Description

Technical Field

[0001] This utility model belongs to the field of cattle bed technology, and in particular relates to an automatic control inflatable cattle bed device. Background Technology

[0002] In modern livestock farming, cattle bedding serves as a crucial facility for ensuring the rest quality of dairy and beef cattle and improving farming efficiency. Its performance and comfort directly impact the cattle's health, milk production (for dairy cattle), and growth rate (for beef cattle). Traditional cattle bedding is often made of rigid, fixed materials such as concrete and wood. While these beddings are structurally stable, their rigidity prevents them from adapting to the cattle's body curves and weight distribution. Prolonged use can lead to excessive pressure on specific areas of the cattle's body, causing muscle fatigue, joint damage, and other problems, thus affecting the cattle's health and productivity. Furthermore, the lack of cushioning and elasticity in fixed-structure bedding makes cattle susceptible to impacts when lying down and getting up, increasing the risk of injury.

[0003] Compared to traditional hard bedding, inflatable cattle bedding offers a degree of softness and elasticity, reducing pressure on the cattle's bodies and providing a more comfortable resting environment. However, most existing inflatable cattle bedding uses a single-chamber design, filling the entire chamber with gas during inflation. This results in cattle feeling unstable when stepping onto the bedding due to the high and evenly distributed air pressure within the chamber, as if stepping on a drum surface. This makes it difficult for cattle to smoothly enter the bedding for rest, especially for larger or slower-moving cattle. This instability significantly reduces their willingness to enter the bedding, thus lowering its utilization rate. Furthermore, even after the cattle leave the bedding, the high air pressure within the chamber not only wastes energy but may also accelerate the aging of the air cushion material due to prolonged high pressure, shortening the bedding's lifespan.

[0004] To address this problem, we propose an automatic control device for inflatable cow beds. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that when cattle enter an inflatable cot, the high and uniform air pressure in the air chamber makes it feel unstable when the cattle step on it, and to propose an automatic control device for an inflatable cot.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic control device for inflatable cow beds, comprising:

[0008] The air cushion body, made of flexible material, is sealed by heat pressing to form a middle air chamber and two outer air chambers;

[0009] The intermediate air chamber is provided with an air inlet pipe and an exhaust pipe one, and the outer air chamber is provided with an exhaust pipe two;

[0010] A connecting pipe is provided between the intermediate air chamber and the outer air chamber. A one-way valve is installed on both the air inlet pipe and the connecting pipe. An exhaust solenoid valve is installed on the exhaust pipe.

[0011] An air pump, whose output end is connected to the air inlet pipe, is used to inject air into the air cushion body;

[0012] The pressure sensor is installed in the intermediate air chamber;

[0013] The controller is electrically connected to the pressure sensor, air pump, and exhaust solenoid valve.

[0014] Preferably, the width of the joint in the hot-press seal is 8-15 mm.

[0015] Preferably, the fixed inflation pressure of the outer air chamber is 0.25-0.35 MPa.

[0016] Preferably, the second exhaust pipe is equipped with a manual pressure relief valve.

[0017] Preferably, the intermediate air chamber is pre-filled with air at a pressure of 0.11-0.15 MPa.

[0018] Preferably, a reinforcing mesh is fitted into both the intermediate air chamber and the two outer air chambers.

[0019] In summary, the technical effects and advantages of this utility model are as follows: This automatic control inflatable cattle bed device adopts a three-chamber design. The middle chamber is pre-filled with a small amount of gas. When the cattle are about to enter the bed and step into the middle chamber, the air pressure sensor can detect the air pressure change in time without affecting the stability of the cattle stepping on it. The controller controls the air pump to inflate the middle chamber, avoiding the problem of instability caused by the direct filling of air in traditional inflatable beds. This allows the cattle to enter the bed smoothly and easily, increasing the cattle's willingness to enter the bed and the utilization rate of the bed.

[0020] By setting a reasonable air pressure threshold, the air pressure in the middle air chamber can be automatically adjusted according to whether the cow is resting on the bed. When the cow is resting on the bed, the air pressure in the middle air chamber is kept within a suitable range, which can ensure that the cow has sufficient support and avoid discomfort caused by excessive air pressure. At the same time, the outer air chamber maintains a fixed air pressure, providing stable boundary support for the bed, further enhancing the cow's sense of security and comfort on the bed.

[0021] When the cow leaves the bed, the air pressure sensor detects the change in air pressure, and the controller automatically opens the exhaust solenoid valve to release the gas in the intermediate air chamber, restoring the intermediate air chamber to its initial pre-inflated state. This avoids the energy waste caused by traditional air mattresses maintaining a high-pressure state after the cow leaves, and also reduces the risk of the air cushion material being subjected to high pressure for a long time, effectively extending the service life of the device.

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0027] Reference Figure 1-3 An automatic control device for inflatable cow beds includes an air mattress body 1, an air pump 5, an air pressure sensor 4, and a controller 6.

[0028] The air cushion body 1 is made of a flexible material, which is a high-strength polyvinyl chloride coated cloth. When faced with external forces such as friction and compression generated by the daily activities of cattle, it has excellent wear resistance and tear resistance, ensuring that the air cushion body 1 is not easily damaged during long-term use and extending the service life of the device.

[0029] Reference Figure 1-3 The air cushion body 1 is formed by heat-press sealing to form an intermediate air chamber 11 and two outer air chambers 12. The width of the heat-press seal joint is 8-15mm, which divides the air cushion body 1 into multiple air chambers and can effectively disperse the support force. The fixed inflation pressure of the outer air chamber 12 is 0.25-0.35MPa, so that the outer air chamber 12 forms a stable outer fixed support.

[0030] The air pressure sensor 4 is installed in the intermediate air chamber 11. The air pressure sensor 4 can detect the air pressure value in the intermediate air chamber 11. The air pressure sensor 4 is a digital air pressure sensor with a measurement accuracy of ±0.01MPa and a response time of less than 0.5s.

[0031] Reference Figure 1-3 The intermediate air chamber 11 is provided with an air inlet pipe 111 and an exhaust pipe 112. The output end of the air pump 5 is connected to the air inlet pipe 111. The air inlet pipe 111 is used to fill the intermediate air chamber 11 with air. An exhaust solenoid valve 7 is installed on the exhaust pipe 112. The exhaust pipe 112 is used to exhaust the intermediate air chamber 11.

[0032] The controller 6 is electrically connected to the pressure sensor 4, the air pump 5, and the exhaust solenoid valve 7. The controller 6 is a programmable logic controller (PLC). Those skilled in the art can achieve automatic inflation and deflation of the intermediate air chamber 11 by simply programming the controller 6 to control the opening and closing of the air pump 5 and the exhaust solenoid valve 7 according to the pressure change detected by the pressure sensor 4.

[0033] Reference Figure 1-3 A connecting pipe 2 is provided between the intermediate air chamber 11 and the outer air chamber 12. Both the inlet pipe 111 and the connecting pipe 2 are equipped with one-way valves 3. Initially, air is pumped into the intermediate air chamber 11 by the air pump 5. The one-way valve 3 on the connecting pipe 2 only allows gas to flow from the intermediate air chamber 11 to the outer air chamber 12. While the intermediate air chamber 11 is continuously pumped, the outer air chamber 12 is also pumped simultaneously. In this embodiment, the air is pumped until the pressure sensor 4 displays a pressure of 0.3 MPa, indicating that both the intermediate air chamber 11 and the outer air chamber 12 have reached 0.3 MPa. At this point, the air pump 5 is turned off, and the one-way valve 3 on the inlet pipe 111 restricts the outward flow of gas. The intermediate air chamber 11 is pre-pumped in the initial state, with a pre-pumping pressure of 0.11-0.15 MPa. In this embodiment, the intermediate air chamber 11 needs to be vented to 0.12 MPa by controlling the exhaust solenoid valve 7. The intermediate air chamber 11 can adaptively inflate and deflate by detecting air pressure changes on the air pressure sensor 4. When the cow is about to enter the bed and step on the intermediate air chamber 11, the air pressure sensor 4 can detect the air pressure change in time. At the same time, since the intermediate air chamber 11 only contains a small amount of pre-filled gas, when the cow steps on it, the upper part of the intermediate air chamber 11 will be deformed downward until it touches the ground. Therefore, it does not affect the stability of the cow stepping on it. However, the deformation of the intermediate air chamber 11 will increase the air pressure of the small amount of gas stored in the intermediate air chamber 11. When the air pressure sensor 4 detects this air pressure change, the controller 6 controls the air pump 5 to inflate the intermediate air chamber 11, which will lift the cow that has already stopped on the bed. This avoids the problem of instability caused by the direct filling of the traditional air bed, which makes the cow step on it unstable. This allows the cow to enter the bed to rest smoothly and easily, which improves the cow's willingness to enter the bed and the utilization rate of the bed.

[0034] After the cow leaves the bed, the internal air pressure of the intermediate air chamber 11 decreases. When the air pressure sensor 4 detects this change in air pressure, the controller 6 controls the exhaust solenoid valve 7 to release air to the initial state of a small amount of pre-stored gas at 0.12 MPa.

[0035] The outer air chamber 12 is equipped with an exhaust pipe 121, and a manual pressure relief valve is provided on the exhaust pipe 121. Since the outer air chamber 12 always maintains a normal air pressure of 0.3MPa, it is not necessary to control the exhaust frequently. Therefore, the manual pressure relief valve is provided here. The outer air chamber 12 is only released in special circumstances such as recovery or maintenance of the bed.

[0036] The middle air chamber 11 and the two outer air chambers 12 are all fitted with reinforcing mesh 8. The reinforcing mesh 8 is woven from high-strength and corrosion-resistant fiber material. Its mesh structure is uniform and dense, which can evenly distribute the pressure generated when the cattle lie down, and avoid excessive local pressure that could cause deformation or damage to the air cushion body 1. It not only increases the pressure resistance of the air chamber, but also plays a role in fixing the shape of the air cushion body 1.

[0037] Working principle:

[0038] initial state

[0039] When the intermediate air chamber 11 is continuously inflated, the outer air chamber 12 will be inflated at the same time. When the air pressure sensor 4 shows an air pressure of 0.3 MPa, it means that both the intermediate air chamber 11 and the outer air chamber 12 have reached 0.3 MPa. Then, the intermediate air chamber 11 is released to a pre-inflated state of 0.12 MPa by controlling the exhaust solenoid valve 7.

[0040] The cow enters the bed rest stage

[0041] When a cow prepares to enter the bed and steps into the intermediate air chamber 11, the air pressure inside the intermediate air chamber 11 will increase instantly due to the pressure exerted by the cow's weight. The air pressure sensor 4 monitors the air pressure change in the intermediate air chamber 11 in real time. When the air pressure rise exceeds 0.15 MPa, this threshold is set to a reasonable range under the combined effect of pre-inflation air pressure and slight stepping pressure, which can effectively avoid false triggering caused by slight external interference. It is determined that the cow has entered the bed and the signal is transmitted to the controller 6.

[0042] After receiving the signal from the air pressure sensor 4, the controller 6 immediately starts the air pump 5. The air pump 5 injects air into the intermediate air chamber 11 through the air inlet pipe 111. As the air is continuously injected, the air pressure in the intermediate air chamber 11 gradually increases. When the air pressure in the intermediate air chamber 11 reaches 0.25 MPa, the air pressure sensor 4 sends a signal back to the controller 6. Upon receiving the signal, the controller 6 shuts off the air pump 5, stopping the inflation of the intermediate air chamber 11. At this time, the intermediate air chamber 11 and the outer air chamber 12 together provide comfortable and stable support for the cattle. The air pressure in the intermediate air chamber 11 is slightly lower than that in the outer air chamber 12, which ensures the cattle's comfort while preventing instability caused by excessively high air pressure.

[0043] The cow is in the bed resting stage

[0044] During the cow's resting period, the air pressure in the intermediate air chamber 11 may fluctuate due to the cow's slight movements or slow gas leakage. However, as long as the air pressure remains within the range of 0.25 - 0.3 MPa, the controller 6 will not operate the air pump 5 and the exhaust solenoid valve 7, maintaining the current state and ensuring that the cow can continue to enjoy a comfortable resting environment.

[0045] cattle leaving the bed rest stage

[0046] After the cow leaves the bed, the intermediate air chamber 11 no longer bears the weight of the cow, and the air pressure gradually decreases. The air pressure sensor 4 continuously monitors the air pressure of the intermediate air chamber 11. When the air pressure drops below 0.18 MPa, it is determined that the cow has left the bed and the signal is transmitted to the controller 6.

[0047] After receiving the signal, the controller 6 opens the exhaust solenoid valve 7 on the exhaust pipe 112, and the gas in the middle air chamber 11 is discharged through the exhaust pipe 112. As the gas is discharged, the air pressure in the middle air chamber 11 gradually decreases, while the air pressure in the outer air chamber 12 remains unchanged, continuing to provide stable boundary support for the bed.

[0048] When the air pressure in the intermediate air chamber 11 drops to 0.12 MPa, the air pressure sensor 4 detects that the air pressure has reached the initial pre-inflation state and sends a signal back to the controller 6. The controller 6 closes the exhaust solenoid valve 7, completes the deflation process, and returns to the initial state, waiting for the cow to enter the bed next time.

[0049] 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.
