Outdoor closed type high-speed train ice melting and snow removing system

Abstract

The invention discloses an outdoor closed type high-speed train ice melting and snow removing system which comprises a concave groove maintaining structure, a linear segment closing device, an arc line closing device, a hot air heating device and a water collection and drainage groove. The concave groove maintaining structure, the linear segment closing device, the arc line closing device and the bottom of a high-speed train form a closed outdoor space jointly. The outdoor closed type high-speed train ice melting and snow removing system has the advantages that only the closed space at the bottom of the train is heated, the temperature of air inside the closed space is rapidly increased and kept from 45 DEG C to 60 DEG C, and the ice melting time can be shortened. Compared with a whole compartment interior large-space whole warming, ice melting and snow removing way, needed heating energy consumption is greatly reduced, the effective utilization rate of heat energy is improved, and the operation cost is reduced; adverse influences of high-temperature environment needed by ice melting on other operations of a large compartment can be avoided.

Description

technical field [0001] The invention relates to an ice-melting and snow-removing system for a high-speed rail train, in particular to an outdoor closed-type ice-melting and snow-removing system for a high-speed rail train. Background technique [0002] High-speed rail trains run in cold regions, and the bottom of the car body is frozen with ice and snow. After running for 4,000 kilometers or 48 hours, it is necessary to return to the garage for a first-level inspection. Each first-level inspection should be completed within about 3 and a half hours. Melt ice to meet the ice-melting and snow-removing standard, and there must be no residual ice and snow in all parts of the travel department, so as to ensure the normal operation of subsequent operations and complete a first-level maintenance on time and with high quality. Therefore, there is a great need for a fast melting ice system to solve the problem of rapid melting of ice and snow at the bottom of the car body when the hi...

AI Technical Summary

Problems solved by technology

The ambient air temperature in the garage space only needs to be 14-16°C, and a higher temperature is not required. Passively increasing the air temperature in the garage ambient space consumes a lot of energy, resulting in a lot of waste, and at the same time increases the installed capacity of the hot air system. Large, initial investment and operating costs increase

[0007] 2. The 60°C hot air sent by the current hot air ice melting system through the tuyere is a point heat source, which can only directly contact the local area at the bottom of the train. Most of the area at the bottom of the train melts ice under the influence of the ambient temperature of the garage at 30-35°C, which is beneficial to speed up Unfavorable melting time

[0008] 3. The high room temperature during the deicing period of the garage also greatly affects other operations. During the deicing period, the trains on other tracks cannot be operated at the same time, and the overall utilization rate of the garage is reduced.

[0009] 4. The ice melting operation is only needed in winter, and the air outlet of the current hot air ice melting system is higher than the ground, which will affect the convenience of the process operation to a certain extent

[0010] 5. With the rapid development of domestic high-speed rail, the number of high-speed rail trains on the line is getting larger and larger, and the amount of inspection and maintenance operations has increased sharply. Setting ice melting and snow removal functions in the inspection and maintenance depot will greatly affect the efficiency of inspection and maintenance operations
