Description

Technical Field

[0001] The utility model relates to the technical field of flammable and explosive gas monitoring, and particularly relates to a safety monitoring device for flammable and explosive gases. Background Art

[0002] The flammable and explosive gas monitoring system is mainly used to monitor the leakage situation in dangerous places in the production working environment in real time. It is an important instrument for ensuring safe production. When the flammable and explosive gas in the monitored environment leaks during production and use and the concentration reaches the alarm set value, the detector immediately emits sound and light alarm signals to remind to take safety measures as early as possible to avoid the occurrence of production accidents, and plays an important role in ensuring the safety monitoring and control of green petrochemical.

[0003] However, most of the flammable and explosive gas monitoring devices are fixed, which is not convenient to automatically adjust the height and angle. For a large number of flammable and explosive gases set and used, they are not in the same position. If there is a lack of a flammable and explosive gas monitor that is convenient to automatically adjust the height and angle, it will bring a lot of inconvenience in actual use and also reduce the use effect to a certain extent. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a safety monitoring device for flammable and explosive gases to solve at least any one of the problems mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A safety monitoring device for flammable and explosive gases, including a base, the four sides of the bottom of the base are all rotatably connected by bearings with universal wheels, and the universal wheels are all set as universal wheels with self-locking functions. A lifting component is arranged on the top of the base, a rotating component is arranged on the front of the lifting component, and a monitoring component is detachably connected to the top of the rotating component.

[0006] Preferably, the lifting component includes a connecting seat fixedly connected to the top of the base. Slide rails are provided on both sides of the inner wall of the connecting seat. A first motor is arranged on the top of the connecting seat. The output end of the first motor is sleeved with a lead screw through a coupling. A fixing plate is sleeved in the middle of the lead screw. A lead screw groove adapted to the lead screw is provided through the top of the fixing plate. Sliders are fixedly connected to both sides of the fixing plate.

[0007] Preferably, the fixing plate is sleeved in the middle of the lead screw through the lead screw groove and is slidably connected to the connecting seat through the sliders in the slide rails.

[0008] Preferably, the rotating assembly includes a square seat fixedly connected to the front surface of the fixed plate. A second motor is provided at the bottom of the square seat. A circular ring is provided at the top of the output shaft of the second motor. Two first threaded holes are provided at the top of the circular ring.

[0009] Preferably, the output shaft of the second motor passes through the bottom of the square seat and extends to the top to be fixedly connected to the bottom of the circular ring.

[0010] Preferably, the monitoring assembly includes a connecting plate detachably connected to the top of the circular ring. Two second threaded holes of the same size as the first threaded holes are provided through the top of the connecting plate. Fixing bolts are threadedly connected to the inner cavities of the second threaded holes and the first threaded holes. An inflammable and explosive gas monitor is provided at the top of the connecting plate. A delivery pipe is threadedly connected to the left side of the inflammable and explosive gas monitor. An air extractor is fixedly connected to the left side of the delivery pipe.

[0011] Preferably, the connecting plate is detachably connected to the circular ring through the fixing bolts in the inner cavities of the second threaded holes and the first threaded holes.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. In the present utility model, the output end of the first motor drives the lead screw to rotate. When the lead screw rotates, it drives the fixed plate to slide up and down in the slide rail through the lead screw groove and the slider. When sliding, it drives the inflammable and explosive gas monitor to move together. Thus, the device can prevent unnecessary impacts caused by the inability to quickly monitor when the position of the inflammable and explosive gas is too high. When it is necessary to adjust the monitoring angle, the output shaft of the second motor drives the circular ring to rotate. When rotating, it drives the inflammable and explosive gas monitor to rotate together, and the angle can be automatically adjusted during the operation and monitoring of the inflammable and explosive gas monitor, so as to monitor the inflammable and explosive gas at different angular positions and perform diverse uses.

[0014] 2. In the present utility model, the air extractor sucks the gas and enters the inflammable and explosive gas monitor through the delivery pipe for identification, which can quickly monitor the air containing inflammable and explosive gas by suction without the need for the inflammable and explosive gas to come into contact with the inflammable and explosive gas monitor before monitoring. And by separating the air extractor from the inflammable and explosive gas monitor counterclockwise through the delivery pipe, and then removing the fixing bolts counterclockwise in the first threaded hole and the second threaded hole to release its fixation with the circular ring, the inflammable and explosive gas monitor can be removed, so as to quickly monitor the inflammable and explosive gas by suction and perform disassembly, repair, replacement and cleaning of the inflammable and explosive gas monitor.

[0022] The present utility model provides a Figures 1-5 flammable and explosive gas safety monitoring device as shown, including a base 1. Universal wheels 2 are rotatably connected to the four peripheries of the bottom of the base 1 through bearings. The universal wheels 2 are all provided with self-locking functions. A lifting component is arranged on the top of the base 1, a rotating component is arranged on the front of the lifting component, and a monitoring component is detachably connected to the top of the rotating component.

[0023] Furthermore, the lifting component includes a connecting seat 3 fixedly connected to the top of the base 1. Slide rails 4 are provided on both sides of the inner wall of the connecting seat 3. A first motor 5 is arranged on the top of the connecting seat 3. A lead screw 6 is sleeved on the output end of the first motor 5 through a coupling. A fixing plate 7 is sleeved in the middle of the lead screw 6. A lead screw groove 8 adapted to the lead screw 6 is formed through the top of the fixing plate 7. Sliders 9 are fixedly connected to both sides of the fixing plate 7. The fixing plate 7 is sleeved in the middle of the lead screw 6 through the lead screw groove 8 and is slidably connected to the connecting seat 3 through the sliders 9 in the slide rails 4. By providing the lifting component, it is convenient for the user to automatically adjust the height during the operation of the inflammable and explosive gas monitor 17, so as to prevent unnecessary influence caused by the inability to quickly monitor when the position of the inflammable and explosive gas is too high.

[0024] Furthermore, the rotating component includes a square seat 10 fixedly connected to the front of the fixing plate 7. A second motor 11 is arranged at the bottom of the square seat 10. A circular ring 12 is arranged at the top of the output shaft of the second motor 11. Two first threaded holes 13 are formed in the top of the circular ring 12. The output shaft of the second motor 11 passes through the bottom of the square seat 10 and extends to the top to be fixedly connected to the bottom of the circular ring 12. By providing the rotating component, it is convenient for the user to automatically adjust the angle during the operation and monitoring of the inflammable and explosive gas monitor 17, so as to monitor the inflammable and explosive gas at different angular positions and perform various uses.

[0025] Furthermore, the monitoring component includes a connecting plate 14 detachably connected to the top of the circular ring 12. Two second threaded holes 15 of the same size as the first threaded holes 13 are formed through the top of the connecting plate 14. Fixing bolts 16 are threadedly connected in the inner cavities of the second threaded holes 15 and the first threaded holes 13. An inflammable and explosive gas monitor 17 is arranged on the top of the connecting plate 14. A delivery pipe 18 is threadedly connected to the left side of the inflammable and explosive gas monitor 17. An air extractor 19 is fixedly connected to the left side of the delivery pipe 18.

[0026] When the utility model is specifically implemented, when it is necessary to adjust the monitoring height, the output end of the first motor 5 drives the lead screw 6 to rotate. When the lead screw 6 rotates, it drives the fixed plate 7 through the lead screw groove 8 to slide up and down in the slide rail 4 through the slider 9. When sliding, the flammable and explosive gas monitor 17 is driven to move together. Therefore, the device can prevent unnecessary influence caused by the inability to quickly monitor when the position of the flammable and explosive gas is too high; when it is necessary to adjust the monitoring angle, the output shaft of the second motor 11 drives the ring 12 to rotate. When rotating, the flammable and explosive gas monitor 17 is driven to rotate together, and the angle can be automatically adjusted during the operation and monitoring of the flammable and explosive gas monitor 17. Therefore, the flammable and explosive gas at different angular positions can be monitored and used in various ways. After the height and angle are adjusted, the air is sucked by the air extractor 19 and enters the flammable and explosive gas monitor 17 through the delivery pipe 18 for identification. The air containing flammable and explosive gas can be quickly monitored by suction, without the need for the flammable and explosive gas to contact the flammable and explosive gas monitor 17 before monitoring. Then, the air extractor 19 is separated from the flammable and explosive gas monitor 17 by rotating counterclockwise through the delivery pipe 18. Subsequently, the fixing bolt 16 is rotated counterclockwise and removed from the first threaded hole 13 and the second threaded hole 15 to release its fixation with the ring 12, and the flammable and explosive gas monitor 17 can be removed. Therefore, the flammable and explosive gas can be quickly monitored by suction, and the flammable and explosive gas monitor 17 can be disassembled, repaired, replaced, and cleaned.
