Description

Technical Field

[0001] The invention relates to the technical field of intelligent robots, and in particular to an intelligent inspection robot with an alarm function. Background Art

[0002] The intelligent inspection robot is an advanced intelligent device that uses a mobile robot as a carrier, is equipped with a variety of detection instruments and sensors, and uses multi-field information fusion technology to achieve autonomous movement, autonomous inspection and data analysis.

[0003] With the continuous development of society, more and more warehouses and factories are using intelligent inspection robots. Inspection robots can be used for 24-hour uninterrupted patrol and inspection, greatly reducing labor costs. The inspection robots in the existing technology can be equipped with fire extinguishing functions according to the use environment, but can only extinguish a single type of fire. Different types of goods are often stacked in warehouses and factories. Affected by the material of the goods, some goods are suitable for extinguishing with water-based fire extinguishing agents, while cables in warehouses and factories cannot be extinguished with water-based fire extinguishing agents, and can only be extinguished with dry powder fire extinguishing agents. In addition, the inspection robot cannot quickly distinguish between goods and cables. Once the wrong fire extinguishing agent is used, the fire will further expand. In addition, there is a common problem with existing patrol robots. If the robot itself is large, it cannot patrol a small area. If the robot itself is designed to be small, it is not conducive to the stability of the robot when walking. Therefore, the existing intelligent inspection robots are not compatible with each other in terms of stability during action and small area space inspection.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using existing inspection robots, and even if they can be solved, they need to be solved through external tools, which makes it impossible to achieve the desired effect.

[0045] The fire extinguishing mechanism 121 also includes a cross 12108, the cross 12108 is installed on the mechanical arm 12, the mounting frame 12101 is stuck in the cross 12108 and slides therein, a nozzle 12109 is fixedly connected in the mounting frame 12101, a hose is commonly connected between the storage tank 12107 and the nozzle 12109, and an extension rod 12110 is symmetrically fixed on the mounting frame 12101. When the extension rod 12110 is affected by high temperature, the telescopic end of the extension rod 12110 can be extended, and a sealing member symmetrically slidably connected in the mounting frame 12101 Plate 12111, the blocking plate 12111 is used to block the nozzle of the nozzle 12109, the telescopic end of the extension rod 12110 is fixedly connected to the blocking plate 12111 through the vertical plate, a gravity block 12112 is hinged at the bottom of the cross 12108, and a connecting assembly is connected to the cross 12108.

[0046] As a further definition of the base extension unit 2 of the present invention, the drive unit 21 includes four drive shells 2101, each drive shell 2101 is located below the robot body 11, the inner bottom wall of each drive shell 2101 is fixedly connected with four rotating seats 2102, the inner wall of each group of rotating seats 2102 is rotatably connected with a limiting shaft 2103, the outer surface of each limiting shaft 2103 is fixedly connected with a first gear 2104, the inner wall of each drive shell 2101 is fixedly connected with a forward and reverse motor 2105, and the inner wall of each drive shell 2101 is fixedly connected with The output end of the power of each forward and reverse motor 2105 is fixedly connected to two second gears 2107 and is rotatably connected to the inner wall of the limiting tube 2106. The outer surface of each second gear 2107 and the first gear 2104 is meshed and connected with a synchronous belt 2108. The outer surface of each limiting shaft 2103 is fixedly connected with a moving wheel 2109. By providing a driving unit 21, the driving unit 21 is used to drive the robot to move forward and backward as a whole. Therefore, a convenient moving method can be provided, and the robot has high mobility in daily patrols.

[0047] A limiting plate 2110 is disposed on the outer side of each moving wheel 2109, and a side of each limiting plate 2110 close to the moving wheel 2109 is in contact with the outer surface of the moving wheel 2109. The limiting plate 2110 is inserted into the moving wheel 2109 to further generate synchronization with the moving wheel 2109;

[0048] A first bolt 2111 is disposed on the outer side of each limiting plate 2110. One end of each first bolt 2111 close to the limiting plate 2110 penetrates the limiting plate 2110 and is threadedly connected to the inner wall of the limiting shaft 2103. The first bolt 2111 can further increase the limiting relationship between the moving wheel 2109 and the limiting shaft 2103, thereby ensuring that the moving wheel 2109 can rotate stably.

[0049] The specific implementation method of this embodiment is as follows: first, the image integration box 13 is used to automatically identify and guide the route to complete automatic obstacle avoidance. The robot arm 12 is equipped with an integrated danger detection device for measuring temperature and air quality. When a dangerous situation is found, an alarm signal can be sent to the office through the signal transmission integrator 14. Then, the forward and reverse motors 2105 are electrically connected through wires. First, the forward and reverse motors 2105 are fixed on the inner wall of the drive shell 2101 to ensure the stability of the forward and reverse motors 2105 during operation. Then, the output rod of the forward and reverse motors 2105 is rotatably connected to the limit tube 2106, and the limit tube 2106 is fixedly connected to the drive shell 2101, thereby further ensuring the stability of the forward and reverse motors 2105. At this time, the power provided by the forward and reverse motors 2105 can drive the two second gears 2107 to rotate. At this time, the second gear 2107 is rotatably connected to the first gear 2104 through the synchronous belt 2108. Therefore, when the forward and reverse motor 2105 provides power to drive the two second gears 2107 to rotate, the two second gears 2107 can respectively drive the two synchronous belts 2108 to achieve the effect of driving the first gear 2104 to rotate. The first gear 2104 is fixedly connected to the limiting shaft 2103. Therefore, when the first gear 2104 rotates, the limiting shaft 2103 can be driven to rotate. At this time, the rotational connection relationship between the rotating seat 2102 and the limiting shaft 2103 is utilized to ensure that each limiting shaft 2103 can rotate stably inside the two rotating seats 2102. At this time, the outer surface of each limiting shaft 2103 is provided with a protrusion that fits the groove on the inner wall of the moving wheel 2109, so as to achieve the purpose of using the limiting shaft 2103 to drive the moving wheel 2109 to rotate. Finally, the limiting plate 2110 and the first bolt 2111 are used to reinforce the connection relationship between the moving wheel 2109 and the limiting shaft 2103.

[0050] Initially, the telescopic end of the extension rod 12110 is in a retracted state, the first solenoid valve 12105 and the second solenoid valve 12106 are both in a closed state, and most of the nozzles of the nozzle 12109 are blocked by the two blocking plates 12111. When a fire occurs inside the warehouse, there are two situations. The first situation is that the goods in the warehouse are on fire. At this time, the image integration box 13 detects the fire and controls the robot to move to the fire site, and then controls the robot arm 12 to drive the mounting frame 12101 to move near the fire site. At this time, the cutting knife 100, the magnet 12103 and the two extension rods 12110 are close to the fire site. There is no current inside the goods, and the magnet 12103 will not be affected. The temperature of the fire is transmitted to the inner cavity of the two extension rods 12110. The air in the inner cavity of the two extension rods 12110 expands due to the high temperature, and then the two extension rods 12110 extend. It is worth noting that the extension length of the two extension rods 12110 is affected by the range of the fire. When the fire is spreading, the telescopic ends of the two extension rods 12110 extend longer, and when the fire is spreading, the telescopic ends of the two extension rods 12110 extend shorter. When the telescopic ends of the extension rods 12110 extend, the vertical plates drive the adjacent blocking plates 12111 to slide along the mounting frame 12101. After the blocking plates 12111 slide, part of the nozzle of the nozzle 12109 is no longer blocked, and then the first solenoid valve 12105 is controlled to open. The high-pressure air in the gas tank 12104 enters the storage tank 12107 on the right through the first solenoid valve 12105, so that the water-based fire extinguishing agent in the storage tank 12107 on the right enters the nozzle 12109 through the hose, and is sprayed at the fire site through the nozzle 12109, thereby achieving rapid fire extinguishing. By partially blocking the nozzle of the nozzle 12109 through two sealing plates 12111, the water-based fire extinguishing agent can be sprayed at the fire site more accurately, thereby improving the fire extinguishing efficiency.

[0051] The second situation is that the cables inside the warehouse catch fire. When the fire alarm system and automatic power-off device in the warehouse fail, the fire will continue to spread. At this time, the image integration box 13 detects the fire and controls the robot to move to the fire site, and then controls the robot arm 12 to drive the mounting frame 12101 to move near the fire site. At this time, the cutting knife 100, the magnet 12103 and the two extension rods 12110 are close to the fire site. At the same time, the temperature of the fire is transmitted to the inner cavity of the two extension rods 12110, and the above steps are repeated to make the two blocking plates 12111 slide. Since the cable is energized, the cable will generate a magnetic field. The magnet 12103 is affected by the magnetic field, which will change the magnetic field of the magnet 12103. After the magnetic field of the magnet 12103 changes, the second electromagnetic Valve 12106, and at the same time, the magnet 12103 transmits a signal to the warehouse's power-off system, causing the power-off system to close the circuit, and the cable is no longer energized. The high-pressure air in the gas tank 12104 enters the storage tank 12107 on the left through the second solenoid valve 12106, so that the dry powder fire extinguishing agent in the storage tank 12107 on the left enters the nozzle 12109 through the hose, and is sprayed at the fire site through the nozzle 12109, thereby achieving rapid fire extinguishing. Subsequently, the cutting knife 100 cuts off the fire site of the cable to prevent re-ignition. The magnetic field of the magnet 12103 changes, and the burning item can be judged, thereby preventing the cable from catching fire. The nozzle 12109 sprays a water-based fire extinguishing agent, and the current of the cable is conducted to the robot through the water-based fire extinguishing agent, causing damage to the robot.

[0052] When the cable is placed in an inclined state or in a bent state, the image integration box 13 controls the mechanical arm 12 to drive the cross 12108 and the mounting frame 12101 to rotate, and the mounting frame 12101 drives the nozzle 12109 to rotate, so that the placement angle of the nozzle 12109 and the cable are consistent. At this time, the gravity block 12112 is affected by its own gravity and rotates with the connection point of the cross 12108 as the center of the circle. When the cross 12108 rotates clockwise, the gravity block 12112 rotates counterclockwise relative to the cross 12108, and pulls the mounting frame 12101 through the pull rope in the connecting component. The mounting frame 12101 is forced to slide to the left along the cross 12108 and drive the nozzle 12109 to move, thereby enabling the nozzle 12109 to be tilted upward relative to the fire. When the nozzle 12109 sprays dry powder fire extinguishing agent, due to the characteristics of dry powder fire extinguishing agent, the initial speed of the dry powder fire extinguishing agent when sprayed is extremely fast, and then it decays rapidly. Through the above steps, the dry powder fire extinguishing agent can fall on the cable after being sprayed, thereby further improving the fire extinguishing effect. When the fire is extinguished, the mechanical arm 12 drives the cross 12108 and the mounting frame 12101 to rotate and reset, and then the gravity block 12112 rotates and resets. The gravity block 12112 drives the mounting frame 12101 to slide and reset through the pull rope in the connecting assembly, and the mounting frame 12101 drives the nozzle 12109 to move and reset. When the cross 12108 rotates counterclockwise, the gravity block 12112 rotates clockwise relative to the cross 12108, and the above steps are repeated in the opposite direction to achieve the same effect.
