Abstract
Description
Technical Field
[0001] This invention relates to the field of detection robot technology, and in particular to a gas detection robot for industrial safety inspection. Background Technology
[0002] In industrial production scenarios such as petrochemicals, mining, metallurgy, and warehousing and logistics, there is often a risk of the generation or leakage of toxic and harmful gases (such as hydrogen sulfide, carbon monoxide, and ammonia) and flammable and explosive gases (such as methane, hydrogen, and propane). These gases are characterized by their high degree of concealment, rapid diffusion, and high hazard. Once the concentration exceeds the standard or a leak occurs, it will not only cause economic losses such as equipment corrosion and production interruption, but may also lead to major safety accidents such as personnel poisoning, asphyxiation, fire, and explosion, seriously threatening the safety and stability of industrial production. Therefore, real-time, accurate, and comprehensive detection and monitoring of the composition and concentration of gases in the industrial environment is one of the core links in industrial safety inspection work.
[0003] In existing technologies, robots are typically used for inspection to ensure safety and efficiency. However, if high-precision detectors are used during robot inspection, the cost of long-term use is high. On the other hand, using general coarse detectors cannot guarantee the accuracy of the detection. It is difficult to achieve a good balance between detection accuracy and cost. Summary of the Invention
[0004] The purpose of this invention is to solve the problems in the prior art by proposing a gas detection robot for industrial safety inspection.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A gas detection robot for industrial safety inspection includes a chassis and a main control module. The main control module is fixedly connected to the upper surface of the chassis. An outer shell and a bottom cover are fixedly connected to the upper and lower surfaces of the chassis, respectively. A drive mechanism is provided at the chassis. The drive mechanism consists of a walking component and a pumping component. The walking component includes two rotating shafts, which are rotatably connected to two inner sidewalls opposite to the outer shell through bearings. The pumping component includes an air cylinder, which is fixedly connected to the inner top wall of the outer shell. A detection mechanism is provided at the outer casing. The detection mechanism consists of a coarse detection component, a fine detection component, and a control component. The coarse detection component includes a hollow gas storage box, which is fixedly connected to the inner top wall of the outer casing. The fine detection component includes a detection cylinder, which is fixedly connected to the inner top wall of the outer casing. The control component includes a support block, which is threadedly connected to a screw. The screw is rotatably connected to an adjustment plate via a bearing. A time delay switch is fixedly connected to the lower surface of the adjustment plate.
[0006] Furthermore, the walking assembly also includes two servo motors. The servo motors are fixedly connected to two inner sidewalls opposite to the chassis. Each inner sidewall opposite to the chassis is rotatably connected to a drive shaft and a wheel via bearings. The drive shaft is fixedly connected to the output shaft of the corresponding servo motor. A drive wheel is fixedly connected to the end of the drive shaft away from the servo motor. The drive wheel and the wheel on the same side cooperate with a track. One drive shaft is fixedly connected to a second pulley, and one wheel is fixedly connected to a first pulley. The first pulley and the second pulley cooperate with a synchronous belt.
[0007] Furthermore, the pump suction assembly also includes two turntables, each turntable being fixedly connected to a corresponding rotating shaft, and an intermediate shaft being fixedly connected between the two turntables. The air cylinder is slidably connected to a piston, and the piston is fixedly connected to a fixing rod. The fixing rod and the intermediate shaft are rotatably connected through the drive arm, and the air cylinder and the outer shell are fixedly connected through a first pipe.
[0008] Furthermore, the coarse detection component also includes a hollow coarse detection block, which is fixedly connected to the inner top wall of the outer shell. The coarse detection block and the air cylinder are connected through a second pipe, and the coarse detection block and the air storage tank are connected through a third pipe. A first detector is fixedly connected to the inner top wall of the coarse detection block. A first solenoid valve is installed inside the second pipe. The air storage tank and the outer shell are connected through multiple fourth pipes, and a second solenoid valve is installed inside each of the fourth pipes.
[0009] Furthermore, the fine detection component also includes a fine detection block, which is slidably and sealed within the detection cylinder. A second detector is fixedly embedded in the fine detection block, and the fine detection block has multiple air holes. A fourth solenoid valve is installed in each air hole. A fixing plate is fixedly connected to the inner side wall of the detection cylinder, and a second spring is fixedly connected between the fine detection block and the fixing plate. A fifth tube is fixedly connected through the air cylinder, the detection cylinder, and the outer shell, and the fifth tube connects the air cylinder and the detection cylinder. A third solenoid valve is installed inside the fifth tube.
[0010] Furthermore, the control component also includes a lifting plate, which is slidably and sealed within the gas storage tank. Multiple first springs are fixedly connected between the lifting plate and the top wall of the gas storage tank. The adjusting plate is slidably connected to two opposing inner side walls of the gas storage tank. The delay switch is electrically connected to the first solenoid valve, the second solenoid valve, the third solenoid valve, the fourth solenoid valve, and the second detector via wires.
[0011] Furthermore, one-way valves are installed in the first, second, and fifth pipes.
[0012] Furthermore, an adjusting wheel is fixedly connected to one end of the screw located outside the housing. The adjusting wheel is made of polyethylene and has anti-slip textures engraved on its sidewall.
[0013] Furthermore, multiple guide plates are fixedly connected to the upper surface of the adjustment plate, and the guide plates are slidably connected to the air storage box and the outer shell. One of the guide plates has scale lines sprayed on its side wall.
[0014] Furthermore, the outer casing has multiple heat dissipation holes on its sidewalls.
[0015] The present invention has the following advantages: 1. The dual-motor control dual-track walking method ensures good passability and makes the robot's walking and turning more flexible. 2. By reciprocating up and down of the piston, gas is drawn into the gas cylinder and then pumped into the coarse detection block. The gas is then detected by the first detector. Gas detection is performed in a closed space, which is more accurate than the method of directly using an external detector. 3. After a certain amount of air is introduced, the piston will pump the gas into the detection cylinder, where it will be carefully detected by the second detector. This ensures the accuracy of the detailed detection. At the same time, the second detector does not work for a long time, which ensures its service life and greatly reduces costs. 4. Under the control of the control components, gas is continuously pumped into the gas storage tank. The incoming gas causes the lifting plate to slide upward until the lifting plate triggers the delay switch. At this time, the gas will be pumped into the detection cylinder for detailed detection. That is, after a rough detection after a certain period of time, a detailed detection can be performed automatically without manual operation, which greatly improves the automation level of the robot. 5. By rotating the adjusting wheel, the screw can be rotated, and the rotation of the screw can adjust the height of the adjusting plate. The height of the adjusting plate determines how much gas is collected before a detailed test is performed. This allows the frequency of detailed testing to be adjusted, making the robot suitable for different situations and thus more versatile. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Example, refer to Figures 1 to 8 A gas detection robot for industrial safety inspection includes a chassis 1 and a main control module 45. The main control module 45 can control the direction and speed of two servo motors 6, thereby controlling the robot's walking direction and walking speed. The main control module 45 is fixedly connected to the upper surface of the chassis 1. The upper surface and lower surface of the chassis 1 are respectively fixedly connected to the outer shell 2 and the bottom cover 3. A drive mechanism is provided at the chassis 1. The drive mechanism consists of a walking component and a pumping component. The walking component includes two rotating shafts 9, which are rotatably connected to two inner sidewalls opposite to the outer shell 2 via bearings. The pumping component includes an air cylinder 15, which is fixedly connected to the inner top wall of the outer shell 2. A detection mechanism is provided at the outer casing 2. The detection mechanism consists of a coarse detection component, a fine detection component, and a control component. The coarse detection component includes a hollow air storage box 24, which is fixedly connected to the inner top wall of the outer casing 2. The fine detection component includes a detection cylinder 34, which is fixedly connected to the inner top wall of the outer casing 2. The control component includes a support block 28, which is threadedly connected to a screw 29. The screw 29 is rotatably connected to an adjustment plate 30 through a bearing. A time delay switch 31 is fixedly connected to the lower surface of the adjustment plate 30. When the time delay switch 31 is pressed, it can be energized for a certain period of time and then automatically de-energized. This is existing technology and will not be described in detail here.
[0020] The walking assembly also includes two servo motors 6. The servo motors 6 are fixedly connected to the two inner side walls opposite to the chassis 1. The two inner side walls opposite to each other on the chassis 1 are rotatably connected to a drive shaft 7 and a wheel 4 via bearings. The drive shaft 7 is fixedly connected to the output shaft of the corresponding servo motor 6. The end of the drive shaft 7 away from the servo motor 6 is fixedly connected to a drive wheel 5. The drive wheel 5 and the wheel 4 on the same side cooperate with the track 8. One drive shaft 7 is fixedly connected to a second pulley 11. One wheel 9 is fixedly connected to a first pulley 10. The first pulley 10 and the second pulley 11 cooperate with a synchronous belt 12.
[0021] The pump suction assembly also includes two turntables 13, which are fixedly connected to corresponding rotating shafts 9. An intermediate shaft 14 is fixedly connected between the two turntables 13. A piston 16 is slidably connected to the air cylinder 15. A fixed rod 17 is fixedly connected to the piston 16. The fixed rod 17 and the intermediate shaft 14 are rotatably connected to the drive arm 18. The fixed rod 17 and the intermediate shaft 14 are rotatably connected to the drive arm 18 through bearings. A first pipe 19 is fixedly connected to the air cylinder 15 and the outer shell 2.
[0022] The coarse detection assembly also includes a hollow coarse detection block 21, which is fixedly connected to the inner top wall of the outer shell 2. A second pipe 20 is fixedly connected to the coarse detection block 21 and the air cylinder 15. A third pipe 22 is fixedly connected to the coarse detection block 21 and the air storage tank 24. A first detector 23 is fixedly connected to the inner top wall of the coarse detection block 21. The first detector 23 is a simple gas sensor, which can only perform simple detection of gas components and detect dangerous gases, but cannot accurately measure the content. Its manufacturing cost is low. A first solenoid valve 41 is installed inside the second pipe 20. Multiple fourth pipes 25 are fixedly connected to the air storage tank 24 and the outer shell 2. A second solenoid valve 42 is installed inside each fourth pipe 25. During the detection process, the servo motor 6 rotates, driving the drive shaft 7 to rotate. The rotation of the drive shaft 7 drives the drive wheel 5 to rotate, which in turn drives the track 8 to move. The robot walks by means of a drive shaft 7, which rotates shaft 9 via the transmission of the first pulley 10, the second pulley 11, and the synchronous belt 12. The rotation of shaft 9 drives turntable 13 to rotate and, through drive arm 18, causes piston 16 to move up and down. When piston 16 moves downward, it draws external gas into air cylinder 15 through first pipe 19. When piston 16 moves upward, it pumps the drawn-in gas into coarse detection block 21 through second pipe 20. After passing through coarse detection block 21, the gas enters air storage tank 24 through third pipe 22. After the gas enters air storage tank 24, it causes lifting plate 26 to rise to a certain height. When the gas passes through coarse detection block 21, first detector 23 performs a rough detection on the gas and pumps the gas into the sealed coarse detection block 21 for further detection. Compared with direct detection through the outside of the detector, this greatly improves the accuracy of the detection.
[0023] The fine detection component also includes a fine detection block 36, which is slidably and sealed within the detection cylinder 34. A second detector 37 is fixedly embedded in the fine detection block 36. The second detector 37 is a precision gas sensor that can precisely detect the composition and content of gas. It has a high manufacturing cost. The fine detection block 36 has multiple air holes 40, and a fourth solenoid valve 44 is installed in each air hole 40. A fixing plate 38 is fixedly connected to the inner side wall of the detection cylinder 34. A second spring 39 is fixedly connected between the fine detection block 36 and the fixing plate 38. A fifth tube 35 is fixedly connected through the air cylinder 15, the detection cylinder 34, and the outer shell 2. The fifth tube 35 connects the air cylinder 15 and the detection cylinder 34. A third solenoid valve 43 is installed in the fifth tube 35.
[0024] The control assembly also includes a lifting plate 26, which is slidably and sealed within the air storage tank 24. Multiple first springs 27 are fixedly connected between the lifting plate 26 and the top wall of the air storage tank 24. An adjusting plate 30 is slidably connected to two opposing inner walls of the air storage tank 24. A delay switch 31 is electrically connected to the first solenoid valve 41, the second solenoid valve 42, the third solenoid valve 43, the fourth solenoid valve 44, and the second detector 37 via wires. The first and fourth solenoid valves 41 and 44 are normally open solenoid valves, closing when energized, while the third and second solenoid valves 43 and 42 are normally closed solenoid valves, opening when energized. That is, when energized, the first and fourth solenoid valves 41 and 44 close, and the third and second solenoid valves 43 and 42 open. As the robot moves continuously, gas is continuously pumped into the air storage tank 24, causing the lifting plate 26 to rise until it contacts the delay switch 31, at which point the delay switch 31 is deactivated. When pressed, the first solenoid valve 41 and the fourth solenoid valve 44 are energized and closed, while the third solenoid valve 43 and the second solenoid valve 42 are energized and opened. After the second solenoid valve 42 is energized and opened, under the elastic force of the first spring 27, the lifting plate 26 is reset and the gas accumulated in the gas storage tank 24 is discharged through the fourth pipe 25. After the third solenoid valve 43 is energized and opened, the piston 16 slides up and pumps the gas into the detection cylinder 34 through the fifth pipe 35. Since the fourth solenoid valve 44 is closed at this time, the gas entering the detection cylinder 34 will not be discharged, but will accumulate in the detection cylinder 34. At this time, the second detector 37 is energized and working, and performs precise detection on the accumulated gas, and performs detailed detection on the composition and content. That is, the robot can perform periodic detailed detection, rather than keeping the precision detector working for a long time, which greatly improves the service life of the precision detector, while ensuring the accuracy of the detection.
[0025] One-way valves are installed in the first pipe 19, the second pipe 20, and the fifth pipe 35. The one-way valve in the first pipe 19 only allows gas to enter the air cylinder 15 from the outside. The one-way valve in the second pipe 20 only allows air to enter the detection block 21 from the air cylinder 15. The one-way valve in the fifth pipe 35 only allows gas to enter the detection cylinder 34 from the one-way valve in the air cylinder 15. The one-way valves ensure the correct flow direction of the gas.
[0026] An adjusting wheel 32 is fixedly connected to one end of the screw 29 located outside the housing 2. The adjusting wheel 32 is made of polyethylene and has anti-slip textures engraved on its side wall. The anti-slip textures prevent slippage during operation of the adjusting wheel 32 and ensure operational stability.
[0027] Multiple guide plates 33 are fixedly connected to the upper surface of the adjusting plate 30. The guide plates 33 are slidably connected to the air storage box 24 and the outer shell 2. The guide plates 33 ensure the stable up-and-down sliding of the adjusting plate 30 and prevent it from tilting, thus ensuring the smooth operation of the robot. One of the guide plates 33 has scale lines sprayed on its side wall (e.g., Figure 5 As shown in the figure, the position of the adjustment plate 30 can be precisely adjusted according to the indication of the scale lines, thereby precisely adjusting the frequency of fine detection.
[0028] Multiple heat dissipation holes are provided on the side walls of the outer casing 2. The opening of the heat dissipation holes facilitates the heat dissipation of the main control module 45 and ensures its stable working environment.
[0029] In this invention, the robot is placed in the environment to be detected and its walking path is set. The main control module 45 can control the robot's walking speed and direction by controlling the rotation speed and steering of the two servo motors 6, so that the robot walks along the set route.
[0030] Then, the adjustment wheel 32 is rotated according to the required fine detection frequency. The rotation of the adjustment wheel 32 drives the screw 29 to rotate, and the rotation of the screw 29 will drive the adjustment plate 30 to move up and down, thereby adjusting the distance between the adjustment plate 30 and the lifting plate 26, thus adjusting how much gas is accumulated before fine detection is performed. Since the servo motor 6 drives the robot to walk and the piston 16 to pump air at the same time, the fine detection frequency can be adjusted after adjusting the amount of accumulated gas.
[0031] After adjustment and setup, the robot is placed and testing begins. During testing, the servo motor 6 rotates, driving the drive shaft 7 to rotate. The drive shaft 7 then drives the drive wheel 5 to rotate, which in turn drives the track 8 to move, thus enabling the robot to walk. During walking, the drive shaft 7, through the transmission of the first pulley 10, the second pulley 11, and the synchronous belt 12, causes the rotating shaft 9 to rotate. The rotating shaft 9 drives the turntable 13 to rotate, and through the drive arm 18, causes the piston 16 to move up and down reciprocally. When the piston 16 moves downward, it draws external gas into the air cylinder 15 through the first pipe 19. When the piston 16 moves upward, it pumps the drawn-in gas into the coarse detection block 21 through the second pipe 20. After passing through the coarse detection block 21, the gas enters the air storage tank 24 through the third pipe 22. After the gas enters the air storage tank 24, it causes the lifting plate 26 to rise to a certain height. When the gas passes through the coarse detection block 21, the first detector 23 performs a rough detection on the passing gas.
[0032] As the robot continues to move, gas is continuously pumped into the gas storage tank 24, and the lifting plate 26 rises continuously until it contacts the delay switch 31. At this time, the delay switch 31 is pressed, the first solenoid valve 41 and the fourth solenoid valve 44 are energized and closed, while the third solenoid valve 43 and the second solenoid valve 42 are energized and opened. After the second solenoid valve 42 is energized and opened, the lifting plate 26 is reset under the elastic force of the first spring 27, and the gas accumulated in the gas storage tank 24 is discharged through the fourth pipe 25.
[0033] When the third solenoid valve 43 is energized and opened, the piston 16 slides up and pumps the gas into the detection cylinder 34 through the fifth pipe 35. Since the fourth solenoid valve 44 is closed at this time, the gas entering the detection cylinder 34 will not be discharged, but will accumulate in the detection cylinder 34. At this time, the second detector 37 is energized and working, and performs precise detection on the accumulated gas, and performs detailed detection on its composition and content.
[0034] After a certain period of time, the first solenoid valve 41 and the fourth solenoid valve 44 are de-energized and opened, the second solenoid valve 42 and the third solenoid valve 43 are de-energized and closed, and after the fourth solenoid valve 44 opens, the fine detection block 36 is reset under the elastic force of the second spring 39, and the gas in the detection cylinder 35 is discharged. At the same time, the first solenoid valve 41 is energized and opened, and the gas will enter the coarse detection block 21 again through the second pipe 20 to continue the coarse detection. This cycle repeats to complete the gas detection in the area.
[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
