Description

Technical Field

[0001] The present invention belongs to the technical field of energy-saving buildings, and particularly relates to an energy-saving building heat-insulating wall and a heat-insulating method. Background Art

[0002] When there is a large temperature difference between the inside and outside of a building, obvious heat transfer phenomena will occur. Affected by the heat conduction medium, the heat transfer on the ground is faster than that in the air. In order to keep the indoor temperature constant, when heating the interior of the building, the energy consumption required increases significantly.

[0003] For this reason, a Chinese utility model patent with the authorization announcement number CN212926522U discloses an energy-saving device for preventing the lateral heat transfer of the ground of a building, including a wall. An outer wall insulation layer is arranged on the left side of the wall, a ground surface insulation layer is arranged at the bottom on the left side of the outer wall insulation layer, an underground insulation layer is arranged at the bottom on the left side of the ground surface insulation layer, an inner wall insulation layer is arranged on the right side of the wall, a floor is arranged at the bottom on the right side of the wall, and the number of the floors is two. By the cooperation of the underground insulation layer and the ground surface insulation layer, the sealing performance is good and heat bridges are avoided, effectively preventing the lateral heat transfer of the ground of the building. Through the cooperation of the outer wall insulation layer and the inner wall insulation layer, the heat on the ground can be effectively blocked from conducting to the outside, thereby reducing the heat flow between the inside and the outside. This energy-saving device conducts heat insulation treatment by arranging insulation layers on the wall and underground to prevent heat transfer. However, this method will affect the normal heat dissipation of the building. In summer, the indoor is relatively stuffy. Under the same external air temperature, the indoor temperature will be higher than before, and air conditioning needs to be turned on for refrigeration, thus affecting the energy-saving effect.

Specific embodiments

[0029] To clearly illustrate the technical features of this solution, the following describes this solution through specific embodiments and in conjunction with its accompanying drawings.

[0030] As Figure 1 and Figure 2 shown, an energy-saving building heat insulation wall includes a frame 1, a lifting control device 2, and a telescopic control device 3. The frame 1 is buried underground. An outer bracket 11 and an inner bracket 12 are installed on the frame 1. A heat insulation wall 13 for preventing heat transfer and a heat conduction frame 14 for guiding heat transfer are movably arranged on the frame 1. The heat conduction frame 14 is preferably made of corrosion-resistant materials such as metal or ceramic; the heat insulation wall 13 is located between the outer bracket 11 and the inner bracket 12. The lifting control device 2 is arranged on the frame 1 and is used to control the lifting of the heat insulation wall 13. The telescopic control device 3 is arranged on the frame 1 and is used to control the telescopic movement of the heat conduction frame 14. The present invention realizes the function of flexibly switching between two states of heat insulation and heat conduction through the frame 1, the lifting control device 2, and the telescopic control device 3, and can control the heat transfer speed according to needs, thereby achieving the effect of energy conservation and emission reduction, and solving the problem that traditional heat insulation devices can only prevent heat transfer and cannot actively dissipate or absorb heat.

[0031] When heat insulation is required, the operator controls the heat-conducting frame 14 to retract to the inner support 12 through the telescopic control device 3, and drives the heat-insulating wall 13 to descend from above the ground to below the ground through the lifting control device 2, and prevents the heat transfer through the heat-insulating wall 13, thereby playing a role in heat preservation. When active control of heat transfer is required, the operator drives the heat-insulating wall 13 to rise from below the ground to above the ground through the lifting control device 2, and controls the heat-conducting frame 14 to connect the outer support 11 and the inner support 12 through the telescopic control device 3, and increases the heat transfer speed through the heat-conducting frame 14.

[0032] like Figure 1 , Figure 3 and Figure 6 As shown, the lifting control device 2 includes a lifting assembly 21 for driving the heat insulation wall 13 to lift and lower, and the lifting assembly 21 is electrically connected to the controller. The telescopic control device 3 includes a telescopic driving assembly 31, a transmission assembly 32, a pushing assembly 33 and a nitrogen spring 34. The telescopic driving assembly 31 includes a rack 311, a first screw 312 and a rotating gear 313. The rack 311 is slidably mounted on the frame 1 and connected to the piston rod of the nitrogen spring 34; the first screw 312 is rotatably mounted on the frame 1 and is threadedly connected to the heat conduction frame 14; the rotating gear 313 is rotatably mounted on the frame 1 and is meshed with the rack 311. When the rotating gear 313 rotates, the first screw 312 is driven to rotate synchronously through the transmission assembly 32. The transmission assembly 32 is arranged on the frame 1, the pushing assembly 33 is arranged on the heat insulation wall 13, and the nitrogen spring 34 is arranged on the frame 1. When the lifting assembly 21 controls the heat insulation wall 13 to descend, the heat insulation wall 13 pushes the rack 311 downward by overcoming the elastic force of the nitrogen spring 34 through the pushing assembly 33, and the rack 311 drives the rotating gear 313 to rotate.

[0033] The heat-conducting frame 14 and the heat-insulating wall 13 are controlled by the lifting assembly 21, the telescopic driving assembly 31, the transmission assembly 32, the pushing assembly 33 and the nitrogen spring 34. When the heat-insulating wall 13 moves downward, the heat-conducting frame 14 is automatically controlled to be recovered. A limit ring 3121 for limiting the moving range of the heat-conducting frame 14 is provided at one end of the first screw rod 312 away from the frame 1.

[0034] like Figure 1 , Figure 3 and Figure 6 As shown, the transmission assembly 32 includes a first rotating shaft 321, a first pulley 322 and a first synchronous belt 323. The first rotating shaft 321 is rotatably mounted on the frame 1, and the rotating gear 313 is fixedly mounted on the first rotating shaft 321; two first pulleys 322 are provided, and the two first pulleys 322 are respectively fixedly mounted on the first rotating shaft 321 and the first screw rod 312; the two first pulleys 322 are connected by the first synchronous belt 323.

[0035] The connection and rotation of the rotary gear 313 and the first screw 312 are realized through the first rotating shaft 321, the first pulley 322 and the first synchronous belt 323. Since the heat insulation walls 13 of the heat insulation device usually need to be arranged on four sides and distributed in four directions of the building to ensure the heat insulation effect. When heat insulation is required, the operator first sends a signal to the lifting assembly 21 through the controller. After receiving the signal, the lifting assembly 21 drives the heat insulation wall 13 to move downward. The heat insulation wall 13 drives the pushing assembly 33 to move. After the pushing assembly 33 contacts the rack 311, it overcomes the elastic force of the nitrogen spring 34 and pushes the rack 311 downward. The rack 311 drives the rotary gear 313 meshed with it to rotate. The rotary gear 313 drives the first rotating shaft 321 to rotate. The first rotating shaft 321 drives the first screw 312 to rotate through the first pulley 322 and the first synchronous belt 323. When the first screw 312 rotates, the heat conduction frame 14 moves along it, so that the heat conduction frame 14 shrinks to the inner bracket 12. At this time, the heat insulation wall 13 blocks the heat transfer and plays a role in heat preservation.

[0036] As Figures 3 - 5 shown, the pushing assembly 33 includes a fixed push plate 331 and a movable push plate 332. The total downward travel of the heat insulation wall 13 is divided into a first travel and a second travel. Two heat conduction frames 14 and two sets of telescopic drive assemblies 31 are arranged on the same side of the frame 1. The two sets of telescopic drive assemblies 31 are distributed vertically up and down. The fixed push plate 331 is fixedly installed on the heat insulation wall 13. The movable push plate 332 is slidably installed on the heat insulation wall 13. An auxiliary control device 4 for controlling the sliding of the movable push plate 332 is arranged on the heat insulation wall 13. In the working state, the lifting assembly 21 drives the heat insulation wall 13 to move downward for the first travel. The movable push plate 332 contacts the upper rack 311 and pushes the rack 311. After the upper rack 311 is completely pressed, the auxiliary control device 4 controls the movable push plate 332 to be connected to the frame 1. When the heat insulation wall 13 moves downward for the second travel, the movable push plate 332 slides relative to the heat insulation wall 13, and the fixed push plate 331 pushes the lower rack 311 to move.

[0037] The separate driving of the two heat conduction frames 14 can be realized by the fixed push plate 331 and the movable push plate 332, so as to realize the flexible control of the heat insulation wall 13 and the two heat conduction frames 14. The whole frame 1 is arranged underground. Therefore, when heat preservation is carried out, the upper half of the heat insulation wall 13 is close to the ground surface. In some environments with sudden temperature changes, the temperature difference between the ground surface temperature and the underground temperature is relatively large. For this reason, two heat conduction frames 14 and two sets of telescopic driving components 31 are set. When heat insulation or heat conduction control is carried out, the downward movement depth of the heat insulation wall 13 can be controlled according to the demand, and the telescopic of the two heat conduction frames 14 can be automatically controlled according to the downward movement depth of the heat insulation wall 13. When the temperature is relatively high, the ground surface is irradiated by sunlight and the temperature is relatively high, while the underground temperature is relatively low. At this time, the lifting component 21 can be used to control the heat insulation wall 13 to move downward in the first stroke. During the downward movement of the heat insulation wall 13 in the first stroke, the auxiliary control device 4 controls the movable push plate 332 to be connected with the heat insulation wall 13. At this time, the movable push plate 332 cannot move. Therefore, as the heat insulation wall 13 moves downward, the movable push plate 332 will push the rack 311 to move, and then control the upper heat conduction frame 14 to contract into the inner layer support 12; at this time, the lower heat conduction frame 14 is still in the extended state, quickly transferring the heat in the building to the lower-temperature underground, and at the same time avoiding the high temperature on the ground surface from being transferred into the building through the heat insulation wall 13, so as to complete the adjustment of the building temperature without consuming too much energy.

[0038] Such as Figures 3 - 5 , Figures 7 - 9 : The auxiliary control device 4 includes a locking component 41 and a control component 42. The locking component 41 includes a clamping seat 411, a guide rail 412 and an elastic member 413. The clamping seat 411 is slidably installed on the movable push plate 332, and a first clamping groove 4121 matching with the clamping seat 411 is formed on the guide rail 412. The guide rail 412 is installed on the heat insulation wall 13, and the movable push plate 332 is slidably installed on the guide rail 412; both ends of the elastic member 413 are respectively connected with the movable push plate 332 and the clamping seat 411; the control component 42 is arranged on the frame 1 and is used to control the connection between the clamping seat 411 and the frame 1.

[0039] The connection between the movable push plate 332 and the heat insulation wall 13 is controlled by the clamping seat 411, the guide rail 412, the elastic member 413 and the control assembly 42. When the heat insulation wall 13 moves in the first stroke, the clamping seat 411 is snapped into the first card slot 4121 under the elastic force of the elastic member 413, thereby restricting the movement of the movable push plate 332 and preventing it from sliding along the guide rail 412. When the movement in the first stroke is completed, the control assembly 42 overcomes the elastic force of the elastic member 413 to control the clamping seat 411 to move away from the first card slot 4121, so that the clamping seat 411 is separated from the first card slot 4121. At this time, the movable push plate 332 can slide freely along the guide rail 412. At the same time, the control assembly 42 controls the clamping seat 411 to be connected to the frame 1, thereby fixing the clamping seat 411 and the movable push plate 332 and preventing the movable push plate 332 from resetting under the elastic force of the nitrogen spring 34.

[0040] As Figure 4 , Figure 5 , Figures 7 - 9 shown, the control assembly 42 includes a clamping plate 421, an inclined convex block 422 and a linear driver 423. The clamping plate 421 is installed on the frame 1, and a second card slot 4211 that cooperates with the inclined convex block 422 is provided on the clamping plate 421; the inclined convex block 422 is installed on the clamping seat 411; the linear driver 423 is installed on the guide rail 412 and is used to push the clamping seat 411 to move. The linear driver 423 is electrically connected to the controller. The linear driver 423 is preferably a linear cylinder or a linear motor. A push block for pushing the clamping seat 411 is fixedly connected to the driving end of the linear driver 423. The linear driver 423 can stably push the clamping seat 411 through the push block.

[0041] The present invention controls the connection between the clamping seat 411 and the frame 1 through the clamping plate 421, the inclined convex block 422 and the linear driver 423. Specifically, during the movement of the heat insulation wall 13 in the first stage of travel, the clamping plate 421 contacts and presses the inclined convex block 422, and the inclined convex block 422 drives the clamping seat 411 to move away from the first clamping groove 4121 against the elastic force of the elastic member 413, so that the clamping seat 411 is separated from the first clamping groove 4121. When the second clamping groove 4211 on the clamping plate 421 is aligned with the inclined convex block 422, the elastic member 413 resets and pushes the inclined convex block 422 to be clamped with the second clamping groove 4211, thereby indirectly connecting the clamping seat 411 and the frame 1, fixing the clamping seat 411 and the movable push plate 332, and preventing the movable push plate 332 from resetting under the elastic force of the nitrogen spring 34. When driving the heat insulation wall 13 to move upward along the first stroke, a signal is sent to the linear driver 423 through the controller. After receiving the signal, the linear driver 423 drives the clamping seat 411 to move away from the clamping plate 421. At this time, the elastic member 413 is in a compressed state, so that the inclined convex block 422 is separated from the second clamping groove 4211, and then the linear driver 423 resets, and the clamping seat 411 is clamped into the first clamping groove 4121 under the reset elastic force of the elastic member 413.

[0042] As Figure 8 and Figure 9 shown, an extension block 4111 is provided on the clamping seat 411; a guiding groove 4122 is formed in the first clamping groove 4121 of the guide rail 412; when the extension block 4111 and the guiding groove 4122 are aligned in the vertical direction, the movable push plate 332 can slide along the guide rail 412.

[0043] As Figure 1 、 Figure 2 、 Figures 8 - 11 shown, the lifting assembly 21 includes an extension bracket 211, a second screw 212, a rotary driver 213 and a bevel gear 214. The extension bracket 211 is located on the ground and is used to support the heat insulation wall 13 when the heat insulation wall 13 rises. The extension bracket 211 is connected to the frame 1 and is located above the frame 1; the second screw 212 is rotatably installed on the extension bracket 211 and is threadedly connected to the heat insulation wall 13; the rotary driver 213 is installed on the extension bracket 211; the rotary driver 213 is a servo motor, and the servo motor is electrically connected to the controller; there are two bevel gears 214, and the two bevel gears 214 are respectively fixedly sleeved on the driving end of the rotary driver 213 and the second screw 212, and the two bevel gears 214 are meshed and connected.

[0044] When controlling the lifting of the heat insulation wall 13, the operator sends a signal to the rotary drive 213 through the controller. After receiving the signal, the rotary drive 213 drives the second screw 212 to rotate through the bevel gear 214. The second screw 212 drives the heat insulation wall 13 connected to it by threads to lift or lower, thereby realizing the lifting and lowering of the heat insulation wall 13.

[0045] As Figure 1 , Figure 2 , Figures 8 - 11 shown, a synchronization component 22 is further provided on the extension bracket 211. The frame 1 has four sides, and heat insulation walls 13 are provided on all four sides. The synchronization component 22 includes a second rotating shaft 221, a second pulley 222, a second synchronous belt 223, a third pulley 224, and a third synchronous belt 225; the second rotating shaft 221 is rotatably installed on the extension bracket 211; two second pulleys 222 are set as a group, and two third pulleys 224 are set as a group; the two second pulleys 222 in the same group are respectively sleeved on the second rotating shaft 221 and the second screw 212 on the same side of the frame 1; the second synchronous belt 223 connects the two third pulleys 224 in the same group; the two third pulleys 224 are respectively sleeved on the second rotating shaft 221 and the second screw 212 on the adjacent sides of the frame 1; the third synchronous belt 225 connects the two second pulleys 222 in the same group. Through the connection of the second synchronous belt 223 and the third synchronous belt 225, the effect of driving the four-sided heat insulation walls 13 to lift and lower synchronously by one rotary drive 213 is achieved, which not only saves costs but also improves the accuracy of the synchronous lifting of the heat insulation walls 13.

[0046] As Figure 10 and Figure 11 shown, an anti-theft grille 2111 is provided on the extension bracket 211. Anti-theft is carried out through the anti-theft grille 2111, which improves the safety of the building, so that the extension bracket 211 can not only support the heat insulation wall 13 but also play the role of a security fence.
