Description

Technical Field

[0001] This utility model relates to the field of ultrasonic water meter technology, specifically to an antifreeze ultrasonic water meter. Background Technology

[0002] An ultrasonic water meter is a new type of water meter that detects the time difference caused by the change in speed of an ultrasonic beam as it propagates upstream and downstream in water, analyzes and processes the data to obtain the water flow rate, and then calculates the water flow rate.

[0003] Although ultrasonic water meters are highly practical, their internal structural components can freeze in cold weather, causing them to malfunction. Therefore, in some areas with cold winters, ultrasonic water meters are wrapped with insulation materials. However, the insulation materials are often secured with ropes or wires, making it inconvenient to open the meter to view the display and hindering normal use. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an antifreeze ultrasonic water meter, comprising an ultrasonic water meter with a casing fixed to it. Inside the casing, multiple No. 2 and No. 3 insulation cotton blocks are respectively inserted, wrapping the outer surface of the ultrasonic water meter. A sealing cap is connected to the top of the casing, positioned above the display of the ultrasonic water meter. A quick-release mechanism is also included, mounted on the sealing cap, for securing the sealing cap to the casing.

[0005] Furthermore, a first insulating cotton block is fixed to the lower surface of the sealing cover, and the first insulating cotton block has a central notch larger than the length and width of the ultrasonic water meter display.

[0006] Furthermore, multiple fixing holes are provided at the top of the outer casing.

[0007] Furthermore, a pair of rectangular elongated holes are provided at both ends of the sealing cap.

[0008] Furthermore, the quick-release mechanism includes a limiting rod fixed to a first fixing plate and a second fixing plate, and a movable plate slidably sleeved on the limiting rod. Multiple first fixing plates and multiple second fixing plates are respectively fixed at both ends of the lower surface of the sealing cover. Two movable plates located on the same side are symmetrically distributed. Insertion rods adapted to the fixing holes are fixed on the opposite surfaces of these two movable plates. A through hole of the same size and aligned with the fixing hole is provided on the first fixing plate.

[0009] Furthermore, it also includes push springs, with multiple push springs respectively corresponding to the outer side of the limiting rod and respectively connected to the second fixed plate and the moving plate. The moving plate can move by the elastic force of the push springs. A guide slide rod is fixed on the first fixed plate and the second fixed plate, and the guide slide rod is slidably connected to the moving plate.

[0010] Furthermore, a connecting plate is fixed to the upper surface of the movable plate, and the connecting plate can move within the length range of the rectangular elongated hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By incorporating an outer casing, a sealing cap, a first fixing plate, a second fixing plate, a limiting rod, a guide slide rod, a moving plate, an insertion rod, a pushing spring, and a connecting plate, the antifreeze device on this ultrasonic water meter is designed for easy disassembly. By pinching the connecting plates on both sides of the sealing cap with both hands, the outer casing can be separated from the sealing cap, thus exposing the internal ultrasonic water meter display. This facilitates counting and inspection by staff and improves practicality. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0020] like Figures 1-4 This embodiment provides an antifreeze ultrasonic water meter, including an ultrasonic water meter 1. A casing 2 is fixed to the ultrasonic water meter 1. Multiple No. 2 insulation cotton blocks 8 and multiple No. 3 insulation cotton blocks 9 are inserted inside the casing 2, and the No. 2 and No. 3 insulation cotton blocks 8 and 9 are wrapped around the outer surface of the ultrasonic water meter 1. A sealing cover 3 is connected to the top of the casing 2 and is located above the display of the ultrasonic water meter 1. It also includes a quick-release mechanism, which is installed on the sealing cover 3 and is used to limit and fix the sealing cover 3 to the casing 2.

[0021] In this embodiment, as Figure 2 and Figure 4 As shown, a first insulating cotton block 5 is fixed to the lower surface of the sealing cover 3. The first insulating cotton block 5 has a central notch 6 larger than the length and width of the ultrasonic water meter 1. Multiple fixing holes 7 are opened at the top of the outer shell 2. A pair of square elongated holes 4 are opened at both ends of the sealing cover 3. The quick-release mechanism includes a limiting rod 12 fixed to the first fixing plate 10 and the second fixing plate 11. The first fixing plate 10 is connected to the inner surface of the outer shell 2. A movable plate 14 is slidably sleeved on the limiting rod 12. Multiple first fixing plates 10 and multiple second fixing plates 11 are respectively fixed at both ends of the lower surface of the sealing cover 3. The two movable plates 14 located on the same side are symmetrically distributed. Insertion rods 15 that are adapted to the fixing holes 7 are fixed on the opposite surfaces of the two movable plates 14. A through hole of the same size and aligned with the fixing hole 7 is opened on the first fixing plate 10.

[0022] It also includes push springs 16, with multiple push springs 16 corresponding to the outer rings of the limiting rod 12, and connected to the second fixed plate 11 and the moving plate 14 respectively. The moving plate 14 can move by the elastic force of the push springs 16. A guide slide rod 13 is fixed on the first fixed plate 10 and the second fixed plate 11, and the guide slide rod 13 is slidably connected to the moving plate 14. A connecting plate 17 is fixed on the upper surface of the moving plate 14, and the connecting plate 17 can move within the length range of the square elongated hole 4. During installation, pinching the connecting plates 17 on both sides will bring the two moving plates 14 on the same side closer to each other and compress the push springs 16 respectively, while the insertion rod 15 moves away from the first fixed plate 11. Fixing plate 10, aligning the sealing cap 3 with the outer casing 2, the first fixing plate 10 connects with the inner surface of the outer casing 2 to form a positioning, the first insulation cotton block 5 and the second insulation cotton block 8 are attached to each other, the insertion rod 15 is horizontally aligned with its adjacent fixing hole 7, after the connecting plate 17 is released, the elastic restoring force of the pushing spring 16 causes the moving plate 14 to move, and finally the insertion rod 15 is inserted into the fixing hole 7 respectively, thus completing the installation limit. The multiple second insulation cotton blocks 8 and multiple third insulation cotton blocks 9 inside the device, as well as the first insulation cotton block 5, can play the function of heat preservation and antifreeze. Disassembly is simply the reverse of the above operation, which is convenient to use.

[0023] The implementation principle of the antifreeze ultrasonic water meter in this application embodiment is as follows: During installation, pinch the connecting plates 17 on both sides, and the two moving plates 14 on the same side move closer to each other and compress the push springs 16 respectively. At the same time, the insertion rod 15 moves away from the first fixing plate 10, and the sealing cover 3 is aligned and fastened on the outer casing 2. The first fixing plate 10 is connected to the inner surface of the outer casing 2 to form a positioning. The first insulation cotton block 5 and the second insulation cotton block 8 are attached to each other. The insertion rod 15 is horizontally aligned with its adjacent fixing hole 7. After releasing the connecting plate 17, the elastic restoring force of the push spring 16 causes the moving plate 14 to move, and finally the insertion rod 15 is inserted into the fixing hole 7 respectively, thus completing the installation limit. The multiple second insulation cotton blocks 8 and multiple third insulation cotton blocks 9 inside the device, as well as the first insulation cotton block 5, can play the function of heat preservation and antifreeze. Disassembly is only required by reversing the above operation, which is convenient for use.
