Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
1-3 are schematic diagrams of a ventilation device for a farm, which is provided by the embodiment of the utility model, and can be applied to ventilation of livestock and poultry farms such as a pig house and a chicken farm. The ventilation device for the farm in this embodiment includes a ventilation pipe 11 and a diaphragm 12, wherein the ventilation pipe 11 is in a strip shape, and can be fixed above a livestock and poultry cultivation area of the farm, and can realize air flow transportation, for example, can transport outdoor fresh air to the above of the livestock and poultry cultivation area.
The ventilation pipe 11 has a first air inlet 111, a second air inlet 112, a plurality of first air outlets 113 and a plurality of second air outlets 114, wherein the plurality of first air outlets 113 are respectively located at different positions in the axial direction of the ventilation pipe 11, the plurality of second air outlets 114 are respectively located at different positions in the axial direction of the ventilation pipe 11, and the directions of the first air outlets 113 and the second air outlets 114 are different. In particular, when the ventilation pipe 11 is installed in the farm, the positions of the plurality of first air outlets 113 and the plurality of second air outlets 114 may respectively correspond to the positions of different cultivation areas in the farm, for example, when the ventilation pipe 11 is installed in a pig shed, the plurality of first air outlets 113 and the plurality of second air outlets 114 may respectively be located above the plurality of different pig houses.
The diaphragm 12 is positioned in the ventilation pipe 11 and partitions the inner space of the ventilation pipe 11 into a first air flow passage and a second air flow passage, and the first air flow passage and the second air flow passage are independent from each other. The first air flow channel and the second air flow channel are respectively arranged along the axial direction of the ventilation pipe 11, the first air inlet 111 and the first air outlet 113 are respectively communicated with the first air flow channel, and the second air inlet 112 and the second air outlet 114 are respectively communicated with the second air flow channel. Thus, when the ventilation pipe 11 is erected above the cultivation area, if the first air inlet 111 is filled with fresh air, the first air flow channel can convey the fresh air above the cultivation area, and convey the fresh air to a plurality of different cultivation areas through the first air outlet 113; if the second air inlet 112 is introduced with fresh air, the second air flow channel may deliver the fresh air above the cultivation area, and deliver the fresh air into a plurality of different cultivation areas through the second air outlet 114.
In the ventilation device for a farm, the inner space of the ventilation pipe 11 is divided into the first airflow channel and the second airflow channel which are independent of each other by the diaphragm 12, and the air in the first airflow channel is discharged through the plurality of first air outlets 113, or the air in the second airflow channel is discharged through the second air outlets 114, so that the air outlet direction of the ventilation pipe 11 can be adjusted according to different air temperatures. For example, when the ventilation pipe 11 is installed in a farm, the second air outlet 114 faces the cultivation area, and the first air outlet 113 faces other directions (for example, faces away from the cultivation area), so that when the air temperature is low (in winter), fresh air can be introduced into the first air flow channel through the first air inlet 111, and the fresh air is discharged from the first air outlet 113 which is not facing the cultivation area; when the air temperature is higher (summer), fresh air can be introduced into the second air flow channel through the second air inlet 112, and the fresh air is discharged from the second air outlet 114 facing the cultivation area, so that the temperature of the livestock and poultry is reduced. Compared with the existing mode that the air outlet direction is fixed, the structure can realize the functions of ventilation and cooling simultaneously.
And, fresh air can be simultaneously fed into the first air flow channel and the second air flow channel through the first air inlet 111 and the second air inlet 112, and the air quantity facing the cultivation area and other directions can be adjusted by adjusting the quantity of the fresh air of the first air inlet 111 and the second air inlet 112, so that the temperature of the livestock and poultry in the cultivation area can be properly reduced.
In one embodiment of the present utility model, the diaphragm 12 is constructed of a flexible material such as a fabric, for example, a gas impermeable cloth, so that the diaphragm 12 may be pneumatically pushed to change configuration. And, the width of the diaphragm 12 is greater than the width of the ventilation pipe 11 and less than or equal to half of the circumferential dimension of the ventilation pipe 11, two ends of the diaphragm 12 in the width direction are respectively connected to the inner wall of the ventilation pipe 11, and when the air pressure in the first air flow channel is greater than that in the second air flow channel, the middle part of the diaphragm 12 protrudes towards the second air flow channel, and the volume of the first air flow channel is greater than that of the second air flow channel, as shown in fig. 3; when the air pressure in the second air flow passage is greater than the air pressure in the first air flow passage, the intermediate portion of the diaphragm 12 protrudes toward the first air flow passage and makes the volume of the second air flow passage greater than that of the first air flow passage, as shown in fig. 2.
For example, when the cross section of the ventilation tube 11 is circular (i.e., the ventilation tube 11 is in a circular tube shape), the width of the diaphragm 12 is greater than the diameter of the ventilation tube 11 and less than half of the circumference of the ventilation tube 11, and both ends of the diaphragm 12 in the width direction are respectively fixed at positions adjacent to 180 ° on the inner wall of the ventilation tube 11, the diameter of the ventilation tube 11 may be 30 to 100cm. In particular, in order to increase the ventilation amount, the width of the diaphragm 12 may be equal to or slightly smaller than half of the circumference of the ventilation pipe 11, so that when only the second air inlet 112 is introduced with fresh air (the ventilation pipe 11 is erected above the cultivation area in a manner that the second air outlet 114 is downward), the diaphragm 12 is pushed in a direction away from the first air outlet 113 due to the air pressure in the second air flow channel being far greater than the air pressure in the first air flow channel, so that the diameter of the second air flow channel is close to the diameter of the ventilation pipe 11, and the fresh air in the second air flow channel is discharged to the cultivation area through the second air outlet 114 and is cooled down for the cultivation area and the livestock and poultry in the cultivation area by air cooling; when fresh air is introduced into the first air inlet 111 (the ventilation pipe 11 is also erected above the cultivation area in a downward manner through the second air outlet 114), the air pressure in the first air flow channel is far greater than the air pressure in the second air flow channel, so that the diaphragm 12 is pushed to a direction away from the second air outlet 114, the diameter of the first air flow channel is close to the diameter of the ventilation pipe 11, and the fresh air in the first air flow channel is discharged to the upper side of the cultivation area through the first air outlet 113, so that the livestock and poultry in the cultivation area are prevented from being blown by air. Of course, in practical applications, the ventilation pipe 11 may take other shapes, for example, its cross section may be square, etc.
In order to improve the consistency of the air outlet direction of the ventilation pipe 11, so as to cool down the livestock and poultry in the cultivation area better, the plurality of second air outlets 114 are arranged in a row on the pipe wall of the ventilation pipe 11, that is, the plurality of second air outlets 114 face the same direction, and when the ventilation pipe 11 is installed above the cultivation area in the cultivation farm, the plurality of second air outlets 114 face downwards. Thus, when the second air inlet 112 is introduced with fresh air, the second air outlet 114 can directly blow the fresh air to the livestock and poultry in the cultivation area.
Similarly, the first air outlets 113 may be arranged in a row on the wall of the ventilation pipe 11, and the first air outlets 113 are oriented opposite to the second air outlets 114. Thus, in winter, the cold air outside the air ventilation process can be prevented from being directly blown to the livestock and poultry in the cultivation area.
In one embodiment of the present utility model, as shown in fig. 4, in order to make as much fresh air as possible be blown toward the cultivation area, a plurality of air guide pipes 115 may be provided at the outer wall of the ventilating pipe 11, and the inlet of each air guide pipe 115 is connected to a second air outlet 114. The air duct 115 may be made of the same material as the ventilation duct 11, for example, when the ventilation duct 11 is made of a fabric, the air duct 115 is also made of a fabric.
In one embodiment of the present utility model, to save cost and facilitate erection above the cultivation area, the ventilation tube 11 and the membrane 12 are each formed of flexible fabric, e.g. the ventilation tube 11 is a cloth bag air tube, and the membrane 12 is sewn to the cloth bag air tube. Of course, in practical applications, the ventilation tube 11 may be made of other materials, for example, a hard plastic tube may be used, but the cost is relatively high and the installation difficulty is relatively high.
In one embodiment of the present utility model, the first air inlet 111 and the second air inlet 112 may be located at the same end of the ventilation pipe 11. Correspondingly, the farm ventilation device comprises the ventilation pipe 11 and the diaphragm 12, and also comprises the air compressor 13 and the joint assembly, wherein the joint assembly comprises a main air pipe 141, a branch pipe 142, a first switch valve 143 for controlling the on-off of the branch pipe 142, and a second switch valve 144 for controlling the on-off of the main air pipe 141, the air inlet end of the main air pipe 141 is communicated with the air outlet of the air compressor 13, the air outlet end of the main air pipe 141 is communicated with the second air inlet 112 of the ventilation pipe 11, the air inlet end of the branch pipe 142 is connected to the side wall of the main air pipe 141 (the connecting point is positioned at the front section of the second switch valve 144), and the air outlet end of the branch pipe 142 is communicated with the first air inlet 111 of the ventilation pipe 11. In this way, the fresh air from the outside can be sent to the main air duct 141 through the air compressor 13, and the fresh air can be controlled to enter the first air flow channel and/or the second air flow channel by controlling the on-off of the first switch valve 143 and the second switch valve 144, so as to control the air outlet direction of the ventilation pipe 11. The main air duct 141 and the branch pipe 142 may be made of hard materials, and the first switch valve 143 and the second switch valve 144 may be existing air duct valves, which are not described herein.
In particular, the first air inlet 111 is located at a side wall of the ventilation pipe 11, and the first air inlet 111 of the ventilation pipe 11 has a first socket portion, and the first air inlet 111 is connected to the branch pipe 142 through the first socket portion sleeved to the air outlet end of the branch pipe 142. Similarly, the second air inlet 112 is located at an end of the ventilation pipe 11, and the second air inlet 112 of the ventilation pipe 11 has a second socket portion, and the second air inlet 112 is communicated with the main air pipe 141 through the second socket portion sleeved to the air outlet end of the main air pipe 141. Moreover, a filter screen may be disposed at the first air inlet 111 and the second air inlet 112 to prevent external insects and the like from entering the cultivation area.
In one embodiment of the present utility model, the dimensions of the first air outlet 113 and the second air outlet 114 are smaller than the cross-sectional dimensions of the ventilation pipe 11, the dimensions of the first air inlet 111 and the second air inlet 112 are equal to the cross-sectional dimensions of the ventilation pipe 11, and the end of the ventilation pipe 11, which is far from the end of the second air inlet 112, is closed.
