Description

Technical Field

[0001] The utility model relates to the technical field of temperature vibration sensors, in particular to a wireless temperature vibration integrated sensor. Background Art

[0002] In the modern industrial field, equipment status monitoring and maintenance are key links to ensure the normal operation of production. With the continuous advancement of technology, sensors play an increasingly important role in equipment monitoring. Among them, vibration sensors, as a powerful tool for intelligent operation and maintenance of equipment, have unique advantages and potential.

[0003] The application scenarios of vibration sensors are relatively complex. In many places, wired vibration sensors cannot be used due to installation environment issues. Although there are vibration sensors that use wireless signal transmission, the antennas of these sensors are interfered by the metal casing, so the antennas can only be placed outside the casing, which can easily cause damage to the antennas. At the same time, vibration sensors and temperature sensors need to be installed separately, which increases the installation process and the space occupied by the equipment, and cannot meet the needs of some occasions with small installation space. For this reason, we propose a wireless temperature-vibration integrated sensor to solve the above problems. Utility Model Content

[0014] 2. Placing the spring antenna inside the plastic shell effectively prevents the antenna from being damaged by the external environment. At the same time, the plastic shell is a plastic part.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-3 A wireless temperature-vibration integrated sensor comprises a shell base 1. A threaded hole 12 is provided at the bottom of the shell base 1 for easy installation. A piezoelectric vibrator 2 is installed at the bottom of the shell base 1. The piezoelectric vibrator 2 is mounted at the bottom of the shell base 1 by epoxy resin potting glue to ensure that the piezoelectric vibrator 2 will not be oxidized.

[0023] A temperature probe 3 is provided at the bottom of the shell base 1, a metal cover 6 is fixed to the upper end of the shell base 1, a control unit 5 is fixed to the lower end of the metal cover 6, the temperature probe 3, the piezoelectric vibrator 2 and the control unit 5 are connected to each other, a spring antenna 10 is connected to one side of the control unit 5, and a battery fixing cover 9 is detachably mounted on the metal cover 6. The battery fixing cover 9 can effectively prevent the influence of the vibration of the battery 8 on the data during the measurement process of the sensor, thereby enhancing the accuracy of the sensor data.

[0024] A battery 8 is installed in the battery fixing cover 9, and the spring antenna 10 penetrates the metal cover 6 and the lower side wall of the battery fixing cover 9 and extends to the upper end of the metal cover 6. Placing the spring antenna 10 inside the sensor housing effectively prevents the antenna from being damaged by the external environment.

[0025] The battery 8 is connected to the control unit 5, and the upper end of the housing base 1 is threadedly connected with a plastic housing 11, which is a plastic part. Compared with other full metal housings, the plastic housing will not interfere with the signal and will not affect the transmission of the signal.

[0026] An external thread is provided around the upper end of the shell base 1, and a metal thread insert 4 is embedded around the bottom of the plastic shell 11, and the metal thread insert 4 and the external thread are screwed together, thereby avoiding wear of the plastic part thread when the plastic part is connected to the metal part, resulting in a loose connection between the plastic shell 11 and the shell base 1.

[0027] The battery fixing cover 9 is detachably connected to the upper end of the metal cover 6 by fixing screws 7. The battery 8 and the spring antenna 10 are connected to the control unit 5 through the opening on the metal cover 6. The battery fixing cover 9 ensures that the battery 8 is fixed to the shell base 1, effectively preventing the vibration of the battery 8 during the measurement process of the sensor from affecting the data, and at the same time provides space and protection for the battery installation.

[0028] The control unit 5 is composed of a control mainboard and a communication mainboard. The control mainboard and the communication mainboard are integrated with a low-power system, which greatly increases the use time of the sensor and can effectively avoid the problem of frequent battery replacement. The battery 8 uses a large-capacity lithium battery, which also greatly increases the use time of the sensor.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
