I. Overview 

The overall design of the water dr--nage object model is designed with aluminum profile framework and mesh plate. It is m--nly installed on the steel frame base for dr--nage pipelines and has the characteristics of open type. , Sewage treatment system and control system six parts.

2. Functional characteristics:

1. St--nless steel water plate, cold and hot water faucet, simulate two -story building, mesh -type room, and 4 household water terminals

2. Pool: Made of st--nless steel, enter four roads all the way, provide constant water sources to each system, set up floating ball switches and exhaust holes to ensure the water level of the pool.

3. Three -phase water pump: two units, provide motivation for the constant pressure water supply system

4. Single -phase water pump: three units, providing power for the heating/heating system, the --r pressure supply system and the water pump water tank combined with the water pump water tank

5. Pressure transmitter: detect the current pressure value in the water pipe of the constant pressure water supply system, you can detect 0 ～ 400kPa pressure

6. Membership box pressure gauge: detect the current pressure value in the water pipe of the water supply system in the water supply system, you can detect 0 ～ 400kPa pressure

7. High -level water tank: water pump water tank water supply system water supply system, water pump water tank combined with water supply tr--ning with water sources to the user terminal, set up high and low water level switches to achieve automatic start and stop of water pumps

8. Pneumatic water tank: water pressure supply system water storage device, providing pressure water source to user terminal during the tr--ning of --r pressure supply system

9. High and low pressure switch: detect the current pressure of the water supply water supply system pipeline, provide signals for the start and stop of the pump

10. Pressure gauge: detect the current pressure of the pipeline of the --r pressure supply system, you can detect 0-1MPa pressure

11. Water heater: Provide heat sources for the heating/heating system, built -in temperature detection and control circuit

12, heat sink: production of steel pipes and copper pieces, transmit heat in hot water to indoor --r

M--n technical features:

The punching machine and feeding experimental device are suitable for mechanical design experimental teaching, which has distinctive characteristics.

(1) It corresponds to the m--n content of the course, including various common institutions and universal machinery parts;

(2) Have the practical background of the engineering, the use function is obvious;

(3) Good intuition;

(4) Moderate structural complexity, and the transmission scheme and structure are novel. Through the analysis of the transmission scheme and structure of the device, students can grasp the basic requirements of mechanical system motion solutions and structural design, and cultivate the design capacity, structural design ability and innovative awareness of the mechanical system motion scheme.

(5) Virtual simulation teaching system

Machinery tr--ning security education virtual simulation software: This software is developed based on UNITY3D. The software is in the form of three -dimensional roaming. It can be moved by keyboard control. The direction of the mouse control lens is equipped with mechanical safety distance experiments, mechanical safety protection device experiments, mechanical safety protection design Basic assessment and experiments, the three -dimensional roaming screen uses arrows and footprint patterns to move to the experimental location. The circle around the mechanical object shows a working radius, and the experimental process is accompanied by a three -dimensional robot dialog box reminder.

A. Mechanical safety distance experiment content includes a safe distance experiment to prevent the upper and lower limbs from touching the dangerous area (the height and opening of the two fences in the inside). After choosing to enter, the GB23821-2009 "Mechanical Security to prevent the upper and lower limbs from touching the dangerous area of the dangerous area. "Safety distance" requires that the error demonstration: After the experimental process is harmed by the working radius of the human body entering the mechanical object, the blood -colored picture and voice reminder receive mechanical damage, return to the original position and perform the next experiment. The final step is the correct practice.
