The utility model discloses a drill bit transportation protection device for petroleum drilling, and relates to the technical field of drill bits, the drill bit transportation protection device comprises a protection box, the bottom of the inner wall of the protection box is fixedly connected with a bearing base, the top end of the protection box is movably connected with a box cover in an inserted mode, the inner wall of the protection box is provided with a clamping assembly, and the clamping assembly comprises a vertical guide rail. The inner wall of the vertical guide rail is slidably connected with a vertical sliding block. Through the linkage design of the box cover and the lower pressing rod, automatic triggering of the clamping assembly is achieved. When the box cover is closed, the clamping arc plates can be driven to synchronously move and rapidly clamp the drill bit without additional operation, the clamping force is automatically adjusted along with the closing degree of the box cover, the device adapts to drill bits of different sizes, the universality of the device is improved, the arc block springs and the pressure-bearing springs provide vertical and transverse buffering effects correspondingly, and a three-dimensional buffering system is formed. In the transportation process, vibration energy generated by road bumping, collision and the like can be effectively absorbed.

The application relates to the technical field of unmanned planes, in particular to a hydrogen fuel cell unmanned plane with an emergency function for sea deployment, which comprises a lower part of an unmanned plane body provided with supporting legs; the hydrogen fuel cell unmanned plane further comprises: containing bins which are symmetrically arranged on the two sides of the lower part of the unmanned plane body in pairs and relative to the supporting legs, the two containing bins are located on the outer sides of the supporting legs, hydrogen gas cylinder bodies are arranged in the containing bins, and the lower ends of the supporting legs are lower than the lower ends of the containing bins; pushing mechanisms which are connected with the two containing bins in pairs; and a driving source arranged between the two pushing mechanisms, the driving source is used for driving the two pushing mechanisms to synchronously push the two containing bins to move away from each other. The application improves the floating stability of the unmanned plane on the sea surface, and avoids the unmanned plane from being overturned due to swinging with sea waves.
