Description

Technical Field

[0001] This utility model belongs to the field of wind-powered fire extinguishing technology, and in particular relates to a wind-powered fire extinguisher with controllable airflow direction. Background Technology

[0002] A wind-powered fire extinguisher, also known as a blower, is a device that uses wind power to extinguish fires. It primarily works by generating a high-speed airflow to extinguish flames and heat, thus achieving the purpose of fire suppression. The main components of a wind-powered fire extinguisher include a centrifugal fan, a blower duct, and a gasoline engine. However, when extinguishing a fire, it needs to be placed close to the base of the flames to increase the extinguishing effect. But placing it too close to the flames can easily burn the user. This paper proposes a structure that allows adjustment of the distance between the wind-powered fire extinguisher and the fire source. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a wind-powered fire extinguisher with controllable airflow direction, thus solving the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wind-powered fire extinguisher with controllable airflow direction, comprising a frame and an adjustment assembly for controlling the fire extinguisher's proximity to a fire source; the adjustment assembly comprises a handle, a lead screw, and a slide, wherein the handle is fixedly connected to the frame, the lead screw is rotatably connected to the frame, the slide is threadedly connected to the lead screw, and the other side of the slide is slidably connected to the frame.

[0005] Beneficial effects

[0006] This utility model provides a wind-powered fire extinguisher with controllable airflow direction, which has the following advantages compared with the prior art:

[0007] The user places the wind-powered fire extinguisher between two clamping plates and manually rotates the turntable connected to the left-hand screw. This causes the left-hand screw to drive the right-hand screw fixed to it to rotate synchronously. At this time, the sliding cylinders threaded onto the left-hand and right-hand screws begin to move linearly, causing the clamping plates fixed to them to slide synchronously. The two clamping plates then begin to move in opposite directions, thus working together to clamp the wind-powered fire extinguisher. The anti-slip pads on these plates further enhance the restraint effect on the wind-powered fire extinguisher. The user then holds the handle, aligning the head of the frame with the base of the flame, and starts motor B. The screw fixed to its output shaft rotates synchronously, causing the sliding carriage threaded onto the screw to begin moving along... The extinguisher slides linearly at its connection with the frame, thereby bringing the wind-powered fire extinguisher, which is clamped and fixed between two plates, closer to the fire source and closer to the root of the fire, thus increasing the extinguishing efficiency. The user can then activate the wind-powered fire extinguisher to extinguish the fire with wind power. When it is necessary to adjust the airflow direction, the user starts motor A, causing the screw fixedly connected to its output shaft to rotate synchronously. This causes the sliding plate threaded on it to start moving linearly along its connection with the frame, and then causes the rack fixedly connected to its bottom to move synchronously. When the rack moves to the gear, it can drive the gear meshing with it to start rotating, which in turn drives the wind-powered fire extinguisher to rotate synchronously, thereby adjusting the airflow direction of the wind-powered fire extinguisher.

[0022] Specifically, a left-hand lead screw 209 is rotatably connected to the connecting plate 205, and the other end of the left-hand lead screw 209 is fixedly connected to a right-hand lead screw 301. The right-hand lead screw 301 is rotatably connected to the connecting plate 205.

[0023] For the above examples, those skilled in the art should know that when implementing the above technical solutions, it is not limited to the specific left-hand lead screw 209 and right-hand lead screw 301 described in the above embodiments. For example, the left-hand lead screw 209 and right-hand lead screw 301 should be lead screws with self-locking effect. The purpose of this setting is to facilitate the increase of the limiting effect on the slide cylinder 208 connected to the thread through this setting.

[0024] Specifically, the left-hand lead screw 209 and the right-hand lead screw 301 are respectively threaded with slide cylinders 208, and the two slide cylinders 208 are fixedly connected to the clamping plate 206.

[0025] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific clamp 206 described in the above embodiments. For example, the clamp 206 and the contact surface of the wind-powered fire extinguisher 207 are provided with anti-slip rubber pads. The purpose of this setting is to facilitate the increase of the limiting effect on the wind-powered fire extinguisher 207.

[0026] Specifically, a gear 302 is fixedly connected to the top of the shaft 204. The gear 302 meshes with the rack 303 during the sliding process. The rack 303 is fixedly connected to the bottom of the slide plate 304.

[0027] Regarding the above examples, those skilled in the art should understand that the implementation of the above technical solutions is not limited to the specific sliding plate 304 described in the above embodiments. For example, the connection between the sliding plate 304 and the frame 101 is provided with a damping rubber strip. The purpose of this arrangement is to increase the damping of its sliding, thereby making it...

[0028] Specifically, the slide plate 304 is threadedly connected to the screw 305, the slide plate 304 is slidably connected to the frame 101, the screw 305 is rotatably connected to the frame 101, one end of the screw 305 is fixedly connected to the output shaft of the motor A306, and the motor A306 is fixedly connected to the frame 101.

[0029] For the above examples, those skilled in the art should know that when implementing the above technical solutions, it is not limited to the specific motors A306 and B307 described in the above embodiments. For example, motors A306 and B307 should be selected as motors with multiple adjustable speeds. The purpose of this setting is to facilitate the adjustment of the sliding speed of the slide plate 304 and the slide 203.

[0030] In this embodiment of the invention, the user places the wind-powered fire extinguisher 207 between two clamping plates 206 and manually rotates the turntable connected to the left-hand lead screw 209. This causes the left-hand lead screw 209 to drive the right-hand lead screw 301, which is fixedly connected to it, to rotate synchronously. At this time, the sliding cylinder 208 threadedly connected to the left-hand lead screw 209 and the right-hand lead screw 301 begins to move linearly, driving the clamping plates 206 fixedly connected to them to slide synchronously. The two clamping plates 206 then begin to move towards each other, thus cooperating to clamp the wind-powered fire extinguisher 207. At the same time, the anti-slip rubber pads provided on them can further increase the limiting effect on the wind-powered fire extinguisher 207. Then, the user holds the handle 201, aligns the head end of the frame 101 with the base of the flame, and then starts the motor B307. At this time, the lead screw 202 fixedly connected to its output shaft rotates synchronously, causing the screw 202 threadedly connected to the lead screw 201 to rotate synchronously. The slide 203 on 02 begins to slide linearly along its sliding connection with the frame 101, thereby driving the wind-powered fire extinguisher 207, which is clamped and fixed between the two clamps 206, closer to the fire source, bringing it closer to the root of the fire source, thus increasing the fire extinguishing efficiency. Then, the user can start the wind-powered fire extinguisher 207 to extinguish the fire with wind power. When it is necessary to adjust the airflow direction, the user starts the motor A306, causing the screw 305 fixedly connected to its output shaft to rotate synchronously, and driving the slide plate 304 threaded on it to begin to move linearly along its connection with the frame 101, and to begin to drive the rack 303 fixedly connected to its bottom to move synchronously. When the rack 303 moves to the gear 302, it can drive the gear 302 meshing with it to start rotating, thus driving the wind-powered fire extinguisher 207 to rotate synchronously, thereby adjusting the airflow direction of the wind-powered fire extinguisher 207.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0032] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.
