Large-scale chicken farms usually have chicken houses, and raise a large number of chickens in a concentrated manner to improve the output efficiency of products such as chicken and eggs. For chicken houses with a large number of chickens, ventilation and heat dissipation are very important. When the temperature in the chicken house is suitable and the air can circulate effectively, the chickens can grow healthily. In current chicken houses, ventilation and heat dissipation devices are generally set to control the temperature in the chicken house and promote air circulation. The Chinese patent with application number CN202221888372.9 discloses a chicken house with ventilation and heat dissipation functions. The patent opens ventilation windows on the wall panels on the side of the chicken house, and the outer side of each ventilation window is symmetrically provided with an automatically opened and closed window panel assembly, which can enable the window panel body used for ventilation to achieve the effect of automatic opening and closing, thereby realizing the heat dissipation and ventilation of the chicken house. According to Archimedes' principle, the density of hot air is lower than that of cold air. The same volume of hot air is lighter than cold air. Therefore, hot air tends to rise. Although the patent can achieve heat dissipation and ventilation to a certain extent and reduce the temperature of the chicken house, its window panel assembly is opened on the side of the chicken house, with air intake on one side and air exhaust on the other side. The hot air moves in a horizontal direction and the heat dissipation efficiency needs to be further improved. Utility Model Content

DETAILED DESCRIPTION

[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The enumerated embodiments are only used to explain the present invention and are not used to limit the scope of the present invention.

[0019] Embodiment 1

[0020] Reference Figure 1 The present embodiment provides a ventilation and heat dissipation device for a chicken house, including a chicken house body 1, in which a chicken cage 2 is arranged. The chicken house body 1 is also provided with an air inlet mechanism, an air inlet channel 3, an air outlet mechanism, a first temperature sensor 4 and a PLC controller. The air inlet mechanism is used to extract cold air from the outside, and the air inlet mechanism is connected to the air inlet channel 3 and is arranged at the bottom of the chicken house body 1. The air inlet channel 3 is used to guide cold air from the outside to the inside of the chicken house body 1. The air outlet mechanism is arranged at the top of the chicken house body 1, and is used to extract hot air from the inside of the chicken house and discharge it to the outside. The first temperature sensor 4 is used to detect the internal temperature of the chicken house body 1, and the first temperature sensor 4 is connected to the PLC controller signal. A second temperature sensor 5 is arranged outside the chicken house body 1, and the second temperature sensor 5 is used to detect the external environment temperature, and the second temperature sensor 5 is connected to the PLC controller signal. The PLC controller is used to control the air inlet mechanism and the air outlet mechanism.

[0021] Specifically, the air intake mechanism includes a plurality of air intake fans 6, which are arranged in the interlayer at the bottom of the chicken house body 1. An air inlet is arranged below the interlayer at the bottom of the chicken house body. The air inlet end of the air intake fan 6 faces the air inlet. An air supply channel 7 is also arranged in the interlayer. The air outlet end of the air intake fan 6 is connected to one end of the air supply channel 7, and the other end of the air supply channel 7 is connected to the air inlet channel 3. The air intake fan 6 is connected to the PLC controller through a control circuit.

[0022] In this embodiment, the air inlet channel 3 is vertically arranged on the inner side of the chicken house body 1, and an air inlet hole is arranged on the side of the air inlet channel facing the chicken cage 2. The air inlet fan 6 draws cold air from the outside through the air inlet and introduces it into the air supply channel 7. The cold air passes through the air supply channel 7 and the air inlet channel 3 in turn, and finally enters the inside of the chicken house body 1 through the air inlet hole on the side of the air inlet channel 3.

[0023] As an optional example, a support portion 8 is provided at the bottom of the chicken house body 1, and the support portion 8 is used to increase the ground clearance of the chicken house body 1, so that the air intake fan 6 can draw more cold air.

[0024] Specifically, the air outlet mechanism includes a plurality of air outlet fans 9 and an air outlet channel 10. The air outlet fan 9 is arranged in the interlayer at the top of the chicken house body 1. A first air outlet 11 is arranged at the bottom of the interlayer at the top of the chicken house body 1, and a second air outlet 12 is arranged at the top. The first air outlet 11 is connected to the interior of the chicken house body 1. The air inlet end of the air outlet fan 9 faces the first air outlet 11, and the air outlet end thereof is connected to one end of the air outlet channel 10. The other end of the air outlet channel 10 is connected to the second air outlet 12. The air outlet fan 9 is connected to the PLC controller through a control circuit.

[0025] In this embodiment, the air outlet fan 9 draws hot air from above the interior of the chicken house body 1 through the first air outlet 11, and discharges it to the outside through the air outlet channel 10, thereby forming an air duct with air inlet at the bottom and air outlet at the top inside the chicken house body 1, making full use of the upward movement trend of hot air and improving the heat dissipation and ventilation efficiency.

[0026] In addition, the PLC controller can detect the temperature inside and outside the chicken house body 1 through the first temperature sensor 4 and the second temperature sensor 5 respectively. When the internal temperature is high and the external temperature is low, the PLC controller controls the operation of the outlet fan 9 and the inlet fan 6, thereby actively ventilating and dissipating heat; when the overall external temperature is low and the temperature inside the chicken house body 1 needs to be maintained, the inlet fan 6 and the outlet fan 9 are turned off, or the speed of both is lowered to achieve only basic ventilation and avoid excessive heat loss, making the ventilation and heat dissipation of the device more flexible.

[0027] Embodiment 2

[0028] Based on the above embodiments, Figure 2 The difference between this embodiment and the above-mentioned embodiment is that:

[0029] The inner diameter of the air inlet channel 3 gradually narrows from top to bottom, and the top of the inner part is a curved surface, so that the air flow direction and pressure can be changed to further increase the wind speed.

[0030] In addition, except for the entrance and exit, no large-area ventilation structure is set on the side of the chicken house body 1 to avoid disturbing the air duct. At the same time, a transparent part 13 is set on the side of the chicken house body 1 to facilitate viewing the internal situation of the chicken house body 1 from the outside.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
