Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figures 1-4A pipeline operation model teaching aid includes a base 1, a protective door 2, a handle 3, a protective sleeve 4, an observation board 5, a water tank 6, a submersible pump 7, a water inlet pipe 8, a flow meter 9, a pipeline pump 10, a gate valve 11, an air valve 12, a ball valve 13, a butterfly valve 14, a return pipe 15, and a drain pipe 16. A protective door 2 is hinged to the front of the base 1, the handle 3 is fixedly connected to the protective door 2, and the protective sleeve 4 is fitted onto the handle 3. The protective sleeve 4 is typically made of a soft material to provide a better grip. The observation board 5 is embedded in the back of the base 1 and is made of a transparent or semi-transparent material to observe the internal operation of the model teaching aid, such as water flow direction and equipment status. The water tank 6 is installed inside the base 1. Equipped with a submersible pump 7, which is responsible for drawing water from the water tank 6, the flow meter 9, pipeline pump 10, gate valve 11, air valve 12, ball valve 13 and butterfly valve 14 are arranged sequentially from left to right on the top of the water tank 6. The various modules are connected by pipes and flanges to form an integrated pipeline model with a compact structure, strong integrity, and support for disassembly and assembly operations. The flow meter 9 is connected to one end of the water supply pipe 8, and the other end of the water supply pipe 8 is connected to the outlet of the submersible pump 7 for water flow transportation. The butterfly valve 14 is connected to one end of the return water pipe 15. The other end of the return water pipe 15 can be connected to the water tank 6 to realize water recycling, or the water can be discharged directly. A drain pipe 16 is provided on one side of the bottom of the platform 1 for drainage operations inside the platform 1.

[0025] The pipeline operation model teaching aid consists of various components, including a water tank 6, a submersible pump 7, a water supply pipe 8, a flow meter 9, a pipeline pump 10, a gate valve 11, an air valve 12, a ball valve 13, a butterfly valve 14, a return water pipe 15, and a drain pipe 16, forming a complete pipeline system. By starting the submersible pump 7, water is supplied to each module to simulate the real pipeline operation environment. This allows trainees to intuitively see and understand the pipeline layout, the operating principles of the equipment, and the interrelationships between the various modules. In addition, the modules are designed with flange connections, allowing trainees to disassemble and reassemble the various parts, which facilitates demonstrations in teaching and enhances practical operation skills.

[0026] The specific usage method of the pipeline operation model teaching aid is as follows:

[0027] 1. Fault Simulation: The teaching aids can simulate fault conditions in pipeline operation, such as leakage and blockage, to help trainees understand the causes and solutions to faults and improve their ability to deal with emergencies.

[0028] 2. Safety Demonstration: Safety is of paramount importance in pipeline operation. The teaching aids can simulate various safety risks and emergencies to help trainees understand how to take the correct response measures in emergency situations.

[0029] 3. Skills training: For personnel engaged in pipeline operation, maintenance and management, mastering relevant skills is crucial. Teaching aids can simulate various operating scenarios and fault conditions to help trainees master the necessary skills and methods, and improve work efficiency and quality.

[0030] 4. Skills assessment: The teaching aids can also be used for skills assessment and evaluation. By simulating actual working scenarios and fault conditions, the students' skill levels can be objectively evaluated and assessed.

[0031] Example 2: Based on Example 1, please refer to... Figure 4 and Figure 5 It also includes a buffer seat 17, a slider 18, a label plate 19, and a light strip 21. Each valve, flow meter 9, and pipeline pump 10 located on the platform 1 is snapped with a buffer seat 17 at its bottom to provide effective support. The label plate 19 is located on the front side of the buffer seat 17, and the light strip 21 is located on the label plate 19 to provide sufficient illumination so that the information on the label plate 19 can be clearly seen in low light conditions. The slider 18 is fixed to the bottom of the buffer seat 17. The top of the water tank 6 is designed with a groove 20 that matches the position of each module. The slider 18 can slide back and forth along this groove 20 to realize the sliding connection between the model teaching aid and the platform 1.

[0032] When using the model teaching aids, the name, number, function, and other information of the model teaching aids are marked on the label plate 19 for easy identification and management. When the model teaching aids are disassembled and reassembled, the buffer seat 17 provides stable support for the model teaching aids, ensuring that they remain stable during use and preventing measurement errors or equipment failures caused by shaking. By moving the buffer seat 17, the slider 18 slides back and forth along the slide groove 20, increasing the flexibility of the model teaching aids and making it convenient for teachers and students to quickly disassemble and reassemble them during the teaching process. At the same time, the model teaching aids can be easily removed from the base 1 for easy cleaning, maintenance, or replacement of parts, reducing maintenance time and costs.

[0033] Please see Figure 6 It also includes guide rods 22, floats 23, sensing blocks 24, sensors 25, and alarms 26. Guide rods 22 are provided around the inside of the water tank 6. The floats 23 are slidably mounted on the guide rods 22 to detect the water level. The left end of the floats 23 is provided with a sensing block 24. The corresponding position of the sensor 25 is provided at the bottom of the water tank 6. The sensing block 24 and the sensor 25 are triggered to operate through contact. The alarm 26 is installed on the top of the water tank 6 to emit an audible alarm.

[0034] The float 23 moves up and down with the water level in the water tank 6, monitoring the water level in the water tank 6 in real time. When the water level drops to the preset low water level threshold, the float 23 descends and drives the sensor block 24 to contact the sensor 25, thereby triggering the alarm 26. The alarm 26 then sounds an alarm, indicating that the water level is too low and water needs to be added in time to avoid damage or shutdown of the system due to lack of water.

[0035] It should be understood that the above description is for illustrative purposes only and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
