Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and more specifically to an automatic positioning fire monitor. Background Technology

[0002] Existing fire-fighting equipment often has limitations in locating and extinguishing fires. Traditional fire monitors mostly require manual operation, making it difficult to quickly and accurately locate the fire source when facing fires in large venues or complex environments, resulting in low fire-fighting efficiency and further expansion of fire losses.

[0003] With the development of technology, although some fire-fighting equipment with automatic functions has emerged, there are still shortcomings in the precise location of fires and the automatic adjustment of fire monitors. For example, some sensor-based fire monitors are easily affected by external interference, leading to false alarms or inaccurate positioning; while some image recognition-based fire-fighting equipment struggles to reliably locate fire sources and automatically control fire monitors when dealing with complex scenes and strong light interference. Therefore, how to provide a fire monitor that can quickly and accurately locate fires automatically is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] See Figure 1-5 This utility model discloses an automatic positioning fire monitor, comprising:

[0028] Mounting base plate 2, which has a water inlet hole. One end of mounting base plate 2 is connected to water inlet base 3, which has a water inlet channel. The end of water inlet base 3 away from mounting base plate 2 is connected to water supply pipe 14, and the end of water supply pipe 14 away from water inlet base 3 is connected to water outlet pipe 12. The end of water outlet pipe 12 away from water supply pipe 14 is connected to water spray pipe 10, which has a regulating valve. The water inlet hole, water inlet channel, water supply pipe 14, water outlet pipe 12 and water spray pipe 10 are connected.

[0029] A rotating device, one end of which is rotatably connected to the water supply pipe 14, and the other end of which is fixedly connected to the water outlet pipe 12;

[0030] The visual positioning device 9 includes a high-definition visible light camera and an infrared thermal imaging camera, which are connected to the end of the water spray pipe 10 away from the water outlet pipe 12.

[0031] Control system 5 is electrically connected to the rotating device, the high-definition visible light camera, and the infrared thermal imaging camera.

[0032] Under normal lighting conditions, a high-definition visible light camera can quickly locate a flame by analyzing and identifying its characteristics, such as color, shape, and flicker frequency. In environments with limited visible light, such as dense smoke or darkness, an infrared thermal imaging camera can detect the fire source by detecting the thermal radiation of objects. The combination of the high-definition visible light camera and the infrared thermal imaging camera ensures accurate capture of the fire source in various situations. After the high-definition visible light camera or the infrared thermal imaging camera identifies the fire source, it processes the acquired image in real time, uses a deep learning model to quickly compare and analyze the flame features, determines the location of the fire source, and transmits the coordinate information of the fire source in the image and the size of the fire to the control system 5. The control system 5 controls the rotating device to rotate, thereby driving the water outlet pipe 12 and the water spray pipe 10 to rotate, thereby adjusting the position of the water spray pipe 10 so that the nozzle of the water spray pipe 10 is aligned with the fire source. The regulating valve is then opened to allow the water jet to spray out, achieving rapid fire extinguishing.

[0033] In some embodiments, the rotating device includes a rotary motor 4, a mounting cylinder 13, a rotary motor cylinder 11, a first worm, and a first worm wheel. The water supply pipe 14 and the water outlet pipe 12 are rotatably connected and close to each other, with one end extending into the mounting cylinder 13. One end of the mounting cylinder 13 is rotatably connected to the water supply pipe 14, and the other end is fixedly connected to the water outlet pipe 12. The first worm wheel is disposed inside the mounting cylinder 13 and fixedly connected to the water supply pipe 14. The rotary motor cylinder 11 and the mounting cylinder 13 are perpendicular to each other and fixedly connected. The rotary motor 4 is connected to the rotary motor cylinder 11, and the output shaft of the rotary motor 4 extends into the rotary motor cylinder 11. The first worm is connected to the output shaft of the rotary motor 4. The mounting cylinder 13 has a mating hole, through which the teeth of the first worm extend into the mounting cylinder 13 and mesh with the first worm wheel. The rotary motor 4 is electrically connected to the control system 5.

[0034] During the adjustment of the position of the water spray pipe 10, the control system 5 controls the rotary motor 4 to start according to the received coordinate information. The rotary motor 4 drives the first worm to rotate. The first worm cooperates with the first worm wheel. The fixed connection between the first worm wheel and the water supply pipe 14 restricts the first worm wheel from rotating with the first worm. At this time, the first worm rotates around the first worm wheel, driving the rotary motor 4, the rotary motor cylinder 11 and the mounting cylinder 13 to rotate around the second worm wheel, thereby driving the water outlet pipe 12 and the water spray pipe 10 to rotate around the first worm wheel, thus realizing the adjustment of the position of the water spray pipe 10.

[0035] In some embodiments, a first rotary bearing is connected between the water supply pipe 14 and the mounting cylinder 13.

[0036] In some embodiments, an angle adjustment device is also included, comprising an adjustment motor 17, an adjustment cylinder 7, an adjustment motor cylinder 6, a second worm, and a second worm wheel. One end of the water spray pipe 10 and the water outlet pipe 12, which are rotatably connected and close to each other, extends into the adjustment cylinder 7. One end of the adjustment cylinder 7 is rotatably connected to the water outlet pipe 12, and the other end of the adjustment cylinder 7 is fixedly connected to the water spray pipe 10. The second worm wheel is disposed in the adjustment cylinder 7 and is fixedly connected to the water outlet pipe 12. The adjustment motor cylinder 6 is perpendicular to the adjustment cylinder 7 and is fixedly connected. The adjustment motor 17 is connected to the adjustment motor cylinder 6, and the output shaft of the adjustment motor 17 extends into the adjustment motor cylinder 6. The second worm is connected to the output shaft of the adjustment motor 17. The adjustment cylinder 7 is provided with a mating hole, and the gear teeth of the second worm extend into the adjustment cylinder 7 through the mating hole and mesh with the second worm wheel. The adjustment motor 17 is electrically connected to the control system 5.

[0037] After receiving the coordinate information, the control system 5 starts the regulating motor 17. The regulating motor 17 drives the second worm to rotate. The fixed connection between the second worm wheel and the water outlet pipe 12 restricts the rotation of the second worm wheel with the second worm. At this time, the second worm rotates around the second worm wheel, driving the regulating motor 17, the regulating cylinder 7 and the regulating motor cylinder 6 to rotate around the second worm wheel, thereby driving the rotation of the water spray pipe 10 and realizing the angle adjustment of the water spray pipe 10.

[0038] In some embodiments, a second rotary bearing is connected between the water outlet pipe 12 and the regulating cylinder 7.

[0039] In some embodiments, a control motor 8 is connected to the water spray pipe 10, a rotating rod 16 is connected to the output shaft of the control motor 8, a connecting rod 18 is connected to the rotating rod 16, and the end of the connecting rod 18 away from the rotating rod 16 is connected to the regulating valve.

[0040] Once a fire source is detected, the rotation of the control motor 8 is controlled by the control system 5. The control motor 8 drives the rotating rod 16 to rotate, and the rotating rod 16 drives the regulating valve to rotate through the connecting rod 18, thereby opening the regulating valve.

[0041] In some embodiments, the system further includes a pressure control system 5, which includes a pressure sensor 15 disposed in the spray pipe 10 or the outlet pipe 12. The regulating valve is an electric regulating valve, and both the pressure sensor 15 and the electric regulating valve are electrically connected to the control system 5.

[0042] The pressure sensor 15 monitors the water pressure in the pipeline in real time and feeds the water pressure information back to the control system 5. The control system 5 sends an electrical signal to the electric regulating valve according to the coordinate information of the fire source, controls the opening of the electric regulating valve, and realizes the automatic adjustment of the water pressure in the pipeline.

[0043] When the fire source is far away, the control system 5 increases the opening of the electric regulating valve to increase the water supply pressure, so that the water spray pipe 10 can spray a farther and more powerful water jet to extinguish the fire; when the fire source is close, the control system 5 decreases the opening of the electric regulating valve to reduce the water supply pressure, so as to avoid wasting water resources and causing unnecessary damage to the surrounding environment.

[0044] In some embodiments, a displacement device is also included, which includes two slide rails 1, a displacement motor 20 and a drive gear 19. The two slide rails 1 are spaced apart. A slider is provided at the end of the mounting base 2 away from the water inlet base 3. The mounting base 2 is slidably connected to the two slide rails 1 through the slider. A rack is provided on the side wall of one slide rail 1. The displacement motor 20 is fixedly connected to the mounting base 2. The drive gear 19 is provided on the output shaft of the displacement motor 20. The drive gear 19 meshes with the rack. The displacement motor 20 is electrically connected to the control system 5.

[0045] After receiving the location information of the fire source, the control system 5 drives the displacement motor 20 to rotate. The displacement motor 20 drives the drive gear 19 to rotate. Through the cooperation between the drive gear 19 and the rack, the drive gear 19 moves along the rack, thereby driving the mounting base plate 2 to slide on the slide rail 1, realizing the horizontal position adjustment of the fire monitor.

[0046] In some embodiments, a first angle sensor is installed on the water outlet pipe 12, and the first angle sensor is electrically connected to the control system 5.

[0047] During the adjustment of the position of the water spray pipe 10, the first angle sensor measures the horizontal rotation angle of the water pipe 12 and feeds the information back to the control system 5. The control system 5 then determines the start and stop of the rotating motor 4 based on the measurement results, ensuring accurate adjustment of the position of the water spray pipe 10 and ensuring that the water jet sprayed from the water spray pipe 10 is aimed directly at the fire source, thereby achieving rapid fire extinguishing.

[0048] In some embodiments, a second angle sensor is installed on the water spray pipe 10, and the second angle sensor is electrically connected to the control system 5.

[0049] During the adjustment of the position of the water spray pipe 10, the vertical rotation angle of the water spray pipe 10 is measured by the second angle sensor and the information is fed back to the control system 5. The control system 5 then determines the start and stop of the adjustment motor 17 based on the measurement results, ensuring accurate adjustment of the position of the water spray pipe 10 and ensuring that the water jet sprayed from the water spray pipe 10 is directly aimed at the fire source, thereby achieving rapid fire extinguishing.

[0050] During installation, the fire monitor is installed in a suitable location within the protected area, ensuring that there are no obstructions within the field of view of the high-definition visible light camera and the infrared thermal imaging camera. The external water supply pipe and mounting base 2 are connected to achieve water supply.

[0051] During operation, pressure sensor 15 continuously monitors the water pressure in the pipeline and transmits real-time water pressure signals to control system 5. Control system 5 simultaneously receives data from the visual positioning system, such as the distance to the fire source and the size of the fire, and combines this data with the water pressure signal from pressure sensor 15 to perform calculations based on a preset algorithm. If the fire source is far away and the fire is large, the calculation requires an increase in water supply pressure, and control system 5 sends a command to the electric regulating valve to increase its opening. If the fire source is close and the fire is small, the calculation requires a decrease in water supply pressure, and control system 5 sends a command to the electric regulating valve to decrease its opening. Upon receiving the command, the electric regulating valve quickly adjusts its opening to regulate the water pressure. Pressure sensor 15 feeds back the new water pressure signal to control system 5, which then determines whether the water pressure has reached the expected value. If not, it will issue another adjustment command until the water pressure meets the fire extinguishing requirements.
