Description

Technical Field

[0001] This utility model relates to the field of ultrasonic heat meter technology, specifically to an anti-corrosion and anti-scaling ultrasonic heat meter. Background Technology

[0002] An ultrasonic heat meter is an instrument that measures flow rate and displays the heat energy released or absorbed by water as it flows through a heat exchange system using ultrasonic methods. It is an electromechanical integrated product based on a microprocessor and a high-precision sensor. Ultrasonic heat meters have been widely promoted and applied due to their advantages such as high measurement accuracy, convenient maintenance, no mechanical parts, and resistance to damage. This type of ultrasonic heat meter includes a hot water flow pipe, an inlet transducer, an outlet transducer, an inlet temperature sensor, and an integrator. It is used in conjunction with the long-term high-temperature application during the heating season.

[0003] According to a search, Chinese patent document, publication number CN221781716U, discloses an ultrasonic heat meter with corrosion and scale prevention. After connecting the detection pipe to the heat pipe, a sliding plate can be pulled to slide along a groove. When the filter slides, it causes the through groove on the surface of the fixed plate to engage with the rotating plate and threaded rod. When the filter slides to the bottom of the groove, it causes the through groove to slide onto the surface of the threaded rod. At this point, the rotating plate can be rotated, and it can be offset from the through groove. When the rotating plate rotates 90°, it can be fixed in place. After the fixed plate is fixed, the filter can be secured. After installation, the filter can filter impurities in the pipe according to its own filtration function, preventing impurities from accumulating and causing scale corrosion. However, during use, long-term use requires cleaning and replacement of the filter. Repeated disassembly and reassembly can easily lead to leakage at the filter outlet, reducing the sealing performance. Furthermore, although the filter can reduce the entry of impurities, they easily adhere to the inner wall, making later cleaning troublesome and time-consuming, and the high corrosiveness still exists.

[0028] Example 1:

[0029] like Figure 1-5 As shown, the present invention provides an anti-corrosion and anti-scaling ultrasonic heat meter, including a detection pipe 1, a heat meter body 2 disposed on the outside of the detection pipe 1, connecting pipes 3 being installed at both ends of the detection pipe 1 by snap-fit, an mounting plate 4 being movably installed on the inside of the connecting pipe 3, a filter screen plate 5 being installed on the side of the mounting plate 4 away from the detection pipe 1 by bolts, a cleaning plate 6 being movably installed on the outside of the mounting plate 4, a rotating shaft 7 being fixedly installed on the top side of the mounting plate 4, and a heat pipe 8 being installed at the end of the connecting pipe 3 away from the detection pipe 1 by snap-fit.

[0030] Specifically, a No. 1 connecting plate 101 is fixedly installed at each of the left and right ends of the testing pipe 1. A No. 1 connecting hole 102 is opened on the left side of the No. 1 connecting plate 101, and there are two sets of four No. 1 connecting holes 102 in total. The advantage is that the four equidistantly arranged No. 1 connecting holes 102 on the No. 1 connecting plate 101 make it easy to align the No. 1 connecting holes 102 with the connecting screws 302 on the connecting pipe 3, and then use nuts to connect and fix them, which facilitates quick and easy disassembly and assembly of the connecting pipe 3 and the testing pipe 1.

[0031] Specifically, mounting plates 301 are fixedly installed at both ends of the connecting pipe 3. Four connecting screws 302 are arranged equidistantly in a ring on the right side of the mounting plates 301. A positioning cylinder 303 is fixedly installed on the side of the mounting plates 301 away from the connecting pipe 3. A movable groove 304 is opened on the inner side of the connecting pipe 3, and the inner side of the connecting pipe 3 is coated with anti-corrosion paint. The advantages are that the connecting screws 302 facilitate the connection and fixation of the connecting pipe 3 to the detection pipe 1 and the heat pipe 8 by using nuts. Moreover, the positioning cylinder 303 helps to extend the length of the positioning cylinder 303, thereby reducing corrosion and dirt on the detection pipe 1. Furthermore, the movable groove 304 facilitates the rotation of the cleaning plate 6.

[0032] Specifically, the mounting plate 4 has a fixing groove 401 on the side away from the detection pipe 1. A screw hole is provided on the inner side of the fixing groove 401, and a filter screen plate 5 is bolted to the inner side of the fixing groove 401. Five adjusting grooves 402 are arranged equidistantly in a ring on the outer side of the mounting plate 4.
