The shade area of the sunshade assembly 102 can be adjusted.

The sunshade assembly 102 includes a skeleton including an inner ring 103 and at least two slide rails 104. One end of the slide rail 104 is disposed on the circumference of the inner ring 103. The sliding member 105 is disposed on the slide rail 104. The cloth, the shade cloth is connected to the sliding member 105; the inner ring 103 is connected to the concentrating disc 101, and the other end of the slide rail 104 is connected to the concentrating disc 101. By providing the sunshade assembly 102 on the side where the concentrating disc 101 receives sunlight, the shading assembly 102 can quickly adjust the shading area, or can be said to adjust the concentrating area of the concentrating disc 101 to satisfy the heat absorbing equipment, the engine, and the heat absorbing equipment and the engine. The focusing energy required by the overheat protection device improves work efficiency.

The concentrating disc 101 is coupled to the sunshade assembly 102, and the inner ring 103 of the sunshade assembly 102 is fixed to the concentrating disc 101 by a detachable fastening device, and the other end of the sliding rail 104 is fixed to the concentrating disc 101 by a detachable fastening device. edge. In view of the fact that the sunshade assembly 102 constitutes a circular structure, the number of the slide rails 104 is preferably three, and the circumferences of the adjacent slide rails 104 and the inner rings 103 constitute a sector structure. The shade cloth can be moved on the slide rail 104 by the sliding member 105 without falling off the slide rail 104. The shade cloth is moved from the position near the inner ring 103 to the other end of the slide rail 104. At this time, the sector structure covered by the shade cloth is a sunshade portion, and the sector structure not covered by the shade cloth is a light transmitting portion.

The shading area is adjusted by adjusting the coverage area of the sunshade on the skeleton, or it can be said that the concentrating area of the concentrating disc is adjusted. Among them, there are various ways to adjust the shading area. It may be manually adjusted by sliding the sliding member to move on the sliding rail, or by other means.

The sunshade device further includes a pulley 106 mounted at both ends of the slide rail, and the pulley 106 is provided with a traction member 107 such that the traction member 107 pulls the shade cloth to move on the slide rail. The traction member 107 can be driven by a hand or a tractor. For example, a person applies a force to the traction member 107 to pull the shade cloth to move on the slide rail 104. In the present embodiment, the sunshade device further includes a tractor 108 that is disposed on the inner ring 103 and coupled to the traction member 107. By controlling the forward and reverse rotation of the tractor 108 by the control system, the traction shade is moved along the inside and outside of the slide rail 104, and all the shade cloths can be simultaneously guided along the slide rails. 104 moves. The sunshade opening and covering of the plurality of sunshade portions can be performed simultaneously or separately. In this embodiment, the traction member 107 is a traction rope, and the sliding member 105 is a wire loop.

The slide rails 104 are evenly distributed on the circumference of the inner ring 103. As shown in FIG. 3, the number of the slide rails 104 is 12, a fan-shaped structure is formed between adjacent slide rails 104, a fan-shaped structure having a shade cloth is a sunshade portion 201, and a fan-shaped structure without a shade cloth is a light-transmitting portion 202. The light transmitting portion 202 is a condensing area of the concentrating disc. The sunshade portion 201 is spaced apart from the light transmitting portion 202. As shown in FIG. 4, all of the sector structures are the shade portions 201, which are all in a state of shielding the condensed disc. By adjusting the distribution of the sunshade portion 201, the focusing energy required for the heat absorbing device, the engine, and the heat absorbing device and the engine's overheat protection device is satisfied.

As shown in FIG. 5, the skeleton is a skeleton having a plurality of preset numbers of concentric rings 203 having a radius larger than the radius of the inner ring 103. A plurality of concentric rings 203 in the skeleton are uniformly distributed, and the shade cloth can cover an area formed by any one of the concentric rings 203 and the inner ring 103. As shown in FIG. 6, the sunshade portions having different radii are formed.

The sunshade area can be easily and quickly adjusted by the sunshade assembly, or it can be said that the concentrating area of the concentrating disk is adjusted to meet the focusing energy required for the heat absorbing equipment, the engine, and the heat absorbing equipment and the engine overheat protection device. For example, when the engine is commissioned, it is convenient to open or cover part of the concentrating disc. When the engine is overheated, it can quickly cover part of the concentrating disc. When the engine needs part of the light, cover a certain part of the concentrating disc as needed. In addition, when a certain reflective lens on the concentrating disc needs to be adjusted, the sunshade assembly can block other reflective lenses that do not need to be adjusted, that is, by adjusting the shading area and the orientation, preventing the reflecting lens that does not need focusing to form a large area. Spot, which affects the judgment of the focus position of the condenser. Therefore, providing a sunshade assembly on the surface of the concentrating disk to receive sunlight is advantageous for focus adjustment of the condensing mirror. The concentrating disc sunshade device provided by the invention can realize the focusing of the concentrating disc and the protection of the engine faster and better, and improve the work efficiency.

The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments are obvious to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention will not be limited to the one shown herein These embodiments are to be accorded the broadest scope consistent with the principles and novel features disclosed herein.
