[0024] Specifically, by pulling the pull ring 50513 on the first fixed block 5051, the clamping rod 5058 is retracted into the movable cavity 5056. After the two arc-shaped clamps 502 are closed, the insert block 5053 is automatically inserted into the slot 5055. The pull ring 50513 is released to allow the clamping rod 5058 to automatically engage with the clamping slot 5059 under the rebound of the spring 50511, thereby achieving locking and fixation of the two arc-shaped clamps 502 after closing, so that the arc-shaped clamps 502 and the mounting sleeve 501 can be firmly mounted on the underflow pipe 4. When removing the alarm mechanism 5, it is only necessary to pull the pull ring 50513 to retract the clamping rod 5058 into the movable cavity 5056, and then use the rotating shaft 503 to flip the two arc-shaped clamps 502 outward to open them, and then remove the mounting sleeve 501 from the underflow pipe 4, so that the alarm mechanism 5 can be quickly disassembled and assembled.

[0025] Embodiment 2

[0026] See also Figure 2 and Figure 3On the basis of the first embodiment, it is further obtained that a mounting groove 506 is opened on the mounting sleeve 501, a radar wave speed meter 507 is fixedly arranged in the mounting groove 506, a speed measuring port 508 is fixedly connected to the speed measuring end of the radar wave speed meter 507, the speed measuring port 508 penetrates the mounting groove 506 and extends to the rubber pad 504, a control panel 509 is fixedly arranged at one end of the mounting sleeve 501, and an alarm light 510 and an alarm horn 511 are fixedly arranged on the mounting sleeve 501 respectively; the radar wave speed meter 507, the alarm light 510 and the alarm horn 511 are all electrically connected to the control panel 509.

[0027] Specifically, by starting the radar wave velocimeter 507, the speed measuring end of the speed measuring port 508 can detect the liquid flow inside the underflow pipe 4 in real time. The flow rate detected by the radar wave velocimeter 507 is transmitted to the control panel 509 in real time for analysis and processing, and a judgment is made based on a pre-set normal flow rate range. If the detected flow rate is different from the normal flow rate, it means that a blockage has occurred in the underflow pipe 4. At this time, the control panel 509 starts the alarm light 510 and the alarm horn 511 to emit an audible and visual alarm to prompt relevant personnel to dredge the underflow pipe 4. If the flow rate in the underflow pipe 4 is normal, the hydrocyclone 1 can be kept in normal use.

[0028] In the actual operation process, the installation sleeve 501 is first sleeved on the underflow pipe 4, and then the two arc-shaped clamping plates 502 are rotated by the rotating shaft 503 to close the two arc-shaped clamping plates 502. Before the arc-shaped clamping plates 502 are closed, the pull ring 50513 on the first fixing block 5051 is pulled to retract the clamping rod 5058 into the movable cavity 5056. After the two arc-shaped clamping plates 502 are closed, the insert block 5053 on the second fixing block 5052 is automatically inserted into the slot 5055 on the first fixing block 5051, and the pull ring is released. 50513 enables the clamping rod 5058 to automatically pop out of the movable cavity 5056 under the rebound effect of the spring 50511 and pass through the insertion hole 5054 on the plug block 5053 to clamp with the clamping groove 5059, so as to realize the locking and fixing of the two arc-shaped clamping plates 502 after closing, so that the arc-shaped clamping plates 502 and the installation sleeve 501 can fasten and clamp the underflow pipe 4, so that the installation sleeve 501 can be stably sleeved on the underflow pipe 4, and at the same time, the setting of the rubber pad 504 can effectively prevent the installation sleeve 501 from slipping off the underflow pipe 4;

[0029] By starting the radar wave velocimeter 507, the velocity measuring end of the velocity measuring port 508 can detect the liquid flow inside the underflow pipe 4 in real time. The flow velocity detected by the radar wave velocimeter 507 is transmitted to the control panel 509 in real time for analysis and processing. The control panel 509 makes a judgment based on the preset normal flow velocity range. If the detected flow velocity is different from the normal flow velocity, it means that the underflow pipe 4 is blocked. At this time, the control panel 509 starts the alarm light 510 and the alarm speaker 511 to emit an audible and visual alarm to prompt the relevant personnel to dredge the underflow pipe 4. If the flow velocity in the underflow pipe 4 is normal, the hydrocyclone 1 can be kept in normal use.

[0030] When the alarm mechanism 5 needs to be removed, it is only necessary to pull the pull ring 50513 to retract the clamping rod 5058 into the movable cavity 5056, and then use the rotating shaft 503 to flip the two arc-shaped clamping plates 502 outward to release the clamping of the underflow pipe 4, and then remove the installation sleeve 501 from the underflow pipe 4.
