Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse, and specifically relates to a ventilation structure of a greenhouse. Background Art

[0002] A greenhouse, also known as a hothouse, is a facility for cultivating plants that can transmit light and keep warm (or heat). In seasons when it is not suitable for plant growth, the greenhouse can provide a growth period and increase yields. It is mostly used for cultivating heat-loving vegetables, flowers, forest trees and other plants or seedling raising in low-temperature seasons. Through the principle of "greenhouse effect", the greenhouse creates a suitable environment for crop growth by regulating the indoor temperature in seasons when crops are not suitable for open-field growth, so as to achieve the purpose of crop production and increase crop yields. During the use of the greenhouse, the ventilation structure is particularly important.

[0003] As disclosed in a Chinese patent: a ventilation structure of a greenhouse, application number: CN202320606847.9, which includes a greenhouse body. A ventilation opening is provided on the support frame on one side of the greenhouse body. The ventilation opening is strip-shaped. A protective cover is rotatably provided on the support frame above the outer side of the ventilation opening through a rotating shaft. There are multiple protective covers, and the adjacent protective covers are detachably arranged. The inner side surface of the protective cover is detachably arranged with the support frame. A first motor is provided outside one end of the greenhouse body, and one end of the rotating shaft is driven by the first motor. An air guiding shaft is rotatably arranged on the greenhouse body inside the ventilation opening, and the air guiding shaft is driven by a second motor. The utility model rotates the rotating shaft to drive the protective cover to rotate and unfold outward to ventilate the inside of the greenhouse body. Through the rotation of the air guiding shaft, the conversion of air inside and outside the greenhouse body is increased, making the ventilation effect better.

[0004] However, in the above technical solution, when the ventilation structure of the greenhouse is ventilated, the air inside and outside the greenhouse is converted. However, the air quality outside the greenhouse will change with the change of the external weather. For example, when the weather is hot, in order to reduce the temperature inside the greenhouse, a large amount of ventilation is required. Therefore, the ventilation volume of the ventilation structure needs to be large. When the weather is cold, in order to ensure that the temperature inside the greenhouse will not be too low, a small ventilation volume is required. At present, the ventilation volume of the ventilation structure of the greenhouse is fixed and cannot be adjusted according to the indoor and outdoor temperature and humidity. Summary of the Utility Model

[0005] The main purpose of the present utility model is to provide a ventilation structure for a greenhouse, which can effectively solve the problem that in the background art, when the ventilation structure of the greenhouse conducts ventilation, it converts the air inside and outside the greenhouse, and the air quality outside the greenhouse changes with the external weather. For example, when the weather is hot, in order to reduce the temperature inside the greenhouse, a large amount of ventilation is required, so the ventilation volume of the ventilation structure needs to be large; when the weather is cold, in order to ensure that the temperature inside the greenhouse does not drop too low, a small ventilation volume is required. However, the ventilation volume of the current greenhouse ventilation structure is fixed and cannot be adjusted according to the indoor and outdoor temperature and humidity.

[0006] To achieve the above object, the technical solution adopted by the present utility model is as follows:

[0007] A ventilation structure for a greenhouse, including a base, several rotating grooves are provided on the base, a ventilation groove is provided on one side of the rotating groove, a rotating baffle is provided in the rotating groove, an insect-proof filter screen is fixedly provided in the ventilation groove, a sliding groove is provided on one side of the ventilation groove, an adjusting device is provided in the sliding groove, a first rotating column is provided on the rotating baffle, and a motor is provided at one end of the first rotating column.

[0008] Preferably, the rotating groove is communicated with the ventilation groove, the rotating baffle is rotatably connected to the base through the first rotating column, and the motor is fixedly installed on the base.

[0009] Preferably, the adjusting device includes a device base, and tooth grooves are provided on both sides of the device base.

[0010] Preferably, a gear is meshed on one side of the tooth groove, a second rotating column is provided on the gear, a worm gear is provided at one end of the second rotating column, a worm is meshed on one side of the worm gear, a third rotating column is provided on the worm, and a knob is provided on the third rotating column.

[0011] Preferably, the device base is slidably connected to the base.

[0012] Preferably, one end of the third rotating column rotatably penetrates through the base.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] (1) First, the base of the present utility model is fixedly installed on the greenhouse. Then, when ventilation is required, the first rotating column is rotated by the motor, and the first rotating column drives the rotating baffle, so that the rotating baffle rotates around the first rotating column, releasing the closure of the rotating baffle on the rotating groove. At the same time, during ventilation, the rotating baffle can be used to block rain and snow. Then, the knob is rotated to move the equipment base, and the ventilation area of the ventilation groove is increased or decreased through the equipment base, so that the ventilation volume of the ventilation groove can be adjusted according to the indoor and outdoor temperature and humidity, thereby keeping the indoor temperature and humidity within a suitable range, and blocking mosquitoes through the insect-proof filter screen during ventilation to prevent external mosquitoes from entering the greenhouse through the ventilation groove.
