The present application belongs to the technical field of inspection robots, and discloses an unlocking and door opening device, an unlocking and door opening method and an inspection robot. The unlocking and door opening device comprises a rack, a press-lock mechanism, a rotating mechanism and a door opening mechanism arranged on the rack. The press-lock mechanism can press the lock hole of a pop-up flat lock to make the rotating handle pop up. The rotating mechanism can operate the rotating handle to rotate to unlock. The door opening mechanism is used to pull the cabinet door to open the cabinet door. The unlocking and door opening device provided by the present application is used for unlocking and opening the cabinet door with a pop-up flat lock. When the rack is close to the cabinet door and faces the pop-up flat lock, the press-lock mechanism, the rotating mechanism and the door opening mechanism act in turn to realize a series of automatic control of pressing the lock to pop up the rotating handle, rotating the rotating handle to unlock and pulling the cabinet door to open the door. Thus, the remote control unlocking and door opening of the cabinet door with the pop-up flat lock are easily realized, and the execution efficiency is high, and the success rate of unlocking and door opening is high.

The embodiment of the invention provides an electric drive control system integrated with a vehicle-mounted charging function, a control method and a vehicle. The system comprises a first energy storage unit, a filtering unit, a first contact switch, a second contact switch, a third contact switch and an auxiliary bridge arm comprising three power semiconductor switches. When the three contact switches are all switched off, the first power semiconductor switch and the upper bridge arm are controlled to execute boost rectification conversion, the second power semiconductor switch is controlled to execute buck direct current conversion, and the vehicle-mounted charging function is achieved through single-stage topology. A second power semiconductor switch and a lower bridge arm are controlled to execute step-down conversion, a third power semiconductor switch is controlled to execute step-up direct current conversion, and the inversion output function of a battery is achieved through single-stage topology; according to the scheme, multiple functions of the electric drive control system are realized on the basis of improving the power density, so that the circuit cost is reduced.

The utility model relates to the technical field of agricultural machinery and engineering machinery, in particular to a novel air-assisted pesticide sprayer which comprises a caterpillar transport vehicle with a self-unloading function and a lifting platform, an air-assisted pesticide spraying mechanism is detachably mounted on the upper portion of the caterpillar transport vehicle and comprises a pesticide bin, and a control chamber is arranged on one side of the pesticide bin. A pesticide spraying pump and a pesticide spraying engine are arranged in the control chamber, an air blowing component is arranged on the other side of the control chamber, a pesticide outlet gap is formed between the inner end of the air blowing component and the outer end of the control chamber, the air blowing component comprises an air blowing ring, an air blowing fan is arranged in the air blowing ring and is in power connection with the pesticide spraying engine, and an adjusting edge is arranged on the air blowing ring. A rotatable pesticide spraying valve is installed on the adjusting edge, an adjusting pipe is arranged on the outer side of the adjusting long-strip hole, the adjusting pipe is fixedly installed on the adjusting edge through a positioning sleeve, the adjusting pipe is communicated with the pesticide spraying valve, and the adjusting pipe is communicated with the pesticide outlet end of the pesticide spraying pump through a liquid outlet pipe. The pesticide spraying valve can rotate to achieve fine adjustment of pesticide spraying of the pesticide spraying valve, and adjustment of the pesticide spraying angle of the pesticide spraying valve is achieved through adjustment of the adjusting pipe.
