Detailed Description

The foregoing and other technical matters, features and effects of the present invention will be described in detail with reference to the accompanying drawings 1 to 12.

Embodiment 1, automatic ventilation device in meat chicken coop, as shown in figure 1, including chicken coop 1, the improvement part of this scheme lies in: the chicken coop comprises a chicken coop 1 and is characterized in that a plurality of air supply devices are respectively arranged on two longitudinal sides of the chicken coop 1 at intervals, as shown in the attached drawing 3, cavities 2 communicated with the air supply devices are respectively arranged on two side walls of the chicken coop 1, as shown in the attached drawing 4, openings 3 are vertically arranged at intervals at one end, far away from the side walls of the chicken coop 1, of each cavity 2, guide plates 4 are rotatably arranged at the positions of the openings 3, inclined plates 5 matched with the openings 3 are integrally arranged on the outer walls of the cavities 2, rectangular holes 6 are formed in the bottoms of the cavities 2, and opening and closing plates 7 are rotatably arranged in the rectangular holes 6;

when the device works, the air supply device continuously conveys airflow from the top of the henhouse 1 to the cavity 2 which is matched with the henhouse, and initially, the guide plates 4 are in the maximum opening state (the guide plates 4 which are positioned on the same cavity 2 are connected with the control transmission device together and are stably kept in the current state under the action of the control transmission device), and the opening and closing plate 7 is in the closing state, as shown in figure 10, at the moment, the temperature in the henhouse 1 is not very high relatively, the airflow generated by the air supply device enters the cavity 2 and blows to the guide plate 4 in the maximum opening state, and then the airflow changes the flowing direction under the action of the guide plates 4 and enters the henhouse 1 through the opening 3 arranged on the side wall of the cavity 2, because the inclined plate 5 (arranged obliquely upwards) matched with the opening 3 is arranged on the side wall of the cavity 2, as shown in fig. 3), therefore, the air flow coming out from the opening 3 is guided by the inclined plate 5 to spread towards the top of the chicken house 1, and because the plurality of guide plates 4 are vertically arranged on the side wall of the cavity 2 at intervals, the air flow generated by the air supply device continuously enters the chicken house 1 through the plurality of openings 3 and blows upwards to the chicken house 1 along the arrangement direction of the inclined plate 5;

note: because the air with higher temperature in the henhouse 1 is positioned above the henhouse 1 (the hot air is lighter) and the air with lower temperature is positioned below the henhouse 1 (the cold air is heavier), the hot air positioned above the henhouse 1 is blown out of the henhouse 1 upwards by the airflow blown out through the opening 3 (as shown in the attached drawing 3, a ventilation hole 8 is arranged in the middle of the top wall of the henhouse 1, the air with higher temperature meshed with the henhouse 1 is blown out of the henhouse 1 under the blowing of high-speed airflow, and the effect of reducing the temperature in the henhouse 1 is achieved;

in the process, because the airflow generated by the air supply device is not directly blown to the surfaces of the chicken flocks, stress reaction can not be generated on the chicken flocks, the temperature can not be reduced, the influence on the chicken flocks can not be caused, if the temperature in the chicken house 1 continuously rises, the temperature sensor detects that the temperature continuously rises, the microcontroller controls the motor to start, the motor starts to drive the control transmission device to act so as to drive the opening angle of the guide plate 4 to be gradually reduced, the opening and closing plate 7 in the closed state is synchronously driven to slowly open outwards along with the action of the control transmission device, as shown in figure 4, each cavity 2 is matched with one control transmission device, and a plurality of control transmission devices positioned on the same side of the chicken house 1 are driven by the same motor (the control transmission devices are connected through belt transmission and are shown in the figure but not numbered), and then when the motor starts, realize through control transmission that it drives its opening angle of 4 slow reductions of guide plate that correspond with it and will locate 2 bottoms of cavity switching board 7 and slowly open, the air current that air supply arrangement produced this moment gets into the volume in the chicken coop 1 through a plurality of openings 3 and reduces gradually, and the air current in cavity 2 begins to spread to 1 of chicken coop through the rectangular hole 6 of locating 2 bottoms of cavity gradually, notes: the airflow is diffused into the henhouse 1 through the rectangular holes 6, so that the airflow is directly blown to the chicken flocks to realize the effects of quickly cooling and radiating the chicken flocks (but a certain stress reaction is generated on the chicken flocks in the case);

if the temperature in the henhouse 1 is continuously raised, the motor is controlled to continue to start under the action of the microcontroller and drives the guide plates 4 to continue to rotate towards the closing direction (the opening and closing plate 7 continues to rotate towards the maximum opening state), so that the guide plates 4 are completely closed (the opening and closing plate 7 is in the maximum opening state), the airflow generated by the air supply device is completely diffused into the henhouse 1 through the rectangular holes 6 and directly blown to the surfaces of the chicken flocks (the effect of quickly cooling and radiating the chicken flocks is realized), the airflow diffused into the henhouse 1 through the rectangular holes 6 finally overflows outwards through the plurality of ventilation holes 8 arranged on the top wall of the henhouse 1, as shown in fig. 3, baffles 26 are installed on the ventilation holes 8 at intervals to prevent other external impurities from entering the chicken coop through the ventilation holes 8 (in rainy days, the baffles also play a role of water proofing);

note: the motor does not work all the time in this scheme, but temperature sensor detects the temperature rise certain degree in the chicken coop 1 (can carry out corresponding settlement according to the geographical position climatic environment of chicken coop department), microcontroller just controls the motor start and stops work once more after controlling it to rotate certain angle (realize that every time motor start-up work can drive a plurality of guide plates 4 and rotate certain angle towards the direction of closing, make shutter 7 rotate certain angle towards the direction of opening, when a plurality of guide plates 4 are in and close and shutter 7 are in the biggest opening state, microcontroller control motor can not continue the operation), microcontroller in this scheme, including a motor, temperature sensor all has external power supply through wire electric connection.

along with the gradual increase of the opening angle of the opening and closing plate 7 (the opening angle of the guide plates 4 is gradually reduced), more and more airflow flows through the bottom of the cavity 2, so that the air flow rate at the bottom of the cavity 2 is further increased, the air pressure at the position of the rectangular hole 6 at the bottom of the cavity 2 is further reduced, at the moment, the sealing plate 9 is in the maximum opening state under the action of air pressure difference, the air flow of outside air entering the cavity 2 through the overflow hole 23 is also maximum, and at the moment, the henhouse 1 is in the maximum cooling and heat dissipation state;
