Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, and in particular to a prefabricated building curtain wall insulation board. Background Technology

[0002] Prefabricated buildings have become the mainstream development direction of the modern construction industry due to their advantages of high construction efficiency, low environmental pollution and high degree of standardization. As the core external enclosure component of prefabricated buildings, curtain wall insulation panels have multiple functions such as wall protection, thermal insulation and appearance decoration. Their structural performance, assembly efficiency and degree of integration directly affect the overall quality and energy consumption of prefabricated buildings.

[0003] Currently, most prefabricated building curtain wall insulation panels on the market adopt a simple composite panel splicing structure, with a single overall structural design and many defects in practical applications. First, the inner and outer protective panels, insulation core panels and surrounding edge sealing structures of traditional insulation panels are mostly fixed by bolts, glue, or simple plug-in methods. The assembly process is cumbersome, disassembly and maintenance are inconvenient, and the connection structure has poor stability. Under the long-term influence of building vibration, environmental temperature difference deformation, and wind and rain erosion, problems such as panel misalignment, loose splicing, and falling off are very likely to occur, which greatly reduces the structural safety and service life of the curtain wall.

[0004] Secondly, existing curtain wall insulation panels have limited functionality, mostly providing only basic thermal insulation and protection. They cannot meet the energy-saving development needs of green buildings and are difficult to use for the self-sufficiency of clean energy on building facades, resulting in limited energy-saving and consumption-reducing effects. Furthermore, some curtain wall insulation panels with integrated photovoltaic power generation structures often use fixed welded or integrated photovoltaic modules, making disassembly and maintenance difficult and increasing the cost of subsequent photovoltaic equipment repair and replacement. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a prefabricated building curtain wall insulation board.

[0008] Preferably, each of the four T-shaped inserts has a reset groove, and the four locking plates are slidably installed in the four reset grooves respectively. One end of the first spring is fixedly installed on the other side of each of the four locking plates, and the other end of the first spring is fixedly connected to the inner wall of the reset groove.

[0009] Preferably, the solar power generation module includes a support plate, which is installed on the side of the outer protective plate away from the middle core plate. The support plate has fixing holes, and a solar panel is fixedly installed in the fixing holes.

[0010] Preferably, the bearing plate has two rectangular positioning holes, and two positioning seats are fixedly installed on one side of the outer protective plate. The two positioning seats are respectively inserted into the two rectangular positioning holes, and rectangular stop grooves are provided on the side of the two positioning seats that are far apart from each other.

[0011] Preferably, a sliding opening is provided on the inner wall of the side of the two rectangular positioning holes that are far apart from each other, and a sliding plate is slidably installed in the sliding opening. A stop plate is fixedly installed on the side of the two sliding plates that are close to each other. The two stop plates are respectively engaged with two rectangular stop grooves. A pull groove is provided on the outer side of the two sliding plates, and the pull groove allows a finger to be inserted to facilitate pulling the sliding plate.

[0012] Preferably, spring grooves are provided on the top and bottom inner walls of the sliding port, and limit blocks are slidably installed in both spring grooves. The limit blocks are fixedly connected to the sliding plate, and one end of a second spring is fixedly installed on one side of the limit block. The other end of the second spring is fixedly connected to one side of the inner wall of the spring groove.

[0013] Preferably, each of the two positioning seats has a bearing groove on the side away from each other, and a second magnet is fixedly installed in each of the two bearing grooves. Each of the two sliding plates has a groove on the side close to each other, and an iron sheet is fixedly installed in the groove. The second magnet is used to attract the iron sheet.

[0014] Preferably, a guide groove is provided on one side of both the top plate and the bottom plate, and two guide plates are fixedly installed on one side of the bearing plate, with the two guide plates respectively engaging with the two guide grooves.

[0015] Preferably, two guide vertical plates are fixedly installed on one side of the bearing plate, and each of the two guide vertical plates has a guide groove on one side. The same reciprocating slide plate is slidably installed in the two guide grooves. A scraper is fixedly installed on one side of the reciprocating slide plate to remove impurities from the solar panel. A screw is rotatably installed in the guide groove and is threadedly connected to the reciprocating slide plate. A motor is fixedly installed on the guide vertical plate, and the output shaft of the motor is fixedly connected to one end of the screw.

[0016] The beneficial effects of the prefabricated building curtain wall insulation board described in this invention are as follows: This invention employs a modular splicing structure consisting of a three-layer composite panel and separate edge banding panels. Through the interlocking of clamping plates and slots, and the insertion of T-shaped inserts and slots, it achieves rapid positioning and splicing of the outer cladding panel, middle core panel, inner lining panel, left side panel, right side panel, top panel, and bottom panel. This eliminates the need for numerous bolts and adhesives for fixing, significantly simplifying the assembly process and effectively improving the efficiency of factory prefabrication and on-site construction of curtain wall insulation panels. Furthermore, the overall splicing structure is detachable, allowing for targeted disassembly and replacement during later stages of panel damage or equipment maintenance, without requiring complete removal, thus significantly reducing maintenance costs and construction losses.

[0017] This invention integrates a dual fixing structure of elastic mechanical locking and magnetic assisted locking on the basis of a plug-in structure. The locking plate inside the T-shaped plug automatically engages with the rectangular locking hole under the action of a first spring, achieving mechanical self-locking and preventing the plug-in structure from loosening and coming off. Simultaneously, the magnetic adhesion between the first magnet and the magnetic plate effectively offsets the structural deformation caused by building vibration and environmental temperature differences, preventing widening of splice gaps, panel misalignment, and detachment after long-term use. This significantly improves the overall structural strength, connection stability, and outdoor durability of the panel, ensuring the safety of the curtain wall.

[0018] This invention integrates solar power generation components on the outer side of the outer cladding panel, combining curtain wall insulation with photovoltaic power generation. While ensuring the building wall's thermal insulation and protective functions, it can autonomously collect solar energy and convert it into electricity, providing clean energy for the building, reducing building energy consumption, and aligning with the development needs of green and low-carbon buildings. Simultaneously, the photovoltaic components, relying on a support plate, positioning base, and locking structure, can be detachably installed. The photovoltaic components can be quickly unlocked and disassembled by pulling a sliding plate. The simple structure and convenient operation greatly facilitate the inspection, replacement, and maintenance of solar panels, solving the problem of difficult operation and maintenance of traditional integrated photovoltaic curtain walls.

[0019] This invention features an automated cleaning structure on the outer side of the support plate. A motor-driven screw rotates, causing a reciprocating slide plate and scraper to slide back and forth along the surface of the solar panel. This automatically cleans accumulated dust, leaves, oil, and other impurities from the panel surface, preventing impurities from blocking sunlight and reducing power generation efficiency, thus ensuring the continuous power generation performance of the photovoltaic modules. Simultaneously, this fully automated cleaning method replaces traditional manual high-altitude cleaning operations, completely eliminating the safety hazards of working at heights and significantly reducing the daily maintenance workload and costs of the curtain wall photovoltaic system.

[0020] This invention achieves precise alignment and assembly between the load-bearing plate, the main body of the insulation board, and the various edge-sealing panels through a multi-layered guiding and limiting mechanism involving guide plates and guide grooves, positioning seats, and rectangular positioning holes. This effectively avoids misalignment and displacement during assembly, improving overall assembly accuracy. The multi-layered limiting and locking structures work together to form a unified and stable structure for the entire insulation board, further enhancing the overall rigidity, sealing, wind resistance, and pressure resistance of the curtain wall insulation board, making it suitable for various outdoor applications of high-rise building curtain walls.

[0033] In this embodiment, two guide vertical plates 22 are fixedly installed on one side of the support plate 10. Each of the two guide vertical plates 22 has a guide groove 23 on one side. The same reciprocating slide plate 24 is slidably installed in the two guide grooves 23. A scraper 25 is fixedly installed on one side of the reciprocating slide plate 24. The scraper 25 is used to scrape off impurities on the solar panel 21. A screw 26 is rotatably installed in the guide groove 23. The screw 26 is threadedly connected to the reciprocating slide plate 24. A motor 27 is fixedly installed on the guide vertical plate 22. The output shaft of the motor 27 is fixedly connected to one end of the screw 26.

[0034] Working principle: I. Working principle of integral panel assembly splicing: The main body of the insulation board is a three-layer composite structure, consisting of an inner lining board 3, a middle core board 2, and an outer protective board 1 arranged from the inside out, forming the core insulation load-bearing body. The middle core board is the core insulation layer, responsible for blocking the heat transfer between the inside and outside of the building and realizing the thermal insulation function of the curtain wall. The outer protective board 1 plays the role of external protection and supporting photovoltaic modules. The inner lining board 3 is responsible for the inner sealing protection and ensures the integrity of the overall structure of the board.

[0035] The left and right sides, and top and bottom sides of the panel are edge-sealed and assembled using the left side panel 4, right side panel 5, top panel 6, and bottom panel 7, respectively. Six slots 35 are symmetrically formed on the inner sides of the left side panel 4 and right side panel 5. Cards 36 are fixedly assembled on both sides of the outer protective panel 1, the middle core panel 2, and the inner lining panel 3. During assembly, the six cards 36 are inserted one-to-one into the corresponding slots 35 to achieve left and right positioning and fixation of the three-layer panel, preventing misalignment or displacement of the three layers and ensuring the integrity of the composite panel.

[0036] Meanwhile, T-shaped inserts 28 are fixedly installed at the top and bottom of the left side panel 4 and the right side panel 5, for a total of four T-shaped inserts 28. T-shaped slots 29 matching the T-shaped inserts 28 are opened on the inner sides of the top panel 6 and the bottom panel 7, and the T-shaped slots 29 have a bidirectional opening structure for quick insertion and installation. During assembly, the four T-shaped inserts 28 are inserted into the four corresponding T-shaped slots 29 to achieve initial insertion and positioning of the left and right edge sealing panels and the upper and lower edge sealing panels, completing the splicing and assembly of the entire insulation board frame.

[0037] II. Working principle of the locking mechanism: To address the issues of loosening and poor connection stability in the plug-in structure, the T-shaped plug plate 28 integrates an elastic locking mechanism, which works in conjunction with the rectangular locking hole 32 on the inner wall of the T-shaped slot 29 to achieve self-locking. Each T-shaped plug plate 28 has a reset groove 30 inside, and a locking plate 31 is slidably installed inside the reset groove 30. The tail of the locking plate 31 is connected to a first spring, and the end of the first spring is fixed to the inner wall of the reset groove 30.

[0038] During the insertion and assembly process, when the T-shaped insert plate 28 is inserted into the T-shaped slot 29, the locking plate 31 is pressed to compress the first spring and retract into the reset groove 30 to avoid insertion jamming. When the T-shaped insert plate 28 is fully inserted, the locking plate 31 and the rectangular locking hole 32 are precisely aligned. At this time, the first spring releases its elastic thrust, pops the locking plate 31 out and locks it into the rectangular locking hole 32, realizing the mechanical locking of the insertion structure and preventing the T-shaped insert plate 28 from coming out.

[0039] Meanwhile, a magnetic absorbing piece 40 is fixed to the outside of the locking plate 31, and a first magnet 39 is fixed inside the rectangular locking hole 32. After the locking plate 31 is inserted into the locking hole, the first magnet 39 and the magnetic absorbing piece 40 magnetically adhere to each other, further enhancing the locking stability of the locking plate 31, offsetting the risk of loosening caused by vibration and temperature difference deformation, and greatly improving the overall assembly firmness of the plate.

[0040] III. Principles of Solar Power Generation Module Disassembly and Assembly: The outer cladding panel 1 is equipped with solar power generation components on its outer side, relying on the support plate 10 as the support substrate. The support plate 10 has a fixing hole 20 in the center for embedding and fixing the solar panel 21, so as to realize the photovoltaic power generation energy-saving function of the curtain wall panel.

[0041] The support plate 10 and the outer protective plate 1 adopt a detachable positioning and locking structure: two symmetrically distributed positioning seats 8 are fixed on the outer side of the outer protective plate 1, and the support plate 10 has two matching rectangular positioning holes 11. During assembly, the rectangular positioning holes 11 are inserted into the positioning seats 8 to achieve initial positioning. A rectangular stop groove 15 is provided on the outer side of the positioning seat 8, and the outer side of the rectangular positioning hole 11 is connected to the sliding port 12. The sliding plate 13 is slidably assembled inside the sliding port 12, and the stop plate 14 is fixed on the inner side of the sliding plate 13.

[0042] Spring grooves 17 are provided on the upper and lower inner walls of the sliding port 12. The limiting block 18 is connected to the groove by a second spring 19. The limiting block 18 is fixed to the sliding plate 13 as a whole. Under normal conditions, the second spring 19 is in the extended state, pushing the sliding plate 13 to slide inward, so that the stop plate 14 is inserted into the rectangular stop groove 15, thereby locking and fixing the bearing plate 10 and the positioning seat 8 to prevent the bearing plate 10 from falling off.

[0043] A second magnet 37 is fixed inside the bearing groove 38 of the positioning seat 8, and an iron sheet is embedded in the groove on the inner side of the sliding plate 13. In the locked state, the second magnet 37 and the iron sheet are magnetically attracted to each other, which helps to improve the locking stability. When it is necessary to disassemble and repair the photovoltaic module, the operator can pull the sliding plate 13 outward through the pull groove 16 on the outer side of the sliding plate 13 to compress the second spring 19, so that the stop plate 14 is disengaged from the rectangular stop groove 15, thereby releasing the lock and quickly removing the bearing plate 10 and the solar panel 21. The disassembly and assembly are convenient.

[0044] In addition, guide grooves 34 are provided on the outer sides of the top plate 6 and the bottom plate 7, and guide plates 33 are fixed on the upper and lower sides of the bearing plate 10. During assembly, the guide plates 33 are inserted into the guide grooves 34 to guide and limit the bearing plate 10 in the upper and lower directions, avoid assembly deviation, and further improve the installation accuracy and structural stability.

[0045] IV. Working Principle of Automatic Cleaning of Solar Panels To prevent dust and debris from accumulating and affecting photovoltaic power generation efficiency, an automatic cleaning mechanism is integrated on the outside of the support plate 10. The support plate 10 is fixed with two sets of symmetrical guide vertical plates 22. Guide grooves 23 are opened on the inner side of the guide vertical plates 22. The two sets of guide grooves 23 are slidably assembled with reciprocating slide plates 24 inside. The scraper 25 that is attached to the surface of the solar panel 21 is fixed on the inner side of the reciprocating slide plates 24.

[0046] A screw 26 is rotatably mounted inside the guide groove 23. The screw 26 and the reciprocating slide plate 24 form a threaded transmission engagement. A motor 27 is fixed to the outside of the guide vertical plate 22, and the output shaft of the motor 27 is fixedly connected to the end of the screw 26. During cleaning, the motor 27 starts and drives the screw 26 to rotate forward and backward. Through the threaded transmission, the reciprocating slide plate 24 moves up and down in a linear motion along the guide groove 23, simultaneously driving the scraper 25 to slide against the surface of the solar panel 21, thoroughly scraping away dust, stains, and debris.

[0047] To adapt to complex outdoor conditions such as strong winds, fluctuating temperatures, and minor earthquakes, and to improve the stability and service life of the panel structure, buffer pads are installed on the inner walls of the reset groove 30 and the spring groove 17. These pads effectively reduce noise generated by spring extension and contraction vibration, while also preventing long-term impact and wear on the metal structure. The end of the clamping plate 36 is equipped with an arc-shaped buffer end, and the bottom of the clamping groove 35 matches an arc-shaped groove structure. After clamping, a flexible and fitting structure is formed, which can buffer the structural extrusion force caused by wind pressure and temperature difference deformation, preventing the panel from cracking and the clamping from loosening.

[0048] Meanwhile, both the outer protective panel 1 and the inner lining panel 3 are made of high-strength flame-retardant aluminum alloy sheets with anodized anti-corrosion treatment. They have excellent corrosion resistance, aging resistance, and impact resistance, and can withstand outdoor wind, sand, rain, snow, and ultraviolet radiation, effectively extending the service life of the panels. The middle core panel 2 is bonded to the inner and outer panels using a high-temperature composite bonding process, which has high bonding strength and eliminates the problem of delamination.

[0049] Rubber sealing gaskets are embedded in the joints between the left side panel 4, right side panel 5, top panel 6, bottom panel 7 and the three-layer composite panel. Waterproof sealing strips are also bonded to the contact surfaces of the slot 35 and the plate 36, and the insertion surfaces of the T-shaped insert plate 28 and the T-shaped slot 29. Meanwhile, the top outer side of the top panel 6 has an integrally formed rainproof edge, and the bottom of the bottom panel 7 has a drainage groove. When two adjacent insulation panels are joined, the drainage grooves are interconnected, allowing for the rapid drainage of any small amount of rainwater seeping into the gaps. This prevents moisture from accumulating inside the panel, thus preventing the core panel from becoming damp and deteriorating, reducing its insulation performance, and preventing corrosion of the metal structure. The core panel 2 uses high-density polyurethane insulation material, uniformly filled with microporous sound-absorbing particles, combining thermal insulation and sound absorption / noise reduction properties. It effectively blocks the convection of hot and cold air between the inside and outside of the building, reducing air conditioning and heating energy consumption, and also effectively reduces outdoor noise transmission into the interior, improving the building's indoor quietness. Meanwhile, the interiors of the left side panel 4, right side panel 5, top panel 6, and bottom panel 7 are all filled with lightweight thermal insulation filler to compensate for the insulation shortcomings at the edge sealing positions, solve the problems of insulation discontinuity and thermal bridging at the edge sealing positions of traditional curtain wall panels, and achieve all-round insulation of the panel body without dead angles.

[0050] The solar panel 21 is electrically connected to an energy storage battery and a voltage regulator via wires. The energy storage battery is housed in a pre-drilled mounting slot inside the inner liner 3. The mounting slot is equipped with a sealed dustproof cover, which effectively stores electrical energy to supply power to the cleaning motor and intelligent control system, achieving self-generation and self-consumption without the need for external power supply, thus saving energy and protecting the environment. The voltage regulator prevents damage to circuit equipment from voltage fluctuations and lightning surges during thunderstorms, improving the electrical safety of the photovoltaic modules.

[0051] Example 2: The difference between this example and Example 1 is that, to achieve automated and intelligent cleaning of solar panels without manual operation, this solution adds a highly integrated intelligent control component. This component enables fully automatic cleaning logic with environmental adaptability, power linkage, and timed control. The overall control component consists of two parts: hardware units and software control programs. It has a complete structure, closed-loop logic, and can operate independently and stably. The specific hardware includes: an intelligent control box, a combined light and rain sensor, a power generation detection module, a relay drive module, a voltage regulator module, and signal transmission lines. The intelligent control box and the combined light and rain sensor are fixedly installed on the top of the guide vertical plate 22. The sensor adopts a waterproof and dustproof integrated package, which is suitable for outdoor open-air working environments of curtain walls. It can synchronously collect multi-dimensional environmental data such as ambient light intensity, rainfall status, and air dust concentration in real time. The intelligent control box integrates a single-chip microcomputer, which is electrically connected to the motor 27, solar panel 21, light and rain sensor, and power generation detection module through lines to realize full-process control of signal acquisition, logic operation, and command output.

[0052] This control component features three independent and interconnected cleaning modes, comprehensively covering various usage scenarios: The first is an environment-adaptive trigger mode. Light and rain sensors monitor outdoor environmental conditions in real time, accurately identifying scenarios such as rain stopping, fog dissipating, and sandstorms ending. When the environment changes from harsh to sunny and the surface is prone to residual dirt and dust, a trigger signal is immediately transmitted to the intelligent control box. Upon receiving the signal, the main control chip outputs a working command, automatically starting motor 27, driving screw 26 to rotate forward and backward, and causing scraper 25 to complete a full-area reciprocating cleaning operation from top to bottom and then from bottom to top, thoroughly removing rainwater residue, floating dust, and sand impurities from the surface. The second is a timed and quantitative cleaning mode. The intelligent control box has a built-in programmable timer program, allowing staff to adjust the cleaning schedule according to the local climate, dust concentration, and seasonal changes. The system defines and sets daily single cleaning, daily multiple cleaning, or weekly fixed-point cleaning work cycles to achieve routine preventative cleaning, preventing the long-term adhesion and solidification of dust and stubborn stains, and ensuring photovoltaic power generation efficiency from the source. Thirdly, it features a power threshold intelligent trigger mode. The intelligent control box is equipped with a power generation detection module that collects real-time high-frequency data on the real-time power generation and unit light power generation efficiency of the solar panel 21. The system has a preset standard power generation threshold, which can be adaptively calibrated according to the rated parameters of the solar panel and the ambient light reference value. When the power generation is detected to be continuously lower than the set threshold under the same light conditions, and normal power attenuation conditions such as cloudy days and nights are excluded, the system automatically determines that there is dust accumulation on the panel surface and actively triggers the cleaning program. This accurately adapts to the actual power generation conditions and starts the cleaning operation as needed, avoiding energy loss caused by ineffective cleaning.

[0053] The cleaning scraper 25 is made of highly elastic, wear-resistant, and flexible silicone material. The material's hardness has been optimized to combine wear resistance and anti-aging properties with flexible adhesion. During the reciprocating cleaning motion, it will not scratch or abrade the tempered glass and light-transmitting coating on the surface of the solar panel 21, effectively protecting the photovoltaic module's structure and light transmission performance. Simultaneously, the scraper 25's wiping contact surface edge is integrally molded with fine guiding textures, which can quickly guide and scrape away rainwater, mud, dust, and lint adhering to the panel surface during cleaning operations, preventing residual water stains and dried stains from causing secondary pollution, significantly improving cleaning uniformity and effectiveness. In addition, the intelligent control components are also equipped with delayed reset, overload protection, and sleep-life energy-saving logic: after a single cleaning operation is completed, the system automatically resets and goes into standby mode after a 30-second delay to avoid repeated triggering in a short period of time; if the motor stalls or is overloaded during operation, the system immediately cuts off power and stops the machine and locks the fault to prevent the equipment from burning out; when there is no sunlight at night and the photovoltaic modules stop working, the system automatically enters a low-power sleep mode, retaining only the sensor standby monitoring function, which greatly reduces energy consumption. The overall control system has a high degree of intelligence, strong fault tolerance, and significant energy-saving and consumption-reducing effects.
