2results about How to "Solve miniaturization" patented technology

This invention provides a static cone penetration test (CPPT) system and method for measuring the thickness of carnallite ore layers based on an unmanned surface vessel (USV) with variable buoyancy anchoring. The system includes an USV body, a penetration unit, a main control unit, a data acquisition unit, a multi-parameter formation identification unit, and a fluid counterweight anchoring unit. When the USV body is not performing detection operations, the fluid counterweight anchoring unit increases the weight of the hull. As the static cone penetration probe penetrates the formation, it collects the end resistance at the probe tip and the frictional force on the probe sidewall sleeve, transmitting these data to the multi-parameter formation identification unit. The identification unit identifies the upper and lower interfaces of the carnallite ore layer. The control unit calculates the carnallite ore thickness based on the depth difference between the static cone penetration probes at the upper and lower interfaces of the carnallite ore layer. This invention improves measurement accuracy, resolves the contradiction between miniaturization and large reaction forces, does not damage the original crystallization environment of the salt lake, and enhances the safety of unmanned operations.

The application discloses an electric appliance door lock and an electric appliance, and relates to the technical field of door locks, wherein the electric appliance door lock comprises a shell with a cam, the cam locks a door hook by turning over; the electric appliance box is provided with a peach heart sliding block and a power-off top rod, the peach heart sliding block is provided with a stop portion, and the power-off top rod is provided with an actuating portion; when the door hook is inserted into a lock hole, a driving push block is driven to move, when the push block moves, a power-off block is driven to move, the power-off block is matched with the actuating portion of the power-off top rod, and an included angle is formed between the extension direction of the power-off block and the extension direction of the push block; the locking block is provided with a blocking portion, the blocking portion blocks the movement path of the stop portion of the peach heart sliding block, and an included angle is formed between the extension direction of the locking block and the extension direction of the power-off block. According to the technical scheme, the push block, the power-off block and the locking block are sequentially and bently connected in the shell, the space occupied by a single sliding member before the improvement is reduced, and the shell is facilitated to realize miniaturization.
