Description

Technical Field

[0001] The utility model relates to the technical field of chemical production protection, in particular to a chemical production safety protection device. Background Art

[0002] Chemical production refers to the process of chemically processing raw materials to ultimately obtain valuable products. This process includes chemical reactions and several physical operations, of which the chemical reaction and reactor are the core, while the physical process prepares the appropriate conditions for the chemical reaction and separates and purifies the reactants to obtain the final product. Since most of the raw materials used in chemical production are corrosive, flammable, explosive, toxic, or even highly toxic, safety protection is required for on-site workers.

[0003] An existing chemical safety protection device (Announcement No.: CN220928968U) can achieve effective warning and protection of the chemical protection device by setting support columns, protection frame, protection net, infrared detector, warning flashing light, warning display screen and chemical warning sign. However, after the protection frame is fixed at a height on the support column, it is not convenient to increase the protection range on site, which in turn affects the protection effect. In addition, when performing protection work in outdoor sites, it is still easy to topple over, and the stability is not ideal. Summary of the Invention

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. After moving the device to the work site, the staff pushes the card frame to plug into the protrusion, and then uses tools to tighten the expansion bolts to fix the card frames and protrusions on both sides in turn. Then, the protective plate is installed on the support plate, and the screw is manually turned clockwise to rotate the screw upward through the threaded sleeve. Under the action of the rotating shaft, the screw pushes the fixed block to move, and the fixed block drives the extension plate to move up, and at the same time drives the card strip to slide along the card slot, thereby moving the extension plate out from the side of the protective plate to increase the protection range. In addition, with the cooperation of the speaker and the solar panel, the safety warning for the on-site staff can be strengthened.

[0014] 2. When it is necessary to use it in an outdoor venue, the staff can pull the rod upward to drive the connecting ring to move upward, so that the connecting ring and the sleeve ring cooperate to squeeze the spring to deform, and then pull out the limit plate to the outside. After loosening the rod, the spring rebounds to release energy, and then drives the bottom end of the rod to be inserted into the soil. The four groups of rods enhance the stability of the outdoor protective support and improve safety. After use, the rod can be retracted into the inside of the support plate, which is convenient for use in indoor venues and improves the flexibility of use. BRIEF DESCRIPTION OF THE DRAWINGS
