Abstract

The invention relates to the field of environmental monitoring equipment, and discloses an air monitoring and early warning device in a pig house. The air monitoring and early warning device comprisesa machine frame, a ventilating pipe is fixed on the machine frame, a wind wheel is rotationally connected in the ventilating pipe, and is coaxially connected with a fan gear, the fan gear is engagedwith a rack, a first wedge rod is slidingly connected in the ventilating pipe, a pump is fixed on the machine frame, the first wedge rod is slidingly connected in the pump, an alarming pipe is arranged on the machine frame, a second wedge rod is slidingly connected on one side of the alarming pipe, an alarming whistle is installed on the second wedge rod, a draught fan is installed on the alarmingpipe, a starting mechanism is installed on the other side of the alarming pipe, a sliding block is slidingly connected in the alarming pipe, is used for closing the starting mechanism, and is also used for abutting against the second wedge rod, and an air outlet is formed in the alarming pipe. Compared with the prior art, through flowing of air in the pig house in the technical scheme, the alarming whistle rings or does not ring through different modes, monitoring of the ventilating condition in the pig house is formed accordingly, and it can be avoided that air in the pig house is muddy.

Description

technical field [0001] The invention belongs to the field of environmental monitoring equipment, in particular to an air monitoring and early warning device in pig houses. Background technique [0002] With the development of factory pig farming, the pig houses for raising pigs are constantly improving. In order to improve the comfort of pigs, many of the existing pig houses are ventilated pig houses with ventilation function. An exhaust fan is installed, and an air supply fan is also installed in the pig house. Generally, some exhaust fans are turned on, and the air is exhausted through the air outlet. , and then turn on the air supply fan to replenish air to ensure that the pig house is kept in a ventilated state. However, there is no device that can detect air quality and ventilation effect in the existing ventilated pig house. However, it is difficult to ensure that the pig house is in a proper ventilation state, and if the ventilation is not smooth, there are often pr...

In order to improve the comfort of pigs, many of the existing pig houses are ventilated pig houses with ventilation function. An exhaust fan is installed, and an air supply fan is also installed in the pig house. Generally, some exhaust fans are turned on, and the air is exhausted through the air outlet. , and then turn on the air supply fan to replenish air to ensure that the pig house is kept in a ventilated state. However, there is no device that can detect air quality and ventilation effect in the existing ventilated pig house. However, it is difficult to ensure that the pig house is in a proper ventilation state, and if the ventilation is not smooth, there are often problems caused by the dirty air and harmful and toxic gases in the pig house being difficult to discharge in time.
