[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] Example 1

[0030] like Figures 1-3 As shown, an energy storage cabinet base is provided, which includes: a base frame 100, an inner beam 200 and a section head 210;

[0031] The inner side of the base frame 100 is provided with a first groove 110;

[0032] The inner beam 200 is disposed inside the base frame 100, and the cut head 210 is disposed at the end of the inner beam 200. The width of the cut head 210 is smaller than the width of the first groove 110. The cut head 210 is inserted into the first groove 110, and the edge of the cut head 210 is welded to the side wall of the first groove 110.

[0033] In the embodiment, the energy storage cabinet base comprises a base frame 100, an inner beam 200 and a section head 210. The base frame 100 is connected by four channel steels. The grooves of two opposite channel steels face the inner side of the base frame 100, and the grooves of the other two opposite channel steels face the outer side of the base frame 100. The groove facing the inner side of the base frame 100 is a first groove 110. The inner beam 200 comprises a plurality of horizontal beams and vertical beams, which are arranged perpendicularly in the inner part of the base frame 100. The section head 210 is arranged at the two ends of the vertical beam, and the section head 210 is arranged integrally with the vertical beam, and the width of the section head 210 is smaller than the width of the first groove 110 in the base frame 100. The two ends of the horizontal beam are right-angled ends, and the two right-angled ends of the horizontal beam are respectively welded to the back of the two channel steels with the grooves facing the outer side of the base frame 100. The horizontal beam and the vertical beam are respectively placed in the inner part of the base frame 100, and the section head 210 is inserted into the first groove 110, and the edge of the section head 210 is abutted with the edge of the first groove 110, so as to reduce the gap between the horizontal beam or the vertical beam and the first groove 110. When the section head 210 and the base frame 100 are welded, the horizontal beam and the vertical beam are more stably connected with the base frame 100, which is beneficial to improve the stability and durability of the base.

[0034] As shown in Figure 2 and Figure 3 In one embodiment, the side surface of the section head 210 is provided with an outer inclined surface 211, and the groove wall of the first groove 110 is provided with an inner inclined surface 111, and the outer inclined surface 211 is abutted with the inner inclined surface 111.

[0035] In the embodiment, the inner inclined surface 111 is arranged on the groove wall of the first groove 110, and the outer inclined surface 211 is arranged on the side surface of the section head 210. When the section head 210 is inserted into the first groove 110, the outer inclined surface 211 is abutted with the inner inclined surface 111, so that the contact between the section head 210 and the base frame 100 is more sufficient, which is beneficial to improve the stability of the welding between the section head 210 and the base frame 100.

[0036] As shown in Figure 2 and Figure 3 In one embodiment, the end of the inner beam 200 is provided with an abutting edge 212, the abutting edge 212 protrudes from the edge of the section head 210, and the abutting edge 212 is abutted with the edge of the first groove 110.

[0037] In this embodiment, the end of the inner beam 200 is provided with an abutting edge 212, and the abutting edge 212 protrudes from the edge of the cross head 210, so that when the cross head 210 is inserted into the first groove 110, the abutting edge 212 abuts the edge of the first groove 110, facilitating the welding of the abutting edge 212 and the base frame 100. At the same time, the abutting of the abutting edge 212 and the edge of the first groove 110 also facilitates the more rapid alignment and placement of the inner beam 200 and the base frame 100.

[0038] As shown in the drawings, in one embodiment, the base frame 100 further comprises an outer plate 130, the outer side of the base frame 100 is provided with a second groove 120, the outer plate 130 is arranged in the second groove 120, the edge of the outer plate 130 abuts the edge of the second groove 120, the side of the base frame 100 is provided with a matching hole 160, the outer plate 130 is provided with a first connecting hole 140, the matching hole 160 is arranged opposite to the first connecting hole 140, and the base frame 100 and the outer plate 130 are connected by a bolt passing through the first connecting hole 140 and the matching hole 160. Figure 4 In this embodiment, the groove towards the outside of the base frame 100 is the second groove 120, and the side of the base frame 100 is provided with a matching hole 160, which is towards the opening of the second groove 120. When the outer plate is installed on the opening edge of the second groove, the matching hole 160 is opposite to the first mounting hole 140 on the outer plate 130, and a bolt is sequentially passed through the first connecting hole 140 and the matching hole 160, the head of the bolt abuts the side of the outer plate 130 away from the base frame 100, and the shank of the bolt passes through the first connecting hole 140 and the matching hole 160, so that the outer plate 130 closes the second groove 120, avoiding the exposure of the second groove 120, which is conducive to reducing the corrosion rate of the base frame 100 and prolonging the service life of the base frame 100.

[0039] As shown in the drawings, in one embodiment, the base frame 100 further comprises an inner plate 150, the inner plate 150 is arranged in the second groove 120, the inner plate 150 is welded to the base frame 100, and the inner plate 150 is provided with a matching hole 160, which is opposite to the first connecting hole 140.

[0040] Figure 4

[0041] ​​In this embodiment, a mounting groove 121 is formed at the edge of the second groove 120, and an inner plate 150 is arranged in the mounting groove 121 and welded with the edge of the mounting groove 121. A matching hole 160 is formed in the inner plate 150, and the rod of a bolt passes through the matching hole 160 and the first connecting hole 140 in sequence. A nut is arranged on the side of the inner plate 150 facing the inner side of the second groove 120, and is screwed with one end of the bolt passing through the matching hole 160 and the first connecting hole 140. The inner plate 150 is welded on the base frame 100, so that the outer plate 130 is connected with the base frame 100 through the inner plate 150. In addition, the inner plate 150 is welded in the second groove 120, which can protect the second groove 120 from being directly exposed to the outside, reduce the contact with moisture and corrosive substances, and thus reduce the risk of rust. The inner plate 150 is welded with the channel steel, which also enhances the overall rigidity and stability of the base, so that the energy storage cabinet is more stable during loading and use.

[0042] As shown in Figure 1 In one embodiment, two groups of forklift holes 170 are formed on the base frame 100, and the two groups of forklift holes 170 are offset towards the side of the battery compartment in the energy storage cabinet.

[0043] In this embodiment, the battery compartment is the part with the heaviest weight in the energy storage cabinet. Therefore, the forklift holes 170 are designed to be offset towards the side of the battery compartment to provide better weight support and balance during transportation, thereby improving the overall stability.

[0044] As shown in Figure 1 In one embodiment, a fixing hole 180 is formed on the outer side of the base frame 100.

[0045] In this embodiment, a fixing hole 180 is formed on the outer side of the base frame 100, and the fixing hole 180 is used to fix the base frame 100 with the fixed point of the foundation by passing a steel cable through the fixing hole 180,

[0046] As shown in Figure 1 In one embodiment, a mounting hole 190 is formed on the top surface of the base frame 100, and the base frame 100 is connected with the cabinet body of the energy storage cabinet by passing a bolt through the mounting hole 190.

[0047] In this embodiment, the bolt passes through the mounting hole 190, so that the base frame 100 is connected with the cabinet body of the energy storage cabinet in a screwing form. Compared with the welding process, the base frame 100 and the cabinet body of the energy storage cabinet can be separated. When the cabinet body and the base frame have different colors, welding requires secondary spraying, and the base frame needs to be shielded during secondary spraying, which is difficult in process. The base frame can be sprayed separately and then installed by bolts.

[0048] AsFigure 5 As shown in the figure, in one embodiment, a wedge-shaped block 220 is also included, which abuts the bottom surface of the first groove 110, and an auxiliary hole 221 is provided in the interior of the wedge-shaped block 220, and a second through hole 1111 is provided in the bottom surface of the first groove 110, the auxiliary hole 221 is arranged opposite to the second through hole 1111, and a bolt is provided in the auxiliary hole 221 and the second through hole 1111, and the base frame 100 is connected to the foundation through the bolt.

[0049] In the embodiment, the bottom surface of the first groove 110 can have a region with a slope, and the wedge-shaped block 220 is used to fill the first groove 110 on the inner side of the channel steel. The wedge-shaped block 220 is welded on the inner side of the channel steel, especially those used to fill the slope, so as to change the bottom surface of the first groove 110 into a plane. When the base frame 100 is fixed to the foundation or the like through the bolt passing through the auxiliary hole 221 and the second through hole 1111, the main function of the wedge-shaped block 220 is to prevent the bolt from being loosened under stress. Because the bottom surface of the first groove 110 on the inner side of the channel steel has a slope, the bolt can be gradually loosened after being tightened due to the slope, and the wedge-shaped block 220 effectively prevents this situation by changing the slope into a plane.

[0050] As shown in the figure, Figure 1 In one embodiment, a notch 1112 is provided on the inner side of the base frame 100, and the notch 1112 is located above the auxiliary hole 221.

[0051] In the embodiment, the notch 1112 is located above the auxiliary hole 221, which facilitates technicians to use an electric tightening tool to quickly tighten the bolt in the auxiliary hole 221 through the notch 1112, and the torque can be accurately controlled, and the efficiency is higher and the reliability is stronger compared with manual tightening.

[0052] The technical features of the above embodiments can be combined in any manner. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present application.

[0053] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
