Description

Technical Field

[0001] This invention relates to the field of power pipe technology, specifically an MPP power pipe that is easy to assemble and connect. Background Technology

[0002] MPP power conduits are commonly used protective conduits in power transmission engineering and are widely used in underground cable laying scenarios. The underground construction environment is complex, and problems such as poor pit flatness and placement misalignment caused by the weight of the conduits are common, which bring many inconveniences to the docking and assembly of MPP power conduits.

[0003] In existing MPP power pipe connection technologies, the mainstream connection methods include flange connection, hot melt welding connection, and simple snap-fit ​​connection. Among them, flange connection and hot melt welding connection both require the use of external auxiliary tools for precise alignment and leveling. This not only requires multiple construction workers to work together, but also makes the alignment adjustment process cumbersome, which seriously affects the construction efficiency. At the same time, hot melt welding has high requirements for the construction environment temperature and operation skills. If the welding parameters are not properly controlled, defects such as incomplete welds and missing welds are likely to occur. While simple snap-fit ​​connections do not require complex auxiliary tools, their structural design is simplistic, typically allowing only a single locking action. Furthermore, once locked, the angle cannot be fine-tuned. If there is a slight angular deviation in the initial connection, it can easily lead to uneven force on the snap-fit. During long-term use, factors such as soil settlement can easily cause locking failure and pipe detachment. Therefore, this invention provides an MPP power pipe that is easy to assemble and connect, in order to solve the aforementioned problems. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. When using the power conduit of the present invention, the clamp connector is equipped with a bendable and deformable adjustment ring and a retaining ring plate that can change with the angle of the adjustment ring. With the synchronous linkage structure between the retaining ring plate and the plug rod, when two sets of power conduits are connected, the plug connector can achieve adaptive alignment by adjusting the angle of the retaining ring plate. There is no need to use external auxiliary tools such as a level for initial leveling. The construction personnel only need to insert the plug connector of one set of power conduits into the clamp connector of another set of power conduits to complete the initial alignment. The horizontal adjustment of alignment can be carried out in subsequent operations, which can effectively achieve a simple connection effect and avoid the problem of uneven clamp force caused by angle deviation.

[0014] 2. When using the power pipe of the present invention, a segmented locking and adjustment mechanism is used. In the initial locking stage, the initial fastener and the initial locking component work together in a one-way limiting manner to temporarily fix the two sets of power pipes, while retaining space for fine-tuning the angle. In the horizontal adjustment stage, the "whether the limiting block moves into the movable hole" is used as a visual judgment standard to ensure that the two sets of power pipes are accurately aligned. In the final locking stage, the adjustment component drives the plug rod to move, realizing the double locking of the final fastener auxiliary component and the initial locking component, and the final fastener main component and the final locking component. With the rigid limiting of the limiting block and the movable hole, the angular deviation and axial movement of the pipe are completely restricted, so that it can be effectively adjusted after docking. It can also effectively ensure the alignment of the two sets of power pipes. Compared with the existing single snap-fit ​​connection, this multi-locking structure has significantly improved resistance to soil settlement and vibration, higher locking stability, and effectively avoids the locking failure problem that occurs during long-term use.

[0015] 3. When the power pipe of the present invention is used, the condensate is collected through the liquid guide groove, and the pressure deformation of the liquid blocking plate is used to realize the one-way discharge of the condensate. At the same time, the limiting effect of the baffle strip on the liquid blocking plate prevents the seepage liquid in the backfill soil from invading the pipe inside in reverse, which greatly reduces the cable corrosion problem caused by the accumulation of condensate and the intrusion of seepage liquid, and significantly extends the service life of the cable and the safety of power transmission.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-10 In this embodiment of the invention, an MPP power pipe that is easy to assemble and connect includes a main pipe 1, on which pipe supports 2 are fixedly installed at intervals. One end of the pipe support 2 is equipped with a clamping connector 3, and the other end of the pipe support 2 is equipped with a plug connector 4. The two sets of power pipes can be connected by inserting the plug connector 4 on one set of power pipes into the clamping connector 3 on the other set of power pipes.

[0029] The connector 4 includes a tube 17, which is fixedly installed on the outer wall of the main tube 1. A preliminary locking assembly and a final locking assembly are installed on the tube 17. The snap-fit ​​connector 3 includes a base ring 5, which is fixedly connected to the main tube 1. An adjusting ring 14 is fixedly installed at the end of the base ring 5 away from the main tube 1. The adjusting ring 14 is a bendable annular block. A retaining plate 15 is fixedly installed at the end of the adjusting ring 14 away from the base ring 5. The retaining plate 15 can be bent and adjusted by the adjusting ring 14 and the base ring 5. The connector 4 is inserted into the inner side of the retaining plate 15. A rod assembly is installed on the inner side of the base ring 5. An adjusting assembly is also installed on the base ring 5. The adjusting assembly and the rod assembly are movably connected to each other. Next, the plug rod assembly extends into the buckle plate 15, and can be driven by the adjustment component to insert into the initial locking component and the final locking component on the plug connector 4. In the initial state, the adjustment component is not adjusted, and the plug rod assembly can be directly inserted into the initial locking component. At this time, there can be an angle bend at the connection of the two sets of power pipes, so that the initial leveling and alignment treatment is not required. After the initial locking is completed, the two sets of power pipes can be adjusted to make them tend to be horizontal. At this time, the adjustment component can be adjusted so that the plug rod assembly is adjusted to insert into the final locking component to complete the final locking. After the final locking is completed, the angle bend adjustment at the connection of the two sets of power pipes can no longer be performed.

[0030] A drainage assembly is installed inside the main pipe 1 at the corresponding position of the pipe pillow 2. The drainage assembly can drain the condensate in the main pipe 1 and at the same time prevent the permeate in the backfill soil from being transmitted into the main pipe 1.

[0031] The adjustment assembly includes an adjustment groove 6, which is located inside the base ring 5. The adjustment groove 6 is an annular groove. The base ring 5 has movable holes 7 spaced around its side near the main pipe 1. The movable holes 7 penetrate the side wall of the base ring 5 and communicate with each other inside the adjustment groove 6. An inner adjustment ring 9 is movably installed inside the adjustment groove 6 and can rotate inside the adjustment groove 6. An adjustment ring 8 is movably installed on the outside of the base ring 5. The adjustment ring 8 and the inner adjustment ring 9 are movably connected to each other. The adjustment ring 8 can drive the inner adjustment ring 9 to rotate inside the adjustment groove 6. An auxiliary adjustment groove 10 is spaced around the side wall of the inner adjustment ring 9 and penetrates the side wall of the inner adjustment ring 9. The auxiliary adjustment groove 10 gradually narrows from one end to the other. The insertion rod assembly is located inside the adjustment groove 6 and penetrates the auxiliary adjustment groove 10. By rotating the inner adjustment ring 9, the auxiliary adjustment groove 10 moves in the adjustment groove 6 and its inner diameter relative to the position of the insertion rod assembly gradually narrows, thereby driving the insertion rod assembly to move and adjust.

[0032] The base ring 5 has a sliding groove 24 spaced around its side wall. The sliding groove 24 passes through the side wall of the base ring 5 and communicates with the adjustment groove 6. A connecting rod 26 is fixedly installed around the inner wall of the adjustment ring 8. The connecting rod 26 is fixedly connected to the outer wall of the inner adjustment ring 9 through the sliding groove 24.

[0033] The insertion rod assembly includes an insertion rod 12, which is installed inside the adjusting groove 6. The position and number of insertion rods 12 correspond to the position and number of movable holes 7. One end of the insertion rod 12 extends through the movable hole 7 to the base ring 5 near the main pipe 1, and the other end of the insertion rod 12 slides through the adjusting ring 14 to the base ring 5 away from the main pipe 1. The insertion rod 12 is equipped with a final fastener main component, a primary fastener component, and a final fastener auxiliary component in the buckle plate 15. The final fastener main component, the primary fastener component, and the final fastener auxiliary component are installed sequentially at the end of the insertion rod 12 away from the main pipe 1. During the initial locking operation, the final fastener main component passes through the initial locking assembly but does not insert into the final locking assembly. At this time, the primary fastener component will insert into the initial locking assembly to complete the initial locking operation. During the final locking operation, the final fastener main component will insert into the final locking assembly. At this time, the primary fastener component will pass through the initial locking assembly, and at the same time, the final fastener auxiliary component will insert into the initial locking assembly to complete the final locking operation.

[0034] An adjustment cone 27 is installed on the plug rod 12 at the position corresponding to the auxiliary adjustment groove 10 on the inner adjustment ring 9. The adjustment cone 27 gradually narrows from the end away from the main pipe 1 to the end closer to the main pipe 1. A limit plate 28 is fixedly installed at the narrow end of the adjustment cone 27. A movable plate 29 is movably installed on the limit plate 28 at the wide end away from the adjustment cone 27. The movable plate 29 can move on the narrow end of the adjustment cone 27. A locking rod 31 is fixedly installed on the side wall of the movable plate 29 corresponding to one side of the inner adjustment ring 9. A moving groove 25 is opened on the side wall of the inner adjustment ring 9 corresponding to the position of the movable plate 29. The moving groove 25 is an arc-shaped groove. A locking hole 11 is opened on the inner side of the moving groove 25 corresponding to the narrow end of the auxiliary adjustment groove 10. The locking hole 11 penetrates the side wall of the inner adjustment ring 9. A spring element 30 is fixedly installed between the limit plate 28 and the locking rod 31. The spring element 30 enables the movable plate 29 to be elastically adjusted on the adjustment cone 27.

[0035] In the initial state, the wide end of the adjusting cone 27 on the plug rod 12 is located at the wide end of the auxiliary adjusting groove 10. Simultaneously, the locking rod 31 on the moving plate 29 is inserted into the moving groove 25 at the end away from the locking hole 11. When the adjusting ring 8 is rotated, the auxiliary adjusting groove 10 on the inner adjusting ring 9 rotates synchronously, gradually narrowing inside the auxiliary adjusting groove 10, causing the adjusting cone 27 to move accordingly. This, in turn, causes the plug rod 12 to move, allowing the final fastener, initial fastener, and... The final locking accessory moves toward the initial locking assembly and the final locking assembly. When the narrow end of the adjusting cone 27 moves to the narrow end position on the auxiliary adjusting groove 10, the locking rod 31 on the moving plate 29 will be inserted into the locking hole 11. During this process, the moving plate 29 is elastically adjusted and restricted by the elastic member 30, so that the moving plate 29 is adapted and adjusted at the narrow end on the adjusting cone 27 until the locking rod 31 on the moving plate 29 moves to the locking hole 11 position, and then the locking rod 31 will be inserted into the locking hole 11 through the elastic member 30.

[0036] A limiting block 13 is fixedly installed at one end of the plug rod 12 near the main pipe 1. The outer diameter of the limiting block 13 is adapted to the inner diameter of the movable hole 7. The outer diameter of the plug rod 12 is smaller than the inner diameter of the movable hole 7. The limiting block 13 is located at the end of the movable hole 7 away from the inner side of the adjusting groove 6. When the plug rod 12 moves, the limiting block 13 will move synchronously into the movable hole 7. In the initial locking state, the plug rod 12 does not move. At this time, the limiting block 13 will not move into the movable hole 7. One end of the plug rod 12 corresponding to the limiting block 13 can move within the movable hole 7. The other end of the plug rod 12 is restricted by the initial locking component and the final locking component on the plug tube 17, as well as the retaining ring plate 15, so that the retaining ring plate 15 and another set of power pipes can pass through the adjusting ring 1. 4. Angle adjustment is performed between the base ring 5 and the plug rod 12 (the end of the plug rod 12 corresponding to the base ring 5 can be adjusted). When the limiting block 13 is inserted into the movable hole 7, the end of the plug rod 12 corresponding to the base ring 5 cannot be adjusted within the movable hole 7. At this time, the buckle plate 15 and the other set of power pipes can no longer be angled between the base ring 5 and the adjusting ring 14 (because the end of the plug rod 12 corresponding to the base ring 5 cannot be adjusted). During this process, when the plug rod 12 cannot drive the limiting block 13 to move into the movable hole 7, it indicates that there is a large angle deviation between the buckle plate 15 and the other set of power pipes and the base ring 5, and it needs to be adjusted. When the adjustment is such that the limiting block 13 can be inserted into the movable hole 7, the horizontal adjustment between the two sets of power pipes is completed.

[0037] The inner diameter of the movable hole 7 and the outer diameter of the plug rod 12 can be adjusted according to the required bending angle at the connection between the two sets of power pipes.

[0038] A limiting ring 16 is fixedly installed on the inner side of the retaining ring plate 15 near the adjusting ring 14. The limiting ring 16 is an annular block, and the inner side of the limiting ring 16 is provided with movable grooves 18 at intervals. The position of the movable grooves 18 corresponds to the position of the plug rod 12. A retaining ring 19 is fixedly installed on the outer wall of the plug rod 12 corresponding to the inner side of the movable groove 18. The size of the retaining ring 19 is adapted to the inner diameter of the movable groove 18. Through the movable grooves 18 on the limiting ring 16 and the retaining ring 19 on the plug rod 12, the plug rod 12 and the retaining ring plate 15 can be kept synchronized. That is, the end of the plug rod 12 corresponding to the retaining ring plate 15 will not move and adjust within the retaining ring plate 15. The retaining ring plate 15 can drive the plug rod 12 to adjust synchronously.

[0039] By setting the plug rod 12 to be unable to move and adjust on the retaining plate 15, while the retaining plate 15 can drive the plug rod 12 to adjust its angle, the plugging operation can be completed without alignment adjustment. Simply adjust the retaining plate 15 so that it corresponds to the plug tube 17 on another set of power pipes.

[0040] The initial locking assembly includes a secondary locking ring 21, which is fixedly installed on the insertion tube 17. Secondary locking holes 22 are spaced around the secondary locking ring 21. Anti-return rings 40 are fixedly installed at intervals inside the secondary locking holes 22. The anti-return rings 40 are annular plates with an inclined triangular cross-section and are inclined towards the side closer to the final locking assembly.

[0041] A secondary insertion hole 41 is provided on the inner side of the secondary lock hole 22, corresponding to the two adjacent sets of return rings 40. A stop ring 23 is fixedly installed on the secondary lock ring 21 on the side away from the final locking component. The position of the stop ring 23 corresponds to the position of the secondary lock hole 22. The inner side of the stop ring 23 away from the secondary lock ring 21 is arc-shaped.

[0042] The initial fastener includes a retaining ring 34, which is an annular plate with an inclined triangular cross-section. The inclination direction of the retaining ring 34 is opposite to the inclination direction of the backstop ring 40.

[0043] When the initial fastener on the plug rod 12 is inserted into the secondary lock hole 22, the inclined surface of the retaining ring 34 will move into the secondary lock hole 22 until the retaining ring 34 is fully inserted into the secondary lock hole 22. At this time, the inclined angle on the retaining ring 34 will form a latch with the inclined angle of the return ring 40. At this time, the plug rod 12 is only allowed to move towards the side closer to the final locking assembly, and the plug rod 12 is not allowed to move in the opposite direction, thus completing the initial locking operation.

[0044] The final fastener includes an inner through groove 35, which is formed around the insertion rod 12. Auxiliary holes 38 are arranged in parallel around the side wall of the insertion rod 12. The auxiliary holes 38 penetrate the side wall of the insertion rod 12 and communicate with each other in the inner through groove 35. The distance between two adjacent sets of auxiliary holes 38 is the same as the distance between two adjacent sets of secondary insertion holes 41. Pressure blocks 36 are installed in the outer wall of the insertion rod 12 at intervals. The pressure blocks 36 are located on the side of the auxiliary holes 38 away from the initial fastener and are located in the inner through groove 35. A locking rod 39 is movably installed in the auxiliary holes 38. The inner through groove 35 is filled with internal pressure material 37.

[0045] After the fastener is removed from the initial locking assembly, the auxiliary hole 38 on the plug rod 12 will move into the secondary locking hole 22. When the pressure block 36 on the plug rod 12 moves to the corresponding position of the retaining ring 23, the pressure block 36 is pressed into the inner through groove 35, so that the inner pressure material 37 inside the inner through groove 35 is pressed and pushes the locking rod 39 out of the auxiliary hole 38, so that the locking rod 39 will be inserted into the secondary plug hole 41, thereby completing the final locking operation on the initial locking assembly.

[0046] The final locking assembly includes a primary locking ring 20, which is fixedly installed on the insertion tube 17 near the main tube 1. The primary locking ring 20 and secondary locking rings 21 are spaced apart. Primary locking holes 42 are spaced around the primary locking ring 20 near the secondary locking rings 21. An inner adjusting groove 43 is formed on the side wall of the insertion tube 17 corresponding to the primary locking hole 42. The inner diameter of the inner adjusting groove 43 is larger than the inner diameter of the primary locking hole 42, and the inner adjusting groove 43 and the primary locking hole 42 are interconnected. A rotating groove 47 is spaced around the inner side of the primary locking hole 42. A pressure transmitting groove 45 is formed on the inner side of the inner adjusting groove 43 corresponding to the rotating groove 47. The pressure transmitting groove 45 and the rotating groove 47 are interconnected. A pressure transmitting groove 45 is formed on the inner side of the inner adjusting groove 43 corresponding to the rotating groove 47. A pressure plate 44 is installed at the primary lock hole 42. The pressure plate 44 is fixedly installed in the inner adjustment groove 43 by a spring block. The size of the pressure plate 44 is adapted to the inner diameter of the primary lock hole 42. A push block 46 is movably installed on the inner side of the pressure transmission groove 45. The push block 46 can move within the pressure transmission groove 45. The pressure plate 44 and the inner side of the inner adjustment groove 43, and the push block 46 and the inner side of the pressure transmission groove 45 are all sealed. This sliding sealing technology is a disclosed technology and will not be described in detail here. A rotating plate 48 is movably installed at an inclination on the inner side of the rotating groove 47. The rotating plate 48 can be rotated and adjusted within the rotating groove 47. A primary insertion hole 49 is opened on the side wall of the rotating plate 48 away from the pressure transmission groove 45.

[0047] The final fastener includes a relief groove 32, which is formed around the side wall of the plug rod 12. A locking block 33 is fixedly installed in the relief groove 32 at the end away from the initial fastener. The size of the locking block 33 is adapted to the size of the primary plug hole 49.

[0048] When the plug rod 12 is inserted into the primary locking hole 42 and presses the pressure plate 44, the pressure plate 44 is pressed into the inward adjusting groove 43. The pushing block 46 is affected by the air pressure in the inward adjusting groove 43 and moves from the pressure transmission groove 45 into the rotation groove 47, which in turn pushes the rotating plate 48 to rotate until the rotating plate 48 rotates away from the end of the pressure transmission groove 45 and rotates into the relief groove 32 on the plug rod 12, until the primary plug hole 49 on the rotating plate 48 is locked onto the locking block 33. At this time, the final locking operation is completed.

[0049] It should be noted that the internal regulating tank 43 can also be filled with internal pressure material 37. By filling with internal pressure material 37, the situation where the air pressure changes significantly due to environmental changes can be compensated.

[0050] The drainage assembly includes a drainage channel 50, which is located at the bottom inner side of the main pipe 1 and penetrates the side walls of the main pipe 1 and the pipe rest 2. On both sides of the main pipe 1 corresponding to the drainage channel 50, inclined guide grooves 51 are provided to guide condensate from the main pipe 1 into the drainage channel 50. A control box 52 is fixedly installed on the inner side of the main pipe 1 above the drainage channel 50. A control groove 54 is provided inside the control box 52. Control shafts 55 are movably installed on both sides of the control groove 54, and are mounted within the control groove 54 via torsion spring components. A liquid-blocking plate 53 is wound around the control groove 54, with the end of the liquid-blocking plate 53 away from the control shaft 55 sliding through the bottom of the control box 52. The liquid blocking plate 53 is fixedly installed at the bottom of the inner side of the liquid guiding groove 51. Both sides of the liquid blocking plate 53 away from the liquid drainage channel 50 are equipped with stop strips 56. The stop strips 56 are fixedly installed between the liquid guiding groove 51 and the control box 52. Both sides of the liquid blocking plate 53 near the liquid drainage channel 50 are equipped with limit strips 57. The limit strips 57 are fixedly installed on the side wall of the control box 52, and there is a gap between the bottom end of the limit strips 57 and the bottom wall of the liquid guiding groove 51. Limit rods 58 are fixedly installed at intervals between two adjacent sets of limit strips 57. The liquid blocking plate 53 protrudes towards the side near the liquid drainage channel 50. The stop strips 56 and the limit strips 57 are both arc-shaped strips adapted to the curvature of the liquid blocking plate 53. The top two sides of the liquid drainage channel 50 are inclined with drainage grooves 59.

[0051] When condensate accumulates in the liquid guiding groove 51, the condensate will put pressure on the bottom of the liquid blocking plate 53, causing the concave surface of the liquid blocking plate 53 to deform under pressure. The deformed liquid blocking plate 53 will be adjusted through the gap between the limiting strip 57 and the liquid guiding groove 51, so that it bulges into the drain channel 50 and moves towards the side of the diversion groove 59, thereby connecting the concave area of ​​the liquid blocking plate 53 with the inside of the diversion groove 59, so that the condensate flows into the drain channel 50 through the diversion groove 59 to complete the draining operation. At the same time, the liquid blocking plate 53 is restricted by the stop strip 56 and cannot be adjusted to bulge into the concave surface, so that the liquid in the drain channel 50 cannot permeate back into the liquid guiding groove 51.

[0052] To further explain, only one end of the pipe support 2 is equipped with a drainage component. The drainage component on the pipe support 2 faces the ground, enabling it to perform drainage operations stably. Only one drainage component needs to be installed on the pipe support 2 to meet the operational requirements, and no additional components are required.

[0053] The working principle of this invention is: When using the power pipe of the present invention, the plug 4 of one pipe is roughly inserted into the snap-fit ​​connector 3 of another pipe. The initial fastener at the front end of the plug rod 12 is inserted into the secondary lock hole 22 of the initial locking assembly, which cooperates with the inclined surface of the anti-return ring 40 to form a one-way lock to prevent it from coming out. At this time, since the limiting block 13 at the tail of the plug rod 12 does not enter the movable hole 7, the connection can be bent at a small angle by the adjusting ring 14, thereby completing the initial locking operation. After the initial locking operation is completed, the two pipes are manually adjusted to be horizontal. Then, the adjusting ring 8 is rotated, and the adjusting cone 27 is pushed through the auxiliary adjusting groove 10 on the inner adjusting ring 9, so that the plug rod 12 moves synchronously and smoothly into the plug joint 4. The movement of the plug rod 12 triggers two parallel actions: The final fastener on the plug rod 12 enters the final lock assembly. The plug rod 12 presses against the pressure plate 44, and the internal pressure drives the push block 46 to move and push the rotating plate 48, causing the rotating plate 48 to rotate into the clearance groove 32, so that the first-stage insertion hole 49 is locked onto the locking block 33. At the same time, the initial fastener is disengaged from the initial lock assembly, and the final fastener auxiliary component moves into the initial lock assembly. The pressure block 36 is pressed, which drives the internal pressure material 37 in the inner through groove 35 to conduct and adjust, so that the locking rod 39 extends under internal pressure and is locked into the second-stage insertion hole 41, completing the auxiliary locking in the initial lock position. When the plug rod 12 moves, the limiting block 13 at its tail enters the movable hole 7, eliminating the radial movement gap and making it impossible for the plug rod 12 to complete the movement adjustment. The condensate generated in the pipeline gathers in the liquid guiding tank 51, presses the liquid blocking plate 53 and adjusts its displacement, opens the passage, and flows into the drainage channel 50 through the diversion tank 59 for discharge.

[0054] The above description is only a preferred embodiment 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.
