[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a high-efficiency fire extinguishing device that combines high-pressure fine water mist and ultrafine dry powder, which has the following beneficial effects:

[0018] 1. This high-efficiency fire extinguishing device, which combines high-pressure fine water mist and ultrafine dry powder, features a fixing mechanism and a connecting mechanism. The mounting base is secured to the fixing plate via a locking block, ensuring a stable connection of the discharge pipe and preventing dry powder leakage. When the discharge pipe needs to be disassembled, the U-shaped frame is pulled to move outward from the mounting groove. The cylinder slides along the inclined surface of the wedge block, forcing the wedge block to move outward. This, in turn, compresses the telescopic spring of the moving plate, causing the locking block to disengage from the locking groove of the fixing plate. At this point, the discharge pipe is no longer constrained and can be easily removed from the mounting base, thus achieving the purpose of easy disassembly and replacement of the discharge pipe.

[0019] 2. This high-efficiency fire extinguishing device, which combines high-pressure fine water mist with ultra-fine dry powder, features a moving mechanism and a limiting mechanism. The moving wheels facilitate the overall movement of the device. During fire extinguishing operations, the moving wheels need to be locked in place. Turning the handle moves the push rod upward, causing the push block to lose pressure. The connecting spring then pushes the moving frame to the left, and the locking plate engages with the limiting groove of the limiting wheel, fixing the limiting wheel and preventing the moving wheels from rotating. This achieves the purpose of having a stable structure. When it is necessary to move the device, turning the handle moves the push rod downward through the connecting plate, causing the connecting plate to engage with the inside of the right-angle plate. This pushes the push block down along the guide frame, pressing against the inclined surface of the triangular block, forcing the moving frame to overcome the elasticity of the connecting spring and move to the right. Finally, the locking plate disengages from the limiting wheel, allowing the device to be moved, further facilitating its use. Attached Figure Description

Detailed Implementation

[0031] 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.

[0032] Please see Figure 1-10This invention provides a technical solution: a high-efficiency fire extinguishing device combining high-pressure fine water mist and ultrafine dry powder, comprising a base plate 1, an outer casing 2 fixedly installed on the top of the base plate 1, a dry powder extinguishing agent storage tank 3 movably installed on the inner bottom wall of the outer casing 2, a stabilizing ring 6 fixedly installed on the right side of the inner wall of the outer casing 2, a door 9 movably installed on the front side of the inner wall of the outer casing 2, a liquid storage tank 10 fixedly installed on the left side of the inner wall of the outer casing 2 and fixedly connected to its inner bottom wall, a level gauge 11 movably installed on the front side of the inner wall of the liquid storage tank 10 extending to the front of the door 9, and a pump body 12 fixedly installed on the top of the liquid storage tank 10. The inlet end of the pump body 12 is fixedly installed with an inlet pipe 13 extending to the inside of the storage tank 10. The outlet end of the pump body 12 is fixedly installed with an outlet pipe 14 extending to the top of the outer casing 2. The inner top wall of the outer casing 2 is fixedly installed with a mounting bracket 15 that is fixedly connected to the left side of its inner wall. The inner side of the mounting bracket 15 is movably installed with a controller 16 extending to the left side of the outer casing 2. The top of the dry powder extinguishing agent storage tank 3 is provided with a fixing mechanism 4. The inner side of the fixing mechanism 4 is provided with a connecting mechanism 5 extending to the top of the outer casing 2. The bottom of the base plate 1 is provided with a moving mechanism 7. The top of the base plate 1 is provided with a limiting mechanism 8 extending to its bottom and connected to the moving mechanism 7.

[0033] An infusion tube extending to the left side of the outer box 2 is fixedly installed on the inner top wall of the liquid storage tank 10, and a mesh box fixedly connected to the right side of its inner wall is fixedly installed on the inner bottom wall of the liquid storage tank 10. One end of the inlet pipe 13 extends to the inside of the mesh box.

[0034] The base plate 1 serves as the supporting base for the entire device, providing structural support and stability. A moving mechanism 7 and a limiting mechanism 8 are installed at the bottom, while the outer casing 2 is fixed at the top, integrating functional modules. The outer casing 2 protects internal components from external impacts and also integrates a control module. The dry powder extinguishing agent storage tank 3 stores ultrafine dry powder extinguishing agent (particle size ≤ 5μm), achieving chemical suppression extinguishing through high-pressure release. A fixing mechanism 4 is installed at the top to ensure stable connection with the connecting mechanism 5, and a stabilizing ring 6 is installed on the outside to prevent the tank from shaking during transportation or firefighting. The liquid storage tank 10 stores extinguishing water, pressurized by a pump body 12. Afterwards, a high-pressure fine water mist is formed. A mesh box is installed on the inner side to filter impurities in the water and prevent clogging of the pump body 12 or the nozzle. An infusion pipe is set at the top to facilitate external water replenishment. The front liquid level gauge 11 displays the water level in real time to avoid interruption of fire fighting due to water shortage. The pump body 12 serves as the core power source, pressurizing the water in the storage tank 10 to a high-pressure state (usually ≥10MPa). Water is drawn from the mesh box through the inlet pipe 13 and delivered to the nozzle through the outlet pipe 14. The end of the inlet pipe 13 extends to the inside of the mesh box to ensure the intake of clean water. The outlet pipe 14 extends to the top of the outer box 2 and connects to the nozzle to form a fine water mist spray path.

[0035] The fixing mechanism 4 includes a mounting base 401. The mounting base 401 is fixedly installed on the top of the dry powder extinguishing agent storage tank 3. The top of the mounting base 401 has two mounting slots 402. A limit frame 403 is fixedly installed on the inner bottom wall of the mounting slot 402. A movable plate 404 extending above the mounting base 401 is slidably installed on the inner side of the limit frame 403. A locking block 405 is fixedly installed on one side of the movable plate 404. A fixing cylinder 406 is fixedly installed on the inner wall of one side of the mounting slot 402. A fixing cylinder 406 is fixedly installed on the inner side of the fixing cylinder 406. A telescopic spring 407 is fixedly connected to the movable plate 404. A wedge block 408 located below the telescopic spring 407 is fixedly installed on one side of the movable plate 404. A support block 409 is fixedly installed on the front side of the inner wall of the mounting groove 402. A U-shaped frame 410 that passes through the support block 409 and extends to the inner side of the mounting groove 402 is slidably installed on the front side of the mounting base 401. The U-shaped frame 410 is located outside the wedge block 408. A cylinder 411 that is slidably connected to the inner side of the wedge block 408 is rotatably connected to the inner side of the U-shaped frame 410.

[0036] The inner side of the mounting base 401 is provided with a circular hole that matches the discharge pipe 51. The fixing plate 52 is located above the mounting base 401. The mounting base 401 is connected to the inner top wall of the dry powder fire extinguishing agent storage tank 3. The inner side of the fixing plate 52 is provided with a slot that matches the locking block 405. The front side of the mounting base 401 is provided with a through hole that matches the U-shaped frame 410. The through hole is connected to the front side of the inner wall of the mounting groove 402. The outer side of the U-shaped frame 410 is provided with a protective sleeve. The locking blocks 405 on both sides are symmetrically distributed.

[0037] Mounting base 401 is fixed to the top of the dry powder tank, serving as the mounting base for the connecting mechanism 5. A circular hole is opened on the inner side to seal and connect with the discharge pipe 51 to prevent dry powder leakage. The locking block 405 is connected to the fixing plate 52. The locking block 405 is elastically extended and retracted by the telescopic spring 407 and engages with the slot of the fixing plate 52 to achieve quick fixation of the discharge pipe 51. The symmetrical distribution design enhances the connection stability and prevents the pipe from falling off during fire extinguishing. The U-shaped frame 410 and the wedge block 408 are connected by the cylinder 411 pressing the wedge block 408 when the U-shaped frame 410 is manually pushed, which drives the moving plate 404 to compress the telescopic spring 407, causing the locking block 405 to disengage from the fixing plate 52 for quick disassembly. The limiting frame 403 limits the sliding range of the moving plate 404 to prevent the locking block 405 from excessively extending and retracting, which could cause structural damage.

[0038] The connecting mechanism 5 includes a discharge pipe 51, which is movably installed inside the mounting base 401 and extends to the top of the outer box 2 at one end. Fixing plates 52 located inside the outer box 2 are fixedly installed on both the left and right sides of the discharge pipe 51. One end of the locking block 405 is engaged with the fixing plate 52.

[0039] Two push handles are fixedly installed on the right side of the outer box 2. A circular perforation is opened on the inner top wall of the outer box 2. The diameter of the circular perforation is larger than the diameter of the discharge pipe 51.

[0040] A pressure gauge is installed on the front side of the discharge pipe 51. The discharge pipe 51 transports dry powder from the storage tank 3 to the discharge connection nozzle on the top of the outer box 2, which works in conjunction with the fine water mist system to extinguish the fire.

[0041] The moving mechanism 7 includes moving wheels 71. Four moving wheels 71 are fixedly installed on the bottom of the base plate 1. Limiting wheels 72 are fixedly installed on the opposite sides of the moving wheels 71 on both the front and rear sides.

[0042] The outer side of the limiting roller 72 has annularly distributed limiting grooves, which cooperate with the clamping plate 813 to fix the device.

[0043] The limiting mechanism 8 includes a mounting plate 801. A mounting plate 801 is fixedly mounted on the bottom of the base plate 1, located to the right of the limiting chuck 72. A through hole 802 is formed on the inner side of the mounting plate 801. A rotating push rod 803 is movably mounted through the through hole 802 and extends to the top of the base plate 1. A connecting plate 804 is fixedly mounted on the top of the rotating push rod 803. A handle 805 is fixedly mounted on the top of the connecting plate 804. A right-angle plate 806 is fixedly mounted on the top of the base plate 1, located below the connecting plate 804. A movable frame 807 is slidably mounted on the left side of the mounting plate 801, passing through the through hole 802 and extending to its right side. The outer side of the movable frame 807 is fixedly mounted... A rectangular plate 808 is fixedly installed and slidably connected to the inside of the perforation 802. A connecting spring 809 is fixedly installed on the right side of the rectangular plate 808 and fixedly connected to the right side of the inner wall of the perforation 802. A triangular block 810 is fixedly installed on the right side of the inner wall of the moving frame 807. Two guide frames 811 are fixedly installed on the inner top wall of the perforation 802 and located above the moving frame 807. A push block 812 that is attached to the top of the triangular block 810 is slidably installed between the inner sides of the two guide frames 811. The bottom end of the rotating push rod 803 is attached to the top of the push block 812. A locking plate 813 that is engaged with the limiting locking wheel 72 is fixedly installed on the left side of the moving frame 807.

[0044] The top of the triangular block 810 is inclined, the bottom of the push block 812 is inclined, the inner side of the mounting plate 801 is provided with a limiting hole that matches the moving frame 807, the limiting hole is connected to the inner wall of the through hole 802, the inner side of the base plate 1 is provided with a round hole that matches the rotating push rod 803, the outer side of the limiting chuck 72 is provided with a limiting groove that matches the chuck plate 813, the number of limiting grooves can be set according to requirements and are distributed in a ring at equal intervals.

[0045] Manually rotating handle 805 drives push rod 803 to press down push block 812, triggering plate 813 to engage with the limiting groove of limiting wheel 72. Right-angle plate 806 rotates push rod 803 and connecting plate 804 to move upward and reset.

[0046] Both the bottom of the push block 812 and the top of the triangular block 810 are designed with inclination, forming a wedge-shaped transmission structure. When the push rod 803 is rotated and pressed down, the inclined surface of the push block 812 pushes the triangular block 810 to move horizontally, causing the locking plate 813 to disengage from the limiting gear 72. The moving frame 807 is slidably installed on the inner side of the mounting plate 801, and the connecting spring 809 provides a reset force for fixation. When fixed, the spring 809 pulls the moving frame 807 to reset, causing the locking plate 813 to disengage from the limiting wheel 72. The end of the locking plate 813 is inserted into the limiting groove of the limiting wheel 72, and the position of the device is fixed by mechanical locking to prevent displacement during fire extinguishing.

[0047] During use, observe the level gauge 11 to ensure the water level in the storage tank 10 is sufficient. If insufficient, add water through the infusion pipe. Confirm that the pressure in the dry powder extinguishing agent storage tank 3 is normal (usually monitored by a pressure gauge) and that the dry powder is not clumped. Hold the push handle and push the device to the vicinity of the fire scene, ensuring the nozzle covers the target area. Pull the handle 805 to engage the locking plate 813 into the limiting groove of the limiting wheel 72. Check that the device is stable to prevent movement during firefighting. When the fire detector triggers a signal, the controller 16 automatically starts the pump body 12 and the dry powder release system, spraying out fine water mist and dry powder simultaneously to form a composite fire extinguishing effect. The fire can be started manually via controller 16. Observe the fire situation. If dry powder intervention is required, press the dry powder release button, adjust the nozzle angle to ensure that the extinguishing agent covers the fire source, and close the pump body 12 and dry powder valve via controller 16 after extinguishing the fire to stop spraying. Rotate handle 805 in the opposite direction to release the locking plate 813 on the limit wheel 72, and then the device can be moved. Fine water mist: There is less water stain, and no special treatment is required. Use a vacuum cleaner or soft brush to clean the residual dry powder to avoid corrosion of the equipment. Replenish the extinguishing agent by adding water to the liquid storage tank 10, and replace or replenish the dry powder in the dry powder extinguishing agent storage tank 3.

[0048] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0049] In summary, this high-efficiency fire extinguishing device combining high-pressure fine water mist and ultrafine dry powder, through the setting of a fixing mechanism 4 and a connecting mechanism 5, ensures the stable connection of the discharge pipe 51 by the mounting base 401 being engaged with the fixing plate 52 via the locking block 405, preventing dry powder leakage. When it is necessary to disassemble the discharge pipe 51, the U-shaped frame 410 is pulled to move outward of the mounting groove 402, and the cylinder 411 slides along the inclined surface of the wedge block 408, forcing the wedge block 408 to move outward, thereby driving the moving plate 404. Compression of the telescopic spring 407 causes the locking block 405 to disengage from the slot of the fixing plate 52. At this time, the discharge pipe 51 is unrestrained and can be easily removed from the mounting base 401, achieving the purpose of easy disassembly and replacement of the discharge pipe. By setting the moving mechanism 7 and the limiting mechanism 8, the moving wheel 71 facilitates the overall movement of the device. When the fire extinguishing operation is performed, the moving wheel 71 needs to be locked stably. Turning the handle 805 rotates the push rod 803 upward, the push block 812 loses pressure, and the connecting spring 809 pushes it. The moving frame 807 moves to the left, and the locking plate 813 engages with the limiting groove of the limiting wheel 72, fixing the limiting wheel 72 and preventing the moving wheel 71 from rotating. This achieves the purpose of having a stable structure. When the device needs to be moved, the handle 805 is turned, which drives the rotating push rod 803 to move downward through the connecting plate 804. This causes the connecting plate 804 to engage with the inside of the right-angle plate 806, pushing the push block 812 down along the guide frame 811. The push block 812 presses against the inclined surface of the triangular block 810, forcing the moving frame 807 to move to the right against the elastic force of the connecting spring 809. Finally, the locking plate 813 disengages from the limiting wheel 72, allowing the device to be moved. This further facilitates use and solves the problems of ultrafine dry powder being prone to moisture and clumping, and the ultrafine dry powder remaining in the device's spray tube after use easily clumping and clogging, making it impossible to quickly disassemble and replace the tube, affecting the use of the device. In addition, without a corresponding stable structure, the device cannot be stably stopped at a designated location and is prone to moving freely or being dragged.
