Description

Technical Field

[0001] The utility model relates to the technical field of cable trenches, in particular to a prefabricated cable trench for a distribution network project. Background Technique

[0002] A cable trench is an underground pipeline used for laying and replacing power or telecommunications cable facilities, and it is also an enclosure structure for the laid cable facilities. It has pipeline structure forms such as rectangular, circular, and arched. A distribution network refers to a power grid that receives electric energy from a transmission network or a regional power plant and distributes it locally through distribution facilities or step by step according to voltage levels to various users. Now, prefabricated cable trenches are required in distribution network projects. When in use, cables are mostly laid in the cable trench, but they cannot be sorted and arranged in layers, resulting in the cables being entangled in the cable trench, making it difficult to distinguish, which affects subsequent maintenance. Therefore, we propose a prefabricated cable trench for a distribution network project. Content of the Utility Model

[0003] The purpose of the utility model is to provide a prefabricated cable trench for a distribution network project to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A prefabricated cable trench for a distribution network project, including a cable trench. Three sorting plates are arranged in the cable trench. Sliding grooves are respectively opened on the left and right sides of the top of the cable trench. Sliders that match the sliding grooves are arranged on the left and right side walls of the three sorting plates. A first cavity and a second cavity are arranged in the slider, and a fixing component is arranged in the first cavity and the second cavity.

[0005] Further, the fixing component includes a bidirectional lead screw arranged in the first cavity. Abutted blocks are respectively sleeved on the front and rear sides of the outer wall of the bidirectional lead screw. One ends of the two abutted blocks respectively penetrate through the front and rear side walls in the first cavity and abut against the inner side wall of the sliding groove.

A screw 5 penetrates through the left side wall of the cover 6. Threaded holes 3 matching the screws 5 are opened at the tops of the sorting plates 2. The cover 6 is fixed to the sorting plates 2 by using the threaded holes 3 and the screws 5, so as to be able to fix the cables. Chutes 7 are opened on the left and right sides of the top of the cable trench 1. The chutes 7 are arranged in a T shape. Sliders 9 matching the chutes 7 are provided on the left and right side walls of the three sets of sorting plates 2. A first cavity 10 and a second cavity 11 are provided in the slider 9. A fixing component 8 is provided in the first cavity 10 and the second cavity 11.

[0019] Please refer to Figure 2-4 , the fixing component 8 includes a bidirectional lead screw 81 provided in the first cavity 10. Abuttment blocks 80 are sleeved on the front and rear sides of the outer wall of the bidirectional lead screw 81. A guide groove is opened on the left side wall of the first cavity 10. Guide blocks matching the guide groove are provided on the left side walls of the two abutment blocks 80. Under the action of the guide groove and the guide blocks, the two abutment blocks 80 can move away from each other on the outer wall of the bidirectional lead screw 81. One ends of the two abutment blocks 80 respectively penetrate through the front and rear side walls of the first cavity 10 and abut against the inner side walls of the chutes 7. A first driven bevel gear 82 is sleeved and installed on the outer wall of the bidirectional lead screw 81. A first driving bevel gear 83 meshing with the first driven bevel gear 82 is provided in the first cavity 10. A rotating shaft 84 is provided on the right side wall of the first driving bevel gear 83. One end of the rotating shaft 84 penetrates through the right side wall of the first cavity 10 and is connected to a bearing provided on the right side wall of the second cavity 11.
