Description

Calibrating device for combustible gas detection alarm Technical Field The utility model relates to the technical field of calibrating devices, in particular to a combustible gas detection alarm calibrating device. Background The combustible gas is a substance which can be ignited and is in a gas state at normal temperature and normal pressure, in order to avoid fire caused by the leakage of the combustible gas, a combustible gas detection alarm is required to be installed at a position where the combustible gas is conveyed or used, the combustible gas alarm is also called a gas leakage detection alarm instrument, when the combustible gas in an industrial environment and a daily living environment (such as a kitchen using natural gas) leaks, the combustible gas alarm detects that the concentration of the combustible gas reaches an alarm value set by the alarm, the combustible gas alarm can send out an audible and visual alarm signal so as to remind people to evacuate, forcibly exhaust, shut down equipment and other safety measures, and verification is required when the combustible gas alarm is used and produced. When the existing combustible gas detection alarm is used for on-site detection, workers are required to carry standard gas and gas is introduced into an alarm probe, and the reaction condition of the alarm is observed. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a device for calibrating a combustible gas detection alarm, which overcomes the defects of the prior art and effectively solves the problems that the alarm cannot normally react and the detection result is inaccurate because the use environment of the alarm is complex in the prior art. In order to achieve the above purpose, the present utility model adopts the following technical scheme: the utility model provides a combustible gas detection alarm calibrating installation, includes the gas shell, the one end is pegged graft in the gas shell has the gas pitcher, and the other end spiro union of gas shell has the handle screw rod, the one end of handle screw rod rotates and is connected with the bottom block, the one end of gas shell is pegged graft and is connected with coupling hose, and coupling hose's one end is pegged graft and is had positioning mechanism, positioning mechanism includes the drain pan, peg graft and be fixed in the fixed pipe of drain pan bottom, welded fastening in the fixed block of drain pan both sides outer wall, tie in the rope on fixed block top, set up in the top shell of drain pan top, install respectively and be fixed in the guide block at top both ends, welded fastening respectively in the installation piece of top shell top both sides, rotate the rolling wheel of being connected between two installation pieces, cup joint and be fixed in the spacer ring of rolling wheel outer wall. The alarm to be detected is positioned between the top shell and the bottom shell through the suction disc, the air tank is inserted into the air shell, the handle screw rod is rotated to enable the bottom shell to approach one end of the bottom of the air tank in the air shell, when the bottom of the air tank is pushed, the air nozzle of the air tank and one end in the air shell are mutually extruded, gas in the air tank enters the connecting hose through one end in the air shell, the gas enters between the bottom shell and the top shell through the connecting hose and the fixing tube, the function of the alarm is detected through close distance, the winding wheel is driven by the servo motor to rotate, the winding wheel rotates two ropes to enable the bottom shell to be gradually far away from the top shell, the position of ventilation is gradually far away from the alarm along with the bottom shell, and therefore the largest detection range of the alarm can be judged.
