Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of solar power generation, especially to a heliostat rotary speed reducer and heliostat. BACKGROUND

[0002] Tower type solar thermal power generation is to gather sunlight to a central heat exchanger (heat absorber) on the top of the tower by using a large number of directional reflectors (heliostat), and to generate electricity by heating the fluid inside to drive the turbine to rotate. The heliostat tracking function is realized by the rotation of two angles of the pitch angle and the azimuth angle. The heliostat azimuth angle rotation is generally driven by a rotary speed reducer.

[0003] In order to meet the fluency of the heliostat rotation, a deep groove ball bearing is generally arranged between the output end of the rotary speed reducer and the base.

In addition, the deep groove ball bearing with poor axial load capacity is prone to damage, thereby affecting the rotation accuracy of the heliostat under wind resistance conditions, causing the light spot offset to exceed the design requirement, and affecting the power generation efficiency.

Without more limitations, the element defined by the statement "comprising a" does not exclude the existence of additional identical elements in the process, method, article, or apparatus including the element.

[0049] In the present application, the term "and / or", is a description of an associated relationship with associated objects, which means that there can be three kinds of relationships. For example, A and / or B, can represent: the existence of A alone, the existence of A and B together, and the existence of B alone. In addition, the character " / " in the present application generally indicates that the front and rear associated objects are in a "and / or" relationship.

Among them, for example, direct connection refers to the connection of two parts or components without the need for an intermediate part, while indirect connection refers to the connection of two parts or components with at least one intermediate part. In addition, "connection" and "coupling" are not limited to physical or mechanical connection or coupling, and can include electrical connection or coupling.

[0051] In the present application, those of ordinary skill in the art will understand that the relative terms used in connection with quantities or conditions (for example, "about", "approximately", "substantially" and the like) include the values described and have the meaning indicated by the context. For example, the relative terms at least include the degree of error related to the measurement of a specific value, the tolerance caused by manufacturing, assembly, use, etc. related to a specific value.

[0054] Example 1

[0055] like Figures 1 to 3 As shown, this embodiment provides a heliostat rotary reducer, which includes a base 100; a housing 200 mounted on the base 100 and rotatable relative to the base 100; a worm gear 310 with one end fixedly mounted on the base 100 along the axial direction and the other end passing through the housing 200 along the axial direction; a worm 320 rotatably mounted on the housing 200 and meshing with the worm gear 310; a drive member 330 mounted on the housing 200 and its rotation output end being connected to the worm 320; and a tapered roller bearing 400 mounted between the housing 200 and the worm gear 310, with the axis of the tapered roller bearing 400 parallel to the axis of the worm gear 310.

[0056] In the aforementioned configuration, a tapered roller bearing 400 is installed between the worm gear 310 and the housing 200. This allows the housing 200 to rotate smoothly while, compared to deep groove ball bearings, the tapered roller bearing 400 has higher rigidity and strength, is more wear-resistant, reduces the risk of damage, and ensures the rotational stability of the heliostat under wind resistance conditions. This ensures that the beam offset is within the design requirements, guaranteeing power generation efficiency. Furthermore, during assembly, the tapered roller bearing 400 can be axially clamped, thereby improving the structural compactness of the heliostat rotary reducer.

[0057] For details, please refer to the appendix. Figure 2As shown, generally, the base 100 is fixedly arranged on the column 1000 through a connecting member, which is one of a bolt, a screw, a bolt, a rivet or other connecting structure, which is not limited here; and the box body 200 is rotatably arranged on the base 100, and the main function of the box body 200 is to mount the reflector assembly 50 of the heliostat, so as to realize the adjustment of the azimuth angle (i.e. the direction) of the reflector assembly 50 through the rotation of the box body 200. Of course, the base 100 can not only be arranged on the column 1000, but the specific mounting mode can be designed according to the actual situation; generally, the driving member 330 provides the driving force required for the rotation of the box body 200, and the transmission of the driving force is completed through the combination of the worm wheel 310 and the worm 320; in the embodiment of the present scheme, one side of the box body 200 is provided with an open accommodating groove, which is used to accommodate other components of the heliostat rotary reducer, so as to realize the protection of the components; the opening of the accommodating groove on the box body 200 faces the base 100, one end of the worm wheel 310 in the axial direction is fixedly arranged on the base 100, and the other end penetrates the accommodating groove, the worm 320 is rotatably arranged in the box body 200, and the worm 320 is engaged with the worm wheel 310, so as to realize that when the worm 320 rotates, the box body 200 is driven to rotate around the axis of the worm wheel 310, and the tapered roller bearing 400 is arranged between the box body 200 and the worm wheel 310, and the axis of the tapered roller bearing 400 is parallel to the axis of the worm wheel 310.

[0058] In order to facilitate the connection with the heliostat, in some embodiments, the box body 200 comprises a rotating part 210 and a connecting part 220, the rotating part 210 is rotatably arranged on the base 100, the connecting part 220 is arranged at the top end of the rotating part 210 and is located on the side of the rotating axis of the rotating part 210, and the connecting part 220 is used to support the heliostat. This kind of arrangement makes the heliostat girder support 1200 can be connected with the connecting part 220, and placed on the top of the rotating part 210. Of course, in other embodiments, the connecting part 220 can not be located on the side of the rotating axis of the rotating part 210, such as the connecting part 220 is located on the rotating axis of the rotating part 210, which is not limited here, and the specific design can be made according to the actual use. Preferably, the connecting part 220 is arranged at the top end of the rotating part 210 and located on the side of the rotating axis of the rotating part 210.

[0059] Further, the rotating part 210 and the connecting part 220 are designed integrally or detachably connected to adapt to different application scenarios or replace different connecting parts 220 to adapt to different mounting frames. In the embodiment of the present scheme, the integral design between the rotating part 210 and the connecting part 220 can be integrally formed during casting, or the rotating part 210 and the connecting part 220 can be welded, which is not limited here, and the specific design can be made according to the actual situation.

[0060] Regarding the axial clamping of the tapered roller bearing 400, the housing 200 also includes a clamping member 500, which is detachably disposed in the housing 200. The clamping member 500 is configured to clamp the tapered roller bearing 400 axially to adjust the preload of the tapered roller bearing 400 during installation.

[0061] Specifically, see attached Figures 2-3 As shown, under normal circumstances, the worm gear 310 has an annular structure, and its central through hole presents an annular stepped groove 311 structure. The inner ring of the tapered roller bearing 400 is mounted on the housing 200, and the outer ring of the tapered roller bearing 400 is mounted on the worm gear 310. The top of the outer ring of the tapered roller bearing 400 abuts against the top of the annular stepped groove 311, and the abutting part of the clamping member 500 abuts against the bottom of the inner ring of the tapered roller bearing 400. The clamping member 500 ensures that, along the axial direction of the tapered roller bearing 400, the housing 200 and the tapered roller bearing 400, as well as the tapered roller and the worm gear 310, can be clamped together, preventing gaps and improving the compactness of the structure. Of course, in other embodiments of this solution, the annular stepped groove 311 of the central through hole of the worm gear 310 may not face the base 100, or the annular step of the central through hole of the worm gear 310 may face away from the base 100 (i.e., the attached...). Figures 2-3 The annular stepped groove 311 in the worm gear 310 is inverted (the larger radius part is located at the top, and the smaller radius part is located at the bottom). The bottom end of the outer ring of the tapered roller bearing 400 abuts against the bottom of the annular stepped groove 311. The top of the rotating part 210 of the housing 200 is provided with a clamping groove with an opening facing away from the base 100. The clamping member 500 is inserted into the housing 200 from the top clamping groove of the rotating part 210, and the abutting part of the clamping member 500 abuts against the top end of the inner ring of the tapered roller bearing 400, thereby achieving axial clamping of the tapered roller bearing 400. The specific setting of the clamping member 500 can be designed according to the actual situation, as long as the clamping member 500 can clamp the tapered roller bearing 400 axially. Most preferably, the annular stepped groove 311 of the central through hole of the worm gear 310 faces the base 100.

[0062] In particular, in the above embodiments, the conical roller bearing 400 is arranged in the annular stepped groove 311 in the middle of the worm wheel 310. In some specific embodiments, the conical roller bearing 400 can not be arranged on the inner side of the worm wheel 310, and the worm wheel 310 can not have a through hole (i.e., the worm wheel 310 is not an annular structure); at this time, the conical roller bearing 400 can be arranged on the outer side of the worm wheel 310, i.e., the inner ring of the worm wheel 310 is sleeved on the worm wheel 310, and the outer ring of the worm wheel 310 is arranged on the box body 200, and the specific arrangement mode can be designed according to actual conditions. Most preferably, the conical roller bearing 400 is arranged in the annular stepped groove 311 in the middle of the worm wheel 310.

[0063] Regarding the connection relationship between the pressing member 500 and the box body 200, in some embodiments, the pressing member 500 includes a connecting portion 510 and a boss 520 arranged around the outer periphery of the connecting portion 510 and forming an abutting portion, the connecting portion 510 is screwed with the box body 200, and the boss 520 abuts against the bottom end of the inner ring of the conical roller bearing 400. This arrangement allows the relative distance between the pressing member 500 and the box body 200 to be adjusted by rotation, thereby adjusting the pre-tightening force of the conical roller bearing 400, so as to ensure the bearing transmission efficiency while avoiding a large backlash, thereby improving the compactness and overall rigidity of the heliostat slewing reducer. Of course, in other embodiments of the present scheme, the pressing member 500 can not have the above shape, and the specific shape can be designed according to actual conditions, as long as the pressing member 500 can axially press the conical roller bearing 400 along the conical roller bearing 400 and can adjust the pre-tightening force of the conical roller bearing 400.

[0064] In order to reduce the size of the heliostat slewing reducer in the axis direction of the tapered roller bearing 400, in some embodiments, the inside of the box 200 is provided with a mounting portion 211, the mounting portion 211 is provided through the center through hole of the tapered roller bearing 400, and the inner ring of the tapered roller bearing 400 is sleeved on the outer periphery of the mounting portion 211. The inside of the mounting portion 211 is provided with a threaded hole, and the outside of the connecting portion 510 is provided with a thread. The connecting portion 510 is screwed into the mounting portion 211. In the foregoing embodiments, the compression member 500 and the mounting portion 211 are connected by screwing. In other embodiments of the present application, the compression member 500 and the mounting portion 211 can be connected by a connecting member, which can be a bolt, a screw, a bolt, a rivet or other connecting structure. The connection between the compression member 500 and the mounting portion 211 is not limited here and can be designed according to the actual situation. Preferably, the compression member 500 and the mounting portion 211 are connected by screwing. In particular, in the foregoing scheme, the mounting portion 211 and the compression member 500 are two parts that can be disassembled. In some special embodiments, the mounting portion 211 and the compression member 500 can be an integral structure (in order to distinguish the foregoing compression member 500, the mounting portion 211 and the compression member 500 are referred to as a compression structure), the inner ring of the tapered roller bearing 400 is sleeved on the outer periphery of the compression structure, and the compression structure is detachably connected with the box 200. Preferably, the mounting portion 211 and the compression member 500 are two parts that can be disassembled.

[0065] Further, in order to prevent loosening between the compression member 500 and the box 200 caused by vibration during long-term operation, in some embodiments, the inner side wall of the mounting portion 211 is provided with a first recess, the outer side wall of the connecting portion 510 is provided with a second recess opposite to the opening of the first recess, the first recess and the second recess can form a locking groove, and the heliostat slewing reducer further comprises a locking pin 700, the locking pin 700 is provided through the locking groove and partially located in the first recess and partially located in the second recess, and the locking pin 700 is in interference fit with the locking groove. The locking pin 700 locks the compression member 500 and the box 200 to prevent relative rotation, thereby improving the stability of the heliostat slewing reducer.

[0066] In some embodiments, the heliostat slewing reducer further comprises a sliding bearing 600, the box 200 has an upper support portion; the worm wheel 310 has a lower support portion opposite to the upper support portion; and the sliding bearing 600 is arranged between the upper support portion and the lower support portion. The sliding bearing 600 is a thrust bearing. This arrangement can reduce the distance between the worm wheel 310 and the box 200 during the compression process of the compression member 500, thereby clamping the thrust bearing.

[0067] Specifically, the housing 200 is provided with a mounting portion 211 and an annular groove 212 on the outer periphery of the mounting portion 211. The inner ring of the tapered roller bearing 400 is fitted around the outer periphery of the mounting portion 211 and is interference-fitted with the mounting portion 211. The top of the annular groove 212 forms an upper support portion (see Appendix). Figures 2-3 As shown, the upper support portion is the top wall inside the housing 200; the worm gear 310 is annular and is fitted around the outer periphery of the mounting portion 211, with the top of the worm gear 310 forming the lower support portion (see attached diagram). Figures 2-3 As shown, the lower support part is the top surface of the worm gear 310, and the clamping part 500 can also adjust the preload on the thrust bearing.

[0068] In some embodiments, the rotation axis of the worm gear 320 is set at an angle to or parallel to the rotation axis of the housing 200. For example, the rotation axis of the worm gear 320 is perpendicular to the rotation axis of the housing 200, and the rotation axis of the housing 200 extends vertically while the rotation axis of the worm gear 320 extends horizontally, so that the housing 200 can support the mounting bracket.

[0069] Example 2

[0070] This embodiment discloses a heliostat, which adopts the heliostat rotary reducer in any of the schemes in Embodiment 1. The heliostat also includes a column 1000, a telescopic drive 90, a reflector assembly 50, a heliostat push rod support 1100, and a heliostat main beam support 1200. The rotary reducer is used to adjust the azimuth angle (i.e., orientation) of the reflector assembly 50, the telescopic drive 90 is used to adjust the pitch angle of the reflector assembly 50, and the reflector assembly 50 is used to reflect sunlight.

[0071] For details, please refer to the appendix. Figures 4 to 5 As shown, typically, one end of the column 1000 is mounted on the ground along its axial direction, and the rotary reducer is mounted on the other end of the column 1000 along its axial direction via the base 100 and fixed by a connector, which can be a screw, rivet, bolt, or other type of connector. The reflector assembly 50 includes a main beam 51 and a reflector surface, which is fixedly mounted on the main beam 51 and is used to reflect sunlight. The number of heliostat main beam supports 1200 is generally two, and they are spaced apart along the axial direction of the main beam 51 and fixed to the main beam 51. The two heliostat main beam supports 1200 are mounted on the adapter bearing 23 via a first rotating shaft (see Appendix). Figure 1As shown, the adapter shaft seat 23 is arranged on the connecting portion 220 away from the rotating portion 210, and the orientation of the heliostat is adjusted by the rotation of the slewing reducer. The number of the heliostat push rod supports 1100 is two, which are also spaced along the axial direction of the main beam 51 and fixed on the main beam 51. The telescopic driving member 90 is installed between the two heliostat push rod supports 1100 and the two first connecting plates 93. The telescopic driving member 90 can change the length by telescoping. With the telescoping action of the telescopic driving member 90, the mirror assembly 50 is further rotated around the axis of the adapter shaft seat 23, so as to realize the accurate adjustment of the angle of the mirror assembly 50.

[0072] In the present scheme, when the box body 200 rotates, the mirror assembly 50 and the telescopic driving member 90 rotate synchronously with the box body 200. Meanwhile, the telescopic driving member 90 can act independently to adjust the pitch angle of the mirror assembly 50 in another direction.

[0073] Further, the telescopic driving member 90 is a linear braking mechanism, specifically an electric push rod. The telescopic driving member 90 includes a push rod fixed end 91 and a push rod moving end 92 which are in sliding cooperation with each other. The end of the push rod fixed end 91 axially close to the push rod moving end 92 is the first end of the push rod fixed end 91, and the end of the push rod moving end 92 axially away from the push rod fixed end 91 is the second end of the push rod moving end 92. The two heliostat push rod supports 1100 are respectively provided with first hinged holes, and the first end of the push rod fixed end 91 is located between the two heliostat push rod supports 1100. The two sides of the first end of the push rod fixed end 91 are respectively provided with first hinged shafts 911, which are correspondingly arranged in the first hinged holes and rotatably arranged in the first hinged holes. The first connecting plate 93 is provided with two first connecting plates 93, which are respectively arranged on the box body 200. The two first connecting plates 93 are respectively provided with second hinged holes, and the second end of the push rod moving end 92 is located between the two first connecting plates 93. The second end of the push rod moving end 92 is provided with two second hinged shafts, which are correspondingly arranged in the second hinged holes and rotatably arranged in the second hinged holes. The arrangement of the heliostat push rod support 1100 and the first connecting plate 93 further optimizes the connection structure between the telescopic driving member 90 and the mirror assembly 50 and the box body 200, and improves the structural stability and motion stability of the heliostat.

[0074] Specifically, when the telescopic drive 90 performs the telescopic action, the push rod fixed end 91 and the push rod moving end 92 will slide relative to each other, and then the mirror assembly 50 is adjusted in angle around the adapter shaft seat 23. The introduction of the heliostat push rod support 1100 and the first connecting sheet 93 makes the connection between the telescopic drive 90 and the mirror assembly 50 and the box body 200 more stable and reliable. When the telescopic drive 90 telescopes, the push rod fixed end 91 rotates in the first hinged hole on the heliostat push rod support 1100 through the first hinged shaft 911, and the second hinged shaft of the push rod moving end 92 rotates in the second hinged hole on the first connecting sheet 93, so that the telescopic action can be smoothly and stably converted into the angle adjustment of the mirror assembly 50, and the flexibility and precision of the heliostat when tracking sunlight are improved.
