[0023] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0024] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0025] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment are included in at least one embodiment of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments in a suitable manner.

[0026] like Figure 1-5 As shown, in this embodiment, the lightning protection grounding point protection device for a building comprises an external box body 1 arranged in cooperation with the lightning protection grounding point opening, the external box body 1 comprises an outer frame body 11, the inner and outer sides of the outer frame body 11 are respectively provided with an inner opening 12 and an outer opening 13, an opening and closing cover 14 is installed at the outer opening 13, and a water guide 2 is connected to the inner opening 12;

[0027] The water guide member 2 includes an n-shaped slot plate 21 extending from the top of the inner opening to both sides, the slot of the n-shaped slot plate is arranged toward the outer frame, the outer top of the n-shaped slot plate 21 is connected with a first fixing portion 22 along the slotting direction, so that it extends to the outside of the second fixing portion 15 provided at the inner opening 12 and is connected thereto, the top of the n-shaped slot plate 21 is connected with an abutting portion 23 extending inwardly in a vertical slotting direction, so that it can be inserted into the lightning protection grounding point opening 3 and abut against the inner wall side of the lightning protection grounding point opening, the bottom of the first fixing portion 22 is arranged higher than the slot, and the outer opening 13 is larger than the water guide member 2, so that the water guide member 2 can enter the inner opening 12 from the outer opening 13 and be fixed to the external box body 1; specifically, the external box body 1 and the water guide member 2 can be fixed to the building wall outside the lightning protection grounding point opening by expansion bolts 4;

[0028] A sealing plate 24 is respectively disposed at both ends of the n-shaped groove plate 21 . The sealing plate 24 is arranged to be inclined downward from the inside to the outside. A drain port 16 is disposed at the bottom of the outer frame 11 .

[0029] When installing the above protective devices, refer to Figure 2Since the water guide 2 is smaller than the outer opening, the water guide 2 can enter the outer frame 11 from the outer opening 13. Figure 5 Since the bottom of the second fixing portion 15 at the inner opening is higher than the notch of the n-shaped slot plate 21, the first fixing portion 22 can pass through the inner opening, and the first fixing portion 22 will be attached to the outside of the second fixing portion 15 and fixed thereto, so that the fixing is more convenient, and when rainwater seeps into the gap between the upper part of the external box body 1 and the wall, the rainwater will first enter the groove of the n-shaped slot plate and flow downward along the groove (see Figure 1 or Figure 3 ), due to the presence of the sealing plate, part of its side surface abuts against the inner wall of the grounding point, so the water will flow through the first fixing portion 22 and the wall gap to the bottom of the outer frame 11, and then flow out from the drain port 16. The presence of the water guide 2 can effectively prevent rainwater from entering the grounding point, reduce the corrosion rate of the flat iron, and extend its service life.

[0030] Among them, regarding the installation of the opening and closing cover 14, one side of it can be rotatably connected to the outer frame 11 through a hinge shaft to realize the side opening setting of the opening and closing cover 14. In addition, the opening and closing cover 14 and the outer frame 11 are tightly fitted. Therefore, in order to facilitate opening the opening and closing cover during testing, an opening portion is set on the open side of the opening and closing cover.

[0031] In one specific embodiment, the water guide speed can be adjusted by setting a gasket between the second fixing part 15 and the first fixing part 22. Specifically, after adding the gasket, the gap distance between the first fixing part 22 and the wall will be increased, thereby accelerating the water flow to the bottom of the outer frame 11.

[0032] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.
