Description

Technical Field

[0001] The present invention relates to the technical field of fireproof windows, and in particular to a fireproof door and window for security. Background Art

[0002] When a fire occurs during the day, people can quickly detect the occurrence of a fire through vision, feeling, smell, etc., and escape from the fire scene in time. However, if a fire occurs in the early morning, residents are in deep sleep and it is difficult to detect the occurrence of a fire in time. Usually, when the fire becomes more and more serious, residents perceive changes in the external environment and realize that a fire has occurred. At this time, the best escape opportunity has been missed, which leads to casualties among residents.

[0003] When a fire occurs, fireproof windows will not be deformed by heat within a certain period of time, ensuring that people can escape through the fireproof windows. Fireproof windows can slow the spread of fire and limit the fire to a certain range, which can buy more escape time for people and avoid losses caused by fire.

[0004] However, existing fireproof doors and windows for security are usually made of special materials, which are costly and can only prevent the spread of fire but cannot block the heat to relieve and cool down autonomously. They are prone to become hot after a fire and are difficult to open, and they do not serve the purpose of warning residents. Summary of the invention

[0005] In order to solve the above technical problems, the present invention designs a fireproof door and window for security.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Example: Figure 1-Figure 3 As shown, a fireproof door and window for security, comprising a door and window frame 1 and a window body rotatably connected to the door and window frame, the window comprising an outer window frame 2 and a double-layer glass 3 in the middle, the middle interlayer of the double-layer glass forms a water curtain channel, a water storage tank 4 and a water collecting tank 5 are respectively provided at the upper and lower ends of the water curtain channel between the double-layer glass, a water inlet hole is provided at the top of the water storage tank, a water outlet hole is provided at the bottom of the water collecting tank, a water inlet pipe 11 is connected to the water inlet hole, the water inlet pipe passes through the upper end transition part between the door and window frame and the window body to connect to a water supply pipeline, a water outlet pipe 15 is fixedly connected to the bottom of the water outlet hole, a drain pipe 16 is provided on the outer sleeve of the water outlet pipe, and the drain pipe passes through the lower end transition part between the door and window frame and the window body to connect to a return water pipeline; The upper end transition part and the lower end transition part respectively include a hollow screw 12 and a locking nut 13, one end of the hollow screw passes through the door and window frame and the window outer frame, and connects the door and window frame and the window body through the locking nut, so that the door and window frame and the window body are rotatably connected, and the water inlet pipe and the drain pipe are respectively connected through the central through hole of the hollow screw; A temperature sensor 9 is installed on the window outer frame, an electric control regulating valve is installed on the water inlet pipe, and the temperature sensor and the electric control regulating valve are connected to a controller. The controller is controlled by PLC.

[0019] When a fire occurs around doors and windows, the temperature sensor senses that the temperature exceeds the specified range and feeds back to the controller. The controller controls the electronically controlled regulating valve to adjust the water inlet. A water curtain is formed in the water curtain channel to cool the doors and windows, preventing them from becoming hot and difficult to open, thereby slowing the spread of the fire.

[0020] A damping sheet 14 is sleeved between the hollow screw and the locking nut on the hollow screw. By setting the damping sheet and adjusting the locking nut, damping can be achieved when the window rotates, so that the window rotates too flexibly or cannot be rotated.

[0021] A row of water curtain nozzles 6 are evenly arranged at the entrance of the water curtain channel at the bottom of the water storage tank. Balanced water spraying forms a water curtain, making the water curtain more evenly formed.

[0022] An upper limit liquid level sensor 7 and a lower limit liquid level sensor 8 are respectively arranged at the upper and lower parts of the water storage tank, and the upper limit liquid level sensor and the lower limit liquid level sensor are respectively connected to the controller.

[0023] The upper limit liquid level sensor and the lower limit liquid level sensor feedback controller are used to adjust the electronically controlled regulating valve so that the water level is always maintained between the upper limit liquid level sensor and the lower limit liquid level sensor to ensure the balance of the water curtain.

[0024] The upper and lower transition parts are installed in the center of the door and window frames and the window body respectively. The double-layer glass is made of fire-resistant heat-conducting glass, and the door and window frames and window outer frames are made of stainless steel. The connection between the double-layer glass and the window outer frame is waterproof and sealed.

[0025] The controller is connected to an alarm. The alarm is equipped with light warning and sound control warning, which warns residents to escape through light and sound.

[0026] Window handles 10 are respectively arranged on both sides of the window outer frame. The water inlet pipe, the water outlet pipe and the drain pipe respectively adopt high temperature resistant soft rubber tubes.

[0027] When the fireproof doors and windows for security are in use, the fire alarm feedback temperature of the temperature sensor is set. When the door and window accessories catch fire, the temperature sensor senses that the temperature exceeds the specified range and feeds back to the controller. The controller controls the electric control valve to adjust the water inlet, and a water curtain is formed in the water curtain channel to cool down, so as to prevent the doors and windows from becoming hot and difficult to open, thereby delaying the spread of the fire.

[0028] At the same time, the controller feeds back to the alarm. The alarm is equipped with light warning and sound control warning, which warns residents to escape through light and sound.

[0029] Normally, when the weather is hot, the security doors and windows of the present invention can also be controlled by the controller to actively form a water curtain, which also has the effect of cooling down and relieving the heat in overheated weather.

[0030] The above-described embodiment is only a preferred solution of the present invention and does not limit the present invention in any form. There are other variations and modifications without exceeding the technical solution described in the claims.
