Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture technology, and in particular to a ventilation and air exchange device for aquaculture farms. Background Technology
[0002] In livestock farms, the processes of animal respiration and excrement decomposition produce large amounts of harmful gases, such as ammonia, hydrogen sulfide, and carbon dioxide. Ventilation is essential to remove these harmful gases from the sheds in a timely manner. However, existing ventilation systems in livestock farms cannot control the airflow based on the humidity level inside the sheds, which is not conducive to removing humid air, resulting in insufficient comfort and low environmental control capabilities. Furthermore, the airflow generated by fans is relatively unidirectional, which can easily lead to uneven distribution of hot or cold air, resulting in temperature imbalance and reduced uniformity.

[0027] 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.
[0028] Reference Figures 1-5 This utility model provides an embodiment of a ventilation and air exchange device for a livestock farm, including a livestock house 1. A drive assembly 5 is connected to the rear end of the livestock house 1, and an adjustment assembly 13 is connected inside the livestock house 1. An exhaust port 2 is opened on one side of the livestock house 1, and an air inlet 3 is opened on the other side of the livestock house 1. Blades 4 are rotatably connected inside both the exhaust port 2 and the air inlet 3. The drive assembly 5 includes a mounting plate 6. One end of the mounting plate 6 is fixedly connected to the rear end of the livestock house 1. A cylinder 7 is fixedly connected to the top of the mounting plate 6. A connecting block 8 is fixedly connected to the output end of the cylinder 7 through the mounting plate 6. A connecting plate 9 is fixedly connected to the side of the connecting block 8. A rack 10 is fixedly connected to one end of the connecting plate 9. A gear 11 is meshed with one side of the rack 10. A connecting rod 12 is fixedly connected to one end of the gear 11. One end of the connecting rod 12 passes through the inner wall of the livestock house 1 and is fixedly connected to one end of the blade 4.
[0029] The adjustment component 13 includes a motor 14, which is fixedly connected to the outside of the breeding house 1. The output shaft of the motor 14 passes through the breeding house 1 and is fixedly connected to a lead screw 15. One end of the lead screw 15 rotates on the inner wall of the breeding house 1. A fixing block 16 is threaded to the outside of the lead screw 15. A ventilation component 18 is connected to the bottom of the fixing block 16. The ventilation component 18 includes a motor 19. A fan 20 is fixedly connected to the output shaft of the motor 19. A fixing rod 17 is fixedly connected to the inner wall of the breeding house 1. The fixing rod 17 slides inside the fixing block 16 to ensure the stability of the fixing block 16 during movement. A humidity sensor is installed on the inner wall of the breeding house 1 to improve the comfort of the animals. A controller is installed on the outer wall of the breeding house 1. The humidity sensor, controller, cylinder 7, motor 14 and motor 19 are all electrically connected. A door 21 is hinged to the front of the breeding house 1. There are two sets of doors 21 to facilitate the entry and exit of the breeding personnel.
[0030] Working principle: When the humidity inside the breeding house 1 is too high or too low, the humidity sensor detects the change in humidity inside the breeding house 1 and converts it into an electrical signal, which is transmitted to the controller. The controller starts the cylinder 7, which drives the connecting block 8 to move. The connecting block 8 drives the rack 10 to move through the connecting plate 9. The rack 10 drives the gear 11 to rotate. The gear 11 drives the blade 4 to rotate through the connecting rod 12, which can balance the humidity inside the breeding house 1. Then, the motor 14 is started, which drives the lead screw 15 to rotate. The rotation of the lead screw 15 drives the fixed block 16 to reciprocate. While the fixed block 16 reciprocates outside the fixed rod 17, it drives the motor 19 and the fan 20 to reciprocate, making the temperature distribution inside the breeding house 1 more even and improving comfort.
