[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] Please see Figure 1-3 The present invention provides the following technical solution: a PE material liquid flow energy storage battery tank structure, including a tank body 1 and a manhole 101 formed on the upper end of the tank body 1. A manhole cover is connected to the manhole 101, and a liquid distribution pipe interface is reserved on the cover. A support part 11 is formed on one side of the tank body 1.

[0026] Specifically, tank 1 is made of PE material and is blow-molded in one piece. PE material has excellent ductility and can withstand a certain amount of deformation. Moreover, PE material has high weldability, and the weld joint is safe and reliable, reducing the risk of leakage at the joint. At the same time, PE material has excellent overall weather resistance and can withstand working conditions of -40℃ to 50℃, increasing the service life of tank 1.

[0027] A protrusion 12 is formed between the upper end of the support 11 and the side of the tank 1. A manhole 101 is located between the tank 1 and the protrusion 12. At least three sides are formed on the protrusion 12 below the manhole 101.

[0028] Specifically, to ensure the strength of the side of the protrusion 12, a vertical second reinforcing rib 1202 is formed on the side of the protrusion 12; to strengthen the structural strength between the tank body 1 and the protrusion 12, a first reinforcing strip 102 is formed around the manhole 101 at the upper end of the tank body 1, and a second reinforcing strip 1201 is formed at the upper end of the protrusion 12 and connected to the first reinforcing strip 102. The first reinforcing strip 102 and the second reinforcing strip 1201 are close to the manhole 101, further strengthening the structural strength of the manhole 101 on the tank body 1.

[0029] Furthermore, the tank body 1 has two sets of first interfaces 105 formed on the side of the support part 11 near the support part 11, and a second interface 1203 is formed on the side of the protrusion 12. In this embodiment, the first interface 105 and the second interface 1203 are in a closed state when the storage tank is formed. Through the symmetrically arranged first interfaces 105, the appropriate pipeline layout can be selected according to the position of the liquid outlet main pipe 2 and the return pipe 9. After determining the orientation, the corresponding interface is opened, and the joint is connected by hot melt welding. This has better adaptability, and there is no need to customize the combination of multiple storage tanks. In order to ensure the reliability of hot melt welding, the joint is also formed of PE material. The second interface 1203 can be used for liquid leveling when multiple storage tanks are combined.

[0030] Furthermore, in order to strengthen the strength of the manhole 101 in the tank body 1, a symmetrical solid block 103 is formed on the top of the tank body 1 near the manhole 101. The solid block 103 is connected to the side of the tank body 1 and a lifting lug 104 is formed at the top. In this embodiment, the solid block 103 can simultaneously strengthen the manhole 101 and the lifting lug 104, improve the compressive strength of the stressed parts, and thus make the lifespan of each part of the overall storage tank more uniform.

[0031] Furthermore, in order to evenly distribute the pressure on the manhole 101 onto the tank body 1 and the support 11, the protrusion 12 is located in the middle between the support 11 and the tank body 1, and the protrusion 12 is flush with the top surface of the tank body 1.

[0032] Furthermore, the top of the support part 11 is formed with a first reinforcing rib 1101, which is arranged horizontally to enhance the compressive strength of the top surface of the support part 11.

[0033] One specific embodiment of this utility model is as follows: Figure 4 As shown, two tanks 1 are used as positive and negative electrolyte storage tanks for storing system energy. The support parts 11 on the two tanks 1 are close to each other. The support parts 11 and the protrusions 12 have reserved space for the first interface 105 to connect with the liquid outlet pipe 2 and the return pipe 9. Valves are provided on the liquid outlet pipe 2 and the return pipe 9. At the same time, space is also reserved for the installation of the circulation pump 8 and the liquid level balance pipe 10. The above mutual adaptation can allocate space more reasonably and facilitate the neat arrangement of pipes on the tanks 1.

[0034] Specifically, each tank 1 has a set of circulation components, which are used to simultaneously drive the electrolyte inside the two tanks 1 to flow to the fuel cell stack system (not shown in the figure) to carry out chemical reactions to complete charging and discharging and then return. The two tanks 1 are connected to each other through the second interface 1203 and the liquid level balance pipe 10. The liquid level balance pipe 10 is equipped with a valve. The circulation components include the main outlet pipe 2, the distributor 3, the outlet branch pipe 4, the return branch pipe 5, the return device 6, the main return pipe 7, the circulation pump 8, and the return pipe 9. More specifically, when in use, the circulation pump 8 is started to work, and the electrolyte flows through... The electrolyte is drawn out from the tank 1 through the main outlet pipe 2 and distributed to several outlet branch pipes 4 under the action of the distributor 3. The outlet branch pipes 4 transport the electrolyte to the fuel cell stack system and provide power. The electrolyte after the action is collected in the return liquid device 6 through the return liquid branch pipe 5, and then flows through the return liquid main pipe 7, the circulation pump 8, and the return pipe 9, and finally returns to the tank 1. In this embodiment, the tank 1 is also equipped with a pipeline (not shown in the figure) to fully connect the main outlet pipe 2 and the return pipe 9 with the electrolyte in the tank 1, and to ensure the uniform mixing of the electrolyte inside the tank 1 by using the circulation effect.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
