Steel surveying and mapping training device

Technical structure parameters:

The overall steel plate structure is adopted: configure the drawing desktop, the computer display platform, the m--n cabinet, tool drawing and keyboard pumping, etc.;

Left and right desktop substrate: The m--n desktop on the left adopts the standard No. 1 (900 × 600 × 20mm thick) Northeast beylum thick drawing special board. The desktop flat, synchronous control adjustment adjustment tilt 0-70 °. Turn the handle with the hand shake by the side, which is convenient and reliable.

3) Multiple storage space: the left and right configuration tools of the lower part of the desktop and the keyboard pump to meet the needs of d--ly teaching drawings and computer operations; the open m--n cabinet on the right side of the desktop body is convenient for placing the host;

4) Stability adjustment foot pads: The bottom is used to adjust the screw foot pad or universal wheel with plastic wood levels at the bottom. It can be anti -slip and noise, and has the regulatory function to ensure the stability of the desktop and the strong structure.

M--n material specifications and surface treatment:

1) Drawing desktop brackets use high -quality torque pipe materials (30 × 60 × 1.0mm) and steel plate materials above 0.8mm; all desktop structure or component steel are national standard products, and the welding parts must be carbon dioxide protection welding process. Welded, the solder joints are firm, smooth, and beautiful, with no bubbles, burrs and leakage welding, and fake welding. They have the resistance to wear resistance and scratch. Oil removal, rust removal, and pickled phosphorus treatment to ensure that no plastic peeling and anti -rust are occurred.

2) The desktop substrate uses the northeast beef wood thickened professional drawing board (900 × 600 × 20mm thick), which has the performance of durable and difficult to deform. The melamine desktop tablet is formed with high frequency thermal pressure at one time. The n--ling force is strong, it is not easy to expand, it is not easy to deform, and it is firm and durable. The edge of the high -quality PVC plus imported thermal solution fully automatic mechanical border seal is adopted by 1.5mm. The edges are neat and smooth, and the layers are clear.

3) Steel frame knot student table configuration (optional):

(1) 90cm butadiest ruler

(2) 90*60cm No. 1 drawing board

(3) Precision Drawing Instruments (5 sets of 5 pieces)

(4) 25cm curve board

(5) 30cm multi -use oblique triangle board

1. System summary

"Tr--ning Device of Frequency Conversion Constitutional Water Supply System" integrates PLC, frequency conversion speed regulation, process control, and engineering configuration technology. It consists of two major parts of the six -story residential fire and water supply system (physical model). The control platform two parts include Programmable controller, inverter, inverter magnetic driver pump, dormant pump, fire pump, pressure transmitter, pressure instrument, water pipeline, fire hydrant, home water faucet, storage pool and other engineering equipment. The control platform uses PLC+inverter The open -type control structure can complete the tr--ning tr--ning tr--ning tr--ning tr--ning tr--ning tr--ning tr--ning tr--ning for teaching and research inverter and constant pressure water supply technology. School electrical automation, building automation, building electrical, intelligent architecture and other professional comprehensive tr--ning equipment.

Second, systemic characteristics

The control platform adopts an open control structure of PLC+inverter, providing configuration software and PLC development environment, which allows students to design control solutions themselves and have strong flexibility.

The control platform has multiple protection mechanisms such as heat overload protection, overcurrent protection, leakage protection, grounding protection, ground frequency and frequency conversion link control.

The control system can simulate the real water supply system. There are two control methods: automatic control and manual control. When the automatic control f--ls, the system runs by manual control.

All control objects use st--nless steel and organic glass devices to ensure that they are not rust and are not easy to aging. Simulating the six -story building to the water system, which has two types of waterway models: living water system and fire water system; the power system consists of four water pumps, two of which Conventional inverter cycle pump, a dormant pump, a fire pump, can simulate conventional living water supply systems, fire water supply systems, and small traffic water supply systems at night, and can vividly simulate the typical structure of the dr--nage system for the building.
