Detailed Implementation

[0020] With the development of intelligent firefighting equipment, firefighting robots have made significant progress in many aspects, such as being able to autonomously connect to fire pipelines and enter hazardous areas to perform tasks. However, the practical application of firefighting robots often relies on the supporting intelligent fire hydrant system. Currently, the vast majority of fire hydrants that have been extensively installed and put into use still rely on manual operation, which greatly limits the automation capabilities of firefighting robots and the overall rescue efficiency.

[0021] Therefore, how to reasonably and feasiblely modify existing manual fire hydrants to enable them to achieve remote control and automatic switching functions has become the key technical problem to be solved in this application.

[0022] To address the aforementioned problems, this invention provides a remote autonomous shut-off device for fire hydrants, which can non-destructively modify existing manual fire hydrants to enable them to be opened and closed remotely, thereby improving the problem that existing fire hydrants cannot be automatically opened and closed.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0028] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0029] The following detailed description of the overall structure, working principle, and technical effects of the fire hydrant remote autonomous shut-off device provided by the present invention, through embodiments and in conjunction with the accompanying drawings, is a practical example.

[0030] Please refer to Figure 1 This embodiment provides a remote autonomous shut-off device 100 for fire hydrants. This device can non-destructively modify existing manual fire hydrants 200 to enable them to have remote control and automatic opening and closing functions, so as to be used in conjunction with intelligent fire protection systems, thereby effectively reducing the cost of intelligent transformation of fire protection facilities.

[0031] Please refer to Figures 1 to 8 In this embodiment, the fire hydrant remote autonomous shut-off device 100 includes a drive box 110, an adapter sleeve 120, a first connecting ring 130, a second connecting ring 140, and a third connecting ring 150. The drive box 110 houses a motor 111, a power supply 112, and a main control board 113. The power supply 112 is connected to the main control board 113, which is connected to the motor 111. The main control board 113 can communicate with a terminal device to receive and execute commands to control the motor 111. The adapter sleeve 120 extends from the drive box 110 and is connected to the motor 111 for engagement with the valve stem 210 at the top of the fire hydrant 200, thereby driving the valve stem 210 to rotate. The first connecting ring 130 and the second connecting ring 140 are respectively connected to opposite sides of the drive box 110. One end of the third connecting ring 150 is connected to the first connecting ring 130, and the other end is connected to the second connecting ring 140. After the drive box 110 is installed on the top of the fire hydrant 200 and the adapter sleeve 120 is engaged with the valve stem 210, the two sides of the third connecting pull ring 150 can be wrapped around to the bottom of the two opposite water outlets 230 of the fire hydrant 200, thereby firmly fixing the drive box 110 to the top of the fire hydrant 200.

[0032] Specifically, this embodiment achieves non-destructive installation through a fixing system consisting of a first connecting pull ring 130, a second connecting pull ring 140, and a third connecting pull ring 150. During assembly, the first connecting pull ring 130 and the second connecting pull ring 140 are first installed on both sides of the drive box 110. Then, the drive box 110 is placed on top of the fire hydrant 200, ensuring precise engagement between the adapter sleeve 120 and the valve stem 210 of the fire hydrant 200. Next, the third connecting pull ring 150 is wound around to below the two opposite water outlets 230 of the fire hydrant 200, and its two ends are connected to and locked to the first connecting pull ring 130 and the second connecting pull ring 140, respectively. Through the constraint and tension forces generated by the pull ring system, the drive box 110 is firmly pressed and fixed to the fire hydrant 200. The entire installation process requires no drilling or welding of the fire hydrant 200 body. The motor 111 inside the drive box 110 drives the adapter sleeve 120 to rotate through the transmission mechanism, which in turn drives the valve stem 210 of the fire hydrant 200 to rotate, thereby opening or closing the valve. The main control board 113 is responsible for processing wireless commands from the terminal device, controlling the operation of the motor 111, and finally completing the remote control of the fire hydrant 200.

[0033] It should be noted that a typical outdoor fire hydrant 200 usually includes a hydrant body 220, a valve stem 210 vertically installed at the top of the hydrant body 220, and a water outlet 230 located on the side of the hydrant body 220 for connecting a fire hose. Generally, a fire hydrant 200 has three water outlets 230: one located on the front side of the hydrant body 220, and the other two symmetrically arranged on the left and right sides of the hydrant body 220.

[0034] The core advantage of this embodiment lies in its non-destructive installation characteristics. Its fixing mechanism cleverly utilizes the water outlet 230, which has the highest structural strength on the fire hydrant 200 body, as the main load-bearing point. The third connecting ring 150 holds the two opposing water outlets 230 from below, and the first connecting ring 130 and the second connecting ring 140 pull the drive box 110 downwards, effectively transferring the weight and working reaction force of the drive box 110 to the top of the hydrant body 220.

[0035] The adapter sleeve 120 is fitted onto the valve stem 210 of the fire hydrant 200, with the adapter sleeve 120 fitting onto the end of the valve stem 210 to ensure effective torque transmission. The power supply 112 typically uses a rechargeable battery pack. The main control board 113 integrates a microprocessor, a motor 111 drive circuit, and a wireless communication module (such as 4G / 5G, NB-IoT, etc.), enabling communication with monitoring centers, mobile terminals, or intelligent fire-fighting equipment to receive instructions and report status.

[0036] Please refer to Figures 1 to 8In this embodiment, the drive box 110 includes a box body 114 and a box cover 115. The motor 111, power supply 112, and main control board 113 are installed inside the box body 114, and the box cover 115 is sealed to the box body 114 by fasteners. The top two opposite edges of the box cover 115 are provided with upward-opening snap-fit ​​grooves 116. The first connecting pull ring 130 and the second connecting pull ring 140 are both U-shaped, with their top horizontal bars respectively hanging in the snap-fit ​​grooves 116 on both sides of the box cover 115, and their vertical bars extending downwards to the bottom area of ​​the box body 114. The third connecting pull ring 150 has two oppositely arranged V-shaped snap-fit ​​parts 151, which can be snapped into the bottom of the two opposite water outlets 230 of the fire hydrant 200.

[0037] The first connecting pull ring 130 and the second connecting pull ring 140 are designed in a "U" shape, which is simple and reliable in structure and facilitates quick installation through the snap-fit ​​groove 116. After installation, the vertical rod of the pull ring exerts a downward pulling force on the cover 115, which helps to enhance the sealing effect between the cover 115 and the box body 114. The "V"-shaped snap-fit ​​part 151 of the third connecting pull ring 150 is designed so that it can conform to the arc structure at the bottom of the water outlet 230 to achieve a stable snap-fit, and naturally extends to the connection point with the first connecting pull ring 130 and the second connecting pull ring 140.

[0038] Furthermore, the free ends of the two locking parts 151 of the third connecting ring 150 are each provided with a hook 152. The other ends of the two locking parts 151 are connected to a first connecting plate 153. The lower ends of the two vertical rods of the second connecting ring 140 are connected by a second connecting plate 141. The first connecting plate 153 has a first through hole 154, and the second connecting plate 141 has a second through hole 142. During installation, first hook the hooks 152 of the two locking parts 151 onto the horizontal bar or designated hanging point at the lower part of the first connecting ring 130, then align the first connecting plate 153 with the second connecting plate 141, use a locking bolt 156 to pass through the first through hole 154 and the second through hole 142 in sequence, and finally tighten with a nut 157. By tightening the nut 157, the tension of the entire ring system can be adjusted, thereby firmly fixing the drive box 110 to the top of the fire hydrant 200.

[0039] The design allows for quick attachment on one side via hook 152, while the other side is secured with a connecting plate and bolts. This design balances ease of installation with reliable locking and allows for adjustment of the preload force according to the specific dimensions of the fire hydrant 200.

[0040] It is important to emphasize that when installing the drive box 110, its circumferential orientation needs to be adjusted. The two sides of the drive box 110 where the first connecting ring 130 and the second connecting ring 140 are installed (i.e., the two sides with the snap-fit ​​groove 116) should be aligned with the positions of the two corresponding water outlets 230 on the fire hydrant 200, roughly forming a cross shape. In this way, the two "V"-shaped snap-fit ​​parts 151 of the third connecting ring 150 can accurately snap into the bottom of these two water outlets 230.

[0041] Please refer to Figures 1 to 8 In this embodiment, the surfaces of the two snap-fit ​​parts 151 that contact the water outlet interface 230 of the fire hydrant 200 are covered with anti-slip sleeves 155. The anti-slip sleeves 155 can be made of rubber or high-friction coefficient engineering plastics, which can effectively prevent the snap-fit ​​parts 151 from sliding at the bottom of the interface and significantly improve the stability of the installation.

[0042] In this embodiment, on the outer walls of the box body 114 and the box cover 115, at positions corresponding to the two ends of the snap-fit ​​groove 116, there is a longitudinal recessed limiting groove 117. The two vertical rods of the first connecting pull ring 130 and the second connecting pull ring 140 are respectively embedded in the corresponding limiting grooves 117. The function of the limiting grooves 117 is to restrict the sliding of the first connecting pull ring 130 and the second connecting pull ring 140 along the edge of the box cover 115, ensuring that the pull ring positions are fixed and maintaining the symmetry and force balance of the fixing system.

[0043] In this embodiment, an annular sealing ring 118 is embedded between the mating surfaces of the cover 115 and the body 114, and the cover 115 and the body 114 are fastened together by multiple screws 119. The sealing ring 118 can effectively prevent rainwater and dust from entering and protect the internal electronic components; the screw connection 119 ensures the overall rigidity of the structure and the reliability of the connection.

[0044] Please refer to Figures 1 to 8 In this embodiment, the fire hydrant remote autonomous shut-off device 100 further includes a reducer assembly 160 and a worm gear commutator assembly 170. A motor 111 is horizontally mounted within a housing 114. The output shaft of the motor 111 is connected to the reducer assembly 160. The output shaft of the reducer assembly 160 is drive-connected to the worm gear 171 in the worm gear commutator assembly 170. The upper end of the adapter sleeve 120 is drive-connected to the worm gear 172 in the worm gear commutator assembly 170. This transmission system converts the horizontal rotational motion of the motor 111 into the vertical rotational motion required by the adapter sleeve 120, and amplifies the torque.

[0045] The reducer assembly 160 increases the output torque to meet the high torque required to drive the valve stem 210 of the fire hydrant 200. The worm gear commutator assembly 170 achieves a 90-degree change in the power transmission direction, resulting in a reasonable structural layout and facilitating the vertical alignment of the adapter sleeve 120 with the valve stem 210.

[0046] It should be noted that a protrusion hole 121 is opened at the center of the bottom of the housing 114. The worm gear commutator assembly 170 is fixed inside the housing 114, and the adapter sleeve 120 is connected to the output shaft of the worm gear 172 by means of splines or the like, with its lower end extending out of the housing 114 through the protrusion hole 121.

[0047] The reducer assembly 160 includes a reducer housing 161 and an internal reduction gear set 162. A motor 111 is mounted on the reducer housing 161, and its output shaft gear meshes with the input gear of the reduction gear set 162. After multiple stages of reduction, the final output gear drives the worm 171 of the worm gear commutator assembly 170. The worm 171 and worm gear 172 of the worm gear commutator assembly 170 mesh perpendicularly to each other.

[0048] Please refer to Figures 1 to 8 In this embodiment, the fire hydrant remote autonomous shut-off device 100 further includes an annular buffer pad 180. The buffer pad 180 is fitted over the portion of the adapter sleeve 120 extending from the bottom of the housing 114, located between the lower surface of the bottom plate of the housing 114 and the top plane of the fire hydrant 200. The buffer pad 180 is made of elastic material and is used to fill gaps, reduce shaking, assist in sealing, and provide some vibration damping.

[0049] In this embodiment, the fire hydrant remote autonomous shut-off device 100 also includes a solar panel assembly 190. The solar panel assembly 190 is mounted on the outside of the drive box 110 and is used to charge the power supply inside the box under sunlight.

[0050] Adding a solar panel module 190 can provide continuous auxiliary power to the device, extend battery life, reduce maintenance, and is especially suitable for outdoor locations without mains power.

[0051] Specifically, the solar panel assembly 190 includes a solar panel 191, a support bracket 192, and a photovoltaic panel controller 193. There are two support brackets 192, symmetrically mounted on both sides of the drive box 110 housing. The solar panel 191 is fixed to the support bracket 192 at an angle. The photovoltaic panel controller 193 is installed inside the drive box 110 and is connected to both the solar panel 191 and the battery, managing the charging process.

[0052] In this embodiment, a first electrical connection interface 123 and a second electrical connection interface 124 are installed on the side wall of the housing 114. The solar panel 191 is connected to the first electrical connection interface 123 via a connecting cable, and the first electrical connection interface 123 is electrically connected to the photovoltaic panel controller 193. The second electrical connection interface 124 is electrically connected to the battery and can be used as a backup charging interface to connect to an external power source 112.

[0053] Both the first electrical connection interface 123 and the second electrical connection interface 124 use waterproof plug terminals (such as waterproof aviation plugs) to ensure electrical connection while ensuring the sealing of the housing 114.

[0054] Please refer to Figures 1 to 8 In this embodiment, an identification mark is provided on one outer surface of the drive box 110. This mark is used for intelligent fire extinguishing equipment or inspection equipment to automatically identify the number, specifications, and precise location of the outlet of the fire hydrant 200.

[0055] The identification mark can be a QR code, barcode, or an invisible light mark such as an infrared LED connected to power supply 112 and oriented towards a specific point. The accompanying intelligent device uses a vision system to recognize this mark, accurately locating the water outlet and guiding the automatic hose connection.

[0056] The fire hydrant remote autonomous shut-off device 100 can connect to various terminal devices (such as monitoring center computers, mobile apps, and smart wearable devices) via wireless network. It not only supports remote switching but also allows for valve opening adjustment to meet the water pressure and flow requirements of different fire situations. The device has intelligent detection capabilities: when the pipeline pressure is known, it can estimate the cumulative water output based on the valve opening time; it can also provide feedback on pressure and flow data within the fire hose. The main control board 113 can also integrate a positioning module, enabling the platform to view the real-time location of all networked fire hydrants 200.

[0057] This device can work in conjunction with unmanned intelligent firefighting robots to achieve fully automated fire suppression. After detecting a fire, the intelligent fire hydrant planning device will take a route to the nearest fire hydrant 200 equipped with the device, visually identify and mark it using a robotic arm, connect the hose, then proceed to the fire scene and remotely open the fire hydrant 200 to extinguish the fire, and remotely close it after the fire is extinguished.

[0058] In scenarios where firefighters are manually connecting the hose, they can remotely open the fire hydrant 200 via a smart wearable device while en route to the fire scene. Upon arrival, water supply is immediately available, eliminating the need for a dedicated operator to operate the hydrant body 220. The hydrant can be remotely closed after the fire is extinguished, thus improving efficiency.

[0059] This device can also be used to support intelligent inspection. The inspection equipment arrives at the location periodically, remotely sends a brief opening command, checks and records the water output status through a camera, and automatically generates inspection logs and fault alarms, realizing intelligent management of the status of fire hydrants.

[0060] In summary, this embodiment, by setting up a mechanical fixing mechanism consisting of a first connecting pull ring 130, a second connecting pull ring 140, and a third connecting pull ring 150, combined with the motor 111 drive system, intelligent control system, and wireless communication system inside the drive box 110, realizes a remote autonomous shut-off device 100 that is easy to install, reliably fixed, and requires no modification to the fire hydrant 200 itself. This device upgrades the traditional manual fire hydrant 200 into an intelligent fire terminal that can be remotely controlled and has its status monitored, providing an effective technical solution for building a smart fire protection system.

[0061] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
