Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically to an elliptical PE plastic fire-fighting liquid tank. Background Technology

[0002] To prevent excessive sloshing of the liquid in the fire truck's tanks from damaging the tanks, especially during vehicle movement—such as when starting after a stop, changing speed, braking, turning, or experiencing bumps—the liquid inside the tanks can churn and surge violently, affecting not only the vehicle's speed and safe driving but also potentially causing cracks in the tank walls. Therefore, anti-sloshing devices are typically installed inside the tanks.

[0003] Existing anti-sloshing devices typically consist of multiple anti-sloshing plates arranged in a grid or X shape, which divide the tank's interior into several interconnected small cavities to protect the tank. However, long-term use has revealed that because the anti-sloshing plates bear a significant amount of liquid impact, they are prone to damage and have a short lifespan. Utility Model Content

[0004] The purpose of this invention is to provide an elliptical PE plastic fire-fighting liquid tank to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An elliptical PE plastic fire-fighting liquid tank includes a tank body. An anti-sloshing mechanism is provided inside the tank body. The anti-sloshing mechanism includes anti-sloshing horizontal plates and anti-sloshing vertical plates fixedly installed inside the tank body. The anti-sloshing vertical plates are interposed on each of the anti-sloshing horizontal plates, so that the anti-sloshing horizontal and vertical plates are arranged in a crisscross pattern. Multiple first water passage holes are provided on both sides of the anti-sloshing horizontal and vertical plates. Multiple anti-sloshing bodies are symmetrically arranged on both sides of the anti-sloshing horizontal and vertical plates, arranged in a row. Each anti-sloshing body is conical in shape and has an arc-shaped head fixedly installed at its end. A water inlet hole is provided on the arc-shaped head, and multiple water outlet holes are provided at the bottom of the anti-sloshing body. Both the water inlet and outlet holes communicate with the inner cavity of the anti-sloshing body.

[0007] Furthermore, there are multiple anti-sway horizontal plates and anti-sway vertical plates, and the anti-sway horizontal plates have passage holes.

[0008] Furthermore, the anti-sway body is connected to the inner cavity of the anti-sway body on the symmetrical side.

[0009] Furthermore, each of the aforementioned anti-sloshing cross plates is provided with a second water passage hole at its bottom.

[0010] Furthermore, the tank body is elliptical in shape.

[0011] Furthermore, the tank body is made of a single piece of plastic material.

[0012] Furthermore, the anti-sway bodies in adjacent rows are aligned.

[0013] The elliptical PE plastic fire-fighting liquid tank provided by this utility model has the following beneficial effects:

[0014] With the anti-sloshing mechanism in place, when liquid impacts the anti-sloshing horizontal or vertical plate, the liquid comes into contact with the anti-sloshing body. Some liquid enters from the inlet and flows out from the outlet, colliding with the liquid discharged from the outlet of the adjacent anti-sloshing body to reduce the liquid flow velocity. Some liquid moves along the outer surface of the anti-sloshing body to the anti-sloshing horizontal or vertical plate and collides with the liquid flowing on the outer surface of the adjacent anti-sloshing body, reducing the liquid flow velocity. Furthermore, the liquid that flows from the outlet or outer surface of the anti-sloshing body onto the anti-sloshing horizontal or vertical plate forms a liquid protective layer, effectively reducing the impact of the liquid in the fire-fighting liquid tank on the anti-sloshing horizontal and vertical plates, thereby extending their service life.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure.

[0026] Please see Figure 1-5 An elliptical PE plastic fire-fighting liquid tank includes a tank body 1. An anti-sloshing mechanism 2 is provided inside the tank body 1. The anti-sloshing mechanism 2 includes an anti-sloshing horizontal plate 21 and an anti-sloshing vertical plate 22 fixedly installed inside the tank body 1. The anti-sloshing vertical plate 22 is interposed on each of the anti-sloshing horizontal plates 21, so that the anti-sloshing horizontal plates 21 and anti-sloshing vertical plates 22 are arranged in a crisscross pattern. Multiple first water passage holes 23 are provided on both sides of the anti-sloshing horizontal plates 21 and anti-sloshing vertical plates 22. Multiple anti-sloshing bodies 3 are symmetrically arranged on both sides of the anti-sloshing horizontal plates 21 and anti-sloshing vertical plates 22, arranged in a row. Each anti-sloshing body 3 is conical in shape and has an arc-shaped head 31 fixedly installed at its end. A water inlet hole 32 is provided on the arc-shaped head 31. Multiple water outlet holes 33 are provided at the bottom of each anti-sloshing body 3. Both the water inlet hole 32 and the water outlet hole 33 communicate with the inner cavity of the anti-sloshing body 3. The tank body 1 is equipped with conventional fire-fighting liquid tank pipelines and interfaces such as an external water injection pipe, an internal rear water inlet pipe, and an overflow pipe. These are technical means known to those skilled in the art and will not be described in detail here.

[0027] When liquid impacts the anti-sloshing horizontal plate 21 or anti-sloshing vertical plate 22, the liquid comes into contact with the anti-sloshing body 3. Some liquid enters from the inlet hole 32 and flows out from the outlet hole 33, colliding with the liquid discharged from the outlet hole 33 of the adjacent anti-sloshing body 3 to reduce the liquid flow rate. Some liquid moves along the outer surface of the anti-sloshing body 3 to the anti-sloshing horizontal plate 21 or anti-sloshing vertical plate 22 and collides with the liquid flowing on the outer surface of the adjacent anti-sloshing body 3 to reduce the liquid flow rate. Furthermore, the liquid flowing from the outlet hole 33 or the outer surface of the anti-sloshing body 3 to the anti-sloshing horizontal plate 21 or the vertical plate forms a liquid protective layer, effectively reducing the impact of the liquid in the fire-fighting liquid tank on the anti-sloshing horizontal plate 21 and the anti-sloshing vertical plate 22, thereby improving their service life.

[0028] Furthermore, there are multiple anti-sway horizontal plates 21 and anti-sway vertical plates 22, and the anti-sway horizontal plates 21 are provided with passage holes 24 to facilitate maintenance by personnel.

[0029] Furthermore, the anti-sloshing body 3 is connected to the inner cavity of the anti-sloshing body 3 on the symmetrical side. This allows liquid to flow from one side of the anti-sloshing horizontal plate 21 or anti-sloshing vertical plate 22 through the anti-sloshing body 3 to the other side, thereby relieving the pressure of the first water passage 23 and the second water passage 25 and accelerating the flow rate of each independent liquid cavity.

[0030] Furthermore, each of the anti-sloshing cross plates 21 is provided with a second water passage hole 25 at its bottom to ensure that the liquid level in each liquid chamber remains consistent.

[0031] Furthermore, the tank 1 is elliptical in shape. A support platform is provided at the bottom of the tank 1, and the tank 1 is fixedly installed on the fire truck via the support platform. The elliptical shape provides better stability when placed. Compared to a square tank 1, it has no sharp edges or corners, resulting in a more uniform stress distribution when subjected to external forces, reducing the risk of damage caused by excessive local pressure.

[0032] Furthermore, the tank body 1 is made of a single piece of plastic. One-piece molding requires less welding, thus avoiding leakage problems caused by poor weld quality.

[0033] Furthermore, the anti-sway bodies 3 in adjacent rows are aligned.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
