Description

Technical Field

[0001] This utility model relates to the field of transition deformation monitoring technology, and in particular to a device for monitoring excessive deformation at the transition position of steel-concrete tower. Background Technology

[0002] Steel-concrete towers, which combine steel and concrete structures, are widely used in wind power generation, bridges, and transmission towers because they combine the advantages of both materials.

[0003] In reinforced concrete towers, the transition point between the steel column and the concrete column is a critical node for structural stress. This location bears complex stress transmission, and the physical properties of the two materials are quite different. During long-term service, the transition point can be affected by wind loads, temperature changes, and foundation settlement, leading to excessive deformation and threatening the overall structural safety of the tower.

[0004] To ensure tower safety, long-term real-time monitoring of deformation at the transition points is necessary. Current technology involves setting reference points and measurement points at different locations on the tower, and using laser rangefinders and tilt sensors for measurement.

[0005] However, since reinforced concrete towers are located in outdoor environments, the foundations on which monitoring devices are installed may experience slight attitude changes due to uneven settlement, vibration, and temperature creep. This can cause the measuring optical axis of the fixedly installed monitoring instruments to deviate from their preset target point, i.e., miss the target. Once this deviation occurs, the measurement data will be inaccurate or even completely lost, rendering the monitoring ineffective.

[0006] Most existing monitoring devices lack the ability to automatically calibrate attitude. After the aforementioned deviations occur, it is often necessary for professionals to climb the tower for expensive and time-consuming manual recalibration and alignment. This method has a slow response time and cannot meet the long-term monitoring requirements of large tower structures for automation, high precision, and high reliability.

[0007] Therefore, this utility model proposes a monitoring device for excessive deformation at the steel-concrete transition position of a steel-concrete tower to address the shortcomings of the prior art. Utility Model Content

[0008] In view of the problems existing in the monitoring device for excessive deformation at the steel-concrete transition position of steel-concrete towers, such as measurement miss due to changes in the tower foundation attitude, lack of automatic attitude calibration capability, reliance on manual alignment, and low monitoring reliability, this utility model aims to provide a steel-concrete tower excessive deformation monitoring device with an improved structure that can effectively solve the above problems.

[0009] This utility model provides a device for monitoring excessive deformation at the transition position of a steel-concrete tower, comprising: a top plate and a bottom plate; a rotating motor is fixedly connected to the top of the bottom plate; one end of a rotating rod is fixedly connected to the output end of the rotating motor; a connecting rod is rotatably connected to the outer wall of the rotating rod; a universal joint is fixedly connected to the top of the connecting rod; and a mounting plate is fixedly connected to the top of the universal joint. The system includes a gravity sensor disk located at the bottom of the mounting plate; a protective shell fixedly connected to the top of the mounting plate; and a laser rangefinder fixedly connected inside the protective shell.

[0010] The measuring optical axis of the laser rangefinder is oriented towards the top plate.

[0011] Furthermore, the rotating motor, rotating rod, connecting rod, universal joint, mounting plate, and gravity sensing disk form a coordinated automatic adjustment mechanism. The gravity sensing disk is located at the bottom of the mounting plate and is used to sense attitude changes in real time. The rotating motor drives the mounting plate to adjust its angle through the transmission structure composed of the rotating rod, connecting rod, and universal joint, so that the laser rangefinder fixed on the mounting plate can automatically align with the top plate based on the data from the gravity sensing disk.

[0012] Preferably, it also includes a rainproof shell, which is fixedly connected to the top outer wall of the base plate. The rainproof shell covers the rotating motor, rotating rod, connecting rod and universal joint outside of it, so as to protect them from outdoor rain and dust erosion and ensure the operational stability of the transmission mechanism.

[0013] Preferably, to enhance the protective effect, the rainproof shell is a cover-like structure with a closed top and surrounding sides. The bottom edge of the rainproof shell is fixedly connected to the top surface of the base plate. This structure allows the rainproof shell and the base plate to jointly define a protective space for housing the rotating motor, providing a reliable sealing and protective effect.

[0014] Preferably, it also includes a signal light, which is fixedly installed on the top of the rainproof shell, in a position that allows it to be observed by ground personnel. The signal light is electrically connected to the laser rangefinder so as to trigger a visual alarm when excessive deformation is detected, thereby achieving immediate early warning.

[0015] Preferably, the specific structure of the protective shell is defined as follows: the protective shell is a hollow structure, and the laser rangefinder is safely housed in the hollow part of the protective shell to prevent it from being impacted by external forces during installation and maintenance. To ensure the measurement function, a laser through hole is provided on the top of the protective shell, and the measuring optical axis of the laser rangefinder can pass through the laser through hole without obstruction.

[0016] Preferably, the device is used to install on the steel-concrete tower body, which includes steel columns, concrete columns, and a transition plate disposed between the steel columns and the concrete columns. The core monitoring target of this device is the deformation state of the transition plate.

[0017] Preferably, to establish a measurement benchmark, the top plate serves as the measurement target point and is fixedly connected to the outer wall of the steel column; while the bottom plate serves as the installation foundation of the device and is fixedly connected to the outer wall of the concrete column.

[0018] Preferably, the gravity sensing disk is used to sense the gravity distribution of the mounting plate and output horizontal state data. The horizontal state data is the core reference signal for the automatic adjustment mechanism to adjust the attitude, and is used to precisely control the action of the rotating motor to ensure the accuracy of automatic calibration.

[0019] This invention solves the problem of low measurement accuracy caused by the difficulty in automatic calibration of existing monitoring devices by incorporating a laser rangefinder, a top plate, and an automatic adjustment mechanism consisting of a rotating motor, a rotating rod, a connecting rod, a universal joint, a mounting plate, and a gravity sensor. It achieves automatic posture adjustment, precise alignment, and high-precision real-time deformation monitoring. By using a rainproof shell to protect the internal rotating motor, rotating rod, connecting rod, and universal joint transmission components, and a protective shell to enclose the laser rangefinder, the invention addresses the issue of damage to internal components and precision instruments caused by rain, dust, and external impacts in outdoor environments, thus extending the device's lifespan. This improves the device's environmental adaptability, ensures long-term stable operation, and extends its service life. Furthermore, by incorporating a signal light electrically connected to the laser rangefinder, the invention solves the problems of unintuitive deformation data, the need for manual real-time reading, and the difficulty in timely detection of hazards. It automatically issues a visual warning signal when the deformation exceeds a preset threshold, prompting personnel to conduct timely maintenance and improving tower safety.

[0022] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0023] Reference Figures 1 to 4 This utility model provides a monitoring device for excessive deformation at the steel-concrete transition position of a steel-concrete tower, which aims to solve the problems of existing monitoring devices lacking automatic calibration capabilities, having imperfect protective structures, and being difficult to achieve high-precision real-time monitoring in outdoor environments.

[0024] like Figures 1 to 4 As shown, the excessive deformation monitoring device at the transition position of the steel-concrete tower is installed on the steel-concrete tower body. The steel-concrete tower body includes a steel column 3, a concrete column 4, and a transition plate 5 set between the steel column 3 and the concrete column 4. The transition plate 5 includes a top plate 1 fixedly connected to the outer wall of the steel column 3, and a bottom plate 6 fixedly connected to the outer wall of the concrete column 4. A rotating motor 8 is fixedly connected to the top of the bottom plate 6. One end of a rotating rod 9 is fixedly connected to the output end of the rotating motor 8. A connecting rod 10 is rotatably connected to the outer wall of the rotating rod 9. A universal joint 11 is fixedly connected to the top of the connecting rod 10. A mounting plate 12 is fixedly connected to the universal joint 10. At the top of plate 1, a gravity sensor 13 is located at the bottom of mounting plate 12. The gravity sensor 13 is used to sense the gravity distribution of mounting plate 12 and output horizontal state data. A protective shell 14 is fixedly connected to the top of mounting plate 12. A laser rangefinder 15 is fixedly connected inside the protective shell 14, and the measuring optical axis of the laser rangefinder 15 faces the top plate 1. A rainproof shell 7 is fixedly connected to the top outer wall of the bottom plate 6 and covers the outside of the rotating motor 8, rotating rod 9, connecting rod 10 and universal joint 11. A signal light 2 is fixedly installed on the top of the rainproof shell 7 and is electrically connected to the laser rangefinder 15.

[0025] Reference Figure 1 and Figure 4 The rotating motor 8 is fixedly connected to the top of the base plate 6, providing driving force for the entire adjustment mechanism. One end of the rotating rod 9 is fixedly connected to the output end of the rotating motor 8. The connecting rod 10 is rotatably connected to the outer wall of the rotating rod 9. The universal joint 11 is fixedly connected to the top of the connecting rod 10. The mounting plate 12 is fixedly connected to the top of the universal joint 11. The gravity sensing disk 13 is set at the bottom of the mounting plate 12.

[0026] Specifically, the gravity sensor 13 is used to sense the gravity distribution of the mounting plate 12 and output horizontal state data. The horizontal state data is used to control the start and stop of the rotating motor 8. After the rotating motor 8 starts, it drives the rotating rod 9 to rotate around the fixed axis. The rotating rod 9 transmits power to the universal joint 11 through the rotating connecting rod 10. The universal joint 11 changes the direction of force transmission, thereby driving the mounting plate 12 to adjust the angle.

[0027] To achieve measurement, a protective shell 14 is fixedly connected to the top of the mounting plate 12, and a laser rangefinder 15 is fixedly connected inside the protective shell 14. The protective shell 14 has a hollow structure, and the laser rangefinder 15 is housed in the hollow part of the protective shell 14. A laser through hole is opened on the top of the protective shell 14, and the measuring optical axis of the laser rangefinder 15 passes through the laser through hole and faces the top plate 1. This structure allows the laser rangefinder 15 to adjust synchronously when the mounting plate 12 is adjusted, thereby achieving precise alignment.

[0028] To clarify the installation environment of the device, please refer to... Figure 1 The device is used to install on the steel-concrete tower body, which includes a steel column 3, a concrete column 4, and a transition plate 5 disposed between the steel column 3 and the concrete column 4. More specifically, the top plate 1 is fixedly connected to the outer wall of the steel column 3, while the bottom plate 6 is fixedly connected to the outer wall of the concrete column 4. The laser rangefinder 15 monitors the deformation of the transition plate 5 by measuring the change in distance from itself to the top plate 1.

[0029] To protect the internal transmission components, please refer to... Figure 1 and Figure 3 It also includes a rainproof shell 7, which is fixedly connected to the top outer wall of the base plate 6. The rainproof shell 7 is a cover-type structure with a closed top and surrounding sides. The bottom edge is fixedly connected to the top surface of the base plate 6. The rainproof shell 7 and the base plate 6 together define a protective space for accommodating the rotating motor 8, the rotating rod 9, the connecting rod 10 and the universal joint 11, so as to isolate rainwater and dust.

[0030] To provide intuitive deformation warnings, please refer to... Figure 1 and Figure 3 It also includes a signal light 2, which is fixedly installed on the top of the rainproof housing 7 so that it can be observed. The signal light 2 is electrically connected to the laser rangefinder 15. When the distance change measured by the laser rangefinder 15 exceeds a preset threshold, the signal light 2 will light up to sound an alarm.

[0031] To protect the laser rangefinder 15 from external impacts, please refer to... Figure 2 The protective shell 14 has a hollow structure, and the laser rangefinder 15 is housed in the hollow part of the protective shell 14. A laser through hole is provided on the top of the protective shell 14, and the measuring optical axis of the laser rangefinder 15 passes through the laser through hole to ensure that distance measurement can still be performed in the protected state.

[0032] To provide reference data for the automatic adjustment mechanism, please refer to... Figure 4 The gravity sensor 13 is located at the bottom of the mounting plate 12. It is used to sense the gravity distribution of the mounting plate 12 and output horizontal state data. The horizontal state data is used to control the operation of the rotating motor 8, thereby driving the mounting plate 12 to adjust to a preset angle.

[0033] During initial installation and calibration, the base plate 6 of the device is fixedly connected to the outer wall of the concrete column 4, and the top plate 1 is fixedly connected to the outer wall of the steel column 3. The gravity sensing disk 13 is set at the bottom of the mounting plate 12. The gravity sensing disk 13 is used to sense the gravity distribution of the mounting plate 12 and output horizontal state data. The system determines whether the mounting plate 12 is at a preset angle based on the horizontal state data output by the gravity sensing disk 13. If it is not at the preset angle, the rotating motor 8 is started. The rotating motor 8 is fixedly connected to the top of the base plate 6, and the output end is fixedly connected to one end of the rotating rod 9. The rotating rod 9 rotates around the fixed axis and transmits power through the connecting rod 10 connected to the outer wall. The universal joint 11 fixedly connected to the top of the connecting rod 10 drives the mounting plate 12 to adjust the angle until the mounting plate 12 is adjusted to the preset angle, so that the laser rangefinder 15 inside the protective shell 14 fixedly connected to the top of the mounting plate 12 can accurately align with the top plate 1. During the monitoring process, the laser rangefinder 15 emits a laser through a laser through-hole on the top of the protective shell 14 and receives the signal reflected from the top plate 1, calculating the distance between itself and the top plate 1 in real time. The distance data is compared with the initial reference distance data to determine whether the transition plate 5 between the steel column 3 and the concrete column 4 has deformed. Throughout the process, the rainproof shell 7 is fixedly connected to the top outer wall of the base plate 6 and covers the outside of the rotating motor 8, the rotating rod 9, the connecting rod 10, and the universal joint 11. The rainproof shell 7 is a cover-type structure with a closed top and surrounding sides. The bottom edge is fixedly connected to the top surface of the base plate 6. The rainproof shell 7 and the base plate 6 together define a protective space for housing the rotating motor 8, achieving rain and dust protection. The hollow structure of the protective shell 14 houses the laser rangefinder 15, preventing it from being impacted by external forces. When the difference between the real-time distance data and the reference data exceeds the preset threshold, the signal light 2, which is electrically connected to the laser rangefinder 15, is powered on and illuminates. The signal light 2 is fixedly installed on the top of the rainproof shell 7 and issues a warning signal, indicating that the adapter plate 5 has undergone excessive deformation.
