DETAILED DESCRIPTION

[0047] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0048] Embodiment 1:

[0049] This embodiment provides an indoor suspended mobile fire extinguishing device that can achieve efficient and accurate fire extinguishing and has good adaptability.

[0050] like Figure 1 As shown, the fire extinguishing device includes: an adjustable fire extinguishing unit and a suspended mobile unit; the suspended mobile unit is suspended on the indoor ceiling (separated from the indoor ceiling by a certain distance); the adjustable fire extinguishing unit is used to monitor the fire source (including identifying the fire source and determining the fire source location) and extinguish the fire; the adjustable fire extinguishing unit is installed on the suspended mobile unit, and the adjustable fire extinguishing unit can move along the suspended mobile unit in a plane to adjust the plane position; at the same time, the suspended mobile unit can adjust the height and angle of the adjustable fire extinguishing unit, so that the corresponding height position and angle adjustment can be made according to the fire source at any position in the room, so that the adjustable fire extinguishing unit can achieve precise fire extinguishing towards the fire source position.

[0051] Embodiment 2:

[0052] Based on the above-mentioned embodiment 1, the preferred structural forms of the suspended movable unit and the adjustable fire extinguishing unit are given.

[0053] like Figure 1 As shown, the suspended mobile unit includes: an electric telescopic rod 1 and a suspended track 5; the electric telescopic rod 1 adopts an existing structure, and its function is to drive the adjustable fire extinguishing unit to perform a linear displacement of a certain amplitude; the fixed end of the electric telescopic rod 1 is connected to the suspended track 5, and the telescopic end is connected to the adjustable fire extinguishing unit; thereby, the adjustable fire extinguishing unit can be driven to move up and down by the extension and retraction of the electric telescopic rod 1 to adjust the height position.

[0054] A track is arranged on the hanging track 5, and a roller is arranged in the track; the roller can move along the track. The top (i.e., the fixed end) of the electric telescopic rod 1 is connected to the roller. The function of the hanging track 5 is to drive the electric telescopic rod 1 to move through the roller, thereby driving the adjustable fire extinguishing device to achieve adjustment of different positions in the plane where the track is located.

[0055] As an example, Figure 3 and Figure 4 As shown, the suspended track 5 includes two mutually perpendicular tracks, namely, cross tracks.

[0056] Furthermore, in order to adjust the angle of the adjustable fire extinguishing unit, the top of the electric telescopic rod 1 is connected to the roller through a universal ball steering structure A2, and the bottom (i.e., the telescopic end) is connected to the adjustable fire extinguishing unit through a universal ball steering structure B15; the function of the universal ball steering structure A2 is to drive the entire electric telescopic rod 1 (and the adjustable fire extinguishing unit at its end) to rotate, and the function of the universal ball steering structure B15 at the bottom is to drive the adjustable fire extinguishing unit to rotate.

[0057] The universal ball steering structure A2 has the same structure as the universal ball steering structure B15. In order to realize automatic control of the fire extinguishing device, the universal ball steering structure A2 and the universal ball steering structure B15 not only provide a universal ball rotating joint, but also include a power source for driving (not shown in the figure). The power source can be controlled by an external control unit, thereby realizing automatic control of the rotation angle.

[0058] On this basis, further, an electric telescopic rod fixing structure 6 is provided on the track, which is used to limit the electric telescopic rod 1 (i.e. fix the position). For example, an electric telescopic rod fixing structure 6 is provided at the end of a track in a cross track. When the fire extinguishing device is in a monitoring state, the electric telescopic rod 1 rotates around the universal ball steering structure A2 at its upper end to a horizontal state, and its telescopic end is limited by the electric telescopic rod fixing structure 6. As an example, the electric telescopic rod fixing structure 6 is a semicircular opening slot that can be opened and closed automatically, and the telescopic end of the electric telescopic rod 1 can be stuck in the slot; when a fire is detected and the adjustable fire extinguishing unit needs to be adjusted in position, the electric telescopic rod fixing structure 6 automatically opens to release the limit on the electric telescopic rod 1.

[0059] like Figure 2 As shown, the adjustable fire extinguishing device includes: a hanging base 16 and a depth camera 7 (one or more), an infrared camera 8 (one or more), a hollow telescopic structure 10, a mechanical claw 11, a suction cup 12 and a nozzle 13 arranged on the hanging base 16; the telescopic end of the electric telescopic rod 1 is connected to the hanging base 16 through a universal ball steering structure B15, the depth camera 7 and the infrared camera 8 are fixed on the hanging base 16, the depth camera 7 is used to determine the spatial position of the fire source, and the infrared camera 8 is used to monitor and identify the infrared characteristics of the fire source. The depth camera 7 and the infrared camera 8 are electrically connected to the external control unit for signal transmission; the mechanical arm base 14 is fixed on the hanging base 16, and a mechanical arm bracket 9 is fixed on the mechanical arm base 14, and the hollow telescopic structure 10 is connected to the mechanical arm bracket 9 (such as the rear end of the hollow telescopic structure 10 is connected to the mechanical arm bracket 9 as a fixed end, and the front end can be telescopic relative to the fixed end).

[0060] The front end of the hollow telescopic structure 10 is connected to a mechanical claw 11 and a suction cup 12, wherein a nozzle 13 is arranged at the center of the suction cup 12. The hollow telescopic structure 10 has an automatic telescopic function, which can drive the mechanical claw 11, the suction cup 12, and the nozzle 13 to achieve telescopic expansion. The function of the mechanical claw 11 and the suction cup 12 is to open the closed structure through the mechanical claw 11 and the suction cup 12 to achieve precise fire extinguishing when the fire source in the closed area (such as a cabinet or a drawer) cannot be directly extinguished by the nozzle 13, thereby achieving accurate fire extinguishing.

[0061] One end of the water pipe used for fire extinguishing is wound around the water pipe winding disc 3, and the other end passes through the hollow telescopic structure 10 and is connected to the nozzle 13.

[0062] The water pipe winding disc 3 is arranged on the hanging track 5; in this example, the water pipe winding disc 3 adopts a fully automatic separation type water pipe winding disc (i.e., it can realize the automatic retraction and release of the water pipe and the separate winding of the water pipe); brackets are arranged at both ends of the axial direction of the water pipe winding disc 3, and the brackets are fixed on the platform of the hanging track 5. A rotating shaft is arranged between the two brackets, and the water pipe winding disc 3 is coaxially sleeved on the outside of the rotating shaft. The rotating shaft is driven by the rotating motor at the end of the bracket, thereby driving the water pipe winding disc 3 to rotate around its own axis to realize the retraction and release of the water pipe; the rotating motor can be controlled by an external control unit, thereby realizing the automatic retraction and release of the water pipe. A spiral groove is arranged on the surface of the water pipe winding disc 3 for separate storage of the water pipe (i.e., the water pipe is single-layered and separately wound on the water pipe winding disc 3).

[0063] Embodiment 3:

[0064] On the basis of the above-mentioned embodiment 2, further, a water pipe guide wheel 4 is provided on the hanging track 5, and the water pipe on the water pipe winding plate 3 passes through the water pipe guide wheel 4 and further passes through the hollow telescopic structure 10 to be connected with the nozzle 13; the water pipe guide wheel 4 is provided to guide the water pipe so that it is installed in the direction of the adjustable fire extinguishing device. The angle of the water pipe guide wheel 4 itself is adjustable, so that the angle can be adjusted according to the adjustment of the position and angle of the adjustable fire extinguishing device.

[0065] Specifically: the water pipe guide wheel 4 is a groove wheel structure, which is installed on a turntable through a steering shaft bracket (the steering shaft is the central axis of the water pipe guide wheel 4), and the turntable is supported on a base. The turntable can rotate (such as driven by a motor), thereby driving the water pipe guide wheel 4 and its steering shaft bracket to rotate as a whole, so as to adjust the angle of the water pipe guide wheel 4; the base is connected to the roller in the suspended track 5. When the roller in the suspended track 5 drives the adjustable fire extinguishing unit to move (such as when automatic control is adopted, the roller is driven to move in the track by a power unit controlled by an external control unit, and the power unit is not shown in the figure), the water pipe connected to the nozzle 13 also needs to be extended or contracted by a corresponding length. In order to make the movement more efficient, the water pipe winding disk 3 extends or contracts the water pipe by a corresponding amplitude, and the water pipe guide wheel 4 cooperates to move the position and adjust the angle.

[0066] Thus, the suspended track 5 can drive the electric telescopic rod 1 through the roller and then drive the adjustable fire extinguishing unit to move in the track, thereby realizing adjustment of different positions of the plane, and adjusting the angle of the water pipe guide wheel 4 so that the connection direction of the guide water pipe matches the moving position of the roller.

[0067] The working principle of the fire extinguishing device is:

[0068] The fire extinguishing device is usually in a monitoring state, the electric telescopic rod 1 does not extend, and rotates to a horizontal state, and the end is limited by the electric telescopic rod fixing structure 6; at this time, the electric telescopic rod 1 is in a horizontal state and is located below the hanging track 5; the angle of the hanging base 16 can be adjusted through the universal ball steering structure B15, and then the angle of the infrared camera 8 and the depth camera 7 can be adjusted (usually with their lenses facing downward); the infrared camera 8 in the adjustable fire extinguishing unit is in a normally open state, monitoring the temperature changes in the room, and sending the monitoring information to the external control unit in real time to determine whether a fire has occurred. The external control unit pre-stores the indoor space information of the room where the fire extinguishing device is located.

[0069] When a fire source is found, the infrared camera 8 transmits the infrared heat signal to the computer, and the external control unit controls the depth camera 7 to turn on. The depth camera 7 captures the three-dimensional point cloud signal of the fire source and transmits it back to the external control unit. The external control unit determines the spatial position of the fire source and determines the three-dimensional coordinates of the fire source position based on the pre-stored indoor space information; then the moving route of the roller in the hanging track 5 and the telescopic distance of the electric telescopic rod 1 are planned so that the height and plane distance of the adjustable fire extinguishing unit from the fire source reach the set distance. During the movement of the roller and the telescopic extension of the electric telescopic rod 1, the water pipe winding disc 3 rotates at a corresponding angle under the control of the external control unit to retract and release the water pipe. At the same time, through the cooperation of the water pipe guide wheel 4, the water pipe is prevented from being entangled with the electric telescopic rod 1 and the adjustable fire extinguishing unit.

[0070] When the adjustable fire extinguishing unit is driven by the roller and the electric telescopic rod 1 to reach the designed distance from the fire source, the angle of the adjustable fire extinguishing unit is adjusted by the universal ball steering structure B15 at the bottom end of the electric telescopic rod 1 to gradually eliminate the angular error between the nozzle 13 and the fire source, so that the nozzle 13 faces the fire source, and then the water pump connected to the water pipe is started to accurately extinguish the fire source.

[0071] In addition, the suction cup 12 or the mechanical claw 11 or the combination of the two is determined according to the structural characteristics and space conditions of the location of the fire source. If the fire source is inside the cabinet and the cabinet door can be opened, the suction cup 12 is used to directly suck the cabinet door, and then the cabinet door is opened by moving the adjustable fire extinguishing unit. If the fire source is in the drawer and the drawer has a handle, the mechanical claw 11 is used to hold the handle and open the cabinet door. For complex closed structures, the suction cup 12 and the mechanical claw 11 can also be used to open the closed structure.

[0072] When the indoor space is large, several of the above-mentioned fire extinguishing devices can be installed indoors according to usage requirements.

[0073] The fire extinguishing device has the following advantages:

[0074] (1) High-sensitivity fire identification and precise fire extinguishing: The mobile fire extinguishing device has extremely high fire identification sensitivity (the conventional automatic fire extinguishing system relies on smoke alarms, and the fire is already quite large when it is identified. This solution uses infrared to identify the fire source at the first time), and can achieve point-to-point precise extinguishing, avoiding secondary damage to areas outside the fire source during the fire extinguishing process, especially water damage. Through precise positioning and fire extinguishing, the device can effectively curb the spread of fire in the early stages of the fire.

[0075] (2) Height adjustable and highly adaptable: The device uses an electric telescopic rod and a suspended track to adjust the height and direction of the fire extinguishing device as needed, ensuring that fires at different locations and heights can be accurately extinguished. The fire extinguishing robot arm is equipped with a suction cup and a mechanical claw, which can flexibly deal with objects of different materials and shapes. It is particularly suitable for extinguishing fires in enclosed spaces and can function efficiently in complex environments.

[0076] (3) Adapting to complex environments and low visibility: Indoor fires usually occur in small and complex spaces, and visibility is low when a fire occurs. To address this challenge, the device is equipped with a suspended mobile unit to ensure smooth movement and efficient operation when extinguishing the fire. At the same time, the device is also equipped with an infrared camera and a depth camera to avoid delays in firefighting operations due to limited vision or complex environments, thereby improving firefighting efficiency.

[0077] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made on the basis of the present invention. Therefore, these modifications or improvements made on the basis of not departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
