Description

Technical Field

[0001] This utility model belongs to the field of battery box technology. Specifically, it relates to a liquid-cooled integrated battery box. Background Technology

[0002] In oil and gas extraction and mining, mobile energy storage devices are deployed in conjunction with photovoltaic, diesel generators, and wind power to form mobile energy storage power sources. These sources can power critical equipment such as downhole ventilation fans, oil and gas extraction pumps, instrument room computers, heating, lighting, and air conditioning. These scenarios involve highly complex engineering projects. The construction cycle for a single oil and gas well at a depth of 2000-3000 meters is generally about one month. A single operational platform typically handles 1-4 wells, forming a construction team that relocates after approximately 1-4 months of operation.

[0003] Construction projects in oil and gas and mining operations often involve 5-10 relocations, transportations, hoistings, installations, and commissionings per year, which differs significantly from conventional industrial and commercial energy storage scenarios. Among these, the battery box structure of the battery module is most significantly affected. Existing battery box structures are prone to fastener detachment during transportation due to shaking, affecting the secure holding of the batteries within the casing. This can lead to battery movement and collisions within the casing, causing malfunctions. Utility Model Content

[0024] Example:

[0025] See attached Figures 1-4 A liquid-cooled battery integrated case includes an integrated case cover 1, which comprises a top cover and four side panels. The integrated case cover 1 is integrally processed, reducing the connection between the top cover and the side panels and improving overall stability. The bottom of the integrated case cover 1 is provided with reinforcing ribs 2, and reinforcing ribs 2 are vertically arranged on the sides of the four side panels. The integrated case cover 1 is detachably connected to the base via a screw structure. Several threaded holes are provided on the reinforcing ribs 2, and threaded holes are also provided on the base at positions corresponding to the threaded holes on the reinforcing ribs 2 of the integrated case cover 1. The screws are used to fix the integrated case cover 1 to the base, forming a battery pack housing. The battery pack 3 is formed by integrally stacking multiple batteries, and the bottom is fixed inside the housing by thermally conductive polyurethane adhesive.

[0026] To further enhance the load-bearing capacity of the battery pack casing, L-shaped steel 4 is welded under the base, effectively supporting the battery pack 3. L-shaped steel 4 is welded to the bottom of each of the four sides of the base. Adjacent L-shaped steel 4 are further connected at the four corners of the base by fasteners. The fasteners are right-angle fastening steel plates 5 with threaded holes. At the two corners at the front end of the base, the right-angle fastening steel plates 5 and adjacent L-shaped steel 4 form a right angle. Threaded holes are provided on both right-angle sides of the right-angle fastening steel plates 5, and corresponding threaded holes are also provided on the L-shaped steel 4. Screws are used for fixing. When the right-angle fastening steel plates 5 are fixed to the L-shaped steel 4 at the front end of the base, the screws are arranged horizontally, i.e., evenly distributed along the length of the L-shaped steel 4 at the front end of the base. Compared to the vertical screw fixing method used in the prior art, the horizontal screw fixing provides better vibration resistance during transportation. At the two corners of the rear end of the base, the right-angle fastening steel plate 5 also mates with the right angle formed by the two adjacent L-shaped steels 4. The right-angle fastening steel plate 5 is provided with threaded holes on the right-angled sides of the base, which are matched with the corresponding threaded holes on the L-shaped steels 4 on both sides of the base. The connection is fixed by screws. The right-angle fastening steel plate 5 is provided with threaded holes and positioning holes on the right-angled side of the rear end of the base, which are matched with the corresponding threaded holes and positioning holes on the L-shaped steels 4 at the rear end of the base. The connection is fixed by screws and positioning pins respectively.

[0027] Inside the battery pack casing, multiple batteries are stacked as a single unit. A limiting device further restricts the movement of the battery pack 3. Insulating side plates 6 are located on both sides of the battery pack 3, welded to the base to limit lateral movement. Several female buckles 7 are evenly distributed along the side direction at the top of the insulating side plates 6. The positions of the female buckles 7 on two insulating side plates 6 correspond one-to-one, and they are engaged by male buckles 9 at both ends of battery pressure strips 8. Multiple battery pressure strips 8, in conjunction with the insulating side plates 6, restrict the vertical displacement of the battery pack 3, thus providing a fixing function. This effectively solves the risk of loosening when the battery is subjected to mechanical impact and vibration, which could lead to increased welding resistance or open circuit in the power circuit. The battery pressure strips 8 are made of insulating material.

[0028] To ensure current flow between multiple batteries, a conductive busbar 10 is installed. The conductive busbar 10 is crescent-shaped. This design ensures both current carrying capacity and a safe distance between the conductive busbar 10 and the insulating side plate 6, allowing space for the battery vent valve and QR code. Based on the battery arrangement within the battery pack 3, adjacent batteries are connected sequentially via the conductive busbar 10, ensuring all batteries are connected through it. The specific connection structure is shown in the attached figure. Figure 2As shown. The conductive bus 10 has through holes at both ends for welding and positioning with the terminals on the battery. The conductive bus 10 also has two through holes in the middle for riveting and fixing temperature and voltage acquisition points. The specific acquisition method can be achieved using existing technology, which is readily available to those skilled in the art and will not be elaborated upon here.

[0029] The front end face of the integrated cover 1 is provided with a first mounting hole 11 and a second mounting hole 12. The first mounting hole 11 is used for the detachable installation of the data acquisition plate 13. Specifically, threaded holes are provided around the first mounting hole 11, and threaded holes are provided on the data acquisition plate 13 at corresponding positions. The detachable and fixed connection is achieved by screw engagement. The second mounting hole 12 is connected to the mounting bracket 14 in the same detachable manner. The mounting bracket 14 is used to connect the power socket, communication socket, and manual maintenance switch, etc. The data acquisition plate 13, as well as the power socket, communication socket, and manual maintenance switch, are all structures found in existing battery boxes. Their connection with the battery pack 3 is known to those skilled in the art and will not be described in detail here.

[0030] The top surface of the integrated box cover 1 is provided with a U-shaped reinforcing structure and a W-shaped reinforcing structure, as shown in the attached diagram. Figure 1 As shown, an uneven structure is formed on the top surface. The raised parts can withstand greater pressure and tension, thereby improving the strength of the integrated box cover 1 and reducing the material thickness cost.

[0031] The lifting hole 15 on the L-shaped steel 4 facilitates the lifting of the lifting tool during the transfer of this utility model.

[0032] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
