AI Technical Summary
When existing battery enclosures are used in the casting of T-beam hoppers, they cannot simultaneously achieve high heat dissipation and waterproof performance, posing a risk of electric leakage.
Design a battery protection box, which features a heat dissipation window on the side of the box and a ventilation and heat dissipation unit. Automatic heat dissipation and waterproofing are achieved by using a rotating heat dissipation plate and a water-expanding unit. The water-expanding unit drives the rotating heat dissipation plate to seal the box through a highly absorbent resin plate and a sliding plate.
It achieves good heat dissipation under normal conditions and automatically seals to prevent water leakage when exposed to water, reducing the risk of electric leakage. It has a simple structure and low cost, making it suitable for long-term outdoor use.

Abstract
Claims
1. A battery protection case comprising a case body, characterized by: The side of the enclosure has a heat dissipation window, and a ventilation and heat dissipation unit is connected inside the heat dissipation window. The ventilation and heat dissipation unit includes a hinge rod and several rotating heat dissipation plates arranged in parallel with each other. All rotating heat dissipation plates are rotatably connected to the enclosure and to the hinge rod. A heat dissipation gap is formed between adjacent rotating heat dissipation plates. A water-swellable unit is connected to the bottom wall of the enclosure. A top rod is rotatably connected between the water-swellable unit and the hinge rod.
2. The battery protection case of claim 1, wherein: The water-swellable unit includes a highly absorbent resin board and a sliding plate, with the highly absorbent resin board located between the sliding plate and the bottom wall of the box; the sliding plate is slidably connected to the box, and the top rod is rotatably connected between the sliding plate and the hinge rod.
3. A battery protection case according to claim 2, wherein: The number of top rods is multiple, and the number of hinge rods is equal to the number of top rods and corresponds one-to-one. The multiple hinge rods are spaced apart along the length direction of the rotating heat sink.
4. A battery protection case according to claim 3, wherein: The bottom wall of the box is provided with an installation groove, a highly absorbent resin board is connected to the installation groove, and the sliding plate is slidably connected to the installation groove.
5. A battery protection case according to claim 4, wherein: A drainage hole is provided between the bottom wall of the box and the bottom wall of the mounting groove, and a drainage groove is opened on the sliding plate to communicate with the highly absorbent resin board.
6. A battery protection box according to claim 2, characterized in that: A water-absorbing cotton is connected between the super absorbent resin board and the slide plate.
7. The battery protection case of claim 2, wherein: The ventilation and heat dissipation unit is also equipped with a mounting frame connected to the heat dissipation window. The mounting frame is fixedly connected with a number of rotating shafts that are equal to and correspond one-to-one with the number of rotating heat dissipation plates. The rotating heat dissipation plates are rotated in conjunction with the rotating shafts.
8. A battery protection case according to any one of claims 1-7, characterized in that: The side of the rotating heat sink is fixedly connected to a protrusion that fits against the adjacent rotating heat sink, and the protrusion is coaxially arranged with the rotating shaft.
9. A battery protection case according to claim 8, wherein: A sealing gasket that mates with a protrusion on an adjacent rotating heat sink is fixedly connected to the side wall of the rotating heat sink.
10. The battery protection case of claim 1, wherein: The aforementioned heat dissipation windows are provided on both the left and right sides of the enclosure.
