[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0027] See also Figure 1-5 A wireless vibration monitoring device includes a vibration sensor 6, a magnetic head 8 is fixedly connected to the bottom end of the vibration sensor 6, a protective shell 2 is installed outside the vibration sensor 6, a cavity is opened at the upper end of the protective shell 2, a first elastic member 9 is fixedly connected to the cavity, one end of the first elastic member 9 is fixedly connected to a buffer head 10, and the other end of the buffer head 10 abuts the vibration sensor 6, a cavity is symmetrically opened in the middle of the protective shell 2, a second elastic member 11 is fixedly connected to the cavity, one end of the second elastic member 11 is fixedly connected to an abutting block 12, and the other end of the abutting block 12 abuts the vibration sensor 6. When the device is hit, the buffer head 10 is pushed inward by the first elastic member 9. The vibration sensor 6 is squeezed inwardly by the buffer head 10, so that the vibration sensor 6 is always tightly adsorbed on the detected device. At the same time, the two second elastic members 11 use their own elasticity to squeeze the abutment blocks 12 inwardly at the same time. The two abutment blocks 12 squeeze the middle part of the vibration sensor 6 inwardly at the same time, so that the vibration sensor 6 is adsorbed within the detection range of the detected device, thereby improving the detection accuracy of the device. Grooves are symmetrically opened on the outer side of the protective shell 2, and multiple heat sinks 4 are fixedly connected in the two grooves. The internal accumulated heat is conducted out of the protective shell 2 through the heat sink 4 to avoid excessive temperature accumulation of the protective shell 2 and affect the operation of the vibration sensor 6.

[0028] It is worth mentioning that the vibration sensor 6 consists of a shell, a battery management unit, a circuit board, fasteners, a support plate, a sensor circuit board, a magnetic base assembly, and an antenna; the magnetic base assembly is fixed to the outer bottom end of the shell, and is fixed by adsorbing large machinery through the magnetic base. Among them, the structures of the vibration sensor 6 and the magnetic head 8 are all prior arts, which have been disclosed in a wireless vibration sensor with built-in antenna CN208921275U, and will not be repeated here.

[0029] The inside of the abutment block 12 is an arc surface, and the bottom end of the contact surface between the abutment block 12 and the vibration sensor 6 is chamfered so that the vibration sensor 6 can be squeezed into between the two abutment blocks 12 through the chamfered inclined surface.

[0030] Among them, the contact end of the buffer head 10 and the vibration sensor 6 is fixedly connected with a rubber head, which increases the friction between the buffer head 10 and the vibration sensor 6 and dilutes the force of external impact through the rubber head to reduce the impact on the vibration sensor 6. The first elastic member 9 and the second elastic member 11 are both springs.

[0031] Among them, the inner wall of the protective shell 2 is evenly coated with a thermal conductive material 13, adjacent heat sinks 4 are relatively inclined, and there are gaps between adjacent heat sinks 4. The thermal conductive material 13 uses thermal conductive silicone grease, and the heat in the protective shell 2 is transferred to the heat sink 4 through the thermal conductive material 13 to avoid excessive temperature accumulation of the protective shell 2 and affect the operation of the vibration sensor 6.

[0032] Among them, the bottom end of the protective shell 2 is threadedly connected with an adjustment ring 7, and the outer side of the adjustment ring 7 is fixedly connected with the base 1. By threading the protective shell 2 to connect the adjustment ring 7, the space of the protective shell 2 can be adjusted to adapt to vibration sensors 6 of different sizes.

[0033] Among them, the bottom end of the adjustment ring 7 is fixedly connected with a gasket 5, which isolates the external medium from entering the protective shell 2, reduces the oxidation corrosion of the surface of the vibration sensor by dust and water vapor in the external environment, and improves the service life of the device.

[0034] Among them, the four corners of the base 1 are each provided with mounting holes, and bolts 3 are threadedly connected in the mounting holes. The mounting holes at the four corners cooperate with the bolts 3 to fix the base 1 at the detected position.

[0035] The buffer head 10 and the two abutment blocks 12 are distributed in a triangular shape, and provide triangular support for the vibration sensor 6, so that the vibration sensor 6 is adsorbed within the detection range of the detected device, thereby improving the detection accuracy of the device.

[0036] Working principle: The base 1 is fixed at the detected position through the mounting holes at the four corners and the bolts 3. At this time, the vibration sensor 6 is placed in the protective shell 2 by manpower. The space of the protective shell 2 can be adjusted by the threaded connection adjustment ring 7 of the protective shell 2 to adapt to vibration sensors 6 of different sizes. When the device is impacted, the buffer head 10 is pushed inward by the first elastic member 9, and the vibration sensor 6 is squeezed inward by the buffer head 10, so that the vibration sensor 6 is always tightly adsorbed on the detected device, and the force of the external impact is diluted by the rubber head to reduce the impact on the vibration sensor 6. At the same time, the two second The elastic member 11 uses its own elasticity to squeeze the abutment block 12 inward at the same time, and the two abutment blocks 12 squeeze the middle part of the vibration sensor 6 inward at the same time, so that the vibration sensor 6 is adsorbed within the detection range of the detected device, thereby improving the detection accuracy of the device, and transferring the heat in the protective shell 2 to the heat sink 4 through the thermal conductive material 13 to avoid excessive temperature accumulation of the protective shell 2 and affecting the operation of the vibration sensor 6. The gasket 5 isolates the external medium from entering the protective shell 2, reducing the oxidation corrosion of the surface of the vibration sensor by dust and water vapor in the external environment, thereby increasing the service life of the device.
