Description

Technical Field

[0001] The present invention relates to an auxiliary device for building mechanical and electrical installation and a method thereof, and particularly to a building mechanical and electrical installation base with a shaking detection function and a shaking detection method thereof. Background Art

[0002] During the construction process of building projects, the installation and use of mechanical and electrical equipment are often involved. In order to ensure the stable installation and use of mechanical and electrical equipment, most workers will place the mechanical and electrical equipment on the installation base, fix and combine the mechanical and electrical equipment with the installation base by means of bolts, etc., and then fix and install the installation base at the designated position by means of bolts, etc. Since mechanical and electrical equipment such as motors and motors will generate a certain degree of vibration during operation, after long-term use, the bolts may become loose due to the vibration force, resulting in the installation base shaking under the action of vibration, thereby causing the mechanical and electrical equipment to be unstable, affecting the use safety and life of the mechanical and electrical equipment.

[0003] At present, the inspection of mechanical and electrical equipment and its installation base is mostly completed manually. Workers regularly detect the tightness of the bolts connecting the mechanical and electrical equipment and the installation base. However, tools need to be carried during the detection process, which wastes manpower and is also more cumbersome in the detection work, greatly reducing the work efficiency. At the same time, it often happens that the bolts connecting the mechanical and electrical equipment and the installation base become loose due to human detection negligence. Therefore, there is a need to provide a device and method that can stably install mechanical and electrical equipment and can quickly and intuitively detect the shaking condition of the installation base.

[0040] 1. Since the present invention is provided with a clamping mechanism and an anti-loosening mechanism, it can complete the clamping and fixing of electromechanical equipment of different models and sizes. After the clamping mechanism clamps and fixes the electromechanical equipment, the anti-loosening mechanism can be operated to limit the clamping mechanism. At the same time, the electromechanical equipment is limited by the placement groove, avoiding the loosening of the bolt connection caused by the vibration of the electromechanical equipment during operation, resulting in unstable installation of the electromechanical equipment. It can also prevent the installation base from shifting and shaking due to the loosening of the fixing bolts during long-term operation. The disassembly of mechanical equipment is convenient and fast.

[0041] 2. Since the present invention is provided with a detection mechanism, when the installation base shakes, it can quickly and intuitively judge the amplitude of the shake, and thus judge whether the bolts are loose. The observation of the transparent detection box is relatively intuitive, and people passing by can see the vibration state of the installation base, which is convenient for improving the timeliness of maintenance. It can also avoid the inconvenience of maintenance personnel regularly carrying maintenance tools to detect the installation base, greatly improving work efficiency and saving certain human and material costs.

Detailed implementation manners

[0056] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0057] Please refer to the attachedFigure 1 and the attached Figure 2 , a building mechanical and electrical installation base with a shaking detection function, including an installation base 100, lower bolts 300, a detection mechanism 500, a clamping mechanism 600, an anti-loosening mechanism 700, and a repulsive force mechanism 900; a plurality of lower bolt holes 200 are formed at the bottom of the installation base 100, so that the installation base 100 is installed and fixed through a plurality of lower bolts 300 via the lower bolt holes 200; a placement groove 400 is formed at the top of the installation base 100, and the bottom of the mechanical and electrical equipment 800 is embedded in the placement groove 400, and a plurality of groups of clamping mechanisms 600 are respectively arranged at intervals on the top of the installation base 100 and symmetrically press and clamp on both sides of the mechanical and electrical equipment 800; a plurality of groups of anti-loosening mechanisms 700 are respectively arranged at intervals on the top of the installation base 100, and the anti-loosening mechanisms 700 can be movably sleeved on the clamping mechanisms 600; the detection mechanism 500 is arranged in the installation base 100 and below the mechanical and electrical equipment 800, and a plurality of groups of repulsive force mechanisms 900 are respectively embedded at the ends of the installation base 100 and outside the detection mechanism 500.

[0058] The size of the installation base 100 and its placement groove 400 can be determined according to the weight and size of the mechanical and electrical equipment 800; the number of the lower bolt holes 200 is the same as that of the lower bolts 300, and the number can be determined according to the size of the installation base 100, the weight of the mechanical and electrical equipment 800, and its vibration condition; the number of the clamping mechanisms 600 can be determined according to the size of the mechanical and electrical equipment 800. Preferably, two groups of clamping mechanisms 600 can be symmetrically arranged on both sides of the mechanical and electrical equipment 800, and the number of the anti-loosening mechanisms 700 can be determined according to the number of the clamping mechanisms 600 to ensure that the anti-loosening mechanisms 700 can effectively limit the loosening of the clamping mechanisms 600; two groups of repulsive force mechanisms 900 can be arranged, symmetrically located on both sides of the detection mechanism 500.

[0059] After the mechanical and electrical equipment 800 is installed in the placement groove 400 of the installation base 100, the clamping and fixing of mechanical and electrical equipment 800 of different models and sizes can be completed by adjusting the clamping mechanism 600, and the applicability is relatively strong. When the clamping mechanism 600 clamps and fixes the mechanical and electrical equipment 800, the clamping mechanism 600 can be limited by operating the anti-loosening mechanism 700 to avoid the phenomenon that the clamping mechanism 600 loosens under the action of the vibration of the mechanical and electrical equipment 800 during operation, resulting in unstable installation of the mechanical and electrical equipment 800. In order to prevent the installation base 100 from shifting and shaking due to the loosening of the fixing bolts during the long-term operation of the mechanical and electrical equipment 800, through the provided detection mechanism 500, when the installation base 100 shakes, the amplitude of the current shake can be judged, so as to know whether bolts such as the lower bolts 300 are loose.

[0060] Please refer to the attached Figure 3 and the attached Figure 4, each of the clamping mechanisms 600 includes a mounting gasket 601, an upper bolt 604, a pressing slider 605, a clamping slider 607, a limiting block 608, a compression spring 6010, a clamping plate 6011, and a deformable airbag 6012; the mounting gasket 601 is arranged on the mounting base 100, and a threaded groove 602 is formed on the mounting gasket 601. A sliding groove 603 communicating with the threaded groove 602 is formed in the mounting base 100, so that the lower part of the upper bolt 604 can be screwed into the threaded groove 602 and inserted into the sliding groove 603. The anti-loosening mechanism 700 is sleeved on the upper part of the upper bolt 604; the sliding groove 603 is in an L-shaped structure, and the pressing slider 605 is fitted in the vertical section of the sliding groove 603 and fixedly connected with the upper bolt 604; the clamping slider 607 is fitted in the horizontal section of the sliding groove 603. One end of the clamping slider 607 penetrates through the mounting base 100 and is connected with the clamping plate 6011, and the clamping plate 6011 can be attached to the outer wall of the electromechanical device 800; the deformable airbag 6012 is arranged at the corner of the sliding groove 603, the pressing slider 605 can press on the pressing end of the deformable airbag 6012, and the expanding end of the deformable airbag 6012 can be in contact connection with the other end of the clamping slider 607; a limiting groove 609 parallel to the clamping slider 607 is formed on the horizontal section of the sliding groove 603. One end of the compression spring 6010 is fixed at one end of the limiting groove 609 close to the deformable airbag 6012, the other end of the compression spring 6010 is fixedly connected with the limiting block 608, and the limiting block 608 is fixedly arranged on the clamping slider 607.

[0061] Preferably, the pressing slider 605 is in sliding contact with the inner wall of the sliding groove 603. The vertical section of the sliding groove 603 can adopt a cylindrical structure to ensure that the pressing slider 605 slides downward under the drive of the upper bolt 604 and presses the deformable airbag 6012, so that the expanding end of the deformable airbag 6012 expands and pushes the clamping slider 607 to slide outward, so that the clamping plate 6011 can be attached and pressed on the electromechanical device 800 to achieve the purpose of clamping and fixing. The cross-section of the clamping slider 607 and the horizontal section of the sliding groove 603 can be a rectangular structure to ensure the horizontal stable sliding of the clamping slider 607. While the clamping slider 607 slides outward, the limiting block 608 slides synchronously along the limiting groove 609, and the compression spring 6010 is stretched. If it is necessary to disassemble the electromechanical device 800, the upper bolt 604 can be screwed out upward to separate the pressing slider 605 from the deformable airbag 6012. Under the elastic force of the compression spring 6010, the limiting block 608 slides back to its original position and drives the clamping slider 607 to retract inward synchronously, thereby pushing the deformable airbag 6012 to restore its shape.

[0062] Please refer to the appendix Figure 4 , an anti-slip pad 606 is provided at the bottom of the pressing slider 605, and the pressing slider 605 can press on the deformable airbag 6012 through the anti-slip pad 606.

[0063] Preferably, the anti-slip mat 606 can be made of rubber material to play an anti-slip role, so as to ensure that the pressing slider 605 can fully squeeze and deform the airbag 6012.

[0064] Please refer to the appendix Figure 5 The deformable airbag 6012 includes an elastic outer shell 6013, inert gas 6014, and an expansion airbag 6015. The elastic outer shell 6013 is arranged in the vertical section of the chute 603 and can be in contact connection with the pressing slider 605. The inert gas 6014 is filled in the elastic outer shell 6013. The expansion airbag 6015 is arranged on one side of the elastic outer shell 6013 and is located in the horizontal section of the chute 603. The expansion airbag 6015 can be in contact connection with the other end of the pressing slider 607. The elastic outer shell 6013 is formed with air vents 6016 to communicate the elastic outer shell 6013 with the expansion airbag 6015.

[0065] When the top of the elastic outer shell 6013 is squeezed by the pressing slider 605, the inert gas 6014 in the elastic outer shell 6013 enters the expansion airbag 6015 through the air vents 6016, causing the expansion airbag 6015 to inflate and expand. The expansion of the expansion airbag 6015 is used to push the pressing slider 607 to slide outwards. The elastic outer shell 6013 and the expansion airbag 6015 can be made of elastic materials such as rubber to ensure that their deformation amplitude can meet the requirements of the extension distance.

[0066] Please refer to the appendix Figure 6 The anti-loosening mechanism 700 includes a first telescopic rod 701, a second telescopic rod 702, and a limiting collar 703. The lower end of the first telescopic rod 701 is arranged on the mounting base 100. One end of the second telescopic rod 702 is rotatably connected to the upper end of the first telescopic rod 701 through a rotating shaft. The limiting collar 703 is arranged at the other end of the second telescopic rod 702. The upper parts of both the limiting collar 703 and the upper bolt 604 are of polygonal structures, so that the limiting collar 703 can be fitted and sleeved on the upper part of the upper bolt 604.

[0067] The first telescopic rod 701 and the second telescopic rod 702 can be made by coaxially sleeving two or more steel pipes in sequence to form a telescopic rod structure. After the upper bolt 604 is tightened and fixed, that is, after the electromechanical device 800 is clamped and fixed, the first telescopic rod 701 is vertically extended, and the second telescopic rod 702 is horizontally extended. The second telescopic rod 702 can be rotated until the limit collar 703 is located above the upper bolt 604, so that the limit collar 703 is sleeved into the upper part of the upper bolt 604 along with the vertical contraction of the first telescopic rod 701. Both the upper bolt 604 and the limit collar 703 can adopt a regular hexagon structure to ensure that the limit collar 703 can restrict the rotation of the upper bolt 604 after being sleeved into the upper part of the upper bolt 604, thereby improving the fastening reliability of the upper bolt 604, that is, the electromechanical device 800 can be reliably clamped. When unlocking is required, only need to move the limit collar 703 upward through the first telescopic rod 701 and separate it from the upper bolt 604, then the upper bolt 604 can be rotated and disassembled to release the clamping of the clamping plate 6011 on the electromechanical device 800.

[0068] Please refer to the appendix Figure 7 , the detection mechanism 500 includes a detection box 501, a floating object 503 and a shaking amplitude identification plate 504; the detection box 501 is arranged in the installation base 100, and the detection box 501 is filled with a water fluid 502 so that the floating object 503 can float in the detection box 501 through the water fluid 502; several shaking amplitude identification plates 504 are respectively arranged at intervals on the inner walls on both sides of the detection box 501, and several shaking amplitude identification plates 504 are arranged upward from the surface of the water fluid 502 to below the box opening of the detection box 501 in sequence.

[0069] Due to the vibration generated when the electromechanical device 800 operates, driving the installation base 100 and the detection mechanism 500 to vibrate synchronously, resulting in the vibration or shaking of the water fluid 502 in the detection box 501. The floating object 503 can be made of materials such as wood chips and plastic chips that can float on the water surface. When the floating object 503 floats with the water surface, it can be intercepted by the shaking amplitude identification plate 504. Thus, the shaking amplitude of the water fluid 502 can be judged according to the floating objects 503 on the shaking amplitude identification plates 504 at different heights. The size of the shaking amplitude of the water fluid 502 corresponds to the size of the vibration amplitude of the installation base 100, thereby visually judging the vibration condition of the installation base 100.

[0070] Please refer to the appendix Figure 9 and the appendix Figure 10The detection box 501 includes a transparent observation box 5011, a grade line column 5012 and a grade mark 5013; a plurality of grade line columns 5012 are respectively arranged at the corners of the transparent observation box 5011, and the grade mark 5013 is arranged between two adjacent grade line columns 5012; a plurality of grade marks 5013 are arranged at intervals between the surface of the water fluid 502 and the box opening of the detection box 501, and a plurality of shaking amplitude identification plates 504 are respectively arranged at the heights of the plurality of grade marks 5013.

[0071] The shaking amplitude of the mounting base 100 can be observed through the shaking of the water fluid 502 in the transparent observation box 5011. The grade mark 5013 can be marked with a red line on the transparent observation box 5011, which is convenient for installing the shaking amplitude identification plate 504. The observation is more intuitive and can be seen by people passing by, which is convenient for maintenance personnel to grasp the vibration situation in real time, avoiding the step of maintenance personnel carrying maintenance tools to inspect the mounting base 100 regularly, greatly improving work efficiency, and saving certain manpower and material costs.

[0072] The transparent observation box 5011 can be installed in the installation base 100 by a pull-out method to ensure installation stability, thereby ensuring the transmission of vibration force to the transparent observation box 5011, and also facilitating the removal of the transparent observation box 5011 and cleaning the floating objects 503 on the shaking amplitude identification plate 504.

[0073] Please see attached Figure 8 The shaking amplitude identification board 504 includes a folding frame 5041, a first magnetic strip 5042 and an elastic filter 5043; one end of the folding frame 5041 is fixedly set on the inner wall of the detection box 501, and the elastic filter 5043 is laid on the folding frame 5041; the first magnetic strip 5042 is set at the other end of the folding frame 5041 and is mutually repelled with the repulsion mechanism 900.

[0074] The folding frame 5041 can be made of plastic material, and adopts an X-shaped folding structure or other foldable forms. When the electromechanical device 800 is in operation, the folding frame 5041 can be folded and placed on the inner walls of both sides of the observation box 5011, so as to intercept the floating objects 503 at the maximum shaking amplitude of the water fluid 502 through the elastic filter 5043. The surface of the floating objects 503 can be made into a rough surface, so as to be easily intercepted by the elastic filter 5043. The elastic filter 5043 can be made of a material with a certain elastic deformation ability such as plastic to meet the laying and folding and stretching functions of the elastic filter 5043.

[0075] Please see attached Figure 12 and attached Figure 13, the repulsive mechanism 900 includes a limit slider 901, a ball 904, a connecting rod 905, a mounting plate 906 and a second magnetic strip 907; a first card slot 902 and a second card slot 903 are formed on the outer end surface of the limit slider 901, and the first card slot 902 and the second card slot 903 are vertically connected to form an L-shaped structure. The ball 904 is rotatably installed at the connection of the first card slot 902 and the second card slot 903; the connecting rod 905 can be fitted into the first card slot 902 or the second card slot 903, one end of the connecting rod 905 is connected to the ball 904, and the other end of the connecting rod 905 is connected to the mounting plate 906; a limit chute (not shown in the figure) is formed on the outer wall of the mounting base 100, and the inner end of the limit slider 901 and the mounting plate 906 are slidably installed in the limit chute; the second magnetic strip 907 is installed on the mounting plate 906, and the second magnetic strip 907 can be arranged repulsively outside the first magnetic strip 5042.

[0076] The first magnetic strip 5042 and the second magnetic strip 907 have opposite magnetic polarities. When the first magnetic strip 5042 and the second magnetic strip 907 approach each other, they can play a repulsive role. After the maintenance personnel detect and record the detection mechanism 500, the second magnetic strip 907 is inserted into the limit chute with the mounting plate 906, and the first magnetic strip 5042 is ejected by the magnetic force, so that the folding frame 5041 bounces and unfolds, thereby shaking off the floating objects 503 intercepted on the elastic filter screen 5043. The floating objects 503 can also be cleaned and shaken off manually. After the elastic filter screen 5043 is cleaned, the folding frame 5041 is folded, so that the first magnetic strip 5042 approaches the second magnetic strip 907 with the folding of the folding frame 5041, and the second magnetic strip 907 and the mounting plate 906 are ejected from the limit chute by the magnetic force, ensuring that the folding frame 5041 is folded and arranged at the side end of the detection box 5011.

[0077] The ball 904 can rotate in the first card slot 902 and the second card slot 903. The first card slot 902 and the second card slot 903 can be vertically arranged, and the shapes and sizes of the first card slot 902 and the second card slot 903 match the shapes and sizes of the connecting rod 905, so as to limit the connecting rod 905 and thus maintain the setting stability of the mounting plate 906.

[0078] Please refer to Appendix Figure 1 to Appendix Figure 13 , a shaking detection method for a building mechanical and electrical installation base with a shaking detection function, including the following steps:

[0079] Step 1: Fix the mechanical and electrical equipment 800 on the top of the mounting base 100 through several groups of clamping mechanisms 600, and fix the mounting base 100 through the lower bolts 300.

[0080] The said Step 1 includes the following sub-steps:

[0081] Step 1.1: Place the bottom of the electromechanical device 800 in the placement groove 400 of the mounting base 100. The bottom of the electromechanical device 800 is restricted by the placement groove 400 to prevent the electromechanical device 800 from slipping and falling on the mounting base 100.

[0082] Step 1.2: Screw the upper bolt 604 into the threaded groove 602 and drive the pressing slider 605 to slide downward along the vertical section of the sliding groove 603, so that the pressing slider 605 presses the deformable airbag 6012. The length of the upper bolt 604 can be determined according to the pressing stroke of the deformable airbag 6012.

[0083] Step 1.3: The deformable airbag 6012 pushes the pressing slider 607 outward and makes the clamping plate 6011 tightly fit on the electromechanical device 800.

[0084] At this time, the limit block 608 slides synchronously with the pressing slider 607 along the limit groove 609, and the compression spring 6010 is stretched, which is convenient for using the elasticity of the compression spring 6010 to squeeze the deformable airbag 6012 to restore its original shape when disassembling the electromechanical device 800, achieving the purpose of resetting.

[0085] Step 2: Sleeve the anti-loosening mechanism 700 on the clamping mechanism 600 to limit the clamping mechanism 600.

[0086] The said Step 2 includes the following sub-steps:

[0087] Step 2.1: Stretch the first telescopic rod 701 upward and rotate the second telescopic rod 702 around the first telescopic rod 701.

[0088] Preferably, the lengths of the first telescopic rod 701 and the second telescopic rod 702 can be determined according to the actual installation requirements, and the first telescopic rod 701 and the second telescopic rod 702 are vertically arranged.

[0089] Step 2.2: Stretch the second telescopic rod 702 to one side so that the limit collar 703 is located above the upper bolt 604.

[0090] Step 2.3: Shrink the first telescopic rod 701 downward so that the limit collar 703 is fitted and sleeved on the upper part of the upper bolt 604, and the limit collar 703 is relatively fixed to the upper bolt 604.

[0091] Step 3: When the electromechanical device 800 is running, detect the shaking condition of the mounting base 100 through the detection mechanism 500.

[0092] The said Step 3 includes the following sub-steps:

[0093] Step 3.1: The electromechanical device 800 generates vibrations during operation and makes the detection box 501 vibrate synchronously with the mounting base 100.

[0094] Step 3.2: The water fluid 502 sways under the action of vibration, driving the floating object 502 to sway synchronously with the water surface. When the floating object 503 sways, it spreads upward along the side wall of the detection box 501 and leaves part of the floating object 502 on the sway amplitude identification board 504.

[0095] Step 3.3: The operator observes the vibration state of the water fluid 502 through the transparent observation box 5011, and at the same time judges the vibration intensity of the water fluid 502 by the floating objects 502 intercepted on the elastic filter screen 5043 at the height of different grade marks 5013.

[0096] The stronger the vibration of the mounting base 100, the stronger the sway of the water fluid 502, and the higher the upward spread height of the water fluid 502 along the detection box 501. Thus, the floating object 503 is intercepted on the sway amplitude identification board 504 at the highest spread height, which is used to mark the sway intensity of the water fluid 502, that is, the vibration amplitude of the mounting base 100.

[0097] The maintenance personnel judge which components need to be replaced and carry out targeted reinforcement by the maintenance duration, maintenance equipment, and the vibration amplitude detected by the detection mechanism 500, reducing the maintenance work of the electromechanical equipment 800 caused by vibration and gradually extending the maintenance cycle.

[0098] Step 4: During maintenance, the detection mechanism 500 is repelled by the repulsion mechanism 900 to reset the detection mechanism 500.

[0099] The said Step 4 includes the following sub-steps:

[0100] Step 4.1: Rotate the mounting plate 906 through the connecting rod 905 via the ball 904 to be parallel to the first slot 902, and embed the connecting rod 905 into the first slot 902.

[0101] Preferably, the ball 904 can be installed by using a ball bearing or the like to ensure the installation and rolling of the ball 904.

[0102] Step 4.2: Slide the limit slider 901 along the limit chute, so that the limit slider 901, the mounting plate 906, and the second magnetic strip 907 are embedded into the limit chute.

[0103] Slots can be formed on the mounting plate 906 to form a concave structure, which is convenient for installing the second magnetic strip 907 and also convenient for the second magnetic strip 907 to be closer to the first magnetic strip 5042 to ensure the effectiveness of the repulsive force.

[0104] Step 4.3: The second magnetic strip 407 approaches the first magnetic strip 5042 along with the mounting plate 906 and generates a repulsive force on the first magnetic strip 5042, causing the folding frame 5041 to unfold.

[0105] Step 4.4: Clean the floating matter 503 on the elastic filter screen 5043 and fold the folding frame 5041.

[0106] Step 4.5: As the folding frame 5041 folds, the first magnetic strip 5042 approaches the second magnetic strip 907, generating a repulsive force on the second magnetic strip 907, causing the mounting plate 906 and the second magnetic strip 907 to pop out from the limiting chute.

[0107] Step 4.6: Rotate the mounting plate 906 through the connecting rod 905 via the ball 904 to be parallel to the second card slot 903, and insert the connecting rod 905 into the second card slot 903.

[0108] The mounting plate 906 is located outside the limiting chute, which can prevent the second magnetic adjustment 907 from generating a repulsive force on the first magnetic strip 5042, thus ensuring that the shaking amplitude identification plate 504 is folded and arranged on the inner side wall of the detection box 501.

[0109] The usage method of the present invention is as follows:

[0110] The upper bolt 604 drives the pressing slider 605 to move downward under the action of the thread groove 602, causing the pressing slider 605 to continuously squeeze the deformation airbag 6012, making the deformation airbag 6012 expand towards the side of the electromechanical device 800, thereby pushing the pressing slider 607 and the clamping plate 6011 to move towards the electromechanical device 800. At the same time, the compression spring 6010 undergoes an extended deformation under the traction force of the pressing slider 607, clamping and fixing the electromechanical device 800 on the top of the mounting base 100.

[0111] Subsequently, after both sets of clamping mechanisms 600 clamp and fix the electromechanical device 800, pull the first telescopic rod 701 upward, so that the overall height of the first telescopic rod 702 rises until it is higher than the upper bolt 604. Then, pull the second telescopic rod 702 towards the clamping mechanism 600, causing the second telescopic rod 702 to be located above the upper bolt 604 at this time. Then, press the first telescopic rod 701 again, causing the limiting collar 703 to be sleeved on the outer surface of the upper bolt 604, locking and limiting the clamping mechanism 600 to prevent the clamping mechanism 600 from loosening due to vibration during the operation of the electromechanical device 800. When it is necessary to replace, move or repair the electromechanical device 800, the staff can release the limit of the upper bolt 604 by the anti-loosening mechanism 700, and then rotate the upper bolt 604 counterclockwise, causing the upper bolt 604 to drive the pressing slider 605 to move upward. At the same time, the deformation airbag 6012 gradually starts to reset under the action of no extrusion force, no longer pressing the pressing slider 607 and the clamping plate 6011. Driven by the reset characteristic of the compression spring 6010, the clamping plate 6011 is driven to reset again, no longer continuing to clamp and fix the electromechanical device 800, and then the electromechanical device 800 is disassembled.

[0112] When the mounting base 100 shakes due to the loosening of multiple connecting bolts caused by the vibration generated during the long-term operation of the electromechanical device 800, the water fluid 502 inside the detection box 501 floats and spreads on the inner wall of the detection box 501 due to the shaking. Moreover, the greater the shaking force of the mounting base 100, the greater the floating amplitude of the water fluid 502 in the detection box 501, causing the floating objects 503 attached to the surface of the water fluid 502 to touch the surface of the shaking amplitude identification plate 504.

[0113] During daily work, the staff can observe through the detection box 501 which layer the floating objects 503 on the surface of the multi-layer shaking amplitude identification plate 504 are located. The floating objects 503 attached to the surface of the shaking amplitude identification plate 504 farther away from the water fluid indicate that the upper bolt 604 and the lower bolt 300 may be more loose at this time, which can remind the maintenance personnel to carry tools for maintenance. Subsequently, when the maintenance personnel perform maintenance, they can make the folding frame 5041 of the shaking amplitude identification plate 504 bounce and unfold by operating the approach and separation of the second magnetic strip 907 of the repulsive force mechanism 900 to generate a repulsive force with the first magnetic strip 5042, causing the floating objects 503 attached to the surface of the shaking elastic filter screen 5043 to shake and fall onto the surface of the water fluid 502, facilitating continued shaking detection in the later stage and enhancing the safety of the electromechanical device 800 during use.

[0114] After the detection is completed and the detection mechanism 500 is reset, the electromechanical device 800 can be started, and it is observed whether the water fluid 502 does not shake or only shakes slightly. If so, the electromechanical device 800 can be operated normally. If not, continue to check and maintain the tightness of the upper bolt 604 and the lower bolt 300 until the water fluid 502 can remain stable.

[0115] The above is only the preferred embodiment of the present invention and is not used to limit the protection scope of the invention. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
