Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology, and in particular relates to a directional pressure relief explosion-proof energy storage container. Background Technology

[0002] With the continuous maturation of energy storage technology, energy storage devices and systems are also developing rapidly, especially with the increasing demand for energy storage power stations from both the grid and user sides. Integrating energy storage devices and systems within containers can prevent external environmental influences, ensuring their normal and stable operation. However, existing energy storage containers typically house battery packs. When these battery packs malfunction and the fire suppression system cannot adequately address the issue, they are prone to explosion under high temperature and pressure. Since the structure of existing energy storage containers is usually similar to that of ordinary containers, the pressure from an explosion can cause the container to rupture in all directions, damaging surrounding equipment and personnel, resulting in significant losses. A search revealed that patent application number 202323245553.7 discloses a directional pressure relief explosion-proof energy storage container, including an energy storage box body with an open top. Several traction guide rods pass through and are fixed to the upper part of the energy storage box body. The two ends of the traction guide rods pass through the energy storage box body and are slidably connected to sliding beams. The sliding beams are connected to the energy storage box body through a tension structure. A left cover plate covering the top of the energy storage box body is hinged to one of the sliding beams, and a right cover plate covering the top of the energy storage box body is hinged to the other sliding beam.

[0003] However, during actual use, the applicant discovered that the left and right cover plates are hinged and rotatably connected to the sliding beams on both sides. When the left and right cover plates are opened upwards under pressure, the large force exerted on them makes them prone to breaking at the hinge point, causing them to fly outwards. This makes the directional pressure relief explosion-proof design of the energy storage container unsafe and unreliable. Therefore, we propose a directional pressure relief explosion-proof energy storage container. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a directional pressure relief explosion-proof energy storage container, comprising an energy storage box body. The upper part of the energy storage box body has symmetrically arranged movable slots on both sides. A pressure relief window is located at the center of the top of the energy storage box body. A pressure guide seat is fixedly arranged along the edge of the top of the energy storage box body. A pressure guide slope is provided on the inner side wall of the pressure guide seat. A top cover is provided on the top of the energy storage box body. Guide columns are symmetrically fixedly connected to the bottom of the top cover. The lower end of each guide column extends movably into the movable slot and is fixedly connected to a connecting plate. A spring is sleeved on the guide column.

[0006] Preferably, the top of the pressure guide seat is provided with an arc-shaped rainproof protrusion.

[0007] Preferably, an arc-shaped protective groove is provided at the edge of the bottom of the top cover, and the arc-shaped protective groove is connected to the arc-shaped rainproof protrusion.

[0008] Preferably, a pressure-bearing protective plate is fixedly connected to the bottom of the top cover, and the guide column penetrates through the pressure-bearing protective plate.

[0009] Preferably, a plurality of guide posts on the same side are provided at equal intervals along the front-back direction, and the lower ends of the guide posts on the same side are fixedly connected by a connecting plate.

[0010] Preferably, the lower end of the spring abuts against the connecting plate, and the upper end of the spring abuts against the top of the moving groove.

[0011] This utility model has the following beneficial effects:

[0012] This utility model discloses a directional pressure relief explosion-proof energy storage container. Through the design of a pressure guide seat and a top cover, in the event of an explosion inside the energy storage container, the top cover is pushed upwards, separating from the pressure guide seat. This, in turn, causes the guide column and connecting plate to move upwards, compressing the spring. The pressure generated by the explosion is then directionally released upwards along the pressure guide slope between the pressure guide seat and the top cover. During this process, a pressure-bearing protective plate provides pressure protection for the top cover. After the pressure is released, the connecting plate, guide column, and top cover automatically return to their original positions under the elastic force of the spring, preventing damage to surrounding personnel and objects from an explosion. This makes the pressure relief and explosion-proof design of the energy storage container safer and more reliable. The combination of an arc-shaped rainproof protrusion and an arc-shaped protective groove effectively waterproofs the connection between the pressure guide seat and the top cover, preventing rainwater from entering the interior of the energy storage container from this connection point.

[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. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A directional pressure relief explosion-proof energy storage container includes an energy storage body 1. The upper part of the energy storage body 1 has symmetrically arranged movable slots 11 on both sides. A pressure relief window 12 is located at the center of the top of the energy storage body 1. A pressure guide seat 2 is fixedly installed along the edge of the top of the energy storage body 1. A pressure guide slope 21 is provided on the inner wall of the pressure guide seat 2. A top cover 3 is installed above the energy storage body 1. A pressure-bearing protective plate 7 is fixedly connected to the bottom of the top cover 3. Guide columns 5 are symmetrically fixedly connected to the bottom of the top cover 3, penetrating the pressure-bearing protective plate 7. The guide columns 5 on the same side extend along the front... Several guide posts 5 are evenly spaced at the rear. The lower end of the guide post 5 extends movably into the moving groove 11 and is fixedly connected to the connecting plate 6. The lower end of the guide post 5 on the same side is fixedly connected by the connecting plate 6. A spring 4 is sleeved on the guide post 5. The lower end of the spring 4 abuts against the connecting plate 6, and the upper end of the spring 4 abuts against the top of the moving groove 11. Through the pressure guide seat 2 and the top cover 3, when an explosion occurs inside the energy storage box 1, the top cover 3 can be pushed upward, causing the top cover 3 to separate from the pressure guide seat 2, and driving the guide post 5 and the connecting plate 6 to move upward, thus affecting the spring 4. During compression, the pressure generated by the explosion can be directionally released upwards along the pressure guide slope 21 between the pressure guide seat 2 and the top cover 3. During this process, the pressure-bearing protective plate 7 provides pressure protection for the top cover 3. After pressure release, under the elastic force of the spring 4, the connecting plate 6, guide column 5, and top cover 3 automatically return to their original positions downwards, preventing damage to surrounding personnel and objects from an explosion of the energy storage tank 1. This makes the pressure release and explosion-proof design of the energy storage tank 1 safer and more reliable. When an explosion occurs inside the energy storage tank 1, the pressure generated by the explosion... It can push the top cover 3 to move upward, so that the top cover 3 separates from the pressure guide seat 2. At this time, the pressure generated by the explosion can be pushed upward along the pressure guide slope 21 and directionally depressurized between the top cover 3 and the pressure guide seat 2. During this process, the upward movement of the top cover 3 can drive the connecting plate 6 to move upward through the guide column 5. The upward movement of the connecting plate 6 can compress the spring 4. After the pressure is depressurized inside the energy storage box 1, under the elastic force of the spring 4, it can drive the connecting plate 6 to move downward, and can drive the top cover 3 to move downward through the guide column 5, thus completing the automatic reset of the top cover 3.

[0022] The top of the pressure guide seat 2 is provided with an arc-shaped rainproof protrusion 22, and the bottom edge of the top cover 3 is provided with an arc-shaped protective groove 31. The arc-shaped protective groove 31 and the arc-shaped rainproof protrusion 22 are connected in cooperation. Through the cooperation of the arc-shaped rainproof protrusion 22 and the arc-shaped protective groove 31, the connection between the pressure guide seat 2 and the top cover 3 can be effectively waterproofed, preventing rainwater from entering the interior of the energy storage box 1 from the connection between the pressure guide seat 2 and the top cover 3. After the pressure guide seat 2 and the top cover 3 are closed, the arc-shaped rainproof protrusion 22 can be inserted into the arc-shaped protective groove 31. Through the cooperation of the arc-shaped rainproof protrusion 22 and the arc-shaped protective groove 31, the connection between the pressure guide seat 2 and the top cover 3 can be effectively protected from rain.

[0023] Working principle: When an explosion occurs inside the energy storage tank 1, the pressure generated by the explosion pushes the top cover 3 upward, separating it from the pressure guide seat 2. The pressure generated by the explosion then rises along the pressure guide slope 21 and is directionally released between the top cover 3 and the pressure guide seat 2. During this process, the upward movement of the top cover 3 drives the connecting plate 6 upward via the guide post 5. The upward movement of the connecting plate 6 compresses the spring 4. After the pressure inside the energy storage tank 1 is released, the spring force of the spring 4 drives the connecting plate 6 downward and, via the guide post 5, drives the top cover 3 downward, completing the automatic reset of the top cover 3. After the pressure guide seat 2 and the top cover 3 are closed, the arc-shaped rainproof protrusion 22 can abut into the arc-shaped protective groove 31. Through the cooperation of the arc-shaped rainproof protrusion 22 and the arc-shaped protective groove 31, the connection between the pressure guide seat 2 and the top cover 3 can be effectively protected from rain.
