Description

Technical Field

[0001] This utility model relates to the technical field of liquefied gas detection, specifically to an automatic liquefied gas leak alarm. Background Technology

[0002] Liquefied petroleum gas (LPG) is mainly composed of hydrocarbons, with propane, butane, and other alkanes as its main components. Due to its high calorific value and the presence of hydrocarbons with low ignition points, LPG is highly explosive and flammable. In the event of a leak, it can easily lead to safety accidents, posing a significant threat to personal and property safety.

[0003] To prevent serious adverse consequences from liquefied petroleum gas (LPG) leaks, LPG alarms are typically installed in environments where LPG is stored, transported, and used to monitor its concentration. Existing LPG alarms monitor ambient LPG concentration by using an air inlet at the bottom of the alarm to bring the gas into contact with the sensor, thus achieving detection. However, this method has the following problems:

[0004] Detection is performed using naturally flowing air, which results in low detection efficiency and an inability to perform rapid, real-time detection. Furthermore, the overall device does not allow for easy disassembly and assembly, and it is difficult to quickly replace and perform functional tests on internal detection components.

[0029] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0030] See Figure 1-3As shown, an automatic liquefied gas leak alarm includes a guide tube 1, a functional base 7, and a flow diversion assembly 9. One end of the guide tube 1 is fixedly connected to a first flow guide cover 2, and a flow guide window 3 is opened on the surface of one end of the guide tube 1. The top of the guide tube 1 is fixedly connected to a track seat 4 and a fixing seat 5, and the bottom of the guide tube 1 is fixedly connected to an outer fixing clamp 6. The inner and outer ends of the flow diversion assembly 9 are respectively fixedly connected to a first fixing frame 8 and a second fixing frame 10. The flow diversion assembly 9 includes a flow diversion tube 12 embedded in one end of the guide tube 1, a second flow guide cover 11 at both ends, and a sealing cover 14. A flow diversion fan 13 is fixedly connected inside the flow diversion tube 12, and a detection mechanism 15 is fixedly connected inside the functional base 7. The detection mechanism 15 is also embedded inside the guide tube 1.

[0031] In this embodiment of the utility model, the flow guide tube 1 is arranged horizontally, with one end facing the first flow guide hood 2 tapering towards the other end in an arc shape, and the lower part of the flow guide tube 1 has an arc-shaped transition. The first flow guide hood 2 is an outwardly flared conical hood that is sealed to one end of the flow guide tube 1. The flow guide window 3 is arranged in an arc shape around one end of the surface of the flow guide tube 1, and its surface has honeycomb perforations. The first flow guide hood 2 and the flow guide window 3 are located at the same end of the flow guide tube 1. The first flow guide hood 2 and the flow guide window 3 facilitate the entry of external airflow into the flow guide tube 1, and the flow guide tube 1 achieves the effect of quickly introducing external airflow and collecting and transporting it.

[0032] When using this device, the external airflow passes through the guide assembly 9 and quickly enters the guide tube 1 from the first guide shroud 2. The guide window 3 can assist the first guide shroud 2 in ensuring the external airflow. After entering the guide tube 1, the airflow is concentrated and flows along the guide tube 1, which is more conducive to the detection mechanism 15 to accurately detect the liquefied gas content inside the air.

[0033] The external fixing plate 6 is horizontally positioned and fixedly connected to the bottom longitudinal sides of the guide tube 1. The external fixing plate 6 is also located on both sides of the functional base 7, which is fan-shaped and fits against the bottom of the guide tube 1. Curved sealing rings are provided at the contact points between the functional base 7 and the bottom of the guide tube 1. The detection mechanism 15 is vertically positioned, penetrating the functional base 7 and embedding itself into the guide tube 1. Hemispherical sealing sleeves are provided at the embedding points of the detection mechanism 15 and the guide tube 1. The external fixing plate 6 achieves the effect of connecting and fixing the guide tube 1 and the functional base 7. The modular design of the functional base 7 with the guide tube 1 facilitates quick assembly and disassembly of the internal detection mechanism 15. The curved sealing ring between the functional base 7 and the guide tube 1, together with the sealing sleeve between the detection mechanism 15 and the guide tube 1, effectively ensures the sealing of the detection environment and guarantees the accuracy of the detection.

[0034] The flow guide tube 12 is horizontally positioned and is embedded in the flow guide tube 1 along with the sealing cover 14. The sealing cover 14 and the flow guide tube 1 are sealed together. The second flow guide cover 11 is conical and outwardly flared, and is fitted together with the second fixing frame 10. Both the first fixing frame 8 and the second fixing frame 10 are L-shaped. The first fixing frame 8 is fitted together with the flow guide tube 12, while the second fixing frame 10 is located outside the flow guide tube 1, and its surface has a sleeve opening corresponding to the second flow guide cover 11. The outer end of the flow guide fan 13 is equipped with a drive motor. The flow guide tube 12 and the built-in flow guide fan 13 achieve the effect of quickly introducing external airflow into the flow guide tube 1. The sealing cover 14 ensures the sealing effect of the fit between the flow guide tube 12 and the flow guide tube 1. The outwardly flared second flow guide cover 11 achieves the effect of quickly expelling the airflow inside the flow guide tube 1. The first fixing frame 8 and the second fixing frame 10 achieve the effect of connecting and fixing the flow guide tube 12 and the flow guide tube 1.

[0035] When the diversion tube 12 and the sealing cover 14 are embedded in the diversion tube 1, the first fixing frame 8 is first fixedly connected to one end of the diversion tube 1. Then, the diversion tube 12 is inserted into the diversion tube 1 through the first fixing frame 8. Then, the second fixing frame 10 and the second diversion cover 11 are fitted together, and the bottom of the second fixing frame 10 is connected to the outside of the first fixing frame 8. This completes the overall installation of the diversion assembly 9. During installation, the fixing seat 5 is connected to the external plane, and then it is fitted with the track seat 4 to complete the installation of the device. During use, the diversion fan 13 can actively introduce external airflow into the diversion tube 1 for detection and processing, thereby improving detection efficiency.

[0036] The detection mechanism 15 of this device is existing publicly available technology and will not be described in detail here.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
