After the mounting plate descends, the electromagnet absorbs the liquid magnet in the liquid storage tube, and the liquid magnet covers the trigger switch and triggers the trigger switch. When the trigger switch is turned on, the monitoring controller runs and receives an output value of the sliding rheostat that is different from the output value of the reference point, and the sinking situation is obtained. According to the principle of the sliding rheostat, when other conditions are the same, the size of the resistance is proportional to the length of the resistance wire. Then, the sliding distance of the slider on the sliding rheostat is calculated, and then the distance that the building has dropped relative to the reference point when the building sinks but the monitoring point has not sunk is obtained, which is convenient for settlement measurement and improves the measurement effect and measurement accuracy.

If the foundation monitoring point settles, the connecting rod 17 descends to drive the graphite connecting block 18 to descend, because the graphite connecting block 18 is connected to the building and will directly The graphite connecting block 18 is torn off. At this time, for uneven sinking, part of the building has not moved. The breakage of the graphite connecting block 18 indicates that the building has not moved or the sinking of the building is different from the sinking of the settlement monitoring mechanism 1, and the settlement is uneven. If the building and the foundation sink together, the graphite connecting block 18 will not break. If the building sinks, the ratchet bar 165 can slide downward on the block 163 so that the graphite connecting block 18 will not be torn off. When it needs to be reset, pull the slide bar 162 to drive the block 163 to separate from the ratchet bar 165, and replace it with a new graphite connecting block 18 as appropriate, and connect the building and the connecting rod 17 through the graphite connecting block 18.

The outer side of the limit strip 142 is slidably connected with the inner wall of the adjustment groove. The inner side of the top of the adjustment sleeve 141 is threadedly connected with the adjustment screw 143. The top of the left end of the liquid storage tube 13 is threadedly connected with the fixed screw 144. The motion trajectory is linear, the motion trajectory of the limit bar 142 is linear, and the motion trajectory of the fixed screw 144 intersects with the motion trajectory of the limit bar 142. When the settlement monitoring mechanism 1 is installed, the limit bar 142 can be rotated in the adjusting sleeve 141 as needed to drive the sliding rheostat 151 to move up and down, or the adjusting sleeve 141 can be pulled and then the fixed screw 144 can be tightened to fit with the limit bar 142 to fix the position of the adjusting sleeve 141, and the initial position of the sliding rheostat 151 can be adjusted to facilitate fine-tuning according to actual conditions and facilitate settlement monitoring operations.

[0025] The limiting assembly 16 includes a slide 161, a slide bar 162, a block 163, a spring 164 and a ratchet bar 165.

A connecting groove is provided inside the slide 161, and the ratchet bar 165 is slidably connected to the inner side wall of the connecting groove. An elastic groove is provided inside the slide 161, and the block 163 is slidably connected to the inner side wall of the elastic groove. The right end of the block 163 is fixedly connected to the slide bar 162, and the slide bar 162 passes through the surface of the slide 161. The right end of the block 163 is fixedly connected to the spring 164. The spring 164 is arranged at the circumferential position of the slide bar 162, and the distance that the liquid storage tube 13 descends after the sinking occurs is obtained. At the same time, when the liquid storage tube 13 descends, because the spring 164 in the slide seat 161 pushes the clamping block 163 to engage with the ratchet bar 165, the liquid storage tube 13 moves downward, and the liquid storage tube 13 drives the ratchet bar 165 to move downward through the spring 164, and the ratchet bar 165 drives the connecting rod 17 downward to move downward, and the descent of the connecting rod 17 drives the graphite connecting block 18 to descend, because the graphite connecting block 18 is connected to the building, which will directly tear the graphite connecting block 18 off.

[0026] The measuring assembly 15 includes a sliding rheostat 151, a slider 152, a synchronization rod 153, a mounting plate 154, an airbag 155 and a floating block 156. The bottom end of the adjusting screw 143 is rotatably connected to the sliding rheostat 151 through a rotating shaft, the slider 152 is slidably connected to the outer side of the sliding rheostat 151, the bottom end of the slider 152 is fixedly connected to the synchronization rod 153, the bottom end of the synchronization rod 153 is fixedly connected to the mounting plate 154, the bottom end of the mounting plate 154 is fixedly connected to the airbag 155, the bottom end of the mounting plate 154 is fixedly connected to the floating block 156, and the liquid storage tube 13 enters the flowing medium, which is generally an inert liquid. When the lower part of the monitoring controller 11 sinks, the monitoring controller 11 is lowered, and the liquid storage tube 13 descends. In order to keep the liquid level consistent, the liquid level in the liquid storage tube 13 rises relatively. The air in the airbag 155 provides buoyancy to make the mounting plate 154 rise relatively. The rise of the mounting plate 154 drives the slider 152 to slide and rise on the sliding rheostat 151. The output of the sliding rheostat 151 received by the monitoring controller 11 is different from the output value of the reference point, and the sinking is obtained. According to the principle of the sliding rheostat, when other conditions are the same, the size of the resistance is proportional to the length of the resistance wire, and then the sliding distance of the slider 152 on the sliding rheostat 151 is calculated, and then the descending distance of the liquid storage tube 13 after the sinking occurs is obtained.

[0027] A connecting hole is provided at the top of the liquid storage tube 13, and a ratchet bar 165 is arranged on the inner side of the connecting hole. A connecting rod 17 is fixedly connected to the top of the ratchet bar 165, and a graphite connecting block 18 is fixedly connected to the right end of the connecting rod 17. The right end of the graphite connecting block 18 is fixedly connected to the building wall. The graphite connecting block 18 is driven down by the descending of the connecting rod 17, because the graphite connecting block 18 is connected to the building and the graphite connecting block 18 will be directly torn off. At this time, for uneven sinking, part of the building has not moved, and the breakage of the graphite connecting block 18 indicates that the building has not moved or the sinking of the building is different from the sinking of the settlement monitoring mechanism 1, and the settlement is uneven.

[0028] Working principle: When the device is in use, the monitoring controller 11 mainly controls the device, the external pipe 12 is connected to the water pipe of the reference point bucket, and the flowing medium enters the liquid storage tube 13, which is generally an inert liquid. When the part below the monitoring controller 11 sinks, the monitoring controller 11 is lowered, and the liquid storage tube 13 drops. In order to keep the liquid level consistent, the liquid level in the liquid storage tube 13 rises relatively, and the air in the airbag 155 provides buoyancy to make the mounting plate 154 rise relatively. The rise of the mounting plate 154 drives the slider 152 to slide and rise on the sliding rheostat 151. The output of the sliding rheostat 151 received by the monitoring controller 11 is different from the output value of the reference point, and the sinking situation is obtained. According to the principle of the sliding rheostat, when other conditions are the same, the size of the resistance is proportional to the length of the resistance wire, and then the sliding distance of the slider 152 on the sliding rheostat 151 is calculated, and then the descending distance of the liquid storage tube 13 after the sinking occurs is obtained. At the same time, when the liquid storage tube 13 descends, because the elastic force in the slide seat 161 The spring 164 pushes the card block 163 to engage with the ratchet bar 165, and the liquid storage tube 13 moves downward. The liquid storage tube 13 drives the ratchet bar 165 to move downward through the spring 164, and the ratchet bar 165 drives the connecting rod 17 to move downward. The connection rod 17 descends and drives the graphite connecting block 18 to descend. Because the graphite connecting block 18 is connected to the building, the graphite connecting block 18 will be directly torn off. At this time, for uneven sinking, the building part does not move, and the graphite connecting block 18 is broken, which means that the building has not moved or the building has not moved. The sinking of objects is different from the sinking of the settlement monitoring mechanism 1, and the settlement is uneven. If the building and the foundation sink together, the graphite connecting block 18 will not break. If the building sinks, the ratchet bar 165 can slide downward on the block 163 so that the graphite connecting block 18 will not be torn off. When it needs to be reset, pull the slide bar 162 to drive the block 163 to separate from the ratchet bar 165, and replace it with a new graphite connecting block 18 as appropriate, and connect the building and the connecting rod 17 through the graphite connecting block 18.

[0029] It should be understood that: the initial position of the slider 152 is the zero point, the value above the initial position of the slider 152 is a positive value, and the value below the initial position of the slider 152 is a negative value, the value of sinking is a positive number, and the value of rising is a negative number, and the obtained distance is the absolute value of the above value.

When the device is in use, the monitoring controller 11 mainly controls the device, the external pipe 12 is closed, and a flowing medium is added to the liquid storage pipe 13, which is generally a liquid magnet. When the building sinks, the connecting rod 17 also sinks. , the liquid storage tube 13 does not move, the building wall drives the ratchet bar 165 downward through the connecting rod 17, and after the mounting plate 154 descends, the electromagnet 157 absorbs the liquid magnet in the liquid storage tube 13, and the liquid magnet covers the trigger switch 158 and triggers the trigger switch 158. When the trigger switch 158 is turned on, the monitoring controller 11 runs and receives the output of the sliding rheostat 151 which is different from the output value of the reference point, and obtains the sinking situation. According to the principle of the sliding rheostat, when other conditions are the same, the size of the resistance is proportional to the length of the resistance wire, and then calculates the sliding distance of the slider 152 on the sliding rheostat 151, and then obtains the distance that the building has dropped relative to the reference point when the building sinks but the monitoring point has not sunk.

When the building sinks and the connecting rod 17 also sinks, the liquid storage tube 13 does not move, and the wall of the building drives the ratchet bar 165 downward through the connecting rod 17. The meshing design of the ratchet bar 165 and the block 163 enables the connecting rod 17 to drive the ratchet bar 165 to move downward, and the ratchet bar 165 drives the mounting plate 154 downward.

[0033] The measuring assembly 15 includes a sliding rheostat 151, a slider 152, a synchronization rod 153, a mounting plate 154, an electromagnet 157 and a trigger switch 158.

[0035] Working principle: When the device is in use, the monitoring controller 11 controls the device, the external pipe 12 is closed, and a flowing medium is added to the liquid storage tube 13, which is generally a liquid magnet. When the building sinks and the connecting rod 17 sinks, the liquid storage tube 13 does not move, and the wall of the building drives the ratchet bar 165 downward through the connecting rod 17.

When the trigger switch 158 is turned on, the monitoring controller 11 will run and receive the output of the sliding rheostat 151 which is different from the output value of the reference point, and the sinking situation will be obtained. According to the principle of the sliding rheostat, when other conditions are the same, the size of the resistance is proportional to the length of the resistance wire. Then the distance that the slider 152 slides on the sliding rheostat 151 is calculated, and then the distance that the building drops relative to the reference point when the building sinks but the monitoring point does not sink. When resetting is required, pull the slide bar 162 to drive the block 163 to separate from the ratchet bar 165.

[0036] It should be noted that: in combination with the above: it is necessary to equip multiple devices of Example 1 and Example 2 at the same monitoring point, that is, to use them at the same time to monitor the foundation settlement and building settlement at the same time.
