[0002] Clean energy, that is, green energy, refers to energy that does not emit pollutants and can be directly used in production and life, including nuclear energy and "renewable energy". Renewable energy refers to energy whose raw materials can be regenerated, such as hydropower, wind power, solar energy, bioenergy (biogas), geothermal energy (including geothermal and water sources), and tidal energy.

[0003] After retrieval, a Chinese patent with the authorization announcement number CN112942564B discloses a building energy-saving device using clean energy, including a roof. Installation frames with the same inclination angle as the two slopes of the roof are provided on both slopes. A fixing frame suitable for its structure is provided on the installation frame. One end of the installation frame close to the ridge is hinged to the fixing frame. An airbag plate is provided inside the fixing frame. An air pipe communicated with the airbag plate is provided on the airbag plate. A cavity is provided inside the wall. One end of the air pipe away from the airbag plate extends into the cavity, forming a structure in which the heat absorbed by the airbag plate is transferred to the inside of the wall through the air pipe. A heat dissipation plate is provided at one end of the cavity away from the airbag, solving the problems that in the prior art, self-built houses in cold regions, especially in rural areas, cannot meet people's temperature requirements by relying on sunlight in good weather and the solar energy utilization rate on the back of the ridge is relatively low due to seasonal factors. This patent has good applications in the construction field.

Detailed implementation manners

[0033] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] The present invention provides a building energy-saving device using clean energy by improvement. The technical solution of the present invention is as follows:

[0035] As Figures 1 to 9 shown, the embodiment of the present invention provides a building energy-saving device using clean energy, including an energy-saving component 1. The energy-saving component 1 includes an external shell 101. The entire external shell 101 is made of heat-insulating material and is installed on the roof;

[0036] Specifically, the interior of the external shell 101 is composed of a plurality of horizontally placed cuboid frames 108 (as Figure 4As shown, groove plates 115 are provided at the top and bottom inside the cuboid frame 108. The groove plates 115 are metal plates, and the selection of metal plates mainly improves the strength of the groove plates 115.

[0037] More specifically, a refrigeration structure 106 for refrigeration and a heating structure 109 for heating are respectively provided in the two groove plates 115 inside each cuboid frame 108. A displacement mechanism is provided at one end of each cuboid frame 108, and the displacement mechanism displaces the positions of the two groove plates 115 inside the cuboid frame 108 where it is located; in a summer environment, through the displacement mechanism, the groove plate 115 equipped with the refrigeration structure 106 is placed at the top of the external shell 101, and the groove plate 115 equipped with the heating structure 109 is placed at the bottom of the external shell 101. In a winter environment, through the displacement mechanism, the groove plate 115 equipped with the heating structure 109 is placed at the top of the external shell 101, and the groove plate 115 equipped with the refrigeration structure 106 is placed at the bottom of the external shell 101. A driving mechanism for synchronously operating each displacement mechanism is provided inside the external shell 101.

[0038] More specifically, a flow guiding component is provided on one side of the external shell 101. The flow guiding component is connected to the interior of the house, and the flow guiding component introduces external air flow into the external shell 101. The refrigeration structure 106 cools the interior of the external shell 101. The air flow forms a cold air flow when flowing through the external shell 101, and then the cold air flow is led out of the external shell 101 (entering the house to cool the house). A heat dissipation component is provided outside the external shell 101. The heat dissipation component is arranged inside the house. Each heating structure 109 is connected to the heat dissipation component, and the heat dissipation component dissipates the heat generated by the heating structure 109, that is, dissipates the heat to the house to heat the house.

[0039] Combined with the attached Figure 9 As shown, the above-mentioned refrigeration structure 106 includes porous hydrophilic filler 127. The porous hydrophilic filler 127 is embedded in the groove of the groove plate 115. The porous hydrophilic filler 127 can be selected as porous gel. In a humid and hot environment, the porous hydrophilic filler 127 will take away the moisture in the air to dry the air. In a hot environment, the moisture of the porous hydrophilic filler 127 evaporates, and the evaporation absorbs heat for refrigeration, thereby refrigerating the interior of the external shell 101. At the same time, at night or in the early morning when the temperature is low, the porous hydrophilic filler 127 absorbs the morning dew for daytime use to achieve energy saving.

[0040] Specifically, combined with the attached Figure 9 As shown, the refrigeration structure 106 further includes a radiative cooling material 126. The radiative cooling material 126 is laid on the outer surface of the porous hydrophilic filler 127. The radiative cooling material 126 is a prior art, that is, it uses an object to radiate energy to the outside to reduce the temperature, thereby dissipating heat inside the shell.

[0041] More specifically, the refrigeration structure 106 further includes a sealed bag 128 and a cold storage material 129. The cold storage material 129 is a phase change material, which is a prior art. The type of the phase change material is not selected here and is mainly selected according to the region. The cold storage material 129 is filled in the sealed bag 128, and the sealed bag 128 is embedded inside the porous hydrophilic filler 127. When the inside of the external shell 101 is refrigerated, the cold storage material 129 is refrigerated to form cooling crystals and store cold energy. When it is difficult to reduce the heat of the external shell 101, the cold storage material 129 melts from the crystals and absorbs heat to release cold energy, thereby further improving energy conservation. At the same time, when the temperature is low in the early morning, the cold storage material 129 is refrigerated to form cooling crystals for use in the hot daytime environment to release cold energy and improve the energy utilization rate.

[0042] Combined with the attached Figure 8 As shown, the above-mentioned heating structure 109 includes a concave reflector 113 and a solar water heating pipe 114. The solar water heating pipe 114 is a prior art and is heated by sunlight. The concave reflector 113 is fixed in the groove of the groove plate 115. The two ends of the solar water heating pipe 114 are respectively fixed at the two ends of the groove plate 115, and the solar water heating pipe 114 is located at the middle position of the notch of the concave reflector 113. The sunlight is refracted by the concave reflector 113 onto the solar water heating pipe 114 for heating by the sunlight.

[0043] Specifically, the heat dissipation assembly includes two shunt pipes 102, one heat exchange pipe 3 and one circulation water pump 4. The pipe bodies of the two shunt pipes 102 are respectively fixed at the two ends of the external shell 101. Each branch pipe of the shunt pipe 102 is connected to each solar water heating pipe 114 in a one-to-one manner. The input end of the circulation water pump 4 is connected to the main pipe of one of the shunt pipes 102, the output end of the circulation water pump 4 is connected to one end of the heat exchange pipe 3, and the other end of the heat exchange pipe 3 is connected to the main pipe of the other shunt pipe 102. The circulation water pump 4 circulates water in the heat exchange pipe 3 and each solar water heating pipe 114, so that the heated water flows into the room, and the heated water dissipates heat in the room, thereby heating the room.

[0044] Combined with the attached Figures 5 to 8As shown, the above-mentioned replacement mechanism includes two synchronous pulleys 125, a synchronous belt 122, and two connecting blocks 123. One end of the axles of the two synchronous pulleys 125 is respectively rotatably installed at the inner top and bottom of one end of the external housing 101. The synchronous belt 122 is sleeved on the two synchronous pulleys 125. At the same end position and on the same side of the two groove plates 115 in each cuboid frame 108, a second rotating shaft 121 is fixed. The two second rotating shafts 121 are centrosymmetric. Second rotating holes are provided on the outer sides of the two connecting blocks 123, and the two second rotating shafts 121 are rotatably installed in the second rotating holes. The outer sides of the two connecting blocks 123 are both fixed on the belt surface of the synchronous belt 122. The two synchronous pulleys 125 rotate synchronously through the synchronous belt 122. The synchronous belt 122 performs belt drive, and the two connecting blocks 123 on the synchronous belt 122 move accordingly. Thus, the two connecting blocks 123 perform relative movement, and the connecting blocks 123 drive the groove plates 115 to move, thereby performing position replacement.

[0045] Combined with the attached Figures 5 to 8 As shown, the above-mentioned driving mechanism includes a synchronous rod 110, multiple first bevel gears 111, and a servo motor 112. The two ends of the synchronous rod 110 are respectively rotatably installed at both ends inside the external housing 101. The synchronous rod 110 is coaxially fixed with the multiple first bevel gears 111. The axles of the multiple synchronous pulleys 125 at the same height are all fixedly provided with second bevel gears 124 coaxially arranged with them. Each first bevel gear 111 is meshed with each second bevel gear 124 one by one. The housing of the servo motor 112 is fixed inside the external housing 101, and the output shaft of the servo motor 112 is coaxially fixed with the axle of one of the synchronous pulleys 125. The servo motor 112 rotates the synchronous pulley 125 fixed to it through the output shaft. This synchronous pulley 125 rotates the second bevel gear 124 installed through the synchronous belt 122. The second bevel gear 124 drives the synchronous rod 110 to rotate through the first bevel gear 111 meshed with it. The first bevel gears 111 on the synchronous rod 110 rotate synchronously, and each first bevel gear 111 drives the synchronous pulleys 125 of the remaining cuboid frames 108 to rotate respectively through the second bevel gears 124 meshed with each other, that is, the synchronous belts 122 rotate synchronously.

[0046] More specifically, a transmission gear 120 coaxial with the second rotating shaft 121 is fixed to one end of the second rotating shaft 121. Two toothed plates 119 are fixed to the inner bottom and top of one end of each rectangular parallelepiped frame 108. The toothed plates 119 at the same height are respectively located on both sides of the synchronous belt 122, and the teeth of the toothed plates 119 face the same direction. The two toothed plates 119 at the bottom and the two toothed plates 119 at the top are centrosymmetric. A first rotating shaft 117 coaxial with the second rotating shaft 121 is fixed to the other end of each groove plate 115. Two guide plates 130 respectively located on both sides of the synchronous belt 122 are fixed inside the other end of the rectangular parallelepiped frame 108. A moving block 116 is slidably sleeved on the outer side of the guide plate 130. A circular groove is formed on the outer side of the moving block 116, and a first rotating hole coaxial with it is formed on the inner side of the circular groove. The first rotating shaft 117 is rotatably installed in the first rotating hole. A torsion spring 118 is arranged in the circular groove, and both ends of the torsion spring 118 are fixed to the outer side of the first rotating shaft 117 and the inner side of the circular groove respectively; when the two groove plates 115 in the same rectangular parallelepiped frame 108 are displaced in position, such as when the top groove plate 115 and the bottom groove plate 115 are displaced in position, the transmission gear 120 on the groove plate 115 is toggled by the toothed plate 119, so that the two groove plates 115 in the same rectangular parallelepiped frame 108 rotate towards both sides respectively, that is, the two groove plates 115 are staggered from each other. When the transmission gear 120 just separates from the toothed plate 119, the groove plate 115 remains in the vertical state. At this time, the torsion spring 118 is in the original state. When the bottom groove plate 115 reaches the top of the rectangular parallelepiped frame 108, the transmission gear 120 of the groove plate 115 is toggled by the bottom toothed plate 119, and the groove plate 115 is toggled to the horizontal state, thus completing the displacement.

[0047] Combined with the attached Figure 2 and Figure 3 One side of the external shell 101 is fixed with an electric louver 103 for adjusting the air volume. The flow guiding assembly includes a flow collecting cover 107, an exhaust duct 104 and an induced draft fan 105. The induced draft fan 105 introduces external air flow into the external shell 101. The flow collecting cover 107 is fixed to the other side of the external shell 101. The air flow entering the external shell 101 converges in the flow collecting cover 107, and the cover opening of the flow collecting cover 107 is communicated with the external shell 101. The outer shell of the induced draft fan 105 is fixedly installed in the cover neck of the flow collecting cover 107. One end of the cover neck of the flow collecting cover 107 is fixed with a flow guiding pipe 2 communicated with it, and the flow guiding pipe 2 guides the air flow into the room.

[0048] Working principle: Combined with the attached Figure 1, in a summer environment, the electric louver 103 is used to adjust the air volume. The induced draft fan 105 introduces the outside air flow into the external housing 101. At this time, in a humid and hot environment, the porous hydrophilic filler 127 will remove the moisture in the air and dry the air. In a hot environment, the moisture of the porous hydrophilic filler 127 evaporates, and the evaporation absorbs heat for refrigeration, thereby cooling the inside of the external housing 101. At the same time, at night or in the early morning when the temperature is low, the porous hydrophilic filler 127 absorbs the morning dew for daytime use, achieving energy conservation; the radiative cooling material 126 further cools the external housing 101. At the same time, when the inside of the external housing 101 is cooled, the cold storage material 129 is cooled for cooling crystallization to store cold energy. When it is difficult to reduce the heat of the external housing 101, the cold storage material 129 crystallizes and melts, absorbs heat, and releases cold energy, thereby further improving energy conservation. At the same time, in the early morning when the temperature is low, the cold storage material 129 is cooled for cooling crystallization for use in a hot environment during the day, releasing cold energy and improving the energy utilization rate; that is, the refrigeration structure 106 cools the inside of the external housing 101. The air flow forms a cold air flow when flowing through the external housing 101, and then the cold air flow is led out of the external housing 101. The cold air flow enters the room to cool the room.When summer turns to winter, the servo motor 112 is started. The servo motor 112 rotates the synchronous pulley 125 fixed to its output shaft. The synchronous pulley 125 rotates the second bevel gear 124 installed through the synchronous belt 122. The second bevel gear 124 drives the synchronous rod 110 to rotate through the first bevel gear 111 meshed with it. Each first bevel gear 111 on the synchronous rod 110 rotates synchronously. Each first bevel gear 111 drives the synchronous pulley 125 of the remaining cuboid frames 108 to rotate respectively through the second bevel gear 124 meshed with each other, that is, each synchronous belt 122 rotates synchronously. When the position replacement of the two groove plates 115 in the same cuboid frame 108 occurs, such as when the top groove plate 115 and the bottom groove plate 115 perform position replacement, the transmission gear 120 on the groove plate 115 is toggled by the toggle plate 119, causing the two groove plates 115 in the same cuboid frame 108 to rotate to both sides respectively, that is, the two groove plates 115 are staggered from each other. When the transmission gear 120 just separates from the toothed plate 119, the groove plate 115 remains in the vertical state. At this time, the coil spring 118 is in the original state. When the bottom groove plate 115 reaches the top of the cuboid frame 108, the transmission gear 120 of the groove plate 115 is toggled by the bottom toothed plate 119, and the groove plate 115 is toggled back to the horizontal state, thus completing the replacement. That is, through the replacement mechanism, the groove plate 115 installed with the heating structure 109 is placed at the top of the external shell 101, and the groove plate 115 installed with the refrigeration structure 106 is placed at the bottom of the external shell 101. The sunlight is refracted by the concave reflector 113 onto the solar water heater pipe 114 and used to heat the water. The circulating water pump 4 makes the water circulate in the heat exchange pipe 3 and each solar water heater pipe 114, so that the heated water flows into the house, and the heated water dissipates heat in the house, thereby heating the house.
