[0004] When snow accumulates on the top of the existing twin-span temperature-controlled greenhouse in winter, it requires manual climbing to clear it, which is not only inefficient and labor-intensive, but also poses safety hazards. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dual-span temperature-controlled greenhouse, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A dual-span temperature-controlled greenhouse includes: a bottom frame comprising multiple sets of main columns and side columns, with two sets of side columns on the same plane located on either side of the main columns, and a first crossbar being provided at the top of both sets of side columns, through which the main columns are movably inserted; and two sets of polycarbonate sheet assemblies, which are positioned above the bottom frame for wind and snow resistance, each polycarbonate sheet assembly including a polycarbonate sheet body, a support plate, and a supporting plate; and a pushing assembly between the main columns and the polycarbonate sheet assemblies, the pushing assembly including a main mounting plate and a hydraulic telescopic cylinder.

[0007] According to the aforementioned twin-span temperature-controlled greenhouse, the bottom ends of multiple sets of main columns and side columns are fixedly installed on the ground, and the top of the side columns is fixed to the first crossbar by welding.

[0008] According to the aforementioned twin-span temperature-controlled greenhouse, two sets of roofs are fixed to the top of the first crossbar by welding. The roofs are arc-shaped and are on the same vertical plane as the first crossbar.

[0009] According to the aforementioned dual-span temperature-controlled greenhouse, the tops of multiple sets of main columns are welded and fixed with crossbeams. The support plate is fixedly installed on the side of the polycarbonate sheet body near the crossbeam. The cross section of the support plate is "right-angled". The support plate is engaged with one side of the crossbeam. A sealing rubber gasket is pasted and fixed on the inner wall of the support plate.

[0010] According to the aforementioned dual-span temperature-controlled greenhouse, multiple sets of main columns are movably connected through a main mounting plate, and the main mounting plate is fixed to the multiple sets of main columns by welding. Multiple sets of first mounting grooves are opened on both sides of the main mounting plate. A side mounting plate is fixedly installed on the side of the polycarbonate sheet body close to the main mounting plate. Multiple sets of second mounting grooves are opened on the side mounting plate. The two ends of multiple sets of hydraulic telescopic cylinders are movably installed between the corresponding first mounting grooves and second mounting grooves by pins.

[0011] According to the aforementioned double-span temperature-controlled greenhouse, a second crossbar is welded and fixed to one side of multiple sets of side columns. Multiple sets of rotating seats are fixedly installed at the top of the second crossbar. The rotating seats are located between two adjacent sets of first crossbars. The top of the support plate is fixedly connected to the side of the polycarbonate sheet body away from the support plate. The number of support plates corresponds one-to-one with the number of rotating seats. The end of the support plate away from the polycarbonate sheet body is movably connected to the rotating seat through a pin.

[0012] According to the aforementioned dual-span temperature-controlled greenhouse, a reinforcement unit is provided between two adjacent sets of side columns below the polycarbonate panel assembly. The reinforcement unit includes two sets of diagonal braces, which are symmetrical. The tops of the two sets of diagonal braces are welded and fixed to the second crossbar. Assembly seats are welded and fixed to the outer wall of the side column near the diagonal braces. Bolts and nuts are provided between the diagonal braces and the corresponding assembly seats.

[0013] This utility model provides a double-span, multi-unit temperature-controlled greenhouse. It has the following beneficial effects: (1) Multiple sets of main columns and side columns are fixed to the ground at the bottom. The design of welding the top of the side columns to the first horizontal bar and the main columns moving through the first horizontal bar forms a stable bottom load-bearing frame, which effectively enhances the overall integrity of the frame's longitudinal and transverse connections. It can stably support the subsequent installation of polycarbonate panels, roofs and other components, and prevent the frame from being misaligned or tilted due to load or external force. At the same time, an arc-shaped roof that is welded to the top of the first horizontal bar and is in the same vertical plane as the horizontal bar can ensure that the roof load is evenly transferred to the bottom frame, realize the initial top shading function of the greenhouse, resist the interference of external rain and slight impact on the greenhouse space, and lay a reliable foundation for the installation of core functional components.

[0014] (2) By setting up a polycarbonate panel assembly including the polycarbonate panel body, the support plate, and the support plate, the impact resistance of the polycarbonate panel body can resist wind and snow loads and prevent the greenhouse roof from being damaged by wind and snow. Its transparent material can also ensure sufficient light inside the greenhouse to meet the light requirements of crop growth. The support plate is engaged with the crossbeam and the inner wall is pasted with sealing rubber gaskets, which simplifies the installation process of the polycarbonate panel assembly, reduces the construction difficulty, and prevents rainwater from seeping into the greenhouse from the connection gaps, thus avoiding the dampness inside the greenhouse from affecting crop growth. Combined with the hydraulic system consisting of the push assembly, the hydraulic pump, and the PLC controller in the greenhouse, the PLC synchronously controls the hydraulic telescopic cylinder to drive the polycarbonate panel assembly to adjust the angle. In summer, it can tilt to reduce direct sunlight to lower the temperature inside the greenhouse, and in winter, it can gradually increase direct sunlight to raise the temperature inside the greenhouse, thus realizing dynamic temperature control and reducing the energy consumption of air conditioning, heating and other equipment. In winter, it can automatically remove snow by adjusting the angle, without the need for manual cleaning, which greatly improves the practicality and convenience of the greenhouse.

[0015] (3) By using bolts and nuts to fix two sets of symmetrical diagonal braces to the mounting base between the two adjacent sets of side columns and the second crossbar, the diagonal braces, side columns, and second crossbar form a triangular stable structure. With the help of the non-deformable properties of triangles, the ability of the greenhouse to resist wind and snow thrust is significantly enhanced, and the greenhouse is prevented from tilting or the frame is deformed due to lateral external forces. The hydraulic system is started to test the extension and retraction of the hydraulic telescopic cylinder, check the sealing performance of the rubber gasket of the pallet, and confirm the tightness of the bolts and nuts of the reinforcement unit to ensure that the angle adjustment of the polycarbonate panel components is smooth, there is no rainwater leakage in the greenhouse, and the structure is not loose. This further ensures the safety of the overall structure and the stability of the function of the greenhouse, effectively extends the service life of the equipment, and provides a long-term stable environment for the growth of crops in the greenhouse.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1-5 As shown, this utility model is a double-span temperature-controlled greenhouse, including a bottom frame. The bottom frame includes multiple sets of main columns 10 and side columns 11. The main columns 10 and side columns 11 are the main load-bearing components of the greenhouse. Two sets of side columns 11 on the same plane are located on both sides of the main columns 10. The top of the two sets of side columns 11 are jointly provided with a first crossbar 12, forming a stable bottom structure. The main columns 10 can move through the first crossbar 12. The bottom ends of the multiple sets of main columns 10 and side columns 11 are all fixedly installed on the ground. The top of the side columns 11 is fixed to the first crossbar 12 by welding. Two sets of canopies 28 are fixed to the top of the first crossbar 12 by welding. The canopies 28 are arc-shaped and are on the same vertical plane as the first crossbar 12. By setting the main columns 10 and side columns 11 to form the load-bearing system of the greenhouse, the canopies 28 and polycarbonate panel assemblies 13 and other components above can be stably supported.

[0020] like Figure 3 and Figure 4As shown, there are two sets of polycarbonate sheet components 13, which need to withstand wind and snow loads and ensure the lighting requirements inside the shed. The two sets of polycarbonate sheet components 13 are set above the bottom frame. The polycarbonate sheet component 13 includes a polycarbonate sheet body 18, a support plate 19 and a support plate 20. The top of multiple main columns 10 are welded and fixed to a crossbeam 17. The support plate 19 is fixedly installed on the side of the polycarbonate sheet body 18 near the crossbeam 17. The cross section of the support plate 19 is "right angle". The support plate 19 is engaged with one side of the crossbeam 17. A sealing rubber gasket is pasted and fixed on the inner wall of the support plate 19. By setting up the polycarbonate panel assembly 13, the greenhouse achieves the dual core functions of wind and snow resistance and light transmission. The impact resistance of the polycarbonate panel body 18 can withstand the impact of wind and snow, preventing the greenhouse roof from being damaged by wind and snow loads. At the same time, the transparent material ensures sufficient light transmission inside the greenhouse to meet the needs of crop growth. By setting up the interlocking design of the support plate 19 and the crossbeam 17, the installation process of the polycarbonate panel assembly 13 is simplified. By attaching and fixing the sealing rubber gasket to the inner wall of the support plate 19, rainwater is prevented from seeping in from the gaps. The crossbeam 17 is installed on the top of multiple main columns 10 to provide stable support for the polycarbonate panel assembly 13. This ensures that when the polycarbonate panel assembly 13 is subjected to wind and snow loads, the force can be evenly transmitted to the main columns 10, avoiding local stress concentration that could lead to component damage.

[0021] like Figure 2 and Figure 4As shown, a pushing assembly 15 is provided between the main column 10 and the polycarbonate sheet assembly 13. The pushing assembly 15 includes a main mounting plate 23 and a hydraulic telescopic cylinder 24. Multiple sets of main columns 10 are movably connected through the main mounting plate 23, and the main mounting plate 23 is fixed to the multiple sets of main columns 10 by welding. Multiple sets of first mounting grooves are opened on both sides of the main mounting plate 23. A side mounting plate 22 is fixedly installed on the side of the polycarbonate sheet body 18 near the main mounting plate 23. Multiple sets of second mounting grooves are opened on the side mounting plate 22. The two ends of the multiple sets of hydraulic telescopic cylinders 24 are movably installed between the corresponding first mounting grooves and second mounting grooves by pins. A second crossbar 16 is welded and fixed to one side of multiple sets of side columns 11. Multiple sets of rotating seats 21 are fixedly installed at the top of the second crossbar 16. The rotating seats 21 are located between two adjacent sets of first crossbars 12. The top of the support plate 20 is fixedly connected to the side of the polycarbonate sheet body 18 away from the support plate 19. The number of support plates 20 corresponds one-to-one with the number of rotating seats 21. The end of the support plate 20 away from the polycarbonate sheet body 18 is movably connected to the rotating seat 21 through a pin. The push assembly 15 includes a main mounting plate 23 and a hydraulic telescopic cylinder 24. The design of the hydraulic telescopic cylinder 24 enables the angle of the polycarbonate panel assembly 13 to be adjustable. In summer, the polycarbonate panel body 18 can be adjusted to a tilt angle to reduce the area exposed to direct sunlight and lower the temperature inside the greenhouse. In winter, it can be adjusted to a gentle angle to increase the area exposed to direct sunlight and raise the temperature inside the greenhouse. This perfectly meets the dynamic temperature control requirements of temperature-controlled greenhouses and reduces the energy consumption of air conditioning, heating and other equipment. In addition, on snowy days in winter, snow accumulates on the top of the polycarbonate panel assembly 13, which is inconvenient to clean manually. By adjusting the tilt angle of the polycarbonate panel body 18, the snow can be automatically cleared, making it more practical.

[0022] It should be noted that the greenhouse is equipped with a hydraulic pump, directional control valve, pressure control valve, flow control valve, oil tank, oil filter, oil pipe and PLC controller. The PLC controller synchronously controls multiple sets of hydraulic telescopic cylinders 24.

[0023] like Figure 5As shown, a reinforcement unit 14 is provided between two adjacent sets of side columns 11 below the polycarbonate panel assembly 13. The reinforcement unit 14 includes two sets of diagonal braces 25, which are symmetrical. The tops of the two sets of diagonal braces 25 are welded and fixed to the second crossbar 16. The outer wall of the side column 11 near the diagonal brace 25 is welded and fixed with an assembly seat 26. Bolts and nuts 27 are provided between the diagonal brace 25 and the corresponding assembly seat 26. By setting the diagonal brace 25, the side column 11, and the second crossbar 16 to form a triangular stable structure, it can effectively resist external forces such as strong winds and lateral snow thrust, avoid the greenhouse from tilting to the side or the frame from deforming, and ensure the safety of the overall greenhouse structure. The assembly seat 26 enables precise positioning and installation of the diagonal brace 25 and the side column 11, reducing construction errors. On the other hand, it increases the contact area between the diagonal brace 25 and the side column 11, reducing the local pressure of the diagonal brace 25 on the side column 11 and preventing the side column 11 from denting or cracking due to stress concentration.

[0024] The implementation principle of this utility model of a double-span temperature-controlled greenhouse is as follows: First, according to the design dimensions, the bottom ends of multiple sets of main columns 10 and side columns 11 are fixed to the ground to ensure that the columns are vertical and stable. Next, the top ends of two sets of side columns 11 in the same plane are fixed to the first horizontal bar 12 by welding, while allowing the main columns 10 to move through the first horizontal bar 12 to enhance the overall integrity of the longitudinal and transverse connections of the bottom frame. Finally, two sets of arc-shaped canopies 28 are welded to the top of the first horizontal bar 12 to ensure that the canopies 28 and the first horizontal bar 12 are in the same vertical plane, so that the canopy load can be evenly transferred to the bottom frame. This forms a basic structure that can support subsequent components and realizes the initial top protection and load-bearing capacity of the greenhouse.

[0025] Secondly, crossbeams 17 are welded to the top of multiple main columns 10 to provide a top support carrier for the polycarbonate panel assembly 13. Then, the support plate 19 of the polycarbonate panel assembly 13 is engaged with one side of the crossbeam 17, and the top of the support plate 20 is fixed to the side of the polycarbonate panel body 18 away from the support plate 19. The bottom end of the support plate 20 is movably connected to the rotating seat 21 through a pin. The main mounting plate 23 is welded and fixed to multiple main columns 10. A second crossbar 16 is welded to one side of the side column 11 and the rotating seat 21 is installed. Then, the two ends of the hydraulic telescopic cylinder 24 are connected to the first mounting groove of the main mounting plate 23 and the second mounting groove of the side mounting plate 22 of the polycarbonate panel body 18 through pins. Finally, a hydraulic pump, directional control valve, pressure control valve, flow control valve, oil tank, oil filter and PLC controller are installed in the greenhouse. A complete hydraulic circuit is formed by connecting oil pipes, so that the PLC controller can realize synchronous control of multiple hydraulic telescopic cylinders 24. Thus, the core functions of the greenhouse, such as wind and snow resistance, light transmission and polycarbonate panel angle adjustment, are realized.

[0026] Finally, two sets of symmetrical diagonal braces 25 are fixed between the mounting base 26 of the two adjacent sets of side columns 11 and the second crossbar 16 by bolts and nuts 27, so that the diagonal braces 25, the side columns 11, and the second crossbar 16 form a triangular stable structure, which enhances the greenhouse's ability to resist lateral wind and snow thrust. Then, overall debugging is carried out: the hydraulic system is started by the PLC controller, the extension and retraction of the hydraulic telescopic cylinder 24 is tested, and the angle adjustment of the polycarbonate panel assembly 13 is checked to see if it is smooth, such as the switching between tilting in summer and flat angle in winter. At the same time, the sealing rubber gasket of the support plate 19 is checked to see if it is sealed well and the bolts and nuts 27 of the reinforcement unit are tightened to ensure that the greenhouse structure is not loose and the function is normal, and finally a structurally safe and functionally complete double-span temperature-controlled greenhouse is formed.

[0027] The above embodiments are preferred implementations of this utility model. In addition, this utility model can be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
