[0002] In the current energy storage container industry, when assembling a container, the battery insertion box containing lithium-ion battery packs needs to be installed on the battery rack of the cluster according to the cluster design method. The battery insertion box itself is relatively heavy, and a forklift is required to fork the battery insertion box onto the battery rack belonging to the cluster, and then the battery insertion box is fixed to the battery rack by bolts to form a complete battery cluster. After the battery cluster is installed, it forms a complete large-capacity electrochemical energy storage container with other supporting facilities.

[0003] Adopting the insertion box assembly method in the related technology, since the connection between the battery insertion box and the mounting rack in the prior art is generally only fastened by several bolt assemblies on the front panel or the head, the constraint on the battery insertion box is insufficient, and there will also be a certain assembly gap between the battery insertion box and the battery rack for the convenience of taking and placing. Once transportation vibration, earthquake and other situations occur, the battery insertion box is likely to fall off the mounting rack, and the battery cells are prone to safety accidents such as spontaneous combustion, bulging or leakage under the action of collision and extrusion.

[0010] Further, two positioning pin shafts are provided on the tail baffle.

[0011] Further, the positioning pin shaft is detachably connected to the tail baffle.

[0012] Further, the positioning pin shaft includes an end mounting surface, an internal hexagonal hole in the mounting surface, a first taper pin slope, a second taper pin slope, a threaded surface, and a limit flange. The threaded surface is matched with a threaded through hole opened on the tail baffle and is limited by the limit flange.

[0013] Further, a support angle steel is fixed at the bottom of the column, and the support cross beam is located on the support angle steel.

[0014] Further, a guide plate is arranged on the side of the support cross beam.

[0015] The energy storage battery insertion box fixing device of the technical solution of the present utility model is arranged in an energy storage container and is used for fixedly installing the battery insertion box. The battery insertion box is placed on two support cross beams arranged in a group. After being inserted in place, the positioning pin shafts pre-installed at the tail baffle are matched with corresponding taper holes on the back of the battery insertion box, so as to realize three-phase limit fixation of the battery insertion box in directions other than the insertion direction, and avoid lateral and vertical displacement of the battery insertion box on the battery rack.

The plurality of groups of support cross beams 11 are arranged at equal intervals along the direction of the columns. The support cross beam 11 is fixedly connected to the column 12. Two support cross beams 11 are correspondingly arranged to set the battery insertion box respectively.

[0030] The side parts of the two support cross beams 11 are connected to the hexagonal riveted nuts 121 arranged on the column 12 through bolt assemblies 111. Support angle steels 113 are arranged at the bottoms of the two support cross beams 11. The support angle steels 113 are welded to the column 12. A tail baffle 13 is arranged at the middle part between the two support cross beams 11. The positioning pin shaft 3 is installed on the tail baffle 13. The positioning pin shaft 3 cooperates with the tapered hole 23 on the back of the battery insertion box 2 to fix and limit the insertion box.

[0031] A plurality of guide plates 112 are welded on the side part of the support cross beam 11. When the battery insertion box 2 is installed into the support cross beam 11, it can be aligned and positioned by these guide plates 112.

[0032] The front baffle 22 is fixed at the end of the support cross beam 11. Through holes are provided on the front baffle. After the battery insertion box 2 is installed in place, it is connected to the front baffle 22 through the flange surface bolts 221. The front baffle 22 is then connected to the hexagonal riveted nuts 222 arranged on the end face of the support cross beam 11 through the flange surface bolts 221. The openings on the front baffle 22 are all waist-shaped holes to facilitate fine adjustment of the position during installation.

[0033] In the embodiment of the present utility model, the fixing structure of the energy storage battery insertion box is arranged in an energy storage container and is used for fixedly installing the battery insertion box 2. By stacking a plurality of groups of support cross beams 11, a plurality of battery insertion boxes 2 are installed and supported to form a battery cluster.

[0034] During assembly, the battery insertion box 2 is inserted from one side of the battery rack 1 along the length direction of the support cross beam 11 through a forklift or a jib crane and other equipment and placed on two support cross beams 11 arranged in groups. The installation guide plates 112 on the opposite side end faces of the two support cross beams 11 assist in positioning the insertion and installation of the battery insertion box 2.

[0035] After being inserted in place, the positioning pin shaft 3 pre-installed at the tail baffle 13 welded to the middle of the two support crossbeams 11 cooperates with the corresponding tapered holes 23 on the back of the battery insertion box 2, realizing three-phase limit fixation of the battery insertion box 2 in directions other than the insertion direction, and preventing the battery insertion box 2 from undergoing lateral and vertical displacement on the battery rack 1.
