[0033] See also Figure 1-3 As shown, the present invention is a device for multi-stage high-speed pulse fast charging of a lead-acid battery, comprising a shell 1. When in use, the lead-acid battery 100 is placed in the shell 1 for formation charging. When in use, a first module 2 and a second module 3 for spraying water to the outer wall of the lead-acid battery 100 are arranged on the inner wall of the shell 1. Then, during the charging formation stage, the first module 2 and the second module 3 are used to spray water to the outer wall of the lead-acid battery 100, and the water flow is used to take away the heat generated by the lead-acid battery 100 during the charging formation stage.

[0034] In order to better control the first module 2 and the second module 3 to spray water onto the outer wall of the lead-acid battery 100, and to facilitate the placement of the lead-acid battery 100 into the shell 1, a telescopic part A11 connected to the first module 2 and driving the first module 2 to move in the horizontal direction is provided on one opposite side wall of the shell 1, and a telescopic part B12 connected to the second module 3 and driving the second module 3 to move in the horizontal direction is provided on the other opposite side walls of the shell 1.

[0035] Specifically, the first module 2 and the second module 3 have the same structure; Figure 4 The first module 2 includes a strip substrate 20, and a plurality of water spray nozzles 23 are arranged at equal intervals along the length direction of one side of the strip substrate 20; in order to prevent the water flow sprayed by the water spray nozzle 23 from impacting the outer wall of the lead-acid battery 100 and then splashing to the top surface of the lead-acid battery 100, and to prevent the water flow sprayed by the water spray nozzle 23 from not flowing well along the outer wall surface of the lead-acid battery 100 during use; the present invention connects strip sponge blocks A21 and sponge blocks B22 to the edges of both sides of a surface of the strip substrate 20 on both sides of the water spray nozzle 23, respectively, and utilizes the sponge block A21 to prevent the water flow from impacting the outer wall of the lead-acid battery 100 and then splashing to the top surface of the lead-acid battery 100, and utilizes the sponge block B22 to promote the water flow to impact the outer wall of the lead-acid battery 100 and then flow downward along the outer wall surface of the lead-acid battery 100.

[0036] At the same time, in order to facilitate the support of the lead-acid battery 100 placed in the housing 1 during use, and to facilitate the control of the placement and removal of the lead-acid battery 100, such as Figure 6-7 A bearing mechanism for bearing the lead-acid battery 100 and controlling the up and down movement of the lead-acid battery 100 is also provided in the shell 1; the bearing mechanism includes a protrusion A13 provided on two opposite inner side walls of the shell 1, and a telescopic cylinder 130 that can be telescoped in the vertical direction is connected to the bottom side of the protrusion A13, and the ends of the two telescopic cylinders 130 are connected to a bearing frame 16; when in use, the lead-acid battery 100 is placed on the bearing frame 16, and the bearing frame 16 is driven to move up and down in the vertical direction by controlling the action of the telescopic cylinder 130.

[0037] In order to ensure the vertical stability of the carrier 16 during operation, bumps B15 are further provided on the inner side walls of the shell 1 located on both sides of the bump A13. The bottom side of the bump B15 is connected to the guide telescopic rod 131, and the end of the guide telescopic rod 131 is connected to the carrier 16.

[0038] Similarly, in order to avoid splashing water from impacting the outer wall of the telescopic section of the telescopic cylinder 130 during use, causing possible damage to the telescopic cylinder 130, such as Figure 5 A protective sleeve 131 is provided on the bottom side of the protrusion A13, and the telescopic cylinder 130 is arranged in the protective sleeve 131; a wiper ring 132 is provided at the bottom end of the protective sleeve 131 to cooperate with the telescopic section of the telescopic cylinder 130, and a plurality of drainage holes 133 are provided on the wiper ring 132.

[0039] When in use, the carrier frame 16 is provided with a detection system for detecting whether a lead-acid battery 100 is placed on it and detecting the size of the lead-acid battery 100; the detection system is connected to the controller, and the controller is connected to the telescopic part A11 and the telescopic part B12; and then when in use, the telescopic part A11 and the telescopic part B12 are controlled to extend to a corresponding length according to the detected size of the lead-acid battery 100.

[0040] Specifically, Figure 8-10 The detection system includes four detection modules 17 respectively arranged on four sides of the lead-acid battery 100; the detection module 17 is fixed on the upper surface of the carrier 16, and the detection module 17 includes a rectangular sleeve 170, a rectangular sleeve rod 171 movably sleeved in the rectangular sleeve 170, and a clamping block 18 is connected to the end of the rectangular sleeve rod 171, a spring A172 is arranged at one end of the rectangular sleeve rod 171 in the rectangular sleeve 170, and a convex ring 173 connected to the spring A172 is arranged on the inner wall of the rectangular sleeve 170; the bottom side of the rectangular sleeve 170 is connected to the movable plate 175 through a spring B174, and a pressure sensor 176 is arranged on one side of the movable plate 175, and the rectangular sleeve rod 171 is provided with a spring A172. A push rod 177 passing through the convex ring 173 is provided at the end of 171. When the spring A172 is in a natural state, the pressure sensor 176 does not detect a pressure signal. At the same time, when the lead-acid battery 100 is placed in the internal area of ​​the four detection modules 17, the bottom end of the lead-acid battery 100 first abuts against the inclined surface of the end of the clamping block 18. At this time, the rectangular sleeve rod 171 can be controlled to shrink into the rectangular sleeve 170, and the push rod 177 abuts against the pressure sensor 176. The degree of contraction of the spring B174 is determined according to the reading of the pressure sensor 176, and the length and width of the lead-acid battery 100 can be determined according to the degree of contraction of the spring B174.

[0041] Based on the above, during use, due to the changes in charging current and actual spray water temperature, the flow rate needs to be adjusted according to actual conditions. Based on this, a drain pipe 10 is connected to the bottom of the shell 1, and a temperature sensor is arranged in the drain pipe 10.

[0042] It should be noted that when the lead-acid battery 100 is taken out of the housing 1 after charging and formation, water droplets will remain on the outer wall of the lead-acid battery 100. In order to facilitate the cleaning of the remaining water droplets, a plurality of jet nozzles 25 are arranged on one side wall of the strip substrate 20 along its length direction, and a water baffle 24 arranged downwardly inclined is arranged on one side of the strip substrate 20 between the jet nozzle 25 and the water spray nozzle 23; and the protruding distance of the sponge block A21 relative to the strip substrate 20 is less than the protruding distance of the sponge block B22 relative to the strip substrate 20; when the telescopic member A11 or the telescopic member B12 extends to the sponge block B22 against the outer wall of the lead-acid battery 100, at this time, the sponge block A21 and the lead-acid battery 1 00 The distance between the outer walls is L; based on the above use, when using the water spray nozzle 23 to spray water, the ends of the sponge block A21 and the sponge block B22 are controlled to touch the outer wall of the lead-acid battery 100, and then the water spray nozzle 23 is started to spray water; at the same time, when it is necessary to control the jet nozzle 25 to blow out air to dry the outer wall of the lead-acid battery 100, the telescopic parts A11 and B12 are controlled to shrink, the sponge block A21 is controlled to separate from the outer wall of the lead-acid battery 100, and at the same time, the ends of the sponge block B22 are kept against the outer wall of the lead-acid battery 100, and the jet nozzle 25 is used to blow out air to dry the outer wall of the lead-acid battery 100.

[0043] It should be noted that, based on the setting of the detection system, the coverage of the air jet nozzle 25 and the water jet nozzle 23 on one side of the strip substrate 20 is adjusted according to the size of the lead-acid battery 100 when in use, and an air supply pipeline and a water supply pipeline are arranged on one side of the strip substrate 20; the plurality of air jet nozzles 25 located at both ends of the strip substrate 20 are connected to the air supply pipeline through an adjustment structure A; the plurality of water jet nozzles 23 located at both ends of the strip substrate 20 are connected to the water supply pipeline through an adjustment structure B; the adjustment structure B and the adjustment structure A have the same structure, such as Fig.11The adjustment structure A includes a tube body 26 connected to the end of the air supply pipeline, a bracket 261 is set at the end of the tube body 26 away from the air supply pipeline, a micro telescopic cylinder 262 is connected to the side of the bracket 261 close to the air supply pipeline, and a piston 27 sliding along the inner wall of the tube body 26 is connected to the end of the micro telescopic cylinder 262. A plurality of exhaust holes 263 are set along the length direction of one side of the tube body 26. The exhaust holes 263 are connected to the jet nozzle 25 through a hose, and then when in use, the piston 27 is driven to slide along the inner wall of the tube body 26 by controlling the extension and contraction of the micro telescopic cylinder 262, and the corresponding exhaust holes 263 are blocked by sliding along the inner wall of the tube body 26, thereby completing the adjustment of the coverage range of the jet nozzle 25 and the water spray nozzle 23.

[0044] The controller is also connected to the pulse charging system to control the water spray nozzle 23 to spray water according to the charging pulse signal. When the pulse charging system controls the water spray nozzle 23 to stop spraying water for 1 second after every 5 seconds of charging, the water spray nozzle 23 is synchronously controlled to stop spraying water for 1 second after every 5 seconds of spraying water.
