Description

Technical Field

[0001] This utility model relates to the field of aquaculture environment control technology, and in particular to an environment control device for beef cattle breeding sheds with intelligent temperature control and ventilation functions. Background Technology

[0002] In beef cattle farming, the environmental conditions within the barn directly affect the cattle's growth rate, health status, and meat quality. Beef cattle growth depends on the regulation of multiple environmental factors, including temperature, humidity, and air circulation. Environmental control is particularly crucial in modern large-scale farming. Suitable temperature and humidity can reduce stress responses in cattle, lower the likelihood of disease, and promote growth and development. Conversely, poor environmental conditions, such as polluted air, poor ventilation, or excessive humidity, can easily lead to difficulties in thermoregulation, respiratory diseases, and slow weight gain in cattle.

[0003] In the prior art, for example (authorization announcement number CN208654666U), a greenhouse environment control device is disclosed. Through temperature sensors, humidity sensors, and air quality sensors, the device can detect the temperature, humidity, and air quality in the breeding shed. The detected data is transmitted to a processor, which analyzes and processes the data and controls the central temperature-controlled air conditioner and ventilation fans to regulate the environment in the breeding shed, so that the breeding shed is always in a comfortable breeding environment, which is conducive to reducing the disease rate of sheep and is suitable for widespread promotion and use.

[0004] Although existing technologies involve environmental control, they mainly focus on intelligent temperature and humidity regulation and do not fully solve the problem of air circulation in the breeding shed. Especially in large-scale breeding environments, poor air circulation and uneven temperature and humidity in local areas are still important factors affecting breeding results. Therefore, this utility model proposes an environmental control device for beef cattle breeding sheds with intelligent temperature control and ventilation functions to solve the problems existing in the existing technology.

This device has the advantages of creating good airflow circulation and improving the air quality at the bottom of the shed, thus solving the problems in the prior art.

[0006] To achieve the purpose of this utility model, the following technical solution is provided: an environmental control device for beef cattle breeding sheds with intelligent temperature control and ventilation functions, comprising an internal exhaust duct and an electrical control cabinet. External air inlet ducts are installed on both sides of the internal exhaust duct, and the cross-section of the internal exhaust duct is annular. Two sets of symmetrically arranged exhaust chambers are provided on the inner side of the internal exhaust duct. An extension pipe is installed at the lower end of the external air inlet duct, and several sets of extension pipes are provided. Air inlet components are installed on the extension pipes, and several sets of air inlet components are arranged sequentially from top to bottom. A relay pipe is installed at one end of the external air inlet duct. An exhaust component is installed at the lower end of the internal exhaust duct. Both the exhaust component and the air inlet component are electrically connected to the electrical control cabinet. A main air box is installed on the inner side of the internal exhaust duct via a connecting pipe. The main air box has an exhaust port and an air inlet. A temperature and humidity sensor is installed on the extension pipe and is electrically connected to the electrical control cabinet. One end of the relay pipe passes through the internal exhaust duct and is connected to the main air box.

[0007] A further improvement is that: two sets of symmetrically arranged heat-conducting baffles are installed inside the main air box, and the two sets of heat-conducting baffles divide the main air box into two sets of symmetrically arranged air inlet chambers and air outlet chambers. There are two sets of air inlets, which correspond to the positions of the two sets of air inlet chambers respectively, and the position of the air outlet corresponds to the air outlet chamber.

[0008] A further improvement is that both the air intake assembly and the air exhaust assembly include an outer cylinder, which is connected to the corresponding inner exhaust duct and outer air intake duct. An electric fan and a protective net are installed on the inner side of the outer cylinder.

[0009] A further improvement is that an electric heating tube is installed on the inner side of the extension tube, and the electric heating tube is provided in several groups, and the several groups of electric heating tubes are electrically connected to the electrical control cabinet.

[0010] A further improvement is that a guide tube is provided on the outside of the air inlet, the guide tube is fixedly connected to the main air box, and a dustproof net is installed on the inside of the guide tube by bolts.

[0011] A further improvement is that a wind speed sensor is installed on the inner side of the outer cylinder, and the wind speed sensor is electrically connected to the electrical control cabinet.

[0012] A further improvement is that the electrical control cabinet is equipped with a PLC controller and a power supply.

[0014] The beneficial effects of this invention are as follows: This environmental control equipment for beef cattle sheds with intelligent temperature control and ventilation functions, through the combination of internal exhaust ducts, external air intake ducts, and extension pipes, adopts a bottom-supply and top-exhaust air circulation method, which is conducive to forming good airflow circulation in the shed, thereby improving the air quality at the bottom of the shed. Simultaneously, the extension pipes allow for air supply to different areas and heights within the shed, thus improving the environmental uniformity. Furthermore, the use of heat-conducting partitions and a main air box effectively recovers waste heat from exhaust air while physically isolating the intake and exhaust air, significantly reducing heating energy consumption in winter. In addition, this invention uses a PLC controller as the control core, combined with temperature and humidity sensors and wind speed sensors, to achieve intelligent control of temperature and ventilation.

[0021] To enhance understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are for illustrative purposes only and do not constitute a limitation on the scope of protection of this utility model.

[0022] according to Figures 1-4 As shown in the figure, this embodiment proposes an environmental control device for beef cattle farms with intelligent temperature control and ventilation functions. It includes an internal exhaust duct 1 and an electrical control cabinet 2. The electrical control cabinet 2 houses a PLC controller and a power supply, which provides power to all electronic components of the device. Correspondingly, the PLC controller has a preset temperature and humidity control strategy, i.e., preset temperature and humidity thresholds to trigger ventilation. Based on the comparison between the actual values ​​transmitted by the temperature and humidity sensors 11 and the preset thresholds, the power of the electric heating element 18 and the speed of the electric fan 16 are adjusted. For example, the heating power is increased when the temperature is too low, and the fan speed is increased when the temperature is too high. Thus, through the cooperation of the PLC controller and sensors, the intelligent temperature control and ventilation functions are achieved.

[0023] Both sides of the internal exhaust duct 1 are equipped with external air inlet ducts 3. The lower end of the external air inlet duct 3 is equipped with an extension pipe 5, and the extension pipe 5 is provided with several sets. An air inlet component is installed on the extension pipe 5, and the air inlet component is provided with several sets from top to bottom. In this embodiment, during the use of this equipment, the internal exhaust duct 1 is installed at the top of the breeding house 22. Its function is to exhaust the hot air in the upper part of the breeding house 22. The extension pipe 5 is used to send fresh air from outside into the breeding house 22, so as to realize differentiated air supply adjustment in different areas and different heights inside the house and improve the environmental uniformity.

[0024] like Figure 1 As shown, the internal exhaust duct 1 has a ring-shaped cross-section. Two sets of symmetrically arranged exhaust chambers 4 are located inside the internal exhaust duct 1, and the two sets of exhaust chambers 4 do not interfere with each other. An exhaust assembly is installed at the lower end of the internal exhaust duct 1, and the position of the exhaust assembly corresponds to the position of the exhaust chamber 4. Both the exhaust assembly and the inlet assembly are electrically connected to the electrical control cabinet 2. Both the inlet and exhaust assemblies include an outer cylinder 15, which has several sets. The outer cylinder 15 is connected to the corresponding internal exhaust duct 1 and external inlet duct 3. An electric fan 16 and a protective net 17 are installed inside the outer cylinder 15. The protective net 17 is located at the airflow inlet (outlet) end and uses a stainless steel perforated mesh with a hole diameter ≤5mm to prevent foreign objects from entering. Simultaneously, a wind speed sensor is installed inside the outer cylinder 15, electrically connected to the electrical control cabinet 2, and installed close to the air outlet side of the electric fan 16 to monitor the actual airflow in real time and feed it back to the electrical control cabinet 2. Correspondingly, the function of the electric fan 16 in the internal exhaust duct 1 is to exhaust the air in the breeding house 22, and the function of the electric fan 16 in the extension pipe 5 is to draw in the outside air and deliver it to the breeding house 22.

[0025] Correspondingly, staff can preset the wind speed threshold in the PLC controller. When the wind speed sensed by the wind speed sensor is lower than the set threshold, the PLC controller increases the frequency output of the inverter of the corresponding electric fan 16 until the wind speed reaches the standard.

[0026] The inner side of the internal exhaust duct 1 is connected to a main air box 8 via a connecting pipe 7. The main air box 8 is equipped with an exhaust port 9 and an air inlet 10. There are two sets of air inlets 10, which correspond to the positions of the two sets of air inlet cavities 13. The position of the exhaust port 9 corresponds to the exhaust cavity 14. A rain cover 23 is installed on the upper end of the exhaust port 9. The lower end of the rain cover 23 is fixedly connected to the main air box 8 via a bracket. The rain cover 23 is open to the outside environment on all sides to facilitate the exhaust of air.

[0027] A relay pipe 6 is installed at one end of the external air intake duct 3. One end of the relay pipe 6 passes through the internal exhaust duct 1 and connects to the main air box 8, thereby connecting the inner cavity of the external air intake duct 3 with the main air box 8. Furthermore, two sets of symmetrically arranged heat-conducting baffles 12 are installed inside the main air box 8, dividing the main air box 8 into two symmetrically arranged air intake cavities 13 and exhaust cavities 14. Specifically, the inner cavity of the external air intake duct 3 is connected to the inner cavity of the extension pipe 5, and the inner cavity of the external air intake duct 3 is also connected to the corresponding air intake cavity 13 via the relay pipe 6. Thus, the electric fan 16 of the air intake assembly drives the airflow from the air inlet 10 into the air intake cavity 13, then through the relay pipe 6 into the external air intake duct 3, and finally into the extension pipe 5, and then delivers air into the breeding shed 22. Similarly, the electric fan 16 of the exhaust assembly sends the air in the breeding house 22 into the exhaust chamber 4, then into the exhaust inner chamber 14 through the connecting pipe 7, and then out through the exhaust port 9.

[0028] For the main air box 8, while physically isolating the intake and exhaust air, it effectively recovers the waste heat of the exhaust air, significantly reducing the energy consumption for winter heating. That is, the hot and cold air flows in opposite directions on both sides of the partition 12, thereby achieving heat transfer in the process, which in turn preheats the incoming fresh air.

[0029] A temperature and humidity sensor 11 is installed on the extension tube 5 and is electrically connected to the electrical control cabinet 2. The detection end of the temperature and humidity sensor 11 extends into the airflow section in the center of the extension tube 5, and it plays a role in monitoring temperature and humidity. For example, when the detected air supply temperature is lower than the set lower limit, the electric heating tube 18 is activated and its power is increased, while the speed of the electric fan 16 of the air supply component is reduced to reduce heat loss.

[0030] An electric heating element 18 is installed inside the extension tube 5. Several groups of electric heating elements 18 are provided, and these groups of electric heating elements 18 are electrically connected to the electrical control cabinet 2. This is used to heat the incoming fresh air when the temperature does not meet the requirements.

[0031] A guide tube 19 is provided on the outside of the air inlet 10. The guide tube 19 is fixedly connected to the main air box 8, and a dustproof net 20 is installed on the inside of the guide tube 19 by bolts. The function of the guide tube 19 is to cooperate with the dustproof net 20 to filter dust from the incoming fresh air.

[0032] A mounting bracket 21 is installed on the internal exhaust duct 1 and the external intake duct 3. Through the cooperation of the mounting bracket 21 and bolts, the internal exhaust duct 1 and the external intake duct 3 are installed on the top of the breeding shed 22. It should be noted that an opening is needed in the top of the breeding shed 22 to accommodate the passage of the main air box 8. Furthermore, condensate drain pipes are installed at the lower ends of both the extension pipe 5 and the main air box 8 to facilitate the drainage of condensate generated within the pipes.

[0033] 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.
