[0026] As Figures 1-5 shown, a wireless vibration monitoring sensor for a water pump includes a mounting structure 10 and a connecting structure 20. The mounting structure 10 includes two symmetrically arranged clamping blocks. The clamping block includes an arc-shaped clamping part 11 and a connecting part 12 arranged on one side of the clamping part 11. The connecting parts 12 are arranged in parallel. The distance between the two clamping parts 11 gradually increases in the direction away from the connecting part 12, which is convenient for clamping the edge of the water pump 50. The connecting parts 12 can be connected by two pairs of bolts. Two first screw holes are provided on the clamping part 11. First screws 13 are respectively passed through the first screw holes. One end of the first screw 13 located between the two clamping parts 11 is rotatably connected with a friction block 14. Friction teeth are provided on the opposite surfaces of the friction block 14. The connecting structure 20 is arranged on one of the connecting parts 12 and includes a connecting plate 21 and a protective shell 22 arranged on the connecting plate 21. A sensor body 30 for monitoring vibration is arranged in the protective shell 22. A ventilation hole is provided at the bottom of the protective shell 22, and a waterproof and breathable membrane 23 is arranged at the ventilation hole, which takes into account waterproofing and ventilation at the same time. The sensor body 30 is connected to the existing monitoring equipment.

[0027] The working principle of the above technical solution is as follows:

[0028] The distance between the connecting parts 12 can be initially adjusted by bolts to change the distance between the clamping blocks. After adjustment, the connection between the clamping part 11 and the connecting part 12 abuts against the edge of the water pump 50. The clamping part 11 can be close to both sides of the edge of the water pump 50. By rotating the first screw 13, the two friction blocks 14 can clamp the water pump 50, and the mounting structure 10 is fixed on one side of the water pump 50. Since it is installed on the edge of the water pump 50, the mounting structure 10 is close to the water pump 50, and the influence on the installation of the water pump 50 is small. And the connecting structure 20 is connected to one of the connecting parts 12, so that the sensor body 30 in the protective shell 22 is close to the water pump 50. On the basis of the stable connection of the mounting structure 10, the vibration generated by the water pump 50 can be accurately received, and it is convenient to adjust through the first screw 13 and bolts for installation on water pumps 50 of different specifications.

A second screw 43 is provided at the bottom of the movable block 41, and a second screw hole 44 matching the second screw 43 is provided at the top of the support block 42. The overall height of the support base 40 can be adjusted by rotating the movable block 41 according to different water pumps 50. When rotating, based on one circle, ensure that the clamping part 11 of the installation structure 10 always faces the water pump 50.

[0030] In another embodiment, as shown in Figure 5 , a connection hole matching the protective shell 22 is provided in the middle of the connection plate 21. A clamping plate 24 with a size larger than the connection hole is provided at the top of the protective shell 22. The protective shell 22 is passed through the connection hole, and the bottom surface of the clamping plate 24 is attached to the top surface of the connection plate 21; insertion holes 25 are provided around the connection hole of the connection plate 21, and insertion rods 26 matching the insertion holes 25 are provided at the bottom surface of the clamping plate 24. The protective shell 22 is convenient for disassembly and installation, realizing the convenient disassembly and installation of the sensor main body 30. After the provided insertion rods 26 and insertion holes 25 are connected, the connection stability between the protective shell 22 and the connection plate 21 can be improved.

[0031] In another embodiment, as shown in Figures 1-2 , an installation plate 45 is provided on the outside of the support block 42, and an installation hole 46 for connecting the water pump 50 is provided on the installation plate 45. The installation plate 45 of the support block 42 can utilize the holes on the existing base of the water pump 50.
