Description

Greenhouse Column Drainage Structure

technical field

The utility model relates to a drainage facility for a greenhouse, in particular to a drainage structure utilizing a gable column in the greenhouse.

Background technique

Green house, also known as greenhouse, can transmit light, keep warm (or warm), and is used to cultivate plants. In seasons that are not suitable for plant growth, it can provide a growth period and increase production. It is mostly used for temperature-loving vegetables in low-temperature seasons , Flowers, forest trees and other plant cultivation or nursery. There are many types of greenhouses, which can be divided into many types according to different roof truss materials, lighting materials, shapes and heating conditions, such as glass greenhouses, plastic greenhouses; single-span greenhouses, multi-span greenhouses; single-roof greenhouses, double-roof greenhouses; Heated greenhouse, unheated greenhouse, etc. The greenhouse structure should be sealed and insulated, but it should be convenient for ventilation and cooling. Modern greenhouses have equipment to control temperature, humidity, light and other conditions, and use computer automatic control to create the best environmental conditions required by plants.

Chinese Patent Application No. 200810043656.6 discloses a structure for falling water in a greenhouse, which consists of a drainage gutter outside the greenhouse and a hollow column in the greenhouse. In the drainage channel, the rainwater flows into the column from the drainage gutter and is discharged, which can save the use of PVC drainage risers and save resources. However, if the rainfall is heavy, the connection between the drainage gutter and the column is prone to water accumulation and overflow.

Utility model content

The purpose of the utility model is to provide a greenhouse column drainage structure to solve the problem of water overflowing at the junction of the drainage gutter and the column when the rainfall is too heavy.

The technical scheme that the utility model adopts for solving its technical problem is,

The column drainage structure of the greenhouse, including the drainage gutter outside the greenhouse and the hollow column inside the greenhouse. The drainage gutter is provided with a drain, and an overflow device that can accommodate excessive rainwater is connected below the drain opening. The overflow device has a large capacity The lower end of the overflow device is connected to the column, and the lower part of the column is provided with a drainage pipe. The rainwater in the drainage gutter enters the column through the overflow device and is finally discharged through the drainage pipe.

The upper part of the overflow is provided with a connecting plate, which is attached to the drainage gutter, and the connecting plate is provided with a cut hole consistent with the water outlet on the drainage gutter, and the lower part of the overflow is provided with a joint, which is inserted into the column , fit closely with the inner wall of the column.

The connection plate is provided with a connection hole for connecting the drainage gutter, and the joint is provided with a connection hole for connecting the column.

The beneficial effect of the utility model is that an overflow device is installed between the drainage gutter and the column. If the rainfall is too heavy and the column has no time to discharge all the water, the overflow device can accommodate this part of the rainwater to avoid water leakage caused by overflowing rainwater.

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

As shown in Figure 1 and Figure 2, the greenhouse column drainage structure provided by the utility model includes a drainage gutter 100 outside the greenhouse and a hollow column 300 in the greenhouse. Below 110 is connected overflow device 200 which can accommodate excessive rainwater. The overflow device 200 is a large-capacity container. The overflow 200 enters the column 300 and finally exits through the drain pipe 310 .

The upper part of the overflow device 200 is provided with a connecting plate 210, which is attached to the bottom of the drainage gutter 100. The connecting plate 210 is provided with a cut hole 211 consistent with the water outlet on the drainage gutter, and the lower part of the overflow device 200 is provided There is a joint 220 , which is inserted into the column 300 and fits closely with the inner wall of the column 300 .

The connection plate 210 is provided with a connection hole 212 for connecting the drainage gutter 100, and the joint 220 is provided with a connection hole 221 for connecting the column 300.

The greenhouse column drainage structure provided by the utility model is equipped with an overflow device between the drainage gutter and the column. If the rainfall is too large, the column will not have time to discharge all the water, and the overflow device can accommodate this part of the rainwater to avoid water leakage caused by overflowing rainwater.
