Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another.
Example one
With reference to fig. 1 to 3, a fireproof cable trench cover according to an embodiment of the present invention includes: the first cover plate 1 and the second cover plate 2, the first cover plate 1 and the second cover plate 2 need to be matched for use. Specifically, the first cover plate 1 of the present embodiment is a square plate, the first support plates 3 are formed on both sides of the first cover plate 1, the length of the first support plate 3 is the same as that of the first cover plate 1, the thickness of the first support plate 3 is smaller than that of the first cover plate 1, and the first support plate 3 is flush with the end surface of the first cover plate 1 facing the cable trench. A diversion trench 4 is formed in the end face, away from the cable trench, of the first supporting plate 3, the diversion trench 4 is arranged along the length direction of the first supporting plate 3, and the diversion trench 4 penetrates through the length direction of the first supporting plate 3. That is to say, when the first cover plate 1 covers the cable trench, the guiding gutter 4 can guide the liquid to both sides of the cable trench to be discharged, and the liquid is prevented from entering the cable trench. It should be noted that the cross-sectional shape of the flow guide groove 4 in this embodiment is rectangular, and of course, the flow guide groove 4 may also have other cross-sectional shapes according to actual needs.
The second cover plate 2 of this embodiment is also a square plate, and the second support plates 5 are formed on both sides of the second cover plate 2, the length of the second support plate 5 is the same as that of the second cover plate 2, the thickness of the second support plate 5 is thinner than that of the second cover plate 2, and the second support plate 5 is flush with the end face of the second cover plate 2 departing from the cable trench. In use, the end face of the second strip 5 facing the trench is operatively abutted against the end face of the first strip 3 facing away from the trench, and the second strip 5 completely covers the channel 4. Then, the second support plate 5 can protect the diversion trench 4, so that stones, garbage and impurities on the road surface can be prevented from falling into the diversion trench 4, and the diversion trench 4 is prevented from being blocked. It is easy to understand that the thickness of the first cover plate 1 is the same as that of the second cover plate 2, and the sum of the thickness of the first support plate 3 and the thickness of the second support plate 5 is the thickness of the cover plate, so that when a plurality of first cover plates 1 and second cover plates 2 are sequentially laid on the cable trench, the flatness of the plate surface can be ensured. It will be readily appreciated that the first and second cover plates 1 and 2 form the first and second brackets 3 and 5 at the mating edges, and therefore, depending on the actual requirements, the first and second cover plates 1 and 2 may be provided with brackets on only one side.
Further, the fire-proof cable trench cover plate of this embodiment further includes an inspection window 6, and an inspection hole is opened on the first cover plate 1, and the inspection window 6 is installed in the inspection hole. Because the quality of the cover plate is heavier, when the cable trough needs to be overhauled, the cover plate is difficult to move by operation and maintenance personnel. And inspection window 6 then can be relaxed by the fortune dimension personnel open, overhaul the cable pit, for example put into the ponding that can take out in the cable pit with the water pipe from inspection window 6.
It is worth noting that the fireproof cable trench cover plate of the embodiment further comprises an annular support plate 7, the annular support plate 7 is arranged along the inner wall of the inspection hole, an annular positioning groove is formed in the annular support plate 7, one end face of the inspection window 6 is abutted to the annular support plate 7, an annular positioning block is formed in one end face of the inspection window 6, and the annular positioning block is operatively embedded in the annular positioning groove. That is, the inspection window 6 is not mechanically fixed to the first cover plate 1, but directly fastened to the ring bracket, thereby facilitating opening and closing. Of course, the inspection window 6 and the first cover plate 1 may be hinged or connected in other ways according to actual needs.
Further, a plurality of flow guide holes 8 are formed in the first cover plate 1, and the flow guide holes 8 are communicated with the flow guide groove 4 and the annular positioning groove. Due to the gap between the inspection window 6 and the annular support plate 7, rainwater or oil of the transformer can also flow into the cable groove, and after the diversion hole 8 is formed, the rainwater or the oil can flow into the diversion groove 4 from the diversion hole 8 and then be discharged.
It is worth noting that the first cover plate 1 and the second cover plate 2 are both made of toughened glass, so that the condition of the whole cable trough can be observed through the glass, and accidents can be conveniently dealt with. And all be provided with anti-skidding line on first apron 1 and the second apron 2, guarantee the safety that the pedestrian passed by.
The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. It should be noted that at least two modifications and refinements may be made by those skilled in the art without departing from the principle of the present application, and these modifications and refinements should also be regarded as the protection scope of the present application.
