However, the traditional monitoring methods for the water seal liquid level of gas drainers mostly rely on manual regular inspections, which are not only inefficient but also difficult to ensure the accuracy and timeliness of monitoring. Moreover, the existing intrinsically safe monitoring equipment is costly. Therefore, it is of great practical significance to develop an efficient and accurate monitoring and alarm system for the water seal liquid level of gas drainers. Summary of the Utility Model

[0025] The following details the specific embodiments of the embodiments of the present utility model with reference to the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the embodiments of the present utility model and do not limit the embodiments of the present utility model.

[0026] As Figure 1 is the gas drainer provided by the embodiment of the present utility model. The embodiment of the present utility model provides a monitoring and warning device for the water seal liquid level of a gas drainer. The monitoring and warning device includes: a weighing sensor installed inside the bottom of the gas drainer for real-time measurement of the weight of the water seal liquid in the gas drainer; a processor connected to the weighing sensor for converting the weight data of the water seal liquid in the gas drainer into liquid level data; and an alarm connected to the processor for controlling the alarm to give an alarm prompt when the liquid level data obtained by the processor is lower than a preset liquid level.

[0027] In metallurgical enterprises, the gas condensate drainer is a protective device for gas pipelines. When the gas pressure in the pipeline exceeds the limit value, the gas will break through the drainer and cause the gas to overflow to reduce the gas pressure. The water level in the water seal chamber of the drainer is an important indicator determining the safe operation of the gas system. Once the drainer lacks water and cannot seal the gas, it is very easy to cause gas leakage and trigger gas poisoning accidents for the surrounding personnel. Since the gas drainers are distributed along the gas pipeline, usually the water seal liquid level can only rely on manual regular spot checks. When the liquid level drops due to abnormal conditions, relevant personnel cannot be notified in time, and dangerous situations such as gas leakage may occur.

[0028] Aiming at the defects of the existing technical solutions, the present invention aims to provide a monitoring and early warning system for the water seal liquid level of a gas drainer. This system can monitor the change of the water seal liquid level in real time and automatically issue an alarm prompt when the liquid level is lower than the preset value, thereby reducing the labor intensity of manual spot checks, improving the safety of the gas drainer, and reducing the risk of gas leakage accidents.

[0029] In some embodiments, the embodiments of the present utility model take Figure 1 the gas drainer 101 in Figure 1 as an example for explanation. The liquid level of the water seal liquid 102 (usually referring to condensate water) in the right chamber in

[0030] is the object monitored in the embodiments of the present utility model. Currently, the method for measuring the liquid level of the water seal liquid 102 of the gas drainer in the industry mostly uses manual regular measurement with tools such as wooden sticks or bamboo poles. During measurement, the operator needs to open the upper plug of the gas drainer, insert the wooden stick or bamboo pole into the cylinder for water level detection, and then judge whether the water seal liquid level is normal by comparing the measurement result with the preset value.

[0031] However, manual monitoring has the following disadvantages: Disadvantage 1: The measurement process is cumbersome, requiring manual operation, and the measurement accuracy is greatly affected by human factors; Disadvantage 2: Since it is necessary to open the upper plug of the drainer for measurement, there is a risk of gas leakage; Disadvantage 3: There are a large number of gas drainers in the factory area, and the intervals are very large. Manual detection consumes a great deal of time and physical strength. Disadvantage 4: Due to regular spot checks, the change of the water seal liquid level cannot be monitored in real time, and it is difficult to detect abnormal situations in time and take corresponding treatment measures.

[0032] Meanwhile, considering that the inner chamber of the gas condensate drainer belongs to an explosive gas environment area, laser lateral position is not suitable. In addition, for the traditional electrode type liquid level detection method, intrinsically safe equipment needs to be selected, resulting in a high cost. At the same time, due to the impure quality of the gas condensate water, accompanied by a large amount of tar-like flocs, the traditional float type measurement is not applicable, and it is easy to cause the float to be blocked.

[0033] Therefore, in view of the drawbacks of the above sensors, the embodiments of the present invention specifically select a weighing sensor as the monitoring device of the embodiments of the present utility model. This measurement method not only has high accuracy but also a fast response speed, and can reflect the change of the water seal water storage in real time. Especially, the detection principle is mechanical, which is particularly suitable for the explosive gas environment where the device is located.

[0034] Weighing sensors usually adopt high-precision and high-stability weight sensors to ensure the accuracy of measurement data. The processor is responsible for receiving the original data transmitted by the weighing sensor and performing processing such as filtering, amplification, and conversion, so as to better utilize these data subsequently. The weighing sensor is in direct contact with the bottom of the water seal to ensure that the change in the weight of water can be accurately sensed.

[0035] Such as Figure 2 is a schematic structural diagram of the monitoring and warning device provided by the embodiments of the present utility model. In the embodiments of the present utility model, the weighing sensor 201 is installed inside the bottom of the gas drainer (such as Figure 1 ), and the weighing sensor 201 is sealed at the bottom of the gas drainer by existing technical means to measure the weight of the water (i.e., Figure 1 the water seal liquid in the right chamber) in the gas drainer in real time, and transmit the obtained weight data of the water seal liquid to the processor 202 ( Figure 1 not shown in the figure). The processor 202 converts the weight data of the water seal liquid into corresponding liquid level data. For example, conduct multiple tests in advance to fit the corresponding relationship between the weight of the water seal liquid and the liquid level, and set the corresponding algorithm according to the corresponding relationship between the weight of the water seal liquid and the liquid level. The processor uses the algorithm corresponding to the relationship between the weight data and the liquid level data to convert the weight data of the water seal liquid in the gas drainer into liquid level data. Thus, the weight data of the water seal liquid is obtained through the weighing sensor 201, and the processor 202 converts the weight data into liquid level data.

[0036] Suppose the critical value is when the liquid level of the water in the gas drainer is 100 cm. When it is lower than this critical value, the gas may not be sealed, easily causing gas leakage. Thus, the preset liquid level can be set to 85 cm, that is, once the preset liquid level data obtained by the processor 202 is lower than 85 cm, an alarm prompt signal is sent to the alarm 203 to indicate an alarm, so as to timely remind relevant personnel to inject the water seal liquid in a professional manner in time.

[0037] In the embodiment of the present utility model, a monitoring and warning device 20 is jointly composed of a weighing sensor 201, a processor 202, and an alarm 203, achieving the effect of automatically monitoring the water seal liquid level, without relying too much on manual monitoring, improving the accuracy and efficiency of monitoring. Moreover, the present utility model is specially designed to use a weighing sensor 201 and set it inside the bottom of the gas drainer 101. On the one hand, it solves the problem of high cost of intrinsically safe equipment for electrode type liquid level detection. On the other hand, it solves the problem of easy blockage in traditional float type measurement. Additionally, considering the usage scenario of the gas drainer and avoiding laser type position sensors, the weighing sensor used in this application is safer.

[0038] Further, the number of the weighing sensors is multiple, and the multiple weighing sensors are installed at the bottom of the gas drainer in an array manner.

[0039] In some embodiments, in order to improve the monitoring accuracy, multiple weighing sensors are selected in the embodiment of the present utility model, and the multiple weighing sensors are installed inside the bottom of the gas drainer in an array manner. The installation position is the same as the Figure 1 position, such as Figure 3 The multiple weighing sensors are arranged in an array. These sensors are evenly distributed at different positions at the bottom of the gas drainer to form a multi-point measurement network, improving the measurement accuracy. The average value of the multiple weight data obtained by the multiple weighing sensors can be calculated, and the processor converts the averaged weight data into liquid level data. When the liquid level data is lower than the preset liquid level, the control alarm gives an alarm prompt. It should be noted that the embodiment of the present utility model is applicable to various gas drainers with a structure similar to that provided in this embodiment.

[0040] Further, the processor further includes a temperature compensation module, and the temperature compensation module is installed in the gas drainer and is used to automatically adjust the weight data measured by the weighing sensor according to the real-time change of the water temperature in the gas drainer.

[0041] In some embodiments, considering that the usage environment of the gas drainer is generally outdoors, the temperature in the gas drainer will change with the seasons. Therefore, in the embodiment of the present utility model, the processor further includes a temperature compensation module to reduce the influence of temperature on the measurement accuracy and improve the accuracy of liquid level calculation.

[0042] Further, the monitoring and warning device further includes: a data recording module, and the data recording module is respectively connected to the alarm and the weighing sensor and is used to record and store the alarm records of the alarm and the operation status information of the weighing sensor in real time.

[0043] In some embodiments, for subsequent data analysis and fault diagnosis, the monitoring and warning device provided by the embodiments of the present utility model further includes a data recording module (not shown in the figure). The data recording module is respectively connected to the alarm and the weighing sensor, and is used to record and store the alarm records of the alarm and the operation status information of the weighing sensor in real time. For example, when the monitoring and warning device fails, the cause of the failure can be analyzed by querying the data in the data recording module.

[0044] Furthermore, the monitoring and warning device further includes: a pressure sensor, which is installed inside the bottom of the gas drainer and is used to measure the pressure of the water seal liquid in the gas drainer in real time; the pressure sensor is also connected to the processor and is used to convert the pressure data into liquid level data.

[0045] In some embodiments, in order to improve the accuracy of detection, the monitoring and warning device may further include a pressure sensor (not shown in the figure). The installation position of the pressure sensor is the same as that of the weighing sensor, and both are installed inside the bottom of the gas drainer. When the amount of the water seal liquid inside the gas drainer decreases, the corresponding pressure also gradually decreases. Therefore, it can be determined that there is a positive relationship between the liquid level and the pressure. Specifically, the corresponding relationship between the pressure and the liquid level in the water seal liquid can be fitted by means of multiple tests, and a corresponding algorithm is designed according to the corresponding relationship. The processor converts the pressure signal into a liquid level signal according to the designed algorithm, and the liquid level signal obtained by averaging the liquid level signal obtained from the pressure signal and the liquid level signal obtained by converting the weight data is used as the liquid level data. When the obtained liquid level data is lower than the preset liquid level, the alarm is controlled to give an alarm prompt.

[0046] The embodiments of the present utility model further add a pressure sensor on the basis of the weighing sensor, which improves the accuracy of liquid level detection.

[0047] Furthermore, the weighing sensor is also installed outside the bottom of the gas drainer and is used to measure the weight of the gas drainer and the water seal liquid in real time.

[0048] Furthermore, the processor is also used to convert the weight data of the gas drainer and the water seal liquid into liquid level data.

[0049] In some embodiments, for the convenience of implementation and installation, the embodiments of the present utility model can also install the weighing sensor on the outer side of the bottom of the gas drainer, that is, the whole weighing sensor is installed below the weighing sensor to measure the weight of the gas drainer and the water seal liquid. Specifically, the method of multiple tests can also be adopted to measure the weight of the gas drainer when the water seal liquid is at different liquid levels, so as to calculate the corresponding relationship between the weight of the gas drainer and the liquid level of the water seal liquid, and the corresponding relationship is also a positive relationship. By setting the corresponding algorithm according to this relationship, the liquid level of the water seal liquid can be calculated according to the weight of the weighing sensor. The other principles and effects are similar to those of the above embodiments and will not be elaborated here.

[0050] Further, the monitoring and warning device further includes: a plurality of wireless transmission modules. The weighing sensor and the processor are respectively installed with wireless transmission modules, and data is transmitted between the weighing sensor and the processor through the wireless transmission modules.

[0051] Further, the wireless transmission module is a wifi transmission module or a zigbee transmission module.

[0052] In some embodiments, the embodiments of the present utility model further include a plurality of wireless transmission modules (not shown in the figure), and data transmission is realized through the wireless transmission modules. The wireless transmission module can specifically be a wifi transmission module or a zigbee transmission module, which has the advantages of low cost and fast transmission.

[0053] Further, the weighing sensor is a waterproof weighing sensor.

[0054] In some embodiments, considering the use environment of the weighing sensor in the solution of the present utility model, a waterproof weighing sensor is specifically selected.

[0055] Through the above technical solution, the monitoring and warning device includes: a weighing sensor installed inside the bottom of the gas drainer for real-time measuring the weight of the water seal liquid in the gas drainer; a processor connected to the weighing sensor for converting the weight data of the water seal liquid in the gas drainer into liquid level data; and an alarm connected to the processor for giving an alarm prompt when the liquid level data obtained by the processor is lower than a preset liquid level.

[0056] In the embodiment of the present utility model, a weighing sensor is installed inside the bottom of the gas drainer to measure the weight of the water seal liquid in the gas drainer in real time. The weight data collected by the weighing sensor is transmitted to a processor, and the processor converts the weight data of the water seal liquid into liquid level data according to the preset correspondence between the weight of the water seal liquid and the liquid level of water. When the obtained liquid level data is lower than the preset liquid level, an alarm prompt is sent through an alarm to prompt relevant personnel to inject water into the gas drainer in time. The embodiment of the present utility model obtains the liquid level information in real time and sends an alarm prompt in time when the liquid level information is lower than the preset liquid level, improving the accuracy and efficiency of monitoring. Moreover, the present utility model specifically selects a weighing sensor to obtain the liquid level information, solves the problem that the existing liquid level sensor is greatly affected by temperature in the prior art, and improves the accuracy of monitoring.
