Abstract
Description
Technical Field
[0001] This utility model relates to the field of ventilation equipment technology, specifically to a retractable and reinforced ventilation device. Background Technology
[0002] The main function of ventilation equipment in livestock farms is to regulate the environment inside the sheds, ensure animal health, and improve breeding efficiency. Animals are densely packed inside the sheds, easily generating a large amount of body heat and exhaled carbon dioxide, leading to increased indoor temperature. Ventilation equipment, through powerful exhaust, effectively removes hot air and harmful gases from the sheds, lowering the temperature and improving animal comfort, thus contributing to their healthy growth.
[0003] However, most farm ventilation equipment is installed directly to the wall with bolts, resulting in a small contact area after installation. This makes the bolts prone to loosening after shaking, which in turn causes the ventilation equipment to fall off, resulting in poor reinforcement after installation. Utility Model Content
[0004] The purpose of this invention is to provide a retractable and reinforced ventilation device to solve the problem mentioned in the background art that ventilation devices are not easy to retract and reinforce.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an extendable and reinforced ventilation device, comprising a fixed frame, a mounting bracket, a first locking bolt, a fixed seat, a displacement seat, and a second locking bolt. Mounting brackets are provided at both ends of the fixed frame. The first locking bolt connects the mounting bracket to the mounting wall. Symmetrically distributed fixed seats are provided on one side of the mounting bracket. A displacement seat is provided at one end of each fixed seat. A second locking bolt is provided at the end of the displacement seat away from the fixed seat. A protective frame is provided at the end of the displacement seat closest to the second locking bolt.
[0006] Preferably, the protective frame has a sliding connection to a tie rod inside, and one end of the tie rod is provided with a welded limiting rod.
[0007] Preferably, a limiting spring is connected between one end of the limiting rod and the protective frame.
[0008] Preferably, the displacement seat has a guide rod inside that is welded to the fixed seat, and the guide rod has a matching locking groove on the side near the limiting rod, and the locking groove is symmetrically distributed on one side of the guide rod.
[0009] Preferably, a filter screen is provided inside the fixed frame, and a vertical plate is provided inside the fixed frame near the filter screen. A dual-axis motor is installed on one side of the vertical plate.
[0010] Preferably, each of the output ends of the dual-axis motor is provided with a rotating rod, and a staggered cleaning brush is provided on one side of the rotating rod, with the cleaning brush being staggered on both sides of the filter screen.
[0011] Preferably, one side of the other rotating rod is provided with symmetrically distributed rotating blades.
[0012] Compared with existing technologies, the beneficial effects of the extendable and reinforced ventilation equipment of this utility model are as follows: By pulling the pull rod, the limiting rod can be separated from the locking groove, allowing the displacement seat to extend. Then, the second locking bolt at one end can be rotated, allowing it to be reinforced and connected to the wall after extension. By starting the dual-axis motor, the rotating rod can clean the filter screen using the cleaning brush, thereby accelerating air circulation. This results in better cleaning and air intake effects when the ventilation equipment is used inside a farm. Specifically:
[0013] 1. When ventilation equipment is used in a farm, it is often difficult to extend and reinforce it, making it prone to falling after installation. By pulling the tie rod, the tie rod can move the connected limiting rod. When the limiting rod moves, it can restrict the connected limiting spring, causing the limiting spring to contract. At the same time, when the limiting rod moves, it can separate from the locking groove inside the guide rod, so that the displacement seat can be unrestricted. The displacement seat can then be pulled, allowing it to extend at one end of the fixed seat. Then, the second locking bolt at one end can be rotated, allowing the second locking bolt to be reinforced and connected to the wall after extension. This provides a better extension and reinforcement effect for the ventilation equipment when used in a farm.
[0014] 2. When ventilation equipment is in use, dust and impurities often accumulate on the filter screen after prolonged use. Starting the dual-axis motor allows it to rotate the rotating rods at both ends. These rotating rods then rotate the cleaning brushes connected to one end of the filter screen. Because the cleaning brushes are staggered on both sides of the filter screen, the rotating rods effectively clean the surface of the filter screen, preventing dust from adhering. Simultaneously, the rotating rod at the other end rotates the blades. Since the blades are symmetrically distributed on the surface of the rotating rod, this accelerates airflow, resulting in better cleaning and air intake effects when the ventilation equipment is used in the farm.

[0020] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-4 This utility model provides an extendable and reinforced ventilation device, including a fixed frame 1, a mounting bracket 2, a first locking bolt 3, a fixed seat 4, a displacement seat 5, and a second locking bolt 6. The fixed frame 1 has mounting brackets 2 at both ends. The mounting brackets 2 are connected to the mounting wall by the first locking bolt 3. The mounting brackets 2 have symmetrically distributed fixed seats 4 on one side. The fixed seat 4 has a displacement seat 5 at one end. The displacement seat 5 has a second locking bolt 6 at the end away from the fixed seat 4. The displacement seat 5 has a protective frame 7 at the end near the second locking bolt 6. A pull rod 8 is slidably connected inside the protective frame 7. A limiting rod 9 is welded to one end of the pull rod 8. A limiting spring 10 is connected between the limiting rod 9 and the protective frame 7. The displacement seat 5 has a guide rod 11 welded to the fixed seat 4 inside. The guide rod 11 has a matching locking groove 12 on the side near the limiting rod 9, and the locking grooves 12 are symmetrically distributed on one side of the guide rod 11.
[0022] See Figures 1-4It is known that when ventilation equipment is used in a farm, it is usually not easy to extend and reinforce it, which makes it easy for the ventilation equipment to fall off after installation. By pulling the pull rod 8, the pull rod 8 can move the connected limiting rod 9, so that the limiting rod 9 can restrict the connected limiting spring 10 when it moves, causing the limiting spring 10 to contract. At the same time, when the limiting rod 9 moves, it can separate from the locking groove 12 opened inside the guide rod 11, so that the displacement seat 5 can be unrestricted, and the displacement seat 5 can be pulled, so that the displacement seat 5 can extend at one end of the fixed seat 4. Then, the second locking bolt 6 set at one end can be rotated, so that the second locking bolt 6 can be reinforced and connected to the wall after extension, so that the ventilation equipment can have a better extension and reinforcement effect when used in a farm.
[0023] The fixed frame 1 is equipped with a filter screen 13 inside. A vertical plate 14 is provided on the side of the fixed frame 1 near the filter screen 13. A dual-axis motor 15 is installed on one side of the vertical plate 14. A rotating rod 16 is provided at the output end of each dual-axis motor 15. A cleaning brush 17 is provided on one side of the rotating rod 16. The cleaning brush 17 is staggered on both sides of the filter screen 13. A symmetrically distributed rotating blade 18 is provided on the other side of the rotating rod 16.
[0024] See Figure 1 , Figure 2 and Figure 3 It is known that when ventilation equipment is in use, dust and impurities often accumulate on the filter screen surface after prolonged use. By starting the dual-axis motor 15, the dual-axis motor 15 can rotate the rotating rods 16 connected at both ends. When the rotating rods 16 rotate, they can rotate the cleaning brush 17 connected at one end. Since the cleaning brushes 17 are staggered on both sides of the filter screen 13, the surface of the filter screen 13 can be cleaned after the rotating rods 16 rotate, thus preventing dust from adhering to the surface of the filter screen 13. At the same time, the rotating rods 16 at the other end can rotate the rotating blades 18. Since the rotating blades 18 are symmetrically distributed on the surface of the rotating rods 16, they can accelerate the air circulation, so that the ventilation equipment can have a better cleaning and air intake effect when used in the farm.
[0025] In summary, the main function of ventilation equipment in a farm is to regulate the environment inside the shed, ensure animal health, and improve breeding efficiency. By pulling the lever 8, the limiting lever 9 can be separated from the locking groove 12, allowing the displacement seat 5 to extend. Then, the second locking bolt 6 at one end can be rotated, so that the second locking bolt 6 can be reinforced and connected to the wall after extension.
