[0037] There are two connecting blocks 21, swing rods 22, sliding rings 23, and rectangular bodies 2401 symmetrically arranged along the vertical center line of the sealed tank 14 respectively. Both ends of a first spring 25 are fixedly connected to the sides of the two sliding rings 23 far from the rectangular body 2401 respectively.
[0038] One end of the sealed tank 14 close to the universal wheels 11 is fixedly connected with a second spring 26 and a connecting column 27 respectively. The end of the second spring 26 far from the sealed tank 14 is fixedly connected to the protective shell 1, and the end of the connecting column 27 far from the sealed tank 14 is slidably connected to the protective shell 1.
[0039] The air extraction structure 3 includes a rectangular block 31 fixedly connected to the sliding ring 23. One side of the rectangular block 31 far from the universal wheels 11 is fixedly connected with a first sliding rod 32. The end of the first sliding rod 32 far from the rectangular block 31 is fixedly connected to a fixed sleeve 33. The first sliding rod 32 and the rectangular block 31 are respectively slidably connected to the protective shell 1.
[0040] An elastic column is fixedly connected inside the fixed sleeve 33, and the end of the elastic column far from the fixed sleeve 33 is fixedly connected with a second sliding rod 34. The end of the second sliding rod 34 far from the second sliding rod 34 is magnetically connected to an air extraction port 35, and the air extraction port 35 is connected to the intake end of the air pump 12 through a through connection.
[0041] The sealing mechanism 4 includes a first sliding plate 41 slidably connected to the sealing plate 15. One side of the first sliding plate 41 far from the sealing plate 15 is fixedly connected with a second sliding plate 4101, and a silica gel pad 42 is fixedly connected to the outer side wall of the second sliding plate 4101.
[0042] One side of the sealing plate 15 close to the first sliding plate 41 is fixedly connected with a first rack 43. Two gears 44 are respectively meshed on both sides of the first rack 43. One side of the gear 44 far from the first rack 43 is meshed with a second rack 45, and the side of the second rack 45 far from the gear 44 is fixedly connected to the first sliding plate 41. A rotating column 4401 is fixedly connected inside the gear 44, and the rotating column 4401 is rotatably connected to the sealing plate 15.
[0043] A chute is opened inside the sealing plate 15. The chute opened inside the sealing plate 15 is composed of two circular grooves with different diameters. The four universal wheels 11 are arranged diagonally, and all four universal wheels 11 have a self-locking function.
[0044] The complete working principle and steps of the above embodiments are as follows:
[0045] Reference Figure 2, when this device needs to be used, first, the staff pushes one side of the protective shell 1, and then moves this device to the filling place of chemical products through the four universal wheels 11 installed at the bottom of the protective shell 1. All four universal wheels 11 have a self-locking function. Then, the staff pulls the handle 16, so that the sealing plate 15 slidably connected to the handle 16 is separated from the sealing tank 14. Then, the staff can fill the chemical products into the interior of the sealing tank 14.
[0046] After filling the chemical products, the staff places the sealing plate 15 above the sealing tank 14 by moving the handle 16. Refer to Figure 3 , since the sealing plate 15 is slidably connected to the first sliding plate 41, and one end of the first sliding plate 41 away from the sealing plate 15 is fixedly connected to the second sliding plate 4101. When the staff pulls the handle 16 to place the sealing plate 15 above the sealing tank 14, the handle 16 is slidably connected to the sealing plate 15. Thus, when the staff pulls the handle 16, refer to Figure 4 , the handle 16 can drive the first rack 43 fixedly connected to it to slide away from the sealing plate 15. When the first rack 43 slides away from the second sliding plate 4101, it can drive the gears 44 meshed on both sides to rotate. When the gears 44 rotate, they can drive the second rack 45 meshed on the side away from the first rack 43 to slide away from the handle 16. When the second rack 45 moves, it can drive the first sliding plate 41 to move away from the handle 16. And the chute inside the sealing plate 15 is composed of two circular grooves with different diameters, and the first sliding plate 41 can slide in the chute inside the sealing plate 15. Thus, when the first sliding plate 41 moves to the side away from the handle 16 and is completed;
[0047] At this time, when the staff makes the center of the sealing plate 15 coincide with the center of the sealing tank 14, the second sliding plate 4101 will drive the sealing plate 15 to slide towards the sealing tank 14 by its own weight. Since the outer side wall of the second sliding plate 4101 is fixedly connected with a silica gel pad 42, when the second sliding plate 4101 slides towards the sealing tank 14, it can drive the silica gel pad 42 to slide towards the sealing tank 14. Since the diameter of the silica gel pad 42 is larger than the diameter of the sealing tank 14, refer to Figure 5 , thus when the silica gel pad 42 moves, the edge of the silica gel pad 42 away from the second sliding plate 4101 will be conical, so that the sealing tank 14 can be sealed by the silica gel pad 42.
[0048] After the movement of the sealing plate 15 is completed, the side of the sealing plate 15 away from the handle 16 will abut against one end of the sealing tank 14 away from the universal wheel 11. At this time, by the staff pressing the handle 16 towards the side close to the sealing tank 14, the handle 16 drives the first rack 43 to slide towards the side close to the sealing tank 14. When the first rack 43 slides towards the side close to the sealing tank 14, it can drive the gears 44 meshed on both sides to rotate. When the gears 44 rotate, they can drive the second rack 45 meshed on the side away from the first rack 43 to slide away from the sealing tank 14. When the second rack 45 moves, it can drive the first sliding plate 41 to move away from the sealing tank 14;
[0049] When the first sliding plate 41 moves, it can drive the second sliding plate 4101 fixedly connected thereto to slide away from the sealing tank 14. When the second sliding plate 4101 moves, it can drive the silica gel pad 42 fixedly connected to the outer wall to slide away from the sealing tank 14. And before pressing the handle 16, the edge of the silica gel pad 42 away from the second sliding plate 4101 will be conical. At this time, when the silica gel pad 42 moves away from the handle 16, refer to Figure 6 , the center of the silica gel pad 42 will move away from the handle 16 along with the second sliding plate 4101, so that the silica gel pad 42 is in the same horizontal state as the sealing tank 14.
[0050] After the silica gel pad 42 moves away from the sealing tank 14, the inside of the sealing tank 14 can be in a negative pressure state. And because the silica gel pad 42 is in the same horizontal state as the sealing tank 14, the inside of the sealing tank 14 can be sealed more tightly.
[0051] Refer to Figure 2 , after the sealing tank 14 is sealed, the staff can push the protective shell 1, and then move the chemical products inside the sealing tank 14 to the designated position through the universal wheels 11 fixedly connected to the bottom of the protective shell 1.
[0052] When the protective shell 1 bumps up and down on a bumpy section during the movement, the protective shell 1 will squeeze the second spring 26 upwards. And since the sealing tank 14 is slidably connected to the protective shell 1, the sealing tank 14 will not move, thus avoiding damage or leakage of the sealing tank 14 slidably connected inside the protective shell 1 due to road bumps.
[0053] At this time, the second spring 26 is in a compressed state. When the protective shell 1 no longer squeezes the second spring 26 due to the road section, the second spring 26 will release the pressure, so that the protective shell 1 moves away from the sealing tank 14, so that the universal wheels 11 can always be in full contact with the ground.
[0054] Refer to Figure 2, when the protective shell 1 slides towards or away from the sealed tank 14, it can drive the connecting block 21 to move up and down. When the connecting block 21 moves, the swing rod 22 rotatably connected to it can swing. When the swing rod 22 swings, it can drive the sliding ring 23 rotatably connected to it to slide left and right on the outside of the fixed column 24. When the sliding ring 23 slides, it can drive the fixed sleeve 33 to slide on the outer side wall of the sealed tank 14 through the rectangular block 31. The fixed sleeve 33 is slidably connected to the second sliding rod 34 through an elastic column, and the end of the second sliding rod 34 away from the fixed sleeve 33 is magnetically connected to the air extraction port 35. Therefore, when the fixed sleeve 33 moves, it can drive the air extraction port 35 to slide in the inner side wall of the sealed tank 14 through the second sliding rod 34;
[0055] And when the device moves, the staff can control the remote controller 13 to start the air pump 12 electrically connected to it. The air inlet end of the air pump 12 is in through connection with the air extraction port 35. Therefore, through the cooperation of the air extraction port 35 and the air pump 12, the harmful gases accumulated inside the sealed tank 14 due to the accumulation of chemical plant products can be extracted, avoiding the damage to the staff's body caused by the harmful gases inside the sealed tank 14 after the staff opens the sealing plate 15.
[0056] Moreover, the distance of the up and down movement of the protective shell 1 can be determined by the swinging range of the swing rod 22. Therefore, through the swing rod 22, the distance that the first spring 25 slides on the outside of the fixed column 24 can be different. Then, through the cooperation between the first sliding rod 32, the fixed sleeve 33, and the second sliding rod 34, the air extraction port 35 can collect harmful gases at different positions inside the sealed tank 14, collecting the harmful gases inside the sealed tank 14 more thoroughly.
[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
