Description

Technical Field

[0001] This utility model relates to the field of fire hydrant technology, and in particular to a fire hydrant capable of monitoring water flow. Background Technology

[0002] With the acceleration of urbanization and the continuous increase in building density, fire safety has become an important issue concerning people's lives and property safety and social stability. As a key infrastructure of the urban fire protection system, fire hydrants play a crucial role in providing a rapid source of water for firefighting when a fire occurs. The reliability of their operation directly affects the efficiency and effectiveness of fire suppression.

[0003] Currently, traditional fire hydrants are mainly composed of basic components such as valve body, interface, and hydrant body. Their design focuses on meeting the water supply function and lacks the ability to monitor the water flow status in real time. In practical applications, due to long-term exposure to the outdoor environment, fire hydrants are susceptible to natural corrosion, human damage, or equipment aging, which can lead to malfunctions such as pipe rupture, valve damage, and water leakage, resulting in the fire hydrant being unable to supply water normally when a fire occurs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fire hydrant capable of monitoring water flow.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fire hydrant capable of monitoring water flow, comprising a hydrant body, a valve body connected to the hydrant body by a flange, a flange bend provided on the valve body, a hose connector provided on the hydrant body, a monitoring structure provided on the valve body, the monitoring structure mainly composed of a flange tube, the flange tube being connected to the valve body flange, one end of the flange tube being connected to the flange bend flange, a rotating shaft being rotatably connected to the flange tube via a bearing, an impeller being provided on the rotating shaft, a permanent magnet being fixedly connected to the rotating shaft, and a Hall sensor being fixedly connected to the flange tube.

[0006] The aforementioned components achieve the following effect: water flow drives the impeller to rotate, and the permanent magnet on the impeller shaft rotates synchronously with the impeller. When the permanent magnet rotates with the impeller to the vicinity of the Hall sensor, the change in the magnetic field triggers the Hall effect, outputting a weak electrical signal. After amplification and shaping, the electrical signal becomes a standard pulse. The processor calculates parameters such as flow rate and velocity by counting the pulse frequency and combining it with the impeller parameters. At this time, the system records the parameter range during normal water supply as reference data. When the fire hydrant is damaged, the water flow state will be abnormal. The impeller sensor can judge the fault through its characteristics. When the impeller sensor detects abnormal flow and the pressure sensor shows a sudden drop in water pressure, it can be judged as a serious leak or rupture. If the impeller speed is zero and the pressure does not change, it may be that the component is stuck or the pipe is completely blocked. This avoids the situation where fire hydrants are susceptible to natural corrosion, human damage, or equipment aging due to long-term exposure to the outdoor environment, resulting in pipe rupture, valve damage, water leakage, and other faults, which would prevent the fire hydrant from supplying water normally during a fire.

[0007] Preferably, the flange pipe has a detection port, and a baffle is slidably inserted into the detection port.

[0008] The aforementioned components achieve the following effects: the baffle can be slid down to open, allowing for convenient inspection and maintenance of the impeller through the inspection port.

[0009] Preferably, a sealing strip is fixedly connected to the baffle, and a clearance groove is provided on the flange pipe.

[0010] The effects achieved by the above components are as follows: when the baffle is closed, the sealing strip can improve the sealing performance, and the clearance groove can make way for the fixing rod.

[0011] Preferably, a limit block is rotatably connected to the flange pipe, and a fixing rod is fixedly connected to the baffle.

[0012] The effect achieved by the above components is that when the baffle is closed, the limiting block is rotated to lock onto the fixed rod, thereby limiting the baffle.

[0013] Preferably, the impeller is provided with an installation structure, which mainly consists of two installation blocks. The two installation blocks are fixedly connected to both ends of the impeller. The rotating shaft is provided with an installation groove, and the installation blocks are provided with sliding grooves. Two locking blocks are slidably connected in the sliding grooves, and locking slots are provided on the inner walls of both sides of the installation groove.

[0014] The aforementioned components achieve the following effect: by inserting a mounting block into the mounting slot and then sliding two locking blocks to engage with their corresponding slots, the impeller can be quickly installed; conversely, it can be disassembled for cleaning.

[0015] Preferably, a connecting block is slidably connected to the impeller, and two connecting rods are rotatably connected to the connecting block, the connecting rods being rotatably connected to the locking block.

[0016] The effect achieved by the above components is that the sliding connecting block allows the two connecting rods to drive the two locking blocks to slide closer together.

[0017] Preferably, a pull rod is fixedly connected to the connecting block, the pull rod is slidably inserted into the impeller, and a pull ring is rotatably connected to the pull rod.

[0018] The effect achieved by the above components is that the operator can pull the lever by pulling the ring, causing the connecting block to slide, which makes the disassembly of the impeller more convenient.

[0019] Preferably, a spring is fitted onto the pull rod, one end of the spring is fixedly connected to the connecting block, and the other end of the spring is fixedly connected to the impeller.

[0020] The effect achieved by the above components is as follows: when the mounting block is pushed into the mounting groove, the mounting groove will squeeze the inclined surfaces of the two locking blocks, causing them to slide into the sliding groove. At this time, the spring will be compressed and contracted. Therefore, when the locking block contacts the locking groove, the locking block will be locked into the corresponding locking groove under the action of the spring rebound force, making the installation operation more convenient.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting a monitoring structure, the water flow drives the impeller to rotate, and the permanent magnet on the impeller shaft rotates synchronously with the impeller. When the permanent magnet rotates with the impeller to the vicinity of the Hall sensor, the change in the magnetic field triggers the Hall effect, outputting a weak electrical signal. After amplification and shaping, the electrical signal becomes a standard pulse. The processor calculates parameters such as flow rate and velocity by counting the pulse frequency and combining it with the impeller parameters. At this time, the system records the parameter range during normal water supply as reference data. When the fire hydrant is damaged, the water flow state will be abnormal. The impeller sensor can judge the fault through characteristics. When the impeller sensor detects abnormal flow and the pressure sensor shows a sudden drop in water pressure, it can be judged as a serious leak or rupture. If the impeller speed is zero and the pressure does not change, it may be that the component is stuck or the pipe is completely blocked. This avoids the situation where fire hydrants are susceptible to natural corrosion, human damage, or equipment aging due to long-term exposure to the outdoor environment, resulting in pipe rupture, valve damage, water leakage, and other faults, which would prevent the fire hydrant from supplying water normally during a fire.

[0029] Example 1, as Figure 1 As shown, a fire hydrant capable of monitoring water flow includes a hydrant body 1, a valve body 2 connected to a flange on the hydrant body 1, a flange bend 3 on the valve body 2, and a hose connector 4 on the hydrant body 1.

[0030] Reference Figures 2 to 4The valve body 2 is equipped with a monitoring structure 5, which mainly consists of a flange pipe 51. The flange pipe 51 is connected to the flange of the valve body 2, and one end of the flange pipe 51 is connected to the flange of the flange bend pipe 3. A rotating shaft 52 is rotatably connected to the flange pipe 51 through a bearing. An impeller 53 is mounted on the rotating shaft 52, and a permanent magnet 54 is fixedly connected to the rotating shaft 52. A Hall sensor 55 is fixedly connected to the flange pipe 51. The water flow drives the impeller 53 to rotate, and the permanent magnet 54 on the shaft of the impeller 53 rotates synchronously with the impeller 53. When the permanent magnet 54 rotates with the impeller 53 to the vicinity of the Hall sensor 55, the change in the magnetic field triggers the Hall effect, outputting a weak electrical signal. The electrical signal is amplified and shaped into a standard pulse. The processor calculates parameters such as flow rate and velocity by counting the pulse frequency and combining it with the parameters of the impeller 53. At this time, the system records the parameter range during normal water supply as reference data. When a fire hydrant is damaged, the water flow state will be abnormal. The impeller 53 sensor can judge the fault through characteristics. When the impeller 53 sensor detects abnormal flow and pressure, The sensor indicates a sudden drop in water pressure, which can be identified as a serious leak or rupture. If the impeller 53 rotates to zero and the pressure does not change, it may be due to component jamming or complete pipe blockage. This avoids the situation where fire hydrants, due to long-term exposure to the outdoor environment, are susceptible to natural corrosion, human damage, or equipment aging, leading to pipe rupture, valve damage, water leakage, and other malfunctions that would prevent the fire hydrant from supplying water normally during a fire. A detection port 56 is provided on the flange pipe 51, and a baffle 57 is slidably inserted into the detection port 56, which can slide downwards. When the baffle 57 is opened, the impeller 53 can be easily inspected and maintained through the inspection port 56. A sealing strip 58 is fixedly connected to the baffle 57, and a clearance groove 511 is provided on the flange pipe 51. When the baffle 57 is closed, the sealing strip 58 can improve the sealing performance, and the clearance groove 511 can make way for the fixed rod 59. A limit block 510 is rotatably connected to the flange pipe 51, and a fixed rod 59 is fixedly connected to the baffle 57. When the baffle 57 is closed, the limit block 510 is rotated to lock onto the fixed rod 59, thus limiting the position of the baffle 57.

[0031] Reference Figure 2 and Figure 5The impeller 53 is provided with an installation structure 6, which mainly consists of two installation blocks 61. The two installation blocks 61 are fixedly connected to both ends of the impeller 53. The rotating shaft 52 has an installation groove 62, and the installation blocks 61 have sliding grooves 63. Two locking blocks 64 are slidably connected in the sliding grooves 63. The inner walls on both sides of the installation groove 62 have locking slots 65. Inserting one installation block 61 into the installation groove 62 and then sliding the two locking blocks 64 into the corresponding locking slots 65 allows for quick installation of the impeller 53. Conversely, it can be disassembled for cleaning. A connecting block 66 is slidably connected to the impeller 53, and two connecting rods 67 are rotatably connected to the connecting block 66. The connecting rods 67 are rotatably connected to the locking blocks 64. Sliding the connecting block 66 allows the two connecting rods 67 to drive the two... The two locking blocks 64 slide closer together. A pull rod 68 is fixedly connected to the connecting block 66. The pull rod 68 is slidably inserted into the impeller 53. A pull ring is rotatably connected to the pull rod 68. The operator pulls the pull rod 68 through the pull ring, causing the connecting block 66 to slide, which makes the disassembly of the impeller 53 more convenient. A spring 69 is sleeved on the pull rod 68. One end of the spring 69 is fixedly connected to the connecting block 66, and the other end of the spring 69 is fixedly connected to the impeller 53. When the mounting block 61 is pushed into the mounting groove 62, the mounting groove 62 will squeeze the inclined surfaces of the two locking blocks 64, causing them to slide into the sliding groove 63. At this time, the spring 69 will be compressed and contracted. Therefore, when the locking block 64 contacts the locking groove 65, the locking block 64 will be locked into the corresponding locking groove 65 under the action of the spring 69's rebound force, making the installation operation more convenient.

[0032] Working principle: Water flow drives impeller 53 to rotate. Permanent magnet 54 on the impeller 53 shaft rotates synchronously with impeller 53. When permanent magnet 54 rotates to the vicinity of Hall sensor 55, the change in magnetic field triggers the Hall effect, outputting a weak electrical signal. This signal is amplified and shaped into a standard pulse. The processor calculates parameters such as flow rate and velocity by counting the pulse frequency and combining it with impeller 53 parameters. At this time, the system records the parameter range during normal water supply as baseline data. When a fire hydrant is damaged, the water flow state will be abnormal. Impeller 53 sensor can identify the fault through its characteristics. When impeller 53 sensor detects abnormal flow and pressure sensor shows a sudden drop in water pressure, it can be judged as a serious leak or rupture. If impeller 53 speed is zero and pressure does not change, it may be due to component jamming or complete pipe blockage. This avoids situations where fire hydrants, due to long-term exposure to outdoor environments, are susceptible to natural corrosion, human damage, or equipment aging, leading to pipe rupture, valve damage, water leakage, etc., which can cause fire hydrants to be unable to supply water normally during a fire. (The last sentence appears to be an unrelated instruction and can be omitted.) Opening the baffle 57 allows for convenient inspection and maintenance of the impeller 53 through the inspection port 56. When the baffle 57 is closed, the sealing strip 58 improves the sealing performance, and the clearance groove 511 allows the fixing rod 59 to be moved. When the baffle 57 is closed, rotating the limiting block 510 locks it onto the fixing rod 59, limiting the baffle 57. Inserting an installation block 61 into the installation groove 62 and then sliding two locking blocks 64 into their corresponding locking slots 65 allows for quick installation of the impeller 53. Conversely, it can be disassembled for cleaning. The sliding connecting block 66... This allows the two connecting rods 67 to drive the two locking blocks 64 to slide closer together. The operator can pull the pull rod 68 through the pull ring to make the connecting block 66 slide, which makes the disassembly of the impeller 53 more convenient. When the mounting block 61 is pushed into the mounting groove 62, the mounting groove 62 will squeeze the inclined surfaces of the two locking blocks 64, causing them to slide into the sliding groove 63. At this time, the spring 69 will be compressed and contracted. Therefore, when the locking block 64 contacts the locking groove 65, the locking block 64 will be locked into the corresponding locking groove 65 under the action of the spring 69's rebound force, making the installation operation more convenient.
