Description

Technical Field

[0001] This invention relates to the field of fire protection technology, specifically to an automatic tracking fire extinguishing device. Background Technology

[0002] With the development of society and the economy, the demand for fire protection in small spaces such as homes, shops, computer rooms, power distribution cabinets, energy storage compartments, and electric vehicle sheds is increasing day by day.

[0003] Existing small-space fire extinguishing and fire detection technologies mainly include the following categories, all of which have significant shortcomings: (1) Passive-triggered fire extinguishing balls / fire extinguishing patches: They rely on flame contact or high ambient temperature to break and release fire extinguishing agent. They are one-time passive fire extinguishing, without active detection or fire source location. Fire extinguishing is blind and cannot be re-prevented. (2) Standalone smoke / heat detectors: They can only sound an alarm and do not have any fire extinguishing capabilities, relying on manual or external fire fighting; (3) Split-type monitoring and fire extinguishing equipment: The monitoring camera and the fire extinguishing device are deployed independently and do not work together, so they cannot automatically aim and spray after the fire is confirmed.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example 1 like Figure 1-8 As shown, this embodiment includes a water tank 100, a water pump 150 installed inside the water tank 100, and a pan-tilt mechanism 200 connected to the water tank 100. Specifically, a water inlet is provided on one side of the water tank 100, and a sealing cover is provided at the water inlet, with the sealing cover threadedly connected to the water inlet. This facilitates the replenishment of fire extinguishing medium into the water tank 100, while the sealing cover effectively prevents the fire extinguishing medium in the water tank 100 from leaking when not in operation.

[0021] In this embodiment, the water tank 100 is fixed to the mounting surface such as a wall or ceiling by expansion bolts, thereby ensuring the stability of the device during fire extinguishing operations and preventing the water tank 100 from shifting due to the reaction force of the water flow.

[0022] The gimbal mechanism 200 includes a support base 201 that is fixedly connected to the water tank 100; in this embodiment, the support base 201 is a hollow cylindrical structure; and the support base 201 is fixedly installed at the bottom center of the water tank 100.

[0023] The rotating housing 202 is mounted on the support base 201 via a bearing; in this embodiment, the rotating housing 202 is a cylindrical housing with the opening facing downwards; thus, the rotating housing 202 can rotate 360° horizontally on the support base 201 via the bearing.

[0024] In this embodiment, the outer surface of the rotating housing 202 is also fitted with a shell 50. The rotating housing 202 is rotatably connected to the shell 50 through a bearing, and the upper end of the shell 50 is fixedly connected to the bottom of the water tank 100, thereby protecting the internal components of the rotating housing 202 and preventing dust, water vapor and other impurities from entering and affecting the transmission accuracy and service life.

[0025] In this embodiment, there is a limiting cavity between the rotating housing 202 and the outer shell 50; a first limiting block is fixedly connected to the outer surface of the rotating housing 202; a second limiting block is provided on the inner wall of the outer shell 50; thereby, the rotation angle of the rotating housing 202 is limited by the cooperation of the first limiting block and the second limiting block, so as to avoid the internal circuits from getting tangled or damaged due to excessive rotation.

[0026] A drive assembly is disposed within the rotating housing 202 and drives the rotating housing 202 to rotate around the axis of the support base 201. The drive assembly includes a rotary motor 210 fixedly disposed within the rotating housing 202. The output end of the rotary motor 210 is connected to a drive gear 211. A driven gear 212 that meshes with the drive gear 211 is fixedly sleeved on the outer surface of the support base 201. Thus, when the rotary motor 210 drives the drive gear 211 to rotate, the meshing transmission between the drive gear 211 and the driven gear 212 drives the rotating housing 202 to rotate horizontally around the axis of the support base 201, thereby achieving precise positioning of the pan-tilt mechanism 200 in the horizontal direction, and thereby driving the nozzle 205 (described in detail below) to aim at the fire source for fire extinguishing operations.

[0027] In this embodiment, the rotary motor 210 is fixedly mounted on the inner wall of the rotary housing 202 by a motor mount, and the motor mount is fixedly connected to the rotary housing 202 by bolts, thereby ensuring the stability of the rotary motor 210 during operation. A housing 203 is fixedly connected to the rotating housing 202; in this embodiment, the housing 203 is fixedly disposed at the bottom of the rotating housing 202; and the housing 203 has a hollow ∩-shaped structure.

[0028] The gimbal ball head 205, which is mounted inside the housing 203, is rotated via the pivot 204. In this embodiment, the gimbal ball head 205 has a spherical structure, and the center of the ball head 205 is located on the axis of the pivot 204. Thus, the gimbal ball head 205 can pitch and rotate within the housing 203 around the axis of the pivot 204, thereby adjusting the spray angle of the nozzle 206 and enabling the nozzle 206 to accurately extinguish fires at different heights of the fire source.

[0029] In this embodiment, there are two rotating shafts 204, which are fixedly mounted on opposite side walls of the housing 203 and are coaxially arranged. The gimbal ball head 205 is rotatably connected to the housing 203 through the two rotating shafts 204. Thus, the gimbal ball head 205 can pitch and rotate within the housing 203 around the common axis of the two rotating shafts 204.

[0030] A pitch drive assembly 220 drives the gimbal ball head 205 to swing along the axial direction of the water tank 100. In this embodiment, the pitch drive assembly 220 includes a pitch motor 221 fixedly installed in the housing 203, and the output end of the pitch motor 221 is fixedly connected to the rotating shaft 204. Specifically, the pitch motor 221 is coaxially fixedly connected to one of the two rotating shafts 204, and the other rotating shaft 204 is rotatably connected to the housing 203 through a bearing. Thus, when the pitch motor 221 drives the rotating shaft 204 fixedly connected to it to rotate, it drives the gimbal ball head 205 to swing in pitch around the axis of the rotating shaft 204, thereby realizing the angle adjustment of the nozzle 206 in the vertical direction, so that the nozzle 206 can be aimed at different height positions of the fire source for precise fire extinguishing operations.

[0031] The gimbal head 205 is equipped with a nozzle 206, a camera module 207, and an infrared probe 208. In this embodiment, the camera module 207 is used to collect image information of the fire source area in real time, and the infrared probe 208 is used to detect the thermal radiation signal of the fire source. Thus, the camera module 207 and the infrared probe 208 can work together to achieve accurate identification and positioning of the fire source, and transmit the collected image information and thermal radiation signal to the control unit in real time (described in detail below).

[0032] In this embodiment, the nozzle 206 is fixedly installed at the front end of the gimbal ball head 205, and the nozzle 206 is connected to the water pump 150 through the pipeline assembly; thus, the fire extinguishing medium can be pressurized by the water pump 150 and transported to the nozzle 206 through the pipeline assembly, and sprayed by the nozzle 206 to the fire source, thereby achieving precise fire extinguishing operation.

[0033] The gimbal head 205 is equipped with a control unit. The drive assembly, pitch drive assembly 220, camera module 207, infrared probe 208, and water pump 150 are all electrically connected to the control unit. The control unit controls the operation of the drive assembly and pitch drive assembly 220 based on the fire source position signal detected by the infrared probe 208 and camera module 207, so that the nozzle 206 is aimed at the fire source, and controls the water pump 150 to start, so that the fire extinguishing medium is sprayed through the nozzle 206 to extinguish the fire.

[0034] The control unit includes a control circuit board 410, a flame vision recognition board 420 electrically connected to the control circuit board 410, and a lamp board 430; the drive assembly, the pitch drive assembly 220, the camera module 206, the infrared probe 207, the ultraviolet phototube 209, and the water pump 150 are all electrically connected to the control circuit board 410; in this embodiment, the flame vision recognition board 420 is electrically connected to the camera module 206 and is used to receive image information collected by the camera module 206, and to perform flame feature extraction and recognition processing on the image information to determine whether there is a fire source and the specific location of the fire source; the flame vision recognition board 420 transmits the recognition result to the control circuit board 410, and the control circuit board 410 generates corresponding control commands according to the recognition result, which drive the horizontal rotation drive assembly 210 and the pitch drive assembly 220 to move, so that the gimbal ball head 204 drives the nozzle 205, the camera module 206 and the infrared probe 207 to rotate synchronously until the spray direction of the nozzle 205 is precisely aligned with the fire source position.

[0035] The lamp board 430 is electrically connected to the control circuit board 410, which controls the turning on and off of the light on the lamp board 430. In this embodiment, the illumination lamp on the lamp board 430 is disposed on the outer surface of the gimbal ball head 204 to provide illumination and status indication functions.

[0036] The bottom of the housing 203 is equipped with an ultraviolet phototube 209, which is electrically connected to the control unit. In this embodiment, the ultraviolet phototube 209 is used to detect the ultraviolet radiation signal of the flame in the environment where the fire extinguishing equipment is located. When the ultraviolet light signal generated by the flame is detected, the signal is transmitted to the control unit. The control unit determines whether to trigger the fire extinguishing action according to a preset threshold, thereby realizing a rapid response to the initial fire. At the same time, the detection signal of the ultraviolet phototube 209 and the detection signal of the infrared probe 207 are mutually verified to reduce the probability of false triggering caused by misjudgment by a single sensor and improve the accuracy and reliability of the fire extinguishing equipment in judging the fire situation.

[0037] The gimbal head 205 is also equipped with an attitude sensor, which is electrically connected to the control unit. Thus, the attitude sensor can detect the angle changes of the gimbal head 205 in the horizontal and pitch directions in real time and feed the attitude data back to the control unit. The control unit performs closed-loop control of the rotation of the gimbal assembly based on the attitude data, ensuring that the spray direction of the nozzle 205 can remain stably aimed at the fire source even when the equipment itself is displaced or vibrates, thereby improving the dynamic response capability and anti-interference performance of the fire extinguishing process.

[0038] The gimbal head 205 is also equipped with a speaker, which is electrically connected to the control unit; the speaker can emit a voice alarm signal to promptly remind on-site personnel to evacuate when a fire is detected.

[0039] The piping assembly includes a first rotary joint 310 that passes through the hollow cavity of the support base 201. The first end of the first rotary joint 310 extends into the water tank 100 and is connected to the outlet of the water pump 150. The second end of the rotary joint 310 extends out of the support base 201 and is connected to a horizontal pipe 320 via an elbow. The end of the horizontal pipe 320 away from the rotary joint 310 is connected to a vertical pipe 330 via an elbow. The end of the vertical pipe 330 away from the horizontal pipe 320 is connected to a second rotary joint 340 that extends into the pan-tilt head 205 via an elbow. The end of the second rotary joint 340 away from the vertical pipe 330 is connected to the nozzle 206 via an elbow. Thus, through the cooperation of the first rotary joint 310 and the second rotary joint 340, the piping assembly can flexibly follow the horizontal and vertical rotation of the pan-tilt head 205, preventing the piping from twisting or getting stuck due to the rotation of the pan-tilt head 205, and ensuring the continuity and smooth flow of the extinguishing medium during the spraying process.

[0040] In this embodiment, the nozzle 206 is connected to the elbow pipe of the second rotary joint 340 via an elbow pipe; the nozzle 206 is perpendicular to the second rotary joint 340.

[0041] In this embodiment, the second rotary joint 340 is rotatably connected to the gimbal ball head 205 via a bearing; that is, the gimbal ball head 204 is rotatably mounted on the housing 203 via the rotating shaft 204 and the second rotary joint 340, and the axis of the second rotary joint 340 is coaxial with the axis of the rotating shaft 204.

[0042] The water tank 100 is detachably connected to the gimbal mechanism 200 via a connecting assembly 160. The connecting assembly 160 includes a connecting post 161 and a connector 162 fixed to the outer surface of the bottom of the water tank 100. At least two L-shaped buckles 163 are evenly provided at the lower end of the outer surface of the connecting post 161. The connector 162 is annular and has a sliding groove 164 that corresponds to and cooperates with the L-shaped buckles 163. The first end of the sliding groove 164 has an opening 165 for the L-shaped buckles 163 to be inserted into the sliding groove 164, and the second end of the sliding groove 164 has a limiting block. Thus, the gimbal mechanism 200 can be detachably connected to the water tank 100 via the connecting assembly 160, thereby allowing the water tank 100 and the gimbal mechanism 200 to be installed separately.

[0043] That is, the L-shaped buckle 163 at the lower end of the connecting post 161 is inserted into the opening 165 at the first end of the slide groove 164, slides along the slide groove 164 to the second end, and the movement is limited by the limiting block, thereby realizing the fixed connection between the connecting post 161 and the connector 162; when disassembling, the L-shaped buckle 163 can be separated by sliding it in the opposite direction to the opening 165.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the technical solutions of the present invention have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
