Description

Technical Field

[0001] The utility model relates to a positioning structure, and more specifically, to a 1E-level storage battery anti-seismic installation monomer and an installation system thereof. Background Art

[0002] Safety level 1E stands for safety level electrical equipment for nuclear power plants. Safety level electrical equipment must undergo strict quality appraisal and meet special technical conditions and installation requirements.

[0003] At present, there is no perfect installation system design that can meet the seismic requirements of 1E-class batteries in the industry. The simple solution of tightening the battery with left and right beams is generally used to fix the battery. Improving the stability of the battery during installation and use is one of the difficulties in battery installation. The important reason is that the rationality and safety of battery installation will affect the service life of the battery, and it can also avoid the occurrence of some safety accidents. Among them, seismic resistance is a key issue that needs to be considered in the storage of 1E-class batteries.

[0004] At present, there is no unified standard for battery mounting brackets in the battery industry. For Class 1E batteries with strict seismic registration requirements, the industry generally adopts a simple solution of clamping the battery with left and right beams, which cannot completely fix the battery and is not very reliable.

[0005] In view of this, the present application aims to provide a 1E-level seismic mounting system for batteries that can reliably position the batteries on six sides to meet stringent seismic resistance requirements. Summary of the invention

[0006] The utility model overcomes the deficiency that the existing battery positioning schemes adopted in the industry are not sufficient to reliably position the battery, and provides a 1E-level battery seismic installation system that can reliably position the battery on six sides to meet the stringent seismic grade requirements.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A 1E-class battery anti-seismic installation monomer comprises a side column and a plane reinforcement structure. The plane reinforcement structure is arranged on the side column at equal intervals along the height direction of the side column. The battery is arranged between adjacent reinforced plane structures. Limiting columns are arranged between adjacent side columns on the left and right sides and the rear side of the battery. Limiting plates fitting the battery are fixedly connected to the limiting columns and the plane reinforcement structure. A positioning ring plate is arranged on the front side of the battery. The positioning ring plate is provided with a limiting step edge extending to the inner edge. The limiting step edge fits the outer edge of the top cover of the battery. The positioning ring plate is fixedly connected to the side column or the limiting column by fasteners.

[0009] The present application provides a mounting unit for mounting batteries. Specifically, a mounting space for a plurality of batteries arranged vertically is constructed by side columns and a plane reinforcement structure. The batteries are placed in a flat position. The present application reliably places the batteries. Specifically, limiting columns are set on the left and right sides and the rear side of the batteries, and the limiting columns are connected between the corresponding side columns, so as to limit the position of the batteries. The mounting unit provides an entry space for the batteries on the front side, and the batteries are placed into the mounting unit from the front side. After the installation is completed, the battery units are also positioned in the front direction by the positioning ring plate. The surfaces of the batteries that are arranged on the limiting columns and the plane reinforcement structure and are in contact with the surfaces of the batteries are thus reliably positioned on the six sides of the batteries, and the pressure on the batteries in contact with the outside is reduced, thereby reducing the probability of the batteries being damaged. During the vibration process, there is no relative movement between the batteries and the mounting unit. When the mounting unit is reliably positioned, the safety of the batteries is guaranteed.

[0010] Preferably, the plane reinforcement structure includes longitudinal beams on the left and right sides, a middle cross beam, a rear cross beam and a plurality of short square tubes, the two ends of the longitudinal beams are respectively connected to the two side columns, the two ends of the middle cross beam and the rear cross beam are fixedly connected to the middle and rear ends of the longitudinal beams, and the short square tubes are connected between the middle cross beam and the rear cross beam. The above structure provides a specific implementation structure of the plane reinforcement structure.

The two ends of the U-shaped tube are fixedly connected to the corresponding side column by welding. In addition to providing corresponding strength, the U-shaped tube also provides space for wiring. The wires and signal lines led out of the battery extend along the U-shaped tube and enter the side column from the wire hole, and are pulled out from the side column.

[0012] Preferably, the U-shaped tube is provided with a plurality of reinforcing accessories, which are arranged at the opening of the U-shaped tube, and the reinforcing accessories are provided with positioning holes for positioning the positioning ring plate. The reinforcing accessories provide positioning space for the positioning ring plate while reinforcing the planar reinforcing structure, and the positioning ring plate also covers the opening of the U-shaped tube, thereby preventing the wires and signal lines from being exposed.

[0013] Preferably, the limiting column is arranged horizontally.

[0014] Preferably, the limit column is in an "X" shape, with one end of the limit column being fixedly connected to the side column and the other end being fixedly connected to the horizontal reinforcement structure. The "X"-shaped limit column has good strength performance in the horizontal and height directions, and the triangular shape of its ends respectively fitting the side column and the horizontal reinforcement structure is conducive to the transmission of conductive force and better maintains the overall strength of the seismic installation unit.

[0015] Preferably, each location of the installation unit is fixedly connected by welding.

The trapezoidal support frame can expand the projection area of ​​the bottom in the direction of gravity, and the center of gravity of the device is less likely to escape from the range of the projection area during vibration, thereby preventing the device from tipping over.

DETAILED DESCRIPTION

[0029] The present disclosure is further described below in conjunction with the accompanying drawings and embodiments.

[0030] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0031] Example:

[0032] A 1E-class battery anti-seismic installation monomer, such as Figure 1 As shown, it includes a side column 1 and a plane reinforcement structure 2, and the side column 1 is arranged in the vertical direction. Along the height direction of the side column 1, the plane reinforcement structure is arranged on the side column 1 at equal intervals, and the battery is arranged between adjacent reinforced plane structures. The side column 1 and the plane reinforcement structure 2 form a three-dimensional structure. The three-dimensional structure is defined as having three directions of front and back, left and right, and height, and six faces. On the left and right sides and the rear side of the battery, a limiting column 3 is arranged between adjacent side columns 1. The limiting column 3 includes a first column 8 arranged along the length direction and a second column 9 arranged along the width direction. Among them, the first direction is the left and right direction, and the width direction is the front and back direction. A limiting plate 4 that fits the battery is fixedly connected to the limiting column 3 and the plane reinforcement structure 2. The space formed by the limiting plate 4 between two adjacent plane reinforcement structures is open on the front side for inserting the battery. In some embodiments, the volume of the space is the same as the volume of a battery, and in other embodiments, a vertically arranged limit plate 4 is provided in the middle of the space, thereby dividing the space into two equal-sized sub-spaces, each of which is adapted to the volume of a battery. Similarly, there are also other equal division methods such as three-part and four-part, which are not listed one by one in this application.

[0033] like Figure 5As shown, a positioning ring plate 5 is provided on the front side of the battery, and the positioning ring plate 5 is provided with a limiting step edge 6 extending to the inner edge, and the limiting step edge 6 is in contact with the outer edge of the top cover of the battery, and the positioning ring plate 5 is fixedly connected to the side column 1 or the limiting column 3 by fasteners. Among them, the battery includes a top cover and a shell, and the distance from the top cover to the other end of the battery is longer than the length of the other sides. Therefore, by installing the battery in the form of inserting the corresponding surface of the top cover first, the center of gravity of the battery can be effectively lowered, thereby obtaining better anti-seismic ability.

[0034] like Figures 2 to 4 As shown, in some embodiments, the plane reinforcement structure includes longitudinal beams 21 on the left and right sides, a middle cross beam 10, a rear cross beam 22 and a plurality of short square tubes, the two ends of the longitudinal beam 21 are respectively connected to the two side columns 1, the two ends of the middle cross beam and the rear cross beam 22 are fixedly connected to the middle and rear ends of the longitudinal beam 21, and the short square tubes are connected between the middle cross beam and the rear cross beam 22. The above structure provides a specific implementation structure of the plane reinforcement structure. The overall strength of the plane reinforcement structure is provided by the middle cross beam and the short square tubes connected to the middle cross beam. A U-shaped tube 12 is provided on one side of the plane reinforcement structure 2 between adjacent batteries near the battery top cover. In some embodiments, the openings of the U-shaped tubes 12 with adjacent plane reinforcement structures 2 on both sides face the front side of the battery, while the openings of the U-shaped tubes 12 with the plane reinforcement structure 2 on only one side face the rear side. The side column 1 is a hollow tube body with open ends, and the side column 1 is provided with a through hole 13 corresponding to the U-shaped tube 12, and the short square tube 11 is connected between the middle cross beam 10 and the U-shaped tube 12. The two ends of the U-shaped tube 12 are fixedly connected to the corresponding side column 1 by welding. In addition to providing corresponding strength, the U-shaped tube 12 also provides space for wiring. The wires and signal lines drawn from the battery extend along the U-shaped tube 12 and enter the side column 1 from the wire hole 13, and are pulled out from the side column 1. The U-shaped tube 12 also has a wire hole 13 on the front side. As for the connection position of each short square tube 11 connected to the middle cross beam 10, there are many implementation methods, including but not limited to equal spacing arrangement, wide setting in the middle and close laying on both sides.

[0035] Among them, Figure 1 As shown, the U-shaped tube 12 is provided with a plurality of reinforcing attachments 14, which are arranged at the opening of the U-shaped tube 12, and the reinforcing attachments 14 are provided with positioning holes 15 for positioning the positioning ring plate 5. The reinforcing attachments 14 provide positioning space for the positioning ring plate 5 while reinforcing the planar reinforcing structure, and at the same time, the positioning ring plate 5 also covers the opening of the U-shaped tube 12, thereby preventing the wires and signal lines from being exposed.

[0036] The limiting column 3 has a variety of implementations. In some embodiments, the limiting column 3 is horizontally arranged; in other embodiments, the limiting column 3 is in an "X" shape, and a portion of the end of the limiting column 3 is fixedly connected to the side column 1, and a portion is fixedly connected to the horizontal reinforcement structure. The "X"-shaped limiting column 3 has good strength performance in the horizontal and height directions. The triangular shape of its ends, which are respectively fitted with the side column 1 and the horizontal reinforcement structure, is conducive to the transmission of conductive force and better maintains the overall strength of the seismic installation unit.

[0037] In some embodiments, various locations of the installation unit are fixedly connected by welding; in other embodiments, various locations of the installation unit are connected by fasteners; in other embodiments, adjacent plate columns of the installation unit are riveted.

[0038] The present application provides a mounting unit for mounting batteries. Specifically, a mounting space for a plurality of batteries arranged vertically is constructed by side columns 1 and a plane reinforcement structure. The batteries are placed in a flat position. The present application reliably places the batteries. Specifically, the limiting columns 3 are arranged on the left and right sides and the rear side of the batteries. The limiting columns 3 are connected between the corresponding side columns 1, thereby limiting the position of the batteries. The mounting unit provides an entry space for the batteries on the front side. The batteries are placed into the mounting unit from the front side. After the installation is completed, the battery units are also positioned in the front direction by the positioning ring plate 5. The surfaces of the batteries that are arranged on the limiting columns 3 and the plane reinforcement structure 2 and that are in contact with the surfaces of the batteries are thus reliably positioned on the six sides of the batteries, and the pressure on the batteries when in contact with the outside is reduced, thereby reducing the probability of the batteries being damaged. During the vibration process, there is no relative movement between the batteries and the mounting unit. When the mounting unit is reliably positioned, the safety of the batteries is guaranteed.

[0039] like Figure 5 , 6 As shown, a 1E-class battery anti-seismic installation system includes a plurality of 1E-class battery anti-seismic installation units arranged along the length direction as described above, adjacent 1E-class battery anti-seismic installation units are fitted and fixedly connected by connecting strips 16, and the connecting strips 16 are arranged at equal intervals along the fitting gap formed by the fitting of the 1E-class battery anti-seismic installation units. The above structure connects two units through the connecting strip 16, and a plurality of connecting strips 16 are arranged along the joint formed by the splicing, and are connected by welding, and the area of ​​the connecting part of the connecting strip 16 and the two units is the same.

[0040] The 1E-class battery anti-seismic mounting unit is fixedly connected to the base plate 17. The base plate 17 is welded to the embedded parts or the vibration table to prevent the entire device from leaving the ground.

[0041] In some embodiments, a trapezoidal support frame 18 is also included, and the trapezoidal support frame includes a plurality of horizontal support plates 19 and a trapezoidal plate 20 fixedly connected to the rear side of the 1E-class battery anti-seismic installation unit, the trapezoidal plate 20 is narrow at the top and wide at the bottom, and the bottom is fixedly connected to the base plate 17, and the horizontal support plate 19 is fixedly connected to adjacent trapezoidal plates 20. The trapezoidal support frame 18 can expand the projection area of ​​the bottom in the direction of gravity, and the center of gravity of the device is less likely to escape from the range of the projection area during vibration, thereby preventing the device from tipping over.

[0042] In some embodiments, the installation system further includes a fire extinguishing box, which contains fire extinguishing liquid. The fire extinguishing box is fixedly connected to the top of the 1E-class battery anti-seismic installation unit. The fire extinguishing box is provided with a partition plate, which divides the fire extinguishing box into a plurality of sub-chambers. The partition plate is provided with damping holes, which allow the exchange of fire extinguishing liquid between adjacent sub-chambers. The partition plate is arranged at an angle. In addition to providing a fire extinguishing function, the structure can also exist as a vibration reduction damper, and the vibration transmitted from the rigid structure of the installation system can be eliminated by the liquid flowing between different sub-chambers through the damping holes. The inclined partition plate has a damping and shock absorbing effect on both transverse waves and longitudinal waves.
