Description

Technical Field

[0001] This invention relates to the technical field of impeller feeder control, and in particular to a wireless control system for a power plant impeller feeder. Background Technology

[0002] Thermal power plants generate electricity by burning fuel (such as coal) to heat water and produce steam. The steam then drives a steam turbine. To ensure a continuous supply of steam, a rotary coal feeder is needed to continuously transport coal.

[0003] The existing impeller feeder power line carrier control system disclosed in patent CN204965737U and the impeller feeder drive cable device disclosed in patent CN220642139U can both achieve continuous coal conveying. However, during use, it was found that because the impeller feeder is a moving device and operates in a dusty environment, and is located in a coal unloading trench several meters underground, with the distance between the trench and the control room typically ranging from 1000 to 2000 meters, the workload for staff is significant. While transmitting signals via cable and allowing staff to control the feeder from the control room reduces workload, the cables frequently rub against the ground and dust, often bending and causing control interruptions, affecting coal feeding efficiency and resulting in poor practicality. Therefore, a wireless control system for power plant impeller feeders is urgently needed to address these issues. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a wireless control system for a power plant's impeller feeder. This system facilitates remote wireless control of the impeller feeder by continuously setting multiple wireless transceiver units along its moving line. Furthermore, the proximity of the wireless transceiver units to the control module significantly reduces wireless communication latency. Even in the event of a signal transmission line failure, remote control can still be achieved through multiple sets of wireless transceiver units, ensuring the impeller feeder's normal operation for a short period. Additionally, in the event of communication interruption or if personnel fail to provide timely new control commands, a neural network model can be used to control the impeller feeder, maintaining its normal operation and improving its operational stability.

Finally, the air is sprayed out by multiple sets of nozzles to clean the dust on the top of multiple sets of storage boxes, ensuring stable transmission of wireless signals. In addition, during the exhaust process, the heat of the wireless transceiver unit is dissipated by multiple sets of heat dissipation fins and carried away by the flowing air, thus cooling the wireless transceiver unit and improving the practicality of cleaning the heat dissipation module.

The booster cylinder is mounted on a storage tank, the piston is slidably mounted in the booster cylinder, and the telescopic motor is fixedly mounted at the bottom of the booster cylinder, with the top end of the telescopic motor connected to the bottom end of the piston. By retracting the telescopic motor, the piston slides downward, drawing some air from the storage tank into the booster cylinder. Then, by rapidly extending the telescopic motor, the piston slides upward, quickly expelling the air from the booster cylinder into the storage tank. Subsequently, the air sequentially enters the rotating pipe and multiple sets of jet nozzles. The rapidly flowing air opens the multiple sets of nozzles, or the rapidly ejected air from the multiple sets of nozzles causes the rotating pipe to rotate, thereby improving the practicality of the unblocking mechanism.

[0014] Preferably, a one-way valve is provided at the top of the support pipe to prevent air from the air storage box from entering the support pipe, thereby improving the practicality of the unblocking mechanism.

A wireless control system for an impeller coal feeder in a power plant as claimed in claim 1, characterized in that: The data storage module comprises: Management unit: centrally controls the storage unit and the random comparison unit, and presets the storage period of the storage unit; Storage unit: There are three groups, and the three groups of storage units are located in the main control module, the slave control module and the data analysis module respectively. The three groups of storage units store the same data, including the system operation data, the staff operation data and the impeller coal feeder operation data. This storage method prevents data loss. When the data in the three groups of storage units need to be manually deleted or modified, three managers need to authorize and confirm at the same time and operate on site; Random comparison unit: Regularly randomly select some of the same data from the three groups of storage units for comparison to ensure the sameness of the data and prevent data tampering. When the system or impeller coal feeder fails, it is convenient to trace the cause of the failure through the stored data.

6. A wireless control system for an impeller coal feeder in a power plant as claimed in claim 1, characterized in that: The data analysis module includes: Data acquisition unit: acquires the data received daily from the control module and the detection results of the detection unit as analysis data of the deep learning analysis unit, and sends the data to the deep learning analysis unit; Deep learning analysis unit: When the impeller coal feeder is running, if the main control module does not send commands to the slave control module for a long time, the PyTorch framework and recurrent neural network are used to analyze and process the received data through the trained qualified model, and send commands to the slave control module to achieve short-term automatic control of the impeller coal feeder to ensure the normal supply of coal, and at the same time the control management module sends an alarm; Database: Stores the training data of the deep learning analysis unit.

7. A wireless control system for an impeller coal feeder in a power plant as claimed in claim 1, characterized in that: The control management module includes: Identity verification unit: Verify the identity information of the login personnel to ensure the security of the system; Centralized control unit: centrally controls the main control module, signal transmission module, slave control module, data storage module, data analysis module and cleaning and heat dissipation module; Alarm unit: When an abnormal problem occurs in the system or impeller coal feeder, an alarm will be issued in the form of a pop-up window to prompt the staff.

8. A wireless control system for an impeller coal feeder in a power plant as claimed in claim 1, characterized in that: The cleaning and heat dissipation module comprises an air compressor (1), a plurality of support tubes (2), a plurality of storage boxes (3), a plurality of heat dissipation fins (4), a plurality of rotating tubes (5), a plurality of jet tubes (6), a plurality of nozzles (7) and a plurality of dredging mechanisms.
