[0019] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] Please refer to Figure 1-4 An integrated drainage cable trench for a hydropower station site includes at least two vertically arranged trenches 1. In this embodiment, the trenches 1 are cable trenches. A water collection trough 2 is provided at the vertical intersection of the two trenches 1. The inner bottom walls of the trenches 1 are inclined towards the water collection trough 2. When water flows into the trenches 1, it can quickly flow into the water collection trough 2 through the inclined bottom walls. Cable supports 4 are symmetrically arranged on both sides of the inner wall of the trenches 1. The cable supports are fixed to the inner wall of the trenches by bolts. A baffle plate 12 is provided above the cable supports 4. The ends of the baffle plates 12 are inclined downwards, that is, both baffle plates 12 are inclined towards the middle of the trenches 1 to block the cable supports 4 below. A cover plate 5 is provided on the top of the trenches 1. The surface of the cover plate 5 is provided with a zigzag groove 10. A plurality of permeable holes 11 are evenly distributed in the zigzag groove 10. A cleaning mechanism matching the zigzag groove 10 is provided above the cover plate 5.

[0021] In use, the wires and cables are laid on the cable bracket 4. When external water flows from the cover plate 5 through the zigzag trough 10 and the water-permeable hole 11 into the trench 1, it will fall on the baffle plate 12. At this time, the baffle plate 12 intervenes in the water flow to prevent it from splashing onto the cables. The water that falls into the trench 1 eventually flows into the water collection tank 2, thus realizing the laying of cables and drainage of the trench, which is highly practical.

[0022] Specifically, the cable support 4 includes a fixing frame 15 fixed to the inner wall of the trench 1. Multiple cable guides 16 are vertically fixed on the fixing frame 15. Multiple cable guides 16 are provided on the cable guides 21. Cables can be managed through the cable guides 21. Multiple positioning blocks 20 are provided on the surface of the cable guides 16. A gap for overlapping is left between each two adjacent positioning blocks 20. In use, the cable can be laid between two positioning blocks 20 to avoid the cable from being messy and crossing.

[0023] In other words, when using cable management, cables can be laid and managed in the cable hole 21, or they can be laid on the cable rack 16 (between the two positioning blocks), which can meet different wiring needs and greatly increase the number of cables that can be laid.

[0024] In addition, a positioning column 17 is provided at the top of the cable support 4, and a positioning groove 18 cooperating with the positioning column 17 is provided on one side of the water baffle 12. The water baffle 12 is snap-fitted on the cable support 4 through the cooperation of the positioning column 17 and the positioning groove 18. One side of the water baffle 12 where it is snap-fitted is higher than the free end, so as to incline the water baffle towards the middle of the trench body and produce a water blocking effect.

[0025] As a preferred solution, an insulating layer is provided on the outer wall of the wire threading frame 16.

[0026] In this embodiment, tracks 6 are provided on both sides of the cover plate 5, and the cleaning mechanism can move and clean along the tracks 6 on the cover plate 5.

[0027] Specifically, the cleaning mechanism includes a handle 14 above and a connecting member 8 below. Both ends of the connecting member 8 are bent inward, and after bending, it is in a "冂" shape. A pulley 7 cooperating with the track 6 is provided at the bent part of the connecting member 8. A cleaning brush 9 is provided below the connecting member 8, and the cleaning brush 9 is detachably connected to the connecting member 8 through a fixing clip 13.

[0028] In this embodiment, the fixing clip 13 can be an existing connecting member such as a clamp, a tie, a buckle, etc. The purpose is to satisfy the disassembly of the cleaning brush 9 and facilitate the subsequent disassembly, cleaning or replacement of the cleaning brush.

[0029] A folded-line groove body is also provided at the bottom of the cleaning brush 9, and this groove body is in concave-convex fit with the groove body on the surface of the cover plate 5; during use, the staff holds the handle 14 and pushes the whole to make the pulley 7 roll in the track 6. At this time, the cleaning brush 9 cleans dust and other impurities on the surface of the cover plate 5 to ensure the cleanliness of the cover plate surface.

[0030] Based on the above embodiment, a water level gauge 19 for monitoring the water level and a water pipe 3 for draining water are further provided in the water collecting tank 2. The water pipe 3 is connected to a built-in pump (not shown in the figure), and the water level gauge 19 drives the built-in pump through a controller.

[0031] The water level gauge 19 is used to monitor the water level height in the water collecting tank 2. When the water level height reaches the preset position, the built-in pump is driven to operate by the controller. After the built-in pump operates, the accumulated water in the water collecting tank is pumped out through the water pipe 3.

[0032] In this embodiment, the water level gauge 19 can also be different types of liquid level monitors, water level gauges, etc., as long as it can monitor the liquid level height and control the operation of the pump to drain water. There is no need to elaborate here.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
