DETAILED DESCRIPTION

[0045] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0046] Embodiment 1: Figures 1 to 11 As shown, a hydropower station unit control device according to an embodiment of the present invention includes a cabinet 1, wherein a control component 4 is arranged inside the cabinet 1, and the control component 4 includes an output sharing platform 37, a processing unit 38, a data sharing platform 39, an electric parameter calculation unit 40 and a collection unit 41;

[0047] The acquisition unit 41 acquires data and transmits it to the data sharing platform 39 through a data acquisition channel;

[0048] The data sharing platform 39 realizes data transmission with the processing unit 38 through a data exchange channel;

[0049] The processing unit 38 transmits the data to the control output sharing platform 37 through the control output command channel;

[0050] The electric parameter calculation unit 40 exchanges data with the data sharing platform 39 through a data exchange channel;

[0051] The data sharing platform 39 is also connected to the remote network communication unit and the human-machine interface UI data respectively.

[0052] When working, the output sharing platform 37 uses an independent processor, and the processor realizes external control output according to the control command. All logical function modules control all external control output interfaces by sending control commands to the output sharing platform 37. Through the output sharing platform 37, all logical function modules can realize cross-complementarity of functions, and there is no need to add additional duplicate control output interfaces;

[0053] The data sharing platform 39 uses an independently developed embedded database system. The system divides the data into instantaneous sampling data, real-time operation data, historical curve data, event and alarm file data. According to different update speed requirements and storage time requirements, the data is stored on different storage media (such as RAM, FRAM and FLASH);

[0054] The data sampling channel samples the 16-bit parallel bus communication mode. The data acquisition channel is the data channel connecting the data sharing platform 39 with each acquisition unit 41. The characteristics of this channel are large data volume, fast communication speed, and high real-time requirements. For example, the voltage and current data acquisition unit 41 samples the voltage and current instantaneous data of 9 channels, and the sampling rate is 25,600 data samples per channel per second. Therefore, in order to ensure the rapid communication of big data, the data sampling channel adopts the 16-bit parallel bus communication mode. Each acquisition unit 41 adopts a priority time-sharing multiplexing scheme to allocate the parallel bus occupancy time. The parallel bus is divided into 10 time slices in total. Due to the maximum data volume of voltage and current instantaneous data, 8 of the time slices are occupied. The real-time requirements of the switching quantity are high, and 1 of the time slices is occupied. Other modules share the remaining 1 time slice. The data sharing platform 39 and each acquisition unit 41 adopt a master-slave response communication mode. The shared platform processor is the communication host of the data acquisition channel, which performs time allocation processing and initiates data communication;

[0055] The data exchange channel uses a high-speed SPI serial peripheral interface. The data exchange channel is the channel for each logic processing unit 38 to exchange data with the data sharing platform 39. It needs to take into account both real-time and big data requirements. According to this requirement, the system uses a high-speed SPI serial peripheral interface. The SPI bus system is a synchronous serial peripheral interface. In point-to-point communication, the SPI interface does not require addressing operations, and it is full-duplex communication, which is simple and efficient. In a system with multiple slave devices, each slave device requires an independent enable signal. This system treats each logic processing unit 38 as a slave device, and each logic processing unit 38 has an independent enable signal. The shared platform processor acts as the host to initiate data exchange with each module. Like the data acquisition channel, each logic processing unit 38 uses a priority time-sharing multiplexing scheme to allocate the occupancy of the SPI bus. The processor of the data sharing platform 39 acts as the SPI communication host to allocate time and initiate data exchange;

[0056] The coordinated work of the above-mentioned equipment simplifies the complexity of the system, ensures data consistency, reduces the failure rate, improves the safety and reliability of small hydropower station operation, reduces manual work intensity, and improves work efficiency.

[0057] The acquisition unit 41 includes a voltage and current data acquisition unit 41, a water level acquisition unit 41, a switch quantity acquisition unit 41 and a temperature acquisition unit 41; when working, each acquisition unit 41 collects data related to the operating environment of the hydropower station through the corresponding acquisition equipment, and transmits the collected data to the data sharing platform 39 in real time, so as to issue control instructions according to the relevant data.

[0058] The processing unit 38 includes a speed regulator processing unit 38, a protection processing unit 38, a quasi-synchronous processing unit 38, an excitation processing unit 38 and an intelligent control logic processing unit 38; when working, the quasi-synchronous processing unit 38 can realize part of the protection function, the excitation processing unit 38 can realize part of the speed regulator function, etc.

[0059] It also includes a heat dissipation component, which includes a heat dissipation fan 2 and a shell 5. The heat dissipation fan 2 is fixedly installed on the side wall of the cabinet 1, and the shell 5 is fixedly installed on the inner side of the side wall of the cabinet 1.

Side panels 17 are respectively fixed at both ends of the shell 5, and a support plate 16 is fixed on the inner side of the side panel 17. The upper and lower ends of the support plates 16 on both sides are rotatably installed with a rotating drum 15, and the outer sides of the upper and lower rotating drums 15 are sleeved with filter cotton belts 14. An air outlet 18 is provided between the support plate 16 and the side plate 17. When in operation, the hot air inside the cabinet 1 is discharged through the cooling fan 2, and the cold air is sucked in through the air inlet 3. Then the air enters the middle of the filter cotton belt 14 and is discharged into the cabinet 1 from the air outlets 18 on both sides, thereby accelerating the air circulation inside the cabinet 1 and cooling the inside of the cabinet 1. In addition, by installing the filter cotton belt 14 inside the shell 5 for air filtering, dust particles in the air can be effectively blocked from entering the cabinet 1, preventing dust from being deposited on the equipment, thereby protecting the equipment from damage.

[0060] The side plate 17 is provided with a driving assembly for driving the filter cotton belt 14 to rotate, and the driving assembly includes a fixed cylinder 24, and the fixed cylinder 24 is arranged in the middle of the rotating cylinder 15 located below, and there is a gap between the two ends of the fixed cylinder 24 and the side plate 17, and a movable rod 19 is provided in the middle of the two ends of the fixed cylinder 24, and the movable rod 19 movably passes through the through hole provided on the side plate 17, and an arc-shaped guide groove 30 is provided on the side wall of the movable rod 19, and a guide block adapted to the arc-shaped guide groove 30 is fixed on the side wall of the through hole, and vertical plates 8 are provided on the outer sides of the side plates 17 on both sides, and the ends of the movable rod 19 are rotatably connected to the side walls of the vertical plates 8, and a rotating shaft 20 is rotatably installed on the side plate 17 and located above the movable rod 19, and a gear shaft 22 is fixed on the rotating shaft 20 and on one end of the outer side of the side plate 17, and a rotating disk 23 is fixed on the rotating shaft 20 and on one end of the inner side of the side plate 17, and movable A movable groove, in which a tooth 26 is slidably installed, and the end of the tooth 26 is set to a right-angled trapezoid shape, a spring 21 is fixed inside the movable groove to reset the tooth 26, and a plurality of groups of protrusions 25 are evenly fixed on the inner wall of the end of the rotating drum 15 located below, and the protrusions 25 are adapted to the tooth 26. A spur gear 21 is fixed to one end of the movable rod 19 close to the vertical plate 8, and the spur gear 21 is meshed with the gear shaft 22. A pull rope 9 is fixed between the tops of the vertical plates 8 on both sides. A disc 10 is rotatably installed on the inner wall of the cabinet 1 and located above the shell 5 through the mounting shaft. A lever 11 for driving the pull rope 9 to move upward is fixed at the edge of the disc 10. The mounting shaft is connected to the driving shaft of the cooling fan 2 through a helical gear transmission group 7. A stop rod 12 for limiting the movement of the pull rope 9 is fixed on both sides of the disc 10, and a spring 13 for resetting the vertical plate 8 is fixed on the side walls of the side plates 17 on both sides.

[0061] During operation, the cooling fan 2 rotates and transmits power to the mounting shaft through the bevel gear transmission group 7, thereby driving the disc 10 to rotate. When the disc 10 drives the lever 11 to move from the lowest position to the highest position, the pull rope 9 is pulled upward by the lever 11, and the pull rope 9 is prevented from moving upward as a whole by the blocking rod 12, thereby causing the vertical plates 8 on both sides to move toward the middle under the traction of the pull rope 9. The vertical plates 8 simultaneously push the movable rods 19 on both sides to move toward the middle of the fixed cylinder 24. At this time, the spring 13 is compressed, and the movable rod 19 can rotate while moving horizontally along the through hole on the side plate 17 through the cooperation of the arc guide groove 30 and the guide block. The movable rod 19 synchronously drives the spur gear 21 to rotate, and the spur gear 21 can also slide axially along the gear shaft 22. The gear shaft 22, the rotating shaft 20, the rotating block and the teeth 26 are synchronously driven to rotate through the spur gear 21. The vertical surface of the teeth 26 and the protrusion 25 contacts and moves, thereby making the drum 15 rotate, and then driving the filter cotton belt 14 to rotate, so that different positions of the filter cotton belt 14 can be directed to the air inlet 3, avoiding the filter cotton belt 14 from being directed to the air inlet 3 at the same position for a long time, resulting in excessive dust accumulation and affecting the ventilation effect; when the disk 10 drives the lever 11 to move from the highest position to the lowest position, at this time, the vertical plates 8 on both sides are pushed to move to both sides under the rebound action of the spring 13, thereby making the movable rod 19 move in the opposite direction, the spur gear 21, the gear shaft 22, the rotating shaft 20, the rotating block and the teeth 26 also move in the opposite direction, at this time, the inclined surface at the end of the teeth 26 contacts the protrusion 25, the teeth 26 are squeezed back into the movable groove, and thus the protrusion 25 cannot be pushed to rotate by the teeth 26, and at the same time, the drum 15 and the filter cotton belt 14 will not move, so as to realize the intermittent rotation of the filter cotton belt 14, so that the filtering effect of the filter cotton belt 14 can be exerted to the greatest extent.

[0062] The fixed cylinder 24 is provided with a blowing assembly inside, and the blowing assembly includes a partition 28, and the partition 28 is fixed to the lower part of the inner side of the fixed cylinder 24. The two ends of the partition 28 extend to the two ends of the fixed cylinder 24 respectively and are fixedly connected to the side plate 17.

The side wall of the middle part of the rotating cylinder 15 is set in a grid shape; when working, when the movable rod 19 moves toward the middle of the fixed cylinder 24, it is synchronously pushed The piston 27 moves toward the middle, at which time the air in the upper part of the fixed cylinder 24 can be squeezed into the lower cavity through the through groove 34, and then discharged through the second air outlet 29. The second air outlet 29 is set as a fine slit to increase the exhaust gas flow rate, so that the gas can pass through the rotating cylinder 15 and blow on the inner wall of the filter cotton belt 14, so as to blow off the dust attached to the outer wall of the filter cotton belt 14, so as to restore the dust filtering effect of the filter cotton belt 14; when the movable rod 19 drives the piston 27 to move outward, the air intake speed is increased by setting the air intake hole 33, so that the piston 27 can be quickly reset, and a one-way valve is set in the air intake hole 33 to allow the gas to enter the fixed cylinder 24 in one direction, so as to ensure smooth air intake, and when blowing, the whole body is blown out from the through groove 34.

[0063] A brush 36 is fixed on the inner wall of the lower part of the shell 5, and the end of the brush 36 is in contact with the outer wall of the filter cotton belt 14; during operation, when the filter cotton belt 14 rotates, the dust on the surface of the filter cotton belt 14 is cleaned synchronously by the brush 36, further improving the cleaning efficiency.

[0064] A dust outlet 35 is provided at the bottom of the shell 5, and a collection box 6 is fixed below the dust outlet 35 through a clamping structure; during operation, dust falling from the surface of the filter cotton belt 14 falls into the collection box 6 below through the dust outlet 35 so as to be collected.
