Description

Technical Field

[0001] The utility model relates to the technical field of tanker transportation, in particular to a safety transportation device for a hazardous chemical tanker. Background Art

[0002] A hazardous chemical tanker is a heavy-duty vehicle specially used to transport liquid chemicals. Its core feature is a sealed tank body made of metal. In order to reduce the impact of the liquid on the tank body during transportation, several wave-breaking plates are installed in the tank body. These wave-breaking plates divide the inner cavity of the tank body into multiple compartments, aiming to reduce the risk of damage to the tank body and improve the safety of people around the tank body during transportation.

[0003] Early wave-breaking plates usually adopted an assembled structure, such as the fixed structure of a wave-breaking plate for a liquid tank truck with application number CN202222164860.1. This structure welds some connecting parts inside the tank body and fixes the wave-breaking plate to the connecting parts with bolts. However, long-term use has found that this bolt connection method is prone to breakage at the connection position, and the connection strength is insufficient, and maintenance is also relatively inconvenient.

[0004] In response to the above problems, an integrated welded structure later emerged, such as a new type of welded wave-breaking plate structure for tank vehicles with application number CN202322353027.6. In this structure, the wave-breaking plate matches the cross-sectional shape of the tank body and is connected to the inner wall of the tank body by welding. Although this design enhances the connection strength between the wave-breaking plate and the tank body, since the entire circle is welded to the inner wall of the tank body, this inevitably increases the overall weight of the tank body. Utility Model Content

[0005] In order to solve the technical problem in the above-mentioned background technology that the existing wave-breaking plate that matches the cross-sectional shape of the tank body is welded to the inner wall of the tank body in the entire circle, which increases the overall weight of the tank body, the utility model provides a hazardous chemical tank truck safety transportation device.

[0006] The technical solution of this utility model is as follows:

[0007] A hazardous chemical tanker safe transportation device includes a tank body, and several groups of wave-breaking structures are arranged at intervals inside the tank body along its length direction. The wave-breaking structures include two first wave-breaking plates and a second wave-breaking plate behind the two first wave-breaking plates. The two first wave-breaking plates are arranged relatively spaced apart along the width direction of the tank body, and the sides facing away from each other are connected to the inner walls on both sides of the width of the tank body. The second wave-breaking plate is located in the middle of the tank body, and the upper and lower sides are connected to the inner walls on both sides of the height of the tank body. The above structural design changes the traditional full-circle continuously welded wave-breaking plates into a segmented type, that is, each group of wave-breaking structures is only arranged at key positions of the tank body, reducing the amount of material used. This design not only reduces the overall weight of the tank body and avoids unnecessary material waste, but also maintains sufficient wave-breaking effect.

[0008] As a preferred implementation, the projection shape of the two first wave-breaking plates and the second wave-breaking plates along the length direction of the tank body is an ellipse that matches the cross-sectional shape of the tank body to ensure sufficient wave-breaking effect.

[0009] Furthermore, the first wave-breaking plate includes a first curved plate that cooperates with and is connected to the inner wall of the tank body. A first plate body is provided on the inner side of the first curved plate, and the width of the first curved plate along the length direction of the tank body is greater than the thickness of the first plate body, so as to ensure the connection strength between the first wave-breaking plate and the tank body while avoiding unnecessary material waste.

[0010] In order to improve the connection strength between the first wave-breaking plate and the tank body, a triangular first reinforcing rib connected to the first arc-shaped plate is laterally provided on the first plate body, and the first reinforcing rib is matched and connected to the inner wall of the tank body on the side away from the first plate body.

[0011] Furthermore, the second wave-breaking plate includes a second plate body arranged vertically, and second curved plates are respectively provided on the upper and lower sides of the second plate body to cooperate with the inner wall of the tank body. The width of the second curved plate is greater than the thickness of the second plate body to ensure the connection strength between the second wave-breaking plate and the tank body while avoiding unnecessary material waste.

[0012] To ensure that the first wave-breaking plate and the second wave-breaking plate have sufficient wave-resistant strength, the sum of the areas of the two first plates is not less than 70% of the cross-sectional area of ​​the tank body, and the area of ​​the second plate is not less than 70% of the cross-sectional area of ​​the tank body.

[0013] In order to further improve the strength of the first wave-breaking plate and the second wave-breaking plate, the first plate body and the second plate body are respectively located in the middle of the first curved plate and the second curved plate.

[0014] Furthermore, second reinforcing ribs are vertically provided on both side surfaces of the second plate body, and the upper and lower ends of the second reinforcing ribs are respectively connected to the two second arc-shaped plates.

[0015] In the hazardous chemicals tanker safety transportation device described above, the spacing between the two first plates is not less than 60 cm, making it easy for people to pass between the two first plates. As a result, no additional manholes need to be opened on the first plate and the second plate for people to pass through, saving processing costs.

[0016] The utility model is a safe transportation device for hazardous chemical tankers. The traditional full-circle continuously welded wave-breaking plates are designed to be segmented, that is, each group of wave-breaking structures is only set at the key position of the tank body, reducing the amount of material used. This design not only reduces the overall weight of the tank body and avoids unnecessary material waste, but also maintains sufficient wave-breaking effect. BRIEF DESCRIPTION OF THE DRAWINGS

The two first wave-breaking plates 21 are arranged at relative intervals along the width direction of the tank body 1, and the sides opposite to each other are connected to the inner walls on both sides of the width of the tank body 1. The second wave-breaking plate 22 is located in the middle of the tank body 1, and the upper and lower sides are connected to the inner walls on both sides of the height of the tank body 1. The above structural design changes the traditional full-circle continuously welded wave-breaking plates into a segmented type, that is, each group of wave-breaking structures 2 is only set at the key position of the tank body 1, reducing the amount of material used. This design not only reduces the overall weight of the tank body 1 and avoids unnecessary material waste, but also maintains sufficient wave-breaking effect.

[0027] Combine Figure 4 The projection shape of the two first wave-breaking plates 21 and the second wave-breaking plates 22 along the length direction of the tank body 1 is an ellipse that matches the cross-sectional shape of the tank body 1 to ensure sufficient wave-breaking effect.

[0028] Combine Figure 2 The first wave-breaking plate 21 includes a first curved plate 212 that cooperates with and is welded to the inner wall of the tank body 1. A first plate body 211 is provided on the inner side of the first curved plate 212, and the width of the first curved plate 212 along the length direction of the tank body 1 is greater than the thickness of the first plate body 211, so as to ensure the connection strength between the first wave-breaking plate 21 and the tank body 1 while avoiding unnecessary material waste. In order to ensure that the first wave-breaking plate 21 has sufficient wave-resistant strength, the sum of the areas of the two first plates 211 is not less than 70% of the cross-sectional area of ​​the tank body 1.

[0029] The first curved plate 212 and the first plate body 211 include but are not limited to being integrally manufactured or welded, and a triangular first reinforcing rib 213 connected to the first curved plate 212 is horizontally provided on the first plate body 211, and the first reinforcing rib 213 is matched with and welded to the inner wall of the tank body 1 on the side facing away from the first plate body 211, and to facilitate processing and ensure connection strength, the first reinforcing rib 213 is welded to the first curved plate 212 and the first plate body 211.

[0030] Combine Figure 3 The second wave-breaking plate 22 includes a second plate body 221 arranged vertically, and the upper and lower sides of the second plate body 221 are respectively provided with second curved plates 222 that are connected to the inner wall of the tank body 1. The width of the second curved plate 222 is greater than the thickness of the second plate body 221, so as to ensure the connection strength between the second wave-breaking plate 22 and the tank body 1 while avoiding unnecessary material waste.

It can be understood that the spacing between adjacent first plates 211 and second plates 221 in the length direction of the tank body 1 is also not less than 60 cm, and thus there is no need to open additional manholes on the first plate 211 and the second plate 221 for people to pass through, saving processing costs.
