This application provides an auxiliary positioning device, relating to the field of equipment positioning technology, to solve the technical problem of low positioning efficiency in current equipment positioning methods. The auxiliary positioning device includes a positioning bracket, a line marker, and a rangefinder; the line marker is adapted to emit a positioning cursor with the same shape as the target mark; the rangefinder is adapted to emit a ranging light beam, and when the rangefinder is in measurement mode, the emission direction of the ranging light beam is perpendicular to the mounting plane. The auxiliary positioning device provided in this application uses the line marker to emit a positioning cursor towards the mounting plane. When the positioning cursor coincides with the target mark, the positioning bracket is positioned, and the equipment moves below the line marker. The positioning cursor assists in adjusting the equipment position until the positioning cursor coincides with the loading mark. The rangefinder emits a ranging light beam, and the line marker assists in adjusting the height of the equipment until the distance between the rangefinder and the first surface reaches a preset value, completing the equipment height adjustment. The operation is convenient.

The utility model discloses a construction quality acceptance measuring instrument, which comprises a shell, a display screen arranged on the surface of the shell, and keys arranged below the display screen, the side frame assembly comprises bottom protruding blocks symmetrically fixed to the two sides of the bottom end of the shell, connecting grooves formed in the bottom protruding blocks, and side frames with the bottom ends rotationally connected into the connecting grooves.

The "Disc Drone" invention relates to vertical takeoff and landing (VTOL) unmanned aerial vehicles. The disc drone provides the user with real-time tactical and reconnaissance information by transmitting video images to the operator's control panel from a dedicated camera mounted on the UAV. The invention is made according to a “Flying Saucer” type design, comprising a body (3) with a camera for all-round viewing on top (1) and a compartment for cargo and equipment (5) at the bottom, inside the body, on the outer ring, two electric motors (6) are installed, which set in motion two ring-shaped rotors with blades (7), thereby creating an air flow directed to the lower part of the drone, and providing lifting force. An external protective casing (4) surrounds the rotor blades, protecting them from external physical impact and mechanical damage. The external protective casing contains a system of opening flaps (2) that redirect part of the airflow generated by the blades in the desired direction, thereby enabling horizontal flight. The payload can include a video camera, laser rangefinder, repeater, additional radio equipment, thermal imager, gas analyzer, and various types of ammunition. The control system and battery are housed in a dedicated compartment inside the hull, above the cargo and additional equipment compartment. The technical result of the "Disc Drone" invention is achieved through a completely new flight principle and layout, previously unused in unmanned aerial vehicle (UAV) development. These principles are designed to provide the drone with greater wind resistance and protect the blades and payload from mechanical damage. The body is disk-shaped, housing two synchronous electric motors. Two ring-shaped rotors with blades are mounted around the body. An external protective hull with a system of shutters is installed around them, attached to the main hull, preventing the rotors from falling out and separating from the hull. A 360-degree camera on top of the hull provides tactical and visual information. The control system and battery are located in a compartment inside the hull above the cargo hold. Upon command from the control panel, the payload can be released for delivery or, if munitions are used, to destroy the target. Flight altitude is controlled by varying the rotor speed. Horizontal flight speed and direction, as well as stabilization of the drone in the air, are controlled by opening the outer hull doors to a specific value.
