Abstract
Description
Technical Field
[0001] This application belongs to the field of building construction technology, specifically relating to a settlement monitoring device. Background Technology
[0002] Settlement monitoring is a crucial aspect of ensuring structural safety during the construction and operation phases of a building. Buildings experience settlement due to factors such as uneven soil conditions, load variations, and groundwater activity. Uneven or excessive settlement can easily lead to serious consequences such as structural cracking, tilting, or even collapse. Therefore, continuous and accurate monitoring is essential for early warning systems.
[0003] Currently, hydrostatic levels are commonly used in engineering for automated settlement monitoring. This system connects liquid tanks at various measuring points via pipelines, uses distance sensors to measure changes in liquid level relative to a reference point, calculates the settlement, and can remotely transmit the data to a monitoring center.
[0004] However, the inventors have discovered that existing devices, in order to capture minute changes in settlement, must rely on expensive, high-precision sensors, resulting in high overall costs. Furthermore, in complex field environments, the accuracy of these sensors is highly susceptible to temperature fluctuations and electromagnetic interference, causing deviations in the monitoring data and compromising reliability. Utility Model Content

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0007] A settlement monitoring device is provided, comprising:
[0008] The positioning seat is used to be installed on the exterior wall of the building and is fixed to the wall by a pre-embedded structure;
[0009] A support base, used to be fixed to the ground outside the settlement area of a building, has a support arm on its upper side; the upper end of the support arm is rotatably connected to a lever arm in the horizontal direction, the rotation axis of which is perpendicular to the direction of the support base toward the positioning seat, and one end of the lever arm is hinged to the positioning seat so that the lever arm swings when the building settles; and
[0010] A distance sensor is connected to the end of the lever arm away from the positioning seat via a self-hanging structure, so that the detection end of the distance sensor faces downward and changes in value when the lever arm swings;
[0011] The distance between the distance sensor and the rotating connection point of the lever arm is greater than the distance between the positioning seat and the rotating connection point of the lever arm.
[0012] In one possible implementation, the embedded structure includes:
[0013] Two pre-reserved slots, both for installation on the exterior wall of the building, are arranged side-by-side horizontally; and
[0014] Positioning ribs are used to be installed on the outside of the building. Both ends of the ribs have bent portions, and the two bent portions are respectively inserted into the two reserved slots.
[0015] The positioning seat has a C-shaped fastener; the fastener is used to engage with the outer periphery of the positioning rib to fix the positioning seat.
[0016] In one possible implementation, the positioning seat also has two limiting plates extending toward the positioning rib, and the two limiting plates are respectively located on the upper and lower sides of the positioning rib.
[0017] Each of the limiting plates has a fixing nut that is fixedly connected to it, and a tightening bolt that is threadedly connected to the fixing nut and used to abut against the exterior wall of the building.

[0021] In one possible implementation, the hook has a downwardly extending suspension rope, and the distance sensor is fixedly connected to the extension end of the suspension rope.
[0022] In one possible implementation, a counterweight is fixedly mounted on the suspension rope.
[0023] In one possible implementation, the distance sensor is a photoelectric sensor, and the support base is also provided with a receiver that cooperates with the output beam of the photoelectric sensor.
[0024] In one possible implementation, the support arm is tilted from bottom to top toward the side where the positioning seat is located;
[0025] The receiving base is disposed on the inclined surface of the support arm, has the degree of freedom to move in the inclined direction, and is connected to the support arm by a locking structure.
[0026] In one possible implementation, the locking structure includes:
[0027] Multiple through holes are formed on the support arm and are spaced apart along the length of the support arm; and
[0028] A boss is provided on the receiving base and is adapted to be embedded in any of the through holes therein;
[0029] A baffle is detachably connected to the embedded surface of the boss; when the baffle is connected to the boss, the baffle abuts against the side of the support arm facing away from the receiver, so as to restrict the movement of the receiver relative to the support arm.

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0053] Please refer to the following: Figures 1 to 13 The settlement monitoring device provided in this application will now be described. The settlement monitoring device proposed in this application includes a positioning base 1, a support base 2, and a distance sensor 3.
[0054] The positioning seat 1 is used to be installed on the exterior wall of the building and is fixed to the wall by the pre-embedded structure 10; wherein, the pre-embedded structure 10 is a basic structure directly fixed to the building, and the positioning seat 1 is an additional structure fixed on this basic structure.
[0055] The support 2 is used to fix the support on the ground outside the settlement area of the building, and the settlement of the building will not affect the stability of the support 2.
[0056] The upper side of the support base 2 has an upwardly extending support arm 21. The upper end of the support arm 21 is rotatably connected to a lever arm 22 in the horizontal direction. The rotation axis of the lever arm 22 is perpendicular to the direction of the support base 2 toward the positioning seat 1, and the connection point is located between the two ends of the lever arm 22. In this embodiment, for ease of description, the end of the lever arm 22 closer to the positioning seat 1 is defined as its inner end, and the other end is defined as its outer end.
[0057] The inner end of the lever arm 22 is hinged to the positioning seat 1, and its hinge axis is parallel to the rotation axis of the lever arm 22, so that the lever arm 22 swings synchronously when the building settles.
[0058] The distance sensor 3 is connected to the end of the lever arm 22 away from the positioning seat 1 (i.e., the outer end of the lever arm 22) through a self-hanging structure 4, so that the sensor detection end is kept facing downwards and outputs a change in value when the lever arm 22 swings.
[0059] The distance between the distance sensor 3 and the rotational connection point of the lever arm 22 is greater than the distance between the positioning seat 1 and the rotational connection point of the lever arm 22, that is, the distance between the distance sensor 3 and the outer end of the lever arm 22 is greater than the distance between the distance sensor 3 and the inner end of the lever arm 22; for example Figure 9 As shown, α is greater than β.
[0060] In this embodiment, the positioning seat 1 is fixed to the outer wall of the building through the pre-embedded structure 10 to ensure the structural stability of the device after installation; at the same time, the distance sensor 3 is connected to the lever arm 22 through the self-hanging structure 4 to ensure that the value obtained by the distance sensor 3 reflects the vertical distance in real time, so as to facilitate subsequent calculation.
[0061] In this design, the lever arm 22 and the distance sensor 3 are designed in a coordinated manner to mechanically amplify the small actual settlement amount, thereby enabling high-sensitivity monitoring using a sensor with conventional accuracy.
[0062] Compared with existing technologies, the settlement monitoring device provided in this embodiment significantly reduces the reliance on expensive high-precision sensors, saving costs; it also effectively avoids the technical defects of high-precision sensors being susceptible to interference and data inaccuracy in complex field environments, thereby improving the overall reliability and economy of settlement monitoring.
[0063] In some embodiments, such as Figure 4 and Figure 5 As shown, the embedded structure 10 includes two reserved slots 101 and positioning ribs 102.
[0064] Both reserved slots 101 are opened on the exterior wall of the building and are arranged side by side in the horizontal direction.
[0065] The positioning rib 102 is located on the outside of the building, and both ends of it have a bent portion 1021, and the two bent portions 1021 are respectively inserted into two reserved slots 101.
[0066] The positioning seat 1 has a C-shaped fastener 11; the fastener 11 is used to snap onto the outer periphery of the positioning rib 102 to fix the positioning seat 1.
[0067] In some embodiments, such as Figure 4 , Figure 6 and Figure 7 As shown, the positioning seat 1 also has two limiting plates 12 extending toward the positioning rib 102, and the two limiting plates 12 are respectively located on the upper and lower sides of the positioning rib 102.
[0068] Each limiting plate 12 has a fixing nut 121 fixedly connected to it, and a tightening bolt 122 threadedly connected to the fixing nut 121; the tightening bolt 122 is used to abut against the exterior wall of the building to restrict the positioning seat 1 from rotating about the positioning rib 102.
[0069] In some embodiments, such as Figure 13 As shown, the self-hanging structure 4 includes a connecting rod 41 and a hook 42.
[0070] The connecting rod 41 is fixedly mounted on the end face of the lever arm 22 away from the positioning seat 1, and its axis is parallel to the horizontal direction.
[0071] Hook 42 is attached to link 41 and is connected to distance sensor 3.
[0072] In actual use, the hook 42 swings relative to the connecting rod 41 under the combined action of its weight and that of the distance sensor 3, so that the detection end of the distance sensor 3 faces the same direction; before this, the weight distribution of each component on the distance sensor 3 is preset to ensure that the detection end faces downward.
[0073] In some embodiments, such as Figure 3 and Figure 10 As shown, the hook 42 has a downward-extending suspension rope 421, which is connected to the bottom of the hook 42, and the aforementioned distance sensor 3 is fixedly connected to the extension end of the suspension rope 421.
[0074] By lowering the distance sensor 3 using the sling 421, the situation where the distance sensor 3 cannot turn downwards in time due to the hook 42 and the connecting rod 41 getting stuck can be avoided.
[0075] In some embodiments, such as Figure 10 and Figure 13 As shown, a counterweight 422 is fixedly installed on the suspension rope 421. The counterweight 422 can increase the downward force applied by the distance sensor 3 to the suspension rope 421 to ensure that the distance sensor 3 remains facing downward.
[0076] In some embodiments, such as Figure 2 , Figure 3 and Figure 11 As shown, the distance sensor 3 is a photoelectric sensor, and the support base 2 is also equipped with a receiver base 5 that cooperates with the output beam of the photoelectric sensor.
[0077] In this embodiment, the photoelectric sensor can be a through-beam photoelectric sensor. Specifically, the through-beam photoelectric sensor includes a transmitter and a receiver. The transmitter is fixed to the end of the lever arm 22, and the receiver is fixed to the upward-facing side of the receiver base 5. Alternatively, the photoelectric sensor can also be a diffuse reflection photoelectric sensor, where the transmitter and receiver are integrated, and it operates by reflecting light from the ranging surface. In this case, a reflector can be installed on the upward-facing side of the receiver base 5 to ensure the light beam reflection effect and improve the detection accuracy.
[0078] In some embodiments, such as Figure 2 As shown, the support arm 21 tilts from bottom to top toward the side where the positioning seat 1 is located.
[0079] The receiver 5 is set on the inclined surface of the support arm 21; it has the freedom to move along the inclined direction during the debugging stage, and is connected to the support arm 21 through the locking structure 6, so as to realize its adaptive adjustment for the position of different distance sensors 3.
[0080] In some embodiments, such as Figure 8 , Figure 11 and Figure 12 As shown, the locking structure 6 includes multiple through holes 61 and bosses 62.
[0081] Multiple through holes 61 are formed on the support arm 21 and are spaced apart along the length direction of the support arm 21. In this embodiment, the support arm 21 includes two parallel arms and reinforcing ribs spaced apart between the two arms along the length direction. There is a gap between adjacent reinforcing ribs, and the gap forms the through hole 61.
[0082] The boss 62 is provided on the receiving seat 5, and as the position of the receiving seat 5 relative to the support arm 21 changes, the boss 62 is adapted to be embedded in any of the through holes 61 therein.
[0083] In order to fix the boss 62 relative to the support arm 21, a baffle 621 is detachably connected to the embedded surface of the boss 62. In this embodiment, the detachable connection is achieved by a screw pre-set on the boss 62, a through hole opened on the baffle 621, and a nut that is threaded with the screw and used to abut against the outer side of the baffle 621.
[0084] When the baffle 621 is connected to the boss 62, the baffle 621 abuts against the side of the support arm 21 facing away from the receiver 5, so as to restrict the movement of the receiver 5 relative to the support arm 21.
[0085] In some embodiments, such as Figure 8 As shown, an upwardly extending reinforcement 23 is fixedly provided on the support base 2. The reinforcement 23 can abut against the support arm 21 to improve the structural stability of the support arm 21 in the tilted state.
[0086] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
