[0002] The air-cooling island is a large-scale industrial heat exchange equipment that uses natural air to cool process fluids. It is mainly used in large thermal power plants.

[0003] Most of the existing mechanical ventilation direct air cooling systems have the problem that the air cooling island flow field is affected by the environmental lateral wind, resulting in deterioration of the performance of the air cooling unit axial flow fan, a significant decrease in cooling air flow, and even hot air backflow under strong wind conditions; as the wind speed increases, the adverse effects of the environmental lateral wind spread to the downstream axial flow fan and gradually decay, and the performance of the leeward side axial flow fan is improved.

[0010] Preferably, a connecting rod is inserted and fixed on the middle side of the top of the upper shell of the sensor housing; an optical detection component is fixedly arranged on the top of the connecting rod, and the optical detection component is fixedly arranged inside the detection cylinder.

[0011] Preferably, three groups of detection tubes and detection components and a windshield are arranged on the outer side of the fixing frame at an angle of 90 degrees.

[0012] Preferably, the optical detection assembly is specifically composed of a detection grating and a photosensitive rod, and the bottom of the photosensitive rod is fixedly connected to the top of the connecting rod.

[0013] Preferably, three groups of adjustment plates and elastic cloth are evenly distributed inside the guide inner shell; and 12 groups of guide adjustment parts, guide tubes and jet spheres are evenly distributed at an angle of 30 on the adjustment plates.

[0014] A method for using a flow field balance control device for improving the heat dissipation capacity of an air cooling island of a coal-fired power unit comprises the following steps:

[0015] Step 1: Data collection: During the operation of the air cooling equipment, the multi-axis connecting arm is controlled by the remote control terminal to drive the fixed frame to adjust the distance between it and the air cooling platform. The windshield is affected by the airflow and drives the sensor housing and the connecting rod in the flow velocity detection component to rotate, so that the connecting rod drives the light sensing rod in the optical detection component to rotate, so that the detection grating and the light sensing rod in the optical detection component perform sensing actions. Here, due to the prismatic setting of the surface of the windshield, there is a certain degree of guidance for the wind speed and direction, and the rounded corners can make the wind pass through the windshield at a faster speed, effectively reducing the windshield. The turbulence around the plate has little effect on the original wind field, and can also effectively reduce the impact on the detection of the flow velocity detection component. Here, the ambient wind speed is determined by the detection data of the flow velocity detection component, and the wind direction can also be determined by the inclination angle of multiple groups of wind shields; then the heating coil is provided with electrical energy to increase its overall temperature. After the ambient airflow passes through, it will drive the heat on the heating coil to flow to one side, and then the flow direction of the heat airflow is detected by the temperature measuring resistor, and the wind direction is further determined by combining the inclination angle data of the wind shield, so as to improve the detection quality of the ambient wind direction and wind speed;

[0016] Step 2, multi-stage diversion; during the operation of the air cooling equipment, the ambient air flows through the outside of the diversion shell, where the second electromagnetic coil block in the diversion adjustment member is intermittently energized through the control terminal. After the second electromagnetic coil block is energized and magnetized, it pushes the permanent magnet to slide inside the magnetic isolation shell and squeezes the airbag. Here, the airbag is squeezed and quickly expands toward the flow outlet of the magnetic isolation shell. The airbag squeezes the airflow into the inside of the diversion tube inside the magnetic isolation shell, and guides it to the inside of the diversion inner shell through the jet sphere;

[0017] Step three, wind direction angle adjustment; by detecting the detection data of the detection component, the first electromagnetic coil block at the same height is powered in series, so that the adjustment plate is adjusted up and down at the internal groove of the guide inner shell. During the displacement process, the adjustment plate pulls the guide tube up and down to form an arc flow channel. The airflow introduced by the guide adjustment component will also form a certain wind inlet direction below the air cooling equipment along the guide tube.

[0018] The present invention has the following advantages: The present invention provides a flow field balance control device for improving the heat dissipation capacity of the air cooling island of a coal-fired power unit through improvement. Compared with the same type of equipment, the present invention has the following improvements:

[0019] The present invention discloses a flow field balancing control device for improving the heat dissipation capacity of an air-cooling island of a coal-fired power unit.

The detection component is arranged on the side of the air-cooling platform, and the dual detection of heat and grating of the wind shield and flow velocity detection component is used to improve the high-quality detection of wind speed and wind direction. The device has the advantages of miniaturization, integration, low cost, and the ability to simultaneously measure wind speed and direction. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Embodiment 2:

[0036] See also Figure 1 to Figure 6 , a flow field balance control device for improving the heat dissipation capacity of an air-cooling island of a coal-fired power unit of the present invention, compared with the first embodiment, this embodiment also includes: a detection component 4 with a detection function is fixedly installed at the bottom of the air-cooling platform 1 by bolts; the detection component 4 includes a multi-axis connecting arm 41 fixedly installed at the bottom of the top of the air-cooling platform 1 by bolts; a fixing frame 42 is fixedly installed at the end of the multi-axis connecting arm 41 by bolts; a detection cylinder 43 is plugged and fixed on the outside of the fixing frame 42; a wind shield sleeve 44 is fixedly provided at the end of the bottom side of the detection cylinder 43; a flow velocity detection component 45 is fixedly provided on the bottom side of the wind shield sleeve 44; a wind shield plate 46 is fixedly provided at the bottom of the detection component 45, and the surface of the wind shield plate 46 is a prismatic guide groove; three groups of detection cylinders 43, detection components 45 and wind shield plates 46 are distributed up and down at a 90-degree angle on the outside of the fixing frame 42.

[0037] The flow rate detection component 45 includes a sensor shell 451 rotatably set at the bottom of the wind shield sleeve 44, and the bottom of the lower shell of the sensor shell 451 is fixedly connected to the wind shield plate 46; a heating coil 452 is fixedly set on the middle side of the upper and lower shells of the sensor shell 451; a temperature measuring resistor 453 with a detection function is fixedly set on the upper and lower sides of the shell of the sensor shell 451; a connecting rod 454 is plugged and fixed on the middle side of the top of the upper shell of the sensor shell 451; an optical detection component 455 is fixedly set on the top of the connecting rod 454, and the optical detection component 455 is fixedly set inside the detection tube 43; the optical detection component 455 is specifically composed of a detection grating and a photosensitive rod, and the bottom of the photosensitive rod is fixedly connected to the top of the connecting rod 454.

[0038] The working principle of the flow field balance control device for improving the heat dissipation capacity of the air cooling island of a coal-fired power unit is as follows:

[0039] First, when using this device, first place the device in the working area, and then connect the device to an external power source to provide the device with the power required for operation;

[0040] Second, during the operation of the air cooling device 2, the staff here controls the multi-axis connecting arm 41 through the remote control terminal to drive the fixing frame 42 to adjust the distance between it and the air cooling platform 1. Here, the windshield 46 is affected by the airflow and drives the sensor housing 451 and the connecting rod 454 in the flow velocity detection component 45 to rotate, so that the connecting rod 454 drives the light sensing rod in the light detection component 455 to rotate, so that the detection grating and the light sensing rod in the light detection component 455 perform sensing actions. Here, due to the prismatic setting of the surface of the windshield 46, there is a certain degree of guidance for the wind speed and direction, and the rounded corners are processed, so that the wind can pass through the windshield 46 at a faster speed, effectively reducing the turbulence around the windshield 46, having little impact on the original wind field, and can also effectively reduce the detection impact on the flow velocity detection component 45. Here, the environmental wind speed is determined by the detection data of the flow velocity detection component 45, and the wind direction can also be determined by the inclination angle of multiple groups of windshields 46.

[0041] Third, the staff then provides electrical energy to the heating coil 452 to raise its overall temperature. The ambient airflow here will drive the heat on the heating coil 452 to flow to one side, and then the temperature measuring resistor 453 is used to detect the flow direction of the heat airflow, and the inclination angle data of the wind shield 46 is combined to further determine the wind direction, so as to improve the detection quality of the ambient wind direction and wind speed;

[0042] Fourth, during the operation of the air cooling device 2, the ambient air flows through the outside of the guide shell 31, and the second electromagnetic coil block 332 in the guide adjustment member 33 is intermittently energized by the control terminal. After the second electromagnetic coil block 332 is energized and magnetized, it pushes the permanent magnet 333 to slide inside the magnetic isolation shell 331 and squeezes the airbag 334. Here, the airbag 334 is squeezed and quickly expands toward the flow outlet direction of the magnetic isolation shell 331. The airbag 334 squeezes the airflow into the guide tube 34 inside the magnetic isolation shell 331, and guides it to the inside of the guide inner shell 32 through the jet sphere 35;

[0043] Fifth, the staff here determines the wind direction angle between the ambient wind and the air-cooling platform 1 through the detection data of the detection component 4, and then uses the control terminal to power the first electromagnetic coil block 38 at the same height in series, so that the adjustment plate 36 is adjusted up and down at the internal groove of the guide inner shell 32. During the displacement process, the adjustment plate 36 pulls the guide tube 34 up and down to form an arc flow channel. The airflow introduced by the guide adjustment member 33 will also form a certain wind inlet direction under the air-cooling device 2 along the guide tube 34. By changing the wind direction angle between the ambient wind and the air-cooling device 2 and combining the ambient wind speed to improve the flow field around the air-cooling device 2, the efficiency of the ambient wind entering the air-cooling device 2 is improved while reducing the backflow of hot air.

[0044] The present invention provides a flow field balancing control device for improving the heat dissipation capacity of an air-cooling island of a coal-fired power unit through improvement. By arranging a guide component 3 below an air-cooling device 2, the guide component 3 changes the wind direction angle between the ambient wind and the air-cooling device 2, and improves the flow field around the air-cooling device 2 in combination with the ambient wind speed, thereby improving the efficiency of the ambient wind entering the air-cooling device 2 and reducing the backflow of hot air. By arranging a detection component 4 on the side of an air-cooling platform 1, the dual detection of heat and grating of a windshield 46 and a flow velocity detection component 45 is used to improve the high-quality detection of wind speed and wind direction, and the device has the advantages of miniaturization, integration, low cost, and the ability to simultaneously measure wind speed and wind direction.
