A rhombic outer facing panel curtain wall structure and a construction method thereof, comprising a keel framework and a curtain wall panel; the keel framework is a rhombic grid structure, and the top angle of the rhombus is 60 degrees; the keel framework comprises a main keel and a secondary keel; a clamping strip is arranged on the outer side of the main keel and the secondary keel along the long axis of the corresponding keel; a strip-shaped groove is arranged on the outer side of the clamping strip; the curtain wall panel is rhombic, the four peripheral edges of the curtain wall panel are respectively bent inward to form a flange; the flange is correspondingly inserted into the strip-shaped groove and is fixed with the clamping strip through a fastener; a small hole is arranged on the panel surface of the curtain wall panel at intervals, and a recess is arranged at the lower part of the curtain wall panel; the vertical section of the recess is polygonal; a recess groove is arranged on the vertical side wall of the recess; a decorative lamp is installed in the recess groove, and a transparent cover is arranged at the slot opening of the recess groove. The technical problem that the panel of the traditional aluminum plate curtain wall is a two-dimensional plane structure, has no novel visual sense and cannot meet the light effect of the project is solved.

The invention relates to the technical field of glass production equipment, in particular to high-precision tempered glass curved surface forming equipment which comprises a machine body, a first roller way and a second roller way and further comprises an air inlet channel, a flexible shaft, a fixing rod, a driving unit, an air outlet channel, a movable assembly and a flow blocking assembly. The first roller way and the second roller way each comprise a plurality of sets of T-shaped blocks connected in sequence, the air inlet channels are connected with the T-shaped blocks, the fixing rods penetrate through the T-shaped blocks, the driving units are arranged on the fixing rods and connected with the flexible shafts, the T-shaped blocks are hollow, open grooves are formed in the ends of the T-shaped blocks, and the air outlet channels are arranged in the T-shaped blocks. Through the driving unit and the flow blocking assembly, the wind direction and the wind pressure of cold air can be dynamically adjusted in the process that the roller drives the glass to move back and forth for cooling, so that the wind pressure is minimum when the cold air directly blows the glass, and the wind pressure is increased when the air outlet channel obliquely blows towards the movement direction of the glass; and the forming precision and the forming efficiency of the glass curved surface are effectively ensured.

The present application relates to visual detection mechanical equipment technical field, especially relates to a kind of belt composite visual screening machine, including workbench and install on the workbench belt conveying line, first visual screening matrix, second visual screening matrix, pneumatic discharge mechanism, by improving discharge passage to swing adjustment, when blowing out workpiece by air blowing nozzle blowing, discharge passage will receive instruction simultaneously, swing to horizontal state, workpiece is received, since receiving, airflow penetrates discharge passage, and after receiving workpiece in discharge passage, it will quickly change to inclined state, originally horizontal penetration airflow is truncated by inclined discharge passage, directly reduce airflow velocity, so that the speed of workpiece changes with airflow, quickly reduce, then workpiece is exported along the inclined discharge passage, ensure the stability of workpiece output, also reduce the probability of appearance scratch and damage of workpiece due to high-speed impact discharge passage.

The application relates to an air cooler. The purpose is to provide an air cooler fan bridge with low wind resistance, adjustable inherent frequency and TLD damping function, which also has the characteristics of simple structure and convenient use. The technical scheme is an air cooler fan bridge with low wind resistance, adjustable inherent frequency and TLD damping function; characterized in that: the outer sides of the middle parts of the two main beams are guide surfaces which are inclined inward from top to bottom, and the two sides of the support beam are guide surfaces which are inclined to the vertical center line from top to bottom; so as to guide the airflow.

The utility model discloses a dustproof and waterproof protective screen cover of an integrated video linkage information release screen, which relates to the technical field of information release screen protection and comprises the integrated video linkage information release screen, and a high-strength transparent film is arranged on the device so that pedestrians can conveniently observe information at the upper end of the integrated video linkage information release screen. Meanwhile, the high-strength transparent film can isolate the integrated video linkage information release screen from the outside, so that small-particle gravels carried in strong wind are prevented from being blown to the upper end of the integrated video linkage information release screen under the action of wind power; an adjusting motor is installed to be matched with a wind direction sensor, when the wind direction sensor detects that strong wind blows in the forward direction of the device, the adjusting motor can drive the integrated video linkage information issuing screen to rotate by a certain angle, the top of the integrated video linkage information issuing screen faces the wind direction, and the wind pressure borne by the integrated video linkage information issuing screen is reduced; and the integrated video linkage information release screen is prevented from shaking.
