Description

Technical Field

[0001] This utility model relates to a monitoring device, specifically a liquid level monitoring and alarm device for wine jars. Background Technology

[0002] In the production of baijiu (Chinese liquor), distillation is a crucial step in extracting its aroma and flavor. During distillation, the receiving jar is used to collect the baijiu flowing from the distillation tower, and changes in its liquid level directly reflect the efficiency and stability of the distillation process. Therefore, real-time monitoring and alarm functions for the liquid level in the receiving jar are essential to ensuring the smooth progress of the distillation process and product quality.

[0003] Traditional liquid level monitoring methods mainly rely on regular manual inspections, which are not only inefficient but also susceptible to human error and safety hazards. With the development of automation technology, some automated liquid level monitoring devices have begun to be applied in industrial production; however, these devices are mostly complex in structure, expensive, and require professional personnel for maintenance and operation. Furthermore, due to the unique characteristics of the liquor distillation process, such as high temperature, high pressure, and volatility, designing and implementing liquid level monitoring devices suitable for this process is even more challenging.

[0004] To address the aforementioned issues, the float-based monitoring method was developed. This method involves placing a float above the wine jar and using the principle of buoyancy to monitor changes in the liquid level. When the liquid level rises, the float rises accordingly; when the liquid level falls, the float falls accordingly. By measuring the position of the float, the liquid level in the wine jar can be indirectly determined. This method is simple in structure, low in cost, and easy to maintain. However, in practice, some problems have been found with the single-float scheme: First, it suffers from insufficient accuracy, especially when the liquid level changes rapidly or fluctuates significantly, in which case the float may not accurately reflect the true liquid level. Second, the reliability of the single-float scheme cannot be fully guaranteed. Since there is only one float and sensor used in this scheme, if it fails, there is no backup, often leading to the liquid level exceeding the limit. Utility Model Content

[0005] The purpose of this invention is to provide a liquid level monitoring and alarm device for wine jars to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A liquid level monitoring and alarm device for a wine jar includes an alarm and a jar mouth support, the jar mouth support having a wine inlet; vertically distributed liquid level measuring cylinders are fixed below the jar mouth support, the top of the liquid level measuring cylinders having an exhaust hole, the liquid level measuring cylinders dividing the internal space of the wine jar into an external wine receiving space and an internal wine receiving space; a liquid level monitoring mechanism is placed inside the liquid level measuring cylinders, and the liquid level monitoring mechanism transmits information to the alarm.

[0008] In a further embodiment, the liquid level monitoring mechanism includes a vertical guide rod fixed below the jar mouth support. Multiple floats are slidably sleeved on the outer wall of the guide rod. A sensor installed on the outer wall of the guide rod is provided between two adjacent floats. A wire is connected between the sensor and the alarm. Part of the wire is hidden inside the guide rod, and the other part extends out of the jar mouth support and is connected to the alarm.

[0009] In a further embodiment, a plurality of limiting protrusions are evenly distributed on the guide rod, and the float is located between two adjacent limiting protrusions, wherein the number of floats is preferably two.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model utilizes a liquid level measuring cylinder to divide the liquid surface into two parts. When the liquid surface outside the liquid level measuring cylinder experiences large fluctuations, it will not affect the liquid surface inside the liquid level measuring cylinder, thereby reducing the fluctuation amplitude of the float. This effectively avoids the problem of large liquid surface fluctuations, enabling the liquid level monitoring mechanism to accurately reflect the true liquid level and improve monitoring accuracy.

[0012] 2. In this utility model, a multi-float scheme is adopted. While retaining the advantages of simple structure, low cost and easy maintenance of the float scheme, it can provide an adjustable alarm threshold function, allowing users to set high and low liquid level alarm points according to actual needs, increasing the applicability and flexibility of the device. On the other hand, it also avoids the problem of no backup scheme due to damage of the single float scheme. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-2 As shown, this embodiment discloses a liquid level monitoring and alarm device for a wine jar, including an alarm 1 and a jar mouth support 2. A vertical liquid level measuring cylinder 3 is fixed below the jar mouth support 2. The liquid level measuring cylinder 3 has an exhaust hole 4 at its top. A liquid level monitoring mechanism is placed inside the liquid level measuring cylinder 3, and information can be transmitted between the liquid level monitoring mechanism and the alarm 1. A wine inlet 5 is provided on the jar mouth support 2. The liquid level monitoring mechanism includes a vertical guide rod 6, which is also fixed below the jar mouth support 2. Several limiting protrusions 7 are evenly distributed on the guide rod 6. A float ball 8 slides between every two limiting protrusions 7 on the guide rod 6. A sensor 9 is provided inside the guide rod 6 between every two limiting protrusions 7. Each sensor 9 is connected to the alarm 1 by a wire. Part of the wire is hidden inside the guide rod 6, and the other part extends out of the jar mouth and connects to the alarm 1. The number of float balls 8 is preferably two, depending on the usage requirements. Both are made of lightweight materials, such as plastic or lightweight metal, with a density less than that of liquor, so they can float on the liquid surface.

[0018] By dividing the liquid surface into two parts using the liquid level measuring cylinder 3, when the liquid surface outside the liquid level measuring cylinder 3 experiences large fluctuations, it will not affect the liquid surface inside the liquid level measuring cylinder 3, thereby reducing the fluctuation amplitude of the float 8. This can effectively avoid the problem of large liquid surface fluctuations, enabling the liquid level monitoring mechanism to accurately reflect the true liquid level and improve monitoring accuracy.

[0019] The multi-float scheme retains the advantages of the float scheme, such as simple structure, low cost and easy maintenance. On the one hand, it can provide an adjustable alarm threshold function, allowing users to set high and low liquid level alarm points according to actual needs, increasing the applicability and flexibility of the device. On the other hand, it also avoids the problem of no backup scheme due to damage of the single float scheme.

[0020] Before use, the float 8 adheres tightly to the limiting protrusion 7 due to gravity. Then, it floats as the liquid level rises, which is detected by the sensor 9. The sensor 9 obtains the liquid level position information and transmits it to the alarm 1, where a pre-set program determines whether to sound an alarm. Similarly, when the liquid level drops, the movement of the float 8 can also be detected by the sensor 9 and transmitted to the alarm 1.

[0021] In addition to a wired connection, a wireless transmission scheme can also be used between sensor 9 and alarm 1, replacing the original wired transmission method. The connection between sensor 9 and alarm 1 can be changed to a wireless connection, such as through Bluetooth, Wi-Fi, or other wireless communication technologies for data transmission. The wireless transmission scheme reduces wiring complexity and improves the flexibility and portability of the device.

[0022] The sensor 9 can employ a photoelectric conversion scheme, replacing the original signal converter with a photoelectric converter. When the position of the float 8 changes, the photoelectric converter converts the optical signal into an electrical signal for transmission. For example, an LED can be installed on the float 8; when the float 8 reaches a preset position, the LED lights up, and the photoelectric converter converts the optical signal into an electrical signal to trigger the alarm device. The photoelectric conversion scheme has advantages such as fast response speed and strong anti-interference capability.

[0023] Alarm 1 can adopt the following scheme:

[0024] This solution combines audible and visual alarms with remote notification, adding a remote notification function to the existing audible and visual alarm system. When the liquid level reaches a preset threshold, the alarm device not only emits audible and visual alarm signals but also sends remote notifications to relevant personnel via SMS, email, or app push notifications. This solution enables real-time remote monitoring and rapid response to abnormal liquid levels.

[0025] The touchscreen display and operation solution replaces the original simple alarm device interface with a touchscreen. The touchscreen can display real-time liquid level monitoring data, alarm threshold settings, historical alarm records, and other information, and provides a user-friendly human-machine interface. This touchscreen display and operation solution improves the intelligence level of the device, making it easier for users to set parameters and monitor its status.

[0026] Alternatively, an integrated solution can be considered, which integrates components such as the liquid level measuring cylinder 3, float 8, sensor 9, and alarm 1 into a compact device, forming a unified structure. This device can be directly installed on the wine receiving jar without additional installation and debugging steps. The integrated solution simplifies the device structure and improves installation efficiency and reliability.

[0027] In addition to the float-based solution, the following alternatives can be used for liquid level monitoring.

[0028] Magnetic float and Hall sensor solution: A magnetic float replaces the original ordinary float, and a Hall sensor is installed on the inner wall of the liquid level measuring cylinder. When the magnetic float rises and falls with changes in the liquid level, the Hall sensor can sense the change in the magnetic field and convert it into an electrical signal for transmission. The Hall sensor has high sensitivity and accuracy, enabling precise monitoring of the liquid level.

[0029] Capacitive level sensor solution: This solution replaces the dual-float solution with a capacitive level sensor. The sensor detects the liquid level by measuring changes in capacitance. When the liquid level changes, the capacitance value inside the sensor changes accordingly, thus outputting a corresponding electrical signal. Capacitive level sensors offer advantages such as simple structure, small size, and easy installation, and can achieve continuous monitoring of the liquid level.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
