[Chinese instrument network meter patent] creative limit, instrumentation invention. Today, we introduced a national invention-invented patent—an anti-icing device for smart water meters. The patent was applied for by Tianjin Chenggang Technology Development Co., Ltd. and was authorized on March 13, 2018.
Content Description
The invention relates to the field of water meters, in particular to an anti-freezing device for smart water meters.
Background of the invention
Every winter, the temperature dropped to freezing, which could easily lead to freezing of the water meter and affect normal water supply. The anti-freeze measures adopted for this purpose include the following: one is to enclose a layer of insulation material outside the water pipe or water meter, and the other is to open the faucet at home and maintain the trickle state. These two methods are not ideal and they waste water resources.
Summary of the Invention
The invention aims at the problems existing in the prior art, and provides an anti-freezing device of an intelligent water meter, which solves the problem that the existing water meter is susceptible to freezing in the winter.
The figure is a schematic view of the three-dimensional structure
The technical solution adopted by the present invention is as follows: An intelligent water meter anti-freezing device includes a water inlet pipe, a water outlet pipe, and a water meter body. The water inlet pipe and the water outlet pipe are disposed on the left and right sides of the water meter body, and the outermost layer of the water inlet pipe is internally vacuumed. The double-layer vacuum tube and the double-walled vacuum tube have an electric heater plate on the inner surface thereof. The structure of the outlet tube and the inlet tube is the same. The body of the water meter includes a vacuum shell, a dial and a cover, and an electric wire is applied on the inner wall of the vacuum shell. The dial is embedded on the top of the evacuated shell and the cover is connected to the top of the evacuated shell through a rotating shaft. The water meter body is provided with a temperature controller, a central controller and a temperature sensor. The temperature controller is electrically connected to the electric heating sheet and the electric heating respectively. In the wire, the central controller is electrically connected to the temperature sensor, the temperature controller, the electric heating sheet and the heating wire, and a solar power supply device is installed on the body of the water meter. The solar power supply device is electrically connected to the central controller, the temperature sensor and the temperature controller respectively. , electric heating sheet and electric heating wire; Solar power supply device adopts flexible solar panel; cover Inlaid with the center window may be a transparent resin; resin may be a transparent window to evacuate the inside of the vacuum double-layered structure; meter and meter cover body is provided with a mechanical lock engaged with each other; uniformly disposed within the vacuum envelope evacuated reinforcing rib.
The beneficial effects of the present invention are: when the temperature sensor in the water meter body of the present invention detects that the temperature is too low and reaches a preset threshold, the temperature sensor uploads the collected low temperature signal to the central controller, and the central controller receives the low temperature. After the signal, the thermal resistance wire and the electric heating sheet placed on the inner surface of the water meter body, the inlet pipe and the outlet pipe are activated to heat the water passing through the water meter, and the temperature of the heating is controlled by the temperature controller. In this way, the water meter is set. It will not be cracked in the winter; the shell of the water meter body is a vacuum shell, and the outermost layer structure of the water inlet pipe and the outlet pipe is also a double vacuum tube, so that the setting is conducive to maintaining the internal water temperature; and the window level can be The internal vacuum double layer structure further insulates the water in the watch; at the same time, the solar power supply device has the characteristics of environmental protection and energy conservation.
