Description

Technical Field

[0001] This utility model relates to the field of power transmission technology, and in particular to prefabricated modules for cable trenches. Background Technology

[0002] Cable trenches are underground or semi-underground specialized structures used in power, communication and other engineering projects for laying, protecting and managing cables. They provide a safe and orderly laying space for cables, avoiding direct exposure to mechanical damage, environmental corrosion and human-caused damage on the ground or underground, while also facilitating later inspection and maintenance.

[0003] Most existing cable trenches use prefabricated modules. The processing of prefabricated cable trenches can be completed in the factory and directly assembled on site. However, the installation of cable supports inside the cable trench still requires on-site positioning and drilling, which reduces the laying efficiency of the cable trench.

[0004] In view of this, this application proposes a prefabricated module for cable trenches. Utility Model Content

[0009] As a further preferred embodiment of this technical solution, the flow control structure includes a partition plate installed within an installation frame. The partition plate has an array of drain grooves with the same size as the flow groove of the cable trench frame. An installation box is installed inside the partition plate, and a rotating fan is rotatably connected inside the installation box. The rotating fan rotates within the flow groove of the cable trench frame.

[0010] As a further preferred embodiment of this technical solution, a rotating block is installed on the rotating fan, a wedge-shaped lifting block is slidably connected inside the rotating block, a connecting rod or a sliding block is installed between the wedge-shaped lifting blocks respectively, the connecting rod and the sliding block are slidably connected, a limit spring is provided between the connecting rod and the sliding block, a lifting cylinder is slidably connected on the rotating block, and a wedge-shaped adjusting block is installed on the lifting cylinder.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] This utility model provides the following technical solution: like Figures 1 to 6 As shown, the prefabricated cable trench module includes a cable trench frame 1, a cable trench cover plate 2 installed on the cable trench frame 1, symmetrically distributed assembly blocks 3 installed on one side of the cable trench frame 1, an installation frame 4 installed on the other side of the cable trench frame 1, an array of cable support structures 5 installed inside the cable trench frame 1, and a flow control structure 6 installed inside the installation frame 4. The cable support structure 5 includes a positioning mounting frame 51 positioned and installed in the cable trench frame 1. A sliding mounting frame 52 is installed on the positioning mounting frame 51. An array of lower cable limiting blocks 57 are installed on the sliding mounting frame 52. A sliding rod 55 is slidably connected inside the sliding mounting frame 52. An array of upper cable limiting blocks 56 are installed on the sliding rod 55. An array of cable grooves 58 are opened on both the upper cable limiting blocks 56 and the lower cable limiting blocks 57.

[0017] It should be noted that by positioning and opening an installation groove for the positioning mounting bracket 51 within the cable trench frame 1, and after the cable trench frame 1 is integrally formed in the factory, and a positioning mounting bracket 51 of the corresponding size is matched and processed, the installation efficiency of the cable trench is increased, thus avoiding the need for positioning and installation by measuring the distance and opening holes during the actual installation process.

[0018] The upper cable limiting block 56 slides relative to the lower cable limiting block 57 by sliding the sliding rod 55 within the sliding mounting bracket 52. By adjusting the distance between the upper cable limiting block 56 and the lower cable limiting block 57, the cable is placed in the cable groove 58 opened on the lower cable limiting block 57. Then, the upper cable limiting block 56 slides to the lower cable limiting block 57, clamping the cable in the cable groove 58 within the upper cable limiting block 56 and the lower cable limiting block 57. The cable is evenly placed in the cable groove 58, preventing the cables from tangling during subsequent use and affecting the cable's performance.

[0019] like Figure 1 and 2 As shown, the mounting frame 4 has a through groove with the same shape as the assembly block 3. The assembly block 3 and the through groove of the mounting frame 4 are matched for limiting. The bottom of the cable trench frame 1 has a flow groove.

[0020] It should be noted that the modularly produced assembly block 3 and mounting frame 4, along with the through groove on the mounting frame 4 that is the same shape as the assembly block 3, make the modular cable trench frame 1 easy and quick to install. By opening a flow groove at the bottom of the cable trench frame 1, rainwater flowing into the cable trench frame 1 can be discharged along the flow groove during use.

[0021] like Figure 3 As shown, fixing screws 53 are installed on both the positioning mounting bracket 51 and the sliding mounting bracket 52. A limiting fixing block 54 is slidably connected on the sliding mounting bracket 52. The limiting fixing block 54 is installed on the lower side of the cable trench cover plate 2.

[0022] It should be noted that the positioning mounting bracket 51, which is automatically positioned and installed during the production of the cable trench frame 1, avoids the need for positioning and drilling when installing the upper cable limiting block 56 and the lower cable limiting block 57. The positioning mounting bracket 51 and the sliding mounting bracket 52 are fixed together by the fixing screws 53. When the cable is laid on the lower cable limiting block 57, the upper cable limiting block 56 and the sliding rod 55 slide to restrict the cable from the top. After installation, the cable trench cover 2 is installed on the cable trench frame 1. At the same time, the limiting fixing block 54 on the lower side of the cable trench cover 2 presses on the sliding rod 55. The limiting fixing block 54 presses the sliding rod 55 into the sliding mounting bracket 52, thereby ensuring the stability of the upper cable limiting block 56.

[0023] like Figures 4 to 6 As shown, the flow control structure 6 includes a partition plate 61 installed in the mounting frame 4. The partition plate 61 has an array of drainage grooves with the same size as the flow groove of the cable trench frame 1. An installation box 62 is installed in the partition plate 61. A rotating fan 63 is rotatably connected in the installation box 62. The rotating fan 63 rotates in the flow groove of the cable trench frame 1.

[0024] A rotating block 68 is installed on the rotating fan 63. A wedge-shaped lifting block 69 is slidably connected inside the rotating block 68. A connecting rod 610 or a sliding block 611 is installed between the wedge-shaped lifting blocks 69. The connecting rod 610 and the sliding block 611 are slidably connected. A limit spring 612 is provided between the connecting rod 610 and the sliding block 611. A lifting cylinder 66 is slidably connected on the rotating block 68. A wedge-shaped adjusting block 67 is installed on the lifting cylinder 66.

[0025] The mounting box 62 has symmetrically distributed adjusting rods 65 that slide within it. The adjusting rods 65 are wedge-shaped and engage with the wedge-shaped adjusting block 67. The partition plate 61 has a rotatably connected adjusting valve 64 that engages with the adjusting rods 65.

[0026] It should be noted that the cable trench frame 1 is separated by the partition plate 61 installed in the mounting frame 4, so that the water in the cable trench frame 1 can only flow out through the flow channel on the cable trench frame 1. When there is too much water in the cable trench frame 1 and it exceeds the upper limit of the flow channel, the water flow speed between the flow channel and the partition plate 61 increases, which in turn drives the rotating fan 63 to rotate faster. The increased speed of the rotating fan 63 drives the rotating block 68 to rotate synchronously.

[0027] The centrifugal force on the wedge-shaped lifting block 69 inside the rotating block 68 is greater than the elastic force of the limiting spring 612, causing the wedge-shaped lifting block 69 to slide outward, thereby squeezing the lifting cylinder 66 outside the rotating block 68 to slide upward. The lifting cylinder 66 then drives the wedge-shaped adjusting block 67 to slide upward synchronously, thereby squeezing the adjusting rod 65 to slide outward from the mounting box 62, thereby driving the adjusting valve 64 to rotate. This causes the sealing structure formed by the adjusting valve 64 and the partition plate 61 to be released, thereby increasing the water flow channel in the cable trench frame 1 and increasing the water discharge speed in the cable trench frame 1.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
