Description

Technical Field

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

[0002] Smart water meters are a new type of metering instrument based on traditional mechanical water meters, integrating modern sensing technology, microelectronics technology, and data communication technology. They achieve accurate water consumption measurement and remote management through two-way data interaction. In winter, the glass cover of smart water meters often cracks due to freezing water, causing leaks, especially in cold regions. Current methods involve wrapping the outside of the smart water meter with insulation material. However, due to the irregular shape of the smart water meter casing, it is difficult to tightly bind the insulation material to the outside, resulting in large gaps between the insulation material and the smart water meter, which cannot effectively reduce the risk of freezing. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides an intelligent water meter antifreeze device.

[0004] The technical solution of this utility model is as follows:

[0005] A smart water meter antifreeze device is installed on the outside of the smart water meter housing. It includes an upper insulation housing and a lower insulation housing that are detachably connected to the housing in the vertical direction. The upper insulation housing has an openable and closable top cover. The inner side of the top cover has a first insulation cotton that is adapted to the upper part of the smart water meter. High-density closed-cell sponge strips are provided on both sides of the first insulation cotton. The high-density closed-cell sponge strips are located in the gap between the upper insulation housing and the opposite sides of the smart water meter housing. A first leakage detection element is provided on the side of the first insulation cotton corresponding to the glass cover of the smart water meter.

[0006] The lower insulation shell is located below the smart water meter, and a second insulation cotton is installed inside it. The upper surface of the second insulation cotton is in contact with the lower part of the smart water meter.

[0007] Furthermore, both the upper and lower insulation shells have insulation layers on their inner walls.

[0008] The upper and lower insulation shells are connected by a snap-fit ​​structure, wherein the upper insulation shell is provided with upper arc-shaped clamping pipes on both sides along the water flow direction inside the smart water meter, and the lower insulation shell is provided with lower arc-shaped clamping pipes on both sides that are adapted to the upper arc-shaped clamping pipes. The upper and lower arc-shaped clamping pipes are snapped onto the water pipe by snap-fit ​​components.

[0009] The specific structure of the aforementioned snap-fit ​​component is as follows: the snap-fit ​​component includes an arc-shaped rod and connectors at both ends. The arc-shaped rod is arranged along the arc direction of the upper arc-shaped clamping pipe fitting. The connectors pass through the arc-shaped rod and the upper arc-shaped clamping pipe fitting in sequence and are detachably connected to the lower arc-shaped clamping pipe fitting. Both the upper and lower arc-shaped clamping pipe fittings are provided with connecting holes that are compatible with the connectors. The connecting holes can be threaded holes, and the connectors can be fastening bolts that are compatible with the threaded holes. By setting two connectors on the arc-shaped rod, it is possible to prevent the loss of a single connector and to facilitate the simultaneous fastening connection of the upper and lower arc-shaped clamping pipe fittings on the same side of the water pipe.

[0010] Furthermore, the lower end of the connector is provided with a guide rod coaxial with it.

[0011] Preferably, a sealing strip is provided between the upper insulation shell and the lower insulation shell.

[0012] Preferably, the lower insulation shell has a base plate, the second insulation cotton is placed on the base plate, and a second leakage detection element is provided on one side of the second insulation cotton.

[0013] Preferably, the outer wall of the water pipe is fitted with an insulation sleeve, the insulation sleeve has a notch along its length, and the insulation sleeve is located inside the upper arc-shaped clamping fitting and the lower arc-shaped clamping fitting.

[0014] The beneficial effects of this utility model are as follows:

[0015] The upper insulation shell contains a first insulation cotton that can insulate the upper part of the smart water meter, and the lower insulation shell contains a second insulation cotton that can insulate the lower part of the smart water meter. In addition, the inner walls of both the upper and lower insulation shells have insulation layers, so that the shell formed by the upper and lower insulation shells can insulate the smart water meter and some water pipes inside, reducing the possibility of freezing due to low temperature or cracking of the glass cover of the smart water meter, which could lead to water leakage or malfunction.

[0016] One side of the top cover is hinged to one side of the upper insulation shell, and the opposite side is snapped into the upper insulation shell. This design makes it easy to quickly open the top cover and the first insulation cotton covering the smart water meter's dial, allowing for observation of the smart water meter's status and data.

[0017] Density closed-cell sponge strips are placed on both sides of the smart water meter to fill the gap between the smart water meter and the upper insulation shell, thereby improving the insulation performance. The density closed-cell sponge strips are softer than the first insulation cotton and have a greater degree of deformation performance. Therefore, during installation, the density closed-cell sponge strips can be stuffed into the gap between the smart water meter and the upper insulation shell.

[0018] The upper and lower arc-shaped clamping fittings are used to detachably connect the upper and lower insulation shells, specifically through snap-fit ​​connections. Because an insulation sleeve covering the water pipe is located between the upper and lower arc-shaped clamping fittings, and this sleeve is made of soft material, it is not convenient to stably fix the upper and lower arc-shaped clamping fittings on their outer sides for connection. Therefore, a guide rod is provided at the lower end of the connector of the snap-fit ​​fitting. The guide rod is pre-inserted into the connection holes of the upper and lower arc-shaped clamping fittings to pre-position them. By rotating the corresponding connector, the upper and lower arc-shaped clamping fittings can be quickly installed. This can be operated by a single person without the need for two workers.

[0019] If the glass cover of the smart water meter cracks when used in extremely cold environments, a first leakage detection device can quickly detect the leakage caused by the cracked glass cover. The first leakage detection device can be a contact leakage sensor, etc. The first leakage detection device is electrically connected to an external control host and can promptly send the detected data to the control host. The control host converts the data and alerts the staff to the smart water meter leakage through alarms or other means.

[0020] If a leak occurs in the smart water meter or other parts where the smart water meter connects to the water pipe, the first leak detection device, located on the top of the smart water meter, cannot detect the leak in a timely manner. Therefore, a second leak detection device is installed inside the second insulation cotton below the smart water meter. Attached Figure Description

[0031] See Figure 1 , Figure 2 and Figure 4 As shown, an antifreeze device for a smart water meter 1 is installed on the outside of the housing of the smart water meter 1. It includes an upper insulation housing 2 and a lower insulation housing 3 that are detachably connected to the housing in the vertical direction. The inner walls of the upper insulation housing 2 and the lower insulation housing 3 are provided with insulation layers. The insulation layers are made of insulation material, which is the prior art and is not shown in the figure.

[0032] See Figure 1 and Figure 6 As shown, the upper part of the upper insulation shell 2 is provided with an openable cover 21. The inner side of the cover 21 is provided with a first insulation cotton 4 that is adapted to the upper part of the smart water meter 1. High-density closed-cell sponge strips 5 are provided on both sides of the first insulation cotton 4. The high-density closed-cell sponge strips 5 are located in the gap between the corresponding sides of the smart water meter 1 shell and the upper insulation shell 2. A first leakage detection element 6 is provided on the side of the first insulation cotton 4 corresponding to the glass cover of the smart water meter 1. If the glass cover of the smart water meter 1 cracks when used in extremely cold places, the first leakage detection element 6 can quickly respond to the leakage caused by the cracked glass cover. The first leakage detection element 6 can be a contact leakage sensor, etc. The first leakage detection element 6 is electrically connected to an external control host and can promptly send the detected data to the control host. The control host converts the data and alerts the staff of the smart water meter 1 leakage through alarm or other means.

[0033] One side of the top cover 21 is hinged to one side of the upper insulation shell 2, and the opposite side is snapped into the upper insulation shell 2. This arrangement makes it easy to quickly open the top cover 21 and the first insulation cotton 4 covering the dial of the smart water meter 1, so that the status and data of the smart water meter 1 can be observed.

[0034] The density closed-cell sponge strips are set on both sides of the smart water meter 1, which can fill the gap between the smart water meter 1 and the upper insulation shell 2, and improve the insulation performance. The density closed-cell sponge strips are softer than the first insulation cotton 4 and have a greater degree of deformation performance. Therefore, during installation, the density closed-cell sponge strips can be stuffed into the gap between the smart water meter 1 and the upper insulation shell 2.

[0035] The lower insulation shell 3 is located below the smart water meter 1, and a second insulation cotton 7 is installed inside it. The upper surface of the second insulation cotton 7 abuts against the lower part of the smart water meter 1. The lower insulation shell 3 has a base plate, and the second insulation cotton 7 is installed on the base plate. A second leakage detection element 14 is provided on one side of the second insulation cotton 7. If water leakage occurs in the smart water meter 1 or other parts where the smart water meter 1 is connected to the water pipe 16, the first leakage detection element 6 is located on the upper part of the smart water meter 1 and cannot detect the leakage in time. Therefore, a second leakage detection element 14 is installed inside the second insulation cotton 7 below the smart water meter 1.

[0036] The upper insulation shell 2 and the lower insulation shell 3 are connected by a snap-fit ​​structure. The upper insulation shell 2 has upper arc-shaped clamping fittings 8 on both sides along the water flow direction inside the smart water meter 1. The lower insulation shell 3 has lower arc-shaped clamping fittings 9 on both sides that are adapted to the upper arc-shaped clamping fittings 8. The upper arc-shaped clamping fittings 8 and the lower arc-shaped clamping fittings 9 are snapped onto the water pipe 16 by snap-fit ​​fittings. Two sets of snap-fit ​​fittings are provided on the same side of the upper arc-shaped clamping fittings 8 and the lower arc-shaped clamping fittings 9 for a stable connection between the upper insulation shell 2 and the lower insulation shell 3.

[0037] See Figure 3 As shown, the specific structure of the above-mentioned snap-fit ​​component is as follows: the snap-fit ​​component includes an arc-shaped rod 10 and connectors 11 at both ends. The arc-shaped rod 10 is arranged along the arc direction of the upper arc-shaped clamping tube 8. The two ends of the arc-shaped rod 10 are provided with elongated holes 101 in the vertical direction. The connectors 11 are inserted into the elongated holes 101. A baffle 17 is threadedly connected to the middle of the connector 11. The outer diameter of the baffle 17 is larger than the inner diameter of the elongated hole 101. When the connector 11 is inserted into the elongated hole 101, the baffle 17 is located below the elongated hole 101 to prevent the connector 11 from disengaging from the elongated hole 101.

[0038] The connector 11 passes through the arc-shaped rod 10 and the upper arc-shaped clamping pipe 8 in sequence and is detachably connected to the lower arc-shaped clamping pipe 9. Both the upper arc-shaped clamping pipe 8 and the lower arc-shaped clamping pipe 9 are provided with connecting holes 18 that are adapted to the connector 11. The connecting holes 18 can be threaded holes, and the connector 11 can be a fastening bolt adapted to the threaded holes. By setting two connectors 11 on the arc-shaped rod 10, it is possible to prevent the loss of a single connector 11 and facilitate the simultaneous fastening connection of the upper arc-shaped clamping pipe 8 and the lower arc-shaped clamping pipe 9 on the same side of the water pipe 16.

[0039] See Figure 5 As shown, the outer wall of the water pipe 16 is fitted with an insulation sleeve 15. The insulation sleeve 15 has a notch 151 along its length. The notch 151 facilitates the installation of the protective sleeve on the water pipe 16. The insulation sleeve 15 is located between the inner wall of the upper arc-shaped clamping pipe fitting 8 and the lower arc-shaped clamping pipe fitting 9 and the outer wall of the water pipe 16.

[0040] The upper arc-shaped clamping fitting 8 and the lower arc-shaped clamping fitting 9 are used to detachably connect the upper insulation shell 2 and the lower insulation shell 3, specifically through snap-fit ​​connections. Because an insulation sleeve 15 covering the water pipe 16 is provided between the upper arc-shaped clamping fitting 8 and the lower arc-shaped clamping fitting 9, and the insulation sleeve 15 is made of soft material, it is not convenient to stably fix the upper arc-shaped clamping fitting 8 and the lower arc-shaped clamping fitting 9 on the outside for connection. Therefore, a guide rod 12 is provided at the lower end of the connector 11 of the snap-fit ​​connection. The guide rod 12 is inserted into the connection hole 18 opened in the upper arc-shaped clamping fitting 8 and the lower arc-shaped clamping fitting 9 in advance to pre-position the upper arc-shaped clamping fitting 8 and the lower arc-shaped clamping fitting 9. By rotating the corresponding connector 11, the upper arc-shaped clamping fitting 8 and the lower arc-shaped clamping fitting 9 can be quickly installed. This can be operated by a single person without the need for two workers to cooperate.

[0041] See Figure 6 and Figure 7 As shown, in order to improve the sealing effect at the connection between the upper insulation shell 2 and the lower insulation shell 3, a sealing strip 13 is provided between the upper insulation shell 2 and the lower insulation shell 3.
