This utility model discloses a dual-purpose automatic sprinkler intelligent fire-fighting device, relating to the field of fire-fighting equipment technology. It includes a mounting plate with several ring-shaped mounting holes extending through its upper edge. Height adjustment components are fixedly installed on the lower left and right sides of the mounting plate, and a sprinkler adjustment component is fixedly installed at the bottom of the height adjustment components. This dual-purpose automatic sprinkler intelligent fire-fighting device, through its height adjustment components, can extend or shorten the distance between the mounting plate and the base according to the fire situation, thereby adjusting the height of the three sprinkler heads from the ground. It can automatically adapt to the height of the fire source, making it highly adaptable. The sprinkler adjustment components utilize the expansion of low-boiling gases to adjust the angle of the three hoses. The three sprinkler heads are arranged in a ring, achieving circumferential and radial coverage in conjunction with the automatic adjustment mechanism. It has a high degree of automation, enabling the device to both spray and adjust functions.

This utility model discloses a combustion rack device with adjustable function, including a base, a roasting box, and a combustion chamber and a burner head disposed inside the roasting box, as well as nested fixing columns and fixing rods. The fixing columns and fixing rods are located at the corners of the base and the roasting box. A roasting box is disposed inside the roasting box, and removal plates are fixedly connected to the left and right sides of the upper end of the roasting box, respectively engaging with the left and right sides of the upper end of the roasting box. This combustion rack device with adjustable function facilitates appropriate adjustment of the height of the roasting box. During combustion, the cover plate engages with the upper end of the roasting box to prevent heat loss. Furthermore, combined with the removal plates fixed to the left and right sides of the upper end of the roasting box, the outer side of the upper end of the roasting box is located outside the roasting box. During cleaning, only the removal plates need to be pulled to remove the roasting box from the roasting box to clean the residue, without needing to reach into the roasting box for operation.
