The application relates to the technical field of starting motors, and particularly discloses a fan heat dissipation type starting motor for a centrifugal pump, which comprises a base and a machine shell fixedly connected to the base, a strip-shaped air inlet is arranged on the machine shell and penetrates through the inside and outside of the machine shell, a filter screen for shielding dust is arranged in the strip-shaped air inlet, a rotor is arranged in the machine shell, and a transmission shaft penetrates through the rotor coaxially. At the beginning of starting, the fan blade cannot rotate at high speed, so that the starting response slow degree and the starting current size of the centrifugal pump can be reduced, the additional energy consumption loss of the motor at the initial stage of starting can be reduced, the windward area of the fan blade at the initial stage of starting of the starting motor is small, so that the rotating resistance of the fan blade can be reduced, the starting response slow degree and the starting current size of the centrifugal pump can be further reduced, and the additional energy consumption loss of the motor at the initial stage of starting can be further reduced.

The invention provides a precision camera module with support adjustment, and relates to the technical field of cameras, the precision camera module comprises a camera body, the camera body is provided with a support mechanism convenient for supporting the camera body, and the support mechanism is provided with a windproof mechanism convenient for wind prevention. The support mechanism comprises a hinged base, a supporting frame and a mounting plate, the windproof mechanism comprises a supporting frame, a servo motor, a pulling plate, a solar panel and a C-shaped frame, the hinged base is located at the lower end of the camera body, and a top plate is fixedly mounted at the upper end of the supporting frame. Through cooperation of the wind power sensor, the servo motor, the pull plate, the powerful pull rope and the solar panel, in strong wind weather, the wind power sensor can automatically detect wind power and trigger the servo motor to work, the solar panel is driven to be stored in the embedded protection groove through the transmission structure, the windward side of the solar panel is effectively reduced, and the solar panel is prevented from being damaged. And the impact force of strong wind on equipment is reduced.

The invention relates to the technical field of unmanned aerial vehicles, and discloses a multi-rotor unmanned aerial vehicle with inclined vehicle arms, the multi-rotor unmanned aerial vehicle comprises a vehicle body and a plurality of rotors, the side wall of the vehicle body is rotatably connected with the plurality of vehicle arms, the number of the vehicle arms is equal to that of the rotors, the rotors are fixedly connected with the vehicle arms, and an adjusting mechanism is arranged in the vehicle body and used for adjusting the inclination angles of the vehicle arms. The inclination angles of the arms can be adjusted through the adjusting mechanisms, when the unmanned aerial vehicle flies forwards, the arms and the rotors are inclined through the adjusting mechanisms, the arms and the rotors are inclined forwards, forward inclination of the vehicle body and inclination of the rotors are replaced, the vertical component and the horizontal component of lift force can be changed, the pitch angle of the vehicle body is reduced, and therefore the inclination angle of the vehicle body is smaller; the windward side of the unmanned aerial vehicle body is smaller, so that the wind resistance of the unmanned aerial vehicle flying forwards is effectively reduced, the flying efficiency is improved, and the problems that the wind resistance is too large and the flying efficiency is reduced due to the too large windward side of the traditional unmanned aerial vehicle when the unmanned aerial vehicle advances are solved.
