[0031] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0032] In the description of the present invention, unless otherwise clearly specified and limited, the terms "front" and "rear" refer to the front and rear directions of the vehicle, "lateral" refers to the width direction of the vehicle, and "both sides" refer to both sides of the width direction of the vehicle.

[0033] Embodiment 1

[0034] The vehicle provided in this embodiment includes: a traction mechanism, a traveling mechanism, a frame arranged on the traveling mechanism, and a tank body arranged on the frame.

[0035] See also Figures 1 to 3 Furthermore, the tank body of this embodiment is a horizontal tank body, which includes: a tank body 2 and a wave-breaking member arranged in the tank body 2.

[0036] The tank body 2 includes a circular cylinder and sealing heads disposed at both ends of the cylinder so that a closed space is provided inside the cylinder to contain a liquid medium. The length direction of the tank body 2 is consistent with the front-rear direction of the vehicle, and the tank body 2 has a cross section perpendicular to its length direction.

[0037] The wave-breaking member in this embodiment is arranged along the cross section of the tank body 2, and has two wave-breaking member units 30, which are symmetrically arranged along the longitudinal middle axis of the tank body 2; each wave-breaking member unit 30 is arched, having an arcuate edge 301 and a straight edge 302 connecting the two end points of the arcuate edge 301. The arcuate edge 301 of each wave-breaking member unit 30 is adapted to the inner wall of the tank body 2, and the straight edges 302 of the two wave-breaking member units 30 are opposite and spaced apart.

[0038] The main body of each wave-breaking unit 30 is a film 3 that is unfolded into a bow shape. Furthermore, the wave-breaking unit also includes a supporting structure 4, which is adapted to the contour shape of the film 3 and connected to the edge of the film 3 to form a tension structure to support the film 3 and maintain the shape of the film 3.

[0039] The support structure 4 is made of polytetrafluoroethylene (PTFE), which is also known as the king of plastics. It is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents, thus preventing the liquid medium in the tank body 2 from corroding.

[0040] In actual use, the support structure 4 may also be made of other hard corrosion-resistant plastics; or, the support structure 4 may also be made of metal materials.

[0041] In this embodiment, the support structure 4 includes: a support edge 401 and a support edge 402, wherein the support edge 401 is arranged along the arc edge 301, and the support edge 402 is arranged along the straight edge 302. The support edge 401 and the support edge 402 both have a U-shaped opening, and the edge of the film 3 is clamped or bonded in the U-shaped opening. Figure 2 shown.

[0042] In actual use, the supporting edge 401 may also include two separable parts, and the edge of the film 3 is sandwiched between the two parts and adhered to each other by glue, which is not limited here.

[0043] When the wave-proof member of this embodiment is placed in the tank body 2, the supporting edge 401 of the supporting structure 4 is connected to the inner wall of the tank body 2. Figure 3As shown, the inner wall of the tank body 2 and the arcuate edge 301 corresponding to each wave-breaking unit 30 are provided with a support 5, and the support 5 is extended along the inner wall of the tank body 2. Specifically, the support 5 is in the shape of an arc plate, which has an outer side facing the inner wall of the tank body 2 and an inner side facing the inside of the tank body 2, wherein the outer side is fixedly connected to the inner wall of the tank body 2, and the inner side constitutes a mounting portion to be connected to the wave-breaking member. The mounting portions of the support edge 401 support 5 are all provided with mounting holes, and the wave-breaking unit 30 and the tank body 2 are fixedly connected to each other by inserting bolts 61.

[0044] In actual use, the wave-breaking unit 30 and the tank body 2 may also be connected by other connecting parts besides the bolts 61 .

[0045] In this embodiment, the wave-proof component uses a non-metallic film 3 as its main body, and utilizes the flexibility of the film 3 itself to absorb the liquid surge force of the liquid in the tank body 2.

[0046] Preferably, the film 3 of the present embodiment is made of ethylene-tetrafluoroethylene copolymer (ETFE), which is the toughest fluoroplastic. While maintaining the good heat resistance, chemical resistance and electrical insulation properties of PTFE, the radiation resistance and mechanical properties are also greatly improved. The tensile strength can reach 50MPa, which is nearly twice that of polytetrafluoroethylene. This makes ethylene-tetrafluoroethylene copolymer (ETFE) tough and corrosion-resistant. The strong toughness can offset the impact force caused by the liquid surge in the tank body 2 and effectively avoid damage caused by corrosion of the liquid medium.

[0047] In other feasible solutions, the film 3 may also be made of polyvinyl chloride (PVC), polyethylene (PE), polytetrafluoroethylene (PTFE) or polyvinylidene fluoride (PVDF).

[0048] Polyvinyl chloride (PVC) has good mechanical properties, tensile strength of about 60MPa, impact strength of 5kJ / m2~10kJ / m2. Polyethylene (PE) Polyethylene (PE) has excellent low temperature resistance (the lowest operating temperature can reach -100℃~-70℃), good chemical stability, and can withstand the corrosion of most acids and alkalis (not resistant to acids with oxidizing properties). Polytetrafluoroethylene (PTFE) has the characteristics of acid and alkali resistance and resistance to various organic solvents. It is almost insoluble in all solvents to prevent corrosion by the liquid medium in the tank body 2. Polyvinylidene fluoride (PVDF) has excellent chemical corrosion resistance, excellent high temperature color change resistance and oxidation resistance, as well as excellent wear resistance, flexibility, high swelling strength and impact resistance.

[0049] Therefore, polyvinyl chloride (PVC), polyethylene (PE), polytetrafluoroethylene (PTFE) or polyvinylidene fluoride (PVDF) can be used as a film instead of ethylene tetrafluoroethylene copolymer (ETFE).

[0050] In actual use, the film 3 can also be made of other materials that have toughness and corrosion resistance and can be used as wave-breaking parts for movable containers such as tanks, which is not limited here.

[0051] In other feasible solutions, the film 3 may also be made of a fabric membrane material, which is composed of a high-strength fabric substrate and a polymer coating, and has sealing properties while also providing appropriate mechanical support to withstand stronger liquid surge impact.

[0052] In other feasible solutions, the film 3 may also be an inflatable film, which includes a double-layer film 3 with a closed space between the two layers of film 3 to be filled with gas so that the film 3 forms a tension structure; preferably, the filling gas is nitrogen.

[0053] The wave-breaking member of the present embodiment is arranged along the cross section and partially closes the cross section of the tank body 2, approximately closing 30% of the cross-sectional area. In other feasible schemes, the wave-breaking member can also be arranged obliquely in the length direction of the tank body 2 to actually increase the layout area of ​​the wave-breaking member in the tank body 2, and effectively reduce the impact force of the liquid medium caused by the liquid surge. Furthermore, the angle between the wave-breaking member and the cross section of the tank body 2 is not greater than 70°, so that the area of ​​the film 3 projected on the cross section of the tank body 2 accounts for more than 20% of the cross-sectional area. For example: the layout area of ​​the wave-breaking member of the present embodiment along the cross section can also be appropriately reduced, and a notch can be provided at the arc-shaped edge 301 of each wave-breaking member unit 30, so that the arc-shaped edge 301 does not completely match the inner wall of the tank body 2, but has a gap with the inner wall.

[0054] In other feasible solutions, the wave-breaking member can also completely close the cross-section of the tank body 2 to divide the internal space of the tank body 2 into unconnected sub-spaces, which can independently contain the same or different liquid media and also play a role in reducing the impact force of liquid surges.

[0055] In other feasible schemes, the wave-breaking parts also include: a metal wave-breaking plate, which is combined with the film 3 to partially or completely close the cross-section; the metal wave-breaking plate and the film can be combined in a connected manner in the tank body or in an interval arrangement.

[0056] In other feasible solutions, there may be one, two or more wave-breaking members along the length direction of the tank body 2, and the wave-breaking members are arranged at intervals along the length direction of the tank body 2.

[0060] Specifically, the film 3 of this embodiment is circular, and the support structure 4 is a circular ring, which surrounds the circumference of the film 3. The support structure 4 is provided with a plurality of spaced connection holes, each of which corresponds to a support 5.

[0061] The connecting piece of the present embodiment is a clamping ring 62 , which respectively corresponds to the connecting hole penetrated through the supporting structure 4 and the through hole of the support 5 , so as to realize the fixed installation of the wave-breaking piece on the inner wall of the tank body 2 .

[0062] Embodiment 3

[0063] like Figure 5 As shown, the vehicle and its tank body of this embodiment are substantially the same in structure as those of the second embodiment, except for the shape of the wave-breaking member.

[0064] In this embodiment, the wave-breaking member is arranged along the upper part of the tank body 2 and extends downward to the middle part. The film 3 of the wave-breaking member is roughly arched, including an arc-shaped edge 304 that arches upward at the upper part and a straight edge 305 at the lower part. The arc-shaped edge 304 is larger than a semicircle. The supporting structure 4 includes an arc-shaped supporting edge 404 and a straight supporting edge 405 connected to both ends thereof; wherein the supporting edge 405 is columnar, and the film 3 is wrapped around it and fixed by adhesion, such as Figure 6 shown.

[0065] It should be noted that the wave-breaking member of this embodiment is fixed to the inner wall of the tank body 2 only at its arc-shaped edge 304 .

[0066] Embodiment 4

[0067] like Figure 7 As shown, the vehicle and its tank body of this embodiment are substantially the same in structure as those of the second embodiment, except for the shape of the wave-breaking member.

[0068] Figure 7 It is a schematic diagram of the structure in which the wave-breaking member of this embodiment is arranged inside the tank body 2, wherein the connection structure of the wave-breaking member corresponding to the inner wall in the width direction of the tank body 2 is omitted.

[0069] In this embodiment, the wave-proof member is only arranged in the middle of the height direction of the tank body 2. The film 3 of the wave-proof member has two upper and lower straight edges 306, and two arc-shaped edges located in the width direction of the tank body 2. Among them, the supporting edge 406 of the supporting structure 4 corresponding to the two straight edges 306 is a column, and the film 3 is wrapped around it and fixed by adhesion, such as Figure 6 shown.

[0070] It should be noted that the wave-proof member of this embodiment is fixed to the inner wall of the tank body 2 only at its arc-shaped edge ( Figure 7 (omitted in the figure).

[0071] Furthermore, the wave-breaking piece can also be composed of two upper and lower films 3 spliced ​​together, and the adjacent edges of the two films 3 are also horizontal straight edges, and both are provided with columnar supporting edges 407, and the films 3 are also wrapped thereon and fixed by adhesion (only one supporting edge 407 is shown in the figure).

[0072] Embodiment 5

[0073] like Figure 8 As shown, the vehicle and its tank body of this embodiment are substantially the same in structure as those of the second embodiment, except that the wave-breaking member further comprises: a plurality of reinforcing frames for supporting the film 3, each reinforcing frame being arranged along the surface on which the film 3 is arranged.

[0074] Figure 8 It is a schematic diagram of the structure in which the wave-breaking member of this embodiment is arranged in the tank body, wherein the connection structure between the outer edge of the film 3 and the inner wall of the tank body 2 is omitted.

[0075] Specifically, the reinforcement frame of this embodiment includes: a strip reinforcement frame 71 and a polygon reinforcement frame 72; multiple strip reinforcement frames 71 are arranged crosswise through the center of the cross section of the tank body 2, and there are two polygon reinforcement frames 72, which are arranged concentrically with the center of the cross section of the tank body 2. Each reinforcement frame is connected to the surface of the film 3 by adhesion, binding or wrapping.

[0076] In actual use, either the strip reinforcement frame 71 or the polygon reinforcement frame 72 can be omitted; the structure of the reinforcement frame is not limited to the shape in this embodiment, and can also be circular, etc.

[0077] It should be noted that the arrangement shape of the film body in the tank body of the present invention is not limited to the shapes listed in the above embodiments, and can be changed according to actual needs. At the same time, when part of the edge of the film body does not need to be connected to the inner wall of the tank body, the connecting piece of the edge can be omitted.

[0078] The film-type wave-breaking plate in the tank body of the present invention mainly adopts a film as the main structure, and the film is flexible and can absorb the liquid surge force of the liquid, avoiding the related failure risk. In addition, it is corrosion-resistant and easy to repair, solving the industry problems of fatigue cracking, instability, corrosion, deformation, etc. of the wave-breaking plate in the prior art. At the same time, it is light in weight, greatly reducing the overall weight of the tank container and reducing operating costs.
