Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire-fighting equipment technology, specifically to an integrated alarm and fire-extinguishing device that integrates multiple sensors. Background Technology
[0002] Suspended dry powder fire extinguishers are fire-fighting devices that do not require piping, are installed by hanging or wall mounting, and can be automatically activated. Due to their simple structure, convenient installation, and the fact that the extinguishing agent has no toxic or corrosive residue, they are increasingly being used in the fire protection field, especially in enclosed spaces such as motor rooms, power distribution rooms, and equipment rooms.
[0003] To meet the fire extinguishing needs in complex fire situations and improve the accuracy of automatic fire extinguishing, suspended dry powder fire extinguishers generally integrate multiple sensors such as temperature and smoke sensors. The fire extinguisher is activated by a linkage control method using a temperature-sensing glass bulb or an electric initiator. Some fire extinguishers also have built-in alarm devices. When a fire occurs, the fire extinguisher automatically activates and simultaneously controls the alarm device to send an alarm signal, forming an integrated alarm and fire extinguishing system.
[0004] A smart suspended fire extinguishing device is disclosed in Chinese utility model patent with publication date of March 22, 2024 and publication number CN220632874U. The device includes a fixed bracket, a suspended fire extinguisher, a temperature extinguishing device and a smoke extinguishing device. A main controller is connected to the suspended fire extinguisher. The temperature extinguishing device and the smoke extinguishing device are electrically connected to the main controller. An electric heating starter is installed at the bottom of the fire extinguisher. When a fire occurs, the temperature sensor or the smoke sensor transmits a signal to the main controller, and the main controller transmits a signal to the electric heating starter to activate the fire extinguishing.
[0005] Existing suspended fire extinguisher systems have the following problems: Suspended fire extinguishers are usually fixed in one location, resulting in limited coverage. Their extinguishing effect is poor when the fire source shifts. In large spaces, to meet fire extinguishing needs, multiple fire extinguishers need to be densely installed in different areas, increasing fire protection costs and easily creating blind spots. Utility Model Content
[0006] The purpose of this invention is to provide a multi-sensor fusion alarm and fire extinguishing integrated device to address the above problems, and to solve the problem that existing fire extinguishers have limited coverage and cannot adapt to different fire source locations.
[0007] To achieve the above objectives, this utility model discloses an integrated alarm and fire extinguishing device with multi-sensor fusion, including a suspended fire extinguisher. The integrated device also includes a swing arm installed on the indoor ceiling and driven to rotate horizontally by a first drive mechanism. A sliding seat is installed at the bottom of the swing arm and driven to slide along the length of the swing arm by a second drive mechanism. The suspended fire extinguisher is detachably installed at the bottom of the sliding seat.
[0008] By employing the aforementioned structure, the suspended fire extinguisher is driven to rotate horizontally and slide along the length of its swing arm via the first and second drive mechanisms. This not only expands the extinguisher's coverage area but also improves extinguishing efficiency in complex fire situations or when the fire source is located elsewhere. Furthermore, in spacious locations, fire extinguishers only need to be placed within their movable range, saving space, reducing firefighting costs, and effectively avoiding blind spots.
[0009] As another improvement of this utility model, the integrated device also includes a side support mounted on the wall and an arc-shaped hanging rail mounted on the indoor ceiling. One end of the swing arm is rotatably mounted on the side support and the other end is slidably mounted on the hanging rail.
[0010] By adopting the above structure, the structural stability of the integrated device is improved through the side support and the hanging rail, which makes the swing arm bear a larger load and can support heavier fire extinguishers.
[0011] The first drive mechanism includes a central shaft fixedly connected to the swing arm and a first motor mounted on a side support. A transmission mechanism is connected between the power output end of the first motor and the central shaft. The transmission mechanism includes a driving gear connected to the power output end of the first motor and a driven gear meshing with the driving gear and mounted on the central shaft.
[0012] With the above structure, the swing arm can rotate horizontally around the central axis, enabling the suspended fire extinguisher to rotate horizontally.
[0013] The second drive mechanism includes a lead screw coaxially connected to the slide and a second motor, with the lead screw being driven by the power output end of the second motor. The swing arm includes a top plate and a front baffle and a motor bracket connected to both ends of the top plate. A rear baffle is provided on the bottom surface of the top plate between the front baffle and the motor bracket. The two ends of the lead screw are rotatably mounted on the front baffle and the rear baffle, respectively. The second motor is fixedly mounted on the motor bracket, and the power output end of the second motor is connected to the lead screw via a coupling.
[0014] With the above structure, the sliding block can slide along the length of the swing arm, enabling the suspended fire extinguisher to slide along the length of the swing arm.
[0015] As another improvement of this utility model, the side support is L-shaped, with a support seat on its horizontal plate and a positioning frame on its vertical plate. The top end of the central shaft is fixedly connected to the bottom of the motor bracket, and the upper and lower ends of the central shaft are rotatably mounted on the positioning frame and the support seat, respectively.
[0016] With the above structure, the support and positioning frame limit the center axis, thus improving the stability of the center axis.
[0017] As another improvement of this utility model, a roller is connected to the top of the swing arm, which rolls in cooperation with the hanging rail.
[0018] With the above structure, the resistance when the swing arm rotates horizontally around the central axis can be reduced by the rollers, making the swing arm rotate more smoothly.
[0019] As another improvement of this utility model, a housing is provided on the side support, and the top end of the central shaft protrudes through the top of the housing.
[0020] The above structure protects the internal structure from dust and moisture in the air, effectively preventing the internal structure from aging easily.
[0021] As another improvement of this utility model, a connecting plate is provided below the slide, on which an alarm and / or smoke sensor are detachably mounted.
[0022] With the above structure, the alarm and / or smoke sensor can be detachably connected to the connecting plate, which not only saves installation space, but also facilitates the quick installation, maintenance and replacement of the alarm and smoke sensor.
[0023] In summary, the beneficial effects of this utility model are as follows: This utility model, by rotating the suspended fire extinguisher horizontally and sliding it along the length of the swing arm, solves the problems of limited coverage and poor extinguishing effect of existing suspended fire extinguishers when the fire source is shifted. Furthermore, in larger spaces, fire extinguishers only need to be placed within their movable range, saving space, reducing fire protection costs, and effectively avoiding blind spots in fire suppression.

The main controller controls the second motor 32 to reverse. By controlling the forward and reverse rotation of the second motor 32, the slide 5 is driven to slide back and forth along the length direction of the swing arm 4.

[0046] Working principle: In use, the first motor 22 drives the central shaft 21 to rotate, thereby causing the swing arm 4 to swing horizontally, which in turn moves the suspended fire extinguisher 1 along the arc-shaped trajectory of the hanging rail 7. The second motor 32 drives the sliding base 5 and the suspended fire extinguisher 1 to slide along the length of the swing arm 4, allowing the suspended fire extinguisher 1 to move within a fan-shaped area. In specific use, the speed at which the suspended fire extinguisher 1 slides along the length of the swing arm 4 is significantly faster than its speed of rotation in the horizontal direction, thus forming a fan-shaped sweeping surface with the movement trajectory of the suspended fire extinguisher 1. This allows the movable range of the fire extinguisher to fully cover the entire space below the fan-shaped area formed by the hanging rail 7 and the central shaft 21.
[0047] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
