Specific implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] like Figures 1 to 7 As shown, this embodiment provides a remote-controlled fire damper, including a valve body frame 1, baffles, a linkage assembly 2, and a reset assembly 3. The valve body frame 1 has open openings 11 on both sides. The valve body frame 1 is divided into upper and lower vents, and the vents are sealed by several baffles and the linkage assembly 2. The baffles are mounted on the mounting bracket 12 inside the valve body frame 1 via shafts. The baffles are divided into upper baffle 4, middle baffle 5, and lower baffle 6. The linkage assembly 2 includes a linkage component 21, a linkage rod 22, and a control shaft 23. The control shaft 23 passes through the mounting bracket 12 and is connected to the middle baffle 5. The linkage component 21 is locked to the upper baffle 4 and the lower baffle 6. The linkage component 21 is hinged to the linkage rod 22.

[0026] Furthermore, a driven gear 73 is installed on the control shaft 23.

[0027] Furthermore, a control box 7 is provided on the outer side of the valve body frame 1, and a motor 71 is installed inside the control box 7. A drive gear 72 is installed at the output end of the motor 71, and the drive gear 72 meshes with the driven gear 73.

[0028] Furthermore, the upper and lower vents are controlled by their respective independent control boxes 7.

[0029] Furthermore, the reset assembly 3 is installed on the opposite side of the valve body frame 1 where the control box 7 is located.

[0030] Furthermore, the reset assembly 3 includes a reset rod 31, a connecting piece 32, a reset spring 33, and a mating piece 34. The reset rod 31 is connected to the lower baffle 6, the connecting piece 32 is fixedly installed on the outer end of the reset rod 31, and the mating piece 34 is installed on the valve body frame 1.
