While some mobile fire extinguishing devices are mobile, their fire detection accuracy is insufficient, making it difficult to accurately identify the location of early-stage fires and prone to accidental spraying, thus affecting reliability. Furthermore, the low integration of the extinguishing agent delivery and spray gun drive systems results in bulky equipment that is inconvenient to maintain and cannot meet the requirements for deployment in compact spaces.

[0003] To address the aforementioned problems, this utility model document proposes a mobile automatic tracking and positioning jet fire extinguishing device. Utility Model Content

[0004] This utility model provides a mobile automatic tracking and positioning jet fire extinguishing device, which solves the shortcomings of some existing mobile fire extinguishing devices that, although mobile, have insufficient fire detection accuracy, making it difficult to accurately identify the location of early fires, are prone to accidental spraying, affecting reliability, and have low integration of the fire extinguishing agent delivery and spray gun drive system, resulting in large equipment size, inconvenient maintenance, and inability to meet the requirements of compact space deployment.

[0005] This utility model provides the following technical solution: A mobile automatic tracking and positioning jet fire extinguishing device, comprising: The mobile container has lockable maintenance doors that are rotatably installed at both sides of the container opening. Four casters are fixedly installed at the four corners of the bottom of the mobile container. A hollow rotating rod is rotatably installed on the top of the mobile container via bearings. A U-shaped mounting bracket is fixedly installed along the upper edge of the outer wall of the hollow rotating rod. An adjustable tilting rotating block is installed inside the U-shaped mounting bracket. A spray gun is fixedly installed through the bottom of the rotating block. A fire extinguishing agent tank and a multi-stage centrifugal pump are fixed to the bottom of the inner wall of the mobile container via bolts.

[0006] In one possible design, a hollow gear is concentrically fixed along the lower edge of the outer wall of the hollow rotating rod, and a solid gear meshing with the hollow gear is rotatably mounted on the top of the movable box via a bearing. The hollow gear and the solid gear are covered by the same rectangular mounting bracket with heat dissipation holes on both sides. A drive motor I is fixedly mounted on the top of the rectangular mounting bracket, and the output shaft of the drive motor I passes through the inner wall of the rectangular mounting bracket and is fixedly connected to the center of the top of the solid gear.

[0007] In one possible design, the same transmission rod is mounted on both ends of the inner wall of the U-shaped mounting bracket via bearings. The inner wall of the through hole in the center of the rotating block is fixedly connected to the outer wall of the transmission rod. A drive motor II is fixedly mounted on the outer wall of the U-shaped mounting bracket. The output shaft of the drive motor II passes through the inner wall of the U-shaped mounting bracket and is fixedly connected to one end of the transmission rod via a coupling.

[0008] In one possible design, the input end of the multi-stage centrifugal pump is connected to the lower edge of the inner wall of the extinguishing agent tank through the same flexible hose, and the output end of the multi-stage centrifugal pump is connected to the input end of the spray gun through a flexible hose running through the cavity of the hollow rotating rod.

[0009] In one possible design, a pen-shaped camera is fixedly attached to the top of the rotating block, and the other end of the transmission rod is fixedly attached to the outer wall of the U-shaped mounting bracket with an infrared-ultraviolet composite sensor acquisition terminal.

[0010] In one possible design, an audible and visual alarm is fixedly installed on the top of the mobile box, and a control terminal with a built-in AI algorithm is fixedly installed on one side of the inner wall of the mobile box.

[0011] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0012] The working principle and usage process of this technical solution are as follows: In use, the device monitors the protection range around the clock through an infrared-ultraviolet composite sensor acquisition terminal, while a pen-shaped camera simultaneously captures on-site images. Both data are transmitted in real-time to a control terminal with a built-in AI algorithm. Upon receiving the sensor and image data, the control terminal analyzes and identifies early-stage fires using the AI ​​algorithm, accurately calculating the fire's spatial coordinates. Simultaneously, it triggers an anti-false-spray verification mechanism to avoid misjudgments. Once the fire is confirmed, the control terminal activates an active audible and visual alarm to issue a warning, and simultaneously starts a multi-stage centrifugal pump to extract extinguishing agent from the extinguishing agent tank. The control terminal controls drive motor I via CAN bus commands, causing the solid gear to mesh with the hollow gear, rotating the hollow rotating rod horizontally and adjusting the spray gun's horizontal direction. Simultaneously, drive motor II rotates, tilting the rotating block via a transmission rod to adjust the spray gun's spray angle, achieving precise alignment of the fire's coordinates. The extinguishing agent, pressurized by the multi-stage centrifugal pump, is delivered to the spray gun through a hose inside the hollow rotating rod, providing precise jet extinguishing within a certain protection radius.

[0013] This utility model has the following beneficial effects: This invention combines infrared and ultraviolet composite sensing technology with AI algorithms and a pen-shaped camera to accurately determine the coordinates of early fires, providing 24 / 7 monitoring without blind spots and effectively shortening the time for fire identification and response. Dual drive motors control the horizontal rotation and tilt angle of the spray gun, and pressure adjustment allows for adjustable spraying accuracy. An internal anti-misoperation mechanism reduces the risk of misoperation.

[0014] The device in this utility model is equipped with casters at the bottom, which can be placed anywhere and is suitable for various scenarios such as warehouses, repair sheds, and electric vehicle sheds, making it highly practical. The active sound and light alarm can issue fire warnings in real time to remind on-site personnel to evacuate. The overall structure is compact and can effectively curb the early spread of fire.

[0015] This utility model adopts CAN bus technology, supports all functions of on-site operation, and can modify the equipment address and spray parameters; it can be equipped with a backup power supply, and can still be used normally in the absence of power. The mobile box is equipped with lockable maintenance doors on both sides, which facilitates the maintenance of internal components such as fire extinguishing agent tanks and pumps.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0021] In one embodiment: Please refer to Figure 1-5 A jet fire extinguishing device, comprising: Mobile box 1 is a rectangular structure with maintenance doors 2 installed on both sides of the box opening via hinges. The maintenance doors 2 are equipped with locks, which can protect the internal components when closed and facilitate later maintenance operations when opened. The four corners of the bottom of the mobile box 1 are fixed with casters 3 by bolts, which can push the device to move and place it on a flat surface to meet the adjustment needs of different control areas. The top of the mobile box 1 has reserved installation holes, and a hollow rotating rod 4 is installed by rotating it through a deep groove ball bearing. The upper edge of the outer wall of the hollow rotating rod 4 is fixed with a U-shaped mounting bracket 9 by welding, and the lower edge of the outer wall is connected with a key to fix a concentric hollow gear 5.

[0022] A solid gear 6 is mounted on the top of the mobile box 1 at the position corresponding to the hollow gear 5 via a bearing. The solid gear 6 and the hollow gear 5 mesh with each other. A rectangular mounting bracket 7 is installed on the outside of both. Heat dissipation holes are opened on both sides of the rectangular mounting bracket 7. The top of the bracket is fixed with a drive motor I8 by bolts. The drive motor I8 is an asynchronous motor. Its output shaft passes through the inner wall of the rectangular mounting bracket 7 and is fixedly connected to the center of the top of the solid gear 6 by a flat key. This ensures that when the drive motor I8 is running, it can drive the solid gear 6 to rotate synchronously, thereby driving the hollow gear 5 and the hollow rotating rod 4 to rotate horizontally.

[0023] The transmission rods 10 are mounted on both ends of the inner wall of the U-shaped mounting bracket 9 via bearings. A through hole is opened in the center of the rotating block 11. The inner wall of the through hole is fixed to the outer wall of the transmission rod 10 by welding, so that the rotating block 11 can rotate synchronously with the transmission rod 10 to adjust the tilt. The drive motor II 12 is fixed to the outer wall of the U-shaped mounting bracket 9 by bolts. The drive motor II 12 is an asynchronous motor. Its output shaft passes through the inner wall of the U-shaped mounting bracket 9 and is fixed to one end of the transmission rod 10 by a coupling. The other end of the transmission rod 10 passes through the outer wall of the U-shaped mounting bracket 9 and is fixed to the infrared-ultraviolet composite sensor acquisition terminal 17 by threads. A copper alloy spray gun 13 is fixed through the bottom end of the rotating block 11, and a pen-shaped camera 16 is fixed through the top end. The acquisition direction of the pen-shaped camera 16 and the infrared-ultraviolet composite sensor acquisition terminal 17 is consistent with the spraying direction of the spray gun 13. The infrared-ultraviolet composite sensing acquisition terminal 17 integrates an infrared sensor and an ultraviolet sensor. The infrared sensor detects infrared radiation of a specific band generated by the fire, while the ultraviolet sensor captures the ultraviolet light signal released when the flame is burning. When a signal that matches the characteristics of a fire is detected, the terminal converts the physical signal collected by the sensor into an electrical signal and transmits it to the control terminal 19 in real time. This signal works in conjunction with the image data from the pen-shaped camera 16 to provide sensing support for the AI ​​algorithm to accurately determine the location of the fire and identify early fire conditions.

[0024] The bottom of the inner wall of the mobile box 1 is fixed with bolts to the extinguishing agent tank 14 and the multi-stage centrifugal pump 15. The extinguishing agent tank 14 stores the extinguishing medium. The input end of the multi-stage centrifugal pump 15 is connected to the lower edge of the inner wall of the extinguishing agent tank 14 through a hose, and the output end is connected to the input end of the spray gun 13 through a hose. The connecting hose passes through the cavity of the hollow rotating rod 4. After the multi-stage centrifugal pump 15 is powered on, the motor drives the pump shaft and multi-stage impellers to rotate at high speed. The rotation of the impellers generates centrifugal force, which draws the extinguishing medium in the extinguishing agent tank 14 into the pump chamber. Under the step-by-step pressurization of the multi-stage impellers, the pressure of the extinguishing medium gradually increases to the range required for operation. Then, it is delivered to the spray gun 13 through the hose at the output end, providing a stable pressure source for jet extinguishing and ensuring that the extinguishing medium can cover the fire area with the set protection radius.

[0025] The top of the mobile box 1 is fixed with bolts to the sound and light alarm 18. When the control terminal 19 confirms the fire, it sends a trigger signal to the sound and light alarm 18. After the internal sound unit (buzzer) of the alarm is powered on, it produces a continuous or intermittent warning sound. At the same time, the light unit (LED light group) is powered on and flashes rapidly. Through the dual warning of sound and light, the personnel on site are reminded to evacuate in time and the fire signal is transmitted simultaneously.

[0026] The control terminal 19 is fixed to one side of the inner wall of the mobile box 1 with bolts. The control terminal 19 has a built-in AI algorithm and an integrated CAN bus control module, which supports the realization of on-site operation functions. When wiring, the wire of the drive motor I 8 passes through the bottom of the rectangular mounting bracket 7 and then through the top wall of the mobile box 1 to enter the box. It is connected to the output interface of the control terminal 19 through a terminal. The wire of the audible and visual alarm 18 passes directly through the top wall of the mobile box 1 to enter the box and is connected to the alarm interface of the control terminal 19. The wire of the multi-stage centrifugal pump 15 extends directly to the power interface of the control terminal 19 and is fixed with a terminal. The wire of the drive motor II 12 passes through the bottom of the U-shaped mounting bracket 9 and converges with the wires of the pen-shaped camera 16 and the infrared and ultraviolet composite sensor acquisition terminal 17. They pass through the cavity of the hollow rotating rod 4 and enter the mobile box 1, respectively connecting to the corresponding control interface and signal interface of the control terminal 19. All wiring points are wrapped with insulating tape for protection to ensure stable and reliable circuit connection.

[0027] In practical use, the infrared-ultraviolet composite sensor acquisition terminal 17 continuously monitors the surrounding environment, while the pen-shaped camera 16 simultaneously acquires image information. Both transmit the data to the control terminal 19 in real time. The control terminal 19 analyzes the data using a built-in AI algorithm, identifies the fire, determines its coordinates, and performs an anti-misfire calibration. After confirming the fire, the control terminal 19 triggers the audible and visual alarm 18 to issue a warning and simultaneously starts the multi-stage centrifugal pump 15 to extract the extinguishing medium from the extinguishing agent tank 14. After pressurization, the medium is delivered to the spray gun 13 through a hose. During this process, the control terminal 19... The CAN bus outputs commands to control the drive motor I8 to operate, which drives the solid gear 6 to mesh with the hollow gear 5 to rotate. This causes the hollow rotating rod 4 to adjust the spray gun 13 to a horizontal position. At the same time, it controls the drive motor II12 to operate, which drives the rotating block 11 to rotate through the transmission rod 10, adjusting the tilt angle of the spray gun 13 until the spray gun 13 is aligned with the fire coordinates. The extinguishing medium is then ejected through the spray gun 13 to extinguish the fire. The device can modify the water cannon address and spray accuracy parameters through on-site operation. In the absence of power supply, an external backup power supply can be connected to power all electrical components to ensure the normal operation of the device.

[0028] This application can be used for fire fighting, or in other fields applicable to this application.

[0029] In another embodiment: A mobile automatic tracking and positioning jet fire extinguishing device is used in the field of fire protection equipment. The structure of this embodiment is basically the same as that of the aforementioned embodiments, except that: Please refer to Figure 1-2 Short screws are fixedly installed at the four corners of the bottom of the mobile box 1. Corresponding hollow support legs are threaded onto the short screws. After the mobile box 1 is moved to the designated position, the four hollow support legs are rotated to make them all make stable contact with the ground, which helps to avoid accidental movement.
