Embodiment 1

[0037] Embodiment 1: a kind of snow removal method for the snow removal vehicle that is used for clearing the bottom snow accumulation before the EMU overhaul, its main work flow is as follows Figure 8 Shown: When the operator turns on the power, the water in the water tank starts to preheat, the operator presses the start switch of the snow plow truck, the whole vehicle circuit system of the snow plow truck is energized, the chassis transmission and power system (1), the snow melting recovery and reuse system ( 2), the hot water snow removal system (3), the hot water heating and storage system (4), and the hot air blower (5) all start to work, the current receiver (12) receives the current from the track, and passes through the transformer box (13) The electric energy is delivered to the electric motor (16), the hot air blower (5) and the heating wire (17). The electric motor (16) drives the chassis transmission and power system (1), the snow melting recovery and reuse syste...

Embodiment 2

[0038] Embodiment 2: as preferred scheme, on the basis of embodiment 1, as Figure 9 Shown is the work flow of intelligent water valve, can add intelligent water valve switch on the pipeline B (28) that temporary storage tank (27) connects water tank (22), water level sensor is installed inside the water tank, detects the water level of water tank. An embedded microcontroller is installed on the outer shell of the water tank to control the switch of the intelligent water valve according to the detection signal of the water level sensor to prevent the water in the water tank (22) from flowing backwards. When the melted ice and snow fall to the snowmelt recovery and reuse system (2), the water level in the water tank rises. When the water level is lower than the temporary water storage tank, the smart water valve opens, and the water in the temporary water storage tank flows back to the water tank. When the water in the water tank When the water level is higher than the temporar...

Embodiment 3

[0040] Embodiment 3: A snow removal method for snow removal vehicles used to remove snow at the bottom before maintenance of EMUs, its work flow is as follows Figure 11-12 Shown: Figure 11 To control the tempering workflow, Figure 12 Based on the overall control principle of the snow removal vehicle, on the basis of Embodiment 1, the hot water heating system (4) can install a temperature sensor inside the water tank (22) to detect the water temperature, a water level sensor to detect the water level, and install a display screen outside the water tank to display the water temperature , water level, control the power of the heating wire and the output of the display screen through the embedded microcontroller of the water tank, realize the functions of adjusting the water temperature and real-time viewing of the water level and water temperature, and connect to the master microcontroller through the control bus, the master controller and the water pump (43 ), the switch ci...

Abstract

The present invention discloses a snow removal method of a snow remover for clearing accumulated snow at the bottom before the overhaul of CRH trains. The technical solution is that the snow remover receives electric current from the rail through a current collector, electricity is transmitted to an electric motor, a hot air blower and an electric heating wire through a substation, the snow remover concretely comprises a chassis transmission and power system, a hot water snow removal system, a hot water heating and storage system, a snowmelt recycling and reusing system and the like, the hot water snow removal system performs melting snow in a manner of ejecting hot water from a nozzle through the hot water heating and storage system, and the hot air blower in the rear assists in melting snow and has a drying function. The snow remover has the advantages of high flexibility, low manufacturing and use costs and capability of reducing the labor intensity. The current collector receivingelectric current from the electric rail is taken as a power source, so that the snow remover can well adapt to the maintenance environment of CRH trains, and the condition of insufficient energy supply is avoided; and the snowmelt recycling and reusing system is arranged, so that water resources are used to the maximum.

Description

technical field [0001] The invention relates to a snow removal method, in particular to a snow removal method for a snow removal vehicle used for removing snow accumulated at the bottom of a motor train unit before maintenance. Background technique [0002] In severe cold weather, when the high-speed EMUs are running, snow is easy to form on the bottom of the EMUs. If the snow is not removed in time, it will delay the maintenance time, endanger the driving safety, and directly affect the operation capacity of the high-speed rail. At present, my country's treatment methods for this problem are limited and costly. Some are completed by establishing a special fixed ice-melting and snow-removing device, and some are processed by manual snow removal combined with a high-pressure cleaner. Dedicated ice-melting and snow-removing warehouses are costly and inflexible, while artificial snow removal workers are labor-intensive and the quality of snow removal is difficult to guarantee....
