The utility model belongs to the technical field of power cord, specifically relates to a power cord with independent switch control, including power plug and the power cord body connected in the tail end of power plug, the tail end still be connected with switch line, the other end of switch line is connected with switch controller, the surface of power cord body is connected with locating cylinder, the utility model discloses through the locating cylinder sleeve connection on the power cord body, simultaneously connecting cylinder sleeve connection on switch line, when need to tighten the switch controller of random suspension, then the locating cylinder, connecting plate and connecting cylinder are moved on the surface of power cord body, at this moment drive extrusion plate extrusion positioning spring, make the clamping and fixing of power cord body with extrusion plate, thereby conveniently tighten and fix switch line, avoid the random suspension of switch controller, avoid the security risk of the damage of switch controller, improve the life of power cord body use.

The invention relates to the technical field of forestry planting and ecological tending equipment, and discloses a device for assisting under-forest rattan climbing, the device comprises a bionic spine assembly, the bionic spine assembly comprises a first assembly and a plurality of second assemblies, one end of each of the first assembly and the second assemblies is connected with a target supporting wood through a top base, and the other end of each of the second assemblies is connected with a ground anchoring assembly, the first assembly is formed by connecting a plurality of first hollow cone units in an end-to-end nesting mode in series and forms a climbing center supporting body of the rattan rattan, the second assembly is formed by connecting a plurality of second hollow cone units in an end-to-end nesting mode in series, and the second assemblies are arranged around the first assembly in a circular array mode to form a cylindrical climbing channel. Through the synergistic effect of the center tensioning assembly and the ball socket matching structure, the physical contradiction between rigid supporting and flexible recycling is solved. By adjusting the axial prestress of the internal inhaul cable, the bionic spine assembly can be freely switched between a rigid columnar working state in which the bionic spine assembly bears the weight of rattan stems and a loose and soft flexible chain recovery state.

The application relates to the technical field of oil well control, and discloses a drilling tool three-proof safety lifting control method and device. The method detects and judges the state of a blowout preventer brake and the state of a wellhead in a well closing process and a well opening process in real time, and then starts a brake in time. The brake control gas path is controlled according to the size of a hanging weight value after the well is closed and before the well is opened, safety accidents such as drilling tool fracture or damage of a blowout preventer brake caused by lifting of the drilling tool are prevented, and the work efficiency of a well team on site can be improved.

The utility model discloses a kind of windproof and moisture-retention maintenance pads for building concrete, including maintenance pad main body, the inside of maintenance pad main body is installed with support pad, and support pad is uniformly provided with recess on it, the bottom of recess is uniformly provided with small hole, the inside of maintenance pad main body below support pad is filled with sponge layer, the bottom of maintenance pad main body is uniformly provided with through-hole, the top of maintenance pad main body is uniformly installed with convex column, and the side of convex column is uniformly provided with semicircular groove, the side of semicircular groove is uniformly provided with fixed mechanism. The utility model is by with water evenly sprinkled on the surface of maintenance pad main body, water will flow to the recess on support pad, and is absorbed by sponge layer by small hole downward permeation, and then flow to the surface of building concrete by through-hole, provide moisture for concrete, and simultaneously, the moisture absorbed by sponge layer can keep certain temperature on the surface of concrete.

The application discloses an error detection and automatic recovery method and related equipment, and relates to the technical field of digital circuit design. The error detection and automatic recovery equipment comprises a bus bridge. The bus bridge comprises a bus bridge module. The bus bridge module is used for performing error detection on a slave functional module in response to an access request sent by a host end to the slave functional module, obtaining an error detection result, and performing automatic recovery on the slave functional module when the error detection result indicates that an error occurs. The bus bridge module is further used for sending access feedback to the host end. The application performs error detection and automatic recovery autonomously through the bus bridge, directly feeds back access results to the host after recovery, avoids bus suspension caused by unresponsive slave equipment without the intervention of the host, effectively prevents bus jamming and system crash, and thus significantly improves the overall reliability and availability of the system.
