Description

Technical Field

[0001] The present invention belongs to the technical field of gas turbines, and particularly relates to a gas turbine blade and a gas turbine equipped with the gas turbine blade. Background Art

[0002] A gas turbine is a thermal engine that uses continuously flowing gas as the working medium and converts fuel energy into mechanical energy through a rotating impeller. Its core definition can be summarized as: compressing air through a compressor → mixing and burning fuel in a combustion chamber to generate high-temperature and high-pressure gas → expanding and doing work in a turbine. Due to its high efficiency, flexibility, high power density and other characteristics, the gas turbine has formed four core application systems: power generation, transportation, industrial power, and emerging scenarios. In the power generation field, due to its excellent peak shaving ability, its total power generation has accounted for one-fifth of the total global power generation.

[0003] Existing gas turbines can be used as backup power sources in scenarios such as hospitals and data centers. However, there are the following problems during use. First, when starting, the rotational speed of the main shaft of the gas turbine is slow due to the need to compress air. To accelerate the startup speed of the equipment, a starting motor is required to assist the main shaft in rotating. Generally, in the method of assisting startup by a motor, after startup, the output shaft of the motor will rotate synchronously with the main shaft. When the equipment is running at high speed, the starting motor is no longer needed to assist in rotation, but at this time, the main shaft is still connected to the output shaft of the starting motor, which will cause a large burden on the starting motor. Second, the gas turbine needs to reach a certain temperature to operate stably during use. In the initial startup of existing gas turbines, since the compressed air is generally cold air, and the combustion in the combustion chamber is insufficient at low rotational speeds, it is difficult to quickly increase the temperature. In addition, the blades of existing gas turbines require good heat dissipation ability, and the efficiency of introducing gas by the shape of conventional micropores is low, resulting in poor heat dissipation ability of the blades.

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention; the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, unless otherwise clearly specified and defined, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In this technical solution, as Figure 1-10 shown, a gas turbine with gas turbine blades includes a mounting base plate 1, on which gas turbine mounting brackets 2 are fixedly installed in an array. A gas turbine body 3 is fixedly installed on the gas turbine mounting brackets 2. The gas turbine with gas turbine blades further includes:

[0039] A starting mechanism 4, which includes an auxiliary rotating motor 401 and an insertion cylinder 421. The auxiliary rotating motor 401 is installed on the left side of the gas turbine body 3, and the insertion cylinder 421 is installed on the output shaft of the auxiliary rotating motor 401.

[0040] A hot gas collection mechanism 5, which includes a bell mouth 501, an exhaust cylinder 502, and a second connecting pipe 504. The bell mouth 501 faces the right side of the gas turbine body 3. The exhaust cylinder 502 is fixedly installed at the right end of the bell mouth 501, and the second connecting pipe 504 is installed on the exhaust cylinder 502.

[0041] An installation mechanism 6, which includes a first installation bracket 601 and a second installation bracket 605. The auxiliary rotating motor 401 is installed on the first installation bracket 601, and the exhaust cylinder 502 is installed on the second installation bracket 605.

[0042] A power supply mechanism 7, which includes a storage battery 701 and a control panel 702. The storage battery 701 is fixedly installed on the left side of the mounting base plate 1, and the control panel 702 is fixedly installed on the storage battery 701, so as to Figure 1This is the front view. The left end of the gas turbine body 3 is the compressor end, and the right end is the turbine exhaust end. The starting mechanism 4 is movably connected to the hexagonal block 422 provided on the main shaft of the gas turbine body 3. When the main shaft of the gas turbine body 3 rotates at high speed, the insertion cylinder 421 will be disengaged from the hexagonal block 422, so that when the main shaft of the gas turbine body 3 rotates at high speed, the output shaft of the auxiliary rotating motor 401 is automatically disengaged from the main shaft of the gas turbine body 3, thereby protecting the output shaft of the auxiliary rotating motor 401 and preventing its output shaft from being driven to rotate for a long time and causing adverse effects on the auxiliary rotating motor 401. The bell mouth 501 provided on the hot gas collecting mechanism 5 can collect hot gas with high efficiency. Since the fuel in the combustion chamber burns insufficiently when the gas turbine body 3 starts, the discharged hot gas will contain more impurities. By removing the impurities through the cyclone separator 509 and the impurity adsorption layer 510 with good adsorption effect on impurities, carbon deposition during the hot gas circulation can be effectively avoided. Moreover, the starting mechanism 4 and the hot gas collecting mechanism 5 provided on the equipment are relatively separated from the gas turbine body 3, so there is no strict requirement for the model of the gas turbine body 3. At the same time, this structure also makes the maintenance and other work of the equipment very convenient.

[0043] Furthermore, the starting mechanism 4 further includes an auxiliary rotating motor 401, a first connecting wheel 402, a second connecting wheel 403, a limiting frame 404, a guide rod 405, a return spring 406, a counterweight 407, a hinged rod 408 and a pressure sensor 409. The output shaft of the auxiliary rotating motor 401 is fixedly installed with a first connecting wheel 402. A second connecting wheel 403 is provided on one side of the first connecting wheel 402. Two groups of limiting frames 404 are fixedly installed on the first connecting wheel 402. A guide rod 405 is fixedly installed in the limiting frame 404. A return spring 406 is sleeved on the guide rod 405. A counterweight 407 is movably sleeved on the guide rod 405. One end of the return spring 406 abuts against the counterweight 407. A hinged rod 408 is hinged on the counterweight 407. One end of the hinged rod 408 is hinged on the second connecting wheel 403. An insertion cylinder 421 is fixedly installed on the second connecting wheel 403. A pressure sensor 409 is fixedly installed on the opposite sides of the first connecting wheel 402 and the second connecting wheel 403. The schematic diagram of this structure is Figure 2 and Figure 3, when the auxiliary rotating motor 401 starts, it drives the first connecting wheel 402 to rotate. The rotation of the first connecting wheel 402 drives the second connecting wheel 403 to rotate through the hinge rod 408. When the first connecting wheel 402 rotates, the counterweight 407 moves outward along the guide rod 405 under the action of centrifugal force and compresses the return spring 406, so that the hinge rod 408 gradually becomes horizontal and pulls the second connecting wheel 403 closer to the first connecting wheel 402. After the first connecting wheel 402 reaches a certain rotational speed, the insertion cylinder 421 and the hexagonal block 422 are separated under the pull of the hinge rod 408. When they are completely separated, the pressure sensor 409 will fit. After the pressure sensor 409 senses the pressure, it will remotely control the auxiliary rotating motor 401 to stop working, so as to realize the separation of the output shaft of the auxiliary rotating motor 401 from the main shaft of the gas turbine wheel body 3 at high rotational speed, and achieve the protection of the output shaft of the auxiliary rotating motor 401.

[0044] Further, the starting mechanism 4 further includes a first placement groove 410, a semi-circular frame 411, a triangular block 412, a rotating groove 413, a rotating rod 414, a torsion spring 415, an arc block 416, an arc groove 417, a limiting rod 418, an anti-slip strip 419, a finger groove 420, an insertion cylinder 421 and a hexagonal block 422. A first placement groove 410 is opened on the limiting frame 404. A semi-circular frame 411 is fixedly installed on the upper side of the first placement groove 410. A triangular block 412 is rotatably installed in the semi-circular frame 411. A rotating groove 413 is opened at one end of the triangular block 412. A rotating rod 414 is rotatably installed in the rotating groove 413. A torsion spring 415 is sleeved on the rotating rod 414. One end of the torsion spring 415 is fixedly installed on the inner wall of the rotating groove 413. The rotating rod 414 is fixedly installed in the semi-circular frame 411. An arc block 416 is fixedly installed on the upper side of the triangular block 412. An arc groove 417 is opened on the arc block 416. A limiting rod 418 is inserted in the arc groove 417. The limiting rod 418 is fixedly installed in the semi-circular frame 411. Anti-slip strips 419 are fixedly installed in an array on the arc block 416. A finger groove 420 is opened on the upper side of the semi-circular frame 411. A hexagonal block 422 is fixedly installed on the main shaft of the gas turbine wheel body 3. The hexagonal block 422 is inserted into the insertion cylinder 421. The schematic diagram of this structure is Figure 4 , to Figure 4For example, the lower side of the triangular block 412 is an inclined surface while the left side is a right-angle surface. In the normal state of the torsion spring 415, the inclined surface of the triangular block 412 faces the counterweight block 407, and the lower end of the triangular block 412 does not contact the return spring 406 to avoid the generation of movement interference. The arc groove 417 and the limit rod 418 can limit the rotation range of the triangular block 412, so that when the counterweight block 407 fits against the right-angle surface of the triangular block 412, the triangular block 412 can limit the counterweight block 407 and will not cause the rotation of the triangular block 412 during the fitting. The provided anti-slip strip 419 and finger grooves 420 enable the triangular block 412 to be manually toggled, facilitating the reset of the counterweight block 407 by the staff after the equipment operation ends, thereby restoring its normal function.

[0045] Furthermore, the hot gas collection mechanism 5 further includes a bell mouth 501, an exhaust pipe 502, a first connecting pipe 503, a second connecting pipe 504, a spherical groove 505, an adjusting ball 506, a ventilation port 507, and an adjusting motor 508. The first connecting pipe 503 is fixedly installed on the upper side of the exhaust pipe 502, and the second connecting pipe 504 is installed on the first connecting pipe 503. One end of the second connecting pipe 504 is communicated with the air inlet of the gas turbine wheel body 3. A spherical groove 505 is provided at the central position of the exhaust pipe 502, and an adjusting ball 506 is rotatably installed in the spherical groove 505. Ventilation ports 507 are provided at the upper and lower ends and the left side of the adjusting ball 506. The adjusting motor 508 is fixedly installed on the front side of the exhaust pipe 502, and the output shaft of the adjusting motor 508 is fixedly installed on the adjusting ball 506. The schematic diagram of this structure is Figure 5 and Figure 6 , the cross-sectional diameter of the spherical groove 505 is larger than the inner diameter of the exhaust pipe 502, the diameter of the ventilation port 507 is equal to the inner diameter of the exhaust pipe 502, and the ventilation ports 507 provided on the adjusting ball 506 are in a T shape. Under the action of the rotation of the output shaft of the adjusting motor 508, the adjusting ball 506 can rotate, so as to quickly preheat the hot gas generated by the gas turbine wheel body 3 into the air inlet of the gas turbine wheel body 3 by rotating the adjusting ball 506, or to block the connection with the first connecting pipe 503 and select to connect with the exhaust pipe 502, so that the exhaust pipe 502 can discharge the hot gas. At this time, the hot gas is no longer supplied to the gas turbine wheel body 3 to avoid overheating inside the gas turbine wheel body 3.

[0046] Furthermore, the hot gas collection mechanism 5 further includes a cyclone separator 509, an impurity adsorption layer 510, a first flange 511, and a second flange 512. The cyclone separator 509 is fixedly installed on the first connecting pipe 503. One end of the air outlet of the cyclone separator 509 is fixedly connected to one end of the second connecting pipe 504. The impurity adsorption layer 510 is fixedly installed inside the cyclone separator 509. The first flange 511 is fixedly installed at both ends of the second connecting pipe 504, and the second flange 512 is fixedly installed at one end of the exhaust pipe 502. The schematic diagram of this structure is Figure 5 , which enables the hot gas for rapid preheating to be adsorbed and filtered by the impurity adsorption layer 510. The cyclone separator 509 is brought in and used as an existing technology, and its filtering principle is as follows: The dust-containing gas enters the cylindrical part of the cyclone separator 509 at a high speed in a tangential direction, forming a spiral rotating air flow. The particles are thrown towards the inner wall of the separator, that is, the impurity adsorption layer 510, due to the centrifugal force. The rotating air flow gradually contracts towards the center during the downward process, forming an upward inner swirling flow. The purified gas is discharged through the exhaust pipe at the top. The filtering method of the cyclone separator 509 will not overly affect the flow rate of the hot gas, and enables the second connecting pipe 504 to be disassembled. At the same time, the exhaust pipe 502 can also be connected to other waste heat utilization devices, increasing the functionality of the equipment during use.

[0047] Furthermore, the installation mechanism 6 further includes a first installation bracket 601, a first installation plate 602, a first screw rod 603, a first screw sleeve 604, a second installation bracket 605, a second screw sleeve 606, a second installation plate 607, and a second screw rod 608. The first installation bracket 601 is fixedly installed on the left side of the installation base plate 1. Two groups of first installation plates 602 are fixedly installed on the auxiliary rotation motor 401. Two groups of first screw rods 603 are movably inserted into one group of first installation plates 602. Four groups of first screw sleeves 604 are fixedly installed on the upper side of the first installation bracket 601. The first screw rod 603 is installed in the first screw sleeve 604 through threads. The shape of the second installation bracket 605 is adapted to the shape of the lower side of the exhaust pipe 502. Second screw sleeves 606 are fixedly installed at the ends of the second installation bracket 605. Four groups of second installation plates 607 are fixedly installed on the exhaust pipe 502. Second screw rods 608 are movably inserted into the second installation plates 607. The second screw rod 608 is installed in the second screw sleeve 606 through threads. The schematic diagram of this structure is Figure 2 , Figure 5 and Figure 6 , which enables the starting mechanism 04 and the hot gas collection mechanism 5 to be completely disassembled, so that the starting mechanism 04 and the hot gas collection mechanism 5 can be conveniently overhauled, increasing the convenience during equipment overhaul.

[0048] Furthermore, the mounting mechanism 6 also includes a third mounting bracket 609, a second placement groove 610, an insertion hole 611, a third screw 612, a third screw sleeve 613 and a wire hook 614.

The schematic diagram of the structure is as follows: Figure 8 and Figure 9 This structure enables the third mounting bracket 609 to receive the second connecting pipe 504, thereby reducing the pressure of the second connecting pipe 504 on the gas turbine body 3 and increasing the stability of the device when in use. The wire clamping hook 614 can effectively gather the wires 705 and the oil pipe 708, increasing the convenience of the device when in use.

[0049] Furthermore, the power supply mechanism 7 also includes a battery 701, a control panel 702, an output port 703, an input port 704, and a wire 705. The control panel 702 is equipped with three groups of output ports 703 and one group of input ports 704. The output ports 703 and the input ports 704 are both connected to the wire 705. The wire 705 is connected to the auxiliary rotating motor 401 and the regulating motor 508. The schematic diagram of the structure is as follows: Figure 7 and Figure 8 This structure allows the battery 701 to start through the control panel 702 when the power is off, so that the starting mechanism 04 and the hot air collection mechanism 5 can be started in time, thereby achieving rapid startup of the equipment.

[0050] Furthermore, the power supply mechanism 7 further includes an oil tank 706, a transmission oil pump 707, and an oil pipe 708. The oil tank 706 is fixedly mounted on the mounting base plate 1, the transmission oil pump 707 is fixedly mounted on the oil tank 706, the oil delivery port of the transmission oil pump 707 is fixedly mounted with an oil pipe 708, the oil pipe 708 is connected to the fuel pump on the gas turbine body 3, and the transmission oil pump 707 is connected to the battery 701 through the wire 705. The schematic diagram of the structure is as follows: Figure 8 This structure allows the fuel to enter the gas turbine body 3 in time, so that the gas turbine body 3 can be started quickly, thereby improving the response speed of the equipment during operation.

[0051] Furthermore, the present invention also provides a gas turbine blade, which is applied to a gas turbine equipped with the above gas turbine blade. The gas turbine blade is adapted to a blade mounting wheel within the gas turbine body 3. Among them, the gas turbine blade includes mounting blocks 8 that are arranged on the blade mounting wheel in an array and turbine blades 9 that are fixedly installed on each mounting block 8. Tear-shaped holes 10 are arrayed and opened on the front side of the turbine blades 9. The schematic diagram of this structure is Figure 10 , through the shape of the tear-shaped holes 10, the tear-shaped hole 10 structure can effectively suppress the jet effect at the hole inlet and reduce the range of the low-momentum region near the downstream wall surface of the hole outlet. This makes the transverse velocity distribution at the outlet of the film hole more uniform, provides more stable and larger-coverage film cooling for the blade surface, and thus can improve the heat dissipation efficiency of the turbine blade 9.

[0052] Working principle: When the present invention is working, in case of a power failure, the external power source connected to the input port 704 no longer supplies power to the storage battery 701. At this time, the control panel 702 controls the storage battery 701 to start, so that the auxiliary rotation motor 401 starts. The output shaft of the auxiliary rotation motor 401 rotates to drive the first connection wheel 402 to rotate, and drives the second connection wheel 403 to rotate through the articulated rod 408, thereby driving the insertion cylinder 421 to rotate, and further driving the hexagonal block 422 and the main shaft of the gas turbine body 3 connected thereto to rotate, so as to realize the rapid start of the gas turbine body 3.

[0053] At the same time, the transfer oil pump 707 starts to extract the fuel in the fuel tank 706 and enters the combustion chamber of the gas turbine body 3 through the oil pipe 708. The hot gas generated by the operation of the gas turbine body 3 will be guided by the bell mouth 501 and enter the first connection pipe 503 through the ventilation port 507, and enter the cyclone separator 509 to be filtered by the impurity adsorption layer 510, and then enter the exhaust port of the gas turbine body 3 through the second connection pipe 504, so as to realize the preheating of the air in the gas turbine body 3.

[0054] After the gas turbine body 3 is fully started, the main shaft speed of the gas turbine body 3 increases. Under the action of centrifugal force, the counterweight 407 moves outward and presses the triangular block 412 to rotate the triangular block 412 until the counterweight 407 abuts against the right-angled side of the triangular block 412. At this time, the articulated rod 408 is pulled to the horizontal, so that the insertion cylinder 421 and the hexagonal block 422 are relatively separated, and the pressure sensors 409 are in contact with each other, and the control auxiliary rotation motor 401 stops running. At this time, the adjustment motor 508 is started, so that the output shaft of the adjustment motor 508 rotates counterclockwise by 90 degrees, so that the first connecting pipe 503 is shielded, and the exhaust cylinder 502 can normally discharge hot air. When resetting the counterweight 407, the staff's finger contacts the surface of the finger groove 420 and the anti-slip strip 419, and the rotating arc block 416 can return the counterweight 407 to its original position under the action of the return spring 406 and the guidance of the guide rod 405.

[0055] When disassembling the starting mechanism 4 and the hot gas collecting mechanism 5, since there is no fixed connection structure between the starting mechanism 4, the hot gas collecting mechanism 5 and the gas turbine body 3, directly unscrewing the first screw 603 and the second screw 608 can complete the disassembly of the starting mechanism 4 and the hot gas collecting mechanism 5.

[0056] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
