Description

Technical Field

[0001] This utility model relates to the field of vibration sensor technology, and in particular to a vibration sensor based on the Internet of Things. Background Technology

[0002] Vibration sensors are a key component in testing technology. Their main function is to receive mechanical quantities and convert them into proportional electrical quantities. As they are also electromechanical conversion devices, they are sometimes called transducers or vibration pickups. Currently, monitoring motor parameters, especially real-time monitoring of dynamic parameters, can effectively prevent motor failures, reduce equipment and personal injury, lower component wear, create conditions for energy conservation and consumption reduction, ensure balanced production organization, improve operating rates, obtain significant economic benefits, and improve the level of automation control of motors. The vibration value of motor bearings is one of the important dynamic parameters. In existing technologies, motor bearing vibration monitoring generally involves placing sensors on the motor bearing housing for measurement.

[0003] A search revealed that Chinese patent publication number CN216081762U discloses a motor-embedded vibration sensor based on the Internet of Things, including a housing, a movable collar sleeved on the outer side of the middle part of the housing, a connecting wire set at the center of the top of the housing, an installation head set at the center of the bottom of the housing, a bearing ring fixedly sleeved on the outer wall of the middle part of the movable collar, and a top seat fixedly connected to the top wall of the movable collar.

[0004] While the above solution has the advantage of providing stable support for the housing, in actual use, the housing is only cushioned by the stabilizing spring. When the vibration force generated by the internal components of the motor is transmitted to the stabilizing spring, it will cause the housing to shake up and down, affecting the normal operation of the vibration sensor.

[0005] Therefore, there is an urgent need to provide a vibration sensor based on the Internet of Things to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the above-mentioned prior art, which only uses a stabilizing spring to buffer the housing in actual use. When the vibration force generated by the internal components of the motor is transmitted to the stabilizing spring, it will cause the housing to shake up and down, affecting the normal operation of the vibration sensor. This invention provides a vibration sensor based on the Internet of Things.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing a vibration sensor based on the Internet of Things, including a sensor housing, a wire installed on the top of the sensor housing, and a mounting assembly provided on the outside of the sensor housing;

[0008] The mounting assembly includes a movable ring movably disposed on the outside of the sensor housing, an adjustment unit disposed on the outside of the movable ring, a connection unit disposed on the inside of the movable ring, and a shock-absorbing unit disposed on the side of the connection unit.

[0009] The present invention is further configured such that a threaded post is installed at the bottom of the sensor housing.

[0010] The present invention is further configured such that: an annular protrusion is integrally formed on the outer side of the sensor housing, and the annular protrusion is located above the movable ring;

[0011] The movable ring consists of an inner ring and an outer ring, and a connecting frame is installed between the inner ring and the outer ring.

[0012] The present invention is further configured such that: there are two sets of adjustment units, and the two sets of adjustment units are arranged opposite to each other on the outer side of the movable ring;

[0013] The adjustment unit includes a fixed shell installed on the outer surface of the outer ring, a threaded rod threaded to the top surface of the fixed shell, and one end of a pressing rod movably connected to the bottom of the threaded rod. An arc-shaped clamp is installed at the other end of the pressing rod.

[0014] The present invention is further configured such that: there are multiple sets of the connecting units, and the multiple sets of the connecting units are distributed in a circular array with the center point of the movable ring as the center;

[0015] The connecting unit includes a fixed seat installed on the outer side of the inner ring, a movable rod movably disposed in the middle of the fixed seat, a fixed ring installed on the outer side of the movable rod, a first damping block installed on the side of the fixed ring, a second damping block installed on the side of the fixed seat, and a buffer disposed between the second damping block and the first damping block.

[0016] The present invention is further configured such that: a limit block is installed at one end of the movable rod, and a connecting plate is installed at the other end of the movable rod, and the top surface of the connecting plate is provided with an installation hole.

[0017] The present invention is further configured such that: the shock absorption unit includes a ring body installed on the outside of the movable rod and a weakening portion disposed between the ring body and the sensor housing;

[0018] The weakening part includes a fixed cylinder installed on the side of the ring body opposite to the sensor housing, a first buffer pad installed inside the fixed cylinder, one end of a buffer column movably disposed inside the fixed cylinder, a second buffer pad installed at the other end of the buffer column, the second buffer pad being installed on the outer surface of the sensor housing, and a shock-absorbing component being provided on the outside of the buffer column.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model uses an installation assembly to place the sensor housing in the middle of the internal bearing of the motor. It is threadedly installed with the threaded column and the bearing inside the motor. One end of the movable rod in the connecting unit abuts against the outer shell of the internal component of the motor. The movable rod is fixedly connected to the outer shell of the internal component by the connecting plate and its mounting hole. Then, by rotating the threaded rod, it pushes the extrusion rod to drive the arc-shaped clamping plate to abut against the outer surface of the internal bearing of the motor, thereby limiting the position of the sensor housing.

[0021] When the motor operates, the force generated causes the sensor housing to vibrate. The elastic action of the first damping block, the second damping block, and the buffer reduces the vibration force in the first stage. The first buffer pad, the second buffer pad, the buffer column, and the shock absorber set on the outside of the buffer column further reduce the vibration force, preventing the sensor housing from shaking and loosening due to vibration after installation, and ensuring the normal operation of the sensor housing and its internal components.

[0032] The movable ring 31 consists of an inner ring 311 and an outer ring 312, and a connecting frame is installed between the inner ring 311 and the outer ring 312.

[0033] There are two sets of adjustment units 32, which are arranged opposite to each other on the outside of the movable ring 31.

[0034] The adjustment unit 32 includes a fixed shell 321 installed on the outer surface of the outer ring 312, a threaded rod 322 threadedly connected to the top surface of the fixed shell 321, and one end of a pressing rod 323 movably connected to the bottom of the threaded rod 322. The other end of the pressing rod 323 is equipped with an arc-shaped clamping plate 324. Preferably, a protective pad is installed on the inner surface of the arc-shaped clamping plate 324. The protective pad is made of rubber.

[0035] Among them, there are multiple sets of connection units 33, and the multiple sets of connection units 33 are distributed in a circular array with the center point of the active ring 31 as the center;

[0036] The connecting unit 33 includes a fixed seat 331 installed on the outside of the inner ring 311, a movable rod 332 movably disposed in the middle of the fixed seat 331, a fixed ring 333 installed on the outside of the movable rod 332, a first damping block 334 installed on the side of the fixed ring 333, a second damping block 335 installed on the side of the fixed seat 331, and a buffer 336 disposed between the second damping block 335 and the first damping block 334. Preferably, the buffer 336 is a buffer spring, and the first damping block 334 and the second damping block 335 are both made of elastic rubber.

[0037] One end of the movable rod 332 is equipped with a limit block, and the other end of the movable rod 332 is equipped with a connecting plate, and the top surface of the connecting plate is provided with an installation hole.

[0038] The shock absorption unit 34 includes a ring body 341 installed on the outside of the movable rod 332 and a weakening part 342 disposed between the ring body 341 and the sensor housing 1. Preferably, there are four sets of weakening parts 342, and the four sets of weakening parts 342 are distributed in a ring at the bottom of the ring body 341.

[0039] The weakening part 342 includes a fixed cylinder 3421 installed on the side of the ring 341 opposite to the sensor housing 1, a first buffer pad 3422 installed inside the fixed cylinder 3421, and one end of a buffer column 3423 movably disposed inside the fixed cylinder 3421.

The vibration force is further reduced by the first buffer pad 3422, the second buffer pad 3424, the buffer column 3423, and the shock absorber 3425 located outside the buffer column 3423. This prevents the sensor housing 1 from shaking and loosening due to vibration after installation, ensuring the normal operation of the sensor housing 1 and its internal components.
