Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel measurement, in particular to a wind temperature and wind speed monitoring device in a tunnel. Background Art

[0002] Tunnel projects generally require a long construction process, especially when the tunnel passes through mountainous areas. During the construction process, it may be affected by various natural factors such as temperature and air humidity. Therefore, it is very important to control the temperature in the tunnel. Due to the different locations of the tunnel, it will be affected by various weather conditions. Generally, the temperature in the tunnel will change with the changes in weather conditions. The temperature difference between the entrance and exit of the tunnel will also cause air flow inside the tunnel. After searching, the patent with application number 202123408983.7 discloses a wind temperature and wind speed monitoring device in a cold-region high-speed railway tunnel, including: six brackets for installation on the lining surface of the left and right arch waists, left and right walls and left and right arch feet of the tunnel section to be measured; it is a cube-shaped frame structure, and the frame encloses a cavity connected to the outside world so that the wind flow enters the cavity and passes through in the original direction of travel; wind direction and wind speed sensors are located in the cavity of each bracket one by one, and are used to be installed on the lining surface; wind temperature sensors are located in the cavity of each bracket one by one, and are used to be installed on the lining surface; mounting blocks are installed in the side ditches at the left and right arch feet of the tunnel section to be measured, and each mounting block is connected to each wind direction and wind speed sensor and wind temperature sensor located on the same side.

[0003] However, during actual use, the applicant found that the wind direction and wind speed sensors and wind temperature sensors on its monitoring device were fixedly connected to the bracket, and the bracket was fixed to the inner wall of the tunnel by multiple bolts. When maintaining the wind direction and wind speed sensors and wind temperature sensors, personnel are required to remove and install the bolts one by one, which is not convenient to operate. In view of this, we propose a wind temperature and wind speed monitoring device for tunnels. Utility Model Content
