific embodiments, the extension portion is a cover body, and both ends of the cover body are opened;

[0010] The cover body is arranged on the end surface of the wrapping portion.

[0011] In some specific embodiments, the wrapping portion includes:

[0012] A cylinder, the inner wall of which encloses the wrapping cavity;

[0013] A ring body, the ring body surrounds the cylinder body and is sleeved on the end of the cylinder body;

[0014] The drainage channel is opened on the end surface of the ring body.

[0015] In some specific embodiments, a drainage groove is provided on the ring body;

[0016] There are a plurality of drainage grooves, which are evenly arranged on the end surface of the ring body, and both ends of the drainage grooves extend along the radial direction of the ring body.

[0017] In some specific embodiments, an arc structure is provided between the drainage groove and the end surface of the ring body.

[0018] In some specific embodiments, the end surface of the ring body is an inclined structure with a high inner side and a low outer side;

[0019] Or, the bottom of the drainage trough is an inclined structure with a high interior and a low exterior;

[0020] Alternatively, the end surface of the ring body and the bottom of the drainage groove are both inclined structures with the inner side higher and the outer side lower.

[0021] In some specific embodiments, the ring body is further provided with an annular groove;

[0022] The annular groove is formed on the end surface of the ring body, and the annular groove is arranged around the wrapping cavity, so that the plurality of drainage grooves can be respectively connected to the annular groove;

[0023] A plurality of drainage grooves are connected to the annular groove to form the drainage channel.

[0024] In some specific embodiments, the cover body is arranged to be retracted upward and inward on a side away from the cylinder body.

[0025] In some specific embodiments, the cover body is detachably connected to the ring body.

[0026] In some specific embodiments, the circumferential dimension of the cover body is matched with the circumferential dimension of the annular groove, so that the side of the cover body can be embedded in the annular groove.

[0027] A method for sealing a pipe and cable branch line by pouring glue based on the same concept, using the pipe and cable branch line pouring glue sealing structure as described in any of the above specific embodiments, is characterized by comprising the following steps:

[0028] The extension part is arranged on the end surface of the wrapping part, and the height of the wrapping cavity is extended by the extension part;

[0029] The colloid is placed in the wrapping part, and the end surface of the placed colloid is made higher than the end surface of the wrapping part through the extension part, so as to leave a shrinkage margin for the colloid after curing;

[0030] The wrapping part is arranged vertically to allow the colloid in the wrapping cavity to solidify;

[0031] After the gel has cured, remove the extension.

[0032] The pipe and cable branch glue-filling sealing structure of the present invention can be arranged on the end of the pipe and cable through the wrapping cavity of the wrapping part. At the same time, the height of the wrapping cavity can be extended through the extension part detachably arranged on the end face of the wrapping part, which is equivalent to expanding the glue-filling space. Then, the height of the filled colloid can be higher than the end face height of the wrapping part through the extension part. Even if the colloid solidifies and shrinks, it is difficult for the colloid to form a depression on the end of the wrapping part, reducing the possibility of moisture accumulation. In addition, a drainage channel is also provided on the end face of the wrapping part. Even if there is moisture on the solidified colloid, when the moisture contacts the end of the wrapping part, it will quickly slide down through the drainage channel, thereby avoiding long-term water accumulation at the contact position between the colloid and the end of the wrapping part and the colloid. The failure of the pipe and cable sealing is avoided, the insulation capacity of the cable itself after the branching is guaranteed, and the probability of insulation failure, short circuit fire, equipment out of control and other problems caused by the failure of the sealing of the branching part of the pipe and cable is reduced.

[0033] The pipe and cable branch line glue filling and sealing method of the present invention has the same beneficial effects as the pipe and cable branch line glue filling and sealing structure described above because it adopts the pipe and cable branch line glue filling and sealing structure described above. The height of the wrapping cavity can be extended by the extension part, which is equivalent to expanding the glue filling space. Furthermore, the height of the filled colloid can be higher than the end face height of the wrapping part by the extension part. Even if the colloid solidifies and shrinks, sufficient shrinkage margin can be reserved for the colloid. After the colloid solidifies, the extension part is disassembled, and the top of the colloid is higher than the end face of the wrapping part, so that the colloid is prevented from forming a depression at the end of the wrapping part, and water accumulation in the depression is avoided, thereby avoiding the cable insulation failure and pipe and cable sealing failure caused by water accumulation, ensuring the insulation capacity of the cable itself after the branch line, and reducing the probability of insulation failure, short circuit fire, equipment loss of control and other problems caused by sealing failure of the branch line of the pipe and cable.

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0042] Reference Figure 1 The present invention provides a pipe and cable branch line glue-filled sealing structure, comprising: a wrapping portion 100 and an extension portion 200. A wrapping cavity for wrapping the end of the pipe and cable is provided in the wrapping portion 100, and a colloid can be placed in the wrapping cavity. The extension portion 200 is arranged on the end face of the wrapping portion 100, and the extension portion 200 is arranged around the axial direction of the wrapping cavity. The height of the wrapping cavity can be extended by the extension portion 200, so that the end face of the colloid placed in the wrapping cavity can be higher than the end face of the wrapping portion 100. A drainage channel 121 is provided on the end face of the wrapping portion 100, so that the moisture accumulated on the colloid can slide down through the drainage channel 121.

[0043] Specifically, the interior of the wrapping portion 100 is hollow, thereby forming a wrapping cavity, and the wrapping portion 100 can wrap the outside of the end of the umbilical cable through the wrapping cavity, and there is a gap between the inner wall of the wrapping cavity and the end of the umbilical cable, and the end of the wrapping portion 100 away from the end of the umbilical cable abuts against the outside of the umbilical cable, and the end of the wrapping portion 100 close to the end of the umbilical cable is provided with an opening. When the wrapping portion 100 wraps the outside of the end of the umbilical cable through the wrapping cavity, the colloid can be filled into the wrapping cavity from the opening side of the wrapping portion 100, that is, in the gap between the inner wall of the wrapping cavity and the end of the umbilical cable. The extension portion 200 is arranged around the axial direction of the wrapping cavity, so that the height of the wrapping cavity can be extended along the axial direction of the wrapping cavity through the inner wall of the extension portion 200, which is equivalent to expanding the glue-filling space, so that the height of the extended wrapping cavity can be higher than the end face height of the wrapping portion 100, and then the height of the colloid filled and placed in the wrapping cavity can also be higher than the end face height of the wrapping portion 100. When the colloid solidifies and shrinks, the height of the solidified colloid is also higher than the end height of the wrapping portion 100, thereby avoiding the formation of a depression on the end face of the wrapping portion 100 and reducing the possibility of moisture accumulation in the wrapping portion 100. At the same time, a drainage channel 121 is provided on the end face of the wrapping part 100 close to the end of the pipe and cable, and the drainage channel 121 is connected to the side of the wrapping part 100 to improve the drainage capacity of the end. When moisture contacts the end of the wrapping part 100, the moisture will flow into the drainage channel 121 and quickly slide along the drainage channel 121 to the side of the wrapping part 100 until it is discharged. This avoids long-term water accumulation on the end face of the wrapping part 100, i.e., the end of the pipe and cable, ensures the insulation capacity of the cable itself after branching, and reduces the probability of sealing failure at the branching part of the pipe and cable, thereby reducing the probability of insulation failure, short circuit fire, equipment loss of control and other problems.

[0044] Furthermore, the extension part 200 is detachably connected to the wrapping part 100. One side of the extension part 200 is detachably connected to the end face of the opening side of the wrapping part 100, so that after the colloid is solidified, the extension part 200 can be disassembled. After disassembly, the top of the colloid is higher than the end face of the wrapping part, so that the colloid is prevented from forming a depression on the end of the wrapping part, and water is prevented from accumulating in the depression, thereby avoiding the risk of cable insulation failure caused by water accumulation.

[0045] Furthermore, the wrapping part 100 is arranged vertically, so that the wrapping cavity can be kept vertically arranged during the process of filling the colloid and curing the colloid, so that the outer surface of the cured colloid can be close to horizontal, thereby reducing the probability of water accumulation. At the same time, since the curing of the colloid requires a certain amount of time, the vertically arranged wrapping part 100 can prevent the colloid from being spilled.

[0046] In some specific embodiments of the present invention, referring to Figure 2, the extension part 200 is a cover 210. The two sides of the cover 210 in the axial direction are open, so that the cover 210 can be arranged around the axial direction of the wrapping cavity and cover the end surface of the wrapping part 100, so that the cover 210 and the wrapping cavity are coaxially arranged, and the height of the wrapping cavity can be extended through the inner wall of the cover 210, that is, when filling the colloid, the colloid can be continuously filled until the height of the colloid reaches and exceeds the end surface height of the cover 210. The height of the colloid can be significantly higher than the end surface height of the wrapping part 100, even if the colloid solidifies and shrinks, the height of the solidified colloid will be higher than the end surface height of the wrapping part 100. It avoids the situation that the colloid is lower than the end surface of the wrapping part 210, resulting in depressions on the colloid and accumulation of moisture. It can avoid the solidified colloid from contacting moisture for a long time, ensure the insulation capacity of the cable itself after the branching, and reduce the probability of sealing failure at the branching part of the pipe and cable, and reduce the probability of insulation failure, short circuit fire, equipment out of control and other problems.

[0047] In some specific embodiments of the present invention, referring to Figure 1 The wrapping part 100 includes: a cylinder 110 and a ring body 120. The inner wall of the cylinder 110 encloses a wrapping cavity, the inner diameter of the end of the cylinder 110 is larger than the outer diameter of the end of the tube and cable, the inner wall of the bottom of the cylinder 110 fits the outer wall of the tube and cable, and a glue filling space is formed between the inner wall of the end of the cylinder 110 and the outer wall of the tube and cable. At the same time, the bottom of the cylinder 110 is a sealing structure, so that it can be abutted with the outer wall of the tube and cable for sealing to prevent the colloid from leaking out, and the top of the cylinder 110 is an open structure, so that the colloid can be filled into the wrapping cavity from the open side of the cylinder 110. The ring body 120 is sleeved on the outer wall of the open side of the cylinder 110, so that the end face of the ring body 120 forms the end face of the wrapping part 100, and the drainage channel 121 is arranged on the end face of the ring body 120. The structure is simple and flexible, and it is easy to install and set.

[0048] Furthermore, a sealing rubber ring is provided at the bottom of the cylinder 110 to improve the sealing performance.

[0049] Furthermore, the combination of the cylinder 110 and the ring body 120 can be formed only by a simplified container that meets the shape and structure requirements, and the structure is simple and flexible, easy to install and set, and has low cost.

[0050] Furthermore, the overall combination of the cylinder 110 and the ring body 120 may also be a flange assembly, so that the combination of the cylinder 110 and the ring body 120 can also vertically suspend the pipe and cable, which is convenient for positioning and fixing.

[0051] It should be noted that the height of the end surface of one end of the opening side of the cylinder 110 is set higher than the end of the tube and cable, so that the colloid can cover the branching part of the end of the tube and cable.

[0052] In some specific embodiments of the present invention, referring to Figure 1 , the ring body 120 is provided with a drainage groove 1211. There are multiple drainage grooves 1211, which are arranged on the end face of the ring body 120, and the multiple drainage grooves 1211 are evenly arranged around the axial direction of the wrapping cavity. The two ends of the drainage groove 1211 extend along the radial direction of the ring body 120, one end of which extends to the inner wall side of the wrapping cavity, and the other end extends to the outer edge of the end face of the ring body 120. When water falls on the end face of the ring body 120, as the water accumulates, the accumulated water continuously flows into the drainage groove 1211 and can reach the outer edge of the ring body 120 along the drainage groove 1211 until it slides out of the ring body 120, thereby completing the drainage of water. It can prevent the end face of the ring body 120 and the cured colloid from contacting water for a long time, thereby preventing the situation in which the sealing of the pipe and cable fails after long-term immersion and water enters the inside of the pipe and cable along the gap between the colloid and the ring body 120. This avoids long-term water accumulation on the end face of the ring body 120, i.e., the end of the pipe and cable, thereby ensuring the insulation capacity of the cable itself after branching, and reducing the probability of sealing failure at the branching part of the pipe and cable, thereby reducing the probability of insulation failure, short circuit fire, equipment loss of control and other problems.

[0053] Furthermore, the boundary between the groove wall of the drainage groove 1211 and the end face of the ring body 120 is an arc-shaped structure, so that the water falling on the end face of the ring body 120 can flow into the drainage groove 1211, and the water is prevented from adhering to the end face of the ring body 120. It can prevent the end face of the ring body 120 and the cured colloid from being in contact with water for a long time, thereby preventing the seal failure of the pipe and cable after long-term immersion, and preventing water from entering the pipe and cable through the gap between the colloid and the ring body 120. It avoids the situation where the end face of the ring body 120, that is, the end of the pipe and cable, accumulates water for a long time, ensures the insulation capacity of the cable itself after the branching, and reduces the probability of sealing failure at the branching part of the pipe and cable, and reduces the probability of insulation failure, short circuit fire, equipment out of control and other problems.

[0054] In some specific embodiments of the present invention, referring to Figure 1 , the ring body 120 is also provided with an annular groove 1212. The annular groove 1212 is provided on the end face of the ring body 120, and the annular groove 1212 is arranged around the cavity, and a plurality of drainage grooves 1211 can be respectively connected with the annular groove 1212, and a plurality of drainage grooves 1211 are connected with the annular groove 1212 to form a drainage channel 121, thereby increasing the radiation area of ​​the drainage channel 121, so that it is convenient for moisture to be discharged through the drainage groove 1211. Moisture is prevented from contacting the end face of the ring body 120 for a long time, and the probability of problems such as sealing failure, insulation failure, short circuit fire, and equipment out of control is reduced.

[0055] Furthermore, there are multiple annular grooves 1212, which are coaxially arranged, and there is a gap between every two adjacent annular grooves 1212, so that the multiple annular grooves 1212 and the multiple drainage grooves 1211 can cover the entire end surface of the ring body 120, further increasing the radiation area of ​​the drainage channel 121, and facilitating the drainage of water through the drainage grooves 1211. This prevents water from contacting the end surface of the ring body 120 for a long time, and reduces the probability of problems such as sealing failure, insulation failure, short circuit fire, and equipment out of control.

[0056] In some specific embodiments of the present invention, referring to Figure 1 The end surface of the ring body 120 has an inclined structure with a high inner side and a low outer side. The height of the inner edge of the ring body 120 is higher than the height of the outer edge of the ring body 120, so that the water falling on the end surface of the ring body 120 can be prevented from flowing to the location of the package cavity, which is convenient for draining the water. At the same time, even if the water does not slide into the drainage groove 1211, under the action of the end surface of the inclined structure of the ring body 120, the water can be driven to gradually flow to the outer edge of the ring body 120. The bottom of the drainage groove 1211 also has an inclined structure with a high inner side and a low outer side. The height of the bottom of the drainage groove 1211 at one end close to the inner edge of the ring body 120 is higher than the height of the bottom of the drainage groove 1211 at one end close to the outer edge of the ring body 120, so that the water sliding into the drainage groove 1211 can be prevented from flowing along the drainage groove 1211 to the package cavity, and the water can be driven to flow along the drainage groove 1211 to the outer edge of the ring body 120 and slide out, which is convenient for draining the water. It can prevent the end face of the ring body 120 and the cured colloid from being in contact with water for a long time, thereby preventing the seal failure of the pipe and cable after long-term immersion, which causes water to enter the pipe and cable through the gap between the colloid and the ring body 120. It prevents the end face of the ring body 120, i.e., the end of the pipe and cable, from accumulating water for a long time, ensures the insulation capacity of the cable itself after branching, and reduces the probability of sealing failure at the branching part of the pipe and cable, and reduces the probability of problems such as insulation failure, short circuit fire, and equipment out of control.

[0057] Furthermore, the end surface of the ring body 120 may be an arc-shaped structure, and the bottom of the drainage groove 1211 may also be an arc-shaped structure, thereby further facilitating the flow of water.

[0058] In some specific embodiments of the present invention, referring to Figure 2 The cover body 210 and the ring body 120 are detachably connected, which can ensure that the cover body 210 is covered on the end surface of the ring body 120, so that the cover body 210 can be located above the cylinder body 110 in the setting position, and it is also convenient for the cover body 210 to be disassembled. After disassembly, the top of the colloid is higher than the end surface of the wrapping part, which prevents the colloid from forming a depression on the end of the wrapping part, avoids water accumulation in the depression, and thus avoids the risk of cable insulation failure caused by water accumulation.

[0059] It should be noted that the extension portion 200 can also exist in other forms other than the cover body 210. For example, the extension portion 200 can be formed by providing a baffle or extending the length of other components. The main purpose is to expand the glue pouring space.

[0060] In some specific embodiments of the present invention, referring to Figure 2 The circumferential dimension of the cover body 210 is matched with the circumferential dimension of the annular groove 1212, so that the bottom side of the cover body 210 can be embedded in the annular groove 1212, thereby completing the detachable connection between the cover body 210 and the ring body 120 and positioning the setting of the cover body 210. The structure is simple and flexible, and it is easy to install and disassemble.

[0061] In some specific embodiments of the present invention, referring to Figure 3 The cover body 210 is arranged to be retracted upward and inward on one side away from the ring body 120. The cover body 210 can limit the solidification shape of the colloid, so that the width of the lower end of the solidified colloid can be greater than the width of the upper end of the colloid, so that the upper end surface of the solidified colloid can form an inclined state with the inside higher and the outside lower, thereby avoiding the accumulation of moisture on the top of the colloid, and facilitating the moisture on the colloid to slide to the ring body 120, and then be discharged outward through the end surface of the ring body 120 or the drainage groove.

[0062] It should be noted that the side of the cover body 210 close to the ring body 120 is still cylindrical, so as to facilitate detachable connection with the ring body 120.

[0063] Reference Figure 4 The present invention also provides a method for sealing a pipe and cable branch line by pouring glue, which adopts the pipe and cable branch line pouring glue sealing structure described in any of the above specific embodiments, and comprises the following steps:

[0064] The extension part 200 is arranged on the end surface of the wrapping part 100, and the height of the wrapping cavity is extended by the extension part 200. The colloid is placed in the wrapping part 100, and the end surface of the placed colloid can be higher than the end surface of the wrapping part 100 through the extension part 200, leaving a shrinkage margin for the colloid after curing. The wrapping part 100 is arranged vertically, so that the wrapping part 100 is in a vertical state, so that the colloid in the wrapping cavity can be cured. After the colloid is cured, the extension part 200 is removed.

[0065] Specifically, the cover 210 and the wrapping cavity are coaxially arranged and cover the end surface of the ring body 120. The bottom side of the cover 210 is embedded in the annular groove 1212 of the ring body 120 to complete the fixation of the cover 210, and the height of the wrapping cavity is extended by the cover 210. The colloid is placed in the wrapping cavity, and under the restriction of the inner wall of the cover 210, the end surface of the placed colloid can be higher than the end surface of the ring body 120. The cylinder 110 is vertically arranged and fixed, so that the cylinder 110 drives the wrapping cavity to be in a vertical placement state together, so that the colloid in the wrapping cavity can be cured. At the same time, during the curing process of the colloid, under the restriction of the inner wall of the cover 210, the colloid forms a shape that is wide at the bottom and narrow at the top. After the colloid is cured, the cover 210 is removed.

[0066] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
