[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] The present invention sets up a monitoring system, that is, the modules and sensors set inside the monitoring system, which can meet the needs of unified management, real-time monitoring, equipment positioning, real-time warning, auxiliary management and data analysis, making the use of fire hydrants safer and more anti-theft. At the same time, a double sealing device and an anti-collision device are also set inside the fire hydrant. With the connection and cooperation between the sealing raft plate and the first opening and the second opening, a double sealing structure can be formed to ensure the stability of the valve body seal and efficient sealing when the valve body is subsequently damaged by collision, avoiding the occurrence of water leakage and gushing problems. At the same time, the baffles on both sides of the valve body can increase the strength of the inner wall of the valve body, so that when a collision problem occurs, it has a certain impact resistance effect, avoiding the occurrence of collision and fracture problems.

[0035] The setting of the ball rod, that is, the docking of the ball rod, can make the upper valve stem and the lower valve stem movably docked, so as to avoid the problem of the whole valve stem breaking in the event of a collision, and reduce the occurrence of water leakage problems when the valve body is damaged by collision.

[0036] The setting of the double closing device, that is, when the rotating rod drives the upper valve stem to move downward, the lower valve stem can be pushed down in conjunction. In this way, the sealing valve disc provided on the outside of the lower valve stem can release the sealing effect offsetting the middle end of the water inlet pipe, thereby realizing the release of the first-level seal. At the same time, when the lower valve stem moves downward, the switching component can also be operated in conjunction, so that the switching component can realize 180° switching and driving of the turntable provided inside the protective shell to meet the connection between the first opening and the second opening provided in the protective shell, thereby realizing the release of the secondary seal. As a result, the pipeline water shell quickly enters the interior of the valve body for subsequent water discharge and fire extinguishing. Through the setting of the double sealing structure, the sealing of the valve body can be enhanced to ensure that when the valve body is damaged by collision, it is still in an efficient sealing state, thereby avoiding the occurrence of water leakage and gushing problems in the valve body.

[0037] The setting of the switching component, that is, the connecting cylinder can move downward synchronously with the lower valve stem, and the rotating cylinder docked inside the connecting cylinder can pre-drive the rotating block connected to the bottom to move downward, so that the rotating block moves from the first ring groove at the upper end of the sleeve into the second ring groove, and when the limit blocks on both sides of the rotating block are against the second ring groove, the transmission effect of the convex shaft provided inside the lower end of the connecting cylinder and the transmission groove opened on the outside of the rotating cylinder is used to rotate 180°, so that the turntable docked at the bottom of the rotating block is rotated in conjunction, so as to meet the linkage release or closing of the secondary sealing structure.

[0038] The setting of the rotating plate, filter screen, connecting shaft, fan blades and scraper strips, that is, when the turntable rotates 180° with the transmission, the rotating plate connected to the bottom can be driven synchronously, and the filter screen docked on one side of the rotating plate can be rotated to the bottom of the second opening to achieve filtration and blocking, reducing external impurities blocking the first opening and the second opening, causing the occurrence of water inlet blockage problems. At the same time, when water is entering, the fan blades and scraper strips can rotate along the outside of the connecting shaft to achieve scraping and cleaning of the outside of the filter screen and accelerate the water inlet rate.

[0039] The setting of the anti-collision component, that is, when the valve body, the valve cover and the water inlet pipe are connected, the trigger rod provided on the top of the movable plate and passing through the upper end of the vertical plate will be connected with the bottom of the valve cover and move downward with the extrusion. In this way, the movable plate will move downward along the inside of the vertical plate, and the guide grooves opened in various places inside will move downward at the same time, and the docking shaft docked inside the guide grooves at various places can push the shell outward according to the inclined direction of the guide grooves. Therefore, the second spring and the plug-in shaft provided inside the shell can push the baffle outward, so that the baffle is in close contact with the inner wall of the valve body, so as to strengthen the structural strength of the inner wall of the valve body, ensure that when the valve body has a collision problem, it has a certain impact resistance effect and reduces the chance of collision breakage.

DETAILED DESCRIPTION

[0049] In order to further explain the technical solution of the present invention, specific embodiments are described in detail below.

[0050] See also Figure 1 and Figure 3 The present invention provides an intelligent digital fire hydrant, comprising a valve body 1, a valve cover 2 being provided at the upper end of the valve body 1, water outlet pipes 3 being fixedly provided on both sides of the upper end of the valve body 1, a water inlet pipe 4 being bolted to the lower end of the valve body 1, a flange base 5 being fixed to the bottom of the water inlet pipe 4, an intelligent monitoring box 6 being installed outside the valve body 1, a rotating rod 7 being rotatably installed at the upper end of the valve body 1, the lower end of the rotating rod 7 being threadedly connected to the upper valve stem 8, and the upper end of the upper valve stem 8 being vertically limitedly docked with the valve body 1, and further comprising a double closing device 9 being provided inside the valve body 1 and connected to the lower end of the upper valve stem 8, and an anti-collision device 10 being provided at the upper end of the water inlet pipe 4.

[0051] Specifically, when installation is to be carried out, the flange base 5 can be docked with the ground bolts to achieve a firm installation of the fire hydrant as a whole. When use is to be carried out, the external pipeline can be connected to the opened water outlet pipe 3, and the upper valve stem 8 threadedly connected to the lower end of the rotating rod 7 can be rotated to move the upper valve stem 8 downward to achieve the linkage operation of the double closing device 9, so that the double closing device 9 releases the double sealing effect. In this way, the pipeline water can enter the interior of the valve body 1 and enter the external pipeline along the water outlet pipe 3 provided on the left and right sides of the upper end of the valve body 1 for subsequent fire extinguishing activities.

[0052] On the other hand, see Figure 2 , the present application also proposes an intelligent digital fire hydrant monitoring system, including a monitoring center, a central processing unit, an identity recognition sensor, a water consumption sensing module and a monitoring sensing module, the monitoring center is wirelessly connected to the central processing unit, the identity recognition sensor is wirelessly connected to the central processing unit, and the water consumption sensing module and the monitoring sensing module are both wirelessly connected to the central processing unit;

[0053] The water usage sensing module includes a wireless early warning module, a pipe network water pressure monitor, a water usage monitoring module and an ultrasonic flow meter, and the wireless early warning module, the pipe network water pressure monitor, the water usage monitoring module and the ultrasonic flow meter are all connected to the central processing unit;

[0054] The monitoring sensor module includes a temperature sensor, a battery remaining sensor, a micro switch sensor, a wireless sensor, a tipping sensor and a signal strength recognition sensor. The temperature sensor, the battery remaining sensor, the micro switch sensor, the wireless sensor, the tipping sensor and the signal strength recognition sensor are all connected to the central processing unit;

[0055] Specifically, when the wireless warning module detects that the pipe network pressure is greater than the high pressure warning threshold or less than the low pressure warning threshold, it will immediately report a low pressure alarm and upload the real-time water pressure value at that time. The low pressure warning threshold defaults to the national standard 0.1Mpa and supports remote setting.

[0056] The pipe network water pressure monitor is installed on the water supply part of the fire hydrant water supply network. According to the pre-set collection cycle and upload cycle, the water pressure information in the fire pipe network is collected at a fixed frequency;

[0057] The water usage monitoring module can work 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. The water usage information is also sent to the law enforcement personnel's mobile phones in the form of text messages, so that the inspection team can stop and deal with it in time.

[0058] When the valve body is open, the ultrasonic flow meter measures water consumption and dynamically uploads the code value information to the application server via the 4G / NB-IOT network. The dynamic data is ultimately displayed by the software.

[0059] The temperature sensor can monitor the temperature of the device and the water temperature of the water supply network. The device can promptly upload the result information of whether the water is frozen along with other data via the 4G / NB-IOT network to the application server, and finally display it in the software system;

[0061] The micro switch sensor can fully monitor the water flow status of the fire hydrant and realize the valve switch trigger alarm through the independently developed feature recognition algorithm;

[0062] Wireless sensors combined with electronic maps comprehensively monitor equipment geographic information and complete the electronic layout of smart fire hydrants;

[0063] The tipping 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 a preset threshold, an alarm is triggered. The tilting detection is mainly achieved through the angle sensor, and the alarm is set to an angle greater than 30 degrees.

[0064] The signal strength identification sensor can upload the current signal status of the fire hydrant along with other data to the application server via the 4G / NB-IOT network, and adjust the signal status around the device in a timely manner;

[0068] Real-time monitoring: All types of sensor equipment are monitored online around the clock. The IoT cloud platform monitors a series of indicators such as equipment network status and early warning data in real time to ensure timely and efficient early warning.

[0069] Equipment positioning: Combined with geographic information systems, data visualization is performed to accurately locate safety hazards indoors and outdoors, enabling effective monitoring of equipment location and status;

[0070] Real-time warning: Once the monitoring data exceeds the risk warning threshold, a real-time warning will be issued to the relevant responsible personnel through platform warning, mobile phone text message warning, and telephone voice warning;

[0071] Data report analysis: data query and data analysis, data can be displayed in various forms such as band graphs and pie charts, and data cycle changes are clear at a glance.

[0072] See also Figure 4-Figure 6 The double closing device 9 in this embodiment includes a ball rod 91, which is connected to the lower end of the upper valve stem 8, and the lower end of the ball rod 91 is connected to the lower valve stem 92, thereby realizing the docking of the upper valve stem 8 and the lower valve stem 92, and with the cooperation of the ball rod 91, it can realize multi-directional rotation, ensuring that when a collision problem occurs later, it is not easy to cause the entire valve stem to break, thereby improving the anti-collision protection effect. A sealing valve flap 93 is provided on the outside of the lower valve stem 92, and the sealing valve flap 93 is abutted 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 flap 93 are connected to the guide rod 94, and the guide rod 94 is vertically fixedly connected to the left and right sides of the inside of the water inlet pipe 4 to ensure the stability of the upper and lower opening and closing process of the sealing valve flap 93. A switching component 95 is provided at the lower end of the lower valve stem 92, and 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.

[0073] Among them, the switching component 95 includes a connecting cylinder 951, which is connected to the lower end of the lower valve stem 92, and the connecting cylinder 951 penetrates into the interior of the protective shell 96, and a convex shaft 952 is provided inside the left side of the lower end of the connecting cylinder 951. The convex shaft 952 is inserted into the interior of the rotating cylinder 953, and the rotating cylinder 953 is vertically inserted into the interior of the connecting cylinder 951. A transmission groove 954 is provided on the outside of the connecting cylinder 951, and the interior of the transmission groove 954 is connected to the convex shaft 952, thereby forming a downward rotation transmission structure, so that the rotating cylinder 953 rotates as it moves downward, and the bottom of the rotating cylinder 953 is fixedly connected to the rotating block 955, which can realize the rotating block 95 5 is driven by the synchronous rotation, and limit 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. A first annular groove 958 and a second annular groove 959 are respectively opened on the upper and lower sides of the sleeve 957, and the first annular groove 958 and the second annular groove 959 are respectively connected to the outside of the limit block 956. That is, the rotating block 955 can ensure that the rotating block 955 can rotate 180 degrees in both directions through the limiting connection effect of the limit blocks 956 on both sides and the first annular groove 958 or the second annular groove 959 to meet the linkage opening and closing of the subsequent secondary sealing structure.

[0074] Among them, a turntable 97 is docked at the bottom of the rotating block 955, and the turntable 97 is movably embedded in the lower end of the protective shell 96. A first opening 98 is opened on the right side of the turntable 97, and a turn plate 99 is docked at the middle of the lower end of the turntable 97. A filter screen 910 is installed on the right side of the turntable 99, and 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, and a fan blade 912 is installed on the outside of the connecting shaft 911. A scraper strip 913 is provided on the upper end of the fan blade 912. A second opening 914 symmetrically arranged at the upper and lower ends is opened on the left side of the lower end of the protective shell 96, and the diameter of the second opening 914 is consistent with the diameter of the first opening 98 and the filter screen 910.

[0075] Among them, the upper and lower ends of the ball rod 91 are both smooth spherical, and the upper and lower balls of the ball rod 91 are respectively embedded in the bottom of the upper valve stem 8 and the top of the lower valve stem 92, ensuring that the ball rod 91 can realize the movable docking between the bottom of the upper valve stem 8 and the lower valve stem 92, and when a collision occurs, the problem of breakage of the entire valve stem can be avoided.

[0076] Among them, the transmission groove 954 is opened in the shape of a spiral groove as a whole, and the transmission distance of the transmission groove 954 is longer than the distance between the first ring groove 958 and the second ring groove 959, ensuring that when the transmission groove 954 performs rotational transmission, it can adapt to the distance between the first ring groove 958 and the second ring groove 959 to meet the requirements of stable forward and reverse 180° rotation activities; the first ring groove 958 and the second ring groove 959 are opened symmetrically up and down along the inside of the sleeve 957, and there is a limiting distance between the first ring groove 958 and the second ring groove 959, that is, through the limiting cooperation of the first ring groove 958 and the second ring groove 959, the rotating block 955 can be moved up and down, and when the limiting blocks 956 on both sides are embedded in the first ring groove 958 or the second ring groove 959, stable forward and reverse 180° rotation adjustment activities can be performed.

[0077] Specifically, when the fire hydrant is to be used, the upper valve stem 8 connected to the bottom is threadedly driven by rotating the rotating rod 7, so that the upper valve stem 8 pushes down the ball rod 91 connected to the bottom. As the ball rod 91 is pushed down, the lower valve stem 92 docked at the bottom of the ball rod 91 can realize the downward movement of the sealing valve disc 93 provided on the outside, so that the sealing valve disc 93 releases the sealing effect against the middle end of the water inlet pipe 4. At the same time, when the sealing valve disc 93 moves downward, it can be guided by the guide rods 94 docked on both sides to achieve a stable downward movement and opening activity.

[0078] At the same time, when the lower valve stem 92 moves downward, the connecting cylinder 951 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 provided on the left inner side of the lower end of the connecting cylinder 951 will pre-drive the downward movement of the rotating cylinder 953, so that the rotating block 955 provided at the bottom of the rotating cylinder 953 will move from the first annular groove 958 opened at the upper end of the sleeve 957 to the second annular groove 959 opened at the lower end through the limiting cooperation of the limiting blocks 956 provided on both sides. When the rotating block 955 moves into the second annular groove 959 and performs the offset movement, the convex shaft 952 that moves downward with the connecting cylinder 951 will cooperate with the The transmission groove 954 is driven to rotate the rotating drum 953 in accordance with the spiral direction of the transmission groove 954. As a result, the turntable 97 docked at the bottom of the rotating block 955 will rotate 180 degrees along the inside of the protective shell 96. In this way, the first opening 98 opened on the right side of the turntable 97 will rotate to the second opening 914 opened on the left side of the lower end of the protective shell 96 to achieve communication between the first opening 98 and the second opening 914. In this way, as the sealing valve flap 93 opens and the first opening 98 is connected to the second opening 914, the double sealing effect can be released, allowing the pipeline water to enter the interior of the valve body 1 and enter the external pipeline along the outlet pipe 3 to perform fire extinguishing activities.

[0079] If the upper valve stem 8 is pulled upward by reversing the rotating rod 7, the lower valve stem 92 can be moved upward again, so that the sealing valve disc 93 is sealed against the middle end of the water inlet pipe 4 to achieve a first-level seal. At the same time, the connecting cylinder 951 can be moved upward synchronously to drive 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 cooperates with the limiting effect of the limiting blocks 956 on both sides to limit the first annular groove 958, the convex shaft 952 provided on the left side of the lower end of the connecting cylinder 951 will be again in contact with the rotating cylinder 953 The transmission groove 954 provided on the outside transmits the power, causing the rotating drum 953 to rotate 180° in the opposite direction. In this way, the rotating disk 97 connected to the lower end of the rotating block 955 can be synchronously rotated 180° in the opposite direction, so that the first opening 98 and the second opening 914, which were originally in a connected state, are separated and closed, that is, the secondary sealing structure is realized. As a result, water inflow can be stopped. In the event of a subsequent collision, the double sealing structure can improve the sealing performance and avoid water leakage and gushing after collision damage, which leads to water waste.

[0080] Secondly, when the turntable 97 is driven to rotate 180 degrees forward and backward, the rotating plate 99 connected to the lower end of the turntable 97 can rotate forward and backward synchronously. In this way, the filter 910 provided on the right side of the rotating plate 99 can cover the outer end of the second opening 914 at the bottom during water intake to filter and block the water, thereby preventing larger particles from clogging the first opening 98 and the second opening 914. At the same time, the fan blades 912 and the scraper strips 913 provided at the connecting shaft 911 in the middle of the filter 910 can be driven by the rotation of the fan blades 912 and the scraper strips 913 during water intake to meet the rotating scraping cleaning of the outside of the filter 910, scrape and clean the attached impurities, ensure fluidity, and reduce the chance of water inlet blockage. At the same time, the rotation of the fan blades 912 can accelerate the water inlet rate.

[0081] See also Figure 7-Figure 8 The anti-collision device 10 in this embodiment includes a vertical plate 101, which is vertically installed on the left and right sides of the upper end of the water inlet pipe 4. The lower ends of the left and right vertical plates 101 are both installed with first springs 102. The upper ends of the first springs 102 are connected to the movable plate 103, and the movable plate 103 is vertically movably installed inside the vertical plate 101. The top of the movable plate 103 is vertically fixedly connected to a trigger rod 104. The movable plate 103 has guide grooves 105 equidistantly provided inside. The interior of the guide groove 105 is connected to the docking shaft 106, and the docking shaft 106 is arranged on both sides of the outer end of the shell 107. A second spring 108 is installed inside the shell 107, and a plug-in shaft 109 is inserted horizontally into the shell 107. One end of the plug-in shaft 109 is connected to the second spring 108, and the other end of the plug-in 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 arranged in the shape of a semi-arc metal plate as a whole.

[0082] Among them, the trigger rod 104 is vertically fixed to the upper end of the movable plate 103, and the trigger rod 104 vertically penetrates the upper end of the vertical plate 101 and is connected to the bottom inner portion of the valve cover 2 to ensure that when the valve body 1 and the valve cover 2 are connected to the water inlet pipe 4, the downward movement of the trigger rod 104 can be triggered, so that the subsequent baffle 1010 is close to the inner wall of the valve body 1, thereby improving the structural strength and avoiding the chance of collision damage; the guide groove 105, the docking shaft 106, the shell 107, the second spring 108 and the plug-in shaft 109 are all equidistantly distributed from top to bottom along the inside of the movable plate 103, and the guide groove 105 is opened in the shape of an inclined groove as a whole. Through the inclined guidance of the guide groove 105, the docking shafts 106, the shell 107, the second spring 108 and the plug-in shaft 109 at each location can be simultaneously linked to run to meet the outward push and counteraction reinforcement of the baffle 1010.

[0083] Specifically, when the valve body 1 and the water inlet pipe 4 are docked, the vertical plate 101 can be moved into both sides of the interior of the valve body 1, and the trigger rod 104 provided at the upper end of the movable plate 103 and extending through the upper end of the vertical plate 101 will be in contact with the interior of the valve cover 2 when the valve body 1 and the water inlet pipe 4 are docked, so as to push the trigger rod 104 downward, thereby making the movable plate 103 move downward along the interior of the vertical plate 101, and the downward movement of the movable plate 103 can make the guide grooves 105 provided on the outside of the movable plate 103 move downward at the same time, so that The docking shaft 106 docked inside the guide groove 105 at each location will cooperate with the tilt direction of the guide groove 105 to realize the outward push of the shell 107. Through the outward movement of the shell 107, the second spring 108 and the plug-in shaft 109 provided inside the shell 107 will cooperate with each other to squeeze the baffle 1010 provided at the outer end, so that the baffle 1010 is close to the inside of the valve body 1, thereby improving the internal structural strength of the valve body 1, so that when a collision occurs, a certain impact buffering effect can be achieved to avoid the problem of collision, fracture and damage to the valve body 1.
