Description

Technical Field

[0001] The utility model relates to the technical field of planting, and in particular to a greenhouse ventilation device based on information control. Background Art

[0002] Greenhouses are a type of equipment widely used in the planting industry. They are set up on farmland and use rigid supports to erect high-molecular polymer films to isolate the farmland from the outside environment. Since high-molecular polymer films have thermal insulation properties, after the farmland is covered with greenhouses, the temperature in the greenhouse can change slowly, preventing crops from being damaged due to excessive changes in the external temperature. In order to keep the temperature, oxygen content, humidity and other conditions in the greenhouse within the most suitable range for crop growth for a long time, ventilation devices are needed to exchange the air in the greenhouse with the outside air, and to introduce cold air when the temperature in the greenhouse is too high. Through information control equipment, planting personnel can remotely monitor the temperature conditions of multiple greenhouses and remotely open or close ventilation devices, which greatly reduces the labor intensity of planting personnel and effectively ensures the growth efficiency of plants in the greenhouse.

[0003] Although the above-mentioned existing technology can solve the corresponding technical problems, it still has certain defects: the existing ventilation device is usually equipped with a filter cover at the air inlet to isolate debris in the air. If the air quality at the location of the greenhouse is poor and there are more particulate matter and impurities in the air, after a period of use, it is easy to cause a large amount of dust and debris to adhere to the filter cover of the ventilation device, and the dust and debris on the filter cover will block the through holes on the filter cover, greatly reducing the air intake efficiency of the ventilation device, making it difficult to keep the environment in the greenhouse stable, affecting the growth of plants. Utility Model Content

[0004] The utility model aims to provide a greenhouse ventilation device based on information control which is not easy to be blocked and has a long cleaning cycle in view of the defects and shortcomings of the prior art.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a greenhouse ventilation device based on information control, including an air intake main unit and a ventilation pipe arranged on one side of the air intake main unit and extending into the greenhouse, the air intake main unit includes an air intake shell connected to the ventilation pipe on one side and an exhaust fan arranged in the air intake shell, the inner wall of the air intake shell is detachably provided with a filter, the top of the filter penetrates the air intake shell and extends upward, the inner wall of the air intake shell is located on one side of the filter and is also provided with a rotating cleaning block that can contact the filter, the airflow entering drives the rotating cleaning block to rotate, and contacts the filter to clean the attachments on the surface of the filter.

[0006] A further improvement is that a mounting bracket is also provided at the bottom of the air intake main unit.

[0007] A further improvement is that an information antenna is also penetrated through the air intake shell, and the information antenna is electrically connected to the air extractor.

[0008] A further improvement is that the rotating cleaning block includes an inner core fixedly arranged on the inner wall of the air intake shell and a rotating ring movably engaged with the outer wall of the inner core, and the outer wall of the rotating ring is provided with a plurality of arc-shaped cleaning pieces whose ends can contact the filter.

[0009] A further improvement is that a plurality of balls are arranged between the outer wall of the inner core and the inner wall of the rotating circle.

[0010] A further improvement is that the outer wall of the rotating circle is also provided with a plurality of fan blades.

[0011] A further improvement is that the arc-shaped cleaning piece includes an arc-shaped wind blade arranged on the outer wall of the rotating circle and a contact head arranged at the end of the arc-shaped wind blade and capable of contacting the filter screen.

[0012] A further improvement is that: the contact head is provided with a plurality of cleaning whiskers.

[0013] A further improvement is that an elastic stretch strip is embedded in the middle section of the arc-shaped wind blade.

[0014] A further improvement is that a plurality of wind resistance grooves are provided on the inner arc surface of the arc-shaped wind blade.

[0015] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: when the utility model draws in external air, the rotating cleaning block is driven to rotate by the flowing gas at the same time, and then as the rotating cleaning block rotates, multiple arc-shaped cleaning pieces drive the contact head to contact and collide with the filter, and scrape the surface of the filter, thereby shaking off the attachments on the surface of the filter, and effectively avoiding the filter being clogged by a large number of attachments after long-term use, greatly extending the cleaning cycle, effectively ensuring the air intake effect, and keeping the environment in the greenhouse stable.

At the same time, the air is filtered by the filter 12, and enters the ventilation pipe 2 and is transported to the greenhouse, so that the temperature and oxygen content in the greenhouse meet the conditions for plant growth. When the air enters, the flowing airflow simultaneously impacts the inner arc of the arc-shaped wind blade 31, thereby causing the arc-shaped wind blade 31 to rotate. The power drives the outer rotating circle 22 to rotate. As the rotation progresses, the contact head 33 on the top of the arc-shaped wind blade 31 periodically contacts the surface of the filter 12, and scrapes the attachments on the surface of the filter 12 during the contact, and at the same time hits the filter 12 to vibrate it, loosening the attachments, and causing the attachments to fall off with the impact of repeated vibrations and airflow, thereby effectively preventing the filter from being clogged by a large number of attachments after long-term use, greatly extending the cleaning cycle, effectively ensuring the air intake effect, and keeping the environment in the greenhouse stable.

In this embodiment, six blades are provided, which is beneficial to increase the rotation thrust when the airflow passes through, so that the rotating circle 22 rotates faster, thereby obtaining a greater impact strength through the contact head 33, so that the cleaning effect is better;

[0027] The contact head 33 is provided with a plurality of cleaning whiskers 34.

[0030] Working principle of the utility model: When the utility model is used, the air intake main unit 1 is installed outside the greenhouse, and the ventilation pipe 2 is allowed to enter the greenhouse. Then, the air extractor 13 is started, and the outside air is sucked in through the air extractor 13 and enters through the air intake housing 11. At the same time, under the filtration of the filter 12, the air enters the ventilation pipe 2 and is transported to the greenhouse, so that the temperature and oxygen content in the greenhouse meet the conditions for plant growth. When the air enters, the flowing airflow simultaneously impacts the inner arc of the arc-shaped wind blade 31, thereby causing the arc-shaped wind blade 31 to generate The power of rotation drives the outer rotating circle 22 to rotate. As it rotates, the contact head 33 on the top of the arc-shaped wind blade 31 periodically contacts the surface of the filter 12, and scrapes the attachments on the surface of the filter 12 during contact, while hitting the filter 12 to vibrate it, loosening the attachments.
