[0027] Figure 11 This is a schematic diagram of the loading and unloading state when the tail of the top plate is raised in Example 3. Detailed Implementation Example 1

[0028] like Figures 1 to 3 As shown, an arc-shaped, wind-resistant container includes side panels 1, a top panel, and a rear door 3. Side panels 1 are flat structures, with a higher front and lower rear, and an upper side beam 4 is fixedly connected to the top of side panels 1. The top panel is a movable top panel 2 structure, whose rear end has a lowering function due to the curvature of the steel plate. Lifting plates 5 are located on both sides of the movable top panel 2. Each lifting plate 5 consists of two interlocking and sliding C-shaped plates, as shown... Figure 5 As shown, the bottom of one fixed C-shaped plate is fixedly connected to the upper side beam 4, and the top of the other lifting C-shaped plate is bent inward to form a movable top side beam 6. The front end of the movable top side beam 6 is welded and fixed to the upper side beam 4 at the overlapping position. The movable top side beam 6 has a certain curvature, and its tail follows the tail of the movable top plate 2 as it descends.

[0029] Several fixed square tubes are installed inside the fixed C-shaped plate. The guide column 14 for lifting is slidably connected inside the fixed square tube. The top of the guide column 14 is connected to the positioning piece at the top of the lifting C-shaped plate through a rotating shaft. This not only ensures that the tail of the lifting C-shaped plate can descend freely, but also prevents the cargo inside the container from squeezing or inflating the lifting plate 5, which could lead to the lifting plate failing to lift.

[0030] To achieve the goal of lowering the rear end and reducing wind resistance, the rear door 3 and rear pillar 7 of this application each have a height-lifting structure. For those skilled in the art, a lifting structure in which the fixed plate and the movable plate slide relative to each other can be designed based on common technical knowledge. A lifting power device 8 is provided inside the rear pillars 7 on both sides of the rear door 3. The rear end of the movable top plate 2 and the lifting structure of the rear door 3 are connected to the movable end of the lifting power device 8. Figure 2 As shown, the rear of the movable top panel 2 rises, conforming to the dimensions of a normal container; as Figure 3As shown, when the goods cannot fill the record box, the tail of the movable top plate 2 can be lowered to form a structure of high front and low back, reduce wind resistance and reduce fuel consumption. The lifting power device 8 can use hydraulic cylinder or pneumatic cylinder according to the size of the container and the weight of the movable top plate 2.

[0031] As shown in Figure 4 , due to the slight deviation of the tail of the movable top plate 2 during lifting, the corner piece 9 at the top of the rear door 3 is fixedly welded with a connecting piece 10, and the connecting piece 10 has a long hole, which solves the problem of movement deviation; the movable top side beam 6 is movably connected with the long hole on the connecting piece 10 through a pin shaft, and the movable part of the lifting power device 8 is connected with the connecting piece 10 or the corner piece 9. Example two

[0032] As shown in Figure 6 , an arc-shaped top descending wind resistance container includes side plates 1, a top plate and a rear door 3, wherein the side plates 1 are corrugated plate structures, the top plate is divided into a fixed top plate and a movable top plate 2, the fixed top plate is located at the front end of the carriage, the movable top plate 2 is located at the rear end, and part of the length of the top plate serves as the movable top plate 2, and the tail thereof has a descending function due to the bending curvature of the steel plate; the side plates 1 are high in front and low in back, and the top of the side plates 1 is fixedly connected with an upper side beam 4; the lifting plate 5 is connected with the movable top side beam 6 on both sides of the movable top plate 2, and the lifting plate 5 has a whole C-shaped buckle structure; the bottom of the lifting plate 5 extends below the upper side beam 4 and is in sliding cooperation with the side plates 1.

[0033] Since the movable top plate 2 is part of the length of the top, the starting point of the overall descent is delayed, when the length of the carriage is greater than 15 meters or the lifting height is small, the movable top side beam 6 is one, and the tail can be lowered through the bending curvature, when the length of the carriage is less than 15 meters or the lifting height is large, the top side beam is divided into fixed and movable structures, and the front end of the movable top side beam 6 is connected with the fixed top side beam through a hinge 15, as shown in Figure 7 .

[0034] When the front end of the movable top side beam 6 is connected with the fixed top side beam through the hinge, the rear end of the fixed top plate is provided with a groove, the hinge 15 is located in the groove, and the front end of the movable top plate 2 is longer than the corresponding position of the groove, so as to ensure the waterproof performance of the whole top.

[0035] In order to prevent the lifting plate 5 from shaking under the influence of wind, a plurality of windproof guide rods 12 are arranged on the side surface of the side plates 1 at the upper end, and a plurality of U-shaped guide rings 13 are arranged on the inner surface of the lifting plate 5, and the U-shaped guide ring 13 is in sliding cooperation with the corresponding windproof guide rod 12.

[0036] The remaining structure is the same as that of example one. Example three

[0037] As shown in Figures 8 to 10As shown, an arc-shaped top drop wind resistance container includes side plates 1, a top plate and a rear door 3, wherein the side plates 1 are high in front and low in back, and the top of the side plates 1 is fixedly connected with upper side beams 4; the overall area of the top plate serves as a movable top plate 2, and the movable top plate 2 is connected with lifting plates 5 through movable top side beams 6 at both sides of the movable top plate 2, and the lifting plates 5 have the same structure as those in Embodiment One or Embodiment Two.

[0038] The front end of the movable top side beam 6 is also provided with a lifting power device 8, and the lifting power device 8 at the front end is fixedly connected with a front vertical column. The remaining structure is the same as that in Embodiment One.

[0039] When the lifting power devices 8 at the front end and the rear end simultaneously act, the overall lifting function of the top of the vehicle compartment is realized, as shown in Figure 10 When the length of the vehicle compartment is too long, the lifting power device 8 can be additionally arranged in the middle vertical column.

[0040] The working process of the arc-shaped top drop wind resistance container of the present application is as follows:

[0041] 1. Loading and unloading goods, and the top plate is in a horizontal state: the lifting power device 8 in the rear vertical column lifts the lifting plate 5 to the normal height of the container, as shown in Figure 2 For the container of Embodiment Three, the lifting power device 8 in the rear vertical column lifts the lifting plate 5 to the normal height of the container, as shown in Figure 9 For the container of Embodiment Three, the lifting power devices 8 in the front and rear vertical columns simultaneously lift the lifting plate 5 to a height higher than the normal height of the container, as shown in Figure 10

[0042] 2. Loading and unloading goods, and the tail of the top plate is higher than the front: the lifting power device 8 in the rear vertical column lifts the lifting plate 5 to a height greater than the normal height of the container, as shown in Figure 11 This facilitates the loading and unloading of goods, and the space on the top of the container can be utilized when loading goods. On the other hand, due to the lifting of the tail, rainwater can flow out from both sides of the vehicle compartment during the loading and unloading of goods in the rain, thereby avoiding the formation of a rain curtain by the rear door, which affects the loading and unloading of goods.

[0043] 3. Full-load transportation: the top plate is in a horizontal state and is equal to the normal height of the container.

[0044] 4. Small amount of goods transportation: the lifting power device 8 in the rear vertical column is lowered, so that the height of the tail of the container is less than the normal height. During the driving of the vehicle, the streamlined shape of the tail reduces wind resistance, thereby reducing the fuel consumption of the vehicle and lowering transportation costs.​
