Description

Technical Field

[0001] The present invention relates to the technical field of energy storage, and particularly to a heat storage device. Background Art

[0002] Traditional heat storage devices mainly consist of heat storage materials, containers, and insulation structures. Their working principle is to convert the energy input from the outside into heat energy with the help of heat storage materials, containers, and insulation structures, and store it inside the device. During the heat storage process, the heat energy is mainly transferred to the heat storage materials through three ways: conduction, convection, and radiation to achieve the storage and conversion of energy. However, in the current related technical fields, the positions where the heat storage materials receive heat energy are relatively fixed, which causes local areas of the heat storage materials to continuously receive heat energy, resulting in a sharp rise in the local temperature of the heat storage materials. As the local temperature increases, the thermal resistance characteristics of the heat storage materials change significantly, and the thermal resistance gradually increases. The increase in thermal resistance directly hinders the effective transfer and storage of heat energy, ultimately leading to a significant reduction in the heat storage efficiency of the entire heat storage device, affecting the overall performance and application effect of the heat storage device.

The second rotating shaft 11 is arranged at the output end of the second driving motor 10 and is connected to the support plate 37 and the heat storage cylinder 3. The second driving motor 10 drives the second rotating shaft 11 to rotate, thereby driving the support plate 37 and the heat storage cylinder 3 to rotate. The second rotating shaft 11 penetrates through the axis positions of the support plate 37 and the heat storage cylinder 3, so that the support plate 37 and the heat storage cylinder 3 can rotate smoothly.

[0031] Furthermore, in an embodiment of the present invention, please refer to Figure 2 , Figure 3 andFigure 7 The heat storage device further includes a fixing frame 31, a fixing block 6 and a heating element.

By providing the fixing block 6, a plurality of through holes 21 can be shielded, that is, a plurality of heat storage components can be shielded. At the same time, one end of the heat storage component facing away from the fixing block 6 is blocked by the bottom plate 2, so that the heat loss of the heat storage component can be reduced and the energy loss can be reduced. The heating element slidably penetrates through the installation cylinder 1 and the fixing block 6. The position where the heating element is located is the heat supply position. The heat storage cylinder 3 can be driven to rotate by the second driving component, so that one of the heat storage components is located below the heating element, and the heat storage component can be supplied with heat by the heating element. After one heat storage component completes heat storage, the heat storage cylinder 3 can be driven to rotate in the installation cylinder 1 by the second driving component, so that the heat storage component that has completed heat storage can move below the fixing block 6, and at the same time, another heat storage component can rotate to the heat supply position to receive heat energy for heat storage, which is beneficial to increasing the heat storage capacity of the heat storage device and reducing heat loss.

[0032] In order to drive the sliding of the heating element, in an embodiment of the present invention, please refer to Figure 3 and Figure 4 The heat storage device further includes a lead screw 32, a moving block 33, a fixing column 35, a circular ring plate 34 and a connecting plate 17.

Specifically, the lead screw 32 is connected to the second rotating shaft 11 of the second driving component. The second driving motor 10 of the second driving component drives the second rotating shaft 11 to rotate. The second rotating shaft 11 drives the lead screw 32 to rotate. The rotation of the lead screw 32 causes the moving block 33 to move up and down. When the moving block 33 rises, it will drive the fixing column 35 and the circular ring plate 34 to rise. The fixing column 35 slides relative to the connecting plate 17. After the circular ring plate 34 rises to a certain position, it can contact the connecting plate 17, and then drive the connecting plate 17 to rise, and finally the connecting plate 17 drives the heating element to rise.

[0033] Furthermore, in an embodiment of the present invention, please refer to Figure 4, the heating member includes a moving column 14 and a heating column 15.

The connecting rope 16 connects the telescopic ring plate 20 and the lifting ring plate 36. The lifting ring plate 36 is slidably sleeved on the heating column 15 and is located in the lifting groove 29. Wherein, when the heating column 15 contacts the heat conducting column 5, the first spring 18 is in a compressed state.

At this time, under the action of the first spring 18, the telescopic ring plate 20 will remain stationary, so that the connecting rope 16 can pull the lifting ring plate 36 to rise. After the lifting ring plate 36 rises a certain height, it can contact the clamping block 27 on the heating column 15, and drive the heating column 15 to rise through the clamping block 27, so that the heating column 15 is received inside the moving column 14 and separated from the heat conducting column 5.

[0034] Specifically, in an embodiment of the present invention, please refer to Figure 4 , the heat storage device further includes a third spring 28. The third spring 28 is arranged between the lifting ring plate 36 and the inner top wall of the lifting groove 29.

[0035] Further, in an embodiment of the present invention, please refer to Figure 4 and Figure 8 , the heat storage device further includes a receiving block 26, two shielding blocks 23, and two second springs 24.

When the heating column 15 is located between the two shielding blocks 23, the second spring 24 is in a compressed state. Thus, after the heating column 15 is received inside the moving column 14, under the action of the second spring 24, the two shielding blocks 23 can approach and contact each other to shield the bottom of the moving block 33. Wherein, a guiding surface is formed on the shielding block 23, and when the heating column 15 moves downward, the two shielding blocks 23 can be easily pushed to slide through the guiding surface.

[0036] In an embodiment of the present invention, heat energy is conducted from an external device to the heat conducting column 5 through the heating column 15, and the heat conducting column 5 transfers the heat to the heat storage body 4 through the heat conducting block 22, so that the heat conducting block 22 evenly transfers the heat energy to the heat storage body 4, which is beneficial to evenly transfer the heat energy to the heat storage body 4 and improve the heat storage speed of the device. Start the first driving motor 13, the first driving motor 13 drives the first rotating shaft 12 to rotate, the first rotating shaft 12 drives the first gear 9 to rotate, the first gear 9 drives the second gear 7 to rotate, the second gear 7 drives the connecting shaft 8 to rotate, and the connecting shaft 8 drives the heat storage body 4 to rotate, so that the contact surface between the heat storage body 4 and the heat conducting block 22 continuously changes, and the high-temperature heat conducting column 5 continuously contacts the low-temperature surface on the heat storage body 4, which is beneficial to quickly conduct and store the heat energy in the heat storage body 4, maintain the heat conduction speed of the device, and further improve the heat storage speed of the device.

The second rotating shaft 11 drives the lead screw 32 to rotate, the lead screw 32 drives the moving block 33 to move, the moving block 33 drives the fixed column 35 to move, and the fixed column 35 drives the ring plate 34 to move. When the second rotating shaft 11 drives multiple batches of heat storage bodies 4 to finish heat storage, the ring plate 34 moves below the connecting plate 17, so that the second rotating shaft 11 drives the heat storage body 4 to continue to rotate a certain angle, the ring plate 34 drives the connecting plate 17 to move, the connecting plate 17 drives the moving column 14 to move, so that the connecting rope 16 moves, the connecting rope 16 drives the lifting circular plate to move, the lifting circular plate drives the clamping block 27 to move, and the clamping block 27 drives the heating column 15 to retract into the moving column 14, which is beneficial to separating the heat storage body 4 from the heating column 15 after the heat storage body 4 in the device finishes heat storage and moving the heat storage body 4 below the fixed block 6, preventing the heat stored in the device from being lost and reducing the energy loss.
