Description

Technical Field

[0001] This utility model belongs to the field of aquaculture technology, specifically relating to a ventilation and shading device for aquaculture sheds. Background Technology

[0002] Large-scale poultry farming utilizes well-sealed housing environments, which allows bacteria and organic matter to ferment, leading to significant air pollution and foul odors. This not only affects the surrounding environment but also negatively impacts poultry growth. Furthermore, during periods of long hours of sunlight in poultry farming, it's necessary to create a dark environment by confining the poultry in the housing to improve their health and productivity.

[0003] The current treatment method generally involves adding a light-shielding plate to the surface of the fan after ventilation. Although this achieves the effect of blocking natural sunlight, the ventilation efficiency of the fan is greatly reduced in actual use. Moreover, when it is not necessary to create a dark environment, the light-shielding plate cannot be opened or removed, resulting in poor ventilation in the poultry house, which affects the normal growth of poultry. In addition, long-term use will cause a large amount of dust to accumulate on the surface of the light-shielding plate, which requires frequent cleaning. Utility Model Content

The first supporting rotating component is disposed on one side of the inner frame of the fixed frame, and the second supporting rotating component is disposed on one side of the mounting frame. The first supporting rotating component and the second supporting rotating component are symmetrically arranged, and a plurality of steel balls slide between the first supporting rotating component and the second supporting rotating component.

[0022] In order to make the technical problem, technical scheme and advantages of the utility model clearer, the following will be described in detail in combination with the drawings and specific embodiments.

[0023] AsFigures 1-3 As shown, an embodiment of this utility model provides a ventilation and shading device for a livestock shed, including a fixed frame 1. An installation frame 2 is disposed inside the fixed frame 1, and rotating components 3 are provided at the top and bottom of the fixed frame 1. The fixed frame 1 has a hollow, U-shaped structure. Limiting baffles 11 are correspondingly provided on the upper and lower sides of the inner frame of the fixed frame 1. In this embodiment, a fan 5 is also disposed behind the ventilation and shading device. The limiting baffles 11 are positioned perpendicular to the air inlet of the fan 5. During the livestock breeding process, the fan 5 is always in operation. When shading is required, rotating the installation frame 2 will cover the inner frame of the fixed frame 1. Since the axial direction of the air inlet of the fan 5 is perpendicular to the limiting baffles 11, the rotation of the installation frame 2 is restricted, preventing the installation frame 2 from swaying or shaking freely.

[0024] like Figure 4 , 5 As shown, the rotating component 3 is rotatably connected to the mounting frame 2. The rotating component includes a first supporting rotating member 31, steel balls 32, and a second supporting rotating member 33. The first supporting rotating member 31 is disposed on one side of the inner frame of the fixed frame 1, and the second supporting rotating member 33 is disposed on one side of the mounting frame 2. The first supporting rotating member 31 and the second supporting rotating member 33 are symmetrically arranged, and multiple steel balls 32 slide between the first supporting rotating member 31 and the second supporting rotating member 33. Specifically, both the first supporting rotating member 31 and the second supporting rotating member 33 have grooves 34, forming a space for the steel balls 32 to slide. The first and second rotating supporting members are hollow cylindrical structures. Since the first supporting rotating member 31 is fixed to the inner frame of the fixed frame 1, and the second rotating supporting member 33 is fixed to the mounting frame 2, rotating the second rotating supporting member 33 causes the steel balls 32 to move along the grooves 34. That is, the mounting frame 2 rotates around the center of the first supporting rotating member 31, thereby achieving the purpose of shading or ventilation.

[0025] The working principle of this utility model is as follows:

[0026] like Figure 6 As shown, the ventilation and light-shading device is installed on the light-receiving side of the breeding shed, and a fan is installed on the outside of the device. During use, when light is needed in the breeding shed, the steel ball 32 between the first and second supporting rotating parts 31 and 33 can be rotated, causing the mounting frame 2 to rotate within the fixed frame 1 along with the rotating component 3, rotating the mounting frame 2 to 90°. This facilitates ventilation and light transmission in the breeding shed. When a dark environment is needed, the mounting frame 2 is rotated back to its original position. Since the mounting frame 2 contains a light-shading sheet 4, when the mounting frame 2 completely covers the inner frame of the fixed frame 1, the light-receiving surface of the breeding shed is completely closed, achieving a rapid light-shading effect. This design allows the light-shading sheet to be rotated open, reducing usage frequency, dust accumulation, and the frequency of cleaning.

[0027] The above is the preferred embodiment of the present application, it should be noted that, for those skilled in the technical field, without departing from the principles described in the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the scope of protection of the present application.
