Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fireproof cover plates, and specifically discloses a fireproof cover plate for a cable trench. Background Art
[0002] In order to facilitate personnel to check the condition of the cables inside the cable trench, the fireproof cover of the cable trench will be connected to the frame in a hinged manner. When personnel are inspecting the cables, they can open the cover manually without using tools. Since there is a gap between the cover body and the frame, rainwater will gather in the gap. The sealing strip will be soaked in rainwater for a long time and will be eroded by rainwater, which will accelerate the oxidation rate of the sealing strip and result in lower sealing performance of the fireproof cover. Utility Model Content
[0003] In view of the above-mentioned defects or shortcomings in the prior art, the present application aims to provide a fireproof cover for a cable trench, comprising a frame, a cover body rotatably connected to the inner side of the frame by bolts, a avoidance groove arranged on the top of the cover body and a locking mechanism installed on the inner side of the avoidance groove, and a sealing strip sleeved on the inner side of the frame and located below the cover body, a drainage groove located on the outside of the sealing strip is provided inside the frame, and a first drainage outlet connected to the drainage groove is provided on both sides of the frame.
[0004] Preferably, a second drain outlet is provided inside the cover plate body and is connected to the avoidance groove and is located above the drain groove.
[0005] Preferably, the locking mechanism includes a limiting rod movably sleeved inside the frame and the cover body and located on the inner side of the avoidance groove, a spring sleeved inside the cover body is placed on one side of the limiting rod, a fixing pin is sleeved on the inner side of the limiting rod, and a handle is fixedly sleeved inside the limiting rod through the fixing pin.
[0006] Preferably, the limiting rod is arranged directly above the second drain outlet.
[0007] Beneficial effects:
[0008] 1. The fireproof cover of the cable trench can collect rainwater that penetrates into the gap between the frame and the cover body through the drainage groove, and at the same time, the water in the drainage groove can be discharged to the outside of the frame through the first drainage port, thereby preventing the sealing strip from being soaked by rainwater and causing erosion, reducing the oxidation rate of the sealing strip, and enhancing the sealing performance of the fireproof cover.
[0009] 2. The fireproof cover of the cable trench has a spring installed inside the cover body so that the spring will not come into direct contact with rainwater, and the rainwater accumulated in the avoidance groove can be discharged into the drainage groove for collection through the second drainage port, thereby preventing the rainwater from eroding the locking mechanism.

[0017] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.
[0018] The accompanying drawings in the embodiments of the present invention: different types of section lines in the drawings are not marked according to national standards, nor do they impose any requirements on the materials of the components. Instead, they are used to distinguish the cross-sectional views of the components in the drawings.
[0019] See also Figure 1-5 A fireproof cover plate for a cable trench comprises a frame 1, a cover plate body 3 rotatably connected to the inner side of the frame 1 by bolts 2, a avoidance groove 4 arranged on the top of the cover plate body 3 and a locking mechanism 5 installed on the inner side of the avoidance groove 4, and a sealing strip 6 sleeved on the inner side of the frame 1 and located below the cover plate body 3. A drainage groove 7 located on the outer side of the sealing strip 6 is provided inside the frame 1. Rainwater infiltrating into the gap between the frame 1 and the cover plate body 3 can be collected through the drainage groove 7 to prevent the sealing strip 6 from being soaked by rainwater. First drainage ports 8 connected to the drainage groove 7 are provided on both sides of the frame 1. The rainwater collected in the drainage groove 7 can be discharged to the outside of the frame 1 through the first drainage port 8 to prevent excessive rainwater from gathering inside the drainage groove 7.
[0020] Among them, a second drain port 9 is opened inside the cover body 3, which is connected with the avoidance groove 4 and located above the drain groove 7. The water accumulated inside the avoidance groove 4 can be discharged into the drain groove 7 through the second drain port 9, avoiding rainwater from accumulating inside the avoidance groove 4, so that the locking mechanism 5 is not easily corroded by rainwater.
[0021] Among them, the locking mechanism 5 includes a limit rod 51 which is movably sleeved inside the frame 1 and the cover body 3 and is located on the inner side of the avoidance groove 4. A spring 52 sleeved inside the cover body 3 is placed on one side of the limit rod 51. The elastic force of the spring 52 enables the limit rod 51 to be stably inserted into the interior of the frame 1, and then the cover body 3 can be limited and fixed by the limit rod 51. A fixing pin 53 is sleeved on the inner side of the limit rod 51, and a handle 54 is fixedly sleeved inside the limit rod 51 through the fixing pin 53. The limit rod 51 can be rotated by the handle 54 and the limit rod 51 can be pulled by the handle 54, so that the limit of the cover body 3 by the limit rod 51 can be released. At this time, the cover body 3 can be driven to rotate around the axial direction of the bolt 2 by pulling the handle 54, so that the cover body 3 can be opened.
[0022] Among them, the limiting rod 51 is arranged just above the second drain outlet 9. By setting the limiting rod 51 just above the second drain outlet 9, the limiting rod 51 can partially block the second drain outlet 9 to prevent debris from falling into the inside of the avoidance groove 4 and clogging the second drain outlet 9, thereby ensuring that rainwater inside the avoidance groove 4 can be discharged into the interior of the drainage groove 7 through the second drain outlet 9.
[0023] When inspecting the cable, the limit rod 51 is rotated by the handle 54, and the handle 54 is rotated to the outside of the avoidance groove 4. The limit rod 51 is pulled by the handle 54, so that the limit rod 51 compresses the spring 52 and at the same time releases the limit of the cover body 3 by the limit rod 51. At this time, by continuing to pull the handle 54, the cover body 3 can be driven to rotate around the axial direction of the bolt 2, and then the cover body 3 is opened. The contents not described in detail in this description belong to the existing technology known to professional and technical personnel in this field.
