DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-2 In this embodiment, a heat dissipation mechanism of a ship container lithium battery pack includes a box body 1, and a heat dissipation net 2 that can discharge the heat inside the box body 1 is fixed in the top wall and the bottom wall of the box body 1. Heat dissipation holes are opened in the two heat dissipation nets 2. Mounting holes are opened at the upper and lower ends of the box body 1. The two heat dissipation nets 2 are fixed in the mounting holes by bolts. The filter net can filter dust and smoke in the air to prevent them from entering the box body 1 and polluting the interior, thereby affecting the normal operation of the equipment. A cooling box 3 is fixed on the left side of the box body 1, and a sealing door is hinged on the left side of the cooling box 3 to prevent dust from entering the cooling box 3 and polluting the water quality, affecting the fluidity of the water, and making the refrigeration effect worse. A warehouse door 4 is hinged on the right side of the box body 1, and a cooling component 5 that penetrates the inner cavity of the box body 1 is fixed on the rear side wall of the inner cavity of the cooling box 3.

[0023] It should be noted that the cooling component 5 includes a water storage tank 501 fixed to the rear side wall of the inner cavity of the cooling box 3, a water injection pipe is fixed on the front of the water storage tank 501, and a water outlet pipe is fixed on the left side of the water storage tank 501. The water inside the water storage tank 501 can be replaced by setting the water injection pipe and the water outlet pipe. A water pump 502 located on the right side of the water storage tank 501 is fixed to the rear side wall of the inner cavity of the cooling box 3. A water pumping pipe 503 is connected between the water inlet of the water pump 502 and the water storage tank 501. The water outlet end of 2 is connected with a circulating water pipe 504 which penetrates the partition 8 and is connected with the right side of the water storage tank 501. The circulating water pipe 504 is distributed in a serpentine shape. When the condensing sheet 505 is refrigerated, the cooling speed of the water can be accelerated, so that the heat dissipation effect on the battery module 9 is better, and the water is prevented from being heated again by the heat of the battery module 9 during the reflux process, resulting in the cooling component 5 being unable to cool the battery module 9. The front of the circulating water pipe 504 is fixed with a condensing sheet 505 located in the inner cavity of the partition 8.

[0024] Furthermore, a working box 6 is fixed on the top of the box body 1, a driving mechanism 7 is fixed inside the working box 6, a partition 8 is fixed to the rear side wall of the inner cavity of the box body 1, a battery module 9 is fixed on the front of the partition 8, and a fixed box 10 is fixed to the bottom of the box body 1.

[0025] In this embodiment, the battery module 9 is cooled by air and water respectively through the driving mechanism 7 and the cooling component 5, so as to achieve the purpose of rapid cooling and heat dissipation and better heat dissipation effect.

[0026] See also Figure 3-4 In order to achieve the purpose of rapid heat dissipation, the driving mechanism 7 in this embodiment includes a servo motor 701 fixed to the box body 1, and the output shaft of the servo motor 701 is fixed with an active bevel gear 702, and the left side of the bottom of the active bevel gear 702 is meshed with a driven bevel gear 703. A connecting rod 704 that penetrates the box body 1 is rotatably connected between the working box 6 and the fixed box 10. The upper and lower ends of the connecting rod 704 are rotatably connected to the working box 6 and the fixed box 10 through the installation bearings. The installation bearings can support the rotation so that the equipment can operate normally, and can also reduce friction and extend the service life of the equipment. Four transmission components 705 are rotatably connected to the connecting rod 704.

[0027] It can be understood that the four transmission components 705 are composed of a first transmission wheel, a second transmission wheel and a transmission belt. The first transmission wheel is fixedly connected to the connecting rod 704, and the axis of the second transmission wheel is fixed to the output rod 7073. The outer surfaces of the first transmission wheel and the second transmission wheel are connected with a transmission belt. The first transmission wheel and the second transmission wheel are provided with a transmission groove that matches the conveyor belt. By setting the transmission groove, the tightness of the conveyor belt can be limited to ensure that the first transmission wheel and the second transmission wheel can transmit better and will not idle, resulting in the inability of the entire equipment to transmit and operate. The top wall and the bottom wall of the box body 1 are fixed with two groups of mounting frames 706, and each group of mounting frames 706 is movably connected with a displacement component 707 fixed to the transmission component 705.

[0028] Furthermore, the displacement assembly 707 includes a movable frame 7071 movably connected to the mounting frame 706, and the mounting frame 706 is provided with a sliding channel adapted to the left and right sides of the movable frame 7071. The inner cavity of the movable frame 7071 is meshed with a half gear 7072, and the half gear 7072 is meshed with the racks on the front and rear sides during rotation, so that the movable frame 7071 is driven to displace left and right, and the cooling fan 708 is further driven to displace, thereby blowing and cooling the battery module 9. An output rod 7073 is fixed at the axis of the half gear 7072, and the upper right output rod 7073 is fixed at the axis of the driven bevel gear 703. By being fixed to the driven bevel gear 703, the upper right output rod 7073 can be driven to rotate synchronously when the driven bevel gear 703 rotates, so that the other three transmission assemblies 705 can operate normally, thereby prompting the displacement assembly 707 to displace left and right.

[0029] In addition, the two output rods 7073 on the left are rotatably connected to the inner cavity of the box body 1 through fixed bearings, and the two output rods 7073 on the right are rotatably connected to the inner cavities of the working box 6 and the fixed box 10 respectively through ball bearings.

[0030] It is also necessary to say that cooling fans 708 are fixed on the opposite sides of the upper and lower displacement components 707. The displacement component 707 can drive the cooling fan 708 to perform large-scale air blowing and cooling of the battery module 9. A fixing block is fixed on the side of the cooling fan 708 close to the displacement component 707. The cooling fan 708 is fixed to the movable frame 7071 through the fixing block. While ensuring the stability of the cooling fan 708, it can be driven by the displacement component 707 to perform all-round air blowing and cooling of the battery module 9, thereby improving the heat dissipation effect.

[0031] In this embodiment, the transmission component 705 is driven by the servo motor 701, and the transmission component 705 transmits the rotational force to the displacement component 707, so that the cooling fan 708 is driven by the displacement component 707 to move left and right, and the battery module 9 is cooled by blowing air over a large area, thereby achieving the purpose of rapid heat dissipation and better heat dissipation effect.

[0032] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0033] The working principle of the above embodiment is:

[0034] After the battery module 9 is turned on, the driving mechanism 7 and the cooling component 5 are started, the output shaft of the servo motor 701 drives the active bevel gear 702, the active bevel gear 702 drives the driven bevel gear 703, the driven bevel gear 703 drives the output rod 7073 at the bottom, the output rod 7073 makes the half gear 7072 and the movable frame 7071 mesh, and at the same time, the rotation force of the driven bevel gear 703 is transmitted to the other three displacement components 707 by the transmission component 705 and the connecting rod 704, so that the four displacement components 707 start to move left and right at the same time, and the cooling fan 708 will also be driven to move left and right to blow and dissipate the battery module 9. At the same time, the water pump 502 will transport water to the circulating water pipe 504, and the circulating water pipe 504 will be cooled by the condensing sheet 505, so that the temperature of the partition 8 is low, which further promotes the temperature of the battery module 9 located on the partition 8 to drop, play a role in heat dissipation, complete the heat dissipation of the battery module 9, achieve the purpose of rapid cooling, and have a good heat dissipation effect.
