Description

Technical Field

[0001] The invention relates to the technical field of intelligent monitoring equipment, and in particular to an intelligent water level meter with a self-flushing function. Background Art

[0002] Water level gauges are common devices used to monitor liquid heights and are widely used in industrial production, agricultural irrigation, and environmental monitoring. High-temperature and high-pressure mica water level gauges are important devices used to monitor liquid heights under high-temperature and high-pressure environments and are widely used in petrochemical, electric power, metallurgy, and other industries. Under these extreme working conditions, water level gauges must not only provide accurate liquid level measurement, but also ensure the reliability and long-term stability of the equipment. With the continuous development of industrial intelligent technology, modern mica water level gauges have gradually integrated automatic monitoring and remote data feedback functions to achieve real-time monitoring and precise control of liquid levels. However, the measurement accuracy of mica water level gauges is closely related to the cleanliness of the visual window of the equipment. Due to the high temperature and high pressure environment, the visual window of the equipment is easily contaminated by hot steam, dust, or chemicals, resulting in the accumulation of dirt on the visual window, which seriously affects the accuracy of the liquid level reading and may even affect the performance of the sensor. In order to ensure the measurement accuracy of the water level gauge, keeping the visual window clean has become a key issue in equipment design. With the development of intelligent technology, water level gauges have gradually integrated automatic monitoring functions to achieve accurate measurement through real-time data feedback. However, in order to ensure measurement accuracy, the visible window of the water level meter needs to be kept clean to avoid dirt accumulation affecting the reading or sensor performance. Therefore, the development of water level meters with efficient cleaning functions has become a hot topic in the industry.

[0003] In the prior art, some water level gauges achieve cleaning functions by manual wiping or simple spraying. These designs usually rely on external water sources or manual intervention, resulting in low cleaning efficiency and long cleaning time. In addition, some equipment attempts to introduce automated cleaning systems, but the cleaning method is mostly a single spray cleaning, which cannot clean the inner and outer surfaces of the equipment at the same time, and has limited cleaning effect on highly adherent dirt. In addition, during the long-term operation of the equipment, impurities in the air and water flow may cause blockages in the pipes and nozzles, further affecting the reliability of the cleaning system.

[0004] However, the existing technology generally has the following problems: the cleaning process relies on a single method, it is difficult to take into account the cleaning of the inner and outer surfaces of the visual window, and it is easy for impurities to block the pipes or nozzles, resulting in reduced cleaning efficiency and increased maintenance costs. These problems seriously restrict the service life and measurement accuracy of the water level meter. Therefore, there is an urgent need for a water level meter that can efficiently and intelligently clean the inner and outer surfaces of the visual window and has an anti-clogging design to improve the cleaning effect and reliability of the equipment.

[0045] Working principle: When it is needed, an intelligent water level meter with a self-flushing function is encountered. First, condensed water is generated through the cold air machine and the condensation tank, and then the condensed water is transported to the water storage bin for storage. Then the optical sensor detects the dirtiness of the outer wall of the visual window in real time through the change in light intensity reflected by the water flow. The specific model of the optical sensor is: OPB100. If dirt is detected, the condensed water can be transported to the inside of the nozzle through the condensed water delivery pipe, and then the condensed water is discharged to the inner surface of the visual window through the nozzle for flushing and cleaning. In this process, a small part of the condensed water transported through the condensed water delivery pipe will be transported to the inside of the flow cylinder through the side flow pipe, thereby putting pressure on the slide plate, pushing the slide plate to slide on the inner wall of the flow cylinder, and then Pull one end of the connecting harness to move, and then pull the connecting plate to move through the other end of the connecting harness, and then drive the cleaning plate to move on the outer surface of the visual window through the connecting plate to clean, and the cleaning plate is always attached to the outer surface of the visual window through the guidance of the T-shaped guide plate to ensure the cleaning effect. When the slide plate moves to the inside of the flow cylinder, the condensed water will flow downward through the through groove, so that the slide plate is no longer under pressure, and the connecting plate is driven downward under the condition of gravity, so that the slide plate returns to its original position, which is convenient for the next cleaning. At the same time, the water flowing downward is flushed back to the inside of the water level gauge body through the discharge pipe, realizing intelligent and efficient cleaning inside and outside, avoiding long-term accumulation of dirt on the window, and avoiding affecting the performance of the shell or window material;

[0046] In addition, the air supply pipe and the liquid supply pipe are first connected to the external pipeline through the end flange to supply water and air in real time, and then the dual-purpose air valve and the dual-purpose liquid valve are started to cooperate with the three-way pipe to control the water flow and gas delivery in real time. During this process, the air and liquid must first be filtered through the filter plate when passing through the air supply pipe and the liquid supply pipe to avoid impurities damaging the nozzle or pipeline of the cleaning system, and to prevent secondary pollution on the window, ensuring thorough cleaning. After long-term use, the fixing bolts can be driven to realize the disassembly and assembly of the connecting plate, and then the filter plate can be taken out for cleaning or replacement to maintain the filtering effect for a long time.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
