[0024] This utility model provides, for example Figures 1-6 The semi-autogenous motor intelligent monitoring and evaluation device shown includes a housing 1, on which a rotating shaft 2 is mounted. An outer cover 3 is fixedly connected to one end of the housing 1, and the outer cover 3 has a through groove for the rotating shaft 2 to pass through. A first fixing ring 4 is fixedly connected to the rotating shaft 2, located inside the outer cover 3. An infrared transmitter 5 is fixedly mounted on the outer wall of the first fixing ring 4, and an infrared receiver 6 is fixedly connected to the inner wall of the outer cover 3. The infrared transmitter 5 and the infrared receiver 6 cooperate with each other, and the outer cover 3 protects the infrared transmitter 5 and the infrared receiver 6.
[0025] By setting up structures such as an infrared transmitter 5 and an infrared receiver 6, during the operation of the semi-autogenous mill, the motor rotates, causing the shaft 2 to rotate. The shaft 2 drives the first fixed ring 4 to rotate and activates the infrared transmitter 5. The infrared transmitter 5 then rotates and continuously emits an infrared beam. Each time the infrared transmitter 5 aligns with the infrared receiver 6, the infrared receiver 6 receives the infrared beam, thereby monitoring the number of rotations of the shaft 2 and calculating the rotational speed based on the running time, thus assessing whether there are any abnormalities in the motor's operation.
[0026] In practical use, mobile terminals can be set up to work with infrared transmitter 5 and infrared receiver 6 for remote control. Rotation speed calculation is a common existing technology and will not be elaborated here.
[0027] To improve the heat dissipation of the motor and ensure the normal operation of the semi-autogenous mill, a second fixing ring 11 is fixedly connected to the end of the rotating shaft 2 away from the outer cover 3. Multiple circular holes 18 are formed on the outer wall of the second fixing ring 11 and are evenly distributed around it. A rotating rod 14 is rotatably connected inside each circular hole 18, and a fan blade 12 is fixedly connected to one end of the rotating rod 14 outside the circular hole 18. An inner groove 13 corresponding to and communicating with the circular hole 18 is formed inside the second fixing ring 11, and the rotating rod 14 extends into the inner groove 13. A strip 15 is provided inside the inner groove 13 and is fixedly connected to the rotating rod 14.
[0028] A magnetic block 16 is fixedly connected to the side wall of the strip 15, and an electromagnet 17 is fixedly connected to the inner wall of the inner groove 13. The magnetic block 16 and the electromagnet 17 cooperate with each other. A power supply device (not shown in the figure) can be set on the second fixing ring 11 to supply power to the electromagnet 17. The power supply device includes a battery and other structures. The power supply device is a common existing technology and will not be described in detail here.
[0029] The second fixing ring 11 is provided with a fan cover 9 on its outside. The end of the fan cover 9 away from the housing 1 is provided with several air holes. The fan cover 9 is fixedly connected to the housing 1. A flow sensor 10 is fixedly installed on the inner wall of the fan cover 9. The flow sensor 10 is used to monitor the air volume passing through the fan cover 9.
[0030] Specifically, a controller can be configured to connect between the electromagnet 17 and the flow sensor 10. The controller and its control principle are common existing technologies and will not be described in detail here.
[0031] Under normal conditions, when electromagnet 17 is activated, the magnets on the sides of the magnetic block 16 and electromagnet 17 that are close to each other become opposite in magnetism. Under the action of mutual attraction, the angle of the fan blade 12 is fixed by the strip plate 15 and the rotating rod 14. The motor drives the fan blade 12 to rotate through the rotating shaft 2 and the second fixing ring 11. The airflow is directed from the fan cover 9 toward the housing 1, allowing external air to pass through the fan cover 9 and enter the interior of the housing 1, ensuring heat dissipation. The fan cover 9 can also filter impurities. At the same time, impurities will accumulate on the outside of the fan cover 9 due to attraction, affecting the airflow and reducing the heat dissipation effect.
[0032] When the flow sensor 10 detects that the airflow through the fan shroud 9 exceeds or falls below a set threshold, it transmits this information to the controller. The controller controls the electromagnet 17 so that the magnetic properties of the magnetic block 16 and the electromagnet 17 on their adjacent sides are the same. Under the action of repulsive force, the angle of the fan blade 12 is adjusted through the strip 15 and the rotating rod 14. When the motor drives the fan blade 12 to rotate through the rotating shaft 2 and the second fixed ring 11, and the airflow is from the casing 1 towards the fan shroud 9, the generated airflow will blow back the impurities accumulated on the outside of the fan shroud 9, assisting the operator in cleaning and achieving intelligent processing. Then, the electromagnet 17 is controlled again so that the magnetic properties of the magnetic block 16 and the electromagnet 17 on their adjacent sides are opposite, and heat dissipation continues.
[0033] Furthermore, a vent hole (not shown in the figure) can be provided at the end of the housing 1 away from the fan shroud 9 to ensure gas flow.
[0034] By setting up structures such as the rotating rod 14 and the fan blades 12, external air can pass through the fan cover 9 and enter the interior of the housing 1, ensuring heat dissipation. The angle of the fan blades 12 is adjustable, which can blow back the impurities accumulated on the outside of the fan cover 9, assisting the operator in cleaning, ensuring heat dissipation, and improving the operating efficiency of the motor.
[0035] A device box 7 is fixedly connected to the top of the housing 1. A temperature sensor 8 is fixedly installed inside the device box 7. The temperature sensor 8 is used to monitor the temperature inside the housing 1. By setting the temperature sensor 8, the temperature inside the housing 1 can be intelligently monitored, which makes it easier for operators to evaluate the operation of the motor.
