Description

Technical Field

[0001] The present invention relates to the technical field of energy storage cabinets, and in particular to an energy storage explosion-proof pressure relief shaft cabinet. Background Art

[0002] Industrial and commercial energy storage is a typical user-side application of distributed energy storage systems. Industrial and commercial energy storage systems usually serve enterprises, commercial buildings, and industrial parks. When the cabinet has high requirements for appearance and the cabinet door needs to be designed with a large arc, the interference distance will be even larger.

[0003] Among the existing patents, for example, "CN202420181084.2 A cabinet door structure for an industrial and commercial energy storage outdoor cabinet", although it solves the problem of combining cabinets, if the cabinet body is against the wall, the door cannot be opened normally, and the existing hinges need to be measured before installation to prevent the two components from deviating and affecting use. As can be seen, existing hinges have high pre-installation measurement requirements, which often increases the difficulty of installation. The control requirements for industrial and commercial energy storage systems are not as strict as those for large-scale energy storage power stations. Currently, energy storage cabinets on the market are all equipped with pressure relief valves. Their function is to discharge the hydrogen to relieve the pressure after long-term operation, when the hydrogen concentration in the energy storage equipment gradually accumulates and increases. Publication No. CN114976466A discloses an energy storage device with explosion-proof pressure relief function. It discloses a technical solution that continuously ventilates and timely discharges the hydrogen in the energy storage device to prevent explosions inside the energy storage device. However, simply discharging this hydrogen can easily lead to internal deflagration of the energy storage cabinet if the pressure rises rapidly. If the structural strength is insufficient to withstand the explosion pressure, the entire energy storage cabinet may explode, causing significant losses and casualties. Therefore, it is often necessary to install an explosion vent panel on the energy storage cabinet. The explosion vent panel is usually installed on the top of the cabinet and occupies a certain height and area, which has certain limitations on usage scenarios. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an energy storage explosion-proof pressure relief shaft cabinet to solve the problems raised in the background technology.

[0005] In order to achieve the above-mentioned purpose of the invention, the present invention provides an energy storage, explosion-proof and pressure-relief rotating shaft cabinet, comprising a cabinet body and a cabinet door arranged on the cabinet body, the top of the cabinet door is provided with an upper nylon shaft sleeve, the upper nylon shaft sleeve includes an upper shaft, the cabinet body is provided with an upper hole that cooperates with the upper shaft, the diameter of the upper hole is larger than the diameter of the upper shaft, the bottom of the cabinet door is detachably provided with a lower nylon shaft sleeve, the lower nylon shaft sleeve includes a lower shaft, the bottom of the cabinet body is provided with a bottom plate, the bottom plate is provided with a rectangular limit groove that cooperates with the lower shaft, the rectangular limit groove allows the lower shaft to move away from or close to the cabinet body, and a reset limit member is provided in the rectangular limit groove, and the reset limit member is connected to the inner side wall of the cabinet body away from the rectangular limit groove through a spring.

[0006] Furthermore, the side of the rectangular limiting groove close to the cabinet body is an arc-shaped fixed side wall, and the side of the reset limiting member facing the arc-shaped fixed side wall is a movable arc-shaped side wall.

[0007] Furthermore, the lower nylon sleeve is provided with four mounting holes, the cabinet door includes a door frame, and is threadedly connected to the door frame through the four mounting holes, and the upper nylon sleeve is fixedly connected to the door frame.

[0008] Furthermore, when the spring is in a normal state, the center line of the upper shaft coincides with the center line of the lower shaft. After the interior of the cabinet is pressurized, the spring is in a compressed state. At this time, the cabinet door compresses the spring under the action of pressure, so that the cabinet door and the cabinet are separated and the pressure is released.

[0009] Furthermore, the width of the reset limiting member is less than or equal to the width of the rectangular limiting groove.

[0010] Furthermore, there are two cabinet doors, and the two cabinet doors are connected to the cabinet body in the same manner.

[0011] Furthermore, the opening angle of the two cabinet doors is 90 degrees.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This application solves the problem that the explosion-proof plate in the prior art is usually installed on the top of the cabinet, occupies height and area, and has certain limitations on usage scenarios by arranging a reset limiter and a spring in the rectangular limit groove. When the cabinet is subjected to excessive pressure, a channel for explosion relief is generated by compressing the spring. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the invention, not all of them. The embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0030] like Figure 1-15As shown, an energy storage, explosion-proof, and pressure-relieving rotating shaft cabinet comprises a cabinet body 1 and a cabinet door 3 mounted on the cabinet body 1. The top of the cabinet door 3 is provided with an upper nylon sleeve 14, which includes an upper shaft 15. The cabinet body 1 is provided with an upper hole that mates with the upper shaft 15, and the diameter of the upper hole is larger than that of the upper shaft 15. The bottom of the cabinet door 3 is detachably provided with a lower nylon sleeve 5, which includes a lower shaft 11. The bottom of the cabinet body 1 is provided with a base plate 4, which is provided with a rectangular retaining groove 6 that mates with the lower shaft 11. The rectangular retaining groove 6 allows the lower shaft 11 to move away from or toward the cabinet body 1. A reset limiter 9 is provided in the rectangular retaining groove 6, which is connected to the inner wall of the rectangular retaining groove 6, away from the cabinet body 1, via a spring 8.

[0031] Specifically, the cabinet door 3 can be opened 90 degrees and can be flush with the wall 2 after opening. After the cabinet door 3 is opened 90 degrees, its outer wall can be flush with the outer wall of the cabinet body 1, which will not expand the overall floor space.

[0032] The nylon sleeve with the upper nylon sleeve 14 is mounted on the upper shaft 15, and the nylon sleeve with the lower nylon sleeve 5 is mounted on the lower shaft 11. By providing the nylon sleeve, the resistance to rotation can be increased, and when the cabinet door 3 is opened or closed, it is not easy for the cabinet door 3 to swing, providing sufficient damping;

[0033] By providing a rectangular limit groove 6, the lower nylon sleeve 5 can be away from the cabinet 1 to form an explosion relief channel. Specifically, a reset limiter 9 and a spring 8 are provided in the rectangular limit groove 6. When the pressure inside the cabinet 1 is not large, the reset limiter 9 is supported to clamp the lower shaft 11 under the action of the spring 8. When the pressure inside the cabinet is too large, the spring 8 is compressed to leave an explosion relief channel. The pressure of the spring 8 can be set according to the size of the interior of the cabinet 1. When a certain pressure is met, the spring 8 is compressed or fully compressed.

[0034] During installation, first install the upper nylon sleeve 14, stand the cabinet door 3 upright to the installation position, and then insert the lower shaft 11 with the lower nylon sleeve 5 through the door frame 13 into the rectangular limit groove 6, specifically between the reset limit piece 9 and the arc-shaped fixed side wall 7. The lower shaft 11 is cylindrical, and the arc-shaped fixed side wall 7 and the movable arc-shaped side wall 10 are fitted with the outer wall of the lower shaft 11 to position the lower shaft 11. After positioning, fix the lower nylon sleeve 5 on the door frame 13 with screws to complete the installation of the cabinet door 3.

[0035] In some embodiments, the side of the rectangular limiting groove 6 close to the cabinet 1 is an arc-shaped fixed side wall 7 , and the side of the reset limiting member 9 facing the arc-shaped fixed side wall 7 is a movable arc-shaped side wall 10 .

[0036] Specifically, during normal operation, the lower shaft 11 is upright. At this time, the arc-shaped fixed side wall 7 and the movable arc-shaped side wall 10 are in contact with the outer wall of the lower shaft 11 to ensure its normal operation. If the internal pressure is too large, the lower shaft 11 is pushed by the pressure to compress the spring 8 to form an explosion relief channel.

[0037] In some embodiments, four mounting holes 12 are further provided on the lower nylon bushing 5 , and the cabinet door 3 includes a door frame 13 , which is threadedly connected to the door frame 13 through the four mounting holes 12 , and the upper nylon bushing 14 is fixedly connected to the door frame 13 .

[0038] Specifically, four mounting holes 12 are provided on the lower nylon shaft sleeve 5 . The lower nylon shaft sleeve 5 can be installed on the door frame 13 by passing screws through the four mounting holes 12 .

[0039] In some embodiments, when the spring 8 is in a normal state, the center line of the upper shaft 15 coincides with the center line of the lower shaft 11. After the interior of the cabinet body 1 is pressurized, the spring 8 is in a pressurized state. At this time, the cabinet door 3 compresses the spring 8 under the action of pressure, so that the cabinet door 3 and the cabinet body 1 are separated and the pressure is released.

[0040] Specifically, under normal conditions, the spring 8 is partially compressed, and can support the lower shaft 11 at this time. If the internal pressure of the cabinet 11 increases, the lower shaft 11 will be pushed to compress the spring 8, thereby forming an explosion relief channel. Since the diameter of the upper hole is larger than the diameter of the upper shaft 15, the upper shaft 15 can be tilted at a certain angle after the spring 8 is compressed. In addition, since a nylon sleeve is provided on it, the nylon sleeve itself also has a certain elasticity and can support a certain angle of tilt. In other implementations of this embodiment, the upper hole can also be a square structure, so that the upper shaft 15 can be away from or close to the cabinet 1. After the spring 8 is compressed, it can be better tilted at a certain angle.

[0041] In some embodiments, the width of the reset limiting member 9 is less than or equal to the width of the rectangular limiting groove 6 , so as to better limit the position of the reset limiting member 9 and allow it to move inside the rectangular limiting groove 6 .

[0042] In some embodiments, there are two cabinet doors 3 , and the two cabinet doors 3 are connected to the cabinet body 1 in the same manner, which can open a larger area and facilitate operations in the cabinet body 1 .

[0043] Furthermore, the opening angle of the two cabinet doors 3 is 90 degrees, which does not take up too much space and allows the cabinet doors 3 to be opened normally.

[0044] Compared with the prior art, the present invention has the following advantages:

[0045] The present application provides a reset limiter 9 and a spring 8 in the rectangular limit groove 6. When the cabinet 1 is subjected to excessive pressure, a channel for venting explosion is generated by compressing the spring 8. This solves the problem that the explosion-proof plate in the prior art is usually installed on the top of the cabinet, occupies height and area, and has certain limitations on usage scenarios.

[0046] The technical solutions of the present invention have been described above in conjunction with specific embodiments. However, it should be noted that the above descriptions are merely for the purpose of explaining the solutions of the present invention and are not to be construed in any way as limiting the scope of protection of the invention. Based on the explanations herein, those skilled in the art can conceive of other specific embodiments of the present invention or equivalent replacements without inventive effort, and these will fall within the scope of protection of the present invention.
