Mine monkey vehicle detection control system

InactiveCN103072581Aconvenient for passengersReduce power loss
The invention relates to a mine ropeway detection control system for carrying out detection control on a ropeway on a mine. The mine ropeway detection control system comprises power supply modules, detection modules, monostable trigger modules, a PLC (Programmable Logic Controller) control module and an executing module, wherein each power supply module comprises an LM2576-12 voltage stabilizing chip, each detection module comprises a microwave detection module and a key detection module, the monostable trigger modules detect level changes in signals and carry out delay on the signals to control opening and closing of a relay, the PLC control module receives a relay opening and closing signal, and transmits data to the executing module after the data is analyzed and processed; and the executing module comprises a frequency converter module, an indicator lamp module and a horn alarm module, data information transmitted by the PLC control module is executed , a motor operation mode is controlled to be displayed, the detection result is ensured by using microwave detection and key detection, whether high and low levels alternatively control a relay to be opened or closed is judged rapidly through monostable trigger circuits, a plurality of detection modules automatically detect whether people take buses from a plurality of access adits to control the operation mode of a motor, and thus the energy loss is reduced.

One-step spinning machine capable of conducting entwisting clockwise and one-step spinning method

ActiveCN103060963ACompactreduce power loss
The invention provides a one-step spinning machine capable of conducting entwisting clockwise and a one-step spinning method. The one-step spinning machine comprises a carding roller, a cover, a fiber feeding mechanism, a yarn winding mechanism and an air sucking device. The one-step spinning machine is characterized in that an irregular-shaped pipe formed by a conical pipe and a trapezoid pipe is arranged below the carding roller. The trapezoid pipe is formed by defining two trapezoid steel plates and two trapezoid mesh plates, and a U-shaped fiber cohesion area formed by a semi-circular-arc mesh plate is arranged at the outlet end of the trapezoid pipe so as to achieve cohesion of fiber in the irregular pipe. One side of the cohesion area is connected with a rotation flow entwisting pipe in butting mode, and the inner diameter of the rotation flow entwisting pipe and the U-shaped cohesion area form a straight smooth yarn channel. Compressed air enters along an air inlet hole of a lateral wall of the rotation flow entwisting pipe to form forward rotation flow to finish entwisting of strips and push the yarn to move forward. Fiber is fully separated, stretched, becomes parallel and is combined evenly on one device, and the one-step spinning machine is simple and compact in structure, convenient to machine and manufacture and low in cost. The one-step spinning method achieves purposes of high speed, high yield, high efficiency and high quality.

Water surface cleaning boat and floating object pushing device of water surface cleaning boat

The invention provides a water surface cleaning boat and a floating object pushing device of the water surface cleaning boat. The floating object pushing device comprises a floating object pushing frame, a pushing plate, an ascending and descending mechanism and a rotation regulating mechanism, wherein the floating object pushing frame extends in the length direction of the cleaning boat, the back end part of the floating object pushing frame is rotationally arranged at a bow, the pushing plate can rotate around the front end part of the floating object pushing frame and is arranged in a way of being intersected with the horizontal plane, the ascending and descending mechanism is used for driving the front end part of the floating object pushing frame to rotate around the back end part and enables the pushing plate positioned at the front end part of the floating object pushing frame to upwards ascend or downwards descend, the rotation regulating mechanism is arranged on the floating object pushing frame and is used for pushing the pushing plate to inwards incline towards the bow, the pushing plate is a mesh plate, in addition, the pushing plate is arranged in a way of transversely extending, and the ascending and descending mechanism is arranged on a deck of the bow. The water surface cleaning boat and the floating object pushing device have the advantages that floating objects on the water surface can be gathered in a wide range, and in addition, the water entering angle of the pushing plate can be regulated according to different floating objects, so the power consumption of the cleaning boat is little, meanwhile, the pushing plate can also upwards ascend or downwards descend, the floating objects can be comprehensively gathered according to the suspension degree of the floating objects, in addition, the structure is simple, and the implementation is convenient.

Pressure regulating system of hydraulic drive air conditioner of crane cab

PendingCN107867146Areduce power lossAchieve operation and normal protection
The invention discloses a pressure regulating system of a hydraulically driven air conditioner in a crane control room. The oil outlet of the hydraulic pump of the main engine is divided into two paths through a proportional valve, and one path is controlled by an electromagnetic system composed of a hydraulic pipeline, an overflow valve and a throttle valve. The valve is connected with the air conditioner motor, and the air conditioner motor drives the air conditioner compressor to run through the coupling, and the electromagnetic control valve is adjusted and controlled in real time by the air conditioner control unit according to the collected values ​​of the pressure sensor and temperature sensor; the other way is through the hydraulic pipeline, The swing buffer valve is connected with the swing motor. The control valve composed of overflow valve and throttle valve is connected with the control unit to protect the pressure of the air conditioner motor, automatically adjust the pressure, and realize the stable operation and normal protection and cut-off of the air conditioner system. The air conditioner motor is connected to the air conditioner compressor through a coupling, which drives the air conditioner compressor to run stably and realizes the cooling performance of the air conditioner.
