A Chinese utility model patent with authorization announcement number CN204043043U discloses a solid electric heat storage heating device, which includes a housing and a heat storage unit disposed within the housing. The heat storage unit is an electric heat storage unit, including a solid heat storage material and an electric heating element. The heat storage unit is also equipped with an electrical box, i.e., a power distribution module, to supply power to the electric heating element. A heat exchange cavity is formed between the heat storage unit and the housing wall. A heat exchanger is disposed below the heat storage unit. The heat exchange air duct of the heat exchanger is connected to the heat exchange cavity, and under the action of a fan, hot air can circulate to exchange heat with the circulating water in the heat exchanger.

[0003] This heat storage device achieves heat storage and heating through electric heating, getting rid of traditional coal-fired boilers in regional heating occasions. However, this heat storage device relies on mains power supply. For the heat-using units of industrial enterprises, there are situations where the heat power supply is dispersed and the heat use cycle is not uniform. This means that when a solid heat storage device is installed in a location with a heat power supply, the heating system requires auxiliary cooperation from the factory pipeline network, especially when only remote heat-using units use heat, which greatly increases the system's operation and maintenance costs. Utility Model Content

[0004] The purpose of the utility model is to provide a solar solid heat storage heating device to solve the problem that the existing heat storage device depends on the mains power supply and cannot be flexibly used in different areas.

A solar power generation panel is mounted on the mounting base, which is connected to the power distribution module and supplies power to the power distribution module.

[0006] Furthermore, the installation base is a rectangular parallelepiped structure, the heat exchange module, the electric heat storage module and the power distribution module are all arranged inside the rectangular parallelepiped structure, and the solar power generation panel is installed on the top of the rectangular parallelepiped structure.

[0007] Furthermore, the solar panel is mounted on at least one long side of the rectangular structure so as to rotate around a horizontal axis, and a retaining structure for retaining the solar panel in an inclined unfolded state and a vertically folded state is provided on the rectangular structure.

[0008] Furthermore, the retaining structure is a telescopic support rod with one end hinged to the rectangular structure and the other end connected to the solar panel.

[0009] Furthermore, a sliding component is provided at the end of the telescopic support rod, a guide rail is provided on the side of the solar panel, the sliding component is matched with the guide rail for guiding sliding, and a locking member is provided on the sliding component to lock it on the guide rail.

[0015] The solar solid thermal storage heating device of the present invention improves upon existing electric thermal storage devices. By configuring a solar power generation panel on the electric thermal storage device, the solar power generation panel can use the electricity generated by solar energy to power the distribution module of the electric thermal storage module, thereby enabling the electric thermal storage module to generate and store thermal energy. This electric thermal storage device can break free from the limitations of a fixed power source and can generate electricity, generate heat, and store heat wherever sunlight can reach during the day, significantly reducing construction and operation and maintenance costs.

DETAILED DESCRIPTION

[0020] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0021] The solar solid heat storage heating device of the present invention is mainly an improvement to the problem that the existing electric heat storage device needs to use the mains electricity to generate heat. Since the mains power supply is often arranged in a fixed location, the use area of ​​the electric heat storage device is limited and the flexibility of use is poor. The main idea of ​​the present invention is to use sunlight to generate electricity by arranging a solar power generation panel 6 on the electric heat storage device. In this way, the electric heat storage device does not need to use the mains electricity in most cases when in use. This gets rid of the limitation of the fixed location of the mains power supply. The solar solid heat storage heating device of the present invention can be directly installed in the area or equipment that needs heating in the industrial plant. Of course, based on this idea, the specific structure of the solar solid heat storage heating device is also optimized in the present invention.

[0022] Specifically, various embodiments based on the above concepts are provided below for illustration.

[0023] The embodiment of the solar solid heat storage heating device of the present utility model is as follows: Figure 1-3 As shown, the system comprises a mounting base, mounted on which are mounted an electric thermal storage module 1, a power distribution module, and a heat exchange module that exchanges heat with the electric thermal storage module 1 and supplies heat to a heat-using location. This structure is generally similar to the prior art cited in the background art. In this embodiment, the electric thermal storage module 1 includes an insulation box 2 and a solid thermal storage material mounted therein. The solid thermal storage material is provided with an electric heating element for heating it. The electric heating element is connected to a power distribution control box 5, i.e., the power distribution module, which controls and supplies power to the module. The heat exchange module includes a heat exchanger 3, and an air inlet channel and an air outlet channel are connected to the shell of the heat exchanger 3. A heat exchange coil is installed in the shell of the heat exchanger 3. Both ends of the heat exchange coil extend out of the shell of the heat exchanger 3, and one end is a water inlet 9 and the other end is a water outlet 10. The air inlet channel and the air outlet channel are respectively connected to the inner cavity of the insulation box 2, and there are air inlet 7 and air outlet 8 in the inner cavity of the insulation box 2 respectively. There is a gap between the solid heat storage material and the side walls and top wall of the insulation box 2, forming an air circulation channel.

[0024] After the electric heating element heats the thermal storage material, it stores heat energy and maintains a high temperature. When external heat supply is needed, the fan 4 and the heat exchanger 3 circulation circuit are activated. The fan 4 forces air to circulate between the inner cavity of the thermal insulation box 2 and the inner cavity of the heat exchanger 3 shell. This causes the high-temperature air in the inner cavity of the thermal insulation box 2 to flow into the inner cavity of the heat exchanger 3 shell and exchange heat with the heat exchange coil. The water in the heat exchange coil is heated and transported to the heat-demanding area through the heat exchanger 3 circulation circuit. The low-temperature air after heat exchange enters the inner cavity of the thermal insulation box 2 and is heated again by the solid thermal storage material to high-temperature air. This achieves external heat supply.

[0025] In this embodiment, the key improvement is that a solar panel 6 is installed on the mounting base, and the solar panel 6 is connected to the power distribution module, and the power distribution module is provided with an inverter to achieve AC-DC conversion. By powering the power distribution module with the solar panel 6 installed on the mounting base, there is no need for a mains power supply. Specifically, when designing the structure, it is preferred to set the mounting base to a rectangular structure, such as a rectangular frame or a rectangular box structure, so that the heat exchange module, the electric heat storage module 1 and the power distribution module are all arranged inside the rectangular structure, and the solar panel 6 is installed on the top of the rectangular structure to better receive sunlight. Of course, in order to improve the power generation capacity, in a preferred embodiment, the solar panel 6 can also be installed on the long side of the rectangular structure. Of course, both long sides of the rectangular structure can be installed with the solar panel 6 or at least one can be installed with the solar panel 6.

[0026] When installing the solar panel 6 on the long side, in order to better receive sunlight, the solar panel 6 is generally rotated around the horizontal axis and installed on the rectangular structure, and a retaining structure is configured at the same time, so that the solar panel 6 can be flipped around the rotation axis to a suitable angle that can better receive sunlight. After being in the tilted and unfolded state, it is maintained at this angle by the retaining structure. When the solar panel 6 on the side is not in use, it is flipped to the vertical folded state, that is, the state that fits the long side of the rectangular structure, and then it is maintained in this position by the retaining structure to avoid arbitrary swinging.

[0027] To allow for greater adjustment of the solar panel 6's angles, it is preferably pivotally mounted at the top of the long side of the rectangular structure. The retaining structure includes a support rod hinged at one end to the mounting base. Support seats with recesses are distributed vertically along the back side of the solar panel 6. The free ends of the support rods are fixed within the recesses of different support seats, stably supporting the solar panel 6 at different deployment angles. The retaining structure also includes a hook connected to the mounting base. A hook ring is provided on the solar panel 6. When the solar panel 6 is in the vertically stowed position, the hook hooks the hook ring to maintain the solar panel 6 in the vertically stowed position.

[0028] In another embodiment, the retaining structure is a telescopic support rod 20 with one end hinged to the rectangular structure and the other end hinged to the solar panel 6. By adjusting the length of the telescopic support rod 20, the solar panel 6 can be maintained at different angles.

[0029] In such Figure 2 In the illustrated embodiment, to achieve greater angular adjustment of the side solar panel 6, the retaining structure comprises a support rod hinged at one end to a rectangular parallelepiped structure and a sliding member hinged at the other end. A guide rail 21 is provided on the side of the solar panel 6. The sliding member slides in a guided manner with the guide rail 21 and is equipped with a locking member that locks the sliding member to the guide rail 21. Specifically, the guide rail 21 can be a C-shaped chute, and the sliding member is a slider that slides within the C-shaped chute. A locking screw is screwed onto the side of the slider. The C-shaped chute has a long relief groove extending along its length. The locking screw passes through the relief groove and is screwed onto the slider. When tightened, it can retain the slider in a certain position in the C-shaped chute. Alternatively, the guide rail 21 can be a T-shaped chute, and the slider is a C-shaped slider. The slider is clamped to the T-shaped chute and has a jackscrew screwed onto its side. The jackscrew can press the T-shaped chute to lock the slider to the guide rail 21. At the same time, the support rod is a telescopic support rod 20. By adjusting the length of the support rod, the angle of the solar panel 6 can be adjusted without changing the locking position of the slider.

[0030] Based on the above embodiment, in a preferred embodiment, the solar panel 6 on the top of the rectangular structure is also flippably mounted thereon. A fixed support rod 15 is provided at one long side of the rectangular structure, and the solar panel 6 on the top of the rectangular structure is mounted on a support frame 18. One side of the support frame 18 is rotatably mounted around a horizontal axis with the fixed support rod 15. A telescopic support rod 20 is provided on the top of the rectangular structure on the side opposite to the fixed support rod 15 for supporting and adjusting the tilt angle of the support frame 18, thereby achieving angle adjustment of the solar panel 6 on the top. Of course, in other embodiments, the fixed support rod 15 can also be set at a position corresponding to a short side of the rectangular structure, and the telescopic support rod 20 can be set at the other short side. Alternatively, an independent flip frame can be provided at the top of the rectangular structure, and the solar panel 6 can be mounted on the flip frame to achieve angle adjustment of the solar panel 6.

[0031] like Figure 3As shown, in one embodiment, the mounting base is a rectangular frame structure, including a rectangular bottom plate 12, with columns installed at the four corners of the bottom plate 12, and a top plate fixed on the top of the columns. The relevant structure at the top of the rectangular structure is installed on the top plate, the solar panels 6 on the side are hinged to the tops of the two columns on the corresponding sides, and the support rods are installed on the columns on the corresponding sides. The electric thermal storage module 1, the power distribution module and the heat exchange module are all installed on the bottom plate 12. In order to facilitate the movement of the entire device, in this embodiment, a roller is installed at the bottom of the bottom plate 12, and the roller is a universal wheel 11, which can easily realize the movement of the entire device, making the mounting base a mobile base. Accordingly, a support hook can be set at one end of the bottom plate 12 for vehicle support. In another embodiment, on the basis of the above embodiment, a lifting structure can also be set at the edge of the bottom plate 12 for lifting and transportation, such as a lifting bolt 14.

[0032] Overall, the solar solid thermal storage heating device of this utility model can be conveniently and flexibly deployed at the desired location through its overall pre-assembly and dual transportation modes of towing and hoisting. It is particularly suitable for factories that do not require long-term heating or require internal heating in summer.
