Description

Technical Field

[0001] This utility model relates to the field of gas cylinder transportation and use technology, and in particular to a standard gas cylinder depressurization transportation device. Background Technology

[0002] Existing gas cylinders are secured with steel frames during transportation, which makes them unstable due to roadside bumps. Gas leaks during transport pose significant safety hazards and diminish the cylinder's usability. Furthermore, during use, it's difficult to flexibly switch between different gases to meet varying monitoring needs, and the gas handling process is cumbersome with complex connection requirements. Utility Model Content

[0003] The purpose of this invention is to provide a standard gas cylinder depressurization and transportation device to solve the problems encountered in the background art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A standard gas cylinder pressure-reducing transport device includes a storage box and a gas cylinder. The storage box is a box structure that can be opened from both the front and back. The gas cylinder is installed in the storage box by a fixing mold. An electric valve, a pressure-reducing valve, and a pipe joint are installed at the gas output end of the gas cylinder. An alarm device for gas status detection is installed in the storage box, and rollers are installed at the bottom of the storage box.

[0006] In the above solution, a pull rod is installed on the top of the storage box, an exhaust port communicating with the interior is opened on one side of the bottom of the storage box, and a plug is provided on the other side of the bottom of the storage box. The plug is connected to an alarm device, an electric valve, and a pressure reducing valve via wiring. As a preferred solution, the fixing mold is made of honeycomb cardboard, and the guide sleeve of the pull rod is inserted into the middle of the fixing mold and connected to the bottom surface of the storage box.

[0007] In the above scheme, an alarm system is installed inside the storage box. The alarm system includes a common exhaust pipe, a pressure detector, and an electric switch. The pressure detector is connected to the alarm device, a plug, an electric valve, the electric switch, and the common exhaust pipe. The electric valve is connected to the pressure reducing valve and then to the common exhaust pipe. As a preferred embodiment, the gas cylinder is connected to the electric valve via a manual switch, and the pressure reducing valve is connected to the common exhaust pipe via a three-way valve.

[0008] In the above scheme, the alarm device includes an alarm, a gas concentration detector, and a status meter. The pressure detector is connected to the status meter and the alarm via a line, the gas concentration detector is connected to the status meter, and the gas concentration detector is connected to the electric valve.

[0009] In the above scheme, a safety valve is installed on the pipeline connecting the pressure detector and the common exhaust pipe, and the electric switch is connected to the exhaust port via a PFA connector. As a preferred embodiment, the input end of the PFA connector is also connected to a one-way valve, which is connected to the internal space environment inside the storage tank.

[0010] Compared with existing technologies, the advantages of this invention are as follows: the gas cylinder is installed in the storage box using a fixing mold. The fixing mold has a concave mold corresponding to the gas cylinder, which can limit multiple sides of the gas cylinder, thereby preventing the gas cylinder from shifting during transportation and facilitating higher transport. The storage box can stably hold multiple 1L standard gas cylinders, ensuring that the gas cylinders will not shake or tip over during movement. Through a reasonable internal layout and labeling, the types of gas in different standard gas cylinders can be clearly distinguished, making it easy for operators to quickly and accurately retrieve the required gas.

[0011] This device is equipped with a pressure reducing valve and pipe fittings. When gas is needed, simply connect the corresponding pipe to the fitting and adjust the pressure reducing valve to control the gas flow. This allows for convenient and quick use of the gas cylinder, facilitating gas access, operation, and testing. The device also includes a gas leak detection alarm. When powered on, it monitors the gas concentration inside the device. In the event of a gas leak, the alarm will immediately emit an audible and visual alarm signal, alerting personnel to take appropriate measures. Attached Figure Description

[0018] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 As shown, a standard gas cylinder depressurization and transportation device includes a storage box 1 and gas cylinders 2. The storage box 1 is a box structure that can be opened from both the front and back. Each storage box 1 holds four gas cylinders 2, two in the front and two in the back. The storage box 1 can be opened by opening either the front or rear cover. The gas cylinders 2 are installed in the storage box 1 by a fixing mold 16. The fixing mold 16 has a concave mold corresponding to the gas cylinder 2, which can limit multiple sides of the gas cylinder 2, thereby preventing the gas cylinders 2 from shifting during transportation and facilitating higher transportation. To accommodate the transportation of gas cylinders 2 of different specifications, standard gas cylinders are used here, and the fixing mold 16 is also a concave mold consistent with standard gas cylinders.

[0020] Gas cylinder 2 is equipped with an electric valve 21, a pressure reducing valve 22, and a pipe connector at its gas output end. The electric valve 21, pressure reducing valve 22, and pipe connector also have corresponding concave molds on the fixed mold 16 for limiting their movement and protecting the integrity of the connected components. When gas 2 is needed, simply connect the corresponding pipe to the pipe connector and adjust the pressure reducing valve 22 to control the gas flow. Different types of gases can be flexibly placed according to the calibration and check requirements of the cleanroom's AMC monitoring system. Through a reasonable internal layout and labeling, the types of gases in different standard gas cylinders can be clearly distinguished, facilitating operators to quickly and accurately obtain the required gas.

[0021] The storage box 1 is equipped with wheels 11 at the bottom to assist in transportation and save effort. As a preferred option, a pull rod 12 is installed on the top of the storage box 1. During manual transportation, the pull rod 12, in conjunction with the wheels 11, facilitates transportation. The fixing mold 16 is made of honeycomb cardboard with many holes to connect the environment inside the storage box 1. The guide sleeve of the pull rod 12 is inserted into the middle of the fixing mold 16 and connected to the bottom surface of the storage box 1. The upper part of the guide sleeve of the pull rod 12 is also fixed to the top of the guide sleeve of the pull rod 12. It is vertically fixed inside the storage box 1. The pull rod 12 and the guide sleeve are telescopic, which is consistent with the current method of using luggage pull rods, and its structure is also similar.

[0022] A vent 14 is provided on one side of the bottom of storage tank 1, connecting to the external environment to prevent safety accidents caused by gas leakage in the sealed space. A plug 15 is located on the other side of the bottom of storage tank 1. Plug 15 is connected to alarm device 13, electric valve 21, and pressure reducing valve 22 via wiring. An external power supply is also connected via plug 15 for monitoring during the storage of gas cylinder 2. For further monitoring of the gas inside storage tank 1, a backup power supply can be installed inside storage tank 1, separately connected to alarm device 13, to provide monitoring in case of power outages or during transportation.

[0023] Storage tank 1 is equipped with an alarm device 13 for gas state detection, which will promptly issue an alarm in case of any abnormality. Based on this alarm device 13, please refer to [link / reference needed]. Figure 2 An alarm system is installed inside storage tank 1. The alarm system includes a common exhaust pipe, a pressure detector 25, and an electric switch 26. The common exhaust pipe is... Figure 2 The "common exhaust" connector in the middle, the pressure detector 25 is connected to the alarm device 13, plug 15, electric valve 21, electric switch 26 and common exhaust pipe respectively. The electric valve 21 is connected to the pressure reducing valve 22 and then connected to the common exhaust pipe.

[0024] The alarm device 13 includes an alarm, a gas concentration detector 131, and a status indicator 132. A pressure detector 25 is connected to the status indicator 132 and the alarm via wiring. The gas concentration detector 131 is connected to the status indicator 132 and the electric valve 21. When the gas concentration exceeds a set threshold, the alarm sounds. The alarm can be an audible and visual alarm, the gas concentration detector 131 can be a gas concentration sensor, and the pressure detector 25 can be a pressure sensor.

[0025] As a preferred embodiment, a safety valve 28 is installed on the pipeline connecting the pressure detector 25 and the common exhaust pipe. The other side of the safety valve 28 is connected to the output terminal of the electric switch 26. The electric switch 26 can also be a solenoid valve 21. The electric switch 26 is connected to the exhaust port 14 via a PFA connector 27. The input terminal of the PFA connector 27 is also connected to a one-way valve 29. The one-way valve 29 is connected to the internal space environment inside the storage tank 1 to assist in exhaust, drawing gas out of the tank and releasing it outside.

[0026] Gas cylinder 2 is connected to electric valve 21 via manual switch 23. Pressure reducing valve 22 is connected to a common exhaust pipe via three-way valve 24. PFA tubing is connected to three-way valve 24 for use with external monitoring instruments, such as gas detectors, to analyze and detect leaks in gas cylinder 2 within the enclosure and verify the accuracy of alarm device 13. Both three-way valve 24 and PFA connector 27 are made of fluoroplastic, which can withstand corrosive media such as strong acids and alkalis, and reacts almost entirely with corrosive gases, ensuring that the gas purity remains uncontaminated during gas transportation.

[0027] When using this alarm system, the electric switch 26 is normally closed, while the electric valve 21 connecting the four gas cylinders 2 is normally open. When the pressure detector 25 detects excessive pressure, it drives the electric switch 26 before the exhaust port 14 to open and release the high pressure. At the same time, it drives the electric valve 21 between the pressure reducing valve 22 and the gas cylinder switch to close, at which point the status indicator 131 flashes orange. When the gas concentration detector 132 detects a gas leak inside the device, it drives the electric valve 21 between the pressure reducing valve 22 and the gas cylinder switch to close, at which point the status indicator 131 flashes red. Therefore, under normal conditions, the status indicator 131 flashes green; when a leak is detected, it flashes red; and when excessive pressure is detected, it flashes orange.
