Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0036] like Figure 1-Figure 6 As shown, the present application provides an online monitoring device for a motor, comprising a sealing assembly 10, and a support assembly 20 fixedly installed inside the sealing assembly 10, wherein the support assembly 20 is used to support and place the motor, and the support assembly 20 can perform online monitoring after the motor is placed. This monitoring work is done through The basic principle of the motor performance treatment under no-load condition is to apply rated voltage or a A variable voltage within a certain range is applied to the motor to allow it to run without load, and then various parameters of the motor are measured to evaluate the Estimate the performance of the motor, Thereby, data analysis can be performed on the motor, and the sealing component 10 is used to seal the entire support component 20, so that the support component 20 can avoid contact with excessive dust and debris outside during operation, thereby improving the monitoring effect of the device.

[0037] The sealing assembly 10 includes a main body 11, and the supporting assembly 20 includes two groups of sleeves 21 fixedly mounted on the main body 11, and a supporting plate 22 is fixedly mounted on the two groups of sleeves 21. The supporting plate 22 is provided with a groove (not shown), and the groove is adapted to the external structure of the motor, so that the motor can be clamped in the groove, and the motor is supported and placed on the supporting plate 22.

[0038] The support disk 22 is provided with a power supply module (not shown in the figure), which can drive the motor placed on the support disk 22, so that the motor shaft can rotate on the support disk 22, and a sensor (not shown in the figure) is installed on the support disk 22, which is used to monitor the motor. The sensor can be an acceleration sensor, a displacement sensor, etc., wherein the acceleration sensor can measure the acceleration value of the motor vibration, and by analyzing the acceleration signal, it can be determined whether the motor has problems such as imbalance, misalignment, bearing failure, etc., and the displacement sensor is used to measure the relative displacement of the motor components, monitor the operating status of the motor and the wear of the mechanical components.

[0039] At the same time, a motor 23 is fixedly installed inside the main body 11, and the motor 23 is located at the bottom of the sleeve 21. A fan blade 24 is fixedly installed on the output shaft of the motor 23. At the same time, a plurality of air outlet holes 25 are opened on the support plate 22, so that the motor 23 can be turned on to drive the fan blade 24 to rotate, so that the sensor and the motor on the support plate 22 can achieve a certain degree of heat dissipation effect. At the same time, the wind from the fan blade 24 will pass through the air outlet holes 25, so that the wind body can extend the distance, and the use effect of the fan blade 24 is also improved.

[0040] A cylinder 29 is fixedly installed on the main body 11, and a pressing piece 211 is fixedly installed on the output end of the cylinder 29. At the same time, the pressing piece 211 is close to the supporting plate 22. Two support rods 210 are slidably installed at both ends of the pressing piece 211. At the same time, the support rods 210 are fixedly installed on the main body 11. By starting the cylinder 29, the pressing piece 211 can be moved up and down, and the support rods 210 can improve the stability of the pressing piece 211 when it moves. When the pressing piece 211 moves downward, the pressing piece 211 will be close to the supporting plate 22, so that the pressing piece 211 can cover and press the motor on the supporting plate 22. The motor may become loose or fall due to vibration, collision, etc. during operation. The pressing piece 211 can reduce the safety hazards caused by the loosening of the device, such as collision with surrounding equipment or personnel, thereby ensuring the safety of equipment and personnel.

[0041] A drag chain 212 is provided on one side of the pressing plate 211, and the drag chain 212 can cooperate with the motor 23. The motor 23 needs to be connected to a power cord when in use, so that the drag chain 212 can wrap the power cord on the motor 23, thereby making the power cord of the motor 23 effectively protected and arranged.

[0042] The main body 11 is rotatably connected to a handle 26, and a support bar 27 is threadedly connected to the bottom of the handle 26. The support bar 27 is fixedly connected to the motor 23, and a support column 28 is slidably installed on the outer side of the support bar 27. The support column 28 can limit the support bar 27, so that the handle 26 can be rotated to allow the support bar 27 to move up and down, and then the movement of the support bar 27 can drive the position of the fan blade 24 to change. When the support bar 27 drives the fan blade 24 to move inside the sleeve 21, the electronic components and sensors on the support disk 22 can provide a more accurate and effective heat dissipation method; for example, at different stages or according to the operation of the electronic components and sensors, the support bar 27 drives the fan blade 24 to move to a specific position, so that the airflow blown out of the air outlet 25 can directly act on the electronic component area where the heat is more concentrated, thereby accelerating the heat dissipation, ensuring that the electronic components and sensors are always in a suitable operating temperature range, and ensuring their stable performance and service life.

[0043] Two groups of sliding doors 12 are slidably installed on the main body 11 near the support plate 22. The sliding doors 12 are installed in an alternating manner. At the same time, handles 13 are fixedly installed on the sliding doors 12, so that the handles 13 can be operated to slide the sliding doors 12 on the main body 11, and the sliding doors 12 can be opened or closed. When the sliding doors 12 are opened, the staff can place the motor on the support plate 22. When the sliding doors 12 are closed, the main body 11 can be sealed, thereby preventing external dust from contacting the motor, thereby improving the monitoring effect of the device.

[0045] For example, the sliding door 12 can avoid the problem of external environmental interference. In the working environment, there may be various electromagnetic devices. When the area around the motor is not sealed, the external electromagnetic field may interfere with the signal transmission and data acquisition of the monitoring device, causing deviations in the monitored motor operating parameters and affecting the judgment of the actual operating state of the motor. By setting the sliding door 12, these problems can be effectively solved;

[0046] The sliding door 12 also has certain safety features. For example, when the motor is running, its rotating parts and electrical parts are dangerous. If the surrounding is not sealed, people operating nearby or passing by may be injured by accidentally touching the rotating parts, or may be electrocuted due to leakage caused by electrical failure.

[0047] In addition, an unsealed environment will make the motor and monitoring device more susceptible to external factors and malfunction. For example, the increase in dust and dirt on the surface of the motor will increase the workload of cleaning and maintenance; when the monitoring device fails due to environmental influences, it will be more difficult to troubleshoot and repair the problem because more environmental factors need to be considered.

[0048] The main body 11 is provided with a plurality of slide grooves 14 , and the two slide doors 12 can be located in the slide grooves 14 , so that the slide grooves 14 can prevent the main body 11 from having too many gaps when in use, thereby greatly improving the use effect of the slide doors 12 .

When the movement of the sliding door 12 drives the convex groove 19 to move, the convex groove 19 will contact the protrusion 18, so that the protrusion 18 will be pushed into the convex groove 19 through the spring 110, so that the sliding door 12 can be fixed on the main body 11, thereby preventing the sliding door 12 from being positionally shifted when sealing on the main body 11, thereby greatly improving the stability of the sliding door 12 when in use. At the same time, the protrusion 18 can be separated on the convex groove 19, so that the sliding door 12 can be operated and moved on the main body 11.

[0051] At the same time, the fixing rod 112 extends out of the bottom of the main body 11, and a pedal 114 is fixedly installed at the bottom of the fixing rod 112. The pedal 114 can be stepped on, so that the staff can step on the pedal 114 to drive the fixing rod 112 to move downward. At this time, the protrusion 18 can also be separated at the protruding groove 19, so that the protrusion 18 can have a variety of operation modes, thereby improving the use effect of the sliding door 12, and the sliding door 12 is more labor-saving when opening by pressing downward and stepping on it.

[0052] The main body 11 is provided with a sealing door 15, and a plurality of partitions 16 are fixedly installed inside the main body 11 near the sealing door 15, on which parts or other materials can be placed, and the sealing door 15 is used to seal and protect the partition 16.
