In the process of dragging the submarine cable to the platform under water or when the submarine cable is required to be abandoned under water, waterproof sealing is needed to be carried out on the end head of the submarine cable so as to prevent seawater from entering the cable. At present, the traditional waterproof sealing of the cable end is carried out by a method of wrapping waterproof adhesive tapes on the cable end. But the current sealing mode of wrapping waterproof adhesive tape on the cable end is only suitable for shallow water working conditions. For the deepwater application environment, due to the fact that the pressure intensity at the deepwater is high, under the action of high water pressure, sea water still enters the cable only through a simple waterproof tape wrapping method, and the subsequent use of the cable is possibly affected, or the marine environment is polluted.

After the glue is applied, the glue application hole 1211 of the sealing member 120 is sealed.
When the cable 1000 with the sealing structure 100 sleeved at the end part is put into water, water pressure acts on the sealing sleeve 110, force is transferred to glue in the airtight space 130, the glue forms a reaction force to support the sealing sleeve 110, and the balance between the pressure in the airtight space 130 and the pressure of the external environment can be realized, so that the moisture in the external environment is prevented from being permeated into the sealing structure 100 to be contacted with the cable 1000 due to the pressure difference between the sealing structure 100 and the external environment, and the normal use of the cable 1000 is further influenced, or the cable 1000 is contacted with the moisture in the external environment to cause certain pollution to water resources. The sealing member 120 is used for filling glue into the closed space 130, so that not only can the air in the closed space 130 be discharged, but also the pressure of the closed space 130 can be balanced with the external pressure to realize sealing.

In addition, the sealing element 120 and the sealing sleeve 110 can also be connected by adopting threads 1212, an external thread 1212 is arranged at the outer side of the sealing element 120, an internal thread 1212 is arranged at one end of the sealing sleeve 110 connected with the sealing element 120, and the external thread 1212 of the sealing element 120 is matched with the internal thread 1212 of the sealing sleeve 110 to realize the connection of the sealing element 120 and the sealing sleeve 110.
By means of the screw 1212 connection, a tight connection of the sealing element 120 with the sealing sleeve 110 can also be achieved by increasing the friction between the sealing element 120 and the sealing sleeve 110. Of course, the seal body 121 and the seal sleeve 110 may also be fixedly connected, which is not limited herein.
In order to utilize the principle of internal and external pressure balance of the sealing structure 100 to seal the end of the cable 1000 in a waterproof manner, referring to fig. 4, the sealing member 120 in this embodiment includes a sealing member body 121 and a sealing cover 122, the sealing member body 121 is connected with the sealing sleeve 110, the sealing member body 121 is provided with a glue filling hole 1211, the glue filling hole 1211 is communicated with the airtight space 130, the sealing cover 122 is detachably connected with the sealing member body 121, and the sealing cover 122 is used for sealing the glue filling hole 1211.
At first, the sealing cover 122 is opened to expose the glue filling hole 1211, after the end of the cable 1000 is sleeved in the sealing sleeve 110, glue is filled into the sealing space 130 formed by the cable 1000, the sealing element body 121 and the sealing sleeve 110 together through the glue filling hole 1211 of the sealing element body 121, and after the sealing space 130 is filled with glue, the sealing cover 122 is covered to seal the glue filling hole 1211, so that the sealing structure 100 seals the end of the cable 1000.

In addition, one end of the sealing cover 122 may be fixedly connected to the sealing member body 121, and the other end of the sealing cover 122 may be detachably connected to the sealing member body 121, such as by a snap connection. The specific connection manner of the sealing cover 122 and the sealing member body 121 is not limited herein as long as the sealing cover 122 can seal or expose the glue-pouring hole 1211.
The glue filled glue in this embodiment is resin gel. The resin gel has high strength, strong toughness, good wear resistance and good chemical stability, and is not influenced by environments such as oxidation, humidity, acid and alkali. In addition, the resin gel has physical properties unique to different base materials, such as elasticity, hardness, tension, and the like. The cured resin gel has good insulativity, water absorption and compressive strength. Of course, other materials with strong toughness, high strength, water resistance and corrosion resistance can be adopted for the glue for glue filling, so long as the pressure of the closed space 130 and the pressure of the external environment can be balanced, the waterproof sealing effect can be achieved, and the material components adopted for concrete glue filling are not limited.
In order to improve the sealing effect of the sealing structure 100 on the cable 1000, please refer to fig. 4, and refer to fig. 1 to 3, the sealing sleeve 110 in this embodiment includes a cold-shrink tube 111 and a skeleton, the skeleton is disposed in the cold-shrink tube 111, the skeleton can be drawn relative to the cold-shrink tube 111, the cold-shrink tube 111 is used for sleeving the cable 1000, and an end of the cold-shrink tube 111 away from the cable 1000 is connected with the sealing member 120. The cold shrink tube 111 is supported by the internal skeleton prior to use of the sealing sleeve 110. When the cold shrink tube 111 is used, the cold shrink tube 111 is sleeved at the end part of the cable 1000, and when the cable 1000 is installed in the cold shrink tube 111, the framework in the cold shrink tube 111 is taken out, and the cold shrink tube 111 tightly wraps the cable 1000 according to the characteristics of the framework.
When the cable 1000 sleeved with the sealing structure 100 is put into a deepwater ocean environment, deepwater water pressure acts on the cold shrink tube 111, glue filled in the cold shrink tube 111 is further cooled by compressing the cold shrink tube 111, so that external pressure is transmitted to the glue in the cold shrink tube 111, the glue used for glue filling has good pressure resistance, supporting force can be provided for the cold shrink tube 111, and accordingly pressure balance between the pressure in the sealed space 130 formed by the cable 1000, the cold shrink tube 111 and the sealing piece 120 and the pressure of seawater in the external environment is achieved, and therefore external seawater is prevented from entering the sealing piece 120 and the cold shrink tube 111 due to pressure difference, the subsequent normal use of the cable 1000 is influenced, or the cable is contacted with the cable 1000, and the ocean environment is polluted.
The cold shrink tube 111 is made of an elastomer material, commonly used silicone rubber and ethylene propylene rubber, and is formed by injection vulcanization in a factory, and is expanded and lined with a plastic screw support to form various components of the cable 1000. Cold shrink tube 111 is typically used to insulate and protect wire and cable 1000 from physical injury, moisture, chemical contamination, and the like. The cold shrink tube 111 has the main function of insulation, and can completely wrap the electric wire, and the cold shrink tube 111 can protect the electric wire and the cable 1000 from being cut or damaged by external objects, thereby isolating the air and other substances between the outside and the electric wire.
In field installation, these pre-expansions are placed over the end or joint of the treated cable 1000 and the internally supported plastic helical strips, i.e., the backbone, are withdrawn to compress the cable 1000. The cold shrink tube 111 is used for wrapping the cable 1000 by elastic retractive force at normal temperature. The principle of operation of the cold shrink tube 111 is as follows: taking the silica gel cold shrink tube 111 as an example, raw rubber which is not vulcanized is easily torn, and can be gently torn by hands, but the vulcanized silica gel becomes very elastic like rubber. That is, after the vulcanization process, the silica gel cold-shrinkage tube 111 can deform under the action of external force, and at the same time, the molecules are still in an activated state at normal temperature, and after the external force is removed, i.e. the skeleton is removed, the resilience force between the molecules, i.e. the retraction of the molecules to a certain extent occurs due to the action of internal stress generated by the deformation.
To further ensure the reliability of the sealing of the cable 1000, please continue to refer to fig. 4, and in combination with fig. 1 to 3, the sealing structure 100 in this embodiment further includes at least one fastener 140, where the fastener 140 is sleeved outside the sealing sleeve 110. After the cold shrink tube 111 is drawn out of the carcass, the cold shrink tube 111 contracts and tightens the cable 1000, forming a certain initial preload. The fastener 140 is sleeved outside the cold shrink tube 111, so that the cable 1000 can be further hooped, the initial pretightening force between the cold shrink tube 111 and the cable 1000 is increased, and meanwhile, the cold shrink tube is matched and sealed with the sealing element 120 adopting the principle of internal and external pressure balance, so that the reliability of the end sealing of the cable 1000 is guaranteed.
To facilitate assembly of the fastener 140 with the cold shrink tube 111 and increase the preload of the cold shrink tube 111 and the cable 1000, the fastener 140 in this embodiment is a ferrule 141. The throat hoop 141 has the advantages of easy installation and disassembly, the throat hoop 141 can be contracted in a 360-degree dead angle-free equal proportion, and the tightening force can be maintained. While the laryngeal cuff 141 has torsional and compressive properties. In addition, other tightening methods may be used to strengthen the pre-tightening force between the cold shrink tube 111 and the cable 1000, which is not limited herein. The number of the ferrules 141 in this embodiment is four, one is disposed at the end of the cold shrinkable tube 111 where the cable 1000 is sleeved, one is disposed at the end of the sealing member 120, and the other two are disposed at the middle position of the cold shrinkable tube 111 at intervals. Of course, the number of the ferrules 141 may be one, two or more, and is not limited herein, according to specific sealing requirements.
The working principle of the sealing structure 100 according to the present embodiment is as follows:
first, a layer of waterproof tape and PVC tape (polyvinyl chloride tape) is wrapped around the cable 1000, and then the cold shrink tube 111 is sleeved outside the cable 1000 by a suitable length from the end of the cable 1000. The cold shrink tube 111 is then withdrawn adjacent the backbone support in one end of the cable 1000, causing the cold shrink tube 111 to shrink and pinch on the cable 1000. The outside of the tightly-tied cold shrink tube 111 is further tied by the throat hoop 141.
