Abstract
Description
Technical Field
[0001] This utility model relates to the field of power pipe technology, specifically a power pipe that is easy to connect. Background Technology
[0002] Power conduits are crucial components in power systems used to protect and transmit power cables. In existing projects, power conduit splicing commonly uses hot-melt welding, but this method has too many limitations. Insufficient melting or abnormal cooling can directly lead to structural defects at the joint.
[0003] In existing technologies, mechanical splicing methods have been introduced to replace the hot-melt method for connecting pipes. However, when the underground soil is squeezed or construction vibration occurs, the two pipes are simply clamped together without positioning, which may lead to problems such as breakage at the connection and eccentric displacement. For example, application number: CN202221166602.0, describes an MPP power pipe that is easy to connect, which is positioned by a combination of guide grooves and guide posts with a snap-fit method. However, the device has the following drawback: there is no radial constraint in the circumferential direction. If external force is applied, the clamping point is prone to failure, resulting in the exposure of the internal components of the power pipe that need to be protected. Utility Model Content

[0005] To achieve these objectives and other advantages according to the present invention, an easy-to-connect power conduit is provided, comprising: a conduit body, and further comprising:
[0006] The front of the tube body is provided with a circumferentially distributed set of locking blocks, and the back of the tube body is provided with a circumferentially distributed set of locking grooves that are adapted to the locking block set. The lower half of the outer wall at both ends of the tube body is symmetrically provided with three sets of circumferentially distributed sliders.

[0009] Preferably, the structure of the limiting connection component includes:
[0010] The lower half ring sleeve has the aforementioned groove, the port of the groove is located at the right end, and the length of the groove is less than the length of the lower half ring sleeve.

[0020] This device connects to the outside of the pipe body through a limiting connection component, restricting the axial displacement of the pipe body and resisting the tension or soil compression during pipe laying. It also prevents loosening at the connection point. In addition, the embedded installation method of the locking block group and the locking groove restricts the circumferential rotation of the pipe body at the joint and prevents the pipe body from being misaligned when the cable is laid. The connection can be achieved without the need for traditional heat fusion connection method. The structure is simple and the operation is convenient.

[0033] The present invention will now be described in detail with reference to the accompanying drawings:
[0034] Figure 1-5 This invention discloses a power conduit for easy connection, comprising: a conduit body 1, and further comprising:
[0035] The front of the tube body 1 is provided with a circumferentially distributed locking block group 2, and the back of the tube body 1 is provided with a circumferentially distributed locking groove group 3 that matches the locking block group 2. The lower half of the outer wall at both ends of the tube body 1 is symmetrically provided with three circumferentially distributed slider groups 4.
[0036] The limiting connection component 5 has three sets of sliding grooves 6 arranged in a circular pattern on its lower inner wall to match the slider group 4.
[0037] The fixing component 70 is disposed on the limiting connection component 5, and the limiting connection component 5 is fixed to the tube body 1 through the fixing component 70.
[0038] Working principle:
[0039] When two power pipes need to be connected, align the locking groove group 3 on the back of the front section 1 with the locking block group 2 on the front of the rear section 1, and then insert the locking block group 2 into the corresponding locking groove to complete the initial connection of the front and rear power pipes.
[0040] The operator then fits the limiting connection component 5 against the outer wall of the previous section of pipe 1, pushes the limiting connection component 5 until it reaches the slide groove 6, and slides the slider group 4 of the previous section of pipe 1 and the slider group 4 of the next section of pipe 1 into the slide groove 6 from left to right until the limiting connection component 5 completely covers the connection between the two sections of pipe 1 (the slider group 4 is completely placed in the slide groove 6), thus completing the connection of the power pipe. Finally, the limiting connection component 5 is fixed to the pipe 1 by the fixing component 70 to complete the installation.
[0041] Among them, ① there are several locking block groups 2 and locking groove groups 3 (three groups are optimal in actual use), and several slider groups 4 are distributed in a circular pattern. The purpose of setting several is to avoid the overall splicing being affected even if one of them is worn after long-term use.
[0042] ② In actual use, if this device is applied to an underground application, to prevent moisture or silt in the soil from entering the pipe through the joint gap of the pipe body 1, which could cause the cable to become damp or blocked, waterproof sealant can be applied to the inside of the locking groove assembly 3, or a waterproof sealing ring can be installed on the mating surface between the ring and the pipe body 1 to improve the sealing performance.
[0043] In summary, this device connects to the outside of the pipe body 1 via the limiting connection component 5, restricting the axial displacement of the pipe body 1 and resisting the tension or soil compression during pipe laying. It also prevents loosening at the connection point. In addition, the insertion installation method of the locking block group 2 and the locking group groove restricts the circumferential rotation of the pipe body 1 at the docking point, preventing the pipe body 1 from being misaligned when the cable is laid. The device can achieve docking without the need for traditional heat fusion connection, and has a simple structure and is easy to operate.
[0044] As described above, the structure of the limiting connection component 5 includes:
[0045] The lower half ring 51 has the groove 6 provided on it. The port of the groove 6 is located at the right end, and the length of the groove 6 is less than the length of the lower half ring 51. One end of the lower half ring 51 is provided with a connecting block I 52 with two sets of threaded holes.
[0046] The upper half ring 53 is hinged to one end of the lower half ring 51, and the other end is provided with a connecting block II 54 with two sets of through holes at the position opposite to the connecting block I 52.
[0047] The lower half-ring 51 and the upper half-ring 53 are bolted together by bolts through connecting block I 52 and connecting block II 54.
[0048] Working principle:
[0049] Before installation, the operator first flips the upper half ring 53 upward to expose the slide groove 6 of the lower half ring 51, then aligns the slide groove 6 of the lower half ring 51 with the slider group 4 of the lower half of the tube body 1, and pushes it along the axis of the tube body 1 so that the slider groups 4 of the front and rear sections of the tube body 1 slide into the slide groove 6 from the right end port of the slide groove 6 in sequence.
[0050] After the slider assembly 4 is fully inserted into the groove 6, the upper half of the ring 53 is flipped downwards so that it fits against the outer wall of the tube body 1. At this time, the connecting block II 54 of the upper half of the ring 53 is aligned with the connecting block I 52 of the lower half of the ring 51. The bolt is then passed through the through hole of the connecting block II 54 and screwed into the threaded hole of the connecting block I 52 and tightened. (In actual use, the bolt is further fixed by passing through the lower half of the connecting block I 52 with a nut, see details). Figure 4 This allows the upper half-ring 53 and the lower half-ring 51 to be tightly locked together. At this time, the limiting connection component 5 will completely wrap around the tube body 1, achieving further fixation and protection of the docking point.
[0051] If you need to disassemble tube 1, first unscrew the bolts, open the upper half of the ring 53, and then pull the ring out horizontally.
[0052] Since the length of the slide groove 6 is less than the length of the lower half ring 51, the slider group 4 will be blocked by the inner side of the slide groove 6 after it is fully inserted into the slide groove 6, and will not be able to continue sliding. This is to prevent the operator from moving too much and causing the limit connection component 5 to slide out of the splicing position.
[0053] As described above, the structure of the fixing component 70 includes:
[0054] The lower half ring 51 is symmetrically provided with transverse C-shaped sliders 7 on both sides. Multiple through holes 71 are opened through the outer side of the C-shaped slider 7, and multiple screw holes I 72 are opened through the inner side of the C-shaped slider 7 relative to the position of the through holes 71.
[0055] Two sets of ear flaps 73 are symmetrically arranged on the outer side of the tube body 1. The ear flaps 73 are laterally provided with slots 74 for C-shaped sliders 7 to slide, and multiple screw holes II 75 are provided on the outer side of the ear flaps 73.
[0056] The C-shaped slider 7 is bolted to the ear flap 73 by passing bolts through through hole 71, screw hole II 75 and screw hole I 72.
[0057] Working principle:
[0058] When the limiting connection component 5 slides against the outer wall of the tube body 1, the openings of the C-shaped sliders 7 on both sides will be inserted into the slots 74 of the ear flap 73 until the slider group 4 of the previous section of the tube body 1 is blocked by the inner wall of the slide groove 6 of the limiting connection component 5 and cannot move.
[0059] At this point, the operator passes the bolts through the through hole 71 on the outside of the C-shaped slider 7, the screw hole II 75 on the outside of the ear 73, and the screw hole I 72 on the inside of the C-shaped slider 7 in sequence, and then tightens the bolts so that the inner wall of the C-shaped slider 7 fits tightly against the outer wall of the ear 73. The above steps are repeated to connect the ear 73 on the other side to the C-shaped slider 7 with bolts, thus completing the overall installation of the limiting connection assembly 5 and the tube body 1.
[0060] In actual use, due to the U-shaped wrapping structure of the C-shaped slider 7, and the engagement of the groove 74 of the ear 73 with the edge of the C-shaped slider 7, even if the bolts are slightly loose, the C-shaped slider 7 can still maintain its connection with the ear 73 through the engagement of the groove 74. Moreover, with the provision of multiple screw holes I 72 and screw holes II 75, even if one of them wears off due to long-term use, it will affect the connection stability of the overall structure.
[0061] As described above, the inner wall of the upper ring 53 is provided with several irregular small grooves 8, and the upper outer walls of both ends of the tube 1 are symmetrically provided with several irregular small protrusions 81, and the irregular small grooves 8 and the irregular small protrusions 81 are matched.
[0062] Working principle:
[0063] When the upper half-ring 53 is flipped to approach the tube body 1, the irregular small grooves 8 (such as dot-shaped, strip-shaped, or serrated) on the inner wall of the upper half-ring 53 will first contact the irregular small protrusions 81 (in actual use, soft rubber material, such as silicone, can be selected) on the outer wall of the upper half of the tube body 1. Due to the concave-convex structure, the friction between the inner surface of the upper half-ring 53 and the outer wall of the tube body 1 can be increased, thus limiting the displacement of the upper half-ring 53.
[0064] In the above scheme, a sealing ring 9 that fits the inner wall of the tube body 1 is also provided on the front side.
[0065] Working principle:
[0066] When the two sections of the power pipe are connected, the sealing ring 9 on the front of the latter section of the pipe body 1 will be inserted into the inner pipe of the former section as it is spliced with the former section. Because the sealing ring 9 is compatible with the inner wall of the pipe body 1, the outer wall of the sealing ring 9 will fit tightly with the inner wall, initially preventing moisture and mud from seeping into the pipe from the joint gap.
[0067] In practical use, the sealing ring 9 should preferably be made of a material that can be integrally molded with the tube body 1, such as PVC and EPDM, to avoid the risk of detachment.
[0068] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
