Description

Bearing bush temperature sensor

Technical Field

The utility model relates to the technical field of sensors, in particular to a bearing bush temperature sensor.

Background

The temperature sensor, as its name implies, is a temperature measuring device which can convert the temperature signal into an electrical signal convenient for utilization, and has the characteristics of high sensitivity, good stability, good interchangeability, high precision and the like, and is usually used in combination with a display instrument, a recording instrument, an electronic regulator and the like.

At the axle bush department of marine engine, need use temperature sensor to detect the axle bush temperature, the sensor that the tradition adopted is direct with sensor rigid contact in axle bush department, after a period, with the probe of axle bush contact by the wearing and tearing back, lead to the data precision of gathering inaccurate, the axle bush goes wrong, does not take place to report to the police. On the other hand, the adopted rigid assembly sensor support is easy to break and fall into an engine cavity to influence the work of the engine, and the maintenance cost of the engine is very high, so that a new bearing bush temperature sensor is needed for overcoming the existing defects.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides a bearing bush temperature sensor, and the specific technical scheme is as follows:

axle bush temperature sensor, its characterized in that: comprises a sleeve, an extension tube, a probe, a spring and a temperature sensor;

the telescopic pipe is arranged in the sleeve in a penetrating mode, a first limiting piece is arranged in the middle of the telescopic pipe, the spring is sleeved on the telescopic pipe, blocking pieces are arranged at the bottom in the sleeve, the spring is located between the limiting pieces and between the blocking pieces, a data transmission port of the sensor is connected with a sensing line, the sensor is placed in the telescopic pipe, and the temperature sensor is used for collecting the temperature of the probe.

To better implement the utility model, the following steps can be further carried out: the probe comprises a fixed shell and a contact assembly, the contact assembly is installed at the upper end of the fixed shell, and the lower end of the fixed shell is inserted into the upper end of the telescopic pipe.

Further: and threads are arranged on the periphery of the lower end of the extension tube.

Further: the sensing wire penetrating out of the telescopic pipe is sleeved with a protective sleeve, and the inner end of the protective sleeve is in threaded fit with the threaded end of the telescopic pipe.

The utility model has the beneficial effects that: overall structure is simple, and the spring drives the telescopic link and stretches out from the cover intraductal for the contact that the probe can be firm is avoided the probe wearing and tearing to take place the wrong report on the axle bush, perhaps the probe damages, and the axle bush goes wrong and does not take place to report to the police, simultaneously, embeds the telescopic link at the intraductal, protects the installation to the telescopic link through the sleeve pipe, avoids traditional rigid connection to lead to the piece to fall into and lead to subsequent huge maintenance cost in the engine cavity.
