Description

Technical Field

[0001] The present invention relates to the technical field of waterproof cables, and in particular to a cable with sealing and waterproofing functions. Background Art

[0002] A cable with a sealed and waterproof function refers to a cable that can be used normally in water. Its main function is to prevent moisture from entering the cable and ensure that the cable can operate stably for a long time underwater or in a humid environment. This type of cable usually uses a waterproof structure and material on the sheath.

[0003] However, affected by external factors, after the sheath of cables laid in water or in a humid environment for a long time is ruptured by the collision of external objects, moisture will pass through the contact between the sheath and the cable core, which will cause leakage of the cable outlet and make it impossible to use normally. After the cables with sealing and waterproof functions in the prior art are laid in water, their surfaces are damaged by impact and do not have the function of repair. In the actual power transmission operation, when the cables leak, it will not only cause large-scale power outages in the area and cause a large amount of economic losses, but also the replacement of the cables in the water is extremely complicated, which greatly increases the difficulty of maintenance.

[0051] The working principle and beneficial effects of the present invention are:

[0052] 1. The present invention starts the power motor after laying the cable body in the water, so that the output end of the power motor rotates back and forth alternately, and the rotation of the output end of the power motor drives the power worm to rotate, and the power worm drives the pressure screw to rotate when rotating, so that the pressure ball nut group on the pressure screw performs linear reciprocating motion, and the movement of the pressure ball nut group drives the pressure tube to move, and the movement of the pressure tube drives the hexagonal slider to move in the hexagonal pressure cylinder, when the hexagonal slider moves in the direction away from the three-way pipe two, the external gas will enter the hexagonal pressure cylinder through the air inlet pipe, and when the hexagonal slider moves in the direction close to the three-way pipe two, the gas in the hexagonal pressure cylinder will pass through the air outlet pipe Enter the three-way pipe, so that the gas is filled into the annular gas pipe and the liquid storage cylinder along the gas filling pipe and the punching pipe respectively. At this time, the liquid filling valve is closed, and the filled gas is filled into the corresponding flexible hollow protective pipe along the gas delivery elbow to pressurize the flexible hollow protective pipe. When the air pressure in the flexible hollow protective pipe reaches the preset value, the excess gas is discharged through the pressure relief valve, so that the gas flows in the flexible hollow pipe. In the process of power transmission of the cable body, the gas entering the hexagonal pressurizing cylinder can be cooled to achieve the cooling treatment of the cable body. In addition, the elasticity of the surface of the flexible hollow protective pipe can be increased by inflating and pressurizing the flexible hollow pipe, thereby improving the impact resistance of the surface of the flexible protective cover.

[0053] 2. In the present invention, during operation, when the surfaces of the flexible protective cover and the flexible hollow protective tube are damaged due to external impact, the gas in the flexible hollow protective tube will be discharged through the damaged holes or cracks, so that the air pressure in the damaged flexible hollow protective tube is reduced. When the air pressure in one of the flexible hollow protective tubes is reduced, the gas in the remaining intact flexible hollow protective tubes will flow into the damaged flexible hollow protective tube. The wind speed sensor corresponding to the flexible hollow protective tube is used to detect the airflow entering the flexible hollow protective tube, so that the position of the damaged flexible hollow protective tube can be quickly determined;

[0054] 3. In the present invention, when repairing the damaged flexible hollow protective tube, the position of the damaged flexible hollow protective tube is determined, the power motor is started, and the power worm is driven to rotate by the output end of the electric motor, and the power worm is driven to rotate by the power worm, and the rotation of the power worm is driven to rotate the push block feeding assembly, so that the feeding tube in the push block feeding assembly is connected with the damaged flexible hollow positioning tube, and then the feeding electric cylinder is started, and the feeding hole is moved from the feeding tube to the side of the feeding hole away from the flexible hollow protective tube through the movement of the output end of the feeding electric cylinder, and then the plugging block is placed into the feeding tube through the feeding hole, and then the infusion valve corresponding to the damaged flexible hollow protective tube is opened. Under the action of air pressure, the water-based polyurethane grouting liquid in the liquid storage cylinder enters the flexible hollow protective tube along the three-way pipe through the infusion bend pipe, and the feeding electric cylinder is started again, and the feeding block is driven to move by the output end of the feeding electric cylinder, and the plugging block is driven to move to the flexible hollow protective tube through the feeding block. On the side of the three-way pipe in the flexible hollow protective tube away from the feeding pipe, the plugging block squeezes the water-based polyurethane grouting liquid to make the water-based polyurethane grouting liquid move in the flexible hollow protective tube. After the plugging block is filled into the flexible hollow protective tube, the infusion valve is closed, the push block feeding assembly is reset, and the power motor is started again to pneumatically pressurize the flexible hollow protective tube. Under the action of air pressure, the gas will push the plugging block in the flexible hollow protective tube to move toward the damaged position. When the plugging block is about to move to the damaged position, the water-based polyurethane grouting liquid on the side of the plugging block close to the damaged position preferentially contacts the moisture at the damaged position. When the water-based polyurethane grouting liquid meets water, it reacts with water and solidifies into a colloid. The damaged position of the flexible hollow protective tube is sealed by the solidified colloid to prevent moisture from entering the flexible hollow protective tube. At the same time, the condensed colloid can also protect the cable body at the damaged position of the flexible hollow protective tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0082] When repairing the damaged flexible hollow protective tube 2, determine the position of the damaged flexible hollow protective tube 2, start the power motor 11, and drive the power worm 10 to rotate through the output end of the electric motor. The power worm 10 drives the power worm wheel 8 to rotate, and the rotation of the power worm wheel 8 drives the push block loading assembly to rotate, so that the loading tube 12 in the push block loading assembly is connected to the damaged flexible hollow positioning tube 6, and then start the loading electric cylinder 13, and the top material is pushed through the movement of the output end of the loading electric cylinder 13. The block 14 moves from the feeding tube 12 to the side of the feeding hole away from the flexible hollow protective tube 2, and then the plugging block is placed into the feeding tube 12 through the feeding hole, and then the infusion valve 37 corresponding to the damaged flexible hollow protective tube 2 is opened. Under the action of air pressure, the water-based polyurethane grouting liquid in the liquid storage cylinder 31 enters the flexible hollow protective tube 2 along the three-way pipe 15 through the infusion elbow 36, and the feeding electric cylinder 13 is started again. The output end of the feeding electric cylinder 13 drives the ejecting block 14 to move, and the ejecting block 1 4 drives the plugging block to move to the side of the three-way pipe 15 in the flexible hollow protective tube 2 away from the feeding pipe 12, and the plugging block squeezes the water-based polyurethane grouting liquid to make the water-based polyurethane grouting liquid move in the flexible hollow protective tube 2. After the plugging block is filled into the flexible hollow protective tube 2, the infusion valve 37 is closed, the push block feeding assembly is reset, and the power motor 11 is started again to pneumatically pressurize the flexible hollow protective tube 2. Under the action of the air pressure, the gas will push the plugging block in the flexible hollow protective tube 2 toward The damaged position is moved. When the plugging block is about to move to the damaged position, the water-based polyurethane grouting liquid on the side of the plugging block close to the damaged position will preferentially contact the moisture at the damaged position. When the water-based polyurethane grouting liquid meets water, it reacts with water and solidifies into a colloid. The solidified colloid is used to seal the damaged position of the flexible hollow protective tube 2 to prevent moisture from entering the flexible hollow protective tube 2. At the same time, the condensed colloid can also protect the cable body 1 at the damaged position of the flexible hollow protective tube 2.

[0083] It should be noted that after the damaged flexible hollow protective tube 2 is sealed, the flexible hollow protective tube 2 will be blocked. If multiple flexible hollow protective tubes 2 are damaged, the repair plan can only be a temporary plan, and the cable body 1 needs to be replaced at an appropriate time.

[0084] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
