The utility model discloses a hydrogen evacuating and desorbing device, which relates to the technical field of hydrogen evacuating and desorbing, and comprises a box body and a cover plate, the top of the box body is movably connected with the cover plate, the cover plate is internally provided with a through hole, the inside of the through hole is fixedly connected with a sealing ring, and the top of the cover plate is fixedly connected with an anti-backfire mechanism. Sealing silica gel is fixedly connected into the cover plate, the two sets of penetrating holes are symmetrically distributed, the outer diameter of the sealing ring is consistent with that of the sealing pipe, and the sealing ring prevents oxygen from entering the box body. Compared with an existing common hydrogen evacuating and desorbing device, the hydrogen evacuating and desorbing device has the advantages that hydrogen and oxygen are conveyed to different desorbing bottles through different sealing pipes and then output through the output pipe, reaction between the hydrogen and the oxygen is avoided, the device is simple in structure, workers cannot operate the device in dangerous places, accidents are prevented from occurring and spreading, and the device is suitable for popularization and application. The density of the sealing ring is large, gas leakage is avoided, and the sealing performance of oxygen and hydrogen in the transportation process is guaranteed.

This application relates to a concrete pouring temperature and humidity measuring device, belonging to the technical field of building construction monitoring. It includes a cover, with an outer shell fixedly connected to its bottom. Two connecting members are fixedly connected to the bottom of the outer shell. A shielding mechanism is fixedly connected to adjacent sides of the two connecting members. The shielding mechanism includes a retrieval component, with both its left and right sides fixedly connected to adjacent sides of the two connecting members. A fixing plate is fixedly connected to the rear side of the retrieval component. Two electric push blocks are slidably connected to the rear side of the fixing plate. A rotating plate is rotatably connected to the rear side of each of the two electric push blocks. A connecting rod is rotatably connected to the front side of each of the two rotating plates. This application allows the electric push blocks to move, causing the rotating plates to rotate. The connecting rod at the bottom of the rotating plates causes the moving block to move within the fixing plate, resulting in the shielding cloth moving downwards, thus achieving the effect of isolating external factors during measurement.
