[0028] Please refer to Figures 1 - 3As shown in the figure, a technical solution of a marine wind power connection sleeve provided by the utility model: a marine wind power connection sleeve includes a sleeve body 1 and a connection sleeve 2. An internal connection mechanism 3 for fixing the sleeve body 1 is installed inside the connection sleeve 2. The connection mechanism 3 includes a first sealing ring 31, a slider 32, and a limit block 33. The first sealing ring 31 is arranged inside the connection sleeve 2. The slider 32 is movably arranged inside the connection sleeve 2. The adjacent surfaces of the first sealing ring 31 and the slider 32 are mating inclined surfaces. The limit block 33 is arranged inside the connection sleeve 2 on one side of the slider 32. A second sealing ring 331 is arranged between the limit block 33 and the slider 32. First, the second sealing ring 331 is sleeved on the outer side of the sleeve body 1. Then, the first sealing ring 31 is placed inside the connection sleeve 2. Then, the sleeve body 1 is installed into the connection sleeve 2 and abuts against the inner ring of the first sealing ring 31, while driving the second sealing ring 331 into the connection sleeve 2. Finally, the limit block 33 is used to push the second sealing ring 331 to move towards the slider 32 side until the slider 32 drives the first sealing ring 31 to contract along the inclined surface towards the sleeve body 1 side. Through the connection mechanism 3, the limit block 33 drives the first sealing ring 31 to contract so that it tightly fits with the sleeve body 1, and at the same time drives the second sealing ring 331 to closely cooperate with the inner wall of the sleeve body 1 and the connection sleeve 2. The connection effect is good. The double-layer sealing ring structure can achieve better sealing performance and extend the service life of the cable.

[0029] The sleeve body 1 includes a waterproof layer 11, a wear-resistant layer 12, and an elastic layer 13. The elastic layer 13 is sleeved on the outer side of the cable. The wear-resistant layer 12 is sleeved on the outer side of the elastic layer 13. The waterproof layer 11 is sleeved on the outer side of the wear-resistant layer 12. The waterproof layer 11 is made of epoxy resin material. The wear-resistant layer 12 is made of polyurethane material. Elastic balls 131 are arranged inside the elastic layer 13. The elastic layer 13 wraps around the outer side of the cable. The elasticity of the elastic balls 131 is used to protect the cable and prevent the cable from breaking. The polyurethane material has the advantages of oil resistance and wear resistance. Being sleeved on the outer side of the elastic layer 13 can improve the wear resistance strength of the elastic layer 13. Epoxy resin has good waterproof performance. Wrapping around the outer side of the wear-resistant layer 12 can better isolate water.

[0030] A fixing block 21 is welded on the outer side of the connection sleeve 2. The limit block 33 is connected to the fixing block 21 through a bolt 22.

[0031] The slider 32 is slidably connected to a chute 23 opened inside the connection sleeve 2, which is convenient for the slider 32 to slide inside the connection sleeve 2.

[0032] Both the first sealing ring 31 and the second sealing ring 331 are made of silicone rubber, which has a good sealing effect, and is resistant to high and low temperatures and aging, extending the service life of the cable.

[0033] The outer side of the bolt 22 is threadedly connected with a double nut, and an axial force can be generated between the double nuts to increase the friction force and prevent the nut from loosening.

[0034] The working principle of the present utility model is as follows:

[0035] When a marine wind power connection sleeve of this embodiment is in use, first, the second sealing ring 331 is sleeved on the outer side of the sleeve body 1, then the first sealing ring 31 is placed inside the connecting sleeve 2, and then the sleeve body 1 is installed inside the connecting sleeve 2 and abuts against the inner ring of the first sealing ring 31. At the same time, the second sealing ring 331 is driven into the connecting sleeve 2. Finally, the limiting block 33 is used to push the second sealing ring 331 to move towards the slider 32 side until the slider 32 drives the first sealing ring 31 to contract along the inclined plane towards the sleeve body 1 side. Through the connecting mechanism 3, the limiting block 33 drives the first sealing ring 31 to contract so that it tightly fits with the sleeve body 1. At the same time, the second sealing ring 331 is driven to closely fit the inner wall of the sleeve body 1 and the connecting sleeve 2, and the connection effect is good. The double-layer sealing ring structure can achieve better sealing performance. The elastic layer 13 is wrapped on the outer side of the cable, and the elasticity of the elastic balls 131 is used to protect the cable and prevent the cable from breaking. The polyurethane material has the advantages of oil resistance and wear resistance, and sleeving it on the outer side of the elastic layer 13 can improve the wear resistance strength of the elastic layer 13. The epoxy resin has good waterproof performance, and wrapping it on the outer side of the wear-resistant layer 12 can better isolate water.
