Description

Technical Field

[0001] The present invention relates to the technical field of gas monitoring, in particular to a gas monitoring device for chemical safety. Background Art

[0002] Gas monitoring involves the quantitative or qualitative analysis of various gas components in the air using specialized instruments and methods. Gas detection systems are generally divided into a control unit, a sensor unit, and a management platform. They enable remote unattended operation, real-time data transmission, over-limit alarms, equipment linkage, and data analysis. A common gas monitoring device is a gas monitor, which can be used to detect gas leaks during chemical production processes, thereby ensuring personnel safety.

[0003] After searching, it was found that a gas monitor is disclosed in Chinese patent documents [Announcement No.: CN222671786U].

[0020] Preferably, a constant temperature layer is fixedly provided on the inner wall of the protective box, and the material of the constant temperature layer is thermal insulation cotton.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention provides a protective mechanism. When the remote-controlled vehicle drives the gas monitor to move, air enters the protective box from the air inlet. The sensor probe then senses whether there is a chemical gas leak. At the same time, the dustproof net isolates the dust, thereby preventing dust from being adsorbed on the surface of the sensor probe and improving the monitoring accuracy.

[0023] 2. The present invention is provided with a dust cleaning mechanism. When dust accumulates on the dustproof net, the motor is started, and the motor drives the worm to rotate. Since the worm is meshed with the worm wheel, the worm wheel rotates synchronously with the worm. When the worm wheel rotates, it drives the lead screw to rotate around the bearing. The lead screw drives the transmission block to move back and forth left and right. The L-shaped block, the support block and the brush roller move back and forth synchronously with the transmission block. When the brush roller moves back and forth, it removes the dust on the surface of the dustproof net to prevent dust from accumulating on the surface of the dustproof net, thereby improving the accuracy of monitoring.

[0024] 3. The present invention is provided with a vibration mechanism, so that when the transmission block drives the L-shaped block to move back and forth, the extrusion rod in the vibration mechanism will also move back and forth synchronously. When the arc-shaped part of the extrusion rod contacts the slope part of the extrusion block, the extrusion rod is affected by the extrusion, which will drive the rebound block, the sliding block and the knocking rod to move to the side close to the reset spring, and compress the reset spring at the same time. When the extrusion rod moves to no longer contact the extrusion block, the elastic force generated by the reset spring will push the rebound block to reset suddenly, and the sliding block and the knocking rod will also move synchronously, so that one end of the sliding rod will knock on the vibration block to generate vibration. After that, the vibration force will be transmitted to the brush roller through the support block, and the dust adhering to the surface of the brush roller will be shaken off, so as to prevent the dust from adhering to the surface of the dustproof net again, thereby improving the monitoring accuracy.

[0025] 4. The present invention is provided with an air collecting mechanism, which can drive the push rod, push block and piston plate to move while the rebound block moves toward the side close to the return spring. The piston plate will compress the gas in the air collecting cylinder. When the air pressure in the air collecting cylinder is greater than the limit of the one-way pressure valve, the gas will be ejected from the exhaust pipe, and then pass through the C-shaped box and evenly sprayed on the surface of the brush roller by multiple air injection pipes. When the elastic force generated by the return spring pushes the rebound block to move to the side away from the return spring, the push rod, push block and piston plate will move synchronously with the rebound block. At this time, the air collecting cylinder is under negative pressure, and the gas will enter the interior of the air collecting cylinder through the air inlet pipe, and spray the gas to the surface of the brush roller intermittently in a cycle, so as to effectively blow off the dust and prevent the dust from adhering to the dustproof net again, thereby improving the monitoring accuracy.

[0026] 5. In the present invention, by setting up a protective mechanism, when the remote-controlled vehicle drives the gas monitor to move, air will enter the protective box from the air inlet, and then the sensor probe will be used to sense whether there is a chemical gas leak. At the same time, the dust net will isolate the dust, thereby avoiding the adsorption of dust on the surface of the sensor probe, thereby improving the accuracy of monitoring. At the same time, the cleaning mechanism can move back and forth through the brush roller to remove the dust on the surface of the dust net, and the vibration mechanism and the gas collection mechanism can remove the dust adhering to the brush roller, thereby improving the cleaning effect and further improving the accuracy of monitoring.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] See also Figure 1 - Figure 10 As shown,

[0040] Example 1:

[0041] A gas monitoring device for chemical safety, comprising a remote-controlled vehicle 1 and a gas monitor 2. The gas monitor 2 is fixedly mounted on one side of the remote-controlled vehicle 1. A sensor probe 3 is fixedly mounted on the bottom of the gas monitor 2. A mounting post 4 is fixedly connected to the top of the remote-controlled vehicle 1. Cameras 5 are fixedly mounted on both sides of the mounting post 4. A lighting lamp 6 is fixedly mounted on the top of the camera 5. A protective mechanism is provided on the bottom of the remote-controlled vehicle 1.

[0042] The protective mechanism includes a protective box 7 fixedly connected to one side of the remote control car 1, the sensor probe 3 is located inside the protective box 7, an air inlet 8 is opened at the bottom of the protective box 7, a dustproof net 9 is fixedly connected to the inner wall of the air inlet 8, and a protective shell 10 is fixedly connected to one side of the protective box 7.

[0043] In this embodiment, in order to make the gas monitor 2 more flexible in use, the gas monitor 2 will be installed on the remote control car 1, and the monitor will be moved by the remote control car 1 to monitor whether the gas is leaking. During the movement of the remote control car 1, dust is easily raised and adsorbed on the surface of the sensor probe 3, thereby affecting the accuracy of the detection. Therefore, by setting up a protective mechanism, when the remote control car 1 drives the gas monitor 2 to move, air will enter the protective box 7 from the air inlet 8, and then sense whether there is a chemical gas leak through the sensor probe 3. At the same time, the dustproof net 9 will isolate the dust, thereby avoiding the adsorption of dust on the surface of the sensor probe 3, thereby improving the accuracy of monitoring.

[0044] A constant temperature layer 39 is fixedly provided on the inner wall of the protection box 7, and the material of the constant temperature layer 39 is thermal insulation cotton.

[0045] In this embodiment, by providing the constant temperature layer 39, it is possible to avoid excessive temperature differences when air enters the protective box 7, thereby improving the accuracy of monitoring.

[0046] Example 2:

[0047] On the basis of the first embodiment, the protection mechanism in this embodiment can isolate the dust on the dustproof net 9. However, if a large amount of dust accumulates on the dustproof net 9, it will cause the air to be unable to enter the protection box 7 for detection, which will also affect the accuracy of monitoring. The present application also includes a dust cleaning mechanism, which is fixedly arranged on the protective shell 10.

[0048] The cleaning mechanism includes a motor 11 fixedly connected to one side of the protective shell 10, the output end of the motor 11 passes through the interior of the protective shell 10, and is fixedly connected to a worm 12, the bottom of the worm 12 is meshed with a worm wheel 13, and both sides of the worm wheel 13 are fixedly connected to a screw rod 14, one end of the screw rod 14 is rotatably connected to the inner wall of the protective shell 10 through a bearing, the surface of the screw rod 14 is transmission-connected to a transmission block 15, the bottom of the transmission block 15 is fixedly connected to an L-shaped block 16, one side of the L-shaped block 16 is fixedly connected to a support block 17, and one side of the support block 17 is fixedly connected to a brush roller 18.

[0049] In this embodiment, a dust cleaning mechanism is provided. When dust accumulates on the dustproof net 9, by starting the motor 11, the motor 11 will drive the worm 12 to rotate. Since the worm 12 is engaged with the worm wheel 13, the worm wheel 13 will rotate synchronously with the worm 12. When the worm wheel 13 rotates, it will drive the screw 14 to rotate around the bearing. The screw 14 will drive the transmission block 15 to move back and forth left and right. The L-shaped block 16, the support block 17 and the brush roller 18 will move back and forth synchronously with the transmission block 15. When the brush roller 18 moves back and forth, it will remove the dust on the surface of the dustproof net 9 to prevent dust from accumulating on the surface of the dustproof net 9, thereby improving the monitoring accuracy.

[0050] Example 3:

[0051] On the basis of the second embodiment, the cleaning mechanism in this embodiment removes the dust on the surface of the dustproof net 9 by making the brush roller 18 move back and forth, thereby improving the monitoring accuracy. However, considering that in the process of the brush roller 18 cleaning the dust, some dust will adhere to the surface of the brush roller 18, and in the process of the reciprocating movement of the brush roller 18, the dust will re-adhere to the surface of the dustproof net 9, thereby affecting the monitoring accuracy. The present application also includes a vibration mechanism including a reset spring 19 fixedly connected to one side of the L-shaped block 16, one side of the reset spring 19 is fixedly connected to a rebound block 20, the bottom of the rebound block 20 is fixedly connected to a sliding block 21, one side of the sliding block 21 is fixedly connected to a knocking rod 22, one side of the rebound block 20 is fixedly connected to an extrusion rod 23, and one side of the protective box 7 is fixedly connected to a plurality of extrusion blocks 24 used in conjunction with the extrusion rod 23;

[0052] A vibration block 25 is movably provided at one end of the knocking rod 22 . A vibration spring 26 is fixedly connected to one side of the vibration block 25 . One side of the vibration spring 26 is fixedly connected to one side of the support block 17 .

[0053] In this embodiment, by setting a vibration mechanism, while the transmission block 15 drives the L-shaped block 16 to move back and forth, the extrusion rod 23 in the vibration mechanism will also move back and forth synchronously. Figure 10 As shown, when the arc-shaped part of the extrusion rod 23 contacts the slope part of the extrusion block 24, the extrusion rod 23 is affected by the extrusion, which will drive the rebound block 20, the sliding block 21 and the knocking rod 22 to move toward the side close to the reset spring 19, and compress the reset spring 19 at the same time. When the extrusion rod 23 moves to no longer contact the extrusion block 24, the elastic force generated by the reset spring 19 will push the rebound block 20 to reset suddenly, and the sliding block 21 and the knocking rod 22 will also move synchronously, so that one end of the sliding rod knocks on the vibration block 25 to generate vibration. After that, the vibration force will be transmitted to the brush roller 18 through the support block 17, and the dust adhered to the surface of the brush roller 18 will be shaken off to prevent the dust from adhering to the surface of the dustproof net 9 again, thereby improving the monitoring accuracy.

[0054] A sliding groove 38 is defined at the bottom of the L-shaped block 16 , and the sliding groove 38 cooperates with the sliding block 21 .

[0055] In this embodiment, by setting the sliding groove 38, the rebound block 20, the sliding block 21 and the knocking rod 22 can be limited. When the extrusion rod 23 contacts the extrusion block 24, the structures such as the rebound block 20, the sliding block 21 and the knocking rod 22 are restricted to move only along the trajectory of the sliding groove 38, while improving their stability during the movement process.

[0056] One end of the extrusion rod 23 is spherical, and both sides of the extrusion block 24 are sloped.

[0057] In this embodiment, by providing an extrusion rod 23 and an extrusion block 24, when the arc-shaped portion of the extrusion rod 23 contacts the slope portion of the extrusion block 24, the extrusion rod 23 is affected by the extrusion, and will drive the rebound block 20, the sliding block 21 and the knocking rod 22 to move toward the side close to the return spring 19, thereby playing a transmission role.

[0058] Example 4:

[0059] On the basis of the first embodiment, the vibration mechanism in this embodiment can shake off the dust adhering to the surface of the brush roller 18 by generating a vibration force, thereby preventing the dust from adhering to the surface of the dustproof net 9 again during the cleaning process of the brush roller 18. However, considering that only most of the dust can be shaken off by vibration, some fine dust cannot still adhere to the surface of the brush roller 18. The present application also includes an air collecting mechanism, which is fixedly arranged on one side of the L-shaped block 16;

[0060] The gas collecting mechanism includes a gas collecting cylinder 27 fixedly connected to one side of the L-shaped block 16. The top of the gas collecting cylinder 27 is fixedly connected to an air inlet pipe 28. One side of the gas collecting cylinder 27 is fixedly connected to an exhaust pipe 29. One end of the exhaust pipe 29 is fixedly connected to a C-shaped box 30. One side of the C-shaped box 30 is fixedly connected to an injection pipe 31. The C-shaped box 30 is fixedly connected to the support block 17 via a connecting block 32.

[0061] A push rod 33 is fixedly connected to one side of the rebound block 20 . One end of the push rod 33 passes through the interior of the gas collecting cylinder 27 and is fixedly connected to a push block 34 .

[0062] When the air pressure in the air collecting cylinder 27 exceeds the limit of the one-way pressure valve 36, the gas will be ejected from the exhaust pipe 29, and then passed through the C-shaped box 30 and evenly sprayed on the surface of the brush roller 18 by multiple injection pipes 31. When the elastic force generated by the return spring 19 pushes the rebound block 20 to move to the side away from the return spring 19, the push rod 33, the push block 34 and the piston plate 37 will move synchronously with the rebound block 20. At this time, there is negative pressure in the air collecting cylinder 27, and the gas will enter the interior of the air collecting cylinder 27 from the air inlet pipe 28, and spray the gas to the surface of the brush roller 18 intermittently in a cycle, effectively blowing off the dust and preventing the dust from adhering to the dustproof net 9 again, thereby improving the monitoring accuracy.

[0063] A one-way valve 35 is fixedly mounted on the surface of the intake pipe 28 , and a one-way pressure valve 36 is fixedly mounted on the surface of the exhaust pipe 29 .

[0064] In this embodiment, a one-way valve 35 and a one-way pressure valve 36 are provided. The one-way valve 35 is a valve that can only allow air to enter the gas collecting cylinder 27, and the one-way pressure valve 36 is a valve that can only allow air to enter the exhaust pipe 29. Therefore, when the gas collecting cylinder 27 is under negative pressure, the gas will enter the gas collecting cylinder 27 through the intake pipe 28. When the gas in the gas collecting cylinder 27 is squeezed, the gas can only be discharged through the exhaust pipe 29.

[0065] One side of the pushing block 34 is fixedly connected to a piston plate 37 , which is made of rubber.

[0066] In this embodiment, by providing a piston plate 37, the sealing performance inside the gas collecting cylinder 27 can be improved, so that a closed cavity is formed inside the gas collecting cylinder 27. When the piston plate 37 moves back and forth, the gas inside the gas collecting cylinder 27 is compressed.

[0067] There are a plurality of air injection pipes 31 , which are evenly distributed in a ring shape on one side of the C-shaped box 30 .

[0068] In this embodiment, by providing the air jet tubes 31 , multiple air jet tubes 31 can be arranged in a ring shape. When the compressed gas is ejected from the air jet tubes 31 , it will stick to the surface of the brush roller 18 , thereby improving the dust cleaning effect.

[0069] Working Principle: When the remote-controlled vehicle 1 drives the gas monitor 2 to move, air enters the protective box 7 through the air inlet 8. The air then senses whether there is a chemical gas leak through the sensor probe 3. At the same time, the dust net 9 isolates the dust, thereby preventing dust from being adsorbed on the surface of the sensor probe 3 and improving the monitoring accuracy.

[0070] When dust accumulates on the dust-proof net 9, by starting the motor 11, the motor 11 will drive the worm 12 to rotate. Since the worm 12 is meshed with the worm wheel 13, the worm wheel 13 will rotate synchronously with the worm 12. When the worm wheel 13 rotates, it will drive the screw 14 to rotate around the bearing. The screw 14 will drive the transmission block 15 to move back and forth left and right. The L-shaped block 16, the support block 17 and the brush roller 18 will move back and forth synchronously with the transmission block 15. When the brush roller 18 moves back and forth, it will remove the dust on the surface of the dust-proof net 9 to prevent dust from accumulating on the surface of the dust-proof net 9, thereby improving the accuracy of monitoring.

[0071] When the transmission block 15 drives the L-shaped block 16 to move back and forth, the extrusion rod 23 in the vibration mechanism will also move back and forth synchronously. When the arc portion of the extrusion rod 23 contacts the slope portion of the extrusion block 24, the extrusion rod 23 is affected by the extrusion, which will drive the rebound block 20, the sliding block 21 and the knocking rod 22 to move toward the side close to the return spring 19, and compress the return spring 19 at the same time. When the extrusion rod 23 moves to no longer contact the extrusion block 24, the elastic force generated by the return spring 19 will push the rebound block 20 to reset suddenly, and the sliding block 21 and the knocking rod 22 will also move synchronously, so that one end of the sliding rod knocks on the vibration block 25, generating vibration. After that, the vibration force will be transmitted to the brush roller 18 through the support block 17, shaking off the dust adhering to the surface of the brush roller 18, preventing the dust from adhering to the surface of the dustproof net 9 again, thereby improving the monitoring accuracy;

[0072] When the rebound block 20 moves toward the side close to the return spring 19, it drives the push rod 33, the push block 34 and the piston plate 37 to move. The piston plate 37 will compress the gas in the gas collecting cylinder 27. When the air pressure in the gas collecting cylinder 27 is greater than the limit of the one-way pressure valve 36, the gas will be ejected from the exhaust pipe 29, and then pass through the C-shaped box 30 and then be evenly sprayed on the surface of the brush roller 18 by multiple jet pipes 31. When the elastic force generated by the return spring 19 pushes the rebound block 20 to move to the side away from the return spring 19, the push rod 33, the push block 34 and the piston plate 37 will move synchronously with the rebound block 20. At this time, there is negative pressure in the gas collecting cylinder 27, and the gas will enter the interior of the gas collecting cylinder 27 from the air inlet pipe 28, and spray the gas to the surface of the brush roller 18 intermittently in a cycle, effectively blowing off the dust and preventing the dust from adhering to the dustproof net 9 again, thereby improving the monitoring accuracy.
