DETAILED DESCRIPTION

[0017] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0018] A blowout preventer model of this embodiment is shown in the attached Figure 1 and 2 , including a gate assembly 1, a power cylinder assembly 2 and a shell 3. The power cylinder assembly 2 is arranged on both sides of the shell 3. The gate assembly 1 is arranged in the shell 3 and connected to the power cylinder assembly 2. The shell 3 is provided with a wellhead channel 31 running through the upper and lower ends. The power cylinder assembly 2 is used to drive the gate assembly 1 to move closer to or away from each other. The shell 3 is made of transparent material.

[0019] In this embodiment, a blowout preventer model is formed by setting a gate assembly 1, a power cylinder assembly 2 and a housing 3, and the housing 3 is made of a transparent material, through which the internal structure and the action of the blowout preventer can be observed, so that students, engineers, technicians and other personnel can better understand and master the structure and working principle of the blowout preventer. This learning method is more intuitive and practical. The blowout preventer model of this embodiment can also be used to simulate the situation of a blowout accident, thereby helping people better understand the hazards of a blowout accident and learn how to correctly operate and maintain a blowout preventer to prevent the occurrence of a blowout accident.

[0020] Preferably, the power cylinder assembly 2 includes a plurality of drive units 21, which are arranged on both sides of the housing 3, and the gate assembly 1 includes a locking gate 22 and a sealing gate 23 arranged up and down, and the locking gate 22 and the sealing gate 23 are respectively connected to the telescopic ends of the drive unit 21. The drive unit 21 is arranged to drive the locking gate 22 and the sealing gate 23 to close or separate, so that the driving unit 21 connected to the sealing gate 23 can be controlled to simulate that when the wellhead pressure increases, the sealing gate 23 is automatically and tightly attached to the wellhead channel 31 to form a barrier, thereby preventing a blowout accident from occurring. And by controlling the drive unit 21 connected to the locking gate 22, it is simulated that the wellhead channel 31 is completely closed in an emergency to prevent the wellhead from being out of control.

[0021] Furthermore, the drive unit 21 includes a cylinder shell 211, a piston block 212, a push rod 213 and an electric push cylinder 214. The cylinder shell 211 is arranged on both sides of the shell 3, the electric push cylinder 214 is arranged in the shell 3, one end of the piston block 212 is connected to the telescopic end of the electric push cylinder 214, and the other end of the piston block 212 is connected to the push rod 213. The push rod 213 is used to connect to the locking gate plate 22 or the sealing gate plate 23.

[0022] The electric push cylinder 214 is used as a power source to replace the hydraulic system in the actual blowout preventer, thereby realizing the control of the approach or separation action of the locking gate 22 and the sealing gate 23, eliminating the complex hydraulic system, making the model more concise, easy to maintain, and reducing costs. At the same time, the electric drive method also has the advantages of fast response speed and high control accuracy. By controlling the electric push cylinder 214, the precise control of the gate opening and closing speed is achieved to simulate the action of the blowout preventer under different working conditions. In addition, in order to facilitate display, auxiliary equipment such as indicator lights and display screens can be added. By lighting the indicator lights, the working status (open or closed) of the gate can be more intuitively displayed, and the display screen can display relevant operating parameters and working status information. The intuitiveness of the display of the structure and working principle of the blowout preventer is further improved.

[0023] Furthermore, the cylinder shell 211 is made of a transparent material. In order to restore the actual action of the blowout preventer, a piston block 212 is also provided in the cylinder shell 211. The electric push cylinder 214 pushes the piston block 212 to move, simulating the position change of the piston block 212 when the hydraulic system is in effect, and showing the working principle of the blowout preventer in more detail. The cylinder shell 211 made of a transparent material is convenient for showing the position of the piston block 212.

[0024] Preferably, the end surface of the locking gate 22 is provided with a first seal 221, and the end surface of the sealing gate 23 is provided with a second seal 231. By respectively providing the first seal 221 and the second seal 231 on the end surface of the locking gate 22 and the end surface of the sealing gate 23, the wear of the seals of the blowout preventer under long-term operation can be simulated, which is convenient for guiding personnel to perform regular maintenance, including cleaning oil stains, checking the wear of seals, replacing damaged parts, etc.

[0025] Preferably, a hydraulic valve model 4 and a hydraulic pipeline model are also included. The hydraulic valve model 4 is arranged on the front side of the housing 3, and the hydraulic pipeline model is connected to the hydraulic valve model 4 and the cylinder housing 211 respectively. The hydraulic valve model 4 is arranged on the front side of the housing 3 of the blowout preventer model, so that the trainees can intuitively understand the working principle of the hydraulic valve and its role in the blowout preventer system. By setting up the hydraulic pipeline model, not only the flow path of the hydraulic oil is demonstrated, but also the understanding of the mutual cooperation between the hydraulic system and the blowout preventer can be helped.

[0026] Furthermore, the outside of the hydraulic pipeline model is wrapped with a light bar. By wrapping a layer of flexible LED light bar on the outside of the hydraulic pipeline model. The color and flashing mode of the light bar can be programmed through the controller. For example, when the hydraulic oil flows in the pipeline, the light bar can emit blue light or green light to indicate the flow, to simulate the flow state of the hydraulic oil. When the simulated hydraulic system pressure changes or reaches a certain threshold, the color or flashing frequency of the light bar can change accordingly to provide instant visual feedback, so that trainees can clearly observe and understand the working status of the hydraulic system more intuitively, thereby helping trainees to have a deeper understanding of the working principle and operation process of the blowout preventer.

[0027] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
