Abstract
Description
Technical Field
[0001] This utility model relates to the field of solar energy application technology, specifically to an extreme weather heliostat protection device. Background Technology
[0002] A heliostat is a plane mirror device that projects sunlight in a directional manner. It belongs to the field of solar energy application technology. Secondly, a heliostat is an optical device that reflects the light of the sun or other celestial bodies in a fixed direction. It is also called a star-fixing mirror. Its function is similar to that of a celestial fixation mirror, but it uses a plane mirror placed in an equatorial device and can be moved in the direction of declination.
[0003] When heliostats are in outdoor operation, they may be affected by extreme weather such as hail. When extreme weather occurs, it is impossible to manually protect the heliostat mirror with a large area of protective cloth. Even if the protective cloth is laid close to the mirror, the force of hail can still damage the mirror. In addition, it will also increase the labor cost. Therefore, we have proposed an extreme weather heliostat protection device to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of existing methods that, when subjected to extreme weather such as hail, cannot be protected by manually laying large-area protective cloths to protect the heliostat mirrors during extreme weather events. Even if the protective cloths are laid close to the mirrors, the force of hail can still damage the mirrors, and this also increases the labor costs.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An extreme weather heliostat protection device includes a heliostat body, a support column fixedly connected to the bottom end of the heliostat body, a connecting flange fixedly connected to the bottom end of the support column, a protective mechanism provided on the surface of the heliostat body, and track grooves fixedly connected to both sides of the rear end of the heliostat body, the track grooves being semi-circular, and a control mechanism provided on the opposite side of the track grooves, the control mechanism being movably connected to the protective mechanism.
[0007] Furthermore, the protective mechanism includes a rotating roller, a protective cloth, a connecting strip, a folding frame, a connecting block, and a servo motor. One end of the protective cloth is wrapped around the surface of the rotating roller, and the connecting strip is fixedly connected to the end of the protective cloth away from the rotating roller. The connecting block is rotatably connected to both ends of the rotating roller, and both ends of the folding frame are movably connected to the bottom sides of both ends of the connecting strip and the inner side of the connecting block through rotating shafts, respectively. The output end of the servo motor is fixedly connected to one end of the rotating roller through a coupling.
[0008] Furthermore, the bottom of the connecting block and the servo motor are located on the outside of the track groove, and the rotating roller is slidably connected to the track groove.
[0009] Furthermore, the protective mechanism also includes a connecting block and a return spring. One end of the connecting block is wound around both ends of the rotating roller, and the other end of the connecting block passes through the connecting strip and is fixedly connected to the inner side of the connecting strip. A return spring is sleeved on the outer side of the connecting block, and the return spring is located on the opposite side of the connecting strip and the connecting block.
[0010] Furthermore, the control mechanism includes an electro-hydraulic rod, a control rod, and a drive bar. The top end of the electro-hydraulic rod is movably connected to the middle position of the control rod via a collar. The drive bar is arc-shaped and is rotatably connected to both ends of the control rod.
[0011] Furthermore, the end of the electro-hydraulic rod away from the control rod is fixedly connected to the top of the support column. The control rod and the drive bar are both located on opposite sides of the track groove. The top of the drive bar is movably connected to the outside of the rotating roller through a collar.
[0012] Compared with existing technologies, this extreme weather heliostat protection device has the following advantages:
[0013] I. This utility model uses a protective mechanism with a servo motor to rotate and slowly loosen the pull rope. At this time, the return spring and the folding frame react to the connecting bar, causing it to move forward. This loosens the rotating roller, pushes the protective cloth, and covers the surface of the heliostat body. This is beneficial for quickly protecting the heliostat mirror surface in extreme weather conditions, preventing damage to the mirror surface and serious impact on its working efficiency.
[0014] Second, this utility model uses a control mechanism to extend the electric hydraulic rod so that its output end moves forward to push the control rod. At this time, the drive bar is driven by the control rod to push the rotating roller upward and move it along the track groove until the rotating roller is parallel to the surface of the heliostat body. This helps to avoid blocking the angle of sunlight when the heliostat body is working normally.
[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1-4 As shown, this utility model provides the following technical solution:
[0023] The extreme weather heliostat protection device includes a heliostat body 1, a support column 2 fixedly connected to the bottom end of the heliostat body 1, a connecting flange 3 fixedly connected to the bottom end of the support column 2, a protective mechanism 4 provided on the surface of the heliostat body 1, and track grooves 5 fixedly connected to both sides of the rear end of the heliostat body 1, the track grooves 5 being semi-circular, a control mechanism 6 provided on the opposite side of the track grooves 5, and the control mechanism 6 being movably connected to the protective mechanism 4.
[0024] like Figure 2 , Figure 3 and Figure 4As shown, the protective mechanism 4 includes a rotating roller 401, a protective cloth 402, a connecting strip 403, a folding frame 404, a connecting block 405, and a servo motor 406. One end of the protective cloth 402 is wrapped around the surface of the rotating roller 401, and the connecting strip 403 is fixedly connected to the end of the protective cloth 402 away from the rotating roller 401. The connecting block 405 is rotatably connected to both ends of the rotating roller 401, and both ends of the folding frame 404 are movably connected to the bottom sides of both ends of the connecting strip 403 and the inner side of the connecting block 405 respectively through rotating shafts. The output end of the servo motor 406 is fixed through a coupling. The bottom of the connecting block 405 and the servo motor 406 are connected to one end of the rotating roller 401 and located on the outside of the track groove 5. The rotating roller 401 and the track groove 5 are slidably connected. The protective mechanism 4 also includes a pull rope 407 and a return spring 408. One end of the pull rope 407 is wrapped around both ends of the rotating roller 401. The other end of the pull rope 407 passes through the connecting strip 403 and is fixedly connected to the inside of the connecting strip 403. The outside of the pull rope 407 is fitted with a return spring 408, and the return spring 408 is located on the opposite side of the connecting strip 403 and the connecting block 405.
[0025] The servo motor 406 rotates, and the pull rope 407 is slowly released. At this time, the return spring 408 and the folding frame 404 both react to the connecting bar 403, causing it to move forward. This releases the rotating roller 401, pushes the protective cloth 402, and covers the surface of the heliostat body 1. This is beneficial for quickly protecting the heliostat mirror surface in extreme weather conditions, preventing damage to the mirror surface and serious impact on its working efficiency.
[0026] like Figure 2 and Figure 3 As shown, the control mechanism 6 includes an electro-hydraulic rod 601, a control rod 602, and a drive bar 603. The top end of the electro-hydraulic rod 601 is movably connected to the middle position of the control rod 602 via a collar. The drive bar 603 is arc-shaped and is rotatably connected to both ends of the control rod 602. The end of the electro-hydraulic rod 601 away from the control rod 602 is fixedly connected to the top end of the support column 2. The control rod 602 and the drive bar 603 are both located on opposite sides of the track groove 5. The top ends of the drive bars 603 are movably connected to the outer side of the rotating roller 401 via collars.
[0027] The control electric hydraulic rod 601 extends so that its output end pushes the control rod 602 forward. At this time, the drive bar 603 is driven by the control rod 602 to push the rotating roller 401 upward and move it along the track groove 5 until the rotating roller 401 is parallel to the surface of the heliostat body 1. This helps to avoid blocking the angle of sunlight when the heliostat body 1 is working normally.
[0028] The working principle is as follows:
[0029] During use, in the event of extreme weather such as hail, the electric hydraulic rod 601 extends, causing its output end to push the control rod 602 forward. At this time, the drive bar 603 is driven by the control rod 602 to push the rotating roller 401 upward, moving it along the track groove 5 until the rotating roller 401 is parallel to the surface of the heliostat body 1. This helps to prevent the heliostat body 1 from blocking the angle of sunlight during normal operation. Subsequently, the servo motor 406 is controlled to rotate, and the pull rope 407 is slowly released. At this time, the return spring 408 and the folding frame 404 both react on the connecting bar 403, causing it to move forward. This releases the rotating roller 401, pushes the protective cloth 402, and covers the surface of the heliostat body 1. This helps to quickly protect the heliostat mirror surface in the event of extreme weather, preventing damage to the mirror surface and serious impact on its working efficiency.
