Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, and more specifically to a modular Internet of Things fire hydrant head cover. Background Technology

[0002] As a core component of urban fire protection infrastructure, the integrity and reliability of fire hydrants directly affect the success or failure of fire rescue in relevant areas. In this regard, traditional fire hydrant caps generally only serve as physical openings to open fire hydrants and cannot monitor the condition of the fire hydrant itself. As a result, when fire hydrants are damaged, they cannot be detected and dealt with in a timely manner.

[0003] With the development of IoT technology, smart fire hydrant solutions are now available on the market. These solutions integrate specific sensors onto the fire hydrant to achieve status monitoring. However, most of these smart fire hydrants have a fixed function when they leave the factory. This fixed design cannot adapt to the differentiated needs of different usage scenarios (such as temperature monitoring in cold regions, and anti-vandalism monitoring in important areas), and therefore needs to be improved. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a modular IoT fire hydrant cover that enables personalized installation through the connection of sensor modules and installation interfaces to meet different usage requirements.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A modular IoT fire hydrant head cover, comprising: Cover; A battery module, wherein the battery module is housed within a cover; A power supply module is disposed on the upper end of the cover and is electrically connected to the battery module; A communication module is housed within a cover and is electrically connected to a battery module. The communication module is used for wireless communication with an Internet of Things (IoT) platform. The lower end of the cover is provided with multiple mounting interfaces, and the bottom of the mounting interface hole is provided with a first electrical connector, which is electrically connected to the battery module and the communication module respectively. The sensor module has a detachable connection and installation interface at its upper end. The sensor module is provided with a second electrical connector corresponding to the first electrical connector. Data communication between the sensor module and the communication module is realized through the electrical connection between the first electrical connector and the second electrical connector. A plug, used to removably seal the mounting interface where no sensor module is installed.

[0006] As a further improvement of this utility model, the power supply module is a solar panel, and the upper end of the cover is provided with an annular flange. The height of the flange is higher than the upper surface of the solar panel, and the inner diameter of the flange is larger than the outer diameter of the solar panel.

[0007] As a further improvement of this utility model, the first electrical connector includes at least two concentric annular conductive contacts disposed at the bottom of the mounting interface, and the second electrical connector includes spring pins corresponding to the number and position of the concentric annular conductive contacts; when the sensor module is screwed into the mounting interface, the spring pins maintain tight electrical contact with the corresponding concentric annular conductive contacts under axial pressure.

[0008] As a further improvement of this utility model, a limiting surface is provided at the mounting interface, which is used to abut against the sensor module to limit the range of movement of the sensor module relative to the axis of the mounting interface.

[0009] As a further improvement of this utility model, the outer wall of the sensor module is threadedly connected to the mounting hole.

[0010] As a further improvement of this utility model, it also includes an anti-theft unit, which includes a fixing component and a detection component. The fixing component is fixedly connected to the fire hydrant, and the detection component is connected to the cover and moves synchronously with the cover. The detection component is used to detect the relative angular displacement between the detection component and the fixing component, and the detection component is electrically connected to the battery module and the communication module.

[0011] As a further improvement of this utility model, the fixing component is a permanent magnet, and the detection component is a reed switch, which is used to close when close to the permanent magnet and open when away from the permanent magnet.

[0012] The beneficial effects of this utility model are: 1. By setting multiple standardized installation interfaces at the bottom of the main body, and with the addition of pluggable sensor modules and plugs, the problem of the single function of traditional fire hydrant heads is avoided. Operators can flexibly configure different types of sensor modules such as water pressure, flow rate, and temperature as needed, thereby greatly improving the level of precision in fire hydrant management.

[0013] 2. The electrical connection scheme, which combines the threaded connection of the sensor module with the concentric annular conductive contact and the spring pin, ensures the airtight connection between the sensor module and the cover while providing good mechanical connection stability. It also ensures the continuous stability of electrical contact and effectively overcomes vibration and corrosion in harsh outdoor environments.

[0014] 3. By detecting unauthorized relative rotation between the cover and the fire hydrant body through an integrated anti-theft unit, a remote alarm can be issued immediately in the event of theft or vandalism, ensuring the integrity of this critical public fire protection facility.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.

[0018] like Figure 1-5 As shown, a modular IoT fire hydrant head cover includes a cover body 1, a power supply module 3, a battery module 2, a communication module 4, a sensor module 7, and a plug 9.

[0019] Specifically, the cover 1 is supported by corrosion-resistant metal, and the side of the cover 1 forms a threaded section that connects with the fire hydrant. A solar panel is fixedly installed in the central area of ​​the upper end of the cover 1 as an energy supply module 3, so as to achieve continuous function during long-term use. The upper end of the cover 1 is provided with a connecting rod 10 and an annular flange 11 is connected through the connecting rod 10. The height of the flange 11 is higher than the upper surface of the solar panel, and the inner diameter of the flange 11 is larger than the outer circle diameter of the solar panel, so as to protect the solar panel through the flange 11 and avoid interference with the solar panel's light collection.

[0020] Furthermore, the interior of the cover 1 houses a battery module 2 and a communication module 4. The battery module 2 is specifically a rechargeable lithium battery pack, which is electrically connected to a solar panel for charging. The communication module 4 is specifically an NB-IoT communication module, which is electrically connected to the battery module 2 and is used to wirelessly transmit the collected data to a remote IoT cloud platform.

[0021] Furthermore, the lower end face of the cover 1 is provided with four mounting interfaces 5, each mounting interface 5 is a blind hole with internal threads, and the bottom of the hole of each mounting interface 5 is inlaid with a first electrical connector 6. In this embodiment, the first electrical connector 6 is specifically two concentric annular conductive contacts 12. The two concentric annular conductive contacts 12 serve as the positive and negative terminals of the power supply, respectively. The two concentric annular conductive contacts 12 are electrically connected to the battery module 2 and the communication module through an internal circuit.

[0022] Furthermore, in this embodiment, the sensor module 7 includes a housing and an internal detection unit. The outer side of the housing is provided with an external thread that matches the internal thread of the mounting interface 5. A second electrical connector 8 is provided at the center of the top of the housing. The second electrical connector 8 includes two spring pins 13, which correspond to two concentric annular conductive contacts 12 respectively. Thus, when the housing is screwed into the mounting interface 5, the two spring pins 13 maintain tight electrical contact with the corresponding concentric annular conductive contacts 12 under axial pressure.

[0023] Furthermore, at the end of the housing being screwed into the mounting interface 5, the top of the housing will abut against the limiting surface 14 at the bottom of the mounting interface 5, thereby limiting its maximum screwing depth and preventing excessive compression. At the same time, the spring pin 13 of the second electrical connector 8 is compressed under axial pressure, forming a stable and reliable elastic electrical contact with the concentric annular conductive contact 12 of the first electrical connector 6, thereby powering the sensor module 7 and establishing a data communication link.

[0024] Specifically, the different sensor modules 7 correspond to different internal detection units to achieve different detection functions. The detection unit includes a pressure sensing chip, an ultrasonic flow meter, and a temperature sensor, which are used to detect the pressure, water flow, and temperature inside the fire hydrant, respectively, to meet different usage requirements.

[0025] For the mounting interface 5 where the sensor module 7 is not installed, a plug 9 is used to seal it. The upper part of the plug 9 has a threaded area and is threaded to the mounting interface 5. The top of the plug 9 has a sealing ring to ensure that when it is tightened, it can effectively prevent moisture and dust from entering the inside of the cover 1 from the interface, thus ensuring the overall IP protection level.

[0026] Furthermore, it also includes an anti-theft unit 15, which includes a fixing component 16 and a detection component 17. The fixing component 16 is fixedly connected to the fire hydrant, and the detection component 17 is connected to the cover 1 and moves synchronously with the cover 1. The detection component 17 is used to detect the relative angular displacement between the detection component 17 and the fixing component 16. The detection component 17 is electrically connected to the battery module 2 and the communication module 4.

[0027] Specifically, the fixing component 16 is a permanent magnet, and the detection component 17 is a reed switch. The reed switch is used to close when it is close to the permanent magnet and to open when it is far away from the permanent magnet. The reed switch is set at the lower end of the cover 1 and is offset relative to the axis of the cover 1, so that the position of the reed switch relative to the permanent magnet can be adjusted when the cover 1 rotates.

[0028] When the cover 1 is tightened properly, the reed switch is close to the permanent magnet, and both are within a preset safety detection range. At this time, the reed switch closes under the action of the permanent magnet. When the cover 1 rotates more than the preset value relative to the fire hydrant, the position of the reed switch relative to the permanent magnet shifts, causing the reed switch to open. The communication module 4 receives the reed switch signal and sends an alarm message through the communication module 4 to achieve the anti-theft function.

[0029] Furthermore, different types of sensor modules 7 each have a pre-set identification code. When the sensor module 7 is connected to the cover 1, the communication module 4 can read the identification code to identify the type of sensor connected, thereby automatically loading the corresponding driver and data parsing algorithm to perform corresponding data acquisition and make the sensor module 7 plug-and-play.

[0030] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
