Technical Field

[0001] The invention belongs to the technical field of power pipeline installation, and relates to a power pipeline installation and fixing device. Background Art

[0002] Power pipelines are infrastructure components used to protect and guide power cable transmission, providing physical protection for cables to prevent them from being directly damaged by external factors, and can effectively isolate cables from the external environment, reducing the impact of external electromagnetic interference on cable transmission signals. Power pipelines are essential and important facilities in many marine industries such as submarine cables, optical cables, wind power projects, oil and gas development, and marine aquaculture, and are of great significance to the development and growth of marine industries.

[0003] Due to the limited length of the power pipeline, a single pipeline cannot meet the long-distance laying requirements, which requires connecting multiple sections of pipelines to form a complete power transmission channel. The existing Chinese patent with authorization announcement number CN215419421U discloses a fixing device for power cable protection pipes, which can squeeze and fix the pipeline, but cannot effectively deal with the misalignment or looseness that is easy to occur during the installation of the pipeline. In addition, due to the large size of the power pipeline, when two power pipelines are docked and fixed, especially in an offshore environment due to the influence of wind and waves, there are problems such as inconvenient operation and low efficiency.

[0004] In order to solve the above problems, the present invention proposes a power pipeline installation and fixing device. Summary of the invention

DETAILED DESCRIPTION

[0024] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0025] like Figure 1-Figure 8 As shown, the technical solution adopted by the present invention is as follows: a power pipeline installation and fixing device includes a first fixing ring 1, a second fixing ring 2, a retaining ring 17 and a clamping plate 14. The first fixing ring 1 and the second fixing ring 2 are respectively fixed on two power pipelines to be fixed. Specifically, the first fixing ring 1 and the second fixing ring 2 are sleeved on the corresponding power pipelines, and a plurality of screws 3 are used to achieve fixed connection with the corresponding power pipelines.

[0026] The first fixing ring 1 is provided with a winding mechanism, on which a traction rope 10 is wound. The free end of the traction rope 10 slides through the first fixing ring 1 and the second fixing ring 2 in sequence and is fixedly connected to a stopper 11.

[0027] The winding mechanism includes a first worm 8, a first worm wheel 6 and a roller 5. A first drive box 4 is fixedly mounted on the first fixed ring 1, a first drive shaft 7 is rotated in the first drive box 4, one end of the first drive shaft 7 extends to the outside of the first drive box 4 and is fixedly connected to a rotating rod 9, and the first drive shaft 7 is rotated by rotating the rotating rod 9. The roller 5 is rotatably mounted in the first drive box 4, and the roller 5 and the first drive shaft 7 are vertically arranged. The first worm 8 is coaxially fixedly connected to the first drive shaft 7, the first worm wheel 6 is coaxially fixedly connected to the roller 5, and the first worm 8 and the first worm wheel 6 are meshed. The traction rope 10 is wound around the roller 5, and the free end of the traction rope 10 slides through the first drive box 4, the first fixed ring 1, and the second fixed ring 2 in sequence. By gradually winding the traction rope 10 around the roller 5, the first fixed ring 1 and the second fixed ring 2 are gradually approached, and the two power pipelines are contacted.

[0028] The first fixing ring 1 and the second fixing ring 2 are coaxially fixedly connected with a retaining ring 17. A notch is provided on the retaining ring 17. Guide surfaces 19 are provided at both ends of the retaining ring 17. A slot 18 is provided on the opposite sides of the two retaining rings 17. A rounded corner is provided on the side of the guide surface 19 close to the corresponding slot 18. When the two power pipelines are contacted by tightening the traction rope 10, the notches of the two retaining rings 17 are opposite to each other.

[0029] There are two card plates 14, and both card plates 14 are rotatably mounted on the first fixed ring 1. Specifically, a slide groove 12 is coaxially provided on the circumferential surface of the first fixed ring 1, and a slider 13 is fixedly connected to the card plate 14, and the slider 13 is limitedly slidably set in the slide groove 12. Both ends of the card plate 14 are fixedly connected with a protrusion 15. The protrusion 15 cooperates with the card groove 18. The two protrusions 15 on the same card plate 14 are respectively inserted into the two card grooves 18, so that the first fixed ring 1 and the second fixed ring 2 are fixedly connected, and the fixed connection of the two power pipelines is realized. In order to make the protrusion 15 smoothly inserted into the card groove 18, a curved surface is provided on one side of the protrusion 15. The side of the card plate 14 close to the first fixed ring 1 is curved, so that the card plate 14 can slide smoothly along the guide surface 19. When the card plate 14 slides along the guide surface 19 and the retaining ring 17, the two retaining rings 17 can be pushed to be flush. After the two power pipelines are in contact, the clamping plate 14 passes through the gaps of the two retaining rings 17 .

[0030] The first fixed ring 1 is provided with a driving assembly for driving the card plate 14 to rotate. The driving assembly includes an end face gear ring 16 and a gear 22. The first fixed ring 1 is fixedly provided with a second driving box 20, and a second driving shaft 24 is rotatably provided in the second driving box 20. One end of the second driving shaft 24 extends outside the second driving box 20 and is fixedly connected with a rotating handle 25. The second driving shaft 24 in the second driving box 20 is coaxially fixedly connected with a second worm 23. A second worm gear 21 is rotatably provided in the second driving box 20, and the second worm gear 21 meshes with the second worm 23. The second worm gear 21 is coaxially fixedly connected with the gear 22. Each card plate 14 is fixedly connected with an end face gear ring 16, and the end face gear ring 16 is coaxially provided with the first fixed ring 1. Both end face gear rings 16 slide through the second driving box 20, and the two end face gear rings 16 are arranged on both sides of the gear 22 and mesh with the gear 22. By turning the handle 25, the second worm 23 rotates, the second worm wheel 21 rotates, the gear 22 drives the end face gear ring 16 to rotate, the two clamping plates 14 move away from each other, the clamping plates 14 move to the retaining ring 17 through the guide surface 19, and the protrusion 15 is clamped into the clamping groove 18, so that the first fixing ring 1 and the second fixing ring 2 are fixedly connected.

[0031] Working principle: Initially, the clamping plate 14 is located at the notch of the retaining ring 17 on the first fixing ring 1.

[0032] When in use, the first fixing ring 1 is fixed to one of the power pipelines to be connected through the screw rod 3, and the first fixing ring 1 is flush with the corresponding power pipeline opening. Then the rotating rod 9 is rotated, the first driving shaft 7 is rotated, the roller 5 is rotated, and the traction rope 10 is released, so that the second fixing ring 2 can be installed on another power pipeline. The second fixing ring 2 is installed to the end of another power pipeline through the screw rod 3 and the second fixing ring 2 is flush with the power pipeline opening.

[0033] Then, the rotating rod 9 is rotated, the first driving shaft 7 is rotated, and the winding roller 5 is rotated, so that the traction rope 10 is gradually wound around the winding roller 5, and the traction rope 10 is reeled in, so that the second fixing ring 2 is close to the first fixing ring 1, until the first fixing ring 1 and the second fixing ring 2 are in contact. When the second fixing ring 2 is close to the first fixing ring 1, the clamping plate 14 passes through the gap of the retaining ring 17 on the second fixing ring 2.

[0034] Afterwards, the rotating handle 25 is turned, the second drive shaft 24 rotates, and under the transmission of the second worm 23 and the second worm wheel 21, the gear 22 rotates, the end face tooth ring 16 rotates and the rotation directions of the two end face tooth rings 16 are opposite, the two clamping plates 14 move away from each other, and the slider 13 slides along the slide groove 12. The clamping plate 14 slides onto the retaining ring 17 along the guide surface 19, and the protrusion 15 is inserted into the corresponding clamping groove 18, so that the two power pipelines are docked and fixed. The clamping plate 14 fits the two power pipelines tightly together. During the sliding process of the clamping plate 14 along the guide surface 19 onto the retaining ring 17, the first fixing ring 1 and the second fixing ring 2 can be pushed to a completely flush state to avoid the first fixing ring 1 and the second fixing ring 2 from being misaligned or not fitting, thereby improving the connection quality of the power pipeline. When the two clamping plates 14 are symmetrically distributed on both sides of the power pipeline, the rotating handle 25 can be stopped. The installation and fixing device of the present invention can dock and fix two power pipelines by rotating the rotating rod 9 and the rotating handle 25, which is simple and convenient to operate and is conducive to improving installation efficiency and installation quality.
