Description

Technical Field

[0001] The utility model belongs to the technical field of heliostats, and in particular relates to an external supporting and reinforcing device for a solar heliostat. Background Art

[0002] A solar heliostat is an optical device that reflects light from the sun or other celestial bodies to a fixed direction. It is also called a star-fixing mirror. Its function is similar to that of a coelostat, but it uses a flat mirror placed in an equatorial device and can move in the declination direction.

[0003] Publication No. CN220083350U discloses a heliostat with an anti-smashing structure, which belongs to the technical field of heliostats. The technical solution thereof includes a supporting mechanism, a heliostat and an anti-smashing buffer mechanism. The heliostat is bolted to the top of the supporting mechanism, and the anti-smashing buffer mechanism is arranged at the top of the outer side of the supporting mechanism and the top of the heliostat. By arranging the supporting mechanism, the heliostat and the anti-smashing buffer mechanism, the heliostat can be supported and positioned for use after the supporting mechanism is installed, and then an anti-smashing component is arranged at the outer side of the supporting mechanism and the top of the heliostat, so that the anti-smashing component is wrapped around the top of the outer side of the supporting mechanism and the outer side of the heliostat, and the top of the heliostat is fully protected, so as to avoid the large hail and rain generated in bad weather from hitting and impacting the surface of the heliostat, so that the heliostat at the bottom of the anti-smashing component is not easy to be damaged. However, the following problems still exist in the actual use of the patent:

[0004] The device protects the heliostat by providing an anti-smashing buffer structure. However, when the solar heliostat is in use on stormy days, strong winds will continuously blow toward the back of the heliostat when the back of the heliostat and the supporting mechanism are in use, causing the heliostat to be subjected to greater force. This requires a higher stability of the supporting mechanism when the heliostat is in use, thus making the device less practical.

[0005] Therefore, a heliostat reinforcement device is needed to solve the above problems. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] Refer to the instruction manual Figure 1 The utility model records an external support and reinforcement device for a solar heliostat, which includes a driving mechanism 1, a flow guiding mechanism 2, a first vibration reduction mechanism 3 and a second vibration reduction mechanism 4. The first vibration reduction mechanism 3 is installed on the top of the driving mechanism 1. The first vibration reduction mechanism 3 includes a first elastic component and a connecting rod component. The heliostat body is installed on the top of the first elastic component. One end of the connecting rod component is rotatably connected with the first elastic component and drives the first elastic component to compress upward or return to the initial state downward. The other end of the connecting rod component is rotatably and slidably connected with the bottom of the second vibration reduction mechanism 4. The second vibration reduction mechanism 4 has a cavity, in which a second elastic component is provided. The bottom of the second vibration reduction mechanism 4 has a through hole. The top of the first elastic component extends into the cavity. The heliostat body is placed in the cavity. The second elastic component penetrates the heliostat body and its two ends are fixed in the cavity.

The flow guiding mechanism 2 is used to guide the wind blowing toward the heliostat body to the outside along the streamlined surface. The driving mechanism 1 is used to drive the first vibration reduction mechanism 3 and the heliostat body connected to the first vibration reduction mechanism 3 and the second vibration reduction mechanism 4 to rotate as a whole. The first vibration reduction mechanism 3 is used to bear the wind load transmitted by the guide mechanism 2, so that the first elastic component is passively compressed to absorb the wind load. The second vibration reduction mechanism 4 is used to protect the heliostat body, and to assist in supporting the heliostat body through the second elastic component and provide a buffer force for the heliostat body.

[0035] Example 1

[0036] Refer to the instruction manual Figure 1-3 The driving mechanism 1 includes a support column 10, a motor 11 and a connecting plate 12. The first elastic component includes a heliostat support 32, a slider 34, a guide rod 35 and a buffer spring 36. The connecting rod assembly includes a first connecting block 30, a rotating support 31 and a second connecting block 33.

[0037] A motor 11 is installed on the top of the support column 10, and a connecting plate 12 is installed on the output shaft of the motor 11. The connecting plate 12 is used to install the first vibration reduction mechanism 3. The output shaft of the motor 11 drives the connecting plate 12 to rotate, thereby driving the first vibration reduction mechanism 3 to rotate.

[0038] One end of the guide rod 35 is fixed on the connecting plate 12, and the other end is installed with the heliostat bracket 32. The heliostat body H is installed on the top of the heliostat bracket 32. The top surface of the heliostat bracket 32 ​​is slightly smaller than the bottom surface of the heliostat body H, so that there is a certain distance between the edge of the heliostat bracket 32 ​​and the edge of the heliostat body H to install the second elastic component of the second vibration reduction mechanism 4.

[0039] The slider 34 and the buffer spring 36 are both sleeved on the guide rod 35. One end face of the slider 34 is opposite to the connecting plate 12, and the other end face is fixedly installed with one end of the buffer spring 36. The other end of the buffer spring 36 is fixedly installed with the bottom of the heliostat bracket 32. A plurality of second connecting blocks 33 are installed on the periphery of the slider 34. One end of each rotating bracket 31 is rotatably connected to the corresponding second connecting block 33 through a pin shaft, and the other end is rotatably connected to the corresponding first connecting block 30 through a pin shaft. The bottom of the second damping mechanism 4 has a plurality of slide grooves, and each slide groove is slidably connected to a first connecting block 30.

[0040] Instructions attached Figure 3 For example, the slider 34 of the present embodiment is a rectangular structure, the number of the rotating bracket 31 and the second connecting block 33 are both 4, the number of the first connecting blocks 30 is 8, the four second connecting blocks 33 are respectively installed on the four outer wall surfaces of the slider 34, the bottom of the second vibration damping mechanism 4 is rectangular, and each two first connecting blocks 30 are installed in a group on one side of the bottom of the second vibration damping mechanism 4, the rotating bracket 31 is a trapezoidal structure, the small end of the trapezoidal structure is rotatably connected to the second connecting block 33 by a pin shaft, and the large end of the trapezoidal structure is rotatably connected to the two first connecting blocks 30 by a pin shaft.

[0041] With the structure of this embodiment, when the rotating bracket 31 is subjected to wind load, the slider 34 is pushed to slide upward along the guide rod 35 and compress the buffer spring 36. The displacement of the slider 34 simultaneously pushes the first connecting block 30 installed at one end of the rotating bracket 31 in the opposite direction to slide outward along the bottom slide groove of the second vibration reduction mechanism 4. The buffer spring 36 is compressed for buffering, which not only reduces the influence of strong wind on the heliostat body H, but also reduces the force on the output shaft of the motor 11, thereby increasing the service life of the heliostat body H and the motor 11, and at the same time improves the structural strength of the external support and reinforcement device, making the external support and reinforcement device more practical.

[0042] Example 2

[0043] Refer to the instruction manual Figure 4On the basis of Example 1, the flow guide mechanism 2 includes a support rod 20 and an arc plate 21. One end of the support rod 20 is connected to the bottom of the rotating bracket 31, and the other end is connected to the inner arc surface of the arc plate 21, and the bottom profile matches the inner arc surface of the arc plate 21. The matching profile of the arc plate 21 and the support rod 20 is a trapezoidal structure, and the small end of the trapezoidal structure is close to the first connecting block 30, and the large end is close to the second connecting block 33. And the overall height of the support rod 20 gradually decreases from the end close to the first connecting block 30 to the end close to the second connecting block 33.

[0044] In this embodiment, there are four flow guide mechanisms 2, which are respectively mounted on four rotating brackets 31. The four flow guide mechanisms 2 are arranged in an umbrella-shaped structure, wherein the cone angle end of the umbrella-shaped structure surrounds the outside of the motor 11, and the end opposite to the cone angle of the umbrella-shaped structure surrounds the outside of the first connecting block 30.

[0045] With the structure of this embodiment, when strong wind blows toward the guide mechanism 2, the wind is guided to the outside along the outer arc surface of the guide mechanism 2 close to the side edge of the first connecting block 30 through the arc plate 21, which effectively reduces the wind load and reduces the pressure of the support rod 20, thereby achieving the effect of enhancing the supporting force, protecting the overall structure of the first vibration reduction mechanism 3 and the second vibration reduction mechanism 4, and further protecting the heliostat body H located in the second vibration reduction mechanism 4 from the influence of the wind load, thereby improving the overall structural strength and high stability.

[0046] Example 3

[0047] Refer to the instruction manual Figure 1 , 5 This embodiment includes all the structures of the embodiment 1, and the second vibration reduction mechanism 4 further includes a guard plate 40, a guard frame 43 and a bottom plate 44. The second elastic component includes a positioning column 41 and a positioning spring 42.

[0048] The guard plate 40 and the bottom plate 44 are arranged at intervals, and the guard plate 40 and the bottom plate 44 are rectangular plates. The guard frame 43 is mounted around the guard plate 40 and the bottom plate 44, and forms an internal cavity with the guard plate 40 and the bottom plate 44. The bottom of the bottom plate 44 has a mounting hole for passing the guide rod 35 and the buffer spring 36, so that the buffer spring 36 can move freely when it is compressed or restored to an initial state.

[0049] There are multiple positioning posts 41, each of which penetrates the inner side of the edge of the heliostat body H. A through hole for the positioning post 41 is provided on the inner side of the edge of the heliostat body H, and the through hole is gap-matched with the heliostat post 41. The top of the positioning post 41 is fixed on the guard plate 40, and the bottom is fixed on the bottom plate 44. Each positioning spring 42 is sleeved on one positioning post 41. In the natural state, one end of the positioning spring 42 is fixed to the bottom surface of the heliostat body H, and the other end is fixed to the bottom plate 44. A slide groove is provided at the bottom of the bottom plate 44, and the first connecting block 30 slides along the slide groove.

[0050] In this embodiment, two positioning posts 41 are respectively provided on the inner sides of the four edges of the heliostat body H.

[0051] With the structure of this embodiment, the heliostat body H is located in a cavity formed by the guard plate 40, the guard frame 43 and the bottom plate 44, which can protect the front and back of the heliostat body H at the same time, meet the requirements of the heliostat being applied to more harsh environments, and improve the practical life of the heliostat. When the device is subjected to wind load, the buffer spring 36 can buffer the heliostat.

[0052] The working principle of the external support and reinforcement device for solar heliostat of the utility model is as follows: when the solar heliostat is used, the rotation is controlled by the motor 11 to realize the control of the first vibration reduction mechanism 3, the heliostat body and the second vibration reduction mechanism 4 to rotate as a whole. When strong winds occur, the wind blows the arc plate 21, so that the arc plate 21 pushes the rotating bracket 31 and the second connecting block 33 to rotate through the support rod 20, and pushes the first connecting block 30 to slide in the slide groove of the bottom plate 44, and the slider 34 moves along the guide rod 35 in the direction of the principle motor 11 to compress the buffer spring 36, and the heliostat body compresses the positioning spring 42 based on the wind load direction, and the wind flows along the two sides of the arc plate 21, and the heliostat body is protected by the guard plate 40, the guard frame 43 and the bottom plate 44.

[0053] Compared with the prior art, the utility model reduces the thrust of strong wind on the heliostat and reduces the pressure of the guide rod 35 by arranging the arc plate 20, the rotating bracket 31, the slider 34, the buffer spring 36 and the positioning spring 42, so that the stability of the solar heliostat is stronger. By arranging the guard plate 40, the guard frame 43 and the bottom plate 44, it is convenient to protect the front and back of the solar heliostat, and the service life of the solar heliostat is improved, so that the practicality of the solar heliostat is stronger.

[0054] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present application is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the present application. Any figure mark in the claims should not be regarded as limiting the claims involved.
