Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment technology, specifically a fire-fighting device that facilitates nozzle adjustment. Background Technology

[0002] Fire extinguishing equipment is a core component of fire safety assurance and is widely used in various scenarios such as buildings, factories, and warehouses. As a key component of fire extinguishing equipment, the precision of the nozzle's spray angle and position adjustment directly affects the fire extinguishing efficiency and coverage.

[0003] Existing fire extinguishing equipment typically employs two main types of sprinkler head adjustment methods: manual adjustment and simple mechanical adjustment. Manual adjustment requires close-range operation by personnel, posing safety hazards at the fire scene, and suffers from low accuracy and slow response. Simple mechanical adjustment mechanisms often only allow for single-direction adjustment, lacking sufficient freedom of adjustment and failing to meet the multi-angle fire extinguishing needs in complex fire scenarios. Furthermore, the reliability of locking after adjustment is poor, and angle deviations can easily occur due to equipment vibration or water flow impact, affecting the fire extinguishing effect. In addition, some existing automatic adjustable fire sprinklers suffer from complex structures, slow adjustment response, and the inability to achieve remote and precise control. Moreover, the water supply pipeline is prone to being pulled and bent due to multi-angle adjustments of the sprinkler head, leading to seal failure or pipeline damage, further limiting the applicable scenarios of the equipment.

[0004] In response to the aforementioned technical deficiencies, there is an urgent need for a fire extinguishing device that offers high degree of adjustment freedom, reliable locking, convenient operation, and strong adaptability to meet the modern fire protection needs for efficient and precise fire suppression.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1 to 8 As shown, the present invention provides a fire extinguishing device that is easy to adjust the nozzle, including a main body 1, a water supply pipeline 2, an adjustment mechanism 3 and a fire extinguishing nozzle 4. The components work together to realize the functions of fire extinguishing medium delivery and precise nozzle adjustment.

[0023] The main body of the equipment 1 consists of two parts: a water storage tank and a control box. It integrates a power component 5 and a control module 6. The power component 5 is located in the water storage tank and is used to provide stable power for the delivery of fire extinguishing media such as water and fire extinguishing foam, ensuring that the fire extinguishing nozzle 4 has sufficient spray pressure. The control module 6 is installed inside the control box and serves as the control core of the equipment. It is electrically connected to the power component 5 and the adjustment mechanism 3 respectively, so as to realize precise control of power output control and nozzle adjustment.

[0024] One end of the water supply pipeline 2 is connected to the output end of the power assembly 5, and the other end is sealed to the fire extinguishing nozzle 4, used to stably deliver the fire extinguishing medium in the water storage tank to the nozzle. To accommodate the multi-angle movement of the adjustment mechanism 3, the water supply pipeline 2 adopts a flexible metal corrugated pipe with a protective sleeve on the outside. The protective sleeve is precisely matched with the moving parts of the adjustment mechanism 3 and can deform synchronously with the horizontal rotation and vertical adjustment of the adjustment mechanism 3, avoiding sealing failure or damage caused by pipeline pulling or bending. At the same time, the protective sleeve can effectively isolate external debris and protect the pipeline from wear.

[0025] like Figures 1 to 8 As shown, the adjustment mechanism 3 is the core component for realizing multi-angle adjustment of the nozzle, including a fixed base 31, a rotation adjustment component 32 and an angle locking component 33. It has bidirectional adjustment capabilities of horizontal rotation and vertical adjustment, and the locking is reliable after adjustment.

[0026] The fixed base 31 and the main body 1 are detachably fixedly connected, which facilitates equipment installation, inspection and maintenance, while ensuring the overall installation stability of the adjustment mechanism 3. The rotating adjustment assembly 32 includes a horizontal rotating platform 321 and a vertical adjustment frame 322. The horizontal rotating platform 321 is rotatably mounted on the top of the fixed base 31 via a rotating bearing, enabling 360° horizontal rotation. The bottom end of the vertical adjustment frame 322 is hinged to a groove on the upper end face of the horizontal rotating platform 321 via a hinge shaft, allowing for vertical angle adjustment around the hinge shaft. The fire extinguishing nozzle 4 is fixedly mounted on the top of the vertical adjustment frame 322, enabling omnidirectional angle adjustment with the movement of the horizontal rotating platform 321 and the vertical adjustment frame 322.

[0027] To achieve automatic and precise adjustment, both the horizontal rotary table 321 and the vertical adjustment frame 322 are equipped with drive mechanisms: the bottom of the horizontal rotary table 321 has an inner ring gear 3211 in the groove, and the fixed base 31 houses a first drive motor 3212. The output end of the first drive motor 3212 is connected to a drive gear 3213, which meshes with the ring gear 3211. The first drive motor 3212 is electrically connected to the control module 6, which can control the forward and reverse rotation and speed of the first drive motor 3212, thereby driving the horizontal rotary table 321 to achieve horizontal rotation in different directions and at different speeds, and precisely adjust the water flow from the spray nozzles. The vertical adjustment frame 322 extends into the horizontal rotating platform 321 at one end in a disc-shaped structure, with teeth 3221 integrally formed on its surface. A second drive motor 3222 is installed on the outer surface of the horizontal rotating platform 321. The output end of the second drive motor 3222 is fixedly connected to a drive gear 3223 located inside the horizontal rotating platform 321. The drive gear 3223 meshes with the teeth 3221. The second drive motor 3222 is electrically connected to the control module 6. The control module 6 controls the second drive motor 3222 to rotate around the hinge axis, thereby achieving precise adjustment of the nozzle's vertical angle.

[0028] Furthermore, a telescopic mechanism 323 is provided on the vertical adjustment frame 322, which can adjust the spray distance of the nozzle and improve the adaptability of the equipment. The telescopic mechanism 323 includes an electro-hydraulic push rod 3231, a connecting rod 3232, and a limiting plate 3233. The vertical adjustment frame 322 consists of upper and lower parts. The electro-hydraulic push rod 3231 is located inside a slot opened in the lower rod of the vertical adjustment frame 322. The connecting rod 3232 is connected to the extended end of the electro-hydraulic push rod 3231, and the other end is connected to the upper rod of the vertical adjustment frame 322. The telescopic movement of the electro-hydraulic push rod 3231 drives the upper rod to rise and fall, thereby driving the fire extinguishing nozzle 4 to move up and down and adjust the spray distance. The limiting plate 3233 is integrally formed at the insertion end of the connecting rod 3232, which can effectively limit the telescopic stroke of the connecting rod 3232 and avoid damage to the mechanism due to excessive telescopic movement.

[0029] It should be noted that the water supply pipe 2 is fixed to the upper and lower parts of the vertical adjustment frame 322 of the adjustment mechanism 3 by a buckle. The upper and lower parts of the rod are connected by a telescopic mechanism 323. The water supply pipe 2 is positioned at the telescopic mechanism 323 with a margin greater than its telescopic length.

[0030] The angle locking component 33 includes a first locking member 331 and a second locking member 332, which respectively lock the horizontal rotation angle and the vertical adjustment angle, ensuring that the nozzle remains stable after being adjusted to the target angle, and avoiding angle deviation caused by water flow impact or equipment vibration. The first locking element 331 is installed on the surface of the fixed base 31 and located on one side of the horizontal rotating platform 321. It includes a first electromagnetic lock 3311 and a locking groove A3312. The first electromagnetic lock 3311 is installed on the top end face of the fixed base 31, and the locking groove A3312 is arranged in a ring array on the bottom end face of the horizontal rotating platform 321. The locking tongue of the first electromagnetic lock 3311 can engage with the locking groove A3312. After the horizontal rotation angle is adjusted, the control module 6 controls the first electromagnetic lock 3311 to move, and the locking tongue extends into the corresponding locking groove A3312 to lock the horizontal rotating platform 321. The structure of the second locking element 332 is the same as that of the first locking element 331. The second electromagnetic lock 3321 is installed on one side of the hinge position of the horizontal rotating platform 321, and the locking groove B3322 is opened on the side of the hinge end of the vertical adjustment frame 322. After the vertical angle is adjusted, the electromagnetic lock of the second locking element 332 engages with the locking groove to reliably lock the vertical adjustment frame 322.

[0031] like Figures 1 to 8 As shown, to improve adjustment accuracy, angle sensors 7 are respectively installed on the horizontal rotary table 321 and the vertical adjustment frame 322. The angle sensors 7 are electrically connected to the control module 6, which can collect the horizontal rotation angle and vertical adjustment angle of the nozzle in real time, and feed the angle data back to the control module 6 to form a closed-loop control, ensuring that the nozzle is accurately adjusted to the target angle.

[0032] To facilitate the movement and fixed parking of the equipment, a moving component 8 is provided at the bottom of the main body 1 of the equipment. The moving component 8 includes a base plate 81 and casters 82. The base plate 81 is located below the main body 1 of the equipment, and the casters 82 are symmetrically installed at the four corners of the bottom of the base plate 81. A brake pedal is installed on the casters 82. The operator can push the equipment to a designated position at the fire scene and lock the casters 82 by stepping on the brake pedal to fix the equipment in place and prevent the equipment from moving during the fire extinguishing process.

[0033] To enable remote control, the control module 6 is also connected to a wireless communication module, which can wirelessly connect to remote control terminals such as fire control room consoles and handheld remote controls. Operators can send adjustment commands from a safe area through the remote control terminal, which are transmitted to the control module 6 via the wireless communication module. The control module 6 then controls the adjustment mechanism 3 to achieve remote control of the sprinkler head adjustment. At the same time, the angle data collected by the angle sensor 7 and the working status data of the power component 5 can be fed back to the remote control terminal through the wireless communication module, so that operators can monitor the equipment's operating status in real time.

[0034] Working principle and process: When a fire occurs, the operator pushes the equipment to the designated location on site and steps on the brake pedal of the caster wheel 82 to fix the equipment; the equipment is started through the remote control terminal or the local control panel of the equipment, the control module 6 starts the high-pressure water pump of the power component 5, and the fire extinguishing medium is delivered to the fire extinguishing nozzle 4 through the water supply pipeline 2. At this time, the nozzle is in the initial position.

[0035] Based on the fire location, the operator sends an angle adjustment command via a remote control terminal: If the horizontal angle needs adjustment, the control module 6 controls the first drive motor 3212 to rotate forward or backward, the drive gear 3213 drives the ring gear 3211 to rotate, which in turn drives the horizontal rotary table 321 to rotate. The angle sensor 7 on the horizontal rotary table 321 collects the rotation angle in real time and feeds it back to the control module 6. When the target angle is reached, the control module 6 stops the first drive motor 3212 and simultaneously controls the first electromagnetic lock 3311 of the first locking member 331 to move, and the locking tongue engages with the corresponding locking groove A3312 to complete the horizontal angle locking; If the vertical angle needs adjustment, the control module 6 controls the second drive motor 3222 to move, the drive gear 3223 drives the teeth 3221 to rotate, causing the vertical adjustment frame 322 to rotate around the hinge axis. The angle sensor 7 in the vertical direction collects the angle data and feeds it back. After the target angle is reached, the second locking member 332 moves to lock.

[0036] If the spray distance needs to be adjusted, the control module 6 controls the extension and retraction of the electro-hydraulic push rod 3231 of the telescopic mechanism 323, driving the rod body on the vertical adjustment frame 322 to rise and fall, thus moving the fire extinguishing nozzle 4 to a suitable height. The limit plate 3233 limits the maximum extension and retraction stroke to prevent damage to the mechanism. During the fire extinguishing process, the angle sensor 7 continuously collects angle data. If an angle deviation occurs, the control module 6 can automatically control the drive motor and locking components to correct the angle and relock, ensuring stable fire extinguishing effect.
