[0026] Embodiment 1

[0027] See also Figure 1-Figure 7 The utility model provides a technical solution: a wind turbine vibration monitoring device, comprising a unit equipment body 1, a vibration monitoring device body 2 is installed on the front side of the unit equipment body 1, a connecting cable 4 is installed on the top of the vibration monitoring device body 2, a vibration monitoring sensor 3 is installed on the top of the connecting cable 4, and a fixed block 10 is installed on the left and right sides of the vibration monitoring device body 2. Two extrusion blocks 14 are arranged on the inner wall of the fixed block 10, and a card block 11 is installed on the side where the upper and lower extrusion blocks 14 are separated. Card slots 7 are opened on the left and right sides of the front of the unit equipment body 1, and the left and right card blocks 11 are plugged into the inner wall of the card slot 7; the sides where the upper and lower extrusion blocks 14 are separated are both in contact with the inner wall of the card slot 7, so as to facilitate the card block 11 to be plugged into the inner wall of the card slot 7.

[0028] When disassembling, first press the extrusion blocks 14 on the upper and lower sides to move toward the middle of the fixed block 10, and drive the card blocks 11 on the upper and lower sides to move synchronously, and at the same time let them disengage from the card slot 7. At this time, pull the vibration monitoring device body 2 forward to make it disengage from the unit equipment body 1, so as to facilitate the disassembly of the vibration monitoring device body 2. Then, the operator inspects the vibration monitoring device body 2. After the inspection is completed, squeeze the upper and lower extrusion blocks 14 and plug them into the inner wall of the card slot 7. At the same time, release the extrusion block 14, so that the card block 11 is stuck to the inner wall of the card slot 7, so as to facilitate the operator to disassemble and assemble the vibration monitoring device body 2 for subsequent inspection. After the installation is completed, start the vibration monitoring device body 2, and monitor the unit equipment body 1 in real time through the vibration monitoring sensor 3, and transmit the detected data to the vibration monitoring device body 2 through the connecting cable 4, so as to facilitate the operator to view the vibration amplitude of the unit equipment body 1 in real time to ensure the safety of the unit equipment body 1 during operation.

[0029] Embodiment 2

[0030] On the basis of the first embodiment, in order to facilitate the reset of the card block 11 and to lock it to the inner wall of the card slot 7, a slide groove 15 is opened in the middle of the fixed block 10, and a fixed rod 16 is installed on the rear side of the slide groove 15, and a spring 17 is sleeved on the outer side of the fixed rod 16; the left and right side extrusion blocks 14 are slidably connected to the outer side of the fixed rod 16, and the two ends of the spring 17 are respectively installed on the side of the upper and lower side extrusion blocks 14 away from the card block 11, so that the elastic force of the spring 17 is used to drive the card block 11 to reset.

[0031] When installing the vibration monitoring device body 2, the operator inserts the extrusion block 14 into the inner wall of the card slot 7 and releases the extrusion block 14 at the same time. Due to the elastic force of the spring 17, the upper and lower extrusion blocks 14 are driven to move along the outer side of the fixing rod 16 to the upper and lower sides of the fixing block 10 respectively, and the card block 11 is simultaneously driven to move and be carded to the inner wall of the card slot 7, thereby facilitating the operator to disassemble and assemble the vibration monitoring device body 2 during maintenance, so as to improve the efficiency of its maintenance.

[0032] Embodiment 3

[0033] On the basis of the second embodiment, in order to facilitate the installation of the vibration monitoring device body 2 and improve its vibration reduction effect, fixing columns 6 are installed at the four rear corners of the vibration monitoring device body 2, and a rubber plate 5 is installed at the rear end of the fixing column 6. A plurality of mounting grooves 8 are opened on the front side of the unit equipment body 1, and the rubber plate 5 is inserted into the inner wall of the mounting groove 8.

[0034] When the vibration monitoring device body 2 is installed, the rubber plate 5 is inserted into the inner wall of the installation groove 8, and the rubber plate 5 and the vibration monitoring device body 2 are connected together by the fixing column 6, so as to facilitate the positioning of the installation position of the vibration monitoring device body 2 during installation, and through the setting of the rubber plate 5, the vibration of the vibration monitoring device body 2 on the outside of the unit equipment body 1 is reduced, thereby improving the service life of the vibration monitoring device body 2 and reducing the risk of damage to its internal parts.

[0035] Embodiment 4

[0036] On the basis of Example 3, in order to further improve the service life of the vibration monitoring device body 2 and reduce the risk of damage to the vibration monitoring device body 2, a connecting plate 12 is installed on the rear side of the vibration monitoring device body 2, and a plurality of rubber blocks 13 are installed on the rear side of the connecting plate 12. A plurality of mounting grooves 9 are opened in the middle of the unit equipment body 1; both sides of the rubber block 13 are set to arc surfaces, and when the rubber block 13 is pushed to the front side of the unit equipment body 1, the rubber block 13 is in an extruded deformation state, and the rubber block 13 is inserted into the inner wall of the mounting groove 9, so that the rubber blocks 13 are arranged in a horizontally distributed manner to improve the effect of reducing vibration, thereby improving the service life of the vibration monitoring device body 2.

[0037] First, during the process of installing the vibration monitoring device body 2 backward, the connecting plate 12 is driven to move backward synchronously, so that the rubber block 13 is plugged into the inner wall of the second installation groove 9, and when it contacts the front side of the unit equipment body 1, it is squeezed and deformed. At the same time, the two sides of the rubber block 13 are arc surfaces, which makes it convenient to install it on the inner wall of the second installation groove 9, and the rubber blocks 13 are arranged in a horizontal distribution, so as to play a certain buffering effect, thereby reducing the risk of damage to the vibration monitoring device body 2, so as to further improve its mitigation effect.

[0038] In actual use, when disassembling, first press the extrusion blocks 14 on the upper and lower sides to move toward the middle of the fixed block 10, and drive the card blocks 11 on the upper and lower sides to move synchronously, and at the same time let them disengage from the card slot 7. At this time, pull the vibration monitoring device body 2 forward to make it detach from the unit equipment body 1, so as to facilitate the disassembly of the vibration monitoring device body 2. Then, the operator inspects the vibration monitoring device body 2. After the inspection is completed, squeeze the upper and lower extrusion blocks 14 and plug them into the inner wall of the card slot 7. At the same time, release the extrusion block 14, so that the card block 11 is stuck to the inner wall of the card slot 7, so as to facilitate the operator to disassemble and assemble the vibration monitoring device body 2 for subsequent inspection. After the installation is completed, start the vibration monitoring device body 2, and monitor the unit equipment body 1 in real time through the vibration monitoring sensor 3, and transmit the detected data to the vibration monitoring device body 2 through the connecting cable 4, so as to facilitate the operator to view the vibration amplitude of the unit equipment body 1 in real time to ensure the safety of the unit equipment body 1 during operation.
