Description

Technical Field

[0001] This utility model relates to the field of fire-fighting robot technology, and in particular to an automatic fire extinguisher triggering device and system for a robot dog. Background Technology

[0002] With the rapid development of intelligent robot technology, quadruped robots (commonly known as "robot dogs") have been widely adopted in fields such as inspection, rescue, and security due to their excellent terrain adaptability, flexibility, and load-bearing capacity. These robot dogs are typically equipped with multiple sensors (such as cameras and thermal imagers), enabling them to effectively identify abnormal situations such as fires and intrusions by strangers, and send alarm information to monitoring centers or mobile apps via the network. In fire emergency scenarios, robot dogs can replace humans in high-risk environments such as high temperatures, toxic substances, and collapses to perform initial fire suppression tasks, demonstrating significant social value.

[0003] However, existing inspection robot dogs are mostly limited to "identification" and "alarm" functions, lacking "response" capabilities. When they detect an initial fire, they cannot take any proactive intervention and can only wait for human intervention, often missing the best opportunity to extinguish the fire and causing it to spread. Therefore, how to endow existing mobile robot platforms with proactive firefighting capabilities has become a practical problem that urgently needs to be solved.

[0004] Integrating a fire extinguisher into a robot dog presents several technical challenges: first, it requires a small, lightweight, and efficient fire extinguisher; second, it needs a reliable automated triggering mechanism that can accurately activate the fire extinguisher upon receiving a command; and third, it needs to be easy to replace to support continuous operation. This invention aims to solve these problems.

[0005] Therefore, this utility model provides an automatic fire extinguisher triggering device and system for robot dogs to solve the above problems. Utility Model Content

[0006] This invention addresses the shortcomings of existing technologies by developing an automatic fire extinguisher triggering device and system for robot dogs. The main objective is to provide an automatic fire extinguisher triggering device for robot dogs that is compact in structure, reliable in triggering, and quick to replace.

[0007] On the one hand, the technical solution of this utility model to solve the technical problem is an automatic fire extinguisher triggering device for a robot dog, comprising: The robot dog body has a drive mechanism and a fire extinguisher fixing mechanism on both sides, and a central control compartment inside. The drive mechanism includes two push rod motors and one push rod. One push rod motor is connected to the push rod to control the switch of the fire extinguisher, and the other push rod motor directly controls the switch of the fire extinguisher. The fire extinguisher fixing mechanism includes fire extinguisher clamps symmetrically arranged on both sides of the robot dog, with two fire extinguisher clamps on each side; The central control unit contains an industrial computer, relays, serial relays, and motor mounting brackets for controlling the motors.

[0008] The present invention is further configured such that: the push rod motor includes push rod motor 1 and push rod motor 2, push rod motor 1 is located above push rod motor 2, and push rod motor 2 is mounted on a motor mounting base; Fire extinguishers include a right-side fire extinguisher and a left-side fire extinguisher; The push rod passes through the central control compartment and connects to the push rod motor 1. The push rod motor 1 controls the switch of the fire extinguisher on the right side through the push rod, and the push rod motor 2 passes through the central control compartment and directly controls the switch of the fire extinguisher on the left side.

[0009] The present invention is further configured such that: the fire extinguisher is a straight-cylinder aerosol fire extinguisher with a fire extinguishing rating of 8B and a spray duration of 15 seconds or more during fire extinguishing.

[0010] The present invention is further configured such that: the fire extinguisher clamp includes a right fire extinguisher clamp 1, a right fire extinguisher clamp 2, a left fire extinguisher clamp 1, and a left fire extinguisher clamp 2; The fire extinguisher is detachably mounted on two fire extinguisher clamps on both sides.

[0011] The present invention is further configured such that: the signal output terminal of the industrial control computer is connected to the serial port relay, the serial port relay is connected to the control terminal of the relay to control the switch of the relay, and the power output terminal of the relay is connected to the power input terminal of the push rod motor; The relay includes relay 1 and relay 2, which are respectively connected to push rod motor 1 and push rod motor 2.

[0012] On the other hand, this utility model also provides an automatic fire extinguisher triggering system for a robot dog, which is applied to an automatic fire extinguisher triggering device for a robot dog to control the robot dog to perform automatic fire extinguishing, including: an industrial control computer and a robot dog body interface. The industrial control computer includes a USB interface, a LAN interface, and a power interface, while the robot dog's main body interfaces include a 12V power output, a 5V power output, and a LAN interface. The power interface receives the 12V power output from the robot dog via a 12V splitter; The USB interface connects to the gas detector and serial relay via a USB to 485 converter. The USB interface also connects directly to the USB wireless network card, and the USB interface also connects directly to the microphone and speaker. The LAN interface connects to the dual-optical pod, and the LAN interface also connects to a switch.

[0013] The present invention is further configured such that: a serial port relay connects relay 1 and relay 2, relay 1 is connected to push rod motor 1, and relay 2 is connected to push rod motor 2.

[0015] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects: This invention proposes an automatic fire extinguisher triggering device and system for a robotic dog. By installing the automatic fire extinguishing triggering device and system on the robotic dog itself, the robotic dog is upgraded from a "patrol and alarm" unit to an integrated "patrol-fire extinguishing" platform, capable of immediate handling of initial fires and effectively suppressing the spread of fire. It utilizes a miniature aerosol fire extinguisher and a miniature push rod motor, resulting in a small size and light weight without affecting the robotic dog's mobility and maneuverability. The electric push rod serves as the actuator, providing strong thrust and precise action, ensuring reliable triggering of the fire extinguisher every time. The industrial control computer can be seamlessly integrated with the robotic dog's existing visual recognition system, achieving fully automatic fire identification and response, supporting multiple spray modes, and offering flexible strategies. The fire extinguisher is detachable and can be quickly replaced after use, ensuring the device's continuous operational capability.

[0016] In summary, this utility model enables the robot dog to autonomously, accurately, and quickly extinguish initial fires during inspections, solving the problem that existing inspection robot dogs only have alarm recognition functions but cannot actively intervene in fire extinguishing.

[0022] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings. The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below.

[0023] Example 1 like Figure 1 and Figure 2 As shown, an automatic fire extinguisher triggering device for a robot dog includes... The robot dog body has a drive mechanism and a fire extinguisher fixing mechanism on both sides, and a central control compartment inside. The drive mechanism includes two push rod motors and one push rod. One push rod motor is connected to the push rod to control the switch of the fire extinguisher, and the other push rod motor directly controls the switch of the fire extinguisher. The fire extinguisher fixing mechanism includes fire extinguisher clamps (or brackets with locking mechanisms) symmetrically arranged on both sides of the robot dog, with two fire extinguisher clamps on each side; The central control compartment contains an industrial computer, relays, serial port relays, and motor mounting brackets for controlling the motors. The push rod motor is mounted on the motor mounting bracket.

[0024] In a specific embodiment, the push rod motor includes push rod motor 1 and push rod motor 2, with push rod motor 1 located above push rod motor 2 and push rod motor 2 mounted on a motor mounting base; Fire extinguishers include a right-side fire extinguisher and a left-side fire extinguisher; The push rod motor is specifically a miniature DC electric push rod motor with a stroke of 20mm, which can control the extension and retraction of the push rod, and its thrust is not less than 150N; at the same time, a metal push rod pressure head connector can be set at the end of the push rod, and the contact of the pressure head matches the cylindrical surface of the fire extinguisher button to ensure that the fire extinguisher button can be reliably pressed into place. The push rod passes through the central control compartment and connects to push rod motor 1. Push rod motor 1 controls the switch of the fire extinguisher on the right side through the push rod, and push rod motor 2 passes through the central control compartment to directly control the switch of the fire extinguisher on the left side.

[0025] The fire extinguisher is a straight-cylinder aerosol fire extinguisher with a fire extinguishing rating of 8B. The spray duration during extinguishing is greater than or equal to 15 seconds, and it is suitable for extinguishing Class B, Class C, and Class E fires.

[0026] The fire extinguisher clamps include right-side fire extinguisher clamp 1, right-side fire extinguisher clamp 2, left-side fire extinguisher clamp 1, and left-side fire extinguisher clamp 2; The fire extinguisher is detachably mounted on two fire extinguisher clamps on both sides. The inner diameter of the fire extinguisher clamps is compatible with the outer diameter of the straight-tube aerosol fire extinguisher. Specifically, the fire extinguisher clamps are 40mm in diameter, and the straight-tube aerosol fire extinguisher has a length of 265mm and a diameter of 40mm. The fire extinguisher clamps have screw holes at both ends, which are fixed to the machine dog body with two screws, thereby realizing the installation and replacement of the fire extinguisher.

[0027] The signal output terminal of the industrial control computer is connected to the serial port relay, the serial port relay is connected to the control terminal of the relay to control the relay's switch, and the power output terminal of the relay is connected to the power input terminal of the push rod motor. The relay includes relay 1 and relay 2, which are respectively connected to push rod motor 1 and push rod motor 2.

[0028] Example 2 like Figure 3 As shown, an automatic fire extinguisher triggering system for a robot dog is applied to an automatic fire extinguisher triggering device for a robot dog to control the robot dog to perform automatic fire extinguishing, including: an industrial control computer and an interface between the robot dog body; The industrial control computer includes a USB interface, a LAN interface, and a power interface, while the robot dog's main body interfaces include a 12V power output, a 5V power output, and a LAN interface. The power interface receives the 12V power output from the robot dog via a 12V splitter; The USB interface connects to the gas detector and serial relay via a USB to 485 converter. The USB interface also connects directly to the USB wireless network card, and the USB interface also connects directly to the microphone and speaker. The LAN2 interface connects to the dual-optical pod, which operates at a voltage range of 7-72V. The LAN1 interface connects to the switch, which in turn connects to the machine dog's LAN interface. The industrial control computer and the machine dog exchange information via the switch.

[0029] The serial port relay connects relay 1 and relay 2. Relay 1 is connected to push rod motor 1, and relay 2 is connected to push rod motor 2. The serial port relay controls the switching of relay 1 and relay 2, thereby controlling the operation of the push rod motor.

[0030] The 12V power output from the robot dog interface powers the dual-light pod, relay 1, relay 2, serial port relay, and gas detector via a 12V splitter.

[0031] The working principle is as follows: The robot dog captures environmental information through its dual-light pod equipped with a gas detector and image recognition sensor. This information is transmitted to an industrial control computer. The computer determines the fire situation based on the environmental information and sends commands to serial port relays. These relays control the switching of relays 1 and 2, which in turn control the operation of the push rod motors. Specifically, upon receiving a "start" command, the relay module connects the power supply to the corresponding push rod motor, causing it to run in the forward direction. The push rod extends 20mm, pressing the button on the straight-tube aerosol fire extinguisher to trigger the extinguisher to spray for 15 seconds until the spray is complete. After spraying, the industrial control computer can control the relay to reverse the power polarity, causing the push rod motor to run in the reverse direction and retract the push rod, preparing for the replacement of a new fire extinguisher.

[0032] The industrial control computer can independently control the push rod motors on the left and right sides of the robot dog to achieve single-sided fire extinguisher spraying, simultaneous spraying on both sides, or alternating spraying on both sides. It can then intelligently select to activate single-sided or double-sided fire extinguishers according to the size and location of the fire, optimizing fire extinguishing efficiency and saving extinguishing agents.

[0033] The industrial computer connects to a USB wireless network card via a USB interface to achieve wireless network connectivity and upload work records.

[0034] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
