The invention discloses a control design method of a regional clock cassette mechanism, which belongs to the technical field of timing instruments. The regional clock cassette mechanism comprises a cassette mechanism splint, a stepper motor, a clock hand component and a gear reducing transmission mechanism; the control design method of the regional clock cassette mechanism has the characteristicsthat: the regional clock cassette mechanism comprises a synchronous reducing motor, a gear on the output end of the synchronous reducing motor is directly meshed and connected with a second wheel which is directly arranged on a second wheel shaft, and a hole is arranged on the second wheel and a photoelectric switch is respectively arranged on both ends of the hole. The control design method comprises the steps of power supply to the clock cassette mechanism, the driving to a time base, an hour hand, a minute hand and a second hand, and the setting and the control of alarm information feedback items. Compared with the prior art, the control design method of the regional clock cassette mechanism has the significant and substantial characteristics and significant progress that: the second hand continuously works, a clock can still work for three hours after a 220V main power supply is disconnected to wait for the connection of the main power supply; but if the power from the main power supply is still not obtained, the hour hand and the minute hand are automatically reset to a 12 o'clock position, so that the alarm information that 'the clock fails to work, please pay attention and do not delay the travel time' and the like is sent to a traveler.

The invention provides a control method and device of storage battery charging of a communication station. The communication station comprises a generating set, an input end of commercial power, a storage battery and a communication power supply. The generating set and the input end of commercial power are used for supplying a working power supply to the communication power supply, and the communication power supply is used for supplying power to the load of the communication station and the storage battery. Concretely, the control method comprises: obtaining a commercial power losing signal and a generator starting signal; generating a storage battery charging limited signal according to the commercial power losing signal and the generator starting signal; and limiting the communication power supply to charge the storage battery when the generator is in the power state according to the generated storage battery charging limited signal. The control method and device of storage battery charging of the communication station can limit the generator to charge the storage battery when the commercial power of the communication station breaks down, so that the power supply capacity of the generator is reduced, and the simple configuration of the generator capacity is realized.

The invention discloses a numerically-controlled double housing planer. The numerically-controlled double housing planer comprises a double housing planer base, a carriage, left and right upright columns, a cross beam and a control unit, wherein planning and cutting mechanisms are arranged on front and back sides of the cross beams, and each planning and cutting mechanism comprises a horizontal feed sliding base and a lifting carriage. According to the double housing planer, the carriage, the horizontal feed sliding bases and the lifting carriages are driven by lead screws, and the stability is higher; the planning and cutting mechanisms on two side surfaces of the cross beams are provided with independent lead screws and motors, and workpieces can be machined in a non-interfering manner, so that the working efficiency is higher; the vertical movement of a cross beam of an existing double housing planer is replaced by the vertical movement of the lifting carriages, so that the carrying load of machinery is reduced; and the problems of short service life, poor stability and low working efficiency of the existing double housing planer are solved.

The invention discloses an automatic feeding and reflux wine steamer. The automatic feeding and reflux wine steamer includes an automatic feeding mechanical structure, a steaming barrel structure, and a condensation cover structure. The automatic feeding mechanical structure includes a frame base, a support plate, a belt, and a rack , feeding sheet, the structure of the steaming barrel includes the outer wall of the steaming barrel, the inner wall of the steaming barrel, the rubber plug, the top plate of the screen, the middle plate of the screen and the bottom plate of the screen. The functions of mixture of fermented grains, layered condensation and wine liquid reflux not only overcome the problems of difficult operation, cumbersome feeding, dry pot and low yield of wine in the existing wine steaming equipment, but also provide a new way for the distillation link in the wine steaming process. Provides a guarantee of stability.

The invention discloses a safe energy-saving intelligent elevator, comprising a lift car, a door system, a guide rail, a balance system, an overload limit device and a control system which are located in a shaftway; the lift car comprises a car body and a lift car frame, and the door system comprises a lift car door and a layer door; door stop devices are arranged on both upper and lower ends of the two sides of the lift car door, each door stop device comprises a fixing component and a door stop component, the balance system comprises a counterweight and placing grooves arranged in two sides of the guide rail, and the counterweight is connected on the top of the lift car by a dragging steel rope and can move up and down along the guide rail. The door stop devices are arranged on the upper and lower ends of two sides of the lift car door, when the lift car door is opened, a spring drives an inner rod to extend to a direction vertical to the lift car door so as to block the lift car door, such that entering and exiting safety of taking personnel is ensured; a total weight of the counterweight is changed by second electric push rods and a bidirectional push rod, such that the elevator lift car and the counterweight are kept balanced all the time, and further the up and down operation safety of the elevator is ensured.

The invention relates to a numerically controlled planer, in particular to a slicing mechanism for the numerically controlled planer. The slicing mechanism comprises a horizontal feeding side rest and a lifting carriage. Vertical motion of a transverse beam of an existing planer is replaced by vertical motion of the lifting carriage, and since the lifting carriage is lighter than the transverse beam, carrying load of a machine is lowered, and service life of the machine is prolonged. By the aid of the slicing mechanism, the problem of short service life of the existing planer is solved.

The application discloses a three-in-one power climbing rope and three-in-one power climbing rope equipment. The three-in-one power mountaineering rope includes nylon fiber rope core and nylon fiber sheath, the sliding rate of the sheath core is less than 0.1%, the static elongation rate is less than 8%, the first maximum elongation rate is less than 35%, the shrinkage rate is less than 5%, and the knotting coefficient The linear density is less than 1, and the linear density is less than 50 g / m. The diameter of the power climbing rope is 8.5-9.32 mm, and the diameter of the rope core is set at 7.2-8.3 mm. Power mountaineering rope combines the functions of traditional single rope, half rope and double rope. It is light in weight and high in strength. It can effectively absorb the impact force of the user and has a good buffering effect. In industrial operations, outdoor rescue and other fields with a fall coefficient greater than or equal to 0.3, it reduces the user's carrying load and effectively protects the user's personal safety.
