Device for preventing water from freezing through surface ultrasonic vibration disturbance and using method

Abstract

The invention discloses a device for preventing water from freezing through surface ultrasonic vibration disturbance, and relates to the field of water conservancy and water affairs. The device comprises an adjustable grid frame, a plurality of ultrasonic vibration generators are arranged on the adjustable grid frame at intervals, and each ultrasonic vibration generator comprises a semi-submersible vibration electrode; riding tracks are arranged on the two sides of a main water conveying canal, and mobile power supply control boxes are arranged on the riding tracks and connected with the ultrasonic vibration generators. The device can effectively prevent a water delivery trunk canal similar to a midline project and a higher latitude water delivery project from being frozen in winter, so that a complex, passive and low-efficiency ice cover water delivery mode can be replaced, normal freezing-free water delivery of the trunk canal in an ice period is achieved, the trunk canal water delivery efficiency can be greatly improved, the trunk canal ice period water delivery safety is guaranteed, and remarkable social benefits and economic benefits are achieved. The invention further relates to a construction method of the device for preventing the water from freezing through surface ultrasonic vibration disturbance.

Description

technical field [0001] The invention relates to the field of water conservancy and water affairs, more specifically, it is a surface layer ultrasonic vibration disturbance waterproof body freezing device. The invention also relates to a method for using the surface layer ultrasonic vibration disturbance waterproof body freezing device. Background technique [0002] Main water conveyance canals, especially artificial water conveyance main canals, such as the main canal of a central line project, use artesian water delivery from south to north, and have the characteristics of wide artificial channels (80m-120m) and long distances (over 1200km); Due to the long distance and the latitude spanning from 33° to 40°, freezing occurs almost every year in the north of the main canal of the Yellow River. [0003] At present, the water delivery method of a central main canal during the glacial period is under the ice cover, and the safety measure is to use the ice-blocking cable; under...

AI Technical Summary

Problems solved by technology

[0003] At present, the water delivery method of a central main canal during the glacial period is under the ice cover, and the safety measure is to use the ice-blocking cable; under this method, the water delivery efficiency during the glacial period is about half of the normal time, and the actual operation is due to the flow rate and other reasons. The formation of ice sheets is difficult, and disasters such as ice plugs and ice dams are easy to form, and the actual water delivery is seriously low; in addition, the freezing of main canals will bring serious safety hazards to control facilities such as gates, and even cause permanent damage
