Description

TECHNICAL FIELD

[0001] The utility model belongs to structural safety monitoring equipment technical field, specifically is a building / building wind snow load monitoring equipment. BACKGROUND

[0002] With global climate change, extreme weather phenomena such as wind and snow are increasingly frequent, posing a serious threat to the safety of buildings / buildings. According to reports, every year a large number of gas station canopies, gymnasium roofs, crop greenhouses and other structures collapse due to excessive wind and snow loads, resulting in serious economic losses and casualties. Even in the southern provinces, cases of buildings / buildings collapsing due to exceeding the design load limit have occurred repeatedly in extreme weather conditions of rain, snow and freezing. Such building safety hazards require more scientific and effective monitoring methods, therefore, real-time monitoring of wind and snow loads on buildings / buildings and timely warning have become key technical requirements to ensure structural safety.

[0003] Some of the existing devices on the market for monitoring the wind and snow loads on buildings are mostly single-function, lacking comprehensive monitoring and warning capabilities.

However, it cannot reflect the comprehensive impact of wind and snow coupling on the structure, resulting in one-sided load evaluation, and it cannot provide differentiated multi-level alarm prompts according to risk levels.

[0028] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0029] Example 1: As Figs. 1-2 As shown, this application proposes a building / structure wind and snow load monitoring device, including a main unit 1.

[0031] The temperature and humidity sensor 6, the wind speed sensor 7 and the displacement sensor 8 are installed on the building / structure to be monitored; the ultrasonic ranging sensor 10 is installed at the top end of the telescopic range finder installation stand 17, the telescopic range finder installation stand 17 includes a sleeve 18 and a screw rod 19, the screw rod 19 is threadedly connected in the sleeve 18, the ultrasonic ranging sensor 10 is installed at the top end of the screw rod 19, the sleeve 18 is detachably installed on the upper surface of the load test tray 2, the lower surface of the load test tray 2 is installed on the top end of the load monitoring component support rod 4 through the load monitoring sensor 3, the bottom end of the load monitoring component support rod 4 is fixedly installed on the load monitoring component base 5, and the load monitoring component base 5 is used to install the load monitoring component composed of the load test tray 2, the load monitoring sensor 3, the load monitoring component support rod 4 and the load monitoring component base 5 as a whole on the building / structure to be monitored, or on other nearby buildings / structures in the same environment as the building / structure to be monitored.

[0032] The load monitoring sensor 3 is a pressure type load sensor.

[0033] It should be noted that the load monitoring sensor 3 will be calibrated after installation, and the static weight of the load test tray 2, the telescopic range finder installation stand 17 and the ultrasonic ranging sensor 10 will be automatically deducted, and only the dynamically increased snow load will be measured. The load monitoring sensor 3 adopts the strain gauge principle, and the output signal only responds to the change of the newly added pressure. The static pre-pressing is eliminated by circuit zero adjustment, and does not affect the dynamic measurement accuracy. Therefore, the weight of the load test tray 2, the telescopic range finder installation stand 17 and the ultrasonic ranging sensor 10 does not affect the monitoring data accuracy of the load monitoring sensor 3.

[0034] In specific use, the temperature and humidity sensor 6, the wind speed sensor 7, and the displacement sensor 8 are installed on the building / structure to be monitored, the values measured by the sensors related to the building / structure to be monitored are collected and transmitted to the control mainboard 14, the load monitoring component base 5 is installed on the building / structure to be monitored or other nearby buildings / structures in the same environment as the building / structure to be monitored, the load monitoring sensor 3 monitors the wind load and snow load data in real time and transmits them to the control mainboard 14, and the ultrasonic ranging sensor 10 measures the snow height on the load test tray 2 and transmits it to the control mainboard 14 to provide reference data for monitoring the snowfall.

The control mainboard 14 receives, analyzes, processes, displays, stores, and uploads the data of the temperature and humidity sensor 6, the wind speed sensor 7, the displacement sensor 8, the load monitoring sensor 3, and the ultrasonic ranging sensor 10 in real time, and provides multi-level early warning prompts through the sound alarm module 16, the audible and visual alarm 21, and the indicator light 20 according to the threshold parameters set in advance.

[0035] For example: Level 1 warning (low risk): a single parameter (such as snow thickness) approaches the threshold value, triggering the indicator light 20 to flash yellow to prompt attention.

[0036] Level 2 warning (medium risk): multiple parameters (such as snow pressure + wind speed) exceed the limit, triggering the sound alarm module 16 to intermittently beep and the indicator light 20 to flash red.

[0037] Level 3 warning (high risk): significant displacement or load reaching the critical value, starting the audible and visual alarm for continuous alarm + strong light flashing, prompting emergency disposal.

[0038] The above examples are only for the convenience of understanding the present application and are not the only alarm prompt method. The sound alarm module, the indicator light, and the audible and visual alarm can be set to independently or combinedly issue alarm prompt signals as needed.

[0039] Based on the above settings, the device can monitor the wind load, snow load, displacement change, and other information of the building / structure in real time.
