Description

Technical Field

[0001] The present application relates to the technical field of ultrasonic water meters, and specifically discloses an easily detachable ultrasonic water meter. Background Art

[0002] An ultrasonic water meter uses ultrasonic technology to measure water flow velocity and calculate the volumetric flow rate of water flowing through a pipe. The core principle is to use an ultrasonic transducer to compare the propagation time of ultrasound waves flowing downstream and upstream to calculate the water velocity, thereby deriving the flow rate based on the cross-sectional area.

[0003] Normally, an ultrasonic water meter is directly connected to a water pipe network through a flange to monitor the flow in the water pipe network. During the inspection and maintenance of the ultrasonic water meter, it is necessary to first close the main valve of the water pipe official and then disassemble the ultrasonic water meter through the flange. However, when the water outlet position in the water pipe network is high, resulting in the water outlet position being higher than the position of the ultrasonic water meter, some water will remain in the water pipe even if the main valve is closed. When disassembling the ultrasonic water meter, the water pressure and water flow leakage in the water pipe network will also make it difficult to disassemble the ultrasonic water meter and easily cause a waste of water resources. Therefore, in view of this, the inventor provides an easy-to-disassemble ultrasonic water meter to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the problem that in a water pipe network where the water outlet position is higher than the position of the ultrasonic water meter, when the ultrasonic water meter is disassembled, water remains in the water pipe, making it difficult to disassemble the ultrasonic water meter.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the present utility model provides an easily disassembled ultrasonic water meter, including a shell and a detection instrument arranged on the shell, a pressure relief port is provided at the bottom of the shell, and a sealing plate that can cover the pressure relief port is slidingly and sealingly connected to the inner wall of the shell, a through groove covered by the sealing plate is provided on the side wall of the shell, and a connecting block slidingly connected in the through groove is provided on the outer wall of the sealing plate, and an adjustment plate slidingly and sealingly connected to the outer wall of the shell is provided on the end of the connecting block.

[0006] The principles and effects of this basic solution are:

[0007] Compared with the prior art, the present invention provides a pressure relief port at the bottom of the shell, and provides a sealing plate to cooperate with the pressure relief port, and uses an adjustment plate to adjust the position of the sealing plate so that the sealing plate seals or connects the pressure relief port. Therefore, when the ultrasonic water meter is maintained, even if the water outlet position is higher than the position of the ultrasonic water meter, the accumulated water in the water pipe can be discharged by opening the pressure relief port, so as to avoid the problem of difficulty in disassembling the ultrasonic water meter due to leakage of accumulated water. At the same time, the accumulated water can be collected through the pressure relief port, thereby avoiding waste of water resources.

[0008] Furthermore, the outer wall of the housing is provided with a mounting cavity, to which an adjustment rod is rotatably connected. The adjustment rod extends into the mounting cavity and is provided with an adjustment gear. The outer wall of the adjustment plate is located within the mounting cavity and is provided with an arcuate rack that meshes with the adjustment gear. By rotating the adjustment rod, the adjustment gear on the adjustment rod cooperates with the arcuate rack, thereby conveniently adjusting the position of the adjustment plate, thereby adjusting the mating relationship between the sealing plate and the pressure relief port.

[0009] Furthermore, a threaded seat is provided in the mounting cavity, and a threaded section is provided at the end of the adjusting rod to mate with the threaded seat. The threaded section on the adjusting rod cooperates with the threaded seat in the mounting cavity to lock the position of the adjusting rod, thereby preventing the adjusting rod from loosening and causing a misalignment between the sealing plate and the pressure relief port.

[0010] Furthermore, the tooth width of the arc-shaped rack is greater than the length of the threaded section, so as to avoid the arc-shaped rack and the adjusting gear from being separated from each other during the rotation of the adjusting rod.

[0011] Furthermore, the installation cavity includes an adjustment cavity for accommodating the sliding of the adjustment plate and a matching cavity for accommodating the rotation of the adjustment gear, thereby providing protection for both the adjustment plate and the adjustment rod.

[0012] Furthermore, there are two matching cavities symmetrically arranged on both sides of the outer wall of the housing, and the adjusting rod is respectively rotated and connected in the two matching cavities, so that the matching between the adjusting rod and the adjusting plate is more stable.

[0013] Furthermore, a positioning knob is provided on the rod body of the adjusting rod located between the mating cavities. The positioning knob not only facilitates the rotation of the adjusting rod, but also can determine whether the adjusting rod has moved to a specified position based on the position of the positioning knob, thereby determining the mating relationship between the sealing plate and the pressure relief port.

[0018] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0019] The figure marks in the drawings of the specification include: detection pipeline 1, connecting flange 2, detection instrument 3, adjustment chamber 4, matching chamber 5, adjustment rod 6, positioning knob 7, pressure relief port 8, through groove 9, sealing plate 10, connecting block 11, adjustment plate 12, and adjustment gear 13.

[0020] An ultrasonic water meter that is easy to disassemble and assemble, for example Figure 1 As shown: It includes a shell and a detection instrument 3 provided on the shell, wherein the shell includes a detection pipe 1 and connecting flanges 2 provided at both ends of the detection pipe 1. An installation cavity is provided on the outer wall of the shell, and the installation cavity includes an adjustment cavity 4 provided on the side wall of the detection pipe 1 and a matching cavity 5 connected to the adjustment cavity 4. There are two matching cavities 5 and they are symmetrically arranged along the adjustment cavity 4, and an adjustment rod 6 is rotatably installed between the two matching cavities 5. The adjustment rod 6 is located between the two matching cavities 5 and is provided with a positioning knob 7 on the rod body. In this embodiment, a threaded seat is provided at the end of one of the matching cavities 5, and a threaded section that cooperates with the threaded seat is provided at one end of the adjustment rod 6.

[0021] like Figure 2 and Figure 3 As shown, a pressure relief port 8 is provided at the bottom of the detection pipe 1, and a threaded surface is opened at the pressure relief port 8 to facilitate connection with an external pipe. The inner wall of the detection pipe 1 is slidingly sealed with a sealing plate 10 that can cover the pressure relief port 8. The side wall of the detection pipe 1 is provided with a through groove 9 covered by the sealing plate 10. The outer wall of the sealing plate 10 is provided with a connecting block 11 that is slidingly connected in the through groove 9. The end of the connecting block 11 is provided with an adjusting plate 12 that is slidingly sealed and connected to the outer wall of the detection pipe 1. The adjusting plate 12 is located in the adjusting cavity 4 and is provided with an arc-shaped rack on its surface, and the adjusting rod 6 is located in the matching cavity 5. The rod body surface is provided with an adjusting gear 13 that meshes with the arc-shaped rack. The tooth width of the arc-shaped rack is greater than the length of the threaded section to avoid the arc-shaped rack and the adjusting gear 13 from disengaging from each other during the rotation of the adjusting rod 6.

[0022] In this embodiment, when the ultrasonic water meter is in normal use, the sealing plate 10 completely blocks the pressure relief port 8, and the threaded section on the adjusting rod 6 cooperates with the threaded seat in the installation cavity to lock the adjusting plate 12 and the sealing plate 10 as a whole; and when the ultrasonic water meter is maintained and disassembled, the main valve of the water pipe network is first closed, and then an external pipe is used to connect to the pressure relief port 8, and then a wrench or other tool is used to rotate the positioning knob 7 to rotate the adjusting rod 6, so that the threaded section of the adjusting rod 6 and the threaded seat in the installation cavity are gradually loosened. At the same time, the meshing relationship between the adjusting gear 13 and the arc-shaped rack on the adjusting plate 12 is also adjusted to drive the adjusting plate 12 to rotate along the outer wall of the detection pipe 1, that is, drive the seal to rotate along the inner wall of the detection pipe 1, and then make the pressure relief port 8 inside the detection pipe 1 conductive, thereby discharging the accumulated water.

[0023] Compared with the prior art, the present invention provides a pressure relief port 8 at the bottom of the shell, and provides a sealing plate 10 to cooperate with the pressure relief port 8, and uses the adjustment plate 12 to adjust the position of the sealing plate 10, so that the sealing plate 10 seals or connects the pressure relief port 8. Therefore, when the ultrasonic water meter is maintained, even if the water outlet position is higher than the position of the ultrasonic water meter, the accumulated water in the water pipe can be discharged by opening the pressure relief port 8, so as to avoid the problem of difficulty in disassembling the ultrasonic water meter due to leakage of accumulated water. At the same time, the accumulated water can be collected through the pressure relief port 8, thereby avoiding waste of water resources.

[0024] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
