[0047] Please refer to Figures 1 to 6, this embodiment provides an intelligent blanking cover 1 for the upgrade and transformation of fire hydrants, including a cover main body 10 for hermetically and detachably connecting with the water outlet of the fire hydrant. An airtight housing 11 is provided on the inner surface of the cover main body 10. A main control module, a communication module, a power supply module, and a water flow sensor that are electrically connected to the main control module are provided in the housing 11. A first through hole 13 is provided on the inner bottom surface of the housing 11. The probe 20 of the water flow sensor penetrates through the first through hole 13, and a seal is provided at the contact position between the probe 20 and the first through hole 13. A gap 30 is provided between the outer wall surface of the housing 11 and the inner edge of the cover main body 10, and the gap 30 is larger than the wall thickness of the water outlet of the fire hydrant. The connection method between the cover main body 10 and the water outlet of the fire hydrant is generally a threaded connection, that is, an external thread is provided on the outer wall of the water outlet of the fire hydrant, and an internal thread is provided on the inner edge of the cover main body 10, so as to threadedly connect the cover main body 10 with the water outlet of the fire hydrant; or a connection method of matching a positioning plate and a positioning pin can be adopted. Specifically, a plurality of positioning holes are provided on the positioning plate, and a limiting hole is provided at the end of the fire pipe body. An inlet is provided at the bottom of the fire hydrant body, and a control lever is screwed on the top. A rotary handle is fixedly connected to the top end of the control lever, and a valve body is fixedly connected to the bottom end. A plurality of mounting holes are provided at the edge of the water outlet, and the positioning pins are sleeved in these mounting holes one by one. The positioning plate covers the water outlet, and one end of the positioning pin is connected to the bottom of the mounting hole through a spring. When the fire pipe body is docked with the water outlet, the positioning pin enters the positioning hole, and through the elastic action of the spring, a reliable connection between the fire pipe and the water outlet of the fire hydrant is achieved. The sealing method between the cover main body 10 and the water outlet of the fire hydrant can adopt an elastic waterproof material to seal the interface, such as rubber or silica gel, and a rubber ring or a rubber gasket can be provided at the connection between the cover main body 10 and the water outlet of the fire hydrant.

[0048] The main control module may include an MCU microcontroller, and the specific model is STM32L151RCT6. The main control module is arranged on a circuit board, and the communication module, the power supply module, and the water flow sensor can all be electrically connected to the main control module through the circuit board.

[0049] The communication module can adopt a wireless communication scheme, such as a Wi-Fi module, a Bluetooth module, a Zigbee module, or can also adopt an NB-IOT communication method for communication.

[0050] The power supply module can be mains power or a storage battery. When mains power is connected, a power supply conversion device needs to be cooperated. Since the power consumption of each electrical appliance used is relatively low, considering the cost of pulling electricity, a storage battery can be used for power supply, such as a 3.6V lithium thionyl chloride battery, which greatly reduces the cost.

[0051] The water flow sensor is provided with water flow probes 20. The number of the first through holes 13 matches the number of the probes 20. Generally, the number of the water flow probes 20 is two, so the number of the first through holes 13 is also two accordingly. The seal can be a waterproof connector or a waterproof sealing ring. Specifically, the water flow sensor determines the state of the water flow by placing the probes 20 inside the fire hydrant and short-circuiting two probes when the water flow passes through. The water flow sensor detects the change of the water flow, transmits the detected signal to the main control module. After signal analysis and conversion by the main control module, water flow data is obtained, and finally, it is transmitted to the upper management platform through the communication module.

[0052] The present invention includes a cover body 10 for hermetically and detachably connecting with the water outlet of the fire hydrant. The inner surface of the cover body 10 is provided with a sealed housing 11. A main control module, a communication module, a power supply module, and a water flow sensor electrically connected to the main control module are arranged inside the housing 11. A first through hole 13 is provided on the inner bottom surface of the housing 11. The probes 20 of the water flow sensor penetrate through the first through hole 13, and a seal is provided at the contact position between the probes 20 and the first through hole 13. By replacing the traditional blank cap with the intelligent blank cap 1, the upgrade transformation of the traditional fire hydrant is realized, so that the distribution points and water flow conditions of the fire hydrants can be fed back to the upper management platform in real time, which is convenient for supervision and easy to transform. Compared with the whole replacement, it has a greater cost advantage.

[0053] In some embodiments, it further includes a tilt sensor, which is disposed inside the housing 11 and electrically connected to the main control module. The tilt sensor triggers a signal by detecting the tilt angle of an object. Inside the tilt sensor, there is a mass that can move freely, usually a rolling ball, and there is a conductive plate below it. When the sensor is completely upright, the ball falls to the bottom of the sensor, contacts the electrical connection path, closes the electrical connection of the two terminal ends, and enables current to flow. When the sensor tilts, the ball does not fall to the bottom and close the conductive path, resulting in an open conductive path and no current flowing. Specifically for the tilt sensor of a fire hydrant, its function is to immediately send an alarm signal when the fire hydrant is impacted or tilted beyond a certain angle. The tilt sensor is placed on the fire hydrant and remains vertical with the fire hydrant in the normal state. When the fire hydrant tilts, it drives the tilt sensor to tilt. The tilt sensor generates an electrical signal and transmits it to the main control module. After analyzing the electrical signal, the main control module obtains the tilt angle and sends the alarm information to the upper management platform through the communication module to notify the repair personnel to react quickly and arrive at the scene in time to check and verify the situation. This effectively improves the management efficiency and safety of fire hydrants and reduces potential safety hazards caused by damaged or stolen fire hydrants. The model of the tilt sensor can refer to T60404-E4626-X121, BWK210, or BWM426, etc. Preferably, the tilt sensor can adopt the ADXL345 three-axis chip. The ADXL345 is a small and thin low-power three-axis accelerometer that can perform high-resolution (13-bit) measurements of accelerations up to ±16g. By setting a tilt sensor inside the blind cover, the tilt state of the fire hydrant can be monitored in real time to ensure its stability and safety.

[0054] In some embodiments, the cover body 10 is provided with a second through hole 101 communicating with the housing 11, and a key 40 is provided at the second through hole 101. The key 40 is electrically connected to the main control module. By presetting the main control module and the communication module, the key is configured as an alarm mapping key. When a fire hazard occurs, the fire location can be quickly located through one-key alarm, realizing the one-key alarm function of the fire hydrant. The various functions of the main control module can also be controlled through the key 40, such as starting by single-clicking, closing by long-pressing, and other functions.

[0055] In some embodiments, a convex portion 50 is provided at the center of the outer surface of the cover body 10. At least a pair of planes are symmetrically provided on the side surface of the convex portion 50. A third through hole 51 is provided at the center of the convex portion 50. The third through hole 51 is internally communicated with the inside of the housing 11 through the second through hole 101. In this embodiment, the button 40 can also be substantially at the third through hole 51. The connecting line between the button 40 and the main control module can sequentially pass through the second through hole 101 and the third through hole 51. The convex portion 50 is used for connecting and rotating with a valve opening tool. The convex portion 50 can be a regular hexagonal prism structure, which is convenient for the valve opening tool to connect with it from any angle.

[0056] In some embodiments, the housing 11 is composed of a housing cover 111 and a housing cylinder 112. One end of the housing cylinder 112 is fixedly connected to the inner surface of the cover body 10, and the other end is hermetically and detachably connected to the housing cover 111. The housing cover 111 and the housing cylinder 112 can adopt connection methods such as snap connection and sliding connection. Preferably, in order to improve the connection stability between the housing cover 111 and the housing cylinder 112, a fastener can be used for fastening connection, and the connection part between the two can be sealed with an elastic waterproof material, such as rubber or silicone, to ensure airtightness. By setting the housing 11 in a split structure, it is convenient for assembly, installation, and subsequent maintenance and repair work.

[0057] Since using a fastener connection requires drilling holes in the housing cylinder 112, if a large-sized bolt is used to provide connection stability, a larger screw hole needs to be opened in the housing cylinder 112, which means that the wall thickness of the housing cylinder 112 needs to be increased. When the wall thickness of the housing cylinder 112 increases, the internal space decreases, affecting the layout of internal electronic devices. Therefore, in some embodiments, a plurality of structural ribs 1121 are provided on the inner wall surface of the housing cylinder 112, and connection holes 1122 are provided at the positions where the structural ribs 1121 are located. A plurality of fourth through holes 1111 corresponding to the connection holes 1122 one by one are provided on the housing cover 111. Through this structure, while ensuring the connection stability between the housing cover 111 and the housing cylinder 112, the loss of the internal space of the housing 11 can be minimized as much as possible, which is convenient for arranging more electronic devices and realizing more functions.

[0058] In some embodiments, the power supply module uses an alkaline battery, such as a No. 2 battery. A battery slot 1112 is provided on the inner surface of the housing cover 111. The accommodating space of the battery slot 1112 is adapted to the shape of the battery. By embedding the battery into the battery slot 1112, it is stably fixed on the housing cover 111, improving the utilization rate of the internal space of the housing 11.

[0059] In some embodiments, fixing columns 1113 are provided on the inner surface of the shell cover 111. There are multiple fixing columns 1113, and the space enclosed by the multiple fixing columns 1113 is adapted to the main control module. The main control module is fixedly installed through the fixing columns 1113 to improve the stability of the main control module.

[0060] The novel intelligent blanking cover is developed based on technologies such as the Internet of Things, cloud technology, and big data, and includes two parts: a remote Internet of Things monitoring device and an intelligent fire hydrant integrated management platform. The remote Internet of Things monitoring device consists of an Internet of Things main control board, a lithium thionyl chloride battery, an inclination sensor, a water flow sensor, and a packaging shell. Among them, the Internet of Things main control board is powered by a lithium battery and communicates using the NB-IOT communication method. The Internet of Things main control board monitors the water flow sensor in real time and periodically monitors the working parameters of the inclination sensor. When the working parameters of the relevant sensors exceed the preset threshold, the device actively reports alarm information to the intelligent fire hydrant integrated management platform.

[0061] The intelligent fire hydrant integrated management platform is deployed in the form of a cloud platform. The platform includes a PC-side management platform, an APP, and a WeChat official account. Among them, the functions of the PC-side management platform include function modules such as a home page, user management, device management, alarm query, work order management, report center, and digital large screen. Through the PC-side management platform, the data reported by the remote Internet of Things monitoring module is comprehensively summarized, displayed, and managed. At the same time, the relevant parameters of the device can be remotely set through the management platform.

[0062] The WeChat official account platform includes function modules such as device management, alarm query, map display, work order management, and mine. Through the mobile phone, the device status of the remote Internet of Things monitoring device can be viewed and the alarm can be queried. At the same time, the device installation can be realized through the WeChat official account when the device is initially installed.

[0063] The novel intelligent blanking cover is used to upgrade traditional fire hydrants to intelligent fire hydrants. By replacing the original traditional blanking cover with an intelligent blanking cover and then supporting the corresponding intelligent fire hydrant integrated management platform, the traditional fire hydrant can be upgraded to an intelligent fire hydrant. The functions of the intelligent blanking cover include: water outlet monitoring, inclination monitoring, remaining water monitoring, positioning and navigation, battery voltage monitoring, signal strength monitoring, etc.

[0064] It should be noted that although the above-mentioned embodiments have been described in this article, the patent protection scope of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, any changes and modifications made to the embodiments described in this article, or equivalent structural or equivalent process transformations made using the content of the specification and drawings of the present invention, and directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present invention.
