Description

Technical Field

[0001] The utility model relates to the field of monitoring instruments, in particular to an intelligent fire hydrant monitoring instrument. Background Art

[0002] Fire hydrants are crucial ancillary facilities in urban water supply networks and essential equipment for fire rescue. However, fire hydrants are often numerous, scattered, easily damaged, difficult to maintain, and complex to manage. Furthermore, they are subject to leakage, illegal water use, and water theft at construction sites, leading to increased water loss and production-sales discrepancies within the network and unclear settlement procedures for municipal landscaping departments. According to the "Code for Fire Protection Design of Buildings," outdoor fire hydrants should be spaced no more than 120 meters apart, with a service area of 150 meters. Based on these standards, tens of thousands of fire hydrants are installed on urban roads. As cities continue to expand, the area covered by fire hydrants is also expanding. Comprehensive, real-time monitoring and management of fire hydrants has become a pressing requirement for fire departments and water supply agencies. However, existing solutions lack functions such as water metering, pressure monitoring, temperature monitoring, and leak monitoring in the main body of the fire hydrant device, making fire hydrant management difficult and increasing labor costs for monitoring. Utility Model Content

[0003] The embodiment of the present application solves the technical problem that the main body of the fire hydrant device in the existing technical solution lacks functions such as water consumption metering, pressure monitoring, temperature monitoring and water leakage monitoring by providing an intelligent fire hydrant monitoring instrument, which makes the management of fire hydrants difficult and increases the cost of human monitoring.

[0004] The technical solutions adopted in the embodiments of this application are as follows:

[0005] A fire hydrant intelligent monitoring instrument includes a circular pipe section, a protective shell, an ultrasonic sensor, a pressure and temperature sensor, an integrated control circuit board and a lithium battery power supply; the circular pipe section is mounted on the inner wall of the protective shell; the integrated control circuit board and the lithium battery power supply are both mounted at the top of the inner cavity of the protective shell; the lithium battery power supply is electrically connected to the integrated control circuit board; the ultrasonic sensor and the pressure and temperature sensor are mounted on the wall of the circular pipe section; the ultrasonic sensor and the pressure and temperature sensor are both electrically connected to the integrated control circuit board via signal lines.

[0006] A further technical solution is: a tilt gyroscope, an Internet of Things card and a microprocessor chip are mounted on the integrated control circuit board.

[0007] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0008] 1. Due to the adoption of the settings of a circular pipe section, a protective housing, an ultrasonic sensor, a pressure and temperature sensor, an integrated control circuit board, and a lithium battery power supply, it can meet the daily management needs of fire hydrants. By clamping a fire hydrant intelligent monitor on the fire hydrant body, after processing and calculating the information collected by the fire hydrant intelligent monitor, it is transmitted to the supporting fire hydrant management information system platform. Then, the water consumption of the fire hydrant can be measured, and the pressure can be collected. It can immediately distinguish whether there is water in the fire hydrant, ensuring that the fire hydrant is always in a complete state with water available. The temperature monitoring function can not only observe and collect the current water supply temperature but also send an early warning to notify the management unit to take anti-freezing measures before the arrival of low-temperature freezing, further ensuring that the fire hydrant is in good condition. This device has a leakage alarm function. After a leakage occurs, such as when the valve of the fire hydrant device is not tightly closed, the device will provide the management unit with leakage information at specific points, helping the management unit to control it in a timely manner and achieving water conservation without waste. The tilt alarm function can trigger the tilt alarm after the device is impacted by an external force and the angle deviates, promptly notifying the management unit to conduct on-site inspections to avoid the expansion of losses or risks.

[0012] By providing a fire hydrant intelligent monitor in an embodiment of the present application, the technical problems in the prior art solution that the main body part of the fire hydrant device lacks functions such as water consumption measurement, pressure monitoring, temperature monitoring, and leakage monitoring are solved. This leads to great difficulty in fire hydrant management and an increase in human monitoring costs.

[0013] The overall idea of the technical solution in the embodiment of the present application to solve the above problems is as follows:

[0014] To better understand the above technical solution, the above technical solution will be described in detail below in combination with the drawings in the specification and specific embodiments.

[0015] A fire hydrant intelligent monitor, as Figure 1 and Figure 2As shown in the figure, it includes a circular pipe section 1, a protective housing 2, an ultrasonic sensor 3, a pressure and temperature sensor 4, an integrated control circuit board 5, and a lithium battery power supply 6; the circular pipe section 1 is installed on the inner wall of the protective housing 2; the integrated control circuit board 5 and the lithium battery power supply 6 are both installed at the top of the inner cavity of the protective housing 2; the lithium battery power supply 6 is electrically connected to the integrated control circuit board 5; the ultrasonic sensor 3 and the pressure and temperature sensor 4 are installed on the wall of the circular pipe section 1; the ultrasonic sensor 3 and the pressure and temperature sensor 4 are both electrically connected to the integrated control circuit board 5 through signal lines.

[0016] An inclinometer, an IoT card, and a microprocessor chip are surface-mounted on the integrated control circuit board 5.

[0017] The computing chip on the integrated control circuit board 5 calculates the current water flow velocity in the pipeline by collecting ultrasonic waves, and then calculates the water flow rate passing through the monitor by combining the time difference method. The pressure and temperature sensor 4 transmits the collected current signal to the integrated control circuit board 5, and the voltage and temperature are collected. An inclinometer, an IoT card, and a microprocessor chip are surface-mounted on the integrated control circuit board 5. Through the preset control logic, abnormalities such as low pressure, high pressure, and temperature below a certain temperature value in the case of non-permitted water intake hydrants are reported to the management unit. It is of great guiding significance for the hydrant management unit to keep the hydrant equipment in good condition and available for water use, prevent low-temperature damage, and prevent low-pressure water shortage.

[0018] Due to the setting of the circular pipe section 1, the protective housing 2, the ultrasonic sensor 3, the pressure and temperature sensor 4, the integrated control circuit board 5, and the lithium battery power supply 6, it can solve the daily management needs of hydrants. By clamping a hydrant intelligent monitor on the hydrant body, after processing and calculating the information collected by the hydrant intelligent monitor, it is transmitted to the supporting hydrant management information system platform. Then, the water consumption of the hydrant can be measured and the pressure can be collected. It can immediately determine whether the hydrant has water, ensuring that the hydrant is always in a complete state with water available. The temperature monitoring function can not only observe and collect the current water supply temperature, but also send an early warning to the management unit before the arrival of low-temperature freezing to do a good job in anti-freezing treatment, further ensuring the good condition of the hydrant. This device has a leakage alarm function. After a leakage occurs, such as when the valve of the hydrant equipment is not tightly closed, the device will provide the management unit with the leakage information at the specific point, helping the management unit to control it in time and achieve water conservation without waste. The tilt alarm function can trigger the tilt alarm after the device is hit by an external force and the angle is offset, and notify the management unit in time to conduct on-site inspections to avoid the expansion of losses or risks.

Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model is also intended to include these modifications and variations.
