Description

Technical Field

[0001] The present invention relates to the technical field of corrosion-resistant cables, and in particular to a corrosion-resistant cable. Background Art

[0002] Corrosion-resistant cable is a special cable that can maintain stable and safe transmission of electrical signals or power in harsh environments. This cable is usually used in industrial and mining enterprises such as petroleum, chemical, power generation, and metallurgy.

[0003] The difference between corrosion-resistant cables and ordinary cables is not only in the obvious difference in structural settings, but also the materials need to be selected with acid and alkali resistance, so there is a higher cost in the production process.

[0004] The corrosion-resistant cables in the prior art, although they have strong corrosion resistance, can only extend the service life of the cables themselves during actual use. If used in harsh environments for a long time, the surface of the corrosion-resistant cables will still be corroded and the cables have to be replaced. Replacing the cable body will not only cause downtime, but also bring great costs. For this reason, we propose a corrosion-resistant cable. Summary of the invention

[0005] The present invention provides a corrosion-resistant cable, which is used to solve the problem in the background art that the corrosion-resistant cables in the prior art need to be completely replaced after being severely corroded.

Each of the hollow support detection plates is provided with a cable threading hole, and the cable threading holes correspond to the sheathed cable bodies one by one, and the sheathed cable bodies are penetrated and arranged in the corresponding cable threading holes; The inner protective sleeve is sealed and sleeved on the plurality of hollow support detection plates, the inner protective sleeve is provided with a plurality of detection through holes connected with the hollow support detection plates, a sealed cavity is formed between two adjacent hollow support detection plates and the inner protective sleeve, the skin-changing power assembly corresponds to the sealed cavity one by one, the skin-changing power assembly is located in the sealed cavity, the inner protective sleeve is provided with a plurality of sleeve-changing grooves, and one end of the skin-changing power assembly passes through the corresponding sleeve-changing groove; A plurality of anti-skid soft racks are arranged on the inner wall of the outer corrosion-resistant casing, and the anti-skid soft racks correspond to the sleeve-changing grooves one by one. The outer corrosion-resistant casing is slidably sleeved on the inner protective casing, and the anti-skid soft racks are located in the sleeve-changing grooves. The anti-skid soft racks are meshed with the skin-changing power assembly; The air intake assembly is arranged in communication with one side of the flexible square tube; The air outlet assembly is arranged in communication with the other side of the flexible square tube.

[0007] As a preferred technical solution of the present application, the skin-changing power assembly includes a power rotating rod, a power fan blade, a power worm, a power frame and a power worm gear; The power rotating rod penetrates and is rotatably arranged on the flexible square tube; The power fan blades are arranged on the power rotating rod, and the power fan blades are located in the flexible square tube; The power worm is arranged on a side of the power rotating rod away from the flexible square tube; The power frame is arranged on the outer surface of the flexible square tube; The power worm wheel is rotatably arranged on the power frame, the power worm wheel is meshed with the power worm, one end of the power worm wheel penetrates into the sleeve replacement groove, and the power worm wheel is meshed with the anti-slip soft rack.

[0008] On the basis of the above scheme, the air intake assembly comprises an air intake pipe, an air intake check valve and a quick-connect flange; One end of the air inlet pipe is sealed and connected to one side of the flexible square tube; The air intake check valve is arranged on the air intake pipe; The quick-connect flange is arranged at the other end of the air inlet pipe.

[0009] On the basis of the above scheme, the gas outlet assembly includes a gas outlet pipe and a gas outlet control part; The air outlet pipe is sealed and connected to the other end of the flexible square tube; The air outlet control unit is arranged in communication with the air outlet pipe at a side away from the flexible square tube, and is used for regulating the air pressure in the flexible square tube.

[0010] Further on the basis of the above scheme, the air outlet control unit includes an air control box, an exhaust pipe, an exhaust valve and an air pressure detection sensor; The air control box is connected to and arranged at one end of the air outlet pipe away from the flexible square tube; The exhaust pipe is connected and arranged on the air control box; The exhaust valve is arranged on the exhaust pipe; The air pressure detection sensor is installed on the air control box.

[0011] On the basis of the above scheme, sealant is filled between both sides of the outer corrosion-resistant sleeve and the inner protective sleeve, so that a detection cavity is formed between the inner protective sleeve and the outer corrosion-resistant sleeve.

[0012] The working principle and beneficial effects of the present invention are: 1. When the present invention is used in a harsh environment, the corrosion-resistant cable covered with the outer corrosion-resistant casing is placed in the corrosion-resistant environment, and multiple cable bodies with skin are electrically connected to corresponding power supply and use equipment respectively, and then the exhaust valve is closed, one end of the air inlet pipe is connected to the external air supply equipment, and the gas is slowly filled into the flexible square tube through the air supply device, and the gas pressure in the flexible square tube is detected by the air pressure detection sensor. As the air pressure in the flexible square tube continues to increase, the gas will enter the hollow support detection plate. As the air pressure in the hollow support detection plate increases, the gas will be filled between the inner protective casing and the outer corrosion-resistant casing through the detection through hole. During the long-term use of the cable body with skin, when the surface of the outer corrosion-resistant casing is damaged due to corrosion, the gas between the outer corrosion-resistant casing and the inner protective casing will be repelled through the damaged position. When the air pressure detection sensor detects that the air pressure in the flexible square tube is reduced, it proves that the outer corrosion-resistant casing has reached the upper limit of use. 2. In the present invention, when replacing the outer corrosion-resistant casing that has reached the upper limit of use, the exhaust valve is opened, the sealant filled between the outer corrosion-resistant casing and the inner protective casing is removed, and then gas is introduced into the flexible square tube through the external gas supply equipment. When the gas moves rapidly in the flexible square tube toward the direction of the gas outlet pipe, the flowing gas will drive the power fan blades to rotate, the rotation of the power fan blades will drive the power rotating rod to rotate, and the rotation of the power rotating rod will drive the power worm to rotate, and the rotation of the power worm will drive the power worm gear to rotate. When the power worm gear rotates, the power fan blades will rotate, and the power fan blades will rotate. The worm gear meshes with the anti-slip soft rack to drive the movement of the anti-slip soft rack. The movement of the anti-slip soft rack will drive the outer corrosion-resistant casing to move toward the direction of the air outlet pipe, so that the outer corrosion-resistant casing is separated from the inner protective casing. When replacing the discarded outer corrosion-resistant casing, a new outer corrosion-resistant casing is pre-installed on the air supply equipment, and the new outer corrosion-resistant casing is re-installed on the inner protective tube. The replacement of the outer corrosion-resistant casing can be achieved without replacing the skinned cable body, which can not only greatly improve the service life of the skinned cable body, but also greatly reduce the cost of replacement.

[0016] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

The power worm gear 13 is meshed with the power worm 11.

[0019] Specifically, when there is fast-flowing gas in the flexible square tube 2, the airflow drives the power blades 10 to rotate, the rotation of the power blades 10 drives the power rotating rod 9 to rotate, the rotation of the power rotating rod 9 drives the power worm 11 to rotate, and the rotation of the power worm 11 drives the power worm wheel 13 to rotate.

[0020] As mentioned above, there are multiple hollow support detection plates 3, and the multiple hollow support detection plates 3 are evenly sealed and connected and sleeved on the flexible square tube 2. Each hollow support detection plate 3 is provided with a cable threading hole 4, and the cable threading hole 4 corresponds to the sheathed cable body 1 one by one. The sheathed cable body 1 is arranged in the corresponding cable threading hole 4.

[0021] Among them, the inner protective sleeve 5 is sealed and sleeved on multiple hollow support detection plates 3. The inner protective sleeve 5 is provided with multiple detection through holes connected to the hollow support detection plates 3. A sealed cavity is formed between two adjacent hollow support detection plates 3 and the inner protective sleeve 5. The skin-changing power component 001 corresponds to the sealed cavity one by one. The skin-changing power component 001 is located in the sealed cavity. The inner protective sleeve 5 is provided with multiple sleeve-changing grooves 6. One end of the power worm gear 13 penetrates into the sleeve-changing groove 6, and the power worm gear 13 is meshed with the anti-slip soft rack 8. Multiple anti-slip soft racks 8 are arranged on the inner wall of the outer corrosion-resistant sleeve 7. The anti-slip soft racks 8 correspond to the sleeve-changing grooves 6 one by one. The outer corrosion-resistant sleeve 7 is slidably sleeved on the inner protective sleeve 5. The anti-slip soft rack 8 is located in the sleeve-changing groove 6. The anti-slip soft rack 8 is meshed with the skin-changing power component 001.

[0022] In the above, the air inlet component 002 is connected and arranged on one side of the flexible square tube 2, and the air outlet component 003 is connected and arranged on the other side of the flexible square tube 2. The air inlet component 002 includes an air inlet pipe 14, an air inlet check valve 15 and a quick-connect flange 16. One end of the air inlet pipe 14 is sealed and connected and arranged on one side of the flexible square tube 2. The air inlet check valve 15 is arranged on the air inlet pipe 14, and the quick-connect flange 16 is arranged on the other end of the air inlet pipe 14. The air outlet component 003 includes an air outlet pipe 17 and an air outlet control unit. The air outlet pipe 17 is sealed and connected and arranged on one side of the flexible square tube 2. Located at the other end of the flexible square tube 2, the air outlet control unit is connected and arranged on the side of the air outlet pipe 17 away from the flexible square tube 2, and is used to regulate the air pressure in the flexible square tube 2. The air outlet control unit includes an air control box 18, an exhaust pipe 19, an exhaust valve 20 and an air pressure detection sensor 21. The air control box 18 is connected and arranged on the end of the air outlet pipe 17 away from the flexible square tube 2, the exhaust pipe 19 is connected and arranged on the air control box 18, the exhaust valve 20 is arranged on the exhaust pipe 19, and the air pressure detection sensor 21 is installed on the air control box 18.

[0023] It is additionally explained that sealant is filled between both sides of the outer corrosion-resistant sleeve 7 and the inner protective sleeve 5 , so that a detection cavity is formed between the inner protective sleeve 5 and the outer corrosion-resistant sleeve 7 .

[0024] Specifically, when used in a harsh environment, the corrosion-resistant cable covered with the outer corrosion-resistant casing 7 is placed in a corrosion-resistant environment, and multiple cable bodies 1 with skins are electrically connected to corresponding power supply and use equipment respectively, and then the exhaust valve 20 is closed, and one end of the air inlet pipe 14 is connected to the external air supply equipment, and the gas is slowly filled into the flexible square tube 2 through the air supply setting, and the gas pressure in the flexible square tube 2 is detected by the air pressure detection sensor 21. As the air pressure in the flexible square tube 2 continues to increase, the gas It will enter the hollow support detection plate 3. As the air pressure in the hollow support detection plate 3 increases, the gas will be filled between the inner protective sleeve 5 and the outer corrosion-resistant sleeve 7 through the detection through hole. During the long-term use of the sheathed cable body 1, when the surface of the outer corrosion-resistant sleeve 7 is damaged due to corrosion, the gas between the outer corrosion-resistant sleeve 7 and the inner protective sleeve 5 will be repelled through the damaged position. When the air pressure detection sensor 21 detects that the air pressure in the flexible square tube 2 is reduced, it proves that the outer corrosion-resistant sleeve 7 has reached the upper limit of use.

[0025] Furthermore, when replacing the outer corrosion-resistant casing 7 that has reached its upper limit of use, the exhaust valve 20 is opened, the sealant filled between the outer corrosion-resistant casing 7 and the inner protective casing 5 is removed, and then gas is introduced into the flexible square tube 2 through the external gas supply equipment. When the gas moves rapidly in the flexible square tube 2 toward the direction of the gas outlet pipe 17, it drives the power worm gear 13 to rotate. When the power worm gear 13 rotates, the power worm gear 13 engages with the anti-skid soft rack 8 to drive the anti-skid soft rack 8 to move. The movement of 8 will drive the outer corrosion-resistant sleeve 7 to move toward the direction of the air outlet pipe 17, so that the outer corrosion-resistant sleeve 7 is separated from the inner protective sleeve 5. When the discarded outer corrosion-resistant sleeve 7 is replaced, the new outer corrosion-resistant sleeve 7 is pre-installed on the air supply equipment, and the new outer corrosion-resistant sleeve 7 is re-installed on the inner protective tube. The replacement of the outer corrosion-resistant sleeve 7 can be achieved without replacing the skinned cable body 1, which can not only greatly improve the service life of the skinned cable body 1, but also greatly reduce the cost of replacement.

[0026] 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.
