Description

Technical Field

[0001] The utility model relates to the technical field of fire protection, in particular to an anti-blocking outdoor fire hydrant. Background Technique

[0002] A fire hydrant is a fixed fire protection facility. Its main functions are to control combustibles, isolate combustion-supporting substances, and eliminate ignition sources. It is divided into indoor fire hydrants and outdoor fire hydrants. Fire hydrants are mainly used for fire trucks to draw water from the municipal water supply network or the outdoor fire water supply network to implement fire extinguishing, and can also be directly connected to a water hose and a water gun to discharge water for fire extinguishing. For example, the patent with the publication number CN218911615U discloses an anti-blocking outdoor fire hydrant, which includes a fire hydrant main body. First clamping grooves are respectively formed in the circumferences of the inner ring surfaces of the first connecting pipes at the ends far away from the fire hydrant main body. Matching first clamping blocks are arranged in the first clamping grooves. The first clamping blocks located inside the first connecting pipes are jointly fixed with a first fixing ring. A plurality of first baffles in an inclined state are fixed on the inner ring surface of the first fixing ring. Second clamping grooves are respectively formed in the circumferences of the inner ring surfaces of the second connecting pipes at the ends far away from the fire hydrant main body. Matching second clamping blocks are arranged in the second clamping grooves. The second clamping blocks located inside the second connecting pipes are jointly fixed with a second fixing ring. A plurality of second baffles in an inclined state are fixed on the inner ring surface of the second fixing ring. During the use process, it is convenient to protect the interior of the fire hydrant, can avoid blockage inside the fire hydrant, and helps to keep the normal use of the fire hydrant. However, after connecting the water pipe, the baffles will block the water flow, thus affecting the water pressure and resulting in a slow water supply speed.

[0011] Further, a second spring is fixed between the second groove and the pressing block.

[0012] Further, the fire hydrant body further includes a valve rod and a sealing plug.

[0013] The beneficial effects of the present utility model: An anti-blocking outdoor fire hydrant of the present utility model includes a connection port; an anti-blocking structure; a limiting structure.

[0014] By installing the anti-blocking structure inside the connection port, the anti-blocking structure can be rotated, thereby reducing the influence of the anti-blocking structure on the water flow. By installing the limiting structure inside the connection port, the anti-blocking structure can be limited by the limiting structure, thereby preventing external objects from entering the connection port and preventing the connection port from being blocked. Moreover, the limiting structure can be opened after installing the water pipe, which is convenient for rotating the anti-blocking structure, ensuring the water pressure and improving the strength of the water flow.

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: an anti-blocking outdoor fire hydrant, including a fire hydrant body 1, the fire hydrant body 1 includes a plurality of connection ports 2, an anti-blocking structure is rotatably fitted in the connection port 2, a plug cover 13 is threadedly fitted on the connection port 2, a limiting structure is installed in the connection port 2, the limiting structure includes a first limiting block 6 and a second limiting block 7, the anti-blocking structure is located between the first limiting block 6 and the second limiting block 7, and a pressing block 10 is installed in the connection port 2, and the pressing block 10 corresponds to the plug cover 13 and the first limiting block 6.

[0022] In this embodiment, the limiting structure includes a butterfly plate 3, the butterfly plate 3 corresponds to the connection port 2, a rotating shaft 4 is fixed to the central part of the butterfly plate 3, and the rotating shaft 4 is threadedly fitted with the connection port 2.

[0023] Specifically, when the fire hydrant body 1 is not in use, the butterfly plate 3 can completely block the connection port 2 to prevent objects from entering the connection port 2 and causing it to be blocked. When the fire hydrant body 1 is in use, the rotating shaft 4 can be rotated, so that the rotating shaft 4 drives the butterfly plate 3 to rotate by ninety degrees, thereby driving the connection port 2 to open, and the water flow size can be ensured.

[0024] The second limiting block 7 is fixed in the connection port 2, a first groove 11 is opened in the connection port 2, the first groove 11 corresponds to the first limiting block 6, a first spring 8 is fixed between the first groove 11 and the first limiting block 6, a second groove 12 is opened in the connection port 2, the second groove 12 corresponds to the pressing block 10, and a second spring 9 is fixed between the second groove 12 and the pressing block 10. The fire hydrant body 1 further includes a valve rod 14 and a sealing plug 15, and both the pressing block 10 and the first limiting block 6 are magnets.

[0025] Specifically, when the plug cover 13 is unscrewed, at this time the plug cover 13 no longer presses the pressing block 10, so that the second spring 9 is reset to push the pressing block 10 to move, the pressing block 10 moves away from the first limiting block 6, and thus the force attracting the first limiting block 6 is reduced, so that the first spring 8 pushes the first limiting block 6, thereby limiting the butterfly plate 3 by the first limiting block 6.

[0026] When the water pipe is screwed on, the water pipe can press the pressing block 10, so that the pressing block 10 approaches the first limiting block 6, thereby attracting the first limiting block 6 to reset it. At this time, the first limiting block 6 no longer limits the butterfly plate 3, and the butterfly plate 3 can be rotated.

[0027] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
