Technical Field

[0001] This utility model relates to the field of greenhouses, specifically a multifunctional hot and humid air circulation greenhouse system for concrete curing. Background Technology

[0002] The multifunctional hot and humid air circulation greenhouse system for concrete curing is an intelligent curing facility that integrates precise temperature and humidity control, heat energy recycling, and automated management. It is primarily used to accelerate concrete hardening, improve strength development stability, and prevent cracking. Through structural design, environmental control, and equipment coordination, the system achieves dynamic optimization of the curing environment.

[0003] A search revealed that publication number CN220986885U discloses a greenhouse system, which includes a greenhouse and a circulating water pipe system laid underground within the area of ​​the greenhouse. The system also includes a heat pump device configured to thermally connect the air conditioning system of the data center to the circulating water pipe system, transferring heat from the air conditioning system to the circulating water pipe system. This allows the data center to be cooled while the greenhouse is being heated. The greenhouse system of this invention can recover waste heat from the data center, thus achieving heating of the greenhouse in a relatively green and environmentally friendly way, and simultaneously utilizing the cold source within the greenhouse to cool the data center.

[0004] There is a problem in the aforementioned comparative documents. Specifically, the winter curing of large-volume concrete is a key link in ensuring the quality of the project. Especially in low-temperature environments, the cement hydration reaction slows down, and the internal and external temperature difference stress increases, which can easily lead to problems such as cracks and insufficient strength. Existing winter curing technologies include heat storage methods, warm shed methods, and comprehensive thermal insulation curing technologies. However, existing technologies have problems such as insufficient temperature difference control precision, high energy consumption and serious environmental pollution, lack of humidity control, limited adaptability to extreme environments, and poor traceability of curing data. In view of this, the inventor urgently needs to invent a multi-functional hot and humid air circulation greenhouse system for construction, so as to further intelligently control the greenhouse system and achieve the purpose of energy saving and efficiency improvement. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a multifunctional hot and humid air circulation greenhouse system for concrete curing, so as to solve the technical problems of insufficient control precision and high energy consumption of traditional greenhouse systems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional hot and humid air circulation greenhouse system for concrete curing, comprising a lightweight greenhouse module, a hot and humid air circulation module, and an intelligent control module, wherein:

[0007] The lightweight greenhouse module consists of a double-layer PVC inflatable membrane and a foldable aluminum alloy frame. The frame is connected by snap-fit. The lightweight greenhouse module is used to maintain a constant temperature for concrete curing inside the greenhouse.

[0008] The hot and humid air circulation module includes a hot air unit and a humid air unit. The hot air unit uses an electric heating tube and a solar collector connected in parallel to precisely adjust the air volume and speed of the hot air according to the real-time monitoring of the temperature inside the greenhouse. The humid air unit uses an ultrasonic humidifier inside and a steam pipe outside to quickly increase the humidity in the greenhouse environment.

[0009] The hot and humid air circulation module also includes a hot and humid air premixing chamber. Inside the greenhouse, there is a hot and humid air premixing chamber for mixing the hot air with the humid air generated by the humid air unit. On one side of the hot and humid air premixing chamber, there is an insulated air duct for conveying the premixed hot and humid air mixture. At the four corners inside the greenhouse, there are swirling nozzles for conveying the humid air to generate a strong rotating motion when it is sprayed out.

[0013] Furthermore, the top of the greenhouse module is provided with a mounting plate for installing solar panels, and several sets of the mounting plates are laid along the axis of the foldable aluminum alloy frame.

[0015] Furthermore, the bottom corners of the greenhouse module are equipped with water-filled sandbags for fixing a foldable aluminum alloy frame.

[0016] By adopting the above technical solution, the bottom corner water-filled sandbags are gravity-anchored to the foldable aluminum alloy frame, which enhances the overall wind resistance and stability of the greenhouse and avoids the maintenance environment from being affected by external disturbances.

[0017] Furthermore, the mounting plate has a through groove on its inner side, and a locking block for engaging is provided on the lower side of the groove.

[0018] By adopting the above technical solution, the sliding groove running through the inner side of the mounting plate and the lower locking block form a sliding locking structure, realizing the rapid positioning and installation of the solar panel and significantly improving construction efficiency.

[0019] Furthermore, mounting blocks for fixing the solar panel are symmetrically arranged at two corners of the surface of the solar panel.

They are fixed to the mounting plate by bolts or clips, effectively dispersing external loads and preventing the panel from deforming or cracking.

[0021] Furthermore, the greenhouse module is provided in several groups, and connecting plates are provided at the aluminum alloy frame of the several groups of greenhouse modules.

[0023] Furthermore, an arc-shaped water trough is fixedly connected to the upper side of the connecting plate, and the water trough is arranged along the axial direction of the connecting plate.

[0024] By adopting the above technical solution, the arc-shaped water trough fixed on the upper side of the connecting plate extends along the axial direction, efficiently collecting rainwater and condensate from the roof, providing an auxiliary water source for the humidification operation of the humidification unit, and reducing dependence on external water supply.

[0025] Furthermore, a fixing bracket is provided between the connecting plate and the aluminum alloy frame, and the fixing bracket is bolted to the aluminum alloy frame.

[0026] By adopting the above technical solution, the fixed brackets set between the connecting plate and the aluminum alloy frame are connected by bolts to form a triangular support structure, which greatly enhances the wind pressure resistance of the multi-module splicing nodes.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] In this embodiment:

[0037] A multifunctional hot and humid air circulation greenhouse system for concrete curing, such as Figure 1-4 As shown, it includes a lightweight greenhouse module 1, a hot and humid air circulation module 8, and an intelligent control module 9, wherein:

[0038] The lightweight greenhouse module 1 consists of a double-layer PVC inflatable film and a foldable aluminum alloy frame. The frame is connected by snaps. The lightweight greenhouse module 1 is used to maintain a constant temperature for concrete curing inside the greenhouse.

[0039] The hot and humid air circulation module 8 includes a hot air unit and a humid air unit. The hot air unit uses an electric heating tube and a solar collector connected in parallel to precisely adjust the air volume and speed of the hot air according to the real-time monitoring of the temperature inside the greenhouse. The humid air unit uses an ultrasonic humidifier inside and a steam pipe outside to quickly increase the humidity in the greenhouse environment.

[0040] The hot and humid air circulation module 8 also includes a hot and humid air premixing chamber. Inside the greenhouse, there is a hot and humid air premixing chamber for mixing the hot air with the humid air generated by the humid air unit. On one side of the hot and humid air premixing chamber, there is an insulated air duct for conveying the premixed hot and humid air mixture. At the four corners inside the greenhouse, there are swirling nozzles for conveying the humid air to generate a strong rotating motion when it is sprayed out.

[0041] The intelligent control module 9 includes an internal sensor group and a greenhouse temperature sensor. The internal sensor group is detachably connected to the hot air unit, the humid air unit, and the hot and humid air premixing chamber to detect the real-time temperature and humidity. The greenhouse temperature sensor is set at the four corners to detect the greenhouse temperature in real time.

[0042] The intelligent control module 9 also includes a PLC main controller. The hot air unit, humidity unit, internal sensor group, and greenhouse temperature sensor are electrically connected to the PLC main controller to control the other modules in real time. Through the lightweight greenhouse module 1's PVC double-layer inflatable film and foldable aluminum alloy frame, it can be quickly disassembled and transported, significantly reducing construction and deployment costs. Its sealed structure provides a stable heat preservation environment for concrete curing. The hot air unit of the hot and humid air circulation module 8 uses a solar collector and electric heating tube in parallel to prioritize the use of renewable energy to reduce energy consumption. The humidity unit uses a dual-mode collaboration of ultrasonic humidifier and steam pipe to meet the needs of rapid humidification. The hot and humid air premixing chamber forces the airflow to be mixed and then evenly diffused through the four corner swirling nozzles to completely eliminate temperature and humidity dead zones. The intelligent control module 9 relies on the four corner temperature sensors and the PLC main controller to collect multi-source data in real time and dynamically adjust the heat source switching, fan air volume, and humidification start and stop to form a closed-loop precise control to ensure a constant temperature and humidity environment for curing.

[0043] See Figure 1 , Figure 2 , Figure 3 , Figure 4The top of the greenhouse module 1 is equipped with mounting plates 4 for installing solar panels 2. Several sets of mounting plates 4 are laid along the axis of the foldable aluminum alloy frame. These mounting plates 4, laid along the frame axis on the greenhouse top, provide a standardized bearing surface for the solar panels 2, achieving large-area coverage of the solar energy collection device. This directly powers the heat exchange unit, reducing dependence on external energy sources. The modular installation method allows for flexible expansion or adjustment of the solar panel layout according to maintenance needs, improving system adaptability. The parallel and complementary design of solar energy and electric heating pipes further enhances energy utilization efficiency, providing a stable guarantee for continuous heating.

[0044] See Figure 1 , Figure 2 , Figure 3 , Figure 4 At the bottom corner of the greenhouse module 1, there are water-filled sandbags 7 for fixing a foldable aluminum alloy frame. The water-filled sandbags 7 at the bottom corners are gravity-anchored to the foldable aluminum alloy frame, which enhances the overall wind resistance and stability of the greenhouse and avoids the maintenance environment from being affected by external disturbances. The sandbags can be quickly filled with water or drained, taking into account both the need for lightweight transportation and on-site stability. This design is suitable for temporary maintenance projects. This design does not require complex foundation construction, which greatly shortens the construction period and reduces civil engineering costs.

[0045] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The inner side of the mounting plate 4 is provided with a through groove 5, and the lower side of the groove 5 is provided with a locking block 6 for locking. The through groove 5 on the inner side of the mounting plate 4 and the lower locking block 6 form a sliding locking structure, which realizes the rapid positioning and installation of the solar panel 2, significantly improving construction efficiency. This design allows the solar panel 2 to be easily disassembled during maintenance or replacement, reducing the later operation and maintenance costs. The through characteristic of the groove 5 ensures a stable connection between the mounting plate 4 and the frame, avoids component displacement due to wind load vibration, and ensures the long-term reliability of the solar collection system.

[0046] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The solar panel 2 has symmetrical mounting blocks 3 at two corners of its surface for fixing the solar panel 2. The mounting blocks 3 at the two corners of the solar panel 2 provide uniform force support and are fixed to the mounting plate 4 by bolts or clips. This effectively disperses external loads and prevents the panel from deforming or breaking. The symmetrical layout of the mounting blocks 3 simplifies the installation process and ensures a tight fit between the solar panel 2 and the mounting plate 4, maximizing the solar energy absorption efficiency. The modular design further adapts to the flexible configuration of solar panels of different specifications.

[0047] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The greenhouse module 1 is set with several groups, and the aluminum alloy frame of the greenhouse module 1 is equipped with connecting plates 10. Multiple greenhouse modules 1 can be expanded laterally through the connecting plates 10 at the aluminum alloy frame to meet the continuous curing requirements of large-span concrete components. The rigid connection of the connecting plates 10 enhances the overall structural stability and avoids deformation at the splicing points of multiple modules due to thermal expansion and contraction or external forces. The modular design significantly improves the system deployment flexibility and can quickly adjust the coverage area according to the project scale.

[0048] See Figure 1 , Figure 2 , Figure 3 , Figure 4 An arc-shaped water trough 12 is fixedly connected to the upper side of the connecting plate 10. The water trough 12 is set along the axial direction of the connecting plate 10. The arc-shaped water trough 12 fixed to the upper side of the connecting plate 10 extends along the axial direction, efficiently collecting rainwater and condensate from the roof, providing an auxiliary water source for the humidification operation of the humidification unit, reducing dependence on external water supply. The arc-shaped structure of the water trough 12 optimizes the water flow direction, preventing corrosion or algae growth caused by water accumulation. The utilization of rainwater resources further reduces system operating costs and improves sustainability.

[0049] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A fixed bracket 11 is provided between the connecting plate 10 and the aluminum alloy frame. The fixed bracket 11 is bolted to the aluminum alloy frame. The fixed bracket 11 between the connecting plate 10 and the aluminum alloy frame is bolted to form a triangular support structure, which greatly enhances the wind pressure resistance and torsion resistance of the multi-module splicing node. The bolt connection method facilitates quick assembly and disassembly on site, adapting to the flexible needs of temporary maintenance projects. The rigid support design ensures the long-term load-bearing stability of the extended components such as the water tank 12, ensuring the reliable operation of the system throughout its entire life cycle.

[0050] The implementation principle of this embodiment is as follows: This concrete curing shed system quickly constructs a closed space through a lightweight shed module 1, the roof mounting plate 4 fixes the solar panel 2 to collect solar energy, multiple sheds are expanded by bolting the connecting plate 10 to the fixed bracket 11, and the top water tank 12 assists in water collection.

[0051] In the hot and humid air circulation module 8, the solar collector and electric heating tube are connected in parallel for heating, the fan delivers air precisely, the ultrasonic humidifier and steam pipe work together to supply humidity, and the hot air and humid air are forcibly mixed in the hot and humid air premixing chamber and then transported to the four corners of the greenhouse through the heat-insulated air duct, and sprayed out by the swirl nozzle to achieve uniform diffusion of temperature and humidity.

[0052] The intelligent control module 9 monitors the temperature in real time through an internal sensor group and temperature sensors at the four corners of the greenhouse. In this embodiment, the model of the temperature sensor is not limited, as long as it can detect the temperature inside the greenhouse. At the same time, the PLC main controller dynamically regulates the system: switching the heat source as needed, adjusting the power of the electric heating tube and the speed of the fan, controlling the start and stop of the humidification unit and the steam on and off, and optimizing the mixing ratio to ensure constant temperature and humidity throughout the greenhouse, which is highly efficient and energy-saving to meet the needs of concrete curing.
