Specific embodiments

[0024] The following will disclose multiple embodiments of the present utility model in the form of diagrams. For the sake of clarity, many physical details will be described together in the following narrative. However, it should be understood that these physical details are not used to limit the present utility model. That is to say, in some embodiments of the present utility model, these physical details are not necessary. In addition, for the sake of simplifying the diagrams, some conventional structures and components will be shown in a simple schematic manner in the diagrams.

[0025] Please refer to Figure 1 , Figure 2 , Figure 6 , the fresh air device of the tank truck of the present utility model includes a tank body 1 and a large plastic manhole cover 2. An air outlet is provided at the rear end of the tank body 1. The large plastic manhole cover 2 is connected and installed on the tank body 1. An apron 3 is provided on the tank body 1 around the large plastic manhole cover 2. A cover plate 4 is provided on the apron 3. An air deflector 6 is rotatably installed on the apron 3. A chute 9 is provided on the air deflector 6. A limiting component is provided between the chute 9 and the apron 3.

[0026] After the vehicle unloads the goods, pull up the air deflector 6 to open the upper end of the apron 3, and open the large plastic manhole cover 2, and fix the position of the air deflector 6 through the limiting component. When the vehicle is driving, use the vehicle speed to quickly make the air enter the inside of the apron 3 from the opening between the air deflector 6 and the apron 3, and enter the inside of the tank body 1 through the large plastic manhole cover 2, so as to form a positive pressure inside the tank body 1, and thus discharge the remaining gas in the tank from the air outlet at the rear of the tank body 1, thereby reducing the oxidation corrosion of the inner lining of the tank body 1 by the remaining gas and extending the service life.

[0027] Such as Figure 2 , Figure 3 , Figure 4, the limiting component includes a bolt 7. The bolt 7 passes through the shroud 3 and the chute 9. One end of the bolt 7 is provided with a hexagonal nut, and the other end of the bolt 7 is provided with a wing nut 8. The staff drives the wing nut 8 or the hexagonal nut to rotate on the bolt 7 through tools, so as to adjust the distance between the wing nut 8 and the hexagonal nut. When the distance between the wing nut 8 and the hexagonal nut gradually increases, the extrusion force between the shroud 3 and the air deflector 6 is reduced, and the fixation between the air deflector 6 and the shroud 3 is released. When the distance between the wing nut 8 and the hexagonal nut gradually decreases, the extrusion force between the shroud 3 and the air deflector 6 is increased, and the fixation between the air deflector 6 and the shroud 3 is realized.

[0028] As Figure 4 , Figure 6 shown, one end of the air deflector 6 is provided with a baffle 10. The baffle 10 is installed on the lower end surface of the air deflector 6. The baffle 10 is arranged in an "L" shape. The air flow entering between the air deflector 6 and the shroud 3 is guided through the baffle 10, so as to improve the efficiency of air entering the tank body 1 through the large plastic manhole cover 2.

[0029] One end of the cover plate 4 is rotatably connected to the shroud 3 through a hinge 5. A fixing member is arranged between the other end of the cover plate 4 and the shroud 3. There are two hinges 5, and the two hinges 5 are symmetrically arranged. The connection stability can be improved through the hinge 5, and the stability between the cover plate 4 and the shroud 3 is reduced.

[0030] As Figure 4 , Figure 5 shown, the fixing member includes a fixing cylinder 12. One end of the fixing cylinder 12 is slidably provided with a telescopic cylinder 13. The other end of the fixing cylinder 12 is provided with a fixing head 18. The fixing head 18 is threadedly connected to the fixing cylinder 12. A spring 16 is arranged between the fixing head 18 and the telescopic cylinder 13. A damping rod is arranged inside the spring 16. One end of the damping rod is rotatably connected to the fixing head 18. A vertical plate 11 is arranged on the side of the telescopic cylinder 13 away from the fixing head 18. The vertical plate 11 is fixedly installed on the cover plate 4.

[0031] When it is necessary to release the restriction of the cover plate 4, the staff drives the fixing head 18 to rotate and separate from the fixing cylinder 12, so as to release the restriction on the spring 16, drag the fixing head 18 to move. The fixing head 18 drives the telescopic cylinder 13 to move through the damping rod and the spring 16. One end of the telescopic cylinder 13 moves away from the vertical plate 11, so as to release the restriction on the vertical plate 11, and the cover plate 4 can rotate. By driving the fixing head 18 to move in the reverse direction, the fixing head 18 is fixed on the fixing cylinder 12, and one end of the telescopic cylinder 13 restricts the vertical plate 11, so as to restrict the position between the shroud 3 and the cover plate 4.

[0032] A clamping groove 15 is provided on the vertical plate 11, and a stopper 14 is installed on the telescopic cylinder 13. The stopper 14 is inserted into the clamping groove 15. By means of the stopper 14 and the clamping groove 15, the contact area with the vertical plate 11 is increased, and the blocking effect on the vertical plate 11 is improved. A rib plate 17 is arranged below the stopper 14. The rib plate 17 is installed on the inner wall of the surrounding plate 3 to support the stopper 14 and prevent the stopper 14 from dropping, which may affect the connection between the stopper 14 and the clamping groove 15 and cause unstable positioning.

[0033] The above are only the embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
