Description

Technical Field

[0001] This utility model relates to the field of hanging basket safety monitoring technology, specifically to a safety monitoring device for hanging baskets. Background Technology

[0002] In the construction of large-scale buildings such as bridges, the hanging basket is a critical piece of construction equipment, and its safety is directly related to the project progress and the safety of personnel. Traditional hanging basket safety monitoring mainly relies on regular manual inspections and experience-based judgment, which has shortcomings such as low monitoring frequency, strong data lag, and large human error. It is difficult to capture potential risks such as sudden changes in structural stress and abnormal displacement in real time. Especially in complex construction environments, factors such as strong winds and equipment tilting may cause the hanging basket to become unstable, and traditional monitoring methods cannot detect changes in environmental parameters in a timely manner and trigger early warnings.

[0003] While some automated monitoring devices exist in existing technologies, they mostly employ a single sensor type, resulting in insufficient monitoring dimensions. For example, they may focus only on stress or displacement while ignoring the coupling effects of environmental factors. Furthermore, data transmission relies on wired connections, leading to complex wiring, difficult maintenance, and other problems, making it difficult to adapt to the mobility requirements of high-altitude operations. In addition, alarm mechanisms are generally limited to on-site audio-visual prompts, failing to provide operators with immediate tactile feedback, which can easily cause missed warnings in noisy construction environments. Utility Model Content

[0011] As a further embodiment of this utility model: the vibrating wire stress sensor of the stress monitoring module is fixed to the welded base of the main truss of the hanging basket by bolts.

The base is made of Q345 steel with a thickness of 10mm. After welding, ultrasonic flaw detection is performed to ensure that there are no defects. A silicone shock-absorbing pad is placed between the sensor and the base to reduce vibration interference.

[0012] As a further embodiment of this utility model: the laser displacement sensor of the displacement monitoring module is installed on the end of the hanging basket crossbeam via an adjustable bracket. The bracket includes a U-shaped clamp and a rotating joint. The clamp is fixed to the crossbeam, and the rotating joint allows the sensor to adjust its angle within a range of ±30° in the horizontal direction. The clamp is lined with a rubber anti-slip pad and is fastened with M12 bolts. The rotating joint adopts a damping design to ensure that the sensor does not shift due to vibration after the angle is fixed.

[0013] As a further embodiment of this utility model: the audible and visual alarm of the alarm module is a combination of LED flashing lights and buzzers, installed around the hanging basket operating platform.

When the stress or displacement exceeds the limit, the audible and visual alarm will be activated immediately; if no confirmation is received within 5 seconds, the vibration motor will be triggered and will automatically stop after 10 seconds.

[0014] As a further embodiment of this utility model: the solar panel of the power module is made of monocrystalline silicon material with a power of 100W. It is installed at an angle on the side of the hanging basket, and the angle can be manually adjusted to adapt to different latitude regions. It adopts an MPPT solar charging controller with a maximum charging current of 5A and has overcharge, over-discharge, and short circuit protection functions.

[0015] Compared with existing technologies, the advantages of this utility model are as follows: In stress monitoring, the vibrating wire stress sensor is bolted to the L-shaped steel plate base welded to the main truss, ensuring stable installation and accurate real-time acquisition of stress data from key areas. For displacement monitoring, the laser displacement sensor is mounted on an adjustable bracket, and its angle can be adjusted ±30° horizontally via a U-shaped clamp and a rotating joint, flexibly measuring lateral displacement. The alarm module uses a combination of LED strobe lights and a buzzer, mounted around the operating platform. The vibration motor is a miniature eccentric wheel motor, fixed to one side of the safety helmet and wirelessly connected via Bluetooth, achieving dual-mode audible and visual / vibration alarms to avoid missed warnings in noisy environments.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0025] Combined with appendix Figure 1-4The process involves several steps: First, the overall device is installed, with each module positioned according to the design requirements and the connections ensured to be stable, reliable, and functional. For the stress monitoring module, a 10mm thick Q345 steel L-shaped steel plate base is constructed, with one end welded to the main truss surface of the hanging basket. After welding, ultrasonic testing is used to ensure no defects. A vibrating wire stress sensor 1 is bolted to the threaded hole at the other end of the base, and a silicone damping pad is placed between the sensor and the base to reduce vibration interference. The sensor is installed at key stress-bearing points of the main truss to collect stress data in real time. For the displacement monitoring module, a U-shaped clamp with an inner rubber anti-slip pad is first fitted onto the hanging basket beam and secured with M12 bolts. Then, the laser displacement sensor 2 is installed using an adjustable bracket. The damping design on the bracket allows for adjustment of the sensor angle within a ±30° horizontal range using a rotating joint, ensuring that the sensor does not shift due to vibration after fixing, allowing the laser to accurately emit towards a fixed reference point to measure lateral displacement. For the environmental monitoring module, a wind speed sensor 3 is installed on the top of the hanging basket, and an inclination sensor 4 is installed on... At the bottom of the hanging basket, accurate monitoring of wind speed and tilt angle is ensured. During the implementation of the data processing and transmission module, the microcontroller and wireless communication unit are connected, and electrically connected to the stress, displacement, and environmental monitoring modules. Each monitoring module transmits the collected data to the microcontroller, which processes and analyzes it before uploading it to the cloud server via a 4G / 5G network. During the implementation of the alarm module, an audible and visual alarm consisting of an LED strobe light and a buzzer is installed around the hanging basket's operating platform. A miniature eccentric wheel motor (5) is fixed to the outside of the operator's safety helmet and wirelessly connected to the microcontroller via Bluetooth. When stress or displacement exceeds limits, the audible and visual alarm immediately activates. If no confirmation is received within 5 seconds, the vibration motor is triggered and automatically stops after 10 seconds. During the implementation of the power module, a 100W monocrystalline silicon solar panel (6) is installed at an angle on the side of the hanging basket and its angle can be manually adjusted. An MPPT solar charge controller manages the power, with a maximum charging current of 5A and overcharge, over-discharge, and short-circuit protection functions. A lithium battery pack provides backup power to ensure continuous operation when solar energy is insufficient.

[0026] The working principle of this utility model is as follows: First, the vibrating wire stress sensor 1 of the stress monitoring module is installed at the key stress-bearing parts of the main truss of the hanging basket. When the main truss is deformed under stress, the vibrating wire inside the sensor will change its vibration frequency due to the stress change. By measuring this frequency change and based on the pre-calibrated stress-frequency relationship, the stress data of the main truss can be collected in real time and accurately. The laser displacement sensor 2 of the displacement monitoring module is fixed to the end of the hanging basket beam via an adjustable bracket. It emits a laser towards a fixed reference point. The laser is reflected back from the reference point. The sensor calculates the distance to the reference point by measuring the time difference between laser emission and reception and combining it with the speed of light. This distance changes when the hanging basket moves laterally, thereby measuring the lateral displacement data. In the environmental monitoring module, the wind speed sensor 3 is installed at the top of the hanging basket. It uses the effect of wind on the sensitive element inside the sensor to generate a corresponding electrical signal. The wind speed data is obtained based on the magnitude of the electrical signal and the pre-set wind speed-electrical signal relationship. The tilt sensor 4 is installed at the bottom of the hanging basket. It senses the change in the tilt angle of the hanging basket through internal gyroscopes or accelerometers and outputs the corresponding angle data. The data processing and transmission module... The microcontroller receives data such as stress, displacement, wind speed, and tilt angle, and processes it through filtering, amplification, and analog-to-digital conversion to remove noise interference and convert it into digital signals. It then performs comprehensive analysis and judgment based on a preset algorithm. If the data is normal, it is stored. The processed data is then uploaded to a cloud server via a 4G / 5G network through a wireless communication unit for remote monitoring. When the microcontroller detects that stress or displacement data exceeds a preset threshold, it immediately sends a command to the alarm module. The LED strobe light of the audible and visual alarm flashes, and the buzzer sounds an alarm. If the operator does not confirm within 5 seconds, the microcontroller sends a signal to the vibration motor 5, activating the miniature eccentric wheel motor. Fixed to one side of the safety helmet, the motor vibrates to alert the operator, automatically stopping after 10 seconds. In the power module, the solar panel 6 converts solar energy into electrical energy when there is sunlight. Managed by the MPPT solar charging controller, it charges the lithium battery pack with a maximum charging current of 5A. The controller also has overcharge, over-discharge, and short-circuit protection functions. When solar energy is insufficient, the lithium battery pack powers all modules, ensuring continuous and stable operation of the device.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
