Description

Technical Field

[0001] This invention belongs to the field of offshore wind power cable connection technology, and more specifically, it relates to a shielded detachable connector for 145kV offshore wind power cables. Background Technology

[0002] Offshore wind power cables are the core components for power transmission in offshore wind farms, serving as the "blood vessels" connecting wind turbines and the power grid. Connectors enable modular construction, allowing long-distance cables to be transported in sections and quickly spliced ​​on-site, reducing the difficulty of constructing ultra-long cables.

[0003] The following problems still exist with the currently used offshore wind power cable connectors: 1. The cable and connector are usually connected by compression, which makes it easy for the cable and connector to fall off, affecting the connection effect; 2. They usually lack auxiliary connection structures, which affects the connection effect; 3. When high temperatures occur at the cable connection point, they cannot automatically separate the connected cable. Summary of the Invention

[0004] This disclosure relates to a shielded detachable connector for 145kV offshore wind power cables, comprising a cable connector, a conductive connecting component, a reinforcing limiting component, and an insulating protective component. Four synchronous supports drive four metal limiting heads to move simultaneously, inserting the inner ends of the four metal limiting heads into the two cables, preventing the two metal connecting sleeves from detaching from the two cables. This provides an auxiliary connection effect for the two cables, improving their connectivity. When the connection point of the two cables experiences excessively high temperatures, four metal force-bearing rods automatically pass through eight semi-circular limiting blocks, achieving automatic separation of the cable connection. This solves the problems of easy detachment between the cable and connector, lack of auxiliary connecting structure, and inability to automatically separate the connected cables under high temperatures.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The four clamping threaded pins of this invention ensure that the two metal connecting sleeves are in a stable state after being connected to the two cables. When the operator rotates the four clamping threaded pins, the four synchronous brackets can drive the four metal limiting heads to move simultaneously, so that the inner ends of the four metal limiting heads are inserted into the two cables, preventing the two metal connecting sleeves from falling off the two cables and ensuring the connection effect between the two metal connecting sleeves and the two cables.

Furthermore, when the temperature at the connection point of the two cables becomes too high, the high temperature at the connection point is transmitted to eight semi-circular limit blocks through two metal connecting sleeves, two reinforcing metal frames, and four metal force-bearing rods. This causes the four metal force-bearing rods to automatically pass through the eight semi-circular limit blocks. When the four metal force-bearing rods pass through the eight semi-circular limit blocks, the connecting conductive block separates from the cable on the right, achieving automatic separation of the connection point of the two cables. At the same time, the two insulating protective covers limit the two metal connecting sleeves, preventing the two separated cables from moving out of the two insulating protective covers.

[0027] In this embodiment of the disclosure, such as Figure 8 As shown, the reinforcing limiting member 300 includes: a polygonal guide rod 301 and a reinforcing metal frame 302; the polygonal guide rod 301 is fixedly installed on the connecting conductive block 201; the reinforcing metal frame 302 is slidably installed on the outside of the polygonal guide rod 301, and the inner end of the reinforcing metal frame 302 is inserted into two circular grooves 1011; the reinforcing limiting member 300 also includes: a blocking ring 303 and a support spring b304; the blocking ring 303 is fixedly installed on the outer end of the polygonal guide rod 301; the support spring b304 is sleeved on the outside of the polygonal guide rod 301, and the support spring b304 is located between the connecting conductive block 201 and the reinforcing metal frame 302; Its specific function is as follows: Since the two polygonal guide rods 301 are fixedly installed on the connecting conductive block 201, and the two reinforcing metal frames 302 are slidably installed on the outside of the two polygonal guide rods 301, and the inner ends of the two reinforcing metal frames 302 are inserted into the four circular grooves 1011, they play a reinforcing role on the two metal connecting sleeves 101, so that the distance between the two metal connecting sleeves 101 will not change, and also realize the secondary auxiliary connection of the two cables 500, thereby improving the connection effect of the two cables 500.

[0028] In this embodiment of the disclosure, such as Figure 1 and Figure 10 As shown, the insulating protective component 400 includes: an insulating protective cover 401 and a semi-circular limiting block 402; there are two insulating protective covers 401, and the two insulating protective covers 401 are installed on the outside of the connection of the two cables 500, and the two insulating protective covers 401 are connected by screws; there are eight semi-circular limiting blocks 402, and the eight semi-circular limiting blocks 402 are fixedly installed on the two insulating protective covers 401; two metal force-bearing rods 3021 are respectively provided on the outer side of the two reinforcing metal frames 302, and the outer ends of the four metal force-bearing rods 3021 are in contact with the eight semi-circular limiting blocks 402; Its specific functions are as follows: Since the two insulating protective covers 401 are installed on the outside of the connection of the two cables 500 and the two insulating protective covers 401 are connected by screws, they play a positioning role for the four clamping threaded nails 104, preventing the four clamping threaded nails 104 from becoming loose; since the eight semi-circular limiting blocks 402 are fixedly installed on the two insulating protective covers 401, and two metal force-bearing rods 3021 are respectively provided on the outer side of the two reinforcing metal frames 302, and the outer ends of the four metal force-bearing rods 3021 are in contact with the eight semi-circular limiting blocks 402, they also play a positioning role for the two reinforcing metal frames 302, so that the two reinforcing metal frames 302 and the four circular grooves 1011 will not fall off. The eight semicircular limiting blocks 402 are made of materials that are prone to deformation or melting when the temperature rises, such as polystyrene and polyvinyl chloride. When the temperature at the connection point of the two cables 500 is too high, the high temperature at the connection point can be transmitted to the eight semicircular limiting blocks 402 through the two metal connecting sleeves 101, the two reinforcing metal frames 302, and the four metal force-bearing rods 3021, causing the four metal force-bearing rods 3021 to automatically pass through the eight semicircular limiting blocks 402. When the four metal force-bearing rods 3021 pass through the eight semicircular limiting blocks 402, the connecting conductive block 201 separates from the cable 500 on the right, realizing the automatic separation of the connection point of the two cables 500. At the same time, the two insulating protective covers 401 limit the two metal connecting sleeves 101, preventing the two separated cables 500 from moving out of the two insulating protective covers 401.

[0029] The specific usage and function of this embodiment are as follows: When using this invention, the operator first pre-cuts grooves on the two cables 500 to be connected, then installs two metal connecting sleeves 101 at the connection points of the two cables 500. Next, the operator tightens four clamping screws 104 with a wrench, ensuring that the inner ends of the four clamping screws 104 contact the two cables 500, thus maintaining a stable connection between the two metal connecting sleeves 101 and the two cables 500. When the operator rotates the four clamping screws 104, the four synchronous brackets 106 drive the four metal limiting heads 103 to move simultaneously, inserting the inner ends of the four metal limiting heads 103 into the two cables 500. This prevents the two metal connecting sleeves 101 from falling off the two cables 500, ensuring the effective connection between the two metal connecting sleeves 101 and the two cables 500. The conductive block 201 is inserted into the two cables 500, thus connecting them. The two movable metal heads 202, under the action of a supporting spring a203, remain in contact with the two cables 500, providing auxiliary connection and improving connectivity. The operator moves the two reinforcing metal frames 302 inwards, inserting their inner ends into the four circular grooves 1011, reinforcing the two metal connecting sleeves 101 and ensuring the spacing between them remains constant. This also achieves a secondary auxiliary connection between the two cables 500, further improving connectivity. The workers installed two insulating protective covers 401 on the outside of two sets of cable connectors 100, conductive connecting parts 200 and two sets of reinforcing limiting parts 300, so that the outer ends of the four metal force-bearing rods 3021 contact the eight semi-circular limiting blocks 402, which played a positioning role for the four clamping threaded nails 104, preventing the four clamping threaded nails 104 from becoming loose, and also played a positioning role for the two reinforcing metal frames 302, so that the two reinforcing metal frames 302 and the four circular grooves 1011 would not fall off. When the temperature at the connection point of the two cables 500 becomes too high, the high temperature at the connection point is transmitted to the eight semi-circular limiting blocks 402 through the two metal connecting sleeves 101, the two reinforcing metal frames 302, and the four metal force-bearing rods 3021. This causes the four metal force-bearing rods 3021 to automatically pass through the eight semi-circular limiting blocks 402. When the four metal force-bearing rods 3021 pass through the eight semi-circular limiting blocks 402, the connecting conductive block 201 separates from the cable 500 on the right, achieving automatic separation of the connection point of the two cables 500. At the same time, the two insulating protective covers 401 limit the two metal connecting sleeves 101, preventing the two separated cables 500 from moving out of the two insulating protective covers 401.
