[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] Referring to Figures 1 - 11 , in order to reduce the number of windows set on the surface of the solar greenhouse and also achieve the effect of indoor heat preservation, an intelligent greenhouse high-efficiency heat-preserving glass is provided, including an installation frame 1. The inner part of the installation frame 1 is respectively provided with an outer layer of glass 2, a middle layer of glass 3, and an inner layer of glass 4. The outer layer of glass 2, the middle layer of glass 3, and the inner layer of glass 4 are used as the outer facade light-transmitting and heat-preserving layer. On the one hand, it reduces the installation of a large number of windows in the Dutch Venlo-type glass greenhouse due to ventilation, avoids air leakage caused by poor window sealing, and reduces the heat preservation ability; on the other hand, the light transmittance of the outer layer of glass 2, the middle layer of glass 3, and the inner layer of glass 4 is reduced by 10-15% compared with ordinary insulating glass, but the thermal resistance value is increased by 5 times, greatly improving the heat preservation ability of the outer facade.

[0034] In order to realize the installation, fixation, and sealing operation of the middle layer of glass 3, the inner center inner wall of the installation frame 1 is fixedly bonded to the surface of the middle layer of glass 3 through sealant. Square partition boards 9 are respectively bonded to both sides of the middle layer of glass 3 through sealant. An installation groove 10 is opened on one side surface of the square partition board 9. A drying layer 11 is fixedly installed on the inner wall of the installation groove 10. A desiccant is provided on the inner wall of the drying layer 11. Drainage holes 12 are opened on both sides of the inner bottom wall of the installation frame 1.

[0035] Specifically, it is implemented as follows. The middle layer glass 3 is installed at the central position inside the installation frame 1. At the same time, square partitions 9 are installed on both sides of it to limit and support the middle layer glass 3 by using the square partitions 9 on both sides, so that the middle layer glass 3 is vertically installed. A drying layer 11 is arranged on one surface of the square partition 9 to facilitate the drying operation inside the position space cavity on both sides of the middle layer glass 3 by using desiccants, and to avoid the generation of water vapor.

[0036] A sealing mechanism 5, a cavity adjusting mechanism 6, a pressure adjusting mechanism 7 and a self-weight balancing mechanism 8 are respectively arranged inside the installation frame 1.

[0037] In order to realize the sealing action during the adjustment operation of the cavity adjusting mechanism 6, the sealing mechanism 5 includes a sealing frame 51. The peripheral surfaces of the sealing frame 51 are respectively slidably inserted into the inner walls of the installation frame 1. Arc-shaped sealing grooves 52 and square sealing grooves 53 are respectively formed on the peripheral surfaces of the sealing frame 51. The two square sealing grooves 53 are respectively located on both sides of the arc-shaped sealing groove 52. An arc-shaped sealing ring 54 is fixedly installed on the inner wall of the arc-shaped sealing groove 52, and a square sealing gasket 55 is fixedly installed on the inner wall of the square sealing groove 53. The surfaces of one side of multiple square sealing gaskets 55 and the surface of the arc-shaped sealing ring 54 are respectively slidably inserted into the inner walls of the installation frame 1.

[0038] Specifically, it is implemented as follows. Two sealing frames 51 are respectively arranged on both sides of the middle layer glass 3. Two square sealing gaskets 55 and an arc-shaped sealing ring 54 are installed on the peripheral surfaces of the sealing frames 51, so that they are all pressed against the inner walls of the installation frame 1, and then the peripheral surfaces of the sealing frames 51 are sealed with the inner walls of the installation frame 1. The two square sealing gaskets 55 are respectively located on both sides of the arc-shaped sealing ring 54 to enhance the sealing effect of the sealing frame 51.

[0039] In order to realize the installation operation of the outer layer glass and the inner layer glass 4, insertion limiting grooves 56 are formed on the inner wall of the sealing frame 51. The surfaces of the outer layer glass 2 and the inner layer glass 4 are respectively inserted into the inner walls of the two insertion limiting grooves 56. Insertion holes 57 are formed on the surfaces of the outer layer glass 2 and the inner layer glass 4. Multiple insertion holes 57 are distributed in an annular array. Limiting support rods 58 are slidably inserted into the inner walls of the insertion holes 57. The two ends of multiple limiting support rods 58 are respectively fixedly installed on the inner walls of the insertion limiting grooves 56.

[0040] Specifically, it is implemented as follows. An insertion limiting groove 56 is provided on the inner wall of the sealing frame 51, so as to facilitate the installation of the outer glass 2 and the inner glass 4 inside the insertion limiting groove 56. During the installation of the outer glass and the inner glass 4, a plurality of limiting support rods 58 are also arranged in a circular array on the surfaces of the outer glass and the inner glass 4, so that their arc surfaces are adjusted inside the insertion holes 57 to support and limit the outer glass and the inner glass 4, avoiding the overall pressure of the outer glass and the inner glass 4 being evenly distributed under their own weights and forming an integral body with the sealing frame 51.

[0041] In order to realize the actions of the outer glass 2 and the inner glass 4 moving towards each other or in opposite directions; the cavity adjusting mechanism 6 includes a driving plug 61. The surface of the driving plug 61 is square-shaped. Sliding sealing rings 62 are fixedly installed on the peripheral surfaces of the driving plug 61. A stepped sealing plate 63 is connected to the inner wall of one side of the installation frame body 1 by screws. Driving cavities 64 are provided on the inner walls of one side of the stepped sealing plate 63 and the inner wall of one side of the installation frame body 1. A plurality of driving cavities 64 are arranged in a circular array on the surface of the installation frame body 1. The inside of the driving cavity 64 is slidably inserted with the surface of the sliding sealing ring 62. The inner wall size of the driving cavity 64 is adapted to the size of the driving plug 61.

[0042] Specifically, it is implemented as follows. When the external temperature changes with the weather, the air pressure inside the driving cavity 64 can be adjusted to drive the driving plug 61 to move, so as to adjust the distance between the outer glass and the inner glass 4 and the middle glass 3 to increase or decrease. Because the greater the distance between the glasses, the better the heat insulation performance. This is because the air layer left between the glasses can prevent heat conduction and convection. Therefore, this device can adjust the distance between the middle glass 3 and the outer glass and the inner glass 4 according to the external temperature environment to adjust the heat insulation, enhance the heat preservation effect of the solar greenhouse, and reduce the heat loss while retaining the visible light transmittance. It has good heat insulation performance and heat preservation performance, can significantly reduce the energy consumption inside the greenhouse, and improve the production efficiency and economic benefits.

[0043] In order to connect a plurality of driving cavities 64 into an integral body, connection holes 65 are provided on the inner walls of the plurality of driving cavities 64. Through the connection holes 65, the plurality of driving cavities 64 are fixedly connected. A compression spring 66 is fixedly installed on one side of the driving plug 61. One end of the compression spring 66 is fixedly installed on the inner wall of the driving cavity 64. An installation and maintenance plate 67 is hermetically installed on the inner wall of one side of the driving cavity 64 by sealant.

[0044] Specifically, it is implemented as follows. By setting the connection holes 65, multiple driving chambers 64 are connected. When air pressure enters the interior of one driving chamber 64, under the condition of the connection holes 65, the air pressure circulates inside multiple driving chambers 64, enabling synchronous enhanced driving. When the air pressure increases, while squeezing the driving plug 61 to slide, it also squeezes the compression spring 66 to generate a reverse elastic force. When the air pressure decreases and is less than the directional elastic force of the compression spring 66, the effect of automatically controlling the reverse movement of the driving plug 61 is achieved.

[0045] To adjust the pressure of the driving chamber 64, one side of a mounting and maintenance plate 67 is fixedly connected and communicated with an operation pipe 68. A valve 69 is arranged on the surface of the operation pipe 68. Series holes 610 are opened on the inner wall of the driving chamber 64 inside the stepped sealing plate 63 and the inner wall of the driving chamber 64 inside the mounting frame 1. One end of the series hole 610 corresponds to the feeding end of the operation pipe 68, and the series hole 610 connecting the driving chamber 64 inside the stepped sealing plate 63 and the driving chamber 64 inside the mounting frame 1 is hermetically connected through a sealing pipe.

[0046] Specifically, it is implemented as follows. By using the valve 69 to open, the air pressure of the control air pump enters the interior of the operation pipe 68, enabling the air pressure to synchronously increase and drive inside multiple driving chambers 64. When the adjustment is completed, just close the valve 69. And setting the series holes 610 facilitates the connection of the driving chamber 64 inside the stepped sealing plate 63 and the driving chamber 64 inside the mounting frame 1, achieving the effect of joint air pressure adjustment operation.

[0047] To achieve the action of keeping the pressure in the pressure chamber inside the cavity adjustment mechanism 6 balanced; the pressure adjustment mechanism 7 includes a driving pipe 71 installed on the inner bottom wall of the mounting frame 1 and an adjustment pipe 72 installed on the top end of the mounting frame 1. A first sealing ring gasket 73 is fixedly installed on the inner bottom wall of the driving pipe 71, a first compression spring 74 is fixedly installed on the inner top wall of the driving pipe 71, a first sealing ball 75 is fixedly installed at the bottom end of the first compression spring 74, and the surface of the first sealing ball 75 is pressed against the surface of the first sealing ring gasket 73.

[0048] Specifically, it is implemented as follows. When the distance between the outer glass and the inner layer glass 4 and the middle glass 3 is adjusted to increase or decrease, the air pressure inside will increase or decrease accordingly. When the air pressure inside decreases as the distance increases, an intake pipe is inserted at the bottom of the driving pipe 71, enabling it to push the first sealing ball 75 away from the first sealing ring gasket 73, and adding inert gas to the inside by using the driving pipe 71 to increase the air pressure inside.

[0049] A second sealing ring gasket 76 is fixedly installed on the inner wall of the bottom end of the adjusting pipe 72, and a second compression spring 77 is fixedly installed on the inner wall of the top end of the adjusting pipe 72. The bottom end of the second compression spring 77 is fixedly installed with a second sealing ball 78. The surface of the second sealing ball 78 is pressed against the surface of the second sealing ring gasket 76. The maximum air pressure inside the cavity formed by the surfaces of the two sides of the middle glass 3 and the surfaces of the outer glass 2 and the inner glass 4 is equal to the pressure of the second compression spring 77.

[0050] Specifically, it is implemented as follows. When the distance is reduced, the air pressure of the inert gas inside increases, making the highest air pressure inside greater than the pressure of the second compression spring 77, pushing the second sealing ball 78 away from the second sealing ring gasket 76 so that the inert gas pressure inside flows out, thereby reducing the air pressure effect inside. When this device is used for building a solar greenhouse, it is fixed by the method of pairwise stacking installation, so that the top end of the adjusting pipe 72 and the bottom end of the driving pipe 71 are correspondingly installed using a sealing pipe. When the inert gas pressure inside the lower installation frame 1 increases and flows out from the top end of the adjusting pipe 72 and enters the inside of the driving pipe 71, a linkage adjustment effect is achieved.

[0051] In order to achieve the action of gravity balance of the outer glass 2 and the inner glass 4 in the vertical direction; the self-weight balance mechanism 8 includes connecting crossbars 81. A plurality of connecting crossbars 81 are evenly distributed in a circular array on the surface of the installation frame 1. One end of each of the plurality of connecting crossbars 81 is fixedly installed on the surface of the sealing frame 51, and the other end of each of the connecting crossbars 81 is fixedly installed on the central surface of the driving plug 61, and the connecting crossbars 81 are movably sleeved with compression springs 66.

[0052] Specifically, it is implemented as follows. Through a plurality of connecting crossbars 81 distributed in a circular array, one end of which is connected to the driving plug 61. When a plurality of driving plugs 61 move synchronously to drive a plurality of connecting crossbars 81 to slide, under the limit that the other ends of the plurality of connecting crossbars 81 are fixedly installed on the surface of the sealing frame 51, the sealing frame 51 is synchronously driven to slide, thereby adjusting the distance between the outer glass 2, the inner glass 4 and the middle glass 3. And by using a plurality of connecting crossbars 81 to slide in the horizontal direction and being evenly distributed in a circular array, the gravity of the sealing frame 51 is evenly distributed on the plurality of connecting crossbars 81. Then, when the sealing frame 51 is vertically distributed, the extrusion forces of the arc-shaped sealing rings 54 and the square sealing gaskets 55 around it on the inner wall of the installation frame 1 are consistent, enhancing the sealing performance between them.

[0053] The device is provided with a cavity adjustment mechanism 6 inside the installation frame 1 to adjust the distance between the outer glass 2, the inner glass 4 and the middle glass 3 according to the outdoor ambient temperature, and a self-weight balancing mechanism 8 is provided to achieve the gravity balance of the outer glass 2 and the inner glass 4 on both sides of the middle glass 3, so that the sealing mechanism 5 around it has a strong sealing effect and can be sealed during the sliding adjustment of the sealing frame 51. The pressure adjustment mechanism 7 is provided to automatically adjust according to the air pressure value inside the cavity after the spacing adjustment is completed, so as to avoid the harm of the glass self-explosion caused by the increase or decrease of the internal air pressure, thereby having good heat insulation and thermal insulation performance, which can significantly reduce the energy consumption inside the greenhouse, improve production efficiency and economic benefits, and on the one hand, reduce the installation of a large number of windows taken by the Dutch Venlo glass greenhouse due to ventilation, avoid air leakage caused by the windows due to poor sealing, and reduce the thermal insulation capacity; on the other hand, the light transmittance of the outer glass 2, the middle glass 3 and the inner glass 4 is 10-15% lower than that of ordinary hollow glass, but the thermal resistance value is increased by 5 times, which greatly improves the thermal insulation capacity of the facade.

[0054] Working principle: During the installation operation, first control the inner glass 4 and the corresponding multiple connecting cross bars 81 to be installed, and then install the middle glass 3. After the installation is completed, take the step sealing plate 63 on one side of the installation frame 1 and install it, and then install the outer glass 2.

[0055] When the installation is completed, when the internal insulation effect needs to be adjusted according to the outdoor temperature, the air inlet pipe installed on the surface of the drive tube 71 below the installation frame 1 is driven to control the inert gas to enter the interior of the drive tube 71 to add or reduce air to the cavity. At the same time, the valve 69 is opened to control the air pressure of the air pump to enter the interior of the operating tube 68, so that the air pressure inside the drive cavity 64 is increased or reduced, and then the air pressure is used to push the drive plug 61 to move, driving the sealing frame 51 to move and adjust the spacing. While the spacing is adjusted, the air inside the cavity is reduced or increased. When the maximum internal air pressure is greater than the pressure of the second compression spring 77, the second sealing ball 78 is automatically pushed away from the second sealing ring gasket 76 to perform a pressure relief operation.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
