Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, and more specifically, to a collection device for gas detection. Background Art

[0002] The safety of cargo holds is crucial in the operation of specialized vessels such as chemical tankers, oil tankers, LNG carriers, and LPG carriers. The cargoes carried by these vessels are often flammable, explosive, toxic, or corrosive, and even slight changes in their storage conditions can pose serious safety hazards. This device continuously monitors the internal gas composition in real time in the cargo hold area, ensuring that any generation or leakage of harmful gases is quickly detected. This not only prevents catastrophic accidents such as fires and explosions caused by excessive gas concentrations, but also effectively protects crew members from toxic gases and safeguards their lives. The densely packed machinery and equipment in the engine room, during continuous operation, may generate various exhaust gases and potentially harmful gas leaks. For the crew's daily living and working areas, maintaining fresh and safe air quality is equally important. The collection device for gas detection can monitor and control the air quality in the living area in real time, ensuring that the concentration of harmful gases always remains within a safe range. In traditional devices, when the device collects harmful gases, the harmful gases are stored inside the device. When the gas is gradually collected by the device to a certain level, if it is not handled in time, there will be safety hazards, leading to gas leakage and even the risk of explosion. Therefore, it needs to be improved and optimized. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0021] like Figures 1 to 6As shown, the utility model provides a gas detection collection device, including a shell 1, a sliding plate 2 is slidably installed inside the shell 1, two rectangular columns 9 are fixedly installed on the top of the sliding plate 2, and tooth grooves 12 are respectively provided on the right sides of the two rectangular columns 9. A mounting groove 5 is provided on the right side of the shell 1, and a rotating rod 6 is rotatably installed on the inner wall of the mounting groove 5. A door panel 7 and a gear 8 are fixedly sleeved on the outer wall of the rotating rod 6. There are two gears 8, and two fixed blocks 18 are fixedly installed on the inner wall of the mounting groove 5. A round rod 19 is rotatably installed on the side of the two fixed blocks 18 close to each other. Two gears 20 are fixedly sleeved on the outer wall of the round rod 19, and the two gears 20 are respectively engaged with the corresponding tooth grooves 12 and gear 8.

[0022] When moving upward through the rectangular column 9, the linear motion is efficiently converted into the rotational motion of the gear 2 20 through the meshing mechanism of the tooth groove 12 and the gear 2 20. The gear 2 20 meshes with the gear 1 8, thereby ensuring that the door panel 7 can rotate quickly and stably in response to changes in the internal air pressure. Compared with the traditional device, the precise matching of the tooth groove 12 and the gear 1 8 makes it possible to precisely control the rotation angle and speed of the door panel 7. When too much gas is collected inside the shell 1 and the air pressure rises to a certain level, the door panel 7 can automatically rotate to open the gap and release the internal pressure in time, effectively preventing the risk of explosion or damage caused by excessive air pressure, and improving the safety performance of the system.

[0023] First, the staff ensures that the shell 1 of the gas detection collection device is intact and all components are installed in place. Check whether the gas collector 13 is in normal working condition, whether the hollow tube 14 and the collection head 15 are firmly installed, and whether the filter 3 is clean and unblocked. According to the type of gas to be collected, select a suitable collection head 15 and install it on the hollow tube 14. Use the sliding connection of the L-shaped groove 16 and the cylindrical protrusion 17 to ensure stability. Start the gas collector 13 as an existing device and start collecting gas in the environment around the shell 1 through the hollow tube 14 and the collection head 15. As the gas is continuously collected, the air pressure inside the shell 1 gradually increases. When the air pressure rises to a certain level and reaches the preset threshold, the sliding plate 2 slowly moves upward, squeezing the spring damping rod assembly 4 at the same time. The sliding plate 2 drives the rectangular column 9 to move upward together. The upward movement of the rectangular column 9 is efficiently converted into the rotational motion of the gear 2 20 through the meshing mechanism of the tooth groove 12 and the gear 2 20. The gear 2 20 meshes with the gear 1 8 to drive the gear 1 8 to rotate. The rotation of the gear 1 8 drives the rotating rod 6 and the door panel 7 fixed thereon to rotate, so that a gap is generated between the outside and the inside of the shell 1. The opening of the gap allows the excessive air pressure inside the shell 1 to be released through the gap, effectively preventing the risk of explosion or damage caused by excessive air pressure. When the gas before release passes through the filter 3, the impurities and particulate matter therein are filtered out, making the released gas harmless. The collected gas samples can be tested by the analysis equipment connected to the gas collector 13 to obtain the required gas composition, concentration and other information. According to the test results, corresponding subsequent treatment measures are taken, such as discharge, storage or further analysis.

[0024] Among them, a gas collector 13 is fixedly installed on the bottom inner wall of the outer shell 1, and a hollow tube 14 is fixedly installed on the left outer wall of the gas collector 13. The hollow tube 14 extends to the outside of the outer shell 1 and is fixedly connected to the outer shell 1. A collecting head 15 is slidably installed on the top of the hollow tube 14. Two L-shaped grooves 16 are provided on the outer wall of the hollow tube 14. The two L-shaped grooves 16 are symmetrically distributed. Two cylindrical protrusions 17 are fixedly installed on the inner wall of the collecting head 15. The two cylindrical protrusions 17 are adapted to the corresponding L-shaped grooves 16 and are slidably connected to the corresponding L-shaped grooves 16.

[0025] The collecting head 15 is slidably mounted on the top of the hollow tube 14 and is slidably connected to the L-shaped groove 16 and the cylindrical protrusion 17, which greatly enhances its flexibility in quick installation, disassembly and replacement. Compared with traditional devices, when the collecting head 15 needs to be replaced to adapt to different gas collection tasks or for regular maintenance, the user can quickly remove the old collecting head and replace it with a new one. The convenient replacement function reduces downtime and improves the availability and flexibility of the equipment. By quickly replacing the collecting head, the user can reduce the contact time with potentially harmful gases, thereby reducing safety risks.

[0026] A filter screen 3 is provided on the top of the sliding plate 2 . The area of ​​the filter screen 3 is smaller than that of the sliding plate 2 and the filter screen 3 is located at the center of the sliding plate 2 .

[0027] The filter 3 is provided to filter out impurities and particulate matter in the gas, thereby preventing the gas from being discharged and polluting the environment.

[0028] The top inner wall of the housing 1 and the top of the sliding plate 2 are elastically connected via four spring damping rod assemblies 4 , and the four spring damping rod assemblies 4 are designed to be distributed diagonally in a rectangular shape.

[0029] By providing the spring-damping rod assembly 4 , the elastic connection of the spring-damping rod assembly 4 provides effective buffering and shock absorption effects for the sliding plate 2 .

[0030] Among them, convex blocks 11 are fixedly installed on the front and back of the sliding plate 2, and sliding grooves 10 are respectively opened on the front inner wall and the back inner wall of the shell 1. The two sliding grooves 10 are adapted to the corresponding rectangular columns 9 and are slidably connected with the corresponding rectangular columns 9.

[0031] The close fit between the convex block 11 and the sliding groove 10 provides precise guiding for the sliding plate 2, ensuring the stability and linearity of the sliding plate 2 during movement and effectively preventing the sliding plate 2 from deflecting or shaking during movement, thereby ensuring the accuracy and reliability of the gas collection process.

[0032] The vertical height of the tooth groove 12 is smaller than the vertical height of the rectangular column 9 .

[0033] By designing the height difference between the tooth groove 12 and the rectangular column 9, a clear limit is set for the rotation of the gear 8, ensuring that the gear 8 will not exceed the predetermined range during the rotation process, thereby achieving precise control of the rotation angle.

[0034] The working principle and use process of this utility model:

[0035] First, the staff ensures that the shell 1 of the gas detection collection device is intact and all components are installed in place. Check whether the gas collector 13 is in normal working condition, whether the hollow tube 14 and the collection head 15 are firmly installed, and whether the filter 3 is clean and unblocked. According to the type of gas to be collected, select a suitable collection head 15 and install it on the hollow tube 14. Use the sliding connection of the L-shaped groove 16 and the cylindrical protrusion 17 to ensure stability. Start the gas collector 13 as an existing device and start collecting gas in the environment around the shell 1 through the hollow tube 14 and the collection head 15. As the gas is continuously collected, the air pressure inside the shell 1 gradually increases. When the air pressure rises to a certain level and reaches the preset threshold, the sliding plate 2 slowly moves upward, squeezing the spring damping rod assembly 4 at the same time. The sliding plate 2 drives the rectangular column 9 to move upward together. The upward movement of the rectangular column 9 is efficiently converted into the rotational motion of the gear 2 20 through the meshing mechanism of the tooth groove 12 and the gear 2 20. The gear 2 20 meshes with the gear 1 8 to drive the gear 1 8 to rotate. The rotation of the gear 1 8 drives the rotating rod 6 and the door panel 7 fixed thereon to rotate, so that a gap is generated between the outside and the inside of the shell 1. The opening of the gap allows the excessive air pressure inside the shell 1 to be released through the gap, effectively preventing the risk of explosion or damage caused by excessive air pressure. When the gas before release passes through the filter 3, the impurities and particulate matter therein are filtered out, making the released gas harmless.
