Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of power construction, in particular to an SMC composite round cable trench. BACKGROUND

[0002] In many fields such as power engineering and communication engineering, the safe laying and protection of cables are of great importance, and the performance of the cable trench as a bearing and protection device for cables directly affects the quality and stability of the entire project.

[0003] At present, there are many problems in the actual application of cable trenches on the market. Among them, the misalignment of the cable trench during butt joint is particularly prominent. The connection mode of the traditional cable trench is relatively simple, mostly using simple buckle connection or bolt connection. In the actual installation process, due to the complex construction environment, it is difficult for the operator to accurately butt joint the cable trenches. Once the butt joint is misaligned, not only will it cause the gap between the cable trenches to be too large, affecting the protection effect of the cable, but also it may hinder the laying of the cable, increasing the construction difficulty and cost. CONTENT OF THE INVENTION

[0004] To overcome the above defects, embodiments of the present disclosure provide an SMC composite round cable trench, which solves the problem of misalignment and difficulty in butt joint of the cable trench in the prior art.

[0005] According to one aspect, at least one embodiment of the present disclosure provides an SMC composite round cable trench for receiving cables after being spliced with each other, comprising:

[0006] a slot pipe;

[0007] a plug-in section and a cladding section, the plug-in section and the cladding section are respectively arranged at both ends of the slot pipe;

[0008] After the adjacent slot pipes are close to each other, the plug-in section is located in the adjacent slot pipe and abuts against the inner wall of the adjacent slot pipe, and the cladding section is located outside the adjacent slot pipe and abuts against the outer wall of the adjacent slot pipe.

[0009] For example, in the SMC composite round cable trench provided by at least one embodiment of the present disclosure, the slot pipe is divided into an upper protective pipe and a lower protective pipe, and the upper protective pipe has limiting protrusions on both sides;

[0010] After the upper protective pipe is close to the lower protective pipe, the limiting protrusions contact the two sides of the lower protective pipe, so as to limit the position of the upper protective pipe and the lower protective pipe.

[0011] For example, the SMC composite round cable duct provided by at least one embodiment of the present disclosure comprises a plug-in section at one end of the lower protective pipe and a cladding section at one end of the upper protective pipe.

[0012] For example, the SMC composite round cable duct provided by at least one embodiment of the present disclosure comprises a rolling-preventing surface on the duct pipe.

[0013] For example, the SMC composite round cable duct provided by at least one embodiment of the present disclosure comprises a clamping protrusion at one end of the lower protective pipe away from the plug-in section, and a clamping hole at one end of the lower protective pipe close to the plug-in section.

[0014] After the adjacent lower protective pipes are close to each other, the clamping protrusion enters the clamping hole.

[0015] For example, the SMC composite round cable duct provided by at least one embodiment of the present disclosure comprises a rounded corner on the clamping protrusion.

[0016] For example, the SMC composite round cable duct provided by at least one embodiment of the present disclosure comprises a chamfer at both ends of the lower protective pipe and the upper protective pipe.

[0017] For example, the SMC composite round cable duct provided by at least one embodiment of the present disclosure comprises a first locking part on both sides of the upper protective pipe and a second locking part on the lower side of the lower protective pipe; after the upper protective pipe is close to the lower protective pipe, the first locking part and the second locking part abut, and the SMC composite round cable duct further comprises:

[0018] A fastener for limiting the position of the first locking part and the second locking part.

[0019] For example, the SMC composite round cable duct provided by at least one embodiment of the present disclosure comprises a plurality of fasteners, and one end of each fastener comprises a clamping part.

[0020] Each of the plurality of fasteners is rotatably arranged on the first locking part and the second locking part.

[0021] After the plurality of fasteners are rotated, the plurality of clamping parts are clamped with the first locking part and the second locking part respectively, so as to limit the position of the first locking part and the second locking part.

[0022] For example, the SMC composite round cable duct provided by at least one embodiment of the present disclosure comprises a rolling-preventing surface on one side of the lower protective pipe.

[0023] The embodiments of the present disclosure have the following beneficial effects:

[0024] In the present disclosure, when installing the cable trough, the splicing section of one trough pipe is aligned with the port of the adjacent trough pipe, and is slowly inserted so that the splicing section closely fits the inner wall of the adjacent trough pipe. At the same time, the wrapping section is wrapped around the outer wall of the adjacent trough pipe to ensure that it closely abuts the outer wall. Repeat this step to complete the splicing of multiple trough pipes and form a continuous cable storage channel.

[0025] The advantage is that the unique design of the splicing section and the wrapping section makes the splicing of adjacent trough pipes more stable. The splicing section goes deep into the interior to provide internal support and positioning, and the wrapping section wraps around the outside to enhance the sealing and stability of the connection. Effectively solves the problems of existing cable trough butt deviation and difficulty in butt joint, improves the installation efficiency and splicing quality. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION ​​​​

[0034] The present disclosure will be further described in details with reference to the drawings and examples. It can be understood that the specific examples described herein are merely used to explain the present disclosure, but not to limit the present disclosure.

[0035] For the simplicity of the drawings, only the parts related to the disclosure are shown in each drawing, which does not represent the actual structure of the product. In addition, for the simplicity of the drawings and easy understanding, in some drawings, only one of the parts with the same structure or function is shown, or only one of them is marked. In this document, "one" not only means "only one", but also means "more than one" situation, and "several" includes "two" and "more than two".

[0036] In this document, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0037] In the present disclosure, unless otherwise specified and limited, "on" or "under" the first feature of the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, "on", "above" and "above" of the first feature of the second feature includes that the first feature is directly above and obliquely above the second feature, or only means that the horizontal height of the first feature is higher than that of the second feature. The "below", "below" and "below" of the first feature of the second feature includes that the first feature is directly below and obliquely below the second feature, or only means that the horizontal height of the first feature is less than that of the second feature.

[0039] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0040] As Figures 1-6As shown in the figure, it shows an SMC composite material circular cable trough in an embodiment of the present disclosure, used to accommodate cables after mutual splicing, including a trough pipe 1; a plug-in section 2 and a cladding section 3 are respectively arranged at both ends of the trough pipe 1; adjacent trough pipes 1 are close to each other, the plug-in section 2 is located in the adjacent trough pipe 1 and abuts against the inner wall of the adjacent trough pipe 1; the cladding section 3 is located outside the adjacent trough pipe 1 and abuts against the outer wall of the adjacent trough pipe 1.

[0041] For example, as shown in the figure, in order to solve the problem that the cable trough is prone to deviation and is not easy to butt joint in the prior art, an SMC composite material circular cable trough is designed. When installing the cable trough, the plug-in section 2 of one trough pipe 1 is aligned with the port of the adjacent trough pipe 1, and is slowly inserted so that the plug-in section 2 is tightly attached to the inner wall of the adjacent trough pipe 1. At the same time, the cladding section 3 is wrapped around the outer wall of the adjacent trough pipe 1 to ensure that it is tightly abutted against the outer wall. Repeat the steps to splice multiple trough pipes 1 to form a continuous cable accommodation channel. Figure 1

[0042] The advantage is that the unique design of the plug-in section 2 and the cladding section 3 makes the splicing of adjacent trough pipes 1 more stable. The plug-in section 2 extends into the interior to provide internal support and positioning; the cladding section 3 wraps around the exterior to enhance the sealing and stability of the connection. This effectively solves the problems of deviation and difficulty in butt joint of existing cable troughs, improving installation efficiency and splicing quality.

[0043] In some examples, the trough pipe 1 is divided into an upper protective pipe 11 and a lower protective pipe 12, and the upper protective pipe 11 has limiting protrusions 111 on both sides. When the upper protective pipe 11 is close to the lower protective pipe 12, the limiting protrusions 111 on both sides of the upper protective pipe 11 come into contact with the lower protective pipe 12 to limit the position of the upper protective pipe 11 and the lower protective pipe 12.

[0044] For example, as shown in the figure, when installing the upper protective pipe 11 and the lower protective pipe 12, align the limiting protrusions 111 on both sides of the upper protective pipe 11 with the lower protective pipe 12, and place the upper protective pipe 11 so that the limiting protrusions 111 come into contact with the lower protective pipe 12 to position the upper protective pipe 11 and the lower protective pipe 12. Figure 2

[0045] The advantage is that the limiting protrusions 111 can quickly and accurately position the upper protective pipe 11 and the lower protective pipe 12 during installation, avoiding mispositioning, improving installation accuracy, enhancing the stability of the overall structure of the trough pipe 1, and ensuring the protection effect on the cable.

[0046] In some examples, the plug-in section 2 is located at one end of the lower protective pipe 12, and the cladding section 3 is located at one end of the upper protective pipe 11.

[0047] For example, as shown in the figure, when installing the upper protective pipe 11 and the lower protective pipe 12, align the limiting protrusions 111 on both sides of the upper protective pipe 11 with the lower protective pipe 12, and place the upper protective pipe 11 so that the limiting protrusions 111 come into contact with the lower protective pipe 12 to position the upper protective pipe 11 and the lower protective pipe 12. Figures 1-2 ​​As shown, when splicing cable troughs, first connect the end of the lower protective tube 12 with the plug section 2 to the adjacent trough tube 1. After that, cover the splice with the end of the upper protective tube 11 with the covering section 3, so that the two fit together tightly and the splicing of the entire cable trough is achieved.

[0048] The advantage is that this layout allows the upper sheath 11 and the lower sheath 12 to have a clear division of labor during the splicing process. The plug section 2 of the lower sheath 12 is responsible for the initial positioning and connection, while the covering section 3 of the upper sheath 11 further reinforces and seals, improving the stability and reliability of the splicing and ensuring the overall performance of the cable trough.

[0049] In some examples, the groove 1 has an anti-roll surface 121.

[0050] For example, such as Figure 3 As shown, at the cable laying site, if the cable trough is placed on an inclined or uneven ground, the cable trough with anti-roll surface 121 can be placed stably and will not roll easily, which facilitates the subsequent cable laying and installation work.

[0051] The advantage is that the anti-roll surface 121 design effectively solves the problem of circular cable troughs easily rolling when placed, enhances the stability of the cable troughs in various environments, provides convenience for construction, and reduces unexpected situations during construction.

[0052] In some examples, the lower protective tube 12 has a snap-fit ​​protrusion 122 at the end away from the insertion section 2; the lower protective tube 12 has a snap-fit ​​hole 123 at the end near the insertion section 2; when adjacent lower protective tubes 12 come close to each other, the snap-fit ​​protrusion 122 enters the snap-fit ​​hole 123.

[0053] For example, such as Figure 2 As shown, when splicing adjacent lower protective tubes 12, align the snap-fit ​​protrusion 122 of one lower protective tube 12 with the snap-fit ​​hole 123 of another lower protective tube 12, and gently push it in so that the snap-fit ​​protrusion 122 is fully inserted into the snap-fit ​​hole 123, thus completing the initial fixation of the adjacent lower protective tubes 12.

[0054] The advantage is that the cooperation between the snap-fit ​​protrusion 122 and the snap-fit ​​hole 123 provides an additional connection method for adjacent lower protective tubes 12, enhances the connection strength between the lower protective tubes 12, further ensures the overall stability of the cable trough after splicing, and reduces problems caused by loose connections.

[0055] In some examples, the snap-fit ​​protrusion 122 has rounded corners.

[0056] For example, such as Figure 4 As shown, when the snap-fit ​​protrusion 122 aligns with the snap-fit ​​hole 123, the rounded corner design makes the snap-fit ​​process smoother. Precise alignment is not required; a gentle push is all it takes to complete the snap-fit, thus improving splicing efficiency.

[0057] The rounded design of the clamping protrusions 122 reduces the difficulty of clamping, making the installation process more convenient, and avoids installation damage caused by sharp corners, prolonging the service life of the cable trough.

[0058] In some examples, the lower protection pipe 12 and the upper protection pipe 11 are both chamfered at both ends.

[0059] For example, as shown in FIG. 1, when the upper protection pipe 11 and the lower protection pipe 12 are transported and installed, the chamfering can effectively prevent personnel from being cut by sharp corners, and the chamfering can also guide better docking during splicing. Figure 4

[0060] The chamfering design at both ends of the upper protection pipe 11 and the lower protection pipe 12 not only ensures the safety of construction personnel, but also optimizes the splicing process, improving the safety and convenience of pipe docking.

[0061] In some examples, the upper protection pipe 11 has a first locking portion 112 on both sides, and the lower protection pipe 12 has a second locking portion 124 on the lower side; after the upper protection pipe 11 is close to the lower protection pipe 12, the first locking portion 112 and the second locking portion 124 abut, and further comprising a fastener 4, the fastener 4 is used to limit the position of the first locking portion 112 and the second locking portion 124.

[0062] For example, as shown in FIG. 1, after the upper protection pipe 11 and the lower protection pipe 12 are installed, the first locking portion 112 and the second locking portion 124 are tightly abutted, and then the fastener 4 is used to fix them, ensuring that the upper protection pipe 11 and the lower protection pipe 12 are tightly combined. Figure 5 The cooperation of the first locking portion 112, the second locking portion 124 and the fastener 4 provides a reliable fixing method for the upper protection pipe 11 and the lower protection pipe 12, enhances the stability of the overall structure of the trough pipe 1, and ensures the safety of the cable in the trough pipe 1.

[0063] In some examples, the fastener 4 has a clamping portion 41 at one end; the plurality of fasteners 4 are respectively rotationally arranged on the first locking portion 112 and the second locking portion 124; after the plurality of fasteners 4 are rotated, the plurality of clamping portions 41 are respectively clamped with the first locking portion 112 and the second locking portion 124, for limiting the position of the first locking portion 112 and the second locking portion 124.

[0064] For example, as shown in FIG. 1, the fastener 4 with the clamping portion 41 is respectively rotationally installed on the first locking portion 112 and the second locking portion 124, and the fastener 4 is rotated to make the clamping portion 41 clamped with the corresponding locking portion, realizing the tight fixing of the two, preventing loosening.

[0065] Figure 5

[0066] ​​​The advantage is that this rotating snap fastener 4 design is simple and convenient to operate, can quickly fix the first locking part 112 and the second locking part 124, and the fixing effect is firm, improving installation efficiency and ensuring the stable use of the cable tray.

[0067] In some examples, the anti-roll surface 121 is located on one side of the lower guard tube 12.

[0068] For example, such as Figure 3 As shown, when placing the cable trough, the lower protective pipe 12 with the anti-roll surface 121 is in contact with the ground. No matter what the ground condition is, the cable trough can remain stable and will not roll randomly, which facilitates subsequent construction operations.

[0069] The advantage is that the anti-roll surface 121 is located on the lower protective tube 12 and is in direct contact with the placement surface, which effectively enhances the stability of the cable trough placement, avoids positional displacement caused by rolling, and provides a stable foundation for cable laying and installation.

[0070] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
