Description

Technical Field

[0001] This utility model belongs to the field of locomotive pipeline testing technology, and in particular relates to the housing structure for monitoring temperature and humidity in locomotive and rolling stock air ducts. Background Technology

[0002] Locomotive piping refers to the pipeline system on a locomotive used to transport various fluid media. It is a key component of the locomotive's power, braking, and cooling systems. Among them, the air duct is an important part of the locomotive piping system, used to transport compressed air. When the temperature and humidity inside and outside the air duct change too much, the air inside the air duct may condense, which can seriously affect the locomotive's braking system and other air-using equipment. This safety risk is particularly prominent in cold northern regions. Although modern air supply systems are equipped with air purification devices, excessively high temperature and humidity inside the air duct can still occur. Therefore, it is necessary to monitor, record, and provide early warning of the internal temperature and humidity of the air duct.

[0003] To facilitate temperature and humidity monitoring within air ducts, temperature and humidity monitoring devices are typically used. These devices mainly consist of three parts: a connector, a housing, and a sensor. The connector is welded to the air duct to connect the housing. The housing houses the sensor, which monitors the temperature and humidity of the air inside the housing. However, during use, some moisture in the air condenses into water droplets on the sensor probe. The presence of these droplets affects the accuracy of the sensor's air monitoring, resulting in poor accuracy. Furthermore, the cross-sectional area of ​​the air outlet on the housing is fixed, making it difficult to adjust the exhaust speed of the housing based on the airflow velocity within the air duct.

[0004] To address these issues, we have provided a housing structure for monitoring temperature and humidity in the air ducts of locomotives and rolling stock. Utility Model Content

[0005] The purpose of this invention is to provide a housing structure for monitoring temperature and humidity in the air duct of locomotives and rolling stock. A push plate and push rod drive a moving frame, which in turn brings a sponge block into contact with the probe of the temperature and humidity sensor. The sponge block wipes the probe, solving the problem of inconvenient cleaning of the sensor probe in existing systems. Simultaneously, a threaded rod and slider drive a moving block, causing the ventilation holes and air outlets on the moving block to be misaligned, thus controlling the airflow speed from the measuring chamber and resolving the problem of inconvenient control of the airflow speed in existing systems.

Ventilation holes are opened on the surface of the movable block.

[0010] A further feature of this invention is that one end of the air intake pipe is threaded into the inside of the connector, and the other end of the air intake pipe passes through the top of the measuring chamber and is fixedly connected to the shut-off valve. The shut-off valve is located inside the measuring chamber, and the valve stem of the shut-off valve extends to the outside of the measuring chamber.

[0013] A further feature of this invention is that air vents are respectively located at the front and rear ends of the top of the measuring chamber, and a warning light is provided on the lower side of one outer wall of the measuring chamber.

[0014] A further feature of this invention is that connecting rods are fixedly connected to the upper and lower sides of the front and rear ends of the movable frame, and the end of the connecting rod away from the movable frame passes through the sliding groove on the mounting bracket and is threadedly connected to a second plate.

[0015] A further feature of this invention is that a first return spring is provided on the outer side of the push rod, and the two ends of the first return spring are respectively fixedly connected to the lower side of the outer wall of the measuring chamber and the outer wall of the push plate near the measuring chamber.

[0016] A further feature of this invention is that a second return spring is fixedly connected to the inner walls of both sides of the fixed frame, and the end of the second return spring away from the inner wall of the fixed frame is fixedly connected to the outer walls of both sides of the movable block.
