The invention relates to a manufacturing method of a mine blow dryer, and the method comprises the following steps: manufacturing a foundation, namely weaving and expanding 1300D or 1500D ultralow contraction twisted polyster fiber filaments serving as warps and wefts by use of a braiding machine to form the gridded foundation; manufacturing a PVC (polyvinyl chloride) rolling film; and laminatinga film on the PVC rolling film and foundation, which are subjected to high temperature plasticizing, by a film laminator to obtain the mine blow dryer. The mine blow dryer manufactured by adopting the method provided by the invention has the advantages of good abrasive resistance and tear resistance, light weight, good water-proof, anti-fouling, mildew-proof, anti-flaming and anti-static effects and long service life, is ageing-resistant and can be formed singly.

Flatness measuring device and using method thereof
PendingCN111141236ASimple structureReduce working at heightsUsing optical meansLaser rangingMeasurement device
The invention relates to a flatness measuring device and a using method thereof. The flatness measuring device comprises a main ruler and a laser range finder, wherein a horizontal bubble is arrangedon the top face of the main ruler, a telescopic adjusting piece is arranged on the bottom face of the main ruler, the length of the adjusting piece is correspondingly adjusted according to the horizontal bubble, and the main ruler is made to be horizontal; the laser range finder is mounted on the top surface of the main ruler and can be moved and adjusted in the length direction of the main ruler,the laser range finder is moved along the main ruler and emits laser to a to-be-measured structure to measure the distance between a multiple sets of main rulers and the to-be-measured structure, andtherefore the flatness of the to-be-measured structure is obtained through comparison. Thus, the problem that the flatness of the to-be-measured structure is difficult to measure is effectively solved, the measurement precision and the construction quality can be ensured, in addition, the potential safety hazard is reduced, the safety of measurement personnel is ensured, and the measurement device is simple in structure and easy to realize.

Acceleration effect-adjustable two-wheeled electric vehicle speed regulation method and speed regulation system
PendingCN112061280AAvoid breakingReduce lossSpeed controllerCycle control systemsElectric machineryElectric cars
The invention discloses an acceleration effect-adjustable two-wheeled electric vehicle speed regulation method and a speed regulation system. The acceleration effect-adjustable two-wheeled electric vehicle speed regulation method comprises the following steps that a control button is pressed, and a speed regulation handle is rotated to carry out normal acceleration driving; and when the speed regulation handle is rotated by mistake, only low-speed driving with the highest speed of 3 KM / H can be conducted, and when a brake is pressed down, traction stopping and brake disc braking are conductedat the same time. The speed regulation system involves a permanent magnet, capable of moving relative to a hall sensor, in an accommodating cavity, a telescopic rod is arranged on one side, far away from the hall sensor, of the permanent magnet, a spring is connected between the permanent magnet and one end of the accommodating cavity, a linkage wire is connected between the permanent magnet and the speed regulation handle, the hall sensor is connected with a speed regulation controller, and the speed regulation controller is electrically connected with a speed sensor and a motor. The method and the system can improve the safety and have the advantages that the brake effect and the durability are relatively good.
