[0003] In the prior art, existing automatic tracking jet fire extinguishing devices are mostly based on pyroelectric sensors and CCD or CMOS image sensors to detect and track flames. Pyroelectric sensors are easily affected by light, heat, wind, etc., and only have one-time positioning and do not have the ability of real-time tracking. Image sensors can only detect visible light and near-infrared images, and have poor anti-interference capabilities, especially sensitive to the scattering of sunlight, and cannot cope with outdoor or complex working environments. Therefore, we propose an automatic tracking jet fire extinguishing device based on infrared thermal imaging. Utility Model Content

Image sensors can only detect visible light and near-infrared images, have poor anti-interference capabilities, and are particularly sensitive to the scattering of sunlight, and are unable to cope with outdoor or complex working environments.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0011] As a preferred solution of the utility model, a driving motor is installed inside the base, and a rotating shaft extends from the right side of the outer periphery of the rotating ring and is fixedly connected to the output end of the driving motor.

[0012] The technical effect of adopting the above further solution is: the driving motor can drive the rotating ring to rotate, thereby adjusting the angle of the second water supply pipe in the adjustment groove, so as to facilitate the infrared thermal imaging sensor and the ordinary visible light CCD image sensor to track the target.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

An arc-shaped adjusting groove 4 is opened on the front of the base 1, and a second water supply pipe 5 connected to the first water supply pipe 2 is installed inside the adjusting groove 4 and extends to the front, and then a mounting collar 6 with an inner diameter consistent with the outer diameter of the second water supply pipe 5 is sleeved on the periphery of the second water supply pipe 5 near the front, and a square mounting seat 7 is installed on the periphery of the mounting collar 6 and near the left side, and then an infrared thermal imaging sensor 8 is installed on the top of the mounting seat 7 near the right side, and then a common visible light CCD image sensor 9 is installed on the top of the mounting seat 7 near the left side.

[0025] Example 2

[0026] like Figure 1-3 As shown, the interior of the second water supply pipe 5 extends to the front and a fire extinguishing nozzle 51 is installed. The fire extinguishing nozzle 51 is slidably connected to the second water supply pipe 5 and can effectively spray fire water to extinguish fire.

[0027] A holder 61 is installed on the outer periphery of the mounting ring 6 near the right side, and an electric push rod 62 is installed on the front side of the holder 61. The output end of the electric push rod 62 is fixedly connected to the fire extinguishing nozzle 51. The electric push rod 62 can adjust the length of the fire extinguishing nozzle 51 to facilitate fire extinguishing work.

[0028] A square fixing seat 63 is installed near the top of the outer periphery of the mounting collar 6, and a trapezoidal processor 64 is installed on the top of the fixing seat 63. The processor 64 can be connected to a remote fire alarm platform to facilitate fire handling.

[0029] A rotating collar 52 having an inner diameter consistent with the outer diameter of the second water supply pipe 5 is sleeved on the periphery of the second water supply pipe 5 near the back side, a bearing 53 is installed on the left side of the rotating collar 52 and on the inner wall of the adjusting groove 4, a rotating shaft extends from the left side of the periphery of the rotating collar 52 and is rotatably connected to the bearing 53, and the bearing 53 facilitates the rotation of the rotating collar 52.

[0030] A driving motor 54 is installed inside the base 1 , and a rotating shaft extends from the right side of the outer periphery of the rotating ring 52 and is fixedly connected to the output end of the driving motor 54 . The driving motor 54 can effectively drive the rotating ring 52 to rotate, thereby adjusting the angle.

[0031] The working process of the utility model is as follows: when using an automatic tracking jet fire extinguishing device based on infrared thermal imaging to extinguish a fire, first, the infrared thermal imaging sensor 8 and the ordinary visible light CCD image sensor 9 monitor the monitoring point in real time, and once a heat source appears within the monitoring range, the processor 64 transmits the data to the remote fire alarm platform, and at the same time controls the driving motor 54 to drive the rotating ring 52 to adjust the angle of the fire extinguishing nozzle 51 in the adjusting groove 4, and when adjusting the angle, the bearing 53 also maintains the stability of the rotating ring 52, and as the angle is adjusted, the infrared thermal imaging sensor 9 The device 8 and the ordinary visible light CCD image sensor 9 track the heat source in real time. After the fire extinguishing nozzle 51 is aimed at the heat source, the fire extinguishing nozzle 51 is pushed out by the electric push rod 62. After being pushed out, the remote fire water is started, and the fire water passes through the first water supply pipe 2 and the second water supply pipe 5, and finally sprayed to the heat source through the fire extinguishing nozzle 51. Before the fire starts, the heat source is cooled down, thereby killing the fire in its early stage. The utility model can effectively solve the problem that the existing automatic tracking jet fire extinguishing device does not have real-time tracking and has poor anti-interference ability through design, thereby effectively achieving rapid positioning and tracking of the fire source and eliminating interference.
