Description

Technical Field

[0001] The utility model belongs to the technical field of mine battery cabinets, in particular to a mine reinforced battery cabinet. Background Art

[0002] With the widespread adoption and promotion of new energy technologies and energy conservation and emission reduction, the mining and construction vehicle industries have also actively engaged in electrification, exploring and implementing electrification, in addition to areas such as power grid transformation and electric vehicles. As a crucial component of current new energy systems, the design of battery cabinets impacts the performance of the entire system. Currently, most battery cabinets are simply frameworks, relying primarily on the performance of the battery packs themselves and the strength of the construction vehicle to withstand the harsh operating environment of mining, posing significant risks in long-term use. Existing battery packs produced by battery manufacturers are generally designed for passenger vehicles. Direct use in mining without prior treatment cannot withstand the high-frequency vibrations and high-density dust, easily leading to safety issues. Construction vehicle frames are often inherited from traditional gasoline-powered vehicles, without dedicated consideration for battery installation and protection. However, the large number of batteries in mining vehicles necessitates equipment suppliers design battery cabinets that address space, mounting, vibration damping, and protection issues to protect the batteries.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] The utility model discloses a reinforced battery cabinet for mining, such as Figure 1As shown, the T-shaped cabinet (which is installed between the two wheels of a mine car during actual use) includes two front and rear door panels 1, each of which is provided with a handle 2. The cabinet's skin is provided with several reinforcing ribs 14 arranged at an angle of 30° to 60° on each surface (except the bottom surface). The front and rear door panels 1 are also provided with a ventilation filter group 4. Cover panels 3 and observation windows 15 are provided on the other surfaces of the cabinet as needed. The observation window 15 is fixed to the skin by bolts. The cover panel 3 and the ventilation filter group 4 are equipped with hinges 12, buckles 11, and fixed angles 10. The two adjacent corners of the cover panel 3 are connected to the skin by hinges 12. Buckles 11 are provided on the other two corners of the cover panel 3. The skin is provided with fixed angles 10 at positions corresponding to the buckles 11. The cover panel 3 is opened and closed by whether the buckles 11 are engaged with the fixed angles 10. The lower part of the cover panel 3 is used to install equipment that requires frequent maintenance. The cover panel 3 is often opened, such as for adding water, coolant, oil, etc. A lifting ring 13 is provided on the top of the cabinet for lifting, and mounting beams 7 are provided on the bottom and both sides for positioning and assembling the cabinet. A high-voltage box 5 and a low-voltage box 6 are provided on the outside of the side skin adjacent to the door panel 1. The high-voltage box 5 is connected to the equipment in the cabinet through a power line, and the low-voltage box 6 is connected to the equipment in the cabinet through a control line. The high-voltage box 5 and the low-voltage box 6 separate the high and low voltages of the battery pack, which greatly improves the safety of the battery cabinet. The mounting beam 7 is detachable, flexible and convenient, and can adapt to various installation positions in on-site spaces. The movable cover 3 and the ventilation filter group 4 are easy to use, and there is no need to go down the cabinet for maintenance, which can save a lot of manpower and time costs for the maintenance of the battery cabinet. The door panel 1 plays a certain protective role for the battery cabinet against the harsh environment of the mine.

[0023] like Figure 2 As shown, multiple columns 17 and beams 18 are welded together to form a T-shaped frame for the battery cabinet. These columns 17 and beams 18 form multiple installation spaces 16 for mounting equipment within the cabinet. Multiple diagonal braces 19 are positioned between the columns 17 and beams 18 to reinforce the structure. All surfaces of the T-shaped frame, except the bottom, are covered with a sheath. Multiple angled panels 20 are positioned between the columns 17 and beams 18, reinforcing the cabinet's strength. The multiple installation spaces 16 (nine in this embodiment, but not limited to actual numbers and adjustable depending on the situation) are used to mount battery packs. The battery packs are connected and secured to the pre-reserved mounting holes in the beams 18, allowing for full front-accessible maintenance of the battery cabinet. Diagonal braces 19 and angled panels 20 are positioned based on mechanical simulation results, with welded locations at key locations (where stress concentration and damage are likely) to enhance the cabinet's strength. Wire tie rods 9 installed on each level and outside the cabinet ensure a more aesthetically pleasing and secure connection between the batteries and the equipment. Cable tie rods 9 of various sizes are designed at various locations inside and outside the cabinet (columns 17, crossbeams 18, and the outer skin) to secure the connecting cables between the batteries. The cabinet, composed of columns 17, crossbeams 18, diagonal braces 19, and angled panels 20, effectively protects the battery packs within, not only bearing the weight of the high-power battery packs but also dissipating the vibration and impact of mine roads.

[0024] like Figure 1 、 Figure 2 As shown, the grounding piles 8 arranged on both sides of the cabinet and each layer of the frame enable the equipment in the cabinet and the entire cabinet to be reliably grounded. The provision of multiple grounding piles 8 allows the electrical equipment to be grounded nearby, further improving the reliability of the battery cabinet.
