As background technology, the railway generator car in the prior art has the problem that the temperature of a power room is too low in severe cold weather, and the inventor finds that the problem is caused by the fact that negative pressure of the power room is high, outdoor cold air is sucked from an air inlet of an air conditioner, and the temperature of the power room is almost the same as the outdoor temperature.
For the above reasons, referring to fig. 1, the ventilation method provided by the present invention is applied to a railway generator car including a ventilation duct 10, a first louver assembly 30 and a second louver assembly 50. The first louver assembly 30 is used to clear the ventilation openings of the ventilation duct 10 in the open state and to block a predetermined proportion of the ventilation openings in the closed state. The first louver assembly 30 of fig. 1 is disposed at a lower portion of the vent, but may be disposed at other positions, which is not limited in this embodiment. It can be understood that the opening and closing angle of each blade of the first louver assembly 30 is controlled by the proportional current of the first louver assembly 30, the preset proportion can be determined according to the ratio of the size of the first louver to the size of the vent, for example, when the preset proportion is two thirds, the first louver assembly 30 is set to be the louver assembly with the height same as the height of the vent, the width same as the width of the vent or the width same as the width of the vent, and the height same as the height of the vent, the first louver assembly 30 does not completely shield the vent, so that fresh air can be sucked in, and the danger caused by the non-circulation of air in the power room is avoided. When the blades of the first louver assembly 30 are fully opened, the first louver assembly 30 is in an open state, and the ventilation pipeline 10 is unblocked from the outside air of the railway generator car through the ventilation opening. When the blades of the first louver assemblies 30 are completely closed, the first louver assemblies 30 are in a closed state, and the air flow between the ventilation duct 10 and the external air of the railway generator car through the ventilation openings is blocked by the first louver assemblies 30, so that the speed of air exchange between the external air and the ventilation duct 10 is limited, and the limited degree is related to the preset proportion. The second shutter assembly 50 is used to communicate the ventilation duct 10 with the interior of the railway generator car in the open state to provide an internal circulation passage, and to close the internal circulation passage in the closed state. It can be understood that the opening and closing angle of each of the slats of the second shutter assembly 50 is controlled by the magnitude of the proportional current of the second shutter assembly 50, the slats of the second shutter assembly 50 being in the open state when fully opened, and the slats of the second shutter assembly 50 being in the closed state when fully closed. When the air of the railway power generation car needs to be circulated in the railway power generation car, the air in the railway power generation car can be circulated through the ventilation channel, the air inlet communicated with the interior of the railway power generation car and the inner circulation channel provided by the second shutter assembly 50. As shown in fig. 2, the ventilation method for a railway generator car includes steps S202 to S206.
And S202, acquiring the power room temperature of the railway generator car.
S204, if the temperature of the power room of the railway power generation car is lower than the first temperature, the first shutter assembly is controlled to be in a closed state, and the second shutter assembly is controlled to be in an open state, so that the railway power generation car enters an internal circulation mode.
It can be understood that in the case that the power room temperature of the railway power generation car is lower than the first temperature, the power room temperature of the railway power generation car is lower, and cold air outside should be prevented from entering the interior of the railway power generation car. By controlling the first louver assembly to be in a closed state such that a predetermined proportion of the vents are blocked, the rate of cool air entry is limited. And meanwhile, the second shutter assembly is controlled to be in an opening state, and air with higher temperature in the railway power generation car can form circulation in the railway power generation car through the air inlet of the ventilation pipeline and the second shutter assembly, so that the temperature in the railway power generation car cannot be continuously reduced.
And S206, if the power room temperature of the railway power generation car is higher than the second temperature, controlling the first shutter assembly to be in an opening state and controlling the second shutter assembly to be in a closing state so as to enable the railway power generation car to enter a natural external circulation mode.
The second temperature is higher than the first temperature. It can be understood that in the case that the temperature of the power room of the railway power generation car is higher than the second temperature, the temperature of the power room of the railway power generation car is higher, and the temperature of the interior of the railway power generation car is reduced by sucking the external cold air. The ventilation opening is unblocked by controlling the first louver assembly to be in an opening state, cold air is not blocked by the first louver assembly, negative pressure can be formed due to high temperature inside the railway power generation car, and external cold air is naturally sucked through the ventilation opening, so that the temperature of a power room of the railway power generation car is reduced.
Based on the ventilation method of the railway power generation car in the embodiment, the ventilation mode of the railway power generation car is automatically switched by controlling the first shutter assembly and the second shutter assembly. The railway power generation car is in an internal circulation mode in cold weather, and the power room temperature of the railway power generation car is kept so that the generator set cannot be stopped due to low temperature. When the temperature of the power room of the railway power generation car is higher, the railway power generation car is in a natural external circulation mode, natural air suction is realized through the ventilation opening of the ventilation pipeline, and the temperature of the power room of the railway power generation car is reduced. The ventilation method of the railway generator car realizes that the generator set can work at the optimal temperature, reduces the failure rate, ensures the power supply capacity of the railway generator car, and is energy-saving and environment-friendly.
In one embodiment, a heating device is also arranged in the railway generator car. As shown in fig. 3, the ventilation method for a railway generator car further comprises step S302 and step S304.
S302, if the temperature of the power room of the railway power generation vehicle is lower than the first temperature, the first shutter assembly is controlled to be in a closed state, and the second shutter assembly is controlled to be in an open state, so that the railway power generation vehicle enters an internal circulation mode.
Step S302 is the same as step S204, and the above can be referred to.
And S304, if the power room temperature of the railway power generation car is lower than the third temperature after the railway power generation car is in the internal circulation mode, controlling a heating device of the railway power generation car to heat.
The third temperature is less than the first temperature. It can be understood that if the temperature of the power room of the railway power generation car is continuously reduced to the third temperature after the railway power generation car is in the internal circulation mode for a period of time, the temperature of the power room of the railway power generation car cannot be maintained only by the internal circulation of air, and the power room of the railway power generation car is heated by the heating device.
In one embodiment, a fan is arranged in the railway generator car, and the fan is used for providing power for air flow of outside air and air in the railway generator car through the ventilation opening when in work. As shown in fig. 4, the ventilation method for the railway generator car includes steps S402 and S404.
S402, if the power room temperature of the railway power generation car is higher than the second temperature, controlling the first shutter assembly to be in an opening state and controlling the second shutter assembly to be in a closing state so as to enable the railway power generation car to enter a natural external circulation mode.
Step S402 is the same as step S206, and the above description can be referred to.
S404, if the temperature of the power room of the railway power generation car is higher than the fourth temperature after the railway power generation car is in the natural external circulation mode, controlling a fan of the railway power generation car to work so as to enable the railway power generation car to enter a forced external circulation mode. The fourth temperature is higher than the second temperature.
It can be understood that if the temperature of the power room of the railway power generation car continuously rises to the fourth temperature after the railway power generation car is in the natural external circulation mode for a period of time, the fact that cold air naturally sucked by negative pressure of the railway power generation car is insufficient to reduce the temperature of the power room of the railway power generation car means that air is sucked by the negative pressure of the railway power generation car only, and therefore the temperature of the power room of the railway power generation car is reduced by increasing the amount of cold air flowing through the ventilation opening through the air suction of the fan.
In one embodiment, the railway generator car is further provided with a refrigeration device. As shown in fig. 5, the ventilation method for a railway generator car includes steps S502 to S506.
And S502, if the power room temperature of the railway power generation car is higher than the second temperature, controlling the first shutter assembly to be in an open state and controlling the second shutter assembly to be in a closed state so as to enable the railway power generation car to enter a natural external circulation mode.
Step S502 is the same as step S206, and the above can be referred to.
And S504, if the temperature of the power room of the railway power generation car is higher than the fourth temperature after the railway power generation car is in the natural circulation mode, controlling a fan of the railway power generation car to work so as to enable the railway power generation car to enter a forced external circulation mode. The fourth temperature is higher than the third temperature.
Step S504 is the same as step S404, and the above can be referred to.
And S506, if the temperature of the power room of the railway power generation car is higher than the fifth temperature after the railway power generation car is in the forced external circulation mode, controlling a refrigerating device of the railway power generation car to refrigerate so as to enable the railway power generation car to enter a cooling mode.
The fifth temperature is higher than the fourth temperature. It can be understood that if the temperature of the power room of the railway power generation car continuously rises to the fifth temperature after the railway power generation car is in the forced external circulation mode for a period of time, the temperature of the power room of the railway power generation car is not sufficiently reduced by cold air sucked by the fan, and therefore the temperature of the power room of the railway power generation car is reduced by starting the refrigeration device for refrigeration.
In one embodiment, the first temperature is 15 deg.C, the second temperature is 25 deg.C, the third temperature is 10 deg.C, the fourth temperature is 28 deg.C, and the fifth temperature is 30 deg.C.
In one embodiment, the ventilation method of the railway generator car further comprises the following steps: and responding to the command of passing through the sand storm area, and controlling the railway power generation car to enter an internal circulation mode if the railway power generation car is not in the internal circulation mode. The ventilating mode of the railway power generation vehicle is forced to be the internal circulation mode when the railway power generation vehicle passes through the sand wind road section, so that the condition that the sand wind enters the railway power generation vehicle to damage equipment in the railway power generation vehicle is relieved. The command of the sandstorm section can be directly sent to the railway power generation car by the railway dispatching center, and can also be sent to the train power generation car by train operators according to the judgment of a map and the surrounding environment.
In one embodiment, the ventilation method of the railway generator car further comprises the following steps: and controlling the railway generator car to recover the ventilation mode before responding to the command of passing through the sand storm area in response to the command of passing through the sand storm area. It can be understood that the original ventilation mode of the railway generator car is restored adaptively after the railway generator car is driven out of a sand storm area.
In one embodiment, the blower of the railway generator car is used for providing power for air flow of outside air and air inside the railway generator car through the ventilation opening when in operation, and the ventilation method of the railway generator car further comprises the following steps: and if the cooling water temperature of the diesel engine of the railway power generation car is higher than the sixth temperature, controlling the first shutter assembly to be in an open state, controlling the second shutter assembly to be in a closed state, controlling the fan of the railway power generation car to work, and controlling the refrigerating device of the railway power generation car to refrigerate so as to enable the railway power generation car to enter a cooling mode until the cooling water temperature of the diesel engine of the railway power generation car is reduced to the normal working temperature, and enabling the railway power generation car to recover to enter the ventilation mode before the cooling mode. It can be understood that the generator set of the railway generator car generally comprises a main diesel engine and an auxiliary diesel engine, and the diesel engine referred to in the embodiment can be the main diesel engine or the auxiliary diesel engine. When the temperature of the cooling water of the diesel engine is too high, the water cooling device of the diesel engine cannot effectively cool the diesel engine, and the temperature of the power room of the railway generator car is reduced to assist the diesel engine in cooling. When the temperature of the cooling water of the diesel engine is reduced to the normal working temperature, the cooling water of the diesel engine can effectively cool the diesel engine, so that the ventilation mode before cooling the diesel engine for auxiliary cooling is adaptively recovered. In one embodiment, the sixth temperature is 95 ℃ when the diesel engine is a primary diesel engine and 92 ℃ when the diesel engine is a secondary diesel engine.
In one embodiment, referring to fig. 1, a first louver assembly 30 is disposed below the vent opening, and a blower of the railway power car is operable to provide motive force for air movement of outside air through the vent opening and air within the railway power car. The ventilation method of the railway power generation car further comprises the following steps: if the time length of the railway power generation vehicle in the internal circulation mode exceeds a first preset time length, the first shutter assembly is controlled to be in an open state, the second shutter assembly is controlled to be in a closed state, and a fan of the railway power generation vehicle is controlled to work, so that the railway power generation vehicle enters a forced external circulation mode. It can be understood that, because the density of the hot air is lower than that of the cold air, the hot air can float upwards to be gathered at the top of the power room of the railway power generation car after the railway power generation car is in the internal circulation mode for a long time, the embodiment can automatically discharge high-temperature and under-circulated gas gathered at the top of the power room regularly, and because the first louver assemblies are arranged at the lower parts of the ventilation openings, the gathered gas can be smoothly discharged from the upper parts of the ventilation openings which are not shielded by the first louver assemblies.
It should be understood that, although the steps in the flowcharts of fig. 2 to 5 are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
