[0008] In this embodiment, the wave-breaking plates are in a frustum shape, and the cross-sectional area of ​​the wave-breaking plates decreases in the direction in which the two wave-breaking plates face each other.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0033] In related technologies, liquid tanks are generally used to store liquid substances. They consist of a tank body and a wave-breaking plate. The tank body defines a chamber for containing the liquid. The wave-breaking plate is housed within the tank body to stop the liquid, thereby reducing fluctuations and impacts of the liquid medium and improving the safety and reliability of the tank. The wave-breaking plate divides the liquid in the chamber into two parts, allowing fluid flow between the two parts.

[0034] In the related art, the wave-breaking plate is a single-piece structure, which has poor impact resistance and low structural strength, making the wave-breaking plate easily damaged and causing safety hazards during the transportation of the liquid tank.

[0035] For ease of understanding and description, the state of the liquid tank when in use is used as a reference, and the up and down directions of the liquid tank are used as the up and down directions below.

[0036] Figure 1 It is a structural schematic diagram of the wave-proof device of the present invention. Figure 2 yes Figure 1 A magnified view of the structure at point A in the middle. Figure 3 yes Figure 1 A structural schematic diagram of another perspective of the structure shown in .

[0037] See Figures 1 to 3The application provides a wave-preventing device which is accommodated in a tank body, the wave-preventing device comprising: two wave-preventing plates 100 and a plurality of communication structures 200; the two wave-preventing plates 100 are arranged along the axial direction of the tank body at intervals, and the outer periphery of the wave-preventing plate 100 is sealingly connected with the inner circumferential wall of the tank body; the plurality of communication structures 200 are arranged along the up-down direction at intervals, each communication structure 200 extends along the axial direction of the tank body, and the communication structure 200 is provided through and sealingly connected with the two wave-preventing plates 100; a communication passage is arranged in the communication structure 200, and is used for the flow of a liquid substance in the tank body; and the two wave-preventing plates 100, the plurality of communication structures 200 and the tank body form a sealed cavity 500.

[0038] The wave-preventing device divides the liquid substance in the accommodation cavity into at least two parts. When the liquid tank transports the liquid substance, the liquid substance can impact on the wave-preventing device respectively, so as to reduce the influence of the overall liquid substance on the transport vehicle under the action of inertial force, and ensure the safety and stability during the transportation of the liquid tank.

[0039] On the one hand, the wave-preventing device is formed by the combination of a plurality of plates to form a three-dimensional structure, so as to effectively improve the structural strength and impact resistance of the wave-preventing device. In addition, the contact area between the wave-preventing device and the tank body is also increased, so that the impact load and pressure load borne by the wave-preventing device can be uniformly conducted to the tank body, and the stability and reliability of the wave-preventing device are effectively improved.

[0040] On the other hand, the sealed cavity 500 formed between the wave-preventing device and the tank body can support the wave-preventing device, so as to further improve the structural strength and impact resistance of the wave-preventing device, so that the impact load on the wave-preventing device can be fully decomposed and conducted.

[0041] In addition, when the wave-preventing plate 100 is impacted, part of the impact kinetic energy can be conducted to the gas in the sealed cavity 500, so that the flow direction, pressure and other parameters of the gas in the sealed cavity change, so that the impact kinetic energy of the liquid substance is dispersed in the time and space dimensions, and the energy redistribution and dissipation of the impact kinetic energy are realized in cooperation with the impact spectrum characteristics, so as to avoid the buckling instability of the wave-preventing plate 100 caused by the impact load.

[0042] Figure 4 It is a structural schematic view of the wave-preventing plate of the application. Figure 5 It is Figure 4 It is a structural schematic view of another view of the structure shown in the figure.

[0043] Referring to Figures 1 to 5 In the embodiment, the wave-preventing device comprises two wave-preventing plates 100. The wave-preventing plate 100 is in the shape of a truncated cone, and the cross-sectional area of the wave-preventing plate 100 gradually decreases in the opposite direction of the two wave-preventing plates 100.

[0044] Each wave-breaking plate 100 includes a facing end facing the other wave-breaking plate 100 and an opposite end facing away from the other wave-breaking plate 100. The facing ends of the two wave-breaking plates 100 are connected to each other to support the two wave-breaking plates 100 and enhance the structural strength of the wave-breaking device. The opposite ends of the wave-breaking plates 100 are sealed to the inner circumferential wall of the tank to confine the wave-breaking device within the tank.

[0045] When the liquid material impacts the wave-breaking plate 100, the liquid material flows on the wave-breaking plate 100 from the opposite ends toward the opposite ends of the wave-breaking plate 100 and impacts each other at the opposite ends of the wave-breaking plate 100 to reduce the impact kinetic energy of the liquid material and ensure the reliability and stability of the wave-breaking device.

[0046] See Figure 1 、 Figures 3 to 5 In this embodiment, the centers of both ends of the wave-breaking plate 100 lie on the tank's axis. That is, the centers of the opposing ends and the centers of the facing ends of the wave-breaking plate 100 lie on the tank's axis. When liquid material impacts the wave-breaking plate 100, it converges at its center. This allows the wave-breaking plate 100 to evenly distribute the impact load and transfer it to the tank, ensuring the stability and reliability of the wave-breaking device.

[0047] In some embodiments, in a projection plane perpendicular to the axial direction of the tank body, the end surface projection of the opposite end of the wave-breaking plate 100 is circular, so that the wave-breaking plate 100 fits tightly against the tank body, effectively improving the connection strength and load conduction performance between the wave-breaking plate 100 and the tank body.

[0048] In other embodiments, in a projection plane perpendicular to the axial direction of the tank body, the projections of the end faces of the wave-breaking plate 100 facing each other may be in the shape of a circle, a regular polygon, or the like.

[0049] In some embodiments, the wave-breaking plate 100 is in a truncated cone shape.

[0050] See Figure 1 、 Figures 3 to 5 In this embodiment, in the cross-section where the axis of the tank body is located, the extension track between the opposite ends and the opposite ends of the wave-breaking plate 100 is set in an arc shape to further improve the structural strength and impact resistance of the wave-breaking plate 100.

[0051] In some embodiments, within the cross-section of the tank body axis, the curvature of the extension trajectory of the wave-breaking plate 100 gradually increases from the facing ends toward the opposite ends, so that the opposite ends of the wave-breaking plate 100 are bent to form a transition portion 111. The extension curve of the transition portion 111 is approximately parallel to the axial direction of the tank body, thereby facilitating full contact and connection between the transition portion 111 and the tank body, effectively improving the connection strength and load transfer performance between the wave-breaking plate 100 and the tank body.

[0052] See Figures 1 to 5 In this embodiment, a first communication hole 101 and a second communication hole 102 are respectively formed in the upper and lower portions of the wave-breaking plates 100. The first communication holes 101 of the two wave-breaking plates 100 are arranged opposite each other to accommodate a communication structure 200 and are sealed with the communication structure 200. The second communication holes 102 of the two wave-breaking plates 100 are arranged opposite each other to accommodate a communication structure 200 and are sealed with the communication structure 200.

[0053] In some embodiments, the first connecting hole 101 is located at the upper part of the wave-breaking plate 100 and is open upward, so that the connecting structure 200 in the first connecting hole 101 and the peripheral side wall of the tank body can enclose to form a first conducting channel 211 for the circulation of gaseous and liquid substances.

[0054] When the tank is filled with or transporting liquid, the first conductive channel 211 facilitates the flow of liquid at the top of the tank, allowing the liquid level to rise to the top of the tank, thereby increasing the tank's capacity. Furthermore, the first conductive channel 211 facilitates the flow of gas at the top of the tank, preventing damage to the tank due to excessive pressure at the top of the tank when storing cryogenic or high-pressure liquids.

[0055] In other embodiments, the first communication hole 101 is located on the top of the wave-breaking plate 100 .

[0056] In some embodiments, the first communication hole 101 is fan-shaped, so that the load carried by the wave-breaking plate 100 can be evenly transferred to the flow structure, thereby effectively improving the load-bearing capacity of the wave-breaking device.

[0057] In some embodiments, there may be a plurality of first communicating holes 101 , and the plurality of first communicating holes 101 are spaced apart around the circumference of the wave-breaking plate 100 .

[0058] See Figures 1 to 5 In this embodiment, the second connecting hole 102 is located at the bottom of the wave-breaking plate 100 and opens downward, so that the connecting structure 200 in the second connecting hole 102 and the inner wall of the tank body together form a second conducting channel 221 for circulating gaseous and liquid substances.

[0059] When the tank is unloading liquid, the liquid material at the bottom of the tank can be discharged to the outside through the second conducting channel 221, avoiding the wave-proof device blocking the flow of the liquid material at the bottom of the tank, preventing the liquid material from remaining in the tank, and improving the emptying capacity of the liquid tank.

[0060] In some embodiments, the hole shape of the second connecting hole 102 is fan-shaped. On the one hand, it avoids stress concentration on the second connecting hole 102 and ensures the load-bearing capacity of the wave-breaking plate 100. On the other hand, it facilitates the uniform transfer of the load borne by the wave-breaking plate 100 to the flow structure, thereby effectively improving the load-bearing capacity of the wave-breaking device.

[0061] In other embodiments, there may be multiple second connecting holes 102, and the multiple second connecting holes 102 may be arranged at circumferential intervals around the wave-breaking plate 100, but at least one second connecting hole 102 is located at the bottom of the wave-breaking plate 100, and the other second connecting holes 102 may be located at the lower part of the wave-breaking plate 100.

[0062] See Figure 1 、 Figures 2 to 5 In this embodiment, the wave-breaking plate 100 further includes a third communication hole 103, spaced from the outer wall of the wave-breaking plate 100. A communication structure 200 is housed within the third communication hole 103, which defines a third conductive channel 231. This facilitates the passage of liquid material through the wave-breaking device. This reduces the impact force of the liquid material on the wave-breaking device. Furthermore, after flowing through the wave-breaking device, some liquid material impacts other liquid material, thereby reducing the kinetic energy of the liquid material and ensuring the safety and reliability of the liquid tank.

[0063] In some embodiments, the third connecting hole 103 is located on the end surface of the opposite end of the wave-breaking plate 100, so that the liquid material can be input into the third conductive channel 231 after converging at the opposite end of the wave-breaking plate 100, thereby allowing the liquid material to fully reduce the impact kinetic energy of the liquid material when converging and flowing into the third conductive channel 231.

[0064] In some embodiments, the wave-breaking plate 100 has a connecting portion 112 protruding from the third connecting hole 103, and the connecting portion 112 extends along the circumference of the third connecting hole 103 for fitting and sealingly connecting to the end of the connecting structure 200, thereby improving the connection strength and structural stability between the wave-breaking plate 100 and the connecting structure 200.

[0065] In other embodiments, the connection portion 112 is located on the end surface of the opposing ends of the wave-breaking plate 100 and extends toward the other wave-breaking plate 100 to prevent the connection portion 112 from extending away from the other wave-breaking plate 100 and affecting the flow of liquid material into the third conductive channel 231. After a portion of the liquid material gathers at the opposing ends of the wave-breaking plate 100, it passes through the wave-breaking device through the third conductive channel 231 to impact the remaining portion of the liquid material at the other end of the wave-breaking device, thereby fully reducing the kinetic energy of the liquid material.

[0066] See Figure 1 、 Figures 2 to 5In this embodiment, in a plane perpendicular to the axis of the tank body, the axis of the third connecting hole 103 coincides with the axis of the wave-breaking plate 100, so that the third connecting hole 103 is located in the middle of the wave-breaking plate 100, thereby facilitating the even transmission of the impact load and pressure load of the liquid substance on the middle of the wave-breaking device to the tank body through the two wave-breaking plates 100, thereby ensuring the stability and reliability of the wave-breaking device.

[0067] In some embodiments, in a plane perpendicular to the axis of the tank body, the radius of the third connecting hole 103 is approximately 1 / 3 of the radius of the wave-breaking plate 100, so as to maximize the circulation efficiency of the liquid substance while ensuring the impact resistance of the wave-breaking device.

[0068] In some embodiments, the third communication hole 103 is circular.

[0069] In some embodiments, there may be a plurality of third communicating holes 103 , and the plurality of third communicating holes 103 may be spaced apart on the wave-breaking plate 100 . In other embodiments, the axis of the third communicating hole 103 is parallel to the axis of the wave-breaking plate 100 .

[0070] Figure 6 It is a structural schematic diagram of the first circulation plate of the present invention. Figure 7 yes Figure 6 A structural schematic diagram of another perspective of the structure shown in .

[0071] See Figures 1 to 3 、 Figure 6 、 Figure 7 In this embodiment, the communication structure 200 includes a first flow plate 210 and a second flow plate 220. The first flow plate 210 is located above the wave-breaking plate 100. The first flow plate 210 extends axially along the tank body and is adapted to fit within the first communication holes 101 of the wave-breaking plates 100. The outer periphery of the first flow plate 210 is in contact with and sealingly connected to the inner circumferential walls of the first communication holes 101 of the two wave-breaking plates 100, thereby enclosing the first flow plate 210 with the inner circumferential wall of the tank body top to form a first conductive channel 211.

[0072] In some embodiments, the first circulation plate 210 is arc-shaped in a plane perpendicular to the axial direction of the tank body. This allows a portion of the impact load and pressure load borne by the wave-breaking plate 100 to be transferred to the first circulation plate 210 and then to the tank body through the first circulation plate 210, effectively improving the connection strength and reliability between the two wave-breaking plates 100 and the first circulation plate 210. In a plane perpendicular to the axial direction of the tank body, the two sides of the first circulation plate 210 are bent toward each other to form two bent portions 212. The two bent portions 212 are sealed to the inner circumferential wall of the tank body, thereby increasing the connection area between the first circulation plate 210 and the tank body, thereby effectively ensuring the structural strength and load-bearing capacity of the wave-breaking device.

[0073] In other embodiments, in a plane perpendicular to the axis of the tank, the first flow plate 210 is in a fan-shaped structure with a central angle greater than 180°.

[0074] In other embodiments, the length of the first flow plate 210 along the tank axis gradually decreases in the direction toward the tank axis to adapt to the gradually changing spacing between the two wave-breaking plates 100, thereby reducing the production cost of the wave-breaking device.

[0075] See Figures 1 to 3 、 Figure 6 、 Figure 7 In this embodiment, the second circulation plate 220 is located at the lower part of the wave-breaking plate 100. The second circulation plate 220 is used to enclose the inner peripheral wall of the bottom of the tank body to form a second conductive channel 221 so that the liquid material in the tank body can be discharged through the second conductive channel 221.

[0076] In some embodiments, the structure of the second circulation plate 220 refers to the structure of the first circulation plate 210. The second circulation plate 220 and the first circulation plate 210 are arranged in a mirror-symmetrical manner around the axis of the tank.

[0077] In some embodiments, the communication structure 200 further includes a flow tube 230. The flow tube 230 is spaced apart from the outer circumferential wall of the wave-breaking plate 100 in the radial direction of the tank body. The flow tube 230 is housed within the third communication hole 103, conforming to and sealingly connected to the inner circumferential wall of the third communication hole 103. The flow tube 230 is open at both ends and hollow inside to form a third conductive channel 231 for the flow of gaseous and liquid substances.

[0078] In some embodiments, both ends of the flow tube 230 are respectively attached to and sealed against the connection portions 112 of the two wave-breaking plates 100 , thereby effectively ensuring the connection strength and reliability between the flow tube 230 and the two wave-breaking plates 100 .

[0079] In other embodiments, in the axial direction of the tank, both ends of the flow tube 230 are located between the two wave-breaking plates 100 and do not exceed the connecting portion 112 , thereby preventing the ends of the flow tube 230 from blocking the liquid from flowing into the flow tube 230 .

[0080] Figure 8 It is a structural schematic diagram of the first pad of the present invention.

[0081] See Figures 1 to 3 、 Figure 6 、 Figure 8 In this embodiment, the wave-proof device further includes two first pads 310 and two second pads 320. The first pads 310 and the second pads 320 extend along the inner circumferential wall of the tank body to fit tightly on the tank body.

[0082] The two first pads 310 are respectively arranged corresponding to the two bent portions 212 of the first circulation plate 210, so that the first pads 310 are sealed and connected to the tank body, the two wave-breaking plates 100, and one of the bent portions 212 of the first circulation plate 210, thereby improving the connection strength and sealing performance between the two wave-breaking plates 100, the first circulation plate 210 and the tank body, avoiding excessive load borne by the wave-breaking plates 100, which may cause gaps between the first circulation plate 210 and the tank body, and preventing liquid substances from seeping into the sealed cavity 500, thereby effectively ensuring the structural strength and stability of the wave-releasing device.

[0083] In some embodiments, the first backing plate 310 includes an extension portion 311 and two retaining portions 312. The extension portion 311 extends axially along the tank body to pass over the opposite ends of the two wave-breaking plates 100. The extension portion 311 is tightly fitted to the inner circumferential walls of the first communication holes 101 of the two wave-breaking plates 100. The two retaining portions 312 are respectively disposed at both ends of the extension portion 311 and are capable of extending circumferentially along the wave-breaking plates 100. The facing end walls of the two retaining portions 312 are tightly fitted to the transition portion 111 of the wave-breaking plates 100 to improve the connection strength between the wave-breaking plates 100 and the tank body.

[0084] In other embodiments, the bent portion 212 of the first circulation plate 210 is pressed against the connection between the transition portion 111 and the first pad 310, and the bent portion 212 and the tank body are respectively located on opposite sides of the first pad 310, so as to increase the contact area between the first pad 310, the transition portion 111, the bent portion 212 and the tank body, thereby effectively improving the structural strength and impact resistance of the wave-proof device and ensuring the sealing performance between the wave-proof device and the tank body.

[0085] In other embodiments, the bent portion 212 of the first circulation plate 210 is arranged parallel to the first pad 310 so that the bent portion 212 and the extension portion 311 are fully fitted together, thereby effectively improving the sealing performance between the first circulation plate 210 and the tank body and preventing liquid substances from seeping into the sealed cavity 500 through the gap between the first circulation plate 210 and the tank body.

[0086] See Figures 1 to 3 、 Figure 6 、 Figure 8 In this embodiment, the two first gaskets 310 are located at the two bends 212 of the first circulation plate 210, thereby enhancing the connection strength between the first circulation plate 210 and the tank body and ensuring the sealing performance between the first circulation plate 210 and the tank body. Furthermore, the two first gaskets 310 are spaced apart circumferentially around the wave-breaking plate 100 to facilitate the flow of liquid through the space between the two first gaskets 310, thereby effectively improving the emptying performance of the tank body.

[0087] See Figures 1 to 3 、 Figure 6 、 Figure 8In this embodiment, the second pad 320 is sealed to the tank body, the two wave-breaking plates 100 and the second circulation plate 220 to effectively improve the structural strength and sealing performance between the second circulation plate 220 and the tank body.

[0088] In some embodiments, the structure of the second circulation plate 220 refers to the structure of the first circulation plate 210. The connection between the second gasket 320, the second circulation plate 220, the wave-breaking plate 100, and the tank body refers to the connection between the first gasket 310, the first circulation plate 210, the wave-breaking plate 100, and the tank body.

[0089] In other embodiments, the second pad 320 and the first pad 310 are mirror-symmetrical about the axis of the wave-breaking board 100 .

[0090] Figure 9 It is a structural schematic diagram of the support structure of the present invention.

[0091] See Figure 1 、 Figure 3 、 Figure 5 、 Figure 9 In this embodiment, the wave-breaking structure also includes a supporting structure 400, which is located in the sealed cavity 500. The supporting structure 400 extends along the axial direction of the tank body to connect the two wave-breaking plates 100, thereby supporting the two wave-breaking plates 100 and improving the structural strength and impact resistance of the wave-breaking device.

[0092] See Figure 1 、 Figure 3 、 Figure 5 、 Figure 9 In this embodiment, the support structure 400 includes two third pads 420 and a support rod 410. The two third pads 420 are respectively attached to the two wave-breaking plates 100. The two ends of the support rod 410 are respectively connected to and support the two third pads 420.

[0093] The third pad 420 is attached to the wave-breaking plate 100 to increase the contact area between the supporting structure 400 and the wave-breaking plate 100, thereby preventing damage to the connection between the wave-breaking plate 100 and the supporting structure 400 due to excessive local stress when the wave-breaking plate 100 is under load, thereby ensuring the structural strength and reliability of the wave-breaking device.

[0094] In some embodiments, the third pad 420 is circular, so that the support rod 410 can evenly transfer the load on the wave-breaking plate 100 to another wave-breaking plate 100 through the third pad 420 .

[0095] In some embodiments, in a plane perpendicular to the axial direction of the tank body, the support rod 410 is located at the center of the third pad 420 to facilitate load transmission and distribution between the third pad 420 and the support rod 410 .

[0096] In some embodiments, the support rod 410 may be a cylindrical structure to reduce the weight of the wave-breaking device.

[0097] See Figure 1 、 Figure 3 、 Figure 5 、 Figure 9 In this embodiment, the wave-proof device includes a plurality of supporting structures 400, and the plurality of supporting structures 400 are arranged at intervals in the sealed cavity 500 to ensure the structural strength and stability of the wave-proof device.

[0098] In some embodiments, the plurality of support structures 400 are evenly arranged around the circumference of the flow tube 230 so as to evenly transmit the load on the two wave-breaking plates 100, thereby ensuring the stability and reliability of the wave-breaking structure.

[0099] In other embodiments, connectors are provided between the multiple support structures 400 to interconnect the multiple support structures 400 through the connectors, thereby improving the structural strength and supporting performance of the support structures 400. In other embodiments, the connectors may be connecting rods, connecting ring plates, and the like.

[0100] See Figure 1 and Figure 3 In this embodiment, the two wave-breaking plates 100, the first circulation plate 210, the second circulation plate 220, the circulation tube 230, the two first gaskets 310, and the two second gaskets 320 are hermetically connected to form a sealed cavity 500 between the two wave-breaking plates 100. The sealed cavity 500 can maintain a stable pressure due to the gas inside, so that the sealed cavity 500 can support the wave-breaking device, improve the structural strength and load-bearing capacity of the wave-breaking device, and thus facilitate protection of the wave-breaking device when transporting liquid substances or filling liquid substances in the liquid tank.

[0101] In some embodiments, the pressure in the sealed cavity 500 may be normal pressure.

[0102] In other embodiments, the pressure in the sealed cavity 500 can be adjusted. A regulating pipe (not shown) is provided on the tank body relative to the sealed cavity 500. The regulating pipe can extend into the sealed cavity 500 and communicate with the sealed cavity 500, so that a worker can adjust the air pressure in the sealed cavity 500 through the regulating pipe.

[0103] In other embodiments, when the pressure in the sealed cavity 500 is positive, the gas in the sealed cavity 500 can squeeze the wave-breaking plate, so that the wave-breaking plate is in a pre-stretched state, which can partially offset the compressive stress caused by external impact and ensure the structural stability of the wave-breaking structure.

[0104] See Figures 1 to 9When the liquid tank is transporting liquid material, the liquid material impacts the wave-breaking plate 100 due to the inertial force of the vehicle during travel. Part of the liquid material can flow back after impacting the wave-breaking plate 100, thereby reducing the kinetic energy of the liquid material through the impact; part of the liquid material can flow along the wave-breaking plate 100 and converge at the third communication hole 103, thereby reducing the kinetic energy of the impact of the liquid material; and part of the liquid material can flow through the wave-breaking device through the flow tube 230 to impact another part of the liquid material, thereby reducing the kinetic energy of the entire liquid material.

[0105] When liquid material impacts the wave-breaking plate 100, the sealed cavity 500 supports the wave-breaking device. Part of the load borne by the wave-breaking plate 100 is directly transferred to the tank body, while the remaining part is transferred to the tank body through the other wave-breaking plate 100, the first circulation plate 210, the second circulation plate 220, and the circulation tube 230. This effectively improves the conductivity between the wave-breaking device and the tank body, ensuring the structural strength, reliability, and stability of the wave-breaking device.

[0106] See Figures 1 to 9 The present application also provides a liquid tank comprising: a tank body (not shown) and a plurality of wave-proofing devices as described above. A receiving cavity for receiving liquid material is defined within the tank body. The wave-proofing devices are spaced apart in the receiving cavity along the axial direction of the tank body.

[0107] The plurality of wave-proof devices divide the accommodating chamber into a plurality of spaces, so that when the liquid material surges in the plurality of spaces, the plurality of wave-proof devices facilitate the reduction of the kinetic energy of the liquid material, thereby ensuring the safety and reliability of the liquid tank during transportation.

[0108] In some embodiments, the liquid tank of the present application, due to its internal wave-proof device with high structural strength and strong impact resistance, effectively ensures the safety and reliability of the liquid tank during transportation, so that the liquid tank can be used in a wide variety of fields.

[0109] In some embodiments, the liquid tank of the present application can be used not only to transport conventional liquid goods such as milk, soy sauce, and beer, but also to transport dangerous liquid goods such as liquid methane, gasoline, and potassium chlorate.

[0110] The present application also provides a liquid tank truck, which includes a vehicle body and the above liquid tank. The tank body is arranged on the vehicle body so as to be able to move with the vehicle body, thereby realizing the transportation of the liquid tank.

[0111] Although the present application has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary rather than restrictive. Since the present application can be embodied in various forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all changes and modifications that fall within the scope of the claims or their equivalents are intended to be covered by the appended claims.
