Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to a directional pressure relief explosion-proof energy storage container. Background Art

[0002] As energy storage technology continues to mature, energy storage equipment and energy storage systems are also developing rapidly, especially the increasing demand for energy storage power stations on the grid and user sides. By integrating energy storage equipment and energy storage systems in containers, the impact of the external environment on the energy storage equipment and energy storage systems can be avoided, ensuring the normal and stable operation of the energy storage equipment and energy storage systems.

[0003] The energy storage container in the prior art is usually equipped with a battery pack. When the battery pack works abnormally and the fire protection system cannot properly handle the abnormality, the battery pack is prone to explosion under high temperature and high pressure. The box structure of the energy storage container in the prior art is usually similar to that of an ordinary container. Under the instantaneous pressure of the explosion, the container will break in all directions, thereby causing damage to the surrounding equipment or personnel, and thus causing greater losses. For this reason, an energy storage box-changing fire protection system disclosed in utility model patents such as CN201921008015 will be provided with an explosion-proof cover plate on the top, and it will be locked by a locking mechanism (to prevent it from being opened at will and causing foreign objects to enter), so that when an explosion occurs inside the energy storage box, the explosion force can make the cover plate break free from the restraint of the locking mechanism, thereby opening a directional pressure relief. However, the existing structure needs to break free from the restraint of the locking mechanism through the force of the explosion, and the locking mechanism (such as a latch, or a lock, etc.) will be broken and bounced open in the process, posing a threat to the surrounding personnel and equipment. And if the strength of the material used for the locking mechanism is too high, it is also easy to make the explosion-proof cover plate difficult to open. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a directional pressure relief explosion-proof energy storage container.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A directional pressure relief explosion-proof energy storage container comprises an energy storage box body, wherein the top of the energy storage box body is open; a plurality of pulling guide rods are passed through and fixed to the upper part of the energy storage box body, and the two ends of the pulling guide rods pass through the energy storage box body and are slidably connected to sliding beams at the exposed parts, and the sliding beams are connected to the energy storage box body through a tension structure; one of the sliding beams is hingedly connected to a left cover plate disposed on the top of the energy storage box body, and the other sliding beam is hingedly connected to a right cover plate disposed on the top of the energy storage box body.

[0007] As a further improvement, a rain eyebrow is formed on the top side of the right cover plate to cover the gap where the left cover plate and the right cover plate abut.

[0008] As a further improvement, the pulling guide rods are arranged along the length direction of the energy storage box, are at the same height and are parallel to each other.

[0009] As a further improvement, the free ends of the left cover plate and the right cover plate are both formed with thickened extrusion portions.

[0010] As a further improvement, the tension structure is a tension spring.

[0011] As a further improvement, the left cover plate and the right cover plate are hingedly connected at the middle of the sliding beam, and the left cover plate and the right cover plate are formed with a limiting portion higher than the hinged connection.

[0012] The beneficial effects of the utility model are:

[0013] The utility model allows the explosion to occur in the energy storage container. When the left cover plate and the right cover plate are pushed open, due to the shape of the extrusion part, the lower contact end of the extrusion part squeezes the left cover plate and the right cover plate to both sides. In order to adapt to this deformation, the sliding beam slides outward on the pulling guide rod, and then the left cover plate and the right cover plate can be smoothly opened, so that the explosion energy in the energy storage container is discharged upward, so that the energy can be released. Under the action of the pulling guide rod and the mounting arm, the upper opening of the energy storage container is pulled to prevent the upper part of the energy storage container from opening to both sides under the impact, further restricting the explosion energy to spray upward. The rain eyebrow plays a role in shielding the gap between the extrusion parts, thereby preventing rainwater from entering. Under the action of the tension spring, the two extrusion parts are tightly fitted in the working state, so the sealing is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention is further described with reference to the accompanying drawings, but the contents in the accompanying drawings do not constitute any limitation to the present invention.

[0016] Figure 2 This is a schematic diagram of the front structure of a directional pressure relief explosion-proof energy storage container. DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and examples.

[0018] Example 1

[0019] like Figure 1-Figure 2 A directional pressure relief explosion-proof energy storage container shown includes an energy storage box body 1, a pulling guide rod 2, a sliding beam 3, a tension structure 4, a left cover plate 5, a right cover plate 6, a thickened extrusion part 7, a rain eyebrow 8, a limit part 9 and a mounting arm 10.

[0020] The pulling guide rod 2 passes through the upper part of the energy storage box 1 and is exposed at both ends. There are multiple pulling guide rods 2, which are arranged parallel to each other at the same height. An L-shaped mounting arm 10 concave inward is formed on the upper part of the energy storage box 1.

[0021] The two exposed ends of the pulling guide rod 2 are respectively slidably connected to the sliding beams 3, wherein the left sliding beam 3 is hingedly connected to the left cover plate 5, and the right sliding beam 3 is hingedly connected to the right cover plate 6. The sliding beam 3 is connected to the outer wall of the energy storage box 1 through a tension structure 4, i.e., a tension spring.

[0022] like Figure 1 As shown, in normal use, the left cover plate 5 and the right cover plate 6 are closed on the top of the energy storage box 1, and are in contact with each other through the tension structure 4 to prevent foreign objects from entering or someone accidentally pulling them open to cause danger.

[0023] When an explosion occurs inside the energy storage box 1, when the left cover plate 5 and the right cover plate 6 are opened, the ends of the left cover plate 5 and the right cover plate 6 collide with each other and rotate outward, and push each other, thereby overcoming the pulling force of the pulling structure 4, so that the sliding beam 3 slides outward first. After the left cover plate 5 and the right cover plate 6 are opened, the sliding beam 3 will be pulled inward by the pulling structure 4. The left cover plate 5 and the right cover plate 6 are opened to form an upward pressure relief port, so that the pressure is released upward to avoid damage to surrounding devices and personnel. In order to increase the pulling force that needs to be overcome when the left cover plate 5 and the right cover plate 6 are opened, the free ends of the left cover plate 5 and the right cover plate 6 are formed with a thickened extrusion portion 7. In order to prevent rain, the top side of the right cover plate 6 is convex to form a rain eyebrow 8 that covers the gap at the junction of the left cover plate 5 and the right cover plate 6.

[0024] Further, such as Figure 1 As shown, in order to prevent the left cover plate 5 and the right cover plate 6 from flipping downward when opened and hitting the surrounding personnel, the left cover plate 5 and the right cover plate 6 are hingedly connected in the middle of the sliding beam 3, and the left cover plate 5 and the right cover plate 6 are formed with a limiting portion 9 higher than the hinged connection.

[0025] The tension structure 4 is a tension spring.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
