Description

Technical Field

[0001] The utility model relates to the technical field of indoor and outdoor ventilation, and particularly relates to a ventilation structure for a glass greenhouse. Background Art

[0002] A glass greenhouse refers to a greenhouse with glass as the lighting material and belongs to a type of greenhouse. Among cultivation facilities, the glass greenhouse, as a form with the longest service life, is suitable for use in various regions and under various climatic conditions. Its area and usage method can be freely adjusted by the greenhouse owner. The smallest one is for courtyard leisure, with a large span of up to more than ten meters and a bay width of up to more than 10 meters, and the intelligent level can reach one-key control. Although a glass greenhouse is a cultivation facility mainly for plant cultivation, it is also a building and needs to have both aesthetic appearance.

[0003] Ventilation and air change of the glass greenhouse are one of its basic functions. The main purpose is to remove the waste heat and moisture in the greenhouse, adjust the air composition in the greenhouse, remove harmful gases, and make the environmental temperature, humidity, air and other conditions in the greenhouse meet the requirements for plant growth. The existing ventilation methods mainly include natural ventilation and forced ventilation. No matter which ventilation method is used, air exhaust openings and air inlet openings need to be set on the glass greenhouse. For most greenhouses, air exhaust openings and air inlet openings are set around the glass greenhouse. This layout method will, on the one hand, affect the appearance of the entire glass greenhouse, damage the integrity of the glass curtain wall, and have low aesthetic appearance; on the other hand, the speed and effect of ventilation and air change are also not good, and there is more energy loss. Summary of the Invention

[0004] The purpose of the utility model is to provide a ventilation structure for a glass greenhouse aiming at the problems existing in the prior art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A ventilation structure for a glass greenhouse includes an air exhaust channel arranged on the top and / or upper side wall of the glass greenhouse. A top-opening window that can be opened and closed is arranged in the air exhaust channel. A fan is arranged inside the glass greenhouse corresponding to the air exhaust channel. An air inlet opening is arranged on the inner wall of the glass greenhouse, and a side-opening window that can be opened and closed is arranged at the air inlet opening. The air inlet opening is located at the duct of the wet curtain in the glass greenhouse.

[0007] This ventilation structure of the glass greenhouse can more effectively control the temperature and air circulation in the entire glass greenhouse by improving the positions and layout forms of the exhaust channels and the air inlets, which is conducive to maintaining the temperature in the glass greenhouse within the temperature range required by plants. Moreover, the overall shape of the glass greenhouse is more beautiful. Especially when all the exhaust channels are arranged at the top of the glass greenhouse, there are no obvious visible exhaust channels and windows around the glass greenhouse.

[0008] The exhaust channels on the greenhouse roof are vertically arranged, and the top-opening windows installed therein play the roles of exhausting and ventilating as well as blocking rainwater during the opening and closing processes, preventing rainwater from flowing into the room through the exhaust channels.

[0009] In this ventilation system of the glass greenhouse, the exhaust openings are placed at the top and are equipped with chimney devices, which can effectively utilize the chimney effect of hot air rising naturally due to its low density to improve the ventilation effect.

[0010] The fans are arranged below the exhaust channels and are at a certain distance from the exhaust channels. Through such an arrangement, the Bernoulli effect can be formed here, thereby amplifying the air volume of the fans, which is conducive to rapid exhaust and ventilation.

[0011] The air inlets are arranged at the ducts where the wet curtains are installed. On the one hand, when considering the incoming air, the relatively hot air can be cooled by passing through the wet curtains before entering the interior of the glass greenhouse. On the other hand, due to the shielding of the ducts and wet curtains, there are no obvious visible air inlets outside the glass greenhouse, which improves the aesthetic degree of the entire greenhouse and can also make full use of the space at the ducts. An air filtration device (filter screen) and an insect removal device are also installed in the ducts, which can prevent external polluted air, sundries, insects, etc. from entering the greenhouse during the incoming air process.

[0012] Furthermore, the exhaust channels are transparent channels, such as glass channels or transparent channels made of acrylic materials, which can avoid the exhaust channels blocking sunlight; the exhaust channels extend beyond the roof of the glass greenhouse and are located at the highest point of the building.

[0013] Furthermore, the glass channels are enclosed by multiple pieces of single-layer laminated tempered glass, and the thickness of the interlayer of the single-layer laminated tempered glass is not less than 0.76 mm.

[0014] Furthermore, the roof of the glass greenhouse is a wavy structure with undulations, and the exhaust channels are arranged on the inclined surfaces or peaks at the crests of the wavy structure.

[0015] Furthermore, the exhaust channels are arranged at intervals along the length direction of the roof of the glass greenhouse, and the distance between adjacent exhaust channels is 500 - 5000 mm, and multiple rows of exhaust channels are arranged along the length direction.

[0016] Furthermore, a drain trough is provided at the lowest point where the roof of the glass greenhouse contacts the exhaust air duct, which can drain the rainwater in the exhaust air duct to avoid water accumulation and prevent rainwater from leaking into the interior.

[0017] Furthermore, the fan is installed below the roof of the glass greenhouse through a hanging bracket.

[0018] Furthermore, an anemometer is also provided in the exhaust air duct to be able to detect the wind speed of the exhaust air in real time.

[0019] Furthermore, a culvert higher than the ground is provided below the outer side wall of the glass greenhouse. A wet curtain is provided in the culvert. The air inlet is arranged directly opposite the wet curtain, and the side opening window opens towards the culvert.

[0020] Furthermore, both the top opening window and the side opening window are automatic glass windows, such as electric glass windows, for automated control.

[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows: 1. The ventilation structure of this glass greenhouse improves the positions and layout forms of the exhaust air duct and the air inlet, and utilizes the chimney effect of hot air rising to be able to more effectively control the temperature and air circulation in the entire glass greenhouse, which is beneficial to keeping the temperature in the glass greenhouse within the temperature range required by plants. Moreover, the overall shape of the glass greenhouse is more beautiful. Especially when all the exhaust air ducts are arranged at the top of the glass greenhouse, there are no obvious visible exhaust air ducts and windows around the glass greenhouse; 2. The exhaust air duct on the roof is vertically arranged, and the top opening window arranged therein plays both the role of exhausting and ventilating and the role of blocking rainwater during the opening and closing process, preventing rainwater from flowing into the interior from the exhaust air duct; 3. The fan is arranged below the exhaust air duct and has a certain distance from the exhaust air duct. Through such an arrangement, the Bernoulli effect can be formed here, thereby amplifying the air volume of the fan and being beneficial to rapid exhaust and ventilation; 4. The air inlet is arranged at the culvert where the wet curtain is arranged. On the one hand, it is considered that when the air enters, the hotter air can be cooled by passing through the wet curtain before entering the interior of the glass greenhouse. On the other hand, by the shielding of the culvert and the wet curtain, there is no obvious visible air inlet outside the glass greenhouse, improving the aesthetic degree of the entire greenhouse. At the same time, the space at the culvert can be fully utilized. The existence of the culvert enables the window to open towards the culvert without occupying the greenhouse space, and an air filtering device and a pest control device can be arranged in the culvert; 5. The glass channel is made of single-layer laminated tempered glass, which can avoid blocking sunlight due to the arrangement of the exhaust air duct, and has better appearance consistency and aesthetics.

[0030] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor conditions belong to the scope of protection of the present utility model.

[0031] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] Such as Figures 1 to 6As shown in the figure, a ventilation structure for a glass greenhouse includes an exhaust duct 2 provided at the top of the glass greenhouse 1. An opening and closing top window 3 is provided in the exhaust duct 2. A fan is provided inside the glass greenhouse 1 corresponding to the exhaust duct 2. An air inlet 7 is provided on the inner wall of the glass greenhouse 1. A side window 701 that can be opened and closed is provided at the air inlet 7. The air inlet 7 is located at the duct 5 of the wet curtain 6 in the glass greenhouse 1.

[0033] By improving the positions and layout forms of the exhaust duct 2 and the air inlet 7, this ventilation structure for the glass greenhouse can more effectively control the temperature and air circulation inside the entire glass greenhouse 1, which is beneficial to keeping the temperature inside the glass greenhouse 1 within the temperature range required by plants. Moreover, the overall shape of the glass greenhouse 1 is more beautiful. Especially when all the exhaust ducts 2 are provided at the top of the glass greenhouse 1, there are no obvious visible exhaust ducts and windows around the glass greenhouse 1. The four sides of the glass greenhouse 1 are directly built with full-size curtain walls, reducing the difficulty of opening windows and ducts on the curtain walls.

[0034] The exhaust duct 2 on the roof of the greenhouse is vertically arranged. The top window 3 provided therein plays both the role of exhausting air and blocking rainwater during the opening and closing process, preventing rainwater from flowing into the room through the exhaust duct.

[0035] The fan is arranged below the exhaust duct and is at a certain distance from the exhaust duct. Through such an arrangement, the Bernoulli effect can be formed here, thereby amplifying the air volume of the fan and being beneficial to rapid exhaust ventilation.

[0036] The air inlet 7 is provided at the duct 5 where the wet curtain 6 is arranged. On the one hand, it is considered that when the air enters, the relatively hot air can be cooled by the wet curtain 6 before entering the interior of the glass greenhouse 1. On the other hand, by the shielding of the duct 5 and the wet curtain 6, there is no obvious visible air inlet outside the glass greenhouse 1, improving the aesthetics of the entire greenhouse, and at the same time, the space at the duct can be fully utilized.

[0037] The exhaust duct 2 and the air inlet 7 cooperate with each other. The low-temperature air flow enters from the bottom of the glass greenhouse, and the high-temperature gas is discharged from the top of the glass greenhouse, which conforms to the principle of air flow, that is, hot air rises and cold air sinks. Through such an arrangement, it is beneficial to ventilation and temperature adjustment. Both the top window and the side window can be independently controlled and opened and closed as needed.

[0038] Furthermore, the roof of the glass greenhouse 1 is a wavy structure with undulations. The exhaust duct 2 is arranged on the inclined surface at the peak of the wavy structure. A drain trough is provided at the lowest point where the roof of the glass greenhouse 1 contacts the exhaust duct 2.

[0039] For the roof of the glass greenhouse 1, it is designed as a wavy structure with undulations. On the one hand, it is for aesthetic purposes, and on the other hand, it is specifically arranged to cooperate with the sunshade system to adjust the sunlight indoors; in this structure, the exhaust duct 2 is preferably arranged at the wave crest, the bottom surface of the exhaust duct 2 is installed on the glass of the roof in an inclined manner, and the top opening window is located at the position of the inclined surface and can be flipped upwards to open.

[0040] At the lowest point of the joint between the bottom of the exhaust duct 2 and the roof surface, a drainage trough is provided, which can drain the rainwater in the exhaust duct to avoid water accumulation and prevent rainwater from leaking into the room.

[0041] In some embodiments, as Figure 5 shown, the exhaust duct 2 can be arranged at the peak position of the wave crest of the roof of the greenhouse, and the top opening window is opened from the middle to both sides.

[0042] Furthermore, the exhaust ducts 2 are arranged at intervals along the length direction of the roof of the glass greenhouse 1, the distance between adjacent exhaust ducts 2 is 500 - 5000 mm, and multiple rows of exhaust ducts 2 are arranged along the length direction.

[0043] Multiple rows of the exhaust ducts can be respectively arranged on the inclined surfaces on both sides of adjacent wave crests, and each row of the exhaust ducts can be arranged at intervals of 600 - 700 mm, 1100 - 1200 mm, 2200 - 2300 mm, etc. according to the position and the needs of the roof structure.

[0044] The cross-sectional size of the air outlet of the exhaust duct 2 is 800 * 800 mm, and some of the exhaust ducts can also be used as roof inspection openings for maintaining the roof.

[0045] Furthermore, an anemometer is also provided in the exhaust duct 2 to be able to detect the wind speed of the exhaust air in real time.

[0046] Furthermore, the fan is installed below the roof of the glass greenhouse through a hanging bracket, and the hanging bracket is fixedly connected to the steel skeleton system of the glass greenhouse.

[0047] Furthermore, a duct 5 higher than the ground is provided below the outer side wall of the glass greenhouse 1, a wet curtain 6 is provided in the duct 5, the air inlet 7 is arranged directly opposite the wet curtain 6, and the side opening window 701 opens towards the duct 5.

[0048] The outer periphery of the glass greenhouse 1 is provided with a heat-insulating soil slope protection 4, which is conducive to improving the foundation stability of the entire glass greenhouse. Green plants are also planted on these slope protection structures to enhance the external aesthetics of the entire glass greenhouse. The duct 5 is arranged at this position, which can not only keep it at a low position, facilitating the wet curtain to play a better role, but also avoid setting a wet curtain system on the glass curtain wall. The duct 5 has a relatively large space, which can accommodate the wet curtain 6 and also allow the side window 701 to open outward. The reason for not opening inward is that there is a steel keel framework system of the glass curtain wall on the indoor side to avoid movement interference during inward opening. Secondly, inward opening will occupy the space of the greenhouse.

[0049] Furthermore, the exhaust duct 2 is a glass duct, and the exhaust duct 2 extends beyond the roof of the glass greenhouse 1; the glass duct is enclosed by multiple pieces of single-layer laminated tempered glass, and the thickness of the interlayer of the single-layer laminated tempered glass is not less than 0.76 mm.

[0050] Using single-layer laminated tempered glass to make the glass duct can avoid blocking sunlight due to the setting of the exhaust duct, and using the same type of building materials as the glass greenhouse also makes its appearance consistency and aesthetics better.

[0051] Furthermore, the top window 3 and the side window 701 are both electric glass windows and can be electrically controlled through a controller for the automatic adjustment of the glass greenhouse.

[0052] In some embodiments, as Figure 7 shown, a hollowed-out frame 8 extends from the peripheral wall of the exhaust duct 2 at the top. A swingable baffle 10 is suspended by a thin string 9 on each surface of the frame 8. When the wind blows from the direction of the baffle 10, these baffles 10 will stand up, and a negative pressure (Bernoulli effect) will be formed on the back of the baffle 10 by the wind speed. This negative pressure will drive the airflow in the duct to move upward, thereby being able to improve the exhaust speed and efficiency of the exhaust duct.

[0053] Specifically, the baffle 10 is connected to the lower part of the frame 8 through a rotating shaft. Ring holes are provided at the upper part of the frame 8 and the upper two corners of the baffle 10, and the thin string 9 is connected through the ring holes.

[0054] A control method for the ventilation structure of this glass greenhouse is as follows:

[0055] The most suitable temperature range Tmin - Tmax in the glass greenhouse set according to different crops; let the real-time temperature in the glass greenhouse be T, and the outdoor temperature be T0;

[0056] Judge whether T is greater than Tmax. If so, judge whether the top opening window and the side opening window are open. If they are open, turn on the wet curtain and the fan. If they are not open, open the top opening window and the side opening window.

[0057] Judge whether T is greater than Tmax. If not, continue to judge whether T is greater than Tmin. If so, judge whether the wet curtain and the fan are open. If they are open, turn off the wet curtain and the fan.

[0058] If it is judged that T is less than Tmin, if so, judge whether the wet curtain and the fan are open. If they are open, turn off the wet curtain and the fan, and close the top opening window and the side opening window.

[0059] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
