The invention relates to a charging pile noise reduction device. The device is characterized in that a vibration filtering box (3) is connected to the outer side of a cooling fan (2), a fan shell (4) and a noise reduction body (5) are arranged in the vibration filtering box (3), a cone noise reduction device (51), a cone fixing block (52) and a noise reduction hole area (53) are arranged in the noise reduction body (5), and each surface of the cone noise reduction device (51) is provided with a noise reflection piece (511) and a noise reduction hole (512); and the end surface of the noise reduction body (5) is connected with a dustproof device (6), and the dustproof device (6) comprises an electrostatic dustproof net (61), an anode device (63) and a cathode device (64). The device has the advantages that an aerodynamic noise transmitted out of the pile body is greatly reduced, meanwhile, the combination of noise reduction and heat dissipation functions in the pile body is considered, external dust is effectively filtered, and a mechanical noise generated by vibration during working of the heat dissipation fan is effectively buffered.

    本发明涉及一种充电桩降噪装置,包括在散热风机(2)的外侧连有滤震箱(3),滤震箱(3)内设有风机壳体(4)和降噪本体(5),降噪本体(5)内包括锥体降噪装置(51)、锥体固定块(52)和降噪孔区(53),锥体降噪装置(51)的每个面上均设有噪声反射片(511)和降噪孔(512);降噪本体(5)的端面连有防尘装置(6),防尘装置(6)包括静电防尘网(61)、阳极装置(63)和阴极装置(64)。本发明的优点是大大降低和减少传出桩体的气动噪声,同时兼顾了桩体内部降噪和散热功能的结合,有效过滤外部灰尘以及缓冲散热风机工作时震动产生的机械噪声。
