When the eyes or bodies of chemical workers accidentally come into contact with toxic and harmful chemicals, the emergency cleaning device can quickly clean the toxic and harmful substances attached to the human body, and achieve emergency treatment by using a large amount of water to quickly spray and rinse, thereby reducing the degree of injury and avoiding further damage to the human body caused by chemicals; Most of the emergency spray eyewash equipment in the prior art adopts a single-pipeline above ground water supply, and the pressure in the pipeline is maintained at 0.3-0.5MPa by a water supply pump. When it is needed, the valve is opened for use. In the cold northern regions, an electric heating tape is generally installed on the water supply pipeline, and an insulation layer is added to prevent the pipeline from being frozen and blocked. However, the spray nozzle cannot be dust-proofed, resulting in blockage of the spray nozzle and affecting the spray effect.

It should be noted that the larger the value of the heating assessment coefficient, the smaller the risk of abnormal heating effect of the electric heating belt (19); obtaining the heating time within the heating time The line risk value of the electric heating tape (19), the line risk value represents the part of the reactive power per unit time of the power supply line of the electric heating tape (19) that is greater than the preset reactive power per unit time threshold, and the product value obtained by normalizing the difference between the initial temperature value of the line and the maximum temperature value of the line, and comparing and analyzing the preset heating assessment coefficient threshold and the preset line risk value threshold entered and stored internally: if the heating assessment coefficient is less than the preset heating assessment coefficient threshold, and the line risk value is less than the preset line risk value threshold, a normal signal is generated and sent to the damage interference unit; if the heating assessment coefficient is greater than or equal to the preset heating assessment coefficient threshold, or the line risk value is greater than or equal to the preset line risk value threshold, a risk signal is generated.

7. The antifreeze emergency eyewash device according to claim 6, characterized in that: The spray control monitoring feedback operation process of the damage interference unit is as follows: the water pressure risk value of the shower head (7) and the eyewash nozzle (17) within the time threshold is obtained, the water pressure risk value represents the product value obtained after data normalization processing of the water pressure evaluation value inside the water inlet pipe (3) and the part of the water flow rate average lower than the preset threshold, the water pressure evaluation value represents the difference between the maximum peak value and the minimum trough value in the water pressure characteristic curve inside the water inlet pipe (3) within the time threshold, the water pressure risk value is compared and analyzed with the preset water pressure risk value threshold, and the part of the water pressure risk value greater than the preset water pressure risk value threshold is marked as the control demand value. It should be noted that the larger the value of the control demand value, the higher the water flow control demand inside the water inlet pipe (3), and the control demand value is compared and analyzed with the preset control demand value threshold recorded and stored inside: if the control demand value is less than the preset control demand value threshold, no signal is generated; If the control demand value is greater than or equal to the preset control demand value threshold, a control signal is generated.
