Description

Technical Field

[0001] This invention relates to an installation device for inclinometers applicable to various civil engineering structures such as bridges and buildings, and more particularly to an auxiliary device for installing inclinometers. Background Technology

[0002] An inclinometer is an accelerometer that uses the principle of inertia to measure the absolute angle of rotation of an object relative to a reference position or its relative angle of rotation at different times, monitoring changes in the tilt angle in real time. Based on Newton's second law, within a system, velocity cannot be measured, but acceleration can. When the inclinometer is stationary, there is no acceleration in either the horizontal or vertical directions; only gravitational acceleration acts on it. The angle between the vertical axis of gravity and the sensitive axis of the accelerometer is its tilt angle. An inclinometer typically consists of an angle chip and a conversion circuit. When the structure of the object being measured tilts, the output of the angle chip changes, the circuit analyzes the change, and thus calculates the offset angle relative to the vertical.

[0003] Inclinometers enable long-distance data transmission, ensuring the storage and processing of digital information. They are suitable for long-term installation or embedding inside or on the surface of structures such as concrete dams, road bridges, tunnel slopes, embankment pits, and buildings to measure the tilt of structures, facilitating the automation of tilt measurement.

[0004] Inclination measurement is a crucial component of structural health monitoring, and with advancements in measurement and control technology, the required accuracy of these systems is constantly increasing. However, in practical applications, inclination measurement still faces various challenges, including: low measurement accuracy (or high accuracy only at small angles), stringent requirements for key components, demanding operating environment conditions, and low reliability in harsh service environments. Furthermore, the installation of inclinometers is complex, requiring adjustments to the installation angle to ensure subsequent measurement accuracy. In some cases, limited operating space further complicates installation, making it difficult for installers. Additionally, the harsh operating environment of inclinometers makes them susceptible to damage during service.

[0005] The installation of an inclinometer is complex, requiring precise adjustment of its installation angle to ensure measurement accuracy. In some cases, the operating space for installation is limited, making installation even more difficult and unsuitable for operators. Furthermore, the inclinometer operates in harsh environments, and its measurement accuracy is easily affected by these conditions.

[0006] To address the issues of complex operation and low reliability of inclinometers in complex service environments during installation in existing civil engineering structures, an auxiliary device for inclinometer installation is needed. This device automatically adjusts the installation angle of the inclinometer by adjusting the air pressure of each airbag. After installation, the airbags and housing protect the inclinometer from external environmental interference during operation, ensuring its safe service. Summary of the Invention

[0007] To address the aforementioned technical challenges, this invention provides an auxiliary device for installing an inclinometer. It utilizes pressure changes within the airbags to adjust the inclinometer's installation angle. Furthermore, leveraging the superior ability of neural network models to establish complex relationship models, it achieves automatic adjustment of the airbag pressure, thereby automatically adjusting the inclinometer's installation angle. After adjusting the inclinometer's installation angle, the device uses inflatable airbags and a housing to protect the installed inclinometer, preventing it from being affected by harsh operating environments during operation. This device is easy to operate, effectively ensuring the inclinometer's data acquisition accuracy and protecting its operational safety.

[0008] To achieve the above objectives, the technical solution of the present invention is: an auxiliary device for installing an inclinometer, comprising a housing, airbag A, airbag B, airbag C, intelligent valves, pipes, and a control center; airbag A is attached to the corner of each wall panel of the housing, airbag B is attached to the middle of the side of each wall panel of the housing, and airbag C is attached to the center of each wall panel of the housing; multiple intelligent valves are embedded in each side panel of the housing, and the intelligent valves are connected to the control center through pipes; airbags A, B, and C are respectively connected to the intelligent valves, the inclinometer is placed in the middle of each airbag and is surrounded by multiple airbags, and the inclinometer is connected to the control center through an inclinometer signal line.

[0009] Furthermore, the control center includes a controller, an air pump, and a gas storage tank; the controller connects the air pump and the smart valves to control the working status of the air pump and the working status of each smart valve; the air pump connects to each airbag through the smart valves to fill the airbags with high-pressure gas; the gas storage tank stores high-pressure gas.

[0010] Furthermore, the controller incorporates a neural network model, which establishes the relationship between the air pressure of each airbag and the tilt angle of the tilt meter.

[0011] Furthermore, during the installation of the inclinometer, the housing is fixed to the reserved bracket or the structure to be measured via connecting screw holes. The inclinometer is placed in the middle of each airbag, and each airbag is inflated to make the air pressure in each airbag equal. The controller measures the initial angle value of the inclinometer. Based on the relationship between the air pressure value of each airbag and the change value of the inclinometer angle, the controller adjusts the air pressure of each airbag through the intelligent valve. Then, the angle value of the inclinometer is measured again. Based on the relationship between the air pressure value of each airbag and the change value of the inclinometer angle, the air pressure of each airbag is adjusted again to achieve an initial angle value of 0 for the inclinometer. Subsequently, the connection between the pipeline and the intelligent valve is disconnected, the intelligent valve automatically closes, and the housing and airbags protect the inclinometer for safe operation.

[0012] Furthermore, the pipeline includes a gas delivery hose and a signal line. At the end connected to the control center, the gas delivery hose is connected to a gas storage tank, and the signal line is connected to a controller.

[0013] Furthermore, the intelligent valve adjusts the air pressure in each airbag according to the electrical signal from the control center. In addition, the intelligent valve has a self-sealing function, which can prevent the gas in the airbag from leaking out after the pipeline is removed.

[0014] Furthermore, when airbags A, B, and C are attached to the wall panels of the box, a certain gap is left between each airbag, and a certain distance is left between airbags A and B and the edges of each wall panel to facilitate the inflation and deformation of each airbag.

[0015] The beneficial effects of this invention are:

[0016] 1. The device of the present invention uses airbag compression to adjust the installation angle of the inclinometer, avoiding mechanical or adhesive connections, facilitating the disassembly of the inclinometer, preventing damage to the inclinometer during disassembly, and promoting the reuse of the inclinometer.

[0017] 2. All production and assembly of the device of the present invention can be carried out in the factory, which is convenient for on-site operation and avoids the problems of difficult installation and low installation accuracy of inclinometer under limited work space.

[0018] 3. After the inclinometer is installed, the device of the present invention can be directly used to protect the inclinometer's service safety and avoid the inclinometer being affected by harsh environments during its service. Attached Figure Description

[0027] To facilitate accurate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0028] The auxiliary device of this invention includes a housing 1, a connecting screw hole 2, an airbag A3, an airbag B4, an airbag C5, an intelligent valve 6, a pipe 7, and a control center 8, as shown below. Figures 1 to 7 As shown.

[0029] The control center 8 includes a controller 9, an air pump 10, and an air storage tank 11. The controller 9 controls the operating status of the air pump 10 and the operating status of each intelligent valve 6. The air pump 10 generates high-pressure gas. The air storage tank 11 stores high-pressure gas, such as... Figure 6 , 7 As shown.

[0030] Box 1 is connected to the reserved bracket or the structure to be tested via connecting screw holes, such as... Figure 1 As shown.

[0031] Airbag A3 is attached to the corner of each wall panel of box body 1, airbag B4 is attached to the side of each wall panel of box body 1, and airbag C5 is attached to the middle of each wall panel of box body 1. Each side panel has 4 airbags A3, 4 airbags B4, and 1 airbag C5 attached. Figure 2 , Figure 3 (a), (b), (c), (d) Figure 5 As shown in (a), (b), (c), and (d) in the figure.

[0032] When airbags A3, B4, and C5 are attached to the wall panels of housing 1, a certain gap is left between each airbag, and a certain distance is left between airbags A3 and B4 and the edges of each wall panel to facilitate the inflation and deformation of each airbag. Figure 2 , Figure 3 (a), (b), (c), (d) Figure 5 As shown in (a), (b), (c), and (d) in the figure.

[0033] Airbags A3, B4, and C5 are connected to intelligent valves 6, which are embedded in the wall panels of the housing 1. Nine intelligent valves 6 are installed on each side wall panel. Figure 2 , Figure 3 (a), (b), (c), (d) Figure 5 As shown in (a), (b), (c), and (d) in the figure.

[0034] Intelligent valve 6 is connected to one end of pipe 7; the other end of pipe 7 is connected to the control center, such as... Figure 6 As shown.

[0035] The inclinometer is placed in the middle of each airbag and is surrounded by 54 airbags. The inclinometer is connected to the control center 8 via an inclinometer signal line.

[0036] Pipeline 7 includes a gas delivery hose and a signal line, which can deliver gas and transmit signals. The signals are used to control the opening and closing of the intelligent valve 6. At the end connected to the control center 8, the gas delivery hose is connected to the gas storage tank 11, and the signal line is connected to the controller 9. The gas storage tank 11 supplies high-pressure gas to each gas bladder through the gas delivery hose, such as... Figure 6 As shown.

[0037] The intelligent valve 6 senses the air pressure inside the airbag in real time and transmits the signal to the control center 8. Furthermore, the intelligent valve 6 adjusts the air pressure inside each airbag based on the electrical signal fed back by the control center 8. In addition, the intelligent valve 6 has a self-sealing function, which can prevent the gas inside the airbag from leaking out after the pipe 7 is removed.

[0038] The controller 9 embeds a neural network model that establishes the relationship between the air pressure of each airbag and the tilt angle of the inclinometer. During the pre-training phase of the neural network, the inclinometer is placed between the airbags. First, the air pump 10 generates high-pressure gas, which is stored in the air tank 11. The controller 9 then controls the smart valve 6 to open, inflating each airbag to equalize the air pressure. The controller 9 then collects the initial angle value of the inclinometer. Next, the controller 9 controls the smart valve 6 to inflate each airbag individually, controlling the air pressure of each airbag to reach the set value. The inclinometer angle value is collected again, and this variable is calculated. By randomly generating a series of air pressure values ​​and measuring the corresponding changes in angle values, the neural network is used to establish the relationship between the air pressure values ​​of each airbag and the changes in the inclinometer angle.

[0039] When installing the inclinometer, the housing 1 is fixed to the reserved bracket or the structure to be measured via the connecting screw holes 2. The inclinometer is placed in the middle of each airbag, and each airbag is inflated to equalize the air pressure inside. The controller 9 measures the initial angle value of the inclinometer. Based on the relationship between the airbag pressure values ​​and the inclinometer angle change value, the controller 9 adjusts the air pressure of each airbag via the intelligent valve 6. Then, the inclinometer angle value is measured again, and the airbag pressure is adjusted again based on the relationship between the airbag pressure values ​​and the inclinometer angle change value to achieve an initial angle value of 0 for the inclinometer. Subsequently, the connection between the pipe 7 and the intelligent valve 6 is disconnected, and the intelligent valve 6 automatically closes, protecting the inclinometer's operational safety by housing 1 and the airbags.

[0040] The following aspects need to be noted in this embodiment:

[0041] 1. When installing the inclinometer with this device, ensure that the gas in each airbag has sufficient pressure to avoid the inclinometer not being completely fixed after debugging and thus moving.

[0042] 2. Each airbag should have sufficient strength to prevent rupture under high pressure;

[0043] 3. When inflating each airbag to adjust the tilt angle, the tilt angle should be measured after it has stabilized to avoid changes in the tilt angle within a short period of time.

[0044] Fourth, when training a neural network model, a sufficient number of random samples should be generated to ensure the training accuracy of the neural network model;

[0045] 5. When removing auxiliary devices, the intelligent valves should be opened first to release the high-pressure gas in each airbag to avoid injury to operators during the removal process.

[0046] The above description represents preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements without departing from the principles of the present invention, and these improvements should also be considered within the scope of protection of the present invention.
