Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, and more specifically to an intelligent saddle-type water flow indicator. Background Art

[0002] In fire protection systems, water flow indicators are key devices for monitoring water flow status, which are essential for timely detection of fires and taking appropriate fire-fighting measures. Traditional water flow indicators mainly rely on mechanical structures to detect water flow and trigger alarms through mechanical signals. However, this type of mechanical water flow indicator has problems such as slow response speed, low accuracy, and susceptibility to interference from environmental factors.

[0003] With the advancement of science and technology and the application of intelligent technology, fire-fighting equipment is also developing in the direction of intelligence and automation. Intelligent water flow indicators have come into being. By integrating sensors, microprocessors and communication technologies, they can more accurately monitor water flow status and respond quickly. Intelligent water flow indicators can not only improve the accuracy of fire detection, but also realize remote monitoring and alarm functions, greatly improving the efficiency and safety of fire-fighting systems.

[0004] However, the intelligent water flow indicators currently on the market still have some limitations in structural design and functional implementation. For example, some intelligent water flow indicators may be affected by factors such as water flow velocity and water flow direction when sensing water flow, resulting in low detection accuracy. In addition, some intelligent water flow indicators also have deficiencies in alarm methods and remote control and cannot meet the needs of modern fire protection systems. More importantly, when the water flow is too large, the traditional rotating rod indicator is prone to rotate too quickly, causing damage to some parts of the indicator, thereby reducing the reliability and service life of the equipment. Therefore, the utility model aims to provide an improved intelligent saddle-type water flow indicator, which solves the problems existing in the prior art by optimizing the structural design and functional implementation, and improves the accuracy of water flow detection and the reliability of alarm.

[0046] The indicator housing is made of waterproof, dustproof and corrosion-resistant materials to ensure the normal operation of the equipment in harsh environments.

[0047] Working principle:

[0048] This utility model is mainly based on electromagnetic control technology and mechanical transmission principle. When water flows through the pipe, the water flow will push the blade-shaped paddle inside the U-shaped rod, and then drive the rotating rod connected to the blade-shaped paddle to rotate. The rotation speed of the rotating rod reflects the flow rate of the water flow, and the encoder installed on the rotating rod will measure and record the speed data in real time.

[0049] There is an iron block at the top of the rotating rod, and an electromagnet is arranged at the inner top of the indicator through an elastic member, which is opposite to the iron block. When the electromagnet is energized, a magnetic field is generated to attract the iron block, thereby limiting the rotation of the rotating rod. This electromagnetic control method allows us to accurately adjust the magnetic field strength of the electromagnet, thereby controlling the attraction to the iron block and realizing the limitation and adjustment of the rotation speed of the rotating rod.

[0050] As the core of the entire system, the central control module will receive the rotating rod speed data from the encoder in real time. According to the preset conditions and logic, the central control module will control the on and off state of the electromagnet and the current size, thereby realizing precise control and regulation of the water flow rate. At the same time, when the water flow state is abnormal (such as too fast flow rate, too slow flow rate or stop flow, etc.), the central control module will trigger the alarm module and send out sound and light alarm signals to alert the staff.

[0051] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0052] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
