The invention relates to a method for locking network equipment in a network. First set up the ports of the network device, so that some ports are set to be available after startup, and some ports are set to be available after startup and through the unlocking process; Control module; after the network device starts, it sends an unlocking request to the unlocking control module; the unlocking control module sends the unlocking request back to the network device after corresponding processing, and completes the unlocking work. In this way, if the network device is not used in a predetermined network, or the user of the network device does not know information such as its key, the network device cannot be put into a working state. Therefore, the present invention can reliably lock network equipment in a certain network, and only users with legal identities can use the network equipment, thereby effectively preventing network equipment from being stolen and reducing accidental losses of network operators.

The invention relates to a double-layer metal cladded flame-retardant electric cable which is manufactured by cladding an insulation layer and a conductive core wire, wherein the conductive core wire is manufactured by cladding double layers of different metal materials; the insulation layer is made of a smokeless and flame-retardance nano modified polyvinyl hydrocarbon polymer insulation material; a flame-retardance jacket is cladded outside the insulation layer; and the conductive core wire is made of copper clad aluminum, copper clad steel or aluminum clad steel. The double-layer metal cladded flame-retardant electric cable is safe and reliable, has less smoke generation amount in a combustion environment when accidents happen, better flame retardance and no harmless gases or corrosivegases and can be used for effectively reducing accidental loss and reducing material cost.

The invention discloses a differential planetary reduction gear for a bridge crane. The differential planetary reduction gear for the bridge crane comprises a reduction gear frame; a main motor is arranged on the outer side of one end of the reduction gear frame; an output shaft hole frame is installed at the other end of the reduction gear frame; standby motors are symmetrically installed on two sides of the main motor; a power shaft of the main motor is connected with a transmission shaft through a flange plate; standby power shafts of the standby motors are embedded and clamped into standby shafts; input gears are installed on the standby shafts and connected with transmission gears through transition gears; the transmission shaft is seeved with the transmission gears and connected with an output shaft through a three-level planetary gear set; the output shaft penetrates through the output shaft hole frame, extends to the outer side of the reduction gear frame and is fixedly installed on one side face of the three-level planetary gear set through a bearing pedestal plate; the three-level planetary gear set is connected with a gear ring on the inner wall of the reduction gear frame; and the transmission efficiency is improved.

The invention relates to aquaculture equipment, in particular to a self-closing culture cage comprising a net cage and a buoyant box. The net cage comprises a support connected to the buoyant box and a culture net with an open upper end. The open end of the culture net is provided with a pair of closing bars connected with the support. At least one of the closing bars is slidably connected with the support and is provided with a closing bar shifting mechanism. The closing bar shifting mechanism comprises a closing rope with one end connected to the corresponding closing bar, a weight connected to the other end of the closing rope, and a weight balance mechanism; the weight balance mechanism comprises a hanging bar hooked to the closing rope and a first float connected to the hanging bar; the first float locates in the buoyant box; a locking block and a locking channel fitting each other are arranged between transverse bars in a pair. The self-closing culture cage has the advantages that when the buoyant box with water coming in sinks, the opening of the buoyant box can automatically close; the problem that aquatic products cultivated in the culture net escape likely when the existing culture cage submerges in water.

The invention discloses a speed control system and a speed control method of a titanium welded pipe production line. The system comprises a programmable controller, a counting module, a molding unit direct current speed regulator, a sizing unit direct current speed regulator, a pulling unit direct current speed regulator and an operating screen, wherein the counting module is connected with a thermal treatment front coder and a thermal treatment rear coder respectively; the thermal treatment front coder is positioned between a sizing unit and thermal treatment equipment; and the thermal treatment rear coder is positioned between the thermal treatment equipment and a pulling unit. The thermal treatment front coder and the thermal treatment rear coder are arranged in front of and behind thethermal treatment equipment respectively and feed a measured practical titanium pipe speed to the counting module, and the programmable controller can perform automatic comparison and fine adjustmenton the set speed of a production line unit according to two practical speeds of the counting module, so that speed before and after thermal treatment is kept consistent, and problems such as pressuremarks, which are caused by speed difference, on the surface of the titanium pipe, elongation and fine drawing of the titanium pipe, and the like are solved.

The invention discloses a child monitoring and protection intelligent access control monitoring system, which belongs to the technical field of access control monitoring. The invention makes it possible for a child to press the door opening button in the access control system through the setting of a perception drive mechanism, an identification drive mechanism, and a monitoring management center. switch, when trying to get out of the community, the system will spontaneously recognize the face of the child, capture its facial information, and send a warning message to the parents of the child, so that the parents can know in time that their child may run out of the community alone risk, prompting parents to check or look for children at the first time, which can significantly enhance the protection function of children, effectively reduce the occurrence of children's accidental loss, and can effectively avoid unnecessary identification, and the intelligent access control monitoring in the present invention The system can be directly used in conjunction with the existing access control system without destroying or abolishing the original access control system, which can effectively save costs and greatly improve practicability.

The invention provides a device and method for improving charging efficiency of a solar battery. Two groups of solar battery packs are used for charging accumulators with different nominal voltages; when the accumulator with high nominal voltage is being charged, the two groups of solar battery packs run automatically in the form of being connected in series with each other, thus obtaining high-voltage low-current output; the output power of the solar battery pack is the maximum value; when the accumulator with low voltage is being charged, the two groups of solar battery packs run automatically in the form of being connected in parallel with each other, thus obtaining low-voltage large-current output; and the output power of the solar battery pack is also the maximum value. The device and method for improving the charging efficiency of the solar battery have the advantages of overcoming the defects of the prior art, greatly improving the charging efficiency when the same solar power supply is used for charging the accumulators with different nominal voltages, and sufficiently utilizing the installation capacity of the solar battery pack.
