Description

Fireproof sealing device for bottom of electrical cabinet Technical Field The utility model relates to the field of electrical cabinet equipment, in particular to a fireproof sealing device for the bottom of an electrical cabinet. Background The electric cabinet body is used as an indispensable key component in a plurality of fields such as power systems, industrial automation and the like, and the relay, the breaker, the measurement and control protection device and other core electric elements stored in the electric cabinet body are used for controlling the on-off of current, monitoring the state of a power grid and guaranteeing the accurate distribution and transmission of electric energy, so that a safe and stable operation environment is required, and fire and humid environments are two main threat factors for the safe operation of the electric cabinet body. For the problems, when the electric cabinet is installed in the prior art, most of the electric cabinet is coated with a protective material at the bottom for fireproof and moistureproof treatment, the traditional protective coating in the market mainly comprises a two-component castable, inorganic fireproof plaster or fireproof mud, wherein the two-component castable is matched with a template for use, the sealing performance is good, but the modeling difficulty is high, the inorganic fireproof plaster is made of an inorganic material, the environment-friendly advantage is achieved, a stronger and smooth-surface protective layer can be formed when the electric cabinet is used, the model structure is easy to collapse and crack due to the large dead weight in the modeling process, the molding effect and the protective performance are seriously affected, and moreover, the fireproof mud is convenient to construct, but has poor weather resistance and is easy to decline in various performances after long-term use. The fireproof material belongs to a semi-finished product, and when the fireproof material is used, water is required to be added on site and uniformly stirred according to a certain component proportion, and the accuracy is uncontrollable or the characteristics of the fireproof material are possibly affected when the component proportion is regulated in the process, or the stirring is uneven.
