DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 , the utility model provides a technical solution: Example

[0027] A ventilation device for protective engineering includes a water injection pipe 1, the right end of the water injection pipe 1 is connected to a water washing structure, the top left end of the water washing structure is connected to a filtering and cleaning structure, and the top right end of the water washing structure is connected to an adsorption structure.

[0028] The filtering and cleaning structure includes a cleaning and collecting unit and a filtering unit. The cleaning and collecting unit includes an electric push rod 204. The output end of the electric push rod 204 is connected to a linkage plate 205. The bottom surface of the linkage plate 205 is connected to a mounting plate 206. The bottom end of the mounting plate 206 is connected to a cleaning brush 207. A guide rail 208 is provided at the bottom of the cleaning brush 207. The outer surface of the guide rail 208 is connected to a dust collection box 209. An electrostatic dust collection plate 210 is installed inside the dust collection box 209. The filtering unit includes an air inlet 201. An air inlet fan 202 is installed at the left end of the air inlet 201. A filter plate 203 is installed inside the air inlet 201.

[0029] The bottom surface of the electric push rod 204 is connected to the middle part of the top surface of the air inlet duct 201 near the left end, the outer surface of the mounting plate 206 is slidingly connected to the inner wall of a rectangular hole opened in the middle part of the top surface of the air inlet duct 201, the outer surface of the cleaning brush 207 is slidingly connected to the middle part of the left side of the filter plate 203, the outer surface of the filter plate 203 is sealed and slidingly connected to the inner wall of a rectangular through hole opened in the middle part of the top surface of the air inlet duct 201, the bottom surface of the air inlet duct 201 is fixedly connected to the top surface of the guide rail 208, and the top surface of the dust box 209 is sealed and slidingly connected to the middle part of the bottom surface of the air inlet duct 201.

[0030] By setting up the filtering and cleaning structure, the electric push rod 204 is used to drive the linkage plate 205 and the mounting plate 206 to rise and fall, thereby driving the cleaning brush 207 to brush the surface of the filter plate 203, and utilizing the electrostatic dust collecting plate 210 and the through holes opened at the bottom of the air inlet duct 201 to adsorb dust, thereby facilitating the collection of dust using the dust collecting box 209, preventing the filter plate 203 from being clogged by dust, and preventing dust from affecting subsequent use due to replacement of the filter plate 203.

[0031] During ventilation, the air intake fan 202 is started to transport the external airflow through the air intake duct 201. When the airflow passes through the filter plate 203, the filter plate 203 is used to block and filter the dust in the airflow. Then, the electric push rod 204 is started to drive the linkage plate 205 and the mounting plate 206 to rise and fall. The mounting plate 206 is used to drive the cleaning brush 207 to brush back and forth on the surface of the filter plate 203, so as to prevent the dust from clogging the filter plate 203. After the dust is brushed off, the through hole opened at the bottom of the air intake duct 201 can be used to allow the dust to enter the dust box 209. The electrostatic dust collecting plate 210 can be used to further adsorb the dust particles, so as to prevent the dust particles from affecting the subsequent use when the filter plate 203 is replaced. The sliding connection between the dust box 209 and the guide rail 208 facilitates the disassembly of the dust box 209, so as to centrally process the dust. Example

[0034] By setting up the water washing structure and the adsorption structure, the air inlet pipe 102 is used to pass into the liquid below the liquid level inside the water washing box 101, so that the cleaning liquid inside the water washing box 101 can be used to further clean and adsorb the dust particles in the air flow, and after the air flow enters the air outlet duct 301 through the air outlet pipe 105, the adsorption plate 302 can be used to further adsorb impurities in the gas, and the heating tube 304 can be used to dry the moisture in the air flow, so that the air will not be too humid.

[0035] After the airflow is filtered by the filtering structure, it enters the water washing box 101 through the air inlet pipe 102. The impurities and dirt in the airflow can be further adsorbed and washed by using the cleaning liquid in the water washing box 101 and the air inlet pipe 102 below the liquid level. Then, the airflow enters the air outlet duct 301 through the air outlet pipe 105. After the impurities and moisture in the airflow are further adsorbed by the adsorption plate 302, the humid water vapor in the air is dried by turning on the heating tube 304, and the outlet fan 305 is started for blowing and ventilation, thereby effectively preventing the air entering the engineering protection structure from being too humid. The sewage after water washing can be discharged through the drain pipe 103 by opening the water valve 104.
