Description

Technical Field

[0001] The present invention relates to the technical field of water meters, and in particular to an antifreeze Internet of Things water meter. Background Art

[0002] A water meter is an instrument that measures the accumulated flow of water. It is generally divided into two categories: volumetric water meters and velocity water meters. Traditional water meters include a shell, a sleeve, and an inner core. After water enters the water inlet, it passes through the lower space of the shell and enters the sleeve. There is a filter at the bottom of the sleeve to filter out debris in the water. Above the lower space, the sleeve is connected to an upper space, which is connected to the water outlet.

[0003] With the gradual development of Internet of Things technology, traditional mechanical water meters and manual meter reading have been gradually replaced by Internet of Things water meters and automatic meter reading with wireless remote information transmission. Internet of Things water meters use microelectronics technology, sensor technology, etc. to measure water volume, and use wireless transmission modules to transmit metering data. The use of Internet of Things water meters provides convenience for control and monitoring, greatly improving the work efficiency of water companies.

[0004] Compared with traditional water meters, IoT water meters are more convenient to use, but their construction costs are often higher than traditional water meters. With the arrival of the cold winter season, outdoor water meters are facing severe climate tests. It is necessary to strengthen anti-freeze measures for IoT water meters to prevent the water flow temperature from affecting the water meter measurement or freezing and cracking to cause damage, so as to save manpower and material costs. Most traditional IoT water meters lack anti-freeze measures and are difficult to meet the needs, and need further improvement. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an antifreeze Internet of Things water meter, which solves the problem that traditional Internet of Things water meters lack antifreeze measures.

[0007] (II) Technical solution

[0008] In order to achieve the above object, the main technical solutions adopted by the present invention include:

[0009] An antifreeze Internet of Things water meter, comprising a counting mechanism component located at the top, a metering mechanism component connected to the bottom of the counting mechanism component, a water meter housing sleeved on the outside of the metering mechanism component, a communication device connected to one side of the counting mechanism component, and a power supply component, characterized in that: the Internet of Things water meter also includes a temperature control device arranged at the bottom of the water meter housing; the temperature control device is communicatively connected to the communication device;

[0010] Wherein, the counting mechanism component is provided with a Bluetooth module which is communicatively connected with the communication device;

[0011] The temperature control device comprises a temperature control device housing, a temperature sensing module and a heating element located inside the temperature control device housing; the temperature sensing module is arranged in contact with the bottom of the water meter housing and is used to detect the temperature of water flowing through the water meter housing;

[0012] When the water flow temperature is lower than a preset value, the heating element is turned on to heat the water flow.

[0013] The temperature control device also includes a water level sensing device, which is embedded in the water meter housing and connected to the heating element. When the water level sensing device detects that there is no water inside the water meter housing, the water level sensing device turns off the heating element to avoid dry burning.

[0014] The interior of the water meter housing is divided into a lower space connected to the water inlet and an upper space connected to the water outlet. The filter sleeve is connected to the upper space and the lower space to filter the water flowing through the lower space and the upper space in sequence.

[0015] The filter sleeve is a multi-layer filter structure, which includes a filter screen, a fiber filter membrane, a medical stone layer, an activated carbon layer and an activated calcium layer; the inner surface and the outer surface of the filter sleeve are the filter screen, and the fiber filter membrane, the medical stone layer, the activated carbon layer and the activated calcium layer are arranged in sequence between the two layers of the filter screen.

[0016] The metering mechanism assembly is located in the upper space of the water meter housing to measure the amount of water flowing through the upper space;

[0017] The metering mechanism component includes a partition, a movement gear and an impeller; the metering mechanism component is electrically connected to the counting mechanism component to provide water volume information to the counting mechanism component.

[0018] The temperature control device is also provided with a temperature control button outside; the temperature control device is also provided with an automatic power-off protection measure in case of water contact.

[0019] The counting mechanism assembly also includes a calculator, a dial, a meter head housing, a meter head upper cover and an upper cover rebound device. The calculator is connected to the dial to enable the dial to display the calculated metering reading.

[0020] The temperature control method of the Internet of Things water meter comprises:

[0021] The IoT water meter is remotely communicated with the control device;

[0022] After determining that water flows through the water meter, the control device sends a first execution instruction to the temperature sensing module to detect the water flow temperature;

[0023] The control device receives the temperature information of the water flow sent by the temperature sensing module in real time;

[0024] The control device compares the temperature information with the preset minimum value. If the water flow temperature of the temperature information is lower than the preset minimum value,

[0025] The control device sends a second execution instruction to the heating element to start working so as to heat the water flow.

[0026] When the heating element heats the water flow to a preset maximum value, the control device sends a third execution instruction to the heating element to turn off the heating element;

[0027] If the water level sensing device detects that there is no water flow in the water meter housing, the heating element is forced to be turned off. At this time, the first execution instruction is entered again.

[0028] (III) Beneficial effects

[0029] The beneficial effects of the present invention are as follows: the antifreeze Internet of Things water meter provided by the present invention is different from the traditional Internet of Things water meter and is provided with a temperature control device to achieve the antifreeze effect in winter, so as to avoid the influence of the outdoor water flow temperature being too low on the measurement of the water meter. The temperature control device is also provided with a water level sensing device to prevent the temperature control device from drying out when the water supply is cut off, so as to achieve the effect of saving resources. The communication device and the counting mechanism component of the Internet of Things water meter are connected by Bluetooth communication. When the communication device is not needed, it can be disassembled separately and used as an ordinary mechanical water meter without affecting other devices and components. Part of the components can be disassembled to achieve the desired purpose of use to the greatest extent without replacing the entire water meter and without damaging the appearance of the water meter.
