Abstract
Description
Technical Field
[0001] This utility model relates to the field of greenhouse technology, and more specifically, to a semi-enclosed greenhouse climate chamber. Background Technology
[0002] Current research on semi-enclosed greenhouses is limited. Most greenhouse cooling systems utilize evaporative cooling pads and fans, but this method limits the distance between the evaporative pads and fans to no more than 50 meters. Beyond 50 meters, the cooling effect significantly decreases, resulting in noticeable cooling failure zones in greenhouses exceeding this length. Furthermore, conventional axial flow fans cannot meet the airflow penetration requirements of large-span greenhouses. This limits the length of greenhouses to 50 meters, while planting greenhouses often exceed this length, meaning the evaporative cooling pads and fans are not fully utilized.
[0003] In response to the above problems, how to solve the long-distance transportation of greenhouse climate regulation equipment has become an urgent technical problem. Utility Model Content
[0004] In view of the above-mentioned technical problems in related technologies, this utility model proposes a semi-enclosed greenhouse climate chamber, which can overcome the above-mentioned shortcomings of the prior art.
[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:
[0006] A semi-enclosed greenhouse climate chamber includes a climate chamber body located inside the greenhouse. A vertical lift window is provided in the middle of the side of the climate chamber body away from the greenhouse. A corresponding wet curtain is provided inside the vertical lift window. The upper and lower ends of the wet curtain are connected to the upper and lower ends of the vertical lift window through corresponding hot-dip galvanized plate seals. A top-opening window is provided at the top of the climate chamber body. Several positive pressure fans are provided at the bottom of the climate chamber body near the greenhouse. The positive pressure fans are connected to a corresponding long ventilation duct located directly below the cultivation trough inside the greenhouse.
[0007] Furthermore, the climate chamber body is 2-3 meters wide and 4-5 meters high.
[0008] Furthermore, the climate chamber body is enclosed by glass.
[0009] Furthermore, the top-hinged window is a continuous window, and it is opened and closed by a drive motor that rotates a gear rack.
[0010] Furthermore, the vertical lifting window is opened and closed by driving the gear rack two to rotate via the second drive motor.
[0011] Furthermore, the evaporative cooling pad is driven by an evaporative cooling pad water supply system.
[0012] Furthermore, an insect-proof net is provided between the vertical lifting window and the wet curtain.
[0013] The beneficial effects of this invention are as follows: This invention establishes a climate chamber on one side of the greenhouse, with a vertically lifting window on the side of the climate chamber away from the greenhouse. A top-hinged window is located at the top of the climate chamber, and a wet curtain is installed inside the vertically lifting window. A positive pressure fan is connected to a long ventilation duct. When the positive pressure fan is operating, the top-hinged window of the climate chamber and the vertically lifting window of the wet curtain are closed. The heating and cooling loads are transported to the positive pressure fan through pipes and then to the crop roots through the ventilation duct, thus achieving climate regulation. When the greenhouse needs increased humidity, the top-hinged window of the climate chamber and the vertically lifting window of the wet curtain are closed, the wet curtain water supply system operates, and the positive pressure fan delivers humidity into the greenhouse. This invention solves the problem of cooling failure during long-distance transport of greenhouse climate control materials, effectively ensuring climate regulation, humidification, and ventilation in the greenhouse, making it highly practical.

A vertical lifting window 2 is provided in the middle of the side of the climate chamber body 1 away from the greenhouse. A corresponding wet curtain 3 is provided inside the vertical lifting window 2. The upper and lower ends of the wet curtain 3 are connected to the upper and lower ends of the vertical lifting window 2 through corresponding hot-dip galvanized plate sealing parts 8.

[0027] Furthermore, the wet curtain 3 is driven by the wet curtain water supply system.
[0028] Furthermore, an insect-proof net 7 is provided between the vertical lifting window 2 and the wet curtain 3.
[0029] To facilitate understanding of the above-mentioned technical solutions of this utility model, the following detailed description of the above-mentioned technical solutions of this utility model is provided through specific usage methods.
[0030] In practical use, the semi-enclosed greenhouse climate chamber described in this utility model solves the problem of long-distance transportation for greenhouse climate regulation.
[0031] The system features a semi-enclosed climate chamber, a sealed glass enclosure 2-3 meters wide and 4-5 meters high, located inside one side of the greenhouse. A wet curtain is installed outside the climate chamber for evaporative cooling and humidity control. A vertical lift window, capable of being fully opened, provides high ventilation volume and efficiency. A top-hinged window, using rack and pinion drive, is located at the top of the climate chamber and operates as a continuous window in conjunction with the wet curtain window.
[0032] Positive pressure fans are installed at the bottom of the climate chamber on the side closest to the greenhouse, spaced 1.5-2 meters apart. The power of the positive pressure fans is generally 2.2-3KW, with an air volume of 10,000m3 / h. Each positive pressure fan is connected to a long air duct with a diameter of 500-1000mm and a length of up to 150 meters, which can transport the heat and cold from the climate chamber to the end of the cultivation trough and the roots of the crops.
[0033] The upper and lower ends of the wet curtain are connected to the upper and lower ends of the vertical lifting window through corresponding hot-dip galvanized steel plate seals. The hot-dip galvanized steel plate seal at the lower end is Z-shaped, and its bottom is fixed to the lower frame of the wet curtain with rivets.
[0034] The positive pressure fan is installed at the bottom of the semi-enclosed area's facade; the ventilation duct is a baghouse duct installed directly below the cultivation trough. When the positive pressure fan is working, the top-hinged window of the climate chamber is closed, the vertical lifting window of the evaporative cooling pad is closed, and the climate chamber is a sealed environment. The heating and cooling loads are transported to the positive pressure fan through pipes, and then to the crop roots through the ventilation duct, thereby achieving the climate regulation function.
[0035] When the greenhouse needs to increase humidity, the top flip-up window of the climate chamber closes, the vertical lifting window of the wet curtain closes, the wet curtain water supply system works, and the positive pressure fan runs to deliver humidity into the greenhouse.
[0036] When the positive pressure fan stops working, the top flip-up window and the vertical window of the wet curtain can be opened to ventilate the climate chamber. Alternatively, the positive pressure fan can be run and the top flip-up window closed for forced ventilation.
[0037] In summary, by utilizing the above-mentioned technical solution of this utility model, a climate chamber is set up on one side of the greenhouse, with a vertically lifting window installed on the side of the climate chamber away from the greenhouse. A top-hinged window is installed on the top of the climate chamber, and a wet curtain is installed inside the vertically lifting window. A positive pressure fan is connected to a long ventilation duct. When the positive pressure fan is working, the top-hinged window of the climate chamber and the vertically lifting window of the wet curtain are closed. The cold and heat loads are transported to the positive pressure fan through pipes and then to the crop roots through the ventilation duct, thereby achieving the climate regulation function. When the greenhouse needs to increase humidity, the top-hinged window of the climate chamber and the vertically lifting window of the wet curtain are closed, the wet curtain water supply system is activated, and the positive pressure fan operates to deliver humidity into the greenhouse. This utility model solves the problem of cooling failure during long-distance transportation of greenhouse climate regulation, effectively ensuring the climate regulation, humidification, and ventilation of the greenhouse, and has great practicality.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
