Large shaking of the liquid will also affect the driving stability of the vehicle and increase the risk of accidents such as rollovers. In the prior art, although wave-breaking plates are added to the tank body to slow down the fluctuations of liquid hazardous chemicals, large fluctuations will still occur when the vehicle speed changes significantly and turns, thus affecting the stability of the vehicle body.

[0031] Reference Figure 1~Figure 4An embodiment of the present invention proposes a storage device for a liquid hazardous chemical transport vehicle, which is used to store and transport liquid hazardous chemicals, including a tank body 1, wherein the tank body 1 has a main oil chamber 101; a first wave-breaking plate 2 is arranged in the main oil chamber 101, and there are a plurality of first wave-breaking plates 2, and the plurality of first wave-breaking plates 2 separate the main oil chamber 101 into a plurality of sub-oil chambers 102, and the first wave-breaking plate 2 has a first connecting port 201, and the first connecting port 201 connects the plurality of sub-oil chambers 102; a guide plate 3 is arranged on one side of the first connecting port 201.

[0032] In this embodiment, the storage device for liquid hazardous chemicals transport vehicles includes a tank body 1 for storing and transporting liquid hazardous chemicals, and a main oil chamber 101 is formed inside the tank body 1. A plurality of first wave-breaking plates 2 are arranged in the main oil chamber 101, and these first wave-breaking plates 2 divide the main oil chamber 101 into a plurality of oil sub-chambers 102. Each first wave-breaking plate 2 is provided with a first connecting port 201 for connecting adjacent oil sub-chambers 102. A guide plate 3 is installed on one side of the first connecting port 201. By providing a plurality of first wave-breaking plates 2 to divide the main oil chamber 101 into a plurality of oil sub-chambers 102, the fluctuation amplitude of liquid hazardous chemicals during transportation can be effectively reduced, the impact force borne by the tank body 1 can be reduced, the risk of structural fatigue damage and leakage of the tank body 1 can be reduced, and the transportation safety can be improved. The first connecting port 201 ensures the flow of oil between the oil sub-chambers 102 to avoid excessive local pressure. The setting of the guide plate 3 can guide the flow of oil at the first connecting port 201, making the flow of oil at the first connecting port 201 smoother, further reducing fluctuations and impacts, and also helping to maintain the stability of vehicle driving and reduce the probability of accidents such as rollovers.

[0033] Further, the direction of travel of the vehicle is defined as the front, and the opposite direction is the rear. The first wave-breaking plate 2 has an upper guide portion 202 and a lower guide portion 203. The upper guide portion 202 and the lower guide portion 203 are both inclined and arranged at an angle to each other. The end of the upper guide portion 202 and the lower guide portion 203 that are close to each other is located in the front, and the end that is away from each other is located in the rear. The first connecting port 201 and the guide plate 3 are both arranged on the lower guide portion 203, and the guide plate 3 is located on the side of the lower guide portion 203 close to the rear. The side of the upper guide portion 202 close to the rear has a first guide slope 204, and the side of the lower guide portion 203 close to the rear has a second guide slope 205. The guide plate 3 and the second guide slope 205 are arranged at an angle, and the liquid hazardous chemicals flow through the first guide slope 204, the second guide slope 205, the guide plate 3 and the first connecting port 201 in sequence and enter the adjacent oil distribution chamber 102 in the front.

[0034] In this embodiment, considering that when the vehicle decelerates, the oil in the tank body 1 surges forward under inertia, the design of this solution can make the liquid hazardous chemicals flow through the first guide slope 204, the second guide slope 205, the guide plate 3 and the first connecting port 201 in sequence to enter the adjacent oil separation chamber 102 in front during this process. The first guide slope 204 provides a downward guiding effect for the surging liquid hazardous chemicals and can slow down the fluctuation speed of the liquid hazardous chemicals. Under the guiding action of the first guide slope 204, the surging liquid hazardous chemicals flow downward, and after the receiving guidance and buffering action of the second guide slope 205, they enter the front oil separation chamber 102 through the first connecting port 201. Compared with the wave-breaking plate in the prior art, the setting of this solution can guide the liquid hazardous chemicals that surge forward after the speed is reduced to another oil separation chamber 102 after multiple decelerations, and the guiding process can avoid direct forward impact as much as possible, so that the internal oil can maintain a good and stable fluctuation state under drastic speed changes. This design significantly improves the stability of oil fluctuations in the tank body 1, effectively reduces the impact force of liquid hazardous chemicals when they surge, reduces damage to the structure of the tank body 1, and helps to ensure the stability and safety of vehicle driving, especially in emergency braking or frequent speed changes. It can effectively avoid the risk of loss of control caused by large fluctuations in oil and improve the reliability of the transportation process.

[0035] Furthermore, the lower guide portion 203 has a third guide slope 206 on the side close to the front, and the liquid hazardous chemicals in the oil separation chamber 102 located in front of the guide plate 3 flow through the third guide slope 206, the first connecting port 201 and the guide plate 3 in sequence into the adjacent oil separation chamber 102 at the rear.

[0036] In this embodiment, when the vehicle decelerates, the oil will flow to the front oil separation chamber 102. In order to keep the overall liquid level stable, the oil will also flow back to the rear oil separation chamber 102. The setting of the third guide slope 206 further provides guidance and buffering for this process, so that the forward and backward agitation of the oil can be buffered and diverted, and the oil can be restored to stability to a great extent within a fluctuation process. In addition, this process is also effective when the vehicle accelerates, but large transport vehicles usually do not have too violent acceleration movements, so this solution has a more significant calming effect on the oil whose initial movement is to surge forward. This not only optimizes the flow path of the oil under different driving conditions, reduces the disordered fluctuations and impacts of the oil, but also can effectively balance the pressure of various parts in the tank body 1 and reduce the impact of the oil on the tank body 1. Compared with the case without this design, the service life of the tank body 1 and the safety of transportation are greatly improved. At the same time, it helps to maintain the stability of the vehicle under various driving conditions and reduce the risk of vehicle loss of control due to unstable oil flow.

[0037] Furthermore, there are a plurality of first communication ports 201 and guide plates 3 arranged on the lower guide portion 203 .

[0038] In this embodiment, multiple first communication ports 201 and guide plates 3 are provided to increase the channels and guiding methods for the oil to flow between the oil separation chambers 102. This makes the flow of the oil more uniform and orderly, can more effectively disperse and buffer the fluctuation energy of the oil, further reduce the impact of the oil on the tank body 1, and improve the stability and safety of the tank body 1.

[0039] Furthermore, the first wave-breaking plate 2 also has a side guide portion 207, and the side guide portions 207 are arranged in pairs. The two side guide portions 207 are located on both sides of the upper guide portion 202 and the lower guide portion 203. The side guide portion 207 is located at the angle between the upper guide portion 202 and the lower guide portion 203, and the side guide portion 207 and the upper guide portion 202 and the lower guide portion 203 form an angle together. The side guide portion 207 has a second connecting port 208, and the second connecting port 208 connects two adjacent oil distribution chambers 102.

[0040] In this embodiment, the side guide 207 is mainly provided for lateral fluctuations caused by vehicle turning, etc. When the vehicle turns, the second connecting port 208 of the side guide 207 can effectively guide the flow of oil between adjacent oil distribution chambers 102, thereby buffering and dispersing the lateral impact force and reducing the lateral fluctuation of the oil. This helps to reduce the lateral pressure on the tank body 1, avoids damage to the tank body 1 due to uneven lateral force, and improves the stability and safety of the tank body 1 in special driving conditions such as turning. Compared with the case without the side guide 207, it can more comprehensively cope with various complex driving conditions.

[0041] Furthermore, a fourth flow guiding slope 209 is provided on one side of the side guide portion 207 close to the rear, and the liquid hazardous chemicals flow through the fourth flow guiding slope 209 and the second connecting port 208 in sequence into the adjacent oil separation chamber 102 in the front.

[0042] In this embodiment, the fourth flow guide slope 209 provides a good guiding effect for the liquid hazardous chemicals to enter the front adjacent oil separation chamber 102 through the second communication port 208. This allows the liquid hazardous chemicals to flow more smoothly and orderly between the oil separation chambers 102 during vehicle driving, especially under complex dynamic conditions such as turning, acceleration, deceleration, etc., thereby effectively reducing the fluctuation and impact of the liquid hazardous chemicals, reducing the impact force on the tank body 1, and helping to maintain the stability and safety of the tank body 1.

[0043] Furthermore, the first connecting opening 201 on the first wave-breaking plate 2 is gradually reduced from the rear to the front, and the height of the guide plate 3 is gradually reduced.

[0044] In this embodiment, the front of the tank body 1 is the cab, and the first connecting port 201 on the first wave-breaking plate 2 near the front gradually shrinks, which can make the flow of liquid hazardous chemicals into the oil distribution chamber 102 closest to the cab less and slower, so that the core position of the vehicle drive will not undergo a large change in the center of gravity, making the vehicle driving state more stable, and at the same time, it can also effectively and gradually slow down the flow speed and fluctuation amplitude of the oil. When the vehicle is driving, this gradually changing structure can better disperse and buffer the energy of the oil and reduce the impact force of the front oil on the tank body 1. Especially in emergency braking or other sudden situations, it can reduce the violent surge of the front oil, reduce the risk of damage to the tank body 1, and improve the safety of transportation. It should be noted that the reduction of the first connecting port 201 and the reduction of the height of the guide plate 3 are interpreted as defining the width direction of the vehicle body as the width direction of the vehicle, which is essentially a shortening of the width parallel to its own plane, rather than a shortening of the width along the width direction of the vehicle.

[0045] Furthermore, the second wave-breaking plate 4 is arranged in the main oil chamber 101 and is located behind the first wave-breaking plates 2 , and a tail space 104 is formed between the second wave-breaking plate 4 and the inner wall of the main oil chamber 101 .

[0046] In this embodiment, the tail space 104 is designed to assist the front several oil sub-cavities 102. During the driving process of the vehicle, when the oil fluctuates, it reaches the tail space 104 after the initial buffering of the front oil sub-cavity 102. The tail space 104 provides a new buffer area for the overall main oil cavity 101, which can accommodate and buffer part of the oil, while balancing the oil fluctuations and ensuring the stability inside the tail space 104. This design takes into account the need for stability of the rear of the vehicle. Through the buffering effect of the tail space 104, the impact of the oil on the rear of the tank body 1 is further reduced, so that the force on the rear of the tank body 1 is more uniform, and the risk of damage to the rear structure of the tank body 1 is reduced.

[0047] Furthermore, the second wave-breaking plate 4 has a third connecting port 401 , which is used to connect the oil separation chamber 102 and the tail space 104 on both sides of the second wave-breaking plate 4 , and the third connecting port 401 faces the bottom of the tail space 104 .

[0048] In this embodiment, the third communication port 401 is designed to face the bottom of the tail space 104, so that during the flow and fluctuation of the oil, the oil can be more effectively guided into the tail space 104, achieving a smooth transition and buffering of the oil. The shape and structure of the third communication port 401 can also provide a buffering and guiding effect for the oil again. The flow of the oil is made more stable and orderly, and the impact and disordered fluctuation of the oil are reduced. The control ability of the oil fluctuation is enhanced.

[0049] Furthermore, the top of the tail space 104 has an arc-shaped guide portion 103, the top of the second wave-breaking plate 4 has a fourth connecting port 402, the arc-shaped guide portion 103 partially passes through the fourth connecting port 402, and a slow flow channel 403 is formed between the arc-shaped guide portion 103 and the fourth connecting port 402.

[0050] In this embodiment, since the irregular fluctuations of the oil are mainly concentrated in the upper layer, when the oil flows out of the tail space 104, the arc-shaped guide part 103 can play a role, so that the outflowing liquid can achieve smooth flow. The fluctuations of the upper layer of oil will not directly impact the plane, and the oil from all directions can be buffered and guided to a stable state by the arc-shaped guide part 103. At the same time, one end of the second wave-breaking plate 4 passes through the fourth connecting port 402, and no matter in which direction the oil flows through the fourth connecting port 402, it will be buffered. This design allows the oil entering the tail space 104 and flowing out of the tail space 104 to eventually be in a stable state. It effectively reduces the impact of the violent fluctuations of the oil in the upper layer on the structure of the tank body 1 and reduces the potential risks caused by the impact of the oil. The stability of the tail during vehicle transportation can better ensure the overall stability of the vehicle.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
