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 invention belongs to the technical field of book management, and discloses an automatic book scanner based on book management, which comprises a bottom plate, a scanning device and a scanning detection system are arranged at the top of the bottom plate, and a cleaning device is arranged at the top of the bottom plate and positioned on one side of the scanning device. Multi-dimensional accurate movement of the scanner is achieved through double-screw driving, the scanner adapts to different bookshelf layouts and book positions, the scanning range and flexibility are improved, it is ensured that book information is efficiently obtained, the light supplementing lamp and the light gathering cover are matched with the camera, book images can be clearly collected even if light is poor, the image quality is improved, and subsequent accurate book recognition is facilitated; all modules of the scanning detection system cooperate, automatic detection, judgment, control and reminding are achieved, manual errors are reduced, the book management efficiency and informatization level are improved, ordered placement and accurate management of books are guaranteed, the collision avoiding module effectively avoids collision damage of equipment and bookshelves, the service life of the equipment is prolonged, and safe and stable operation is guaranteed. And practical application and operation are facilitated.

The embodiment of the present application provides a scanner. The scanner comprises a battery, a microcontroller, a photosensitive sensor connected with the battery and outputting an intensity signal representing the intensity of ambient light in the environment where the scanner is located, and a power supply circuit connected with the battery, the photosensitive sensor and the microcontroller respectively, wherein the power supply circuit comprises a designated switch unit, and the power supply circuit supplies power to the microcontroller by using the power of the battery when the received intensity signal triggers the designated switch unit to be turned on; and wherein the microcontroller controls the scanner to enter a start-up state when the microcontroller determines that a start-up condition is met. The use convenience of the scanner can be improved to a certain extent.

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.
