The door leaf and handle of the fire door are easy to conduct heat in the case of indoor fire. When people in the room escape, they may be burned by the door leaf or door handle of the steel fire door. Utility Model Content
[0003] The purpose of the utility model is to provide a steel fireproof door in view of the above-mentioned technical problems, wherein a cooling component can cool the door leaf to prevent the escapees from being scalded during the escape process.
[0004] In view of this, the utility model provides a steel fire door, including a frame, a door leaf connected to a hinge inside the frame, the top of the door leaf is connected to the same side of the frame through a door closer, and also includes a cooling component, the cooling component includes a liquid flow cavity arranged at the upper end of the frame, the liquid flow cavity pipeline is connected to a water tank, and a liquid collecting cavity is arranged at the bottom of the door leaf corresponding to the liquid flow cavity.
[0005] In this technical solution, the door closer (not shown) is arranged at Figure 1 On the back side (that is, the fire door is arranged on the side facing the corridor at the entrance of the corridor), the liquid flow chamber is arranged in the top frame on the side of the door leaf facing the indoor room. When a fire occurs indoors, the water tank in the cooling component supplies water to the liquid flow chamber. The water flowing through the liquid flow chamber flows downward along the surface of the door leaf, cooling the door leaf and the handles on the door leaf, so as to prevent indoor personnel from being scalded by the door leaf and the handles due to the heat transferred by the fire source when escaping. A liquid collecting chamber is arranged on the bottom wall of the door leaf corresponding to the liquid flow chamber. The liquid collecting chamber is buried underground to receive water falling from above, so as to prevent a large amount of water from flowing on the ground and causing the escapees to slip during the hasty escape.
[0006] In the above technical solution, further, the liquid flow chamber includes a hollow shell, the shell extends along the width direction of the door leaf, a liquid outlet is provided at the bottom of the shell against the bottom of one side of the door leaf, the liquid flow chamber is connected to the water tank through a first pipe, and a first pump body is arranged on the first pipe.
[0007] In the above technical solution, further, the liquid outlet is a strip-shaped opening extending along the width direction of the door leaf.
[0008] In the present technical solution, when a fire occurs indoors, the first pump body draws water from the water tank into the liquid flow chamber. The liquid flow chamber is arranged along the width direction of the door leaf. In the embodiment, there are two door leaves. The liquid flow chamber is arranged in a frame directly above the two door leaves. The liquid outlet is a strip opening and is opened against one side of the door leaf, ensuring that the water flowing out of the liquid flow chamber can flow downward along the door leaf to fully cool the door leaf and the handle.
[0009] In the above technical solution, further, a partition plate is arranged in the liquid flow chamber, and the partition plate is arranged along the length direction of the liquid flow chamber, and both ends are connected to the inner wall of the liquid flow chamber. The side of the partition plate away from the liquid outlet and the inner wall of the liquid flow chamber form a uniform flow groove, and one end of the uniform flow groove is connected to the first pipeline.
[0010] In the present technical solution, through the setting of the partition plate, the water entering the liquid flow cavity through the first pipe first fills the uniform flow groove, and the water from the first pipe continues to enter, the water overflows from the liquid flow cavity, and leaves the liquid flow cavity from the liquid outlet. The setting of the uniform flow groove ensures that the water flows out from the narrow and long liquid outlet more evenly, and also ensures the continuity of the liquid outlet.
[0011] In the above technical solution, further, the liquid collecting chamber includes a box body, a liquid collecting trough is arranged in the box body, the bottom wall of the liquid collecting trough is connected to a liquid discharge port, a receiving interface is arranged at the top of the liquid collecting trough corresponding to the liquid outlet, a closing component is arranged at the receiving interface, and the closing component can cover the receiving interface.
[0012] In the technical solution, when there is no fire, the closing component shields the receiving interface to prevent dust and garbage from clogging the drain port.
[0013] In the above technical solution, further, the closing component includes a baffle plate, which is connected to a first rotating rod through a connecting column, the first rotating rod is rotatably arranged on both sides of the liquid collecting tank, one side of the first rotating rod passes through the liquid collecting chamber and is rotatably connected to the fixed block, the first rotating rod passes through the liquid collecting chamber and is coaxially fixedly connected to the first turbine, the first turbine is meshingly connected to the first worm, and the first worm and the first motor are transmission connected.
[0014] In the present technical solution, one side of the first worm gear is connected to the first motor, and the other side is rotatably connected to the support block. In the present embodiment, the liquid collecting tank is a tank with a circular cross-section, and the baffle plate is against the inner wall of the liquid collecting tank. The baffle plate is a corresponding arc-shaped plate, which is connected to the first rotation through a number of connecting columns. When there is no fire in normal times, the turbine worm gear is self-locked to ensure that the receiving interface at the top of the liquid collecting tank is fully blocked by the baffle plate to prevent debris from entering the liquid collecting tank and blocking the drain port. When a fire occurs, the baffle plate rotates under the drive of the first rotating rod, and the receiving interface is not blocked by the baffle plate. The receiving interface can receive water flowing down from the upper liquid flow cavity to cool the door leaf and handle.
[0015] In the above technical solution, further, the discharge port is connected to a second pipe, the second pipe is connected to a cooling box, the cooling box and the water storage tank are connected through a third pipe, a second pump body is arranged on the second pipe, and a third pump body is arranged on the third pipe.
[0016] In the present technical solution, the cooling box is a common heat exchange device, which can perform heat exchange and cooling on the water flowing through the cooling box. It is a prior art, so the specific internal structure of the cooling box will not be elaborated. Through the arrangement of the cooling box, the second pipe, the second pump body, the third pipe and the third pump body, the water used to cool the door leaf can be recycled.
[0017] In the above technical solution, further, a smoke sensor and a temperature sensor are arranged on one side of the frame, and the smoke sensor, the temperature sensor and the external control center are electrically connected.
[0018] In the present technical solution, when the smoke sensor senses smoke of sufficient concentration, and the temperature sensor senses a temperature rise that is significantly above the normal value, feedback is given to the external control center, and the first motor and the pump body start working to cool the door leaf. The smoke sensor and the temperature sensor are both existing technologies, so they will not be elaborated.
[0019] The beneficial effects of the utility model are:
[0020] 1. The water tank supplies water to the liquid flow cavity. The water flowing through the liquid flow cavity flows downward along the surface of the door leaf, cooling the door leaf and the handle on the door leaf, preventing the indoor personnel from being scalded by the door leaf and the handle when escaping from the fire source. A liquid collecting cavity is provided on the bottom wall of the door leaf corresponding to the liquid flow cavity. The liquid collecting cavity is buried underground to receive the water falling from above, preventing a large amount of water from flowing on the ground and causing the escapees to slip in a hurry;
[0021] 2. A partition plate is arranged in the liquid flow cavity. The water entering the liquid flow cavity from the first pipe first fills the uniform flow groove. The water from the first pipe continues to enter, and the water overflows from the liquid flow cavity and leaves the liquid flow cavity from the liquid outlet.
