Problems solved by technology

[0003] The tower system is a solar cooker that uses a solar mirror as a heliostat and focuses multiple solar reflectors on a solar cooker. Due to the characteristics of tower solar energy collection, the utilization time of part of the solar mirror in tracking the solar process is only For example, the solar mirror on the east side of the tower is basically unusable in the morning, and can only be used after noon or afternoon, so the efficiency of solar energy collection is low. This technical solution can achieve high temperature collection, but usually its scale is relatively small. Large, not suitable for small or home systems
[0004] Existing solar cookers are mainly home-type dish systems, which have poor automatic tracking capabilities and poor solar energy collection efficiency, so they cannot be promoted and applied on a large scale

Embodiment 1

[0071] Embodiment 1: A mobile point array solar energy collection and utilization system composed of 4 solar mirrors and 2 solar energy utilization devices

[0072] as attached figure 1 , 2 , the mobile point array solar collection and utilization system composed of 4 solar mirrors and 2 solar cookers shown in 3, figure 1 , 2 , 3 are the collection and utilization of solar energy in the morning, noon and afternoon respectively, figure 1 In the morning, when the sun rises from the east, No. 1, 2 and 3 solar mirrors focus the solar energy on No. 1 and No. 2 solar cookers respectively, realizing the tracking and focusing of solar energy; figure 2 At noon, the sun is located in the central area of ​​the sky, No. 1 and No. 2 solar mirrors respectively focus the solar energy on No. 1 solar cooker, and No. 3 and No. 4 solar mirrors focus on No. 2 solar storage equipment to realize the tracking and focusing of solar energy; image 3 In the afternoon, the sun falls in the west, 1 ...

Embodiment 2

[0073] Embodiment 2: A moving point array solar energy collection and utilization system composed of 12 solar mirrors and 6 solar energy utilization devices

[0074] This example Figure 4 The mobile point array solar collection and utilization system composed of 12 solar mirrors and 6 solar cookers is shown. The 12 solar mirrors are arranged in an array of three rows and four columns, and the 6 solar cookers are arranged in an array of three rows and two columns. The solar cookers are respectively arranged in the middle area of ​​the three rows of solar mirrors.

[0075]In different time periods of morning, noon, and afternoon, solar mirrors 1-12 can choose different solar cookers from 1-6 to focus, and according to the actual solar energy collection efficiency, select different focus points to focus, and are in different positions Solar mirrors No. 1-12, the selection of solar cookers that can be focused is also different. For solar mirrors No. 1, 5, 9, 4, 8, and 12 on both...

Embodiment 3

[0078] Embodiment 3: 1*3 moving point solar energy tracking utilization system

[0079] as attached Figure 5 As shown, this embodiment adopts three parabolic dish solar mirrors (2), which are arranged on a parabolic connecting part, and each solar mirror is connected to the parabolic connecting part through a system axis, and the horizontal axis of the system axis The axis and the longitudinal axis are perpendicular to each other. This embodiment is a solar mirror bracket composed of three system axes arranged on the connecting parts. The connecting parts do not move, but the three system axes move. connection, set physical and optical sensors on each solar mirror (2), the solar tracking control device is an integrated electronic control device composed of motor, transmission gear and electronic control part, and adopts a tracking system that complements physical and optical tracking to realize tracking Solar energy tracking, at the same time, the solar cooker is equipped wi...

Abstract

The invention relates to solar energy utilization, in particular to solar energy collection by using a point focusing solar mirror and application of the point focusing solar mirror to a moving point array solar cooker. The moving point array solar cooker at least comprises one or one group of point focusing solar mirrors, at least one solar cooker and a tracking control device for control, wherein the solar mirrors are arranged on a solar mirror support; solar cookers are arranged on a solar cooker support, and are arranged in a punctiform area focused by the solar mirrors and above or below the solar mirrors; and the tracking control device controls the solar mirrors to focus sunlight to at least one solar cooker when the sunlight changes, the solar cookers move in the process that the solar mirrors track solar energy, and each or each group of solar mirrors select the solar cooker capable of reaching the highest solar energy utilization efficiency for focusing, so that the solar energy is tracked, focused and utilized.

Description

technical field [0001] The invention relates to the utilization of solar energy, in particular to the use of point-focused solar mirrors to realize solar energy collection, the use of solar point focus to realize the focusing and tracking of solar cookers, and the focus and utilization of solar energy. Background technique [0002] There are mainly two types of solar point focusing utilization technologies: tower type and butterfly type. The dish type system uses solar mirrors to focus on a solar energy utilization device. And the solar energy utilization equipment of existing dish technology is to move with the change of sunglasses, because the weight of large solar energy utilization equipment will increase load, is unfavorable for tracking, thereby existing dish technology needs improvement. [0003] The tower system is a solar cooker that uses a solar mirror as a heliostat and focuses multiple solar reflectors on a solar cooker. Due to the characteristics of tower solar ...
