Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, and in particular to a smart fire hydrant and a smart fire hydrant monitoring system. Background Art

[0002] Fire hydrants are fixed firefighting facilities used for fire trucks to draw water from the municipal water supply network or outdoor fire water supply network to carry out firefighting operations, or directly connect water hoses and water guns to discharge water for firefighting operations. Since the water pressure required for fire water supply is relatively high, there are changes in the state of normal pressure, temporary high pressure, etc. in the fire pipeline. Once the fire pipeline leaks, it will bring greater economic losses than ordinary pipelines, and there are also potential fire hazards. Therefore, compared with municipal pipelines, the management requirements of fire pipelines are higher, and fire hydrants need to be inspected and maintained regularly.

[0003] Due to the large number of fire hydrant facilities in the city, their wide distribution and dispersion, some facilities are old and unmaintained (a fire hydrant is set up every 500 meters in the city). There are bad behaviors in the social environment, such as stealing fire water, occupying fire hydrants, and destroying fire hydrants. Leakage problems caused by vehicle collisions, pipe network ruptures, and aging of the main structure occur frequently. With limited maintenance personnel, some fire hydrants are not properly maintained, which increases the difficulty of maintenance and management. Furthermore, the common fire hydrants on the market have a simple structure and only have the function of switching water supply. They lack the function of IoT sensing. Their water pressure monitoring requires manual opening of the fire hydrant to release water for testing. The data collection is not accurate and paper records are not easy to preserve. Moreover, since the inspection process is led by inspection personnel, it is difficult to standardize the inspection behavior. Fire hydrant management is mainly based on human defense, and daily inspections are difficult. It is impossible to obtain the operating status of fire hydrants in the first time. Fire hydrants are often passively managed after a failure occurs, and it is difficult to proactively discover the safety hazards of fire hydrants. Therefore, there are problems of missed inspections of some fire hydrants and water shortages in pipelines. When an emergency fire occurs, the fire hydrants will not be able to play their due role.

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0021] Please combine Figure 1-3 The utility model discloses a smart fire hydrant that can detect the state of a fire hydrant in real time and give an alarm, has accurate data collection, can realize comprehensive supervision of fire hydrants, and reduces the difficulty of fire hydrant maintenance and management. The smart fire hydrant includes a fire hydrant body 100. The upper part of the fire hydrant body 100 is provided with at least one water outlet 110, and the water outlet 110 is used to connect with an external water pipe to provide water for fire fighting. An openable and closable water cover 120 is provided at the water outlet 110. The water cover 120 covers the water outlet 110 when the fire hydrant body 100 is in an idle state. When the fire hydrant needs to be used, the water cover 120 can be removed from the water outlet 110, which can avoid the problem of blockage of the fire hydrant body 100 caused by debris or small animals entering the inner cavity of the fire hydrant body 100 through the water outlet 110. The inner cavity of the fire hydrant body 100 is provided with a partition plate 130 above the water outlet 110. The partition plate 130 is fixed to the top of the fire hydrant body 100 by bolts and is sealed with the fire hydrant body 100 to prevent the fire water from entering the upper part of the partition plate 130 through the gap between the partition plate 130 and the fire hydrant body 100 during the use of the fire hydrant. The partition plate 130 separates the inner cavity of the fire hydrant body 100 to form an independent water outlet channel 140 and a control room 150. The water outlet channel 140 is connected with the water outlet 110 and is located below the control room 150. Due to the partition plate 130, when the fire hydrant is used, the fire water always flows out from the lower part of the partition plate 130 through the water outlet 110, thereby preventing the control room 150 from being soaked.

[0022] A plug cover 160 is provided on the top of the fire hydrant body 100 for sealing the control room 150 to prevent debris from entering the control room 150. The bottom of the water outlet channel 140 is connected to an external water supply pipe, which is a city fire waterway, so as to continuously provide fire water for the fire point when a fire occurs. A valve stem 170 is provided in the water outlet channel 140, which extends along the height direction of the fire hydrant body 100 and passes through the partition plate 130 and can be raised and lowered in the water outlet channel 140. The bottom end of the valve stem 170 is adjacent to the bottom of the water outlet channel 140, and a valve flap 180 is fixed to the bottom end of the valve stem 170 to seal and abut against the inner wall of the water outlet channel 140. The inner wall of the water outlet channel 140 is provided with an annular water groove 190 adjacent to the valve disc 180, that is, the inner diameter of the fire hydrant body 100 at the annular water groove 190 is larger than the inner diameter of the rest of the fire hydrant body 100, so that the valve disc 180 approaches or leaves the annular water groove 190 when the valve stem 170 is raised or lowered, so that the fire water flows into the water outlet channel 140, or the water outlet channel 140 is separated from the fire water so as to take water through the fire hydrant.

[0023] A temperature-pressure integrated sensor 200 and a liquid level sensor 300 are fixed to one side of the valve disc 180 adjacent to the water outlet 110, and the control room 150 contains a control circuit board 400 fixedly connected to the fire hydrant body 100 and electrically connected to the temperature-pressure integrated sensor 200 and the liquid level sensor 300, and a power supply device 500 for supplying power to the control circuit board 400. Preferably, the power supply device 500 is a lithium battery. A positioning sensor 600, a gravity sensor 700, and a 4G transmission module 800 that is electrically connected to the control circuit board 400 are installed on the control circuit board 400. Preferably, the temperature-pressure integrated sensor 200 and the liquid level sensor 300 are electrically connected to the control circuit board 400 through a signal line. In this embodiment, the temperature and pressure integrated sensor 200 can detect the water pressure and water temperature in the fire hydrant body 100 in real time, and determine whether there is water in the water outlet pipe of the fire hydrant body 100 and whether the water pressure is normal through the pressure measurement value detection, so as to avoid the problem of difficulty in extinguishing fires due to insufficient water pressure or lack of water during emergency use; the temperature in the fire hydrant body 100 is detected in real time through the temperature detection value to prevent the water in the fire hydrant body 100 from freezing, thereby causing the fire hydrant to fail to discharge water during emergency use. The liquid level sensor 300 can detect the water level at the valve flap 180 position in real time. Since the liquid level sensor 300 is arranged on the inner side of the valve flap 180, if the liquid level sensor 300 detects the water level when the valve flap 180 is closed, it means that there is a water leak at the valve flap 180. The gravity sensor 700 is used to collect gravity information of the fire hydrant body 100, and determine whether the fire hydrant is tilted or tilted based on the gravity information; the positioning sensor 600 can collect the position information of the fire hydrant body 100 and report it to the user platform through the 4G transmission module 800, so that the user can grasp the position of each fire hydrant and its related status information, and according to the position information of the fire hydrant, arrive at the location of the faulty fire hydrant in time and repair the fault to ensure that the function of the fire hydrant will not fail in an emergency.

[0024] In one embodiment, three water outlets 110 connected to the water outlet channel 140 are provided on the upper portion of the fire hydrant body 100. The three water outlets 110 include a first water nozzle 111 and a second water nozzle 112 which are arranged opposite to each other on the annular side surface of the fire hydrant body 100 and are used for being internally buckled with the fire hose, and a third water nozzle 113 which is located between the first water nozzle 111 and the second water nozzle 112 and is used for being threadedly connected to the water suction pipe of the vehicle-mounted water pump. In this way, according to different usage scenarios, the fire hydrant body 100 can be connected to the corresponding water intake device through different water outlets 110, so as to deliver the fire water of the urban fire pipe network to the fire point via the water intake device.

[0025] Please further combine Figure 2 and Figure 3In one embodiment, the valve stem 170 includes a rod body 171 fixedly connected to the valve disc 180, a rotating sleeve 172 fixed to the top of the rod body 171, an adjusting nut 173 fixed to the top of the rotating sleeve 172, a screw rod 174 passing through the partition plate 130 and extending from the bolt cover 160, a threaded hole communicating with the inner cavity of the rotating sleeve 172 is provided on the adjusting nut 173, the bottom end of the screw rod 174 is inserted into the inner cavity of the rotating sleeve 172 through the threaded hole, and the screw rod 174 is threadedly matched with the threaded hole of the adjusting nut 173. Further, the bolt cover 160 is fixedly connected to the top of the screw rod 174, and the bolt cover 160 is rotatably provided on the top of the fire hydrant body 100, and an operating hole 161 is provided on the ring side of the bolt cover 160. In this way, during the opening and closing process of the fire hydrant, the lever can be inserted into the operating hole 161, and the lever can be rotated to drive the bolt cover 160 to rotate. In this way, the bolt cover 160 will drive the screw rod 174 to rotate synchronously. Since the screw rod 174 is threadedly matched with the adjusting nut 173 above the rod body 171, during the rotation of the screw rod 174, the adjusting nut 173 will drive the rotating sleeve 172 and the rod body 171 to rise and fall relative to the screw rod 174, so that the valve disc 180 leaves or enters the annular water groove 190 to open and close the water passage between the fire hydrant body 100 and the external water supply pipe.

[0026] In this embodiment, the bolt cover 160 is rotatably mounted on the top of the fire hydrant body 100 through a snap-fit ​​structure, or the bolt cover 160 is threadedly connected to the top of the fire hydrant body 100. Preferably, the bolt cover 160 is threadedly connected to the top of the fire hydrant body 100. In one embodiment, a through hole for passing a screw rod is provided in the middle of the partition plate, and a sleeve 151 is provided at the through hole, which is sleeved on the screw rod and sealed with the partition plate. An annular baffle is provided at the edge of the partition plate, and an installation area for accommodating a control circuit board is formed between the sleeve and the annular baffle. The control circuit board is located in the installation area and fixed on the partition plate. A cover seal 152 is fixed on the top of the sleeve, and the edge of the cover seal 152 is sealed with the annular baffle. The upper part of the cover seal 152 is provided with a cylindrical part, and the annular side surface of the cylindrical part is provided with an external thread that is threaded with the inner surface of the bolt cover 160. In other words, the bolt cover 160 is rotatably mounted on the cover seal 152. In this way, the control circuit board 400 and the sensor and power supply device 500 mounted on the control circuit board 400 are encapsulated in the installation area, achieving waterproof protection for the above components to ensure the reliability of fire hydrant signal transmission.

[0027] In one embodiment, the outer wall of the fire hydrant body 100 is provided with a discharge pipe 191 connected to the water outlet channel 140 above the annular water groove 190, and a residual water discharge device 192 is provided at the discharge pipe 191. By providing the discharge pipe 191 and the residual water discharge device 192, after the fire hydrant is used once, the residual water discharge device 192 can be opened to discharge the residual fire water in the fire hydrant body 100, thereby avoiding the problem of bacteria breeding and fire hydrant pipe rust caused by long-term accumulation of water in the fire hydrant body 100. In addition, in this embodiment, the bottom of the fire hydrant body 100 is provided with a flange elbow 900 respectively connected to the water outlet channel 140 and the external water supply pipe, and the outer surface of the flange elbow 900 is provided with a mounting frame 910, so that the entire fire hydrant can be bolted to the ground through the mounting frame 910 to achieve the positioning of the fire hydrant, and the flange elbow 900 is used to introduce water from the urban fire pipe network into the fire hydrant body 100. It should be noted that, in the present embodiment, the flange elbow 900 is mainly applicable to the situation where the water outlet of the urban fire protection pipe network is on the wall. When the water outlet of the urban fire protection pipe network is located on the ground, the flange elbow 900 can be cancelled.

[0028] The utility model also discloses a smart fire hydrant monitoring system, which includes the above-mentioned smart fire hydrant, and also includes a user platform server connected to the smart fire hydrant and a user terminal connected to the user platform server. The above-mentioned smart fire hydrant monitoring system is used to monitor the water pressure of urban distributed fire hydrants to ensure that the equipment operates well. When a fault occurs or the water pressure fluctuates greatly, the competent unit is notified in time to locate the fault and maintain the equipment, which greatly reduces the cost of manpower inspections, and can achieve wide coverage monitoring and enhance the safety of the people. The smart fire hydrant can monitor the water pressure level of the fire hydrant in real time and issue an alarm reminder when the water pressure deviates from the normal range. This smart fire hydrant monitoring system based on long-distance communication technology has the advantages of low cost, easy installation, and simple maintenance. The manager transmits the collected information to the unified user terminal software management interface through the network to check the fire hydrants distributed in the entire area. This process fully realizes the centralized supervision of fire hydrants, and the pipeline pressure can be tested as needed.

[0029] The smart fire hydrant and the smart fire hydrant monitoring system of the utility model are implemented by arranging a temperature-pressure integrated sensor 200 and a liquid level sensor 300 on the inner side of the valve disc 180, and installing a positioning sensor 600, a gravity sensor 700 and a 4G transmission module 800 on the control circuit board 400. It is possible to detect the water pressure and water temperature of the fire-fighting water in the fire hydrant body 100 to ensure that the fire-fighting water can be used normally when a fire occurs. The liquid level sensor 300 can detect the leakage of the valve disc 180 to avoid overflow of the fire-fighting water when the fire hydrant is in an idle state. To reduce the waste of water resources, the positioning sensor 600 and the gravity sensor 700 can respectively realize the positioning and tilt detection functions of the fire hydrant. The temperature, water pressure, leakage, location information and tilt status of the fire hydrant are sent to the user platform through the 4G transmission module 800, so that the user can monitor and respond to the failure of the fire hydrant in real time in the background. Multiple sensors are used to detect the status of the fire hydrant. Compared with manual inspection and testing, the data collection is more accurate, and the simultaneous detection of multiple fire hydrants can be realized at one time. The detection is more comprehensive, which reduces the difficulty of maintenance and management of fire hydrants.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
