Description

Technical Field

[0001] The utility model belongs to the technical field of sensors, and specifically relates to an integrated temperature vibration sensor. Background Art

[0002] Temperature and vibration sensors can not only monitor the vibration speed of mechanical equipment and factors related to mechanical vibration, but also measure the temperature of mechanical equipment in real time. They are widely used in electromechanical equipment such as motors, fans, bearings, reducers, generators, gas engines, centrifuges, etc. to monitor the operating temperature and vibration status of electromechanical equipment in real time. Figure 1 As shown, it mainly includes a base at the bottom, a sensor body in the middle and a sensor antenna at the top. During installation, the base is fixed to the surface of the electromechanical equipment by AB glue, and the sensor body is threadedly connected to the base. When the above connection structure is connected, if the bolts are not tightened in place, it is easy to cause loosening during subsequent use. If the bolts are overloaded, it is easy to slip and affect the tightening effect. At the same time, during use, under the long-term vibration of the electromechanical equipment, the threaded connection between the sensor body and the base is easy to loosen. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to have a clearer understanding and knowledge of the present invention, the present invention is further described in detail in conjunction with the following embodiments. It should be noted that the specific embodiments described below are only used to explain the present invention and facilitate understanding. The technical solutions provided by the present invention are not limited to the technical solutions provided by the following embodiments, and the technical solutions provided by the embodiments should not limit the protection scope of the present invention.

[0024] Example

[0025] like Figures 2 to 6 As shown, this embodiment provides an integrated temperature vibration sensor, including a temperature vibration sensor body, an antenna arranged at the upper end of the temperature vibration sensor body and a probe at the lower end. The above structure can adopt an existing mature structure, so it will not be described here.

[0026] The present embodiment provides a mounting base threadedly connected to the temperature vibration sensor body. Specifically, the mounting base is cylindrical, and a first through hole is opened in the middle along the axis, the first through hole penetrates the mounting base, and a connecting column with an external thread is arranged at the upper end of the mounting base, the connecting column and the mounting base are coaxially arranged and a second through hole coaxial with the first through hole is arranged in the middle. Adapted to the mounting base, the present embodiment also provides a connecting sleeve with an internal thread matching the connecting column at the lower end of the temperature vibration sensor body, and the radius of the connecting sleeve is equal to that of the mounting base.

[0027] The connecting sleeve and the bottom of the temperature vibration sensor body are an integrated structure. Based on the structural setting of the connecting sleeve, in this embodiment, the probe is located at the middle axis position in the connecting sleeve and extends to the outside of the connecting sleeve. When installing and connecting, the connecting sleeve is threadedly connected to the connecting column on the mounting base, and the end face of the mounting base is abutted against the end face of the connecting sleeve.

[0028] On the basis of the above structure, in this embodiment, a plurality of mounting grooves are arranged on the mounting base at intervals around its circumference, positioning steel balls are installed in the mounting grooves through springs, and a plurality of positioning through holes corresponding to the mounting grooves are arranged on the connecting sleeve at intervals around its circumference, the positioning steel balls can move along the mounting grooves and their upper parts can be snapped into the positioning through holes; preferably, there are three mounting grooves and they are evenly distributed along the circumference of the mounting base, and there are three corresponding positioning through holes and spring positioning steel balls, which correspond to each other one by one; under normal conditions, the positioning steel balls are supported by the springs. The upper part of the connecting sleeve protrudes from the upper end surface of the mounting base. When installing and connecting, the connecting sleeve is aligned with the connecting column on the mounting base and tightened in the direction of the mounting base. The bottom end of the connecting sleeve contacts the positioning steel ball. The connecting sleeve continues to rotate, and the end surface of the connecting sleeve presses the positioning steel ball in the direction of the mounting base and compresses the spring. When the connecting sleeve continues to rotate until the mounting groove is docked with the positioning through hole, the positioning steel ball bounces up under the action of the spring restoring force and its upper part is stuck in the positioning through hole. At this time, the connecting sleeve and the mounting base are connected and tightened in place, thereby achieving installation. Through the above arrangement, on the one hand, the operator can judge whether the connecting sleeve and the mounting base are tightened in place by the impact sound of the positioning steel ball when it bounces up with the connecting sleeve or by observing whether there is a positioning steel ball in the positioning through hole. On the other hand, after the positioning steel ball is stuck in the positioning through hole, the relative displacement of the connecting sleeve and the mounting base can be limited, which has a good anti-loosening effect.

[0029] After the installation is completed, the probe extends into the first through hole and the second through hole and contacts the installation surface of the electromechanical equipment. This setting can better ensure the temperature measurement effect of the temperature vibration sensor. In a further preferred embodiment, a silicone thermal conductive sheet is also provided at the end of the probe, thereby further improving the temperature measurement effect of the temperature vibration sensor.

[0030] The mounting base is fixed to the surface of the electromechanical equipment by bonding with AB glue. Taking into account the setting of the first through hole, in order to avoid excessive AB glue on the bottom of the mounting base causing the AB glue to overflow into the first through hole and affect the probe, this embodiment provides an annular glue overflow groove and a plurality of strip glue overflow grooves arranged in a ring-shaped interval at the bottom of the mounting base, one end of the strip glue overflow groove is connected to the annular glue overflow groove, and the other end extends to the edge of the mounting base.

[0031] In a further preferred embodiment, an external thread is provided at the upper end of the temperature vibration sensor body, and an antenna cap is provided at this end and is threadedly connected to the upper end of the temperature vibration sensor body. The antenna cap is made of plastic material and covers the antenna, thereby providing better protection for the antenna.

[0032] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
