| description | The invention relates to a positive-pressure protection structure for frost prevention of low-temperature equipment, and belongs to the field of low-temperature protection. The positive-pressure protection structure comprises a protection cover and a blowdown pipe, and the blowdown pipe comprises a filler neck, a fixing plate and an annular pipe. The annular pipe is provided with an opening, air spraying holes are formed in the circumferential direction, the fixing plate is further arranged in the circumferential direction of the annular pipe, one end of the fixing plate is connected to the annular pipe, and the other end of the fixing plate is fixedly connected to the low-temperature equipment. One end of the filler neck is connected to the annular pipe and communicates with the space in the annular pipe, and the other end penetrates out of a leading-out hole of the protection cover and then is connected with an air source. The protection cover comprises a disc used for containing the annular pipe and armres |
