Description

Technical Field

[0001] This utility model belongs to the field of beam reversal and extension technology, and particularly relates to a two-dimensional beam free reversal device. Background Technology

[0002] Beam redirection technology has wide applications in daily life. In the field of photovoltaic power generation, various technologies are needed to efficiently utilize sunlight in order to improve power generation efficiency and output. In the field of agricultural technology, taking greenhouse cultivation as an example, when natural light is insufficient, artificial light sources are needed to supplement the light to meet the needs of plant photosynthesis and help plants grow vigorously.

[0003] Patent (application number: 202023063329.2) discloses a device for freely transforming a light beam. The protective tube and support frame of this patent form a parallelogram, and the direction of the reflected light beam is changed by adjusting the contraction of the parallelogram. This patent only supports angle adjustment in a single plane (such as the horizontal direction), which limits its flexibility and is also limited by the weak load capacity of the main rotating shaft.

[0004] Based on the above-mentioned needs and technical problems, this application provides a two-dimensional beam free direction-changing device. Utility Model Content

[0005] This invention provides a two-dimensional beam free-direction device to solve the technical problems of only one-dimensional direction change and low load capacity in the prior art.

[0006] This utility model provides a two-dimensional beam free-direction device, characterized in that it includes: a reflector, a coaxial gear set, an incident protection tube, and an exit protection tube. The coaxial gear set is fixedly connected to the reflector, the incident protection tube, and the exit protection tube, respectively. The reflector is disposed on the axis of the coaxial gear set and is perpendicular to the centerline of the incident protection tube and the exit protection tube. The incident protection tube and the exit protection tube are disposed on the same side of the reflector. The incident protection tube and the exit protection tube are symmetrically arranged based on the centerline. When the coaxial gear set rotates, the incident protection tube and the exit protection tube move symmetrically with the same amplitude based on the centerline.

[0007] In one embodiment, the two-dimensional beam free-direction device further includes an extension protection tube, and the emission protection tube is rotatably connected to the extension protection tube.

[0008] In one embodiment, the ejector protection tube is provided with a rotating connection device, which is fixedly connected to both the ejector protection tube and the extension protection tube; the rotating connection device enables the extension protection tube and the ejector protection tube to rotate coaxially.

[0009] In one embodiment, the rotating connection device is a sliding bearing.

[0010] In one embodiment, the coaxial gear set is a set of coaxial gears that move symmetrically and with the same amplitude based on a reference wheel, where the reference wheel is a specific gear in the coaxial gear set that serves as a reference standard.

[0011] In one embodiment, the reference wheel is fixedly connected to the reflector; the coaxial gears moving with the same amplitude are fixedly connected to the incident protection tube and the exit protection tube, respectively.

[0012] In one embodiment, the reflector is positioned perpendicular to the centerline; the centerline coincides with the normal to the light rays passing through the incident and exit protection tubes.

[0013] The beneficial effects of this utility model embodiment compared with the prior art are:

[0014] 1. Two-dimensional free direction change of the output beam is achieved through a reflector, coaxial gear set, incident protection tube and exit protection tube. Not only can the angle of the incident protection tube and exit protection tube be freely adjusted, but there is no reflection and refraction of the beam in the device except for the reflector, which reduces the loss of energy carried by the beam.

[0015] 2. This application replaces the support frame in the prior art with a coaxial gear set. The symmetrical linkage of the incident / exit protection tubes is achieved through the gear meshing between the components in the coaxial gear set, which enables the application to achieve precise angle adjustment and better stability.

[0016] 3. This application improves the overall load capacity of the two-dimensional beam free direction changing device by meshing multiple components in the coaxial gear set, overcoming the technical problem of weak load capacity in the prior art.

It provides a new method for the scientific utilization of sunlight and other occasions. Compared with the existing technology, it has a substantial improvement, a breakthrough, and great application value. It breaks through the application limitations of large-scale sunlight utilization equipment such as sunlight furnaces and can promote the development of technologies such as sunlight lighting, various extended utilizations of sunlight, and medium and high temperature utilization of solar energy.

[0023] To enable those skilled in the art to better understand this solution, the technical solutions in the embodiments of this solution will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this solution, not all of them. Based on the embodiments of this solution, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this solution.

[0024] The term "comprising" and any other variations thereof in the specification, claims, and accompanying drawings of this invention mean "including but not limited to," and are intended to cover a non-exclusive inclusion, not limited to the examples listed herein. Furthermore, the terms "first" and "second," etc., are used to distinguish different objects, not to describe a specific order.

[0025] The implementation of this utility model will be described in detail below with reference to the specific accompanying drawings:

[0026] Figure 1 A schematic diagram of a two-dimensional beam free-direction device provided by this utility model is shown. For ease of explanation, only the parts related to the embodiments of this utility model are shown, and are described in detail below:

[0027] like Figure 1 As shown in the figure, the two-dimensional beam free-direction device provided in this embodiment of the present invention includes: a reflector 1, a coaxial gear set 2, an incident protection tube 3, and an exit protection tube 4. The coaxial gear set 2 is fixedly connected to the reflector 1, the incident protection tube 3, and the exit protection tube 4, respectively.

[0028] In one possible implementation, the reflector 1 is positioned on the axis of rotation of the coaxial gear set 2 and perpendicular to the centerline 100 of the incident protection tube 3 and the exit protection tube 4. Explanatoryly, the axis is the centerline of the rotational axis of the coaxial gear set 2.

[0029] In one possible implementation, the incident protection tube 3 and the exit protection tube 4 are located on the same side of the reflector 1.

[0030] In one possible implementation, the incident protection tube 3 and the exit protection tube 4 are symmetrically arranged based on the centerline 100. When the coaxial gear set 2 moves, the incident protection tube 3 and the exit protection tube 4 can move symmetrically with the same amplitude based on the centerline 100.

[0031] In one possible implementation, a two-dimensional beam free-direction device further includes an extension protection tube 5, which is rotatably connected to the exit protection tube 4.

[0032] In one possible implementation, the ejector protection tube 4 is provided with a rotating connecting device 6, which is fixedly connected to both the ejector protection tube 4 and the extension protection tube 5. The rotating connecting device 6 enables the extension protection tube 5 to rotate coaxially with the ejector protection tube 4.

[0033] Optionally, the rotating connection device 6 can be a bearing.

[0034] Preferably, the rotating connection device 6 can be a sliding bearing.

[0035] In real-world scenarios, refer to Figure 1 As shown, when the extension protection tube 5 is fixed as the light output end, the incident protection tube 3 makes a pitching motion, and the exit protection tube 4 rotates coaxially with respect to the extension protection tube 5, the incident light can always be emitted from the extension protection tube 5.

[0036] This application provides a two-dimensional beam free-direction device that combines the change of the angle between the incident protection tube 3 and the reflection protection tube 4 with the movement of the reflector 1 to fit the principle of light reflection. The two-dimensional direction change of the light can be achieved by rotating the connecting device 6.

[0037] Figure 2 This invention provides a schematic diagram of the internal structure of a coaxial gear set. The following references... Figure 2 A detailed description of the coaxial gear set is provided.

[0038] Preferably, the coaxial gear set 2 can be a planetary gear system. Explaining this, a planetary gear system is a typical coaxial gear set, its core structure consisting of a central gear (sun gear) and one or more external gears (planet gears) rotating around it. This structure is highly similar to the pattern of planets revolving around the sun, hence the name. From a structural perspective, the planetary gear system is analogous to a microscopic solar system: the central sun gear is like the sun, and the multiple planet gears are like planets. These planet gears not only "rotate" around their own axes but also "revolve" around the axis of the sun gear, driven by the planet carrier.

[0039] Optionally, the coaxial gear set 2 may include a sun gear 21, a ring gear 22, a gear carrier 23, and a plurality of planet gears 24. Each of the plurality of planet gears 24 is connected to the gear carrier 23 via a pin, and each planet gear 24 meshes with the sun gear 21 and the ring gear 22 respectively.

[0040] In one possible implementation, the sun gear 21 is fixedly connected to the reflector 1, the gear carrier 23 is fixedly connected to the incident protection tube 3, and the gear ring 22 is fixedly connected to the exit protection tube 4.

[0041] In one possible implementation, the sun gear 21 is fixedly connected to the reflector 1, the gear carrier 23 is fixedly connected to the exit protection tube 4, and the gear ring 22 is fixedly connected to the entrance protection tube 3.

[0042] Preferably, the rotation ratio of the sun gear 21 to the gear carrier 23 is 2:1.

[0043] In one possible implementation, the reflector 1 is positioned perpendicular to the center line 100, while the center line 100 coincides with the normal of the light rays passing through the incident protection tube 3 and the exit protection tube 4.

[0044] The two-dimensional beam free-direction device provided in this application uses the motion synthesis and fitting principle of light reflection of the coaxial gear set 2, combined with the rotation connection device, to freely change the direction and position of the output beam, so that the light can freely change the direction in both azimuth and pitch.

[0045] To facilitate understanding of this utility model Figure 3 This is a schematic diagram of the principle of free beam reversal provided by this utility model. The following is in conjunction with... Figure 3 The device for freely changing the direction of a two-dimensional beam is further explained.

[0046] In one embodiment, the incident beam 200 enters the incident protection tube 3, is reflected by the reflector 1, and then passes through the exit protection tube 4 and the extension protection tube 5 to form the exit beam 400.

[0047] In a real-world scenario, when the direction or angle of the incident beam 200 changes between the incident protection tube 3, the exit protection tube 4, and the extension protection tube 5, the incident beam 200 can smoothly pass through the incident protection tube 3 and, after being reflected by the reflector 1, exit the exit protection tube 4 and the extension protection tube 5 to emit the exit beam 400, thus achieving two-dimensional free direction change of the beam.

[0048] This invention provides a two-dimensional beam free-direction device, which creatively utilizes the motion synthesis function of coaxial gears to achieve the principle of light reflection by synthesizing the angle change between the incident and exiting protective tubes with the motion of the reflector. That is, the mechanical motion of the incident and exiting protective tubes and the reflector always conforms to the optical reflection principle of the relationship between the incident angle, the reflection angle and the normal. In use, the light can be understood as a parallel beam within the range of the protective tube. The beam passes through this device, is reflected by the reflector and freely changes direction with the protective tube. The reflector is fixedly connected to the sun gear and is set perpendicular to the center line of the incident and exiting protective tubes. The incident and reflecting protective tubes are fixedly connected to the gear carrier and gear ring of the planetary gear device, respectively. The angle change of the reflector is set to half of the angle change of the protective tube. The beam enters from one end of the incident protective tube and exits from the exiting protective tube at the end of the device, realizing that the incident light to the exit light is always completed within this device, and there is no reflection or refraction except for the reflector.

[0049] The beneficial effects of this utility model embodiment compared with the prior art include, but are not limited to:

[0050] 1. Two-dimensional free direction change of the light beam is achieved through a reflector, a coaxial gear set, an incident protection tube, and an exit protection tube. Not only can the angles of the incident protection tube and the exit protection tube be freely adjusted, but there is no reflection or refraction of the light beam in the device except for the reflector, which reduces the loss of energy carried by the light beam.

[0051] 2. This application replaces the support frame in the prior art with a coaxial gear set. The symmetrical linkage of the incident / exit protection tube is realized through the gear meshing between the components in the coaxial gear set, which enables the application to achieve precise angle adjustment and better stability after adjustment.

[0052] 3. This application improves the overall load capacity of the two-dimensional beam free direction changing device by meshing multiple components in the coaxial gear set, overcoming the technical problem of weak load capacity in the prior art.

[0053] The two-dimensional beam free-direction device claimed in this application has a scientific and reasonable structure and is safe and convenient to use. It provides a new method for the scientific utilization of sunlight and other occasions. Compared with the existing technology, it has a substantial improvement, a breakthrough, and great application value. It breaks through the application limitations of sunlight utilization equipment such as sunlight furnaces and can promote the development of technologies such as sunlight lighting, various extended utilizations of sunlight, and medium and high temperature utilization of solar energy.

[0054] This application can also be widely used in various extended uses of sunlight, such as new agriculture, photothermal conversion, medium heating, photovoltaics, etc. In terms of lighting alone, it can break the traditional limitations of sunlight orientation, and is not restricted by the orientation of the room (space) or even above or below ground, comprehensively improving the lighting level of similar places, improving the flexibility and safety of sunlight utilization, and enhancing the efficiency of sunlight utilization.

[0055] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
