The invention discloses a building method of a composite landscape wall. The method is technical characterized in that planting pools are arranged on one side or two sides of a wall body, a mural or embossment is arranged at the position, above the planting pools, of the surface of the wall body, the planting pools are filled with planting soil, and artificial hill stone, ground cover plants and arbors are arranged on the planting soil. The functional reflections of composite landscape wall built through the method to the space structure are shown in the following two aspects: the composite landscape wall can create space multiplicity, particularly, when the landscape wall environment needs to show the theme through space through space richness, a single landscape wall can only build a relatively single space, however, the composite landscape wall can divide the space to meet functional requirements through rich multiple spaces; the composite landscape wall can reflect space flowability more easily, particularly, due to the fact that the composite landscape wall is composed of multiple sets of landscape walls or scene building elements, spaces are mutually infiltrated and connected, and the dynamic flowing space can be more easily reflected; a large number of anions can be released, and air is effectively purified.

The invention discloses a relay protection testing and simulation control device. The relay protection testing and simulation control device comprises a relay protection control module, a simulation control module, a switching switch, a power amplifying module, a switching value input and output module and a power module. The relay protection control module is connected with a first data port; a simulation control module is connected with a second data port; the switching switch comprises two groups of switch paths; the power amplifying module and the switching value input and output module are connected with the relay protection control module through one switch path of the switching switch and connected with the simulation control module through the other switch path of the switching path. The relay protection testing and simulation control device integrates the functions of relay protection testing and simulation control, thereby meeting the functional requirements of a single relay protection object on testing operation as well as meeting and optimizing the functional requirements on distributed relay protection simulative testing, optimizing the system configuration of simulative testing of a distributed relay protecting system and improving the utilization rate of testing equipment of an intelligent transformer substation.

A plug with an unplugging assisting function comprises a plug body and conductive terminals. A button assembly, two transmission parts and a pushing portion are arranged on the plug body. The button assembly comprises two buttons and a spring, the buttons are symmetrically arranged on two sides of the plug body, the spring is arranged between the upper ends of the two buttons, and the lower end of each button is of sectorial gear structures. Each transmission part is a transmission gear set comprising a gearwheel and a pinion transmitting coaxially, the two transmission parts are respectively correspondingly arranged at the lower ends of the two buttons and are respectively mounted on the plug body through a positioning shaft, sectorial gear structures of the lower ends of the buttons are meshed with the pinions of the corresponding transmission gear sets. The pushing portion is mounted on the outer side of the front end of the plug body and forms a sliding matching relation with the plug body through the outer side and the inner side as well as a guide groove and a guide rack, the inner wall of the pushing portion is provided with a rack structure which is longitudinally disposed and is meshed with the gearwheel of the transmission gear set at the corresponding position, the pushing portion is driven to move back and forth along the plug body by rotation of the gearwheel, the front end of the pushing portion contacts with the surface of a socket. The plug with the unplugging assisting function has the advantages of convenience, quickness, labor saving and safety in unplugging.

The invention discloses a five-layered corrugated paper production line. The five-layered corrugated paper production line comprises a plurality of body paper racks used for unreeling body paper, facepaper preheating wheels, core paper preheating wheels, a single corrugated paper machine, an upward leading device, a double-layered paper rack, a conveying device, a triple preheating wheel, a pasting machine, a paper board forming machine, a driving device and an N.C. cutting and line pressing edge trimmer, wherein the face paper preheating wheels and the core paper preheating wheels are arranged between every two body paper racks; the single corrugated paper machine is used for roller forming of core paper and further compounding the core paper and face paper into single corrugated paper boards; the upward leading device and the double-layered paper rack are arranged above the single corrugated paper machine; the conveying device is used for conveying the single corrugated paper boards; the triple preheating wheel is used for preheating the single corrugated paper boards and the face paper; the pasting machine is used for pasting the face paper and two layers of the single corrugated paper boards; the paper board forming machine is used for compounding the face paper and the two layers of the single corrugated paper boards into a five-layered corrugated paper board; the drivingdevice is used for conveying the five-layered corrugated paper board; and the N.C. cutting and line pressing edge trimmer is used for shaping the five-layered corrugated paper board. By adoption of the five-layered corrugated paper production line, the corrugated paper board of a five-layered structure can be produced, and fixed-point notching treatment of the five-layered corrugated paper boardcan be conducted; and the automatic detecting and waste discharging functions are further achieved, and the number of discarded products in finished corrugated paper board products is decreased.
