The invention discloses a water and soil conservation remote monitoring system and a detection method thereof. The system comprises a protection box, a solar mechanism, a supporting mechanism and a PLC. The top end of the protection box is connected with a sun mechanism; the side surface of the protection box is connected with a liquid storage mechanism; a supporting mechanism is arranged at the bottom end of the protection box; the bottom end of the supporting mechanism is connected with a treatment barrel; the top end of the treatment barrel is connected with a barrel cover through a plurality of groups of countersunk bolts; the top end of the barrel cover is connected with a processing mechanism; a sediment treatment sensor is bonded to the inner wall of a water inlet dug in the side face of the treatment barrel, a fixing frame is further bonded to the inner wall of the treatment barrel, a filter screen is bonded to the top end of the fixing frame, a water outlet mechanism is connected to the side face of the treatment barrel, and two balance weight mechanisms are further connected to the side face of the treatment barrel. According to the water and soil conservation remote monitoring system and the detection method thereof, real-time monitoring and control can be carried out, and the overall stability is high.

The invention provides a rotary drilling machine with an automatic counterweight device in order to solve the problem that a counterweight mechanism cannot conduct weight counterbalance in time. The rotary drilling machine comprises a travelling mechanism, a manipulating mechanism, a drilling bucket mechanism and a mooring rope and further comprises a counterweight mechanism, the drilling bucket mechanism is connected with the counterweight mechanism through the mooring rope, and the counterweight mechanism comprises a sliding table and a counterweight box slidably arranged with the sliding table and further comprises a first pulley, a second pulley and a third pulley, wherein the first pulley and the second pulley are arranged at the front end and the rear end of the sliding table correspondingly, and the third pulley is arranged over the second pulley. The mooring rope passes through the first pulley, the second pulley and the third pulley in sequence and then is connected with the counterweight box, and thus the structure that the drilling bucket mechanism downwards falls to drive the counterweight box to slide backwards along the sliding table is constituted. According to the rotary drilling machine with the automatic counterweight device, the mooring rope is directly connected with the counterweight mechanism, the effect that the torque of the front end and the rear end ofa manipulating table is balanced is achieved, and automatic weight counterbalance is achieved.

The invention relates to an air-conditioning outdoor unit and a piping system of the air-conditioning outdoor unit. The piping system comprises an exhaust pipe, wherein one end of the exhaust pipe is connected with a working port of a four-way valve; the other end of the exhaust pipe is connected with a compressor; a U-shaped pipe section is arranged at the lower part of the exhaust pipe; and a silencer is arranged on one side, close to the compressor, of the U-shaped pipe section. According to the piping system of the air-conditioning outdoor unit, the silencer is arranged on a section, far away from the compressor, of the exhaust pipe; the whole piping system only comprises the single silencer; the silencing performance of the silencer is better than that of the existing silencing structure; the silencer can also serve as a counter weight of the exhaust pipe at the same time; and the whole piping system is low in cost and high in efficiency.

The invention discloses an internal excitation automatic balancing device for propellers. The internal excitation automatic balancing device is designed to be installed at the propeller shaft, which can realize online suppression of propeller unbalanced vibration. The internal excitation automatic balancing device is a ring structure, which mainly includes two parts: a static ring and a moving ring. The static ring includes an excitation coil and a counterweight plate positioning Hall sensor; the moving ring includes two counterweight plates inlaid with permanent magnets and counterweights. When there is no external magnetic field, the position self-locking is realized through the side magnetic plate; ring connection. When the coil is energized, the weight plate can generate step rotation to compensate for imbalance. The present invention can design the installation structure according to the actual requirements of the propeller, and is respectively applicable to different installation methods and different balancing ability requirements. The invention has advantages in the weight of the excitation coil, the size of the balance ability, the convenience of installation and the like.
