Description

Technical Field

[0001] This utility model relates to the field of petrochemical technology, and more specifically, it relates to an intelligent early warning and detection device for construction sites in the petrochemical industry. Background Technology

[0002] Petrochemical industry refers to the industrial sector that uses petroleum and natural gas as raw materials to produce a wide range of petroleum and chemical products, including gasoline, diesel, lubricating oil, plastics, rubber, and chemical fibers, through a series of chemical processing processes. It occupies a key position in the national economy. Petrochemical construction sites face numerous risks, such as equipment failure, material leakage, and violations of regulations. If these risks get out of control, they may lead to serious accidents such as fires, explosions, and poisoning. Therefore, it is necessary to conduct intelligent early warning detection at construction sites to detect potential dangers in advance and issue alarms to ensure construction safety and stable operation.

[0003] However, existing intelligent early warning and detection devices at construction sites mostly use fixed single sensors for detection. For example, various detection sensors (such as combustible gas sensors, temperature sensors, etc.) are rigidly fixed to specific points in the construction area using simple brackets. This fixing method is prone to dynamic changes in the layout of equipment and materials at the construction site, and the fixed sensor is difficult to adjust the detection position and angle flexibly. This results in incomplete detection coverage of some key areas (such as temporary material storage areas and temporary equipment maintenance areas), and blind spots in hazard monitoring are likely to occur.

[0005] In view of the above situation and to overcome the defects of the existing technology, this utility model provides an intelligent early warning and detection device for construction sites in the petrochemical industry, which aims to solve the problems in the background technology mentioned above.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this application provides the following technical solution: an intelligent early warning and detection device for construction sites in the petrochemical industry, comprising a top frame, with symmetrical first ball bearings fixedly connected to the inner walls of both ends of the top frame, and a threaded shaft fixedly connected to the inner rings of the two first ball bearings, a stepper motor fixedly connected to the right side of the top frame by bolts, the output end of the stepper motor fixedly connected to the right end of the threaded shaft, two balance shafts fixedly connected to one side of the top frame that is close to each other, a moving block threadedly connected to the outer surface of the threaded shaft, the interior of the moving block slidingly connected to the interior of the two balance shafts, an adjustment frame fixedly connected to the bottom surface of the moving block, two symmetrical second ball bearings fixedly connected to the inner wall of the adjustment frame, a servo motor fixedly connected to the right side of the adjustment frame by bolts, a drive shaft fixedly connected to the inner rings of the two second ball bearings, an adjustment disc fixedly connected to the outer surface of the drive shaft, the adjustment disc being located in the middle of the adjustment frame, and a combustible gas sensor fixedly connected to the outer surface of the adjustment disc.

[0008] The present invention is further configured such that the bottom surface of the top frame has two rolling grooves, the upper surface of the moving block has two roller grooves, the inner wall of each roller groove is fixedly connected to two symmetrical third ball bearings, the inner ring of each pair of third ball bearings is fixedly connected to a rolling wheel, and the outer surface of each rolling wheel is in rolling connection with the inside of the rolling groove.

[0009] The present invention is further configured such that limiting plates are fixedly connected to both the front and back of the adjustment frame, two baffles are fixedly connected to the outer surface of the adjustment plate, the combustible gas sensor is located in the middle of the two baffles, and the outer surface of one of the baffles is in contact with the limiting plate located on the front of the adjustment frame.

[0010] The present invention is further configured such that a plurality of telescopic sleeves are fixedly connected to the inner wall of the top of the top frame, and a telescopic cylinder is slidably connected inside each telescopic sleeve. A conical buffer spring is fixedly connected to the inner top wall of each telescopic cylinder and the inner bottom wall of the telescopic sleeve.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By cooperating with a stepper motor and a threaded shaft, the rotation of the threaded shaft can be precisely controlled when the stepper motor is running, thereby driving the moving block to move smoothly in a straight line along the balance shaft on the top frame. This allows for flexible adjustment of the horizontal position of the combustible gas sensor according to changes in the construction area, avoiding monitoring blind spots caused by fixed sensor positions. It enables comprehensive coverage detection of key areas on the construction site, such as temporary material storage points and temporary equipment maintenance areas. At the same time, the servo motor on the adjustment frame works in conjunction with the drive shaft and adjustment plate. The servo motor drives the drive shaft to rotate, which in turn drives the adjustment plate and the combustible gas sensor installed on it to adjust the angle. The detection angle of the sensor can be adjusted according to the actual situation such as the layout of equipment and pipeline routing on site, enhancing the monitoring of gas leaks in specific areas and accurately capturing potential gas leak hazards. This effectively makes up for the shortcomings of traditional fixed-installation sensors, which are difficult to adjust in a flexible manner and result in incomplete monitoring of some dangerous areas.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0025] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0026] Please see Figures 1-6 The system includes a top frame 1. Symmetrical first ball bearings 6 are fixedly connected to the inner walls of both ends of the top frame 1. A threaded shaft 5 is fixedly connected to the inner rings of the two first ball bearings 6. A stepper motor 13 is fixedly connected to the right side of the top frame 1 via bolts. The output end of the stepper motor 13 is fixedly connected to the right end of the threaded shaft 5. Two balance shafts 12 are fixedly connected to one side of the top frame 1 that is close to each other. A moving block 10 is threadedly connected to the outer surface of the threaded shaft 5. The interior of the moving block 10 is slidably connected to the interior of the two balance shafts 12. An adjusting frame 7 is fixedly connected to the bottom surface of the moving block 10. Two symmetric second ball bearings 22 are fixedly connected to the inner wall of the adjusting frame 7. A servo motor 11 is fixedly connected to the right side of the adjusting frame 7 via bolts. A drive shaft 21 is fixedly connected to the inner rings of the two second ball bearings 22. An adjusting disc 8 is fixedly connected to the outer surface of the drive shaft 21. The adjusting disc 8 is located in the middle of the adjusting frame 7. A combustible gas sensor 9 is fixedly connected to the outer surface of the adjusting disc 8.

[0027] Specifically, the stepper motor 13 drives the threaded shaft 5 to rotate within the two first ball bearings 6. When the threaded shaft 5 rotates, it engages with the moving block 10, causing the moving block 10 to slide smoothly along the two balance shafts 12. The moving block 10 drives the adjustment frame 7 and the combustible gas sensor 9 to move synchronously. At the same time, the servo motor 11 drives the drive shaft 21 to rotate within the two second ball bearings 22, causing the adjustment plate 8 and the combustible gas sensor 9 to adjust their angles. This enables flexible adjustment of the sensor position and angle, solves the monitoring blind spot problem caused by fixed installation, and improves the detection coverage.

[0028] Please see Figures 1-6The bottom surface of the top frame 1 has two rolling grooves 14, and the upper surface of the moving block 10 has two roller grooves 18. The inner wall of each roller groove 18 is fixedly connected to two symmetrical third ball bearings 19. The inner ring of each pair of third ball bearings 19 is fixedly connected to a roller 20. The outer surface of each roller 20 is in rolling connection with the inside of the rolling groove 14.

[0029] Specifically, when the moving block 10 moves, the third ball bearing 19 in its roller groove 18 supports the rolling wheel 20 to roll in the rolling groove 14 of the top frame 1. The rolling wheel 20 and the rolling groove 14 cooperate to reduce the friction when the moving block 10 slides, making the movement smoother and more stable. The balance shaft 12 further improves the stability of the movement, avoids the movement from jamming and affecting the sensor detection accuracy, and ensures the reliability of position adjustment.

[0030] Please see Figures 1-6 Limiting plates 23 are fixedly connected to both the front and back of the adjusting frame 7. Two baffles 24 are fixedly connected to the outer surface of the adjusting plate 8. The combustible gas sensor 9 is located in the middle of the two baffles 24. The outer surface of one of the baffles 24 is in contact with the limiting plate 23 located on the front of the adjusting frame 7.

[0031] Specifically, when the adjusting plate 8 drives the combustible gas sensor 9 to rotate, the baffle 24 on its outer surface rotates synchronously with the adjusting plate 8. When the baffle 24 contacts the limiting plate 23 on the adjusting frame 7, it restricts the adjusting plate 8 from continuing to rotate, thus avoiding damage to the components caused by excessive angle adjustment and ensuring the accuracy of the detection angle.

[0032] Please see Figures 1-6 Multiple telescopic sleeves 15 are fixedly connected to the inner wall of the top of the top frame 1. A telescopic cylinder 3 is slidably connected inside each telescopic sleeve 15. A conical buffer spring 17 is fixedly connected to the inner top wall of each telescopic cylinder 3 and the inner bottom wall of the telescopic sleeve 15. The top of each telescopic cylinder 3 protrudes from the horizontal line of the top frame 1. A damper 16 is fixedly connected to the inner bottom wall of each telescopic sleeve 15 and the inner top wall of the telescopic cylinder 3. Each damper 16 is located in the middle of the conical buffer spring 17.

[0033] Specifically, during the installation of the top frame 1, the top of the telescopic cylinder 3 contacts and is pressed against the installation surface, causing the telescopic cylinder 3 to retract into the telescopic sleeve 15. The conical buffer spring 17 is compressed to generate elastic force to buffer the pressure. The damper 16 moves with the telescopic cylinder 3 to generate damping force, which slows down the spring rebound speed. The two work together to absorb the vibration energy of the construction site, reduce the impact of vibration on the top frame 1 and the sensor, avoid the loosening and damage of components caused by long-term vibration, and extend the service life of the device.

[0034] Please see Figures 1-6 Each telescopic cylinder 3 has an anti-slip pad 2 fixedly connected to its top end, and two rubber pads 4 are fixedly connected to the upper surface of the top frame 1.

[0035] Specifically, the anti-slip pad 2 at the top of the telescopic cylinder 3 contacts the mounting surface, increasing friction to prevent the top frame 1 from sliding and shifting after installation, thus improving the stability of the device installation. The rubber pad 4 on the upper surface of the top frame 1 can buffer the impact force when the device is transported or subjected to external force collision, protecting the top frame 1 and the components above it, avoiding damage to the device caused by unstable installation or collision, and ensuring the stability of the overall structure.

[0036] Working principle:

[0037] In use, after the stepper motor 13 is started, its output end drives the threaded shaft 5 to rotate stably in the inner rings of the two first ball bearings 6. The threaded structure of the threaded shaft 5 and the moving block 10 cooperate with each other. At the same time, the moving block 10 slides along the two balance shafts 12 to realize the horizontal position adjustment of the moving block 10. During the movement, the third ball bearing 19 in the roller groove 18 of the moving block 10 supports the rolling wheel 20 to roll in the rolling groove 14 of the top frame 1, which greatly reduces the sliding friction and makes the movement smoother. The moving block 10 drives the adjusting frame 7 to move synchronously. The servo motor 11 on the adjusting frame 7 drives the drive shaft 21 to rotate in the two second ball bearings 22. The drive shaft 21 drives the adjusting plate 8 and The combustible gas sensor 9 rotates to adjust the detection angle. During adjustment, the baffle 24 of the adjusting plate 8 contacts the limiting plate 23 of the adjusting frame 7, limiting the excessive rotation of the adjusting plate 8. When the top frame 1 is installed, the telescopic cylinder 3 retracts into the telescopic sleeve 15 after being compressed. The conical buffer spring 17 is compressed to generate elastic force to buffer the pressure, and the damper 16 slows down the spring rebound speed. Together, they absorb the vibration of the construction site. The anti-slip pad 2 at the top of the telescopic cylinder 3 increases the friction with the installation surface to prevent the top frame 1 from shifting. The rubber pad 4 on the top frame 1 buffers the impact of external forces, realizing the flexible adjustment of the position and angle of the combustible gas sensor 9, eliminating the monitoring blind zone, reducing the impact of vibration and external forces on the device, and ensuring the stability and accuracy of the detection.

For all the fixed connections mentioned above, welding is preferred.
