Device and method for measuring microwave ice melting efficiency

Abstract

The invention discloses a device and a method for measuring microwave ice melting efficiency. The device comprises a chassis and a test frame; one end of the chassis is hinged with one end of the testframe; a support rod is arranged between the other end of the chassis and the other end of the test frame; the support rod can enable an included angle to be formed between the chassis and the test frame; a test piece for simulating a road surface is arranged on the test frame; an ice layer is arranged on the test piece, a stop block and an alarm triggering device are further arranged on the testframe, the stop block is used for preventing the test piece from sliding on the test frame, the alarm triggering device is used for testing the time required from microwave irradiation on the ice layer to separation of the ice layer and the test piece, and the alarm triggering device is connected to an automatic timer.

Description

technical field [0001] The invention belongs to the technical field of road surface ice melting, and in particular relates to a device and method for measuring microwave ice melting efficiency. Background technique [0002] With the vigorous development of our country's criss-cross road construction, while promoting economic development and facilitating people's travel, it has also brought great pressure to the management and maintenance of roads. Especially in the long winter, the snowfall on the road is easy to form snow accumulation, even ice accumulation, which leads to the reduction of the friction coefficient of the road surface, makes it difficult for vehicles to drive and brake, easily causes traffic accidents, and brings great losses to people's lives and property. At present, the existing purely mechanical deicing equipment in China mainly includes: drum ice breaker, vane deicer, pumping deicer and bionic deicing machine, etc. These devices have the best effect on ...

Problems solved by technology

However, at present, the microwave deicing efficiency index in the indoor test is based on the time required for the surface of the specimen to reach 0°C. This index is quite different from the actual working conditions, and it is impossible to accurately measure the microwave deicing efficiency in the indoor test. Therefore, there is a lack of an accurate measurement. The microwave ice melting efficiency device is used to evaluate the effect of microwave ice melting, which hinders the development and application of microwave ice melting technology
