Description

Technical Field

[0001] This invention relates to the field of MPP pipe technology, specifically to an MPP power cable protection pipe with a quick-connect structure. Background Technology

[0002] MPP power cable protection pipe is a type of pipe made of modified polypropylene (MPP) material, primarily used for the protection of power cables. It boasts excellent corrosion resistance, high-temperature resistance, and pressure resistance, making it suitable for underground installation in various harsh environments. MPP power cable protection pipes not only effectively prevent cables from external mechanical damage but also effectively isolate the cables from harmful substances in the soil, extending the cable's service life. Furthermore, it is lightweight, easy to install, environmentally friendly, and durable, and is widely used in the power and telecommunications industries.

[0003] Chinese patent publication number CN220139176U discloses an MPP power cable protection pipe with a quick-connect structure, comprising two MPP pipes, each with a semi-circular sleeve fixedly mounted on its surface. The ends of the MPP pipes are located in the middle of the semi-circular sleeves, and mounting plates are mounted on the surfaces of the two semi-circular sleeves. This patent describes an MPP power cable protection pipe with a quick-connect structure that, by setting up MPP pipes, wedges, and grooves, interlocks the two MPP pipes together. The wedges abut against the inside of the grooves. When the two mounting plates are installed, they need to be aligned, and the inclined edges of the grooves and wedges of the wedges press against each other, causing the two MPP pipes to move closer together. Finally, a fixed assembly is used for installation, ensuring a tighter connection between the two MPP pipes, a safer installation method, and simpler operation.

[0004] However, current power cable protection pipes have the following problems: when the cable passes through the connection between power cable protection pipe one and power cable protection pipe two, the cable will move in a serpentine manner during the movement. Therefore, the serpentine cable will cause the cable at the connection between power cable protection pipe one and power cable protection pipe two to continuously hit the connection, which will cause the connection between power cable protection pipe one and power cable protection pipe two to loosen. Therefore, we propose an MPP power cable protection pipe with a quick-connect structure. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an MPP power cable protection pipe with a quick-connect structure, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an MPP power cable protection pipe with a quick-connect structure, comprising a power cable protection pipe I and a power cable protection pipe II. A protection pipe connecting seat I is fixed to the outer wall of the power cable protection pipe I, and a protection pipe connecting seat II is fixed to the outer wall of the power cable protection pipe II. The protection pipe connecting seat I and the protection pipe connecting seat II are connected by bolts. Anti-distraction devices are provided on the sides of the protection pipe connecting seat I and the protection pipe connecting seat II that are far apart from each other. Each anti-distraction device includes two sets of hollow blocks, which are respectively fixed to the protection pipe connecting seat I and the protection pipe connecting seat II. On the side of the pipe connector two that are far apart from each other, a movable block is slidably connected to the inner wall of the hollow block, and a fixed ring plate is fixed to the outer wall of the movable block. A convex ring block is fixed to the outer wall of the fixed ring plate on the side of the protective pipe connector one, and a concave ring block is fixed to the outer wall of the fixed ring plate on the side of the power cable protective pipe two. An abutting long block is fixed to the inner wall of both the convex and concave ring blocks. A supporting long block is fixed to the bottom of the hollow block. A rotating rod is rotatably installed on the side of the supporting long block. A pressure block is fixed to the end of the rotating rod away from the supporting long block. A round block is fixed to the side of the pressure block. A torsion spring is provided between the pressure block and the supporting long block.

[0007] According to the above technical solution, the outer wall of the convex ring block is fixed with a first oblique ring, and the outer wall of the concave ring block is fixed with a second oblique ring.

[0008] According to the above technical solution, the abutting long block is located on one side of the fixed ring plate with an arc surface, and the circular block is located on the displacement trajectory of the arc surface side of the abutting long block.

[0009] According to the above technical solution, an anti-deviation device is provided on the side of the concave ring block away from the convex ring block. The anti-deviation device includes a fixed ring block, which is fixed on the side of the concave ring block away from the convex ring block. A second movable groove is opened on the side of the fixed ring block. An L-shaped rod is slidably installed on the inner wall of the second movable groove. A triangular insert is fixed at the end of the L-shaped rod away from the second movable groove. A rotating ring is rotatably installed on the side of the fixed ring block. An arc-shaped groove is opened on the side of the rotating ring to allow the L-shaped rod to move along the second movable groove away from the second power cable protection pipe. Multiple short rods are fixed on the side of the rotating ring.

[0010] According to the above technical solution, a movable groove is provided on the side of the fixed ring block, an L-shaped rod is slidably installed on the inner wall of the movable groove, a support block is fixed at the end of the L-shaped rod away from the movable groove, and an arc-shaped groove is provided on the side of the rotating ring to compress the L-shaped rod along the movable groove to the power cable protection pipe.

[0011] According to the above technical solution, the support block is in contact with the two phases of the power cable protection pipe.

[0012] According to the above technical solution, the inner wall of the concave ring block is provided with a locking device. The locking device includes a long rod, the outer wall of which is slidably installed on the inner wall of the concave ring block. One end of the long rod is fixed with a movable ring, and a spring is provided between the movable ring and the concave ring block.

[0013] According to the above technical solution, the moving ring is located on the displacement trajectory of the convex part of the convex ring block, and the fixed ring block, the rotating ring, and the short rod are all provided with slots to allow the long rod to move.

[0014] This invention provides an MPP power cable protection pipe with a quick-connect structure. It has the following advantages:

[0015] (1) Through the setting of the anti-random movement device, the present invention, with the cooperation of hollow block, moving block, fixed ring plate, convex ring block, concave ring block, abutting long block, supporting long block, rotating rod, pressure block, and round block, the rotation of the pressure block will cause the power cable protection pipe one and power cable protection pipe two to deform, thereby pressing the cables inside the power cable protection pipe one and power cable protection pipe two, thereby preventing the cables in other parts from moving in a serpentine state during the movement, and the serpentine moving cables will cause the cables at the connection between power cable protection pipe one and power cable protection pipe two to keep hitting each other. The impact on the connection between power cable protection pipe one and power cable protection pipe two caused the connection to loosen. Simultaneously, with the cooperation of inclined ring one, inclined ring two, convex ring block, and concave ring block, when workers cover the connection between power cable protection pipe one and power cable protection pipe two with soil, the soil, upon contact with the conical surface of the conical ring, will disperse to both sides, thus preventing the soil from acting on the connection between power cable protection pipe one and power cable protection pipe two and causing damage to the connection.

[0016] (2) By setting up an anti-deviation device, the triangular plug that contacts the bottom of the pit is inserted into the soil under the cooperation of the fixed ring block, rotating ring, short rod, moving groove two, L-shaped rod two, triangular plug block, and arc groove two. This avoids the cable from deviating from the predetermined position when it passes through the power cable protection pipe one and power cable protection pipe two due to the cable being dragged and moving in a serpentine state. At the same time, under the cooperation of the fixed ring block, moving groove one, L-shaped rod one, support block, rotating ring, arc groove one, and short rod, the movement of L-shaped rod one will drive the support block to squeeze the power cable protection pipe two, so that the internal gap of the power cable protection pipe two can just pass through the cable, thereby reducing the problem of the cable shaking at the connection between the power cable protection pipe one and power cable protection pipe two.

[0017] (3) By setting the locking device, the present invention enables the long rod, the moving ring, the short rod, the rotating ring, the fixed ring block, the convex ring block, and the concave ring block to work together. The convex part of the convex ring block will push the moving ring to move and squeeze the spring. The moving ring will enter the groove of the short rod, the rotating ring, and the fixed ring block, thereby fixing the short rod, the rotating ring, and the fixed ring block, thus ensuring the stability of the short rod and the rotating ring.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Please see Figure 1 - Figure 8 One embodiment of the present invention is: an MPP power cable protection pipe with a quick-connect structure, comprising a power cable protection pipe one 1 and a power cable protection pipe two 2. A protection pipe connector one 11 is fixed to the outer wall of the power cable protection pipe one 1, and a protection pipe connector two 21 is fixed to the outer wall of the power cable protection pipe two 2. The protection pipe connector one 11 and the protection pipe connector two 21 are connected by bolts. Anti-distraction devices 3 are provided on the sides of the protection pipe connector one 11 and the protection pipe connector two 21 that are far apart from each other. The system includes two sets of hollow blocks 31, which are respectively fixed on opposite sides of the protective pipe connector 11 and the protective pipe connector 21. A movable block 32 is slidably connected to the inner wall of each hollow block 31. A fixing ring plate 33 is fixed to the outer wall of the movable block 32. A convex ring block 34 is fixed to the outer wall of the fixing ring plate 33 on the side of the protective pipe connector 11, and a concave ring block 341 is fixed to the outer wall of the fixing ring plate 33 on the side of the power cable protective pipe 21. Both the convex ring block 34 and the concave ring block 341 have abutting lengths fixed to their inner walls. Block 35, a supporting long block 36 is fixed to the bottom of the hollow block 31, a rotating rod 37 is rotatably mounted on the side of the supporting long block 36, a pressure block 38 is fixed to the end of the rotating rod 37 away from the supporting long block 36, a round block 39 is fixed to the side of the pressure block 38, a torsion spring is provided between the pressure block 38 and the supporting long block 36, the contact long block 35 is located on one side of the fixed ring plate 33 with an arc surface, the round block 39 is located on the displacement trajectory of the arc surface side of the contact long block 35. Through the above structure, the rotation of the pressure block 38 will cause the power cable protection pipe 1 to contact the power cable. The deformation of the second power cable protection pipe 2 compresses the cables inside the first power cable protection pipe 1 and the second power cable protection pipe 2, thereby preventing other parts of the cable from moving in a serpentine manner during the process. Furthermore, the serpentine movement of the cable causes the cable at the connection point between the first power cable protection pipe 1 and the second power cable protection pipe 2 to continuously collide with the connection point, which would lead to the problem of the connection point between the first power cable protection pipe 1 and the second power cable protection pipe 2 becoming loose.

[0029] The outer wall of the convex ring block 34 is fixed with an oblique ring 310, and the outer wall of the concave ring block 341 is fixed with an oblique ring 311. With the above structure, when workers cover the connection between the power cable protection pipe 1 and the power cable protection pipe 2, the soil will be dispersed to both sides when it comes into contact with the conical surface of the conical ring, thereby avoiding the problem of soil acting on the connection between the power cable protection pipe 1 and the power cable protection pipe 2, which would cause damage to the connection between the power cable protection pipe 1 and the power cable protection pipe 2.

[0030] An anti-deviation device 4 is provided on the side of the concave ring block 341 away from the convex ring block 34. The anti-deviation device 4 includes a fixed ring block 41, which is fixed on the side of the concave ring block 341 away from the convex ring block 34. A second moving groove 48 is provided on the side of the fixed ring block 41. An L-shaped rod 49 is slidably installed on the inner wall of the second moving groove 48. A triangular insert 410 is fixed to one end of the L-shaped rod 49 away from the second moving groove 48. A rotating ring 45 is rotatably installed on the side of the fixed ring block 41. The side of the rotating ring 45 has a feature that allows the L-shaped rod to rotate. Rod 49 moves along the moving groove 48 away from the power cable protection pipe 2. The arc groove 411 is fixed on the side of the rotating ring 45. Through the above structure, the triangular plug 410 that contacts the bottom of the pit is inserted into the soil, thereby avoiding the power cable protection pipe 1 and power cable protection pipe 2 from deviating from the predetermined position when the cable passes through the inside of the power cable protection pipe 1 and power cable protection pipe 2 due to the cable being dragged in a serpentine movement.

[0031] The fixed ring block 41 has a movable groove 42 on its side. An L-shaped rod 43 is slidably installed on the inner wall of the movable groove 42. A support block 44 is fixed to the end of the L-shaped rod 43 away from the movable groove 42. The rotating ring 45 has an arc-shaped groove 46 on its side, which causes the L-shaped rod 43 to press against the power cable protection tube 2 along the movable groove 42. The support block 44 is in contact with the power cable protection tube 2. With the above structure, the movement of the L-shaped rod 43 will drive the support block 44 to press against the power cable protection tube 2, so that the internal gap of the power cable protection tube 2 can just pass through the cable, thereby reducing the problem of the cable shaking at the connection between the power cable protection tube 1 and the power cable protection tube 2.

[0032] In use, the worker aligns the connecting seat 11 on the power cable protection pipe 1 with the connecting seat 21 on the power cable protection pipe 2, and then fixes the connecting seat 11 and the connecting seat 21 with bolts and nuts, thus achieving a quick connection between the power cable protection pipe 1 and the power cable protection pipe 2. The connected power cable protection pipe 1 and power cable protection pipe 2 are then placed in the dug pit. When the cable passes through the connection point of the power cable protection pipe 1 and power cable protection pipe 2, due to the cable's movement... During the movement, the cable will move in a serpentine pattern. This serpentine movement causes the cable at the connection point between power cable protection pipe 1 and power cable protection pipe 2 to repeatedly impact this connection, potentially leading to loosening. Therefore, after the cable passes through the connection point of power cable protection pipe 1 and power cable protection pipe 2, the operator moves the convex ring block 34 and the concave ring block 341 respectively, thereby loosening the connection between the convex ring block 34 and the concave ring block 341. The concave ring blocks 341 drive their respective fixed ring plates 33 and moving blocks 32 to move closer together along the inner wall of the hollow block 31, so that the convex part of the convex ring block 34 enters the inner wall of the groove of the concave ring block 341. At the same time, when the convex ring block 34 and the concave ring block 341 move, they will both drive the abutting long block 35 to move. The movement of the abutting long block 35 will abut against the round block 39, so that the round block 39 drives the pressure block 38 and the rotating rod 37 to rotate along the side of the supporting long block 36, and causes the torsion spring to deform. The rotation will cause the power cable protection pipe 1 and the power cable protection pipe 2 to deform, thereby pressing the cables inside the power cable protection pipe 1 and the power cable protection pipe 2. This will prevent the cables in other parts from moving in a serpentine manner during the movement. Furthermore, the serpentine movement of the cables will cause the cables at the connection between the power cable protection pipe 1 and the power cable protection pipe 2 to continuously hit the connection between the power cable protection pipe 1 and the power cable protection pipe 2, which would lead to the problem of the connection between the power cable protection pipe 1 and the power cable protection pipe 2 becoming loose.When the convex ring block 34 and the concave ring block 341 move, the movement of the convex ring block 34 will cause the first inclined ring 310 to move, and the movement of the concave ring block 341 will cause the second inclined ring 311 to move. Therefore, after the convex ring block 34 and the concave ring block 341 are interlocked, the straight surfaces of the first inclined ring 310 and the second inclined ring 311 will come into contact with each other, thus forming a conical ring. Therefore, when workers cover the connection between the first power cable protection pipe 1 and the second power cable protection pipe 2 with soil, the soil will disperse to both sides upon contact with the conical surface of the conical ring, thereby preventing the soil from acting on the connection between the first power cable protection pipe 1 and the second power cable protection pipe 2, which could lead to damage to the connection between the first power cable protection pipe 1 and the second power cable protection pipe 2.

[0033] After placing the power cable protection pipe 1 and power cable protection pipe 2 into the dug pit, and before passing the cable through them, the worker rotates the rotating ring 45 using the short rod 47. The rotation of the rotating ring 45 causes the arc-shaped groove 411 to rotate, which in turn causes the L-shaped rod 49 to move along the inner wall of the arc-shaped groove 411. Simultaneously, the L-shaped rod 49 moves along the inner wall of the moving groove 48 in a direction away from the power cable protection pipe 2. This movement of the L-shaped rod 49 drives the triangular insert 410, causing the triangular insert 410, which is in contact with the bottom of the pit, to insert into the soil. This prevents the cable from being dragged when passing through the power cable protection pipes 1 and 2. When the device is in a serpentine movement, the power cable protection pipe 1 and the power cable protection pipe 2 deviate from their predetermined positions. Simultaneously with the rotation of the rotating ring 45, the rotation of the rotating ring 45 causes the arc-shaped groove 46 to rotate. The rotation of the arc-shaped groove 46 causes the L-shaped rod 43 to move along the inner wall of the arc-shaped groove 46. While the L-shaped rod 43 moves along the inner wall of the arc-shaped groove 46, it also moves along the inner wall of the moving groove 42 towards the power cable protection pipe 2. The movement of the L-shaped rod 43 causes the support block 44 to press against the power cable protection pipe 2, ensuring that the internal gap of the power cable protection pipe 2 allows the cable to pass through, thus reducing the problem of the cable swaying at the connection point between the power cable protection pipe 1 and the power cable protection pipe 2.

[0034] It should be noted that when it is necessary to excavate the power cable protection pipe 1 and the power cable protection pipe 2, the staff will use an external cleaning device to clean the soil in the arc-shaped groove 46 and the arc-shaped groove 411.

[0035] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, a locking device 5 is provided on the inner wall of the concave ring block 341. The locking device 5 includes a long rod 51. The outer wall of the long rod 51 is slidably installed on the inner wall of the concave ring block 341. A moving ring 52 is fixed at one end of the long rod 51. A spring is provided between the moving ring 52 and the concave ring block 341. The moving ring 52 is located on the displacement trajectory of the convex part of the convex ring block 34. The fixed ring block 41, the rotating ring 45, and the short rod 47 are all provided with slots for the long rod 51 to move. With the above structure, the movement of the moving ring 52 will enter the slots of the short rod 47, the rotating ring 45, and the fixed ring block 41, thereby fixing the short rod 47, the rotating ring 45, and the fixed ring block 41, thus ensuring the stability of the short rod 47 and the rotating ring 45.

[0036] In use, when the cable passes through the connection between the power cable protection pipe 1 and the power cable protection pipe 2, the operator uses the short rod 47 to rotate the rotating ring 45 in the opposite direction, thereby resetting the L-shaped rod 43 and the L-shaped rod 49. After resetting, the slots of the short rod 47, the rotating ring 45, and the fixed ring block 41 are on the same horizontal plane. At this time, when the convex ring block 34 and the concave ring block 341 are inserted into each other, the convex part of the convex ring block 34 will push the moving ring 52 to move and squeeze the spring. The movement of the moving ring 52 will enter the slots of the short rod 47, the rotating ring 45, and the fixed ring block 41, thereby fixing the short rod 47, the rotating ring 45, and the fixed ring block 41, thus ensuring the stability of the short rod 47 and the rotating ring 45.

[0037] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
