Description

Technical Field

[0001] This utility model relates to the field of liquid transportation equipment, and in particular to a pressure vessel and a transport vehicle. Background Technology

[0002] Existing mobile pressure vessel tanks are equipped with internal baffles. These baffles are vertically installed within the tank and extend along its width, with both ends movably connected to the inner wall of the tank. This movable connection between the baffles and the tank body effectively improves the stress distribution on the baffles when subjected to liquid impact. However, existing baffles only serve a limited function of wave protection. Utility Model Content

[0003] The purpose of this invention is to solve the problem of the limited functionality of the internal baffles of existing pressure vessel tanks.

[0004] To solve the above-mentioned technical problems, this utility model provides a pressure vessel for mounting on the body of a transport vehicle, comprising a tank and a baffle plate. The two ends of the tank in the length direction are the front end and the rear end of the tank, respectively. The interior of the tank is provided with a cavity for storing a medium. The baffle plate is disposed in the cavity and connected to the tank. The width direction of the baffle plate is consistent with the width direction of the tank. The baffle plate includes a portion extending to the upper part of the cavity, forming a first portion for impeding the fluctuation of the upper medium in the cavity in the front-to-back direction. A wave-damping section is provided; wherein, a plurality of fluid through holes are distributed on the wave-damping plate, each fluid through hole having an inlet end and an outlet end, the diameter of the fluid through hole gradually decreasing from the inlet end to the outlet end; the inlet end of the fluid through hole located on the first wave-damping section faces the rear end of the tank body, and the outlet end of the fluid through hole located on the first wave-damping section faces the front end of the tank body, so that when the transport vehicle brakes, the medium in the tank enters the fluid through hole from the inlet end of the fluid through hole on the first wave-damping section and flows out from the outlet end.

[0005] In some embodiments of this application, the baffle plate includes a second baffle extending to the lower part of the cavity to form a second baffle for preventing the lower medium of the cavity from fluctuating in the front-to-back direction; the inlet end of the fluid through hole located on the second baffle faces the front end of the tank body, and when the medium in the lower part of the cavity flows from the front end of the tank body to the rear end of the tank body, the medium in the tank body can enter the fluid through hole from the inlet end of the fluid through hole on the second baffle and flow out from the outlet end.

[0006] In some embodiments of this application, the fluid passage is tapered or funnel-shaped.

[0007] In some embodiments of this application, the baffle plate includes a plate body and multiple pipe fittings. The plate body is connected to the tank body, and multiple through holes are spaced apart on the plate body. The multiple pipe fittings are spaced apart and distributed on one side of the plate body, with each pipe fitting corresponding to one of the multiple through holes. One end of each pipe fitting is fixedly connected to the plate body along its length and is flush with the side of the plate body. Fluid through holes are provided on the pipe fittings, with the inlet end of the fluid through hole located at the end of the pipe fitting closer to the plate body and the outlet end of the fluid through hole located at the end of the pipe fitting away from the plate body.

[0008] In some embodiments of this application, the pipe fitting includes a main body and a bending portion. One end of the main body is connected to the plate body, and the other end extends in a direction away from the plate body. The bending portion is disposed at the end of the main body away from the plate body, and the bending portion bends toward the side of the plate body.

[0009] In some embodiments of this application, the pressure vessel further includes a rotating shaft, the axial direction of which is the same as the width direction of the tank body, and the rotating shaft is rotatably connected to the tank body; at least three baffles are provided on the rotating shaft, the at least three baffles are evenly arranged along the circumference of the rotating shaft, and one end of the baffle in the length direction is fixedly connected to the rotating shaft, and the other end extends along the radial direction of the rotating shaft; when the rotating shaft rotates relative to the tank body, at least one baffle rotates to the upper part of the cavity to form the first baffle section.

[0010] In some embodiments of this application, the baffle plate has a folded edge on the side away from the rotating shaft; the rotating shaft is located in the middle of the tank in the height direction.

[0011] In some embodiments of this application, a bearing base is provided on the inner wall of the tank, and the rotating shaft is rotatably connected to the bearing base; the pressure vessel also includes a ratchet structure, which is disposed between the bearing base and the rotating shaft, and the ratchet structure is used to restrict the first wave-damping part from rotating toward the rear end of the tank.

[0012] In some embodiments of this application, one end of the rotating shaft extends beyond the outside of the tank body; the pressure vessel also includes a power generation device, which is connected to the rotating shaft in a transmission manner, enabling the rotating shaft to drive the power generation device to generate electricity.

[0013] In some embodiments of this application, multiple rotating shafts are provided, and the multiple rotating shafts are spaced apart along the length direction of the tank; multiple sets of power generation devices are configured, and the multiple sets of power generation devices are configured one-to-one with the multiple rotating shafts.

[0014] A transport vehicle includes a vehicle body and a pressure vessel, the pressure vessel being mounted on the vehicle body.

[0015] As can be seen from the above technical solution, the beneficial effects of this utility model are as follows: The pressure vessel of this application is mounted on the body of a transport vehicle. The pressure vessel includes a tank and a baffle plate. The baffle plate is disposed within the cavity of the tank, and the width direction of the baffle plate is consistent with the width direction of the tank. The baffle plate includes a first baffle portion extending to the upper part of the cavity to form a first baffle portion for impeding the fluctuation of the upper medium in the cavity in the front-to-back direction. When the transport vehicle brakes and moves, the fluctuating medium in the tank impacts the first baffle portion, thereby effectively improving the fluctuation and floating of the medium in the tank, reducing the impact of the medium on the tank, increasing the service life of the pressure vessel, and improving the driving safety of the transport vehicle. The baffle plate is equipped with fluid passages, each with an inlet and an outlet. The diameter of the fluid passages gradually decreases from the inlet to the outlet. The inlet of the fluid passage on the first baffle plate faces the rear end of the tank, while the outlet faces the front end. When the transport vehicle brakes, the medium inside the tank enters the fluid passage from the inlet and flows out from the outlet. Because the inlet diameter is larger and the outlet diameter is smaller, the medium's flow velocity accelerates as it passes through the fluid passage. The higher the flow velocity, the lower the pressure, which causes the medium temperature to drop. This reduces the medium temperature, slows down the pressure rise inside the tank, effectively improves the transport vehicle's driving safety, and enhances the baffle plate's functionality.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] See Figure 1 A transport vehicle includes a vehicle body 200 and a pressure vessel 100, the pressure vessel 100 being mounted on the vehicle body 200, enabling the vehicle body 200 to transport the medium loaded inside the pressure vessel 100 to a corresponding location. The transport vehicle can be a liquefied gas transport vehicle or a liquefied gas transport semi-trailer, meaning the medium stored inside the pressure vessel 100 is liquefied gas. It should be noted that the pressure vessel 100 can also be used to store other liquids.

[0028] See Figure 2The pressure vessel 100 includes a tank body 1 and a baffle plate 2. The tank body 1 is mounted on a vehicle body 200, and its length is aligned with the longitudinal direction of the vehicle body 200. The two ends along the length of the tank body 1 are the front end 13 and the rear end 14, respectively. The tank body 1 has an internal cavity 11 for storing the medium. The baffle plate 2 can be made of austenitic stainless steel, ensuring its strength even in the low-temperature environment of liquefied gas. The baffle plate 2 is disposed within the cavity 11 and connected to the tank body 1, thus enabling its installation within the tank body 1. The width of the baffle plate 2 is consistent with the width of the tank body 1.

[0029] The baffle plate 2 can extend at least partially to the upper part of the cavity 11, so that when the transport vehicle brakes and moves, the fluctuating upper medium in the cavity 11 of the tank 1 impacts the baffle plate 2, thereby effectively improving the fluctuation and floating of the medium in the tank 1, reducing the impact of the medium on the tank 1, increasing the service life of the pressure vessel 100, and improving the driving safety of the transport vehicle.

[0030] The baffle plate 2 can extend at least partially to the lower part of the cavity 11, so that when the transport vehicle brakes or accelerates, the medium located in the lower part of the cavity 11 impacts the lower part of the baffle plate 2, thereby effectively improving the fluctuation and floating of the medium in the tank 1, reducing the impact of the medium on the tank 1, increasing the service life of the pressure vessel 100, and improving the driving safety of the transport vehicle.

[0031] See Figure 2 and Figure 5 Specifically, the tank body 1 has bearing bases 12 on both side walls in the width direction, and the bearing bases 12 are located in the middle of the height direction of the tank body 1. The pressure vessel 100 also includes a rotating shaft 3, the axis of which is the same as the width direction of the tank body 1. The two ends of the rotating shaft 3 are rotatably connected to the tank body 1 through the bearing bases 12, so that the rotating shaft 3 is located in the middle of the height direction of the tank body 1. The baffle plate 2 is fixed on the rotating shaft 3, so that the baffle plate 2 can rotate relative to the tank body 1 through the rotating shaft 3, thereby allowing the baffle plate 2 to rotate to the upper part of the cavity 11 to form a first baffle section 21 for preventing the upper medium of the cavity 11 from fluctuating in the front-back direction; and the baffle plate 2 can rotate to the lower part of the cavity 11 to form a second baffle section 25 for preventing the lower medium of the cavity 11 from fluctuating in the front-back direction.

[0032] Multiple rotating shafts 3 are provided, spaced apart along the length of the tank body 1. Each rotating shaft 3 is equipped with a baffle plate 2, thereby increasing the number of baffle plates 2 provided along the length of the tank body 1 within the cavity 11. This enhances the baffle plate 2's ability to impede the fluctuation and floating of the medium, reduces the impact of the medium on the tank body 1, extends the service life of the pressure vessel 100, and improves the driving safety of the transport vehicle. It should be noted that a single rotating shaft 3 may also be provided.

[0033] When the tank 1 is filled with a medium, the pressure vessel 100 usually has a certain amount of gas phase space to prevent the pressure vessel 100 from being damaged when the medium expands due to temperature rise. However, when the transport vehicle brakes and moves, the surface of the medium has room to move, resulting in the most active fluctuation of the upper medium in the cavity 11. The baffle 2 of this application is configured to be rotatable to the upper part of the cavity 11, forming a first baffle 21 to prevent the upper medium in the cavity 11 from fluctuating in the front-to-back direction. This first baffle 21 can effectively block the fluctuation of the upper medium, reduce the impact of the medium on the tank 1, improve the service life of the pressure vessel 100, and improve the driving safety of the transport vehicle. The baffle 2 can also be rotatable to the lower part of the cavity 11, forming a second baffle 25 to prevent the lower medium in the cavity 11 from fluctuating in the front-to-back direction. This allows the baffle 2 located at the lower part of the cavity 11 to prevent the fluctuation of the lower medium.

[0034] In one embodiment, at least three baffle plates 2 are provided on each rotating shaft 3. The at least three baffle plates 2 are evenly arranged along the circumference of the rotating shaft 3, and one end of the baffle plate 2 in the length direction is fixedly connected to the rotating shaft 3, while the other end extends in the radial direction of the rotating shaft 3. This enables the baffle plate 2 to be rotatably connected to the tank 1 through the rotating shaft 3, and also allows the baffle plate 2 to rotate relative to the tank 1 when the medium impacts it.

[0035] The baffle plates 2 are configured with at least three pieces and evenly distributed along the circumference of the rotating shaft 3. This ensures that when the rotating shaft 3 rotates relative to the tank 1, at least one baffle plate 2 rotates to the upper part of the cavity 11, and at least one baffle plate 2 rotates to the lower part of the cavity 11. Thus, the baffle plates 2 can effectively block the fluctuations and floating of the medium in both the upper and lower parts of the cavity 11. Furthermore, the even distribution of the baffle plates 2 along the circumference of the rotating shaft 3 results in a more balanced stress distribution in the structure after the baffle plates 2 are connected to the rotating shaft 3, and smoother rotation of the rotating shaft 3 relative to the tank 1.

[0036] exist Figure 2In the illustrated embodiment, each rotating shaft 3 is equipped with four baffles 2, with an included angle of 90 degrees between adjacent baffles 2. This ensures that during the rotation of the rotating shaft 3 relative to the tank body 1, at least one baffle 2 is located at the upper part of the cavity 11, and at least one baffle 2 is located at the lower part of the cavity 11. Furthermore, some baffles 2 extend along the length of the tank body 1. During braking and driving, the baffles 2 located at the upper part of the cavity 11 block the fluctuations of the upper medium, the baffles 2 located at the lower part of the cavity 11 block the fluctuations of the lower medium, and the baffles 2 extending along the length of the tank body 1 block the vertical fluctuations of the medium. This improves the blocking effect on the fluctuations of the medium, reduces the impact of the medium on the tank body 1, increases the service life of the pressure vessel 100, and improves the driving safety of the transport vehicle. When the baffles 2 are rotated to an inclined position, they can block the fluctuations of the medium in both the forward / backward and vertical directions.

[0037] exist Figure 5 In the embodiment shown, there is a gap between the top of the baffle plate 2 and the top of the tank 1, and a gap between the bottom of the baffle plate 2 and the bottom of the tank 1, so that the medium inside the tank 1 can flow along the length of the tank 1, thereby realizing the adaptive pressure balance of the pressure vessel 100 in the length direction, ensuring that the center of gravity of the medium is located in the middle of the tank 1, and preventing the center of gravity of the medium from shifting to one end of the length direction of the tank 1.

[0038] When the baffle plate 2 rotates to the upper part of the cavity 11, one end of the baffle plate 2 in the length direction extends upward and is used to prevent the upper medium in the cavity 11 from fluctuating in the front-to-back direction. Hereinafter, the baffle plate 2 when rotated to the upper part of the cavity 11 is defined as the first baffle section 21, and the baffle plate 2 when rotated to the lower part of the cavity 11 is defined as the second baffle section 25.

[0039] See Figure 2 , Figure 3 , Figure 4 and Figure 5The baffle plate 2 has multiple fluid passages 22 distributed on it. Each fluid passage 22 includes an inlet end 221 and an outlet end 222, with the diameter of the fluid passage 22 gradually decreasing from the inlet end 221 to the outlet end 222. The inlet end 221 of the fluid passage 22 on the first baffle section 21 faces the rear end 14 of the tank body, while the outlet end 222 faces the front end 13 of the tank body. When the transport vehicle brakes, the medium in the tank body 1 enters the fluid passage 22 through the inlet end 221 of the fluid passage 22 on the first baffle section 21 and flows out through the outlet end 222. Because the diameter of the inlet end 221 is larger and the diameter of the outlet end 222 is smaller, the flow velocity of the medium will accelerate when passing through the fluid passage 22. The higher the flow velocity, the lower the pressure, resulting in a decrease in the temperature of the medium. This reduces the temperature of the medium and slows down the pressure rise inside the tank body 1, effectively improving the driving safety of the transport vehicle and enhancing the function of the baffle plate 2.

[0040] The inlet end 221 of the fluid through-hole 22 on the second wave-damping section 25 faces the front end 13 of the tank, and the outlet end 222 of the fluid through-hole 22 on the second wave-damping section 25 faces the rear end 14 of the tank. When the transport vehicle brakes and the medium in the upper part of the cavity 11 flows towards the front end 13 of the tank, the weight of the medium in the front end 13 of the tank increases, causing the medium in the lower part of the cavity 11 to flow from the front end 13 of the tank to the rear end 14 of the tank. This allows the medium to enter the fluid through-hole 22 from the inlet end 221 of the fluid through-hole 22 on the second wave-damping section 25 and flow out from the outlet end 222. Because the diameter of the inlet end 221 is larger and the diameter of the outlet end 222 is smaller, the flow velocity of the medium will accelerate when it passes through the fluid through-hole 22. The greater the flow velocity, the lower the pressure, resulting in a decrease in the temperature of the medium. This reduces the temperature of the medium, slows down the pressure rise inside the tank 1, effectively improves the driving safety of the transport vehicle, and also enhances the function of the wave-damping plate 2.

[0041] When the amount of medium in tank 1 is small and the transport vehicle accelerates, the medium in tank 1 enters the fluid passage 22 through the inlet end 221 of the fluid passage 22 on the second baffle 25 and flows out through the outlet end 222. The flow velocity of the medium increases as it passes through the fluid passage 22. The higher the flow velocity, the lower the pressure, which leads to a decrease in the temperature of the medium. This reduces the temperature of the medium and slows down the pressure rise inside tank 1, effectively improving the driving safety of the transport vehicle and enhancing the function of the baffle 2.

[0042] exist Figure 3In the illustrated embodiment, the baffle plate 2 includes a plate body 23 and multiple pipe fittings 24. One end of the plate body 23 is fixedly connected to a rotating shaft 3 along its length, and the other end extends radially along the rotating shaft 3. The width of the plate body 23 is the same as the width of the tank body 1. Multiple through holes are spaced apart on the plate body 23, connecting both sides of the plate body 23 along its thickness. Multiple pipe fittings 24 are spaced apart and distributed on one side of the plate body 23, and the length of the pipe fittings 24 is the same as the thickness of the plate body 23. The multiple pipe fittings 24 are arranged one-to-one with the multiple through holes, and one axial end of the pipe fitting 24 is fixedly connected to the plate body 23. Fluid through holes 22 are provided on the pipe fittings 24. The pipe fittings 24 with fluid through holes 22 can be tapered pipes, flared pipes, or other shapes of pipe fittings.

[0043] By configuring the baffle plate 2 as a plate body 23 and multiple pipe fittings 24, the thickness of the plate body 23 can be made relatively small. Furthermore, the fluid passages 22, made of a certain length through the pipe fittings 24, gradually decrease in length from the inlet end 221 to the outlet end 222, resulting in a smaller overall structural weight of the baffle plate 2. This reduces the overall weight of the pressure vessel 100 and the energy consumption of the transport vehicle. It should be noted that the baffle plate 2 can also consist only of a plate with a certain thickness, and the fluid passages 22 can be directly formed on the plate. The plate body 23 is rectangular, and the width direction of the plate body 23, the axial direction of the rotating shaft 3, and the width direction of the tank body 1 are consistent. This ensures that when the baffle plate 2 rotates relative to the tank body 1 via the rotating shaft 3, it will not guide the medium to one side of the width direction of the tank body 1, thus maintaining the balance of the medium in the width direction of the tank body 1 and improving the driving safety of the transport vehicle.

[0044] The pipe fitting 24 is welded to the plate body 23 to ensure the reliability of the connection between the pipe fitting 24 and the plate body 23, and to make the connection between the pipe fitting 24 and the plate body 23 more convenient and to realize automated production.

[0045] The inlet end 221 of the fluid through-hole 22 is located at the end of the pipe fitting 24 near the plate body 23, and the outlet end 222 of the fluid through-hole 22 is located at the end of the pipe fitting 24 away from the plate body 23, that is, the end of the pipe fitting 24 with the larger diameter is connected to the plate body 23. The end of the pipe fitting 24 connected to the plate body 23 is flush with the side of the plate body 23. When the medium impacts the baffle plate 2 located at the top of the cavity 11, the medium first impacts one side of the plate body 23, and then enters the fluid through-hole 22 from the inlet end 221 on the pipe fitting 24 and flows out from the outlet end 222, so that the medium is cooled down faster when passing through the fluid through-hole 22, and the pressure rise in the tank 1 is reduced. Furthermore, the end of the pipe fitting 24 connected to the plate body 23 is flush with the side of the plate body 23, so that when the medium flows from the side of the plate body 23 to the inlet end 221 of the fluid passage 22, it will not be blocked by the edge of the pipe fitting 24, thereby reducing the flow resistance of the medium, increasing the flow rate of the medium through the fluid passage 22, and improving the effect of slowing down the pressure rise in the tank 1.

[0046] exist Figure 3 In the illustrated embodiment, the fluid through-hole 22 is funnel-shaped, meaning the diameter of the fluid through-hole 22 gradually changes in curvature along the axial direction. It should be noted that the fluid through-hole 22 can also be tapered.

[0047] See Figure 4 In one embodiment, the pipe fitting 24 includes a main body 241 and a bent portion 242. One end of the main body 241 is connected to the plate body 23, and the other end extends away from the plate body 23. The bent portion 242 is located at the end of the main body 241 away from the plate body 23, and the bent portion 242 bends towards the plate body 23, causing the medium flow direction to change and flow in the opposite direction when the medium flows along the fluid through-hole 22. The bent portion 242 is spaced from the plate body 23, creating a medium between them. When the transport vehicle brakes and moves, the medium between the bent portion 242 and the plate body 23 moves forward and collides with the reverse-flowing medium formed after passing through the pipe fitting 24, thereby generating a localized vortex. This vortex counteracts the force of the other medium moving forward, effectively reducing medium waves, making the transport vehicle run more smoothly, improving driving safety and driver experience.

[0048] In one embodiment, the axis of the outlet end 222 of at least some of the pipe fittings 24 forms an angle with the thickness direction of the plate body 23, and the outlet ends 222 of multiple pipe fittings 24 may face different directions in the circumferential direction of the plate body 23. This enhances the localized eddy current effect generated by the collision of the reverse-flowing medium and the forward-flowing medium, effectively reducing medium waves, making the transport vehicle run more smoothly, improving driving safety and driver experience. For example, the outlet ends 222 of some pipe fittings 24 face the plate body 23 on both sides in the width direction, and the outlet ends 222 of some pipe fittings 24 face the plate body 23 on both sides in the height direction.

[0049] See Figure 2 and Figure 7 The main body 23 of the wave deflector 2 has a folded edge 231 on the side away from the rotating shaft 3, thereby improving the stress resistance of the wave deflector 2. In some embodiments, the folded edges 231 on the two wave deflectors 2 opposite to the rotating shaft 3 are in the same direction, such as... Figure 2 As shown. In some embodiments, the folded edges 231 on the two wave deflectors 2 opposite to the rotating shaft 3 are oriented in opposite directions, so that the center of gravity of the structure after the wave deflectors 2 are connected to the rotating shaft 3 is located on the rotating shaft 3, and the force is more balanced, as shown. Figure 7 As shown. It should be noted that the main body 23 of the wave deflector 2 can also be provided with folded edges 231 on both sides in the width direction, thereby improving the stress resistance of the wave deflector 2.

[0050] See Figure 5 In some embodiments, the tank body 1 is formed by sequentially splicing multiple baffles 2 along its width, thereby reducing the width of each baffle 2. When installing the baffles 2, they need to be moved from the manhole on the tank body 1 into the cavity 11 of the tank body 1 before installation. By sequentially splicing multiple baffles 2 and reducing the width of each baffle 2, it is easier to move the baffles 2 from outside the tank body 1 into the cavity 11 during installation, reducing the required manhole opening diameter on the tank body 1 and improving the load-bearing strength of the tank body 1. The main body 23 of each baffle 2 has a folded edge 231 in the width direction, which further improves the overall load-bearing strength of the baffle 2.

[0051] See Figure 6 The pressure vessel 100 also includes a ratchet structure 4, which is disposed between the bearing base 12 and the rotating shaft 3. The ratchet structure 4 is used to restrict the first anti-surge part 21 from rotating toward the rear end 14 of the tank body. Taking the direction in which the medium pushes the anti-surge plate 2 to rotate when the transport vehicle brakes as the clockwise direction, the ratchet structure 4 can prevent the medium from pushing the anti-surge plate 2 to rotate counterclockwise, so that the medium can only push the anti-surge plate 2 to rotate in the clockwise direction. This prevents the anti-surge plate 2 from repeatedly swinging under the push of the medium fluctuation, improves the anti-surge plate 2's obstruction effect on the medium fluctuation, thereby effectively improving the medium fluctuation and floating inside the tank body 1, reducing the impact of the medium on the tank body 1, increasing the service life of the pressure vessel 100, and improving the driving safety of the transport vehicle.

[0052] In some embodiments, the ratchet structure 4 includes a ratchet 41, a check pawl 42, and an elastic element 43. The ratchet 41 is fixed to the rotating shaft 3. One end of the check pawl 42 is rotatably connected to the bearing base 12, and the other end is a free end. One end of the elastic element 43 is connected to the check pawl 42, and the other end is connected to the bearing base 12. The elastic force of the elastic element 43 causes the free end of the check pawl 42 to abut against one circumferential side of the ratchet 41. Since the outer circumferential surface of the ratchet 41 is provided with ratchet teeth, the ratchet 41 can only rotate clockwise relative to the check pawl 42 and cannot rotate counterclockwise. This allows the baffle plate 2 to rotate clockwise relative to the tank 1, preventing the baffle plate 2 from repeatedly oscillating under the influence of medium fluctuations. The elastic element 43 is preferably a spring.

[0053] In some embodiments, the ratchet structure 4 does not include the elastic element 43; that is, the ratchet structure 4 includes a ratchet 41 and a check pawl 42. The ratchet 41 is fixed to the rotating shaft 3, and one end of the check pawl 42 is rotatably connected to the bearing base 12, while the other end is a free end. The free end of the check pawl 42 abuts against one circumferential side of the ratchet 41 under its own weight. Since the outer circumferential surface of the ratchet 41 is provided with ratchet teeth, the ratchet 41 can only rotate clockwise relative to the check pawl 42 through the engagement of the check pawl 42 with the ratchet teeth on the ratchet 41. When the ratchet 41 rotates counterclockwise relative to the check pawl 42, mechanical interference occurs because the check pawl 42 abuts against the ratchet teeth, thus preventing it from rotating counterclockwise. This arrangement ensures that the baffle plate 2 can only rotate clockwise relative to the tank 1, preventing the baffle plate 2 from repeatedly swaying under the influence of the medium's fluctuations.

[0054] See Figure 2 In some embodiments, one end of the rotating shaft 3 extends beyond the outside of the tank body 1. The pressure vessel 100 also includes a power generation device 5, preferably a generator. The power generation device 5 is located outside the tank body 1, and the rotor of the power generation device 5 is connected to the rotating shaft 3. When the medium pushes the baffle plate 2 to rotate the rotating shaft 3, the rotating shaft 3 drives the rotor of the power generation device 5 to rotate. The rotation of the rotor will cut magnetic field lines in the magnetic field. According to Faraday's law of electromagnetic induction, this will induce an electromotive force in the stator coil of the power generation device 5, thereby generating a current, thus realizing the power generation of the power generation device 5. This realizes the conversion of the kinetic energy of the medium into electrical energy for storage and reuse, making full use of the kinetic energy of the medium, and achieving energy conservation and emission reduction. The electricity generated by the power generation device 5 can be stored in a battery.

[0055] In some embodiments, the rotating shaft 3 and the power generation device 5 are provided with a gear transmission structure 6, and power is transmitted through the gear transmission structure 6. For example, the gear transmission structure 6 includes a first gear and a second gear. The first gear is fixed on the rotating shaft 3, and the second gear is fixed on the rotor of the power generation device 5. The second gear meshes with the first gear. The diameter of the second gear is smaller than the diameter of the first gear, which reduces the torque requirement when the rotating shaft 3 drives the rotor of the power generation device 5 to rotate, reduces the difficulty of the rotating shaft 3 driving the power generation device 5 to generate electricity, and increases the rotational speed of the rotor of the power generation device 5, thereby improving the power generation efficiency of the power generation device 5.

[0056] Multiple rotating shafts 3 are provided, spaced apart along the length of the tank body 1. Multiple sets of power generation devices 5 are configured, each corresponding to one of the multiple rotating shafts 3. It should be noted that the multiple rotating shafts 3 can also be connected to the same power generation device 5 via a transmission structure. The transmission structure can be a gear transmission structure 6, a chain transmission structure, or a synchronous belt transmission structure.

[0057] In some embodiments, the pressure vessel 100 may not be equipped with a power generation device 5, and the rotating shaft 3 may be connected to an external device that requires torque, thereby realizing the recovery and utilization of the kinetic energy of the medium inside the tank 1. The external device that requires torque may be a cooling fan, etc.

[0058] In some embodiments, the pressure vessel 100 may not have a rotating shaft 3. The baffle plate 2 is connected to the inner wall of the tank 1, and the baffle plate 2 extends vertically along its length. The upper end of the baffle plate 2 extends to the upper part of the cavity 11, and the lower end of the baffle plate 2 is located at the lower part of the cavity 11, thereby enabling the baffle plate 2 to prevent the medium in the cavity 11 from fluctuating in the front-to-back direction. The baffle plate 2 is provided with fluid through holes 22, and the fluid through holes 22 located at the upper part of the baffle plate 2 and the fluid through holes 22 located at the lower part of the baffle plate 2 have opposite orientations. It should be noted that the baffle plate 2 may only have fluid through holes 22 at its upper part, and the lower part of the baffle plate 2 may not have fluid through holes 22. There may or may not be a gap between the top of the baffle plate 2 and the inner wall of the tank 1.

[0059] The pressure vessel 100 of this application is mounted on the body 200 of a transport vehicle. The pressure vessel 100 includes a tank 1 and a baffle 2. The baffle 2 is disposed in the cavity 11 of the tank 1. The width direction of the baffle 2 is consistent with the width direction of the tank 1. The baffle 2 includes a first baffle portion 21 extending to the upper part of the cavity 11 to form a first baffle portion 21 for impeding the upper medium of the cavity 11 from fluctuating in the front-to-back direction. When the transport vehicle brakes and moves, the fluctuating medium in the tank 1 impacts the first baffle portion 21, thereby effectively improving the fluctuation and floating of the medium in the tank 1, reducing the impact of the medium on the tank 1, improving the service life of the pressure vessel 100, and improving the driving safety of the transport vehicle. The baffle plate 2 is provided with a fluid passage 22, which includes an inlet end 221 and an outlet end 222. The diameter of the fluid passage 22 gradually decreases from the inlet end 221 to the outlet end 222. The inlet end 221 of the fluid passage 22 on the first baffle section 21 faces the rear end 14 of the tank body, and the outlet end 222 of the fluid passage 22 on the first baffle section 21 faces the front end 13 of the tank body. When the transport vehicle brakes, the medium in the tank body 1 enters the fluid passage 22 from the inlet end 221 of the fluid passage 22 on the first baffle section 21 and flows out from the outlet end 222. Since the diameter of the inlet end 221 is larger and the diameter of the outlet end 222 is smaller, the flow rate of the medium will accelerate when it passes through the fluid passage 22. The higher the flow rate, the lower the pressure, which leads to a decrease in the temperature of the medium. This can reduce the temperature of the medium and slow down the pressure rise in the tank body 1, effectively improving the driving safety of the transport vehicle and increasing the function of the baffle plate 2.
