[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Reference Figure 1-Figure 3 A safety protection device for chemical equipment maintenance includes a protective helmet 1, which is made of anti-corrosion material. An observation window 2 is provided on one side of the protective helmet 1, and a protective mask 3 is installed in the observation window 2. The protective mask 3 is rotated and retracted along the protective helmet 1, and an arc-shaped moving groove 4 is provided along the outer side of the protective helmet 1. A pushing component for covering and opening the observation window 2 with the protective mask 3 is provided in the moving groove 4. The protective helmet 1 is provided with hearing aids 6 located on both sides of the protective mask 3. The hearing aids 6 penetrate the protective helmet 1, which is convenient for hearing whether there is an abnormal sound inside the valve port during maintenance, thereby improving the accuracy and installation performance during maintenance. A ventilation component for maintaining air circulation inside the protective helmet 1 is provided on the side of the protective helmet 1 facing away from the protective mask 3. The protective helmet 1 is put on the head, and then the protective mask 3 is pushed down so that the protective mask 3 covers the observation window 2 on the protective helmet 1, thereby improving the safety of the valve port for maintenance.

[0022] Reference Figure 4 The pushing assembly includes a pushing plate 5, which is attached to the outer wall of the protective helmet 1, and a connecting rod 12 is provided between the pushing plate 5 and the side wall of the protective mask 3. The protective mask 3 can be folded up by pushing the pushing plate 5 on one side by hand to avoid direct contact between the hand and the protective mask 3, thereby improving the clarity of the protective mask 3 during maintenance.

[0023] Reference Figure 1 The outer side of the push plate 5 is provided with an anti-slip strip 8. Gloves are often worn during maintenance, and the anti-slip strip 8 improves the stability of pushing.

[0024] Reference Figure 2-Figure 3 The ventilation component includes two suction fans 10 and an exhaust fan 11. The two suction fans 10 are arranged on the side of the protective helmet 1 facing away from the protective mask 3. Air is inhaled first from the back to prevent direct contact with the solution in the valve port during inhalation. The exhaust fan 11 is located on the side of the protective helmet 1 close to the hearing aid 6. The exhaust fan 11 is arranged on the side of the protective helmet 1 facing away from the push plate 5. The suction fans 10 and the exhaust fans 11 are both provided with filter plugs 9 on the outward sides, and the gas in the maintenance space is filtered through the filter plugs 9.

[0025] Reference Figure 4 A bucket-shaped suction pipe 7 is provided on the outward side of the exhaust fan 10, and the filter plug 9 is located in the bucket-shaped suction pipe 7 to increase the suction area during suction.

[0026] Reference Figure 4The larger opening end of each hearing aid 6 faces the outside of the protective helmet 1, and the smaller opening end faces the inside of the protective helmet 1. Facing the larger end of the hearing aid 6 to the outside of the protective helmet 1 is conducive to receiving sound, while the smaller opening end faces the inside of the protective helmet 1 to make it easier for the staff to hear clearly.
