[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figure 1 、 Figure 3 and Figure 5 , an embodiment provided by the present invention: a safety protection device for the renovation construction of a hot blast stove, including a column 1. A rotating ring 3 is rotatably connected to the outer wall of the column 1. A rotating piece 4 is rotatably connected to the right side of the middle part of the rotating ring 3. The right end of the rotating piece 4 is fixedly connected to a telescopic rod 1 5. The upper middle part of the telescopic rod 1 5 is threadedly connected to a telescopic rod 4 8. The lower middle part of the telescopic rod 4 8 is threadedly connected to a telescopic rod 3 7. The telescopic rod 4 8 is threadedly connected to the upper middle part of the telescopic rod 2 6. A pin hole 1 9 is opened inside the column 1. A pin rod 12 is installed inside the pin hole 1 9. A vertical rod 11 is slidably connected inside the column 1. A pin hole 2 10 is opened on the right side of the outer wall of the vertical rod 11. A safety net 13 is fixedly connected to the upper middle part of the outer wall of the vertical rod 11. A water storage box 16 is fixedly connected to the rear side of the outer wall of the column 1. A micro water pump 17 is installed inside the water storage box 16. One end of the micro water pump 17 is installed with an atomizing nozzle 18. A bracket mechanism 2 is fixedly connected to the upper middle part of the column 1. The bracket mechanism 2 is used to adjust the angle of the safety net. The atomizing nozzle 18 is threadedly connected to a hinge 20 at the rear side. The bottom of the outer wall of the hinge 20 is rotatably connected to a baffle 19. A hook 28 is fixedly connected to the front side of the outer wall of the column 1. A warning sign 29 is installed on the front side of the outer wall of the hook 28;

[0033] Specifically, when the column 1 is dragged forward, the fence unfolds forward, ensuring the extensibility of the fence. There is a vertical rod 11 placed inside the column 1. By pulling it upward, the height of the column 1 can be increased, thereby increasing the height of the fence. Using the pin hole one 9 on the outer wall of the column 1 and the pin hole two 10 on the outer wall of the vertical rod 11, the height of the protective net 13 installed at the top of the vertical rod 11 can be determined. The determined height can fix the height requirement of the protective net 13 with a pin rod 12. By using the water storage box 16 fixed on the rear outer wall of the column 1, dust reduction and ash discharge can be achieved. In the upper middle part of the column 1, a bracket mechanism 2 is fixedly installed. This mechanism is used to adjust the angle of the safety net to meet the requirements of different construction sites. A fog nozzle 18 is installed on the upper part of the water storage box 16. The fog nozzle 18 can effectively spray water mist to complete dust reduction around the fence. The rear side of the fog nozzle 18 is connected to a hinge 20 by a thread, and the bottom outer wall of the hinge 20 is rotatably connected to a baffle 19. The baffle 19 can prevent foreign objects from entering the water storage box 16. In addition, a hook 28 is fixedly installed on the front outer wall of the column 1 for conveniently placing a warning sign 29;

[0034] Refer to Figure 2 、 Figure 3 and Figure 4 Figure, the bracket mechanism 2 includes a ratchet disc 201. The ratchet disc 201 is rotatably connected to the upper middle part of the column 1. Inside the ratchet disc 201, there is a rotating disc 202 rotatably connected. A fixed column 203 is fixedly connected to the outer wall of the rotating disc 202. A spring piece 204 is installed on the outer wall of the fixed column 203. The upper end of the spring piece 204 is rotatably connected to a ratchet 205. A dial 206 is fixedly installed on the outer side of the ratchet 205. The rotating disc 202 is fixedly connected to the outer wall of the connecting block 207. A screw one 208 is threadedly connected to the top of the connecting block 207. The top end of the outer wall of the screw one 208 is threadedly connected to a concave bracket 209. A convex bracket 210 is threadedly connected to the top of the concave bracket 209. A circular ring 211 is fixedly connected to the rear side of the outer wall of the convex bracket 210. The protective net 13 is fixedly connected to the top of the hook 212. The bottom end of the column 1 is fixedly connected to a footrest 21. Anti-slip sleeves 22 are threadedly connected to the front and rear ends of the footrest 21. A screw two 23 is threadedly connected to the upper end of the anti-slip sleeve 22. A leg 24 is fixedly connected to the outer wall of the footrest 21. A pulley 25 is rotatably connected to the outer wall of the leg 24;

[0035] Specifically, after the height of the protective net 13 is determined, the protective angle of the protective net 13 can be improved by adjusting the ratchet disc 201. Lift the connecting block 207 upward. The pawl 205 inside the ratchet disc 201 rotates clockwise and contracts inward, squeezing the spring piece 204. The reaction force of the spring piece 204 pushes the pawl 205 upward to make the pawl 205 return to its position. At the same time, the angles of the concave bracket 209 and the convex bracket 210 change. A circular ring 211 is fixed on the outer wall at the rear side of the convex bracket 210. The bottom of the protective net 13 is fixedly connected to the hook 212. Through the circular ring 211 and the hook 212, the connection between the protective net 13 and the bracket is realized. The bottom of the upright column 1 is connected to the footrest 21. Both the front and rear ends of the footrest 21 are connected to the anti-slip sleeve 22 through threads. The upper end of the anti-slip sleeve 22 is connected to the screw two 23 through threads. The anti-slip sleeve 22 can increase the friction with the ground and keep the guardrail upright. A leg 24 is fixed on the outer wall of the footrest 21, and a pulley 25 is rotatably connected to the outer wall of the leg 24. The pulley 25 can assist the construction workers in laying the fence.

[0036] Refer to Figure 1 , Figure 3 and Figure 4 , a handle 26 is fixedly connected to the front side of the middle part of the outer wall of the upright column 1. A storage box 27 is arranged on the left side of the handle 26. The top end of the upright rod 11 is fixedly connected to a base 14, and a warning light 15 is installed inside the base 14;

[0037] Specifically, the handle 26 fixed on the upright column 1 can help the construction workers quickly lay the fence. The storage box 27 on the left side of the handle 26 can store the parts of the construction workers and prevent the loss of items. A warning light 15 is installed at the top of the upright rod 11. The base 14 at the bottom of the warning light 15 can prevent it from being eroded by rainwater, play a warning role, and prevent the workers from being injured.

[0038] Working principle: The construction workers drag the upright column 1 forward by pulling the handle 26 on the front side of the outer wall of the upright column 1, and the fence unfolds forward. The rotating ring 3 on the outer wall of the upright column 1 can make the telescopic rod and the upright column 1 independent of each other and connected together. A rotating piece 4 is fixedly connected to the bottom of the first telescopic rod 5 on the right side of the rotating ring 3. The top of the third telescopic rod 7 is fixedly connected to the rotating piece 4. The bottom of the telescopic rod is fixedly connected to the rotating piece 4 in the middle and lower part of the upright column 1. When the upright column 1 moves forward, the telescopic rods contract, ensuring the ductility of the fence. An upright rod 11 is placed inside the upright column 1. By pulling upward, the height of the upright column 1 can be increased to ensure the safe construction range. Using the pin hole one 9 on the outer wall of the upright column 1 and the pin hole two 10 on the outer wall of the upright rod 11, the height of the protective net 13 installed at the top of the upright rod 11 can be determined, and the determined height can be fixed by the pin rod 12 according to the height requirement of the protective net 13.

[0039] The protection angle of the protection net 13 can be further improved by adjusting the ratchet disc 201. The specific operation method is to lift the connecting block 207 upward. At this time, the pawl 205 inside the ratchet disc 201 will rotate clockwise and contract inward. As the pawl 205 contracts, it squeezes the spring piece 204, and the spring piece 204 will generate a reaction force. This reaction force will push the pawl 205 upward to make it return to its original position. At the same time, the angle between the concave bracket 209 and the convex bracket 210 will change, thus completing the angle adjustment. In this way, we can use the folding bracket to adjust the area requirement of the protection net 13 to ensure that the protection net 13 can better meet the actual use requirements.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
