Description

Technical Field

[0001] The present application relates to the technical field of detecting displacement of urban elevated bridges, and more specifically, to a multi-point early warning radar displacement detection device for urban elevated bridges. Background Art

[0002] As an important part of urban transportation, urban viaducts carry a large number of vehicles and pedestrians. However, due to natural factors, vehicle vibration and long-term use, the structure of the viaduct may be displaced. If the displacement of the bridge exceeds a certain range, it may cause the damage or even collapse of the bridge, posing a serious threat to people's lives and property safety. Therefore, real-time monitoring and early warning of the displacement of the viaduct is of great significance.

[0003] In view of the above-mentioned related technologies, the inventor believes that the current monitoring of elevated bridge displacement mainly adopts traditional measurement methods, such as total station, GPS and laser rangefinder. However, these traditional measurement methods have the problems of low measurement accuracy, long monitoring cycle and high labor cost. At the same time, the existing devices are directly installed on the elevated bridge, which is troublesome to install, with cumbersome steps, and difficult to disassemble after installation. It is time-consuming and laborious for staff to check and replace them regularly.

[0004] In view of this, we propose a multi-point early warning radar displacement detection device for urban elevated bridges. Utility Model Content

[0005] The purpose of this application is to provide a multi-point early warning radar displacement detection device for urban elevated bridges, solve the technical problems in the above-mentioned background technology, and achieve the technical effect of a multi-point early warning radar displacement detection device for urban elevated bridges.

[0007] By adopting the above technical solution, the staff uses multiple early warning radar displacement detection devices. The radar sensor in the early warning radar displacement detection equipment can determine the displacement of the bridge by measuring the echo information of the electromagnetic wave. The radar sensor has high accuracy and plays a good detection role. The distribution of multiple radar sensors can simultaneously monitor the displacement of multiple key points of the elevated bridge, thereby improving the accuracy and reliability of monitoring.

[0009] By adopting the above technical solution, during installation, the first limit block and the second limit block on the extension rod are inserted into the slot on the fixed frame, and when the second limit block contacts the bottom of the slot, the spring contracts. When the first limit block is located at the first slide groove, the sealing box and the fixed frame are rotated, and the first limit block and the second limit block slide inside the first slide groove and the second slide groove respectively, and the second limit block moves into the limit groove, the spring rebounds, and the second limit block rests on the bottom of the limit groove, thereby achieving the limiting effect. At the same time, the spring plays a good supporting role, making the installation of the sealing box and the fixed frame more stable, simple to install, and convenient for later replacement by staff, which greatly improves the use effect of the device.

[0010] Optionally, a silicone sheet is adhered to the upper end surface of the mounting plate, and the second limiting block is located below the first limiting block.

[0011] By adopting the above technical solution, the silicone sheet plays a good anti-slip role, so that the installation plate can fit tightly with the bridge deck, and the later installation is more secure.

[0012] Optionally, the upper end of the radar sensor passes through the sealing plate, the lower end surface of the connecting plate is fixedly connected with a data processing unit, a data transmission module and an early warning signal module, and one end of the early warning signal module extends out of the sealing box.

[0013] By adopting the above technical solution, the data processing unit is used to receive and process the displacement data from the radar sensor. The data processing unit filters, corrects and analyzes the displacement data to obtain the actual displacement of the elevated bridge. The data processing unit can also compare the displacement data with a preset displacement threshold to determine whether the displacement exceeds the preset threshold. The data transmission module will transmit the data to the early warning system. The early warning system is used to monitor the data of each radar sensor. The early warning system sends a warning signal according to the analysis results of the data processing unit. The early warning system can use SMS alarms or remote monitoring to inform the staff. When the displacement of the elevated bridge exceeds the preset threshold, the early warning system will promptly send an alarm message to the relevant departments so that corresponding measures can be taken. At the same time, the indicator light on the early warning signal module flashes, which is convenient for the staff to quickly know the specific location of the accident.
