Description

Technical Field

[0001] The present invention relates to the technical field of fan devices, and in particular to a fan device used in a thermal power plant. Background Art

[0002] A thermal power plant, also known as a thermal power plant, is a factory that uses combustible materials (such as coal) as fuel to produce electricity. Its basic production process is: when the fuel burns, it heats water to generate steam, converting the chemical energy of the fuel into thermal energy. The steam pressure drives the turbine to rotate, converting the thermal energy into mechanical energy. The turbine then drives the generator to rotate, converting the mechanical energy into electrical energy.

[0003] It should be noted that when a steam turbine is in use, a fan is required to assist in the intake of air to ensure that the turbine has sufficient air for combustion during operation. However, the main fuel of a thermal power plant is coal, so the air in a thermal power plant is often mixed with a large amount of impurities such as coal ash or dust. When the air is taken in, a filter is added to the fan to filter out the coal ash or dust. However, during long-term use, due to the high content of coal ash or dust, it is very easy to cause the filter to be clogged, which in turn causes the air intake of the fan to decrease rapidly, which not only affects the working efficiency of the steam turbine, but also easily causes the fan motor to burn out due to overload. In addition, when cleaning, the machine needs to be shut down, which will also cause the steam turbine to stop, affecting the production efficiency of the power plant. Even if the filter can filter out most of the coal ash or dust, there is still coal ash or dust that enters the fan and condenses on the fan blades, which in turn increases the mass of the blades, resulting in blade mass imbalance, causing abnormal vibration or even jumping of the fan, and thus preventing the fan from taking in air normally.

[0026] Please refer to the attached manual Figures 1-12 An embodiment of the present invention provides a fan device for a thermal power plant, which includes a fan cover 1 and a fan base 2. The fan base 2 is provided with a buffer base 10, and the fan cover 1 is installed on the buffer base 10. The fan cover 1 is installed with a rotor 3, an air outlet 5 and an air inlet cover 6, and the rotor 3 is installed with multiple blades 4.

[0027] For further information, please refer to the attached manual. Figure 2-Figure 6A fan device for a thermal power plant provided by an embodiment of the present invention also includes an uninterrupted air intake device 7, which is installed in the air outlet 5 and the air inlet cover 6. The uninterrupted air intake device 7 is used to provide uninterrupted air intake for the fan cover 1; specifically, the uninterrupted air intake device 7 includes a mounting frame 701, which is installed on the fan cover 1, and a plurality of filters 702 are installed on the mounting frame 701 in an annular and equidistant manner, and a rotating switching cover 703 is rotatably installed on the mounting frame 701. The rotating switching cover 703 is rotated to clean the plurality of filters 702 and expose the other plurality of filters 702 for uninterrupted air intake. It should be noted that in the embodiment of the present invention, when the fan cover 1 is in operation, if part of the filter 702 is blocked, the wind force of the air outlet 5 is reduced, thereby driving the rotating switching cover 703 to rotate, and the blocked part of the filter 702 can be closed, while the other multiple filter plates 702 are exposed, so as to continuously intake air and realize uninterrupted air intake function.

[0028] More specifically, in an embodiment of the present invention, a switching cleaning device 8 is installed on the uninterrupted air intake device 7, and the switching cleaning device 8 is used to synchronously clean the uninterrupted air intake device 7; the switching cleaning device 8 includes a switching air duct 801, and the switching air duct 801 is connected to the rotating switching cover 703 and the air outlet 5. A plurality of blowing heads 803 are installed on one side of the rotating switching cover 703, and the plurality of blowing heads 803 are used to blow air onto the plurality of filters 702. It should be noted that, in the embodiment of the present invention, when part of the filter 702 is blocked and the rotating switching cover 703 is rotated, the trigger push rod 804 contacts the half-circle trigger strip 802 and is squeezed, and then drives the multiple conducting holes 806 to align with the multiple air blowing heads 803 through the synchronous push plate 805. Moreover, since the wind detection plate 707 closes the air outlet 5, a large amount of wind enters the rotating switching cover 703 through the adapter air duct 801, and is then blown out through the multiple air blowing heads 803, so that the rotating switching cover 703 can blow away the impurities on the multiple filter sheets 702 through the multiple air blowing heads 803 during the rotation process, thereby achieving the purpose of automatic cleaning and further ensuring the continuous air intake of the fan cover 1.

[0029] More specifically, in the embodiment of the present invention, a beating cleaning device 9 is further included. The beating cleaning device 9 is installed on the rotor 3. The beating cleaning device 9 is used to separate the multiple blades 4. The beating cleaning device 9 includes multiple separation racks 901. The multiple separation racks 901 are respectively sleeved on the multiple blades 4, and the multiple separation racks 901 are all installed with blade covers 902. The multiple blade covers 902 are respectively sleeved on the multiple blades 4. It should be noted that in the embodiment of the present invention, when there are many impurities condensed on the blades 4, the fan cover 1 will be greatly beating, and then the integrated push plate 903 will drive the multiple separation racks 901 to move through the rotating retaining ring 905, and then the separation rack 901 will separate the blade cover 902 from the blade 4, so that the blade 4 can be completely cleaned, which can effectively avoid the problem of excessive impurities condensed on the blades 4, causing the blades 4 to be too heavy, and then causing the fan cover 1 to be beating.

[0030] Please continue to refer to the instructions attached Figure 2-Figure 6 Furthermore, in an embodiment of the present invention, a fan device for a thermal power plant is provided, wherein the uninterrupted air intake device 7 further includes a switching column 704, the switching column 704 being rotatably mounted on the mounting frame 701, the rotating switching cover 703 being mounted on the switching column 704, and a rotating lever 705 being mounted on one side of the switching column 704; In addition, a Z-shaped switching frame 706 is movably mounted on the air inlet cover 6, and the Z-shaped switching frame 706 is movably mounted on the rotating lever 705. It should be noted that in the embodiment of the present invention, when some of the filters 702 are clogged, the Z-shaped switching frame 706 drives the switching column 704 to rotate via the rotating lever 705, which in turn drives the rotating switching cover 703 to rotate, thereby sealing the clogged filter 702 and exposing the remaining filters 702, thereby achieving uninterrupted air intake.

[0031] More specifically, in the embodiment of the present invention, a wind force detection plate 707 is rotatably mounted within the air outlet 5. A torsion groove 709 is defined on one inner wall of the air outlet 5. A follower shaft 708 is rotatably mounted within the torsion groove 709, and the wind force detection plate 707 is mounted on the follower shaft 708. Furthermore, a torsion spring 710 is mounted on the torsion groove 709, and the torsion spring 710 is mounted on the follower shaft 708. It should be noted that in the embodiment of the present invention, when multiple filters 702 are clogged, the wind force at the air outlet 5 is reduced. At this time, the rebound force of the torsion spring 710 causes the follower shaft 708 to rotate the wind force detection plate 707, thereby rotating the rotating switch cover 703, thereby achieving the purpose of automatically switching the filters 702.

[0032] More specifically, in the embodiment of the present invention, a follower rotating plate 711 is mounted on one end of the follower rotating shaft 708, and the Z-type switching frame 706 is movably mounted on the follower rotating plate 711. In addition, the Z-type switching frame 706 is provided with two switching sliding holes 712, and a switching sliding shaft 713 is movably mounted in each of the switching sliding holes 712. The two switching sliding shafts 713 are respectively mounted on the rotating lever 705 and the follower rotating plate 711. It should be noted that in the embodiment of the present invention, when the follower rotating shaft 708 rotates, it drives one switching sliding shaft 713 to rotate via the follower rotating plate 711. The rotation of the switching sliding shaft 713 drives the Z-type switching frame 706 to move. The Z-type switching frame 706 drives the rotating lever 705 to rotate via the other switching sliding shaft 713. The two switching sliding shafts 713 slide in the two switching sliding holes 712, respectively, thereby achieving rotational switching of the rotating switching cover 703.

[0033] Please refer to the attached manual Figure 2-Figure 3 and Figure 7 Furthermore, in an embodiment of the present invention, a fan device for a thermal power plant is provided, wherein the switching and cleaning device 8 further includes a synchronous push plate 805, which is located within the rotating switching cover 703. The synchronous push plate 805 is provided with a plurality of conductive holes 806, which are arranged correspondingly with the plurality of air blowing heads 803. It should be noted that in this embodiment of the present invention, the synchronous push plate 805 is aligned with the plurality of air blowing heads 803 via the plurality of conductive holes 806, thereby achieving the function of conducting airflow.

[0034] More specifically, in the embodiment of the present invention, a rebound spring 807 is installed on one side of the synchronous push plate 805, and the rebound spring 807 is installed on the inner wall of the rotating switching cover 703. In addition, a trigger push rod 804 is movably installed on the rotating switching cover 703, and the trigger push rod 804 is installed on the synchronous push plate 805. A half-circle trigger bar 802 is installed in the air inlet cover 6, and the half-circle trigger bar 802 is used to squeeze the trigger push rod 804. It should be noted that in the embodiment of the present invention, when the rotating switching cover 703 rotates, the trigger push rod 804 contacts and is squeezed by the half-circle trigger bar 802, which then causes the trigger push rod 804 to drive the synchronous push plate 805 to move and apply force to the rebound spring 807. At the same time, the synchronous push plate 805 causes the multiple conductive holes 806 to align with the multiple blowing heads 803, thereby achieving the purpose of automatic blowing.

[0035] Please refer to the instruction manual Figures 8-12 Furthermore, in a fan device for a thermal power plant provided by an embodiment of the present invention, the vibration cleaning device 9 further includes an integrated push plate 903, and limiting guide rods 906 are movably installed at the four corners of the integrated push plate 903, and the four limiting guide rods 906 are all installed on the inner wall of the fan cover 1; In addition, a plurality of separation racks 901 are mounted with rotating retaining rings 905, and a rotating groove 904 is defined on the integrated push plate 903. The rotating retaining rings 905 are rotatably mounted within the rotating groove 904. It should be noted that in the embodiment of the present invention, when the rotor 3 rotates, the rotor 3 drives the plurality of separation racks 901 to rotate, and the plurality of separation racks 901 rotate within the rotating groove 904 via the rotating retaining rings 905. Simultaneously, when the integrated push plate 903 moves, it moves horizontally on the four limiting guide rods 906, thereby moving the separation racks 901.

[0036] To be more specific, in an embodiment of the present invention, locking holes 907 are provided at the four corners of the integrated push plate 903, and four locking seats 908 are installed on the inner wall of the fan cover 1, and the four locking seats 908 are used to lock the integrated push plate 903; locking baffles 909 are rotatably installed on both sides of the locking seat 908, and an installation cavity 910 is provided on the locking baffle 909, and a connecting shaft 911 is rotatably installed in the installation cavity 910, and the connecting shaft 911 is installed on the locking seat 908, and a locking torsion spring 912 is installed on the connecting shaft 911, and the locking torsion spring 912 is installed on the inner wall of the installation cavity 910. It should be noted that, in the embodiment of the present invention, when the integrated push plate 903 moves, the four locking seats 908 pass through the four locking holes 907 respectively, and in the process of the integrated push plate 903 moving, the multiple locking baffles 909 are squeezed back at the same time, so that the locking baffle 909 rotates on the connecting shaft 911 through the installation cavity 910, and drives the locking torsion spring 912 to be subjected to force. Therefore, after the integrated push plate 903 moves into place, under the rebound force of the locking torsion spring 912, the locking baffle 909 is driven to rebound and get stuck on the integrated push plate 903, thereby fixing the integrated push plate 903 on the fan cover 1.

[0037] Please continue to refer to the instructions attached Figures 8-12 More specifically, in the embodiment of the present invention, a mounting seat 914 is mounted on the inner wall of the fan cover 1, a separation rotating rod 915 is rotatably mounted on the mounting seat 914, and the separation rotating rod 915 is movably mounted on one side of the integrated push plate 903; two separation sliding shafts 917 are rotatably mounted on the separation rotating rod 915, one separation sliding shaft 917 is mounted on the mounting seat 914, a separation sliding groove 916 is opened on one side of the integrated push plate 903, and the other separation sliding shaft 917 is slidably mounted in the separation sliding groove 916; In addition, a jumping push frame 913 is slidably mounted on the fan cover 1, and a separation driving shaft 918 is mounted on the jumping push frame 913. The jumping push frame 913 moves upward and drives the separation rotating rod 915 to rotate through the separation driving shaft 918. It should be noted that in the embodiment of the present invention, when the fan cover 1 has a large jump, the fan cover 1 drives the jumping push frame 913 to be squeezed and moved upward by the fan base 2, and the jumping push frame 913 moves and drives the separation rotating rod 915 to rotate through the separation driving shaft 918. The separation rotating rod 915 rotates on a separation sliding shaft 917, and at the same time, the separation rotating rod 915 drives the integrated push plate 903 to move through another separation sliding shaft 917. At the same time, the separation sliding shaft 917 slides in the separation sliding groove 916. The integrated push plate 903 moves through the rotating retaining ring 905 to drive multiple separation frames 901 to move, thereby causing the separation frame 901 to separate the blade sheath 902 from the blade 4, thereby completely cleaning the blade 4.

[0038] More specifically, in the embodiment of the present invention, each of the four corners of the top side of the fan base 2 is movably mounted with a bouncing buffer rod 919, which is mounted on the buffer base 10. Furthermore, each of the four corners of the top side of the fan base 2 is mounted with a bouncing buffer spring 920, which is mounted on the buffer base 10. It should be noted that in the embodiment of the present invention, when the fan cover 1 bobs, the multiple bouncing buffer rods 919 move on the buffer base 10, driving the multiple bouncing buffer springs 920 to bear force. Therefore, under the rebound force of the multiple bouncing buffer springs 920, the buffer base 10 is buffered, ensuring the safe operation of the fan cover 1.

[0039] In summary, the working principle of a fan device for a thermal power plant provided by an embodiment of the present invention is as follows: When the fan cover 1 is in operation, air enters the fan cover 1 through multiple filters 702, and is then discharged through the air outlet 5, blowing the wind detection plate 707 to rotate and open. The rotation of the wind detection plate 707 drives the follower shaft 708 to rotate, and the follower shaft 708 rotates in the torsion groove 709, driving the torsion spring 710 to be stressed. It should be noted that when multiple filters 702 are blocked, the wind force of the air outlet 5 is reduced. At this time, under the rebound force of the torsion spring 710, the follower shaft 708 drives the wind force detection plate 707 to rotate. At the same time, the follower shaft 708 drives a switching slide shaft 713 to rotate through the follower rotating plate 711. The rotation of the switching slide shaft 713 drives the Z-shaped switching frame 706 to move. The Z-shaped switching frame 706 drives the rotating lever 705 to rotate through another switching slide shaft 713, and the two switching slide shafts 713 slide in the two switching slide holes 712 respectively. When the rotating lever 705 rotates, it drives the rotating switching cover 703 to rotate through the switching column 704, thereby closing the blocked part of the filter 702 and exposing the other multiple filters 702 for air intake, thereby achieving uninterrupted air intake function. Furthermore, when part of the filter 702 is clogged, causing the wind force detection plate 707 to rotate, and then when the rotating switching cover 703 rotates, the trigger push rod 804 contacts the half-circle trigger bar 802 and is squeezed, and then the trigger push rod 804 drives the synchronous push plate 805 to move and causes the rebound spring 807 to be stressed, and at the same time, the synchronous push plate 805 drives the multiple through holes 806 to align with the multiple air blowing heads 803, and because the wind force detection plate 707 closes the air outlet 5, at this time a large amount of wind enters the rotating switching cover 703 through the adapter air duct 801, and is then blown out through the multiple air blowing heads 803, so that the rotating switching cover 703 blows away the impurities on the multiple filter sheets 702 through the multiple air blowing heads 803 during the rotation process, thereby achieving the purpose of automatic cleaning, and thus ensuring the air intake efficiency of the fan cover 1; In addition, it should be noted that when there are a lot of impurities condensed on the blades 4, causing the fan cover 1 to jump significantly, the fan cover 1 drives the jumping push frame 913 to be squeezed upward by the fan base 2, and the jumping push frame 913 moves through the separation push shaft 918 to push the separation rotating rod 915 to rotate, and the separation rotating rod 915 rotates on a separation sliding shaft 917, and the separation rotating rod 915 drives the integrated push plate 903 to move through another separation sliding shaft 917. At the same time, the separation sliding shaft 917 slides in the separation slide groove 916, and the integrated push plate 903 moves through the rotating retaining ring 905 to drive multiple separation frames 901 to move, thereby causing the separation frame 901 to separate the blade sheath 902 from the blade 4, thereby completely cleaning the blade 4, thereby effectively avoiding excessive impurities condensed on the blade 4, causing the blade 4 to be too heavy, and then causing the fan cover 1 to jump.
