Abstract
Description
Technical Field
[0001] This application relates to the field of water conservancy engineering technology, specifically to a layered water intake cable protection device. Background Technology
[0002] In stratified water intake systems in hydraulic engineering, cables typically extend underwater. However, since stratified intake valves usually do not extend to the water surface, the cable section from the valve body to the water surface and the top of the gate slot remains suspended for extended periods. This section lacks rigid support and protection. With rising water levels, the suspended cable is directly exposed to turbulent water flow. Vortex and water hammer effects can easily cause the cable to swing repeatedly, accelerating sheath wear and internal core breakage. Therefore, a cable protection technology for stratified water intake systems is urgently needed to prevent water flow damage to the cables. Utility Model Content
[0003] To address the shortcomings of existing technologies, this application provides a layered water intake cable protection device, which aims to protect the cables in the layered water intake system by creating a still water zone, thereby preventing the cables from being damaged by water flow.

[0005] Preferably, the cable isolation mechanism includes a cable tray cover; the cable tray cover is connected to the cable protection frame and is located between the cable protection frame and the cable tray, so that the cable is housed in the still water space formed by the cable tray cover and the cable protection frame.
[0006] Preferably, the cable tray cover is further provided with several cable distribution trays; the cable distribution trays are located between the cable protection frame and the cable tray cover, so that the cables inside the cable tray cover can be distributed and stored in each cable distribution tray.

[0008] Preferably, the cable protection frame includes several independent cable protection frames, each of which has a beam structure that runs through the doorway.
[0009] Preferably, the cable protection frame is equipped with a slider, which contacts the door slot when the stratified water intake cable protection device is assembled in the door slot.
[0010] Preferably, the cable protection frame is equipped with hanging lugs.
[0011] Compared with the prior art, this application has the following beneficial effects:

[0038] Example
[0039] like Figure 1-6 As shown, this embodiment provides a stratified water intake cable protection device, which, when installed in a stratified water intake system, can protect the cable. The stratified water intake system includes a gate slot 2, a guide vane valve is placed in the gate slot 2, and a power transmission cable 3 is connected to it. Depending on the draft, the guide vane valve includes a lower first guide vane valve 41 and an upper second guide vane valve 42.
[0040] The layered water intake cable protection device provided in this embodiment includes a cable protection frame 1 and a cable isolation mechanism. The cable protection frame 1 is installed in the door slot 2 of the water intake structure. The cable isolation mechanism is connected to the cable protection frame 1 and can isolate and form a still water area for accommodating the cable 3. By isolating the cable 3 from the flowing water area, the cable 3 is protected from damage.
[0041] In this embodiment, the cable protection frame 1 is positioned above the guide vane valve, providing protection for the portion of the cable 3 located between the top of the guide vane valve and the horizontal plane. Furthermore, the cable protection frame 1 includes several independent cable protection frames, which can be flexibly selected according to different horizontal plane heights. Each independent cable protection frame is equipped with a crossbeam structure traversing the door slot 2, and the overall shape is either U-shaped or other shapes, giving the independent cable protection frame good structural stability. In this embodiment, the cable protection frame 1 includes a lower-positioned first cable protection frame 11 and an upper-positioned second cable protection frame 12.
[0042] Regarding the specific structure of the cable isolation mechanism, such as Figure 1-6 As shown, the cable isolation mechanism of this embodiment includes a cable tray cover 71, which is connected to the cable protection frame 1 and located between the cable protection frame 1 and the door slot 2. This allows the cable 3 to be stored in the still water space formed by the cable tray cover 71 and the cable protection frame 1, thereby preventing damage from water flow. At the same time, the cable 3 is completely or partially covered to ensure external aesthetics.
[0043] Furthermore, in this embodiment, the cable tray cover 71 is also provided with a plurality of cable distribution trays 72. The cable distribution trays 72 are connected to the cable protection frame 1 and are located between the cable protection frame 1 and the cable tray cover 71, so that the cables 3 inside the cable tray cover 71 can be distributed and stored in each cable distribution tray 72, thereby enhancing the protection effect of the cables 3 and further playing a better limiting role for the cables 3.
[0044] In another implementation, such as Figure 7-10As shown, the cable isolation mechanism is a water-blocking baffle 8. When the layered water intake cable protection device is installed in the gate slot 2, the water-blocking baffle 8 can partially or semi-close the gate slot 2 to form a cavity structure. The cable 3 is housed in the cavity structure formed by the water-blocking baffle 8 and the gate slot 2, thereby avoiding damage by water flow. At the same time, the cable 3 is fully or partially covered to ensure external aesthetics.
[0045] The cable protection frame 1 is equipped with hooks 5, which makes it easier for external equipment to grab the cable protection frame 1, thus making it more convenient to pull the protection frame out or put it in the door slot 2. In this embodiment, the first cable protection frame 11 and the second cable protection frame 12 are each independently provided with several hooks 5, which are distributed on the crossbeam, thereby making the operation of the protection frame more stable and reliable.
[0046] The cable protection frame 1 is equipped with a slider 6. When the layered water intake cable protection device is assembled in the gate slot 2, the slider 6 contacts the gate slot 2, thereby limiting the cable protection frame 1. Furthermore, in this embodiment, the slider 6 is also divided into a main slider 61 and a secondary slider 62, which respectively contact the opposite wall of the gate slot 2 on one side to increase stability. Different protrusion heights can also be set for different sliders according to actual structural requirements.
[0047] The layered water intake cable protection device provided in this embodiment has outstanding technical effects. First, this embodiment can create a still water isolation space through the cable isolation mechanism, physically isolating the cable from the external flowing, high-impact water area. This significantly reduces the direct scouring, impact, and pulling wear of the cable by the water flow, effectively preventing physical damage to the cable due to hydraulic forces. It can also cover the cable, making the external appearance neater and improving the overall aesthetics of the equipment. Second, the device in this embodiment can use independently set up several cable racks, and the protection height can be flexibly configured according to different water levels or drafts, making it highly adaptable and meeting the needs of water intake facilities of different sizes. Third, this embodiment can further install cable tray covers and cable distribution trays to further separate and store the internal cables, preventing wear and interference caused by multiple cables rubbing and tangling together inside the enclosure.
[0048] The specific embodiments of this application have been described above. Based on the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this application.
