Description

Technical Field

[0001] This utility model relates to the field of power plant inspection equipment, and in particular to an inspection device for power plant equipment. Background Technology

[0002] A vibration meter is a specialized instrument used to measure the vibration parameters of equipment. Its main function is to determine the operating status of the equipment, identify potential faults, and assess the health status of the equipment by analyzing the amplitude, frequency, phase, and other characteristics of the equipment vibration.

[0003] A search revealed Chinese Patent Publication No. CN215448185U, which discloses a portable intelligent vibration meter, comprising a vibration meter body and a protective cover detachably mounted on one end of the vibration meter body. The vibration meter body has a mounting cavity, within which a control component extending outwards is detachably connected. A sensor, electrically connected to the control component, is detachably connected within the mounting cavity. A probe housed within the protective cover is detachably connected to the extended end of the sensor. The probe is electrically connected to the sensor. A first storage cavity is located at the bottom of the vibration meter body on the side away from the protective cover. Second storage cavities are located on both sides of the first storage cavity. A spiral connecting wire and a telescopic component are respectively housed within each of the two second storage cavities. The ends of the spiral connecting wire and the telescopic component correspond to the sensor and the probe, respectively. A cover plate, hinged to the end of the vibration meter body away from the protective cover, engages with the first storage cavity. This utility model uses a button and a U-shaped spring to engage the teeth and slots under the elastic action of the spring, thereby detachably connecting the protective cover to the vibration meter body. The protective cover can encapsulate and protect the test end of the vibration meter body, extending the service life of the sensor and preventing the sensor's testing accuracy from being affected by impurities.

[0004] In the above-mentioned technology, although the engagement of the locking teeth and the locking slot is achieved by the cooperation of the button and the U-shaped spring, thereby detachably connecting the protective cover and the vibration meter body, the button setting poses a chance of accidental activation during carrying, resulting in the loss of the protective cover. Therefore, an inspection device for power plant equipment is proposed to solve the above problems. Utility Model Content

The inclined surface of the locking block 8 is squeezed by the protective cover 3, and the locking block 8 retracts into the fixed base 2, squeezing the spring 12. After the protective cover 3 is installed in place, the locking block 8 pops out under the elastic force of the spring 12 and locks into the protective cover 3 to fix its position (by pushing the moving block 11, the movement of the moving block 11 drives the moving rod 13 to move vertically, so that the locking block 8 leaves the inner wall of the protective cover 3 and enters the fixed base 2, thus releasing the fixation of the protective cover 3 and removing the protective cover 3). Then pull the clamping block 4 outward. The movement of the clamping block 4 drives the connecting rod 6 and the moving plate 7 to move, squeezing the spring 5, locking the clamping block 4 onto the frame, releasing the clamping block 4, so that instrument 1 is clamped on the frame to fix instrument 1, which is convenient for carrying during inspection.
