The invention relates to the technical field of dock gate anti-freezing, and particularly discloses a dock gate near-water side anti-freezing method. The method comprises the following steps that S1,a pipeline is arranged at the bottom of a dock gate in contact with seawater, wherein the pipeline is connected with a compressed air blowing device to form an air injection device, and air blowing ports are formed in the bottom of the dock gate by the air injection device; S2, an auxiliary electric heating device is arranged on the outer side of the dock gate, wherein the auxiliary electric heating device is provided with electric heating rods; S3, four sets of the electric heating rods are arranged in the height direction of the dock gate, wherein the positions of the electric heating rods correspond to those of the air blowing ports; and S4, the electric heating rods and the compressed air blowing device on the lower portion are turned on firstly, and after bubbles come out, the electric heating rods on the upper portion are turned on in sequence till the bubbles come out completely. According to the method, on one hand, the air blowing device and the pipeline form the air injectiondevice, continuous bubble groups are generated underwater, formation of ice crystal nucleuses is damaged, and icing is prevented; and on the other hand, the electric heating device is arranged, so that bubbling is facilitated.

    本发明涉及坞门防冻技术领域,具体公开了一种坞门临水侧防冻方法,包括以下几个步骤:S1、在坞门底部与海水接触部分设置管路,管路与压缩空气鼓气装置相互连接,形成喷气装置,喷气装置在坞门底部安装有鼓气口;S2、在坞门外侧设置辅助电加热装置,辅助电加热装置设置有电加热棒;S3、电加热棒沿着坞门高度方向设置有四组,且电加热棒与鼓气口位置相互对应;S4、先打开下方的电加热棒与压缩空气鼓气装置,待有气泡冒出后,打开上方的电加热棒,依次进行,直到起泡完全冒出;本发明所提供的方法,一方面通过空气鼓起装置与管路形成喷气装置,在水下发生连续气泡群,破坏冰晶核形成,防止结冰;另一方面通过设置电加热装置,方便起泡的冒出。
