Description

Technical Field

[0001] The present invention belongs to the technical field of protective tubes, and in particular relates to a moisture-proof high-strength segmented cable protective tube. Background Art

[0002] A protective tube is a pipe used to protect cables, wires or other transmission media from physical damage and environmental factors. It is widely used in power systems, communication networks, industrial control and other fields. By selecting suitable materials such as plastic (PVC, PE), metal (stainless steel, galvanized steel) or composite materials, it can be ensured to adapt to different application environments and meet specific needs, such as pressure resistance, impact resistance, corrosion resistance and adaptability to temperature changes. At the same time, considering the convenience of installation, the design of the protective tube must also meet actual construction requirements. For example, the current main type of protective tube is segmented protective tube that can be assembled on site. During installation, it can be continuously assembled into different lengths as needed, which is very flexible to use.

[0003] When the protective tube used to protect the cable is used on an offshore platform-based observation station, the metal protective tube is easily affected by moisture and salty air, such as corrosion, water leakage at the joints, and water ingress after corrosion. The non-metallic protective tube has limited strength and poor heat dissipation performance. When the power of the cables or wires inside are large and the number is large, the protective tube assembled in continuous sections will be subject to great pressure, and it is impossible to ensure that the cables or wires can obtain good heat dissipation efficiency and support stability.

[0006] A moisture-proof, high-strength, segmented cable protection tube comprises a tube body, and also includes: a plurality of circumferentially distributed metal wires fixedly connected to the inner tube body and arranged parallel to the axis of the tube body, wherein both ends and the middle of the tube body are fixedly filled with reinforcement tubes, the material of the reinforcement tubes is the same as that of the metal wires, the axial end of the reinforcement tubes is provided with a through-hole, and the metal wires pass through the through-holes; a metal tube with annular grooves at both ends, the end of the tube body is inserted into the annular groove, and when multiple sections of the tube body and the metal tube are connected in series in sequence, a segmented cable protection tube is formed, wherein the outer wall of the metal tube is covered with an anti-rust layer, and the inner wall of the annular groove is fixedly installed with a sealing ring that fits the outer wall of the tube body, and the end of the tube body is connected to the metal tube by a locking part.

[0007] Preferably, the locking portion includes a socket arranged in the annular groove, the socket extends into the metal tube, and the end of the metal wire is inserted into the socket, wherein the outer wall of the metal tube is provided with a sliding hole connected to the socket, and a positioning pin is longitudinally slidably connected in the sliding hole, the outer wall of the metal wire is provided with a card groove, one end of the positioning pin is inserted in the card groove, the end of the positioning pin is provided with a first chamfer, the top of the positioning pin is fixedly connected to a top plate, and a tightening spring is installed between the top plate and the outer wall of the metal tube.

[0008] Preferably, the inner wall of the tube body is provided with a plurality of circumferentially distributed C-shaped tubes, the material of the C-shaped tubes is the same as that of the reinforcement tubes, one end of the C-shaped tubes is fixedly connected to the reinforcement tube in the middle of the tube body, and the other end of the C-shaped tubes forms an opening with the inner wall of the tube body.

[0009] Furthermore, a hanger is fixedly connected to the outer wall of the metal tube, a mounting plate is fixedly connected to the top of the hanger, and screw holes are provided on the mounting plate.

[0010] Furthermore, a hanging ring is fixedly connected to the reinforcing tube in the middle of the tube body, and a ring-shaped pull rope is sleeved on the hanging ring, and the other end of the ring-shaped pull rope is connected to the hanger.

[0011] Furthermore, the hanger is connected to an elastic vertical plate, the top of the elastic vertical plate is fixedly connected to a hook, and the other end of the ring-shaped pull rope is hung on the hook.

[0012] Furthermore, the outer wall of the metal tube is provided with a circular ring, the end of the circular ring is provided with a second chamfer facing the end of the positioning pin, and the elastic vertical plate is fixedly connected to the circular ring.

[0013] Furthermore, a horizontal frame is fixedly connected to the hanger, a horizontal hole is provided on the horizontal frame, and a guide column inserted into the horizontal hole is fixedly connected to the elastic vertical plate.

[0014] Furthermore, both axial ends of the C-shaped tube are fixedly connected with strip-shaped supporting plates, the axial cross-section of the strip-shaped supporting plates is in the shape of an arc, and the concave surface of the strip-shaped supporting plates is arranged upward.

[0015] Preferably, the length of the reinforcement tube is greater than the depth of the annular groove.

[0016] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0017] 1. The present invention ensures the sealing between the tube body and the metal tube through the sealing ring on the inner wall of the annular groove, thereby achieving the purpose of moisture-proofing. Since the metal wire and the reinforcing tube are provided in the tube body, the tube body used on the offshore platform-based observation station is not easy to rust while ensuring good supporting strength.

[0018] 2. The present invention inserts the end of the tube body into the annular groove and inserts the metal wire into the insertion hole, so that the positioning pin can be automatically inserted into the card slot. The positioning pin will limit the metal wire and fix the end of the tube body in the annular groove, thereby facilitating the assembly and fixation of the segmented protective tube.

[0019] 3. The present invention inserts multiple cables into multiple C-shaped tubes respectively, so that the multiple cables can be separated from each other, which can ensure the heat dissipation efficiency of the cables and are not easy to interfere with each other. On the other hand, when the cable power is large and generates more heat, the cable can transfer the heat to the metal wire, reinforcement tube, metal tube, hanger and mounting plate. Therefore, the metal wire, reinforcement tube, metal tube, hanger and mounting plate can assist in the heat dissipation of the cable, effectively ensuring the heat dissipation efficiency of the cable, making the use of the cable more stable, and reducing the probability of failure of equipment on the offshore platform-based observation station.

[0020] 4. The present invention pulls the free end of the ring-shaped pull rope and hangs it on a hook, so that the middle part of the tube body can be supported by the hook through the metal wire, and the hook can be supported by the hanger and the mounting plate. At this time, a stable triangular structure is formed between the ring-shaped pull rope, the elastic vertical plate and the tube body, which makes the middle part of the tube body less likely to sink and bend, thereby improving the support strength of the segmented protective tube.

[0021] 5. The present invention uses an elastic vertical plate to pull the ring to translate on the outer wall of the metal tube. The positioning pin will be pressed into the slot under the top pressure of the second chamfer, which can automatically realize the self-locking work of the positioning pin, making the positioning of the positioning pin on the metal wire more stable, thereby making the connection strength between the tube body and the metal tube higher.

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0035] Example 1: Reference Figures 1-9A moisture-proof high-strength segmented cable protection tube includes a tube body 1, which is made of rubber or plastic, and also includes: a plurality of circumferentially distributed metal wires 3, which are fixedly connected to the tube body 1 and arranged parallel to the axis of the tube body 1, wherein both ends of the tube body 1 and the middle thereof are fixedly filled with a reinforcing tube 2, the reinforcing tube 2 is made of the same material as the metal wire 3, and the metal wire 3 and the reinforcing tube 2 are made of steel or copper alloy with good thermal conductivity, the axial end of the reinforcing tube 2 is provided with a through hole 24, the metal wire The metal wire 3 passes through the through-hole 24; a metal tube 5 is provided with annular grooves 7 at both ends, the material of the metal tube 5 is the same as that of the metal wire 3, the end of the tube body 1 is inserted into the annular groove 7, and when multiple sections of the tube body 1 and the metal tube 5 are connected in series in sequence, a segmented cable protection tube is formed, wherein the outer wall of the metal tube 5 is covered with an anti-rust layer 6, the material of the anti-rust layer 6 is the same as that of the tube body 1, and the inner wall of the annular groove 7 is fixedly installed with a sealing ring 8 that fits the outer wall of the tube body 1, and the end of the tube body 1 is connected to the metal tube 5 by a locking portion.

[0036] Specifically, when in use, first fix the metal tube 5 on the top of the wall, and then insert the end of the tube body 1 into the annular groove 7. At this time, the end of the tube body 1 can be fixed in the annular groove 7 through the locking part. When a longer protective tube needs to be connected, multiple groups of metal tubes 5 and tube bodies 1 are installed in sequence and continuously to form a continuous segmented metal protective tube, which facilitates the assembly and fixation of the segmented protective tube and is more convenient to use. After the fixation is completed, the sealing ring 8 on the inner wall of the annular groove 7 will ensure the sealing between the tube body 1 and the metal tube 5, so that the segmented tube body 1 can achieve good moisture-proofing. Since the metal wire 3 and the reinforcing tube 2 are provided in the tube body 1, the tube body 1 used on the offshore platform-based observation station can not easily rust while ensuring good supporting strength.

[0037] The outer wall of the metal tube 5 is fixedly connected with a hanger 19, and the top of the hanger 19 is fixedly connected with a mounting plate 18. The hanger 19 and the mounting plate 18 are made of alloy steel that is not easy to rust, such as stainless steel, and screw holes are opened on the mounting plate 18.

[0038] Specifically, when in use, the mounting plate 18 can be fixed to the wall by passing the screws through the screw holes and then fixing the screws to the wall.

[0039] The length of the above-mentioned reinforcement tube 2 is greater than the depth of the annular groove 7. Therefore, after the end of the tube body 1 is inserted into the annular groove 7, the reinforcement tube 2 can ensure the supporting strength of the tube body 1 in the annular groove 7, prevent the low hardness of the end of the tube body 1 from affecting the connection strength between the two, and thus ensure that the entire segmented protective tube has better supporting strength.

[0040] Example 2: Reference Figure 5-Figure 7, a moisture-proof high-strength segmented cable protection tube, which is basically the same as Example 1, and further comprises:

[0041] The above-mentioned locking portion includes a socket 9 arranged in the annular groove 7, the socket 9 passes through the metal tube 5, the end of the metal wire 3 is inserted into the socket 9, and the metal wire 3 has the same diameter as the socket 9, wherein the outer wall of the metal tube 5 is provided with a sliding hole 10 connected to the socket 9, and a positioning pin 11 is longitudinally slidably connected in the sliding hole 10, and the outer wall of the metal wire 3 is provided with a card groove 25, one end of the positioning pin 11 is inserted in the card groove 25, and the end of the positioning pin 11 is provided with a first chamfer 12, and the top of the positioning pin 11 is fixedly connected to a top plate 14, and a tightening spring 13 is installed between the top plate 14 and the outer wall of the metal tube 5.

[0042] Specifically, when connecting the tube body 1 to the metal tube 5, the end of the tube body 1 is inserted into the annular groove 7, and the metal wire 3 is inserted into the socket 9. During the insertion, due to the setting of the first chamfer 12, the metal wire 3 will push the positioning pin 11 away from the socket 9 through its end. When the slot 25 is aligned with the positioning pin 11, the tightening spring 13 will drive the top plate 14 and the positioning pin 11 to slide in the opposite direction and reset. The positioning pin 11 can be automatically inserted into the slot 25, and the positioning pin 11 will limit the metal wire 3, so that the end of the tube body 1 can be fixed in the annular groove 7, thereby facilitating the assembly and fixation of the segmented protective tube, and it will be more convenient to use, especially when used in complex installation environments such as offshore platform-based observation stations.

[0043] Example 3: Reference Figure 3 、 Figure 8 as well as Figure 9 , a moisture-proof high-strength segmented cable protection tube, which is basically the same as Example 2, and further comprises:

[0044] The inner wall of the above-mentioned tube body 1 is provided with a plurality of circumferentially distributed C-shaped tubes 4. The material of the C-shaped tube 4 is the same as that of the reinforcing tube 2. One end of the C-shaped tube 4 is fixedly connected to the reinforcing tube 2 in the middle of the tube body 1, and the other end of the C-shaped tube 4 forms an opening 29 with the inner wall of the tube body 1. The C-shaped tube 4 is elastic. The setting of the opening 29 can facilitate the fixation of the cable, so that the outer wall of the cable fits more closely with the inner wall of the C-shaped tube 4.

[0045] When laying cables or wires, multiple cables are inserted into multiple C-shaped tubes 4 respectively, so that the multiple cables can be separated from each other, which can ensure the heat dissipation efficiency of the cables and are not easily interfered with each other. Since the C-shaped tube 4 is fixedly connected to the reinforcing tube 2, the supporting strength of the C-shaped tube 4 in the tube body 1 can be guaranteed. On the other hand, when the cable power is large and generates more heat, the cable can transfer the heat to the C-shaped tube 4, and the C-shaped tube 4 can transfer the heat to the reinforcing tube 2 and the metal wire 3, and the metal wire 3 can transfer the heat to the metal tube 5, the hanger 19 and the mounting plate 18, so the metal The metal wire 3, reinforcing tube 2, metal tube 5, hanger 19 and mounting plate 18 can all assist in heat dissipation of the cable, effectively ensuring the heat dissipation efficiency of the cable, making the use of the cable more stable, and reducing the probability of failure of equipment on the offshore platform-based observation station; and when the metal tube 5 is heated, the metal tube 5 will heat the sealing ring 8 in the annular groove 7, which can cause the sealing ring 8 to expand, thereby improving the sealing performance of the sealing ring 8, and can make the moisture in the annular groove 7 evaporate in time, making it difficult for moisture to enter the tube body 1 through the annular groove 7, thereby also improving the moisture-proof performance of the segmented protective tube.

[0046] Both axial ends of the C-shaped tube 4 are fixedly connected with strip-shaped supporting plates 23 . The axial cross-section of the strip-shaped supporting plate 23 is in the shape of an arc, and the concave surface of the strip-shaped supporting plate 23 is arranged upward.

[0047] Specifically, when laying the cable, the cable can be inserted into the C-shaped tube 4 along the strip support plate 23, thereby facilitating the laying of the cable, and the strip support plate 23 can also effectively support and dissipate heat for the cable, making the cable more stable and able to efficiently transfer heat to the metal wire 3, reinforcing tube 2, metal tube 5, hanger 19 and mounting plate 18.

[0048] Example 4: Reference Figure 1-Figure 2 as well as Figure 4-Figure 7 , a moisture-proof high-strength segmented cable protection tube, which is basically the same as Example 3, and further comprises:

[0049] A hanging ring 16 is fixedly connected to the reinforcing tube 2 in the middle of the above-mentioned tube body 1, and a ring-shaped pull rope 17 is sleeved on the hanging ring 16, and the other end of the ring-shaped pull rope 17 is connected to the hanger 19; an elastic vertical plate 20 is connected to the hanger 19, and the elastic vertical plate 20 is elastic. A hook 21 is fixedly connected to the top of the elastic vertical plate 20, and the other end of the ring-shaped pull rope 17 is hung on the hook 21; the outer wall of the metal tube 5 is sleeved with a circular ring 15, and the end of the circular ring 15 is provided with a second chamfer 26 facing the end of the positioning pin 11, and the elastic vertical plate 20 is fixedly connected to the circular ring 15.

[0050] Specifically, after installing the tube body 1, pull the free end of the annular pull rope 17 and hang it on the hook 21. At this time, the elastic vertical plate 20 can elastically tighten the annular pull rope 17 through the hook 21, so that the middle part of the tube body 1 can be supported by the hook 21 through the metal wire 3, and the hook 21 can be supported by the hanger 19 and the mounting plate 18. At this time, a stable triangular structure is formed between the annular pull rope 17, the elastic vertical plate 20 and the tube body 1, so that the middle part of the tube body 1 is not easy to sink and bend, so that the support strength of the segmented protection can be better.

[0051] When the annular pull rope 17 is hung on the hook 21, the hook 21 will pull the circular ring 15 to translate on the outer wall of the metal tube 5 through the elastic vertical plate 20. The circular ring 15 will press the second chamfer 26 against the end of the positioning pin 11. The positioning pin 11 will be pressed into the groove 25 under the pressure of the second chamfer 26. In this way, the self-locking work of the positioning pin 11 can be automatically achieved, making the positioning of the positioning pin 11 on the metal wire 3 more stable, thereby making the connection strength between the tube body 1 and the metal tube 5 higher.

[0052] The above-mentioned hanger 19 is fixedly connected to a horizontal frame 22, and a horizontal hole 27 is provided on the horizontal frame 22. The elastic vertical plate 20 is fixedly connected to a guide column 28 inserted into the horizontal hole 27. Therefore, when the hook 21 is pulled by the annular pull rope 17, the elastic vertical plate 20 can drive the guide column 28 to slide in the horizontal hole 27, so that the movement of the elastic vertical plate 20 is well guided.

[0053] When the present invention is in use, first fix the mounting plate 18 to the top of the wall by screws, then insert the end of the tube body 1 into the annular groove 7, and insert the metal wire 3 into the insertion hole 9. During the insertion, due to the setting of the first chamfer 12, the metal wire 3 will push the positioning pin 11 away from the insertion hole 9 through its end. When the slot 25 is aligned with the positioning pin 11, the pressing spring 13 will drive the top plate 14 and the positioning pin 11 to slide back and forth in the opposite direction, and the positioning pin 11 can be automatically inserted into the slot 25. The positioning pin 11 will limit the metal wire 3, and the end of the tube body 1 can be fixed in the annular groove 7. When it is necessary to connect a longer protective tube, the metal wire 3 is connected in sequence. By continuously installing multiple groups of metal tubes 5 and tube bodies 1, they can be combined into a continuous segmented metal protective tube, which facilitates the assembly and fixation of the segmented protective tube and is more convenient to use. The connection strength between the tube body 1 and the metal tube 5 can be guaranteed by the connection method of the positioning pin 11 and the metal wire 3; and after the fixation is completed, the sealing ring 8 on the inner wall of the annular groove 7 will ensure the sealing between the tube body 1 and the metal tube 5, so that the segmented tube body 1 can achieve the purpose of good moisture-proofing. Since the metal wire 3 and the reinforcing tube 2 are provided in the tube body 1, the tube body 1 can be less likely to rust while ensuring good supporting strength.

[0054] When laying cables or wires, multiple cables are inserted into multiple C-shaped tubes 4 respectively, so that the multiple cables can be separated from each other, which can ensure the heat dissipation efficiency of the cables and are not easily interfered with each other. Since the C-shaped tube 4 is fixedly connected to the reinforcement tube 2, the supporting strength of the C-shaped tube 4 in the tube body 1 can be guaranteed. On the other hand, when the cable power is large and generates more heat, the cable can transfer the heat to the C-shaped tube 4, and the C-shaped tube 4 can transfer the heat to the reinforcement tube 2 and the metal wire 3, and the metal wire 3 can transfer the heat to the metal tube 5, the hanger 19 and so on. and the mounting plate 18, so the metal wire 3, the reinforcing tube 2, the metal tube 5, the hanger 19 and the mounting plate 18 can all assist in dissipating the heat of the cable, effectively ensuring the heat dissipation efficiency of the cable and making the use of the cable more stable; and when the metal tube 5 is heated, the metal tube 5 will heat the sealing ring 8 in the annular groove 7, which can make the sealing ring 8 expand, improve the sealing performance of the sealing ring 8, and make the moisture in the annular groove 7 evaporate in time, so that moisture is not easy to enter the tube body 1 through the annular groove 7, thereby improving the moisture-proof performance of the segmented protective tube.

[0055] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with the present invention can make slight changes or modifications to equivalent embodiments using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
