The invention relates to the technical field of radars, and discloses an active ventilation cooling system and method for a radar radome, the system comprises a top ventilation opening, the radome, an active ventilation cooling device and a fan controller, the top ventilation opening is located at the top end of the radome and is used for natural ventilation and auxiliary heat dissipation; the antenna housing is designed to be in a cavity opening type hemisphere shape so as to adapt to installation and operation of a radar antenna. The active ventilation cooling device is arranged at the bottom end of the antenna housing and is used for air intake and air exhaust; and the fan controller is used for controlling the start and stop of the active ventilation cooling device. The problem of poor heat dissipation of the radar radome in a high-temperature environment can be solved, and efficient heat dissipation, automatic control and all-weather work are realized.

This utility model relates to a medical pendant with self-lubricating function, belonging to the field of medical device technology. It solves the problem of inadequate lubrication caused by bearings detaching from lubricating oil during operation in existing medical pendants. This utility model includes a drive mechanism, which comprises a shaft and an oil reservoir ring. An oil inlet hole is provided along the axial direction of the shaft, penetrating at least one end of the shaft. An oil distribution hole is provided along the radial direction of the shaft, communicating with the oil inlet hole. The oil reservoir ring is located at the end of the oil inlet hole near the lubricating oil. A height difference exists between the inner wall of the oil reservoir ring at the end furthest from the shaft and the inner wall of the oil inlet hole, forming an oil reservoir. After the shaft detaches from the lubricating oil, under the action of centrifugal force, the lubricating oil in the oil reservoir flows out through the oil distribution hole and lubricates the rolling bearings mounted on the shaft, achieving uninterrupted continuous lubrication of the rolling bearings and ensuring smooth reciprocating lifting and lowering of the medical pendant's cantilever.

The application relates to the field of radar technology and discloses an active ventilation cooling system and method for a radar antenna cover, which comprises a top ventilation opening, an antenna cover, an active ventilation cooling device and a fan controller, the top ventilation opening is located at the top end of the antenna cover and is used for natural ventilation and auxiliary heat dissipation, the antenna cover is designed as a cavity opening type semispherical shape to adapt to the installation and operation of a radar antenna, the active ventilation cooling device is arranged at the bottom end of the antenna cover and is used for air intake and air exhaust, and the fan controller is used for controlling the start and stop of the active ventilation cooling device. The active ventilation cooling system and method can solve the problem of poor heat dissipation of the radar antenna cover in a high-temperature environment, realize efficient heat dissipation, automatic control and all-weather operation.

The invention provides a fault detection system and method for the operation condition of a yaw transmission system of a wind driven generator. The fault detection system comprises a system control module, a torque detection module, a temperature detection module and an early warning module. The torque detection module is used for detecting the torque magnitude and direction of the output main shaft and each input shaft of the yaw transmission system; the temperature detection module is used for detecting the temperature of each driving motor of the yaw transmission system and the environment temperature in a cabin of the wind driven generator; the system control module performs information interaction with the torque detection module, the temperature detection module and the early warning module, and is used for processing torque and temperature information collected by the torque detection module and the temperature detection module, judging whether an abnormal condition exists or not and obtaining a performance index value; and the working state of the yaw transmission system is detected according to the fault data model, and a processing result is transmitted to the early warning module to be output.

The utility model discloses agricultural anti-splashing mowing equipment, which relates to the technical field of mowing equipment and comprises a mowing trolley, a controller, a suction unit and a lifting unit are mounted on the mowing trolley, a storage battery and a collecting tank are mounted in the mowing trolley, a collecting box is mounted in the collecting tank, a mounting frame is mounted on the lifting unit, and the storage battery is mounted on the mounting frame. And a mowing unit and a protection unit are mounted on the mounting frame. The device has the beneficial effects that the protective cover is supported and buffered through the damping rod and the spring, the impact force of splattering of smashed grass during mowing on the protective cover is effectively reduced, the service life of the protective cover is prolonged, sundries such as the smashed grass adhering to the interior of the protective cover fall off through cooperation of the damping rod, the spring and the scraping plate, adhesion and accumulation of the smashed grass in the protective cover are reduced, and the service life of the protective cover is prolonged. Crushed grass can be conveniently drawn out, and normal work of equipment is guaranteed.
