Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower engineering technology, and in particular to a cable side groove structure and its cover plate structure. Background Technology

[0002] In the construction of traditional underground powerhouses in hydropower stations, cable trenches are mainly formed by excavating rock at the bottom of both sides of the cavern. Due to the limited size of the cable trenches, it is difficult to use large machinery, and manual excavation is the primary method. This results in a complex construction process and a long overall construction period. Existing cable trenches mostly use steel or concrete covers, which have poor sealing properties and are prone to water seepage and accumulation problems within the underground powerhouse, affecting the stable operation of the cable system.

[0003] Furthermore, steel and concrete cable trench covers are quite heavy, making disassembly difficult and reducing management efficiency during routine cable inspections, maintenance, and emergency repairs. Therefore, existing cable trench designs suffer from low durability, reliability, and ease of construction and maintenance.

[0004] Therefore, there is an urgent need to provide a cable side trench structure and its cover plate structure, which can improve the durability, reliability and ease of construction and maintenance of cable trenches compared with existing technologies. Utility Model Content

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A cable side channel structure includes a lining, a cable side channel, and a drainage ditch. The cable side channel and the drainage ditch are integrally formed on the lining. The cable side channel is positioned close to the lining relative to the drainage ditch. The drainage ditch is located below the cable side channel. The cable side channel has a lateral opening. An embedded part is provided on the inner side wall of the cable side channel, and a cable support is provided on the embedded part. The cable side channel communicates with the drainage ditch.

[0008] Furthermore, multiple embedded parts are provided along the length direction of the cable side groove.

[0009] Furthermore, the lateral opening of the cable side groove is oriented toward the drainage ditch.

[0010] Furthermore, the cable side groove is connected to the drainage channel through a pre-embedded pipe.

[0011] Furthermore, the pre-embedded pipe extends into the drainage ditch.

[0012] A cover plate structure for a cable side channel structure includes a cable side channel structure and a cover plate, wherein the cover plate is configured to cover the lateral opening of the cable side channel.

[0013] Furthermore, a keel is provided on the outer side wall of the cable side groove, and the cover plate is connected to the keel.

[0014] Furthermore, one end of the cover plate is hinged to the keel, and the other end of the cover plate is detachably connected to the keel.

[0015] Furthermore, a sealing ring is provided between the keel and the cover plate.

[0016] Furthermore, the keel is connected to the outer periphery of the cable side groove by expansion bolts.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] like Figure 1 , Figure 2 As shown, this embodiment provides a cable side channel structure, including a lining 1, a cable side channel 2, an embedded part 3, a cable bracket 4, a drainage ditch 5, and an embedded pipe 6. The cable side channel 2, the drainage ditch 5, and the lining 1 are integrally cast and formed. The drainage ditch 5 is located below the cable side channel 2, and the cable side channel 2 is located close to the lining 1 relative to the drainage ditch 5.

[0028] The cable side channel 2 is provided with a lateral opening, which faces the drainage ditch 5. Multiple embedded parts 3 are provided inside the cable side channel 2. The embedded parts 3 are cast in the inner wall of the cable side channel 2. The embedded parts 3 are spaced along the length of the cable side channel 2. A cable bracket 4 is fixedly connected to each embedded part 3. The cable bracket 4 is used to place the cable.

[0029] The cable side trough 2 is connected to the drainage ditch 5 through the pre-embedded pipe 6. The pre-embedded pipe 6 is set on the lower side wall of the cable side trough 2 and extends into the drainage ditch 5. Water in the cable side trough 2 can be introduced into the drainage ditch 5 through the pre-embedded pipe 6.

[0030] This embodiment integrates the lining 1, cable side groove 2, and drainage ditch 5 into a single casting design, minimizing joints and significantly improving overall waterproof performance and structural durability. It forms an efficient drainage channel that can quickly drain accumulated water, effectively preventing faults caused by long-term cable immersion, greatly improving the system's waterproof and moisture-proof performance, and enhancing the safety and stability of cable operation.
