Description

Technical Field

[0001] This utility model relates to the field of LPG tank truck technology, and in particular to a wave deflector for LPG tank trucks that is designed to prevent impact and vibration. Background Technology

[0002] Mobile pressure vessels, such as LPG tank trucks, are crucial equipment widely used in the transportation of liquefied petroleum gas and other hazardous chemicals. Multiple baffles are installed inside the tank of an LPG tank truck. These baffles are designed to mitigate the fluctuations and impacts of the liquid inside the tank during transportation, reducing the risk of tank rupture due to long-distance, direct, and intense impacts on the end caps or partitions, thus improving the stability and safety of the tank truck. In addition, baffles also enhance vehicle stability, reduce the impact of rear-end disturbances on vehicle stability, and decrease noise and vibration generated by airflow over the tank truck body, improving driving comfort. However, in actual use, because the baffles have a simple structure and lack cushioning function—only having holes for liquid to pass through—various factors such as uneven road surfaces, vehicle acceleration and deceleration, turning, and bumps can cause impact and vibration loads on the baffles. These complex dynamic loads can damage the baffles, potentially leading to fatigue cracks or even deformation, posing safety hazards. Therefore, impact and vibration resistant baffles for LPG tank trucks are needed to meet these requirements. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing LPG tank truck baffles that lack buffering function, and to propose an LPG tank truck baffle that is designed to prevent impact and vibration.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design of a wave deflector for LPG tank trucks to prevent impact and vibration, including a wave deflector with a first hole through it, and multiple springs fixed in a circular pattern around the first hole on both sides of the wave deflector. A buffer plate is fixed to the multiple springs on the same side of the wave deflector, and multiple second holes are through it on each buffer plate.

[0006] Preferably, the edge of the wave deflector is provided with a groove.

[0007] Preferably, a limit mechanism is fixed between the wave deflector and the two buffer plates.

[0008] Preferably, the limiting mechanism includes multiple limiting posts, which are arranged circumferentially through the wave deflector plate with the first hole as the center, and the multiple limiting posts and the wave deflector plate are slidably connected, with both ends of each limiting post fixed to two buffer plates.

[0009] Preferably, a fixing component is fixed between each of the buffer plates and each of the limiting posts.

[0010] Preferably, the fixing component includes a threaded hole, which is located at the top of the limiting post. A threaded rod is threaded in the threaded hole, and the threaded rod is threaded through the buffer plate and fixed with a baffle.

[0011] Preferably, the baffle has a hexagonal structure.

[0012] The shock-absorbing and vibration-damping baffle for LPG tank trucks proposed in this utility model has the following advantages: During use, the baffle utilizes multiple springs to allow the buffer plates on both sides of the baffle to alternately approach the baffle. With the assistance of multiple springs and two buffer plates, the liquid impacting the baffle can be buffered, thereby protecting the multiple baffles inside the LPG tank truck, extending the service life of the baffles, and ensuring the effectiveness and safety of the LPG tank truck.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1: Refer to Figure 1 , 4 5. A shock-absorbing baffle for LPG tank trucks, comprising a baffle 1, a first hole 2 penetrating through the baffle 1, and a groove 3 at the edge of the baffle 1. When the baffle 1 is installed in the tank of the LPG tank truck, the edge of the baffle 1 with the groove 3 is located at the bottom of the tank of the LPG tank truck. The groove 3 prevents the liquid in the tank of the LPG tank truck from being blocked by the baffle 1 and thus prevents the liquid from being obstructed from flowing out. Multiple springs 4 are fixedly arranged in a circular pattern around the first hole 2 on both sides of the baffle 1. A buffer plate 5 is fixedly attached to the multiple springs 4 on the same side of the baffle 1. Each buffer plate 5 has multiple second holes 6 penetrating through it. With the assistance of the multiple springs 4, the two buffer plates 5 and the multiple springs 4 work together to block the liquid impacting the baffle 1, thereby reducing the force and vibration generated by the impact of the baffle 1 on the baffle 1.

[0021] During use, with the assistance of multiple springs 4, the buffer plates 5 on both sides of the baffle 1 can alternately approach the baffle 1. With the assistance of multiple springs 4 and two buffer plates 5, the liquid impacting the baffle 1 can be buffered, thereby protecting the multiple baffles 1 inside the LPG tanker, extending the service life of the baffles 1, and ensuring the effectiveness and safety of the LPG tanker.

[0022] Example 2: In Example 1, due to the characteristics of the multiple springs 4, when liquid impacts the buffer plate 5, it is impossible to guarantee that the buffer plate 5 will move closer to or further away from the anti-surge plate 1. This can easily damage the multiple springs 4 without reducing the effectiveness of the buffer plate 5. (Refer to...) Figure 1-4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that a limiting mechanism is fixed between the wave deflector 1 and the two buffer plates 5. The limiting mechanism includes multiple limiting posts 7, which are arranged circumferentially on the wave deflector 1 with the first hole 2 as the center. The multiple limiting posts 7 and the wave deflector 1 are slidably arranged. Both ends of each limiting post 7 are fixed on the two buffer plates 5. The arrangement of multiple limiting posts 7 will not affect the buffer plates 5 from moving closer to or away from the wave deflector 1 under the impact of the liquid, and can also limit the movement path of the buffer plates 5, allowing the buffer plates 5 to move closer to or away from the wave deflector 1 in a horizontal manner. This can protect the multiple springs 4, extend the service life of the multiple springs 4, and also ensure the effectiveness of the buffer plates 5.

[0023] Each buffer plate 5 and each limiting post 7 is fixed with a fixing component. With the assistance of the fixing component, the buffer plate 5 and the limiting post 7 can be fixed and disassembled at the same time, which facilitates the replacement of the limiting post 7. The fixing component includes a threaded hole 10, which is located on the top of the limiting post 7. A threaded rod 9 is threaded in the threaded hole 10. The threaded rod 9 is threaded and passes through the buffer plate 5 and is fixed with a baffle 8. The baffle 8 has a hexagonal structure. The hexagonal structure of the baffle 8 facilitates the turning of the threaded rod 9 and prevents the threaded rod 9 from slipping, ensuring that the threaded rod 9 can be turned smoothly.

[0024] When in use, with the assistance of multiple limit posts 7, the movement of the two buffer plates 5 towards or away from the baffle plate 1 is restricted by the preset path. When workers enter the tank of the LPG tanker to inspect or maintain the baffle plate 1, the threaded rod 9 can be turned by the baffle 8, which can disengage the threaded rod 9 from the threaded hole 10, making it convenient to inspect or replace the limit posts 7.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
