Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a flexible connection device for inter-module cable trays in modular devices. Background Technology

[0002] Offshore utility tunnels refer to integrated pipeline systems laid in the marine environment for the centralized deployment of submarine cables (power / communication), water / gas pipelines, and other facilities. These tunnels are composed of interconnected pipeline modules. When laying submarine cables within these tunnels, cable trays are needed to support the cables. Due to the complexity of the seabed environment, offshore utility tunnels are prone to shifting and settling. Flexible connection mechanisms are required between the cable trays to prevent rigid tension damage. However, existing flexible connections rely on bolts, requiring a large number of bolts to be tightened during installation, resulting in low installation efficiency. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0019] like Figures 1 to 4 As shown, this embodiment provides a flexible corrugated support pipe 1 whose cross-section is adapted to the cross-sectional shape of the cable tray. The two ends of the flexible corrugated support pipe 1 are respectively equipped with first docking parts 2. The end of the cable tray is fixed with a second docking part 3 made of iron that docks with the first docking parts 2. The first docking parts 2 and the second docking parts 3 are docked and fixed by a magnetic positioning mechanism. The magnetic positioning mechanism includes a plurality of strip permanent magnets 4 arranged circumferentially on the back side of the first docking parts 2 for magnetizing the second docking parts 3.

[0020] The first docking member 2 has a plurality of parallel positioning pins 5 on the docking surface that docks with the second docking member 3, and the second docking member 3 has a hole 6 that corresponds one-to-one with the positioning pins 5 and allows the positioning pins 5 to pass through.

[0021] The first and second docking parts 2 are provided with mechanical locking mechanisms 7 for connecting and locking the two sides of the first and second docking parts 2 and 3. This invention uses a flexible corrugated support pipe 1 with a cross-sectional shape adapted to the cable tray as the main body, and first docking parts 2 are respectively installed at both ends of the flexible corrugated support pipe 1. Simultaneously, an iron second docking part 3 is fixed at the end of the cable tray. Multiple strip-shaped permanent magnets 4 are provided on the back side of the first docking parts 2, thus magnetically attracting the second docking parts 3, allowing the first and second docking parts 2 and 3 to dock. Then, the mechanical locking mechanism 7, with pins 10 as the positioning body, connects and locks the two sides of the first and second docking parts 2 and 3. This facilitates assembly and eliminates the need for numerous bolts, thereby improving assembly efficiency.

[0022] The mechanical locking mechanism 7 includes a positioning plate 8 disposed on the back side of the first docking member 2 and perpendicular to the first docking member 2. The positioning plate 8 has a pin hole 9, and the second docking member 3 has a pin 10 corresponding to the position of the pin hole 9, which is mounted on the positioning bracket 18. The pin 10 has a baffle 11 on the side near the pin hole 9, and a tightening spring 12 is provided between the baffle 11 and the positioning bracket 18, which is sleeved on the outside of the pin 10. Then, the mechanical locking mechanism 7, with the pin 10 as the positioning body, is used to connect and lock the two sides of the first docking member 2 and the second docking member 3. This facilitates assembly and eliminates the need to screw in a large number of bolts, thereby improving assembly efficiency. This avoids separation during subsequent use due to insufficient magnetic attraction. The pin is used to position the first docking member and the second docking member to prevent separation, and it also has the advantage of convenient assembly. In its natural state, under the action of the tightening spring, the pin is always inserted into the pin hole.

[0023] The outer end of the pin 10 is provided with a handle 13 for easy operation.

[0024] The positioning bracket 18 is provided with a positioning mechanism for positioning the pin 10 after it is pulled out of the pin hole 9. The positioning mechanism includes a through hole 14 on the pin 10. After the pin 10 is pulled out, the through hole 14 is located at the upper part of the positioning bracket 18, and a horizontally arranged positioning rod 15 is inserted into the through hole 14. An anti-detachment rope 16 is connected between the positioning rod 15 and the positioning bracket 18. In this way, before the first docking piece and the second docking piece are docked, the pin 10 is pulled back, and then the positioning rod is used to pull out the pin 10 for positioning. This makes it convenient for the pin to extend and affect the docking of the first docking piece and the second docking piece. After the first docking piece and the second docking piece are docked, the positioning rod 15 can be pulled out. Under the action of the tightening spring, the pin is inserted into the pin hole to achieve the locking operation.

[0025] The positioning bracket 18 is provided with a limiting tube 17 for the pin 10 to pass through, and the tightening spring 12 is sleeved on the outside of the limiting tube 17, thus ensuring that the pin moves in a straight line.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
