Description

Technical Field

[0001] The utility model relates to the technical field of compressors, and particularly relates to a high-temperature warning device for a railway locomotive compressor. Background Technique

[0002] The existing oil temperature detection device of the railway electric locomotive compressor is located at the exhaust port, in the middle of the main engine body, and the temperature is set at 110±5°C. It is in a normally closed state and is connected in series to the control circuit. When the exhaust temperature exceeds the set value, the temperature switch disconnects, and the air compressor shuts down power, playing a role in over-temperature protection. However, the crew members cannot take timely measures to stop at the station ahead or conduct out-of-depot maintenance, resulting in in-zone stops, rescues, and blockages of the main line due to the over-temperature protection of the compressor.

[0003] The high-temperature warning device for locomotive compressors solves the problem that crew members cannot monitor the compressor temperature in real time during the operation of electric locomotives. However, such previous devices often only measure according to the pre-set temperature, lacking the assistance of devices such as displays and alarms, and it is difficult for crew members to take corresponding measures based on the real-time temperature.

[0004] This temperature sensor is installed at the reserved joint of the oil drain plug of the compressor, and by monitoring the oil temperature in real time, it ensures that the locomotive compressor operates within an appropriate temperature range, and measures the oil temperature by sensing the heat conduction ability of the oil.

[0005] Now, a new high-temperature warning device for a railway locomotive compressor is proposed to solve the above problems. Content of the Utility Model

[0029] Embodiment 2: Positioning blocks 4 are respectively provided at the upper and lower parts on the right side of the compressor frame body 1, and screws 5 are engaged in screw holes on the left side of the front ends of the positioning blocks 4. A slot 25 is provided inside the left side of the positioning blocks 4, and a slideway 12 is provided between the front and rear of the right side inside the positioning blocks 4. Protruding blocks 23 are respectively fixed at the front and rear ends of the top and bottom of the single-chip microcomputer controller 6, and steel balls 13 are movably inlaid in the protruding blocks 23;

[0030] The protruding blocks 23 are embedded in the slideway 12, and the steel balls 13 can roll along the inner wall of the slideway 12. The positioning blocks 4 are clamped on the surface of the compressor frame body 1 by means of the slots 25.

The single-chip microcomputer controller 6 can move together with the protruding blocks 23, and the protruding blocks 23 and the slideway 12 are in the same vertical plane;

[0031] Specifically, as shown in Figure 1 , Figure 2 , Figure 4 and Figure 5 , the positioning block 4 is clamped and fixed on the surface of the compressor frame body 1 through the slot 25 on the left side, and the screw 5 in the screw hole is turned to implement reinforcement.

The thermistor 20 on the temperature sensor 16 has a resistance value that changes with temperature. When the temperature of the compressor oil changes, the resistance value of the thermistor 20 also changes accordingly. The circuit will measure this change and convert it into an electrical signal. The electrical signal is converted into a digital signal by the single-chip microcomputer controller 6 and displayed as the temperature of the compressor oil by the LED display 9, and a warning sound is emitted in cooperation with the voice generator 7.
