Description

Technical Field

[0001] This utility model relates to the field of battery storage equipment technology, and in particular to a high-strength fiberglass battery underground box. Background Technology

[0002] With the development of new energy, long-distance pipelines and other fields, the demand for outdoor storage of batteries, as the core component of energy storage, is increasing. Underground storage has become one of the mainstream solutions due to its advantages such as saving ground space and avoiding external environmental interference. However, existing underground battery boxes have the following technical defects:

[0003] 1. Insufficient resistance to pressure and deformation: Most existing underground boxes adopt a flat box structure with no specific reinforcement design on the facade. Under the action of a 1.5-meter soil load (including lateral soil pressure), the facade is prone to bulging and the top and bottom are prone to sinking, which will cause the box to crack and damage the internal battery protection.

[0004] 2. Poor sealing performance, prone to leakage. Summary of the Invention

[0005] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a high-strength fiberglass battery underground box, which includes a box body and a box cover connected by connectors. Both the box body and the box cover are provided with corrugated reinforcing ribs to strengthen the box and enhance its compressive strength.

[0009] As a further improvement of this utility model, the sealing ring is made of EPDM rubber or hydrogenated nitrile rubber.

[0010] As a further improvement of this utility model, the inner sidewall of the box is provided with a number of mesh reinforcing ribs.

[0011] As a further improvement of this utility model, a number of mesh reinforcing ribs are provided on the inner side of the box cover.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] like Figures 1 to 6As shown, the high-strength fiberglass battery underground box of this utility model includes a box body 1 and a box cover 2 connected by connectors. Several corrugated reinforcing ribs 3 are provided on the outer side wall of the box body 1 and the outer side of the box cover 2 to strengthen the solidity and enhance the pressure resistance.

[0028] In this utility model, the four corners of the box body 1 and the box cover 2 are all provided with R10mm rounded corners; specifically, the interior of the box body is a truncated pyramid structure: the upper opening size is 860mm×810mm, the lower opening size is 805mm×755mm, the depth is 300mm, and the vertical slope angle is 5° to disperse lateral earth pressure. The 5° slope angle, combined with the corrugated reinforcing ribs (wave height 20mm), can disperse the lateral earth pressure to the entire box body, increasing the lateral pressure resistance of the vertical surface by more than 40%, and the deformation is ≤1.5mm under lateral pressure of 14.7kPa; the four corners of the box body 1 and the box cover 2 are all provided with R10mm rounded corners, and the rounded corners are locally thickened and reinforced (the wall thickness is increased to 8mm, which is 5mm higher than the wall thickness of the box body foundation) to reduce stress concentration. The R10mm thickened rounded corners reduce stress concentration and prevent cracking at the four corners, ensuring long-term use (5 The structural strength retention rate is ≥95%; the four facades of the outer wall of box 1 are provided with vertical wave-shaped reinforcing ribs with a wavelength of 150mm, a wave height of 20mm (protrusion height), and a rib thickness of 5mm (consistent with the foundation wall thickness of box 1). The peaks and troughs of the ribs are provided with R2mm rounded corners to improve the lateral pressure resistance of the facade.

[0029] In this utility model, the inner sidewall of the box body 1 and the inner side of the box cover 2 are provided with several mesh reinforcing ribs 3. Specifically, the ribs are 20mm high (protrusion height), 5mm wide, and the mesh spacing is 120mm×120mm. The roots of the ribs are provided with R3mm rounded corner transitions to enhance the top and bottom compressive strength, avoid local depressions, and make the top and bottom compressive bearing capacity ≥30kPa, far exceeding the design load of 1.5 meters of soil cover (16.7kPa). There is no depression or cracking after holding the load for 1 hour.

[0030] In this utility model, the box body 1 and the box cover 2 are made of fiberglass. The fiberglass SMC substrate contains ≥30% glass fiber (alkali-free glass fiber, diameter 10~13μm). The matrix resin is added with anti-hydrolysis and anti-UV additives to ensure weather resistance and corrosion resistance. Molding process parameters: temperature 135~145℃, pressure 15~20MPa, holding time 3~5min. The holding time for reinforcing ribs, rounded corners, and sealing grooves is extended to 5~6min to avoid bubbles and loose connections.

[0031] In this invention, the outer surfaces of both the box body 1 and the box cover 2 are coated with a 0.5mm polyurea coating to improve impact resistance.

[0032] In this invention, both the top edge of the housing 1 and the edge of the cover 2 are provided with integrally formed flanges 4, facilitating connection and secure installation. The flanges 4 on the housing are provided with annular sealing ring grooves 6 for installing the sealing ring. The grooves are 10mm wide and 5.8mm deep, with no breaks or burrs, and the verticality deviation of the groove walls is ≤0.1mm. The sealing rings are made of EPDM rubber or hydrogenated nitrile rubber, with a cross-sectional diameter of 8mm, a hardness of 60±5 Shore A, and a compression set ≤20% (70℃×24h), achieving IP68. Grade I waterproof; the flange 4 is provided with evenly distributed screw holes 7 for installing bolts, and the bolts are equipped with spring washers and nitrile rubber waterproof washers; specifically, the flange 4 is 10mm thick, 35mm wide, the flange flatness deviation is ≤0.2mm / m, and the surface roughness Ra is ≤6.3μm; the flange 4 is evenly distributed with screw holes 7: the screw hole 7 has a diameter of 6.5mm (suitable for M6 stainless steel bolts), the center distance of the hole is 10mm from the outer edge of the flange, the hole spacing is ≤150mm (at least 6 on each side, total number ≥24), to ensure uniform connection force; the bolts are equipped with spring washers and nitrile rubber waterproof washers, and the tightening torque is controlled at 15~20N・m to prevent loosening and water seepage from the screw holes.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
