[0033] The present invention is described below based on embodiments. Those skilled in the art should understand that the drawings provided herein are for illustrative purposes and are not necessarily drawn to scale.

[0034] Unless the context clearly requires otherwise, throughout the specification and claims, the words "include", "comprising" and similar words should be interpreted in an inclusive sense rather than an exclusive or exhaustive sense; that is, in the sense of "including but not limited to".

[0035] In the description of the present invention, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0036] The upper and lower directions in this application are described based on the position of the cooling equipment for pig houses in normal use.

[0037] like Figure 1-3 As shown, the present application provides a cooling device for a pig house, which is used to cool sows in lactation. The cooling device 2 includes a square frame structure 21, and the cooling device 2 also includes a cooling component 22 arranged on the frame structure 21. The frame structure 21 includes a first side 211, a second side 212, a third side 213 and a fourth side 214 connected to each other. A plurality of support ribs 215 parallel to the first side 211 are arranged side by side between the second side 212 and the fourth side 214, and a plurality of support portions 216 parallel to the second side 212 are arranged side by side between the first side 211 and the third side 213.

[0038] The frame structure 21 is used to fix and install the cooling component 22. In order to better conduct heat, the cooling component 22 is generally a thin-walled structure with average structural strength. When subjected to huge external tangential force, the cooling component 22 may be damaged. The frame structure 21 can fix and protect the cooling component 22 well, thereby extending the service life of the cooling equipment 2.

[0039] The cooling component 22 includes two connecting parts 221 respectively arranged outside the first side 211 and the third side, and a plurality of cooling parts 222 arranged between the two connecting parts 221 and parallel to the second side 212. The cooling part 222 is connected with the connecting part 221. The cooling component 22 is a structure that mainly plays a cooling role in the cooling device 2. The cooling component 22 exchanges heat with the outside through the cooling part 222, thereby achieving the purpose of cooling. Specifically, the cooling part 222 exchanges heat with the air near the cooling part 222 to reduce the temperature of the nearby air, thereby achieving the effect of slowly reducing the temperature of the entire pig house 1; of course, the cooling part 222 can also achieve the effect of quickly reducing the surface temperature of the pig by directly contacting the pig.

[0040] Furthermore, the support rib 215 is elongated, and a plurality of first accommodating grooves (not shown in the figure) are provided along the length direction of the support rib 215, and at least a portion of the structure of the cooling portion 222 is accommodated in the first accommodating grooves; and / or, a plurality of second accommodating grooves (not shown in the figure) are provided on the first side 211 and the second side 212 of the frame structure 21 connected to the cooling portion 222, and at least a portion of the structure of the cooling portion 222 is accommodated in the second accommodating grooves.

[0041] The first side of the frame structure 21 is flush with the ground, the support portion 216 and the cooling portion 222 are arranged on the first side of the frame structure 21 and are flush with the ground, and the cooling portion 222 is interspersed in the support portion 216. Preferably, the cooling portion 222 is evenly arranged in the support portion 216, which can achieve a better heat exchange effect. For example, a cooling portion 222 is arranged between any two connected support portions 216, or a support portion 216 is arranged between any two adjacent cooling portions 222. Of course, it can be understood that according to the specific design of the pig house 1, the cooling portion 222 in a specific area can also be densely arranged, for example, a more dense cooling portion 222 is arranged in the cooling component 22 in the delivery bed 12 area to achieve a better cooling effect.

[0042] The support part 216 and the reinforcing rib plate and / or the frame structure 21 are not easily damaged and do not need to be disassembled, so they are fixedly connected by welding, which has high structural strength and low cost. Specifically, the support part 216 includes steel bars, and an anti-skid structure is provided on the steel bars to prevent pigs from slipping and falling in the pig house 1; the anti-skid structure includes an embossed structure provided on the surface of the steel bars. More specifically, the cooling part 222 and / or the connecting part 221 include a square tube structure made of stainless steel material.

[0043] Furthermore, a connection port 2211 is provided on the connection part 221, and the connection port 2211 is connected to the water supply device 3. The water in the water supply device 3 enters the connection part 221 through the connection port 2211, and then enters the cooling part 222; a sealing ring is provided at the connection port 2211 and the water supply device 3 to achieve a better connection effect and prevent cooling water from overflowing, corroding the connection port 2211, and affecting the airtightness of the connection port 2211; the connection port 2211 is arranged on the side of the connection part 221 opposite to the first side of the frame structure 21.

[0044] A control valve (not shown in the figure) is provided at the connection port 2211. The control valve can control the opening and closing of the connection port 2211. When the control valve is opened, the water in the water supply device 3 enters the connection part 221 through the connection port 2211, and then enters the cooling part 222, so that the cooling part starts to exchange heat with the outside and performs cooling work; when the control valve is closed, the water supply device 3 is blocked from the connection port 2211, and the cooling water cannot enter the connection part 221. No cooling water flows into the cooling part 222, and the cooling work is not performed. The cooling device also includes a control device (not shown in the figure) and a temperature detection device (not shown in the figure). The temperature detection device is arranged in the pig house 1 and connected to the control device. The control device is connected to the control valve and can control the switch of the control valve. The control device includes an automatic control mode. In the automatic control mode, the control device receives the ambient temperature information detected by the temperature detection device and automatically controls the control valve to open when the ambient temperature information is higher than the predetermined temperature, so as to cool the pig house 1. Of course, it is understandable that due to the different breeds, characteristics and feeding stages of pigs, the temperature requirements are also different. The breeder needs to determine whether the system should be turned on to cool down the pig house 1 based on experience. Therefore, the control device also includes a manual control mode. In the manual control mode, when the control device receives the ambient temperature information detected by the temperature detection device, it conveys the information to the breeder. When the ambient temperature information is higher than the predetermined temperature, a reminder is issued to the breeder, and the breeder decides whether to turn on the refrigeration system of the pig house 1 to cool down the pig house 1.

[0045] The cooling device 2 further includes a spray structure 23, which rapidly cools the pigs by spraying cooling water directly on the pigs. The spray structure 23 is arranged on the connection part 221 and is perpendicular to the connection part 221. The spray structure 23 is located on the first side of the frame structure 21. The spray structure 23 is connected to the connection part 221. A water pump (not shown in the figure) is arranged between the spray structure 23 and the connection part 221. The water pump is used to pump water in the connection part 221 into the spray structure 23 for spraying. Preferably, the water pump is also connected to the control device, and the control device can control the water pump to thereby realize the control of opening and closing of the spray structure 23.

[0046] Specifically, the spray structure 23 includes at least two, the spray structure 23 is arranged at the end of the connecting portion 221, the spray structure 23 is a cylindrical tube or a square tube, and a plurality of spray holes 231 are arranged along the circumferential direction and the axial direction of the spray structure 23; an atomizing nozzle is arranged on the spray hole 231, and the atomizing nozzle is used to convert the water in the spray structure 23 into a mist state for spraying; or, an atomizing fan (not shown in the figure) is arranged on the spray hole 231 at one end of the frame structure 21 of the spray structure 23, and the atomizing fan is used to convert the water in the spray structure 23 into a mist state for spraying while driving the airflow around it to accelerate the flow.

[0047] The cooling equipment for pig houses in the present application can cool down the pig houses in a variety of ways by setting up cooling equipment, and can automatically control the start and stop of the equipment according to changes in ambient temperature, thereby realizing automated cooling of the pig houses and solving the problem of excessively high ambient temperature in the pig houses caused by high temperatures in summer. The effect is significant and the cost is low, and it is recommended to be promoted and used on a large scale.
