Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire extinguishing equipment technology, specifically to an ultrafine dry powder fire extinguishing device. Background Technology
[0002] Ultrafine dry powder fire extinguishing technology is the most efficient fire extinguishing technology available today. Since the extinguishing time is usually less than 5 seconds and there are no requirements for the sealing of the application site, it is very suitable for protecting objects in fully enclosed spaces, semi-enclosed spaces, or open outdoor spaces.
[0003] When using a suspended ultrafine dry powder fire extinguishing device, a mounting bracket is needed to fix the position of the device so that the spray tip is above the protected area.
[0004] Existing ultrafine dry powder fire extinguishing devices require adjustment of the spray angle after installation if the protected object moves. Traditional angle adjustment devices typically use motors, shafts, and electronic components. However, in the event of a fire, these electronic components are prone to damage or malfunction under high temperatures, leading to uncontrollable angle adjustments and preventing the device from effectively extinguishing fires on protected objects. Therefore, those skilled in the art have developed an ultrafine dry powder fire extinguishing device to address the problems described in the background section. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides an ultrafine dry powder fire extinguishing device. This addresses the problem that while most ultrafine dry powder fire extinguishing devices rely on motors, shafts, and electronic components for angle adjustment, these components are prone to damage or malfunction at high temperatures during a fire. This results in uncontrollable angle adjustments, preventing the device from effectively extinguishing fires on protected objects within the protected area.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: an ultrafine dry powder fire extinguishing device, comprising a wall and a ball head seat, wherein the ball head seat is fixedly installed with the wall, a ball head body is provided inside the ball head seat, a connecting rod is connected to the bottom end of the ball head body, a tank is installed at the top end of the connecting rod, a nozzle is installed at the bottom of the tank, a limiting sleeve is installed on one side of the tank, a threaded sleeve is provided inside the limiting sleeve, a screw is threadedly connected inside the threaded sleeve, and a Y-shaped bracket is rotatably engaged at the top of the screw.
[0009] Preferably, the top two ends of the Y-shaped bracket are in contact with the wall. When the item to be protected moves within the protected area, the Y-shaped bracket at the top of the screw can be moved upward by rotating the screw to press against the wall. At this time, the tank is more stable under the support of the Y-shaped bracket and will not shake. The ball head body drives the tank and the nozzle to tilt during the upward movement of the Y-shaped bracket, so that the nozzle of the tank is aimed at the item to be protected.
[0010] Preferably, the two side walls of the limiting sleeve are provided with sliding grooves, and the two side walls of the threaded sleeve are provided with limiting bolts. The limiting bolts are slidably engaged with the sliding grooves. The threaded sleeve moves in the sliding grooves within the limiting sleeve through the limiting bolts, which can compensate for the tilt of the screw to a certain angle and prevent the upper and lower ends of the screw from being squeezed and blocked.
[0011] Preferably, a limiting groove is vertically formed inside the screw, and a pull rod is provided in the limiting groove, the pull rod being slidably engaged with the limiting groove.
[0012] Preferably, a second magnet is installed at the top of the pull rod, and a first magnet is installed at the top of the inner wall of the limiting groove. The pull rod is magnetically connected to the first magnet through the second magnet. When it is necessary to adjust the angle of the tank, the pull rod can be pulled out to extend the length of the screw and rotate it. After the angle adjustment is completed, the pull rod can be pushed inward to retract into the screw and be magnetically connected by the magnet, so as to avoid the pull rod obstructing pedestrians.
[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides an ultrafine dry powder fire extinguishing device, which has the following features:
[0015] Beneficial effects:
[0016] Through design, the ultrafine dry powder fire extinguishing device in this utility model consists of a canister, nozzle, ball head body, limiting sleeve, screw, and Y-shaped bracket. A ball head seat is pre-installed on the wall, and the canister is connected to the ball head body via the ball head seat. In this connection structure, the canister is in a swaying state. A threaded sleeve inside the limiting sleeve on one side of the canister is threadedly connected to a screw. The top of the screw is rotatably engaged with a Y-shaped bracket. When the object to be protected moves within the protected area, rotating the screw causes the Y-shaped bracket at the top of the screw to move upwards and press against the wall. At this time, the canister's stability is increased under the support of the Y-shaped bracket, preventing swaying. Furthermore, the ball head body tilts the canister and nozzle during the upward movement of the Y-shaped bracket, ensuring the nozzle's spray direction is aligned with the object to be protected. This avoids the problem of uncontrollable angles of the ultrafine dry powder fire extinguishing device due to damage or malfunction of electronic components under high temperatures, which would otherwise prevent the ultrafine dry powder fire extinguishing device from effectively extinguishing fires on protected objects within the protected area.
