Further, an annular cavity 20 is arranged inside the fixing sleeve 1, a rotating ring 22 is rotatably connected inside the annular cavity 20, the top of the baffle plate 23 is fixed with the rotating ring 22 through a bonding part 24, the bonding part 24 can be made of a material which is easily melted by heat, such as soldering tin or glue, so that the baffle plate 23 is bonded at the bottom of the rotating ring 22, and the baffle plate 23 is placed inside the annular cavity 20.
In practical use, when the motor 12 drives the bevel gear ring 8 and the sealing cover 11 to rotate, the baffle 23 can be synchronously driven to rotate along with the sealing cover 11 in the annular cavity 20, however, when the battery body 21 is on fire, the temperature of the fixing sleeve 1 and the temperature of the rotating ring 22 rise, so that the bonding part 24 is melted, the baffle 23 bonded at the bottom of the rotating ring 22 falls off and falls on the top of the base 19 along the sliding groove 25 at the opening 26, the opening 26 on the sealing cover 11 is sealed by the baffle 23 at the moment, external air is prevented from entering the fixing sleeve 1 through the opening 26, the top end of the fixing sleeve 1 is sealed through the sliding plate 2, the whole inside of the fixing sleeve 1 is in a sealed environment at the moment, the external air is difficult to enter the inside of the fixing sleeve 1, and therefore, the inside of the fixing sleeve 1 is gradually in an anoxic state, which is beneficial to controlling the fire, achieve the purpose of fire extinguishing and is safer in actual use.
Besides, a one-way pressure relief component, such as a one-way valve, is arranged outside the sealing cover 11, so that air inside the sealing cover 11 can be discharged in one way through the one-way valve, and the excessive air pressure inside the sealing cover 11 is avoided.
As shown in fig. 5 to 10, a collar 9 is fixedly connected to the bottom of the bevel gear ring 8, the collar 9 is rotatably disposed on the outer side of the base 19, the ventilation slots 7 are disposed on the outer side of the collar 9, the number of the ventilation slots 7 is set to be plural, the ventilation slots 7 are distributed on the outer side of the collar 9 in an annular array, and the number of the ventilation slots 7 is preferably set to be four.
Furthermore, through vent holes 15 are formed in the outer side surface of the base 19, multiple sets of vent holes 15 are arranged, the multiple sets of vent holes 15 are distributed on the outer side of the base 19 in an annular array, the number of the sets of vent holes 15 is equal to the number of vent grooves 7 on the outer side of the collar 9, four sets of vent holes 15 are preferably arranged, and the overall length of each set of vent holes 15 is smaller than the length of the vent grooves 7; in addition, a sealing ring 16 is provided at the bottom of the base 19 to increase the sealing between the bottom of the base 19 and the contact surface.
In practical use, when the motor 12 drives the bevel gear 13 to rotate, the bevel gear 13 drives the bevel gear ring 8 and the lantern ring 9 at the bottom of the bevel gear ring to rotate, the lantern ring 9 is provided with the ventilation groove 7, and the base 19 is provided with a plurality of groups of ventilation holes 15 matched with the ventilation groove 7;
when the sliding plate 2 inside the fixing sleeve 1 slides upwards, the collar 9 is in the process of rotating and the ventilation slot 7 on the collar is staggered with the ventilation hole 15 on the base 19, so the ventilation hole 15 on the base 19 can be sealed through the collar 9, and the sealing ring 16 at the bottom of the base 19 improves the sealing property between the bottom of the base 19 and the contact surface, so that external air can only enter the fixing sleeve 1 through the opening 26 on the sealing cover 11 and the annular filter plate 10;
when the sliding plate 2 inside the fixed sleeve 1 slides downwards, the ventilation slots 7 on the lantern ring 9 are aligned with the ventilation holes 15 on the base 19 in the rotating process, and at the moment, air in the cavity inside the fixed sleeve 1 can be exhausted through two ways, namely through the annular filter plate 10 and the opening 26 on the sealing cover 11, and through the circular filter plate 18 and the ventilation holes 15 and the ventilation slots 7, and through the arrangement of the two exhaust paths, the flowing range of air flow inside the fixed sleeve 1 is favorably increased, more heat is taken, and the heat dissipation efficiency is also improved.
In conclusion, when slide 2 upwards slides and is in the stage of breathing in, ventilation groove 7 staggers with ventilation hole 15, lantern ring 9 can seal ventilation hole 15 this moment, it enters into fixed cover 1 inside through ventilation hole 15 to avoid the dust on bottom surface or the contact surface, thereby protect the battery, avoid the dust to get into and cause the influence to the use of battery, and when slide 2 moves down and is in the exhaust stage, ventilation groove 7 is corresponding with ventilation hole 15, fixed cover 1 inside gas can be discharged through ventilation hole 15 this moment, on the one hand, the radiating efficiency is increased, on the other hand can take out the dust of the inside bottom of equipment, thereby the inside clean and tidy of equipment has been kept, be favorable to battery body 21's work.
The working principle is as follows: when the slide plate 2 moves upwards so that outside air enters the inside of the fixed cover through the opening 26, the position of the opening 26 is changed along with the rotating seal cover 11, so that the opening 26 rotates along with the seal cover 11 to another position outside the other ring-shaped filter plate 10 in the process of moving downwards, so that the air in the fixed cover 1 is discharged through the opening 26 after changing the position; for example, when the bevel gear 13 rotates the bevel gear ring 8 by 0 to 45 ° relative to its initial state, the sliding plate 2 moves upward, and at this time, the external air is sucked into the fixing sleeve 1 through the opening 26 and the ring filter plate 10, and therefore, the air suction phase is performed in the range of 0 to 45 °, and when the bevel gear 13 rotates the bevel gear ring 8 in the range of 45 to 90 °, the sliding plate 2 moves downward, so that the gas inside the fixing sleeve 1 is discharged through the rotating opening 26, and therefore, the exhaust phase is performed in the range of 45 to 90 °, and since the air suction and the exhaust are not in the same range, the discharged heat is not sucked into the fixing sleeve 1 again, thereby facilitating the temperature reduction of the battery body 21 inside the fixing sleeve 1, and at this time, the discharged heat has enough time to be dissipated, and in addition, the air suction phase and the exhaust phase occur at different positions, the range of gas flow inside the fixing cover 1 is made wider and the flow time is made longer, so that the heat radiation effect to the battery body 21 can be improved.
