Description

Technical Field

[0001] The present invention relates to the technical field of power exchange cabinets, and in particular to a moisture-proof power exchange cabinet for a logistics site. Background Art

[0002] Currently, a battery swap cabinet is a facility used to store and replace batteries of electric equipment (such as electric vehicles, electric forklifts, etc.). It allows users to quickly replace batteries when needed to improve the efficiency and endurance of the equipment. The battery swap cabinet is usually designed with a battery storage rack, a battery charging system, and a mechanized or automated device for battery replacement.

[0003] Regarding the above-mentioned related technologies, the inventor believes that the following defects exist: in order to prevent moisture inside the battery swap cabinet and affect battery charging and the use of the entire battery swap cabinet, dehumidifying and moisture-proof objects are added to the inside of the battery swap cabinet, such as quicklime, activated carbon, etc., which can absorb moisture and can be heated and dried for repeated use after absorbing moisture. However, since there is no heating device in the battery swap cabinet, staff can only collect the moisture manually frequently. As a result, most merchants choose to directly discard the moisture and replenish it with new ones because frequent collection and unified heating are not convenient enough, resulting in unnecessary waste of resources. In order to reduce maintenance costs, they even do not replenish moisture-absorbing objects, which is harmful to the equipment and users. Summary of the invention

The sliding block cooperates with the second movable groove to restrict the movement of the second fixed block, thereby preventing the movement of the second fixed block from being offset;

[0062] See also Figure 1 and Figure 8 , protective covers 25 are fixedly installed on both sides of the power exchange cabinet 1, and a maintenance door 26 is provided on one side of each protective cover 25. The protective cover 25 prevents external rain and moisture from entering the interior of the power exchange cabinet 1;

[0063] An air outlet is provided at the top of the inner cavity of each protective cover 25, and an air outlet pipe 27 is installed on each air outlet. A check valve is installed inside each air outlet pipe 27. The check valve prevents external water vapor from entering the interior of the protective cover 25 while not blocking the discharge of water vapor inside the protective cover 25.

[0064] See also Figure 2 A baffle 28 is fixedly installed inside each battery replacement slot 2, and each baffle 28 is provided with a plurality of ventilation holes for ventilation. The baffle 28 prevents the battery from accidentally colliding with the moisture-absorbing splint 301 during replacement.

[0065] Working principle: Set the interval time of each drying start of the servo motor 501 in advance. The drying time is that the servo motor 501 rotates forward after it is turned on, then stops for a period of time and then rotates in the reverse direction. The total time of forward and reverse rotation is one drying time. There will be a long interval between each time, so that the moisture absorption splint 301 can absorb moisture.

[0066] The servo motor 501 is a very mature existing technology. Through programming and the setting of the servo controller, the user can control the start and stop of the servo motor 501, and the rotation angle after starting can be set.

[0067] After the servo motor 501 is set, it is necessary to wait for a period of time to allow the moisture absorbing splint 301 to absorb the moisture. This waiting time needs to be set;

[0068] When the moisture absorbing clamping plate 301 is wet, the servo motor 501 is started, and the driving rod 502 rotates, so that the first bevel gear 503 drives the second bevel gear 504 to rotate, and finally the threaded column 505 rotates. The rotation of the threaded column 505 causes the push plate 9 threadedly matched therewith to move, and the push plate 9 pushes the moisture absorbing clamping plate 301 when moving, and pushes the moisture absorbing clamping plate 301 out of the connecting port;

[0069] When the pushing plate 9 pushes the moisture absorbing clamp 301, it will also push the first connecting plate 11 and the two pushing blocks 12, and push the first connecting plate 11 and the two pushing blocks 12 out from the adjacent pushing ports. In this way, before the moisture absorbing clamp 301 moves out of the battery swap slot 2, the pushing block 12 will first contact the third sliding bar 401, thereby pushing the third sliding bar 401 in advance, and the third sliding bar 401 is rotatably connected to the second sliding bar 303, so after being pushed, it will dock with the second sliding bar 303, so that the first sliding bar 302 can move back and forth with the moisture absorbing clamp 301 on the second sliding bar 303 and the third sliding bar 401 without being stuck. Because the connecting port has a width, the moisture absorbing clamp 301 has enough moving stroke, and the moisture absorbing clamp 301 will be pushed out only after the third sliding bar 401 docks with the second sliding bar 303;

[0070] After the third sliding bar 401 is pushed, the protection plate 402 will push the first limiting rod 18 to move the first limiting rod 18, thereby opening the blocked communication port, and allowing the moisture absorbing splint 301 to pass through the communication port;

[0071] After the third sliding bar 401 is docked with the second sliding bar 303, not only will the moisture absorbing clamp 301 be further pushed onto the third sliding bar 401, but the first contact switch 7 and the second contact switch 8 will also be in contact with each other, so that the controller 6 will heat the heating wire 403 when it is powered on. At this time, the moisture absorbing clamp 301 has moved to the side of the heating wire 403 and is waiting for heating.

[0072] When the push plate 9 moves, it will also move with the second connecting plate 24. The movement of the second connecting plate 24 will move the push spring, thereby pushing the second fixed block, and finally making the fourth contact switch 22 on the second fixed block contact with the third contact switch 21 on the first fixed block. The contact between the two will start the small motor 19, thereby allowing the fan blades 20 to rotate, so that airflow can be generated inside the power exchange cabinet 1, and the hot air from the internal battery charging can be sent into the protective cover 25 through the connecting port, which can not only speed up the drying speed of the moisture absorbing splint 301, but also cool the inside of the power exchange cabinet 1 to a certain extent. Finally, the hot air will be discharged from the outlet pipe 27, and the check valve will not block the internal air from flowing outward.

[0073] After the heating is completed, the servo motor 501 starts to reverse, so that the push plate 9 will pull the moisture absorbing splint 301 back to the original position to absorb moisture and continue to absorb. The first connecting plate 11 and the two push blocks 12 will also be retracted into the interior of the power exchange cabinet 1, and the third sliding bar 401 will lose its resistance. The two elastic bands 13 will pull the adjacent protective plates 402. Since all the protective plates 402 on the same side are fixed with the synchronization block 14, all the protective plates 402 on the same side will rotate, and finally the third sliding bar 401 will rotate and fit tightly against the outer shell of the power exchange cabinet 1. In conjunction with the pulling of the first limit rod 18, the sealing plate 15 can be pulled to the connecting port to seal and cover the connecting port to prevent external water vapor from entering the interior of the power exchange cabinet 1.

[0074] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
