The invention discloses an automatic reducing low-deformation offshore deep-water cage, relating to a cage for marine aquiculture. The invention is capable to reduce the deformation of the cage and the flow rate of the sea water inside the cage. The invention comprises a buoyancy frame, a cage, a sinking ring, a sinking block and an anchoring rope. A supporting and lifting control ring bigger than the buoyancy frame and the diameter of the sinking ring is arranged at the one second depth of the cylindrical cage; a water inlet and a water outlet are arranged in the pipe wall of the supporting and lifting control ring; a girdle rubber inner bag which regulates the lifting and descending of the cage is arranged in the ring pipe; an air-valve is installed in the rubber inner bag and connectedwith the air supply by a pressure hose; between the outer ring and the supporting and lifting control ring of the double-ring buoyancy frame, the bottom outline of the cylindrical cage and the bottomsinking ring, a plurality of flexible ropes are located and connected according to the ring at geometric proportion, and a netting is arranged among the connecting ropes of the three rings; and finally, a flexibly connected automatic reducing low-deformation offshore deep-water cage with a cylindrical inside and a two-cone platform outside is formed, the stress point of the anchoring rope of the cage is arranged at the supporting and lifting control ring.

The invention provides a drive control method and system for a high-torque permanent magnet AC servo motor. During the operation of the AC servo motor, the current of the coil winding of the motor and the working voltage of the motor are collected by mutual inductance, so as to determine the real-time driving force and judgment of the motor output. Whether the motor is currently in an overloaded lifting state, thereby controlling the on-off state of the motor; in addition, when the object in the motor is currently in an unbalanced center of gravity, the lifting speed of the object can be adaptively reduced, which can reduce the output drive of the motor. The magnitude of the force ensures that the object can be lifted smoothly, thereby effectively avoiding the object from swinging greatly during the lifting process, improving the stability of the lifting motion of the object, and maximizing the normal and continuous output of the driving force by the motor.

The invention relates to a full-automatic fabric cutting machine. A machine frame is provided with a horsehair conveyor belt, a feeding device is arranged above the machine frame, the feeding device is provided with a cutting mechanism, the cutting mechanism comprises a fabric cutting frame, the fabric cutting frame is provided with a cutting knife sleeve, the lower part of the cutting knife sleeve is provided with a cutting knife groove, the cutting knife groove is communicated with the cutting knife sleeve, the cutting knife sleeve is internally provided with a cutting knife lifting pulling rod which is matched with the cutting knife in the cutting knife groove, the upper part of the cutting knife lifting pulling rod is connected to a cutting rotating seat in a hinged mode, the cutting rotating seat is also connected to a cutting rotating rod in a hinged mode, the other end of the cutting rotating seat is arranged on a sleeving connecting shaft on a cutting installing plate of the fabric cutting frame in a sleeving mode, the other end of the cutting rotating shaft is connected to a cutting rotating sleeve, and the cutting rotating sleeve is matched with a cutting lifting motor on the cutting installing plate. According to the full-automatic fabric cutting machine, the biggest lifting range is limited, the speed capable of slowing down lifting is adjusted at the same time, and the situation that the cutting knife destroys the conveyor belt is sharply avoided.

The invention discloses a granulator elevator, which comprises a mounting frame and a reducer casing installed on the mounting frame. The left and right ends of the reducer casing are open, and the left and right opening ends of the reducer casing are respectively provided Left cover and right cover; Among them, motor, gear shaft, driving sprocket shaft, first gear, hub friction disc, second gear, driving sprocket, etc. are installed in the reducer housing, in addition, chains and hooks are also included. When in use, when the motor starts, stops, or changes direction, a rigid impact will be generated at the gear mesh, and the friction disc can play a role of buffer protection; in addition, when the heavy load is overloaded, the friction disc will rotate relative to the secondary gear and the hub to prevent the motor from rotating. In addition, the up and down of the lifting mechanism depends on the input torque of the motor to drive the sprocket through gear reduction, and the sprocket occludes the ring chain to realize the lifting of the granulator. Achieve the purpose of deceleration and precision lifting, and at the same time play a role in smooth transmission.

The invention discloses a dual-servo motor control method for a track detection device of an amusement facility. Two motors are used to respectively drive the drive wheels on the left and right sides, wherein the first servo motor is the master, the second servo motor is the slave, and the second servo motor works In the torque mode, adjust the output torque of the servo motor 2 according to the current feedback value of the servo motor 1, so that the current feedback values ​​of the two are close to each other, so as to ensure that the working states of the two are similar, and avoid the close situation between the two. The structure is simple, the response speed is fast, the reliability is high, and the flexibility is good. It can effectively and stably control the running of the track detection device of the amusement facility, and better realize the comprehensive detection of the track by the track detection device of the amusement facility.

The invention relates to a construction process of floral tube dry filling piles with obvious engineering effect, low economic cost, high technical content and high resource utilization by improving the inherent characteristics of cement, soil strata, materials and the like. The process comprises the following steps of: (1) pore-forming process: 1, using dry pore-forming process for pore-forming piles above underground water level; 2, positioning a pore opening machine and a drill for pore-forming piles below underground water level; drilling in at low stroke and high rotary speed with clean water; reaching a drilling-in depth; lifting to a pore opening at unified stroke and high rotary speed with clean water; drilling into a pore bottom at unified stroke and high rotary speed with clean water; rotating at high speed and filling with cement mortar; and lifting to the pore opening at high rotary speed and low stroke after cement mortar returns to the pore opening; moving the drill; (2)the process of installation and pile molding by filling: adopting the following steps for installing pile pores and filling dry cement above or below water level: installing floral tubes; correcting the pore position of the floral tubes; filling the dry cement; and filling the dry cement to an elevation required by the design.
