Description

Technical Field

[0001] The utility model belongs to the technical field of greenhouse planting, and in particular relates to a ventilation device for a grape planting greenhouse. Background Art

[0002] Greenhouse cultivation of agricultural products is a common agricultural planting method, mainly used for the production of crops such as vegetables, fruits, and flowers. Among them, the ventilation device of greenhouse cultivation has a significant impact on the growth environment of crops. Ventilation equipment can promote gas exchange in the greenhouse and play a role in regulating the humidity and temperature in the greenhouse.

[0003] Typically, ventilation equipment such as negative pressure fans are embedded in the two side walls of a greenhouse or hung at a higher position inside the greenhouse. However, regardless of whether the installation method is embedded or hung, the area to which the airflow blown by a fan can diffuse is limited, and the area of ​​a greenhouse is generally large. If the airflow needs to be diffused to a larger area, the number of fans must be increased, which increases the cost and energy consumption. The increase in fans and motors also easily leads to the risk of electric shock. Therefore, a ventilation device for grape-growing greenhouses is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a ventilation device for a grape growing greenhouse to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a ventilation device for a grape growing greenhouse, comprising:

[0006] Fan;

[0007] A guide assembly includes a fixing frame and a diverter ring. Two fixing frames are provided, and the two fixing frames are symmetrically distributed with the diverter ring as the center. The fan is fixedly installed on one of the fixing frames, and the wind direction of the fan is toward the other fixing frame. A first guide plate is arranged between the fixing frame and the diverter ring, and the first guide plate is inclined at a predetermined angle to the circumferential side of the diverter ring.

[0008] As a preferred solution, the guide assembly further includes a second guide plate, which is spaced apart from the diverter ring and inclined at a predetermined angle to the upper and lower surfaces of the diverter ring.

[0009] As a preferred solution, the fixing frame includes a fixing ring and a fixing rod, and the fixing rod is fixedly installed on the fixing ring.

[0010] As a preferred solution, two fixing rods are provided, and the two fixing rods are perpendicular to each other.

[0011] As a preferred solution, the fixing frame further includes a rotating shaft, and the end of the rotating shaft is fixedly installed in the middle of the two fixing rods.

[0012] As a preferred solution, the axial direction of the rotating shaft is perpendicular to the circumferential surfaces of the diverter ring and the fixed ring.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model is provided with a fixing frame, a first guide plate and a diverter ring. The first guide plate is arranged between the fixing frame and the diverter ring at intervals. The first guide plate is inclined at a predetermined angle to the circumferential side surface of the diverter ring. In this way, when the first guide plate is rotated by the rotating shaft, the wind blown out by the fan is diverted by the first guide plate arranged at intervals, so that the wind flow is spread to a wider area in the greenhouse, thereby improving the ventilation efficiency.

[0015] The utility model is provided with a diverter ring and a second guide plate. During the process of the rotating shaft rotating the diverter ring and the second guide plate, since the second guide plate is arranged at intervals in the diverter ring, the wind direction changes again when the wind flow contacts the second guide plate, thereby diffusing the wind flow to other directions in the greenhouse, further improving the ventilation efficiency in the greenhouse.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] The following examples are intended to illustrate the present invention and are not intended to limit the scope of protection of the present invention. The conditions in the examples may be further adjusted according to specific conditions. Simple improvements to the method of the present invention based on the concept of the present invention fall within the scope of protection claimed by the present invention.

[0023] See also Figure 1-4 The utility model provides a ventilation device for a grape growing greenhouse, comprising:

[0024] Fan 1 is provided to supply air into the greenhouse, thereby accelerating the air flow rate in the greenhouse and improving the ventilation effect in the greenhouse;

[0025] The guide assembly 2 includes a fixing frame 21 and a diverter ring 22. Two fixing frames 21 are provided, and the two fixing frames 21 are symmetrically distributed with the diverter ring 22 as the center, so that the device is more stable. The fan 1 is fixedly installed on one of the fixing frames 21, and the wind direction of the fan 1 is toward the other fixing frame 21, so that the wind direction sent by the fan 1 is from one fixing frame 21 to the other fixing frame 21. A first guide plate 23 is arranged between the fixing frame 21 and the diverter ring 22. The first guide plate 23 is inclined at a predetermined angle to the circumferential side surface of the diverter ring 22. By providing the inclined first guide plate 23, the wind blown by the fan 1 changes its direction after contacting the first guide plate 23, so that the wind flow is diffused to a wider area in the greenhouse, thereby making full use of the wind flow blown by the fan 1 and accelerating the air flow in the greenhouse;

[0026] The guide assembly 2 further includes a second guide plate 24, which is spaced apart from the diverter ring 22. The second guide plate 24 is inclined at a predetermined angle to the upper and lower surfaces of the diverter ring 22. By providing the inclined second guide plate 24, the direction of the wind blown out by the fan 1 is changed in the vertical direction, further diffusing the wind flow, thereby improving the ventilation effect in the greenhouse. In addition, by providing the diverter ring 22, the first guide plate 23 between the fixing frame 21 and the diverter ring 22 remains stable when receiving the wind flow from the fan 1.

[0027] The fixing frame 21 includes a fixing ring 211 and a fixing rod 212. The fixing rod 212 is fixedly mounted on the fixing ring 211. By providing the fixing ring 211 and the fixing rod 212, the overall structure is made more stable during rotation, thereby increasing the service life of the equipment and reducing maintenance costs.

[0028] Two fixing rods 212 are provided, and the two fixing rods 212 are perpendicular to each other. By providing two fixing rods 212, the first deflector 23 will not loosen when receiving the wind flow from the fan 1, further ensuring the stability of the overall structure, preventing it from falling apart due to excessive wind flow, and reducing maintenance costs.

[0029] The fixing frame 21 further includes a rotating shaft 213, the end of which is fixedly installed between the two fixing rods 212. The rotating shaft 213 is provided to rotate the fixing rods 212 and the fixing ring 211 connected to the fixing rods 212, thereby rotating the first guide plate 23 and the second guide plate 24. The fan 1 continuously supplies air into the greenhouse, so that the air flow is continuously diffused to various areas in the greenhouse, thereby improving the ventilation effect in the greenhouse. In addition, since the rotating shaft 213 rotates at a slow speed, the energy consumption of the driving device for driving the rotating shaft 213 is also small, thereby reducing electricity costs.

[0030] The axial direction of the rotating shaft 213 is perpendicular to the circumferential surfaces of the diverter ring 22 and the fixed ring 211. In this way, when the rotating shaft 213 rotates, the diverter ring 22 and the fixed ring 211 can also rotate together around the rotating shaft 213, thereby gradually spreading the wind sent by the fan 1 to a wider area in the greenhouse, thereby improving the wind flow diffusion effect;

[0031] The working principle and use process of this utility model:

[0032] First, the farmer creates mounting holes on the opposite side walls of the greenhouse where the ventilation equipment is to be installed, which are compatible with the fixing ring 211 and the fan 1. Then, the guide assembly 2 is horizontally installed on the side walls of the greenhouse. At this time, the mounting holes on the opposite side walls of the greenhouse form convection, allowing the air sent by the fan 1 to flow better in the greenhouse, ensuring the best ventilation effect in the greenhouse.

[0033] After the installation is completed, the fan 1 is driven by the driving device and starts to supply air. The wind direction of the fan 1 is toward the other opposite fixing frame 21. At this time, the area where the wind delivered by the fan 1 is diffused in the greenhouse is limited; at the same time, the rotating shaft 213 is also driven by the driving device to rotate along its own axis, thereby driving the fixing ring 211 and the first guide plate 23 provided on the fixing ring 211 to rotate around the center of the fixing ring 211. Since the first guide plate 23 is arranged at an angle, during the rotation of the first guide plate 23, the wind blown by the fan 1 is diverted by the first guide plates 23 arranged at intervals, so that the wind flow is diffused to a wider area in the greenhouse, thereby improving the ventilation efficiency;

[0034] In addition, when the rotating shaft 213 rotates the fixed ring 211 and the first guide plate 23, the diverter ring 22 and the second guide plate 24 also rotate together. Since the second guide plate 24 is spaced apart in the diverter ring 22, the wind direction changes again when the wind flows in contact with the second guide plate 24, thereby spreading the wind flow in other directions, further improving the ventilation efficiency in the greenhouse.

[0035] In this way, by arranging multiple fans 1 and guide components 2 in the greenhouse, the wind delivered by the fan 1 can be diffused to the largest area in the greenhouse, thereby making full use of the wind flow delivered by the fan 1, reducing electricity costs and energy consumption while also reducing electrical maintenance costs.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
