Description

Technical Field

[0001] The invention belongs to the technical field of glass curtain walls, in particular to a constant temperature circulating water building glass curtain wall with adjustable shading degree. Background Art

[0002] Modern architecture is gradually moving towards intelligence, energy conservation and sustainable development. As an important component of the exterior wall, building curtain walls are both aesthetically pleasing and functional, and are a key area of ​​architectural technology research. Although traditional curtain walls play an important role in heat insulation and shading, their functions are single and it is difficult to meet diverse needs.

[0003] Traditional curtain wall design is mainly based on fixed structure. Its heat insulation and shading performance are determined in the design stage. It is impossible to adjust the shading effect according to the angle and intensity of sunlight. Due to the high light transmittance of glass, the heat load in the building is high. Simply relying on the heat insulation performance of glass materials is often difficult to meet the building requirements. For this reason, we proposed a constant temperature circulating water architectural glass curtain wall with adjustable shading. Summary of the invention

[0004] In order to solve the problem raised in the background technology, the present invention provides the following technical solution: a constant temperature circulating water architectural glass curtain wall with adjustable shading, comprising a glass curtain wall, a shading adjustment cavity and a constant temperature circulating water cavity are provided on the glass curtain wall, a partition wall is provided between the shading adjustment cavity and the constant temperature circulating water cavity,

[0005] The shading degree adjustment chamber includes a rotating shaft, which is arranged on the inner wall of the shading degree adjustment chamber, and a louver is rotatably arranged on the rotating shaft. Two transmission chambers are provided on the glass curtain wall, and the two transmission chambers are symmetrically arranged on both sides of the shading degree adjustment chamber. A connecting channel is provided between the shading degree adjustment chamber and the transmission chamber. A main shaft is provided on the transmission chamber, and a connecting ring is provided on the main shaft. The connecting ring is connected to the end of the louver through a connecting rod. A guide rod is provided on the louver, and a collar is provided at one end of the connecting rod. The collar can be slidably sleeved on the guide rod, and a limiting protrusion is provided at one end of the guide rod. The connecting rod passes through the connecting channel, and a motor is provided on the main shaft.

[0006] The constant temperature circulating water chamber includes a water circulation pipeline, a heat exchanger is arranged on the water circulation pipeline, the water circulation pipeline is respectively connected to the refrigerant inlet and outlet of the heat exchanger, a plunger pump and an auxiliary pump are arranged on the water circulation pipeline, the plunger pump has a piston, and the piston is connected to the main shaft through a linkage mechanism.

[0007] Preferably, the linkage mechanism includes a first gear, which is sleeved on a main shaft on one side, and a second gear is arranged on the constant temperature circulating water chamber. The second gear is connected to the first gear through a belt drive, and a transmission shaft is arranged on the second gear. The transmission shaft can be rotatably passed through the top wall of the glass curtain wall and inserted into the constant temperature circulating water chamber. A cam is arranged at the other end of the transmission shaft, and a connecting rod is arranged at the bottom of the cam, and the connecting rod is connected to the piston. Through this linkage mechanism, synchronous adjustment of shading degree and water flow rate can be achieved to adapt to different temperature control and shading requirements.

[0008] Preferably, a heat recovery device is provided on the shading adjustment cavity, and the heat recovery device includes a photovoltaic panel. The photovoltaic panel is provided on the louver and can capture solar energy as the louver rotates. A conductive cable is provided on the louver, and the output end of the cable passes through the top wall of the shading adjustment cavity and is connected to the input end of the charging controller. The output end of the charging controller is connected to a storage battery. The photovoltaic panel recovers solar energy and converts it into electrical energy, which can not only increase the energy self-sufficiency of the system, but also reduce dependence on external energy, thereby improving the sustainability of the system.

[0009] Preferably, there are multiple rotating axes, all of which are parallel to the ground and vertically distributed along the height direction of the glass curtain wall. The multiple rotating axes are arranged equidistantly, and the louvers can more evenly adjust the shading effect of each position, ensuring uniform shading effect of the entire curtain wall and optimizing light control.

[0010] Preferably, a plurality of the photovoltaic panels are arranged on a plurality of louvers, and the plurality of photovoltaic panels are connected in series through cables to form a power supply mechanism, and the charging controller, energy storage battery and power supply mechanism are connected in series to provide sufficient energy for the operation of the system.

[0011] Preferably, the main shaft has a threaded portion, and the connecting ring is provided with a threaded groove, the threaded groove matches the threaded portion, and the rotation of the main shaft drives the connecting ring to move up and down, thereby accurately controlling the angle change of the louver blades, which helps to improve the control accuracy and ensure more precise shading adjustment.

[0012] Preferably, when the rotation angle of the louver increases, the shading effect weakens, and the rotation angle of the main shaft increases accordingly. The transmission shaft drives the piston through the cam to increase the extension amount, thereby increasing the water flow rate. The increase in the louver angle means that the shading effect weakens, which may cause the indoor temperature to rise. Therefore, it is necessary to increase the water flow rate to enhance heat exchange and keep the indoor temperature stable.

[0013] Preferably, the louver blades have an adjustment angle of 0°-50°, and the louver blades are flat, and the light intensity is adjusted according to demand. The flat design is conducive to maximizing the adjustment of light and reducing air resistance.

[0014] Preferably, the transmission ratio between the main shaft and the transmission shaft is 1:2-1:3, and the piston expansion and contraction amount is 1-2mm when the main shaft rotates one circle. The setting of the transmission ratio and the piston expansion and contraction amount ensures the precise match between the rotation of the main shaft and the expansion and contraction of the piston, which helps to regulate the water flow and heat exchange, so that the temperature control and shading effects remain consistent.

[0015] Preferably, the glass curtain wall is made of tempered glass, and the surface of the glass curtain wall is coated with an anti-UV coating, which is made of titanium dioxide or fluoride, which helps to improve the strength and impact resistance of the glass, enhance the safety of the building, and reduce the impact of ultraviolet rays on the interior of the building.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the outdoor light intensity changes, the manual control motor drives the main shaft to rotate, driving the connecting ring to move up and down. The connecting ring transmits movement through the connecting rod. The sleeve ring ensures the stability of the connection between the connecting rod and the guide rod. The connecting rod moves up and down. When the connecting rod moves up, one end is slidably connected to the guide rod, which can lift the louver upward, thereby causing the louver to flip upward around the rotating axis, changing the angle of the louver, thereby adjusting the shading degree. The limit block serves as a physical restriction to ensure that the sleeve ring will not over-stretch or move uncontrollably when sliding on the guide rod. The water flowing in the water circulation pipe exchanges heat with the glass curtain wall. The heat exchanger exchanges heat with water through the refrigerant to play a role in temperature control. The plunger pump is responsible for adjusting the water flow rate. The piston on it is connected to the main shaft through a linkage mechanism. As the main shaft rotates, the first gear and the second gear The wheels are connected through a belt drive, and the drive shaft drives the cam to rotate, which in turn pushes the piston to extend and retract through the connecting rod, thereby adjusting the water flow of the plunger pump. When the angle of the louver increases and the shading effect weakens, the flow of the plunger pump increases, ensuring that the heat exchange efficiency is improved and the temperature is effectively controlled. Conversely, when the angle of the louver decreases, the water flow will decrease, thereby reducing heat exchange and ensuring the synchronous adjustment between the louver angle and the water flow. During operation, the plunger pump and the auxiliary pump work together to maintain the stability and reliability of the water flow. The photovoltaic panel captures solar energy through the change in the angle of the louver, converts light energy into electrical energy, and transmits it to the charging controller through a conductive cable, and then stores it in the energy storage battery. It can adjust the shading effect according to the angle and intensity of sunlight and indoor needs, reducing dependence on changes in external ambient temperature. BRIEF DESCRIPTION OF THE DRAWINGS

A connecting channel is provided between the shading degree adjustment chamber and the transmission chamber 5. A main shaft 6 is provided on the transmission chamber 5. A connecting ring 7 is provided on the main shaft 6. The connecting ring 7 is connected to the end of the shutter blade 4 through a connecting rod 8. A guide rod 401 is provided on the shutter blade 4. A collar 801 is provided at one end of the connecting rod 8. The collar 801 can be slidably sleeved on the guide rod 401. A limiting protrusion 402 is provided at one end of the guide rod 401. The connecting rod 8 passes through the connecting channel. A motor 9 is provided on the main shaft 6.

[0028] The constant temperature circulating water chamber includes a water circulation pipeline 10, on which a heat exchanger 11 is arranged. The water circulation pipeline 10 is respectively connected to the refrigerant inlet and outlet of the heat exchanger 11. A plunger pump 12 and an auxiliary pump 24 are arranged on the water circulation pipeline 10. The plunger pump 12 has a piston 13, and the piston 13 is connected to the main shaft 6 through a linkage mechanism.

[0029] The linkage mechanism includes a first gear 14, which is sleeved on a main shaft 6 on one side. A second gear 15 is arranged on the constant temperature circulating water chamber. The second gear 15 is connected to the first gear 14 through a belt 16. A transmission shaft 17 is arranged on the second gear 15. The transmission shaft 17 can be rotatably inserted into the constant temperature circulating water chamber through the top wall of the glass curtain wall 1. A cam 18 is arranged at the other end of the transmission shaft 17. A connecting rod 19 is arranged at the bottom of the cam 18. The connecting rod 19 is connected to the piston 13. Through this linkage mechanism, the shading degree and the water flow rate can be synchronously adjusted to meet different temperature control and shading requirements.

[0030] A heat recovery device is provided on the shading adjustment cavity, and the heat recovery device includes a photovoltaic panel 20. The photovoltaic panel 20 is provided on the louver 4 and can capture solar energy as the louver 4 rotates. A conductive cable 21 is provided on the louver 4. The output end of the cable 21 passes through the top wall of the shading adjustment cavity and is connected to the input end of the charging controller 22. The output end of the charging controller 22 is connected to the energy storage battery 23. The photovoltaic panel 4 recovers solar energy and converts it into electrical energy, which can not only increase the energy self-sufficiency of the system, but also reduce the dependence on external energy and improve the sustainability of the system.

[0031] There are multiple rotating axes 3, which are all parallel to the ground and vertically distributed along the height direction of the glass curtain wall 1. The multiple rotating axes 3 are arranged equidistantly. The louvers 4 can more evenly adjust the shading effect of each position to ensure uniform shading effect of the entire curtain wall and optimize light control.

[0032] A plurality of photovoltaic panels 20 are arranged on a plurality of louvers 4, and the plurality of photovoltaic panels 20 are connected in series via cables 21 to form a power supply mechanism. A charging controller 22, an energy storage battery 23, and the power supply mechanism are connected in series to provide sufficient energy for the operation of the system.

[0033] The main shaft 6 has a threaded portion, and the connecting ring 7 has a threaded groove, which matches the threaded portion. The rotation of the main shaft 6 drives the connecting ring 7 to move up and down, thereby accurately controlling the angle change of the louver 4, which helps to improve the control accuracy and ensure more accurate shading adjustment.

[0034] When the rotation angle of the louver 4 increases, the shading effect weakens, and the rotation angle of the main shaft 6 increases accordingly. The transmission shaft 17 drives the piston 13 to increase the extension amount through the cam 18, thereby increasing the water flow rate. The increase in the angle of the louver 4 means that the shading effect is weakened, which may cause the indoor temperature to rise. Therefore, it is necessary to increase the water flow rate to enhance heat exchange and keep the indoor temperature stable.

[0035] The louver 4 has an adjustment angle of 0°-50°, and the louver 4 is flat, and the light intensity is adjusted according to demand. The flat design is conducive to maximizing the light adjustment and reducing air resistance.

[0036] The transmission ratio between the main shaft 6 and the transmission shaft 17 is 1:2-1:3, and the piston 13 expands and contracts by 1-2 mm when the main shaft 6 rotates one circle. The setting of the transmission ratio and the expansion and contraction of the piston ensures the precise match between the rotation of the main shaft 6 and the expansion and contraction of the piston 13, which helps to adjust the water flow and heat exchange, so that the temperature control and shading effects remain consistent.

[0037] The glass curtain wall 1 is made of tempered glass, and the surface of the glass curtain wall 1 is coated with an anti-ultraviolet coating, which is made of titanium dioxide or fluoride, which helps to improve the strength and impact resistance of the glass, enhance the safety of the building, and reduce the impact of ultraviolet rays on the interior of the building.

[0038] Working principle: when the outdoor light intensity changes, the manual control motor 9 drives the main shaft 6 to rotate, driving the connecting ring 7 to move up and down. The connecting ring 7 transmits movement through the connecting rod 8. The collar 801 ensures that the connection between the connecting rod 8 and the guide rod 401 is stable, and the connecting rod 8 moves up and down. When the connecting rod 8 moves up, one end is slidably connected to the guide rod 401, which can push up the louver 4, and then make the louver 4 flip upward around the rotating axis 3, change the angle of the louver 4, and thus adjust the shading degree. The limiting protrusion 402 serves as a physical restriction to ensure that the collar 801 will not be over-stretched or moved uncontrollably when sliding on the guide rod 401. The water flowing in the water circulation pipe 10 exchanges heat with the glass curtain wall 1. The heat exchanger 11 exchanges heat with water through the refrigerant to play a role in temperature control. The plunger pump 12 is responsible for adjusting the water flow rate. The piston 13 thereon is connected to the main shaft 6 through a linkage mechanism. As the main shaft 6 rotates, the first The gear 14 and the second gear 15 are connected through the belt 16 transmission, and the transmission shaft 17 drives the cam 18 to rotate, and then pushes the piston 13 to retract and retract through the connecting rod 19, so as to adjust the water flow of the plunger pump 12. When the angle of the louver 4 increases and the shading effect weakens, the flow of the plunger pump 12 increases, ensuring that the heat exchange efficiency is improved and the temperature is effectively controlled. On the contrary, when the angle of the louver 4 decreases, the water flow will decrease, thereby reducing the heat exchange and ensuring the synchronous adjustment between the angle of the louver 4 and the water flow. During operation, the plunger pump 12 and the auxiliary pump 24 work together to maintain the stability and reliability of the water flow. The photovoltaic panel 20 captures solar energy through the angle change of the louver 4, converts the light energy into electrical energy, and transmits it to the charging controller 22 through the conductive cable 21, and then stores it in the energy storage battery 23. It can adjust the shading effect according to the sunlight angle, intensity and indoor demand, reducing the dependence on the external ambient temperature change.
