Description

Technical Field

[0001] The utility model belongs to the technical field of solar greenhouses, in particular to a condensed water collecting device on the roof of a solar greenhouse. Background Art

[0002] Solar greenhouses in cold regions generally include a rear wall, a left wall, a right wall, and a front foundation. Several arc-shaped arch beams are set at equal intervals between the rear wall and the front foundation, and a transparent plastic film is covered on the arc-shaped arch beams to form a roof. In order to adjust the temperature and humidity inside the greenhouse according to the air temperature, an upper wind window is set at the rear of the roof and a lower wind window is set at the front of the roof.

[0003] When the temperature outside the greenhouse is below zero all day, in order to preserve the heat inside the greenhouse, ventilation is not allowed during this period. Due to the large temperature difference between indoor and outdoor, indoor moisture cannot be discharged, and condensation will form on the inside of the greenhouse film. In order to prevent condensation from dripping onto the plants planted in the greenhouse, damaging the leaves and spreading diseases, drip-free film is now commonly used. The problem with using drip-free film is that the condensation formed on the inside of the greenhouse film will flow along the greenhouse film to the front of the greenhouse, and finally a large amount of condensation will flow into the soil in the front of the greenhouse. The temperature in the front of the greenhouse is originally low, and with a large amount of condensation water for irrigation, the ground temperature in front of the greenhouse is low, which affects the growth of plants in the front of the greenhouse, and the growth of plants in the greenhouse is inconsistent. In addition, there are pathogens in the condensation water, and the condensation water is poured into the soil inside the greenhouse, which is also likely to cause the spread of plant diseases. Utility Model Content

[0004] The utility model aims to solve the problems existing in the prior art and provides a condensation water collection device for the roof of a solar greenhouse, which can collect the condensation water formed in the greenhouse film and discharge it outside the solar greenhouse to prevent the condensation water from falling into the indoor soil, causing the ground temperature to drop and spreading diseases.

[0005] The purpose of the utility model is achieved as follows: a condensed water collection device for the roof of a solar greenhouse, which includes a greenhouse film covered on a plurality of arc-shaped arch beams, the greenhouse film is a drip-free film, a lower film pressing rod and an upper film pressing rod are arranged on the upper part of the arc-shaped arch beam at a height of 80-120 cm from the ground in the front part of the solar greenhouse, the lower film pressing rod presses the greenhouse film onto the arc-shaped arch beam outside the greenhouse film, the upper film pressing rod is inside the greenhouse film, the upper film pressing rod pulls the greenhouse film from the lower part of the lower film pressing rod and covers the outer part of the lower film pressing rod, the upper film pressing rod presses the arc-shaped arch beam on the upper part of the lower film pressing rod, and the greenhouse film covered on the outer part of the lower film pressing rod forms an arc-shaped dripping part; a water receiving trough is arranged directly below the arc-shaped dripping part, the bottom of the water receiving trough is connected to a drain pipe, and the lower end of the drain pipe is connected to a water receiving bucket.

[0006] Preferably, film pressing rod connecting pieces for connecting the lower film pressing rod and the upper film pressing rod are provided at both ends of the lower film pressing rod and the upper film pressing rod.

[0007] Preferably, the film pressing rod connecting piece is composed of a film rod connecting plate and a wall connecting plate formed by bending a steel plate 90°, the film rod connecting plate is provided with a waist hole connecting the lower film pressing rod and the upper film pressing rod, and the wall connecting plate is provided with a wall screw hole connecting the wall.

[0008] Preferably, the water receiving trough is connected to a plurality of arc-shaped arch beams via a trough connector.

[0009] Preferably, the sink connector includes a sink connecting part and an arch beam connecting part stamped from steel plates, the sink connecting part includes an arc-shaped plate covering the lower part of the water sink and a sink hook clamping the sink edge, and the arch beam connecting part is a flat plate structure provided with arch beam screw holes.

[0011] Preferably, the upper film pressing rod is a round solid rod or a round hollow rod with an outer diameter of 1-5 cm.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] (1) In winter in northern my country, when the temperature outside the greenhouse is below zero all day long, the greenhouse cannot be ventilated during this period in order to preserve the heat inside the greenhouse. Due to the large temperature difference between indoor and outdoor, the indoor moisture cannot be discharged, and condensation will form on the inside of the greenhouse film. Since the greenhouse film is a drip-free film, the condensation will flow forward along the curved greenhouse film with a low front and a high back. When the condensation flows to the curved drip part, it will gather into water droplets and fall into the water receiving trough. The condensation water gathered in the water receiving trough flows into the water receiving bucket through the drain pipe. After the bucket is filled with water, the water is manually discharged outside the greenhouse, effectively preventing the condensation water from falling into the indoor soil, causing the ground temperature to drop and the spread of diseases.

[0014] (2) The utility model does not need to install an electric condensation dehumidification device inside the greenhouse, which saves equipment investment and electricity costs and improves the planting efficiency of the solar greenhouse.

[0015] (3) The utility model has a simple and reasonable structure, is easy to install, and has low cost, and can be widely promoted and applied. BRIEF DESCRIPTION OF THE DRAWINGS
