Description

Technical Field

[0001] This invention belongs to the technical field of wine brewing testing equipment, and more specifically, it is a testing instrument for grape spirits brewing. Background Technology

[0002] As a high-alcohol distilled spirit, grape spirits undergo several crucial stages in their production, including fermentation, distillation, and aging. The alcohol content, acidity, sugar content, and microbial content of the spirit directly determine the quality and safety of the final product. Currently, industry testing of grape spirit production processes largely relies on manual sampling using handheld samplers inserted into the fermentation tanks. This method is not only labor-intensive but also lacks the ability to automatically control sampling depth, resulting in samples from only a single location. It fails to reflect the differences in indicators at different depths and in different areas within the tank, easily leading to biased test results and affecting the accuracy of adjustments to the brewing process.

[0003] Furthermore, existing testing equipment is mostly a standalone unit, with alcohol and acidity meters scattered across the site, occupying a large space. There is a lack of coordination between these devices, requiring manual transport of samples to different devices after sampling, a cumbersome and inefficient process. This transport process also increases the risk of sample contamination or leakage, affecting testing accuracy. Moreover, this decentralized equipment makes maintenance inconvenient, carries a high risk of contamination, and allows alcohol samples to leak or condensate during testing. Existing equipment lacks a dedicated collection structure, and leaked liquid can corrode equipment components or contaminate the operating environment. Additionally, the testing modules are mostly fixed, making disassembly and cleaning nearly impossible. In practice, brewing workshops are densely packed with equipment and pipelines. Traditional testing equipment lacks a flexible operating platform, and there is insufficient space for sample processing and equipment debugging after sampling. It is very troublesome to move the tables and other items used to place the testing tools into the workshop as well. The aforementioned problems result in low testing efficiency and cumbersome operation in the winemaking process, making it difficult to meet the needs of real-time monitoring and precise control in modern winemaking production. Therefore, there is an urgent need for an integrated, high-precision, and easy-to-operate testing device. Summary of the Invention

[0004] In view of the current state of the technology mentioned in the background section, and in order to overcome the corresponding defects in the existing technology, the present invention specifically discloses a testing instrument for grape spirits brewing, which can better solve the problems mentioned in the background section.

[0005] To overcome the deficiencies of the existing technology, those skilled in the art provide the following technical solutions: A testing instrument for grape spirits production includes a cabinet, a modular mounting cavity, and several testing modules. The cabinet is a vertical hollow structure, with its interior divided vertically into several independent modular mounting cavities for installing the testing modules. Each modular mounting cavity has a guide rail and an elastic limiting buckle on its inner wall. The testing modules are embedded into the modular mounting cavities via the guide rail at the bottom of their drawers and are locked in place by the elastic limiting buckles. A folding operating platform is provided on the outside of the cabinet. The folding operating platform includes two hinged operating plates. One side of the first operating plate is hinged to the outer wall of the cabinet. The non-hinged side of the second operating plate is in contact with the upper surface of the storage platform when the folding operating platform is folded and stored on a storage table on the side wall of the cabinet. A locking pin is inserted into the storage table and is vertically elastically telescopically mounted in the storage table. When the folding operating platform is unfolded, a support rod at the bottom of the second operating plate falls to the ground, and at this time, a hole at the bottom of the first operating plate is inserted by the locking pin. It also includes a sampling mechanism that can adjust the sampling position. The sampler of the sampling mechanism can reach different depths of the brewing tank, and after collecting samples from the surrounding area with the depth position as the center, it is transferred to the module installation cavity.

[0006] Furthermore, the sampling mechanism also includes a lifting adjustment component, a horizontal telescopic arm, and an angle deflection mechanism; the lifting adjustment component is vertically fixed to one side of the cabinet, and includes a lead screw and a drive motor as the driving force to drive the horizontal telescopic arm to rise and fall in the vertical direction; the horizontal telescopic arm adopts a multi-level nested structure, and the telescopic end is connected to the angle deflection mechanism; the sampler can be detachably connected to the angle deflection mechanism to realize multi-position and multi-angle sample collection.

[0007] Furthermore, the lead screw is vertically and rotatably installed on the side of the cabinet facing away from the folding operating platform. A slide is threaded onto the lead screw, and one side of the slide slides in contact with the side wall of the cabinet to achieve vertical movement of the slide. A rotary motor is installed on the slide, and the main shaft of the rotary motor is fixedly connected to the non-telescopic end of the horizontal telescopic arm to drive the horizontal telescopic arm to rotate in the vertical plane.

[0008] Furthermore, the angle deflection mechanism includes a motor base, a micro motor, a cantilever tube, a mounting base, a connecting rod, and a drive assembly. The motor base is fixed to the telescopic end of the horizontal telescopic arm. The micro motor is mounted on the motor base, and its main shaft rotates downward through the motor base and is fixed to the cantilever tube. The mounting base is fixed to the bottom end of the cantilever tube, and the drive assembly is provided on the mounting base. The drive assembly drives the connecting rod used to mount the sampler to swing left and right, so that the sampler can extend into the brewing tank and the module mounting cavity. Furthermore, the drive assembly includes a hydraulic rod, a drive rack, and a driven gear. The driven gear is rotatably mounted on the mounting base. The connecting rod is vertically fixed to the gear shaft of the driven gear near its top end. The drive rack is vertically slidably mounted on one side of the mounting base and meshes with the driven gear. The top end of the drive rack is fixed to the telescopic rod so that during extension and retraction, the drive rack slides vertically, causing the connecting rod to swing left and right.

[0009] Furthermore, the mounting base has an L-shaped structure, the driven gear is rotatably mounted in the vertical plate of the mounting block, the bottom end of the cantilever tube is fixed to the horizontal plate of the mounting block, the driving gear slides vertically through the horizontal plate, and the hydraulic rod is mounted on one side of the cantilever tube.

[0010] Furthermore, a push plate is provided above the connecting rod. The push plate is horizontally set and vertically slidably installed on the side wall of the cantilever tube. It can be lifted by the top of the connecting rod in a vertical state to stop at the corresponding height on the side of the cantilever tube.

[0011] Furthermore, the wall of the cantilever tube is provided with a vertical groove, and at the opening of the vertical groove, several scale lines are evenly spaced along its length to characterize the relative displacement adjustment of the sampler in the depth direction inside the brewing tank.

[0012] Furthermore, each module mounting cavity is equipped with a flow guide groove and a liquid collection box at the bottom. The flow guide groove is tilted forward at an angle of 5°-10°. The liquid collection box is detachably connected to the module mounting cavity via a buckle and is used to collect samples or condensate that leak during the testing process.

[0013] Furthermore, a handle is fixed to the side of the second operating panel, and the first operating panel is hinged to the outside of the cabinet side wall via a hinge post; a pin cap is fixed to the bottom of the locking pin, and the top of the pin cap is connected to the bottom of the storage table by a tension spring. Under normal conditions, the tension spring restricts the locking pin to a position that penetrates the top surface of the storage table so that it can be inserted into the corresponding parts of the two operating panels.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: through the coordinated cooperation of the lifting adjustment component, the horizontal telescopic arm and the angle deflection mechanism, the sampler can automatically and flexibly reach any position inside the brewing tank, and take the point on the axial direction of the depth as the center to perform multi-point sampling around different depths, effectively avoiding the limitations of single-position sampling and ensuring that the sample can comprehensively reflect the index of the wine in the tank; at the same time, the scale line on the cantilever tube can intuitively display the change of sampling depth, that is, it is easy to grasp the change of the sampler's moving depth inside the brewing tank. The cabinet is divided into multiple independent modular installation cavities, which can centrally install various testing modules without the need for scattered placement, thus saving a significant amount of workshop space. Furthermore, each testing module can be quickly assembled and disassembled through guide rails and elastic limit buckles. During maintenance, the module can be pulled out simply by pressing the buckle, making the operation convenient and reducing maintenance costs. An additional integrated folding operating platform is included, which can be flexibly unfolded or folded up as needed. When unfolded, it forms a stable operating surface, providing ample space for sample processing and equipment debugging. When folded up, it fits snugly against the side wall of the cabinet, without occupying additional space. The sampling process of this invention is driven entirely by a mechanical structure, eliminating the need for manual handling of the sampler, significantly reducing the labor intensity of operators. After sampling, the sample can be transferred to the detection module with the assistance of an angle deflection mechanism, simplifying the operation process and improving detection efficiency. In addition, the bottom of the module mounting cavity of the present invention is provided with a guide groove and a liquid collection box, which can effectively collect the samples or condensate that leak during the testing process, avoid corrosion of equipment parts or pollution of the environment, and extend the service life of the equipment. Other functions and features of the present invention will be described in detail in the following embodiments to provide a full understanding of the concept of the present invention and to enable its practical application in production.

Detailed Implementation

[0017] Based on the accompanying drawings and the following description, the technical solutions in the embodiments of the present invention can be clearly and completely described. However, it should be understood that the embodiments mentioned herein are merely one or several specific methods of the present invention, and not all implementation structures or method steps.

[0018] like Figure 1 As shown, this invention proposes a testing instrument for grape spirits brewing in this embodiment. Its structural design includes a cabinet 1, a modular mounting cavity 2, and several testing modules. These testing modules include real-time detection of alcohol content, acidity, sugar content, and microbial indicators of the wine during the brewing process. When assembling the whole, the cabinet 1 can be made of 304 stainless steel. The interior is divided into multiple layers vertically by horizontal stainless steel partitions 101 (not shown in the figure), for example, divided into 4 independent modular mounting cavities 2. The height of each cavity and the spacing between the layers are adaptively designed according to the equipment size of the selected testing modules. The partitions 101 are fixed to the side wall of the cabinet 1 by bolts or integrally formed to ensure the stability of the cavity structure. In this embodiment, as Figure 9 As shown, guide rails 3 are symmetrically welded to the left and right inner walls of the mounting cavity 2 of each module. The rails are rectangular columnar structures, and their width is adapted to the slider at the bottom of the pull plate 33 of the detection module. The elastic limiting buckle 4 in this embodiment can be installed using existing elastic snap-fit ​​structures. For example, it can be made of polyurethane and fixed to the corresponding cavity sidewall with screws, or as... Figure 9As shown, a pair of elastic protrusions 35, each mounted by a cylindrical spring, extend toward the ear plate 34 fixed to the inner surface of the aforementioned draw plate 33. When the detection module is fully pushed into the cavity, the elastic protrusions 35 engage with the horizontally positioned positioning holes on the ear plate 34 to achieve locking and fixation. In use, the two elastic protrusions 35 can be pried apart to release the lock on the ear plate 34, thus releasing the ear plate 34. This makes it convenient to remove the detection module for maintenance or other detection operations. In this embodiment, as Figures 1-3 As shown, a folding operating platform is provided on the outside of the cabinet 1. The folding operating platform includes two operating plates that are hinged to each other. One side of the first operating plate 8 is hinged to the outer wall of the cabinet 1. During operation, once the folding operating platform is folded and stored on a storage platform 7 on the side wall of the cabinet 1, the non-hinged side of the second operating plate 9 will come into contact with the upper surface of the storage platform 7 and be inserted by a locking pin 11 that is vertically and elastically telescopically installed in the storage platform 7, thereby achieving the fixed storage and installation of the folding operating platform. When the folding operating platform is unfolded, a support rod 10 at the bottom of the second operating plate 9 will automatically fall to the ground to provide support. At this time, a hole at the bottom of the first operating plate 8 is precisely inserted by the locking pin 11, thereby fixing the unfolded posture of the folding operating platform. In the specific manufacturing process, both the first operating plate 8 and the second operating plate 9 of this folding operating platform are made of non-slip aluminum alloy plates. One side of the first operating plate 8 can be hinged to the lower left side of the cabinet 1 through a stainless steel hinge post 32, ensuring that the operating plate can be flipped smoothly. The storage platform 7 can be a stainless steel block welded to the side wall of the cabinet 1, for the folded operating platform to be placed in a close fit. As a specific embodiment, the detailed implementation structure of this sampling mechanism is as follows: Figure 1 As shown, the lead screw 15 adopts a trapezoidal thread structure, and its two ends are rotatably mounted on the stainless steel bracket on the right side of the cabinet 1 through deep groove ball bearings. The bracket is welded and fixed to the cabinet 1. The drive motor 16 is a stepper motor, which is connected to the top of the lead screw 15 through a coupling. The housing of the drive motor 16 is fixed to the top side of the cabinet 1 by bolts through the motor seat 20. In addition, the slide 17 is a cuboid structure with a threaded hole on the inner side that matches the lead screw 15. The outer side is slidably engaged with the vertical guide rail on the right side of the cabinet 1 through a slider, ensuring that the slide 17 rises and falls smoothly in the vertical direction. A rotary motor (not shown in the figure) is fixed on the slide 17. As the slide 17 moves vertically, the main shaft of the rotary motor is rigidly connected to the fixed end of the horizontal telescopic arm 18 through an existing structure such as a flange. In this way, the horizontal telescopic arm 18 can be driven to rotate in the vertical plane to realize the switching of sampling direction. For example, the sampler 23 can enter the brewing tank, or rotate in the opposite direction to enter the module installation cavity 2 mentioned above. In more detail, such as Figure 1As shown, in this embodiment, the horizontal telescopic arm 18 and the angle deflection mechanism utilize a three-stage nested aluminum alloy tube. Its telescopic end is fixed to the motor base 20 via bolts or other connecting elements. The motor base 20 of the angle deflection mechanism can be a square stainless steel block. The micro motor 19 is fixed to the upper part of the motor base 20, and the main shaft is fixed to the cantilever tube 21 via a key connection to ensure synchronous rotation. Furthermore, as... Figure 7 This mounting block is an L-shaped stainless steel component, consisting of a horizontal plate 2801 and a vertical plate 2802, forming an angle steel structure. The horizontal plate 2801 is fixed to the bottom end of the cantilever tube 21 by bolts, etc. A bearing seat is provided inside the vertical plate 2802, and the gear shaft 27 of the driven gear 26 is mounted in the bearing seat via a bearing. Figures 4-6 The driving rack 25 vertically passes through the guide hole of the horizontal plate 2801 of the mounting base 28 and meshes with the driven gear 26. The hydraulic rod 24 is a small and micro hydraulic push rod. Its cylinder body can be fixed to the side wall of the cantilever tube 21 by clamping. The top of the telescopic rod is welded and fixed to the driving rack 25 to realize the vertical movement of the driving rack 25. In this embodiment, the connecting rod 22 is a stainless steel round rod, and its bottom end is detachably connected to the sampler 23 via a thread. The sampler 23 is a component used in the prior art for targeted sampling, such as a common needle-type sampling head, with a sampling hole at its end. Figures 4-6 As shown, in actual manufacturing, it is advisable to have rounded corners at the contact point between the top of the connecting rod 22 and the push plate 29. The push plate 29 is a rectangular stainless steel plate, such as... Figure 8 The sampler 23 can slide and engage with the vertical groove on the side wall of the cantilever tube 21 via its slider 2901. The slider 2901 can be a T-shaped slider. When the connecting rod 22 is vertical, the push plate 29 is lifted to the corresponding height, which can visually indicate the initial position of the sampler 23. The edge of the vertical groove 30 provided on the cantilever tube 21 has a series of scale lines 31. These zero scale lines 31 reflect the displacement of the sampler 23. In practice, the sampler 23 first penetrates to the deepest central part to collect a sample, which is then sent back to the corresponding module mounting cavity 2 for detection by the corresponding detection module. It then re-enters the previous depth and, via the drive gear, swings the connecting rod 22 to a certain tilt angle to collect a sample from the central position inside the brewing tank. Due to the swinging of the connecting rod 22, the sampler 23 not only deviates from the center of the brewing tank but also moves upwards by a displacement. This displacement can be indirectly represented by the displacement of the push plate 29. This is because when the connecting rod 22 rotates around the center of the gear shaft 27 of the driven gear 26, the vertical displacement of the ends of the connecting rods 22 on both sides of the gear shaft 27 is proportional to the vertical displacement of the connecting rods 22 on both sides of the gear shaft 27. This is because when the connecting rod 22 rotates around the gear shaft 27, the vertical displacement relative to the original position of the connecting rod 22, or relative to the connecting rod 22 in the previous position, is... Figures 10-11The two triangles formed are opposite each other and belong to similar triangles with a certain similarity ratio. Therefore, based on the similarity ratio, the vertical displacement adjustment of sampler 23 in the brewing tank can be indirectly obtained. The calculation principle of the similarity ratio of similar triangles is existing technology and will not be elaborated here. It can be easily obtained by combining the similarity ratio and trigonometric function relationship. Those skilled in the art can consult and calculate it themselves. In addition, this ratio value can also be directly plotted on the graph of the motion trajectory of link 22. The above structural design also has the advantage that the sampler 23 is far from the gear shaft 27, while the other end of the connecting rod 22 is close to the gear shaft 27. Therefore, a large vertical height adjustment of the sampler 23 can be achieved by a very small vertical displacement of the push plate 29. That is, by adjusting and controlling the installation height of the push plate 29 within a very small range, the height change of the sampler 23 in the brewing tank can be controlled. Combined with the angle of rotation of the connecting rod 22 with the gear shaft 27, the sampling position can be determined. Combined with the drive of the lead screw 15, sampling can be achieved at different positions around each depth in multiple depth directions of the brewing tank. In this embodiment, the bottom of each module mounting cavity 2 is provided with an inclined guide groove 5. Specifically, it can be made of stainless steel in one piece, with an inclination angle of 8°. A liquid guide hole (not shown in the figure) can also be provided at the lowest point of the groove bottom. The liquid collection box 6 is made of plastic, with a liquid inlet at the top corresponding to the liquid guide hole, or it can be directly connected to the outlet of the aforementioned guide groove 5. In specific manufacturing, such as... Figure 1 The partition 101 is secured to the liquid collection box 6 by the buckles on both sides of its bottom, allowing it to be pulled out and cleaned periodically to prevent leakage from contaminating the equipment. In the above embodiments, the detection modules involved include an alcohol content detection module, an acidity detection module, etc. The bottom of the draw plate 33 of each module is provided with a sliding structure that is adapted to the guide rail 3. When pushed into the cavity, the slider slides along the guide rail 3. After it is in place, the elastic limit buckle 4 automatically locks in place to ensure that the module is stable and has no displacement deviation during the detection process. For the design of the folding operating platform, a handle 14 can be installed on the side of the second operating panel 9. The handle 14 is a U-shaped stainless steel piece, welded to the outer edge of the panel, making it convenient for the operator to pull and unfold. The aforementioned locking pin 11 is a stainless steel round rod, similar in size and shape to a bolt. For example, the diameter of the stainless steel round rod is 8mm, the diameter of the pin cap 13 is 15mm, and the tension spring 12 is a stainless steel tension spring. Under normal conditions, the tension spring 12 is in a stretched state. Pulling the locking pin 11 upwards is preferable, so that its top extends at least 10mm beyond the top surface of the storage platform 7. When the folding platform is folded, the second operating plate 9 fits against the storage table 7, and the locking pin 11 is inserted into the locking hole of the second operating plate 9 to achieve fixation. When unfolding, the operator pulls down the pin cap 13, the tension spring 12 is stretched, the locking pin 11 moves down to release the corresponding lock, and the second operating plate 9 is pulled to unfold. When the two operating plates are horizontal, the pin cap 13 is released, the tension spring 12 returns to its original position, the locking pin 11 is inserted into the insertion hole at the bottom of the first operating plate 8, and at the same time the support rod 10 at the bottom of the second operating plate 9 falls to the ground to form a stable operating surface. The support rod 10 can also be a telescopic structure, and its length can be adjusted according to the flatness of the ground. During the sampling operation, the drive motor 16 is started, and the lead screw 15 drives the slide 17 to rise and fall, adjusting the ideal height of the horizontal telescopic arm 18. The angle of the horizontal telescopic arm 18 is adjusted to be horizontal by rotating the motor, while the connecting rod 22 is initially in a vertical position. The horizontal telescopic arm 18 is extended, and the sampler 23 is located in the center above the opening of the brewing tank. Then, the lead screw 15 lowers the slide 17, sending the sampler 23 into the corresponding depth inside the brewing tank. Then, the hydraulic rod 24 is started, and the telescopic rod extends and retracts, causing the active rack 25 to slide. The driven gear 26 rotates, driving the connecting rod 22 to swing left and right. The connecting rod 22 tilts, and the push plate 29 begins to slide down. The depth of the sampler 23 inside the brewing tank can be indirectly determined by observing the scale line 31 of the cantilever tube 21 where the push plate 29 is located. After sampling is completed, the sampler 23 is removed from the brewing tank by reversing the operation.

[0019] Detection operation: Move the sampler 23 to the front of the corresponding detection module, adjust the angle of the sampler 23 by the angle deflection mechanism, and inject or send the sample into the detection module for detection; during the detection process, any leaked sample or condensate flows into the liquid collection box 6 along the guide channel 5, which can be cleaned periodically. Storage Operation: After the test is completed, close all test modules and check whether each test module is accurately pushed into its corresponding cavity and locked. Pull out the locking pin 11, fold the operation plate so that its side is against the storage platform 7, release the locking pin 11, and insert the locking pin 11 into the socket of the second operation plate 9 to complete the storage.

[0020] The above is just one method of use. The detector described in this invention can be used in a flexible manner as needed and is not limited to the above methods.

[0021] This invention is not limited to the field covered by this embodiment. Some well-known structures or principles have not been further described. However, those skilled in the art can theoretically know all the well-known technologies in this field prior to the application date or priority date, and can fully master all the prior art in this field. They also have the means and ability to apply these prior art in practical design. Under the technical guidance provided in this application, those skilled in the art can more comprehensively improve and implement this invention by combining their own capabilities. Furthermore, it should be noted that although the text and graphics of the above embodiments have shown specific implementation scenarios of the invention, those skilled in the art can make various obvious extensions and expansions to these embodiments without departing from the design concept of the invention, forming different embodiments. However, this does not affect the fact that the scope of protection of the invention is covered and embodied by the technical features of this claim and equivalent technical features.
