Technical Field
[0001] The utility model relates to the field of breeding, in particular to a closed layer chicken pen small window ventilation negative pressure adjustment system based on transverse temperature difference. Background Art
[0002] Chicken houses can be divided into open chicken houses, semi-open chicken houses and closed chicken houses. Now large-scale farms are basically closed chicken houses. Closed chicken houses can accurately control the ventilation, lighting and other environmental conditions of the chicken houses, which is conducive to improving the production efficiency of chickens. Closed chicken houses are divided into two modes: positive pressure ventilation and negative pressure ventilation. Negative pressure ventilation chicken houses use negative pressure fans to exhaust the air in the chicken house, so that the pressure in the chicken house is less than the outside air pressure, thereby forming a negative pressure. The outside air enters the chicken house through the air inlet of the chicken house, thus forming air flow in the chicken house. Negative pressure ventilation can form a large wind speed, produce a wind cooling effect, and discharge pollutants such as dust and feathers in the chicken house. Therefore, it is currently the most widely used ventilation mode. In the hot and humid summer season, chicken houses use longitudinal ventilation. In order to cool down, the negative pressure and wind speed are generally increased to reduce the body temperature.
[0003] According to patent application number CN202222212345.6, a negative pressure ventilation chicken house with positive pressure micro-control can be known, including a chicken house body, a negative pressure fan is installed on the gable of the chicken house body, an air inlet is arranged on the side wall of the chicken house body, a blower is installed on the side wall of the chicken house body, and an air distribution pipe is installed in the chicken house body, the port of the air distribution pipe is arranged directly opposite the blower, and a plurality of air outlets are arranged on the air distribution pipe. The utility model realizes positive pressure regulation of the air pressure in the chicken house body, controls the air flow more accurately and quickly, and optimizes the chicken house environment. In the process of realizing the utility model, the inventor finds that at least the following problems in the prior art have not been solved, although the outside air is drawn into the chicken house body by the blower and discharged from each air outlet of the air distribution pipe, so that the incoming air can be evenly distributed in the chicken house body. Positive pressure regulation of the air pressure in the chicken house body is realized, so as to control the air flow more accurately and quickly, avoid large temperature differences in various areas in the chicken house, realize effective oxygen supply and temperature control, and optimize the chicken house environment. Meeting the ventilation needs under specific chicken houses, specific climates, and specific needs solves the breathing difficulties of chickens. In severe cases, it causes hypoxia and the mortality rate will increase. In order to increase the negative pressure, the sealing requirements of the chicken house must be high, which increases the construction cost of the chicken house. High negative pressure will seriously affect the efficiency of the fan. The higher the negative pressure, the smaller the air volume, and the power consumption of the fan will increase, causing a waste of resources. However, during use, the traditional closed-type laying hen house small window ventilation negative pressure adjustment system based on lateral temperature difference only allows the incoming air to be evenly distributed in the chicken house itself, and realizes positive pressure regulation of the air pressure in the chicken house itself. This regulation method relies entirely on air distribution, and when the wind force changes, the internal air distribution will also change, resulting in an unstable regulation effect. For this reason, a new technical solution needs to be designed to solve it. Utility Model Content
[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a closed layer chicken house small window ventilation negative pressure adjustment system based on lateral temperature difference, so as to solve the current traditional closed layer chicken house small window ventilation negative pressure adjustment system based on lateral temperature difference, which only makes the incoming air evenly distributed in the chicken house body to achieve positive pressure regulation of the air pressure in the chicken house body. This regulation method relies entirely on air distribution, and when the wind force changes, the internal air distribution will also change, resulting in a technical problem that the regulation effect is not very stable.
[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a closed laying hen house small window ventilation negative pressure adjustment system based on the horizontal temperature difference, including a house main body, and also including:
[0006] A plurality of ventilation windows are respectively provided on the top of both sides of the main body of the enclosure, and a blower is installed at one end of the ventilation window;
[0007] A negative pressure adjustment mechanism is provided between the plurality of ventilation windows, the negative pressure adjustment mechanism comprises a plurality of connection holes, the plurality of connection holes are respectively provided between the plurality of ventilation windows, movable plates are placed at both upper and lower ends of the plurality of ventilation windows, and connecting rods are fixed between the movable plates in the plurality of ventilation windows,
[0008] The connecting hole in the middle is provided with grooves at both the upper and lower ends, an electric telescopic cylinder is installed at one end inside the groove, and a connecting rod is fixed to the other end of the electric telescopic cylinder through the connecting hole.
[0009] Preferably, a circular groove is provided at the front end of the movable plate, and a wind speed sensor is installed inside the circular groove.
[0010] Preferably, one end of the ventilation window located in the main body of the enclosure is connected to a pipe joint, and one end of the pipe joint away from the ventilation window is connected to an arc-shaped pipe.
[0011] Preferably, one end of the arc-shaped pipe away from the pipe joint is a sealed structure.
[0012] Preferably, the bottom of the arc-shaped pipe is connected to a plurality of connecting pipes, and the outer walls of the plurality of connecting pipes are each provided with a plurality of air outlet holes.
[0013] Preferably, a plurality of negative pressure fans are installed at both the front and rear ends of the housing body.
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] 1. The utility model combines ventilation windows, movable plates and electric telescopic cylinders. Two electric telescopic cylinders can be used to drive the movable plates in multiple ventilation windows to move, so as to control the air intake into the ventilation windows. Since the negative pressure value is a method of measuring the wind speed of the small windows, the greater the pressure difference between indoors and outdoors, the greater the wind speed entering the chicken house, and vice versa. Therefore, the application can control the negative pressure value in the pen by adjusting the air intake into the ventilation windows, thereby realizing the adjustment of the negative pressure value. Moreover, since a wind speed sensor is provided on the surface of the movable plate, The device can use the wind speed sensor to detect the wind speed at the ventilation window. According to the wind speed data, the staff can calculate the negative pressure value in real time, which improves the accuracy of the adjustment and solves the problem of the traditional closed layer chicken house small window ventilation negative pressure adjustment system based on lateral temperature difference. It only makes the incoming air evenly distributed in the chicken house, and realizes positive pressure regulation of the air pressure in the chicken house. This regulation method relies entirely on air distribution. When the wind force changes, the internal air distribution will also change, resulting in a technical problem that the regulation effect is not very stable.
[0016] 2. The utility model, through the combination of the arc tube, the connecting tube and the air outlet, can allow the air entering from the ventilation window to enter the connecting tube through the arc tube, and achieve uniform air distribution through the multiple air outlet holes on the surface of the connecting tube, so that the air can be directly distributed to the bottom of the enclosure, and the air flow can be further controlled, thus solving the technical problem that the uniformly distributed air will be dispersed when the air flows to the bottom of the enclosure in the traditional technical solution that directly uses the top pipe to distribute the air.

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments:
[0022] Example 1: A closed layer hen house small window ventilation negative pressure adjustment system based on lateral temperature difference, see Figures 1 to 3, including a housing body 1, and also including: a plurality of ventilation windows 2, which are respectively opened on the top of both sides of the housing body 1, and a blower is installed at one end of the ventilation window 2; a negative pressure adjustment mechanism is opened between the plurality of ventilation windows 2, and the negative pressure adjustment mechanism includes a plurality of connecting holes 202, and the plurality of connecting holes 202 are respectively opened between the plurality of ventilation windows 2, and movable plates 201 are placed at both upper and lower ends of the plurality of ventilation windows 2, and connecting rods 203 are fixed between the movable plates 201 in the plurality of ventilation windows 2, and grooves 206 are opened at both upper and lower ends of the connecting hole 202 located in the middle, and an electric telescopic cylinder 207 is installed at one end of the groove 206, and the other end of the electric telescopic cylinder 207 passes through the connecting hole 202 and is fixed with a connecting rod 203, and the two electric telescopic cylinders 207 can be used to drive the movable plates 201 in the plurality of ventilation windows 2 to move, thereby controlling the air intake into the ventilation windows 2. The pressure value is a method of measuring the wind speed of the small window. The greater the pressure difference between indoors and outdoors, the greater the wind speed entering the chicken house, and vice versa. Therefore, the present application can control the negative pressure value in the pen by adjusting the air intake in the ventilation window 2, thereby achieving the adjustment of the negative pressure value. Moreover, since a wind speed sensor 205 is provided on the surface of the movable plate 201, the wind speed sensor 205 can be used to detect the wind speed at the position of the ventilation window 2. The staff can calculate the negative pressure value in real time based on the wind speed data, thereby improving the accuracy of the adjustment and solving the problem of the traditional closed egg-laying chicken pen small window ventilation negative pressure adjustment system based on lateral temperature difference. It only makes the incoming air evenly distributed in the chicken house body to achieve positive pressure regulation of the air pressure in the chicken house body. This regulation method relies entirely on air distribution, and when the wind force changes, the internal air distribution will also change, resulting in a technical problem that the regulation effect is not very stable.
[0023] For details, see Figure 1 A circular groove 204 is formed at the front end of the movable plate 201 , and a wind speed sensor 205 is installed inside the circular groove 204 .
[0024] For further information, see Figure 3 One end of the ventilation window 2 located in the main body 1 of the enclosure is connected to a pipe joint 3, and one end of the pipe joint 3 away from the ventilation window 2 is connected to an arc-shaped pipe 301.
[0025] It is worth noting that see Figure 3 The end of the arc-shaped pipe 301 away from the pipe joint 3 is a sealed structure.
[0026] It is worth noting that see Figure 3A plurality of connecting pipes 302 are connected to the bottom of the arc-shaped pipe 301, and a plurality of air outlet holes 303 are provided on the outer walls of the plurality of connecting pipes 302. The air entering from the ventilation window 2 will pass through the arc-shaped pipe and enter the connecting pipe 302. The plurality of air outlet holes 303 on the surface of the connecting pipe 302 are used to evenly distribute the air, and the air can be evenly distributed directly to the bottom of the enclosure, and the air flow can be further controlled, which solves the technical problem that the evenly distributed air will be dispersed when the air flows to the bottom of the enclosure in the traditional technical solution that the top pipe is directly used to evenly distribute the air.
[0027] It is worth mentioning that see Figure 1 A plurality of negative pressure fans 101 are installed at both the front and rear ends of the main body 1 of the enclosure.
[0028] When using the closed laying hen house small window ventilation negative pressure adjustment system based on lateral temperature difference, two electric telescopic cylinders 207 can be used to drive the movable plates 201 in multiple ventilation windows 2 to move respectively, so as to control the air intake into the ventilation windows 2. Since the negative pressure value is a method of measuring the wind speed of the small windows, the greater the pressure difference between indoors and outdoors, the greater the wind speed entering the chicken house, and vice versa. Therefore, the present application can control the negative pressure value in the house by adjusting the air intake into the ventilation windows 2, thereby achieving the negative pressure value. Moreover, since a wind speed sensor 205 is provided on the surface of the movable plate 201, the wind speed sensor 205 can be used to detect the wind speed at the position of the ventilation window 2. The staff can calculate the negative pressure value in real time based on the wind speed data, thereby improving the accuracy of the adjustment. The air entering from the ventilation window 2 will pass through the arc tube and enter the connecting pipe 302. The multiple air outlets 303 on the surface of the connecting pipe 302 are used to achieve uniform air distribution, which can directly distribute the air to the bottom of the enclosure, and can further control the air flow.
