Description

Technical Field

[0001] This invention relates to the field of fire hydrant technology, specifically to an intelligent digital fire hydrant and monitoring system. Background Art

[0002] Fire hydrants are ancillary facilities of urban water supply networks and important fire control equipment. Their function is to control combustibles, isolate oxidizers, and eliminate ignition sources. Their effectiveness is directly related to people's lives and property safety.

[0003] Chinese Patent CN113893490A discloses an intelligent fire hydrant, a fire hydrant status monitoring system, and a method. The intelligent fire hydrant includes a fixedly connected hydrant body and a valve body. Multiple sensors are fixedly mounted on the hydrant body, and a solar power generation component is fixedly mounted on the valve body. The solar power generation component and all sensors are electrically connected to a data collector. A protective mechanism for protecting the hydrant body is fixedly mounted around its periphery. The protective mechanism includes multiple protective tubes distributed along the circumference of the hydrant body. A deformation monitoring mechanism for monitoring the deformation of the protective tubes is installed within each protective tube. The deformation monitoring mechanism is electrically connected to the data collector. This invention can monitor the status of the fire water inside the fire hydrant and the status of the protective tubes in real time, thereby enabling real-time monitoring of the fire hydrant's operation. Furthermore, when the protective tubes deform, it can promptly notify management personnel to arrive on-site for fire hydrant maintenance, preventing damage to the fire hydrant and waste of fire water.

[0004] The existing fire hydrants have internal monitoring systems to monitor water usage. However, these systems have limited monitoring equipment, resulting in poor monitoring of data such as water pressure identification, warning signals, and flow rate. This leads to insufficient monitoring. Furthermore, in the event of a collision, there is a lack of appropriate sealing measures to prevent the valve from opening and causing a large amount of water leakage, resulting in a serious waste of water resources.

[0008] Preferably, the switching assembly includes a connecting cylinder, which is connected to the lower end of the lower valve stem and extends into the protective shell.

[0015] Preferably, the guide groove, docking shaft, housing, second spring and plug shaft are all equidistantly distributed from top to bottom along the interior of the moving plate, and the guide groove is opened in an inclined groove shape.

[0016] Secondly, an intelligent digital fire hydrant monitoring system is proposed, including a monitoring center, a central processing unit, an identification sensor, a water usage sensing module, and a monitoring sensing module. The monitoring center is wirelessly connected to the central processing unit, the identification sensor is wirelessly connected to the central processing unit, and both the water usage sensing module and the monitoring sensing module are wirelessly connected to the central processing unit.

[0017] The water usage sensing module includes a wireless early warning module, a pipeline water pressure monitor, a water usage monitoring module, and an ultrasonic flow meter, and all of the wireless early warning module, the pipeline water pressure monitor, the water usage monitoring module, and the ultrasonic flow meter are connected to the central processing unit.

[0018] The monitoring and sensing module includes a temperature sensor, a battery level sensor, a micro switch sensor, a wireless sensor, a tilt sensor, and a signal strength recognition sensor.

[0026] Temperature sensors are used to monitor equipment temperature and water temperature in water supply networks;

[0027] A battery level sensor is used to monitor the remaining battery level in real time and prompt timely battery replacement.

[0028] Micro-switch sensors are used to comprehensively monitor the movement of water flow in fire hydrants;

[0029] Wireless sensors are used in conjunction with electronic maps to comprehensively monitor the geographical information of the equipment;

[0030] A tilt sensor is used to monitor the tilt of the fire hydrant installation and trigger an alarm when the tilt exceeds a preset threshold.

[0031] Signal strength identification sensors are used to adjust the signal conditions of the monitoring system.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] This invention incorporates a monitoring system, including modules and sensors, to achieve unified management, real-time monitoring, equipment positioning, real-time early warning, auxiliary management, and data analysis. This enhances the safety and security of fire hydrants. Furthermore, the fire hydrant features a double-sealing device and an anti-collision device. The connection and cooperation between the sealing raft plate and the first and second openings create a double-sealing structure, ensuring stable valve body sealing and efficient sealing in case of subsequent valve body collision damage, preventing leakage and gushing. Additionally, the baffles on both sides of the valve body increase the strength of the inner wall, providing impact resistance and preventing breakage in the event of a collision.

[0034] The ball-shaped rod design allows the upper and lower valve rods to move and connect, preventing the entire valve rod from breaking in the event of a collision and reducing leakage when the valve body is damaged.

[0035] The double sealing device allows the lower valve stem to be pushed down in conjunction with the upper valve stem when the rotating rod moves it downward. This releases the sealing valve disc located outside the lower valve stem, eliminating the seal between it and the middle of the inlet pipe, thus releasing the primary seal. Simultaneously, the downward movement of the lower valve stem also activates the switching component, enabling the rotating disc inside the protective shell to rotate 180°, connecting the first opening with the second opening in the protective shell, thus releasing the secondary seal. This allows water from the pipeline to quickly enter the valve body for subsequent fire extinguishing. The double sealing structure enhances the valve body's sealing performance, ensuring that it remains in a highly efficient sealing state even in the event of collision damage, preventing water leakage and gushing from the valve body.

[0036] The switching component is configured such that the connecting cylinder can move down synchronously with the lower valve stem, and the rotating cylinder connected to the inside of the connecting cylinder can pre-drive the rotating block connected to the bottom to move down, so that the rotating block moves from the first annular groove at the upper end of the sleeve into the second annular groove. When the limiting blocks on both sides of the rotating block abut against the second annular groove, the rotating block rotates 180° through the transmission effect of the convex shaft inside the lower end of the connecting cylinder and the transmission groove opened on the outside of the rotating cylinder. This causes the turntable connected to the bottom of the rotating block to rotate in linkage, so as to satisfy the linkage release or closure of the secondary sealing structure.

[0037] The arrangement of the rotating plate, filter screen, connecting shaft, fan blades, and scraper allows the rotating plate connected to the bottom to be driven simultaneously when the turntable rotates 180° with the transmission. The filter screen connected to one side of the rotating plate can then rotate to the bottom of the second opening to achieve filtration and blockage, reducing the blockage of the first and second openings by external impurities and preventing water inlet blockage. At the same time, during water intake, the fan blades and scraper can rotate along the outside of the connecting shaft to scrape and clean the outside of the filter screen and accelerate the water intake rate.

[0038] The anti-collision component is designed so that when the valve body, valve cover, and inlet pipe are connected, the trigger rod located at the top of the moving plate and extending through the upper part of the vertical plate will connect with the bottom of the valve cover and move downward as it is squeezed. In this way, the moving plate will move downward along the interior of the vertical plate, and the guide grooves opened at various points inside will move downward simultaneously. The docking shafts that are connected to the inside of the guide grooves can push the housing outward through the inclined direction of the guide grooves. As a result, the second spring and the plug-in shaft inside the housing can push the baffle outward, so that the baffle is in close contact with the inner wall of the valve body, thereby strengthening the structural strength of the inner wall of the valve body and ensuring that the valve body has a certain impact resistance when a collision occurs, reducing the probability of collision breakage.

Detailed Implementation

[0048] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0049] Please see Figure 1 and Figure 3 This invention provides an intelligent digital fire hydrant, including a valve body 1, a valve cover 2 at the upper end of the valve body 1, water outlet pipes 3 fixed on both sides of the upper end of the valve body 1, a water inlet pipe 4 bolted to the lower end of the valve body 1, a flange base 5 fixed at the bottom of the water inlet pipe 4, an intelligent monitoring box 6 installed on the outside of the valve body 1, a rotating rod 7 rotatably installed at the upper end of the valve body 1, the lower end of the rotating rod 7 being threadedly connected to an upper valve stem 8, and the upper end of the upper valve stem 8 being vertically limited and connected to the valve body 1, and also including a double sealing device 9 located inside the valve body 1 and connected to the lower end of the upper valve stem 8 and an anti-collision device 10 located at the upper end of the water inlet pipe 4.

[0050] Specifically, when installation is required, the flange base 5 can be bolted to the ground to ensure a secure installation of the fire hydrant. When use is required, the external pipe can be connected to the open outlet pipe 3, and the upper valve stem 8, which is threaded to the lower end of the rotating rod 7, can be rotated to move the upper valve stem 8 downward, thereby enabling the double sealing device 9 to operate in conjunction with the valve body 1. This releases the double sealing effect of the double sealing device 9, allowing water to enter the valve body 1 and flow along the outlet pipes 3 on the left and right sides of the upper end of the valve body 1 into the external pipe for subsequent fire extinguishing activities.

[0051] On the other hand, please see Figure 2 This application also proposes an intelligent digital fire hydrant monitoring system, including a monitoring center, a central processing unit, an identification sensor, a water usage sensing module and a monitoring sensing module. The monitoring center is wirelessly connected to the central processing unit, the identification sensor is wirelessly connected to the central processing unit, and both the water usage sensing module and the monitoring sensing module are wirelessly connected to the central processing unit.

[0052] The water usage sensing module includes a wireless early warning module, a pipeline water pressure monitor, a water usage monitoring module, and an ultrasonic flow meter, and all of these components are connected to the central processing unit.

[0053] The monitoring and sensing module includes a temperature sensor, a battery level sensor, a micro switch sensor, a wireless sensor, a tilt sensor, and a signal strength recognition sensor. All of these sensors are connected to the central processing unit.

[0054] Specifically, when the wireless early warning module detects that the pipeline pressure is greater than the high pressure warning threshold or less than the low pressure warning threshold, it immediately reports a low pressure alarm and uploads the real-time water pressure value at that time. The low pressure warning threshold is set to the national standard of 0.1 MPa by default and can be set remotely.

[0055] The pipeline water pressure monitor is an intelligent water pressure monitoring terminal installed on the water supply section of the fire hydrant water supply network. It collects water pressure information in the fire pipeline network at a fixed frequency according to the pre-set collection and upload cycles.

[0056] The water usage monitoring module can operate when the fire hydrant is opened, record the opening and closing time of the fire hydrant, and send the information to the monitoring room through the fire hydrant monitoring platform for recording. It also sends the water usage information to the mobile phones of the management personnel via SMS so that the patrol team can stop and deal with it in a timely manner.

[0057] When the valve body is open, the ultrasonic flow meter can measure water usage and dynamically upload the code value information to the application server via the 4G / NB-IoT network. Finally, the software displays the dynamic data.

[0058] Temperature sensors can monitor the temperature of equipment and the water temperature of the water supply network. The equipment can promptly upload information on whether the water is frozen, along with other data, to the application server via 4G / NB-IoT network, which is then displayed by the software system.

[0059] The battery level sensor can upload the current battery level information of the fire hydrant, along with other data, to the application server via a 4G / NB-IoT network, prompting the user to replace the battery in time.

[0060] The micro-switch sensor can comprehensively monitor the water flow status of fire hydrants and trigger alarms by switching on and off the hydrant valve through a self-developed feature recognition algorithm.

[0061] Wireless sensors combined with electronic maps comprehensively monitor the geographical information of equipment and complete the electronic layout of smart fire hydrants;

[0062] The tilt sensor comprehensively monitors the installation status of fire hydrants and calculates the tilt angle of the equipment through a self-developed feature recognition algorithm. When the tilt of the intelligent fire hydrant cover exceeds the preset threshold, an alarm is triggered. The main function of the sensor is to detect the tipping, and the set indicator is that an alarm is triggered when the tilt angle is greater than 30 degrees.

[0063] The signal strength identification sensor can upload the current signal status of the fire hydrant, along with other data, to the application server via a 4G / NB-IoT network, and adjust the signal status around the device in a timely manner.

[0064] When the valve is open, the identification sensor scans the legitimate mobile app user card to confirm the user's identity and complete the identification of legitimate water use.

[0065] Specifically, with the cooperation of the aforementioned monitoring systems, intelligent fire hydrants can achieve the following advantages:

[0066] Unified Management: The quantity, network operation status, deployment records, and early warning records of various sensing devices such as fire hydrants, indoor fire cabinets, sprinklers, smoke sensors, and temperature and humidity sensors are all managed in a unified and clear manner.

[0067] Real-time monitoring: Various sensing devices are continuously connected to the network for monitoring around the clock. The IoT cloud platform monitors a series of indicators such as device network status and early warning data in real time to ensure timely and efficient early warning.

[0068] Equipment location: By combining geographic information systems, data visualization is displayed to accurately locate safety hazards that can be distinguished between indoor and outdoor environments, and to effectively monitor the location and status of equipment.

[0069] Real-time alerts: Once the monitored data is found to exceed the risk warning threshold, real-time alerts will be sent to the relevant responsible personnel through platform alerts, SMS alerts, and telephone voice alerts.

[0070] Data report analysis: Data query and analysis, data can be displayed in various ways such as band charts and pie charts, and data periodic changes are clear at a glance.

[0071] Please see Figures 4-6 In this embodiment, the double sealing device 9 includes a ball rod 91, which is connected to the lower end of the upper valve rod 8 and the lower end of the ball rod 91 is connected to the lower valve rod 92. This allows the upper valve rod 8 and the lower valve rod 92 to be connected. With the cooperation of the ball rod 91, multi-directional rotation can be achieved, ensuring that the entire valve rod is less likely to break in the event of a collision, thus improving the anti-collision protection effect. A sealing valve disc 93 is sleeved on the outside of the lower valve rod 92 and abuts against the inside of the water inlet pipe 4, thereby achieving a first-level sealing effect. The left and right sides of the sealing valve disc 93 are connected to the guide rod 94, and the guide rod 94 is vertically fixed to the left and right sides of the inside of the water inlet pipe 4 to ensure the stability of the opening and closing process of the sealing valve disc 93. A switching component 95 is provided at the lower end of the lower valve rod 92. A protective shell 96 is connected to the outside of the switching component 95 and the protective shell 96 is connected to the inside of the flange base 5.

[0072] The switching component 95 includes a connecting cylinder 951, which is connected to the lower end of the lower valve stem 92 and extends into the protective shell 96. A convex shaft 952 is located inside the lower left side of the connecting cylinder 951. The convex shaft 952 is inserted into the rotating cylinder 953, which is vertically inserted into the connecting cylinder 951. A transmission groove 954 is formed on the outside of the connecting cylinder 951, and the inside of the transmission groove 954 is connected to the convex shaft 952. This forms a downward rotation transmission structure, allowing the rotating cylinder 953 to rotate as it moves downward. The bottom of the rotating cylinder 953 is fixedly connected to the rotating block 955, thus enabling the rotating block 955 to rotate. Driven by the synchronous rotation of 5, limiting blocks 956 are fixed on both sides of the rotating block 955. A sleeve 957 is sleeved on the outside of the rotating block 955, and the sleeve 957 is fixedly connected to the inside of the protective shell 96. The upper and lower sides of the sleeve 957 are respectively provided with a first annular groove 958 and a second annular groove 959. The first annular groove 958 and the second annular groove 959 are respectively connected to the outside of the limiting block 956. That is, the rotating block 955 can be rotated 180° in both directions by the limiting blocks 956 on both sides and the limiting connection with the first annular groove 958 or the second annular groove 959, so as to meet the linkage opening and closing of the subsequent secondary sealing structure.

[0073] The rotating block 955 has a turntable 97 docked at its bottom. The turntable 97 is movably embedded inside the lower end of the protective shell 96. The turntable 97 has a first opening 98 on its right side. The turntable 97 has a rotating plate 99 docked at its lower middle. A filter screen 910 is installed on the right side of the rotating plate 99. The position of the filter screen 910 is opposite to the position of the first opening 98. A connecting shaft 911 is connected to the middle of the filter screen 910. A fan blade 912 is installed on the outside of the connecting shaft 911. A scraper 913 is provided at the upper end of the fan blade 912. The lower left side of the protective shell 96 has a second opening 914 that is symmetrically opposite to the first opening 98 and the diameter of the filter screen 910.

[0074] The ball rod 91 has smooth spherical shapes at both its upper and lower ends, and the upper and lower spheres of the ball rod 91 are respectively embedded in the bottom of the upper valve rod 8 and the top of the lower valve rod 92, ensuring that the ball rod 91 can achieve movable docking between the bottom of the upper valve rod 8 and the lower valve rod 92. In the event of a collision, the problem of the entire valve rod breaking can be avoided.

[0075] The transmission groove 954 is spirally grooved, and its transmission distance is longer than the distance between the first annular groove 958 and the second annular groove 959. This ensures that when the transmission groove 954 rotates, it can adapt to the distance between the first annular groove 958 and the second annular groove 959 to achieve stable forward and reverse 180° rotation. The first annular groove 958 and the second annular groove 959 are symmetrically opened vertically along the inside of the sleeve 957, and there is a limiting distance between them. This limiting cooperation between the first annular groove 958 and the second annular groove 959 allows the rotating block 955 to move up and down. When the limiting blocks 956 on both sides are embedded in the first annular groove 958 or the second annular groove 959, stable forward and reverse 180° rotation adjustment is achieved.

[0076] Specifically, when this fire hydrant is to be used, by rotating the rotating rod 7, the upper valve rod 8 connected to the bottom is threaded and driven, causing the upper valve rod 8 to push down the ball rod 91 connected to the bottom. As the ball rod 91 is pushed down, the lower valve rod 92 connected to the bottom of the ball rod 91 can move down the externally fitted sealing valve disc 93, so that the sealing valve disc 93 releases the sealing effect against the middle of the water inlet pipe 4. At the same time, when the sealing valve disc 93 moves down, it can be guided by the guide rods 94 connected on both sides to achieve a stable downward opening movement.

[0077] Simultaneously, as the lower valve stem 92 moves downward, the connecting cylinder 951, which is connected to the bottom of the lower valve stem 92, will move downward along the middle of the protective shell 96. During the downward movement of the connecting cylinder 951, the convex shaft 952 located inside the lower left side of the connecting cylinder 951 will drive the rotating cylinder 953 downward in advance. This will cause the rotating block 955 located at the bottom of the rotating cylinder 953 to move from the first annular groove 958 at the upper end of the sleeve 957 to the second annular groove 959 at the lower end through the limiting cooperation of the limiting blocks 956 on both sides. When the rotating block 955 moves into the second annular groove 959 and performs abutment movement, the convex shaft 952, which moves downward with the connecting cylinder 951, will engage with the opening on the outside of the rotating cylinder 953. The transmission groove 954 drives the rotating drum 953 to rotate in accordance with the spiral direction of the transmission groove 954. In this way, the turntable 97 connected to the bottom of the rotating block 955 will rotate 180° along the inside of the protective shell 96. Thus, the first opening 98 on the right side of the turntable 97 will rotate to the second opening 914 on the lower left side of the protective shell 96, so that the first opening 98 and the second opening 914 are connected. Thus, with the opening of the sealing valve 93 and the connection between the first opening 98 and the second opening 914, the double sealing effect can be released, allowing water from the pipeline to enter the valve body 1 and enter the external pipeline along the water outlet pipe 3 for fire extinguishing.

[0078] If the upper valve rod 8 is pulled upward by reversing the rotating rod 7, the lower valve rod 92 can move upward again, causing the sealing valve disc 93 to abut against the middle of the inlet pipe 4 to achieve a first-level seal. At the same time, the connecting cylinder 951 can move upward synchronously, driving the rotating cylinder 953 and the rotating block 955 to move upward. When the rotating block 955 moves from the second annular groove 959 into the first annular groove 958, and with the limiting effect of the limiting blocks 956 on both sides, it abuts against the first annular groove 958 for limitation, the convex shaft 952 provided on the lower left side of the connecting cylinder 951 will again abut against the rotating cylinder 953. The externally opened transmission groove 954 drives the rotating drum 953 to rotate 180° in the opposite direction. In this way, the turntable 97 connected to the lower end of the rotating block 955 can rotate 180° in the opposite direction synchronously, so that the first opening 98 and the second opening 914, which were originally in a connected state, can separate and close. This satisfies the realization of the two-stage sealing structure. Thus, water can be stopped from entering. In the event of a collision, the double sealing structure can improve the sealing performance and prevent water leakage and water waste caused by collision damage.

[0079] Secondly, when the turntable 97 is driven to rotate 180° in both directions, the rotating plate 99 connected to the lower end of the turntable 97 can rotate synchronously in both directions. In this way, the filter screen 910 located inside the right side of the rotating plate 99 can cover the outer end of the second opening 914 at the bottom during water intake, filtering and blocking, and preventing large particles from clogging the first opening 98 and the second opening 914. At the same time, in conjunction with the fan blade 912 and scraper 913 located at the connecting shaft 911 in the middle of the filter screen 910, the fan blade 912 and scraper 913 can be rotated during water intake to meet the rotating scraping cleaning of the outside of the filter screen 910, scraping away the attached impurities, ensuring flow, reducing the probability of water intake clogging, and at the same time, the rotation of the fan blade 912 can accelerate the water intake rate.

[0080] Please see Figures 7-8 In this embodiment, the anti-collision device 10 includes a vertical plate 101, which is vertically installed on the upper left and right sides of the water inlet pipe 4. A first spring 102 is installed at the lower end of each of the left and right vertical plates 101. The upper end of the first spring 102 is connected to a movable plate 103, which is vertically movably installed inside the vertical plate 101. A trigger rod 104 is vertically fixedly connected to the top of the movable plate 103. Guide grooves 105 are equidistantly provided inside the movable plate 103. The guide groove 105 is connected to the docking shaft 106, and the docking shaft 106 is located on both sides of the outer end of the housing 107. The housing 107 is equipped with a second spring 108, and a plug shaft 109 is inserted laterally inside the housing 107. One end of the plug shaft 109 is connected to the second spring 108, and the other end of the plug shaft 109 is connected to the baffle 1010. The baffle 1010 is connected to the inner wall of the valve body 1, and the baffle 1010 is set in a semi-arc metal plate shape.

[0081] The trigger rod 104 is vertically fixed to the upper end of the moving plate 103, and the trigger rod 104 vertically penetrates the upper end of the vertical plate 101 and connects to the bottom of the valve cover 2. This ensures that when the valve body 1, valve cover 2 and water inlet pipe 4 are connected, the trigger rod 104 can be triggered to move downward, so that the subsequent baffle 1010 is tightly attached to the inner wall of the valve body 1, improving the structural strength and avoiding the probability of collision damage. The guide groove 105, docking shaft 106, housing 107, second spring 108 and plug shaft 109 are all equally distributed from top to bottom along the interior of the moving plate 103. The guide groove 105 is opened in an inclined groove shape. Through the inclined guidance of the guide groove 105, the docking shaft 106, housing 107, second spring 108 and plug shaft 109 can be linked to operate simultaneously to meet the reinforcement of the baffle 1010 by pushing outward.

[0082] Specifically, during the docking of valve body 1 and inlet pipe 4, the vertical plate 101 can be moved into both sides of the valve body 1. The trigger rod 104, located at the upper end of the movable plate 103 and extending through the upper end of the vertical plate 101, will engage with the interior of the valve cover 2 during docking of valve body 1 and inlet pipe 4, thereby pushing the trigger rod 104 downward. This allows the movable plate 103 to move downward along the interior of the vertical plate 101. The downward movement of the movable plate 103 simultaneously causes the guide grooves 105 located on the exterior of the movable plate 103 to move downward. The docking shafts 106, which are connected to the guide grooves 105 at various locations, will cooperate with the tilting direction of the guide grooves 105 to push the housing 107 outward. Through the outward movement of the housing 107, the second spring 108 and the plug shaft 109 located inside the housing 107 will cooperate to squeeze the baffle 1010 at the outer end, so that the baffle 1010 is tightly attached to the inside of the valve body 1, thereby improving the internal structural strength of the valve body 1. When a collision occurs, it can achieve a certain impact buffering effect to avoid the valve body 1 from being damaged by collision.
