Description

Technical Field

[0001] The utility model belongs to the technical field of control systems, and in particular relates to a breeding fan conversion device. Background Art

[0002] With the rise of large-scale and intensive farming and the development of intelligent farming equipment, the ventilation in the whole poultry house is controlled by fans and other equipment. The use of fans is one of the important means of environmental control, so the site is more dependent on the power supply. Power outages or failures may have a serious impact on the farming environment and even cause huge economic losses.

[0003] In the poultry farming process, the fan is usually located at the end of the poultry house, and is powered by the auxiliary control box nearby, and controlled by the main control box and environmental controller at the head of the poultry house. Once a power outage occurs, if the generator connected to the auxiliary control box cannot meet the power supply of the electrical equipment in the entire house, it is necessary to give priority to emergency start of some fans to reduce the heat stress reaction or even death of the flock caused by the temperature rise in the house. Therefore, it is necessary to manually change the wiring of the auxiliary control box involving the fan control part to complete the pull-in of the relay so that the fan can be started in an emergency with the support of the generator.

[0004] However, this requires an experienced electrician to operate, and changing the wiring takes a lot of time, so there is an urgent need for a multi-functional conversion device for aquaculture fans. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a breeding fan conversion device for solving the problem of inconvenient fan startup control during power outages.

The main control circuit breaker supplies power to the load through the contactor. When power is off, there is no need to make additional changes to the wiring. After switching through the control panel module, the start-up of the load fan can continue to be controlled to ensure air circulation and environmental control in the poultry house, helping farms to cope with normal power supply, temporary maintenance and sudden power outages, maintain a good poultry house environment, and ensure the health and growth of poultry.

[0014] Furthermore, the control panel module includes a manual switching module, an emergency wiring terminal and an automatic wiring terminal connected to the input end of the manual switching module, and a signal output terminal connected to the output end of the manual switching module.
