Description

Technical Field

[0001] This utility model relates to the field of gas turbine equipment, specifically a gas turbine DCS load control device. Background Technology

[0002] The load control equipment of a gas turbine DCS (Distributed Control System) is a series of devices and systems used to control the load of a gas turbine, mainly composed of the following parts:

[0003] The controller is the core of the load control equipment and usually uses an advanced microprocessor or digital signal processor. It receives signals from various sensors, including parameters such as the speed, temperature, and pressure of the gas turbine, as well as set values ​​from the operator or instructions from external systems. Then, according to the preset control algorithm and logic, it processes and analyzes these signals to calculate the control signal to be output in order to regulate the load of the gas turbine.

[0004] Sensors are used to monitor the operating parameters of the gas turbine in real time, providing accurate data to the controller. For example, temperature sensors are used to measure the gas turbine's intake and exhaust temperatures; pressure sensors are used to monitor the gas turbine's intake and combustion chamber pressures; and speed sensors are used to measure the gas turbine's shaft speed. The accuracy and reliability of these sensors directly affect the accuracy and stability of load control.

[0005] Actuators: Based on the control signals output by the controller, they perform corresponding actions to adjust the load of the gas turbine. Common actuators include fuel regulating valves and inlet guide vane actuators. Fuel regulating valves control the output power of the gas turbine by adjusting the amount of fuel entering the combustion chamber. Inlet guide vane actuators change the airflow into the gas turbine by adjusting the angle of the inlet guide vanes, thereby affecting the combustion process and output power.

[0006] The human-machine interface control panel facilitates operators to monitor and intervene in the load control process, and the communication network is used to realize data transmission and information sharing between various devices. Through the coordinated work of these devices, the gas turbine DCS load control equipment can accurately control the load of the gas turbine according to factors such as grid demand and process requirements, ensuring the safe, stable and efficient operation of the gas turbine.

[0007] Taking the human-machine interface control screen in the DCS load control equipment of gas turbine as an example, when the equipment is idle, dust can easily accumulate on the control screen. During subsequent operations, the dust will make the surface of the display screen no longer smooth and flat, and light will be scattered and refracted on its surface, thereby reducing the clarity and contrast of the screen, making the displayed images, text and other content blurry, and making it difficult for operators to read information accurately. Utility Model Content

[0008] The purpose of this invention is to provide a gas turbine DCS load control device to solve the defects mentioned in the background art.

[0009] To achieve the above objectives, a gas turbine DCS load control device is provided, including an interactive control panel. A storage base is installed at the bottom of the interactive control panel, and a mounting bracket is fixedly installed at the bottom of the storage base. A drive lifting assembly is installed on the back of the storage base, and a limit rail is fixedly installed on the top of the storage base. A gear is provided on the drive lifting assembly, and the gear is located on one side of the interactive control panel. A synchronous wheel A is installed on the shaft of the gear, and the shaft of the synchronous wheel A is movably connected to the side wall of the limit rail through a bearing seat.

[0010] Preferably, the interactive control screen is driven to rise and fall on the storage base by a driving lifting component. The front of the storage base is provided with a protective panel, which is a rectangular structure made of acrylic material. The interactive control screen moves downward and is stored inside the storage base.

[0011] Preferably, limit strips are fixedly installed on both sides of the interactive control screen, and two sets of limit rails are set on the top of the storage base. Limit channels are opened inside the two sets of limit rails, and the dimensions of the limit strips and limit channels are compatible.

[0012] Preferably, the limiting strip is inserted into the inside of the limiting track, and a rack is fixedly provided on the outside of the limiting strip. The rack and the gear are matched in size and mesh with each other.

[0013] Preferably, the drive lifting assembly includes a rack, a gear, a synchronous pulley A, a synchronous belt, a bearing housing, a drive motor, a synchronous pulley B, and a fixed base; the fixed base is U-shaped, and its two ends are respectively fixedly installed on both sides of the back of the storage base.

[0014] Preferably, two sets of drive motors are respectively installed on the fixed base. A synchronous pulley B is fixedly installed at the end of the output shaft of the drive motor. A synchronous belt is sleeved on the synchronous pulley B. A synchronous pulley A is installed on the side of the synchronous belt away from the synchronous pulley B. The synchronous pulley A and the synchronous pulley B are driven by the synchronous belt.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model utilizes a driving lifting component to move the interactive control screen downwards and store it inside the storage base. This effectively prevents dust from falling and accumulating on the surface of the interactive control screen, preventing dust from entering the screen and affecting display effects and performance, reducing the failure rate caused by dust, and extending the screen's lifespan. After being stored, the interactive control screen is protected by the storage base, reducing the risk of accidental scratches or collisions from external objects, preventing damage such as scratches and cracks, and maintaining the integrity of the screen's appearance and function. During subsequent operations, dust prevents the display surface from becoming uneven, causing light scattering and refraction, which would reduce screen clarity and contrast, allowing operators to accurately read information.

[0017] 2. This utility model uses a gear and rack meshing connection to drive the interactive control screen to lift and lower, while simultaneously adjusting the height of the interactive control screen. Different operators have different heights, and through height adjustment, whether tall or short, people can adjust the interactive control screen to a suitable height, so that their arms are in a natural and comfortable state during operation, without excessive stretching or bending over, thereby improving the convenience and comfort of operation and reducing physical fatigue caused by prolonged uncomfortable operation.

[0024] Please see Figure 1-5This utility model provides a gas turbine DCS load control device, including an interactive control screen 5, a storage base 2 installed at the bottom of the interactive control screen 5, a mounting bracket 1 fixedly installed at the bottom of the storage base 2, a drive lifting assembly 6 installed on the back of the storage base 2, a limit rail 4 fixedly installed on the top of the storage base 2, a gear 62 installed on the drive lifting assembly 6, the gear 62 is located on one side of the interactive control screen 5, a synchronous wheel A63 is installed on the shaft of the gear 62, and the shaft of the synchronous wheel A63 is movably connected to the side wall of the limit rail 4 through a bearing seat 65.

[0025] Working Principle: When the interactive control screen 5 is idle, to prevent a large amount of dust from falling onto its surface, the lifting component 6 drives the interactive control screen 5 downwards, storing it inside the storage base 2. This effectively prevents dust from falling and accumulating on the surface of the interactive control screen 5, preventing dust from entering the screen and affecting display effects and performance, reducing the failure rate caused by dust, and extending the screen's lifespan. After being stored, the interactive control screen 5 is protected by the storage base 2, reducing the risk of accidental scratches or collisions from external objects, preventing scratches, cracks, and other damage to the screen, and maintaining the integrity of the screen's appearance and function; making the overall space... The interactive control screen 5 is more aesthetically pleasing and tidy. When not in use, it can be stored away, preventing it from being exposed and affecting the cleanliness of the environment. This is especially beneficial in places where aesthetics are important, such as conference rooms and exhibition halls, as it enhances the overall visual effect. Storing the interactive control screen 5 also prevents accidental operation due to accidental touches, avoiding situations such as accidentally turning on the device or changing settings, and ensuring the device remains in a stable standby state when idle. In brightly lit environments, an idle interactive control screen 5 may reflect light, causing glare and affecting the vision of those around it. Storing it away reduces this light interference, making the environment more comfortable.

[0026] When the interactive control screen 5 is raised or lowered, the limiting strips 51 on both sides are inserted into the inside of the limiting rail 4, which can limit and guide the interactive control screen 5 during the raising and lowering process, ensuring the stability of the interactive control screen 5 during the raising and lowering process, preventing it from tilting, and preventing the rack 61 and gear 62 from disengaging.

[0027] The lifting mechanism of the interactive control screen 5 is achieved through two sets of synchronously operating lifting drive components 6. Specifically, the external switch of the drive motor 66 is activated, and the output shaft of the drive motor 66 drives the synchronous pulley B661 to rotate. The synchronous pulley B661 drives the synchronous pulley A63 to rotate through the synchronous belt 64. The synchronous pulley A63 drives the gear 62 to rotate. The gear 62 meshes with the rack 61, thereby lifting the interactive control screen 5. At the same time, the height of the interactive control screen 5 can be adjusted. Different operators have different heights. Through height adjustment, whether tall or short, people can adjust the interactive control screen 5 to a suitable height, so that their arms are in a natural and comfortable state during operation, without excessive stretching or bending over. This improves the convenience and comfort of operation and reduces physical fatigue caused by prolonged uncomfortable operation.

[0028] As a preferred implementation, the interactive control screen 5 is driven to rise and fall on the storage base 2 by the drive lifting component 6. The front of the storage base 2 is provided with a protective panel 3, which is a rectangular structure made of acrylic material. The interactive control screen 5 moves downward and is stored inside the storage base 2.

[0029] As a preferred implementation, limit strips 51 are fixedly installed on both sides of the interactive control screen 5, and two sets of limit rails 4 are set on the top of the storage base 2. Limit channels are opened inside the two sets of limit rails 4, and the size of the limit strips 51 and the limit channels are compatible.

[0030] In a preferred embodiment, the limiting strip 51 is inserted into the inside of the limiting track 4, and a rack 61 is fixedly provided on the outside of the limiting strip 51. The rack 61 and the gear 62 are matched in size and are meshed together.

[0031] In a preferred embodiment, the drive lifting assembly 6 includes a rack 61, a gear 62, a synchronous pulley A63, a synchronous belt 64, a bearing housing 65, a drive motor 66, a synchronous pulley B661, and a fixed base 67; the fixed base 67 is U-shaped, and its two ends are fixedly mounted on the back sides of the storage base 2.

[0032] In a preferred embodiment, two sets of drive motors 66 are respectively installed on the fixed base 67. A synchronous pulley B661 is fixedly installed at the end of the output shaft of the drive motor 66. A synchronous belt 64 is sleeved on the synchronous pulley B661. A synchronous pulley A63 is installed on the side of the synchronous belt 64 away from the synchronous pulley B661. The synchronous pulley A63 and the synchronous pulley B661 are driven by the synchronous belt 64.

[0033] The method of controlling the gas turbine DCS load through the interactive control panel 1 is as follows: The interactive control panel 1 displays in real-time key operating parameters of the gas turbine, such as current load, speed, temperature, and pressure, as well as the status information of related equipment, allowing operators to intuitively understand the gas turbine's operating status. Operators can input load setpoints on the interactive control panel 1, which are then transmitted to the gas turbine's control system via the DCS system. This allows for adjustments to fuel supply, air intake, etc., to achieve precise control of the gas turbine load. The interactive control panel 1 is equipped with various control buttons and operation menus, such as start, stop, load increase, and load decrease buttons. Operators can click the corresponding buttons according to actual needs. After receiving the operation command, the DCS system automatically executes the corresponding control action, achieving flexible control of the gas turbine load. When the gas turbine operating parameters exceed the set range or a fault occurs, the interactive control panel 1 will promptly issue alarm information, alerting operators through text, sound, or flashing lights, and providing corresponding fault handling prompts to help operators make quick decisions and ensure the safe and stable operation of the gas turbine.
