[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0024] A gear disc speed measuring device for a hydro-turbine generator set comprises a mounting seat 1. An anti-skid pad 11 is fixed to the bottom of the mounting seat 1 by glue. The anti-skid pad 11 is made of rubber. A plurality of grooves 12 are arranged at even intervals at the bottom of the anti-skid pad 11 to prevent skidding.

[0025] Furthermore, a turntable 13 is provided on the left side of the mounting base 1 to drive the threaded rod 15 to rotate. A plurality of anti-skid grooves 14 are provided on the circumferential outer wall of the turntable 13. The anti-skid grooves 14 are evenly arranged at equal intervals to prevent skidding.

[0026] Specifically, a threaded rod 15 is fixedly connected to the right end of the turntable 13 by means of bolts. The threaded rod 15 is threadedly connected to the mounting seat 1 to drive the moving seat 16 to move.

[0027] Specifically, the right end of the threaded rod 15 is rotatably connected to the moving seat 16 via a bearing, and the bottom of the moving seat 16 is in contact with the bottom of the inner wall of the mounting seat 1 .

[0028] It should be added that a signal transceiver 17 is fixedly connected to the bottom of the inner wall of the movable seat 16 by bolts, and is used to send the signal received by the infrared receiver 19 to the computer terminal, and the computer terminal analyzes the time interval between each signal to know the rotation speed of the gear disk. A controller 18 is provided on the left side of the signal transceiver 17, and the controller 18 is fixedly connected to the bottom of the inner wall of the movable seat 16 by bolts, and is used to control the signal transceiver 17 to send signals to the computer terminal.

[0029] Specifically, an infrared receiver 19 is provided on the right side of the signal transceiver 17. The infrared receiver 19 is fixedly connected to the bottom of the inner wall of the movable seat 16 by bolts. The infrared receiver 19 is located directly below the transmitting end of the infrared transmitter 291 and is used to receive the infrared rays generated by the infrared transmitter 291 and send a signal to the controller 18 when the infrared rays are received.

[0030] As a preferred embodiment of the present invention, a mounting mechanism 2 is provided on the right side of the mounting seat 1 , and the mounting mechanism 2 includes a housing 21 , and the top of the housing 21 is fixedly connected to the top of the inner wall of the moving seat 16 by bolts to limit the moving direction of the slider 22 .

[0031] Specifically, a slider 22 is slidably connected to the inner wall of the housing 21 to limit the moving direction of the plug plate 23. The bottom of the slider 22 is fixedly connected to the plug plate 23 by bolts. The plug plate 23 is plugged into the inner wall of the slot 28 to limit the position of the limit plate 27.

[0032] Specifically, a pull rod 24 is fixedly connected to the top of the slider 22 by bolts to drive the slider 22 to move. The top of the pull rod 24 passes through the top of the moving seat 16 and is welded and fixed with a pull ring 25 to drive the pull rod 24 to move.

[0033] Specifically, springs 26 are symmetrically fixedly connected to the top of the slider 22 near the front and rear sides to limit the position of the slider 22 .

[0034] Specifically, a limit plate 27 is provided under the slider 22 , the left end of the limit plate 27 passes through the right end of the shell 21 and is slidably connected to the inner wall of the shell 21 , and a slot 28 is provided on the top of the limit plate 27 for cooperating with the plug plate 23 to limit the position of the limit plate 27 .

[0035] Specifically, an L-shaped mounting frame 29 is fixedly connected to the bottom of the limiting plate 27 near the right side by bolts for installing an infrared transmitter 291. The infrared transmitter 291 is fixedly connected to the bottom of the L-shaped mounting frame 29 by bolts. The user adjusts the position of the device so that the infrared rays emitted by the infrared transmitter 291 are blocked by the protruding teeth of the gear disc during the rotation of the gear disc and can be transmitted to the infrared receiver 19 through the gap between two adjacent protruding teeth.

[0036] It is worth mentioning that the structures and working principles of the signal transceiver 17, controller 18, infrared receiver 19 and infrared transmitter 291 involved in this embodiment are well known to those skilled in the art and will not be elaborated here.

[0037] During specific use, when the infrared transmitter 291 is damaged, the user first pulls the pull ring 25 upward, thereby driving the pull rod 24 to move upward, thereby driving the slider 22 to move upward, thereby driving the plug plate 23 to move upward. In this process, the slider 22 compresses the two springs 26;

[0038] When the two springs 26 are compressed to the shortest length, the plug plate 23 is no longer plugged into the inner wall of the slot 28, and the limit plate 27 is moved to the right until the outer wall of the limit plate 27 is no longer in contact with the housing 21, and the L-shaped mounting frame 29 with a new infrared emitter 291 is moved to the right side of the housing 21, driving the L-shaped mounting frame 29 to move to the left, thereby driving the limit plate 27 connected thereto to move to the left;

[0039] Until the left end of the limit plate 27 is inserted into the opening at the right end of the shell 21 and fits against the left surface of the inner wall of the shell 21, the pull ring 25 is released and the two springs 26 begin to restore their initial lengths, thereby driving the slider 22 to move downward, thereby driving the plug plate 23 to move downward, until the two springs 26 restore their initial lengths and the plug plate 23 is plugged into and matched with the inner wall of the slot 28, and the new infrared emitter 291 is installed.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
