Description

Technical Field

[0001] The utility model belongs to the technical field of cable laying, and more specifically relates to a cable trench unit and an assembled cable trench. Background Art

[0002] Cable trenches are underground pipes used to lay and replace power or telecommunication cable facilities. They are also the enclosure structures of the laid cable facilities. They have rectangular, circular, arched and other pipe structures. Traditional cable trench construction mostly uses steel formwork, wooden formwork and steel pipe support combination for installation, and uses brick or cast-in-place concrete cable trenches. This has the problems of large labor demand, long cycle, large amount of turnover materials, and complex process. Moreover, after the construction is completed, the vertical construction joints between the cable trench and the ground will have uneven settlement, which can easily cause uneven ground and affect the overall visual quality of the room.

[0003] In addition, due to the different areas of construction, the length of the cable trench is also different. Therefore, the general cable trench is formed by multiple groove units spliced ​​together, and the two adjacent groove units are fixed by screwing or clamping. However, this method not only requires drilling holes on the groove units, which increases the construction process and makes the groove units easily damaged during the drilling process, but also leads to low assembly efficiency. The gap between the two adjacent groove units also causes the connection to be not tight enough, and the connection failure problem is prone to occur after long-term use. Utility Model Content

[0028] Please also read Figures 1 to 3 The cable trench unit and assembled cable trench provided by the utility model are now described. The cable trench unit includes a main structure 1 and a sealing cover plate 2. The main structure 1 is provided with a receiving channel 101 for receiving cables along a first path. The top of the receiving channel 101 is connected to the outside. The main structure 1 is also provided with a mounting groove 103. The mounting groove 103 is located at one end of the main structure 1 along the first path. The main structure 1 has a mounting block 102 at the other end of the mounting groove 103. The mounting block 102 is plugged or snapped into the mounting groove 103 of the adjacent main structure 1. The sealing cover plate 2 is covered on the top of the main structure 1. The sealing cover plate 2 is detachably connected to the main structure 1 and is used to cover the top of the receiving channel 101.

[0029] Compared with the prior art, the cable trench unit provided by the utility model has a mounting block 102 and a mounting groove 103 at opposite ends thereof, respectively. The mounting block 102 is plugged or snapped into the mounting groove 103 of the adjacent main structure 1, thereby connecting the two adjacent main structures 1 to each other. After the cable is laid in the accommodating channel 101, the sealing cover plate 2 is then covered on the top of the main structure 1 to separate the top of the accommodating channel 101 from the outside. The utility model does not require the use of external connecting components, nor does it require drilling holes on the main structure 1. Multiple main structures 1 are connected in sequence by plugging or snapping to form a cable trench, which not only simplifies the connection structure and installation steps and improves the installation efficiency, but also avoids the problem of connection failure caused by loosening of the connecting components after long-term use, thereby improving the firmness of the connection between the two adjacent main structures 1.

[0030] Optionally, the mounting block 102 includes a connecting column connected to the main structure 1 and a conical block connected to the free end of the connecting column, the large diameter end of the conical block is connected to the connecting column, and the outer diameter of the conical block protrudes from the outer diameter of the connecting column, and the mounting groove 103 includes a first groove body adapted to the conical block and a second groove body adapted to the connecting column. The conical block is inserted into the first groove body along the second groove body and is clamped to the first groove body.

[0031] Specifically, the conical clamping block is an elastic plastic component, and the mounting block 102 is inserted into the mounting groove 103 along the first path.

[0032] In some embodiments, see Figure 4 The mounting block 102 includes a connecting area 1022 and a locking area 1021 connected to the connecting area 1022 on a side away from the main structure 1. The connecting area 1022 is connected to the main structure 1. The width of the locking area 1021 in the second path is greater than that of the connecting area 1022. The second path is perpendicular to the first path. The mounting block 102 is inserted into the adjacent mounting groove 103 along the up and down direction.

[0033] In this embodiment, the mounting block 102 is inserted from top to bottom into the mounting groove 103 of the adjacent main structure 1. Since the width of the locking area 1021 in the second path is greater than the connection area 1022, the locking area 1021 can be locked in the mounting groove 103, and the two adjacent main structures 1 are limited in the first path. The manufacturing process of this solution is simple, and the two adjacent main structures 1 are connected by plugging, which improves the installation efficiency. After the connection, the two adjacent main structures 1 are abutted, the connection gap is reduced, and the tightness of the connection is ensured.

[0034] Optionally, the cross-sections of the connecting area 1022 and the locking area 1021 are T-shaped structures.

[0035] In some embodiments, see Figure 1 and Figure 3The mounting block 102 is a wedge-shaped structure, and the size of the mounting block 102 in the second path gradually increases in the direction away from the main structure 1. The second path is perpendicular to the first path. The mounting groove 103 is adapted to the mounting block 102 and is plugged into and matched with the mounting block 102 in the up and down directions.

[0036] In this embodiment, a wedge-shaped mounting block 102 is inserted into the mounting groove 103, and the mounting block 102 is inserted into the mounting groove 103 of the adjacent main structure 1 from top to bottom, so that the two adjacent main structures 1 are limited in the first path to achieve a detachable connection. This solution not only increases the contact area between the mounting block 102 and the mounting groove 103, improves the fastness of the connection, but also the overall strength of the mounting block 102 is uniform and not easy to break.

[0037] In some embodiments, see Figure 2 A fixing groove 106 is opened on the top of the main structure 1, and the sealing cover plate 2 is inserted into the fixing groove 106.

[0038] The sealing cover plate 2 is inserted into the fixing groove 106, which increases the contact area between the sealing cover plate 2 and the main structure 1 and improves the sealing effect. In addition, since the fixing groove 106 is provided, after the sealing cover plate 2 is inserted into the fixing groove 106, the sealing cover plate 2 is flush with the top surface of the main structure 1, which prevents the sealing cover plate 2 from protruding from the main structure 1 and reduces the occupied space.

[0039] Optionally, the longitudinal cross-section of the fixing groove 106 is “L”-shaped, and the sealing cover plate 2 is inserted into the fixing groove 106 from top to bottom and abuts against the fixing groove 106 in the up-down direction.

[0040] In some embodiments, not shown in the figures, the fixing groove 106 is connected to the accommodating channel 101 along the second path and is isolated from the outside in the up and down directions, and the sealing cover plate 2 is inserted into the fixing groove 106 along the first path.

[0041] The sealing cover plate 2 is inserted into the fixing groove 106 along the first path, and the top and bottom of the fixing groove 106 respectively limit the sealing cover plate 2, thereby improving the firmness of the connection between the sealing cover plate 2 and the main structure 1 and further improving the sealing effect. The solution in this embodiment can fix the sealing cover plate 2 without using an external connector, and is easy to install.

[0042] In some embodiments, see Figure 1 The side wall of the main structure 1 is provided with a drainage hole 104 connected to the accommodating channel 101, and the drainage hole 104 is located at the lower part of the side wall.

[0043] When rainwater or water vapor from the outside enters the accommodating channel 101, the water vapor is pre-cooled and liquefied to form water droplets. The humid environment easily causes the cable to be corroded. Therefore, a drainage hole 104 is opened on the side wall of the main structure 1 to drain the water flow in the accommodating channel 101, ensuring that the environment in the accommodating channel 101 is dry and prolonging the service life of the cable.

[0044] Optionally, a desiccant is further provided in the accommodating channel 101 to absorb moisture in the accommodating channel 101 .

[0045] Optionally, a filter is provided on the drainage hole 104 to prevent external soil or dust from entering the accommodating channel 101 .

[0046] In some embodiments, see Figure 2 The bottom plate of the main structure 1 is inclined in the up-down direction.

[0047] The bottom plate of the main structure 1 is tilted, and after water accumulates in the accommodating channel 101 , the water flows toward the side of the bottom plate under the action of gravity, making it convenient to discharge the water from the accommodating channel 101 later.

[0048] Optionally, the side wall of the main structure 1 that contacts the lower side of the bottom plate is provided with a drainage hole 104. The drainage hole 104 is located at the lower part of the side wall and is connected to the accommodating channel 101, which is conducive to draining the water flow in the accommodating channel 101.

[0049] In some embodiments, as shown in the figure, the cable trench unit also includes a waterproof layer arranged in the accommodating channel 101, and the waterproof layer is connected to the main structure 1.

[0050] The waterproof layer can prevent moisture in the accommodating channel 101 from corroding the main structure 1 , thereby increasing the service life of the main structure 1 .

[0051] Optionally, the sealing cover plate 2 has an opening portion, which is a handle or an opening groove 201 to facilitate opening the sealing cover plate 2.

[0052] Optionally, the waterproof layer may be a waterproof coating applied to the inner wall of the main structure 1 .

[0053] Based on the same inventive concept, the utility model also provides an assembled cable duct. Figures 2 to 3 The assembled cable trench includes any one of the cable trench units mentioned above, the mounting block 102 is plugged into the mounting groove 103 of the adjacent cable trench unit, and the assembled cable trench also includes a cable bracket 3 arranged in the accommodating channel 101.

[0054] The assembled cable trench provided by the utility model adopts the above-mentioned cable trench unit, and the opposite ends of the cable trench unit are respectively provided with a mounting block 102 and a mounting groove 103, and the mounting block 102 is plugged or snapped into the mounting groove 103 of the adjacent main structure 1, so as to connect the two adjacent main structures 1 to each other. After the cable is laid in the accommodating channel 101, the sealing cover plate 2 is covered on the top of the main structure 1 to separate the top of the accommodating channel 101 from the outside. The utility model does not need to use external connecting parts, nor does it need to drill holes on the main structure 1. Multiple main structures 1 are connected in sequence by plugging or snapping to form a cable trench, which not only simplifies the connection structure and installation steps, improves the installation efficiency, but also avoids the problem of connection failure caused by loose connection parts after long-term use, and improves the firmness of the connection between the two adjacent main structures 1. In addition, a cable bracket 3 is set in the accommodating channel 101, and the cable is fixed on the cable bracket 3 to avoid the entanglement between multiple cables, which is convenient for subsequent maintenance of the cables.

[0055] In some embodiments, see Figure 2 The inner side wall of the main structure 1 is provided with a connection groove 105 along the up-down direction, and the cable bracket 3 is inserted into the connection groove 105 along the up-down direction.

[0056] The cable bracket 3 is inserted into the connection groove 105 to fix the cable bracket 3 to the main structure 1. In this embodiment, it is not necessary to drill holes on the cable bracket 3 and the main structure 1 and then fix them with bolts, which simplifies the installation steps and avoids the problem of damage to the cable bracket 3 and the main structure 1 caused by drilling holes, while ensuring the sealing of the main structure 1.

[0057] Optionally, the cable support 3 includes a main frame 301 and a plurality of support rods 302 sequentially connected to the main frame 301 in the up-down direction, and two adjacent support rods 302 support to form a cable receiving groove. The cables pass through the cable receiving groove, which can prevent the cables from being buried by water when placed at the bottom of the main structure 1, and can classify multiple cables to prevent the cables from being entangled with each other.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
