The invention relates to the technical field of water utilization devices, in particular to an integrated electromagnetic valve structure and a pipeline water dispenser. The integrated electromagnetic valve structure comprises a valve body. An electromagnetic valve unit is arranged in the valve body and comprises a main spring, a movable iron core, a battery cell, a diaphragm plate, a water inlet for flowing water to flow in, and a water outlet for the flowing water to flow out. The integrated electromagnetic valve structure further comprises a water inlet channel communicating with the water inlet. The movable iron core is driven to seal or open a water passing hole under the attraction effect of the battery cell so that the water inlet channel can be sealed or opened. A pressure reduction valve unit is further arranged in the valve body and located at the connection position of the water inlet channel and the water outlet so that the water pressure change value of the water outlet can be kept within a certain range. The pipeline water dispenser comprises a water entrance. The integrated electromagnetic valve structure is connected to the water entrance. Use of matched materials is reduced, water leakage points of complete machines are reduced, the water leakage possibility is lowered, and the assembly efficiency is improved.

The invention discloses a subsoiler capable of measuring the mechanical resistance of soil continuously, and aims to measure the mechanical resistance of the soil. A displacement sensor is used for measuring the tillage depth of the subsoiler and installed between a machine frame and a profiling wheel. A scraper knife of the subsoiler is hinged to a sliding block, and a hydraulic cylinder is connected with the sliding block. Under the condition that the tillage resistance is not large and the scraper knife can not be damaged, the hydraulic cylinder prevents the scraper knife from moving backwards. In the tillage process, if the scraper knife meets foreign bodies, the value of the resistance on the scraper knife exceeds the set pressure value of the hydraulic cylinder, the hydraulic cylinder contracts, and the scraper knife moves backwards and avoids the foreign bodies. The scraper knife is connected with a force sensor used for measuring the resistance of tillage.

The invention belongs to the field of wind power generation, particularly to a variable speed constant frequency method for wind power generation and a device thereof; the variable speed constant frequency method obtains signals of wind speed, rotating speed of a wind wheel and the rotating speed of a generator by monitoring, and inputs the signals to a PLC (Programmable Logic Controller) controller; the PLC controller calculates according to certain control algorithm and outputs displacement control signal to regulate the displacement of variable hydraulic pumps and variable hydraulic motors, thereby regulating the rotating speed of the wind wheel to follow the wind speed to operate at variable speed, and regulating the generator to operate at constant frequency; the variable speed constant frequency device comprises a wind wheel, two variable hydraulic pumps, two variable hydraulic motors and a generator; a three-position three-way electromagnetic directional valve is used for controlling the type and the number of the variable hydraulic pumps in real work; and a three-position four-way electromagnetic directional valve is used for controlling the type and the number of the variable hydraulic motors in real work. The method and device provided by the invention realize variable speed constant frequency power generation of a wind power generation device by regulating the displacement of the variable hydraulic pumps and the variable hydraulic motors, thus improving energy capture efficiency and achieving stable energy output of the generator.

The invention provides a single-tub washing machine drainage structure and a single-tub washing machine comprising the same. The single-tub washing machine drainage structure is used to control the opening and closing of the washing tub drain of the single-tub washing machine. The washing tub has a single-tub structure, and the drainage outlets are distributed in the circular area at the bottom of the washing tub , the center of the ring-shaped area is located on the rotation axis of the washing tub, and the drainage structure includes: a blocking block, which is movably arranged along the axial direction of the washing tub and has a blocking The first working position of the drain opening and the second working position of opening the drain opening, the driving mechanism is used to drive the blocking block to move to the first working position or the second working position. The invention can simplify the drainage structure of the single barrel washing machine and is convenient for implementation.
