In the dismounting and replacing process, the rotating rod 7 plays a role of rotating connection, provides a rotating support point for the rotating plate 8, and enables the rotating plate 8 to rotate outward around the rotating rod 7, so as to open the guide groove 15 and create conditions for taking out the roller shutter fire door 14.
[0036] Referring to Figure 1 , Figure 2 and Figure 4The sealing mechanism comprises a plurality of spring twos 17, a plurality of square grooves 16 are formed on the left and right sides of the interior of the fire hydrant box 1 respectively, the rear sides of the two spring twos 17 are fixedly connected to the rear inner walls of the square grooves 16, the front sides of the two spring twos 17 are fixedly connected with arc-shaped plates 18, the outer walls of the arc-shaped plates 18 are slidingly connected to the inner walls of the square grooves 16, and the square grooves 16 provide mounting spaces for the spring twos 17 and the arc-shaped plates 18. The front sides of the plurality of arc-shaped plates 18 are in contact with the rear side of the roller shutter fireproof door 14, the interior of the fire hydrant box 1 is provided with a guide groove 15, the exterior of the roller shutter fireproof door 14 is slidingly connected to the inner wall of the guide groove 15, when the roller shutter fireproof door 14 slides downward to be closed, the arc-shaped plate 18 pressed by the roller shutter fireproof door 14 transmits the pressure to the spring two 17, and at the same time, under the reaction force of the spring two 17, the arc-shaped plate 18 exerts outward extrusion force on the roller shutter fireproof door 14, which helps to improve the sealing effect. The guide groove 15 provides accurate guidance for the lifting of the roller shutter fireproof door 14, ensures that the roller shutter fireproof door 14 will not deviate during the movement process, and guarantees that the roller shutter fireproof door 14 can be accurately closed and opened, and at the same time, cooperates with the sealing mechanism to improve the sealing performance. The front inner wall of the guide groove 15 is fixedly connected with a sealing strip 19, and the rear side of the sealing strip 19 is in contact with the front side of the roller shutter fireproof door 14. When the roller shutter fireproof door 14 is closed, under the action of the spring two 17, the roller shutter fireproof door 14 is tightly attached to the sealing strip 19, and the sealing strip 19 can effectively prevent the invasion of smoke and fire, thereby improving the sealing performance of the fire hydrant box 1.
[0037] Working principle: when the roller shutter fireproof door 14 is used for a long time or damaged due to external factors, the power generated by starting the air cylinder 5 drives the rotating block 6 to move upward, cooperates with the action of the fixed rod 3 and the support of the rotating seat 4 to make the bottom of the rotating block 6 can rotate around the fixed rod 3, and at the same time, the rotating block 6 can rotate at the bottom of the T-shaped sliding block 10, realizes that the upward movement of the rotating block 6 drives the T-shaped sliding block 10 to slide in the T-shaped sliding groove 9, and cooperates with the rotating connection of the rotating rod 7 to drive the rotating plate 8 to rotate outward around the rotating rod 7, so as to achieve the opening of the guide groove 15, so that the roller shutter fireproof door 14 can be taken out, which is convenient for replacing the roller shutter fireproof door 14;
[0038] When the roller shutter fireproof door 14 slides downward along the guide groove 15, it will contact and press the arc-shaped plate 18, and at the same time, compress the spring two 17, after the roller shutter fireproof door 14 completely closes the fire hydrant box 1, the compressed spring two 17 generates pressure to extrude the roller shutter fireproof door 14 outward, so that the roller shutter fireproof door 14 is tightly attached to the sealing strip 19, thereby increasing the sealing performance of the roller shutter fireproof door 14 to the fire hydrant box 1.
[0039] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
