[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a centralized charging safety protection device for electric forklifts, including a charging chamber 1 and a heat dissipation mechanism 2. The heat dissipation mechanism 2 is provided inside the charging chamber 1, a support mechanism 3 is provided inside the charging chamber 1, a fixing mechanism 4 is provided on one side of the inner surface of the charging chamber 1, a filter frame 5 is embedded on one side of the inner surface of the charging chamber 1, and a filter layer 6 is provided inside the filter frame 5. The heat dissipation mechanism 2 includes a limiting groove 201 and a protective shell 202. A fan blade 203 is installed inside the limiting groove 201. A motor 204 is fixedly connected to one end of the fan blade 203. A connecting pipe 205 is fixedly connected to one side of the protective shell 202. A flexible hose 206 is connected to one end of the connecting pipe 205, and a suction nozzle 207 is connected to one side of the connecting pipe 205. Through the arrangement of the limiting groove 201, protective shell 202, fan blade 203, motor 204, connecting pipe 205, flexible hose 206, and suction nozzle 207, during use, when the motor 204 is turned on, the motor 204 drives the fan blade 203 to rotate. At this time, the protective shell 202... The internal negative pressure is created by the rotation of the fan blade 203. At this time, the air in the connecting pipe 205 flows into the protective shell 202. The air flowing into the protective shell 202 is discharged from the protective shell 202 through the fan blade 203. Since the air in the connecting pipe 205 flows into the protective shell 202, the suction nozzle 207 delivers the hot air in the charging compartment 1 into the connecting pipe 205. Thus, the suction nozzle 207 can deliver the hot air in the charging compartment 1 into the connecting pipe 205 through air circulation. Then, the hot air in the connecting pipe 205 is discharged from the connecting pipe 205 by the air circulation driven by the fan blade 203, thereby removing the hot air in the charging compartment 1.

[0017] Furthermore, a limiting groove 201 is provided on one side of the surface of the charging compartment 1, and a protective shell 202 is fixedly connected to one side of the inner surface of the charging compartment 1. With the setting of the protective shell 202, when the fan blade 203 is rotating, the protective shell 202 can isolate the fan blade 203 to prevent the charging personnel from touching the fan blade 203 and getting injured.

[0018] Furthermore, one end of the connecting pipe 205 penetrates one side of the surface of the protective shell 202, and both ends of the hose 206 are fixedly connected to the connecting pipe 205. With the hose 206 in use, since the two ends of the hose 206 are connected to the connecting pipe 205, the height of the upper connecting pipe 205 and the suction nozzle 207 can be adjusted, so that the suction nozzle 207 can perform heat absorption operations at different heights.

[0019] Furthermore, the support mechanism 3 includes a first support rod 301, a limiting hole 302, a second support rod 303, a threaded groove 304, a support frame 305, and bolts 306. The first support rod 301 is fixedly connected to one side of the inner surface of the charging compartment 1. A limiting hole 302 is formed on one side of the surface of the first support rod 301. The second support rod 303 is disposed inside the first support rod 301. A threaded groove 304 is formed on one side of the surface of the second support rod 303. A support frame 305 is welded to one end of the second support rod 303. Bolts 306 are threadedly connected to the inside of the threaded groove 304. The charging compartment 1 is connected via the first support rod 301, the limiting hole 302, and the second support rod 303. 3. The setting of threaded groove 304, support frame 305 and bolt 306: In use, support frame 305 can support connecting pipe 205. When the height of connecting pipe 205 and suction nozzle 207 is adjusted, bolt 306 can be turned to disengage from limiting hole 302. Then, the second support rod 303 is slid to a suitable position within the first support rod 301 so that support frame 305 can stably support connecting pipe 205. Then, bolt 306 passes through limiting hole 302 and is threaded to the second support rod 303 through threaded groove 304, thereby fixing the first support rod 301 and the second support rod 303 together.

[0020] Furthermore, the first support rod 301 and the second support rod 303 form a sliding structure. Six sets of limiting holes 302 are provided. Bolts 306 pass through the limiting holes 302 and are threadedly connected to the second support rod 303. Through the setting of the limiting holes 302, in use, the bolts 306 pass through the limiting holes 302 and are threadedly connected to the second support rod 303, which can fix the first support rod 301 and the second support rod 303. The setting of six sets of limiting holes 302 can fix the second support rod 303 at different positions of the first support rod 301.

[0021] Furthermore, the fixing mechanism 4 includes a fixing block 401, a connecting rod 402, a torsion spring 403, a rotating tube 404, a wrench 405, and a fixing strip 406. The fixing block 401 is fixedly connected to one side of the inner surface of the charging compartment 1. The connecting rod 402 is welded to one side of the surface of the fixing block 401. The torsion spring 403 is sleeved on the surface of the connecting rod 402. The rotating tube 404 is sleeved on the surface of the connecting rod 402. The wrench 405 is welded to one side of the surface of the rotating tube 404. The fixing strip 406 is welded to one side of the surface of the rotating tube 404. Through the arrangement of the fixing block 401, connecting rod 402, torsion spring 403, rotating tube 404, wrench 405, and fixing strip 406, during use, the wrench 405 is turned... 5. At this time, the wrench 405 drives the rotating tube 404 to rotate on the surface of the connecting rod 402. Since torsion springs 403 are welded to both ends of the rotating tube 404, the torsion springs 403 rotate at this time. At the same time, the rotating tube 404 drives the fixed strip 406 to move during rotation. Then, the filter frame 5 with the filter layer 6 installed is fitted into the charging compartment 1. Then, the force applied to the wrench 405 is released. Due to the characteristics of the torsion spring 403, the torsion spring 403 returns to its original state, thereby driving the rotating tube 404 to rotate back to its original state on the surface of the connecting rod 402. At this time, the rotating tube 404 drives the fixed strip 406 to return to its original position. The fixed strip 406 will fix the filter frame 5 in the charging compartment 1.

[0022] Furthermore, two sets of torsion springs 403 are provided. One end of the torsion spring 403 is welded to the fixing block 401, and the other end of the torsion spring 403 is welded to the rotating tube 404. The rotating tube 404 and the connecting rod 402 form a mutually rotating structure. With the torsion spring 403, when the torsion spring 403 loses its force after rotation, it will return to its original rotation state. Thus, the rotation of the torsion spring 403 can drive the position of the fixing strip 406 to move. When the force applied to the torsion spring 403 disappears, the rotation of the torsion spring 403 will drive the fixing strip 406 to return to its original position, thereby fixing the filter frame 5 inside the charging compartment 1.

[0023] Working principle: First, adjust the height of the first support rod 301 and the second support rod 303 by adjusting the position of the connecting pipe 205 and the suction nozzle 207, so that the support frame 305 welded to one end of the second support rod 303 supports the connecting pipe 205. Then, fix the filter frame 5 with the filter layer 6 installed inside the charging chamber 1. Then, turn on the motor 204, and the motor 204 drives the fan blade 203 to rotate. At this time, the internal pressure of the protective shell 202 is in a negative pressure state, and the air in the connecting pipe 205 flows into the protective shell 202. The air flowing into the protective shell 202 is discharged from the protective shell 202 through the fan blade 203. Since the air in the connecting pipe 205 flows into the protective shell 202, the suction nozzle 207 delivers the hot air in the charging chamber 1 into the connecting pipe 205. Thus, the suction nozzle 207 can deliver the dust in the charging chamber 1 into the connecting pipe 205 through air circulation. Then, the dust in the connecting pipe 205 is discharged from the connecting pipe 205 by the air circulation driven by the fan blade 203, thereby dissipating the heat in the charging chamber 1.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
