[0022] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0023] like Figure 1-6As shown, the utility model provides a fireproof bridge with drainage function, including a fireproof bridge body 1, lower vertical plates 201 are installed on the tops of both sides of the outer surface of the fireproof bridge body 1, the lower vertical plates 201 and the fireproof bridge body 1 are fixedly connected by self-tapping bolts, and the tops of the two lower vertical plates 201 are commonly connected with a cover plate 2, and the cover plate 2 is provided with water eaves 202 extending from both sides of the fireproof bridge body 1, and both sides of the bottom of the fireproof bridge body 1 are provided with concave drainage channels 101, and the outer surface of the fireproof bridge body 1 A lower baffle 102 is provided at the bottom of both sides, and a side wing plate 301 is installed between the inner surface of the lower baffle plate 102 and the outer surface of the fire bridge main body 1, and the bottoms of the two side wing plates extend out from the bottom of the fire bridge main body 1, and a lower connecting plate 3 is commonly connected between the opposite sides of the two side wing plates 301, and a "J"-shaped upper protrusion 302 is provided in the middle of the lower connecting plate 3, and the "J"-shaped upper protrusion 302 is fixedly connected to the bottom of the fire bridge main body 1, and the fire bridge main body 1 and the "J"-shaped upper protrusion 302 are fixedly connected by bolts and nuts.

[0024] The bottom array of the drainage channel 101 is provided with drainage holes 103 , and the drainage holes 103 are used to discharge the liquid inside the fireproof bridge body 1 .

[0025] The surface of the lower connecting plate 3 is provided with drainage grooves 303 in an array between the "X"-shaped upper protrusion 302 and the two side wing plates 301 . The drainage grooves 303 are used to discharge the liquid dropped from the drainage hole 103 .

[0026] The cover plate 2 and the fireproof bridge body 1 located between the two drainage channels 101 are both convex arc-shaped, so that the liquid on the upper surface will slide to both sides, thereby preventing the liquid from accumulating on the surface and causing corrosion.

[0027] Among them, the end of the eaves 202 away from the cover plate 2 is tilted downward, so that rainwater can slide down from both sides of the cover plate 2 more conveniently.

[0028] Among them, inward-folded inner support plates 104 are provided on the top of both sides of the inner surface of the fireproof bridge frame body 1, and the inner support plates 104 are used to increase the contact area between the cover plate 2 and the fireproof bridge frame body 1, thereby improving the connection strength between the fireproof bridge frame body 1 and the cover plate 2.

[0029] Specific working principle:

[0030] When the utility model is in use, the cables are installed inside the fireproof bridge of the utility model, and the cables are supported and protected by the fireproof bridge body 1, which is convenient for cable management. During the use of the utility model, the opening on the top of the fireproof bridge body 1 is closed by the set cover plate 2, thereby reducing the probability of water entering the inside of the fireproof bridge body 1. At the same time, the cover plate 2 is an upward convex arc, which can effectively prevent water from accumulating on the top of the cover plate 2 and causing corrosion of the cover plate 2. The set water eaves 202 can effectively prevent water sliding down from the cover plate 2 from contacting the surface of the fireproof bridge body 1, thereby further reducing the probability of water entering the fireproof bridge body 1. At the same time, for some water droplets blown to the surface of the fireproof bridge body 1, the lower baffle 102 can be used to guide the water flow to the surface of the side wing plate 301. Since the bottom of the side wing plate 301 is from the bottom of the fireproof bridge 1, and the drain holes 103 are used as the drain holes 103 of the fireproof bridge frame body 1 to prevent the water from entering the fireproof bridge frame body 1.
