Description

Technical Field

[0001] The utility model relates to the technical field of heat meter equipment, in particular to a high-precision ultrasonic heat meter. Background Art

[0002] High-precision ultrasonic heat meter usually refers to an instrument used to measure fluid flow. It uses ultrasonic technology to measure fluid flow rate and flow rate. This instrument is widely used in industrial fields and laboratories, especially for measuring the flow rate of liquid in pipelines. The working principle of ultrasonic heat meter is to calculate the flow rate and flow rate by using the relationship between the speed of ultrasonic wave propagation in the fluid and the flow speed of the fluid. Usually, the ultrasonic sensor sends ultrasonic pulses, which pass through the fluid and are received by the receiver. By measuring the time of ultrasonic wave propagation in the fluid, the flow rate of the fluid can be calculated. Combined with the cross-sectional area of ​​the pipeline, the flow rate of the fluid can be calculated. Ultrasonic heat meter has the advantages of non-contact measurement, high accuracy, good stability, and is not easily affected by factors such as fluid density and viscosity. Therefore, it is widely used in occasions where accurate measurement of fluid flow is required. In industrial production, ultrasonic heat meter can be used to monitor the flow of liquid or gas in pipelines to help enterprises achieve process control and energy management. In laboratories, ultrasonic heat meter is also commonly used in scientific research experiments and fluid mechanics research.

[0003] As a key device for measuring fluid flow, ultrasonic heat meters play an important role in industrial and laboratory environments. However, one of the current problems is that the dials of these high-precision ultrasonic heat meters are usually exposed to the working environment for a long time and are easily affected by the accumulation of foreign matter such as dust. This accumulation will cause the dial display to be unclear, affecting the operator's accurate reading of the data. What is more serious is that these dust and foreign matter may enter the equipment through the gaps in the dial position, affecting the normal operation of the equipment. In industrial sites or laboratories, there are usually various dusts, particles and other impurities in the environment. These substances will be deposited on the equipment dial with the flow of air. Over time, these dust and foreign matter will accumulate to a certain extent, affecting the clarity and readability of the dial, especially in some harsh working environments, such as places with high temperature, high humidity, dust and oil smoke. This problem is more serious. When dust and foreign matter enter the ultrasonic heat meter, it may affect the normal operation of the instrument's sensors, circuit boards or other key components, which may lead to inaccurate data measurement or equipment failure, thereby affecting production efficiency and data accuracy.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-Figure 2The utility model provides an embodiment: a high-precision ultrasonic heat meter, comprising a shell 1, a dial 5 is arranged inside the shell 1, a top cover 6 is rotatably connected to one side of the shell 1, a sealing disk 1 7 is fixedly connected inside the top cover 6, a sealing disk 2 8 is fixedly connected to one side of the sealing disk 1 7, an outer wall of the sealing disk 2 8 is fixedly connected to a mounting buckle 9, a sealing ring 10 is arranged between the dial 5 and the sealing disk 2 8, the sealing ring 10 is connected to the sealing disk 2 8 through the mounting buckle 9, a docking assembly is arranged at the bottom of the shell 1, and the docking assembly includes a chassis 2, the chassis 2 is fixedly connected to the bottom of the shell 1, and connectors 3 are fixedly connected on both sides of the chassis 2;

[0030] Specifically, in order to effectively prevent dust and other foreign matter from entering the dial 5 position of the high-precision ultrasonic heat meter, an intelligent sealing mechanism is designed. By rotating the top cover 6, the sealing disk 1 7 and the sealing disk 2 8 are respectively sealed with the outer shell 1 and the top cover 6. This design not only effectively prevents the invasion of dust and foreign matter, but also protects the cleanliness and accuracy of the dial 5 position; in this design, the sealing ring 10 is fixed by the mounting buckle 9 to ensure that the gap at the connection between the sealing disk 2 8 and the outer shell 1 is completely closed, further enhancing the overall sealing performance. This intelligent sealing mechanism not only improves the stability and reliability of the equipment, but also extends the service life of the equipment, ensuring the accuracy and reliability of the measurement data.

[0031] Reference Figure 1 and Figure 3 , ultrasonic sensors 4 are arranged on both sides of the chassis 2, springs 11 are arranged inside the ultrasonic sensors 4, one end of the springs 11 is fixedly connected inside the ultrasonic sensors 4, the other end of the springs 11 is fixedly connected to a slider 12, one side of the slider 12 is fixedly connected to a ball 15, the outer wall of the slider 12 is fixedly connected to a limit block 13, the limit block 13 is slidably connected inside to a limit rod 14, and the limit rod 14 is fixedly connected inside the ultrasonic sensor 4;

[0032] Specifically, the connector 3 is designed to be installed at a position where detection is required, providing connection and support for the ultrasonic sensor 4. The ultrasonic sensor 4 is the core component of the system, used to accurately detect the flow rate and direction of the fluid, and uses ultrasonic technology to achieve non-contact measurement. Its precise measurement capability provides key data support for the fluid flow process; when the ultrasonic sensor 4 needs to be replaced and repaired, by directly pulling the ultrasonic sensor 4, the ball 15 is acted upon by force, driving the slider 12 to slide along the limit rod 14 under the restriction of the limit block 13. This process applies pressure to the spring 11, causing the ball 15 to detach from the reserved hole, so that the ultrasonic sensor 4 as a whole can be smoothly pulled out for inspection.

[0033] Working principle: When preventing dust and other foreign matter from entering the dial 5, the top cover 6 can be rotated to make the sealing disk 1 7 and the sealing disk 2 8 seal the joint between the outer shell 1 and the top cover 6 respectively, and the corresponding sealing ring 10 is fixed by the mounting buckle 9 so that it can close the gap at the connection between the sealing disk 2 8 and the outer shell 1, thereby further enhancing the sealing performance. The connector 3 can be installed to the corresponding place that needs to be detected. The corresponding ultrasonic sensor 4 is used to detect the flow rate and flow direction of the fluid, and non-contact measurement is achieved through ultrasonic technology. When the ultrasonic sensor 4 is disassembled and replaced for maintenance, the ultrasonic sensor 4 can be directly pulled so that the ball 15 is forced to drive the slider 12 to slide along the limit rod 14 under the restriction of the limit block 13, thereby squeezing the spring 11, so that the ball 15 is detached from the reserved hole, and the ultrasonic sensor 4 as a whole can be smoothly pulled out for maintenance.
