Description

Technical Field

[0001] This utility model relates to the field of sacrificial anode connector technology, specifically a sacrificial anode quick-connect anode connector. Background Technology

[0002] In the field of marine engineering such as offshore wind power and offshore platforms, sacrificial anodes, as key components of cathodic protection for metal structures, need to be in a complex environment of high salinity, high humidity and strong water flow impact for a long time. The reliability of their connection with the protected body directly affects the anti-corrosion effect and equipment life.

[0003] Chinese Patent No. CN210314496U discloses a quick-installation structure for a sacrificial anode in offshore wind power. The structure includes an installation pipe embedded within the sacrificial anode and symmetrically exposed at both ends, and a connecting assembly based on a wind turbine pile. The installation pipe is an arc-shaped curved tube with a cavity extending inward along the same axis. The connecting assembly consists of a fixed mounting frame and a pair of grippers on the frame connected by a pivot and controlled to open and close. The outer diameter and curvature of each gripper are designed to match and fit within the cavity, and the center of the curved tube of the installation pipe coincides with the axial direction of the pivot. This quick-installation structure for a sacrificial anode in offshore wind power, through the rotation of the grippers and the engagement with the arc-shaped installation pipe, achieves rapid replacement of the sacrificial anode and enhances omnidirectional shear resistance. It also avoids repeated underwater welding and desoldering, improving underwater construction efficiency and safety, and optimizing the process.

[0004] The above-mentioned solutions have some drawbacks. The clamps and the arc-shaped assembly pipe rely on the outer diameter arc for interlocking, which makes them prone to loosening and falling off under the impact of omnidirectional water flow. The connection stability is insufficient. The protection is only provided by the skirt wing plate and the waterproof gasket. The interlocking parts are not fully sealed, and seawater seepage can easily cause corrosion. There are no vibration damping components, and vibration and impact can cause the clamps to fail. The fatigue resistance is poor. The assembly pipe has specific specifications, the clamp operation is complicated, and the adaptability and construction efficiency are low. Therefore, we need to propose a sacrificial anode quick-connect anode joint. Utility Model Content

[0022] 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.

[0023] Please see Figures 1-4This utility model provides a technical solution: a sacrificial anode quick-connect anode connector, including a male connector 1 and a female connector 2. The male connector 1 has a convex end structure, and the female connector 2 has a concave end structure. The convex end structure of the male connector 1 and the concave end structure of the female connector 2 are threadedly connected to achieve a detachable connection with the female connector 2 and conduct current. The internal space of the female connector 2 accommodates the convex end structure of the male connector 1. Its internal positioning and guiding component performs quick positioning and docking of the male connector 1. The male connector 1 is covered with a protective sleeve 3. The long groove 7 on the outer side of the protective sleeve 3 provides a sliding track for the guide block 4, forming protection for the exterior of the male connector 1 and guiding the movement of the guide block 4.

[0024] The female connector 2 is symmetrically equipped with positioning guide components for quick positioning and docking of the male connector 1. The positioning guide components include guide blocks 4 and first spring dampers 5. Square grooves 6 and guide grooves 16 are opened inside the sides of the female connector 2. The guide grooves 16 cooperate with the guide blocks 4 to guide the guide blocks 4 to slide in a predetermined direction to accurately position the male connector 1. The first spring dampers 5 are all installed laterally inside the square grooves 6. The square grooves 6 provide installation space for the first spring dampers 5 and restrict their movement direction. One end of the first spring damper 5 is connected to the inner wall of the square groove 6, and the other end of the first spring damper 5 is connected to one side of the guide block 4. The first spring damper 5 uses elastic force to keep the guide block 4 in a positioning state and assist the male connector 1 in docking. Under the action of the first spring damper 5, the guide block 4 moves laterally along the guide groove 16. During docking, it is inserted into the long groove 7 to guide the male connector 1 to quickly align with the female connector 2.

[0025] The outer surface of the protective sleeve 3 is provided with long grooves 7 that are adapted to the guide block 4. The length direction of the long grooves 7 is parallel to the central axis of the protective sleeve 3. The long grooves 7 provide a sliding path for the vertical part of the guide block 4, ensuring that the guide block 4 moves axially when it moves with the base plate 8. The protective sleeve 3 is covered with an annular base plate 8. The annular base plate 8 supports the protective sleeve 3 and transmits external force to drive the guide block 4 to slide. The inner side wall of the base plate 8 is fixedly connected with L-shaped moving rods 9 at the positions corresponding to the long grooves 7. When the moving rods 9 move with the base plate 8, they drive the guide block 4 to slide along the long grooves 7.

[0026] The movable rod 9 includes a horizontal part and a vertical part that are vertically connected. The horizontal part is fixed to the inner wall of the base plate 8. The end of the vertical part away from the base plate 8 extends to the direction of the long groove 7 and is fixedly connected to the bottom of the guide block 4. The vertical part can slide along the long groove 7.

[0027] A combined locking cover assembly for protecting and locking the male connector 1 and female connector 2 is symmetrically installed on the outside. The combined locking cover assembly includes a protective cover 10 and bolts 11. The protective cover 10 is fitted onto the connection between the male connector 1 and female connector 2. The protective cover 10 is composed of two semicircles symmetrically divided along the vertical central axis. A horizontal plate 12 is symmetrically arranged vertically at the joint of the protective cover 10. The protective cover 10 is locked by the horizontal plate 12 and bolts 11, forming protection at the connection and enhancing the connection stability through the clamping force. When the bolts 11 rotate, they drive the semicircles to move closer or further apart, thereby clamping or loosening the protective cover 10. The horizontal plate 12 is a rectangular plate structure with a through threaded hole in the center.

[0028] The horizontal plates 12 are connected by bolts 11 through threaded holes. The threaded hole in the center of the horizontal plate 12 allows the bolts 11 to pass through. The bolts 11 are symmetrically distributed to provide uniform locking force to fix the protective cover 10. Gaskets 13 are installed at the two semi-circular interfaces of the protective cover 10. The gaskets 13 fill the splicing gap and enhance the sealing and connection tightness of the protective cover 10. The top of the base plate 8 is provided with an annular groove 14. The bottom of the protective cover 10 is inserted into the annular groove 14. The annular groove 14 and the bottom of the protective cover 10 are inserted and engaged to circumferentially position the protective cover 10 and restrict its axial movement.

[0029] A second spring damper 15 is vertically and symmetrically installed between the top of the base plate 8 and the top of the protective cover 10. The axis of the second spring damper 15 is perpendicular to the upper surface of the base plate 8, and one end of it is fixed to the top of the base plate 8, while the other end is fixedly connected to the top of the protective cover 10. The axis of the second spring damper 15 is perpendicular to the upper surface of the base plate 8. It absorbs vibration energy through elastic deformation and reduces vibration stress at the connection.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
