Description

Technical Field

[0001] This utility model relates to the field of fire protection, and in particular to a fire-resistant partition roller shutter door. Background Technology

[0002] Fire prevention refers to the prevention of fires or the reduction of losses caused by fires through a series of prevention, control and extinguishing measures. Fire prevention is an important link in protecting people's lives and property, covering multiple aspects such as building design, construction, equipment configuration and emergency management. Fireproof partition roller shutters are a common type of fire prevention equipment.

[0003] Chinese Patent Publication No. CN221400314U discloses a fire-resistant auxiliary roller shutter door, including a housing body. The bottom of the housing body is provided with a connecting frame, and the housing body extends into the interior of the connecting frame to provide a roller shutter. Inside the connecting frame and below the roller shutter, there are two sets of sleeves. A buffer rod is slidably connected inside the sleeve, and a movable plate is provided inside the buffer rod extending into the sleeve. However, the existing device still has some shortcomings. When the existing device is in use, if a fire occurs and the fire-resistant roller shutter door is closed, the power needs to be disconnected, which will prevent the roller shutter door from rising again, making it impossible for the remaining personnel to escape or carry out fire-fighting operations through the fire-resistant roller shutter door. Therefore, we propose a fire-resistant partition roller shutter door to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a fire-resistant partition roller shutter door to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fire-resistant partition roller shutter door includes an installation frame. A top frame is fixedly connected to the upper surface of the installation frame. Two bearings are fixedly embedded in the inner wall of the top frame. The inner rings of the two bearings are fixedly connected to a connecting rod. A drive motor is installed at the right end of the connecting rod. A roller shutter door body is fitted onto the outer surface of the connecting rod. A base plate is installed on the bottom surface of the roller shutter door body. Limit blocks are fixedly connected to both ends of the base plate. A storage groove is formed on the inner side wall of the installation frame. A movable frame is slidably connected inside the storage groove. Two electric push rods are installed on the left side of the installation frame. The output ends of the two electric push rods are fixedly connected to the left side of the movable frame. A protective door is installed on the outer surface of the movable frame. A fixing plate is fixedly connected to the right side of the movable frame. Limit grooves are formed on the right side of the fixing plate, the inner side wall of the installation frame, and the inner side wall of the top frame. Each limit block is slidably connected to the limit groove.

[0007] In a further embodiment, alarm lights are installed on both the front and back of the top frame, and handles are fixedly connected to both the front and back of the protective door.

[0008] In a further embodiment, a protective frame is fixedly connected to the front of the mounting frame, and a control panel is installed inside the protective frame.

[0009] In a further embodiment, two sliding grooves are provided on the inner top wall and the inner bottom wall of the storage groove, and two sliding plates are fixedly connected to the upper surface and the bottom surface of the moving frame, with each sliding groove being adapted to a sliding plate.

[0010] In a further embodiment, a maintenance plate is installed on the front of the top frame, and the maintenance plate has a heat dissipation window on its front.

[0011] In a further embodiment, a plurality of mounting plates are fixedly connected to the upper surface of the top frame, and each mounting plate has a fixing hole on its upper surface.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model discloses a fireproof and fire-resistant roller shutter door. A drive motor within the device drives a connecting rod to raise and lower the roller shutter door body, thereby isolating a large fire. During the isolation process, two electric push rods push a moving frame, allowing both the protective door and the roller shutter door body to work together for fire protection. Furthermore, the protective door can be opened after a power outage, facilitating passage for escaping personnel or rescue workers. Therefore, this device effectively solves the problem of existing devices requiring power disconnection, which prevents the roller shutter door from rising again, thus hindering escape or firefighting operations.

[0025] The working principle of this utility model is as follows:

[0026] When using this fire-resistant partition roller shutter door, the staff first assembles the device and installs it in a suitable position. Then, they inspect all the components of the device to ensure its normal operation. Next, in the event of a fire, the two electric push rods 16 in the device are activated through the control panel 8, causing the electric push rods 16 to push the moving frame 12 to move. After moving to a suitable position, the drive motor 23 in the device is activated, which drives the connecting rod 21 to rotate, causing the roller shutter door body 10 to move downward. During the movement, the stability of the roller shutter door body 10 is ensured by the cooperation of two limit blocks 22 and multiple limit grooves 4. Finally, by opening the protective door 14 in the moving frame 12, it is possible for escapers or rescuers to pass through.
