DETAILED DESCRIPTION

[0025] To make the purpose, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1-12As shown, the present invention provides a battery compartment waterproof group for a power-swap cabinet, comprising a power-swap cabinet 1 having a cylindrical outer shape and a digital display control panel. The outer side of the power-swap cabinet 1 is provided with a plurality of evenly distributed groups of battery insertion slots 2 along the vertical direction, each group having eight or more evenly distributed slots centered on the central axis of the power-swap cabinet 1. A central cavity 102 is provided at the central axis of the power-swap cabinet 1. A waterproof cover structure 3 capable of upward and downward expansion is provided on the outer side of the lower portion of the power-swap cabinet 1. A water level detection assembly 7 for detecting the water level is provided on the lower portion of the power-swap cabinet 1. A lifting rope weight structure 4 for lifting the waterproof cover structure 3 to provide waterproof protection for the power-swap cabinet 1 is provided within the central cavity 102. A liquid suction assembly 6 for extracting water therefrom is provided within the central cavity 102. The central cavity 102 not only accommodates key components such as the lifting rope weight structure 4 and the liquid suction assembly 6, but also provides space for the coordinated operation of the various components, while also serving as a connection and buffer in processes such as drainage and heat dissipation. When the water level detection component 7 detects that the water level has risen to a certain height, the waterproof cover structure 3 is pulled upward by the lifting rope weight structure 4. After the waterproof cover structure 3 is extended, it can wrap the entire battery swap cabinet 1, blocking the entry of external water, protecting the batteries in the battery insertion position 2 and the electrical components inside the battery swap cabinet 1 from water damage, playing a key role in waterproof protection.

[0027] The waterproof cover structure 3 includes a storage shell 301, which is arranged on the outside of the battery exchange cabinet 1. A storage chamber is formed between the inner wall of the storage shell 301 and the outer wall of the battery exchange cabinet 1. A telescopic cover 302 is arranged in the storage chamber, wherein the storage chamber plays a role in accommodating and protecting the telescopic cover 302, limiting the installation space position of the telescopic cover 302, and the outer contour of the telescopic cover 302 is wavy. An upper ring body 303 is provided on the upper side of the telescopic cover 302 to strengthen the structural strength of the upper side of the telescopic cover 302, and During the extension of the telescopic cover 302, as the part connected to the lifting rope weight structure 4, in order to be pulled upward, an upper edge plate 305 is provided on the outer side of the upper end of the battery exchange cabinet 1, and a sealing ring 304 is provided on the upper side of the upper edge plate 305. A sealing groove 306 for embedding and sealing with the sealing ring 304 is provided on the lower side of the upper edge plate 305. When the water level detection component 7 detects that the water reaches a certain height, the lifting rope weight structure 4 pulls the telescopic cover 302 to extend upward and realizes the embedding and sealing of the sealing ring 304 and the sealing groove 306. Through the above-mentioned specific structural design, the waterproof cover structure 3 can automatically activate the waterproof mechanism when the water level rises. Through the extension of the telescopic cover 302 and the cooperation of the sealing structure composed of the sealing ring 304 and the sealing groove 306, it provides effective sealing and waterproof protection for the battery exchange cabinet 1, ensuring the safe operation of the internal equipment of the battery exchange cabinet 1 in water-related conditions, avoiding equipment damage or failure due to water intrusion, and improving the safety and reliability of the battery exchange cabinet 1 in special environments such as humidity or floods.

[0028] The outer side of the battery exchange cabinet 1 is provided with two or more guide slots 104 uniformly distributed at equal angles with its central axis as the center. The extension direction of the guide slots 104 is consistent with the axial direction of the battery exchange cabinet 1. The inner wall of the upper ring body 303 is provided with a guide slider 315 corresponding to the guide slot 104. The guide slot 104 provides a sliding track for the guide slider 315 to limit its movement direction, ensuring that the upper ring body 303 drives the telescopic cover 302 to smoothly extend or retract along the axial direction of the battery exchange cabinet 1, preventing offset and jamming during the extension and retraction process, and ensuring the normal operation of the waterproof structure. The lifting rope weight structure 4 includes a lifting rope 403 arranged in each guide slot 104. The lifting rope 403 is a key component for transmitting power. After the water level rises and the mechanism is triggered, the pulling force is transmitted to the guide slider 315 by relying on the gravity of the weight block 404, thereby pulling the upper ring body 303 to drive the telescopic cover 302 to extend upward, achieving a waterproof seal. One end of the lifting rope 403 is fixedly connected to the corresponding guide slider 315, and the other end of the lifting rope 403 extends into the central cavity 102 and is fixedly connected to the weight block 404. The weight block 404 uses its own gravity to provide driving force for the extension of the telescopic cover 302.

[0029] Two parallel side panels 307 are provided on the side of the upper edge plate 305 near the sealing groove 306, and a locking block 308 is provided between the two side panels 307 through a hinge shaft 309. One end of the locking block 308 is in the shape of a triangular prism, and a torsion spring is provided between the hinge shaft 309 and the side panel 307. The other end of the locking block 308 is connected to a handle rod 310, and a push rod 311 is threadedly connected to the upper edge plate 305 for pushing the handle rod 310. The upper end of the push rod 311 passes through the upper surface of the upper edge plate 305 and is connected to a knob 312. A notch 313 is provided on the upper inner edge of the sealing ring 304, and a locking groove 314 is provided on the inner side of the sealing ring 304 for engaging with the locking block 308. This technical solution comprises a locking and limiting mechanism composed of side panels 307, a hinge shaft 309, a locking block 308, and a torsion spring. The locking mechanism utilizes the transmission of a push rod 311 and a knob 312 to achieve flexible control and secure positioning of the sealing ring 304. When the telescopic cover 302 is extended and the sealing ring 304 is inserted into the sealing groove 306, the operator rotates the knob 312 to push the push rod 311, causing the locking block 308 to rotate and engage the locking groove 314 of the sealing ring 304. The torsion spring maintains the locking mechanism, preventing the sealing ring 304 from loosening or shifting, ensuring a secure seal. To disassemble or adjust the telescopic cover 302, the knob 312 is rotated, causing the push rod 311 to disengage the handle 310 and the locking block 308 from the locking groove 314, unlocking the sealing ring 304. While ensuring the waterproof and sealing reliability of the battery exchange cabinet, the entire structure provides convenient manual intervention and adjustment methods, enhancing the practicality and maintenance convenience of the waterproof structure.

[0030] A charging structure 5 is provided on the top side of the battery exchange cabinet 1. The charging structure 5 includes an outer shell 501. A charger 502 is provided inside the outer shell 501. A fixed column 503 for fixedly supporting the charger 502 is provided inside the outer shell 501. A gap is formed between the battery exchange cabinet 1 and the outer shell 501. The upper edge plate 305 is provided on the lower edge of the outer shell 501. A first pulley 401 and a second pulley 402 for supporting the direction change of the lifting rope 403 are rotatably provided in the gap. The first pulley 401 is rotatably provided on the bottom side of the outer shell 501, and the second pulley 402 is rotatably provided on the top side of the battery exchange cabinet 1. Two electric telescopic rods 405 are provided on the top side of the central cavity 102. The push rod heads of the two electric telescopic rods 405 are arranged opposite to each other and are respectively fixedly connected to clamping blocks 406. The output end of the digital display control panel is electrically connected to the input end of the electric telescopic rod 405. In actual application, the outer shell 501, the charger 502 and the fixed column 503 in the charging structure 5 cooperate with each other to stably and safely provide power to the battery exchange cabinet 1. The gap between the battery exchange cabinet 1 and the outer shell 501 is used to arrange the first pulley 401 and the second pulley 402, which cooperate with the lifting rope 403 to optimize the traction path of the telescopic cover 302 and ensure the smooth operation of the telescopic cover 302 during extension and contraction. Under the control of the digital display control panel, the electric telescopic rod 405 and the clamping block 406 can clamp and release the weight block 404, similar to a control switch. While achieving efficient charging, the entire system ensures that when the water level of the battery exchange cabinet 1 changes, the telescopic cover 302 can be waterproofed and sealed in a timely and stable manner, comprehensively guaranteeing the normal operation of the battery exchange cabinet 1 and its internal equipment under various working conditions, thereby improving the reliability and practicality of the equipment. The battery insertion position 2 includes a battery insertion cavity 201 opened on the battery exchange cabinet 1, and a connecting groove 202 is opened in the battery exchange cabinet 1 below the battery insertion cavity 201. The connecting groove 202 and the battery insertion cavity 201 are connected to each other through a number of lower through grooves 203. A support bar 204 is arranged between two adjacent lower through grooves 203. The support bar 204 is raised and arranged on the inner bottom surface of the battery insertion cavity 201. The connecting groove 202 is connected to the central cavity 102 through more than three connecting holes 205.

[0031] The water level detection assembly 7 includes a plurality of water level detection chambers 701 opened at the lower part of the battery exchange cabinet 1 and evenly distributed around the central axis of the battery exchange cabinet 1, which are used to accommodate water and provide space for liquid level detection. Its evenly distributed design can sense the water level changes around the battery exchange cabinet 1 from multiple directions, thereby improving the comprehensiveness and accuracy of the detection. The lower ends of the water level detection chambers 701 are connected to each other through an annular liquid channel 702. The lower end of each water level detection chamber 701 is provided with a lower connecting channel 705 for connecting it to the outside, and a solenoid valve 706 capable of controlling its on and off is provided at the lower connecting channel 705. The upper end of each water level detection chamber 701 is provided with an upper connecting channel 704 for connecting it to the inside of the central cavity 102. A liquid level sensor 703 for detecting the height of the liquid level inside the water level detection chamber 701 is provided. The output end of the liquid level sensor 703 is electrically connected to the input end of the digital display control panel, and the output end of the digital display control panel is electrically connected to the input end of the solenoid valve 706. In actual applications, the water level detection component 7 realizes real-time, accurate detection and intelligent control of the water level around the power exchange cabinet 1 through the coordinated operation of various components. A plurality of evenly distributed water level detection chambers 701 cooperate with the annular liquid channel 702 to sense the external water level changes in all directions and keep the water level consistent; the liquid level sensor 703 monitors the liquid level in the water level detection chamber 701 in real time and transmits the data to the digital display control panel. When the water level reaches the preset threshold, the digital display control panel controls the solenoid valve 706 to close the lower connection channel 705 to prevent more water from entering; on the other hand, it sends a signal to the relevant systems such as the lifting rope weight structure to trigger the lifting rope 403 to pull the telescopic cover 302 upward to achieve waterproof sealing of the power exchange cabinet 1. The entire system has a high degree of automation and can respond to water level changes in a timely and accurate manner, providing reliable waterproof warning and protection for the battery swap cabinet 1 and its internal equipment, and improving the safety and stability of the equipment in humid or flooded environments.

[0032] The liquid suction component 6 includes a liquid pump 601 arranged on the outer shell 501, the liquid outlet of the liquid pump 601 is connected to the drain pipe 602, the liquid inlet of the liquid pump 601 is connected to one end of the suction pipe 603, and the other end of the suction pipe 603 passes through the central cavity 102 and the upper connection channel 704 in sequence and extends into the water level detection chamber 701. The output end of the digital display control panel is electrically connected to the input end of the liquid pump 601. The liquid suction component 6 realizes the active automatic extraction and discharge of the accumulated water in the water level detection chamber 701 through the coordinated cooperation of the liquid pump 601, the drain pipe 602, the suction pipe 603 and the digital display control panel. When the water level detection is completed in the water level detection chamber 701, or when the accumulated water needs to be discharged due to various reasons such as infiltration and damage, the digital display control panel sends a start signal to the liquid pump 601 according to the preset program or manual instruction. After the liquid pump 601 is started, suction is generated to pump the water in the water level detection chamber 701 through the suction pipe 603 and then discharge the water through the drain pipe 602.

[0033] A cooling fan 8 is provided at the bottom of the central cavity 102. A support fence 103 is provided on the inner side wall of the central cavity 102 above the cooling fan 8.

The output of the digital display control panel is electrically connected to the input of the cooling fan 8.

[0034] Working principle and technical effects of the present invention: Insert the battery into the battery insertion cavity 201 on the battery exchange cabinet 1, and place the battery on the support bar 204 to achieve stable support. When taking or placing the battery, operate directly on the battery insertion cavity 201. The water that penetrates into the battery insertion cavity 201 and the heat or water vapor generated by the battery can enter the connecting groove 202 through the lower through groove 203, and then enter the central cavity 102 through the connecting hole 205. When water accumulates around the battery exchange cabinet 1, the water level rises. When the liquid level sensor 703 in the water level detection component 7 detects that the water level reaches the set height, the solenoid valve 706 disconnects the lower connecting channel 705, the lifting rope weight structure 4 starts to work, and the electric telescopic rod 405 drives the clamping block 406 to loosen the clamping of the weight block 404. The weight block 404 falls due to gravity, pulling the lifting rope 403, and the lifting rope 403 drives the telescopic cover 302 to extend upward along the guide slide 104 through the guide slider 315. When the telescopic cover 302 rises to a certain position, the sealing ring 304 is embedded in the sealing groove 306 of the upper plate 305 to achieve a waterproof seal. At this time, the positioning block 308 is inserted into the positioning groove 314 of the sealing ring 304 to enhance the sealing effect. When water seeps into the central cavity 102, the liquid pump 601 is started. The liquid pump 601 extracts the water in the water level detection cavity 701 through the suction pipe 603, and the water is discharged from the battery exchange cabinet 1 through the drain pipe 602. At the same time, during daily use, the heat dissipation fan 8 works, and cooperates with the central cavity 102, the connecting groove 202, the lower through groove 203 and the connecting hole 205 to dissipate heat for all battery insertion positions 2, thereby reducing the internal temperature of the equipment and ensuring the normal operation of the equipment.
