Description

Technical Field

[0001] This invention relates to the field of gas detection equipment technology, and in particular to a propane tank gas volatilization leakage detection device. Background Technology

[0002] Propane is a flammable and explosive gas widely used in industrial production and domestic gas supply. Safety precautions during its storage and use are crucial. Valves and interfaces of propane tanks are high-risk areas for gas leaks. Once a leak occurs, the propane gas mixes with air and reaches its explosive limit, easily causing fires, explosions, and other safety accidents, seriously threatening lives and property.

[0003] Currently, most methods for propane tank leak detection involve installing fixed concentration detection probes directly in the tank area environment. However, this method suffers from problems such as delayed detection response, susceptibility to interference from ambient airflow, and inability to accurately contain and collect the leak source. Furthermore, it lacks mechanisms for collecting and treating leaked gases, making it difficult to meet the actual needs of leak detection in critical components such as propane tank valves and interfaces. Therefore, there is a need to design a propane tank leak detection device that offers accurate detection, efficient collection, and strong adaptability. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a propane tank gas volatilization leakage detection device, comprising a leakage prevention component, an inspection component, and an alarm component; The leak-proof component is installed on the outside of the valves and interfaces of the propane tank to initially contain and collect leaked gas. The detection component is connected to the leak prevention component and is used to detect the propane gas concentration in the leak prevention component in real time. The alarm component is electrically connected to the detection component and is used to issue an alarm signal when the propane concentration exceeds the standard.

[0005] Preferably, the leak-proof assembly includes a fixing component and a flexible sealing cover. There are two fixing components, which are respectively fixed to the top and bottom opening edges of the flexible sealing cover. The fixing components are bonded to the flexible sealing cover to ensure sealing performance at the openings. A rigid support frame is fixed to the outer wall of the flexible sealing cover to maintain its shape and prevent collapse that could affect gas collection. Two sets of telescopic support rods are symmetrically arranged at the bottom of the rigid support frame. The bottom ends of the telescopic support rods are detachably connected to a fixed seat at the top of the propane tank, and shock-absorbing springs are sleeved on the outer sides of the telescopic support rods.

[0006] Preferably, the bottom end of the telescopic support rod is provided with a vacuum suction cup, which enables quick disassembly and connection with the propane tank fixing seat through vacuum adsorption.

[0007] Preferably, the detection component includes a gas sensor module and a signal processor. The detection probe of the gas sensor module extends through the flexible sealing cover into the interior for real-time acquisition of propane concentration signals. The signal processor is electrically connected to the gas sensor module, and the alarm component is electrically connected to the signal processor.

[0008] Preferably, the bottom of the flexible sealing cover is connected to a collection pipe, an explosion-proof air pump is connected in series on the collection pipe, and the end of the collection pipe is connected to a gas collection tank.

[0009] Preferably, the gas collection tank is equipped with a pressure monitoring gauge and a pressure relief valve on its outer side.

[0010] Preferably, it also includes a data transmission component, which includes a wireless communication module and a cloud server. The wireless communication module is electrically connected to the signal processor and is used to upload propane concentration data to the cloud server in real time. The cloud server supports remote terminal access and query.

[0011] Preferably, it also includes a power supply component, which includes a battery and a charging management module. The battery and the charging management module are integrated into a protective box set on the telescopic support rod. The charging management module is electrically connected to the battery to provide a stable power supply to each electrical component of the device.

[0012] Preferably, the collection pipe is made of stainless steel, the inner wall of the collection pipe is coated with polytetrafluoroethylene for corrosion protection, and the connection between the collection pipe and the flexible sealing cover and the gas collection tank is provided with sealing gaskets, the sealing gaskets being made of fluororubber.

[0013] Preferably, the fastener includes an elastic strip, one end of which is provided with a plurality of adjustment holes, and the other end of which is provided with a through hole. The beginning and end of the elastic strip pass through the through hole to form a closed loop. After two adjustment holes overlap, they are connected by a fastener passing through the two adjustment holes.

[0014] Beneficial effects: Compared with existing technologies, this invention achieves full enclosure of valves or interfaces through the cooperation of a flexible sealing cover and fixing components. The inner activated carbon fiber adsorption layer can adsorb and enrich leaked gas, and the fluororubber sealing gasket at the connection of the collection pipe further blocks the leakage path. The multiple sealing design ensures that leaked gas does not diffuse, improving detection accuracy. The gas sensor probe extends directly into the inside of the sealing cover, and combined with the adsorption and enrichment effect of activated carbon fiber, it can quickly capture changes in propane concentration. The signal processor processes the data in real time, avoiding detection lag caused by environmental interference. The telescopic support rod is adjustable in length to adapt to the installation requirements of propane tanks of different specifications. The vacuum suction cup enables quick and detachable connection, and the shock-absorbing spring improves the device's vibration resistance and ensures installation stability. At the same time, leaked gas can be collected into a gas collection tank by an explosion-proof vacuum pump, and the pressure monitoring gauge and pressure relief valve ensure safe storage.

Detailed Implementation

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] Example Please refer to the accompanying drawings in the specification. In this embodiment of the invention, a propane tank gas volatilization leakage detection device includes a leakage prevention component, an inspection component, and an alarm component. The leak prevention component is installed on the outside of the valves and interfaces of propane tank 1 to initially contain and collect leaked gas. The detection component is connected to the leak prevention component and is used to detect the propane gas concentration in the leak prevention component in real time. The alarm component is electrically connected to the detection component and is used to issue an alarm signal when the propane concentration exceeds the standard.

[0022] The leak-proof assembly includes a fixing member 2 and a flexible sealing cover 3. There are two fixing members 2, which are respectively fixed to the top opening edge and the bottom opening edge of the flexible sealing cover 3, and the fixing members 2 are fixedly connected to the flexible sealing cover 3 by adhesive bonding. A rigid support frame 4 is fixedly provided on the outer wall of the flexible sealing cover 3. Two sets of telescopic support rods 5 are symmetrically provided at the bottom of the rigid support frame 4. The bottom end of the telescopic support rods 5 is detachably connected to the fixed seat at the top of the propane tank 1, and a shock-absorbing spring 6 is sleeved on the outside of the telescopic support rods 5.

[0023] The bottom end of the telescopic support rod 5 is equipped with a vacuum suction cup 7. The vacuum suction cup 7 is made of nitrile rubber and has an adsorption force of not less than 100N, ensuring a stable connection with the top fixing seat of the propane tank 1.

[0024] The detection component includes a gas sensor module 8 and a signal processor 9. The detection probe of the gas sensor module 8 extends through the flexible sealing cover 3 into the interior for real-time acquisition of propane concentration signals. The signal processor 9 is electrically connected to the gas sensor module 8, and the alarm component is electrically connected to the signal processor 9.

[0025] The alarm component uses an audible and visual alarm 10 with an alarm volume ≥85dB and a flashing red alarm light. It is connected to the signal processor 9 via a GPIO interface. When the propane concentration exceeds 10% of the explosion limit (i.e., 1.0% VOL), the signal processor 9 triggers the alarm component to work. The bottom of the flexible sealing cover 3 is connected to a collection pipe 11, and an explosion-proof air pump 12 is connected in series on the collection pipe 11. The end of the collection pipe 11 is connected to a gas collection tank 13.

[0026] The gas collection tank 13 is equipped with a pressure monitoring gauge 14 and a pressure relief valve 15 on its outer side.

[0027] It also includes a data transmission component, which includes a wireless communication module 16 and a cloud server 17. The wireless communication module 16 is electrically connected to the signal processor 9 and is used to upload propane concentration data to the cloud server in real time. The cloud server 17 supports remote terminal access and query.

[0028] It also includes a power supply component, which includes a storage battery 18 and a charging management module 19. The storage battery 18 and the charging management module 19 are integrated in a protective box 20 set on the telescopic support rod 5. The charging management module 19 is connected to the storage battery 18 to provide a stable power supply to each electrical component of the device.

[0029] The collection pipe 11 is made of stainless steel, and the inner wall of the collection pipe 11 is coated with polytetrafluoroethylene for corrosion protection. The connection between the collection pipe 11 and the flexible sealing cover 3 and the gas collection tank 13 is provided with sealing gaskets, and the sealing gaskets are made of fluororubber.

[0030] The fastener 2 includes an elastic strip 201. One end of the elastic strip 201 is provided with a plurality of adjustment holes 202 evenly distributed. The other end of the elastic strip 202 is provided with a through hole 203. The beginning and end of the elastic strip 201 pass through the through hole to form a closed loop. After the two adjustment holes 202 overlap, they are connected by a fastener 204 passing through the two adjustment holes 202.

[0031] Working principle: Adjust the length of the telescopic support rod 5 according to the height of the fixed base on the top of the propane tank 1, and fix the device to the fixed base using the vacuum suction cup 7; then, according to the valve and interface size of the propane tank 1, fit the flexible sealing cover over the valve and interface, adjust the adjustment hole 202 of the fixing part 2, and use the fixing buckle 204 to tightly cover the outside of the valve and interface. After the device is powered on, the gas sensor module 8 collects the propane concentration signal in the flexible sealing cover 3 in real time and transmits it to the signal processor 9 for processing. When the concentration reaches 1.0%VOL, the signal processor 9 triggers the audible and visual alarm 10 to work; at the same time, the explosion-proof gas pump 12 starts to pump the leaked gas in the flexible sealing cover 3 to the gas collection tank 13, the pressure monitoring gauge 14 monitors the pressure in the tank in real time, and releases pressure through the pressure relief valve 15 when overpressure occurs.

[0032] The wireless communication module 16 uploads the detection data to the cloud server 17, and staff can view the data through a remote terminal to achieve real-time monitoring.

[0033] In the above process, this invention achieves full enclosure of the valve or interface through the cooperation of a flexible sealing cover and a fixing component. The inner activated carbon fiber adsorption layer can adsorb and enrich the leaked gas, and the fluororubber sealing gasket at the connection of the collection pipe further blocks the leakage path. The multiple sealing design ensures that the leaked gas does not diffuse, improving detection accuracy. The gas sensor probe extends directly into the inside of the sealing cover. Combined with the adsorption and enrichment effect of the activated carbon fiber, it can quickly capture changes in propane concentration. The signal processor processes the data in real time, avoiding detection lag caused by environmental interference. The telescopic support rod is adjustable in length to adapt to the installation requirements of propane tanks of different specifications. The vacuum suction cup enables quick and detachable connection, and the shock-absorbing spring improves the device's vibration resistance and ensures installation stability. At the same time, the leaked gas can be collected into the gas collection tank by an explosion-proof gas pump, and the pressure monitoring gauge and pressure relief valve ensure safe storage.
