Description

Technical Field

[0001] This utility model relates to the field of beef cattle breeding technology, and in particular to a ventilation device for cattle sheds used in beef cattle breeding. Background Technology

[0002] The roofs of most existing cattle sheds are made of corrugated steel sheets. However, when corrugated steel sheets with insulation are exposed to the sun in summer, the temperature inside the cattle shed will rise. Ventilation of the cattle shed is generally to remove the unpleasant gases inside and to cool down the cattle shed.

[0003] According to the patent document with announcement number CN222170802U, by controlling the operation of the electric push rod, the first baffle and the second baffle are driven to rotate around the shaft to realize the opening and closing function. The ventilation window at the first baffle allows air to enter and the natural wind can be directed downwards through the first baffle, while the second baffle can direct the air at the top of the cowshed to be discharged.

[0004] The patent document states that when ventilating a cattle shed, it is necessary to control the opening and closing of the first and second baffles to achieve ventilation on the upper side or throughout the shed. In the hot summer, the outside air temperature will also rise to a certain extent, and direct sunlight on the shed roof will further increase the internal temperature of the cattle shed. Simply relying on ventilation is obviously not enough to alleviate the high temperature inside the cattle shed. Summary of the Invention

[0005] The purpose of this invention is to provide a ventilation device for cattle sheds used in beef cattle farming in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A ventilation system for cattle sheds used in beef cattle farming includes a cattle shed, a cooling mechanism and a ventilation mechanism. The cooling mechanism is located on the top of the cattle shed, and the ventilation mechanism is located on the top of the cattle shed.

[0008] The cooling mechanism includes a water spray pipe, which is fixed at the top of the cattle shed. Multiple nozzles are fixed on both sides of the water spray pipe, a water supply pipe is fixed at the front end of the water spray pipe, and a ball valve is fixed at the lower end of the water supply pipe.

[0009] The ventilation system includes an air outlet duct, which is fixed to the roof inside the cattle shed. Isolation plates are fixed on both sides of the air outlet duct. The air outlet duct, the two isolation plates, and the roof of the cattle shed form a flow guide cavity. Multiple air inlet ducts are fixed to the ends of the two isolation plates that are far apart from each other. An air supply duct is fixed in the middle of each air inlet duct. A guide duct is fixed to the end of the multiple air supply ducts that is far away from the air inlet ducts. A blower is fixed to both ends of the guide duct. An air supply protective net plate is fixed to the blower. The end of the air supply duct that is far away from the guide duct faces the upper end of the air inlet duct.

[0010] Preferably, the water spray pipe and the water supply pipe are interconnected, and multiple threaded holes for installing nozzles are opened on both sides of the water spray pipe.

[0011] Preferably, each air inlet pipe has an air inlet at its lower end, and each air inlet is fixed with an air inlet protective mesh plate. The bottom of the air outlet pipe has multiple air holes for exhausting air from the guide cavity.

[0012] Preferred configuration: The isolation panel is fixedly connected to the roof of the cattle shed, and the upper end of the air inlet pipe is connected to the guide cavity.

[0013] Preferably, the air duct and the air supply duct are interconnected, and the air inlet duct and the air supply duct are interconnected.

[0014] Preferred configuration: Multiple air outlets are provided on both sides of the bottom of the cattle shed, and each air outlet is equipped with an activated carbon filter and multiple longitudinally distributed air outlet grilles.

[0015] Preferably, multiple air outlet grilles are located outside the air outlets of the cattle shed, and activated carbon filters are located inside the air outlets of the cattle shed.

[0016] The advantages compared to existing technologies are as follows:

[0017] 1. Air is blown into the guide cavity from the air supply duct by the blower. The air flow creates suction on the lower side of the air inlet duct, so that the air drawn in from the lower end of the air inlet duct is sent into the guide cavity along with the air blown out from the air supply duct, thereby increasing the amount of air entering the guide cavity and indirectly improving the ventilation of the entire cowshed.

[0018] 2. Use a cooling device to spray water onto the roof of the cattle shed. The temperature of the roof will be reduced by the evaporation of water. At the same time, the air flow in the drainage cavity will also carry away some of the temperature from the roof, thus cooling the cattle shed to a certain extent in the hot summer.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The present invention will be further described below with reference to the accompanying drawings:

[0033] like Figures 1-9 As shown, a cattle shed ventilation device for beef cattle breeding includes a cattle shed 1, characterized in that: it also includes a cooling mechanism 2 and a ventilation mechanism 3, the cooling mechanism 2 is provided on the top of the cattle shed 1, and the ventilation mechanism 3 is located on the top of the cattle shed 1.

[0034] In this embodiment: the cooling mechanism 2 includes a water spray pipe 23, which is fixed at the top of the cattle shed 1. Multiple nozzles 24 are fixed on both sides of the water spray pipe 23. A water supply pipe 21 is fixed at the front end of the water spray pipe 23, and a ball valve 22 is fixed at the lower end of the water supply pipe 21. In the hot summer, water is sent into the water supply pipe 21 through an external water pipe, and then evenly sprayed onto the top of the cattle shed 1 through the nozzles 24 on the water spray pipe 23. The temperature of the top of the cattle shed 1 is absorbed by the evaporation of water, and the temperature inside the cattle shed 1 is further reduced by the air flow.

[0035] In this embodiment: the ventilation mechanism 3 includes an air outlet pipe 39, which is fixed to the roof inside the cowshed 1. Isolation plates 4 are fixed to both sides of the air outlet pipe 39. The air outlet pipe 39, the two isolation plates 4, and the roof of the cowshed 1 form a flow guide cavity. Multiple air inlet pipes 37 are fixed to the ends of the two isolation plates 4 that are far apart from each other. An air supply oblique pipe 38 is fixed to the middle of each air inlet pipe 37. An air guide pipe 36 is fixed to the end of each air supply oblique pipe 38 that is far away from the air inlet pipe 37. Both ends of the air guide pipe 36 are fixed with… A blower 35 is equipped with a blower protective mesh plate 34. The end of the blower 38 away from the guide pipe 36 faces the upper end of the inlet pipe 37. A water spray pipe 23 is connected to a water supply pipe 21. Multiple threaded holes for installing nozzles 24 are provided on both sides of the water spray pipe 23. Each inlet pipe 37 has an air inlet at its lower end, and an air inlet protective mesh plate 33 is fixed at each air inlet. The bottom of the outlet pipe 39 has multiple air holes for exhausting air from the guide cavity. The guide pipe 36 and the blower 38 are connected... The air inlet pipe 37 and the air supply inclined pipe 38 are interconnected. The isolation plate 4 is fixedly connected to the roof of the cowshed 1. The upper end of the air inlet pipe 37 is connected to the guide cavity. The blower 35 blows outside air into the air supply pipe 36, and then the two air supply pipes 36 send the air into multiple air supply inclined pipes 38. The multiple air supply inclined pipes 38 blow the air into the guide cavity at the upper end of the air inlet pipe 37. The air in the guide cavity will flow from both sides to the air outlet pipe 39, and then the air in the guide cavity will flow out of the air outlet pipe. Air flows into the lower side of the air vent 39, thereby supplying air into the cowshed 1. In addition, when air flows into the air inlet pipe 37 from the air supply duct 38, since the upper end of the air supply duct 38 faces the connection position between the air inlet pipe 37 and the isolation plate 4, according to Bernoulli's principle, as the air velocity delivered by the air supply duct 38 increases, a suction force will be formed at the air inlet protective mesh plate 33 on the lower side of the air inlet pipe 37, thereby increasing the amount of air entering the guide cavity. At the same time, the air inlet protective mesh plate 33 is used to prevent mosquitoes from flying into the cowshed 1.

[0036] In this embodiment: multiple air outlets are provided on both sides of the bottom of the cowshed 1. Each air outlet is provided with an activated carbon filter 32 and multiple longitudinally distributed air outlet grilles 31. The multiple air outlet grilles 31 are located outside the air outlets of the cowshed 1, and the activated carbon filter 32 is located inside the air outlets of the cowshed 1. As the air outlet 39 continuously sends air into the cowshed 1, the air outlets on both sides of the cowshed 1 are used to exhaust the original air. When the original air in the cowshed 1 is exhausted, the activated carbon filter 32 adsorbs and removes the odor in the original air.

[0037] Working principle: In use, firstly, four blowers 35 blow outside air into the air duct 36, and then;

[0038] Furthermore, when air flows from the air supply duct 38 into the guide cavity, since the upper end of the air supply duct 38 faces the connection position between the air inlet duct 37 and the isolation plate 4, according to Bernoulli's principle, as the air velocity delivered by the air supply duct 38 increases, a suction force will be formed at the air inlet on the lower side of the air inlet duct 37, thereby drawing outside air from the air inlet protective mesh plate 33 into the air inlet duct 37, and then sending it into the guide cavity through the air inlet duct 37, thereby increasing the amount of air entering the guide cavity and improving ventilation efficiency. In addition, the air inlet protective mesh plate 33 prevents mosquitoes from flying into the cowshed 1. As the air outlet duct 39 continuously delivers air into the cowshed 1, the air outlets on both sides of the cowshed 1 are used to exhaust the original air outward. When exhausting the original air in the cowshed 1, the activated carbon filter 32 adsorbs and removes the odor in the original air.

[0039] When the weather is hot in summer, water is sent into the water supply pipe 21 through the external water pipe and sprayed evenly onto the roof of the cowshed 1 through the nozzle 24 on the spray pipe 23. The evaporation of water absorbs the temperature of the roof of the cowshed 1, and the air flowing in the guide cavity further reduces the temperature inside the cowshed 1.

[0040] During winter, the air in the drainage cavity reduces heat loss from the roof of the cowshed 1, thus improving the overall insulation effect of the cowshed 1.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
