[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0026] Example

[0027] Figure 1-Figure 5 What is shown is a schematic diagram of the overall structure of a specific embodiment of the utility model. Figure 1-Figure 5 In the splicing type pipeline repair section, including splicing parts.

[0028] The splicing parts include a supporting half ring 1, a plug-in half ring 101, a plug-in arc 102, a plug-in groove 103, and a limiting tooth 104. The plug-in arc 102 is installed at the opposite ends of the plug-in half ring 101, and the plug-in groove 103 is opened at the opposite ends of the supporting half ring 1. The limiting teeth 104 are installed on both sides of the inner wall of the plug-in groove 103, and the outer side of the plug-in arc 102 is installed with a barb that is limited by the limiting tooth 104. The plug-in half ring 101 is plugged into the plug-in groove 103 through the plug-in arc 102, and the limiting tooth 104 is engaged with the barb.

[0029] A sealing piece is provided in the middle of the splicing piece.

[0030] The sealing member includes a middle sealing ring 2, an end point sealing ring 201, and a side sealing ring 202. The end point sealing ring 201 is located between the two middle sealing rings 2, and the side sealing ring 202 is located outside the two middle sealing rings 2. The end point sealing ring 201 is connected to the middle sealing ring 2 and the side sealing ring 202 at the same time. The end point sealing ring 201 is located at the connection between the supporting half ring 1 and the plug-in half ring 101, and the side sealing ring 202 is located at both ends of the supporting half ring 1 and the plug-in half ring 101.

[0031] A sealing auxiliary piece is provided on the outside of the splicing piece.

[0032] The sealing auxiliary piece is used to connect two adjacent splicing pieces and to seal both ends of the splicing pieces.

[0033] First, wrap the seal around the leaking area, place the middle seal ring 2 on both sides of the leaking area, then heat and melt the middle seal ring 2 and the side seal ring 202 at the end points to connect them, so that the end seal ring 201 is connected to the middle seal ring 2 and the side seal ring 202 as a whole, then place the support half ring 1 in contact with the seal, and then place the plug-in half ring 101 above the support half ring 1, plug the plug-in arc 102 into the plug-in groove 103, and then press the plug-in half ring 101 to plug the outside of the plug-in arc 102. The barb and the limiting tooth 104 are engaged so that the splicing arc 102 can only move toward the inside of the splicing groove 103. Then, the splicing half ring 101 is continuously pressed so that it is spliced and sealed with the supporting half ring 1 while its inner wall is tightly connected with the seal. Finally, the two ends of the splicing piece are sealed using a sealing auxiliary piece. Multiple splicing pieces are spliced together horizontally to increase the sealing area and improve the sealing effect of the device. Therefore, under the combined sealing of the seal and the sealing auxiliary piece, the stability and safety of the splicing seal of the splicing piece at the water flow point of the pipeline is guaranteed.

[0034] Figure 1 and Figure 3 Shown is a schematic diagram of the inner wall structure of a device as a specific embodiment of the present utility model. Figure 1 and Figure 3 In the figure, the splicing part also includes a middle arc groove 105 opened on the inner wall of the supporting half ring 1 and the plug-in half ring 101, a side arc groove 106 opened on the surface of both ends of the supporting half ring 1 and the plug-in half ring 101, and an end point arc groove 107 opened on the inner side of the two adjacent ends of the supporting half ring 1 and the plug-in half ring 101. The middle arc groove 105, the side arc groove 106, and the end point arc groove 107 are used for limiting the placement of the seal.

[0035] Under the mutual limitation of the sealing member by the middle arc-shaped groove 105, the side arc-shaped groove 106 and the end arc-shaped groove 107, the relative stability of the position of the splicing member and the sealing member during installation and use is guaranteed, and the sealing member can be squeezed and deformed under the continuous extrusion of the supporting half ring 1 and the plug-in half ring 101, thereby increasing the contact area between the sealing member and the splicing member, further ensuring the sealing effect. Therefore, when the sealing member is not heated and melted, the safety of the sealed connection at both ends of the sealing member can be guaranteed by the extrusion effect.

[0036] Figure 2 and Figure 3 What is shown is a schematic diagram of the connection state structure of a specific embodiment of the utility model. Figure 2 and Figure 3 There are at least two middle arc-shaped grooves 105 , and the middle sealing ring 2 is located inside the middle arc-shaped groove 105 ; there are at least two side arc-shaped grooves 106 , and the side sealing ring 202 is located inside the side arc-shaped groove 106 .

[0037] There are at least four endpoint arc grooves 107, and every two endpoint arc grooves 107 limit the endpoint sealing ring 201 at the same time, wherein the middle sealing ring 2 and the endpoint sealing ring 201 are both located inside the supporting half ring 1 and the plug-in half ring 101, and the side sealing ring 202 is located outside the supporting half ring 1 and the plug-in half ring 101.

[0038] By using the two middle arc-shaped grooves 105 in combination with the two middle sealing rings 2, the two sides of the leaking area are sealed. By using the two end arc-shaped grooves 107 in combination with the two end sealing rings 201, the connection between the supporting half ring 1 and the plug-in half ring 101 is sealed. At the same time, the two middle arc-shaped grooves 105 are sealed again to ensure that the leaking area is completely sealed. Then, by using the side arc-shaped grooves 106 at both ends and the side sealing rings 202 in combination, the sealing stability of both ends of the splicing piece is ensured, and multiple sealing effects are formed at the intersection of the middle sealing ring 2, the end sealing ring 201 and the side sealing ring 202, thereby further ensuring the stability of the device during sealing use.

[0039] Figure 5 Shown is a schematic diagram of the sealing structure of a specific embodiment of the present invention. Figure 5 In the figure, the sealing auxiliary parts include a sealing half ring 3 for sealing both ends of the device, a fastening support block 301 installed on the outer surface of the supporting half ring 1, the plug-in half ring 101 and the sealing half ring 3, and a fastening bolt 302 for fastening two adjacent fastening support blocks 301.

[0040] Under the fastening combination of the fastening bolt 302 and the fastening support block 301, the sealing half ring 3 is limited and fastened at both ends of the support half ring 1 and the plug-in half ring 101 to ensure the sealing stability of the sealing parts at both ends of the device. At the same time, the two adjacent splicing parts can be limited and fastened to ensure the stability of the connection state of multiple splicing parts.

[0041] Figure 5 Shown is a schematic structural diagram of a sealing auxiliary component as a specific embodiment of the present utility model. Figure 5 In the embodiment, each two sealing half rings 3 form a group and are located at one end of the device, and the side sealing rings 202 at both ends are located between the splicing piece and the sealing auxiliary piece.

[0042] By setting the sealing half ring 3 as a half arc, the installation and use of the sealing half ring 3 is facilitated, and the stable extrusion of the side sealing ring 202 is ensured by limiting the connection between the sealing half ring 3 and the connector, thereby further improving the sealing performance on both sides of the device.

[0043] Working principle: First, wrap the seal around the leaking area, place the middle sealing ring 2 on both sides of the leaking area, then heat and melt the end points of the middle sealing ring 2 and the side sealing ring 202 to connect them, so that the end sealing ring 201 is connected to the middle sealing ring 2 and the side sealing ring 202 as a whole, then place the supporting half ring 1 in contact with the seal, and then place the plug-in half ring 101 above the supporting half ring 1, so that the plug-in arc 102 is plugged into the plug-in groove 103, and then press the plug-in half ring 101, and the plug-in arc 102 can only move into the plug-in groove 103 under the engagement of the outer hook of the plug-in arc 102 and the limit tooth 104, and then continue to press the plug-in half ring 101. The half ring 101 is spliced and sealed with the supporting half ring 1, while the middle sealing ring 2, the end sealing ring 201, and the side sealing ring 202 are respectively limited by the middle arc groove 105, the side arc groove 106, and the end arc groove 107. Under the continuous extrusion of the supporting half ring 1 and the plug-in half ring 101, the seal can be squeezed and deformed to increase its contact area with the splicing part to ensure the sealing effect. Finally, rotate the fastening bolt 302 to drive the two adjacent fastening support blocks 301 to tighten and connect, and squeeze and seal the middle sealing ring 2 between the two splicing parts and the middle sealing ring 2 between the splicing part and the sealing auxiliary part to ensure the overall sealing of the device.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
