Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to a main airflow blade mounting structure and an indoor unit. Background Technology

[0002] Air conditioners are widely used for regulating indoor ambient temperature. The indoor unit of an air conditioner generally has driven air guide vanes and driven air guide vanes that are rotatably connected to the base. The driven air guide vanes and driven air guide vanes are linked together by a linkage. The base has an adjustment part that can limit the position of the driven air guide vanes after adjusting their air guide angle to ensure the stability of the air guide angle of the driven air guide vanes and driven air guide vanes. However, the driven air guide vanes will wear down the adjustment part during rotation, which will weaken or even lose the limiting effect of the adjustment part on the driven air guide vanes. Consequently, the stability of the air guide angle adjustment of the driven air guide vanes is poor or even fails. Summary of the Invention

[0003] The present invention aims to provide a main air blade mounting structure and an indoor unit to solve the technical problem that the existing main air blades will wear on the adjustment part during rotation, resulting in a weakening or even loss of the limiting effect of the adjustment part on the main air blades.

[0004] To address the aforementioned problems, this invention provides a leading wind turbine blade mounting structure, comprising a leading wind turbine blade, a base, and a detachable fixing seat fixed to the base. The leading wind turbine blade includes a blade and a rotating shaft fixed to the blade. The rotating shaft has a first support portion and a first adjustment portion. The base has a mounting hole, and the fixing seat has a second support portion and a second adjustment portion. The rotating shaft is inserted into the mounting hole. The first support portion and the second support portion are located on the same side of the mounting hole and are spaced apart along the axial direction of the mounting hole. An elastic element connects the first support portion and the second support portion. A single adjustment position of the first adjustment portion is inserted into a single adjustment position of the second adjustment portion, and the insertion direction is consistent with the direction of the second support portion toward the first support portion. One of the adjustment positions of the first adjustment portion and the adjustment positions of the second adjustment portion is multiple and spaced apart circumferentially along the rotating shaft.

[0005] In the main wind turbine blade mounting structure provided by this invention, on the one hand, when the main wind turbine blade is adjusted for airflow angle, the adjustment position of the first adjustment part in the main wind turbine blade is disengaged from the adjustment position of the second adjustment part in the fixed seat. This effectively reduces wear caused by the relative circumferential rotation of the adjustment positions of the first and second adjustment parts, and correspondingly ensures that the adjustment position of the second adjustment part effectively limits the airflow angle of the main wind turbine blade. On the other hand, the fixed seat is detachably mounted on the base as an independent component. When the adjustment position of the second adjustment part wears down, the fixed seat can be disassembled and replaced, thereby improving the ease of maintenance of the main wind turbine blade mounting structure, reducing its maintenance cost, and further ensuring that the adjustment position of the second adjustment part in the fixed seat effectively limits the airflow angle of the main wind turbine blade.

[0006] Optionally, the first support is located between the mounting hole and the second support. The air guide angle can be adjusted by pulling the main air blade outward and rotating it circumferentially.

[0007] Optionally, the first support is located on the side of the second support opposite to the mounting hole. The air guide angle can be adjusted by pressing the main air blade inward and rotating it circumferentially, and the pressing force is easier, thereby improving the convenience of adjusting the air guide angle of the main air blade.

[0008] Optionally, the rotating shaft is provided with a first limiting part, and the base or the fixed seat is provided with a second limiting part. The first limiting part abuts against the second limiting part in the direction of the second supporting part toward the first supporting part. Under the combined action of the second limiting part and the elastic element, the rotating shaft can be stabilized at a certain position in the axial direction, and at this position, the adjustment position of the first adjusting part is inserted into the adjustment position of the second adjusting part, thereby improving the stability of the guide angle of the main wind vane.

[0009] Optionally, the first support portion is located between the mounting hole and the second support portion; the adjustment position of the first adjustment portion includes a limiting head, and the adjustment position of the second adjustment portion includes a limiting groove, wherein there are multiple limiting grooves; the limiting groove is axially connected to the mounting hole, and the limiting groove opens to the side facing the mounting hole; the limiting head abuts against the end face of the mounting hole facing the limiting head; or, the limiting head abuts against the bottom of the limiting groove. Two specific forms of the first adjustment portion, the second adjustment portion, the first limiting portion, and the second limiting portion are provided.

[0010] Optionally, the adjustment position of the first adjustment part includes a limiting head, and the adjustment position of the second adjustment part includes a limiting groove. There are multiple limiting grooves, which are axially connected to the mounting hole and open towards one side of the mounting hole. The mounting hole has an axially connected notch at its edge, corresponding to the first adjustment part and the first support part. When operations such as replacing the main air blade are required, the main air blade can be directly pulled out axially. Similarly, when installing the main air blade, the adjustment position of the first adjustment part of the main air blade is aligned with the limiting groove at the required angle and inserted directly inward to complete the installation, thereby improving the ease of installation and removal of the main air blade.

[0011] Optionally, the mounting base is provided with a insertion hole, the rotating shaft is inserted into the insertion hole, and the annular area of ​​the mounting base surrounding the insertion hole serves as the second support. The insertion hole can guide and limit the shaft section away from the blade, thereby improving the stability of the main wind turbine blades rotating and mounted on the base and mounting base; the annular area at the edge of the insertion hole, as the second support, provides high stability for supporting and compressing the elastic element.

[0012] Optionally, the first support portion includes an annular boss surrounding the pivot. The annular boss surrounds all areas circumferentially around the pivot, thereby ensuring effective support for the elastic element.

[0013] Optionally, the first adjustment part is located on the first support part. Having the first adjustment part located on the first support part provides greater ease of processing and stability.

[0014] The present invention also provides an indoor unit including the aforementioned main air blade mounting structure. This indoor unit possesses all the beneficial effects of the aforementioned main air blade mounting structure, which will not be elaborated further here. Attached Figure Description

Detailed Implementation

[0036] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0037] This embodiment provides a main wind turbine blade mounting structure, such as... Figure 3 and Figure 4 As shown, the device includes a main wind vane 100, a base 10, and a detachable mounting base 200 fixed to the base 10. The main wind vane 100 includes a blade 110 and a rotating shaft 120 fixed to the blade 110. The rotating shaft 120 is provided with a first support portion 130 and a first adjustment portion 140. The base 10 is provided with a mounting hole 11, and the mounting base 200 is provided with a second support portion 210 and a second adjustment portion 220. The rotating shaft 120 is inserted into the mounting hole 11, and the first support portion 130 and the second support portion 210 are located at the mounting hole 11. On the same side of the mounting hole 11 and spaced apart along the axial direction of the mounting hole 11, an elastic element 300 is connected between the first support part 130 and the second support part 210; a single adjustment position of the first adjustment part 140 is fitted into a single adjustment position of the second adjustment part 220, and the insertion direction is consistent with the direction of the second support part 210 toward the first support part 130; of the adjustment positions of the first adjustment part 140 and the adjustment positions of the second adjustment part 220, there are multiple adjustment positions and they are spaced apart along the circumferential direction of the rotating shaft 120.

[0038] The main wind vane mounting structure provided in this embodiment includes a base 10 as a mounting substrate, a main wind vane 100 as an active component for guiding airflow, and a fixing seat 200 for cooperating with the main wind vane 100 to limit its guiding angle. First, the direction from the second support portion 210 toward the first support portion 130 along the axial direction of the rotation axis 120 is defined as the limiting direction, and the direction from the first support portion 130 toward the second support portion 210 is defined as the adjustment direction. Second, the example is given with one adjustment position of the first adjustment portion 140 and multiple adjustment positions of the second adjustment portion 220.

[0039] In the initial state, the dominant wind blade 100 is not subjected to external forces, such as Figure 8 As shown, the adjustment position of the first adjustment part 140 is inserted into one of the adjustment positions of the second adjustment part 220 along the limiting direction. The adjustment position of the first adjustment part 140 cannot rotate circumferentially under the restriction of the adjustment position of the second adjustment part 220, thereby determining the guide angle of the main wind vane 100. When it is necessary to adjust the guide angle of the main wind vane 100, force is applied to the main wind vane 100 along the adjustment direction, such as... Figure 9 As shown, the rotating shaft 120 drives the first adjusting part 140 to move along the adjusting direction and disengage from the adjusting position of the second adjusting part 220. The first support part 130 moves toward the second support part 210 along the adjusting direction with the rotating shaft 120, and the elastic element 300 is compressed. Then, the circumferentially rotating main air blade 100 adjusts it to the required air guiding angle, as shown... Figure 10 As shown, the adjustment position of the first adjustment part 140 corresponds to another adjustment position of the second adjustment part 220, stopping the force applied to the main wind vane 100, and the compressed elastic member 300 applies an elastic restoring force along the limiting direction to the first support part 130, such as... Figure 11 As shown, the first support part 130 drives the rotating shaft 120 and the first adjustment part 140 to move along the limiting direction until the adjustment position of the first adjustment part 140 is inserted into the other adjustment position of the second adjustment part 220 along the limiting direction. The other adjustment position of the second adjustment part 220 limits the main wind vane 100 to the adjusted wind guiding angle by limiting the adjustment position of the first adjustment part 140.

[0040] In this main wind vane mounting structure, on the one hand, when the main wind vane 100 adjusts its guide angle, the adjustment position of the first adjustment part 140 in the main wind vane 100 is disengaged from the adjustment position of the second adjustment part 220 in the fixed seat 200. This effectively reduces wear caused by the relative circumferential rotation of the adjustment positions of the first adjustment part 140 and the second adjustment part 220, and correspondingly ensures that the adjustment position of the second adjustment part 220 effectively limits the guide angle of the main wind vane 100. On the other hand, the fixed seat 200 is detachably mounted on the base 10 as an independent component. When the adjustment position of the second adjustment part 220 wears, the fixed seat 200 can be disassembled and replaced, thereby improving the ease of maintenance of the main wind vane mounting structure, reducing its maintenance cost, and further ensuring that the adjustment position of the second adjustment part 220 in the fixed seat 200 effectively limits the guide angle of the main wind vane 100.

[0041] In addition to the first adjustment part 140 having a single adjustment position and the second adjustment part 220 having multiple adjustment positions, the first adjustment part 140 may also have multiple adjustment positions and the second adjustment part 220 may have a single adjustment position. In the initial state, one of the adjustment positions of the first adjustment part 140 is engaged with the adjustment position of the second adjustment part 220. When it is necessary to adjust the guide angle of the main wind vane 100, the adjustment position of the first adjustment part 140 disengages from the adjustment position of the second adjustment part 220 along the adjustment direction. After the main wind vane 100 rotates circumferentially to the required guide angle, the other adjustment position of the first adjustment part 140 corresponds to the adjustment position of the second adjustment part 220 and moves and engages along the limiting direction to limit the other guide angle of the main wind vane 100.

[0042] Specifically, the adjustment position of the first adjustment part 140 can be a limiting head, and the adjustment position of the second adjustment part 220 can be a limiting groove 221. The number of limiting heads in each adjustment position of the first adjustment part 140 can be one, two, or more. Correspondingly, the number of limiting grooves 221 in each adjustment position of the second adjustment part 220 is equal to and corresponds one-to-one with the number of limiting heads. Similarly, the adjustment position of the first adjustment part 140 can also be a limiting groove 221, and the adjustment position of the second adjustment part 220 can be a limiting head.

[0043] Optionally, such as Figure 13 As shown, the fixing base 200 may be provided with a connecting hole 250 and a positioning hole 240, such as Figures 5-7As shown, the base 10 is provided with a screw post 14 corresponding to the position of the connecting hole 250 and a positioning post 13 matching the positioning hole 240. During installation, the positioning hole 240 can be aligned with the positioning post 13, and then the fixing seat 200 can be moved toward the base 10 until the positioning post 13 is inserted into the positioning hole 240, thereby achieving preliminary positioning of the fixing seat 200 on the base 10, thus improving the positional accuracy and convenience of the connection between the fixing seat 200 and the base 10. Then, a screw is passed through the connecting hole 250 and threaded to the screw post 14 to complete the detachable connection between the fixing seat 200 and the base 10. The screw post 14 is provided on the base 10, which ensures the effective length of the connection between the screw and the base 10, and eliminates the need to drill holes in the base 10, thereby ensuring the sealing, strength and appearance integrity of the base 10.

[0044] This embodiment also provides an indoor unit, such as... Figure 1 and Figure 2 As shown, the indoor unit includes the aforementioned main air blade mounting structure, with the base of the indoor unit serving as the base 10 within this structure. Specifically, multiple guide vanes 30 and the main air blade 100 are arranged along the length of the base, and are connected via a connecting rod 20. The guide angle of the guide vanes 30 is synchronized with that of the main air blade 100 by the linkage of the connecting rod 20. Adjusting the guide angle of the main air blade 100 allows for the synchronized adjustment of the guide angles of all the guide vanes 30. This indoor unit possesses all the beneficial effects of the aforementioned main air blade mounting structure, which will not be elaborated upon here.

[0045] In this embodiment, as Figure 16 As shown, the first support portion 130 is located on the side of the second support portion 210 opposite to the mounting hole 11. Figure 16 Using the mid-angle view as a reference, the adjustment direction is from top to bottom, and the limiting direction is from bottom to top. The blades of the main air blade 100 are located above the rotating shaft 120 (the blades are omitted in the figure). When it is necessary to adjust the air guide angle of the main air blade 100, the main air blade 100 can be pulled outward. The adjustment position of the first adjustment part 140 moves upward with the rotating shaft 120 and disengages from the adjustment position of the second adjustment part 220. The first support part 130 moves toward the second support part 210. The elastic element 300 is compressed under the squeezing action of the first support part 130 and the second support part 210. The main air blade 100 is rotated circumferentially to the required air guide angle, and then the force is stopped. The elastic element 300 drives the first support part 130 to return to its original position downward. The adjustment position of the first adjustment part 140 is inserted downward into the corresponding adjustment position of the second adjustment part 220, thereby completing the adjustment of the air guide angle of the main air blade 100. During the adjustment process, there is no wear between the adjustment position of the first adjustment part 140 and the adjustment position of the second adjustment part 220.

[0046] In this embodiment, as Figure 4 As shown, the first support portion 130 can also be located between the mounting hole 11 and the second support portion 210. Figure 4 With the mid-angle as the reference, the adjustment direction is from top to bottom and the limiting direction is from bottom to top. The blade of the main air blade 100 is located above the rotating shaft 120. When it is necessary to adjust the air guide angle of the main air blade 100, the blade can be pressed down until the adjustment position of the first adjustment part 140 is disengaged from the adjustment position of the second adjustment part 220. The first support part 130 presses down on the elastic member 300, and the elastic member 300 is in a compressed state. Then, the main air blade 100 can be rotated circumferentially to the required air guide angle. The main air blade 100 is released, and the elastic member 300 pushes the first support part 130 to move upward until the adjustment position of the first adjustment part 140 is inserted into the corresponding adjustment position of the second adjustment part 220, thus completing the adjustment of the air guide angle of the main air blade 100. During the adjustment process, the adjustment of the first adjustment part 140 is located between the adjustment positions of the second adjustment part 220 without wear. The above-mentioned settings allow users to adjust the airflow angle of the main airflow blade 100 by pressing it downwards. Compared to pulling the main airflow blade 100 upwards, pressing downwards is easier, thereby improving the convenience of adjusting the airflow angle of the main airflow blade 100.

[0047] In this embodiment, as Figure 5 and Figure 13 As shown, the mounting base 200 is provided with a plug-in hole 230, such as Figure 3 and Figure 4 As shown, the rotating shaft 120 is inserted into the insertion hole 230, and the fixing seat 200 surrounds the annular area of ​​the insertion hole 230 as the second support part 210. On the one hand, the mounting hole 11 can guide and limit the shaft section of the rotating shaft 120 near the blade. When the end of the rotating shaft 120 away from the blade is inserted into the insertion hole 230, the insertion hole 230 can guide and limit the shaft section of the rotating shaft 120 away from the blade, thereby improving the stability of the main wind vane 100 rotating and mounted on the base 10 and the fixing seat 200. Correspondingly, it ensures the positional correspondence between the adjustment of the first adjustment part 140 and the adjustment position of the second adjustment part 220 during the adjustment of the wind guide angle of the main wind vane 100, thereby ensuring the insertion and cooperation of the two. On the other hand, the annular area at the edge of the insertion hole 230 can serve as a second support 210 to support and compress the elastic member 300. During the circumferential rotation of the rotating shaft 120, the annular area can always ensure support and compression of the elastic member 300. Furthermore, the installation of the insertion hole 230 on the fixing seat 200 can achieve the above dual effects simultaneously, without the need to additionally install a boss or the like as a second support 210, thereby effectively simplifying the structure of the fixing seat 200.

[0048] Specifically, such as Figure 13As shown, the fixed base 200 may be provided with an annular reinforcing platform 260 on the side facing the base 10. The insertion hole 230 is located in the inner area of ​​the annular reinforcing platform 260 and the two are coaxially arranged. A portion of the arc-shaped area of ​​the annular reinforcing platform 260 extends outward to form an extension platform, and the side of the extension platform facing the inner ring of the annular reinforcing platform 260 is provided with an arc-shaped skirt. This arc-shaped skirt serves as a second adjustment part 220, and the arc-shaped skirt is provided with a limiting groove 221, which serves as an adjustment position.

[0049] In this embodiment, as Figure 12 As shown, the first support portion 130 may include an annular boss surrounding the rotating shaft 120. This is a specific form of the first support portion 130, wherein the annular boss surrounds the entire circumferential area of ​​the rotating shaft 120, thereby ensuring effective support for the elastic member 300. This, in turn, ensures the stability of the insertion of the elastic member 300 into the adjusting position of the first adjusting portion 140 and the second adjusting portion 220 after the elastic member 300 applies force to the first support portion 130 to drive the guide vane 100 back along the limiting direction, and the stability of the insertion of the adjusting position of the first adjusting portion 140 and the adjusting position of the second adjusting portion 220 after the guide vane 100 returns to its original position. Specifically, the elastic member 300 may be a spring, which is sleeved on the shaft segment of the rotating shaft 120 located between the first support portion 130 and the second support portion 210. One end of the spring abuts against the first support portion 130, and the other end abuts against the second support portion 210.

[0050] In this embodiment, as Figure 12 As shown, the first adjustment part 140 can be disposed on the first support part 130. Compared with the first adjustment part 140 being disposed on the arc-shaped sidewall of the rotating shaft 120, the first adjustment part 140 being disposed on the first support part 130 offers greater ease of processing and stability. When the first support part 130 adopts the aforementioned annular boss and the first adjustment part 140 is disposed on the first support part 130, such as Figure 3As shown, the base 10 extends an arc-shaped boss 12 towards the fixed seat 200. The mounting hole 11 includes a circular hole in the base 10 and a partial hole formed by the arc surface of the arc-shaped boss 12 facing the circular hole. Along the circumference of the circular hole, the area where the arc-shaped boss 12 is located is different from the area where the adjustment position of the second adjustment part 220 is located. The partial hole is coplanar with the circular hole, and the arc surface of the partial hole matches the annular boss, thereby guiding and limiting the circumferential rotation (i.e., axial movement) of the rotating shaft 120 by the mounting hole 11. Furthermore, a notch 16 can be provided on one side of the circular hole for the first adjustment part 140 to pass through. When installing the main air blade 100, the first adjustment part 140 can be aligned with the notch 16, and the rotating shaft 120 can be inserted into the mounting hole 11. Then, the rotating shaft 120 can be rotated circumferentially to align the adjustment position of the first adjustment part 140 with the adjustment position of the second adjustment part 220, thus limiting their insertion. Similarly, when it is necessary to disassemble the main air blade 100, the adjustment position of the first adjustment part 140 can be axially disengaged from the adjustment position of the second adjustment part 220. Then, the rotating shaft 120 can be rotated circumferentially to align the first adjustment part 140 with the notch 16, and then the main air blade 100 can be pulled outward.

[0051] In this embodiment, as Figure 14As shown, the adjustment position of the first adjustment part 140 includes a limiting head, and the adjustment position of the second adjustment part 220 includes a limiting groove 221. Multiple limiting grooves 221 are provided, which are axially connected to the mounting hole 11 and open towards the side of the mounting hole 11. The edge of the mounting hole 11 has a notch 15 axially connected to it, which corresponds to the first adjustment part 140 and the first support part 130. When this structure is applied to an indoor unit, since the guide vane 30 is rotatably connected to the base 10, in use, the guide vane 30 can restrict the axial position of the main air vane 100 through the connecting rod 20. The rotating shaft 120 is held at a certain axial position under the limiting action of the elastic element 300 and the connecting rod 20. At this position, the limiting head is inserted into the limiting groove 221, thereby limiting the air guiding angle of the main air vane 100. When it is necessary to adjust the air guide angle of the main air blade 100, the main air blade 100 can be pushed along the axial direction. The connecting rod 20 can undergo a certain degree of plastic bending deformation due to the pull of the main air blade 100. When the main air blade 100 is rotated to adjust the air guide angle, the connecting rod 20 drives the air guide blade 30 to adjust the air guide angle synchronously. After completion, stop applying force to the main air blade 100. Under the restoring action of the elastic element 300 and the connecting rod 20, the main air blade 100 returns to the initial axial position, and the limiting head is correspondingly inserted into another limiting groove 221. When it is necessary to replace the main air blade 100, the connection between the main air blade 100 and the connecting rod 20 can be disassembled. Since the notch 15 on the edge of the mounting hole 11 corresponds to the first adjustment part 140 and the first support part 130, the main air blade 100 can be pulled out axially. Similarly, when installing the main air blade 100, the adjustment position of the first adjustment part 140 in the main air blade 100 is aligned with the limiting groove 221 of the required angle and inserted directly into it to complete the installation of the main air blade 100, thereby improving the ease of disassembly and assembly of the main air blade 100.

[0052] Furthermore, the machining of the through-hole limiting groove 221 in the fixed seat 200 has lower machining requirements, thereby improving the machining convenience of the fixed seat 200 and reducing machining costs.

[0053] Optionally, in this embodiment, as Figure 4As shown, the rotating shaft 120 is provided with a first limiting part 150, and the base 10 or the fixed seat 200 is provided with a second limiting part 400. The first limiting part 150 abuts against the second limiting part 400 in the direction of the second support part 210 toward the first support part 130. When the main wind vane 100 is not subjected to external force, the second limiting part 400 can restrict the rotating shaft 120 to move in the limiting direction by abutting against the first limiting part 150, and the elastic member 300 can restrict the rotating shaft 120 to move in the adjusting direction by abutting against the first support part 130. Then, under the combined action of the second limiting part 400 and the elastic member 300, the rotating shaft 120 can be stabilized at a certain position in the axial direction, and at this position, the adjusting position of the first adjusting part 140 is inserted into the adjusting position of the second adjusting part 220, thereby improving the stability of the wind guiding angle of the main wind vane 100. In addition, compared with the above-mentioned structure of the main wind vane 100 which is easy to disassemble and assemble, in this embodiment, the second limiting part 400 in the base 10 or the fixed base 200 can restrict the rotating shaft 120 to move outward by the first limiting part 150, thereby reducing the force of the main wind vane 100 on the connecting rod 20, thus ensuring the normal use of the connecting rod 20 and reducing the occurrence of the connecting rod 20 being easily bent or even broken due to long-term stress.

[0054] Specifically, in this embodiment, as Figure 15 As shown, the first support part 130 is located between the mounting hole 11 and the second support part 210; the adjustment position of the first adjustment part 140 includes a limiting head, and the adjustment position of the second adjustment part 220 includes a limiting groove 221, and there are multiple limiting grooves 221; the limiting groove 221 is provided through the axial direction of the mounting hole 11, and the limiting groove 221 is opened on the side facing the mounting hole 11; the limiting head abuts against the end face of the mounting hole 11 facing the limiting head. This is a specific form of the main wind turbine blade mounting structure. When the main wind turbine blade 100 is not subjected to external force, the limiting head is inserted into the limiting groove 221 to limit the circumferential angle of the rotating shaft 120. At the same time, the limiting head abuts against the end face of the mounting hole 11 to limit the axial position of the rotating shaft 120. Thus, the limiting head serves as both the adjustment position of the first adjustment part 140 and the first limiting part 150, serving two purposes in one. While ensuring the performance of the main wind turbine blade 100, this effectively simplifies the structure of the main wind turbine blade 100, improves its processing convenience, and reduces its processing cost. In addition, the area at the edge of the mounting hole 11 serves as the second limiting part 400, providing high limiting stability for the limiting head, and eliminating the need for additional structures such as bosses on the base 10 as the second limiting part 400, thereby improving the structural simplicity of the base 10.

[0055] In addition to the through-type described above, in some embodiments, the limiting groove 221 may also have other forms, such as... Figure 16As shown, it can also be a non-through groove form. When the main wind vane 100 is not subjected to external force, the limiting head abuts against the bottom of the limiting groove 221. At this time, the limiting groove 221 can simultaneously restrict the circumferential movement of the limiting head and the axial movement along the limiting direction. Then, the limiting head simultaneously serves as the adjustment position of the first adjustment part 140 and the first limiting part 150. Correspondingly, the limiting groove 221 simultaneously serves as the adjustment position of the second adjustment part 220 and the second limiting part 400.

[0056] The following describes some specific structural elements of the main wind turbine blade installation structure:

[0057] Please see Figure 4 ,by Figure 4 Using the mid-angle view as a reference, the downward direction is the limiting direction, and the upward direction is the adjusting direction. The rotating shaft 120 is inserted into the mounting hole 11 and the insertion hole 230. The mounting hole 11 and the insertion hole 230 respectively guide and limit the upper and lower shaft sections of the rotating shaft 120. The first support part 130 is located between the mounting hole 11 and the second support part 210. The elastic element 300 is a spring sleeved on the rotating shaft 120. The first support part 130 adopts an annular boss, and the annular area of ​​the insertion hole 230... The area serves as the second support part 210, with the spring supporting it between the annular boss and the upper end face of the insertion hole 230; the first adjustment part 140 adopts a limiting head, which is located on the annular boss; the second adjustment part 220 adopts a vertically penetrating limiting groove 221, with the limiting head inserted into the limiting groove 221, and the top of the limiting head abutting against the lower end face of the mounting hole 11. That is, the limiting head also serves as the first limiting part 150, and the annular area at the edge of the mounting hole 11 serves as the second limiting part 400. When it is necessary to adjust the air guide angle of the main air blade 100, press down on the rotating shaft 120 until the limiting head disengages downward from the limiting groove 221, and the spring is compressed. Rotate the rotating shaft 120 circumferentially to the desired angle, and then stop applying force to the rotating shaft 120. The spring drives the rotating shaft 120 to move upward by applying force to the annular boss. The limiting head is inserted into another limiting groove 221 and abuts against the lower end face of the mounting hole 11 again, thereby completing the adjustment of the air guide angle of the main air blade 100.

[0058] certainly, Figure 4 In addition to the aforementioned annular boss, the first support portion 130 can also be a support boss protruding from the rotating shaft 120. The first adjustment portion 140 includes a limiting head and a connecting arm connecting the limiting head and the rotating shaft 120. The limiting head serves as both the adjustment position of the first adjustment portion 140 and the first limiting portion 150.

[0059] Please see Figure 14 ,by Figure 14Using the mid-angle as a reference, the bottom-up direction is the limiting direction, and the top-down direction is the adjustment direction. An arc-shaped boss 12 extends downwards from the bottom surface of the base 10. The mounting hole 11 includes a circular hole in the base 10 and a partial hole formed by the inner arc surface of the arc-shaped boss 12. The rotating shaft 120 is inserted into the mounting hole 11 and the insertion hole 230. The first support part 130 is located between the mounting hole 11 and the second support part 210. The elastic element 300 is a spring sleeved on the rotating shaft 120. The first support part 130 is an annular boss, and the annular area of ​​the insertion hole 230 serves as... The second support part 210 is spring-supported between the annular boss and the upper end face of the insertion hole 230; the mounting hole 11 guides and limits the upper shaft section of the rotating shaft 120 by cooperating with the annular boss, and the insertion hole 230 guides and limits the lower shaft section of the rotating shaft 120; the first adjustment part 140 adopts a limiting head, which is located on the annular boss; the second adjustment part 220 adopts a limiting groove 221 that is vertically through and open on the side, and the limiting head is inserted into the limiting groove 221; the base 10 and the corresponding area of ​​the limiting groove 221 are provided with a through notch 15. When adjusting the airflow angle of the main airflow blade 100, press down on the rotating shaft 120 until the limiting head disengages downward from the limiting groove 221, and the spring is compressed. Rotate the rotating shaft 120 circumferentially to the desired angle, and then stop applying force to the rotating shaft 120. The spring drives the rotating shaft 120 upward by applying force to the annular boss, and the limiting head inserts into another limiting groove 221, thus completing the adjustment of the airflow angle of the main airflow blade 100. When it is necessary to disassemble or assemble the main airflow blade 100, simply pull it out upward or insert it downward; the disassembly and assembly are highly convenient.

[0060] Please see Figure 15 , Figure 15 Compared Figure 4 The difference is that the side wall of the rotating shaft 120 does not have an additional boss as the first support part 130. The side wall of the rotating shaft 120 is provided with a limiting head and a connecting arm connecting the rotating shaft 120 and the limiting head. After the connecting arm and the limiting head are connected, they simultaneously serve as the first adjustment part 140, the first limiting part 150 and the first support part 130. The limiting head is used as the adjustment of the first adjustment part 140, and is inserted into the limiting groove 221.

[0061] Please continue reading Figure 16 , Figure 16 Compared Figure 4The difference lies in that the adjustment position of the second adjustment part 220 adopts a non-through limiting groove 221, and the limiting head is inserted into the limiting groove 221 from bottom to top, and the top surface of the limiting head abuts against the bottom of the limiting groove 221. Thus, the limiting head serves as both the adjustment position of the first adjustment part 140 and the first limiting part 150. In addition to serving as the adjustment position of the second adjustment part 220, the limiting groove 221 also serves as the second limiting part 400. Furthermore, the difference also includes that the fixed base 200 does not have a plug hole 230, but instead has an extension boss as the second support part 210 to support the spring.

[0062] Please see Figure 17 , Figure 17 Compared Figure 15 The difference lies in that the first support part 130 is located on the side of the second support part 210 away from the mounting hole 11. Therefore, the direction from top to bottom is the limiting direction, and the direction from bottom to top is the adjusting direction. The spring supports the first support part 130 between the lower end face of the insertion hole 230, and the annular area at the edge of the insertion hole 230 serves as the second support part 210. The lower end face of the limiting head abuts against the upper end face of the insertion hole 230, and the annular area at the edge of the insertion hole 230 simultaneously serves as the second limiting part 400. When it is necessary to adjust the airflow angle of the main airflow blade 100, the rotating shaft 120 can be pulled upwards axially until the limiting head disengages upwards from the limiting groove 221, and the spring is compressed. The rotating shaft 120 is rotated circumferentially to the desired angle, and then the force applied to the rotating shaft 120 is stopped. The spring, through the force applied to the first support part 130, drives the rotating shaft 120 downwards, and the limiting head inserts into another limiting groove 221, thereby completing the adjustment of the airflow angle of the main airflow blade 100.

[0063] Please continue reading Figure 18 , Figure 18 Compared Figure 17 The difference is that the limiting groove 221 of the second adjustment part 220 adopts a non-through form. When the limiting head is inserted into the limiting groove 221, the lower end face of the limiting head abuts against the bottom of the limiting groove 221. Then the limiting head serves as both the adjustment position of the first adjustment part 140 and the first limiting part 150, and the limiting groove 221 serves as both the adjustment position of the second adjustment part 220 and the second limiting part 400.
