One end of the spring 10 is fixedly connected with the clamping block 7, and the other end of the spring 10 is fixedly connected with the inner wall of the fixing block 3 away from the end of the clamping block 7. One end of the pull rod 8 is rotatably connected with a handle 9. A fixing rod 4 is fixedly connected to the side of the top cover 2 corresponding to the slot 12. The fixing rod 4 can be inserted into the slot 12. A fixing groove 5 is opened on the fixing rod 4. The other end of the clamping block 7 is inserted into the fixing groove 5. The number of fixing blocks 3 is four, and the four fixing blocks 3 are distributed at the four corner positions close to the top cover 2. A support plate 13 is fixedly connected to the fixing block 3. A limiting groove 14 is opened at one end of the support plate 13 away from the fixing block 3. Anti-slip protrusions 11 are provided on the handle 9, and the anti-slip protrusions 11 are evenly distributed on one side surface of the handle 9. A second inclined surface 15 is provided on the clamping block 7, and a first inclined surface 6 is provided on the fixing rod 4 corresponding to the second inclined surface 15. A support rod 26 is fixedly connected to the inner side surface of the cable trench 1. A placement groove 27 is opened on the support rod 26. A limiting plate 28 is fixedly connected to one end of the support rod 26 away from the inner wall of the cable trench 1. A water guide groove 24 is provided on the inner bottom surface of the cable trench 1. Drainage holes 25 are opened at the bottom of the water guide groove 24.

[0026] In this embodiment, by providing structures such as the fixed block 3, the clamping block 7, the pull rod 8, the spring 10 and the handle 9, the clamping block 7 is pushed by the elastic force of the spring 10 on the pull rod 8 to slide inside the fixed block 3 and finally insert into the fixing groove 5 on the fixed rod 4, realizing the convenient clamping and fixing between the top cover 2 and the cable trench 1. Compared with the traditional fixing method using bolts 29 and nuts 30, it does not require professional tools, and the installation and disassembly of the top cover 2 can be easily achieved only by operating the handle 9, greatly improving the working efficiency of operations such as cable maintenance, repair and capacity expansion, and reducing the labor cost; by arranging four fixed blocks 3 at the four corners near the top cover 2, and inserting the four fixed rods 4 on the top cover 2 into the slots 12 on the fixed blocks 3, the top cover 2 is more evenly stressed when connected to the cable trench 1, enhancing the stability and firmness of the connection, ensuring that the top cover 2 can reliably cover the cable trench 1 and providing good protection for the cables; by pulling the handle 9 and rotating it to overlap in the limit groove 14 on the support plate 13, the convenience of disassembling the top cover 2 can be further improved, and the disassembly work of the top cover 2 can be completed with fewer workers; by the anti-slip protrusions 11 evenly distributed on one side surface of the handle 9, the friction between the fingers and the handle 9 is increased, effectively preventing hand slipping when operating the handle 9; the second inclined surface 15 on the surface of the clamping block 7 and the first inclined surface 6 on the surface of the fixed rod 4 cooperate with each other. When installing the top cover 2, when the fixed rod 4 is inserted into the slot 12, the first inclined surface 6 presses the second inclined surface 15, enabling the clamping block 7 to automatically slide into the fixed block 3. After the fixed rod 4 is completely inserted, the clamping block 7 automatically pops out under the elastic push of the spring 10 and inserts into the fixing groove 5, realizing automatic clamping, simplifying the installation process and improving the installation efficiency; through the support rod 26 on the inner side surface of the cable trench 1, the placement groove 27 thereon and the limit plate 28 at the end, a position for supporting and fixing the cables is provided. The cables can be orderly placed in the placement groove 27, and the limit plate 28 can prevent the cables from slipping off the end of the support rod 26, facilitating the neat laying and management of the cables, and at the same time reducing the mutual interference between the cables; through the water guide groove 24 and the drain hole 25 at the bottom of the cable trench 1, the accumulated water in the cable trench 1 can be discharged in time, preventing the cables from being soaked in water for a long time, avoiding damage to the cables due to moisture, extending the service life of the cables, and improving the safety and reliability of cable operation.

[0027] Embodiment 2: As Figure 2 - Figure 5As shown in the figure, the prefabricated trench includes a plurality of adjacent cable trenches 1. The two ends of the cable trench 1 can be inserted and matched with the adjacent cable trenches 1. A connecting groove 23 is opened on the inner side of one end of the cable trench 1, and a second fixing hole 22 is opened on the side wall of the connecting groove 23. A first fixing hole 21 is opened on the side surface of the other end of the cable trench 1. One end of the cable trench 1 provided with the first fixing hole 21 can be inserted into the inside of the connecting groove 23 at one end of the adjacent cable trench 1, and the first fixing hole 21 is aligned with the second fixing hole 22 at one end of the adjacent cable trench 1. Bolts 29 are inserted into the first fixing hole 21 and the second fixing hole 22 at the connection of two adjacent cable trenches 1. A nut 30 is threadedly connected to the surface of the bolt 29. Three bolts 29 are provided on each side of each end of the cable trench 1, and the three bolts 29 are equidistantly distributed on the surface of this side. Square rods 17 are fixedly connected to the bottom ends on both sides of the top cover 2. A U-shaped clamping strip 16 is fixedly connected to the bottom of one end of the top cover 2. A connecting plate 19 is fixedly connected to the other end of the top cover 2. A U-shaped clamping groove 20 is opened on the outer surface of the connecting plate 19. A groove 18 is opened on the cable trench 1 at the position corresponding to the square rod 17, and the square rod 17 is clamped in the groove 18. The U-shaped clamping strip 16 is used to be clamped inside the U-shaped clamping groove 20 of the adjacent cable trench 1.

[0028] In this embodiment, through the settings of the connecting groove 23, the first fixing hole 21, the second fixing hole 22, the bolt 29 and the nut 30 at both ends of the cable trench 1, the connection and fixation between adjacent cable trenches 1 are facilitated. Through the connection method of the bolt 29 and the nut 30, it can be ensured that the connection between adjacent cable trenches 1 is tight and firm. The cable trenches 1 can be flexibly spliced according to actual needs to meet the cable laying requirements of different lengths and layouts; through the three equidistantly distributed bolts 29 on each side of the cable trench 1, the stability and firmness of the connection between adjacent cable trenches 1 are further enhanced, so that the entire prefabricated trench forms a whole after splicing, which can better withstand external pressure and tension, and ensures the stability of the trench structure; by clamping the square rod 17 on the top cover 2 in the groove 18 on the cable trench 1 and clamping the U-shaped clamping strip 16 at the bottom of the top cover 2 in the U-shaped clamping groove 20 on the connecting plate 19 at one end of the adjacent top cover 2, the sealing effect at the joint between the top cover 2 and the cable trench 1 and at the joint between adjacent top covers 2 is improved, preventing external dust, sundries, rainwater, etc. from entering the inside of the cable trench 1, and at the same time, it can also prevent the top cover 2 from shifting, ensuring the normal use of the device.

[0029] Working principle of this embodiment: When in use, place the cable trench 1 at the designated position. Then insert the end of the cable trench 1 with the first fixing hole 21 into the inside of the connection groove 23 on one side of the adjacent cable trench 1, align the first fixing hole 21 with the second fixing hole 22, then insert the bolt 29 into the first fixing hole 21 and the second fixing hole 22, and tighten with the nut 30 to achieve the connection and fixation of adjacent cable trenches 1. After the cable trenches 1 are laid, place the cables orderly in the placement grooves 27 of the side support rods 26 inside the cable trench 1, and the limiting plate 28 prevents the cables from slipping. After the cables are laid, insert the four fixing rods 4 on the top cover 2 into the inside of the slot 12 on the fixing block 3 on the cable trench 1. Then press the top cover 2, and the first inclined surface 6 on the fixing rod 4 and the second inclined surface 15 on the clamping block 7 generate extrusion, causing the clamping block 7 to automatically slide towards the inside of the fixing block 3. When the fixing groove 5 on the fixing rod 4 is aligned with the clamping block 7, it automatically inserts into the inside of the fixing groove 5 under the elastic force of the spring 10 on the pull rod 8 to achieve the purpose of fixing the top cover 2 without additional operations. After the top cover 2 is fixed to the cable trench 1, the square rod 17 on the top cover 2 is stuck in the groove 18 on the cable trench 1, and the U-shaped clamping strip 16 at the bottom of the top cover 2 is stuck in the U-shaped clamping groove 20 on the upper connecting plate 19 at one end of the adjacent top cover 2, improving the sealing effect at the joint between the top cover 2 and the cable trench 1 and at the joint between adjacent top covers 2, preventing external dust, sundries, rainwater, etc. from entering the inside of the cable trench 1, and also avoiding the displacement of the top cover 2, ensuring the normal use of the device. When there is accumulated water in the cable trench 1, the water will flow into the bottom water guide groove 24 and then be discharged from the cable trench 1 through the drain hole 25 to avoid the cables being damaged by moisture. When it is necessary to remove the top cover 2 to inspect and repair the cables inside the cable trench 1, pull the handle 9. The anti-slip protrusions 11 on the handle 9 increase the friction between the fingers and the handle 9, effectively preventing hand slippage when operating the handle 9. Then rotate the handle 9 and place it in the limiting groove 14 on the support plate 13. The remaining clamping blocks 7 can be operated according to the above operation steps. Then the top cover 2 can be removed from the cable trench 1.

[0030] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
