Description

Technical Field

[0001] This invention relates to the field of energy storage and heat exchange technology, specifically to an adaptive heat storage and heat exchange component. Background Technology

[0002] In high-temperature hydrogen production using solar energy in plateau regions, large energy storage tanks are typically required to store the heat collected by the solar thermal system, thus balancing the mismatch between solar energy fluctuations and the heat demand of the hydrogen production reactor. The storage tanks are filled with a heat storage medium (such as ceramic spheres, high-temperature molten salt, or phase change material) and are permeated with heat exchange tubes. A hot medium is introduced through these tubes to heat the storage medium, or a cold medium is introduced to extract heat from it. To ensure the energy storage efficiency and minimize heat loss during storage, an external insulation structure is usually installed.

[0003] Existing insulation structures are mostly fixed insulation layers, meaning the insulation layer is installed once and its thickness and structure remain unchanged, resulting in constant insulation performance. As the core equipment for heat transfer and storage, energy storage tanks are large in size and have a large external surface area, making heat loss a particularly prominent issue. However, the environmental conditions in high-altitude areas are complex and variable: during the day, when there is ample sunlight, the solar thermal system charges the energy storage tank, causing it to reach a high temperature. If the insulation performance is too strong, heat may not be able to dissipate in time, leading to localized overheating. At night or during windy weather, the ambient temperature is low and the wind speed is high, accelerating heat loss from the energy storage tank. If the insulation performance is insufficient, heat loss will be excessive. Fixed insulation layers cannot adjust their insulation performance according to changes in ambient temperature, wind speed, and other parameters. This results in heat not being able to dissipate in time when cooling is needed, and heat loss being too rapid when insulation is needed, causing energy waste and affecting the overall efficiency of the hydrogen production system and the equipment's lifespan.

[0004] In view of this, we propose an adaptive thermal insulation energy storage heat exchange component to solve the existing problems. Summary of the Invention

[0005] The purpose of this invention is to provide an adaptive thermal insulation and energy storage heat exchange component to solve the problems mentioned in the background art.

The insulation panels are spliced ​​together to form an enclosing structure, which is used to realize the heat preservation function of the energy storage tank and to form heat dissipation channels when they are separated. A locking plate is installed to cover the joint between two adjacent insulation boards, and a connecting rod is hinged between the locking plate and one of the adjacent insulation boards. The energy storage tank is equipped with a drive mechanism, which is connected to the locking plate for driving the locking plate to move and switching the insulation plate between the insulation state and the open state. The drive mechanism is electrically connected to a controller.

[0012] Preferably, the bottom of the locking block is provided with a wedge-shaped surface. When the frame rises, the frame applies an oblique thrust toward the center of the energy storage tank to the fixing rod through the wedge-shaped surface of the locking block.

[0013] Preferably, both the insulation board and the locking board are arc-shaped boards.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention achieves adaptive adjustment of insulation performance by setting up movable insulation plates and a drive mechanism for opening and closing the insulation plates, and cooperating with the controller to automatically control the action of the drive mechanism according to the temperature signal.

[0018] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 - Figure 6 As shown, the present invention proposes an adaptive thermal insulation energy storage heat exchange component, including an energy storage tank 1, the interior of which is filled with a heat storage body, and a heat exchange tube 2 is installed through the interior of the energy storage tube. The energy storage tank 1 has a cylindrical structure and is filled with a heat storage body, which can be ceramic balls, high-temperature molten salt or phase change material, etc. The heat exchange tube 2 is installed through the interior of the energy storage tank 1. The heat exchange tube 2 is arranged in a spiral or serpentine shape inside the energy storage tank 1 and is used to introduce a heat medium to charge the heat storage body, or to introduce a cold medium to extract heat from the heat storage body. Several insulation panels 3 are movably installed around the energy storage tank 1. The insulation panels 3 are spliced ​​together to form an enclosing structure, which is used to realize the heat preservation function of the energy storage tank 1 and to form heat dissipation channels when they are separated. The multiple insulation panels 3 are movably set around the periphery of the energy storage tank 1. The insulation panels 3 are arc-shaped plates. The multiple insulation panels 3 are evenly arranged along the circumference of the energy storage tank 1. Each insulation panel 3 can be rotatably installed on the outer wall of the energy storage tank 1 around one of its edges. The multiple insulation panels 3 have two states. When each insulation panel 3 is rotated inward to splice with each other, a full circumferential heat preservation structure is formed around the energy storage tank 1. This state is the heat preservation state. When each insulation panel 3 is rotated outward to separate with each other, a heat dissipation channel is formed between adjacent insulation panels 3, and part of the outer wall of the energy storage tank 1 is exposed to the environment. This state is the open state. A locking plate 4 is installed to cover the joint between two adjacent insulation boards 3. A connecting rod 6 is hinged between the locking plate 4 and one of the adjacent insulation boards 3. Multiple locking plates 4 are set one-to-one with the insulation boards 3. Each locking plate 4 is an arc-shaped plate that covers the joint between two adjacent insulation boards 3. A connecting rod 6 is hinged between the locking plate 4 and one of the adjacent insulation boards 3. One end of the connecting rod 6 is hinged to the locking plate 4, and the other end is hinged to the adjacent insulation board 3. A drive mechanism is installed on the energy storage tank 1 and is connected to the locking plate 4 for driving the locking plate 4 to move and drive the insulation plate 3 to switch between the insulation state and the open state. The drive mechanism is installed on the energy storage tank 1 and is connected to the locking plate 4 for transmission. The drive mechanism is a linear drive mechanism 5. The linear drive mechanism 5 includes a lead screw 503, a movable rod 501 and a limit frame 502. The lead screw 503 is rotatably installed on the top of the energy storage tank 1. The movable rod 501 is threadedly connected to the lead screw 503 and is fixedly connected to the top of the locking plate 4. The limit frame 502 is fixed to the top of the energy storage tank 1. The movable rod 501 passes through the limit frame 502 and the limit frame 502 restricts the circumferential rotation of the movable rod 501 so that it can only move linearly along the axial direction. The drive mechanism is electrically connected to a controller, which is in turn electrically connected to the linear drive mechanism 5. The controller is also connected to a temperature sensor, which can be mounted on the outer wall of the energy storage tank 1 or on the insulation board 3, to detect the temperature of the energy storage tank 1 or the ambient temperature. The controller automatically controls the linear drive mechanism 5 based on the temperature signal detected by the temperature sensor.

[0020] Furthermore, the insulation plate 3 is rotatably disposed around the periphery of the energy storage tank 1, and multiple insulation plates 3 are evenly arranged along the circumference of the energy storage tank 1, with the number of locking plates 4 corresponding one-to-one with the number of insulation plates 3.

[0021] Furthermore, the driving mechanism is a linear drive mechanism 5, which includes a lead screw 503. The lead screw 503 is rotatably mounted on the top of the energy storage tank 1. The lead screw 503 is threadedly connected to a movable rod 501, and the movable rod 501 is fixedly connected to the locking plate 4. A limit bracket 502 is fixedly mounted on the top of the energy storage tank 1 to limit the circumferential rotation of the movable rod 501.

[0022] Furthermore, a worm gear 504 is fixedly mounted on the lead screw 503, a worm 505 is movably mounted on the energy storage tank 1 and meshes with the worm gear 504, a gear ring 507 is rotatably mounted on the energy storage tank 1, a gear 506 is fixedly mounted at the end of the worm 505 and meshes with the outer side of the gear ring 507, a gear 508 meshes with the inner side of the gear ring 507, and a rotary drive 509 is mounted on the energy storage tank 1 and the output end of the rotary drive 509 is fixedly connected to the gear 508.

[0023] A worm gear 504 is fixedly mounted on the upper end of a lead screw 503. A worm 505 is rotatably mounted on the top of the energy storage tank 1 and meshes with the worm gear 504. A gear 506 is fixedly mounted on the end of the worm 505. A ring gear 507 is a circular ring structure and is rotatably mounted on the energy storage tank 1. The outer side of the ring gear 507 has external teeth that mesh with the gear 506, and the inner side of the ring gear 507 has internal teeth. A gear 508 meshes with the inner side of the ring gear 507. A rotary drive 509 is mounted on the energy storage tank 1, and its output end is fixedly connected to the gear 508. The rotary drive 509 can be a motor. Multiple gears 506 are provided, and the multiple gears 506 are arranged at intervals along the circumference of the energy storage tank 1. Each gear 506 is connected to a worm 505 and a lead screw 503. The multiple lead screws 503 are respectively connected to... Multiple locking plates 4 are engaged by movable rods 501. The rotary drive 509 drives the gear ring 507 to rotate via gear 2 508. The gear ring 507 simultaneously drives multiple gears 1 506 to rotate synchronously via its outer teeth. Gear 1 506 drives the worm 505 to rotate, the worm 505 drives the worm wheel 504 to rotate, and the worm wheel 504 drives the lead screw 503 to rotate, thereby realizing the synchronous movement of multiple locking plates 4. Through the engagement of the gear ring 507 and multiple gears 1 506, a single rotary drive 509 can simultaneously drive multiple locking plates 4 to move synchronously, simplifying the drive structure and reducing control complexity. At the same time, the engagement of the worm 505 and the worm wheel 504 has a self-locking characteristic. When the rotary drive 509 stops working, the lead screw 503 is locked, and the insulation plate 3 maintains its current open / closed state without the need for additional energy consumption.

[0024] The rotational power output by the rotary drive component 509 is transmitted sequentially through gear 2 508, gear ring 507, gear 1 506, worm 505, and worm wheel 504 to the lead screw 503, which drives the locking plate 4 to move.

[0025] Furthermore, a locking mechanism 7 is installed at the bottom of the energy storage tank 1 to lock the position of the locking plate 4 when the insulation plate 3 is in the insulation state.

[0026] Furthermore, the locking mechanism 7 includes a fixing rod 701, which is fixedly installed on the bottom of the locking plate 4. A locking block 705 is fixedly installed at the lower end of the fixing rod 701. A frame 702 is lifted and installed at the bottom of the energy storage tank 1. The frame 702 is provided with a slot 704 corresponding to the locking block 705. A linear drive 703 is installed at the bottom of the energy storage tank 1, and the output end of the linear drive 703 is connected to the frame 702 for driving the frame 702 to rise and fall.

[0027] Furthermore, the bottom of the locking block 705 is provided with a wedge-shaped surface. When the enclosure 702 rises, the enclosure 702 applies an oblique thrust toward the center of the energy storage tank 1 to the fixing rod 701 through the wedge-shaped surface of the locking block 705.

[0028] The fixing rod 701 is fixedly installed at the bottom of the locking plate 4 and moves up and down with the locking plate 4. The locking block 705 is fixedly installed at the lower end of the fixing rod 701. The bottom of the locking block 705 is provided with a wedge-shaped surface, that is, the cross-sectional dimension of the lower end of the locking block 705 gradually decreases from top to bottom. The enclosure 702 is a ring structure and is installed at the bottom of the energy storage tank 1 in a liftable manner. The enclosure 702 surrounds the energy storage tank 1. The enclosure 702 is provided with a slot 704 corresponding to the locking block 705. The shape of the slot 704 matches the locking block 705. The linear drive 703 is installed at the bottom of the energy storage tank 1. Its output end is connected to the enclosure 702 and is used to drive the enclosure 702 to move up and down. The linear drive 703 can be a cylinder or an electric push rod.

[0029] When the insulation plate 3 is in the insulation state, the locking plate 4 moves to the position that best fits the energy storage tank 1. The fixing rod 701 and the locking block 705 move synchronously. At this time, the linear drive 703 drives the frame 702 to rise, so that the locking block 705 is locked into the slot 704. Since the bottom of the locking block 705 is provided with a wedge-shaped surface, during the rise of the frame 702, the wedge-shaped surface of the locking block 705 applies an oblique thrust toward the center of the energy storage tank 1 to the fixing rod 701. This thrust is transmitted to the locking plate 4 through the fixing rod 701, and then to the insulation plate 3 through the connecting rod 6, further pressing the insulation plate 3 against the outer wall of the energy storage tank 1, while locking the position of the locking plate 4 to prevent it from loosening due to vibration or external force.

[0030] When it is necessary to open the insulation plate 3, the linear drive component 703 drives the frame 702 to descend, causing the locking block 705 to disengage from the slot 704, releasing the locking plate 4. The linear drive mechanism 5 can then move the locking plate 4 to open the insulation plate 3.

[0031] By setting the locking mechanism 7, the locking plate 4 is mechanically locked when the insulation plate 3 is in the insulation state, which improves the structural stability under the insulation state, prevents the insulation plate 3 from being accidentally opened due to external forces such as strong winds at high altitudes, and further enhances the insulation effect.

[0032] Furthermore, both the insulation board 3 and the locking board 4 are curved boards.

[0033] The insulation board 3 adopts a multi-layer composite structure, including an inner reflective layer, a middle aerogel insulation layer, and an outer metal protective layer. The reflective layer is made of polished aluminum plate or silver-plated stainless steel plate to reflect radiant heat. The aerogel insulation layer has an extremely low thermal conductivity, making it suitable for high-altitude and cold environments. The metal protective layer is made of weathering steel to resist the erosion of strong winds and sandstorms in high-altitude areas. The locking board 4 also adopts an arc-shaped board structure, with an elastic sealing gasket on its inner surface. When the locking board 4 covers the joint between two adjacent insulation boards 3, the elastic sealing gasket is tightly fitted to the outer surface of the insulation board 3, further reducing heat loss at the joint. In response to the characteristics of large diurnal temperature differences, strong winds and sandstorms, and strong ultraviolet radiation in high-altitude areas, the insulation board 3 and the locking board 4 have been specifically designed to improve the durability and insulation performance of the equipment in harsh environments. In the insulation state, the elastic sealing gasket on the inner side of the locking board 4 is fitted to the outer surface of the insulation board 3, forming a tighter sealing structure and reducing heat loss from the joint.

[0034] Working principle: When the temperature sensor detects that the temperature of the energy storage tank 1 is too high and heat dissipation is required, the controller controls the linear drive mechanism 5 to start, the lead screw 503 rotates, driving the movable rod 501 to move linearly, the movable rod 501 drives the locking plate 4 to move, when the locking plate 4 moves away from the energy storage tank 1, it pulls the insulation plate 3 to rotate outward through the connecting rod 6, so that the adjacent insulation plates 3 separate from each other and form a heat dissipation channel. At this time, part of the outer wall of the energy storage tank 1 is exposed, and heat can be dissipated to the environment through the heat dissipation channel. When the temperature sensor detects that the temperature of the energy storage tank 1 is too low and needs to be kept warm, the controller controls the linear drive mechanism 5 to move in the opposite direction. The lead screw 503 rotates in the opposite direction, driving the movable rod 501 to move linearly. The movable rod 501 drives the locking plate 4 to move closer to the energy storage tank 1. When the locking plate 4 moves, it pushes the insulation plate 3 to rotate inward through the connecting rod 6, so that the adjacent insulation plates 3 are spliced ​​together to form a full-circumference insulation structure surrounding the energy storage tank 1. At the same time, the locking plate 4 covers the joint of the adjacent insulation plates 3, blocking the joint and reducing the loss of heat from the joint.

[0035] The above specific embodiments are merely several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
