Description

Technical Field

[0001] This invention relates to the field of photothermal hydrogen production equipment technology, and in particular to a multimodal disk and its photothermal hydrogen production equipment. Background Technology

[0002] Solar thermal hydrogen production equipment is an energy conversion device that uses solar energy as the main energy source, converts light energy into heat energy, and further drives water decomposition reaction to produce hydrogen. Its basic principle is to concentrate solar radiation through a concentrating system and apply it to the reaction device (such as a thermochemical reactor or a high-temperature electrolyzer), converting low-density solar energy into high-temperature heat energy, so that the water in the reaction device decomposes under high temperature or electro-thermal coupling conditions to produce hydrogen and oxygen.

[0003] Although current solar thermal hydrogen production equipment can track the sun around the clock, its concentrating system lacks adjustability. This makes it difficult for the light reflected from the edge of the concentrating system facing the sun to be focused into the reaction device, resulting in low light energy utilization and thus affecting the hydrogen production rate. Summary of the Invention

[0004] The purpose of this invention is to provide a multimodal disk and its photothermal hydrogen production device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multimodal disk, comprising: The base has a first support ring and a second support ring arranged sequentially from top to bottom along its axial direction; A first support ring, on which several sets of first rods are rotatably connected, and at the bottom of each first rod is a first flipping assembly, and the first flipping assembly is slidably connected to a first movable ring; A second support ring is rotatably connected to a number of second rods, and a second flipping assembly is provided at the bottom of the second rods. The second flipping assembly is slidably connected to a second movable ring. The base is equipped with a first driving component for driving the first movable ring to move along the axial direction of the base, and a second driving component for driving the second movable ring to move along the axial direction of the base. The top surfaces of the first and second rods are each equidistantly fitted with a number of first light-concentrating plates and a number of second light-concentrating plates along their own length direction.

[0006] Preferably, a plurality of the first rods are distributed at equal angles around the first support ring, and a plurality of the second rods are distributed at equal angles around the second support ring, with the first rods and the second rods being distributed in an alternating manner.

[0007] Preferably, a plurality of the first light-concentrating plates and a plurality of the second light-concentrating plates are staggered in the horizontal direction.

[0008] Preferably, one end of the first rod is provided with a first ring sleeve that is sleeved with the first support ring; One end of the second rod is provided with a second ring sleeve that is sleeved with the second support ring.

[0013] A photothermal hydrogen production device, comprising the multimodal disk as described in any one of claims 1-8.

[0014] Compared with the prior art, the present invention provides a multimodal disk and its photothermal hydrogen production device, which has the following beneficial effects: This invention utilizes first and second support rings at different heights. A first rod is mounted on the first support ring, and a first concentrator plate is installed on the first rod. A second rod is mounted on the second support ring, and a second concentrator plate is installed on the second rod. A first driving element drives a first movable ring, which in turn moves all the first rods. A second driving element drives a second movable ring, which in turn moves all the second rods. This allows the two sets of concentrator plates to independently adjust their angles and converge towards the central axis of the base. This enables the concentrator to focus as much sunlight as possible onto the concentrator area during solar tracking, providing a stable photothermal energy input for the subsequent photothermal hydrogen production reaction.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0019] like Figure 1 - Figure 5 As shown, a multimodal disk includes: Base 1, with a first support ring 2 and a second support ring 5 arranged sequentially from top to bottom along its axial direction; A first support ring 2 is rotatably connected to a number of first rods 3. The bottom of the first rods 3 is provided with a first flipping assembly 302. The first flipping assembly 302 is slidably connected to a first movable ring 4. In use, the first support ring 2 is fixedly connected to the base 1, and the first rods 3 are rotatably connected to the first support ring 2, so that the first rods 3 can rotate around the first support ring 2 as the rotation center axis, thereby adjusting the angle of the first rods 3. The second support ring 5 has several sets of second rods 6 rotatably connected to it. The bottom of the second rod 6 is provided with a second flipping assembly 602. The second flipping assembly 602 is slidably connected to a second movable ring 7. Similarly, the second support ring 5 is fixedly connected to the base 1, and the second rod 6 is rotatably connected to the second support ring 5, so that the second rod 6 can rotate around the second support ring 5 as the rotation center axis, thereby adjusting the angle of the second rod 6. The base 1 is equipped with a first driving member 8 that drives the first movable ring 4 to move along the axial direction of the base 1, and a second driving member 9 that drives the second movable ring 7 to move along the axial direction of the base 1. The top surfaces of the first rod 3 and the second rod 6 are respectively equidistantly installed with a number of first concentrating plates 301 and a number of second concentrating plates 601 along their own length direction. In use, the surfaces of the first concentrating plates 301 and the second concentrating plates 601 are coated with high reflectivity, which can efficiently capture incident light at different angles and reflect it to the concentrator of the photothermal hydrogen production equipment.

[0020] In use, when the first driving member 8 drives the first movable ring 4 to move upward along the base 1 axis, the first movable ring 4 drives the first rod 3 to rotate around the first support ring 2 through the first flipping assembly 302, thereby adjusting the upward tilt angle of the first light-concentrating plate 301; similarly, when the second driving member 9 drives the second movable ring 7 to move upward, the upward tilt angle of the second light-concentrating plate 601 can be adjusted through the second flipping assembly 602, which can be flexibly adjusted to change the incident angle of sunlight shining on the light-concentrating plate, so that the light-concentrating plate can reflect more light onto the light-concentrating device.

[0021] The first movable ring 4 and the second movable ring 7 can be controlled independently, so that the angle adjustment of the first concentrator 301 and the second concentrator 601 does not interfere with each other. The angle of the two sets of concentrators can be adjusted according to the position of the sun during the day to achieve efficient light concentration and maximum area concentration.

[0022] Furthermore, a number of first rods 3 are distributed at equal angles around the first support ring 2, and a number of second rods 6 are distributed at equal angles around the second support ring 5, with the first rods 3 and the second rods 6 being staggered to avoid interference when the first rods 3 and the second rods 6 rotate.

[0023] Furthermore, a plurality of first light-concentrating plates 301 and a plurality of second light-concentrating plates 601 are staggered in the horizontal direction. In use, the first rod 3 and the second rod 6 are staggered, and the first light-concentrating plates 301 and the second light-concentrating plates 601 are also staggered in the horizontal direction, so that the first light-concentrating plates 301 and the second light-concentrating plates can form complementary light-concentrating areas when the angle is adjusted, effectively reducing the mutual obstruction of light.

[0024] Furthermore, one end of the first rod 3 is provided with a first ring sleeve 303 that is sleeved with the first support ring 2; The second rod 6 has a second ring sleeve 603 at one end that is sleeved with the second support ring 5. The inner walls of the first ring sleeve 303 and the second ring sleeve 603 are both provided with bushings to reduce rotational damping and make rotation smoother.

[0025] Furthermore, the first flipping assembly 302 includes a first guide rod 3021 arranged along the length direction of the first rod 3. A first sliding sleeve 3022 is slidably connected to the first guide rod 3021. The first sliding sleeve 3022 is rotatably connected to the first movable ring 4. In use, when the first movable ring 4 moves along the axial direction of the base 1, the first movable ring 4 drives the first sliding sleeve 3022 to slide on the first guide rod 3021. Since the first sliding sleeve 3022 is rotatably connected to the first movable ring 4, the first rod 3 can drive several first rods 3 to rotate synchronously relative to the first support ring 2, thereby realizing the precise adjustment of the tilt angle of the first light-concentrating plate 301. The second flipping assembly 602 includes a second guide rod 6021 arranged along the length of the second rod 6. A second sliding sleeve 6022 is slidably connected to the second guide rod 6021. The second sliding sleeve 6022 is rotatably connected to the second movable ring 7. The working principle of the second flipping assembly 602 is the same as that of the first flipping assembly 302, ensuring that the second light-concentrating plate 601 can also be angled.

[0026] Furthermore, the diameter of the second movable ring 7 is larger than that of the first movable ring 4. In use, the first movable ring 4 and the second movable ring 7 are both concentrically arranged around the base 1. The second movable ring 7 is located below the bottom of the first movable ring 4. The diameter of the second movable ring 7 is larger than that of the first movable ring 4, so that the first movable ring 4 and the second movable ring 7 will not cause structural interference when they move axially, thus ensuring the independence of the angle adjustment of the first focusing plate 301 and the second focusing plate 601.

[0027] Furthermore, the first driving member 8 is hinged to the base 1, and the output end of the first driving member 8 is rotatably connected to the first movable ring 4; The second driving component 9 is hinged to the base 1, and the output end of the second driving component 9 is rotatably connected to the second movable ring 7. In use, the hinge point of the first driving component 8 and the base 1, as well as the rotatable connection of its output end to the first movable ring 4, enable the first driving component 8 to adapt to angle changes during extension and retraction, and stably drive the first movable ring 4 to move upward along the central axis of the base 1. Similarly, the second driving component 9 stably drives the second movable ring 7 to move upward along the central axis of the base 1, thus avoiding drive jamming.

[0028] Furthermore, a first driven member 10 is installed between the base 1 and the first movable ring 4. In use, the first driven member 10 and the first driving member 8 are distributed around the base 1 in the circumference and together provide support and guidance for the first movable ring 4, preventing the first movable ring 4 from tilting or shaking during axial movement, thereby improving the stability of the angle adjustment of the first focusing plate 301. A second follower 11 is installed between the base 1 and the second movable ring 7. The second follower 11 and the second driving member 9 are distributed around the base 1 and together provide support and guidance for the second movable ring 7, preventing the second movable ring 7 from tilting or shaking during axial movement, thus improving the stability of the angle adjustment of the second focusing plate 601.

[0029] Specifically, the first driven member 10 and the second driven member 11 can be passive pneumatic rods or passive hydraulic rods, while the first driving member 8 and the second driving member 9 can be active pneumatic cylinders or active hydraulic rods.

[0030] A photothermal hydrogen production device includes a multimode disk. During operation, the device can drive the multimode disk to rotate around the central axis of a base 1 and adjust its pitch angle around the connection point between the multimode disk and the device as the origin, thus tracking the sun's trajectory and achieving efficient all-day solar concentrating. The device also includes a concentrator positioned above the central axis of the base 1, opposite the multimode disk, to collect the photothermal energy reflected by the concentrator. Furthermore, the device includes components such as a hydrogen storage tank, an electrolyzer, and a heat exchanger. The photothermal energy collected by the concentrator heats water in the electrolyzer, generating high-temperature, high-pressure steam, which drives an electrolysis reaction to produce hydrogen and oxygen. The hydrogen is purified and stored in the storage tank, while the oxygen can be directly discharged or collected for reuse.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
