[0019] 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.

[0020] Reference Figure 1-Figure 3 A fermentation tank permanent magnet synchronous motor speed monitoring mechanism includes a motor body 1. A mounting box 2 is provided on the top of the motor body 1. A speed sensor 3 is installed on the side wall of the mounting box 2 through a telescopic adjustment component. The speed sensor 3 is located above the output shaft of the motor body 1. When monitoring the speed of the motor body 1, the monitored speed information can be transmitted to an external host to let the technician know.

[0021] The telescopic adjustment component includes a fixing frame 9 fixedly connected to the side wall of the mounting box 2, and an adjustment plate 10 is slidably inserted at one end of the fixing frame 9 away from the motor body 1. The top of the fixing frame 9 is threadedly connected with a fastening bolt 11 whose end is tightly pressed against the surface of the adjusting plate 10. The speed sensor 3 is fixedly installed at the bottom of the adjusting plate 10. When the speed sensor 3 monitors the speed of the motor body 1, the adjusting plate 10 can be pulled outward or pushed inward. When the speed sensor 3 moves to a specified position, the fastening bolt 11 is tightened so that its end is pressed against the surface of the adjusting plate 10 to fix the position of the adjusting plate 10 and the speed sensor 3. The monitoring position of the speed sensor 3 on the speed of the motor body 1 can be adjusted according to actual needs, thereby improving the practicability of the device.

[0022] A clamping assembly is provided between the mounting box 2 and the motor body 1, and the clamping assembly includes a bidirectional threaded rod 4 fixedly connected and rotatably installed in the mounting box 2. Bearings are fixedly sleeved on the outer walls at both ends of the bidirectional threaded rod 4, and the outer ring of each bearing is fixedly connected to the inner wall of the mounting box 2, so that the bidirectional threaded rod 4 can be more stable when rotating.

[0023] The surface of the bidirectional threaded rod 4 is reversely threadedly connected to two clamping plates 6, and the bottom of the mounting box 2 is symmetrically provided with two through holes 13 matching the clamping plates 6. The bottom of the mounting box 2 and the opposite sides of the two clamping plates 6 are fixedly connected with a plurality of heat dissipation strips 12, and each heat dissipation strip 12 is in contact with the surface of the motor body 1, so that there are gaps between the mounting box 2 and the two clamping plates 6 and the surface of the motor body 1, so that the surface temperature of the motor body 1 can be effectively dissipated when the motor body 1 is working, thereby extending the service life of the motor body 1 to a certain extent.

[0024] The first bevel gear 5 is meshed with the second bevel gear 7 on the upper side of the first bevel gear 5. Each clamping plate 6 movably passes through the inner bottom wall of the mounting box 2, and the two clamping plates 6 are respectively located on both sides of the motor body 1. A knob 8 is movably provided on the top of the mounting box 2. The center of the knob 8 and the second bevel gear 7 are fixedly connected with a rotating shaft, and the rotating shaft movably passes through the top of the mounting box 2. During installation, the two clamping plates 6 are respectively clamped on both sides of the motor body 1, and then the knob 8 is rotated to drive the second bevel gear 7 to rotate. Then, through the first bevel gear 5 meshed therewith, the two-way threaded rod 4 can be driven to rotate, so that the two clamping plates 6 move toward each other until they are tightly against the surface of the motor body 1, so that the speed sensor 3 can be installed and fixed, which is convenient for the installation and disassembly of the speed sensor 3 for maintenance and replacement. At the same time, it can also adapt to the speed monitoring of motors of different sizes, thereby improving the adaptability of the device.

[0025] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0026] 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.
