[0011] Preferably, there are multiple extension rods, and multiple extension rods penetrate the hollow plate.

[0012] The present invention provides an emission protection device for a nitrogen generator, which has the following beneficial effects:

[0013] 1. Through the cooling mechanism, a freezer and a water tank are placed inside the cargo box of the truck, and a refrigerator is stored inside the freezer. The truck driver takes out the ice cubes in the freezer and puts the ice cubes and water into the inside of the base through the water inlet. According to common sense, the ice cubes can be quickly dissolved in the water through continuous stirring. The specific stirring method is as follows: start the motor to drive the shaft to rotate, and the rotation of the shaft drives the diamond plate and the disc to rotate. When the diamond plate rotates, the second protrusion contacts and passes through the first stopper. In this process, the slide plate can be driven to slide on the outside of the slide rail toward the direction of the disc. After that, the first protrusion contacts the top of the vertical rod, and then the vertical rod is rotated. The bottom of the vertical rod rotates and contacts the second stopper and passes through. The sliding plate passes through the second block. During this process, the sliding plate moves in the opposite direction outside the sliding rail, which is conducive to the reciprocating movement of the sliding plate and the water pushing plate through the rotation of the diamond plate. The reciprocating movement of the water pushing plate stirs the water in the base. When the disc rotates, the sliding sleeve is driven to slide on the outside of the sliding rod through the connecting rod. During the sliding process, the sliding rod rotates with the placement plate and the support rod. When the support rod rotates, it drives the first water stirring plate to stir the water. The rotation of the placement plate drives the second water stirring plate to stir the water. Through the above multiple stirrings, the ice cubes are quickly dissolved in the water to form cooling water to cool the base. After the base is cooled, the low temperature is transmitted to the nitrogen generator to cool the nitrogen generator, thereby preventing the high temperature from damaging the internal components of the nitrogen generator and achieving protection through cooling.

[0014] 2. Through the clamping mechanism, open the box door and put the spare parts used in the nitrogen generator into the inside of the parts box, put the plate-shaped parts on the top of the horizontal plate, and put the irregular parts between the two hollow plates. The output end of the cylinder extends out to drive the triangular plate to rotate. When the triangular plate rotates, it drives the two first connecting rods to rotate in the opposite direction. The two first connecting rods rotate in the opposite direction to drive the two pressure rods to rotate in the opposite direction. Then the two pressure rods press the top of the pressure plate and compress the spring to make the pressure plate drop. When the pressure plate drops, the plate-shaped parts on the top of the horizontal plate can be pressed to prevent the parts from shaking and causing damage during transportation. When the output end of the cylinder retracts, the pressure rod leaves the top of the pressure plate, and then the spring drives the pressure plate to rise and reset to release the plate-shaped parts. When the output end of the cylinder extends out to drive the triangular plate to rotate, the cylinder and the second connecting rod will have a downward rotation. When the second connecting rod rotates downward, the rectangular plate is driven to slide downward along the slide groove through the vertical rod. The downward movement of the slide groove drives the two third connecting rods to rotate in the opposite direction, and then the two connecting blocks and the two hollow plates rotate in the opposite direction. The reverse rotation of the hollow plate is conducive to clamping the irregular accessories. The specific clamping is as follows: the upper and lower widths of the irregular accessories are different. When the accessories are of different widths, the inner sides of the two hollow plates can only clamp the widest position of the accessories, but the narrowest position of the accessories will not be clamped. At this time, through the set extension rod, the widest position of the accessory will be supported by the extension rod in contact with it, and the widest part of the part will be limited and fixed. A part of the supported extension rod will return to the inside of the hollow plate, and the returned extension rod will cause the corresponding position of the airbag to sink. The narrowest part of the accessory will also contact the extension rod, but the extension rod here will not return to the hollow plate. At this time, the narrowest part of the accessory is wrapped by the extension rod, and the narrowest part of the accessory is limited and clamped by making the extension rod wrap the narrowest part of the accessory. Through the above operation, the outside of the entire irregular accessory is wrapped by the extension rod, thereby improving the clamping effect of the hollow plate on the irregular accessory. When the irregular accessory is taken out from the two hollow plates, the sunken position of the airbag will re-extend to the outside of the hollow plate under the action of elastic reset.

[0025] Specifically, the starting motor 4 drives the rotating shaft 5 to rotate, and the rotation of the rotating shaft 5 drives the diamond plate 6 and the disc 19 to rotate. When the diamond plate 6 rotates, the second protrusion 8 contacts with the first stopper 12 and passes through the first stopper 12. In this process, the slide plate 11 can be driven to slide toward the disc 19 outside the slide rail 10. After that, the first protrusion 7 contacts with the top of the vertical rod 9, and then the vertical rod 9 is rotated. The vertical rod 9 rotates and its bottom contacts with the second stopper 13 and passes through the second stopper 13. In this process, the slide plate 11 moves in the opposite direction outside the slide rail 10, which is conducive to realizing the slide plate 1 through the rotation of the diamond plate 6. 1 and the water-pushing plate 14 reciprocate, and the reciprocating movement of the water-pushing plate 14 stirs the water in the base 1. When the disc 19 rotates, the sliding sleeve 18 is driven to slide on the outside of the sliding rod 17 through the connecting rod 20. During the sliding process, the sliding rod 17 rotates with the placement plate 16 and the support rod 15.

Through the above multiple stirrings, the ice cubes are quickly dissolved in the water to form cooling water to cool the base 1. After the base 1 is cooled, the low temperature is transmitted to the nitrogen generator 2 to cool the nitrogen generator 2.

[0026] Example 2

[0027] Focus on reference Figure 3-5The clamping mechanism includes a cylinder 23 and a triangular plate 24 rotatably installed inside the accessory box 3, the output end of the cylinder 23 is rotatably connected to the first corner of the triangular plate 24, and the other two corners of the triangular plate 24 are rotatably connected to the first connecting rod 25, a horizontal plate 26 is fixedly arranged inside the accessory box 3, and pressure rods 27 are rotatably connected on both sides of the horizontal plate 26, and springs 28 are fixedly arranged on both sides of the top of the horizontal plate 26, and a pressure plate 29 is fixedly arranged on the top of the spring 28, and a second connecting rod 30 is fixedly arranged on the outside of the cylinder 23, a slide groove 31 is arranged inside the accessory box 3, and a rectangular plate 32 is slidably connected to the outside of the slide groove 31, and a vertical Rod 33, the top of the second connecting rod 30 is rotatably connected to the bottom of the vertical rod 33, the interior of the accessory box 3 is rotatably connected with a connecting block 34, the two sides of the front surface of the rectangular plate 32 are rotatably connected with the third connecting rod 35, the top of the third connecting rod 35 is rotatably connected to one side of the connecting block 34, a hollow plate 36 is fixedly arranged on the inner side of the connecting block 34, an air bag 37 is fixedly arranged inside the hollow plate 36, an extension rod 38 is fixedly arranged on one side of the air bag 37, the number of the first connecting rod 25 and the pressure rod 27 are both two, one first connecting rod 25 is rotatably connected to the first pressure rod 27, the number of the extension rod 38 is multiple, and multiple extension rods 38 pass through the hollow plate 36;

[0028] Specifically, open the box door and put the spare parts used by the nitrogen generator 2 into the inside of the parts box 3, put the plate-shaped parts on the top of the cross plate 26, and put the irregular parts between the two hollow plates 36. The output end of the cylinder 23 extends to drive the triangular plate 24 to rotate. When the triangular plate 24 rotates, it drives the two first connecting rods 25 to rotate in the opposite direction. The two first connecting rods 25 rotate in the opposite direction and drive the two pressure rods 27 to rotate in the opposite direction. Then the two pressure rods 27 press the top of the pressure plate 29 and compress the spring 28 to make the pressure plate 29 drop. When the pressure plate 29 drops, it can press the plate-shaped parts on the top of the cross plate 26 to prevent the parts from shaking and causing damage during transportation. When the output end of the cylinder 23 retracts, the pressure rod 27 leaves the top of the pressure plate 29, and then the spring 28 drives the pressure plate 29 to rise and reset to loosen the plate-shaped accessories. When the output end of the cylinder 23 extends to drive the triangular plate 24 to rotate, the cylinder 23 and the second connecting rod 30 will have a downward rotation. When the second connecting rod 30 rotates downward, it drives the rectangular plate 32 to slide downward along the slide groove 31 through the vertical rod 33. The downward movement of the slide groove 31 drives the two third connecting rods 35 to rotate in the opposite direction, and then the two connecting blocks 34 and the two hollow plates 36 rotate in the opposite direction. The reverse rotation of the two hollow plates 36 is conducive to clamping the irregular accessories.

[0029] Working principle: a freezer and a water tank are placed inside the cargo box of the truck, and a refrigerator is stored inside the freezer. The truck driver takes out the ice cubes in the freezer and puts the ice cubes and water into the base 1 through the water inlet. According to common sense, the ice cubes can be quickly dissolved in the water through continuous stirring. The specific stirring method is as follows: start the motor 4 to drive the rotating shaft 5 to rotate, and the rotation of the rotating shaft 5 drives the diamond plate 6 and the disc 19 to rotate. When the diamond plate 6 rotates, the second protrusion 8 contacts with the first stopper 12 and passes through the first stopper 12. In this process, the slide plate 11 can be driven to slide on the outside of the slide rail 10 toward the direction of the disc 19. After that, the first protrusion 7 will contact with the top of the vertical rod 9, and then the vertical rod 9 will rotate. The vertical rod 9 rotates and its bottom contacts with the second stopper 13 and passes through. The slide plate 11 passes through the second stopper 13. During this process, the slide plate 11 moves in the opposite direction outside the slide rail 10, which is conducive to the reciprocating movement of the slide plate 11 and the water pushing plate 14 through the rotation of the diamond plate 6. The reciprocating movement of the water pushing plate 14 stirs the water in the base 1. When the disc 19 rotates, the sliding sleeve 18 is driven to slide on the outside of the slide rod 17 through the connecting rod 20. During the sliding process, the slide rod 17 rotates with the placement plate 16 and the support rod 15. When the support rod 15 rotates, it drives the first water stirring plate 21 to stir the water. The placement plate 16 rotates and drives the second water stirring plate 22 to stir the water. Through the above multiple stirrings, the ice cubes are quickly dissolved in the water to form cooling water to cool the base 1. After the base 1 is cooled, the low temperature is transmitted to the nitrogen generator 2 to cool the nitrogen generator 2 to prevent high temperature. The internal components of the nitrogen generator 2 are damaged and protected by cooling. The box door is opened to put the spare parts used by the nitrogen generator 2 into the inside of the parts box 3, the plate-shaped parts are placed on the top of the cross plate 26, and the irregular parts are placed between the two hollow plates 36. The output end of the cylinder 23 extends to drive the triangular plate 24 to rotate. When the triangular plate 24 rotates, it drives the two first connecting rods 25 to rotate in the opposite direction. The two first connecting rods 25 rotate in the opposite direction to drive the two pressure rods 27 to rotate in the opposite direction. Then the two pressure rods 27 press the top of the pressure plate 29 and compress the spring 28 to make the pressure plate 29 drop. When the pressure plate 29 drops, the plate-shaped parts on the top of the cross plate 26 can be pressed to prevent the parts from shaking and causing damage during transportation. When the output end of the cylinder 23 is retracted, the pressure rod 2 7 leaves from the top of the pressure plate 29, and then the spring 28 drives the pressure plate 29 to rise and reset to loosen the plate-shaped accessories. When the output end of the cylinder 23 extends to drive the triangular plate 24 to rotate, the cylinder 23 and the second connecting rod 30 will have a downward rotation movement. When the second connecting rod 30 rotates downward, the vertical rod 33 drives the rectangular plate 32 to slide downward along the slide groove 31. The downward movement of the slide groove 31 drives the two third connecting rods 35 to rotate in the opposite direction, and then the two connecting blocks 34 and the two hollow plates 36 rotate in the opposite direction. The reverse rotation of the two hollow plates 36 is conducive to clamping the irregular accessories. The specific clamping is as follows: the upper and lower widths of the irregular accessories are different. When the accessories are of different widths, the inner sides of the two hollow plates 36 can only clamp the widest position of the accessories.However, the narrowest part of the accessory will not be clamped. At this time, the widest part of the accessory will be supported by the extension rod 38 in contact with it through the setting of the extension rod 38, and the widest part of the part will be limited and fixed. A part of the supported extension rod 38 will return to the inside of the hollow plate 36, and the returned extension rod 38 will cause the corresponding position of the airbag 37 to be recessed. The narrowest part of the accessory will also contact the extension rod 38, but the extension rod 38 here will not return to the hollow plate 36. At this time, the narrowest part of the accessory is wrapped by the extension rod 38. The narrowest part of the accessory is wrapped by the extension rod 38 to limit and clamp the narrowest part of the accessory. Through the above operation, the outside of the entire irregular accessory is wrapped by the extension rod 38, which improves the clamping effect of the hollow plate 36 on the irregular accessory. When the irregular accessory is taken out of the two hollow plates 36, the recessed position of the airbag 37 will re-extend to the outside of the hollow plate 36 under the elastic reset effect.

[0030] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
