[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0018] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides an intelligent temperature-sensing fire extinguishing device, including a bracket 1. Two sets of clamps 2 are installed on the front of the bracket 1. A high-pressure storage tank 3 is installed on the inner wall of the clamps 2. An infrared temperature sensor 12 is installed on the upper outer wall of the bracket 1. A power supply module 13 is installed on the back of the bracket 1. An electromagnetic three-way valve 4 is installed at the bottom of the high-pressure storage tank 3. The top of the electromagnetic three-way valve 4 is connected to the inside of the high-pressure storage tank 3. One end of the electromagnetic three-way valve 4 is fixedly connected to a discharge pipe 41. The bottom end of the discharge pipe 41 is fixedly connected to a connector 42. Multiple spray nozzles 43 are fixedly connected to the side wall of the connector 42. The other end of the electromagnetic three-way valve 4 is fixedly connected to a discharge pipe 44. A directional spray mechanism 5 is installed on the bottom surface of the discharge pipe 44.
[0019] The specific settings and functions of this embodiment are described below. The clamp 2 tightly fits against the outer wall of the high-pressure storage tank 3, firmly fixing it to the front of the bracket 1. This prevents the high-pressure storage tank 3 from shifting due to vibration or installation tilt, ensuring the stability of extinguishing agent storage and output. The high-pressure storage tank 3 stores the extinguishing agent at high pressure, providing a stable pressure source for the spraying process and ensuring efficient delivery of the extinguishing agent to the spraying components via subsequent pipelines. The extinguishing agent is accessed through the connection between the electromagnetic three-way valve 4 and the high-pressure storage tank 3. Electromagnetic control switches the connection status with discharge pipe 1 41 and discharge pipe 2 44, providing a structural basis for both full-area coverage and directional precision spraying modes. Discharge pipe 1 41 guides the extinguishing agent into the communicating vessel 42. 2. The extinguishing agent is evenly distributed to multiple nozzles 43. Through the distributed layout of multiple nozzles, a wide-area full-area spray coverage is formed, which is suitable for open spaces or multi-point hidden danger scenarios, and can quickly suppress the spread of fire. The extinguishing agent discharged by the electromagnetic three-way valve 4 is accurately delivered to the directional spraying mechanism 5 through the discharge pipe 2 44, ensuring the stability of pressure and flow during directional spraying. The infrared temperature sensor 12 collects ambient temperature data in real time, providing core sensing signals for fire identification. Its plug-in connection design with the controller 11 facilitates later calibration and replacement. The power supply module 13 provides continuous and stable power to the controller 11, electromagnetic three-way valve 4, infrared temperature sensor 12 and other electrical control components, ensuring the reliability of the device in all-weather standby and emergency start.
[0020] Example 2: Figure 1 - Figure 4As shown, the directional spraying mechanism 5 includes a servo motor 51, a connecting sleeve 52, and a spray pipe 53. The connecting sleeve 52 is located below the servo motor 51 and is sleeved on the outer wall of the middle part of the spray pipe 53. The top end of the spray pipe 53 is rotatably connected to the inner wall of the end of the discharge pipe 44. The servo motor 51 is fixedly installed on the top surface of the connecting sleeve 52. A pulley assembly 55 is connected between the output shaft end of the servo motor 51 and the outer wall of the spray pipe 53. A mounting plate 54 is fixedly connected to the back of the connecting sleeve 52. A controller 11 is installed on the upper outer wall of the bracket 1. An infrared temperature sensor 12 is plugged into the end of the controller 11. The controller 11 is electrically connected to the power supply module 13. Multiple mounting plates 14 are installed on the back of the bracket 1.
[0021] The overall effect of this embodiment is as follows: the directional spray mechanism 5, as the core execution component for precise fire extinguishing, achieves adjustable spray angle through the coordinated action of the servo motor 51, the pulley assembly 55, and the spray pipe 53. The servo motor 51 provides power, which drives the spray pipe 53 to rotate around the end of the discharge pipe 44 via the pulley assembly 55, achieving 360° spray angle adjustment. The connecting sleeve 52 integrates and fixes the servo motor 51 and the spray pipe 53. The mounting plate 54 firmly connects the entire mechanism to the bracket 1, ensuring structural rigidity during rotation. The controller 11, as the intelligent control core of the device, receives temperature data from the infrared temperature sensor 12, judges the fire risk through a built-in algorithm, and then controls the path switching of the electromagnetic three-way valve 4 and the start, stop, and speed of the servo motor 51. At the same time, it is electrically connected to the power supply module 13 to achieve power distribution and energy consumption management. Its plug-in design with the infrared temperature sensor 12 simplifies the assembly and maintenance process. The mounting plate 14, through a multi-group distributed layout design, provides fixed points for different installation scenarios such as walls and equipment for the bracket 1, improving the installation adaptability of the device.
[0022] The usage and working principle of this device: The device is fixed by means of hanging, wall mounting or other methods through the mounting plate 14 on the back of the bracket 1. The high pressure storage tank 3 is fixed on the bracket 1 by the clamp 2, ensuring that the spray head 43 is facing the full coverage area and the directional spray mechanism 5 is facing the potential precise fire extinguishing area. Sensing Phase: Infrared temperature sensor 12 collects ambient temperature data in real time and transmits it to controller 11. Controller 11 analyzes the temperature value and temperature rise rate through algorithms to determine whether the fire trigger threshold has been reached. Decision Phase: If a fire is detected, controller 11 controls the electromagnetic three-way valve 4 to switch the connection path based on fire source monitoring data (such as range and location). When the fire source range is wide, discharge pipe one 41 is connected; when the fire source is concentrated or located in a confined space, discharge pipe two 44 is connected. Execution Phase: When discharge pipe one 41 is connected, the extinguishing agent in the high-pressure storage tank 3 flows through discharge pipe one... 41 enters the communicating vessel 42 and forms a full-area spray through multiple nozzles 43; when the discharge pipe 2 is connected to the discharge pipe 44, the controller 11 synchronously starts the servo motor 51, which drives the spray pipe 53 to rotate to the direction of the fire source through the pulley assembly 55, and the extinguishing agent is sprayed in a directional and precise manner through the discharge pipe 2 44 and the spray pipe 53; feedback stage: during the fire extinguishing process, the infrared temperature sensor 12 continuously feeds back temperature data, and the controller 11 judges the fire extinguishing effect according to the temperature change, until the temperature drops to a safe range and then closes the electromagnetic three-way valve 4 and issues an alarm signal to prompt manual inspection.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
