Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural greenhouse ventilation, and in particular relates to an auxiliary ventilation system for an agricultural greenhouse. Background Art

[0002] Agricultural greenhouses, also known as greenhouses, are a special type of greenhouse that has a plant cultivation system with shelter and heating equipment. Agricultural greenhouses are composed of supporting structures and covering materials, among which transparent plastic films are mostly used as covering materials, which can effectively increase the temperature inside the greenhouse and promote the growth of crops. Agricultural greenhouses use sunlight and artificial heating and ventilation to regulate temperature and humidity, providing a suitable growth environment for crops.

[0003] Different crops have different requirements for temperature when growing. Ventilation can help regulate the temperature in the greenhouse to keep it within the appropriate range required for crop growth. When the indoor temperature does not change or drops, the relative humidity of the air increases significantly. Ventilation can help remove excess water vapor from the indoor air and reduce the relative humidity of the indoor air, thereby preventing the adverse effects of excessive humidity on crop growth. This means that the ventilation equipment of the greenhouse needs to operate non-stop for 24 hours. Such a setting not only wastes energy, but also greatly reduces the service life of the greenhouse. Therefore, whether it is possible to provide an auxiliary ventilation system for agricultural greenhouses that can open the lower part of the greenhouse within a certain period of time, so that natural ventilation replaces artificial ventilation and reduces resource consumption is a technical problem that needs to be solved in this utility model. Summary of the invention

[0004] In view of this, the utility model discloses an auxiliary ventilation system for an agricultural greenhouse. Through the combination of a hydraulic telescopic rod and a roller, a plastic film is driven to be unfolded or retracted on the greenhouse wall, creating a physical gap, so that natural ventilation can replace artificial ventilation, thereby reducing energy waste.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: an auxiliary ventilation system for an agricultural greenhouse, comprising a vent opened at the lower part of the side wall of the greenhouse, a drive component installed at the lower part of the side wall of the greenhouse and located on the inner side of the vent: a cross bar is provided at the lower part of the side wall of the greenhouse, and the cross bar is installed on the inner frame of the greenhouse; the drive component is longitudinally arranged at the lower part of the cross bar, and a fixed plate is installed at the bottom of the drive component; a plurality of the first guide components are longitudinally arranged between the cross bar and the fixed plate; the storage component is rollingly installed on the lower side of the fixed plate, and the plastic film at the vent is connected and wound in the storage component; both sides of the fixed plate are connected to the second guide component; the induction control component is connected to the drive component.

[0006] Furthermore, the driving assembly includes a hydraulic telescopic rod, and the hydraulic telescopic rod is longitudinally installed between the cross bar and the fixed plate.

[0007] Furthermore, the plurality of first guide assemblies include a first column and a second column; the top end of the first column is fixed on the cross bar, the bottom end of the first column is open, and the inner side thereof is a hollow structure; the second column is inserted and placed on the lower side of the first column, and the lower end of the second column is fixedly mounted on the fixed plate.

[0008] Furthermore, the storage assembly includes a roller; auxiliary plates are vertically arranged at both ends of the bottom of the fixed plate, and both ends of the roller are rollingly installed on the auxiliary plates; the bottom edge of the plastic film is fixed on the roller.

[0009] Furthermore, the second guide assembly includes a guide groove, a slider and a connecting rod, the two guide grooves are respectively installed on both sides of the fixed plate, the outer sides of the two auxiliary plates are respectively connected to the slider through the connecting rod, and the slider is installed on the guide groove.

DETAILED DESCRIPTION

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0020] It should be noted that the terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0021] It should be noted that in the present application, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention. Example

[0022] like Figure 1-4 As shown, an auxiliary ventilation system for an agricultural greenhouse includes a vent 1 opened at the lower part of the greenhouse side wall, a drive component installed at the lower part of the greenhouse side wall and located inside the vent 1, a storage component, a first guide component, a second guide component and an induction control component.

[0023] A crossbar 2 is provided at the lower part of the side wall of the greenhouse, and the crossbar 2 is welded and installed on the inner frame 3 of the greenhouse. The drive assembly is longitudinally arranged at the lower part of the crossbar 2, and a fixing plate 4 is installed at the bottom of the drive assembly. The drive assembly includes a hydraulic telescopic rod 5, which is longitudinally installed between the crossbar 2 and the fixing plate 4.

[0024] The four first guide assemblies are longitudinally installed between the cross bar 2 and the fixed plate 4. The four first guide assemblies include a first column 6 and a second column 7. The top of the first column 6 is welded and fixed to the cross bar 2, the bottom end of the first column 6 is open, and the inner side thereof is a hollow structure. The second column 7 is inserted and placed on the lower side of the first column 6, and the lower end of the second column 7 is fixedly installed on the fixed plate 4. When the hydraulic telescopic rod 5 is working, it will drive the fixed plate 4 to move longitudinally, thereby indirectly driving the telescopic movement of the second column 7 on the first column 6. This setting is mainly to ensure that the fixed plate 4 will not deflect to one side during the movement.

[0025] The storage assembly is rollably mounted on the lower side of the fixed plate 4, and the plastic film 9 at the vent 1 is connected and wound inside the storage assembly. Specifically, the storage assembly includes a roller 8. Auxiliary plates are vertically fixed at both ends of the bottom of the fixed plate 4, and both ends of the roller 8 are rollably mounted on the auxiliary plates. The bottom edge of the plastic film 9 is fixed on the roller 8.

[0026] Both sides of the fixed plate 4 are connected to the second guide assembly. The second guide assembly includes a guide groove 10, a slider 11 and a connecting rod 12. The two guide grooves 10 are respectively installed on both sides of the fixed plate 4. The outer sides of the two auxiliary plates are respectively connected to the slider 11 through the connecting rod 12, and the slider 11 is installed on the guide groove 10. When the fixed plate 4 is lifted and lowered under the drive of the hydraulic telescopic rod 5, the slider 11 will be indirectly driven by the connecting rod 12 to move vertically on the guide groove 10. This device is also to ensure that the fixed plate 4 will not deflect to one side during the movement. The guide groove can also be installed in the inner frame of the greenhouse, which is not shown in the attached figure.

[0027] The sensing control component is connected to the driving component. The sensing control component includes a temperature sensor 14 and a humidity sensor 15 connected to the microcontroller 13. The temperature sensor 14 and the humidity sensor 15 are respectively installed on the outer wall of the greenhouse, and one end of the microcontroller 13 is connected to the hydraulic telescopic rod 5. The microcontroller can use an AT8951 controller. The temperature sensor 14 and the humidity sensor 15 are used to monitor the temperature and humidity outside the greenhouse. When the temperature value is between 20°C and 28°C, and the humidity value is between 55%-90, the microcontroller 13 controls the hydraulic telescopic rod 5 to drive the fixed plate 4 to move, thereby driving the plastic film 9 at the vent 1 to be stored on the roller 8 to circulate natural wind.

[0028] Ten adhesive rods 16 are longitudinally installed at the vent 1, and ten adhesive patches 17 are arranged on the plastic film 9 at the vent 1 at positions corresponding to the adhesive rods 16. This arrangement is to ensure that when the plastic film 9 falls and unfolds, it can be firmly adhered to the greenhouse frame 3 to avoid warping and the like. The adhesive rod 16 includes an intermediate rod body and a Velcro attached to the outer periphery of the intermediate rod body, and the hook surface of the Velcro faces the plastic film 9; the adhesive patch 17 can be a Velcro fur surface, and after the plastic film 9 is unfolded, the Velcro fur surface will be attached to the Velcro hook surface, thereby generating a certain adhesive force to prevent the plastic film 9 from warping. Multiple magnetic sheets can be installed in the adhesive patch 17 and the adhesive rod 16 to assist in helping the plastic film to stick to the adhesive rod 16. It should be noted that in this embodiment, the distance between the adhesive rod 16 and the roller does not exceed 5 cm.

[0029] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
