Description

Technical Field

[0001] This utility model relates to the technical field of fan components, specifically to an embedded axial flow fan guide plate for an edible mushroom heat pump unit. Background Technology

[0002] The axial flow fan in a mushroom cultivation heat pump unit is a ventilation device specifically designed for use in such units. Installed inside the heat pump unit, this fan is a key component for achieving airflow and heat exchange. It is primarily used in mushroom cultivation sheds, greenhouses, and similar locations to regulate air temperature and humidity, providing suitable environmental conditions for mushroom growth.

[0003] The existing axial flow fan embedded in the edible mushroom heat pump unit has a guide plate installed at the air outlet of the fan. The guide plate can guide the airflow output by the fan by tilting, so that the output airflow blows in different directions. However, the tilt angle of the existing guide plate cannot be flexibly adjusted according to actual use needs, resulting in significant limitations in use. To address this, we propose an axial flow fan guide plate embedded in the edible mushroom heat pump unit. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an embedded axial flow fan guide plate for edible mushroom heat pump units.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses an embedded axial flow fan guide plate for an edible mushroom heat pump unit, comprising a fan housing, an exhaust port on one side of the fan housing, a plurality of equally spaced guide plates arranged inside the exhaust port, a first spline sleeve fixedly installed on both sides of the guide plate, and a connecting mechanism provided inside the first spline sleeve. The connecting mechanism is installed inside the exhaust port, and the guide plate is installed inside the exhaust port through the connecting mechanism.

[0007] The connecting mechanism includes a second spline sleeve rotatably mounted inside the exhaust port. A drive shaft is inserted into the second spline sleeve, and both ends of the drive shaft are provided with external splines. One end of the drive shaft is splined with the second spline sleeve, and the other end of the drive shaft is inserted into and splined with the first spline sleeve. Annular plates are fixedly mounted on both the second spline sleeve and the drive shaft. An elastic element is sleeved on the drive shaft, and both ends of the elastic element are fixedly connected to the annular plates on both sides. A drive mechanism is mounted on the fan housing, and the drive mechanism is connected to multiple second spline sleeves on one side. The drive mechanism is used to drive multiple guide vanes to rotate.

[0008] As a preferred embodiment of this utility model, the surface of the guide plate is polished and coated with an anti-rust coating.

[0009] As a preferred technical solution of this utility model, the driving mechanism includes a groove formed on the fan housing, one end of each of the second spline sleeves extends into the groove, and the other end of each of the second spline sleeves is fixedly installed with a first bevel gear. A vertical shaft is rotatably installed in the groove, and a plurality of second bevel gears are fixedly installed on the vertical shaft, and the second bevel gears mesh with the first bevel gears respectively.

[0010] As a preferred embodiment of this utility model, a gear is fixedly installed on the vertical shaft, and a protective cover is fixedly installed on the fan housing. The protective cover covers the outside of the tank and is used to seal one side of the tank.

[0011] As a preferred embodiment of this utility model, an electric push rod is fixedly installed inside the protective cover, and a rack is fixedly installed at the output end of the electric push rod, the rack meshing with the gear.

[0012] As a preferred technical solution of this utility model, the electric push rod can lock its current state after it stops working, and maintain a stable position without being disturbed by external forces.

[0013] The beneficial effects of this utility model are:

[0014] This type of edible mushroom heat pump unit features an embedded axial flow fan guide plate. An electric push rod drives a rack to move, which in turn drives a gear to rotate. The gear, vertical shaft, and multiple second bevel gears on the vertical shaft rotate synchronously. These second bevel gears drive the first bevel gear to rotate, causing the second spline sleeve to rotate. The second spline sleeve, drive shaft, and first spline sleeve rotate synchronously, as do the guide plates. This causes multiple guide plates to rotate synchronously and in the same direction, allowing for synchronized adjustment of the tilt angle of the guide plates and thus flexible adjustment of the axial flow fan's airflow direction.

[0015] This application pushes the drive shafts on both sides, causing one end of the drive shaft to disengage from the first spline sleeve and the elastic element to be compressed, thereby separating the first spline sleeves on both sides of the guide plate from the drive shaft on the same side, thus making it easy to remove the guide plate and making subsequent cleaning of the guide plate more convenient.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the present invention relates to an embedded axial flow fan guide plate for a mushroom heat pump unit, comprising a fan housing 1, an exhaust port 2 on one side of the fan housing 1, a plurality of equally spaced guide plates 3 arranged inside the exhaust port 2, a first spline sleeve 4 fixedly installed on both sides of the guide plate 3, and a connecting mechanism provided inside the first spline sleeve 4. The connecting mechanism is installed inside the exhaust port 2, and the guide plate 3 is installed inside the exhaust port 2 through the connecting mechanism. The connecting mechanism includes a second spline sleeve 5 rotatably installed inside the exhaust port 2. A drive shaft 6 is inserted into the second spline sleeve 5. Both ends of the drive shaft 6 are provided with external splines. One end of the drive shaft 6 is splined with the second spline sleeve 5, and the other end of the drive shaft 6 is inserted into the first spline sleeve 4 and splined with the first spline sleeve 4. Annular plates 7 are fixedly installed on both the second spline sleeve 5 and the drive shaft 6. An elastic element 8 is sleeved on the drive shaft 6. Both ends of the elastic element 8 are fixedly connected to the annular plates 7 on both sides. A drive mechanism is installed on the fan housing 1. The drive mechanism is connected to multiple second spline sleeves 5 on one side and is used to drive multiple guide plates 3 to rotate.

[0025] In the prior art, a motor is installed inside the fan casing 1. The motor drives multiple fan blades to rotate and generate airflow, which is directed towards and discharged from the exhaust port 2. Multiple guide plates 3 are set to guide the airflow, and the multiple guide plates 3 are tilted at the same angle, so that the airflow is discharged at a certain angle.

[0026] Among them, the surface of the deflector 3 is polished to reduce the wind resistance generated by the deflector 3, and the surface of the deflector 3 is coated with an anti-rust coating to make the deflector 3 difficult to be modified.

[0027] The drive mechanism includes a groove 9 formed in the fan housing 1. One end of each second spline sleeve 5 extends into the groove 9, and a first bevel gear 10 is fixedly mounted on the other end of each second spline sleeve 5. A vertical shaft 11 is rotatably mounted inside the groove 9, and multiple second bevel gears 12 are fixedly mounted on the vertical shaft 11, each meshing with a first bevel gear 10. A gear 13 is fixedly mounted on the vertical shaft 11. A protective cover 14 is fixedly mounted on the fan housing 1, covering the groove 9 and sealing one side of the groove 9. An electric push rod 15 is fixedly mounted inside the protective cover 14, and a rack 16 is fixedly mounted on the output end of the electric push rod 15, meshing with the gear 13. After the electric push rod 15 stops working, it can lock its current state and maintain a stable position without being disturbed by external forces.

[0028] When the device is working, one end of the drive shaft 6 is inserted into the first spline sleeve 4 and the two are splined together. The electric push rod 15 drives the rack 16 to move, the rack 16 drives the gear 13 to rotate, the gear 13, the vertical shaft 11 and multiple second bevel gears 12 on the vertical shaft 11 rotate synchronously, the second bevel gears 12 drive the first bevel gear 10 to rotate, which can make the second spline sleeve 5 rotate. The second spline sleeve 5, the drive shaft 6 and the first spline sleeve 4 rotate synchronously, the first spline sleeve 4 and the guide plate 3 rotate synchronously, thereby driving multiple guide plates 3 to rotate synchronously and in the same direction, thereby synchronously adjusting the tilt angle of multiple guide plates 3, and thus flexibly adjusting the airflow direction of the axial flow fan.

[0029] When the guide plate 3 needs to be removed and cleaned separately, by pushing the drive shafts 6 on both sides, one end of the drive shaft 6 is disengaged from the first spline sleeve 4 and the elastic element 8 is compressed, so that the first spline sleeves 4 on both sides of the guide plate 3 are separated from the drive shaft 6 on the same side, thus the guide plate 3 can be easily removed, and the subsequent cleaning of the guide plate 3 is also more convenient.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
