Description

Technical Field

[0001] This utility model relates to the field of livestock housing technology, and in particular to energy-saving shed-type livestock housing in cold regions. Background Technology

[0002] In cold regions like Heilongjiang, winters are long and harsh, with temperature differences between indoors and outdoors exceeding 50 degrees Celsius, sometimes even 60 degrees Celsius. This poses a severe climate challenge to livestock farming, especially pig farming. The cold weather not only affects the growth rate and health of pigs but also significantly increases breeding costs, particularly heating energy consumption.

[0003] Traditional livestock sheds suffer from insufficient thermal resistance in their external insulation structure, failing to maintain adequate internal temperature. Furthermore, traditional ventilation systems directly expel heat from the shed, resulting in significant heat loss—calculated to account for over 70% of total heat loss. This heat loss must be replenished using coal, electricity, or feed, consuming substantial energy and potentially degrading air quality, impacting the pigs' respiratory system and overall health. Therefore, we propose an energy-efficient shed-style livestock shed for cold regions. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an energy-saving livestock shed for cold regions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The cold region energy-saving shed-type livestock shed includes a rectangular shed body connected to the ground by pre-embedded parts. The top outer wall of the shed body is fixedly connected to a support frame. The top surface of the shed body is arc-shaped and an insulated shed roof is fixedly connected to the top surface of the shed body.

[0007] The thickness of the insulated roof is 45cm, and it is made of rock wool and plastic sheeting wrapped around the rock wool.

[0008] Multiple ventilation openings are fixedly connected to both sides of the shed, and the ventilation openings on both sides are arranged in an alternating pattern in the front and back vertical positions.

[0009] As a further improvement of this utility model, a heat recovery structure is provided at the ventilation opening.

[0010] As a further embodiment of this utility model: the heat recovery structure includes a box fixedly connected to the inner wall of one side of the shed, an air inlet B and an air outlet provided on one side of the box, an air inlet A fixedly connected to one side of the shed, and a spiral tube fixedly connected to the inner wall of the top of the box, wherein the inlet and outlet of the spiral tube are respectively connected to the outlet end of the air inlet A and the inlet end of the air outlet by bolts.

[0011] A one-way gas valve is fixedly connected to the outer circumference of the air outlet.

[0012] As a further improvement of this utility model: an inclined baffle is fixedly connected to the inner edge of the top of the box, and a gap of -cm is left between the bottom end of the baffle and the inner bottom wall of the box.

[0013] As a further improvement of this utility model: the ventilation opening is connected to the housing via a conduit;

[0014] A ventilation fan is fixedly connected to the inner wall of the ventilation opening.

[0015] As a further embodiment of this utility model: both sides of the shed are built with external structural walls; a door is fixedly connected to one side of the shed, and windows are distributed on both sides of the door;

[0016] The canopy has a cable routing hole on one side near the top.

[0017] As a further embodiment of this utility model: a manure scraping groove is provided on the bottom inner wall of the shed near both sides, and a bottom plate is laid on the bottom inner wall of the manure scraping groove;

[0018] The top inner wall of the manure scraping ditch is provided with a slatted panel, and the bottom inner wall of the shed above the slatted panel is provided with several partition plates, and the bottom inner wall of the shed is provided with a material trough.

[0019] As a further embodiment of this utility model: a water supply pipe is fixedly connected to one side of the shed located in the pig breeding area, and a water bowl is fixedly connected to one end of the water supply pipe.

[0020] Compared with existing technologies, this utility model provides an energy-saving shed-type livestock house for cold regions, which has the following beneficial effects:

[0021] 1. This cold-region energy-saving shed-style livestock house, with a 45cm thick insulated roof, can ensure sufficient thermal resistance, effectively reduce heat loss, improve the nighttime insulation effect inside the shed in cold regions, and also prevent the accumulation of rain and snow under load, thus improving safety.

[0022] 2. This cold-region energy-saving shed-type livestock house adjusts the circulation time according to the heat inside the shed. When the temperature difference between the inside and outside of the shed is large, the heat recovery mode is activated. The heat recovery structures on the north and south sides face the same wind direction, so that heat inside the shed can be recovered while ventilation is provided. When the temperature difference between the inside and outside of the shed is small and the temperature inside the shed is sufficient, the ventilation mode is activated. At this time, the heat recovery structures on the north and south sides face opposite directions, so as to achieve ventilation inside the shed and improve energy utilization efficiency.

[0023] 3. This energy-saving shed-style livestock house for cold regions controls the ventilation fan to start clockwise, creating negative pressure inside the enclosure. This allows airflow from inlet B to enter the enclosure simultaneously with outflow from inlet A. During this process, when hot air from inside the enclosure enters through inlet B, it fully contacts the spiral tube for heat conduction, then flows through the gap at the bottom of the baffle towards the ventilation fan and is exhausted outside the enclosure. Meanwhile, the external airflow from inlet A enters the spiral tube, and after a long transport process, the warm air is exhausted from the outlet back into the enclosure. This achieves ventilation while simultaneously recovering and reusing heat from inside the enclosure, resulting in energy savings. This structure also eliminates the need for frequent changes to the ventilation fan's direction, making it convenient to use. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Example 1

[0032] Energy-saving livestock sheds in cold regions, such as Figure 1-3 As shown, the structure includes a rectangular canopy 1 connected to the ground via embedded parts 7. The top surface of the canopy 1 is arc-shaped to prevent the accumulation of rain and snow under load, thus improving safety. A 45cm thick insulated roof 2 is fixed to the top surface of the canopy 1 with bolts, thereby improving the insulation efficiency in cold regions.

[0033] The top outer wall of the shed 1 is fixed with a support frame 102 connected to the ground by bolts. It is a light steel frame to ensure the structural stability of the livestock house. Multiple lighting lamps 10 are fixed on both sides of the support frame 102 by bolts to ensure the brightness inside the livestock house.

[0034] Preferably, the insulated roof 2 is made of rock wool and plastic sheeting wrapped around the top and bottom of the rock wool to ensure sufficient thermal resistance.

[0035] Preferably, one side of the embedded part 7 is reinforced with a slope protection 8 to ensure its structural stability.

[0036] Furthermore, both sides of the shed 1 are built with external structural walls 101; a door 6 and windows 4 distributed on both sides of the door 6 are fixed to one side of the shed 1 by bolts to ensure the brightness of the livestock shed.

[0037] Preferably, the shed body 1 has multiple cable routing holes 3 on one side near the top; this facilitates the layout of power transmission and water supply lines.

[0038] Furthermore, multiple ventilation openings 5 ​​are bolted to both sides of the shed 1 (i.e., facing north and south). Each ventilation opening 5 is equipped with a heat recovery structure, referencing patent CN202321431690.7. This heat recovery structure allows for heat recovery from the interior of the shed 1 while providing ventilation. Preferably, as shown... Figure 3 As shown, the ventilation openings 5 ​​on both sides are arranged in an alternating pattern in the front and back vertical positions, without one-to-one correspondence, in order to ensure effective ventilation circulation inside and outside the livestock shed.

[0039] Unlike patent CN202321431690.7, this system adjusts the circulation time based on the heat inside the shed. When the temperature difference between the inside and outside is large, the heat recovery mode is activated, with the heat recovery structures on the north and south sides facing the same wind direction. This allows for heat recovery from the inside of the shed while providing ventilation. When the temperature difference is small and the temperature inside is sufficient, the ventilation mode is activated, with the heat recovery structures on the north and south sides facing opposite directions, thus providing ventilation. Temperature monitoring inside the shed is achieved through a temperature sensor bolted to the inner wall of one side of the shed. The temperature sensor and the heat recovery structure are electrically connected to the control module.

[0040] Furthermore, a manure scraping ditch 13 is excavated downward on the bottom inner wall near both sides of the shed body 1. The bottom inner wall of the manure scraping ditch 13 is covered with a reinforced concrete base plate 1301 to facilitate cleaning of the manure ditch 13. A slatted board 11 is inserted into the top inner wall of the manure scraping ditch 13. Several cement partition boards 12 are stacked on the bottom inner wall of the shed body 1 above the slatted board 11 to separate the pig feeding areas. Feed troughs 14 are stacked on the bottom inner wall of the shed body 1 on both sides of the road to facilitate feeding of pigs, etc.

[0041] Preferably, a water supply pipe 9 connected to an external conduit is bolted to one side of the shed 1 located in the pig feeding area, and an elliptical water bowl 901 is bolted to one end of the water supply pipe 9; so as to provide clean and sufficient drinking water for the pigs.

[0042] In this embodiment, the structure of the shed 1 is the same as that of the prior art, and will not be described again here.

[0043] Working principle: This embodiment uses a 45cm thick insulated roof 2 to ensure sufficient thermal resistance and maintain the nighttime temperature inside the shelter in cold regions. Furthermore, during use, the circulation time is adjusted according to the heat inside the shelter. When the temperature difference between inside and outside is large, the heat recovery mode is activated, with the heat recovery structures on the north and south sides facing the same wind direction. This allows for heat recovery from the interior of the shelter 1 while providing ventilation. When the temperature difference between inside and outside is small and the temperature inside the shelter is sufficient, the ventilation mode is activated, with the heat recovery structures on the north and south sides facing opposite directions, thus achieving ventilation inside the shelter.

[0044] Example 2

[0045] Energy-saving livestock sheds in cold regions, such as Figure 4 As shown, in order to provide another heat recovery structure, this embodiment makes the following improvements based on embodiment 1: The heat recovery structure includes a box 19 fixed to the inner wall of one side of the shed 1 by bolts, an air inlet B17 and an air outlet 20 opened on one side of the box 19, an air inlet A15 fixed to one side of the shed 1 by bolts, and a spiral tube 18 fixed to the inner wall of the top of the box 19 by bolts, and the inlet and outlet of the spiral tube 18 are respectively connected to the outlet end of the air inlet A15 and the inlet end of the air outlet 20 by bolts.

[0046] Preferably, the spiral tube 18 can be made of metal such as copper; it has excellent thermal conductivity.

[0047] Furthermore, an inclined baffle 16 is fixed to the top inner wall edge of the box 19 by bolts, and a gap of 1-3cm is left between the bottom end of the baffle 16 and the bottom inner wall of the box 19.

[0048] Preferably, a gas check valve is fixed to the outer circumference of the air outlet 20 by bolts;

[0049] Furthermore, the ventilation opening 5 is connected to the housing 19 via a duct; a ventilation fan is fixed to the inner wall of the ventilation opening 5 by bolts.

[0050] Working principle: During use, the ventilation fan is turned clockwise, creating negative pressure inside the housing 19. This draws in airflow from inlet B17 into the housing 1 and outflow from inlet A15 into the housing 19 simultaneously. During this process, when the hot air from inside the housing enters through inlet B17, it fully contacts the spiral tube 18 for heat conduction, then flows through the gap at the bottom of the baffle 16 towards the ventilation fan and is exhausted outside the housing 1. Meanwhile, the external airflow entering through inlet A15 enters the spiral tube 18, and after a long transport process, the heated fresh air is discharged into the housing from outlet 20. This achieves both ventilation and heat recovery and reuse. This structure eliminates the need for frequent fan rotation changes, making it convenient to use.

[0051] Experimental Example 1:

[0052] Under 12-hour nighttime conditions in cold regions, the heat loss rate of a 35cm thick insulated roof 2 is 25%, and the wind pressure resistance is 1.2 kPa; the heat loss rate of a 45cm thick insulated roof 2 is 10%, and the wind pressure resistance is 2.5 kPa; the heat loss rate of a 55cm thick insulated roof 2 is 7%, and the wind pressure resistance is 1.8 kPa.

[0053] In summary, after multiple tests, this utility model shows that a 45cm thick insulated roof is more suitable for cold environments.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
