Description

Technical Field

[0001] This application relates to the field of pipe connection technology, and specifically to a pipe connection structure. Background Technology

[0002] A pipeline is a device made up of pipes, pipe fittings, valves, etc., used to transport gases, liquids, or fluids containing solid particles. Typically, fluids are pressurized by blowers, compressors, pumps, boilers, etc., and then flow from the high-pressure area to the low-pressure area in the pipeline. They can also be transported using the fluid's own pressure or gravity. Pipelines have a wide range of applications, mainly used for water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations.

[0003] In addition to the need for connection mechanisms during connection, when a pipeline breaks under external force during use, the damaged part needs to be cut off and the disconnected pipeline needs to be reconnected through a connecting pipe. However, since some pipelines are buried deep underground and cannot be moved during maintenance, the connecting pipe is difficult to pass through the gap between the pipeline breaks and fit over the two broken ends of the pipeline, making it inconvenient to use. In order to reasonably improve this problem, this application proposes a pipeline connection structure. Utility Model Content

[0004] The purpose of this application is to solve the technical problem that some pipelines are buried deep underground and cannot be moved during maintenance, and the connecting pipe is difficult to pass through the disconnection gap of the pipeline and fit on the two disconnected ends of the pipeline, making it inconvenient to use. This application provides a pipeline connection structure.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution:

[0006] A pipe connection structure, comprising:

[0007] Two cannulas are inserted into the two disconnected ends of the pipe, respectively, with their opposite ends pressed tightly against the inner wall of the pipe.

[0008] The installation tube consists of two detachably connected half-pipes, and both ends of the installation tube are fixed to the two disconnected ends of the pipe by fasteners.

[0009] The drive unit is located inside the mounting tube, and can drive the opposite ends of the two insertion tubes to come into close contact.

[0010] Furthermore, the fastener includes a flexible sleeve fitted onto the disconnected end of the pipe, and strip-shaped protrusions are linearly distributed on the inner side of the half-pipe, which abut and overlap with the outer side of the flexible sleeve.

[0011] Furthermore, each of the two sides of one of the semi-tubes has a receiving groove, and a sealing strip is installed in each of the receiving grooves. The two sealing strips respectively abut and overlap with the two sides of the other semi-tube.

[0012] Furthermore, the drive unit includes an annular plate constructed at the opposite end of the insertion tube, and a slot is constructed inside the half-tube.

[0013] Furthermore, magnets are distributed in a ring on opposite sides of the two ring plates, and the magnets on both sides are magnetically attracted to each other.

[0014] Furthermore, both of the two annular plates have inclined surfaces on their opposite sides, and the distance between the two inclined surfaces gradually decreases from the axis of the annular plate toward its outer side. The two inclined surfaces respectively abut and overlap with the inner walls on both sides of the slot.

[0015] Furthermore, annular grooves are constructed on opposite sides of the two annular plates, an annular pad is installed in one of the annular grooves, and the annular pad abuts and overlaps with the inner wall of the other annular groove.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figures 1-4 As shown, one embodiment of this application proposes a pipe connection structure, including:

[0026] Two insert tubes 1 are inserted into the two disconnected ends 2 of the pipe respectively, with their opposite ends close to the inner wall of the pipe. The length of a single insert tube 1 is less than the distance between the two disconnected ends 2 of the pipe. After inserting the insert tube 1 into the disconnected end 2 of the pipe, it can continue to slide. This design makes it easy to insert the two insert tubes 1 into the disconnected end 2 of the pipe, and after insertion, the positions of the two insert tubes 1 can be adjusted to make them close to each other.

[0027] The installation tube 3 consists of two detachably connected half-pipe bodies 301. The two half-pipe bodies 301 are connected to each other by bolt assembly 4. The length of the half-pipe body 301 is greater than the distance between the two disconnected ends 2 of the pipe. The two ends of the installation tube 3 are fixed to the two disconnected ends 2 of the pipe by fasteners 5. After inserting the two insertion tubes 1 into the two disconnected ends 2 of the pipe, the two half-pipe bodies 301 can be spliced ​​together and fixed to the pipe by fasteners 5, thereby connecting the two disconnected ends 2 of the pipe to each other.

[0028] The drive unit 6 is located inside the mounting tube 3. After the mounting tube 3 is fixed on the pipe, the drive unit 6 can drive the two insertion tubes 1 to come into close contact with each other. That is, the drive unit 6 drives the two insertion tubes 1 to slide relative to each other, thereby fixing the two insertion tubes 1. At the same time, the two disconnected ends 2 of the pipe are connected through the two insertion tubes 1.

[0029] When encountering a situation where the maintenance pipeline cannot be moved, two insertion tubes 1 can be inserted into the two disconnected ends 2 of the pipeline respectively. Then, the two half-pipes 301 are spliced ​​to the outside of the pipeline by bolt assembly 4, and fixed to the pipeline by fastener 5. Finally, the two insertion tubes 1 are forced to slide and abut against each other by drive unit 6, thereby connecting the two disconnected ends 2 of the pipeline. This application is composed of multiple structures spliced ​​and fixed. Compared with the prior art, it is convenient to connect the two disconnected ends 2 of the pipeline by the disconnection distance of the pipeline, which is convenient for use and has practicality.

[0030] like Figures 1-3As shown, in some embodiments, the fastener 5 includes a flexible sleeve 501 fitted onto the disconnected end 2 of the pipe. The flexible sleeve 501 is a silicone sleeve. After cleaning and polishing the outside of the disconnected end 2 of the pipe, the flexible sleeve 501 can be fitted onto its outside. The inner side of the half-pipe 301 is linearly distributed with strip-shaped protrusions 502. The strip-shaped protrusions 502 are arc-shaped. After the two half-pipes 301 are connected, the corresponding strip-shaped protrusions 502 on their inner walls can form a ring and abut against and overlap with the outside of the flexible sleeve 501. The two strip-shaped protrusions 502 forming a ring can squeeze each other. The deformed flexible sleeve 501 can form a large abutment force on the outside of the pipe, thereby fixing the two half-pipes 301 to the outside of the pipe.

[0031] like Figure 2 and Figure 3 As shown, in some embodiments, a receiving groove 7 is constructed on both sides of one of the half-tubes 301 along the edge. The receiving groove 7 extends along the length of the half-tube 301. A sealing strip 8 is installed in each of the receiving grooves 7. The sealing strip 8 is a silicone strip. The two sealing strips 8 respectively abut and overlap with the edges of the other half-tube 301. With the help of the flexible sleeve 501, the connection sealing of the two half-tubes 301 can be effectively improved. With this design, no leakage will occur when the medium seeps out through the two insertion tubes 1.

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the drive unit 6 includes an annular plate 601 constructed at the opposite end of the insertion tube 1, and a slot 602 is constructed on the inner side of the half tube 301. The slot 602 is used to accommodate two annular plates 601. When the two half tubes 301 are connected, the slot 602 can be aligned with the two annular plates 601. The slot 602 restricts the two annular plates 601 from moving back to back so that they can come into close contact.

[0033] like Figure 4 As shown, in some embodiments, magnets 9 are distributed in a ring on opposite sides of the two annular plates 601, and the magnets 9 on both sides are magnetically attracted to each other. The magnets 9 are embedded in the annular plates 601. During installation, the two annular plates 601 are attracted to each other through the magnets 9. At this time, the two are magnetically connected and not easy to separate, which makes it easy to align the slot 602 with it.

[0034] like Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the two annular plates 601 are each constructed with inclined surfaces 10 on opposite sides, and the distance between the two inclined surfaces 10 gradually decreases from the axis of the annular plate 601 toward its outer side. The longitudinal section of the slot 602 is frustoconical, and its slot diameter is relatively large. The two inclined surfaces 10 respectively abut and overlap with the inner walls on both sides of the slot 602. This design makes it easy to align and insert the two annular plates 601 into the slot 602, and under the abutment of the inner wall of the slot 602, the two annular plates 601 fit tightly together, and gaps are not easy to occur.

[0035] like Figure 4 As shown, in some embodiments, annular grooves 11 are constructed on opposite sides of the two annular plates 601. An annular pad 12 is installed in one of the annular grooves 11. The annular pad 12 is a rubber pad, and the annular pad 12 abuts and overlaps with the inner wall of the other annular groove 11. This design can improve the sealing of the two insertion tubes 1 after installation.

[0036] like Figure 4 As shown, in some embodiments, the inner edges of the opposite ends of the two insertion tubes 1 are each constructed with an arc surface 13. The distance between the arc surface 13 and the outer side of the insertion tube 1 gradually decreases from the annular plate 601 toward the insertion tube 1. This design allows the medium flowing in the pipe to enter the insertion tube 1 along the arc surface 13, so that the medium is less likely to impact the end of the insertion tube 1.

[0037] like Figure 2 and Figure 4 As shown, in some embodiments, sealing rings 14 are installed on opposite ends of the insertion tube 1. The sealing rings 14 are rubber rings, embedded on the outside of the insertion tube 1, and the sealing rings 14 abut against and overlap with the inner wall of the pipe, thereby improving the sealing performance of the insertion tube 1 after it is connected to the pipe.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
