After detecting and recording the detecting mechanism 500, the maintenance personnel embeds the second magnetic stripe 907 into the limiting chute along with the mounting plate 906, and ejects the first magnetic stripe 5042 by utilizing magnetic force, so that the folding frame 5041 is sprung and unfolded, and thus floats 503 trapped on the elastic filter screen 5043 are shaken off.

Referring to fig. 1 to 13, a shake detection method for a building electromechanical installation base with shake detection function includes the following steps:

step 1: the electro-mechanical device 800 is fixed to the top of the mounting base 100 by several sets of clamping mechanisms 600 and the mounting base 100 is fixed by the lower bolts 300.

The step 1 comprises the following sub-steps:

step 1.1: the bottom of the electro-mechanical device 800 is placed in the placement groove 400 of the mounting base 100. The bottom of the electro-mechanical device 800 is restrained by the placement groove 400, preventing the electro-mechanical device 800 from slipping and falling on the mounting base 100.

Step 1.2: the upper bolt 604 is screwed into the thread groove 602 and drives the pressing slider 605 to slide downwards along the vertical section of the chute 603, so that the pressing slider 605 presses the deformation air bag 6012 downwards, and the length of the upper bolt 604 can be determined according to the pressing stroke of the deformation air bag 6012.

Step 1.3: the deformation air bag 6012 pushes the pressing slider 607 outwards, and presses the clamping plate 6011 against the electromechanical apparatus 800.

At this time, the limiting block 608 slides along the limiting groove 609 along with the pressing sliding block 607 synchronously, and the compression spring 6010 is stretched, so that the deformation air bag 6012 is elastically extruded by the compression spring 6010 to restore the original shape when the electromechanical device 800 is disassembled, and the purpose of restoring is achieved.

Step 2: the anti-loosening mechanism 700 is sleeved on the clamping mechanism 600, and the clamping mechanism 600 is limited.

The step 2 comprises the following sub-steps:

step 2.1: the first telescoping rod 701 is elongated upward and the second telescoping rod 702 is rotated about the first telescoping rod 701.

Preferably, the lengths of the first and second telescopic links 701 and 702 may be determined according to actual installation requirements, and the first and second telescopic links 701 and 702 are vertically disposed.

Step 2.2: the second telescoping rod 702 is extended to one side with the stop collar 703 above the upper bolt 604.

Step 2.3: the first telescopic rod 701 is contracted downwards, so that the limiting lantern ring 703 is matched and sleeved on the upper part of the upper bolt 604, and the limiting lantern ring 703 and the upper bolt 604 are relatively fixed.

Step 3: when the electromechanical device 800 is operated, the shaking condition of the mounting base 100 is detected by the detecting mechanism 500.

The step 3 comprises the following sub-steps:

step 3.1: the electromechanical device 800 produces vibration during operation and causes the detection chamber 501 to vibrate in synchronization with the mounting base 100.

Step 3.2: the water fluid 502 shakes under the vibration action and drives the floaters 502 to shake synchronously with the water surface, and the floaters 503 creep upwards along the side wall of the detection box 501 and leave part of the floaters 502 on the shake amplitude identification plate 504 when shaking.

Step 3.3: an operator observes the vibration state of the water fluid 502 through the transparent observation box 5011, and simultaneously judges the vibration intensity of the water fluid 502 through the floats 502 trapped on the elastic filter screens 5043 at the heights of the different grade marks 5013.

The stronger the vibration of the installation base 100, the stronger the shaking of the water fluid 502, and the higher the upward spreading height of the water fluid 502 along the detection box 501, so that the floats 503 are trapped on the shaking amplitude recognition plate 504 at the highest spreading height, for marking the shaking intensity of the water fluid 502, that is, the shaking amplitude of the installation base 100.

Maintenance personnel judge which parts need to be replaced and are reinforced in a targeted mode through the maintenance time length, the maintenance equipment and the detection range of shaking through the detection mechanism 500, so that maintenance work of the electromechanical device 800 caused by shaking is reduced, and the maintenance period is gradually prolonged.

Step 4: during maintenance, the detection mechanism 500 is reset by the repulsive force mechanism 900 repulsive the detection mechanism 500.

The step 4 comprises the following sub-steps:

step 4.1: the mounting plate 906 is rotated by the link 905 to be parallel to the first catching groove 902 through the balls 904, and the link 905 is fitted into the first catching groove 902.

Preferably, the balls 904 may be embedded with ball bearings or the like to ensure the mounting and rolling of the balls 904.

Step 4.2: the limit slide 901 slides along the limit slide groove, so that the limit slide 901, the mounting plate 906 and the second magnetic stripe 907 are embedded into the limit slide groove.

The mounting plate 906 may be formed with a slot to form a concave structure to facilitate mounting of the second magnetic stripe 907 and to facilitate the second magnetic stripe 907 to be closer to the first magnetic stripe 5042 to ensure effectiveness of the repulsive force.

Step 4.3: the second magnetic stripe 407 approaches the first magnetic stripe 5042 with the mounting plate 906 and generates a repulsive force against the first magnetic stripe 5042, causing the folding frame 5041 to unfold.

Step 4.4: the floats 503 on the shake-off elastic screen 5043 are cleaned and the folding frame 5041 is folded.

Step 4.5: the first magnetic stripe 5042 approaches the second magnetic stripe 907 along with the folding of the folding frame 5041, and generates a repulsive force to the second magnetic stripe 907, so that the mounting plate 906 and the second magnetic stripe 907 are ejected from the limit chute.

Step 4.6: the mounting plate 906 is rotated to be parallel to the second catching groove 903 through the balls 904 by the link 905, and the link 905 is fitted into the second catching groove 903.

The mounting plate 906 is located outside the limiting chute, and can prevent the second magnetic tone 907 from generating a repulsive force to the first magnetic stripe 5042, thereby ensuring that the shaking amplitude identification plate 504 is folded and arranged on the inner side wall of the detection box 501.

The application method of the invention is as follows:

the upper bolt 604 drives the pressing slider 605 to move downwards under the action of the thread groove 602, so that the pressing slider 605 continuously extrudes the deformation air bag 6012, and the deformation air bag 6012 expands towards one side of the electromechanical device 800, thereby pushing the pressing slider 607 and the clamping plate 6011 to move towards the electromechanical device 800, and simultaneously, the compression spring 6010 is stretched and deformed under the traction force of the pressing slider 607, so that the electromechanical device 800 is clamped and fixed at the top of the mounting base 100.

Then, after the two groups of clamping mechanisms 600 are used for fixedly clamping the electromechanical device 800, the first telescopic rod 701 is pulled upwards, so that the overall height of the first telescopic rod 702 is increased until the first telescopic rod is higher than that of the upper bolt 604, then the second telescopic rod 702 is pulled towards one side of the clamping mechanism 600, so that the second telescopic rod 702 is positioned above the upper bolt 604, then the first telescopic rod 701 is pressed again, the limiting collar 703 is sleeved on the outer surface of the upper bolt 604, the clamping mechanism 600 is locked and limited, and the phenomenon that the clamping mechanism 600 loosens due to vibration in the operation process of the electromechanical device 800 is prevented. When the electromechanical device 800 needs to be replaced, moved or maintained, a worker can remove the limit of the anti-loosening mechanism 700 on the upper bolt 604, then rotate the upper bolt 604 counterclockwise, so that the upper bolt 604 drives the pressing sliding block 605 to move upwards, and meanwhile, the deformation air bag 6012 gradually begins to reset under the action of no pressing force, does not press the pressing sliding block 607 and the clamping plate 6011, drives the clamping plate 6011 to reset again under the reset characteristic of the compression spring 6010, does not continuously clamp and fix the electromechanical device 800, and then disassembles the electromechanical device 800.

When the installation base 100 shakes due to loosening of a plurality of connected bolts caused by vibration generated when the electromechanical device 800 operates for a long time, the water fluid 502 in the detection box 501 floats and spreads on the inner wall of the detection box 501 due to the shaking, and when the shaking force of the installation base 100 is larger, the floating amplitude of the water fluid 502 in the detection box 501 is larger, so that a floater 503 attached to the surface of the water fluid 502 touches the surface of the shaking amplitude identification plate 504.

In daily work, staff can observe through the detection box 501 which layer the floater 503 on the surface of the multi-layer shaking amplitude identification plate 504 is located on, and the floater 503 is attached to the surface of the shaking amplitude identification plate 504 far away from the water fluid, so that the upper bolt 604 and the lower bolt 300 are possibly loose, maintenance staff can be reminded of carrying tools for maintenance treatment, then when the maintenance staff maintains, the maintenance staff can operate the second magnetic stripe 907 of the repulsive force mechanism 900 to approach and keep away from the first magnetic stripe 5042 to generate repulsive force, so that the folding frame 5041 of the shaking amplitude identification plate 504 is sprung and unfolded, the floater 503 attached to the surface of the shaking elastic filter screen 5043 is shaken and falls onto the surface of the water fluid 502, the later period of shaking detection is facilitated, and the safety of the electromechanical equipment 800 in the use process is enhanced.

After the detection is completed and the detection mechanism 500 is reset, the electromechanical device 800 can be started to observe whether the water fluid 502 does not shake or shakes only slightly, if so, the electromechanical device 800 can be normally operated, and if not, the tightness of the upper bolt 604 and the lower bolt 300 can be continuously checked and maintained until the water fluid 502 can be kept stable.

The foregoing description of the preferred embodiments of the invention is not intended to limit the scope of the invention, and therefore, any modifications, equivalents, improvements, etc. that fall within the spirit and principles of the invention are intended to be included within the scope of the invention.
