[0028] The following disclosure provides many different implementations or examples for carrying out different structures of this application. To simplify the disclosure of this application, the components and arrangements of specific examples are described below. Of course, these are merely examples and are not intended to limit this application.

[0029] A turbine relies on an input gas at a certain pressure and temperature to drive its internal impeller, thereby converting energy and outputting mechanical work. As the fluid flows through the nozzle ring 100, it is accelerated and its flow direction is adjusted before impacting the impeller blades 120, causing the rotor to rotate. This, in turn, drives the turbine shaft to rotate, which in turn drives other machinery directly or via a transmission mechanism, outputting mechanical work. During operation, adjusting the spacing between the turbine blades 120 allows the turbine to adapt to different working conditions and achieve higher efficiency.

[0030] However, due to the limited space inside the turbine, it is difficult to install the drive assembly 300 that drives the blades 120 to rotate inside the turbine.

[0031] To address the technical challenge of fitting the drive assembly 300 inside the turbine, please refer to [link / reference needed]. Figure 1 and Figure 2 The first embodiment of this application provides a turbine, which includes a nozzle ring 100, a first transmission assembly 200, and a drive assembly 300. The first transmission assembly 200 includes a first shaft 210, a universal joint 220, and a second shaft 230 connected in sequence. The first shaft 210 is connected to the nozzle ring 100. The drive assembly 300 is connected to the second shaft 230 and can drive the first transmission assembly 200 to rotate so as to drive the blades 120 in the nozzle ring 100 to rotate.

[0032] Specifically, by rotating the blades 120 in the nozzle ring 100, the flow cross-sectional area of ​​the space formed between adjacent blades 120 is changed.

[0033] In the above embodiment, the turbine is configured with a first transmission component 200 so that the drive component 300 and the nozzle ring 100 can be spaced apart, and the first transmission component 200 transmits power between the drive component 300 and the nozzle ring 100, thereby increasing the range of selectable positions for the drive component 300 and reducing the difficulty of setting the drive component 300.

[0034] It is understood that by setting the universal joint 220, the first shaft 210 and the central axis of the second shaft 230 can intersect, and power can still be transmitted between the first shaft 210, the universal joint 220 and the second shaft 230. Therefore, in the above embodiment, by setting the first transmission assembly 200 with the universal joint 220, the difficulty of arranging the drive assembly 300 and the first transmission assembly 200 can be further reduced.

[0035] In some embodiments, the drive component 300 may be a motor that outputs torque or an electric cylinder that outputs force.

[0036] In some embodiments, please refer to Figure 1 The drive assembly 300 includes a link 310, which is connected to the end of the second shaft 230 away from the universal joint 220. The link 310 is connected to the drive assembly 300, and a portion of the drive assembly 300 is capable of linear motion to drive the link 310 to rotate.

[0037] Firstly, in the above embodiments, by setting the connecting rod 310, the drive assembly 300 can be further moved away from the nozzle ring 100, which facilitates the setting of the drive assembly 300.

[0038] Secondly, by setting the connecting rod 310, the torque required to rotate the first transmission component 200 can be reduced, making the selection range of the drive component 300 wider.

[0039] In some embodiments, please refer to Figure 1 and Figure 12 The connecting rod 310 has a groove 311 extending along a first direction M. The drive assembly 300 also includes a fixed part and a drive part connected to each other. The drive part is movable relative to the fixed part along a second direction N. A portion of the drive part is disposed in the groove 311 and is slidable relative to the connecting rod 310 along the first direction M.

[0040] In the above embodiment, by providing the slide groove 311, the drive assembly 300 moves the drive part along the second direction N and moves the drive part along the slide groove 311 along the second direction N to drive the connecting rod 310 to rotate, thereby converting the force output by the drive assembly 300 into a torque that can rotate the first transmission assembly 200, further expanding the selection range of the drive assembly 300 and facilitating the selection of the drive assembly 300.

[0041] In some embodiments, please refer to Figure 1 , Figure 5 and Figure 6 The nozzle ring 100 includes a base 110, a plurality of blades 120, and a second transmission assembly 130. The plurality of blades 120 are arranged at circumferential Y intervals along the base 110. Each blade 120 includes a body portion 121 and a rotating portion 122. The rotating portion 122 is rotatably disposed through the base 110. The second transmission assembly 130 is disposed on the side of the base 110 away from the body portion 121 and is connected to the rotating portion 122. The second transmission assembly 130 is connected to a first transmission assembly 200. The first transmission assembly 200 can drive the second transmission assembly 130 to rotate, thereby rotating the rotating portion 122.

[0042] Specifically, the first transmission component 200 can transmit torque from the self-driving component 300 to the second transmission component 130 to drive the second transmission component 130 to rotate. The rotation of the second transmission component 130 can drive the rotating part 122 to rotate, thereby rotating the blade 120.

[0043] In some embodiments, the second transmission component 130 engages with the rotating part 122, and the second transmission component 130 can drive the blades 120 to rotate by rotating, thereby changing the spacing between the blades 120.

[0044] In the above embodiment, by setting the second transmission component 130 to receive torque from the first transmission component 200 and achieve rotation, the torque is transmitted to multiple blades 120, thereby achieving synchronous rotation of multiple blades 120 and facilitating the adjustment of the blade angle in the nozzle ring 100.

[0045] In some embodiments, please refer to Figure 4 , Figure 7 and Figure 10The second transmission assembly 130 includes a plurality of first connectors 131, a plurality of guide wheels 132, and a second connector 134. The connectors are disposed on the side of the base 110 away from the main body 121 and are connected to the rotating part 122. The guide wheels 132 have guide grooves 133 on their circumferential sides. The plurality of guide wheels 132 are spaced apart along the circumferential Y direction and are rotatably connected to the side of the base 110 away from the main body 121. The second connectors 134 are disposed around the plurality of rotating parts 122. The second connectors 134 are disposed in the guide grooves 133 of the plurality of guide wheels 132 and are spaced apart from the base 110 along the axial Z direction. The plurality of first connectors 131 are connected to the second connectors 134. The second connectors 134 are connected to the first transmission assembly 200. The first transmission assembly 200 can drive the second connectors 134 to rotate relative to the base 110, thereby driving the first connectors 131 to rotate.

[0046] Specifically, the first transmission assembly 200 drives the second connector 134 to rotate, and the second connector 134 drives one end of the first connector 131 disposed in the guide groove 133 to rotate relative to the other end, so as to drive the blade 120 connected to the first connector 131 to rotate.

[0047] In some embodiments, please refer to Figure 9 The blade 120 also includes a connecting portion 124, which is a non-cylindrical prism capable of transmitting torque, such as a triangular prism, square prism, pentagonal prism, hexagonal prism, etc. One end of the first connecting member 131 has a connecting hole 138, the connecting portion 124 passes through the connecting hole 138, and the hole wall of the connecting hole 138 surrounds the connecting portion 124 and fits against the connecting portion 124 to cooperate with the connecting portion 124 and transmit torque.

[0048] In the above embodiment, by providing a guide wheel 132 with a guide groove 133 on its circumferential side, the second connecting member 134 can be supported and spaced apart from the base 110. This reduces the large frictional force generated when the second connecting member 134 rotates relative to the base 110, and reduces the torque required to adjust the angle of the blade 120, making the operation of the nozzle ring 100 smoother. Furthermore, the second connecting member 134 can rotate relative to the base 110 through rolling friction with the guide wheel 132, reducing the frictional force between the second connecting member 134 and the components supporting it, further reducing the torque required to adjust the angle of the blade 120, making the operation of the nozzle ring 100 smoother.

[0049] In some embodiments, please refer to Figure 4 The second connector 134 has a plurality of positioning grooves 135 on the side facing the rotating part 122. One end of the plurality of first connectors 131 is connected to the rotating part 122, and the other end of the plurality of first connectors 131 is disposed in the positioning groove 135.

[0050] Specifically, when the second connector 134 rotates, the groove wall of the positioning groove 135 will contact the end of the first connector 131 away from the connecting part 124, and push the end of the first connector 131 away from the connecting part 124 to move and rotate relative to the end connected to the connecting part 124, thereby driving the blade 120 to rotate.

[0051] In the above embodiment, by providing multiple positioning grooves 135 in the second connector 134 and placing a portion of the first connector 131 in the positioning grooves 135, it is possible to enable one second connector 134 to drive multiple blades 120 to rotate, thereby reducing the difficulty of driving multiple blades 120 to rotate synchronously.

[0052] In some embodiments, along the direction from the connecting portion 124 to the positioning groove 135, the width of the first connector 131 first decreases and then increases to form a clearance groove, reducing the possibility of interference between the first connector 131 and the second connector 134 when the first connector 131 moves. The width dimension is the dimension of the first connector 131 in the direction perpendicular to the axial direction Z.

[0053] In some embodiments, please refer to Figure 4 and Figure 10 The second transmission assembly 130 also includes a first engaging member 136 and a spacer 137. The first engaging member 136 is spaced apart on the side of the second connecting member 134 away from the base 110, and the first engaging member 136 can engage with the first shaft 210. The spacer 137 is disposed between the second connecting member 134 and the first engaging member 136, and connects the second connecting member 134 and the first engaging member 136 respectively.

[0054] It is understandable that, due to the large number of blades 120 in the nozzle ring 100, the number of first connecting members 131 corresponding to the blades 120 is also large, and the spacing between adjacent first connecting members 131 is small, making it difficult to provide space for the connection between the second connecting member 134 and the first transmission assembly 200. In the above embodiment, by providing a spacer 137, the first engaging member 136 and the base 110 are spaced apart along the axial direction Z, thereby facilitating the first transmission shaft to bypass the first connecting member 131 and connect with the second connecting member 134.

[0055] In some embodiments, please refer to Figure 1 The base 110 has a central shaft 111, and along the radial direction X of the base 110, the first shaft 210 is located on the side of the first engaging member 136 near the central shaft 111.

[0056] In the above embodiment, by placing the first shaft 210 on the side of the first engagement member 136 close to the central shaft 111, the influence of the first transmission assembly 200 on the radial X dimension of the turbine is reduced, allowing the turbine to have a smaller external dimension.

[0057] In some embodiments, the turbine further includes a first housing and a second housing. The first housing has a first receiving cavity and a first through hole communicating with the first receiving cavity, and a first shaft 210 passes through the first through hole. The second housing has a second receiving cavity and a second through hole communicating with the second receiving cavity. The first housing is disposed in the second receiving cavity, the second shaft 230 passes through the second through hole, and a universal joint 220 is disposed in the second receiving cavity.

[0058] In the above embodiments, by passing the first transmission component 200 through the first housing and the second housing, the drive component 300 can be disposed outside the first housing and the second housing, further reducing the size of the first housing and the second housing. Simultaneously, since the first transmission component 200 needs to pass through both the first through hole and the second through hole, and the universal joint 220 provided in the first transmission component 200 allows for a certain angle between the central axis of the first shaft 210 and the central axis of the second shaft 230, that is, it allows for a larger coaxiality tolerance between the first through hole and the second through hole, reducing the machining difficulty of the first housing and the second housing.

[0059] In some embodiments, please refer to Figure 8 The first shaft 210 includes a main body 211, a second engagement part 212, and a first positioning part 213; the second engagement part 212 is connected to the main body 211 and engages with the first transmission assembly 200; the first positioning part 213 surrounds the main body 211 and can contact the first housing to limit the main body 211 along the axial direction Z of the base 110.

[0060] In some embodiments, please refer to Figure 2 The first shaft 210 is fitted with a first bearing 260 at the end away from the connecting rod 310 to reduce the resistance when the first shaft 210 rotates relative to the wall of the first through hole.

[0061] In some embodiments, please refer to Figure 1 The first engaging member 136 and the second engaging part 212 engage.

[0062] In the above embodiment, the first positioning part 213 can contact the first housing, thereby realizing the positioning of the first shaft 210 along the axial direction Z by the first housing, and preventing the first shaft 210 from moving along the axial direction Z during operation.

[0063] In some embodiments, please refer to Figure 1 and Figure 3The first transmission assembly 200 further includes a first seal 240 and a second seal 250. The first seal 240 is sleeved on the first shaft 210 and disposed between the first shaft 210 and the wall of the first through hole, respectively sealing and connecting the first shaft 210 and the wall of the first through hole. The second seal 250 is sleeved on the second shaft 230 and disposed between the second shaft 230 and the wall of the second through hole, respectively sealing and connecting the second shaft 230 and the wall of the second through hole.

[0064] In the above embodiments, by providing a first seal 240 and a second seal 250, the sealing performance of the turbine can be improved. The first seal 240 can reduce the flow of high-pressure gas in the second housing into the low-pressure first receiving cavity through the first through hole; the second seal 250 can reduce the leakage of high-pressure gas in the second receiving cavity, thereby improving the turbine's performance.

[0065] In some embodiments, please refer to Figure 11 The second shaft 230 includes a third positioning part 231, and a second bearing 270 can be sleeved on the third positioning part 231 to reduce the resistance when the second shaft 230 rotates relative to the wall of the second through hole.

[0066] In some embodiments, please refer to Figure 5 The turbine also includes a third seal 600, which is sleeved on the nozzle ring 100 and disposed between the first housing and the nozzle ring 100, respectively sealingly connecting the first housing and the nozzle ring 100.

[0067] Specifically, the third seal 600 is fitted onto the base 110 of the nozzle ring 100.

[0068] In the above embodiment, by providing a third seal 600, the high-pressure gas ejected from the nozzle ring 100 can be reduced from entering the low-pressure first receiving cavity.

[0069] In some embodiments, please refer to Figure 5 The base 110 has multiple third through holes 112, and multiple rotating parts 122 pass through the third through holes 112. The base 110 has a countersunk groove 113 on the side facing the body part 121. The countersunk groove 113 surrounds the third through holes 112 and communicates with the third through holes 112. The blade 120 also includes a second positioning part 123. The second positioning part 123 is disposed between the body part 121 and the rotating part 122 and connects the body part 121 and the rotating part 122 respectively. The second positioning part 123 is disposed in the countersunk groove 113. Along the axial direction Z of the base 110, the orthographic projection of the rotating part 122 on a plane is located within the orthographic projection of the body part 121 on the same plane.

[0070] In the above embodiment, by setting the second positioning part 123 and placing the second positioning part 123 in the countersunk groove 113, it can replace the blade 120 in contact with the base 110, thereby achieving the limitation of the blade 120 along the axial Z. At the same time, under the premise that the blade 120 has achieved axial Z positioning, it can avoid the friction between the larger body part 121 and the base 110 when the blade 120 rotates, and allow the blade 120 to rotate more smoothly.

[0071] Accordingly, this application also provides a power generation device, including a turbine as described in any of the above embodiments.

[0072] Accordingly, this application also provides a method for adjustment, comprising: Calculate the ratio of the turbine load to the turbine's rated load; When the ratio increases, the drive component 300 operates, increasing the spacing between adjacent blades 120; When the ratio decreases, the drive assembly 300 operates, reducing the spacing between adjacent blades 120.

[0073] In some embodiments, the ratio of the load to the turbine's rated load is calculated every preset time interval; if the ratio is equal to the previous ratio, the blade 120 remains stationary; if the ratio is greater than the previous ratio, the drive assembly 300 operates, rotating the blade 120 and increasing the spacing between adjacent blades 120, thereby increasing the flow cross-sectional area between adjacent blades 120; if the ratio is less than the previous ratio, the drive assembly 300 operates, rotating the blade 120 and decreasing the spacing between adjacent blades 120, thereby decreasing the flow cross-sectional area between adjacent blades 120.

[0074] The rated load of the turbine can be found by looking up the turbine's model number, and the load is calculated by reading the power output of the generator that drives the turbine.
