DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figure 1-Figure 7 As shown, this embodiment provides an energy-saving outer window for winter heating of a substation in a high-cold area, comprising a first rolling curtain 1 arranged outside a window 3 and a second rolling curtain 2 arranged outside the window 3, the first rolling curtain 1 and the second rolling curtain 2 being electrically connected to a control module 4 arranged on the window 3; a glass window 5 is embedded in the window 3;

[0032] The first rolling curtain 1 comprises a first rolling box 6 arranged at the top inner side of the window 3, and an energy absorbing curtain 9 is movably connected in the first rolling box 6, and the energy absorbing curtain 9 has a light-heat conversion function;

[0033] The second rolling curtain 2 comprises a second rolling box 8 arranged at the top end of the outer side of the window 3, and a heat insulation curtain 7 is movably connected in the second rolling box 8, and the heat insulation curtain 7 is provided with suction corresponding to the window 3;

[0034] The glass window 5 is filled with a phase change material 10 .

[0035] The present invention discloses an energy-saving exterior window for winter heating of a transformer substation in a high-cold area. The glass window 5 is detachably connected to the window 3 and is filled with a phase change material 10, which is replaceable, and the construction and installation are more convenient, reducing the construction workload. At the same time, the phase change material 10 is arranged to store heat through the phase change of the phase change material 10, which can absorb heat during the day and release heat when the temperature is low at night, thereby increasing the indoor temperature and improving the thermal insulation effect. The first roller blind 1 is arranged on the inner side of the window 3 and is unfolded when the sun is sufficient. Under the premise of not affecting the light, the solar energy is converted into thermal energy, one part of which provides heat for the room, and the other part is absorbed by the phase change material 10, thereby improving the thermal insulation effect. The second roller blind 2 is arranged outside the window 3, has a thermal insulation effect, prevents heat from overflowing, and improves the thermal insulation effect. The heat-insulating curtain 7 is retracted in the second roll box and can be retracted when not needed to prevent affecting the light, while the energy-absorbing curtain 9 can be retracted in the first roll box 6, and retracted when not needed to prevent affecting the function of the window 3. When the light is sufficient, the energy-absorbing curtain 9 is released to convert the solar energy into thermal energy, thereby improving the indoor warming effect. The invention has a simple structure, is easy to construct, requires less modification to the industrial building structure, is not affected by the characteristics of the industrial building itself, has good thermal insulation effect, good uniformity, strong scalability, and is suitable for promotion and use in high-cold areas.

[0036] Further optimization scheme, the bottom end of the energy absorbing curtain 9 is fixedly connected with a first movable magnetic block 11, and the bottom end of the inner side of the window 3 is provided with a first fixed magnetic block 12 corresponding to the first movable magnetic block 11, and the first movable magnetic block 11 and the first fixed magnetic block 12 are arranged by suction. The first movable magnetic block 11 at the bottom end of the energy absorbing curtain 9 can not only serve as a weight at the bottom end to facilitate the unfolding of the energy absorbing curtain 9; at the same time, when it is released, the first movable magnetic block 11 and the first fixed magnetic block 12 can be attracted to fix the energy absorbing curtain 9 to prevent shaking, improve the stability of the energy absorbing curtain 9, and ensure the light-heat conversion effect of the energy absorbing curtain 9.

[0037] Further optimization scheme, the bottom end of the heat insulation curtain 7 is fixedly connected with a second movable magnetic block 13, and the bottom end of the outer side of the window 3 is provided with a second fixed magnetic block 14 corresponding to the second movable magnetic block 13, and the second movable magnetic block 13 and the second fixed magnetic block 14 are arranged by suction. The second movable magnetic block 13 at the bottom end of the heat insulation curtain 7 can not only serve as a weight at the bottom end to facilitate the unfolding of the heat insulation curtain 7; at the same time, when the heat insulation curtain 7 is released, the second movable magnetic block 13 and the second fixed magnetic block 14 are attracted to each other, so as to realize the fixation of the heat insulation curtain 7, improve the stability of the heat insulation curtain 7, prevent the appearance of a gap between the heat insulation and the window 3, ensure the heat insulation effect between the heat insulation curtain 7 and the window 3, and improve the thermal insulation performance of the window 3.

[0038] A further optimized solution is that the first winding box 6 includes a first box body 15, in which a first winding rod 16 is rotatably connected, the top end of the thermal insulation curtain 7 is fixedly connected to the outer wall of the first winding rod 16, and the energy absorbing curtain 9 is wound on the first winding rod 16; the first winding rod 16 is transmission-connected to a first motor 17 arranged on the first winding box 6; the second winding box 8 includes a second box body 18, in which a second winding rod 19 is rotatably connected, the top end of the thermal insulation curtain 7 is fixedly connected to the outer wall of the second winding rod 19, and the thermal insulation curtain 7 is wound on the second winding rod 19; the winding rod is transmission-connected to a second motor 20 arranged on the second winding box 8. Both the energy absorbing curtain 9 and the thermal insulation curtain 7 are flexibly arranged. When not in use, the first motor 17 realizes the retraction and extension of the energy absorbing curtain 9 by rotating the first rolling rod 16, and the second motor 20 realizes the retraction and extension of the thermal insulation curtain 7 by rotating the second rolling rod 19. The energy absorbing curtain 9 and the thermal insulation curtain 7 are respectively rolled up into the first box body 15 and the second box body 18, which can meet the needs when in use or not in use.

[0039] In a further optimized solution, the glass window 5 includes a plurality of insulating glasses 21 arranged side by side, and a plurality of insulating cavities 22 are formed between adjacent insulating glasses 21. The insulating cavities 22 near the outside of the window 3 are evacuated, and the insulating cavities 22 near the inside of the window 3 are filled with phase change materials 10. In this embodiment, the glass window 5 includes three layers of insulating glasses 21, thereby forming two layers of insulating cavities 22, wherein the insulating cavities 22 on the outside are evacuated to improve the effect of heat preservation and heat insulation, and the phase change materials 10 filled in the insulating cavities 22 on the inside can store heat through phase change when there is sufficient sunlight and the temperature is high, and release heat when the temperature is low to improve the heat preservation effect.

[0040] Further optimization scheme, the phase change material 10 includes paraffin and silicon dioxide. In this embodiment, paraffin and silicon dioxide SiO2 can be mixed by physical stirring to form a mixture, silicon dioxide is shaken by an ultrasonic cleaner, and paraffin is injected into the ultrasonic cleaner and shaken together with silicon dioxide for mixing. After cooling, the two phases are not separated, and a low-cost homogeneous phase change material 10 is prepared to improve the synergy between paraffin and other materials. When the mass fraction of SiO2 is set to 5% of paraffin, the phase change temperature is about 18°C, the latent heat value is slightly reduced, the paraffin compounding effect is better, and the appropriate phase change temperature can meet practical applications. The SiO2 eutectic mixture with the best mass ratio is modified by adding 1% of nano silver copper powder, which greatly improves its photothermal performance and improves the utilization rate of light of the phase change material 10. After modification, the heating time is shortened and the latent heat value is reduced less. Nano silver copper powder has good chemical compatibility with paraffin, and the composite phase change material 10 is a physical mixture, and no new substances are produced, and it has good heat storage and release performance. When the mass ratio of modified paraffin wax to nano silver copper powder is 1:100, nano copper silver powder is evenly distributed in the micropores of silica under the action of capillary adsorption, and the composite phase change material 10 basically reaches a saturated adsorption state. Its phase change latent heat and mass loss are small, and it has good thermal cycle stability and its own thermodynamic properties in practical applications.

[0041] Further optimizing the scheme, the energy absorbing curtain 9 includes a plurality of photothermal blocks 23 arranged in an array, and the photothermal blocks 23 include polyethylene glycol, carboxyl cellulose nanofibers and acid-treated carbon fibers. The photothermal blocks 23 use polyethylene glycol as a phase change component, carboxyl cellulose nanofibers as a supporting material, and acid-treated carbon fibers as a light absorber and a heat and electrical conductor to construct a flexible phase change composite film with a light / electric-heat conversion function.

[0042] Further optimizing the scheme, the control module 4 includes a control box 24 arranged on the inner side of the window 3, and the control box 24 is provided with a photosensitive sensor 25 and a temperature sensor 26, and the photosensitive sensor 25 and the temperature sensor 26 are respectively electrically connected to the first motor 17 and the second motor 20. The control module 4 has a photosensitive sensor 25 and a temperature sensor 26, and the light sensor controls whether the inner and outer energy absorption curtains 9 and the heat insulation curtain 7 are rolled up by monitoring the intensity of sunlight. When sunlight appears, the outer heat insulation curtain 7 is rolled up and the inner energy absorption curtain 9 is put down; when sunlight disappears, the outer heat insulation curtain 7 is put down and the inner energy absorption curtain 9 is rolled up.

[0043] Construction steps:

[0044] Prepare the phase change material 10, cut the insulating glass 21 of corresponding size, seal the three sides of the insulating glass 21 with glue, pour the phase change material 10 into the insulating cavity 22 from the upper layer, seal the upper layer, seal the top of the insulating glass 21, and complete the production of the glass window 5;

[0045] The first box body 15 and the second box body 18 are respectively placed inside and outside the window 3 at 20 cm above the inside and outside sides of the window 3, and the control module 4 is installed 15 cm on the left or right side of the indoor window 3, connected to the first motor 17 and the second motor 20; when the light sensor senses that the illumination exceeds 500 lux, the signal is transmitted to the control module 4, the first motor 17 is started, and the energy absorbing curtain 9 rotates down, thereby receiving light and releasing heat, a part of the heat is provided to the indoor heating of the substation, and the other part is absorbed by the phase change material 10 and used when the temperature drops. On the contrary, when the illumination is lower than 500 lux, the energy absorbing curtain 9 rotates up and the heat insulation curtain 7 rotates down.

[0046] This device can automatically control the indoor temperature, providing feasibility for winter heating of substations in high-cold areas and further promoting the development of zero-carbon substations.
