Description

Technical Field

[0001] The utility model relates to a barrel plate leakage detection device, belonging to the technical field of wooden barrel production detection equipment. Background Art

[0002] As living standards improve, people are increasingly pursuing the quality of life. Therefore, people are consuming more and more wine, which is good for the body and can adjust the interest of life, which has led to the rapid development of the wine industry in China. Wine is a living organism that can "breathe". During the aging process of wine, it needs to be in contact with trace oxygen for slow aerobic maturation, so that the rough and astringent tannins become soft and smooth; but oxygen is the biggest enemy of wine. If there is too much oxygen, it will accelerate the aging of wine and make the wine as sour as vinegar. Therefore, the amount of oxygen contact with wine needs to be strictly controlled, and oak barrels can do this job. High-quality winemaking is inseparable from oak barrels. The wood density of oak is moderate, which allows appropriate trace air to enter the barrel to help the wine mature. Depending on the type of oak, the degree of oak barrel toasting, and the length of time the wine is aged in oak barrels, common aromas that oak can bring to red wine include vanilla, tobacco, coconut, caramel, cinnamon, cloves, cardamom, cedar, dark chocolate, smoked, toasted, toffee, coffee, almonds, hazelnuts, etc.; common aromas that oak can bring to white wine include butter, vanilla, sweet corn, cloves, cardamom, coconut, white chocolate, honey, etc. Therefore, oak barrels play an irreplaceable role in the brewing process.

[0003] The oak boards used to make oak barrels are processed from naturally grown oak logs. Since oak logs have texture and pores, it is easy to damage the texture and cause pore leakage if they are sawed. Therefore, the oak logs must be split along the texture and processed into boards. However, some of the boards processed in this way still have defects and leaks. Therefore, it is necessary to test whether the barrel boards are leaking. The traditional detection method is to assemble the oak barrel, add water to the barrel for pressure testing, observe the leakage outside the barrel, mark the leakage board, disassemble the barrel, replace it with a new oak board, and repeat the previous assembly process until there is no leakage in the barrel board.

[0004] However, an oak barrel has at least ten to dozens of oak boards, and each oak barrel board must go through planing, milling and other processing processes, and then go through multiple processes such as assembly, milling barrel cover grooves, baking, barrel closing, capping, and pressing hoops to complete the finished barrel. If all the boards have to be disassembled because of leakage, and then reassembled and processed barrel cover grooves and other processes, the disassembled leakage boards have been processed by milling, grooving, cutting, etc., and the material size has become smaller and there are grooves. The value of using them for other purposes is greatly reduced, and repeated operations are caused, resulting in low processing efficiency, waste of materials, and quality assurance. If the leaking barrel board can be found before assembly, there is no need for subsequent milling, grooving, cutting and other processing. The leaking board can be directly eliminated and used as a board for furniture, decoration, etc., which can greatly reduce waste, improve work efficiency, and ensure the quality of oak barrels.

[0005] Therefore, a barrel stave leak detection device is needed, which can detect leaking barrel staves before assembly. Utility Model Content

[0006] The utility model provides a barrel plate leakage detection device to solve the defects of low efficiency, waste of materials, and unguaranteed quality of existing barrel plate leakage detection.

[0007] The technical solution of the utility model to solve the above technical problems is as follows:

[0008] A barrel plate leak detection device comprises a frame, a detection platform is provided on the frame, a support structure is provided on the detection platform, at least one water inlet hole is provided on the detection platform, and the support structure is used to support the barrel plate to be detected; an upper clamping assembly is also provided on the frame, and the upper clamping assembly is used to clamp the barrel plate to be detected on the support structure, so that a closed space is formed between the support structure and the barrel plate to be detected.

[0009] The beneficial effects of the utility model are as follows: the utility model places the barrel board to be tested flat on the supporting structure of the testing platform, presses the barrel board to be tested by the upper pressing assembly to form a closed space between the barrel board to be tested and the supporting structure, injects water and applies pressure through the water inlet hole, and visually observes whether the barrel board to be tested is leaking, so as to achieve the purpose of detecting whether the barrel board is leaking, and realizes that leaking barrel boards can be found before assembly, and there is no need to conduct leakage detection after the barrel boards are assembled into oak barrels, thereby improving the efficiency of oak barrel processing, avoiding the waste of leaking oak board materials, and ensuring the quality of the assembled oak barrels.

[0010] On the basis of the above technical solution, the present invention can also make the following improvements:

[0011] Furthermore, the support structure includes at least one support frame, and the water inlet hole is arranged in the support frame.

[0012] The beneficial effect of adopting the above further technical solution is that the support frame can support the barrel board to be tested, the support frame has a simple structure, and it is more convenient to form a closed space between the barrel board to be tested, so as to facilitate testing.

[0013] Furthermore, when there are two or more support frames, gaps are provided between adjacent support frames, and notches are provided on the borders of adjacent support frames.

[0014] The beneficial effect of adopting the above further technical solution is that, when multiple support frames are provided, the support structure can support the barrel plate to be tested more stably, and the upper clamping assembly can clamp the barrel plate to be tested more tightly, and the test result is more accurate. The borders of the adjacent support frames are provided with gaps. If the number of water inlet holes does not correspond to the number of support frames, when water is injected from the water inlet holes, water can enter the support frame without water inlet holes through the gaps, which can reduce the number of water injection holes and the number of components that need to be adapted to the water inlet holes.

[0015] Furthermore, a sealing ring is provided on the detection platform.

[0016] The beneficial effect of adopting the above further technical solution is that the sealing effect between the barrel board to be detected and the support frame is further improved by the sealing ring. Since there is a gap between adjacent support frames, the size of the sealing ring can be set according to the length of the barrel board to be detected, and the gap between adjacent support frames can be used to install the sealing ring, so the detection of barrel boards to be detected with different lengths can be adapted by replacing sealing rings of different sizes.

[0017] Furthermore, the upper pressing assembly includes an upper pressing frame and an upper pressing driving mechanism, the upper pressing frame is hingedly arranged on the frame, and the upper pressing driving mechanism drives the upper pressing frame to move upward or downward.

[0018] The beneficial effect of adopting the above further technical solution is that the upper clamping frame is driven by the upper clamping drive mechanism to move upward to open or downward to clamp the barrel board to be tested, so that a closed space is formed between the barrel board to be tested and the support frame, thereby achieving the purpose of barrel board leakage detection.

[0019] Furthermore, the upper pressing frame includes an upper pressing frame and a plurality of upper pressing upright plates arranged in the upper pressing frame, and gaps are arranged between the upper pressing upright plates.

[0020] The beneficial effect of adopting the above-mentioned further technical solution is that uniform compression of the barrel plate to be tested is achieved through multiple upper compression vertical plates, the compression force is more uniform, the compression effect is better, and during the leak detection process, the gap between the upper compression vertical plates can be used to directly visually observe whether the barrel plate to be tested is leaking, which makes leakage detection of the barrel plate to be tested very convenient.

[0021] Furthermore, the upper clamping frame is hingedly arranged on the frame, the upper clamping drive mechanism includes an upper clamping cylinder, the cylinder body of the upper clamping cylinder is hingedly installed on the frame, and the piston rod end of the upper clamping cylinder is hingedly connected to the upper clamping frame.

[0022] The beneficial effect of adopting the above-mentioned further technical solution is that the upper clamping drive mechanism is an upper clamping cylinder, which drives the upper clamping frame to rotate, so that the movement of the upper clamping frame is smoother, and the cylinder body of the upper clamping cylinder is hinged on the frame. As the upper clamping frame rotates, the cylinder body of the upper clamping cylinder can swing, thereby preventing the cylinder body of the upper clamping cylinder from interfering with the rotation of the upper clamping frame.

[0023] Furthermore, the upper pressing drive mechanism includes at least two upper pressing cylinders, and the upper pressing frame is installed on the frame through the upper pressing cylinders.

[0024] The beneficial effect of adopting the above further technical solution is that the upper clamping frame is installed and driven to move upward or downward by the upper clamping cylinder.

[0025] Furthermore, the frame is also provided with a lateral pressing assembly, which is used to press the barrel plate to be tested from the side; and a baffle is provided on the side of the testing platform opposite to the lateral pressing assembly.

[0026] The beneficial effect of adopting the above-mentioned further technical scheme is that the lateral clamping assembly can realize the effect of laterally clamping the barrel board to be tested, and the baffle cooperates with the lateral clamping assembly to realize lateral clamping of the barrel board to be tested. When it is necessary to simultaneously test the leakage performance of multiple barrel boards, the lateral clamping assembly can tightly clamp the adjacent barrel boards, improve the sealing between the adjacent barrel boards, and prevent leakage and pressure release between the barrel boards when water and pressurization are added, thereby affecting the test effect.

[0027] Furthermore, the lateral pressing assembly includes a lateral pressing unit, and the lateral pressing unit includes a lateral pressing plate and a lateral pressing driving mechanism, and the lateral pressing driving mechanism drives the lateral pressing plate to laterally press the barrel plate to be inspected.

[0028] The beneficial effect of adopting the above-mentioned further technical solution is that the lateral clamping plate is driven by the lateral clamping drive mechanism to clamp the barrel plate to be tested, so that the contact between adjacent barrel plates is closer, and leakage and pressure release between the barrel plates when water and pressurization are prevented, which affects the test effect. By setting up multiple groups of lateral clamping units, the lateral clamping effect of the lateral clamping assembly on the barrel plate is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0040] Example 1

[0041] See also Figure 1-3 A barrel plate leak detection device comprises a frame 1, a detection platform 2 is provided on the frame 1, a support structure is provided on the detection platform 2, the detection platform 2 is provided with at least one water inlet hole 21 corresponding to the support structure, and the support structure is used to support the barrel plate 5 to be detected; an upper clamping assembly is also provided on the frame 1, and the upper clamping assembly is used to clamp the barrel plate 5 to be detected on the support structure, so that a closed space is formed between the support structure and the barrel plate 5 to be detected.

[0042] In this embodiment, the support structure includes a plurality of support frames 22 arranged side by side, and the water inlet holes 21 are correspondingly arranged in two of the support frames 22. The support frame 22 is used to support the barrel plate 5 to be tested. The support frame 22 has a simple structure and is more convenient to form a closed space with the barrel plate 5 to be tested (see Figure 8 ), which is convenient for detection. The support frame 22 is provided with a plurality of support structures to make the support of the barrel plate 5 to be detected more stable, and the upper clamping assembly can clamp the barrel plate 5 to be detected more tightly, and the detection result is more accurate.

[0043] When there are two or more support frames 22, gaps are provided between adjacent support frames 22, and gaps 23 are provided on the frames of adjacent support frames 22. The frames of adjacent support frames 22 are provided with gaps 23. If the number of water inlet holes 21 does not correspond to the number of support frames 22, when water is injected from the water inlet holes 21, water can enter the support frame 22 without the water inlet holes 21 through the gaps 23, which can reduce the number of water injection holes and the number of components that need to be adapted to the water inlet holes 21. In this embodiment, two water inlet holes 21 are provided, and the support frame 22 without the water inlet holes 21 is injected with water through the gaps 23 on the frames.

[0044] The detection platform 2 is provided with a sealing ring 24, and the support structure is arranged inside the sealing ring 24. The sealing ring 24 is arranged around the bottom of the barrel board 5 to be detected, and the sealing ring 24 further improves the sealing effect between the barrel board 5 to be detected and the support frame 22. Since there is a gap between adjacent support frames 22, the size of the sealing ring 24 can be set according to the length of the barrel board 5 to be detected, and the gap between adjacent support frames 22 can be used to install the sealing ring 24. Therefore, the detection of barrel boards 5 to be detected of different lengths can be adapted by replacing sealing rings 24 of different sizes. Fig. 9 When the length of the barrel board 5 to be detected is less than the overall length of the supporting structure, that is, the length of the barrel board 5 to be detected is less than the total length of multiple support frames 22, replace the sealing ring 24 so that the sealing ring 24 is adapted to the length of the barrel board 5 to be detected, and the sealing ring 24 can be installed in the gap of the support frame 22.

[0045] The upper clamping assembly includes an upper clamping frame 3 and an upper clamping driving mechanism, wherein the upper clamping frame 3 is hingedly arranged on the frame 1, and the upper clamping driving mechanism drives the upper clamping frame 3 to rotate around a hinge point. The upper clamping driving mechanism drives the upper clamping frame 3 to rotate around a hinge point, thereby realizing that the upper clamping frame 3 moves upward to open or moves downward to clamp the barrel board 5 to be inspected, so that a closed space is formed between the barrel board 5 to be inspected and the support frame 22, thereby realizing the purpose of barrel board leakage detection.

[0046] The upper pressing frame 3 includes an upper pressing frame 31 and a plurality of upper pressing upright plates 32 arranged in the upper pressing frame 31. Gaps are provided between the upper pressing upright plates 32. The barrel plate 5 to be inspected is evenly pressed by the plurality of upper pressing upright plates 32. The pressing force is more uniform and the pressing effect is better. Figure 5-8 During the leak detection process, the gap between the upper clamping plates 32 can be used to directly visually observe whether the barrel board 5 to be detected is leaking. The leakage detection of the barrel board 5 to be detected is very convenient. Furthermore, the upper clamping plates 32 are set corresponding to the gap between the support frames 22. The upper clamping plates 32 are set on the gap between the support frames 22. When the upper clamping plates 32 press the barrel board 5 to be detected downward, the barrel board 5 to be detected can be better in close contact with the frame of the support frame 22, thereby improving the sealing effect.

[0047] The upper clamping drive mechanism includes an upper clamping cylinder 33, the cylinder body of the upper clamping cylinder 33 is hingedly mounted on the frame 1, the piston rod end of the upper clamping cylinder 33 is hingedly connected to the upper clamping frame 31, in the present embodiment, two upper clamping cylinders 33 are symmetrically provided, and the two upper clamping cylinders 33 are respectively mounted at the two ends of the frame 1, the upper clamping drive mechanism is the upper clamping cylinder 33, the upper clamping cylinder 33 can adopt an oil cylinder, and the upper clamping frame 3 is driven to rotate by the oil cylinder, so that the movement of the upper clamping frame 3 is more stable, and the cylinder body of the upper clamping cylinder 33 is hinged on the frame 1, and the cylinder body of the upper clamping cylinder 33 can swing with the rotation of the upper clamping frame 3, so as to avoid the cylinder body of the upper clamping cylinder 33 interfering with the rotation of the upper clamping frame 3.

[0048] The frame 1 is also provided with a lateral pressing assembly, which is used to press the barrel board 5 to be tested from the side; the detection platform 2 is provided with a baffle 25 on one side of the lateral pressing assembly. The lateral pressing assembly achieves the effect of pressing the barrel board 5 to be tested from the side, and the baffle 25 cooperates with the lateral pressing assembly to achieve the lateral pressing of the barrel board 5 to be tested. When it is necessary to test the leakage performance of multiple barrel boards at the same time, the lateral pressing assembly can make the adjacent barrel boards tightly pressed, improve the sealing between the adjacent barrel boards, and prevent leakage and pressure release between the barrel boards when adding water and pressurizing, which affects the test effect, thereby detecting the leakage of the gap between the barrel boards.

[0049] The lateral pressing assembly includes a lateral pressing unit, which includes a lateral pressing plate 41 and a lateral pressing driving mechanism, and the lateral pressing driving mechanism drives the lateral pressing plate 41 to laterally press the barrel plate 5 to be detected, and the lateral pressing driving mechanism is a lateral pressing cylinder 42, and the piston rod end of the lateral pressing cylinder 42 is connected to the lateral pressing plate 41. The lateral pressing plate 41 is driven by the lateral pressing cylinder 42 to press the barrel plate 5 to be detected, which has a simple structure and is easy to operate, so that the contact between adjacent barrel plates is closer, and by setting multiple groups of lateral pressing units, the lateral pressing effect of the lateral pressing assembly on the barrel plate is improved.

[0050] See also Figure 4-7 Taking the simultaneous detection of three barrel staves 5 to be detected as an example, the barrel stave leakage detection method using the barrel stave leakage detection device of this embodiment includes the following steps:

[0051] Step 1, select the size of the sealing ring 24 according to the length of the barrel board 5 to be detected, install the sealing ring 24, place the barrel boards 5 to be detected side by side on the support frame 22, so that the sealing ring 24 is located around the bottom of the barrel board 5 to be detected, and place a sealing strip that matches the length of the barrel board 5 to be detected in the gap between adjacent barrel boards 5 to be detected to improve the sealing between adjacent barrel boards 5 to be detected;

[0052] Step 2: Start the lateral clamping cylinder 42. The piston rod of the lateral clamping cylinder 42 extends to drive the lateral clamping plate 41 to move toward the barrel board 5 to be detected, and cooperate with the baffle 25 to align the three barrel boards 5 to be detected from the side. At this time, do not pressurize to prevent the barrel board 5 to be detected from arching due to the pressurization.

[0053] Step 3, start the upper pressing cylinder 33, the piston rod of the upper pressing cylinder 33 contracts, driving the upper pressing frame 3 to rotate around the hinge point with the frame 1, and the upper pressing frame 3 presses the barrel board 5 to be detected downward. After the upper pressing frame 3 presses the barrel board 5 to be detected, no pressure is applied first, and the piston rod of the lateral pressing cylinder 42 is further extended until the lateral pressing cylinder 42 presses the barrel board 5 to be detected from the side, and then the piston rod of the upper pressing cylinder 33 is further contracted to press the upper pressing frame 3 to be detected from the top of the barrel board 5;

[0054] Step 4: After the upper pressing frame 3 presses the barrel board 5 to be tested from top to bottom, water is passed through the water inlet hole 21 for pressurization, and the worker visually checks whether the barrel board 5 to be tested is leaking from the gap between the upper pressing vertical plates 32 of the upper pressing frame 3, and the worker marks the leaking point of the barrel board 5 to be tested;

[0055] Step 5. After the test is completed, the lateral clamping cylinder 42 drives the lateral clamping plate 41 away from the barrel board that has been tested, and the upper clamping cylinder 33 drives the upper clamping frame 3 away from the barrel board that has been tested. The barrel boards that have been tested are taken out and classified and placed (the barrel boards with leakage are stored separately from the barrel boards that have passed the test), and then the above steps are repeated to perform leakage test on the next batch of barrel boards 5 to be tested.

[0056] The utility model presses and compacts the barrel board 5 to be detected from the side and top of the barrel board 5 to form a closed space between the barrel board to be detected and the supporting structure, and then simulates the water pressure state of the oak barrel after being filled with wine by injecting water into the closed space to pressurize it. The purpose of detecting whether the barrel board is leaking can be achieved by visual inspection, and the leaking barrel board can be found before assembling the oak barrel, avoiding the disadvantages caused by the barrel board leakage found after assembly, improving the efficiency of oak barrel processing, avoiding the waste of leaking oak board materials, and ensuring the quality of the assembled oak barrel.
