Description

Technical Field

[0001] The utility model relates to the technical field of IC card intelligent water meters, in particular to an antifreeze type IC card intelligent water meter. Background Art

[0002] An IC card smart water meter is a new type of water meter that measures water consumption, transmits water usage data, and settles transactions. In addition to recording and electronically displaying water consumption, smart water meters can also control water consumption according to agreed-upon regulations, automatically calculate tiered water rates, and store water usage data. However, smart water meters are mostly installed outdoors. When outdoor temperatures are too low, water tends to freeze. This condensation can cause damage to the meter's internal metering mechanism, ultimately leading to damage.

[0003] To overcome this shortcoming, CN 208027480 U discloses a frost-resistant smart water meter. The meter includes a meter body with an IC card recognition area and a display screen at the top. An inlet pipe and an outlet pipe are located at either end of the meter body. A second mounting box is located below the meter body, and an upper first mounting box is located above the meter body. The top ends of the second mounting box are fixed to the bottoms of the inlet and outlet pipes, respectively. The bottom ends of the first mounting box are fixed to the tops of the inlet and outlet pipes, respectively. A backing plate is fixed to the inner wall of the bottom of the second mounting box, and a heating layer is fixed to the top of the backing plate. The heating layer covers the exterior of the meter body and comprises an insulating layer fixed to the outer wall of the meter body and a resistance wire fixed to the insulating layer. This design is intended to prevent water freezing within the meter body, which could damage the meter, extend the meter's service life, and expand the applicability of smart water meters. However, the following problems remain: 1. Prolonged power consumption wastes energy; 2. Damaged resistance wires cannot be detected promptly and are inconvenient to replace. Summary of the Invention

[0004] The purpose of the utility model is to provide a structured and reliable antifreeze IC card smart water meter that solves the above problems, which saves electric energy on the one hand and ensures timely and convenient maintenance on the other hand, thereby ensuring the normal operation of the smart water meter.

[0005] The technical solution of the utility model is:

[0006] A freeze-proof IC card smart water meter comprises an IC card smart water meter body, and water inlet and outlet pipes arranged on both sides of the IC card smart water meter body. An insulation housing is fixed to the outer side of the IC card smart water meter body, and a transparent window corresponding to the IC identification area and display screen of the IC card smart water meter body is provided on the top of the insulation housing. The technical key points are: the insulation housing is provided with an inlet-side sheath wrapped around the outer periphery of the water inlet pipe and a water outlet-side sheath wrapped around the outer periphery of the water outlet pipe. A first temperature sensor is fixed to the inlet-side sheath, and a second temperature sensor is fixed to the outlet-side sheath. Detection heads of the first and second temperature sensors are inserted into the corresponding water inlet and outlet pipes. An insulation filler is provided within the insulation housing to surround the IC card smart water meter body. The insulation filler is provided with a plurality of heating cavities surrounding the IC card smart water meter body. Heating rods are provided in the heating cavities, and the connection terminals of the heating rods are located on the outer wall of the insulation housing.

[0007] The above-mentioned antifreeze type IC card smart water meter has four groups of heating chambers, which are composed of two groups of heating chambers located on both sides of the lower side of the IC card smart water meter body and two groups of heating chambers located on both sides of the upper side of the IC card smart water meter body. The wiring terminals of each heating rod in each group of heating chambers are electrically connected using the same wiring board, and the edges of each wiring board are connected and fixed to the insulation shell, which is convenient for disassembly and replacement of the heating rods.

[0008] The beneficial effects of the utility model are:

[0009] 1. The detection heads of the first temperature sensor and the second temperature sensor monitor the water flow temperature of the water inlet pipe and the water outlet pipe in real time, providing feedback basis for the heating temperature of the heating rod. When the first temperature sensor detects that the water flow temperature is low, the heating rod is powered for heating. When the second temperature sensor detects that the water flow temperature rises to the set temperature range, the heating is stopped, thereby saving electricity.

[0010] 2. The insulation filler in the insulation shell passes through multiple heating chambers and has a built-in heating rod. If the heating rod is damaged and fails, the second temperature sensor will feedback the temperature after power is removed, indicating that the heating rod is not heating or the heating effect is significantly poor, which will promptly remind the staff to replace the heating rod to prevent the water meter from freezing. The heating rod can be pulled out through the outer wall of the insulation shell for easy maintenance and ensure the normal operation of the smart water meter. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] The utility model is described in detail according to the accompanying drawings.

[0015] like Figure 1 、 Figure 2 As shown, the antifreeze IC card smart water meter includes an IC card smart water meter body 10, and water inlet pipes 9 and water outlet pipes 12 arranged on both sides of the IC card smart water meter body 10. An insulating housing 2 is fixed to the outer side of the IC card smart water meter body 10. A transparent window 1 is provided on top of the insulating housing 2, corresponding to the IC identification area 3 and display screen 4 of the IC card smart water meter body.

[0016] The thermal insulation housing 2 is provided with an inlet-side sheath 8 wrapped around the outer circumference of the water inlet pipe 9 and an outlet-side sheath 13 wrapped around the outer circumference of the water outlet pipe 12. A first temperature sensor 7 is fixed to the inlet-side sheath 8, and a second temperature sensor 11 is fixed to the outlet-side sheath 13. The detection heads of the first temperature sensor 7 and the second temperature sensor 11 are inserted into the corresponding water inlet pipe 9 and water outlet pipe 12. The thermal insulation housing 2 is provided with an insulating filler 6 surrounding the IC card smart water meter body 10. The insulating filler 6 is provided with multiple heating cavities around the IC card smart water meter body 10. The heating cavities are provided with heating rods 5. The connection terminals of the heating rods 5 are located on the outer wall of the thermal insulation housing 2.

[0017] In this embodiment, the number of the heating chambers is four groups, consisting of two groups of heating chambers located on both sides below the IC card smart water meter body 10 and two groups of heating chambers located on both sides above the IC card smart water meter body 10. The wiring terminals of each heating rod 5 in each group of heating chambers are electrically connected using the same wiring board 14, and the edges of each wiring board 14 are connected and fixed to the insulation shell 2, which facilitates the disassembly and replacement of the heating rods.

[0018] Working principle:

[0019] During use, the first temperature sensor 7 and the second temperature sensor 11 monitor the water temperature of the water inlet pipe 9 and the water outlet pipe 12 in real time. When the first temperature sensor 7 detects that the water temperature is low, the four groups of heating rods 5 are powered on for heating simultaneously or two of them are selected for heating. When the second temperature sensor 11 detects that the water temperature rises to the set temperature range, heating stops, thereby saving energy. If power is still drawn but the second temperature sensor 11 detects that the water temperature does not rise, it indicates that the heating rod 5 is damaged, reminding the staff to replace the heating rod 5 in time.
