Description

Technical Field

[0001] This invention relates to a ceiling system, and more particularly to an intelligent ceiling system for prefabricated green building construction applied in the field of building wall panels. Background Technology

[0002] Ceiling systems are functional decorative structures on the interior ceiling of buildings, integrating functions such as concealed piping, lighting layout, and space partitioning. In prefabricated green buildings, one of their core design goals is to reduce energy consumption through optimized space organization. However, traditional ceiling systems have two major problems: First, ceiling panels are usually installed at a high position, requiring the entire space below the ceiling to be heated when the air conditioning is adjusted, while the actual area where people are active only occupies a small portion of that space, resulting in a large volume of air that is not effectively heated. Second, if the air conditioning power is not matched with the indoor space, the system is prone to long-term high-load operation due to insufficient heat exchange efficiency, or frequent start-stop due to temperature fluctuations, further aggravating energy consumption.

[0003] The existing patent application with publication number CN110158836A discloses a height-adjustable ceiling system. By driving the drive components fixed to the house through a control device, the keel and panel are raised and lowered to adjust the thickness of the insulation layer. Combined with the sealing part, the sealing between the panel and the wall is ensured, so as to achieve the function of dynamically controlling the sun protection and heat preservation performance.

[0004] The aforementioned prior art discloses adjustable-height ceilings and sealing parts, but it does not solve the problem of large volume of ineffective heat exchange air and high energy consumption during temperature regulation. Summary of the Invention

[0005] The technical problem that this invention aims to solve in view of the above-mentioned prior art is...

[0006] To address the aforementioned issues, this invention provides an intelligent ceiling system for prefabricated green building construction, comprising a ceiling panel, a lifting mechanism fixedly connected to the ceiling at the upper center of the ceiling panel, a sealing ring fixedly connected to the outer side of the ceiling panel, an annular gap for airflow formed between the sealing ring and the interior wall, a hollow cavity within the sealing ring, a filling pipe fixedly connected to the upper end of the sealing ring, a storage tank fixedly connected to the ceiling, a filling medium filling the storage tank, a pressing plate slidably connected within the storage tank, and an electric push rod fixedly connected to the pressing plate. An exhaust channel is provided on the ceiling panel, which is connected to the cavity below the ceiling panel. The exhaust channel is connected to an air injection pipe that is fixedly connected to the upper part of the ceiling panel. The end of the air injection pipe away from the ceiling panel is fixedly connected to a duct air conditioner. The duct air conditioner is fixedly connected to the ceiling. An infrared distance sensor is fixedly connected to the lower end of the ceiling panel. The lifting mechanism, electric push rod, infrared distance sensor and duct air conditioner are all electrically connected to the same controller. The controller is fixedly connected to the interior wall.

[0007] In the aforementioned intelligent ceiling system for prefabricated green building construction, energy consumption is reduced through expandable sealing rings and exhaust channels opened inside the ceiling panel.

[0008] As a further improvement of this application, a pressure sensor is fixedly connected to the upper surface of the extrusion plate. The pressure sensor is electrically connected to the controller, which includes an alarm module. The input terminal of the alarm module is connected to the pressure sensor.

[0009] As a further improvement of this application, the exhaust channel includes a horizontal channel opened on the upper part of the ceiling panel, the horizontal channel is connected to a vertical channel through a vertical channel, there are multiple vertical channels and the multiple vertical channels are arranged in parallel and equidistantly, the vertical channels are connected to multiple nozzles, and the nozzles extend to the lower end face of the ceiling panel.

[0010] As a further improvement of this application, a solenoid valve is fixedly connected in the vertical channel, and a millimeter-wave radar is fixed on the lower end face of the ceiling panel. Both the solenoid valve and the millimeter-wave radar are electrically connected to the controller.

[0011] As a further improvement of this application, the lifting mechanism is one of a hydraulic cylinder and a winch. The air injection pipe includes a fixed pipe that is fixedly connected to the air outlet of the air duct machine. A sliding pipe is slidably connected inside the fixed pipe. The sliding pipe is fixedly connected to the ceiling panel and connected to the exhaust channel.

[0012] As a further improvement of this application, the sealing ring is made of rubber material, the ceiling board is one of fiber cement board and extruded polystyrene board, the filling medium is one of air and hydraulic oil, and the volume of the storage tank is larger than that of the hollow cavity.

[0013] As a further improvement of this application, the sealing ring has a rectangular frame structure, the hollow cavity is an annular cavity, and multiple vertically equidistant protrusions are fixedly connected to the outer wall of the sealing ring.

[0014] As a further improvement of this application, the outer side of the lifting mechanism is provided with a plurality of damping cylinders evenly distributed. The damping cylinder includes an outer cylinder fixedly connected to the ceiling. A sliding rod is slidably connected inside the outer cylinder. The sliding rod extends to the bottom of the outer cylinder and is fixedly connected to the ceiling panel. A sliding disc is fixedly connected to the upper end of the sliding rod and slidably connected to the inner wall of the outer cylinder. The sliding disc is provided with evenly distributed flow holes. The outer cylinder is filled with hydraulic oil.

[0015] As a further improvement to this application, the following steps are included in its use: Step 1: Start the lifting mechanism via the controller. The lifting mechanism will move the ceiling panel and sealing ring downwards. At the same time, the infrared distance sensor will detect the height of the ceiling panel from the ground in real time. The lifting mechanism will be turned off when the ceiling panel reaches the set height. Step 2: The controller starts the electric push rod, which drives the extrusion plate to move upward in the storage tank. The extrusion plate injects the filling medium in the storage tank into the hollow cavity of the sealing ring through the filling pipe. After the sealing ring expands, it abuts against the indoor wall. The expanded sealing ring and the ceiling panel divide the indoor space into two independent spaces, upper and lower. Step 3: The controller starts the duct air conditioner. The duct air conditioner injects hot and cold air into the exhaust channel inside the ceiling panel through the air injection pipe. The hot and cold air is injected into the space below the ceiling panel through the exhaust channel to regulate the temperature of the space below the ceiling panel. Step 4: When there is no need to adjust the indoor temperature, perform the following sub-steps: A1, shut down the ducted air conditioner via the controller; A2, the controller starts the electric push rod, which drives the extrusion plate to move downward, drawing the filling medium in the sealing ring back into the storage tank, causing the sealing ring to contract and detach from the indoor wall, and then the electric push rod is turned off; A3, the controller starts the lifting mechanism, which drives the ceiling panel and sealing ring back to their initial positions.

[0016] In summary, this invention utilizes a ceiling panel connected to a lifting mechanism and a sealing ring to divide the interior space into two independent upper and lower spaces. Exhaust channels on the ceiling panel, connected to ductwork units, inject hot and cold air into the space below, reducing the volume of the space requiring temperature regulation, precisely adjusting local temperatures, and minimizing the volume of air undergoing ineffective heat exchange, thereby reducing energy consumption and meeting the energy requirements of green prefabricated buildings. Simultaneously, a storage tank connected to the sealing ring and filled with a filling medium is used. The up-and-down movement of a pressing plate within the tank allows for the filling and retraction of the filling medium, ensuring the sealing ring adheres tightly to the interior wall and works in conjunction with the ceiling panel to achieve airtight isolation of the interior space, further improving energy efficiency. Furthermore, millimeter-wave radar and a solenoid valve within the exhaust channel enable directional exhaust of hot and cold air, compressing and driving away the air below the ceiling panel before the sealing ring expands, further reducing the volume of air requiring heat exchange and further lowering energy consumption.

[0019] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0020] Implementation method 1: Figures 1-9 This invention illustrates an intelligent ceiling system for prefabricated green building construction, comprising a ceiling panel 1, a lifting mechanism 2 fixedly connected to the ceiling at the upper center of the ceiling panel 1, the lifting mechanism 2 being used to move the ceiling panel 1 up and down, a sealing ring 3 fixedly connected to the outer side of the ceiling panel 1, forming an annular gap between the sealing ring 3 and the interior wall for airflow, a hollow cavity 301 formed inside the sealing ring 3, a filling pipe 4 fixedly connected to the upper end of the sealing ring 3, the filling pipe 4 being a soft plastic pipe, the filling pipe 4 being connected to a storage tank 5 fixedly connected to the ceiling, the storage tank 5 being filled with a filling medium, an extrusion plate 6 slidably connected inside the storage tank 5, an electric push rod 7 fixedly connected to the extrusion plate 6, the electric push rod 7 driving the extrusion plate 6 to move inside the storage tank 5, extruding the filling medium into the hollow cavity 301 of the sealing ring 3, causing the sealing ring 3 to expand and abut against the interior wall, the expanded sealing ring 3 and the ceiling panel 1 working together to divide the interior space into two independent spaces with no airflow exchange; Please see Figure 3The ceiling panel 1 has an exhaust channel that communicates with the cavity below the ceiling panel 1. The exhaust channel is connected to an air injection pipe 12 that is fixedly connected to the upper end of the ceiling panel 1. The end of the air injection pipe 12 away from the ceiling panel is fixedly connected to a duct fan 13. The duct fan 13 is fixedly connected to the ceiling. The duct fan 13 injects hot and cold air into the exhaust channel through the air injection pipe 12. The airflow is injected into the space below the ceiling panel 1 through the exhaust channel. An infrared distance sensor 9 is fixedly connected to the lower end face of the ceiling panel 1. The lifting mechanism 2, the electric push rod 7, the infrared distance sensor 9 and the duct fan 13 are all electrically connected to the same controller 10. The controller 10 is fixedly connected to the interior wall.

[0021] For details, please refer to Figure 8 and Figure 9 When using it, the following steps are included: Step 1: Start the lifting mechanism 2 through the controller 10. The lifting mechanism 2 drives the ceiling panel 1 and the sealing ring 3 to move downward. At the same time, the infrared distance sensor 9 detects the height of the ceiling panel 1 from the ground in real time. When the ceiling panel 1 moves to the set height, the lifting mechanism 2 is turned off. It should be noted that controller 10 is a controller with a touch screen display, which is an existing device and will not be described in detail in this application; Step 2: Controller 10 starts electric push rod 7. Electric push rod 7 drives extrusion plate 6 to move upward in storage tank 5. Extrusion plate 6 injects filling medium in storage tank 5 into hollow cavity 301 of sealing ring 3 through injection pipe 4. After sealing ring 3 expands, it abuts against the indoor wall. The expanded sealing ring 3 and ceiling plate 1 divide the indoor space into two independent spaces, upper and lower. Step 3: Controller 10 starts the duct air conditioner 13. The duct air conditioner 13 injects hot and cold air into the exhaust channel inside the ceiling panel 1 through the air injection pipe 12. The hot and cold air is injected into the space below the ceiling panel 1 through the exhaust channel to regulate the temperature of the space below the ceiling panel 1. It should be noted that the duct unit 13 is existing technology, and its structure, pipe connection method and working principle are all existing technology, which will not be described in detail in this application; Step 4: When there is no need to adjust the indoor temperature, perform the following sub-steps: A1, shut down the duct unit 13 via controller 10; A2, Controller 10 starts the electric push rod 7, the electric push rod 7 drives the extrusion plate 6 to move downward, draws the filling medium in the sealing ring 3 back into the storage tank 5, causing the sealing ring 3 to contract and detach from the indoor wall, and then closes the electric push rod 7; A3, Controller 10 starts the lifting mechanism 2, and the lifting mechanism 2 drives the ceiling panel 1 and the sealing ring 3 back to the initial position.

[0022] Compared to traditional prefabricated building ceilings, this invention uses a ceiling panel 1 connected to a lifting mechanism 2 and a sealing ring 3. The ceiling panel 1 and the expanded sealing ring 3 divide the interior space into two independent spaces, upper and lower. Exhaust channels on the ceiling panel 1 and a duct unit 13 connected to these channels inject hot and cold air into the space below the ceiling panel 1, reducing the volume of the space requiring temperature regulation, precisely adjusting the local temperature, and reducing the volume of air undergoing ineffective heat exchange, thereby reducing energy consumption and meeting the energy requirements of green prefabricated buildings. Simultaneously, a storage tank 5 connected to the sealing ring and filled with a filling medium is used. The up-and-down movement of the extrusion plate 6 within the storage tank 5 allows for the filling and retraction of the filling medium, ensuring the sealing ring 3 fits tightly against the interior wall. This, combined with the ceiling panel 1, achieves a sealed and isolated interior space, further improving energy efficiency.

[0023] Please see Figure 2 and Figure 4 The lifting mechanism 2 is one of a hydraulic cylinder and a winch. The air injection pipe 12 includes a fixed pipe 1201 that is fixedly connected to the air outlet of the air duct machine 13. A sliding pipe 1202 is slidably connected inside the fixed pipe 1201. The sliding pipe 1202 is fixedly connected to the ceiling plate 1 and connected to the exhaust channel.

[0024] Specifically, when the lifting mechanism 2 is a hydraulic cylinder, the movable end of the hydraulic cylinder is fixedly connected to the center of the upper surface of the ceiling panel 1, and the fixed end of the hydraulic cylinder is fixedly connected to the ceiling. When the lifting mechanism 2 is a winch, the steel cable on the winch is fixedly connected to the center of the upper surface of the ceiling panel 1, and the frame of the winch is fixedly connected to the ceiling.

[0025] Please see Figure 3 Storage tank 5 is a hollow cylindrical structure, extrusion plate 6 is a disc-shaped structure, extrusion plate 6 slides against the inner wall of storage tank 5, electric push rod 7 is fixedly connected to the lower end face of storage tank 5, and the movable end of electric push rod 7 extends into storage tank 5 and is fixedly connected to the lower end face of extrusion plate 6.

[0026] Specifically, the movable end of the electric push rod 7 drives the extrusion plate 6 to move up and down inside the storage tank 5, thereby realizing the discharge and suction of the filling medium.

[0027] In this embodiment, the sealing ring 3 is made of rubber material, the ceiling board 1 is either fiber cement board or extruded polystyrene board, the filling medium is either air or hydraulic oil, and the volume of the storage tank 5 is larger than that of the hollow cavity 301.

[0028] Specifically, by using either fiber cement board or extruded polystyrene board for the ceiling panel 1, the ceiling panel 1 has better thermal insulation performance, further improving the thermal insulation performance of the ceiling panel 1 and reducing heat exchange. In addition, since temperature changes will cause thermal expansion and contraction of the sealing ring 3, by injecting filling medium, the sealing ring 3 is improved to better fit with the interior wall, further improving the sealing and isolation effect against airflow.

[0029] Please see Figure 3 The sealing ring 3 has a rectangular frame structure, the hollow cavity 301 is an annular cavity, and multiple vertically equidistant protrusions 302 are fixedly connected to the outer wall of the sealing ring 3.

[0030] Specifically, after the filling medium is injected into the sealing ring 3, the sealing ring 3 expands synchronously at all positions, and the multiple vertically equidistant protrusions 302 come into contact with the indoor wall, further improving the sealing effect of the sealing ring 3 and reducing the exchange of gas and heat between the upper and lower spaces of the ceiling panel 1.

[0031] Please see Figure 3 A pressure sensor 8 is fixedly connected to the upper end face of the extrusion plate 6. The pressure sensor 8 is electrically connected to the controller 10. The controller 10 includes an alarm module, and the input terminal of the alarm module is connected to the pressure sensor 8.

[0032] Specifically, after the filling medium is injected into the sealing ring 3, the controller 10 activates the pressure sensor 8 to monitor the pressure of the filling medium in real time. When the pressure of the filling medium is lower than the set pressure threshold, it indicates that the filling medium has leaked. The alarm module of the controller 10 issues an alarm command to remind the operator to carry out maintenance. It should be noted that when the filling medium leaks, the sealing ring 3 cannot expand fully, and the sealing effect of the sealing ring 3 on the annular gap is poor, affecting the sealing effect of the segmentation. In addition, the causes of filling medium leakage include, but are not limited to, damage to the sealing ring 3, the filling pipe 4, and the storage tank 5.

[0033] Please see Figure 6 and Figure 7 The lifting mechanism 2 has a plurality of damping cylinders 11 evenly distributed on its outer side. Each damping cylinder 11 includes an outer cylinder 1101 fixedly connected to the ceiling. A sliding rod 1102 is slidably connected inside the outer cylinder 1101. The sliding rod 1102 extends to the bottom of the outer cylinder 1101 and is fixedly connected to the ceiling panel 1. A sliding disc 1103 is fixedly connected to the upper end of the sliding rod 1102 and is slidably connected to the inner wall of the outer cylinder 1101. The sliding disc 1103 has evenly distributed flow holes 1104. The outer cylinder 1101 is filled with hydraulic oil.

[0034] Specifically, multiple damping cylinders 11 are used as anti-fall devices and buffer devices. When the ceiling panel 1 separates from the lifting mechanism 2, the multiple damping cylinders 11 use the resistance encountered by the internal hydraulic oil flowing from the flow hole 1104 to slow down the falling speed of the ceiling panel 1. The outer cylinder 1101 limits the sliding rod 1102 and the sliding plate 1103, thereby reducing the probability of the ceiling panel 1 falling.

[0035] The second implementation method: Figure 10 An intelligent ceiling system for prefabricated green building construction is shown. Based on the first embodiment, the exhaust channel includes a horizontal channel 101 opened on the upper part of the ceiling panel 1. The horizontal channel 101 is connected to a vertical channel 103 through a vertical channel 102. There are multiple vertical channels 103, and the multiple vertical channels 103 are arranged in parallel and at equal intervals. The vertical channels 103 are connected to multiple nozzles 104, and the nozzles 104 extend to the lower end face of the ceiling panel 1.

[0036] Specifically, it improves the uniformity of airflow injected into the space below the ceiling panel 1.

[0037] Please see Figure 4 and Figure 10 A solenoid valve 14 is fixedly connected inside the vertical channel 102, and a millimeter-wave radar 15 is fixed on the lower end face of the ceiling panel 1. Both the solenoid valve 14 and the millimeter-wave radar 15 are electrically connected to the controller 10.

[0038] Specifically, in use, the difference from the first embodiment is that after the ceiling panel 1 is moved to the set height, the duct fan 13 and the solenoid valve 14 located in the middle of the ceiling panel 1 are started first to inject hot and cold air into the space below the ceiling panel 1. The injected hot and cold air is used to compress the original air below the ceiling panel 1, so that the original air is squeezed into the space above the ceiling panel through the annular gap between the sealing ring 3 and the indoor wall, further reducing the volume of air that needs to be exchanged for heat. It should be noted that, since cold air tends to sink compared to hot air, it is more effective to drive the hot air in the space below the ceiling panel 1 into the space above the ceiling panel 1 during summer cooling. However, it is less effective to drive the cold air in the space below the ceiling panel 1 during winter heating. Nevertheless, in the initial stage of heating, it still has a certain squeezing and driving effect on the cold air below the ceiling panel 1, thus reducing the volume of air that needs to be exchanged for heat. In addition, by setting the air driving time, the electric push rod 7 is activated after the driving time ends to squeeze and seal the sealing ring 3. In addition, the position and height of people in the room are detected by millimeter-wave radar 15, and then hot and cold air is injected by opening the solenoid valve 14 located near the people to reduce the discomfort caused by direct airflow to people, while improving the temperature regulation speed of the space where people are located. It should be noted that although the indoor space is enclosed by doors, windows and ceiling panels 1, it is not an absolutely thermally sealed space. After the hot and cold airflow is injected into the space below the ceiling panels 1, it will continuously exchange heat with the external environment. Through millimeter-wave radar 15, the corresponding solenoid valves 14 in the space near the people are opened, so that when people have the same body temperature experience, the amount of ineffective hot and cold airflow is reduced, thereby reducing the operating power of the duct unit 13. Especially when people in the space stay in a fixed position for a long time (such as watching TV, eating, or sleeping at night, the position of people does not change for a long time), the required operating power of the duct unit 13 is further reduced, and energy consumption is further reduced.

[0039] Please see Figure 3 and Figure 6 Multiple lighting lamps 16 are fixedly connected to the lower end face of the ceiling panel 1, and the lighting lamps 16 are electrically connected to the controller 10.

[0040] Specifically, the height of the lighting lamp 16 on the ceiling panel 1 is detected by the infrared distance sensor 9, and the lighting power of the lighting lamp 16 is controlled to adapt to real-time lighting needs and reduce energy consumption.

[0041] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
