[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4 As shown, this utility model provides an auxiliary device for an intelligent battery management system of a marine power battery pack, including a base plate 5 and a lifting plate 9. A scissor bracket 14 is provided between the base plate 5 and the lifting plate 9. The lifting plate 9 is installed on the top of the scissor bracket 14. An iron sheet 15 is installed on the top surface of the base plate 5. An electromagnet plate 13 is installed on the bottom surface of the lifting plate 9. The distance between the electromagnet plate 13 and the iron sheet 15 is controlled by magnetic repulsion. A humidity sensor 6 is provided on one side of the base plate 5. A battery pack base 4 is fixedly connected to the top surface of the lifting plate 9. A temperature sensor 12 is fixedly connected to the bottom surface of the lifting plate 9. An integrated processor 8 is installed on one side of the battery pack base 4. A signal transmission line 7 connects the integrated processor 8 and the humidity sensor 6.

[0023] The specific settings and effects of the embodiment are as follows. Since the battery pack is installed in the power cabin at the bottom of the ship, the humidity in the cabin is relatively large, and water leakage may occur on the bottom plate of the cabin. The auxiliary device is used for properly rescuing and protecting the battery pack in an emergency. A humidity sensor 6 is arranged at the bottom of the device. When the humidity exceeds the normal threshold, the humidity sensor 6 detects a danger signal and transmits the signal to an integrated processor 8. The integrated processor 8 can detect the signal of the sensor and control the current flowing into the electromagnet plate 13, so as to control the electromagnetic force generated by the electromagnet plate 13, thereby enhancing the magnetic repulsion force generated by the electromagnet plate 13, and repelling each other between the electromagnet plate 13 and the iron sheet 15. The bottom plate 5 and the lifting plate 9 are lifted upward under the limiting action of the shear type support 14, and the buzzer alarm is triggered. The lifting plate 9 drives the battery pack base 4 and the battery pack away from the bottom plate, so as to avoid the safety accident caused by the premature immersion of the battery pack in the water, and provide more rescue time for the staff of the ship.

[0024] In addition, a plurality of heat dissipation fins are arranged at the bottom end of the lifting plate 9, which can quickly discharge the heat generated by the battery pack. A temperature sensor 12 is arranged at the bottom end of the lifting plate 9, which can detect the heat accumulated in the battery pack base 4 in time. When the battery pack base 4 and the battery pack work overheated, the electromagnet plate 13 will also increase the magnetic repulsion force, so as to lift the lifting plate 9 upward, but not trigger the buzzer alarm, thereby providing sufficient heat dissipation space.

[0025] Embodiment two is shown in Figs. Figure 1 and Figure 3 The outer side wall of the bottom plate 5 is fixedly connected with the box body 1. The box body 1 is provided with a heat dissipation fan 3 at one end and a heat dissipation hole at the other end. The two inner side walls of the box body 1 are fixedly connected with guide rails 2. The side wall of the lifting plate 9 is provided with guide grooves 11. The lifting plate 9 is slidingly connected with the outer side walls of the guide rails 2 through the guide grooves 11. The inner side walls of the guide grooves 11 are coated with lubricant. The shear type support 14 is provided with two fixed shafts 10 at one side and two movable shafts 16 at the other side. The two fixed shafts 10 are rotatably connected with the bottom plate 5 and the lifting plate 9 respectively. The two movable shafts 16 are slidingly connected with the bottom plate 5 and the lifting plate 9 respectively. One of the movable shafts 16 is slidingly connected at the gap between the bottom plate 5 and the iron sheet 15, and the other movable shaft 16 is slidingly connected at the gap between the lifting plate 9 and the electromagnet plate 13.

[0026] The whole embodiment achieves the effect that, in order to ensure the stability of the lifting plate 9 in the upward lifting process, the bottom plate 5 and the lifting plate 9 are connected through the shear type support 14, one end is supported through the fixed position fixed shaft 10, and the other end is supported through the movable shaft 16 which can be translated, meanwhile, the guide rail 2 is installed on the inner side wall of the box body 1, and the guide groove 11 is opened at the corresponding position of the lifting plate 9, the upward lifting of the lifting plate 9 is positioned through the guide rail 2, the lifting plate 9 moves along the vertical line during lifting, the stability of the upper battery pack and the battery pack base 4 is ensured, in order to further improve the heat dissipation effect of the battery pack, the heat dissipation fan 3 is installed on one side of the box body 1, when the temperature sensor 12 detects that the battery pack base 4 is overheated, the heat dissipation fan 3 is also transmitted with a signal, and the heat dissipation fan 3 is started, the cold air outside is introduced into the box body 1, and the heat dissipation hole is opened at the other end of the box body 1, so that the straight air duct is formed, and the heat exchange efficiency of the heat dissipation fin is improved.

[0027] The use method and working principle of the device are as follows: when water seeps, the humidity sensor 6 detects a danger signal and transmits it to the integrated processor 8, the integrated processor 8 controls the current flowing into the electromagnet plate 13 to be large, the magnetic repulsion force generated by the electromagnet plate 13 is enhanced, the electromagnet plate 13 and the iron sheet 15 repel each other, and the bottom plate 5 and the lifting plate 9 are lifted upward under the limiting action of the shear type support 14 and trigger the buzzer alarm.

[0028] When the battery pack is overheated, the temperature sensor 12 detects the heat accumulated in the battery pack base 4, and the magnetic repulsion force is increased, so that the lifting plate 9 is lifted upward, sufficient heat dissipation space is provided, and the heat dissipation fan 3 is started, the cold air outside is introduced into the box body 1, and the heat exchange efficiency of the heat dissipation fin is improved.

[0029] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms, and any skilled person in the art can change or modify the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification of the above embodiments made according to the technical essence of the present application still belong to the protection scope of the technical scheme of the present application.
