Abstract

The invention discloses a closed space safety alarm apparatus, and relates to the technical field of gas detection, the closed space safety alarm apparatus comprises a base and an alarm apparatus assembly, the alarm apparatus assembly comprises an alarm apparatus main body, and the bottom of the alarm apparatus main body is provided with a gas inlet; a telescopic rod is driven to be matched with a fixing rod to be fixed to a mounting object under the elastic force effect of a compression spring, the fixing rod is designed to be in an arc shape, the fixing rod can be better attached to the mounting object, and the fixing effect of the fixing rod on the fixing rod is improved; and the fixing mode mainly aims at a mounting object with a round surface or a cylindrical surface, is convenient to use and facilitates improvement of mounting and fixing efficiency, the alarm apparatus main body can be mounted on the mounting object by matching the connecting plate with the bolts, and the fixing mode mainly aims at a mounting object with a flat surface or a wall body. An oxygen detection module, a hydrogen sulfide detection module, a combustible gas detection module and a carbon monoxide detection module are integrated on the same alarm apparatus main body, so that four gases can be detected at the same time.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a safety alarm device for a confined space. Background technique [0002] Industrial production, smelting and forging, electric power, coal mining, tunnel engineering, environmental monitoring, sewage treatment, biopharmaceuticals, household environmental protection, animal husbandry, greenhouse cultivation, school laboratories, scientific research centers and other industries have strict requirements on gases, such as in agricultural production The field needs sufficient oxygen, and the waste gas produced in the industrial chemical field needs to meet the standard before it can be discharged. If it does not meet the standard, it will pollute the environment, etc., and there are often safety accidents in the confined space, mainly pipelines, warehouses, workshops, etc. Enterprises are usually concerned about this aspect. The gas will be detected by installing a gas detectio...
