The invention discloses a laser emitting and receiving device, which is arranged at the bottom of a boiler, and comprises two upper layer laser emitting and receiving units and a lower layer laser emitting and receiving unit arranged in parallel and separated by a certain vertical distance. The receiving units respectively include several uniformly arranged lasers, and the two lasers arranged on opposite walls respectively measure the horizontal distance from the lasers to the coke blocks dropped in the boiler. Also disclosed is a coke drop monitoring system and method in the furnace, which can obtain the height and horizontal position of the coke pieces falling in the furnace, so as to know the location of serious coking or large coke in the furnace, so as to carry out targeted operation adjustments measure. The overall coking and coke loss status in the furnace can be obtained, and the coal quality can be fed back according to the amount of coke, and the slagging equipment can be adjusted according to the monitoring results of the coke amount.

The invention discloses an interphase spacer bar and a tension bending test platform for fittings, comprising a power drive system (1), an upper wire direct response system (2), a wire tension adjustment system (3), a transmission tension adjustment system (4) and a lower wire The indirect response system (5); the power drive system (1), the upper wire direct response system (2) and the transmission tension adjustment system (4) are sequentially connected end-to-end through the traction wire rope (7) to form a closed-loop structure, and the upper wire direct response system ( 2) Comprising the first sub-wire spacer (21) and the second sub-wire spacer (22), the power drive system (1) can make the traction wire rope (7) reciprocate in the axial direction. The interphase spacer and fittings tensile bending test platform simulates the dynamic process of the interphase spacer and its matching fittings when the line is galloping, so as to carry out research on the structure, strength, and fatigue performance of the wire and the interphase spacer.

The invention discloses a micro-seismic monitoring early warning analysis system and method under the action of rock slope excavating perturbation. The system comprises a signal receiving unit, a signal acquisition unit, a signal storage and processing unit and an analysis and early warning unit arranged inside a slope; the signal receiving unit is used for receiving micro-seismic signals of a rock slope under the action of excavating perturbation and sending the micro-seismic signals to the signal acquisition unit; the signal acquisition unit is used for acquiring the micro-seismic signals and sending the micro-seismic signals to the signal storage and processing unit; the signal storage and processing unit is used for storing and processing the acquired signals and sending the signals to the analysis and early warning unit; and the analysis and early warning unit is used for analyzing the micro-fracture condition of the rock slope according to the processed signals and early warning the instability disaster of the rock slope. The system and the method can timely monitor and analyze the micro-seismic activity of the steep rock slope under the action of excavating perturbation and early warn the instability disaster of the slope, and are high in working efficiency, low in cost and wide in application prospect.

The invention discloses a novel method for preparing bionic adhesion micron-sized pillar arrays with different top end shapes. Top end structures are spatula-shaped, arc-shaped, planar and sunken respectively; pillars have micron-grade diameters; and the array has a high-aspect ratio structure. The method comprises the following steps of: forming a micron-sized pillar array on a silicon substrateby utilizing ultraviolet lithography and inductively-coupled plasma etching as main technical means; preparing a soft template with a micron-sized hole array structure by taking polydimethylsiloxane as a replication material; and performing film molding and curing on the solvent solution of high polymer material in the template by adopting different processes to obtain bionic adhesion micron-sized pillar array materials. The bionic adhesion materials obtained by the method have potential application value in the fields of biomedicine, precision industries, climbing robots and the like.
