[0001] The present invention relates to the technical field of building environment monitoring, and particularly relates to a building environment monitoring device and a using method thereof. Background Art
[0002] The building environment means that no building exists in isolation. It exists in various natural and man-made environments. The purpose of building a building is to provide an ideal place for people's social, economic, political, and cultural activities. During the construction process of a building, it is often necessary to monitor the environment to ensure the health and safety of workers or surrounding residents.
[0003] Currently, existing building environment monitoring devices are mostly divided into fixed structures buried in the ground and portable mobile structures. For the portable mobile building environment monitoring devices, since there are often moving wheels at the bottom of the device, and the height of the detection device is usually relatively high and is often installed outdoors, it is very easy to be affected by weather such as strong winds and cause the device to tilt, shake, and have poor stability, thus greatly affecting the safety of the device during use.

Conversely, the fixing seat 13 can also be disassembled from the fixed arm 12, thus facilitating disassembly, installation and maintenance, and greatly improving the use effect of the device.
[0049] A plurality of support plates 30 facing the fixed frame 2 are rotatably connected to the side wall of the base 1 through a rotating shaft. A movable movable block 29 is arranged inside each of the plurality of fixed frames 2. A support arm 31 is rotatably connected between the movable block 29 and the lower support plate 30 through a rotating shaft. A driving assembly is arranged between the base 1 and the fixed frame 2, and the driving assembly is used to drive the movable block 29 to slide inside the fixed frame 2.
[0050] A threaded rod 32 is rotatably connected to the inside of the fixed frame 2 through a bearing. The movable block 29 is screwed onto the outside of the threaded rod 32. The bottom ends of the plurality of threaded rods 32 all extend into the base 1 and are provided with gears 35.

The movable block 29 can drive the support arm 31 to move, so that the support arm 31 drives the support plate 30 to rotate on the base 1. Thus, a plurality of groups of support plates 30 can be simultaneously controlled to rotate outwards and unfold, so that the plurality of groups of support plates 30 are converted from a vertical storage state to a horizontal extension state. The support strengthening framework formed after horizontal extension can further limit and reinforce the device, thereby greatly enhancing the stability and safety of the device during environmental monitoring.

Under the meshing transmission of the toothed plate 20 and the gear 18, while the moving wheel 15 moves upward along the fixed seat 13, the other set of connecting posts 16 drives the U-shaped baffle 14 to descend along the fixed seat 13. Then, under the rebound of the spring 24, the positioning post 21 can be reset and inserted into the upper positioning hole 22, so that the moving wheel 15 and the U-shaped baffle 14 can be transposed and locked. At this time, the moving wheel 15 leaves the ground, and multiple U-shaped baffles 14 support on the ground, thereby making the device stable;
