[0015] Furthermore, the connecting mechanism also includes multiple threaded sleeves that are threaded to the outside of multiple screws.

[0016] The beneficial effect of adopting the above-mentioned further solution is that when the flanges of the two submerged tubes are placed in the annular groove and locked by multiple screws, multiple threaded sleeves clamp and fix the two flanges to the mating parts.

[0017] Furthermore, the plurality of the threaded sleeves are movably fitted to the left side of the left flange, and the left ends of the plurality of the threaded rods penetrate the right flange, the mating parts and the right side of the left flange and extend to the left side of the left flange.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The first submerged pipe 1 and the second submerged pipe 3 are provided with the same docking part 5. A connecting mechanism 2 is provided on the outside of the docking part 5. A flange 4 is fixed on the opposite side of the first submerged pipe 1 and the second submerged pipe 3.

[0028] In this embodiment, annular grooves 6 are provided on opposite sides of the two flanges 4. Annular discs 7 that movably fit with the annular grooves 6 are fixed on the left and right sides of the two connecting parts 5. The two annular discs 7 are respectively inserted into the interior of the two annular grooves 6 to position the two flanges 4. Two inserts 8 located in the middle of the annular discs 7 are fixed on the left and right sides of the connecting parts 5. The two flanges 4 on opposite sides of the first sinking pipe 1 and the second sinking pipe 3 are aligned, and the inserts 8 fixed on the left and right sides of the connecting parts 5 are inserted into the interior of the first sinking pipe 1 and the second sinking pipe 3. When the connecting parts 5 are used to splice the sinking pipes, the two ends of the inserts 8 are respectively inserted into the pipe openings of the two sinking pipes, and the flanges 4 of the two sinking pipes are placed in the annular grooves 6. The two inserts 8 are respectively located inside the first sinking pipe 1 and the second sinking pipe 3. The shape of the connecting parts 5 is a hollow cylinder with missing left and right sides. The design of the hollow cylinder with missing left and right sides allows the first sinking pipe 1 and the second sinking pipe 3 to communicate.

[0029] Please see Figure 3-4 To improve its waterproof effect, the connecting mechanism 2 in this embodiment includes a waterproof sealing sleeve 201 that is movably attached to the outside of the docking part 5. Waterproof tape 202 is wrapped around the outside of the waterproof sealing sleeve 201. Multiple nuts 203 are movably attached to the right side of one flange 4. Each of the multiple nuts 203 has a screw 204 fixed to its left side.

[0030] In this embodiment, the connecting mechanism 2 also includes multiple threaded sleeves 205 threaded to the outside of multiple screws 204. When the flanges 4 of the two submerged pipes are placed in the annular groove 6 and locked by multiple screws 204, the multiple threaded sleeves 205 clamp and fix the two flanges 4 to the docking parts 5. The multiple threaded sleeves 205 are all movably attached to the left side of the left flange 4. The waterproof sealing sleeve 201 is put on the outside of the docking parts 5 in advance. After the multiple threaded sleeves 205 clamp and fix the two flanges 4 to the docking parts 5, the waterproof sealing sleeve 201 is moved to be located outside the docking parts 5 and to block the gap between the two flanges 4 and the docking parts 5. The left ends of the multiple screws 204 all pass through the right flange 4, the docking parts 5 and the right side of the left flange 4 and extend to the left side of the left flange 4. By wrapping multiple turns of waterproof tape 202 around the outside of the waterproof sealing sleeve 201, its waterproof effect is improved, and costs are saved, thereby improving the efficiency of installing and maintaining the underwater submerged pipe splicing components.

[0031] It should be noted that when the connecting piece 5 is used to splice the submerged pipes, the two ends of the insert 8 are respectively inserted into the pipe openings of the two submerged pipes, and the flanges 4 of the two submerged pipes are placed in the annular groove 6 and locked by multiple screws 204, so that multiple threaded sleeves 205 clamp and fix the two flanges 4 to the connecting piece 5. The waterproof sealing sleeve 201 is placed on the outside of the connecting piece 5 and blocks the gap between the two flanges 4 and the connecting piece 5. Then, the waterproof sealing sleeve 201 is wrapped with multiple turns of waterproof tape 202 to improve its waterproof effect.

[0032] It is understood that any part of this utility model not described in detail is known to those skilled in the art.

[0033] The working principle of the above embodiments is as follows:

[0034] (1) Align the two flanges 4 on the opposite side of the first sinking pipe 1 and the second sinking pipe 3, and insert the insertion tubes 8 fixed on the left and right sides of the docking piece 5 into the interior of the first sinking pipe 1 and the second sinking pipe 3, and make the two annular discs 7 respectively into the interior of the two annular grooves 6. When the docking piece 5 is used to splice the sinking pipes, the two ends of the insertion tubes 8 are respectively inserted into the pipe openings of the two sinking pipes, and the flanges 4 of the two sinking pipes are placed in the annular grooves 6, and locked by multiple screws 204, so that multiple screw sleeves 205 clamp and fix the two flanges 4 and the docking piece 5.

[0035] (2) Before fixing, the waterproof sealing sleeve 201 is put on the outside of the docking part 5 in advance. After the multiple threaded sleeves 205 clamp and fix the two flanges 4 and the docking part 5, the waterproof sealing sleeve 201 is moved to the outside of the docking part 5 and the gap between the two flanges 4 and the docking part 5 is blocked. Then, by wrapping multiple turns of waterproof tape 202 around the outside of the waterproof sealing sleeve 201, its waterproof effect is improved, and the cost is saved, thus improving the efficiency of installing and maintaining the underwater submerged pipe splicing component.
