Description

Technical Field

[0001] This invention belongs to the field of energy storage equipment, and more specifically, relates to an energy storage tank that utilizes both solar and geothermal energy. Background Technology

[0002] Both solar and geothermal energy fall under the category of clean, renewable energy sources. Therefore, current technologies often utilize heat exchangers in conjunction with water as the medium for their development and utilization, such as water storage tanks with internal heat exchangers. While existing heat storage tank structures are diverse, the following points must be considered regardless of the structure: first, heat exchange efficiency; second, maintaining a constant water temperature at the outlet during the heating process; and third, preventing the water tank from being damaged by the impact of incoming water over a period of time. Increasing the internal volume of the water storage tank can effectively reduce the impact of incoming water, but it inevitably leads to a decrease in heat exchange efficiency.

[0034] Preferred embodiments of the invention will now be described in more detail. While preferred embodiments of the invention are described below, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0035] This invention provides an energy storage tank for the combined use of solar and geothermal energy, comprising:

[0036] The insulated box has a base at the bottom, and the inside of the insulated box is used to hold liquid;

[0037] An energy storage mechanism is installed inside the insulation box, with its bottom extending into the base. The energy storage mechanism includes a heating component and a control component. The heating component includes a heat-conducting seat and a heat-absorbing seat that moves vertically. The heat-conducting seat is located at the top of the insulation box and is used to receive heat energy. When the heat-conducting seat and the heat-absorbing seat are in contact, the heat-absorbing seat can heat the liquid. The control component includes a moving frame and an electromagnet. The moving frame is connected to the heat-absorbing seat through a sliding tube. An air bladder is provided on the moving frame. When the electromagnet is energized, it can attract the moving frame to move downwards, causing the heat-conducting seat and the heat-absorbing seat to separate.

[0038] Specifically, the energy storage tank is equipped with a heating component and a control component inside the insulation box. The heating component is fixed by the contact of a heat-conducting seat and a heat-absorbing seat, transferring heat from the heat-conducting seat to the heat-absorbing seat. Then, through the heat-absorbing seat and other structures of the heating component, the liquid inside the insulation box is heated, and the thermal energy is stored inside the insulation box. In addition, the air bladder in the control component can cause the air bladder to move the moving frame upward. The moving frame then pushes the heat-absorbing seat to the heat-conducting seat through a sliding tube, thus transferring heat into the insulation box. When the electromagnet in the control component is energized, it can magnetically attract the moving frame and make it move downward. Under the connection of the sliding tube, the heat-absorbing seat and the heat-conducting seat are separated, cutting off the heat conduction path and preventing the heat in the insulation box from being lost through the heat-conducting seat.

[0039] Optionally, the heating assembly also includes:

[0040] Multiple heat-conducting plates are arranged along the length of the sliding tube;

[0041] Multiple heat-conducting rods are arranged on the outer periphery of the sliding tube. Each heat-conducting rod passes through the heat-conducting plate, and the upper end of the heat-conducting rod is connected to the lower side of the heat-absorbing base.

[0042] Specifically, the heating assembly also includes multiple heat-conducting discs and rods. These discs and rods act as heat transfer media, conducting heat to the liquid inside the insulation box. The top of the sliding tube is connected to the lower side of the heat absorber base, and the sliding tube is perpendicularly connected to the center of the heat absorber base. Multiple heat-conducting discs are also fitted onto the sliding tube, which passes through the center of all the discs. Multiple heat-conducting rods are arranged around the outer periphery of the sliding tube, parallel to it. Since each rod passes through all the discs, its top is connected to the heat absorber base, and its middle is connected to each disc. This allows heat from the heat absorber base to be transferred to each disc, increasing the heat transfer area to the liquid inside the insulation box and improving heat storage efficiency.

[0043] In one embodiment, the heat-conducting rods are arranged from the center outward on the outer periphery of the sliding tube. The sliding tube is connected to the heat-absorbing base and all the heat-conducting plates, serving as a fixed connection. The heat-conducting rods are connected to the heat-absorbing base and all the heat-conducting plates to transfer the heat obtained by the heat-absorbing base from the heat-conducting base to each heat-conducting plate. The diffused arrangement of the heat-conducting rods can improve the heat transfer rate of the heat-conducting plates.

[0044] Optionally, the heat conduction plate has a structure that is sharp at the bottom and wide at the top, and multiple bottom strips are provided on the lower side of the heat conduction plate, with all bottom strips distributed in a ring.

[0045] Specifically, the liquid inside the insulation box is heated by a heat-absorbing base, a heat-conducting rod, and a heat-conducting plate. The heat-conducting plate can provide uniform auxiliary heating to the liquid. The shapes set at the top and bottom of the heat-conducting plate can make the heated liquid move upward, while the bottom strip at the bottom of the heat-conducting plate can assist the movement of the heated liquid.

[0046] Optionally, each heat-conducting plate has a groove on its outer periphery, and each heat-conducting plate has a corresponding groove. A sliding frame is installed through the inner wall of all grooves, and the sliding frame slides in cooperation with the guide strip on the inner side of the insulation box.

[0047] Specifically, multiple parallel heat-conducting plates are equipped with sliding frames on their outer periphery. The sliding frames fit snugly against the inner wall of the slot of each heat-conducting plate, ensuring that the relative positions of the multiple heat-conducting plates do not change. This makes the heat-absorbing base, heat-conducting rod, and heat-conducting plates form an integral structure. The sliding frames are locked in place with the guide strips on the insulation box. When heating liquid, the heated liquid flows between the bottom strips without causing the heat-conducting plates to rotate, ensuring a stable heat conduction path between the heat-conducting base, the heat-absorbing base, and the structure below.

[0048] Optionally, multiple guide bars and sliding frames are provided along the circumference of the heat-conducting plate.

[0049] Optionally, the control component also includes:

[0050] The lower end of the sliding rod is connected to the fixed base, and the upper end of the sliding rod is inserted into the inside of the sliding tube.

[0051] The movable frame is ring-shaped and is fitted around the outer periphery of the sliding rod. Multiple iron frames are set at the center of the movable frame, and the iron frames are arranged along the radial direction of the movable frame. Airbags are set between adjacent iron frames.

[0052] Specifically, the control component is used to adjust the on / off state of the heat conduction path between the heat-conducting seat and the heat-absorbing seat. A sliding rod is slidably installed inside the sliding tube, and a fixed seat is installed at the lower end of the sliding rod. The moving frame is sleeved on the outer periphery of the sliding rod. When the electromagnet is not energized, the moving frame floats upward under the action of its own airbag. The moving frame will push the heat-absorbing seat to fit against the heat-conducting seat. In this way, the heating group heats the liquid in the heat preservation box, realizing heat storage. When the heat-conducting seat cannot collect external heat, the electromagnet is energized to attract the iron frame, thereby realizing that the moving frame and the iron frame move downward synchronously. In this way, the moving frame will contact the fixed seat, driving the sliding rod and the sliding tube to separate the heat-absorbing seat from the heat-conducting seat, breaking the heat transfer path between the heat-absorbing seat and the heat-conducting seat, and preventing the heat of the liquid in the heat preservation box from escaping.

[0053] Optionally, the fixing seat is conical, and the outer diameter of the large end of the fixing seat is larger than the inner diameter of the moving frame.

[0054] Specifically, the inner diameter of the movable frame is smaller than the large end of the fixed base. When the movable frame is attracted downward by the energized electromagnet, the movable frame contacts the fixed base and drives the fixed base, sliding rod and sliding tube to move downward together, thereby separating the heat-absorbing base from the heat-conducting base.

[0055] Optionally, the top of the heat-conducting base is located outside the insulation box, and a solar heating panel is provided on the top of the heat-conducting base.

[0056] Optionally, the liquid in the insulated box is geothermal water.

[0057] Specifically, this energy storage tank converts solar energy into heat through a heat-conducting base, and then heats the geothermal water in the insulated box through a heating component, thus storing solar heat for convenient subsequent use of the solar and geothermal water heat. When the heat-conducting base cannot receive solar heat, it needs to be separated from the heat-conducting base to ensure that the heat in the geothermal water does not escape. Furthermore, when the geothermal water is in contact with the heat-conducting base, the heat-conducting base will not carry heat away from the geothermal water.

[0058] Optionally, the upper and lower ends of the insulated box are respectively provided with an upper tube and a lower tube.

[0059] Specifically, after the geothermal water in the insulation box stores solar energy, it is discharged through the conduit, effectively utilizing the heat from both the solar energy and the geothermal water. Then, geothermal water is continuously added back into the insulation box to continue storing solar energy in the geothermal water.

[0060] Example

[0061] like Figures 1 to 6 As shown, the present invention provides an energy storage tank for the combined use of solar and geothermal energy, comprising:

[0062] The insulated box 1 has a base 2 at the bottom, and the inside of the insulated box 1 is used to hold liquid.

[0063] Energy storage mechanism 3 is installed inside the insulation box 1. The bottom of the energy storage mechanism 3 extends into the base 2. The energy storage mechanism 3 includes a heating component 31 and a control component 32. The heating component 31 includes a heat-conducting seat 313 and a heat-absorbing seat 312 that is movably arranged in the vertical direction. The heat-conducting seat 313 is located on the top of the insulation box 1 and is used to receive heat energy. When the heat-conducting seat 313 is in contact with the heat-absorbing seat 312, the heat-absorbing seat 312 can heat the liquid. The control component 32 includes a moving frame 323 and an electromagnet 324. The moving frame 323 is connected to the heat-absorbing seat 312 through a sliding tube 311. An airbag 326 is provided on the moving frame 323. When the electromagnet 324 is energized, the electromagnet 324 can attract the moving frame 323 to move downward, so that the heat-conducting seat 313 and the heat-absorbing seat 312 are separated.

[0064] In this embodiment, the heating component 31 further includes:

[0065] Multiple heat-conducting plates 315 are arranged along the length of the sliding tube 311;

[0066] Multiple heat-conducting rods 314 are disposed on the outer periphery of the sliding tube 311. Each heat-conducting rod 314 passes through the heat-conducting plate 315, and the upper end of the heat-conducting rod 314 is connected to the lower side of the heat-absorbing seat 312.

[0067] In this embodiment, the heat conduction plate 315 has a structure that is sharp at the bottom and wide at the top. Multiple bottom strips 317 are provided on the lower side of the heat conduction plate 315, and all bottom strips 317 are distributed in a ring.

[0068] In this embodiment, each heat conduction plate 315 is provided with a groove 316 on its outer periphery, and the groove 316 of each heat conduction plate 315 is provided accordingly. The inner wall of all grooves 316 is provided with a sliding frame 318, and the sliding frame 318 slides in cooperation with the guide strip 33 on the inner side of the heat preservation box 1.

[0069] In this embodiment, multiple guide bars 33 and sliding frames 318 are provided along the circumference of the heat-conducting disk 315.

[0070] In this embodiment, the control component 32 further includes:

[0071] The lower end of the sliding rod 322 is connected to the fixed base 321, and the upper end of the sliding rod 322 is inserted into the sliding tube 311.

[0072] The movable frame 323 is ring-shaped and is sleeved on the outer periphery of the sliding rod 322. Multiple iron frames 325 are arranged at the center of the movable frame 323. The iron frames 325 are arranged along the radial direction of the movable frame 323. Airbags 326 are arranged between adjacent iron frames 325.

[0073] In this embodiment, the fixed base 321 is conical, and the outer diameter of the large end of the fixed base 321 is larger than the inner diameter of the movable frame 323.

[0074] In this embodiment, the top of the heat-conducting base 313 is located outside the heat-insulating box 1, and a solar heating plate is provided on the top of the heat-conducting base 313.

[0075] In this embodiment, the liquid in the insulated box 1 is geothermal water.

[0076] In this embodiment, the upper tube 4 and the lower tube 5 are respectively provided at the upper and lower ends of the heat preservation box 1.

[0077] In summary, during use, the heat storage tank contacts the heat-conducting seat 313 and the heat-absorbing seat 312. The heat-absorbing seat 312, heat-conducting rod 314, and heat-conducting plate 315 heat the geothermal water inside the insulation box 1. The heat-conducting plate 315 provides uniform auxiliary heating to the liquid. Furthermore, because the heat-conducting plate 315 is pointed at the bottom and wide at the top, the heating medium can move upwards. The bottom strip 317 on the lower side of the heat-conducting plate 315 assists in the movement of the geothermal water. The sliding frame 318 and the guide strip 33 work together to prevent the heating component 31 from rotating. This process facilitates heat storage. When the buoyancy of multiple airbags 326 causes the moving frame 323 to move upward, the heat-absorbing seat 312 comes into contact with the heat-conducting seat 313, thereby achieving the effect of heat conduction and heat storage. When the outside temperature is low or there is no solar energy absorption, the electromagnet 324 is driven to generate magnetic force. Under the mutual attraction between the electromagnet 324 and the iron frame 325, the iron frame 325 drives the moving frame 323 to move downward. The heat-absorbing seat 312 is driven downward through the sliding tube 311. The heat-absorbing seat 312 does not come into contact with the heat-conducting seat 313 and forms a cavity in the gap, thus blocking the heat conduction.

[0078] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
