Description

Technical Field

[0001] This utility model belongs to the field of battery technology, and in particular relates to a shock-resistant bracket for a 1E-class battery. Background Technology

[0002] A battery bracket is used for battery installation and serves to protect the battery. For example, a battery bracket disclosed in CN203157900U includes two side plates, with a connecting plate for connecting to a vehicle frame fixed to the rear end of each side plate. A base plate with multiple grooved protrusions is welded between the side plates; a support rod is welded between the two connecting plates.

[0003] In scenarios with extremely high safety requirements, such as nuclear power plants, 1E-class batteries are core components of emergency power supplies, and their operational stability directly affects system safety. Currently, the commonly used battery seismic bracing in the industry typically involves simply placing the batteries on a bracket and relying on subsequently inserted plastic plates for insulation between the batteries. However, this approach has significant drawbacks: firstly, the plastic plates only provide basic insulation and cannot effectively limit the movement of the batteries, making them prone to swaying under vibration, resulting in poor seismic reliability; secondly, the subsequent insertion of the plastic plates is cumbersome and difficult, affecting assembly efficiency; and thirdly, the traditional bracket's iron frame lacks insulation between itself and the ground, and the accumulated static electricity over time can damage the internal structure of the batteries, shortening their lifespan. Therefore, designing a 1E-class battery seismic bracing system is essential. Utility Model Content

[0004] To address the problems of poor anti-vibration and anti-sway performance, cumbersome installation, and static electricity affecting battery life in existing battery anti-vibration brackets, this utility model provides a 1E-class battery anti-vibration bracket. Through integrated insulation design and split limiting structure, it achieves synergistic optimization of anti-vibration performance, ease of installation, and insulation protection.

[0005] This utility model is implemented as follows: a 1E-class battery anti-vibration bracket includes a support component, a load-bearing component, a limiting component, and an insulation component. The support assembly includes two symmetrically arranged columns and an iron base plate welded and fixed to the bottom of the columns; The insulating component is fixed to the bottom of the iron base plate; The supporting component includes a base support disposed between the two columns. The base support is welded from horizontally and vertically arranged square tubes and channel steel, and the upper surface of the channel steel is provided with an insulating pad layer. The limiting assembly includes an iron partition between the batteries, front stops fixed to both ends of the column, a front baffle welded to the front stops, and wooden boards and sheet metal pressure bars located at both ends of the two front stops and close to the battery side.

[0006] Preferably, the insulating component is a wooden base plate, which is attached to the bottom of the iron base plate.

[0007] Preferably, the insulating pad is an insulating rubber pad, which is adhered and fixed to the upper surface of the channel steel.

[0008] Preferably, elastic rubber pads are attached to both sides of the iron partition and the side of the wooden board near the battery.

[0009] Preferably, the bottom of the base is coated with insulating paint.

[0010] Preferably, the column is formed by bending and welding sheet metal parts.

[0011] Preferably, the sheet metal pressure bar is fixed to the column by fastening screws, and the fastening screws are fitted with anti-loosening nuts.

[0012] Preferably, the iron base plate has a round hole, and an insulating sleeve is installed in the round hole. The insulating sleeve is fixed by an external hexagonal screw.

[0013] Compared with related technologies, the 1E-class battery anti-vibration bracket provided by this utility model has the following beneficial effects: 1. This utility model uses a split limiting structure that combines partition separation, front baffle limiting and sheet metal pressure rod locking, combined with the buffering effect of elastic rubber pads, to effectively limit the swaying of the battery in the lateral and longitudinal directions, significantly reducing the probability of seismic failure; the setting of anti-loosening nuts further avoids loosening of the locking caused by vibration, and improves the structural stability.

[0014] 2. This utility model does not require subsequent insertion of plastic plates. The installation can be completed simply by placing the separator in the gap between the batteries, assembling the front baffle, front baffle, wooden board and sheet metal pressure rod in sequence and tightening the screws. This simplifies the assembly process and reduces the difficulty of operation. 3. This utility model achieves insulation between the bracket and the ground through a wooden base, insulation between the battery and the base through an insulating rubber pad, and insulation between the batteries through an iron partition and an elastic rubber pad. Combined with the design of the base's insulating paint and insulating sleeve, it forms all-round insulation protection, effectively blocking static electricity conduction and extending the working life of the battery. 4. All components of this utility model are manufactured using conventional materials and mature processes, resulting in a stable overall structure that is easy to mass-produce and has low maintenance costs.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figures 1 to 5 As shown, this utility model provides a seismic-resistant bracket for a Class 1E battery, used for supporting and fixing Class 1E batteries in nuclear power plants. The bracket includes a support assembly, a load-bearing assembly, a limiting assembly, and an insulation assembly.

[0019] The supporting components include two symmetrically arranged columns 1 and an iron base plate 2. The columns 1 are formed by bending and welding sheet metal parts, and their bottoms are welded and fixed to the iron base plate 2 as a whole. A wooden base plate 3 is attached to the bottom of the iron base plate 2 as an insulation component to achieve insulation between the support and the ground.

[0020] The supporting component is a base 4 located between two columns 1. The base 4 is welded from square tube 5 and channel steel 6. The bottom of the base 4 is coated with insulating paint. An insulating rubber pad is attached and fixed to the upper surface of the channel steel 6 as an insulating pad layer. The batteries 7 are placed on the insulating rubber pad in a 2×3 arrangement.

[0021] Limiting components: A gap is left between the batteries 7, and an iron partition 15 is installed in the gap; a front stop bar 8 is fixed on the column 1, and a front baffle 9 is welded and fixed on the side of the front stop bar 8 facing the battery 7. The front baffle 9 has a wooden board 10 and a sheet metal pressure bar 11 at both ends. Elastic rubber pads are attached to both sides of the iron partition 15 and the side of the wooden board 10 near the battery 7. There are 4 fastening screws 12 on each side of the column 1. The fastening screws 12 pass through the sheet metal pressure bar 11 and are fitted with anti-loosening nuts 13. The sheet metal pressure bar 11 is fixed by tightening the anti-loosening nuts 13.

[0022] Insulation reinforcement structure: The iron base plate 2 has a round hole, and an insulating sleeve 14 is installed in the round hole. The insulating sleeve 14 is fixed by an external hexagonal screw 16, which further enhances the overall insulation performance.

[0023] The working process and principle of this embodiment are as follows: During assembly, the base plate 4 is first installed between the columns 1, and then the batteries 7 are arranged in a 2×3 pattern on the insulating rubber pads of the base plate 4. Iron partitions 15 are inserted between adjacent batteries 7. Then, the front stop bar 8, the front baffle 9, the wooden board 10 with elastic rubber pads, and the sheet metal pressure bar 11 are installed in sequence. The sheet metal pressure bar 11 is locked with fastening screws 12 and anti-loosening nuts 13 to achieve longitudinal positioning of the batteries 7. Finally, the insulating sleeve 14 is fixed with hexagonal screws 16 to complete the assembly. In a vibration environment, the iron partition 15 restricts the lateral swaying of the batteries 7, the front baffle 9, the wooden board 10 and the sheet metal pressure bar 11 restrict the longitudinal swaying, and the elastic rubber pads buffer the vibration impact. The wooden base plate 3, the insulating rubber pads, the iron partition 15, the elastic rubber pads and the insulating sleeve 14 form all-round insulation to block electrostatic conduction.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
