Description

Technical Field

[0001] This utility model relates to the field of cable troughs, and more specifically, to an underground cable trough that can replace cable trays. Background Technology

[0002] Typical underground parking garage pipelines, including power, low-voltage, water supply and drainage, ventilation, and heating pipes, are laid along the basement ceiling using steel cable trays or round pipes. The various professional pipelines are laid parallel or perpendicularly. Due to the large number of pipelines, it is difficult to meet the safety distance requirements, which can easily lead to mutual interference. In addition, the types and quantities of cable trays and pipes in underground parking garages of commercial, office, and residential high-rise buildings are complex, which can easily make it difficult to select the route of power cable trays.

[0003] For example, the "Underground Cable Tray that Replaces Cable Tray" disclosed in Chinese Utility Model Patent (Application No.: CN202421879952.0) includes a supporting steel plate, channel steel, and a first steel cover plate; two channel steels are placed vertically in a ground groove to form a straight groove; the bottom ends of the channel steels are welded to the supporting steel plate fixedly set at the bottom of the ground groove; vertical plates are provided on both sides of the steel cover plate; the steel cover plate is set on the two channel steels and connected to the side plates of the channel steels through the vertical plates; this utility model has a simple and stable structure, is easy to obtain materials, occupies little space, and is safe and reliable;

[0004] Although the aforementioned patents can provide protection for cables installed directly on the ground, the installation process requires frequent welding of the structure. For example, the supporting steel columns need to pass through the ground protection layer and be welded to the structural steel bars, and the supporting steel plates also need to be welded to the supporting steel balls. This makes it difficult to fix and takes a long time to install, which has certain shortcomings.

[0005] Therefore, we have made improvements and proposed an underground cable trough to replace cable trays. Utility Model Content

[0006] The purpose of this utility model is to solve the current problems of high difficulty in fixing and long installation time.

[0007] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides an underground cable trough to replace cable trays. The trough includes a ground protective layer with a trapezoidal groove on its upper surface. A cable trough frame is housed inside the trapezoidal groove, and the frame is U-shaped. Two vertical plates of the frame contact the inner walls of the trapezoidal groove. Openings extending into the interior are formed on both sides of the frame. Two openings are also formed on the horizontal plate of the frame. The two openings on the vertical and horizontal plates of the frame communicate with each other. A connecting shaft is fixedly connected between the inner walls of the openings on the vertical plates of the frame. A connecting sleeve is rotatably fitted onto the outer surface of the connecting shaft. A locking block is fixedly connected to the lower surface of the connecting sleeve. The surfaces of the two locking blocks that are close together are flush with the inner side of the vertical plates of the frame, while the surfaces of the two locking blocks that are far apart contact the inner wall of the trapezoidal groove. The lower surface of the locking block is inclined. A cable protection assembly is provided on the cable trough frame.

[0008] As a preferred technical solution of this application, the cable protection assembly includes two positioning plates, both of which are fixedly connected to the bottom wall of the cable tray frame. The upper surfaces of both positioning plates are set as arc surfaces, and the surfaces of the two positioning plates that are far apart from each other are flush with the opening slot.

[0009] As a preferred technical solution of this application, the adjacent surfaces of the two positioning plates are both set as inclined surfaces, and the adjacent surfaces of the two vertical plates of the wire groove frame are both provided with first triangular slots.

[0010] As a preferred technical solution of this application, the inside of the wire groove frame is provided with a cover plate, and the cover plate is also U-shaped.

[0011] As a preferred technical solution of this application, the two vertical plates of the cover plate are respectively fixedly connected to the side surfaces of the two plates that are far apart from each other, and the first triangular block is adapted to the first triangular slot.

[0012] As a preferred technical solution of this application, the upper surface of the cover plate is flush with the upper surface of the ground protection layer, and the upper surfaces of the two vertical plates of the wire groove frame are in contact with the lower surface of the cover plate.

[0029] Example 1

[0030] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4An underground cable trough, replacing cable trays, includes a ground protective layer 1. A trapezoidal groove 2 is formed on the upper surface of the ground protective layer 1. A cable trough frame 3 is installed inside the trapezoidal groove 2, allowing for cable placement and protection. The cable trough frame 3 is U-shaped. Two vertical plates of the cable trough frame 3 contact the inner walls of the left and right sides of the trapezoidal groove 2. Opening grooves 4 extending into the interior are formed on both sides of the cable trough frame 3, connecting the interior and exterior. Two opening grooves 4 are also formed on the horizontal plate of the cable trough frame 3. The two opening grooves 4 on the vertical and horizontal plates of the cable trough frame 3 communicate with each other. A connecting shaft 5 is fixedly connected between the front and rear inner walls of the opening grooves 4 on the vertical plates of the cable trough frame 3. A connecting sleeve 6 is rotatably fitted onto the outer surface of the connecting shaft 5. The connecting sleeve 6 cooperates with the connecting shaft 5 to achieve rotation. The connecting sleeve 6 has a locking block 7 fixedly connected to its lower surface. The locking block 7 locks the wire trough frame 3 by abutting against the inner wall of the trapezoidal groove 2. The surfaces of the two locking blocks 7 that are close to each other are flush with the inner side of the vertical plate of the wire trough frame 3, while the surfaces of the two locking blocks 7 that are far apart from each other are in contact with the inner wall of the trapezoidal groove 2. The lower surface of the locking block 7 is set as an inclined surface. The wire trough frame 3 is equipped with a cable protection component. Through the cooperation of the locking block 7 and the trapezoidal groove 2, the wire trough frame 3 can be fixed by the locking block 7 after it is inserted. At the same time, since the lower surface of the locking block 7 is inclined, it will automatically retract into the opening groove 4 during the process of the locking block 7 entering the trapezoidal groove 2. After being fully inserted, it will automatically return to its original position by gravity. The overall operation process is simple and convenient, improving installation efficiency.

[0031] Example 2

[0032] The underground cable trough that replaces the cable tray provided in Example 1 is further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the cable protection assembly includes two positioning plates 8, both of which are fixedly connected to the bottom wall of the cable tray frame 3. The positioning plates 8 provide initial positioning after the cable is placed. The upper surfaces of both positioning plates 8 are curved, with the surfaces of the two positioning plates 8 furthest from each other flush with the opening slot 4, and the surfaces of the two positioning plates 8 adjacent to each other being beveled. The surfaces of the two vertical plates of the cable tray frame 3 adjacent to each other are provided with first triangular slots 9. A cover plate 10 is provided inside the cable tray frame 3, closing the upper opening of the cable tray frame 3. The cover plate 10 is also U-shaped. First triangular blocks 11 are fixedly connected to the furthest surfaces of the two vertical plates of the cover plate 10, respectively. The cover plate 10 is fixed by the cooperation of the first triangular blocks 11 with the first triangular slots 9. The first triangular blocks 11 and the first triangular slots 9 are compatible. The upper surface of the horizontal plate of the cover plate 10 is flush with the ground protection. The upper surface of layer 1 is flush with the upper surface of the two vertical plates of the cable tray frame 3, and the lower surface of the horizontal plate of the cover plate 10 is in contact with the upper surface of the two vertical plates of the cover plate 10. A second triangular slot 12 is provided on the adjacent side surface of the two vertical plates of the cover plate 10. A cable protection frame 13 is provided between the two vertical plates of the cover plate 10 to limit and protect the cable. The left and right sides of the cable protection frame 13 are respectively fixedly connected with second triangular blocks 14. A conical positioning groove 15 is provided on the lower surface of the cable protection frame 13, and an arc groove 16 is provided on the top wall of the conical positioning groove 15. After the cable tray frame 3 is placed, the locking block 7 can be pushed to contact the inner wall of the trapezoidal groove 2 by inserting the cover plate 10. The locking block 7 is used to lock the position of the locking block 7 and prevent it from rotating inward. At the same time, the overall locking operation only requires inserting the cover plate 10 normally, without any additional operation steps. It is simple and convenient and also more intuitive to operate.

[0033] The cable tray frame 3 is provided in multiple sets, and the cable protection frame 13 and the cover plate 10 are installed on two cable tray frames 3 at the same time.

[0034] The underground cable trough that replaces cable trays provided by this utility model is used as follows:

[0035] When installing and fixing the cable, firstly, a trapezoidal groove 2 that matches the cable tray frame 3 is opened on the ground protective layer 1. Then, the cable tray frame 3 is inserted into the trapezoidal groove 2. Since the lower surface of the locking block 7 is inclined, although the protruding part of the locking block 7 goes beyond the vertical plate of the cable tray frame 3, when the lower inclined surface of the locking block 7 contacts the edge of the trapezoidal groove 2, it will automatically squeeze the locking block 7 and rotate it back into the opening groove 4. Then, when the cable tray frame 3 continues to descend and the locking block 7 enters the wide part of the trapezoidal groove 2, since the locking block 7 is no longer constrained by the trapezoidal groove 2, it will reset under the action of gravity. At this time, the cable can be placed between the two positioning plates 8. The positioning plates 8 help to prevent one side of the cable from contacting the inner wall of the cable tray frame 3, which would cause damage to the cable when the cover plate 10 is installed laterally. After the cable is placed, the cable protection frame 13 is slid horizontally into the cover plate 10, and the cable protection frame 13 is placed between the two positioning plates 8. During the sliding of the protective frame 13, the second triangular locking block 14 needs to be aligned with the second triangular locking groove 12. Then, the cover plate 10 is aligned with the wire groove frame 3 and inserted. During the insertion of the cover plate 10, the first triangular locking block 11 contacts the upper surface of the vertical plate of the wire groove frame 3. With the deformation of the cover plate 10 itself, the first triangular locking block 11 retracts. When the first triangular locking block 11 is aligned with the first triangular locking groove 9, the cover plate 10 returns to its original position and the first triangular locking block 11 is ejected into the interior of the first triangular locking groove 9. At the same time, during the insertion of the cover plate 10, its vertical plate will contact the locking block 7, thereby squeezing the locking block 7 to rotate outward so that the locking block 7 contacts the inner wall of the trapezoidal groove 2 to complete the fixation of the wire groove frame 3. During the insertion of the cover plate 10, the cable is repositioned by the conical positioning groove 15 opened on the cable protection frame 13. Then, the cable protection frame 13 continues to descend, allowing the cable to enter the interior of the arc groove 16 to complete the fixation of the cable.
