Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
In the utility model, when not doing contrary explanation, the noun of locality of use as " upper and lower, top, the end " normally for direction shown in the drawings or for each parts mutual alignment relationship description word vertically, on vertical or gravitational direction.
As illustrated in figs. ia and ib, a kind of vibration sensor mounting base, vibration sensor mounting base is for being arranged on apparatus body, vibration sensor mounting base comprises Base body 1, Base body 1 is provided with the first mounting structure for being installed to by vibration sensor mounting base on apparatus body and is used for installing the second mounting structure of vibration transducer, Base body 1 is insulator.Second mounting structure makes vibration transducer can be connected with vibration sensor mounting base, thus is arranged on apparatus body.By vibration transducer is arranged on vibration sensor mounting base; and the Base body 1 of vibration sensor mounting base is insulator; make vibration sensor mounting base can avoid the oscillating signal saltus step because the reasons such as generator rotor ground is bad cause or occur that overvoltage is burnt vibration transducer and measures the situations such as module, the safety of protection unit.
If because the rigidity of Base body 1 is bad, then vibration transducer can produce weak vibrations, thus affects the measurement of vibration transducer.Therefore, especially, Base body 1 is rigid pipe.Base body 1 preferably insulate and has the ability of good opposing deformation, such as epoxy resin etc.
In the utility model, first mounting structure and the second mounting structure can be set to suitable form as required, as long as Base body 1 can be fixedly mounted on apparatus body by the first mounting structure, and by the second mounting structure, vibration transducer be fixedly mounted in Base body 1.Such as, can be spirally connected between Base body 1 and apparatus body and vibration transducer, rivet, clamping etc.
Especially, vibration sensor mounting base is arranged on apparatus body various ways, such as, as shown in Figure 2, first mounting structure can, for being arranged on the outside thread 1a of Base body 1 periphery, make vibration sensor mounting base be directly installed on apparatus body by the cooperation of screw thread 1a; Again as shown in Figure 1a, the first mounting structure can also be attachment hole, is connected by vibration sensor mounting base by link with apparatus body, thus vibration sensor mounting base is firmly fixed on apparatus body.
In addition, the utility model additionally provides a kind of Generator Vibration measuring device, and this device is comprised above-mentioned vibration sensor mounting base and is arranged on the vibration transducer on vibration sensor mounting base by the second mounting structure.Vibration transducer is arranged on vibration sensor mounting base; in particular; vibration sensor mounting base is insulator; make Generator Vibration measuring device avoid the oscillating signal saltus step because the reasons such as generator rotor ground is bad cause or occur that overvoltage is burnt vibration transducer and measures the situations such as module; protection Generator Vibration measuring device and unit safety, make the measurement of Generator Vibration measuring device more accurate simultaneously.
In a kind of mode of execution of the present utility model, the second mounting structure can be tapped hole 2, and the bottom of vibration transducer has the joint screw thread coordinated with tapped hole 2.As shown in Figure 2, in particular, tapped hole 2 is through hole, by coordinating of tapped hole 2 and joint screw thread, vibration transducer is firmly arranged on vibration sensor mounting base, thus vibration transducer is fixed on apparatus body closely, avoid because fix built on the sand, and the shock of the vibration transducer caused, thus it is inaccurate that vibration transducer is measured.
Especially, the second mounting structure is tapped hole 2, and vibration transducer is installed on tapped hole 2 by screw tightening.This mounting type is applicable to vibration transducer itself screw thread, by being arranged on tapped hole 2 by vibration transducer the screw thread on screw tightening and coordinating between the screw thread of tapped hole 2.
Vibration transducer directivity is installed, the profile of vibration transducer is generally based on cylindrical body, and its axis is consistent with direction of vibration, otherwise vibration transducer measures is the component of vibration, makes the result that measures inaccurate.Therefore the utility model provides two kinds of mode of executions, for measuring different direction of vibration, selects different vibration sensor mounting bases to be connected with vibration transducer and apparatus body.
Especially, in a kind of mode of execution of the present utility model, apparatus body is generator, apparatus body is provided with the threaded mounting hole for installing vibration sensor mounting base, first mounting structure is the outside thread 1a being arranged on Base body 1 periphery, and outside thread 1a coordinates with threaded mounting hole.As shown in Figure 2, apparatus body is by the outside thread 1a of Base body 1 and coordinating of the threaded mounting hole on apparatus body, vibration sensor mounting base can be arranged on apparatus body, and the vibration sensor mounting base in this mode of execution is more suitable for the vibration measurement of the transverse direction to apparatus body.
In another kind of mode of execution of the present utility model, apparatus body is generator, first mounting structure is the first attachment hole 4, apparatus body is provided with the second attachment hole, and apparatus body and vibration sensor mounting base are by being connected with the fastening piece 3 of the second attachment hole through the first attachment hole 4.As shown in Figure 1 b, such as fastening piece 3 can be bolt, first attachment hole 4 and the second attachment hole all have the screw thread of fitted bolt, by the screw-thread fit of bolt and the first attachment hole 4, second attachment hole, vibration sensor mounting base can be arranged on apparatus body, vibration sensor mounting base in this mode of execution can be placed on below vibration transducer, is applicable to the vibration measurement to the longitudinal direction of apparatus body.
Below preferred implementation of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
