Description

Technical Field

[0001] This invention belongs to the field of settlement monitoring technology, and specifically relates to a building settlement monitoring device. Background Technology

[0002] Building axis survey, or building settlement monitoring, is applicable to industrial and civil buildings. In industrial and civil buildings, in order to understand the building's settlement, promptly detect any adverse settlement phenomena so that measures can be taken to ensure the building's safe use, and also provide data for future rational design, settlement monitoring must be conducted during the building's construction and after it is put into operation.

[0003] Therefore, many settlement monitoring devices have emerged in the prior art. For example, a building settlement intelligent monitoring device with patent number CN202211299740.0 includes a support base and a support leg fixedly connected to the bottom end of the support base by a bolt assembly. A connecting shell is fixedly connected to the top end of the support base by a bolt assembly. A third slider is slidably connected inside the connecting shell. A first connecting block is fixedly connected to the top end of the third slider by a bolt assembly. A scale strip is provided on one side of the outer wall of the first connecting block. A conductive seat is installed inside the connecting shell. A grounding block is installed at the bottom end of the third slider, and the bottom end of the grounding block contacts the conductive seat. An alarm light is installed on one side of the outer wall of the connecting shell. A support leg reinforcement mechanism penetrating into the interior of the support leg is provided at the top end of the support base to improve the stability of the support base.

[0004] The aforementioned devices are complex in structure and expensive, making them unsuitable for widespread use in the construction industry. In addition, existing technologies also use components such as total stations to detect settlement, but this method is usually operated manually and requires periodic testing. The operation steps and processes are complex, and continuous visual monitoring is not possible. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a building settlement monitoring device to solve the problems of complex structure of existing settlement monitoring devices, which are not conducive to widespread use, and the difficulty in continuously and visually monitoring building settlement.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention discloses a building settlement monitoring device, which is installed on at least two mutually perpendicular exterior wall sides of a building. It includes an installation rod with a sliding sleeve fitted onto it. The sliding sleeve has a telescopic rod perpendicularly connected to it. The telescopic rod includes a hollow outer fixed rod, an inner sliding rod, and a telescopic spring. One end of the outer fixed rod is fixed to the sliding sleeve. The telescopic spring is disposed inside the outer fixed rod. One end of the inner sliding rod is slidably connected to the inside of the outer fixed rod, and its end abuts against one end of the telescopic spring. The other end of the inner sliding rod has a rotating rod, one end of which is rotatably connected to the other end of the inner sliding rod. The central axis of the installation rod lies within the rotation plane of the rotating rod. The rotating rod has a fixing structure for fixing the rotating rod to the building's exterior wall.

[0008] Furthermore, the fixing structure includes a fixing plate and fixing bolts. The fixing bolts are disposed on both sides of the fixing plate, and the fixing plate, under the action of the fixing bolts, presses and fixes the rotating rod to the exterior wall of the building.

[0009] Furthermore, the mounting rod is equipped with an alarm system, which includes a buzzer assembly and a piezoelectric trigger assembly for controlling the energization of the buzzer assembly. The piezoelectric trigger assembly includes a settlement piezoelectric trigger structure, a tilt piezoelectric trigger structure, and an actuator. The buzzer assembly includes a battery, a buzzer, and a control switch connected in series. When the building settles to a threshold range, the actuator actuates the control switch under the action of the settlement piezoelectric trigger structure, causing the control switch to close and become energized. When the building tilts to a threshold range, the actuator actuates the control switch under the action of the tilt piezoelectric trigger structure, causing the control switch to close and become energized.

[0010] Furthermore, the settling piezoelectric triggering structure includes a first mounting ring, the middle of which is fixed to the mounting rod. A first piezoelectric ceramic is provided on the first mounting ring, and both the first mounting ring and the first piezoelectric ceramic are located below the sliding sleeve.

[0011] Furthermore, the inner ring of the first mounting ring is threaded onto the outer surface of the mounting rod.

[0012] Furthermore, the tilting piezoelectric triggering structure includes a second mounting ring, a third mounting ring, a second piezoelectric ceramic, a conical spring, a sliding sleeve, and a traction rope. The inner rings of both the second and third mounting rings are provided with fixing blocks, which fix the second and third mounting rings to the mounting rod. The sliding sleeve has a strip-shaped notch that matches the fixing block. The sliding sleeve is fitted onto the mounting rod, and the fixing block is located inside the strip-shaped notch. The second and third mounting rings are sequentially arranged above the sliding sleeve. The second piezoelectric ceramic is disposed on the outer surface of the sliding sleeve between the second and third mounting rings. One end of the conical spring is fixed to the second mounting ring, and the other end of the conical spring is fixed to the outer surface of the sliding sleeve below the second mounting ring. One end of the traction rope is connected to the end of the sliding sleeve above the third mounting ring, and the other end of the traction rope is connected to the upper end of the rotating rod.

[0013] Furthermore, the upper surface of the third mounting ring is symmetrically provided with support rods, one end of the support rod is fixed to the third mounting ring, and the other end of the support rod is provided with a guide ring fixedly connected thereto. The traction rope passes through the middle of the guide ring and is connected to the rotating rod.

[0014] Furthermore, a mounting plate is provided at one end of the rotating rod connected to the traction rope. One end of the mounting plate is fixed to the end of the rotating rod. A vertically arranged column is provided at the other end of the mounting plate. A slider is provided on the column. One end of the traction rope is fixed to the slider. An arc-shaped slide is provided on the third mounting plate. The column is located inside the arc-shaped slide, and the slider is placed on the arc-shaped slide.

[0015] Furthermore, the arc-shaped slide is composed of symmetrically arranged arc-shaped tubes.

[0016] Furthermore, the lower end of the mounting rod is provided with a tapered tip.

[0017] The beneficial effects of this invention are as follows:

[0018] (1) The settlement monitoring device in this technical solution has a simple structure and ingenious principle, and can accurately monitor the changes in settlement and tilt of buildings in a visual manner.

[0019] (2) When the building tilts, it will cause the inner sliding rod to compress the spring and slide, thereby achieving extension or shortening. That is, when tilting, it will not directly transmit all the torque to the mounting rod, which will not destroy the initial fixed position of the mounting rod, and will not affect the accuracy of the measurement.

[0020] (3) At the same time, the sliding sleeve can rotate around the installation rod. That is, when the building tilts in other directions, the rotating rod can rotate around the installation rod, which can prevent the rotational torque from being transmitted to the installation rod to a certain extent, thus protecting the stability of the installation rod and preventing the telescopic rod from bending and being damaged to a certain extent.

[0021] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0031] like Figures 1-6 As shown, this invention discloses a building settlement monitoring device, which is installed on at least two mutually perpendicular exterior walls 1 of a building. Since two perpendicular walls allow for monitoring of tilt in all directions, it is preferable to install one settlement monitoring device on each wall of the building. This makes the detection structure more accurate and comprehensive. Specifically, the settlement monitoring device includes a mounting rod 2, which can be understood as a steel pipe. A sliding sleeve 3 is fitted onto the mounting rod 2. Preferably, the inner diameter of the sliding sleeve 3 is larger than the outer diameter of the mounting rod 2. This has the advantage that even if the rotating rod 7 tilts to a certain extent, when the building settles, the tilt will not be affected by the transmission of the rotating rod 7. The change in the direction of the force transfer leads to a decrease in the sliding effect of the sliding sleeve 3. To address this, a telescopic rod is provided on the sliding sleeve 3 and connected perpendicularly to it. The telescopic rod includes a hollow outer fixed rod 4, an inner sliding rod 5, and a telescopic spring 6. One end of the outer fixed rod 4 is fixed to the sliding sleeve 3. The telescopic spring 6 is located inside the outer fixed rod 4. One end of the inner sliding rod 5 is slidably connected to the inside of the outer fixed rod 4, and its end abuts against one end of the telescopic spring 6. The other end of the inner sliding rod 5 is provided with a rotating rod 7. One end of the rotating rod 7 is rotatably connected to the other end of the inner sliding rod 5, and the central axis of the mounting rod 2 is in the rotation plane of the rotating rod 7. The rotating rod 7 is provided with a fixing structure to fix the rotating rod 7 to the building exterior wall 1.

[0032] The working principle of the above technical solution is as follows:

[0033] When installing this device, the first step is to align the mounting rod 2 parallel to the building to be monitored. Then, the rotating rod 7 is fixed to the building's exterior wall 1 using a fixing structure. It is important to note that the rotating rod 7 and the telescopic rod are preferably arranged perpendicularly. When the building subsides, the rotating rod 7 will descend, which in turn will cause the telescopic rod and the sliding sleeve 3 to descend. Therefore, the amount of building settlement can be determined by observing the change in position of the sliding sleeve 3 on the mounting rod 2. Simultaneously, if the building tilts (here, tilt refers to tilting towards the mounting rod 2; tilting in other directions can be detected by monitoring devices on other surfaces), the rotating rod 7 will rotate. The tilt angle of the building can be measured by observing the change in angle between the rotating rod 7 and the telescopic rod. It is easy to understand that distance scale lines can be set on the mounting rod 2 for easier observation. An angle scale can also be set at the connection between the telescopic rod and the rotating rod 7 to observe changes in the building's tilt angle.

[0034] It should be noted that the main purpose of the above-described configuration of the telescopic pole is to ensure that when the building tilts, the inner sliding rod 5 will compress the spring and slide, thereby extending or shortening. This prevents the entire torque from being directly transmitted to the mounting rod 2 during tilting, thus preserving the initial fixed position of the mounting rod 2 and maintaining measurement accuracy. Simultaneously, the sliding sleeve 3 can rotate around the mounting rod 2. When the building tilts in other directions, the rotating rod 7 can rotate around the mounting rod 2, which to some extent prevents rotational torque from being transmitted to the mounting rod 2, protecting its stability and preventing bending damage to the telescopic pole.

[0035] In one feasible method, the fixing structure includes a fixing plate 8 and fixing bolts 9. The fixing bolts 9 are located on both sides of the fixing plate 8. Under the action of the fixing bolts 9, the fixing plate 8 presses and fixes the rotating rod 7 to the building exterior wall 1. This fixing method is relatively simple and stable. Of course, bonding or other methods can also be used.

[0036] In one feasible embodiment, the mounting rod 2 is equipped with an alarm system. The purpose of the alarm system is to alert staff or residents that the building's tilt and settlement are too extreme, requiring immediate action or evacuation. The alarm system includes a buzzer assembly and a piezoelectric trigger assembly for controlling the energization of the buzzer assembly. The piezoelectric trigger assembly includes a settlement piezoelectric trigger structure, a tilt piezoelectric trigger structure, and an actuator 27. The settlement and tilt piezoelectric trigger structures are connected in parallel with the actuator 27, meaning that regardless of which one reaches the trigger condition, it can control the actuator 27 to operate. In a specific implementation, a miniature linear motor can be used. The extension of the telescopic rod closes the control switch 28. The buzzer assembly includes a battery 30, a buzzer 29, and a control switch 28 connected in series. When the building settles to a threshold range, such as 5cm, the actuator 27 actuates the control switch 28 under the action of the settlement piezoelectric triggering structure, causing the control switch 28 to close and be energized. When the building tilts to a threshold range, such as a tilt angle of 10°, the actuator 27 actuates the control switch 28 under the action of the tilt piezoelectric triggering structure, causing the control switch 28 to close and be energized.

[0037] It should be noted that when pressure or tension is applied to a piezoelectric ceramic, it undergoes a slight deformation, causing a redistribution of charges within the crystal and generating a potential difference. This potential difference can be extracted through electrodes to form a voltage signal. Therefore, by applying external force, the piezoelectric ceramic can convert mechanical energy into electrical energy, thus generating electricity under pressure to control the operation of actuator 27. The power generation circuit of the piezoelectric ceramic is existing technology and involves other electrical components, which will not be elaborated upon here.

[0038] In one feasible embodiment, the settlement piezoelectric triggering structure includes a first mounting ring 10, the middle of which is fixed to the mounting rod 2. A first piezoelectric ceramic 11 is provided on the first mounting ring 10. Both the first mounting ring 10 and the first piezoelectric ceramic 11 are located below the sliding sleeve 3. When the building settles to a certain extent, it will cause the sliding sleeve 3 to move down and come into contact with the first piezoelectric ceramic 11. This will cause the piezoelectric ceramic to generate electricity, and the current will be transmitted to the actuator 27 through the connecting wire 26, thereby enabling the actuator 27 to work and triggering the alarm system.

[0039] In one feasible embodiment, the inner ring of the first mounting ring 10 is threadedly connected to the outer surface of the mounting rod 2. The position of the first mounting ring 10 on the mounting rod 2 can be changed by rotation, thereby adjusting the position of the first piezoelectric ceramic 11 according to the height of the installation ground, and thus also changing the trigger height and range of the trigger settlement height.

[0040] In one feasible embodiment, the tilting piezoelectric triggering structure includes a second mounting ring 12, a third mounting ring 16, a second piezoelectric ceramic 17, a conical spring 13, a sliding sleeve 14, and a traction rope 20. Both the second mounting ring 12 and the third mounting ring 16 have fixing blocks 25 (protrusions) on their inner rings. The fixing blocks 25 fix the second mounting ring 12 and the third mounting ring 16 to the mounting rod 2. The sliding sleeve 14 has a strip-shaped notch 15 that matches the fixing block 25. The sliding sleeve 14 is sleeved onto the mounting rod 2, and the fixing block 25 is located at the strip-shaped notch. Inside 15, the second mounting ring 12 and the third mounting ring 16 are sequentially arranged above the sliding sleeve 3. The second piezoelectric ceramic 17 is arranged on the outer surface of the sliding sleeve 14 between the second mounting ring 12 and the third mounting ring 16. One end of the conical spring 13 is fixed to the second mounting ring 12, and the other end of the conical spring 13 is fixed to the outer surface of the sliding sleeve 14 below the second mounting ring 12. One end of the traction rope 20 is connected to the end of the sliding sleeve 14 above the third mounting ring 16, and the other end of the traction rope 20 is connected to the upper end of the rotating rod 7.

[0041] It should be noted that during installation, the position of the telescopic sleeve on the mounting rod 2 can be controlled by adjusting the length of the traction rope 20. This allows control of the position of the second piezoelectric ceramic 17 between the second mounting ring 12 and the third mounting ring 16, thus adjusting the trigger distance. Because the traction rope 20 provides tension to the telescopic sleeve, and the conical spring 13 provides a reverse thrust, they achieve a balance. When the building tilts towards the mounting rod 2, the distance between the building and the mounting rod 2 shortens, causing the traction rope 20 to retract under the force of the conical spring 13. This causes the telescopic sleeve to slide towards the lower end of the mounting rod 2. When it slides a certain distance... When the structure tilts, the piezoelectric ceramic 17 will come into contact with the second mounting ring 12, thereby generating electricity through compression. Similarly, when the building tilts due to the principle of the mounting rod 2, the traction rope 20 will overcome the force of the conical spring 13 and stretch, thus driving the sliding sleeve 14 to move upward, eventually causing the second piezoelectric ceramic 17 and the third mounting ring 16 to come into contact and generate electricity. Of course, it is easy to understand that two second piezoelectric ceramics 17 can also be set, with their pressing and generating end faces facing the second mounting ring 12 and the third mounting ring 16 respectively, so as to perform power generation operation in the two tilt directions respectively. The second piezoelectric ceramic 17 only needs to be fixed on the sliding sleeve 14. As for its fixing and setting method, it is existing technology and will not be described in detail here.

[0042] In one feasible embodiment, a support rod 18 is symmetrically provided on the upper surface of the third mounting ring 16. One end of the support rod 18 is fixed to the third mounting ring 16, and a guide ring 19 is fixedly connected to the other end of the support rod 18. The traction rope 20 passes through the middle of the guide ring 19 and is connected to the rotating rod 7. The support rod 18 guides the traction rope 20 to a height close to the end of the rotating rod 7, thereby guiding the movement path of the traction rope 20 and improving the movement effect of the traction rope 20 driving the sliding sleeve 14.

[0043] In one feasible embodiment, a mounting plate 21 is provided at one end of the rotating rod 7 connected to the traction rope 20. One end of the mounting plate 21 is fixed to the end of the rotating rod 7, and a vertically arranged column 23 is provided at the other end of the mounting plate 21. A slider 22 is provided on the column 23, and one end of the traction rope 20 is fixed to the slider 22. An arc-shaped slide 24 is provided on the third mounting plate 21, and the column 23 is located in the arc-shaped slide 24. The slider 22 is placed on the arc-shaped slide 24. It is easy to understand that when settlement occurs, the traction rope will also move, which will cause the position of the second power generation ceramic to change, thus changing the triggering condition for tilt power generation. However, under the action of this device, since the fixed rod is installed on the outside of the building foundation, it is not easy to settle, that is, the height of the mounting rod 2 will not change. Therefore, under the support of the arc-shaped slide 24, even if the building settles, the slider 22 will slide on the column 23, that is, the initial height of the slider 22 will not change, that is, the triggering condition for tilt alarm will not change, thus eliminating the influence of settlement on the triggering timing of tilt alarm.

[0044] In one feasible embodiment, the arc-shaped slide 24 consists of symmetrically arranged arc-shaped tubes.

[0045] In one feasible method, the lower end of the mounting rod is provided with a tapered tip. The cylindrical tip is mainly for fixing the mounting rod 2 to the ground. Of course, other methods can also be used for fixing, such as fixing with anchor bolts in the prior art.

[0046] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
