Description

Technical Field

[0001] This utility model relates to the field of indoor aquaculture technology, specifically a negative pressure ventilation device with wind direction guidance function. Background Art

[0002] Indoor livestock farming refers to the method of raising livestock in areas with livestock sheds or barns. This method can avoid the effects of adverse climatic factors such as wind, rain, scorching sun, and low temperatures, which is conducive to the control of the microclimate environment and facilitates scientific feeding management and mechanized operations.

[0003] During indoor breeding, since the indoor environment is relatively closed, negative pressure ventilation devices are installed to ensure air circulation.

[0004] In existing technologies, negative pressure ventilation devices are installed in fixed locations. Due to the large space inside the shed, there will be dead corners for ventilation. The air circulation in these dead corners is poor, which in turn affects the lives of the livestock.

[0005] In view of this, there is an urgent need for a negative pressure ventilation device with wind direction guidance function. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A negative pressure ventilation device with wind direction guiding function includes: a ventilation frame, a fan disposed within the ventilation frame, and a guiding mechanism, wherein the inner side of the ventilation frame is a ventilation channel;

[0009] The guiding mechanism includes a guiding frame, a guide plate horizontally set within the guiding frame, and an adjustment component for adjusting the angle between the guide plate and the horizontal plane. The guiding frame is located at one end of the ventilation frame near the interior of the building, and the inner side of the guiding frame is a guide channel.

[0010] Its further feature is that,

[0011] One end opening of the air guide channel coincides with the lower half of the ventilation channel opening.

[0012] There are two air guide plates, which are arranged in parallel.

[0013] A partition is provided on the inner side of the guide frame between the two air guide plates, and the partition divides the ventilation channel into an upper channel and a lower channel.

[0014] The air guide plate is provided with a rotating shaft, and the two ends of the rotating shaft are rotatably connected to the guide frame.

[0015] The adjustment component includes a throttle, which is located on the outside of the guide frame and coaxially connected to one end of the rotating shaft.

[0016] A grille is provided at the end of the ventilation frame away from the guide frame.

[0017] The ventilation frame is rectangular.

[0018] The guide frame is rectangular.

[0019] A cross is installed inside the ventilation frame, and the fan is mounted on the cross.

[0020] The above-described structure of this utility model can achieve the following beneficial effects:

[0021] When in use, the fans in the ventilation duct provide negative pressure ventilation. During ventilation, the angle of the air guide plate is adjusted by adjusting the components to guide the direction of air extraction, thereby avoiding the problem of poor air circulation in dead corners inside the building.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0026] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0027] The following is in conjunction with the appendix Figure 1-2This application will be described in further detail.

[0028] refer to Figure 1 and Figure 2 The negative pressure ventilation device with wind direction guidance function shown includes: a ventilation frame 1, a fan 2 installed in the ventilation frame 1, and a guiding mechanism. The inner side of the ventilation frame 1 is a ventilation channel. The guiding mechanism includes a guiding frame 3, a guide plate 4 horizontally installed in the guiding frame 3, and an adjustment component for adjusting the angle between the guide plate 4 and the horizontal plane. The guiding frame 3 is located at the end of the ventilation frame 1 near the inside of the building, and the inner side of the guiding frame 3 is a guiding channel. In use, the fan 2 in the ventilation channel performs negative pressure ventilation. During ventilation, the angle of the guide plate 4 is adjusted by the adjustment component to guide the air extraction direction, thereby avoiding the problem of poor air circulation in dead corners inside the building.

[0029] like Figure 2 As shown, one end of the air guide channel coincides with the lower half of the ventilation channel opening, meaning that the exhaust direction of the upper half of the ventilation channel remains unchanged, ensuring that the wind direction of the upper half of the ventilation channel cross-section remains unchanged. By manually intervening to adjust the angle of the air guide plate 4, the wind direction of the lower half of the ventilation channel cross-section is adjusted to promote airflow in dead corners.

[0030] like Figure 2 As shown, in order to further improve the flexibility of the exhaust air direction, there are two air guide plates 4. The two air guide plates 4 are arranged in parallel and the angle of each air guide plate 4 can be adjusted independently. Furthermore, a partition 5 is provided on the inner side of the guide frame 3 between the two air guide plates 4. The partition 5 divides the ventilation channel into an upper channel and a lower channel, so that the two air guide plates 4 can adjust the exhaust air direction of the upper channel and the lower channel respectively.

[0031] like Figure 2 As shown, the specific installation method of the air guide plate 4 is as follows: the air guide plate 4 is provided with a rotating shaft, and the two ends of the rotating shaft are rotatably connected to the guide frame 3; in order to facilitate the adjustment of the angle of the air guide plate 4, the adjustment component includes a handle 6, the handle 6 is set on the outside of the guide frame 3 and is coaxially connected to one end of the rotating shaft. By rotating the handle 6, the rotating shaft is rotated, thereby rotating the air guide plate 4.

[0032] Further optimizations include, for example Figure 2 As shown, in order to prevent foreign objects from entering the ventilation channel, a grille 7 is provided at the end of the ventilation frame 1 away from the guide frame 3, which plays a protective role while ensuring ventilation.

[0033] Further optimization involves making both the ventilation frame 1 and the guide frame 3 rectangular for ease of installation and production. A cross 8 is installed inside the ventilation frame 1, and the fan 2 is mounted on the cross 8, improving the ease and stability of fan 2 installation.

[0034] The working principle of this utility model is as follows: When in use, the fan 2 in the ventilation channel performs negative pressure ventilation. During ventilation, the angle of the air guide plate 4 is adjusted by adjusting the component to guide the direction of air extraction, thereby avoiding the problem of poor air circulation in dead corners inside the building.

[0035] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
