[0029] How this utility works:

[0030] Refer to the instruction manual Figure 1-Figure 4First, when the leakage alarm device 6 senses the gas leakage in the cylinder, the top blower 2 will automatically work to discharge the gas to the outside through the exhaust pipe. The leakage alarm device 6 is divided into two parts: a host and a probe. The probe part is installed in the cabinet 1 to detect the concentration of flammable, explosive, toxic, corrosive and oxygen gases in the cabinet 1. The host of the leakage alarm device 6 is installed on the outer wall of the cabinet 1 or in the corridor or security room and other locations where it can be found. The temperature and humidity monitor 3 is divided into two parts: a host and a probe. The probe part is installed inside the cabinet 1 to detect the temperature and humidity inside the cabinet 1. The upper and lower limit alarms can be set. When the temperature and humidity exceed or fall below the set value, an alarm is triggered in time to notify relevant personnel to handle it as soon as possible.

[0031] The bottom of the cylinder is placed into the fixing hole 10, and the filling body 11 wraps the cylinder. The filling body 11 can be sand or other materials. Then the sliding plate 1203 is rotated, and the sliding plate 1203 extends from the inside of the connecting groove 1202 and releases the elasticity of the reset spring 1204, so that the reset spring 1204 pushes the push plate 1205 to fit the outer wall of the cylinder to fix the cylinder.
