Description

Technical Field

[0001] This invention relates to the field of data acquisition technology, specifically to a real-time data acquisition device for piglet diarrhea information. Background Technology

[0002] Pigs are vertebrates, mammals, and livestock. They are also ancient omnivorous mammals, mainly divided into domestic pigs and wild boars. Currently, the term "pig" is considered a general term for animals in the Suidae family. Pigs vary in appearance depending on the breed; they are typically characterized by large ears, long heads, short limbs, straight noses, stout bodies, and narrow backs. Their hair is relatively coarse, and their coat colors are usually white, pink, black, brown, or spotted. Domestic pigs are a subspecies of wild boar that has been domesticated by humans. They have shorter tusks than wild boars and are one of the domesticated livestock.

[0003] In piglet rearing, to reduce mortality, measures such as vaccination and adding antibiotics to feed are commonly used. Besides medication, real-time monitoring and management of piglet production are essential for timely problem detection. For example, if diarrhea is not detected promptly, it can damage the piglets' gastrointestinal health, leading to reduced nutrient conversion rates, slow growth, or even stunted growth, which is extremely detrimental to piglet rearing. Existing data collection devices, designed to better capture information about piglet diarrhea, typically have height adjustment functions. However, frequent washing in pig farms allows moisture to easily enter the height adjustment mechanism, causing rust and affecting the internal lubricating grease. Summary of the Invention

[0029] The following will describe in detail the implementation of the present invention with reference to the accompanying drawings and embodiments, so that the process of how the present invention uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0030] In the description of this invention, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention 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. They should not be construed as limiting the specific protection scope of this invention.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature, and in the description of this invention, "a number" means two or more, unless otherwise explicitly specified.

[0032] In this invention, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or 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 invention according to the specific circumstances.

[0033] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0034] It should also be understood that the terminology used in this specification of embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the invention. As used in this specification of embodiments of the invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0035] As shown in the accompanying drawings, a real-time information collection device for piglet diarrhea includes a mounting frame and several monitoring cameras 2, wherein the monitoring cameras 2 are mounted on the mounting frame; the mounting frame includes a base 6, a lifting rod, a drive assembly, a mounting box 1, and a fixing column 5.

[0036] The fixing column 5 is vertically and detachably mounted on the base 6. The fixing column 5 is provided with an axial movable hole 13 that cooperates with the lifting rod. The mounting box 1 is located at the upper end of the lifting rod and is used to install the monitoring camera 2.

[0037] The drive assembly is installed inside the fixed column 5 to drive the lifting rod to move up and down relative to the fixed column 5.

[0038] A sealing assembly for sealing is provided in the movable hole 13. The sealing assembly includes a sealing ring 29, a drive ring 28, and a spring 26. The wall of the movable hole 13 is provided with a mounting groove for installing the sealing ring 29. The fixed post 5 is provided with an annular groove 27 that communicates with the mounting groove. The drive ring 28 and the spring 26 are disposed in the annular groove 27. The inner wall surface of the drive ring 28 is a conical surface 30, and the outer wall surface of the sealing ring 29 is a conical surface 2 that mates with the conical surface 30. One end of the spring 26 is fixedly connected to the bottom of the annular groove 27, and the other end is fixedly connected to the drive ring 28.

[0039] In the above scheme, spring one applies a downward force to the drive ring, causing tapered surface one and tapered surface two to move relative to each other. Tapered surface one compresses tapered surface two, causing the sealing ring to deform more and thus improving the sealing effect.

[0040] The drive assembly includes a power component and a transmission component. The power component drives the transmission component to move the lifting rod up and down relative to the fixed column 5. Specifically, the power component is a motor 14; the transmission component includes a lead screw 20, and the lifting rod has a threaded hole that mates with the lead screw 20. One end of the lead screw is connected to the motor 14 for transmission. In this design, the lead screw is rotated by electric rotation, thereby causing the lifting rod to move up and down relative to the fixed column 5.

[0041] Those skilled in the art will know that, in the sealed state, the inner wall of the sealing ring is in close contact with the outer circumferential surface of the lifting rod. At this time, there is a large frictional force between the sealing ring and the lifting rod. If the lifting rod is raised or lowered in this state, it is easy to damage the inner wall of the sealing ring and affect the sealing performance of the sealing ring. Therefore, as another embodiment of the present invention, a release component is also included. The release component is disposed in the fixed column 5. The release component is used to drive the drive ring 28 to compress the spring 26, thereby releasing the pressure of the drive ring 28 on the sealing ring 29.

[0042] In this embodiment, specifically, the release assembly includes a linkage component, an annular cavity 33, and an annular piston 34. The annular cavity 33 is disposed within the fixed column 5, and the annular piston 34 is disposed within the annular cavity 33. The annular cavity 33 is connected to the annular groove 27 through a through hole. A connecting rod 35 is disposed within the through hole. One end of the connecting rod 35 is fixedly connected to the annular piston 34, and the other end is fixedly connected to the connecting ring 38 disposed on the outer wall of the drive ring 28. The linkage component is used to drive the lifting rod and the annular piston 34. An air pipe 37 communicating with the outside is disposed within the annular cavity 33, and a pressure relief valve 36 is disposed on the air pipe 37.

[0043] The linkage component includes a connecting rod 18, a guide rod 16, and a cylindrical piston 24. The fixed column 5 has a cylindrical cavity 21 for mounting the cylindrical piston 24 and a movable groove 19 that mates with the guide rod 16. One end of the guide rod 16 is connected to the lifting rod, and the other end is connected to the connecting rod 18. The end of the connecting rod 18 away from the guide rod 16 extends into the cylindrical cavity 21 and is fixedly connected to the cylindrical piston 24. The upper end of the cylindrical cavity 21 is connected to the lower end of the annular cavity 33 via a connecting pipe 32. The connecting pipe 32 is provided with... One-way valve 31 is used to control the unidirectional flow of gas from cylindrical cavity 21 to annular cavity 33. One-way valve 25 is provided on cylindrical piston 24. One-way valve 25 is used to control the unidirectional flow of gas in cylindrical cavity 21 from the lower end to the upper end of cylindrical cavity 21 (that is, when cylindrical piston 1 moves upward, one-way valve 3 is closed, and cylindrical piston 1 forces the air in cylindrical cavity 1 into annular cavity. When cylindrical piston 1 moves downward, one-way valve 3 is opened, and the upper and lower ends of cylindrical piston 1 are connected, so cylindrical piston 1 can move downward smoothly).

[0044] In the above scheme, when the motor starts and drives the lifting rod upward, the lifting rod drives the connecting rod two upward, which in turn drives the cylindrical piston one to force the gas in the cylindrical cavity one into the annular cavity through the connecting pipe one. This, in turn, drives the annular piston and the drive ring upward. The drive ring no longer squeezes the sealing ring. As the cylindrical piston one continues to move upward, the gas in the cylindrical cavity one is continuously forced into the annular cavity, causing the gas pressure in the annular cavity to continuously increase until it reaches the pressure relief valve. The pressure relief valve opens to release pressure. At this time, the gas pressure in the annular cavity is in a constant state (the input gas volume and the output gas volume are approximately the same). The drive ring remains in the upward state pushed by the connecting rod one. When the lifting rod stops rising, the gas in the annular cavity... When the gas stops, the pressure relief valve is not yet closed (the pressure relief valve here is set to close with a 1-second delay; specifically, a hydraulic / pneumatic damper is added to the mechanical structure of the pressure relief valve to slow down the valve core reset speed and achieve a short delay). The gas in the annular cavity flows out from the air pipe. The air pressure at the lower end of the drive ring is less than the elastic force of the spring. Under the action of the spring, the drive ring moves downward to re-compress the sealing ring. This achieves the release of the compression of the sealing ring 29 by the drive ring 28 during the lifting rod's ascent. After the lifting rod's ascent is completed, the drive ring 28 resumes compression of the sealing ring 29. This ensures the sealing effect while preventing the sealing ring from being damaged by the friction of the lifting rod.

[0045] Furthermore, in order to release the pressure of the drive ring on the sealing ring during the descent of the lifting rod, the linkage component also includes a connecting rod 3 10, a guide rod 2 12, and a cylindrical piston 22. The fixed column 5 is provided with a cylindrical cavity 2 7 for installing the cylindrical piston 22 and a movable groove 2 11 that mates with the guide rod 2 12. One end of the guide rod 2 12 is connected to the lifting rod, and the other end is connected to the connecting rod 3 10. The end of the connecting rod 3 10 away from the guide rod 2 12 extends into the cylindrical cavity 2 7 and is fixedly connected to the cylindrical piston 22. The lower end of the cylindrical cavity 2 7 is connected to the annular cavity 33 through a connecting pipe 2 9. The two ends are connected, and a one-way valve 8 is provided on the connecting pipe 2 9. The one-way valve 8 is used to control the unidirectional flow of gas from the cylindrical cavity 2 7 to the annular cavity 33. A one-way valve 4 23 is provided on the cylindrical piston 22. The one-way valve 4 23 is used to control the unidirectional flow of gas in the cylindrical cavity 2 7 from the upper end to the lower end (that is, when the cylindrical piston 2 moves upward, the one-way valve 4 opens, the upper and lower ends of the cylindrical piston 2 are connected, and the cylindrical piston 2 can move upward smoothly; when the cylindrical piston 2 moves downward, the one-way valve 4 closes, and the cylindrical piston 2 forces the air in the cylindrical cavity 2 into the annular cavity). The rotation limit of the lifting rod is achieved by the cooperation of the guide rod 1 and the movable groove 1 and the guide rod 2 and the movable groove 2. During the descent of the lifting rod, the cylindrical piston moves downward, forcing the gas in the cylindrical cavity 2 into the annular cavity through the connecting pipe 2. The remaining actions are the same as the lifting rod's upward action, so they will not be described in detail.

[0046] The above solution achieves the release of the pressure of the drive ring 28 on the sealing ring 29 during the lifting and lowering process of the lifting rod. After the lifting rod has completed its lifting or lowering motion, the drive ring 28 resumes its pressure on the sealing ring 29. This ensures the sealing effect while preventing the sealing ring from being damaged by the friction of the lifting rod.

[0047] It should be noted that the inner diameter of the sealing ring should be equal to or slightly larger than the diameter of the lifting rod. When the drive ring stops compressing the sealing ring, the sealing ring and the lifting rod are in a transition or clearance fit. Therefore, the sealing ring will not rub against the lifting rod during the lifting process.

[0048] In order to ensure that the compression of the sealing ring by the drive ring is released before the lifting rod rises or falls, the lifting rod further includes a mating section 15, a lifting section 3, and a second spring 17. The lower end of the lifting section 3 is provided with a receiving hole that mates with the mating section 15. The second spring 17 is installed in the receiving hole, with one end of the second spring 17 fixedly connected to the bottom of the receiving hole and the other end fixedly connected to the mating section 15. A threaded hole is provided on the mating section 15. The lifting section 3 is provided with a mating hole that mates with the lead screw 20. The first guide rod 16 and the second guide rod 12 are both fixedly connected to the mating section 15.

[0049] In the above scheme, when the electric motor drives the lead screw to rotate, the mating section that engages with the lead screw thread moves upward first. Due to the static friction between the lifting section and the wall of the receiving hole, the mating section first compresses the second spring upward. At this time, the cylindrical piston pushes the gas in the cylindrical cavity into the annular cavity through the connecting pipe, thereby driving the annular piston and the drive ring to move upward. The drive ring no longer compresses the sealing ring until the elastic force of the second spring is greater than the static friction between the lifting section and the wall of the receiving hole. The lifting section moves upward under the action of the mating section. At this time, the lifting section and the receiving hole... Dynamic friction is formed between the hole walls (dynamic friction is less than static friction, and spring two will recover some of its deformation compared to before). Therefore, during the upward movement of the lifting section, spring two is compressed less than when the lifting section and the receiving hole are in a static friction state. This ensures that when the lifting rod needs to be raised or lowered later, spring two is compressed first when the lifting section and the receiving hole are in a static friction state, so that the pressure of the drive ring on the sealing ring is released before the lifting rod rises. Similarly, the principle is the same when the lifting rod descends as when it rises, so it will not be elaborated further.

[0050] It should be noted that the lifting rod is fitted with a telescopic rubber sleeve 4. One end of the telescopic rubber sleeve 4 is fixedly connected to the upper part of the lifting rod, and the other end is fixedly connected to the upper end of the fixed column 5. The telescopic rubber sleeve can initially protect the joint between the lifting rod and the fixed column.

[0051] The above description only illustrates the preferred embodiments of the present invention and should not be construed as limiting the scope of the claims. The present invention is not limited to the above embodiments, and variations in its specific structure are permitted. All modifications made within the scope of the independent claims of this invention are also within the scope of protection of this invention.
