Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural facilities, and in particular relates to a composite greenhouse gutter. Background Art

[0002] Glass greenhouse is a kind of building widely used in plant cultivation and agricultural production. Because glass greenhouse can control factors such as temperature, humidity, light and carbon dioxide concentration, it is not affected by climate and outdoor temperature and humidity, and provides a suitable and stable environment for plant growth. In any season, glass greenhouse can provide the required heat and light for growing plants, so that plant growth is under artificial control. Therefore, glass greenhouse greatly improves the yield and quality of crops, and thus brings economic benefits to growers.

[0003] Greenhouse gutters are also called greenhouse water tanks. Their function is to collect precipitation from the roof and drain the naturally formed rain and snow water to the ground through height difference drainage to avoid adverse effects such as roof leakage caused by accumulation of liquid. In order to meet the above conditions, the current conventional greenhouse gutters adopt the method of changing the height of the supporting columns under the gutters to make the greenhouse gutters have a specific slope, that is, the first end is high and the tail end is low. However, through long-term use, it is found that there are many disadvantages during this period, such as affecting the overall aesthetics of the greenhouse, the inability of the facilities to bear vertical force, heat loss caused by simple gutter structures, indoor condensation, etc. Utility Model Content

[0004] The purpose of the utility model is to solve one or some defects existing in the above-mentioned prior art and to provide a composite gutter device for a glass greenhouse, which can effectively solve the problems of poor drainage, water accumulation in the gutter and heat loss caused by problems with the material of the greenhouse gutter.

[0005] According to the utility model, a composite greenhouse gutter comprises a gutter body and a U-shaped groove. The gutter body is horizontally fixed on a column, and the U-shaped groove is embedded in the gutter body according to a certain slope. A drainage port is arranged at one end of the gutter body, and the lowest end of the U-shaped groove is close to the drainage port.

[0006] Preferably, the U-shaped groove is formed by connecting a plurality of open grooves end to end.

[0007] In a specific case, a cavity is formed between the bottom surface of the gutter body and the bottom surface of the U-shaped groove. Preferably, the cavity is filled with a heat-insulating material.

[0008] Preferably, the top ends of both side edges of the U-shaped groove are respectively engaged and fixed with both side edges of the gutter body through outwardly turned edges.

[0009] Preferably, the U-shaped groove is embedded in the gutter body at a slope of 0.1-1.0%.

[0010] Compared with the prior art, the composite greenhouse gutter according to the utility model has the following advantages:

[0011] (1) The construction process is reduced. The foundation and structure of the glass greenhouse no longer need to follow the drainage design slope. During construction, the site is flat, the height of the columns is consistent, and the gravity is balanced, which reduces the tedious design and construction process of finding the slope or cutting the columns.

[0012] (2) The drainage efficiency is improved. A composite U-shaped groove is installed on the top of the greenhouse. The slope of the U-shaped groove is used to drain the top of the greenhouse, which greatly improves the drainage efficiency and facilitates maintenance and replacement of wearing parts.

[0013] (3) The thermal insulation performance of the greenhouse is improved. The additional U-shaped groove is isolated from the gutter body, which reduces the heat transfer effect, improves the energy saving of the greenhouse, and brings more economic benefits to growers.

[0014] (4) Simple installation. The whole device is simple and easy to install.

[0015] (5) The overall appearance is smooth and neatly installed. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings.

[0021] See also Figure 1-2 According to the utility model, the composite greenhouse gutter comprises a gutter body 1 and a U-shaped groove 2. The gutter body 1 is horizontally fixed on a column 3, and the U-shaped groove 2 is embedded in the gutter body 1 according to a certain slope. A drain port 4 is provided at one end of the gutter body 1, and the lowest end of the U-shaped groove 2 is close to the drain port 4.

[0022] In a specific case, the gutter body 1 maintains the existing material and design, and the columns 3 supporting the gutter body 1 do not need to be staggered and sloped. The gutter body 1 is parallel to the ground and is arranged horizontally as a whole, which can maintain the overall flatness of the greenhouse and balance the gravity.

[0023] In a specific case, the U-shaped groove 2 is formed by connecting a plurality of open grooves 20 end to end. During installation, the top ends of the two side edges of the U-shaped groove 2 can be respectively fixed to the two side edges of the gutter body 1 by means of the outer flange. The U-shaped groove 2 gradually extends from one end of the gutter body 1 to the other end (drain port 4), and the linear slope only needs to meet the drainage requirements. Preferably, the overall linear slope of the U-shaped groove 2 is 0.1-1.0%. After installation, a cavity 5 is formed between the bottom surface of the gutter body 1 and the bottom surface of the U-shaped groove 2. This cavity 5 can be sealed to play the role of cold bridge insulation, or it can be filled with thermal insulation material as a medium.

[0024] When installing a greenhouse, in order to enable the top of the greenhouse to drain in time, it is usually achieved by slope finding of the foundation or cutting the greenhouse columns in sequence to find the height difference. In practice, due to the limited installation accuracy, the local area of ​​the gutter lies down or bulges, which may cause poor water flow. According to the composite greenhouse gutter of the utility model, a U-shaped groove 2 is installed on the gutter body 1, and a drainage slope is formed by the combined U-shaped groove 2, so that it can drain naturally. Therefore, the foundation or greenhouse columns are not used for slope finding. When the greenhouse is installed, the overall horizontal and vertical structure can be formed, and the appearance is more beautiful and generous.

[0025] In order to improve the smooth drainage of the glass greenhouse in the rainy season, the utility model ensures that the accumulated water is automatically discharged by compounding the inner cavity of the gutter with a U-shaped groove with a linear slope, which can solve the problem of water accumulation in the gutter due to simple installation; at the same time, due to the use of sandwich technology, the internal and external temperatures are better isolated, which can improve the heat loss of the greenhouse and reduce the hidden danger of condensation and burning seedlings in the greenhouse due to large temperature differences.

[0026] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the utility model.
