Description

Technical Field

[0001] This utility model relates to the field of ventilation fans, and more specifically, to an energy-saving cattle shed ventilation fan. Background Technology

[0002] Ventilation fans utilize the cooling principle of air convection and negative pressure ventilation. They consist of fan blades and a motor. In environments where sunlight shines on buildings, farms, and other heat sources, the temperature in places requiring ventilation is higher than the outdoor temperature. Ventilation fans can quickly expel indoor heat, bringing the indoor temperature to the same level as the outside temperature, preventing the indoor temperature from rising.

[0003] When raising cattle, energy-saving ventilation fans are installed in the farm to reduce the indoor temperature. However, after the existing energy-saving cattle shed ventilation fans are installed, when the wind direction of the external environment of the cattle shed changes, and the height and orientation of the equipment are adjusted to achieve the best effect, the equipment needs to be removed and the height and orientation readjusted before it can be used again. Secondly, the vibration generated when the equipment is running can affect the connection points, which may cause the bolts to fall off.

[0004] Therefore, we made improvements and proposed an energy-saving cattle shed ventilation fan. Utility Model Content

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment proposes an energy-saving cattle shed ventilation fan, including a fan frame 1 and fan blades 2. The fan blades 2 are characterized by a drive motor 3 located directly behind the fan blades 2, with the output end of the drive motor 3 fixedly connected to the axis of the fan blades 2. The fan blades 2 are located inside the fan frame 1, and the drive motor 3 is fixedly connected to the fan frame 1 via a connector. Two symmetrically connected blocks 4 are fixedly connected to one side of the fan frame 1. A connecting rod 5 is movably connected to the bottom end of the uppermost connecting block 4 via a bearing.

A height adjustment mechanism 6 is movably connected to the outer side of the connecting rod 5. An installation mechanism 7 is fixedly connected to the side of the height adjustment mechanism 6 away from the connecting rod 5.

One end of the connecting frame 601... The connecting frame 601 is slidably connected to the outside of the connecting rod 5, and the two connecting blocks 4 are staggered. The bottom end of the connecting rod 5 is movably connected to the top of the connecting seat 605 through a bearing. Two vertically symmetrical fixing plates 8 are fixedly connected to the side of the connecting frame 601 away from the connecting rod 5. The height adjustment mechanism 6 also includes a worm 606, a worm wheel 607 and a control handle 608. The worm 606 and the worm wheel 607 mesh with each other, and the control handle 608 is fixedly connected to one end of the worm 606. The worm wheel 607 is located directly above the connecting seat 605 and is fixedly connected to the outside of the connecting rod 5. Both ends of the worm 606 are movably connected to the outside of the connecting seat 605.

[0033] By aligning the opposite sides of the fixing seat 701 and the clamping block 707 with the edges of the H-shaped steel support column of the cattle shed, and then pushing the fixing seat 701 inward, a tool is inserted into the control hole 10 and turned, thereby causing the control ring 704 to rotate. At this time, the connecting shaft rotates with it, and then the control bar 706 is driven by the thread to move the clamping block 707 outward, clamping the edge of the H-shaped steel support column of the cattle shed onto the opposite sides of the fixing seat 701 and the clamping block 707. The spring 705 moves with the control bar 706, and then the screw is passed through the fixing hole 11 for fixation. This facilitates timely pre-fixation of the equipment and makes it easy to readjust its fixing position. In addition, it reduces the vibration of the equipment during operation to a certain extent and prevents the fixing bolts from falling off due to equipment vibration, thereby improving the installation stability of the equipment.

[0034] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in a preferred embodiment, based on the above method, the mounting mechanism 7 further includes a fixed base 701, a control shaft 702, a support bar 703, a control ring 704, a spring 705, a control bar 706, and clamping blocks 707. The fixed base 701 is U-shaped. The control ring 704 is fixedly connected to the center of the control shaft 702. Two support bars 703 are provided and symmetrically connected to the outside of the control shaft 702 via bearings. The control bar 706 is L-shaped. Clamping blocks 707 are fixedly connected to one end of the control bar 706. Springs 705 are respectively... Located on opposite sides of the control bar 706 and the clamping block 707, several connectors 9 are fixedly connected to the outer side of the control ring 704, and the top of the connector 9 is provided with a control hole 10. The end of the support bar 703 away from the control shaft 702 is fixedly connected to the inside of the fixed seat 701. Fixing holes 11 are provided on both sides of the fixed seat 701 and around the clamping block 707. A set of left-right symmetrical threads are provided on the outer side of the control shaft 702, and the end of the control bar 706 away from the clamping block 707 is movably connected to the outer side of the control shaft 702 through the threads. The spring 705 is sleeved on the outer side of the control shaft 702.

[0035] The worm gear 606 is rotated by manually rotating the control handle 608. At this time, the worm gear 606 drives the turbine to rotate. The connecting rod 5 follows the trajectory of the worm wheel 607 to adjust the angle of the fan frame 1. When the equipment is running and the blowing height needs to be adjusted according to the cattle shed and the weather, the control motor 602 is started to drive the winding roller 603 to rotate, thereby winding and retracting the steel cable 604. Then, the other end of the steel cable 604 is pulled upward to lift the connecting seat 605 and move it along its trajectory. At the same time, the connecting seat 605 pushes the connecting rod 5 upward and slides it on one side of the connecting frame 601. The connecting rod 5 will drive the fan frame 1 to slide upward, thereby adjusting the height of the equipment. This makes it easier to adjust the orientation of the equipment after installation. The height of the equipment can be adjusted at will according to the environment, reducing the difficulty of operation for installers and the adjustment time in the later stage. It ensures the optimal wind direction and angle for heat dissipation and achieves dual energy saving in terms of labor and energy.

[0036] Specifically, during operation / use: Align the opposite sides of the fixing seat 701 and the clamping block 707 with the edges of the H-shaped steel support column of the cattle shed. Then, push the fixing seat 701 inwards. Next, insert a tool into the control hole 10 and turn it, causing the control ring 704 to rotate. The connecting shaft then rotates accordingly, causing the control bar 706 to be driven by the thread, moving the clamping block 707 outwards. This clamps the edge of the H-shaped steel support column of the cattle shed between the fixing seat 701 and the clamping block 707. The spring 705 moves with the control bar 706. Finally, insert the screw through the fixing hole 11 for fixation. After installation, The worm gear 606 is rotated by manually rotating the control handle 608. At this time, the worm gear 606 drives the turbine to rotate. The connecting rod 5 follows the trajectory of the worm wheel 607 to drive the fan frame 1 to adjust the angle. When the equipment is running and the blowing height needs to be adjusted according to the cattle shed and the weather, the control motor 602 is started to drive the winding roller 603 to rotate, so that the steel cable 604 is wound and retracted. Then, the other end of the steel cable 604 is pulled up and the connecting seat 605 moves along its trajectory. At the same time, the connecting seat 605 pushes the connecting rod 5 upward and slides on one side of the connecting frame 601. The connecting rod 5 will drive the fan frame 1 to slide upward, thereby adjusting the height of the equipment.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
