[0004] When a house sinks, there is a high probability that the area near the house will also sink. In practical applications, this situation will have a significant impact on the measurement accuracy of the house settlement measuring device. Existing monitoring devices usually measure the settlement of the house based on a relatively fixed reference point. If the area near the house also sinks, the reference point that was originally considered to be stable will no longer be so stable and will move with the surrounding area, causing deviations in the measurement results and making the measurement results inaccurate.

[0022] 3. When the fixed trough plate sinks, the tension rope will be pulled by the pull rope fixing block, and the tension rope will be pulled. The tension sensor receives a stronger tension induction.

[0023] 4. The house foundation settlement monitoring device allows the water entering the fall well to be discharged into deeper soil through the water drainage pipe at the bottom of the fall well, so that the soil at the bottom of the fixed groove plate remains relatively dry, which can further prevent the fixed groove plate from settling. When the fixed groove plate settles and the servo motor drives the spiral plate to lift the fixed groove plate, the water drainage pipe drains the water into deeper soil, which can make the spiral plate push the fixed groove plate upward more stably, better prevent the fixed groove plate from settling, and ensure that the measured data is more accurate.

[0037] Example 1: Please refer to Figure 1-9 The present invention provides a technical solution: a house foundation settlement monitoring device, comprising a fixed groove plate 1, which is fixed on the ground slightly away from the wall surface, so that the device can avoid being affected by the foundation settlement, and avoiding the effect of house settlement will make the measured data more accurate. A measuring component 2 is fixedly connected to the top of the fixed groove plate 1, and an anti-sinking mechanism 3 is fixedly connected to the bottom of the fixed groove plate 1;

[0038] The measurement component 2 includes:

[0039] A main bearing fixing block 201, which is fixedly connected to the top of the fixed slot plate 1;

[0040] A horizontal movable rod 202, the horizontal movable rod 202 is fixedly connected to the outer wall of the main bearing fixed block 201;

[0041] The guide sliding sleeve 203 is movably connected to the outer wall of the horizontal movable rod 202.

[0042] Two main bearing fixed blocks 201 are provided, and two ends of the horizontal movable rod 202 are respectively fixedly connected to different main bearing fixed blocks 201 , and the outer wall of the guide sliding sleeve 203 is movably connected to two length measuring belts 204 .

[0043] A movable connecting rod 206 is movably connected to the top of the length measuring belt 204, and a wall mounting plate 205 is movably connected to the outer wall of the movable connecting rod 206. The wall mounting plate 205 is fixedly connected to the outer wall of the building. An angle observation disk 207 is fixedly connected to the outer side of the main bearing fixing block 201. A reading scale 215 is arranged on the right side of the length measuring belt 204, and both ends of the reading scale 215 are respectively fixedly connected to the two main bearing fixing blocks 201.

[0044] A drop well 212 is fixedly connected to the bottom of the fixed trough plate 1, and a second drop cone block 211 is fixedly connected to the bottom of the length measuring tape 204. The second drop cone block 211 is made of solid and dense metal, and the bottom of the second drop cone block 211 is conical to make the second drop cone block 211 more stable. The second drop cone block 211 pulls the corresponding length measuring tape 204 downward to keep the length measuring tape 204 straight, so that the length measurement is more accurate and the overall accuracy is improved. A water drainage pipe 213 is fixedly connected to the bottom of the drop well 212, and drainage holes 214 are provided on the outer wall of the water drainage pipe 213. The drop well 212 will discharge the incoming rainwater into the soil through the drainage holes 214 on the water drainage pipe 213 to avoid interference with the equipment.

[0045] The outer wall of the guide sliding sleeve 203 is movably connected with a first falling cone block 208, which is made of solid metal with high density, and the bottom of the first falling cone block 208 is conical to make the first falling cone block 208 more stable. A scale indicator header 209 is fixedly connected to the left side of the first falling cone block 208, and a movable scale ruler 210 is arranged at the bottom of the scale indicator header 209, and the two ends of the movable scale ruler 210 are respectively fixedly connected to the corresponding main bearing fixed block 201. When the house moves horizontally, Since the second falling cone block 211 will be pulled downward by the guide sliding sleeve 203, the guide sliding sleeve 203 can move laterally on the horizontal movable rod 202, and the forces act on the guide sliding sleeve 203 together. The combined force will cause the guide sliding sleeve 203 to move in the direction of the house offset. The guide sliding sleeve 203 will move with the first falling cone block 208 when moving. The first falling cone block 208 is heavier, and the first falling cone block 208 will maintain the position of the scale indicator head 209 relative to the moving scale ruler 210 under the action of gravity.

[0046] The outer wall of the angle observation disk 207 is provided with angle markings, and the reading is taken at the position where the two length measuring tapes 204 overlap. The degree read is the angle between the length measuring tape 204 and the horizontal ground at this time. The outer wall of the length measuring tape 204 is provided with length markings. The scale on the length measuring tape 204 is observed by the reading ruler 215, and the reading obtained is the distance from the guide sliding sleeve 203 to the wall mounting plate 205 at this time. The outer wall of the movable scale ruler 210 is provided with length markings. By observing the position indicated by the scale indicating head 209 on the movable scale ruler 210, the reading is recorded, and then the position indicated by the scale indicating head 209 on the movable scale ruler 210 is observed again. The reading is recorded and compared with the previous reading to obtain the value of the front-to-back direction offset of the house.

[0047] When in use, the wall mounting plate 205 is fixedly connected to the outer wall of the building, and the fixed groove plate 1 is fixed to the ground slightly away from the wall, so that the fixed groove plate 1 is in contact with the ground, and the rest is at the bottom of the ground. After the device is installed, the second falling cone block 211 pulls the corresponding length measuring tape 204 downward to keep the length measuring tape 204 in a straight state, so that the length measurement is more accurate and the overall accuracy is improved. The scale on the length measuring tape 204 is observed through the reading ruler 215, and the length at this time is recorded. The length is recorded as a, and then the angle observation disk 207 is observed, and the reading is taken at the position where the two length measuring tapes 204 overlap. The read angle is recorded as α, and the position indicated by the scale indicator header 209 on the moving scale ruler 210 is observed to record the reading. In the process of the house moving up and down The distance between the movable connecting rod 206 and the guide sliding sleeve 203 will be changed, and the second falling cone block 211 will move downward in the falling well 212 with the length measuring tape 204. The falling well 212 will allow the rainwater that falls in to be discharged into the soil through the drainage holes 214 on the water drainage pipe 213 to avoid interference with the equipment. When the house moves laterally, since the second falling cone block 211 will be pulled downward by the guide sliding sleeve 203, the guide sliding sleeve 203 can move laterally on the horizontal movable rod 202, and the forces will act on the guide sliding sleeve 203 together. The combined force will cause the guide sliding sleeve 203 to move in the direction of the house offset. The guide sliding sleeve 203 will move with the first falling cone block 208 when moving. The first falling cone block 208 is heavier and keeps the position of the scale indicator header 209 relative to the moving scale ruler 210.

[0048] Observe again after a period of time, observe the scale on the length measuring tape 204 through the reading ruler 215, and record the length at this time, which is recorded as b, then observe the angle observation disk 207, and read the angle at the overlapping position of the two length measuring tapes 204, and record the read angle as θ. At this time, the left and right offsets of the house are calculated to be asinα-bsinθ, and the positive and negative numbers of the obtained values ​​represent the left and right values ​​respectively, which are the offset distances. The up and down offsets of the house are calculated to be acosα-bcosθ, and the positive and negative numbers of the obtained values ​​represent the downward and upper right values ​​respectively, which are the settlement distances. Observe the position indicated by the scale indicator head 209 on the moving scale ruler 210 at this time, and record By recording the readings and comparing them with the last readings, the value of the front-to-back displacement of the house can be obtained. The three displacement values ​​can be used to comprehensively judge the displacement data of the house. Analyzing the settlement of a house by the moving distance of a point on the side of the house in three directions has many advantages. On the one hand, it can comprehensively evaluate the settlement status of the house. The horizontal moving distance can reflect whether the house has an overall horizontal displacement and the possible reasons. The vertical moving distance is a direct indicator for evaluating the degree and trend of house settlement. On the other hand, it helps to assist in judging the type of settlement. According to the changes in the moving distances in the three directions and their mutual relationship, it can be judged whether it is uniform settlement or uneven settlement, so as to detect problems in time.

[0049] Example 2: Please refer to Figure 1-10 Based on the first embodiment, the present invention provides a technical solution:

[0050] The anti-sinking mechanism 3 comprises a servo motor 301 . The servo motor 301 is fixedly connected inside the fixed slot plate 1 . A spiral plate 302 is fixedly connected to the bottom of the servo motor 301 .

[0051] The front and back sides of the fixed trough plate 1 are movably connected with movable side inclined plates 303, and the top of the fixed trough plate 1 is fixedly connected with limiting plates 304. The movable side inclined plates 303 will increase the contact area between the fixed trough plate 1 and the ground due to the limiting effect of the limiting plates 304, and will play a role in hindering sinking. The front and back sides of the fixed trough plate 1 are provided with fixed soil boxes 305. The fixed soil box 305 is made of lightweight materials. When fixed to the inside of the soil, the inside of the fixed soil box 305 is filled with soil. The outer wall of the fixed soil box 305 is fixedly connected with the limiting fixing plate 306. Since the fixed soil box 305 is lighter as a whole, the limiting fixing plate 306 increases the contact area between the fixed soil box 305 and the ground, thereby playing a role in hindering the sinking of the fixed soil box 305.

[0052] A tension sensor 309 is fixedly connected to the top of the fixed soil box 305, a pull rope fixing block 308 is fixedly connected to the top of the limit plate 304, a tension rope 307 is fixedly connected to the outer side of the pull rope fixing block 308, and the tension rope 307 is fixedly connected to the corresponding tension sensor 309. When the fixed trough plate 1 sinks, the tension rope 307 will be pulled by the pull rope fixing block 308. When the tension rope 307 is pulled, the tension induction received by the tension sensor 309 becomes stronger. At this time, the tension sensor 309 sends an electrical signal to the two servo motors 301, so that the two servo motors 301 drive the corresponding spiral plates 302 to rotate until the tension sensed by the tension is the same as the original value, and the two servo motors 301 stop working.

[0053] When in use, when the equipment is outside, due to the arrival of rainfall, the soil structure of the ground will change, and the soil structure at the bottom of the fixed slot plate 1 will also change. The fixed slot plate 1 will sink slightly under the action of its own weight, and the movable side inclined plate 303 will increase the contact area between the fixed slot plate 1 and the ground due to the limiting effect of the limiting plate 304, which will play a role in hindering the sinking. Since the fixed soil box 305 is lighter as a whole, the limiting fixing plate 306 can play a role in hindering the sinking of the fixed soil box 305. At this time, when the fixed slot plate 1 sinks, the pull rope 307 will be pulled by the pull rope fixing block 308. The pull rope 307 is pulled, and the tension sensor The tension sensor 309 receives becomes stronger. At this time, the tension sensor 309 sends an electrical signal to the two servo motors 301, so that the two servo motors 301 drive the corresponding spiral plates 302 to rotate until the tension sensed by the tension is the same as the original value. The rotation of the spiral plate 302 will push the fixed slot plate 1 upward. When the fixed slot plate 1 moves upward, the movable side inclined plate 303 will move in the direction of the downward fall well 212 under the action of the soil inside the fixed soil box 305, and will push part of the soil inside the fixed soil box 305 into the bottom of the fixed slot plate 1 to stabilize the amount of soil at the bottom of the fixed slot plate 1 to avoid excessive sinking of the fixed slot plate 1.

[0054] When it rains, rainwater that falls on the top of the fixed trough plate 1 can be discharged into the deeper soil through the water drainage pipe 213 at the bottom of the fall well 212, so that the soil at the bottom of the fixed trough plate 1 remains relatively dry, which can further prevent the fixed trough plate 1 from settling. When the fixed trough plate 1 settles and the servo motor 301 drives the spiral plate 302 to lift the fixed trough plate 1, the water drainage pipe 213 drains the water into the deeper soil, preventing the water from making the soil at the bottom of the fixed trough plate 1 hollow, allowing the spiral plate 302 to push the fixed trough plate 1 upward more stably, and better preventing the fixed trough plate 1 from settling.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
