Self-driven temperature measuring device based on pipeline fluid power generation

Abstract

The invention relates to a self-driven temperature measuring device based on pipeline fluid power generation. The device comprises a water wheel, a miniature generator, a rectifying and voltage stabilizing system, a temperature measuring system and a temperature measuring probe. The water wheel is arranged in a pipe to be measured, a round hole is formed in the pipe, and a water wheel shaft passesthrough the round hole to be connected with the miniature generator outside the pipe. The output end of the miniature generator is connected with the rectifying and voltage stabilizing system, and the output end of the rectifying and voltage stabilizing system is connected with the temperature measuring system. The temperature measuring probe is induced by the temperature measuring system and placed at a measuring point. The temperature measuring system comprises a time control switch, a temperature measuring circuit, a display screen or a wireless data transfer module. The temperature measuring circuit is in parallel connection with two ends of a battery. The device is additionally equipped with a fluid power generation system, the water wheel can collect kinetic energy of fluid in a pipeline to drive the miniature generator to rotate, and the kinetic energy is converted into electric energy, undergoes voltage stabilization through rectifying and then becomes constant direct currents, so energy is provided to the temperature measuring system to measure temperature. Moreover, temperature data can be displayed in real time and can be transmitted from a long distance.

[0002] Nowadays, pipelines are widely used in production and life. In a large number of pipelines, the fluid has a large dynamic potential energy, but these potential energies have not been well utilized, resulting in a waste of resources.

At the same time, in some fields, the measurement of the temperature of the fluid in the pipeline is very important. In the patent with the notification number CN202853793U, a device for measuring the temperature of the fluid in the pipeline is provided. This device uses a water-stop and heat-insulating ring to ensure the stability of the temperature measurement environment , insert a digital temperature sensor into the tee for temperature measurement, and use wireless technology to export the data, but this device needs external energy to work, and is not suitable for some pipelines with complex terrain and inconvenient erection of power supply lines. If necessary, use It will consume a large amount of batteries to power this device, which increases the pollution of waste batteries to the environment.

In the patent No. ZL201720949083, a system that uses pipeline fluid to drive power generation is given. This system uses the fluid in the pipeline to generate power. However, this system has no voltage stabilization function. The temperature measuring device works under a stable DC voltage, and it is easy to burn out the temperature measuring device
