Problems solved by technology

[0002] Trough, dish, and tower solar technologies are mainly large-scale high-temperature collection technologies. Usually, solar energy is a household device, so it is relatively small. Trough, dish, and tower solar technologies cannot be directly applied to solar cookers
[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

[0064] Embodiment 1: A fixed-point array solar cooker composed of 4 solar mirrors and 3 solar cookers

[0065] as attached figure 1 , 2 , the fixed-point array solar cooker composed of 4 solar mirrors and 3 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, 2, and 3 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. 4 solar mirrors focus the solar energy on No. 1 and No. 3 solar cookers respectively, and No. 2 and No. 3 sunglasses focus on No. 2 solar storage equipment to realize the tracking and focusing of solar energy; image 3 In the afternoon, when the sun sets in the west, No. 1, 2 and 3 solar mirrors focus the solar energy on No. 2, 3 and No....

Embodiment 2

[0067] Embodiment 2: A fixed-point array solar cooker composed of 12 solar mirrors and 6 solar cookers

[0068] This example Figure 4 Shown is a fixed-point array solar cooker composed of 12 solar mirrors and 6 solar cookers. 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 3 rows and 2 columns. The solar cooker They are respectively arranged in the middle areas of the three rows of solar mirrors.

[0069] 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 sides, there are 2 solar cookers that can be selected for focusing. For No. 2, 3, 10...

Embodiment 3

[0072] Embodiment 3: 1*3 parabolic fixed-point array solar tracking solar cooker device

[0073] 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 provided with two rotating shafts, that is, the horizontal axis and the vertical axis. The horizontal axis and the vertical axis intersect perpendicularly to form a system axis, and each solar mirror is connected to a parabolic connecting part through a system axis. This embodiment consists of three system axes arranged on the connecting parts and a support connected to the ground The solar mirror bracket, the connecting parts do not move, but the three system axes move, the solar tracking control device is set to connect with each system axis, and physical and optical sensors are set on each solar mirror (2), the solar tracking control device is The integrated electronic control device composed of motor, transmi...

Abstract

The invention relates to the focusing utilization of solar energy, in particular to a solar cooker which realizes solar energy acquisition by adopting point focused solar mirrors and is applied to a fixed point array. The solar cooker comprises at least one or at least one group of point focused solar mirrors, at least one cooking appliance and tracking control devices, wherein the solar mirrors are arranged on a solar mirror support, the solar cooking appliances are arranged in solar mirror focused punctate areas and are above or below the solar mirrors, the solar mirrors change in focal length in the process of tracking solar energy, and the focal lengths of the solar mirrors are maintained to be always positioned in punctate areas of the solar cooking appliances; and the tracking control devices are used for controlling the solar mirrors to focus sunlight to at least one solar cooking appliance when the sunlight changes, and the solar cooking appliances do not move together with the solar mirrors in the process that the solar mirrors track the solar energy but maintain relative rest with the ground so as to realize the tracked focusing utilization of the solar energy.

Description

technical field [0001] The invention relates to the utilization of solar energy, in particular to the use of a point-focused solar mirror to realize solar energy collection, and the use of a point-focused converter to realize the focusing and tracking of solar cookers, and relates to the focus and utilization of solar energy. Background technique [0002] Trough, dish, and tower solar technologies are mainly large-scale high-temperature collection technologies. Generally, solar energy is a household device, so it is relatively small. Trough, dish, and tower solar technologies cannot be directly applied to solar cookers. [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...
