The support rod and adjusting screw are threadedly connected, allowing flexible adjustment of the overall length of the device to adapt to different operating height requirements.

Description

Technical Field

[0001] This utility model relates to the field of forest fire prevention technology, specifically a forest fire extinguishing device. Background Technology

[0002] In forest fire fighting operations, fire extinguishers are commonly used portable fire extinguishing tools. They are mostly used in forest areas with complex terrain, dense vegetation, and changeable fire conditions. Traditional fire extinguishers mostly adopt fixed or bolt-fastened connection structures, which have problems such as inconvenience in replacement and low disassembly and assembly efficiency. Especially when continuous operation or fire development requires the replacement of different types of fire extinguishers, operators often need to carry special tools, which takes a long time and seriously affects the fire fighting response speed and operational efficiency. While some existing detachable fire extinguisher structures allow for quick replacement, they generally suffer from weak connections and are prone to loosening due to high-frequency vibration or impact during use. For example, some structures rely solely on snap-fit ​​or single-point locking, resulting in insufficient clamping force and uneven stress. Prolonged use can easily cause the extinguisher head to shift or even detach, reducing fire extinguishing efficiency and potentially leading to operational safety accidents. Furthermore, in harsh outdoor environments such as high temperatures, smoke, and slippery conditions, operators wearing protective gear experience reduced operational flexibility, placing higher demands on the reliability and ease of operation of the connection structure.

[0020] Example 1 Reference Figure 1-4 This is the first embodiment of the present invention, which provides a fire extinguishing assembly 1 including a fire extinguishing paddle 101, a support rod 102 and an adjusting screw 103. The upper end of the fire extinguishing paddle 101 contacts the lower end of the support rod 102. The inner wall of the support rod 102 is threadedly connected to the surface of the adjusting screw 103. A clamping mechanism 2 is provided at the upper end of the fire extinguishing paddle 101. A limiting mechanism 3 is provided on the clamping mechanism 2. The clamping mechanism 2 is used to replace different types of fire extinguishing paddles 101. The limiting mechanism 3 is used to lock the clamping mechanism 2.

[0021] Specifically, it solves the problems of inconvenient replacement and unstable connection of the existing fire extinguishing beater 101. The clamping mechanism 2 can be adapted to the quick installation and disassembly of different types of fire extinguishing beaters 101, improving work efficiency. The limiting mechanism 3 locks after clamping to prevent loosening due to vibration or force during use, ensuring connection reliability. At the same time, the threaded engagement between the support rod 102 and the adjusting screw 103 enables flexible adjustment of the overall length to adapt to different fire locations and operating height requirements, improving the applicability and ease of operation of the equipment.

[0022] Furthermore, the overall length can be adjusted in real time through the threaded engagement between the support rod 102 and the adjusting screw 103, and the engagement between the clamping mechanism 2 and the limiting mechanism 3 allows for flexible replacement and installation of the fire extinguishing beater 101.

[0023] Example 2 The second embodiment of this utility model provides a clamping mechanism 2 including a rotating disk 201, a double-ended screw 202, a sliding block 203, a clamping plate 204, and a protective cover 205. The surface of the rotating disk 201 is fixedly connected to the surface of the double-ended screw 202. The surface of the double-ended screw 202 is threadedly connected to the inner wall of the sliding block 203. The surface of the sliding block 203 is fixedly connected to the surface of the clamping plate 204. The surface of the rotating disk 201 is rotatably connected to the surface of the protective cover 205. Both ends of the double-ended screw 202 are rotatably connected to the inner wall of the protective cover 205. The inner wall of the protective cover 205 is fixedly connected to the surface of the support rod 102. Both ends of the double-ended screw 202 are rotatably connected to the upper inner wall of the support rod 102. The inner wall of the protective cover 205 is in contact with the surface of the fire extinguishing paddle 101. The surface of the clamping plate 204 is in sliding contact with the inner wall of the fire extinguishing paddle 101 through a sliding groove. The surface of the sliding block 203 is slidably connected to the inner wall of the protective cover 205 through a sliding groove.

[0024] Specifically, this design solves the problems of low replacement efficiency and unstable connection of traditional fire extinguishing beaters 101. By rotating the rotating disk 201 to drive the double-headed screw 202 to rotate, the reverse threads at both ends of the screw drive the two sliding blocks 203 to move synchronously towards or away from each other, realizing the movement and precise positioning of the clamping plate 204. This allows the clamping plate 204 to quickly embed into the groove inside the fire extinguishing beater 101 for reliable clamping. This structure is easy to operate, has uniform clamping force, and is suitable for the rapid replacement of various specifications of fire extinguishing beaters 101, improving the emergency response capability and safety of the equipment in complex field environments.

[0025] Furthermore, in forest fire prevention operations, selecting and using the appropriate fire extinguishing device 101 is a crucial step in ensuring fire suppression efficiency and operational safety. First, a comprehensive assessment must be made based on the type of forest vegetation, the amount of combustible material, and environmental conditions to select a fire extinguishing device 101 of appropriate material and specifications. For example, in densely shrub areas, a high-strength, wear-resistant metal head is preferable, while in sparsely vegetated areas, lightweight composite materials can be used to reduce the workload. After selecting the fire extinguishing device 101, align its lower connecting part with the installation interface at the top of the support rod 102 and insert it smoothly for initial positioning. At this time, the clamping plate 204 inside the protective cover 205 at the upper end of the support rod 102 should be accurately aligned with the pre-reserved sliding groove structure at the lower end of the fire extinguishing device 101. After preparing for the subsequent fixing operation, the rotating disk 201 at the upper end of the support rod 102 is manually rotated to drive the internal double-headed screw 202 to rotate synchronously. Since the two ends of the double-headed screw 202 are machined with threads in opposite directions, when it rotates, the two sliding blocks 203 that mesh with the threads will move synchronously in opposite directions along the axial direction under the guidance of the inner wall of the protective cover 205. The movement of the sliding blocks 203 will then push the clamping plate 204 connected to it to extend laterally, so that it can be accurately embedded into the corresponding groove structure at the lower end of the fire extinguishing paddle 101, thereby achieving clamping and fixing. This symmetrical clamping structure can ensure that the fire extinguishing paddle 101 is subjected to uniform force and has a stable connection, effectively preventing loosening or displacement during the fire extinguishing process.

[0026] Example 3 The third embodiment of this utility model provides a limiting mechanism 3 including a limiting rod 301, an elastic block 302, and a mating hole 303. The elastic block 302 is sleeved on the outer surface of the limiting rod 301. The mating hole 303 is opened at the right end of the protective cover 205. The surface of the limiting rod 301 is slidably connected to the inner wall of the rotating disk 201 through a sliding groove. The two ends of the elastic block 302 are fixedly connected to the rotating disk 201 and the surface of the limiting rod 301, respectively. The surface of the limiting rod 301 is in contact with the inner wall of the mating hole 303.

[0027] Specifically, it solves the problem of the clamping mechanism 2 becoming loose and falling off due to vibration or external force during use. After clamping is completed, the limiting rod 301 is inserted into the mating hole 303 on the protective cover 205. The elastic deformation of the elastic block 302 is used to achieve automatic locking and self-locking, effectively limiting the rotation of the rotating disk 201 and preventing the double-headed screw 202 from rotating unexpectedly, thereby ensuring the continuous stability of the clamping structure. The limiting mechanism 3 has a simple structure and is easy to operate, which significantly improves the safety and reliability of the connection of the fire extinguishing paddle 101 and is suitable for the needs of forest fire prevention operations in high-intensity and complex environments.

[0028] Furthermore, after clamping and fixing, a safety locking operation is required to further improve the reliability of the connection. The preset limiting rod 301 inside the rotating disk 201 is aligned with the corresponding mating hole 303 on the outer wall of the protective cover 205 and inserted to restrict the free rotation of the rotating disk 201 and prevent the double-headed screw 202 from loosening due to vibration or external force. The bottom of the limiting rod 301 is provided with an elastic block 302, which is compressed and deformed during insertion. After entering the mating hole 303, it relies on its own elastic recovery force to achieve self-locking, ensuring that the limiting rod 301 is firmly embedded. At this point, the replacement and installation process of the fire extinguishing beater 101 is completed, and the equipment enters the operable state, which can be used stably in complex forest environments, ensuring the continuity and safety of fire fighting operations.

[0029] Working principle: In forest fire prevention operations, selecting and using the appropriate fire extinguishing beater 101 is crucial for ensuring both fire suppression efficiency and operational safety. First, a comprehensive assessment must be made based on the type of forest vegetation, the amount of combustible material, and environmental conditions to select a fire extinguishing beater 101 of suitable material and specifications. For example, in densely shrubbed areas, a high-strength, wear-resistant metal head is preferable, while in sparsely vegetated areas, lightweight composite materials can be used to reduce the workload. After selecting the fire extinguishing beater 101, align its lower connecting part with the mounting interface at the top of the support rod 102 and insert it smoothly. After initial positioning, the clamping plate 204 inside the protective cover 205 at the upper end of the support rod 102 should be accurately aligned with the pre-reserved sliding groove structure at the lower end of the fire extinguishing paddle 101 to prepare for subsequent fixing operations. Next, by manually rotating the rotating disk 201 at the upper end of the support rod 102, the double-ended screw 202 connected inside it is driven to rotate synchronously. Since the two ends of the double-ended screw 202 are respectively machined with threads of opposite directions, when it rotates, the two sliding blocks 203 that mesh with its threads will be guided by the inner wall of the protective cover 205 along... The sliding block 203 moves synchronously in opposite directions along the axis, which in turn pushes the clamping plate 204 connected to it to extend laterally, so that it is precisely embedded in the corresponding groove structure at the lower end of the fire extinguishing paddle 101, thereby achieving clamping and fixing. This symmetrical clamping structure can ensure that the fire extinguishing paddle 101 is subjected to uniform force and has a stable connection, effectively preventing loosening or displacement during the fire extinguishing process. After the clamping and fixing is completed, in order to further improve the connection reliability, a safety locking operation is required, aligning the preset limit rod 301 inside the rotating disk 201 with the limit rod 301 on the outer wall of the protective cover 205. The corresponding mating hole 303 is inserted to restrict the free rotation of the rotating disk 201 and prevent the double-headed screw 202 from loosening due to vibration or external force causing it to rotate in the opposite direction. The bottom of the limiting rod 301 is provided with an elastic block 302, which is compressed and deformed during insertion. After entering the mating hole 303, it relies on its own elastic restoring force to achieve self-locking, ensuring that the limiting rod 301 is firmly fitted. At this point, the replacement and installation process of the fire extinguishing beater 101 is completed, and the equipment enters the operable state, which can be used stably in complex forest environments, ensuring the continuity and safety of fire fighting operations.

[0030] In summary, the combination of the fire extinguishing paddle and support rod connection structure, the synchronous clamping mechanism driven by the double-headed screw, and the anti-loosening locking device composed of the limit rod and elastic block enables the fire extinguishing paddle to be quickly replaced, securely clamped, and reliably prevented from falling off during use in complex field environments, effectively improving the ease of operation and safety of forest fire fighting equipment.
